Description

Technical Field

[0001] The utility model relates to the technology in the field of jigs, in particular to a pin inserting jig for a PCB board. Background Art

[0002] With the development of technology, electronic products have gradually become one of the indispensable machines in daily work and life. At the same time, the PCB board is one of the indispensable components in electronic products. The Chinese name of the PCB board is printed circuit board, also known as printed wiring board, which is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Since it is made by electronic printing technology, it is called a "printed" circuit board.

[0003] In the production process of the PCB board, the PCB board needs to be inserted with pin feet and then the pin feet are soldered to the PCB board. Currently, the process of inserting pin feet into the PCB board generally adopts an artificial method. When inserting the pin feet, the user needs to find the corresponding position on the PCB board for inserting the pin feet, then insert the pin feet into this position, and then perform the soldering operation. However, the current pin foot assembly efficiency of the PCB board is low. Due to the large number of pin insertions on the PCB board and different pin insertion positions, it is easy for the user to have visual fatigue during the long-term operation of finding the pin insertion positions, resulting in the user being unable to clearly see the PCB board and causing improper soldering and fixing positions of the pin feet on the PCB board. Or, when the user's hand shakes, tin adheres to other positions, which is prone to short circuits, resulting in a high defective rate of the PCB board. As a result, it takes a high time cost to repair defective PCB boards, reducing the production efficiency and product yield of the PCB board, unable to meet the user's usage requirements, and having a small scope of application.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Utility Model

[0005] In view of this, in view of the deficiencies of the existing technology, the main purpose of the utility model is to provide a pin inserting jig for a PCB board, which uses a pin inserting board to press and hold the PCB board in place at the working station, and then controls the pin feet to pass through the pin insertion openings at corresponding positions and be inserted into the PCB board, ensuring the accuracy of the pin insertion positions, facilitating subsequent tin dipping operations. With the setting of the positioning part and positioning holes, it ensures the accurate connection and positioning of the pin inserting board on the base, thereby ensuring the stable and consistent quality of the product, improving the production efficiency of the product, meeting the user's usage requirements, and having a wide scope of application.
