[0041] Step 1: Upload the required printed circuit board diagram to the computer for further optimization and drawing;

[0048] The molding base 1 has a top plate 2 and a bottom plate 3 horizontally arranged at its upper and lower ends, respectively. Several guide columns 4 are vertically and symmetrically arranged between the top plate 2 and the bottom plate 3 and the molding base 1, and a molding groove 12 is opened through the center of the molding base 1.

[0049] The cutting assembly includes a first movable plate 5 and a second movable plate 6.

The first movable plate 5 and the second movable plate 6 are respectively provided with a stamping module 8 and a lifting module 9 near the forming mold base 1.

[0050] The mounting cavity 11 is located at the lower end of the shaping groove 12 within the shaping mold base 1. A deburring assembly is installed within the mounting cavity 11, comprising an assembly frame 16 and several brush rollers 18. The assembly frame 16 includes two mounting plates and two bearing plates 17. Several second fixing screws are vertically and symmetrically inserted into the upper sides of the shaping mold base 1. These second fixing screws penetrate the upper end of the mounting cavity 11 and are inserted into the upper ends of the two mounting plates. Both bearing plates 17 are annular structures, with the inner ring cross-sectional area of ​​the bearing plate 17 being larger than the cross-sectional area of ​​the shaping groove 12. The two bearing plates 17 are horizontally and symmetrically welded to the upper and lower sides between the two mounting plates. Both bearing plates 17 are vertically and symmetrically connected to the upper and lower sides of the mounting cavity 12. The mold base 1 has several bearing grooves. Several brush rollers 18 are connected to the bearing grooves of two bearing plates 17 through bearings at their upper and lower ends. The upper end of the mold base 1 has a collection groove 13. Several connecting pipes 15 are vertically and symmetrically connected to the side of the collection groove 13 in the mounting cavity 11. Brush bristles are symmetrically arranged on one side of the outer circumference of the brush roller 18. One side of the brush bristles is in contact with the lifting module 9.

The lower ends of several connecting pipes 15 are connected to the upper end of the hollow groove of the brush roller 18 through bearings.

The brush roller 18 passes through the lower end of the bearing plate 17 and is sleeved with a self-rotating gear 20.

[0052] The transmission assembly is inserted into the lower end of the shaping mold base 1 and includes two transmission shafts 26.

The two transmission shafts 26 are inserted into the gear slots through bearings and are fitted with transmission gears 25. The outer ring of the transmission belt 22 has several transmission tooth slots 23 symmetrically opened on one side, and the transmission gears 25 are meshed with the transmission tooth slots 23 on one side.

[0053] The manufacturing method of a 5G base station antenna coupling printed circuit board disclosed in Embodiment 2 of this invention has a structure that is basically the same as that in Embodiment 1. The difference is that the upper end of the lifting module 9 is vertically inserted through the mounting cavity 11 and the shaping groove 12 is set. The upper end of the lifting module 9 through the shaping groove 12 is horizontally provided with the circuit board substrate 10. The cross-sectional areas of the stamping module 8, the lifting module 9, the circuit board substrate 10 and the shaping groove 12 are equal, and the cross-sectional area of ​​the mounting cavity 11 is larger than the cross-sectional area of ​​the shaping groove 12. When cutting the circuit board substrate into independent plates, the cutting is formed in one step with the stamping operation of the lifting module 9 and the stamping module 8. Then, when the two are clamped and driven to move up and down, the brush roller 18 is used to grind and deburr the exposed parts of the circuit board substrate 10. The processing is simple, fast and saves process and equipment costs.

[0054] The manufacturing method of a 5G base station antenna coupling printed circuit board disclosed in Embodiment 3 of the present invention is basically the same as that in Embodiment 2. The difference is that: the upper end of the assembly ring 21 is provided with a slide rail, and the lower end of the transmission belt 22 is provided with a rail groove. The slide rail is inserted into the rail groove of the transmission belt 22. The upper end of the transmission belt 22 is in movable contact with the lower end of the assembly frame 16, so that the transmission belt 22 is limited to a certain extent when it rotates, thereby improving the rotational stability of the transmission belt 22.

[0055] The manufacturing method of a 5G base station antenna coupling printed circuit board disclosed in Embodiment 4 of the present invention is basically the same as that in Embodiment 3. The difference is that: the upper end of the base plate 3 is provided with an auxiliary shaft on one side of the two drive shafts 26. The two drive shafts 26 are both cylindrical structures, and the two drive shafts 26 are respectively movably sleeved with the two auxiliary shafts, so that the auxiliary drive shafts 26 can rotate stably.

[0056] The manufacturing method of a 5G base station antenna coupling printed circuit board disclosed in Embodiment 5 of the present invention is basically the same as that in Embodiment 4, except that: the second movable plate 6 has vertical through-holes on both sides, and the two through-holes are respectively movably sleeved with two transmission shafts 26. The outer circumference of the two transmission shafts 26 is provided with a spiral groove 27 on one side, and a sliding block 28 is horizontally provided on one side of the through-hole. The two sliding blocks 28 are respectively movably inserted into the spiral grooves 27 of the two transmission shafts 26. When the second movable plate 6 moves vertically up and down, it drives the two transmission shafts 26 to rotate, thereby driving the transmission gear 25 and the transmission belt 22 to rotate. Then, several rotating gears 20 drive the brush roller 18 to rotate, and brush off the burrs on the edges and corners of the circuit board substrate 10.

[0057] In use, the required printed circuit board circuit diagram is uploaded to the computer for further optimization and drawing. A suitable circuit board substrate is selected, and it is cut into independent units of the corresponding size by a high-efficiency multi-functional punching device. During the cutting process, the substrate is laid flat on the upper end of the shaping mold base 1. The existing technology collection and conveying device can be used for continuous movement operation. Two telescopic cylinders 7 are activated to control the up and down movement of the punching module 8 and the lifting module 9. In conjunction with the shaping groove 12 of the shaping mold base 1, the circuit board substrate 10 is quickly cut. After the cutting is completed, it is pushed down further, while maintaining the stable clamping of the circuit board substrate 10 by the punching module 8 and the lifting module 9. During the downward movement, the sliding block 28 set on the second movable plate 6 slides relative to the spiral groove 27 of the transmission shaft 26. The transmission shaft 26 drives the transmission gear 25 to rotate, and the two transmission gears 25 rotate in the same direction. Then, the transmission belt 22 rotates parallel along the slide rail under the meshing action of the transmission tooth groove 23. The rotating gears 20 and brush rollers 18 drive the rotation of the circuit board substrate 10 to polish and remove the edges and corners. Since the number of rotations of the transmission gear 25 is limited, the circuit board substrate 10 needs to move up and down reciprocally under the action of the stamping module 8 and the lifting module 9. The efficiency of the movement depends on the requirements. The diameter of the transmission gear 25 is much larger than that of the rotating gear 20. After cleaning, the lifting module 9 returns to its original position, and the upper surface is flush with the shaping mold base 1. The circuit board substrate 10 is then removed, and the next circuit board substrate 10 can be quickly cut in the same way. The overall device is simple and convenient to operate, install, and maintain. The edges and corners are polished and deburred. The cut substrate units are glued on both sides and punched. After punching, the glue is removed to avoid burrs in the holes. The substrate is then cleaned and then ink is applied. After ink application, the ink is dried. The image is printed and silver paste is applied across the lines and cured. After sampling and power-on testing, the substrate is packaged and stored.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
