Description

Technical Field

[0001] The invention belongs to the technical field of battery cell pretreatment lines, and in particular relates to a silicone stripping device, silicone pasting equipment and a battery cell pretreatment line. Background Art

[0002] In the manufacturing process of battery modules, the battery cell pre-processing line is required to test, clean and apply silicone sheets to the battery cells. Among them, the silicone sheet mainly serves to isolate two adjacent battery cells.

[0003] When sticking the silicone sheet, the incoming material is a silicone composite tape, which includes a stacked release film, a silicone sheet and a base film, wherein multiple silicone sheets are adhered between the release film and the base film. The release film is peeled off by a silicone peeling device so that the silicone sheet to be stuck is only stuck on the base film. The silicone sheet to be stuck is taken out from the base film by a clamp and is stuck to the battery cell.

[0004] However, when making silicone composite tape, multiple silicone sheets are cut out in advance by die cutting, and then the multiple silicone sheets are placed on the base film in sequence, and finally the release film is attached to the base film, so that each silicone sheet is attached between the base film and the release film, resulting in a more complicated production process of the silicone composite tape and a lower production efficiency of the silicone composite tape. Moreover, since the size of the silicone sheet is fixed, the silicone composite tape is only compatible with one type of battery cell, resulting in poor adaptability of the silicone composite tape.

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of them.

[0050] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Embodiment 1:

[0052] Please see attached Figures 1 to 7 The silicone peeling device 10a of the present invention includes a material discharge mechanism 100, a material receiving mechanism 200 and a cutting mechanism 300.

[0053] Among them, the unwinding mechanism 100 includes a mounting plate 110, an unwinding roller 120, a feed roller group 130, a first winding roller 140, a second winding roller 150 and a peeling blade 160. The unwinding roller 120, the feed roller group 130, the first winding roller 140 and the second winding roller 150 are all rotatably connected to the mounting plate 110. The unwinding roller 120, the feed roller group 130, the first winding roller 140 and the second winding roller 150 are parallel to each other. The peeling blade 160 is fixedly connected to the mounting plate 110. The first winding roller 140 and the second winding roller 150 are respectively located on the upper and lower sides of the peeling blade 160.

[0054] The unwinding roller 120 is used to unwind the silicone composite tape, the stripping blade 160 is used to strip the base film and the release film, the first winding roller 140 is used to roll up the release film, and the second winding roller 150 is used to roll up the base film. It can be understood that the silicone composite tape includes a release film, a silicone tape and a base film that are stacked, that is, one side of the silicone tape is attached to the base film, and the other side of the silicone tape is attached to the release film. The silicone composite tape is led out from the unwinding roller 120, the silicone composite tape is passed through the feed roller group 130, the base film is wound around the stripping blade 160 and folded back to the second winding roller 150, and the release film tears off the silicone tape on the stripping blade 160 and is rolled up on the first winding roller 140.

[0055] Furthermore, the receiving mechanism 200 is disposed adjacent to the mounting plate 110, and a cutting channel 101 is formed between the receiving mechanism 200 and the blade of the stripping blade 160. The receiving mechanism 200 is used to receive the silicone, and the received silicone is the portion of the silicone tape extending from the stripping blade 160. The cutting mechanism 300 is mounted on the mounting plate 110, and the cutting mechanism 300 is used to cut the silicone along the cutting channel 101 to cut out a silicone sheet, so that a silicone sheet is placed on the receiving mechanism 200.

[0056] In this embodiment, when the silicone stripping device 10a is working, the unwinding roller unwinds the silicone composite tape, the first winding roller 140 winds up the release film, and the second winding roller 150 winds up the base film, so that the stripping blade 160 strips off part of the silicone, and the stripped silicone extends out of the stripping blade 160, the receiving mechanism 200 receives the stripped silicone, and the cutting mechanism 300 cuts the silicone along the cutting channel 101 to cut out a silicone sheet, and the silicone sheet is placed on the receiving mechanism 200.

