[0010] Furthermore, a slot is provided on one side of the light hole on the pressing plate, and the slot is connected to the light hole.

[0011] Furthermore, the cross-sectional shapes of the positioning seat and the pressing plate are both circular.

[0012] Furthermore, the outer diameter of the positioning seat is the same as the outer diameter of the pressing plate.

[0013] A method for applying glue to a gluing tray for bonding an aluminum sheet to a phenolic bakelite retainer, characterized in that the method comprises the following steps:

[0014] Step 1: Select a glue-coated tray of corresponding size according to the size of the phenolic bakelite cage;

[0015] Step 2: Place the base plate horizontally, remove the pressure plates from the multiple positioning mechanisms, and place a phenolic bakelite retainer on each positioning seat, with the lower end of the phenolic bakelite retainer sleeved on the outer side of the positioning boss;

[0016] Step 3: inputting the position parameters of the multiple positioning mechanisms into the operating system of the glue coating machine, and using the glue coating machine to squeeze glue onto the upper end surface of each phenolic bakelite cage;

[0017] Step 4: Place an aluminum sheet on the upper end surface of each phenolic bakelite cage;

[0019] Step 6: After the glue is completely solidified, remove the pressing plate and remove the phenolic bakelite retainer to which the aluminum sheet is bonded.

[0020] Furthermore, when installing the pressing plate in step five, the pressing plate is moved horizontally, and the fastening bolts are inserted from the notches of the slots until they move to the position of the light holes.

A plurality of positioning mechanisms are evenly distributed in a matrix on the tray, and a plurality of phenolic bakelite retainers can be positioned simultaneously so as to apply glue to the plurality of retainers. The arrangement of a pressing plate ensures that the thickness of the glue layer between the retainer and the aluminum sheet is uniform, thereby ensuring stable product quality and meeting the requirements for the final dimensional stability of each product after gluing. In combination with the use of a gluing machine, the gluing time is reduced while the quantitative glue extrusion is ensured, thereby effectively preventing the glue from solidifying.
