Description

[0002] In the field of industrial material handling, the safe and efficient handling of ferromagnetic workpieces is a key link in the production process. Magnetic handling equipment, with its magnetic field adsorption properties for ferromagnetic materials, has formed a unique technical path that is different from traditional mechanical clamping and electromagnetic adsorption. Its core principle is to generate adsorption force through permanent magnets or controllable magnetic circuit structures, so as to grasp the workpiece without physical contact. It is especially suitable for handling ferromagnetic workpieces with easily damaged surfaces, irregular shapes, or large sizes, and provides a lightweight and low-energy solution for industrial automation and material handling.

[0003] However, current magnetic handling equipment generally lacks anti-drop protection structures when handling workpieces after they have been attracted, which poses a risk that the workpieces may fall off the equipment. This problem may cause the workpieces to fall and be damaged, or even lead to equipment failure or personnel safety hazards. In particular, when vibration, unexpected switching of magnetic circuits or magnetic force attenuation occur during the handling process, the workpieces, which lack physical constraints, are prone to falling off due to loss of attraction, making it difficult to meet the higher requirements of industrial scenarios for handling reliability and safety.

[0031] In this embodiment, by Figure 1-6 Presented is a magnetic suction handling device, comprising a horizontally arranged housing 1; a magnetic mechanism 2 disposed within the housing 1 for providing magnetic attraction of workpieces; a slide groove 31 extending along the width direction at the top of the housing 1, the slide groove 31 having a T-shaped structure, two sliders 32 disposed inside the slide groove 31, the sliders 32 being adjustable in position along the length direction of the slide groove 31; a position locking mechanism 3 disposed between the sliders 32 and the slide groove 31 for fixing the position of the sliders 32 within the slide groove 31; hooks 41 are provided on the top of each of the two sliders 32 within the slide groove 31, and a chain 42 passing around the bottom of the housing 1 is connected between the two hooks.

[0032] In this embodiment, the magnetic mechanism 2 generates magnetic force to attract the workpiece 8. At this time, the chain 42 passes around the bottom of the workpiece 8 and connects to the hooks 41 on both sides. Meanwhile, by adjusting the position of the slider 32 in the groove 31, the distance between the hooks 41 on both sides is adjusted so that the chain 42 is taut and fits more closely to the surface of the workpiece 8. At the same time, the position locking mechanism 3 fixes the position of the slider 32 in the groove 31 so that the chain 42 supports the workpiece 8 and provides anti-fall support for the workpiece 8, thus playing a protective role.

[0033] refer to Figure 2 and Figure 5To facilitate the attraction and placement of workpieces, two methods can be used to achieve the desired function: one is to use a magnetic field source with variable magnetic field strength, and the other is to use two magnetic field sources with fixed magnetic field strengths. This involves using magnetic field superposition and cancellation to achieve the attraction and release of the workpiece. However, in this application, since the magnetic handling device is used for manually assisted clamping and handling of small workpieces, it needs to be small in size and simple in structure. Therefore, the second method is preferred. The specific implementation is as follows: Magnetic Mechanism 2 The device includes a limiting member 21, a rotating shaft 22, a second magnetic component 23, and a first magnetic component 24. The first magnetic component 24 is disposed inside the housing 1 and includes at least two magnetic bodies, each of which is connected to the inner wall of the housing 1, and the magnetic poles of adjacent magnetic bodies are opposite. The second magnetic component 23 is disposed below the first magnetic component 24. A rotating shaft 22 is rotatably connected to the outside of the housing, one end of which extends into the inside of the housing 1 and is connected to the second magnetic component 23 to drive the second magnetic component 23 to rotate. The limiting member 21 is disposed on the outside of the housing 1 to limit the rotation position of the rotating shaft 22.

[0034] In this embodiment, the first magnetic component 24 is a fixed magnetic component, consisting of at least two magnetic bodies with their magnetic poles at the top and bottom. The magnetic poles of adjacent magnets are arranged alternately, such as N at the top and S at the bottom, or S at the top and N at the bottom, forming a fixed magnetic circuit. It is fixed inside the housing and serves as the basic magnetic field source. The second magnetic component 23 is a rotatable magnetic component, consisting of a single magnetic body, and is connected to one end of the rotating shaft 22. Therefore, by adjusting the angle (angle of the magnetic poles) of the second magnetic component 23 via the rotating shaft 22, the magnetic field can be switched between a superimposed adsorption state and a canceled release state.

[0035] Superimposed state: Rotate the second magnetic component 23 so that its magnetic pole direction is parallel and in the same direction as the magnetic pole direction of the first magnetic component 24. The magnetic fields of the two are superimposed, the magnetic flux is enhanced, and a strong attraction force is generated. The magnetic force acts on the workpiece 8 through the bottom of the shell 1, so that the workpiece 8 is attracted.

