Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to a perforation machine for circuit board manufacturing. Background Technology

[0002] In the field of modern electronic equipment manufacturing, circuit boards are the core hub of various electronic products. Their quality and performance directly affect the quality and market competitiveness of the end products. From the early days of electronic computers to today's highly integrated smartphones and artificial intelligence devices, electronic products have been developing rapidly towards miniaturization, high performance, and multi-functionality. This trend has driven circuit boards to evolve towards higher density and higher precision. The manufacturing process of circuit boards is complex and precise, and the through-hole process is a crucial link. The quality of the through-hole not only affects the electrical connection stability of the circuit board, but is also closely related to the product's reliability, service life, and other key performance indicators.

[0003] However, current circuit board fixing devices on the market have design flaws that make it difficult to securely clamp circuit boards. When punching, the circuit boards are prone to displacement or shaking, making it impossible for the drill bit to be accurately positioned. This seriously affects the drilling accuracy and leads to quality problems such as hole diameter deviation and hole position offset. In addition, the fixing devices usually adopt a single structure, which cannot be adapted to the fixing requirements of circuit boards of different sizes. Frequent changes of tooling fixtures are required, which is time-consuming and labor-intensive. To address this, we propose a perforation machine for circuit board manufacturing. Utility Model Content

[0004] The purpose of this utility model is to provide a perforation machine for circuit board manufacturing, in order to solve the problems of the current circuit board fixing device design defects, which make it difficult to firmly clamp the circuit board. When punching, the circuit board is prone to displacement or shaking, making it impossible to accurately position the drill bit, which seriously affects the drilling accuracy and causes quality problems such as hole diameter deviation and hole position offset.

[0024] Working principle of this utility model: This utility model is a perforation machine for circuit board manufacturing. When the perforation machine for circuit board manufacturing is working, firstly, according to the width of the circuit board, the fixing device 4 is fixed in a suitable position by using the fixing ears 402 and locking bolts 403 on the mounting housing 401 to cooperate with the locking holes 7 on the processing table 1. Then, the rocker arm 405 is rotated, which drives the bidirectional screw 404 to rotate, causing the threaded slider 406 to move, which drives the locking plate 407 to adjust its position to match the length of the circuit board. Finally, the rotating block 410 is rotated to adjust... The height of the threaded rod 408 ensures that the stable base 409 makes tight contact with the circuit board, completing the fixation. Then, the rotating motor 502 starts, driving the lead screw 503 to rotate. The connecting block 504 inside the drilling machine body 3 moves on the lead screw 503, allowing the drilling machine body 3 to slide on the top of the fixing frame 2, accurately positioning it according to the drilling position requirements of the circuit board. At the same time, the limiting groove 505 limits and guides the drill rod of the drilling machine body 3, ensuring that the drill rod is vertical and stable. Then, the drilling machine body 3 operates to perform the drilling operation. At this point, the entire process is complete.
