Description

Technical Field

[0001] The present invention mainly relates to the technical field related to ceramic sleeve defect detection, and specifically relates to a fluorescent agent coating device and method for ceramic sleeve end face defect detection. Background Art

[0002] Ceramic bushings, with their physical and mechanical properties such as high hardness, high wear resistance, corrosion resistance, and high temperature resistance, have been widely used in various cutting-edge fields. However, the processing steps for ceramic bushings are complex, and each step may result in defects that affect performance, such as cracks, pores, and inclusions. These defects are tiny in size and pose a serious threat to the strength and lifespan of ceramic bushings. Therefore, it is necessary to use highly sensitive testing methods to comprehensively detect micro-defects in ceramic bushings. Fluorescent penetrant testing technology utilizes the principle of liquid capillary action. A penetrant containing a fluorescent dye is applied to the surface of the ceramic material, and the penetrant penetrates into open surface defects. After cleaning to remove excess penetrant, the fluorescent dye emits visible light under ultraviolet light, thereby indicating the location, shape, and size of the defect. Fluorescent penetrant testing can detect surface defects such as pores and cracks with openings as small as 1μm.

[0003] Defect inspection on both end faces of ceramic bushings involves penetrating the defect with fluorescent agent, then rinsing with clean water. The fluorescent agent-penetrated material is then inspected under a fluorescent lamp. Currently, when applying fluorescent agent, the entire product is immersed in the original fluorescent agent solution, then removed and rinsed. This requires five rinses, increasing the consumption of fluorescent agent raw materials and the amount of fluorescent agent wastewater. This increases environmental pollution and subsequent treatment costs, making it difficult to mass-produce and inspect ceramic bushings. Summary of the Invention

[0037] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0038] This embodiment provides a fluorescent agent coating device for detecting defects on the end face of a ceramic bushing. In this embodiment, the device is described in detail by taking a ceramic bushing with a size of Φ3.2mm*Φ2.49mm*11.4mm to be coated as an example.

[0039] The main components of this equipment are as follows.

[0040] The tooling structure for loading materials.

[0041] The tooling for loading mainly includes three parts: a loading tooling 1, a charging tooling 4 and a cover plate, wherein there are two cover plates, namely a first cover plate 2 and a second cover plate 3.

[0042] For the loading tooling 1, it uses acrylic rubber material to make a 100mm*100mm*9mm square as the main body, and processes 100 evenly distributed Φ3.8mm receiving holes on it. The receiving holes pass through the loading tooling 1 along the thickness direction, and 45-degree chamfers are processed on the two end faces of the receiving holes to facilitate the entry of the ceramic sleeve.

[0043] The first cover plate 2 and the second cover plate 3 have the same structure. They are both made of 100mm*100mm*3mm acrylic blocks, and are machined with Φ1mm through holes. The through holes correspond to the centers of the Φ3.8mm receiving holes. The through holes on the cover plates can discharge some dust during use.

[0044] When used with the loading fixture 1, the first and second cover plates 2 and 3 are attached to the surface of the loading fixture 1, sealing the receiving hole. Both the first and second cover plates 2 and 3 are attached to the loading fixture 1 using magnetic attraction to facilitate assembly and disassembly of the cover plates. Specifically, a Φ6*2 magnet disc is installed at each of the four corners of the upper and lower surfaces of the loading fixture 1, and at each of the four corners of at least one surface of the first and second cover plates 2 and 3. These discs are designated as the fixture magnet 5, the first cover plate magnet 6, and the second cover plate magnet 7, respectively.

[0045] The loading fixture 4 is primarily used to assist with loading, specifically, to assist in inserting multiple ceramic sleeves into the receiving holes of the loading fixture 1. The loading fixture 4 utilizes a 120mm*120mm*20mm acrylic plate as its main body. 3.6mm loading holes are machined to correspond to the centers of the 3.8mm holes uniformly distributed on the loading fixture 1. The top end of the loading fixture 4 is machined into a 10mm deep hollow funnel shape with an inverted eight, and a 101mm*101mm*3mm stepped groove is machined at the bottom to accommodate the loading fixture 1.

[0046] The specific usage of the above-mentioned loading tooling structure is as follows: take out the first cover plate 2 and make it magnetically adsorbed to the lower end surface of the loading tooling 1 for cooperation, and install the loading tooling 1 into the step groove at the lower end of the loading tooling 4. After completion, take some ceramic sleeves and place them in the hopper on the upper part of the loading tooling 2 and shake them. The ceramic sleeves fall one by one through the loading hole to the receiving hole below. When the receiving hole is full, the material placement is completed.

[0047] Fluorescent coating structure.

[0048] In the fluorescent agent coating structure, the fluorescent agent is mainly dipped into the industrial sponge head and then coated on the two end faces of the ceramic sleeve. Its structural composition is mainly as follows.

[0049] The positioning platform 26 is the main platform for supporting the ceramic sleeve, with dimensions of 500*400*10mm. Its upper surface is provided with a tooling positioning slot 24 and a cover plate positioning slot 25. During use, the loading tool 1 with material is placed in the tooling positioning slot 24, and the first cover plate 2 or the second cover plate 3 is placed in the cover plate positioning slot 25. The bottom of the positioning platform 26 is connected to the platform lifting assembly, which mainly includes a platform lifting drive motor 28 and a platform drive screw 27. That is, the motor and screw drive the positioning platform 26 to achieve height adjustment.

