Description

Technical Field

[0001] The invention relates to the technical field of ceramic workpiece grinding, and more specifically to a ceramic workpiece grinding control system and process based on visual measurement. Background Art

[0002] Ceramic workpieces refer to mechanical parts made of special ceramic materials through mixing, molding, sintering and processing. The materials of ceramic workpieces can be oxide ceramics, nitride ceramics, boride ceramics, carbide ceramics, etc. As an inorganic non-metallic material, ceramic workpieces have many properties that metal materials do not have, such as high strength, high hardness, high elastic modulus, and oxidation resistance. When processing ceramic workpieces, they need to be ground into standard sizes;

[0003] Ceramic grinding refers to the surface processing of ceramics with abrasives after forming or sintering. Ceramic grinding is divided into fixed abrasive processing and free abrasive processing. Ceramic grinding can improve the flatness of the workpiece, reduce surface roughness, increase the wear resistance of the workpiece, and improve the corrosion resistance of the workpiece. In addition, grinding can also be used to process various ceramic workpieces with special and complex forming surfaces.

[0004] Nowadays, when grinding ceramic workpieces, multiple ceramic workpieces are fixed on a jig as a whole and ground. However, different ceramic workpieces have different sizes, so they are fixed on the jig with different top heights. During grinding, the vertical feed rate of the tool is reduced. If the same grinding method is used, when the ceramic workpiece with a lower height cannot be ground, a low feed rate method will be used. At this time, the processing time is longer. For ceramic workpieces with a higher height, the feed rate when descending is used to facilitate the contact of the ceramic workpieces, which will cause damage to the tool and the ceramic workpiece.

[0012] In a preferred embodiment, the grinding unit receives the tool lifting value T, grinding value M and feed rate JG calculated by the analysis unit, and the grinding unit uses the tool lifting value T as the maximum tool lifting height of the tool after grinding. When the grinding value M received by the grinding unit is zero or a negative number, the grinding unit does not perform grinding processing on the ceramic workpiece.

[0027] Figure 2 It is a schematic diagram of the grinding process flow of the present invention. DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The ceramic workpiece grinding control system and process based on visual measurement involved in the present invention are not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Reference Figure 1 The present invention provides a ceramic workpiece grinding control system based on visual measurement, including a collection unit, a height unit, an analysis unit, a grinding unit, an adjustment unit and a control unit; the collection unit is used to collect image data information of the ceramic workpiece and data information of the ceramic workpiece itself, the height unit calculates the height value Z of the ceramic workpiece during grinding, the analysis unit calculates the feed amount JG during grinding, the grinding unit performs grinding according to the calculated tool lift value T, grinding value M and feed amount JG, the adjustment unit calculates the adjustment value T, and the control unit calculates the new feed amount XJ according to the adjustment value T;

[0030] The acquisition unit uses two cameras to acquire image data information of the ceramic workpiece in the fixture before processing, and the acquisition unit sends the acquired two image data information to the height unit, the height unit receives the two image data information sent by the acquisition unit and performs binocular height detection, and the height unit calculates the height value Z of the top of each ceramic workpiece relative to the top of the fixture. The calculation formula of the height value Z is: , where is the focal length of the camera, B is the distance between the parallel optical axes of the two cameras, and x1-x2 is the difference in coordinates of the projection of the inspected ceramic workpiece on the two image planes.

[0031] In an embodiment of the present application, when performing grinding processing on a ceramic workpiece, the height of the ceramic workpiece in the fixture is first detected. When the present application adopts binocular height detection to perform height detection, the binocular detection can utilize the image information provided by two viewpoints to eliminate the influence of factors such as lighting and size, thereby achieving more accurate distance measurement. Therefore, the height of the ceramic workpiece detected by the present application is more accurate. In subsequent ceramic grinding, for ceramic workpieces of different heights, the tool descent and the feed amount during grinding can be controlled according to their heights, thereby improving the overall processing efficiency.

