Secure chip mounter applied to circuit board processing

Abstract

The invention discloses a secure chip mounter applied to circuit board processing. The structure thereof comprises a lateral guide rail, a transfer slot, a lifting motor, a vertical guide rail, a support table and a patch head. A feeder is arranged in the transfer slot. A circuit board is horizontally clamped by the feeder. The lateral guide rail and the vertical guide rail are mechanically connected and in clearance fit. The support table is arranged on the bottom end of the vertical guide rail. The patch head is arranged at the bottom of the support table. According to the invention, the bottom of a hollow tube shaft and a nozzle are fixed together through a vacuum connecting pipe; according to the hollow tube shaft fixed by a supporting claw and a spring shaft, the supporting claw continuously slides down along a lead screw and contacts an opening and closing interface of the hollow tube shaft when a cylinder fails, the vacuum connecting pipe with two convex sides is directly inserted into the opening; once the cylinder fails, an adjacent second cylinder is switched on through the method; and when the nozzle is released to the bottom, the second cylinder is used to drag the nozzle again to prevent the nozzle from falling off.

Description

technical field [0001] The invention relates to the technical field of circuit board processing, in particular to a safe circuit board processing chip placement device. Background technique [0002] The placement machine is needed in the processing of circuit boards. As an important part of the production line, the placement device can automatically correct the position under the control of the correction system after picking up the components through the suction nozzle in the placement head, and Place the circuit board components accurately on the designated position. The installation of the suction nozzle is mainly based on the four claws on the top opening of the suction nozzle. When disassembling, rely on the elasticity and inertia of the spring itself to release the hook of the suction nozzle. , due to the failure of the cylinder, when the suction nozzle is released to the bottom, it cannot hold the suction nozzle, causing the suction nozzle to fall off automatically, f...