[0050] An electrical control cabinet 12 is located on one side of the positioning platform 26. The control system is located below the electrical control cabinet 12. A platform is located above the electrical control cabinet 12, on which a 200mm*200mm*200mm stainless steel fluorescent agent container box 11 is located for holding the fluorescent agent concentrate. A bracket is located above the fluorescent agent container box 11, on which a dipping head translation assembly 10 is mounted. A lifting cylinder 9 is located below the dipping head translation assembly 10, and an industrial sponge dipping head 8 is mounted on the main shaft of the lifting cylinder 9. The dipping head translation assembly 10 drives the industrial sponge dipping head 8 to switch workstations, and the lifting cylinder 9 drives the industrial sponge dipping head 8 to rise and fall, thereby achieving the dipping and coating of the fluorescent agent.

[0051] In a preferred solution provided in this embodiment, the material hardness of the industrial sponge dipping head 8 is 40-50 degrees Shore hardness. If it is too hard, it cannot effectively cover the position of the product end surface. If it is too soft, it will cause the loss of fluorescent agent and cause environmental pollution.

[0052] The turning structure of the material.

[0053] In this embodiment, the above structure allows the industrial sponge dipping head 8 to dip the fluorescent agent and then apply it to the upper end surface of the ceramic sleeve. Because this device needs to complete the fluorescent agent coating on both ends of the ceramic sleeve, a structure for flipping the ceramic sleeve is also designed. The structure is as follows:

[0054] A multi-degree-of-freedom robotic arm 12 is mounted on the positioning platform 26. A cover plate gripper 23 is mounted on the robotic arm 12 to grip the cover plate. Specifically, when the material is flipped, the upper portion must first be placed against the upper cover plate to prevent the ceramic sleeve from falling. After flipping, the upper cover plate must be removed to facilitate the application of fluorescent agent. This process is accomplished by the robotic arm 12 driving the cover plate gripper 23.

[0055] A tool clamping assembly 14 is provided on one side of the positioning platform 26 for clamping and fixing the loading tool 1 during flipping. The tool clamping assembly 14 can be flipped 180 degrees by the tool flipping assembly, lifted and lowered by the tool lifting assembly, and translated by the tool translation assembly. Specifically, the tooling clamping assembly 14 clamps the loading tooling 1 through two tooling clamping cylinders 13. The tooling lifting assembly includes a base plate seat 21, a tooling lifting screw guide rail assembly 18, and a tooling lifting drive motor 20. The lifting and lowering control is achieved through the motor and screw guide rail structure. The tooling translation assembly is installed on the tooling lifting screw guide rail assembly 18. The tooling translation assembly includes a U-shaped guide rail screw assembly 17 and a tooling translation drive motor 19. The translation motion is also controlled by the motor guide rail screw structure. The tooling flipping assembly is installed on the U-shaped guide rail screw assembly 17. The tooling flipping assembly includes a flipping drive motor 15 and a tooling flipping assembly 16. The flipping action is achieved through the motor gear set structure. The tooling clamping assembly 14 is installed on the output shaft of the tooling flipping assembly 16.

[0056] In this embodiment, the above-described structure enables the lifting, translation, and flipping of the tooling clamping assembly 14, thereby conveniently controlling its movement to the loading tooling 1 and performing flipping operations. It should be understood that the structures in the drawings of this application are merely schematic, and that the platform lifting drive motor 28, platform drive screw 27, U-shaped guide rail screw assembly 17, tooling lifting screw guide rail assembly 18, and tooling flip assembly 16 can all be implemented using existing technologies, so the detailed structures are not shown.

[0057] The specific process of implementing phosphor coating on the end face of a ceramic sleeve by the above-mentioned device of this embodiment is as follows:

[0058] Combine the loading tooling 1 and the first cover plate 2, combine the charging tooling 4 and the loading tooling 1, and then place the ceramic sleeve into the hopper of the charging tooling 4 and shake it manually. The ceramic sleeve will freely enter the receiving hole of the loading tooling 1, and then take out the charging tooling 4. After completion, clean up the excess material.

[0059] Place the loading tool 1 filled with materials into the tool positioning slot 24, place the second cover plate 3 into the cover plate positioning slot 25, fill the fluorescent agent container 11 with fluorescent agent liquid in advance, check the operation of the equipment, and see if everything has returned to the origin and there is no abnormality. Then click the one-button start button and the equipment will run automatically.

[0060] The industrial sponge dipping head 8 first moves slowly downward and moves into the fluorescent agent container box 11 to dip the fluorescent agent. After completion, it will slowly rise and be controlled by the dipping head translation assembly 10 to move forward to the position of the loading tooling 1, and move downward to the height of the ceramic sleeve to smear and cover the end face of the product. After completion, the industrial sponge dipping head 8 rises and returns to the original point.

[0061] The multi-degree-of-freedom robotic arm 22 grabs the second cover plate 3 through the cover plate clamp 23, moves it to the position of the loading fixture 1, and then assembles it to the upper surface of the loading fixture 1. After completion, the robotic arm 22 returns to the origin.

[0062] The tooling clamping assembly 14 moves to the position of the loading tooling 1 to clamp it, and the positioning platform 26 is driven by the motor to slowly move downward. After reaching the designated position, the positioning platform 26 stops, and the tooling flip assembly 16 rotates the clamped loading tooling 1 180 degrees and stops after completion. The positioning platform 26 then slowly rises and fits the bottom of the loading tooling 1;

[0063] The robot arm 22 moves again to grab the first cover plate 2 on the upper surface of the loading tool 1, remove it, place it in the cover plate positioning groove 25, and then return to the origin.

[0064] The tool clamping assembly 14 releases the loading tool 1 and slowly returns to the original point, and starts the industrial sponge dipping head 8 again to apply fluorescent agent to the other end face (current upper end face) of the ceramic sleeve.

[0065] The equipment stops running, the coated loading tool 1 is taken out, the whole process is finished, and the subsequent operations repeat the above actions.
