Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a power adapter welding device. Background Technology

[0002] A power adapter is a device that converts alternating current (AC) supplied by mains power into low-voltage direct current (DC) suitable for electronic devices. Widely used in various portable and stationary electronic devices, it provides stable power to mobile devices such as laptops, smartphones, tablets, and wireless routers. It is also commonly used in digital cameras, game consoles, smart home devices, and other electronic products requiring external power. Through precise voltage and current conversion, the power adapter ensures the safe and efficient operation of these devices while protecting internal circuitry from power fluctuations. Existing soldering processes specifically target typical soldering locations in the power adapter manufacturing process, including but not limited to: ultrasonic sealing welding of the joint between the upper and lower plastic shells of the adapter to achieve robust enclosure; and soldering of component leads on the internal circuit board (PCB) of the adapter. These soldering locations are standard and necessary connection points in the power adapter product structure.

[0003] Currently, most factories still rely on manual operation in the soldering process of power adapters. This method is not only time-consuming and labor-intensive, but also makes it difficult to guarantee the consistency and precision of soldering due to differences in worker skill levels, which can easily lead to unstable product quality. In addition, manual operation increases the risk of human error, further affecting production efficiency and yield. More importantly, manual intervention is still required during the soldering process to control the movement of the soldering head to ensure the accuracy and consistency of the soldering path. This not only increases the workload of operators, but also limits the overall automation level of the production line, affecting the continuity and efficiency of production.

[0004] Therefore, it is necessary to design a power adapter soldering device to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of most factories still relying on manual operation for welding power adapters, which leads to time-consuming, labor-intensive, unstable quality, increased error risk, and the need for manual control of the welding head movement, increasing the workload and limiting automation and efficiency, the technical problem of this utility model is to provide a power adapter welding device.

[0006] The technical implementation scheme of this utility model is as follows: A power adapter welding device includes a welding table, a first electric slide rail, a connecting rod, a second electric slide rail, an ultrasonic welding head, a first motor, a rotating shaft, a first push rod, a limiting rod, a placement frame, a second push rod, a connecting column, a spring, a baffle, a conveyor belt, and a controller. The welding table has two first electric slide rails symmetrically fixedly connected to its top rear side. Connecting rods are slidably connected to both first electric slide rails. A second electric slide rail is fixedly connected between the front parts of the two connecting rods. An ultrasonic welding head is slidably connected to the second electric slide rail. A first motor is installed inside the left side of the welding table. The output shaft of the first motor extends out of the welding table and is connected to a rotating shaft. A first push rod is slidably connected to the rotating shaft. A limiting rod is slidably connected to the middle of the first push rod. A slot is provided in the middle, and a limiting rod is fixedly connected to the welding table. A placement frame is installed on the top of the welding table behind the first push rod. A second push rod is slidably connected to the rear of the placement frame. Connecting posts are fixedly connected to both sides of the second push rod, and connecting posts are also fixedly connected to both sides of the front of the placement frame. Springs are connected between the symmetrical connecting posts on both sides of the placement frame and the second push rod. A baffle is fixedly connected to the top of the welding table in front of the placement frame, and the first push rod is located behind the baffle. A conveyor belt is installed on the right side of the top of the welding table, and the conveyor belt is located below the ultrasonic welding head. The first push rod is located to the left of the conveyor belt. A controller is fixedly connected to the right side of the front of the welding table. The first electric slide rail, the second electric slide rail, the ultrasonic welding head, the first motor, and the conveyor belt are all electrically connected to the controller.

[0007] Optionally, the conveyor belt is made of silicone material that is resistant to high temperatures and wear.

[0008] Optionally, multiple elongated holes are evenly spaced on both sides of the welding table.

[0009] Optionally, it also includes a sensor, which is installed on the bottom left side of the ultrasonic welding head.

[0010] Optionally, it also includes a door panel, a sliding plate, and a loading box. The door panel is rotatably connected to the front of the welding table. A sliding plate is installed inside the right side of the welding table, with one end of the sliding plate located below the right side of the conveyor belt. A loading box is placed inside the welding table, with the other end of the sliding plate aligned with the inside of the loading box.

[0011] Optionally, the slide plate is tilted at 45 degrees and a handle is installed at the front center of the loading box.

