DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0017] like Figures 1 to 6 As shown, a rotary drum type valve stem electroplating device of the present invention comprises a material storage barrel 1, a rotary drum 2 and a plating material 3, wherein the material storage barrel 1 is used to store the electroplating solution, the rotary drum 2 is rotatably installed in the material storage barrel 1, and the outer wall of the rotary drum 2 is densely covered with holes, the plating material 3 is located in the middle of the rotary drum 2, the rotary drum 2 is connected to the negative pole of the power supply, the plating material 3 is connected to the positive pole of the power supply, and a plurality of baffles 4 are arranged on the inner wall of the material storage barrel 1; The baffle 4 is located between the storage barrel 1 and the rotating barrel 2 , and the liquid level of the electroplating solution stored in the storage barrel 1 is higher than the top of the rotating barrel 2 .

[0018] In detail, the openings of the storage barrel 1 and the rotating drum 2 are both facing upward, and the electroplating solution stored in the storage barrel 1 can flow into the rotating drum 2 through the multiple holes on the rotating drum 2, thereby filling the rotating drum 2 with the electroplating solution, and the liquid level of the electroplating solution is higher than the top of the rotating drum 2, and the baffle 4 in the storage barrel 1 is mainly used to hinder the flow of the electroplating solution, that is, when the rotating drum 2 rotates, since the solution inside and outside the rotating drum 2 can communicate through the top area of ​​the rotating drum 2, the baffle 4 can be used to hinder the solution, so that the flow rate of the solution inside the rotating drum 2 is reduced, thereby causing the rotating drum 2 and the solution inside it to produce relative movement, that is, the rotating drum 2 cannot drive the solution to rotate synchronously, and the solution hinders the valve stem in the rotating drum 2 that moves synchronously with the rotating drum 2, so that the valve stem can roll on the inner wall of the rotating drum 2, thereby realizing indirect blocking movement of the valve stem, and combined with the characteristics of water, the valve stem can roll on the inner wall of the rotating drum 2.

[0019] When in use, the positive pole of the power supply is connected to the plating material 3, and the negative pole of the power supply is connected to the drum 2. A large number of valve stems are placed in the drum 2, and the drum 2 cannot be filled with too many valve stems. The drum 2 is rotated, and the drum 2 will drive the valve stems to rotate synchronously. Due to the centrifugal effect, the valve stems are gathered near the inner wall of the drum 2. At the same time, due to the obstruction of the baffle 4 to the solution, the solution also obstructs the valve stem, so that the valve stem cannot move at the same speed as the drum 2. The valve stem rolls on the inner wall of the drum 2, and as a whole, the valve stem moves in a circular motion around the axis of the storage barrel 1. Since the drum 2 and the plating material 3 are energized, the valve stem contacts the drum 2, so the valve stem is also energized. The metal ions separated from the plating material 3 are attached to the surface of the valve stem on the inner wall of the drum 2 through the solution, thereby realizing the electroplating work, and since the valve stem is in a tumbling motion state, the metal ions can be attached to the surface of the valve stem, thereby realizing comprehensive electroplating work, and this method can avoid mutual shielding between the valve stems, thereby achieving the working effect of simultaneously processing a large number of valve stems.

[0020] The new equipment allows multiple valve stems to be processed at the same time. The design of the rotating drum allows a large number of valve stems to be electroplated at one time, which greatly improves processing efficiency and shortens production cycles. Since the valve stems inside the rotating drum are constantly rolling during the electroplating process, this helps to ensure that all surfaces of each valve stem can be evenly exposed to the electroplating solution, thereby ensuring the uniformity of the coating. The design takes into account the prevention of mutual shielding between valve stems, so that each valve stem can effectively receive the current required for electroplating, avoiding the problem of incomplete electroplating or uneven coating caused by shielding. Compared with the traditional single processing method, the rotating drum design simplifies The operation process is simplified, the need for manual intervention is reduced, and the possibility of human error is reduced; by using the baffle 4 to block the flow of solution, the solution also hinders the movement of the valve stem, so that the friction between the rotating drum 2 and the valve stem is utilized to enable the valve stem to roll, which can avoid the valve stem and the rotating drum 2 being in a relatively static state, thereby realizing dynamic electroplating of the valve stem; in short, this rotary drum valve stem electroplating equipment solves the problems of low efficiency and uneven plating in traditional electroplating methods through innovative design, and provides a more advanced and efficient surface treatment solution for the valve manufacturing industry.

