When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0034] See also Figure 1-Figure 10 In an embodiment of the present invention, a UV plate surface spraying material wear resistance detection device comprises a base 1 and a horizontal platform 3 arranged on the base 1, wherein the horizontal platform 3 is used to place the UV plate and can be raised and lowered on the base 1; the UV plate surface spraying material wear resistance detection device also includes: a horizontal plate 4, which is movably arranged on the base 1 and connected to a path switching mechanism installed on the side of the base 1, wherein the horizontal plate 4 is provided with a guide groove, wherein a first slider 6, a second slider 7 and a follower plate 8 are slidably engaged in the guide groove, wherein the follower plate 8 is located between the first slider 6 and the second slider 7, and is connected to a wear simulation mechanism for grinding the surface of the UV plate, wherein the first slider Block 6 and the second slider 7 are respectively connected to the first uniform pulling mechanism and the second uniform pulling mechanism arranged on the cross plate 4, and two groups of one-way connection mechanisms are also arranged between the first slider 6 and the follower plate 8; an extension rod 23 is movably arranged on the base 1 and is located above the cross platform 3, and an assembly plate 21 is slidably provided on the extension rod 23, and the wear simulation mechanism is installed on the assembly plate 21. The extension rod 23 is connected to the transverse driving mechanism arranged on the side of the base 1, and the transverse driving mechanism can drive the extension rod 23 to drive the wear simulation mechanism to move along the length direction of the cross plate 4, and the movement paths of the extension rod 23 and the cross plate 4 are perpendicular.

[0035] Furthermore, a plurality of cylinders 2 are installed on the base 1, and the cylinders 2 are used to lift the horizontal platform 3. When performing the inspection, the UV plate is stably fixed on the horizontal platform 3, and then the cylinders 2 drive the horizontal platform 3 to rise, so that the surface of the UV plate contacts the first slider 6, the second slider 7 and the bottom of the wear simulation mechanism; secondly, the first uniform pulling mechanism has the same structure as the second uniform pulling mechanism, and a specific description is given for the first uniform pulling mechanism, which includes a first driving motor 9 installed on the horizontal plate 4 and a first driving motor 9 fixed on the horizontal plate 4. The line roller 10 at the end of the output shaft of the first driving motor 9 is provided with a pull rope, one end of the pull rope is pulled out from the line roller 10, and passes around the guide wheel 5 provided on the horizontal plate 4 to connect with the first slider 6. During the detection process, the first slider 6 and the second slider 7 are pulled by the pull rope and can slide linearly on the surface of the UV plate. In the present application, corresponding sensor components are also provided to measure the friction coefficient of the UV plate surface before and after polishing when the first slider 6 and the second slider 7 slide, so as to compare the data and evaluate the durability and wear resistance of the coating.

[0036] Specifically, the moving paths of the first slider 6, the second slider 7 and the follower plate 8 are consistent. During the inspection, the first slider 6 slides first to measure the surface friction coefficient of the UV plate before polishing. Then, the wear simulation mechanism is activated to polish the moving path of the first slider 6 on the UV plate. Finally, the second slider 7 slides to measure the surface friction coefficient of the UV plate after polishing. Subsequently, the first slider 6, the second slider 7 and the follower plate 8 are reset, and the wear simulation mechanism is subjected to downward pressure, and the subsequent polishing intensity of the UV plate surface is increased. The path switching mechanism works to drive the cross plate 4 to move a distance along the width direction of the cross table 3 to change the subsequent measurement path. In summary, the entire inspection process is divided into multiple paths, and on each inspection path, the wear simulation mechanism has a different polishing intensity on the UV plate surface. Therefore, after the inspection is completed, multiple sets of measurement data under different polishing parameters can be obtained, thereby realizing the diversification of the inspection results and making the final evaluation results more valuable for reference.

[0037] Please refer again Figure 8The wear simulation mechanism includes a second drive motor 22 mounted on the assembly plate 21 and a grinding disc 15 connected to the output shaft of the second drive motor 22 through an elastic telescopic structure, the grinding disc 15 coincides with the central axis of the output shaft of the second drive motor 22, and the elastic telescopic structure passes through the follower plate 8. The elastic telescopic structure includes a drive pipe 16 coaxially fixed to the output shaft of the second drive motor 22 and a telescopic shaft 17 slidably fitted with the drive pipe 16, a circular hole adapted to the drive pipe 16 is provided on the follower plate 8, the drive pipe 16 passes through the circular hole and is slidably connected to the follower plate 8, the telescopic shaft 17 is fixedly connected to the grinding disc 15, and the end away from the grinding disc 15 is connected to an elastic connector provided inside the drive pipe 16. The elastic connector includes a boss 18 and a second cylindrical spring 20 slidably disposed inside the driving pipe 16, one end of the telescopic shaft 17 away from the grinding disc 15 is fixed to the boss 18, one end of the second cylindrical spring 20 is connected to the boss 18, and the other end is connected to the inner wall of the driving pipe 16. Two bosses 1801 are fixedly disposed on the outer periphery of the boss 18, and a strip groove 1601 adapted to the boss 1801 is disposed on the driving pipe 16, and the boss 1801 extends into the strip groove 1601.

