An industrial camera support structure for detecting appearance defects of cigarette boxes

Abstract

The present invention relates to the technical field of cigarette box inspection, and provides an industrial camera support structure for inspecting appearance defects of cigarette boxes. When a motor rotates, a first slider rotates, and the first slider drives a first slide bar to rotate circumferentially. The first slide bar slides longitudinally along a first through hole under the action of a spring. The first slide bar always maintains a tendency to slide toward a holding block under the elastic force of the spring. The low holding block drives the second slider to slide along the second slide bar between a third slide bar and a limit plate, and at the same time drives the second slide bar to slide between two limit blocks of the third bar, so that the industrial camera on the mounting seat makes a rectangular motion trajectory. Under the action of the opposite attraction between the first permanent magnet block and the second permanent magnet block, the lens of the industrial camera can always be kept facing the direction of the inner cigarette box, so that the distance between the industrial camera and each outer surface area of ​​the cigarette box is the same, and photo data with consistent depth of field is obtained, which is convenient for comparison with standard data preset by a computer.

Description

Technical Field

[0001] The present invention relates to the technical field of cigarette box detection, and in particular to an industrial camera support structure for detecting appearance defects of cigarette boxes. Background Art

[0002] Cigarette boxes have an image printed on their exterior surfaces. If the image's position, color, or shape, as well as the box's overall shape, are imperfect, consumers will be less likely to buy the product. Therefore, an industrial camera is positioned on each exterior surface of the box. Each camera captures a specific area of ​​the box's exterior. The data is then uploaded to a computer and compared with pre-set standard data to screen out boxes with appearance defects, improving the packaging quality rate. However, the intersection of adjacent exterior surfaces creates a blind spot for the camera.

[0003] Currently, an industrial camera is mounted on the outside of a cigarette box, rotating in a circular motion around the box. This allows the camera to capture images from all around the box, reducing blind spots. However, existing cigarette boxes are rectangular, and the industrial camera's circular motion around the box's perimeter means the distance between the camera and the center of the box's outer surface is unequal to the distance between the camera and the edges. This results in varying depths of field for each area, complicating comparison with pre-stored standard data after uploading the image to a computer. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an industrial camera support structure for detecting appearance defects of cigarette boxes, so that the lens of the industrial camera can always be directed towards the four outer surfaces of the cigarette box being inspected, and the industrial camera rotates along a rectangular trajectory around the outer surface of the cigarette box being inspected, so that when the industrial camera shoots various areas of the cigarette box, the distance between the industrial camera and the various outer surface areas of the cigarette box can be kept the same, thereby obtaining photo data with consistent depth of field, which is convenient for comparison with standard data preset by the computer.

[0005] The present invention solves the above-mentioned technical problems through the following technical means: an industrial camera support structure for detecting appearance defects of cigarette boxes, comprising a motor fixed on a frame, the output shaft of the motor being vertically arranged; and a first slider fixedly connected to the output shaft of the motor, the first slider being provided with a first through hole, the axis of the first through hole being perpendicular to the axis of the output shaft of the motor; and a first slide rod passing through the first through hole, a supporting block being fixed to one end of the first slide rod; and a spring arranged on the outside of the first slide rod, the spring being located between the first slide rod and the supporting block; and a second slide rod rotatably connected to the supporting block, the second slide rod being located below the supporting block, the second slide rod being provided with a second through hole; and a second slide rod passing through the second through hole, the second slide rod being slidably connected to the second slide rod, and a limit plate being provided at one end of the second slide rod. And, a third slide rod is placed horizontally, and the end of the second slide rod away from the limit plate is slidably connected to the third slide rod, and limit blocks are provided at both ends of the third slide rod, the second slide rod is located between the two limit blocks, and the axis of the second slide rod is perpendicular to the axis of the third slide rod; and a mounting base rotatably connected to the second slider, a first permanent magnet block is fixed on one outer surface of the mounting base; and a second permanent magnet block is fixed directly below the first slider.

[0006] Among them, a notch is provided on the second sliding rod, and the notch extends along the longitudinal axis of the second sliding rod. The interior of the second sliding rod is hollow, and a thread is provided on the inner wall of the second sliding rod, and a first stud is matched with the thread. The limiting disk is integrally formed with a protrusion, and the protrusion is located in the notch. The limiting disk is slidably connected to the second sliding rod, and the first stud protrusion is supported.

[0007] The two limit blocks are slidably connected to the third slide bar. A threaded hole is provided on the limit block. A second stud is matched with the threaded hole. The second stud is supported by the third slide bar.

