Description

Technical Field

[0001] This utility model relates to the field of ceramic tile quality inspection technology, and in particular to a visual inspection device for finished ceramic tiles. Background Technology

[0002] In the tile production process, quality inspection is necessary, and visual inspection is an important means of detecting surface defects, dimensions, and other quality indicators. With the development of tile production technology, tile sizes are becoming increasingly diverse, leading to a growing demand for the inspection of large-size tiles.

[0003] In existing tile visual inspection devices, when encountering larger tiles, the camera, due to its fixed height, cannot capture a clear image of the entire tile surface, resulting in poor inspection results. Simultaneously, the auxiliary illumination light source cannot adjust accordingly to changes in camera height, preventing adequate coverage of large tiles and affecting the accuracy of detecting surface defects. Existing inspection devices struggle to meet the demands for efficient and accurate inspection of tiles of varying sizes, especially large tiles. Therefore, there is an urgent need for a visual inspection device that can flexibly adjust the camera height and light source illumination when tile size changes. Utility Model Content

[0029] Please see Figure 1-5 This utility model provides a visual inspection device for finished ceramic tiles, comprising:

[0030] Rack 1;

[0031] Gantry 2 is fixedly mounted on frame 1;

[0032] The lifting plate 3 is located below the upper side wall of the gantry frame 2, and a vision camera 31 is installed at the center of the lower side wall of the lifting plate 3.

[0033] A light-concentrating cover 4 is installed on both sides of the lifting plate 3, and a light source 41 is installed inside the light-concentrating cover 4.

[0034] Height adjustment mechanism 5 is mounted on gantry 2 and is used to adjust the height of vision camera 31.

[0035] Angle adjustment mechanism 6 is installed on the lifting plate 3 and is used to adjust the illumination angle of the light source lamp 41.

[0036] The above structure enables the testing of tiles of different sizes.

[0037] The height adjustment mechanism 5 includes an internal threaded sleeve 51, which is fixedly embedded in the center of the upper side wall of the gantry frame 2. An adjusting screw 52 is internally threaded to the internal threaded sleeve 51. A handwheel 53 is fixedly connected to the upper end of the adjusting screw 52, ​​and the lower end of the adjusting screw 52 is rotatably connected to the lifting plate 3.

[0038] With the above structure, the height of the vision camera 31 can be changed by adjusting the height of the lifting plate 3. When encountering a larger tile, the vision camera 31 can be raised to obtain a more comprehensive tile image.

[0039] The angle adjustment mechanism 6 includes two sets of fixed ears 61, with two fixed ears 61 in each set. The two fixed ears 61 are symmetrically arranged on the side wall of the lifting plate 3. A rotating rod 62 is rotatably provided between the two fixed ears 61. The light-concentrating cover 4 is fixedly connected to the rotating rod 62. One end of the rotating rod 62 passes through one of the fixed ears 61 and is fixedly connected to a gear 63. Two racks 64 are fixedly connected to the inner wall of one side of the gantry frame 2.

[0040] With the above structure, the light-concentrating cover 4 can be unfolded while adjusting the height of the vision camera 31, increasing the illumination area of ​​the light source and ensuring that the light source can evenly and comprehensively illuminate the tile surface at different vision camera 31 heights.

[0041] It also includes an image acquisition (not shown in the figure) and processing system (not shown in the figure). The image acquisition and processing system is connected to the vision camera 31 and is used to receive the tile images acquired by the vision camera 31 and process and analyze them to determine whether the tiles are qualified. The image acquisition and processing system includes an image acquisition card and image processing software. The image acquisition card is used to acquire the image signals output by the vision camera 31, and the image processing software is used to perform defect identification, size measurement and other processing on the acquired images. The image acquisition and processing system and the vision camera 31 are all mature existing technologies, so they will not be elaborated on here.

[0042] Guide rods 21 are slidably inserted on both sides of the upper side wall of the gantry frame 2. The lower end of the guide rods 21 is fixedly connected to the lifting plate 3. The guide rods 21 play a guiding and limiting role for the lifting plate 3, so that it can only move in a straight line and will not rotate.

[0043] Among them, gear 63 meshes with rack 64.

[0044] The frame 1 has a conveying mechanism 11, which is used to convey ceramic tiles. The conveying mechanism 11 is a mature existing technology, and its structure and principle will not be described in detail here.

[0045] It should be noted that this utility model is a visual inspection device for finished ceramic tiles. In use, the conveying mechanism 11 transports the tiles to a position below the visual camera 31. The visual camera 31 captures an image of the tile surface. The image signal is transmitted to an image acquisition card via a data cable. The image acquisition card transmits the acquired image signal to a computer. The image processing software in the computer performs defect identification, size measurement, and other processing and analysis on the image to determine whether the tile is qualified. When the area of ​​the inspected tile increases, the handwheel 53 is rotated, causing the adjusting screw 52 to rotate. When the adjusting screw 52 rotates, the surface of the tile is inspected. Under the action of the internal threaded sleeve 51, the adjusting screw 52 will drive the lifting plate 3 to move upward, thereby driving the vision camera 31 to move upward, so that the vision camera 31 can obtain a more comprehensive image of the tile. When the lifting plate 3 moves upward, it will drive the fixing ear 61, the rotating rod 62 and the condenser 4 to move upward. The gear 63 meshing with the rack 64 will drive the rotating rod 62 to rotate. The rotation of the rotating rod 62 will drive the condenser 4 to rotate, so that the condenser 4 will unfold and increase the illumination range of the light source 41 to adapt to the larger tile surface, thereby improving the accuracy and reliability of detecting defects and dimensions on the tile surface.
