Description

Technical Field

[0001] The present invention relates to the technical field of power adapter production, and particularly to a modular power adapter circuit quick docking and welding system. Background Art

[0002] In today's digital age, as a key power supply component for various electronic devices, the production and manufacturing process of power adapters is self-evidently important. In the entire production process, the welding link between the power cord and the circuit board is particularly crucial, and the welding quality directly determines the electrical performance and use safety of the product.

[0003] Among the diverse power adapter products, there is a type of small power adapter with a relatively special circuit board design. This type of circuit board has only two welding points for connecting the power cord, and these two welding points are arranged in a straight line and are distributed near the central symmetry position of the circuit board.

[0004] Currently, when many small production enterprises weld the power cord for such a specific circuit board, they mainly use manual welding or semi-automatic welding methods. During the manual welding process, due to the special position of the welding points, the operator must spend a lot of time to accurately align the welding points. This operation is not only cumbersome but also greatly slows down the production progress, resulting in extremely low overall production efficiency. Moreover, the quality of manual welding depends heavily on factors such as the technical level, work experience, and fatigue state of the welding personnel during work. There are obvious differences in the control of welding temperature, welding time, and solder consumption among different operators, which makes the welding quality fluctuate greatly and it is difficult to ensure stable product quality.

[0005] Although semi-automatic welding makes use of mechanical assistance to a certain extent, when facing such a special welding point layout, it still cannot efficiently and accurately complete the alignment of the power cord and the welding points, and there is also the problem of low production efficiency. Summary of the Invention

[0019] The beneficial effects of a modular power adapter circuit quick docking and welding system of the present invention:

[0020] 1. Efficient clamping and positioning of the circuit board. Through the coordinated work of the fixing frame, the driving rod, the clamping assembly, etc., only need to place the circuit board solder joints facing correctly on the top of the fixing frame. The driving rod pulls the connecting rod, drives the push plate and the top plate to move. The top plate squeezes the docking bolt through the inclined surface, so that the movable rod drives the clamping plates to move relatively, and can quickly clamp and lift the circuit board in the center, avoiding the problem of uneven placement caused by the pins on the back of the circuit board. The whole process is simple and efficient, greatly saving the circuit board positioning time and improving the production efficiency.

[0021] 2. Precise power cord docking and welding. The fixed frame, movable plate, pushing component, alignment module, etc. in the docking mechanism cooperate with each other. Before welding, according to the position and spacing of the welding points, the position of the alignment module can be adjusted through the driving component, and the spacing of the docking components can be precisely controlled by the adjusting component. When the power cord is inserted into the socket, the pushing component pushes the alignment module to drop, and the driving component drives the connecting arm to separate the docking components, while clamping the power cord to ensure that the end of the power cord is precisely aligned with the welding point. Subsequently, the welding head drops to complete the welding. The entire process realizes the high-precision docking and welding of the power cord and the welding point, ensuring the welding quality.

[0022] 3. Adapt to different welding point layouts. The structural design of the sleeve, adjusting ring, adjusting rod, and clamping block of the adjusting component is ingenious. By rotating the position of the adjusting ring on the sleeve, the length of the adjusting rod pulled out can be restricted, so as to flexibly control the spacing between the docking components, and can quickly adapt to the different distances between two welding points on different small power adapter circuit boards, enhancing the versatility and applicability of the welding system.

[0023] 4. Protect the welding components and stabilize the welding process. During the clamping process of the circuit board, if the clamping plate completes the clamping while the pushing plate stroke is not over, the driving force of the top plate will act on the spring, avoiding the continuous increase of the clamping force of the clamping plate and preventing damage to the circuit board. During the welding process, the elastic component, pressing block, stop block, etc. cooperate with each other. For example, when the welding head drops, the pressing surface squeezes the stop block to separate it, ensuring the smooth progress of welding, and at the same time, it can play a role in stabilizing and protecting the power cord during the welding process, further improving the welding quality and the reliability of the equipment.

[0044] The fixing mechanism 21 includes a fixing frame 211 fixedly connected to the inner wall of the main body 1;

[0045] The docking mechanism 22 includes a fixing frame 221 arranged inside the main body 1 near the fixing frame 211. A movable plate 222 is slidably connected inside the fixing frame 221.

