Embodiment Construction
[0012] like figure 1 and 2 As shown, a kind of auxiliary fixture for the welding of the platform circuit board includes a base plate 1, a U-shaped support frame 3 is hinged in the middle of the base plate 1, a mounting frame is hinged in the support frame 3, and a sliding rod 5 is mounted on the mounting frame. The sliding rod 5 is threaded with a first jacking screw 4, and a plurality of first guide rods 11 are fixedly connected to the mounting frame. Same as the second jacking wire 7 that fixes the pressing plate 10 to the first guide rod 11 , a flexible top block 9 is connected to the pressing plate 10 .
[0013] After placing the circuit board in the installation frame, use the sliding rod 5 and the first jacking wire 4 to fix the circuit board. When welding, first remove the pressure plate 10, and then solder the SMD electronic components according to the working steps of the circuit board welding. To weld in-line electronic components, first place the SMD electronic co...

Provided are an auxiliary clamp and method for welding a pan-tilt circuit board. The clamp comprises a bottom plate, wherein a U-shaped support frame is hinged to the middle of the bottom plate, a mounting frame is hinged in the support frame, a sliding rod is assembled on the mounting frame, a first jackscrew is connected to the sliding rod in a threaded manner, a plurality of first guide rods are fixedly connected to the mounting frame, a pressing plate is assembled on each first guide rod, the pressing plate is in threaded connection with a plurality of second jackscrews which are used forfixing the pressing plate on the first guide rods, and the pressing plate is connected with a flexible jacking block. The auxiliary clamp and method for welding the pan-tilt circuit board are used forsolving the problems of unstable clamping of an existing circuit board clamp, incapability of overturning the circuit board in the welding process and incapability of fixing in-line electronic components.
Description
technical field [0001] The invention relates to an auxiliary fixture and method for welding a platform circuit board. Background technique [0002] Most of the existing circuit board welding auxiliary clips are fixed clamping type and flexible clamping type. The disadvantages are: the circuit board is clamped by the clamp, and the circuit board is easily scratched during the clamping and welding process, thereby damaging the circuit board; During the welding process, the holding type welding auxiliary clip is often clamped on the side of the circuit board, and the clamping is unstable, which increases the difficulty of welding, and is not suitable for beginners in electronic welding; the flexible holding type welding auxiliary clip is mostly called universal auxiliary clip. Although the clamping of the circuit board can be balanced, when the circuit board needs to be flipped and welded, the circuit board needs to be removed and clamped again, which makes the welding efficien...
