Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Embodiment one: please refer to Figures 1-8 , a kind of air conditioner compressor frequency converter circuit board burning detection unloader in the figure, including workbench 1 and fixedly installed on the top of workbench 1 feeding table 2, feeding table 2 is used to transport the circuit board to be detected, the top of workbench 1 is fixedly installed with detection table 3 and feeding table 4, the top of workbench 1 is rotatably installed with material placing turntable 5 below detection table 3, the top of material placing turntable 5 is fixedly installed with four material placing plates 6 that are centrally symmetrically distributed, the top of workbench 1 is fixedly installed with conveying frame 7 and two mechanical arms 8, and the two mechanical arms 8 are located at the outer side of feeding table 2 and the outer side of feeding table 4, the first mechanical arm 8 places the circuit board on feeding table 2 on the four material placing plates 6 on material placing turntable 5 in turn, the circuit board is transported to the lower side of detection table 3 by using the rotation of material placing turntable 5, so that detection table 3 detects the circuit board, and the qualified circuit board can be transported to conveying frame 7, the second mechanical arm 8 can place the unqualified circuit board on feeding table 4, to realize batch detection of the circuit board.

[0022] The unloading mechanism includes two V-shaped plates 9 mounted on top of the material placement plate 6. The V-shaped plates 9 can push the circuit board onto the conveyor frame 7. The unloading mechanism also includes two support seats 12 symmetrically arranged on the outer side of the V-shaped plates 9. A slide plate 13 is slidably mounted on the inner side of the support seat 12. An mounting plate 16 is fixedly mounted between the two slide plates 13. A movable plate 14 is fixedly mounted between two adjacent mounting plates 16. The surface of the material placement turntable 5 has four mounting slots located below the four material placement plates 6. A positioning frame 15 is fixedly mounted on the inner side of the mounting slot. A screw 44 is rotatably mounted on the inner side of the positioning frame 15. The movable plate 14 is slidably mounted on the inner side of the positioning frame 15, and the movable plate 14 is threaded onto the outer side of the positioning frame 15, so that when the screw 44 rotates, it can drive the movable plate 14 to move the movable plate 14. The plate 14 moves horizontally along the inner side of the positioning frame 15. The moving plate 14 drives the two mounting plates 16 to move synchronously, so that the mounting plates 16 drive the two sliding plates 13 to move synchronously. The sliding plates 13 drive the V-shaped plate 9 to move through the support base 12. The V-shaped plate 9 can then drive the circuit board to move. Multiple first tension springs 17 are fixedly installed between the inner side of the support base 12 and the top of the sliding plate 13. Slide rods 18 are rotatably installed on both sides of the support base 12. Positioning plates 19 are provided on both sides of the support base 12. The positioning plates 19 are fixedly installed on the inner side of the mounting groove. The surface of the positioning plate 19 has a guide groove for limiting the sliding of the slide rods 18, and one end of the guide groove is a bevel structure. The top of the material plate 6 has two material placement grooves for placing the circuit board, so that the slide rods 18 move along the guide grooves. When the inclined end moves, it can drive the support seat 12 to move upward along the outer side of the slide plate 13, and cause the support seat 12 to stretch the first tension spring 17, lifting the V-shaped plate 9 upward, so that the circuit board moves above the material placement groove. Then, the slide rod 18 moves horizontally along the inner side of the guide groove, so that the V-shaped plate 9 can push the circuit board onto the conveyor frame 7, realizing the rapid conveying of qualified circuit boards. When the slide rod 18 resets, the rebound force of the first tension spring 17 pulls the support seat 12 downward, so that the slide rod 18 moves and resets along the inclined end of the guide groove. Two symmetrically distributed limiting rings 36 are fixedly installed on the outer side of the slide rod 18. The corresponding sides of the two limiting rings 36 contact the two sides of the positioning plate 19, so that when the slide rod 18 moves, it can... The limit ring 36 can be moved along the outside of the positioning plate 19 to prevent the slide rod 18 from tilting. A U-shaped socket 37 is fixedly installed at one end of the screw 44. An annular groove is opened at the bottom of the material feeding turntable 5, and the U-shaped socket 37 extends to the inside of the annular groove. A drive motor 38 located inside the annular groove is fixedly installed on the top of the worktable 1. A plug plate 39 is fixedly installed at the output end of the drive motor 38. When the material feeding turntable 5 rotates, it can drive the U-shaped socket 37 on the screw 44 to align with the plug plate 39 on the drive motor 38. The plug plate 39 can be inserted into the inside of the U-shaped socket 37, so that the drive motor 38 drives the U-shaped socket 37 to rotate through the plug plate 39. The U-shaped socket 37 can then drive the screw 44 to rotate, which facilitates the unloading of the circuit board on the material feeding plate 6.

