Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a seventh axis of a robot. Background Art

[0002] The robot's seventh axis is also called the robot's external axis, walking axis or ground rail. It has the characteristics of a long guide rail, such as the 11.4m seventh axis. The guide rail system has a long coordination distance and is suitable for machine tool workpiece loading and unloading, welding, assembly, spraying, inspection, casting, forging, heat treatment, metal cutting, handling, palletizing, etc.

[0003] For example, the Chinese invention patent with application number 201811009122.1 discloses a seventh axis of an industrial robot, including a base, a pair of tracks mounted on the base, a slide table on the track for axial sliding, at least one side of the pair of tracks is provided with bar teeth, and the slide table is provided with gears meshing with the bar teeth and a driving system for driving the gears to rotate. The track and bar teeth of the seventh axis of the industrial robot are exposed to the outside. During operation, the robot arm takes out the workpiece immersed in the processing fluid and carries the workpiece dripping with the processing fluid to move along the axial direction of the track. After the exposed track and bar teeth are splashed with the processing fluid, on the one hand, the processing fluid is easily corroded by the track and bar teeth, resulting in poor or blocked movement of the slide table, and on the other hand, the dripping processing fluid cannot be reused, resulting in great waste.

[0004] Therefore, how to prevent the rails and bar teeth from being corroded and damaged by the machining fluid, and how to achieve the sequential utilization of the machining fluid, are technical problems that need to be solved urgently by those skilled in the art. Utility Model Content

[0005] The purpose of the utility model is to overcome the defects in the prior art and provide a robot seventh axis waterproof water receiving device which can effectively protect the rail and the bar teeth, prevent them from being corroded by the machining fluid, and realize the recycling of the machining fluid.

[0006] The cam is an angular channel that is fixed to the top of the base and covers the top of the slider rail assembly, and a gear that meshes with the bar gear and a driving system that drives the gear to rotate are installed on the slide. The bar gear is located between the pair of slider rail assemblies and is parallel to the slide rail of one side of the slider rail assembly. The outer end of the multi-section arm is fixed upward on the bottom of the slide, and the inner end bottom of the multi-section arm is fixed on the slider of the slider rail assembly. There is a gap between the top of the inner end of the multi-section arm and the bottom of the slide, and a top waterproof plate is provided in the gap. The top waterproof plate is fixed on the base through a supporting seat and covers the top of the bar gear and the slider rail assembly. A middle water inlet and a side water inlet are respectively provided on the top and both sides of the base. The middle water inlet is located between the pair of slider rail assemblies, and the side water inlet is located on the outer sides of the pair of slider rail assemblies.

[0007] Compared with the prior art, the utility model is advantageous in that: the utility model effectively protects the rails and the bar teeth to prevent them from being corroded by the processing fluid through the arrangement of the top waterproof plate, the middle water tank and the side water tank, and at the same time, the dripping processing fluid can be collected into the water tank to realize the recycling of the processing fluid, avoid the waste of the processing fluid, extend the service life of the robot, and effectively improve the working efficiency and reliability of the robot.

[0008] As an improvement, the multi-section arm includes a U-shaped arm section and a straight arm section, one end of the U-shaped arm section is fixedly connected to the slide, the other end of the U-shaped arm section is integrally formed with the straight arm section, the U-shaped arm section is located on the outside of the slider rail assembly and the U-shaped groove of the U-shaped arm section is opened upward, the bottom of the straight arm section is fixed on the slider of the slider rail assembly, the top waterproof plate is covered and arranged above the straight arm section, the outer side of the top waterproof plate is bent downward to form a waterproof folding edge, and the waterproof folding edge extends into the U-shaped groove. This technical solution forms a closed waterproof space between the slider rail assembly and the slide through the design of the multi-section arm. This design effectively prevents the processing fluid from entering the interior through the gap between the slider rail assembly and the slide, ensures the normal operation of the track and the bar gear, improves the waterproof performance of the robot's seventh axis, and extends the service life of the robot.

[0009] As an improvement, a side waterproof plate is provided between the U-shaped arm section and the slider rail assembly, and the side waterproof plate is fixedly arranged on the base and extends in the direction of the top waterproof plate. This technical solution further strengthens the sealing of the gap between the slider rail assembly and the slide table by providing a side waterproof plate between the U-shaped arm section and the slider rail assembly, effectively preventing the machining fluid from entering the interior from the side, providing more comprehensive protection for the track and bar teeth, improving the waterproof performance of the robot's seventh axis, enabling it to operate stably in a more severe environment, and extending the service life of the robot.

[0010] As an improvement, the middle water inlet trough is a square trough with an opening facing upward. Edge guards are fixed on the left and right sides of the middle water inlet trough. The edge guards are set vertically upward. A step for placing a tow line is provided between the edge guards and the edge of the middle water inlet trough. The top edge of the edge guard is bent outward to form an inclined water receiving edge. The inclined water receiving edge approaches the middle water inlet trough from top to bottom by the slide rail of the slider rail assembly, and is hidden under the top waterproof board. This technical solution cleverly combines the edge guard with the middle water inlet tank, and sets a step for placing the tow line between the edge guard and the edge of the water tank, which effectively prevents the tow line of the robot's seventh axis from being immersed in the processing fluid, avoids the accelerated corrosion and aging of the tow line due to long-term immersion, extends the service life of the tow line, reduces production costs, and improves production efficiency.

In addition, the design also adds a protective layer to prevent the processing fluid from splashing to other parts, improves the safety of the robot, and provides a more stable and reliable working environment for the robot.

This technical solution achieves a more secure fixing method by fixing the strip teeth on the top of the support block and fixing the eave extending in the direction of the middle water inlet on the support block. At the same time, the eave effectively guides a small amount of processing fluid dripping from the support block into the middle water inlet, avoiding the processing fluid from flowing to the ground from the gap between the support block and the oblique water receiving edge, thereby improving the recycling rate of the processing fluid, reducing production costs, improving production efficiency, and reducing environmental pollution.
