Before attaching the spacer to the battery cell, the release film on the lower surface of the spacer needs to be torn off so that the spacer can be attached to the upper surface of the battery cell. After the spacer is attached, the release film on the upper surface of the spacer needs to be torn off so that the battery cell can be bonded to the adjacent battery cell when stacked.

[0004] The current spacer mounting method is as follows: the upper surface film tearing, the patch mounting and the lower surface film tearing processes are completed in different processing equipment, which not only increases the equipment cost, but also affects the spacer efficiency.

[0060] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0061] The present application provides a battery cell patch device, which is used to mount a spacer on a battery cell. The spacer to be mounted has release films on both the upper and lower surfaces, and one end of the release film is formed with a tearing end extending outward from the spacer.

[0062] like Figure 1 and Figure 2 As shown, the cell patch equipment in the embodiment of the present application includes a cell conveying mechanism 1, a spacer supply mechanism 2, a spacer handling mechanism 3, a spacer regularization mechanism 4, a back film tearing mechanism 5 and a front film tearing mechanism 6, wherein:

[0063] The battery cell conveying mechanism 1 is configured to convey the battery cells 200 , and a tidying station A, a patch station B and a front film tearing station C are sequentially arranged on the conveying path of the battery cell conveying mechanism 1 .

[0064] The separator conveying mechanism 3 is configured to pick up separators from the feeding station D of the separator supply mechanism 2 and convey the separators to the separator aligning mechanism 4 located at the aligning station A.

[0065] The separator aligning mechanism 4 is configured to align the separators, and the separator conveying mechanism 3 is further configured to pick up the aligned separators from the separator aligning mechanism 4 and convey the picked-up aligned separators to the back film tearing station E.

[0066] The back film tearing mechanism 5 is located beside the back film tearing station E. The back film tearing mechanism 5 is configured to cooperate with the separator conveying mechanism 3 to tear off the release film on the lower surface of the separator.

[0067] The spacer conveying mechanism 3 is further configured to convey the spacer with the release film on the lower surface removed and mount it on the battery cell 200 located at the mounting station B.

[0068] The front film tearing mechanism 6 is arranged outside the front film tearing station C, and the front film tearing mechanism 6 is used to tear off the release film on the upper surface of the separator attached to the battery cell.

[0069] Combined with reference Figure 1 and Figure 2 As shown, the optional working process of the battery cell patch device in the embodiment of the present application is as follows:

[0070] The cell conveying mechanism 1 is arranged along a first horizontal direction (eg Figure 1 and Figure 2 The battery cells are transported in a step-by-step manner (in the direction indicated by the middle arrow), so that the battery cells arrive at the arranging station A, the patch station B and the front film tearing station C in sequence.

[0071] The spacer conveying mechanism 3 mounts the spacer that has completed the back film tearing onto the battery cell 200 located at the patch station B. The specific process is as follows: the spacer conveying mechanism 3 first picks up a spacer from the feeding station D of the spacer supply mechanism 2, and then transports the spacer to the spacer regularization mechanism 4. After the spacer regularization mechanism 4 completes the position adjustment of the spacer, the spacer conveying mechanism 3 picks up the spacer from the spacer regularization mechanism 4 and transports the spacer to the back film tearing station E. Then, the spacer conveying mechanism 3 cooperates with the back film tearing mechanism 5 to tear off the release film on the lower surface of the spacer. Finally, the spacer conveying mechanism 3 transports the spacer that has completed the tearing of the release film on the lower surface and mounts it on the battery cell 200 located at the patch station B.

[0072] When the battery cell 200 with the spacer mounted thereon arrives at the front film tearing station C, the front film tearing mechanism 6 tears off the release film on the upper surface of the spacer. At this point, all the processes of spacer installation are completed.

[0073] The battery cell conveying mechanism 1 continues to convey the battery cells 200 with the spacers attached thereto to the downstream.

[0074] It can be seen that the battery cell mounting equipment of the embodiment of the present application can sequentially and continuously complete the spacer regularization, spacer lower surface release film tearing, spacer mounting and spacer upper surface release film tearing, which improves the spacer mounting efficiency and reduces the equipment cost.

