Description

Technical Field

[0001] This invention relates to the field of industrial robot technology, specifically to a robot device that translates along a track. Background Technology

[0002] Translational track robots have been widely used, primarily in workshop manufacturing settings. Patent publication CN109382847A discloses a support track for a robot platform capable of translational movement, as well as a displacement system and robot system incorporating this support track. It also discloses a support base for carrying the robot body and a fixed base. The support base is equipped with a power unit and slides horizontally on the base under the drive of the power unit. The base acts as a track to guide the robot's overall translational trajectory.

[0003] Currently, in existing technologies, the robot is driven by a power unit on the support base, and the support base slides horizontally with the base. It is necessary to consider improving the load-bearing capacity of the robot track to ensure the stability of the robot's movement trajectory. Summary of the Invention

[0004] The purpose of this invention is to provide a bottom-mounted movement device for a robot to solve the problems existing in the prior art.

[0005] The objective of this invention is achieved as follows: a bottom moving device for a robot, comprising a support base for supporting the robot body and a fixed base, wherein a power unit is installed on the support base and slides horizontally on the base under the drive of the power unit;

[0006] Guide rail plates are fixed on both the left and right sides of the base. The guide rail plates extend horizontally along the sliding direction of the support base, and the outer edge of the guide rail plates protrudes outward relative to the side of the base.

[0007] The support base is provided with two sets of rollers distributed front and back on both the left and right sides, and the roller sets are in rolling cooperation with the outer side of the guide rail plate.

[0008] Furthermore, the mounting roller assembly of the support base is provided as a downward protrusion.

[0009] Furthermore, the roller assembly includes an upper contact wheel, which is rotatably connected to the lower protrusion and rolls in contact with the upper surface of the guide rail plate.

[0010] Furthermore, the roller assembly also includes a lower contact wheel, which is rotatably connected to the lower protrusion and rolls in contact with the lower surface of the guide rail plate.

[0011] Furthermore, the roller assembly also includes a side contact wheel, and a side protrusion is provided on one side of the lower protrusion. The side contact wheel is rotatably connected to the side protrusion. The outer side of the guide rail plate is set as a vertical surface, and the side contact wheel rolls in contact with the outer side of the guide rail plate.

[0012] Furthermore, an oil scraper is fixedly connected to the side protrusion. As the support base moves, the oil scraper slides in contact with the upper surface of the guide rail plate to scrape off the oil stains on the guide rail plate.

[0013] Furthermore, the base is provided with guide plate positioning grooves extending along the movement direction of the support base on both the left and right sides. The cross-section of the guide plate is rectangular, and the long side of the rectangular cross-section of the guide plate is horizontal. The cross-section of the guide plate positioning groove is right-angled L-shaped, and the inner side of the guide plate matches the guide plate positioning groove.

[0014] Each guide rail plate is equipped with several locking bolts spaced apart along its length. The locking bolts pass through the guide rail plate from top to bottom and are threadedly connected to the base to fix the guide rail plate to the base.

[0015] Furthermore, each guide rail plate is equipped with a dust cover, which is fixedly connected to the base and extends along the length of the guide rail plate. The dust cover is used to cover the upper surface of the guide rail plate.

[0016] Furthermore, the dust cover is provided with a bolt receiving groove that extends along the length of the dust cover to accommodate all the locking bolts of the guide rail plate.

[0017] Furthermore, the dust cover is provided with an upper wheel body receiving groove, which extends along the length of the dust cover to accommodate the upper contact wheel moving within the upper wheel body receiving groove.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. Fix two guide rail plates to the left and right sides of the base to enhance the vertical load-bearing capacity of the robot's track and ensure the stability of the robot's movement trajectory so as to withstand the load perpendicular to the track generated by the robot during its movement.

[0020] 2. The load-bearing capacity of the guide rail plate itself can be improved, and the roller assembly has also been optimized accordingly to match the load state of the guide rail plate. The cross-sectional structure of the guide rail plate is rectangular. The side contact wheel directly bears the load in the horizontal direction perpendicular to the guide rail. At the same time, the upper contact wheel and the lower release wheel clamp the guide rail plate from the top and bottom respectively and roll along the length of the guide rail plate to better guide the robot body and its support base to move horizontally in a straight line.

