An embodiment of the utility model provides an automatic change of lap equipment, including unwinding device, play first processing apparatus and splicing tape device.

Referring to fig. 1, the unwinding device is used for loading a work material roll A1 (see fig. 3) and a standby material roll A2 (see fig. 3), and driving the work material roll A1 to unwind the output work material strip B1 downstream. It should be noted that, in an embodiment of the present invention, the working material tape B1 and the standby material tape B2 may be membrane, that is, the working material roll A1 and the standby material roll A2 are membrane material rolls. Of course, in other embodiments, the working tape B1 and the spare tape B2 may be other types of tapes, and are not limited herein.

The head start processing device includes a support mechanism 21 and a pickup mechanism 22. The support mechanism 21 is located between the work material roll A1 and the standby material roll A2 of the unwinding device. The picking mechanism 22 is used for picking up a tape-up end B21 of the standby material roll A2 on the unwinding device, and drawing the tape-up end B21 (see fig. 3) to a position between the supporting mechanism 21 and the working material roll A1, so that the drawn-out standby material tape B2 is wound on the supporting mechanism 21.

Referring to fig. 1 to 3, the splicing device includes two splicing mechanisms 31, one of which carries an adhesive tape C. That is, when one of the two splicing mechanisms 31 carries the adhesive tape C, the other one does not carry the adhesive tape C. The splicing mechanism 31 carrying the adhesive tape C is used for pressing a first part of the adhesive tape C and the spare tape B2 to one side of the supporting mechanism 21, so that the first part of the adhesive tape C is bonded with the spare tape B2. The other splicing mechanism 31 not carrying the adhesive tape C is used for pressing the working tape B1 to the opposite other side of the supporting mechanism 21, cutting the working tape B1 from the upstream side of the supporting mechanism 21 (i.e. the lower side of the supporting mechanism 21 shown in fig. 5), and pressing the working tape B1 against the second part of the adhesive tape C from the downstream side of the supporting mechanism 21 (i.e. the upper side of the supporting mechanism 21 shown in fig. 5), so that the working tape B1 is bonded with the second part of the adhesive tape C. At this time, the working tape B1 and the spare tape B2 are bonded with the same adhesive tape C, and tape splicing is realized.

In the automatic roll changing device, in the actual production process, initially, the working material roll A1 and the standby material roll A2 are loaded on the unwinding device, and the working material roll A1 is driven to rotate to convey the working material belt B1 to the downstream. For convenience of description, the two splicing mechanisms 31 are respectively named a first splicing mechanism 31a and a second splicing mechanism 31b. Initially, the first splicing mechanism 31a carries the adhesive tape C. The second splicing mechanism 31b does not carry the adhesive tape C.

Referring to fig. 3 to 8, when unwinding of the roll of work material A1 is completed, an automatic roll change is required. First, the pick-up mechanism 22 picks up the starting end B21 of the standby material roll A2 on the unwinding device, and pulls the starting end B21 of the standby material roll A2 to reach between the support mechanism 21 and the work material roll A1, so that the pulled-out standby material roll B2 is wound on the support mechanism 21. At this time, the spare tape B2 between the support mechanism 21 and the spare roll A2 is a first spare tape section B22 (see fig. 5), and the spare tape B2 between the support mechanism 21 and the tape starting end B21 is a second spare tape section B23 (see fig. 5). Then, the first splicing mechanism 31a is controlled to move towards the supporting mechanism 21, so that the first splicing mechanism 31a presses the first part of the adhesive tape C and the first spare tape segment B22 thereon against one side of the supporting mechanism 21, i.e. the first part of the adhesive tape C is pasted on the spare tape B2. Then, the second tape splicing mechanism 31B is controlled to move toward the supporting mechanism 21, so that the second tape splicing mechanism 31B presses the working tape B1 and the second spare tape section B23 against the other side of the supporting mechanism 21.

Then, the second splicing mechanism 31B is controlled to cut the working tape B1 from the upstream side of the supporting mechanism 21, and the second splicing mechanism 31B is controlled to press the working tape B1 against the second portion of the adhesive tape C on the first splicing mechanism 31a from the downstream side of the supporting mechanism 21, so that the working tape B1 is bonded to the second portion of the adhesive tape C on the first splicing mechanism 31 a. At the moment, the first part of the adhesive tape C is bonded with the spare material tape B2, and the second part of the adhesive tape C is bonded with the working material tape B1, namely, the spare material tape B2 and the working material tape B1 are bonded together through the adhesive tape C, so that tape splicing is realized.

Then, the first splicing mechanism 31a and the second splicing mechanism 31b are controlled to move away from the support mechanism 21, respectively, in preparation for the next automatic reel change. At this time, the standby material roll A2 on the unwinding device is switched to the work material roll A1, and is driven to rotate by the unwinding device to continuously unwind and output the work material strip B1 downstream. Moreover, an empty material cylinder A3 (it should be noted that the material roll is formed by winding a material belt on the empty material cylinder A3, and the remaining material after the working material roll A1 is completely unreeled is the empty material cylinder A3) on the unreeling device can be replaced by a new material roll, and the new material roll is used as a standby material roll A2 to be switched to the working material roll A1 after the next automatic roll change. The next automatic roll change process is similar to the above roll change process, and is not limited herein.

Therefore, the utility model discloses an automatic change of lap equipment can realize that the automatic switch-over of work material book A1 and reserve material book A2 (automatic change of lap promptly) need not to adopt the manual work to change the lap, has reduced the cost of labor, and degree of automation is high, is favorable to improving production efficiency.

The work material roll A1 is a roll that is rotated by the unwinding device and conveys the work material roll B1 downstream. The work material tape B1 refers to the tape on the work material roll A1. The reserve roll A2 refers to a roll on the unwinding device that does not transport the web downstream. The reserve tape B2 refers to the tape on the reserve roll A2. It can be understood that after the automatic roll change, the standby roll A2 is switched to the working roll A1 to convey the working tape B1 downstream; meanwhile, the working material roll A1 is completely unreeled to form an empty material roll A3, and the empty material roll A3 may be replaced with a new material roll, which is the standby material roll A2.

It should be further noted that, in this document, the upstream and downstream of the supporting mechanism 21 are relative to the work material tape B1, that is, one end of the supporting mechanism 21 closer to the downstream of the work material tape B1 is a downstream end, and one end closer to the upstream of the work material tape B1 is an upstream end. In the embodiment shown in the drawings, the lower side of the support mechanism 21 is the upstream side, and the upper side of the support mechanism 21 is the downstream side.

Referring to fig. 8, it should be further noted that after the automatic roll changing is completed, an adhesive tape C is adhered to only one side of the joint of the working tape B1 and the spare tape B2, and a cut end of the working tape B1 and a tape start end B21 of the spare tape B2 are left at a side of the joint of the working tape B1 and the spare tape B2, which is away from the adhesive tape C, by a certain length. Because the material of diaphragm is lighter and softer, consequently adopt unilateral rubberizing, and the end of cutting off of work material area B1 and the material area of reserve material area B2 rise head end B21 overlength, can not influence the use of diaphragm yet.

In particular to the embodiment, the automatic roll changing device has a first roll changing state and a second roll changing state. When the automatic reel changer is in the first reel change state, the first splicing mechanism 31a carries an adhesive tape C. When the first splicing mechanism 31a and the second splicing mechanism 31B move to the supporting mechanism 21 and abut against the two opposite sides of the supporting mechanism 21, respectively, the first splicing mechanism 31a presses the first portion of the adhesive tape C and the first spare tape section B22 against one side of the supporting mechanism 21 (i.e., the right side of the supporting mechanism 21 as shown in fig. 5). The second splicing mechanism 31B presses the work tape B1 and the second spare tape section B23 against the other side of the support mechanism 21 (i.e., the left side of the support mechanism 21 as viewed in fig. 5). In this state, the second splicing mechanism 31B can be controlled to cut off the working tape B1, and the second splicing mechanism 31B can be controlled to press the working tape B1 against the second part of the adhesive tape C on the first splicing mechanism 31a, so that the working tape B1 and the spare tape B2 are adhesively connected by the adhesive tape C to complete splicing.

When the automatic reel changer is in the second reel change state, the second splicing mechanism 31b carries an adhesive tape C. When the first splicing mechanism 31a and the second splicing mechanism 31B move to the supporting mechanism 21 and abut against the two opposite sides of the supporting mechanism 21, respectively, the second splicing mechanism 31B presses the first portion of the adhesive tape C and the first spare tape section B22 against one side of the supporting mechanism 21 (i.e., the left side of the supporting mechanism 21 as shown in fig. 5). The first splicing mechanism 31a presses the work tape B1 and the second spare tape section B23 against the other side of the support mechanism 21 (i.e., the right side of the support mechanism 21 as viewed in fig. 5). In this state, the first splicing mechanism 31a can be controlled to cut off the working tape B1, and the first splicing mechanism 31a can be controlled to press the working tape B1 against the second portion of the adhesive tape C of the second splicing mechanism 31B, so that the working tape B1 and the spare tape B2 are adhesively connected by the adhesive tape C to complete splicing.

In particular embodiments, the support mechanism 21 is controllably movable in the first direction X between an avoidance position (i.e., the position in which the support mechanism 21 is located in fig. 4) and a splicing position (i.e., the position in which the support mechanism 21 is located in fig. 5). In the embodiment shown in fig. 3-7 in particular, the belt splicing position is located above the avoidance position. The unwinding device comprises two unwinding mechanisms 11 arranged at intervals along a second direction Y intersecting with the first direction X. The rolls loaded on the two unwinding mechanisms 11 may alternately be used as the work roll A1 and the standby roll A2, respectively. The picking mechanism 22 is controllably moved between the two unwinding mechanisms 11 to pull the tape starting end B21 to pass through between the avoiding position and the splicing position, so that the pulled spare tape B2 is located between the avoiding position and the splicing position, and the spare tape B2 is wound on the supporting mechanism 21 when the supporting mechanism 21 moves from the avoiding position to the splicing position. Preferably, the first direction X is perpendicular to the second direction Y. Specifically, in the embodiment shown in fig. 1, the first direction X is a vertical direction, and the second direction Y is a horizontal direction.

Referring to fig. 3 to 8, for convenience of description, the two unwinding mechanisms 11 are named as a first unwinding mechanism 11a and a second unwinding mechanism 11b, respectively. If the material roll on the first unwinding mechanism 11a is initially the work material roll A1, the work material strip B1 is conveyed downstream. The material roll on the second unwinding mechanism 11b is a standby material roll A2, and the first splicing mechanism 31a carries the adhesive tape C.

