[0027] Please see Figure 4 A dispensing machine nozzle positioning assembly includes a support plate 1. Support columns 2 are fixedly connected to the four corners of the top of the support plate 1. Support members 3 are fixedly connected between the tops of the four support columns 2. A movable channel is opened at the top of the support member 3. A movable slider 4 is slidably connected inside the movable channel. A push channel is opened at one end of the movable slider 4. A push slider 5 is slidably connected inside the push channel. A dispensing syringe 6 is fixedly installed at one end of the push slider 5. A dispensing nozzle 7 is fixedly installed at the bottom end of the dispensing syringe 6. A delivery hose 8 is fixedly installed at one end of the dispensing syringe 6. An electric push rod 9 is fixedly installed at the top of the movable slider 4. The bottom end of the electric push rod 9 extends into the movable channel and is fixedly connected to the top of the movable slider 4. When the electric push rod 9 is activated, the position of the push slider 5 is moved by the electric push rod, which in turn moves the dispensing position of the dispensing syringe 6 and the dispensing nozzle 7 up and down.

[0028] Please see Figure 2 , Figure 3 , Figure 5 and Figure 7The top of the support plate 1 has a connecting slot, and the bottom of the support plate 1 is fixedly connected to two mounting parts 10. One end of one mounting part 10 is fixedly connected to a first motor 11, and the output end of the first motor 11 is fixedly connected to a rotating screw 12. The other end of the rotating screw 12 extends into the interior of the connecting slot and is rotatably connected to one end inside the connecting slot. A rotating sleeve 13 is screwed onto the outer wall of the rotating screw 12. The top of the rotating sleeve 13 is fixedly connected to a placement plate 14. The top of the placement plate 14 is fixedly installed with a dispensing part positioning and clamping mechanism, which includes a second motor 16. The top of the placement plate 14 has two clamping grooves, and one end of each clamping groove has a clamping through hole. Both clamping through holes are rotatably connected to a bidirectional screw 17. Two clamping sleeves 18 are screwed onto the outer wall of the screw 17. A clamping plate 19 is fixedly connected between the two clamping sleeves 18. One end of the second motor 16 is fixedly connected to one end of the placement plate 14. The output end of the second motor 16 is fixedly connected to one end of one of the bidirectional screws 17. Pulleys 20 are fixedly connected to the outer walls of both bidirectional screws 17. A transmission belt 21 is connected between the two pulleys 20. After the dispensing workpiece is placed on the top of the placement plate 14, the output end of the second motor 16 will drive the bidirectional screw 17 to rotate, and drive the two clamping sleeves 18 to move through the threads, and drive the clamping plates 19 to move closer to each other, thus completing the positioning and clamping of the dispensing workpiece. Meanwhile, after the first motor 11 is powered on... The output end of the first motor 11 will drive the rotating screw 12 to rotate, and drive the rotating sleeve 13 to move through the thread. The movement of the rotating sleeve 13 will drive the position of the placement plate 14 to move, thereby realizing the movement of the dispensing position of the dispensing workpiece before and after dispensing.

[0029] Please see Figure 1 and Figure 6An extension plate 15 is fixedly connected to one end of the movable slider 4. A reciprocating positioning and pushing mechanism is fixedly installed at one end of the extension plate 15. The reciprocating positioning and pushing mechanism includes an adjusting plate 22. Four adjusting rods 23 are fixedly connected to the top of the adjusting plate 22. Adjusting components 24 are fixedly connected to the top of each of the two adjusting rods 23. A load-bearing plate 33 is fixedly connected between the two adjusting components 24. One end of the load-bearing plate 33 is fixedly connected to one end of the support component 3. Adjusting through holes are opened at the top of each of the two adjusting through holes. Rotating shafts 25 are rotatably connected inside each of the two adjusting through holes. Incomplete gears 26 are fixedly connected to the top of each of the two rotating shafts 25. Transmission racks 27 are fixedly installed at both ends of the extension plate 15. The two incomplete gears 26 mesh with the transmission racks 27 respectively. A third motor 28 is fixedly connected to the bottom end of the adjusting plate 22. The output end of the third motor 28 extends to the top of the adjusting plate 22. Rotating gears are fixedly connected to the output end of the third motor 28 and the outer wall of the bottom end of the two rotating shafts 25. 29. Three rotating gears 29 mesh with each other. When the third motor 28 is powered on, the two rotating shafts 25 are driven to rotate through the meshing of the rotating gears 29. The two rotating shafts 25 rotate in opposite directions, which drives the two incomplete gears 26 to rotate. When one of the incomplete gears 26 meshes with the transmission rack 27, the other incomplete gear 26 will not mesh with the transmission rack 27. One of the incomplete gears 26 will drive the extension plate 15 and the movable slider 4 to move through the meshing. After one of the incomplete gears 26 is no longer meshing with the transmission rack 27, the other incomplete gear 26 will contact the transmission rack 27 and drive the extension plate 15 and the movable slider 4 to move in the opposite direction. This completes the left and right movement of the dispensing syringe 6 and the position movement and positioning of the dispensing nozzle 7. The dispensing syringe 6 and dispensing nozzle 7 in this device are existing technologies and are used in common dispensing machines. The glue is delivered through the delivery hose 8.

[0030] It should also be noted that four stable feet 30 are fixedly connected to the bottom ends of the support plate 1 and the adjustment plate 22 to support the position of the overall device and increase the height of the overall device. Two limiting sliders 31 are fixedly connected to the bottom end of the placement plate 14. The bottom ends of the two limiting sliders 31 are slidably connected to the top end of the support plate 1. When the placement plate 14 is moved by rotating the screw sleeve 13, it will move above the top end of the support plate 1 through the limiting sliders 31, which will improve the stability of the placement plate 14 when it moves. A limiting slider 32 is fixedly connected to the bottom end of the extension plate 15. The bottom end of the limiting slider 32 is slidably connected to the top end of the load-bearing plate 33. When the extension plate 15 moves left and right, it will move above the load-bearing plate 33 through the limiting slider 32, which will improve the stability of the extension plate 15 when it moves.

[0031] In summary, when using this dispensing machine nozzle positioning assembly, the dispensing workpiece is first placed on the top of the placement plate 14. Then, the second motor 16 is energized, causing its output to drive the bidirectional screw 17 to rotate. This screw, through its thread, moves the two clamping sleeves 18, causing the clamping plates 19 to move closer together, thus positioning and clamping the dispensing workpiece. Next, the first motor 11 is energized, causing its output to drive the rotating screw 12 to rotate. This rotating screw, through its thread, moves the rotating sleeve 13, causing the placement plate 14 to move, thereby moving the dispensing workpiece back and forth. Then, the electric push rod 9 is activated, moving the slider 5 and causing the dispensing syringe 6 and nozzle 7 to move up and down. Finally, the third motor 28 is energized, and through the meshing of the rotating gear 29, it drives the two rotating shafts 25 to rotate, causing them to move in opposite directions. The rotation of the cylinder causes two incomplete gears 26 to rotate. When one incomplete gear 26 meshes with the transmission rack 27, the other incomplete gear 26 will not mesh with the transmission rack 27. One incomplete gear 26, through meshing, will drive the extension plate 15 and the movable slider 4 to move their positions. After one incomplete gear 26 is no longer meshed with the transmission rack 27, the other incomplete gear 26 will contact the transmission rack 27 and drive the extension plate 15 and the movable slider 4 to move their positions in the opposite direction, thus completing the left and right movement of the dispensing syringe 6 and achieving the positional positioning effect of the dispensing nozzle 7.
