DETAILED DESCRIPTION

[0025] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0026] See also Figures 1 to 8 As shown, a double-sided illumination adjustable detection device of the present invention includes an equipment body 1; the equipment body 1 includes a carrier 3, a visual detection device 4, a conveying device 5 arranged on the carrier 3, and a visual driving device 6, the visual driving device 6 is used to drive the visual detection device 4 to move, the conveying device 5 includes a rotatable rotating shaft 501, and a first driving module 502 for driving the rotating shaft 501, the rotating shaft 501 is used to carry materials and drive the materials to move, the visual detection device 4 includes a first detection device 401 and a second detection device 402, the first detection device 401 and the second detection device 402 are respectively used to take photos or videos of different sides of the material to distinguish qualified materials from unqualified materials.

[0027] In this embodiment, the conveyor device 5 is equipped with a material sensor 709, which senses the material. When the material sensor 709 senses the material, the device assumes that the material has reached the inspection zone. The material sensor 709 then sends a signal to trigger the first drive module 502 to stop the rotating shaft 501 or to trigger the stop assembly 510 to stop the material. The first drive module 502 drives the rotating shaft 501, causing the material to move along the supporting surface of the rotating shaft 501 in a predetermined direction and speed. This conveying method ensures that the material passes through the inspection zone in a stable manner, providing optimal conditions for subsequent visual inspection. The visual drive device 6 is responsible for controlling the position and movement of the visual inspection device 4. When the material enters the inspection zone, the visual drive device 6 moves the first and second inspection devices 401, 402 to the appropriate positions according to preset procedures and parameters. These positions are determined based on factors such as the material's size and shape, as well as the key inspection area. The first inspection device 401 is positioned above the material and captures the front of the material, while the second inspection device 402 is positioned below the material and captures the back of the material.

[0028] During actual use, the first drive module 502 drives the rotating shaft 501 to rotate, so that the material carried on the rotating shaft 501 moves in the set direction. When the material moves to the detection area, the material sensor 709 senses the material and sends a stop signal to the first drive module 502. The first drive module 502 stops driving the rotating shaft 501, so that the material stops within the detection area. The visual drive device 6 drives the first detection device 401 to move directly above the material, and the visual drive device 6 drives the second detection device 402 to move directly below the material. The first detection device 401 and the second detection device 402 respectively take pictures or videos of the front and back of the material and transmit the picture data to the data processing center for analysis to distinguish qualified materials from unqualified materials. After the inspection is completed, the inspected materials are transported out of the inspection area and the uninspected materials are transported to the inspection area, and the above steps are repeated.

[0029] Compared with the traditional single-sided illumination detection device, which first photographs the front side of the inspection material and then confirms that it is qualified, the material is turned over with the back side facing up and photographed again. The utility model can reduce the number of material turning steps by setting up a double-sided illumination detection device, which has the advantage of improving efficiency and saving the cost of the turning mechanism.

[0030] Specifically, the visual inspection device 4 also includes an adjusting device 403, which includes a first slide rail 404, a first slider 405 slidingly arranged on the first slide rail 404, and a third drive motor 406 that drives the first slider 405 to move back and forth. The first inspection device 401 and the second inspection device 402 are arranged on the first slider 405, and the adjusting device 403 is used to adjust the distance between the first inspection device 401 and the material and / or the second inspection device 402 and the material.

[0031] In this embodiment, the first detection device 401 and the second detection device 402 can adapt to shooting materials of different sizes. When the detection device needs to be replaced to shoot materials of different sizes, the adjustment device 403 drives the first detection device 401 and / or the second detection device 402 to move closer to or away from the material to achieve a better shooting distance, so that the first detection device 401 and / or the second detection device 402 can capture a clearer image. In actual use, the third drive motor 406 drives the first slider 405 to slide, so that the first detection device 401 and / or the second detection device 402 set on the first slider 405 move closer to or away from the material. By setting the adjustment device 403, the working distance of the first detection device 401 and the second detection device 402 can be automatically adjusted to adapt to different materials and effectively improve production efficiency.

