Description

Technical Field

[0001] The present application relates to the technical field of metal surface treatment equipment, and in particular to a plating device for metal materials. Background Art

[0002] Metal plating 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 that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics.

[0003] For example, a Chinese patent document with publication number CN116377546B discloses an electroplating device, including an electroplating tank, a mounting frame is fixedly connected to the vertical outer wall of the electroplating tank, a hanger for placing metal workpieces is provided on the mounting frame, a pulse wheel is rotatably connected to the bottom of the electroplating tank, an air pump is fixedly connected to the fixed plate, an air outlet of the air pump is fixedly connected to an air outlet pipe, a check valve is fixedly connected to the lower end of the air outlet pipe, an L-shaped air duct is fixedly connected to the check valve, and an air blowing pipe connected to the L-shaped air duct is fixedly connected to the electroplating tank. During electroplating, the workpiece to be electroplated is hung on the hanger, the air pump is controlled to run, the check valve is opened, and the air pump conveys high-pressure gas to the L-shaped air duct through the air outlet pipe. The high-pressure gas in the L-shaped air duct is sprayed into the electroplating tank through the air blowing pipe. The sprayed high-pressure gas can drive the metal ions near the anode plate to move quickly toward the workpiece to be electroplated, and the sprayed high-pressure gas can drive the impeller to rotate. The impeller can improve the exchange efficiency between the anode plate and the electroplating solution near the workpiece to be electroplated, and effectively improves the efficiency of the metal ions electrolyzed at the anode to be adsorbed to the workpiece to be electroplated to form a coating.

[0004] In the above-mentioned related technologies, the flow of electroplating liquid will impact the workpiece, causing the workpiece to shake on the hanger, increasing the risk of collision with other workpieces or hangers; in addition, since the workpiece is directly suspended on the hanger during electroplating, the contact position between the workpiece and the hanger cannot be electroplated, which affects the uniformity of the coating and the quality of the workpiece, and reduces the service life of the workpiece.

[0041] Reference Figure 1 and Figure 2 The suspension assembly 1 includes a mounting rod 11 and a clamping rod 12 for mounting the clamping assembly 2. The mounting rod 11 is vertically arranged, and the clamping rod 12 is horizontally arranged. The mounting rod 11 and the clamping rod 12 are fixed by welding. A clamping groove 13 is arranged on the clamping rod 12, and the inner wall of the clamping groove 13 abuts against the cathode frame 03. In this embodiment, an insulating layer is arranged on the surface of the mounting rod 11 and the clamping rod 12, and the inner wall of the clamping groove 13 contacts the cathode frame 03. Then, power can be supplied to the clamping assembly 2, and then the clamped workpiece can be energized.

[0042] Reference Figure 2 and Figure 3 Two clamping assemblies 2 are arranged on the mounting rod 11, and the two clamping assemblies 2 respectively include a fixing sleeve 21 fixed on the mounting rod 11, a clamping rod 22 slidably connected to the fixing sleeve 21, and a clamping spring 23 arranged in the fixing sleeve 21, one end of the clamping spring 23 is fixed on the fixing sleeve 21, and the other end is fixed on the clamping rod 22, and the clamping spring 23 is used to drive the clamping rod 22 to move in the horizontal direction toward the mounting rod 11. In this embodiment, the clamping rod 22 and the mounting rod 11 are arranged vertically; at the same time, a first adjusting assembly 4 is arranged on the mounting rod 11, and the first adjusting assembly 4 is used to drive the two clamping rods 22 away from each other, and is used to abut against the inner wall of the workpiece to achieve clamping and fixing of the workpiece.

