Background technique

In the battery assembly production line, especially soft-pack batteries, in order to prevent the surface of the battery cells from being worn or scratched during the flow on the logistics line, it is necessary to cover the upper and lower surfaces of the battery cells with protective films (such as Mylar film). Before the cells are transferred to the thickness measurement station, the protective film on the cells needs to be removed to avoid measurement deviations.

In the related art, a film tearing mechanism can tear off the protective films on the upper and lower surfaces of the battery core.

Referring to FIGS. 1 and 2 , an embodiment of the present disclosure provides a film tearing device, which includes a film tearing assembly 10 and a waste collection assembly 20 . The film tearing assembly 10 is used to tear off the protective film B on the upper surface and/or the lower surface of the battery core A, and the waste collection assembly 20 is used to collect the protective film B torn off by the film tearing assembly 10 .

The film tearing assembly 10 includes a film tearing mechanism 11 and a clamping mechanism 12 . The clamping mechanism 12 is used to clamp the battery core A, and drive the battery core A to move along the first horizontal direction X1 and pass through the film tearing mechanism 11, so that the film tearing mechanism 11 can tear off the upper or lower surface of the battery core A. Protective film B. The waste collection assembly 20 includes a waste collection mechanism 22, a waste collection box 21 and a pushing mechanism (not labeled in the figure). The waste collection mechanism 22 is used to clamp the protective film B torn off by the film tearing mechanism 11 at the film tearing mechanism 11 and move it to the waste collection box 21 to stack the protective film B in the waste collection box 21 . The two sides of the waste collection box 21 in the second horizontal direction X2 are the blocking side a1 and the discharging side a2 respectively. The pushing mechanism is provided in the waste collection box 21 and is used to push the protective film B stacked in the waste collection box 21 from the blocking side a1 to the discharging side a2 along the second horizontal direction X2.

During the actual film tearing operation of the above-mentioned film tearing device, first, the clamping mechanism 12 clamps the battery core A to be filmed, and drives the battery core A to move along the first horizontal direction X1 and pass through the film tearing mechanism 11 . When the battery core A passes through the film tearing mechanism 11, the film tearing mechanism 11 picks up the protective film B on the upper or lower surface of the battery core A, so that the battery core A continues along the first During the movement in the horizontal direction X1, the film tearing mechanism 11 gradually tears off the picked-up protective film B. Then, the waste collection mechanism 22 moves to the film tearing mechanism 11 and clamps the protective film B torn off by the film tearing mechanism 11 , then moves to the top of the waste collection box 21 , and stacks the protective film B in the waste collection box 21 Inside. Complete the film tearing operation of several battery cells A one by one according to the above steps, and stack the torn off protective films B one by one and place them in the waste collection box 21 . When the protective film B in the waste collection box 21 is full, the pushing mechanism is controlled to push the stacked protective film B to move toward the discharge side a2 of the waste collection box 21 until the stacked protective film B is pushed out from the discharge side a2. This allows the waste collection box 21 to continue to accommodate the protective film B torn off from the battery core A.

In this way, after the protective film B is torn off by the film tearing mechanism 11, the torn off protective film B is clamped by the waste collection mechanism 22, and moved to the waste collection box 21, and then the protective film B is stacked and placed in the waste collection box. Inside box 21. On the one hand, the waste collection mechanism 22 transfers the torn-off protective film B to the waste collection box 21 for stacking in a translational manner, without changing the spatial angle of the torn-off protective film B, and can be directly stacked and placed, thereby greatly improving the efficiency of the stacking process. This reduces the risk of the adhesive surface of the protective film B coming into contact with other mechanisms and adhering to each other; on the other hand, the torn-off protective film B is stacked and stored using the waste collection box 21 and protected in the waste collection box 21 When the film B is full, the pushing mechanism is used to push all the stacked protective films B out of the waste collection box 21 from the discharging side a2, thereby simplifying the collection and cleaning of the protective films B, with a high degree of automation, and realizing the removal of waste materials without stopping the machine. , which is conducive to improving production efficiency.

Specifically in the embodiment, the number of film tearing mechanisms 11 is two, and the two film tearing mechanisms 11 are arranged oppositely in the vertical direction. The vertical direction may be the up and down direction in Figure 1 . The clamping mechanism 12 is used to drive the clamped battery core A to pass between the two film tearing mechanisms 11 along the first horizontal direction X1, so that the two film tearing mechanisms 11 can tear the upper surface and the lower surface of the battery core A respectively. membrane. That is to say, when the battery core A passes between the two film tearing mechanisms 11, the upper film tearing mechanism 11 tears off the protective film B on the upper surface of the battery core A, and the lower film tearing mechanism 11 tears off the battery core A. Protective film B on the lower surface.

