Description

Technical Field

[0001] The present application relates to the field of circuit board repair technology, and in particular to a circuit board bracket. Background Art

[0002] As an important component of electronic products, circuit boards tend to be miniaturized, lightweight, and highly integrated along with the development of electronic products. Miniaturized circuit boards also make their production and maintenance more and more sophisticated. Usually, for small-batch production and maintenance of circuit boards, workers need to operate the circuit boards one by one, so circuit board brackets are needed to limit the circuit boards to facilitate the work of the workers.

[0003] Although the circuit board bracket in the prior art can limit the circuit boards of different sizes by clamping the circuit boards by mounting clips, multiple mounting clips are required to limit the circuit boards by mounting clips. It is cumbersome to adjust multiple mounting clips in order to limit one circuit board. Reducing the number of mounting clips will lead to unstable circuit board limitation. Moreover, clamping the circuit board by mounting clips will cause the clamping area of ​​the circuit board to be more concentrated, so that the circuit board may have clamping marks. Moreover, the circuit board bracket in the prior art cannot limit the position of components when welding components, which will not only cause the welding components to be lost, but also require the position of components to be constantly adjusted during the welding process, resulting in low welding efficiency.

[0004] In summary, the circuit board bracket in the prior art is cumbersome to use during the repair or small-batch production of circuit boards of different sizes, which may cause indentations on the circuit boards, and requires repeated confirmation of the accuracy and tightness of the component positions, resulting in low welding efficiency. Therefore, there is room for further improvement. Summary of the invention

[0005] In view of this, the present application provides a circuit board bracket, which enables workers to easily limit circuit boards of different sizes during small-batch production or circuit board repair, without causing extrusion marks on the circuit boards, and can also effectively and safely limit the positions of components to be soldered, thereby improving the efficiency of workers in small-batch production of circuit boards of different sizes or repairing circuit boards of different sizes.

One end of the circuit board can be fixed in the limiting groove of the first clamp or the third clamp first, and the limiting groove of the third clamp is limited by sliding the third clamp to the other end of the circuit board, so as to achieve the limiting of the circuit board bracket for limiting plates of different sizes, so that the stable limiting of the circuit board can be achieved by sliding the third clamp, which can effectively limit the movement of the circuit board without damaging the circuit board. After the circuit board that has been plugged with components is clamped and fixed, the staff moves and presses the flexible cushion layer to fix it on one end of the circuit board where the components are installed, and fixes the circuit board. The circuit boards are reversed so that the component end face of the circuit board is located at the lower end. At the same time, the flexible pad is also located below the component end face of the circuit board, so that the staff can operate on the non-component end of the circuit board. The flexible pad can quickly limit the components on the circuit board on the one hand, and protect the components from damage on the other hand. When repairing the circuit board, the components on the circuit board can also be limited by the flexible pad, which is convenient for repair and replacement. In this way, the circuit board bracket allows the staff to easily limit the circuit boards of different sizes during the process of small-batch production or repair of circuit boards, without causing extrusion marks on the circuit boards, and can also effectively and safely limit the position of the components to be welded, thereby improving the efficiency of the staff in small-batch production of circuit boards of different sizes or repair of circuit boards of different sizes.
