Description

Technical Field

[0001] The present invention relates to the field of electroplating, and more particularly to an electroplating device and an electroplating process. Background Art

[0002] Electroplating equipment is mainly used to apply a layer of metal coating on the metal surface to enhance its corrosion resistance, wear resistance and improve appearance. The electroplating process includes multiple steps, which involve specific equipment and tools. The electroplating tank is the core equipment of electroplating, which is usually made of plastic or stainless steel and contains the electroplating solution. The current will pass through the solution in the electroplating tank, so that the coating adheres to the surface of the object to be plated. The power supply can provide a stable current and is an indispensable equipment in the electroplating process. In the traditional electroplating process, the workpiece needs to be clamped, but the contact position between the clamp and the workpiece cannot release the electroplating solution during clamping, resulting in the inability to electroplate the workpiece without dead angles. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides an electroplating device and an electroplating process, which have the beneficial effect of being able to replace the position of clamping the workpiece so that every position on the workpiece can be electroplated.

[0006] A convex plate is fixed on one of the sliders, a motor seat is fixed on the upper center of the cross, a motor is fixed on the motor seat, a screw rod 1 is fixed on the output shaft of the motor, and the screw rod 1 is matched with the convex plate through threads.

[0007] A plurality of arc-shaped pressing sheets are arranged on the inner side of the clamping strip from top to bottom.

[0008] A convex column is fixed to the middle part of the upper side of each clamping strip. The loop wire is soft and connected to four convex columns. A wire is connected to one of the convex columns, and the middle part of the wire is bonded to one end of the cross.

[0030] like Figure 4-5 As shown, this example can achieve the effect of preventing the clamping position from being unable to be electroplated.

[0031] Since the electroplating equipment includes a cross 101, the four ends of the cross 101 are slidably connected with sliders 107, a hinged rod 102 is arranged between two adjacent sliders 107, the hinged rod 102 is hingedly connected to the corresponding slider 107, and a clamping strip 105 is welded on the lower side of each slider 107, so that the four hinged rods 102 form a rectangular connecting rod mechanism, and when the front and rear sliders 107 move away from each other, the left and right sliders 107 will move closer, so that the left and right clamping strips 105 and the front and rear clamping strips 105 can alternately clamp the workpiece to be electroplated to avoid the clamping position being unable to be electroplated.

[0032] like Figure 4-5 As shown, this example can achieve the effect of driving the four sliders 107 to move closer and farther alternately.

[0033] Since a convex plate 202 is fixed on one of the sliders 107, a motor seat 201 is welded to the upper center of the cross 101, a motor is connected to the motor seat 201, a screw 203 is connected to the output shaft of the motor, and the screw 203 and the convex plate 202 are threadedly matched. The motor drives the screw 203 to rotate, thereby driving the convex plate 202 and one of the sliders 107 to slide left and right, thereby driving the four sliders 107 to alternately approach and move away.

[0034] like Figure 4-5 As shown, this example can achieve the effect of avoiding damage to the workpiece during clamping.

[0035] Since a plurality of arc-shaped pressing pieces 106 are arranged on the inner side of the clamping strip 105 from top to bottom, the clamping strip 105 is elastically clamped by the plurality of arc-shaped pressing pieces 106 when clamping the workpiece to avoid damage to the workpiece, and the arc-shaped pressing pieces 106 are made of metal and can conduct electricity.

[0036] like Figure 4-5 As shown, this example can achieve the effect of conducting electricity to the workpiece when two of the clamping bars 105 clamp the workpiece.

[0037] Since a protruding column 104 is welded to the middle of the upper side of each clamping bar 105, the loop wire 103 is soft, and the loop wire 103 is connected to four protruding columns 104, one of the protruding columns 104 is connected to a wire 108, and the middle of the wire 108 is bonded to one end of the cross 101. After the wire 108 is energized, the wire is connected to the four protruding columns 104 through the loop wire 103, and then the wire is connected to the four clamping bars 105. When two of the clamping bars 105 clamp the workpiece, they can conduct electricity to the workpiece, which is convenient for energizing the workpiece.

[0038] like Figure 4-5 As shown, this example can achieve the effect of preventing the wire 108 from being energized to the workpiece without being connected.