Specifically in the embodiment, the film tearing mechanism 11 has a film tearing drive structure (not labeled) and a rubber roller 111 . The rubber roller 111 is installed at the driving end of the film tearing drive structure. The film tearing drive structure is used to drive the rubber roller 111 to move toward the battery core A to adhere the protective film B on the upper or lower surface of the battery core A. It should be noted that the film tearing driving structure can adopt relatively mature existing technology, as long as it can drive the rubber roller 111 to stick the protective film B on the battery core A, and there is no limitation here.

The supporting roller 131 is provided on the third mounting frame and is located below the clamping mechanism 12 to support the battery core A clamped by the clamping mechanism 12 and prevent the battery core A from rotating up and down. Optionally, the supporting driving structure 132 may use an electric cylinder, a pneumatic cylinder, a linear module, etc., as long as it can drive the third mounting bracket to move along the first horizontal direction X1, and is not limited here.

Specifically in the embodiment, the film tearing device also includes a battery core placement component 30 , which is used to place the battery core A to be peeled off for clamping by the clamping mechanism 12 . The battery core placement component 30 and the clamping mechanism 12 are spaced apart along the first horizontal direction X1. The two film tearing mechanisms 11 are located between the battery core placement component 30 and the clamping mechanism 12, so that the clamping mechanism 12 The driving structure 122 can drive the clamping structure 121 to pass between the two film tearing mechanisms 11 along the first horizontal direction X1 and reach the battery core placement assembly 30 to clamp the battery core A.

In this way, when the film needs to be peeled off, first, the battery core A to be peeled off is placed on the battery core placing assembly 30, and the clamping driving structure 122 drives the clamping structure 121 along the first horizontal direction X1 by one of the two film tearing mechanisms 11. (ie, moving from left to right as shown in FIG. 1 ), and reaches the battery core placing assembly 30 to clamp the battery core A on the battery core placing assembly 30 . Then, the clamping driving structure 122 drives the clamping structure 121 to return along the first horizontal direction X1 (that is, moving from right to left as shown in FIG. 1 ), thereby driving the clamped battery core A to be removed by the two film tearing mechanisms 11 passed between. Moreover, when the battery core A passes between the two film tearing mechanisms 11, the rubber rollers 111 of the two film tearing mechanisms 11 respectively stick to the protective films B on the upper and lower surfaces of the battery core A to achieve tearing. Protective film B on the upper and lower surfaces of lower battery cell A.

Further, the cell placement assembly 30 includes a cell placement frame 311 and a pressure roller 312 . The cell placement rack 311 is used to support the cell A whose film is to be torn off. The pressure roller 312 is rotatably connected to the battery core placement frame 311 and is located above the battery core A. When the clamping mechanism 12 drives the battery core A to move along the first horizontal direction X1, the pressure roller 312 can contact the upper surface of the battery core A to prevent the battery core A from angular deflection during the movement.

The longitudinal direction of the battery core A can be The length direction of battery cell A. That is to say, the battery core A is offset from the first preset angle c1 relative to the first horizontal direction Gradually tear off the protective film B, which will help reduce the difficulty of tearing off the film. degree to ensure that the protective film B can be peeled off accurately and reliably. Furthermore, since the longitudinal direction of the battery cell A and the first horizontal direction X1 are at the first preset angle c1, the protective film B torn off by the film tearing mechanism 11 is also at the first preset angle c1 with the first horizontal direction X1. The preset angle c1. The state of the same protective film B when it is applied on the surface of the battery core A and the state when it is torn off by the film tearing mechanism 11 are axially symmetrical to each other.

The second horizontal direction X2 and the first horizontal direction X1 form a second preset included angle c2. The second preset included angle c2 is complementary to the first preset included angle c1. That is to say, the second preset included angle c2 is complementary to the first preset included angle c1. The angle c2 plus the first preset angle c1 equals 90°, so that the second horizontal direction X2 is perpendicular to the long side of the protective film B stacked in the waste collection box 21, so that when pushing materials, the pushing mechanism is One long side of the stacked protective films B is in contact with each other, which facilitates the smooth push of the protective films B stacked in the waste collection box 21 out of the waste collection box 21 .

The channel 2110 on the bottom plate 211 extends along the second horizontal direction X2, so that the sliding seat 2322 can drive the 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 along the channel by the sliding seat 2322. 2110 mobile. The pushing driving member 2323 is disposed on the base 2321 and is drivingly connected with the sliding seat 2322 to drive the sliding seat 2322 to move relative to the base 2321 along the second horizontal direction X2, so that the sliding seat 2322 can drive the pushing plate through the connecting block 2324. 231 moves along the second horizontal direction X2 relative to the bottom plate 211, thereby achieving material pushing. Alternatively, the pusher driving member 2323 may be a cylinder.

