Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery processing equipment, and in particular to a rapid testing device for cylindrical lithium batteries. Background Technology
[0002] Cylindrical lithium batteries are a common type of lithium battery, frequently used in various portable small electronic devices. After processing, cylindrical lithium batteries require routine testing to ensure they meet output voltage / current standards. Due to the unique shape of cylindrical lithium batteries, testing them is challenging. The testing equipment must clamp the battery ends to prevent rolling while simultaneously ensuring the two electrodes used for testing are in contact with the battery ends. This places high demands on the structure of the testing equipment, as conventional clamping devices are insufficient. Currently, the conventional method involves setting up multiple testing slots, with cylindrical lithium batteries being manually placed into and removed one by one. This method is not only inefficient but also relies heavily on manual labor, resulting in high testing costs. Utility Model Content
[0003] The purpose of this invention is to provide a rapid testing device for cylindrical lithium batteries, specifically a device suitable for automatically and rapidly testing cylindrical lithium batteries.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rapid testing device for a cylindrical lithium battery, comprising a lithium battery conveying mechanism and fixed plates disposed on both sides of the lithium battery conveying mechanism. Each fixed plate on both sides of the lithium battery conveying mechanism is provided with a transverse slot through hole. A lithium battery testing mechanism is disposed on the outer side of the fixed plates on both sides of the lithium battery conveying mechanism, and the lithium battery testing mechanism is aligned with the transverse slot through hole on the fixed plate.
[0005] Specifically, the fixed plate includes a first inclined guide portion and a straight limiting portion, and the transverse slot through hole is provided on the straight limiting portion; the first inclined guide portion is provided in the upward direction of the straight limiting portion and is inclined inward along the downward direction.
[0006] Specifically, the straight-line limiting part of the fixed plate is provided with a second inclined guide part in the downward direction, and the second inclined guide part is inclined outward in the downward direction.
[0007] Specifically, a limit cover is provided on the top surface of the second inclined guide section.
[0008] Specifically, the lithium battery conveying mechanism consists of several conveying rollers, all of which are driven and connected by a chain drive mechanism.
[0009] The beneficial effects of this utility model are as follows: by setting fixed plates on both sides of the lithium battery conveying mechanism, the fixed plates limit and fix the two ends of the lithium battery. At the same time, a horizontal slot through hole is set on the fixed plate, so that the detection electrode of the detection mechanism used to detect the lithium battery can pass through the horizontal slot through hole and contact the two poles of the lithium battery, thereby realizing automatic and rapid detection of cylindrical lithium batteries, improving detection efficiency and reducing detection costs. Attached Figure Description
[0010] Appendix Figure 1 This is a top view schematic diagram of the overall structure of the cylindrical lithium battery rapid testing device in the embodiment;
[0011] Appendix Figure 2 This is a side view of the lithium battery transfer mechanism and fixing plate of the cylindrical lithium battery rapid detection device in the embodiment. Detailed Implementation
[0012] Example 1, referring to Figure 1-2 A rapid testing device for cylindrical lithium batteries includes a lithium battery conveying mechanism 1 and fixed plates 2 disposed on both sides of the lithium battery conveying mechanism 1. The fixed plates 2 on both sides of the lithium battery conveying mechanism 1 are provided with transverse slot through holes 3. A lithium battery testing mechanism 4 is disposed on the outer side of the fixed plates 2 on both sides of the lithium battery conveying mechanism 1, and the lithium battery testing mechanism 4 is aligned with the transverse slot through holes 3 on the fixed plates 2.
[0013] In this embodiment, the lithium battery conveying mechanism 1 is used to transport the cylindrical lithium battery 10 forward. After the cylindrical lithium battery 10 moves forward to the position of the fixed plate 2, it is limited by the fixed plates 2 on both sides of the lithium battery conveying mechanism 1 to prevent the cylindrical lithium battery 10 from moving laterally. The fixed plates 2 only restrict the lateral movement of the cylindrical lithium battery 10 and do not apply pressure to it. Therefore, the cylindrical lithium battery 10 continues to move forward under the drive of the lithium battery conveying mechanism 1. When the cylindrical lithium battery 10 reaches the detection position of the lithium battery detection mechanism 4, the lithium battery conveying mechanism 1 stops. The two detection electrodes of the lithium battery detection mechanism 4 move forward and contact the two poles of the cylindrical lithium battery 10 through the transverse slot through hole 3 on the fixed plate 2 to realize the detection of the lithium battery. After the detection is completed, the two detection electrodes of the lithium battery detection mechanism 4 retract, and the lithium battery conveying mechanism 1 continues to drive the next lithium battery to the detection position of the lithium battery detection mechanism 4 for detection. The two detection electrodes of the lithium battery detection mechanism 4 need to be able to move back and forth. Specifically, a common linear drive mechanism can be used to detect the two detection electrodes of the lithium battery detection mechanism 4. For example, a small electric screw or a small drive cylinder can be used to drive the two detection electrodes of the lithium battery detection mechanism. It should be noted that the fixing plate 2 can be fixedly installed on both sides of the lithium battery conveying mechanism 1 through the frame without contacting the lithium battery conveying mechanism 1. The installation structure of the frame and the fixing plate 2 is not shown in the attached drawings. The lithium battery detection mechanism 4 can also be fixedly installed on the frame, and its connection structure is also not shown in the attached drawings. The above-mentioned installation and connection structures are all conventional settings in this field and will not be described in detail here.
[0014] The lithium battery conveying mechanism 1 consists of several conveying rollers 11, all of which are driven and connected by a chain drive mechanism. Due to the tendency of the cylindrical lithium battery 10 to roll easily, the lithium battery conveying mechanism 1 is composed of several conveying rollers 11. By using multiple conveying rollers 11 to form a conveying mechanism, the recesses between the rollers 11 can limit the movement of the cylindrical lithium battery 10, preventing it from rotating freely on the lithium battery conveying mechanism 1 and improving the conveying efficiency of the cylindrical lithium battery 10.
[0015] In a further preferred embodiment, the fixing plate 2 includes a first inclined guide portion 21 and a straight limiting portion 22, with the transverse slot through hole 3 disposed on the straight limiting portion 22. The first inclined guide portion 21 is disposed in the upward direction of the straight limiting portion 22 and inclined inward in the downward direction. The first inclined guide portion 21 of the fixing plate 2 can limit and guide the cylindrical lithium battery 10 in advance, allowing the cylindrical lithium battery 10 to gradually enter the space between the straight limiting portions 22. When the cylindrical lithium battery 10 reaches the space between the straight limiting portions 22, the lithium battery detection mechanism 4 can detect the cylindrical lithium battery 10 through the transverse slot through hole 3.
[0016] Furthermore, a second inclined guide portion 23 is provided in the downward direction of the straight-moving limiting portion 22 of the fixed plate 2. The second inclined guide portion 23 is inclined outward in the downward direction; a limiting cover plate 24 is provided on the top surface of the second inclined guide portion 23. The second inclined guide portion 23, provided in the downward direction of the straight-moving limiting portion 22, can continue to limit the cylindrical lithium battery 10 after it has been detected and exited from the straight-moving limiting portion 22. This prevents the cylindrical lithium battery 10 from suddenly exiting from the narrower middle of the straight-moving limiting portion 22 and bouncing due to being stuck by the edge of the straight-moving limiting portion 22. At the same time, the limiting cover plate 24 provided on the top surface of the second inclined guide portion 23 can work in conjunction with the second inclined guide portion 23 to further limit the cylindrical lithium battery 10.
[0017] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