[0075] like Figure 3 As shown, optionally, the spacer supply mechanism 2 includes a lifting mechanism 21, a turntable 22, a turntable driving mechanism 23 and several (such as Figure 3 Six) material racks 24, wherein: a plurality of material racks 24 are arranged on the turntable 22 along the circumferential direction, each material rack 24 is used to stack spacers, and a top-feeding hole no larger than the spacer is opened at the bottom of each material rack 24. The turntable 22 is connected to the driving end of the turntable driving mechanism 23, and the turntable driving mechanism 23 is used to drive the turntable 22 to rotate, so as to drive each material rack 24 to rotate to the feeding station D of the spacer supply mechanism in turn. The lifting mechanism 21 is arranged below the feeding station D, and the lifting mechanism 21 is used to lift the spacer in the material rack 24 located at the feeding station D upward through the top-feeding hole. The spacer conveying mechanism 3 is used to pick up the topmost spacer that has been lifted from the material rack 24 located at the feeding station D.

[0076] The plurality of racks 24 driven by the turntable 22 are rotated and switched to the feeding station D in sequence. After the spacers in the rack 24 currently located at the feeding station D are taken out by the spacer transport mechanism 3, the next rack 24 filled with spacers is rotated and switched to the feeding station D, thereby realizing continuous feeding of spacers. After the empty rack 24 leaves the feeding station D, refilling can be implemented.

[0077] like Figure 1 and Figure 2As shown, optionally, the spacer transport mechanism 3 includes a bracket 31, a rotating part 32 and at least one spacer picking part 33. The bracket 31 is mounted above the battery cell conveying mechanism 1, and the fixed part of the rotating part 32 is installed on the bracket 31. The rotating part 32 is used to drive the spacer picking part 33 to rotate step by step, so that the spacer picking part 33 sequentially steps to the feeding station D, the regularization station A, the back film tearing station E and the patch station B.

[0078] That is, the feeding station D, the arranging station A, the back film tearing station E and the patch station B are sequentially arranged on the rotation path of the spacer picking-up unit 33. Driven by the rotating unit 32, the spacer picking-up unit 33 picks up the spacer from the feeding station D, and then sequentially rotates the picked-up spacer to the arranging station A, the back film tearing station E and the patch station B, thereby sequentially and continuously completing the arranging of the spacer, the tearing of the release film on the lower surface of the spacer, the patching of the spacer and the tearing of the release film on the upper surface of the spacer.

[0079] like Figure 2 and Figures 10 to 12 As shown, optionally, the spacer transport mechanism 3 includes four spacer picking parts 33. The rotating part 32 includes a rotating driving member 321, a base 322 and a turntable 323, wherein: the base 322 is mounted on the bracket 31, the rotating driving member 321 is mounted on the base 322, the turntable 323 is rotatably mounted on the base 322 through a plane bearing, the rotating end of the rotating driving member 321 is connected to the turntable 323, the rotating driving member 321 is configured to drive the turntable 323 to rotate horizontally along its own axis, and the four spacer picking parts 33 are equidistantly mounted on the turntable 323 along the circumference of the turntable 323. After each step rotation of the rotating part 32, there is a spacer picking part 33 at the feeding station D, the regularization station A, the back film tearing station E and the patch station B.

[0080] Optionally, the spacer picking portion 33 includes a support seat 331, a suction cup 332 and a lifting drive member 333. The support seat 331 is mounted on the turntable 323, and the support seat 331 can slide vertically relative to the turntable 323. The suction cup 332 is mounted at the bottom of the support seat 331, and the suction cup 332 is used to pick up the spacer. Four arc-shaped slide rails extend downward from the periphery of the base 322, and a gap is formed between two adjacent slide rails in front of the lifting drive member 333 of a spacer picking portion 33. The fixed end of the lifting drive member 333 is mounted on the base 322, and a support plate is arranged at the gap between two adjacent slide rails on the lifting end of the lifting drive member 333. A rotatable roller is arranged at the top of the support seat 331, and the roller can roll against the upper surface of the support plate and the slide rail, and the four support plates and the four slide rails together form a circular track for the roller to roll. When the rotary drive member 321 drives the turntable 323 to rotate horizontally along its own axis, the rollers of the four spacer picking parts 33 will roll along the circular track.

[0081] When the separator picking part 33 moves to one of the feeding station D, the regularization station A, the back film tearing station E and the patch station B, the roller of the separator picking part 33 will be exactly located on the support plate of one of the lifting driving members 333. At this time, the moving end of the lifting driving member 333 will drive the support plate to descend, and the roller carried on the support plate will follow the support plate to descend, thereby driving the suction cup 332 at the bottom of the support seat 331 to descend, so as to place the separator at the lower station.

[0082] The spacer picking part 33 also includes a limit spring located between the turntable 323 and the suction cup 332. The first end of the limit spring is fixed on the support seat 331, and the second end is fixed on the turntable 323. When the lifting drive 333 drives the support plate to descend, the roller at the top of the support seat 331 is pressed against the support plate with the help of the limit spring. Through the above design, the suction cup 332 and the moving end of the lifting drive 333 are maintained to move synchronously, ensuring the moving accuracy of the spacer picking part 33 when lifting; when the suction cup 332 is needed to press the spacer against the battery cell at the patch station B, the suction cup 332 can also provide sufficient downward pressure.

