[0025] Embodiment 1

[0026] Please refer to Figures 1-7 , the present utility model provides a technical solution: a dispensing device for electronic component processing, including a processing table 1 and a jig 6. A frame plate 2 is fixedly installed on the side of the processing table 1. A moving plate 3 is arranged at the top of the frame plate 2. A slide rail 4 is fixedly installed on the top of the processing table 1. A placement plate 5 is slidably connected to the surface of the slide rail 4. A chamfer is provided on the surface of the placement plate 5. An electric push rod 7 is fixedly installed on the surface of the moving plate 3. A dispensing head 8 is fixedly installed at the output end of the electric push rod 7. A toothed plate 9 is fixedly installed at the output end of the electric push rod 7. The electric push rod 7 will drive the dispensing head 8 to move downward, and drive the toothed plate 9 to slide downward during this process. Then, under the meshing action, the gear 15 will be driven to rotate. A connecting column 10 is rotatably connected to the bottom end of the moving plate 3. A worm gear 11 is fixedly installed on the surface of the connecting column 10. The worm gear 11 meshes with a worm 14. A connecting plate 12 is fixedly installed at the bottom end of the connecting column 10. A collecting plate 13 is fixedly installed at the top end of the connecting plate 12. The collecting plate 13 is made of stainless steel. A worm 14 is rotatably connected to the bottom end of the moving plate 3. A gear 15 is fixedly installed at one end of the worm 14. The gear 15 meshes with the toothed plate 9. A glue tank 21 is fixedly installed on the top of the moving plate 3. A connecting pipe 22 is communicated with the surface of the glue tank 21. A pressure pump 23 is fixedly installed on the side of the moving plate 3. The liquid suction end of the pressure pump 23 is communicated with the glue tank 21 through the connecting pipe 22. The liquid delivery end of the pressure pump 23 is communicated with the dispensing head 8 through the connecting pipe 22. Start the pressure pump 23 and extract and pressurize the glue inside the glue tank 21 through the connecting pipe 22. Then, under the action of pressure, the glue will be pushed towards the dispensing head 8.

[0027] Embodiment 2

[0028] Please refer to Figures 4-5 , a groove A16 is provided inside the placement plate 5, and a groove B17 is provided inside the jig 6. A limiting piece 18 is rotatably connected to the inside of the groove A16. The number of the limiting pieces 18 is four groups and they are symmetrically distributed inside the placement plate 5. The setting of the four groups of limiting pieces 18 can effectively improve the stability of the jig 6 during the installation process, and it is convenient to disassemble and assemble. A pick-up and placement groove 19 is provided inside the placement plate 5. A handle 20 is fixedly installed on the side of the jig 6. Rotate the limiting piece 18 inside the groove A16 so that it no longer abuts against the surface of the groove B17. Then insert both hands into the pick-up and placement groove 19 and hold the handle 20. Then pull up the handle 20 to remove the jig 6.

[0029] Working principle: When dispensing glue, the electric push rod 7 drives the dispensing head 8 to move downward. During this process, the toothed plate 9 is driven to slide downward. Then, under the meshing action, the gear 15 is driven to rotate, and then the worm 14 is driven to rotate. Under the meshing action of the worm gear 11 and the worm 14, the worm 14 drives the worm gear 11 to rotate by a certain angle, so that the connecting plate 12 and the collecting plate 13 can be moved away from the bottom end of the dispensing head 8. Then, the pressure pump 23 is started, and the glue in the glue tank 21 is pumped out and pressurized through the connecting pipe 22. Then, under the action of the pressure, the glue is pushed towards the dispensing head 8 for dispensing the electronic components. After the dispensing work is completed, the electric push rod 7 drives the dispensing head 8 to rise. Under the action of the toothed plate 9 and the gear 15, the worm 14 is driven to rotate in the reverse direction. Then, under the action of the worm gear 11 and the worm 14, the collecting plate 13 stays at the bottom end of the dispensing head 8 again, so that the residual glue dripping on the surface of the dispensing head 8 can be effectively collected and prevented from dripping onto the electronic components. When it is necessary to replace the fixture 6, first rotate the limiting piece 18 inside the groove A16 so that it no longer abuts against the surface of the groove B17. Then, insert both hands into the picking and placing groove 19 and hold the handle 20. Then, pull up the handle 20 to remove the fixture 6. When installing, first insert the fixture 6 into the inside of the placing plate 5, and then rotate the limiting piece 18 so that it abuts against the surface of the groove B17 again. After all four groups of limiting pieces 18 are adjusted, the installation of the fixture 6 is completed at this time.