[0008] A frame is fixedly connected to the mounting seat. The frame is located at the bottom of the mounting seat. One end of the frame is open, and the opening and the first permanent magnet block are located on the same side of the mounting seat.

[0009] Among them, a reinforcement piece is provided on the output shaft of the motor. The reinforcement piece is L-shaped, one end of the reinforcement piece is fixedly connected to the frame, and the other end of the reinforcement piece holds the bottom of the first slider and is slidably connected to the first slider.

[0010] Beneficial effects of the present invention:

[0011] The first and second limit blocks of the third rod are driven by the spring to move relative to each other, so that the first and second limit blocks of the third rod can be moved relative to each other, so that the industrial camera on the mounting base can make a rectangular movement trajectory. In addition, under the action of the opposite magnets between the first and second permanent magnets, when the industrial camera moves on the outer surface of the cigarette box according to the rectangular trajectory, the lens of the industrial camera can always be directed towards the direction of the inner cigarette box, so that when the industrial camera shoots various areas of the cigarette box, the distance between the industrial camera and the various outer surface areas of the cigarette box can be kept the same, so as to obtain photo data with consistent depth of field, which is convenient for comparison with preset standard data.

[0012] Second, by rotating the first stud, the protrusion on the first stud is pressed against and pushed to slide along the notch along the longitudinal extension direction of the second slide rod. The protrusion drives the limit plate to slide relative to the second slide rod. By adjusting the depth of the first stud rotated to the second slide rod, the distance between the limit plate and the third slide rod can be adjusted, thereby adjusting the width of the industrial camera's travel track to adapt to the detection of cigarette boxes of different widths.

[0013] 3. Slide the limit block relative to the third slide bar, and then rotate the second stud to abut against the third slide bar to fix the position of the limit block on the third slide bar, adjust the distance between the two limit blocks, and thus adjust the length of the bra track of the industrial camera to adapt to the detection of cigarette boxes of different lengths.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 4 As shown, an industrial camera support structure 100 for detecting appearance defects of cigarette boxes of the present invention includes a motor 10 fixed on a frame. The motor 10 is located above a conveyor belt that transmits the outer surface of the cigarette box to be inspected. The output shaft of the motor 10 is vertically downward. A first slider 20 is welded to the lower end of the motor 10. A first through hole 21 is opened on the first slider 20. A first slide rod 30 passes through the first through hole 21. The first slide rod 30 is transitionally matched with the first through hole 21. The axis of the first slide rod 30 is perpendicular to the axis of the output shaft of the motor 10.

[0021] A supporting block 31 is welded at one end of the first slide rod 30, and a spring 22 is fixed between the supporting block 31 and the first slider 20. The spring 22 is located on the outside of the first slide rod 30. Under the elastic force of the spring 22, the first slide rod 30 maintains a tendency to slide toward the supporting block 31 relative to the first slider 20.

[0022] A second slider 40 is rotatably connected to the side of the abutment block 31 facing the cigarette box. The second slider 40 has a second through-hole 41 formed horizontally therein. A second slide rod 50 extends through the second through-hole 41 and is adapted to fit into the second through-hole 41. A limit plate 51 is detachably connected to one end of the second slide rod 50. A third slide rod 60 is slidably connected to the other end of the second slide rod 50. The axis of the second slide rod 50 is perpendicular to the axis of the third slide rod 60. Limit blocks 62 are detachably connected to both ends of the third slide rod 60.

[0023] The lower surface of the second slider 40 is rotatably connected to a mounting base 70, and the industrial camera for inspecting cigarette boxes is fixed in the mounting base 70. The mounting base 70 is a frame structure with an opening on one side. After the motor 10 is started, it drives the first slider 20 to rotate, and the first slider 20 drives the first slide bar 30 to rotate axially. Under the action of the first slide bar 30 and the spring 22, the second slider 40 is driven to slide back and forth along the second slide bar 50 between the limit plate 51 and the third slide bar 60. At the same time, the second slide bar 50 slides along the third slide bar 60 between the two limit blocks 62, thereby causing the industrial camera on the mounting base 70 to move around the cigarette box in a rectangular trajectory. When the industrial camera circles the cigarette box being inspected, the distance between the industrial camera and the outer surface of the cigarette box remains unchanged.