[0021] Furthermore, a movable tray 5 is arranged in the rotating drum 2, and the movable tray 5 slides vertically along the axis of the rotating drum 2. A plurality of guide edges are arranged on the circumferential outer wall of the movable tray 5, and a plurality of guide grooves are opened on the circumferential inner wall of the rotating drum 2, and the guide grooves are slidably installed in the guide edges.

[0022] In detail, during electroplating, the valve stem can be placed on the movable tray 5. Due to the setting of the guide edges and the guide grooves, the rotating drum 2 and the movable tray 5 can rotate synchronously, that is, the rotation of the rotating drum 2 can be achieved by rotating the movable tray 5, so that the movable tray 5 and the rotating drum 2 can drive the valve stem to move synchronously.

[0023] When the electroplating is completed, in order to facilitate the removal of the valve stem, the movable tray 5 can be lifted so that the movable tray 5 can drive the valve stem to move upward. In actual use, the movable tray 5 can only drive the valve stem to a position close to the liquid surface, but cannot completely move the movable tray 5 out of the rotating drum 2 to prevent the valve stem from falling between the storage barrel 1 and the rotating drum 2. If the valve stem needs to be completely moved out of the solution, it is necessary to reduce the storage volume of the solution in the storage barrel 1 to lower the height of the solution level. Of course, the thickness of the movable tray 5 can also be increased. When the top of the movable tray 5 is moved out of the solution, the liquid level will also drop because part of the movable tray 5 no longer occupies the volume of the solution.

[0024] Furthermore, a column 6 is vertically arranged in the middle of the movable tray 5, one end of the column 6 passes through the movable tray 5 and the rotating drum 2, and the column 6 is fixedly connected to the movable tray 5, and the column 6 is slidably connected to the rotating drum 2, and a support platform 7 is arranged at the other end of the column 6, and a conductive column 8 is fixed on the support platform 7, and the plating material 3 is in the shape of a sleeve, and the plating material 3 is sleeved on the conductive column 8, and the plating material 3 and the conductive column 8 are locked by a limiting collar 9; The conductive column 8 is connected to the negative pole of the power supply, and the support platform 7 and the limiting ring 9 are both made of insulating materials.

[0025] In detail, the support table 7 and the conductive column 8 can carry the plating material 3, the limiting ring 9 can lock the position of the plating material 3, so as to fix the plating material 3, and the negative pole of the power supply can be connected to the plating material 3 by connecting with the conductive column 8. When the column 6 rotates, it can drive the rotating drum 2 to rotate through the movable tray 5. When the column 6 moves up and down, it can drive the movable tray 5 to move synchronously, and the movement of the column 6 can drive the plating material 3 to move synchronously, so as to facilitate the removal of the plating material 3 from the liquid surface and its replacement.

[0026] Furthermore, a rotating sleeve 11 is provided at the bottom of the storage barrel 1, and the rotating sleeve 11 passes through the storage barrel 1 and rotates relatively, and the shape of the column 6 is polygonal, and the column 6 slides through the rotating sleeve 11; A base 10 for supporting the material storage barrel 1 is disposed at the bottom of the material storage barrel 1 , a first regulating motor 13 is disposed on the base 10 , a transmission wheel 12 is disposed at the output end of the first regulating motor 13 , and the transmission wheel 12 is transmission-connected to the rotating sleeve 11 .

