Description

Technical Field

[0002] The magnetic drive conveyor line is an electromagnetically driven multi-motor intelligent conveying system, which is mainly composed of a fixed coil and a moving magnet. Each mover does not need to drag cables and can be independently controlled to adapt to the rhythm of different production stations, thereby improving the flexibility of the production line. The magnetic drive conveyor line usually includes a conveyor track that can produce a traveling wave magnetic field. The materials or products on the conveyor line usually need to carry a magnetic carrier. These magnetic carriers can be driven by the magnetic force on the track to achieve contactless suspension movement. The movers in traditional transmission devices cannot be adapted to the mixed scenarios of magnetic drive parts and belts at the same time. The power is transmitted between the mover and the belt through friction. The friction components on the belt are prone to wear. After severe wear, the contact pressure becomes smaller, affecting the transmission and the life of the transmission device. At the same time, the existing mover and belt height adjustment need to be separated, which is difficult to adjust and reduces the transmission efficiency of the transmission device.

[0028] 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 a fixed coil and a moving magnet. Each mover 40 does not need to drag cables, can be independently controlled, can adapt to the rhythm of different production stations, and improve the flexibility of the production line. The magnetic drive conveyor line uses magnetic force to realize the contactless and automatic transportation of materials or products on the conveyor line. It uses the magnetic principle to drive the transmission, without the need for traditional transmission parts such as chains and belts, thereby reducing friction and wear and improving the conveying efficiency and stability. The magnetic drive conveyor line usually includes a conveyor line track with magnetism, such as a permanent magnet track or an electromagnetic track. The materials or products on the conveyor line usually need to carry a magnetic carrier, such as a magnetic base or a magnetic vehicle. These magnetic carriers can be driven by the magnetic force on the track to achieve contactless suspension movement. At the same time, the magnetic drive conveyor line is usually equipped with a corresponding control system to achieve the guidance and speed adjustment of the materials or products. By adjusting the size and direction of the magnetic force, the position and movement trajectory of the carrier on the track can be controlled. In a traditional transmission device, power is transmitted between the mover and the belt through friction. The friction components on the belt are prone to wear. After severe wear, the contact pressure becomes smaller, affecting the transmission and reducing the life of the slide rail. At the same time, the friction component needs to adjust the friction force after the mover 40 enters the belt. Only appropriate friction force can enable the mover 40 to move smoothly on the belt. The friction force is related to the compression height and elastic coefficient of the spring. The compression height is divided into pre-compression and combined compression. Therefore, the adjustment of the spring needs to be separated from the overall height adjustment, which is more difficult to adjust, reducing the conveying efficiency of the transmission device 10.

[0029] refer to Figure 1 and Figure 2 To solve the above problems, the embodiment of the present application provides a transmission device 10, including: a magnetic drive component 20; a guide rail 30, the guide rail 30 extends from the magnetic drive component 20 along a first direction P1; a mover 40, the mover 40 includes a first connecting member 41, an adjusting member 42 and a second connecting member 43 movably connected to the guide rail 30, the second connecting member 43 is connected to the first connecting member 41 through the adjusting member 42; when the mover 40 is located at the first position K1 of the guide rail 30, the second connecting member 43 is adjacent to the magnetic drive component 20 to be driven by magnetic force; a belt conveyor 50, which is spaced apart from the magnetic drive component 20 in the first direction P1 and is located on one side of the guide rail 30; when the mover 40 moves to the second position K2 along the guide rail 30, the second connecting member 43 contacts the transmission belt 51 on the belt conveyor 50 away from the side of the guide rail 30 to be driven.

