Detailed implementation

[0014] Refer to Figures 1 - 11 , a visual image transmission device for machine vision, including an image processor 2 and multiple cameras 3. A control board 11 is fixedly connected to the lower side of the image processor 2. The multiple cameras 3 are fixedly installed on the control board 11 through multiple bolts. A transmission assembly is installed on the outside of the control board 11. A cleaning assembly for the cameras 3 is installed on the upper side of the control board 11. The cleaning assembly includes multiple moving rings 9 slidably installed on the upper side of the control board 11. The positions and quantities of the multiple moving rings 9 correspond to those of the cameras 3. A friction cleaning ring 16 is rotatably connected to the inner side of each moving ring 9. A sliding cylinder 24 is fixedly connected to the lower side of each moving ring 9. The sliding cylinder 24 slidably penetrates through the control board 11. A connecting threaded rod 27 is threadedly connected to the lower side of the sliding cylinder 24. A connecting cylinder 28 is fixedly connected to the lower side of the connecting threaded rod 27. A fixing rod 17 is fixedly connected to the lower side of the connecting cylinder 28. A moving plate 13 is fixedly connected to the lower sides of the multiple fixing rods 17 together. A control assembly for controlling the rotation of the friction cleaning ring 16 is installed on the upper side of the control board 11. The control assembly includes a transmission rod 31 fixedly and rotatably penetrating through the sliding cylinder 24. A square rod 14 is fixedly connected to one end of the transmission rod 31. A gear 29 is fixedly connected to the other end of the transmission rod 31. Multiple racks 30 are fixedly connected to the upper side of the control board 11. The positions and quantities of the multiple racks 30 correspond to those of the gear 29, and each rack 30 meshes with the gear 29. A rotating plate 26 is fixedly connected to the outside of the transmission rod 31. A through groove is formed on the outside of the moving ring 9. A moving rod 23 is fixedly connected to the outside of the friction cleaning ring 16. A second spring 32 is fixedly connected between the moving rod 23 and the through groove. A cleaning towel is fixedly connected to the inner side of the friction cleaning ring 16. The cleaning effect on the surface of the camera 3 is formed by using the cleaning towel. And the cleaning towel is sleeved on the outside of the friction cleaning ring 16. The cleaning towel is fixed on the outside of the friction cleaning ring 16 by spring clamping. After a period of time, the cleaning towel can be replaced, so as to maintain the cleaning effect of the friction cleaning ring 16; First, the image processor 2 is electrically connected to all the cameras 3 through wires. When performing machine vision work, the image processor 2 and the cameras 3 are activated. The cameras 3 can transmit the captured data into the image processor 2, and then the obtained data is transmitted to the controller through the image processor 2. The controller analyzes the obtained data and finally transmits the analyzed data to the corresponding staff, thus completing the machine vision work. All the above work is prior art and will not be elaborated further. Before the whole device starts working, rotate the connecting cylinder 28. The connecting cylinder 28 drives the connecting threaded rod 27 to rotate. Since the sliding cylinder 24 and the control board 11 are connected in a vertically sliding manner, the rotating connecting threaded rod 27 will cause the sliding cylinder 24 to move relative to the connecting threaded rod 27, thereby adjusting the actual length between the connecting threaded rod 27 and the sliding cylinder 24, and then completing the adjustment operation of the movement trajectory of the moving ring 9. Then, during the up and down movement of the moving plate 13 (the structure and principle of the up and down movement of the moving plate 13 will be described later), the moving plate 13 drives the sliding cylinder 24 to move up and down through the fixed rod 17, the connecting cylinder 28 and the connecting threaded rod 27. The sliding cylinder 24 drives the moving ring 9 and the friction cleaning ring 16 to move up and down. The friction cleaning ring 16 is located outside the camera 3 and can form a cleaning effect on the surface of the camera 3, so that the camera 3 can always maintain a good working state. Then, during the up and down movement of the sliding cylinder 24, the gear 29 and the rack 30 are always in a meshed state. Since the rack 30 and the control board 11 are fixedly connected, during the up and down movement following the sliding cylinder 24, the gear 29 following the sliding cylinder 24 will rotate. The gear 29 drives the transmission rod 31 and the rotating plate 26 to rotate. There are multiple rotation angles on the outer side of the rotating plate 26. During the rotation of the rotating plate 26, when the rotation angle abuts against the moving rod 23, it will cause the moving rod 23 to rotate relative to the moving ring 9. The moving rod 23 will cause the connected second spring 32 to deform, and the rotating moving rod 23 will drive the friction cleaning ring 16 to rotate. When the rotation angle disconnects from the moving rod 23, under the action of the second spring 32, the moving rod 23 will return to its original position relative to the moving ring 9. As a result, during the rotation of the rotating plate 26, the moving rod 23 and the friction cleaning ring 16 rotate back and forth. The friction cleaning ring 16 abuts against the camera 3, and the rotating back and forth friction cleaning ring 16 can better form a friction cleaning effect on the surface of the camera 3, so that the camera 3 can always be in a good working state; And in the above working process, the rotating transmission rod 31 will always drive the square rod 14 to rotate. In the process of the detected object moving, when the detected object and the square rod 14 are against each other, the detected object stops moving due to the obstruction of the square rod 14, and because the square rod 14 is in a rotating state, the detected object will not be in a stationary state under the obstruction of the square rod 14, that is, the detected object will move accordingly, and then when the camera 3 is used for shooting, the detected object will move itself, which can greatly improve the detection efficiency of the camera 3 and reduce the generation of blind spots in shooting.

