Description

Technical Field

[0001] The utility model relates to the technical field of drag chains, and in particular to a bidirectional running drag chain assembly for an RGV intelligent transport robot. Background Art

[0002] Drag chains are suitable for reciprocating motion situations and are widely used in automation equipment such as CNC machine tools, robotic arms, lifting and transportation equipment, and automated warehouses. They can pull and protect built-in cables, oil pipes, air pipes, water pipes, etc.

[0003] Existing drag chains can only be used for reciprocating movement in a straight line. However, in some special usage scenarios, such as the RGV intelligent handling robot, the robot needs to move along the Y axis in addition to the X axis, so the drag chain used with the robot is not suitable. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the drag chain in the prior art is not applicable to the RGV intelligent transport robot, thereby providing a bidirectional drag chain assembly for the RGV intelligent transport robot.

[0005] To this end, the utility model provides a bidirectional drag chain assembly for the RGV intelligent transport robot, including a joint bracket, a joint plate and a limit rod, the joint bracket having a first support plate fixedly assembled with the chain link at the end of the drag chain, and a second support plate connected to the joint plate, and a first through hole formed on the second support plate; the joint plate has a first joint portion rotatably mounted on the second support plate around a rotating axis, and a second joint portion for fixing to the transport robot, and the joint plate has arc holes located on both sides of its rotation center; the limit rod passes through the first through hole and the arc hole in sequence, and the limit rod can move in the arc hole.

[0006] A gasket is provided between the joint plate and the second support plate to reduce friction between the two.

[0007] The size of the gasket is larger than that of the first joint portion.

[0008] The gasket is a PTFE gasket.

[0009] The rotating shaft and the limiting rod are both screw-nut assemblies.

[0010] The chain link includes two chain plates arranged opposite to each other, the joint bracket is U-shaped, and the first support plate of the U-shaped joint bracket is arranged corresponding to the chain plates.

[0011] A clamping shaft is provided in the middle of the chain plate, and a clamping hole adapted to the clamping shaft is provided in the middle of the first support plate.

[0012] A limiting structure is provided between the first support plate and the chain plate. The limiting structure includes a limiting block provided on the chain plate, and a limiting groove provided on the first support plate and adapted to the limiting block.

[0013] The technical solution of this utility model has the following advantages:

[0014] 1. The utility model provides a bidirectional drag chain assembly, comprising a joint bracket, a joint plate, and a limit rod. The joint bracket has a first support plate fixedly assembled with the chain link at the end of the drag chain, and a second support plate connected to the joint plate. A first through-hole is formed on the second support plate. The joint plate has a first joint portion rotatably mounted on the second support plate about a rotation axis, and a second joint portion for fixing to a handling robot. The joint plate has arc-shaped holes located on both sides of its rotation center. The limit rod passes through the first through-hole and the arc-shaped hole in sequence, and the limit rod is movable within the arc-shaped hole. When the joint plate moves along the X-axis and Y-axis with the handling robot, the joint bracket can rotate relative to the joint plate, allowing the drag chain to move along the Y-axis while swinging in the X-axis direction. The arc-shaped hole cooperates with the limit rod to limit the swing angle, making it suitable for use with the handling robot.

[0015] 2. In the bidirectional drag chain assembly provided by the present invention, a gasket is provided between the joint plate and the second support plate to reduce the friction between the two, thereby extending the service life of the joint bracket and the joint plate.

[0027] Example

[0028] This embodiment provides a bidirectional drag chain assembly for an RGV intelligent transport robot. Figure 1 and Figure 2 As shown, it includes a joint bracket 1, a joint plate 7, a limiting rod 12 and a gasket 13.

[0029] The drag chain 2 is formed by assembling a plurality of chain links 3, such as Figure 2 and Figure 3 As shown, each chain link 3 includes two chain plates 14 arranged opposite to each other, and a clamping shaft 15 is provided in the middle of each chain plate 14 .

[0030] Connector bracket 1, such as Figure 2 and Figure 3 As shown, the drag chain 2 includes a first support plate 4 fixedly assembled with the chain link 3 at the end thereof, and a second support plate 5 connected to the joint plate 7. The second support plate 5 is formed with a first through-hole 6. The joint bracket 1 is U-shaped, with the first support plate 4 of the U-shaped joint bracket 1 correspondingly arranged with the chain plate 14. A locking hole 16 is provided in the middle of the first support plate 4, which is adapted to the locking shaft 15. A limiting structure is provided between the first support plate 4 and the chain plate 14. The limiting structure includes a limiting block 17 provided on the chain plate 14, and a limiting slot 18 provided on the first support plate 4, which is adapted to the limiting block 17.

[0031] Connector plate 7, such as Figure 2 and Figure 3 As shown, it has a first joint portion 9 rotatably mounted on the second support plate 5 around a rotation axis 8, and a second joint portion 10 for fixing to the handling robot. The joint plate 7 has arc holes 11 located on both sides of its rotation center.

[0032] Limit rod 12, such as Figure 2 and Figure 3 As shown, it passes through the first through hole 6 and the arc-shaped hole 11 in sequence, and the limiting rod 12 can move in the arc-shaped hole 11. The rotating shaft 8 and the limiting rod 12 are both screw and nut assemblies. It should be noted that in this embodiment, the tightening force of the nut is relatively small to allow the joint plate 7 and the joint bracket 1 to swing.

[0033] The gasket 13 is provided between the joint plate 7 and the second support plate 5 to reduce the friction between the two. The size of the gasket 13 is larger than the size of the first joint portion 9. In this embodiment, the gasket 13 is a polytetrafluoroethylene gasket.

[0034] The utility model provides a bidirectional drag chain assembly. When the joint plate 7 follows the handling robot to move in the X-axis and Y-axis directions, the joint bracket 1 can rotate relative to the joint plate 7, so that the drag chain 2 can move in the Y-axis direction and can swing in the X-axis direction (such as Figure 4As shown), the arc hole 11 cooperates with the limiting rod 12 to limit the swing angle, so that it is suitable for use with a handling robot.

[0035] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