[0032] Furthermore, when the height unit adopts binocular height calculation to calculate the height value Z, the height unit uses the center point of the top of the ceramic workpiece and the endpoint of the top of the fixture as feature points. When the ceramic workpiece is ground in each process step, all units work. When the height unit adopts binocular height calculation, template matching is required before generating the height value Z. When the height unit adopts binocular height calculation, template matching is required before generating the height value Z. The height unit adopts a sequential similarity detection algorithm for template matching. The sequential similarity detection algorithm calculates the similarity Ds, and the height unit adopts the template with the highest similarity Ds as the matching template. The calculation formula of similarity Ds is: , where m and n are the pixel sizes of the template, is the grayscale value range of the image captured by the first camera, It is the grayscale value range of the image captured by the second camera.

[0033] In the embodiment of the present application, when performing binocular height calculation, the present application uses the center point of the top of the ceramic workpiece and the endpoint of the top of the fixture as feature points. The center point of the top of the ceramic workpiece can represent the height of the ceramic workpiece, and the size of the fixture itself is relatively fixed, so its endpoint is a feature point, which can represent the height of the fixture itself, and then the template with the highest similarity Ds is used as the matching template, thereby improving the accuracy of the overall binocular height calculation, and all units are working during each process step of the grinding of the ceramic workpiece, because the ceramic workpiece needs to undergo rough grinding and multiple fine grindings to complete the grinding work, and each rough grinding and fine grinding has fixed size requirements. Therefore, before each grinding, the present application performs detection and calculation to ensure that the final grinding result is accurate enough.

[0034] Further, the height unit sends the calculated height value Z to the analysis unit, the analysis unit receives the height value Z and matches all the ceramic workpieces with their height values, and the analysis unit doubles the maximum height value Z to generate a value as the tool lift value T, the tool lift value T is based on the top of the fixture, and the analysis unit calculates the grinding value M, the calculation formula of the grinding value M is: , where BZ is the distance between the top of the ceramic workpiece after theoretical grinding and the top of the fixture. The analysis unit receives the data information of the ceramic workpiece and calculates the feed amount JG during grinding. The calculation formula of the feed amount JG is: , where k1 and k2 are weights, and 0≤k1≤1, 0≤k2≤1, k1+k2=1, MJ is the area of ​​the top of the ceramic workpiece, YD is the hardness of the top of the ceramic workpiece, and the calculated feed rate JG is the height of the grinding tool descending per second during grinding.

[0035] In an embodiment of the present application, the height value is matched with the ceramic workpiece. At this time, the height of all ceramic workpieces can be understood, and the value generated by doubling the maximum height value Z is used as the tool lift value T. The tool lift value T is the height to which the tool rises after grinding, and moves to the next ceramic workpiece at this height. The present application uses the value generated by doubling the maximum height value Z as the tool lift value T, which can not only avoid contact between the tool and the ceramic workpiece, but also reduce the time wasted due to a long tool lift distance. The grinding value M is the height that the ceramic workpiece itself needs to be ground. This part of the tool will be ground, so it needs to move slowly. When grinding is not required, the tool can move quickly to improve overall work efficiency. Based on the understanding of the grinding value M, the feed amount JG is calculated. At this time, the height of the ceramic workpiece's descent per second during grinding can be calculated according to the situation of the ceramic workpiece itself, thereby improving the grinding quality and avoiding the problem of quality degradation caused by faster or slower feeding.

[0036] Furthermore, the grinding unit receives the tool lifting value T, grinding value M and feed rate JG calculated by the analysis unit, and the grinding unit uses the tool lifting value T as the maximum tool lifting height of the tool after grinding. When the grinding value M received by the grinding unit is zero or a negative number, the grinding unit does not perform grinding processing on the ceramic workpiece. When the grinding value M received by the grinding unit is a positive number, the grinding unit uses the grinding value M as its grinding processing process, and the grinding unit uses the feed rate JG as the feed value when performing grinding processing.

