Description

Technical Field

[0001] This application belongs to the field of magnetic attraction equipment technology, and in particular relates to a magnetic attraction transport device with a pin shaft. Background Technology

[0002] In the field of mechanical manufacturing, metal workpieces are usually moved by magnetic attraction. Existing commonly used magnetic attraction equipment generally uses two methods: electro-permanent magnets and traditional electromagnets. However, electro-permanent magnets have high manufacturing costs, large size, and poor overall equipment flexibility. While traditional electromagnets have the advantages of low cost, small size, and customizability, they have the fatal flaw of losing magnetism immediately when the power is cut off, which makes the workpiece easy to fall and poses a safety hazard. They cannot meet the safety and stability requirements of industrial production, so improvements are needed. Utility Model Content

[0003] The purpose of this application is to address the aforementioned technical problems by providing a magnetic handling device for a pin shaft, which can improve the safety and stability of handling via electromagnets.

[0004] This application provides a magnetic conveying device for a pin, comprising: A magnetic attraction device includes an electromagnet and a control switch, wherein the electromagnet and the control switch are connected by a wire; Connector, attached to the magnetic attraction device; A sling assembly includes a hook, a chain, and a handle, wherein the handle is positioned between the hook and the chain; The power failure protection device includes a battery pack, a dual power switching module, an input terminal, an output terminal, and a rectifier; The control switch is mounted on the connector, the dual power switching module is connected to the battery pack, the rectifier is connected between the dual power switching module and the input terminal, a charger is connected between the battery pack and the input terminal, the dual power switching module is connected to the output terminal, the output terminal is connected to the control switch, and the electromagnet is provided with an adsorption surface.

[0005] A conventional electromagnet is a physical device composed of a magnetic core and a coil. It generates a magnetic field using the magnetic effect of electric current, and its magnetism can be controlled by switching the current on and off. When the electromagnet is energized, it produces a magnetic attraction. The energization of the electromagnet is controlled by a switch, making it easy to use. A connector is mounted on the electromagnet, and the control switch is connected to the connector via a threaded connection or fastener. The connector is made of sheet metal. When in use, the magnetic attraction device is hung on a hook via the connector. The hook, handle, and chain are connected in sequence. The handle facilitates gripping and use, and the chain has high structural strength, capable of lifting heavy metal objects. The electromagnet only has a magnetic attraction when energized. A 220V AC power supply is provided through the input terminal, which is converted to 24V DC power by a rectifier to continuously supply power to the electromagnet, enabling the magnetic attraction device to function. The device maintains its magnetic attraction. When the input suddenly loses power, the dual power switching module automatically switches to battery power until the mains power is restored. The battery pack is a 24V rated lithium iron phosphate battery pack with a rated capacity of 15AH. Through the dual power switching module and the battery pack, continuous power supply can be achieved during mains power outages, ensuring the magnetic stability of the magnetic attraction device, preventing metal parts from falling off the magnetic attraction device, and further improving the safety performance of the magnetic attraction device. When the input provides 220V AC power, a charger is connected between the battery pack and the input to charge the battery pack. The charger is a 29.2V rated lithium battery charger with a rated current of 2.4A. The electromagnet abuts against the metal parts through the adsorption surface, which is located on the lower side of the electromagnet.

[0006] Using electromagnets to magnetically attract metal parts for handling has a lower procurement cost compared to electro-permanent magnets, and the power failure protection device can prevent the workpiece from falling when the power is off, ensuring production safety.

[0007] Furthermore, the power failure protection device also includes: An emergency stop switch is connected between the output terminal and the dual power supply switching module.

[0008] Furthermore, the power failure protection device also includes: Main power indicator light, connected to the dual power switching module; The auxiliary power indicator light is connected to the dual power switching module.

[0009] Furthermore, the adsorption surface is planar.

[0010] Furthermore, the adsorption surface is V-shaped.

[0011] Furthermore, the connector includes: The connecting parts are respectively located on both sides of the connector, and the connecting parts are connected to the electromagnet.

[0012] Furthermore, the sling assembly also includes: A winding device for winding up the chain; A sensor controller is connected between the handle and the chain. The sensor controller is equipped with a display screen for displaying the weight being transported and a first sensor.

