Referring to fig. 1, 2 and 3, an embodiment of the present invention provides a mandrel loading apparatus, which includes a blanking station B1, an adjusting station B2, a gluing station B3 and a loading station (not shown). The mandrel feeding equipment comprises a transfer device 10, a blanking device 20, an adjusting device 30, a rubberizing device 40 and a feeding device 50.

The transfer device 10 is movable to the blanking station B1, the adjustment station B2, the rubberizing station B3 and the loading station. The blanking device 20 is disposed at the blanking station B1, and is used for storing and outputting the core rods a one by one. When the transfer device 10 moves to the blanking station B1, the mandrel a output from the blanking device 20 can be received. The adjusting device 30 is arranged at the adjusting station B2 and is used for driving the mandrel a transferred to the adjusting station B2 by the transfer device 10 to rotate until the positioning part a1 on the mandrel a is located at a preset position, so that the positioning part a1 on the mandrel a is matched with the winding needle of the winding mechanism D. The rubberizing device 40 is disposed at the rubberizing station B3, and is configured to attach the double-sided adhesive layer a2 to the mandrel a transferred to the rubberizing station B3 by the transfer device 10, so that the mandrel a can be adhered to a winding tape (which may be a diaphragm) by the double-sided adhesive layer a2 when being loaded onto a winding needle of the winding mechanism D, and the winding tape can be wound on the mandrel a when the winding needle drives the mandrel a to rotate. The feeding device 50 is arranged at the feeding station and is used for clamping the core rod A transferred to the feeding station by the transfer device 10 and transferring the clamped core rod A to the winding mechanism D, so that the winding needle of the winding mechanism D is inserted into the core rod A and is in positioning fit with the positioning part a1 of the core rod A. Alternatively, the positioning portion a1 may be a notch or a protrusion, etc. opened on the core rod a, and is used for positioning and matching with the winding needle, so that the winding needle can drive the core rod a thereon to rotate.

In the mandrel bar loading apparatus, a plurality of mandrel bars a are stored in the blanking device 20 during the actual loading operation, and the blanking device 20 outputs the mandrel bars a one by one. The transfer device 10 moves to the blanking station B1 to receive the core rod a output by the blanking device 20. Then, the transferring device 10 moves to the adjusting station B2 with the mandrel a, and at this time, the adjusting device 30 acts to drive the mandrel a to rotate until the positioning portion a1 on the mandrel a rotates to a preset position, so that the winding needle can match with the positioning portion a1 when the mandrel a is transferred to the winding mechanism D. Then, the transfer device 10 moves to the gluing station B3 with the adjusted mandrel a, and the gluing device 40 attaches the two-sided adhesive layer a2 to the mandrel a on the transfer device 10. Then, the transfer device 10 carries the mandrel a with the double-sided adhesive layer a2 attached thereon to move to the feeding station, at which time the feeding device 50 grips the mandrel a on the transfer device 10 and transfers the mandrel a to the winding mechanism D. Then, the winding needle of the winding mechanism D is inserted into the mandrel a, and is positioned and matched with the positioning portion a1 on the mandrel a. The loading device 50 then releases the core rod a and returns to the loading station, at which point the loading of one core rod a is completed. Therefore, the transfer of the core rod A among the blanking station B1, the adjusting station B2, the rubberizing station B3 and the feeding station is realized through the transfer device 10, and then the blanking, the adjustment, the rubberizing and the feeding of the core rod A are completed at each station in sequence by utilizing the blanking device 20, the adjusting device 30, the rubberizing device 40 and the feeding device 50, so that the automation degree is high, and the production efficiency is favorably improved.

It should be noted that the loading station is not required, and in other embodiments, the loading station may not be provided. That is, the transfer device 10 transfers the core rod a to the pasting station B3, and pasting is performed on the core rod a by the pasting device 40. Then, the feeding device 50 directly grips the core rod a located at the gumming station B3, and transfers the gripped core rod a onto the winding mechanism D.

In the specific embodiment, the mandrel feeding equipment further comprises a large installation plate 60, and the transfer device 10, the blanking device 20, the adjusting device 30, the rubberizing device 40 and the feeding device 50 are all installed on the large installation plate 60, so that the integration level of the equipment is improved, the maintenance is convenient, and the occupied space is reduced.

In the embodiment of the present invention, the transfer device 10 includes two transfer mechanisms 13, wherein one transfer mechanism 13 can move between the blanking station B1 and the adjusting station B2 to receive the mandrel a output by the blanking device 20 at the blanking station B1 and transfer the mandrel a to the adjusting device 30 at the adjusting station B2. The other transfer mechanism 13 is movable between the adjusting station B2 and the subsequent stations (i.e., the gluing station B3 and the loading station) to receive the core rod a transferred by the adjusting device 30 at the adjusting station B2, to apply glue to the core rod a by the gluing device 40 at the gluing station B3, and to transfer the core rod a to the loading device 50 at the loading station.

For convenience of description, the transfer mechanism 13 moving between the blanking station B1 and the setting station B2 is named a first transfer mechanism 13a, and the transfer mechanism 13 moving between the setting station B2, the taping station B3, and the loading station is named a second transfer mechanism 13B. In the actual loading operation, the first transfer mechanism 13a moves to the blanking station B1 and receives the mandrel a discharged from the blanking device 20. Then, the first transfer mechanism 13a moves to the adjusting station B2, so that the adjusting device 30 picks up the mandrel a on the first transfer mechanism 13a and drives the mandrel a to rotate until the positioning portion a1 on the mandrel a is located at the preset position. Meanwhile, the first transfer mechanism 13a returns from the adjustment station B2 to the blanking station B1 to receive the next core rod a output from the blanking device 20, and the second transfer mechanism 13B moves to the adjustment station B2. Then, the adjusting device 30 transfers the adjusted mandrel a to the second transfer mechanism 13B, and the second transfer mechanism 13B moves the adjusted mandrel a to the taping station B3 with it. Then, the taping device 40 applies the double-sided adhesive layer a2 to the core rod a on the second transfer mechanism 13b. Then, the second transfer mechanism 13b moves to the feeding station with the mandrel a subjected to the tape attaching, and the feeding device 50 grips the mandrel a on the second transfer mechanism 13b and transfers the mandrel a to the winding mechanism D. The second transfer mechanism 13b can now return to the adjustment station to receive the next adjusted mandrel a.

It can be understood that the process of transferring the core rod a between the blanking station B1 and the adjusting station B2 by the first transfer mechanism 13a and the process of transferring the core rod a between the adjusting station B2, the rubberizing station B3 and the loading station by the second transfer mechanism 13B can be performed simultaneously, so that the loading efficiency of the core rod a can be greatly improved.

Referring to fig. 4, in some embodiments, the transferring device 10 further includes a base 110, and a first transferring driving mechanism (not shown) and a second transferring driving mechanism (not shown) disposed on the base 110. The base 110 is fixedly mounted on the mounting plate 60. The first transfer mechanism 13a and the second transfer mechanism 13B are movably connected to the base 110 along the first direction X and are respectively in driving connection with the first transfer driving mechanism and the second transfer driving mechanism, so that the first transfer driving mechanism drives the first transfer mechanism 13a to move between the blanking station B1 and the adjusting station B2; the second transfer driving mechanism drives the second transfer mechanism 13B to move among the adjusting station B2, the rubberizing station B3 and the feeding station.

Alternatively, the first transfer driving mechanism comprises a driving cylinder 115, the driving cylinder 115 is mounted on the base 110, and the telescopic end of the driving cylinder 115 is connected with the first transfer mechanism 13a, so that the driving cylinder 115 is used for driving the first transfer mechanism 13a to move between the blanking station B1 and the adjusting station B2 along the first direction X. Of course, in other embodiments, the first transfer driving mechanism may also adopt other linear driving modules, as long as it can drive the first transfer mechanism 13a to move along the first direction X between the blanking station B1 and the adjusting station B2, and the invention is not limited thereto.

