They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] This embodiment provides a battery bottom film insertion device, which can stably press the bottom film into the battery casing 200, improving the uniformity of bottom film placement and ensuring the overall performance of the battery. As shown in Figures 1-3, the battery bottom film insertion device includes a mounting component 10, a bottom film processing component 20, and a fixture processing component 30. The mounting component 10 has an upper plate 11 and a lower plate 12 spaced apart in the vertical direction. The bottom film processing component 20 includes a first driving component 21, a pressing component 22, and a bottom film positioning component 23. The first driving component 21 is mounted on the upper plate 11, the pressing component 22 is connected to the output end of the first driving component 21, and the bottom film positioning component 23 is installed through the upper plate 11 to form a bottom film channel 233 extending in the vertical direction. The fixture processing component 30 includes a second driving component. The second drive member 31 is mounted on the lower plate 12, and the fixture 32 is located below the bottom film positioning member 23 and connected to the output end of the second drive member 31. The second drive member 31 can drive the fixture 32 to reciprocate through the lower plate 12 in the up-down direction so that the top of the battery case 200 can abut against or move away from the lower side of the upper plate 11. The fixture 32 is used to accommodate the battery case 200. The first drive member 21 can drive the pressing member 22 to move in the up-down direction so that when the battery case 200 abuts against the lower side of the upper plate 11, the bottom film is pressed into the bottom of the battery case 200 from the bottom film channel 233.

[0040] In the above-mentioned battery bottom film insertion device, the bottom film is placed on the bottom film positioning member 23. When the output end of the second drive member 31 retracts, the battery case 200 is placed into the fixture 32. Then, the second drive member 31 drives the fixture 32 and the battery case 200 to move upward together until the top of the battery case 200 abuts against the lower side of the upper plate 11. At this time, the battery case 200 will no longer shift or shake. Then, the first drive member 21 drives the pressing member 22 downward to press the bottom film down so that the bottom film enters the battery case 200 through the bottom film channel 233 until the pressing member 22 presses the bottom film to the bottom of the battery case 200. The above steps make the bottom film insertion process more mechanized. At the same time, the second drive member 31 drives the fixture 32 to rise so that the battery case 200 is fixed after abutting, ensuring that the battery case 200 is absolutely stationary during the bottom film insertion process, thereby ensuring the accuracy and stability of the bottom film insertion and improving the overall performance of the battery.

[0041] Optionally, as shown in Figure 3, a positioning groove 115 is provided on the side of the lower plate 12 facing the upper plate 11, and the positioning groove 115 is adapted to the cross-sectional shape of the battery casing 200. Thus, during the upward movement of the fixture 32, the positioning groove 115 can play a certain radial and circumferential limiting role for the fixture 32.

[0042] Optionally, as shown in Figure 4, the fixture 32 has a first receiving groove 321 that is consistent with the shape of the battery case 200. After the battery case 200 is placed, the bottom of the battery case 200 abuts against the bottom of the first receiving groove 321.

[0043] Optionally, referring to Figures 3 and 4, the middle of the battery casing 200 is recessed downward to form a convex part, and a relief groove 322 is formed at the bottom of the first receiving groove 321 to avoid the convex part. Due to the presence of the convex part at the bottom of the battery casing 200, the height of the convex part will vary slightly between different battery casings 200. If the relief groove 322 is not provided, the battery casing 200 will be unstable. The above-mentioned setting avoids this problem.

