Description

Technical Field

[0001] This invention relates to the field of coating technology for conductive parts of power equipment, and particularly to a coating repair device and method. Background Technology

[0002] Copper, aluminum, and their alloys are commonly used as conductive materials in power systems. However, copper and aluminum exhibit extremely poor conductivity after oxidation, significantly reducing the conductivity of connection points. To prevent oxidation, the metal surface of conductive connections is often plated with silver or tin. After a period of operation, the plating at contact points is damaged due to friction, heat generation, oxidation, contamination, and corrosion, leading to increased contact resistance and overheating. Currently, the conventional troubleshooting method in China involves cleaning and polishing the joint surface, which inevitably causes further damage to the plating and does not fundamentally repair the damaged plating. Continued operation will cause the joint to overheat again, leading to frequent maintenance. While detachable components can be directly replaced, components directly connected to the primary equipment body present difficulties in replacement, resulting in long overall replacement cycles and high costs. Therefore, rapid on-site plating repair for these components is extremely important. On-site rapid plating repair technology is based on the working principle of electroplating, and temperature and humidity have a significant impact on the repair effect.

[0003] Existing coating repair equipment does not consider the impact of temperature and humidity on coating quality. As a result, poor coating quality and weak adhesion may occur due to excessively low or high temperature and humidity, failing to achieve the expected repair effect. Summary of the Invention

[0034] Example 1

[0035] Figure 1 This is a schematic diagram of a coating repair device provided in Embodiment 1 of the present invention. Figure 1 As shown, the device includes a repair host 1 and a repair handle 2.

[0036] The repair host 1 includes a main control board 101 and a temperature and humidity detection module 102. The temperature and humidity detection module 102 is used to detect the current ambient temperature and humidity. The main control board 3 generates a target repair voltage based on the current ambient temperature and humidity.

[0037] Specifically, the ideal temperature for brush plating is around 20℃, and the ideal relative humidity range is 30%–80%. To achieve the desired repair effect, the repair voltage must be adjusted according to the temperature and humidity. When the temperature is below 20℃, the repair voltage needs to be increased appropriately; when the temperature is above 20℃, the repair voltage needs to be decreased appropriately. When the humidity is below 30%, the repair voltage needs to be decreased appropriately; when the humidity is above 80%, the repair voltage needs to be increased moderately. By detecting the current ambient temperature and humidity, a target repair voltage is generated based on the current ambient temperature and humidity, thereby achieving the ideal repair effect.

[0038] The repair handle 2 is electrically connected to the main control board 101 and is used to repair the plating of the equipment to be repaired according to the target repair voltage.

[0039] Specifically, there can be multiple repair handles 2, including multi-functional repair handles. These multi-functional repair handles are used to match different repair process selections. Each repair handle can communicate with the host via RS485. Furthermore, the cable connecting the repair handle to the main control board includes a communication line. The repair process and output voltage can be modified through the repair handle to complete the plating repair function.

[0040] Figure 2 This is a schematic diagram of the specific circuit structure for implementing the coating repair device provided in Embodiment 1 of the present invention;

[0041] like Figure 2 As shown, the positive output 104 and negative output 105 of the repair host 1 are electrically connected to the repair handle 2, and the control circuit power supply 111 of the repair host 1 is electrically connected to the repair handle control board 201 in the repair handle 2.

[0042] Specifically, the repair host 1 also includes an alarm module 115, which is electrically connected to the main control board 101. The alarm module 115 provides a voice alarm when the repair time is up, the plating thickness is reached, or the current ambient temperature and humidity are unsuitable for repair. The alarm module 115 has a built-in voice alarm that reminds the operator to stop the plating repair when the repair time is up, the plating thickness is reached, or the ambient temperature and humidity are unsuitable for repair.

[0043] Furthermore, the repair unit 1 also includes an exhaust fan 110, which is electrically connected to the main control board 101 and is used to draw ambient air into the repair unit 1. Installing the exhaust fan 110 inside the repair unit 1 allows ambient air to be drawn into the repair unit 1.

[0044] Furthermore, the repair host 1 also includes a temperature and humidity detection module 102, which is electrically connected to the main control board 101 and is used to detect the current ambient temperature and humidity.

[0045] Optionally, the temperature and humidity detection module 102 is installed near the exhaust fan 110, which can monitor the ambient temperature and humidity in real time, and then transmit the monitored data to the main control board 101 via RS485. The main control board 101 adjusts the output voltage to the optimal repair voltage according to the sampled ambient temperature and humidity, so that the repair effect is optimal.

[0046] Furthermore, the repair host 1 also includes a power socket 108, a waterproof switch 109, a filter 114, a main power supply 113, and a control circuit power supply 111. The output terminal of the power socket 108 is electrically connected to the input terminal of the waterproof switch 109, the output terminal of the waterproof switch 109 is electrically connected to the input terminal of the filter 114, the first output terminal of the filter 114 is connected to the main power supply 113, and the second output terminal of the filter 114 is connected to the control circuit power supply 111.