Optionally, the second transfer drive mechanism comprises a first lead screw 112, a transfer drive 111, and a first lead screw nut 113. The first lead screw 112 is rotatably connected to the base 110 around its axis, and the axial direction of the first lead screw 112 is parallel to the first direction X. The transfer driving unit 111 is mounted on the base 110 and is in driving connection with the first lead screw 112 to drive the first lead screw 112 to rotate around its axis. The first lead screw nut 113 is screwed onto the first lead screw 112 and fixedly connected to the second transfer mechanism 13b, so that the first lead screw nut 113 moves in the first direction X together with the second transfer mechanism 13b. In this way, when the transfer driving member 111 drives the first lead screw 112 to rotate, the first lead screw nut 113 moves along the axial direction (i.e. the first direction X) of the first lead screw 112, so as to drive the second transfer mechanism 13B to move along the first direction X among the adjusting station B2, the rubberizing station B3 and the feeding station. Alternatively, the transfer drive 111 may be a motor. Of course, in other embodiments, the second transfer driving mechanism may also adopt other linear driving modules, as long as it can drive the second transfer mechanism 13B to move along the first direction X between the adjusting station B2, the gluing station B3 and the feeding station, and the invention is not limited herein.

Referring to fig. 5 and fig. 6, in an embodiment of the present invention, the transferring mechanism 13 includes a mounting base 130, a supporting plate 132 and a clamping structure 136. The mount 130 is movably connected to the base 110 along the first direction X, and is connected to the first transfer driving mechanism or the second transfer driving mechanism to be driven by the first transfer driving mechanism or the second transfer driving mechanism to move along the first direction X. A pallet 132 is mounted on the mount 130 for receiving the core rod A. The clamping structure 136 is used to clamp or unclamp the core rod a carried on the pallet 132. Specifically, the clamping structure 136 includes two clamping blocks 131, and the two clamping blocks 131 are disposed on the mounting seat 130 and located at two sides of the supporting plate 132 in the first direction X (in the embodiment shown in fig. 6, the two clamping blocks 131 are located at the left and right sides of the supporting plate 132, respectively). The two clamping blocks 131 can be controlled to move toward and away from each other to clamp or unclamp the core rods a carried on the pallet 132. In this way, in the blanking station B1, the core rod a output from the blanking device 20 is blanked onto the pallet 132 of the first transfer mechanism 13a, and then the two clamping blocks 131 of the first transfer mechanism 13a are controlled to approach each other until the core rod a on the pallet 132 is clamped. At the adjusting station B2, the adjusting device 30 places the adjusted core rod a on the pallet 132 of the second transfer mechanism 13B, and then controls the two holding blocks 131 of the second transfer mechanism 13B to approach each other until the core rod a on the pallet 132 is clamped.

Alternatively, the number of the clamping structures 136 may be plural, and the plurality of clamping structures 136 are arranged at intervals along the second direction Y perpendicular to the first direction X. When the mandrel a is carried on the pallet 132, the longitudinal direction of the mandrel a is parallel to the second direction Y. Thus, the mandrel a is clamped simultaneously by the clamping structures 136 arranged at intervals along the longitudinal direction of the mandrel a, so that the mandrel a is clamped more stably. In the embodiment illustrated in fig. 6 in particular, the number of gripping structures 136 is two.

Optionally, the base 110 is provided with a first slide rail 114 (see fig. 4) extending lengthwise along the first direction X, and the mounting seats 130 of the two transfer mechanisms 13 are each provided with a first slide block (not shown). Each first slider is slidably engaged with the first slide rail 114, so that the movement of the two transfer mechanisms 13 along the first direction X is guided by the movement of the two first sliders along the first slide rail 114.

Referring to fig. 7 to 12, in the embodiment, the clamping structure 136 further includes a first elastic member 134 and a wedge block 138 both disposed on the mounting seat 130. The two clamping blocks 131 are respectively and correspondingly provided with a first elastic piece 134, and each first elastic piece 134 is abutted with the corresponding clamping block 131, so that pre-tightening force enabling the two clamping blocks 131 to have a movement trend close to each other is provided. Each clamping block 131 has an abutting portion 1314, and the wedge block 138 is disposed on the mounting seat 130 and has a first side surface 1380 and a second side surface 1382 opposite to each other in the first direction X. The abutment 1314 on both clamping blocks 131 abuts the first side 1380 and the second side 1382 of the wedge block 138, respectively. The wedge 138 is controllably reciprocated in a second direction Y, the distance between the first side 1380 and the second side 1382 being set to gradually increase or decrease in the second direction Y, which is perpendicular to the first direction X. In this way, because the distance between the first side surface 1380 and the second side surface 1382 gradually increases or decreases in the second direction Y, in the process that the wedge block 138 moves along the second direction Y, under the combined action of each of the first elastic members 134 and the wedge block 138, the two clamping blocks 131 can be driven to approach or separate from each other, so as to clamp or release the mandrel a on the supporting plate 132. Alternatively, the first elastic member 134 may be a spring.

Optionally, the two abutting portions 1314 are rollers, and the rollers on the two clamping blocks 131 can roll along the first side 1380 and the second side 1382, respectively. Thus, the two abutting parts 1314 are set as rollers, which is beneficial to reducing the friction force between the abutting parts 1314 and the wedge-shaped block 138, reducing the abrasion and delaying the service life on one hand; on the other hand, the flexibility of the movement of the wedge 138 is improved.

Further, the clamping structure 136 further includes a movable driving member 137 disposed on the mounting seat 130. The movable driving member 137 is connected to the wedge 138 such that the movable driving member 137 can drive the wedge 138 to reciprocate along the second direction Y. Alternatively, the movement driving member 137 may be a cylinder.

In an embodiment, the clamping structure 136 further includes two fixing blocks 133 and a guide rod 135, the two fixing blocks 133 are fixedly connected to the mounting base 130 at intervals along the first direction X, and the supporting plate 132 is located between the two fixing blocks 133. Both ends of the guide bar 135 are connected to the two fixing blocks 133, respectively. The two holding blocks 131 are slidably coupled to the guide bar 135 such that the two holding blocks 131 can move toward or away from each other along the guide bar 135. One of the first elastic members 134 abuts between one of the fixed blocks 133 and the adjacent one of the clamping blocks 131, and the other first elastic member 134 abuts between the other one of the fixed blocks 133 and the adjacent one of the clamping blocks 131. It should be noted that the number of the guide rods 135 may be two or more, so that the movement of the clamping block 131 is simultaneously guided by each guide rod 135, and the movement of the clamping block 131 is more stable and reliable.

Alternatively, both clamping blocks 131 have clamping parts 1311, the two clamping parts 1311 are arranged opposite in the first direction X, and the sides facing each other each have a clamping slope 1313. The two clamping portions 1311 respectively clamp or unclamp the core rod a on the pallet 132 by the respective clamping slopes 1313. The distance between the two clamping slopes 1313 is set to gradually decrease from one end close to the supporting plate 132 to one end far from the supporting plate 132 (i.e., the distance between the two clamping slopes 1313 gradually decreases from bottom to top as shown in fig. 5), so that when the two clamping portions 1311 clamp the core rod a on the supporting plate 132 between the two clamping slopes 1313, the clamping force applied to the core rod a has a component force toward the supporting plate 132 (i.e., a component force downward as shown in fig. 5), so that the core rod a is tightly pressed on the supporting plate 132 while being clamped, and the clamping of the core rod a is further stable.

Further, the supporting plate 132 has a positioning groove (not shown) for positioning the core rod a, and the positioning groove extends lengthwise in a second direction Y perpendicular to the first direction X. In this way, the core rod a is received in the positioning groove when the core rod a is dropped onto the supporting plate 132, so that the positioning groove is used to position the core rod a in the first direction X, thereby preventing the core rod a from rolling freely before being clamped by the two clamping blocks 131.