[0046] The alignment module 225 includes a fixing rod 2257 fixedly installed at the bottommost part inside the inner side of the activity groove 2241. A limiting groove 22571 is opened on the outer wall of the fixing rod 2257, and a docking component 2258 is arranged inside the limiting groove 22571. Limiting rods 2254 are fixedly connected to the tops of both ends of the fixing rod 2257. A pressing plate 22522 is slidably connected to the outer walls of the limiting rods 2254.

The bottom end of the push rod 2252 penetrates through the driving plate 2253 and is fixedly connected to the pressing plate 22522. An elastic member two 22521 is sleeved on the outer wall of the push rod 2252 between the activity frame 224 and the driving plate 2253. A connecting arm 2255 is hinged to the bottom of the driving plate 2253, and the bottom end of the connecting arm 2255 is hinged to the docking component 2258. An adjusting component 2256 is arranged between the two connecting arms 2255;

[0047] A driving component one 2211 is arranged at the position of the movable plate 222 inside the fixing frame 221. The driving component one 2211 is used to drive the movable plate 222 to move horizontally inside the fixing frame 221. A pushing component 223 is arranged on the top of the movable plate 222. The output end of the pushing component 223 penetrates through the movable plate 222 and is fixedly connected to the activity frame 224.

[0048] By adopting the above technical solution, the fixing frame 221 provides a sliding track for the movable plate 222, and the movable plate 222 realizes horizontal movement through the pushing component 223. The movable slot 2241 opened inside the movable frame 224 is used to install the alignment module 225 to ensure the precise docking of the power cord and the circuit board solder joint. The limiting slot 22571 on the fixing rod 2257 is used to install the docking component 2258 and at the same time provide a guiding function. The pressing plate 22522 and the driving plate 2253 slidably connected to the limiting rod 2254 realize the precise control of the docking component 2258 through the linkage of the pushing rod 2252 and the second elastic member 22521. The connecting arm 2255 is hinged between the bottom of the driving plate 2253 and the docking component 2258 and is used to transmit the driving force and adjust the position of the docking component 2258.

[0049] A chute one 2111 is opened near one side of the top of the fixing frame 211, and a chute two 2112 is opened near the other side of the top of the fixing frame 211. A clamping component 213 is arranged inside the fixing frame 211. The clamping component 213 includes a mounting seat one 2131, and the mounting seat one 2131 is fixedly installed at a position inside the fixing frame 211 near the chute two 2112. A mounting seat two 2134 is fixedly connected at a position inside the fixing frame 211 near the chute one 2111. One end of the mounting seat one 2131 away from the mounting seat two 2134 is slidably connected with a push plate 2132. The center position of one side of the bottom of the push plate 2132 near the mounting seat one 2131 is fixedly connected with a connecting rod 2133. One end of the connecting rod 2133 away from the mounting seat one 2131 penetrates through the mounting seat two 2134 and the fixing frame 211 and is slidably connected with the two. A driving rod 212 is arranged at the bottom of the outside of the fixing frame 211, and the output end of the driving rod 212 is fixedly connected with the connecting rod 2133. A top plate 2135 is fixedly connected to the outer wall of the connecting rod 2133 near the mounting seat two 2134.

[0050] By adopting the above technical solution, the push plate 2132 is slidably connected to one end of the mounting seat one 2131 away from the mounting seat two 2134 and can move freely in the chute one 2111 and the chute two 2112. The top plate 2135 is fixedly connected to the outer wall of the connecting rod 2133 near the mounting seat two 2134, moves together with the connecting rod 2133, and interacts with other components of the clamping component 213 during the movement to realize the clamping of the circuit board. The driving rod 212 is arranged at the bottom of the outside of the fixing frame 211, and its output end is fixedly connected with the connecting rod 2133. When the driving rod 212 is started, the connecting rod 2133 is pushed to move through the output end, and then the components such as the push plate 2132 and the top plate 2135 work together to realize the clamping and fixing of the circuit board.

[0051] Both ends of the second mounting base 2134 are slidably connected with movable rods 2136. A sliding rod 21362 is slidably connected to the opposite sides of the two movable rods 2136. A clamping plate 21363 is fixedly connected to the opposite ends of the sliding rod 21362. A first spring 21364 is arranged outside the sliding rod 21362 between the clamping plate 21363 and the movable rod 2136. An elastic member 21361 connected to the fixed frame 211 is arranged on the side of the movable rod 2136 away from the clamping plate 21363. A docking bolt 21365 is slidably connected inside one end of the movable rod 2136 close to the top plate 2135. The docking bolt 21365 is slidably connected with the top plate 2135. The top end of the push plate 2132 extends outside the fixed frame 211 through the second chute 2112. The top of the clamping plate 21363 extends outside the fixed frame 211 through the first chute 2111. And a top surface 21366 is provided at the position of the clamping plate 21363 inside the fixed frame 211 and close to the first chute 2111.

