Description

Lifting and positioning device, conveying system and production line Technical Field

[0001] The embodiments in this specification relate to the field of manufacturing technology, specifically to a lifting and positioning device, a conveying system, and a production line. Background Technology

[0002] In existing automobile manufacturing workshops, the movement of automotive parts between different production lines or different workstations on the same production line is typically achieved using automated conveyor systems. This improves the flexibility and efficiency of logistics within the workshop, thereby increasing automobile production efficiency and shortening the vehicle production cycle. Specifically, automated conveyor systems include conveying equipment (such as roller beds) and carriers (such as skids) mounted on the conveying equipment. Driven by the conveying equipment, the carriers carrying vehicle parts move automatically or semi-automatically on the conveying equipment.

[0003] When a carrier carrying vehicle parts moves to a processing station, it is necessary to restrict the carrier's degrees of freedom in all directions to achieve positioning, thereby improving the processing accuracy of the vehicle parts and enhancing the production quality of the production line. Specifically, to achieve vertical positioning of the carrier, it is necessary to restrict its degrees of freedom in directions other than vertical. In existing technologies, vertical positioning of the carrier is mainly achieved using the conveying components of the conveying equipment itself. Taking a roller bed conveyor skid as an example, when the skid moves to a designated station on the roller bed, the rollers of the roller bed provide a vertical force to the skid, lifting it to a certain height to achieve vertical positioning.

[0004] During the vertical positioning of the carrier using the conveyor component, in addition to the vertical force, the component itself may exert forces in other directions on the skid. This can cause the skid to wobble or move in other directions during its vertical movement. As the conveyor component wears and ages, the positioning accuracy of the carrier decreases. In cases of severe wear, the carrier may even become stuck, preventing it from smoothly moving to the next workstation, thus reducing production efficiency and product quality. Summary of the Invention

[0005] In view of this, several embodiments of this specification provide a lifting and positioning device, a conveying system, and a production line to improve the positioning accuracy of a vehicle.

[0006] One embodiment of this specification provides a lifting and positioning device, the lifting and positioning device comprising: a housing having a guide structure; wherein the guide structure has a guide direction; a lifting member cooperating with the guide structure; wherein the lifting member has a first end along the guide direction for contacting a lifted object, and a second end along the guide direction opposite to the first end; a driving member having a driving surface facing the lifting member, the second end of the lifting member abutting against the driving surface; when the driving member is driven to displace in a direction perpendicular to the guide direction, the driving surface can drive the lifting member to displace along the guide direction.

[0007] In some embodiments, the drive surface has a first target area and a second target area. When the contact position between the lifting member and the drive surface moves from the first target area to the second target area, the portion of the lifting member extending out of the housing along the guide direction gradually increases; when the contact position between the lifting member and the drive surface moves from the second target area to the first target area, the portion of the lifting member extending out of the housing along the guide direction gradually decreases.

[0008] In some embodiments, the housing further includes a support base; wherein the support base has a support surface for supporting the drive member; the support surface is perpendicular to the guide direction; and the average distance between the first target region and the support surface is less than the average distance between the second target region and the support surface.

[0009] In some embodiments, the region of the driving surface located between the first target region and the second target region forms a transition region, the average distance between the transition region and the support surface is greater than the average distance between the first target region and the support surface, and the average distance between the transition region and the support surface is less than the average distance between the second target region and the support surface.

[0010] In some embodiments, the driving surface is formed with a guide groove from the first target region to the second target region, and the contact position between the second end of the lifting member and the driving surface can vary along the guide groove.

[0011] In some embodiments, a roller is provided at the second end of the lifting member, and when the driving member is driven to move in a direction perpendicular to the guiding direction, the roller rolls relative to the driving surface.

[0012] In some embodiments, the lifting and positioning device further includes: a power unit; wherein the power unit is used to provide a force perpendicular to the guiding direction to the drive member; the power unit has a drive rod pivotally connected to the drive member.

[0013] One embodiment of this specification provides a conveying system, the conveying system including a roller bed and a skid disposed on the roller bed; the roller bed is equipped with a lifting and positioning device as described in the above embodiment; wherein the lifting and positioning device is used to lift and position the skid.

