Description

Technical Field

[0001] This utility model belongs to the field of rectifier power supply technology, and in particular relates to a novel high-frequency electroplating power supply. Background Technology

[0002] Electroplating power supplies are specialized industrial equipment that achieves electroplating treatment on metal surfaces through current control. They can realize constant voltage / constant current output, current commutation and ripple control, and are widely used in fields such as strengthening aerospace components, corrosion protection of automotive parts, and plating of electronic product contacts.

[0003] Existing electroplating power supplies mainly consist of a chassis and a main control unit installed inside the chassis. The chassis is equipped with heat sinks and a fan. Heat is drawn from the main control unit through the heat sinks, and the heat is dissipated from the heat sinks by the fan, thereby achieving heat dissipation of the main control unit, ensuring that the electroplating power supply can operate for a long time and improving work efficiency.

[0004] However, in actual use, it was found that when the electroplating power supply is not working, the fan will turn off, but the ventilation openings on the chassis will still be exposed, making it very easy for external dust to enter the chassis and accumulate on the main control unit. This not only hinders the normal heat dissipation of the main control unit and affects its working performance, but also easily causes poor contact in the main control unit circuit, shortening its service life. In view of this, it is necessary to design a new high-frequency electroplating power supply to solve this problem. Utility Model Content

Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0037] See appendix Figure 1 -Appendix Figure 12A novel high-frequency electroplating power supply includes a chassis 1, a control board 2, a main control unit 3, a heat dissipation section 4, and a shielding section 5. The chassis 1 has an internal cavity 10 for mounting the control board 2 and the main control unit 3. A ventilation opening 11 for connecting to the outside is provided on the side wall of the cavity 10. The control board 2 and the main control unit 3 are electrically connected to each other. The heat dissipation section 4 includes a mounting shell 41, heat sinks 42, and a fan 43. The mounting shell 41 is installed inside the cavity 10 and isolates an independent air chamber 411. An air guide vent 412 is provided on the side wall of the air chamber 411. The heat sink 42 is disposed within the cavity 10. It contacts the main control unit 3, and the heat sink 42 connects the receiving cavity 10 and the air vent 412. The fan 43 is mounted on the chassis 1 and electrically connected to the control board 2. The fan 43 is connected to the ventilation cavity 411 and the outside. The shielding part 5 includes a first baffle 51, a second baffle 52 and a drive assembly 53. The first baffle 51 is movably mounted next to the ventilation vent 11, and the second baffle 52 is movably mounted next to the air vent 412. The drive assembly 53 is mounted on the chassis 1 and can synchronously drive the first baffle 51 and the second baffle 52 to open and close the ventilation vent 11 and the air vent 412 respectively.

[0038] Specifically, during operation, the first baffle 51 and the second baffle 52 are driven synchronously by the drive component 53 to open the ventilation port 11 and the air guide port 412 respectively. The heat generated by the operation of the main control unit 3 is conducted to the heat sink 42. When the fan 43 is started, the heat at the heat sink 42 can be exhausted to the outside through the ventilation port 11 and the air guide port 412.

[0039] After the work is completed, first turn off the fan 43, and then drive the first baffle 51 and the second baffle 52 simultaneously through the drive component 53 to close the ventilation port 11 and the air guide port 412 respectively, so as to seal the chassis 1 and prevent external dust from entering the housing cavity 10.

[0040] In summary, this utility model provides a heat dissipation section 4, consisting of a fixed shell 41, a heat sink 42, and a fan 43, to guide and dissipate the heat generated by the main control unit 3, ensuring that the high-frequency electroplating power supply can operate for a long time and improving work efficiency. Furthermore, by providing a shielding section 5, consisting of a first baffle 51, a second baffle 52, and a drive assembly 53, to simultaneously open and close the ventilation opening 11 and the air guide 412, the chassis 1 is sealed when not in operation, reducing the amount of dust entering the chassis 1. This reduces the possibility of dust contaminating the main control unit 3 and causing a series of problems, ensuring the working performance of the main control unit 3 and extending its service life.

