DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will describe the preferred embodiments of the present utility model with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not used to limit the protection scope of the present utility model. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.

[0023] It should be noted that in the description of the present utility model, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the relevant devices or components must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, ordinal numbers such as "first", "second", etc. are only for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] Furthermore, in order to more clearly show the core technical solution of the present utility model, the description of the known structure of the driving device is omitted in the following description. However, this omission is only for the convenience of description and does not mean that the driving device can be without these structures.

[0026] As Figure 1-2 shown, the present utility model provides a film covering tooling for a blade battery cell, including: a frame 1; a feeding tray 2, which is arranged on the frame 1 in a liftable manner. The feeding tray 2 has a V-shaped supporting surface with an upward opening to carry the blade battery cell 3 to be coated. The V-shaped supporting surface with an upward opening can place blade battery cells 3 of different models, and the two V-shaped supporting surfaces will hold the blade battery cell 3 to prevent it from falling, and no additional fixing device is required to fix the blade battery cell 3. The clamping device 4 is configured to clamp and rotate the blade battery cell 3. The film unwinding mechanism 5 is arranged on the frame 1 and has a blue film for coating the blade battery cell 3. When the blue film abuts against the blade battery cell 3, the clamping device 4 clamps and drives the blade battery cell 3 separated from the feeding tray 2 to rotate, so as to wrap the blue film on the blade battery cell 3.

[0027] In order to facilitate the placement and removal of the blade battery cell 3 and not interfere with the film covering process, the feeding tray 2 is arranged on the frame 1 in a liftable manner. The initial position of the feeding tray 2 is the feeding position. When feeding, the blade battery cell 3 is placed on the feeding tray 2, and then the feeding tray 2 rises to the position to be clamped. After the blade battery cell 3 is clamped by the clamping device 4, the feeding tray 2 descends to the feeding position to prevent interference with the film covering process. After the blade battery cell 3 is completely coated, the feeding tray 2 rises to the position to be clamped to receive the blade battery cell 3, and then descends to the feeding position, which is convenient for the staff to take it out.

[0028] The lifting of the feeding tray 2 is driven by a first driving device, which can be a cylinder. When lifting is required, an operator presses the push button, and the feeding tray 2 can be lifted from the feeding position to the clamping position. When discharging is required, the operator presses the lowering button.

[0029] Compared with pure manual film covering, in this embodiment of the film covering tooling, the part using mechanical devices for film covering increases. The film covering process is basically carried out by the clamping device for clamping and rotating film covering, without much manual labor, and the efficiency and yield of film covering are higher. Compared with the existing multi-roller control system and servo control system, the film covering tooling in this embodiment has a simple structure and low cost, and is compatible with different models of blade-shaped battery cells, which is more suitable for small-batch production requirements. Therefore, the utility model solves the problem that both manual film covering and existing film covering equipment in the prior art are inconvenient to operate.

[0030] Further, as Figure 1-2 shown, in order to facilitate the placement and removal of the blade-shaped battery cell 3, the film covering tooling further includes: a support sliding table 6, which is slidably arranged on the frame 1. The clamping device 4 is arranged on the support sliding table 6. After the support sliding table 6 slides, it is used to form an avoidance space above the feeding tray 2 to facilitate the placement and removal of the blade-shaped battery cell 3. The support sliding table 6 can slide in any direction as long as an avoidance space can be formed. In order to improve the space utilization rate of the tooling, the support sliding table 6 is arranged to slide towards the unwinding mechanism 5.

[0031] Before placing the blade-shaped battery cell 3 on the feeding tray 2 and after the blade-shaped battery cell 3 is covered and placed on the feeding tray 2, the support sliding table 6 is made to slide towards the unwinding mechanism 5 to vacate the space above the feeding tray 2, facilitating the operator to place or remove the blade-shaped battery cell 3.