When the unwinding of the work material roll A1 on the first unwinding mechanism 11a is completed and an automatic roll change is required, first, the picking mechanism 22 moves toward the standby material roll A2 on the second unwinding mechanism 11B until the start end B21 of the tape on the standby material roll B2 is picked up (see fig. 3). Then, the pickup mechanism 22 moves leftward, thereby drawing the leading end B21 of the tape through between the escape position and the splicing position. Then, the supporting mechanism 21 is moved upward from the escape position to the splicing position, so that the backup tape B2 is wound around the upper side of the supporting mechanism 21 (see fig. 4). At this time, the part of the spare tape B2 between the support mechanism 21 and the spare roll A2 (i.e., the right side of the support mechanism 21) is a first spare tape segment B22; the portion of the spare tape B2 between the supporting mechanism 21 and the picking mechanism 22 (i.e., to the left of the supporting mechanism 21) is a second spare tape segment B23. Then, the first splicing mechanism 31a is controlled to move toward the support mechanism 21 at the splicing position, so that the first splicing mechanism 31a abuts against the right side of the support mechanism 21, and the first spare tape section B22 between the support mechanism 21 and the first splicing mechanism 31a is bonded to the first portion of the adhesive tape C (see fig. 5). Then, the second splicing mechanism 31B moves toward the supporting mechanism 21 at the splicing position, so that the second splicing mechanism 31B abuts against the left side of the supporting mechanism 21, and the supporting mechanism 21 and the second splicing mechanism 31B together press the working tape B1 and the second spare tape segment B23 (see fig. 6). Then, the second splicing mechanism 31B is controlled to cut the working tape B1 from the upstream side of the supporting mechanism 21, and the second splicing mechanism 31B is controlled to press the working tape B1 against the second portion of the adhesive tape C of the first splicing mechanism 31a from the downstream side of the supporting mechanism 21, so that the working tape B1 is bonded to the second portion of the adhesive tape C (see fig. 7). At this time, the right sides of the working material belt B1 and the spare material belt B2 are connected through the adhesive tape C in an adhesive mode, and therefore tape splicing is achieved. Finally, the first belt splicing mechanism 31a moves rightward to the initial position, the second belt splicing mechanism 31b moves leftward to the initial position, and the support mechanism 21 moves downward to the retracted position. At this time, the backup roll A2 on the second unwinding mechanism 11B is switched to the work roll A1, and the second unwinding mechanism 11B drives the work roll A1 thereon to rotate and continue to convey the work tape B1 downstream.

The empty cartridge A3 on the first unwinding mechanism 11a can be replaced with a new roll, which is used as the backup roll A2. Further, the second splicing mechanism 31b may be prepared for glue to prepare for the next automatic roll change.

When the unwinding of the work material roll A1 on the second unwinding mechanism 11B is completed and automatic roll change needs to be performed again, first, the picking mechanism 22 moves toward the standby material roll A2 on the first unwinding mechanism 11a until the start end B21 of the material strip on the standby material roll A2 is picked up. Then, the pickup mechanism 22 moves rightward, thereby drawing the leading end of the tape B21 to pass between the escape position and the splicing position. Then, the supporting mechanism 21 moves upward from the avoiding position to the splicing position, so that the standby tape B2 is wound on the upper side of the supporting mechanism 21. At this time, the portion of the spare tape B2 between the support mechanism 21 and the spare roll A2 (i.e., the left side of the support mechanism 21) is a first spare tape segment B22; the portion of the backup tape B2 between the supporting mechanism 21 and the picking mechanism 22 (i.e., the right side of the supporting mechanism 21) is a second backup tape segment B23. Then, the second joining mechanism 31B is controlled to move toward the support mechanism 21 at the joining position, so that the second joining mechanism 31B abuts against the left side of the support mechanism 21, and the first spare tape section B22 between the support mechanism 21 and the second joining mechanism 31B is bonded to the adhesive tape C. Then, the first splicing mechanism 31a moves to the supporting mechanism 21 at the splicing position, so that the first splicing mechanism 31a abuts against the right side of the supporting mechanism 21, and the supporting mechanism 21 and the first splicing mechanism 31a press the work tape B1 and the second spare tape section B23 together. Then, the first splicing mechanism 31a is controlled to cut the working tape B1 from the upstream side of the supporting mechanism 21, and the first splicing mechanism 31a is controlled to press the working tape B1 against the adhesive tape C of the second splicing mechanism 31B from the downstream side of the supporting mechanism 21, so that the working tape B1 is bonded to the adhesive tape C of the second splicing mechanism 31B. At this time, the left sides of the working material belt B1 and the spare material belt B2 are bonded through the adhesive tape C, and therefore tape splicing is achieved. Finally, the second belt splicing mechanism 31b moves leftward to the initial position, the first belt splicing mechanism 31a moves rightward to the initial position, and the support mechanism 21 moves downward to the retracted position. At this time, the backup roll A2 on the first unwinding mechanism 11a is switched to the work roll A1, and the first unwinding mechanism 11a rotates the work roll A1 thereon to continue to feed the work tape B1 downstream.

Alternatively, the picking mechanism 22 may move between the two unwinding mechanisms 11 by swinging or linear movement, so as to pick up the tape start end B21 on the reserve roll A2 and draw the picked tape start end B21 to pass through between the avoiding position and the splicing position.

Referring to fig. 1 and 2, in one embodiment, the picking mechanism 22 moves between the two unwinding mechanisms 11 in an oscillating manner, so as to reduce the occupied space near the supporting mechanism 21, and further leave enough space for the supporting mechanism 21 to cooperate with the two splicing mechanisms 31 for splicing. Further, the starting processing device further comprises a first swing mechanism 23 in driving connection with the picking mechanism 22, and the first swing mechanism 23 is used for driving the picking mechanism 22 to swing around a first swing axis between the two unwinding mechanisms 11.

Further, the first swing mechanism 23 includes a base 232, a first swing driving member 233 and a first swing arm 231. The first swing driving member 233 is disposed on the base 232, and one end of the first swing arm 231 is connected to an output shaft of the first swing driving member 233 to be driven by the first swing driving member 233 to rotate around a first swing axis. The other end of the first swing arm 231 is connected to the pick-up mechanism 22, so that the pick-up mechanism 22 swings around the first swing axis between the two unwinding mechanisms 11 following the first swing arm 231. Alternatively, the first swing driving member 233 may employ a motor. The first swing axis is perpendicular to both the first direction X and the second direction Y.

Referring to fig. 9 and 10, in an embodiment of the present invention, the picking mechanism 22 includes a mounting seat 221 and a clamping assembly 222 disposed on the mounting seat 221. The gripping assembly 222 has a first gripper 2221 and a second gripper 2223 arranged oppositely. The first clamping member 2221 and the second clamping member 2223 form a clamping space f therebetween for clamping the starting material end B21 of the backup roll A2, and at least one of the two members is movable toward or away from the other member, so as to clamp or release the starting material end B21. The mounting seat 221 is configured to controllably drive the first clamping member 2221 and the second clamping member 2223 to move to the standby reel A2, so as to clamp the tape start end B21, and drive the first clamping member 2221 and the second clamping member 2223 to pull the tape start end B21 to pass through between the avoiding position and the splicing position.

Thus, when the material take-up end B21 of the backup roll A2 needs to be picked up, first, the mounting seat 221 is controlled to move towards the backup roll A2 until the first clamping member 2221 and the second clamping member 2223 of the clamping assembly 222 are brought to abut against the backup roll A2, so that the material take-up end B21 on the backup roll A2 is located between the first clamping member 2221 and the second clamping member 2223 (the backup roll A2 can be driven to rotate by the unwinding mechanism 11 until the material take-up end B21 on the backup roll A2 is located between the first clamping member 2221 and the second clamping member 2223). Then, at least one of the first clamping member 2221 and the second clamping member 2223 is driven to approach the other one until the first clamping member 2221 and the second clamping member 2223 clamp the tape-out head end B21. Then, the mounting seat 221 is controlled to move towards a direction away from the standby material roll A2 until the leading end B21 of the drawn material strip passes through between the avoiding position and the splicing position, so that the standby material strip B2 is wound on the supporting mechanism 21 when the supporting mechanism 21 moves from the avoiding position to the splicing position, and then splicing is completed under the cooperation of the two splicing mechanisms 31.

In particular embodiments, the mounting seat 221 is controllably movable to a gripping position proximate to the reserve roll A2 and a pulling position away from the reserve roll A2. When the mounting seat 221 moves to the gripping position, the gripping assembly 222 grips the leading end B21 of the standby tape B2. When the mounting seat 221 moves to the drawing position, the gripping assembly 222 draws the gripped material take-up end B21 to pass through between the avoiding position and the splicing position.

Specifically, the mounting seat 221 is mounted at an end of the first swing arm 231 away from the first swing driving element 233 to swing between the two unwinding mechanisms 11 along with the first swing arm 231, so as to drive the clamping assembly 222 to clamp the tape start end B21 on the standby material roll A2, and draw the clamped tape start end B21 to pass through between the avoiding position and the splicing position.

Since the middle portion of the tape raising end B21 is initially fixed to the backup roll A2 by the connecting member B24 (e.g., a rubber strip, etc.), the corner portions B211 on both sides of the middle portion of the tape raising end B21 are in a free state. In order to accurately clamp the leading end B21 of the tape, in the embodiment, a side of the first clamping member 2221 facing the second clamping member 2223 has a second suction surface g1, and a side of the second clamping member 2223 facing the first clamping member 2221 has an air blowing surface g2. When the mounting seat 221 drives the first clamping piece 2221 and the second clamping piece 2223 to move to the material backup roll A2, the blowing surface g2 blows the corner part B211 of the material tape start end B21 toward the second adsorption surface g1 and is adsorbed by the second adsorption surface g 1. At least one of the first clamping member 2221 and the second clamping member 2223 approaches the other clamping member until the blowing surface g2 on the second clamping member 2223 clamps the corner portion B211 of the spare tape B2 on the second suction surface g1 of the first clamping member 2221. Thus, before the clamping, the blowing surface g2 on the second clamping member 2223 is used to blow the corner portion B211 of the tape start end B21 onto the second suction surface g1 of the first clamping member 2221, and the first clamping member 2221 and the second clamping member 2223 are used to clamp the corner portion B211 of the tape start end B21 adsorbed on the second suction surface g 1.

