On one hand, the waste collecting mechanism 22 transfers the torn protective film B to the waste collecting box 21 for stacking in a translation manner, the spatial angle of the torn protective film B does not need to be changed, and the protective film B can be directly stacked, so that the risk that the adhesive surfaces of the protective film B are mutually bonded by contacting with other mechanisms is greatly reduced; on the other hand, utilize scrap collecting box 21 to pile up the protection film B who is torn down and accomodate to when protection film B in scrap collecting box 21 piles up, utilize pushing equipment to push out scrap collecting box 21 with whole follow ejection of compact side a2 of protection film B that piles up, thereby simplified the collection and the clearance of protection film B, degree of automation is high, and has realized not shutting down the waste material, is favorable to improving production efficiency.

In the embodiment, the number of the film tearing mechanisms 11 is two, and the two film tearing mechanisms 11 are oppositely arranged in the vertical direction. The clamping mechanism 12 is used for driving the clamped battery cell a to pass through between the two film tearing mechanisms 11 along the first horizontal direction X1, so that the two film tearing mechanisms 11 respectively tear the upper surface and the lower surface of the battery cell a. That is to say, in the process that the battery cell a passes between the two film tearing mechanisms 11, the upper film tearing mechanism 11 tears the protective film B on the upper surface of the battery cell a, and the lower film tearing mechanism 11 tears the protective film B on the lower surface of the battery cell a.

Specifically, in the embodiment, the film tearing mechanism 11 has a film tearing driving structure (not shown) and a glue-pulling roller 111 installed at a driving end of the film tearing driving structure, and the film tearing driving structure is configured to drive the glue-pulling roller 111 to move toward the electric core a, so as to adhere the protective film B on the upper surface or the lower surface of the electric core a. It should be noted that, the tear-off driving structure may adopt a mature prior art, as long as it can drive the glue drawing roller 111 to stick the protective film B on the battery cell a, which is not limited herein.

Specifically, in the embodiment, the clamping mechanism 12 includes a clamping driving structure 122 and a clamping structure 121 disposed at a driving end of the clamping driving structure 122, where the clamping structure 121 is configured to clamp the battery cell a, and the clamping driving structure 122 is configured to drive the clamping structure 121 to move along the first horizontal direction X1. Alternatively, the clamping driving structure 122 may adopt an electric cylinder, an air cylinder, a linear module, or the like, as long as it can drive the clamping structure 121 to move along the first horizontal direction X1, and is not limited herein. The clamping structure 121 may be an electric claw or a gas claw, as long as it can clamp the battery cell a, and is not limited herein.

Specifically, in the embodiment, the film tearing assembly 10 further includes a cell supporting mechanism 13, and the cell supporting mechanism 13 includes a supporting driving structure 132, a third mounting frame (not shown), and a supporting roller 131. The third mounting bracket is connected to the driving end of the support driving structure 132, so as to be driven by the support driving structure 132 to move along the first horizontal direction X1. Bearing roller 131 sets up on the third mounting bracket, and is located fixture 12's below for carry out the bearing to the electric core A of fixture 12 centre gripping, prevent that this electric core A from taking place the tilting. Alternatively, the supporting driving structure 132 may be an electric cylinder, an air cylinder, a linear module, or the like, as long as it can drive the third mounting frame to move along the first horizontal direction X1, and the supporting driving structure is not limited herein.

