Description
Technical Field
[0001] This invention belongs to the field of inverter manufacturing technology, specifically an inverter potting equipment. Background Technology
[0002] An inverter is a converter that transforms direct current (DC) power into alternating current (AC) power of fixed frequency and voltage or frequency and voltage regulation. It mainly consists of an inverter bridge, control logic, and filter circuits. When the inverter is working, it also consumes some power, and its input power is greater than its output power. The power consumed by the inverter is usually converted into heat and dissipated, causing the internal temperature of the inverter to rise with the use of the inverter. Especially for inverters used outdoors, excessively high ambient temperatures often affect the internal temperature and heat dissipation system of the inverter. Therefore, good heat dissipation directly affects the use of the inverter.
[0003] To improve the heat dissipation of inverters, thermally conductive adhesive is poured inside. This effectively enhances heat dissipation and also wraps and secures the internal electronic components, bonding the circuitry to the adhesive. This eliminates adverse effects from vibration and impact, making it safer to use. Even minor collisions will not affect its operation.
[0004] The thermally conductive adhesive inside the inverter is usually applied using a dispensing machine. A conveyor belt transports the inverter to the dispensing machine, which then injects the thermally conductive adhesive through the dispensing head until the machine is full. However, because the thermally conductive adhesive is viscous, a small amount of adhesive remains at the dispensing head after the dispensing process is complete. This residual adhesive can drip, causing contamination of the equipment. Furthermore, if it drips onto the outside of the inverter, it can affect the manufacturing quality of the inverter.
[0005] Therefore, the present invention provides an inverter potting device. Summary of the Invention
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this invention to solve its technical problem is as follows: An inverter potting device according to this invention includes a base; a support is fixedly connected to the top surface of the base, a moving platform is arranged in the middle of the support, a potting system is arranged at the bottom of the moving platform, and a potting blocking unit is arranged at the bottom of the moving platform; the potting blocking unit includes a rack, a rack is fixedly connected to the side of the potting system, a lead screw is rotatably mounted on the bottom side of the moving platform, a gear is fixedly connected to the outer ring of the lead screw near the rack, the gear meshes with the rack, a support beam is fixedly connected to the bottom side of the moving platform away from the potting system, a sliding plate is slidably mounted on the outer ring of the support beam, a threaded sleeve is arranged on the side of the sliding plate near the lead screw, the inner ring of the threaded sleeve is threadedly engaged with the outer ring of the lead screw, and a baffle is arranged on the bottom side of the sliding plate near the potting system; during operation, the moving platform carries the potting system to the top of the inverter at the top of the base, and the movement... The platform drives the dispensing head of the dispensing system to descend, causing the rack to move downwards, which in turn rotates the gear meshing with it, causing the lead screw to rotate. This, in conjunction with the threaded sleeve, drives the sliding plate along the support beam away from the dispensing system, causing the dispensing head of the baffle dispensing system to slide horizontally outwards. This allows the dispensing head of the dispensing system to enter the inverter for dispensing. Once the inverter is full of dispensing material, the dispensing system stops dispensing. Simultaneously, the moving platform drives the dispensing head of the dispensing system to rise, causing the rack to move upwards, which in turn rotates the gear meshing with it, causing the lead screw to rotate in reverse. Through the transmission of the threaded sleeve, the sliding plate moves along the support beam closer to the dispensing system, causing the baffle to slide past the lower end of the dispensing head and scrape off any remaining dispensing material. The dispensing system continues to rise, positioning the baffle below the dispensing head to prevent any remaining thermally conductive adhesive from dripping onto the inverter, thus improving the inverter's manufacturing quality and facilitating cleaning by personnel.
[0008] Preferably, the sliding plate has a mounting hole on the side near the lead screw. Multiple protrusions are fixedly connected to the inner ring of the mounting hole. The threaded sleeve is slidably installed inside the mounting hole. Multiple grooves are formed around the outer ring of the threaded sleeve. The protrusions slide into the grooves. A locking screw is threaded onto the outer side of the mounting hole. A rubber scraper is fixedly connected to the side of the baffle near the dispensing system. The sliding engagement between the protrusions and grooves prevents the threaded sleeve from rotating with the lead screw. By sliding the threaded sleeve inside the mounting hole, the operator adjusts the position of the sliding plate, controlling the distance between the sliding plate and the dispensing system. This adjusts the time it takes for the baffle to contact the bottom of the dispensing head of the dispensing system, reducing the probability of the baffle colliding with the dispensing head and improving overall safety.
