Abstract
Description
Technical Field
[0001] The present application relates to the technical field of PCB board processing equipment, and in particular to a water blocking system for an immersion chamber. Background Art
[0002] In the PCB board, the liquid medicine is processed on the board surface by the water jet movement. During this process, the circuit or copper pillar has been formed on the surface of the product. In order to form an immersion chamber, solid rollers are installed on both sides of the immersion chamber. If the solid roller itself touches the product, it will cause damage to the circuit or copper pillar; if it does not touch the board surface, it will cause a large amount of liquid medicine to be brought out of the immersion chamber. First, it will cause insufficient liquid level in the immersion tank, resulting in low liquid level; second, the liquid medicine is easy to flow back and forth, polluting the front and back sections. Utility Model Content
[0003] In order to solve the above technical problems, the present application provides a water-blocking system for an immersion chamber, which has the advantages of preventing the exchange of chemicals front and back and contaminating the front and rear sections, while preventing the plate from being crushed and damaged.
[0004] In order to achieve the above object, the technical solution of the utility model is as follows:
[0005] A soaking chamber water blocking system comprises a box body, wherein a soaking chamber is arranged in the box body, a feed port and a discharge port are arranged on the box body, water blocking roller groups are arranged on both sides of the soaking chamber, and a solid roller group and an air cutting component for blowing off liquid are arranged in sequence between the water blocking roller group close to the discharge port and the discharge port along the plate conveying direction.
[0006] To implement the above technical solution, most of the medicine adhering to the plate is removed by the setting of the water-blocking roller group, and then further scraped by the solid roller group, and a small amount of liquid adhering to the plate is blown off by the air-cutting component, thereby ensuring the cleanliness of the plate, thereby preventing the medicine from flowing back and forth and contaminating the front and rear sections. Moreover, due to the setting of the air-cutting component, the water-blocking roller group and the solid roller group do not need to fully contact and press the plate, thereby preventing the plate from being crushed and damaged.
[0007] As a preferred solution of the present application, the water-blocking roller group includes an upper water-blocking roller and a lower water-blocking roller, a gap is set between the upper water-blocking roller and the lower water-blocking roller, upper O-rings are sleeved on both ends of the upper water-blocking roller, and a lower O-ring arranged opposite to the upper O-ring is arranged on the lower water-blocking roller.
[0008] By implementing the above technical solution, when the plate is conveyed to the discharge port, the two sides of the plate are clamped by the upper O-ring and the lower O-ring and then conveyed forward. However, due to the gap between the upper water-blocking roller and the lower water-blocking roller, there are gaps between the upper water-blocking roller and the lower water-blocking roller and the upper and lower surfaces of the plate, and they do not contact each other, thereby preventing damage to the plate circuit or copper column and being able to scrape off most of the medicine attached to the surface of the plate, thereby reducing the overflow of medicine in the immersion chamber.
[0009] As a preferred solution of the present application, the solid roller group includes an upper solid roller and a lower solid roller, the lower solid roller is provided with a plurality of transmission sleeves, the transmission sleeve is provided with a lower transmission ring, upper transmission rings are provided at both ends of the upper solid roller, and the upper transmission rings are provided correspondingly to the lower transmission rings.
[0010] To implement the above technical solution, similar to the water-blocking roller set, the plate is squeezed between the lower transmission ring and the upper transmission ring, and while being transported forward, due to the setting of the transmission sleeve, there is an obvious gap between the lower solid roller and the upper solid roller (as shown in the figure), so that the medicine attached to the plate can fall off.
[0011] As a preferred solution of the present application, at least two groups of solid roller assemblies are provided.
[0012] The above technical solution is implemented so that the potion has sufficient time and space to fall.
[0013] As a preferred solution of the present application, the air cutting assembly includes air knives arranged on the upper and lower sides of the plate conveying direction, and the two air knives are arranged opposite to each other and are both inclined toward the immersion chamber.
[0014] To implement the above technical solution, after the plate is dehydrated by multiple solid roller groups, a small amount of medicine attached to its surface due to the capillary wetting principle can be blown off by the air knives on the upper and lower sides and fly to the immersion chamber, thereby ensuring the cleanliness of the plate, not contaminating the medicine pools at the front and rear ends, and ensuring that the plate will not be damaged.
[0015] In summary, the present application includes at least one of the following beneficial technical effects:
[0016] 1. After most of the liquid attached to the plate is removed by the water-blocking roller group, it is further scraped by the solid roller group, and a small amount of liquid attached to the plate is blown off by the air-cutting component, thereby ensuring the cleanliness of the plate, thereby preventing the liquid from flowing back and forth and contaminating the front and back sections. In addition, due to the setting of the air-cutting component, the water-blocking roller group and the solid roller group do not need to fully contact and press the plate, thereby preventing the plate from being crushed and damaged.

