Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an auxiliary device for online high-current testing of side-terminal lead-acid batteries. Background Technology

[0002] Online high-current testing of lead-acid batteries is a testing technology used for quality inspection of lead-acid batteries. High-current testing can quickly detect potential defects in the manufacturing process, screen out unqualified batteries, and ensure product consistency, reliability, and safety. However, existing high-current testing machines are only suitable for top-mounted terminal batteries with terminals on the top. Current technologies use a cylinder to drive the high-current detection column vertically to press against the battery end for testing. For side-mounted terminal batteries, some solutions use online capacity testing instead of high-current testing, or install an L-shaped copper conductive component on the side end of the lead-acid battery to be tested, making it suitable for high-current testing machines. Regardless of the method used, both increase testing costs and reduce production efficiency. Therefore, the battery technology field needs to propose an auxiliary device for online high-current testing of side-mounted lead-acid batteries that can reduce testing costs and improve production efficiency. Utility Model Content

[0003] In view of the above-mentioned prior art, the present invention provides an auxiliary device for online high-current testing of side-terminal lead-acid batteries, and the main technical problem to be solved is how to reduce testing costs and improve production efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] An auxiliary device for online high-current testing of a side-terminal lead-acid battery includes a high-current detection column and a testing auxiliary box. The testing auxiliary box includes a housing, an L-shaped copper busbar, a rotating roller, and an adjusting cylinder. The upper end of the housing is provided with a first slot, and one side of the first slot is provided with an opening. One end of the L-shaped copper busbar is inserted into the opening and fits against the upper end of the first slot. The upper end of the L-shaped copper busbar is connected to the high-current detection column. The inner wall of the housing is symmetrically provided with roller mounting slots. The rotating roller is rotatably connected to the inner wall of the housing through the roller mounting slots. The side of the housing away from the opening is connected to the adjusting cylinder.

[0006] Preferably, a second slot is provided at the lower end of the opening, and one end of the L-shaped copper busbar is fitted with the second slot.

[0007] Preferably, both the first slot and the second slot are provided with connecting holes, and the L-shaped copper busbar is detachably connected to the first slot and the second slot through the connecting holes with bolts.

[0008] Preferably, the widths of the first slot and the second slot are greater than the width of the L-shaped copper busbar.

[0009] Preferably, the connecting hole is configured as an oblong hole.

[0010] Preferably, the high current detection column is detachably connected to the L-shaped copper busbar by bolts.

[0011] Preferably, a cylinder connection opening is provided at the connection between the outer casing and the adjusting cylinder, and the adjusting cylinder is detachably connected to the cylinder connection opening by bolts.

[0012] Preferably, the outer shell is configured as a hollow rectangular structure with an open lower end.

[0013] Preferably, there are several rotating rollers, and the roller mounting grooves are connected one-to-one with the two sides of the several rotating rollers, and the several rotating rollers are arranged in parallel to each other.

[0014] The beneficial effects of this utility model are as follows: By setting up a testing auxiliary box, when side-terminal lead-acid batteries need to be tested, the testing auxiliary box can be connected to an online high-current testing device via a high-current testing column for auxiliary testing. The testing auxiliary box includes a shell and an L-shaped copper busbar. The shell is fitted over the side-terminal lead-acid battery, so that the terminals of the side-terminal lead-acid battery are electrically connected to the high-current testing column above through the L-shaped copper busbar for testing. After the test is completed, the shell is disconnected from the side-terminal lead-acid battery. The process of fitting and disconnecting the shell is repeated, enabling batch testing of side-terminal lead-acid batteries using the same testing auxiliary box, improving production efficiency and reducing testing costs.

[0015] Meanwhile, the testing auxiliary box also includes an adjusting cylinder and a rotating roller. When the outer casing is fitted over the side-terminal lead-acid battery, the adjusting cylinder is activated to push the side-terminal lead-acid battery to move, ensuring that the terminal part of the side-terminal lead-acid battery is in contact with the L-shaped copper busbar. The rotating roller makes the movement of the side-terminal lead-acid battery smoother, improving the reliability of this application.

