Description

Technical Field

[0001] The present application relates to the technical field of roll changing and tape splicing, and in particular to an automatic roll changing device. Background Art

[0002] Existing battery manufacturing generally uses fully automatic winding equipment, but in the production process, fully automatic winding, lamination, bag making and other processes include the process of unwinding the diaphragm roll. At present, an automatic splicing mechanism is generally used to connect the new and old rolls. This requires human assistance and manual preparation of glue before splicing.

[0003] The need for manual preparation of glue will reduce the efficiency of the machine, increase labor costs, and increase the chance of contact between people and the diaphragm, causing contamination of the diaphragm material and affecting the quality of the battery cell. Summary of the invention

[0004] The present application provides an automatic roll changing device, which solves the problem in the prior art of reduced machine efficiency and increased labor costs due to manual glue preparation.

[0005] The present application provides an automatic roll-changing device, which includes a first mounting plate, a first unwinding mechanism, a second unwinding mechanism, a tape splicing mechanism, and an automatic glue preparation mechanism. The first unwinding mechanism, the second unwinding mechanism, and the tape splicing mechanism are arranged on the first mounting plate, and the tape splicing mechanism is used to splice the material tape unwound by the first unwinding mechanism with the material tape unwound by the second unwinding mechanism. The automatic glue preparation mechanism is arranged on the first mounting plate, and the automatic glue preparation mechanism is used to prepare double-sided adhesive tape on the material tape unwound by the first unwinding mechanism and / or the second unwinding mechanism.

[0006] In the above scheme, an automatic roll-changing device that can automatically complete glue preparation and tape splicing is provided. The first mounting plate, the first unwinding mechanism, the second unwinding mechanism, the tape splicing mechanism and the automatic glue preparation mechanism are all arranged on the first mounting plate, and the first unwinding mechanism and the second unwinding mechanism are used to unwind new tape and old tape. Before the tape splicing mechanism splices the new and old tapes, the double-sided tape will be separated from the release paper by the automatic glue preparation mechanism, and a section of the glue will be attached to the tape unwound by the first unwinding mechanism and / or the second unwinding mechanism, and then the new and old material rolls will be spliced ​​by the automatic tape splicing mechanism. Since the glue preparation work of the double-sided tape can be completed by the automatic glue preparation mechanism, it can improve production efficiency and reduce labor costs.

[0007] In a possible implementation, the automatic glue preparation mechanism includes a first driving mechanism, a second mounting plate, a glue paper unwinding mechanism, a release paper rewinding mechanism and a glue stripping block, wherein the release paper rewinding mechanism and the glue stripping block are mounted on the second mounting plate, the double-sided glue unwinded by the glue paper unwinding mechanism passes through the glue stripping block, the release paper rewinding mechanism is located downstream of the glue stripping block, and the release paper rewinding mechanism is used to rewind the release paper of the double-sided glue.

[0017] The automatic glue preparation mechanism also includes a double-sided glue fixing mechanism, which is arranged on the second mounting plate and is used to cooperate with the first roller to compress or loosen the double-sided glue.

[0018] In the above scheme, when the first driving mechanism drives the adhesive stripping block away from the material belt and the adhesive tape is torn off, the double-sided adhesive tape fixing mechanism can fix the double-sided adhesive tape unwound by the adhesive tape unwinding mechanism to prevent the double-sided adhesive tape from sliding.

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0048] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0049] The present embodiment provides an automatic roll changing device 10, which solves the problem in the prior art that manual glue preparation leads to reduced machine efficiency and increased labor costs.

[0050] See also Figure 1 and Figure 2 , Figure 1 The three-dimensional structure of the automatic roll changing device 10 in this embodiment at a first viewing angle is shown. Figure 2 The three-dimensional structure of the automatic roll changing device 10 in this embodiment at a second viewing angle is shown.

[0051] The automatic roll changing device 10 comprises a first mounting plate 11, a first unwinding mechanism 12, a second unwinding mechanism 13, a tape splicing mechanism 14 and an automatic glue preparation mechanism 20. The first unwinding mechanism 12, the second unwinding mechanism 13 and the tape splicing mechanism 14 are arranged on the first mounting plate 11.

