< method examples >
Fig. 1 shows a flowchart illustrating a control method of a cloth wheel polishing apparatus according to an embodiment of the present disclosure, which is applied to the cloth wheel polishing apparatus. The cloth wheel polishing device comprises a polishing cloth wheel and a displacement assembly. The polishing cloth wheel is used for polishing a product to be polished, and the displacement assembly is used for controlling the movement of the product to be polished, so that the polishing cloth wheel can polish the product to be polished.
As shown in fig. 1, the control method of the cloth wheel polishing apparatus provided by this embodiment may include the following steps S1100 to S1400.
Step S1100, when the polishing cloth wheel polishes the product to be processed, the current processing number of the polishing cloth wheel is obtained.
In this embodiment, the currently processed number of the polishing cloth wheel may include the number of the processed products of the polishing cloth wheel and the currently processed products. For example, when the buffing wheel processes the product for the first time, that is, when the buffing wheel processes the first product, the current processing number of the buffing wheel is 1. For example, when the buffing wheel processes the product for the 100 th time, that is, when the buffing wheel processes the 100 th product, the current processing number of the buffing wheel is 100.
Illustratively, the count is performed every time the buffing wheel processes a product. And counting once when the polishing cloth wheel polishes the product to be processed, and taking the counted numerical value as the current processing quantity of the polishing cloth wheel.
Step S1200, determining a current feed amount corresponding to the current machining amount according to the current machining amount, the mapping relationship between the machining amount and the feed amount.
In this embodiment, in the use of the polishing cloth wheel, the friction between the polishing cloth wheel and the product to be polished can cause the abrasion of the polishing cloth wheel, and further can affect the polishing effect of the polishing cloth wheel. In this regard, when the polishing cloth wheel is used to process a product each time, the current feeding amount can be determined according to the consumption of the polishing cloth wheel, and the compensation amount of the product processed each time can be determined according to the current feeding amount, so that the movement of the product to be polished can be controlled according to the compensation amount, and the polishing effect of the polishing cloth wheel can be ensured. Further, as the number of the polishing cloth wheels increases, the consumption of the polishing cloth wheels increases. That is, the current machining number of the polishing cloth wheel may reflect the current consumption of the polishing cloth wheel. Based on this, the current feed amount of the polishing cloth wheel can be determined according to the current machining number of the polishing cloth wheel.
In one embodiment, the determining, according to the current machining quantity and the mapping relationship between the machining quantity and the feed amount, the current feed amount corresponding to the current machining quantity includes: under the condition that the current machining quantity is in a first quantity range, determining that the current feed amount corresponding to the current machining quantity is a first feed amount; and under the condition that the current machining quantity is in a second quantity range, determining that the current feed amount corresponding to the current machining quantity is a second feed amount.
For example, the first number range is: the processing quantity is more than 1 and less than or equal to 400, and the first feeding quantity is 0.0135mm. The second number range is: the processing quantity is more than 400 and less than or equal to 800, and the second feeding quantity is 0.0137mm.
In the present embodiment, a mapping relationship between the machining number and the feed amount may be established in advance to determine a current feed amount corresponding to the current machining number based on the mapping relationship between the machining number and the feed amount.
For example, the mapping relationship between the machining number and the feed amount may be a one-to-one correspondence relationship between the machining number and the feed amount. For example, the mapping relationship between the machining number and the feeding amount may be a plurality of machining numbers corresponding to one feeding amount, that is, a range of the machining numbers corresponding to one preset feeding amount. The machining number range may include a first number range and a second number range, the preset feeding amount corresponding to the first number range is a first feeding amount, and the feeding amount corresponding to the second number range is a second feeding amount. For example, the first range of numbers is: the processing quantity is more than 1 and less than or equal to 400, and the first feeding quantity is 0.0135mm. The second number range is: the processing quantity is more than 400 and less than or equal to 800, and the second feeding quantity is 0.0137mm.
Next, a step of establishing a mapping relationship between the machining amount and the feed amount will be described.
In an alternative embodiment, the step of establishing a mapping relationship between the number of passes and the feed amount comprises: step S2100 to step S2300.
Step S2100, obtaining historical processing data of the polishing cloth wheel, wherein the historical processing data comprises preset initial feeding amount, the maximum diameter of the polishing cloth wheel and the corresponding current diameter when the polishing cloth wheel processes any product.
The preset initial feed amount may reflect an average consumption amount of the product per one process of the polishing cloth wheel. Illustratively, the buffing wheel is controlled to process 100 products, wherein the moving position of the products is adjusted according to a set fixed feeding amount for each processing, partial products are randomly grabbed from the 100 products to be detected, and in the case that all the grabbed partial products are qualified, all the 100 products are considered to be qualified, and at this time, the fixed feeding amount is used as a preset initial feeding amount. It should be noted that the preset initial feeding amount may be set according to practical experience or simulation experiment results, and the embodiment of the present disclosure does not limit this.
The maximum diameter of the polishing cloth wheel is the diameter of the polishing cloth wheel when the polishing cloth wheel is not processed.
