Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, specifically a multi-piece simultaneous uniform coating spin coater. Background Technology

[0002] Spin coating is short for rotary application method. A spin coating machine with application number 201920738675.4, relating to the field of spin coating machine technology, includes a power box, a vacuum box, a tray box, and a dispensing device. A rotary motor is fixedly installed inside the power box, and a first rotating shaft is fixedly installed on the output shaft of the rotary motor. A second rotating shaft is detachably installed at the end of the first rotating shaft away from the rotary motor, and a vacuum tray is fixedly installed at the end of the second rotating shaft away from the second rotating shaft. By providing a vacuum box, excess adhesive, if drawn in due to excessive suction, will accumulate inside the vacuum box, preventing it from directly entering the vacuum pump and causing damage. The detachable first and second rotating shafts facilitate the removal of the second rotating shaft for cleaning its internal cavity, preventing blockage and affecting the operation of the vacuum suction cup. However, it is not convenient for simultaneously applying adhesive to the surfaces of multiple products, resulting in low coating efficiency. Utility Model Content

The upper surface of the tray 3 is provided with multiple glue-applying grooves 5, which are used to laterally clamp and position multiple product pieces to be coated. The thickness adjustment plate 4 is used to adjust the glue-applying end face of the product piece to be coated to be flush with the upper surface of the tray 3. The glue is dripped onto the middle of the tray 3. The tray 3 is driven to rotate at high speed by the motor 10 and the gear set 9, which can simultaneously rotate and apply glue to the upper surface of multiple product pieces to be coated, resulting in high glue-applying efficiency.

[0023] like Figure 1 and Figure 3 As shown, in order to unload the glued products in the glue coating tank 5, a thickness adjustment plate 4 is provided at the bottom of the glue coating tank 5 via a lifting mechanism.