[0016] In summary, this application reduces testing costs and improves production efficiency by using an auxiliary testing box to assist in online high-current testing. Attached Figure Description

The testing auxiliary box 2 includes a housing 201, an L-shaped copper busbar 202, a rotating roller 203, and an adjusting cylinder 204. The upper end of the housing 201 is provided with a first slot 205, and one side of the first slot 205 is provided with an opening 206. One end of the L-shaped copper busbar 202 is inserted into the opening 206 and fits against the upper end of the first slot 205. The upper end of the L-shaped copper busbar 202 is connected to the high-current detection column 1. The inner wall of the housing 201 is symmetrically provided with roller mounting grooves 207. The rotating roller 203 is rotatably connected to the inner wall of the housing 201 through the roller mounting grooves 207. The side of the housing 201 away from the opening 206 is connected to the adjusting cylinder 204. This device, by setting up a testing auxiliary box 2, allows for auxiliary testing of side-terminal lead-acid batteries 3 when testing is required. The testing auxiliary box 2 is connected to an online high-current testing device via a high-current testing column 1. The testing auxiliary box 2 includes a housing 201 and an L-shaped copper busbar 202. The housing 201 is fitted over the side-terminal lead-acid battery 3, allowing the terminals 4 of the battery 3 to be electrically connected to the high-current testing column 1 via the L-shaped copper busbar 202 for testing. After testing, the housing 201 is disconnected from the battery 3. This process of fitting and disconnecting the housing 201 is repeated, enabling batch testing of side-terminal lead-acid batteries 3 using the same testing auxiliary box 2, improving production efficiency and reducing testing costs. Meanwhile, the testing auxiliary box 2 also includes an adjusting cylinder 204 and a rotating roller 203. When the outer casing 201 is fitted over the side-terminal lead-acid battery 3, the adjusting cylinder 204 is activated, pushing the side-terminal lead-acid battery 3 to move, ensuring that the terminal portion 4 of the side-terminal lead-acid battery 3 is in contact with the L-shaped copper busbar 202. The rotating roller 203 facilitates smoother movement of the side-terminal lead-acid battery 3, improving the reliability of the device.

[0031] Specifically, the width of the first slot 205 and the second slot 208 is greater than that of the L-shaped copper busbar 202, so that the L-shaped copper busbar 202 can move and adjust laterally within the first slot 205 and the second slot 208 to adapt to terminal parts 4 with different spacing specifications.

[0032] Specifically, the connecting hole 209 is set as an oblong hole, which makes it easier for the L-shaped copper busbar 202 to be moved and adjusted laterally.

[0033] Example 2

[0034] See attached document Figure 4-5 The difference between this embodiment and embodiment 1 is that the high current detection column 1 and the L-shaped copper busbar 202 are detachably connected by bolts, which makes it more convenient to disassemble and replace different parts of the device, reduces maintenance costs, and improves maintenance efficiency.

[0035] Specifically, a cylinder connection opening 210 is provided at the connection between the outer casing 201 and the adjusting cylinder 204, and the adjusting cylinder 204 is detachably connected to the cylinder connection opening 210 by bolts. The adjusting cylinder 204 can extend into the outer casing 201 through the connection opening, making the operation of pushing the side-terminal lead-acid battery 3 more reliable and convenient.

[0036] Specifically, the outer casing 201 is configured as a hollow rectangular structure with an open lower end, which allows the outer casing 201 to better adapt to the shape of the side-mounted lead-acid battery 3, thereby making the connection between the outer casing 201 and the side-mounted lead-acid battery 3 more reliable.

[0037] Specifically, several rotating rollers 203 are provided, and the roller mounting grooves 207 are connected one-to-one with the two sides of the several rotating rollers 203. The several rotating rollers 203 are arranged in parallel to each other.
