[0020] Referring to Figure 1 The clamping device for glass transmission of the embodiment comprises a transmission station 1, a connecting roller 2, a sensor 6, a guide mechanism 3, a first clamping mechanism 4, a second clamping mechanism 5 and a control module. One end of the connecting roller 2 is close to one end of the transmission station 1. At the beginning, the glass 7 is located on the transmission station 1, and the glass 7 is conveyed to the connecting roller 2 by the transmission station 1.

The first clamping mechanism 4 is located between the sensor 6 and the second clamping mechanism 5, and the width of the connecting roller 2 is greater than the width of the glass 7.

[0021] Further, the sensor 6 of the embodiment is a photoelectric sensor. Through the processing of the photoelectric signal emitted by the sensor 6 by the control module, the control of the first clamping mechanism 4 and the second clamping mechanism 5 is realized, and the place where the glass 7 starts to be clamped and the clamping time can be individually set by the control module, so that the action is fine and adjustable.

[0022] Further, the first clamping mechanism 4 comprises a first driver 41, a first clamping block 42, a first roller 43 and a first electromagnetic valve, the first electromagnetic valve is fixedly connected with the first driver 41, and the first electromagnetic valve is also electrically connected with the control module for receiving the signal sent by the control module. The shell of the first driver 41 is fixedly connected with one side of the connecting roller way 2, and one end of the telescopic shaft of the first driver 41 is fixedly connected with one side of the first clamping block 42; the bottom surface of the first clamping block 42 is uniformly spaced with a plurality of first rollers 43, and the first driver 41 is used to drive the first clamping block 42 to move back and forth along the width direction of the connecting roller way 2 to approach and / or away from the side edge of the glass 7.

[0023] Further, the second clamping mechanism 5 comprises a second driver 51, a second clamping block 52, a second roller 53, a fixed plate, an adjusting rod 55 and a second electromagnetic valve, the second electromagnetic valve is fixedly connected with the second driver 51, and the second electromagnetic valve is also electrically connected with the control module for receiving the signal sent by the control module. One end of the telescopic shaft of the second driver 51 is fixedly connected with one side of the second clamping block 52, and the bottom surface of the second clamping block 52 is uniformly spaced with a plurality of second rollers 53, and the second driver 51 is used to drive the second clamping block 52 to move back and forth along the width direction of the connecting roller way 2. In addition, the fixed plate comprises a first plate body 541 and a second plate body 542 which are perpendicular to each other, the shell of the second driver 51 is fixedly connected with one side of the first plate body 541, one end of the adjusting rod 55 is connected with one side of the connecting roller way 2 and can rotate relative to one side of the connecting roller way 2 without displacement; the adjusting rod 55 of the embodiment is preferably a lead screw, the other end of the adjusting rod 55 penetrates through the width direction of the second plate body 542, and the adjusting rod 55 is rotationally connected with the second plate body 542 so that the other components of the second clamping mechanism 5 except the adjusting rod 55 can move along the width direction of the connecting roller way 2, thereby changing the distance between the second clamping mechanism 5 and the guide mechanism 3 to adapt to the glass 7 of different widths.

[0024] In addition, the first driver 41 and the second driver 51 of the embodiment are preferably air cylinders, and a throttle valve is installed on each of the first driver 41 and the second driver 51 for adjusting the inlet and outlet valve opening degree, controlling the action speed of the first driver 41 and the second driver 51, further expanding the adjustment space, and ensuring that the glass 7 does not tilt.

[0025] Further, the guide mechanism 3 comprises a connecting plate 31, a plurality of connecting rods 32 arranged at one side of the connecting plate 31, and a plurality of third rollers 33 evenly spaced on the bottom surface of the connecting plate 31, and one end of the plurality of connecting rods 32 away from the connecting plate 31 is fixedly connected with one side of the connecting roller 2. The first roller 43, the second roller 53 and the third roller 33 are located on the same horizontal plane, and the distance between the second roller 53 and the third roller 33 is less than the distance between the first roller 43 and the third roller 33. Specifically, the glass 7 in the embodiment has a first state, a second state and a third state during transmission. When the glass 7 is in the first state, the width of the glass 7 is less than the distance between the first roller 43 and the third roller 33, that is, one side of the glass 7 is in contact with one side of the first roller 43, and the other side of the glass 7 has a gap with the third roller 33; when the glass 7 is in the second state, one side of the glass 7 is in contact with one side of the first roller 43 and one side of the second roller 53, and the other side of the glass 7 has a gap with the third roller 33; when the glass 7 is in the third state, one side of the glass 7 is in contact with one side of the second roller 53, and the other side of the glass 7 is in contact with one side of the third roller 33. When the glass 7 is in the first state, the transmission speed of the transmission table 1 is equal to the transmission speed of the connecting roller 2, which is relatively slow; when the glass 7 is in the second state and / or the third state, the transmission speed of the connecting roller 2 is greater than the transmission speed of the connecting roller 2 when the glass 7 is in the first state, which is relatively fast. By setting different parameters in the control module, the high speed and low speed of the connecting roller 2 can be switched.

