Description

Technical Field

[0001] The invention relates to the technical field of electroplating, in particular to a tool for chemical plating and a chemical plating method. Background Art

[0002] The electroplating process is a process in which metal ions in the solution are deposited on the surface of the cathode plated part in a circuit composed of an electrolyte, a cathode and an anode under the action of a DC electric field. The general chemical plating process includes the following steps: polishing, polishing, hanging, degreasing, washing, electrolytic polishing or chemical polishing, pickling and activation, pre-plating, electroplating, washing, post-treatment, washing, drying, hanging, inspection and packaging.

[0003] During the degreasing, pickling, washing and electroplating processes of chemical plating, the plated parts need to be placed in a solution for treatment. For plated parts with an inner cavity, in order to ensure that the plated parts can discharge the solution in their inner cavity after each process, as described in the text of the Chinese patent number CN109628985B, which is named as the box electroplating rotary tooling, the box electroplating rotary tooling rotates the box fixing seat on the main frame, and the rotation axis is horizontal. After installation, the opening of the inner cavity of the workpiece can be rotated in a vertical plane, which can ensure that the inner cavity opening of the workpiece faces upward during electroplating, and the inner cavity opening can be downward after the workpiece is rotated in the light emitting process, so that the liquid can be discharged in time.

[0004] However, in actual implementation, since the tooling described in the cited patent needs to fix the plated parts, when such tooling is used for plating a large number of small and medium-sized parts such as shafts with blind holes, transition sleeves (large holes at both ends and small holes in the middle) or pipe caps, it is necessary to set a fixing structure for each plated part, which obviously leads to low processing efficiency. In addition, during the process of fixing such tooling to the plated parts, the contact points with the plated parts often have the problem of incomplete contact with the solution, which affects the final chemical plating effect of the plated parts, and therefore needs to be solved urgently. Summary of the invention

[0005] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides a chemical plating tool and a chemical plating method, which can efficiently and high-quality perform chemical plating degreasing, pickling, water washing, and electroplating processes on a large number of small plated parts.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A tool for chemical plating, comprising a cleaning basket and a small basket frame arranged in the cleaning basket, wherein a trough structure with a V-shaped cross section is formed on the upper part of the small basket frame, and the trough structure serves as a storage trough for storing shaft-shaped plated parts; and also comprising a swing mechanism, with two side walls of the cleaning basket located in the length direction of the storage trough as connecting side walls, the swing mechanism comprising two connecting parts movably connected to the two connecting side walls of the cleaning basket, both of which can perform reciprocating lifting and lowering motions, and the two connecting parts move in opposite directions, so that the cleaning basket performs up and down swinging motions on the vertical plane where the length direction of the storage trough is located.

[0008] As a further solution of the present invention: the swing mechanism includes a horizontal axis that is rotatably engaged on the mounting seat and driven by a third motor, the horizontal axis is distributed along the length direction of the storage slot, and both ends of the horizontal axis are fixed with rocker rods that are radially distributed along the horizontal axis, and the cantilever ends of the two rocker rods extend in opposite directions to each other; the upper parts of the two connecting parts are respectively rotatably engaged on the cantilever ends of the two rocker rods, and the upper rotation axis of the connecting parts is distributed parallel to the horizontal axis.

[0009] As a further solution of the present invention: the connecting part is a hook, which includes an upper rod part and a lower hook part. The upper rod part constitutes the upper part of the connecting part and rotates with the cantilever end of the swing arm, and the lower hook part is used to hook the connecting side wall to form the movable connection.

[0010] As a further solution of the present invention: the small basket frame is detachably connected to the cleaning basket, and the small basket frame is arranged in at least two layers which are sequentially distributed up and down.

[0011] As a further solution of the present invention: it also includes a lifting mechanism, a rotating mechanism is installed on the lifting part of the lifting mechanism, the rotating part of the rotating mechanism performs reciprocating rotation around the vertical axis, and the rotating part is connected to the swinging mechanism to drive the swinging mechanism to produce reciprocating rotation around the vertical axis.

[0012] As a further solution of the present invention: the lifting mechanism includes a slide rail installed on a fixed frame and distributed vertically, and a lifting seat constituting the lifting part is slidably connected to the slide rail. A first motor is also installed on the fixed frame, and the output shaft of the first motor is distributed horizontally, and the output shaft of the first motor is dynamically connected to the lifting seat through a crank-connecting rod mechanism.

