Adopting the above process can not only solve the problems that the glass is easily broken when the vacuum sputtering and electroplated copper foil are thickened, it is easy to cause scratches during the etching of the circuit, and the bonding force of the sputtering electroplating copper is relatively low, but also can realize mass production after adopting the above process, and the bonding force can be ensured to be stable through the adhesive bonding of the adhesive solution, effectively improving the practicability.

[0045] Example 3

[0046] Based on the above Example 2, as Figures 2 - 6 shown, the mixer includes a U-shaped base 6. A plurality of support rods 5 are fixedly arranged at the lower end of the U-shaped base 6. Two symmetrically arranged support blocks 16 are arranged inside the U-shaped base 6. A support ring 10 is fixedly arranged on the support block 16. A mixing tank 8 is rotatably connected inside the support ring 10. The mixing tank 8 is provided with an inlet and outlet. A baffle 9 is detachably installed at the inlet and outlet. A driving component is also installed inside the U-shaped base 6, and the driving component is used to drive the mixing tank 8 to rotate.

[0047] Among them, preferably, the driving component includes a driving motor 15 and an external tooth ring 11. The external tooth ring 11 is fixedly installed on the mixing tank 8. The driving motor 15 is fixedly installed on the lower inner wall of the U-shaped base 6. The right output end of the driving motor 15 is fixedly connected to a rotating rod 14. The right end of the rotating rod 14 is rotatably connected to the right vertical section of the U-shaped base 6. A first gear 13 is fixedly arranged on the rotating rod 14. The upper side of the first gear 13 is meshed and connected with the external tooth ring 11.

[0048] Among them, preferably, two stirring rods 12 are arranged up and down in the mixing tank 8. The stirring rods 12 are rotatably connected to the mixing tank 8. The upper stirring rod 12 extends out of the mixing tank 8 to the right, and the upper stirring rod 12 is rotatably connected to the extended position of the mixing tank 8. The lower stirring rod 12 extends out of the mixing tank 8 to the left, and the lower stirring rod 12 is rotatably connected to the extended position of the mixing tank 8. The upper stirring rod 12 and the lower stirring rod 12 are centrosymmetric about the center point of the mixing tank 8. A plurality of stirring blades 24 are also fixedly arranged on the stirring rods 12. One end of the stirring rod 12 far away from the mixing tank 8 is fixedly connected to a second gear 25. Incomplete internal tooth rings 7 are fixedly installed on the mutually close sides of the vertical sections of the U-shaped base 6. The second gear 25 is matched with the incomplete internal tooth ring 7.

[0049] The working principle and beneficial effects of the above technical solution are as follows: Open the baffle 9, put bisphenol A resin, high-viscosity resin, isocyanate, antioxidant, accelerator, UV stabilizer and UV absorber into the mixer in proportion, start the drive motor 15, the rotating rod 14 starts to rotate, the rotating rod 14 drives the first gear 13 to rotate, the first gear 13 drives the external gear ring 11 to rotate, and the external gear ring 11 drives the mixing tank 8 to rotate. Since the stirring rods 12 are arranged in two parts, upper and lower, that is, the stirring rods 12 are in an eccentric position, the mixing tank 8 will drive the stirring rods 12 to move around the center points on the left and right sides of the mixing tank 8. The stirring rods 12 drive the second gears 25 to move around the center points on the left and right sides of the mixing tank 8. At this time, the second gears 25 cooperate with the internal gear ring 7. During the movement of the second gears 25, the second gears 25 will rotate, so that the stirring rods 12 start to rotate. The stirring rods 12 drive the stirring blades 24 to rotate, and the stirring blades 24 stir the liquid in the mixing tank 8. At this time, if the mixing tank 8 rotates forward, then the stirring rods 12 rotate backward. If the mixing tank 8 rotates backward, then the stirring rods 12 will rotate forward, that is, the rotation direction of the mixing tank 8 is opposite to the rotation direction of the stirring rods 12, so that the liquid in the mixing tank 8 can be better mixed and dispersed, effectively improving the mixing effect and effectively improving the convenience and practicality.

