The specific structure of the automatic splicing apparatus 200 according to the present invention will be described below by way of example.

Please continue to refer to fig. 2 to 4. In some embodiments, the automated taping device includes a first gripper assembly 210, a cutter assembly 220, a second gripper assembly 230, and a carrier assembly 240.

The first grabbing component 210 can grab the work tape 11, and the work tape 11 is a tape currently used for sticking products.

The cutting unit 220 can cut the work material tape 11 on the upstream side of the first gripper unit 210 after the first gripper unit 210 has gripped the work material tape 11. The upstream side and the downstream side in this description are based on the conveying path of the work tape 11. The cutting assembly 220 cuts the work material tape 11 at a position between the roll of work material tape 11 and the first gripper assembly 210. The cutting assembly 220 is provided to separate the work material tape 11 from the rest of the material tape on the tray. In other embodiments, the cutting assembly 220 may not be provided. For example, after the work material tape 11 is separated from the tray for winding the work material tape 11, the first grabbing component 210 grabs the tail end of the work material tape 11.

The second gripper assembly 230 is capable of gripping the supply of tape 12. The reserve tape 12 can take over the roll of work material for application of the product when the strip of work material 11 is about to run out. In popular terms, the spare material belt 12 is a new working material belt 11.

The carrying assembly 240 is capable of carrying the second grabbing assembly 230 from the first predetermined position P1 to the second predetermined position P2. The first predetermined position P1 corresponds to an unwinding device for unwinding the backup tape 12, and the second predetermined position P2 is located at the downstream side of the first gripper assembly 210. The tape 12 can be driven to extend from the first predetermined position P1 to the second predetermined position P2, so as to allow the head end of the tape 12 to be attached to the work tape 11. As the name implies, the upstream side and the downstream side are opposite concepts, and in the present embodiment, the upstream side and the downstream side of the first gripper unit 210 correspond to two sides of the first gripper unit 210 along the conveying path of the work tape 11.

As shown in fig. 4, the second gripper assembly 230 is capable of gripping the leading end of the spare tape 12 at a first predetermined position P1. The second grabbing element 230 can be moved from the first predetermined position P1 to the second predetermined position P2 by the carrying element 240 (shown in fig. 3). The second grabbing assembly 230 can press at least a portion of the head end of the spare tape 12 against the work tape 11 at the second predetermined position P2, so that the spare tape 12 is attached to the work tape 11, and automatic splicing is realized. This is done. The embodiment can simplify the steps of automatic tape splicing, simplify the structure of the automatic tape splicing device, reduce the occupied space of the automatic tape splicing device, further simplify the structure of the adhesive tape sticking equipment and reduce the occupied space of the adhesive tape sticking equipment.

Referring to fig. 4 to 7, fig. 5 is a schematic front view of the adhesive applying apparatus shown in fig. 1, and fig. 6 is a schematic side view of the adhesive applying apparatus shown in fig. 1.

In some embodiments, the second grasping assembly 230 includes a first jaw 231, a second jaw 232, a first drive 233, and a second drive 234.

As the name implies, the first jaw 231 and the second jaw 232 can perform a clamping function. Specifically, the first jaw 231 and the second jaw 232 may cooperate with each other to grip the reserve tape 12. For example, the first jaw 231 and the second jaw 232 may be drawn toward each other.

The first driving member 233 can drive the first clamping jaw 231 and the second clamping jaw 232 to close together to clamp the head end of the spare tape 12. When the carrying assembly 240 drives the second grabbing assembly 230 to move to the second predetermined position P2, the first and

second jaws

231 and 232 drive the spare tape 12 to extend toward the work tape 11.

Optionally, the first drive member 233 is a jaw cylinder. The moving ends of the clamping jaw cylinder are respectively connected to the first clamping jaw 231 and the second clamping jaw 232.

