Description

Technical Field

[0001] The present invention relates to the technical field of power supply equipment, and in particular to a pulse machine and a pulse control system. Background Art

[0002] Pulse technology is a device that uses electrical pulse signals to control its operation. It has a wide range of applications, such as in the field of electroplating. Compared with traditional electroplating, pulse plating can achieve better plating performance, such as uniformity of coating thickness, while reducing the total amount of electricity by regulating the pulse frequency and width of the current. This method is particularly suitable for precision electroplating operations that have high requirements for coating uniformity and microstructure. Pulse plating has significant advantages in deep hole plating. By precisely controlling the output of current, it can achieve a more uniform and dense metal coating; see Chinese patent CN110306214A, which discloses a reverse pulse copper plating process for through-hole electroplating of high aspect ratio aperture printed circuit boards, which uses pulse plating for deep hole electroplating.

[0003] However, a pulse machine is required to generate a pulse signal (i.e., output pulse power). Chinese patent CN214316049U discloses a high-frequency water-cooled pulse machine for electroplating of metal circuit boards, which is used to generate a pulse signal and provide a pulse power supply for pulse electroplating.

[0057] In this embodiment, see Figure 5-8, one end of the flexible conductive member 22 is connected to the conductive strip 9, and the other end is connected to the output aluminum plate 21, and the output aluminum plate 21 is connected to the second output copper bar 14. The flexible conductive member 22 is a soft copper strip, and the soft copper strip includes a first connection end and a second connection end, and the first connection end and the second connection end are connected through an intermediate connection portion, and the intermediate connection portion of the soft copper strip passes through the perforation in the middle of the magnetic core skeleton and the inner hole of the magnetic core 20, and the first connection end of the soft copper strip is connected to the output aluminum plate 21, and the second connection end is connected to the conductive strip 9 of the rectifier synchronous module assembly; the intermediate connection portion can be Z-shaped, such as Figure 7 and Figure 8 As shown, it is convenient to pass through the perforation in the middle of the magnetic core skeleton and the inner hole of the magnetic core 20 to avoid interference, and at the same time, the transformer assembly as a whole is more beautiful; of course, the intermediate connection portion can also be an arc, as long as the arc-shaped intermediate connection portion can pass through the perforation in the middle of the magnetic core skeleton and the inner hole of the magnetic core 20 without interfering with them, and the intermediate connection portion can also be formed by setting the first section and the second section in an angle state. The soft copper belt has good flexible connection performance and heat dissipation performance, that is: the soft copper belt is made of copper, which is a metal with good flexibility and can be bent multiple times without breaking, which makes the soft copper belt adaptable 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 belt 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 meet the needs of complex wire connection and circuit design; therefore, the transformer assembly is flexibly electrically connected to the synchronization module through the soft copper belt, 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.

[0058] In this embodiment, see Figure 5 and 6 A second heat dissipation assembly is connected in the second installation space and on the surface of the partition 5. The second heat dissipation assembly includes at least one second heat dissipation aluminum block 34. A plurality of second heat dissipation fins are vertically and spaced apart on the surface of the second heat dissipation aluminum block 34. In this embodiment, the second heat dissipation assembly includes two second heat dissipation aluminum blocks 34, which are spaced apart on the partition 5. By connecting the second heat dissipation assembly to the surface of the partition 5, heat can be dissipated for the power module, the pulse synchronous drive signal module, and the pulse total output module 2 in the first installation space and arranged on the partition 5.

[0059] The present invention also provides a specific implementation of a pulse control system, including at least two of the above-mentioned pulse machines, all of which are connected to the CAN bus signal, each pulse machine sends its own pulse timing to the CAN bus, the CAN bus performs timing synthesis according to the pulse timing of all received pulse machines, and obtains a timing synthesis signal, each pulse machine receives the timing synthesis signal, and adjusts its own pulse timing according to the timing synthesis signal. The timing synthesis signal is generated by the CAN bus in the pulse control system for all pulse machines to read, so that each pulse machine adjusts its own pulse timing according to the timing synthesis signal generated by the CAN bus, thereby ensuring the timing synchronization of each pulse machine, effectively avoiding the pulse machines from acting as loads to each other due to timing asynchrony, and avoiding mutual interference and damage to components. Since the pulse timing of all pulse machines can be ensured to be synchronized, when the pulse control system is used for electroplating, it can ensure that the coating on the electroplated parts is uniform and improve the quality of electroplating. Specifically, the pulse machine communicates with the CAN bus through the FPGA integrated chip in its internal pulse synchronization drive signal module, that is, the pulse machine sends its own pulse timing to the CAN bus through the FPGA integrated chip. After the CAN bus generates a timing synthesis signal, the FPGA integrated chip in the pulse machine reads the timing synthesis signal synthesized by the CAN bus and adjusts its own pulse timing, thereby ensuring the pulse timing synchronization of all pulse machines.

[0060] In a preferred embodiment, when all pulse machines are powered on but not turned on, the pulse synchronization drive signal module in the pulse machine communicates with the CAN bus in real time, and adjusts the timing of its own pulse drive signal in real time according to the received timing synthesis signal until the timing of its own pulse drive signal is completely synchronized with the timing of the synthesis signal on the CAN bus, preparing for turning on and outputting pulse power.

[0061] In a preferred embodiment, after all pulse machines are turned on, the pulse synchronization drive signal module in the pulse machine communicates with the CAN bus in real time, and the pulse synchronization drive signal module in each pulse machine continuously compares its own pulse timing during the pulse power supply output period with the timing synthesis signal synthesized by the CAN bus. When the comparison result between the two is not synchronized, the pulse synchronization drive signal module in the pulse machine adjusts the pulse timing according to the timing synthesis signal synthesized by the CAN bus.
