Description

Compensation method for product polishing push amount Technical Field

[0001] This invention relates to the field of product polishing technology, and specifically to a method for compensating for the amount of material pushed during product polishing. Background Technology

[0002] In the polishing process, the diameter of the polishing wheel will decrease due to wear and tear caused by high-speed friction. Therefore, in order to ensure the consistency of product quality after polishing, it is necessary to constantly adjust the relative position of the product and the polishing wheel according to the wear of the polishing wheel.

[0003] Currently, product feeding devices can only compensate for the wear of the polishing wheel using the actual feed rate. However, the actual feed rate is usually a fixed value set manually by the machine operator, which is an inaccurate estimate. It relies entirely on the operator's experience to set the feed rate. As a result, some products will gradually become under-polished or over-polished (excessive removal) over time. This can lead to rework or even scrapping. This process not only wastes time and greatly affects the polishing efficiency, but also limits the polishing yield due to the generation of scrap. Summary of the Invention

[0004] To address the aforementioned deficiencies in existing technologies, this invention provides a method for compensating for the amount of product polishing push. This method achieves automatic compensation of the product's push amount, effectively solving the problems of inadequate or excessive polishing, and improving the product's polishing efficiency and yield.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] The method for compensating for the amount of product polishing push includes the following steps:

[0007] S1. The product pushing device drives the control switch to move so that the control switch contacts the worn polishing wheel on the polishing device. When the polishing wheel triggers the control switch, the product pushing device stops moving. At the same time, the control system compares the current position of the product pushing device with the initial position of the product pushing device detected when the polishing wheel was not worn, and obtains the target pushing amount of the product pushing device.

[0008] S2. The control system calculates the push compensation amount based on the target push amount and the actual push amount after the product push device has undergone a preset number of feeds, and adjusts the position of the product push device according to the push compensation amount to realize automatic compensation of the actual push amount.

[0009] Furthermore, it also includes the following steps:

[0010] S3. The control system calculates the feed compensation amount based on the push compensation amount and the preset feed number, and automatically compensates the actual feed amount of the product push device based on the feed compensation amount, so that the actual feed amount reaches the target feed amount.

[0011] Further, in step S2, the initial position is A0, the current position is A1, the target push amount is A, the actual feed amount is D1, the preset feed count is N, the actual push amount is B, the push compensation amount is C, A = A1 - AO, B = D1 × N, and C = AB.

[0012] Further, in step S3, the feed compensation amount is D0, the target feed amount is D2, D0 = C ÷ N, D2 = D1 + D0.

[0013] Furthermore, prior to step S1, the following steps are performed:

[0014] S0. Before the polishing wheel wears out, the product pushing device drives the control switch to move so that the control switch contacts the polishing wheel. When the polishing wheel triggers the control switch, the product pushing device stops moving, and the position of the product pushing device at this time is taken as the initial position.

[0015] Furthermore, the product pushing device includes a robotic arm and a product fixing fixture mounted on the robotic arm, a control switch is mounted on the product fixing fixture, and the control switch and the robotic arm are electrically connected to the control system.

[0016] Furthermore, the product fixing fixture includes a fixed base, a telescopic power component, and a pressure head. The fixed base is disposed on the robotic arm. The telescopic power component is disposed within the fixed base, and the telescopic part of the telescopic power component extends out of the fixed base and connects to the pressure head. The pressure head is used to press the product onto the fixed base under the drive of the telescopic power component.

[0017] Furthermore, the control switch includes a mounting bracket, a first connecting rod, a second connecting rod, a linkage assembly, an elastic element, a contact block, and a distance sensor. The mounting bracket is fixedly mounted on the product fixing fixture. The first connecting rod and the linkage assembly are slidably mounted on the mounting bracket, and their sliding directions are the same. The second connecting rod is hinged between the first connecting rod and the linkage assembly, and the second connecting rod is also hinged to the mounting bracket. The contact block is mounted on the first connecting rod, and the elastic element is sleeved on the first connecting rod and located between the contact block and the mounting bracket. The distance sensor is mounted on the linkage assembly, and the distance sensor is electrically connected to the control system.

[0018] Furthermore, the linkage component includes two third links slidably disposed on the mounting bracket, and a hinge block disposed on the two third links, the hinge block being hinged to the second link, and the distance sensor being disposed on the hinge block.

