Description

Technical Field

[0001] This utility model relates to the field of ceramic testing technology, specifically to a testing structure for ceramic blanks. Background Technology

[0002] In the industrial production of ceramics, the fired body often develops micron- to millimeter-sized cracks on its surface and inside due to factors such as uneven distribution of thermal stress, differences in cooling rates, or fluctuations in raw material ratios. In particular, such defects result in a high product scrap rate, significantly impacting production efficiency and economic benefits. Traditional quality inspection relies primarily on manual visual inspection, with workers judging the location and severity of cracks based on experience.

[0003] This method has obvious limitations: First, the human eye is not good at identifying small microcracks, resulting in a high rate of missed detections; second, prolonged repetitive work can easily cause visual fatigue, leading to subjective fluctuations in inspection standards and a high rate of missed detections; third, manual inspection is affected by the difference in the experience level of operators, making it difficult to unify the defect judgment standards, and the same batch of products may be misjudged due to changes in inspectors; fourth, manual inspection is inefficient and cannot match the production efficiency of modern automated production lines.

[0004] Therefore, there is an urgent need to provide an automated detection structure for ceramic blanks to solve the above-mentioned technical problems. Summary of the Invention

[0005] In response to the problems in related technologies, this utility model proposes a detection structure for ceramic blanks, which can achieve efficient and accurate defect detection of ceramic blanks through an automated detection device.

[0006] This utility model is implemented as follows:

[0007] A detection structure for a ceramic blank includes an operating table, a motion module, and an execution module; the upper side of the operating table is used to place the ceramic blank; the motion module is disposed on one side of the operating table, and the execution module is disposed on the motion module; specifically, the execution module can be hinged to the motion module, or the execution module can be fixedly disposed at the free end / execution end of the motion module;

[0008] The execution module includes a coloring unit and a camera device;

[0009] The motion module is used to adjust the position and orientation angle of the execution module in three-dimensional space;

[0010] The coloring unit is used to operate on the exposed surface of the ceramic body and form a color layer;

[0011] The camera device is used to capture images of any defects or flaws present on the exposed surface.

[0012] Specifically, the color-developing layer formed by the color developer can make defects such as cracks on the surface of the ceramic body more visually apparent, thereby improving the recognition accuracy of the imaging device. The color developer can be kerosene or other auxiliary color-developing liquids.

[0013] Specifically, the exposed surface refers to the surface other than the bottom. Generally, the surface refers to the outer surface; for structures with an inner surface, it also includes the inner surface.

[0014] Camera devices, such as webcams.

[0015] This solution automates the inspection process of ceramic blanks through motion and execution modules, enabling high-precision and high-accuracy continuous operation. It avoids defects such as human inspection errors, inconsistent evaluation standards, and missed detections caused by visual fatigue, and achieves standardized operation.

[0016] As a further optimization of the above solution, the motion module is a robotic arm; the robotic arm includes at least two drive units, giving the robotic arm at least two degrees of freedom; the end of the robotic arm is provided with the drive unit, and is connected to the execution module through the drive unit.

[0017] The number of drive units can be adjusted according to the complexity of the exposed surface of the ceramic blank to provide more degrees of freedom.

[0018] As a further optimization of the above solution, the motion module is a multi-dimensional movement axis device; the multi-dimensional movement axis device includes at least three movement axes, namely the x-axis, y-axis and z-axis, to adjust the position of the execution module in three-dimensional space.

[0020] As a further optimization of the above solution, the coloring unit is a nozzle; the nozzle stores a color developer.

[0021] Alternatively, the execution module may further include a storage unit, which is connected to the nozzle and is used to store the color developer;

[0022] The nozzle sprays the color developer onto the exposed surface to form the color layer.

[0023] In other solutions, a "nozzle" can also be called a "spray gun," which refers to a structure that can spray liquid under pressure.

[0024] As a further optimization of the above solution, the coloring unit is a coating structure, which is impregnated with a color developer; the coating structure performs a coating operation on the exposed surface to form the color developing layer.

[0025] The application materials include brushes, paintbrushes, rollers, and sponges.

[0026] As a further optimization of the above solution, the execution module is also provided with a detachable or fixed expansion unit; the expansion unit is a defect marking unit or a defect repair unit.

[0027] The defect marking unit is used to physically mark the defects; after marking, the defects are located according to the marking in the next process, which can be manual or automated.

[0028] The defect repair unit is used to eliminate the defects. When a crack is found, it is directly eliminated.