[0036] Cancellation state: Rotate the second magnetic component 23 180° until its magnetic pole direction is parallel to but opposite to the magnetic pole direction of the first magnetic component 24. The magnetic fields cancel each other out, the magnetic flux is greatly reduced, and it is unable to attract the workpiece, causing the workpiece 8 to fall off.

[0037] In the superposition and cancellation states, the limiting member 21 can limit the rotating shaft 22 to ensure that the second magnetic component 23 is stably locked in the adsorption or release position, thus avoiding misoperation.

[0038] refer to Figure 4In one specific embodiment, when the rotating shaft 22 rotates, it can drive the second magnetic component 23 to the adsorption or release position. However, the rotating shaft 22 and the second magnetic component 23 are prone to positional changes under external force, which may cause the workpiece to fall accidentally. To solve the above problem, the adsorption or release position of the rotating shaft 22 is limited by the limiting member 21. Moreover, the limiting member 21 has a simpler structure, lower manufacturing cost, and also has a built-in reset function, making it more convenient to use. The specific implementation method is as follows: The limiting member 21 includes an elastic member 211, a handle 212, a telescopic rod 213, a limiting rod 214, an unlocking rod 215, and a sliding member. The housing 1 has a sliding opening 216 and a spring housing 217. The inner wall of the housing 1 is provided with a spring housing 217. The inside of the spring housing 217 is provided with a telescopic rod 213, one end of which passes through to the side of the rotating shaft 22 connected to the housing 1. The inner wall of the spring housing 217 is provided with an elastic element 211, the other end of which is connected to the other end of the telescopic rod 213. Two limiting rods 214 are provided at intervals on both sides of the rotating shaft 22 on the side of the housing 1 through which the telescopic rod 213 passes. The inner wall of the housing 1 is provided with a sliding opening 216. The telescopic rod 213 is provided with an unlocking rod 215 that passes through the sliding opening 216. The outer side of the rotating shaft 22 is provided with a handle 212.

[0039] In this embodiment, there are two limiting rods 214, located on both sides of the rotating shaft 22. Both limiting rods 214 are also located below the telescopic rod 213. The elastic element 211 provides elastic force to the telescopic rod 213, allowing it to extend and retract. Therefore, in the adsorption position, the handle 212 on the rotating shaft 22 is positioned between the telescopic rod 213 and the adjacent limiting rod 214, acting as a limit to ensure that the second magnetic component 23 is always in the adsorption position. In the release position, when the handle 212 on the rotating shaft 22 rotates 180 degrees about the rotating shaft 22 as the axis of rotation, the handle 212 will abut against the other limiting rod 214, acting as a limit to prevent the second magnetic component 23 from rotating excessively. This ensures that the second magnetic component 23 is stably in the release state, preventing accidental adsorption of the workpiece.

[0040] It should be noted that the elastic element 211 is a spring. When it is necessary to rotate the shaft 22 to switch the position of the second magnetic component 23, the operator manually pulls the unlocking lever 215. The unlocking lever 215 drives the telescopic lever 213 to overcome the elastic force of the elastic element 211 and slide along the spring shell 217 towards the inside of the housing 1, causing the telescopic lever 213 to disengage from the handle 212. At this time, the shaft 22 loses its limiting constraint, and the operator can drive the shaft 22 to rotate through the handle 212, thereby driving the second magnetic component 23 to rotate from the adsorption position to the release position.

[0041] In addition, the end of the telescopic rod 213 away from the elastic element 211 is provided with a slope, for reference. Figure 4When the handle 212 swings toward the unlocking lever 215, it can push the telescopic lever 213 along the inclined surface so that the telescopic lever 213 avoids the handle 212. After the handle 212 passes the telescopic lever 213, it is then reset under the action of the spring, so that the handle 212 is quickly placed between the limiting lever 214 and the telescopic lever 213, which is more convenient.

[0042] refer to Figure 6 In one specific embodiment, since both ends of the chain 42 are connected to the slider 32 via hooks 41, in order to keep the chain 42 taut and fully contact the bottom of the workpiece 8, it is necessary to fix the slider 32 after position adjustment. To solve the above problem, in this embodiment, the slider 32 is positioned by means of a hole-fitting pin. Compared with other positioning methods, this method is faster, simpler in structure, and lower in manufacturing cost. The specific implementation method is as follows: The position locking mechanism 3 includes a positioning hole 33, a positioning fitting hole 34, and a positioning pin 35. The inner top wall of the slide groove 31 is provided with a positioning hole group arranged along the length direction. The positioning hole group includes multiple positioning holes 33. The top of the slider 32 is provided with a positioning fitting hole 34. The positioning pin 35 passes through the positioning fitting hole 34, and one end of the positioning pin 35 can be selectively inserted into any one of the positioning holes 33 in the positioning hole group to fix the position of the slider 32 in the slide groove 31.

