Detailed implementation manners
[0024] The following further elaborates on the present application in conjunction with the attached Figures 1 - 3 drawings.
[0025] An embodiment of the present application discloses a test module. Referring to Figure 1 and Figure 2 , it includes a mounting frame 1, a test seat 2 mounted on the mounting frame 1 and used for placing products, a pressing head assembly 3 for detecting the products on the test seat 2, and a driving member 4 mounted on the mounting frame 1. The driving member 4 is used to drive the pressing head assembly 3 to move towards the test seat 2. A positioning seat 5 for positioning the pressing head assembly 3 is mounted on the mounting frame 1. A temperature control component 6 located above the pressing head assembly 3 is mounted on the bottom surface of the positioning seat 5. The temperature control component 6 is used to adjust the test temperature of the products. An elastic member 8 for providing test pressure is mounted on the positioning seat 5. In order to facilitate the adjustment of the test pressure, an adjusting member 7 for adjusting the test pressure of the pressing head assembly 3 is mounted on the positioning seat 5. One end of the elastic member 8 is connected to the adjusting member 7, and the other end of the elastic member 8 is connected to the pressing head assembly 3. The adjusting member 7 adjusts the compression force of the elastic member 8 according to the test requirements, improving the adaptability of the test module.
[0026] Referring to Figure 2 and Figure 3 , the adjusting member 7 includes an adjusting nut 71 and an adjusting screw 72. The adjusting nut 71 and the adjusting screw 72 cooperate, and the pressure of the elastic member 8 on the pressing head assembly 3 is adjusted by turning the adjusting screw 72 to tighten. A positioning hole 9 is provided on the top surface of the positioning seat 5, and the positioning hole 9 is used to position the adjusting nut 71; a mounting hole 10 communicating with the positioning hole 9 is provided on the positioning seat 5, and the elastic member 8 is located in the mounting hole 10. In order to facilitate the elastic member 8 to control the pressing head assembly 3, a through hole one 11 communicating with the mounting hole 10 is also provided on the temperature control component 6.
[0027] Referring to Figure 2 and Figure 3, in order to improve the control effect of the adjusting member 7 on the elastic member 8, a control block 12 is installed at one end of the elastic member 8 close to the adjusting screw 72. The control block 12 is located in the first through hole 11. The control block 12 facilitates the adjusting screw 72 to control the elastic member 8 to be compressed. At one end of the elastic member 8 close to the indenter assembly 3, a pressing column 13 is installed. The pressing column 13 equalizes the elastic force exerted by the elastic member 8 on the indenter assembly 3. The elastic member 8 is a rectangular spring. In actual use, the elastic member 8 can use other structures with telescopic and reset capabilities according to needs.
[0028] Referring to Figure 2 and Figure 3 , in order to improve the moving stability of the pressing column 13, the cross section of the pressing column 13 is T-shaped, and the cross section of the first through hole 11 is T-shaped. When the pressing column 13 moves to the lowest end, the convex part of the pressing column 13 is used for positioning to prevent the pressing column 13 from moving out of the first through hole 11 and improve the moving stability of the pressing column 13.
[0029] Referring to Figure 2 and Figure 3 , the indenter assembly 3 includes a fixed seat 31 installed on the bottom surface of the temperature control assembly 6 and a number of test indenters 32 arranged in sequence along the length direction of the fixed seat 31. In the embodiment of the present application, the number of the adjusting members 7 and the elastic members 8 is set according to the number of the test indenters 32. A set of adjusting members 7 and elastic members 8 are adapted to a set of test indenters 32. A second through hole 14 communicating with the first through hole 11 is formed on the fixed seat 31. The second through hole 14 is used to install the test indenter 32. At the same time, the second through hole 14 facilitates the pressing column 13 to control the test pressure of the test indenter 32. In order to improve the moving stability of the test indenter 32, the cross section of the test indenter 32 is T-shaped, and the cross section of the second through hole 14 is T-shaped. When the convex part of the test indenter 32 moves to the bottom end of the second through hole 14, the test indenter 32 is positioned, effectively preventing the test indenter 32 from detaching from the second through hole 14.
[0030] The implementation principle of a test module in the embodiment of the present application is as follows: when it is necessary to adjust the test pressure of the test indenter 32, rotate the adjusting screw 72. The downward movement of the adjusting screw 72 drives the control block 12 to move downward to compress the elastic member 8. The test pressure of the test indenter 32 is controlled by the telescopic movement of the elastic member 8. The pressing column 13 effectively improves the control effect of the elastic member 8 on the test indenter 32 and equalizes the pressing force of the elastic member 8 on the test indenter 32. The present application effectively improves the practicability of the test module, can quickly adjust the test pressure, and reduces the test cost.
[0031] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
