Description

Technical Field

[0001] The present application relates to the technical field of magnetic drive conveyor lines, and in particular to a magnetic drive conveyor line anti-retraction mechanism and a magnetic drive conveyor line. Background Art

[0002] The magnetic drive conveyor line is a multi-motor intelligent conveying system based on the principle of linear motors. The system is mainly composed of stator coils and movers. Each mover does not need to drag cables and can be independently controlled to adapt to the rhythm of different production stations and improve the flexibility of the production line.

[0003] During the movement, if the control system is disturbed, the position of the mover will be lost, and the mover will retreat. The main reasons for the mover position loss causing retreat are as follows:

[0004] 1. Magnetic field control: In magnetic drive conveyor lines, the magnetic field is the main source of power to drive the mover. When the mover loses its position, the effect of the magnetic field weakens or disappears, causing the mover to lose its power to move forward.

[0005] 2. Reverse force: In some cases, due to the reverse force of the magnetic field, the mover may be subjected to a backward force, which will cause the mover to move backward after losing its forward momentum due to the influence of the reverse force. Summary of the invention

[0006] Based on this, it is necessary to provide a magnetic drive conveyor line anti-retraction mechanism and a magnetic drive conveyor line that can effectively solve the phenomenon of the mover retreating.

[0007] A magnetic drive conveyor line back-stopping mechanism, comprising:

[0008] A stop base, the stop base being used to be arranged on the conveying module;

[0009] A stopper, the stopper being rotatably connected to the stopper base via a rotating shaft pin, the stopper having a blocking state and a releasing state, in which the stopper is fixed relative to the stopper base and can be used to abut against the mover, and in the releasing state, the stopper is rotatable relative to the stopper base to release the mover;

[0010] A reset member is connected between the stop member and the stop base, and is used to provide a reset force that causes the stop member to tend to remain in the blocking state.

[0011] In one of the embodiments, the magnetic drive conveyor line stop mechanism further includes a buffer member rotatably connected to the stop member, and the buffer member is used to abut against the mover to provide buffering for the mover.

[0012] In one embodiment, the buffer member at least partially extends out of the stop member;

[0013] And / or, the buffer member is rotatably connected to the stop member via a rotating shaft.

[0014] In one embodiment, a threaded hole is formed on the stop base, a rotating hole is formed on the stop member, the rotating shaft pin is passed through the rotating hole and is rotatably connected to the rotating hole, and the rotating shaft pin is threadedly connected to the threaded hole.

[0015] In one of the embodiments, a limiting groove is provided on the retaining base; the retaining member has a connecting portion, the connecting portion can be rotatably connected in the limiting groove through the rotating shaft pin, and the connecting portion can abut against the first side wall and the second side wall arranged opposite to the limiting groove.

[0016] In one embodiment, the reset member is connected between the first side wall and the stop member; a notch is provided on the second side wall, and the stop member also has a matching portion connected to one end of the connecting portion close to the notch, and the matching portion at least partially extends into the notch, and the buffer member is arranged on the matching portion, and the notch is used to avoid the matching portion so that the buffer member abuts against the mover.

[0017] In one embodiment, an abutment surface is provided at one end of the mating portion close to the connecting portion, and a limiting inclined surface is provided at one end of the second side wall close to the notch. The limiting inclined surface is inclined relative to the second side wall, and the limiting inclined surface can abut against the abutment surface of the stop member.

[0018] In one of the embodiments, the retaining member further has an abutting inclined surface, and the abutting inclined surface is arranged obliquely relative to the side wall of the retaining member. In the blocking state, the abutting inclined surface can abut against the mover.

[0020] In one of the embodiments, the magnetically driven conveyor line further comprises a conveying module and a plurality of movers capable of moving along an extension direction of the conveying module, and the magnetically driven conveyor line stop mechanism is disposed on the conveying module.

[0021] In the above scheme, the stop member is rotatably connected to the stop base through a rotating shaft pin, and the stop member can switch between a blocking state and a release state. When the mover moves along the set direction, the stop member is in a release state, and the stop member is rotatable relative to the stop base, so that the stop member can be switched from the blocking state to the release state to release the mover. When the mover moves backward, the stop member can abut against the mover, and the stop member can play a blocking role on the moving member moving backward, thereby effectively solving the problem of the moving member moving backward; by setting a reset member, the stop member can be driven to return from the release state to the blocking state.