In the embodiment, the transfer mechanism 13 further includes a fixing spacer 141 connected to the mounting base 130, and the fixing spacer 141 is located at one end of the positioning groove in the second direction Y and is configured to abut against one end of the mandrel a located in the positioning groove, so as to position the mandrel a in the second direction Y. Referring to fig. 14, the transferring device 10 further includes a positioning mechanism 14 disposed at the blanking station B1, and the positioning mechanism 14 includes a movable positioning element 142. When the transferring mechanism 13 moves to the blanking station B1, the movable positioning element 142 is located at the other end of the positioning slot (that is, the movable positioning element 142 and the fixed positioning element 141 are respectively located at two ends of the positioning slot in the second direction Y), and the movable positioning element 142 can be controlled to move close to or away from the fixed positioning element 141 along the second direction Y, so as to clamp or release the mandrel a in the positioning slot together with the fixed positioning element 141 along the second direction Y. When the transfer mechanism 13 moves to the blanking station B1, the mandrel a fed out from the blanking device 20 first falls into the positioning groove of the pallet 132 of the transfer mechanism 13. Then, the movable positioning element 142 moves close to the fixed positioning element 141 along the second direction Y until the core rod a in the positioning slot is pressed against the fixed positioning element 141 (i.e. at this time, the movable positioning element 142 and the fixed positioning element 141 clamp the core rod a in the positioning slot together). Then, the movable positioning element 142 moves away from the fixed positioning element 141 along the second direction Y until returning to the initial position, and at this time, positioning of the core rod a in the positioning groove in the second direction Y is completed. Then, the two clamping blocks 131 are moved closer to each other until they clamp the core rod a in the positioning slot.

Further, the positioning mechanism 14 further includes a positioning driving member 144, a connecting block 143, and a buffering elastic member 146. The positioning driver 144 is mounted on the mounting plate 60, and the connecting block 143 is mounted at the driving end of the positioning driver 144 to be reciprocally moved in the second direction Y by the positioning driver 144. The movable positioning member 142 is movably coupled to the connection block 143 in the second direction Y. The buffering elastic member 146 abuts between the connection block 143 and the movable positioning member 142 to provide a pre-tightening force for making the movable positioning member 142 have a moving trend away from the connection block 143 along the second direction Y. Thus, when the mandrel a in the positioning groove needs to be positioned, the positioning driving member 144 drives the movable connecting block 143 to move close to the fixed positioning member 141 along the second direction Y, so that the movable positioning member 142 abuts against the mandrel a in the positioning groove and moves towards the fixed positioning member 141 until the mandrel a in the positioning groove is pressed against the fixed positioning member 141, and at this time, the buffering elastic member 146 is pressed to play a buffering role, thereby preventing the movable positioning member 142 and the fixed positioning member 141 from crushing the mandrel a. Alternatively, the damping elastic member 146 may be a spring, and the positioning driving member 144 may be a cylinder.

Referring to fig. 13 to 15, in the embodiment of the invention, the blanking device 20 includes a magazine 21 and a blanking wheel 22. The magazine 21 has a receiving cavity 210 and an opening 212, the receiving cavity 210 is used for receiving a plurality of core rods a, and the opening 212 is located at the bottom of the receiving cavity 210. The dropping wheel 22 is rotatably disposed below the magazine 21. The plurality of receiving grooves 221 are formed on the circumferential surface of the blanking wheel 22, and the plurality of receiving grooves 221 are arranged at intervals along the circumferential direction of the blanking wheel 22, so that the receiving grooves 221 pass through the opening 212 one by one in the rotation process of the blanking wheel 22. Each receiving slot 221 is used for receiving a mandrel a when rotating to the opening 212 with the blanking wheel 22, and transferring the mandrel a to the pallet 132 of the first transfer mechanism 13a of the transfer device 10 when rotating to the discharging position with the blanking wheel 22.

In actual use, the blanking wheel 22 rotates, so that each accommodating groove 221 on the blanking wheel 22 also rotates along with the blanking wheel 22. As the receiving groove 221 rotates past the opening 212, the mandrel a in the receiving cavity 210 enters the receiving groove 221 through the opening 212 and follows the receiving groove 221 away from the opening 212. When the housing tank 221 housing the plug a is rotated to the discharge position, the plug a in the housing tank 221 falls down onto the pallet 132 of the first transfer mechanism 13a reaching the blanking station B1 by its own weight.

In this way, each accommodating groove 221 is continuously driven by the rotation of the blanking wheel 22 to take the core rod a at the opening 212, and the core rod a is output at the discharging position, so that the transfer mechanism 13 can transfer the core rods a from the blanking station B1 to the adjusting station B2 one by one, that is, the continuous blanking of the core rods a is realized by the rotation of the blanking wheel 22, which is beneficial to improving the feeding efficiency of the core rods a.

Optionally, the opening 212 is located at the top of the blanking wheel 22, so that the core rods a in the receiving cavity 210 can fall under their own weight into the receiving groove 221 reaching the opening 212. The discharging position is located at the bottom of the blanking wheel 22 so that the core rods a rotated to reach the receiving grooves 221 at the bottom of the blanking disc 22 can fall down onto the pallet 132 of the first transfer mechanism 13a by their own gravity.

In one embodiment, the blanking device 20 further includes a guiding member 23, the guiding member 23 is disposed around the blanking wheel 22 and forms a conveying channel (not shown) with the peripheral side surface of the blanking wheel 22, so that the core rods a received in the receiving slots 221 move along the conveying channel along with the blanking wheel 22 during the rotation of the blanking wheel 22, and the core rods a are prevented from falling from the receiving slots 221 before reaching the discharging position. Guide 23 has an in-feed end 2210 at opening 212 and an out-feed end 2212 at the out-feed position. During the rotation of the blanking wheel 22, the core rods a accommodated in the accommodating grooves 221 enter the conveying path from the feeding end 2210 and are conveyed from the discharging end 2212 onto the pallet 132 of the transfer mechanism 13 reaching the blanking station B1.

In this way, the guiding element 23 prevents the core rods a located in the accommodating grooves 221 from falling before rotating to the discharging position along with the blanking wheel 22, so that the core rods a in each accommodating groove 221 can smoothly rotate to the discharging position along with the blanking wheel 22 and are conveyed to the supporting plate 132 of the transfer mechanism 13 reaching the blanking station B1.

It should be noted that the guide member 23 is not limited to prevent the core rod a from falling before it reaches the discharging position following the rotation of the dropping wheel 22. In other embodiments, the mandrel a may be fixed in the receiving groove 221 by magnetic attraction or clamping, and the mandrel a may be loosened when reaching the discharging position, so as to ensure that the mandrel a can smoothly reach the discharging position and fall onto the supporting plate 132 of the transferring mechanism 13 at the discharging position.

In particular embodiments, the blanking device 20 further includes a guide fitting 24 disposed at the discharge position. The guide fitting 24 and the discharge end 2212 of the guide 23 define a drop opening C therebetween. When the mandrel a accommodated in the accommodating groove 221 rotates to reach the blanking opening C along with the blanking wheel 22, the mandrel a falls down from the blanking opening C onto the supporting plate 132 of the transfer mechanism 13 under the action of its own weight. In this way, the mandrel a is blanked by the blanking opening C formed between the discharge end 2212 of the guide 23 and the guide fitting 24, and the position where the mandrel a is blanked is defined, so that the mandrel a can be ensured to accurately fall into the positioning groove on the pallet 132 of the transfer mechanism 13.

Further, the blanking device 20 further includes a mounting frame 25 and a blanking driving member 26. The mounting frame 25 is fixedly connected to the mounting plate 60, the magazine 21 is fixedly connected to the mounting frame 25, and the blanking wheel 22 is rotatably connected to the mounting frame 25. The blanking driver 26 is mounted on the mounting bracket 25 and connected to the blanking wheel 22, such that the blanking driver 26 can drive the blanking wheel 22 to rotate. The guide 23 and the guide fitting 24 are mounted on a mounting bracket 25. Alternatively, the blank drive 26 may be a motor.