Further, the base 2321 is provided with a first slide rail b1 extending longitudinally along the second horizontal direction The movement of the slider b2 along the first slide rail b1 guides the movement of the slider 2322 relative to the base 2321 along the second horizontal direction X2.

Specifically in this embodiment, the waste collection box 21 further includes a movable baffle 214 . The movable baffle 214 is provided on the discharge side a2. The movable baffle 214 can move relative to the bottom plate 211 to a blocking state or an avoidance state. When the movable baffle 214 is in the material blocking state, the movable baffle 214 blocks the protective film B stacked in the accommodating cavity a from being output from the discharge side a2. When the movable baffle 214 is in the avoidance state, the movable baffle 214 allows the protective film B stacked in the accommodation cavity a to be output from the discharge side a2.

In this way, when there is no need to push materials, the movable baffle 214 moves to the material blocking state to block the protective film B stacked in the accommodation cavity a from overflowing from the discharge side a2 of the waste collection box 21 . When the protective film B in the accommodation cavity a is full and needs to be pushed, the movable baffle 214 moves to the avoidance position, and then the pushing driving part 2323 drives the slide 2322 to move along the second horizontal direction X2, so that the slide 2322 passes The connecting block 2324 drives the pushing plate 231 to push the protective film B stacked in the accommodating cavity a from the discharge side a2.

Optionally, the movable baffle 214 can be switched between the blocking state and the avoidance state in a manner including but not limited to rotation and/or movement, which is not limited here.

Further, a handle 216 is installed on the movable baffle 214, and the operator can pull the movable baffle 214 by holding the handle 216, so that the movable baffle 214 switches between the blocking state and the avoidance state.

In other embodiments, the movable baffle 214 can be driven by a driving member including but not limited to a motor or a cylinder to automatically switch between the blocking state and the avoidance state.

Furthermore, a detection part 215 is also installed on the waste collection box 21, and the detection part 215 is used to detect whether the protective film B in the accommodation cavity a is full. Optionally, the detection component 215 may be a photoelectric sensor.

Please refer to FIG. 1 and FIG. 2 . In the embodiment of the present disclosure, the waste collection mechanism 22 includes a transfer structure 221 and a stacking structure 222 . The transfer structure 221 moves between the film tearing mechanism 11 and the top of the waste collection box 21 to transfer the protective film B torn off by the film tearing mechanism 11 to the top of the waste collection box 21 . The stacking structure 222 is arranged at the waste collection box 21 in a liftable manner to clamp the protective film B transferred by the transfer structure 221 and stack it into the waste collection box 21 .

In this way, when the film tearing mechanism 11 tears off the protective film B on the battery core A, first, the transfer structure 221 moves to the film tearing mechanism 11 and clamps the torn off protective film B. Then, the transfer structure 221 moves to above the waste collection box 21 . Then, the stacking structure 222 clamps the protective film B on the transfer structure 221, and the transfer structure 221 releases the protective film B and moves toward the film tearing mechanism 11 again to transfer the next protective film B. Then, the stacking structure 222 moves downward until the protective film B is stacked into the accommodation cavity a, and then the clamping of the protective film B is released.

Referring to FIG. 2 , FIG. 6 and FIG. 7 , in some embodiments, the transfer structure 221 includes a first mounting bracket 2211 and at least two first clamping units 2213 . The at least two first clamping units 2213 are both disposed on the first mounting bracket 2211 . The at least two first clamping units 2213 are spaced apart along the third horizontal direction X3, and each first clamping unit 2213 is used to clamp or release the protective film B along the vertical direction. The waste collecting mechanism 22 also includes a transfer driving structure 223 . The transfer driving structure 223 is drivingly connected to the first mounting bracket 2211 and is used to drive the first mounting bracket 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 structure 223 drives the first mounting frame 2211 to move along the first horizontal direction X1 to the film tearing mechanism 11 . Since each first clamping unit 2213 is arranged at intervals along the third horizontal direction Peel off the protective film B. After each first clamping unit 2213 clamps the torn off protective film B, the transfer driving structure 223 drives the first mounting bracket 2211 to move a certain distance along the second horizontal direction X2 to prevent the first mounting bracket 2211 from moving along the first horizontal direction X2. The horizontal direction X1 interferes with the clamping mechanism 12 when moving toward the waste collection box 21 . Then, the transfer driving structure 223 drives the first mounting bracket 2211 to move above the waste collection box 21 along the first horizontal direction X1. Then, the stacking structure 222 clamps the protective film B clamped by each first clamping unit 2213, each first clamping unit 2213 releases the protective film B, and the transfer driving structure 223 drives the first mounting frame 2211 along the first A horizontal direction X1 moves toward the film tearing mechanism 11 . The stacking structure 222 moves downward, thereby stacking the protective film B into the accommodation cavity a of the waste collection box 21 . Optionally, the first clamping unit 2213 may use air Moving jaw.