[0041] It should be noted that there are two ways to use the fan 43: the first is to draw gas from the receiving cavity 10. In this process, outside gas is drawn into the receiving cavity 10 through the vent 11. After the gas carries heat and enters the air chamber 411 through the air guide 412, it is finally drawn out of the outside by the fan 43. The second is to blow gas into the air chamber 411. The gas in the air chamber 411 carries heat and enters the receiving cavity 10 after passing through the air guide 412, and finally overflows from the vent 11 to the outside. Since there are multiple ways to use it, this utility model does not limit it. On the other hand, the control board 2 and the main control unit 3 are both existing technologies and are of various types. This utility model does not limit them here.

[0042] See appendix Figure 3 -Appendix Figure 4 and attached Figure 7 -Appendix Figure 12 The first baffle 51 is slidably mounted on the side wall of the receiving cavity 10, and the first baffle 51 is provided with a pressing block 510 having an inclined edge 511 and abutment 512; the second baffle 52 is slidably mounted on the fixed shell 41, and the second baffle 52 is provided with abutment 520 having an inclined section 521 and a straight section 522; the driving assembly 53 includes a driving source 531 and a first elastic member 532. The driving source 531 is installed in the receiving cavity 10 and drivenly connected to the first baffle 51. The first elastic member 532 is disposed on the fixed shell 41 and connects the side wall of the fixed shell 41 and the second baffle 52; wherein, the inclined edge 511 can abut against the inclined section 521 and slide, and the abutment 512 can abut against the straight section 522 and slide, so that the first baffle 51 can synchronously drive the second baffle 52, and when the abutment 512 slides on the straight section 522, the second baffle 52 closes the air guide port 412, and the first elastic member 532 deforms and stores energy.

[0043] Specifically, when the abutment 512 abuts against the straight section 522 and is located at the end of the straight section 522, the first baffle 51 and the second baffle 52 respectively close the vent 11 and the air guide 412, and the first elastic element 532 deforms and stores energy. When the first baffle 51 is driven to slide open the vent 11 by the drive source 531, the abutment 512 moves along the straight section 522. At this time, the second baffle 52 still closes the air guide 412, and the first elastic element 532 is still in the deformed and stored energy state until the abutment 512 leaves the straight section 522. The first elastic element 532 releases energy and recovers to drive the second baffle 52 to slide and gradually open the air guide 412, so that the inclined section 521 of the block contacts the inclined edge 511 of the pressure block 510. In this case, if the first baffle 51 is moved further, the pressure block 510 will move away from the baffle and contact the first elastic element 532 to push the second baffle 52 open and open the air guide 412.

[0044] When the first baffle 51 is driven by the drive source 531 to slide and close the vent 11, the first baffle 51 drives the inclined edge 511 of the pressure block 510 to apply pressure to the inclined section 521 of the block, which in turn squeezes the second baffle 52 to gradually close the air guide 412 until the inclined edge 511 of the pressure block 510 disengages from the inclined section 521 of the block and the abutment 512 of the pressure block 510 contacts the straight section 522 of the block. Then the second baffle 52 completely closes the air guide 412, and the first elastic element 532 deforms and stores energy again. At this time, the first baffle 51 can be moved to completely close the vent 11. In this case, the abutment 512 continues to contact the straight section 522, so the second baffle 52 keeps the air guide 412 closed.

[0045] In summary, the cooperation between the inclined edge 511 and the abutment 512 of the pressure block 510 and the inclined section 521 and the straight section 522 of the stop block, as well as the combined use of the first elastic element 532 and the drive source 531, enables the synchronous driving of the first baffle 51 and the second baffle 52 to be completed by the drive source 531 alone, saving costs and improving operational convenience.

[0046] See appendix Figure 11 -Appendix Figure 12 The abutment block 520 is provided with a guide groove 5200. The inclined section 521 and the straight section 522 are both set in the guide groove 5200. The inclined edge 511 and the abutment 512 of the pressure block 510 extend into the guide groove 5200 and abut against the inclined section 521 and the straight section 522 respectively. The design of the guide groove 5200 can restrict the inclined edge 511 and the abutment 512 of the pressure block 510, and prevent them from disengaging from the corresponding inclined section 521 and straight section 522 during the sliding process of the pressure block 510, thereby improving the structural stability.

