Description
TECHNICAL FIELD
[0001] The utility model relates to a glass excess amount detection device, specifically a detector for cutting excess amount of glass edging machine. BACKGROUND
[0002] The existing glass edging machine is mainly used for fine cutting and trimming of the edge of glass. In the glass edging machine, in order to ensure that the size of the processed glass meets the installation precision requirement and the edge flatness, an excess amount detection device is usually installed to detect the excess amount of the glass edge in real time so as to facilitate the subsequent installation size or edge grinding chamfering operation. In the conventional technology, the glass excess amount detection device generally adopts a grating ruler advancing and retreating mode for detection. The grating ruler probe is in hard contact with the glass edge, the distance between the glass edge and the reference position is measured, and thus the flatness information of the glass edge is obtained. Although the measurement of the glass edge excess amount can be realized to a certain extent, the hard contact will interfere with the running stability of the glass, causing slight shaking of the glass and affecting the measurement accuracy, resulting in deviation of the detection data and low measurement precision. In order to solve the above-mentioned drawbacks, a soft contact replacing the probe of the grating ruler by using a bump wheel appears on the market. A spring is used inside to reset the bump wheel. The bump wheel can continuously and closely contact the glass edge, but the internal structure is relatively complex. The spring is prone to lose elasticity in the long-term swinging and pulling process, resulting in a decrease in the measurement precision and inability to ensure that the excess amount detection device can work stably for a long time. At the same time, in order to replace the spring that loses elasticity, the user needs to frequently replace or maintain the probe, increasing the operation cost and maintenance complexity of the equipment and being not conducive to popularization and use.

[0021] The present application will be further described in detail below with reference to the drawings. A detector for cutting margin of glass edge grinding machine comprises a mounting seat 1, an encoder 2 connected to the top of the mounting seat 1, and a margin detection assembly 3 connected to the bottom of the mounting seat 1 through a fixing seat 4.
[0022] The excess amount detection assembly 3 comprises a rotating shaft 31, a rotating shaft disc 32 sleeved on the rotating shaft 31, and a plurality of lower magnetic rings 33 distributed around the rotating shaft 31 on the periphery of the rotating shaft disc 32.
[0023] The bottom of the fixed seat 4 is provided with a movable groove 41, and a plurality of upper magnetic rings 42 are fixedly installed in the movable groove 41 and are mutually attracted with the lower magnetic rings 33 to push the rotating shaft 31 to rotate to a set angle.
[0024] The bottom of the rotating shaft 31 is connected with a swing arm 34, and a bump wheel 35 is installed on the free end of the swing arm 34.
[0025] The upper magnetic rings 42 and the lower magnetic rings 33 are permanent magnets with opposite magnetic properties.
[0026] The upper magnetic rings 42 are symmetrically distributed in two groups, and each group of upper magnetic rings 42 is provided with at least three upper magnetic rings 42.
[0027] The lower magnetic rings 33 are provided in two groups and symmetrically distributed at 180° on the periphery of the rotating shaft 31.
[0028] The swing arm 34 is provided with a waist-shaped connecting groove 341, and the bottom of the rotating shaft 31 is inserted into the connecting groove 341.
[0029] Working principle: In the excess amount detector of the glass edge grinding machine, the top of the mounting seat is connected with an encoder, and the bottom is connected with the excess amount detection assembly through the fixed seat.
[0030] The excess amount detection assembly comprises a rotating shaft, the bottom of the rotating shaft is connected with a swing arm, and a bump wheel installed on the free end of the swing arm is in contact with the glass edge, which replaces the traditional grating head hard contact, reduces the interference on the glass transmission stability, ensures the running stability of the glass in the processing process, and improves the detection reliability and processing quality.
[0031] The excess amount detection assembly further comprises a rotating shaft disc sleeved on the rotating shaft, and a plurality of lower magnetic rings distributed around the rotating shaft on the periphery of the rotating shaft disc; corresponding to the lower magnetic rings, a plurality of upper magnetic rings are fixedly installed in the movable groove at the bottom of the fixed seat, the mutual attraction characteristics of the upper magnetic rings and the lower magnetic rings are used to push the rotating shaft to rotate to a set angle, and the rotation angle of the rotating shaft is accurately recorded by the encoder, so as to obtain the glass width data.
[0032] It needs to be explained that the glass to be measured is transported and moved by the edging machine, and the edge thereof is in contact with the impact wheel, which pushes the swing arm to change the angle. Since the free end of the swing arm is connected to the bottom of the rotating shaft through the waist-shaped connecting groove, the change of the angle of the swing arm synchronously drives the rotating shaft to rotate, drives the rotating shaft disc to follow the rotation, and the lower magnetic ring changes the position with the rotation of the rotating shaft disc. The lower magnetic ring and the upper magnetic ring are attracted to each other by opposite magnetism, so that the rotating shaft always keeps balance and stability within a certain range. When the rotating shaft deviates from the set angle, the attraction pushes the rotating shaft back to the stable balance position, ensuring the stability and reliability of the excess detection process.
[0033] The rotating shaft is pushed to rotate by magnetic attraction, which sensitively detects the slight change of the glass edge excess, realizes high-sensitivity detection of the excess detection assembly, has high detection precision, low detection error, ensures the reliability of the detection data, is suitable for the high-speed processing environment of the glass edging machine, ensures that the detection data is detected and adjusted in real time, and improves the processing efficiency and product quality.
[0034] The upper magnetic ring is symmetrically distributed in two groups, and at least three upper magnetic rings are arranged in each group, and adjacent upper magnetic rings in each group are spaced apart. The lower magnetic ring is provided with two 180° symmetrical distribution, which ensures that the excess detection assembly can detect the glass edge in real time and provide more accurate data for the system.
[0035] In addition, since the magnet device is used to generate elastic thrust to push the impact wheel to move in the case, and the rotating thrust is generated in a non-mechanical contact manner, the related moving parts will not be damaged due to aging, so that the device can work stably and efficiently for a long time, and can be widely used.
[0036] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, the present application can also have various changes and improvements, and these changes and improvements all fall within the scope of the claimed present application.