Preferably, first clamping member 2221 is stationary and second clamping member 2223 is movable toward and away from first clamping member 2221. Thus, when the material loading head end B21 is clamped, the blowing surface g2 on the second clamping member 2223 blows air, so that the corner portion B211 of the material loading head end B21 is blown onto the second adsorption surface g1 on the first clamping member 2221 and adsorbed by the second adsorption surface g 1. Then, the second clamping member 2223 is controlled to move closer to the first clamping member 2221 until the first clamping member 2221 and the second clamping member 2223 clamp the corner portion B211 of the head end B21 of the tape to be rolled between the air blowing surface g2 and the second adsorption surface g 1.

It should be noted that only the second clamping member 2223 moves close to the first clamping member 2221 to clamp the corner portion B211, and the first clamping member 2221 is fixed, so that the corner portion B211 is prevented from gradually separating from the second suction surface g1 when the first clamping member 2221 moves, and the clamped corner portion B211 is prevented from being unstable due to a small area.

Further, the second suction surfaces g1 and the blowing surfaces g2 each include two, that is, the first clamping member 2221 has two second suction surfaces g1 on a side facing the second clamping member 2223, and the second clamping member 2223 has two blowing surfaces g2 on a side facing the first clamping member 2221. The two second adsorption surfaces g1 and the two blowing surfaces g2 are arranged in one-to-one correspondence in the arrangement direction of the first holder 2221 to the second holder 2223 (i.e., in the left-to-right direction in fig. 9). That is, in the arrangement direction of the first holder 2221 to the second holder 2223, one of the second adsorption surfaces g1 is opposed to one of the blowing surfaces g2, and the other second adsorption surface g1 is opposed to the other blowing surface g2. In this way, when the mounting seat 221 moves towards the backup roll A2 until the first clamping member 2221 and the second clamping member 2223 of the clamping assembly 222 are brought into abutment with the backup roll A2, one corner portion B211 of the tape start end B21 is located between one set of the second opposing suction surface g1 and the air blowing surface g2, and the other corner portion B211 of the tape start end B21 is located between the other set of the second opposing suction surface g1 and the air blowing surface g2. At this time, the two blowing surfaces g2 blow air simultaneously, so that the two corner portions B211 are blown up onto the two second adsorption surfaces g1, respectively, and are adsorbed by the two second adsorption surfaces g1, respectively. Then, the second clamping member 2223 is controlled to move toward the first clamping member 2221 until the two blowing surfaces g2 on the second clamping member 2223 clamp the two corner portions B211 on the two second absorption surfaces g1, respectively, so as to further make the clamping of the tape-raising end B21 more stable.

Preferably, each second adsorption surface g1 is parallel to a corresponding blowing surface g2, so that the second adsorption surface g1 and the opposite blowing surface g2 are attached more tightly when the corner part B211 is clamped, and the clamping of the corner part B211 is more stable.

In the specific embodiment, in the arrangement direction from the first clamping member 2221 to the second clamping member 2223, the distance between the two blowing surfaces g2 is gradually reduced, and the distance between the two second adsorption surfaces g1 is also gradually reduced, so that the blowing surfaces g2 can blow up as much material as possible of the corner portion B211 onto the corresponding second adsorption surfaces g1, and further, as much material as possible of the corner portion B211 is clamped and fixed, and the clamping stability is further improved.

In some embodiments, the gripping assembly 222 is rotatably connected to the mounting base 221 about a rotation axis, and the arrangement direction of the first gripping member 2221 to the second gripping member 2223 is perpendicular to the rotation axis. In this way, the spatial angles of the first and

second clamping members

2221 and 2223 can be adjusted by controlling the rotation of the gripping assembly 222 around the rotation axis, so that when the first and

second clamping members

2221 and 2223 swing to the backup roll A2 following the mounting seat 221, the first and

second clamping members

2221 and 2223 are both abutted against the circumferential side surface of the backup roll A2, and the first and

second clamping members

2221 and 2223 are spaced along the circumferential direction of the backup roll A2, so that the first and

second clamping members

2221 and 2223 can accurately grip the tape start end B21 on the backup roll A2.

In one embodiment, the gripping assembly 222 further includes a rotating base 2225 and a gripping driving member 2226. The rotating base 2225 is rotatably coupled to the mounting base 221 about a rotation axis. The first clamping member 2221 is fixedly connected to the rotating base 2225, and the second clamping member 2223 is movably connected to the rotating base 2225 close to or far from the first clamping member 2221, so that the first clamping member 2221 and the second clamping member 2223 can rotate around the rotating axis along with the rotating base 2225, so as to adjust the spatial angle of the first clamping member 2221 and the second clamping member 2223, so as to accurately clamp the strip start end B21 on the standby material roll A2. The clamping driving member 2226 is disposed on the rotating base 2225 and is drivingly connected to the second clamping member 2223, so that the second clamping member 2223 can be driven to move toward or away from the first clamping member 2221 to clamp or release the strip start end B21. Alternatively, the gripping drive 2226 may be a cylinder.

It should be noted that, in other embodiments, the first clamping member 2221 may include two first sub-clamping members, and the second clamping member 2223 may also include two second sub-clamping members grouped in a one-to-one correspondence with the two first sub-clamping members. The two groups of first sub-clamping pieces and the second sub-clamping pieces are respectively used for clamping two corner parts B211 of the starting end B21 of the material belt. Wherein, two first sub-holders all fixed connection are on the roating seat 2225, and two second sub-holders all can be connected on the roating seat 2225 towards the first sub-holder that respectively corresponds is close to or is kept away from. Each first sub-clamping piece is provided with a second adsorption surface g1 towards one side corresponding to the second sub-clamping piece, and each second sub-clamping piece is provided with a blowing surface g2 towards one side corresponding to the first sub-clamping piece.

The gripping driving members 2226 include two gripping driving members 2226, which are both arranged on the rotating base 2225, and are respectively connected with the two second sub-gripping members in a driving manner. That is, one of the gripping and driving members 2226 is used to drive the blowing surface g2 of one of the second sub-grippers to approach or move away toward the second suction surface g1 of the corresponding first sub-gripper, so as to grip or release one of the corner portions B211; the other clamping driving member 2226 is used to drive the blowing surface g2 of the other second sub-clamping member to approach or move away from the second suction surface g1 of the corresponding first sub-clamping member, so as to clamp or release the other corner portion B211.

With continued reference to fig. 2, in one embodiment, the gripping assembly 222 further includes a rotary driving member 234, a driving wheel 235, a driven wheel 236, and a transmission belt (not shown). The rotary driving member 234 is mounted on the first swing arm 231, the driving wheel 235 is mounted on an output shaft of the rotary driving member 234, the driven wheel 236 is mounted on the rotary base 2225, and the transmission belt is sleeved between the driving wheel 235 and the driven wheel 236. Thus, when the space angle of the first clamping member 2221 and the second clamping member 2223 relative to the standby material roll A2 needs to be adjusted, the rotating driving member 234 drives the driving wheel 235 to rotate, the driving wheel 235 drives the driven wheel 236 to rotate through the transmission belt, the driven wheel 236 drives the rotating base 2225 to rotate, and the rotating base 2225 drives the first clamping member 2221 and the second clamping member 2223 to rotate.

In order to ensure that the picking mechanism 22 can accurately clamp the tape-up end B21, in one embodiment, the tape-up processing device further includes a detecting mechanism 23, and the detecting mechanism 23 is used for detecting the position of the tape-up end B21 on the reserve roll A2. In this way, before the automatic roll change, the unwinding device can be controlled to drive the stock roll A2 to rotate, and the detection mechanism 23 can be used to detect the position of the tape start end B21 on the stock roll A2. When the strip start end B21 rotates to the position facing the picking mechanism 22, the unwinding device controls the spare material roll A2 to stop rotating, so as to ensure that when the picking mechanism 22 moves to the position where the first clamping member 2221 and the second clamping member 2223 abut against the spare material roll A2, the strip start end B21 on the spare material roll A2 is located between the first clamping member 2221 and the second clamping member 2223, and further ensure that the first clamping member 2221 and the second clamping member 2223 can accurately clamp the strip start end B21. Alternatively, the detection mechanism 23 may employ a photoelectric sensor or an image sensor.

In some embodiments, each splicing mechanism 31 has a first abutting portion 310 and a second abutting portion 311 that can collectively carry an adhesive tape C. When the two splicing mechanisms 31 move to the splicing position, the splicing mechanism 31 carrying the adhesive tape C presses the adhesive tape C (i.e. the first part of the adhesive tape C) and the first spare tape section B22 to one side of the supporting mechanism 21 through the first abutting part 310 of the splicing mechanism 31; the other splicing mechanism 31 not carrying the adhesive tape C presses the work tape B1 to the other side of the support mechanism 21 through its first abutting portion 310, and presses the work tape B1 to the adhesive tape C (i.e., the second portion of the adhesive tape C) of the second abutting portion 311 of the splicing mechanism 31 carrying the adhesive tape C from the downstream side of the support mechanism 21 through its second abutting portion 311. In this way, the splicing mechanism 31 uses the first abutting portion 310 and the second abutting portion 311 to carry the adhesive tape C together, so that the first abutting portion 310 bonds the first part of the adhesive tape C to the spare tape B2, and the second abutting portion 311 bonds the second part of the adhesive tape C to the work tape B1, thereby realizing splicing.

In the specific embodiment, each tape splicing mechanism 31 further includes a cutting portion 312 for cutting off the work tape B1, and the cutting portion 312 is located on a side of the first abutting portion 310 away from the second abutting portion 311. In this way, when the tape splicing mechanism 31 presses the work tape B1 against the support mechanism 21 by the first abutting portion 310, the passing work tape B1 is cut by the cutting portion 312, and the work tape B1 is separated from the empty bobbin A3.

In some embodiments, the supporting mechanism 21 includes a supporting block 210 controllably movable in the first direction X, and both sides (i.e., the left and right sides in fig. 1) in the second direction Y of the supporting block 210 have first suction surfaces 2101 for sucking the reserve tape B2. The support mechanism 21 further includes a first support roller 212 rotatably provided on a side of the support block 210 facing the escape position (i.e., a lower side of the support block 210 in fig. 2). The splicing mechanism 31 has an abutment roller 313 (see fig. 3) rotatable about its axis.

As shown in fig. 6, when the splicing mechanism 31 moves to the splicing position, the abutting roller 313 on the splicing mechanism 31 abuts against the first supporting roller 212 of the supporting mechanism 21 at the splicing position, so as to press the first spare tape segment B22 or the working tape B1 together; the first abutting portions 310 of the splicing mechanism 31 are controllably moved toward the corresponding first suction surfaces 2101 to abut against each other, thereby pressing the first spare tape segment B22 or the work tape B1 against the corresponding first suction surfaces 2101.

