Description

Technical Field

[0002] A ground-track robot is a robot that moves on the ground, and it navigates and moves mainly through rails laid on the ground. It is usually used in scenarios that require precise positioning and frequent movement, such as automated production lines, logistics sorting systems, etc. The advantage of a ground-track robot is its stable operation and accurate positioning, but it also has limitations such as relatively low flexibility and the need to pre-lay rails. When the ground-track robot is in use, the maintenance of the rails is more important because the robotic arm slides back and forth on the rails.

[0003] In the prior art, when the ground rail robot is in use, the staff is required to regularly lubricate and maintain the ground rails. However, the equipment needs to be shut down during the lubrication and maintenance. The high frequency of shutdown causes the utilization rate of the equipment to decrease, thereby affecting the overall production efficiency. At the same time, the lubrication and maintenance are relatively troublesome, which increases the workload of the maintenance personnel. Therefore, a self-lubricating ground rail robot is designed.

The graphite column 508 is squeezed by the rotating plate 510, so that the graphite column 508 will not fall under normal circumstances.

[0024] In this embodiment, a protective mechanism 2 is provided at each automatic lubrication mechanism 5 on both sides of the top of the floor rail 1, and the protective mechanism 2 includes a rectangular frame 201 fixedly connected to the top of the floor rail 1, and slide grooves 202 are provided on both sides of the inner wall of the rectangular frame 201.

[0026] In this embodiment, a plurality of driving wheels 301 are disposed on both sides of the driving mechanism 3 , and the driving wheels 301 are adapted to the track grooves 101 .

[0027] In this embodiment, a mechanical arm 4 is disposed on the top of the driving mechanism 3 .

[0028] Working principle: A self-lubricating rail robot. When in use, a graphite column 508 is inserted into each socket 501. When the driving mechanism 3 moves, when the driving wheel 301 approaches each automatic lubrication mechanism 5, the driving wheel 301 will support the two T-blocks 504 at the top, so that the T-blocks 504 move up and compress the second spring 507. When the T-blocks 504 move up, the two ends of the two rotating plates 510 that are away from each other are driven to move upward through the two rectangular grooves 509, so that the push rod 512 is pushed up, and at the same time the third spring 514 is compressed, and at the same time the sides of the rotating plates 510 that are close to each other move away from each other, so that the graphite column 508 descends, and the graphite column 508 is lowered. The column 508 contacts the driving wheel 301. When the driving wheel 301 moves away, under the action of multiple springs, the graphite column 508 is clamped by the socket 501 again. In this way, each time the driving wheel 301 passes by, the graphite column 508 drops and contacts the driving wheel 301 under the action of gravity, and then is fixed, so that the bottom of the graphite column 508 can always contact the driving wheel 301, thereby achieving lubrication between the track groove 101 and the driving wheel 301. When the graphite column 508 is consumed, the user pulls the pull rod 209 to separate the L-shaped plug plate 205 from the middle slot 203, slides to the other side, and inserts a new graphite column 508 into the socket 501.
