Description

Technical Field

[0001] This utility model relates to the field of PCB board assembly technology, specifically to an automatic assembly mechanism for power adapter PCB boards. Background Technology

[0002] A power adapter is a common power conversion device, mainly used to convert AC mains power into low-voltage DC power required by electronic devices. It typically consists of a casing, transformer, rectifier circuit, and filter components, and has functions such as voltage regulation and overcurrent protection. It is widely used in digital products such as laptops, mobile phones, and routers, enabling them to work stably under safe voltage. Adapters are divided into built-in and external types, with power ranging from a few watts to hundreds of watts. When selecting one, it is necessary to pay attention to matching the output parameters with the device to avoid damage. A power adapter generally consists of components such as a casing, transformer, inductor, capacitor, control IC, and PCB board. Its working principle is to convert AC input to DC output.

[0003] PCB boards and connectors are often fixed by welding. Welded connections have advantages such as high connection strength and strong structural stability. However, when welding components on the PCB board, single-sided welding can lead to poor solder joint consistency, serious flux residue, and a significant reduction in product reliability and lifespan. Therefore, after welding components to the PCB board surface on one side, the PCB board needs to be manually disassembled and then fixed again. The components then need to be flipped over for secondary welding, resulting in low efficiency. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] See attached document Figures 1-4 An automatic assembly mechanism for a power adapter PCB board includes a mounting frame 1, a fixing frame 2 fixedly mounted on the top of the mounting frame 1, a welding head 3 mounted on the top of the fixing frame 2, a fixing frame 4 set on the top of the mounting frame 1, a rotating frame 5 set inside the fixing frame 4, a rotating shaft 6 mounted on both the front and back of the rotating frame 5, a first drive motor 7 set on the front of the fixing frame 4, the first drive motor 7 connected to the rotating shaft 6, and a limiting mechanism installed on the inner wall of the rotating frame 5. The limiting mechanism can restrict the PCB board into the rotating frame 5, so that the first drive motor 7 can drive the rotating frame 5 to rotate after starting, so as to adjust the orientation of the PCB board after the rotating frame 5 is rotated for welding processing, thereby improving the efficiency and stability of the workpiece.

[0026] See attached document Figures 1-3The limiting mechanism includes a limiting seat 8, which is fixedly installed on the inner wall of the rotating frame 5. A limiting groove 9 is formed at the top of the limiting seat 8. A movable plate 13 is provided at the top of the limiting seat 8, and a limiting block 11 is fixedly installed at the bottom of the movable plate 13. The limiting block 11 engages with the limiting groove 9. Movable grooves 12 are formed on both sides of the rotating frame 5. Movable plates 13 are slidably installed on the inner walls of the movable grooves 12. Movable plates 14 are provided on both sides of the rotating frame 5. The movable plates 13 are installed on the sides of the movable plates 14. The movable plates 14 can be moved upwards to separate the limiting block 11 from the limiting groove 9, facilitating the movement of the PC. The B board is placed between the limiting seats 8, which allows the limiting seats 8 to support the PCB board. This facilitates the downward movement of the limiting block 11 to restrict the PCB board. The movable plate 13 slides in the moving groove 12, which restricts the movement of the movable plate 14. A spring is fixedly installed on the top of the limiting block 11, and the top of the spring is fixedly connected to the top of the inner wall of the moving groove 12. This allows the spring to press against the movable plate 13, causing the movable plate 13 to drive the limiting block 11 downward through the moving plate 14 and the limiting plate 10. This facilitates the use of the limiting plate 10 to block and restrict the PCB board.

[0027] See attached document Figure 1 The mounting frame 1 has a first side frame 15 and a second side frame 16 mounted on its front and rear sides respectively. A second drive motor 36 is mounted on the front of the first side frame 15. A drive wheel set 17, a driven wheel set 19, and a support wheel set 18 are rotatably mounted between the first side frame 15 and the second side frame 16. The drive wheel set 17, the support wheel set 18, and the driven wheel set 19 are arranged from right to left. A transmission belt 20 is provided between the first side frame 15 and the second side frame 16. The transmission belt 20 is sleeved on the surface of the drive wheel set 17, the driven wheel set 19, and the support wheel set 18. The fixed frame 4 is mounted on the surface of the transmission belt 20. By starting the second drive motor 36, the second drive motor 36 drives the drive wheel set 17 to rotate, so that the drive wheel set 17 drives the transmission belt 20, which in turn facilitates the movement of the fixed frame 4. The driven wheel set 19 and the support wheel set 18 support the transmission belt 20, so that the fixed frame 4 can be moved, which facilitates the transport of the PCB board for processing.

