The embodiment provides a clamping jig. As shown in fig. 1-3, the clamping fixture includes a worktable 1 and a clamping assembly 2. Clamping component 2 sets up in workstation 1, clamping component 2 includes mounting 21, slider 22, joint spare 23 and locating part 24, mounting 21 sets up in workstation 1, slider 22 slides and sets up in mounting 21, slider 22 is provided with spacing portion 221, locating part 24 sets up in mounting 21, joint spare 23 rotates and sets up in slider 22 and is located between spacing portion 221 and the locating part 24, when slider 22 is in the primary importance, joint spare 23 can rotate and keep away from spacing portion 221 in order to have the open position, when slider 22 is in the second place, joint spare 23 is by spacing portion 221 and locating part 24 clamping in order to have the joint position.

In the clamping jig, the clamping piece 23 can rotate from the open position to the clamping position according to the sliding of the sliding block 22 so as to fix the upper mobile phone screen 100 of the workbench 1. When the mobile phone screen 100 needs to be detected, the operator places the mobile phone screen 100 on the workbench 1 and slides the slider 22 to the second position. At this time, the clamping member 23 moves along with the slider 22, the limiting member 24 abuts against the clamping member 23 to drive the clamping member 23 to rotate towards the limiting portion 221, and when the clamping member 23 is clamped by the limiting member 24 and the limiting portion 221, the clamping member 23 clamps the mobile phone screen 100 on the workbench 1 to be fixed. When the mobile phone screen 100 needs to be taken out, the operator slides the slider 22 to the first position, and then rotates the clip 23 in a direction away from the limiting portion 221 to rotate the clip 23 to the open position, so that the mobile phone screen 100 can be taken out.

The clamping fixture is simple in structure, the state of one clamping assembly 2 can be controlled only through movement in one direction, and the sliding block 22 cannot collide with the mobile phone screen 100.

It is understood that the slider 22 may be raised above the table 1 during the sliding process to lift the mobile phone screen 100 for easy access by the operator. In order to prevent the slider 22 from striking the mobile phone screen 100 to damage the mobile phone screen 100, a buffer block is arranged at the top end of the slider 22.

However, the thicknesses of the mobile phone screens 100 of different models of mobile phones are different, and if the mobile phone screen 100 with a thinner thickness is to be detected, when the clamping piece 23 is in the clamping position, the sliding block 22 can be continuously moved downwards, so that the clamping piece 23 can be moved downwards to be matched with the workbench 1 to clamp the thinner mobile phone screen 100.

Preferably, the latch assembly 2 further comprises a driving member capable of bringing the latch member 23 into the open position when the slider 22 is in the first position.

As shown in fig. 2 and fig. 3, the driving member is a weight 231, and the weight 231 is disposed on a side of the clamping member 23 away from the limiting portion 221. The counterweight 231 can make the center of gravity of the clamping member 23 be located at one side of the rotation axis of the clamping member 23 close to the limiting member 24, when the slide block 22 slides to the first position, the clamping member 23 rotates towards the open position under the action of gravity, and an operator can directly take out the mobile phone screen 100, so that the mobile phone screen is convenient and fast.

Optionally, the driving member is a spring, two ends of the spring respectively abut against the clamping member 23 and the limiting portion 221, the clamping member 23 is driven when the slider 22 is at the first position, and the spring can enable the clamping member 23 to be at the open position.

Preferably, the position-limiting member 24 is a bearing, and the bearing is rotatably disposed on the fixing member 21 and is in rolling contact with the engaging member 23. The clamping member 23 moves up and down along with the slider 22, and moves relative to the limiting member 24, so that the contact surface between the clamping member 23 and the limiting member 24 is worn. After wearing and tearing for a long time, the increase of distance between locating part 24 and the joint spare 23 leads to locating part 24 can't drive joint spare 23 to vertical joint position again easily to influence the fixed effect of cell-phone screen 100. And the bearing can become the rolling friction with the sliding friction between locating part 24 and the joint spare 23, reduces wearing and tearing by a wide margin, increase of service life.

Because the slide block 22 is positioned inside the workbench 1, an operator can directly operate the slide block by hands, which is inconvenient and easy to cause safety accidents. In order to solve the problem, the clamping assembly 2 further comprises an air cylinder 25, a cylinder body of the air cylinder 25 is fixedly arranged on the fixing member 21, and a piston rod of the air cylinder 25 is fixedly connected with the sliding block 22. This joint subassembly 2 passes through cylinder 25 and drives the lift of slider 22 as the power supply, greatly reduced operating personnel's working strength, and guaranteed operating personnel's safety.

Furthermore, the clamping components 2 are provided with four, two clamping components 2 are arranged on one side of the workbench 1, and the other two clamping components 2 are arranged on the other side of the workbench 1. The four clamping components 2 can be clamped at four corners of the mobile phone screen 100, so that the mobile phone screen 100 is fixed more stably and firmly.

Wherein, the cylinders 25 of the four clamping components 2 are all communicated with an air pump, and the air pump can synchronously control the movement of the piston rod of each cylinder 25. The operator can control the lifting of the piston rods of the four cylinders 25 by controlling the opening and closing of the air pump, so that the clamping pieces 23 of the four clamping components 2 synchronously rotate, and the mobile phone screen 100 is opened or clamped simultaneously.

As shown in fig. 4-7, for maintenance and repair, the clip assembly 2 further includes a connecting member 26, the connecting member 26 is disposed at an end of the piston rod, and the connecting member 26 is detachably connected to the sliding block 22. The piston rod and the sliding block 22 generally have no connecting structure and can only be fixed by welding. The operator can design a connecting member 26 capable of connecting the sliding block 22 and the piston rod independently, so that when the clamping assembly 2 needs to be maintained and repaired, the operator can disassemble the connection between the cylinder 25 and the sliding block 22 through the connecting member 26.

Specifically, joint groove 261 has been seted up along the axial in the outside of connecting piece 26, and slider 22 is provided with connecting portion 222, and U type groove 223 has been seted up along the horizontal direction to connecting portion 222, and connecting piece 26 sets up in U type groove 223, and connecting portion 222 butt joint groove 261's cell wall. When the operator needs to remove the clamping assembly 2, he only needs to move the slide 22 horizontally to slide the connecting piece 26 out of the U-shaped groove 223.

Preferably, the fixing member 21 has a chute along the vertical direction, the fixing member 21 has a sliding block 22 protruding, and the sliding block 22 is slidably disposed in the chute. The spout can play the guide effect to slider 22, can not take place the skew when guaranteeing slider 22 and slide along vertical direction to prevent that slider 22 or joint spare 23 striking cell-phone screen 100 from causing the damage.

It can be understood that a certain clamping force is required between the clamping member 23 and the working platform 1 to fix the mobile phone screen 100, and the clamping force is easy to damage the mobile phone screen 100. To solve this problem, the table 1 is provided with a cushion pad. When the clamping piece 23 is clamped with the mobile phone screen 100, the buffer cushion is compressed, so that the clamping force is provided by the elastic force of the buffer cushion, and the clamping force is gradually increased along with the descending of the sliding block 22, thereby greatly reducing the possibility of damage to the mobile phone screen 100.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention, and it is to be understood that the present invention is not limited to the above embodiments, but may be modified within the scope of the present invention.