[0032] Specifically, the visual driving device 6 includes a first driving device 601 and a second driving device 602. The first driving device 601 is used to drive the first detection device 401 to move, and the second driving device 602 is used to drive the second detection device 402 to move. The structure of the first driving device 601 is the same as that of the second driving device 602.

[0033] In this embodiment, the first drive device 601 and the second drive device 602 respectively drive the first detection device 401 and the second detection device 402 to move, so that the first detection device 401 and the second detection device 402 can detect different detection surfaces of the same or / and different materials. For example, when the conveying device 5 transports a loading tray carrying multiple materials, the first detection device 401 and the second detection device 402 can photograph or videotape the materials on the loading tray. The technician can set the shooting detection map of the first detection device 401 and the second detection device 402 through the human-computer interaction device 201 (the human-computer interaction device 201 includes: an industrial computer, a display screen, a keyboard and a mouse) according to the discharge order of the materials on the loading tray. The first drive device 601 and the second drive device 602 drive the first detection device 401 and the second detection device 402 to move according to the corresponding map sequence position and shoot and detect the corresponding materials.

[0034] In actual use, when the material sensor 709 senses that the material has reached the detection area, the first drive module 502 stops driving the rotating shaft 501. The first drive device 601 drives the first detection device 401 to move directly above the material, and the second drive device 602 drives the second detection device 402 to move directly below the material. The first detection device 401 and the second detection device 402 respectively photograph or videotape the front and back of the material and analyze whether it passes the test.

[0035] Specifically, the first drive device 601 and the second drive device 602 both include a Y-axis drive module 603 arranged on the carrier 3 and an X-axis drive module 604 arranged on the Y-axis drive module 603. The Y-axis drive module 603 drives the X-axis drive module 604 to move back and forth. The first detection device 401 and the second detection device 402 are respectively arranged on the X-axis drive module 604 of the first drive device 601 and the second drive device 602. The X-axis drive module 604 drives the first detection device 401 and the second detection device 402 to move back and forth. The X-axis drive module 604 and the Y-axis drive module 603 are screw modules. The screw modules include a screw shaft 605, a movable nut 606 movably arranged on the screw shaft 605, and a first drive motor 607 that drives the screw shaft 605 to rotate. The rotation of the screw shaft 605 causes the movable nut 606 to move along the screw shaft 605.

[0036] In this embodiment, the X-axis driving module 604 is disposed on the movable nut 606 of the Y-axis driving module 603 , and the first detection device 401 and the second detection device 402 are disposed on the movable nut 606 of the X-axis driving module 604 .

[0037] In actual use, in the first drive device 601, the first detection device 401 is viewed from the front. The first drive motor 607 of the Y-axis drive module 603 drives the screw shaft 605 to rotate, so that the movable nut 606 drives the X-axis drive module 604 and the first detection device 401 to move forward or backward; the first drive motor 607 of the X-axis drive module 604 drives the screw shaft 605 to rotate, so that the movable nut 606 drives the first detection device 401 to move left or right. In the second drive device 602, the second detection device 402 is viewed from the front. The first drive motor 607 of the Y-axis drive module 603 drives the screw shaft 605 to rotate, so that the movable nut 606 drives the X-axis drive module 604 and the second detection device 402 to move forward or backward; the first drive motor 607 of the X-axis drive module 604 drives the screw shaft 605 to rotate, so that the movable nut 606 drives the second detection device 402 to move left or right. By setting the X-axis driving module 604 and the Y-axis driving module 603 as screw modules, the first detection device 401 and the second detection device 402 can be moved in multiple directions, which is beneficial for the first detection device 401 and the second detection device 402 to move toward the material, thereby improving the detection efficiency.

