Description

Technical Field

[0001] This utility model relates to the technical field of copper sleeve production, specifically to an automatic copper sleeve loading, unloading, detection, and screening device. Background Technology

[0002] Copper bushings, also known as copper sleeves, come in various types, including machine copper rollers and copper bearings. They are used in various light industrial, large, and heavy machinery and are important components of machinery. Copper bushing machining refers to the processing of copper materials to produce precision copper bushing parts. After the copper bushing is machined with holes, the inner diameter of the hole generally needs to be inspected.

[0003] According to Chinese Patent No. CN221335485U, a mechanical parts processing device includes a workbench, a belt conveyor is provided on one side of the workbench, and frames are fixedly installed on both sides of the top of the workbench and the belt conveyor. A first motor is provided on the top of the right side of the frame away from the belt conveyor. A first lead screw is provided on the top of each of the two frames, and a slide is movably installed on the outside of the two first lead screws. A synchronization mechanism is provided on both sides of the top of the slide.

[0004] In the above scheme, the copper sleeve is placed on the belt conveyor by the electric gripper on the left, then inspected by the inner diameter measuring head, and then qualified copper sleeves are picked up by the electric gripper on the right. This results in the following disadvantages: the classification method of copper sleeves is cumbersome and the processing speed is slow, which makes it impossible to guarantee efficient classification and thus reduces the classification efficiency of copper sleeves. Utility Model Content

[0005] The purpose of this invention is to provide an automatic loading, unloading, detection, and screening device for copper sleeves, in order to solve the problem that the current device has a cumbersome classification method for copper sleeves, slow processing speed, and thus cannot guarantee efficient classification, thereby reducing the efficiency of copper sleeve classification.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an automatic loading and unloading detection and screening device for copper sleeves, comprising a U-shaped frame, the U-shaped frame being fixed on the top surface of a U-shaped base, the top surface of the U-shaped frame having an movable hole, a PLC controller being fixed on the right side of the outer wall of the U-shaped base, an electric push rod being fixed on the top surface of the U-shaped frame, the electric push rod being electrically connected to the PLC controller, an inner diameter measuring head being movably provided at one end of the telescopic rod of the electric push rod, the inner diameter measuring head being electrically connected to the PLC controller, a conveyor belt being provided inside the U-shaped base, the conveyor belt being electrically connected to the PLC controller, a mounting frame being fixed on the top surface of the U-shaped base, a drive motor being fixed on the inner top surface of the mounting frame, the drive motor being electrically connected to the PLC controller, and a guide plate being fixed on the output shaft of the drive motor.

[0007] Preferably, a connecting frame is fixed to the top surface of the U-shaped base, and an infrared sensor is fixed to the inner top surface of the connecting frame. The infrared sensor is electrically connected to the PLC controller.

[0008] Preferably, one end of the electric push rod telescopic rod is fixed with a guide rail, the guide rail is electrically connected to the PLC controller, the bottom surface of the slider of the guide rail is fixed with a connecting plate, and the bottom surface of the connecting plate is fixedly connected to the top end of the inner diameter measuring head.

[0009] Preferably, a qualified container is fixed to the rear side of the U-shaped base, and a waste container is fixed to the rear side of the U-shaped base.

[0010] Preferably, the top surface of the U-shaped frame has two limiting holes, and limiting posts are slidably inserted into the two limiting holes respectively. The bottom ends of the two limiting posts are fixedly connected to the top surface of the guide rail respectively.

[0011] Preferably, the bottom surfaces of the qualified bin and the waste bin are respectively fixed with buffer plates, and the top surfaces of the two buffer plates are respectively fixed with buffer pads.

