Technical Field
[0001] This utility model relates to the field of bearing processing technology, and in particular to a developing machine with a baking structure for circuit board production. Background Technology
[0002] A developing machine for circuit board production is an indispensable piece of equipment in the circuit board manufacturing process. The basic principle is to first irradiate and develop the photoresist film applied to the surface of the circuit board to reveal the circuit pattern, and then use the chemical solution of the developing machine to remove the unreinforced copper foil parts, thereby retaining only the required circuit pattern.
[0003] A developing machine for flexible circuit board processing, patent number CN216351776U, includes a main module, a developing module, and a cleaning module. The main module includes a base, a placement plate fixed to the top of the base, a moving component disposed in the inner cavity of the placement plate and extending upward from the placement plate, and a protective cover fixed to the top of the placement plate. The base is rectangular and is used to install the developing module. A movable door is installed on the outer side of the base for opening and cleaning a first storage box and a second storage box. The placement plate is fixed to the top of the base, and a through hole is opened at the connection between the placement plate and the base for the developing solution and water to fall into the first storage box and the second storage box. The moving component includes a drive shaft installed in the inner cavity of the placement plate. This developing machine for flexible circuit board processing has the advantages of thorough dissolution of the photosensitive layer, fast dissolution speed, high developing efficiency, and recycling of the developing solution.
[0004] While the aforementioned technology can spray developing solution onto the circuit board using a spray assembly, it is inconvenient to flip the circuit board during the spraying process, resulting in poor developing effect. Furthermore, it is inconvenient to dry the circuit board after developing. Therefore, a developing machine with a baking structure for circuit board production is needed to solve the above problems.

Through the rotation of the connecting shaft, the circuit board is flipped over, allowing for double-sided development and cleaning, resulting in better performance during both processes.
[0015] With a baking structure, after the circuit board is cleaned, two sets of drying racks can be used to dry both sides of the circuit board with hot air. Furthermore, the multiple drying nozzles can improve the drying effect, thus completing the drying process. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model embodiment provides a developing machine with a baking structure for circuit board production, such as... Figures 1-7 As shown, it includes a developing tank 1 and a moving tank 2; the moving tank 2 is opened inside the developing tank 1, a developer nozzle 7 is installed on one side of the developing tank 1, a developer connecting pipe 4 is installed on the top of the developer nozzle 7, a material conveyor belt 8 is installed on the bottom of the developer nozzle 7, a cleaning water nozzle 9 is provided on one side of the developer nozzle 7, a water pipe 3 is installed on the top of the cleaning water nozzle 9, a flipping structure 6 is provided on one side of the material conveyor belt 8, and a baking structure 5 is provided on the other side of the moving tank 2.
[0026] In a further preferred embodiment of this utility model, such as Figures 1-7 As shown: The flipping structure 6 includes a motor 601, a connecting shaft 602, a flipping plate 603, a mounting frame 604, a first gear 605, and a second gear 606. The mounting frame 604 is fixed to the rear end of the developing box 1. The first gear 605 is installed inside the mounting frame 604, and the second gear 606 is installed on one side of the first gear 605. The connecting shaft 602 is fixed to one end of the second gear 606, and the flipping plate 603 is fixed to the outside of the connecting shaft 602. The motor 601 is fixed to the rear end of the first gear 605. Multiple sets of teeth are fixed to the outside of the first gear 605. The multiple sets of teeth are arranged in a ring with equal spacing on the outside of the first gear 605. Several flipping plates 603 are provided, and the several flipping plates 603 are welded together with the connecting shaft 602. Teeth are provided on the outside of the second gear 606, and the first gear 605 and the second gear 606 mesh with each other.
[0027] Specifically, during the development of the circuit board, the circuit board is placed at the top of the conveyor belt 8. After placement, the developer connection pipe 4 is connected to the external developer pipeline. After connection, the developer is sprayed out through the developer nozzle 7, so that the developer falls onto one side of the circuit board for development. As the circuit board moves, when the circuit board moves to one side of the connecting shaft 602, it enters the angle between the flip plate 603 under the push of the conveyor belt 8. At this time, the motor 601 drives the first gear 605 to rotate. When the first gear 605 rotates, it drives the second gear 606 to rotate through the outer teeth. When the second gear 606 rotates, it drives the flip plate 603 to rotate, thereby flipping the circuit board. When the flipped circuit board falls onto the surface of another set of conveyor belts 8, it will move on the other set of conveyor belts 8. At this time, the sprayed developer will develop the other side of the circuit board, completing the double-sided development of the circuit board, making the development effect of the circuit board better.
[0028] In a further preferred embodiment of this utility model, such as Figures 1-7 As shown: The baking structure 5 includes a through pipe 501, a drying conveyor belt 502, a through hole 503, a drying rack 504, and drying nozzles 505. The drying conveyor belt 502 is installed on one side inside the developing box 1. The surface of the drying conveyor belt 502 has through holes 503. The drying rack 504 is installed on one side of the drying conveyor belt 502. A drying nozzle 505 is installed at one end of the drying rack 504. The through pipe 501 is fixed at the rear end of the drying rack 504. There are two sets of drying racks 504. The two sets of drying racks 504 are symmetrically distributed inside and at the top of the drying conveyor belt 502. There are several drying nozzles 505. The several drying nozzles 505 are arranged at equal intervals at one end of the drying rack 504.
[0029] Specifically, the developed circuit board is moved to the bottom of water pipe 3, and then water pipe 3 is connected to a water pump to spray water to clean the surface of the circuit board. Then, the circuit board is flipped over in the same way to clean both sides of the circuit board, so that the cleaning effect is better. The cleaned circuit board is moved to the surface of the drying conveyor belt 502. At this time, the external drying pipe is connected to the through pipe 501, and hot air is discharged into the interior of the drying rack 504 through the through pipe 501, and then sprayed out through the drying nozzle 505. Since the drying rack 504 is equipped with two sets, the circuit board can be dried on both sides to remove the moisture on the surface of the circuit board, so as to improve the quality of the circuit board, thereby completing the developing and drying work of the circuit board.
[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
