DETAILED DESCRIPTION

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 3 As shown, a glass substrate visual detection sensor 100 of the present invention includes a fixing base 1 , a sensing element 2 and a sensor 3 .

[0021] The fixing base 1 is provided with a mounting groove 11 in the middle, and symmetrically designed "L"-shaped mounting plates 12 on both sides. The mounting plate 12 of the fixing base 1 is provided with an elongated bolt hole 121, and a first bolt 13 passes through the bolt hole 121 to mount the fixing base 1 on the glass substrate conveying mechanism. The fixing base 1 can be conveniently adjusted in height by providing the elongated bolt hole 121; a contact wheel 21 is provided on the top of the sensing element 2 and protrudes from the top of the fixing base 1; the sensing element 2 is swingably provided in the mounting groove 11 of the fixing base 1 by a fixing pin 22, and the fixing pin 22 can make the sensing element swing back and forth on the fixing base 1; two gaskets 23 are sleeved on the fixing pin 22, and the two gaskets 23 are respectively located on both sides of the sensing element 2 to isolate the sensing element 2 from the fixing base 1. By providing the gasket 23, the magnetic induction abnormality caused by the left and right movement of the sensing element 2 during the swinging process can be avoided. The sensor 3 includes a housing 31, a magnetic switch 32, a resistor chip 33 and an indicator light 34. The magnetic switch 32, the resistor chip 33 and the indicator light 34 are all arranged in the housing 31; the housing 31 is fixed to the lower part of the mounting slot 11 of the fixing base 1 and is located directly below the sensing element 2. One end of the housing 31 is fixed to the fixing base 1 by a second bolt 311; the magnetic switch 32 and the resistor chip 33 are respectively connected to the indicator light 34, which is an LED indicator light. The sensor 3 is connected to an external power supply via wires.

[0022] During use, a detection sensor 100 is provided on the conveyor mechanism to confirm the position of the glass substrate 200 and prevent the glass substrate 200 from colliding during conveyance. When installed, the highest point of the contact wheel 21 protrudes from the highest point of the conveyor mechanism's conveyor wheels. Under normal conditions, when the glass substrate 200 does not pass over the detection sensor 100, the sensing element 2 is located above the sensor 3, the magnetic switch 32 senses magnetic force, the control circuit is closed, and the indicator light 34 is illuminated. When the glass substrate 200 passes over the detection sensor 100, the lower surface of the glass substrate 200 presses against the contact wheel 21, tilting the sensing element 2 and moving it away from the sensor 3. The magnetic switch 32 senses the disappearance of the magnetic force, the control circuit is disconnected, and the indicator light 34 is off. Simultaneously, a light on the control panel illuminates, indicating that a glass substrate has passed over the detection sensor.

[0023] The advantages of the present invention are as follows: a swingable and visual detection sensor is provided on the glass substrate conveying mechanism to confirm the position of the glass substrate and prevent the glass substrate from colliding during the conveying process; an indicator light is provided on the sensor to facilitate timely detection of detection sensor failure during inspection and timely replacement of the detection sensor, thereby reducing downtime; and the replacement personnel can directly determine whether the component has been replaced based on whether the indicator light is on / off, making replacement simple and convenient and saving manpower.
