Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for spraying robots, specifically a lifting device for spraying robots. Background Technology

[0002] A painting robot, also known as a spray painting robot, is an industrial robot that can automatically spray paint or apply other coatings. A painting robot mainly consists of a robot body, a computer, and a corresponding control system.

[0003] In the prior art, a painting robot lifting device with authorization announcement number CN222518963U includes a receiving platform, a lifting arm at the bottom of the receiving platform, and a robot moving component installed at the top of the receiving platform. The lifting arm can raise or lower the painting robot installed on the receiving platform, and the robot moving component can allow the painting robot to move horizontally. Thus, the overall lifting and horizontal movement of the painting machine is realized, which greatly increases its painting range and improves its painting efficiency.

[0004] When this device is in operation, its lifting arm can only raise the painting machine to a fixed height, making it difficult to adjust the robot's height according to work needs. When the robot is moved horizontally to one side of the receiving platform by the moving component, the center of gravity of the receiving platform changes, which can easily cause the lifting platform to shake during the operation of the painting robot, affecting the quality and safety of the painting work. Utility Model Content

[0005] The purpose of this invention is to provide a lifting device for a painting robot to solve the problem of easy shaking of the lifting device when the painting robot is working, as mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for a painting robot, comprising a base, a receiving platform at the top of the base, two tracks fixedly connected to the top of the receiving platform, a movable plate slidably connected to the top of the two tracks, a receiving plate fixedly connected to the top of the movable plate, a fixed block at the bottom of the receiving platform, a counterweight fixedly connected to the bottom of the fixed block, a placement groove adapted to the counterweight at the top of the base, and two lifting components disposed between the base and the receiving platform.

[0007] Preferably, each of the two tracks is rotatably connected to a first threaded rod, the two first threaded rods respectively pass through both ends of the moving plate and are threadedly connected to the moving plate, and two first motors are fixedly connected to one side of the receiving platform, the output ends of the two first motors are respectively fixedly connected to the two first threaded rods.

[0008] Preferably, a first fixing plate is fixedly connected to both ends of the bottom of the receiving platform, a second threaded rod is rotatably connected between the two first fixing plates, the second threaded rod passes through the fixing block and is threadedly connected to the fixing block, and a sliding rod is fixedly connected between the two first fixing plates, the sliding rod passes through the fixing block and is slidably connected to the fixing block.

[0009] Preferably, one end of the receiving platform has an installation groove, and a fixed rod is fixedly connected inside the installation groove. A rotating shaft is rotatably connected inside the fixed rod. One end of the rotating shaft and one end of one of the first threaded rods are fixedly connected to a first bevel gear. The two first bevel gears are meshed with each other. The other end of the rotating shaft and one end of the second threaded rod are fixedly connected to a second bevel gear. The two second bevel gears are meshed with each other. While the first threaded rod rotates to adjust the horizontal position of the robot, the second threaded rod at the bottom of the receiving platform rotates in the same direction, thereby balancing the weight of the top of the receiving platform and preventing the receiving platform from shaking and tilting when the robot is working due to uneven load on the device.

[0010] Preferably, the top of the base has two first sliding grooves, and a sliding plate is slidably connected inside the two first sliding grooves. A second motor is fixedly connected to the top of the base, and a third threaded rod is fixedly installed at the output end of the second motor. The third threaded rod passes through the sliding plate and is threadedly connected to the sliding plate. A second fixing plate is fixedly connected to the top of the base.

[0011] Preferably, the two lifting components are located at opposite ends of one side of the slide plate. Each lifting component includes two first lifting arms and two second lifting arms. One end of each of the two second lifting arms is hinged to the other, and one end of each of the two first lifting arms is hinged to the other. The centers of the two first lifting arms are rotatably connected to the centers of the two second lifting arms. One end of one first lifting arm is hinged to a second fixed plate, and the other first lifting arm is hinged to a movable plate. One end of one second lifting arm is hinged to the slide plate, and a slider is fixedly connected to the side of one end of the other second lifting arm.

[0012] Preferably, the bottom sides of the receiving platform are fixedly connected to limit plates, and the two limit plates are provided with second sliding grooves, and the two sliders are respectively slidably connected inside the two second sliding grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, the rotation of the third threaded rod is controlled during operation, thereby driving the receiving platform at the top of the lifting assembly to rise or fall. The robot can be raised or lowered at any height according to the needs of the painting robot, thereby increasing the robot's working range.

[0015] 2. In this application, when the first threaded rod rotates and drives the robot to move to one side of the receiving platform, the second threaded rod simultaneously rotates in the opposite direction, driving the counterweight block at its bottom to move to the other side of the receiving platform. This ensures that the center of gravity of the receiving platform is always in the middle of the receiving platform when the robot moves on top of it, thereby improving the stability of the receiving platform and preventing the device from being unbalanced when the robot moves to one side of the device. This would prevent the uneven force on the lifting arms on both sides of the bottom of the receiving platform from causing the receiving platform to shake and tilt more when the robot is working, thus affecting the robot's painting work.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 4As shown, this utility model provides a technical solution for a lifting device for a painting robot, including a base 1, a receiving platform 2 on the top of the base 1, two rails 3 fixedly connected to the top of the receiving platform 2, a movable plate 5 slidably connected to the top of the two rails 3, a receiving plate 6 fixedly connected to the top of the movable plate 5, a fixing block 13 at the bottom of the receiving platform 2, a counterweight block 15 fixedly connected to the bottom of the fixing block 13, a placement groove adapted to the counterweight block 15 on the top of the base 1, two lifting components between the base 1 and the receiving platform 2, and the fixing block 13 and the counterweight block 15 are fixed by bolts. The worker can adjust and replace the counterweight block 15 according to the weight of the robot.