[0012] Optionally, it also includes fans and screens, with fans installed on both sides of the left side of the loading box and screens installed on both sides of the two fans.

[0013] Optionally, it also includes a second motor, bevel gears, screws, and clamping plates. The second motor is installed on the front top of the welding table. Bevel gears are connected to both sides of the output shaft of the second motor. Two screws are rotatably connected to the front top of the welding table. Bevel gears are also fixedly connected to the front ends of the two screws. The bevel gears on the screws mesh with the bevel gears on the corresponding output shafts of the second motor. A clamping plate is threaded between the two screws. The clamping plate is located in front of the conveyor belt. The second motor is electrically connected to the controller.

[0014] Optionally, it also includes an air inlet pipe, a telescopic pipe, an air pump, and an air filling box. The air inlet pipe is connected to and communicates with the front right side of the middle part of the ultrasonic welding head. Air inlets are opened at the top and bottom of the ultrasonic welding head, and the air inlets are connected to the air inlet pipe. The upper air inlet is connected to and communicates with the telescopic pipe. The other end of the telescopic pipe is connected to and communicates with the air pump. An air filling box is installed on the top right side of the second electric slide rail. The air filling box is located on the right side of the ultrasonic welding head, and the air pump is located inside the air filling box. The air pump is electrically connected to the controller.

[0015] Optionally, the telescopic tube is made of a flexible material.

[0016] Optionally, it also includes an activated carbon filter screen, and multiple air outlets are evenly spaced at the rear of the air box, with an activated carbon filter screen installed on each air outlet.

[0017] This utility model has the following advantages: 1. By placing the power adapter into the placement frame, the second push rod contacts and fixes it, pushes the second push rod and the connecting column to move backward and stretches the spring. When the placement frame is full of power adapters, the addition of new power adapters is stopped, the first motor is started, and the first push rod moves linearly left and right through the rotating shaft, pushing the power adapter towards the conveyor belt. After each push, the spring releases energy, causing the second push rod and the connecting column to move forward and reset until the power adapter is blocked by the baffle. This transportation work does not require manual operation, reduces the workload of operators, and improves the continuity and efficiency of production.

[0018] 2. This utility model uses a controller to start the first electric slide rail, which drives the connecting rod and the ultrasonic welding head on the second electric slide rail to move up and down. Because the sensor at the bottom of the welding head detects the position of the power adapter, it automatically adjusts the height and horizontal position to ensure accurate welding. When lateral movement is required, the controller starts the second electric slide rail. The conveyor belt is made of high temperature resistant and wear-resistant silicone material to ensure long-term stability and flexibility.

[0019] 3. In this utility model, the welded power adapter slides from the slide plate into the loading box. The welding table has ventilation holes on both sides. When working with the fan, it can draw in external air and enter the loading box through the ventilation holes, thereby effectively dissipating heat from the welded power adapter. Because the front of the fan is equipped with a mesh screen, it prevents dust from entering the loading box through the fan and avoids contaminating the product.

[0020] 4. This utility model starts the second motor through the controller. The output shaft of the second motor drives the bevel gear to rotate, which in turn drives the screw to rotate, causing the clamping plate to move backward (i.e. towards the power adapter). When the clamping plate contacts the power adapter, the clamping plate pushes the power adapter backward and clamps it on the conveyor belt, thereby firmly clamping the power adapter and preventing it from shifting or vibrating during the welding process, thus ensuring welding accuracy.

[0021] 5. This utility model starts the air pump through the controller, and harmful gases will enter the air inlet pipe through the air inlet hole in sequence, and then be guided into the air box through the telescopic tube. After being adsorbed by the activated carbon filter, clean air will be discharged from the air outlet hole, which effectively reduces environmental pollution and provides a fresh and environmentally friendly working environment. Since the telescopic tube is made of soft material, it can be freely stretched or contracted when the ultrasonic welding head moves left and right, without interfering with the welding operation, thereby improving production efficiency.

