Description

Technical Field

[0001] The present invention relates to the technical field of power supply equipment, and in particular to a rectifier and an electroplating system having the rectifier. Background Art

[0002] Rectifier is also widely known as electroplating power supply, electrolytic power supply or electrophoresis power supply. It is a power supply device, which is widely used in the electroplating process of hardware and the electroplating process of ABS. Rectifier can be used to adjust current and voltage, that is, it can adjust the current and voltage of the input AC power to meet the needs of different processes; rectifier can also be used for AC-DC conversion, that is, through the rectifier circuit, AC power is converted into DC power. This process is very important in many fields, such as the speed regulation of DC motors and the excitation regulation of generators. Rectifier plays a key role in industrial processes such as electroplating, aluminum oxidation, and electrolysis, providing the necessary power for these processes. Rectifiers usually include components such as main circuits, filters, synchronization modules, and transformers to ensure that AC power is effectively converted into DC power, and the output DC power is stable and suitable for subsequent use needs. In general, rectifier is an important power supply device. It provides necessary power support for various industrial applications that require DC power by adjusting and converting current.

[0003] The existing rectifier has a transformer assembly and a synchronization module assembly electrically connected to the transformer assembly. The transformer assembly can achieve voltage matching and electrical isolation, that is, the transformer assembly can convert the input AC voltage to a level suitable for the operation of the rectifier circuit, and achieve electrical isolation between the AC power grid and the rectifier circuit to ensure a safe and stable working state; in addition, the output voltage can also be adjusted through the transformer assembly, that is, the main function of the rectifier circuit is to convert AC power into unidirectional pulsating DC power, and the transformer assembly can adjust the output DC voltage to meet the needs of different devices; in general, the transformer assembly in the rectifier not only ensures voltage matching and electrical isolation, but also adjusts the voltage during the rectification process to adapt to different application scenarios; however, the transformer assembly and the synchronization module assembly in the existing rectifier are rigidly connected through a conductive copper plate or a conductive aluminum rod. During transportation, due to shaking, the rectifier and its internal components shake together, thereby causing the conductive copper plate or the conductive aluminum rod in the rectifier to directly or indirectly pull the circuit board connected thereto, thereby causing the power tube on the circuit board to be pulled, causing the power tube to be damaged, affecting the normal operation of the rectifier. The synchronous module components in the rectifier can improve energy conversion efficiency and reduce energy loss, so that the rectifier can operate with higher efficiency and lower energy consumption while providing stable DC output; currently, in the rectifier, the synchronous module components are directly connected to the heat dissipation components through a conductive base plate, which causes the heat dissipation components to be charged. When the heat dissipation components are water-cooled, the minerals in the water are easily adsorbed on the pipe wall or the pipe mouth. As more and more minerals are adsorbed, they will occupy the space inside the pipe, resulting in poor water flow and affecting the heat dissipation effect. Summary of the invention

[0004] The present invention aims to solve the technical problems existing in the above-mentioned prior art and provide a rectifier, which can not only prevent the power tube on the circuit board from being damaged by pulling, but also facilitate the effective heat dissipation of the rectifier.

DETAILED DESCRIPTION

[0032] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the relevant drawings.

[0033] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to another element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] In this embodiment, a specific implementation method of a rectifier is provided, wherein the rectifier in this embodiment can be a rectifier with a single output structure in the prior art, or a rectifier with a dual output structure to be protected in the present invention. The so-called single-output rectifier means that only one load can be connected, while the dual-output rectifier can be connected to two loads at the same time and work independently of each other. In this embodiment, the dual-output rectifier is used as an example to describe the synchronous module installation structure.