In this way, during the reel change, the splicing mechanism 31 carrying the adhesive tape C moves to the splicing position, so that the abutment roller 313 of the splicing mechanism 31 presses the first spare tape section B22 of the spare tape B2 against the first support roller 212, and the first adsorption surfaces 2101 on both sides of the support block 210 respectively adsorb the first spare tape section B22 and the second spare tape section B23 of the spare tape B2, thereby preventing the spare tape B2 passing through the support mechanism 21 from swinging freely. At this time, the second clamping member 2223 is controlled to move away from the first clamping member 2221, so that the clamping of the strip start end B21 is released. The unwinding mechanism 11 controlling the loading of the backup roll A2 drives the backup roll A2 to rotate so as to gradually wind the backup tape B2 until the tape start end B21 moves to the first suction surface 2101 of the support block 210 to be sucked. Then, the first contact portion 310 of the splicing mechanism 31, which has attracted the tape C, presses the first spare tape segment B22 and the tape C against the first suction surface 2101 on the support block 210 side, so that the spare tape B2 is bonded to the portion of the tape C located on the first contact portion 310.

Then, the splicing mechanism 31 which does not adsorb the adhesive tape C is controlled to move to the splicing position, so that the abutting roller 313 on the splicing mechanism 31 presses the work tape B1 against the first supporting roller 212, and the first abutting portion 310 of the splicing mechanism 31 is controlled to press the work tape B1 and the tape leading end B21 against the first adsorption surface 2101 on the side of the supporting block 210 departing from the adhesive tape C. Then, the cutting portion 312 of the splicing mechanism 31 that does not absorb the adhesive tape C is controlled to cut the working tape B1, and the second abutting portion 311 of the splicing mechanism 31 that does not absorb the adhesive tape C is controlled to press the working tape B1 against the second abutting portion 311 of the splicing mechanism 31 that absorbs the adhesive tape C, so that the working tape B1 is bonded to the portion of the adhesive tape C located on the second abutting portion 311. Finally, the two belt splicing mechanisms 31 leave the supporting block 210 and return to the initial position, and the supporting block 210 moves to the avoiding position, so that the belt splicing is completed.

It should be noted that, in the process of changing the roll, before the tape splicing mechanism 31 which does not adsorb the adhesive tape C moves to the tape splicing position, a section of the spare tape B2 is wound, so that the tape leading end B21 of the spare tape B2 moves to the first absorbing surface 2101 on the side of the supporting block 210 which is away from the adhesive tape C, and thus the tape leading end B21 of the spare tape B2 is not cut when the working tape B1 is cut by the cutting portion 312 of the tape splicing mechanism 31 which does not adsorb the adhesive tape C, that is, waste of the spare tape B2 is avoided.

In the embodiment, the supporting mechanism 21 further includes a second supporting roller 213 rotatably mounted on a side of the supporting block 210 facing the splicing position (i.e., above the supporting block 210 shown in fig. 2). In this way, when the support mechanism 21 moves from the retracted position to the splicing position, the spare tape B2 is wound around the second support roller 213, thereby ensuring smooth winding of the spare tape B2 in the subsequent process.

In one embodiment, the supporting mechanism 21 includes a lifting assembly 214, and the supporting block 210 is mounted at a driving end of the lifting assembly 214, so that the lifting assembly 214 can drive the supporting block 210 to move along the first direction X to the avoiding position or the splicing position. The first supporting roller 212 and the second supporting roller 213 are rotatably connected to both sides of the supporting block 210 in the first direction X around their axes, respectively, and the first supporting roller 212 is located at a side of the supporting block 210 facing the retracted position (i.e., a lower side of the supporting block 210 shown in fig. 2), and the second supporting roller 213 is located at a side of the supporting block 210 facing the taping position (i.e., an upper side of the supporting block 210 shown in fig. 2). The two first suction surfaces 2101 are respectively located on both sides of the support block 210 in the second direction Y, and are both located between the first support roller 212 and the second support roller 213. Optionally, the first absorbing surface 2101 is provided with a plurality of absorbing holes communicated with an external negative pressure source, so as to absorb the material belt by using negative pressure. The lifting assembly 214 may be a pneumatic cylinder, an electric cylinder, or a linear module.

In the embodiment of the present invention, the belt splicing device further includes two second swing mechanisms 32 corresponding to the two belt splicing mechanisms 31 one to one. Each second swing mechanism 32 includes a second swing driving member 321 and a second swing arm 322. One end of the second swing arm 322 is connected to the driving end of the second swing driver 321, so as to be driven by the second swing driver 321 to rotate. The other end of the second swing arm 322 is connected to a corresponding tape splicing mechanism 31, so that the tape splicing mechanism 31 swings between the glue preparing position and the tape splicing position along with the second swing arm 322. In this way, the two splicing mechanisms 31 are driven by the two second swing mechanisms 32 to swing between the respective glue preparation positions and the splicing positions. When the two tape splicing mechanisms 31 swing to the tape splicing position, the tape splicing is completed by matching with the supporting mechanism 21. The two splicing mechanisms 31 swing to respective glue preparation positions to complete glue preparation (i.e., to provide the first abutting portion 310 and the second abutting portion 311 with the adhesive tapes C). Alternatively, the second swing driver 321 may employ a motor.

Note that, two splicing mechanisms 31 are respectively disposed on both sides of the support mechanism 21 in the second direction Y, and both the splicing mechanisms 31 swing toward the support mechanism 21 until reaching the splicing position. The two belt splicing mechanisms 31 are pivoted away from each other until they reach their respective glue preparation positions. Obviously, the glue preparation positions of the two tape splicing mechanisms 31 are not understood to be the same position, but are understood to be two different positions of the glue preparation positions of the two tape splicing mechanisms 31.

Specifically, in the embodiment, each belt splicing mechanism 31 includes a first driving member 314, a moving block 315, a second driving member 316, a first abutting portion 310, a second abutting portion 311, a third driving member 317, and a cutting portion 312. The first driving member 314 is mounted on the second swing arm 322, and the moving block 315 is disposed at the driving end of the first driving member 314, so that the first driving member 314 can drive the moving block 315 to move. The second drive member 316, the first abutment 310 and the third drive member 317 are all mounted on the moving block 315 such that the second drive member 316, the first abutment 310 and the third drive member 317 follow the moving block 315 for movement therewith. The second abutting portion 311 is provided at the driving end of the second driver 316 so that the second driver 316 can drive the second abutting portion 311 to move. The cutting portion 312 is disposed at the driving end of the third driving member 317, so that the third driving member 317 can drive the cutting portion 312 to move, thereby completing the cutting action.

When the second swing arm 322 drives the tape splicing mechanism 31 to swing to the tape splicing position, the first driving member 314 drives the moving block 315 to extend out along the second direction Y so as to drive the first abutting portion 310 to compress the tape (the working tape B1 or the spare tape B2) on one side of the supporting mechanism 21, the third driving member 317 can drive the cutting portion 312 to cut off the working tape B1 from the upstream side of the supporting mechanism 21, and the second driving member 316 can drive the second abutting portion 311 to extend out along the second direction Y so as to press the working tape B1 on the downstream side of the supporting mechanism 21 against the opposite side of the supporting mechanism 21 until the working tape B1 is adhered to the tape C. Alternatively, the first, second and

third drivers

314, 316, 317 may be cylinders. The first abutting portion 310 and the second abutting portion 311 may be abutting blocks, and the cutting portion 312 may be a cutter.

Referring to fig. 11 and 12, in an embodiment, the tape splicing apparatus further includes a tape preparing mechanism 33, and the tape preparing mechanism 33 is used for preparing the adhesive for the tape splicing mechanism 31 swung to the adhesive preparing position (i.e. the adhesive tape C is adsorbed on the first abutting portion 310 and the second abutting portion 311). The glue preparing mechanism 33 includes a movable base 331 and a glue supplying assembly 336 disposed on the movable base 331, wherein the glue supplying assembly 336 has a glue supplying suction cup 3361 for sucking the adhesive tape C, and the glue supplying suction cup 3361 is controllably movable along a first predetermined direction. The movable base 331 can be controllably moved to the glue preparing position of each tape splicing mechanism 31; when the movable base 331 moves to the adhesive preparing position of any one of the splicing mechanisms 31, the adhesive supplying cup 3361 and the first abutting portion 310 and the second abutting portion 311 of the splicing mechanism 31 that moves to the adhesive preparing position are arranged in the first predetermined direction, so that the adhesive supplying cup 3361 can move toward the first abutting portion 310 and the second abutting portion 311 along the first predetermined direction until the first abutting portion 310 and the second abutting portion 311 suck the adhesive tape C on the adhesive supplying cup 3361. Optionally, the first preset direction is parallel to the first direction X.

Further, the first contact portion 310 and the second contact portion 311 each have a third suction surface d1. When the second driving member 316 drives the second abutting portion 311 to retract, the two third suction surfaces d1 of the first abutting portion 310 and the second abutting portion 311 are flush with each other to form a glue suction surface d together, so that the adhesive tape C on the glue feeding sucker 3361 can be sucked by using the glue suction surface d. When the second swing arm 322 drives the tape splicing mechanism 31 to swing to the glue preparation position, two third adsorption surfaces d1 parallel and level of the first abutting part 310 and the second abutting part 311 are formed together to form a glue adsorption surface d, and the glue adsorption surface d is opposite to the glue supply sucker 3361 which moves to the glue preparation position in the first preset direction, so that the glue supply sucker 3361 can move towards the first abutting part 310 and the second abutting part 311 along the first preset direction, and the adhesive tape C on the glue supply sucker 3361 is sucked up to the glue adsorption surface d.

In an embodiment, the glue preparing mechanism 33 further includes a tape unwinding assembly 333, a glue clamping assembly 334, a glue cutting assembly 335, and a glue pulling assembly 337 mounted on the movable base 331.

The tape unwinding assembly 333 is used for unwinding the output tape h to the laminating assembly 334, and the laminating assembly 334 can controllably clamp or release the passing tape h. The glue supply suction cup 3361 is located at the downstream side of the glue clamping assembly 334 and is used for sucking the passing adhesive tape strip h. The pulling assembly 337 is configured to controllably grip a strip of adhesive tape h passing through the laminating assembly 334 and pull the strip of adhesive tape h to a side of the supply suction cup 3361 facing away from the laminating assembly 334. The glue cutting assembly 335 is located between the glue clamping assembly 334 and the glue supplying suction cup 3361, and is used for cutting off the passing adhesive tape strip h.

