Description

Technical Field

[0001] The present invention relates to the technical field of quartz ceramic roller production, and specifically refers to a micro-crack detection device for quartz ceramic rollers. Background Art

[0002] A quartz ceramic roller is a roller-shaped industrial component made of quartz as the main raw material through a specific process, with ceramic characteristics. It usually has characteristics such as high purity, high hardness, high temperature resistance, wear resistance, good thermal stability, and strong chemical stability. It can maintain good dimensional stability and mechanical properties in high-temperature environments and is widely used in industries such as solar photovoltaic, semiconductor, glass, and electronics.

[0003] During the production process of quartz ceramic rollers, micro-cracks may occur on the surface of the quartz ceramic rollers due to the influence of raw materials, production process factors, and the assembly process. These micro-cracks are very small, usually only a few micrometers or even smaller. Even some high-precision detection instruments require particularly stable conditions to accurately detect. Existing detection devices are difficult to fix the ceramic quartz roller stably. Excessive force during clamping is likely to break the ceramic roller, and it is also difficult to fully cover the detection surface, resulting in missed detection and false detection phenomena, which in turn affect the product performance and bring risks of equipment damage, causing economic losses to enterprises. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a micro-crack detection device for quartz ceramic rollers, which at least partially solves the problems raised in the above background art.

[0005] The technical solution adopted by the present invention is as follows: A micro-crack detection device for quartz ceramic rollers, comprising: Rotary fixing components, with two groups arranged oppositely. The rotary fixing components include hydraulic rods, movable blocks, connecting blocks, movable rings, driven sprockets, fixed rods, and clamping blocks; The movable blocks are fixedly arranged at the movable ends of the hydraulic rods, and the connecting blocks are symmetrically arranged at the upper and lower ends of the movable blocks; The inner walls of the movable rings are fixedly arranged on the connecting blocks, and the driven sprockets are rotatably arranged at one end of the movable rings away from the hydraulic rods; The fixed rods are fixedly arranged on the side walls of the driven sprockets, and the clamping blocks are arranged at the ends of the fixed rods; There are multiple groups of the fixed rods, and multiple groups of the fixed rods are arranged at equal intervals.

[0006] Further, the micro-crack detection device for quartz ceramic rollers further includes a detection table and detection equipment. The detection table is arranged below the rotary fixing components, and the detection equipment is arranged near the rear end of the detection table; The detection table includes a base, columns, and a support plate. The columns are relatively fixed at both ends of the base. The support plate is fixedly arranged on the inner side walls of the columns. The fixed end of the hydraulic rod is arranged on the support plate and abuts against the columns. The movable block is movably arranged on the support plate.

[0007] Among them, the movable block is circular, the support plate is arc-shaped, and the movable block fits against the inner wall of the support plate.

[0008] In a further embodiment, a wire hole is provided on the support plate, and one set of the connecting blocks movably penetrates through the wire hole.

[0009] Furthermore, a sliding groove is provided on the base. A sliding plate is slidably arranged on the sliding groove. One end of the sliding plate close to the column is fixedly provided with a connecting rod. The upper end of the connecting rod is fixedly arranged on the lower wall of the movable ring. The sliding plate is arranged below the driven sprocket.

[0010] Furthermore, a rotating motor is fixedly arranged on the sliding plate. The output shaft end of the rotating motor is fixedly provided with a driving sprocket. A transmission chain is movably arranged on the driving sprocket and the driven sprocket.

[0011] In a further embodiment, multiple groups of patterns are provided on the contact surface of the clamping block to increase the surface friction of the clamping block and drive the body of the quartz ceramic roller to rotate.

[0014] The beneficial effects achieved by the present invention with the above structure are as follows: Through the linkage of the hydraulic rod driving the movable block, the driven sprocket and the clamping block, the quartz ceramic roller is fixed by abutting from both ends. The operator only needs to perform a simple operation of controlling the hydraulic rod to quickly complete the fixing step, which is convenient to operate and improves the preparation efficiency before detection. Rotating the driven sprocket drives the quartz ceramic roller to rotate slowly, enabling it to pass through the detection window in all directions, ensuring that micro-cracks, flatness, etc. on the roller surface can be accurately captured by the detection equipment, effectively avoiding missed detections and misdetections, and improving the accuracy of detection. Utilizing the cooperation of the driving sprocket, the driven sprocket and the transmission chain, the power of the rotating motor is stably transmitted, realizing the uniform rotation of the clamping block driving the quartz ceramic roller, which not only ensures the smooth progress of the detection process, but also makes the entire device operate reliably, reduces the downtime for maintenance due to mechanical failures, and improves the overall work efficiency. The roller rods at both ends of the quartz ceramic roller to be detected can be placed on the support plate to start the subsequent operations, which can adapt to quartz ceramic rollers of different specifications and sizes and meet the diversified production detection requirements.

