Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a battery testing fixture. Background Technology

[0002] The power battery recycling industry is currently at the beginning of a long-term boom cycle. In the next few years, the power battery recycling market will gradually form a new normal of large-scale retirement. The main methods for processing recycled batteries are material resource classification and recycling after crushing and secondary utilization. For secondary utilization, performance testing of the batteries is necessary. Currently, the batteries recycled in the industry are mainly vehicle power batteries and energy storage batteries, with numerous specifications, models, and significant size differences. This means that during secondary processing at the recycling end, corresponding connection fixtures must be designed for batteries of different sizes, resulting in the need for multiple fixtures of different specifications and high costs. Utility Model Content

[0003] The purpose of this utility model is to provide a battery testing fixture to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a battery testing fixture, comprising: a base, on one side of which a first probe is mounted, and the base having a plurality of positioning slots arranged side by side; a clamp, slidably disposed on the other side of the base, with a quick clamp mounted on the top of the clamp and a second probe mounted on the end of the quick clamp, the quick clamp being used to move the second probe a preset distance; and a positioning post, slidably disposed on the clamp, the sliding direction of the positioning post being perpendicular to the sliding direction of the clamp, the positioning post being able to be embedded in any one of the positioning slots to restrict the sliding of the clamp.

[0005] This technical solution offers at least the following advantages: The battery is placed on a base with one electrode contacting the first probe. Then, by pulling out the positioning post, the clamp is moved to a position where the second probe is near the other side of the battery. The positioning post is then embedded in the corresponding positioning groove and fixed. By operating the quick-clamp, the second probe is moved a preset distance until it contacts the other electrode of the battery. That is, the first and second probes contact the positive and negative terminals of the battery, respectively, allowing for battery testing. Furthermore, the clamp's range of motion is large, making this fixture suitable for batteries with significant size differences, reducing the number of fixtures required and lowering costs. In addition, adjusting the clamp position is simple, facilitating efficient processing of different batteries.

[0006] As a further improvement to the above technical solution, the base is equipped with a limiting rack, on which multiple teeth are arranged side by side, forming a positioning groove between adjacent teeth. This facilitates the setting of the positioning groove. Furthermore, since the limiting rack is manufactured independently of the base, its strength can be increased through material selection, thereby ensuring the ability of the positioning groove sidewall to restrict the positioning post.

[0007] As a further improvement to the above technical solution, a first inclined surface is provided on the side of the positioning groove near the first probe, and a second inclined surface is provided at the bottom of the positioning post. A first elastic element is installed between the positioning post and the clamp, providing elastic force to embed the bottom of the positioning post into the positioning groove, causing the first inclined surface to abut against the second inclined surface. Pushing the clamp towards the first probe allows the positioning post to overcome the elastic force of the first elastic element and disengage from the positioning groove under the guidance of the first and second inclined surfaces, thus enabling the clamp to move. When the second probe reaches the position of the battery electrode, releasing the clamp causes the elastic force of the first elastic element to insert the positioning post into a suitable positioning groove, thus limiting the position of the clamp. Then, a quick clamp is used to bring the second probe against the battery electrode. Therefore, by moving the clamp, the second probe can be quickly moved towards the first probe and positioned appropriately, rapidly adapting to the battery size and further improving battery testing efficiency.

[0008] As a further improvement to the above technical solution, the first elastic element is a helical spring sleeved on the positioning post. The bottom of the clamp is provided with a receiving groove, and the positioning post is provided with a limiting block that can slide in the receiving groove. One end of the helical spring abuts against the bottom wall of the receiving groove, and the other end abuts against the limiting block.

[0009] As a further improvement to the above technical solution, both the first inclined surface and the second inclined surface are curved surfaces.

[0010] As a further improvement to the above technical solution, the top of the positioning column passes through the clamp and is equipped with a lifting handle.

[0011] As a further improvement to the above technical solution, the base is provided with a sliding groove, and a slider that is slidably disposed in the sliding groove is installed at the bottom of the clamp.

[0012] As a further improvement to the above technical solution, a fixed seat is installed on both sides of the base. Each fixed seat has a vertically arranged adjustment groove, and an adjustment screw is slidably mounted in the adjustment groove. A support plate is installed between the two fixed seats, and the support plate is threadedly connected to the adjustment screw. One end of the adjustment screw abuts against the end of the fixed seat away from the support plate. When the battery to be tested is placed on the support plate, the height of the support plate can be adjusted by loosening the adjustment screw, allowing it to slide in the adjustment groove, to accommodate batteries of different thicknesses.

[0013] As a further improvement to the above technical solution, the second probe is provided with a mounting screw that is threadedly connected to the quick clamp. The second probe can be detachably mounted on the quick clamp via the mounting screw, facilitating the removal and replacement of the second probe.