[0014] In some embodiments, the conveying system includes at least four of the lifting and positioning devices.

[0015] In some embodiments, the conveying system further includes: a height limiting structure installed on the roller bed corresponding to the lifting and positioning device; the height limiting structure is used to clamp the skid between the height limiting structure and the lifting device after the lifting device lifts the skid.

[0016] One embodiment of this specification provides a production line that includes a lifting and positioning device as described in the above embodiments or a conveying system as described in the above embodiments.

[0017] In several embodiments provided in this specification, a lifting and positioning device is provided on the conveying equipment of the conveying system, comprising a housing with a guide structure, a lifting member, and a driving member. The guide structure has a guide direction, and the driving member has a driving surface. When the driving member is driven to move in a direction perpendicular to the guide direction, or when the displacement of the driving member has a component in a direction perpendicular to the guide direction, the driving surface can drive the lifting member to move along the guide direction. Thus, the lifting and positioning device can be used to provide a lifting force along the guide direction for the carrier, reducing the swaying of the carrier during the guide direction positioning process and improving the positioning accuracy of the carrier along the guide direction.

[0037] Currently, in automobile manufacturing workshops, conveying systems typically include carriers for loading workpieces and conveying equipment for transporting the carriers. The conveying equipment includes conveying components. For example, in the case of a roller bed conveyor, the conveying component is the rollers of the roller bed. In the case of a belt conveyor, the conveying component is the conveyor belt. In existing technology, the positioning of the carriers is mainly achieved using the conveying components of the conveying equipment itself. Taking a roller bed conveyor skid as an example, a brief explanation of the existing methods for positioning carriers in a conveying system will be provided.

[0038] Please refer to Figure 1. Define the direction of the skid's movement along the roller bed as the X-direction, and the direction in which the skid is lifted as the Z-direction. Some rollers of the roller bed are connected to a linkage drive structure. When the skid moves to a designated position on the roller bed, all rollers on the roller bed will stop rotating. At this time, the linkage drive structure can drive the rollers connected to it to move along the Z-direction, thereby lifting the skid along the Z-direction and achieving the positioning of the skid in the Z-direction.

[0039] However, because the rollers lifting the skid may rotate during their Z-direction movement driven by the linkage, and because the contact surfaces between these rollers and the skid are curved, in addition to providing a Z-direction force to lift the skid, these rollers may also provide a force in the X-direction, causing the skid to move in the X-direction. As the above analysis shows, even when using some rollers to lift the skid for positioning, the skid still has considerable freedom in the X-direction. During the lifting process, the skid may wobble or displace in the X-direction, resulting in low positioning accuracy.

[0040] Furthermore, with the passage of time and frequent use of the roller bed, the rollers may wear and age. However, the degree of wear and aging may vary among different rollers, causing the contact point between the roller used to lift the skid and the skid to be misaligned. In this situation, even when the skid and the roller lifting it are stationary, the skid is unstable and may wobble or displace in the X-direction. During the lifting process, the skid's stability further decreases, increasing the probability of wobble or displacement in the X-direction. In cases of severe roller wear, the skid may even become stuck on part of the roller, preventing it from being smoothly conveyed to the next workstation.

[0041] To address the aforementioned issues and reduce the force applied to the carrier along the direction of movement of the conveying equipment, thereby minimizing potential swaying or displacement in directions other than the lifting direction during the lifting process and improving carrier positioning accuracy, researchers have proposed a lifting device. Please refer to Figure 2. In this lifting device, the lifting assembly is restricted by the lifting guide structure and can only move in a direction perpendicular to the conveying direction of the equipment. During the process of lifting the carrier using the lifting assembly, the assembly only applies a force perpendicular to the conveying direction, thus reducing potential swaying and improving the carrier's positioning accuracy to a certain extent.