[0024] Both tracks 3 are rotatably connected to first threaded rods 4. The two first threaded rods 4 pass through both ends of the moving plate 5 and are threadedly connected to the moving plate 5. Two first motors 25 are fixedly connected to one side of the receiving platform 2. The output ends of the two first motors 25 are fixedly connected to the two first threaded rods 4 respectively.

[0025] The bottom ends of the receiving platform 2 are fixedly connected to the first fixing plate 7. The two first fixing plates 7 are rotatably connected to the second threaded rod 8. The second threaded rod 8 passes through the fixing block 13 and is threadedly connected to the fixing block 13. The two first fixing plates 7 are fixedly connected to the sliding rod 14. The sliding rod 14 passes through the fixing block 13 and is slidably connected to the fixing block 13.

[0026] One end of the receiving platform 2 has an installation groove, and a fixing rod 9 is fixedly connected inside the installation groove. A rotating shaft 10 is rotatably connected inside the fixing rod 9. One end of the rotating shaft 10 and one end of one of the first threaded rods 4 are both fixedly connected to a first bevel gear 11. The two first bevel gears 11 are meshed with each other. The other end of the rotating shaft 10 and one end of the second threaded rod 8 are both fixedly connected to a second bevel gear 12. The two second bevel gears 12 are meshed with each other. While the first threaded rod 4 rotates to adjust the horizontal position of the robot, the second threaded rod 8 at the bottom of the receiving platform 2 rotates in the same direction, thereby balancing the weight of the top of the receiving platform 2 and preventing the receiving platform 2 from shaking and tilting when the robot is working due to uneven load.

[0027] The top of the base 1 has two first sliding grooves 16, and the slide plate 17 is slidably connected inside the two first sliding grooves 16. The top of the base 1 is fixedly connected to a second motor 26, and the output end of the second motor 26 is fixedly installed with a third threaded rod 18. The third threaded rod 18 passes through the slide plate 17 and is threadedly connected to the slide plate 17. The top of the base 1 is fixedly connected to a second fixing plate 19.

[0028] Two lifting components are located at opposite ends of one side of the slide plate 17. The lifting components include two first lifting arms 20 and two second lifting arms 21. One end of the two second lifting arms 21 is hinged to each other, and one end of the two first lifting arms 20 is hinged to each other. The centers of the two first lifting arms 20 are rotatably connected to the centers of the two second lifting arms 21 respectively. One end of one first lifting arm 20 is hinged to the second fixed plate 19, and the other first lifting arm 20 is hinged to the movable plate 5. One end of one second lifting arm 21 is hinged to the slide plate 17, and a slider 22 is fixedly connected to the side of one end of the other second lifting arm 21.

[0029] Both sides of the bottom of the receiving platform 2 are fixedly connected to limit plates 23. Each of the two limit plates 23 has a second slide groove 24 inside. The two sliders 22 are slidably connected inside the two second slide grooves 24 respectively.

[0030] It should be noted that this utility model is a lifting device for a painting robot. During operation, the painting robot is fixedly installed on the top of the receiving plate 6. Then, the second motor 26 is started, which drives the third threaded rod 18 to rotate. The rotation of the third threaded rod 18 drives the slide plate 17 to move. The movement of the slide plate 17 drives the second lifting arm 21, which is hinged at both ends of the slide plate 17, to move. The first lifting arm 20 of the lifting assembly is hinged to the second lifting arm 21. When one end of the second lifting arm 21 moves toward one end of the first lifting arm 20, the hinge point between the first lifting arm 20 and the second lifting arm 21 moves upward. At this time, the other ends of the second lifting arm 21 and the first lifting arm 20 approach each other and gradually rise, thereby driving the receiving platform 2 at the top of the lifting assembly to rise. When the slide plate 17 drives the second lifting arm 21 away from the first lifting arm 20, the receiving platform 2 descends. By controlling the rotation of the third threaded rod 18, the robot can be raised and lowered to any height according to the needs of the painting robot, thereby improving the robot's working range.

[0031] During the use of the device, the first motor 25 drives the first threaded rod 4 to rotate. The rotation of the first threaded rod 4 can drive the receiving plate 6 to move horizontally on the top of the receiving platform 2 through the moving plate 5, so that the painting robot installed on the receiving plate 6 can move in the horizontal direction. While the first threaded rod 4 rotates, it drives the rotating shaft 10 to rotate via the first bevel gear 11. The rotating shaft 10 drives the second threaded rod 8 to rotate via the second bevel gear 12. At this time, the rotation direction of the second threaded rod 8 is opposite to that of the first threaded rod 4. The outer thread of the second threaded rod 8 is connected to a fixing block 13. When the first threaded rod 4 rotates and drives the robot to move to one side of the receiving platform 2, the second threaded rod 8 rotates in the opposite direction and drives the fixing block 13 and the counterweight block 15 at its bottom to move to the other side of the receiving platform 2. This ensures that the center of gravity of the receiving platform 2 is always in the middle of the receiving platform 2 when the robot moves on the top of the receiving platform 2, thereby improving the stability of the receiving platform 2 and preventing the device from being unbalanced when the robot moves to work on one side of the device. This would cause the lifting arms on both sides of the bottom of the receiving platform 2 to be subjected to inconsistent forces, which would cause the receiving platform 2 to shake and tilt more when the robot is working, thus affecting the robot's painting work.
