Description

Circuit board adhesive deposite device Technical Field The invention relates to the field of circuit board production devices, in particular to a circuit board dispensing device. Background PCB (Printed Circuit Board) dispensing technology is a key technology for fixing and protecting components in an electronic manufacturing process, and dispensing refers to applying glue to a part to be bonded in a dot-like or linear manner at a specific position on a PCB board by using a dispenser. The prior dispensing technology mainly comprises contact dispensing and non-contact dispensing, the front end of a dispensing machine is required to move on a Z axis during contact dispensing, and the non-contact dispensing sprays glue on a PCB workpiece in a manner of extrusion or ultrasonic wave and the like. CN202323327257.1 discloses a dispensing machine for circuit board, comprising a base, a placing groove, a bidirectional threaded rod, a first clamping plate, a second clamping plate, a first motor, a placing platform, a fixing seat, a belt, a second motor and a rotating wheel, wherein the placing platform is arranged on the base, the placing groove is arranged at the position of the base close to the placing platform, the bidirectional threaded rod is arranged in the placing groove, one end of the bidirectional threaded rod is provided with the first motor, one side of the bidirectional threaded rod is provided with a guide rod, two sliding seats are sleeved on the bidirectional threaded rod and the guide rod, the sliding seats are respectively provided with the first clamping plate and the second clamping plate, a positioning block is arranged between the sliding seats, and the two sliding seats are symmetrically arranged relative to the positioning block. After fixing the circuit board on place platform, glue the head through the point and carry out the operation of gluing to the circuit board, but to two-sided circuit board, after the circuit board one side point was glued, still need glue the circuit board another side point, and this kind of point glues the device and glues the back at circuit board one side point, is inconvenient for overturning the circuit board, still need the manual work to take off the circuit board and overturn in order to carry out the point of its another side and glue the work, waste time and energy, be difficult to improve the work efficiency of point and glue the device. The invention is researched and proposed for overcoming the defects of the prior art. Disclosure of Invention The invention aims to overcome the defects of the prior art and provides a circuit board dispensing device.