[0023] Example 2: Please refer to Figures 2-6This embodiment further illustrates Example 1. The material guiding mechanism shown in the figure includes two rotating rods 10 symmetrically fixedly installed at one end of the V-shaped plate 9. The rotating rods 10 can tilt the V-shaped plate 9 to unload material. The material guiding mechanism also includes two sleeve frames 20 symmetrically fixedly installed at the bottom of the V-shaped plate 9, with the openings of the sleeve frames 20 facing downwards. A fixing frame 21 is provided below the sleeve frame 20. One side of the fixing frame 21 is fixedly installed inside the mounting groove. A support bar 22 is provided on the top of the fixing frame 21. The top of the support bar 22 contacts the inner side of the sleeve frame 20, so that the two support bars 22 abut against the bottom of the sleeve frame 20, providing support for the bottom of the V-shaped plate 9, making the bottom of the V-shaped plate 9 horizontal, which facilitates the placement of the circuit board into the material placement groove and the V-shaped plate. On the surface of V-shaped plate 9, multiple equally spaced insert rods 23 are fixedly installed at the bottom of support bar 22. The insert rods 23 slide to the inside of fixed frame 21. A fixed plate 24 is fixedly installed between the ends of the multiple insert rods 23 away from support bar 22. A second tension spring 25 is sleeved on the outside of the insert rods 23, and the second tension spring 25 is fixedly installed between the inside of fixed frame 21 and the top of fixed plate 24. When V-shaped plate 9 moves upward, the elasticity of the second tension spring 25 can be used to pull fixed plate 24 to move. Fixed plate 24 drives insert rods 23 to drive support bar 22 to move, so that support bar 22 maintains support for V-shaped plate 9 through sleeve frame 20. Two rotating rods 10 are respectively rotatably installed on the inside of two support seats 12, so that support seats 12 can be pushed by rotating rods 10. As the V-shaped plate 9 moves, a rotating plate 26 is fixedly installed on the outer side of the rotating rod 10. An arc-shaped cavity for the rotating plate 26 to slide within a limited range is provided on the inner side of the support base 12. Multiple arc-shaped springs 27, evenly distributed, are fixedly installed between the outer side of the rotating plate 26 and the inner side of the arc-shaped cavity. When the support bar 22 provides support to the V-shaped plate 9, the rotating plate 26 can stretch the arc-shaped springs 27 and press against the inner side of the arc-shaped cavity, keeping the V-shaped plate 9 horizontal. When the V-shaped plate 9 moves towards the conveyor frame 7, the sleeve 20 at the bottom of the V-shaped plate 9 can move away from the support bar 22. The rebound force of the arc-shaped springs 27 pulls the rotating plate 26 to move and reset along the inner side of the arc-shaped cavity. The rotating plate 26 drives the rotating rod 10 to rotate, causing the rotating rod 10 to swing the V-shaped plate 9 downwards, facilitating the slide of the circuit board onto the conveyor frame 7. On the feed frame 7, an arc-shaped rod 40 is provided on the inner side of the arc-shaped spring 27. The arc-shaped rod 40 is fixedly installed on the inner side of the arc-shaped cavity, and the arc-shaped rod 40 slides through the rotating plate 26, so that when the rotating plate 26 moves, it can move along the outer side of the arc-shaped rod 40, so that the arc-shaped rod 40 provides guidance for the movement of the rotating plate 26, ensuring that the V-shaped plate 9 swings downward smoothly. Multiple equally spaced stop blocks 43 are fixedly installed on the inner side of the fixed frame 21, and the stop blocks 43 are located above the fixed plate 24, so that the stop blocks 43 provide a limit for the upward movement of the fixed plate 24, preventing the support bar 22 from moving too high. The size of the arc-shaped spring 27 can be determined according to the actual production situation. The size and number of the arc-shaped spring 27 only need to be sufficient to allow the V-shaped plate 9 to drive the circuit board to rebound and reset.

[0024] Example 3: Please refer to Figures 2-8 This embodiment further illustrates other embodiments. The pusher mechanism shown in the figure includes a pusher wheel 11 disposed on the outside of the V-shaped plate 9. The pusher wheel 11 enables the circuit board to be quickly separated from the V-shaped plate 9. The pusher mechanism also includes two support frames 28 symmetrically fixedly installed on the outside of the V-shaped plate 9. A first rack 29 and a second rack 30 are slidably installed on the inner side of the support frames 28. A driven rod 31 is rotatably installed between the two support frames 28. A support plate 32 is fixedly installed on the outside of the driven rod 31. The pusher wheel 11 is rotatably installed on the support plate 32. The end of the V-shaped plate 9 furthest from the driven rod 31 has an opening on its outer side corresponding to the support plate 32. This allows the driven rod 31 to rotate, causing the support plate 32 to swing downwards. The support plate 32 pushes the circuit board on the V-shaped plate 9 via the push wheel 11. This, combined with the push of the conveyor frame 7, ensures that the V-shaped plate 9 lands smoothly on the conveyor frame 7, preventing any tilting. Both ends of the driven rod 31 are fixedly equipped with first gears 33, which mesh with the first rack 29. The support base 12 is close to the V-shaped plate. A second gear 34 is fixedly installed on one side of the V-shaped plate 9. The second gear 34 is a half-gear structure. The second rack 30 meshes with the second gear 34. A connecting plate 35 is fixedly installed between the first rack 29 and the second rack 30. When the V-shaped plate 9 swings downward, it can drive the first rack 29 and the second rack 30 in the support frame 28 to swing synchronously. The second rack 30 moves along the outside of the second gear 34, so that the second rack 30 pulls the first rack 29 through the connecting plate 35. The first rack 29 can then be driven by the first gear 33. When the moving rod 31 rotates, two symmetrically distributed positioning ribs 41 are fixedly installed on the inner side of the support frame 28, and the outer side of the second rack 30 is provided with positioning grooves corresponding to the positioning ribs 41, so that the second rack 30 can move along the outer side of the positioning ribs 41, providing guidance and support for the movement of the second rack 30. Two symmetrically distributed baffles 42 are fixedly installed on the side of the V-shaped plate 9 near the support frame 28. The baffles 42 are in contact with the outer side of the support plate 32, so that the baffles 42 provide limit and support for the V-shaped plate 9 when it is reset.

