Description

Technical Field

[0001] This invention relates to the field of air conditioner compressor inverter production and assembly, specifically to a dispensing device for an automated production and assembly line of air conditioner compressor inverters. Background Technology

[0002] In the assembly and production of air conditioner compressor inverters, inductors need to be assembled with circuit boards. Special adhesive is used to fix the inductor pins to the circuit board. After the adhesive cures, it forms a high-strength adhesive layer that can suppress electromagnetic vibration and equipment operating vibration, prevent fatigue fracture of pin solder joints, and reduce noise generated by vibration.

[0003] Most current dispensing devices use a dispensing gun aligned with the inductor pins, allowing the needle to move along a preset path to dispense adhesive before curing. However, after dispensing adhesive to the current inductor, a certain amount of adhesive residue remains at the tip of the needle. If the needle is then used to dispense adhesive to the next inductor, the remaining adhesive will increase the amount of adhesive to be dispensed next time, which can easily cause adhesive overflow and affect the normal use of the inductor.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1-8 The figure shows a dispensing device for an automated production assembly line of an air conditioner compressor inverter. It includes a machine tool body 1 and a mounting box 2 installed inside the machine tool body 1. An electric slide table 3 is installed inside the mounting box 2, and a feeding tube 4 is installed outside the electric slide table 3. The electric slide table 3 can adjust the position of the feeding tube 4. A pressure control valve 5 is fixedly installed outside the feeding tube 4. A circular shell 6 is provided at one end of the feeding tube 4. Multiple dispensing needles 7 are centrally symmetrically distributed on the outside of the circular shell 6. Adhesive is fed into the feeding tube 4 and then dispensed onto the inductor and PCB board through the dispensing needles 7.

[0031] The adhesive removal mechanism includes a circular box 8 disposed on the outside of the circular shell 6. Multiple scrapers 9 are centrally symmetrically distributed on the outside of the circular box 8. The scrapers 9 can scrape off the adhesive overflowing from the dispensing needles 7. The adhesive removal mechanism also includes a mounting cover 12 fixedly installed on the outside of the circular shell 6. A positioning shaft 22 is fixedly installed on the inner side of the mounting cover 12. The circular box 8 is rotatably mounted on the outside of the positioning shaft 22. A rotating ring 13 is sleeved on the outside of the circular shell 6. The dispensing needles 7 are mounted on the outside of the rotating ring 13. Two symmetrically distributed toothed rings 14 are fixedly installed on the inner side of the rotating ring 13. A drive motor 15 is fixedly installed on the outside of the circular shell 6. The output end of the drive motor 15 extends to the inner side of the circular shell 6, and two gears 16, each meshing with one of the two toothed rings 14, are fixedly installed on the output end of the drive motor 15. When the drive motor 15 is running, it can drive the toothed rings 14 to rotate through the gears 16. The toothed rings 14 drive the rotating ring 13 to rotate along the outside of the circular shell 6, realizing the position replacement of multiple dispensing needles 7. A discharge pipe 17 is fixedly installed to connect with the feeding pipe 4, with the bottom end of the discharge pipe 17 facing downwards. As the rotating ring 13 rotates, the bottom end of the discharge pipe 17 aligns with the dispensing needle 7 located below the rotating ring 13. The glue in the feeding pipe 4 can then be fed into the dispensing needle 7 through the discharge pipe 17. A first synchronous belt 18 is rotatably installed between the output end of the drive motor 15 and the outer side of the circular box 8, enabling the drive motor 15 to drive the circular box 8 to rotate via the first synchronous belt 18. The circular box 8 then drives multiple scrapers. 9. Perform circular motion to clean the glue overflowing from the dispensing needle 7. A support arm 34 is fixedly installed between the outer side of the circular shell 6 and the outer side of the feeding tube 4. The circular shell 6 is connected to the end of the feeding tube 4 through the sleeve 35 to improve the firmness of the circular shell 6 installation. Multiple centrally symmetrical mounting seats 36 are fixedly installed on the outer side of the rotating ring 13. The number of mounting seats 36 is the same as the number of dispensing needles 7, and the dispensing needles 7 are connected to the mounting seats 36 through flanges to improve the convenience of dispensing needle installation.

