Detailed Description
The invention is further illustrated by the following figures and examples:
example 1:
as shown in fig. 1-2, the method for improving the grinding precision of the carrier plate glass by fixing and correcting the deviation, provided by the invention, comprises the following steps:
s1: after the carrier plate glass is taken out, the carrier plate glass is placed on a measuring platform, and straightness values of 4 sides are measured through a measuring device respectively;
s2: during measurement, one edge of the carrier plate glass is equally divided, the linearity is actually measured through a measuring device, and one value measured in each equally divided interval is a linearity value;
s3: the grinding quantity value of each edge of the carrier plate glass is fixed, and the deviation correcting quantity value is obtained by comparing the straightness accuracy value obtained by measuring in the step S2 with the determined grinding quantity value;
s4: inputting the deviation correcting quantity value obtained in the step S3 on the interface of the carrier plate glass grinding mechanism, and correcting the deviation of the grinding feed value;
s5: according to the initial value of the feeding amount of the carrier plate glass grinding mechanism and the numerical value of the deviation correcting amount, the actual feeding amount of the grinding mechanism is adjusted in real time according to the principle of more returning and less feeding, the purpose of correcting deviation and correcting is achieved, and the actual grinding amount of each edge of the carrier plate glass is ensured to be consistent.
The process of measuring the straightness value through the measuring device in the step S1 comprises the following steps:
s11; putting the carrier plate glass on a measuring platform, wherein sliding rails are respectively arranged at the edges of the measuring platform 4;
s12: the sliding rail is provided with a dial indicator which can radially move for a fixed distance;
s13: the dial indicator moves to two ends of one side of the carrier plate glass on the slide rail to move radially, when the dial indicator moves to a stroke, the position of the carrier plate glass is adjusted to enable the dial indicator head to contact the edge of the carrier plate glass, and the dial indicator returns to 0, namely measured values displayed by the dial indicators at two ends of one side of the carrier plate are consistent;
s14: and moving the dial indicator to each equally divided position, and reading the numerical value to obtain the linearity numerical value.
The working principle of the embodiment is as follows:
as shown in fig. 1-4, the carrier glass is fixed on the grinding table, and the grinding mechanism comprises a feeding unit which gives a certain feeding amount according to the requirement; the feeding unit advances at a set speed with the grinding cutter-in position as a starting point and the grinding cutter-out position as an end point.
The straightness test procedure is shown in fig. 3. If the side length to be measured is 1000mm, the side length to be measured is 10 parts per 100mm, the cutter feeding position is 0, the reading of the dial indicator returns to zero, the cutter discharging position is 1000, the reading is also 0 through fine adjustment, and the glass is ensured to be flat. Readings of 100,200, \8230 \ 8230; \ 900 position were confirmed using a dial gauge.
According to the principle of "more backward and less forward", as shown in fig. 4, corresponding parameters are set on the interface of the grinding machine to correct the deviation.
And continuing to fine-tune the parameters according to the corrected edge results. When the grinding feed amount is fixed, the grinding is performed more at the protruding position, and the cutter needs to be withdrawn more at the corresponding equal division position; the milling is less indicated at the recessed position, and more feed is required at the corresponding halved position. The grinding machine is provided with a corresponding correction interface to realize the function of 'more back and less forward'.
Example 2:
on the basis of the embodiment 1, when measuring in the step S2, one edge of the carrier plate glass is divided into N equal parts, and the size of the carrier plate glass is M, then each equal part length P = M/N, the straightness after sheet breaking is actually measured, and a numerical value is measured in each equal part interval, and corresponding parameters are set according to the numerical value.
The process of comparing the straightness value obtained by measurement in the step S3 with the determined grinding quantity value includes: the measured straightness value is subtracted from the determined abrasion amount value.
The glass carrying plate grinding mechanism in the step S4 comprises a feeding unit which gives a certain feeding amount according to the requirement; the feeding unit takes the grinding cutter-entering position as a starting point and the grinding cutter-exiting position as an end point and advances at a set speed.
The process of adjusting the feeding amount of the grinding mechanism in real time by the feeding unit in the step S5 comprises the following steps:
assuming that the initial value of the feeding amount is L, adjusting the feeding amount of each equally divided interval of the carrier plate glass in real time according to the advancing distance of the grinding mechanism, wherein the adjusted feeding amount is the sum of the initial value L of the feeding amount and the deviation correction amount.
