Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing equipment, and specifically relates to a white body transfer and conveying device. Background Technology

[0002] In automobile production lines, due to process planning or workshop space limitations, it is often necessary to transfer body parts from one process platform to another. When the entire body needs to be transferred simultaneously in both vertical and horizontal directions, one solution is to use an integral lifting and horizontal movement frame, which is driven by a single horizontal and lifting motor. This frame cannot be adjusted according to the actual usage conditions, which limits its application to handling fixed-shape body parts. Utility Model Content

[0003] In view of the above problems, this application provides a body-in-white transfer and conveying device that can increase the scope of application of body-in-white.

[0004] This application provides a body-in-white transfer and conveying device, which includes a slide rail, a transfer frame, a first lifting frame, a first driving member, a second lifting frame, and a second driving member. The slide rail extends along a first direction; the transfer frame is movably disposed on the slide rail along the first direction, and the transfer frame has a first support and a second support spaced apart in a second direction, forming an accommodating space between the first support and the second support; the first lifting frame is used to carry the body-in-white, and is disposed on the first support and located within the accommodating space; the first driving member is used to drive the first lifting frame to move along the direction of gravity, and the first direction, the second direction, and the direction of gravity are perpendicular to each other; the second lifting frame is used to carry the body-in-white, and is disposed on the second support and located within the accommodating space; the second driving member is used to drive the second lifting frame to move along the direction of gravity, and the first driving member and the second driving member are electrically connected.

[0005] In the above technical solution, the space formed between the first bracket and the second bracket can accommodate large-sized, heavy-load vehicle bodies for transportation. At the same time, since the first and second lifting frames are driven by separate first and second driving components, they can be driven to move at the same height and speed, or they can be driven to be at different heights. This allows the first and second lifting frames to adapt to different body-in-white requirements, thus making the application scenarios more flexible.

[0006] In some embodiments, the first lifting frame includes a first guide rail, a first crossbeam, and a first column. The first guide rail is disposed on the first lifting frame and located within the accommodating space, and extends along the direction of gravity; the first crossbeam extends along the first direction and is used to support the body-in-white; one end of the first column is connected to the first crossbeam, and the other end is disposed on the first guide rail; the first driving member is disposed on the first crossbeam and is used to drive the first crossbeam and the first column to move along the direction of gravity.

[0007] In the above technical solution, the first lifting frame is formed by the first crossbeam and the first column. Compared with the first lifting frame structure formed by a whole plate structure, the weight of the lifting frame is reduced, which makes it easier for the lifting frame to move along the direction of gravity. At the same time, by setting the first guide rail, the movement of the first crossbeam and the first column is more stable when moving along the direction of gravity, thus improving the stability of the first lifting frame.

[0008] In some embodiments, the first bracket includes a first mounting beam extending along a first direction, the first mounting beam being located above the first crossbeam; the first driving member includes a first lead screw and a first motor. The axis of the first lead screw is parallel to the direction of gravity, the first mounting beam is provided with a threaded hole corresponding to the first lead screw, one end of the first lead screw is threaded into the threaded hole, and the other end of the first lead screw is rotatably disposed on the first crossbeam; the first motor is disposed on the first crossbeam and is used to drive the first lead screw to rotate.

[0009] In the above technical solution, the first motor drives the first lead screw to rotate, thereby driving the first lifting frame to move. The structure is simple and easy to implement.

[0010] In some embodiments, the first bracket further includes a first fall arrestor, the two ends of which are respectively connected to the first crossbeam and the first mounting beam.

[0011] In the above technical solution, by setting a first anti-fall device, the risk of damage to the body-in-white caused by the first lifting frame detaching from the first support is reduced, thereby improving the reliability of the body-in-white transfer and conveying equipment.

[0012] In some embodiments, the slide rail includes a first slide rail and a second slide rail spaced apart along the second direction, and the first bracket is movably disposed on the first slide rail along the first direction; the body-in-white transfer and conveying device further includes a first rack, a second motor, and a first gear. The first rack is disposed on one side of the first slide rail and extends along the first direction; the second motor is disposed on the first bracket; the first gear is disposed at the output end of the second motor and meshes with the first rack, and the second motor is used to drive the first gear to rotate, thereby causing the first bracket to move relative to the first slide rail along the first direction.