Specifically, in the embodiment, the film tearing device further includes a battery cell placing assembly 30, where the battery cell placing assembly 30 is used for placing a battery cell a to be torn, so as to be clamped by the clamping mechanism 12. This subassembly 30 is placed to electric core and fixture 12 is laid along first horizontal direction X1 interval, and two dyestripping mechanism 11 all are located between subassembly 30 and the fixture 12 are placed to the electric core to make the centre gripping drive structure 122 of fixture 12 can drive clamping structure 121 and pass between by two dyestripping mechanism 11 along first horizontal direction X1, and reach electric core and place subassembly 30 department clamp and get electric core A. Thus, when the film needs to be torn, firstly, the battery cell a to be torn is placed on the battery cell placement assembly 30, and the clamping driving structure 122 drives the clamping structure 121 to pass through between the two film tearing mechanisms 11 along the first horizontal direction X1 (i.e., move from left to right as shown in fig. 1), and reach the battery cell placement assembly 30, so as to clamp the battery cell a on the battery cell placement assembly 30. Then, the clamping driving structure 122 drives the clamping structure 121 to return along the first horizontal direction X1 (i.e. move from right to left as shown in fig. 1), so as to drive the clamped battery cell a to pass between the two film tearing mechanisms 11. In addition, in the process that the battery cell a passes through the two film tearing mechanisms 11, the glue pulling rollers 111 of the two film tearing mechanisms 11 respectively stick the protective films B on the upper surface and the lower surface of the battery cell a, so that the protective films B on the upper surface and the lower surface of the battery cell a are torn off.

Further, the cell placing assembly 30 includes a cell placing frame 311 and a pressing roller 312. The battery cell placing frame 311 is used for supporting a battery cell a to be subjected to film tearing. The compression roller 312 is rotatably connected to the cell placing frame 311, and is located above the cell a. The pressing roller 312 is configured to contact the upper surface of the battery cell a when the clamping mechanism 12 drives the battery cell a to move along the first horizontal direction X1, so as to prevent the battery cell a from generating angular deflection in the moving process.

Please refer to fig. 1 to fig. 3, in an embodiment of the present invention, the lengthwise direction of the battery cell a and the first horizontal direction X1 are a first predetermined included angle c1, that is, the battery cell a is offset from the first horizontal direction X1 in the horizontal plane by the first predetermined included angle c1, so that the film tearing mechanism 11 gradually tears the protection film B from one corner of the battery cell a to another corner that forms a diagonal angle with the corner, which is beneficial to reducing the difficulty of tearing the film, and ensures that the protection film B can be torn accurately and reliably. Further, since a first preset included angle c1 is formed between the longitudinal direction of the battery cell a and the first horizontal direction X1, the protection film B torn by the film tearing mechanism 11 also forms the first preset included angle c1 with the first horizontal direction X1, but the state of the same protection film B when being attached to the surface of the battery cell a and the state when being torn by the film tearing mechanism 11 are axisymmetric (see fig. 3).

The second horizontal direction X2 and the first horizontal direction X1 are a second preset included angle c2, the second preset included angle c2 is complementary to the first preset included angle c1, namely, the second preset included angle c2 and the first preset included angle c1 are equal to 90 degrees, the second horizontal direction X2 is perpendicular to the long edge of the protection film B stacked in the waste collection box 21, the pushing mechanism is abutted to the long edge of the protection film B stacked in the waste collection box 21 when pushing materials, and therefore the protection film B stacked in the waste collection box 21 can be smoothly pushed out of the waste collection box 21.

Referring to fig. 4 to 6, in an embodiment, the scrap collecting box 21 includes a bottom plate 211, and a striker plate 212 and two side plates 213 disposed around the bottom plate 211. The two side plates 213 are oppositely disposed on two sides of the bottom plate 211 in the third horizontal direction X3, and the material blocking plate 212 is disposed on the material blocking side a1, so that the material blocking plate 212 and the two side plates 213 together enclose a receiving cavity a for receiving the torn-off protective film B on the bottom plate 211. The third horizontal direction X3 is perpendicular to the second horizontal direction X2. So, set up two curb plates 213 in bottom plate 211 along third horizontal direction X3 both sides, and striker plate 212 sets up in one side of bottom plate 211 on second horizontal direction X2 to make the space deflection angle of garbage collection box 21 and the space deflection angle phase-match of the protection film B who is torn down, and then make the protection film B who is torn down can neatly pile up and place in holding chamber a, can hold more protection films B. Optionally, the inner sides of the bottom plate 211 and the side plate 213 may be covered with particle adhesive tape to prevent adhesion with the protective film B.