[0043] Reference Figures 1 to 3 In order to facilitate the fixing of the workpiece, a clamping plate 24 is fixedly installed at one end of the clamping rod 22 away from the mounting rod 11, and a conductive sheet (not shown in the figure) is arranged at one end of the clamping plate 24 away from the clamping rod 22. The conductive sheet is connected to the inside of the clamping rod 22 through a wire, and the clamping rod 22 is conductively connected through the first adjustment component 4, the mounting rod 11 and the cathode frame 03, so as to facilitate the electrification of the workpiece. In addition, a mounting plate 05 is fixedly installed on the clamping plate 24, and a blocking component 5 for blocking the conductive sheet is arranged on the mounting plate 05. When the conductive sheet on the clamping plate 24 is not in contact with the workpiece, the conductive sheet is blocked by the blocking component 5, and then the metal ions attached to the conductive sheet during electroplating can be reduced.

[0044] Reference Figure 2 and Figure 3 The blocking assembly 5 includes a blocking plate 51 slidably connected to the mounting plate 05 and a blocking spring 52 fixed on the blocking plate 51. One end of the blocking spring 52 is fixed to the mounting plate 05, and the other end is fixed to the blocking plate 51. The blocking spring 52 is used to push the blocking plate 51 to move in the vertical direction away from the clamping rod 12. In this embodiment, one side of the blocking plate 51 abuts against the conductive sheet to reduce exposure of the conductive sheet when not in use, thereby protecting the conductive sheet.

[0045] Reference Figure 2 and Figure 3 The first adjusting component 4 includes a first adjusting screw 41 threadedly connected to the mounting rod 11 and a first conical adjusting block 42 fixed on the first adjusting screw 41. The lower end cross-section of the first conical adjusting block 42 is smaller than the upper end cross-section, and under the action of the clamping spring 23, the end face of the clamping rod 22 abuts against the first conical adjusting block 42. The first adjusting screw 41 rotates, driving the first conical adjusting block 42 to move along the length direction of the mounting rod 11, and then pushes the two clamping rods 22 away from each other, so that the two clamping plates 24 abut against the inner wall of the workpiece, and the clamping spring 23 is in a stretched state, thereby achieving clamping and fixing of the workpiece, and then when improving the fluidity of the electroplating solution, the shaking of the workpiece can be reduced and the quality of electroplating can be improved.

[0046] Reference Figures 2 to 8 Two support assemblies 6 are arranged on the mounting rod 11, and the workpiece is supported by the two support assemblies 6. At the same time, the workpiece is limited by the limit assembly 3. At this time, the clamping assembly 2 and the workpiece are separated, so that the contact position between the workpiece and the clamping plate 24 is convenient for electroplating; the support assembly 6 includes a moving block 61 slidably connected to the mounting rod 11, a support shaft 62 rotatably connected to the moving block 61, and a support plate 63 fixed on the support shaft 62. In this embodiment, the two support plates 63 rotate in opposite directions.

[0047] Reference Figures 2 to 8Two limit assemblies 3 are arranged on the mounting rod 11, and the two limit assemblies 3 respectively include a limit sleeve 31 fixed on the mounting rod 11, a limit rod 32 slidably connected to the limit sleeve 31, and a limit spring 33 arranged in the limit sleeve 31, one end of the limit spring 33 is fixed on the limit sleeve 31, and the other end is fixed on the limit rod 32, the limit rod 32 and the clamping rod 22 are arranged in parallel, the limit spring 33 is used to pull the limit rod 32 to move in the direction close to the mounting rod 11, and at the same time, a second adjusting assembly 8 is arranged on the mounting rod 11, and the second adjusting assembly 8 is used to drive the limit rod 32 to move on the limit sleeve 31, and then the workpiece is limited by the two limit rods 32. In this embodiment, a rubber pad is provided at one end of the limiting rod 32 away from the mounting rod 11. When limiting the workpiece, the rubber pad abuts against the inner wall of the workpiece, which can reduce damage to the plated position of the inner wall of the workpiece. By energizing the workpiece through the support plate 63, the clamping force on the workpiece can be reduced, thereby protecting the workpiece and the plated position.

