Description

Technical Field

[0001] This invention relates to a transformer flipping machine. Background Technology

[0002] During transformer assembly, due to space constraints, transformers on the previous conveyor line need to be flipped and transported to the next conveyor line on one side, with the two conveyor lines perpendicular to each other. Because the transformers are relatively heavy, manual flipping and handling is time-consuming, labor-intensive, and inefficient. Using robotic arms for flipping and handling would be costly. Furthermore, how to separate and recycle the tooling plate carrying the transformer from the transformer itself is a pressing technical problem that needs to be solved. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a transformer flipping machine that is labor-saving, efficient, low-cost, and capable of shunting the tooling plate and the transformer.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a transformer turning machine, comprising a base, an arc-shaped turning frame rotatably mounted on the base, the arc-shaped turning frame having two bearing surfaces, each bearing surface being provided with a roller line capable of rotating around itself, a workpiece groove being provided at the intersection of the two bearing surfaces, an electro-permanent magnet being provided on one of the bearing surfaces, a lifting conveyor platform being provided at the bearing surface where the electro-permanent magnet is provided, the conveying direction of the lifting conveyor platform being perpendicular to the conveying direction of the roller line, a synchronous lifting component being provided at the bottom of the lifting conveyor platform to drive the lifting conveyor platform to be higher or lower than the roller line, and a drive source being provided on the base to drive any one of the bearing surfaces to be in a horizontal position.

[0005] The beneficial effects of the transformer turning machine of the present invention are as follows: The lifting conveyor platform first rises above the roller conveyor, and connects to the tooling plate and the transformer placed on the tooling plate from the previous conveyor line. The feet of the transformer are exposed outside the tooling plate and located in the workpiece groove. After it is in position, the electro-permanent magnet attracts the tooling plate, and the drive source drives the arc-shaped turning frame to turn. Subsequently, the transformer and the tooling plate also turn until they are perpendicular to the horizontal plane. At this time, the transformer is in a state where it can detach from the tooling plate. The transformer is then transported away by the roller conveyor on the bearing surface without the electro-permanent magnet. The tooling plate continues to be attracted by the electro-permanent magnet. Then, the drive source controls the arc-shaped turning frame to turn in the opposite direction and restore the tooling plate to a horizontal state. The magnetic force of the electro-permanent magnet disappears. At the same time, the lifting conveyor platform descends below the roller conveyor, and the tooling plate is transported to the next conveyor line by the roller conveyor on the bearing surface with the electro-permanent magnet. By coordinating the above components, the transformer can be flipped and the current can be shunted. At the same time, the current shunting direction between the transformer and the tooling plate is changed, making it more suitable for workshops with small areas, improving its applicability. It replaces manual handling and flipping, and has the advantages of saving time and effort and high efficiency. In addition, its cost is lower than that of a robotic arm.

[0006] Preferably, the arc-shaped tilting frame includes multiple arc-shaped plates and multiple fixed connecting rods. The multiple arc-shaped plates are arranged parallel to each other and are fixedly connected by the multiple fixed connecting rods. The arc-shaped tilting frame is composed of multiple arc-shaped plates and fixed connecting rods, which saves materials and provides an installation position for the synchronous lifting assembly, resulting in a compact structure.

[0007] Preferably, the two outermost arc-shaped plates are provided with arc-shaped guide plates perpendicular to the arc-shaped plates on their circumference. Guide components for guiding the arc-shaped guide plates are provided on both sides of the base. Limiting components are provided on the two outermost arc-shaped plates. When the drive source drives the arc-shaped plates to rotate, the arc-shaped guide plates guide the arc-shaped plates to rotate along the guide components, and the limiting components restrict the continued rotation of the arc-shaped plates. This makes the rotation of the arc-shaped flipping frame more stable and provides a limiting effect on the arc-shaped flipping frame.

[0008] Preferably, the guiding assembly includes an inner tangent guide wheel and an outer tangent guide wheel mounted on the base. The inner tangent guide wheel is located inside and in contact with the arc-shaped guide plate, and the outer tangent guide wheel is located outside and in contact with the arc-shaped guide plate. Using the inner and outer tangent guide wheels to define the running trajectory of the arc-shaped guide plate makes the rotation of the arc-shaped tilting frame more stable.

[0009] Preferably, the outer guide wheel is located at the front and rear ends of the base, and the inner guide wheel is located in the middle of the base.

[0010] Preferably, the limiting member is a limiting plate fixed to two bearing surfaces, and the width of the limiting plate is greater than the thickness of the arc-shaped plate. The portion of the limiting plate extending beyond the arc-shaped plate blocks the outwardly tangential guide wheels at both ends, thereby achieving the blocking effect. The structure is simple and compact.

[0011] Preferably, the drive source is a motor, and the output end of the motor is provided with a sprocket. A chain is fixedly provided on the outer circumferential wall of one of the arc-shaped plates. The teeth of the sprocket are inserted into the chain and drive the arc-shaped plate to rotate.