[0057] The silicone stripping device 10a provided by the present invention, after the stripping blade 160 strips the silicone, the stripped silicone extends out of the stripping blade 160, the receiving mechanism 200 receives the extended silicone, and a cutting channel 101 is formed between the receiving mechanism 200 and the stripping blade 160, the cutting mechanism 300 cuts the silicone along the cutting channel 101 to cut out a silicone sheet, and the silicone sheet is placed on the receiving mechanism 200, so that the silicone stripping device 10a can cut the silicone after stripping the silicone to obtain a silicone sheet, and there is no need to cut the silicone and place multiple silicone sheets when making the silicone composite tape, which simplifies the production process of the silicone composite tape and improves the production efficiency of the silicone composite tape. In addition, by adjusting the length of the silicone stripped each time, that is, adjusting the length of the silicone extending out of the stripping blade 160, the size of the cut silicone sheet can be adjusted so that the silicone sheet is compatible with the battery cell, so that the silicone composite tape can be compatible with a variety of battery cells, and the adaptability of the silicone composite tape is improved.

[0058] Furthermore, by cutting the silicone through the cutting mechanism, the silicone sheet is avoided from being cut out through die cutting, thereby avoiding the problem of silicone waste being generated and improving the utilization rate of the silicone.

[0059] In some preferred embodiments, the cutting mechanism 300 includes a mounting frame 300a, a pressing sub-mechanism 300b and a slitting sub-mechanism 300c. The mounting frame 300a is fixedly connected to the mounting plate 110, the pressing sub-mechanism 300b is mounted on the mounting frame 300a, and the number of the pressing sub-mechanisms 300b is two, namely, a first pressing sub-mechanism 300b1 and a second pressing sub-mechanism 300b2. The first pressing sub-mechanism 300b1 is located on the upper side of the stripping blade 160 and is used to press the silicone on the stripping blade 160, and the second pressing sub-mechanism 300b2 is located on the upper side of the material receiving mechanism 200 and is used to press the silicone on the material receiving mechanism 200, so that the silicone on both sides of the cutting channel 101 is pressed. The slitting sub-mechanism 300c is installed on the mounting frame 300a and is located between the two pressing sub-mechanisms 300b, and is used to cut the silicone along the cutting channel 101. In this embodiment, since the silicone on both sides of the cutting channel 101 are respectively pressed by two pressing sub-mechanisms 300b, that is, the two sides of the silicone cutting point are respectively pressed by two pressing sub-mechanisms 300b, the position stability of the silicone cutting point is improved, ensuring that the slitting sub-mechanism 300c can smoothly cut the silicone tape.

[0060] In some preferred embodiments, the slitting sub-mechanism 300c includes a slitting drive assembly 330 and a silicone cutting assembly 340. The slitting drive assembly 330 is mounted on the mounting frame 300a. The silicone cutting assembly 340 is connected to the power output end of the slitting drive assembly 330. The slitting drive assembly 330 is used to drive the silicone cutting assembly 340 to move so that the silicone cutting assembly 340 is used to cut the silicone along the cutting channel 101. It can be understood that the slitting drive assembly 330 can be a screw motor, an electric push rod or other existing linear drive assemblies.

[0061] In some preferred embodiments, the mounting frame 300a is provided with a cutting guide groove 301, a transition groove 302 and a reset groove 303. The first end of the cutting guide groove 301 is connected to the reset groove 303 through the transition groove 302. The cutting guide groove 301 is located between the reset groove 303 and the stripping blade 160, that is, the cutting guide groove 301 is closer to the stripping blade 160 than the reset groove 303. In this embodiment, the cutting guide groove 301 is horizontally extended. Of course, in some other embodiments, the extension direction of the cutting guide groove 301 may also be inclined to the horizontal line and the vertical direction.

[0062] Furthermore, the silicone cutting assembly 340 includes a lifting rail 341, a cutting tool 342 and a guide 343, wherein the lifting rail 341 is fixedly connected to the power output end of the slitting drive assembly 330, and the slitting drive assembly 330 is used to drive the lifting rail 341 to translate. The cutting tool 342 is slidably connected to the lifting rail 341, and the cutting tool 342 can be lifted and lowered along the lifting rail 341. The guide 343 protrudes and is connected to the cutting tool 342. The guide 343 is movably arranged in the cutting guide groove 301, the transition groove 302 and the reset groove 303. When cutting the silicone, the guide 343 moves from the reset groove 303 to the second end of the cutting guide groove 301, and after cutting the silicone, the guide 343 moves from the second end of the cutting guide groove 301 to the reset groove 303.

