[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A transformer frame testing device, comprising:

[0026] The conveyor belt 1, guide mechanism 2, limiting component 6, and moving component are provided. The upper end of the conveyor belt 1 is provided with guide mechanism 2 for guiding the transformer skeleton. The conveyor belt 1 is provided with limiting component 6 for limiting the defective transformer skeleton. The defective transformer skeleton is moved out of the conveyor belt 1 by moving component.

[0027] The guiding mechanism 2 includes a mounting frame 21, a bidirectional lead screw 22, a turntable 23, a limiting bolt 24, a moving plate 25, a guide rod 26, a silicone plate 27, and a straightening component 28. The upper end of the conveyor belt 1 is mounted on the bidirectional lead screw 22 through the mounting frame 21. One end of the bidirectional lead screw 22 is provided with a turntable 23, and the turntable 23 is limited by the limiting bolt 24. The outer side of the bidirectional lead screw 22 is connected to the guide rod 26 through the moving plate 25. A silicone plate 27 is provided between the guide rod 26 and the conveyor belt 1. The guide rod 26 is provided with a straightening component 28 for straightening the transformer frame.

[0028] For example, the limiting bolt 24 is released from the limiting position on the turntable 23, and the turntable 23 is rotated. The turntable 23 drives the bidirectional lead screw 22 to rotate, and the bidirectional lead screw 22 generates threaded movement with the moving plate 25, which drives the moving plate 25 to move. The moving plate 25 drives the guide rod 26 to move, and the guide rod 26 stretches the silicone plate 27. The two ends of the silicone plate 27 are fixed to the guide rod 26 and the side wall of the conveyor belt 1, respectively. Its elastic deformation allows the spacing of the guide rod 26 to be adjusted, while preventing the transformer frame from getting stuck in the gap. The guide rod 26 guides the transformer frame. When the guide rod 26 moves to a suitable position, the limiting bolt 24 limits the turntable 23. The side wall of the mounting frame 21 is provided with scales to facilitate observation of the distance moved by the moving plate 25.

[0029] The alignment component 28 includes a magnetic plate 281, an electromagnetic block 282, an elastic shell 283, and a first control switch 284. The guide rod 26 has a magnetic plate 281 inside, an electromagnetic block 282 inside, and a first control switch 284 electrically connected to the electromagnetic block 282 inside. An elastic shell 283 is located on the side of the first control switch 284 away from the guide rod 26.

[0030] For example, the transformer frame moves under the action of the guide rod 26, moving along the inclined side of the guide rod 26. When the transformer frame comes into contact with the elastic shell 283, it compresses the elastic shell 283. The elastic shell 283 then comes into contact with the first control switch 284, which controls the two electromagnetic blocks 282 to supply power. The electromagnetic blocks 282 generate a magnetic force that repels the magnetic plate 281, causing the two magnetic plates 281 to rotate and adjust the angle of the transformer frame. This prevents the tilted transformer frame from getting stuck on the other guide rod 26 when it moves along the inclined plate of the guide rod 26. To facilitate the movement of the transformer frame in the middle of the conveyor belt 1, after the transformer frame detaches from the elastic shell 283, it releases the pressure on the first control switch 284, making it easier to disconnect the power supply to the electromagnetic block 282. The end of the guide rod 26 is made of metal. After the electromagnetic block 282 is de-energized, the magnetic plate 281 and the end of the guide rod 26 generate an attractive force, which facilitates the reset of the magnetic plate 281. Under normal conditions, the magnetic plate 281 is attracted and fixed by the metal end of the guide rod 26. When the electromagnetic block 282 is energized, it generates a repulsive force, pushing the magnetic plate 281 to rotate. After the power is de-energized, the magnetic plate 281 resets. The recommended model of the electromagnetic block 282 is the SMC MQB series: a compact electromagnet with a fast response time. The recommended model of the first control switch 284 is the Omron D2F series micro switch: long life (more than 1 million times), tactile, suitable for triggering the elastic shell 283.

[0031] A fixed frame 3 is provided at the upper end of the conveyor belt 1, and an infrared sensor 4 and a CCD detection camera 5 are respectively installed on the fixed frame 3.

[0032] For example, the fixed frame 3 is used to install the infrared sensor 4 and the CCD inspection camera 5. After the infrared sensor 4 detects the transformer frame, the CCD inspection camera 5 takes a picture of the transformer frame for inspection. The recommended model of the infrared sensor 4 is Keyence FS-N11N: a compact photoelectric sensor suitable for high-precision position detection. The recommended model of the CCD inspection camera 5 is Baslerace series (such as acA1300-60gm): global shutter, supports GigE interface, and is suitable for industrial vision inspection.