[0009] Preferably, a pair of crossbars are fixed to the bottom of the slide plate near the glue-dispensing system. Multiple through holes are evenly distributed in the middle of the crossbars. Multiple long screws are provided in the middle of the baffle. The long screws slide through the baffle, and both ends of the long screws pass through the through holes. Rubber posts are fitted around the outer rings of both ends of the long screws. The baffle is installed and fixed between the two crossbars by the long screws. The multiple through holes facilitate the adjustment of the baffle position by the operator, which not only improves the blocking and interception of dripping thermally conductive adhesive, but also reduces the probability of the baffle hitting the glue-dispensing head of the glue-dispensing system.
[0010] Preferably, the bottom of the slide plate is fixedly connected to multiple convex rails on the side near the glue-dispensing system, and a collection bucket is provided on the bottom of the slide plate near the glue-dispensing system. The collection bucket is fixedly connected to multiple concave rails on the side near the slide plate, and the concave rails slide in cooperation with the convex rails. The collection bucket is located at the bottom of the baffle. During operation, the collection bucket is fixedly installed at the bottom of the baffle through the sliding cooperation between the convex rails and the concave rails. The thermally conductive adhesive intercepted at the top of the baffle slides into the interior of the collection bucket, thereby facilitating the subsequent collection and cleaning work of the staff and improving the convenience of the staff's work.
[0011] Preferably, a pair of guide rails are fixedly connected to the top surface of the base, and multiple sets of sliders are slidably installed on the top of the guide rails on both sides. A support plate is fixedly connected to the top surface of each set of sliders, and an inverter is placed on the top surface of the support plate. During operation, the slider slides along the guide rails, driving multiple support plates to be transported to the middle of the base at a constant and uniform speed, thereby transporting multiple inverters sequentially through the glue-filling system, thus realizing the automation of inverter glue-filling and improving the efficiency of inverter manufacturing.
[0012] Preferably, a circular groove is formed in the center of the top surface of the pallet, and a circular plate is slidably installed inside the groove. Multiple straight slots are evenly formed on the outer circumference of the circular plate. Multiple fixing nails are fixed to the outer circumference of the circular groove, and the fixing nails slide in engagement with the straight slots. Springs are fitted around the top and bottom outer circumferences of the fixing nails, with two springs located on the top and bottom surfaces of the circular plate. A ring plate is fixed to the bottom surface of the circular plate, and multiple arc grooves are formed around the bottom of the ring plate. A motor is located in the center of the base, and a rotating rod is provided on one side of the motor's shaft. The top of the rotating rod slides in engagement with the inner wall of the arc grooves. During operation, when the slider moves the support plate to the middle of the base, the motor drives the rotating rod to rotate. The rotating rod rotates along the arc groove at the bottom of the ring plate, pushing the circular plate to make a circumferential wave-like motion. This causes the straight groove on the outer ring of the circular plate to slide on the outer ring of the fixing nail, causing the spring on the top of one side of the circular plate to be compressed and the spring on the bottom to be reset. On the other side, the spring on the top is reset and the spring on the bottom is compressed, causing the inverter on the top of the circular plate to wobble in a circular motion. This reduces air bubbles inside the thermal conductive adhesive filled in the inverter, thereby improving the tightness of the thermal conductive adhesive filling and thus improving the heat dissipation efficiency of the inverter.
[0013] Preferably, the base has a mounting groove in the middle, and multiple guide strips are fixedly connected to the inner wall of the mounting groove. A lifting plate is slidably installed inside the mounting groove, and the outer concave surface of the lifting plate slides in cooperation with the guide strips. An electric push rod is fixedly connected to the bottom of the mounting groove, and the top of the sliding rod of the electric push rod is fixedly connected to the bottom surface of the lifting plate. The motor is attached to the middle of the top surface of the lifting plate. During operation, when the block moves the support plate to the middle of the base, the electric push rod pushes the lifting plate to slide upward along the guide strips, pushing the motor to move upward, so that the rotating rod is engaged in the arc groove. At the same time, the lifting height of the motor is controlled to control the amplitude of the inverter's sway, which is convenient for the operator to control. Furthermore, when the electric push rod drives the lifting plate to slide downward, it drives the motor and rotating rod to move downward, avoiding obstruction of the support plate's movement.