Further, the transfer driving structure 223 is also used to drive the first mounting frame 2211 to move in the vertical direction, so that the first mounting frame 2211 can move in the vertical direction between the two tearing film mechanisms 11, thereby allowing the two tearing film mechanisms 11 to move. The protective film B torn off by the film mechanism 11 can be clamped by each first clamping unit 2213 on the first mounting frame 2211 .

Specifically in the embodiment, the distance between each two adjacent first clamping units 2213 is adjustable, thereby conveniently adapting to protective films B of different specifications and improving the compatibility of the film tearing device. It should be noted that the installation method between each first clamping unit 2213 and the first mounting bracket 2211 can adopt relatively mature existing technology, as long as the distance between two adjacent first clamping units 2213 can be achieved. Just adjust it, there is no limit here.

Specifically in the embodiment, the transfer driving structure 223 includes a first driving member 2231, a first transfer base 2232, a second driving member 2233, a second transfer base 2234 and a third driving member 2235.

The first transfer base 2232 is connected to the driving end of the first driving member 2231, so that the first driving member 2231 can drive the first transfer base 2232 to move along the first horizontal direction X1. The second driving member 2233 is disposed on the first transfer base 2232, and the second transfer base 2234 is connected to the driving end of the second driving member 2233, so that the second driving member 2233 can drive the second transfer base 2234 along the second Move horizontally X2. The first mounting bracket 2211 is connected to the driving end of the third driving member 2235, so that the third driving member 2235 can drive the first mounting bracket 2211 to move in the vertical direction.

In this way, the first mounting bracket 2211 can be driven to move along the first horizontal direction X1 by the first driving part 2231, the first mounting bracket 2211 can be driven to move along the second horizontal direction X2 by the second driving part 2233, and the first mounting bracket 2211 can be driven by the third driving part 2235. The first mounting frame 2211 moves in the vertical direction to complete the transfer of the protective film B torn off by the film tearing mechanism 11 .

Optionally, the first driving member 2231, the second driving member 2233 and the third driving member 2235 can all adopt linear modules.

Referring to FIG. 9 and FIG. 10 , in some embodiments, the stacking structure 222 includes a second mounting bracket 2221 and at least two second clamping units 2223 . The at least two second clamping units 2223 are both disposed on the second mounting bracket 2221 . The at least two second clamping units 2223 are spaced apart along the third horizontal direction X3, and each second clamping unit 2223 is used to clamp or release the protective film B along the vertical direction. The waste collecting mechanism 22 also includes a stacking driving structure 224 drivingly connected to the second mounting bracket 2221. The stacking driving structure 224 is used to drive the second mounting bracket 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 top of the waste collection box 21 , first, the stacking driving structure 224 drives the second mounting bracket 2221 to move in the vertical direction to the transfer structure 221 . Since each second clamping unit 2223 is 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, Because they are arranged at intervals, the protective film B can be clamped stably and reliably by each second clamping unit 2223 . Then, the stacking driving structure 224 drives the second mounting frame 2221 to move toward the transfer structure 221 along the second horizontal direction X2 until each second clamping unit 2223 clamps the protective film B. Then, the transfer structure 221 loosens the protective film B and moves toward the film tearing mechanism 11 , and the stacking driving structure 224 drives the second mounting frame 2221 to move downward until the protective film B is stacked in the waste collection box 21 . Then, each second clamping unit 2223 releases the protective film B, and the stacking driving structure 224 drives the second mounting bracket 2221 to move along the second horizontal direction X2 to drive each second clamping unit 2223 to exit the waste collection box 21. Each second clamping unit 2223 is separated from the protective film B. At this time, the stacking of one protective film B is completed.

Specifically in this embodiment, the stacking driving structure 224 includes a fourth driving member 2241, a third transfer base 2242, and a fifth driving member 2243. The third transfer base 2242 is connected to the driving end of the fourth driving member 2241, so that the fourth driving member 2241 can drive the third transfer base 2242 to move in the vertical direction (ie, rise or fall). The fifth driving member 2243 is disposed on the third transfer base 2242, and the second mounting bracket 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 bracket 2221 along the second horizontal direction. X2 moves.

