Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to an integrity testing device for a lithium battery cap assembly. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. The lithium battery cap is a key component of the lithium battery. It is located at the positive electrode and is directly connected to the tab. During the production of lithium battery caps, random inspections are carried out on the lithium battery caps. Therefore, it is necessary to use the corresponding integrity testing device.

[0003] However, existing integrity testing devices for lithium battery caps use air pressure to detect holes. This method cannot quickly identify holes with a diameter < φ0.1mm, thus lacking the ability to rapidly perform integrity testing on lithium battery caps and affecting the efficiency of random inspections. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0005] An integrity testing device for a lithium battery assembly cap includes a support plate;

[0006] A Z-shaped detection seat is provided at the upper end of the support plate. A sliding groove is provided on the side of the detection seat away from the support plate. A telescopic cylinder is provided on the side of the detection seat close to the support plate. The telescopic end of the telescopic cylinder faces the sliding groove and is equipped with a slider that slides and engages with the sliding groove. A detection groove is opened at the upper end of the slider. A light-transmitting hole is provided in the middle of the detection groove. The light-transmitting hole penetrates the detection seat downwards. A light source is provided at the lower end of the detection seat away from the support plate corresponding to the light-transmitting hole.

[0007] The end of the detection seat away from the telescopic cylinder has a feed inlet corresponding to the detection groove, and the other end of the detection seat near the telescopic cylinder has a discharge outlet.

[0008] A support column is provided on one side of the support plate, and a fixing plate is slidably provided on the upper part of the support column. The other end of the fixing plate is provided on the upper end of the detection groove and a detection camera is installed thereon. The shooting end of the detection camera is set towards the detection groove.

[0009] The outer side of the detection camera is fitted with a light shield, the lower end of which extends downward to the lower end of the light source.

[0025] Please see Figure 1-3 An integrity testing device for a lithium battery cap includes a support plate 1;

[0026] A Z-shaped detection seat 2 is provided at the upper end of the support plate 1. A sliding groove 3 is provided on the side of the detection seat 2 away from the support plate 1. A telescopic cylinder 4 is provided on the side of the detection seat 2 close to the support plate 1. The telescopic end of the telescopic cylinder 4 faces the sliding groove 3 and is equipped with a slider 5 that slides and cooperates with the sliding groove 3. A detection groove 6 is provided at the upper end of the slider 5. A light-transmitting hole 7 is provided in the middle of the detection groove 6. The light-transmitting hole 7 penetrates the detection seat 2 downward. A light source 8 is provided at the lower end of the detection seat 2 away from the support plate 1, corresponding to the light-transmitting hole 7.

[0027] The end of the detection seat 2 away from the telescopic cylinder 4 is provided with a feed inlet 9 corresponding to the detection groove 6, and the other end of the detection seat 2 near the telescopic cylinder 4 is provided with a discharge outlet 10.

[0028] A support column 11 is provided on one side of the support plate 1, and a fixing plate 12 is slidably provided on the upper part of the support column 11. The other end of the fixing plate 12 is provided on the upper end of the detection groove 6 and a detection camera 13 is installed thereon. The shooting end of the detection camera 13 is set towards the detection groove 6.

[0029] A light-shielding tube 14 is fitted around the outside of the detection camera 13, and the lower end of the light-shielding tube 14 extends downward to the lower end of the light source 8.

[0030] During operation, the lithium battery assembly cap is placed into the detection tank 6 through the feed port 9, blocking the light-transmitting hole 7. The light source shines upward. If the lithium battery assembly cap is intact and has no holes on its surface, it cannot transmit light, and the detection camera 13 cannot capture the light spot. If the detection camera 13 captures the light spot, the lithium battery assembly cap is a defective product. After the detection is completed, the telescopic cylinder 4 drives the slider 5 to retract, causing the lithium battery assembly cap to move outward from the discharge port 10. The light-blocking tube 14 can ensure that the working environment of the detection camera 13 is completely dark, improving the accuracy of the detection.

[0031] A further solution: A light shield 15 is provided on the upper end surface of the detection seat 2 near the telescopic cylinder 4.

[0032] Increase the light-blocking effect of the testing environment to ensure the accuracy of the test.

[0033] A further solution: An air inlet 16 is provided on the opposite side of the detection seat 2 and the discharge port 10, and the air inlet 16 is connected to an external air source.

[0034] After the test is completed, the telescopic cylinder 4 drives the slider 5 to retract, causing the test tank 6 to move to the discharge port 10. An external air source blows air into the test tank 6 through the air inlet 16, blowing the lithium battery assembly cap out from the discharge port 10.

[0035] A further solution: A limit block 17 is provided on the side of the sliding groove 3 near the telescopic cylinder 4. When the slider 5 and the limit block 17 are in contact with each other, the discharge port 10 and the detection groove 6 correspond to each other.

[0036] It can ensure that when the telescopic cylinder 4 drives the slider 5 to retract backward, the detection groove 6 is aligned with the discharge port 10.

[0037] A further solution: A locking sleeve 18 is provided at the upper end of the fixing plate 12 near the support column 11. The locking sleeve 18 is fitted onto the support column 11, and the locking sleeve 18 fixes the fixing plate 12 to the support column 11 through a locking element.

[0038] The detection camera 13 can move up and down on the support column 11 to adjust the detection distance and ensure the accuracy of the detection results. The locking sleeve 18 can fix the detection camera 13 on the support column 11.

[0039] It can also be connected to an external feeding component through the feed port 9 to improve feeding efficiency. The external feeding component is a common existing technology in the field (such as vibratory feeding), so it will not be described in detail.

[0040] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