[0014] Preferably, a fixing block is threaded onto the top of the motor shaft. The outer ring of the fixing block is evenly provided with multiple convex grooves. A convex block is slidably installed inside one of the convex grooves, and the convex block and the convex groove are fixedly connected by bolts. The middle part of the convex block is fixedly connected to one end of the rotating rod. By slidably installing the convex block inside the convex groove, it is not only convenient for the operator to install and control the number and position of the rotating rods, but also convenient for the operator to control the height of the rotating rods.
[0015] Preferably, a fixed platform is fixedly connected to the top surface of the circular plate. A fixed groove is formed on the top surface of the fixed platform. Multiple positioning holes are formed around the bottom surface of the fixed groove. A card seat is slidably installed inside the fixed groove. Multiple positioning posts are fixedly connected around the bottom surface of the card seat. The outer wall of the positioning post slides in cooperation with the inner wall of the positioning hole. A placement groove is formed on the top surface of the card seat, and the placement groove matches the inverter. During operation, for inverters of different specifications and models, a suitable card seat is selected, and the positioning posts at the bottom of the card seat are slidably inserted into the positioning holes, so that the card seat is slidably installed inside the fixed groove. The inverter is placed inside the matching placement groove, which not only reduces the probability of displacement of the inverter during movement and glue filling, but also improves the applicability of the glue filling equipment.
[0016] Preferably, the bottom surface of the baffle is hinged with multiple elastic rods, and a torsion spring is provided at the hinge of the elastic rod. The top end of the elastic rod contacts the bottom of the baffle, and the bottom end of the elastic rod extends into the inside of the collection bucket. During operation, when the baffle slides past the bottom end of the dispensing head of the dispensing system, it scrapes off the thermally conductive adhesive at the bottom end of the dispensing head of the dispensing system. The remaining thermally conductive adhesive slides into the inside of the collection bucket along the elastic rod, thereby improving the collection efficiency of the thermally conductive adhesive.
[0017] The beneficial effects of this invention are as follows:
[0018] 1. The inverter potting equipment of the present invention comprises a moving platform, a potting system, a rack and pinion, a lead screw, a gear, a support beam, a sliding plate, a threaded sleeve, and a baffle. The moving platform carries the potting system to the top of the inverter at the top of the base. The moving platform drives the potting head of the potting system to move up and down, drives the rack and pinion to move, drives the gear meshing with it to rotate, drives the lead screw to rotate, and, in conjunction with the threaded sleeve, drives the sliding plate to move along the support beam towards and away from the potting system. This causes the baffle to move horizontally out and in from below the potting head of the potting system. The baffle slides past the lower end of the potting head of the potting system, scraping off the residual glue from the potting head. As the potting system continues to rise, the baffle is positioned below the potting head of the potting system, preventing the residual thermally conductive glue from dripping onto the inverter, thus improving the manufacturing quality of the inverter and facilitating cleaning work for the staff.
[0019] 2. The inverter potting equipment of the present invention comprises a circular plate, a fixing nail, a spring, a ring plate, a motor, and a rotating rod. When the slider moves the support plate to the middle of the base, the motor drives the rotating rod to rotate. The rotating rod rotates along the arc groove at the bottom of the ring plate, pushing the circular plate to make a circumferential wave-like motion. This causes the straight groove on the outer ring of the circular plate to slide on the outer ring of the fixing nail, causing the inverter at the top of the circular plate to wobble in a circular shape. This reduces air bubbles inside the thermally conductive adhesive potted inside the inverter, thereby improving the tightness of the thermally conductive adhesive potting and thus improving the heat dissipation efficiency of the inverter.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0033] Example 1