[0047] See appendix Figure 3 -Appendix Figure 4 and attached Figure 7 -Appendix Figure 10 The second baffle 52 is located inside the air cavity 411. A horizontally arranged movable groove 4110 is provided on the side wall of the air cavity 411. The pressure block 510 passes through the movable groove 4110 and contacts the abutment block 520. The pressure block 510 can slide along the movable groove 4110. The inner wall of the air cavity 411 is also provided with a fastening bolt 413. The second baffle 52 is also provided with a fastening buckle 523. The two ends of the first elastic member 532 are respectively connected to the fastening bolt 413 and the fastening buckle 523.

[0048] Specifically, the second baffle 52 is located in the air cavity 411 and has a larger space for movement, and can prevent the heat sink 42 from obstructing the sliding of the second baffle 52. The movable groove 4110 is an adaptive design to ensure that the pressure block 510 can be properly inserted into the air cavity 411 and contact the abutment block 520. The fastening bolt 413 and the fastening buckle 523 are used to fix the first elastic member 532, so that the two ends of the first elastic member 532 are connected to the fixed shell 41 and the second baffle 52.

[0049] See appendix Figure 3 -Appendix Figure 4 and attached Figure 7 -Appendix Figure 12 Considering that when the first baffle 51 and the second baffle 52 completely close the ventilation opening 11 and the air guide 412, due to structural limitations, the pressure block 510 cannot completely close the movable groove 4110. Therefore, some dust will still enter the air cavity 411 through the fan 43 and eventually pass through the movable groove 4110 into the receiving cavity 10. To solve this problem, in this utility model, the shielding part 5 also includes a shield 54. The inner wall of the air cavity 411 is provided with a limiting seat 414 with a slider 4140 on the side of the movable groove 4110. The shield 54 is provided with a sliding groove 540 that slides with the slider 4140, and the sliding groove 540 has a second elastic member 542 that abuts against the shield 54 and the limiting seat 414. The top of the shield 54 The shield 54 is horizontally arranged and has a pressure-bearing end 541 with a first inclined surface 5410. The bottom surface of the pressure block 510 is horizontally arranged and has a notch 513 with a second inclined surface 5130. When the first baffle 51 closes the ventilation opening 11, the pressure-bearing end 541 is placed in the notch 513 and the first inclined surface 5410 is parallel to and attached to the second inclined surface 5130. When the first baffle 51 is slid to open the ventilation opening 11, the second inclined surface 5130 squeezes the first inclined surface 5410 and drives the pressure-bearing end 541 to disengage from the notch 513, while the second elastic element 542 deforms and stores energy. After the bottom surface of the pressure block 510 is attached to the top surface of the shield 54, the pressure block 510 can slide along the movable groove 4110.

[0050] Specifically, when the abutment 512 abuts against the straight section 522 and is located at the end of the straight section 522, the pressure end 541 is placed in the notch 513 and the first inclined surface 5410 is parallel to and in contact with the second inclined surface 5130. The second elastic element 542 is in the initial state so that the shield 54 closes the exposed part of the movable groove 4110. When the sliding first baffle 51 causes the abutment 512 of the pressure block 510 to slide along the straight section 522, the second inclined surface 5130 in the notch 513 on the pressure block 510 presses the first inclined surface 5410 and drives the pressure end 541 to disengage from the notch 513. After the bottom surface of the pressure block 510 is in contact with the top surface of the shield 54, the pressure block 510 can continue to slide along the movable groove 4110 until the first baffle 51 fully opens the ventilation port 11, and the second elastic element 542 is squeezed by the lowered shield 54 and deforms to store energy.

[0051] Similarly, when the sliding first baffle 51 closes the vent 11 again, causing the abutment 512 to return to the end of the straight segment 522, the second elastic element 542 releases energy and restores its function, causing the shield 54 to reset and reclose the exposed part of the movable groove 4110.

[0052] In summary, the combined use of the shield 54, the limiting seat 414, the second elastic element 542 and the pressure plate ensures that when the first baffle 51 and the second baffle 52 completely close the ventilation opening 11 and the air guide 412, the movable groove 4110 can be completely closed, thereby preventing dust from entering the receiving cavity 10.