[0032] Example 2: Please refer to Figures 4-8This embodiment further illustrates Example 1. The cleaning mechanism shown in the figure includes a pull block 10 fixedly installed at one end of the scraper 9. The pull block 10 can scrape off the glue on the surface of the scraper 9. The cleaning mechanism also includes a slide 19 slidably installed on the outside of the pull block 10. The slide 19 is fixedly installed on the inside of the circular box 8. Two symmetrically distributed support plates 20 are fixedly installed on the side of the pull block 10 away from the scraper 9. A pulley 21 is rotatably installed on the end of the support plate 20 away from the pull block 10. Two symmetrically distributed first discs 23 are fixedly installed on the outside of the positioning shaft 22. The first discs 23 have a semi-circular structure and... A second disc 24 is fixedly mounted on the plane of the first disc 23. The second disc 24 has a semi-circular structure. The first disc 23 and the second disc 24 are located between multiple pulleys 21. The outer diameter of the first disc 23 is larger than the size of the second disc 24. Two symmetrically distributed first tension springs 25 are fixedly installed between the pull block 10 and the inner side of the slide 19. The elasticity of the first tension springs 25 pulls the pull block 10. The pull block 10 drives the pulleys 21 to contact the first disc 23 or the second disc 24 through the support plate 20. When the circular box 8 rotates, the slide 19 can drive the pull block 10 to make a circle around the positioning shaft 22. The pulley 21 moves along the outer side of the first disc 23 or the second disc 24 using the elasticity of the first tension spring 25. When the pulley 21 moves from the first disc 23 to the second disc 24, the size difference between the first disc 23 and the second disc 24 causes the pulley 21 to pull the pull block 10 along the inner side of the slide 19 via the support plate 20. The pull block 10 then pulls the scraper 9 into the circular box 8, thus cleaning the glue on the scraper 9. A sleeve block 37 is fitted on the outer side of the scraper 9 and is fixedly installed on the outer side of the circular box 8, so that the scraper 9 can pass through the sleeve block 37 when moving. The impurities on the surface of the scraper 9 are cleaned, and the scraper 9 is guided and supported to move. Two symmetrically distributed inclined plates 38 are fixedly installed between the first disc 23 and the second disc 24, so that the pulley 21 can move from the first disc 23 to the second disc 24 or from the second disc 24 to the first disc 23 along the inclined plates 38. Two symmetrically distributed sliders 39 are fixedly installed on the outer side of the pull block 10, and the sliders 39 are slidably installed on the inner side of the slide 19, so that when the pull block 10 moves, it can drive the sliders 39 to move along the inner side of the slide 19, ensuring the smoothness of the movement of the pull block 10.

[0033] Example 3: Please refer to Figures 3-7This embodiment further illustrates other embodiments. The brushing mechanism shown in the figure includes a collection box 11 disposed on the outside of the circular box 8. The collection box 11 can collect and discharge the cleaned glue. The brushing mechanism also includes an insulation shell 26 fixedly installed inside the collection box 11. One end of the insulation shell 26 contacts the outside of the circular box 8. An arc-shaped scraper 27 is slidably installed on the inner side of the insulation shell 26. One end of the arc-shaped scraper 27 contacts the outside of the circular box 8, causing the circular box 8 to rotate and... When the scraper 9 is drawn into the circular box 8, the arc-shaped scraper 27 can scrape off the glue on the surface of the circular box 8, thus cleaning the circular box 8. A rotating drum 28 is rotatably mounted on the inner side of the collection box 11, and a heating rod 29 is provided on the inner side of the rotating drum 28. An electric heater 30 that is connected to the heating rod 29 is fixedly mounted on the outer side of the collection box 11, so that the electric heater 30 can heat the rotating drum 28 through the heating rod 29. Multiple stirring rods 31 are fixedly mounted on the outer side of the rotating drum 28, and the stirring rods 31 are conductive. The heating element 29 heats the stirring rod 31 via the rotating drum 28, causing the stirring rod 31 to heat the adhesive in the collection box 11 and maintain the adhesive in a fluid state. A second synchronous belt 32 is rotatably mounted between one end of the rotating drum 28 and the outer side of the circular box 8. When the circular box 8 rotates, the second synchronous belt 32 drives the rotating drum 28 to rotate, causing the rotating drum 28 to drive multiple stirring rods 31 to stir the adhesive in the insulation shell 26. The outer side of the collection box 11 is fixedly mounted with... A discharge valve 33 is provided to facilitate the discharge of flowing glue. A positioning block 40 is fixedly installed on the inner side of the insulation shell 26. Multiple support rods 41 are fixedly installed on the outer side of the arc-shaped scraper 27. The support rods 41 slide through the positioning block 40. A second tension spring 42 is sleeved on the outer side of the support rod 41 and is fixedly installed between the positioning block 40 and the arc-shaped scraper 27. The elasticity of the second tension spring 42 is used to make the arc-shaped scraper 27 press against the outer side of the circular box 8 to avoid gaps.

