Description

Technical Field

[0001] The utility model relates to the field of glue dispensing equipment, in particular to a glue cleaning device for a glue dispensing needle. Background Art

[0002] With the development of science and technology, electronic products are becoming thinner and lighter, and their precision is also getting higher and higher. Automatic dispensing machine is an automated equipment developed for the packaging industry. It realizes product packaging by controlling the colloid to drip or apply it on the workpiece product. It is also called glue machine or glue coating machine. Since automatic dispensing machine can effectively reduce the demand for human resources, the phenomenon of manpower shortage can be alleviated to a certain extent.

[0003] After the glue dispensing head dispensing glue, there is usually residual glue, which will not only affect the next glue dispensing, but also the residual glue can easily scratch the surface of the product. Therefore, the glue dispensing device is often equipped with an automatic glue cleaning mechanism to automatically clean the glue dispensing head instead of manual cleaning, thereby improving the cleaning efficiency. For example, the prior art Chinese utility model patent CN211660325U discloses a glue dispensing head glue cleaning device, which includes a fixed seat, a motor and a soft glue cleaning head. The motor is installed on the fixed seat, and the soft glue cleaning head is coupled to the motor and driven to rotate by the motor to clean the glue dispensing head of the glue dispensing machine.

[0004] When the above-mentioned prior art is applied, since the needle is generally only 0.1 to 1 mm, and the glue cleaning head used to clean the glue dispensing head is driven by a motor, the rotation speed of the motor is difficult to control during rotation, which causes the glue cleaning head to easily damage the needle; and the needle is only wiped by the rotating glue cleaning head, which is prone to wire drawing and cannot be wiped clean. Residual glue is easily stuck to the glue cleaning head, resulting in incomplete cleaning of the needle, thereby affecting subsequent glue dispensing. Utility Model Content