[0013] As a further solution of the present invention: the rotating mechanism includes a rotating rod rotatably engaged on the lifting seat, the rotating rod is vertically distributed, and the rotating part is composed of the rotating rod; a second motor is also installed on the lifting seat, the output shaft of the second motor is vertically distributed, and the output shaft of the second motor is dynamically connected to the rotating part through a crank rocker mechanism.

[0014] As a further solution of the present invention: the lifting mechanism is installed on a crane, and the crane is used for transporting the tooling between different chemical plating processes.

[0015] A chemical plating method, wherein a chemical plating tool is used to perform degreasing, pickling, water washing and electroplating processes in chemical plating, and the method comprises the following steps:

[0016] S1, place the shaft-shaped plated parts in the storage groove on the cleaning basket along the length direction of the storage groove, and the openings of all the shaft-shaped plated parts are facing the same side; place the sheet-shaped plated parts in the cleaning basket at random;

[0017] S2, the swing mechanism drives the cleaning basket to tilt toward the first side, and the tilting direction of the cleaning basket is parallel to the vertical plane where the length direction of the storage tank is located. At this time, the shaft-shaped plating member forms a water storage state with the opening tilted upward, and then the cleaning basket is moved into the solution tank;

[0018] S3, the lifting mechanism, the rotating mechanism and the swinging mechanism are all started, so that the cleaning basket performs a composite motion of reciprocating lifting and lowering in the solution tank, reciprocating rotation around the vertical axis, and up and down swinging on the vertical plane where the storage tank is located in the long direction of the tank;

[0019] S4. Move the cleaning basket outside the solution tank, and the swing mechanism drives the cleaning basket to tilt toward the second side, and the tilting direction of the cleaning basket is parallel to the vertical plane where the length direction of the storage tank is located. At this time, the shaft-shaped plated parts form a drainage state with the opening inclined downward, and after the drainage is completed, the shaft-shaped plated parts and the sheet-shaped plated parts are taken out, or the cleaning basket is transferred to the next process.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The storage tank in the cleaning basket is used to store the shaft-shaped plated parts. When a large number of shaft-shaped plated parts are subjected to chemical plating, the plated parts only need to be placed as needed, thereby improving the efficiency of the plated parts in the chemical plating process. In addition, a swing mechanism is provided that can drive the cleaning basket to swing up and down on the vertical plane where the storage tank is located in the long direction, so that the open end of the plated parts is rotated to tilt upward before the plated parts enter the solution tank, so that the plated parts can be vented upward through the open end when entering the tank, so that the solution can stably enter the inner cavity of the plated parts, and prevent the problem of incomplete degreasing, pickling, and washing of the plated parts due to air traps. At the same time, since the plated parts do not need to be clamped and fixed, when the cleaning basket swings up and down, the plated parts will be suspended for a short time. At the same time, the contact between the plated parts and the small basket frame will also be displaced due to shaking, so as to ensure that the plated parts can be in full contact with the solution, thereby improving the chemical plating effect on the plated parts.

[0022] 2. The small basket frame is detachably connected to the cleaning basket, and the small basket frame is arranged in at least two layers distributed in sequence from top to bottom. By disassembling the small basket frame of the lower layer or all the small basket frames, the cleaning basket of the present invention can also be used for small and micro metallized ceramic substrates, multi-layer ceramic shells, thin sheets, washers and other plated parts. Such plated parts can be placed at will in the lower part of the cleaning basket. When the cleaning basket swings up and down, the plated parts will be suspended briefly. At the same time, the contact point between the plated parts and the small basket frame will also be displaced due to shaking, so as to ensure that the plated parts can be in full contact with the solution, thereby improving the versatility of the present invention.

[0023] 3. While the cleaning basket is swinging up and down on the vertical plane where the storage tank is located in the long direction, the cleaning basket can also perform a composite motion of reciprocating lifting and reciprocating rotation around the vertical axis. This composite motion will make the plated parts hang in the air for a longer time; at the same time, the contact between the plated parts and the small basket frame will also be more thoroughly replaced due to the shaking, further ensuring that the plated parts can be in full contact with the solution, thereby improving the chemical plating effect on the plated parts. At the same time, the reciprocating rotation of the cleaning basket around the vertical axis also causes the solution in the inner cavity of the plated parts to be thrown out under the action of centrifugal force during the reciprocating rotation of the cleaning basket, and the solution in the solution cavity is sucked in again under the action of negative pressure, thereby improving the chemical plating effect on the inner cavity of the plated parts.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] For ease of understanding, the specific structure and working mode of the present invention are further described below in conjunction with the accompanying drawings:

[0034] The specific structure of the present invention refers to Figure 1-7 As shown, its main structure includes a cleaning basket 50, a swing mechanism 40 for driving the cleaning basket 50 to swing in a vertical plane, a rotating mechanism 30 for driving the cleaning basket 50 to rotate around a vertical axis, and a lifting mechanism 20 for driving the cleaning basket 50 to lift and lower.

