Description

A 45-degree inclination detection device for plastic pallets

technical field

The utility model relates to the field of logistics equipment detection, more specifically, the utility model relates to a detection device installed at an inclination angle of 45 degrees with a plastic pallet conveyor belt.

Background technique

Plastic pallet is a kind of logistics pallet. It has strong plasticity in structure, shape and size. Different plastic materials can be selected according to specific application requirements. At present, there are three commonly used plastic pallets: thermoplastic pallets, thermosetting plastic pallets and elastomers. There are two types of thermoplastic trays, crystalline and amorphous, which soften when heated; thermosetting plastic trays are heated until the material is chemically decomposed, and maintain their original hardness without softening, and their dimensions are relatively stable; when elastomers are heated, they do not flow and their dimensions are relatively stable.

Because plastic pallets are often exposed to sunlight, beatings, collisions, scratches, etc. during normal use, the plastics will be aging, cracked, chipped, broken, twisted and other appearance damage and mechanical damage after long-term use, so that they cannot continue to be used. Forklift, automatic stacker operation.

At present, the access inspection of plastic pallets includes mechanical strength inspection, appearance inspection, etc. Unqualified plastic pallets will not be allowed to enter the logistics system, but the elimination inspection of plastic pallets can only be done manually, with the naked eye and experience. Uniform standards and scientific basis. The detection of individual differences is large, the randomness is large, and the efficiency is low, resulting in the waste of plastic trays.

Using machine vision to detect the appearance of plastic pallets is an effective solution for the automation of plastic pallet detection. Since the damaged position of the plastic pallet is mainly concentrated on the four sides, in order to speed up the detection, it is necessary to detect the four sides simultaneously. On the automatic detection line of plastic pallets, it is easier to install the industrial camera installed perpendicular to the conveyor belt, but the industrial camera installed in the moving direction of the conveyor belt cannot be installed. The technical difficulty is that the industrial camera takes pictures of the side of the pallet and must be installed on the conveyor belt to block the movement position of the plastic pallet.

The solution is to choose the lifting industrial camera installation, that is, when the plastic pallet is sent to the detection station, the industrial camera rises without affecting the movement of the plastic pallet. After the plastic pallet moves to the detection station, the industrial camera falls to the detection position. For the detection of plastic pallets, this technical solution requires the industrial camera lifting mechanism to have high mechanical precision and stability, which increases the cost of equipment.

Another solution is to install an industrial camera obliquely to the side of the plastic pallet. The position of the industrial camera is not on the conveyor belt of the plastic pallet. Measurement.
