Angle-adjustable rotary station for a painting robot

Abstract

This invention relates to the field of robotic painting station technology, and discloses an angle-adjustable rotating station for a painting robot, including a control cabinet. The invention utilizes the trajectory constraint of the elliptical first adjustment groove on the first guide plate to enable the insert cover to autonomously retract and reset synchronously with the circumferential rotation of the positioning cover. This eliminates the need for an additional independent telescopic drive mechanism, relying solely on a mechanical trajectory to achieve flexible telescopic movement. The retraction process is smooth and gentle without rigid impact. During workpiece rotation, the rotation radius can adaptively decrease, effectively reducing the overall footprint of the station and preventing collisions and interference between the workpiece and the painting robot arm or surrounding frames in confined painting workshops, thus improving production line space utilization. Simultaneously, the station rotation and insert cover telescopic movement can be synchronized with a negative pressure positioning structure, providing negative pressure adsorption and fixation of the workpiece throughout the process, further reducing the swaying hazards caused by rotational centrifugal force and telescopic inertial force, ensuring stable workpiece rotation.

Description

Technical Field

[0001] This invention belongs to the field of robotic spraying station technology, specifically, it relates to an angle-adjustable rotating station for a spraying robot. Background Technology

[0002] In automated spraying production lines, rotary stations are the core tooling that works in conjunction with spraying robots to complete all-around spraying of workpieces. They are mainly used to support the workpieces and drive them to rotate circumferentially, thereby achieving spraying processing of workpieces without dead angles.

[0003] Currently, most conventional rotary spraying stations use fixed rotating bases. The workpiece rotates in a fixed radius around the station, and the overall rotation trajectory remains unchanged. This results in a large space occupied by the rotating equipment. In automated spraying workshops with compact layouts and small equipment spacing, rotary stations with fixed rotation radii are prone to collisions and interference between the workpiece and the spraying robot arm or surrounding frame structure during rotation. This severely restricts the layout of spraying production lines in confined spaces, leading to low space utilization and an inability to adapt to the flexible production needs of different sized workspaces.

[0004] To address the issue of excessive space occupied by rotary workstations, some existing technical solutions incorporate electric push rods as telescopic drive components. These push rods push and pull the support platform, altering the workpiece's rotation radius and thus reducing the workstation's footprint. However, during the operation of the spraying station, the workpiece is subjected to continuous centrifugal force generated by circumferential rotation. The electric push rod's start and stop instantaneous movement generates rigid impact thrust and inertial pull. The push rod's start and stop impact force and the rotational centrifugal force combine to create a superposition of forces. These two forces interfere with each other and act synchronously on the workpiece, causing it to shake violently, shift, or even flip on the support platform.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0021] Example 1:

[0022] like Figures 1 to 8 As shown, an angle-adjustable rotating station for a painting robot includes a control cabinet 1. A positioning cover 5 is rotatably mounted on the control cabinet 1. A first guide plate 13 is also fixedly mounted on the control cabinet 1 and placed inside the positioning cover 5. A pair of limiting covers 15 are installed on the side wall of the positioning cover 5. A plug cover 16 is movably inserted inside each limiting cover 15, and a base 17 is installed at the end of the plug cover 16. The base 17 is used to support the workpiece. A drive assembly is also installed on the control cabinet 1. The drive assembly is used to drive the positioning cover 5 and the base 17 to rotate and change the station position. A connecting rod 19 is installed inside the insert cover 16. The end of the connecting rod 19 is connected to the first adjustment groove 21 opened on the first guide plate 13. The first adjustment groove 21 is elliptical. When the insert cover 16 rotates and changes position, the first adjustment groove 21 causes the insert cover 16 to retract and reduce the space occupied by rotation. A negative pressure pipe 26 is installed on the base 17, and the end of the negative pressure pipe 26 is flush with the surface of the base 17. A negative pressure cover 30 is installed inside the limiting cover 15, and the negative pressure cover 30 is connected to the negative pressure pipe 26. A piston 32 is slidably installed inside the negative pressure cover 30, and the piston 32 is connected to the connecting rod 19. During the retraction of the insert cover 16, the piston 32 moves synchronously, and the workpiece is adsorbed and positioned through the negative pressure pipe 26 to prevent the workpiece from shaking during the displacement process.

[0023] like Figures 1 to 8 As shown in the specific embodiment, protrusions are installed at the four corners of the bottom of the control cabinet 1, and threaded rods 2 are screwed onto the bottom of the protrusions. Support blocks 3 are screwed onto the bottom of the threaded rods 2. The cross-sectional area of ​​the support blocks 3 is trapezoidal, and anti-slip grooves are also provided at the bottom of the support blocks 3. A controller 4 is also installed on the control cabinet 1, and the controller 4 is used to control the start and stop of the drive components. An inspection door 37 is also installed on the side wall of the control cabinet 1. The adjustable threaded rods 2 and trapezoidal support blocks 3 are used to level the machine, and the controller 4 provides centralized control of the machine. The inspection door 37 facilitates operation and maintenance, improving the stability of the equipment placement and the convenience of later maintenance.

