When the flip module 2 rotates through the rotating shaft 23, it also drives the cover assembly 20 and the floating plate assembly 21 to gradually approach the carrier module 1. Finally, the flip module 2 and the carrier module 1 are limited up and down, so that the floating plate assembly 21 is limited and matched with the product to be tested 10, and the needle assembly 22 also contacts the contact of the product to be tested 10.
[0022] like Figure 2 and Figure 3 As shown, in this embodiment, the cover assembly 20 includes a snap element 200, a pair of bearing limit seats 201, and a rotation limit block 202. The snap element 200 is provided on the side of the cover assembly 20 away from the rotating shaft 23. One side of the rotation limit block 202 is fixed to the cover assembly 20, and the other side of the rotation limit block 202 is rotationally engaged with the rotating shaft 23. The bearing limit seats 201 are respectively provided on both sides of the lower surface of the cover assembly 20. It can be seen that the rotation limit blocks 202 are provided on the cover assembly 20 to prevent the cover assembly 20 from rotating too much during rotation, thereby locking the cover assembly 20. The bearing limit seats 201 are provided to achieve the limited engagement between the cover assembly 20 and the floating plate assembly 21.
[0023] like Figure 2 and Figure 4As shown, in this embodiment, the floating plate assembly 21 includes a floating pressure plate 210 and a floating plate element 211. The floating pressure plate 210 is fixed on the floating plate element 211. The floating plate element 211 is floatingly engaged with the floating pressure plate 210 through the pressure plate contour screw 212 and the first spring 213. A pair of ball bearings 214 are provided on both sides of the floating pressure plate 210, and the ball bearings 214 are limitedly engaged with the bearing limit seat 201. It can be seen that the floating plate assembly 21 is limited and matched with the cover plate assembly 20 through the ball bearing 214, and the pressure plate height screw 212 and the first spring 213 are provided between the floating pressure plate 210 and the floating plate element 211. By utilizing this structure of the pressure plate height screw 212 and the first spring 213, when the floating plate assembly 21 gradually approaches the carrier module 1, the large instantaneous pressure generated during the rotation is absorbed, thereby playing a protective role for the clamping module 3 and the product to be tested 10 on the carrier module 1.
[0024] like Figure 5 and Figure 6 As shown, in this embodiment, the carrier module 1 also includes a plurality of flip-up connecting seats 11, a carrier component 12, a carrier base 13, and a snap limit block 14. The flip-up connecting seat 11 is arranged on the side of the carrier module 1 close to the rotating shaft 23, and the flip-up connecting seat 11 is rotatably matched with the rotating shaft 23. The carrier component 12 is limited and matched on the carrier base 13 by the carrier height screw 15, the second spring 16 and a plurality of carrier guide columns 17. The second spring 16 is arranged between the carrier component 12 and the carrier base 13, and both ends of the second spring 16 are limited and matched with the carrier component 12 and the carrier base 13. The carrier guide column 17 is fixed on the carrier base 13. The snap limit block 14 is arranged on the side of the carrier base 13 away from the rotating shaft 23, and the snap limit block 14 is limited and matched with the snap element 200. It can be seen that the carrier element 12 and the carrier base 13 are also provided with the carrier height screw 15 and the second spring 16, which absorb the large instantaneous pressure generated during rotation through the carrier height screw 15 and the second spring 16, thereby protecting the clamping module 3 and the product to be tested 10 on the carrier module 1. At the same time, when the flip module 2 is rotated to be parallel to the carrier base 13, the buckle limit block 14 is limited and cooperated with the buckle element 200, so that the flip module 2 is stuck. At the same time, the needle assembly 22 contacts the contact point of the product to be tested 10.
[0025] like Figure 6As shown, in this embodiment, the needle assembly 22 is fixed to the carrier base 13, and the needle assembly 22 is limitedly engaged with the lower surface of the product under test 10. As can be seen, when the product under test 10 is squeezed by the flip module 2, the needle assembly 22 will contact the contact point on the lower surface of the product under test 10, thereby transmitting the test signal.