[0025] Working Principle: First, the loading platform 2 conveys the circuit boards to be inspected, allowing the first robotic arm 8 to grab the circuit boards from the loading platform 2 and place them on the placement plates 6 on the placement turntable 5. Two circuit boards are inserted into the two mounting slots on the placement plate 6, with the bottom and outer sides of the circuit boards abutting against the surface of the V-shaped plate 9. Then, the placement turntable 5 drives the four placement plates 6 in a circular motion, causing the first robotic arm 8 to load the circuit boards onto empty placement plates 6. As the placement turntable 5 rotates, the placement plates 6 can move directly below the inspection platform 3, allowing the inspection platform 3 to inspect the circuit boards. After inspection, the placement plate 6 moves to one end of the conveyor frame 7. When there are defective circuit boards on the placement plate 6, the second robotic arm 8 removes the defective circuit boards from... The circuit board is removed from the placement plate 6 and sent to the feeding table 4 for conveying out defective circuit boards. The screw 44 below the placement plate 6 is aligned with the output end of the drive motor 38. The U-shaped socket 37 at the end of the screw 44 contacts the insertion plate 39 on the drive motor 38, allowing the insertion plate 39 to insert into the inside of the U-shaped socket 37. At this time, the drive motor 38 drives the screw 44 to rotate, causing the screw 44 to move the moving plate 14 horizontally along the inside of the positioning frame 15. The moving plate 14 then drives the two mounting plates 16 to move synchronously. The mounting plates 16 drive the support base 12 to move synchronously via the sliding plate 13, causing the support base 12 to drive the sliding rod 18 to move along the inclined end of the guide groove on the positioning plate 19. The sliding rod 18 can then move in an upward inclined state. The slide bar 18 pulls the support seat 12 upward along the outside of the slide plate 13. The support seat 12 pushes the V-shaped plate 9 upward through the rotating rod 10. The rebound force of the second tension spring 25 pulls the fixing plate 24 upward. The fixing plate 24 pushes the support bar 22 upward through the insert rod 23, so that the support bar 22 is attached to the sleeve 20 at the bottom of the V-shaped plate 9. The rotating plates 26 on the rotating rods 10 at both ends of the V-shaped plate 9 can abut against the arc-shaped cavity of the support seat 12, maintaining the tension of the arc-shaped spring 27. The support bar 22 can then cooperate with the rotating plates 26 to make the V-shaped plate 9 horizontal. Thus, the upward-moving V-shaped plate 9 lifts the circuit board. Subsequently, the slide bar 18 moves to the horizontal end of the guide groove, so that the support seat 12 drives the V-shaped plate 9 through the rotating rod 10. The V-shaped plate 9 moves horizontally, supporting the circuit board as it moves towards the conveyor frame 7. When the sleeve 20 at the bottom of the V-shaped plate 9 moves away from the support bar 22, the return force of the arc spring 27 causes the rotating plate 26 to drive the rotating rod 10 to rotate. The rotating rod 10 causes the V-shaped plate 9 to swing downward, so that one end of the circuit board contacts the surface of the conveyor frame 7. At the same time, the V-shaped plate 9 causes the two support frames 28 to swing synchronously, causing the second rack 30 inside the support frame 28 to swing downward along the outside of the second gear 34. The bottom end of the second rack 30 can then move downward, causing the second rack 30 to pull the first rack 29 to move through the connecting plate 35. The first rack 29 drives the first gear 33 to rotate, causing the first gear 33 to drive the support plate 32 to swing downward through the driven rod 31.The support plate 32 drives the pusher 11 to contact the outer side of the circuit board, providing thrust to the circuit board. Combined with the push-pull action of the conveyor frame 7, this ensures the bottom of the circuit board lands smoothly on the conveyor frame 7, preventing it from rolling over and improving the safety of the circuit board unloading process. Thus, two circuit boards on the placement plate 6 can be unloaded simultaneously, thereby improving the efficiency of circuit board inspection.