[0063] In this embodiment, when cutting the silicone, the slitting drive assembly 330 drives the lifting guide rail 341 to move, so that the guide member 343 moves from the reset groove 303 to the first end of the cutting guide groove 301. At this time, the cutting tool 342 moves downward along the lifting guide rail 341. As the lifting guide rail 341 continues to move, the guide member 343 moves from the first end of the cutting guide groove 301 to the second end of the cutting guide groove 301. At this time, the cutting tool 342 cuts the silicone along the cutting channel 101. After the silicone is cut, the slitting drive assembly 330 drives the lifting guide rail 341 to move in the opposite direction, so that the guide member 343 moves from the second end of the cutting guide groove 301 to the first end of the cutting guide groove 301. At this time, the cutting tool 342 is reset along the cutting channel 101. As the lifting guide rail 341 continues to move in the opposite direction, the guide member 343 moves from the first end of the cutting guide groove 301 to the reset groove 303. At this time, the cutting tool 342 moves upward along the lifting guide rail 341, so that the cutting tool 342 and the stripping blade 160 are offset in the horizontal direction to avoid interference between the cutting tool 342 and the moving structure below the stripping blade 160.

[0064] In some preferred embodiments, the guide member 343 is rotatably connected to the cutting tool 342, and the guide member 343 is rollingly connected to the cutting guide groove 301, the transition groove 302 and the reset groove 303, which reduces the wear of the guide member 343 and improves the smoothness of movement of the guide member 343, thereby improving the smoothness of movement of the cutting tool 342.

[0065] In some preferred embodiments, the cutting tool 342 includes a lifting slider 342a, a tool connection seat 342b and a cutting blade 342c, the lifting slider 342a is slidably connected to the lifting guide rail 341, the tool connection seat 342b is fixedly connected to the lifting slider 342a, one end of the cutting blade 342c is fixedly connected to the tool connection seat 342b, the other end of the cutting blade 342c protrudes from the lower side of the tool connection seat 342b, the cutting blade 342c cuts the silicone along the cutting channel 101, and the guide 343 protrudes and is connected to the tool connection seat 342b. In this embodiment, the lifting slider 342a is slidably connected to the lifting guide rail 341, which improves the smoothness of the up and down movement of the cutting tool 342, thereby improving the smoothness of the grooving operation of the cutting tool 342.

[0066] Furthermore, the cutting blade 342c is parallel to the extending direction of the cutting channel 101, and the end of the cutting blade 342c away from the tool connection seat 342b has two cutting edges 3421, and the two cutting edges 3421 intersect and form a blade tip. In this embodiment, one of the cutting edges 3421 is used to cut silicone. When the cutting edge 3421 is damaged during use, the position of the cutting blade 342c is adjusted so that the other cutting edge 3421 is used to cut silicone, thereby extending the service life of the cutting blade 342c.

[0067] In some preferred embodiments, an installation area 304 is formed inside the installation frame 300a, and the silicone cutting component 340 is inserted into the installation area 304, so that the installation frame 300a is arranged around the cutting tool 342, thereby enabling the installation frame 300a to protect the silicone cutting component 340.

[0068] In some preferred embodiments, the slitting sub-mechanism 300c also includes a translation guide assembly 350, which is horizontally arranged, and the silicone cutting assembly 340 is slidably connected to the translation guide assembly 350, so that the translation guide assembly 350 guides the translation of the silicone cutting assembly 340, thereby improving the smoothness of the translation of the silicone cutting assembly 340, and further improving the smoothness of the cutting operation.