[0024] A first permanent magnet 80 is fixed to one side of the mounting base 70, with its N-pole facing inward of the industrial camera's trajectory. A second permanent magnet 90 is fixed directly below the motor 10. The second permanent magnet 90 is located on the lower surface of the first slider 20, with its S-pole located on the same horizontal plane as the first permanent magnet 80. The lens of the industrial camera on the mounting base 70 is located on the same side as the first permanent magnet 80. The oppositely charged magnets of the first and second permanent magnets 80 and 90 keep the lens of the industrial camera pointed toward the cigarette box inward of its trajectory. This allows the industrial camera to maintain a consistent distance from each outer surface of the cigarette box when photographing different areas of the cigarette box, resulting in photo data with a consistent depth of field, which is convenient for comparison with standard data preset in a computer.

[0025] Specifically, the second slide bar 50 is provided with a notch 52 extending along the longitudinal axis of the second slide bar 50. The interior of the second slide bar 50 is hollow, and the inner wall of the second slide bar 50 is provided with a thread, which is engaged with a first stud 53. A stop plate 51 is integrally formed with a protrusion 54, which is located within the notch 52. The stop plate 51 is slidably connected to the second slide bar 50, and the first stud 53 abuts against the protrusion 54. By rotating the first stud 53, the first stud 53 abuts against the protrusion 54, pushing the protrusion 54 to slide along the notch 52 in the longitudinal direction of the second slide bar 50. The protrusion 54 drives the stop plate 51 to slide relative to the second slide bar 50. By adjusting the depth of the first stud 53 to the second slide bar 50, the distance between the stop plate 51 and the third slide bar 60 can be adjusted, thereby adjusting the width of the industrial camera's travel path to accommodate the detection of cigarette boxes of different widths.

[0026] Specifically, two limit blocks 62 are slidably connected to the third slide bar 60. The limit blocks 62 are provided with threaded holes 611, which engage with second studs 61. The second studs 61 abut against the third slide bar 60. By sliding the limit blocks 62 relative to the third slide bar 60 and then rotating the second studs 61 until they abut against the third slide bar 60, the position of the limit blocks 62 on the third slide bar 60 is fixed. The spacing between the two limit blocks 62 can be adjusted, thereby adjusting the travel length of the industrial camera to accommodate the inspection of cigarette packs of different lengths.

[0027] Specifically, a frame 110 is fixedly connected to the mounting base 70. The frame 110 is located at the bottom of the mounting base 70. One end of the frame 110 has an opening 111, and the opening 111 and the first permanent magnet 80 are located on the same side of the mounting base 70. The industrial camera is placed into the frame 110 through the opening 111, and the lens of the industrial camera extends through the opening 111, which facilitates the installation of the industrial camera.

[0028] Specifically, an L-shaped reinforcement 120 is provided on the output shaft of the motor 10. One end of the reinforcement 120 is fixedly connected to the frame, while the other end of the reinforcement 120 cradles the bottom of the first slider 20 and is slidably connected to the first slider 20. The reinforcement 120 supports the first slider 20, preventing the weight of various components from being transferred to the motor 10, thereby extending the service life of the motor 10.

[0029] The motion process of the present invention is as follows: after the motor 10 is started, it drives the first slider 20 welded to its output shaft to rotate, the first slider 20 drives the first slide bar 30 to rotate, the first slide bar 30 then drives the abutment block 31 to rotate, the abutment block 31 pushes the second slider 40 to slide along the second slide bar 50, when the second slider 40 slides to the limit plate 51, the second slide bar 50 slides along the third slide bar 60 to the limit block 62, then the second slider 40 slides along the second slide bar 50 to the third slide bar 60, and finally the second slider 40 slides to the other limit block 62. During this process, the spring 22 ensures that the first slide bar 30 maintains a tendency to slide toward the abutment block 31 relative to the first slider 20, so that the first slide bar 30 automatically matches the distance between the first slider 20 and the second slide bar 50 in the rotation trajectory. The second slider 40 makes a rectangular moving track during this process, and the movement track of the mounting base 70 connected thereto is also rectangular. The movement track of the industrial camera fixed in the mounting base 70 is also rectangular, so that the distance between the industrial camera and the outer surface of the cigarette box remains unchanged during the process of the industrial camera circling the inspected cigarette box.

[0030] During this process, the oppositely charged magnets of the first permanent magnet 80 affixed to the mounting base 70 and the second permanent magnet 90 affixed below the motor keep the industrial camera's lens oriented toward the cigarette box within its trajectory. This allows the industrial camera to maintain a consistent distance from each area of ​​the cigarette box's exterior surface when capturing images of the box, producing image data with consistent depth of field, facilitating comparison with pre-set standard data in the computer.
