[0042] Reference Figure 3 , Figure 4 and Figure 5 , the frame 1 is provided with a first track 11 and a second track 12 which are parallel to each other, and the driving member 3 is used to transport the bearing plate 2 along the length direction of the first track 11 and the second track 12; a notch is provided on the first track 11 for the lifting platform 54 to penetrate and insert, and the detection station 111 is the position of the lifting platform 54. A magnet sheet is provided on the lower surface of the bearing plate 2, and an adsorption iron sheet for magnetic adsorption with the magnet sheet is provided on the upper surface of the driving plate 31, the first track 11, the second track 12 and the lifting platform 54.

[0043] Reference Figure 1 and Figure 3The first linkage component 55 specifically includes a first linkage gear 551, a linkage plate 552, a second linkage gear 553 and a first linkage rack 554; the first linkage gear 551 is fixedly sleeved on the rotating shaft rotatably connected to the rotating frame 51 and the frame 1, the second linkage gear 553 is rotatably connected to one side of the frame 1 close to the lifting platform 54, the first linkage rack 554 is connected to the side wall of the lifting platform 54 and meshes with the second linkage gear 553, the linkage plate 552 is slidably connected to the frame 1 in a direction parallel to the lifting direction of the lifting platform 54, and the side wall of the linkage plate 552 is provided with a second tooth groove meshing with the first linkage gear 551, and a third tooth groove meshing with the second linkage gear 553. When the driving motor 52 is not started, the pressing rod 53 is located away from the detection station 111. When the driving motor 52 is started to drive the rotating frame 51 to rotate and the pressing rod 53 moves toward the detection station 111, the first linkage gear 551 and the second linkage gear 553 rotate and the linkage plate 552 moves downward, so that the first linkage rack 554 drives the lifting platform 54 to move upward, so that the lifting platform 54 and the pressing rod 53 are close to each other, and finally the pressing rod 53 presses the paper tape against the surface of the product to be tested that is moved to the lifting platform 54.

[0044] Reference Figure 4 , Figure 5 and Figure 6 The driving member 3 includes a driving plate 31, a lifting member 32, a sliding member 33 and a second linkage member 34. There is a driving plate 31 corresponding to each of the first track 11 and the second track 12. Accordingly, a clearance groove 541 for the driving plate 31 to move is provided on the upper surface of the lifting platform 54. A plurality of clamping blocks 311 are integrally formed on the upper surface of each driving plate 31 along its length direction, and adjacent clamping blocks 311 form a space for a single bearing platform 2 to be inserted.

[0045] The second linkage component 34 includes a linkage frame 341, a second linkage rack 342 and a third linkage gear 343; the linkage frame 341 is slidably connected to the lower surface of the two driving plates 31, and the driving end of the lifting component 32 is connected to the lower surface of the linkage frame 341 to drive the linkage frame 341 to rise and fall. Specifically, the lifting component 32 can be a cylinder arranged on the frame 1. The sliding component 33 can be a motor embedded in the upper surface of the linkage frame 341, and the driving end of the motor is fixedly inserted on the upper surface of the third linkage gear 343, so that the third linkage gear 343 is rotatably connected to the linkage frame 341, and the second linkage rack 342 is arranged one by one with the driving plate 31, and is connected to the side wall of the corresponding driving plate 31 along the length direction of the corresponding driving plate 31, and the two second linkage racks 342 are both meshed with the third linkage gear 343, so that when the third linkage gear 343 rotates, the moving directions of the two driving plates 31 are opposite.

[0046] The driving process of the driving member 3 of the present application is as follows: when the lifting component 32 is not started, the driving plate 31 and the clamping block 311 are both located below the first track 11 and the second track 12; when the lifting component 32 is started to drive the linkage frame 341 to simultaneously drive the two driving plates 31 to move up to a specified height, the supporting platform 2 is completely moved to above the first track 11, the second track 12, and the lifting platform 54 under the lifting action of the driving plate 31, and then the driving plate 31 is driven by the sliding component 33 to move a specified distance in a direction parallel to the length direction of the driving plate 31, and the specified distance is equal to the distance between two adjacent clamping blocks 311. Then, the lifting component 32 drives the linkage frame 341 to simultaneously drive the two driving plates 31 to move down to a specified height and reset, so that the load-bearing platform 2 moves down to contact the first track 11 or the second track 12 or the lifting platform 54. At this time, the driving plate 31 and the clamping block 311 are moved below the first track 11 and the second track 12 or inserted into the clearance groove 541 of the lifting platform 54, and at this time, a gap is reserved between the driving plate 31 and the bottom of the clearance groove 541, and the gap is the gap for the lifting platform 54 to move up when driven by the second linkage component 34. When the lifting platform 54 is driven by the second linkage component 34 to move up to a predetermined height, the position relationship of the driving plate 31 relative to the clearance groove 541 is as follows: Figure 2 shown.

