Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and specifically, it is a circuit board welding device with precise positioning. Background Art

[0002] Many complex electronic devices often require multiple functions to work together. A single circuit board may only be able to achieve partial functions. By welding two circuit boards together, different functional circuit modules can be combined to achieve more powerful and complex functions. Welding a new circuit board can add new functions or improve performance to the original system. For example, in some industrial control devices, by welding an expansion circuit board, new sensor interfaces or communication protocol supports can be added, enabling the device to adapt to new production requirements or communicate compatibly with other advanced devices. Drag soldering refers to a soldering method in which the soldering iron tip is dragged along the parts to be soldered (such as pins, circuits, etc.) during the soldering process, so that the solder melts and adheres to the soldering parts during the dragging process, thereby achieving connection. When soldering solder joints with small spacing, close and uniform arrangement, such as the pins of an integrated circuit chip, drag soldering can complete the soldering of multiple solder joints at one time, saving time and improving efficiency.

[0003] A Chinese patent with the publication number CN118237689A proposes a circuit board welding device, including a workbench. A placement table is arranged at the center of the top of the workbench. First cylinders are respectively slidably connected to both ends of the workbench where the placement table is located. A first motor is arranged at the output end of the first cylinder. An installation plate is arranged at the output end of the first motor. U-shaped frames are respectively slidably connected to both ends of the installation plate where the first motor is located. A stopper is arranged at the bottom of the U-shaped frame. A first electric telescopic rod is arranged at the top of the U-shaped frame. A pressing block is arranged at the output end of the first electric telescopic rod.

The downward movement of the V-shaped support frame by a preset distance drives the L-shaped sliding plate to move downward by a preset distance. The L-shaped sliding plate is restricted by a plurality of rollers on the special-shaped bracket, and the L-shaped sliding plate moves towards the central axis direction of the V-shaped support frame. The circuit board is fed into the middle side of the V-shaped support frame through the flipping loading device, and the spring is compressed.

[0020] 2. The output end of the third cylinder moves upward, driving the C-shaped plate to move upward. The upward movement of the C-shaped plate removes the blockage of the circuit board. At this time, the circuit board can move downward along the second belt conveyor normally. When the circuit board is conveyed to the multi-station clamping device by the second belt conveyor, the output end of the third cylinder locks short, and then the output end of the third cylinder extends to drive the C-shaped plate to move downward. The inclined surface at one end of the C-shaped plate contacts the circuit board on the multi-station clamping device, and pushes the circuit board to the standard position of the multi-station clamping device. At this time, the front and rear positions of the circuit board are quickly aligned, which is beneficial to the quick clamping of the front and rear positions of the circuit board while continuously loading the circuit board;

[0021] 3. The sliding bracket moves downward, driving the arc-shaped electric slide rail and the automatic soldering gun to move downward. The automatic soldering gun cooperates with the first linear module and the inclined clamping mechanism to realize the drag soldering of two circuit boards. The output end of the arc-shaped electric slide rail moves back and forth to drive the automatic soldering gun to move back and forth to adjust the angle of the automatic soldering gun, so as to avoid the overly prominent electronic components on the circuit board. By presetting the back-and-forth movement of the output end of the arc-shaped electric slide rail to avoid the overly prominent electronic components on the circuit board, it is beneficial to continuously avoid the overly prominent electronic components on the circuit board during drag soldering.

The multi-station clamping device 3 includes: a first linear module 31 and an inclined clamping mechanism. The first linear module 31 is fixedly installed in the middle side of the bottom plate 1. The two inclined clamping mechanisms are respectively fixedly installed on the left and right sides of the output end of the first linear module 31. The first linear module 31 can be set as a ball screw linear module. The inclined clamping mechanism includes: a servo cylinder 32, a first fixed sleeve 33, a first sliding rod 34, and a V-shaped support frame 35. The two servo cylinders 32 are respectively fixedly installed on the left and right sides of the output end of the first linear module 31. A plurality of first fixed sleeves 33 are fixedly installed on the output end of the first linear module 31. The first sliding rod 34 is slidably connected to the first fixed sleeve 33. The V-shaped support frame 35 is fixedly installed on the upper side of the first sliding rod 34. The middle side of the V-shaped support frame 35 is fixedly connected to the output end of the servo cylinder 32.

[0041] The flipping and loading device 2 is used to convey and flip the circuit board so that the circuit board is conveyed to the multi-station clamping device 3 at a certain inclination angle. The multi-station clamping device 3 clamps and fixes the circuit board at a certain angle. The multi-angle welding device 4 welds the circuit board at multiple angles. While avoiding the parts on the circuit board, the two circuit boards are welded together. The blanking device 5 unloads the welded circuit board.

[0042] The left and right movement of the output end of the first linear module 31 of the multi-station clamping device 3 drives the inclined clamping mechanism to move left and right. At this time, the circuit board on the inclined clamping mechanism on the left side of the bottom plate 1 is being welded, and the inclined clamping mechanism in the middle side of the bottom plate 1 is performing the loading and clamping positioning of the circuit board, realizing the dual-station loading and welding, and avoiding the coincidence of the waiting time between each station.