[0013] In the above technical solution, the first gear is driven to rotate by the second motor, so that the first gear moves relative to the first rack, thereby driving the first lifting frame to move, so that the first lifting frame has good self-locking performance and good positioning accuracy.

[0014] In some embodiments, the first slide rail includes a first horizontal plate and a first vertical plate. The first horizontal plate is used to support the first bracket; the first vertical plate is located below the first horizontal plate and connected to the first horizontal plate, with opposite sides of the first horizontal plate protruding from opposite sides of the first vertical plate along the second direction; the first vertical plate has a first side facing away from the accommodating space, and the first rack is disposed on the first side.

[0015] In the above technical solution, by setting the first rack on the side of the first vertical plate away from the accommodating space, the installation space on the first slide rail is fully utilized, thereby improving the compactness of the body-in-white transfer and conveying equipment.

[0016] In some embodiments, along the second direction, the first rack is located between the first gear and the first side, and the rotation axis of the first gear is parallel to the second direction.

[0017] In the above technical solution, the rotation axis of the first gear is parallel to the second direction, so that the second motor and the first gear are also located on the side away from the accommodating space, reducing the risk of the second motor interfering with the lifting of the first lifting frame.

[0018] In some embodiments, the transfer frame further includes a first rotating wheel and two limiting plates. The first rotating wheel is rotatably disposed on the first support, and the outer periphery of the first rotating wheel is used to abut against the first horizontal plate. The rotation axis of the first rotating wheel is parallel to the second direction. The two limiting plates are respectively disposed at opposite ends of the first rotating wheel in the second direction. The outer periphery of the two limiting plates protrudes from the outer periphery of the first rotating wheel to form a stepped surface. The two stepped surfaces abut against two opposite sides of the first horizontal plate in the second direction.

[0019] In the above technical solution, the two stepped surfaces respectively abut against the two sides of the first horizontal plate that are arranged opposite to each other in the second direction, thereby reducing the risk that the first rotating wheel will fall off the first horizontal plate due to the reaction force of the first rack on the first gear.

[0020] In some embodiments, the body-in-white transfer and conveying equipment further includes an adjustment module. The adjustment module is spaced apart from the slide rail along the first direction and is used to adjust the distance between the slide rail and the ground.

[0021] In some embodiments, the transfer frame further includes a connector, the two ends of which are disposed opposite to each other in the second direction and are respectively connected to the first support and the second support.

[0022] In the above technical solution, the overall integrity of the body-in-white transfer and conveying equipment is improved by using connectors. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In automobile production lines, due to process planning or workshop space limitations, it is often necessary to transfer body parts from one process platform to another. When the entire body needs to be transferred simultaneously in both vertical and horizontal directions, one solution is to use an integral lifting and horizontal movement frame, which is driven by a single horizontal and lifting motor. This frame cannot be adjusted according to the actual usage conditions, which limits its application to handling fixed-shape body parts.

[0034] To solve the above technical problems, refer to Figures 1-5This application provides a body-in-white transfer and conveying device, which includes a slide rail 10, a transfer frame 20, a first lifting frame 30, a first driving member 50, a second lifting frame 40, and a second driving member 60. The slide rail 10 extends along a first direction X; the transfer frame 20 is movably disposed on the slide rail 10 along the first direction X, and the transfer frame 20 has a first support 21 and a second support 22 spaced apart in a second direction Y, forming an accommodating space between the first support 21 and the second support 22; the first lifting frame 30 is used to carry the body-in-white, and is disposed on the first support 21 and located within the accommodating space; the first driving member 50 is used to drive the first lifting frame 30 to move along the gravity direction Z, and the first direction X, the second direction Y, and the gravity direction Z are perpendicular to each other; the second lifting frame 40 is used to carry the body-in-white, and is disposed on the second support 22 and located within the accommodating space; the second driving member 60 is used to drive the second lifting frame 40 to move along the gravity direction Z, and the first driving member 50 and the second driving member 60 are electrically connected.

[0035] In this technical solution, an accommodating space is formed between the first bracket 21 and the second bracket 22, which can accommodate large-sized, heavy-load vehicle bodies for transportation. At the same time, since the first lifting frame 30 and the second lifting frame 40 are driven by the independent first driving component 50 and the second driving component 60 respectively, the first lifting frame 30 and the second lifting frame 40 can be driven to move at the same height and speed, or the first lifting frame 30 and the second lifting frame 40 can be driven to be at different heights. This allows the first lifting frame 30 and the second lifting frame 40 to adapt to different body-in-white requirements, thus making the application scenarios more flexible.