The current diameter of the polishing cloth wheel for processing any product can be determined according to the maximum diameter of the polishing cloth wheel and the consumption of the polishing cloth wheel. The current diameter at the first machining of the product by the polishing cloth wheel is, for example, the maximum diameter of the polishing cloth wheel. Illustratively, the current diameter of the polishing cloth wheel at the ith processed product is the difference value between the maximum diameter of the polishing cloth wheel and the consumption of the polishing cloth wheel, wherein the consumption of the polishing cloth wheel is the feeding amount of the ith-1 processed product, and the ith processed product is a processing process except the first processed product.
After step S2100, step S2200 is performed to determine the feeding amount of any product processed by the buffing wheel according to the preset initial feeding amount, the maximum diameter of the buffing wheel and the corresponding current diameter when any product is processed by the buffing wheel.
In this embodiment, when the cloth wheel processes any product, if the set feeding amount is appropriate, the output power of the cloth wheel is stable. In this regard, based on the calculation formula of the output power of the polishing cloth wheel, the relationship between the maximum diameter of the polishing cloth wheel, the corresponding current diameter of the polishing cloth wheel when any one product is processed, and the feed amount can be determined.
This will be explained in detail below.
The calculation formula of the output power of the polishing cloth wheel is as follows:
output power of polishing cloth wheel = pressure of polishing cloth wheel x relative movement distance/processing time length (1)
The calculation formula of the relative movement distance is as follows:
relative movement distance = instantaneous linear speed of polishing cloth wheel x processing time (2)
The pressure of the polishing cloth wheel is calculated according to the following formula:
pressure of polishing cloth wheel = instantaneous linear velocity of polishing cloth wheel x friction coefficient x nip area (3)
The calculation formula of the instantaneous linear speed of the polishing cloth wheel is as follows:
instantaneous linear velocity of polishing cloth wheel = angular velocity of polishing cloth wheel x diameter of polishing cloth wheel (4)
The calculation formula of the pressing area is as follows:
pressing area = feed quantity x width of cloth wheel (5)
Substituting formula (2), formula (3), formula (4) and formula (5) into formula (1) to obtain:
output power of polishing cloth wheel = angular velocity of polishing cloth wheel 2 X diameter of polishing cloth wheel 2 X coefficient of friction
X feed amount x cloth wheel width (6)
When the processing parameters of the cloth wheel polishing equipment are determined, the angular speed, the friction coefficient and the width of the cloth wheel of the polishing cloth wheel are all constant values, and when any product is processed by the polishing cloth wheel, if the set feeding amount is appropriate, the output power of the polishing cloth wheel is stable. It can be seen that the magnitude of the feed is dependent on the diameter of the polishing cloth wheel.
Based on the above description, the feeding amount of any product processed by the polishing cloth wheel can be determined according to the preset initial feeding amount, the maximum diameter of the polishing cloth wheel and the corresponding current diameter when any product is processed by the polishing cloth wheel.
Illustratively, the formula for calculating the feed for processing any product is as follows:
the feed amount of any product processed by the polishing cloth wheel = the maximum diameter of the polishing cloth wheel 2 X preset initial feed/current diameter of polishing cloth wheel 2
More specifically, for the first time processed product, the corresponding feed amount of the first time processed product is the preset initial feed amount.
For the ith processed product, the corresponding feed amount of the ith processed product is determined according to the preset initial feed amount, the maximum diameter of the polishing cloth wheel and the current diameter of the ith processed product of the polishing cloth wheel, wherein the current diameter of the ith processed product is the difference between the maximum diameter of the polishing cloth wheel and the consumption amount of the ith-1 processed product, namely the difference between the maximum diameter of the polishing cloth wheel and the feed amount of the ith-1 processed product. Based on this, the feed amount to process any product can be determined.
After step S2200, step S2300 is executed to establish a mapping relationship between the machining quantity and the feeding quantity corresponding to any product machined by the polishing cloth wheel.
In this embodiment, a mapping relationship between the processing quantity and the feeding amount corresponding to any product processed by the polishing cloth wheel is pre-established according to the historical processing data of the polishing cloth wheel, and then after the current processing quantity of the polishing cloth wheel is obtained, the current feeding amount corresponding to the current processing quantity can be determined based on the pre-established mapping relationship, so that the accuracy of determining the feeding amount can be improved.
In one embodiment, the mapping relationship between the machining number and the feed amount is a mapping relationship between a machining number range and a preset feed amount, and the step of establishing the mapping relationship between the machining number range and the preset feed amount includes: step S3100 to step S3300.
Step S3100, obtaining historical processing data of the polishing cloth wheel, wherein the historical processing data comprise historical feeding amounts of a plurality of products which are continuously processed by the polishing cloth wheel and qualified in polishing parameters.
In one embodiment, the step of obtaining a historical feed of any of the plurality of products includes: and obtaining the historical feeding amount of any product according to the preset initial feeding amount, the maximum diameter of the polishing cloth wheel and the current diameter of the polishing cloth wheel when any product is processed.
Illustratively, for the first time processed product, the historical feed amount corresponding to the first time processed product is the preset initial feed amount.
