Description

Technical Field

[0001] The present invention relates to the technical field of surface sandblasting of watch bottom cases, and more particularly, to a method for surface sandblasting of wearable watch bottom cases. Background Art

[0002] As a portable timekeeping tool worn on the wrist, a wearable watch has a certain decorative function while achieving the timekeeping effect. In order to improve the appearance texture of the watch and increase wear resistance, the surface of the watch bottom case needs to be sandblasted, which can significantly change the surface texture of the watch, making it more high-end and grand, while increasing the sense of modernity and personalized elements.

[0003] During the process of sandblasting the surface of the watch bottom case by existing sandblasting equipment, since the sandblasting equipment can only perform sandblasting on the bottom case surface according to a predetermined sandblasting process set manually, its degree of autonomous intelligence is relatively low, and it is difficult to identify the specific conditions of the watch case to determine whether the sandblasting process is correct, resulting in the phenomenon of sandblasting errors. At the same time, it is difficult to prevent sandblasting abnormalities caused by the established process in a timely manner, which is likely to increase cost losses while affecting the sandblasting efficiency.

[0004] Therefore, we propose a method for surface sandblasting of wearable watch bottom cases. Summary of the Invention

[0005] The main object of the present invention is to provide a method for surface sandblasting of wearable watch bottom cases to overcome the problems mentioned in the above background art.

[0006] To achieve the above object, the present invention provides a method for surface sandblasting of wearable watch bottom cases, including the following steps:

[0007] Step 1: Collect high-definition images of the surface of the bottom case to be sandblasted, extract the characteristic factors of the surface of the bottom case to be sandblasted from the images, identify and determine the material type of the bottom case to be sandblasted based on the characteristic factors, divide several types of materials, set several sandblasting processes corresponding to the material types, screen and match the material type of the bottom case to be sandblasted with the several sandblasting processes, select the sandblasting process with the highest matching rate and mark it as sandblasting process No. 2, and set it as the first sandblasting reference process of the sandblasting equipment;

[0008] Step 2: Obtain the type of sandblasting effect required on the surface of the bottom case to be sandblasted, adjust the sandblasting parameters of sandblasting process No. 2 corresponding to the first sandblasting reference process based on the type of sandblasting effect, mark the sandblasting process No. 2 with the adjusted sandblasting parameters as sandblasting process No. 3, and set it as the second sandblasting reference process of the sandblasting equipment;

[0009] Step 3: Obtain the preset sandblasting process of the sandblasting equipment, sum up the sandblasting process No. 1 sandblasting parameters corresponding to the preset sandblasting process to obtain the preset sandblasting index, sum up the sandblasting process No. 3 sandblasting parameters corresponding to the sandblasting reference process 2 to obtain the sandblasting index, calculate the index difference between the preset sandblasting index and the sandblasting index, process and analyze the index difference to obtain the matching degree between the preset sandblasting process and the second reference process, and determine whether the current preset sandblasting process is accurate based on the matching degree. If the matching degree is high, it is determined that the preset sandblasting process is accurate and a sandblasting instruction is generated. If the matching degree is low, it is determined that the preset sandblasting process is inaccurate and a warning instruction is generated;

[0010] Step 4: Obtain the instruction. If the obtained instruction is a sandblasting instruction, control the sandblasting equipment to run according to the preset sandblasting process to perform sandblasting treatment on the watch case. If the obtained instruction is a warning instruction, control the sandblasting equipment to suspend operation and transmit the warning signal to the mobile terminal of the management personnel;

[0011] Step 5: Collect high-definition images of the surface of the sandblasted bottom case, compare them with the surface images of the qualified sandblasted bottom cases, find the difference points between the two images for processing to obtain the corresponding difference value, and process and analyze the difference value to obtain the qualified index of the sandblasted bottom case.