[0036] According to some embodiments of this application, the first lifting frame 30 includes a first guide rail 31, a first crossbeam 32, and a first column 33. The first guide rail 31 is disposed on the first lifting frame 30 and located within the accommodating space, and extends along the gravity direction Z; the first crossbeam 32 extends along a first direction X, and is used to support the body-in-white; one end of the first column 33 is connected to the first crossbeam 32, and the other end is disposed on the first guide rail 31; a first driving member 50 is disposed on the first crossbeam 32 and is used to drive the first crossbeam 32 and the first column 33 to move along the gravity direction Z.

[0037] In some embodiments, the first bracket 21 includes two first mounting posts 211 spaced apart along a first direction X, the first mounting posts 211 extending along the gravity direction Z, and two first guide rails 31 respectively mounted on the two first mounting posts 211. The first bracket 21 also includes a first mounting beam 212, the two ends of which are connected to the middle portions of the two first mounting posts 211 in the first direction X. Two first uprights 33 are corresponding one-to-one with the two first guide rails 31, and the two first uprights 33 are located at opposite ends of the first crossbeam 32 in the first direction X.

[0038] For example, the first crossbeam 32 may be provided with locating pins and locating blocks for fixing the body-in-white.

[0039] In this technical solution, the first lifting frame 30 is formed by the first crossbeam 32 and the first column 33. Compared with the first lifting frame 30 structure which is a whole plate structure, the weight of the lifting frame is reduced, which makes it easier for the lifting frame to move along the direction of gravity Z. At the same time, by setting the first guide rail 31, the movement of the first crossbeam 32 and the first column 33 along the direction of gravity Z is more stable, thus improving the stability of the movement of the first lifting frame 30.

[0040] According to some embodiments of this application, the first bracket 21 includes a first mounting beam 212 extending along a first direction X, the first mounting beam 212 being located above the first crossbeam 32; the first driving member 50 includes a first lead screw 52 and a first motor 51. The axis of the first lead screw 52 is parallel to the direction of gravity Z, the first mounting beam 212 is provided with a threaded hole corresponding to the first lead screw 52, ​​one end of the first lead screw 52 is threaded into the threaded hole, and the other end of the first lead screw 52 is rotatably disposed on the first crossbeam 32; the first motor 51 is disposed on the first crossbeam 32 and is used to drive the first lead screw 52 to rotate.

[0041] In this technical solution, the first motor 51 drives the first lead screw 52 to rotate, thereby driving the first lifting frame 30 to move. The structure is simple and easy to implement.

[0042] According to some embodiments of this application, the first bracket 21 further includes a first anti-fall device 213, the two ends of which are connected to the first crossbeam 32 and the first mounting beam 212, respectively.

[0043] For example, the fall arrestor can be a fall arrestor having a connecting rope connecting the first crossbeam 32 and the first mounting beam 212, and a clamping mechanism for limiting the release of the connecting rope when the first mounting beam 212 is in a weightless state. This is prior art and will not be described further here.

[0044] In this technical solution, by setting the first anti-fall device 213, the risk of damage to the body-in-white caused by the first lifting frame 30 detaching from the first support 21 is reduced, thereby improving the reliability of the body-in-white transfer and conveying equipment.

[0045] According to some embodiments of this application, the slide rail 10 includes a first slide rail 1110 and a second slide rail 1210 spaced apart along a second direction Y. The first bracket 21 is movably disposed on the first slide rail 1110 along a first direction X. The body-in-white transfer and conveying device also includes a first rack 72, a second motor 70, and a first gear 71. The first rack 72 is disposed on one side of the first slide rail 1110 and extends along the first direction X. The second motor 70 is disposed on the first bracket 21. The first gear 71 is disposed at the output end of the second motor 70 and meshes with the first rack 72. The second motor 70 is used to drive the first gear 71 to rotate, thereby driving the first bracket 21 to move relative to the first slide rail 1110 along the first direction X.

[0046] In this technical solution, the first gear 71 is rotated by the second motor 70, so that the first gear 71 moves relative to the first rack 72, thereby driving the first lifting frame 30 to move, so that the first lifting frame 30 has good self-locking performance and good positioning accuracy.

