Side wall type plate discharging machine applied to printed circuit board

Abstract

The invention discloses a side wall type plate discharging machine applied to a printed circuit board. The side wall type plate discharging machine applied to the printed circuit board comprises a loading mechanism, a grabbing mechanism, a feeding mechanism, a dust removal mechanism and an electric cabinet; the loading mechanism comprises an 'L'-shaped back plate rack; the back plate rack comprises a rear back plate and a lower supporting plate; the rear back plate is provided with a stopping structure for stopping materials and an insulating plate; the lower supporting plate comprises a plurality of stopping protrusions; the dust removal mechanism comprises first-stage dust blowing structures and second-stage dust adhering structures; each first-stage dust blowing structure comprises a hollow round tube and a first lifting structure; each second-stage dust adhering structure comprises at least two dust adhering rolls, a second lifting structure and hollow rotating shafts which are inserted in the dust adhering rolls; and one end of each hollow rotating shaft is provided with an air suction opening while the other end is provided with a reverse air blowing opening. The side wall type plate discharging machine applied to the printed circuit board can effectively remove foreign matters on the surfaces of plates and in miniature holes, and the integral quality of electronic products is improved; and furthermore, single adsorption of a vacuum sucker can further be realized, the plate discharging machine continuously discharges plates on rollers favorably, and mounting smoothness of a downstream station is ensured.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a side-wall type plate placing machine applied to printed circuit boards. Background technique [0002] At present, in the manufacturing process of PCB (Printed Circuit Board), PCB finished products, PCB semi-finished products or tooling boards need to be transported to the downstream station one by one through the board release machine after completing the upstream work. [0003] The plate releasing machine in the prior art works with the vacuum adsorption system through the manipulator, and absorbs and transports the plates on the inclined plate frame to the rollers one by one. However, during production, the vacuum adsorption system often adsorbs two boards at the same time, which is not conducive to the ability of the board placing machine to continuously place boards on the rollers. [0004] In addition, when the plate is conveyed by the rollers, th...

However, when the sticky dust machine is working, the sticky dust sheet is driven by the transmission device to rotate repeatedly in the circumferential direction. After a long time of use, the effect of the sticky dust sheet will gradually weaken, and it is difficult to remove foreign matter on the surface of the board.
