Description

Technical Field

[0001] This application relates to the field of battery testing technology, and in particular to a test fixture for pouch batteries. Background Technology

[0002] During the production process of pouch batteries, pouch battery test racks are required to test the pouch batteries.

[0003] A pouch battery test rack includes a frame and a test device mounted on the frame. The test device typically includes two test clamps for holding the pouch battery tabs and electrically connected to the test system. Pouch batteries generally come in two types: a first pouch battery with both tabs on the same side and a second pouch battery with both tabs on opposite sides. Therefore, different test devices are required depending on the type of pouch battery. When testing a first pouch battery, a test device with both test clamps on the same side should be used; when testing a second pouch battery, a test device with both test clamps on opposite sides should be used.

[0004] Neither of the two testing devices mentioned above has the capability to test both the first and second pouch batteries. Utility Model Content

[0005] This application provides a pouch battery test fixture, which has a test device capable of testing both a first pouch battery and a second pouch battery.

[0006] This application provides a soft-pack battery test fixture, which adopts the following technical solution:

[0007] A pouch battery test fixture includes a frame and a test device. The frame has a mounting partition for arranging the test device. The test device includes two test clamps for holding the tabs of the pouch battery, a first clamping seat mounted on the mounting partition, and a second clamping seat mounted on the mounting partition and arranged relative to the first clamping seat. The bottom of the test clamps has a sliding structure. The first clamping seat has a first sliding groove that cooperates with the sliding structure, and the second clamping seat has a second sliding groove that cooperates with the sliding structure.

[0008] By adopting the above technical solution, when testing a first pouch battery with its two tabs located on the same side, two test clamps are mounted on the first clamping seat and clamp the two tabs of the first pouch battery, enabling the testing device to test the first pouch battery. When testing a second pouch battery with its two tabs located on opposite sides, two test clamps are mounted on the first clamping seat and the second clamping seat respectively, clamping the two tabs of the second pouch battery, enabling the testing device to test both pouch batteries. Therefore, the above-mentioned pouch battery test rack can, by adjusting the installation position of the two test clamps, have the function of testing both the first and second pouch batteries.

[0009] Optionally, the second clamping seat is slidably mounted on the mounting partition along the length direction of the pouch battery. The second clamping seat includes a second top plate that abuts against the top surface of the mounting partition, a second bottom plate that abuts against the bottom surface of the mounting partition, and a locking bolt connecting the second top plate and the second bottom plate. The mounting partition has a sliding groove for the locking bolt to slide.

[0010] By adopting the above technical solution, the second clamping seat can adjust its position in the sliding groove according to the length of the second soft-pack battery, and can be locked to the mounting partition by the second top plate, locking bolt and second bottom plate, thereby realizing the testing of second soft-pack batteries of different lengths.

[0011] Optionally, the second clamping seat has two of the locking bolts; the sliding grooves on the mounting plate are arranged in a one-to-one correspondence with the locking bolts.

[0012] By adopting the above technical solution, when the second clamping seat slides on the top surface of the mounting plate, the cooperation of the two locking bolts, the adjusting through groove and the second base plate makes the stability of the second clamping seat during the sliding process more ideal and less prone to deflection.

[0013] Optionally, both the first sliding groove and the second sliding groove are T-shaped sliding grooves, and the sliding structure includes two L-shaped protrusions arranged symmetrically at the bottom of the test clamp.

[0014] By adopting the above technical solution, the specific construction of the first sliding groove, the second sliding groove and the sliding structure is disclosed, which makes the stability of the sliding structure when sliding in the first sliding groove / second sliding groove more ideal and reduces the probability of affecting the clamping effect due to sliding instability.

[0015] Optionally, the testing device further includes a locking mechanism for pressing the pouch battery against the mounting partition; the locking mechanism includes a locking plate, two locking rods respectively connected to both ends of the locking plate and both vertically penetrating the mounting partition, a locking nut installed at the bottom end of the locking rods, and a locking spring sleeved on the locking rods and located on the lower side of the mounting partition; one end of the locking spring abuts against the bottom surface of the mounting partition and the other end abuts against the locking nut.