[0038] During detection, the air cylinder 2 drives the horizontal table 3 to rise, so that the surface of the UV plate abuts against the bottom of the grinding disc 15, and the second cylindrical spring 20 is compressed. Therefore, under the action of the elastic force of the second cylindrical spring 20, the grinding disc 15 has a certain pressure on the surface of the UV plate, and the second driving motor 22 works to drive the driving pipe 16 to rotate. Then, the driving pipe 16 can drive the boss 18, the telescopic shaft 17 and the grinding disc 15 to rotate through the boss 1801, so that the grinding disc 15 grinds the surface of the UV plate. Correspondingly, the transverse driving mechanism drives the extension rod 23 to drive the assembly plate 21 to move along the length direction of the horizontal plate 4, so that the grinding disc 15 moves on the surface of the UV plate along the sliding path of the first slider 6. Subsequently, the path switching mechanism drives the When the transverse plate 4 moves along the width direction of the horizontal platform 3 to change the detection path, the transverse plate 4 can drive the grinding disc 15 to switch to a new detection path through the follower plate 8, and the assembly plate 21 slides on the extension rod 23; in the latter part of the stroke of the first slider 6, the second slider 7 and the follower plate 8 resetting, the extension rod 23 will move downward, and accordingly, the assembly plate 21, the second drive motor 22 and the drive pipe 16 move downward together. Since the grinding disc 15 is in contact with the surface of the UV plate, the grinding disc 15 remains stationary, and the compression amount of the second column spring 20 increases, that is, the pressure of the grinding disc 15 on the surface of the UV plate increases, and the grinding force of the grinding disc 15 on the surface of the UV plate is subsequently increased to achieve diversification of the detection results, so that the final evaluation result is more valuable for reference.

[0039] Please refer again Figure 2 , Fig. 9 as well as Fig.10 The transverse driving mechanism includes a first guide rail 31 fixed on the base 1 and a first movable block 32 slidably engaged with the first guide rail 31. A guide plate 24 is fixedly mounted on the first movable block 32, and a lifting plate 25 is slidably disposed in the guide plate 24. The first movable block 32 is connected to a first threaded driving assembly mounted on the base 1, the extension rod 23 is fixed to the lifting plate 25, and a height switching assembly connected to the lifting plate 25 is disposed on the first movable block 32. The height switching assembly is triggered when the first slider 6, the follower plate 8, and the second slider 7 return along the detection path.

[0040] The height switching assembly includes a screw rod 26 rotatably mounted on the first movable block 32 and a threaded sleeve 27 sleeved on the screw rod 26 and threadedly connected to the screw rod 26, and the threaded sleeve 27 is fixedly connected to the lifting plate 25. A ratchet 29 is also rotatably mounted on the first movable block 32, a ratchet plate 30 matched with the ratchet 29 is fixedly mounted on the base 1, and the rotating shaft of the ratchet 29 is connected to the screw rod 26 through a transmission belt 28.

[0041] The first movable block 32 slides toward one side along the first guide rail 31. When the grinding disc 15 grinds the surface of the UV plate during movement, the ratchet 29 will not rotate when passing through the ratchet plate 30. In the latter stroke of the grinding disc 15 after resetting, the ratchet 29 will pass through the ratchet plate 30 again. At this time, the ratchet 29 will rotate. Therefore, the rotating shaft of the ratchet 29 drives the screw rod 26 to rotate through the transmission belt 28, so that the threaded sleeve 27 is threadedly matched with the screw rod 26. The threaded sleeve 27 drives the lifting plate 25 to slide downward in the guide plate 24. Accordingly, the extension rod 23 The assembly plate 21 is pressed down, so that the compression amount of the second cylindrical spring 20 increases, and the subsequent grinding force of the grinding wheel 15 on the surface of the UV plate increases; it should be supplemented that the threaded sleeve 27 is fixed to the lifting plate 25 by the connecting piece 2701, and the side of the guide plate 24 facing the threaded sleeve 27 is provided with a groove for the movement of the connecting piece 2701; in addition, in order to facilitate the next use of the device, the threaded sleeve 27 should be reset after the inspection work is completed. For this purpose, a knob is also fixed at the upper end of the screw rod 26. By turning the knob, the threaded sleeve 27 drives the lifting plate 25 to move up and reset.

