Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a glue dipping device for the production of copper clad laminates as shown in Figures 1 to 4 and includes:

[0027] A conveying rack for conveying the processed sheets of copper clad laminates;

[0028] A gluing device located above the conveying rack for gluing the processed sheets of copper clad laminates;

[0029] The gluing device includes a roller 1 and a glue storage cylinder 2. Both ends of the roller 1 are rotatably connected with mounting frames 3 through bearings. The glue storage cylinder 2 penetrates through the roller 1 and extends outward. Both ends of the glue storage cylinder 2 are rotatably connected with mounting brackets 4 through bearings. The mounting brackets 4 are fixed to the outside of the mounting frames 3. Pressing type glue outlets 5 are installed around the outside of the glue storage cylinder 2. Glue storage grooves 6 corresponding to the pressing type glue outlets 5 are opened around the inner cavity of the roller 1. A plurality of glue outlet holes 7 communicating with the glue storage grooves 6 are opened on the outside of the roller 1. One end of the glue storage cylinder 2 is rotatably connected with a connecting piece 8 through a bearing. The end of the connecting piece 8 away from the glue storage cylinder 2 is communicated with an extending outward glue conveying pipe 9. A driving component 10 for driving the glue storage cylinder 2 is arranged at one end of the roller 1;

[0030] And an adjusting component 11 for adjusting the positions of the gluing device and the conveying rack;

[0031] By installing the roller 1 and the glue storage cylinder 2 above the conveying rack, the rotation of the glue storage cylinder 2 drives the rotation of the roller 1. At the same time, when the glue storage cylinder 2 drives the roller 1 to rotate, the two squeeze the pressing type glue outlets 5, so that the pressing type glue outlets 5 introduce the glue liquid stored in the glue storage cylinder 2, discharge it from the roller 1 through the glue outlet holes 7 and attach it to the surface of the roller 1. By using the rotation of the roller 1, the glue liquid is then transferred to the surface of the processed sheet. It can not only control the amount of glue liquid and save costs, but also effectively avoid damage to the glue surface by performing gluing treatment on one side of the processed sheet.

[0032] The driving component 10 includes a driving motor 101 installed inside the mounting bracket 4. The output shaft of the driving motor 101 penetrates through the mounting bracket 4 and is fixed with a driving gear 102. One end of the glue storage cylinder 2 is fixed with a driven gear 103. The sides of the driven gear 103 and the driving gear 102 facing each other are meshed with each other. The driving motor 101 drives the driving gear 102 to rotate, and then the driving gear 102 drives the driven gear 103 to drive the glue storage cylinder 2 to rotate inside the roller 1.

[0033] The conveying rack includes a fixed bottom frame 12. Two support rollers 13 are rotatably connected to the inner cavity of the fixed bottom frame 12 through bearings. A conveyor belt 14 is sleeved on the outside of the support rollers 13 for conveying the processed sheets of copper clad laminates. A conveying motor connected to the end of one group of support rollers 13 is fixed to the side of the fixed bottom frame 12. The support rollers 13 are driven to rotate by the conveying motor, and then the conveyor belt 14 is driven to convey the processed sheet.

[0034] A groove is provided on the outer side of the roller 1. A sponge sleeve 15 is sleeved in the inner cavity of the groove. The sponge sleeve 15 can be limited by the groove, and then adsorbed by the glue of the sponge sleeve 15. At the same time, squeezing the sponge sleeve 15 can apply the glue on the surface of the processed plate.

[0035] A fixed frame 16 is fixed on the top of the fixed bottom frame 12. The installation frame 3 is located inside the fixed frame 16. Limit rods 17 are fixed on the four sides of the top of the installation frame 3. The top of the limit rods 17 penetrates through the fixed frame 16 and extends upward. The installation frame 3 can be limited by the limit rods 17 to keep the installation frame 3 and the limit frame stable in the vertical direction, which is convenient for adjusting the installation frame 3 up and down.

[0036] The adjusting assembly 11 includes two sets of threaded sleeves 111 embedded in the top of the fixed frame 16. A threaded rod 112 is threadedly connected in the inner cavity of the threaded sleeve 111. The bottom of the threaded rod 112 penetrates through the threaded sleeve 111 and is rotatably connected to the top of the installation frame 3 through a bearing. A turning handle 113 is fixed on the top of the threaded rod 112. Through the cooperation of the threaded rod 112 and the threaded sleeve 111, it is convenient to adjust the height of the installation frame 3 by rotating the threaded rod 112, so as to adjust the distance between the roller 1 and the conveyor belt 14, and the glue can be applied to processed plates of different thicknesses.

[0037] The rotating shafts of the roller 1 and the glue storage cylinder 2 are not coaxial. A plurality of supporting rollers 18 are rotatably connected to the inner cavity of the fixed bottom frame 12 through bearings. The supporting rollers 18 are located below the roller 1. By limiting the positions of the roller 1 and the glue storage cylinder 2, it is ensured that the pressing type glue outlet head 5 on the outer side of the glue storage cylinder 2 controls the glue outlet according to the change of the positions of the glue storage cylinder 2 and the roller 1. At the same time, the supporting rollers 18 can support the conveyor belt 14 to ensure that the processed plate on the top of the conveyor belt 14 can be attached to the roller 1.

[0038] During specific use, start the conveying motor. The conveying motor drives the conveyor belt 14 through the supporting roller 13 to convey and transfer the processed plate. At the same time, start the driving motor 101. The driving motor 101 drives the glue storage cylinder 2 to rotate through the driving gear 102 and the driven gear 103. The pressing type glue outlet head 5 moves into the glue storage groove 6 as the glue storage cylinder 2 rotates. At the same time, the roller 1 squeezes the pressing type glue outlet head 5, so that the glue in the glue storage cylinder 2 is introduced into the glue storage groove 6 through the pressing type glue outlet head 5, and then discharged from the glue outlet hole 7 to the surface of the roller 1 and absorbed by the sponge sleeve 15. At the same time, the pressing type glue outlet head 5 is used to drive the roller 1 to rotate. Then, the roller 1 and the conveyor belt 14 convey the processed plate. At the same time, the roller 1 and the processed plate squeeze the sponge sleeve 15, so that the glue in the sponge sleeve 15 is applied to the surface of the processed plate, and the glue application work is completed.

[0039] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