[0015] The transmission component includes two fixed plates 5, and a plurality of transmission rods 6 are rotatably connected between the two fixed plates 5. The outer sides of the plurality of transmission rods 6 are fixedly connected with transmission rollers 7, and the outer sides of the plurality of transmission rollers 7 are sleeved with a transmission belt 1. The outer side of one of the fixed plates 5 is fixedly connected with a motor 4, and the outer side of the fixed plate 5 is rotatably connected with a rotating shaft 18. The control plate 11 is fixedly connected to one of the fixed plates 5 through a connecting plate 12, and the outer side of the rotating shaft 18 is fixedly connected with a cam 19. The output shaft of the motor 4 is connected to the rotating shaft 18 through a pulley assembly 8. A plurality of rubber strips are evenly fixedly connected to the outer side of the transmission belt 1 to increase the friction of the transmission belt 1 and reduce the possibility of the transported object falling from the transmission belt 1. First, when the device as a whole needs to be inspected, the object to be inspected is placed on the conveyor belt 1, and the motor 4 is started, and the motor 4 drives the conveyor rod 6 to rotate. Figure 2 From the perspective of , the motor 4 drives the transmission rod 6 to rotate counterclockwise, the transmission rod 6 drives the transmission belt 1 to move through the transmission roller 7, and the transmission belt 1 drives the object to move to the left. At the same time, the output shaft of the motor 4 will also drive the rotating shaft 18 to rotate through the pulley assembly 8, and the rotating shaft 18 drives the cam 19 to rotate. When the cam 19 rotates, the first spring 21 is always in a stretched state, that is, the cam 19 and the moving plate 13 are always in a state of resistance. During the rotation of the cam 19, the moving plate 13 will be caused to move up and down all the time.

[0016] A cleaning assembly is installed on the outer side of the slide 24, and the cleaning assembly includes a connecting rod 25 fixedly installed on the side wall of the slide 24, a cleaning box 10 is fixedly connected to the outer side of the connecting rod 25, a square plate 34 is slidably connected to the lower side of the cleaning box 10, a cleaning plate 15 is fixedly connected to the lower side of the square plate 34, a third spring 33 is fixedly connected between the square plate 34 and the cleaning box 10, a round rod 35 is fixedly connected to the outer side of the square plate 34, and the side walls of the round rod 35 and the rotating plate 26 are all smooth, so as to reduce the friction between the round rod 35 and the rotating plate 26, so as to better perform the corresponding transmission; During the up and down movement of the sliding cylinder 24, the sliding cylinder 24 drives the cleaning box 10 to move up and down through the connecting rod 25. The cleaning box 10 that moves up and down drives the square plate 34 and the cleaning plate 15 to move up and down. Since the end of the round rod 35 is provided with an arc, during the up and down movement of the square plate 34 following the cleaning box 10, when the round rod 35 abuts against the rotating rotating plate 26, under the extrusion of the rotating plate 26, Figure 11 from the perspective of

[0017] Figure 11 , the square plate 34 and the round rod 35 as a whole will move leftward relative to the cleaning box 10. While compressing the third spring 33, the square plate 34 will drive the fixedly connected cleaning plate 15 to move. When the round rod 35 disconnects from the rotating plate 26, under the action of the third spring 33, the square rod 14 and the round rod 35 return to their original positions relative to the cleaning box 10. As a result, during this process, the square plate 34 and the cleaning plate 15 keep moving back and forth. When the object to be detected moves to the lower side of the cleaning plate 15, since the lower side of the cleaning plate 15 is provided with a brush plate, the brush plate that moves back and forth following the cleaning plate 15 can form a cleaning effect on the object, maintaining the cleanliness of the object to be detected, and thus improving the accuracy of the shooting effect of the camera 3.In the present invention, before the whole device operates, the connecting cylinder 28 is rotated. The connecting cylinder 28 drives the connecting threaded rod 27 to rotate. Since the sliding cylinder 24 and the control board 11 are connected in a vertically sliding manner, the rotating connecting threaded rod 27 will cause the sliding cylinder 24 to move relative to the connecting threaded rod 27, thereby adjusting the actual length between the connecting threaded rod 27 and the sliding cylinder 24, and then completing the adjustment operation of the movement trajectory of the moving ring 9. Then, during the up-and-down movement of the moving plate 13 (the structure and principle of the up-and-down movement