Description

Technical Field

[0001] This application relates to the technical field of punching dies, specifically to a punching die for circuit boards. Background Art

[0002] A circuit board, also known as a printed circuit board or printed wiring board, is an important electronic component. Its main function is to connect various electronic components according to a predetermined circuit to form a complete circuit system and realize various functions of electronic devices. A circuit board usually consists of a substrate made of insulating material, and conductive lines and pads formed through processes such as etching.

[0003] During the production process of circuit boards, stamping operations are required to quickly cut the circuit boards into the required shapes and sizes, improve production efficiency, and at the same time ensure the accurate external dimensions of the circuit boards to meet the design and assembly requirements.

[0004] For example, the patent with the publication number CN217617193U specifically discloses a sheet metal stamping die, including a stamping die, a lower die, a stamping table, a stamping cylinder, a limiting strip, a clamping groove, bolts, and a feeding block. Thus, the sheet metal part can be positioned during the stamping process to ensure stamping accuracy, and by pushing the feeding block, the sheet metal part is sent below the stamping die for stamping.

[0005] When the above-mentioned patent stamping die is in use, one end of the circuit board is passed through the lower part of the pressure plate and placed in the clamping groove of the feeding block, and then the bolts are tightened so that the bolts are in contact with the circuit board. Then the circuit board is pushed to the position for feeding and stamping. Then, the circuit board is pressed tightly on the stamping die by the action of the spring on the pressure plate, and finally punching is carried out. However, in the way of clamping the circuit board by tightening the bolts, the direct contact between the bolts and the circuit board easily causes wear on the surface of the circuit board. At the same time, only by the action of the spring on the pressure plate to press the circuit board tightly, when stamping the circuit board again, the circuit board is prone to deviation. Therefore, it is necessary to design a punching die for circuit boards to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art part is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

Then the circuit board is pushed to the position for feeding and stamping, and the stamping die then punches the circuit board. However, in the way of clamping the circuit board by tightening the bolts, the direct contact between the bolts and the circuit board easily causes wear on the surface of the circuit board.

[0009] Further, a rotating wheel is installed at one end of the screw away from the pressing block.

[0010] Further, an opening groove is formed on one side of the workbench away from the punching assembly. A groove adapted to the size of the lower die is formed on the workbench, and the opening groove is communicated with the groove. A collection assembly is installed on the workbench. The collection assembly includes two groups of slide rails installed on the workbench, and a slider is slidably installed on the slide rails. A collection box is connected between the two sliders.

[0011] Further, two groups of limit plates are installed on the lower die.