[0047] Reference Figure 4 and Figure 5 , each bearing platform 2 is provided with a connecting frame 21. In the embodiment of the present application, there are two connecting frames 21 on each bearing platform 2, and each connecting frame 21 is provided with a pressing plate 23 and a reset spring 22. The reset spring 22 is sleeved on the connecting frame 21 and connected between the connecting frame 21 and the pressing plate 23, so that the pressing plate 23 is slidably connected to the connecting frame 21 with the help of the reset spring 22. A pad 231 is also slidably connected to the side of the pressing plate 23 facing the upper surface of the bearing platform 2. The sliding direction of the pad 231 is the direction of approaching or moving away from the bearing platform 2. A buffer layer 232 is also connected to the side surface of the pad 231 facing the bearing platform 2. The buffer layer 232 can be made of rubber. A locking member for fixing the sliding position of the pad 231 relative to the pressing plate 23 is provided between the pad 231 and the pressing plate 23. The locking member is specifically a bolt.

[0048] It also includes a docking member 6, which is used to drive the pressure plate 23 and the pad 231 to slide in the direction close to the load-bearing platform 2 and press against the surface of the product to be tested when the load-bearing platform 2 moves to the surface of the lifting platform 54. Specifically, each load-bearing platform 2 is rotatably connected to a rotating rod 25, and the rotating rod 25 is arranged in a one-to-one correspondence with the pressure plate 23. A pull rope 24 is wound around the rotating rod 25, and one end of the pull rope 24 away from the rotating rod 25 is connected to the side wall of the pressure plate 23. The docking member 6 includes a docking gear 61 and a docking plate 62. The docking gear 61 is arranged in a one-to-one correspondence with the rotating rod 25 and is fixedly sleeved on the corresponding rotating rod 25. The docking plate 62 is arranged on the upper surface of the lifting platform 54, and a first tooth groove for meshing with the docking gear 61 is opened on the docking plate 62; when the load-bearing platform 2 slides to the top of the lifting platform 54 driven by the sliding component 33, and the lifting component 32 does not drive the load-bearing platform 2 to move downward, at this time, the first tooth groove position on the docking plate 62 The docking gear 61 on the bearing plate 2 moves downward along with the bearing plate 2. When the lifting component 32 drives the driving plate 31 downward, the bearing plate 2 will move downward along with the driving plate 31 under the action of its own weight, so that the docking gear 61 meshes with the first tooth groove and drives the rotating rod 25 to rotate, winding the pull rope 24, so that the pressure plate 23 drives the pad 231 to press against the product to be tested under the pull of the pull rope 24, so that the buffer layer 232 contacts the surface of the product to be tested. It should be noted that the weight of the bearing plate 2 is much greater than the resistance when the docking gear 61 meshes with the first tooth groove, so as to ensure that when the bearing plate 2 moves downward under the action of its own weight, the docking gear 61 can mesh with the first tooth groove and rotate.

[0049] Reference Figure 3 and Figure 5 , the frame 1 is also provided with a receiving station 112, which is located on the first track 11, and a receiving frame 14 with an upper opening is provided near the receiving station 112 of the frame 1, and the receiving frame 14 is located between the first track 11 and the second track 12. The frame 1 is also slidably connected with a push plate 13, and the cross section of the push plate 13 in the height direction is Z-shaped, and the sliding direction of the push plate 13 is perpendicular to the length direction of the first track 11 and the second track 12; when the return spring 22 is not deformed, that is, when the pressure plate 23 is not pressed against the surface of the product, the gap between the pressure plate 23 and the bearing table 2 can be passed through by the push plate 13, so that the push plate 13 pushes the product on the bearing table 2 away from the bearing table 2. The frame 1 is provided with a push piece 15 for driving the push plate 13 to slide, and the push piece 15 is specifically a cylinder, and the driving end of the push piece 15 is connected to the end of the push plate 13. The push plate 13 is used to push the tested product on the supporting table 2 on the receiving station 112 into the receiving frame 14 during the sliding process, and then push the supporting table 2 on the receiving station 112 to move from the receiving station 112 to the end of the second track 12.