[0048] Reference Figures 3 to 8 A fixing assembly 7 for fixing the position of the moving block 61 is provided on the second adjusting assembly 8. When the clamping assembly 2 clamps and fixes the workpiece, the fixing assembly 7 fixes the position of the moving block 61. At this time, the support plate 63 is vertically arranged and is inside the workpiece. When the clamping assembly 2 and the workpiece are separated, the fixing assembly 7 no longer fixes the moving block 61. At this time, the support plate 63 abuts against the bottom of the workpiece, and the workpiece is supported by the two support plates 63. Figure 1 With the cooperation of the limit assembly 3, the workpiece can be fixed. At this time, the workpiece is connected to the cathode frame 03 through the support plate 63, which is convenient for powering the workpiece. At this time, metal ions can adhere to the contact position between the clamping plate 24 and the workpiece, and then the workpiece can be plated in all directions to improve the quality of the workpiece.

[0049] Reference Figures 3 to 8The second adjusting assembly 8 includes a second adjusting screw 81 threadedly connected to the mounting rod 11 and a second conical adjusting block 82 fixed on the second adjusting screw 81. The structure of the second conical adjusting block 82 is the same as that of the first conical adjusting block 42. In this embodiment, the second adjusting screw 81 is penetrated by the first adjusting screw 41 and is rotatably connected to the first adjusting screw 41. Under the action of the limit spring 33, the limit rod 32 is pulled to abut against the first conical adjusting block 42. Then, during the rotation of the second adjusting screw 81, the first conical adjusting block 42 can be driven to move. When the first conical adjusting block 42 moves, the two limit rods 32 are pushed away from each other, so that the limit spring 33 is in a stretched state. Then, under the action of the two limit rods 32, the workpiece on the support plate 63 is limited. When the clamping assembly 2 and the workpiece are disengaged, the workpiece can still be fixed by the action of the support plate 63 and the limit rod 32, thereby facilitating the electroplating of the contact position between the workpiece and the clamping plate 24.

[0050] Reference Figures 3 to 8 A pushing assembly 9 is provided on the mounting rod 11. The pushing assembly 9 is used to push the support plate 63 to move in the vertical direction and rotate around the axis of the support shaft 62, and then make the support plate 63 contact the bottom of the workpiece, thereby achieving the purpose of support. In the initial state, the support plate 63 is in a vertical state, and the workpiece is fixed by the clamping assembly 2. When the support plate 63 is needed to support the workpiece, the pushing assembly 9 drives the support plate 63 to move while rotating along the axis of the support shaft 62, and then when the support plate 63 abuts against the bottom of the workpiece, the two clamping plates 24 approach each other. At this time, the contact position between the workpiece and the clamping plate 24 is exposed in the electroplating solution, and then it is easy for metal ions to adhere, so as to achieve the purpose of coating the contact position between the clamping plate 24 and the workpiece.

[0051] Reference Figures 3 to 8, a mounting groove 06 is provided on the mounting rod 11, and the pushing assembly 9 is arranged in the mounting groove 06. At the same time, the moving block 61 is slidably connected in the mounting groove 06. The pushing assembly 9 includes a pushing plate 91 fixed to the inner wall of the mounting groove 06 and a pushing rod 92 fixed on the support shaft 62. The side of the moving block 61 close to the support plate 63 abuts against the surface of the pushing plate 91, and a pushing surface 93 is provided on the pushing plate 91. The pushing surface 93 is inclined in the vertical direction toward the direction close to the support shaft 62, so that the horizontal cross-section of the pushing plate 91 gradually increases in the direction away from the clamping rod 12. In this embodiment, one end of the pushing rod 92 away from the support shaft 62 abuts on the pushing plate 91. When the moving block 61 moves in the direction away from the clamping rod 12, under the action of the pushing surface 93, the support shaft 62 can drive the support plate 63 to rotate, and then it is convenient for the support plate 63 to abut against the bottom of the workpiece to achieve support for the workpiece. A limiting plate 10 is fixed on the side wall of the installation groove 06 , the limiting plate 10 abuts against the pushing plate 91 , and the side surface of the limiting plate 10 and the side wall of the installation groove 06 form a channel for the support shaft 62 to move.

