Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, and in particular to a laser-assisted MicroLED mass processing positioning device. Background Art

[0002] Laser-assisted MicroLED mass transfer is a key process in MicroLED display technology. It uses laser technology to assist in the mass transfer of MicroLED chips. A large number of MicroLED chips are grown on the source growth substrate, and then these chips are accurately peeled off from the source substrate and transferred to the driving circuit of the target display substrate using laser technology. Finally, the transferred chips are integrated with the target display substrate by bonding to form a MicroLED display panel.

[0003] During the production process of MicroLED display panels, certain parts need to be positioned and fixed, and positioning devices are often used. The positioning device can accurately fix the position of the workpiece to prevent the workpiece from moving or deforming during the processing, thereby improving the precision and accuracy of the work.

[0004] The prior art patent document with publication number CN217290977U provides a laser processing part positioning device, which connects the lower pressure plate to the two connecting vertical plates through two connecting springs by setting a pressing device, and the lower pressure plate is located below the pressing device. Since the special-shaped extrusion block on the pressing device is a special-shaped protrusion structure, when the operator rotates the pressing device to press down, the change in the angle of the special-shaped protrusion on the special-shaped extrusion block synchronously presses the lower pressure plate to press the plate down to position it. At the same time, the limit push plate can effectively perform auxiliary positioning under the action of the electric telescopic rod. The positioning speed is fast and easy to adjust, which is beneficial to improving the laser cutting efficiency of the plate.

[0005] In the above-mentioned prior art, when the operator rotates the pressing device to press down, the angle of the special-shaped protrusion on the special-shaped extrusion block changes synchronously to press down the lower pressing plate to press the plate to position it, and at the same time, the limit push plate can effectively perform auxiliary positioning under the action of the electric telescopic rod. However, when the positioning device in the patented technology needs to be pressed down, the staff needs to continuously press it down manually. Long-term use will consume the staff's physical strength, which will cause the downward pressure to become loose, reducing the positioning effect. Therefore, we need a laser-assisted MicroLED mass processing positioning device. Utility Model Content