[0047] According to some embodiments of this application, the first slide rail 1110 includes a first horizontal plate 111 and a first vertical plate 112. The first horizontal plate 111 is used to support the first bracket 21; the first vertical plate 112 is located below the first horizontal plate 111 and connected to the first horizontal plate 111, with opposite sides of the first horizontal plate 111 protruding from opposite sides of the first vertical plate 112 along the second direction Y; the first vertical plate 112 has a first side facing away from the accommodating space, and a first rack 72 is disposed on the first side.

[0048] In some embodiments, the first slide rail 1110 further includes a second horizontal plate 113, which is spaced apart from the first horizontal plate 111 along the gravity direction Z. A first vertical plate 112 is located between the second horizontal plate 113 and the first horizontal plate 111 and is used to connect the second horizontal plate 113 and the first horizontal plate 111. The second horizontal plate 113 is used to directly contact the ground, or the second horizontal plate 113 is used to indirectly contact the ground through other structural members.

[0049] In this technical solution, by setting the first rack 72 on the side of the first vertical plate 112 away from the accommodating space, the installation space on the first slide rail 1110 is fully utilized, thereby improving the compactness of the body-in-white transfer and conveying equipment.

[0050] According to some embodiments of this application, along the second direction Y, the first rack 72 is located between the first gear 71 and the first side, and the rotation axis of the first gear 71 is parallel to the second direction Y.

[0051] In this technical solution, the rotation axis of the first gear 71 is parallel to the second direction Y, so that the second motor 70 and the first gear 71 are also located on the side away from the accommodating space, reducing the risk of the second motor 70 interfering with the lifting of the first lifting frame 30.

[0052] According to some embodiments of this application, the transfer frame 20 further includes a first rotating wheel 24 and two limiting plates 25. The first rotating wheel 24 is rotatably disposed on the first support 21, and the outer periphery of the first rotating wheel 24 is used to abut against the first horizontal plate 111. The rotation axis of the first rotating wheel 24 is parallel to the second direction Y. The two limiting plates 25 are respectively disposed at opposite ends of the first rotating wheel 24 in the second direction Y. The outer periphery of the two limiting plates 25 protrudes from the outer periphery of the first rotating wheel 24 to form a stepped surface. The two stepped surfaces abut against the two opposite sides of the first horizontal plate 111 in the second direction Y.

[0053] In this technical solution, the two stepped surfaces respectively abut against the two sides of the first horizontal plate 111 that are opposite to each other in the second direction Y, thereby reducing the risk that the first rotating wheel 24 will fall off the first horizontal plate 111 due to the reaction force of the first rack 72 on the first gear 71.

[0054] According to some embodiments of this application, the body-in-white transfer and conveying equipment further includes an adjustment module 80. The adjustment module 80 is disposed at intervals along the slide rail 10 in a first direction X, and is used to adjust the distance between the slide rail 10 and the ground.

[0055] In some embodiments, taking the adjustment module 80 disposed on the first slide rail 1110 as an example, the adjustment module 80 includes a base 81, an adjustment plate 82, and a bolt 83. The base 81 is disposed on the ground, and the adjustment plate 82 is disposed on the base 81 and is movable along the direction of gravity Z. The adjustment plate 82 abuts against the second horizontal plate 113. The adjustment plate 82 is provided with a threaded hole that engages with the bolt 83. One end of the bolt 83 is inserted into the threaded hole and abuts against the base 81. The bolt 83 rotates relative to the threaded hole to adjust the distance between the adjustment plate 82 and the base 81 in the direction of gravity Z, thereby adjusting the distance between the first slide rail 1110 and the ground.

[0056] According to some embodiments of this application, the transfer frame 20 further includes a connector 23, the two ends of which are disposed opposite to each other in the second direction Y and are respectively connected to the first bracket 21 and the second bracket 22.

[0057] In this technical solution, the overall integrity of the body-in-white transfer and conveying equipment is improved by the connector 23.

[0058] Understandably, the second bracket 22, the second lifting frame 40, the second driving component 60, and the second slide rail 1210 are symmetrically arranged with the first bracket 21, the first lifting frame 30, the first driving component 50, and the first slide rail 1110. The technical effect they achieve is the same as that achieved by the second slide rail 1210 with the first bracket 21, the first lifting frame 30, the first driving component 50, and the first slide rail 1110, so it will not be described in detail here.

[0059] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0060] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application.