[0035] Specifically, Figure 2 As shown, a small basket frame 51 is provided in the cleaning basket 50, and a groove structure with a V-shaped cross section is formed on the upper part of the small basket frame 51, and the groove structure serves as a storage groove 52 for storing the shaft-shaped plated parts. Figure 1As shown, the two side walls of the cleaning basket 50 located in the direction of the length of the storage tank 52 are used as connecting side walls, and the swing mechanism 40 includes two connecting parts that are movably connected to the two connecting side walls of the cleaning basket 50, and the two connecting parts can perform reciprocating lifting and lowering movements, and the two connecting parts move in opposite directions, so that the cleaning basket 50 can perform up and down swinging movements on the vertical plane where the length of the storage tank 52 is located. When in use, the axially axially of the plated part is placed in the storage tank 52 along the length of the storage tank 52, and the open ends of all the axially axially plated parts are facing the same side. Thereafter, one connecting part performs an upward movement, and the other performs a downward movement, so that the side of the cleaning basket 50 adjacent to the open end of the axially axially plated part is tilted upward. Afterwards, the tooling of the present invention or the solution tank is moved so that the cleaning basket 50 is placed in the solution of the solution tank. During this process, since the open end of the plated part is tilted upward, it is convenient for the plated part to be vented upward through the open end when entering the tank, so that the solution can stably enter the inner cavity of the plated part, preventing the problem of incomplete degreasing, pickling and water washing of the plated part due to air trapping. After that, the two connecting parts perform reciprocating lifting and lowering motions in opposite directions respectively, so that the cleaning basket 50 performs an up-and-down swinging motion on the vertical plane where the storage tank 52 is located in the long direction of the tank. In this process, since the shaft-shaped plated parts are placed in the storage tank 52, when a large number of shaft-shaped plated parts are subjected to chemical plating, it is only necessary to place the plated parts as needed, thereby improving the efficiency of the plated parts in the chemical plating process; in addition, since the plated parts do not need to be clamped and fixed, when the cleaning basket 50 performs an up-and-down swinging motion, the plated parts will be suspended for a short time, and at the same time, the contact point between the plated parts and the small basket frame 51 will also be shifted due to shaking, so as to ensure that the plated parts can be in full contact with the solution, thereby improving the chemical plating effect on the plated parts. Finally, after the plated parts are processed in the solution tank, the cleaning basket 50 is separated from the solution tank, and the side of the cleaning basket 50 adjacent to the opening end of the plated parts is tilted downward, so that the solution in the plated parts can be discharged outward, thereby ensuring that the residual solution in the inner cavity of the plated parts can be discharged outward stably.

[0036] On the basis of the above, if Figure 1As shown, the swing mechanism 40 includes a horizontal shaft 43 that is rotatably matched on the mounting seat 41 and driven by a third motor 42. The third motor 42 drives the horizontal shaft 43 to rotate, and a transmission structure such as a gearbox, belt or gear in the prior art can be used. This is the prior art and will not be further described in the present invention. The horizontal shaft 43 is distributed along the length direction of the storage slot 52. Both ends of the horizontal shaft 43 are fixed with swing rods 44 that are radially distributed along the horizontal shaft 43, and the cantilever ends of the two swing rods 44 extend in opposite directions to each other. Therefore, when the horizontal shaft 43 rotates, the cantilever ends of the two swing rods 44 will rotate upward and downward respectively; in addition, since the upper parts of the two connecting parts are rotatably matched on the cantilever ends of the two swing rods 44 respectively, and the upper rotation axis of the connecting part is parallel to the horizontal shaft 43, when the horizontal shaft 43 rotates, the two connecting parts will be driven to do a reciprocating lifting motion of one rising and one falling. In this embodiment, a power source is used to drive the horizontal shaft 43 to rotate, so that the two connecting parts can be made to do a reciprocating lifting motion of one rising and one falling. Compared with two power sources driving the connecting parts to move separately, it not only reduces the cost but also ensures that the movement coordination of the two connecting parts is stable and error-free. As mentioned above, the driving of the connecting parts can be carried out by two power sources separately, such as setting two vertically distributed linear power sources, which can be cylinders or electric cylinders, and the power end of the linear power source is movably connected to the connecting part. By using the cooperation of the two linear power sources, the two connecting parts can also be driven to do a reciprocating lifting motion of one rising and one falling.