[0034] Working principle: First, the electric slide 3 drives the feeding tube 4 close to the inductor inside the machine tool body 1, causing the glue in the feeding tube 4 to be fed into the discharge tube 17. The glue in the discharge tube 17 enters the dispensing needle 7 directly below it, causing the dispensing needle 7 to perform glue dispensing operations on the inductor. Subsequently, the machine tool body 1 conveys the dispensed inductor out and conveys the next inductor directly below the feeding tube 4. At this time, the drive motor 15 drives the two gears 16 to rotate synchronously, causing the two gears 16 to drive the two gear rings 14 to rotate. The gear rings 14 drive the rotating ring 13 to rotate along the outer side of the circular shell 6, replacing the positions of the four dispensing needles 7, so that the next... Each dispensing needle 7 is aligned with the discharge tube 17, allowing the discharge tube 17 to dispense adhesive onto the inductor via the dispensing needle 7. Thus, as the drive motor 15 rotates, multiple dispensing needles 7 can be used sequentially. During this process, the drive motor 15 drives the circular box 8 to rotate via the first synchronous belt 18. The circular box 8 drives multiple scrapers 9 and multiple slides 19 to perform circular motion, causing the scrapers 9 to contact the outer side of the dispensing needle 7 and scrape away any excess adhesive from the tip of the dispensing needle 7. This ensures that each use of the dispensing needle 7 accurately dispenses adhesive onto the inductor. Simultaneously, the pull block 10 at the end of the scraper 9 drives the pulley 21 via the support plate 20 to connect with the first synchronous belt 18. When disc 23 or the second disc 24 comes into contact, and the circular box 8 rotates, the slide 19 drives the pull block 10 to move in a circular motion around the positioning shaft 22. Utilizing the elasticity of the first tension spring 25, the pulley 21 moves along the outer side of the first disc 23 or the second disc 24. When the pulley 21 moves from the first disc 23 to the second disc 24, the size difference between the first disc 23 and the second disc 24 causes the pulley 21 to pull the pull block 10 along the inner side of the slide 19 via the support plate 20. The pull block 10 then pulls the scraper 9 into the circular box 8, allowing the sleeve block 37 to scrape off the glue on the scraper 9, thus cleaning the glue from the scraper 9. Furthermore, the arc-shaped scraper 27 attached to the circular box 8 can scrape off the glue on the surface of the circular box 8 and the sleeve block 37, allowing the glue to enter the insulation shell 26. The circular box 8 drives the rotating drum 28 to rotate via the second synchronous belt 32, causing the rotating drum 28 to drive multiple stirring rods 31 to stir the glue in the insulation shell 26. At the same time, the electric heater 30 heats the stirring rods 31 on the outside of the rotating drum 28 via the heating rod 29, keeping the glue in a flowing state. Then, the glue is discharged through the discharge valve 33. Thus, the scraper 9 can continuously clean the glue on the dispensing needle 7, ensuring the accuracy of dispensing by the dispensing needle 7, and facilitating batch dispensing operations for inductors.