In a specific embodiment, the scrap collecting box 21 further includes a plurality of support bars 217 disposed on the bottom plate 211 at intervals from each other, the plurality of support bars 217 serving to support the protective film B in common. Thus, the torn protective films B are stacked one by one on the support bars 217, so that the protective films B are prevented from directly contacting the bottom plate 211, the contact area is reduced, and the situation that the protective films B cannot be pushed out of the scrap collecting box 21 by a pushing mechanism due to the fact that the protective films B are bonded with the bottom plate 211 is avoided.

In one embodiment, the pushing mechanism includes a pushing plate 231 and a pushing driving mechanism 232. The material pushing plate 231 is disposed in the accommodating chamber a and is movable in the second horizontal direction X2 relative to the bottom plate 211, so as to push the protection films B stacked in the accommodating chamber a toward the discharging side a2. The pushing driving mechanism 232 is drivingly connected to the pushing plate 231 to drive the pushing plate 231 to move along the second horizontal direction X2 relative to the bottom plate 211. Under the driving of the material pushing driving mechanism 232, the material pushing plate 231 pushes the protection film B stacked in the accommodating cavity a from the material stopping side a1 to the material discharging side a2. Alternatively, the side of the ejector plate 231 in contact with the protective film B may be coated with a particle tape so as to avoid adhesion with the protective film B.

Optionally, the material pushing driving mechanism 232 includes a base 2321, a sliding seat 2322, a connecting block 2324 and a material pushing driving member 2323. The base 2321 is disposed below the bottom plate 211, and the sliding base 2322 is movably coupled to the base 2321 along the second horizontal direction X2. One end of the connecting block 2324 is fixedly connected to the base 2321, and the other end of the connecting block 2324 penetrates into the accommodating cavity a through the channel 2110 of the bottom plate 211 and is fixedly connected to the stripper plate 231. The channel 2110 on the bottom plate 211 extends lengthwise along the second horizontal direction X2, so that the sliding base 2322 can drive the material pushing plate 231 to move along the second horizontal direction X2 through the connecting block 2324, that is, the connecting block 2324 can be driven by the sliding base 2322 to move along the channel 2110. The pushing driving element 2323 is disposed on the base 2321 and is drivingly connected to the sliding seat 2322 to drive the sliding seat 2322 to move along the second horizontal direction X2 relative to the base 2321, so that the sliding seat 2322 can drive the pushing plate 231 to move along the second horizontal direction X2 relative to the bottom plate 211 through the connecting block 2324, thereby pushing the material. Alternatively, material pushing drive 2323 may be a pneumatic cylinder.

Further, a first sliding rail b1 longitudinally extending along the second horizontal direction X2 is disposed on the base 2321, and a first sliding block b2 slidably engaged with the first sliding rail b1 is disposed on the sliding seat 2322, so that the sliding seat 2322 is guided to move along the second horizontal direction X2 relative to the base 2321 by the movement of the first sliding block b2 along the first sliding rail b 1.

In the embodiment, the waste collection box 21 further includes a movable baffle 214 disposed on the discharging side a2, and the movable baffle 214 is movable to a blocking state or an avoiding state relative to the bottom plate 211. When the movable baffle 214 is in the blocking state, the movable baffle 214 blocks the protective film B stacked in the accommodating chamber a from being output from the discharging side a2. When the flapper 214 is in the retracted state, the flapper 214 allows the protective film B stacked in the accommodation chamber a to be discharged from the discharge side a2. Thus, when the material pushing is not needed, the movable baffle 214 moves to the blocking state to block the protective film B stacked in the accommodating cavity a from overflowing from the discharging side a2 of the waste collection box 21. When the protective film B in the accommodating cavity a is fully stacked and needs to be pushed, the movable baffle 214 moves to an avoidance position, and then the pushing driving member 2323 drives the sliding seat 2322 to move along the second horizontal direction X2, so that the sliding seat 2322 drives the pushing plate 231 to push the protective film B stacked in the accommodating cavity a out of the discharging side a2 through the connecting block 2324.

It should be noted that the movable baffle 214 may be switched between the blocking state and the avoiding state by rotating and/or moving, which is not limited herein.

Further, a handle 216 is installed on the movable baffle 214, and an operator can pull the movable baffle 214 by holding the handle 216, so that the movable baffle 214 is switched between the blocking state and the avoiding state. Of course, in other embodiments, the movable barrier 214 may also be driven by a driving member such as a motor or an air cylinder, and automatically switch between the blocking state and the avoiding state.