Thus, when the adhesive tape C is needed on the adhesive supplying suction cup 3361, firstly, the head of the adhesive tape strip h is clamped by the adhesive clamping assembly 334, and the adhesive pulling assembly 337 is controlled to move towards the adhesive clamping assembly 334 until the head of the adhesive tape strip h on the adhesive clamping assembly 334 is clamped. Then, the doubling assembly 334 releases the tape h, and the tape pulling assembly 337 is controlled to pull the tape h past the tape supplying suction cup 3361 until reaching a side of the tape supplying suction cup 3361 away from the doubling assembly 334. Then, the glue clamping assembly 334 clamps the tape h, the glue supplying suction cups 3361 adsorb the tape h passing through, the glue cutting assembly 335 is controlled to cut the tape h between the glue clamping assembly 334 and the glue supplying suction cups 3361, the glue pulling assembly 337 is loosened, and at this time, the part adsorbed on the glue supplying suction cups 3361 is the tape C.

In an embodiment, the glue supply assembly 336 further includes a glue supply driving part 3362 mounted on the movable base 331 and a glue supply driving part 3363 mounted at a driving end of the glue supply driving part 3362.

The glue supplying driving member 3363 is drivingly connected to the glue supplying suction cup 3361 to drive the glue supplying suction cup 3361 to move along a first predetermined direction. In this way, when the adhesive tape C needs to be supplied to the splicing mechanism 31 moved to the adhesive preparation position, first, the moving base 331 is moved to the adhesive preparation position, and the adhesive supply driving member 3363 and the adhesive supply suction pad 3361 are driven by the adhesive supply driving member 3362 to move in the second predetermined direction until the adhesive supply suction pad 3361 is opposite to the first abutting portion 310 and the second abutting portion 311 of the splicing mechanism 31 in the first predetermined direction. Then, the glue feeding suction cup 3361 is driven by the glue feeding driving member 3363 to move in the first predetermined direction until the adhesive tape C is fed onto the first abutting portion 310 and the second abutting portion 311 of the tape splicing mechanism 31. Alternatively, the glue supply driving member 3363 may employ an air cylinder.

Specifically, in the embodiment shown in fig. 11, the first predetermined direction is an up-down direction, and the second predetermined direction is a direction perpendicular to the paper surface.

The glue supplying driving element 3363 is disposed at a driving end of the second movable driving element 3365, so as to be driven by the second movable driving element 3365 to move along a second predetermined direction. In this way, the first movable driving element 3364 and the second movable driving element 3365 drive the glue supply driving element 3363 and the glue supply sucking disc 3361 to move along the second preset direction, so that the stroke of the glue supply sucking disc 3361 is ensured to meet the requirement on one hand; on the other hand, compared with the driving member with a large stroke, the driving member with two smaller strokes is adopted to replace the driving member with a large stroke in the embodiment, so that the occupied space is saved, and the structure is more compact. Alternatively, both the first and second

movable drives

3364 and 3365 may employ air cylinders.

It should be noted that, of course, in other embodiments, only one moving driving member may be provided for the glue supplying driving member 3362, and three or more moving driving members may be provided as long as the glue supplying suction cup 3361 can be driven to move along the second preset direction and the requirement of the stroke is met, which is not limited herein.

In specific embodiments, the glue clamping assembly 334 includes a clamping jaw air cylinder installed on the moving base 331 and a clamping jaw installed at a driving end of the clamping jaw air cylinder, and the clamping jaw air cylinder drives the clamping jaw to clamp or loosen the passing adhesive tape strip h.

In an embodiment, the glue cutting assembly 335 includes a glue cutting cylinder mounted on the movable base 331 and a glue cutting knife mounted at a driving end of the glue cutting cylinder, and the glue cutting cylinder drives the glue cutting knife to cut off the passing adhesive tape strip h. Of course, in other embodiments, other types of cutting structures may be adopted, as long as the passing adhesive tape strips h can be cut, and the cutting is not limited herein.

In one embodiment, the glue pulling assembly 337 includes a glue pulling driving member 3371, a glue pulling slide 3372, a glue pulling jaw cylinder 3373, and a glue pulling jaw 3374. The glue drawing driving part 3371 is arranged on the movable base 331, and the glue drawing sliding base 3372 is arranged at the driving end of the glue drawing driving part 3371, so that the glue drawing driving part 3371 can drive the glue drawing sliding base 3372 to move. A pulling glue gripper cylinder 3373 is mounted on the pulling glue slide 3372 to move with the pulling glue slide 3372. The glue pulling clamping jaw 3374 is arranged at the driving end of the glue pulling clamping jaw cylinder 3373, so that the glue pulling clamping jaw cylinder 3373 can drive the glue pulling clamping jaw 3374 to clamp or loosen the adhesive tape strip h. Thus, when the tape h needs to be pulled out, firstly, the pulling driving part 3371 drives the pulling sliding seat 3372 to move close to the glue clamping assembly 334 until the pulling clamping jaw cylinder 3373 can drive the pulling clamping jaw 3374 to clamp the tape h at the glue clamping assembly 334. Then, the doubling assembly 334 releases the tape h, and the tape pulling driving part 3371 drives the tape pulling slide 3372 to move away from the doubling assembly 334 until reaching the side of the tape supplying suction cup 3361 away from the doubling assembly 334, thereby completing the tape pulling.

The glue pulling driving member 3371 may be a linear driving module, such as a motor lead screw module or an electric cylinder, which is not limited herein.

In some embodiments, the splicing device further comprises a cartridge handling mechanism 35 and a cartridge collection mechanism 34 (see fig. 1), the cartridge handling mechanism 35 being mounted on the movable mount 331. The cartridge collecting mechanism 34 is arranged in a first position and the unwinding device comprises two unwinding mechanisms 11 arranged in a second position and a third position, respectively.

The movable base 331 is controllably movable between a first position, a second position, and a third position. When the movable base 331 moves to the second position or the third position, the cartridge carrying mechanism 35 grips the empty cartridge A3 on the corresponding unwinding mechanism 11. When the moving base 331 moves to the first position, the cartridge carrying mechanism 35 transfers the gripped empty cartridge A3 to the cartridge collecting mechanism 34. So, realized automatic carrying empty feed cylinder A3 on unwinding mechanism 11 to the feed cylinder and collected 34 on, further reduced the cost of labor, promoted degree of automation.

In particular embodiments, the cartridge handling mechanism 35 comprises a handling drive assembly and a clamping assembly 356. The carrying driving assembly is mounted on the moving base 331, and the clamping assembly 356 is mounted at a driving end of the carrying driving assembly to be driven by the carrying driving assembly to move along an axial direction of the unreeling shaft of the unreeling mechanism 11. The clamping assembly 356 is used to clamp or unclamp the empty cartridge A3. Thus, when the movable base 331 moves to the second position or the third position, the carrying driving assembly drives the clamping assembly 356 to approach the empty cartridge A3 on the unwinding shaft of the unwinding mechanism 11 until the clamping assembly 356 clamps the empty cartridge A3. Then, the carrying driving assembly drives the clamping assembly 356 to move along the axial direction of the unwinding shaft until the clamping assembly 356 drives the empty cartridge A3 to be detached from the unwinding shaft of the unwinding mechanism 11. Then, the moving base 331 moves to the first position, and the transport driving assembly drives the gripper assembly 356 to move toward the cartridge collecting mechanism 34 until the empty cartridge A3 is placed on the cartridge collecting mechanism 34. Then, the gripper assembly 356 releases the grip on the empty cartridge A3 and moves away from the cartridge collection mechanism 34 under the drive of the transport drive assembly to prepare for the next transport of the empty cartridge A3.

Optionally, the handling drive assembly comprises a first handling drive 351, a first drive plate 352, a second handling drive 353 and a second drive plate 354. The first conveying driving member 351 is mounted on the moving seat 331, and the first driving plate 352 is mounted at the driving end of the first conveying driving member 351, so that the first conveying driving member 351 can drive the first driving plate 352 to move along the axial direction of the unreeling shaft of the unreeling mechanism 11. The second conveyance driver 353 is mounted on the first driving plate 352 to move together with the first driving plate 352. The second driving plate 354 is mounted at a driving end of the second conveyance driver 353 so that the second conveyance driver 353 can drive the second driving plate 354 to move in the axial direction of the unwinding shaft of the unwinding mechanism 11. The clamp assembly 356 is mounted on the second drive plate 354 such that the clamp assembly 356 can move with the second drive plate 354.

In this way, when the movable base 331 moves to the second position or the third position, the first conveying driving element 351 or the second conveying driving element 353 drives the clamping assembly 356 to approach the empty cartridge A3 on the unwinding shaft of the unwinding mechanism 11 until the clamping assembly 356 clamps the empty cartridge A3. Then, the first conveying driving member 351 or the second conveying driving member 353 drives the clamping assembly 356 to move along the axial direction of the unwinding shaft until the clamping assembly 356 drives the empty cartridge A3 to be detached from the unwinding shaft of the unwinding mechanism 11. Then, the moving base 331 is moved to the first position, and the first and

second conveyance drivers

351 and 353 drive the gripper assembly 356 to move toward the cartridge collection mechanism 34 until an empty cartridge A3 is placed on the cartridge collection mechanism 34. Then, the clamp assembly 356 releases the clamp of the empty cartridge A3 and moves away from the cartridge collection mechanism 34 by the first and second transport drives 351, 353 in preparation for the next empty feed pass. Alternatively, both the first and

second conveyance drivers

351 and 353 may employ air cylinders. The clamping assembly 356 may be a pneumatic clamping jaw, an electric clamping jaw, or the like, as long as clamping and unclamping of the empty cartridge A3 can be achieved, and is not limited herein.

Of course, it is not limited to the use of two carrier drives to form a two-stage drive to clamp assembly 356. In other embodiments, only one transport drive may be provided to drive the movement of the clamp assembly 356 (i.e., a single stage drive). In other embodiments, three or more handling actuators may be provided, without limitation.