[0032] A first lead screw is arranged on the frame 1, and a slider is arranged on the lead screw. The support sliding table 6 is arranged on the slider. After the first lead screw rotates, it drives the slider to slide, and then drives the support sliding table 6 to slide. The first lead screw is driven by a second driving device, which can be a drill or a motor, etc. A slide rail parallel to the first lead screw is respectively arranged on both sides of the feeding tray 2. The support sliding table 6 has a sliding part cooperating with these two slide rails, and the arrangement of the slide rails makes the sliding of the support sliding table 6 more stable.

[0033] As Figure 2-3 shown, the clamping device 4 includes a clamp jaw 7 for clamping the blade-shaped battery cell 3 and a hand wheel 8 for driving the clamp jaw 7 to rotate. As Figure 3As shown in the figure, the clamping jaws 7 include: a first clamping block 9 and a second clamping block 10 disposed on both sides of the blade-shaped battery cell 3 along the clamping direction. The first clamping block 9 is slidably disposed on the bracket 11 along the clamping direction. A driving device 13 is provided on the bracket 11. After the output end of the driving device 13 extends out, it is used to push the first clamping block 9 towards the second clamping block 10. The driving device 13 can be a cylinder. When it is necessary to clamp the blade-shaped battery cell 3, the operator presses the clamping button. When it is necessary to release the blade-shaped battery cell 3, the operator presses the release button.

[0034] When the blade-shaped battery cell 3 is in the position to be clamped, the first clamping block 9 and the second clamping block 10 are located on both sides of the blade-shaped battery cell 3 along the clamping direction. After the operator rotates the first clamping block 9 and the second clamping block 10 to align with the side surface of the blade-shaped battery cell 3, the operator presses the clamping button. The output end of the driving device 13 extends out and pushes the first clamping block 9 towards the second clamping block 10, thereby clamping the blade-shaped battery cell 3. After the blade-shaped battery cell 3 is completely coated, the operator presses the release button. The output end of the driving device retracts, and the blade-shaped battery cell 3 falls onto the feeding tray 2 at the position to be clamped.

[0035] The bracket 11 is rotatably disposed on the frame 1 through a first rotating shaft 12, and the second clamping block 10 is rotatably disposed on the frame 1 through a second rotating shaft 14. The handwheel 8 is disposed on the first rotating shaft 12 or the second rotating shaft 14. Assuming that the handwheel 8 is disposed on the first rotating shaft 12, after the blade-shaped battery cell 3 is clamped, the operator rotates the handwheel 8, and drives the blade-shaped battery cell 3 to rotate through the first rotating shaft 12.

[0036] If only the handwheel 8 rotates to drive the blade-shaped battery cell 3 to rotate, a dislocation will occur between the first clamping block 9 and the second clamping block 10, resulting in the blade-shaped battery cell 3 falling off. For this reason, the clamping device 4 further includes a transmission assembly. The transmission assembly is used to transmit the driving torque of the handwheel 8 to the second rotating shaft 14 or the first rotating shaft 12 that is not connected to the handwheel 8. The transmission assembly includes a transmission shaft 27, transmission wheels 28 and transmission belts 29. The axial direction of the transmission shaft 27 is parallel to the clamping direction. Transmission wheels 28 are provided at both ends of the transmission shaft 27, on the first rotating shaft 12 and on the second rotating shaft 14. Transmission belts 29 are provided between two transmission wheels 28 located on the same side of the transmission shaft 27 along the clamping direction.

[0037] A first transmission wheel is arranged on the first rotating shaft 12, a fourth transmission wheel is arranged on the second rotating shaft 14, and a second transmission wheel and a third transmission wheel are respectively arranged at both ends of the transmission shaft 27. The first transmission wheel and the second transmission wheel are located on the same side of the transmission shaft 27 along the clamping direction, the third transmission wheel and the fourth transmission wheel are located on the same side of the transmission shaft 27 along the clamping direction, a first transmission belt is arranged between the first transmission wheel and the second transmission wheel, and a second transmission belt is arranged between the third transmission wheel and the fourth transmission wheel. Assuming that the handwheel 8 is arranged on the first rotating shaft 12, the driving torque of the handwheel 8 is transmitted to the second rotating shaft 14 through the first transmission wheel, the first transmission belt, the second transmission wheel, the transmission shaft 27, the third transmission wheel, the second transmission belt, and the fourth transmission wheel on the first rotating shaft 12, so that the first rotating shaft 12 and the second rotating shaft 14 rotate synchronously, preventing misalignment between the first clamping block 9 and the second clamping block 10.

