DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the mirror roller surface defect detection device includes a detection platform 10 and a mirror roller body 60. A flipping mechanism 20, an auxiliary support mechanism 30 and a detection mechanism 50 are installed on the top of the detection platform 10. The flipping mechanism 20 and the auxiliary support mechanism 30 are symmetrically arranged, and a clamping mechanism 40 for fixing the mirror roller body 60 is installed on the side close to each other. The flipping mechanism 20 includes a flipping assembly 21 and a transmission assembly 22.

[0030] It should be noted that the mirror roller body 60 is fixed between two clamping mechanisms 40, and the mirror roller body 60 is driven to rotate by the flipping mechanism 20. At the same time, the detection mechanism 50 will move linearly on one side of the mirror roller body 60, scan and photograph the surface of the mirror roller body 60, and upload the photographed pictures to the PC, which can automatically identify whether there are defects on its surface.

[0031] like Figure 2 and Figure 3 As shown, the flip assembly 21 includes a driving unit and a support platform 213, the inner wall of the support platform 213 is fixedly connected with a cylinder 218, the output end of the cylinder 218 is fixedly connected with a bearing 214, the bearing 214 is connected to the clamping mechanism 40 through a rotating shaft 215, and the rotating shaft 215 is connected to the driving unit through a pulley 216 to control the rotation of the mirror roller body 60.

[0032] It should be noted that, through the cooperation of the transmission assembly 22, the pulley 2 216 can still maintain transmission with the driving part and the transmission assembly 22 during the lifting and moving of the rotating shaft 1 215.

[0033] like Figure 2 and Figure 3 As shown, the transmission assembly 22 includes a guide rod 221 fixed in the inner wall of the support platform 213, the outer ring of the guide rod 221 is movably sleeved with a guide block 222, the inner ring of the guide block 222 is rotatably sleeved with a rotating shaft 224, and an elastic member is arranged between the guide block 222 and the inner wall of the support platform 213, the two ends of the rotating shaft 224 are respectively fixedly connected with a pulley 3 225 and a plug plate 226, the pulley 3 225 is transmission-connected to the pulley 2 216 through a belt 217, the plug plate 226 is transmission-connected to the detection mechanism 50, after the clamping mechanism 40 falls to the detection area, the detection mechanism 50 is driven to move horizontally for detection, and after the clamping mechanism 40 moves up to the installation area of ​​the mirror roller body 60, it is disengaged from the detection mechanism 50.

[0034] Specifically, the oil cylinder 218 can drive the rotating shaft 215 to move up and down through the bearing 214. When the rotating shaft 215 rises, the belt 217 will be tightened, while the position of the driving part remains unchanged, and the guide block 222 will move toward the center position close to the support platform 213. When the rotating shaft 215 falls, the elastic member will pull the rotating shaft 224 to move away from the center position of the support platform 213, so that the driving part can always drive the rotating shaft 1 215 and the rotating shaft 2 224 to rotate. When the clamping mechanism 40 rises to the installation area of ​​the mirror roller body 60, the detection mechanism 50 stops moving for detection. At this time, it is convenient to remove or install the mirror roller body 60 from the two clamping mechanisms 40. During the disassembly and installation process, it will not collide with the detection mechanism 50, leaving sufficient operating space for it, which is convenient and quick.

[0035] like Figure 2 As shown, the driving unit includes a motor 211 fixed on the top of the detection platform 10, and the output end of the motor 211 is fixedly connected to a pulley 1 212, and the pulley 1 212 is transmission-connected to the pulley 2 216 and the pulley 3 225 through a belt 217.

[0036] Specifically, the motor 211 drives the pulley 1 212 to rotate, and the pulley 1 212 can simultaneously drive the pulley 2 216 and the pulley 3 225 to rotate through the belt 217, so that the rotating shaft 1 215 and the rotating shaft 2 224 can rotate synchronously.

[0037] like Figure 2 As shown, the elastic member includes a tension spring 223, which is sleeved on the outer ring of the guide rod 221, and has two ends fixedly connected to the inner wall of the support platform 213 and the side wall of the guide block 222 respectively.