[0037] Please refer to FIG. 1 and FIG. 2 , the embodiment of the present application relates to a magnetic drive conveyor line backstop mechanism 10, which is arranged on a magnetic drive conveyor line 20. Specifically, the magnetic drive conveyor line 20 includes a conveying module 600 and a plurality of movers 700 that can move along the extending direction of the conveying module 600, and the magnetic drive conveyor line backstop mechanism 10 is arranged on the conveying module 600. More specifically, the magnetic drive conveyor line backstop mechanism 10 may include a plurality of magnetic drive conveyor line backstop mechanisms 10, and the plurality of magnetic drive conveyor line backstop mechanisms 10 are arranged on the conveying module 600 at intervals.

[0038] Please refer to Figures 2 and 3. The magnetic drive conveyor line backstop mechanism 10 includes a backstop base 100, a backstop member 200, and a reset member 300 connected between the backstop base 100 and the backstop member 200. The backstop member 200 is rotatably connected to the backstop base 100, and the backstop member 200 can make the mover 700 move in one direction and prevent the mover 700 from retreating. The backstop base 100 is used to be arranged on the conveying module 600. The backstop base 100 may include a plurality of backstop bases 100, and the plurality of backstop bases 100 are arranged on the conveying module 600 at intervals.

[0039] The stop member 200 is rotatably connected to the stop base 100 via a rotating shaft pin 400. Specifically, a threaded hole is provided on the stop base 100, a rotating hole is provided on the stop member 200, the rotating shaft pin 400 is inserted into the rotating hole, rotatably connected to the rotating hole, and the rotating shaft pin 400 is threadedly connected to the threaded hole. More specifically, the upper half of the rotating shaft pin 400 is rotatably connected to the rotating hole. The lower half of the rotating shaft pin 400 is threadedly connected to the threaded hole. Exemplarily, the rotating shaft pin 400 is a screw pin.

[0040] Please refer to Figures 2, 4 and 5. The stopper 200 has a blocking state and a release state. In the blocking state, the stopper 200 is fixed relative to the stopper base 100, and the stopper 200 can be used to abut against the mover 700. In the release state, the stopper 200 can rotate relative to the stopper base 100 to release the mover 700. The reset member 300 is used to provide a reset force that tends to keep the stopper 200 in the blocking state. Exemplarily, the reset member 300 is a spring.

[0041] It should be understood that the stop member 200 can be switched between a blocking state and a release state. When the mover 700 moves along a set direction, the stop member 200 is in a release state, and the stop member 200 can rotate relative to the stop base 100, so that the stop member 200 can be switched from a blocking state to a release state to release the mover 700. When the mover 700 retreats, the stop member 200 can abut against the mover 700. At this time, the stop member 200 is in a blocking state, and the stop member 200 can play a blocking role on the retreating mover 700, thereby effectively solving the phenomenon of the mover 700 retreating. After the mover 700 moves away from the stop member 200, the reset member 300 provides a reset force for the stop member 200 to switch the stop member 200 from the release state to the blocking state.

[0042] Please refer to FIG. 3, FIG. 4 and FIG. 5. According to some embodiments of the present application, optionally, the magnetic drive conveyor line backstop mechanism 10 further includes a buffer 500 rotatably connected to the backstop 200, and the buffer 500 is used to abut against the mover 700 to provide buffering for the mover 700. Specifically, the buffer 500 is arranged corresponding to the mover 700. When the mover 700 abuts against the buffer 500, the mover 700 can drive the buffer 500 to rotate relative to the backstop 200 when moving.

[0043] By rotatably connecting the buffer member 500 to the stop member 200, the buffer member 500 can abut against the mover 700, thereby providing a buffer for the mover 700 and effectively preventing the mover 700 from damaging the stop member 200. At the same time, when the mover 700 moves, it can drive the buffer member 500 to rotate relative to the stop member 200, so that the buffer member 500 does not affect the movement of the mover 700.

