In the entire production process, the welding link of the power cord and the circuit board is particularly critical, and the welding quality directly determines the electrical performance and safety of the product.

[0003] Among the rich and varied power adapter products, there is a small type of power adapter with a special circuit board design. This type of circuit board is only provided with two welding points for connecting the power cord, and the two welding points are arranged in a straight line and distributed symmetrically near the center of the circuit board.

[0004] At present, many small production enterprises mainly adopt manual welding or semi-automatic welding when welding the power cord for this special circuit board. In the manual welding process, due to the particularity of the welding point position, the operator must spend a lot of time to accurately align the welding point. This operation is not only tedious, but also greatly slows down the production progress, resulting in extremely low overall production efficiency. Moreover, the quality of manual welding is seriously dependent on the technical level, work experience and fatigue state of the welder, and there are obvious differences in the control of welding temperature, welding time and soldering amount among different operators, which makes the welding quality fluctuate greatly and it is difficult to guarantee stable product quality.

[0019] The application has the following beneficial effects:

[0020] 1. Efficient circuit board clamping and positioning, through the cooperative work of the fixed frame, the driving rod, the clamping assembly and the like, only the circuit board welding point is placed on the top of the fixed frame in the correct direction, the driving rod pulls the connecting rod, drives the push plate and the top plate to move, the top plate extrudes the butt joint bolt through the inclined surface, the movable rod drives the clamping plate to relatively move, the circuit board can be quickly clamped and lifted in the middle, the placement is not horizontal due to the pins on the back of the circuit board, the whole process is simple and efficient to operate, greatly saves the positioning time of the circuit board, and improves the production efficiency.

[0021] 2. Precise power cord docking and welding: The docking mechanism's fixed frame, movable plate, pusher assembly, and alignment module work together. Before welding, the drive assembly adjusts the alignment module's position based on the weld point location and spacing, while the adjustment assembly precisely controls the spacing between the docking components. When the power cord is plugged into the socket, the pusher assembly lowers the alignment module, which then drives the connecting arm to separate the docking components while simultaneously clamping the power cord, ensuring precise alignment of the cord ends with the weld point. The welding head then descends to complete the weld. The entire process achieves highly precise docking and welding between the power cord and the weld point, ensuring weld quality.

[0022] 3. To adapt to different solder joint layouts, the sleeve, adjusting ring, adjusting rod and block of the adjustment component are cleverly designed. By rotating the position of the adjusting ring on the sleeve, the length of the adjusting rod that can be pulled out can be limited, thereby flexibly controlling the spacing between the docking components. It can quickly adapt to the different distances between two solder points on different small power adapter circuit boards, enhancing the versatility and applicability of the welding system.

[0023] 4. Protect welding components and stabilize the welding process. During the circuit board clamping process, if the clamping plate completes clamping but the push plate has not yet completed its travel, the pushing force of the top plate will act on the spring, preventing the clamping plate from continuously increasing its clamping force and preventing damage to the circuit board. During the welding process, the elastic member, pressure block, and stopper cooperate with each other. For example, when the welding head falls, the pressure surface squeezes the stopper to separate it, ensuring smooth welding. At the same time, it can stabilize and protect the power line during the welding process, further improving the welding quality and equipment reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] By adopting the technical scheme, the mounting rod 22581 is in sliding connection with the bottom of the fixing rod 2257, and the bottom end thereof is hinged with the connecting arm 2255, so that the docking assembly 2258 can be separated or approached under the pushing of the connecting arm 2255. Before welding, the position of the adjusting ring 22563 on the sleeve 22561 is adjusted through rotation, so as to limit the length of the adjusting rod 22564 pulled out, and then the spacing between the two mounting rods 22581 (that is, the docking assembly 2258) is controlled, so as to ensure that they can be accurately aligned with the welding points on the circuit board.

