Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically a positioning device for battery testing. Background Technology

[0002] A battery testing positioning device is an auxiliary device used to accurately and stably fix and position battery samples during battery testing. By fixing the position of the battery, it ensures the stability of the battery testing process, thereby guaranteeing the accuracy, repeatability, and safety of battery testing data.

[0003] A positioning device for lithium battery testing disclosed in Chinese Patent Publication No. CN209280001U can directly and conveniently position lithium batteries and facilitate unloading after testing. By rotating the handle counterclockwise, the turntable rotates, which drives the threaded rod to rotate counterclockwise. The threaded rod generates thread force with the threaded hole, so the threaded rod can push the moving plate towards the lithium battery mounting platform. The moving plate pushes the pressure rod, at which point the spring is compressed, and the pressure rod gradually pushes the arc-shaped clamping plate closer to the lithium battery placement slot until the arc-shaped push plate and the lithium battery placement slot form a cylinder. At this point, the handle is stopped, and the lithium battery is fed into the lithium battery placement slot from above, thus completing the positioning. However, the positioning device has low flexibility and certain limitations. It is not convenient for quickly clamping and limiting batteries of different specifications, thus affecting the stability and convenience of testing different batteries, and also affecting the overall applicability of the positioning device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a positioning device for battery testing, including a workbench 1, a testing seat 2 is provided at the center of the upper surface of the workbench 1, a through groove 201 is provided at the center of the upper surface of the testing seat 2, and a placement platform 4 is slidably connected to the top of the through groove 201. It also includes a rotating mechanism 3 and a clamping mechanism 5. The rotating mechanism 3 is used to rotate the testing seat 2 as a whole, and the clamping mechanism 5 is used to stably limit the battery at the top of the placement platform 4. Batteries of different specifications can be placed through the placement platform 4.

[0020] Assembly plates 101 are fixed to the bottom of the left and right sides of the workbench 1. The front and rear ends of the assembly plates 101 are provided with screw grooves. Pull blocks are fixed to the left and right sides of the upper surface of the test seat 2. The assembly plates 101 can facilitate the positioning device to be fixed to the external platform. At the same time, the pull blocks on the test seat 2 can be used to lift the test seat 2.

[0021] The rotating mechanism 3 includes positioning holes 102 evenly spaced around the inside of the worktable 1. A limiting groove 103 is provided at the center of the bottom of the worktable 1. Slots 202 are fixedly connected to the left and right sides of the lower surface of the detection seat 2. A wire 203 rotating in the limiting groove 103 is fixedly connected to the center of the lower surface of the detection seat 2. When the detection seat 2 is lifted, the detection seat 2 can drive the slots 202 to be pulled out from the positioning holes 102 on the worktable 1. At this time, the detection seat 2 can be rotated quickly and rotated to a suitable position. When the detection seat 2 is put down, the slots 202 at the bottom of the detection seat 2 can be inserted into the positioning holes 102 at different positions on the worktable 1, thus fixing the position of the detection seat 2 after rotation.

[0022] The two slots 202 are engaged with two sets of opposing positioning holes 102 on the worktable 1.

[0023] The clamping mechanism 5 includes slots 202 on the left and right sides of the bottom of the through groove 201. A wire 203 is fixed to the outside of the slot 202, and a conductive sheet 204 is fixed to the side of the wire 203 away from the slot 202. A battery 401 is fixed to the center of the bottom of the placement platform 4. Conductive rods 402 are fixed to the left and right sides of the lower surface of the battery 401. A first spring 403 is fixed to the left and right sides of the lower surface of the placement platform 4, and the lower surface of the first spring 403 is fixed to the through groove 201. Movable grooves 501 are opened on the left and right sides of the top of the detection seat 2. A limit slider 502 is slidably connected inside the movable groove 501. A connecting rod 503 is fixed to the inner side of the limit slider 502, and a clamping block 504 is fixed to the inner side of the connecting rod 503. A rubber bag 6 is provided on the outside of the movable groove 501, filled with electrorheological fluid. A second spring 601 is fixed to the center of the rubber bag 6. Under normal conditions, the placement platform 4 is stationary. The battery remains at the top of the slot 201. At this time, the placement platform 4 can push the connecting rod 503 and the limiting slider 502 through the clamping block 504. At the same time, the limiting slider 502 can squeeze the second spring 601 inside the rubber bag 6. When the battery is placed at the top of the placement platform 4, the placement platform 4 moves downward to squeeze the first spring 403. At the same time, due to the reaction force of the second spring 601 being squeezed, the clamping block 504 can be pushed through the limiting slider 502 and the connecting rod 503. At this time, the clamping block 504 can complete the clamping and limiting of the battery on the left and right sides. At the same time, the placement platform 4 pushes the conductive rod 402 at the bottom of the battery 401 into the slot 202. Then the conductive rod 402 can conduct electricity to the rubber bag 6 through the wire 203 and the conductive sheet 204. Then the electrorheological fluid inside the rubber bag 6 is energized and solidified, which can complete the position fixation of the limiting slider 502, the connecting rod 503, and the clamping block 504, and make the clamping block 504 stably clamp the battery on the placement platform 4.

[0024] The conductive rod 402 and the slot 202 are positioned to correspond to each other. The elastic force of the first spring 403 is greater than that of the second spring 601. The inner side of the lower surface of the clamping block 504 is in contact with the inclined surface of the placement platform 4. The upper surface of the conductive sheet 204 is in contact with the rubber bag 6. The rubber bag 6 is made of conductive silicone. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] In this embodiment, the battery to be tested is placed at the center of the top of the placement platform 4. The placement platform 4 is then subjected to force that compresses the first spring 403 below, causing the entire platform 4 to move downwards. Simultaneously, the placement platform 4 releases its restriction on the clamping block 504. Due to the reaction force of the compressed second spring 601, the clamping block 504 is pushed by the limiting slider 502 and connecting rod 503 to clamp the battery on both sides. As the placement platform 4 moves downwards, the conductive rod 402 at the bottom of the placement platform 4 can be inserted into the slot 202 on the detection seat 2, and the conductive rod 402 contacts the wire 203. The battery 401 can then energize the rubber bag 6 through the conductive piece 204 at the top of the wire 203. This energizes and solidifies the electrorheological fluid inside the rubber bag 6, thus fixing the positions of the limiting slider 502, connecting rod 503, and clamping block 504, and ensuring that the clamping block 504 stably clamps the battery. When the detection seat 2 is lifted, the detection seat 2 can drive the slot 202 to be pulled out from the positioning hole 102 on the worktable 1. At this time, the detection seat 2 can be rotated quickly and rotated to a suitable position. When the detection seat 2 is put down, the slot 202 at the bottom of the detection seat 2 can be inserted into the positioning hole 102 at different positions on the worktable 1. After the rotation of the detection seat 2 is completed, the position is fixed and the detection angle is adjusted. When the tested battery is pulled out from the top of the placement platform 4, the reaction force of the first spring 403 being squeezed can push the placement platform 4 to move upward. At the same time, the conductive rod 402 at the bottom of the placement platform 4 can be disconnected from the wire 203, and the current in the rubber bag 6 becomes liquefied. At this time, the upward movement of the placement platform 4 can squeeze the clamping blocks 504 on both sides, and the clamping blocks 504 squeeze the second spring 601 through the limit slider 502. At the same time, the placement platform 4 and the clamping blocks 504 on both sides can be quickly reset.
