[0028] In the technical solution of the present utility model, the glue in the glue storage tube 21 falls onto the workpiece a on the dispensing station 31 through the valve port of the screw valve 22. The screw valve 22 can very precisely control the flow rate and ejection amount of the glue, so as to ensure that the precise amount of glue drops to reach the precise thickness coating, and can quickly stop the glue when needed, avoiding glue dripping or overflowing, which can effectively improve the dispensing response speed and control accuracy of the dispensing device 1000, enabling the dispensing device 1000 to be applied to production lines with high-precision requirements or high-speed operation, and realizing the expansion of the application range of the dispensing device 1000.

[0029] In an embodiment, the dispensing device 1000 further includes a conveyor line 3. The conveyor line 3 is arranged on the frame 1. The conveyor line 3 has a dispensing station 31. The conveyor line 3 is used to convey the workpiece a to be dispensed to the dispensing station 31.

[0030] In an embodiment, the dispensing mechanism further includes an infrared sensor 23. The infrared sensor 23 is arranged on the screw valve 22 and faces the dispensing station 31. The infrared sensor 23 is electrically connected to the conveyor line 3. When the workpiece a to be dispensed on the conveyor line 3 is conveyed by the conveyor line 3 to the dispensing station 31, the infrared sensor 23 senses the workpiece a to be dispensed and then uploads a signal to the dispensing device 1000. The industrial control computer in the dispensing device 1000 controls the conveyor line 3 to stop running, and the workpiece a to be dispensed stays on the dispensing station 31 waiting for the dispensing mechanism to dispense glue; thus realizing the automatic control of the conveyor line 3 and saving labor costs.

[0031] In an embodiment, the infrared sensor 23 is electrically connected to the screw valve 22. When the workpiece a to be dispensed on the conveyor line 3 is conveyed by the conveyor line 3 to the dispensing station 31, the infrared sensor 23 senses the workpiece a to be dispensed and then uploads a signal to the dispensing device 1000. The industrial control computer in the dispensing device 1000 controls the screw valve 22 to open, realizing automatic dispensing.

[0032] In one embodiment, the dispensing mechanism further includes a moving module disposed on the frame 1, and the screw valve 22 is connected to the output end of the moving module. The moving module controls the movement of the screw valve 22, so as to be able to perform dispensing operations such as dotting, line drawing, drawing circles or arcs on the workpiece a.

The conveying line 3 further has an assembling station 32, and the assembling station 32 is located at a position behind the dispensing station 31 along the conveying direction of the conveying line 3; the assembling module includes a moving component and an assembling platform 42. The assembling platform 42 is disposed on the frame 1 and is used for placing the product b to be assembled; the moving component is disposed on the frame 1 and is used for moving the workpiece a on the assembling station 32 to the assembling platform 42. After the dispensing is completed, the workpiece a is moved by the moving component to the assembling platform 42 to be assembled with the product b to be assembled.

[0035] It can be understood that the moving component can be a manipulator or can be composed of a slide rail and a slider. In one embodiment, the moving component includes a second longitudinal slide rail 411, a second longitudinal slider 412, and a suction plate 413.

In this way, the workpiece a after dispensing is sucked by the suction plate 413 and moved from the assembling station 32 on the conveying line 3 to the assembling platform 42 for the next assembling work.

[0036] The assembling platform 42 has a plurality of installation stations 421 circumferentially distributed along the axis of the assembling platform 42. In one embodiment, the assembling platform 42 is rotatably connected to the frame 1; the assembling platform 42 has eight installation stations 421 circumferentially distributed along the axis of the assembling platform 42, and the installation stations 421 are used for placing the product b to be assembled; the moving component is used for moving the workpiece a on the assembling station 32 to the installation station 421.