In an embodiment, the glue preparing mechanism 33 further includes a moving driving component 332, and the moving driving component 332 is drivingly connected to the moving base 331 to drive the moving base 331 to move along the second direction Y, so that the moving base 331 passes through the first position, the second position, the third position, and the respective glue preparing positions of the two tape splicing mechanisms 31. It will be appreciated that when the movable seat 331 is moved to the first position, the cartridge handling mechanism 35 places an empty cartridge A3 on the cartridge collection mechanism 34; when the moving base 331 moves to the second position or the third position, the cartridge handling mechanism 35 takes down the empty cartridge A3 on the unwinding shaft of the corresponding unwinding mechanism 11; when the movable base 331 moves to the glue preparing position of one of the tape splicing mechanisms 31, the glue preparing mechanism 33 prepares glue on the glue absorbing surfaces d of the first abutting portion 310 and the second abutting portion 311 of the tape splicing mechanism 31; when the movable base 331 moves to the glue preparing position of the other splicing mechanism 31, the glue preparing mechanism 33 prepares glue on the glue absorbing surfaces d of the first abutting portion 310 and the second abutting portion 311 of the splicing mechanism 31.

It should be noted that the moving driving assembly 332 may be a linear driving module, such as a motor screw module or an electric cylinder, which is not limited herein.

Referring to fig. 13 to 15, in some embodiments, the cartridge collecting mechanism 34 includes a connecting seat 340 and a material collecting shaft 341. The receiving shaft 341 is connected to the connecting seat 340, and has a fixed end 3412 and a receiving end 3411 as longitudinal ends thereof. When the barrel transporting mechanism 35 moves to the first position, the empty barrel A3 clamped by the clamping assembly 356 is aligned with the material receiving end 3411 of the material receiving shaft 341, so that the first transporting driving element 351 and the second transporting driving element can sleeve the empty barrel A3 on the material receiving shaft 341 when the clamping assembly 356 is driven by the first transporting driving element 351 and the second transporting driving element to move along the axial direction of the material receiving shaft 341 to the material receiving shaft 341. When the empty cartridge A3 is moved into position along the take-up shaft 341, the gripper assembly 356 releases the empty cartridge A3 and returns under the drive of the first and second transport drives 351, 341.

Specifically, in one embodiment, when the movable base 331 moves to the second position or the third position, first, the first conveying driving member 351 or the second conveying driving member 353 drives the clamping assembly 356 to approach the empty cartridge A3 on the unwinding shaft of the unwinding mechanism 11 until the clamping assembly 356 clamps the empty cartridge A3. Then, the first conveying driving member 351 or the second conveying driving member 353 drives the clamping assembly 356 to move along the axial direction of the unwinding shaft until the clamping assembly 356 drives the empty cartridge A3 to be detached from the unwinding shaft of the unwinding mechanism 11.

When the barrel transporting mechanism 35 moves to the first position, first, the first transporting driving member 351 and the second transporting driving member 353 drive the clamping assembly 356 to move toward the material receiving shaft 341 along the axial direction of the material receiving shaft 341, so that the empty barrel A3 clamped by the clamping assembly 356 is sleeved on the material receiving shaft 341 from the material receiving end 3411 of the material receiving shaft 341. Then, the gripper assembly 356 releases the empty cartridge A3, and the first and

second conveyance drivers

351 and 353 drive the gripper assembly 356 back until it comes out of the receiving end 3411 of the receiving shaft 341, so that the next empty cartridge A3 is conveyed.

It should be noted that the stroke of the gripping assembly 356 when empty cartridge A3 is gripped in the second or third position is different from when empty cartridge A3 is released in the first position, and therefore the first and second transport drives 351, 353 are provided to meet the different stroke requirements. That is, the required stroke of the clamping assembly 356 is met by the first transport drive 351 or the second transport drive 353 in the second position or the third position, and the required stroke of the clamping assembly 356 is met by the first transport drive 351 and the second transport drive 353 in combination in the first position.

In particular embodiments, the cartridge collection mechanism 34 further comprises a sliding sleeve 342, a connecting rod 343, and a pull handle 344. The material receiving shaft 341 is a hollow shaft and is provided with a sliding groove extending lengthwise along the axial direction thereof. The sliding sleeve 342 is disposed in the material receiving shaft 341 and is movable along the axial direction of the material receiving shaft 341. The sliding sleeve 342 has a pushing portion 3421, and the pushing portion 3421 extends from the sliding groove to the circumferential surface of the material receiving shaft 341, so that when the sliding sleeve 342 moves from the fixed end 3412 to the material receiving end 3411 of the material receiving shaft 341, the pushing portion 3421 can push the empty material cartridges A3 on the material receiving shaft 341 to move toward the material receiving end 3411 until each empty material cartridge A3 is sequentially discharged from the material receiving end 3411. The connecting rod 343 is disposed in the material receiving shaft 341, and one end of the connecting rod 343 is connected to the sliding sleeve 342, and the other end of the connecting rod 343 extends to the material receiving end 3411 and is connected to the handle 344.

Thus, when the empty cartridges A3 on the material receiving shaft 341 are full, the empty cartridges A3 on the material receiving shaft 341 need to be unloaded, the handle 344 is pulled out first, so that the connecting rod 343 drives the sliding sleeve 342 to move to the material receiving end 3411, and the material pushing part 3421 of the sliding sleeve 342 pushes the empty cartridges A3 on the material receiving shaft 341 to move to the material receiving end 3411 until the empty cartridges A3 on the material receiving shaft 341 are sequentially separated from the material receiving end 3411, thereby completing the unloading.

Further, the cartridge collecting mechanism 34 further includes a guide rod 345 disposed in the material receiving shaft 341, and both ends of the guide rod 345 are connected to the material receiving end 3411 and the fixed end 3412, respectively. The sliding sleeve 342 is sleeved on the guide rod 345, so that the sliding sleeve 342 is guided along the axial direction of the material collecting shaft 341 by the guide rod 345.

Further, the cartridge collection mechanism 34 also includes a first sensor 346 and a detection bar 348. The first sensor 346 is installed on the connection base 340, and the sensing rod 348 is installed on the sliding sleeve 342. When the sliding sleeve 342 is moved to the fixed end 3412, the first sensor 346 can detect the detection rod 348. Thus, when the first sensor 346 detects the detecting rod 348, it indicates that the sliding sleeve 342 has moved to the fixed end 3412, and the receiving shaft 341 can receive the empty cartridge A3 conveyed by the cartridge conveying mechanism 35. Optionally, the first sensor 346 may be a photoelectric sensor or a proximity sensor.

Further, the cartridge collecting mechanism 34 further includes a second sensor 347 mounted on the coupling seat 340, the second sensor 347 being capable of detecting the empty cartridge A3 moved to the fixed end 3412. Thus, when the second sensor 347 detects an empty cartridge A3 moved to the fixed end 3412, indicating that the empty cartridge A3 on the take-up shaft 341 is full, the pull tab 344 needs to be pulled to unload the empty cartridge A3. Alternatively, the second sensor 347 may be a photosensor.

Further, the cartridge collecting mechanism 34 further includes a blocking block 349 installed at the fixed end 3412 of the material receiving shaft 341, and the blocking block 349 is used to perform a blocking limit on the empty cartridge A3 moving to the fixed end 3412.

Referring to fig. 16 to 17, in an embodiment of the present invention, each unwinding mechanism 11 includes an unwinding assembly 13 and a material shifting assembly 14. The unwinding assembly 13 includes a carrying base 131, a carrying shaft 132 and an unwinding shaft. The carrying shaft 132 is mounted on the carrying base 131, and the unwinding shaft is coaxially disposed on the carrying shaft 132 and has a mounting section 1331 and an unwinding section 1332. The unreeling shaft is rotatable about its own axis and axially movable relative to the carrying shaft 132. In the process that the unreeling shaft moves axially relative to the carrying shaft 132, the unreeling section 1332 can be driven to axially butt joint with or separate from the carrying shaft 132. The carrying shaft 132 is used for carrying one or more stock rolls A2 in the axial direction, and the material poking assembly 14 is used for poking the stock roll A2 on the carrying shaft 132 to move towards the unwinding section 1332 until the foremost stock roll A2 is poked onto the unwinding section 1332.

Thus, when the cartridge carrying mechanism 35 carries the empty cartridge A3 on the unwinding section 1332 of the unwinding shaft away, the material poking assembly 14 pokes a spare roll A2 on the carrying shaft 132 to the unwinding section 1332 of the unwinding shaft. After the automatic roll change is completed, the standby material roll A2 on the unwinding section 1332 is switched to be the working material roll A1, and is driven by the unwinding shaft to rotate, so that the working material belt B1 is unwound and output downstream.

In an embodiment, the unwinding mechanism 11 further includes an unwinding driving assembly disposed on the carrying base 131. The carrying shaft 132 is a hollow shaft, the unreeling shaft is inserted into the carrying shaft 132, and the unreeling section 1332 is extended out from one end of the carrying shaft 132. One end of the mounting section 1331 facing away from the unwinding section 1332 is in driving connection with the unwinding driving assembly, so that the unwinding driving assembly can drive the unwinding shaft to move axially or rotate around the axis of the unwinding shaft. Thus, when the standby material roll A2 needs to be shifted to the unwinding section 1332 of the unwinding shaft, the unwinding driving assembly drives the unwinding shaft to move axially until the unwinding section 1332 is axially abutted to the bearing shaft 132. The standby material roll A2 on the carrying shaft 132 is then shifted to the unwinding section 1332 by the shifting assembly 14. Then, the unreeling driving assembly drives the unreeling shaft to move reversely in the axial direction, so that the unreeling section 1332 is separated from the bearing shaft 132, and the bearing shaft 132 is prevented from causing adverse effects on the unreeling process of the unreeling shaft. When the material needs to be unreeled, the unreeling driving assembly drives the unreeling shaft to rotate, so that the work material roll A1 on the unreeling section 1332 is driven to rotate to realize unreeling.

In one embodiment, the unwinding driving assembly includes a separating base 134, an unwinding driving member 136 and a separating driving member 135. The release seat 134 is movably coupled to the carrier seat 131 in an axial direction of the carrier shaft 132. The unwinding driving member 136 is installed on the separating seat 134 and is in driving connection with the installation section 1331 to drive the unwinding shaft to rotate. The separating driving member 135 is mounted on the bearing seat 131 and is in driving connection with the separating seat 134 to drive the separating seat 134 to move axially along the bearing shaft 132, so as to drive the unreeling driving member 136 and the unreeling shaft to move axially along the unreeling shaft, thereby realizing axial butt joint and separation of the unreeling section 1332 of the unreeling shaft and the bearing shaft 132. Alternatively, the unwinding driving member 136 may be a motor, and the separating driving member 135 may be a cylinder.