[0024] like Figures 1 to 8 As shown, the drive assembly further includes a shift motor 10, which is embedded inside the control cabinet 1. An output rod is mounted on the output end of the shift motor 10, and a gear 9 is mounted at the end of the output rod. A rack 8 is mounted on the inner wall of the positioning cover 5, and the rack 8 meshes with the gear 9. The gear 9 and rack 8 meshing transmission method provides smooth transmission and strong load-bearing capacity. The embedded shift motor 10 layout reduces the external space occupied by the equipment and improves the operational safety of the equipment.

[0025] Example 2:

[0026] The difference between the above embodiments and this embodiment is that: Figures 1 to 8 As shown, a positioning rod 11 is fixedly installed at the center of the control cabinet 1. The positioning rod 11 is rotatably connected to the bottom of the positioning cover 5. A slide rail 6 is installed at the bottom of the outer wall of the positioning cover 5. A slide groove 7 is provided on the control cabinet 1, and the slide rail 6 is slidably mounted on the slide groove 7. Both the slide groove 7 and the slide rail 6 are circular. By using the circular slide rail 6 and the slide groove 7 for limiting and positioning, and with the guidance and support of the central positioning rod 11, a higher degree of concentricity of the circumferential rotation of the positioning cover 5 is ensured, and vibration during the rotation process is avoided.

[0027] like Figures 1 to 8 As shown in the specific embodiment, a fixed seat 18 is installed inside the cavity of the insert cover 16. A connecting rod 19 is rotatably installed inside the fixed seat 18. A slide rod 20 is installed at one end of the connecting rod 19, and the end of the slide rod 20 is slidably connected to the surface of the first adjusting groove 21. The fixed seat 18 provides a rotation fulcrum for the connecting rod 19, which, together with the slide rod 20, slides against the groove, ensuring smooth angle switching of the connecting rod 19 and reducing mechanical movement jamming and frictional wear.

[0028] like Figures 1 to 8 As shown, furthermore, the end of the connecting rod 19 is rotatably connected to the side wall of the insert cover 16. A limit plate 22 is installed on the other end of the connecting rod 19. A pair of limit seats 23 are also installed on the outer side wall of the insert cover 16. A locking bolt 24 is screwed through and screwed onto the pair of limit seats 23. The locking bolt 24 is movably connected to the limit plate 22. The locking bolt 24 is used to adjust the angle of the connecting rod 19. A handle 25 is installed at the end of the limit plate 22. The handle 25 is equipped with an anti-slip groove. The angle is locked by the cooperation of the locking bolt 24 and the limit plate 22. With the handle 25 with anti-slip groove, it is convenient for the operator to quickly adjust and lock. The manual adjustment operation is convenient and labor-saving.

[0029] like Figures 1 to 8 As shown, a second guide plate 14 is further installed on the positioning rod 11. The second guide plate 14 is placed inside the positioning cover 5. A second adjustment groove 36 is provided at the bottom of the second guide plate 14, and the second adjustment groove 36 is arc-shaped. The second adjustment groove 36 is used to engage with the connecting rod 19 after it rotates 180 degrees, so as to ensure that the insert cover 16 does not retract during rotation. A base plate 12 is installed at the end of the positioning rod 11, and the base plate 12 is placed outside the positioning cover 5. The addition of the arc-shaped second adjustment groove 36 in this section can lock the extension stroke of the insert cover 16, realize constant radius rotation operation, adapt to the spraying conditions of spacious workshops, and broaden the scope of application.

[0030] Example 3:

[0031] The difference between the above embodiments and this embodiment is that: Figures 1 to 8 As shown, the negative pressure tubes 26 are arranged in a ring on the base 17. A rubber pad 27 is installed on the top of the negative pressure tubes 26, and a connecting cover 28 is installed at the bottom of the insert cover 16, with the connecting cover 28 communicating with the negative pressure tubes 26. A flexible hose 29 is installed at the bottom of the connecting cover 28, and the end of the flexible hose 29 communicates with the negative pressure cover 30. A connecting frame 31 is installed on the negative pressure cover 30, and the end of the connecting frame 31 is welded to the side wall of the limiting cover 15. The ring-arranged negative pressure tubes 26, combined with the flexible hose 29, accommodate the expansion and contraction of the insert cover 16. The rubber pad 27 improves the sealing of the contact surface, effectively preventing negative pressure leakage and ensuring adsorption stability.

[0032] like Figures 1 to 8 As shown, in a specific embodiment, a push rod 33 is installed on the piston 32, and the push rod 33 passes through the negative pressure cover 30. A synchronization frame 34 is installed at the end of the push rod 33, and the synchronization frame 34 is rotatably connected to the connecting rod 19. A pair of baffles 35 are installed on the connecting rod 19, and the pair of baffles 35 cover both sides of the synchronization frame 34.