[0016] By adopting the above technical solution, the specific structure of the locking mechanism is disclosed. When testing the soft-pack battery, the locking plate, locking link, locking spring and locking nut work together to make the locking plate press the soft-pack battery tightly, which helps to improve the stability of the soft-pack battery during the test.

[0017] Optionally, the locking plate is a resilient rubber plate.

[0018] By adopting the above technical solution, the locking plate is made of rubber, and because rubber has good elasticity, the probability of the locking mechanism scratching the soft-pack battery during the locking process is reduced.

[0019] Optionally, the mounting partition has an abutment protrusion on the side near the first clamping seat for the end of the pouch battery to abut against.

[0020] By adopting the above technical solution, when the soft-pack battery is placed in the testing device, the abutting protrusion can be used for the end of the soft-pack battery to abut against, thereby making it easier to place the soft-pack battery upright. After the locking mechanism locks the soft-pack battery, the test clamp can more easily clamp the tab of the soft-pack battery.

[0021] Optionally, multiple sets of the test devices are arranged at intervals along the length of the top surface of the mounting partition.

[0022] By adopting the above technical solution and setting multiple sets of testing devices on the mounting partition, the soft-pack battery test rack can test multiple soft-pack batteries simultaneously, which helps to improve the efficiency of the soft-pack battery test rack in testing soft-pack batteries.

[0023] Optionally, the mounting partition is equipped with a cable management rack on its side wall along the length direction; the cable management rack includes a mounting plate installed on the side wall of the mounting partition and a cable management plate connected to the mounting plate; the cable management plate is provided with cable management grooves at intervals along the length direction.

[0024] By adopting the above technical solution, the specific structure of the cable management rack is disclosed. The cable management rack enables the wires connecting the test clips to be arranged in an orderly manner during the testing process of the soft-pack battery test rack.

[0025] Optionally, the cable management rack has two cable management plates, which are respectively connected to the upper and lower edges of the mounting plate.

[0026] By adopting the above technical solution, the cable management rack has two cable management plates, which can limit and clamp a section of wire, thus helping to improve the cable management effect of the cable management rack.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. A soft-pack battery test fixture, which can perform tests on both a first soft-pack battery and a second soft-pack battery by adjusting the installation positions of two test clamps;

[0029] 2. The second clamping seat in the testing device is slidably arranged on the mounting partition, and the second clamping seat can be locked on the mounting partition by the second top plate, locking bolt and second bottom plate, so that the testing device can test the second soft pack batteries of different lengths and sizes, which helps to improve the applicability of the testing device.

[0030] 3. The testing device is equipped with a locking mechanism. The locking plate of the locking mechanism can press the pouch battery firmly onto the mounting partition, so that the pouch battery will not move during the test, which helps to ensure the stability of the test.

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] This application discloses a test fixture for pouch batteries.

[0040] Reference Figure 1 A soft-pack battery test rack includes a frame 1 and multiple test devices 2 mounted on the frame 1.

[0041] Reference Figure 1 The frame 1 includes a metal frame 11 and multiple horizontally arranged mounting partitions 12 mounted on the metal frame 11. The mounting partitions 12 are arranged vertically at intervals, and the testing devices 2 are mounted on the top surface of each mounting partition 12. In this embodiment, there are four mounting partitions 12, each with eight testing devices 2, and the eight testing devices 2 located on the same mounting partition 12 are spaced apart along the length of the mounting partition 12. Four casters 13 are mounted on the bottom of the metal frame 11. In this embodiment, the casters 13 are casters with brakes to facilitate movement and locking of the frame 1.

[0042] Reference Figure 1 and Figure 2 The testing device 2 includes two test clamps 21 for holding the tabs of a pouch battery, a first clamping seat 22 mounted on a mounting partition 12, a second clamping seat 23 mounted on the mounting partition 12 and arranged relative to the first clamping seat 22, and a locking mechanism 24 for pressing the pouch battery against the mounting partition 12. Both test clamps 21 are detachably mounted on the first clamping seat 22 and the second clamping seat 23.

[0043] Reference Figure 2The first clamping seat 22 is a square plate structure and is mounted on the mounting partition 12 with screws. A first sliding groove 221 is formed at the top of the first clamping seat 22, penetrating both side walls of the first clamping seat 22 and parallel to the length direction of the mounting partition 12. In this embodiment, the first sliding groove 221 is a T-shaped groove.

