Technical Field

[0001] This utility model relates to the field of transmission and detection technology, and in particular to a detection device for the range of a semi-grid glass arrangement. Background Technology

[0002] In the production process of tempered glass, the production of semi-gated glass has certain length limitations. The glass needs to be placed precisely within a specified range during transportation. However, the length of the glass needs to be measured manually. Manual measurement has a large error and low efficiency, which will greatly extend the working time. If the measurement error is large, the quality of the produced glass will be unreliable and it is very likely to break. This will reduce production output and increase costs.

[0003] Therefore, this application proposes a detection and control device for the placement range of semi-grate glass on the glass tempering furnace plate stage; its purpose is to assist manual judgment of glass length and ensure that the glass is within the qualified range during the two-station operation of the semi-grate, so as to reduce manual measurement errors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A detection device for the range of semi-grid placed glass includes a roller conveyor for conveying glass and a first through-beam photoelectric sensor disposed at the input end of the roller conveyor. A rotary encoder for detecting the rotational displacement of a drive motor is disposed on the surface of a transmission box in the middle of the roller conveyor. Two sets of straightening components and correction components for correcting tilted glass are symmetrically disposed at the input end of the roller conveyor. Both sets of straightening components are located in front of the first through-beam photoelectric sensor, and the correction components are located between the first through-beam photoelectric sensor and the straightening components.

[0006] In some embodiments, the straightening assembly includes a straightening frame for pushing the glass to move and two guide rods for sliding the straightening frame on a fixed frame surface. Both guide rods slide on the fixed frame surface, and the sliding direction of the guide rods is perpendicular to the conveying direction of the roller conveyor. The straightening frame is disposed at one end of the two guide rods facing the roller conveyor.

[0007] In some embodiments, the straightening frame includes a fixed plate and a plurality of elastic push plates fixed to the surface of the fixed plate, wherein springs are fixed to the side of the plurality of elastic push plates facing the fixed plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 A detection device for the range of semi-grid glass placement includes a roller conveyor 1 for conveying glass 10 and a first through-beam photoelectric sensor 3 disposed at the input end of the roller conveyor. A transmission box 101 is disposed in the middle of the roller conveyor 1, and a drive motor is disposed inside the transmission box 101. The roller conveyor 1 is prior art and will not be described in detail. A rotary encoder 2 is disposed at the output end of the drive motor and is fixed on the surface of the transmission box 101. A third through-beam photoelectric sensor 7 is fixed on the surface of the roller conveyor 1 and is located behind the first through-beam photoelectric sensor 3. A buzzer 8 is fixed on the surface of the transmission box 101 and a furnace inlet switch 9 is fixed on the surface of the roller conveyor 1. Two sets of straightening components 4 and straightening components 5 are symmetrically arranged at the input end of the roller conveyor device 1 for straightening the tilted glass 10. Both sets of straightening components 4 are located at the front end of the first through-beam photoelectric sensor 3, and the straightening components 5 are located between the first through-beam photoelectric sensor 3 and the straightening components 4.

[0026] It is understandable that by setting a first photoelectric sensor 3 at the input end of the roller conveyor 1 and a rotary encoder 2 at the output shaft of the drive motor, when the roller conveyor 1 conveys the glass 10 past the first photoelectric sensor 3, the rotary encoder 2 simultaneously measures the moving length of the glass 10, thereby detecting the length of the glass 10. When the glass 10 moves to the specified range, the buzzer 8 sounds a prompt, and the roller conveyor 1 conveys the glass 10 into the heating furnace. By setting a third photoelectric sensor 7, the position of the glass 10 is further confirmed to avoid errors.

[0027] Specifically, the straightening assembly 4 includes a straightening frame 404 for pushing the glass 10 to move and two guide rods 402 for sliding the straightening frame 404 on the surface of the fixed frame 401. The fixed frame 401 is fixed to the surface of the roller conveyor 1, and both guide rods 402 slide on the surface of the fixed frame 401. The sliding direction of the guide rods 402 is perpendicular to the conveying direction of the roller conveyor 1. The straightening frame 404 is located at one end of the two guide rods 402 facing the roller conveyor 1. An electric push rod 407 for driving the straightening frame 404 to slide back and forth is fixed on the surface of the fixed frame 401. The straightening frame 404 slides on the surface of the connecting plate 403 via the slider 405. The connecting plate 403 is fixed to one end of the two guide rods 402 facing the roller conveyor 1. One end of the output shaft of the electric push rod 407 is fixed to the surface of the connecting plate 403. A tension spring 406 is provided above the straightening frame 404 and the connecting plate 403 to drive the straightening frame 404 to reset. The two ends of the tension spring 406 are fixed to the surfaces of the straightening frame 404 and the connecting plate 403, respectively. The straightening frame 404 includes a fixed plate 4041 and a plurality of elastic push plates 4042 fixed to the surface of the fixed plate 4041. A spring 4043 is fixed to the side of the plurality of elastic push plates 4042 facing the fixed plate 4041. A slider 405 is fixed to the side of the fixed plate 4041 facing the connecting plate 403 and slides on the surface of the connecting plate 403.

