There are two fixed seats, which are respectively installed on both sides of the top surface of the workbench.

After electroplating, the through holes formed by the unilateral semi-circular plate one and semi-circular plate two can be blocked to prevent harmful gases from escaping outside the electroplating tank.

Description

Technical Field

[0001] The present invention relates to the technical field of electroplating equipment, and particularly to a long optical rod electroplating tooling. Background Art

[0002] Long optical rods, such as hydraulic piston rods, etc., are widely used in various mechanical equipment. In order to improve their service life and performance, electroplating treatment, such as chrome plating, nickel plating, zinc plating, copper plating, etc., is usually required on their surfaces. However, there are many deficiencies in the existing electroplating technology when applied to long optical rods.

[0003] In the existing electroplating process, the electroplating solution often contains various substances harmful to the human body. When the electroplating solution is electrified, these harmful substances will volatilize into the air at a relatively fast speed, polluting the operating environment.

[0004] In addition, for the electroplating treatment of long optical rods, the existing technology generally adopts the hanging plating method. Specifically, the long optical rod is hung on the fixture, then the negative electrode of the power supply is connected to the long optical rod, and the long optical rod is immersed in the electroplating solution through the fixture, and the power supply is turned on for electroplating. However, due to the long length of the long optical rod, the electroplating tank often needs to be set deeper, which not only increases the danger of electroplating operations, but also makes it laborious and inconvenient to transfer the long optical rod above the electroplating tank.

[0005] More critically, during the hanging plating process, it is often difficult to form a uniform coating on the parts where the fixture, the negative electrode wire and the long optical rod are in contact, and even in some cases, no coating can be formed. This not only affects the electroplating quality of the long optical rod, but also limits the use effect of the electroplating tooling.

[0006] In summary, the existing electroplating technology has problems such as environmental pollution, high operation danger, inconvenient transfer, and uneven coating when applied to long optical rods, and it urgently needs to be improved. For this reason, we propose a long optical rod electroplating tooling. Summary of the Invention

[0007] To solve the above technical problems, the present invention provides a long optical rod electroplating tooling, including a workbench, on which a fixed seat is installed.

[0014] A filtering mechanism is installed on the workbench at one end of the support tube away from the conductive ring, and the filtering mechanism filters the harmful gases generated during the electroplating process.

[0016] In some embodiments, the conduction mechanism includes a fixing ring installed at one end of the support tube close to the servo motor. The fixing ring is provided with sliding grooves, the number of the sliding grooves is the same as the number of the conductive rods and they are distributed in one-to-one correspondence. Telescopic rods I are installed in the sliding grooves. One end of the telescopic rod I is connected to the conductive ring, and the other end is installed with a conductive column. A tension spring is arranged in the telescopic rod I. The conduction mechanism further includes a limiting member installed on the conductive column, and the limiting member drives the conductive rod to be in contact with the corresponding conductive rod only when it moves to the lower position in the electroplating tank.

The filtering mechanism further includes a switching member installed on the corresponding semi-circular plate one and semi-circular plate two on one side. When the switching member fits at both ends of the support cylinder and the semi-cylindrical tube, it drives the sealing cover to communicate with the electroplating tank through the semi-circular cover. When the semi-cylindrical tube rotates away from the support cylinder, the contact between the sealing cover and the semi-cylindrical tube is disconnected.

Detailed Description of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1:

[0038] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a long optical rod electroplating tooling, including a workbench 1, on which a fixing seat 11 is installed. There are two fixing seats 11, which are respectively installed on both sides of the top surface of the workbench 1. A bearing 12 is rotatably connected to each fixing seat 11, and an electroplating tank 13 is installed through the bearing 12. The electroplating tank 13 stores electroplating solution. The electroplating tank 13 is composed of a support cylinder 131 and a semi-cylindrical cylinder 132 rotatably connected to the support cylinder 131. The two ends of the support cylinder 131 are annular, and the middle is semi-circular connecting the two ends. A male snap 14 is installed on the support cylinder 131, and a female snap 15 is installed on the semi-cylindrical cylinder 132. It further includes:

[0039] Two semi-circular plates 2, which are respectively installed on both sides of the middle semi-circular part of the support cylinder 131;

[0040] Two semi-circular plates 3, the number of which is the same as that of the semi-circular plates 2, are installed in the semi-cylindrical cylinder 132 and are arranged corresponding to the semi-circular plates 2;

[0041] A plurality of conductive rods 4 are arranged in a circular array in the support cylinder 131 and the semi-cylindrical cylinder 132, and both ends penetrate through the semi-circular plates 2 and 3 respectively. The conductive rods 4 are made of inert conductive materials or metal materials plated with an inert conductive coating;

[0042] A conductive ring 5 is installed at one end of the support cylinder 131, is fixed to the inner wall of the annular part of the support cylinder 131, and is connected to the negative electrode of the power supply required in the electroplating process;

[0043] In the long-term statistical process, for the coatings of long optical rods, the vast majority are chromium coatings, and a small part uses nickel coatings or zinc coatings. For the processing of such coatings, an aluminum alloy rod with a silver coating of not less than 0.2 mm on the surface can be used as the electroplating rod, which has a low use cost and will not react with the electroplating solution.