[0034] like Figures 1 to 3As shown in the figure, an inverter potting device according to an embodiment of the present invention includes a base 1; a bracket 2 is fixedly connected to the top surface of the base 1, a moving platform 3 is arranged in the middle of the bracket 2, a potting system 4 is arranged at the bottom of the moving platform 3, and a potting blocking unit is arranged at the bottom of the moving platform 3; the potting blocking unit includes a rack 6, the rack 6 is fixedly connected to the side of the potting system 4, a lead screw 7 is rotatably mounted on the bottom side of the moving platform 3, a gear 8 is fixedly connected to the outer ring of the end of the lead screw 7 near the rack 6, the gear 8 meshes with the rack 6, and the bottom of the moving platform 3 is away from the potting system. A support beam 9 is fixedly connected to one side of the 4. A slide plate 10 is slidably mounted on the outer ring of the support beam 9. A threaded sleeve 11 is provided on the side of the slide plate 10 near the lead screw 7. The inner ring of the threaded sleeve 11 is threadedly engaged with the outer ring of the lead screw 7. A baffle 12 is provided on the bottom side of the slide plate 10 near the glue-filling system 4. In this embodiment, the moving platform 3 is an XYZ high-precision moving platform, which is a platform that achieves precise movement in the X, Y, and Z directions. The XYZ platform mainly includes an X-axis moving part, a Y-axis moving part, and a Z-axis moving part. The couplings of each axis can be used to connect servo motors to achieve automatic adjustment. It can also be directly connected to the rotating disk for manual adjustment. During operation, the moving platform 3 carries the glue-filling system 4 to the top of the inverter on the base 1. The moving platform 3 drives the glue-filling head of the glue-filling system 4 to descend, causing the rack 6 to move downwards, rotating the meshing gear 8, and rotating the lead screw 7. This, in conjunction with the threaded sleeve 11, drives the sliding plate 10 along the support beam 9 away from the glue-filling system 4, causing the baffle 12 to move horizontally below the glue-filling head of the glue-filling system 4, allowing the glue-filling head of the glue-filling system 4 to enter the inverter for glue filling. Once the inverter is filled with glue, the glue-filling system 4 stops filling. Simultaneously, the moving platform 3... Platform 3 drives the dispensing head of the dispensing system 4 to rise, which in turn moves the rack 6 upward, causing the gear 8 meshing with it to reverse, and the lead screw 7 to reverse. Through the transmission of the threaded sleeve 11, the sliding plate 10 is driven to move along the support beam 9 and approach the dispensing system 4. This causes the baffle 12 to slide past the bottom of the dispensing head of the dispensing system 4, scraping off the residual glue. The dispensing system 4 continues to rise, so that the baffle 12 is located below the dispensing head of the dispensing system 4, preventing the residual thermally conductive glue from dripping onto the inverter. This improves the manufacturing quality of the inverter and facilitates the cleaning work of the staff.
[0035] like Figures 3 to 4As shown, the slide plate 10 has a mounting hole 13 on the side near the lead screw 7. Multiple protrusions 14 are fixedly connected to the inner ring of the mounting hole 13. The threaded sleeve 11 is slidably installed inside the mounting hole 13. Multiple grooves 15 are formed around the outer ring of the threaded sleeve 11. The protrusions 14 slide in conjunction with the grooves 15. A locking screw 16 is threaded onto the outer side of the mounting hole 13. A rubber scraper is fixedly connected to the side of the baffle 12 near the glue-dispensing system 4. The sliding contact between the protrusions 14 and the grooves 15 prevents the threaded sleeve 11 from rotating along with the lead screw 7. By sliding the threaded sleeve 11 inside the mounting hole 13, the operator adjusts the position of the slide plate 10, controls the distance between the slide plate 10 and the glue-dispensing system 4, and thus adjusts the time it takes for the baffle 12 to contact the bottom of the glue-dispensing head of the glue-dispensing system 4, reducing the probability of the baffle 12 hitting the glue-dispensing head of the glue-dispensing system 4 and improving overall safety.
[0036] like Figures 2 to 3 As shown, a pair of crossbars 17 are fixed to the bottom of the slide plate 10 near the glue-dispensing system 4. Multiple through holes 18 are evenly opened in the middle of the crossbars 17. Multiple long screws 19 are provided in the middle of the baffle 12. The long screws 19 slide through the baffle 12, and both ends of the long screws 19 pass through the through holes 18. Rubber posts 20 are sleeved on the outer rings of both ends of the long screws 19. The baffle 12 is installed and fixed between the two crossbars 17 by the long screws 19. The multiple through holes 18 make it easy for the staff to adjust the position of the baffle 12, which not only improves the blocking and interception of dripping thermal conductive glue, but also reduces the probability of the baffle 12 hitting the glue-dispensing head of the glue-dispensing system 4.
[0037] like Figures 2 to 3 As shown, a plurality of protruding rails 21 are fixedly connected to the bottom of the slide plate 10 near the glue-dispensing system 4. A collection bucket 22 is provided on the bottom of the slide plate 10 near the glue-dispensing system 4. A plurality of concave rails 23 are fixedly connected to the side of the collection bucket 22 near the slide plate 10. The concave rails 23 slide in cooperation with the protruding rails 21. The collection bucket 22 is located at the bottom of the baffle 12. During operation, the collection bucket 22 is fixedly installed at the bottom of the baffle 12 through the sliding cooperation between the protruding rails 21 and the concave rails 23. The thermally conductive adhesive intercepted at the top of the baffle 12 slides into the interior of the collection bucket 22, thereby facilitating the subsequent collection and cleaning work of the staff and improving the convenience of the staff's work.
