Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing equipment, in particular to a circuit board drilling and loading device. Background Art

[0002] According to the number of layers, circuit boards can be divided into three major categories: single-sided, double-sided, and multi-layer circuit boards. The first is a single-sided board. On the most basic PCB, the parts are concentrated on one side and the wires are concentrated on the other side. Because the wires only appear on one side, this type of PCB is called a single-sided circuit board. Single-sided boards are usually simple to make and low in cost, but the disadvantage is that they cannot be applied to too complex products. Double-sided boards are an extension of single-sided boards. When single-layer wiring cannot meet the needs of electronic products, double-sided boards must be used. Both sides have copper cladding and routing, and the lines between the two layers can be connected through vias to form the required network connection. Multi-layer boards refer to printed boards with more than three layers of conductive graphic layers and insulating materials between them, and the conductive graphics are interconnected as required. Multi-layer circuit boards are the product of the development of electronic information technology towards high speed, multi-function, large capacity, small size, thinness, and light weight.

[0003] After massive searches, it was found that the prior art announcement number is CN 218362270 U, which discloses a circuit board drilling and loading device, including a machine body, a pad and a clamping assembly, the pad is placed on the machine body, the clamping assembly is suitable for clamping the pad on the machine body, the clamping assembly includes a first driving member, a clamping member and a fixed seat, the clamping member includes a rod and a clamping block arranged at one end of the rod, the rod is passed through the fixed seat, and mutually matching guide assemblies are arranged on the inner wall of the fixed seat and the outer wall of the rod, the first driving member drives the rod to rise and fall along its axial direction and passes through the guide assembly to make the rod rotate around its axial direction, and the technical solution provided by the present application solves the technical problem that the pad of the existing circuit board drilling and loading device is inconvenient to replace, which affects the production efficiency and convenience of use.

[0004] Therefore, based on the above search and in combination with the existing ones, during the use of the above scheme, when the wire board is processed and the fixing device is removed, the wire board and the pad may be stuck on the machine, and they need to be manually picked out. In the process of picking, the wire board may pop out due to excessive force, causing unnecessary bumps and the risk of damaging the wire board. A device is needed to separate the wire board and the pad. For this purpose, we propose a circuit board drilling loading device. Utility Model Content

The pad cover piece 4 is used to press the pad tightly to avoid position deviation and damage to the milling cutter during drilling. A pad paddle 9 for pressing the circuit board is arranged on the lower side of the pad cover piece 4. A pulling wire shaft 16 is rotatably mounted on both front and rear ends of the pad cover piece 4.
