Detailed Description
The invention is further illustrated by the following figures and examples:
example 1:
as shown in fig. 1-5, the automatic feed amount adjusting device for grinding carrier plate glass according to the present invention comprises a carrier plate glass 1, a conveying mechanism 8, a positioning propulsion mechanism, a positioning detection mechanism, a grinding workbench 9, a grinding mechanism and a grinding control system, wherein the carrier plate glass 1 is placed on the conveying mechanism 8, and is conveyed to the grinding workbench 9 through the conveying mechanism 8, the positioning propulsion mechanism is located at the outer side of the carrier plate glass 1, and is used for positioning and propelling the carrier plate glass 1 during the conveying process, the positioning detection mechanism is located at the outer side of the grinding workbench 9 and is in contact with the carrier plate glass 1 to achieve position detection of the carrier plate glass 1, and the conveying mechanism 8, the positioning propulsion mechanism, the positioning detection mechanism and the grinding mechanism are electrically connected to the grinding control system.
The positioning and propelling mechanism comprises positioning wheels and propelling wheels, the positioning wheels and the propelling wheels are distributed on the periphery of the outer portion 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 measuring head and a telescopic rod 20, wherein the driver 13 is connected with the measuring head through a connecting block 14, one part of the telescopic rod 20 extends and retracts inside the measuring head, the other part of the telescopic rod 20 is contacted with the carrier plate glass 1 outside the measuring head, and a position sensor 16 is arranged inside the measuring head. The driver is a double-shaft cylinder.
A pressure spring 18 is arranged at the contact position of the telescopic rod 20 and the measuring head, a contact sleeve 19 is arranged at the contact position of the telescopic rod 20 and the carrier plate glass 1, and a telescopic sleeve 17 is arranged at the part of the telescopic rod 20 positioned at the inner side of the measuring head.
The measuring head is also connected with an air pipe 15, and a gland 22 and a positioning pin 21 are connected below the measuring head.
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 conveyed to the position shown in fig. 1 by the conveying mechanism 8, the servo motors of the 4 positioning wheels perform position control at this time, and rotate to a set angle, so that the 2 positioning wheels 3 in the horizontal direction are in a straight line, and the 2 positioning wheels 4 in the vertical direction are also in a straight line, to perform coarse positioning on the carrier glass 1, at this time, the servo motors 6 change the position control into torque control, and then the cylinders control the 4 pushing wheels to push the carrier glass 1 to an accurate position. The horizontal direction positioning wheel 3 and the vertical direction positioning wheel 4 are finely adjusted according to the torque of the servo motor 6. Then the positioning propulsion mechanism is loosened, the conveying mechanism 8 continues conveying, the grinding machine is conveyed to the position shown in the figure 3, the conveying mechanism 8 falls down, the support plate glass 1 is placed on the grinding workbench 9, the positioning detection mechanism falls down to the working position at the moment, the positioning detection head 10 starts working, the double-rod cylinder extends out, the positioning pin 21 is pushed against the workbench 9, the measuring head contacts the support plate glass 1, the telescopic rod 20 moves backwards at the moment, the intracavity displacement sensor 16 measures the distance of the backward movement of the telescopic rod 20, and position data are fed back by measuring the distance of the movement of the telescopic rod 20 to control the feed amount of the grinding wheel grinder. For example, after the measuring head contacts the carrier plate glass 1, the retractable rod 20 moves backwards, the spring is compressed, and the displacement sensor 16 measures that the distance of the retractable rod 20 moving backwards is 2mm, and it is assumed that this state is a normal state, so 2mm is a standard value. The feed amount of the grinding wheel grinder is controlled by the position information fed back by the displacement sensor 16.
When the carrier glass 1 is conveyed to the grinding machine, it is conveyed to a position designated by a pre-grinding station by the conveying mechanism 8. The carrier plate glass 1 is positioned in the rough position by four positioning wheels (rough positioning). After the glass is conveyed from the pre-polishing station to the middle polishing station, the conveying mechanism 8 descends to drop the glass onto the polishing table 9. 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.