The feeding unit of the support plate glass grinding mechanism is a grinding wheel, when the grinding wheel is initially set, the grinding feeding original point position is firstly confirmed, and the original point position is that the support plate glass just touches the outer diameter edge of the grinding wheel.
The grinding wheel does not contact the support plate glass when in standby, and needs to be retreated for a certain distance, so that the safety of the support plate glass is ensured.
When the grinding wheel is standby to reach the original point position, a certain error value exists, the error value needs to be corrected according to the actual grinding effect, the error value is obtained through measurement, and the actual feeding initial value is the error value plus the feeding initial value L.
For example, the linearity of the carrier glass measured after breaking is shown in FIG. 5 (unit: mm): as can be seen from fig. 5, the straightness of the carrier glass after sheet breaking fluctuates, and the value is the largest at the position where the knife is inserted and passes 300mm (hereinafter, 300mm is used instead) and reaches 0.04, while the value is the smallest at the position where the knife is inserted and passes 900mm (hereinafter, 900mm is used instead) and reaches-0.01.
For example, the required grinding amount is 0.03mm, the grinding amount at the cutter feeding position is adjusted to be 0.03mm by taking the cutter feeding position as a reference point, when no deviation rectifying function is performed, the theoretical value of the grinding amount at the 300mm position reaches 0.07, and the theoretical value of the grinding amount at the 900mm position is only 0.01mm, so that the quality problem of the edge part which is ground more or less occurs.
In order to make the grinding amount of 0.03mm on all sides, correction of the grinding feed value is required according to the straightness value, the operation is as shown in FIG. 7 (unit: mm), and the measured straightness value is compared with the determined grinding amount value to obtain the correction amount value;
after the deviation correction value is inputted to the grinding machine interface, the deviation correction of the grinding feed value is performed as shown in FIG. 8 (unit: mm).
According to the principle of multi-backward and small-forward, the actual feeding amount of the grinding mechanism is adjusted in real time according to the initial value of the feeding amount and the numerical value of the deviation correction amount of the carrier plate glass grinding mechanism, and if the initial value of the feeding amount is L, the data of the real-time adjustment of the feeding amount according to the grinding forward distance are shown in the following table 1:
table 1: data table for feed amount after correction
| Position (mm) | Feed rate (mm) |
| 0 | L |
| 100 | L-0.01 |
| 200 | L-0.03 |
| 300 | L-0.04 |
| 400 | L-0.03 |
| 500 | L-0.02 |
| 600 | L-0.01 |
| 700 | L |
| 800 | L+0.01 |
| 900 | L+0.02 |
| 1000 | L |
As shown in fig. 9, the lower curve is a schematic diagram of the feeding position after correction, and it can be seen from the diagram that the straightness of the carrier glass after breaking off and grinding is changed uniformly, and the grinding amount of the whole edge is theoretically consistent.
As shown in FIG. 10, the initial setting is performed by confirming the location of the origin of the lapping feed, which is generally the location where the lapping glass just touches the outer diameter edge of the lapping wheel.
As shown in fig. 11, the grinding wheel does not contact the glass during standby, and needs to be retracted for a certain distance to ensure the safety of the glass. If 100mm, the position of the feed coordinate "0".
Because the grinding wheel does not contact the glass when in standby, a certain error exists when the position of the feeding origin is determined, the error value needs to be corrected according to the actual grinding effect, if the error value is corrected by 0.1mm, the feeding amount is 100.1 (namely the initial value L of the feeding amount) during normal grinding.
The calculation results of the feed amount at each position after the final error correction are shown in the following table 2:
table 2: data sheet of final feed amount after error correction
| Position (mm) | Feed rate (mm) |
| 0 | 100.1 |
| 100 | 100.1-0.01=100.09 |
| 200 | 100.1-0.03=100.07 |
| 300 | 100.1-0.04=100.06 |
| 400 | 100.1-0.03=100.07 |
| 500 | 100.1-0.02=100.08 |
| 600 | 100.1-0.01=100.09 |
| 700 | 100.1 |
| 800 | 100.1+0.01=100.11 |
| 900 | 100.1+0.02=100.12 |
| 1000 | 100.1 |
