Description

Technical Field

[0001] The invention relates to the technical field of metal electroplating, and in particular to a metal part surface electroplating treatment device based on CNC machine tool processing. Background Art

[0002] CNC machine tool processing occupies an extremely important position in modern manufacturing. With its significant advantages of high precision, high automation and strong repeatability, it can accurately process metal materials into various complex and precise shapes and sizes. However, simply meeting the shape and size accuracy requirements of parts is far from meeting the stringent standards of practical applications. For metal parts processed by CNC machine tools, their surface treatment is also a key link that affects the performance and service life of parts.

[0003] Among many surface treatment technologies, electroplating is a very common and effective method. Electroplating of metal parts is to immerse the parts in a plating solution containing specific metal ions, and deposit a uniform and dense metal or alloy coating on the surface of the parts by electrolysis. This coating can not only significantly improve the surface hardness, wear resistance and corrosion resistance of the parts, effectively extend the service life of the parts, but also greatly improve the important properties of the parts such as electrical conductivity, thermal conductivity and lubricity, thereby meeting the diverse needs of parts in different fields.

[0004] However, under existing technical conditions, there are many problems that need to be solved when electroplating metal parts processed by CNC machine tools. On the one hand, since parts processed by CNC machine tools often have more complex and sophisticated structures, traditional electroplating processes face huge challenges in controlling current density and current distribution. When the current density is too low, it is very easy to cause problems such as uneven electroplating layer and slow electroplating speed. In severe cases, it may even produce "roller eye marks" that are difficult to eliminate on the surface of the parts, resulting in the inability to form a complete and qualified coating. On the other hand, for parts with complex shapes processed by CNC machine tools, the unevenness of the surface current distribution is more prominent. Conventional electroplating methods are difficult to ensure that all parts of the parts can obtain appropriate current density, which affects the consistency and stability of the electroplating effect. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art, such as: in the prior art, the current density and current distribution cannot be controlled.

A temperature sensor is embedded in the front of the side cabinet 101, and the temperature sensor is electrically connected to the controller 103 through a wire. The temperature sensor monitors the temperature of the electroplating solution inside the electroplating box 2 in real time, and transmits the monitoring electrical signal to the controller 103 through the wire for calculation. When the controller 103 calculates that the temperature of the electroplating solution inside the electroplating box 2 reaches the set value, the controller 103 controls the high-frequency power supply 5 to stop running, ensuring that the temperature of the electroplating solution inside the electroplating box 2 is within the set range.

[0038] Furthermore, a box cover 201 is installed on the top of the electroplating box 2 through a slide groove, a servo motor 202 is fixedly installed on one side of the electroplating box 2, and the output end of the servo motor 202 is fixedly connected to the box cover 201 through a shaft;

[0039] It should be noted that the interior of the electroplating box 2 is composed of an upper electroplating pool and a lower installation room. When the servo motor 202 is powered on, it drives the box cover 201 to flip over. The flipped box cover 201 is folded and displaced using a slide groove to achieve the purpose of automatically opening the box cover 201. The box cover 201 can also be used to protect the plating liquid inside the electroplating box 2 to prevent the plating liquid from spilling during the stirring process, thereby avoiding loss of the plating liquid.

The high-frequency power supply machine 5 provides power to the heater 501 through the cable 503, so that the heater 501 can convert electrical energy into thermal energy to heat the plating liquid in the upper electroplating pool inside the electroplating box 2.

[0046] Further, the inner wall of the side cabinet 101 is fixedly installed with a driving mechanism 6 extending into the inside of the electroplating box 2, and the driving mechanism 6 includes a servo motor A601, a protective sleeve B602, a right-angle commutator 603, and a transmission rod 604.

The rotating screw rod 702 cooperates with the mounting frame through the thread sleeve 703 to drive the slide rail member 205 to move vertically. The upward moving slide rail member 205 drives the turntable 801 to lift upward through the planetary gear 803 and the bracket 802. The lifted turntable 801 makes the connecting pin hole 805 away from the transmission pin rod 605, so that the turntable 801 can be disassembled, which is convenient for disassembly and cleaning of the rotating planetary mechanism 8.

[0052] Working principle: Before using the device, the user first tests the device and uses it after confirming that there is no problem. The controller 103 controls the servo motor 202 to power on through the wire, and the servo motor 202 drives the box cover 201 to flip. The flipped box cover 201 uses the slide groove to fold and move, so as to achieve the purpose of automatically opening the box cover 201.