[0033] The limiting component 6 includes a limiting frame 61, a first electric telescopic rod 62, a limiting plate 63, and a second control switch 64. The upper end of the conveyor belt 1 is provided with the first electric telescopic rod 62 through the limiting frame 61. The output end of the first electric telescopic rod 62 is provided with the second control switch 64 through the limiting plate 63. Sliders are provided on both sides of the limiting plate 63, and the inside of the limiting frame 61 is provided with a sliding groove that matches the slider.

[0034] For example, when the CCD inspection camera 5 detects a defective product, it transmits a signal to the controller. The controller controls the first electric telescopic rod 62 to open, and the output end of the first electric telescopic rod 62 extends, moving the limit plate 63 to the lowest end. When the limit plate 63 moves, the slider slides inside the groove to guide the limit plate 63. When the defective product touches the second control switch 64, the switch signal is transmitted to the controller, and the controller immediately stops the conveyor belt 1. The recommended model of the first electric telescopic rod 62 is the Linak LA23 series: an industrial-grade electric push rod with a thrust of up to 200N and built-in position feedback. The recommended model of the second control switch 64 is the Omron D2F series micro switch: long life (more than 1 million times) and tactile.

[0035] The moving component includes a second electric telescopic rod 7 and a push plate 8. The upper end of the conveyor belt 1 is provided with a push plate 8 via the second electric telescopic rod 7, and the conveyor belt 1 is electrically connected to the second control switch 64.

[0036] For example, the second electric telescopic rod 7 drives the push plate 8 to move. The push plate 8 pushes the defective product into the slot on one side of the conveyor belt 1 and slides out of the conveyor belt 1, falling onto the prepared loading platform. The recommended model of the second electric telescopic rod 7 is the Linak LA23 series: an industrial-grade electric push rod with a thrust of up to 200N and built-in position feedback. Based on the maximum weight of the transformer frame (e.g., 200g) and the friction coefficient of the conveyor belt, it is recommended to select an electric telescopic rod with a thrust ≥ 50N. The LA23 series has sufficient margin.

[0037] Working principle: When using this utility model, the transformer skeleton is intermittently placed on the upper end of the conveyor belt 1. The conveyor belt 1 transports the transformer skeleton, the guide mechanism 2 guides the transformer skeleton, the infrared sensor 4 detects the transformer skeleton, and the CCD detection camera 5 takes pictures of the transformer skeleton for detection. After one detection is completed, the detected transformer skeleton is flipped over and placed back on the conveyor belt 1 for detection on different sides.

[0038] When the CCD inspection camera 5 detects a defective product, it transmits a signal to the controller. The controller then controls the first electric telescopic rod 62 to open, and the output end of the first electric telescopic rod 62 extends, moving the limit plate 63 to the lowest point. When the limit plate 63 moves, the slider slides inside the groove, guiding the limit plate 63. When the defective product touches the second control switch 64, the switch signal is transmitted to the controller. The controller immediately stops the conveyor belt 1 and starts the second electric telescopic rod 7. The second electric telescopic rod 7 drives the push plate 8 to move. The push plate 8 pushes the defective product into the slot on one side of the conveyor belt 1, slides out of the conveyor belt 1, and falls onto the prepared loading platform. The controller then controls the first electric telescopic rod 62 and the second electric telescopic rod 7 to retract and starts the conveyor belt 1 for inspection.

[0039] Release the limiting bolt 24 from the turntable 23, rotate the turntable 23, and the turntable 23 drives the bidirectional lead screw 22 to rotate. The bidirectional lead screw 22 generates threaded motion with the moving plate 25, driving the moving plate 25 to move. The moving plate 25 drives the guide rod 26 to move, and the guide rod 26 stretches the silicone plate 27 and guides the transformer frame. When the guide rod 26 moves to a suitable position, the limiting bolt 24 limits the turntable 23. The transformer frame moves under the action of the guide rod 26 and moves on the inclined side of the guide rod 26. When the transformer frame comes into contact with the elastic shell 283, it squeezes the elastic shell 283. The elastic shell 283 comes into contact with the first control switch 284. The first control switch 284 controls the two electromagnetic blocks 282 to supply power. The electromagnetic blocks 282 generate a magnetic force that repels the magnetic plate 281. The two magnetic plates 281 rotate and adjust the angle of the transformer frame to facilitate the movement of the transformer frame in the middle position of the conveyor belt 1.

[0040] In this application, the control method of the electromagnetic block 282, the first control switch 284, the infrared sensor 4, the CCD detection camera 5, the first electric telescopic rod 62, the second control switch 64, and the second electric telescopic rod 7 is automatically controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