Referring to fig. 16, in an embodiment of the present invention, the adjusting device 30 includes an adjusting mechanism 32. The adjusting mechanism 32 includes a first supporting base 320, and a first rotary joint shaft 321 and a second rotary joint shaft 322 both rotatably connected to the first supporting base 320 about their axes. The first supporting seat 320 is fixedly connected to the mounting plate 60. The first rotating abutment shaft 321 and the second rotating abutment shaft 322 have collinear axes (i.e., the first rotating abutment shaft 321 and the second rotating abutment shaft 322 are coaxial). The first rotary abutment shaft 321 and the second rotary abutment shaft 322 are spaced from each other, and the mandrel a transferred to the adjustment station by the transfer device 10 can be controllably moved between the first rotary abutment shaft 321 and the second rotary abutment shaft 322. The first and second rotary abutment shafts 321, 322 can be controlled to approach or move away from each other to clamp or unclamp the mandrel a between the first and second rotary abutment shafts 321, 322. Optionally, the axes of the first rotating butting shaft 321 and the second rotating butting shaft 322 are both parallel to the second direction Y, and the first rotating butting shaft 321 and the second rotating butting shaft 322 are arranged at intervals along the second direction Y.

The adjustment mechanism 32 further includes a detector 324 for detecting the position of the positioning portion a1 on the mandrel a clamped between the first rotary abutment shaft 321 and the second rotary abutment shaft 322. Alternatively, the detecting member 324 may be a correlation type photoelectric sensor.

In one embodiment, the adjusting device 30 further includes a gripping mechanism 31, the gripping mechanism 31 includes a gripping assembly 312, and the gripping assembly 312 can move to the material taking position and the adjusting position along a third direction Z, and the third direction Z intersects with both the first direction X and the second direction Y. Preferably, the third direction Z is perpendicular to both the first direction X and the second direction Y. When the gripping assembly 312 moves to the pickup position, it can grip the core rod a on the first transfer mechanism 13a that reaches the adjustment station B2 or place the core rod a on the second transfer mechanism 13B that reaches the adjustment station B2. When the clamping assembly 312 moves to the adjusting station B2, the mandrel a clamped by the clamping assembly 312 reaches between the first rotating abutting shaft 321 and the second rotating abutting shaft 322, so that the first rotating abutting shaft 321 and the second rotating abutting shaft 322 can approach each other to abut against both ends of the mandrel a, respectively, that is, the mandrel a is clamped by the first rotating abutting shaft 321 and the second rotating abutting shaft 322 along the second direction Y (i.e., the axial direction of the mandrel a).

In this way, when the first transfer mechanism 13a moves to the adjusting station B2, first, the gripping assembly 312 moves close to the first transfer mechanism 13a along the third direction Z until the gripping assembly 312 reaches the material taking position. At this time, the gripping assembly 312 grips the mandrel a on the first transfer mechanism 13a, and the gripping structure 136 of the first transfer mechanism 13a releases the grip of the mandrel a. Then, the gripping assembly 312 moves away from the first transfer mechanism 13a in the third direction Z until the adjustment position is reached. At this time, the mandrel a gripped by the gripping assembly 312 is located between the first rotating abutting shaft 321 and the second rotating abutting shaft 322, the first transfer mechanism 13a can be returned to the blanking station B1 from the adjusting station B2, and the second transfer mechanism 13B can be moved to the adjusting station B2. Then, the first rotation abutting shaft 321 and the second rotation abutting shaft 322 approach each other until they abut against both lengthwise ends of the core rod a (i.e., clamp the core rod a in the second direction Y), respectively. At this time, the clamping assembly 312 releases the mandrel a, and the first rotating and abutting shaft 321 and the second rotating and abutting shaft 322 rotate the mandrel a. When the detecting member 324 detects that the positioning portion a1 on the mandrel a reaches the preset position, the first rotation abutting shaft 321 and the second rotation abutting shaft 322 stop rotating, and the adjustment of the mandrel a is completed. Then, the gripping assembly 312 grips the mandrel a again, and the first and second rotary abutment shafts 321 and 322 move away from each other to release the mandrel a. Then, the gripping assembly 312 moves close to the second transfer mechanism 13b in the third direction Z until the core rod a is placed on the pallet 132 of the second transfer mechanism 13b and gripped by the gripping structure 136. Then, the gripping assembly 312 releases the core rod a and returns away from the second transfer mechanism 13b in the third direction Z. At this time, the second transfer mechanism 13B can be moved from the adjustment station B2 to the pasting station B3.

It is not limited to the case where the mandrel a reaches or leaves the position between the first rotation abutting shaft 321 and the second rotation abutting shaft 322 by the gripping mechanism 31. In other embodiments, the transfer mechanism 13 may be a transfer mechanism 13 having a lifting function, that is, the mandrel a may reach or leave a position between the first rotary abutment shaft 321 and the second rotary abutment shaft 322 by lifting and lowering the transfer mechanism 13 itself, which is not limited herein.

In a specific embodiment, the adjusting mechanism 32 further includes a guide shaft 323, and the guide shaft 323 is connected to an end of the first rotary abutting shaft 321 facing the second rotary abutting shaft 322. The guide shaft 323 inserts into or withdraws from the central hole of the mandrel a between the first and second rotary abutment shafts 321 and 322 while the first and second rotary abutment shafts 321 and 322 approach or move away from each other. In this way, when the gripping assembly 312 grips the mandrel a and reaches the adjustment position, the first rotating abutment shaft 321 and the second rotating abutment shaft 322 approach each other, so that the guide shaft 323 is inserted into the central hole of the mandrel a to guide the mandrel a until the first rotating abutment shaft 321 and the second rotating abutment shaft 322 abut against the two longitudinal ends of the mandrel a, respectively, to grip the mandrel a.

Of course, in other embodiments, the guide shaft 323 may be connected to an end of the second rotation abutting shaft 322 facing the first rotation abutting shaft 321, and may also serve to guide the mandrel a, which is not limited herein.

Referring to fig. 17 to 18, in an embodiment, the adjusting mechanism 32 further includes a first moving seat 325 and a first driving member 326. The first moving base 325 is movably coupled to the first supporting base 320 in the second direction Y. The first rotary abutment shaft 321 is rotatably connected to the first movable seat 325 about its own axis, so that the first movable seat 325 can drive the first rotary abutment shaft 321 to move along the second direction Y. The first driving member 326 is mounted on the first supporting seat 320 and connected to the first moving seat 325, so that the first driving member 326 can drive the first moving seat 325 to move along the second direction Y relative to the first supporting seat 320, and the first moving seat 325 drives the first rotation abutting shaft 321 to approach or depart from the second rotation abutting shaft 322. Alternatively, the first drive 326 may be a cylinder.

Optionally, the first supporting seat 320 is provided with a second sliding rail 3202 extending lengthwise along the second direction Y, and the first moving seat 325 is provided with a second sliding block 3203 slidably engaged with the second sliding rail 3202. In this way, the movement of the first moving base 325 in the second direction Y with respect to the first supporting base 320 is guided by the movement of the second slider 3203 along the second slide rail 3202.

Optionally, the first rotary abutment shaft 321 is mounted on the first movable seat 325 by a bearing, so that the first rotary abutment shaft 321 can rotate relative to the first movable seat 325.

