[0015] The present invention provides a laser coding fixture for silicon-based OLEDs. It has the following beneficial effects:

[0016] (1) The invention sets a placement device so that the rotating wheel drives the L-shaped clamping rod to rotate toward each other on the outer wall of the connecting rod. After the smoke hood moves to the bottom, the L-shaped clamping rod will be stuck in the arc-shaped clamping groove on the smoke hood, and then the laser scanner is turned on by controlling the display to mark the OLED screen on the PCB integrated board. By setting the placement ring, the PCB integrated board can be quickly fixed, and the placement tilt caused by the unevenness of the electronic components at the bottom of the PCB integrated board can be avoided, thereby realizing efficient and accurate two-dimensional code marking. The positioning plate will contact the flexible surface of the card block, thereby passing over the card block. After the limit plate moves to the top, the L-shaped card rod and the arc-shaped card slot of the smoke hood generate a repulsive pulling force, and the arc surface of the arc-shaped card slot can allow the L-shaped card rod to break away from the restriction of the arc-shaped card slot. The ejection plate thereby drives the PCB integrated board that has been coded to be ejected. The setting of the card block can prevent the PCB integrated board from sliding into the bottom of the slide slot of the fixture table again after being ejected. The setting of the ejection plate not only improves the production efficiency, but also avoids the risk of damage caused by manual operation, thereby ensuring the continuity and stability of the production process.

[0017] (2) The invention provides a purification device. When the smoke hood is lowered to the bottom, the micro suction machine is turned on to suck the smoke inside the smoke hood into the inside of the suction pipe. Then the small motor is turned on to drive the rotating rod to rotate. The rotating rod drives the fan blades to rotate. The fan blades suck the harmful gas in the purification pipe upward. The harmful gas passes through the filter plate to isolate the smoke. The activated carbon particles inside the ventilation plate are used to purify the harmful gas, which effectively reduces the harm of harmful gas and smoke to operators and the working environment, improves production safety and environmental protection, relieves the downward pressure on the ventilation plate, and is reset upward by the elastic force of the spring on the filter plate. The activated carbon particles will flip up and down quickly. This up and down flipping action helps the activated carbon particles to contact with harmful gases more effectively, thereby improving air purification efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

If these harmful gases are not handled in time, they will cause harm to the human body and the workshop environment. Therefore, when the smoke hood 16 is lowered to the bottom, the micro suction machine 34 is turned on, and the micro suction machine 34 sucks the smoke inside the smoke hood 16 into the suction pipe 33, and then the small motor 36 is turned on.

This up and down flipping action helps the activated carbon particles to contact with harmful gases more effectively, thereby improving the air purification efficiency.

[0034] When the present embodiment is working, when laser coding is performed, a high-energy laser beam is irradiated onto the PCB screen, which will cause part of the material on the surface of the material to evaporate instantly or undergo a chemical reaction, thereby generating smoke and possible harmful gases. If these harmful gases are not handled in time, they will cause harm to the human body and the workshop environment. Therefore, when the smoke hood 16 is lowered to the bottom, the micro suction machine 34 is turned on, and the micro suction machine 34 sucks the smoke inside the smoke hood 16 into the interior of the suction pipe 33, and then the small motor 36 is turned on, and the small motor 36 drives the rotating rod 37 to rotate, and the rotating rod 37 drives the fan blades 38 to rotate, and the fan blades 38 suck the harmful gases in the purification pipe 32 upward, and the harmful gases pass through the filter plate 39 to isolate the smoke, and then the harmful gases are purified by the activated carbon particles inside the ventilation plate 311, which effectively reduces the harm of harmful gases and smoke to operators and the working environment, and improves production safety and environmental protection.

[0035] When the rotating rod 37 rotates, the rotating rod 37 drives the triangular abutment plate 314 to rotate, and the triangular abutment plate 314 abuts against the arc-shaped abutment rod 313 on the connecting rod 312, so that the arc-shaped abutment rod 313 drives the connecting rod 312 to move downward, and the connecting rod 312 drives the ventilation plate 311 to move downward, and the ventilation plate 311 drives the activated carbon particles on its top to move downward. After the triangular abutment plate 314 passes over the arc-shaped abutment rod 313, the ventilation plate 311 is relieved of the downward pressure, and at the same time, it is reset upward by the elastic force of the spring 310 on the filter plate 39, and the activated carbon particles will quickly flip up and down. This up and down flipping action helps the activated carbon particles to contact with harmful gases more effectively, thereby improving the air purification efficiency.
