DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Embodiment 1:

[0020] like Figure 1-2 As shown, Figure 1 This is a schematic diagram of the overall structure of a plate roller detector according to the first embodiment of the utility model. Figure 2 It is a structural schematic diagram of the plate roller installation device of the first embodiment of the utility model.

[0021] The utility model provides a plate roller detector: including a fixed seat 101, a support shaft 102, a mounting block 103 and an industrial camera 104, and also including a plate roller mounting device, the plate roller mounting device includes a rotating disk 106, a rotating shaft 107, a fixed cylinder 108, a second gear 109, a rotating assembly and a limiting assembly, the rotating assembly includes a ring gear 110 and a driving component, the driving component includes a third gear 111 and a reduction motor 112, and the above-mentioned scheme solves the problem that the above-mentioned device drives the middle plate roller to rotate through the support shafts on both sides and the rubber-coated rollers on the support shafts, so as to detect the plate roller, but the number of plate rollers detected by this driving method is limited, which reduces the detection efficiency of the plate roller. It can be understood that this scheme can also be used to solve the problem of limiting the plate roller.

[0022] In this embodiment, by driving the six groups of plate rollers to rotate and circulate, the industrial camera 104 can simultaneously photograph the surfaces of the six groups of plate rollers, thereby improving the detection efficiency of the plate rollers.

[0023] The rotating disk 106 is rotatably mounted on the support shaft 102 through the rotating assembly and is close to the mounting block 103. The rotating shaft 107 is rotatably mounted on the rotating disk 106. The second gear 109 is fixedly mounted on the rotating shaft 107 and meshes with the first gear 105. The fixed cylinder 108 is fixedly mounted on the rotating shaft 107 and is located at one end of the rotating shaft 107 away from the rotating disk 106. The limiting assembly is mounted on the supporting shaft 102. The industrial camera 104 is electrically connected to an image acquisition card (not shown in the figure), and the image acquisition card is electrically connected to an external visual processor. The model of the industrial camera 104 is MARS-5000-24GTC-TF. The rotating disk 106 is a disc-shaped structure. The number of the rotating shaft 107 and the fixed cylinder 108 are both six groups. And are distributed in an annular manner on the rotating disk 106, each group of the rotating shafts 107 is connected to a group of the second gears 109, and the fixed cylinder 108 coincides with the axis of the rotating shaft 107. When the plate rollers are installed, the rotating disk 106 is driven to rotate around the axis of the support shaft 102 through the rotating assembly, and the rotation of the rotating disk 106 drives the six groups of plate rollers to rotate circumferentially through the rotating shaft 107 and the fixed cylinder 108. At the same time, the second gear 109 on the rotating shaft 107 drives the rotating shaft 107 to rotate by itself through the engagement with the first gear 105. Under the drive of the rotating shaft 107, the plate rollers on the fixed cylinder 108 rotate by themselves, thereby driving the six groups of plate rollers to rotate and circulate, so that the industrial camera 104 can simultaneously shoot the surfaces of the six groups of plate rollers, thereby improving the detection efficiency of the plate rollers.

[0024] Secondly, the ring gear 110 is sleeved on the rotating disk 106 and fixedly connected to the rotating disk 106; the driving component drives the ring gear 110 to rotate, and the outer ring of the ring gear 110 is provided with teeth. The ring gear 110 is welded to the outer side of the rotating disk 106. The driving component drives the ring gear 110 to rotate, so that the ring gear 110 drives the rotating disk 106 to rotate, thereby achieving the rotation effect of the rotating disk 106.

[0025] Again, the reduction motor 112 is fixedly mounted on the fixed base 101; the third gear 111 is fixedly mounted on the output shaft of the reduction motor 112 and meshes with the ring gear 110. The reduction motor 112 is fixed to the fixed base 101 close to the rotating disk 106 by bolts. The third gear 111 is a spur gear. The reduction motor 112 drives the third gear 111 to rotate. The third gear 111 drives the ring gear 110 to rotate by meshing with the ring gear 110, thereby achieving a rotation effect on the ring gear 110.

[0026] In this embodiment, when in use, the ends of the six groups of plate rollers are respectively inserted into the six groups of fixed cylinders 108, and then the six groups of plate rollers are limited on the fixed cylinder 108 by the limiting assembly. Then, the reduction motor 112 is started to rotate, and the reduction motor 112 drives the third gear 111 to rotate. The third gear 111 drives the gear ring 110 to rotate by meshing with the gear ring 110. The gear ring 110 drives the rotating disk 106 to rotate around the axis of the support shaft 102 by being fixedly connected with the rotating disk 106. The rotation of the rotating disk 106 drives the fixed cylinder 108 and the plate rollers on the fixed cylinder 108 to rotate circumferentially around the axis of the support shaft 102 through the rotating shaft 107. When the second gear 109 on the rotating shaft 107 rotates in the circumferential direction, it will rotate around its own axis through the engagement with the first gear 105, and drive the fixed cylinder 108 and the plate roller to rotate by themselves through the fixed connection with the rotating shaft 107. At this time, the industrial camera 104 located on the mounting block 103 will shoot the surface of the six groups of plate rollers, and the photographed images are collected by the image acquisition card. When the visual processor receives the collected image signal, it will perform various operations to extract the target features, and then judge the quality of the plate roller. By driving the six groups of plate rollers to rotate and circulate, the industrial camera 104 can simultaneously shoot the surfaces of the six groups of plate rollers, thereby improving the detection efficiency of the plate rollers.

[0030] Among them, the movable disk 201 is installed on the support shaft 102 through the movable component, and is located at the end of the support shaft 102 away from the rotating disk 106; the rotating cylinder 202 is rotatably installed on the movable disk 201, the axis of the movable disk 201 coincides with the axis of the support table and the rotating disk 106, the rotating cylinder 202 is rotatably matched with the movable disk 201 through a bearing, the opening direction of the rotating cylinder 202 is toward the fixed cylinder 108, the number of the rotating cylinders 202 is six, and the position of the rotating cylinder 202 corresponds to the fixed cylinder 108 one by one, when one end of the plate roller is inserted into the fixed cylinder 108, the movable component drives the movable disk 201 to move toward the rotating disk 106, so that the rotating cylinder 202 is pressed and contacted with the other end of the plate roller, thereby realizing the limitation of the plate roller.

[0031] Secondly, the electric push rod 203 is fixedly mounted on the fixed seat 101; the pushing seat 204 is fixedly mounted on the output end of the electric push rod 203 and is rotatably connected to the movable disk 201.

The upper surface of the pushing seat 204 is provided with an arc-shaped groove for rotating with the movable disk 201, and is adapted to the arc surface of the movable disk 201. The electric push rod 203 pushes the movable seat through its output end, so that the movable seat pushes the movable disk 201 to move. At the same time, when the plate roller rotates, the movable disk 201 can rotate around the axis of the support shaft 102 and on the pushing seat 204, thereby realizing the driving of the movable disk 201.

[0032] In this embodiment, the electric push rod 203 pushes the moving seat through its output end, so that the moving seat pushes the moving disk 201 to move toward the rotating disk 106, so that the rotating cylinder 202 is pressed and contacted with the other end of the plate roller, thereby achieving the limitation of the plate roller.
