Description

Technical Field

[0001] This utility model belongs to the field of circuit board manufacturing technology, and in particular relates to a circuit board welding positioning fixture. Background Technology

[0002] Circuit boards are the basic components of electronic devices, including substrates, electronic components, copper foil conductors, solder pads, and other structures. Electronic components are fixed to the solder pads by soldering, realizing the electrical connection of electronic components on the substrate.

[0003] Currently, for the production or repair of some circuit boards, electronic components are soldered onto the pads of the substrate by manual soldering. In the production process of manual soldering, the substrate is usually placed on a workbench, and the operator holds the solder wire with one hand and the soldering iron with the other. Therefore, the operator often cannot fix the substrate during soldering, which can easily cause the substrate to wobble and shift, affecting the soldering quality. Utility Model Content

[0004] The purpose of this utility model is to provide a circuit board welding positioning fixture to address the aforementioned technical problems.

[0005] In view of this, the present invention provides a circuit board welding positioning fixture, comprising:

[0006] The base has fixing holes and a first hollow area, and a support plate is provided on the periphery of the first hollow area;

[0007] A cover plate is rotatably mounted on a base, and a second hollow area is provided on the cover plate;

[0008] A flexible limiting component is detachably installed on the second hollow area;

[0009] When the cover plate is placed on the base, the first and second hollow areas are positioned opposite each other, and a positioning area for fixing the circuit board is formed between the support plate and the flexible limiting member.

[0010] Furthermore, the flexible limiting component includes:

[0011] The limiting part is a frame structure and is located within the first hollow area;

[0012] The connecting part is provided with a snap-fit ​​protrusion;

[0013] The cover plate has a slot, and the snap-fit ​​protrusion is adapted to snap into the slot.

[0014] Furthermore, the limiting part is also provided with abutting protrusions, which are used to abut against the circuit board.

[0015] Furthermore, the base also has mounting holes that penetrate through the base.

[0016] Furthermore, it also includes a locking element, which is used to connect and secure the cover plate and the base.

[0017] Furthermore, a fixing groove is provided on the base, and the locking component includes:

[0018] The first magnetic block is mounted on the cover plate;

[0019] The second magnetic block is installed in the fixing slot;

[0020] The first magnetic block is inserted into the fixing slot and is attracted to the second magnetic block.

[0021] Furthermore, there are four fixing holes, which are respectively located at the four corners of the base.

[0022] Furthermore, it also includes a handle, which is mounted on the cover plate.

[0023] The beneficial effects of this utility model are:

[0024] When operators perform circuit board soldering, they place the circuit board in the first cutout area and on the support plate. Then, they rotate the cover plate to place it on the base, and the first and second cutout areas overlap. At the same time, the flexible limiting component installed on the cover plate abuts and presses the circuit board. The flexible limiting component can be made of rubber. The circuit board is clamped and fixed by the support plate and the flexible limiting component, which makes it less prone to displacement. This facilitates the soldering process for operators and makes it highly practical. Attached Figure Description
