[0001] This utility model relates to the field of battery testing, and in particular to battery testing equipment for testing cylindrical batteries. Background Technology

[0002] In modern industrial production, cylindrical batteries are core components widely used in electronic products, electric vehicles, energy storage systems, and other fields. Their performance and quality directly affect the reliability and safety of end products. With the continuous growth in market demand for cylindrical batteries and the diversification of product specifications, the testing of cylindrical batteries is of paramount importance.

[0003] Existing cylindrical battery testing methods typically involve mounting the cylindrical battery onto the testing equipment using a clamp, and then driving the testing equipment to perform the testing. However, current testing methods cannot simultaneously clamp and test the battery, which is time-consuming, increases operational complexity, and affects testing efficiency. Furthermore, current equipment can only test and clamp batteries of specific specifications, making it difficult to quickly adapt to testing cylindrical batteries of different specifications. This results in poor flexibility and inconvenience in use.

[0004] Therefore, it is necessary to design a battery testing device that can automatically clamp and test cylindrical batteries of different specifications, is simple to operate, reduces manual intervention, improves testing efficiency and stability, and is flexible and convenient to use for testing cylindrical batteries. Utility Model Content

[0005] To overcome the shortcomings of current testing methods, such as the inability to simultaneously clamp and test, the time-consuming nature of the process, the increased complexity of operation, the reduced testing efficiency, and the fact that current equipment can only test and clamp batteries of specific specifications, making it difficult to quickly adapt to testing cylindrical batteries of different specifications and resulting in poor flexibility, this invention provides a battery testing device for cylindrical batteries that can automatically clamp and test cylindrical batteries of different specifications simultaneously. This device is simple to operate, reduces manual intervention, improves testing efficiency and stability, and is flexible and convenient to use.

[0006] Technical solution: A battery testing device for testing cylindrical batteries, comprising a support frame, an electric push rod, a pressing block, a guide rod, a clamping assembly, and a testing assembly. The electric push rod is connected to the upper rear front side of the support frame, and the pressing block is connected to the telescopic end of the electric push rod. Guide rods are connected to both the left and right sides of the support frame, and each guide rod is equipped with a clamping assembly for automatically clamping the cylindrical batteries. A testing assembly for testing the cylindrical batteries is located between the support frame and the pressing block.

[0007] In one embodiment, the guide rods are all I-shaped.

[0008] In one embodiment, the clamping assembly includes a rotating frame, a torsion spring, a first roller, a clamping frame, and a first telescopic spring. The rotating frame is rotatably connected to the upper part of each guide rod, and a torsion spring is connected between each rotating frame and the guide rod on the same side. The first roller is rotatably connected to the rear part of each rotating frame, and the first roller is in contact with the extrusion block. The clamping frame is slidably connected to the front part of each rotating frame, and a first telescopic spring is connected between each clamping frame and the rotating frame on the same side.

[0009] In one embodiment, the first rollers are all made of rubber.

[0010] In one embodiment, the sides of the clamps that are close to each other are both arc-shaped.

[0011] In one embodiment, the detection assembly includes a pressing frame, a second roller, a slide rail, a slide cylinder, a second telescopic spring, a detection head, and a third telescopic spring. The pressing block is connected to the pressing frame on both the upper and lower sides. The front of the pressing frame is rotatably connected to two second rollers on the left and right. The upper and lower parts of the support frame are connected to the slide rail. The slide cylinder is slidably connected to the slide rail. The second roller is in contact with the slide cylinder on the same side. The slide cylinder is connected to the slide rail on the same side with a second telescopic spring. The slide cylinder is slidably connected to the detection head. The detection head is connected to the slide cylinder on the same side with a third telescopic spring.

[0012] In one embodiment, the extrusion frames are all L-shaped.

[0013] In one embodiment, the first roller is larger than the second roller.

[0014] The present invention has the following advantages: 1. The present invention uses an electric push rod to drive the extrusion block and extrusion frame to move, thereby moving the first and second rollers, causing the rotating frame to rotate, causing the clamping frame to rotate and move to clamp the cylindrical battery, and causing the detection head to move and then be powered on for detection. Thus, it can automatically clamp cylindrical batteries of different specifications while automatically detecting them. The operation is simple, reduces manual intervention, improves detection efficiency and stability, and is flexible and convenient to use.

[0015] 2. This utility model allows for the handheld operation of a cylindrical battery. The compression block and compression frame then reset the first and second rollers, thereby resetting the rotating frame, clamping frame, slide cylinder, and detection head. The cylindrical battery can then be removed, enabling quick clamping, installation, or removal of the cylindrical battery by hand. This facilitates rapid removal and replacement of the cylindrical battery, promotes one-handed operation, accelerates the testing process, and improves overall testing efficiency.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0023] Battery testing equipment used to test cylindrical batteries, such as Figures 1-5 As shown, the device includes a support frame 1, an electric push rod 2, an extrusion block 3, a guide rod 4, a clamping assembly, and a detection assembly. The electric push rod 2 is connected to the upper rear front side of the support frame 1. The extrusion block 3 is connected to the telescopic end of the electric push rod 2. The guide rods 4 are connected to both the left and right sides of the support frame 1. The guide rods 4 are all I-shaped to facilitate support and guidance. Each guide rod 4 is equipped with a clamping assembly for automatically clamping the cylindrical battery. A detection assembly for detecting the cylindrical battery is provided between the support frame 1 and the extrusion block 3.