[0012] As a further improvement of the present invention, the specific analysis of Step 1 is as follows:

[0013] 101. Establish an integrated monitoring facility for high-definition image collection at the entrance of the sandblasting equipment, and use intelligent monitoring equipment to collect and intercept high-definition images of the surface of the bottom case;

[0014] 102. Extract the characteristic factors on the surface of the bottom case from the images, including identification characters, glossiness, and color, process the characteristic factors to obtain the characteristic index, set several types of materials and number them in sequence, process the characteristic factors corresponding to several types of materials to obtain the preset characteristic index, and match the characteristic index with the preset characteristic index. If the match is successful, mark the corresponding material number. If the match fails, mark it as a new material;

[0015] 103. Set the sandblasting processes corresponding to several types of materials. Based on the marked material number of the bottom case, match and obtain the corresponding sandblasting process and mark it as sandblasting process No. 2, set it as sandblasting reference process 1. If the currently marked material of the bottom case is a new material, execute it with sandblasting process No. 1 corresponding to the preset sandblasting process.

[0016] As a further improvement of the present invention, the specific process of processing the characteristic index is as follows: Obtain all characteristic factors and substitute them into the formula TZ = BS × β1 + GZ × β2 + YS × β3 to obtain the characteristic index TZ, where BS, GZ, and YS represent the identification character, glossiness, and color value respectively, and β1, β2, and β3 represent the set weight factors respectively;

[0017] Obtain the characteristic factors corresponding to several types of materials set, substitute them into the formula TZ' = BS' × β1 + GZ' × β2 + YS' × β3 to obtain the preset characteristic index TZ', where BS', GZ', and YS' represent the preset identification character, preset glossiness, and preset color value respectively. According to different material types, the preset identification character can be BS1', BS2,... The preset glossiness can be GZ1', GZ2,... The preset color can be YS1', YS2,... Based on different material types, preset characteristic indexes TZ1', TZ2,... can be obtained.

[0018] As a further improvement of the present invention, the specific analysis of step two is as follows:

[0019] 201. Obtain the type of sandblasting effect required on the surface of the sandblasted bottom shell, including uniform sandblasting, local sandblasting, and special sandblasting. Based on the selected type of sandblasting effect, adjust the sandblasting parameters of sandblasting process No. 2 corresponding to sandblasting reference process No. 1;

[0020] 202. Obtain the sandblasting parameters of sandblasting process No. 2, which are composed of the abrasive value and the sandblasting value together to form the sandblasting parameters of sandblasting process No. 2. Among them, the abrasive value is composed of the particle size, hardness, and shape value of the abrasive, and the sandblasting value is composed of the sandblasting pressure, sandblasting distance, sandblasting angle, and sandblasting time value;

[0021] 203. Use the abrasive value and the sandblasting value to form the sandblasting parameters of sandblasting process No. 2 corresponding to sandblasting reference process No. 1. Based on the selected type of sandblasting effect, obtain the sandblasting path set as the adjustment parameter. The parameters composed of the abrasive value, the sandblasting value, and the sandblasting path form sandblasting process No. 3, which is set as sandblasting reference process No. 2.

[0022] As a further improvement of the present invention, the specific process of processing the abrasive value and the sandblasting value is as follows: Obtain the abrasive value ML through the formula ML = KL × γ1 + YD × γ2 + XZ × γ3, where KL, YD, and XZ represent the particle size, hardness, and shape value of the abrasive respectively, and γ1, γ2, and γ3 represent the set weight factors respectively;

[0023] Obtain the sandblasting value PS through the formula PS = YL × δ1 + JL × δ2 + JD × δ3 + SJ × δ4, where YL, JL, JD, and SJ represent the sandblasting pressure, sandblasting distance, nozzle angle, and sandblasting time value respectively, and δ1, δ2, δ3, and δ4 represent the set weight factors respectively.

[0024] As a further improvement of the present invention, step three is specifically analyzed as follows:

[0025] 301. Obtain the first sandblasting parameters of the sandblasting process corresponding to the preset sandblasting process, including the preset abrasive value, preset sandblasting value, and preset sandblasting path parameters, and perform a summation calculation to obtain the preset sandblasting index;

[0026] The summation calculation of the preset sandblasting index is: obtain the preset sandblasting index PZ' through the formula PZ'=(ML'×ε1 + PS'×ε2)+(LJ'×ε3), where ML', PS', and LJ' respectively represent the preset abrasive value, preset sandblasting value, and preset sandblasting path parameters, and