[0037] Further, such as Figure 1 As shown, the connection part is a hook 45, and the hook 45 includes an upper rod and a lower hook. The upper rod constitutes the upper part of the connection part and is rotatably matched with the swing rod 44, and the lower hook is used to hook the connecting side wall to form a movable connection. The hook 45 connection method is used to facilitate the disassembly and assembly of the cleaning basket 50, which effectively improves the convenience of disassembly and assembly of the cleaning basket 50. In actual implementation, the connection part can also be in the form of a crank connecting rod or a pull rope.

[0038] In addition, if Figure 2 As shown, the small basket frame 51 is detachably connected to the cleaning basket 50, and the small basket frame 51 is arranged in at least two layers distributed in sequence from top to bottom. By disassembling the small basket frame 51 of the lower layer or all the small basket frames 51, the cleaning basket 50 of the present invention can also be used for small and micro metallized ceramic substrates, multi-layer ceramic shells, thin sheets, washers and other plated parts. Such plated parts can be placed at will in the lower part of the cleaning basket 50. When the cleaning basket 50 swings up and down, the plated parts will be suspended briefly. At the same time, the contact point between the plated parts and the small basket frame 51 will also be displaced due to shaking, so as to ensure that the plated parts can be in full contact with the solution, thereby improving the versatility of the present invention.

[0039] It is worth mentioning that Figure 3-7As shown, the present invention also includes a lifting mechanism 20, and a rotating mechanism 30 is installed on the lifting part of the lifting mechanism 20; the rotating part of the rotating mechanism 30 performs a reciprocating rotation around the vertical axis, and the rotating part is connected to the swing mechanism 40 to drive the swing mechanism 40 to produce a reciprocating rotation around the vertical axis. In this embodiment, combined with the above-mentioned swing mechanism 40, the cleaning basket 50 can perform a composite motion of lifting and reciprocating rotation around the vertical axis while performing an up and down swinging motion on the vertical plane where the storage tank 52 is located in the long direction of the tank. This composite motion will make the plated parts hang in the air for a longer time. At the same time, the contact between the plated parts and the small basket frame 51 will also be more thoroughly replaced due to the shaking, further ensuring that the plated parts can be in full contact with the solution, thereby improving the chemical plating effect on the plated parts. At the same time, the reciprocating rotation of the cleaning basket 50 around the vertical axis causes the solution in the inner cavity of the plated part to be thrown out under the action of centrifugal force during the reciprocating rotation of the cleaning basket 50, and the solution in the solution cavity is sucked back under the action of negative pressure, thereby improving the chemical plating effect on the inner cavity of the plated part.

[0040] Specifically, Figure 4 As shown, the lifting mechanism 20 includes a slide rail 11 installed on the fixed frame 10 and distributed in a vertical manner, and a lifting seat 23 constituting a lifting part is slidably connected to the slide rail 11. A first motor 21 is also installed on the fixed frame 10, and the output shaft of the first motor 21 is horizontally distributed, and the output shaft of the first motor 21 is connected to the lifting seat 23 through a crank connecting rod mechanism 22. The crank connecting rod mechanism 22 is used to drive the lifting seat 23 to move up and down, and the first motor 21 only needs to rotate continuously. Compared with the form of driving the lifting by the cylinder or the screw slider mechanism, there is no need to set a program to make the pump machine that executes the cylinder extension and reciprocating air intake and air suction and the motor that executes the screw slider mechanism forward and reverse rotation, so that the lifting action of the lifting mechanism 20 is stable and efficient.

[0041] Specifically, Figure 4 and Figure 5 As shown, the rotating mechanism 30 includes a rotating rod 31 rotatably matched on the lifting seat 23, the rotating rod 31 is vertically distributed, and the rotating part is formed by the rotating rod 31; the lifting seat 23 is also equipped with a second motor 32, the output shaft of the second motor 32 is vertically distributed, and the output shaft of the second motor 32 is connected to the rotating part through a crank rocker mechanism 33. The crank rocker mechanism 33 is used to drive the rotating rod 31 to reciprocate, and the second motor 32 only needs to rotate continuously. Compared with directly driving the rotating rod 31 to reciprocate through a servo motor, not only the cost is reduced, but also the failure rate of the device is effectively reduced.