[0013] Furthermore, the handle includes: A shaft is used to connect the hook and the sensor controller, and the handle is movably connected to the shaft. The active part is located at one end of the handle and is placed in the sensor controller; A reset spring is placed in the movable part and the sensing controller, with the reset spring located on both sides of the movable part; The second sensor is placed in the sensing controller and corresponds to both sides of the moving part.

[0014] This application also provides a method for handling a pin using a magnetic attraction handling device, the specific steps of which include: S1, by moving the handle downward relative to the shaft, the magnetic suction device is controlled to move downward, so that the adsorption surface of the magnetic suction device is engaged with the metal part to be attracted. By controlling the switch, the magnetic suction device is powered on to magnetically attract the metal part. By moving the handle upward relative to the shaft, the magnetic suction device is controlled to move upward, so that the metal part is lifted. S2, move the suspended metal part and magnetic suction device above the placement position, move the handle downward relative to the shaft to control the magnetic suction device to move downward, place the metal part in the placement position, and turn off the power to the magnetic suction device by controlling the switch to separate the magnetic suction device from the metal part.

[0015] After the metal part is magnetically attracted by the magnetic attraction device, the handle is moved upward to control the winding device to wind up the chain, thereby lifting the magnetic attraction device and the metal part upward. Then, the magnetic attraction device is moved horizontally above the placement position by a movable cantilever or gantry structure. Then, the handle is moved downward to control the winding device to unwind the chain, thereby moving the magnetic attraction device and the metal part downward and placing them in the corresponding position. The electromagnet is de-energized by the control switch to release the magnetic attraction and separate the metal part from the electromagnet.

[0016] The beneficial effects of this application are: 1. The magnetic attraction device uses an electromagnet to generate magnetic attraction when energized, thus achieving magnetic attraction of metal parts. Electromagnets are small in size and low in cost, reducing procurement costs.

[0017] 2. By using a battery pack as a secondary power source, it can provide power during power outages, which can solve the problem of workpieces falling due to loss of magnetism after power failure of traditional electromagnets, thus improving safety performance.

[0018] 3. The dual power supply switching module enables rapid switching during power outages, ensuring continuous power supply to the electromagnet and improving safety performance.

[0019] 4. The electromagnet can be configured with planar or V-shaped adsorption surfaces to adapt to workpieces of different shapes and meet different weight requirements. Attached Figure Description

[0023] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0024] Example 1: like Figure 1 , Figure 2 As shown, this application embodiment provides a magnetic conveying device for a pin, including: The magnetic attraction device 100 includes an electromagnet 110 and a control switch 120, wherein the electromagnet 110 and the control switch 120 are connected by a wire; Connector 200 is connected to magnetic suction device 100; The sling assembly 300 includes a hook 310, a chain 330, and a handle 320, wherein the handle 320 is positioned between the hook 310 and the chain 330. The power failure protection device 400 includes a battery pack 410, a dual power switching module 420, an input terminal 430, an output terminal 440, and a rectifier 450. The control switch 120 is mounted on the connector 200, the dual power switching module 420 is connected to the battery pack 410, the rectifier 450 is connected between the dual power switching module 420 and the input terminal 430, the charger 460 is connected between the battery pack 410 and the input terminal 430, the dual power switching module 420 is connected to the output terminal 440, the output terminal 440 is connected to the control switch 120, and the electromagnet 110 is provided with an adsorption surface 111.