[0050] Example 4

[0051] On the basis of the above Examples 2-3, as Figures 2 - 6 shown, the mixing tank 8 includes an inner tank and an outer tank. There is a coolant between the inner tank and the outer tank. A hollow rod 22 is arranged in the mixing tank 8. The hollow rod 22 is fixedly connected to the inner walls on the left and right sides of the inner tank. Two symmetric piston blocks 21 are arranged in the hollow rod 22. A wire harness 18 is fixedly installed on the side of the piston block 21 away from each other. The wire harness 18 extends out of the mixing tank 8, and the wire harness 18 is slidably connected to the extended position of the mixing tank 8. A spring 23 is also fixedly installed on the side of the piston block 21 away from each other. The other end of the spring 23 is fixedly connected to the inner tank. The spring 23 is sleeved on the wire harness 18; Two symmetric communication components are arranged on the left and right sides of the hollow rod 22. The communication components include two symmetric communication pipes 33 up and down. One end of the communication pipe 33 is connected to the hollow rod 22 in a penetrating manner. Four holes are opened on the inner tank. The four holes are symmetrically arranged in pairs. The communication pipe 33 is fixedly connected to the holes in a penetrating manner;

[0052] Fixed pulleys 19 are symmetrically installed on the left and right sides of the mixing tank 8. A wire wheel 20 is fixedly installed on the stirring rod 12. The wire harness 18 bypasses the fixed pulley 19, and the other end of the wire harness 18 is fixedly wound around the wire wheel 20.

[0053] Among them, preferably, a first discharge pipe 26 penetrates through the mixing tank 8, a first valve 28 is provided on the first discharge pipe 26, a through hole is opened on the vertical section of the U-shaped base 6, a second discharge pipe 27 is installed in the through hole, a second valve 30 is provided on the second discharge pipe 27, a corrugated pipe 31 is installed at the upper end of the second discharge pipe 27, and a clamp 32 is installed on the corrugated pipe 31. The clamp 32 is used to connect the first discharge pipe 26 and the corrugated pipe 31. A filter screen 29 is also provided in the second discharge pipe 27; a water outlet 17 is also provided on the mixing tank 8.

[0054] Among them, the filter screen 29 is a 5-10 micron filter screen.

[0055] The working principle and beneficial effects of the above technical solution are as follows: When the second gear 25 meshes with some internal teeth inside the incomplete internal gear ring 7, the second gear 25 will drive the stirring rod 12 to rotate. The stirring rod 12 drives the connecting pipe 33 to rotate, and the connecting pipe 33 drives the wire harness 18 to wind around the connecting pipe 33. When the wire harness 18 moves, the wire harness 18 pulls the piston block 21, and the two piston blocks 21 move in opposite directions, the spring 23 is compressed, and the piston block 21 pushes the coolant in the hollow rod 22 into the space between the inner tank and the outer tank through the connecting pipe 33, thus causing the flow of the coolant.

[0056] When the second gear 25 does not mesh with some internal teeth inside the incomplete internal gear ring 7, under the action of the spring 23, the piston blocks 21 move towards each other, the wire harness 18 pulls the connecting pipe 33 to make the connecting pipe 33 rotate, and the connecting pipe 33 drives the stirring rod 12 to rotate and reset. Thus, the stirring rod 12 can rotate in two directions, making the stirring effect better. When the piston blocks 21 move towards each other, the coolant between the inner tank and the outer tank will flow back into the hollow rod 22, thus causing the coolant to keep flowing continuously, effectively avoiding overheating during the mixing and dispersion process, and having a better cooling effect. The structure is simple, easy to use, and can effectively improve the practicability and convenience of the device.

[0057] After the mixing is completed, stretch the corrugated pipe 31 upward, sleeve and fix the corrugated pipe 31 outside the first discharge pipe 26 through the clamp 32, open the first valve 28 and the second valve 30 on the second discharge pipe 27, and the mixed glue 2 flows out of the mixing tank 8, passes through the first discharge pipe 26 and the corrugated pipe 31, and then passes through the filtration of the filter screen 29 and flows out from the second discharge pipe 27 (at this time, the outlet end of the second discharge pipe 27 can be connected to a coater).

[0058] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. If these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