[0024] like Figures 1-4As shown, the clamping assembly includes a rotating frame 5, a torsion spring 6, a first roller 7, a clamping frame 8, and a first telescopic spring 9. The rotating frame 5 is rotatably connected to the upper part of each guide rod 4. The torsion spring 6 is connected between each rotating frame 5 and the guide rod 4 on the same side. The first roller 7 is rotatably connected to the rear part of each rotating frame 5. The first roller 7 is in contact with the extrusion block 3. The first roller 7 is made of rubber and has good wear resistance. The clamping frame 8 is slidably connected to the front part of each rotating frame 5. The sides of the clamping frames 8 that are close to each other are arc-shaped to facilitate fitting the shape of the cylindrical battery. The first telescopic spring 9 is connected between each clamping frame 8 and the rotating frame 5 on the same side.

[0025] like Figure 1 , and 2 and Figure 5 As shown, the detection assembly includes an extrusion frame 10, a second roller 11, a slide rail 12, a slide cylinder 13, a second telescopic spring 14, a detection head 15, and a third telescopic spring 16. The extrusion block 3 is connected to the extrusion frame 10 on both the upper and lower sides. The extrusion frame 10 is L-shaped. The front of each extrusion frame 10 is rotatably connected to two second rollers 11 on the left and right sides. The first roller 7 is larger than the second roller 11. The support frame 1 is connected to the slide rail 12 on both the upper and lower sides. The slide cylinder 13 is slidably connected to each slide rail 12. The second roller 11 is in contact with the slide cylinder 13 on the same side. The slide cylinder 13 is connected to the slide rail 12 on the same side by the second telescopic spring 14. The detection head 15 is slidably connected to each slide cylinder 13. The detection head 15 is connected to the slide cylinder 13 on the same side by the third telescopic spring 16.

[0026] When testing cylindrical batteries, this device can be used. The support frame 1 is brought into contact with the ground, and the cylindrical battery is lifted and positioned between the clamping frames 8. Then, the electric push rod 2 is activated, causing the pressing block 3 to move and contact the first roller 7, causing the first roller 7 to rotate. This causes the rotating frame 5 to rotate along the guide rod 4, deforming the torsion spring 6. This causes the clamping frame 8 to rotate and contact the cylindrical battery, moving the clamping frame 8 and compressing the first telescopic spring 9, thereby clamping and fixing the cylindrical battery. All guide rods 4 are I-shaped. To facilitate support and guidance, the clamping frames 8 are all arc-shaped on their closest sides to fit the shape of the cylindrical battery. As the extrusion block 3 moves, it also moves the extrusion frame 10. The extrusion frames 10 are all L-shaped, causing the second roller 11 to move and contact the slide cylinder 13, causing the second roller 11 to rotate. This causes the slide cylinder 13 to move along the slide rail 12, compressing the second telescopic spring 14 and causing the detection head 15 to move and contact the positive and negative terminals of the cylindrical battery. The detection head 15 moves according to the length of the cylindrical battery, and the third telescopic spring 16 is stretched, subsequently causing the detection head 15... Power is applied to detect the voltage and internal resistance of the cylindrical battery. The first roller 7 is larger than the second roller 11, allowing for automatic clamping and detection of cylindrical batteries of different sizes. This simplifies operation, reduces manual intervention, improves detection efficiency and stability, and provides flexibility and convenience. After detection, the detection head 15 is de-energized. The cylindrical battery is then held in hand, and the electric push rod 2 reverses its rotation, causing the compression block 3 and the compression frame 10 to move and reset in the opposite direction. This also causes the first roller 7 and the second roller 11 to move and reset in the opposite direction, respectively, relative to the rotating frame 5 and the slide cylinder 13. Upon disengagement, the torsion spring 6 rotates back to its original position, the rotating frame 5 rotates in the opposite direction to reset, the first telescopic spring 9 rebounds, the clamping frame 8 moves in the opposite direction to reset, the second telescopic spring 14 and the third telescopic spring 16 rebound, and the slide cylinder 13 and the detection head 15 move in the opposite direction to reset, thereby removing the cylindrical battery. Then, the electric push rod 2 is closed, allowing for quick clamping, installation, or removal of the cylindrical battery by hand. This facilitates the rapid removal and replacement of the cylindrical battery, enables one-handed operation, accelerates the testing process, and improves the overall testing efficiency. The above operation is then repeated to clamp and test new batteries until all testing is completed.

[0027] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
