[0029] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0030] However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of this disclosure. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of embodiments of this disclosure for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this disclosure.

[0031] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The term "comprising" as used herein indicates the presence of features, steps, or operations, but does not exclude the presence or addition of one or more other features.

[0032] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0033] Figure 1 This is a flowchart of a post-grinding control method applicable to a square bar integrated grinding machine according to an exemplary embodiment of the present disclosure.

[0034] According to one aspect of the inventive concept of this disclosure, a post-grinding control method suitable for a square bar integrated grinding machine is provided, such as... Figure 1 As shown, it includes operations S1 to S3.

[0035] According to some embodiments of this disclosure, operation S1 includes: acquiring post-grinding inspection data of the square bar. The post-grinding inspection data includes dimensional data of the head and tail of the square bar.

[0036] According to some embodiments of this disclosure, operation S2 includes: summing the head size data and the tail size data, and comparing the sum with the standard size of the square bar to obtain a first comparison result.

[0037] According to some embodiments of this disclosure, operation S3 includes: controlling the grinding disc power head to grind and correct the square bar based on the first comparison result.

[0038] In this embodiment, sensors automatically acquire the post-grinding detection values ​​of the upper, middle, lower, head, and tail of the square bar after grinding. The data is analyzed and processed to obtain the corresponding control harness for the grinding disc power head, which improves the utilization rate of centralized control time and the efficiency of inspection anomaly handling.

[0039] Figure 2 The head and tail dimension data of multiple midpoints are obtained by a post-grinding control method for a square bar integrated grinding machine according to an exemplary embodiment of the present disclosure.

[0040] According to some embodiments of this disclosure, such as Figure 2 As shown, the post-grinding inspection data includes the head and tail dimensions of multiple midpoints of the square bar.

[0041] According to some embodiments of this disclosure, controlling the grinding head to perform grinding correction on the square bar based on the comparison results includes adjusting the grinding correction time of the power head based on the comparison results and the grinding speed of the coarse grinding disc and the grinding speed of the fine grinding disc.

[0042] In this embodiment, the size of the single crystal after processing is determined by calculating the sum of the head and tail data. When the post-grinding inspection model detects a large post-grinding measurement value, the values ​​of the front and rear rough / fine grinding power heads are increased. Figure 2 As shown, if the specification of the square bar is 295, then the rated length of the side is 210.20±0.1mm. Taking the value of the midpoint 4 as an example, the calculated side length is 210.221, which is above the rated length of the side. Therefore, the front roughing / fine grinding power head needs to be increased by 2s at the same time, and the rear roughing / fine grinding power head needs to be increased by 2s at the same time.

[0043] According to some embodiments of this disclosure, the coarse grinding disc and the fine grinding disc comprise two sets, one in front and one behind, each set comprising two grinding discs arranged opposite to each other.

[0044] Figure 3The upper, middle, and lower images are obtained by the post-grinding control method for a square bar integrated grinding machine according to an exemplary embodiment of the present disclosure.

[0045] According to some embodiments of this disclosure, such as Figure 3 As shown, the post-grinding test data also includes the difference in dimensions of the upper, middle, and lower points of at least two surfaces. The difference is compared with a preset threshold to obtain a second comparison result. Based on the second comparison result, the grinding disc power head is controlled to grind and correct the square bar.

[0046] According to some embodiments of this disclosure, after obtaining the first comparison result and / or the second comparison result, the comparison result and the adjustment parameters of the grinding wheel power head are output.

[0047] According to some embodiments of this disclosure, the post-grinding test data includes data from four sides, wherein the difference between the data from the first side and the data from the second side is calculated, and the difference between the data from the third side and the data from the fourth side is calculated.

[0048] In this embodiment, the post-grinding inspection status of the single crystal is determined by detecting the differences between the middle and lower points on the four surfaces of the single crystal post-grinding inspection. Optionally, the difference at each point must not exceed 0.1. Further optionally, when the post-grinding inspection patrol model detects a post-grinding inspection difference greater than 0.1 during the inspection process, it displays the machine with abnormal data, quickly calculates the optimal adjustment scheme for the post-grinding inspection, displays the optimal reference scheme, and allows users to click "one-click modification" to complete the adjustment of the post-grinding inspection.