[0052] The automatic glue preparation mechanism 20 is disposed on the first mounting plate 11 , and is used to prepare double-sided adhesive tape on the material tape unwound by the first unwinding mechanism 12 and / or the second unwinding mechanism 13 .

[0053] The tape splicing mechanism 14 is used to splice the tape unwound by the first unwinding mechanism 12 and the tape unwound by the second unwinding mechanism 13 .

[0054] Among them, the above-mentioned embodiment provides an automatic roll-changing device 10 that can automatically complete the preparation of glue and the splicing of tapes. The first mounting plate 11, the first unwinding mechanism 12, the second unwinding mechanism 13, the splicing mechanism 14 and the automatic glue preparation mechanism 20 are all arranged on the first mounting plate 11. The first unwinding mechanism 12 and the second unwinding mechanism 13 are used to unwind new tapes and old tapes. Before the new and old tapes are spliced ​​by the splicing mechanism 14, the double-sided adhesive tape and the release paper will be separated by the automatic glue preparation mechanism 20, and a section of adhesive tape will be attached to the tape unwound by the first unwinding mechanism 12 and / or the second unwinding mechanism 13, and then the new and old tapes will be spliced ​​by the automatic splicing mechanism 14. Since the glue preparation work of the double-sided adhesive tape can be completed by the automatic glue preparation mechanism 20, it can improve production efficiency and reduce labor costs.

[0055] It should be noted that, in this embodiment, see Figure 1 and Figure 2 , the automatic glue preparation mechanism 20 is arranged corresponding to the first unwinding mechanism 12, and the automatic glue preparation mechanism 20 is used to prepare the double-sided adhesive tape on the material tape unwinding by the first unwinding mechanism 12. In other specific embodiments, the automatic glue preparation mechanism 20 moves on the first mounting plate 11 to correspond to the first unwinding mechanism 12 and the second unwinding mechanism 13; or, the automatic glue preparation mechanism 20 is arranged corresponding to the second unwinding mechanism 13, and the automatic glue preparation mechanism 20 is used to prepare the double-sided adhesive tape on the material tape unwinding by the second unwinding mechanism 13.

[0056] See also Figure 3 , Figure 4 , Figure 5 as well as Figure 6 , Figure 3 The specific structure of the automatic glue preparation mechanism 20 in this embodiment at a first viewing angle is shown. Figure 4 The specific structure of the automatic glue preparation mechanism 20 in this embodiment at a second viewing angle is shown. Figure 5 The specific structure of the automatic glue preparation mechanism 20 in this embodiment is shown in the third viewing angle. Figure 6 The specific structure of the automatic glue preparation mechanism 20 in this embodiment at a fourth viewing angle is shown.

[0057] The automatic glue preparation mechanism 20 includes a first driving mechanism 21, a second mounting plate 22, a glue paper unwinding mechanism 23, a release paper winding mechanism 24 and a glue stripping block 25. The release paper winding mechanism 24 and the glue stripping block 25 are installed on the second mounting plate 22. The double-sided adhesive is wound around the glue stripping block 25. The glue stripping block 25 is used to bond the double-sided adhesive to the material tape. The first driving mechanism 21 is used to drive the second mounting plate 22 to move.

[0058] It should be noted that, in this embodiment, the first driving mechanism 21 is used to drive the second mounting plate 22 to move in a first direction and a second direction perpendicular to each other. In one possible implementation, the first direction is a vertical direction, so that the stripping block 25 located vertically above the material belt can move in the first direction, thereby abutting against the material belt and moving away from the material belt. The second direction is the glue pulling direction, which means that when the stripping block 25 presses the double-sided adhesive tape against the material belt, the stripping block moves in this direction, so that a section of the adhesive tape can be adhered to the material belt.

[0059] The first driving mechanism 21 includes a first driving portion 210 , a second driving portion 211 and a third mounting plate 212 .

[0060] The first driving portion 210 is disposed on the first mounting plate 11 , and is used to drive the third mounting plate 212 to move along a first direction relative to the first mounting plate 11 .

[0061] The second driving portion 211 is disposed on the third mounting plate 212 , and is used to drive the second mounting plate 212 to move relative to the third mounting plate 212 along the second direction.