[0044] A rotating mechanism 6 is installed on the workbench 1 and is connected to the support cylinder 131. The rotating mechanism 6 drives the electroplating tank 13 to rotate and drives the electroplated parts to rotate in the electroplating tank 13;

[0045] The conduction mechanism 7 is installed on the support cylinder 131, connected to the conductive ring 5, and in contact with the corresponding end of the conductive rod 4. The conduction mechanism 7 transmits the negative current on the conductive ring 5 to the conductive rod 4 near the workpiece to be plated. Through the contact between the workpiece to be plated and the conductive rod 4, the workpiece to be plated is in the cathode state;

[0046] The filtering mechanism 8 is installed on the workbench 1, at the end of the support cylinder 131 away from the conductive ring 5. The filtering mechanism 8 filters the harmful gases generated during the electroplating process.

[0047] The rotating mechanism 6 includes a servo motor 61 installed on the workbench 1. A first gear 62 is sleeved on the driving shaft of the servo motor 61. An external gear ring 63 is sleeved on one end of the support cylinder 131 close to the servo motor 61. The first gear 62 meshes with the external gear ring 63.

[0048] For some long and light optical rods, the staff can directly insert them into the electroplating tank 13 through the through hole formed between the semi-circular plate one 2 and the semi-circular plate two 3 near the servo motor 61. For long and heavy optical rods, the staff rotates the flat part of the semi-circular plate one 2 to a horizontal plane parallel to the ground through the servo motor 61, disconnects the connection between the male buckle 14 and the female buckle 15, and rotates the semi-cylindrical barrel 132. Then, the long optical rod can be put into the support cylinder 131 through a lifting tool, and then reset in sequence. It should be noted that during the electroplating process, the servo motor 61 operates at a low power, and the diameter of the first gear 62 on the driving shaft of the servo motor 61 is much smaller than that of the external gear ring 63. The rotation rate of the electroplating tank 13 driven by the external gear ring 63 is further reduced. The electroplating tank 13 rotates slowly. On the one hand, it can avoid the detachment of the just-formed coating on the long optical rod due to contact with the conductive rod 4. At the same time, under the action of the self-gravity of the long optical rod, it always remains at the bottommost position of the inner wall of the electroplating tank 13 and rotates slowly synchronously with the rotation of the electroplating tank 13, so as to electroplate the surface of the long optical rod without dead angles and avoid the electroplating solution splashing to the outside due to too fast rotation.

[0049] The conduction mechanism 7 includes a fixed ring 71 installed at one end of the support cylinder 131 close to the servo motor 61. A chute 72 is opened on the fixed ring 71. The number of chutes 72 is the same as the number of conductive rods 4 and they are distributed in one-to-one correspondence. One end of a telescopic rod one 73 is connected to the conductive ring 5, and the other end is installed with a conductive column 74. A tension spring 75 is arranged in the telescopic rod one 73. The conduction mechanism 7 further includes a limiting member 76 installed on the conductive column 74. The limiting member 76 drives the conductive rod 4 to contact the corresponding conductive rod 4 only when it moves to the lower position inside the electroplating tank 13.

[0050] The limiting member 76 includes a fixing block 761 mounted on the conductive column 74. The fixing block 761 is provided with a guiding groove 762. A supporting block 763 is mounted on the workbench 1, and support rods 764 are oppositely mounted on the supporting block 763. One ends of the two support rods 764 away from the supporting block 763 are connected by a guiding plate 765. The guiding plate 765 is arc-shaped when viewed from the front and top. Specifically, the guiding plate 765 is an arc coaxial with the supporting cylinder 131, and the middle part protrudes towards the central position of the supporting cylinder 131.

[0051] During the rotation of the electroplating tank 13 driven by the rotating mechanism 6, since the first telescopic rod 73 is in contact with the conductive ring 5, the conductive ring 5 transmits the negative current to the conductive column 74 through the first telescopic rod 73. Under the action of the tension spring 75, the conductive column 74 receives a force away from the conductive rod 4. As the electroplating tank 13 rotates, the fixing block 761 is driven to rotate synchronously through the sliding groove 72, the first telescopic rod 73, and the conductive column 74. Under the extrusion of the guiding plate 765, the guiding groove 762 on the fixing block 761 approaches the long optical rod while gradually driving the conductive column 74 closer to the conductive rod 4 until it finally fits with the conductive rod 4, transmitting the negative current to the long optical rod through the conductive rod 4, thereby driving the long optical rod to be in a negative state for electroplating. The design of only the conductive rod 4 near the long optical rod transmitting the negative current enables efficient utilization of the current. At the same time, the conductive rod 4 will have more time without carrying the negative current, avoiding the situation of unstable plating or substrate due to long-term contact with the negative current and the electroplating solution.