[0036] See also Figure 1 and 2 , including a rectifier installation housing 1, a heat dissipation component is arranged in the rectifier installation housing 1, a synchronization module component is connected to the heat dissipation component, and a transformer component is electrically connected to the synchronization module component; see Figure 3-4The synchronous module assembly includes a PCB board 2, which is an intelligent drive and protection circuit board. The circuit structure on the PCB board 2 and the functions it realizes are all prior arts, and the functions and circuit structure of the PCB board 2 itself are not the inventive points of the present invention; the synchronous module assembly also includes a conductive base plate 3 and a conductive strip 4, the PCB board 2 connects the conductive base plate 3 and the conductive strip 4, and the connection method is mainly that the PCB board 2 is detachably connected to the conductive base plate 3 and the conductive strip 4 at the same time through fasteners; the synchronous module assembly is connected to the heat dissipation assembly through the conductive base plate 3 and the conductive strip 4, and an insulating layer 5 is provided between the conductive base plate 3 and the heat dissipation assembly and between the conductive strip 4 and the heat dissipation assembly to isolate the conductive; the synchronous module assembly is formed into a whole by the action of the conductive base plate 3 and the conductive strip 4, so as to facilitate the installation of the synchronous module assembly in the rectifier, and then the conductive strip 4 and the conductive base plate 3 of the synchronous module assembly are connected to the conductive base plate 3 and the conductive strip 4. An insulating layer 5 for isolating conduction is provided between the heat dissipation components, which can prevent the current on the synchronous module component from being guided to the heat dissipation component. When the heat dissipation component adopts water cooling for heat dissipation, it can effectively prevent the minerals in the water from being adsorbed on the pipe wall or the pipe mouth, and prevent the minerals from occupying the internal space of the pipe, thereby ensuring smooth water flow, thereby ensuring effective heat dissipation of the heat dissipation component. In addition, the effective heat dissipation of the rectifier can reduce the loss of energy consumption; specifically, there are two conductive strips 4, which are respectively arranged on both sides of the conductive bottom plate 3, and each conductive strip 4 corresponds to a PCB board 2; the insulating layer 5 can be a whole piece, and a whole piece of insulating layer 5 covers the surface of two conductive strips 4 and the conductive bottom plate 3 at the same time, or the number of insulating layers 5 is consistent with the number of conductive strips 4 and the conductive bottom plate 3. For example, when the total number of the conductive bottom plate 3 and the conductive strips 4 is three, the number of insulating layers 5 is also three, and an insulating layer 5 is respectively arranged on the surface of each conductive strip 4 and the surface of the conductive bottom plate 3.

[0037] In this embodiment, see Figure 2 as well as Figure 5-6 The transformer assembly includes a magnetic core skeleton, one end of which is connected to the conductive bottom plate 3 of the synchronous module assembly, a magnetic core 6 is arranged on the magnetic core skeleton, and an output copper plate is also connected to the other end of the magnetic core skeleton, and a flexible conductive member 7 is connected to the output copper plate, and the flexible conductive member 7 is also connected to the conductive strip 4 of the synchronous module assembly. The flexible conductive member 7 is a soft copper strip, and the soft copper strip includes a first connecting end arranged horizontally and a second connecting end arranged horizontally, and the first connecting end and the second connecting end are connected through an intermediate connecting portion, and the intermediate connecting portion of the soft copper strip passes through a through hole 8 in the middle of the magnetic core skeleton and an inner hole of the magnetic core 6, and the first connecting end of the soft copper strip is connected to the output copper plate, and the second connecting end is connected to the conductive strip 4 of the synchronous module assembly; the intermediate connecting portion can be in a Z shape, such as Figure 5 and Figure 6As shown, it is convenient to pass through the through hole 8 in the middle of the magnetic core skeleton and the inner hole of the magnetic core 6 to avoid interference, and at the same time, the transformer as a whole is more beautiful; of course, the intermediate connecting portion can also be an arc, as long as the arc-shaped intermediate connecting portion can pass through the through hole 8 in the middle of the magnetic core skeleton and the inner hole of the magnetic core 6 without interfering with them. The intermediate connecting portion can also be formed by setting the first section and the second section in an angled state, such as Figure 3 As shown. The soft copper tape has good flexible connection performance and heat dissipation performance, that is: the soft copper tape is made of copper, which is a metal with good flexibility and can be bent multiple times without breaking, which enables the soft copper tape to adapt to various installation conditions and movement states. Copper is also a metal with excellent thermal conductivity and can quickly transfer heat; in addition, the soft copper tape is flat in shape, which increases the area in contact with the air, which is not only conducive to heat dissipation, but also easier to bend into the required shape, and can easily cope with the needs of complex wire connections and circuit designs; therefore, the transformer assembly is flexibly electrically connected to the synchronization module through the soft copper tape, which not only avoids direct or indirect damage to the power tube on the circuit board due to pulling at the connection, but also improves the heat dissipation performance and avoids damage to the power tube due to overheating.

[0038] In this embodiment, the insulating layer 5 is made of ceramic. When ceramic is used as the insulating layer 5, it has high mechanical strength and high thermal conductivity, which means that it can effectively conduct heat, which is beneficial to the heat dissipation of the synchronization module assembly and the transformer assembly; the conductive bar 4 is made of copper; the conductive base plate 3 is made of aluminum.