[0033] The implementation principle of the adjustable-angle rotary station for a painting robot according to the present invention is as follows: First, the controller 4 on the side wall of the control cabinet 1 controls the start-up, shutdown, and operation sequence of the electrical components of the whole machine. The threaded rods 2 and trapezoidal support blocks 3 at the four corners of the bottom of the control cabinet 1 work together to adjust the level of the whole machine by rotating the threaded rods 2. The anti-slip grooves at the bottom of the support blocks 3 can improve the stability of the equipment and prevent the whole machine from shifting and shaking during the spraying operation. Subsequent equipment inspection and maintenance can be completed by opening the maintenance door 37 on the side wall of the control cabinet 1, ensuring the convenience of equipment operation and maintenance.

[0034] When the equipment performs a workstation rotation switching operation, the shift motor 10 built into the control cabinet 1 starts. The shift motor 10 drives the output rod and the gear 9 at the end to rotate synchronously. Relying on the meshing transmission relationship between the gear 9 and the rack 8 on the inner side wall of the positioning cover 5, the positioning cover 5 is driven to rotate around the positioning rod 11 at the center of the control cabinet 1. At the same time, the circular slide rail 6 at the bottom of the outer side wall of the positioning cover 5 slides synchronously along the corresponding circular slide groove 7 at the top of the control cabinet 1. The slide rail 6 and the slide groove 7 cooperate to provide radial limit and support for the positioning cover 5, effectively counteracting the radial force generated by the gear and rack transmission, ensuring that the rotation of the positioning cover 5 is smooth and without deviation. The base plate 12 at the top of the positioning rod 11 can further limit the axial position of the positioning cover 5, preventing the positioning cover 5 from moving up and down.

[0035] During the synchronous circumferential rotation of the positioning cover 5, the two side limit covers 15, the insert cover 16, and the base 17 to switch work positions, one end of the connecting rod 19 is rotatably assembled into the inner cavity of the insert cover 16 through the fixed seat 18, and the slide rod 20 at the other end of the connecting rod 19 slides against the elliptical first adjustment groove 21 on the surface of the first guide plate 13. Relying on the trajectory characteristics of the elliptical first adjustment groove 21, the insert cover 16 automatically retracts into the limit cover 15 while revolving with the positioning cover 5, effectively reducing the radial space occupied by the entire rotating work position, reducing the risk of collision and interference between the workpiece and the surrounding structure when the painting robot is working, and adapting to the use requirements of narrow painting work space.

[0036] During the entire process of the insert cover 16 revolving around the positioning cover 5 and simultaneously retracting and resetting itself, the workpiece is continuously subjected to the dual interference of centrifugal force and the inertial force of the telescopic structure, resulting in an extremely unstable overall force state. Without the support of the positioning structure, the workpiece is very likely to slide, tilt, or even fall off the surface of the base 17, directly affecting the spraying accuracy. Therefore, when the insert cover 16 retracts and resets, the connecting rod 19 drives the piston 32 inside the negative pressure cover 30 to slide synchronously in a straight line through the synchronous frame 34 and the top rod 33. The movement of the piston 32 will change the internal cavity volume of the negative pressure cover 30. After the cavity volume changes, a stable negative pressure environment is quickly formed. The negative pressure airflow is sequentially conducted through the hose 29 and the connecting cover 28 to the negative pressure pipe 26 distributed in a ring on the surface of the base 17. The workpiece to be sprayed is firmly adsorbed by the continuous negative pressure suction. The rubber pad 27 mounted on the outside of the negative pressure pipe 26 at the top of the base 17 can tightly fit the bottom surface of the workpiece, improve the sealing effect of the contact surface, and avoid negative pressure leakage leading to attenuation of adsorption force and positioning failure.

[0037] Depending on the size of the spraying space and the differences in workpiece specifications, the retraction motion of the insert 16 can be activated according to the working conditions, thereby matching two different rotary working modes.

[0038] When the spraying space is confined and interference with equipment needs to be avoided, and the insertion cover 16 must be retracted to reduce the radius of rotation, the slide rod 20 continuously slides against the elliptical first adjustment groove 21 on the first guide plate 13. Relying on the change in the diameter of the elliptical groove, the insertion cover 16 synchronously completes reciprocating retraction and reset actions during circumferential rotation. This, combined with the negative pressure adsorption structure mentioned earlier, counteracts the force fluctuations caused by the extension and retraction motion. When the spraying space is sufficient and the insertion cover 16 does not need to retract for compensation, and it is desired to keep the radius of rotation of the base 17 constant and avoid additional workpiece shaking interference caused by repeated extension and retraction, the locking bolt 24 on the limit seat 23 must be loosened first to release the limit plate 22. And the angle of the connecting rod 19 is locked. Then the operator holds the handle 25 and drives the connecting rod 19 to rotate as a whole, so that the slide rod 20 is disengaged from the first adjustment groove 21 of the first guide plate 13, and then switched to be embedded in the second adjustment groove 36 with an arc shape at the bottom of the second guide plate 14 on the positioning rod 11. Finally, the locking bolt 24 is tightened to complete the positioning and locking. The radial dimension of the arc structure of the second adjustment groove 36 does not change. The slide rod 20 will not produce radial displacement during the sliding along the groove, which completely restricts the retraction action of the insert 16, allowing the base 17 to maintain a fixed radius and rotate smoothly, further reducing the stress disturbance of the workpiece, and adapting to stable and continuous spraying operations in large spaces.

[0039] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