In one embodiment, the adjusting mechanism 32 further includes a second movable base 328 and a second driving member 329. The second movable base 328 is movably coupled to the first support base 320 in the second direction Y. The second rotary butting shaft 322 is rotatably connected to the second moving base 328 around its axis, so that the second rotary butting shaft 322 can move along the second direction Y under the driving of the second moving base 328. The second driving member 329 is installed on the first supporting seat 320 and connected to the second moving seat 328, so that the second driving member 329 can drive the second moving seat 328 to move along the second direction Y relative to the first supporting seat 320, and the second moving seat 328 drives the second rotary abutting shaft 322 to approach or leave the first rotary abutting shaft 321. Alternatively, the second driver 329 may be a cylinder.

Optionally, a third sliding rail 3201 longitudinally extending along the second direction Y is disposed on the first supporting seat 320, and a third sliding block slidably engaged with the third sliding rail 3201 is disposed on the second moving seat 328. In this way, the movement of the second movable base 328 in the second direction Y with respect to the first support base 320 is guided by the movement of the third slider along the third slide rail 3201.

Optionally, second rotary abutment shaft 322 is bearing-mounted on second movable mount 328 such that second rotary abutment shaft 322 is rotatable relative to second movable mount 328.

Specifically, the adjusting mechanism 32 further includes a first rotary driving member 327 mounted on the first moving seat 325, and the first rotary driving member 327 is connected to the first rotary butting shaft 321, so that the first rotary driving member 327 can drive the first rotary butting shaft 321 to rotate, and further drive the mandrel a clamped by the first rotary butting shaft 321 and the second rotary butting shaft 322 to rotate. Further, the output shaft of the first rotary driving element 327 is connected to the first rotary butting shaft 321 through a belt transmission structure 3271, so that the rotary motion output by the first rotary driving element 327 is transmitted to the first rotary butting shaft 321 through the belt transmission structure 3271, and the first rotary butting shaft 321 is driven to rotate.

Of course, in another embodiment, the first rotary driving element 327 may be mounted on the second movable seat 328, and the first rotary driving element 327 is connected to the second rotary abutting shaft 322, so that the first rotary driving element 327 can drive the second rotary abutting shaft 322 to rotate, and further drive the mandrel clamped by the first rotary abutting shaft 321 and the second rotary abutting shaft 322 to rotate.

In some embodiments, the adjustment mechanism 32 further includes an adjustment seat (not shown) disposed on the first support base 320, and the detector 324 is mounted on the adjustment seat. The position of the adjusting base is adjustable relative to the first supporting base 320, so that the position of the detecting member 324 can be adjusted by the adjusting base. Optionally, the position of the adjustment seat relative to the first support seat 320 is adjustable along the second direction Y and/or the third direction Z. Therefore, the position of the adjusting seat relative to the first supporting seat 320 is adjusted along the second direction Y and/or the third direction Z, so that the purpose of adjusting the position of the detecting piece 324 in the second direction Y and/or the third direction Z is achieved, core rods a with different specifications are used, and the compatibility of the equipment is improved.

Further, the adjustment base includes a first adjustment block 3241, a first threaded fastener, a second adjustment block 3242, and a second threaded fastener. The first adjusting block 3241 is formed with a first kidney-shaped hole 3243, and the first kidney-shaped hole 3243 extends lengthwise along the second direction Y. The first threaded locking member is inserted into the first kidney-shaped hole 3243 and is in threaded connection with the first supporting seat 320, so as to fasten the first adjusting block 3241 on the first supporting seat 320. The second adjusting block 3242 is formed with a second kidney-shaped hole 3244, and the second kidney-shaped hole 3244 extends lengthwise along a third direction Z. The second threaded fastener is inserted into the second waist-shaped hole 3244 and is in threaded connection with the first adjusting block 3241, so that the second adjusting block 3242 is fastened on the first adjusting block 3241. The sensing member 324 is mounted on the second regulation block 3242 to perform position regulation along with the second regulation block 3242. Alternatively, the first threaded fastener and the second threaded fastener may both employ locking screws.

Thus, when the position of the detecting element 324 in the second direction Y needs to be adjusted, the first threaded locking element is firstly loosened, and the first adjusting block 3241 is pushed to move along the second direction Y relative to the first supporting seat 320, so as to drive the second adjusting block 3242 and the detecting element 324 to move along the second direction Y. When the position of the detecting member 324 in the second direction Y is adjusted, the first threaded locking member is tightened to lock the first adjusting block 3241 on the first supporting seat 320.

When the position of the detecting member 324 in the third direction Z needs to be adjusted, the second threaded locking member is first unscrewed, and the second adjusting block 3242 is pushed to move along the third direction Z relative to the first adjusting block 3241, so as to drive the detecting member 324 to move along the third direction Z. After the position of the detecting member 324 in the third direction Z is adjusted, the second threaded locking member is tightened to lock the second adjusting block 3242 to the first adjusting block 3241.

Referring to fig. 19 and 20, in some embodiments, the gripping mechanism 31 further includes a second driving assembly, which includes a second supporting base 310, a third moving base 311 and a third driving member 313. The second support base 310 is fixedly connected to the mounting plate 60, and the third movable base 311 is movably connected to the second support base 310 along the third direction Z. The gripping assembly 312 is mounted on the third moving base 311 such that the gripping assembly 312 moves along with the third moving base 311 in the third direction Z. The third driving element 313 is disposed on the second supporting seat 310 and connected to the third moving seat 311, so that the third driving element 313 can drive the third moving seat 311 to move along the third direction Z relative to the second supporting seat 310, and drive the gripping assembly 312 to move to the material taking position or the adjusting position. When the clamping assembly 312 moves to the adjustment position, the mandrel a on the clamping assembly 312 is located between the first rotating abutting shaft 321 and the second rotating abutting shaft 322 and is coaxial with the first rotating abutting shaft 321 and the second rotating abutting shaft 322, so that when the first rotating abutting shaft 321 and the second rotating abutting shaft 322 clamp the mandrel a and drive the mandrel a to rotate, the rotation of the first rotating abutting shaft 321, the second rotating abutting shaft 322 and the mandrel a is smooth and stable.

Optionally, the second drive assembly further comprises a second lead screw 314 and a second lead screw nut 315. The second lead screw 314 is rotatably connected to the second support seat 310 around its axis, and the axial direction of the second lead screw 314 is parallel to the third direction Z. The third driving element 313 is connected with the second screw 314, so that the third driving element 313 can drive the second screw 314 to rotate around the axis thereof. The second lead screw nut 315 is screwed on the second lead screw 314 and is fixedly connected with the third moving seat 311, so that the third moving seat 311 and the second lead screw nut 315 move together. In this way, when the third driving element 313 drives the second lead screw 314 to rotate, the second lead screw nut 315 moves along the third direction Z (i.e. the axial direction of the second lead screw 314), so as to drive the third moving seat 311 and the clamping assembly 312 to move along the third direction Z between the material taking position and the adjusting position, thereby ensuring that the mandrel a on the clamping assembly 312 is coaxial with the first rotating abutting shaft 321 and the second rotating abutting shaft 322 when the clamping assembly 312 reaches the adjusting position. Alternatively, the third driver 313 may be an electric motor.

Optionally, the second supporting seat 310 is provided with two guide rods 316 that both extend lengthwise along the third direction Z, and the third moving seat 311 is slidably disposed on the two guide rods 316. In this way, the two guide rods 316 are used to guide the movement of the third movable seat 311 relative to the second support seat 310 along the third direction Z.

In one embodiment, the clamping assembly 312 includes a clamping jaw cylinder (not shown) and two clamping jaws (not shown) mounted at a driving end of the clamping jaw cylinder, wherein the clamping jaw cylinder is used for driving the two clamping jaws to move toward or away from each other so as to clamp or release the mandrel. Of course, in other embodiments, the gripping assembly 312 may have other jaw configurations, as long as it can grip or release the mandrel, and is not limited herein.

