[0002] The maglev conveyor system is an advanced technology that realizes contactless transportation based on electromagnetic force or permanent magnet interaction. Its core principle is to eliminate the frictional losses caused by traditional mechanical contact through an active or passive levitation mechanism, thereby breaking through the limitations of speed, energy efficiency, and wear.

[0003] In the patent with the publication number CN211687379U, a maglev production conveyor line and a battery cell assembly production system are disclosed. The maglev production conveyor line includes a suspension guide rail, a maglev mover, a maglev stator, and a suspension tray. The suspension tray is arranged on the maglev mover. The maglev stator is arranged at the bottom of the suspension guide rail along the extension direction of the suspension guide rail. The maglev mover is movably arranged on the suspension guide rail and is located above the maglev stator, and is used to move along the suspension guide rail under the drive of the maglev stator. Compared with the prior art, the provided maglev production conveyor line realizes the transportation of battery cells through the maglev principle, which is fast and accurate, can quickly transport the battery cells to the predetermined position, has a high speed and high precision, and greatly improves the efficiency of the production line; During the actual use of the device, the force exerted by the stator assembly on the mover assembly is mainly controlled by changing the direction and magnitude of the current in the stator assembly, and the magnitude and direction of the current flowing in the stator assembly are mainly controlled by the corresponding control system. During use, it may lose control of the mover platen due to factors such as voltage fluctuations (voltage dips or momentary power outages: insufficient magnetic field strength, the rotor loses levitation force or driving force), etc., and then the mover platens may collide with each other, resulting in deformation and wear of the mover platens, affecting the service life of the device; Therefore, the present solution proposes a discontinuous maglev conveyor system to solve the above problems.

DETAILED DESCRIPTION OF THE EMBODIMENTS

For example, the front and the rear are based on Figure 1 as the standard. Specifically, the Figure 1 left side of the Figure 1 is the front, and the Figure 2 right side is the rear; at the same time, as shown in

[0019] Referring to Figures 1-9 as shown, the present invention provides a discontinuous magnetic levitation conveying system, which includes a module base 1. A slide rail 3 is arranged on the top surface of the module base 1. A moving block 2 is slidably arranged on the slide rail 3. A buffer assembly 6 is cooperatively installed in the moving block 2. A resistance member 9 is arranged between the buffer assembly 6 and the moving block 2; The buffer assembly 6 includes a moving plate 604. Installation cavities 10 are symmetrically opened in the module base 1. The moving plate 604 is slidably arranged in the installation cavities 10. Plastic plates 605 are symmetrically installed on the end faces of the moving plate 604. A first copper sheet 606 is respectively embedded in each of the two plastic plates 605; Installation grooves 5 are symmetrically opened on the left and right sides of the moving block 2 respectively. Iron cores 601 are installed in the installation grooves 5. Coils 602 are wound on the outer walls of the iron cores 601. The coils 602 penetrate through the inner walls of the installation grooves 5 and extend into the interior of the installation cavities 10 and are connected to a third copper sheet 609; Plastic blocks 603 are symmetrically installed on the top surface of the inner cavity of the installation cavity 10 and close to one side of the buffer assembly 6. The third copper sheet 609 is embedded in the interior of the plastic blocks 603. Storage batteries 608 are symmetrically installed on the bottom surfaces of the two installation cavities 10 and close to each other. A second copper sheet 607 is installed at the power output end of the storage battery 608. The second copper sheet 607 is horizontally arranged.

[0020] In a further embodiment, referring to Figures 1-9 , an isolation frame 7 is installed above the side wall of the inner cavity of the installation cavity 10. A fixing cavity 12 is opened on the moving block 2. A mover magnet 4 is installed in the fixing cavity 12; an inner cavity is arranged in the slide rail 3. A stator 11 is discontinuously arranged in the slide rail 3; Among them, the stator 11 is connected to an external power supply and is provided with a control device for controlling it. The control principle and function of the control device and the stator 11 are the same as those of the control system in a prior art assembly line with a magnetic levitation structure (publication number: CN216996678U), and will not be elaborated here.