[0030] In the transmission device 10, the magnetic drive component 20 uses the magnetic force generated by the permanent magnetic material or the electromagnet to realize the contactless transmission of force or torque. When the mover 40 is in the first position K1, the mover 40 is adjacent to the magnetic drive component 20 to be driven by the magnetic force. In some embodiments, the transmission device 10 is provided with a guide rail 30, and the guide rail 30 extends from the magnetic drive component 20 along the first direction P1. In some embodiments, the guide rail 30 is set as one guide rail 30, and the mover 40 can pass through the magnetic drive component 20 and the belt conveyor 50 respectively on the guide rail 30, and the mover 40 can also contact the magnetic drive component 20 and the belt conveyor 50 at the same time on the guide rail 30. In some embodiments, the mover 40 includes a first connecting member 41, an adjusting member 42, and a second connecting member 43 that are movably connected to the guide rail 30. In some embodiments, the second direction P2 is perpendicular to the first direction P1, and the second connecting member 43 is connected to the first connecting member 41 through the adjusting member 42. The first connecting member 41, the adjusting member 42, and the second connecting member 43 are distributed in sequence in the second direction P2, and the adjusting member 42 can adjust the movement of the second connecting member 43 relative to the first connecting member 41 along the second direction P2. When the mover 40 is located at the first position K1 of the guide rail 30, the second connecting member 43 is adjacent to the magnetic drive member 20 to be driven by magnetic force. In some embodiments, the transmission device 10 includes a belt conveyor 50. The belt conveyor 50 has a transmission function. The belt conveyor 50 is spaced apart from the magnetic drive member 20 in the first direction P1 and is located on one side of the guide rail 30. In some embodiments, the mover 40 can move along the guide rail 30 in the first direction P1. The first position K1 is located on the side of the guide rail 30 located on the magnetic drive member 20. The second position K2 is located on the side of the guide rail 30 close to the belt conveyor 50. The mover 40 can move from the first position K1 to the second position K2 along the guide rail 30. When the mover 40 moves to the second position K2 along the guide rail 30, the second The connecting member 43 is in contact with the transmission belt 51 on the belt conveyor 50 on the side away from the guide rail 30 to be driven. The setting of the mover 40 in the first position K1 and the second position K2 can realize its application in two applicable scenarios: the magnetic drive component 20 and the belt conveyor 50. When the mover 40 moves to the first position K1, the drive of the mover 40 comes from the magnetic drive of the magnetic drive component 20. When the mover 40 moves to the second position K2, the drive of the mover 40 comes from the friction force generated by the contact between the second connecting member 43 and the transmission belt 51 in the belt conveyor 50. The driving device of the belt conveyor 50 drives the transmission belt 51 to move. Furthermore, the transmission belt drives the second connecting member 43 to move through the action of friction, thereby causing the position of the mover 40 to change.An adjusting member 42 is provided, which can adjust the distance between the second connecting member 43 and the first connecting member 41 and the guide rail 30, and can adapt to different transmission belts 51. The mover 40 can be adjusted according to the needs of different belt conveyor devices 50, which can reduce the damage of the transmission belt 51, help to improve the service life of the transmission device 10, and at the same time help to improve the conveying efficiency of the transmission device 10.

[0031] refer to Figure 1 , Figure 2 and Figure 3In some embodiments, the first connecting member 41 includes a movable body 410 and a mounting plate 412 connected to each other. The movable body 410 is slidably connected to the guide rail 30. The mounting plate 412 is connected to the adjusting member 42. The movable body 410 can move back and forth on the guide rail 30. The movable body 410 is supported by the guide rail 30. In some embodiments, the movable body 410 can be arranged between two magnetic rails. The movable body 410 can be made by compressing the coils together with epoxy material. The movable body 410 can adopt a magnetic movable body 40. The magnetic movable body 40 is made of a magnetic conductive material and has a magnetic circuit function and a conductive function. The mounting plate 412 is connected to the movable body 410. The movable body 410 and the mounting plate 412 can move in the first direction P1 along the guide rail 30 at the same time. In some embodiments, the second connecting member 43 includes a mounting seat 430 and a friction plate 431. The second connecting member 43 is connected to the first connecting member 41 through an adjusting member 42. The mounting plate 412, the adjusting member 42, the mounting seat 430, and the friction plate 431 can be arranged in sequence in the second direction P2. The adjusting member 42 is used to adjust the position height of the friction plate 431 relative to the first connecting member 41. In some embodiments, the friction plate 431 can contact the transmission belt 51 on the belt conveyor 50 at the second position K2. The friction plate 431 can absorb or transmit power through friction. In some embodiments, the friction plate 431 can be made of a polymer ternary composite material, specifically, a polymer compound is used as a binder, an inorganic or organic fiber is used as a reinforcing component, and a filler is used as a friction performance regulator or a compounding agent to achieve the effect of increasing the friction coefficient and wear resistance of the friction plate 431. The belt conveyor 50 includes a transmission belt 51 and a driving device. The driving device is used to drive the belt conveyor 50. In some embodiments, the driving device can be a motor. When the mover 40 is located at the second position K2, the friction plate 431 of the second connecting member 43 can contact the transmission belt 51. Since the friction plate 431 has a good friction coefficient, a large friction force will be generated on the contact surface between the transmission belt and the friction plate 431. The friction force can drive the mover 40 to move along the guide rail 30 in the first direction P1. At the same time, in some embodiments, in the above-mentioned movement stroke, there is a period of stroke in which the friction plate 431 and the transmission belt are in continuous contact, so that the friction force always exists, so that the mover 40 can be stably moved along the guide rail 30 in the first direction P1 under the action of the transmission belt. In this process, the mover 40 is driven to move along the guide rail 30 by the friction force between the transmission belt 51 and the friction plate 431, which has the effect of saving energy consumption compared to continuously using the magnetic force of the magnetic drive member 20 to move the mover 40.In some embodiments, a plurality of magnetic drive components 20 may be arranged along the first direction P1 of the guide rail 30, and a plurality of belt conveyors 50 may be arranged at intervals from the magnetic drive components 20 in the first direction P1. The belt conveyor 50 is located on one side of the guide rail 30, and can adapt to the rhythm of different production stations, thereby improving the flexibility of the production line of the transmission device 10. Specifically, the mover 40 may first pass through the magnetic drive component 20 along the guide rail 30 in the first direction P1, and the second connecting member 43 is adjacent to the magnetic drive component 20 to be driven by magnetic force. After that, the mover 40 moves to the area of ​​the second position K2, and the second connecting member 43 is away from the side of the guide rail 30 and contacts the transmission belt 51 on the belt conveyor 50 to be driven. After that, the mover 40 continues to move along the first direction P1 and moves to the next magnetic drive component 20 for magnetic drive. Therefore, the mover 40 is not limited to a certain driving mode, and the mover 40 can be applied to both the magnetic drive component 20 and the belt conveyor 50. In another embodiment, the mover 40 can contact the magnetic drive component 20 and the belt conveyor 50 at the same time. The mover 40 can be applied to two application scenarios: the magnetic drive component 20 and the belt conveyor 50 . It can adapt to the rhythm of different production stations, improve the flexibility of the production line of the transmission device 10 , and help improve the conveying efficiency of the transmission device 10 .