Further, a detecting member 215 is mounted on the scrap collecting box 21, and the detecting member 215 is used for detecting whether the protective film B in the accommodating chamber a is fully stacked. Alternatively, the detecting member 215 may be a photoelectric sensor.

Referring to fig. 1 and 2, in an embodiment of the present invention, the waste collecting mechanism 22 includes a transferring structure 221 and a stacking structure 222. The transfer mechanism 221 moves between the film tearing mechanism 11 and above the scrap collecting box 21 to transfer the protective film B torn by the film tearing mechanism 11 to above the scrap collecting box 21. The stacking structure 222 is arranged at the scrap collecting box 21 to be liftable to pick up the protective film B transferred by the transfer structure 221 and to be stacked into the scrap collecting box 21. In this way, when the film tearing mechanism 11 tears the protective film B from the battery cell a, first, the transferring mechanism 221 moves to the film tearing mechanism 11 and clamps the torn protective film B. The transfer structure 221 is then moved over the scrap collection box 21. Then, the stacking structure 222 grips the protective film B on the transfer structure 221, and the transfer structure 221 releases the protective film B and moves again toward the peeling mechanism 11 to transfer the next protective film B. Then, the stacking structure 222 moves downward until the protective film B is stacked in the accommodating chamber a, and then the holding of the protective film B is released.

Referring to fig. 2, 6 to 7, in some embodiments, the transfer structure 221 includes a first mounting frame 2211 and at least two first clamping units 2213 both disposed on the first mounting frame 2211. The at least two first clamping units 2213 are arranged at intervals in the third horizontal direction X3, and each first clamping unit 2213 is used for clamping or releasing the protective film B in the vertical direction. The waste collecting mechanism 22 further includes a transfer driving structure 223 drivingly connected to the first mounting block 2211, wherein the transfer driving structure 223 is configured to drive the first mounting block 2211 to move along the first horizontal direction X1 and the second horizontal direction X2. In this way, when the protective film B needs to be transferred, the transfer driving mechanism 223 drives the first mounting frame 2211 to move to the film tearing mechanism 11 along the first horizontal direction X1, and since the first clamping units 2213 are arranged at intervals along the third horizontal direction X3, that is, at intervals along the longitudinal direction of the torn protective film B, the torn protective film B can be stably and reliably clamped by the first clamping units 2213. After each of the first clamping units 2213 clamps the torn-off protective film B, the transfer driving mechanism 223 drives the first mounting block 2211 to move a certain distance along the second horizontal direction X2, so as to avoid interference with the clamping mechanism 12 when the first mounting block 2211 moves along the first horizontal direction X1 to the scrap collecting box 21. Then, the transfer driving structure 223 drives the first mounting frame 2211 to move to the upper side of the scrap collecting box 21 in the first horizontal direction X1. Then, the stacking structure 222 grips the protective film B gripped by each first grip unit 2213, each first grip unit 2213 releases the protective film B, and the transfer driving structure 223 drives the first mount 2211 to move toward the peeling mechanism 11 along the first horizontal direction X1. The stacking structure 222 moves downward to stack the protective film B into the housing chamber a of the scrap collecting box 21. Alternatively, the first clamping unit 2213 may employ a pneumatic clamping jaw.

Further, the transfer driving structure 223 is further configured to drive the first mounting frame 2211 to move in the vertical direction, so that the first mounting frame 2211 can move between the two film tearing mechanisms 11 in the vertical direction, and the protective films B torn by the two film tearing mechanisms 11 can be clamped by the respective first clamping units 2213 on the first mounting frame 2211.

In the embodiment, the distance between every two adjacent first clamping units 2213 is adjustable, so that the film tearing device is convenient to adapt to protective films B with different specifications, and the compatibility of the film tearing device is improved. It should be noted that, the installation manner between each first clamping unit 2213 and the first mounting frame 2211 may adopt a mature prior art, and only the distance between two adjacent first clamping units 2213 can be adjustable, which is not limited herein.

