Description

Technical Field

[0001] The utility model relates to the technical field of electroplating tanks, in particular to an electroplating tank. Background Art

[0002] The electroplating tank for printing the plated parts usually uses an air compressor to directly spray high-pressure, impurity-free air into the tank liquid through an air jet pipe group connected to the bottom of the tank, so that bubbles pass through the liquid layer in clusters. The entrainment and turbulent pulsation of the jet flow promote the rapid uniformity of the tank liquid temperature and concentration.

[0003] Current electroplating tanks, such as those with publication number CN105019006B, are described as being used for electroplating panels. The tank comprises a body for holding a plating solution, multiple conduits, and multiple nozzles. The panels to be plated are housed within the body, with the conduits disposed on either side of the body. The nozzles are arranged in rows along the conduits. The plating solution flows within the conduits and is ejected through the nozzles. Each row of nozzles directs the flow toward the panel to be plated, with the angle between the nozzles and the panel being plated being 40-50 degrees.

[0004] During the use of the above-mentioned device, the electroplating guide rail enters the electroplating tank along the bottom of the electroplating tank, and the workpiece is electroplated by using a nozzle that sprays obliquely upward. When it comes to long workpieces, it is difficult to evenly electroplate the upper part of the workpiece; therefore, we propose an electroplating tank to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the present utility model is to provide an electroplating tank to solve the problem that in the use of the existing device proposed in the above background technology, the electroplating guide rail enters the tank along the bottom of the electroplating tank, and the workpiece is electroplated by using a nozzle that sprays obliquely upward. When it comes to long workpieces, it is difficult to evenly electroplate the upper part of the workpiece.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a plating tank, comprising an electroplating tank body, a filter pump outlet pipe is arranged below the front end of the electroplating tank body, a diverter pipe is installed at one end of the filter pump outlet pipe, a T-shaped manifold is arranged between the two branches of the diverter pipe, an injection pipe is installed at the upper end of the T-shaped manifold, and the injection pipe extends to the interior of the electroplating tank body, a spray main pipe is installed at the upper end of the diverter pipe, and one end of the spray main pipe extends to the rear end of the electroplating tank body, the rear end of the spray main pipe is connected to the electroplating tank body through a positioning bracket, a spray branch pipe is installed at the lower end of the spray main pipe, six spray branches are provided, and the six spray branches are equidistantly distributed, and a nozzle is provided on the outer wall of the spray branch pipe, and a plurality of nozzles are provided.

[0007] Preferably, cathode rack supports are installed at the front and rear ends above the electroplating tank body, cathode hangers are installed between the cathode rack supports, and an anode plate support is installed on one side inside the electroplating tank body, and two anode plate supports are provided, and an anode plate is installed between the two anode plate supports.

[0008] Preferably, a positioning hole is provided inside the cathode frame support.

[0009] Preferably, valves are installed on the branches of the diverter pipe and the T-shaped manifold.

[0010] Preferably, a pressure measuring branch pipe is installed on the outer wall of the shunt pipe, and a pressure sensor is installed at one end of the pressure measuring branch pipe.

[0011] Preferably, a filter recovery pipe is provided at the rear end of the electroplating tank body, and one end of the filter recovery pipe extends to the interior of the electroplating tank body, and the other ends of the filter recovery pipe and the filter pump out pipe are both connected to the electroplating liquid filter.

[0012] Preferably, a base is installed below the electroplating tank body, and shock-absorbing feet are installed at the four corners of the lower end of the base.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model can pump the plating liquid from the plating liquid filter to the filter pump outlet pipe, so that the plating liquid enters the spray main pipe on both sides of the workpiece along the diversion pipe, and is sprayed out through the nozzles on the multiple spray branch pipes vertically arranged at the lower end of the spray main pipe, so as to spray and electroplate the two sides of the workpiece. Because the spray main pipe enters from the top of the plating tank and extends vertically downward to form multiple spray branch pipes, it can achieve uniform electroplating of the upper and lower ranges of the workpiece, solving the problem that in the existing device, the plating guide rail enters the tank along the bottom of the plating tank during use, and the workpiece is sprayed with the electroplating nozzle sprayed obliquely upward to perform the electroplating spray operation, which makes it difficult to uniformly electroplate the upper part of the workpiece when targeting long workpieces.

[0015] 2. When the workpiece is large and needs immersion electroplating, the valve on the electroplating tank diversion pipe can be closed, and the T-shaped manifold branch valve can be opened to quickly inject the electroplating liquid into the main body of the electroplating tank along the injection pipe to facilitate the immersion electroplating of the workpiece and increase the diversity of electroplating methods.