In the actual conveyance and positioning of glass, the position of the glass is slightly changed due to variations between the respective operations. The degree of glass deflection is determined by measurement data collection and comparison with a reference value.
After the grinding mechanism obtains the glass offset information, the feed amount is automatically calculated through a program, and the grinding amount is ensured to be basically consistent.
When the glass exceeds a certain offset degree due to abnormity, in order to ensure that the grinding wheel and the glass are not damaged, the upper limit and the lower limit of alarm can be set, the equipment is shut down through alarm before grinding, and the personnel is prompted to confirm the reason.
Example 2:

s3: the method comprises the following steps of accurately positioning the carrier plate glass 1 through a positioning wheel, lowering a positioning detection mechanism to a set position after the carrier plate glass 1 is positioned at a relatively accurate position, and determining the position information of the carrier plate glass 1 through a positioning detection head 10;
s4: the offset information of the carrier plate glass 1 is detected by the positioning detection head 10, the positioning detection head 10 transmits the detected data to the grinding control system, and the grinding control system controls the feed amount of the grinding mechanism to ensure that the grinding amount is kept consistent.
9. The method for automatically adjusting the feed rate for glass polishing according to claim 8, characterized in that: the step S4 of detecting the offset information of the carrier plate glass 1 by positioning the detection head 10 specifically includes the following steps:
s11: firstly, adjusting the angle parameters of the positioning wheel to enable the position of the carrier plate glass 1 to be in a non-offset position, and setting the measured value as a reference value into the parameters;
s12: when the position of the carrier plate glass 1 is inconsistent with the initial state, the position information of the telescopic rod 20 is measured through the displacement sensor 16, and the current actual measured value is compared with the reference value;
s13: and subtracting the reference value from the measured value detected in the step S12 to obtain the offset of the carrier plate glass 1, and then instructing the grinding control system to the grinding wheel grinding mechanism to control the feed amount of the grinding wheel grinding mechanism to increase or decrease the corresponding offset.
In step S13, the polishing control system sets a threshold value for the amount of deviation, and when the detected amount of deviation exceeds the threshold value, the polishing control system gives an alarm to stop the apparatus before polishing, and prompts a person to confirm the cause.
Specific examples are as follows:
assuming that the glass is adjusted to be relatively aligned during initial setting, as shown in fig. 6, when the measured value H1 is 2 and the measured value H2 is 2, 2 is set as a reference value of H1 and H2, that is, when the measured value of the subsequent glass is equal to the reference value, it is considered that the state of the glass is not deviated, and the instruction to the grinder is to maintain a uniform cut value all the way.
When the position of the carrier plate glass 1 does not coincide 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 contrast, assuming that the actual value measured at this time by H1 is 1.8 and 1.8-2 (reference value) — 0.2, the indication to the wheel grinder is that the feed amount is 0.2mm less than the reference value;
h2 measured an actual value of 2.2, and with 2.2-2 (reference value) +0.2, the indication to the wheel grinder was that the feed was 0.2mm more than the reference value.
Through the above description, it can be known that the amount of the cut-in value which needs to be corrected can be intelligently judged by comparing the measured reference side with the measured value, so that the grinding amount is kept basically consistent, and the processing quality is ensured.
By adopting the automatic feed amount adjusting device and the automatic feed amount adjusting method for grinding the carrier plate glass, which are described in the embodiment of the invention with reference to the drawings, the offset of the glass can be detected in the grinding process, the feed amount of the grinding mechanism is adjusted according to the detected offset, the glass can be still normally ground under the condition of a certain offset range, the grinding amount is kept stable, and the product quality is ensured. The machining precision is ensured, and the problems in the prior art are solved. The present invention is not limited to the embodiments described, but rather, variations, modifications, substitutions and alterations are possible without departing from the spirit and scope of the present invention.
