Figures 1-5 As shown, the system includes a first electric slide rail 1, a second electric slide rail 101, an electric slide rod 102, a welding head 2, a controller 5, and a base 6.

[0023] like Figures 1-5As shown, the feeding assembly includes a first conveyor belt 3, a first motor 4, a first roller 401, a connecting plate 601, and a sizing plate 602. The two connecting plates 601 are distributed front to back and are connected to the front and rear sides of the top of the base 6 by welding.

The first conveyor belt 3 is rotatably connected between the outside of the two first rollers 401. The two sizing plates 602 of different specifications are arranged front to back and are connected to the side of the two connecting plates 601 that are close to each other by welding. The side of the two sizing plates 602 that are close to each other is provided with a polyurethane pad to prevent the circuit board from being damaged during the sizing process.

[0024] like Figure 2 As shown, the clamping assembly includes an infrared sensor 7, a first bracket 8, a first electric push rod 9, a first spring 10, a guide rod 11, and a clamping plate 12. The infrared sensor 7 is bolted to the right side of the rear aligning plate 602. The first bracket 8 is welded to the front side of the front connecting plate 601, located slightly to the right of the center. The first electric push rod 9 is bolted to the inside of the first bracket 8 and passes through the front connecting plate 601. Both the infrared sensor 7 and the first electric push rod 9 are electrically connected to the controller 5. Two guide rods 11 are symmetrically distributed and slidably connected to the telescopic rod of the first electric push rod 9. The clamping plate 12 is connected to the rear end of the two guide rods 11 by welding and is located to the right of the front aligning plate 602 and in front of the rear aligning plate 602. The clamping surface of the clamping plate 12 is provided with a rubber pad, which increases the friction between the clamping plate and the circuit board and prevents the circuit board from being damaged during clamping. The first spring 10 is sleeved on the outside of the guide rod 11 and its two ends are fixedly connected to the clamping plate 12 and the telescopic rod of the first electric push rod 9, respectively.

[0025] like Figure 5 As shown, the feeding assembly includes a connecting frame 104, a second conveyor belt 31, a third motor 32, and a second roller 33. The connecting frame 104 is connected to the top right side of the base 6 by welding.

[0026] like Figures 3-5As shown, the loading assembly includes a baffle plate 13, a second electric push rod 14, a pinion 15, a large gear 16, a second motor 17, a second bracket 18, a pusher plate 19, a rotating rod 20, a material tray 21, and a material box 30. The second bracket 18 is welded to the right side of the rear connecting plate 601. The second electric push rod 14 is bolted to the inside of the second bracket 18. The pusher plate 19 is welded to the telescopic rod of the second electric push rod 14. The second motor 17 is bolted to the second bracket 18. Located below the second electric push rod 14, both the second electric push rod 14 and the second motor 17 are electrically connected to the controller 5. The large gear 16 is connected to the output shaft of the second motor 17 via a key connection. The rotating rod 20 is rotatably connected to the right side of the rear swing plate 602. The baffle plate 13 and the small gear 15 are both welded to the left end of the rotating rod 20. The baffle plate 13 is located to the left of the small gear 15. The small gear 15 and the large gear 16 mesh with each other, and the thickness of the small gear 15 is greater than that of the large gear 16. The position of the large gear 16 is... The center position of the pinion 15 ensures the stability and reliability of power transmission. The material tray 21 is welded to the right end of the rotating rod 20, and its lower part is embedded in the top of the base 6. This ensures that when the circuit board enters the material tray 21, it is restrained by the base 6. The material tray 21 has raised edges on both the front and rear sides to hold the circuit board in place and prevent it from slipping out. The pusher plate 19 is located to the left of the material tray 21, and its size is the same as the entrance width of the material tray 21, ensuring that the pusher plate 19 can accurately enter the material tray 21. The circuit board is pushed out. Silicone pads are provided on the upper, lower, front and rear sides of the pusher plate 19 to prevent direct contact between the pusher plate 19 and the material tray 21, reduce the wear of the material tray 21 by the pusher plate 19, and the silicone pads have a certain coefficient of friction, which can increase the friction between the pusher plate 19 and the material tray 21, making the pushing process more stable. The material box 30 is placed on the second conveyor belt 31. When the material tray 21 is rotated 90 degrees clockwise and stood upright, it can be aligned with the first material slot from the front of the material box 30, and can also be aligned with the pusher plate 19.

[0027] like Figure 5As shown, the pushing assembly includes a limiting sleeve 22, a movable rod 2201, a second spring 23, a limiting plate 24, a limiting roller 25, a rack 26, a full gear 27, a one-way gear 28, and a cross 29. The limiting sleeve 22 is welded to the right side of the rear connecting plate 601 and is located to the right of the second bracket 18. The movable rod 2201 is slidably connected inside the limiting sleeve 22. The limiting plate 24 is welded to the top of the movable rod 2201 and is located slightly to the right of the center. The limiting roller 25 is welded to the upper right side of the limiting sleeve 22. The movable rod 2201 slides outside the limiting roller 25. The second spring 23 is sleeved outside the limiting roller 25, and its two ends are respectively connected to the limiting plate 24 and the limiting sleeve 22. The rack 26 is fixedly connected to the right end of the movable rod 2201 by welding. The full gear 27 and the one-way gear 28 are both rotatably connected to the top right rear side of the base 6. The one-way gear 28 is located to the right of the full gear 27 and can mesh with the full gear 27 in one direction. The rack 26 meshes with the full gear 27. The rack 26, full gear 27 and one-way gear 28 have the same thickness, which allows them to work together better and reduces assembly problems or functional failures caused by thickness differences. The cross 29 is connected to the top center point of the one-way gear 28 by welding and is located to the left of the material box 30 and contacts it. The four corners of the cross 29 are all rounded to reduce the wear caused by sharp edges on the material box 30.

