Description

Technical Field

[0001] This application relates to the technical field of resistive plate browning treatment, and in particular to a resistive plate browning treatment device. Background Technology

[0002] Resistor board browning refers to the phenomenon of a brown oxide layer appearing on the surface of a resistor board. This is usually caused by the oxidation reaction of conductive metals (such as copper) in the circuit board under specific conditions.

[0003] Removal of contaminants: Browning treatment removes contaminants such as grease and metal ions from the surface of the resistor board, improving the cleanliness of the circuit board surface. Increased surface roughness: Browning treatment increases the surface roughness of the resistor board, thereby improving the adhesion of subsequent materials such as printing paint and soldering materials. Improved corrosion resistance: The increased surface roughness also improves the corrosion resistance of the resistor board, extending its service life.

[0004] Current browning equipment includes a browning tank for holding the browning solution and a transport device for transporting the resistance plates to the browning tank for browning treatment.

[0005] The browning equipment described above simply immerses the resistor plate in the browning tank for browning treatment. However, during the treatment process, the concentration of the browning solution in the browning tank gradually decreases, resulting in a reduction in browning efficiency. Therefore, a longer immersion time than theoretically required is needed to ensure the browning effect. Although browning treatment can improve the surface quality of the resistor plate, excessive browning may cause the metal surface to become too rough, affecting the stability of electrical connections and signal transmission. Utility Model Content

[0006] To address the aforementioned technical problems, this application provides a resistive plate browning treatment device, which has the advantage of being able to precisely control the browning efficiency, thereby reducing the browning effect.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A resistive plate browning treatment device includes a box, a conveying device for conveying resistive plates is provided inside the box, and a spraying assembly for spraying atomized browning liquid onto the resistive plates is provided below the conveying device.

[0009] The conveying device is equipped with an air knife for purging the resistor plate at the end of the conveying direction of the housing.

[0010] To achieve the above technical solution, while the resistance plate is being conveyed forward within the box by the conveying device, the side of the resistance plate that needs to be browned is positioned downwards. This allows it to be sprayed with atomized browning liquid by the spraying component below during transport, thus achieving the browning treatment. The browning liquid on the resistance plate will quickly fall off due to gravity, and the resistance plate can be continuously rinsed with subsequent browning liquid, thereby ensuring the concentration of browning liquid in contact with the resistance plate and ensuring the browning effect. After browning is completed, the resistance plate is blown clean by an air knife to prevent the browning liquid from accumulating for too long and causing over-browning.

[0011] As a preferred embodiment of this application, the spraying assembly includes a plurality of spraying main pipes, which are equally spaced along the conveying direction. Each spraying main pipe is provided with a plurality of atomizing nozzles arranged in the direction of the conveying device, and a supply component for supplying browning liquid to the plurality of spraying main pipes.

[0012] The above technical solution is achieved by supplying browning liquid into the main spray pipe through the liquid supply component, and then spraying the atomized browning liquid upward through the atomizing nozzle so that it falls evenly onto the resistance plate, thereby ensuring the uniformity of browning.

[0013] As a preferred embodiment of this application, the liquid supply component includes a liquid supply tank, a heating device is provided inside the liquid supply tank, a water outlet is provided on the liquid supply tank, the water outlet is connected to several main spray pipes through a pipeline, and a liquid supply pump is provided on the water outlet.

[0014] To achieve the above technical solution, the liquid supply pump supplies the browning liquid from the liquid supply tank into the injection main pipe. The temperature of the browning liquid can be maintained by heating with a heating device, thereby ensuring the browning effect.

[0015] As a preferred embodiment of this application, a browning pool is provided below the spraying assembly.

[0016] The above technical solution enables the dripping browning liquid to be collected in the browning tank for subsequent processing and reuse.

[0017] As a preferred embodiment of this application, the conveying device includes a plurality of conveying rollers and a conveying motor for driving the conveying rollers to rotate.