[0028] See attached document Figures 1-2A movable seat 21 is installed at the bottom of the first drive motor 7. A sliding block 22 is fixedly installed on the back of the movable seat 21. A sliding frame 23 is fixedly installed on the front of the first side frame 15. The sliding block 22 is slidably connected to the sliding frame 23. The sliding block 22 can move in the sliding frame 23. This not only moves the first drive motor 7 installed on the movable seat 21, but also allows the transmission belt 20 to move the first drive motor 7 and the movable seat 21 when it moves the fixed frame 4. A mounting hole 24 is opened on the front of the movable seat 21 and extends through to the back of the sliding block 22. A limiting hole 25 is opened on the inner wall of the sliding frame 23. A mounting ring 26 is fixedly installed on the front of the movable seat 21. A rotating rod 27 is threaded on the inner wall of the mounting ring 26. A limiting rod 28 is rotatably installed at the end of the rotating rod 27. When the rotating rod 27 is rotated, it can be driven to move backward, so that the rotating rod 27 drives the limiting rod 28 to be inserted into the limiting hole 25 to limit the movable seat 21.

[0029] See attached document Figures 1-4 A liquid storage tank 29 is installed on the left side of the mounting frame 1. A partition 30 is fixedly installed on the bottom of the inner wall of the liquid storage tank 29. Delivery pipes are installed on both sides of the inner wall of the liquid storage tank 29. Support plates 31 are installed on both sides of the inner wall of the liquid storage tank 29, and the support plates 31 are mounted on the surface of the delivery pipes. A spray pipe 32 is connected to the top of the delivery pipe 32, and several nozzles are connected to the top of the spray pipe 32. Mounting boxes 33 are installed on both sides of the bottom of the inner wall of the liquid storage tank 29. A water pump 34 is installed on the top of the mounting box 33. The output end of the water pump 34 is connected to the delivery pipe, and the input end of the water pump 34 is connected to the mounting box 33. A partition plate 30 is installed on the inner wall of the mounting box 33. The filter layer 35 can separate the storage tank 29 through the partition 30 to store cleaning solution and pure water respectively. After the water pump 34 is started, it sprays out from the nozzle through the delivery pipe and the spray pipe 32. The cleaning solution can be used to spray and clean the PCB board. After the PCB board is continuously delivered to the pure water, the residual stains and cleaning solution on the PCB board surface can be cleaned. This avoids the residue of flux, dust or solder balls on the PCB board surface, which may cause circuit leakage, corrosion or short circuit. The installed filter layer 35 can filter impurities in the cleaning solution and pure water in the storage tank 29 to prevent impurities from being transported and reused and sprayed on the surface of the PCB board.

[0030] Working principle: Pulling the movable plate 14 upward causes it to move upward through the limiting plate 10, causing the limiting block 11 to separate from the limiting slot 9. This allows the PCB board to be placed inside the rotating frame 5, with the notch on the side of the PCB board positioned at the limiting seat 8. Then, the movable plate 14 is released, causing the spring to compress the movable plate 13, which in turn moves the movable plate 14 downward. As the movable plate 14 moves downward, the limiting plate 10 causes the limiting block 11 to insert into the limiting slot 9. This allows the limiting plate 10 and the limiting seat 8 to clamp and restrict the PCB board, facilitating the soldering of components onto the PCB surface using the soldering head 3. After soldering components on one side, the first drive motor 7 is started, causing it to drive the rotating shaft 6... The rotating frame 5 rotates, allowing the PCB board to be flipped over and the components to be spot-welded and fixed again. Then, the second drive motor 36 is started, which drives the drive wheel set 17 to rotate, thereby driving the transmission belt 20 to rotate. The transmission belt 20 moves the fixed frame 4, rotating it above the liquid storage tank 29. After the water pump 34 in the cleaning liquid is started, the cleaning liquid is drawn out and sprayed from the nozzle to clean the flux, dust, or solder balls remaining on the PCB board surface. After cleaning the PCB board with the cleaning liquid, the PCB board is transported to the left side of the partition 30, where pure water is transported to clean the remaining cleaning liquid, ensuring the quality of the finished PCB board.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
