There is no structure for fixing the circuit board on the traditional jig, only a groove for the circuit board to be placed. After the printed circuit board is placed in the groove, it is necessary to stick tape around the circuit board to fix the printed circuit board , this kind of jig is cumbersome to operate, and the efficiency of tooling positioning is low
At present, a plurality of pressing plate mechanisms are installed around the jig, and the pressing plate is pressed on the top surface of the printed circuit board by rotating the pressing plate. Although this pressing plate mechanism can improve the tooling positioning efficiency of the printed circuit board, it needs to be rotated. Multiple pressure plates undoubtedly increase the labor intensity of workers and reduce the efficiency of tooling positioning of printed circuit boards

The invention discloses a high-precision jig for tool positioning of a printed circuit board, and the high-precision jig comprises a chassis (1), a left baffle plate (2) and a right baffle plate (3) are respectively welded on the top surface of the chassis (1) and positioned on the left side and the right side of the chassis (1), and a front baffle plate (4) and a rear baffle plate (5) are respectively welded on the top surface of the chassis (1) and positioned at the front end and the rear end of the chassis (1), the front baffle plate (4) and the right baffle plate (3) are provided with a front pressing mechanism and a right pressing mechanism respectively, a closed cavity (15) is formed in the chassis (1), a plurality of inclined holes (16) communicated with the closed cavity (15) are formed in the top surface of the chassis (1), a connector (17) communicated with the closed cavity (15) is further arranged on the side wall of the chassis (1), and the other end of the connector (17) is connected with an air blower (18). The high-precision jig has the beneficial effects that the efficiency of the printed circuit board positioning tool is improved, the working intensity is reduced, and the welding precision is improved.
Description
technical field [0001] The invention relates to the technical field of a jig structure for fixing a printed circuit board, in particular to a high-precision jig for positioning a printed circuit board by a jig and a working method. Background technique [0002] When the printed circuit board is produced, the printed circuit board is usually placed on a carrier first, and then a solder paste layer is applied on the place where the electronic components need to be soldered on the printed circuit board, and then the leads of the electronic components are placed Place the pins on the solder paste, and finally use a soldering machine to solder the pins, so that the electronic components are soldered to the printed circuit board to achieve the fixing effect of the electrical connection. There is no structure for fixing the circuit board on the traditional jig, only a groove for the circuit board to be placed. After the printed circuit board is placed in the groove, it is necessary...