In this way, the fourth driving member 2241 can be used to drive the second mounting frame 2221 to move in the vertical direction, and the fifth driving member 2243 can be used to drive the second mounting frame 2221 to move in the second horizontal direction X2 to complete the stacking of the protective film B. Optionally, both the fourth driving member 2241 and the fifth driving member 2243 can adopt linear modules.

Specifically in the embodiment, the blocking side a1 of the waste collection box 21 has at least two escape grooves 2120 corresponding to each second clamping unit 2223 (see Figure 4 or Figure 5). Each escape groove 2120 extends in the vertical direction. When the stacking driving structure 224 drives the second mounting bracket 2221 to move in the vertical direction, each second clamping unit 2223 moves along the corresponding avoidance groove 2120, thereby preventing the waste collection box 21 from moving along each second clamping unit 2223. Vertical movement causes interference. When the stacking driving structure 224 drives the second mounting bracket 2221 to move along the second horizontal direction X2, each second clamping unit 2223 is withdrawn from the corresponding escape groove 2120 or inserted into the waste collection box 21. Further, the escape groove 2120 is opened on the above-mentioned baffle plate 212 .

Specifically in the embodiment, the distance between each two adjacent second clamping units 2223 is adjustable, thereby conveniently adapting to protective films B of different specifications and improving the compatibility of the film tearing device. It should be noted that the installation method between each second clamping unit 2223 and the second mounting bracket 2221 can adopt relatively mature existing technology, as long as the distance between two adjacent second clamping units 2223 can be achieved. Just adjust it, there is no limit here.

It can be understood that since the spacing between the second clamping units 2223 and the spacing between the escape grooves 2120 need to match each other, after adjusting the spacing between the second clamping units 2223, it is necessary to replace the corresponding baffle plate 212.

Specifically in the embodiment, each second clamping unit 2223 includes a clamping driving member 2224 and two clamping rollers 2225 respectively connected to the two driving ends of the clamping driving member 2224. The clamping driving member 2224 is used to drive the two clamping driving members 2224. The two clamping rods 2225 are close to each other in the vertical direction 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 bracket 2221, the clamping roller 2225 moves up and down along the corresponding escape groove 2120. When the second clamping unit 2223 moves along the second horizontal direction X2 following the second mounting bracket 2221, the clamping roller 2225 is inserted into or exits the accommodation cavity a through the corresponding escape groove 2120.

Furthermore, the cross section of the nip roller 2225 is circular or elliptical, so that the contact area with the protective film B is smaller when clamping the protective film B, thereby preventing the protective film B from sticking to the nip roller 2225 .

Furthermore, the outer surfaces of the two nip rollers 2225 are covered with particle tape, and the particle tape directly contacts the protective film B, further reducing the contact area and preventing the protective film B from sticking to the nip roller 2225.

It should be noted that when the protective film B clamped by the two clamping rollers 2225 is stacked in the waste collection box 21, if the clamping driving member 2224 is used to drive the two clamping rollers 2225 to open and release the protective film B, due to the opening force Larger, the nip roller 2225 is easily adhered closely to the lower protective film B.

In order to prevent the clamp roller 2225 from being tightly adhered to the lower protective film B, in one embodiment, an elastic member 2226 is installed on one of the driving ends of the clamping driving member 2224. When the clamping driving member 2224 drives the two clamping rollers 2225 to clamp the protective film B through its two driving ends, the two driving ends of the clamping driving member 2224 compress the elastic member 2226, so that the two driving ends are under the action of the elastic member 2226. The bottoms have a tendency to open to each other.

In this way, when it is necessary to loosen the protective film B, there is no need for the clamping driving member 2224 to provide the driving force to drive the two clamping rollers 2225 to open each other. It only needs to be in a leakage state, so that the clamping driving member 2224 The two driving ends open to each other under the elastic force of the elastic member 2226, thereby driving the two nip rollers 2225 to open to each other, thereby loosening the protective film B. That is to say, when the clamping driving member 2224 is in a release state, the elastic force provided by the elastic member 2226 is used to drive the two clamping rollers 2225 to open, so that the opening range of the two clamping rollers 2225 is small and the opening force is also small. This prevents the nip roller 2225 from being pressed against the lower protective film B and tightly adhered to each other. Optionally, the elastic member may be a spring plunger.

Alternatively, clamp drive 2224 may be a jaw cylinder. When the clamping jaw cylinder is in a leaking state, it means that the clamping jaw cylinder is in a state of exhausting after passing through the exhaust valve.

The technical features of the above embodiments can be combined in any way. To simplify the description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, All should be considered to be within the scope of this manual.
