Blank off-line grade judgment device and method

Abstract

The invention discloses an off-line grade judging device for tire blanks. The off-line grade judging device comprises a main control module, a logistics conveying roller way, a tire blank holding and clamping mechanism, a tire blank supporting and detecting mechanism and a tire blank distributing mechanism. The main control module is connected with and controls other modules; the logistics conveying roller way is connected with the green tire distributing mechanism, the green tire supporting and detecting mechanism is arranged on the front side of the green tire distributing mechanism and used for detecting green tires, and the green tire clamping mechanism is arranged on the front side of the green tire supporting and detecting mechanism and used for grabbing and controlling the green tires to complete detection; and the tire blank shunting mechanism completes tire blank shunting according to a detection result of the tire blank holding and clamping mechanism. According to the invention, the tire blank is detected before being vulcanized, so that the grade of the tire blank is judged in advance, unqualified products are directly returned to be repaired or scrapped, and one-time vulcanization and inspection work is reduced; and qualified products are also graded and marked in advance, so that the efficiency of the inspection process is improved, and the technical blank that only finished tires can be inspected but tire blanks cannot be inspected in advance in the current world tire manufacturing process is solved and filled up.

Description

Technical field: [0001] The invention belongs to the field of tire manufacturing, and in particular relates to an off-line tire embryo grading device and method. Background technique: [0002] After two processes of molding and vulcanization, the tire embryo enters the inspection process. After the semi-finished tires are deburred and appearance inspected, they are also inspected for air bubbles, lack of glue, defects, out-of-roundness, uniformity, and balance, and then graded , Qualified products are classified into storage, and unqualified products are repaired or dropped from storage. The current detection method is not perfect, and some unqualified products still escape. After the tire embryo is shaped on the molding machine, it can be tested, but it is unrealistic to install testing equipment on all molding machines, and the cost is too high. Embryo inspection has the following problems. The tire has a large sidewall area and needs multi-directional inspection; differe...

Problems solved by technology

After the tire embryo is shaped on the molding machine, it can be tested, but it is unrealistic to install testing equipment on all molding machines, and the cost is too high

Embryo inspection has the following problems. The tire has a large sidewall area and needs multi-directional inspection; different light irradiation angles and occlusions will cause image defects; different light source directions will also affect defect imaging. It was found that the shadow of bubbles could not be captured; the number of detectable defects was small, which could not meet the production needs; the laser spot was larger than the defects, and the bubbles could not be effectively displayed; the identification of inconspicuous defects (bubbles) was extremely difficult and required continuous testing and optimization
