Description

Technical Field

[0001] The utility model relates to a structural improvement of a glass length and width detection mechanism. Background Art

[0002] Before or after glass processing, length and width detection is required to provide a basis for setting processing parameters in subsequent processes or to confirm whether the size of the processed glass meets the requirements. Traditional technology often uses a reading head to read the data on the grating ruler to measure the length or width of the glass. The grating ruler is easily disturbed by clutter in a complex environment, affecting the accuracy of the measurement. Utility Model Content

[0003] The utility model aims to provide a glass length and width detection mechanism which is not easily affected by the environment.

[0004] The utility model adopts the following technical solutions:

[0005] The glass length and width detection mechanism includes a crossbeam, a slide rail and a rack are horizontally arranged on the same side of the crossbeam, the rack is located below the slide rail and the teeth are arranged on its bottom surface, a slide plate is arranged on the crossbeam, the slide plate is slidably connected to the slide rail through a slider arranged on the back side of the slide plate, a servo motor with an encoder and a goniometer is fixedly installed on the front side of the slide plate, the output shaft of the servo motor moves through the slide plate and then transmits a gear meshing with the rack, a vertical pole is also arranged on the slide plate, the top of the vertical pole is arranged with an ultrasonic switch.

[0006] As a preferred solution, the slide plate is longitudinally provided with an adjusting long hole, the slide block behind the adjusting long hole is correspondingly provided with a screw hole, and a bolt for locking the slide plate to the slide block is provided between the adjusting long hole and the screw hole.

[0007] The utility model measures the length or width of the glass by combining a servo motor with an encoder and a goniometer with an ultrasonic switch. The measuring process is not easily disturbed by the external environment, which is conducive to improving the accuracy of the measurement. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is described below in conjunction with the accompanying drawings and specific embodiments.

[0012] Reference Figure 1-3 :

[0013] The glass length and width detection mechanism comprises a crossbeam 1, a slide rail 2 and a rack 3 are disposed on the same side of the crossbeam 1, the rack 3 is located below the slide rail 2 and has teeth disposed on its bottom surface.

[0014] A slide plate 4 is provided on the cross beam 1 , and a servo motor 5 with an encoder and an angle encoder is fixedly installed on the front of the slide plate 4 . The output shaft of the servo motor 5 movably passes through the slide plate 4 and then drives a gear 6 meshing with the rack 3 .

[0015] The slide plate 4 is slidably connected to the slide rail 2 through the slider 7 provided on the back thereof. The slide plate 4 is longitudinally provided with an adjustment slot 4.1, and the slider 7 behind the adjustment slot 4.1 is provided with a corresponding screw hole, and a bolt is provided between the adjustment slot 4.1 and the screw hole to lock the slide plate 4 on the slider 7. By connecting the screw to different positions of the adjustment slot 4.1, the height of the slide plate 4 on the slider 7 can be adjusted, and then the tightness of the engagement between the gear 6 and the rack 3 can be adjusted.

[0016] The slide plate 4 is also provided with a vertical rod 8 whose top is higher than the top of the cross beam 1 and the slide plate 4 , and an ultrasonic switch 9 is provided at the top of the vertical rod 8 .

[0017] When used to measure the length of glass, the crossbeam 1 is set parallel to the outside of the long side of the glass 10, the servo motor 5 drives the gear 6 to rotate, the gear 6 drives the slide plate 4 to slide along the slide rail 2, the slide plate 4 drives the servo motor 5 and the ultrasonic switch 9 to move back and forth, the ultrasonic switch 9 senses the starting end and the end end of the glass 10, the goniometer and encoder in the servo motor 5 are used to convert the unidirectional stroke speed of the servo motor 5 into a linear value, so as to realize the measurement of the length of the glass 10.

[0018] When used to measure the width of glass, the beam 1 is set parallel to the outside of the wide side of the glass, and the measuring process is the same as the aforementioned process of measuring the long side.