[0044] The buffer 500 is rotatably connected to the stopper 200 via a rotating shaft. Specifically, a mounting hole is provided on the stopper 200, the rotating shaft is fixedly connected in the mounting hole, and the buffer 500 is sleeved on the rotating shaft and can rotate relative to the rotating shaft. In this embodiment, the buffer 500 adopts a rubber-coated bearing. In other embodiments, the buffer 500 can also adopt a rubber ring.

[0045] Please refer to FIG. 3, FIG. 4 and FIG. 5. According to some embodiments of the present application, optionally, the buffer 500 is at least partially extended from the stop member 200. Specifically, the stop member 200 is provided with a mounting groove, and the buffer 500 is installed in the mounting groove. By extending the buffer 500 at least partially from the stop member 200, the buffer 500 can abut against the mover 700, and when the mover 700 moves, relative friction will not be generated with the stop member 200, and the movement of the mover 700 will not be affected.

[0046] Please refer to Figures 3, 4 and 5. According to some embodiments of the present application, optionally, a limiting groove 110 is provided on the stop base 100. The stop member 200 has a connecting portion 210, which is rotatably connected to the limiting groove 110 through a rotating shaft pin 400, and the connecting portion 210 can abut against the first side wall 111 and the second side wall 112 arranged opposite to the limiting groove 110, which can limit the stop member 200 and prevent the stop member 200 from rotating excessively.

[0047] Specifically, there is a spacing between the stopper 200 and the limiting groove 110 to ensure that the connecting portion 210 can rotate relative to the stopper base 100. It should be noted that the size of the spacing is not limited in this application and can be set according to the rotation angle of the connecting portion 210 relative to the stopper base 100.

[0048] Please refer to Figures 3, 4 and 5. According to some embodiments of the present application, optionally, the reset member 300 is connected between the first side wall 111 and the stop member 200. A notch is provided on the second side wall 112, and the stop member 200 also has a matching portion 220 connected to one end of the connecting portion 210 close to the notch, and the matching portion 220 at least partially extends into the notch. The buffer member 500 is disposed on the matching portion 220, and the notch is used to avoid the matching portion 220 so that the buffer member 500 abuts against the mover 700. One end of the matching portion 220 away from the first side wall 111 and one end of the stop base 100 away from the first side wall 111 are disposed corresponding to the mover 700.

[0049] Referring to FIG. 3 , FIG. 4 and FIG. 5 , according to some embodiments of the present application, optionally, an end of the matching portion 220 close to the connecting portion 210 is provided with an abutting surface 221, and an end of the second side wall 112 close to the notch is provided with a limiting inclined surface 1121, and the limiting inclined surface 1121 is inclined relative to the second side wall 112. The limiting inclined surface 1121 can abut against the abutting surface 221 of the stop member 200.

[0050] When the backstop 200 is in the release state, there is a distance between the limiting inclined surface 1121 and the abutting surface 221 of the backstop 200, and there is also a distance between the first side wall 111 and the backstop 200. The limiting inclined surface 1121 and the first side wall 111 will not play a limiting role, so that the backstop 200 can be rotated relative to the backstop base 100. When the backstop 200 is in the blocking state, the limiting inclined surface 1121 abuts against the abutting surface 221 of the backstop 200 to limit the position of the backstop 200, so that the backstop 200 can be fixed relative to the backstop base 100. It should be noted that the maximum rotation position of the backstop 200 is the position where the first side wall 111 abuts against the backstop 200.

[0051] Referring to Fig. 3, Fig. 4 and Fig. 5, according to some embodiments of the present application, optionally, the stopper 200 further has an abutting inclined surface 230, and the abutting inclined surface 230 is inclined relative to the side wall of the stopper 200. In the blocking state, the abutting inclined surface 230 can abut against the mover 700, and the abutting inclined surface 230 can play a blocking role on the mover 700.

[0052] Please refer to Figures 1, 2 and 3. The present application also provides a magnetic drive conveyor line 20, including a conveying module 600, a plurality of movers 700 that can move along the extension direction of the conveying module 600, and a magnetic drive conveyor line stop mechanism 10.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