[0027] In detail, since the column 6 needs to rotate and move up and down on the storage barrel 1, it is necessary to use the rotating sleeve 11 to realize the connection between the column 6 and the storage barrel 1. The base 10 can support the storage barrel 1 and the first adjusting motor 13. The first adjusting motor 13 can drive the transmission wheel 12 to rotate, and the transmission wheel 12 drives the rotating sleeve 11 and the column 6 to rotate, thereby driving the movable tray 5 and the rotating drum 2 to rotate. When the column 6 moves up and down, the column 6 and the rotating sleeve 11 slide relative to each other. Therefore, the polygonal shape of the column 6 and the matching relationship between the column 6 and the rotating sleeve 11 are the key points to realize the multiple motion modes of the rotating drum 2 and the movable tray 5.

[0028] Furthermore, a movable plate 14 is provided at the bottom of the column 6, and the column 6 and the movable plate 14 rotate relative to each other, a plug plate 15 is provided at the bottom of the storage barrel 1, the plug plate 15 passes through the movable plate 14 and slides relatively, a second adjusting motor 16 is fixed on the base 10, a threaded rod 17 is provided at the output end of the second adjusting motor 16, a threaded sleeve 18 is screwed on the threaded rod 17, and the threaded sleeve 18 is fixedly mounted on the movable plate 14.

[0029] In detail, the movable plate 14 and the plug plate 15 can play a guiding and supporting role for the column 6, and the second adjusting motor 16, the threaded rod 17 and the threaded sleeve 18 can provide power for the up and down movement of the column 6, that is, when the second adjusting motor 16 is running, it can push the threaded sleeve 18 to move up and down through the threaded rod 17, and the threaded sleeve 18 will drive the column 6 to move up and down through the movable plate 14, and the movable plate 14 slides on the plug plate 15.

[0030] Furthermore, the threaded sleeve 18 is made of insulating material, the bottom of the conductive column 8 passes through the support platform 7 and the column 6 and is electrically connected to the moving plate 14, and the moving plate 14 is electrically connected to the plug plate 15; The bottom of the storage barrel 1 is provided with a notch, a connector is arranged in the notch, and the bottom of the outer wall of the rotating drum 2 is provided with a sealing ring 28, the sealing ring 28 covers the notch, and the connector is electrically connected to the sealing ring 28; A power-on unit is provided between the plug board 15 and the connector, and the power-on unit is used to control whether the plug board 15 is connected to the negative pole or the positive pole of the power source and whether the connector is connected to the positive pole or the negative pole of the power source.

[0031] In detail, since the column 6 and the drum 2 are both in motion, in order to facilitate circuit connection, it is necessary to use the plug board 15 and the connector to achieve static circuit connection. Since the drum 2 is located on the inner wall of the storage barrel 1, in order to energize the drum 2, it is necessary to open a notch at the bottom of the storage barrel 1 so as to connect it to the drum 2 through a connector. The sealing ring 28 can block the notch to prevent the solution from flowing out through the notch, thereby ensuring the smooth connection between the drum 2 and the connector.

[0032] The setting of the power-on unit can connect the plug board 15 and the connector to the power supply, so that the drum 2 and the plating material 3 are energized by the power supply. When the electroplating is working normally, the drum 2 is connected to the negative electrode of the power supply, and the plating material 3 is connected to the positive electrode of the power supply. The plating material 3 releases metal ions and the volume of the plating material 3 gradually decreases. Since the drum 2 is connected to the negative electrode, the metal ions can also adhere to the surface of the drum 2. When the electroplating is completed, the positive and negative electrodes of the drum 2 and the plating material 3 can be swapped, that is, the drum 2 is connected to the positive electrode and the plating material 3 is connected to the negative electrode. At this time, the metal ions on the surface of the drum 2 may be re-aggregated on the plating material 3, thereby avoiding the gradual increase in the surface thickness of the drum 2 and affecting the normal conduction of the current, and facilitating the full recovery and utilization of the metal ions, thereby realizing the reverse electroplating working process. In actual use, the drum 2 is made of titanium, stainless steel, platinum, inert metal alloys, graphite and other materials to prevent it from releasing metal ions and being damaged.