Specifically, in the embodiment, the transfer driving structure 223 includes a first driving member 2231, a first transfer seat 2232, a second driving member 2233, a second transfer seat 2234, and a third driving member 2235. The first transfer base 2232 is connected to a driving end of the first driving member 2231 so that the first driving member 2231 can drive the first transfer base 2232 to move in the first horizontal direction X1. The second driving unit 2233 is disposed on the first transfer seat 2232, and the second transfer seat 2234 is connected to a driving end of the second driving unit 2233 such that the second driving unit 2233 can drive the second transfer seat 2234 to move in the second horizontal direction X2. The first mounting bracket 2211 is connected to the driving end of the third driver 2235 so that the third driver 2235 can drive the first mounting bracket 2211 to move in the vertical direction. In this way, the first mounting frame 2211 can be driven by the first driving member 2231 to move along the first horizontal direction X1, the first mounting frame 2211 is driven by the second driving member 2233 to move along the second horizontal direction X2, and the first mounting frame 2211 is driven by the third driving member 2235 to move along the vertical direction, so as to complete the transfer of the protective film B torn off by the film tearing mechanism 11. Alternatively, the first driving member 2231, the second driving member 2233 and the third driving member 2235 may adopt a linear module.

Referring to fig. 9 and 10, in some embodiments, the stacking structure 222 includes a second mounting frame 2221 and at least two second clamping units 2223 disposed on the second mounting frame 2221. The at least two second clamping units 2223 are arranged at intervals in the third horizontal direction X3, and each second clamping unit 2223 is configured to clamp or release the protective film B in the vertical direction. The waste collection mechanism 22 further includes a stacking drive structure 224 drivingly connected to the second mounting bracket 2221. The stacking drive structure 224 is configured to drive the second mounting frame 2221 to move in the vertical direction and the second horizontal direction X2. In this way, after the transfer structure 221 transfers the protective film B to the upper side of the scrap collecting box 21, firstly, the stacking drive structure 224 drives the second mounting brackets 2221 to move to the transfer structure 221 along the vertical direction, since the respective second clamping units 2223 are arranged at intervals along the third horizontal direction X3, that is, along the longitudinal direction of the protective film B of the transfer structure 221, the protective film B can be stably and reliably clamped by the respective second clamping units 2223. Then, the stacking driving structure 224 drives the second mounting frame 2221 to move toward the transfer structure 221 in the second horizontal direction X2 until each second clamping unit 2223 clamps the protective film B. Then, the transfer mechanism 221 releases the protective film B and moves toward the film tearing mechanism 11, and the stacking drive mechanism 224 drives the second mounting bracket 2221 to move downward until the protective film B is stacked in the scrap collecting box 21. Then, the second clamping units 2223 release the protective films B, and the stacking driving mechanism 224 drives the second mounting frame 2221 to move along the second horizontal direction X2, so as to drive the second clamping units 2223 to exit the scrap collecting box 21, so that the second clamping units 2223 are separated from the protective films B, and at this time, the stacking of one protective film B is completed.

In the embodiment, the stacking driving structure 224 includes a fourth driving member 2241, a third transferring seat 2242 and a fifth driving member 2243. The third transfer seat 2242 is connected to a driving end of the fourth driving member 2241 so that the fourth driving member 2241 can drive the third transfer seat 2242 to move in the vertical direction (i.e., to ascend or descend). The fifth driving member 2243 is disposed on the third transfer seat 2242, and the second mounting rack 2221 is connected to the driving end of the fifth driving member 2243, so that the fifth driving member 2243 can drive the second mounting rack 2221 to move along the second horizontal direction X2. In this way, the second mounting rack 2221 can be driven by the fourth driving member 2241 to move in the vertical direction, and the second mounting rack 2221 can be driven by the fifth driving member 2243 to move in the second horizontal direction X2, so as to complete the stacking of the protection films B. Optionally, the fourth driving member 2241 and the fifth driving member 2243 can both adopt a linear module.