[0018] To achieve the above technical solution, the conveyor motor drives several conveyor rollers to rotate synchronously through a gear set, thereby driving the resistance plate to be conveyed at a uniform speed, thus ensuring the controllability of the browning effect.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. While the resistance plate is being conveyed forward within the box by the conveying device, the side of the resistance plate that needs to be browned is positioned downwards. This allows it to be sprayed with atomized browning liquid by the spraying component below during the conveying process, thus achieving the browning treatment. The browning liquid on the resistance plate will fall off quickly due to gravity, and the resistance plate can be continuously rinsed with subsequent browning liquid, thereby ensuring the concentration of browning liquid in contact with the resistance plate and ensuring the browning effect. After browning is completed, the resistance plate is blown away by an air knife to prevent the browning liquid from accumulating for too long and causing over-browning. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses a device for browning a resistor plate. (Refer to...) Figure 1The resistor plate browning treatment equipment includes a housing 1, inside which is a conveying device 2 for transporting resistor plates. Below the conveying device 2 is a spraying assembly 3 for spraying atomized browning liquid onto the resistor plates. At the end of the conveying device 2 in the conveying direction, a wind knife 4 is installed on the housing 1 for purging the resistor plates. That is, while the resistor plates are being transported forward within the housing 1 by the conveying device 2, the side of the resistor plate to be browned is facing downwards. This allows the atomized browning liquid to be sprayed onto the resistor plates by the spraying assembly 3 during transport, thus achieving browning treatment. The browning liquid on the resistor plates falls quickly due to gravity, allowing the resistor plates to be continuously rinsed with subsequent browning liquid, ensuring the concentration of browning liquid in contact with the resistor plates and guaranteeing the browning effect. After browning is complete, the resistor plates are purged by the wind knife 4 to prevent the browning liquid from accumulating for too long and causing over-browning.

[0028] The spraying assembly 3 includes several spray pipes 31, which are evenly spaced along the conveying direction. Each spray pipe 31 is equipped with several atomizing nozzles 32 positioned towards the conveying device 2, and a supply unit for supplying browning liquid to the spray pipes 31. Specifically, the browning liquid is supplied to the spray pipes 31 through the supply unit, and then atomized browning liquid is sprayed upwards through the atomizing nozzles 32, evenly falling onto the resistance plate, thus ensuring uniform browning.

[0029] The liquid supply system includes a liquid supply tank 33, which contains a heating device 34, which can be an electric heating wire or an electric heating rod. The liquid supply tank 33 has an outlet, which is connected to several main spray pipes 31 via pipes. A liquid supply pump 35 is installed at the outlet. The liquid supply pump 35 supplies the browning liquid from the liquid supply tank 33 into the main spray pipes 31. The temperature of the browning liquid is maintained by heating it with the heating device 34, thereby ensuring the browning effect.

[0030] A browning tank 5 is provided below the spraying component 3, so that the dripping browning liquid can be collected by the browning tank 5 for subsequent processing and reuse.

[0031] The conveying device 2 includes several conveying rollers 21 and a conveying motor 22 for driving the conveying rollers 21 to rotate. The conveying motor 22 drives the several conveying rollers 21 to rotate synchronously through a gear set, thereby achieving uniform conveying of the resistance plate and ensuring the controllability of the browning effect.

[0032] The implementation principle of the resistance plate browning treatment device in this application embodiment is as follows: While the resistance plate is conveyed forward within the housing 1 by the conveying device 2, the side of the resistance plate to be browned is positioned downwards. This allows it to be sprayed with atomized browning liquid by the spraying component 3 below during transport, thus achieving the browning treatment. The browning liquid on the resistance plate falls quickly due to gravity, and the resistance plate can be further rinsed with subsequent browning liquid, ensuring the concentration of browning liquid in contact with the resistance plate and guaranteeing the browning effect. After browning is completed, the resistance plate is swept clean by an air knife 4 to prevent excessive accumulation of browning liquid and subsequent over-browning.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