[0052] By adopting the above technical solution, a clamping plate 21363 is fixedly connected to the opposite ends of the sliding rod 21362. When the sliding rod 21362 moves, it will drive the clamping plate 21363 to move together, so as to realize the clamping of the circuit board. The docking bolt 21365 is slidably connected inside one end of the movable rod 2136 close to the top plate 2135 and is also slidably connected with the top plate 2135 at the same time. When the top plate 2135 moves, it will drive the movement of the movable rod 2136 and the clamping plate 21363 by squeezing the docking bolt 21365. The design of the top surface 21366 enables the clamping plate 21363 to lift the circuit board to a certain height when clamping the circuit board, avoiding the pins on the back of the circuit board from affecting its horizontal placement.

[0053] The adjusting component 2256 includes a sleeve 22561 fixedly connected to one of the connecting arms 2255. Threads are provided on the circumferential outer wall of the sleeve 22561. An adjusting ring 22563 is threadedly connected to the outer wall of the sleeve 22561. Adjusting grooves 22562 are uniformly penetrated through the circumferential outer wall of the sleeve 22561. An adjusting rod 22564 is slidably connected inside the sleeve 22561. One end of the adjusting rod 22564 is fixedly connected to the other connecting arm 2255. A clamping block 22565 is arranged at one end of the adjusting rod 22564 close to the sleeve 22561. The clamping block 22565 extends outside the sleeve 22561 through the adjusting groove 22562. The docking component 2258 includes a mounting rod 22581 slidably connected to the bottom of the fixed rod 2257. The bottom end of the connecting arm 2255 is hinged to the mounting rod 22581. One end of the mounting rod 22581 penetrates through the movable frame 224 and is slidably connected. There are two mounting rods 22581 in total. Sockets 22582 are provided at the bottom of the two mounting rods 22581 close to each other. A pressing block 22583 is slidably connected at the upper position inside the socket 22582. A fourth spring 225833 connected to the mounting rod 22581 is arranged inside the pressing block 22583.

[0054] By adopting the above technical solution, the mounting rod 22581 is slidably connected to the bottom of the fixed rod 2257, and at the same time, its bottom end is hinged to the connecting arm 2255, so that the docking assembly 2258 can be separated or approached under the push of the connecting arm 2255. Before welding, by rotating the adjusting ring 22563 to adjust its position on the sleeve 22561, the length of the adjusting rod 22564 pulled out is limited, and further the distance between the two mounting rods 22581 (i.e., the docking assembly 2258) is controlled to ensure that they can be accurately aligned with the welding points on the circuit board. During the welding process, when the docking assembly 2258 is separated under the push of the connecting arm 2255, the pressing block 22583 will also move accordingly, and under the action of the fourth spring 225833, it will maintain the clamping force on the power cord to prevent the power cord from detaching or displacing.

[0055] The top end of the pressing block 22583 extends into the limiting groove 22571 and is slidably connected to the welding head 22584. A second spring 225832 is arranged at the top end of the pressing block 22583 inside the top welding head 22584. A notch 22572 is formed at the bottom of the fixed rod 2257 near the pressing block 22583. A first pressing surface 225831 is arranged on the outer wall of the pressing block 22583 corresponding to the notch 22572. A blocking block 22585 is slidably connected inside the mounting rod 22581 near the socket 22582. A third spring 225852 is arranged on the side of the blocking block 22585 away from the socket 22582. A second pressing surface 225851 is arranged at the top end of the blocking block 22585 near the welding head 22584. A third pressing surface 225841 is arranged on the outer wall of the welding head 22584 near the second pressing surface 225851. The third pressing surface 225841 is slidably connected to the second pressing surface 225851.

[0056] By adopting the above technical solution, when the pressing block 22583 moves, the position corresponding to the notch 22572 on its outer wall (i.e., the first pressing surface 225831) will interact with the notch 22572. This design helps to limit the movement range of the pressing block 22583 and ensure its stability at a specific position. The blocking block 22585 is slidably connected inside the mounting rod 22581 near the socket 22582. This design allows the blocking block 22585 to move inside the mounting rod 22581 to fix or release the power cord. The third pressing surface 225841 is slidably connected to the second pressing surface 225851. This design enables the welding head 22584 to push the blocking block 22585 to move and release the fixation of the power cord when it drops by squeezing the second pressing surface 225851 through the third pressing surface 225841, so as to perform the welding operation.