[0028] Understandably, since the initial state of the glass 10 on the surface of the roller conveyor 1 may be inclined, when the inclined glass 10 passes the first photoelectric sensor 3, it first detects one corner of the glass 10, causing the rotary encoder 2 to start detecting the position of the glass 10 in advance, resulting in a deviation in the placement range of the glass 10. Therefore, a straightening component 4 is set up. The electric push rod 407 drives the connecting plate 403 and the guide rod 402 to slide on the surface of the fixed frame 401, causing the straightening frame 404 to move towards the glass 10. When multiple elastic push plates 4042 abut against the surface of the glass 10, the generated thrust drives the glass 10 to move, thus correcting its position. This is achieved by setting elastic push plates 4042 and springs 4042. 43, thus making elastic contact when in contact with glass 10, thereby protecting glass 10. By driving the straightening frame 404 to slide back and forth, glass 10 is pushed multiple times to correct it. By setting slider 405 and connecting plate 403, when elastic push plate 4042 contacts glass 10, since glass 10 is still moving, glass 10 drives elastic push plate 4042 and fixing plate 4041 to slide on the surface of connecting plate 403 through slider 405, making them relatively stationary, avoiding friction between glass 10 and elastic push rod. When the straightening frame 404 moves away from glass 10, the tension spring 406 drives fixing plate 4041 to slide and reset on the surface of connecting plate 403.

[0029] Specifically, the correction component 5 includes a base plate 501 fixed to the surface of the roller conveyor 1 and a slide 502 sliding on the upper surface of the base plate 501. A guide component 503 is provided at one end of the slide 502 near the roller conveyor 1. A locking bolt 504 for fixing the slide 502 is threadedly connected to the surface of the slide 502. A scale line 505 is provided on the surface of the base plate 501. The guide assembly 503 includes multiple rotating wheels 5031 that rotate on the lower surface of the carriage 502. The multiple rotating wheels 5031 are all connected by a guide belt 5032. The surface of the guide belt 5032 is provided with a parallel section for further straightening of the glass 10 and a transition section for facilitating the glass 10 to enter the parallel section. A tension wheel 5033 rotates on the lower surface of the carriage 502. The tension wheel 5033 is used to make the guide belt 5032 and the multiple rotating wheels 5031 fit tightly together. A drive motor is fixed on the upper surface of the carriage 502. One of the rotating wheels 5031 is connected to one end of the output shaft of the drive motor.

[0030] Understandably, since the straightening frame 404 and the glass 10 are in elastic contact, slight deviations may easily occur in the correction of the glass 10. Therefore, a correction component 5 is set to further correct the glass 10. By setting a guide component 503, the drive motor drives the rotating wheel 5031 to rotate, causing the guide belt 5032 to roll. When the glass 10 passes through the transition section, the guide belt 5032 moves and smoothly brings the glass 10 into the parallel section, allowing the glass 10 to move within the parallel section, thereby further correcting the glass 10. The slide 502 slides on the surface of the base plate 501, which facilitates the adjustment of the position of the guide component 503, thereby adjusting the distance between the two sets of guide components 503 to match the width of the glass 10. The locking bolt 504 is set to facilitate the fixation of the slide 502, and the scale line 505 is set to facilitate the observation of the position of the slide 502.

[0031] Specifically, a second photoelectric sensor 6 is fixed on the surface of the roller conveyor 1, and the second photoelectric sensor 6 is located in front of the straightening component 4.

[0032] Understandably, when the glass 10 passes the second photoelectric sensor 6, the straightening component 4 and the correction component 5 start to work when a signal is emitted.

[0033] In this invention, the glass 10 is conveyed by the roller conveyor 1. When the glass 10 passes the second photoelectric sensor 6, a signal is emitted, and the straightening component 4 and the correction component 5 begin to work. The electric push rod 407 drives the connecting plate 403 and the guide rod 402 to slide on the surface of the fixed frame 401, causing the straightening frame 404 to move towards the glass 10. When multiple elastic push plates 4042 abut against the surface of the glass 10, the generated thrust drives the glass 10 to move and perform position correction. By driving the straightening frame 404 to slide back and forth, the glass 10 is pushed multiple times to correct its position. Under the action of the slider 405 and the connecting plate 403, the glass 10 drives the elastic push plates 4042 and the fixed plate 4041 to slide on the surface of the connecting plate 403 through the slider 405, keeping them relatively stationary and avoiding friction between the glass 10 and the elastic push rod. When the straightening frame 404 moves away from the glass 10, the tension spring 406 drives the fixed plate 4041 to move. The fixed plate 4041 slides and resets on the surface of the connecting plate 403, performing initial correction on the glass 10. When the glass 10 passes through the transition section of the guide belt 5032, the guide belt 5032 moves and smoothly brings the glass 10 into the parallel section, allowing the glass 10 to move within the parallel section, thereby further correcting the glass 10. When the roller conveyor 1 transports the glass 10 past the first photoelectric sensor 3, the rotary encoder 2 simultaneously measures the moving length of the glass 10, thus detecting the length of the glass 10. When the glass 10 moves to the designated range, the buzzer 8 sounds a prompt, and the roller conveyor 1 transports the glass 10 into the heating furnace. By setting the third photoelectric sensor 7, the position of the glass 10 is further confirmed to avoid errors, thereby assisting manual judgment of the length of the glass 10 and ensuring that the glass 10 is within the qualified range during the two-station operation of the semi-grid, reducing manual measurement errors.