[0027] ε1, ε2, and ε3 respectively represent the set proportional coefficient factors;

[0028] 302. Obtain the third sandblasting parameters of the sandblasting process corresponding to the sandblasting reference process two, including the abrasive value, sandblasting value, and sandblasting path parameters, and perform a summation calculation to obtain the sandblasting index;

[0029] The summation calculation of the sandblasting index is: obtain the sandblasting index PZ through the formula PZ=(ML×ε1 + PS×ε2)+(LJ×ε3), where ML, PS, and LJ respectively represent the abrasive value, sandblasting value, and sandblasting path parameters;

[0030] 303. Substitute the preset sandblasting index and the sandblasting index into the formula ZC = |PZ'×φ1 - PZ×φ2| to obtain the index difference ZC, where φ1 and φ2 represent the set proportional coefficient factors, set the index difference threshold ZC', and select the maximum value to the minimum value within its influence range to form the index difference threshold interval (-ZC', ZC', +ZC'). If ZC ∈ (-ZC', ZC', +ZC'), the degree of coincidence is high, and it is determined that the preset sandblasting process accurately generates a sandblasting instruction. If and > +ZC', the degree of coincidence is low, and it is determined that the preset sandblasting process does not accurately generate a warning instruction.

[0031] As a further improvement of the present invention, step four is specifically analyzed as follows:

[0032] 401. If the obtained instruction is a sandblasting instruction, then according to the first sandblasting process corresponding to the preset sandblasting process, select the abrasive particle size, hardness, and shape corresponding to the abrasive value, and set the spray gun structure of the sandblasting equipment according to the sandblasting pressure, sandblasting distance, sandblasting angle, and sandblasting time corresponding to the sandblasting value, and set the sandblasting path of the spray gun structure, and jointly control the sandblasting equipment to perform the sandblasting operation;

[0033] 402. If the obtained instruction is a warning instruction, control the sandblasting equipment to suspend operation, analyze the warning instruction to obtain warning nodes, generate warning signals based on the warning nodes and transmit them to the mobile terminal of the management personnel. The management personnel can quickly find the location of the warning problem according to the warning nodes and perform repairs.

[0034] As a further improvement of the present invention, analyzing the warning instruction to obtain warning nodes specifically includes: inputting the abrasive value and its composition factors into a computer to construct a two-dimensional coordinate graph. Taking the abrasive value as the horizontal axis of the two-dimensional coordinate system, taking the number of composition factors as each node on the horizontal axis of the two-dimensional coordinate system, taking the value of the composition factor as the vertical axis of the two-dimensional coordinate system, and connecting the marked coordinate points with a smooth curve to form an abrasive value curve graph;

[0035] Input the sandblasting value and its composition factors into a computer to construct a two-dimensional coordinate graph. Taking the sandblasting value as the horizontal axis of the two-dimensional coordinate system, taking the number of composition factors as each node on the horizontal axis of the two-dimensional coordinate system, taking the value of the composition factor as the vertical axis of the two-dimensional coordinate system, and connecting the marked coordinate points with a smooth curve to form a sandblasting value curve graph;

[0036] Input the sandblasting path into a computer to construct a two-dimensional plan view, set a two-dimensional plan view that matches the surface of the bottom shell, and control the sandblasting path to extend on the two-dimensional plan view according to the sandblasting effect type to obtain a sandblasting path simulation graph;

[0037] Repeat the above process by substituting the preset abrasive value, preset sandblasting value, and preset sandblasting path to obtain the corresponding preset abrasive value curve graph, preset sandblasting value curve graph, and preset sandblasting path simulation graph. Compare the corresponding graphs of each one, and the warning nodes of the preset sandblasting process and the second sandblasting reference process can be obtained according to the comparison error.