[0057] The working principle and usage process of the embodiment of the present invention:

[0058] Before welding, it is necessary to adjust the position of the alignment module 225 in the fixing bracket 221 through the driving component 2211 according to the position of the solder joints, and adjust the position of the adjusting ring 22563 on the sleeve 22561 according to the distance between the solder joints. In the initial state, the adjusting rod 22564 is completely retracted into the sleeve 22561, and the clamping block 22565 is located at the end of the adjusting groove 22562. Since the clamping block 22565 extends outside the sleeve 22561 and its movement is restricted by the adjusting ring 22563, by rotating the position of the adjusting ring 22563 on the sleeve 22561, the length of the adjusting rod 22564 pulled out can be effectively controlled, thereby adjusting the distance between the docking components 2258, and after the docking components 2258 are separated, they can be accurately aligned with the solder joints on the circuit board.

[0059] After preparation, place the circuit board on the top of the fixing frame 211 and between the pushing plate 2132 and the clamping plate 21363. Just ensure that the direction of the solder joints on the circuit board is correct. Then, pull the connecting rod 2133 through the output end of the driving rod 212. The movement of the connecting rod 2133 will drive the pushing plate 2132 and the top plate 2135 to move linearly, making the pushing plate 2132 approach the clamping plate 21363. The surface of the top plate 2135 that docks with the docking bolt 21365 is inclined inward. During the movement of the top plate 2135, it will squeeze the two docking bolts 21365 through the inclined surface. After being squeezed, the two docking bolts 21365 will drive the movable rods 2136 to move towards each other. Due to the limitation of the mounting seat 2134, the movable rods 2136 can only move linearly and drive the clamping plate 21363 to move towards each other through the first spring 21364. During the movement of the pushing plate 2132 and the clamping plate 21363, the circuit board will be clamped in the middle. The pushing plate 2132 plays a pushing role, while the clamping plate 21363 plays a clamping role. At the same time, during the approach of the clamping plate 21363 to the circuit board, the circuit board will be lifted and separated from the fixing frame 211 through the top surface 21366, which can avoid the pins on the back of the circuit board causing the circuit board not to be placed horizontally, facilitating the subsequent welding process. If the clamping plate 21363 has completed the clamping of the circuit board, but the stroke of the pushing plate 2132 has not ended yet, the driving force of the top plate 2135 will act on the first spring 21364 to relieve the continuously increasing clamping force of the clamping plate 21363 by squeezing the first spring 21364.

[0060] Under normal circumstances, the pressing block 22583 is located inside the recess 22572. At this time, the blocking block 22585 is in close contact with the pressing block 22583, and the bottom end is blocked by the bottom of the socket 22582. After the circuit board is fixed, the power cord is inserted into the socket 22582. When the power cord is inserted into the socket 22582 to a certain depth, it will be blocked by the movable plate 222. This can prevent the welding end of the power cord from being inserted too much and misaligned with the welding point. When the power cord is inserted into place, the pushing component 223 is started, pushing the alignment module 225 to fall as a whole, gradually approaching the circuit board. Then, when the alignment module 225 is close to the circuit board, the output end of the second driving component 2251 pushes the push rod 2252 to fall. Because the second elastic member 22521 is relatively strong, the current pushing force cannot compress it, so the pressing plate 22522 and the driving plate 2253 fall together. The driving plate 2253 squeezes the connecting arm 2255 during the falling process, so that the connecting arm 2255 pushes the docking component 2258 to separate. During the separation of the docking component 2258, the pressing block 22583 is driven to move, so that the pressing block 225 83 is separated from the recess 22572, and during the separation process, it will be squeezed by the fixing rod 2257 to press the pressing surface 225831, so that the pressing block 22583 drops to a certain extent, and can clamp the power cord in the socket 22582, so that the power cord can be prevented from being detached or displaced during the separation of the docking component 2258. When the docking component 2258 stops moving after reaching the distance set by the adjustment component 2256, the end of the power cord has been aligned with the welding point, and the alignment module 225 has fallen to dock with the circuit board.

