Multi-channel and multi-aperture dispensing device

Abstract

The invention discloses a multi-channel and multi-aperture dispensing device which comprises a base. Dispensing needles with various apertures are arranged on the top surface of the base, dispensing heads are integrally mounted at the bottoms of feeding boxes, and a conveying lead screw mechanism is arranged in each feeding box. Conduction valve devices with opposite conduction directions inside and outside are arranged at the communication positions of storage boxes, the dispensing heads and the feeding boxes correspondingly, the feeding boxes are integrally installed on the bottom face of arotary base plate, the multiple feeding boxes are installed on the bottom face of the rotary base plate in a circumferential distribution mode, and a rotary motor is arranged above the rotary base plate. The rotary motor is horizontally arranged at the top of a front panel of a mounting plate through a transverse moving mechanism, and the mounting plate is vertically fixed to the top face of the base. The multiple dispensing heads of different specifications are integrally installed below the rotary base plate capable of moving horizontally, the dispensing heads do not need to be temporarily additionally installed or replaced, the dispensing position is flexibly adjusted, each dispensing head is provided with the corresponding independent feeding box, the feeding boxes can automatically achieve discharging and supplementing actions, mechanical pushing and pressing feeding is achieved, and precision is higher.

Description

technical field [0001] The present invention specifically relates to a dispensing device, in particular to a multi-channel and multi-aperture dispensing device. Background technique [0002] The glue dispenser is mainly used for precise pointing, injecting, coating, and dripping of glue, paint and other liquids in the product process to the precise position of each product, and can be used to achieve dots, lines, circles or arcs. The dispensing machine can be divided into two working methods: manual dispensing: manually use the principle of manual dispensing machine to dispensing glue on electronic products. The principle of the glue dispenser is to use the air pressure to push the glue out within the set time. The time of each injection is controlled by the instrument to ensure that the volume of each injection is the same. As long as the air pressure, time and appropriate needle nozzle are selected, the volume of each injection can be easily changed, which is convenient a...

Problems solved by technology

[0003] At present, the dispensing machines on the market can only be equipped with one standard size dispensing head. When dispensing glue for different products, the dispensing head needs to be manually disassembled, which affects the production process. For multi-head dispensing machines, flexible adjustment and movement cannot be realized. , and multiple dispensing heads share one feeding system, the slow discharge and feeding speed will affect the dispensing speed, the general extrusion method mostly adopts the air pressure extrusion method, and the gas is unstable according to the working environment, which may easily lead to insufficient extrusion accuracy and other problems, therefore, in response to these problems, we need a high-precision dispensing device with multiple feeding channels and multi-aperture dispensing heads