[0038] Specifically, the first drive module 502 includes a driving sprocket 503, a driven sprocket 504, a chain 505 meshingly connected to the driving sprocket 503 and the driven sprocket 504, and a second drive motor 506 that drives the driving sprocket 503 to rotate. One end of the rotating shaft 501 is set on the sprocket. The second drive motor 506 drives the driving sprocket 503 to rotate and drives the driven sprocket 504 to rotate, so that the rotating shaft 501 set on the driving sprocket 503 and the driven sprocket 504 rotates.

[0039] In this embodiment, there are multiple driven sprockets 504 and chains 505. The driving sprocket 503 and the driven sprocket 504 are double-row sprockets with the same structure. The driving sprocket 503 and the driven sprocket 504 or / and any two adjacent driven sprockets 504 are connected by the chain 505. The driving sprocket 503 and the driven sprocket 504 are both coaxially arranged with the rotating shaft 501.

[0040] In actual use, the second drive motor 506 drives the driving sprocket 503 to rotate, and the driving sprocket 503 drives multiple driven sprockets 504 to rotate, so that the rotating shaft 501 set on the driving sprocket 503 and the driven sprocket 504 rotates, thereby causing the material set on the rotating shaft 501 to move along the set direction.

[0041] Specifically, the conveying device 5 also includes a first conveying substrate 507, a second conveying substrate 508 arranged opposite to the first conveying substrate 507, and a second driving module 509 that drives the first conveying substrate 507 to move back and forth. The rotating shaft 501 is arranged on the first conveying substrate 507 and the second conveying substrate 508. The rotating shaft 501 arranged on the first conveying substrate 507 and the second conveying substrate 508 carries the two ends of the material away from each other. The second driving module 509 drives the first conveying substrate 507 away from or close to the second conveying substrate 508 so that the distance between the first conveying substrate 507 and the second conveying substrate 508 can adapt to materials of different sizes.

[0042] In this embodiment, the second drive module 509 includes a second slide rail 701 disposed on the carrier 3, a second slider 702 slidably disposed on the second slide rail 701, a rotating screw 703, a movable nut 704 movably disposed on the rotating screw 703, and a fourth drive motor 705 for driving the rotating screw 703. The first conveying base 507 is disposed on the second slider 702, and the movable nut 704 is detachably mounted and fixed to the first conveying base 507. When the fourth drive motor 705 drives the rotating screw 703 to rotate, the movable nut 704 moves along the rotating screw 703, causing the first conveying base 507 to drive the first slider 405 to slide along the second slide rail 701.

[0043] In actual use, the fourth drive motor 705 drives the rotating screw 703 to rotate, causing the movable nut 704 to drive the first conveying substrate 507 to slide along the second slide rail 701, and the first conveying substrate 507 moves closer to or away from the second conveying substrate 508. When the conveying device 5 is switched to produce smaller-sized materials, technicians can control the fourth drive motor 705 through the human-machine interface device 201, causing the fourth drive motor 705 to indirectly drive the first conveying substrate 507 closer to the second conveying substrate 508, so that the distance between the first conveying substrate 507 and the second conveying substrate 508 can accommodate smaller-sized materials. When the conveying device 5 is switched to produce larger-sized materials, technicians can control the fourth drive motor 705 through the human-machine interface device 201, causing the fourth drive motor 705 to indirectly drive the first conveying substrate 507 away from the second conveying substrate 508, so that the distance between the first conveying substrate 507 and the second conveying substrate 508 can accommodate larger-sized materials. By providing the second driving module 509 , the distance between the first conveying substrate 507 and the second conveying substrate 508 can be conveniently adjusted, thereby reducing the difficulty of manual operation and effectively improving production efficiency.

[0044] Specifically, the first detection device 401 and the second detection device 402 both include a detection base, an industrial camera 408, an industrial lens 409 and a light source 410 arranged on the detection base. The industrial lens 409 is located between the industrial camera 408 and the light source 410. The industrial camera 408, the industrial lens 409 and the light source 410 are coaxially arranged.