[0062] See also Figure 3 as well as Figure 7 , Figure 7 for Figure 2 Enlarged view of point VII in the middle.

[0063] The first driving unit 210 drives the third mounting plate 212 to move in the first direction relative to the first mounting plate 11, and the second driving unit 211 is disposed on the third mounting plate 212, and drives the second mounting plate 22 to move in the second direction relative to the third mounting plate 212. The release paper winding mechanism 24 and the adhesive stripping block 25 are disposed on the second mounting plate 22. Therefore, by driving the first driving unit 210 and the second driving unit 211, the release paper winding mechanism 24 and the adhesive stripping block 25 can move in the first direction and the second direction, so as to achieve abutment with the material strip and complete the adhesive pulling action.

[0064] The adhesive tape unwinding mechanism 23 and the release paper winding mechanism 24 are used for unwinding and winding the double-sided adhesive tape. Among them, by driving the first driving unit 210, the adhesive stripping block 25 can be pressed against the material belt, and the adhesive tape of the double-sided adhesive tape is attached to the material belt. By driving the second driving unit 211, the adhesive stripping block 25 moves to pull the adhesive, so that a section of the adhesive tape is adhered to a part of the material belt. The release paper of the double-sided adhesive tape is wound by the release paper winding mechanism 24. By driving the first driving mechanism 21, the adhesive stripping block 25 can be moved away from the material belt, stopping the adhesive tape's bonding action or pulling the adhesive tape off.

[0065] Among them, a possible specific working process is provided:

[0066] Currently, the stripping block 25 is in Figure 7 Above point B in the middle.

[0067] The second driving unit 211 drives the second mounting plate 22 to move in the second direction, so that the stripping block 25 is located at Figure 7 Above point A (where Figure 7 The positions A and B in the figure are exemplary marks to clearly describe the movement direction of the stripping block 25. The first driving unit 210 drives the third mounting plate 212 to move in the first direction, so that the stripping block 25 moves downward and abuts against the material belt. The abutment point can be regarded as Figure 7 At point A, the double-sided adhesive tape will adhere to the position A of the material strip. The release paper rewinding mechanism 24 rewinds, and the release paper and the adhesive tape will separate. At the same time, the second mounting plate 22 returns, that is, the stripping block 25 moves from point A to point B. At this time, a section of adhesive tape has been flatly adhered to the material strip. The first driving unit 210 drives the third mounting plate 212 to move in the first direction, so that the third mounting plate 212 moves upward. The stripping block 25 moves away from the material strip, stops the adhesive tape from adhering or tears off the adhesive tape.

[0068] It should be noted that, please refer to Figure 3 The stripping block 25 is a block structure with a conical head. The double-sided tape will pass through the conical head of the stripping block 25, and the conical head of the stripping block 25 will abut against the surface of the release paper of the double-sided tape. Since the stripping block 25 is tilted downward, the double-sided tape will bend, and the bent part of the double-sided tape will abut against the surface of the material tape as the stripping block 25 abuts, so that the adhesive paper of the double-sided tape will adhere to the material tape. After the adhesive paper is adhered to the material tape, the release paper will be separated from the adhesive paper under the winding action of the release paper winding mechanism 24 and will be recovered by the release paper winding mechanism 24.

[0069] It should be noted that, in this embodiment, the adhesive tape unwinding mechanism 23 is disposed on the first mounting plate 11. In other specific implementations, the adhesive tape unwinding mechanism 23 may also be disposed on the second mounting plate 22.

[0070] It should be noted that in this embodiment, the first driving part 210 is a cylinder fixed on the first mounting plate 11, and its telescopic rod is connected to the third mounting plate 212. The second driving part 211 is a cylinder fixed on the third mounting plate 212, and its telescopic rod is connected to the second mounting plate 22.

[0071] It should be noted that if Figure 2 and Figure 5The release paper rewinding mechanism 24 includes a motor 240, which is disposed on the second mounting plate 22 and provides power for the release paper rewinding mechanism 24 to rewind the release paper. In one possible implementation, after the adhesive stripping block 25 moves downward and abuts against the material belt, the motor 240 starts to work, and the release paper rewinding mechanism 24 starts to rewind, which pulls the double-sided adhesive tape, so that the second mounting plate 22 returns to its original position.