[0069] In some preferred embodiments, the clamping sub-mechanism 300b includes a clamping drive assembly 310 and an abutment assembly 320. The clamping drive assembly 310 is installed on the mounting frame 300a, and the abutment assembly 320 is connected to the power output end of the clamping drive assembly 310. The clamping drive assembly 310 drives the abutment assembly 320 to clamp the silicone before cutting off the silicone. The clamping drive assembly 310 drives the abutment assembly 320 to loosen the silicone after cutting off the silicone, thereby improving the position stability of the silicone cut-off point.

[0070] In some preferred embodiments, the material receiving mechanism 200 includes a material receiving component 200a and a removal drive component 200b, a cutting channel 101 is formed between the material receiving component 200a and the blade of the stripping blade 160, the material receiving mechanism 200 is used to receive the silicone, the power output end of the removal drive component 200b is connected to the material receiving component 200a, and the removal drive component 200b is used to drive the material receiving component 200a to move horizontally, so that the material receiving component 200a leaves the material receiving position, thereby improving the convenience of taking away the silicone sheet from the material receiving component 200a. It can be understood that before cutting off the silicone, if the material receiving component 200a is not in the material receiving position, the removal drive component 200b drives the material receiving component 200a to make the material receiving component 200a located at the material receiving position, thereby enabling the material receiving component 200a to receive the material normally.

[0071] In some preferred embodiments, there are multiple material receiving components 200a, each material receiving component 200a includes a lifting drive component 210 and a material receiving plate 220, the lifting drive component 210 of each material receiving component 200a is installed at the power output end of the removal drive component 200b, and the material receiving plate 220 of each material receiving component 200a is fixedly connected to the power output end of the corresponding lifting drive component 210.

[0072] In this embodiment, multiple material receiving components 200a receive materials in sequence. Specifically, when receiving materials, all the material receiving plates 220 are located at the highest point, and the removal drive component 200b drives the multiple material receiving components 200a to move synchronously, so that the material receiving plate 220 of one of the material receiving components 200a and the blade of the stripping blade 160 form a cutting channel 101 together, and the material receiving plate 220 of the material receiving component 200a receives the silicone; after the silicone on the material receiving plate 220 of the material receiving component 200a is cut off, the lifting drive member 210 of the material receiving component 200a drives the corresponding material receiving plate 220 to descend, so that the material receiving plate 220 of the material receiving component 200a leaves the receiving channel 101. Then, the stripping blade 160 continues to strip the silicone, and the removal drive assembly 200b drives the multiple material receiving assemblies 200a to move synchronously again, so that the material receiving plate 220 of the next material receiving assembly 200a and the blade of the stripping blade 160 jointly form a cutting channel 101, and the material receiving plate 220 of the material receiving assembly 200a receives the silicone. After the silicone on the material receiving plate 220 of the material receiving assembly 200a is cut off, the lifting drive member 210 of the material receiving assembly 200a drives the corresponding material receiving plate 220 to descend, so that the material receiving plate 220 of the material receiving assembly 200a leaves the material receiving position. When all the material receiving assemblies 200a have completed the material receiving, the removal drive assembly 200b drives each material receiving assembly 200a to leave the material receiving position, and each material receiving assembly 200a is staggered with the material discharge mechanism 100 and the cutting mechanism 300 in the vertical direction. At this time, the silicone sheets on the multiple material receiving plates 220 are at the same height. In this way, by moving out the cooperation of the drive assembly 200b and the lifting drive component 210, the material receiving mechanism 200 can receive multiple silicone sheets and make the multiple silicone sheets at the same height, so that the multiple silicone sheets can be taken away at the same time and pasted onto the battery cell, thereby improving the convenience and efficiency of silicone pasting.

[0073] It is understandable that when the receiving plate 220 moves faster, the silicone sheet will slide off the receiving plate 220 more easily, resulting in failure of subsequent silicone application.