[0047] When the circuit is working, the AC power is connected through the power socket 108 and then through the waterproof switch 109 to the filter 114. The output of the filter 114 is connected to the main power supply 113. The main power supply 113 converts the AC power into the DC power required for plating repair and connects it to the control circuit power supply 111 and the shunt 112 respectively.

[0048] Furthermore, the repair host 1 also includes a main control board 101. The first output terminal of the control circuit power supply 111 is electrically connected to the main control board 101 to supply power to the main control board 101. The second output terminal of the control circuit power supply 111 is electrically connected to the control output 107 to supply power to the repair handle control board 201 in the externally connected repair handle 2.

[0049] The repair handle control board 201 in the repair handle 2 is connected to supply power to the repair handle control board 201; wherein, the repair handle control board 201 is used to control the modification repair process and output voltage.

[0050] Furthermore, the repair host 1 also includes a shunt 112, a positive output terminal 104, and a negative output terminal 105. The main control board 101 also includes a main control board commutation circuit 1011. The output terminal of the main power supply 113 is electrically connected to the input terminal of the shunt 112. The first output terminal of the shunt 112 is electrically connected to the input terminal of the main control board commutation circuit 1011. The second output terminal of the shunt 112 is electrically connected to the main control board 101. The input terminal of the main control board commutation circuit 1011 is electrically connected to the positive output terminal 104 and the negative output terminal 105.

[0051] During circuit operation, the main power supply 113 converts AC to DC, which is then connected to the input terminal of the main control board commutation circuit 1011 after passing through the first output terminal of the shunt 112. The output from the main control board commutation circuit 1011 is then connected to the positive output terminal 104 and the negative output terminal 105, and finally connected to the repair handle 2 via a cable to provide power for repairing the plating. The second output terminal of the shunt 112 is electrically connected to the main control board 101, used to measure the voltage and current of the DC current passing through the shunt, and to feed back the DC voltage and current information to the main control board 101.

[0052] The shunt 112 is an instrument for measuring direct current. It is based on the principle that a voltage is generated across a resistor when direct current passes through it, and can measure the direct current passing through the shunt. The positive output 104 and the negative output 105 are used to output the repair voltage. The main control board commutation circuit 1011 can automatically switch the output positive and negative terminals according to the repair process requirements, avoiding manual replacement of the positive and negative cables and reducing the workload of operators.

[0053] Furthermore, the repair host 1 also includes a touch screen 103, which is electrically connected to the main control board 101 and is used to display the repair process in real time, as well as the output voltage, output current, repair time, ambient temperature and humidity and coating thickness information.

[0054] The touch screen 103 serves as a human-computer interaction tool, which can display the current repair process of the repair host 1 in real time, as well as information such as output voltage, output current, repair time, ambient temperature and humidity, and plating thickness. It can also set parameters such as working voltage, repair time, and power consumption coefficient, making it convenient for operators to control the repair host 1.

[0055] In addition, the repair handle 2 includes a repair handle control board 201, which is electrically connected to the control circuit power supply 111 and is powered by the control circuit power supply 111. The repair handle control board 201 is used to control the repair handle 2 to modify the repair process and output voltage.

[0056] In this embodiment, AC power is connected through power socket 108, then through waterproof switch 109 to AC filter 114. AC filter 114 connects to main power supply 113 on one side and control circuit power supply 111 on the other. Control circuit power supply 111 powers main control board 101 and repair handle control board 201. Main power supply 113 converts AC power into DC power required for plating repair. After passing through shunt 112, it connects to main control board commutation circuit 1011. The output from main control board commutation circuit 1011 connects to the positive and negative terminals 104 and 105 of the panel output, and then connects to repair handle 2 via cable, providing working power for plating repair. An exhaust fan 110 is installed inside the repair host 1 to draw ambient air into the host, serving two purposes: cooling main power supply 113 and enabling temperature and humidity detection module 102 to detect ambient temperature and humidity more quickly. The temperature and humidity detection module 102 is installed near the exhaust fan to monitor the ambient temperature and humidity in real time. The monitored data is transmitted to the main control board 101 via RS485. The main control board 101 adjusts the output voltage to the optimal level based on the sampled ambient temperature and humidity values ​​to achieve the best repair effect. The main control board's commutation circuit 1011 can automatically switch the positive and negative output terminals according to the repair process requirements, avoiding manual replacement of the positive and negative cables and reducing the workload of operators. The alarm module 115 provides a voice alarm function when the repair time is up, the plating thickness is reached, or the ambient temperature and humidity are unsuitable for repair.

