FIG. 1 is a schematic view of an etching line of the present invention.
Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
as shown in fig. 1, the method for controlling the speed of the etching line of the present embodiment is to install a speed control transmission belt 2 on the etching line, and the method for controlling the speed of the speed control transmission belt 2 includes the following steps:
step one, identifying the real-time speed of a developing conveying belt 1, an etching conveying belt 3 and a film stripping conveying belt 4 on an etching production line;
step two, the value with the minimum real-time speed among the developing conveying belt 1, the etching conveying belt 3 and the film removing conveying belt 4 is taken;
and step three, setting the real-time speed of the speed control transmission belt 2 as the value obtained in the step two.
The speed control conveying belt 2 is arranged in front of the starting point of the developing conveying belt 1. The identification method of the first step is to compare the real-time speeds of the developing conveying belt 1, the etching conveying belt 3 and the film stripping conveying belt 4 with each other to obtain the minimum real-time speed value. The comparison method comprises the step of sequencing the real-time speed of the developing conveying belt 1, the real-time speed of the etching conveying belt 3 and the real-time speed of the film stripping conveying belt 4 so as to obtain the minimum real-time speed value. The sorting method comprises ascending and descending. The comparison method can also be a comparison method which comprises the steps of comparing the real-time speed of the developing conveying belt 1 with the real-time speed of the etching conveying belt 3, and taking the first smaller value of the real-time speed of the developing conveying belt 1 and the real-time speed of the etching conveying belt 3; and comparing the first smaller value with the real-time speed of the film removing transmission belt 4, and taking a second smaller value between the first smaller value and the second smaller value, wherein the second smaller value is the minimum real-time speed value among the developing transmission belt 1, the etching transmission belt 3 and the film removing transmission belt 4.
Since the speed at which the products travel through the etching line at different stages is different, i.e., the distance between adjacent products varies from stage to stage, the products may travel farther and closer together. For example, if the speed of the developing transport belt 1 is 4.5m/min, the speed of the etching transport belt is 2.5m/min, and the speed of the film removing transport belt 4 is 3.0m/min, the pitch of the products on the developing transport belt 1 is larger than that on the film removing transport belt 4, and the pitch on the etching transport belt is smaller. Therefore, in order to exert the function of the speed control conveying belt 2, the real-time conveying speed of the speed control conveying belt 2 is consistent with the minimum real-time conveying speed of the developing conveying belt 1, the etching conveying belt 3 and the film removing conveying belt 4. For example, the real-time speed of the developing conveyor belt 1 is 4.5m/min, the real-time speed of the etching conveyor belt is 2.5m/min, the real-time speed of the film stripping conveyor belt 4 is 3.0m/min, and the real-time speed of the speed control conveyor belt is 2.5 m/min. The real-time speed of the three conveyor belts changes, so does the real-time speed of the speed control conveyor belt 2. For example, the real-time speed of the developing conveyor belt 1 is 5m/min, the real-time speed of the etching conveyor belt is 6m/min, the real-time speed of the film stripping conveyor belt 4 is 4.5m/min, and the real-time speed of the speed control conveyor belt is 4.5 m/min. For example, the real-time speed of the developing conveyor belt 1 is 3m/min, the real-time speed of the etching conveyor belt is 4m/min, the real-time speed of the film stripping conveyor belt 4 is 2.5m/min, and the real-time speed of the speed control conveyor belt is 2.5 m/min.
The developing transmission belt 1, the etching transmission belt 3 and the film removing transmission belt 4 are sequentially arranged, a first connecting section 5 is arranged between the developing transmission belt 1 and the etching transmission belt 3, and a second connecting section 6 is arranged between the etching transmission belt 3 and the film removing transmission belt 4. The first connecting section 5 and the second connecting section 6 are both transmission rollers.
In use, product enters the speed control conveyor 2 and travels on the speed control conveyor 2 towards the development conveyor 1. And then sequentially passes through the first connecting section 5, the etching conveying belt 3, the second connecting section 6 and the film removing conveying belt 4 to carry out corresponding developing, etching and film removing operations. Due to the fact that the speed control transmission belt 2 is arranged, the distance for the operator to start to transmit products can be accurately controlled when the operator carries out the board loading, and time waste, productivity waste and cost waste caused by the fact that the operator puts the board too far cannot occur. Through the speed adjustment of speed control transmission band 2, develop the speed difference between transmission band 1, etching transmission band 3 and the film stripping transmission band 4 to also can prevent the product because the speed is different between each transmission band in the transmission process, back end speed leads to product stack board, cardboard than anterior segment speed is slow.
According to the speed control conveying belt 2, the speed difference among the developing conveying belt 1, the etching conveying belt 3 and the film removing conveying belt 4 is planned by adjusting the speed of the speed control conveying belt 2, so that the problems of product stacking and clamping caused by the speed difference among the developing conveying belt 1, the etching conveying belt 3 and the film removing conveying belt 4 can be solved; the upper plate of the operator can be more accurate.
The embodiments of the present invention are merely illustrative, and not restrictive, of the scope of the claims, and other substantially equivalent alternatives may occur to those skilled in the art and are within the scope of the present invention.
