Abstract

The present invention proposes a laser processing device for a ceramic substrate for a circuit board.

By setting a vacuum boss, the ceramic substrate can be tightly attached to the fixture plate under the action of the air pressure difference, thereby avoiding the position displacement of the ceramic substrate due to vibration. By setting the first optical fiber assembly and the second optical fiber assembly to be aligned at the same height, the loading height and unloading height of the loading and unloading assemblies can be ensured to be consistent, thereby ensuring the stability of the loading and unloading process. By setting a height sensor, it is possible to accurately detect whether the ceramic substrates placed at the processing station are overlapping or tilted, and issue an alarm in time to remind the staff to clear the obstacles and ensure the normal processing.

Ceramic substrates have the characteristics of good insulation performance, high thermal conductivity, strong current carrying capacity and high adhesion strength, and can be etched into various patterns according to actual needs. Therefore, ceramic substrates are widely used in various industries, including the communications industry, home appliance industry, computer industry and electronic component industry.

[0003] Laser processing refers to cutting, welding, surface treatment or drilling of processed materials by using the characteristics of the interaction between laser beam and matter.

[0029] In the present invention, the single rotation angle of the rotary cylinder is preset to 90 degrees, so as to cooperate with the rotation of the right-angle plate to drive the first suction cup assembly and the second suction cup assembly to load and unload materials.

[0030] Before the loading and unloading mechanism is turned on, the first suction cup assembly is in the initial position (when the first suction cup assembly is directly above the first supporting assembly), and the second suction cup assembly is in the initial position; when the Y-axis assembly transfers the positioning mechanism to directly below the second suction cup assembly, the loading and unloading assembly starts to work; at this time, the first suction cup assembly absorbs the unprocessed ceramic substrate on the first supporting assembly, and the second suction cup assembly absorbs the processed ceramic substrate on the positioning mechanism, and then the lifting cylinder moves to drive the right-angle plate to rise; when the lifting cylinder moves to the maximum displacement The rotary cylinder rotates 90 degrees counterclockwise, and then the lifting cylinder resets; at this time, the first suction cup assembly places the unprocessed ceramic substrate on the processing station, and the second suction cup assembly places the processed ceramic substrate on the second supporting assembly; then the height sensor detects the thickness of the ceramic substrate placed on the processing station to prevent the ceramic substrates from overlapping or tilted, so as to ensure the normal processing; when the height sensor detection is completed, the lifting cylinder drives the right-angle plate to rise again, and then the rotary cylinder resets, the lifting cylinder resets, and each component returns to its initial position.

[0040] Furthermore, the first supporting assembly includes a first connecting plate and a first supporting plate; one end of the first connecting plate is connected to the output end of the first KK module, and the other end passes through the first flat plate and is connected to the first supporting plate.

[0046] The present invention proposes a laser processing device for a ceramic substrate for a circuit board. By setting the two ends of a positioning push rod to respectively abut against the first forward push assembly and the second forward push assembly, the positioning push rod can push the ceramic substrate smoothly into the predetermined position of the fixture plate in one step under the push of the positioning cylinder, thereby eliminating unnecessary steps. By setting a vacuum boss, the ceramic substrate can be tightly attached to the fixture plate under the action of the air pressure difference, thereby avoiding the position displacement of the ceramic substrate due to vibration. By setting the first optical fiber assembly and the second optical fiber assembly to be aligned at the same height, the loading height and unloading height of the loading and unloading assemblies can be ensured to be consistent, thereby ensuring the stability of the loading and unloading process. By setting a height sensor, it is possible to accurately detect whether the ceramic substrates placed at the processing station are overlapping or tilted, and issue an alarm in time to remind the staff to clear the obstacles and ensure normal processing.