Optionally, the unwinding drive assembly further includes a driving gear 1361 and a driven gear, the driving gear 1361 is installed at the driving end of the unwinding drive 136, and the driven gear is installed at the installation section 1331 of the unwinding shaft and engaged with the driving gear 1361. So, unreel driving piece 136 drive driving gear 1361 rotatory, driving gear 1361 drives driven gear rotatory, and driven gear drives the axle rotation of unreeling, and then realizes unreeling.

Alternatively, a slide rail and slider structure may be disposed between the carrier seat 131 and the separation seat 134, and the slide rail and slider structure may be used to guide the movement of the separation seat 134 relative to the carrier seat 131.

In some embodiments, the unwind assembly 13 further includes a stop structure including a stop 1371. The carrying shaft 132 has a mounting groove 1321 on a circumferential side surface near an end of the unwinding section 1332. The stop block 1371 is disposed in the mounting groove 1321 and is controllably movable in a radial direction of the bearing shaft 132 to a stop position and a loading position. When the stop block 1371 is located at the stop position, the stop block 1371 protrudes from the circumferential side of the carrying shaft 132 to block the standby roll A2 on the carrying shaft 132 from moving toward the unwinding section 1332. When the stop 1371 is at the feeding position, the stop 1371 is retracted into the carrying shaft 132 to allow the standby roll A2 on the carrying shaft 132 to move toward the unwinding section 1332.

Referring to fig. 18 to 19, in an embodiment, the stop structure further includes a first wedge block 1374, a second wedge block 1373 and a stop driver 1372 (see fig. 17). The first wedge block 1374 is installed in the installation groove 1321 of the bearing shaft 132 and has a first inclined surface L1 inclined with respect to the axial direction of the bearing shaft 132. Second wedge block 1373 and first inclined plane L1 sliding fit to with stopper 1371 along the radial butt of bearing axle 132, thereby make second wedge block 1373 along the axial displacement of bearing axle 132, along the radial displacement of bearing axle 132 under the guide effect of first inclined plane L1, and then drive stopper 1371 along the radial displacement of bearing axle 132, realize that stopper 1371 moves between backstop position and material loading position promptly.

The stop driver 1372 is mounted on the bearing seat 131 or the bearing shaft 132 and is drivingly connected to the second wedge block 1373 to drive the second wedge block 1373 to move along the axial direction of the bearing shaft 132, so as to move the stop block 1371 between the stop position and the loading position. In this way, by the sliding fit between the second wedge block 1373 and the first inclined surface L1 of the first wedge block 1374, the axial movement of the second wedge block 1373 along the bearing shaft 132 is converted into the radial movement of the stop block 1371 along the bearing shaft 132, the structure is simple, and the stop block 1371 is stably and reliably switched between the stop position and the loading position. Alternatively, the stop driver 1372 may employ a cylinder.

Further, the stopping structure further includes a transmission rod 1377 (see fig. 17), one end of the transmission rod 1377 is connected to the second wedge block 1373, and the other end of the transmission rod 1377 extends to one end of the bearing shaft 132 near the bearing seat 131 and is connected to the driving end of the stopping driving member 1372. In this way, the linear movement output by the stop drive 1372 in the axial direction of the support shaft 132 is transmitted to the second wedge 1373 by means of the transmission rod 1377. Optionally, the bearing shaft 132 is provided with a receiving groove extending along the axial direction thereof, and the receiving groove is used for receiving the transmission rod 1377 so as to prevent the transmission rod 1377 from interfering with the stock roll A2 on the bearing shaft 132.

Further, second wedge 1373 has the second inclined plane L2 parallel with first inclined plane L1, and this first inclined plane L1 and second inclined plane L2 laminate mutually for the removal of second wedge 1373 relative first wedge 1374 is more smooth and easy, and reliable and stable.

Further, the second wedge block 1373 further has an abutment plane for abutment with the stop block 1371, the abutment plane is located at a side of the second wedge block 1373 facing away from the second inclined plane L2 and is parallel to the axial direction of the bearing shaft 132.

Specifically, in the embodiment, the stopping structure further includes a stop block 1375 and an elastic member 1376. The stop block 1375 is mounted in the mounting slot 1321 and is in sliding fit with the stop block 1371 and is in limit abutment with the stop block 1371 when the stop block 1371 moves to the stop position to prevent the stop block 1371 from continuing to move out of the mounting slot 1321. The elastic member 1376 is connected to the stopper 1371 and the stopper 1375 to provide a pre-load force that causes the stopper 1371 to have a tendency to move toward the loading position.

As shown in fig. 17 and 19, when the stop driving member 1372 drives the second wedge block 1373 to move rightwards, the second wedge block 1373 moves along the ascending direction of the first inclined surface L1 of the first wedge block 1374, so as to drive the stop block 1371 to move from the loading position to the stop position, and the stop block 1371 protrudes out of the circumferential side surface of the bearing shaft 132. When the stop driving member 1372 drives the second wedge block 1373 to move leftward, the second wedge block 1373 moves in a downward slope direction of the first inclined surface L1 of the first wedge block 1374, so that the stop block 1371 moves into the mounting groove 1321 under the action of the elastic member 1376 until completely entering the mounting groove 1321 (i.e., reaching the loading position). Alternatively, the elastic member 1376 may employ a torsion spring.

Referring to fig. 16 to 17, in some embodiments, each unwinding mechanism 11 further includes a deviation rectifying assembly 12, and the deviation rectifying assembly 12 includes a deviation rectifying base plate 121 and a deviation rectifying driving member 122. The carrying seat 131 of the unwinding assembly 13 is movably connected to the deviation rectifying bottom plate 121 along the axial direction of the carrying shaft 132, and the carrying seat 131 can drive the carrying shaft 132 and the unwinding shaft to move together along the axial direction. The deviation rectifying driving element 122 is disposed on the deviation rectifying bottom plate 121 and is in driving connection with the bearing seat 131 to drive the bearing seat 131 to move along the axial direction of the unreeling shaft, and then the bearing seat 131 drives the unreeling shaft and the working material roll A1 on the unreeling section 1332 of the unreeling shaft to move along the axial direction together, i.e. the deviation rectification of the working material tape B1 is realized. Alternatively, the offset drive 122 may be a linear module or the like.

Further, a guiding structure of a slide rail and a slider may be disposed between the deviation rectifying bottom plate 121 and the carrying seat 131, so that the guiding structure of the slide rail and the slider is utilized to guide the movement of the carrying seat 131 relative to the deviation rectifying bottom plate 121.

In some embodiments, the kick-off assembly 14 includes a kick-off drive assembly 141 and a kick-off fork 142 mounted at the drive end of the kick-off drive assembly 141, the kick-off fork 142 having a kick-off end extending to the carrier shaft 132. The material shifting driving assembly 141 is configured to drive the material shifting fork 142 to move along the axial direction of the carrying shaft 132, so as to shift the stock roll A2 on the carrying shaft 132 to the unwinding section 1332 by using the material shifting end until the front stock roll A2 moves to the unwinding section 1332. Further, the shape of the kick-out end matches the shape of the peripheral side surface of the bearing shaft 132 to facilitate better kick-out of the reserve roll A2. Alternatively, the material ejecting driving assembly 141 may adopt a linear module or the like.

Referring to fig. 16 and 20, in an embodiment of the present invention, the automatic roll changing apparatus further includes a guiding device 40 for guiding the work material tape B1 outputted by any one of the two unwinding mechanisms 11. The unwinding assembly 13 of each unwinding mechanism 11 further includes a connection driving block 15 connected to the carrying base 131 or the carrying shaft 132. For convenience of description, the unwinding assemblies 13 of the two unwinding mechanisms 11 are respectively named as a first unwinding assembly 13a and a second unwinding assembly 13b.

The guide device 40 includes a fixed base 42, a guide frame 44, and a switching mechanism 45. The guide frame 44 is movably coupled to the fixing base 42 in a direction parallel to an axial direction of the unwinding shaft of the unwinding assembly 13. The guide frame 44 is provided with a guide roller 41 around which the work material tape B1 is passed. The switching mechanism 45 is connected to the guide frame 44, and may be selectively connected to one of the connection driving block 15 of the first unwinding assembly 13a or the connection driving block 15 of the second unwinding assembly 13b.

When the material roll on the first unwinding assembly 13a is the working material roll A1, the material roll on the second unwinding assembly 13b is the standby material roll A2, and the first unwinding assembly 13 performs deviation rectification, the guiding device 40 firstly controls the switching mechanism 45 to be connected with the connection driving block 15 of the first unwinding assembly 13a, so that the first unwinding assembly 13a performs deviation rectification movement along the axial direction of the unwinding shaft under the driving of the deviation rectification assembly 12, and simultaneously drives the guiding frame 44 and the guiding roller 41 on the guiding frame 44 to perform synchronous deviation rectification movement.

When the material roll on the second unwinding assembly 13b is the working material roll A1, the material roll on the first unwinding assembly 13a is the standby material roll A2, and the second unwinding assembly 13b performs deviation rectification, the switching mechanism 45 is first controlled to be connected to the connection driving block 15 of the second unwinding assembly 13b, so that the second unwinding assembly 13b performs deviation rectification movement along the axial direction of the unwinding shaft under the driving of the deviation rectification assembly 12, and simultaneously drives the guide frame 44 and the guide roll 41 on the guide frame 44 to perform synchronous deviation rectification movement. Therefore, in the embodiment, the switching mechanism 45 is selectively connected with one of the connection driving blocks 15 of the two unwinding assemblies 13, so that the deviation rectification consistency of the guide roller 41 and the unwinding shaft for loading the working material roll A1 is good, the deviation rectification effect is improved, and the product quality is ensured.

In some embodiments, the switching mechanism 45 includes a first clasping assembly 451 and a second clasping assembly 452 mounted to the guide frame 44. The first clasping assembly 451 may be connected to or separated from the connection driving block 15 of one unwinding assembly 13, and the second clasping assembly 452 may be connected to or separated from the connection driving block 15 of another unwinding assembly 13. For example, the first clasping assembly 451 may be coupled to or separated from the coupling driving block 15 of the first unwinding assembly 13 a. The second clasping assembly 452 can be connected with or separated from the connecting driving block 15 of the second unwinding assembly 13b. Thus, when the material roll on the first unwinding assembly 13a is the work material roll A1, the first clasping assembly 451 is connected to the connection driving block 15 of the first unwinding assembly 13a, and the second clasping assembly 452 is separated from the connection driving block 15 of the second unwinding assembly 13b, so that the guide roller 41 and the first unwinding assembly 13a perform deviation rectifying motion synchronously. When the material roll on the second unwinding assembly 13b is the work material roll A1, the first clasping assembly 451 is separated from the connection driving block 15 of the first unwinding assembly 13a, and the second clasping assembly 452 is connected with the connection driving block 15 of the second unwinding assembly 13b, so that the guide roller 41 and the second unwinding assembly 13b synchronously perform deviation rectifying movement.

