Description

Technical Field

[0001] This utility model relates to the field of testing, and in particular to a ceramic plate appearance testing device. Background Technology

[0002] The appearance inspection of ceramic plates is crucial in modern industrial production because its quality directly affects the product's aesthetics and functionality. With technological advancements, traditional manual inspection methods have become increasingly inadequate to meet the demands of high-efficiency, high-precision production, leading to the development of automated inspection technologies.

[0003] The types of defects typically detected in ceramic plates include: scratches on the inner wall, black spots, yellow spots, glaze damage, chipped edges, and missing clay, among others. Currently, the equipment used for detecting defects in ceramic plates has limited functionality. Furthermore, due to the unique shape of ceramic plates, the inspection of the front and back of the product differs slightly, making it impossible to detect all defects in a single machine. Therefore, different defects require switching equipment or inspection methods, involving manual handling, transfer, or flipping. This process is inefficient, and the probability of additional scratches caused by human error during inspection increases, further raising overall costs and affecting overall inspection efficiency. Therefore, it is necessary to design a ceramic plate appearance inspection device to solve these problems. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0026] Reference Figure 1 This embodiment of a ceramic disc appearance inspection device includes a material conveying module 1, a first visual inspection module 2, a second visual inspection module 3, a third visual inspection module 4, a fourth visual inspection module 5, multiple sorting robots, a recycling bin module 9, a loading assembly line 10, a unloading assembly line 11, a loading robot 12, and an unloading robot 13. Two material conveying modules 1 are arranged parallel to each other on the machine platform, namely a first material conveying module 101 and a second material conveying module 102. Each material conveying module 1 is divided into two sections: a front material conveying module and a rear material conveying module. A flipping component 14 is provided between the two material conveying modules 1 to flip the product. The first visual inspection module 2, the second visual inspection module 3, the third visual inspection module 4, and the fourth visual inspection module 5 are sequentially arranged on one side of the material conveying module 1 for detecting different defects in the product. Multiple sorting robots are arranged sequentially along one side of the material conveying module 1. A recycling bin module is located below each sorting robot to collect defective or substandard products. The loading line 10 and unloading line 11 are respectively located at both ends of the length of the material conveying module 1, connecting to it. (Refer to...) Figure 8The loading robot 12 and unloading robot 13 have the same structure, respectively set at both ends of the machine and located between the two material conveying modules 1. Both include a multi-axis robot 123 mounted on the machine, and multiple suction cups 124 for adsorbing and transferring products are set at the head of the multi-axis robot 123. The loading robot 12 transfers the ceramic discs 100 to be tested from the loading line 10 to the second material conveying module 102, transferring one ceramic disc 100 at a time. Ceramic discs 100 not transferred by the loading robot 12 are directly connected to the upper material conveying module 102. The first conveyor module 101, aligned with the same straight line as the material conveyor line 10, continues to transport ceramic discs 100 to be inspected. These discs are conveyed from the first conveyor module 101 to the second conveyor module 102, moving from the front section to the rear section. At the unloading end, the unloading robot 13 transfers the inspected ceramic discs 100 from the second conveyor module 102 to the unloading line 11. The qualified ceramic discs 100 inspected on the first conveyor module 101 are then directly conveyed out of the equipment along the same straight unloading line 11. The conveyor module 1 uses an existing segmented belt conveyor system for product transport.

[0027] Specifically, the first visual inspection module 2 and the second visual inspection module 3 are located in the pre-process of the flip assembly 14, while the third visual inspection module 4 and the fourth visual inspection module 5 are located in the post-process of the flip assembly 14. (Refer to...) Figure 2 The first visual inspection module 2 includes a first inspection camera 21 and a first inspection light source 22. The first inspection camera 21 and the first inspection light source 22 are mounted above the material conveying module 1 via a first bracket 23. The first inspection camera 21 is an area array camera, and the first inspection light source 22 is a strip light source. Four strip light sources are arranged in a circle below the first inspection camera 21. The first inspection camera 21 is used to detect scratches on the inner wall of the ceramic disc.

[0028] Reference Figure 3The second visual inspection module 3 includes a second inspection camera 31 and a second inspection light source 32, which are mounted above the material conveying module 1 via a second bracket 33. The third visual inspection module 4 includes a third inspection camera and a third inspection light source, which are also mounted above the material conveying module 1 via a third bracket. Both the second and third inspection light sources are bowl-shaped, similar in shape to an inverted bowl, providing uniform and wide illumination. The light emitted by the LEDs is reflected by the arched bowl shape to form diffused illumination, achieving uniform illumination of the curved ceramic plate surface and reducing shadows and reflections on the object surface. Both the second and third inspection cameras are area array cameras. The second visual inspection module 3 is used to detect defects such as black spots, yellow spots, glaze damage, and white edges on the front of the ceramic plate. The third visual inspection module 4 is used to detect defects such as chipped feet, glaze shrinkage at the base, missing clay, and glaze streaks on the back of the ceramic plate. The second visual inspection module 3 and the third visual inspection module 4 have the same structure, and the third visual inspection module 4 can also be referenced. Figure 3 .