[0026] Under the action of the second clamping mechanism 5, the glass 7 is clamped by the second roller 53 and the third roller 33 at the same time for transmission. When the glass 7 is sent from the transmission table 1 to the connecting roller 2 and has not yet reached the first state, the side of the glass 7 close to the first clamping mechanism 4 has a gap with the first roller 43. Under the driving action of the first driver 41, the first clamping block 42 and the first roller 43 are driven to move close to the side of the glass 7 until they are in contact with the side of the glass 7. In this embodiment, the extension stroke of the extension shaft of the first driver 41 and the extension shaft of the second driver 51 is fixed. The glass 7 will move a distance towards the side close to the guide mechanism 3 under the push of the extension shaft of the first driver 41, and will move a distance towards the side close to the guide mechanism 3 under the push of the extension shaft of the second driver 51. In this embodiment, the driving stroke of the first driver 41 and the second driver 51 is set to be half of the distance that the glass 7 needs to move in the width direction of the connecting roller 2 (the sum of the two distances), which can minimize the stroke of a single driver and avoid the clamping distance being too large, so that the inclination of the glass 7 is not too large.

[0027] The working process of the adjusting device of the embodiment is as follows:

[0028] When the glass 7 starts to move on the conveying table 1 and gradually approaches the connecting roller 2, one end of the glass 7 reaches the end of the connecting roller 2 close to the conveying table 1, and when the glass 7 runs to the position of the sensor 6, the sensor 6 sends an optical signal to the control module, so that the control module controls the conveying speed of the connecting roller 2 and switches the speed to the same speed as the conveying table 1, to ensure synchronous operation.

[0029] In the embodiment, according to the parameter position in the control module, when the middle part of the glass 7 reaches the position of the first clamping mechanism 4, the control module controls the first driver 41 to act so that the first clamping block 42 and the first roller 43 extend to the side edge of the glass 7 until contacting the side edge of the glass 7, and push the glass 7 to translate by a distance to the side close to the guide mechanism 3, and at this time, the glass 7 is in the first state. At this time, a part of the glass 7 is still on the conveying table 1, and since the friction forces of the conveying table 1 and the connecting roller 2 on the glass 7 are different, the control module controls the first driver 41 to act slowly, to ensure that the head and tail of the glass 7 do not tilt by a large amplitude.

[0030] When the glass 7 continues to run and reaches the middle part of the connecting roller 2 and the tail of the glass 7 leaves the sensor 6, the control module controls the connecting roller 2 to switch to high-speed operation, and the control module also controls the second driver 51 to act, and at this time, the second driver 51 acts slightly faster, to ensure that the contact position of the second clamping block 52 with the side edge of the glass 7 changes little to quickly push the glass 7 to move to the side close to the guide mechanism 3, to reach the target translation position, and at this time, the glass 7 is in the third state. In the process, when the extension shaft of the second driver 51 extends and contacts the side edge of the glass 7, the glass 7 is in the second state.

[0031] In addition, when the length of the glass 7 to be conveyed changes, the parameters in the control module need to be changed, so that when the glass 7 reaches the middle part of the first clamping mechanism 4 and the second clamping mechanism 5, the respective drivers act. When the width of the glass 7 to be conveyed changes, it needs to be ensured that one side of the glass 7 does not interfere with the first clamping mechanism 4, otherwise the glass 7 cannot pass through. After adjusting the rod 55, the second clamping mechanism 5 cannot exceed the position after the first clamping mechanism 4 acts in the vertical conveying direction, otherwise the glass 7 cannot pass through the second clamping mechanism 5, and cannot be lower than the position before the first clamping mechanism 4 acts, otherwise the second clamping mechanism 5 cannot contact the glass 7 and cannot play a clamping role.

[0032] The above embodiment is only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application should be covered within the protection scope of the present application.
