Background technique

Electronic component assemblies include single-sided circuit boards, double-sided circuit boards, flexible boards, multi-layer printed circuit boards, etc. These electronic component assemblies are the core components of the controller and can play an important role. The circuit board is processed through a series of processes such as etching, exposure, and silk screen printing. Among them, the high-speed printed circuit board has the technical characteristics of faster transmission frequency than the ordinary circuit board. The structure of the high-speed printed circuit board is shown in Figure 1. The process requires that the stop 26 be processed on the left and right outer end faces of the high-speed printed circuit board, and the bottom surface of the stop 26 is required to be a horizontal surface, and the horizontal surface is used as the mounting surface of the chip, so that the chip is hidden, so that the entire high-speed printing The circuit board is installed in a narrower space; it is also required to process a plurality of through holes 27 on the bottom surface of the stop 26, and the through holes 27 are used as heat dissipation holes or wire holes. Schematic diagram of the structure of the printed circuit board.

The existing method and steps of using a high-speed printed circuit board to process a finished high-speed printed circuit board are as follows: the worker first fixes the high-speed printed circuit board to be processed on the tooling table of the milling machine through the pressing plate clamping mechanism, and then operates the milling machine to make the high-speed printed circuit board. The milling cutter of the milling machine moves along the width direction of the high-speed printed circuit board. After the milling cutter passes through the circuit board, the two outer end faces of the high-speed printed circuit board can be machined to form the stop 26, and then the worker opens the Press plate clamping mechanism to remove the semi-finished high-speed printed circuit board from the tooling table, after removal, fix the semi-finished high-speed printed circuit board tooling to the positioning table of the drilling machine, and the worker operates the drilling machine to make the drill bit in the drilling machine A plurality of through holes 27 are drilled on the bottom surface of the stop 26 to finally produce a product.

However, although the existing processing method can process products with a stop, after mass production of a batch of products, the technicians found the following technical defects:

1. The bottom surface of the stop 26 of the product is not a horizontal plane, but an inclined plane 28. As shown in Figure 4 to Figure 5, it is the structural schematic diagram of the product actually processed, thereby greatly reducing the production quality of the product. The stop 26 needs to be calibrated, which undoubtedly increases the production process and greatly reduces the production efficiency of the product.

II. In the process of processing the stop 26, the high-speed printed circuit board needs to be positioned on the tooling table of the milling machine first. After processing the stop 26, the high-speed printed circuit board needs to be transferred to the positioning table of the drilling machine. , and make it a positioning tooling. There will undoubtedly be a positioning error through the two positioning tooling, which greatly reduces the positional accuracy of the through hole 27, that is, the position of the through hole 27 on the bottom surface of the stop 26 does not meet the requirements. The production quality of the product is reduced, and there is a technical defect of low production precision.

III. After the stop 26 is processed on the high-speed printed circuit board, it needs to be transferred to the drilling station, and the high-speed printed circuit board needs to be clamped twice, which undoubtedly increases the production cycle, and furthermore Greatly reduces the production efficiency of the product.

For the forming of the semi-finished high-speed printed circuit board, the worker first controls the drive motor (22) to start, the drive motor (22) drives the milling cutter (19) to rotate, and then the worker controls the hydraulic slides ( 21) At the same time, the hydraulic slide table (21) drives the moving table (23) to move forward, and the moving table (23) drives the driving motor (22) and the milling cutter (19) to move forward synchronously, and the milling cutter (19) is rotated at this time. ) is attached to the top surface of the clamping block (8) to gradually mill the material on the outer end face of the high-speed printed circuit board (25) from back to front. When the milling cutter (19) passes through the high-speed printed circuit board (25), the Outlets (26) are formed on the left and right outer end faces of the printed circuit board (25); S6. For the forming of the finished high-speed printed circuit board, the worker controls each servo motor (13) to start, the servo motor (13) drives the drill bit (14) to rotate, and then the worker controls the piston rod of each lift cylinder (12) to extend upward, and the piston The rod drives the servo motor (13) to move upward, the drill bit (14) passes through the through slot (11) and drills a number of required through holes (27) on the bottom surface of the stop (26), thereby finally producing the finished product at high speed. printed circuit boards; S7 , repeating the operations of steps S2 to S6 , a plurality of finished high-speed printed circuit boards can be produced in batches continuously.