It can be understood that the angle between the first connecting plate 26 and the second connecting plate 27 can be 90°, the connection between the first connecting plate 26 and the second connecting plate 27 is rounded, and the second connecting plate 27 and The angle of the third connecting plate 28 can also be 90°, and the connection between the second connecting plate 27 and the third connecting plate 28 is rounded. Through the above structure, the output copper plate can be connected to the first output copper bus 10 and can be bent toward the synchronization module assembly, so that the overall module structure formed by the synchronization module assembly and the transformer assembly is compact; one end of the flexible conductive member 7 is connected to the first connecting plate 26, the third connecting plate 28 is connected to the first output copper bus 10, and the second output copper bus 10 and the first output copper bus 12 are respectively electrically connected to the positive and negative poles of the load, thereby realizing power supply to the load.

[0044] In this embodiment, see Figure 2, a current sensor 29 and a reactor 30 are provided on the second output copper bar 10. Among them, the reactor 30 can limit the sudden change of current when used in the rectifier, thereby reducing the current fluctuation and voltage spike, which helps to stabilize the DC output, especially when the power supply or load changes, it can maintain the continuity and stability of the current, while the current sensor 29 can monitor and adjust the current passing through the rectifier, provide real-time current readings, and ensure that the current remains within a safe and predetermined operating range. In addition, the current sensor 29 can also detect abnormal conditions such as short circuits or overloads, thereby triggering protective measures to prevent equipment damage; through the combined use of the current sensor 29 and the reactor 30, not only can the overall performance and reliability of the system be improved, but also the equipment can be protected from potential electrical hazards.

[0045] In a preferred embodiment, see Figure 1-7 The heat dissipation assembly includes a heat dissipation baffle 31, and the synchronous module assembly is connected to the heat dissipation baffle 31 through an insulating layer 5. Since the rectifier of the dual output structure is adopted in this embodiment, there are two sets of synchronous module assemblies, and the two sets of synchronous module assemblies are arranged on the two side walls of the heat dissipation baffle 31; a U-shaped water channel is arranged inside the heat dissipation baffle 31, and the two ends of the U-shaped water channel are penetrated by the wall surface of the heat dissipation baffle 31, one port of the U-shaped water channel is a water inlet, and the other port is a water outlet, and a water pipe joint 32 is arranged on the water inlet and the water outlet respectively, and a water pipe sleeve 33 is arranged on the water pipe joint 32, and water circulation is realized through the U-shaped water channel, which is convenient for dissipating heat inside the rectifier and taking away heat in time. In addition, a heat dissipation hole 37 is also arranged on the rectifier mounting shell 1, so that the external air can be connected with the inside of the rectifier to further dissipate the heat inside the rectifier.

[0046] This embodiment also specifically provides an implementation method of an electroplating system, see Figure 1-8, including at least two of the above-mentioned rectifiers, that is, the number of rectifiers is determined according to the number of electroplating tanks 34, the electroplating efficiency or the length of the workpiece to be electroplated. This embodiment provides a specific implementation of an electroplating tank 34 and two rectifiers. The electroplating tank 34 is square, and the two rectifiers are arranged on one side of the wide side of the electroplating tank 34, which can greatly shorten the wiring distance between the rectifier and the workpiece to be electroplated in the electroplating tank 34 and the metal 35, that is, the length of the wire can be reduced to reduce the resistance, thereby reducing the voltage drop and energy loss during the transmission process, ensuring that the current and voltage reaching the electroplating tank 34 are more stable, thereby improving the electroplating quality, that is, stable current and voltage are very important for ensuring the quality of the electroplating layer. The quality of the electroplating layer is very important, including its uniformity, adhesion and corrosion resistance. Due to the stability of current and voltage, the quality of the electroplating layer is high, thus avoiding uneven thickness of the electroplating layer. For example, when it is necessary to electroplate a ten-mm thick layer on the surface of the workpiece to be plated, due to the stability of current and voltage, the workpiece to be plated can be quickly and evenly plated to the required thickness, reducing the loss of electric energy. At the same time, it is conducive to uniform coating, and there will be no problem of extending the electroplating time due to the thickness of the coating not meeting the standard in some positions. Therefore, the electroplating efficiency is high. In addition, there will be no problem of wasting electroplating materials due to the excessive thickness of the coating in some positions, saving materials and reducing production costs. Due to the uniform thickness of the coating, the electroplating efficiency is also improved. The appearance of the finished workpiece is aesthetically pleasing; in addition, in this embodiment, since a rectifier with a dual output structure is used, metals 35 can be arranged at intervals on both sides of the workpiece to be plated, and one group of output copper bars on the rectifier on one side connects the workpiece to be plated and one of the metals 35, and the other group of output copper bars connects the workpiece to be plated and the other metal 35. Similarly, the rectifier on the other side also adopts the above-mentioned connection method, thereby accelerating the efficiency of electroplating and improving the quality of electroplating. In this field, the workpiece to be plated is usually clamped on the flying target 36; another implementation method is also given in this embodiment, that is, on the basis of the aforementioned implementation method, when the length of the workpiece to be plated is longer Or when the flying target 36 is long and clamps more workpieces to be plated, in order to ensure that the coating quality in the middle of the workpiece to be plated or on the workpiece to be plated in the middle of the flying target 36 meets the requirements, a rectifier can be set on one side of one of the long sides of the electroplating tank 34 to further ensure that the surface coating thickness of the workpiece to be plated is uniform; the control unit can adopt a host computer or a control head, and the control unit is connected to the rectifier signal through the R485 line. The function of the control head is the same as that of the host computer, and its main function is to adjust and control the working state of the rectifier, so as to realize the automation of the electroplating system and improve the electroplating efficiency. The control head itself and the host computer itself belong to the prior art.