Referring to fig. 21 and 22, in an embodiment of the present invention, the adhesive applying device 40 includes a moving mechanism 41, an unwinding mechanism 43, a winding mechanism 44, an adhesive applying mechanism 45, and a cutting mechanism 46. The moving mechanism 41 includes a first driving assembly 411 and a transfer base 412 connected to the first driving assembly 411 in a transmission manner. The first driving assembly 411 is used for driving the transfer base 412 to move along the second direction Y and the third direction Z. The second direction Y intersects with a third direction Z, which is preferably perpendicular to the second direction Y. The unwinding mechanism 43 is disposed on the transfer base 412, and is configured to unwind the double-sided adhesive tape a3, where the double-sided adhesive tape a3 includes a double-sided adhesive layer a2 and a separation film a4 that are stacked. The winding mechanism 44 is disposed on the transfer base 412 and is configured to wind the release film a4 of the double-sided tape a 3. The taping mechanism 45 is provided on the carriage 412 and has a taping wheel 451 around which the double-sided adhesive tape a3 is passed. The cutting mechanism 46 is provided on the transfer base 412 for cutting the double-sided adhesive layer a2 of the double-sided adhesive tape a3 from the upstream side of the taping wheel 451 so that the separator a4 of the double-sided adhesive tape a3 remains continuous and is finally wound up by the winding mechanism 44.

In the process that the transferring seat 412 moves along the third direction Z, the gluing wheel 451 can be driven to press the double-sided glue layer a2 against the core rod a on the transferring mechanism 13 reaching the gluing station. During the process that the transfer base 412 moves along the second direction Y, the tape attaching wheel 451 can be driven to roll along the surface of the mandrel a on the transfer mechanism 13, so as to attach the double-sided tape layer a2 to the mandrel a on the transfer mechanism 13.

In the actual gluing operation, when the transfer mechanism 13 carries the core rod a and moves from the adjusting station B2 to the gluing station B3, the transfer base 412 moves toward the core rod a on the transfer mechanism 13 along the third direction Z until the gluing wheel 451 is driven to press the double-sided tape a3 against the core rod a. At this time, the double-sided adhesive layer a2 of the double-sided adhesive tape a3 is in contact with the surface of the mandrel a, and the separator a4 of the double-sided adhesive tape a3 is positioned between the double-sided adhesive layer a2 and the applicator wheel 451. Then, the transferring seat 412 moves a preset distance along the second direction Y (i.e. the axial direction of the mandrel a) (meanwhile, the winding mechanism 44 winds the isolation film a4, and the unwinding mechanism 43 unwinds the double-sided adhesive tape a 3), so as to drive the tape pasting wheel 451 to roll along the surface of the mandrel a, so as to paste the double-sided adhesive layer a2 on the mandrel a. Then, the cutting mechanism 46 cuts the two-sided adhesive layer a2 of the two-sided adhesive tape a3 (without cutting the separator a4 of the two-sided adhesive tape a 3) from the upstream side of the taping wheel 451, and the cut two-sided adhesive layer a2 is stuck to the mandrel a. Then, the transfer base 412 moves away from the mandrel a on the transfer mechanism 13 in the third direction Z and returns to the initial position to prepare for the next taping operation. So, above-mentioned rubberizing device 40 can realize automatic and continuous rubberizing action, and degree of automation is high, and rubberizing action process is reliable and stable, is favorable to improving the stability of rubberizing efficiency and rubberizing quality.

The upstream side of the applicator wheel 451 is relative to the conveyance of the double-sided tape a3, that is, the position where the double-sided tape a3 passes first is upstream, and the position where the double-sided tape a3 passes later is downstream.

In particular embodiments, the first driving assembly 411 includes a base 4110, a motion base 4112, a first motion driving member 4113, and a second motion driving member 4114. The base 4110 is fixedly mounted on the large mounting plate 60, the moving base 4112 is movably connected to the base 4110 along the second direction Y, and the transferring base 412 is movably connected to the moving base 4112 along the third direction Z. The first motion driving element 4113 is disposed on the base 4110 and is drivingly connected to the motion base 4112 to drive the motion base 4112 to move relative to the base 4110 along the second direction Y. The second motion driving member 4114 is disposed on the motion base 4112 and is connected to the transfer base 412 for driving the transfer base 412 to move along the third direction Z relative to the motion base 4112. Thus, when the tape adhering wheel 451 needs to be driven to move along the third direction Z so as to make the tape adhering wheel 451 abut against or separate from the mandrel a on the transferring mechanism 13, the second motion driving member 4114 may be used to drive the transferring base 412 to move along the third direction Z relative to the moving base 4112. When the rubberizing wheel 451 needs to be driven to move along the second direction Y so that the rubberizing wheel 451 rolls along the axial direction of the mandrel, the first motion driving member 4113 can be used to drive the motion base 4112 to move along the second direction Y, so as to drive the rubberizing wheel 451 to roll along the axial direction of the mandrel, and the rubberizing wheel 451 is used to stick the double-sided adhesive layer a2 on the mandrel a.

Alternatively, the first and second motion drivers 4113, 4114 may be a lead screw pair drive arrangement. Of course, in other embodiments, other linear driving structures are also possible, and are not limited herein.

Optionally, a fourth sliding rail extending lengthwise in the second direction Y is disposed on the base 4110, and a fourth slider slidably engaged with the fourth sliding rail is disposed on the moving seat 4112. In this way, the movement of the moving base 4112 relative to the base 4110 along the second direction Y is guided by the movement of the fourth slider along the fourth slide rail.

Optionally, a fifth slide rail extending lengthwise in the third direction Z is disposed on the moving base 4112, and a fifth slider slidably engaged with the fifth slide rail is disposed on the transferring base 412. In this way, the movement of the transfer base 412 relative to the moving base 4112 along the third direction Z is guided by the movement of the fifth slider along the fifth slide rail.

It should be noted that, in other embodiments, the moving base 4112 may be movable along the third direction Z relative to the base 4110, and the transferring base 412 may be movable along the second direction Y relative to the moving base 4112, as long as the tape attaching wheel 451 can be driven to move along the second direction Y and the third direction Z, which is not limited herein.

In an embodiment, the adhesive applying device 40 further includes a pressing mechanism 47 disposed on the transferring base 412, and the pressing mechanism 47 has a pressing wheel 471 located at a downstream side of the adhesive applying wheel 451. When the gluing wheel 451 presses the double-sided adhesive layer a2 against the mandrel a on the transfer mechanism 13 reaching the gluing station B3, the pressing wheel 471 is also pressed against the mandrel a on the transfer mechanism 13 reaching the gluing station B3, so that the pressing wheel 471 flattens the double-sided adhesive layer a2 stuck on the mandrel a in the process of moving along the second direction Y along with the transfer base 412. In this way, while the taping wheel 451 rolls in the axial direction of the mandrel a (i.e., the second direction Y), the double-sided adhesive layers a2 of the double-sided adhesive tape a3 are stuck to the mandrel a. Meanwhile, the pressing wheel 471 also rolls along the axial direction of the core rod a to further press (i.e., smooth) the double-sided adhesive layer a2 adhered to the core rod a onto the core rod a, so that the double-sided adhesive layer a2 and the core rod a are adhered more closely.

As shown in fig. 26 to fig. 28, further, the circumferential side surface of the pressing wheel 471 is recessed inward to form a recessed surface 4710, and the recessed surface 4710 is used for matching with the circumferential side surface of the mandrel a, so as to increase the pressing area of the pressing wheel 471 and the mandrel a, and improve the effect of pressing the double-sided adhesive layer a2 on the mandrel a. Alternatively, the outer surface of the core rod a is a circular arc surface, and thus the concave surface 4710 on the pressing wheel 471 is also a circular arc surface, so that the concave surface 4710 can be fitted with the outer surface of the core rod a.

Specifically, in the embodiment, the pressing mechanism 47 includes a connection seat 472, a support shaft 473 and a second elastic member 474. The connecting seat 472 is disposed on the transfer seat 412. The supporting shaft 473 is movably connected to the connecting seat 472, and the pressing wheel 471 is rotatably connected to the supporting shaft 473. The second elastic member 474 abuts between the supporting shaft 473 and the connecting seat 472 to provide a pre-tightening force for the supporting shaft 473 to drive the pressing wheel 471 to move closer to the core rod a. Alternatively, the second elastic member 474 may be a spring.

