An anti-stick electromagnetic suction head device

Abstract

This utility model discloses an anti-sticking electromagnetic suction head device, relating to the field of magnetic suction handling technology. Specifically, it includes a lifting plate, an electromagnet, and a side plate. The electromagnet is slidably connected to the lifting plate, with its side away from the lifting plate serving as the suction surface. The side plate is connected to the lifting plate and extends towards the electromagnet. When the electromagnet moves towards the lifting plate, its suction surface can move to a position between the end face of the side plate and the lifting plate, allowing the workpiece to be detached from the electromagnet's suction surface through the end face of the side plate. The electromagnet attracts and transports the workpiece. When the electromagnet is demagnetized, and its remaining magnetic force still attracts, the electromagnet retracts inward, causing the side plate to contact the workpiece on the electromagnet's suction surface, thus detaching the workpiece from the electromagnet's suction surface and preventing secondary attraction of the workpiece.

Description

Technical Field

[0001] This utility model relates to the field of magnetic suction handling technology, and in particular to an anti-stick electromagnetic suction head device. Background Technology

[0002] In the existing field of workpiece handling technology, electromagnetic chucks are used to handle workpieces. The working principle of these electromagnetic chucks is that when an internal coil is energized, a magnetic field is generated. The magnetic lines of force are conducted through the magnetically conductive panel and form a closed loop with the ferromagnetic material, thereby creating an attraction force to attract the workpiece. When the power is turned off, theoretically the magnetic force should disappear, thus releasing the workpiece.

[0003] However, existing electromagnets that generate magnetism when energized have significant technical drawbacks. After power is cut off, the electromagnet's suction head cannot completely eliminate the magnetism, leaving a residual force. This residual magnetism continues to attract the workpiece after the handling process is complete, and when the workpiece is lightweight, secondary attraction can easily occur. This not only affects handling efficiency but also leads to collisions between workpieces in the next work cycle. These collisions can further trigger a series of quality problems, such as cracks and chips, severely impacting the reliability and stability of workpiece handling and subsequent production processes.

[0004] Therefore, this application aims to solve the problem that the residual magnetism of the electromagnetic chuck can attract the workpiece a second time. Utility Model Content

[0005] The main purpose of this invention is to provide an anti-stick electromagnetic suction head device, which aims to optimize the structure of the electromagnetic suction head, avoid secondary adsorption of workpieces by residual magnetism, and also avoid collisions between workpieces in different work cycles.

[0006] To achieve the above objectives, this utility model proposes an anti-stick electromagnetic suction head device, comprising:

[0007] lift board;

[0008] An electromagnet is slidably connected to the lifting plate, with its side away from the lifting plate serving as an adsorption surface;

[0009] A side plate, connected to the lifting plate, extends toward the electromagnet;

[0010] When the electromagnet moves toward the lifting plate, its adsorption surface can move to the space between the end face of the side plate and the lifting plate, so as to peel the workpiece from the adsorption surface of the electromagnet through the end face of the side plate.

[0011] Furthermore, the side plate is installed on one side or opposite sides of the lifting plate.

[0012] Furthermore, the end face of the side plate is provided with at least one guide groove.

[0013] Furthermore, the workpiece has a circular cross-section, and when the workpiece is attracted to the electromagnet, the end of the workpiece is restricted at the guide groove.

[0014] Furthermore, an mounting plate is fixedly installed on the side of the electromagnet facing the lifting plate. The mounting plate is slidably connected to the lifting plate and synchronously drives the electromagnet to slide with the lifting plate.

[0015] Furthermore, the lifting plate is provided with an elastic element, which applies a reaction force to the mounting plate when the electromagnet approaches the lifting plate.

[0016] Furthermore, the elastic element is disposed between the lifting plate and the mounting plate.

[0017] Furthermore, it includes a first telescopic cylinder and a second telescopic cylinder. The output shaft of the first telescopic cylinder is connected to the lifting plate, and the second telescopic cylinder is fixed on the lifting plate, with its output shaft passing through the lifting plate and connected to the mounting plate.

[0018] Furthermore, a top plate is connected to the top of the lifting plate, and a positioning plate is connected to the output end of the first telescopic cylinder. The top plate and the positioning plate are in the same vertical direction, and a threaded hole is provided in the middle of the top plate.

[0019] Furthermore, it includes a bracket, a movable module, and a fixed plate. The movable module is disposed on the bracket, one side of the fixed plate is connected to the first telescopic cylinder, and the other side of the fixed plate is fixed to the output end of the movable module.

[0020] The above technical solution has the following advantages:

[0021] This application provides side plates around the electromagnet. When the electromagnet attracts a workpiece, it moves the workpiece from a first position to a second position until the electromagnet is demagnetized. However, the residual magnetic force of the electromagnet still attracts the workpiece. This application causes the electromagnet to retract inward and uses the side plates to abut and peel off the workpiece, avoiding secondary attraction of the workpiece under the residual magnetism of the electromagnet, and also preventing collision and cracking with the workpiece to be transported in the next cycle after secondary attraction.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0028] like Figure 2 As shown, an anti-stick electromagnetic suction head device includes a lifting plate 5, an electromagnet 8, and a side plate 9. The electromagnet 8 is slidably connected to the lifting plate 5, with its side away from the lifting plate 5 serving as the adsorption surface. The side plate 9 is connected to the lifting plate 5 and extends towards the electromagnet 8. When the electromagnet 8 moves towards the lifting plate 5, its adsorption surface can move to the space between the end face of the side plate 9 and the lifting plate 5, allowing the workpiece 10 to be peeled off from the adsorption surface of the electromagnet 8 through the end face of the side plate 9. The electromagnet 8 is connected by a wire to generate magnetic adsorption, and its adsorption surface is used to adsorb the workpiece 10, facilitating the transfer of the workpiece 10 to different positions via adsorption. The side plate 9 is fixed to the lifting plate 5. When the electromagnet 8 is energized and adsorbs the workpiece 10, it moves towards the lifting plate 5, gradually bringing the workpiece 10 closer to the side plate 9. The end face of the side plate 9 abuts against the edge of the workpiece 10, thereby peeling the workpiece 10 off the electromagnet 8 and preventing the workpiece 10 from being re-adsorbed onto the electromagnet 8 after it is demagnetized.

