Technical Field

[0001] The present application relates to the technical field of glue dispensing equipment, for example, to an electromagnet telescopic glue dispensing and clearing mechanism. Background Art

[0002] In various glue dispensing devices, since a large amount of movement of the Z-axis is often not required, large cylinders, electric cylinders and linear drive devices are installed to complete the micro-movement of the Z-axis. The structure is complex, resulting in high costs and inconvenient installation.

[0003] For example, a chip glue sticking device is disclosed in the related art (publication number: CN219642791U), which uses a linear drive mechanism to implement glue sticking, and uses an electric push rod to squeeze out the glue from the injection piston rod. The electric push rod has a high cost and a complex structure.

[0004] A similar related technology (publication number: CN217797071U) discloses a non-stop dual-axis glue dispensing mechanism, which is an X- and Y-axis moving glue dispensing mechanism with a fixed glue head position. The dual-axis movement is achieved through a linear drive device to complete the glue dispensing. This device is large in size and also has a complex structure.