[0042] On the basis of the above, if Figure 7As shown, the lifting mechanism 20 is installed on a crane 60, which is used for the transportation of tooling between different chemical plating processes, thereby eliminating the need to set the tooling described in the present invention in the chemical plating degreasing, pickling, water washing, electroplating and other processes, thereby effectively reducing the overall cost of the chemical plating process.

[0043] It is worth mentioning that the present invention also provides a chemical plating method, which uses a chemical plating tool to perform degreasing, pickling, water washing and electroplating processes in chemical plating, including the following steps:

[0044] S1, place the shaft-shaped plated parts in the storage groove 52 on the cleaning basket 50 along the length direction of the storage groove 52, and the openings of all the shaft-shaped plated parts are facing the same side; place the sheet-shaped plated parts randomly in the cleaning basket 50;

[0045] S2, the swing mechanism 40 drives the cleaning basket 50 to tilt toward the first side, and the tilting direction of the cleaning basket 50 is parallel to the vertical plane where the length direction of the storage tank 52 is located. At this time, the shaft-shaped plating member forms a water storage state with the opening tilted upward, and then the cleaning basket 50 is moved into the solution tank;

[0046] S3, the lifting mechanism 20, the rotating mechanism 30 and the swinging mechanism 40 are all started, so that the cleaning basket 50 performs a composite motion of reciprocating lifting and lowering in the solution tank, reciprocating rotation around the vertical axis, and up and down swinging on the vertical plane where the storage tank 52 is located in the long direction of the tank;

[0047] S4. Move the cleaning basket 50 outside the solution tank, and the swing mechanism 40 drives the cleaning basket 50 to tilt toward the second side, and the tilting direction of the cleaning basket 50 is parallel to the vertical plane where the length direction of the storage tank 52 is located. At this time, the axial plating parts form a drainage state with the opening inclined downward, and after the drainage is completed, the axial plating parts and the sheet-shaped plating parts are taken out, or the cleaning basket 50 is transported to the next process.

[0048] In the above four steps:

[0049] Step S1 is the material discharge process, which serves the subsequent steps S2-S4.

[0050] Step S2 is the stage of placing the plated parts into the slot. In this stage, due to step S1, the axial plated parts are placed in the storage slot 52 on the cleaning basket 50 along the slot length direction of the storage slot 52, and the openings of all the axial plated parts are facing the same side; therefore, when the plated parts enter the slot, all the axial plated parts can form a water storage state with the openings tilted upward. The tilted upward opening ensures that the solution enters the solution and discharges the gas through the openings of the axial plated parts, thereby preventing the problem of incomplete degreasing, pickling and water washing of the plated parts due to air trapping.

[0051] Step S3 is the processing stage. This composite motion can effectively improve the chemical plating effect of the inner cavity of the plated part.

[0052] Step S4 is the stage of draining the plated parts from the tank, which can drain the plated parts after they are processed in the treatment stage, so that the plated parts are drained cleanly without residue after they are taken out of the tank, thereby ensuring that there are no watermarks after the subsequent wind shearing and drying of the plated parts.

[0053] In the above-mentioned steps S2 and S4, Figure 1 The viewing angle is the viewing angle, and the first side and the second side are the left side and the right side, respectively. In addition, in the state where the shaft-shaped plated component forms an opening obliquely upward to store water and in the state where the shaft-shaped plated component forms an opening obliquely downward to drain water, the oblique upward and oblique downward inclination angles are preferably 15° to 30°, which can ensure good water inflow and drainage in the inner cavity of the plated component, and can also ensure stable exhaust during the water inflow process in the inner cavity of the plated component.

[0054] Of course, it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numerals in the claims should not be regarded as limiting the claims involved.

[0055] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

At this time, the shaft-shaped plating member forms a water storage state with the opening tilted upward, and then the cleaning basket (50) is moved into the solution tank; S3, the lifting mechanism (20), the rotating mechanism (30) and the swinging mechanism (40) are all started, so that the cleaning basket (50) performs a composite motion combining reciprocating lifting and lowering in the solution tank, reciprocating rotation around the vertical axis, and up and down swinging on the vertical plane where the storage tank (52) is located in the longitudinal direction of the tank; S4. Move the cleaning basket (50) outside the solution tank, and the swing mechanism (40) drives the cleaning basket (50) to tilt toward the second side, and the tilting direction of the cleaning basket (50) is parallel to the vertical plane where the length direction of the storage tank (52) is located. At this time, the axial plated parts form a drainage state with the opening inclined downward, and after the drainage is completed, the axial plated parts and the sheet plated parts are taken out, or the cleaning basket (50) is transported to the next process.