[0042] However, as shown in Figure 2, in this lifting device, the drive structure that provides power to the lifting assembly consists of one driving wheel and two driven wheels. The driving wheel and driven wheels are connected by gear transmission or belt transmission. In production practice, researchers have found that, on the one hand, after a period of use, due to gear wear or belt loosening, the transmission efficiency of the drive structure will decrease or even fail to transmit power. At this point, production needs to be suspended to replace the gears or belts, leading to a decrease in the overall production efficiency of the production line. On the other hand, the lifting assembly is driven by two driven wheels, but the transmission between the driving wheel and the two driven wheels may be asynchronous. In this case, the carrier may still sway or displace in other directions during the lifting process. If the asynchronous transmission between the two driven wheels is severe, the carrier may become stuck on the lifting assembly and cannot be smoothly transferred to the next workstation.

[0043] Therefore, it is necessary to provide a lifting and positioning device, including a housing with a guide structure, a lifting member, and a driving member. The guide structure has a guide direction, and the driving member has a driving surface. When the driving member is driven to move in a direction perpendicular to the guide direction, the driving surface can drive the lifting member to move along the guide direction. Thus, the lifting and positioning device can provide a lifting force along the guide direction to the vehicle, reducing the swaying or displacement in other directions that may occur during the lifting process, and improving the positioning accuracy of the vehicle. At the same time, by utilizing the contact between the driving surface and the lifting member, the force in the direction perpendicular to the guide direction is converted into a force in the guide direction. The structure has high reliability, and the transmission efficiency can still be maintained at a high level after a long period of use. Therefore, the lifting and positioning device has a long service life and low maintenance cost.

[0044] Please refer to Figures 3 and 4. One embodiment of this specification provides a conveying system that may include a roller bed 200 and a skid 100 disposed on the roller bed 200.

[0045] The roller bed 200 can be used to convey the skid 100. Specifically, the roller bed 200 can have two tracks, each track having multiple sets of rollers mounted on it, which can rotate under the drive of the roller bed 200 motor. The roller bed 200 can be equipped with a lifting and positioning device 210 for lifting and positioning the skid 100.

[0046] The skid 100 can be used to load vehicle parts. Specifically, the skid 100 can be positioned on the track of the roller bed 200 and in contact with the rollers of the roller bed 200. As the rollers roll, the skid 100 can move along the track of the roller bed 200. When the skid 100 moves to a designated workstation, the lifting and positioning device 210 can contact the skid 100 and lift the skid 100 away from the rollers, thereby achieving positioning of the skid 100.

[0047] To improve the stability and positioning accuracy of the skid 100 during the lifting process, in this embodiment, the conveying system may include at least four lifting and positioning devices 210. Specifically, the lifting and positioning devices 210 may be arranged between the two tracks of the roller bed 200. For example, the four lifting and positioning devices 210 may be divided into two groups of two, with each group of lifting and positioning devices 210 positioned in the area adjacent to the tracks between them.

[0048] In some embodiments, the number of lifting and positioning devices 210 included in the conveying system may also be other values.

[0049] To further improve the positioning accuracy of the skid 100 along the lifting direction, in this embodiment, the conveying system may further include a height-limiting structure 220 corresponding to the lifting and positioning device 210 installed on the roller bed 200. Specifically, the height-limiting structure 220 can be used to clamp the skid 100 between the height-limiting structure 220 and the lifting and positioning device 210 after the lifting and positioning device 210 lifts the skid 100. To improve the stability of the skid 100 in the state of being clamped between the height-limiting structure 220 and the lifting and positioning device 210, the height-limiting structure 220 and the lifting and positioning device 210 can be respectively set on both sides of each track. Taking a conveying system including four height-limiting structures 220 as an example, the four height-limiting structures 220 can be divided into two groups of two, and each group of height-limiting structures 220 can be set in the area adjacent to the track on the side of one track away from the other track. The number of height-limiting structures 220 can be the same as the number of lifting and positioning devices 210, or it can be different from the number of lifting and positioning devices 210.

[0050] In some embodiments, the roller bed 200 may also be equipped with monitoring devices for monitoring the position and / or speed of the skid 100. For example, the monitoring devices may be position detection switches and / or deceleration detection switches.