[0044] Reference Figure 2 and Figure 3 The second clamping seat 23 is slidably mounted on the mounting partition 12 along the length of the pouch battery. The second clamping seat 23 includes a second top plate 233 abutting the top surface of the mounting partition 12, a second bottom plate 234 abutting the bottom surface of the mounting partition 12, and a locking bolt 232 connecting the second top plate 233 and the second bottom plate 234. The second top plate 233 has a through hole for the locking bolt 232 to pass through, and the second bottom plate 234 has a threaded hole for engaging with the locking bolt 232. The mounting partition 12 has sliding grooves 121 for the locking bolts 232 to slide. The second clamping seat 23 has two locking bolts 232. Therefore, the mounting partition 12 has two sliding grooves 121 corresponding to each second clamping seat 23. The two sliding grooves 121 are arranged one-to-one with the locking bolts 232 on the second clamping seat 23.

[0045] Reference Figure 2 and Figure 3 The second top plate 233 is a square plate structure. A second sliding groove 231 is provided on the top of the second top plate 233, penetrating both side walls of the second top plate 233 and parallel to the length direction of the mounting partition 12. In this embodiment, the second sliding groove 231 is a T-shaped groove, and the cross-sectional dimensions of the second sliding groove 231 are consistent with the cross-sectional dimensions of the first sliding groove 221.

[0046] Reference Figure 2 and Figure 4 The bottom of the test clip 21 has a sliding structure for engaging with the first sliding groove 221 / second sliding groove 231. The sliding structure consists of two symmetrically arranged L-shaped protrusions 211 on the bottom of the test clip 21. Therefore, the two test clips 21 can slide within the first sliding groove 221 of the first clamping seat 22 or within the second sliding groove 231 of the second clamping seat 23. The distance between the two L-shaped protrusions 211 in the sliding structure is sufficient for the screws of the first clamping seat 22 and the locking bolts 232 of the second clamping seat 23 to pass through.

[0047] Reference Figure 2 and Figure 5The locking mechanism 24 is located on one side near the first clamping seat 22.

One end of the locking spring 243 abuts against the bottom surface of the mounting partition 12, and the other end abuts against the locking nut 244. The locking plate 241 is an elastic rubber plate, and both ends of the locking plate 241 have through holes for arranging the locking rods 242. The top of the locking rods 242 has a locking head 245 arranged on the upper side of the locking plate 241, and the outer diameter of the locking head 245 is larger than the diameter of the through holes on the locking plate 241. To facilitate lifting the locking plate 241, a lifting handle 246 is provided in the middle of the top surface of the locking plate 241.

[0048] Reference Figure 2 In order to facilitate the proper placement of the pouch battery in the test device 2, the mounting plate 12 is provided with an abutment protrusion 3 on the side near the first clamping seat 22 for the end of the pouch battery to abut against.

[0049] Reference Figure 1 and Figure 6 A cable management rack 4 is installed on the side wall of the mounting partition 12 along its length. The cable management rack 4 includes a mounting plate 41 mounted on the side wall of the mounting partition 12 and two cable management plates 42 connected to the mounting plate 41. The cable management plates 42 have cable management grooves 421 spaced apart along their length. The mounting plate 41 is mounted on the mounting partition 12 with screws. The two cable management plates 42 are respectively connected to the upper and lower edges of the mounting plate 41. The cable management rack 4 can clamp and guide a section of the wires in the testing device 2, thereby facilitating the organization of the wires on the soft-pack battery testing rack.

[0050] Combination Figures 1 to 6 The implementation principle of a soft-pack battery test rack in this application embodiment is as follows: When testing a first soft-pack battery with two tabs located on the same side, two test clips 21 are installed on a first clamping seat 22 and clamp the two tabs of the first soft-pack battery, so that the test device 2 can test the first soft-pack battery; when testing a second soft-pack battery with two tabs located on opposite sides, two test clips 21 are respectively installed on a first clamping seat 22 and a second clamping seat 23, and the two test clips 21 clamp the two tabs of the second soft-pack battery, so that the test device 2 can test the second soft-pack battery.
