Description

Technical Field

[0001] This utility model relates to a battery testing device, and more particularly to a positioning device for a soft-pack battery. Background Technology

[0002] Existing pressure short-circuit testing mechanisms typically consist of a pressure cylinder mechanism and a battery puncture mechanism. The process involves manually placing the incoming batteries into the testing station, clamping them with the pressure cylinder to apply pressure, and then puncturing them using the battery puncture mechanism for testing. After testing, the batteries are manually removed. However, when batch testing multiple batteries, existing testing mechanisms often fail to accurately align each battery because they are not pre-positioned. This leads to poor contact with misaligned batteries during testing, resulting in failed tests, high NG rates, high rework rates, and reduced production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a positioning device for soft-pack batteries, which can automatically perform batch positioning of soft-pack batteries before insulation testing, thereby improving the accuracy of insulation testing and thus improving production efficiency.

[0004] To achieve the above objectives, this utility model provides a soft-pack battery positioning device, including a base, a first gripper, a second gripper, a first push plate, a second push plate, a first drive cylinder, and a second drive cylinder. The first gripper and the second gripper are disposed on the base, and a clamping groove for accommodating the soft-pack battery is formed between the first gripper and the second gripper. The upper side, front side, and rear side of the clamping groove are all in communication with the outside. The first drive cylinder is disposed on the base and its output end is connected to the first push plate, so that the first push plate moves closer to or away from the front side of the clamping groove. The second drive cylinder is disposed on the base and its output end is connected to the second push plate, so that the second push plate moves closer to or away from the rear side of the clamping groove.

[0005] Compared with the prior art, this utility model sets a first gripper and a second gripper on the base, and sets a first push plate and a second push plate on the front and rear sides of the first gripper and the second gripper, respectively. Then, a first drive cylinder drives the first push plate and a second drive cylinder drives the second push plate. This allows the first push plate and the second push plate to move closer to or further away from each other on the soft-pack battery located between the two grippers. Therefore, the soft-pack battery can be completely aligned between the first push plate and the second push plate. Moreover, under one drive, multiple soft-pack batteries can be automatically batch positioned simultaneously, ensuring the accurate position of each soft-pack battery and the accurate position of all batteries relative to each other. This provides precise positioning for the subsequent gripper to pick up the battery and place it on the insulation testing station, improving the accuracy of insulation testing and thus improving production efficiency.

[0006] Specifically, the first push plate and the second push plate are located at the lower part of the front side of the clamping groove, so that the tabs of the pouch battery extend out of the front side of the clamping groove and are located above the first push plate. This avoids the first and second push plates affecting the tabs, making the structure more compact and reasonable.

[0007] Specifically, the positioning device further includes a translation drive device, which drives the machine base to translate. By providing the translation drive device, the positioning device can transfer the pouch battery to the next workstation while simultaneously positioning it, thereby shortening production time and improving work efficiency.

[0008] Specifically, the translation drive device includes a drive motor, a drive pulley, a driven pulley, and a belt. The drive pulley is connected to the output end of the drive motor. The belt is wrapped around the drive pulley and the driven pulley. The base is mounted on the belt and moves as the belt runs.

[0009] Specifically, there are two sets of driving pulleys, driven pulleys, and belts, symmetrically arranged at both ends of the machine base, with a linkage shaft connecting the two driving pulleys. This ensures that both ends of the machine base are subjected to the traction force of the translation drive device, thereby maintaining a balanced traction force and making the movement of the machine base more stable.

[0010] Specifically, the first drive cylinder and the second drive cylinder are located in the gap between two adjacent clamping slots. This makes full use of the remaining space on the base, resulting in a more compact, reasonable, and smaller positioning device.

[0011] Specifically, both the first and second grippers have multiple gripping fingers on their upper sides, with gaps between adjacent gripping fingers. These gripping fingers allow the gripping fingers of the first transfer and handling robot to pass through the gaps between adjacent fingers, thereby achieving the purpose of gripping the pouch battery between the first and second grippers and improving the ease of gripping.

