Detailed Description

Embodiments of the present invention will be further described with reference to fig. 1 to 4.

The utility model discloses a concrete embodiment: the automatic jig mainly comprises a support plate 3, a splint strip 2, an upper fixing clamp 5, a lower fixing clamp 7 and a connecting shaft 6, wherein the support plate 3 is provided with air holes 1 and hollow areas 4,

the air holes 1 mainly have the effect that when the embedded capacitor PCB passes through the drying section, hot air can directly reach the board surface through the air holes 1, so that the effect of drying the board edges is facilitated;

the clamping strip bar 2 is mainly used for clamping only the edge of the PCB of the embedded capacitor, and other positions of the PCB which are not clamped can be in full contact reaction with liquid medicine and the like in a production line;

the carrier plate 3 is mainly used for bearing the embedded capacitor PCB in a large area, and indirectly increases the total plate thickness of the embedded capacitor PCB so as to avoid various problems caused by over-thin plate thickness;

the hollow-out area 4 is mainly used for providing convenience when the PCB with the embedded capacitor is turned over up and down, and the position can ensure that fingers or other devices can be better taken;

the upper fixing clamp 5 is mainly used for being vertically matched with the lower fixing clamp 7 to clamp the edge of the embedded capacitor PCB, so that the phenomenon that the PCB is damaged and torn due to direct contact with the ultrathin PCB when the PCB is turned up and down is avoided;

the connecting shaft 6 is mainly used for connecting the batten strip 2, the carrier plate 3, the upper fixing clamp 5 and the lower fixing clamp 7 in series and limiting the moving path of the batten strip 2 and the carrier plate 3 when the PCB is turned over up and down;

the strong magnet 8 mainly acts on different components on the upper and lower surfaces corresponding to the jig in the adsorption equipment, and the strong magnets corresponding to each other on the support plate 3 and the clamp plate strip 2, the upper fixing clamp 5 and the lower fixing clamp 7 provide certain clamping force to prevent the embedded capacitor PCB from sliding out of the protection range of the jig in the conveying process.