[0045] In this embodiment, the primary function of industrial camera 408 is to capture high-quality images and output the captured image data as a standard digital signal for subsequent system processing. Industrial lens 409 assists the camera in image acquisition. Industrial lens 409 can adjust its focal length to accommodate varying working distances and object sizes, and can also correct for aberrations. Light source 410 provides sufficient light for industrial camera 408, ensuring clear images.

[0046] During actual use, technicians can first establish an ideal image template through the human-computer interaction device 201, and compare the feature similarity between the image taken by the actual industrial camera 408 and the ideal image template. If the similarity is 85% or above (which can be adjusted according to the requirements of different products), it is classified as qualified, otherwise it is classified as unqualified.

[0047] Specifically, the conveying device 5 also includes a stopping assembly 510, which includes a stopping member 511 and a driving cylinder 512 that drives the stopping member 511 to move back and forth. The driving cylinder 512 drives the stopping member 511 to move to the bearing surface of the rotating shaft 501, and the stopping member 511 is used to stop the movement of materials.

[0048] In this embodiment, the stopping assembly 510 is arranged on the first conveying substrate 507 and / or the second conveying substrate 508, and the stopping assembly 510 is used to stop the material from leaving the detection area. In actual use, the rotating shaft 501 conveys the material to the detection area, and the material sensor 709 senses the material and sends a signal to the driving cylinder 512, so that the driving cylinder 512 drives the stopping member 511 to move to the bearing surface of the rotating shaft 501 and stop the movement of the material. When the visual inspection device 4 has finished shooting, the driving cylinder 512 drives the stopping member 511 to move out of the bearing surface of the rotating shaft 501, so that the material can continue to move. By setting the stopping assembly 510, it can be avoided that the material moves when the visual inspection device 4 is shooting or filming, thereby preventing the image from being unclear, which has the effect of ensuring accurate detection.

[0049] Specifically, the second driving module 509 includes a second slide rail 701 arranged on the supporting frame 3, a second slider 702 slidingly arranged on the second slide rail 701, a rotating screw 703, a movable nut 704 movably arranged on the rotating screw 703, and a fourth driving motor 705 for driving the rotating screw 703 to rotate. The first conveying substrate 507 is arranged on the second slider 702, and the movable nut 704 is detachably installed and fixed to the first conveying substrate 507.

[0050] In this embodiment, the second drive module 509 further includes a synchronous wheel 706 and a driven wheel 707 disposed on the rotating screw 703, and a synchronous belt 708 rotatably connected to the synchronous wheel 706 and the driven wheel 707. There are two rotating screws 703, and the fourth drive motor 705 drives the two rotating screws 703 to move at the same speed via the synchronous wheel 706, the driven wheel 707, and the synchronous belt 708.

[0051] Specifically, the double-sided illumination adjustable detection device further includes a device housing 2 , which is provided with a cavity and covers the device body 1 .

[0052] In this embodiment, the device housing 2 is used to protect the device body 1 from external interference, providing a dust-free and pollution-free environment for the device body 1. Furthermore, it prevents technicians from accidentally entering the device's moving track and being struck by the device, potentially causing accidents. The device housing 2 is equipped with a human-computer interaction device 201, which includes an industrial computer, a display screen, a keyboard, and a mouse. This device 201 allows technicians to monitor and / or control the operation of the device. When the user faces the display screen, the device housing 2 is provided with feed ports 202 on both sides. These feed ports 202 are used to transport materials in and / or out. Since the conveyor device 5 operates in a single direction, the right feed port 202 of the device housing 2 is used for feeding materials, while the left feed port 202 is used for discharging materials, and vice versa. The double-sided irradiation detection device can be connected to equipment in other processes via the conveyor device 5. Specifically, materials completed in other processes are transported into the double-sided irradiation detection device via the conveyor device 5, and the inspected materials are then transported to equipment in other processes via the conveyor device 5.

For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