[0057] This invention detects the current ambient temperature and humidity, adjusts the output voltage to the target repair voltage based on this temperature and humidity, and repairs the plating of the equipment to be repaired according to the target repair voltage. This solves the problem that existing plating repair equipment does not consider the impact of ambient temperature and humidity on plating quality, resulting in poor plating quality and weak adhesion due to excessively low or high temperatures and humidity, thus failing to achieve the expected repair effect. This invention better realizes on-site repair of the plating of primary connectors of power equipment, has an automatic temperature and humidity compensation function, and can automatically compensate the repair voltage according to the ambient temperature and humidity to achieve the best plating repair effect.

[0060] like Figure 3 As shown, the repair host 1 also includes a touch screen 103 disposed on the top of the outer casing. The touch screen 103 is connected to the main control board and is used to display information such as the repair process, output voltage, output current, repair time, ambient temperature and humidity, and plating thickness of the repair host.

[0067] Furthermore, the main control board 101, shunt 112, AC filter 114, and control loop power supply 111 of the above embodiment are disposed on the top surface of the internal heat dissipation channel of the repair host 1. The control loop power supply 111 is used to supply power to the main control board 101 and various electronic components connected to the main control board 101, and also to supply power to the repair handle control board 201.

[0073] The coating repair device provided in Embodiment 2 of this invention detects the current ambient temperature and humidity using a temperature and humidity detection module. The main control board generates a target repair voltage based on the current ambient temperature and humidity. This not only automatically compensates for the optimal repair voltage based on the ambient temperature and humidity, thus better repairing the coating of primary connectors of power equipment on-site, but also provides timely warnings when the ambient temperature and humidity exceed the range required for coating repair.

A built-in voice alarm provides voice alerts when the repair time is up, the coating thickness is reached, or the ambient temperature and humidity are unsuitable for repair.

[0074] Example 3

[0075] Figure 5This is a flowchart of a coating repair method provided in Embodiment 3 of the present invention. This method can be executed by a coating repair device from the above embodiments, such as... Figure 5 As shown, the method includes:

[0076] S110. Detect the current ambient temperature and humidity, and adjust the output voltage to the target repair voltage based on the current ambient temperature and humidity.

[0077] Specifically, the system samples the current ambient temperature and humidity in real time to determine whether the current ambient temperature and humidity are within the suitable temperature range for coating repair. If so, the output voltage is adjusted to the optimal target repair voltage based on the current ambient temperature and humidity. If not, a voice alarm is issued to indicate that the current ambient temperature and humidity are not suitable for coating repair.

[0078] In the process of plating repair, the ideal temperature is around 20℃, with a minimum of 10℃ and a maximum of 50℃. Currently, most conventional electroplating is performed indoors, where ambient temperature and humidity are relatively easy to control. However, when electroplating repair is moved outdoors, to a substation site, controlling the ambient temperature and humidity becomes very difficult, significantly impacting the repair outcome. In winter, when the ambient temperature is low, the initial temperature should not be lower than 10℃, and the workpiece must be preheated before plating. For workpieces that are difficult to preheat, only a higher voltage and lower movement speed can be used to initiate plating. If normal voltage is used to initiate plating at low temperatures, the plating layer will not crystallize easily, resulting in high stress and peeling. In summer, when the ambient temperature is higher than 20℃, a slightly lower voltage and faster movement speed can be used to initiate plating. If normal voltage is used, the plating layer will turn black, peel, and the bond between the plating layer and the substrate will be weak. The impact of ambient humidity on the repair effect must also be considered. When the ambient humidity is below 30%, the repair voltage should be appropriately reduced; when the humidity is above 80%, the repair voltage should be appropriately increased. Repair is not advisable when the ambient temperature and humidity exceed the required range.

[0079] S120. Repair the coating of the equipment to be repaired according to the target repair voltage.

[0080] Specifically, during the repair process of the coating on the equipment to be repaired, based on the target repair voltage, the target repair time and target coating thickness can be set. When the repair time and coating thickness are equal to the set target repair time and target coating thickness, the coating repair process is completed and a voice alarm is issued.

[0081] Existing coating repair methods do not consider the impact of temperature and humidity on coating quality. This can lead to poor coating quality and weak adhesion due to excessively low or high temperatures and humidity, failing to achieve the desired repair effect. The aforementioned coating repair method not only automatically compensates for the optimal repair voltage based on ambient temperature and humidity, enabling better on-site repair of primary joint coatings in power equipment, but also provides timely warnings when ambient temperature and humidity exceed the required range for coating repair.

[0082] The coating repair method provided in Embodiment 3 of this invention can monitor the ambient temperature and humidity in real time. When the ambient temperature and humidity are too high or too low, exceeding the requirements for coating repair, a voice warning will be issued. When the ambient temperature and humidity meet the requirements for coating repair, the repair voltage can be automatically compensated according to the ambient temperature and humidity to repair the coating of the equipment to be repaired, so that the coating repair effect reaches the best, the adhesion between the coating and the metal is stronger, and a voice alarm will be issued after the coating repair process is completed.

[0083] It should be understood that the various forms of processes shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this invention can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this invention can be achieved, and this is not limited herein.

[0084] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