In a specific embodiment, the material blocking side a1 of the scrap collecting box 21 has at least two escape grooves 2120 (see fig. 4 or 5) corresponding to the respective second clamping units 2223 one to one, and each escape groove 2120 extends lengthwise in the vertical direction. When the stacking drive structure 224 drives the second mounting brackets 2221 to move in the vertical direction, each of the second clamping units 2223 moves along the corresponding escape groove 2120, thereby preventing the scrap collecting box 21 from interfering with the movement of each of the second clamping units 2223 in the vertical direction. When the stacking drive structure 224 drives the second mounting brackets 2221 to move in the second horizontal direction X2, each of the second clamping units 2223 is withdrawn from or inserted into the waste collection box 21 through the corresponding escape groove 2120. Further, the escape groove 2120 is formed in the striker plate 212.

In the embodiment, the distance between every two adjacent second clamping units 2223 is adjustable, so that the protective films B with different specifications can be conveniently adapted, and the compatibility of the film tearing device is improved. It should be noted that, the installation manner between each second clamping unit 2223 and the second mounting frame 2221 may adopt a mature prior art, and only the distance between two adjacent second clamping units 2223 can be adjusted, which is not limited herein. It can be understood that, since the spacing between the respective second clamping units 2223 and the spacing between the respective escape grooves 2120 need to be matched with each other, after the spacing between the respective second clamping units 2223 is adjusted, the corresponding striker plate 212 needs to be replaced.

In an embodiment, each of the second clamping units 2223 includes a clamping driving member 2224 and two clamping rollers 2225 respectively connected to two driving ends of the clamping driving member 2224, and the clamping driving member 2224 is used for driving the two clamping rollers 2225 to approach each other in a vertical direction so as to clamp the protective film B. It should be noted that, when the second clamping unit 2223 moves in the vertical direction following the second mounting frame 2221, the clamping rollers 2225 move up and down along the corresponding escape grooves 2120. When the second clamping unit 2223 moves in the second horizontal direction X2 following the second mounting frame 2221, the clamping rollers 2225 are inserted into or withdrawn from the accommodating chamber a by the corresponding escape grooves 2120.

Further, the cross section of the nip roller 2225 is circular or elliptical, so that the contact area with the protective film B when the protective film B is nipped is small, and the protective film B is prevented from sticking to the nip roller 2225.

Further, the outer surfaces of the two nip rollers 2225 are coated with the particle adhesive tapes, and the particle adhesive tapes are in direct contact with the protective film B, so that the contact area is further reduced, and the protective film B is prevented from being adhered to the nip rollers 2225.

It should be noted that, when the protective film B clamped by the two clamping rollers 2225 is stacked on the scrap collecting box 21, if the two clamping rollers 2225 are driven to open by the clamping driving member 2224 to release the protective film B, the clamping rollers 2225 are easily adhered to the lower protective film B due to the large opening force.

In order to avoid the phenomenon that the nip roller 2225 is tightly adhered to the lower protective film B, in one embodiment, an elastic member 2226 is mounted on one of the driving ends of the clamping driving member 2224, and when the clamping driving member 2224 drives the two nip rollers 2225 to nip the protective film B through the two driving ends thereof, the two driving ends of the clamping driving member 2224 compress the elastic member 2226, so that the elastic member 2226 provides a movement tendency that the two driving ends are spread apart from each other. In this way, when the protective film B needs to be released, the clamping driving member 2224 does not need to provide a driving force for driving the two clamping rollers 2225 to open, but only needs to be in a force-releasing state, so that the two driving ends of the clamping driving member 2224 open under the elastic force of the elastic member 2226, and thus the two clamping rollers 2225 are driven to open, and thus the protective film B needs to be released. That is, when the clamping driving member 2224 is in the force-releasing state, the two clamping rollers 2225 are driven to open by the elastic force provided by the elastic member 2226, so that the opening range of the two clamping rollers 2225 is small, and the opening force is also small, thereby preventing the clamping rollers 2225 from being tightly adhered to the lower protective film B by being pressed against the lower protective film B. Alternatively, the resilient member may employ a spring plunger.

Alternatively, the clamp drive 2224 may be a jaw cylinder. The clamping jaw cylinder is in a force release state, namely the clamping jaw cylinder is in a state after air leakage through the exhaust valve.
