Abstract

This utility model discloses a jet-stirring composite electroplating device, relating to the field of electroplating equipment technology. It includes a support frame and an electroplating tank, with the electroplating tank fixedly installed on the top of the support frame. An internal guiding mechanism is provided within the electroplating tank, comprising a positioning frame and a guide plate. The guide plate is rotatably installed inside the positioning frame. By setting up the guiding mechanism, an electric cylinder drives a transmission plate to slide along a limiting plate. The transmission plate, through a strip-shaped hole, drives a connecting rod to rotate the guide plate around the positioning frame, achieving precise and flexible adjustment of the electroplating solution flow direction. This effectively improves the distribution of the electroplating solution within the electroplating tank, enhancing the thickness consistency and surface quality of the electroplated layer. Combined with a stirring component fixed by the positioning rod, a composite stirring mode combining jetting and stirring is formed, preventing electroplating solution deposition and further improving the uniformity of the electroplating solution concentration.

Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to a jet stirring composite electroplating device. Background Technology

[0002] In the electroplating production process, the accuracy of the flow direction control of the electroplating solution directly affects the uniformity of the electroplated layer.

[0003] However, in the existing technology, the flow direction of the electroplating solution in the electroplating device is mostly unidirectional, which cannot be flexibly adjusted according to the actual operation requirements. This results in uneven distribution of the electroplating solution in the electroplating tank, with some areas having excessively fast or slow flow rates. Consequently, problems such as inconsistent electroplating layer thickness and poor surface finish are caused on the workpiece surface, which seriously affect the quality stability of the electroplated products.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting a guiding mechanism, the electric cylinder drives the transmission plate to slide along the limiting plate.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a jet stirring composite electroplating device, including a support frame 1 and an electroplating tank 2. The electroplating tank 2 is fixedly installed on the top of the support frame 1. A guide mechanism 3 is provided inside the electroplating tank 2. The guide mechanism 3 includes a positioning frame 31 and a flow guide plate 32. The flow guide plate 32 is rotatably installed inside the positioning frame 31. The positioning frame 31 is fixedly installed at the end of the electroplating tank 2. A transmission plate 35 is provided on one side of the positioning frame 31. A connecting rod 36 is fixedly installed at the end of the flow guide plate 32. The connecting rod 36 is slidably connected inside the transmission plate 35. A strip hole 37 is opened at the junction of the transmission plate 35 and the connecting rod 36. An electric cylinder 34 is rotatably installed at the edge of the electroplating tank 2. One end of the piston rod of the electric cylinder 34 is rotatably connected to the transmission plate 35. A limit plate 33 is fixedly installed on the upper surface of the positioning frame 31. The transmission plate 35 is slidably installed inside the limit plate 33.

[0019] The specific setup and function of this embodiment are described below. The support frame 1 provides a stable installation base for the electroplating tank 2. The positioning frame 31 fixed at the end of the electroplating tank 2 provides installation support for the guide mechanism 3. The guide plate 32, which is rotatably installed inside the positioning frame 31, can adjust the flow direction of the electroplating solution. The connecting rod 36 at the end of the guide plate 32 passes through the slot 37 of the transmission plate 35 to achieve a sliding connection. The limiting plate 33 on the upper surface of the positioning frame 31 forms a sliding limit on the transmission plate 35. After the electric cylinder 34, which is rotatably installed at the edge of the electroplating tank 2, is started, its piston rod pushes the transmission plate 35 to slide stably along the limiting plate 33. The transmission plate 35 drives the connecting rod 36 to move synchronously through the slot 37, thereby driving the guide plate 32 to rotate around the positioning frame 31 to accurately adjust the guiding angle, making the electroplating solution flow more evenly, improving the thickness consistency and surface quality of the electroplating layer. The overall structure of the device is compact and easy to operate, greatly improving the efficiency and reliability of the electroplating operation.

[0020] Example 2: Figure 1 , Figure 2 and Figure 3As shown, a delivery pump 4 is provided on one side of the support frame 1, and a collection tank 7 is provided at the bottom of the support frame 1. A return pipe 5 is connected between one of the collection tanks 7 and the input end of the delivery pump 4. A delivery pipe 6 is connected to the output end of the delivery pump 4. The delivery pipe 6 is connected to one side of the end of the electroplating tank 2. A positioning rod 8 is fixedly installed on the inner wall of the electroplating tank 2. A stirring assembly 9 is fixedly installed on the upper surface of the positioning rod 8. The positioning rod 8 is located above the collection tank 7, and the axis of the stirring assembly 9 coincides with the axis of the outlet of the collection tank 7.

[0021] The overall effect of this embodiment is as follows: the delivery pump 4 is connected to the bottom collection tank 7 through the return pipe 5. After the collection tank 7 collects the electroplating solution flowing out of the electroplating tank 2, it is transported to the input end of the delivery pump 4 through the return pipe 5. The delivery pump 4 pressurizes and delivers the electroplating solution to one side of the end of the electroplating tank 2 through the delivery pipe 6 at the output end, forming a stable jet. Guided by the guide plate 32, the jet is shot onto the surface of the material. The positioning rod 8 is located above the collection tank 7. The stirring component 9 operates synchronously during the circulation of the electroplating solution, stirring the electroplating solution returning to the electroplating tank 2. The support frame 1 provides a stable installation foundation for the delivery pump 4 and the collection tank 7. The return pipe 5 and the delivery pipe 6 form a closed-loop circulation channel, which, together with the delivery pump 4, achieves efficient circulation of the electroplating solution, avoids electroplating solution deposition, and allows the stirring to cover the core area of ​​the electroplating solution return. The jet and stirring work together to form a compound stirring effect, which greatly improves the uniformity of the electroplating solution concentration and ensures the stability and continuity of the electroplating solution circulation.

[0022] The usage method and working principle of this device are as follows: First, add electroplating solution to the electroplating tank 2, then put the material into the tank, then turn on the transfer pump 4, the collecting tank 7 collects the electroplating solution flowing out of the electroplating tank 2, and transports it to the transfer pump 4 through the return pipe 5. The transfer pump 4 pressurizes and transports the electroplating solution to the electroplating tank 2 through the transfer pipe 6 to form a jet. Then, start the electric cylinder 34, whose piston rod pushes the transmission plate 35 to slide along the limiting plate 33. The transmission plate 35 drives the connecting rod 36 through the strip hole 37, which in turn drives the guide plate 32 to rotate around the positioning frame 31 to adjust the guide angle. At the same time, start the stirring component 9 to make it operate synchronously to stir the return electroplating solution until the electroplating operation is completed and then turn off all components.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