[0038] As Figure 3 shown, on the sides of the first clamping block 9 and the second clamping block 10 facing the blade battery cell 3, fixing blocks 15 are detachably arranged, and fixing holes 16 for accommodating the positive and negative electrode posts protruding from both side surfaces of the blade battery cell 3 are arranged on the fixing blocks 15. When clamping blade battery cells 3 of different specifications, different fixing blocks 15 can be selected and installed on the first clamping block 9 and the second clamping block 10. The method in this embodiment can be compatible with different blade battery cells 3, and has a simple structure and is easy to operate.

[0039] As Figure 1-2 shown, in order to facilitate the clamping device to clamp the blade battery cell 3, the film covering tooling further includes: a limiting block 17, the limiting block 17 is arranged on the frame 1, the limiting block 17 and the second clamping block 10 are located on the same side of the feeding tray 2 along the clamping direction, the surface of the limiting block 17 in contact with the blade battery cell 3 is a limiting surface, and the limiting surface of the limiting block 17 is used to limit the placement position of the blade battery cell 3 along the clamping direction, and the limiting surface is flush with the clamping surface of the second clamping block 10.

[0040] When the staff places the blade battery cell 3 on the feeding tray 2, the position of the blade battery cell 3 may be deviated, which is not convenient for the first clamping block 9 and the second clamping block 10 to clamp. Therefore, a limiting block 17 is arranged on the frame 1. After the blade battery cell 3 is placed on the feeding tray 2, the staff pushes the blade battery cell 3 until it abuts against the limiting surface of the limiting block 17. Since the limiting surface is flush with the clamping surface of the second clamping block 10, therefore, no matter what specification the blade battery cell 3 for film covering is, one of its sides is always flush with the clamping surface of the second clamping block 10. When the clamping device clamps it later, only the first clamping block 9 needs to be pushed towards the second clamping block 10.

[0041] As Figure 2 and Figure 4As shown, the unwinding mechanism 5 includes a bearing 19 provided on the frame 1 and an unwinding shaft 20 rotatably provided on the bearing 19. Among them, the blue film is wound around the unwinding shaft 20. After the blade cell 3 is clamped, the blue film is manually pasted onto the side of the blade cell 3, and then the handwheel 8 is rotated, and the blade cell 3 rotates accordingly to achieve the wrapping of the blade cell 3.

[0042] In order to reduce the friction between the unwinding shaft 20 and the bearing 19, there are four bearings 19 in this embodiment. Every two bearings 19 are rotatably provided on both sides of the frame 1 along the clamping direction, and the unwinding shaft 20 is placed between the two bearings, converting the sliding friction between the shaft and the bearing into rolling friction.

[0043] The blue film is wound around the core. During use, the unwinding shaft 20 is inserted into the core and then placed on the frame 1. For blue films of different specifications, the diameters of their cores are different. In order to be compatible with cores of different diameters, the film covering tooling further includes a tapered sleeve 21. A through hole 22 allowing the unwinding shaft 20 to pass through is provided in the tapered sleeve 21. In the assembled state, the tapered surface of the tapered sleeve 21 can extend into the core of the blue film; mounting holes 23 are also provided on the tapered sleeve 21, and the mounting holes 23 are configured to allow a connecting member to pass through them so as to detachably fix the tapered sleeve 21 to the unwinding shaft 20.

[0044] The radius of the tapered surface gradually increases. By extending the tapered surface into the core, cores of different diameters can be adapted. When replacing the core, first remove the unwinding shaft 20, then remove the tapered sleeve 21 thereon, then insert the unwinding shaft 20 into the new core, and finally install the tapered sleeve 21 on the unwinding shaft 20 through the mounting holes 23. After installation, the tapered surface of the tapered sleeve 21 is inserted into the core. In this embodiment, cores of different diameters can be compatible through the tapered sleeve. Compared with the air shaft mechanism, this embodiment has a greater core diameter compatibility ability, and the structure is simple and easy to operate.