[0021] In a further embodiment, referring to Figures 1-9 , the resistance member 9 includes a connecting frame 901. The connecting frame 901 is installed below the inner cavity side wall of the installation cavity 10, and installation slots two 902 are respectively formed at the four corners of the connecting frame 901; Four isolation members 906 are rectangularly distributed on the bottom surface of the moving plate 604. Rack two 905 are respectively installed on the bottom surfaces of the four isolation members 906. A gear 903 is rotatably arranged on the inner wall of the installation slot two 902. The gear 903 meshes with the rack two 905. A rack one 904 is slidably installed on the inner side wall of the connecting frame 901. The rack one 904 meshes with the gear 903. A rubber pad 907 is installed between the bottom surfaces of the four racks one 904; In this embodiment, the bottom surface of the rubber pad 907 is made of flexible rubber, and the upper layer is made of hard rubber, so that once the rubber pad 907 contacts the slide rail 3 and under the influence of the speed of the moving block 2, the bottom layer of the rubber pad 907 is in close contact with the slide rail 3, slowing down the movement of the moving block 2.

[0022] In a further embodiment, referring to Figures 1-9 , limiting components 8 are symmetrically installed on the inner cavity bottom surface of the installation cavity 10. The limiting components 8 include sliding frames 801. The sliding frames 801 are symmetrically installed on the inner cavity bottom surface of the installation cavity 10. A sliding block 802 is slidably arranged in the inner cavity of the sliding frame 801. The two sliding blocks 802 are respectively installed on both sides of the moving plate 604; The installation cavity 10 is in a "cross" shape, and the rubber pad 907 is located in the inner cavity of the installation cavity 10; In this embodiment, during the process of the moving block 2 starting from the closed state, by increasing the current in the stator 11 to increase the magnetic force without changing the current direction, the moving plate 604 is moved from top to bottom. At this time, the distance between the moving plate 604 and the mover magnet 4 will become larger, and the magnetic force on the moving plate 604 exerted by the mover magnet 4 will decrease. At the same time, under the influence of the self-gravity of the moving plate 604 and the magnetic force in the stator 11, the copper sheet one 606 on the moving plate 604 will not contact the copper sheet three 609 and the copper sheet two 607. After the adjustment is completed, the current intensity in the stator 11 is appropriately reduced and the current direction is normally changed to drive the movement of the moving block 2; When the stator 11 no longer generates magnetic force or the magnetic force becomes very weak and cannot support the movement of the moving block 2, at this time, the moving plate 604 that has lost the magnetic adsorption of the stator 11 will move upward under the action of the mover magnet 4.

[0023] The working principle of the present invention is as follows: When the device is in use, first, the stator 11 in the slide rail 3 is powered on, and it is checked whether the control device and the system are normal; Subsequently, the operation of the device is controlled by the control device. During the operation, when for some reasons, the stator 11 will no longer generate magnetic force or the magnetic force becomes very weak and cannot support the movement of the moving block 2; At this time, the moving plate 604 that has lost the magnetic adsorption of the stator 11 will move upward under the action of the mover magnet 4, so that the plastic blocks 603 on the top of the moving plate 604 are respectively in contact with the copper sheet two 607 and the copper sheet three 609, thereby introducing the current in the storage battery 608 into the coil 602, making the coil 602 energized, and cooperating with the iron core 601 to form an electromagnet; The magnetic pole of the formed electromagnet is opposite to the magnetic pole of the mover magnet 4. Thus, when two adjacent moving blocks 2 approach each other, the magnetic pole of the electromagnet formed by the energization of the iron core 601 is opposite to that of the mover magnet 4, thereby generating a thrust to prevent collision between the two; Moreover, when the moving plate 604 rises, it will drive the spacer 906 and the rack two 905 to move upward. Subsequently, the rack two 905 drives the rack one 904 to move downward through the gear 903, thereby moving the rubber pad 907 on the bottom surface of the rack one 904 downward, making the rubber pad 907 in close contact with the slide rail 3, thereby increasing the resistance received when the moving block 2 moves, further slowing down the movement of the moving block 2, and achieving the effect of preventing the moving block 2 that has lost the support force of the stator 11 from colliding with the slide rail 3.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