Further, when the first clamping jaw 231 and the second clamping jaw 232 clamp the reserve tape 12, in order to facilitate the reserve tape 12 to be reliably clamped between the first clamping jaw 231 and the second clamping jaw 232, the second driving member 234 can drive the first clamping jaw 231 and the second clamping jaw 232 to rotate, so that the head end of the reserve tape 12 is wrapped outside the first clamping jaw 231 and/or the second clamping jaw 232. Therefore, the present embodiment can reduce the risk that the spare tape 12 is separated from the second grabbing assembly 230, and can also facilitate the application of the spare tape 12 to the working tape 11.

Optionally, the second driver 234 is a rotary cylinder. The first clamping jaw 231 and the second clamping jaw 232 are disposed at the rotating end of the second driving member 234. When the first clamping jaw 231 and the second clamping jaw 232 clamp the reserve tape 12, the second driving member 234 drives the head end of the reserve tape 12 to rotate by a predetermined angle, so as to wind the reserve tape 12 around the first clamping jaw 231 and/or the second clamping jaw 232. For example, the preset angle may be 200 °, 250 °, 270 °, and the like, which is not limited herein.

The adhesive surface of the backup tape 12 faces away from the first jaw 231 and/or the second jaw 232. When the carrying assembly 240 drives the first clamping jaw 231 and the second clamping jaw 232 to move to the second predetermined position P2, the head end of the standby tape 12 can be pressed against the work tape 11 without separately performing a pressing action.

In the above embodiment, since the head end of the spare tape 12 wraps around the first jaw 231 and/or the second jaw 232, when the second gripper assembly 230 is located at the second predetermined position P2, only a portion of the outer peripheral wall of the first jaw 231 and/or the second jaw 232 interferes with the work tape 11, so that only a portion of the head end of the spare tape 12 can be pressed against the work tape 11.

In some embodiments, the second gripper assembly 230 may also vacuum grip the head end of the spare tape 12. In this embodiment, when the second gripper assembly 230 is located at the second predetermined position P2, the entire head end of the spare tape 12 can be pressed against the working tape 11.

Please continue to refer to fig. 3 and 5. In some embodiments, the handling assembly 240 includes a swing arm 241 and a third drive 242.

The swing arm 241 is capable of swinging, and the second grasping assembly 230 is provided on the swing arm 241. Therefore, under the driving of the swing arm 241, the second grabbing element 230 can swing the first predetermined position P1 or the second predetermined position P2 selectively.

The third driving element 242 can drive the swing arm 241 to swing by a predetermined angle. The predetermined angle is the angle of the swing arm 241 driving the second grabbing element 230 to swing from the first predetermined position P1 to the second predetermined position P2, or the angle of the swing arm 241 driving the second grabbing element 230 to swing from the second predetermined position P2 to the first predetermined position P1. In other words, the third driving element 242 drives the swing arm 241 to swing by a predetermined angle, so as to drive the second grabbing assembly 230 to swing between the first predetermined position P1 and the second predetermined position P2. The preset angle may be 180 °, which is not limited herein.

Specifically, the third driving element 242 drives the swing arm 241 to swing by a predetermined angle, and drives the second grabbing assembly 230 connected to the swing arm 241 to swing to the first predetermined position P1, where the second grabbing assembly 230 can grab the head end of the spare tape 12 at the first predetermined position P1. The third driving element 242 drives the swing arm 241 to swing by a predetermined angle, so as to drive the second grabbing assembly 230 to clamp the head end of the spare tape 12 and swing to a second predetermined position P2, so as to press the head end of the spare tape 12 against the work tape 11.

In the above embodiment, the carrying assembly 240 drives the second grabbing assembly 230 to rotate along a curved path, and in other embodiments, the carrying assembly 240 may also drive the second grabbing assembly 230 to move along other paths, which is not limited herein.

Referring to fig. 3, 4, 5 and 8, fig. 8 is a schematic side view of the automatic belt splicing apparatus shown in fig. 7. In some embodiments, to facilitate the secure attachment of the leading end of the backup tape 12 to the work tape 11, the splicing device further comprises a stop 251.