[0049] According to some embodiments of this disclosure, controlling the grinding wheel power head to perform grinding correction on the square bar based on the second comparison result includes selecting 1 / 4 of the maximum value of the difference as the adjustment amount to calculate the grinding correction time of the power head.

[0050] According to some embodiments of this disclosure, the integrated grinding equipment uses a flat-push process for grinding.

[0051] According to some embodiments of this disclosure, the post-grinding control method can simultaneously control multiple integrated grinding machines.

[0052] According to some embodiments of this disclosure, dimensional anomalies and post-grinding inspection data anomalies are measured by measuring sensors. As the equipment ages, the sensors may become less sensitive, leading to data deviations. Therefore, the post-grinding inspection patrol model only adds intelligent prompting functions, not intelligent decision-making functions, to avoid single-crystal anomalies caused by inaccurate measurements and incorrect decisions.

[0053] Figure 4 This is a flowchart and principle block diagram of a post-grinding control method applicable to a square bar integrated grinding machine according to exemplary embodiments of the present disclosure.

[0054] According to some embodiments of this disclosure, such as Figure 4 As shown, the process and principle of this embodiment include steps S100 to S700.

[0057] According to some embodiments of this disclosure, step S300 includes: determining whether the data of the four surfaces of the single crystal are abnormal; if the data are normal, proceed to the next step; if the data are abnormal, proceed to the first sub-branch steps S301 to S304.

[0058] According to some embodiments of this disclosure, the sub-branch step S301 includes: determining the magnitude of the plane data value, and adjusting the power head parameters (increasing / decreasing) accordingly based on the magnitude.

[0059] According to some embodiments of this disclosure, the sub-branch step S302 includes: if the planar data is large, increase the power head parameter value; if the planar data is small, decrease the power head parameter value; and output the result.

[0060] According to some embodiments of this disclosure, sub-branch step S303 includes: designing a size adjustment scheme based on the output result of sub-branch step S302.

[0062] According to some embodiments of this disclosure, step S400 includes: calculating the difference in surface data after grinding.

[0063] According to some embodiments of this disclosure, step S500 includes: comparing the data differences on the four faces of the single crystal (top, middle, bottom, head, and tail) with a preset threshold. If the comparison result is less than or equal to 0.1, proceed to the next step; if the comparison result is greater than 0.1, proceed to the second sub-branch steps S501 to S504.

[0064] According to some embodiments of this disclosure, the sub-branch step S501 includes: if the post-grinding error value exceeds the standard range, the power head parameters need to be adjusted until the post-grinding error value is adjusted to less than 0.1.

[0065] According to some embodiments of this disclosure, the sub-branch step S502 includes: adjusting the values ​​of points 1 and 3 requires changing the values ​​of the front coarsening and front finening power heads; adjusting the values ​​of points 2 and 4 requires changing the values ​​of the rear coarsening and rear finening power heads; if the current coarsening and front finening power heads increase by X, then the corresponding rear coarsening and rear finening power heads decrease by X, and the result is output.

[0066] According to some embodiments of this disclosure, sub-branch step S503 includes: designing an adjustment scheme for abnormal post-grinding detection data based on the output result of sub-branch step S502.

[0067] According to some embodiments of this disclosure, the sub-branch step S504 includes: completing the post-grinding abnormality inspection and adjustment, and returning to step S400.

[0068] According to some embodiments of this disclosure, step S600 includes: the difference between the post-grinding dimensional data and the planar detection data both meet the processing conditions.

[0069] According to some embodiments of this disclosure, step S700 includes: post-mold detection completed, then shut down.

[0070] According to another aspect of the inventive concept of this disclosure, a post-grinding control device suitable for a square bar integrated grinding machine is provided, comprising: a data acquisition module, a data processing module, a comparator, and a calculation module.

[0071] According to some embodiments of this disclosure, the data acquisition module is suitable for acquiring post-grinding inspection data of a square bar, which includes dimensional data of the head and tail of the square bar.

[0072] According to some embodiments of this disclosure, the data processing module is adapted to sum the head size data and the tail size data.