[0072] Alternatively, in one possible implementation, see Figure 3 , Figure 4 and Figure 6 .

[0073] A guide rail 2120 extending along the second direction is disposed on the third mounting plate 212 , and the second mounting plate 22 is disposed on the guide rail 2120 .

[0074] In the above embodiment, a technical solution is provided in which the second mounting plate 22 can stably slide on the third mounting plate 212 through the guide rail 2120. The second mounting plate 22 can stably move in the second direction relative to the third mounting plate 212 through the driving of the second driving part 211 and the guiding of the guide rail 2120.

[0075] There are two guide rails 2120 , which are spaced apart on the third mounting plate 212 in the first direction. The second mounting plate 22 cooperates with the two guide rails 2120 , thereby stably moving on the third mounting plate 212 in the second direction.

[0076] See also Figure 3 The automatic glue preparation mechanism 20 also includes a roller group 26 , which is mounted on the second mounting plate 22 , and the double-sided adhesive passes through the roller group 26 and the glue stripping block 25 .

[0077] The roller group 26 is located between the adhesive paper unwinding mechanism 23 and the release paper winding mechanism 24 to provide tension for the unwinding and winding of the double-sided adhesive.

[0078] The roller group 26 includes a first roller 260 located upstream of the stripping block 25 and a second roller 261 located downstream of the stripping block 25. The first roller 260 is located on the third mounting plate 212, and the second roller 261 is located on the second mounting plate 22.

[0079] The automatic glue preparation mechanism 20 further includes a double-sided glue fixing mechanism 27 . The double-sided glue fixing mechanism 27 is disposed on the second mounting plate 22 and is used to cooperate with the first roller 260 to compress or loosen the double-sided glue.

[0080] Among them, the double-sided tape fixing mechanism 27 includes a double-sided tape fixing driving cylinder 270 and a double-sided tape fixing block 271. The double-sided tape fixing driving cylinder 270 is fixed on the second mounting plate 22, and the telescopic rod of the double-sided tape fixing driving cylinder 270 drives the double-sided tape fixing block 271 to move.

[0081] After the adhesive tape is adhered to the material tape, when the double-sided tape needs to be torn off, the double-sided tape fixing driving cylinder 270 will drive the double-sided tape fixing block 271 to lean against the first roller to press the double-sided tape, and then drive the third mounting plate 212 to rise through the first driving part 210, thereby tearing off the adhesive tape.

[0082] See also Figure 3 The automatic glue preparation mechanism 20 also includes a tape cutting mechanism 28, which is disposed on the second mounting plate 22 and is used to cut the tape of the double-sided adhesive or to form a cut on the tape.

[0083] The adhesive tape cutting mechanism 28 includes an adhesive tape cutting cylinder 280 and an adhesive tape cutter 281 . The adhesive tape cutting cylinder 280 is fixed to the second mounting plate 22 . The adhesive tape cutter 281 is fixed to the telescopic rod of the adhesive tape cutting cylinder 280 and is close to the adhesive stripping block 25 .

[0084] After the adhesive is pulled, that is, after the adhesive stripping block 25 abuts against the material strip and moves from point A to point B, the adhesive tape cutting mechanism 28 drives the adhesive tape cutter 281 to move downward, so that the adhesive tape cutter 281 creates a cut mark on the adhesive tape. At the same time or subsequently, the double-sided adhesive fixing drive cylinder 270 drives the double-sided adhesive fixing block 271 to abut against the first roller 260 to compress the double-sided adhesive, and then drives the first driving unit 210 to make the third mounting plate 212 rise, thereby easily tearing off the adhesive tape.

[0085] It should be noted that in other embodiments, after the stripping block 25 abuts against the material strip and moves from point A to point B, the adhesive tape cutting mechanism 28 drives the adhesive tape cutter 281 to move downward, so that the adhesive tape cutter 281 cuts the adhesive tape, and then drives the first driving unit 210 to cause the third mounting plate 212 to rise.

