Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating testing technology, and more specifically to a coating testing robot. Background Technology
[0002] In the decoration process, brushes are widely used as an important painting tool due to their flexibility. However, due to the influence of the medium being painted and the material of the brush itself, the application areas and painting effects of different brushes and mediums vary significantly. Therefore, it is necessary to test the combination of the two to obtain better results.
[0003] To address this, current coating testing machines generally connect a brush dipped in the medium to a three-dimensional moving device. The three-dimensional moving device then moves the brush across the test paper to achieve the testing effect. However, due to differences in the dipping method, brushing angle, and pressure applied by different operators during actual use, the accuracy of the test results is poor, and therefore needs improvement.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.
[0026] like Figure 1-2 As shown, a coating test robot includes: a frame 1, a test surface 2 on the frame 1, the test surface 2 being a plate, and a take-up roller 3 on one side of the frame 1 corresponding to the test surface 2. In this embodiment, a handwheel 4 is provided at one end of the take-up roller 3, and the take-up action is achieved by manually rotating the handwheel 4. In another embodiment, one end of the take-up roller 3 can be driven by a motor to achieve automatic take-up.
[0027] Furthermore, the frame 1 is also equipped with a feeding roller 5. The feeding roller 5 and the winding roller 3 are respectively arranged on both sides of the test surface 2. When in use, the test paper roll is placed on the feeding roller 5, and one end of the test paper passes over the test surface 2 and is wound on the winding roller 3.
[0028] By using the feed roller 5 in conjunction with the take-up roller 3, the test paper can be made more stable on the test surface 2, reducing wrinkles and facilitating testing.
[0029] Furthermore, the frame 1 is equipped with a lifting assembly 6 and is connected to the test surface 2 through the lifting assembly 6. The lifting assembly 6 is used to drive the test surface 2 to rise and fall.
[0030] Specifically, the lifting component 6 is a lifting cylinder, which is installed inside the machine body, and the lifting cylinder end is connected to the test surface 2.
[0031] By setting up the lifting component 6, the height of the test surface 2 can be adjusted according to the test requirements.
[0032] Furthermore, the frame 1 is provided with a paper pressing device 7 corresponding to the test surface 2. The paper pressing device 7 includes at least two symmetrically arranged paper pressing surfaces. In this embodiment, the number of paper pressing surfaces is 4, and the 4 paper pressing surfaces are arranged on the side of the test surface 2. Two of the paper pressing surfaces are connected to the test surface 2, and the other two paper pressing surfaces are arranged on the frame 1.
[0033] Specifically, the paper pressing device 7 also includes a control cylinder connected to the paper pressing surface. During use, the control cylinder controls the raising and lowering of the paper pressing surface to achieve the effect of fixing and loosening the test paper on the test surface 2.
[0034] Furthermore, the frame 1 is provided with a material cylinder 8 and a liquid level monitoring device 9 is provided corresponding to the material cylinder 8. The liquid level monitoring device 9 is used to monitor the liquid level height of the medium in the material cylinder 8 in order to determine the remaining capacity.
[0035] Furthermore, the rack 1 is provided with a vision unit 10 corresponding to the test surface 2. The vision unit 10 is used to acquire images of the test surface 2. In this embodiment, the vision unit 10 is specifically a camera, which is set above the test surface 2 and the lens corresponds to the test surface 2. The setting of the vision unit 10 can facilitate the acquisition and storage of images of each test for subsequent comparison and reference.
[0036] Furthermore, it also includes a gripper unit 11 and a three-dimensional moving mechanism 12. The three-dimensional moving mechanism 12 is disposed on the frame 1 and connected to the gripper unit 11. The three-dimensional moving mechanism 12 is used to drive the gripper unit 11 to move in three dimensions. The three-dimensional moving mechanism 12 is existing technology and specifically adopts a motor-driven method in conjunction with a slide rail, which will not be described in detail here.