[0038] As a further improvement of the present invention, step five is specifically analyzed as follows:

[0039] 501. By establishing an integrated monitoring facility for high-definition image acquisition at the outlet of the sandblasting equipment, use an intelligent monitoring device to collect and intercept high-definition images of the surface of the bottom shell;

[0040] 502. Obtain the image of the surface of the bottom shell after sandblasting and set it as the real-time image, set the image of the surface of the qualified sandblasted bottom shell as the reference image, compare the real-time image with the reference image, find the differences between the real-time image and the reference image and mark them as difference points, and process the difference points to obtain a difference value;

[0041] 503. Set a difference threshold, and select the maximum value to the minimum value within its influence range to form a difference threshold interval. Match the difference value with the difference threshold interval. If the match is successful, it indicates that the difference value is small and the sandblasting qualification index is high, and mark the sandblasted bottom case as a qualified product. If the match fails, it indicates that the difference value is large and the sandblasting qualification index is low, and mark the sandblasted bottom case as a defective product.

[0042] As a further improvement of the present invention, the specific process for processing the difference value is as follows: Count the number of difference points. If the number of difference points is greater than zero, set several difference ranges, and each difference range corresponds to an influence coefficient. If a difference point is within a difference range, match the influence coefficient corresponding to that difference range. Match all the difference points with several difference ranges respectively to obtain the corresponding influence coefficients, and then sum up the values corresponding to all the influence coefficients to obtain the total influence value. Input the values of the number of difference points and the total influence value into a computer. Use the value of the total influence value as the bottom circle radius and the value of the number of difference points as the height to establish a cylinder, select the volume of the cylinder and mark the volume value as the difference value.

[0043] The beneficial effects of the present invention:

[0044] The present invention can obtain the material of the bottom case and the required sandblasting effect before sandblasting the watch bottom case. Based on this processing and analysis, the corresponding sandblasting process is obtained to form the sandblasting process of the sandblasting equipment. Compare the sandblasting process with the sandblasting established process composed of the sandblasting process preset by the manual. According to the comparison result, judge the accuracy of the sandblasting established process of the sandblasting equipment, which is beneficial to reducing the occurrence of sandblasting error phenomena, ensuring the accuracy of the sandblasting on the surface of the bottom case. At the same time, the error points of the sandblasting process can be warned and corrected in time, further ensuring the efficiency of the sandblasting of the bottom case and reducing resource consumption.

[0051] Please refer to Figure 1 As shown in the figure, a method for sandblasting the surface of a wearable watch bottom case includes the following steps:

[0052] Step 1: Collect high-definition images of the surface of the bottom case to be sandblasted, extract the characteristic factors of the surface of the bottom case to be sandblasted from the images, identify and determine the material type of the bottom case to be sandblasted based on the characteristic factors, divide several types of materials, and set several sandblasting processes corresponding to the material types. Screen and match the material type of the bottom case to be sandblasted with several sandblasting processes, and select the sandblasting process with the highest matching rate and mark it as sandblasting process No. 2, which is set as the first sandblasting reference process of the sandblasting equipment;

[0053] 101. Establish an integrated monitoring facility for high-definition image collection at the entrance of the sandblasting equipment, and use the intelligent monitoring equipment to collect and intercept high-definition images of the bottom case surface;

[0054] 102. Extract the characteristic factors of the bottom shell surface from the image, including identification characters, glossiness, and color. Process the characteristic factors to obtain a characteristic index. Set several types of materials and number them in sequence. Process the characteristic factors corresponding to several types of materials to obtain a preset characteristic index. Match the characteristic index with the preset characteristic index. If the match is successful, mark the corresponding material number. If the match fails, mark it as a new type of material;

[0055] The specific process of processing the characteristic index is as follows: Obtain all the characteristic factors and substitute them into the formula TZ = BS×β1 + GZ×β2 + YS×β3 to obtain the characteristic index TZ. BS, GZ, and YS respectively represent the identification character, glossiness, and color values, and β1, β2, and β3 respectively represent the set weight factors;

[0056] Set several types of materials, including stainless steel, titanium metal, ceramic,... materials, and number them in sequence as ①, ②, ③,... in order, and set their corresponding characteristic factors;

[0057] For example: The stainless steel material is numbered ①, and its corresponding characteristic factors are: the identification character is A, the glossiness is 70 GU, and the color is 128R, 128G, 126B;

[0058] The titanium metal material is numbered ②, and its corresponding characteristic factors are: the identification character is T, the glossiness is 60 GU, and the color is 128R, 128G, 128B;

