Description

Technical Field

[0001] This utility model relates to the field of outer packaging cardboard testing, and in particular to a testing device for outer packaging cardboard. Background Technology

[0002] In the packaging industry, outer packaging paperboard (such as corrugated cardboard, cardboard, etc.) is widely used for the outer protection and decoration of products. These paperboards are usually printed with key markings such as brand logos, product information, barcodes, or QR codes. To ensure the standardization and traceability of products leaving the factory, quality inspection of the markings on the paperboard before shipment is a crucial process.

[0003] Traditional inspection methods primarily rely on manual visual inspection, which is not only inefficient and labor-intensive but also prone to missed detections and misjudgments due to visual fatigue, making it difficult to guarantee quality stability. To overcome the drawbacks of manual inspection, automated visual inspection equipment has gradually been applied. While some existing automated equipment has achieved automatic feeding and image acquisition, it often has limitations in the post-inspection sorting stage. Common feeding mechanisms typically use fixed paths or linear sorting, which cannot flexibly transport cardboard to different collection areas, making it difficult to adapt to diverse production line layouts. This significantly affects sorting quality and efficiency, causing considerable inconvenience. Summary of the Invention

[0004] The purpose of this invention is to provide a detection device for outer packaging cardboard. It has an ingenious structure and can accurately divide and unload the cardboard after detection, making it efficient and convenient.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a base frame; the base frame is provided with a feeding mechanism for feeding cardboard, a guiding mechanism for guiding cardboard, a detection mechanism for detecting markings on the cardboard after feeding, and a feeding mechanism for sorting and unloading the detected cardboard. The feeding mechanism includes a base fixed on the base frame, a rotary motor fixed on the base, a rotating platform rotatably mounted on the base under the drive of the rotary motor, a feeding bracket rotatably mounted on the rotating platform, multiple guide rollers rotatably mounted on the feeding bracket, and a gripping component mounted on the feeding bracket that can grip the cardboard from the detection mechanism to the feeding mechanism. One end of the feeding bracket is rotatably connected to the rotating platform, and the other end of the feeding bracket is lifted by the drive component. The drive component includes components fixed on the rotating platform. The system includes a drive chute, a drive cylinder fixed within the drive chute, a drive slider slidably disposed within the drive chute under the drive of the drive cylinder, and a drive support rod. The two ends of the drive support rod are rotatably connected to the drive slider and the unloading bracket, respectively. The gripping assembly includes a gripping cylinder fixed to the unloading bracket, a pneumatic gripper fixed to the telescopic end of the gripping cylinder, and clamping plates disposed at each drive end of the pneumatic gripper. Each clamping plate, through gripping pneumatics driving the pneumatic gripper, and the pneumatic gripper driving, transfers the cardboard from the detection mechanism to the unloading bracket. The rotating platform, driven by a rotary motor, rotates to the unloading end. The unloading bracket, through the drive cylinder driving the drive slider and the rotational cooperation between the drive support rod and the unloading bracket, is lifted. The cardboard between the clamping plates is unloaded through the lifting of the unloading bracket, the drive of the pneumatic gripper, and the guidance of each guide roller.

[0006] Furthermore, the base is provided with a circular groove, and the bottom of the rotating platform is provided with multiple bottom sliders that are adapted to the circular groove. The rotating platform is connected to the base by the cooperation of each bottom slider with the circular groove and the drive of the rotating motor.

[0007] Furthermore, the aforementioned feeding mechanism includes a feeding bracket fixed on the base frame, a drive conveyor belt located at the bottom of the feeding bracket and driven by a conveyor motor, and multiple push rods located on the drive conveyor belt that can push the cardboard out one by one. The feeding bracket is provided with a conveying channel for conveying the cardboard stacked at the bottom, and a sliding groove for the push rods to slide. The conveying channel is connected to the sliding groove. Each push rod passes through the conveying channel and the sliding groove in sequence by the drive conveyor belt and pushes the cardboard stacked at the bottom to the guiding mechanism and the detection mechanism in sequence.

[0008] Furthermore, the aforementioned guiding mechanism includes a guiding bracket mounted on a base frame. The guiding bracket is provided with a guiding channel communicating with the conveying channel. An adjusting component is provided in the guiding channel and is disposed opposite to it. The sliding groove passes through the feeding bracket and the guiding bracket. The adjusting component includes an adjusting cylinder fixed on the guiding bracket, an adjusting bracket slidably disposed in the guiding channel under the drive of the adjusting cylinder, and multiple adjusting rollers rotatably disposed on the adjusting bracket and capable of positioning and adjusting the cardboard. Each adjusting roller presses against both sides of the cardboard by the driving of the adjusting cylinder, and positions and adjusts the cardboard by pressing.

[0009] Furthermore, an electrostatic fan for removing static electricity from the cardboard is provided between the aforementioned feeding mechanism and the detection mechanism.