[0020] During the production process of the quartz ceramic roller, micro-cracks may occur on the surface of the quartz ceramic roller due to raw materials, production process factors, and the assembly process. These micro-cracks are very small, usually only a few micrometers or even smaller. Even some high-precision detection instruments require particularly stable conditions to accurately detect them.

[0021] Existing detection devices are difficult to stably fix the ceramic quartz roller. Excessive force during clamping is likely to break the ceramic roller, and it is also difficult to fully cover the detection surface, resulting in missed detections and false detections, which in turn affect the product performance and bring risks of equipment damage, causing economic losses to the enterprise.

[0022] After recognizing the above problems, the present application proposes and discloses a micro-crack detection device for a quartz ceramic roller, which can stably fix the ceramic quartz roller, fully cover the detection surface, and avoid missed detections and false detections.

[0023] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the present disclosure provides a micro-crack detection device 10 for a quartz ceramic roller, including: There are two sets of rotation and fixing components 1 provided oppositely. The rotation and fixing component 1 includes a hydraulic rod 2, a movable block 3, a connecting block 4, a movable ring 5, a driven sprocket 6, a fixing rod 7, and a clamping block 8; The movable block 3 is fixedly arranged at the movable end of the hydraulic rod 2. The connecting blocks 4 are symmetrically arranged at the upper and lower ends of the movable block 3. The inner wall of the movable ring 5 is fixedly arranged on the connecting block 4.

The clamping block 8 is arranged at the end of the fixing rod 7; There are multiple groups of fixing rods 7, and multiple groups of fixing rods 7 are arranged at equal intervals.

[0024] In this embodiment, the quartz ceramic roller to be tested is placed between two sets of rotating fixed components 1, and the movable end of the hydraulic rod 2 drives the movable block 3 to approach the quartz ceramic roller. The movable block 3 drives the clamping block 8 from both ends to press against the roller body of the quartz ceramic roller to fix it through the driven sprocket 6 and the fixed rod 7.

[0025] The clamping block 8 is driven to rotate by rotating the driven sprocket 6, and the clamping block 8 drives the quartz ceramic roller to slowly rotate through the detection window 21, so that the detection equipment can perform all-round detection on the quartz ceramic roller.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the quartz ceramic roller micro-crack detection device 10 also includes a detection table 9 and a detection device 10, the detection table 9 is arranged below the rotating fixed component 1, and the detection device 10 is arranged near the rear end of the detection table 9; The testing platform 9 includes a base 11, a column 12 and a support plate 13.

[0027] In this embodiment, the roller rods at both ends of the quartz ceramic roller to be inspected are placed on the support plate 13, and then the roller body of the quartz ceramic roller is fixed by the clamping block 8 of the rotating fixing component 1. When the driven sprocket 6 is rotated, the clamping block 8 drives the roller body of the quartz ceramic roller to slowly rotate through the detection port of the detection equipment 10 for comprehensive inspection to prevent missed detection and false detection.

[0028] In this embodiment, the detection device 10 is a machine vision detection device, which can quickly scan and detect a large area of ​​the surface of the quartz ceramic roller and detect fine cracks.

[0037] As Figure 3 shown, multiple groups of textures are provided on the contact surface of the clamping block 8 for increasing the surface friction of the clamping block 8 and driving the body of the quartz ceramic roller to rotate.

[0038] In this embodiment, the clamping block 8 is made of rubber material.

[0039] Rubber material itself has a relatively high friction coefficient and anti-slip characteristics, which helps to improve the stability of clamping the body of the quartz ceramic roller, ensure a stable rotation speed of the quartz ceramic roller during rotation, improve the detection accuracy of the detection device 10, and avoid missed detection and false detection phenomena due to speed changes.