The stop member 251 is disposed at the downstream side of the first grabbing assembly 210 and is located at one side of the work material tape 11. When the second grabbing assembly 230 is located at the second predetermined position P2, the second grabbing assembly 230 presses at least a portion of the head end of the spare tape 12 and the working tape 11 against the stop 251 from the other side of the working tape 11.

Further, the automatic belt splicing apparatus further includes a pressing member 252 and a fourth driving member 253.

The pressing element 252 is disposed on the downstream side of the first grabbing component 210 and is located on the other side of the work tape 11. The fourth driving member 253 is used for driving the abutting member 251 to approach the abutting member 252 so as to press at least a part of the head end of the spare tape 12 and the working tape 11 against the abutting member 251. In some embodiments, after the second grabbing assembly 230 releases the spare tape 12, the fourth driving member 253 drives the abutting member 251 to approach the abutting member 252, so as to press the leading end of the spare tape 12 and the working tape 11 against the abutting member 251. The pressure from both sides is applied to the bonding position of the working tape 11 and the standby tape 12, which is beneficial to ensure that the standby tape 12 and the working tape 11 are firmly bonded. In other words, when the second grabbing assembly 230 clamps the head end of the backup tape 12 and moves to the second predetermined position P2, the outer surface of the backup tape 12 has adhesiveness and can be attached to the work tape 11, and the backup tape 12 and the work tape 11 can be further firmly attached by pressing the attachment portion of the backup tape 12 and the work tape 11 by the abutting member 251 and the abutting member 252, so that the risk of separation of the backup tape 12 and the work tape 11 during the moving process is reduced, and the reliability of automatic tape splicing is improved.

Optionally, in this embodiment, after the second grabbing element 230 is reset (located at the first predetermined position P1), the pressing element 252 is close to the abutting element 251, so as to reduce the risk of interference between the second grabbing element 230 and the abutting element 251 and the pressing element 252.

Please continue to refer to fig. 3 and 4. In some embodiments, the automated taping device also includes a guide 254.

The guide 254 is disposed at the downstream side of the first grabbing assembly 210, and the work tape 11 is wound around the guide 254, so that the work tape 11 changes the conveying direction at the guide 254. The work material tape 11 is movable relative to the guide 254.

Wherein the second predetermined position P2 is located on the downstream side of the guide 254. After the spare tape 12 is connected with the working tape 11, in the continuous conveying process of the working tape 11, the guide 254 can give the force towards the spare tape 12 to the tail end of the working tape 11, so as to promote the tail end of the working tape 11 to be completely adhered to the spare tape 12, and ensure that the adhered part of the working tape 11 and the spare tape 12 is smooth.

Further, the guide 254 may be a guide roller, and the guide 254 may be capable of rotating. For example, the guide roller may rotate about its axis. Therefore, when the automatic tape splicing device conveys the work tape 11, the guide 254 can rotate with the movement of the work tape 11, and the resistance when the work tape 11 moves with respect to the guide 254 is reduced.

Referring to fig. 3, 4, 7 and 8, fig. 7 is a schematic front view structure diagram of an embodiment of the automatic tape splicing device for cutting a work tape, and fig. 8 is a schematic side view structure diagram of the automatic tape splicing device shown in fig. 7. The following description will be given by way of example of the specific structure of the first gripper assembly 210 of the present application.

In some embodiments, the first grasping assembly 210 includes a third jaw 211, a fourth jaw 212, a fifth drive 213, and an eleventh drive 214.

The third jaw 211 and the fourth jaw 212 are capable of performing a gripping function, similar to the first jaw 231 and the second jaw 232 described previously.

In particular, it may be that the third and

fourth jaws

211, 212 cooperate to grip the strip of work material 11. For example, the third jaw 211 and the fourth jaw 212 may be drawn toward each other.

In practical use, because the outer diameter of the material roll of the working material tape 11 is smaller, an included angle can be formed between the tail end of the working material tape 11 and the standby material tape 12, so that the risk that the tail end of the working material tape 11 is stuck on the standby material tape 12 is reduced.