[0014] As a further improvement to the above technical solution, the quick clamp includes a support installed on the clamp seat. One end of the support is provided with a slip ring, and the other end is rotatably mounted with a handle. A connecting rod is rotatably mounted in the middle of the handle, and a push rod is rotatably mounted at the end of the connecting rod away from the handle. The push rod is slidably connected to the slip ring. The second probe is mounted on the push rod. The support is provided with a limiting surface, and the end of the handle is formed with at least two positioning surfaces. When the handle is turned so that different positioning surfaces abut against the limiting surface, the push rod can be placed in different push stroke positions. Attached Figure Description

[0026] Reference Figure 1-5The battery testing fixture includes a base 100, a clamp 300, and a quick clamp 400. A vertical plate is erected on the left side of the base 100, and a first probe 200 is mounted on the plate, with its probe end facing horizontally to the right. Two parallel sliding grooves 130 are respectively formed on the front and rear sides of the right side of the base 100, with the right end of each groove 130 penetrating the right side of the base 100. Slider blocks 320 are provided on both the front and rear sides of the clamp 300. The sliders 320 are adapted to the sliding grooves 130, meaning that the two sliders 320 can slide from the right side of the base 100 into their respective sliding grooves 130, allowing the clamp 300 and the base 100 to slide relative to each other in the left-right direction. The cross-section of the slider 320 in the sliding direction can be dovetail-shaped or T-shaped.

[0027] A groove is formed at the top of the base 100, between the two sliding grooves 130, and a limiting rack 110 is embedded in the groove. Multiple teeth 111 are arranged side-by-side along the left-right direction on the limiting rack 110, and a positioning groove 112 is formed between two adjacent teeth 111; that is, multiple positioning grooves 112 are formed side-by-side on the limiting rack 110. In other embodiments, the positioning grooves 112 can also be directly formed at the corresponding position on the top of the base 100.

[0028] The clamp 300 is provided with a positioning post 600, and a first elastic member 700 is installed between the positioning post 600 and the clamp 300. The first elastic member 700 provides elastic force to insert the bottom of the positioning post 600 into the positioning groove 112. Thus, the positioning groove 112 can be used to restrict the positioning post 600, thereby restricting the sliding of the clamp 300 relative to the base 100 and fixing the position of the clamp 300.

[0029] Specifically, a receiving groove 310 is provided at the bottom of the clamp 300, where the positioning post 600 passes through. The receiving groove 310 is positioned above the limiting rack 110. The positioning post 600 is provided with a limiting block 610, which is adapted to the receiving groove 310, allowing the limiting block 610 to slide up and down within the receiving groove 310. The internal space of the through hole in the clamp 300 through which the positioning post 600 passes is square, and the portion of the positioning post 600 passing through the through hole is also adapted to be square, thus restricting the positioning post 600 to slide up and down relative to the clamp 300 and preventing it from rotating. The first elastic element 700 is a helical spring, which is sleeved on the outside of the positioning post 600, with one end of the helical spring abutting against the top of the limiting block 610 and the other end abutting against the bottom wall of the receiving groove 310. The helical spring is in a compressed state, therefore, the helical spring can provide the elastic force to push the limiting block 610 down, so that the bottom of the positioning post 600 is inserted into the positioning groove 112.

[0030] The left side wall of the positioning groove 112 is provided with a first inclined surface 120, which is an arc surface. The left side of the base of the positioning post 600 is provided with a second inclined surface 630, which is also an arc surface. When the bottom of the positioning post 600 is inserted into the positioning groove 112, under the elastic force of the first elastic element 700, the first inclined surface 120 and the second inclined surface 630 abut against each other, and the right side of the bottom of the positioning post 600 abuts against the right side wall of the positioning groove 112, thereby restricting the position of the positioning post 600 and thus restricting the position of the clamp 300.

[0031] By pushing the clamp 300 to the left, guided by the first inclined surface 120 and the second inclined surface 630, the positioning pin 600 can be pushed out of the positioning groove 112, overcoming the elastic force of the first elastic element 700, so that the clamp 300 can move. After releasing the clamp 300, under the elastic force of the first elastic element 700, the positioning pin 600 can be reinserted into the corresponding positioning groove 112, thereby limiting the position of the clamp 300.

[0032] When it is necessary to move the clamp 300 to the right, the positioning pin 600 is pulled upward to overcome the elastic force of the first elastic element 700 and cause the bottom of the positioning pin 600 to extend out of the positioning groove 112. After the clamp 300 is moved to the desired position, the positioning pin 600 is released. Under the elastic force of the first elastic element 700, the positioning pin 600 is reinserted into the positioning groove 112 at the corresponding position to limit the position of the clamp 300.