[0033] Further, the power supply unit includes a conductive plate 19 fixed to the bottom of the storage barrel 1, the conductive plate 19 is electrically connected to the connector, a cylinder 20 and an adjustment seat 21 are arranged between the conductive plate 19 and the plug plate 15, the cylinder 20 is fixed to the bottom of the storage barrel 1, the movable end of the cylinder 20 is connected to the adjustment seat 21, the adjustment seat 21 is slidably installed at the bottom of the storage barrel 1, and the connection direction of the plug plate 15 and the conductive plate 19 is perpendicular to the sliding direction of the adjustment seat 21; Two conductive groups are arranged on the adjustment seat 21, and the conductive groups include a terminal 22, a first conductive sheet 23 and a second conductive sheet 24. The terminal 22 is connected to a power source, the terminal 22 is electrically connected to the first conductive sheet 23, and the second conductive sheet 24 in one conductive group is electrically connected to the first conductive sheet 23 in another conductive group. The first conductive sheet 23 and the second conductive sheet 24 in the conductive group are located on the same side of the adjustment seat 21.

[0034] In detail, the two terminals 22 in the two conductive groups can be connected to the positive and negative electrodes of the power supply. There is no mandatory requirement for whether one terminal 22 is specifically connected to the positive or negative electrode of the power supply. One conductive group on the adjustment seat 21 is located on the side of the adjustment seat 21 close to the plug board 15, and the other conductive group is located on the side of the adjustment seat 21 close to the conductive plate 19. The two first conductive sheets 23 in the two conductive groups correspond to each other, and the two second conductive sheets 24 correspond to each other. The cylinder 20 can drive the adjustment seat 21 to move, thereby driving the two conductive groups to move. When the two second conductive sheets on the adjustment seat 21 are When the conductive sheet 24 contacts the plug plate 15 and the conductive plate 19 respectively, the plug plate 15 is connected to the negative pole of the power supply, and the conductive plate 19 is connected to the positive pole of the power supply, that is, the drum 2 is connected to the negative pole, and the plating material 3 is connected to the positive pole. When the adjustment seat 21 moves, the two first conductive sheets 23 contact the plug plate 15 and the conductive plate 19 respectively, the drum 2 is connected to the positive pole, and the plating material 3 is connected to the negative pole. When the first conductive sheet 23 and the second conductive sheet 24 in the conductive group are not in contact with the plug plate 15 or the conductive plate 19, the drum 2 and the plating material 3 are in a power-off state, thereby achieving the working effect of controlling the electrodes of the drum 2 and the plating material 3.

[0035] Furthermore, the connector includes a rotating post 26 rotatably installed in the slot, an elastic metal ring 25 is sleeved on the outer side of the rotating post 26, the rotating post 26 and the elastic metal ring 25 are connected by a plurality of elastic support sheets 27, and the conductive plate 19 is electrically connected to the rotating post 26.

[0036] In detail, since the drum 2 and the sealing ring 28 can rotate, the sealing ring 28 can drive the rotating column 26 to rotate through the elastic metal ring 25, thereby reducing the friction between the elastic metal ring 25 and the sealing ring 28, and since the elastic metal ring 25 and the elastic supporting sheet 27 are both elastic, when the elastic metal ring 25 contacts the sealing ring 28, the top of the elastic metal ring 25 can be deformed and transformed from an arc to a plane, thereby achieving a surface contact effect between the elastic metal ring 25 and the sealing ring 28, and this effect has no effect on the rotation of the elastic metal ring 25 and the rotating column 26, and the elastic supporting sheet 27 provides elastic support for the elastic metal ring 25.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