[0044] Optionally, as shown in Figures 1, 3, and 4, the fixture processing assembly 30 further includes a stabilizing member 33. The stabilizing member 33 includes a base 331 and a stabilizing part 332. The base 331 is installed on the upper side of the lower plate 12, and the fixture 32 can pass through the base 331. The base 331 has a certain thickness and plays a guiding role for the fixture 32. The stabilizing part 332 is connected to the upper side of the base 331 and extends in the vertical direction. The inner sidewall of the stabilizing part 332 is constructed with a first guide wall 3321 located at the upper part and a second guide wall 3322 located at the lower part. The first guide wall 3321 is adapted to the shape of part of the peripheral sidewall of the battery case 200, and the second guide wall 3322 is adapted to the shape of part of the peripheral sidewall of the fixture 32. With the above settings, on the one hand, since the height of the first receiving groove 321 is limited, the first guide wall 3321 plays a role in preventing the battery case 200 from tipping over during the upward movement of the fixture 32, while the second guide wall 3322 can extend the guiding length of the fixture 32, so that the fixture 32 moves up and down with accurate direction.

[0045] Optionally, the outer periphery of the fixture 32 is a circular surface. Due to the thickness of the fixture 32, the outer diameter of the fixture 32 must be larger than the outer diameter of the battery case 200. A stepped surface is formed between the first guide wall 3321 and the second guide wall 3322, which can limit the stroke of the second drive member 31 in case of emergencies, and prevent the output end of the second drive member 31 from extending too far, causing the battery case 200 to be squeezed.

[0046] Optionally, as shown in Figures 1 and 4, the cross-section of the stabilizing part 332 is semi-annular, and hand clearance grooves 3323 are provided on both sides. With the above configuration, it is possible to place the battery case 200 into the first receiving groove 321 while the fingers are holding the battery case 200, thereby improving the stability of placing and removing the battery case 200.

[0047] Optionally, as shown in Figure 3, the upper plate 11 has a second receiving groove 111, and the bottom of the second receiving groove 111 has a through hole. The bottom film positioning member 23 includes a support part 231 and a channel wall 232. The support part 231 is annular and is housed in the second receiving groove 111. The channel wall 232 forms a bottom film channel 233 therein, and the channel wall 232 is connected to the support part 231 and passes through the through hole. Through the above arrangement, the support part 231 supports the bottom film, the channel wall 232 forms the bottom film channel 233, and at the same time, it plays a certain guiding role in the downward pressure of the pressing member 22. Meanwhile, the second receiving groove 111 limits the position of the bottom film to prevent the bottom film from shifting.

[0048] Optionally, as shown in Figures 1 and 3, the top inner corner of the support portion 231 is rounded. With the above configuration, when the pressing member 22 presses down, the bottom film contacts the top inner corner of the support portion 231, and the bottom film will first become an inverted trapezoid. As the pressing member 22 fully enters, the bottom film becomes a U-shape. During this process, the top inner corner of the support portion 231 will not scratch the bottom film.

[0049] Optionally, as shown in Figures 1 and 3, the upper plate 11 is also provided with a pick-and-place slot 113 communicating with the second receiving slot 111, and part of the support part 231 is located in the pick-and-place slot 113. Since the bottom film positioning part 23 and the upper plate 11 are two independent parts, and after installation, the support part 231 is embedded in the second receiving slot 111, it is difficult to remove it from the top if it is to be replaced. The function of the pick-and-place slot 113 is to facilitate the removal of the bottom film positioning part 23 from the top.

[0050] Optionally, as shown in Figures 1 and 3, a mounting hole 114 is provided on the inner wall of the take-up slot 113. The locking member is installed on the side wall of the take-up slot 113, passes through the mounting hole 114, and abuts against the side wall of the support part 231. Thus, the bottom film positioning member 23 is fixed by abutment, and the locking member can be removed when removing it. Further, the locking member can be a screw.

[0051] Optionally, as shown in Figure 3, a circular weight-reducing groove 221 is provided on the lower side of the pressing member 22 to reduce weight and lower the load on the first driving member 21.

[0052] Optionally, the first driving element 21 and the second driving element 31 are driving elements that can output linear motion, such as cylinders or linear motors, and are not limited here.

[0053] Optionally, at least two fixture processing components 30 and bottom film processing components 20 are provided in a one-to-one correspondence. This allows for the simultaneous insertion of the bottom film into two battery casings 200, improving work efficiency.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
