There is also an end nozzle arranged at 90 degrees to the main nozzle.

[0059] The air drying mechanism uses the conveying roller in the air drying area as the conveying medium. When it is transported to the front end of the air drying mechanism station, the air drying starts, and the air knife blows compressed air to the outer surface of the crystal tray for air drying. When the crystal tray passes through this air drying mechanism station, there will be a seam switch detection to turn off the air supply switch of the air knife, and the clean crystal tray is transported to the next station for reuse.

The high-frequency heating coil 102 is turned on for heating, and the crystal tray 8 is heated while being transported (the glue between the crystal tray 8 and the adhesive sheet can be automatically invalidated by heating) to achieve automatic separation of the adhesive sheet and the crystal tray 8, until it is transported to the stop position on the conveying roller in the heating zone. The crystal tray 8 is completely heated in the length direction, and the high-frequency heating is completed; the stop position The stop limiter falls and is transported to the next station. The material separation area conveyor roller 202 on the adhesive board stacking mechanism 2 stops the crystal support 8. The adhesive board removal Z-axis assembly 206 on the adhesive board stacking mechanism 2 drops into place. The gripper 204 clamps the adhesive board. The adhesive board removal Z-axis assembly 206 rises. The adhesive board removal X-axis assembly 205 moves the adhesive board to the top of the storage trolley 201.

The grabbing cylinder A605 rises with the wafer tray 8, and the stop limiter on the conveying roller of the rinsing area falls. The door 301 of the rinsing box 3 opens, and the grabbing cylinder A605 places the wafer tray 8 in the wafer tray placement position driven by the walking group. Driven by the walking group, the grabbing gripper A606 leaves the rinsing box and resets. The door 301 of the rinsing box 3 closes, and preparations are made for high-pressure rinsing of the wafer tray 8. Preparation work, the degumming mechanism 7 starts working, the high-pressure water pump in the high-pressure water tank starts working, the top nozzle 708 and the end nozzle 709 start working, the top nozzle 708 and the end nozzle 709 are two-hole rotating flushing high-pressure nozzles, which can cover a 50mm flushing and degumming area, and the degumming surface of the crystal tray 8 to be degummed is flushed and degummed. The flushing divides the crystal tray 8 into two areas for flushing. The flushing order is to clean the 90-degree angle of the starting end of the crystal tray 8, the side of the crystal tray 8 in the first area, the top surface of the crystal tray 8 in the first area, another 90-degree angle in the first area, the 90-degree angle in the second area, and the side of the crystal tray 8 in the second area. , another 90-degree angle in the second zone, after all surfaces are debonded, the high-pressure water pump stops supplying water, the debonding mechanism 7 drives the water spray assembly to return to the initial position, the door 301 of the flushing box 3 is opened, and the flushing box 3 is loaded and unloaded again; the grabbing gripper A606 on the flushing loading and unloading mechanism 6 carries the uncleaned wafer support 8 into the cleaning box, and the grabbing gripper B607 on the flushing loading and unloading mechanism 6 grabs the cleaned wafer support 8. After the grabbing gripper B607 grabs the cleaned wafer support 8, the X-axis assembly 602 on the flushing loading and unloading mechanism 6 drives the Z-axis assembly 603 to move backward as a whole, and the grabbing gripper A606 is moved backward. 06 The unwashed wafer tray 8 is placed in the wafer tray placement position. The grabber A606, driven by the walking group, leaves the rinsing box and resets. The door 301 of the rinsing box 3 closes, and the next cleaning process begins. The cleaned wafer tray 8 is placed on the rinsing area conveyor roller by the grabber B607. From the rinsing area conveyor roller, it is conveyed to the air-drying area conveyor roller for air-drying. Air-drying uses a fixed air knife and compressed air to dry the top, bottom, left, and right sides of the wafer tray 8. After passing through the air-drying mechanism 4 station, the wafer tray 8 is a clean wafer tray 8 and will be transferred to the next process for reuse.