[0019] Furthermore, the polishing device includes a base and a rotary drive member disposed on the base, wherein the polishing wheel is disposed on the rotary drive member and is driven to rotate by the rotary drive member.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are:

[0021] The product polishing push amount compensation method provided by this invention involves moving a control switch via a product push device to contact the worn polishing wheel on the polishing device. The product push device applies pressure to the polishing wheel, forcing it to trigger the control switch and stop the product push device. The control system then compares the current position of the product push device with its initial position when the polishing wheel was unworn to determine the target push amount (equivalent to the wear amount of the polishing wheel). The control system then calculates the push compensation amount based on the target push amount and the actual push amount after a preset number of feeds. Based on this compensation amount, the position of the product push device is adjusted to automatically compensate for the actual push amount. Compared with existing technologies, this invention's product polishing push amount compensation method achieves automatic compensation, effectively solving the problems of inadequate or excessive polishing, and improving polishing efficiency and yield.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0027] As shown in Figures 1 to 3, a method for compensating the amount of product polishing push is provided. This method is applicable to polishing equipment, which specifically includes a polishing device, a product pushing device, and a control system. The product pushing device includes a robotic arm (not shown in the figure) and a product fixing fixture 1 mounted on the robotic arm. A control switch 2 is mounted on the product fixing fixture 1. The control switch 2 and the robotic arm are electrically connected to the control system (not shown in the figure). The polishing device includes a base 3 and a rotary drive 4 mounted on the base 3. A polishing wheel 5 is mounted on the rotary drive 4 and is driven to rotate by the rotary drive 4.

[0028] The compensation method for product polishing push amount in this embodiment includes the following steps:

[0029] S0. Before the polishing wheel 5 wears out, the product pushing device drives the control switch 2 to move so that the control switch 2 contacts the polishing wheel 5. When the polishing wheel 5 triggers the control switch 2, the product pushing device stops moving and takes the position of the product pushing device at this time as the initial position.

[0030] S1. The product pushing device drives the control switch 2 to move so that the control switch 2 contacts the worn polishing wheel 5 on the polishing device. When the polishing wheel 5 triggers the control switch 2, the product pushing device stops moving. At the same time, the control system compares the current position of the product pushing device with the initial position of the product pushing device detected when the polishing wheel was not worn, and obtains the target pushing amount of the product pushing device (equivalent to the wear amount of the polishing wheel).

[0031] S2. The control system calculates the push compensation amount based on the target push amount and the actual push amount after the product push device has passed the preset number of feeds, and automatically compensates for the actual push amount based on the push compensation amount.

[0032] In the above steps, the initial position is A0, the current position is A1, the target push amount is A, the actual feed amount is D1, the preset feed count is N, the actual push amount is B, the push compensation amount is C, A = A1 - AO, B = D1 × N, and C = AB.

[0033] By adopting the above method, automatic compensation of product polishing push amount is achieved, which reduces the time wasted due to machine adjustment by the machine adjustment personnel, reduces the workload of employees, and at the same time can more accurately monitor the wear of polishing wheel 5, effectively solving the problem of inadequate or over-polishing of products, and improving the polishing efficiency and polishing yield of products.

[0034] The compensation method for product polishing push amount in this embodiment also includes the following steps:

[0035] S3. The control system calculates the feed compensation amount based on the push compensation amount and the preset feed number, and automatically compensates the actual feed amount of the product push device according to the feed compensation amount, so that the actual feed amount reaches the target feed amount.

[0036] In the above steps, the feed compensation is D0, the target feed is D2, D0 = C ÷ N, and D2 = D1 + D0.

[0037] By automatically correcting the actual feed amount D1 to the target feed amount D2, it is beneficial to improve the polishing accuracy of the next round of products and further improve the phenomenon of inadequate or over-polishing of products during the polishing process.

[0038] In the product polishing push amount compensation method of this embodiment, the product fixing fixture 1 is used to fix the product (not shown in the figure) to ensure the polishing accuracy of the product. The product fixing fixture 1 includes a fixing base 11, a telescopic power component 12, and a pressure head 13. The fixing base 11 is mounted on the robot arm; the telescopic power component 12 is mounted inside the fixing base 11, and the telescopic part of the telescopic power component 12 extends out of the fixing base 11 and connects to the pressure head 13; the pressure head 13 is used to press the product onto the fixing base 11 under the drive of the telescopic power component 12. Of course, other structural forms of product fixing fixtures can also be used, such as clamps driven by gripper cylinders, etc., and this embodiment does not limit this.

[0039] In this embodiment, the telescopic power component 12 is preferably a telescopic cylinder. The telescopic rod of the telescopic cylinder passes through the fixed seat 11 and is threadedly connected to the bolt 14. The pressure head 13 is rotated and sleeved on the bolt 14. Of course, the telescopic power component 12 can also be a telescopic electric cylinder or a telescopic hydraulic cylinder. This embodiment does not limit this.