The fifth driving member 213 can drive the third jaw 211 and the fourth jaw 212 to close together to clamp the work tape 11. Wherein the guide 254 is provided on the downstream side of the third and

fourth jaws

211, 212.

Optionally, the fifth driver 213 is a jaw cylinder. The moving ends of the air cylinder are connected to the third clamping jaw 211 and the fourth clamping jaw 212, respectively.

The fifth driving member 213 is disposed at the moving end of the eleventh driving member 214. The eleventh driving member 214 is used for driving the fifth driving member 213 to move vertically. The eleventh driver 214 may be a cylinder. When the automatic tape splicing device splices a tape, the second driving member 234 drives the fifth driving member 213 to ascend, and the fifth driving member 213 drives the third clamping jaw 211 and the fourth clamping jaw 212 to clamp the work tape 11. Under the state that the automatic tape splicing device normally unreels the work material tape 11, the second driving member 234 drives the fifth driving member 213 to be away from the work material tape 11 in the vertical direction, so as to avoid the interference of the third clamping jaw 211 and the fourth clamping jaw 212 on the work material tape 11.

Please continue to refer to fig. 7. In some embodiments, the cutting assembly 220 includes a cutting member 221 and a sixth drive member 222.

The cutting member 221 is disposed on the sixth driving member 222. When the work tape 11 needs to be cut, the sixth driving element 222 drives the cutting element 221 to move toward the work tape 11, so as to cut the work tape 11.

The cutting member 221 may be a scissors, a cutter, etc., and the sixth driving member 222 may be an air cylinder, which is not limited herein.

Referring to fig. 4, fig. 5 and fig. 9 in combination, fig. 9 is a schematic front view of an unwinding device according to an embodiment of the present application. The following describes a specific structure of the unwinding device of the present application by way of example.

In some embodiments, the unwinding device includes a third grabbing assembly 310, an expansion shaft 320, a carrying platform 330, and a pushing member 341. The roll is hereinafter a roll of the working tape 11 or the spare tape 12.

The third grasping element 310 is used to grasp or release the roll. In particular, the third grabbing component 310 is able to grab a roll of the spare strip of material 12, and the third grabbing component 310 is also able to release the roll of the spare strip of material 12, which becomes the new roll of work strip 11.

In some embodiments, the third grasping element 310 includes at least one pair of stoppers 311.

The pair of limiting members 311 are disposed at an interval, and the pair of limiting members 311 form a gap to receive the head end of the material roll. The gap extends in the axial direction of the expansion shaft 320. In combination with the automatic belt splicing apparatus described in the above embodiments, a pair of stoppers 311 are further disposed opposite to the first clamping jaw 231 and the second clamping jaw 232. Specifically, when the second gripper assembly 230 is located at the first predetermined position P1, the second gripper assembly 230 is disposed corresponding to the gap in the axial direction of the expansion shaft 320. In one application scenario, the second gripper assembly 230 is located directly below the gap, and during the descent of the roll with the takeup shaft 320, the leading end of the roll enters the gripping range of the second gripper assembly 230.

Further, the third grabbing assembly 310 further comprises a clamping block 312 and a seventh driving element 313.

The number of the clamping blocks 312 is at least two, and the two clamping blocks 312 can move close to or away from each other to clamp or release the material roll.

The seventh driving members 313 correspond to the clamping blocks 312 one to one. Each seventh driving member 313 is used for driving the corresponding clamping block 312 to move, so that the two clamping blocks 312 move close to or away from each other. The seventh driver 313 may be a cylinder.