[0042] Please refer again Figure 5 A gap is reserved between the first slider 6 and the follower plate 8, the follower plate 8 abuts against the second slider 7, and the sliding stroke of the follower plate 8 on the transverse plate 4 is greater than the sliding stroke of the first slider 6 on the transverse plate 4. A first protruding block 601 and a second protruding block 701 are fixedly provided on the sides of the first slider 6 and the second slider 7, respectively, and a first through slot 401 and a second through slot 402 are provided on both sides of the transverse plate 4 for the first protruding block 601 and the second protruding block 701 to move.

[0043] The one-way connection mechanism includes a connection bar 11 fixed on the follower plate 8, two columns 12 slidably arranged on the connection bar 11, and a locking member 13 fixed to the two columns 12, the outer periphery of the column 12 is sleeved with a first cylindrical spring 19, and the two ends of the first cylindrical spring 19 are respectively connected to the locking member 13 and the connection bar 11. The locking member 13 is arranged in an inverted triangle shape, and a limiting protrusion 14 is fixed on the first slider 6, and a card slot 1402 adapted to the locking member 13 is provided on the limiting protrusion 14, and an inclined surface 1401 matched with the locking member 13 is also provided on the side of the limiting protrusion 14 facing the locking member 13.

[0044] The two sliding directions of the first slider 6, the second slider 7 and the follower plate 8 on the transverse plate 4 are divided into a detection process (i.e., the first slider 6 and the second slider 7 slide, the friction coefficient is measured, and the grinding disc 15 grinds the surface of the UV plate) and a reset process; during the detection process, the first slider 6 slides first to measure the friction coefficient of the UV plate before grinding, and then the follower plate 8 and the second slider 7 move at the same time, with the grinding disc 15 in front and the second slider 7 in the back. Therefore, according to the sliding of the second slider 7, the friction coefficient of the UV plate after grinding can be measured. Since the sliding stroke of the follower plate 8 on the transverse plate 4 is greater than the sliding stroke of the first slider 6 on the transverse plate 4, the initial gap between the follower plate 8 and the first slider 6 will become smaller in the latter stroke of the follower plate 8, and the locking member 13 and the tilting member 13 will be locked. The inclined surface 1401 contacts and slides together, the locking piece 13 gives way laterally, the column 12 slides upward on the connecting strip 11, the first column spring 19 is compressed, and then the locking piece 13 is stuck in the slot 1402; during the resetting process, the follower plate 8 can push the second slider 7 to move and reset together, and pull the first slider 6 to reset through the connecting strip 11, the locking piece 13 and the limiting protrusion 14. After the first protruding block 601 abuts against the end of the first through groove 401, the first slider 6 stops sliding and the resetting process is completed. At this time, the resetting process of the follower plate 8 has not been completed. As the follower plate 8 continues to move, the locking piece 13 cooperates with the limiting protrusion 14 and gives way upward. The locking piece 13 disengages from the slot 1402, and the gap between the follower plate 8 and the first slider 6 reappears, and the follower plate 8 completes the resetting process.

[0045] It should be emphasized that the first drive motor 9 does not include a holding brake, so that during the resetting process, the follower plate 8 can directly push the second slider 7 to reset, and through the cooperation between the locking member 13 and the limiting protrusion 14, the follower plate 8 can also drive the first slider 6 to reset without manual intervention.

[0046] Please refer again Figure 2 The path switching mechanism includes a second guide rail 34 fixed to the side of the base 1 and a second movable block 35 slidably engaged on the second guide rail 34. The second movable block 35 is fixedly connected to the cross plate 4 through a connecting arm 33, and is also connected to a second threaded drive assembly provided on the base 1.

[0047] In detail, the first threaded drive assembly has the same structure as the second threaded drive assembly. The second threaded drive assembly is described in detail, which includes a threaded rod rotatably mounted on the base 1 and a servo motor mounted on the base 1. The threaded rod is connected to the output end of the servo motor, and the threaded rod also passes through the second movable block 35. The second movable block 35 is threadedly connected to the threaded rod. The threaded rod is used to realize the movement of the cross plate 4 and the movement of the grinding disc 15, which can effectively improve the stability of the driving accuracy.