[0037] Specifically, the gripper unit 11 includes a fixed plate 13, a mounting plate 14, and a fixed gripper 15. The fixed plate 13 is connected to the three-dimensional moving mechanism 12, specifically to the Z-axis drive component in the three-dimensional moving mechanism 12. The fixed gripper 15 is fixedly mounted on the mounting plate 14. In this embodiment, the fixed gripper 15 is specifically a pneumatic gripper, which includes two symmetrically arranged gripper arms. The two gripper arms are controlled by air pressure to move closer or further apart to achieve gripping and releasing. This pneumatic gripper is existing technology and will not be described in detail here. A coating device 16 is provided between the fixed plate 13 and the mounting plate 14 and is connected to each other through the coating device 16. The coating device 16 includes at least two drive shafts, which are perpendicular to each other and are used to drive the mounting plate 14 to rotate around the corresponding drive shaft as the axis.
[0038] By setting up two drive shafts, the relative angle and position of the mounting plate 14 and the fixed plate 13 can be adjusted, which in turn works with the three-dimensional moving mechanism 12 to improve the realism of the simulation and simulate the brushing effect of the brush at different angles and directions.
[0039] Furthermore, a weighing module 17 is provided on the mounting plate 14, and a connector 18 is provided at the detection end of the weighing module 17 and connected to the brush through the connector 18.
[0040] During use, the initial weight of the brush is recorded by the weighing module 17. The brush is then moved to the material cylinder 8 by the three-dimensional moving mechanism 12. At this time, the brush angle and direction can be adjusted by the drive shaft, and the three-dimensional moving mechanism 12 is used to complete the dipping action. The weighing module 17 can record the amount of material dipped by the brush during this dipping action. The brush is then moved to the test surface 2 by the three-dimensional moving mechanism 12. The brushing effect at different angles, distances, and directions is achieved by the three-dimensional moving mechanism 12 and the two drive shafts. After a single section of brushing is completed, the brush is separated from the test paper, and the change in brush weight is detected by the weighing module 17 to complete the detection of the amount of medium consumed.
[0041] During the weighing module 17's testing process, the pneumatic gripper releases its grip on the brush, allowing the weighing module 17 to complete the weight test of the brush via the connector 18. After the test is completed, the pneumatic gripper re-grips the brush for testing.
[0042] Specifically, the coating device 16 includes a first motor 19 and a second motor 20. In this embodiment, both the first motor 19 and the second motor 20 are servo motors. The two drive shafts are the output shafts of the first motor 19 and the second motor 20, respectively. The output end of the first motor 19 is provided with a reducer 22 and is connected to the rotating base 21 through the reducer 22. The first motor 19 is used to drive the rotating base 21 to rotate. The second motor 20 is connected to the rotating base 21, and the output end of the second motor 20 is connected to the mounting plate 14 and is used to drive the mounting plate 14 to rotate.
[0043] The first motor 19 and the second motor 20 are configured to achieve two-axis drive of the mounting plate 14, thereby ensuring the flexibility of the mounting plate 14.
[0044] Furthermore, the output end of the second motor 20 is hinged to the mounting plate 14, and the output end of the second motor 20 is provided with a fixed clamping block 23 and a regulating cylinder 24 is connected through the fixed clamping block 23. The output end of the regulating cylinder 24 is hinged to the mounting plate 14, and the regulating cylinder 24 extends and retracts to drive the mounting plate 14 to swing relative to the second motor 20.
[0045] By adjusting the hinge of the cylinder 24 in conjunction with the mounting plate 14, the tilt of the mounting plate 14 can be controlled, thereby further expanding the adjustment range of the mounting plate 14 and improving the simulation realism.
[0046] Preferably, connector 18 is a hook.
[0047] The hook connects to the brush through pre-drilled holes, making it easy to install and remove the brush.
[0048] Preferably, a third motor 25 is provided on the mounting plate 14, and the output end of the third motor 25 is connected to the weighing module 17.
[0049] Specifically, the third motor 25 is a servo motor. The output end of the servo motor is equipped with a rotating shaft 26 and is connected to the weighing module 17 through the rotating shaft 26. The rotating shaft 26 is equipped with a buffer spring 27, which can prevent the pneumatic gripper from damaging the weighing module 17 when it grips the brush.
[0050] The addition of a third motor 25 further enhances the brush's mobility, thereby improving the realism of the simulation test.
[0051] Preferably, the fixed plate 13 is provided with a limit switch 28, and the rotary seat 21 is provided with a detection plate 29 corresponding to the limit switch 28.
[0052] The limit switch 28 can prevent the rotary table 21 from moving excessively and causing a collision, thereby improving test safety.
