Problems solved by technology
[0002] During the vulcanization process of the tire mold, dirt such as rubber dirt and oil will continue to adhere to the surface. Therefore, it is necessary to properly clean the mold surface and remove dirt to ensure the product quality of continuous production. Currently, dry ice and sandblasting are mainly used for cleaning the pattern blocks. , Laser, if the automatic cleaning method is used, in order to ensure that the cleaning is close to the normal direction, it is necessary to input the specific shape data of the pattern block or import the pattern block model, but the measurement is cumbersome or the corresponding pattern block model is required, which affects the cleaning efficiency

Embodiment Construction
[0034] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.
[0035] Such as Figure 1 to Figure 3 Shown, a kind of tire mold block cleaning method comprises the following steps:
[0036] Calibrate the position parameters of the measurement system, adjust the measurement coordinate system through the program, and align the measurement system coordinate system with the cleaning equipment coordinate system. Among them, the X axis in the measurement coordinate system preferably corresponds to the width direction of the pattern block, and the Y axis preferably corresponds to the pattern block. In the height direction of the facade, the Z axis preferably corresponds to the thickness direction of the pattern block;
[0037] Use the measuring sensor to scan the caliber 2 of the pattern block and the inside of the cavity 1 along the facade of the pattern block to obta...

The invention discloses a tire mold pattern block cleaning method, and belongs to the field of tire mold cleaning. The method comprises the following steps: unifying a measuring system coordinate system and a cleaning equipment coordinate system; scanning the caliber of a pattern block and the interior of a cavity by using a measuring sensor in the direction of the vertical face of the pattern block to acquire point cloud data; extracting data representing the caliber of the pattern block from the point cloud data; through interpolation fitting of spline curves, are complementing missing values, which cannot be measured due to pattern rib blocking, of a cavity surface of the pattern block cavity, meanwhile, acquiring the curve contour of the cavity surface, carrying out scanning in the thickness direction of the pattern block, and acquiring point cloud data; acquiring the radian and diameter of the pattern block caliber arc and the starting point position of the pattern block caliber; and according to the obtained data, calculating the swinging angle and the moving position of a cleaning laser head when the pattern block is cleaned, and generating corresponding machining codes. The manual workload can be reduced through the steps, and meanwhile measurement errors and errors caused by human factors are avoided.
Description
technical field [0001] The invention relates to the field of tire mold cleaning, in particular to a tire mold pattern block cleaning method. Background technique [0002] During the vulcanization process of the tire mold, dirt such as rubber dirt and oil will continue to adhere to the surface. Therefore, it is necessary to properly clean the mold surface and remove dirt to ensure the product quality of continuous production. Currently, dry ice and sandblasting are mainly used for cleaning the pattern blocks. , Laser, if the automatic cleaning method is used, in order to ensure that the cleaning is close to the normal direction, it is necessary to input the specific shape data of the pattern block or import the pattern block model. However, the measurement is cumbersome or the corresponding pattern block model is required, which affects the cleaning efficiency. [0003] In view of the above-mentioned problems in the prior art, the present invention designs and manufactures a ...