[0014] Figure 3 This is a top view of the soft-pack battery positioning device of this utility model. Detailed Implementation

[0015] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0016] Please see Figures 1 to 3 The present invention relates to a soft-pack battery positioning device 1, comprising a base 11, a first gripper 12, a second gripper 13, a first push plate 14, a second push plate 15, a first drive cylinder 16, and a second drive cylinder 17. The first gripper 12 and the second gripper 13 are disposed on the base 11, forming a clamping groove 18 for accommodating the soft-pack battery between them. The upper, front, and rear sides of the clamping groove 18 are all in communication with the outside. The first drive cylinder 16 is disposed on the base 11 and its output end is connected to the first push plate 14, so that the first push plate 14 moves closer to or away from the front side of the clamping groove 18. The second drive cylinder 17 is disposed on the base 11 and its output end is connected to the second push plate 15, so that the second push plate 15 moves closer to or away from the rear side of the clamping groove 18.

[0017] Please see again Figure 3 The first push plate 14 and the second push plate 15 are located at the lower part of the front side of the clamping groove 18, so that the tabs of the soft-pack battery extend out of the front side of the clamping groove 18 and are located above the first push plate 14. This avoids the first push plate 14 and the second push plate 15 from affecting the tabs, making the structure more compact and reasonable.

[0018] Please see again Figure 3 The first drive cylinder 16 and the second drive cylinder 17 are located in the gap 19 between two adjacent clamping slots 18. This makes full use of the remaining space on the base 11, resulting in a more compact, reasonable, and smaller structure for the positioning device 1.

[0019] Please see again Figure 1 and Figure 2 Both the first gripper 12 and the second gripper 13 have multiple gripping fingers on their upper sides, with gaps between adjacent gripping fingers. These gripping fingers allow the gripping fingers of the first transfer and handling robot 3 to pass through the gaps between adjacent gripping fingers, thereby achieving the purpose of gripping the soft-pack battery between the first gripper 12 and the second gripper 13, improving the ease of gripping.

[0020] Please refer to the following: Figure 1The positioning device 1 further includes a translation drive device 20, which drives the machine base 11 to translate. By setting the translation drive device 20, the positioning device 1 can transfer the soft-pack battery to the next work station while positioning it, thereby shortening production time and improving work efficiency. The translation drive device 20 includes a drive motor 201, a drive pulley 202, a driven pulley 203, and a belt 204. The drive pulley 202 is connected to the output end of the drive motor 201. The belt 204 surrounds the drive pulley 202 and the driven pulley 203. The machine base 11 is disposed on the belt 204 and moves with the operation of the belt 204. Specifically, there are two sets of drive pulleys 202, driven pulleys 203, and belts 204, which are symmetrically arranged at both ends of the machine base 11. A linkage shaft 205 connects the two drive pulleys 202. This ensures that both ends of the base 11 are subjected to the traction force of the translation drive device 20, thereby maintaining the balance of the traction force and making the movement of the base 11 more stable.

[0021] In summary, the working principle of the utility model soft-pack battery positioning device 1 will be described in detail below.

[0022] First, after the pouch batteries are loaded and placed in the clamping slot 18, the first drive cylinder 16 and the second drive cylinder 17 are simultaneously activated, driving the first push plate 14 and the second push plate 15 to move towards each other. The first push plate 14 and the second push plate 15 push the pouch batteries between them to move and align with each other. During this process, the translation drive device 20 is activated, and the drive motor 201 drives the belt 204 to rotate, causing the belt 204 to move the machine base 11 in translation. The machine base 11 can then transport the pouch batteries towards the insulation testing station.

[0023] Compared with the prior art, this utility model, by setting a first gripper 12 and a second gripper 13 on the base 11, and setting a first pusher plate 14 and a second pusher plate 15 on the front and rear sides of the first gripper 12 and the second gripper 13 respectively, and using a first drive cylinder 16 to drive the first pusher plate 14 and a second drive cylinder 17 to drive the second pusher plate 15, allows the first pusher plate 14 and the second pusher plate 15 to move closer to or further away from the soft-pack battery located between the two grippers. Therefore, the soft-pack battery can be completely aligned between the first pusher plate 14 and the second pusher plate 15. Moreover, under one drive, multiple parallel soft-pack batteries can be automatically batch positioned simultaneously, ensuring the accurate position of each soft-pack battery and the accurate position of all batteries relative to each other. This provides precise positioning for the subsequent gripping of the robot arm to the insulation testing station, improves the accuracy of insulation testing, and thus improves production efficiency.

[0024] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model shall still fall within the scope of the present utility model.