[0029] like Figure 2 As shown, in this application, the side plate 9 is installed on one side or opposite sides of the lifting plate 5. If the side plate 9 is installed on one side of the lifting plate 5, it is only suitable for workpieces 10 with shorter length. In order to improve the applicability, this application preferably installs the side plate 9 on both opposite sides of the lifting plate 5, which helps to peel off both ends of the workpiece 10 at the same time through the side plates 9 on both sides, thereby improving the detachment effect of the workpiece 10.

[0030] like Figure 2 and Figure 3As shown, in this application, the end face of the side plate 9 is provided with at least one guide groove 12. The guide groove 12 can be designed to mimic the cross-section of the workpiece 10. For example, if the cross-section of the workpiece 10 is square or polygonal, the guide groove 12 can be flat or square. In this application, the cross-section of the workpiece 10 is circular. When the workpiece 10 is attracted to the electromagnet 8, the end of the workpiece 10 is restricted at the guide groove 12. The cross-section of the guide groove 12 is arc-shaped. Preferably, four sets are provided, which can attract and transport multiple workpieces 10 at a time, thereby improving the transport efficiency of the workpiece 10.

[0031] like Figure 2 As shown, an installation plate 7 is fixedly mounted on the side of the electromagnet 8 facing the lifting plate 5. The installation plate 7 is slidably connected to the lifting plate 5 and synchronously drives the electromagnet 8 to slide with the lifting plate 5. The electromagnet 8 is mounted on one side of the installation plate 7, which facilitates wiring of the electromagnet 8. An elastic element 11 is provided on the lifting plate 5. When the electromagnet 8 approaches the lifting plate 5, the elastic element 11 applies a reaction force to the installation plate 7. At the same time, when the installation plate 7 and the electromagnet 8 approach the lifting plate 5 simultaneously, the elastic element 11 will resist the installation plate 7, thereby restricting the installation plate 7 from continuing to move towards the lifting plate 5. This process can improve the protective effect of the workpiece 10 after placement, avoiding the risk of the workpiece 10 breaking due to excessive pressure caused by its own weight, and playing a good buffering role.

[0032] In this application, the elastic element 11 is disposed between the lifting plate 5 and the mounting plate 7 to limit the distance between the mounting plate 7 and the lifting plate 5. The elastic element 11 can be made of materials such as springs, sheet metal, or rubber blocks, and only needs to be placed between the lifting plate 5 and the mounting plate 7. In this application, a number of guide posts are provided on the mounting plate 7. The guide posts pass through the lifting plate 5 and are slidably connected to the lifting plate 5. The springs are preferably disposed on the periphery of the guide posts.

[0033] like Figure 2 As shown, this application also includes a first telescopic cylinder 4 and a second telescopic cylinder 6. The output shaft of the first telescopic cylinder 4 is connected to the lifting plate 5, and the second telescopic cylinder 6 is fixed on the lifting plate 5. Its output shaft passes through the lifting plate 5 and is connected to the mounting plate 7. The output end of the first telescopic cylinder 4 drives the lifting plate 5 to move up and down, thereby driving the electromagnet 8 to move closer to or away from the workpiece 10. The output end of the second telescopic cylinder 6 drives the mounting plate 7 to move closer to or away from the workpiece 10. The combination of the first telescopic cylinder 4 and the second telescopic cylinder 6 can realize coarse movement and fine adjustment, which greatly improves the handling efficiency of the workpiece 10, and at the same time avoids the instability of the placement or adsorption of the workpiece 10.

[0034] like Figure 2As shown, the top of the lifting plate 5 is also connected to the top plate 13, and the output end of the first telescopic cylinder 4 is connected to the positioning plate 14. The top plate 13 and the positioning plate 14 are in the same vertical direction. A threaded hole is provided in the middle of the top plate 13, in which a screw can be inserted, so that one end of the screw is rotatably connected to the positioning plate 14. The outer wall of the screw is threadedly driven by the threaded hole, thereby driving the height adjustment of the top plate 13, and then driving the lifting plate 5 to achieve height adjustment, which helps to make fine adjustments for workpieces 10 of different heights.

[0035] like Figure 1 and Figure 2 As shown, this application includes a support 1, a movable module 2, and a fixed plate 3. The movable module 2 is mounted on the support 1. One side of the fixed plate 3 is connected to the first telescopic cylinder 4, and the other side of the fixed plate 3 is fixed to the output end of the movable module 2. The movable module 2 is installed at the top of the support 1 and includes a motor, a flexible component, and a drive wheel. The motor and drive wheel drive the flexible component to move. The fixed plate 3 is fixed to the flexible component in the movable module 2, thereby driving the fixed plate 3 to adjust back and forth to realize the handling operation. The flexible component is preferably a belt or chain. A slide rail can also be provided at the top of the support 1 so that the fixed plate 3 can move along the slide rail, which can greatly reduce the load on the flexible component and improve the stability of the transmission.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