[0059] The ceramic material is numbered ③, and its corresponding characteristic factors are: the identification character is C, the glossiness is 65 GU, and the color is 240R, 248G, 255B;

BS', GZ', and YS' respectively represent the preset identification character, preset glossiness, and preset color values. According to different material types, the preset identification character can be BS1', BS2,..., the preset glossiness can be GZ1', GZ2,..., and the preset color can be YS1', YS2,.... Based on different material types, preset characteristic indices TZ1', TZ2',... can be obtained;

[0061] Match the characteristic index with the preset characteristic indices of several types of materials. If TZ ∈ (TZ', TZ1', TZ2',......), then obtain the material type that matches the bottom shell material, complete the determination of the bottom shell material to obtain the corresponding number. If

[0062] Then the material type that matches the bottom shell material is not obtained, and it is determined that the bottom shell material is a new type of material;

[0063] 103. Set sandblasting processes corresponding to several types of materials. Based on the material number marked on the bottom shell, match and obtain the corresponding sandblasting process, mark it as Sandblasting Process No. 2, and set it as Sandblasting Reference Process 1. If the material marked on the current bottom shell is a new material, execute it with Sandblasting Process No. 1 corresponding to the preset sandblasting process.

[0064] Set sandblasting processes corresponding to several types of materials. For example:

[0065] The sandblasting process corresponding to the stainless steel material number ①: particle diameter 0.15mm, particle hardness 8 degrees, shape spherical, sandblasting pressure 0.4MPa, sandblasting distance 150mm, sandblasting angle 20°, sandblasting time 10 seconds;

[0068] If the material number marked on the bottom shell is ①, it is successfully matched with the stainless steel material number ①, and the corresponding sandblasting process is: particle diameter 0.15mm, particle hardness 8 degrees, shape spherical, sandblasting pressure 0.4MPa, sandblasting distance 150mm, sandblasting angle 20°, sandblasting time 10 seconds;

[0070] Step 2: Obtain the type of sandblasting effect required on the surface of the bottom shell to be sandblasted. Based on the type of sandblasting effect, adjust the sandblasting parameters of Sandblasting Process No. 2 corresponding to Sandblasting Reference Process 1, and mark the sandblasting process No. 2 with adjusted sandblasting parameters as Sandblasting Process No. 3, and set it as Sandblasting Reference Process 2 of the sandblasting equipment;

[0071] 201. Obtain the type of sandblasting effect required on the surface of the bottom shell to be sandblasted, including uniform sandblasting, local sandblasting, and special sandblasting. Based on the selected type of sandblasting effect, adjust the sandblasting parameters of Sandblasting Process No. 2 corresponding to Sandblasting Reference Process 1;

[0072] Set sandblasting paths corresponding to several types of sandblasting effects. For example:

[0073] Uniform sandblasting: The corresponding sandblasting path extends horizontally in parallel straight lines with a length of 30 mm;

[0074] Local sandblasting: The corresponding sandblasting path extends horizontally in parallel straight lines with a length of 15 mm;

[0075] Special sandblasting: The corresponding sandblasting path extends horizontally in parallel curves with a length of 7.5 mm;

[0076] 202. Obtain the sandblasting parameters of the second sandblasting process, including the abrasive value and the sandblasting value, which together constitute the sandblasting parameters of the second sandblasting process. The abrasive value consists of the particle size, hardness, and shape values of the abrasive, and the sandblasting value consists of the sandblasting pressure, sandblasting distance, sandblasting angle, and sandblasting time values;

[0077] The specific process of processing the abrasive value and the sandblasting value is as follows: The abrasive value ML is obtained through the formula ML = KL×γ1 + YD×γ2 + XZ×γ3, where KL, YD, and XZ respectively represent the particle size, hardness, and shape values of the abrasive, and γ1, γ2, and γ3 represent the set weighting factors;

[0078] The sandblasting value PS is obtained through the formula PS = YL×δ1 + JL×δ2 + JD×δ3 + SJ×δ4, where YL, JL, JD, and SJ respectively represent the sandblasting pressure, sandblasting distance, nozzle angle, and sandblasting time values, and δ1, δ2, δ3, and δ4 represent the set weighting factors;