[0086] In order to ensure that the material strip is in a stable state when preparing the glue, and to prevent the strip from being displaced due to the movement of the strip strip strip strip strip strip strip strip strip strip strips on the strip strip surface, thereby causing uneven glue preparation, the automatic glue preparation mechanism 20 also includes a strip strip fixing assembly 29, which is mounted on the third mounting plate 212, and is used to tighten or loosen the strip strip.

[0087] The automatic roll-changing device 10 includes a support member 15 , which is used to thread the material strip unwound by the first unwinding mechanism 12 . The support member 15 includes a support seat 150 arranged on the first mounting plate 11 and a roller 151 installed on the support seat 150 .

[0088] Among them, see Figure 3 and Figure 7 The material strip fixing assembly 29 of the automatic glue preparation mechanism 20 includes a material strip fixing driving unit 290 and a fixed pressing block 291. The fixed pressing block 291 has an arc surface corresponding to the contour of the roller 151 on the support seat 150. The material strip fixing driving unit 290 drives the fixed pressing block 291 to abut against the roller 151 on the support seat 150 to press the material strip on the roller 151 of the support seat 150. At the same time, the automatic glue preparation mechanism 20 will also prepare glue for the material strip on the roller 151 of the support seat 150.

[0089] Please see again Figure 1 and Figure 2 The belt connecting mechanism 14 includes a belt connecting pressing block 140 , a belt threading member 141 and a belt connecting driving unit 142 .

[0090] The tape pressing block 140 is slidably disposed on the first mounting plate 11 and is used to act on the tape unwound by the first unwinding mechanism 12 .

[0091] The tape threading member 141 is disposed on the first mounting plate 11 , and is used for threading the tape unwound by the second unwinding mechanism 13 .

[0092] The tape connection driving unit 142 is disposed on the first mounting plate 11 and drives the tape connection pressing block 140 to slide so that the tape unwound by the first unwinding mechanism 12 is pressed against the tape on the tape threading member 141 .

[0093] The tape threading member 141 includes a tape threading seat 1410 and a roller 1411 installed on the tape threading seat 1410. The tape connection driving unit 142 is a cylinder arranged on the first mounting plate 11, and the telescopic rod of the cylinder is connected to the tape connection pressing block 140. The tape threading member 141 is adjacent to the second unwinding mechanism 13. The tape connection pressing block 140 is located at one end of the support seat 150 close to the tape threading seat 1410.

[0094] The tape unwound by the second unwinding mechanism 13 will be passed through the roller 1411 on the tape threading seat 1410, and the tape unwound by the first unwinding mechanism will be passed through the roller 151 on the support seat 150. When it is necessary to splice the tape, a portion of the tape unwound by the first unwinding mechanism 12 will be unwound, so that the portion of the tape that has been prepared with glue by the automatic glue preparation mechanism 20 is on the splicing pressure block 140, and the splicing drive unit 142 drives the splicing pressure block 140, so that the tape with the adhesive tape is pushed to the tape on the tape threading member 141, thereby completing the splicing.

[0095] It should be noted that, in order to ensure that the material strip has sufficient tension for strip threading and strip splicing, a plurality of tension rollers 30 are further included downstream of the strip splicing mechanism 14 .

[0096] See also Figure 2The automatic roll changing device 10 also includes a first cutting mechanism 16 .

[0097] The first cutting mechanism 16 is slidably disposed on the first mounting plate 11 .

[0098] The first cutting mechanism 16 has a first position for cutting the old material strip unwound by the first unwinding mechanism 12 .

[0099] The first cutting mechanism 16 has a second position for clamping and cutting the new material strip unwound by the first unwinding mechanism 12 .

[0100] It should be noted that the first cutting mechanism 16 has the functions of cutting and fixing. Since the position of the first cutting mechanism 16 relative to the first mounting plate 11 is variable, when the first cutting mechanism 16 is in the first position, it can be used to cut the old material tape unwound by the first unwinding mechanism 12; when the first cutting mechanism 16 is in the second position, it can be used to clamp and cut the new material tape unwound by the first unwinding mechanism 12 (the end of the new material tape is the waste end and needs to be cut off).

[0101] Among them, see Figure 8 , Figure 8 for Figure 2 Enlarged view of point VIII in the middle.

