Description

Technical Field

[0001] This utility model relates to the field of industrial automation, and more particularly to an automated product quality testing device. Background Technology

[0002] Existing intelligent inspection devices lack precision in detecting minute defects and details, and their automation level is insufficient. They still rely on manual rule design for cross-modal feature association, resulting in poor generalization performance. They struggle to process large amounts of data quickly and have limited compatible detection categories. Although deep learning has been introduced to improve classification accuracy, the scarcity of training data and the high cost of annotation in industrial scenarios make model transfer difficult, and significant performance degradation still occurs under extreme conditions. The inspection industry has broad application prospects and market demand. To meet the market demand for detecting minute defects in industrial products (such as gears, screws, etc.), we urgently need an automated product quality inspection device to achieve high-precision and high-efficiency product inspection.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-4 As shown, an automated product quality inspection device includes a defect inspection station 1, an infrared scanner 2, a robotic arm 3, and a computer. The robotic arm 3 picks up products (industrial parts such as gears and screws) transported to a designated location via a conveyor belt 4, and then places the product to be inspected on the defect inspection station 1. The defect inspection station 1 performs a preliminary inspection of the product's exterior. After confirming that the surface is undamaged, the infrared scanner 2 is activated to perform an internal scanning inspection. The computer integrates and analyzes the detected data and outputs the results. The defect inspection station 1 has a housing 11 containing a stripe component and a recognition component. The housing 11 primarily protects the stripe component and recognition component from external interference, improving inspection accuracy. The recognition component is connected to the computer. For identification calculations, the housing 11 is fixedly installed inside the precision lifting platform 12 used to fix the industrial camera. The precision lifting platform 12 is driven by a motor, which controls the lifting and rotation. It has a high-precision slide rail and platform. The industrial camera is a high-resolution camera equipped with a lens and image sensor. The power data cable of the industrial camera is connected to the computer. It can move vertically through the slide rail of the precision lifting platform 12. The computer includes a control unit and a data processing unit. It is connected to each component via Bluetooth to control the operation of the entire device. An LED light source board is mounted on the top of the housing 11 using a fixed bracket. It is connected to the computer control module via a power cable. The LED light source board consists of multiple LED beads arranged in a rectangular array to provide uniform illumination.

[0018] The infrared scanner 2, consisting of an infrared sensor 21 and a processor 22, is mounted on the front end of the housing 11. Connected to a computer via a data cable, the infrared scanner 2 is a crucial detection device. It utilizes a high-hardness scanner motherboard and base for support. For some basic components, we use C-shaped fiberglass as the cylindrical endoscope, characterized by high transparency and high thermal stability, used to manufacture the heat insulation sleeve inside the lens to prevent deformation due to temperature differences during use. We also use S-shaped fiberglass as the convex mirror, characterized by high transparency and high strength and modulus, used to manufacture load-bearing components such as the lens housing, ensuring the structural strength of the lens.

[0019] The robotic arm 3 consists of multiple rotatable joints 31 and an end effector 32. It is installed in the inspection production line and the joints 31 are controlled by a motor. The end effector 32 is used to grasp objects. When designing the robotic arm 3, a base with high strength, good wear resistance and long service life is used as the supporting part of the robotic arm 3. At the same time, SBR, a lightweight material with low mass density but high tensile strength, is used as the mechanical claw.

[0020] The inspection device also includes a conveyor belt 4 installed at the bottom of the defect inspection table 1. The conveyor belt 4 is equipped with a gravity sensor. In the design of the conveyor belt 4 model, cast stainless steel with good load-bearing capacity is used as the side wall material; 1023 carbon steel plate with high strength, good wear resistance and long service life is used as the roller parts; and materials with high tensile strength and wear resistance are used as the conveyor belt 4 for transporting parts.

[0021] Working principle:

[0022] This utility model includes a defect detection platform 1, an infrared scanner 2, a robotic arm 3, a computer, and a conveyor belt 4. The specific process is as follows: First, the product to be inspected is placed on the platform, then picked up by the robotic arm 3 and placed on the conveyor belt 4 for transportation. After being transported to the vicinity of the inspection platform, the robotic arm 3 places the product to be inspected on the defect detection platform 1. The inspection platform's camera module, in conjunction with a telephoto lens, performs a preliminary inspection of the product's exterior. After confirming that the surface is undamaged, the infrared scanner 2 is activated to perform an internal scanning inspection. After the second inspection is completed, the robotic arm 3 picks up the inspected product. If both inspections pass, the product is placed on the lower conveyor belt 4 for transportation, and finally placed on the qualified platform by the robotic arm 3; otherwise, the product is placed on the upper conveyor belt 4 and finally moved to the unqualified platform. The inspection platform base is equipped with a gravity sensor. When there is no product, the conveyor belt 4 operates normally. When a product is placed, increasing the weight on the base, the conveyor belt 4 stops operating, reducing waste costs.