[0079] 203. The sandblasting parameters corresponding to the second sandblasting process are composed of the abrasive value and the sandblasting value. Based on the selected sandblasting effect type, the sandblasting path is obtained as an adjustment parameter. The parameters composed of the abrasive value, the sandblasting value, and the sandblasting path constitute the third sandblasting process, which is set as the second sandblasting reference process;

[0080] For example: Input the sandblasting path into the computer to construct a two-dimensional plan, set the two-dimensional plan that matches the surface of the bottom case, and control the extension of the sandblasting path on the two-dimensional plan according to the sandblasting effect type to obtain the sandblasting path simulation parameters;

[0081] If the material number marked on the current bottom case is ① and a uniform sandblasting effect is required, it is successfully matched with the stainless steel material number ①. The corresponding sandblasting process is as follows: The particle diameter is 0.15 mm, the particle hardness is 8 degrees, the shape is spherical, the sandblasting pressure is 0.4 MPa, the sandblasting distance is 150 mm, the sandblasting angle is 20°, the sandblasting time is 10 seconds, and it extends horizontally in parallel straight lines with a length of 30 mm;

[0082] Mark the current sandblasting process as the third sandblasting process and set it as the second sandblasting reference process.

[0083] Step 3: Obtain the preset sandblasting process of the sandblasting equipment, sum up the first sandblasting parameters of the sandblasting process corresponding to the preset sandblasting process to obtain the preset sandblasting index, sum up the third sandblasting parameters of the sandblasting process corresponding to the second reference sandblasting process to obtain the sandblasting index, calculate the index difference between the preset sandblasting index and the sandblasting index, process and analyze the index difference to obtain the matching degree between the preset sandblasting process and the second reference process, and determine whether the current preset sandblasting process is accurate based on the matching degree. If the matching degree is high, it is determined that the preset sandblasting process is accurate and a sandblasting instruction is generated. If the matching degree is low, it is determined that the preset sandblasting process is inaccurate and a warning instruction is generated;

[0084] 301. Obtain the first sandblasting parameters of the sandblasting process corresponding to the preset sandblasting process, including the preset abrasive value, the preset sandblasting value, and the preset sandblasting path parameters, and sum them up to obtain the preset sandblasting index;

[0085] The summation calculation of the preset sandblasting index is as follows: The preset sandblasting index PZ' is obtained through the formula PZ'=(ML'×ε1 + PS'×ε2)+(LJ'×ε3), where ML', PS', and LJ' respectively represent the preset abrasive value, the preset sandblasting value, and the preset sandblasting path parameters, and ε1, ε2, and ε3 respectively represent the set proportional coefficient factors;

[0086] 302. Obtain the third sandblasting parameters of the sandblasting process corresponding to the second reference sandblasting process, including the abrasive value, the sandblasting value, and the sandblasting path parameters, and sum them up to obtain the sandblasting index;

[0087] The summation calculation of the sandblasting index is as follows: The sandblasting index PZ is obtained through the formula PZ=(ML×ε1 + PS×ε2)+(LJ×ε3), where ML, PS, and LJ respectively represent the abrasive value, the sandblasting value, and the sandblasting path parameters;

[0088] 303. Substitute the preset sandblasting index and the sandblasting index into the formula ZC = |PZ'×φ1 - PZ×φ2| to obtain the index difference ZC, where φ1 and φ2 represent the set proportional coefficient factors. Set the index difference threshold ZC', and select the maximum value to the minimum value within its influence range to form the index difference threshold interval (-ZC', ZC', +ZC'). If ZC ∈ (-ZC', ZC', +ZC'), the matching degree is high, and it is determined that the preset sandblasting process is accurate and a sandblasting instruction is generated. If and > +ZC', the matching degree is low, and it is determined that the preset sandblasting process is inaccurate and a warning instruction is generated.

[0089] Step 4: Obtain the instruction. If the obtained instruction is a sandblasting instruction, control the sandblasting equipment to operate according to the preset sandblasting process to perform sandblasting treatment on the watch case. If the obtained instruction is a warning instruction, control the sandblasting equipment to suspend operation and transmit the warning signal to the mobile terminal of the management personnel;

[0090] 401.