[0012] Compared with existing technologies, the automatic loading, unloading, detection, and screening device for copper sleeves that adopts the above technical solution has the following beneficial effects:

[0013] 1. During use, the operator first places the copper sleeve to be tested on the conveyor belt, ensuring the through hole of the copper sleeve is facing upwards and vertical. Then, the conveyor belt is started to transport the copper sleeve. When the copper sleeve moves to below the inner diameter measuring head, the conveyor belt is stopped, and the position of the inner diameter measuring head is adjusted so that it is directly above the copper sleeve. Next, the electric push rod is started to move the inner diameter measuring head downwards into the copper sleeve to test the inner diameter of the copper sleeve. After the test is completed, the inner diameter measuring head is reset, and the information is transmitted to the PLC controller. The conveyor belt is then started to transport the copper sleeve. When the copper sleeve is qualified, the drive motor is started to rotate the guide plate clockwise, moving the copper sleeve to the right side of the guide plate for easy collection of qualified copper sleeves. Conversely, when the copper sleeve is unqualified, the drive motor is started to rotate the guide plate counterclockwise, moving the copper sleeve to the left side of the guide plate for easy collection of unqualified copper sleeves. The use of U-shaped frame, U-shaped seat, electric push rod, inner diameter measuring head, conveyor belt, mounting bracket, drive motor and guide plate facilitates automatic loading and unloading inspection of copper bushings, and can more quickly classify qualified and unqualified copper bushings, ensuring efficient classification of copper bushings and thus improving classification efficiency.

[0014] II. During use, the copper sleeve is conveyed by a conveyor belt. When the copper sleeve enters the detection range of the infrared sensor, it immediately captures the signal and transmits this information to the PLC controller. Upon receiving the signal, the PLC controller immediately starts the corresponding program, controlling the conveyor belt to stop running within three seconds. This ensures that the copper sleeve can stop below the inner diameter measuring head, providing a positioning basis for subsequent inner diameter measurement. After the infrared sensor detects the position of the copper sleeve, the PLC controller starts the guide rail, which drives the slider to move the inner diameter measuring head left and right, adjusting its position to align with the copper sleeve, ensuring the accurate positioning of the inner diameter measuring head.

[0015] Thirdly, during use, after the copper bushing undergoes inner diameter testing, qualified copper bushings are guided by the guide plate to the qualified bin for collection, while unqualified copper bushings are guided to the scrap bin for unified processing, ensuring separate collection of qualified and unqualified copper bushings. The use of limiting holes and limiting posts effectively limits the guide rail, preventing deviation during the raising and lowering of the guide rail and inner diameter measuring head, thus improving the stability of the guide rail and inner diameter measuring head during lifting and lowering. The use of buffer plates and buffer pads ensures that when the copper bushing enters the qualified bin and scrap bin, it first contacts the buffer pad on the buffer plate, effectively absorbing the impact force when the copper bushing falls, preventing damage or deformation due to impact, and improving the protective effect of the copper bushing.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-3As shown, an automatic loading, unloading, inspection, and screening device for copper sleeves includes a U-shaped frame 1, which is fixed to the top surface of a U-shaped base 2. The top surface of the U-shaped frame 1 has a movable hole 3. A PLC controller, specifically a Siemens S7-200, is fixed to the right side of the outer wall of the U-shaped base 2. An electric push rod 4 is fixed to the top surface of the U-shaped frame 1 and is electrically connected to the PLC controller. One end of the telescopic rod of the electric push rod 4 is movably equipped with an inner diameter measuring head 5, which is connected to the PLC controller. The device is electrically connected. The inner diameter measuring head 5 is an existing structure, which can be referred to in Chinese Patent Publication No. CN221335485U. The inner diameter measuring head 5 in this application document is the same as the inner diameter measuring head in the referenced document. The U-shaped base 2 is equipped with a conveyor belt 6 inside, which is electrically connected to the PLC controller. The top surface of the U-shaped base 2 is fixed with a mounting bracket 7, and the top surface inside the mounting bracket 7 is fixed with a drive motor 8. The drive motor 8 is electrically connected to the PLC controller, and the output shaft of the drive motor 8 is fixed with a guide plate 9.