[0057] The working principle and use process of the embodiment of the application are as follows:

[0058] Before welding, the position of the alignment module 225 in the fixed frame 221 is adjusted by the driving assembly 2211 according to the position of the welding spot, and the position of the adjusting ring 22563 on the sleeve 22561 is adjusted according to the distance between the welding spots. In the initial state, the adjusting rod 22564 is completely accommodated in the sleeve 22561, and the clamping block 22565 is located at the end of the adjusting groove 22562. Since the clamping block 22565 extends to the outside of the sleeve 22561, its movement is limited by the adjusting ring 22563. Therefore, 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, and the distance between the butt joint assemblies 2258 is adjusted. After the butt joint assemblies 2258 are separated, they can be accurately aligned with the welding points of the circuit board.

[0059] After preparation, the circuit board is placed on the top of the fixed frame 211 between the push plate 2132 and the clamping plate 21363, and only the direction of the welding points on the circuit board needs to be kept correct. Then the connecting rod 2133 is pulled by the output end of the driving rod 212. The movement of the connecting rod 2133 drives the linear movement of the push plate 2132 and the top plate 2135, so that the push plate 2132 moves towards the clamping plate 21363. The surface of the top plate 2135 that is in butt joint with the butt joint bolt 21365 is inclined inward. During the movement of the top plate 2135, the two butt joint bolts 21365 are pressed by the inclined surface, and the two butt joint bolts 21365 are pressed to drive the movable rod 2136 to move relatively. Due to the limitation of the mounting seat two 2134, the movable rod 2136 can only move linearly and drive the clamping plate 21363 to move relatively through the spring one 21364. During the movement of the push plate 2132 and the clamping plate 21363, the circuit board is clamped in the middle. The push plate 2132 plays a pushing role, and the clamping plate 21363 plays a clamping role. At the same time, during the movement of the clamping plate 21363 towards the circuit board, the circuit board is lifted by the top surface 21366 and separated from the fixed frame 211. In this way, the pins on the back of the circuit board can be avoided to cause the circuit board to be placed horizontally, which is beneficial to the subsequent welding process. If the clamping plate 21363 has completed clamping of the circuit board, but the stroke of the push plate 2132 has not been completed, the pushing force of the top plate 2135 will act on the spring one 21364 to relieve the clamping force of the clamping plate 21363.

[0060] In normal circumstances, the pressure block 22583 is located inside the notch 22572, at this time the stop block 22585 is in close contact with the pressure block 22583, and the bottom end is blocked at 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 soldering end of the power cord from being inserted too much and misaligned with the welding point. After the power cord is inserted into place, the push assembly 223 is activated, pushing the alignment module 225 as a whole to fall and gradually approach the circuit board. Then, when the alignment module 225 is about to approach the circuit board, the output end of the drive assembly two 2251 pushes the push rod 2252 to fall. Because the strength of the elastic member two 22521 is relatively large, the current pushing force cannot compress it, so the pressure plate 22522 and the drive plate 2253 will fall together. The drive plate 2253 will squeeze the connecting arm 2255 during the falling process, thereby causing the connecting arm 2255 to push the docking assembly 2258 to separate. In the process of separating the docking assembly 2258, the pressure block 22583 will be moved, causing the pressure block 22583 to separate from the notch 22572. In the process of separation, it will be squeezed by the fixed rod 2257 against the pressure surface one 225831, thereby causing the pressure block 22583 to fall to a certain extent and clamp the power cord in the socket 22582. This can prevent the power cord from coming off or shifting during the separation of the docking assembly 2258. After the docking assembly 2258 moves to the distance set by the adjustment assembly 2256, it stops moving. At this time, the end of the power cord has been aligned with the welding point, and the alignment module 225 has fallen to the docking position of the circuit board.