[0040] Since the product in this embodiment has an elongated hole, the pressure head 13 is set to be elongated. When fixing the product, after the pressure head 13 passes through the elongated hole of the product, the pressure head 13 is rotated to make it misalign with the elongated hole of the product. Then, the telescopic cylinder drives the pressure head 13 to move and press the product onto the fixing seat 11 to fix the product.

[0041] The control switch 2 used in this embodiment includes a mounting bracket 21, a first connecting rod 22, a second connecting rod 23, a linkage component 24, an elastic element 25, a contact block 26, and a distance sensor 27. The mounting bracket 21 is fixedly mounted on the fixing seat 11 of the product fixing fixture 1. The first connecting rod 22 and the linkage component 24 are slidably mounted on the mounting bracket 21, and their sliding directions are the same. The second connecting rod 23 is hinged between the first connecting rod 22 and the linkage component 24 (the hole at the hinge is an oblong hole), and the second connecting rod 23 is also hinged on the mounting bracket 21. The contact block 26 is disposed on the first connecting rod 22 for contacting the polishing wheel 5. The elastic element 25 is sleeved on the first connecting rod 22 and located between the contact block 26 and the mounting bracket 21. The distance sensor 27 is disposed on the linkage component 24, and the distance sensor 27 is electrically connected to the control system.

[0042] In this embodiment, the product pushing device uses the contact block 26 of the control switch 2 to provide a certain pressure to the polishing wheel 5, thereby forcing the polishing wheel 5 to trigger the control switch 2 to stop the product pushing device. Its main purpose is to simulate the product contacting the polishing wheel 5 through the contact block 26, so as to ensure the accuracy of the target pushing amount (equivalent to the wear amount of the polishing wheel).

[0043] The mounting bracket 21 in this embodiment includes a first mounting block 211, a second mounting block 212, a third mounting block 213, and a fourth mounting block 214. The first mounting block 211 and the second mounting block 212 are parallel and spaced apart. The third mounting block 213 is vertically connected between the first mounting block 211 and the second mounting block 212. The fourth mounting block 214 is vertically connected to the second mounting block 212, and the fourth mounting block 214 and the third mounting block 213 are located on opposite sides of the second mounting block 212. In practical applications, the mounting bracket 21 can also adopt other structures, and this embodiment does not limit this.

[0044] In this embodiment, the first connecting rod 22 passes through the third mounting block 213 and is slidably disposed on the third mounting block 213; the linkage component 24 is slidably disposed on the fourth mounting block 214; the second mounting block 212 is provided with a through hole, the second connecting rod 23 is hinged in the through hole, and the two ends of the second connecting rod 23 extend out of the through hole and are hinged to the ends of the first connecting rod 22 and the linkage component 24, respectively; the contact block 26 is disposed on the unhinged end of the first connecting rod 22.

[0045] The linkage component 24 in this embodiment includes two third connecting rods 241 slidably disposed on the fourth mounting block 214 of the mounting frame 21, and a hinge block 242 disposed on the two third connecting rods 241. The hinge block 242 is hinged to the second connecting rod 23, and the distance sensor 27 is disposed on the hinge block 242.

[0046] Since the distance sensor 27 is mounted on the hinge block 242, in order to ensure the measurement accuracy of the distance sensor 27, both third connecting rods 241 in this embodiment are preferably equal-height bolts. The two equal-height bolts pass through the fourth mounting block 214 and are threadedly connected to the hinge block 242. The fourth mounting block 214 is also provided with a detection element 28 that cooperates with the distance sensor 27.

[0047] In this embodiment, the distance sensor 27 can be a magnetic displacement sensor, a laser displacement sensor, or an infrared distance sensor, depending on the specific requirements. This embodiment does not impose any restrictions on this.

[0048] To further improve the measurement accuracy of the distance sensor 27, linear bearings are respectively provided on the third mounting block 213 and the fourth mounting block 214 of the mounting frame 21, and the first connecting rod 22 and the two third connecting rods 241 are respectively slidably arranged in the corresponding linear bearings.

[0049] In this embodiment, the rotary drive 4 is preferably a motor, and the polishing wheel 5 is mounted on the drive shaft of the motor.

As can be seen from the above embodiments, the product polishing push amount compensation method of the present invention achieves automatic compensation of the product polishing push amount, effectively solving the problems of incomplete or excessive polishing, and improving the polishing efficiency and yield of the product.
