Description

Technical Field

[0001] This utility model relates to the field of metal electroplating technology, and in particular to an adjustable metal electroplating anode protection device. Background Technology

[0002] Metal electroplating is a process that deposits a metal coating on the surface of metal products through electrolysis. It can improve their corrosion resistance, wear resistance, and aesthetics, and is widely used in manufacturing and other fields.

[0003] Metal electroplating is the process of depositing a metal coating on the surface of metal products. The electroplating process usually requires an anode. As an important part of the electroplating process, the anode undergoes an oxidation reaction under the action of direct current, replenishing the electroplating solution with metal ions to form a uniform and dense coating. However, the anode is affected by corrosion from the electroplating solution, uneven current distribution, and surface passivation during use, thus requiring protection. Metal electroplating anode protection devices can provide physical isolation, adjust current density, and activate the surface, thereby extending the service life of the anode.

[0004] However, existing metal electroplating anode protection devices have the following shortcomings:

[0005] In the existing technology, the anode protection device for metal electroplating is usually fixed in a specific position in the electroplating tank. Since the metals are diverse in shape and size, the fixed anode cannot be adjusted in position and distribution according to the actual situation of the metals, resulting in uneven current distribution and differences in current density in different parts of the metals. This leads to inconsistent plating thickness, affects the electroplating quality, and reduces the corrosion resistance and aesthetics of the product.

[0006] Therefore, we propose an adjustable metal electroplating anode protection device to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide an adjustable metal electroplating anode protection device. It utilizes a motor drive combined with a threaded transmission mechanism to tightly fit the outer shells of two containers. With the help of the motor drive and gear transmission, the clamped pressure container can be rotated. At the same time, by rotating the threaded rod driven by the motor, the position of the welding head can be flexibly adjusted, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable metal electroplating anode protection device, comprising an adjustment mechanism, wherein a protection mechanism is fixedly connected to the bottom of the adjustment mechanism;

[0009] The adjustment mechanism includes a fixed frame, a groove on one side of the outer wall of the fixed frame, a slider slidably embedded in the inner surface of the groove, a support column fixedly connected to one side of the outer wall of the slider, a telescopic column movably inserted into the inner surface of the support column, a push plate fixedly connected to the top of the telescopic column, an electric push rod fixedly connected to one side of the outer wall of the push plate, a mounting frame fixedly connected to the bottom of the telescopic column, a mounting hole on the top of the mounting frame, a second bearing fixedly inserted into the inner surface of the mounting hole, a rotating shaft fixedly inserted into the inner surface of the second bearing, and a second motor fixedly connected to the top of the rotating shaft.

[0010] Preferably, the inner surface of the slider is threaded with a threaded rod, the top of the threaded rod is fixedly connected to a first motor, and the outer surface of the threaded rod is fixedly sleeved with two first bearings, and the outer surface of the two first bearings is fixedly inserted into the inside of the fixed frame.

[0011] Preferably, the protective mechanism includes a protective cover, and a connecting frame is fixedly connected to the top of the protective cover.

[0012] Preferably, an anode plate is placed at the bottom of the inner wall of the protective cover, and a threaded groove is formed on one side of the outer wall of the protective cover.

[0013] Preferably, an adjusting screw is threadedly connected to the inner surface of the threaded groove, and a knob is fixedly connected to one side of the outer wall of the adjusting screw.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, by cooperating with the adjustment mechanism and the protection mechanism, and using a motor drive combined with a threaded transmission mechanism, the anode assembly is precisely displaced in the vertical direction. The synergistic effect of the electric push rod and the telescopic assembly allows for flexible adjustment of the distance between the anode assemblies. In addition, the rotation of the motor-driven shaft can adjust the angle of the anode assembly. This comprehensive adjustment mechanism ensures that the anode and the workpiece surface maintain a suitable distance and angle, thereby optimizing the electric field distribution, promoting the uniform deposition of the electroplating layer on the workpiece surface, and thus improving the electroplating quality and enhancing the corrosion resistance and aesthetics of the product.

[0024] 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.

[0025] 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.

[0026] Example 1, as shown in the attached document Figure 1 - Appendix Figure 4 As shown, this utility model provides a technical solution: an adjustable metal electroplating anode protection device, including an adjustment mechanism 1, and a protection mechanism 2 fixedly connected to the bottom of the adjustment mechanism 1;

[0027] The adjustment mechanism 1 includes a fixed frame 101. A groove 102 is provided on one side of the outer wall of the fixed frame 101. A slider 103 is slidably embedded in the inner surface of the groove 102. A support column 107 is fixedly connected to one side of the outer wall of the slider 103. A telescopic column 108 is movably inserted into the inner surface of the support column 107. A push plate 109 is fixedly connected to the top of the telescopic column 108. An electric push rod 110 is fixedly connected to one side of the outer wall of the push plate 109. A mounting frame 111 is fixedly connected to the bottom of the telescopic column 108. The top of the mounting frame 111... A mounting hole 112 is provided, and a second bearing 113 is fixedly inserted into the inner wall of the mounting hole 112. A rotating shaft 114 is fixedly inserted into the inner wall of the second bearing 113. A second motor 115 is fixedly connected to the top of the rotating shaft 114. A threaded rod 104 is threadedly connected to the inner wall of the slider 103. A first motor 105 is fixedly connected to the top of the threaded rod 104. Two first bearings 106 are fixedly sleeved on the outer wall of the threaded rod 104, and the outer walls of the two first bearings 106 are fixedly inserted into the inside of the fixing frame 101.

