Description

Technical Field

[0001] This utility model relates to testing equipment, and in particular to an automatic defective product sorting equipment. Background Technology

[0002] In industrial production, product inspection and sorting are often required during the manufacturing process. In the production of sheet-like products, the appearance of the product is typically judged manually during loading, with the human eye checking for damage, scratches, or other defects. This requires a significant amount of manpower, is labor-intensive, and severely limits production speed. Therefore, this paper presents an automated defective product inspection and sorting device.

[0003] Currently, existing testing methods for plate-shaped products are generally only suitable for conveying products of a single size, resulting in low compatibility. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an automatic defective product detection and sorting device.

[0005] The objective of this utility model is achieved through the following technical solution: an automatic defective product detection and sorting device, comprising a frame, a conveyor belt mechanism with adjustable width on the frame, an upper detection camera and a defective product sorting robot above the conveyor belt mechanism, a lower detection camera below the conveyor belt mechanism, the upper detection camera and the lower detection camera being vertically aligned, a defective product outflow slide plate on one side of the conveyor belt mechanism, a good product outflow slide plate at the discharge end of the conveyor belt mechanism, the defective product outflow slide plate being obliquely fixed to the front side of the frame, and the good product outflow slide plate being rotatably mounted on the right side of the frame.

[0006] As an improvement to the automatic defective product sorting equipment of this utility model, the conveyor belt mechanism includes a left conveyor belt mechanism and a right conveyor belt mechanism. The side of the left conveyor belt mechanism is connected to a left mounting plate, and the side of the right conveyor belt mechanism is connected to a right mounting plate. Both the left and right mounting plates are connected to the same bidirectional lead screw via a lead screw nut. A handwheel is provided at one end of the bidirectional lead screw. Turning the handwheel clockwise reduces the distance between the left and right conveyor belt mechanisms, while turning it counterclockwise increases the distance. The bidirectional lead screw has a forward lead screw section and a reverse lead screw section. The lead screw nut on the left mounting plate is screwed to the forward lead screw section, and the lead screw nut on the right mounting plate is screwed to the reverse lead screw section. When the bidirectional lead screw rotates, the left and right conveyor belt mechanisms move in opposite directions.

[0007] As an improvement of the automatic defective product sorting equipment of this utility model, both the left mounting plate and the right mounting plate are provided with elongated holes, and the left and right conveyor belt mechanisms can be adjusted in height through the elongated holes. The bottom of both the left and right mounting plates is provided with sliders, which are slidably connected to linear slide rails, which are mounted on the frame.

[0008] As an improvement of the automatic defective product sorting equipment of this utility model, both the left conveyor belt mechanism and the right conveyor belt mechanism include a conveyor belt mounting beam. Both ends of the conveyor belt mounting beam are provided with pulleys. The two pulleys are connected by the conveyor belt. One of the pulleys is connected to the output shaft of the drive motor. The drive motor is installed on the outside of the conveyor belt mounting beam.

[0009] As an improvement to the automatic defective product sorting equipment of this utility model, the defective product sorting robot includes a lateral movement control module, which controls the movement of a picking cylinder. The piston rod end of the picking cylinder is provided with a suction cup mounting plate, and multiple suction cups are spaced apart on the suction cup mounting plate. The lateral movement control module can be a cylinder or a lateral movement servo module.

[0010] As an improvement to the automatic defective product sorting equipment of this utility model, the good product outflow slide is mounted on the right side of the frame via a rotary control cylinder. The good product outflow slide is horizontal when receiving materials. When a large number of products are received, the rotary control cylinder controls the good product outflow slide to rotate, causing the products on the slide to slide off.

[0011] As an improvement to the automatic defective product sorting equipment of this utility model, the conveyor belt mechanism transports the product to a position between the upper and lower inspection cameras, where both cameras simultaneously photograph the product. Products that fail inspection from either the front or the back are marked as defective.

[0012] As an improvement to the automatic defective product sorting equipment of this utility model, the frame is also equipped with a display screen and a control box. The display screen is electrically connected to the control box, and the conveyor belt mechanism and the defective product sorting robot are both controlled by the control box.

[0013] The beneficial effects of this utility model are as follows: This utility model adopts a rotating feeding method, and the conveyor belt mechanism can adapt to the conveying of products of various sizes, with a wide range of applications. Defective products after inspection can be removed from the conveyor belt mechanism by a defective product robot, eliminating the need for manual removal of defective products. This can prevent defective products from being transported to the same position as good products, effectively improving sorting efficiency. Attached Figure Description