In addition, set the sandblasting path of the spray gun structure, and jointly control the sandblasting equipment to perform the sandblasting operation;

[0091] 402. If the obtained instruction is a warning instruction, then control the sandblasting equipment to pause operation, analyze the warning instruction to obtain a warning node, generate a warning signal based on the warning node and transmit it to the mobile terminal of the management personnel. The management personnel can then quickly find the location of the warning problem according to the warning node and perform repairs;

[0092] Analyzing the warning instruction to obtain a warning node specifically means: inputting the abrasive value and its composition factors into a computer to construct a two-dimensional coordinate diagram. Use the abrasive value as the horizontal axis of the two-dimensional coordinate system, use the number of composition factors as each node on the horizontal axis of the two-dimensional coordinate system, use the value of the composition factor as the vertical axis of the two-dimensional coordinate system, and connect the marked coordinate points with a smooth curve to form an abrasive value curve diagram;

[0093] Input the sandblasting value and its composition factors into a computer to construct a two-dimensional coordinate diagram. Use the sandblasting value as the horizontal axis of the two-dimensional coordinate system, use the number of composition factors as each node on the horizontal axis of the two-dimensional coordinate system, use the value of the composition factor as the vertical axis of the two-dimensional coordinate system, and connect the marked coordinate points with a smooth curve to form a sandblasting value curve diagram;

[0094] Input the sandblasting path into a computer to construct a two-dimensional plan view, set a two-dimensional plan view that matches the surface of the bottom shell, and control the extension of the sandblasting path on the two-dimensional plan view according to the sandblasting effect type to obtain a sandblasting path simulation diagram;

[0095] Repeat the above process by substituting the preset abrasive value, preset sandblasting value, and preset sandblasting path to obtain the corresponding preset abrasive value curve diagram, preset sandblasting value curve diagram, and preset sandblasting path simulation diagram. Compare the corresponding diagrams of each, and the warning node between the preset sandblasting process and the sandblasting reference process No. 2 can be obtained according to the comparison error.

[0096] Step Five: Collect high-definition images of the surface of the bottom shell after sandblasting, compare them with the images of the surface of the qualified sandblasted bottom shell, find the difference points between the two images for processing to obtain the corresponding difference value, and perform processing and analysis on the difference value to obtain the qualified index of the bottom shell after sandblasting;

[0097] 501. By establishing an integrated monitoring facility for high-definition image collection at the outlet of the sandblasting equipment, use an intelligent monitoring device to collect and intercept high-definition images of the surface of the bottom shell;

[0099] The specific process of processing the difference value is as follows: count the number of difference points. If the number of difference points is greater than zero, set several difference ranges, and each difference range corresponds to an influence coefficient. If a difference point is within a difference range, match the influence coefficient corresponding to that difference range. Match all the difference points with several difference ranges respectively to obtain the corresponding influence coefficients, and then sum up the values corresponding to all the influence coefficients to obtain the total influence value. Input the values of the number of difference points and the total influence value into the computer. Use the value of the total influence value as the bottom circle radius and the value of the number of difference points as the height to establish a cylinder, select the volume of the cylinder and mark the volume value as the difference value.

[0100] 503. Set a difference threshold, and select the maximum value to the minimum value within its influence range to form a difference threshold interval. Match the difference value with the difference threshold interval. If the match is successful, it indicates that the difference value is small and the sandblasting qualification index is high, and mark the sandblasted bottom shell as a qualified product. If the match fails, it indicates that the difference value is large and the sandblasting qualification index is low, and mark the sandblasted bottom shell as a defective product.

[0101] Set the difference threshold CY', and select the maximum value to the minimum value within its influence range to form a difference threshold interval (-CY', CY', +CY'). Match the difference value CY with the difference threshold interval. If CY ∈ (-CY', CY', +CY'), the match is successful, indicating that the difference value CY is small and the corresponding sandblasting qualification index is high, and mark it as a qualified product. If and > +CY', the match fails, indicating that the difference value CY is large and the corresponding sandblasting qualification index is low, and mark it as a defective product.