[0028] The overall effect of Embodiment 1 is as follows: During metal electroplating operations, the height, horizontal distance, and tilt angle of the anode can be flexibly adjusted according to the different shapes and sizes of the metal parts to meet different electroplating process requirements. When it is necessary to adjust the anode height, the first motor 105 is started, and the output end of the first motor 105 drives the threaded rod 104 to rotate. Under the action of threaded transmission, the threaded rod 104 drives the slider 103 to make vertical displacement within the slide groove 102. The movement of the slider 103 further drives the support column 107 and the anode assembly to move synchronously in the vertical direction, thereby accurately realizing the adjustment of the anode assembly height. In terms of adjusting the anode horizontal distance, the electric push rod 110 is started, and the telescopic end of the electric push rod 110 pushes the telescopic column 108 to move linearly in the horizontal direction. This causes the connected anode assembly to shift horizontally, thus controlling the horizontal distance of the anode assembly. To adjust the anode angle, the second motor 115 is activated. The output of the second motor 115 drives the rotating shaft 114 to rotate, which in turn drives the anode assembly to rotate around its axis, thereby changing the tilt angle of the anode assembly. Through the precise adjustment mechanism of height, horizontal distance, and angle, it is possible to ensure that the anode and the workpiece surface always maintain a suitable relative position, optimize the electric field distribution in the electroplating tank, and make the electric field uniformly cover the workpiece surface. In this way, metal ions in the electroplating solution can migrate and deposit evenly on the surface of the metal workpiece under the action of the electric field, ultimately forming a uniform and stable electroplating layer on the workpiece surface, effectively improving the quality and effect of the electroplating process.

[0029] Example 2, as Figure 2-4As shown, the protective mechanism 2 includes a protective cover 201, a connecting frame 202 fixedly connected to the top of the protective cover 201, an anode plate 203 placed at the bottom of the inner wall of the protective cover 201, a threaded groove 204 opened on one side of the outer wall of the protective cover 201, an adjusting screw 205 threadedly connected to the inner surface of the threaded groove 204, a knob 206 fixedly connected to one side of the outer wall of the adjusting screw 205, a third bearing 207 fixedly sleeved on the outer wall of the adjusting screw 205, a clamping plate 208 fixedly sleeved on the outer wall of the third bearing 207, and the bottom of the rotating shaft 114 fixedly connected to the top of the connecting frame 202.

[0030] The overall effect of Embodiment 2 is as follows: During use, the protective cover 201 can provide all-round protection for the anode plate 203, effectively avoiding mechanical collisions that may occur during electroplating, extending the service life of the anode plate 203, and ensuring the continuous and stable operation of electroplating. When it is necessary to fix the anode plate 203, the operator only needs to turn the knob 206. The knob 206 drives the adjusting screw 205 to rotate. Through the threaded engagement between the adjusting screw 205 and the threaded groove 204, when the adjusting screw 205 rotates, according to the thread transmission principle, the adjusting screw... The adjusting screw 205 can move smoothly in the horizontal direction. The movement of the adjusting screw 205 will drive the clamping plate 208 to move synchronously, thereby making the clamping plate 208 apply a stable clamping force to the anode plate 203 and firmly fix the anode plate 203. This stable fixing method ensures that the anode remains stable throughout the entire electroplating process and will not loosen or shift. The stability of the anode can ensure the stability of the electric field distribution during the electroplating process, so that the metal ions in the electroplating solution can be uniformly deposited on the metal surface, thereby improving the electroplating quality and ensuring the uniformity and density of the coating.

[0031] The working principle of the entire device is as follows: First, securely install the device on top of the electroplating tank, ensuring effective connection with the entire electroplating system. Then, the operator manually rotates knob 206. Knob 206 drives the adjusting screw 205 to rotate synchronously. Because the outer wall of the adjusting screw 205 and the inner wall of the threaded groove 204 are connected by threads, rotating the adjusting screw 205, according to the principle of threaded transmission, will cause precise horizontal displacement. The adjusting screw 205 will then further push... The moving clamping plate 208 moves, applying a uniform and stable clamping force to the anode plate 203, thereby firmly fixing the anode plate 203. After fixing the anode plate 203, the position and angle of the anode assembly need to be finely adjusted according to the specific shape and size of the metal parts to be plated. When adjusting the height of the anode assembly, the first motor 105 is started first. The output shaft of the first motor 105 generates rotational power, driving the threaded rod 104 to rotate at high speed. Since the outer wall of the threaded rod 104 is threadedly connected to the inner wall of the slider 103... Therefore, the rotation of the threaded rod 104 drives the slider 103 to move smoothly within the groove 102. The slider 103 then drives the support column 107 and the anode assembly to rise and fall synchronously in the vertical direction, precisely adjusting the height of the anode assembly to suit the electroplating needs of hardware parts of different heights. When it is necessary to adjust the horizontal distance of the anode assembly, the electric push rod 110 is activated first. The telescopic end of the electric push rod 110 drives the telescopic column 108 to move linearly in the horizontal direction. The telescopic column 108 is connected to the anode assembly, thereby adjusting the horizontal position of the anode assembly to ensure that the anode and the hardware parts maintain a suitable distance in the horizontal direction, optimizing the electric field distribution during the electroplating process. If the angle of the anode assembly needs to be changed, the second motor 115 is activated. The output end of the second motor 115 drives the rotating shaft 114 to rotate. The rotating shaft 114 then drives the anode assembly to rotate around the axis of the rotating shaft 114, realizing the flexible change of the anode assembly angle to meet the special requirements of different shaped hardware parts for the anode angle, ensuring that the electroplating layer can be uniformly deposited on the surface of the hardware parts, and improving the electroplating quality.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present 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 the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