[0038] like Figure 1 and Figure 5As shown, a pair of guide rails 24 are fixedly connected to the top surface of the base 1. Multiple sets of sliders 25 are slidably installed on the top of the guide rails 24 on both sides. A support plate 26 is fixedly connected to the top surface of each set of sliders 25. An inverter is placed on the top surface of the support plate 26. During operation, the sliders 25 slide along the guide rails 24, driving multiple support plates 26 to be transported to the middle of the base 1 at a constant and uniform speed. This allows multiple inverters to be transported sequentially through the glue-filling system 4, thereby realizing the automation of inverter glue-filling and improving the efficiency of inverter manufacturing.
[0039] like Figures 6 to 7 As shown, a circular groove 27 is formed in the center of the top surface of the support plate 26. A circular plate 28 is slidably installed inside the circular groove 27. Multiple straight slots 29 are evenly formed on the outer ring of the circular plate 28. Multiple fixing nails 30 are fixed to the outer ring of the circular groove 27. The fixing nails 30 slide with the straight slots 29. Springs 31 are sleeved on the top and bottom outer rings of the fixing nails 30, and two springs 31 are located on the top and bottom surfaces of the circular plate 28. A ring plate 32 is fixed to the bottom surface of the circular plate 28. Multiple arc grooves 33 are formed around the bottom of the ring plate 32. A motor 34 is set in the center of the base 1. A rotating rod 35 is set on one side of the rotating shaft of the motor 34. The top of the rotating rod 35 is connected to the inner arc groove 33. The wall slides; during operation, when the slider 25 moves the support plate 26 to the middle of the base 1, the motor 34 drives the rotating rod 35 to rotate. The rotating rod 35 rotates along the arc groove 33 at the bottom of the ring plate 32, pushing the circular plate 28 to make a circumferential wave-like motion. This causes the straight groove 29 on the outer ring of the circular plate 28 to slide on the outer ring of the fixing nail 30, causing the spring 31 on the top side of the circular plate 28 to be compressed and the spring 31 on the bottom side to be reset. The spring 31 on the top side of the other side is reset and the spring 31 on the bottom side is compressed, causing the inverter on the top of the circular plate 28 to wobble in a circular shape. This reduces the air bubbles inside the thermal conductive adhesive filled in the inverter, thereby improving the tightness of the thermal conductive adhesive filling and thus improving the heat dissipation efficiency of the inverter.
[0040] like Figure 6As shown, a mounting groove 36 is provided in the middle of the base 1. Multiple guide strips 37 are fixedly connected around the inner wall of the mounting groove 36. A lifting plate 38 is slidably installed inside the mounting groove 36. The outer concave surface of the lifting plate 38 is slidably engaged with the guide strips 37. An electric push rod 39 is fixedly connected to the bottom of the mounting groove 36. The top of the sliding rod of the electric push rod 39 is fixedly connected to the bottom surface of the lifting plate 38. The motor 34 is attached to the middle of the top surface of the lifting plate 38. During operation, when the slider 25 moves the support plate 26 to the middle of the base 1, the electric push rod 39 pushes the lifting plate 38 to slide upward along the guide strips 37, pushing the motor 34 to move upward, so that the rotating rod 35 is engaged in the arc groove 33. At the same time, the lifting height of the motor 34 is controlled to control the amplitude of the inverter's sway, making it easier for the operator to control. Furthermore, when the electric push rod 39 moves the lifting plate 38 downward, it moves the motor 34 and the rotating rod 35 downward, avoiding obstruction of the movement of the support plate 26.
[0041] like Figure 7 As shown, a fixing block 40 is threaded onto the top of the shaft of the motor 34. The outer ring of the fixing block 40 is evenly provided with multiple convex grooves 41. A convex block 42 is slidably installed inside one of the convex grooves 41, and the convex block 42 is fixed to the convex groove 41 by bolts. The middle part of the convex block 42 is fixed to one end of the rotating rod 35. By sliding the convex block 42 inside the convex groove 41, it is not only convenient for the staff to install and control the number and position of the rotating rod 35, but also convenient for the staff to control the height of the rotating rod 35.
