Description

Technical Field

[0001] This utility model belongs to the field of robotics technology, and in particular relates to a fully enclosed ground track for robot spraying. Background Technology

[0002] In robotic painting operations, a seventh axis is often needed to assist in completing the painting action. Due to the harsh conditions of the painting site, paint mist and dust inevitably fall on cables, motors, and other surfaces, accumulating over time and affecting the robot's normal operation. A fully enclosed robot track effectively solves this problem. As the core actuator of the automated painting system, it extends the working radius of the industrial robot through high-precision linear motion, solving the coverage problem caused by excessively large workpieces or limited space in traditional painting methods.

[0003] Comparing with Chinese Patent CN216913819U, a fully enclosed robot track device is disclosed, relating to the field of robotics. It includes a robot track body, and further includes: a closed shell, disposed on the robot track body to enclose and seal it, the closed shell having an opening along the robot's direction of travel; a base for mounting the robot, the base having a support extending into the closed shell from the opening and connected to the robot track body, the robot track body driving the base and robot to move by moving the support; and an opening closing mechanism, including: a closing strip for sealing the opening; and a closing position adjustment mechanism disposed on the support, the closing position adjustment mechanism adjusting the sealing position of the closing strip on the opening so that the closing strip can move with the support body within the opening to seal the area outside the location of the support body within the opening.

[0004] However, the paint mist and dust from the aforementioned patents tend to accumulate in the recesses of the enclosed zone, which increases the difficulty of cleaning and makes it difficult for the guide wheels to move, reducing the accuracy of movement. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a fully enclosed ground track for robot painting, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fully enclosed ground rail for robot spraying includes a frame device for support and fixation, and a dynamic shielding device for enclosed reciprocating movement disposed in the middle of the frame device. The dynamic shielding device is equipped with a translation device for supporting the reciprocating movement of the robot. The frame device includes a frame base with four baffles evenly distributed at its four corners. Two limiting slide rails are symmetrically installed inside the frame base, and several limiting sliders are evenly installed on the limiting slide rails. A rack is installed on the frame base near one of the limiting slide rails, and a cable inlet is provided at one end of the frame base. The dynamic shielding device includes a shielding belt with a fixed end assembly and an adjusting end assembly at each end. Two rollers are rotatably installed in the fixed end assembly and the adjusting end assembly, distributed vertically, to support the movement of the shielding belt. The translation device includes a slide plate fixedly connected to the limiting sliders and the shielding belt. A servo motor is installed at one end of the slide plate, and a gear is installed at the output end of the servo motor. The gear meshes with the rack for transmission. The end of the slide plate away from the servo motor is used to mount the robot and is provided with a robot cable hole.

[0008] Furthermore: Several foot pads are evenly distributed at the bottom of the rack base, and a cable drag chain box is installed inside the rack base.

[0009] Furthermore: a limit stop is installed at each end of the limit slide rail, and the stop is a labyrinth type.

[0010] Furthermore: the fixed end assembly includes two symmetrically arranged fixed plates, and a sealing plate is installed on the fixed plates; the adjusting end assembly includes two symmetrically arranged tensioning plates, and a sealing plate is also installed on the tensioning plates. Several adjusting waist holes are evenly distributed in the middle of the tensioning plates, and adjusting bolts are installed in the adjusting waist holes.

[0011] Furthermore, the shielding belt is equipped with clearance holes to allow passage for cables and servo motor outputs.

[0012] Furthermore: a motor cover is provided on the outside of the servo motor, and the motor cover and the slide plate are connected by bolts.

