Description

Technical Field

[0001] The present invention relates to the technical field of metal electroplating and its auxiliary equipment, and in particular to a suspension device for batch electroplating and a use method thereof. Background Art

[0002] Metal is a substance with lustrous, ductile, easy to conduct electricity and heat. The above characteristics of metal are related to the free electrons in metal crystals. In nature, most metals exist in a chemical state, and a few metals such as gold, platinum, silver, and bismuth exist in a free state. Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics.

[0003] In the process of metal electroplating, a suspension device is generally required to place the metal suspension into the electroplating tank. In order to improve the electroplating efficiency, most metals are now suspended and electroplated in batches, which can improve the metal electroplating efficiency. For example, the existing public document CN206467317U - A suspension device for hardware electroplating, and the existing public document CN110616453A - A suspension device for electroplating of hardware products, disclose a metal suspension device;

[0004] Although the existing disclosed suspension device for batch electroplating can realize metal suspension, it still has certain shortcomings in actual use: first, the existing suspension device for batch electroplating removes the plating liquid attached to the surface of the workpiece in the previous process by leaving the workpiece stationary and soaking it in distilled water between adjacent electroplating processes, and this method will affect the removal efficiency of the plating liquid on its surface and increase the cleaning time of the plating liquid; secondly, the existing suspension device for batch electroplating directly hangs the hanger on the hanger when in use, or limits the hanger by means of bolt pressure, etc., and this method is cumbersome and complicated for the disassembly and assembly steps of the hanger, which affects the work efficiency and cannot quickly disassemble and assemble the hanger; finally, the existing suspension device for batch electroplating lacks anti-collision measures when in use or cannot make corresponding adjustments according to the size of the workpiece, so collisions between adjacent workpieces may occur during the start or stop of the equipment, affecting the electroplating and product quality of the workpiece; therefore, it is necessary to improve the existing technology to solve the above technical problems. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

[0048] Example 1

[0049] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig.10 , which is the first embodiment of the present invention, provides a suspension device for batch electroplating. The suspension device for batch electroplating introduces gas into the cleaning tank 200 through the fan 401 to make the distilled water continuously roll to act on the surface of the workpiece, thereby accelerating the cleaning efficiency, and driving the sliding block 105 and the hanger 106 to shake continuously, further accelerating the cleaning efficiency.

[0050] Specifically, the workbench 100 has a mobile frame 101 arranged in a horizontal array on the surface of the workbench 100, the interior of the mobile frame 101 is slidably connected to a lifting frame 102, a hanging frame 103 is hung on the surface of the lifting frame 102, a fixed frame 104 is fixedly connected to the bottom of the hanging frame 103, a sliding block 105 is slidably connected to the inner wall of the fixed frame 104, a tooth plate 105a is fixedly connected to the bottom of the sliding block 105, a guide rod 107 is slidably connected to the inner rear of the sliding block 105, and the outer wall of the guide rod 107 is fixedly connected to the inner rear of the sliding block 105. A first spring 108 is sleeved on both sides; a cleaning tank 200, which is located directly in front of the work frame 100; a linkage assembly 300, including a hollow cylinder 301 fixedly connected to the bottom of the fixed frame 104 and an impeller 303 arranged above the inside of the hollow cylinder 301, and a fixed plate 302 is fixedly connected to the top rear end of the hollow cylinder 301; and a pneumatic assembly 400, including a fan 401 installed at the bottom of the work frame 100 and a diverter pipe 402 installed at the air outlet end of the fan 401 through a pipe joint.

[0051] For details, please refer to Figure 4 , Figure 8 , Fig. 9 and Fig.10A first rotating shaft 303a is fixedly connected to the inner wall of the impeller 303, one end of the first rotating shaft 303a penetrates the bearing on the inner wall of the hollow cylinder 301 and the first pulley 303b, the outer wall of the first pulley 303b is connected to the outer wall of the second pulley 304b through a belt, a second rotating shaft 304 is installed at the center of the front end surface of the second pulley 304b, the other end of the second rotating shaft 304 penetrates the bearing on the fixed plate 302 and is connected to the half toothed disc 304a; In the embodiment, a guide plate 301a is fixedly connected to the inner wall of one side of the hollow cylinder 301, and the rack on the outer wall of the half toothed disc 304a meshes with the rack at the bottom of the toothed plate 105a; nozzles 403 are arranged in an array in the horizontal direction on the outer wall of the diverter pipe 402, and a butt-joint pipe 404 is fixedly arranged at the top of the nozzle 403; wherein the top of the butt-joint pipe 404 is inserted into the inner bottom end of the upper adjacent hollow cylinder 301, and air holes 403a are evenly spaced on the outer wall of the nozzle 403;