[0032] See also Figure 3 The adjusting member 42 includes an elastic member 420 . In one embodiment, the elastic member 420 includes a spring. The elastic member 420 is connected between the first connecting member 41 and the second connecting member 43 so that the second connecting member 43 can be close to or away from the first connecting member 41 . When the mover 40 is about to enter the second position K2 along the guide rail 30, the elastic force adjustment device can adjust the initial preload of the spring. The initial preload of the spring gives the friction plate 431 an initial elastic force to ensure that the friction plate 431 can enter the belt conveyor 50. At the same time, it can also ensure the friction force of the mover 40 relative to the conveying belt after entering the belt conveyor 50, so that the mover 40 can operate normally. The elastic member 420 can increase the practicality of the transmission device 10. At the same time, the elastic member 420 can provide a certain buffer for the friction plate 431 when the mover 40 enters the second position K2, which can reduce the wear of the friction plate 431 and the conveying belt, thereby increasing the service life of the mover 40 and the belt conveyor 50. The traditional method is prone to cause wear of the belt. After severe wear, the reduced contact pressure will affect the rotation of the belt, and then affect the transmission efficiency. Therefore, the provision of the elastic member 420 can improve the conveying efficiency of the transmission device 10.

[0033] refer to Figure 1 , Figure 2 and Figure 3In some embodiments, the adjusting member 42 further includes a guide member 421, which is used to guide the position of the friction plate 431 when it moves relative to the first connecting member 41 in the second direction P2. The guide member 421 is arranged along the second direction P2 to enable the second connecting member 43 to move along the second direction P2. The second direction P2 is perpendicular to the first direction P1. The guide member 421 and the elastic member 420 are arranged separately. In some embodiments, the guide member 421 is arranged along the second direction P2, and the elastic member 420 is arranged along the second direction P2. The guide member 421 and the elastic member 420 can be arranged in sequence. In some embodiments, multiple guide members 421 can be arranged, and in some embodiments, multiple elastic members 420 can be arranged to better ensure the cooperation between the mover 40 and the belt conveyor 50. In some embodiments, the elastic member 420 can also be sleeved on the guide member 421. In some embodiments, the elastic member 420 and the guide member 421 are arranged at intervals, and can be used in combination with the elastic member 420 sleeved on the guide member 421 to adapt to different application scenarios.

[0034] In some embodiments, the mover 40 further includes a slider 45, which is disposed at the lower end of the mover body 410, and the slider 45 is slidably connected to the guide rail 30. During the movement of the mover 40 along the guide rail 30 in the first direction P1, the slider 45 is always slidably connected to the guide rail 30, and the slider 45 can ensure that the mover 40 moves stably and safely on the guide rail 30, thereby improving the stability of the transmission device 10, and further improving the transmission efficiency of the transmission device 10. In some embodiments, the mounting seat 430 is provided with a mounting hole 4301, and the adjustment member 42 is inserted into the mounting seat 430 through the mounting hole 4301. Specifically, the elastic member 420 can be inserted into the mounting seat 430 through the mounting hole 4301, and the guide member 421 can be inserted into the mounting seat 430 through the mounting hole 4301. The mounting hole 4301 can make the adjustment of the adjustment member 42 more stable. In some embodiments, the adjusting member 42 further includes a height adjusting member 42, and the height adjusting member 42 includes an adjusting screw, which is sleeved on the second adjusting member 42. By rotating the adjusting screw, the friction plate 431 can be adjusted in height relative to the first connecting member 41. In some embodiments, the height adjusting member 42 can adopt a connecting rod mechanism, specifically, a parallelogram connecting rod mechanism or a V-shaped connecting rod mechanism. The second connecting member 43 includes a magnetic plate 432, which is placed along the second direction P2. When the mover 40 is located at the first position K1, the magnetic plate 432 is adjacent to the magnetic drive member 20 to be driven by magnetic force, so as to achieve the effect that the mover 40 is driven by the magnetic drive member 20. In some embodiments, the mover 40 also includes an anti-collision block 46, which is arranged at the end of the second connecting member 43 close to the magnetic drive component 20 along the first direction P1. When the mover 40 is about to contact the magnetic drive component 20 along the guide rail 30, the anti-collision block 46 can avoid the situation where the mover 40 is installed on the magnetic drive component 20 when the position of the mover 40 has not been debugged. The anti-collision block 46 can improve the safety of the transmission device 10, thereby improving the transmission efficiency of the transmission device 10.