Thus, when the transferring seat 412 drives the gluing wheel 451 and the pressing wheel 471 to move close to the mandrel a along the third direction Z, the pressing wheel 471 is firstly abutted against the mandrel a, the second elastic member 474 is compressed and contracted along with the transferring seat 412 continuously driving the gluing wheel 451 to move towards the mandrel a until the gluing wheel 451 presses the double-sided adhesive layer a2 of the double-sided adhesive tape a3 against the mandrel a (i.e. the gluing wheel 451 and the pressing wheel 471 are both pressed against the mandrel a at this time). After the rubberizing wheel 451 and the pressing wheel 471 are both pressed on the mandrel a, the moving seat 4112 drives the rubberizing wheel 451 and the pressing wheel 471 to roll along the axial direction of the mandrel a together, so that the rubberizing wheel 451 adheres the double-sided adhesive layer a2 of the double-sided adhesive tape a3 to the mandrel a, and the pressing wheel 471 is pressed on the mandrel a. When the moving base 4112 stops moving after moving in the second direction Y by the preset distance, the cutting mechanism 46 cuts the two-sided adhesive layer a2 of the two-sided adhesive tape a3 from the upstream side of the taping wheel 451. Then, the moving seat 4112 drives the rubberizing wheel 451 and the pressing wheel 471 to continuously roll for a certain distance along the core rod a, so that the tail end of the cut double-sided adhesive layer a2 is pressed against the core rod a by the rubberizing wheel 451. Then, the transferring seat 412 drives the tape applying wheel 451 to move away from the mandrel a for a certain distance along the third direction Z, so that the tape applying wheel 451 is separated from the mandrel a, and the pressing wheel 471 keeps abutting against the mandrel a under the elastic force provided by the second elastic member 474. Then, the moving seat 4112 drives the pressing wheel 471 to roll for a certain distance along the axial direction of the core rod a, so that the tail end of the cut double-sided adhesive layer a2 is also pressed on the core rod a by the pressing wheel 471. Finally, the moving base 4112 and the transferring base 412 are respectively returned to the initial positions in the second direction Y and the third direction Z to prepare for the next pasting.

Alternatively, the coupling seat 472 is formed with a mounting groove 4721, and the support shaft 473 is disposed in the mounting groove 4721 such that the support shaft 473 can move along the mounting groove 4721 (i.e., along the third direction Z) by a certain stroke. One end of the second elastic member 474 abuts against the connection seat 472, and the other end abuts against the support shaft 473, so that the pressing wheel 471 can overcome the elastic force of the second elastic member 474 to move along the third direction Z relative to the connection seat 472 when receiving external pressure. Alternatively, the second elastic member 474 may be a spring pin.

Referring to fig. 23 to 25, in some embodiments, the rubberizing mechanism 45 further includes a first limiting block 453, and the cutting mechanism 46 includes a cutter holder 462, and a cutter 463 and a second limiting block 464 disposed on the cutter holder 462. The cutter holder 462 is disposed on the carriage 412 such that the cutter holder 462 moves together with the carriage 412. The first limiting block 453 and the second limiting block 464 are disposed opposite to each other along the second direction Y, and a tape passing channel h for the double-sided tape a3 to pass through is formed between the first limiting block 453 and the second limiting block 464. The adhesive passing channel h is located on the upstream side of the adhesive applying wheel 451, that is, the double-sided adhesive tape a3 unwound by the unwinding mechanism 43 passes through the adhesive passing channel h and then bypasses the adhesive applying wheel 451, the adhesive applying wheel 451 adheres the double-sided adhesive tape a2 of the double-sided adhesive tape a3 to the mandrel a, and the isolation film a4 of the double-sided adhesive tape a3 is wound on the winding mechanism 44.

The cutter holder 462 is movable to a cutting position in the second direction Y toward the taping mechanism 45. When the cutter holder 462 moves to the cutting position, the second limiting block 464 abuts against the first limiting block 453, and the cutter 463 cuts off the double-sided adhesive layer a2 from the space between the first limiting block 453 and the rubberizing wheel 451. In this way, the first stopper 453 and the second stopper 464 limit the cutting depth of the cutting blade 463, so that the cutting blade 463 is ensured to cut only the double-sided adhesive tape a2 of the double-sided adhesive tape a3 without cutting the separation film a4 of the double-sided adhesive tape a3 every time it cuts.

In an embodiment, the cutting mechanism 46 further includes a cutting driving member 461, the cutting driving member 461 is mounted on the carriage 412, and the cutter holder 462 is mounted at a driving end of the cutting driving member 461. The cutting driving member 461 is used for driving the cutter holder 462 to move toward the taping mechanism 45, so as to drive the cutter 463 to cut the double-sided tape a2 of the double-sided tape a3 from the upstream side of the taping wheel 451. Alternatively, the cutting drive 461 may be a pneumatic cylinder.

In one embodiment, the taping mechanism 45 includes a taping station 452 disposed on the transfer station 412. The taping wheel 451 is rotatably connected to the taping seat 452. The first limiting block 453 is disposed on the adhesive base 452, and the position of the first limiting block relative to the adhesive base 452 is adjustable along the second direction Y, so that the double-sided tape a3 and the mandrel a with different specifications can be adapted to, and compatibility of the apparatus is improved.

Further, the first stopper 453 is movably coupled to the sticker base 452 in the second direction Y. The first stopper 453 has a first inclined surface 4531, and the first inclined surface 4531 is inclined with respect to a plane perpendicular to the second direction Y. The taping mechanism 45 further includes an adjusting wedge 454 provided on the taping seat 452, the adjusting wedge 454 having a second inclined surface 4541 parallel to the first inclined surface 4531 and abutting against each other.

The adjusting wedge 454 is movable relative to the adhesive base 452 along a predetermined direction perpendicular to the second direction Y, so as to push the first limiting block 453 to move along the second direction Y under the guiding action of the first inclined surface 4531 and the second inclined surface 4541, thereby adjusting the position of the first limiting block 453 relative to the adhesive base 452 along the second direction Y. Thus, when the position of the first limiting block 453 needs to be adjusted, the adjusting wedge 454 is controlled to move along the preset direction, so as to drive the first limiting block 453 to move along the second direction Y relative to the adhesive base 452, i.e., the position of the first limiting block 453 is adjusted. Optionally, the preset direction is parallel to the first direction X.

Further, the rubberizing base 452 has a resisting surface 4520, and the resisting surface 4520 is located on a side of the first limiting block 453 away from the second limiting block 464. The adjusting wedge 454 is located between the first stopper 453 and the withstanding surface 4520. That is, the second stopper 464, the first stopper 453, the adjusting wedge 454, and the abutting surface 4520 are arranged in this order in the second direction Y. The first stopper 453 and the adjustment wedge 454 abut against each other via the first inclined surface 4531 and the second inclined surface 4541, and the adjustment wedge 454 and the abutting surface 4520 abut against each other.

The resisting surface 4520 is parallel to a plane perpendicular to the second direction Y, so that during the process of moving the adjusting wedge 454 in the preset direction and pushing the first limiting block 453 to move in the second direction Y, the resisting surface 4520 limits the position of the adjusting wedge 454 in the second direction Y, and prevents the adjusting wedge 454 from displacing in the second direction Y.

Further, the taping mechanism 45 further includes an adjusting screw 455, and the adjusting screw 455 is rotatably connected to the taping seat 452 about its axis. The axial direction of the adjusting screw 455 is parallel to the preset direction, and one end of the adjusting screw 455 is in threaded connection with the adjusting wedge 454, so that the adjusting wedge 454 can be driven to move along the preset direction by screwing the adjusting screw 455, and further, the first limiting block 453 is pushed to move along the second direction Y.

