Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] See attached document Figure 1 -Appendix Figure 8 A dispensing device for a chip dispensing machine includes a machine base 1. A Y-axis guide rail 2 and a Z-axis guide rail 3 are mounted on the machine base 1. A movable seat 4 is slidably mounted on the Z-axis guide rail 3. A fixed plate 5 is fixedly mounted on the outer surface of the movable seat 4. Two distance sensors 38 are symmetrically fixedly mounted on the lower surfaces of the fixed plate 5 on both sides of a first electric telescopic rod 6. The first electric telescopic rod 6 is fixedly mounted on the upper surface of the fixed plate 5. The telescopic end of the first electric telescopic rod 6 passes through the lower surface of the fixed plate 5 and is fixedly mounted with a dispensing head 7. A vertical plate 8 is fixedly mounted on the lower surface of the fixed plate 5. A [missing information - likely a device or component] is fixedly mounted on the outer surface of the vertical plate 8 on the side away from the dispensing head 7. The second electric telescopic rod 9 has a connecting frame 10 fixedly installed at its telescopic end through the outer surface of the vertical plate 8. A fixed plate 11 is fixedly installed on the outer surface of the connecting frame 10. A tray 12 is rotatably installed on the upper surface of the fixed plate 11 via a rotating shaft 15. The tray 12 is filled with absorbent sponge to absorb the adhesive dripping from the dispensing head 7, preventing the adhesive from dripping onto the chip. A bracket 13 is fixedly installed at the top of the tray 12. A brush block 14 is fixedly installed at one end of the bracket 13 near the center of the tray 12. A rotating mechanism is provided between the connecting frame 10 and the tray 12. A glue supply mechanism is provided on the upper surface of the machine base 1.

[0030] In this embodiment, the rotating mechanism includes a support plate 20 fixedly installed on one side of the connecting frame 10. A guide rod 21 is inserted through the outer surface of the support plate 20. A hollow rack 22 is fixedly installed between the two ends of the guide rod 21. A toothed ring 16 is rotatably installed on the lower surface of the fixed disk 11. The bottom end of the rotating shaft 15 passes through the lower surface of the fixed disk 11 and a turntable 17 is fixedly installed. The toothed ring 16 meshes with the hollow rack 22. A ratchet assembly is provided between the toothed ring 16 and the turntable 17. A power storage assembly is provided between the hollow rack 22 and the fixed plate 5. The ratchet assembly includes multiple pawls 18 rotatably installed on the inner wall of the toothed ring 16 at equal intervals in the circumferential direction. Multiple slots 19 that match the pawls 18 are evenly opened in the circumferential direction on the outer surface of the turntable 17.

[0031] When the fixed plate 11 moves the tray 12 toward the dispensing head 7, the toothed ring 16, which is mounted on the lower surface of the fixed plate 11, will roll on the hollow rack 22. Since the toothed ring 16 and the turntable 17 are engaged by the pawl 18 and the slot 19, the toothed ring 16 will not drive the turntable 17 to rotate when it rotates, so that the brush block 14 will not rotate. This prevents the brush block 14 from deflecting before it comes into contact with the dispensing head 7, thus avoiding a collision between the brush block 14 and the dispensing head 7.

[0032] In this embodiment, the power storage component includes a support frame 25 fixedly installed on the lower surface of the fixed plate 5. Two spring rods 26 are fixedly installed at the bottom end of the support frame 25. Push blocks 27 are fixedly installed at the telescopic ends of the two spring rods 26. Two stops 28 are fixedly installed at the bottom end of the push blocks 27. A compression spring 23 is sleeved on the outer surface of the guide rod 21. The compression spring 23 is disposed between the inner wall of the support plate 20 and the hollow rack 22 away from the vertical plate 8. An unlocking component is provided on the outer surface of the support plate 20. The unlocking component includes a push plate 24 fixedly installed on the outer surface of the support plate 20 near the push block 27. The outer surface of the push block 27 near the push plate 24 is set as an inclined surface.

[0033] In use, the telescopic end of the first electric telescopic rod 6 drives the dispensing head 7 to move downwards to dispense glue to the chip. When the dispensing head 7 moves to both sides of the machine 1 for alternating dispensing, the distance sensor 38 installed on the fixed plate 5 will detect that the dispensing head 7 is at the side and activate the second electric telescopic rod 9, causing the second electric telescopic rod 9 to push the fixed plate 11 downwards towards the dispensing head 7. At this time, the support plate 20 fixedly installed with the fixed plate 11 will move accordingly. Since the end of the hollow rack 22 is blocked by the stop block 28 at the bottom of the push block 27, the hollow rack 22 cannot be pushed. The compression spring 23 sleeved on the guide rod 21 will be compressed by the support plate 20 to store force. After the end of the push plate 24 fixedly installed on the support plate 20 abuts against the inclined surface of the push block 27, the push plate 24 will push the push block 27 upwards, causing the stop block at the bottom of the push block 27 to move upwards. 28. Unlock the hollow rack 22 so that the compression spring 23 can push the hollow rack 22, causing the hollow rack 22 to drive the meshing gear ring 16 to rotate. The gear ring 16, under the action of the ratchet assembly, drives the turntable 17 to rotate. The turntable 17 drives the tray 12 to rotate through the rotating shaft 15. The bracket 13 fixedly installed on the tray 12 drives the brush block 14 to rotate, so that the brush block 14 wipes the dispensing head 7's dispensing port, preventing residual glue from forming droplets or films, which would affect the next dispensing operation and cause poor glue droplets, affecting the dispensing quality. The transmission stroke of the hollow rack 22 and the gear ring 16 is fixed, so that the brush block 14 can automatically return to the side close to the vertical plate 8 after rotation, preventing the brush block 14 from colliding with the dispensing head 7 during movement and causing damage to the dispensing head 7.