[0053] See appendix Figure 9 -Appendix Figure 12 The abutment block 520 is also provided with a clearance opening 524. When the second baffle 52 opens the air duct 412, part of the shield 54 enters the clearance opening 524. When the installation structure of the first baffle 51 and the second baffle 52 is relatively compact, this design can avoid the abutment block 520 from blocking the air duct 412, which would prevent the second baffle 52 from fully opening the air duct 412.

[0054] See appendix Figure 3 -Appendix Figure 4 and attached Figure 7 -Appendix Figure 12 The driving source 531 can be a manual driving mechanism or an electric driving mechanism. This utility model does not limit this. For ease of understanding, the driving source 531 in this embodiment is a cylinder. The cylinder body is fixed on the side wall of the receiving cavity 10, and the telescopic end of the cylinder is driven to connect with the first baffle 51. By controlling the extension and retraction of the telescopic end of the cylinder, the first baffle 51 can be slid. The first elastic element 532 and the second elastic element 542 can be elastic components such as rubber sleeves and springs. Due to the variety of types, this utility model does not limit this. For ease of understanding, in this embodiment, the first elastic element 532 is a first spring. The two ends of the first spring are respectively connected to the second baffle 52 and the side wall of the fixed shell 41. The second elastic element 542 is a second spring. The two ends of the second spring abut against the limiting seat 414 and the cover 54, respectively.

[0055] See appendix Figure 1 -Appendix Figure 7 The control board 2 is also electrically connected to a power connector 20 mounted on the chassis 1. The main control unit 3 includes a high-voltage board 31, a rectifier 32 and a high-frequency transformer 33 mounted on a heat sink 42. The high-voltage board 31 is electrically connected to the control board 2, the rectifier 32 and the high-frequency transformer 33. The high-voltage board 31 and the high-frequency transformer 33 are also electrically connected to power-conducting pins 310 that pass through the chassis 1 to the outside.

[0056] Specifically, the power connector 20 is used to connect an external power source. The current flows through the control board 2 to the high-voltage board 31, and is rectified and inverted by the rectifier 32 and the high-frequency transformer 33. Finally, the current is output through the power-on pin 310. The structure of the control board 2, the high-voltage board 31, the rectifier 32, the high-frequency transformer 33, the power connector 20, and the power-on pin 310 is used in conventional electroplating power supplies. In other electroplating power supplies, there are even protection devices, detection devices, and other components. Since the relevant structural components are all existing technologies, the specific circuit structure and working principle are not described in detail in this utility model.

[0057] See appendix Figure 1 -Appendix Figure 7 The present invention also includes an interactive unit 6, which is electrically connected to the control board 2 and includes a display screen 61, an emergency stop switch 62 and a master control switch 63 mounted on the outer wall of the chassis 1.

[0058] Specifically, the display screen 61 can be used to display relevant data information such as voltage and current of the main control unit 3, the emergency stop switch 62 is used for emergency braking, and the master control switch 63 is used to control the connection and disconnection of the overall circuit. The relevant structural components are relatively conventional in electronic devices such as electrical control boxes, and their specific circuit structure and working principle will not be further described in this utility model.

[0059] Furthermore, a waterproof cover (not shown in the illustration) for the user to close the main control switch 63 can be installed on the chassis 1, and the power connector 20 can also be waterproofed.

[0060] See appendix Figure 1 -Appendix Figure 6 The bottom of the chassis 1 has a cavity 12, in which the fan 43 and the power connector 20 are located. The side wall of the cavity 12 also has a through groove 120 that connects to the outside. This design allows the fan 43 to be suspended and connected to the outside through the through groove 120, which facilitates the fan 43 to draw in or blow out air, thus improving the operating stability of the fan 43. On the other hand, it allows the user to pass the power cord through the through groove 120 before connecting it to the power connector 20. The through groove 120 supports the power cord and prevents it from touching the ground and wearing out. It also improves the overall aesthetics.

[0061] See appendix Figure 1 -Appendix Figure 6 The bottom of the chassis 1 is also equipped with multiple casters 13 that contact the ground, which improves the overall ease of movement.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