In particular embodiments, the first hugging assembly 451 comprises two first hugging blocks 4511 and a first hugging drive 4512. Two first hug blocks 4511 are arranged opposite each other on the guide frame 44. The first hugging driving member 4512 is in transmission connection with two first hugging blocks 4511. Under the driving of the first clasping driving member 4512, at least one of the two first clasping blocks 4511 moves closer to or away from the other to clamp or release the connecting driving block 15 of the corresponding unreeling assembly 13.

Further, a first connecting block 4513 is connected to each of the two first hugging blocks 4511. The first hugging drive member 4512 has a first fixed end and a first telescopic end which is telescopic relative to the first fixed end. This first stiff end and first flexible end are connected with two first connecting blocks 4513 respectively to drive two first blocks 4511 of holding tightly through the flexible of the relative first stiff end of first flexible end and press from both sides tightly or loosen and correspond the connection drive block 15 who unreels subassembly 13. Alternatively, the first hugging drive 4512 may be an air cylinder.

Further, be provided with first slide rail on the leading truck 44, all be provided with on two first blocks 4511 of hugging closely with first slide rail sliding fit's first slider. In this way, the two first sliding blocks slide along the first sliding rails respectively to guide the movement of the two first hugging blocks 4511 toward or away from each other relative to the guide frame 44.

In one embodiment, the second clasping assembly 452 comprises two second clasping blocks 4521 and a second clasping driving member 4522. Two second hug blocks 4521 are arranged opposite each other on the guide frame 44. The second hugging driving member 4522 is in transmission connection with two second hugging blocks 4521. Under the driving of the second clasping driving member 4522, at least one of the two second clasping blocks 4521 moves closer to or away from the other to clamp or release the connecting driving block 15 of the corresponding unreeling assembly 13.

Further, a second connecting block 4523 is connected to each of the two second hugging blocks 4521. The second hugging drive member 4522 has a second fixed end and a second telescoping end that is telescoping relative to the second fixed end. The second fixed end and the second telescopic end are respectively connected with the two second connecting blocks 4523, so that the two second clasping blocks 4521 are driven to clamp or loosen the connecting driving block 15 corresponding to the unreeling component 13 through the extension and retraction of the second telescopic end relative to the second fixed end. Alternatively, the second hugging drive 4522 may be an air cylinder.

Further, a second slide rail is arranged on the guide frame 44, and second slide blocks in sliding fit with the second slide rail are arranged on the two second enclasping blocks 4521. In this way, the two second sliding blocks respectively slide along the second sliding rails to guide the movement of the two second hugging blocks 4521 toward or away from each other with respect to the guide frame 44.

In some embodiments, the guide frame 44 includes a first guide post 441, a guide roller seat 43, and a moving seat 442. The first guide post 441 is slidably engaged with the fixed seat 42, and the guide roller seat 43 is connected to one end of the first guide post 441, so that the guide roller seat 43 can move together with the first guide post 441 relative to the fixed seat 42. The guide roller 41 is mounted on the guide roller holder 43 so as to be movable together with the guide roller holder 43. The moving base 442 is coupled to the other end of the first guide post 441, and the switching mechanism 45 is mounted on the moving base 442. Thus, when the switching mechanism 45 is connected to one of the connection driving blocks 15 of the unwinding assembly 13, and the unwinding assembly 13 performs deviation rectifying motion, the switching mechanism 45 drives the moving seat 442 to move synchronously, and then the moving seat 442 drives the guide roller 41 to move synchronously through the first guide post 441 and the guide roller seat 43, so as to ensure that the guide roller 41 and the unwinding shaft of the unwinding assembly 13 perform deviation rectifying synchronously.

In an embodiment, the guiding frame 44 further includes a second guiding post 443 slidably engaged with the moving seat 442, and one end of the second guiding post 443 is connected to the fixed seat 42. In this way, the movement of the moving base 442 and the guide roller base 43 is guided by the first guide post 441 and the second guide post 443 together.

In particular, in the embodiment, the guide device 40 further includes a locking assembly 46 disposed on the moving seat 442, and the locking assembly 46 is configured to be coupled to or separated from the second guide post 443. In this way, when the automatic reel change is required, the locking assembly 46 is connected to the second guide post 443 so that the movable seat 442 cannot move relative to the fixed seat 42, thereby locking the position of the guide roller 41 and ensuring that the work material tape B1 wound around the guide roller 41 does not move, thereby ensuring that the backup material tape B2 of the backup roll A2 is aligned with the work material tape B1 when the automatic reel change is performed. When the deviation correction is required, the locking assembly 46 is separated from the second guide post 443, so that the moving seat 442 can perform a synchronous deviation correction movement along with the unwinding assembly 13.

Optionally, the locking assembly 46 includes a locking driving member mounted on the movable seat 442 and a holding claw mounted on a driving end of the locking driving member for driving the holding claw to hold or release the second guide post 443. Thus, when the locking driving member drives the locking claw to lock the second guide post 443, the movable base 442 cannot move relative to the fixed base 42, i.e., the position of the guide roller 41 is locked. When the locking driving member drives the clasping claw to release the second guide post 443, the movable base 442 can move relative to the fixed base 42, so that the guide roller 41 can perform a synchronous deviation rectifying motion with any unreeling assembly 13 through the switching mechanism 45. Alternatively, the locking drive may be a jaw cylinder.

The automatic roll changing process of the automatic roll changing device of the present invention is described below with reference to fig. 3 to 7:

initially, the material roll on the first unwinding mechanism 11a is the work material roll A1, and the work material tape B1 unwound and output is transported downstream by the guide roller 41. The material roll on the second unwinding mechanism 11b is a standby material roll A2. The first abutting portion 310 and the second abutting portion 311 of the first splicing mechanism 31a commonly attract the tape C, and the first abutting portion 310 and the second abutting portion 311 of the second splicing mechanism 31b do not attract the tape C.

When the unwinding of the work material roll A1 on the first unwinding mechanism 11a is completed, automatic roll change is required. First, the picking mechanism 22 swings clockwise along with the first swing arm 231 until the first clamping member 2221 and the second clamping member 2223 both abut against the stock roll A2 on the second unwinding mechanism 11B, and the material feeding head end B21 of the stock roll A2 is located between the first clamping member 2221 and the second clamping member 2223.

Then, the two blowing surfaces g2 of the second clamping member 2223 blow air, so that the two corner portions B211 of the leading end B21 of the tape are respectively blown up onto the two second suction surfaces g1 of the first clamping member 2221, and are sucked and fixed by the two second suction surfaces g 1. The second clamping member 2223 is controlled to move towards the first clamping member 2221 until the two corner portions B211 of the tape-starting end B21 are clamped together with the first clamping member 2221.

Then, the picking mechanism 22 swings counterclockwise along with the first swing arm 231 until the first clamping member 2221 and the second clamping member 2223 drive the tape-raising end B21 to pass through between the avoiding position and the splicing position (i.e., pass through above the supporting mechanism 21). The support mechanism 21 is moved upward to the splicing position so that the backup tape B2 is wound around the second support roller 213 of the support mechanism 21.

Then, the first splicing mechanism 31a swings clockwise to the splicing position following the second swing arm 322, so that the abutment roller 313 of the first splicing mechanism 31a abuts the backup tape B2 against the first support roller 212. The second clamping member 2223 is controlled to move away from the first clamping member 2221, so that the head end B21 of the tape is released. The second unwinding mechanism 11B drives the standby material roll A2 to rotate clockwise, so that the standby material tape B2 is gradually wound on the standby material roll A2 until the material start end B21 is adsorbed on the first adsorption surface 2101 on the left side of the support block 210. In the process of winding the spare tape B2, the two first absorbing surfaces 2101 on the left side and the right side of the supporting block 210 respectively absorb the passing spare tape B2, so that the tape starting end B21 is prevented from swinging arbitrarily.

Then, the first abutting portion 310 and the second abutting portion 311 of the first splicing mechanism 31a move leftward until the first abutting portion 310 presses the adhesive tape C and the spare tape B2 against the first absorbing surface 2101 on the right side of the supporting block 210, so that the right side of the spare tape B2 is adhered to the lower half of the adhesive tape C.

Then, the second tape splicing mechanism 31B swings counterclockwise to the tape splicing position following the second swing arm 322, so that the abutment roller 313 of the second tape splicing mechanism 31B presses the work material tape B1 against the first support roller 212. The first abutting portion 310 and the second abutting portion 311 of the second tape splicing mechanism 31B are controlled to move rightward until the first abutting portion 310 presses the working tape B1 and the tape-up end B21 against the first suction surface 2101 on the left side of the support block 210. The cutting section 312 that controls the second splicing mechanism 31B cuts the work tape B1 between the abutment roller 313 and the first abutment portion 310. Then, the second abutting portion 311 of the second splicing mechanism 31B is controlled to move rightward until the second abutting portion 311 presses the working tape B1 against the adhesive tape C of the second abutting portion 311 of the first splicing mechanism 31a, so that the working tape B1 is bonded to the upper half portion of the adhesive tape C. At this time, the right sides of the working material belt B1 and the spare material belt B2 are both bonded with the adhesive tape C, and then the splicing is completed.

Then, the first tape splicing mechanism 31a swings counterclockwise to the glue preparation position along with the second swing arm 322, the second tape splicing mechanism 31b swings clockwise to the glue preparation position along with the second swing arm 322, and the support mechanism 21 moves downward to the avoiding position. The standby material roll A2 on the second unwinding mechanism 11B is switched to the work material roll A1, and the second unwinding mechanism 11B drives the work material roll A1 thereon to rotate counterclockwise, thereby conveying the work material strip B1 downstream.

After the work material tape B1 is cut, the empty cartridge A3 on the first unwinding mechanism 11a can be conveyed to the take-up shaft 341 of the cartridge collecting mechanism 34 by the cartridge conveying mechanism 35. When the second splicing mechanism 31b swings to the glue preparation position, the glue preparation mechanism 33 can be used to prepare the first abutting portion 310 and the second abutting portion 311 of the second splicing mechanism 31b for the next automatic roll change.

The handling of the empty barrel A3 and the glue preparing process of the butt-joint belt mechanism 31 are described in the foregoing, and are not described herein again.