[0033] Furthermore, a lifting handle 620 is detachably mounted on the top of the positioning post 600 through the clamp 300 and bolted on. The lifting handle 620 includes a circular plate and an arc strip. The circular plate is detachably connected to the positioning post 600 by bolts, and the arc strip is semi-circular with both ends fixed to the top surface of the circular plate. This allows the positioning post 600 to be pulled by hooking the arc strip. In other embodiments, the lifting handle 620 can also be a complete circular ring or a sphere.

[0034] The quick clamp 400 includes a support 410, a slip ring 420, a handle 430, a connecting rod 440, and a push rod 450. The support 410 is bolted to the clamp 300. The slip ring 420 is fixedly mounted on the left side of the support 410. One end of the handle 430 is rotatably mounted on the right side of the support 410. One end of the connecting rod 440 is rotatably connected to the middle of the handle 430, and the end of the connecting rod 440 away from the handle 430 is rotatably connected to the right end of the push rod 450. The push rod 450 passes through the slip ring 420, meaning that the push rod 450 and the slip ring 420 are slidably connected relative to each other. A second probe 500 is mounted on the left end of the push rod 450, with the detection end of the second probe 500 facing left. By rotating the handle 430, the connecting rod 440 can be driven to push the push rod 450 to slide, thereby pressing the second probe 500 against the electrode of the battery under test.

[0035] The handle 430 near the support 410 has two positioning surfaces 460 at different angles, with a limiting angle between them. The top of the support 410 has a horizontal limiting surface 470. When the handle 430 is rotated, the limiting angle abuts against the limiting surface 470, causing the positioning surface 460 corresponding to the rotation direction to abut against the limiting surface 470. This gives the handle 430 two stable angular positions, meaning the push rod 450 has two stable push positions. By shifting the handle 430 back and forth between the two states where the two positioning surfaces abut against the limiting surface 470, the push rod 450 can be pushed to two different push positions, allowing it to move a preset distance. When the clamp 300 quickly moves to a position where the second probe 500 is close to the battery electrode, shifting the handle 430 again causes the push rod 450 to push the second probe 500 against the battery electrode, maintaining a stable contact state, thus enabling battery testing.

[0036] The housing of the second probe 500 is fitted with a mounting screw 510, which is threaded to the left end of the push rod 450, thus allowing the second probe 500 to be detachably connected to the push rod 450 for easy disassembly, assembly, maintenance, and replacement. One of the first probe 200 and the second probe 500 is a positive probe, and the other is a negative probe. For example, the first probe 200 may be a positive probe, and the second probe 500 a negative probe. Both the first probe 200 and the second probe 500 are high-current elastic contact probes.

[0037] Furthermore, fixing seats 800 are bolted to both the front and rear sides of the base 100, and a support plate 830 is installed between the two fixing seats 800. Two adjusting screws 820 are threaded through both the front and rear sides of the support plate 830. Adjusting slots 810 are respectively formed on the fixing seats 800 corresponding to the positions of the two adjusting screws 820 on the same side, allowing the adjusting screws 820 to slide up and down. One end of the adjusting screw 820 is threadedly connected to the support plate 830, the middle of the adjusting screw 820 slides in the corresponding adjusting slot 810, and the end of the adjusting screw 820 away from the support plate 830 abuts against the side of the fixing seat 800 away from the support plate 830, so that the adjusting screw 820 and the support plate 830 clamp the fixing seat 800 to stabilize the height position of the support plate 830. The adjusting screws 820 can be wing bolts.

[0038] Depending on the battery thickness, the adjusting screw 820 can be loosened to adjust the support plate 830 to the required height, and then the adjusting screw 820 can be tightened so that when the battery under test is placed on the support plate 830, the heights of the electrodes on both sides of the battery under test correspond to the heights of the first probe 200 and the second probe 500, respectively. Therefore, the fixture in this embodiment can be adapted to batteries of different thicknesses.

[0039] The steps for using the tooling in this embodiment are as follows:

[0040] Step 1: Place the square battery to be tested on the carrier plate 830, so that one end of the battery is close to the first probe 200.

[0041] Step 2: By pushing the clamp 300, slide the clamp 300 to a suitable position (if the distance between the second probe 500 and the first probe 200 is less than or equal to the length of the battery to be tested, before putting the battery in, pull up the positioning post 600 and slide the clamp 300 to a suitable position according to the length of the battery to ensure that the battery can be placed smoothly on the support plate 830).

[0042] Step 3: Adjust the support plate 830 under the battery to a suitable height using the adjusting screw 820, according to the thickness of the battery;

[0043] Step 4: Push the handle 430 of the quick clamp 400 to bring the positive and negative terminals of the battery into contact with the first probe 200 and the second probe 500, respectively.

[0044] Step 5: Start the testing equipment and begin battery charging and discharging tests.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