[0042] like Figure 6 , Figure 8 and Figure 9 As shown, a fixed platform 43 is fixedly connected to the top surface of the circular plate 28. A fixed groove 44 is formed on the top surface of the fixed platform 43. Multiple positioning holes 45 are formed around the bottom surface of the fixed groove 44. A card seat 46 is slidably installed inside the fixed groove 44. Multiple positioning posts 47 are fixedly connected around the bottom surface of the card seat 46. The outer wall of the positioning post 47 slides in cooperation with the inner wall of the positioning hole 45. A placement groove 48 is formed on the top surface of the card seat 46. The placement groove 48 matches the inverter. During operation, for inverters of different specifications and models, a suitable card seat 46 is selected, and the positioning posts 47 at the bottom of the card seat 46 are slidably inserted into the positioning hole 45, so that the card seat 46 is slidably installed inside the fixed groove 44, and the inverter is placed inside the matching placement groove 48. This not only reduces the probability of displacement of the inverter during movement and glue filling, but also improves the applicability of the glue filling equipment.
[0043] Example 2
[0044] like Figure 10As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a plurality of elastic rods 49 are hinged to the bottom surface of the baffle 12, and a torsion spring is provided at the hinge of the elastic rod 49. The top end of the elastic rod 49 contacts the bottom of the baffle 12, and the bottom end of the elastic rod 49 extends into the inside of the collection bucket 22. During operation, when the baffle 12 slides past the bottom end of the dispensing head of the dispensing system 4, it scrapes off the thermally conductive adhesive at the bottom end of the dispensing head of the dispensing system 4. The remaining thermally conductive adhesive slides into the inside of the collection bucket 22 along the elastic rod 49, thereby improving the collection efficiency of the thermally conductive adhesive.
[0045] Working principle: For inverters of different specifications and models, select the appropriate card holder 46, slide the positioning post 47 at the bottom of the card holder 46 into the positioning hole 45, so that the card holder 46 is slidably installed in the fixed groove 44, and the inverter is placed in the matching placement groove 48; the slider 25 slides along the guide rail 24, driving multiple trays 26 to be transported to the middle of the base 1 at a constant and uniform speed, driving the inverter to move to the middle of the base 1;
[0046] The mobile platform 3 carries the glue-filling system 4 to the top of the inverter at the top of the base 1. The mobile platform 3 drives the glue-filling head of the glue-filling system 4 to descend, which drives the rack 6 to move downward, drives the gear 8 meshing with it to rotate, drives the lead screw 7 to rotate, and cooperates with the threaded sleeve 11 to drive the slide plate 10 to move away from the glue-filling system 4 along the support beam 9, and drives the baffle 12 to move horizontally out below the glue-filling head of the glue-filling system 4, so that the glue-filling head of the glue-filling system 4 enters the inverter for glue filling.
[0047] Simultaneously, the electric push rod 39 pushes the lifting plate 38 to slide upward along the guide bar 37, pushing the motor 34 to move upward, causing the rotating rod 35 to engage inside the arc groove 33. The motor 34 drives the rotating rod 35 to rotate, and the rotating rod 35 rotates along the arc groove 33 at the bottom of the ring plate 32, pushing the circular plate 28 to make a circumferential wave-like motion, causing the straight groove 29 on the outer ring of the circular plate 28 to slide on the outer ring of the fixing nail 30, causing the spring 31 on the top of the side of the circular plate 28 to be compressed, and the spring 31 at the bottom to be reset. The spring 31 on the top of the other side is reset, and the spring 31 at the bottom is compressed, causing the inverter at the top of the circular plate 28 to wobble in a circular shape, reducing the air bubbles inside the thermal conductive adhesive filled inside the inverter.
[0048] After the inverter is filled with glue, the glue-filling system 4 stops filling. The electric push rod 39 drives the lifting plate 38 to slide downward, which in turn drives the motor 34 and the rotating rod 35 to move downward. At the same time, the moving platform 3 drives the glue-filling head of the glue-filling system 4 to rise, which drives the rack 6 to move upward, which drives the gear 8 meshing with it to reverse, which drives the lead screw 7 to reverse. Through the transmission of the threaded sleeve 11, the sliding plate 10 is driven to move along the support beam 9 to approach the glue-filling system 4, which drives the baffle 12 to slide past the lower end of the glue-filling head of the glue-filling system 4, scraping off the glue remaining in the glue-filling head of the glue-filling system 4. The thermally conductive glue intercepted at the top of the baffle 12 slides into the inside of the collection bucket 22. The glue-filling system 4 continues to rise, so that the baffle 12 is located below the glue-filling head of the glue-filling system 4, preventing the thermally conductive glue remaining in the glue-filling head of the glue-filling system 4 from dripping onto the inverter, which improves the manufacturing quality of the inverter and facilitates the cleaning work of the staff.