[0029] As a further optimization of the above solution, the defect marking unit is a smearing structure, which is impregnated with liquid pigment; the smearing structure performs a smearing operation on the exposed surface to form a mark.

[0030] The liquid pigment is food red (or carmine) or other pigments.

[0031] As a further optimization of the above solution, the defect marking unit is a nozzle; the nozzle stores liquid pigment.

[0032] Alternatively, the execution module may further include a storage unit, which is connected to the nozzle and is used to store liquid pigments;

[0033] The nozzle sprays the liquid pigment onto the exposed surface to form a mark.

[0034] As a further optimization of the above solution, the defect repair unit is a scraper.

[0035] Furthermore, the scraper includes a blade holder and a blade; the blade holder includes a Y-shaped structure; the blade is connected between the two ends of the forked blade holder.

[0036] As a further optimization of the above solution, the operating table includes a support mechanism for carrying the ceramic blank, the ceramic blank being disposed on the support mechanism; the support mechanism is selected from at least one structural form among a fixed worktable, a rotary worktable, or a linear conveying device. The linear conveying device includes a roller conveyor line, a chain conveyor line, or a belt conveyor line.

[0037] Adjusting the side orientation of the ceramic blank using a rotating worktable can reduce the difficulty of operating the robotic arm.

[0038] The beneficial effects are as follows:

[0039] This invention provides a detection structure for ceramic blanks. Through motion and execution modules, it automates the ceramic blank detection process, enabling high-precision, high-accuracy, and sustainable operation. It avoids defects such as missed detections caused by manual inspection errors, inconsistent evaluation standards, and visual fatigue, achieving standardized operation. This effectively reduces defect detection costs and better matches the production efficiency of modern automated production lines and downstream processes. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] Example 1

[0053] like Figure 1 , 2 As shown, this embodiment provides a detection structure for a ceramic blank, including an operating table 1, a motion module 2, and an execution module 3.

[0054] In this embodiment, the ceramic body 4 is the body structure of a toilet.

[0055] The upper side of the operating table 1 is used to place the ceramic blank 4; the motion module 2 is located on one side of the operating table 1, and the motion module 2 is hinged to the execution module 3. Specifically, in this embodiment, the motion module 2 is a robotic arm; the robotic arm includes 5 drive units 21 (i.e., motors), and the end of the robotic arm is connected to the execution module 3 through the drive units 21. The motion module 2 is used to adjust the position and orientation angle of the execution module 3 in three-dimensional space. Specifically, the movement of the robotic arm can be planned through its built-in teaching mode, combined with manual fine-tuning.

[0056] The execution module 3 includes a coloring unit 31 and a camera device 32; in this embodiment, the execution module 3 is also provided with a detachable extension unit; the extension unit is a defect marking unit 33.

[0058] Specifically, in this embodiment, the camera device 32 is a camera used to capture images of defects and flaws on the exposed surface, particularly minute gaps. Specifically, the exposed surface refers to the surface other than the bottom, including both the inner and outer surfaces.

[0059] In this embodiment, the defect marking unit 33 is used for physically marking defects. Specifically, the defect marking unit 33 is a nozzle; the nozzle stores liquid pigment; the nozzle sprays the liquid pigment onto the exposed surface to form a mark. The liquid pigment is food red (or carmine). After marking, the defect is located according to the mark in the next process, which can be manual or automated.

[0060] In this embodiment, the execution module 3 is also equipped with a lidar 35. The lidar 35 serves as an obstacle avoidance device, preventing the motion module 2, such as the robotic arm, from interfering with or being disturbed by other structures when operating the execution module 3.

By adjusting the side orientation of the ceramic blank 4 through the rotary worktable 11, the operation difficulty of the robotic arm can be reduced.

[0066] In this embodiment, the defect marking unit 33 is a smearing structure, specifically a brush. The smearing structure is impregnated with liquid pigment; the liquid pigment is food red (or carmine). The smearing structure performs a smearing operation on the exposed surface, applying it to the cracks / fissures to form a mark.

[0067] Specifically, the end of the blemish marking unit 33 (brush) extends beyond the end of the coloring unit 31 (nozzle).

[0068] In this embodiment, the execution module 3 is also equipped with a lidar 35. The lidar 35 serves as an obstacle avoidance device, preventing the motion module 2, such as the robotic arm, from interfering with or being disturbed by other structures when operating the execution module 3.
