Description

Technical Field

[0001] This utility model relates to the field of new energy battery cap testing technology, and in particular to a high-precision new energy battery cap testing device. Background Technology

[0002] The new energy battery cap testing device is a supporting equipment for rapid testing of new energy battery caps. During the processing and assembly of new energy battery caps, it is necessary to quickly test the core on the battery cap. With the continuous development of technology, people's requirements for new energy battery cap testing devices are also getting higher and higher.

[0003] Existing new energy battery cap testing devices have certain drawbacks. First, the resistance testing of existing cap-type electronic components usually uses traditional round-tipped probes, which are prone to poor contact due to single-point contact, resulting in a misjudgment rate as high as 1%, which is not conducive to user use. In addition, round-tipped probes are expensive, have a short lifespan, and pose certain quality risks, which have a certain adverse impact on the actual use process. Therefore, we propose a high-precision new energy battery cap testing device. Utility Model Content

[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figure 1-4As shown, a high-precision new energy battery cap testing device includes a main body 1. A test seat 5 is positioned at the upper end of the main body 1. Support rods 11 are positioned at the four corners of the upper end of the test seat 5. A test plate 6 is installed in the middle of the upper end of the test seat 5. A top seat 8 is fixed at the top of the support rods 11. A lifting cylinder 10 is installed in the middle of the lower end of the top seat 8. A test disk 9 is installed at the bottom of the lifting cylinder 10. A pointed probe assembly 7 is set at the bottom of the test disk 9. A test groove 13 is set in the middle of the upper end of the test plate 6. The test disk 9 is located directly above the test groove 13. A display 2, a controller 3, and an emergency stop switch 4 are set at the front end of the main body 1. Pointed probes are used instead of round probes. The internal structure is made of high-carbon steel and the surface is plated with nickel. Under pressure, the pointed probes form multiple dispersed contact points, which improves the resistance misjudgment rate, enhances test stability, increases probe life, and reduces test costs.

[0021] Furthermore, positioning cylinders 14 are installed around the test plate 6. A telescopic rod 15 is movably arranged inside the positioning cylinder 14. A positioning curved part 16 is positioned at the end of the telescopic rod 15. A protective pad 12 is positioned on the inner surface of the positioning curved part 16. The positioning curved part 16 is located on the outer ring of the test groove 13.

[0022] Furthermore, an elastic component 18 and a connector 17 are connected between the pointed probe assembly 7 and the test disk 9. A connecting rod 19 is connected to the bottom of the pointed probe assembly 7, and a probe tester 21 is connected to the bottom of the connecting rod 19.

The nickel plating layer has a synergistic effect, which inhibits surface oxidation, improves contact resistance stability by 30%, and has a wear resistance life of 60,000 times. Under pressure, the pointed probe forms multiple dispersed contact points, disperses the current path, and reduces contact resistance fluctuations.

[0026] Working principle: This utility model includes a device body 1, a display 2, a controller 3, an emergency stop switch 4, a test base 5, a test plate 6, a pointed probe assembly 7, a top base 8, a test disc 9, a lifting cylinder 10, a support rod 11, a protective pad 12, a test groove 13, a positioning cylinder 14, a telescopic rod 15, a positioning curved component 16, a connector 17, an elastic component 18, a connecting rod 19, a pointed probe body 20, and a probe tester 21.