Detailed Implementation

It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0036] Example 1: A power adapter welding device, such as Figures 1-9 , Figure 11 and Figure 12As shown, the assembly includes a welding table 1, a first electric slide rail 2, a connecting rod 201, a second electric slide rail 3, an ultrasonic welding head 4, a sensor 41, a first motor 5, a rotating shaft 6, a first push rod 7, a limiting rod 8, a placement frame 9, a second push rod 10, a connecting column 11, a spring 12, a baffle 13, a conveyor belt 14, a controller 15, a door panel 16, a sliding plate 17, a loading box 18, a fan 19, and a mesh screen 191. The welding table 1 has two first electric slide rails 2 symmetrically mounted on its top rear side using screws. Multiple elongated holes are evenly spaced on both sides of the welding table 1. Connecting rods 201 are slidably connected to both first electric slide rails 2. A second electric slide rail 3 is welded to the front of the 201 unit. An ultrasonic welding head 4 is slidably connected to the second electric slide rail 3. A sensor 41 is installed on the bottom left side of the ultrasonic welding head 4. A first motor 5 is installed inside the left side of the welding table 1. The output shaft of the first motor 5 passes through the welding table 1 and is connected to a rotating shaft 6. A first push rod 7 is slidably connected to the rotating shaft 6. A limit rod 8 is slidably connected to the middle of the first push rod 7, and a groove is opened in the middle of the first push rod 7. The limit rod 8 is welded to the welding table 1. A placement frame 9 is installed on the top of the welding table 1 behind the first push rod 7. A second push rod 10 is slidably connected to the rear of the placement frame 9. Connecting posts 11 are welded to both the left and right sides, and connecting posts 11 are also welded to the left and right sides of the front of the placement frame 9. Springs 12 are connected between the symmetrical connecting posts 11 on the left and right sides of the placement frame 9 and the second push rod 10. A baffle 13 is welded to the top of the welding table 1 in front of the placement frame 9, and the first push rod 7 is located behind the baffle 13. A conveyor belt 14 is installed on the right side of the top of the welding table 1. The conveyor belt 14 is made of high-temperature resistant and wear-resistant silicone material. The conveyor belt 14 is located directly below the ultrasonic welding head 4. The first push rod 7 is located directly to the left of the conveyor belt 14. The front right side of the welding table 1 is connected by screws. The welding table 1 is equipped with a controller 15. The first electric slide rail 2, the second electric slide rail 3, the ultrasonic welding head 4, the sensor 41, the first motor 5, and the conveyor belt 14 are all electrically connected to the controller 15. The welding table 1 is rotatably connected to the front middle of the door panel 1. The welding table 1 has a sliding plate 17 installed inside the right side of the welding table 1. The sliding plate 17 is tilted at 45 degrees and one end of the sliding plate 17 is located below the right side of the conveyor belt 14. The welding table 1 has a loading box 18 inside. The loading box 18 has a handle installed in the front middle of the loading box 18. The other end of the sliding plate 17 is aligned with the inside of the loading box 18. Fans 19 are installed on the front and rear sides of the left side of the loading box 18. The two fans 19 have mesh screens 191 installed on the left and right sides of the two fans 19.

[0037] When using this device, operators should first wear appropriate earplugs and gloves for safety. Then, place the power adapter into the placement box 9. At this point, the second push rod 10 will contact and secure the power adapter. As the power adapter is inserted, it pushes the second push rod 10 and the connecting post 11 backward, simultaneously stretching the spring 12. When the placement box 9 is full of power adapters, stop adding new power adapters. Next, the controller 15 starts the first motor 5, whose output shaft drives the rotating shaft 6 to rotate, thereby causing the first push rod 7 to move left and right. Due to the presence of the limit rod 8, The first push rod 7 can only move in a straight line, thus ensuring accurate pushing of the power adapter onto the conveyor belt 14. Each time the first push rod 7 pushes a power adapter onto the conveyor belt 14, the spring 12 releases its stored energy, pushing the second push rod 10 and the connecting post 11 forward to their initial positions until the power adapter is blocked by the baffle 13. Once the power adapter is on the conveyor belt 14, the controller 15 activates the first electric slide rail 2, which drives the connecting rod 201 and the ultrasonic welding head 4 mounted on the second electric slide rail 3 to move up and down. Because the ultrasonic welding head 4 is equipped with a sensor 41 at its bottom, it can... The position of the power adapter on the conveyor belt 14 is detected, and it is automatically adjusted to the appropriate height and level to ensure precise welding. If the ultrasonic welding head 4 needs to be moved laterally, it can be achieved by activating the second electric slide rail 3 via the controller 15. Because the conveyor belt 14 is made of high-temperature resistant and wear-resistant silicone material, it ensures long-term stability and flexibility. After welding, the power adapter continues to move along the conveyor belt 14 and finally falls onto the 45-degree inclined slide plate 17, sliding into the loading box 18. To help cool the welded power adapter, elongated holes are provided on both sides of the welding table 1. When fan 19 operates, it draws in outside air into the material box 18. The front of fan 19 is also equipped with a mesh screen 191 to prevent dust from entering the material box 18 and contaminating the product. After the heat dissipation process is completed, fan 19 is turned off. After welding is completed, the operator can turn off the first motor 5, the first electric slide rail 2, the second electric slide rail 3 and the conveyor belt 14 through controller 15. Finally, the operator opens the door panel 16, pulls the handle, removes the material box 18 from the welding table 1, takes out the welded power adapter, and puts the material box 18 back in its original position and closes the door panel 16. If welding is required again, the above operation can be repeated.