[0012] Preferably, the synchronous lifting assembly includes two parallel first synchronous connecting rods and two parallel second synchronous connecting rods. The two ends of the two first synchronous connecting rods are rotatably connected to the two ends of the two second synchronous connecting rods via bearings. The two ends of each first synchronous connecting rod are rotatably connected to a rotating connecting rod. The other end of each rotating connecting rod is rotatably connected to a rotating shaft. The two ends of each rotating shaft are mounted on an arc-shaped tilting frame via bearings. A protruding connecting portion is integrally formed on the outer circumference of the upper end of each rotating connecting rod. The connecting portion is rotatably connected to the bottom of the lifting conveyor platform. A cylinder is provided on the outer side of each of the two second synchronous connecting rods. The tail of each cylinder is hinged to the arc-shaped tilting frame. The telescopic shaft of the cylinder is rotatably connected to the rotating connecting rod and drives the rotating connecting rod to rotate around the rotating shaft, thereby causing the connecting portion to rise and fall. This synchronous lifting assembly ensures the smooth lifting and lowering of the lifting conveyor platform.

[0013] Preferably, the arc-shaped plate located in the middle is provided with an arc-shaped movable hole, through which the first synchronizing link passes and can slide back and forth. Passing through the arc-shaped movable hole provides space for the movement of the first synchronizing link.

[0014] Preferably, the rollers on the bearing surface of the lifting conveyor platform have notches, and the lifting conveyor platform moves up and down within the notches. This makes the fit between the lifting conveyor platform and the rollers more compact. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0022] See appendix Figure 1-6 As shown, a transformer turning machine in this embodiment includes a base 10, on which an arc-shaped turning frame 20 is rotatably mounted. The arc-shaped turning frame 20 has two bearing surfaces 21, each bearing surface 21 having a roller 30 that can rotate around itself. A workpiece groove 27 is provided at the intersection of the two bearing surfaces 21. An electro-permanent magnet 70 is provided on one of the bearing surfaces 21. A lifting conveyor platform 40 is provided at the bearing surface 21 with the electro-permanent magnet 70. The conveying direction of the lifting conveyor platform 40 is perpendicular to the conveying direction of the roller 30. Specifically, the conveying direction of the lifting platform 40 is consistent with the conveying direction of the previous conveyor line, and the conveying direction of the roller 30 on the two bearing surfaces 21 is consistent with the conveying direction of the next conveyor line. A synchronous lifting component 50 is provided at the bottom of the lifting conveyor platform 40 to drive the lifting conveyor platform 40 to be higher or lower than the roller 30. Figure 5 As shown, the roller 30 on the bearing surface 21 of the lifting conveyor platform 40 has a notch 41. The lifting conveyor platform 40 moves up and down within the notch 41. The base 10 is equipped with a drive source 60 that drives any bearing surface 21 to be in a horizontal position.

[0023] The working principle of this embodiment:

[0024] During operation, the bearing surface 21 of the lifting conveyor platform 40 is horizontally positioned. The synchronous lifting component 50 drives the lifting conveyor platform 40 to rise above the roller conveyor 30 and connect with the previous conveyor line. The lifting conveyor platform 40 connects to the tooling plate and the transformer placed on the tooling plate from the previous conveyor line. The transformer's feet are exposed outside the tooling plate and located in the workpiece groove 27. The tooling plate of the transformer is driven by the lifting conveyor platform 40 to slide the transformer to the middle position of the lifting conveyor platform 40. After it reaches the middle position, the electro-permanent magnet 70 attracts the tooling plate, and the drive source 60 drives the arc-shaped tilting frame 20 to tilt. Subsequently, the transformer and the tooling plate also tilt until... With the transformer perpendicular to the horizontal plane, it is in a state where it can detach from the tooling plate. The transformer is then transported away by the roller conveyor 30 on the bearing surface without the electro-permanent magnet 70. The tooling plate continues to be attracted by the electro-permanent magnet 70. Subsequently, the drive source 60 controls the arc-shaped flipping frame 20 to flip in the opposite direction, restoring the tooling plate to a horizontal state. The magnetic force of the electro-permanent magnet 70 disappears, and it no longer attracts the tooling plate. The lifting conveyor platform descends below the roller conveyor 30, and the tooling plate is transported to the next conveyor line by the roller conveyor 30 on the bearing surface 21 with the electro-permanent magnet 70. This realizes the flipping transportation of the transformer (flipping from a horizontal position to a vertical position) and the diversion of the tooling plate.

[0025] The arc-shaped tilting frame 20 includes multiple arc-shaped plates 22 and multiple fixed connecting rods 23. The multiple arc-shaped plates 22 are arranged parallel to each other and are fixedly connected by the multiple fixed connecting rods 23. The fixed connecting rods 23 can adopt a square tube structure, which has a better connection effect. If the drive source 60 drives only one arc-shaped plate 22, the fixed connecting rod structure of the square tube can more easily drive the other arc-shaped plates 22 to rotate.

