The left and right ends of the first return spring 375 are fixedly connected to the left link rod 372 and the right link rod 373 respectively. The first return spring 375 is provided with two groups and corresponds to the front and rear sides of the left link rod 372 respectively. The left connecting block 376 is fixed to the left end of the left link rod 372, and the right connecting block 377 is fixed to the right end of the right link rod 373.

[0032] When clamping the mobile phone, first, the clamping drive assembly 33 drives the linkage plate 34 to move backward. During the backward movement of the linkage plate 34, in the X-axis direction, the guide groove 341 drives the first roller 374 to move outward, so that the left linkage rod 372 and the right linkage rod 373 move outward along the slide 371, and then drive the left connecting block 376 and the right connecting block 377 to open. In the Y-axis direction, the linkage plate 34 directly drives the clamping block connecting assembly 381 to move backward, so that the rear clamping block 383 moves backward, and the Z-axis clamping assembly 39 also moves with the left connecting block 376 and The right connecting block 377 is opened, at this time, the operator places the mobile phone on the top carrier plate 36, then, the clamping drive assembly is reset, and at the same time, under the action of the first reset spring 375, the left connecting block 376 and the right connecting block 377 are reset inward, so that the right clamping block 379 moves to the left and clamps the mobile phone to the left clamping block 378, and the rear clamping block 383 moves forward and clamps the mobile phone to the forward clamping block 382, ​​finally, the Z-axis clamping assembly 39 presses the mobile phone downward on the top carrier plate 36, thus completing the clamping of the mobile phone, which is not only efficient but also has high clamping accuracy.

[0033] The frame 32 is provided with a first guide rod 321 and a second return spring 322. The first guide rod 321 passes through the linkage plate 34.

[0034] The clamping drive assembly 33 includes a cylinder fixing plate 331 and a driving cylinder 332. The cylinder fixing plate 331 is provided with a first strip hole 3311 on the left and right sides. The cylinder fixing plate 331 is fixed on the top of the mounting base plate 31 by screws passing through the first strip hole 3311. The driving cylinder 332 is fixed on the cylinder fixing plate 331. The linkage plate 34 is fixed on the power output end of the driving cylinder 332. The position of the cylinder fixing plate 331 on the mounting base plate 31 can be adjusted through the first strip hole 3311, thereby fine-tuning the position of the driving cylinder 332 to improve the accuracy.

[0035] The clamping block connecting assembly 381 includes a front connecting rod 3811, a rear connecting rod 3812, a guide sleeve 3813, a second guide rod 3814 and a third return spring 3815. The guide sleeve 3813 is fixed to the front end of the rear connecting rod 3812. The front end of the second guide rod 3814 is fixed to the front connecting rod 3811, and the rear end is passed through the guide sleeve 3813. The rear end of the second guide rod 3814 can slide in the guide sleeve 3813. The front connecting rod 3811 is fixed to the linkage plate 34. The two ends of the third return spring 3815 are respectively fixed to the front connecting rod 3811 and the rear connecting rod 3812. The rear clamping block 383 is fixed above the rear connecting rod 3812.

[0036] When the clamping drive assembly 33 drives the clamping block connecting assembly 381 to move forward, the linkage plate 34 drives the front connecting rod 3811 to move, and the front connecting rod 3811 drives the rear connecting rod 3812 to move forward through the third return spring 3815. When the rear clamping block 383 contacts the side of the mobile phone, the front connecting rod 3811 and the second guide rod 3814 move forward relative to the rear connecting rod 3812 and the guide sleeve 3813, and the third return spring 3815 is stretched, so that the front clamping block 382 and the rear clamping block 383 clamp the mobile phone.

[0037] The Z-axis clamping assembly 39 includes a lifting base plate 391, a lifting top rod 392, a third guide rod 393, a second roller 394 and a pressing plate 395.

The lifting base plate 391 is provided with second strip holes 3911 on both sides of the left and right sides. The upper end of the lifting top rod 392 is fixed on the lifting base plate 391, and the lower end passes through the mounting base plate 31 and the turntable. The third guide rod 393 is arranged on the left and right sides of the lifting base plate 391. The third guide rods 393 on the left and right sides are respectively vertically passed through the left connecting block 376 and the right connecting block 377. The second roller 394 can be rotatably installed at the lower end of the third guide rod 393. The second roller 394 corresponds to the second strip hole 3911 and can slide left and right in the second strip hole 3911. The pressing plate 395 is provided with a group on each side and is respectively fixed to the upper ends of the third guide rods 393 on the left and right sides.

[0038] Before the clamping drive assembly 33 drives the X-axis clamping assembly 37 to open, the lifting push rod 392 is first driven upward by the lifting mechanism 4, thereby driving the lifting base plate 391 and the pressure plate 395 to move upward. When the left connecting block 376 and the right connecting block 377 are opened outward, the third guide rod 393 also moves outward, so that the second roller 394 moves outward along the second strip hole 3911, and then the pressure plate 395 is also opened outward. After the mobile phone is placed on the top carrier plate 36, the left connecting block 376 and the right connecting block 377 move inward so that the left clamping block 378 and the right clamping block 379 clamp the mobile phone, and the pressure plate 395 corresponds to the left and right sides above the mobile phone. At this time, the lifting mechanism 4 is reset, and under the action of gravity, the lifting base plate 391 moves downward, so that the pressure plate 395 presses the mobile phone downward.

The laser measuring instrument 645 is installed on the angle adjustment assembly 644 and the angle can be adjusted.

[0040] When performing step detection on the side buttons of the mobile phone, the mobile phone is placed on the clamping fixture 3. Then, the translation drive component 62 drives the translation connecting plate 63 to move to the right, thereby driving the two groups of measuring components 64 to move to the right. The two groups of measuring components 64 correspond to the front and back sides of the mobile phone respectively. The laser measuring instrument 645 can detect the mobile phone. During the operation, the translation top plate 643 can operate smoothly and stably through the cooperation of the movable slide rail 642 and the fixed slider 641, thereby improving the detection accuracy. When replacing a mobile phone of a different model for detection, the position and direction of the laser measuring instrument 645 can be quickly adjusted through the angle adjustment component 644, thereby improving the adjustment efficiency of the laser measuring instrument 645.

The inner side of the measuring instrument fixing plate 6443 is chamfered.

[0042] By adjusting the position of the second vertical plate 6442 on the first vertical plate 6441, the height of the laser measuring instrument 645 can be adjusted. By adjusting the position of the measuring instrument fixing plate 6443 on the second vertical plate 6442, the front and rear position of the laser measuring instrument 645 can be adjusted. When the angle of the laser measuring instrument 645 needs to be adjusted, loosen the screws on the arc-shaped strip hole 64431 and the round hole 64432 so that the laser measuring instrument 645 can rotate around the screw on the round hole 64432. When it is rotated to a suitable angle, tighten the screw again to complete the angle adjustment of the laser measuring instrument 645. The inner side of the measuring instrument fixing plate 6443 is chamfered to make as much space as possible for the installation and adjustment of the laser measuring instrument 645, and it is also convenient to observe the operating status of the laser measuring instrument 645 when the equipment is running.
