Screw detection solution

Screw testing equipment, fastener testing

Screw detection equipment is used to detect screw size, external tooth defects, surface defects, appearance loss, end convex burr, cross slot blockage, etc.

I. Screw detection equipment

The equipment for detecting screws can be collectively referred to as screw testing equipment. Screw detection requires the use of screw detection machine. Screw detection machine, also known as screw screening machine, screw inspection machine, screw detection equipment, used to detect screw size, external tooth defects, surface defects, appearance loss, end convex burr, cross slot blockage, etc. Conventional detection with 3 stations can be solved. Station 1: Shot from the top down, station 2: shot from the bottom up, station 3: side shot.

1. Screws that can stand on the glass are all used in the glass tray sieve machine. Using the high light transmittance of the glass plate, the cylindrical objects to be tested can be detected when placed on the glass.

2. Long screws and screws that cannot stand on the glass plate can be placed horizontally in the indexing plate for detection through the stability of the indexing plate.

Two, screw detection

Screw detection is divided into manual detection and machine detection.

1. Manual visual detection

Manual detection is the most primitive and the most commonly used method of detection. In order to minimize the outflow of defective products, the general production enterprise personnel through visual inspection of the packaging or shipped products, in order to eliminate defective products (including dental damage, mixing, rust, etc.).

2, screw screening machine equipment

Another way for the machine automatic detection, mainly the use of CCD automatic visual detection equipment, also called screw screening machine, optical image screening machine to detect.

Machine vision detection system is mainly the use of CCD camera will be detected into the target image signal, transmitted to the special image processing system, according to the pixel distribution and brightness, color and other information, into a digital signal, image processing system on these signals for a variety of operations to extract the characteristics of the target, such as area, number, position, length, Then according to the preset tolerance and other conditions output results, including size, Angle, number, qualified/unqualified, yes/no, etc., for screws and nuts may exist defects (such as cracks, misalignment, mixing, etc.) system processing and removal of defective products.