[0061] The drive assembly two 2251 continues to push. Because the connecting arm 2255 cannot continue to expand, the drive plate 2253 will not move. Then the pushing force of the drive assembly two 2251 will act on the elastic member two 22521 to compress it, and the push rod 2252 will continue to fall, causing the pressure plate 22522 to approach the docking assembly 2258. The pressure plate 22522 falls to the top of the welding head 22584. When the welding head 22584 falls close to the position of the power cord and the welding point, it will squeeze the pressure surface two 225851 through the pressure surface three 225841, causing the stop block 22585 to start moving and separating from the pressure block 22583 and the socket 22582. Once the stop block 22585 is completely separated, the welding head 22584 continues to fall and welds the power cord and the welding point. At the same time, the welding head 22584 causes the pressure block 22583 to fall a small distance and finally stop at the lowest point of the socket 22582.

[0062] When the welding is completed, the driving assembly one 2211 pulls the alignment module 225 to move up, and moves up to the range of the power cord disengaging socket 22582, and then the driving assembly two 2251 moves up to reset the components in the alignment module 225, at this time the power cord after welding and the circuit board will fall above the fixed frame 211 with the fixed mechanism 21 reset, at this time the welding of the circuit board and the power cord is completed.

[0063] In summary, compared with the prior art, the embodiment of the application has the following advantages:

[0064] Advantage one, efficient welding point alignment, the driving assembly one 2211 can flexibly adjust the position of the alignment module 225 in the fixed frame 221 according to the welding point, and the adjustment assembly 2256 can accurately adjust the distance between the docking assemblies 2258 according to the distance between the welding points. For example, in the normal state, the adjusting rod 22564 is completely retracted into the sleeve 22561, the clamping block 22565 is at the end of the adjusting groove 22562, and the position of the adjusting ring 22563 on the sleeve 22561 can be rotated to accurately limit the length of the adjusting rod 22564 pulled out, thereby realizing accurate alignment of the docking assemblies 2258 and the welding points of the circuit board, greatly improving the alignment efficiency and solving the problem of difficult alignment in manual and semi-automatic methods.

[0065] Advantage two, reliable circuit board fixation, the fixed mechanism 21 is designed very ingeniously, the circuit board is placed between the push plate 2132 and the clamping plate 21363 on the top of the fixed frame 211, and only the welding points on the circuit board need to be oriented correctly. 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 is pressed against the docking bolt 21365 through the inclined surface, the movable rod 2136 drives the clamping plate 21363 to move relatively, and the circuit board is clamped in the middle. At the same time, the clamping plate 21363 lifts the circuit board through the top surface 21366 to separate the circuit board from the fixed frame 211, avoiding the influence of the pins on the back of the circuit board on its horizontal placement, providing a stable and reliable fixation method for the subsequent welding process, and improving the stability and quality of welding.

[0066] The third advantage is accurate power line positioning and welding. After the circuit board is fixed, the power line is inserted into the socket 22582, and the insertion depth is limited 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 to fall close to the circuit board, the driving assembly two 2251 pushes the pushing rod 2252 to fall, the pressing plate 22522 and the driving plate 2253 fall together, the connecting arm 2255 is squeezed to push the docking assembly 2258 to separate, and the pressing block 22583 is squeezed against the pressing surface one 225831 by the fixed rod 2257 during the separation from the notch 22572 to clamp the power line to prevent it from being separated or displaced. When the docking assembly 2258 reaches the set distance of the adjusting assembly 2256, the end of the power line is accurately aligned with the welding point, and then the driving assembly two 2251 continues to push, the elastic member two 22521 is compressed, the pushing rod 2252 drives the pressing plate 22522 to make the welding head 22584 fall and weld. The whole process realizes accurate positioning and welding of the power line, ensures the stability of the welding quality, and overcomes the problem of welding quality fluctuation caused by operation difference in manual welding.

[0067] The fourth advantage is convenient operation process and quick reset. The whole welding process is clear and coherent, from the adjustment of the alignment module 225 in the preparation stage, the fixing of the circuit board, to the positioning and welding of the power line in the welding process, and then to the quick reset after the welding is completed, such as pulling the alignment module 225 up by the driving assembly one 2211 and resetting the components by the driving assembly two 2251. This greatly improves the production efficiency, reduces the operation time and labor intensity, and has significant advantages compared with traditional manual and semi-automatic welding methods.