[0052] When the above arrangement is in use, after the hanger 106 is hung inside the sliding block 105, the position and height of the hanger 103 and the hanger 106 inside are adjusted by the movable frame 101, the lifting frame 102, etc. to complete the relevant electroplating operation. After each electroplating process, the workpiece on the hanger 106 needs to be cleaned with the distilled water in the cleaning tank 200 to clean the electroplating liquid attached to the surface of the workpiece to avoid affecting the subsequent electroplating operation. When cleaning the workpiece, the hanger 106 and the workpiece on its surface are immersed in the cleaning tank 200. At this time, the hollow cylinder 301 moves down with the fixed frame 104 and is inserted into the cleaning tank. The outside of the butt joint 404 in the pool 200 is then turned on to start the fan 401. The air inlet end of the fan 401 is provided with a filtering measure. The fan 401 draws the filtered air in and then flows through the diverter pipe 402 to enter each nozzle 403 respectively. Then the air is discharged from the air hole 403a on the nozzle 403 and the butt joint 404, so that the distilled water can continuously roll on the surface of the workpiece, thereby accelerating the cleaning efficiency of the electroplating liquid on the surface of the workpiece. Among them, the air discharged from the butt joint 404 will blow the impeller 303 in the hollow cylinder 301, and the impeller 303 will be affected by the wind and will rotate with the first rotating shaft 303. a is the center of the circle, and the rotation of the first rotating shaft 303a will drive the first pulley 303b to rotate synchronously, wherein the outer wall of the first pulley 303b is connected to the second pulley 304b through a belt, so when the first pulley 303b rotates, it will drive the second pulley 304b to rotate synchronously under the action of the belt, and the rotation of the second pulley 304b will drive the semi-toothed disc 304a to rotate synchronously under the action of the second rotating shaft 304, wherein the rack on the outer wall of the semi-toothed disc 304a is meshed with the rack at the bottom of the upper toothed plate 105a, so when the semi-toothed disc 304a rotates, it will drive the toothed plate 105a to rotate in the horizontal direction The reciprocating motion causes the sliding block 105 to slide along the outer wall of the guide rod 107 and squeeze the first spring 108 on one side. After the contact limit between the half toothed disc 304a and the toothed plate 105a disappears, the sliding block 105 rebounds under the elastic performance of the first spring 108, and plays a buffering role under the action of the first spring 108 on the other side. Then, the above operation is repeated continuously under the action of the half toothed disc 304a, so that the sliding block 105 drives the hanger 106 to perform a continuous reciprocating motion, and the hanger 106 keeps shaking, which can further improve the cleaning efficiency and effect of the electroplating liquid on the workpiece surface.

[0053] Furthermore, both the movable frame 101 and the lifting frame 102 are driven to move and lift by external devices. This is the prior art, so it will not be elaborated on here. The guide rod 107 further guides and assists the sliding of the sliding block 105. The first spring 108 is provided with two groups, which are respectively located on both sides of the sliding block 105, and play a buffering and rebounding role for the sliding block 105, so that the sliding block 105 can reciprocate. Distilled water for cleaning the electroplating solution is stored in the cleaning tank 200, and the diverter pipe 402 is used for air diversion. The air inlet end of the fan 401 is provided with filtering measures. Only a part of the surface of the semi-toothed disk 304a is provided with a rack to achieve intermittent meshing with the rack on the tooth plate 105a, and the docking pipe 404 can be inserted into the bottom of the hollow cylinder 301.

[0054] Read in detail Figure 3 , Figure 6 and Figure 7 As shown, a mounting groove 105b is provided at the center of the front end surface of the sliding block 105, baffles 105c are fixedly connected above and below the inner walls on both sides of the mounting groove 105b, empty grooves 105d are provided on both sides of the interior of the sliding block 105, and a hanger 106 is hung inside the sliding block 105.

[0055] Furthermore, the baffle 105c is mainly used to block and limit the rotation direction and position of the first rotating plate 501 and the second rotating plate 502.

[0056] Example 2

[0057] Reference Figure 7 , Fig.11 and Fig.12 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that, in order to quickly disassemble and assemble the hanger 106, the hanger 106 is hung inside the mounting groove 105b from bottom to top, and a pressing plate 601 is used to press the top of the hanger 106 to increase the stability of the hanger 106.

