Description

A product quality inspection device

Technical Field

The invention belongs to the technical field of construction engineering equipment, and in particular relates to a product quality inspection device.

Background technique

A board is a flat rectangular building material board usually made into a standard size, used as a component of a wall, ceiling or floor. It also refers to a metal plate made by forging, rolling or casting. It is divided into thin plates, medium plates, thick plates, extra thick plates, and flat rectangular building material boards usually made into standard sizes. The earliest boards were solid wood boards used for carpentry, used to make furniture or other living facilities. With the development of science and technology, the definition of boards is very broad. There are boards of different materials in furniture manufacturing, construction, processing industries, etc., and boards are not limited to wooden boards. Many boards are also made of metal. After the production of boards is completed, in order to ensure the quality of the boards, the boards need to be tested.

When measuring the flatness of existing plate pits, it is necessary to place the plate on a plane and then measure the plane of its surface. A depth gauge is often used for measurement. Although the depth gauge has high accuracy, its detection range is limited and it is only suitable for situations where the pits are greatly deformed. In addition, the staff needs to identify the positions of the deformations with the naked eye and then detect and record them one by one. This is more troublesome to use and requires high labor costs for the staff. The existing defective plate screening device can only meet the clamping and fixing of a single size after adjusting the size once. When facing plates of different sizes and thicknesses, the clamping and fixing size needs to be adjusted frequently, thereby greatly reducing the efficiency of strength detection.

When the plate moves to the detection table 44, the first conveyor belt 11 and the chain 25 stop rotating, and the strength of the plate is detected by the strength detection mechanism 4, and then the position of the unqualified plate detected by the radio eye 311 and the linear displacement sensor 47 is recorded by the PLC controller 71. When the unqualified plate passes through the labeling device 52, the labeling device 52 is controlled to label the unqualified plate. The label posted by the labeling device 52 can be identified by the detection electric eye 7, thereby controlling the grasping device 6 to screen out the unqualified plate, and completing the detection and screening of the unqualified plate. The device has a high degree of automation, improves production efficiency, reduces labor costs, and is easy to promote and use.