[0026] The rotatable connection between the arc-shaped tilting frame 20 and the base 10 is achieved using the following structure: Two arc-shaped plates 22 located on the outer sides are surrounded by arc-shaped guide plates 24 perpendicular to the arc-shaped plates 22. Guide assemblies 25 for guiding the arc-shaped guide plates 24 are provided on both sides of the base 10. The guide assembly 25 includes an inner tangent guide wheel 25a and an outer tangent guide wheel 25b mounted on the base 10. The inner tangent guide wheel 25a is located inside and in contact with the arc-shaped guide plate 24, while the outer tangent guide wheel 25b is located outside and in contact with the arc-shaped guide plate 24. The outer tangent guide wheel 25b is located at the front and rear ends of the base 10, and the inner tangent guide wheel 25a is located in the middle of the base 10. Limiting elements 26 are provided on the two outer arc-shaped plates 22, such as… Figure 4-6 As shown, in this embodiment, the limiting member 26 is a limiting plate fixed on two bearing surfaces 21, and the width of the limiting plate is greater than the thickness of the arc plate 22.

[0027] When the drive source 60 drives the arc plate 22 to rotate, the arc guide plate 24 guides the arc plate 22 to rotate along the guide assembly 25. Specifically, the arc plate 22 runs along the arc plate motion trajectory formed by two externally tangent guide wheels 25b and one internally tangent guide wheel 25b. When the arc-shaped flipping frame 20 rotates to the two extreme positions, the limiting plate on the bearing surface 21 blocks the externally tangent guide wheel 25b and limits its movement.

[0028] The drive source 60 is a motor 61, and the output end of the motor 61 is equipped with a sprocket 62. A chain 63 is fixedly mounted on the outer circumferential wall of one of the arc-shaped plates 22. The teeth of the sprocket 62 are inserted into the chain 63, driving the arc-shaped plate 22 to rotate. More preferably, in this embodiment, the chain 63 is mounted on the outer circumferential wall of the middle arc-shaped plate 22. In the attached drawings of this embodiment, there are three arc-shaped plates 22. When four arc-shaped plates 22 are used, the chain 63 can also be mounted on the two middle arc-shaped plates 22, and two sprockets 62 are mounted on the output end of the motor 61.

[0029] The synchronous lifting assembly 50 includes two parallel first synchronous connecting rods 51 and two parallel second synchronous connecting rods 52. The two ends of the two first synchronous connecting rods 51 are rotatably connected to the two ends of the two second synchronous connecting rods 52 via bearings 53. The two ends of each first synchronous connecting rod 51 are rotatably connected to a rotating connecting rod 54. The other end of each rotating connecting rod 54 is rotatably connected to a rotating shaft 55. The two ends of each rotating shaft 55 are mounted on the arc-shaped tilting frame 20 via bearings 53. A protruding connecting part 56 is integrally formed on the outer circumference of the upper end of each rotating connecting rod 54. The connecting part 56 is rotatably connected to the bottom of the lifting conveying platform 40. A cylinder 57 is provided on the outer side of each of the two second synchronous connecting rods 52. The tail of the cylinder 57 is hinged to the arc-shaped tilting frame 20. The telescopic shaft of the cylinder 57 is rotatably connected to the rotating connecting rod 54 and drives the rotating connecting rod 54 to rotate around the rotating shaft 55, thereby driving the connecting part 56 to rise and fall. The arc-shaped plate 22 located in the middle is provided with an arc-shaped movable hole 22a. The first synchronous connecting rod 51 passes through the arc-shaped movable hole 22a and can slide back and forth within the arc-shaped movable hole 22a.

[0030] In the synchronous lifting mechanism 50, the tail of the cylinder 57 is hinged to the lower square tube-shaped fixed connecting rod 23, and the rotating shaft 55 is mounted on the upper square tube-shaped fixed connecting rod 23 through bearings. Therefore, the square tube-shaped fixed connecting rod 23 can not only drive the other arc plates 22 to rotate, but also facilitate the installation of the tail of the cylinder 57 and the rotating shaft 55.

[0031] When the synchronous lifting mechanism 50 drives the lifting conveyor platform 40 to rise, the cylinder 57 drives the telescopic rod to extend, causing the rotating connecting rod 54 rotatably connected to it to rotate around the upper shaft 55. As the rotating connecting rod 54 rotates upward, the upper connecting part 56 rotates upward, thereby lifting the lifting conveyor platform 40 rotatably connected to it. When the synchronous lifting mechanism 50 drives the lifting conveyor platform 40 to descend, the cylinder 57 drives the telescopic rod to retract, causing the rotating connecting rod 54 rotatably connected to it to rotate downward around the upper shaft 55. As the rotating connecting rod 54 rotates downward, the upper integrally formed connecting part 56 rotates downward, thereby driving the lifting conveyor platform 40 rotatably connected to it to descend.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