Further, the first stopper 453 has a third waist-shaped hole 4532 extending lengthwise along the second direction Y. The rubberizing mechanism 45 further comprises a threaded fastener (not shown) penetrating through the third waist-shaped hole 4532 and in threaded connection with the rubberizing seat 452, so as to lock and fix the first limiting block 453 on the rubberizing seat 452. Thus, when the position of the first limiting block 453 needs to be adjusted, the threaded fastener is firstly unscrewed, so that the first limiting block 453 can move relative to the adhesive base 452 along the second direction Y. Then, the adjusting screw 455 is screwed so as to drive the adjusting wedge 454 to move along the preset direction relative to the adhesive seat 452, and further drive the first limiting block 453 to move along the second direction Y relative to the adhesive seat 452. After the position of the first limiting block 453 is adjusted to the right position, the adjusting screw 455 stops rotating, and the threaded fastener is tightened to lock and fix the first limiting block 453 on the adhesive base 452. Alternatively, the threaded fastener may employ a fastening screw.

Referring to fig. 29 and 30, in the embodiment of the present invention, the feeding device 50 includes a feeding driving mechanism 51 and a clamping mechanism 52. The feeding driving mechanism 51 is connected with the clamping mechanism 52, so that the feeding driving mechanism 51 can drive the clamping mechanism 52 to move between the feeding station and the winding mechanism D along the first direction X. When the gripping mechanism 52 is located at the loading station, the gripping mechanism 52 can grip the core rod a on the transfer mechanism 13 that has reached the loading station. When the gripping mechanism 52 is located at the winding mechanism D, the gripping mechanism 52 can place the gripped mandrel a on the winding mechanism D. In this way, when the transfer mechanism 13 reaches the loading station with the adjusted mandrel a, first, the loading driving mechanism 51 drives the clamping mechanism 52 to move to the loading station along the first direction X, and the clamping mechanism 52 clamps the mandrel a on the transfer mechanism 13 at the loading station. Then, the feeding driving mechanism 51 drives the clamping mechanism 52 to move to the winding mechanism D along the first direction X, and at this time, the winding needle of the winding mechanism D extends and is inserted into the mandrel a, so that the positioning portion a1 of the mandrel a is matched with the winding needle. The clamping mechanism 52 then releases the mandrel a and returns to the loading station.

In a specific embodiment, the feeding driving mechanism 51 is further configured to drive the clamping mechanism 52 to move along the third direction Z, so that the clamping mechanism 52 can approach or separate from the core rod a on the transfer mechanism 13 along the third direction Z at the feeding station, thereby clamping the core rod a on the transfer mechanism 13. In this way, when the mandrel a on the transfer mechanism 13 which reaches the loading station needs to be gripped, the loading drive mechanism 51 drives the gripping mechanism 52 to move closer to the mandrel a on the transfer mechanism 13 in the third direction Z until the gripping mechanism 52 can grip the mandrel a. Then, the mandrel a is gripped by the gripping mechanism 52, and the mandrel a is released by the gripping mechanism 136 of the transfer mechanism 13. Then, the feeding driving mechanism 51 drives the clamping mechanism 52 to move away from the transfer mechanism 13 along the third direction Z and return, so that the clamping mechanism 52 drives the mandrel a to separate from the transfer mechanism 13, that is, the mandrel a is clamped.

In a specific embodiment, the feeding driving mechanism 51 is further configured to drive the clamping mechanism 52 to rotate around a rotation axis, so as to drive the mandrel a clamped on the clamping mechanism 52 to align with the winding needle of the winding mechanism D at the winding mechanism D, thereby enabling the winding needle to be accurately inserted into the mandrel a. In this way, when the feeding driving mechanism 51 drives the clamping mechanism 52 to move to the winding mechanism D along the first direction X, first, the feeding driving mechanism 51 drives the clamping mechanism 52 to rotate around the rotation axis until the mandrel a on the clamping mechanism 52 is aligned with the winding needle of the winding mechanism D. At this time, the winding needle of the winding mechanism D is extended and inserted into the mandrel a until the positioning portion a1 of the mandrel a matches the winding needle. Then, the clamping mechanism 52 releases the mandrel a and returns to the feeding station by the feeding driving mechanism 51, so as to perform the next feeding operation. Optionally, the rotation axis is parallel to the second direction Y.

Further, the loading driving mechanism 51 includes a third supporting seat 510, a fourth moving seat 511, a fourth driving member 513, a fifth moving seat 512, a fifth driving member 515 and a second rotary driving member 516. The third support base 510 is fixedly connected to the mounting plate 60. The fourth movable base 511 is movably coupled to the third support base 510 along the first direction X. The fourth driving part 513 is installed on the third supporting seat 510 and connected to the fourth moving seat 511, so that the fourth driving part 513 can drive the fourth moving seat 511 to move along the first direction X relative to the third supporting seat 510. The fifth movable base 512 is movably coupled to the fourth movable base 511 in the third direction Z. The fifth driving element 515 is mounted on the fourth movable base 511 and connected to the fifth movable base 512, so that the fifth driving element 515 can drive the fifth movable base 512 to move along the third direction Z relative to the fourth movable base 511. The second rotary driving member 516 is mounted on the fifth movable base 512, and the holding mechanism 52 is mounted at the driving end of the second rotary driving member 516 to be rotated about the above-mentioned rotation axis by the second rotary driving member 516. Alternatively, fifth drive 515 may be a pneumatic cylinder. The second rotary drive 516 may be a rotary air cylinder.

Optionally, the loading driving mechanism 51 further comprises a third lead screw 514 and a third lead screw nut (not shown). The third screw 514 is rotatably connected to the third support seat 510 around its axis, and the axial direction of the third screw 514 is parallel to the first direction X. The fourth driving member 513 is connected to the third lead screw 514, so that the fourth driving member 513 can drive the third lead screw 514 to rotate around its axis. The third screw nut is screwed on the third screw 514 and is fixedly connected with the fourth movable base 511. In this way, when the fourth driving part 513 drives the third lead screw 514 to rotate, the third lead screw nut moves along the axial direction (i.e. the first direction X) of the third lead screw 514, so as to drive the fourth movable base 511 to move along the first direction X. Alternatively, the fourth driving member 513 may be a motor.

Optionally, a sixth sliding rail 5101 longitudinally extending along the first direction X is disposed on the third supporting seat 510, and a sixth slider 5112 slidably engaged with the sixth sliding rail 5101 is disposed on the fourth movable seat 511. In this way, the movement of the fourth movable base 511 along the first direction X relative to the third support base 510 is guided by the movement of the sixth slider 5112 along the sixth slide rail 5101.

Optionally, a seventh sliding rail 5110 longitudinally extending along the third direction Z is disposed on the fourth movable seat 511, and a seventh sliding block 5120 slidably engaged with the seventh sliding rail 5110 is disposed on the fifth movable seat 512. In this way, the movement of the fifth movable base 512 in the third direction Z relative to the fourth movable base 511 is guided by the movement of the seventh slider 5120 along the seventh slide rail 5110.

Based on the mandrel feeding equipment, the invention also provides a battery winder. The battery winder comprises a winding mechanism D and mandrel feeding equipment in any one of the embodiments. The loading device 50 of the mandrel loading apparatus is used to transfer the mandrel a arriving at the loading station to the winding mechanism D. And the winding needle of the winding mechanism D extends out, so that the winding needle is inserted into the central hole of the core rod A, and the positioning part a1 of the core rod A is in positioning fit with the winding needle, so that the winding needle can drive the core rod A to rotate. So, when needs carry out the coiling operation, the tip in coiling material area passes through two-sided glue layer a2 bonding to be fixed on plug A, and the book needle drives plug A rotation to make the coiling material area coil form electric core on plug A. Alternatively, the wound tape may be a membrane.