[0074] In order to avoid the problem of silicone sheets slipping off, in some preferred embodiments, a negative pressure hole 221 is formed inside the receiving plate 220, and a plurality of adsorption holes 222 arranged at intervals are opened on the upper side of the receiving plate 220, and each adsorption hole 222 is connected to the negative pressure hole 221. In this embodiment, when the receiving plate 220 receives the silicone, the negative pressure hole 221 is sucked by the external negative pressure system, so that each adsorption hole 222 forms a negative pressure and adsorbs the silicone, thereby improving the position stability of the silicone and further improving the position stability of the silicone cut-off point. In addition, after the silicone is cut off, each adsorption hole 222 adsorbs the silicone sheet through negative pressure, thereby avoiding the problem of the silicone sheet slipping off when the receiving plate 220 moves, and ensuring the normal progress of the subsequent silicone sticking operation.

[0075] It can be understood that the flexibility of silicone is relatively strong. When the adsorption force on the receiving plate 220 is relatively large, it will cause part of the silicone to be embedded in the adsorption hole 222, causing the silicone to be offset, resulting in poor dimensional accuracy of the cut silicone sheet, and more serious offset of the cut silicone sheet, resulting in a greater risk of failure of the adsorption adhesive device 10b to take the material from the receiving plate 220. Therefore, the adsorption force on the receiving plate 220 needs to be relatively small. Since the adsorption force on the receiving plate 220 is relatively small, the cutting speed of the cutting mechanism 300 needs to be relatively small to avoid the cutting mechanism 300 pushing the silicone on the receiving plate 220 to be significantly offset during the cutting process. In this way, the cutting efficiency of the cutting mechanism 300 still has room for improvement.

[0076] In order to improve the working efficiency of the cutting mechanism 300, in some preferred embodiments, the material receiving component 200a also includes a positioning blade group 230, and the positioning blade group 230 is in a criss-cross mesh shape. The positioning blade group 230 is formed with a criss-cross positioning blade group 231, and the positioning blade group 231 is in a criss-cross mesh shape. An embedding groove 223 is provided on the upper surface of the material receiving plate 220, and the embedding groove 223 is staggered with the adsorption hole 222. The embedding groove 223 is adapted to the positioning blade group 230, and the positioning blade group 230 is embedded in the embedding groove 223, and the positioning blade group 231 protrudes from the upper side of the material receiving plate 220, and the positioning blade group 231 cuts into the silicone when the material receiving plate 220 receives the silicone. In this embodiment, since the positioning blade set 231 cuts into the silicone, the positioning blade set 230 limits the silicone, thereby improving the position stability of the silicone, thereby making the cutting speed of the cutting mechanism 300 higher, improving the cutting efficiency of the cutting mechanism 300, and thereby improving the manufacturing efficiency of the battery module. Moreover, since the positioning blade set 231 cuts into the silicone, and the positioning blade set 231 is in a criss-cross mesh, a mesh-like anti-skid pattern is formed on the lower surface of the silicone, increasing the roughness of the lower surface of the silicone sheet, that is, increasing the roughness of the bonding surface of the silicone sheet, making the friction between the silicone sheet and the battery cell larger, and improving the position stability of the silicone sheet on the battery cell.

[0077] Further, the positioning blade group 230 includes a plurality of transverse positioning blades 230a and a plurality of longitudinal positioning blades 230b, wherein the plurality of transverse positioning blades 230a are arranged in parallel and at intervals, and each transverse positioning blade 230a has a transverse positioning blade edge 231a. The plurality of longitudinal positioning blades 230b are arranged in parallel and at intervals, and each longitudinal positioning blade 230b has a longitudinal positioning blade edge 231b. Each transverse positioning blade 230a is arranged crosswise with each longitudinal positioning blade 230b, so that the plurality of transverse positioning blades 230a and the plurality of longitudinal positioning blades 230b together form a crisscross positioning blade group 230, and the plurality of transverse positioning blade edges 231a and the plurality of longitudinal positioning blade edges 231b together form a crisscross positioning blade group 231.

[0078] It is understandable that when the receiving plate 220 receives the silicone sheet, part of the adhesive of the silicone sheet will stick to the receiving plate 220, resulting in reduced viscosity of the silicone sheet leaving the receiving plate 220, so that the silicone sheet still has the risk of displacement after being bonded to the battery cell.