[0052] Reference Figures 3 to 8 The fixing assembly 7 includes a fixing rod 71 fixed on the second adjusting screw 81 and a fixing groove 72 provided on the moving block 61. The fixing groove 72 is set to an arc structure. At the same time, a pulling spring is set on the mounting rod 11. One end of the pulling spring is fixed on the moving block 61, and the other end is fixed on the mounting rod 11. In this embodiment, the height of the fixing groove 72 along the length direction of the mounting rod 11 is greater than the height of the fixing rod 71. When the moving block 61 needs to move, the second adjusting screw 81 rotates to drive the fixing rod 71 to rotate, so that the fixing rod 71 is separated from the fixing groove 72, and then the moving block 61 is pulled to move under the action of the pulling spring. During the movement of the moving block 61, the support plate 63 is pushed to rotate under the action of the pushing surface 93. In order to reduce the moving speed of the moving block 61, a damping rod is set in the mounting groove 06. One end of the damping rod is fixed on the moving block 61, and the other end is fixed on the inner wall of the mounting groove 06, so that the rotation of the support plate 63 can be more stable. In addition, the elastic force of the pulling spring is greater than the gravity of the workpiece. When the support plate 63 abuts against the bottom of the workpiece, the support plate 63 can support the workpiece under the action of the pulling spring, and then the workpiece is limited and fixed with the cooperation of the limiting assembly 3.

[0053] The implementation principle of a metal material plating device in an embodiment of the present application is as follows: when electroplating an annular metal workpiece, the positions of the two clamping plates 24 are adjusted by the first adjusting screw 41, and then the two clamping plates 24 are made to abut against the inner wall of the workpiece, pushing the sealing plate 51 to move away from the workpiece so that the sealing plate 51 abuts against the upper end surface of the workpiece. At this time, the support plate 63 is vertically arranged and is inside the annular metal workpiece, and then the cathode frame 03 is placed in the clamping groove 13. At this time, the workpiece is energized through the conductive sheet, and the workpiece is in the electroplating cell 02. The annular metal workpiece of the cathode is plated by the movement of metal ions in the electrolyte. In other embodiments, the electroplating efficiency can also be increased by increasing the fluidity of the electrolyte.

[0054] After a period of electroplating, the second adjusting screw 81 is rotated, and the second adjusting screw 81 rotates to drive the second conical adjusting block 82 to move, and at the same time drives the fixing rod 71 to move, so that the fixing rod 71 is separated from the fixing groove 72, and then under the action of the pulling spring, the moving block 61 is pulled to move in the installation groove 06, and under the action of the pushing surface 93, the pushing rod 92 is pushed to rotate, so that the pushing rod 92 drives the supporting shaft 62 to rotate, and then the supporting plate 63 moves and rotates at the same time, and finally the supporting plate 63 abuts against the lower end of the workpiece to support the workpiece, and at the same time, the second conical adjusting block 82 will push the limiting rod 32 to move when it moves. The first adjusting screw 41 is then rotated in the opposite direction to make the first conical adjusting block 42 move in the opposite direction. Then, under the action of the clamping spring 23, the clamping plate 24 is driven to move away from the inner wall of the workpiece. Finally, under the action of the blocking spring 52, the blocking plate 51 is pushed to move, and the conductive sheet is blocked by the blocking plate 51 to reduce the conductive sheet from being plated with metal ions. At this time, the workpiece is powered by the support plate 63, and then the contact position between the workpiece and the clamping plate 24 is electroplated, so that the electroplating effect of the workpiece is better and the corrosion resistance of the workpiece is improved.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