[0026] like Figure 6 As shown, in this embodiment, the carrier base 13 is provided with a plurality of guide sleeves 130 and a plurality of guide holes 131. The guide sleeves 130 are engaged with the external device in a limited position, and the guide holes 131 are engaged with the floating pressure plate 210 in a limited position. Thus, it can be seen that the guide sleeves 130 play a guiding and positioning role when the carrier base 13 is engaged with the external device.
[0027] like Figure 7 As shown, in this embodiment, the clamping module 3 includes a product moving clamping assembly 30, a product side positioning block 31, and a product bottom positioning block 32.

The product side positioning block 31 is limited in position with the rectangular notch on the product to be tested 10, and the product bottom positioning block 32 is limited in position with the bottom surface of the product to be tested 10. It can be seen that the product moving clamping assembly 30 is used to clamp and move the product to be tested 10, move the product to be tested 10 toward the product side positioning block 31, allow the rectangular notch on the product to be tested to be limited in position with the product side positioning block 31, and at the same time, allow the product bottom positioning block 32 to be limited in position with the bottom surface of the product to be tested 10, so that each product to be tested 10 can be accurately positioned and the repeated positioning accuracy is high.
[0028] like Figure 2 and Figure 4 As shown, in this embodiment, the floating pressure plate 210 is provided with a plurality of pressure rods 90, which pass through the floating plate element 211 and are limitedly engaged with the carrier element 12. The floating plate element 211 is provided with a plurality of pressure plate guide posts 91, which are limitedly engaged with the guide holes 131. Thus, it can be seen that the floating pressure plate 210 is provided with the pressure rods 90, and during the rotation of the flip module 2, the pressure rods 90 squeeze the carrier element 12, causing the carrier element 12 to move downward, and the contact points on the lower surface of the product to be tested 10 that are limitedly engaged with the carrier element 12 will contact the needle assembly 22, thereby transmitting the test signal.
[0029] like Figure 8As shown, in this embodiment, the product moving and clamping assembly 30 includes a push block moving seat 300, a push block element 301, a plurality of third springs 302 and a plurality of guide shafts 303, the push block moving seat 300 is arranged on the rectangular notch of the carrier element 12, the push block element 301 is fixed on the push block moving seat 300, the two ends of the guide shaft 303 are limitedly engaged with the push block moving seat 300, the push block element 301 is slidably engaged with the guide shaft 303, the third spring 302 is arranged between the push block moving seat 300 and the push block element 301, and the two ends of the third spring 302 are limitedly engaged with the push block moving seat 300 and the push block element 301. It can be seen that the push block moving seat 300 drives the push block element 301 to move back and forth along the guide shaft 303. Because the product to be tested 10 is limitedly engaged with the product moving clamping assembly 30, it also drives the product to be tested 10 to move back and forth. The third spring 302 is provided between the push block moving seat 300 and the push block element 301, so that when the product to be tested 10 needs to be tested, the operator needs to pull the push block element 301. At the same time, the third spring 302 absorbs the pulling force and converts it into elastic force. When the test is completed, the tested product can be taken out quickly.
[0030] In this embodiment, the working principle of the utility model is as follows:
[0031] like Figures 1 to 8 As shown, the operator pulls open the pushing block element 301, places the product to be tested 10 into the clamping module 3, releases the pushing block element 301, and the product to be tested 10 is moved to the right by the third spring 302 until the product to be tested 10 is limited by the product side positioning block 31 and the product bottom positioning block 32, and then slowly covers the flip module 2. During the rotation of the flip module 2, the pressure plate guide column 91 is driven to limit and cooperate with the guide hole 131, and the floating plate element 211 is fitted with the carrier plate element 12 until the buckle element 200 is limited and cooperates with the buckle limit block 14. At the same time, the floating pressure plate 210 is tightly fitted to the product to be tested 10, and the product to be tested 10 is squeezed and contacts and cooperates with the needle assembly 22. After the test is completed, the buckle element 200 is toggled to open the flip module 2 and take out the completed test product 10, and this cycle is repeated.
[0032] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