[0038] like Figure 1 , Figure 4 and Figures 7-12As shown, it also includes a second motor 20, bevel gears 21, screws 22, clamping plates 23, an air inlet pipe 24, a telescopic pipe 25, an air pump 26, an air tank 27, and an activated carbon filter 28. The second motor 20 is mounted on the front top of the welding table 1. Bevel gears 21 are connected to both sides of the output shaft of the second motor 20. Two screws 22 are rotatably connected to the front top of the welding table 1. Bevel gears 21 are also fixedly connected to the front ends of the two screws 22. The bevel gears 21 on the screws 22 mesh with the corresponding bevel gears 21 on the output shaft of the second motor 20. A clamping plate 23 is threaded between the two screws 22. The clamping plate 23 is located in front of the conveyor belt 14. The machine 20 is electrically connected to the controller 15. The front right side of the middle of the welding head is connected to and connected to the air inlet pipe 24. The upper and lower parts of the ultrasonic welding head 4 are provided with air inlet holes 251, which are connected to the air inlet pipe 24. The upper air inlet hole 251 is connected to and connected to the telescopic pipe 25. The telescopic pipe 25 is made of soft material. The other end of the telescopic pipe 25 is connected to and connected to the air pump 26. The top right side of the second electric slide rail 3 is equipped with an air box 27. The air box 27 is located on the right side of the ultrasonic welding head 4, and the air pump 26 is located inside the air box 27. Multiple air outlet holes 271 are evenly spaced at the rear of the air box 27. Each air outlet hole 271 is equipped with an activated carbon filter screen 28.

[0039] When clamping and welding of the power adapter on conveyor belt 14 is required, the operator can start the second motor 20 via controller 15. The output shaft of the second motor 20 drives the bevel gear 21 to rotate, which in turn drives the screw 22 to rotate, causing the clamping plate 23 to move backward (i.e., towards the power adapter). When the clamping plate 23 contacts the power adapter, it pushes the power adapter backward and clamps it onto the conveyor belt 14, thus firmly clamping the power adapter and preventing displacement or vibration during welding, ensuring welding accuracy. After welding is completed, the clamping plate 23 moves forward, releasing the power adapter so that it can continue to be transported with the conveyor belt 14. This process is repeated to process subsequent power adapters in sequence. If clamping is no longer required, the operator... The operator can turn off the second motor 20 through the controller 15. During the ultrasonic welding process, some harmful gases may be generated. To deal with this problem, the operator can start the air pump 26 through the controller 15. The harmful gases will enter the air inlet pipe 24 through the air inlet 251, and then be guided into the air box 27 through the telescopic tube 25. Finally, the clean air after being adsorbed by the activated carbon filter 28 will be discharged from the air outlet 271, reducing environmental pollution and providing a fresher and more environmentally friendly working environment. Since the telescopic tube 25 is made of soft material, it can be freely stretched or contracted when the ultrasonic welding head 4 moves left and right without interfering with the welding operation, thereby improving production efficiency. After the welding is completed, the operator can turn off the air pump 26 through the controller 15.

[0040] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