[0013] Furthermore, a motor cable hole is provided near the servo motor on the skateboard.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] The combination of a flat shielding belt, labyrinthine baffles, and sealing plates at both the fixed and adjustable ends creates multiple physical barriers, forming a dynamic, fully enclosed structure. This facilitates surface dust cleaning while effectively preventing paint mist, dust, and other contaminants from intruding into the track, protecting precision transmission components (such as racks, gears, and limit rails) from corrosion and buildup. This significantly reduces the failure rate and extends the equipment's lifespan. The dynamic sealing mechanism, driven by a sliding plate that moves the shielding belt synchronously with roller support, achieves continuous and dynamic sealing of the track's internal structure, ensuring that the track's internal cavity remains effectively covered regardless of the robot's position. The sliding plate of the translation device is directly connected to the limit sliders and shielding belt, integrating the robot's load-bearing, movement guidance, and dynamic sealing functions into a compact and rigid structure. Symmetrically arranged double limit rails and evenly distributed limit sliders provide stable and precise linear guidance for the sliding plate, effectively preventing jamming and crawling during operation. The system ensures the repeatability and accuracy of the robot's spraying trajectory. The servo motor-driven gear and fixed rack transmission scheme offers high efficiency and fast response, meeting the speed and stability requirements of complex robot spraying paths. The dynamic masking device features a tensioning plate with adjustable holes and bolts at one end, allowing for easy adjustment of the masking belt tension. This simplifies initial installation and facilitates subsequent maintenance due to belt elongation, restoring optimal tension without requiring parts replacement. A clear and standardized cable path is established through cable entry points, cable chain boxes, motor cable holes, and robot cable holes. This rational cable layout avoids exposed cables and keeps the equipment interior clean, facilitating inspection and troubleshooting. This robust protection of core transmission components adapts to highly polluted spraying environments, reduces downtime due to equipment failure, and ensures the robot's long-term operational stability and accuracy, thereby improving the consistency of sprayed product quality.

At the same time, the slide plate 301 moves along the limit slide rail 104 under the restriction of the limit slider 105 to ensure the direction of movement. The edge of the shielding belt 206 cooperates with the baffle 107 and the sealing plate 205 to prevent paint mist and dust from entering.

[0028] In this embodiment: the dynamic shielding device 2 includes a shielding belt 206, with a fixed end assembly and an adjusting end assembly respectively provided at both ends of the shielding belt 206.

Since the fixing plate 201 is fixedly connected to the frame base 101, one end of the masking belt 206 is fixed by the roller 208. Therefore, the other end of the masking belt 206 is pulled by the roller 208 on the tension plate 202 to form tension. Finally, tighten the adjusting bolt 204 that moves along the adjusting waist hole 203 to fix it; When the robot is spraying, the slide plate 301 drives the masking belt 206 to move under the support of the roller 208, covering the inside of the frame base 101 and preventing paint mist and dust from entering;

[0029] In this embodiment: the translation device 3 includes a slide plate 301 fixedly connected to the limiting slider 105 and the shielding belt 206.

Then the motor cover 303 and the robot are fixedly installed on the slide plate 301. When the robot is spraying, the servo motor 302 drives the gear 306 to mesh with the rack 106, which drives the slide plate 301 to support the movement of the robot.

[0030] Working principle: During installation, first fix the frame base 101 to the ground with the foot bracket 102, then pass the composite cable through the cable inlet 108 into the frame base 101, fix it along the cable drag chain box 103, and pass it through the motor cable hole 305 on the slide plate 301 to connect with the servo motor 302, and through the robot cable hole 304 to connect with the robot. Then fix the motor cover 303 and the robot on the slide plate 301. Then pull the tension plate 202. Since the fixing plate 201 is fixedly connected to the frame base 101, one end of the shielding belt 206 is fixed by the roller 208. Therefore, the other end of the shielding belt 206 is pulled by the roller 208 on the tension plate 202 to form tension. Finally, tighten the adjusting bolt 204 that moves along the adjusting waist hole 203 to fix it.

[0031] During robot painting, servo motor 302 drives gear 306 to mesh with rack 106, which in turn drives slide plate 301 to support the robot's movement. At the same time, slide plate 301 moves along limit slide rail 104 under the restriction of limit slider 105 to ensure the direction of movement. In addition, slide plate 301 drives masking belt 206 to move under the support of roller 208, which masks the inside of frame base 101. At the same time, the edge of masking belt 206 cooperates with baffle 107 and sealing plate 205 to prevent paint mist and dust from entering. Cable drag chain box 103 moves with composite cable to form protection.
