Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lithium battery testing technology, and specifically relates to a lithium battery bulging detection device. Background Technology
[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage and use of lithium metal require very high environmental standards.
[0003] Lithium batteries can bulge during the production process, so they need to be tested before being put on the market to remove any batteries that show signs of bulging.
[0004] Currently, Chinese utility model patent CN217857398U discloses a lithium battery bulging detection device, which relates to the field of lithium battery detection technology. During the detection process, the lithium battery is manually moved for detection, which has low detection efficiency. At the same time, when the lithium battery to be tested slides across the upper surface of the moving plate, it is limited by the limiting plate. It can only detect lithium batteries of fixed size, which limits its use. Utility Model Content
[0005] The purpose of this invention is to provide a lithium battery bulging detection device, which has the advantages of facilitating the transport of lithium batteries and enabling the detection of lithium batteries of different sizes.

[0007] The above technical solution involves using a conveyor to transport lithium batteries to the testing rack for inspection. When a bulge is detected in the lithium battery, an electric push rod is activated to move the top plate, pushing the lithium battery off the conveyor belt. The pushed-out lithium battery enters the collection plate through a groove for easy retrieval. Pulling the pull block disengages the limiting rod from the limiting hole, thereby releasing the restriction on the connecting column. At this time, the first spring is in a stretched state. Then, the connecting column is moved to move the testing wheel closer to or away from the conveyor belt, thus facilitating the inspection of lithium batteries of different sizes.
[0008] The present invention is further configured such that: the conveyor includes a motor, a connecting shaft, a conveyor belt and a collecting mechanism; a motor is provided on one side of the conveyor; the output end of the motor is fixedly connected to the connecting shaft; and a conveyor belt is provided on the outer side of the connecting shaft.

[0017] The above technical solution facilitates the fixing of the connecting column.
[0018] The present invention is further configured such that the detection plate includes a connecting rod, a connecting block, a second spring, an alarm, and a positioning rod. The connecting rod is fixedly connected to the top of the detection plate, and the connecting block is fixedly connected to the top of the connecting rod.

[0024] 2. Pull the pull block to disengage the limit rod from the limit hole, thereby releasing the restriction on the connecting column. At this time, the first spring is in a stretched state. Then, move the connecting column to drive the detection wheel to move closer to or away from the conveyor belt, which facilitates the detection of lithium batteries of different sizes.

[0031] refer to Figure 1A lithium battery bulging detection device includes a conveyor 1 with a detection frame 2 fixedly connected to the top of the conveyor 1. The conveyor 1 includes a motor 101, a connecting shaft 102, a conveyor belt 103 and a collection mechanism. The motor 101 is provided on one side of the conveyor 1, and the output end of the motor 101 is fixedly connected to the connecting shaft 102. The conveyor belt 103 is provided on the outside of the connecting shaft 102.

A groove 10 is opened on the top of the conveyor 1, and a collection plate 11 is fixedly connected to one side of the groove 10.
[0034] Brief description of the usage process: Place the lithium battery on the conveyor belt 103, start the motor 101 to make the connecting shaft 102 drive the conveyor belt 103 to rotate, so that the lithium battery can be moved to the bottom of the detection frame 2 for detection. When the lithium battery bulge is detected, start the electric push rod 8 to drive the top plate 9 to move and push the lithium battery off the conveyor belt 103. The pushed-out lithium battery enters the collection plate 11 through the groove 10 for easy handling by personnel.
[0035] Example 2:
[0036] refer to Figure 1 , Figure 2 and Figure 3 A lithium battery bulging detection device includes a conveyor 1, a detection frame 2 fixedly connected to the top of the conveyor 1, a detection wheel 3 arranged above the conveyor 1, a connecting column 4 arranged on the top of the detection wheel 3, a support column 5 slidably connected to the outside of the connecting column 4, a detection plate 6 fixedly connected to the top of the support column 5, and a slider 7 fixedly connected to the outside of the connecting column 4, with the outside of the slider 7 slidably connected to the inner wall of the support column 5.
[0037] refer to Figure 3 The connecting column 4 includes a limiting hole 401, a limiting rod 402, a fixing block 403 and a first spring 404. The inner wall of the connecting column 4 is provided with a limiting hole 401. There are several limiting holes 401, and the several limiting holes 401 are equidistantly arranged.
[0038] refer to Figure 3 The inner wall of the limiting hole 401 is fitted with a limiting rod 402. One end of the limiting rod 402 passes through one side of the support column 5 and is fixedly connected to a fixing block 403.

One end of the first spring 404 is fixedly connected to one side of the fixing block 403, and the other end of the first spring 404 is fixedly connected to one side of the support column 5.
[0039] Pulling the fixing block 403 causes the limiting rod 402 to disengage from the limiting hole 401, thereby releasing the restriction on the connecting column 4. At this time, the first spring 404 is in a stretched state. Then, the connecting column 4 is moved to drive the detection wheel 3 to approach or move away from the conveyor belt 103, which facilitates the detection of lithium batteries of different sizes.
[0040] refer to Figure 2 The detection plate 6 includes a connecting rod 601, a connecting block 602, a second spring 603, an alarm 604, and a positioning rod 605.

[0042] When a lithium battery with a bulge passes the detection wheel 3, the detection wheel 3 will drive the connecting column 4 to move upward, which will cause the support column 5 to drive the detection plate 6 to move upward. When the detection plate 6 moves upward, the connecting rod 601 will drive the connecting block 602 to move upward, which will compress the second spring 603. The connecting block 602 moves upward and touches the alarm 604 to make it sound an alarm, which can alert the staff.