[0052] The filtering mechanism 8 includes a semi-circular cover 81 mounted on the semi-circular plate one 2 and the semi-circular plate two 3 away from the conductive ring 5. The inner diameter of the semi-circular cover 81 is equal to the inner diameter of the semi-circular plate one 2, and rubber sheets 82 are provided on the inner walls. A filter box 83 is mounted on the rubber sheet 82 on the supporting cylinder 131. The filter box 83 is detachable. A negative pressure machine 84 is mounted on the workbench 1. A hose 85 is connected to the negative pressure machine 84. One end of the hose 85 away from the negative pressure machine 84 is sleeved with a metal ring 86. A sealing cover 87 is rotatably connected to the metal ring 86. The inner diameter of the sealing cover 87 is equal to the inner diameter of the semi-circular cylinder 132, and the side opposite to the semi-circular cylinder 132 is made of rubber. The filtering mechanism 8 further includes a switching member 88 mounted on the corresponding semi-circular plate one 2 and semi-circular plate two 3. When the supporting cylinder 131 and the semi-circular cylinder 132 are in contact at both ends, the switching member 88 drives the sealing cover 87 to communicate with the electroplating tank 13 through the semi-circular cover 81. When the semi-circular cylinder 132 rotates away from the supporting cylinder 131, the contact between the sealing cover 87 and the semi-circular cylinder 132 is disconnected.

[0053] The switching member 88 includes a telescopic rod two 881 relatively installed on the semi-circular plate one 2 near one side of the negative pressure machine 84. Compression springs 882 are arranged inside the telescopic rods two 881. L-shaped rods 883 are fixed to the ends of the telescopic rods two 881 far from the semi-circular plate one 2. The L-shaped rods 883 are respectively fixed to both ends of the sealing cover 87. Extrusion grooves 884 are mirror-image formed on the L-shaped rods 883. The upper part of the extrusion groove 884 is trapezoidal and the lower part is square. A trigger rod 885 is relatively installed on the corresponding semi-circular plate two 3 on one side. The trigger rod 885 is L-shaped and one end is beveled.

[0054] During the electroplating process of the long optical rod, the negative pressure machine 84 is turned on. The electroplating tank 13 is always in a negative pressure state, and the air flows in the direction of the negative pressure machine 84. The through-hole formed between the semi-circular plate one 2 and the semi-circular plate two 3 near one end of the servo motor 61 becomes the air inlet to supplement the gas in the electroplating tank 13. Due to the electrolytic reaction in the electroplating tank 13, the harmful gases generated by the electroplating solution pass through the filter box 83 during the process of flowing towards the negative pressure machine 84. The filter box 83 filters the harmful substances therein to prevent the harmful substances from entering the outside.

[0055] After the electroplating of the long optical rod is completed, the power supply in the electroplating system is turned off. At this time, the evaporation rate of the electroplating solution without current drops significantly. The negative pressure machine 84 continues to operate for a period of time to ensure that the concentration of harmful gases in the electroplating tank 13 is reduced to a safe range. Subsequently, the negative pressure machine 84 stops working. The servo motor 61 rotates the flat part of the semi-circular plate one 2 to be in the same horizontal plane as the ground, releases the connection between the male buckle 14 and the female buckle 15, and opens the semi-cylindrical barrel 132, then the electroplated long optical rod can be taken out.

[0056] During the process of opening the semi-cylindrical barrel 132, the trigger rod 885 connected to the semi-circular plate two 3 on the semi-cylindrical barrel 132 disengages from the extrusion groove 884 of the L-shaped rod 883. Under the action of the compression spring 882, the telescopic rod two 881 elongates, drives the sealing cover 87 away from the semi-circular cover 81 through the L-shaped rod 883, making the subsequent opening more labor-saving, and at the same time increasing the operable space when replacing the filter box 83. On the contrary, during the process of closing the semi-cylindrical barrel 132, the trigger rod 885 squeezes the extrusion groove 884 on the L-shaped rod 883, and finally drives the sealing cover 87 to fit with the combined semi-cylindrical barrel 132 to complete the sealing of the part fitting with the semi-circular cover 81.

[0057] Embodiment 2:

[0058] Refer to Figure 1 、 Figure 9 On the basis of Embodiment 1 of the present invention, the present solution is further optimized:

[0059] A discharge groove 16 is formed on the top surface of the workbench 1.

[0060] When the electroplating solution in the electroplating tank 13 needs to be replaced or discharged, a device for recycling waste liquid is placed at the bottom of the discharge tank 16, and the servo motor 61 rotates the flat part of the semi-circular plate 1 to the same horizontal plane as the ground, disconnecting the connection between the male buckle 14 and the female buckle 15. The servo motor 61 drives the electroplating tank 13 to gradually tilt, so that the electroplating solution flows into the device for recycling waste liquid.

[0061] A sealing cover 9 is provided for the through hole formed by the cooperation of the semi-circular plate 1 and the semi-circular plate 2 on the side close to the servo motor 61.

[0062] When the equipment is not in use, if the electroplating solution in the electroplating tank 13 is to volatilize to the outside, it can only pass through the through hole formed between the two semi-circular plates 1 and the semi-circular plate 2. A filter box 83 is provided on the side close to the negative pressure machine 84, and the other side can be sealed by the sealing cover 9 to prevent harmful substances from entering the outside air.

[0063] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.