[0045] Further, as Figure 5 shown, the film covering tooling further includes: a friction plate 24 provided on the unwinding shaft 20; a pressure adjusting member 25 provided on the frame 1 and located on the side of the friction plate 24 away from the unwinding shaft 20, which is configured to control the friction plate 24 to approach or move away from the unwinding shaft 20 by rotating forward or backward. The pressure adjusting member 25 can adjust the pressure between the friction plate 24 and the unwinding shaft 20, and then change the frictional force to adjust the unwinding tension.

[0046] The pressure adjusting member 8 is a combination of a lead screw and a nut. The lead screw is fixed on the frame, and the nut is used to press on the side of the friction plate 7 away from the unwind reel 502. After the nut rotates forward on the lead screw, the friction plate 7 presses tightly against the unwind reel 502, the pressure between the friction plate 7 and the unwind reel 502 increases, and thus the frictional force increases. After the nut rotates reversely on the lead screw, the friction plate 7 moves relatively away from the unwind reel 502, the pressure between the friction plate 7 and the unwind reel 502 decreases, and thus the frictional force decreases. By adjusting the frictional force between the friction plate 7 and the unwind reel 502 to control the unwind tension, compared with the servo control system, the method of this embodiment is more convenient.

[0047] Further, in order to fit the outer surface of the unwind reel 20, the friction plate 7 is arranged in an arc shape. In order to make the friction plate 7 receive uniform force, the film laminating tooling further includes: a pressing plate 26, one end of the pressing plate 26 is rotatably arranged on the frame 1, and a pressure adjusting member 25 is arranged on the side of the other end away from the unwind reel 20. An arc surface is arranged on the pressing plate 26, the friction plate 7 is placed in the arc surface, the friction plate 24 is located between the pressing plate 26 and the unwind reel 20, and after the pressure adjusting member 25 rotates forward or reversely, it drives the pressing plate 26 to approach or move away from the unwind reel 20.

[0048] Further, as Figure 1-2 shown, the film laminating tooling further includes: a separator paper recovery shaft 30, the separator paper recovery shaft 30 is arranged on one side of the unwind reel 20 and is used to recover the separator paper on the blue film. A recovery handwheel is arranged on the separator paper recovery shaft 30, and by rotating the recovery handwheel, the separator paper is wound around the separator paper recovery shaft 30.

[0049] A working process of the film laminating tooling for the blade-shaped battery cell in this embodiment is as follows: The feeding tray 2 is at the feeding position. After the staff places the blade-shaped battery cell 3 on the feeding tray 2, the blade-shaped battery cell 3 is pushed until it contacts the limiting surface, and the driving support slide 6 drives the clamping device 4 to slide above the blade-shaped battery cell 3; Press the push button, and the feeding tray 2 rises from the feeding position to the position to be clamped; After the staff rotates the first clamping block 9 and the second clamping block 10 to align with the side surface of the blade-shaped battery cell 3, press the clamping button, the output end of the driving device 13 extends out, and the first clamping block 9 is pushed towards the second clamping block 10 to clamp the blade-shaped battery cell 3; Press the lowering button, and the feeding tray 2 descends to the feeding position; Manually paste the blue film on the side surface of the blade-shaped battery cell 3, and then rotate the handwheel 8, and the blade-shaped battery cell 3 rotates accordingly to achieve the wrapping of the blade-shaped battery cell 3. After the wrapping is completed, manually cut the blue film, press the push button, and the feeding tray 2 rises from the feeding position to the position to be clamped; Press the release button, the output end of the driving device retracts, and the blade-shaped battery cell 3 falls on the feeding tray 2 at the position to be clamped; Press the lowering button, and the feeding tray 2 descends to the feeding position; The driving support slide 6 drives the clamping device 4 to slide towards the unwind mechanism 5, and then the blade-shaped battery cell 3 is taken off from the feeding tray 2.

[0050] So far, the technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easily understood by those skilled in the art that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present utility model.
