Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board manufacturing technology, specifically to a pipe defoaming structure for flexible circuit board manufacturing. Background Technology

[0002] In the production of flip-chip films, inorganic alkaline solutions are used as stripping solutions and developing solutions. These inorganic alkaline solutions are prone to generating foam during the product manufacturing process, especially at the temperatures and concentrations required for product production. The foam generated by the reaction and scouring of the inorganic alkaline solutions is particularly abundant and difficult to eliminate. When the foam thickness remaining in the developing tank of the production line exceeds the height of the product, it can cause a series of quality problems such as short circuits and open circuits. Utility Model Content

[0003] In view of the problems existing in the defoaming structure of the pipeline used in the production of flexible circuit boards, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a defoaming structure for pipes used in the production of flexible circuit boards, which solves the problem that the reaction and scouring of inorganic alkaline solutions, especially at the temperatures and concentrations required for product production, will produce a lot of foam that is difficult to eliminate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A defoaming structure for flexible circuit board production includes a pipe body, a developing tank fixedly mounted on the top of the pipe body, a connecting frame fixedly mounted on the inner wall of the pipe body, a defoaming disc fixedly mounted on the top of the connecting frame, a delivery pipe fixedly mounted on one side of the pipe body, a negative pressure pump fixedly mounted on the wall of the delivery pipe, a defoaming cover fixedly mounted on the top of the defoaming disc, one end of the delivery pipe connected to the defoaming cover, a supporting guide wheel rotatably mounted on the top of the developing tank, a product body fitted to the top of the supporting guide wheel, and multiple developing solution nozzles fixedly mounted on the top of the product body.

[0006] Preferably, a cross-shaped bracket is fixedly provided on the inner side wall of the defoaming plate, and a defoaming ring is fixedly provided on the cross-shaped bracket.

[0007] Preferably, the top of the defoaming ring is fixedly provided with multiple defoaming hooks.

[0008] Preferably, the connecting frame is made of stainless steel.

[0009] Furthermore, the inner wall of the developing tank is inclined.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention features a defoaming plate equipped with a cross-shaped support, a defoaming ring, and multiple defoaming hooks. The synergistic effect of these multiple structures allows for precise puncture of foam generated by inorganic alkaline solutions, solving the problem of traditional foam removal. A negative pressure pump, in conjunction with the defoaming hood, quickly discharges the broken foam, preventing foam accumulation above the product height and effectively preventing quality defects such as short circuits and open circuits. The connecting frame is made of stainless steel, which is corrosion-resistant and has high strength, extending its service life. The inclined inner wall of the developing tank facilitates the flow of the solution and foam aggregation, improving the overall smoothness of the defoaming operation. Attached Figure Description

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0015] This utility model discloses a defoaming structure for pipes used in the production of flexible circuit boards.

[0016] This utility model provides, for example Figure 1-3The illustrated defoaming structure for flexible circuit board production includes a pipe body 1. A developing tank 2 is fixedly mounted on the top of the pipe body 1. A connecting frame 3 is fixedly mounted on the inner wall of the pipe body 1. A defoaming disc 4 is fixedly mounted on the top of the connecting frame 3. A conveying pipe 5 is fixedly mounted on one side of the pipe body 1. A negative pressure pump 6 is fixedly mounted on the wall of the conveying pipe 5. A defoaming cover 7 is fixedly mounted on the top of the defoaming disc 4. One end of the conveying pipe 5 is connected to the defoaming cover 7. A supporting guide wheel 8 is rotatably mounted on the top of the developing tank 2. A product body 9 is attached to the top of the supporting guide wheel 8. Multiple developer nozzles 10 are fixedly mounted on the top of the product body 9. The defoaming disc 4, fixed to the inner wall of the pipe body 1 by the stainless steel connecting frame 3, plays a core defoaming role. The star-shaped bracket 11 inside the defoaming disc 4 provides stable support for the defoaming disc. The bubble ring 12 ensures that the multiple defoaming hooks 13 on the ring are evenly distributed. When the collected foam comes into contact with the defoaming hooks 13, the hooks directly destroy the surface tension of the foam through physical piercing, achieving the initial breakage of the foam and solving the core problem of the foam being difficult to eliminate. The defoaming cover 7 on the top of the defoaming plate 4 will concentrate and protect the punctured foam fragments and the small foams that are not completely broken, preventing them from spreading back to other areas of the developing tank 2 or the pipeline body 1. At this time, the negative pressure pump 6 on the conveying pipe 5 on one side of the pipeline body 1 is started. The negative pressure is generated through the connection structure between the conveying pipe 5 and the defoaming cover 7, which quickly draws the foam and fragments collected in the defoaming cover 7 away from the pipeline body 1, completely preventing the foam from accumulating in the developing tank 2 beyond the height of the product body 9, and ultimately ensuring that the product avoids quality problems such as short circuits and open circuits.

[0017] To facilitate defoaming, such as Figure 3 As shown, a cross-shaped bracket 11 is fixedly provided on the inner side wall of the defoaming plate 4, and a defoaming ring 12 is fixedly provided on the cross-shaped bracket 11.

[0018] To achieve better defoaming results, such as Figure 3 As shown, the top of the defoaming ring 12 is fixedly provided with a plurality of defoaming hooks 13.

[0019] And for greater durability, such as Figure 1-2 As shown, the connecting frame 3 is made of stainless steel.

[0020] Finally, for better use, such as Figure 1 As shown, the inner wall of the developing tank 2 is inclined.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
