SMT machine with replaceable suction nozzle for anti-deviation

Abstract

The invention discloses an anti-off-tracking chip mounter capable of replacing a suction nozzle. The chip mounter structurally comprises an adhesive dispensing chip mounting head, a conveying roller,a control machine body, a stop dog, an anti-off-tracking rail and a detachable control block, wherein the adhesive dispensing chip mounting head is vertically embedded on the bottom end of the detachable control block; the conveying roller is arranged on the left side of the control machine body; and the bottom end of the stop dog is welded with the top end of the control machine body. By use of the chip mounter, through the improvement of an equipment structure, when the chip mounter is used, whether a component is matched with the suction nozzle and is under a symmetric state or not can be detected through a leveling mechanism on an adsorption head mechanism; if the component and the suction nozzle are under an inclined and asymmetric state, adsorption is not carried out, and therefore,the phenomenon that the production quality of equipment is affected and even the equipment can not be used since the suction nozzle adsorbs and pastes the component is avoided; meanwhile, during dispensing, the chip mounter lowers to trigger an anti-drawing mechanism to be cooperated with a telescopic component; while returning is carried out, pressurization and blowing are carried out on a nozzle, and the breakage speed of the nozzle and glue on a pasting plate is quickened; and therefore, a situation that the quality of the pasting plate is affected due to glue drawing is avoided.

Description

technical field [0001] The invention relates to the field of placement machines, in particular to a placement machine with a deviation-preventing and replaceable suction nozzle. Background technique [0002] The placement machine with replaceable suction nozzle for anti-running is a kind of equipment for mounting components on PCB boards, LED boards and other boards. It has high work efficiency and can carry out placement quickly and effectively. When placing a large number of patches, if the pasting component itself is skewed, and if the suction nozzle continues to absorb at this time, the patch will be absorbed and pasted in a skewed state, which will easily cause defects in the processed product or even fail to be put into use. At the same time, when dispensing pre-mounting, the nozzle nozzle of the dispenser is small, which leads to excessive viscosity of the glue and the adhesion of the nozzle when the glue is returned to the position, causing the glue to be drawn and a...
