[0002] A glue dispenser is an automated device that is specifically used to accurately dispense, apply, or spray fluid glue, oil, or other liquid materials onto products. It can be used for a variety of different glues and products. It is widely used in many industries such as electronics, automobiles, medical devices, and handicrafts. For example, it is used for packaging circuit boards and fixing components in the electronics industry; it is used for bonding parts in the automotive industry.

The inner wall of the first slide 140 is threadedly connected to the outer wall of the first screw 120, and a second slide groove 141 is provided on the top of the first slide 140. The inner wall of the second slide groove 141 is rotatably connected to the second screw rod 150 through a bearing, and the second screw rod 150 is driven by a second servo motor 160 installed on the outer wall of the first slide 140.