[0010] Furthermore, the aforementioned testing mechanism includes a testing platform fixed on a base frame, a testing bracket fixedly mounted on the testing platform, a testing motor fixedly mounted on the testing bracket, a lifting cylinder slidably mounted on the testing bracket under the drive of the testing motor, a testing camera fixedly mounted on the telescopic end of the lifting cylinder, and a testing light source located below the testing camera and adapted to the testing camera. The testing camera is moved to the top of the testing platform by the driving of the lifting cylinder by the testing motor and the driving of the lifting cylinder, and detects the markings on the cardboard through cooperation with the testing light source.

[0011] Furthermore, the aforementioned testing bracket is provided with a movable slide groove, in which a movable slider is slidably mounted. A lifting cylinder is fixedly installed on the movable slider. The output end of the testing motor is provided with a drive screw. The movable slider is provided with a drive screw hole adapted to the drive screw. The lifting cylinder adjusts the movement by driving the drive screw through the testing motor, the threaded engagement between the drive screw and the drive screw hole, and the sliding engagement between the movable slider and the movable slide groove.

[0012] This utility model has positive effects: (1) By integrating feeding, guiding, detection, gripping, sorting and unloading into one unit, this utility model realizes full automation from cardboard feeding to qualified / unqualified product sorting offline, which greatly improves production efficiency and reduces labor costs and labor intensity. The rotary motor drives the rotating platform to rotate, and the rotating platform rotates according to the detection results of the detection mechanism. When the marking on the detected cardboard is qualified, the cardboard is unloaded to the qualified side. When the marking on the detected cardboard is unqualified, the cardboard is unloaded to the unqualified side, which greatly enhances the adaptability and flexibility of the equipment, and optimizes the production line layout. The drive assembly, consisting of a drive cylinder and a drive strut, can smoothly lift one end of the unloading bracket, forming a ramp. Combined with multiple guide rollers, this allows the cardboard to slide smoothly and steadily into the collection area under gravity, avoiding jamming or drop damage. This achieves efficient and low-impact unloading. The gripping assembly uses a pneumatic gripper driven by a cylinder, which works in conjunction with a clamping plate to accurately grab the inspected cardboard from the inspection station and transfer it to the unloading bracket. The operation is reliable, avoiding scratches or creases that may be caused by manual transfer, ensuring product quality. This effectively solves the problem of low quality and low efficiency in sorting in existing technologies, greatly improving the sorting quality of cardboard after inspection. The structure is ingenious, convenient, and practical.

[0013] (2) The present invention provides stable and uniform support and precise rotation guidance for the rotating platform through the cooperation of the bottom slider and the circular groove, ensuring that the platform can still rotate smoothly and smoothly when carrying the feeding bracket, cardboard and drive components, preventing shaking and jamming, and improving the reliability and life of the equipment operation.

[0014] (3) This utility model drives the conveyor belt to drive the push rod to circulate, thereby realizing the continuous pushing of stacked cardboard from the bottom one by one, replacing manual single-sheet feeding, ensuring the matching with the rhythm of subsequent processes, and providing a stable material supply for the entire automated process. By utilizing the cooperation of the conveyor channel and the sliding groove, the movement trajectory of the push rod is precisely limited, ensuring that it can accurately act on the bottom cardboard, achieving reliable separation and pushing. The structure is simple and effective.

[0015] (4) This utility model applies pressure from both sides of the cardboard simultaneously by adjusting the cylinder to drive the adjusting bracket and the adjusting roller on it. This can automatically correct the offset generated by the cardboard during the conveying process, so that it is accurately positioned in the center channel before entering the inspection station. This provides a precise positioning basis for subsequent visual inspection, thereby improving the accuracy and reliability of the inspection. The use of rotatable adjusting rollers for pressing and guiding avoids rigid sliding friction with the edge of the cardboard, effectively preventing wear or crushing of the cardboard edge during the correction process.

[0016] (5) By setting up an electrostatic fan, this utility model can effectively eliminate the dust and fine fibers adsorbed by static electricity generated by friction during the conveying process of cardboard, remove the attached substances, and ensure that the detection camera can capture clear and interference-free identification images, which significantly reduces the misjudgment or missed judgment rate caused by unclear images.

[0017] (6) By setting up a detection mechanism, this utility model integrates a detection camera and a dedicated detection light source, providing a stable and uniform lighting environment for image acquisition, overcoming the influence of ambient light changes, and ensuring the consistency of image quality. Through the drive of the detection motor and the lifting cylinder, the height and position of the detection camera can be flexibly adjusted, making it adaptable to cardboard of different sizes and with different detection requirements, thus enhancing the versatility of the equipment.

[0018] (7) This utility model uses a detection motor to drive a drive screw to rotate. The drive screw engages with the screw hole on the movable slider, enabling precise and controllable fine-tuning of the lifting cylinder and camera position. This allows the camera to be stabilized at any set height, avoiding focal length changes caused by vibration during the detection process, and further ensuring the clarity of the detected image and the accuracy of the detection results. The cooperation between the movable slider and the movable slide ensures the smoothness of the movement process. Attached Figure Description
