Quick-clamped PCB gluing device

Abstract

The invention discloses a quick-clamped PCB gluing device. The quick-clamped PCB gluing device comprises a frame, a portal, a fixture base, a positioning mechanism, an electromagnet, a cylinder, an upper push plate, a connecting rod, a first spring, a lower push plate, a servo motor, a lead screw, a feeding nut, a slide base and a gluing mechanism; the positioning mechanism further comprises an adjusting mechanism, a slide plate, a limiting rod, an upper limiting plate, a second spring and a lower limiting plate; the electromagnet is powered off; the second spring is returned to push the limiting rod to upwards move to extend outside the fixture base; a PCB to be machined is put in an area consisting of four limiting rods for positioning; the cylinder pushes the upper push plate to downwards move in place, so that the gluing mechanism is contacted with the PCB to be machined; the servo motor drives the gluing mechanism to move; the gluing mechanism glues the surface of the PCB; and after the gluing is finished, the electromagnet is electrified to suck with the lower limiting plate, so that the limiting rods are driven to downwards move to return, and operators can take away the glued PCB.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a fast clamping PCB board gluing device. Background technique [0002] PCB multi-layer board refers to a multi-layer circuit board used in electrical products. Generally, it is a printed circuit board in which single-sided or double-sided boards are alternately connected together through a positioning system and insulating bonding materials, and the conductive patterns are interconnected according to design requirements. Such as four-layer and six-layer printed circuit boards, in the process of making PCB multilayer boards, it is necessary to coat the adhesive glue on the surface of the raw material board. In the existing method, a roller with bristles is often used to directly coat the glue. Since the direction of force bending when the bristles are in contact with the raw material board is uncertain, the glue absorbed on the bristles cannot be evenly coated on the surface of the raw mater...

[0002] PCB multi-layer board refers to a multi-layer circuit board used in electrical products. Generally, it is a printed circuit board in which single-sided or double-sided boards are alternately connected together through a positioning system and insulating bonding materials, and the conductive patterns are interconnected according to design requirements. Such as four-layer and six-layer printed circuit boards, in the process of making PCB multilayer boards, it is necessary to coat the adhesive glue on the surface of the raw material board. In the existing method, a roller with bristles is often used to directly coat the glue. Since the direction of force bending when the bristles are in contact with the raw material board is uncertain, the glue absorbed on the bristles cannot be evenly coated on the surface of the raw material board. When coating, the raw material board is often placed in the fixture with a limit slot, and the push mechanism is used to push the PCB board out when taking the material. The depth of the limit slot is fixed, which cannot meet the coating requirements of PCB boards with different thicknesses. At the same time, push Most of the feeding mechanism is pneumatic, which needs to be equipped with air source, resulting in high equipment cost
