Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically to a jet structure, an anode box, and a horizontal electroplating line. Background Technology

[0002] In existing horizontal electroplating lines, an electroplating tank is typically provided. The workpiece to be plated moves horizontally within the electroplating tank. The electroplating tank contains an upper anode box and a lower anode box. The workpiece to be plated acts as the cathode, moving between the upper and lower anode boxes. Anode material is placed in both the upper and lower anode boxes. The electroplating solution filling the electroplating tank connects the anode material and the workpiece to be plated, allowing the cations in the electroplating solution to adhere to the cathode, forming a plating layer.

[0003] To promote the flow of the electroplating solution in the electroplating zone and improve its exchange capacity, a jetting structure is typically installed between the upper and lower anode boxes to spray the electroplating solution onto the upper and lower surfaces of the workpiece, thereby improving the electroplating quality. However, the nozzles in existing jetting structures are generally positioned perpendicular to the workpiece. During the electroplating process, when the workpiece is thin, the electroplating solution sprayed from the nozzles creates jet impact and disturbance, causing the workpiece to fluctuate up and down. This can easily lead to problems such as jamming, misalignment, and breakage, severely affecting the electroplating quality and production. Utility Model Content

[0004] In view of this, the present invention provides a jetting structure to solve the problem that during the electroplating process, when the plate to be plated is a thin plate, the electroplating liquid sprayed from the nozzle causes jetting impact disturbance on the plate to be plated, causing the plate to fluctuate up and down with the jetting impact disturbance, which can easily lead to problems such as plate jamming, plate deviation and breakage, seriously affecting the electroplating quality of the plate to be plated and electroplating production.

[0005] In a first aspect, this utility model provides a jet structure, comprising: Multiple upper spray branch pipes are fixed at intervals on the upper frame. The upper spray branch pipes are arranged in a direction perpendicular to the conveying direction of the plate to be plated. Multiple upper nozzles are provided at intervals on the upper spray branch pipes. The outlet of the upper nozzle of at least one upper spray branch pipe is inclined towards the conveying direction of the plate to be plated. Multiple downward jet branch pipes are fixed at intervals on the lower frame, and the downward jet branch pipes are arranged in a direction perpendicular to the conveying direction of the workpiece to be plated; multiple downward nozzles are spaced apart on the downward jet branch pipes; the outlet of the downward nozzle of at least one downward jet branch pipe is inclined towards the conveying direction of the workpiece to be plated. Beneficial effects: By adopting the above technical solution, and by setting the upper and lower nozzles inclined towards the conveying direction of the workpiece to be plated, the sprayed electroplating liquid can provide a component force for the workpiece to be plated to move along the conveying direction, guiding the movement of the workpiece, reducing the direct frontal impact on the workpiece to be plated, and mitigating the degree of up-and-down fluctuation caused by the jet impact disturbance. This provides a certain guiding effect on the workpiece to be plated, making it more stable when passing between the upper and lower frames, alleviating the problems of plate jamming, plate deviation, and breakage existing in the prior art, and ensuring electroplating production and electroplating quality.

[0006] Optionally, the number of upper and lower spray branch pipes is the same, and they are arranged in a one-to-one correspondence; the one-to-one corresponding upper and lower spray branch pipes are arranged on the same vertical plane. Beneficial effects: By adopting the above technical solution, and symmetrically arranging the upper and lower spray branch pipes, the forces on the upper and lower surfaces of the workpiece to be coated are basically balanced, making the workpiece relatively stable during transport and movement.

[0007] Optionally, the upper jet branch pipe with the inclined upper nozzle is alternately arranged with the upper jet branch pipe without the inclined upper nozzle; correspondingly, the lower jet branch pipe with the inclined lower nozzle is alternately arranged with the lower jet branch pipe without the inclined lower nozzle.

[0008] Optionally, the upper nozzles on the upper spray branch pipe and the lower nozzles on the lower spray branch pipe, located on the same vertical plane, correspond one-to-one and are staggered. Beneficial effect: This application adopts the above technical solution to improve the uniformity of electroplating solution spraying and avoid spray blind spots.

[0009] Optionally, along the conveying direction of the plate to be plated, the upper nozzles on two adjacent upper spray branches are staggered; and along the conveying direction of the plate to be plated, the lower nozzles on two adjacent lower spray branches are staggered. Beneficial effect: This application adopts the above technical solution to improve the uniformity of electroplating solution spraying and avoid spray blind spots.

[0010] Optionally, the number of both the upper jet branch pipe and the lower jet branch pipe is four.

[0011] Optionally, one end of each of the multiple upward jet branch pipes is connected to the upward jet main pipe; one end of each of the multiple downward jet branch pipes is connected to the downward jet main pipe; the upward jet main pipe and the downward jet main pipe are respectively connected to the electroplating solution in the electroplating tank via pipes and a power pump.

[0012] Optionally, the thickness of the plate to be plated ranges from 0.036 mm to 0.15 mm.