[0034] In this embodiment, the glue supply mechanism includes a gantry frame 29 fixedly installed on the upper surface of the machine base 1. Multiple support rods 33 are evenly inserted through the upper surface of the gantry frame 29. A glue storage cylinder 30 is fixedly installed at the top of the multiple support rods 33. A limit ring 34 is fixedly installed at the bottom of the support rods 33. A return spring 35 is sleeved on the outer surface of the support rods 33. The return spring 35 is located between the lower surface of the gantry frame 29 and the upper surface of the limit ring 34. The return spring 35 is used to assist the glue storage cylinder 30 to quickly return to its original position. A stirring mechanism is provided inside the glue storage cylinder 30. The stirring mechanism includes a drive motor 32 fixedly installed at the top of the glue storage cylinder 30. The output end of the drive motor 32 passes through the top wall of the glue storage cylinder 30 and is fixedly installed with a stirring shaft 31. The bottom end of the stirring shaft 31 passes through the bottom of the glue storage cylinder 30 and is rotatably installed therewith. A vibration component is provided between the bottom end of the stirring shaft 31 and the top end of the gantry frame 29.

[0035] In use, the stirring shaft 31 is driven to rotate by the drive motor 32, so that the stirring shaft 31 slowly stirs the glue in the glue storage cylinder 30, so as to release the air bubbles in the glue and improve the accuracy of glue supply.

[0036] In this embodiment, the vibration assembly includes a support plate 36 fixedly installed at the bottom of the stirring shaft 31, and a support plate 36 fixedly installed at the top of the gantry frame 29. Multiple top beads 37 are fixedly installed at equal intervals on the outer surfaces of adjacent sides of the two support plates 36.

[0037] During use, the stirring shaft 31 drives the support plate 36 fixedly installed at its bottom to rotate, so that the top bead 37 fixedly installed on the support plate 36 can lift or lower each other with the top bead 37 installed at the top of the gantry frame 29, thereby causing the glue storage cylinder 30 to vibrate up and down, further releasing air bubbles in the glue and increasing the concentration of the glue.

[0038] In this embodiment, a metering pump 39 is fixedly installed on the upper surface of the machine 1. The metering pump 39 is connected to the inside of the glue storage cylinder 30 and the glue dispensing head 7 through a hose. The metering pump 39 can accurately pump the glue in the glue storage cylinder 30 into the glue dispensing head 7, ensuring accurate glue dispensing.

[0039] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: In use, multiple chips to be dispensed are placed equidistantly on the machine 1, and the dispensing head 7 is moved by the Y-axis guide rail 2, Z-axis guide rail 3 and moving seat 4 to perform dispensing operations on multiple chips.

[0040] During dispensing, the telescopic end of the first electric telescopic rod 6 drives the dispensing head 7 downward to dispense the chip. When the dispensing head 7 moves to both sides of the machine 1 for alternating dispensing, the distance sensor 38 installed on the fixed plate 5 will detect that the dispensing head 7 is at the side and activate the second electric telescopic rod 9, causing the second electric telescopic rod 9 to push the fixed plate 11 downward to the dispensing head 7. At this time, the support plate 20 fixedly installed with the fixed plate 11 will move accordingly. Since the end of the hollow rack 22 is blocked by the stop block 28 at the bottom of the push block 27, the hollow rack 22 cannot be pushed. The compression spring 23 sleeved on the guide rod 21 will be compressed by the support plate 20 to store force. After the end of the push plate 24 fixedly installed on the support plate 20 abuts against the inclined surface of the push block 27, the push plate 24 will push the push block 27 upward, causing the stop block at the bottom of the push block 27 to move upward. 28. Unlock the hollow rack 22 so that the compression spring 23 can push the hollow rack 22, causing the hollow rack 22 to drive the meshing gear ring 16 to rotate. The gear ring 16 can drive the turntable 17 to rotate under the action of the ratchet assembly. The turntable 17 drives the tray 12 to rotate through the rotating shaft 15. The bracket 13 fixedly installed on the tray 12 drives the brush block 14 to rotate. The brush block 14 wipes the glue outlet of the dispensing head 7 to prevent the glue residue at the glue outlet of the dispensing head 7 from forming droplets or films, which would affect the next dispensing operation and cause the formation of bad glue droplets, affecting the dispensing quality. The transmission stroke of the hollow rack 22 and the gear ring 16 is fixed so that the brush block 14 can automatically return to the side close to the vertical plate 8 after rotation, avoiding the brush block 14 from colliding with the dispensing head 7 during movement and causing damage to the dispensing head 7.

[0041] The stirring shaft 31 is driven to rotate by the drive motor 32, so that the stirring shaft 31 slowly stirs the glue liquid in the glue storage cylinder 30 in order to release the air bubbles in the glue liquid and improve the accuracy of glue supply.

[0042] While the stirring shaft 31 rotates, the stirring shaft 31 will drive the support plate 36 fixedly installed at its bottom to rotate, so that the top bead 37 fixedly installed on the support plate 36 can lift or lower each other with the top bead 37 installed at the top of the gantry frame 29, thereby causing the glue storage cylinder 30 to vibrate up and down, further releasing the air bubbles in the glue and increasing the concentration of the glue.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