[0053] The controller 103 controls the servo motor 202 to be powered on and run through the wire, and the servo motor B704 drives the screw rod 702 to rotate forwardly. The screw rod 702 that rotates forwardly cooperates with the mounting frame through the thread sleeve 703 to drive the slide rail member 205 to move vertically upward. The upwardly moving slide rail member 205 drives the roller 3 to be lifted upward through the planetary gear 803 and the plug pin 804 to lift the electroplating liquid level inside the upper electroplating pool, and then the roller 3 installed by plugging the plug pin 804 and the plug slot 301 is disassembled, and small-sized parts are placed inside the roller 3, and then the plug pin 804 and the plug slot 301 are used to plug and install the roller 3, and the servo motor B704 drives the screw rod 702 to rotate in the opposite direction. The screw rod 702 that rotates in the opposite direction cooperates with the mounting frame through the thread sleeve 703 to drive the slide rail member 205 to move vertically downward, so that the roller 3 is immersed in the electroplating liquid level inside the upper electroplating pool;

[0054] The controller 103 controls the high-frequency power supply 5 to start up through the wire, and the high-frequency power supply 5 provides power to the heater 501 through the cable 503, so that the heater 501 converts electrical energy into thermal energy to heat the electroplating solution inside the electroplating box 2. At the same time, the temperature of the electroplating solution inside the electroplating box 2 is monitored in real time through the temperature sensor, and the monitoring electrical signal is transmitted to the controller 103 through the wire for calculation. When the controller 103 calculates that the temperature of the electroplating solution inside the electroplating box 2 reaches the set value, the controller 103 controls the high-frequency power supply 5 to stop running, thereby ensuring that the temperature of the electroplating solution inside the electroplating box 2 is within the set range;

[0055] The servo motor A601 is powered on to drive the transmission rod 604 to rotate, and the rotating transmission rod 604 drives the transmission pin 605 to rotate through the right-angle commutator 603. The rotating transmission pin 605 drives the turntable 801 to rotate through the connecting pin hole 805 connected by the plug pin. The rotating turntable 801 drives the bracket 802 to rotate. The rotating bracket 802 drives the planetary wheel 803 to perform planetary rolling rotation on the circular track inside the slide rail 205, and the planetary rolling rotating planetary wheel 803 drives the roller 3 to move through the plug pin 804. The planet rolls and rotates. The roller 3 of the planet rolls and rotates fully to turn over the metal parts inside, avoiding the "roller eye mark" at the holes of the roller 3. At the same time, the rotating and rolling metal parts can make the cathode or anode move relative to the parts during the electroplating process. The moving cathode method is used to improve the uniformity of current distribution, thereby ensuring that each part of the part can obtain the appropriate current density. At the same time, the electroplating solution is also stirred during the rotation of the bracket 802. Stirring can keep the ion concentration in the electrolyte evenly distributed to avoid excessively high or low local concentrations.

[0056] For large-sized parts, the use of the bracket 802 can be adjusted to perform hanging electroplating. The roller 3, the planetary gear 803 and the plug pin 804 are removed, and the shaft is unlocked by rotating the screw bolt. The shaft is turned inward with the screw bolt as the axis, so that the shaft is away from the slide rail 205 to form a certain tilt angle. The metal parts are hung through the hanging hole at the top of the shaft, and the electroplating treatment method of the metal parts is changed, so that the parts of different specifications can be electroplated.

[0057] The anode piece 203 is activated by a power supply, and the metal part is immersed in the electroplating solution containing the required metal ions. The cathode piece 204 is connected to the metal part, and a metal or alloy layer is deposited on the metal surface by electrolysis.

[0058] During the electroplating process, the controller 103 controls the circulation pump 404 to be powered on and run. The circulation pump 404 starts to generate suction and is transported to the liquid inlet pipe 405 through the pipeline. The suction inside the liquid inlet pipe 405 is used to draw the plating liquid in the upper plating pool inside the plating box 2 into the filter element 402. Under the action of high pressure, impurities inside the plating liquid are filtered, and the filtered plating liquid leaks to the bottom of the filter tank 401. The control valve pipe 407 is opened by the controller 103. Under the action of high pressure, the filtered plating liquid is transported to the liquid outlet pipe 406 through the branch pipe to replenish the plating liquid inside the plating box 2, thereby achieving the purpose of circulating and filtering the plating liquid inside the plating box 2. The filtration can remove impurities and suspended matter in the electrolyte to ensure the purity of the plating liquid.

[0059] At the same time, the plating liquid transported by the liquid outlet pipe 406 will produce an aeration disturbance, which can fully and evenly mix the plating liquid inside the plating box 2. The pressure gauge 408 can monitor the internal air pressure of the filter tank 401 in real time, and transmit the monitoring electrical signal to the controller 103 through a wire for calculation. When the controller 103 calculates that the internal air pressure of the filter tank 401 reaches the set value, the controller 103 controls the circulation pump 404 to close and the control valve pipe 407 to open through the wire, thereby achieving the purpose of automatic pressure relief.

[0060] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
