[0030] Support seat 100 is installed on lifting mechanism, when taking material, support seat 100 is driven to descend by lifting mechanism, until pressing block 230 abuts and presses down workpiece 300 on tray, since the both ends of spring 240 are respectively abutted with bracket 210 and pressing block 230, pressing block 230 is driven to move upwards relative to bracket 210 by the reaction force of workpiece 300, so that spring 240 is compressed, then two clamping jaws 110 are driven to move mutually close by driving part, so that two clamping jaws 110 clamp workpiece 300 from the diagonal sides of workpiece 300, and workpiece 300 is supported by clamping jaw 110, then support seat 100 is driven to ascend by lifting mechanism, to drive workpiece 300 to ascend and separate from tray, so that the clamping of workpiece 300 is completed, when transferring, workpiece 300 is pressed down by the elastic force of spring 240, and workpiece 300 is flattened by clamping jaw 110, which can improve the flatness of clamped workpiece 300, to reduce the possibility of workpiece 300 tilting and rising, thereby improving the stability of feeding and discharging.

[0031] It should be noted that in use, the support seat 100 can be installed on the lifting mechanism, and the support seat 100 is driven to lift by the lifting mechanism to drive the clamped workpiece 300 to lift.

[0032] The lower end of the clamping jaw 110 can be provided with a support portion for supporting the workpiece 300. During transfer, the workpiece 300 can be flattened by cooperating with the clamping jaw 110. When clamping the workpiece 300, the support portion needs to be extended below the workpiece 300, and then the two clamping jaws 110 are driven to move close to each other by the driving member to clamp the workpiece 300.

[0033] The preset distance between the bottom surface of the pressing block 230 and the bottom of the clamping jaw 110 can be equal to the vertical height of the workpiece 300, so that the workpiece 300 can abut against the pressing block 230 but is not subjected to the downward pressure of the pressing block 230. When the workpiece 300 is tilted and raised, it will drive the pressing block 230 to move upward relative to the support 210, so that the spring 240 is compressed. The spring 240 drives the pressing block 230 to press the workpiece 300, so that the workpiece 300 is adjusted to a flat state, thereby improving the flatness of the workpiece 300.

[0034] The driving member can be a cylinder, an oil cylinder or a motor, etc., which can drive the two clamping jaws 110 to move close to or away from each other to clamp or release the workpiece 300.

[0035] It can be understood that, referring to Figure 2 and Figure 3 , the support 210 is provided with a waist-shaped hole 211 extending in the vertical direction. The waist-shaped hole 211 is provided with a positioning bolt 250, and the positioning bolt 250 is threadedly connected to the support seat 100. The positioning bolt 250 can abut against the support 210 to fix the vertical position of the support 210. Since the waist-shaped hole 211 is provided with the positioning bolt 250, and the positioning bolt 250 is threadedly connected to the support seat 100, the support 210 is moved in the vertical direction to make the positioning bolt 250 slide in the waist-shaped hole 211 until the pressing block 230 is adjusted to the preset position. By tightening the positioning bolt 250, the positioning bolt 250 abuts against the support 210 to fix the vertical position of the support 210. The vertical distance between the pressing block 230 and the bottom of the clamping jaw 110 can be adjusted to adjust the compression amount of the spring 240, thereby adjusting the spring force of the spring 240, and further adjusting the pressure of the pressing block 230 on the workpiece 300 to adapt to different pressure requirements.

[0036] It should be noted that the distance between the bottom surface of the support 210 abutting against the spring 240 and the top surface of the pressing block 230 abutting against the spring 240 can be adjusted to adjust the compression amount of the spring 240, thereby adjusting the spring force of the spring 240, and further adjusting the pressure of the pressing block 230 on the workpiece 300.

[0037] It can be understood that, referring toFigure 2 And Figure 6 The shape of the pressing block 230 is U-shaped. By abutting the side edge position of the workpiece 300 through the U-shaped pressing block 230, the workpiece 300 is flattened, the contact area between the pressing block 230 and the workpiece 300 is increased, the stability of leveling is improved, and the influence of the pressing block 230 on the electronic devices in the middle of the workpiece 300 is reduced.
