example 1:
as shown in fig. 1-5, the automatic feed amount adjusting device for carrier glass grinding of the invention comprises carrier glass 1, a conveying mechanism 8, a positioning and pushing mechanism, a positioning and detecting mechanism, a grinding workbench 9, a grinding mechanism and a grinding control system, wherein the carrier glass 1 is placed on the conveying mechanism 8 and conveyed to the grinding workbench 9 through the conveying mechanism 8, the positioning and pushing mechanism is positioned at the outer side of the carrier glass 1, the carrier glass 1 is positioned and pushed in the conveying process, and the positioning and detecting mechanism is positioned at the outer side of the grinding workbench 9 and is in contact with the carrier glass 1 to realize the position detection of the carrier glass 1, and the conveying mechanism 8, the positioning and pushing mechanism, the positioning and detecting mechanism and the grinding mechanism are electrically connected with the grinding control system.
The positioning and propelling mechanism comprises positioning wheels and propelling wheels, the positioning wheels and the propelling wheels are distributed around the outside of the carrier plate glass 1, the positioning wheels comprise horizontal positioning wheels 3 and vertical positioning wheels 4, and the propelling wheels comprise horizontal propelling wheels 2 and vertical propelling wheels 5.
The positioning detection mechanism comprises a positioning detection head 10, a working support 12 is arranged outside the positioning detection head 10, a lifting mechanism 11 is arranged on the working support 12, and the lifting mechanism 11 is connected with the positioning detection head 10.
The positioning detection head 10 comprises a driver 13, a measurement head and a telescopic rod 20, wherein the driver 13 is connected with the measurement head through a connecting block 14, a part of the telescopic rod 20 stretches and contracts at the inner side of the measurement head, the other part of the telescopic rod 20 contacts with the carrier glass 1 at the outer side of the measurement head, and a position sensor 16 is arranged in the measurement head. The driver is a double-shaft air cylinder.
The position of the telescopic rod 20, which is in contact with the measuring head, is provided with a pressure spring 18, the position of the telescopic rod 20, which is in contact with the carrier glass 1, is provided with a contact sleeve 19, and the part of the telescopic rod 20, which is positioned at the inner side of the measuring head, is provided with a telescopic sleeve 17.
The measuring head is also connected with an air pipe 15, and the lower part of the measuring head is connected with a gland 22 and a locating pin 21.
The positioning wheel comprises a servo motor 6, and the servo motor 6 is connected with a positioning driving wheel 7.
In this embodiment, when the carrier glass 1 is transferred to the position of fig. 1 by the conveying mechanism 8, the 4 positioning wheel servomotors are in position control at this time and rotate to a set angle, so that the 2 positioning wheels 3 in horizontal direction are on a straight line, the 2 positioning wheels 4 in vertical direction are also on a straight line, the carrier glass 1 is roughly positioned, at this time, the servomotor 6 is changed from position control to torque control, and then the 4 pushing wheels are controlled by the air cylinder, so as to push the carrier glass 1 to an accurate position. The horizontal positioning wheel 3 and the vertical positioning wheel 4 are finely adjusted according to the torque of the servo motor 6.

For example, when the measuring head contacts the carrier glass 1, the telescopic rod 20 moves backward, compressing the spring, and the displacement sensor 16 measures the backward moving distance of the telescopic rod 20 to be 2mm, and the condition is assumed to be normal, so 2mm is the standard value. The feed rate of the grinding wheel grinder is controlled by the position information fed back from the displacement sensor 16.
When the carrier glass 1 is conveyed to the grinder, it is conveyed to a position designated by a station before grinding by the conveying mechanism 8. The carrier glass 1 is positioned at an approximate position by four positioning wheels (rough positioning).

The positioning detection mechanism descends to a set position, and after the glass is positioned at a relatively accurate position through the positioning wheel (final positioning), the glass position information is determined through the measuring head.
During the actual transportation and positioning of the glass, the position of the glass is slightly changed due to the deviation between the actions. The degree of glass deflection is determined by measuring the data collection and comparing it with a reference value.
After the glass offset information is obtained by the grinding mechanism, the feeding amount is automatically calculated through a program, so that the grinding amount is ensured to be basically consistent.
When the abnormality occurs and the glass exceeds a certain deviation degree, in order to ensure that the grinding wheel and the glass are not damaged, the upper and lower alarm limits can be set, the equipment is stopped by an alarm before grinding, and a person is prompted to confirm the reason.

9. The automatic adjustment method for glass grinding feed rate according to claim 8, wherein: in the step S4, the detection of the offset information of the carrier glass 1 by the positioning detection head 10 specifically includes the following steps:
s11: firstly, adjusting the angle parameters of a positioning wheel to enable the position of the carrier glass 1 to be at a non-offset position, and setting a measured value at the moment as a reference value into the parameters;
s12: when the position of the carrier glass 1 is inconsistent with the initial state, the position information of the telescopic rod 20 is measured by the displacement sensor 16, and the current actual measured value is compared with the reference value;

In step S13, the polishing control system sets a threshold value of the offset, and when the detected offset exceeds the threshold value, the system stops the apparatus by warning before polishing, and prompts personnel to confirm the cause.
Specific examples are as follows:
in the initial setting, if the glass is adjusted to be relatively aligned, and the measured value H1 is 2 and H2 is 2 at this time, as shown in fig. 6, 2 is set to the reference value of H1 and H2, that is, the value measured by the subsequent glass is equal to the reference value, and the state of the glass is considered to be not shifted, and the indication to the grinder is to keep the cutting value uniform over the whole edge.
When the position of the carrier glass 1 is not consistent with the state of fig. 6, the displacement sensor 16 compares the current actual measurement value with the reference value as shown in fig. 7.
By comparison, assuming that the actual value measured by H1 at this time is 1.8, with 1.8-2 (reference value) = -0.2, the indication to the grinding wheel grinder is that the feed amount is 0.2mm less than the reference value;
the actual value of H2 measurement was 2.2, and the feed amount was 0.2mm more than the reference value by 2.2-2 (reference value) = +0.2, which is an indication to the grinding wheel grinder.
By the above description, it is known that the amount of correction of the cut-off value can be intelligently determined by comparing the measurement reference side with the measured value, so that the grinding amount is ensured to be basically consistent, and the processing quality is ensured.