[0037] In the embodiment of the present application, when performing grinding processing, if the grinding value M is zero or a negative number, it means that the height of the ceramic workpiece at this time is lower than the height after grinding, so the ceramic workpiece is skipped to avoid wasting time. In addition, it should be noted that since the ceramic workpiece itself needs to be ground multiple times, during the rough grinding stage, there is a situation where the height before grinding is lower than the height after grinding.

[0038] Reference Figure 1 The adjustment unit includes a detection module and a processing module. The detection module collects displacement data information WY under the vibration of the fixture during grinding of the ceramic workpiece, and the detection module sends the collected displacement data information WY to the processing module. The processing module receives the displacement data information WY and calculates the adjustment value T. The calculation formula of the adjustment value T is: , where WD is the temperature of the ceramic workpiece during grinding, CS is the temperature data of the ceramic workpiece before processing, SY is the decibel value of the sound during grinding of the ceramic workpiece, and XZ is the data correction value, the specific value of which can be set by the management personnel. The processing module sends the calculated adjustment value T to the control unit, and the control unit receives the adjustment value T and compares it with the internal threshold value Y. When the adjustment value T≥threshold value Y, the control unit controls the grinding unit to stop working, and the grinding tool needs to be ground. When the adjustment value T<threshold value Y, the control unit multiplies the calculated feed amount JG by the inverse of the adjustment value T to form a new feed amount XJ, and the control unit controls the grinding unit to operate with the new feed amount XJ.

[0039] In the embodiment of the present application, when grinding is performed, the environment in which it is located is in a constantly changing state, and the grinding generates heat. When the heat is high, it will cause the ceramic workpiece to expand itself, thereby causing the grinding process to fail. Therefore, the present application comprehensively considers the temperature change value of the ceramic workpiece during grinding (that is, the difference between the temperature of the ceramic workpiece during grinding and the temperature data of the ceramic workpiece before processing), the sound generated by grinding, and the vibration data during grinding. The calculated adjustment value T can accurately reflect the situation of the grinding process. When the adjustment value T ≥ threshold value Y, the problem of the grinding process is relatively large. At this time Shut down the machine for maintenance in time to avoid direct damage to the ceramic workpiece and the cutting tool. When the adjustment value T is less than the threshold value Y, the control unit multiplies the calculated feed amount JG by the inverse of the adjustment value T to form a new feed amount XJ. This is because the larger the adjustment value T is, the greater the impact caused by the faster rotation speed of the tool during grinding. For example, when the rotation is faster, the temperature will rise again and the noise generated will be louder. At this time, it is necessary to reduce the speed in time. Therefore, the feed amount JG is multiplied by the inverse of the adjustment value T, and the calculated new feed amount XJ can be automatically adjusted to ensure smooth grinding.

[0040] Reference Figure 2 , the ceramic workpiece grinding process based on visual measurement includes the following steps:

[0041] Step S1, fixing the ceramic workpiece in the fixture by filling glue, so that the ceramic workpiece is stably connected to the fixture;

[0042] Step S2, performing rough grinding detection on the first upward surface of the ceramic workpiece, and calculating the tool lift value T, the grinding value M and the feed rate JG before performing rough grinding;

[0043] Step S3, after grinding is completed, the second side of the ceramic workpiece facing downward is turned upward, so that the first side is adsorbed by the suction cup and then the second side is inspected, and the tool lift value T, grinding value M and feed amount JG are calculated again before rough grinding;

[0044] Step S4, measuring the bending degree of the ceramic workpieces to sort the ceramic workpieces, placing the ceramic workpieces with different bending degrees on suction cups with corresponding bending arcs, and detecting, calculating and fine grinding the upward surfaces of the ceramic workpieces;

[0046] Step S6, repeating steps S3 to S5 until the grinding process of the ceramic workpiece is completed.

[0047] In the embodiment of the present application, when grinding ceramic workpieces, inspection will be carried out before each grinding. After the inspection, each grinding will be carried out according to the preset tool lift value T, grinding value M and feed amount JG to ensure the processing quality. In addition, when the ceramic workpiece is bent during grinding, the ceramic workpiece will be sorted according to the degree of bending.