[0025] The conventional electromagnet 110 is a physical device composed of a magnetic core and a coil. It generates a magnetic field using the magnetic effect of electric current, and its magnetism can be controlled by switching the current on and off. When the electromagnet 110 is energized, it generates a magnetic attraction. The energization of the electromagnet 110 is controlled by a control switch 120 for ease of use. A connector 200 is installed on the electromagnet 110, and the control switch 120 is connected to the connector 200 via a threaded connection or fastener. The connector 200 is made of sheet metal. When in use, the magnetic attraction device 100 is hung on the hook 310 via the connector 200. The hook 310, handle 320, and chain 330 are connected in sequence. The handle 320 facilitates gripping and use, and the chain 330 has high structural strength and can lift heavy metal parts. The electromagnet 110 only has a magnetic attraction when energized. 220V AC power is provided through the input terminal 430, which is converted into 24V DC power by the rectifier 450 to continuously supply power to the electromagnet 110, enabling the magnetic attraction device 100 to function. The magnetic attraction is maintained. When the input terminal 430 suddenly loses power, the dual power switching module 420 automatically switches to power the battery pack 410 until the mains power is restored to the input terminal 430. The battery pack 410 is a lithium iron phosphate battery pack with a rated voltage of 24V and a rated capacity of 15AH. Through the dual power switching module 420 and the battery pack 410, continuous power supply can be achieved when the mains power fails, ensuring the magnetic attraction stability of the magnetic attraction device 100, preventing the metal parts from falling off the magnetic attraction device 100, and further improving the safety performance of the magnetic attraction device 100.

The charger 460 is a lithium battery charger with a rated voltage of 29.2V and a rated current of 2.4A. The electromagnet 110 abuts against the metal parts through the adsorption surface 111, which is located on the lower side of the electromagnet 110.

[0026] Using an electromagnet 110 to magnetically attract metal parts for handling has a lower procurement cost compared to electro-permanent magnets, and the power failure protection device 400 can prevent the workpiece from falling when the power is off, thus ensuring production safety.

[0027] Furthermore, the power failure protection device 400 also includes: Emergency stop switch 470 is connected between output terminal 440 and dual power supply switching module 420.

[0028] The emergency stop switch 470 is installed on the power failure protection device 400. The emergency stop switch 470 can control the power supply of the output terminal 440 to stop in an emergency.

[0030] The main power indicator 480 and the auxiliary power indicator 490 are installed on the power failure protection device 400. When the input terminal 430 is powered, the main power indicator 480 is lit. When the input terminal 430 stops supplying power, the power is switched to the battery pack 410 through the dual power switching module 420. At this time, the auxiliary power indicator 490 is lit. The power supply status of the magnetic device 100 can be easily confirmed by the on / off status of the main power indicator 480 and the auxiliary power indicator 490.

[0031] Example 2: like Figure 3 As shown, this application embodiment provides a magnetic conveying device for a pin shaft. In addition to the above-mentioned technical features, the adsorption surface 111 is planar.

[0032] When the adsorption surface 111 is planar, it facilitates the handling of metal sheets. The adsorption surface 111 has a large contact area with the metal sheet, which improves the magnetic attraction effect.

[0033] Example 3: like Figure 4 As shown, this application embodiment provides a magnetic conveying device for a pin shaft. In addition to the above-mentioned technical features, the adsorption surface 111 is V-shaped.

[0034] When the adsorption surface 111 is V-shaped, it facilitates the handling of metal round rod shafts. The V-shaped adsorption surface 111 can be applied to rods of different specifications and sizes.

[0035] Example 4: like Figure 1 , Figure 3 , Figure 4 As shown, this application embodiment provides a magnetic conveying device for a pin, which, in addition to the above-mentioned technical features, further includes the following: The connecting parts 210 are respectively placed on both sides of the connector 200, and the connecting parts 210 are connected to the electromagnet 110.

[0036] The connector 200 is made of sheet metal, and the connecting part 210 is formed by sheet metal processing. The connecting part 210 is bent to both sides of the connector 200, which can improve the stability of the connector 200 after installation. The connecting part 210 facilitates the welding or fastening of the connector 200 and the electromagnet 110. The connector 200 also has mounting holes for installing the control switch 120 and hanging holes for hanging the hook 310.

[0037] Example 5: like Figure 1 , Figure 5 As shown, this application embodiment provides a magnetic conveying device for a pin, which, in addition to the above-mentioned technical features, further includes the following: A winding device 340 is used to wind up the chain 330; A sensor controller 500 is connected between the handle 320 and the chain 330. The sensor controller 500 is equipped with a display screen 510 for displaying the weight being transported, and a first sensor 520.

