[0002] Packaging boxes exhibit diverse characteristics, including regular or irregular shapes such as square, round, and irregular shapes. Their structure can be designed according to usage needs, such as folding (like common cardboard boxes, which save space during transportation and storage), fixed (like some metal boxes and plastic boxes, which have a stable structure), drawer-type (for easy access to the internal products), and flip-top type (like gift boxes, which are easy to open and have a good display effect).

[0003] In the packaging box production process, quality inspection is a key link to ensure that the product meets the standards. Traditional packaging box quality inspection mostly adopts manual visual inspection and manual measurement. This method is not only inefficient, but also greatly affected by human factors, with low detection accuracy, poor measurement compatibility and insufficient stability, making it difficult to meet the needs of modern large-scale production. To address the above problems, a measuring device for packaging box quality inspection is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a measuring device for quality inspection of packaging boxes to solve the problems mentioned in the background art.

A PLC control panel is fixedly installed on the upper end of the measuring machine base, and two guide rails are symmetrically installed on one side of the upper end of the measuring machine base. Two electric sliders are slidably connected to the upper end of the guide rails. A positioning structure is provided above the two electric sliders. A support frame is fixedly installed on the upper end of the measuring machine base above the two guide rails. A scale mark is fixedly provided on the front side of the outer wall of the support frame, and an industrial camera is fixedly installed on the rear outer wall of the support frame. The support frame has an internal adjustment structure, which includes an adjustment motor fixedly installed on the upper end of the support frame. The output end of the adjustment motor is fixedly connected to a fixing rod, and one end of the fixing rod is fixedly connected to the middle of the rotating plate. Guide rods are rotatably installed at both ends of the bottom of the rotating plate, and the other ends of the guide rods are rotatably installed on the limiting posts. The two limiting posts are respectively fixedly installed on two positioning plates, and clamping frames are fixedly installed at the bottom of the two positioning plates, and rubber pads are fixedly installed on the outer wall of the clamping frames.

[0006] As a preferred embodiment of the above technical solution, two limiting slide rods are symmetrically installed on the inner wall of the support frame, the fixing rod is rotatably installed inside the mounting plate and both ends of the mounting plate are fixedly installed on the limiting slide rods, and the positions of the two positioning plates are symmetrical to each other.

[0007] As a preferred embodiment of the above technical solution, two sleeves are fixedly installed on the upper ends of the two positioning plates, and the sleeves are slidably connected to the outer walls of the two limiting slide rods. Two sets of hinge plates are fixedly installed on the outer walls of the two clamping frames.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 5 As shown in the figure, this embodiment provides a measuring device for packaging box quality inspection, including a measuring machine 1. A PLC control panel 2 is fixedly installed on the upper end of the measuring machine 1, and two guide rails 5 are symmetrically installed on one side of the upper end of the measuring machine 1. Two electric sliders 51 are slidably connected to the upper end of the guide rails 5. A positioning structure 6 is provided above the two electric sliders 51. A support frame 3 is fixedly installed on the upper end of the measuring machine 1 above the two guide rails 5. A scale mark 4 is fixedly provided on the front side of the outer wall of the support frame 3, and an industrial camera 8 is fixedly provided on the rear outer wall of the support frame 3. The support frame 3 is equipped with an adjustment structure 7. The adjustment structure 7 includes an adjustment motor 71 fixedly installed on the upper end of the support frame 3. The output end of the adjustment motor 71 is fixedly connected to a fixing rod, and one end of the fixing rod is fixedly connected to the middle of the rotating plate 77. Guide rods 78 are rotatably installed at both ends of the bottom of the rotating plate 77, and the other ends of the guide rods 78 are rotatably installed on the limiting posts 76. The two limiting posts 76 are respectively fixedly installed on the two positioning plates 74, and clamping frames 79 are fixedly installed at the bottom of the two positioning plates 74, and rubber pads 795 are fixedly installed on the outer wall of the clamping frames 79.