[0050] Reference Figure 1 and Figure 7 , the frame 1 is also equipped with a visual inspection module 71 near the inspection station 111. The visual inspection module 71 can be specifically a camera for capturing the image of the product under test at the inspection station 111. The visual inspection module 71 is electrically connected to the control module 7. The control module 7 can be specifically a PLC controller, and the drive motor 52 is electrically connected to the controller. The control module 7 is used to control the forward and reverse rotation and opening and closing of the drive motor 52, so as to regularly release the pressure of the pressing member 5 on the product under test on the inspection station 111, so as to facilitate the visual inspection module 71 to clearly capture the image of the product under test on the inspection station 111. The control module 7 is also used to display the image through a pre-connected display screen so that the inspection personnel can know the inspection results. The paper tape transmission member 4 and the drive member 3 are both controlled by the control module 7, so as to control the start and stop of the paper tape transmission member 4 and the drive member 3 through the control module 7 to improve the degree of inspection automation.

[0051] The implementation principle of a coating product quality inspection device according to an embodiment of the present application is as follows: a supporting platform 2 loaded with the product to be inspected is placed at one end of the first track 11 away from the material receiving station 112, and two clamping blocks on the driving plate 31 located below the supporting platform 2 and closest to the supporting platform 2 are located on both sides of the supporting platform 2. Then, the driving member 3 drives the driving plate 31 to move upward so that the bearing platform 2 is inserted into the space between the two clamping blocks 311, and the bearing platform 2 continues to move up to a certain height under the lifting of the driving plate 31, and then slides a specified distance in the direction close to the detection station 111 and moves to above the lifting platform 54, and then the lifting component 32 drives the driving plate 31 to move downward, so that the bearing platform 2 moves down to the lifting platform 54 under the action of its own weight. During this process, the docking gear 61 on the bearing platform 2 will mesh with the first tooth groove and rotate. When the bearing platform 2 contacts the upper surface of the lifting platform 54, the pad 231 just presses against the surface of the product; the driving plate 31 will descend to a position where the clamping block 311 is located below the first track 11, and then the driving plate 31 is driven by the sliding component 33 to move in the opposite direction (that is, slide in the direction away from the detection station 111) a specified distance to achieve reset.

[0052] After the carrying platform 2 moves to the lifting platform 54, the lifting platform 54 and the carrying platform 2 are driven to move up to a predetermined height by the driving motor 52. At the same time, the pressing rod 53 moves toward the direction close to the carrying platform 2, and the product to be tested on the lifting platform 54 and the carrying platform 2 after rising to a predetermined height is just located on the rotation path of the pressing rod 53, so that the pressing rod 53 can rotate and press the paper tape against the surface of the product to be tested, and then the paper tape transmission component 4 is started to transmit the paper tape, so that the paper tape moves relative to the product to be tested, thereby realizing the friction of the paper tape against the surface of the product to be tested. The control module 7 can control the driving motor 52 to flip after a specified friction time, so that the pressing rod 53 is separated from the surface of the product to be tested, and the visual inspection module 71 is controlled to obtain an image of the surface of the product to be tested, so as to realize real-time judgment of the degree of friction.

[0053] After the inspection is completed, the carrying table 2 on the lifting platform 54 is transported to the receiving station 112 by the driving member 3 again, and the pushing plate 13 is driven by the pushing member 15 to push the tested product on the receiving station 112 into the receiving frame 14, and as the pushing plate 13 continues to slide, the pushing plate 13 will contact the carrying table 2 on the receiving station 112 and push it to the end of the second track 12, and it is assumed that the carrying table 2 moved to the end of the second track 12 is just located between the two adjacent clamping blocks 311 on the driving plate 31 under the second track 12, and because the sliding direction of the driving plate 31 under the second track 12 is opposite to that of the first track 11, the carrying table 2 will move to the end of the second track 12 away from the receiving station 112 under the successive transport of the driving plate 31 on the second track 12, so as to wait for the inspector to take it and load it with the subsequent tested products and then place it on the end of the first track 11 away from the receiving station 112, so as to realize the recycling of the carrying table 2.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