[0051] In the conveying system provided in this specification, a lifting and positioning device is installed on the conveying equipment, comprising a housing with a guide structure, a lifting member, and a driving member. This lifting and positioning device utilizes the contact between the driving surface and the lifting member to convert forces acting in a direction perpendicular to the guide direction into forces acting in the guide direction. Thus, when the driving member is driven to displace in a direction perpendicular to the guide direction, the driving surface can drive the lifting member to displace along the guide direction, providing a lifting force along the guide direction to the carrier. This reduces carrier swaying during positioning and improves carrier positioning accuracy. Furthermore, due to the high reliability of the contact structure between the driving surface and the lifting member, the lifting and positioning device has a long service life and low maintenance costs, thereby improving the overall conveying efficiency of the conveying system and reducing its maintenance costs.

[0052] Please refer to Figures 5 to 8. This specification provides a lifting and positioning device 210, which may include: a housing 211 having a guide structure 2111, a lifting member 212 cooperating with the guide structure 2111, a driving member 213, and a power unit 214.

[0053] The housing 211 can be used to provide support for the lifting member 212, the driving member 213, and the power unit 214. Specifically, the housing 211 may include a guide structure 2111, which has a guiding direction and can be used to guide the lifting member 212 to move along the guiding direction. To reduce the swaying and displacement in other directions of the object being lifted during the lifting process, the guiding direction can be the vertical direction in which the object is lifted. In this embodiment, the guide structure 2111 may include a guide hole. In some embodiments, the guide structure 2111 can be a guide rail, guide plate, or other structure with a guiding function.

[0054] In some embodiments, the housing 211 may further include a support base 2112, which can be used to support the drive member 213 and the power unit 214. The contact surface between the support base 2112 and the drive member 213 is a support surface 21121 for supporting the drive member 213, and the support surface 21121 may be perpendicular to the guide direction.

[0055] The lifting member 212 can be used to lift an object, such as a lifting skid 100. Specifically, the lifting member 212 has a first end along the guide direction for contacting the object being lifted, and a second end along the guide direction opposite to the first end. In this embodiment, the lifting member 212 may include a limiting block 2121, a guide rod 2122, and a roller 2123.

[0056] In this embodiment, the limiting block 2121 can be used to directly contact the object being lifted. Specifically, the limiting block 2121 can be disposed at the first end of the lifting member 212 and extend out of the housing 211. To improve the stability of the object during the lifting process and increase the contact area between the lifting member 212 and the object being lifted, the projected area of ​​the limiting block 2121 in the guiding direction can be greater than the projected area of ​​the guide rod 2122 in the guiding direction.

[0057] In this embodiment, the guide rod 2122 can be used to cooperate with the guide structure 2111 to limit the movement direction of the lifting member 212 as the guiding direction. Specifically, when the guide structure 2111 includes a guide hole, the guide rod 2122 can be a round rod with a diameter smaller than the diameter of the guide hole. When the guide structure 2111 is a guide rail, the guide rod 2122 can be a slider that cooperates with the guide rail. The guide rod 2122 can be disposed between the limiting block 2121 and the roller 2123 to connect the limiting block 2121 and the roller 2123. To reduce wear caused by the contact between the limiting block 2121 and the housing 211, the guide rod 2122 can extend out of the housing 211.

[0058] In this embodiment, the roller 2123 can be used to abut against the drive member 213 to convert the force provided by the drive member 213 in the direction perpendicular to the guide direction into a force along the guide direction. Specifically, the roller 2123 can be disposed at the second end of the lifting member 212, and its contact surface with the drive member 213 can be a smooth arc surface. When the drive member 213 is driven to move in a direction perpendicular to the guide direction, the roller 2123 rolls relative to the drive surface 2131 included in the drive member 213. The roller 2123 can be a complete round wheel or a sector wheel. Since the roller 2123 can change the direction of the force provided by the drive member 213, the drive member 213 can be disposed in directions other than the guide direction, thereby reducing the size of the lifting and positioning device 210 in the guide direction, making it easier to install on the roller bed 200.