[0083] With the cooperation of the rotary drive member 321, the turntable 323 and the separator picking unit 33, it can be achieved that at the same time, the separator picking unit 33 at the feeding station D picks up the first separator from the feeding station D, the separator picking unit 33 at the regularization station A places the second separator on the separator regularization mechanism 4 for regularization, the separator picking unit 33 at the back film tearing station E cooperates with the back film tearing mechanism 5 to tear off the release film on the lower surface of the third separator, and the separator picking unit 33 at the patch station B mounts the fourth separator on the battery cell. In this way, the working rhythm of each processing component can be ensured, and the patch efficiency of the battery cell film patching equipment of the embodiment of the present application can be greatly improved.

[0084] like Figures 4 to 6 As shown, optionally, the spacer tidying mechanism 4 includes a supporting plate 41 and four tidying components 42, wherein: the four tidying components 42 are arranged on the supporting plate 41, the four tidying components 42 together form a tidying space for accommodating the spacer, and the four tidying components 42 are respectively used to tidy one side edge of the spacer, so as to realize the position correction of the spacer.

[0085] The spacer is a thin sheet structure. If the regularization component 42 is directly set on the upper surface of the support plate 41, when there is a gap between the regularization component 42 and the upper surface of the support plate 41, the spacer is easily stuck in the gap, resulting in regularization failure or even damage to the spacer. In order to ensure that the regularization component 42 can smoothly implement the regularization of the spacer, optionally, a regularization avoidance groove 43 that penetrates the support plate 41 is provided at the position corresponding to each regularization component 42 on the support plate 41. The regularization component 42 includes a regularization cylinder 421 and a regularization block 422, wherein the regularization cylinder 421 is set on the upper surface or the lower surface of the support plate 41, the regularization block 422 is connected to the driving end of the regularization cylinder 421 and is located in the regularization avoidance groove 43, and the regularization cylinder 421 is used to drive the regularization block 422 to translate, thereby driving the regularization block 422 to implement regularization of the corresponding side of the spacer.

[0087] When the separator conveying mechanism 3 conveys the separator to the back film tearing station E, the first horizontal driving module 51 and the first lifting driving module 52 cooperate to drive the first clamping jaw assembly 54 to translate and lift, so that the first clamping jaw assembly 54 clamps the tearing end of the release film on the lower surface of the separator. Then, the first rotating driving module 53 drives the first clamping jaw assembly 54 to rotate downward, and at the same time, the separator conveying mechanism 3 pulls the separator upward, so that the release film on the lower surface of the separator is separated from the separator.

[0088] The first horizontal driving module 51 and the first lifting driving module 52 can both adopt various types of linear modules, such as linear modules composed of motors, screws, and screw nuts, etc. Similarly, the first rotating driving module 53 can adopt various types of rotating driving modules capable of driving the first clamping jaw assembly 54 to rotate up and down.

[0089] like Figure 8 As shown, optionally, the front film tearing mechanism 6 includes a second horizontal driving module 61, a second lifting driving module 62, a second rotating driving module 63 and a second clamping jaw assembly 64, wherein: the second lifting driving module 62 is connected to the movable part of the second horizontal driving module 61, the second rotating driving module 63 is connected to the second lifting driving module 62, and the second clamping jaw assembly 64 is connected to the second rotating driving module 63.

[0090] When the battery cell with the diaphragm attached reaches the front film tearing station C, the second horizontal drive module 61 and the second lifting drive module 62 cooperate to drive the second clamping jaw assembly 64 to translate and lift, so that the second clamping jaw assembly 64 clamps the tearing end of the release film on the upper surface of the diaphragm on the battery cell. Then, the second rotary drive module 63 drives the second clamping jaw assembly 64 to rotate upward. At the same time, the second horizontal drive module 61 and the second lifting drive module 62 cooperate to drive the second clamping jaw assembly 64 to pull the second clamping jaw assembly 64 obliquely upward, so that the release film on the upper surface of the diaphragm is separated from the diaphragm.

[0091] The second horizontal driving module 61 and the second lifting driving module 62 can both adopt various types of linear modules, such as linear modules composed of motors, screws, and screw nuts, etc. Similarly, the second rotating driving module 63 can adopt various types of rotating driving modules capable of driving the first clamping jaw assembly 54 to rotate up and down.