[0102] The first mounting plate 11 is provided with a clamping seat 11a, and a cutout groove 80 for old material is provided on the lower surface of the clamping seat 11a. The material strip unwound by the first unwinding mechanism 12 will pass through the lower surface of the clamping seat 11a and then pass through the roller on the support seat 150. A cutout groove 81 for new material is provided on the lower surface of the support seat 150.

[0103] The first cutting mechanism 16 includes a moving cylinder 160 and a first cutting body 161. The moving cylinder 160 is fixed to the first mounting plate 11. The first cutting body 161 can slide relative to the first mounting plate 11. The moving cylinder 160 drives the first cutting body 161 to move. Among them, the first cutting body 161 includes a first cylinder 1610, a first abutment block 1611 and a first cutter 1612 located on the first abutment block 1611. The first cylinder 1610 drives the first abutment block 1611 to move to perform the fixing and cutting actions. Among them, the first abutment block 1611 can be deformed so that the first cutter 1612 can enter the new material cutting groove 81 on the lower surface of the support seat 150 to cut the material strip.

[0104] When the first unwinding mechanism 12 unwinds the old material tape, the function of the first cutting body 161 is to cut off the old material tape after the old and new material tapes are connected. The moving cylinder 160 will drive the first cutting body 161 to the first position, that is, below the clamping seat 11a. The first cylinder 1610 will drive the first cutter 1612 to move to the old material cutting groove 80 on the lower surface of the clamping seat 11a, thereby cutting off the old material tape.

[0105] When the first unwinding mechanism 12 unwinds the new material tape, the function of the first cutting body 161 is to fix the new material tape and cut off the waste material at the front end of the new material tape before the new and old material tapes are connected. The moving cylinder 160 will drive the first cutting body 161 to the second position, that is, below the support seat 150. The first cylinder 1610 will drive the first cutter 1612 and the first abutment block 1611 to move to the lower surface of the support seat 150, thereby cutting off the waste material at the front end of the new material tape and fixing the new material tape. When connecting the tapes, the first cylinder 1610 will retreat to allow the first abutment block 1611 to release the new material tape.

[0106] See also Figure 1 and Figure 2 The automatic roll changing device 10 further includes a second cutting mechanism 17 and a clamping mechanism 18 .

[0107] The second cutting mechanism 17 is used to cut the old material strip unwound by the second unwinding mechanism 13 .

[0108] The clamping mechanism 18 is used to clamp and cut the new material strip unwound by the second unwinding mechanism 13 .

[0109] The second cutting mechanism 17 includes a second cylinder 170 and a second scrap cutter 171. The second cylinder 170 is fixed on the first mounting plate 11 and drives the second scrap cutter 171. The second scrap cutter 171 is used to cut the tape between the second unwinding mechanism 13 and the tape threading member 141. When the second unwinding mechanism 13 unwinds the scrap tape and the tape connection is completed, the second cylinder 170 drives the second scrap cutter 171 to cut the scrap tape. In order to enable the second scrap cutter 171 to accurately cut the scrap tape, a roller 172 is provided between the tape threading member 141 and the second unwinding mechanism 13 to provide tension to the tape, so that the second scrap cutter 171 can smoothly cut the scrap tape.

[0110] The clamping mechanism 18 includes a third cylinder 180, a second abutment block 181 and a second new material cutter 182, wherein the second new material cutter 182 is located in the second abutment block 181. A new material cutting groove 81 is formed on the bottom surface of the tape threading seat 1410. The second abutment block 181 can be deformed so that the second new material cutter 182 can enter the new material cutting groove 81 on the bottom surface of the tape threading seat 1410 to cut the tape.

[0111] When the second unwinding mechanism 13 unwinds the new material tape, the third cylinder 180 drives the second abutment block 181 and the second new material cutter 182 to move to the lower surface of the tape threading seat 1410, thereby cutting off the waste material at the front end of the new material tape and fixing the new material tape. When connecting the tape, the third cylinder 180 will retreat to allow the second abutment block 181 to release the new material tape.

[0112] It should be noted that two waste collection boxes 40 are provided on the first mounting plate 11 , and the two waste collection boxes 40 are used to collect waste from the new material strip cut by the first cutting mechanism 16 and waste from the new material strip cut by the clamping mechanism 18 , respectively.