[0028] like Figures 1-4 As shown, the aligning plate 602, the clamping plate 12, and the baffle plate 13 are all in contact with the top surface of the first conveyor belt 3 to ensure the stability and accuracy of the circuit board during the conveying process.

[0029] Initially, the second spring 23 is in a compressed state. When this device is needed, the base 6 is placed between two production lines, so that the first conveyor belt 3 and the second conveyor belt 31 correspond to the two production lines respectively. Then, the control program is written into the controller 5. When the previous production line conveys the circuit board to be soldered to the left side of the first telescopic belt, the controller 5 starts the first motor 4 and the infrared sensor 7. The output shaft of the first motor 4 drives the left first roller 401 to rotate, so that it works in coordination with the right first roller 401, pulling the first conveyor belt 3 to rotate and convey the circuit board to be soldered to the right. During the conveying process, the circuit board contacts the aligning plate 602 and moves forward or backward along its edge to ensure that the circuit board remains in the center position. When the circuit board is conveyed to the soldering... When the contact plate 13 is temporarily blocked below the connector 2, the infrared sensor 7 detects the circuit board and transmits a signal to the controller 5. The controller 5 responds quickly, controlling the extension rod of the first electric push rod 9 to extend, driving the guide rod 11 to move backward, so that the clamping plate 12 cooperates with the rear aligning plate 602 to clamp the circuit board. During clamping, the clamping plate 12 is pressed forward by the circuit board, and the first spring 10 is compressed accordingly, applying a forward pressure to the clamping plate 12 to ensure that the circuit board is firmly clamped. At the same time, the controller 5 controls the operation of the first electric slide rail 1 and the second electric slide rail 101, so that the second electric slide rail 101 moves left and right according to a preset path, and the electric slide rod 102 moves up and down according to a preset path, thereby aligning and contacting the welding head 2 with the circuit. After the solder joints on the board are aligned and in contact, the welding head 2 starts welding. During the welding process, the second electric slide rail 101 and the electric slide rod 102 move as needed, allowing the welding head 2 to weld solder joints at different positions on the circuit board. After welding is completed, the welding head 2 stops running, and the second electric slide rail 101 and the electric slide rod 102 move back to their original positions. Then, the first electric push rod 9 is activated, controlling its telescopic rod to retract, driving the guide rod 11 to move forward to its original position, causing the clamping plate 12 to release the circuit board. The first spring 10 then returns to its original state, causing the clamping plate 12 to move backward to its original position. Next, the second motor 17 is activated, causing its output shaft to drive the large gear 16 to rotate clockwise. The large gear 16 meshes with the small gear 15 in the forward direction, and the small gear 15 drives the rotating rod 20 to rotate clockwise. At 90 degrees, the rotating rod 20 simultaneously drives the baffle plate 13 to rotate 90 degrees clockwise, so that the baffle plate 13 no longer obstructs the circuit board. At this time, the second conveyor belt 31 continues to rotate and transport the circuit board to the right. When the circuit board is off-center from the baffle plate 13, the output shaft of the second motor 17 is immediately reversed, driving the large gear 16 to rotate counterclockwise. The large gear 16 meshes with the small gear 15 in the opposite direction, and the small gear 15 drives the rotating rod 20 to rotate 90 degrees counterclockwise. The circuit board is continued to be transported to the right and enters the material tray 21. Then, the output shaft of the second motor 17 is controlled to rotate clockwise, so that the rotating rod 20 drives the material tray 21 to rotate 90 degrees clockwise. The second electric push rod 14 is activated, controlling its telescopic rod to extend and drive the pusher plate 19 to move to the right and enter the material tray 21.The internal circuit board is pushed into the first material slot of the material box 30. During this process, the pusher plate 19 no longer presses against the movable rod 2201, and the second spring 23 returns to its original state, causing the movable rod 2201 to drive the rack 26 to move to the right, so that the rack 26 engages with the full gear 27 in the forward direction. The full gear 27 rotates 90 degrees counterclockwise and does not engage with the one-way gear 28. After the push is completed, the telescopic rod of the second electric push rod 14 retracts, driving the pusher plate 19 to move to the left and exit from the material tray 21. During this process, the pusher plate 19 presses against the movable rod 2201 to move to the left and reset. The second spring 23 is compressed, and the movable rod 2201 simultaneously drives the rack 26 to move to the left, causing the rack 26 to mesh with the full gear 27 in the opposite direction. The full gear 27 rotates 90 degrees clockwise and meshes with the one-way gear 28 in one direction. The one-way gear 28 then drives the cross 29 to rotate 90 degrees clockwise, pushing the material box 30 forward a suitable distance so that the second material slot of the material box 30 is aligned with the material tray 21. Finally, the output shaft of the second motor 17 is reversed, causing the rotating rod 20 to drive the material tray 21 to rotate 90 degrees counterclockwise to reset. Repeat the above steps to continue soldering the next circuit board.

[0030] It is worth noting that when the material box 30 is full, the third motor 32 is started, and its output shaft drives the front second roller 33 to rotate, so that it works in coordination with the rear second roller 33 to pull the second conveyor belt 31 to rotate and transport the material box 30 backward, so that the material box 30 enters the next production line. After entering, the third motor 32 is turned off and a new material box 30 is placed on the second conveyor belt 31.

[0031] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
