Embodiment Construction

[0027] In order to further illustrate the glue dispenser needle, glue dispenser and glue dispensing method provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.

[0028] see figure 1 and figure 2 The dispensing machine needle 10 provided by the embodiment of the present invention includes a needle body 11 and a sensing device. The sensing device includes an elastic element 12 connected to the edge of the glue inlet at one end, and a signal processor connected to the elastic element 12. The elastic element 12 The free end of the dispenser needle 10 extends along the glue outlet direction and exceeds the glue outlet; the signal processor is used to generate a deformation signal according to the deformation of the elastic element 12 .

[0029] For an example, please continue to figure 1 and figure 2 , the dispenser needle 10 provided by the embodiment of the present invention includes a...

Abstract

The invention discloses a needle head of a dispensing machine, a dispensing machine and a dispensing method and relates to the technical field of dispensing equipment. The problem that a needle head of a dispensing machine and a product to be dispensed are easy to damage during the dispensing process is solved. The needle head of the dispensing machine comprises a needle head main-body, a glue inlet and a glue outlet positioned on the needle head main-body, and a sensing device. The sensing device comprises an elastic component with one end connected at the edge of the glue inlet, and a signal processor which is connected to the elastic component. A free end of the elastic component extends along the glue exudation direction of the dispensing machine's needle head to go beyond the glue outlet. The signal processor generates deformation signals according to deformation quantity of the elastic component. When the needle head of the dispensing machine collides with the product to be dispensed, the elastic component firstly collides with the product to be dispensed, a deformation signal generated by the signal processor changes, and then the needle head of the dispensing machine stops running so as to prevent the damage to the needle head of the dispensing machine and the product to be dispensed. The dispensing machine provided by the invention is used for dispensing a product to be dispensed after the product is installed on the dispensing machine.

Description

technical field [0001] The invention relates to the technical field of dispensing equipment, in particular to a needle of a dispensing machine, a dispensing machine and a dispensing method. Background technique [0002] A glue dispenser is a device that uses air pressure to apply glue on the surface or inside of a product within a set period of time. It is widely used in the electronics industry, such as LCD (Liquid Crystal Display, liquid crystal display) sealing glue, IC (Integrated Circuit, integrated circuit) packaging, IC bonding, PCB (Printed Circuit Board, printed circuit board) bonding sealant, circuit components and substrate bonding. [0003] The dispensing machine usually includes a dispensing machine needle, which is usually a plastic product. During the dispensing process, a certain distance should be kept between the dispensing machine needle and the product to be dispensed. When the product collides, the needle of the dispensing machine for plastic products i...