[0029] Reference Figure 4 The fourth vision inspection module 5 includes a fourth inspection camera 51 and a fourth inspection light source 52. The fourth inspection camera 51 is mounted on the machine platform via a fourth support frame 53 and is located above the material conveying module 1. The fourth inspection light source 52 is a flat backlight and is located below the material conveying module 1 to provide illumination from below the ceramic disc 100. Four fourth inspection cameras 51 are arranged opposite each other at four positions above the material conveying module 1. This design eliminates the need for a rotating structure to drive product rotation, simplifying the equipment structure. Images from the four cameras can be stitched together to obtain the full view of the product at once, thus improving inspection efficiency. Furthermore, combined with... Figure 1 The fourth vision inspection module 5 also includes a light shield 54. An image capture port is opened at the position of the light shield 54 corresponding to the fourth inspection camera 51. The lens part of the fourth inspection camera 51 extends into the light shield 54 through the image capture port. When the ceramic disk 100 is transmitted to the area below the fourth inspection camera 51, it provides an environment that blocks other stray light for acquiring product images.

[0030] Furthermore, refer to Figure 5 The flipping assembly 14 includes a rotary motor 141, a rotary shaft 142, and clamping plates 143. Two pairs of clamping plates 143 are horizontally symmetrically arranged on the rotary shaft 142. The two pairs of clamping plates 143 connect to two material conveying modules 1 and are used to receive and hold the ceramic discs 100 transferred from the front material conveying module. The ceramic discs 100 are flipped by rotation, and the flipped ceramic discs 100 are placed on the rear material conveying module for continued conveying. The flipping assembly 14 is mounted on the machine base by a support frame 145.

[0031] Multiple sorting robots, including a first-sorting robot 6, a second-sorting robot 7, and a third-sorting robot 8, are arranged sequentially on one side of the material conveying module 1 along its conveying direction, for transferring and unloading different types of defective products. (Refer to...) Figure 6 Each specific robotic arm includes a Y-axis linear module 61, a Z-axis lifting module 62, and a suction cup assembly 63. The Y-axis linear module 61 is mounted on the machine platform via a column 64. The Z-axis lifting module 62 is mounted on the Y-axis linear module 61, and the suction cup assembly 63 is mounted on the Z-axis lifting module 62. The suction assembly 63 includes multiple suction cups. After the suction cups pick up the ceramic disc 100 on the material conveying module, they are driven by the Y-axis linear module 61 to move above the recycling bin module 9. Then, they are driven by the Z-axis lifting module 62 to descend and place the ceramic disc 100 into the recycling bin module 9. Finally, they rise and move to the material conveying module 1, repeating the loading and unloading process. Figure 6 Only one type of robotic arm is shown. The first type robotic arm 6, the second type robotic arm 7, and the third type robotic arm 8 have the same structure and can be referenced simultaneously. Figure 6 .

[0032] Reference Figure 7 The recycling bin module 9 includes a material frame 91 and a lifting drive mechanism 92. The material frame 91 is set on the machine platform, and the lifting drive mechanism 92 is set inside the machine platform and below the material frame 92. An opening 94 is provided at the bottom of the material frame 91. The lifting drive mechanism 92 includes a lead screw stepper motor with lead screw movement. A support plate is provided at the top of the lead screw 93. The support plate passes through the opening 94 under the drive of the lead screw 93 to support the ceramic disc 100 inside the material frame 91.

[0033] Below each of the first, second, and third sorting robotic arms (6, 7, and 8) is a recycling bin module (9). A lead screw stepper motor lifts a pallet to the top of the material frame (91). As the sorting robotic arms successively transfer ceramic discs (100) into the material frame (91), the lead screw stepper motor lowers the pallet until the material frame (91) is full of ceramic discs (100), at which point the workers can remove all the ceramic discs (100). This one-to-one correspondence between the sorting robotic arms and the recycling bin modules (9) enables rapid sorting and unloading of products with different defects, eliminating the need for subsequent sorting and picking.

[0034] Workflow: The ceramic discs 100 to be inspected are placed on the loading line 10 and sent to the conveying module 1. The loading robot 12 transfers a portion of the ceramic discs 100 from the loading line 10 to the second conveying module 102. The ceramic discs 100 are then diverted to the first conveying module 101 and the second conveying module 102 for conveying and inspection, greatly improving efficiency. At the front of the first conveying module 101 and the second conveying module 102, the front of the ceramic disc 100 sequentially passes through the first vision inspection module 2 and the second vision inspection module 3 for two different types of defect inspection. After being flipped by the flipping component 14, it continues to be conveyed to the subsequent conveying module, sequentially to the third vision inspection module 4 and the fourth vision inspection module 5 for defect inspection of the reverse side of the ceramic disc 100. On the first conveying module 101, the first sorting robot 6 and the second sorting robot... The first and third classification robots 7 and 8 respectively pick up ceramic discs 100 with different defects and put them into the recycling bin module 9 according to the inspection results. The qualified ceramic discs 100 without defects are directly transferred to the unloading assembly line 11. On the assembly line of the second material conveying module 102, the ceramic discs 100 with defects are picked up by the first classification robot 6, the second classification robot 7 and the third classification robot 8 respectively according to the type of defect and put into the recycling bin module 9. The qualified ceramic discs 100 are picked up by the unloading robot 13 and transferred to the unloading assembly line 11.

The understanding of this specification should be based on those skilled in the art. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present utility model. All technical solutions and improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