[0061] The second driving component 2251 continues to push, because the connecting arm 2255 cannot continue to unfold, the driving plate 2253 will not be able to move, and then the driving force of the second driving component 2251 will act on the second elastic member 22521 to compress it, and at the same time, the push rod 2252 continues to fall and drives the pressing plate 22522 to approach the docking component 2258, and the pressing plate 22522 falls to the top of the welding head 22584. When the welding head 22584 falls to the position close to the power line and the welding point, it will squeeze the pressing surface 225851 through the pressing surface 3 225841, prompting the stopper 22585 to start moving and separate from the pressing block 22583 and the socket 22582. Once the stopper 22585 is completely separated, the welding head 22584 continues to fall, and the power line and the welding point are heated and welded. At the same time, the welding head 22584 drives the pressing block 22583 to fall a short distance, and finally stays at the lowest point of the socket 22582.

[0062] After welding is completed, the first driving component 2211 pulls the alignment module 225 upward until the power cord moves out of the range of the socket 22582. Then, the second driving component 2251 moves upward to drive the components in the alignment module 225 to reset. At this time, the power cord after welding and the circuit board will fall above the fixing frame 211 and reset with the fixing mechanism 21. At this point, the welding of the circuit board and the power cord is completed.

[0063] In summary, compared with the prior art, the embodiments of the present invention have the following advantages:

[0064] Advantage 1: Efficient solder joint alignment. The first driving component 2211 can flexibly adjust the position of the alignment module 225 in the fixing frame 221 according to the solder joints. At the same time, the adjusting component 2256 can accurately adjust the distance between the docking components 2258 according to the solder joint spacing. For example, in the normal state, the adjusting rod 22564 is completely retracted into the sleeve 22561, and the block 22565 is at the end of the adjusting groove 22562. By rotating the position of the adjusting ring 22563 on the sleeve 22561, the length of the adjusting rod 22564 pulled out can be accurately limited, thereby realizing the precise alignment of the docking component 2258 and the solder joints of the circuit board, greatly improving the alignment efficiency, and solving the problem of difficult alignment in manual and semi-automatic methods.

[0065] Advantage 2: Reliable circuit board fixing. The design of the fixing mechanism 21 is very ingenious. Place the circuit board between the push plate 2132 and the clamping plate 21363 on the top of the fixing frame 211, and only ensure that the solder joints on the circuit board face the correct direction. The driving rod 212 pulls the connecting rod 2133 to drive the push plate 2132 and the top plate 2135 to move linearly. The top plate 2135 squeezes the docking bolt 21365 through the inclined surface, so that the movable rod 2136 drives the clamping plate 21363 to move towards each other, clamping the circuit board in the middle. At the same time, the clamping plate 21363 lifts the circuit board through the top surface 21366 to separate it from the fixing frame 211, avoiding the influence of the pins on the back of the circuit board on its horizontal placement, providing a stable and reliable fixing method for the subsequent welding process, and improving the stability and quality of welding.

[0066] Advantage 3: Precise power cord positioning and welding. After the circuit board is fixed, insert the power cord into socket 22582. The insertion depth is restricted by the movable plate 222 to prevent the welding end from being misaligned with the welding point. The pushing assembly 223 pushes the alignment module 225 downwards close to the circuit board. The driving assembly 2 2251 pushes the push rod 2252 downwards, causing the pressing plate 22522 and the driving plate 2253 to fall together, squeezing the connecting arm 2255 to push the docking assembly 2258 apart. At the same time, during the separation of the pressing block 22583 from the notch 22572, the pressing surface 225831 of the pressing block 22583 is squeezed by the fixing rod 2257 to clamp the power cord and prevent it from detaching or shifting. When the docking assembly 2258 reaches the distance set by the adjustment assembly 2256, the end of the power cord is precisely aligned with the welding point. Subsequently, the driving assembly 2 2251 continues to push, compressing the elastic member 2 22521, and the push rod 2252 drives the pressing plate 22522 to lower the welding head 22584 for welding. The entire process realizes the precise positioning and welding of the power cord, ensuring the stability of the welding quality and overcoming the problem of welding quality fluctuations caused by operational differences in manual welding.

[0067] Advantage 4: Convenient operation process and quick reset. The entire welding process is clear and coherent. From the adjustment of the alignment module 225 and the fixing of the circuit board in the preparation stage, to the positioning and welding of the power cord during the welding process, and then to the quick reset after welding is completed, such as the driving assembly 1 2211 pulling the alignment module 225 upwards and the driving assembly 2 2251 driving the components to reset, all greatly improve the production efficiency, reduce the operation time and labor intensity, and have significant advantages compared with traditional manual and semi-automatic welding methods.