[0028] The following will refer to the appendices in the embodiments of the present invention. Figure 1-7 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, a bottom-moving device for a robot is proposed, including a support base 2 for supporting the robot body 1 and a fixed base 5. The support base 2 is equipped with a power unit and slides horizontally on the base 5 under the drive of the power unit. Figure 4 As shown, the power unit of the support base 2 includes a drive motor 7 and a gear 8. A rack 9 is fixedly installed in the base 5. The drive motor 7 is fixedly installed on the support base 2. The gear 8 is fitted onto the output shaft of the drive motor 7.

[0030] like Figure 2-3 As shown, guide rail plates 3 are fixed on both the left and right sides of the base 5. The guide rail plates 3 extend horizontally along the sliding direction of the support base 2, and the outer side of the guide rail plates 3 protrudes outward relative to the side of the base 5.

[0031] The aforementioned support base 2 is provided with two sets of rollers distributed front and back on both the left and right sides, and the roller sets are in rolling cooperation with the outer side of the guide rail plate 3.

[0032] like Figure 6As shown, the mounting roller assembly of the support base 2 is configured as a lower protrusion 201.

[0033] like Figure 3-5 As shown, the roller assembly includes:

[0034] The upper contact wheel 203 is rotatably connected to the lower protrusion 201 and rolls in contact with the upper surface of the guide rail plate 3;

[0035] The lower contact wheel 204 is rotatably connected to the lower protrusion 201 and rolls in contact with the lower surface of the guide rail plate 3.

[0036] The side contact wheel 205 has a side protrusion 202 on one side of the lower protrusion 201. The side contact wheel 205 is rotatably connected to the side protrusion 202. The outer side of the guide rail plate 3 is set as a vertical surface. The side contact wheel 205 rolls and contacts the outer side of the guide rail plate 3.

[0037] As a further improvement, the aforementioned side protrusion 202 is fixedly connected to an oil scraper 206. As the support base 2 moves, the oil scraper 206 slides to contact the upper surface of the guide rail plate 3 to scrape off the oil on the guide rail plate 3. The oil scraper 206 needs to be misaligned with the locking bolt 4.

The guide plate 3 has a rectangular cross-section, and the long side of the rectangular cross-section of the guide plate 3 is set horizontally. The cross-section of the guide plate positioning groove 5a is a right-angled L-shape. The inner side of the guide plate 3 matches the guide plate positioning groove 5a, so that the guide plate positioning groove 5a is used as the positioning reference of the guide plate 3.

[0039] like Figure 2 , 3 As shown in Figures 7 and 8, each guide rail plate 3 is provided with a number of locking bolts 4 spaced apart along its length. The locking bolts 4 pass through the guide rail plate 3 from top to bottom and are threadedly connected to the base 5 to fix the guide rail plate 3 on the base 5.

[0040] like Figure 2 , 3 As shown, in order to fully protect the guide rail plate 3 and prevent dust from sticking to the surface of the guide rail plate 3 and affecting the movement of the support base 2, each guide rail plate 3 is equipped with a dust cover 6. The dust cover 6 is fixedly connected to the base 5 and extends along the length of the guide rail plate 3. The dust cover 6 is used to cover the upper surface of the guide rail plate 3.

[0041] like Figure 3 As shown, the dust cover 6 described above is equipped with:

[0042] Bolt receiving groove 6a extends along the length of dust cover 6 to accommodate all the locking bolts 4 of guide rail plate 3;

[0043] The upper wheel body receiving groove 6b extends along the length of the dust cover 6 to accommodate the upper contact wheel 203 moving within the upper wheel body receiving groove 6b.

[0044] The dust cover 6 has strip-shaped protrusions that separate the bolt receiving groove 6a and the upper wheel receiving groove 6b, which abut against the upper surface of the guide rail plate 3.
