Description

Technical Field

[0001] The invention relates to the technical field of glue dispensing, and in particular to a glue dispensing device for a radiator. Background Art

[0002] With the development of technology, integrated circuits are increasingly used in various electronic devices. For example, integrated circuits are widely used in computers. Heat is generated during the operation of the integrated circuit. If it is not discharged in time, the temperature of the integrated circuit will rise rapidly, resulting in unstable system operation, shortened service life, and even possible burning of some components. The radiator is used to absorb the heat generated by the integrated circuit and then dissipate it into or outside the chassis to ensure that the temperature of the components of the electronic equipment is normal. In the assembly and production of the radiator, a dispensing machine is needed to apply solder paste to the solder paste holes in the heat dissipation block of the radiator to facilitate the positioning of the copper tube and plugging it into the solder paste hole. The operating mode of the glue dispensing machine currently used on the production line is as follows: pour glue into the syringe, the operator holds the workpiece to be glued in his left hand, holds the glue barrel filled with solder paste in his right hand, aligns it with the position to be glued, and dispenses glue according to the glue dispensing trajectory; use the foot to control the start and stop of the glue dispensing machine, step on the foot, the NO end (normally open end) of the foot switch is closed, and the glue dispensing machine starts working; when the foot is released, the NO end (normally open end) is disconnected, the NC end (normally closed end) is closed, and the glue dispensing machine stops working.