[0058] Specifically, it also includes an opening and closing component 500 arranged above and below the inside of the installation groove 105b, and the opening and closing component 500 includes a first rotating plate 501 and a second rotating plate 502 symmetrically arranged at both ends of the inside of the installation groove 105b, and the front and rear ends of the outer walls of the first rotating plate 501 and the second rotating plate 502 are fixedly connected with a fixed block 501a, and a first rotating rod 503 is installed on the inner wall of the fixed block 501a; a first torsion spring 504 is sleeved on the outer wall of the first rotating rod 503, and the two ends of the first rotating rod 503 are respectively rotatably installed in bearings on the adjacent first side plate 505; wherein, one end face of the first side plate 505 is fixedly connected to the inner wall of the installation groove 105b, and the first rotating plate 501 and the second rotating plate 502 are respectively located on the upper surface of the adjacent baffle 105c. ; It also includes a pressing assembly 600 arranged inside the empty slot 105d, the pressing assembly 600 includes a pressing plate 601 movably connected to the inner wall of the mounting slot 105b through a hinge and an airbag 602 installed on the inner wall of the pressing plate 601, a first air pipe 602a is arranged at the bottom of one end surface of the airbag 602, the other end of the first air pipe 602a passes through the outer wall of the empty slot 105d and is connected to the connecting pipe 602b through a pipe joint; the other end of the connecting pipe 602b is connected to the second air pipe 603a through a pipe joint, the other end of the second air pipe 603a is arranged on the outer wall of the cylinder 603, and a lifting plate 604 is installed at the telescopic end of the cylinder 603, and tension springs 605 and second springs 606 are respectively fixed at the four corners of the bottom and top of the lifting plate 604;

[0059] When the above arrangement is in use, when the staff installs or removes the hanger 106, the hook on the hanger 106 is attached to the bottom of the first rotating plate 501 and the second rotating plate 502 located on both sides below, and then force is applied to the hanger 106, so that the first rotating plate 501 and the second rotating plate 502 are subjected to force and rotate with the first rotating rod 503 as the center of the circle, and the first torsion spring 504 is squeezed. At this time, after the hook on the top of the hanger 106 moves into the interior of the installation groove 105b, it will squeeze the pressure plates 601 on both sides of the interior of the installation groove 105b. After the pressure plates 601 are subjected to force The airbag 602 will be squeezed, and the gas in the airbag 602 will enter the cylinder 603 through the first air pipe 602a, the connecting pipe 602b and the second air pipe 603a. The gas filled in the cylinder 603 will extend and push the lifting plate 604 to move, and will stretch the tension spring 605 and squeeze the second spring 606. Then, as the top hook of the hanger 106 moves into the installation groove 105b, at this time, the first rotating plate 501 and the second rotating plate 502 below the installation groove 105b are no longer stressed, and the two will be in the first torsion spring 5 04, the first rotating plate 501 and the second rotating plate 502 are rebounded to the initial position, and then the force on the hanger 106 is stopped, and then the hanger 106 is hung on the surface of the first rotating plate 501 and the second rotating plate 502, and then the force on the bottom of the pressure plate 601 disappears. At this time, the lifting plate 604 is pressed back to the initial position under the elastic performance of the tension spring 605 and the second spring 606, and the gas in the cylinder 603 returns to the inside of the airbag 602, and the airbag 602 expands to push the pressure plate 601 to press on the hanger 1 06 top hook surface, thereby increasing the stability of the hanger 106 after placement, reducing the swing amplitude and probability of the hanger 106, and when the hanger 106 needs to be removed, force is applied to the hanger 106 to move it up again, and squeeze and push the upper two side pressure plates 601 and the first rotating plate 501 and the second rotating plate 502 located above, so that the hanger 106 can be installed and removed from bottom to top. When the staff removes the hanger 106, the lifting height of the hanger 106 can be reduced compared to the traditional hanging method, reducing labor intensity, saving time and effort.

[0060] Furthermore, the opening and closing assembly 500 is provided with two groups. The first rotating plate 501 and the second rotating plate 502 will rotate with the first rotating rod 503 as the center when subjected to force, and in conjunction with the first torsion spring 504, the first rotating plate 501 and the second rotating plate 502 can return to their initial positions. The air in the airbag 602 and the cylinder 603 can flow under the action of the first air pipe 602a, the connecting pipe 602b and the second air pipe 603a. Under the action of the elastic properties of the tension spring 605 and the second spring 606, the airbag 602 is in an expanded state for a long time when not subjected to external force and pushes the pressing plate 601 to press the top of the hanger 106.