[0018] like Figures 3 to 4 As shown, two limiting slide rods 73 are symmetrically installed on the inner wall of the support frame 3. The fixing rod is rotatably installed inside the mounting plate 72, and both ends of the mounting plate 72 are fixedly installed on the limiting slide rods 73. The positions of the two positioning plates 74 are symmetrical. Two sleeves 75 are fixedly installed on the upper end of each of the two positioning plates 74, and the sleeves 75 are slidably connected to the outer wall of the two limiting slide rods 73. Two sets of hinge plates 791 are fixedly installed on the outer wall of each of the two clamping frames 79. Electric push rods 792 are fixedly installed inside each of the two sets of hinge plates 791, and one end of the electric push rod 792 is fixedly connected to a connecting protrusion 793. Auxiliary side plates 794 are fixedly installed on the outer wall of each of the two connecting protrusions 793. The auxiliary side plates 794 are adapted to the position of the clamping frames 79.

[0019] By driving the adjusting motor 71 to move the two guide rods 78 on the rotating plate 77 relative to each other, the two guide rods 78 cause the positioning plates 74 on the two limiting posts 76 to slide on the limiting slide rod 73 using the sleeve 75. This causes the two clamping frames 79 to stably clamp and measure packaging boxes of different sizes. At the same time, when the packaging box is small, by driving the two sets of electric push rods 792 to move the auxiliary side plate 794 on the connecting protrusion 793 downward, so that it is aligned with the two sides of the outer wall of the measuring packaging box, and then clamped and aligned. This allows the device to adapt to packaging boxes of different shapes and specifications, with strong compatibility.

[0020] like Figure 5 As shown, the positioning structure 6 includes a placement plate 61 fixedly installed above two electric sliders 51. A drive motor 62 is fixedly installed inside the placement plate 61. A bidirectional lead screw 63 is fixedly connected to the output end of the drive motor 62. Two connecting cylinders 64 are symmetrically threaded to the outer wall of the bidirectional lead screw 63. A movable frame 65 is fixedly installed on the upper end of each of the two connecting cylinders 64, and an anti-slip clamp 67 is fixedly installed on the outer wall of the movable frame 65. Limiting sliders 66 are symmetrically installed on both sides of the outer wall of the movable frame 65, and the limiting sliders 66 are slidably connected to the upper end of the placement plate 61.

[0021] The two-way lead screw 63 synchronously drives the movable frames 65 on the two connecting cylinders 64 to move relative to each other, causing the two movable frames 65 to drive the anti-slip clamping plate 67 to clamp and position packaging boxes of different sizes. At the same time, when the two movable frames 65 move, they slide and cooperate on the placement plate 61 using the limit slider 66 to avoid errors caused by displacement during the detection process, which would affect the measurement accuracy.

[0022] The working principle and process of this utility model: The staff presets the parameter values ​​of the drive motor 62, the adjustment motor 71 and the electric slider 51 on the PLC control panel 2 in advance. First, the packaging box is placed on the placement plate 61 and the external power supply is turned on. By starting the drive motor 62, the movable frame 65 on the two connecting cylinders 64 on the outer wall of the bidirectional lead screw 63 moves relative to each other. At the same time, the two movable frames 65 drive the two anti-slip clamps 67 to move relative to each other to clamp and position the two sides of the packaging box, so as to avoid the packaging box causing errors due to displacement during the detection process. After the packaging box is positioned, the two electric sliders 51 move along the direction of the guide rail 5 to move the packaging box on the placement plate 61 to the measurement area. At this time, the adjusting motor 71 on the drive support frame 3 drives the rotating plate 77 on the fixed rod to rotate on the mounting plate 72, causing the two ends of the rotating plate 77 to rotate relative to each other. At the same time, the positioning plate 74 fixed by the limiting post 76 on the two guide rods 78 slides on the limiting slide rod 73 with the sleeve 75, thereby driving the two clamping frames 79 to move relative to each other to fit the two sides of the packaging box. The size is measured by reading the scale mark 4. Then, the industrial camera 8 acts as a vision sensor to capture the surface image of the packaging box, compare it with the standard template, calculate the pattern position offset, and transmit the data to the PLC control panel 2. The data processing module compares and analyzes the data with the qualified packaging box pattern. At the same time, when the size of the packaging box is small, the electric push rod 792 on both sides of the two clamping frames 79 drives the auxiliary side plate 794 on the connecting protrusion 793 to move downward, thereby limiting the measurement of packaging boxes of different sizes and improving its compatibility.