[0043] In this embodiment, when the chain 42 is taut and in full contact with the bottom of the workpiece 8, the positioning pin 35 passes through the corresponding positioning hole 33 and positioning mating hole 34 to limit the slider 32, so that the hook 41 on the slider 32 pulls one end of the chain 42, keeping the chain 42 taut and in full contact with the bottom of the workpiece 8, thereby improving the anti-drop effect.

[0044] In addition, there are two sets of positioning holes, which are respectively placed on both sides of the inner top wall of the slide 31. The inner bottom wall of the slide 31 is provided with two sets of slots that correspond to the two sets of positioning holes. The slots include multiple slots 5 arranged along the length direction, and the multiple slots 5 correspond one-to-one with the multiple positioning holes 33 in the positioning hole set. There are two positioning mating holes 34, which are arranged at intervals.

[0045] There are two sets of positioning holes, and two positioning mating holes 34. Therefore, two positioning pins 35 can be used to position the same slider 32, resulting in better positioning. Secondly, the slot 5 is set in the bottom wall of the slide groove 31. Therefore, after the positioning pin 35 passes through the positioning mating hole 34 on the slider 32, it can enter the slot 5. Through the double constraint of "top wall positioning hole + bottom wall slot", the slider 32 is fixed in a specific position in the slide groove 31. When the slider 32 bears the suspension load of the workpiece, the load is transferred to the top and bottom walls of the slide groove 31 through the positioning pin 35. As a support structure of the bottom wall, the slot 5 can share the shear force and bending moment of the positioning pin 35, avoiding structural fatigue or damage caused by relying solely on the top wall positioning hole 33 for bearing.

[0046] Furthermore, the inner wall of the positioning hole 33 is provided with an internal thread, and one end of the positioning pin 35 is provided with an external thread that matches the internal thread.

[0047] Through the threaded engagement, the positioning pin 35 and the positioning hole 33 form a mechanical lock, which is less likely to loosen due to vibration, external force or long-term use, and ensures that the slider 32 is reliably fixed in the groove 31.

[0048] Both ends of the slide 31 are provided with limit seats 6 to limit the slider 32.

[0049] To prevent the slider 32 from sliding excessively within the slide groove 31 and dislodging from it, this ensures that the slider 32 always runs within the preset track, preventing the conveying device from malfunctioning or the workpiece from falling due to the slider 32 detaching.

[0050] The top of the housing 1 is provided with a lifting ring 7.

[0051] The lifting ring 7 is the direct chain between the equipment and external lifting equipment such as wire ropes and hooks. Through the lifting ring 7, the equipment can be suspended below the lifting equipment, and the lifting power of the lifting equipment can be used to vertically lift and transport the workpiece.

[0052] Working principle: The distance between the hooks 41 on both sides is adjusted by the slider 32 in the top groove 31 of the housing 1, so that the chain 42 passing around the bottom of the workpiece 8 is tightened and attached to the surface of the workpiece 8 to support the workpiece 8 to prevent it from falling off. The positioning pin 35 of the position locking mechanism 3 passes through the positioning hole 34 of the slider 32 and forms a double lock with the positioning hole 33 on the top wall of the groove 31 and the slot 5 on the bottom wall. The thread engagement of the internal thread of the positioning hole 33 and the external thread of the positioning pin 35 enhances the fixing reliability.

[0053] In addition, the first magnetic component 24 fixed in the housing 1 of the magnetic mechanism 2 is composed of a basic magnetic circuit consisting of at least two magnetic bodies with alternating magnetic poles. The outer rotating shaft 22 drives the lower rotatable second magnetic component 23 to rotate. When the magnetic poles of the second magnetic component 23 are parallel to the first magnetic component 24 in the same direction, the magnetic field superimposes to generate a strong adsorption force to adsorb the workpiece 8. When they are parallel in opposite directions, the magnetic field cancels out the magnetic force and releases the workpiece 8. During this period, the telescopic rod 213 is extended and retracted through the elastic element 211, so that the handle 212 can be placed between a limit rod 214 and the telescopic rod 213 or against another limit rod 214. The handle 212 is connected to the rotating shaft 22. Therefore, the rotating shaft 22 can be locked and switched between the adsorption position and the release position. The lifting ring 7 is connected to the lifting equipment to realize the lifting and transportation of the device.