[0039] Since the center of the cross 101 is vertically slidably connected with a pressure fork 204, the pressure fork 204 is driven to slide by a hydraulic cylinder, and a terminal 1 205 is welded on the upper part of the pressure fork 204. When the wire 108 is not connected to the workpiece, the pressure fork 204 is driven to move downward to contact the workpiece, and then the pressure fork 204 and the workpiece are energized through the terminal 1 205 to avoid the wire 108 not connecting to the workpiece.

[0040] like Figure 4-6 As shown, this example can achieve the effect of conveniently replacing different clamping strips 105 to clamp the workpiece.

[0041] Since the right end of the cross 101 is connected to the fixed seat 303 by screws, the fixed seat 303 is vertically slidably connected with an L-shaped frame 302, the L-shaped frame 302 is driven to slide by a hydraulic cylinder, and the lower end of the L-shaped frame 302 is connected to the grid 301 by screws, and the grid 301 is located below the multiple clamps 105. When the clamps 105 need to be replaced to clamp the workpiece, the L-shaped frame 302 is lifted to drive the grid 301 to be lifted, and then the workpiece is supported by the grid 301, and then the clamps 105 are replaced to clamp the workpiece, and then the grid 301 is driven to move downward away from the workpiece, so as to facilitate the replacement of different clamps 105 to clamp the workpiece.

[0042] like Figure 7-8 As shown, this example can achieve the effect of driving the workpiece into the electroplating solution or taking it out of the electroplating solution.

[0043] Since the electroplating equipment further comprises a seat block 406, a gantry 401 is vertically slidably connected to the seat block 406, a motor is connected to the gantry 401 by screws, a screw rod 2 405 is connected to the output shaft of the motor, the screw rod 2 405 is matched with the seat block 406 by threads, the fixed seat 303 is fixed to the lower left part of the gantry 401, two connecting columns 404 are welded to the rear side of the seat block 406, a slot 403 is welded between the rear ends of the two connecting columns 404, and two fastening screws 402 are threadedly connected to the slot 403. The slot 403 can be hung on the edge of the electroplating tank, and then the two fastening screws 402 are rotated to press on the electroplating tank, thereby fixing the slot 403 on the electroplating tank, and then the motor drives the screw rod 2 405 to rotate, which can drive the gantry 401 to rise and fall, thereby driving the cross 101 to rise and fall, thereby driving the workpiece to rise and fall, thereby driving the workpiece to enter the electroplating solution or take it out of the electroplating solution.

[0044] like Figure 4-10 As shown, this example can achieve the effect of rapid dissolution of the soluble metal 504 .

[0045] Since the right lower end of the gantry 401 is connected to the strip seat 501 by screws, a second terminal 503 is fixed on the strip seat 501, and a dissolved metal 504 is welded to the lower end of the second terminal 503. A plurality of vertical grooves 505 are arranged in a ring shape on the dissolved metal 504. The second terminal 503 is used to connect the positive electrode of the power supply, so that the dissolved metal 504 enters the solution and is electroplated on the workpiece. The plurality of vertical grooves 505 on the dissolved metal 504 increase its own surface area, thereby facilitating the rapid dissolution of the dissolved metal 504.

[0046] like Figure 9-10 As shown, this example can achieve the effect of preventing the bubbles in the plurality of vertical grooves 505 from affecting the dissolution of the dissolved metal 504 .

[0047] Since the bar seat 501 is vertically slidably connected with a hand rod 502, the lower end of the hand rod 502 is connected with a collar 507 by a screw, and the upper side of the collar 507 is annularly bonded with multiple scrapers 506 made of plastic material, the multiple scrapers 506 are respectively located in the multiple vertical grooves 505, and the multiple scrapers 506 are respectively pressed toward the multiple vertical grooves 505, which can drive the hand rod 502 to slide vertically on the bar seat 501, and then drive the collar 507 to move up and down, and then drive the multiple scrapers 506 to move vertically in the multiple vertical grooves 505, thereby avoiding the presence of bubbles in the multiple vertical grooves 505 affecting the dissolution of the dissolved metal 504.

[0049] S1: clamping the workpiece to be electroplated between two of the clamping bars 105;

[0050] S2: inserting the dissolved metal 504 and the electroplated part into the electroplating solution;