[0038] The winding device 340 mainly uses a winch to wind up the chain 330. The winch is driven by a motor to rotate, thereby realizing the lifting and lowering of the magnetic attraction device 100 suspended on the hook. The induction controller 500 is connected between the handle 320 and the chain 330. When the magnetic attraction device 100 magnetically attracts a metal part and is suspended, the induction controller 500 has a control board for collecting, analyzing and calculating. The weight of the magnetically attracted metal part can be detected by the first sensor 520 on the induction controller 500 and displayed on the display screen 510. The first sensor 520 is a pressure sensor.

[0039] The winding device 340 is mounted on a gantry or cantilever arm. The gantry or cantilever arm has a slide rail, and the winding device 340 has a slider seat or roller that is compatible with the slide rail. The movement of the winding device 340 on the slide rail can be driven by a direct cable chain 330 or by a motor screw or other structure, which can realize the horizontal movement of the magnetic suction device 100.

[0040] Furthermore, the handle 320 includes: The shaft 600 is used to connect the hook 310 and the sensor controller 500, and the handle 320 is movably connected to the shaft 600; The movable part 321 is located at one end of the handle 320 and is placed in the sensor controller 500; A reset spring 530 is placed in the movable part 321 and the sensing controller 500, and the reset spring 530 is placed on both sides of the movable part 321; The second sensor 540 is placed in the sensing controller 500 and corresponds to both sides of the moving part 321.

[0041] The shaft 600 is mounted on the induction controller 500 and abuts against the first sensor 520. When the shaft 600 receives a downward pulling force, it acts on the first sensor 520, enabling the first sensor 520 to detect the sensor. The handle 320 is movably connected to the shaft 600, and the movable part 321 enables the movable connection between the handle 320 and the induction controller 500. When the handle 320 moves away from the induction controller 500, i.e., moves downward, it abuts against the corresponding second sensor 540 below it through the movable part 321. The corresponding second sensor 540 detects the signal and transmits it to the induction controller 500, controlling the winding device 340 to unwind the chain 330, thus moving the magnetic suction device 100 downward. When the handle 320 moves closer to the sensor... When the controller 500 moves in the direction of upward movement, the movable part 321 abuts against the corresponding second sensor 540 above it. The corresponding second sensor 540 detects the signal and transmits it to the induction controller 500, controlling the winding device 340 to wind up the chain 330, thereby moving the magnetic suction device 100 upward. When the user holds the handle 320, the handle 320 moves along the axis of the shaft 600, adjusting the magnetic suction device 100 to move upward or downward. When the user holds the handle 320, the upward or downward movement of the handle 320 is released, causing the movable part 321 to separate from the second sensor 540, the winding device 340 to stop working, and the height position of the magnetic suction device 100 does not change. The second sensor 540 is a pressure sensor or an infrared sensor, etc.

[0042] Example 6: This application also provides a method for handling a pin using a magnetic attraction handling device, the specific steps of which include: S1, by moving the handle 320 downward relative to the shaft 600, the magnetic suction device 100 is controlled to move downward, so that the suction surface 111 of the magnetic suction device 100 is engaged with the metal part to be suctioned. By controlling the switch 120, the magnetic suction device 100 is powered on to magnetically suction the metal part. By moving the handle 320 upward relative to the shaft 600, the magnetic suction device 100 is controlled to move upward, so that the metal part is lifted. S2, move the suspended metal part and magnetic suction device 100 to above the placement position, move the handle 320 downward relative to the shaft 600 to control the magnetic suction device 100 to move downward and place the metal part in the placement position, and turn off the power to the magnetic suction device 100 by controlling the switch 120 to separate the magnetic suction device 100 from the metal part.

[0043] After the metal part is magnetically attracted by the magnetic attraction device 100, the handle 320 is moved upward to control the winding device 340 to wind up the chain 330, thereby lifting the magnetic attraction device 100 and the metal part upward. Then, the magnetic attraction device 100 is moved horizontally above the placement position by a movable cantilever or gantry structure. Then, the handle 320 is moved downward to control the winding device 340 to unwind the chain 330, thereby moving the magnetic attraction device 100 and the metal part downward and placing them in the corresponding position. The electromagnet 110 is de-energized by the control switch 120 to release the magnetic attraction and separate the metal part from the electromagnet 110.