[0059] The driving member 213 can be used to provide driving force to the lifting member 212. Specifically, the driving member 213 can have a driving surface 2131 facing the lifting member 212 and abutting against the second end of the lifting member 212. When the driving member 213 is driven to displace in a direction perpendicular to the guiding direction, or when the displacement of the driving member 213 has a component in a direction perpendicular to the guiding direction, the driving surface 2131 can drive the lifting member 212 to displace along the guiding direction. The driving member 213 can move in any direction within a plane perpendicular to the guiding direction. The driving surface 2131 can be an inclined surface or a curved surface.

[0060] Please refer to Figures 8 and 9. In this embodiment, the driving surface 2131 may have a first target region 2133 and a second target region 2134. The average distance between the first target region 2133 and the supporting surface 21121 is less than the average distance between the second target region 2134 and the supporting surface 21121. As the contact position between the lifting member 212 and the driving surface 2131 moves from the first target region 2133 to the second target region 2134, the portion of the lifting member 212 extending out of the housing 211 along the guide direction gradually increases. Specifically, during the process of the roller 2123 moving from the contact position with the drive surface 2131 from the first target area 2133 to the second target area 2134, the lifting and positioning device 210 is in operation. The limiting block 2121 can move away from the housing 211 along the guide direction. After the limiting block 2121 contacts the object being lifted (such as the skid 100), it can lift the object away from the roller bed 200 along the guide direction until the object is in contact with the height limiting structure 220. When the contact position of the lifting member 212 with the drive surface 2131 moves from the second target area 2134 to the first target area 2133, the portion of the lifting member 212 extending out of the housing 211 along the guide direction gradually decreases. Specifically, during the process of the roller 2123 moving from the contact position with the drive surface 2131 from the second target area 2134 to the first target area 2133, the lifting and positioning device 210 is in a released state, and the limiting block 2121 can approach the housing 211 along the guide direction, so that the object being lifted (such as the skid 100) approaches the roller bed 200 along the guide direction until the object being lifted is separated from the limiting block 2121.

[0061] In this embodiment, the region of the driving surface 2131 located between the first target region 2133 and the second target region 2134 forms a transition region 2135. Specifically, the average distance between the transition region 2135 and the support surface 21121 can be greater than the average distance between the first target region 2133 and the support surface 21121, and the average distance between the transition region 2135 and the support surface 21121 can be less than the average distance between the second target region 2134 and the support surface 21121. To reduce wear on the contact surface between the roller 2123 and the driving surface 2131, the transition region 2135 can be smoothly connected to the first target region 2133 and the second target region 2134.

[0062] To limit the contact position between the roller 2123 and the driving surface 2131 and improve the positioning accuracy of the object being lifted, in this embodiment, the driving surface 2131 is formed with a guide groove 2132 extending from the first target area 2133 to the second target area 2134. The contact position between the second end of the lifting member 212 and the driving surface 2131 can vary along the guide groove 2132. Specifically, the width of the guide groove 2132 can be greater than the width of the roller 2123, so that the roller 2123 can be engaged within the guide groove 2132.

[0063] The power unit 214 can be used to provide power to the drive member 213 to drive the drive member 213 to move. Specifically, the power unit 214 may include a power supply structure 2141 and a drive rod 2142 pivotally connected to the drive member 213. In this embodiment, the power supply structure 2141 may be a single-guide rod cylinder. In some embodiments, the power supply structure 2141 may be a hydraulic cylinder, an electric push rod, an electric slide, an elastic element, or other structure capable of providing power to the drive member 213. The direction of the power provided by the power unit 214 to the drive member 213 may be perpendicular to the guide direction or in a direction other than perpendicular to the guide direction.

[0064] In the lifting and positioning device provided in the embodiments of this specification, the force acting in the direction perpendicular to the guide direction is converted into a force acting in the guide direction by the contact between the driving surface and the lifting member. Thus, when the driving member is driven to move in the direction perpendicular to the guide direction, the driving surface can drive the lifting member to move along the guide direction, thereby providing a lifting force along the guide direction for the vehicle. This reduces the swaying or displacement in other directions that may occur during the lifting process, improves the positioning accuracy of the vehicle, and the contact structure between the driving surface and the lifting member has high reliability, resulting in a long service life and low maintenance cost for the lifting and positioning device.