For the ith processed product, the historical feed amount corresponding to the ith processed product can be determined according to the preset initial feed amount, the maximum diameter of the polishing cloth wheel and the current diameter of the ith processed product of the polishing cloth wheel. Wherein the current diameter of the ith processed product is the difference between the maximum diameter of the polishing cloth wheel and the consumption of the ith-1 processed product, namely the difference between the maximum diameter of the polishing cloth wheel and the historical feeding amount of the ith-1 processed product. Based on this, the historical feed for processing any product can be determined.
Step S3200, determining the processing quantity range of the plurality of products processed by the polishing cloth wheel, and determining a preset feeding amount according to the historical feeding amount of the plurality of products.
The range of process quantities may include a first range of quantities and a second range of quantities, for example, the first range of quantities being: the processing quantity is more than 1 and less than or equal to 400. The second number range is: the processing quantity is more than 400 and less than or equal to 800.
In an alternative embodiment, determining the preset feed amount corresponding to the processing number range according to the historical feed amounts of the plurality of products comprises: and determining the average value of the historical feed amounts of a plurality of products as a preset feed amount corresponding to the range of the processing number.
For example, taking the machining number range as 1 < the machining number ≦ 400 as an example, the average value of the historical feed amounts from machining the 1 st product to machining the 400 th product is taken as the preset feed amount corresponding to the machining number range.
In the embodiment, the average value of the historical feeding amounts of a plurality of products is determined as the preset feeding amount corresponding to the processing number range, and then the position of the product to be polished is adjusted according to the preset feeding amount, so that the control accuracy can be improved, and the defective rate of the cloth wheel polishing equipment can be reduced.
In another alternative embodiment, determining the preset feed amount corresponding to the processing number range according to the historical feed amounts of the plurality of products comprises: and determining the historical feed amount of the designated product in the plurality of products as a preset feed amount corresponding to the processing number range.
For example, taking the machining number range as 1 < the machining number ≦ 400 as an example, the historical feed amount for machining the 200 th product is taken as the preset feed amount corresponding to the machining number range.
In the embodiment, the historical feed amount of the designated product in the plurality of products is determined as the preset feed amount corresponding to the processing number range, and then the position of the product to be polished is adjusted according to the preset feed amount, so that the accuracy of control is improved, the calculation amount can be reduced, and the power consumption of equipment is reduced.
After step S3200, step S3300 is executed to establish a mapping relationship between the machining number range and the preset feed amount.
In this embodiment, a mapping relationship between the machining number range and the preset feed amount is established in advance, and according to the machining number range where the current machining number of the polishing cloth wheel is located, the current feed amount of the polishing cloth wheel is determined, the current compensation value is determined according to the current feed amount, and then the machining is performed according to the compensation value of the machined product, so that the stability of the machining of the product can be improved, the calculation amount can be reduced, and the power consumption of the equipment is reduced.
After step S1200, step S1300 is executed to determine the compensation value of the product processed this time according to the current feed amount and the compensation value of the product processed last time.
In one embodiment, when the polishing cloth wheel processes the product for the first time, the compensation value of the product for the first time is a preset initial compensation value.
For example, the preset initial compensation value may be equal to the preset initial feeding amount.
For example, for the ith processed product, the compensation value corresponding to the ith processed product may be determined according to the current feed amount corresponding to the ith processed product and the compensation value corresponding to the (i-1) th processed product. More specifically, the compensation value corresponding to the ith processed product may be calculated according to the following formula (7):
the compensation value of the ith processed product = the compensation value of the ith-1 th processed product + the current feed amount of the ith processed product (7)
After step S1300, step S1400 is executed to control the displacement assembly to move according to the compensation value of the product being processed, so that the product being processed is moved to the target processing position.
During specific implementation, the moving of the product to be processed is controlled to move to the target processing position through the movement of the displacement assembly according to the moving distance and the compensation value of the product to be processed, so that the polishing cloth wheel polishes the product to be processed. The moving distance of the processed product can be the position from the product placing table to the polishing cloth wheel. The displacement assembly may be a robot.
It should be noted that, steps S1100 to S1200 may be implemented by a PC, where the PC is connected to the displacement assembly, and after determining the compensation value of the product being processed, the PC outputs the compensation value of the product being processed to the displacement assembly, so that the displacement assembly controls the product being processed to move to the target processing position according to the compensation value of the product being processed. Therefore, the power consumption of the displacement assembly can be reduced, and the operation speed is improved.
In one embodiment, in the case of replacing the polishing cloth wheel, determining a compensation value of a product processed this time according to the current feed amount and a compensation value of a product processed last time comprises: acquiring a cloth wheel compensation value; and determining the compensation amount of the product processed this time according to the current feeding amount, the compensation amount of the product processed last time and the cloth wheel compensation value.
Wherein, the cloth wheel compensation value can reflect the size difference of the polishing cloth wheel before and after replacement.
More specifically, the compensation value corresponding to the ith processed product may be calculated according to the following equation (8): the compensation value of the ith processed product = the compensation value of the ith-1 processed product + the current feed amount of the ith processed product + the cloth wheel compensation value (8)
