Description

Technical Field

[0001] The present invention relates to the technical field of anti-scratch for the diaphragm window area, and particularly relates to a protective oil film pasting device for anti-scratch processing of the diaphragm window area. Background Art

[0002] In modern industrial production, diaphragms are widely used, especially in the fields of electronics, automotive interiors, display panels, etc. In the actual production process, it is often necessary to cut many small diaphragms from a large diaphragm to meet the needs of different components. Among them, some small diaphragms have specific window areas, which undertake important functions such as light transmission and display. Therefore, ink printing is not allowed, and they are always in a bare state before the punching and injection molding processes.

[0003] From the completion of punching the diaphragm to the final entry into the injection molding process, the diaphragm needs to go through multiple links such as stacking and turnover. During this period, the bare window area is extremely likely to rub and collide with other objects, resulting in scratches, bruises and other defects. Since these damages cannot be eliminated after injection molding, a large number of scratches and bruises will eventually appear in the window area of the injection molded parts. According to statistics, the defective rate of injection molded parts caused by damage to the window area is as high as 15%-20% in some production enterprises, which not only causes material waste and increased production costs, but also greatly restricts the improvement of production efficiency and product quality. Therefore, the present application designs a protective oil film pasting device for anti-scratch processing of the diaphragm window area to solve the above problems. Summary of the Invention

[0029] Working principle: In this embodiment, the present invention also proposes a usage method of a protective oil film pasting device for preventing scratching in the diaphragm window area, including the following steps:

[0030] Step 1, diaphragm transmission: The first motor 3 starts, drives the rotating shaft connected thereto to rotate, thereby driving the conveyor belt 2 to operate, smoothly conveying the diaphragm to be processed into the device. The diaphragm moves along the conveyor belt 2 to the designated processing position, preparing for the subsequent protective oil film pasting process;

[0031] Step 2, applying the first layer of protective oil: The third motor 13 and the fourth motor 14 work together to drive the first lead screw 6 and the second lead screw 8 to rotate, precisely adjust the position of the third slider, and move the oil-brushing assembly above the diaphragm window area; The fifth motor 20 is started to drive the turntable 21 to rotate. The turntable 21 drives the scraping bar 22 to rotate. The scraping bar 22 interacts with the balls 19 on the bottom surface of the fixed box 18, causing the protective oil in the fixed box 18 to flow out through the through holes; The flowing protective oil enters the turntable 21, flows into the connecting cylinder 23 through the arc-shaped through groove, then enters the rectangular box, and penetrates to the bottom surface through the brush 24, and is evenly applied to the diaphragm window area to complete the application of the first layer of protective oil;

[0032] Step 3, curing the first layer of protective oil: The second motor 9 drives the first rotating rod 10 and the rotating plate 11 to rotate, so that the first electric push rod 12 equipped with the heating assembly rotates above the diaphragm window area; The first electric push rod 12 extends to drive the nozzle 15 close to the diaphragm. The heating fan 17 is started, and hot air is blown through the air pipe 16 through the nozzle 15 onto the applied first layer of protective oil to accelerate the curing of the oil film; At the same time, the second motor 9 rotates at most 180° and then returns to the original position to avoid the oil delivery pipe 25 from being wound and knotted, ensuring the normal operation of the device;

[0033] Step 4, applying and curing the second layer of protective oil: Repeat the operation of Step 2, and apply the second layer of protective oil evenly on the cured first-layer protective oil film through the oil-brushing assembly again; Subsequently, repeat Step 3, and use the heating assembly to heat and cure the second layer of protective oil to form a more solid protective oil film, enhancing the scratch resistance of the diaphragm window area;

[0034] Step 5, adhesive protection: The sixth motor drives the third lead screw 37 to rotate, adjusts the position of the L-shaped mounting plate 27, and aligns the adhesive component with the diaphragm window area; The tape is released from the tape reel 28, guided by the separating roller 29 and the guiding roller 30 to the guiding box 31. Under the cooperation of the second electric push rod 33 and the feeding roller 32, the position and tension of the tape are adjusted; Subsequently, the third electric push rod 34 extends to drive the flattening roller 35 to closely attach the special tape to the window area coated with the protective oil film; When the tape is applied, first start the second electric push rod 33 to contract and raise the guiding box 31 to prevent the blade from contacting the diaphragm window area during cutting and causing damage; Then the seventh motor drives the L-shaped swing rod 36 to rotate, and the blade cuts the tape to complete the adhesive protection of the diaphragm window area. This special tape can be removed before injection molding and will not leave residues affecting the quality of the diaphragm.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