[0023] The following is combined with Figure 1-4 This application is described in further detail.
[0024] The present application embodiment discloses a water blocking system for a soaking chamber 2. Figure 1 A water-blocking system for an immersion chamber 2 includes a box body 1, a immersion chamber 2 is arranged in the box body 1, a feed port and a discharge port are arranged on the box body 1, a conveying mechanism 3 for conveying a plate is arranged between the feed port and the discharge port, and the conveying mechanism 3 passes through the immersion chamber 2 so that the plate can be immersed and etched by the liquid during the conveying process. Water-blocking roller groups 4 are arranged on both sides of the immersion chamber 2, and solid roller groups 5 and air-cut components 6 for blowing off liquid are arranged in sequence between the water-blocking roller group 4 near the discharge port and the discharge port along the plate conveying direction, that is, after most of the liquid attached to the plate is removed by the setting of the water-blocking roller group 4, and then further scraped by the solid roller group 5, a small amount of liquid attached to the plate is blown off by the air-cut component 6, thereby ensuring the cleanliness of the plate, thereby preventing the liquid from flowing back and forth and polluting the front and back sections.
[0025] The water-blocking roller group 4 comprises an upper water-blocking roller 41 and a lower water-blocking roller 42, a gap is set between the upper water-blocking roller 41 and the lower water-blocking roller 42, upper O-rings 43 are sleeved on both ends of the upper water-blocking roller 41, and a lower O-ring 44 is set on the lower water-blocking roller 42 and is arranged opposite to the upper O-ring 43, so that when the plate is conveyed to the discharge port, both sides of the plate are clamped by the upper O-ring 43 and the lower O-ring 44 and then conveyed forward, but because of the gap between the upper water-blocking roller 41 and the lower water-blocking roller 42, there is a gap between the upper water-blocking roller 41 and the lower water-blocking roller 42 and the upper and lower surfaces of the plate, and they will not contact, thereby preventing damage to the plate circuit or copper column, and at the same time being able to scrape off most of the liquid medicine attached to the surface of the plate, thereby reducing the overflow of the liquid medicine in the immersion chamber 2.
[0026] A water-blocking plate 7 is provided below the lower water-blocking roller 42 . The gap between the water-blocking plate 7 and the lower water-blocking roller 42 is 0.04-0.25 MM to reduce the overflow of the medicine solution and ensure the normal rotation of the lower water-blocking roller 42 .
[0027] The solid roller set 5 includes an upper solid roller 51 and a lower solid roller 52. The lower solid roller 52 is provided with a plurality of transmission sleeves 53. The transmission sleeves 53 are provided with lower transmission rings 54. Upper transmission rings 55 are provided at both ends of the upper solid roller 51. The upper transmission rings 55 are provided corresponding to the lower transmission rings 54. Similar to the water-blocking roller set 4, the plate is squeezed between the lower transmission ring 54 and the upper transmission ring 55. While being transported forward, the lower solid roller 52 and the upper solid roller 51 have an obvious gap (as shown in the figure) due to the setting of the transmission sleeves 53, so that the medicine attached to the plate can fall off. In order to ensure the dewatering effect, the solid roller set 5 is provided with at least two groups, so that the medicine has sufficient time and space to fall off.
[0028] The air cutting assembly 6 includes air knives 61 arranged on the upper and lower sides of the plate conveying direction. The two air knives 61 are arranged opposite to each other and are both inclined toward the immersion chamber 2, so that after the plate passes through the multiple solid roller groups 5 for dehydration, a small amount of medicine attached to its surface due to the capillary infiltration principle can be blown off by the air knives 61 on the upper and lower sides and fly to the immersion chamber 2, thereby ensuring the cleanliness of the plate, not contaminating the medicine pools at the front and rear ends, and ensuring that the plate will not be damaged.
[0029] The implementation principle of the water-blocking system of the immersion chamber 2 in the embodiment of the present application is as follows: most of the liquid adhering to the plate is removed by the water-blocking roller group 4, and then further scraped by the solid roller group 5, and a small amount of liquid adhering to the plate is blown off by the air cutting component 6, so as to ensure the cleanliness of the plate, thereby preventing the liquid from flowing back and forth and contaminating the front and rear sections, and at the same time preventing the plate from being crushed and damaged.
[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