[0023] In operation, the operator first places the copper sleeve to be tested on the conveyor belt 6, ensuring that the through hole of the copper sleeve is facing upwards and vertical. Then, the conveyor belt 6 is started to transport the copper sleeve. When the copper sleeve moves below the inner diameter measuring head 5, the conveyor belt 6 is stopped, and the position of the inner diameter measuring head 5 is adjusted so that it is directly above the copper sleeve. Then, the electric push rod 4 is started to move the inner diameter measuring head 5 downwards into the copper sleeve to measure the inner diameter of the copper sleeve. After the measurement is completed, the inner diameter measuring head 5 is reset, and the measurement result is transmitted to the PLC controller. The PLC controller controls the start of the conveyor belt 6 to continue transporting the copper sleeve. When the PLC controller determines that the copper sleeve is qualified, the PLC controller controls the start drive motor 8 to rotate forward, causing the guide plate 9 to rotate clockwise, so that the copper sleeve moves to the right side of the guide plate 9, which is convenient for subsequent collection of qualified copper sleeves. Conversely, when the PLC controller determines that the copper sleeve is unqualified, the PLC controller controls the start drive motor 8 to rotate in the opposite direction, causing the guide plate 9 to rotate counterclockwise, so that the copper sleeve moves to the left side of the guide plate 9, which is convenient for subsequent collection of unqualified copper sleeves.

[0024] The combined use of U-shaped frame 1, U-shaped seat 2, electric push rod 4, inner diameter measuring head 5, conveyor belt 6, mounting bracket 7, drive motor 8 and guide plate 9 facilitates automatic loading and unloading inspection of copper bushings, enabling faster classification of qualified and unqualified copper bushings, ensuring efficient classification of copper bushings, and thus improving classification efficiency.

[0025] like Figure 1 and Figure 2 As shown, a connecting frame 10 is fixed on the top surface of the U-shaped base 2, and an infrared sensor 11 is fixed on the inner top surface of the connecting frame 10. The infrared sensor 11 is electrically connected to the PLC controller.

[0026] During use, the copper sleeve is conveyed by the conveyor belt 6. When the copper sleeve enters the detection range of the infrared sensor 11, it immediately captures the signal and transmits this information to the PLC controller. After receiving the signal, the PLC controller immediately starts the corresponding program and controls the conveyor belt 6 to stop running within three seconds, ensuring that the copper sleeve can stay below the inner diameter measuring head 5, providing a positioning basis for subsequent inner diameter detection.

[0027] like Figures 1-3 As shown, one end of the telescopic rod of the electric push rod 4 is fixed with a guide rail 12. The guide rail 12 is electrically connected to the PLC controller. The bottom surface of the slider of the guide rail 12 is fixed with a connecting plate 13. The bottom surface of the connecting plate 13 is fixedly connected to the top of the inner diameter measuring head 5. A qualified box 14 is fixed to the rear side of the U-shaped seat 2, and a waste box 15 is fixed to the rear side of the U-shaped seat 2.

[0028] During use, when the infrared sensor 11 detects the position of the copper sleeve, the PLC controller activates the guide rail 12, which moves the inner diameter measuring head 5 left and right via the slider to adjust its position so that it is aligned with the copper sleeve, ensuring the accurate positioning of the inner diameter measuring head 5. After the inner diameter of the copper sleeve is detected, qualified copper sleeves are guided by the guide plate 9 to the qualified box 14 for collection, while unqualified copper sleeves are guided to the waste box 15 for unified processing, ensuring the separate collection of qualified and unqualified copper sleeves.

[0029] like Figures 1-4 As shown, the top surface of the U-shaped frame 1 has two limiting holes 16, and the two limiting holes 16 are respectively slidably inserted with limiting posts 17. The bottom ends of the two limiting posts 17 are respectively fixedly connected to the top surface of the guide rail 12. The bottom surfaces of the qualified box 14 and the waste box 15 are respectively fixed with buffer plates 18, and the top surfaces of the two buffer plates 18 are respectively fixed with buffer pads 19.

[0030] During use, the cooperation of the limiting hole 16 and the limiting post 17 helps to limit the guide rail 12, preventing the guide rail 12 and the inner diameter measuring head 5 from deviating during lifting and lowering, thus improving the stability of the guide rail 12 and the inner diameter measuring head 5 during lifting and lowering. The cooperation of the buffer plate 18 and the buffer pad 19 ensures that when the copper sleeve enters the qualified box 14 and the waste box 15, it will first come into contact with the buffer pad 19 on the buffer plate 18, which can effectively absorb the impact force when the copper sleeve falls, preventing the copper sleeve from being damaged or deformed due to impact, thus improving the protective effect of the copper sleeve.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
