Description

Technical Field

[0001] The present application relates to the field of circuit board production technology, and in particular to a circuit board double-sided patch welding device. Background Art

[0002] PCB, whose Chinese name is printed circuit board, is also called printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called "printed" circuit board. SMT patch refers to the abbreviation of a series of process flows based on PCB. SMT is surface assembly technology (surface mount technology), which is the most popular technology and process in the electronic assembly industry. Electronic circuit surface assembly technology is called surface mount or surface mounting technology. It is a circuit assembly technology that mounts pinless or short-lead surface assembly components on the surface of printed circuit board PCB or other substrates, and assembles them by welding through reflow soldering or dip soldering.

[0003] When performing patch welding operations, you may encounter circuit boards that require double-sided welding. When welding the patches on the circuit board, after welding one side, you need to take the circuit board out of the fixture, flip it over and fix it again. This process is very time-consuming and will greatly reduce the efficiency of the welding operation. Utility Model Content

[0024] The embodiment of the present application discloses a double-sided patch welding device for a circuit board, including a body 1, the body 1 is provided with a welding gun 2, the body 1 is relatively provided with a support frame 3, the support frame 3 is provided with a mounting block 4, the mounting block 4 is rotatably connected with a fixing plate 5, the fixing plate 5 is provided with a fixing component 6 for fixing the circuit board, the fixing plate 5 is provided with a locking hole 7 on the side wall of the fixing plate 5 close to one of the mounting blocks 4, the mounting block 4 is provided with a locking plate 8, the locking plate 8 is provided with a locking column 9, the locking column 9 is arranged to be plugged into the locking hole 7, and the body 1 is provided with an adjusting component 10 for pulling the locking column 9 out of the locking hole 7.

[0025] When soldering the patch of the circuit board, the circuit board is fixed to the fixed plate 5 by the fixing component 6, and then the locking column 9 is inserted into the locking hole 7 to prevent the fixed plate 5 from rotating. After the circuit board and the fixed plate 5 are fixed, the patch of the circuit board is soldered by the welding gun 2. After the soldering on one side is completed, the locking column 9 is pulled out of the locking hole 7 by the adjusting component 10. At this time, the fixed plate 5 is unlocked, and the fixed plate 5 is rotated and turned over. After the turning over is completed, the locking column 9 is inserted into the locking hole 7 by the adjusting device to fix the fixed plate 5, and then the other side of the circuit board is soldered by the welding gun 2. In this way, the two sides of the fixed plate 5 can be turned over to solder the two sides of the circuit board, without removing the circuit board from the fixed plate 5, turning it over and re-fixing it. The operation is simple and helps to improve the soldering efficiency.

[0026] In one embodiment, the adjustment assembly 10 includes a first telescopic rod 101 and an electric clamp 102 . The first telescopic rod 101 is fixed on the body 1 .

[0031] In one embodiment, the fixing assembly 6 includes a supporting plate 61 and an adjusting bolt 62. The fixing plate 5 is provided with a mounting groove 11. The supporting plate 61 is relatively arranged on the side wall of the mounting groove 11. The fixing plate 5 is provided with an adjusting plate 12. The adjusting bolt 62 is threadedly connected to the adjusting plate 12.

[0032] The circuit board is placed in the mounting groove 11, and then the adjusting bolt 62 is rotated to press the circuit board between the adjusting bolt 62 and the supporting plate 61, thereby fixing the circuit board to prevent the circuit board from being misplaced during welding.
