Description

Technical Field

[0001] The utility model relates to the technical field of PCB board welding, in particular to an auxiliary welding device suitable for a single-sided PCB board. Background Art

[0002] PCB is the abbreviation of printed circuit board (PCB). Usually, the conductive pattern made of printed circuits, printed components or a combination of the two on the insulating material according to a predetermined design is called a printed circuit. The conductive pattern that provides electrical connection between components on the insulating substrate is called a printed circuit. In this way, the finished board of printed circuits or printed circuits is called a printed circuit board, also known as a printed board or printed circuit board.

[0003] PCB circuit boards can be divided into single-sided, double-sided and multi-sided. We usually use single-sided and double-sided boards. Single-sided refers to a single-sided circuit board, with components on one side and wires on the other side. Because single-sided boards have only one side and cannot be crossed, the wiring is more difficult, while double-sided boards can be wired on both sides, with low wiring difficulty, and are more suitable for use in complex circuits. The welding of single-sided boards is usually concentrated on one side, and components are placed on the other side, and single-sided boards only have copper foil on one side.

[0004] When soldering a single-sided PCB, the side with components is usually facing downwards and the other side is facing upwards. Due to the uneven distribution of components under the board, the PCB is not placed flat or is not convenient to place stably. In addition, the single-sided PCB usually needs to be fixed around when soldering. However, single-sided PCBs come in different sizes, and it is difficult to stably fix single-sided PCBs of different sizes. Therefore, there is an urgent need for an auxiliary soldering device that can conveniently and stably fix single-sided PCBs of different sizes. Utility Model Content

Among them, the four short bars 3 are plugged through a four-way connector to form a cross bar.

[0025] In this solution, the auxiliary welding device is first placed on the desktop, and then the welding surface of the single-sided PCB board 15 faces upward, the four movable seats 4 are slid to the positions on the corresponding short rods 3, and then the four side edges of the PCB board 15 are clamped and fixed by the clamping parts on the corresponding sides, so that the PCB board 15 is fixed between the four movable seats 4, and then the welding operation can be performed on the upper surface of the PCB board 15. This solution can adjust the positions of the four movable seats 4 by sliding, and then adjust the positions of the four clamping parts to adapt to the size of the PCB board 15 to be clamped and fixed, so as to facilitate the stable fixing of PCB boards 15 of different sizes.

Each movable seat 4 is sleeved on the corresponding short rod 3 through the guide hole 5 and slides with the corresponding short rod 3. In addition, each short rod 3 is provided with a slide groove 6 along the length direction of the corresponding short rod 3. Each movable seat 4 is provided with a slider 7 which is located in the corresponding slide groove 6 and slides with the slide groove 6. Each movable seat 4 can conveniently move back and forth along the corresponding short rod 3. Since the slider 7 on the movable seat 4 is located in the slide groove 6 on the corresponding short rod 3, the posture of the movable seat 4 is fixed, so that the clamping part on the movable seat 4 is always fixed. For example, the clamping part is located above the movable seat 4, so that the clamping part is convenient for clamping and fixing the PCB board 15.