of the moving plate 13 will be described later), the moving plate 13 drives the sliding cylinder 24 to move up and down through the fixed rod 17, the connecting cylinder 28 and the connecting threaded rod 27. The sliding cylinder 24 drives the moving ring 9 and the friction cleaning ring 16 to move up and down. The friction cleaning ring 16 is located outside the camera 3 and can form a cleaning effect on the surface of the camera 3, so that the camera 3 can always maintain a good working state. Then, during the up-and-down movement of the sliding cylinder 24, the gear 29 and the rack 30 are always in a meshed state. Since the rack 30 and the control board 11 are fixedly connected, during the up-and-down movement following the sliding cylinder 24, the gear 29 following the sliding cylinder 24 will rotate. The gear 29 drives the transmission rod 31 and the rotating plate 26 to rotate. There are multiple rotation angles on the outside of the rotating plate 26. During the rotation of the rotating plate 26, when the rotation angle abuts against the moving rod 23, it will cause the moving rod 23 to rotate relative to the moving ring 9. The moving rod 23 will cause the connected second spring 32 to deform, and the rotating moving rod 23 will drive the friction cleaning ring 16 to rotate. When the rotation angle disconnects from the moving rod 23, under the action of the second spring 32, the moving rod 23 will return to its original position relative to the moving ring 9. As a result, during the rotation of the rotating plate 26, the moving rod 23 and the friction cleaning ring 16 rotate back and forth. The friction cleaning ring 16 abuts against the camera 3, and the rotating back-and-forth friction cleaning ring 16 can better form a friction cleaning effect on the surface of the camera 3, so that the camera 3 can always be in a good working state; And during the above working process, the rotating transmission rod 31 will always drive the square rod 14 to rotate. During the movement of the object to be detected, when the object to be detected abuts against the square rod 14, under the blocking action of the square rod 14, the object to be detected stops moving. And since the square rod 14 is in a rotating state, under the blocking action of the square rod 14, the object to be detected will not be in a stationary state, that is, the object to be detected will move accordingly. As a result, when using the camera 3 for shooting, the object to be detected itself will also move, which can greatly improve the detection efficiency of the camera 3 and reduce the generation of shooting dead angles; When the whole device needs to be detected, place the object to be detected on the conveyor belt 1, start the motor 4, and the motor 4 drives the transmission rod 6 to rotate, so as to Figure 2From the perspective of [description missing], the motor 4 drives the transmission rod 6 to rotate counterclockwise. The transmission rod 6 drives the transmission belt 1 to move through the transmission roller 7, and the transmission belt 1 drives the object to move to the left. At the same time, the output shaft of the motor 4 also drives the rotating shaft 18 to rotate through the pulley assembly 8, and the rotating shaft 18 drives the cam 19 to rotate. When the cam 19 rotates, the first spring 21 is always in a stretched state, that is, the cam 19 and the moving plate 13 are always in contact. During the rotation of the cam 19, the moving plate 13 will always move up and down; During the up and down movement of the sliding cylinder 24, the sliding cylinder 24 drives the cleaning box 10 to move up and down through the connecting rod 25. The cleaning box 10 that moves up and down drives the square plate 34 and the cleaning plate 15 to move up and down. Since the end of the round rod 35 is arc-shaped, during the up and down movement of the square plate 34 following the cleaning box 10, when the round rod 35 abuts against the rotating rotating plate 26, under the extrusion of the rotating plate 26, Figure 11 From the perspective of [description missing], the square plate 34 and the round rod 35 as a whole will move leftward relative to the cleaning box 10. While compressing the third spring 33, the square plate 34 will drive the fixedly connected cleaning plate 15 to move. When the round rod 35 disconnects from the rotating plate 26, under the action of the third spring 33, the square rod 14 and the round rod 35 return to their original positions relative to the cleaning box 10. As a result, during this process, the square plate 34 and the cleaning plate 15 will always move back and forth. When the object to be detected moves to the lower side of the cleaning plate 15, since the lower side of the cleaning plate 15 is equipped with a brush plate, the brush plate that moves back and forth following the cleaning plate 15 can form a cleaning effect on the object, maintaining the cleanliness of the object to be detected, and thus improving the accuracy of the shooting effect of the camera 3.
