Description

Technical Field

[0001] The invention relates to the technical field of sandblasting the surface of a bottom case of a watch, and in particular to a method for sandblasting the surface of a bottom case of a wearable watch. Background Art

[0002] As a portable timing tool worn on the wrist, a wearable watch not only has a timing effect but also has a certain decorative function. In order to improve the appearance texture of the watch and increase its 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 adding modern and personalized elements.

[0003] When sandblasting the surface of a watch bottom case with existing sandblasting equipment, the sandblasting equipment can only sandblast the surface of the bottom case according to a predetermined process consisting of manually pre-set sandblasting techniques. Its autonomous intelligence level is low, and it is difficult to identify the specific condition of the watch case to determine whether the sandblasting process is correct, resulting in sandblasting errors. At the same time, sandblasting anomalies caused by the established process cannot be prevented in a timely manner, which can easily increase cost losses while affecting sandblasting efficiency.

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

[0008] Step 2: obtaining the type of sandblasting effect required for the bottom shell surface to be sandblasted, adjusting the sandblasting parameters of the sandblasting process No. 2 corresponding to the sandblasting reference process No. 1 based on the sandblasting effect type, marking the sandblasting process No. 2 after the sandblasting parameters are adjusted as the sandblasting process No. 3, and setting it as the sandblasting reference process No. 2 of the sandblasting equipment;

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

[0010] Step 4: Acquire the instruction. If the acquired instruction is a sandblasting instruction, control the sandblasting equipment to operate according to the preset sandblasting process to sandblast the watch case. If the acquired instruction is a warning instruction, control the sandblasting equipment to suspend operation and transmit the warning signal to the mobile terminal of the manager.

[0011] Step 5: Collect a high-definition image of the bottom shell surface after sandblasting, compare it with the surface image of the bottom shell of the qualified sandblasting product, find the difference points of the two images, process them to obtain the corresponding difference values, and process and analyze the difference values ​​to obtain the qualified index of the bottom shell after sandblasting.

If the current bottom shell marked material is a new material, the sandblasting process No. 1 corresponding to the preset sandblasting process is executed.

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

[0021] 203. The sandblasting parameters of the sandblasting process No. 2 corresponding to the sandblasting process No. 1 are formed by the abrasive value and the sandblasting value. The sandblasting path is obtained based on the selected sandblasting effect type and is set as an adjustment parameter. The sandblasting process No. 3 is formed by the parameters composed of the abrasive value, the sandblasting value and the sandblasting path and is set as the 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: the abrasive value ML is obtained by the formula ML=KL×γ1+YD×γ2+XZ×γ3, wherein KL, YD, and XZ represent the particle size, hardness, and shape values ​​of the abrasive, respectively, and γ1, γ2, and γ3 represent the set weight factors;

[0026] The preset sandblasting index is calculated by summing up: The preset sandblasting index PZ' is obtained by the formula PZ'=(ML'×ε1+PS'×ε2)+(LJ'×ε3), where ML', PS', and LJ' represent the preset abrasive value, the preset sandblasting value, and the preset sandblasting path parameter, respectively.

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

[0028] 302. Acquire the blasting parameters of the blasting process No. 3 corresponding to the blasting reference process No. 2, including the abrasive value, the blasting value and the blasting path parameter, and perform sum calculation to obtain the blasting index;

[0029] The sandblasting index is calculated by summing up: The sandblasting index PZ is obtained by the formula PZ = (ML × ε1 + PS × ε2) + (LJ × ε3), where ML, PS, and LJ represent the abrasive value, sandblasting value, and sandblasting path parameters, respectively;

[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', 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'), then the consistency is high, and it is determined that the preset sandblasting process accurately generates the sandblasting instruction, if And >+ZC', the consistency is low, and it is determined that the preset sandblasting process is inaccurate and a warning instruction is generated.

[0031] As a further improvement of the present invention, step 4 is specifically analyzed as follows:

[0032] 401. If the acquired instruction is a sandblasting instruction, according to the sandblasting process No. 1 corresponding to the preset sandblasting process, the abrasive particle size, hardness and shape corresponding to the abrasive value are selected, and the spray gun structure of the sandblasting equipment is set according to the sandblasting pressure, sandblasting distance, sandblasting angle and sandblasting time corresponding to the sandblasting value, and the sandblasting path of the spray gun structure is set, and the sandblasting equipment is controlled in combination to perform the sandblasting operation;

[0033] 402. If the acquired instruction is a warning instruction, the sandblasting equipment is controlled to suspend operation, and the warning instruction is analyzed to obtain a warning node. A warning signal is generated based on the warning node and transmitted to the mobile terminal of the manager. The manager can quickly find the warning problem according to the warning node and repair it.

[0034] As a further improvement of the present invention, the early warning instruction is analyzed to obtain the early warning node, specifically: the abrasive value and its component factors are input into the computer to construct a two-dimensional coordinate diagram, the abrasive value is the horizontal axis of the two-dimensional coordinate system, the number of component factors is each node on the horizontal axis of the two-dimensional coordinate system, the value of the component factor is the vertical coordinate of the two-dimensional coordinate system, and the marked coordinate points are connected with a smooth curve to form an abrasive value curve diagram;

[0037] Repeat the above process and substitute 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 graphs accordingly, and based on the comparison error, the early warning nodes of the preset sandblasting process and the sandblasting reference process 2 can be obtained.

[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 exit of the sandblasting equipment, the high-definition image of the bottom shell surface is collected and intercepted using intelligent monitoring equipment;

[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 means that the difference value is small, the sandblasting qualified index is high, and the sandblasted bottom shell is marked as a qualified product, if the match fails, it means that the difference value is large, the sandblasting qualified index is low, and the sandblasted bottom shell is marked as a defective product.

[0042] As a further improvement of the present invention, the specific process of processing the difference value is: counting the number of difference points, if the number of difference points is greater than zero, setting several difference ranges, each difference range corresponds to an influence coefficient, if the difference point is within the difference range, matching the influence coefficient corresponding to the difference range, matching all the difference points with several difference ranges respectively to obtain the corresponding influence coefficients, and then summing up the values ​​corresponding to all the influence coefficients to obtain the total value of the shadow system, inputting the values ​​of the number of difference points and the total value of the shadow system into the computer, establishing a cylinder with the value of the total value of the shadow system as the base circle radius and the value of the number of difference points as the height, selecting the volume of the cylinder and marking the volume value as the difference value.