[0047] In this embodiment, see Figure 8The electroplating system also includes an electroplating tank 34, the number of which is set according to actual production needs. All rectifiers are arranged around the electroplating tank 34, and at least one rectifier is arranged on one side of the wide side of the electroplating tank 34; one of the rectifiers is set as a host, and the remaining rectifiers are set as slaves. The rectifier set as the host is in a voltage stabilization mode, and the rectifier set as the slave is in a current stabilization mode. By setting the host and the slave, the current jump that causes poor coating quality can be avoided.

[0048] In the present embodiment, at the initial startup of the electroplating system, the rectifier set as the host outputs current, while the rectifier set as the slave does not output current; and the rectifier set as the host is preset with a specific output current value; the control unit collects the real-time output current values ​​of all rectifiers in real time, and the hardware for collecting the real-time output current values ​​is a current sensor 29, such as a Hall sensor, etc., and calculates the average current value of all rectifiers in real time. When the average current value is greater than the specific output current value of the host, the rectifier set as the slave starts to output current; in addition, since multiple rectifiers are connected in parallel, at the initial startup of the electroplating system, even if the rectifier as the slave does not output current, the rectifier as the slave will have current due to the current jump. Therefore, when calculating the average current value, the control unit needs to collect the real-time output current values ​​of all rectifiers.

[0049] The above electroplating system, because it has the above-mentioned rectifier, has all the beneficial technical effects brought by it; in addition, since at least one rectifier is arranged on the wide side of the electroplating tank 34, when the electroplating production line is a gantry line electroplating production line or a vertical line electroplating production line, the rectifier can be made as close to the electroplating tank 34 as possible to reduce power loss and improve electroplating quality; and at the initial startup of the electroplating system, the rectifier set as the host outputs current, while the rectifier set as the slave does not output current. At the same time, the rectifier set as the host is in voltage stabilization mode, and the rectifier set as the slave is in current stabilization mode. Only when the control unit calculates in real time that the average current value of all rectifiers is greater than the specific output current value of the host, the rectifier set as the slave starts to output current, thereby ensuring that all rectifiers can output stable current, and under the premise of current stabilization, the actual output current of all rectifiers is evenly distributed, thereby ensuring the stability of electroplating and the quality of electroplating.

[0050] In a preferred embodiment, the control unit identifies whether the rectifier set as the host is faulty through fault code identification and / or communication status. If the rectifier set as the host is judged to be faulty, the control unit will immediately set one of the rectifiers set as slaves as the host. Specifically, all rectifiers can be numbered. For example, if three rectifiers are used, each rectifier is coded with numbers ①, ②, and ③. Under the premise that all rectifiers are not faulty, the rectifier coded as ① is set as the host, and the rectifiers coded as ② and ③ are slaves. When the control unit detects that the rectifier as the host is faulty, the rectifier coded as ② is automatically set as the host in sequence to ensure the normal operation of the electroplating system. Among them, when the control unit identifies whether the rectifier as the host is faulty through the fault code, the control unit will monitor the various parameters and signals of the rectifier. When it detects that the host output current is abnormal or the current sensor 29 signal has a problem, the control unit will record the corresponding fault code. If a fault occurs multiple times or lasts for a period of time, the control unit will record it as a real fault; when the control unit identifies whether the rectifier as the host is faulty through the communication status, the control unit will monitor the communication signal, such as monitoring the LED display status information of the host or displaying the status through the PROFINET status word ZSW1.3, and analyze the communication data, that is, the control unit will analyze the received signals and data to determine whether the rectifier responds normally to instructions and feedback information. After the analysis, the fault code is diagnosed and diagnosed according to the preset fault code table to identify the specific fault type.