[0038] Specifically, the force of the tension spring 223 will always pull the guide block 222 to move toward the side wall of the support platform 213, ensuring that the belt 217 remains taut to avoid slipping and transmission failure.

[0039] like Figure 4 As shown, the auxiliary support mechanism 30 includes a support platform 2 31 fixed on the top of the detection platform 10, and the inner wall of the support platform 2 31 is fixedly connected to a cylinder 2 34, and the output end of the cylinder 2 34 is connected to a rotating shaft 33 through a bearing 2 32, and the ends of the rotating shaft 33 and the rotating shaft 1 215 that are close to each other are both connected to the clamping mechanism 40.

[0040] Specifically, the oil cylinder 2 34 and the oil cylinder 1 218 have the same specifications and move synchronously in the same direction, so that the mirror roller body 60 fixed between the two clamping mechanisms 40 can maintain horizontal lifting.

[0041] like Figure 3 , Figure 4 and Figure 5As shown, the clamping mechanism 40 includes a chuck 41, and a plurality of oil cylinders 42 are installed in a circular array on the chuck 41. The output end of each oil cylinder 42 is fixedly connected to a flexible clamp block 43, and the two chucks 41 are respectively fixedly connected to one end of the rotating shaft 33 and the rotating shaft 1 215 that are close to each other.

[0042] Specifically, a plurality of oil cylinders 42 are arranged in an array with the center of the chuck 41 as the base point, and the axis of the mirror roller body 60 is fixed on the center of the chuck 41 through the flexible clamp block 43 connected thereto, so that the chuck 41 and the mirror roller body 60 rotate concentrically.

[0043] like Figure 6 As shown, the detection mechanism 50 includes a bearing frame 51 fixed on the top of the detection platform 10, and the bearing frame 51 is equipped with a screw rod 52. One end of the screw rod 52 is fixedly connected to a socket 53, and the socket 53 is plugged into the plug plate 226. The screw rod 52 is equipped with a defect detection part through a thread sleeve 54.

[0044] Specifically, when the rotating shaft 224 moves toward the center position of the support platform 1 213, the plug plate 226 will be disengaged from the socket 53, and the screw rod 52 will be unable to rotate to drive the defect detection part to move; when the rotating shaft 224 moves toward the center position away from the support platform 1 213, the plug plate 226 will be plugged into the socket 53, and the rotation of the screw rod 52 will drive the defect detection part to move, thereby detecting the mirror roller body 60.

[0045] like Figure 6 As shown, the defect detection unit includes a collection camera 58, which is fixedly connected to the thread sleeve 54 through a connecting seat 57. The bearing frame 51 is fixedly connected with a slide rod 55. The side of the connecting seat 57 away from the thread sleeve 54 is fixedly connected with a slide sleeve 56, and the slide sleeve 56 is movably mounted on the outer ring of the slide rod 55.

[0046] Specifically, through the cooperation between the slide rod 55 and the slide sleeve 56 , when the screw rod 52 rotates, the collection camera 58 does not rotate together, but moves linearly to capture and detect the surface of the mirror roller body 60 .

[0047] like Figure 3 , Figure 4 and Figure 5 As shown, both the rotating shaft three 33 and the rotating shaft one 215 are installed with a supporting mechanism 70; the supporting mechanism 70 includes a bearing four 71, the outer side of the bearing four 71 is fixedly connected with a connecting ear 72, the inner ring of the connecting ear 72 is movably sleeved with a supporting rod 73, the tail end of the supporting rod 73 is fixed to the top of the detection platform 10, and the two bearing fours 71 are respectively sleeved on the outer rings of the rotating shaft three 33 and the rotating shaft one 215.

[0048] It should be noted that the bearing four 71, the connecting ear 72 and the support rod 73 can not only provide support points for the rotating shaft three 33 and the rotating shaft one 215, but also facilitate the lifting and moving of the rotating shaft three 33 and the rotating shaft one 215.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