The expansion shaft 320 is movable in its axial direction to approach or move away from the third gripper assembly 310. During the approach of the expansion spool 320 to the third gripper assembly 310, the expansion spool 320 can be inserted into the roll on the third gripper assembly 310. When the expansion shaft 320 inserts the roll, the seventh driving member 313 drives the clamping blocks 312 away from each other to release the roll, leaving the roll in the expansion shaft 320. The expansion shaft 320 is capable of changing the radial dimension to hold or release the roll of material placed over it, for example, the expansion shaft 320 may be vented with compressed air to effect the change in the radial dimension. The takeup shaft 320 is also capable of spinning to unwind the tape held thereon.

In some embodiments, the unwinding device further includes an eighth driving unit 321, and the eighth driving unit 321 is used for driving the expansion shaft 320 to move to insert the material roll. Alternatively, the eighth driver 321 may be a cylinder.

Specifically, the expansion shaft 320 can increase its radial dimension to hold the roll after it is inserted into the roll. When the automatic splicing device unreels the work material belt 11 to paste a product, the expansion shaft 320 can rotate at a speed suitable for unreeling the work material belt 11 to unreel a material roll fixed on the expansion shaft, so that resistance when the work material belt 11 is unreeled can be reduced, and a risk of winding the work material belt 11 can be reduced. The expansion shaft 320 reduces its radial dimension to allow release of the roll of the backup tape 12 when it is desired to replace the roll of the current work tape 11 with a roll of the backup tape.

The bearing table 330 is sleeved outside the expansion shaft 320. During the axial movement of the material roll with respect to the expansion shaft 320 along the expansion shaft 320, the material roll is separated from the expansion shaft 320, and the carrier 330 can carry the material roll released from the expansion shaft 320.

Specifically, the carrier 330 may be stationary, and the expansion shaft 320 may move relative to the carrier 330; or, the expansion shaft 320 may be stationary, and the plummer 330 may move relative to the expansion shaft 320, so as to reduce the moving range in the vertical direction of the drawing, which is beneficial to improving the compactness of the unwinding device.

The pusher 341 can be moved relative to the carrier 330 to push the roll off the carrier 330 and discard the used roll.

The unwinding device may further include a ninth driving member 342. The ninth driving member 342 can drive the pushing member 341 to move. Alternatively, the ninth driver 342 may be a cylinder.

Referring to fig. 9 to 12, fig. 10 is a schematic side view of the unwinding device shown in fig. 9, fig. 11 is a schematic top view of the unwinding device shown in fig. 9, and fig. 12 is a schematic cross-sectional view of the unwinding device shown in fig. 11 along a direction a-a.

In some embodiments, the carrier 330 may include a support 331, a carrier 332, and a tenth driving member 333.

The support 331 can accommodate the expansion shaft 320 therethrough.

The carrier 332 is disposed on the support 331, and the carrier 332 can carry the material roll held on the tightening shaft 320, so as to perform the functions of carrying and positioning, and limit the material roll from moving relative to the tightening shaft 320 due to the action of gravity. Optionally, the carrier 332 is rotatably disposed on the support 331, so that when the roll is unwound, the carrier 332 can rotate along with the rotation of the roll.

When the roll is exhausted, the cutting assembly 220 (shown in fig. 3) cuts the work material tape 11, the tenth driving member 333 drives the supporting member 331 to move in a direction of approaching the expanding shaft 320 along the axial direction thereof, so that the roll held on the expanding shaft 320 is transferred to the upper surface of the carrier 332 (shown in fig. 12), and the pushing member 341 moves relative to the carrier 330 to push away the roll on the carrier 330.

Further, the unwinding device further includes a collecting member 350. The collecting member 350 is disposed on a moving path of the material roll when the material pushing member 341 pushes the material roll, and can be used for receiving the material roll residue of the exhausted work material tape 11. When the pusher 341 pushes the roll on the carrier table 330 away from the carrier table 330, the roll can fall into the collector 350.

Still further, as shown in fig. 1, the unwinding device further includes a pressing member 360. Referring to fig. 1 and 5 in combination, the pressing member 360 can limit the movement of the material roll when the clamping block 312 clamps the material roll. And the pressing member 360 has elasticity to release the roll by an elastic restoring force, which will not be described herein.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