[0079] In order to avoid the decrease of the viscosity of the silicone sheet, in some preferred embodiments, the silicone stripping device 10a further includes a glue brushing mechanism, which is arranged adjacent to the material receiving mechanism 200, and is used to brush glue on the material receiving plate 220, so that glue is attached to both the material receiving plate 220 and the positioning blade assembly 230. In this embodiment, when the material receiving plate 220 receives the silicone, the silicone will contact the glue on the material receiving plate 220 and the positioning blade assembly 230, and when the silicone sheet leaves the material receiving plate 220, the silicone sheet will take away part of the glue on the material receiving plate 220 and the positioning blade assembly 230, which not only avoids the decrease of the viscosity of the silicone sheet, but also improves the viscosity of the silicone sheet, avoiding the risk of the silicone sheet being displaced after being bonded to the battery cell.

[0080] It should be noted that, since the glue brushing mechanism brushes less glue on the receiving plate 220 and the positioning blade assembly 230 , the adhesive layer will not block the adsorption holes 222 and the negative pressure holes 221 .

[0081] It can be understood that after the adhesive layer stays on the positioning blade group 230 for a long time, the adhesive layer will solidify on the positioning blade group 230, causing the transverse positioning blade 231a and the longitudinal positioning blade 231b to become blunt, resulting in the transverse positioning blade 231a and the longitudinal positioning blade 231b being unable to cut into the silicone, causing the position stability of the silicone to decrease and causing the roughness of the lower surface of the silicone sheet to be unable to be improved.

[0082] In order to avoid the problem of the lateral positioning blade 231a and the longitudinal positioning blade 231b becoming blunt, in some preferred embodiments, the material receiving assembly 200a further includes a heating element, which is connected to the material receiving plate 220. In this embodiment, the heating element generates heat after being powered on, and the heat generated by the heating element is transferred to the material receiving plate 220 and the positioning blade assembly 230, so that the glue on the material receiving plate 220 and the positioning blade assembly 230 remains in a liquid state, avoiding the problem of the lateral positioning blade 231a and the longitudinal positioning blade 231b becoming blunt, ensuring that the position stability of the silicone is high, and at the same time ensuring that the roughness of the lower surface of the silicone sheet is high, thereby making the position stability of the silicone sheet on the battery cell high.

[0083] However, since the glue is heated, the fluidity of the glue is greater, causing the glue to overflow from the receiving plate 220, resulting in a decrease in the amount of glue on the receiving plate 220 and the positioning blade assembly 230, thereby causing a decrease in the adhesion of the silicone sheet.

[0084] In order to prevent glue from overflowing, in some preferred embodiments, a first capillary glue locking groove and a second capillary glue locking groove are formed on the surface of each transverse positioning blade 230a, and a plurality of first capillary glue locking grooves are arranged at intervals, and a plurality of second capillary glue locking grooves are arranged at intervals, and each first capillary glue locking groove is mutually crossed and connected with each second capillary glue locking groove, so that a plurality of first capillary glue locking grooves and a plurality of second capillary glue locking grooves together form a criss-cross mesh capillary glue locking groove. In this embodiment, when the glue flows to the mesh capillary glue locking groove, due to the capillary action, that is, the capillary phenomenon, the inner wall of the mesh capillary glue locking groove will absorb the glue, that is, the mesh capillary glue locking groove will lock the glue, thereby inhibiting the flow of the glue and thus inhibiting the problem of glue overflow.

[0085] Furthermore, a first capillary adsorption groove and a second capillary adsorption groove are formed on the surface of each longitudinal positioning blade 230b, and a plurality of first capillary adsorption grooves are arranged at intervals, and a plurality of second capillary adsorption grooves are arranged at intervals, and each first capillary adsorption groove is intersected and connected with each second capillary adsorption groove, so that the plurality of first capillary adsorption grooves and the plurality of second capillary adsorption grooves together form a criss-crossed mesh capillary adsorption groove. In this embodiment, when the glue flows to the mesh capillary adsorption groove, due to the capillary action, that is, the capillary phenomenon, the inner wall of the mesh capillary adsorption groove will adsorb the glue, that is, the mesh capillary adsorption groove will lock the glue, thereby inhibiting the flow of the glue and further inhibiting the problem of glue overflow.
