[0027] As mentioned above, in this case, when the keyboard 2 is used, it is placed on the placement table 102 and attached to the fixing plate 103, and then the screw rod 301 is rotated, and the gear 302 is rotated accordingly, and the moving block 303 moves on the screw rod 301 accordingly, and the movement of the moving block 303 drives the top moving plate 306 to move, and the clamping plate 2 307 on the moving plate 306 moves accordingly, and the rotation of the gear 302 causes the upper and lower toothed plates 304 to move relatively accordingly, and the clamping plate 1 305 on the toothed plate 304 also moves accordingly. At this time, the two clamping plates 1 305 and the clamping plate 2 307 clamps the keyboard 2 in three directions respectively, and then starts the electric push rod 4 to push the detection component 5 at the bottom to detect the keycap 201. The device has strong linkage, can realize multi-sided clamping, and has strong firmness. When the keyboard 2 is placed without being attached to the fixed plate 103, the clamping plate 2 307 also pushes the keyboard 2 to fit the fixed plate 103 during the movement. The clamping plates 1 305 at both ends can also be pushed and clamped during the clamping process, so that the clamping position is more accurate, ensuring that there will be no error in the detection position, thereby improving the detection efficiency.

[0028] like Figure 2-Figure 6 As shown, two slide bars 3072 pass through the movable plate 306, one end of the two slide bars 3072 is fixed on the clamping plate 307, a spring 308 is connected between the slide bar 3072 and the movable plate 306, the detection component 5 includes an air pump 501 fixed to the bottom of the electric push rod 4, a strip plate 502 is fixed to the bottom of the air pump 501, a plurality of detection heads 503 are fixed to the bottom of the strip plate 502, a rubber block 3071 is fixed to one side of the clamping plate 307, and fixed rods 309 are fixed on both sides of the inside of the workbench 1, and the fixed rods 309 are inserted into the opening of the tooth plate 304 to form a sliding connection.

[0029] As mentioned above, the clamping plate 307 is stably connected to the movable plate 306 through the sliding rod 3072 and the spring 308, and the addition of the spring 308 can increase the adjustment amount of the clamping plate 307, and fixing the rubber block 3071 on one side of the clamping plate 307 can increase the clamping performance and prevent damage to the components. The electric push rod 4 is started to move downward, and the bottom strip 502 moves downward accordingly. The detection head 503 at the bottom of the strip 502 is pressed down to press the keycap 201, and then it is checked whether there is any keycap 201 that has not rebounded when it is lifted up. This process detects the rebound performance of the keycap 201. After pressing down, the air pump 501 is started to form a negative pressure and then lifted up, so that the fixing of the keycap 201 can be checked, and the fixing rod 309 can make the tooth plate 304 run smoothly horizontally.

The detection head 503 corresponds to the keycap 201 in a one-to-one manner in the vertical direction.

[0031] As mentioned above, the turntable 3011 facilitates the stable rotation of the screw rod 301 during operation. The rotation of the turntable 3011 has a certain resistance to prevent the turntable 3011 from rotating due to non-human factors and affecting the setting of the transparent box door 101, so as to facilitate the observation of the internal components, facilitate timely maintenance of the internal parts, and extend the service life of the device. The end of the screw rod 301 close to the box door 101 is rotatably connected with the mounting plate fixed inside the workbench 1.

[0032] Working principle: In this case, when the keyboard 2 is placed on the placement table 102 and attached to the fixing plate 103, the turntable 3011 is rotated to control the screw rod 301 to rotate, and the gear 302 also rotates accordingly, and the upper and lower toothed plates 304 also move relatively, and the clamping plate 1 305 also moves accordingly, and the screw rod 301 rotates, and the moving block 303 moves on the screw rod 301 accordingly, and the movement of the moving block 303 drives the top moving plate 306 to move, and the clamping plate 2 307 moves accordingly At this time, the two clamping plates 1 305 and the clamping plate 2 307 clamp the keyboard 2 in three directions respectively, and then the electric push rod 4 is started to move downward, and the bottom strip 502 moves downward accordingly. The detection head 503 at the bottom of the strip 502 is pressed down to press the keycap 201, and then it is checked whether there is any keycap 201 that has not rebounded when it is lifted up. This process detects the rebound performance of the keycap 201. After pressing down, the air pump 501 is started to form a negative pressure and then lifted up, so that the fixing condition of the keycap 201 can be checked.