[0043] The downward movement of the output end of the servo cylinder 32 of the inclined clamping mechanism drives the V-shaped support frame 35 to move downward by a preset distance. The first fixed sleeve 33 and the first sliding rod 34 are used to assist the up and down sliding of the V-shaped support frame 35.

[0044] The inclined clamping mechanism further includes: a second fixed sleeve 36, a second sliding rod 37, an L-shaped sliding plate 38, a limiting plate 39, and a spring 312. A plurality of the second fixed sleeves 36 are fixedly installed on the V-shaped support frame 35. The second sliding rod 37 is slidably connected to the second fixed sleeve 36. A plurality of the L-shaped sliding plates 38 are respectively slidably connected to the left and right sides of the V-shaped support frame 35. The limiting plate 39 is fixedly installed at one end of the second sliding rod 37 close to the central axis of the V-shaped support frame 35. One end of the L-shaped sliding plate 38 away from the V-shaped support frame 35 is fixedly connected to one end of the second sliding rod 37 away from the limiting plate 39. The spring 312 is arranged on the second sliding rod 37. One end of the spring 312 abuts against the L-shaped sliding plate 38, and the other end of the spring 312 abuts against the V-shaped support frame 35.

[0045] The inclined clamping mechanism further includes: a special-shaped bracket 310 and rollers 311. A plurality of the special-shaped brackets 310 are fixedly installed on the output end of the first linear module 31. A plurality of rollers 311 are rotatably connected to each of the special-shaped brackets 310 through a rotating shaft.

[0046] The downward movement of the V-shaped support frame 35 by a preset distance drives the L-shaped sliding plate 38 to move downward by a preset distance. The L-shaped sliding plate 38 contacts the plurality of rollers 311 on the special-shaped bracket 310. The rollers 311 are used to reduce the friction between the L-shaped sliding plate 38 and the special-shaped bracket 310. At this time, the L-shaped sliding plate 38 moves towards the central axis of the V-shaped support frame 35. The circuit board is fed into the middle side of the V-shaped support frame 35 through the flipping feeding device 2. The spring 312 is compressed. The L-shaped sliding plate 38 moves a preset distance and then stops moving. The L-shaped sliding plate 38 does not fully clamp the circuit board on the middle side of the V-shaped support frame 35. The L-shaped sliding plate 38 pre-clamps the circuit board to limit the circuit board so that it will not move up and down.

[0047] Embodiment 2: In some embodiments, as Figures 1 - 12 shown, as a preferred embodiment of the present invention, the flipping feeding device 2 includes: a first bracket 21, a first belt conveyor 22, a second bracket 23, a first cylinder 24, and a vertical baffle 25. The first bracket 21 is arranged on one side of the bottom plate 1. The first belt conveyor 22 is fixedly installed on the first bracket 21. The second bracket 23 is fixedly installed at one end of the first belt conveyor 22 close to the center of the bottom plate 1. The first cylinder 24 is fixedly installed on the second bracket 23. The vertical baffle 25 is fixedly installed at the output end of the first cylinder 24.

[0048] The first belt conveyor 22 of the flipping feeding device 2 conveys the circuit board. The shortening of the output end of the first cylinder 24 drives the vertical baffle 25 to move upward. At this time, the circuit board can be normally conveyed.

[0049] The flipping and loading device 2 further includes: a second belt conveyor 26 and a second cylinder 27. One end of the second belt conveyor 26 is hinged to one end of the first belt conveyor 22 close to the center of the bottom plate 1. One end of the second cylinder 27 is hinged to one end of the first bracket 21 close to the center of the bottom plate 1, and the other end of the second cylinder 27 is hinged to the second belt conveyor 26.

[0050] The circuit board is conveyed by the first belt conveyor 22 to the second belt conveyor 26, and the output end of the second cylinder 27 shortens to drive. The second belt conveyor 26 rotates to flip the circuit board on the second belt conveyor 26 to a preset angle.

[0051] The flipping and loading device 2 further includes: a third bracket 28, a third cylinder 29 and a C-shaped plate 210.

[0052] The output end of the third cylinder 29 moves upward to drive the C-shaped plate 210 to move upward. The upward movement of the C-shaped plate 210 causes the blockage of the circuit board to be removed. At this time, the circuit board can move downward along the second belt conveyor 26 normally. When the circuit board is conveyed by the second belt conveyor 26 to the multi-station clamping device 3, the output end of the third cylinder 29 locks short, and then the output end of the third cylinder 29 extends to drive the C-shaped plate 210 to move downward. The inclined surface at one end of the C-shaped plate 210 contacts the circuit board on the multi-station clamping device 3 and pushes the circuit board to the standard position of the multi-station clamping device 3. At this time, the front and rear positions of the circuit board are quickly aligned.

[0053] The output end of the servo cylinder 32 of the inclined clamping mechanism moves downward a preset distance to drive the V-shaped support frame 35 to continue moving downward a preset distance. The downward movement of the V-shaped support frame 35 by a preset distance drives the L-shaped sliding plate 38 to move downward a preset distance. The L-shaped sliding plate 38 is restricted by a plurality of rollers 311 on the special-shaped bracket 310. The L-shaped sliding plate 38 moves in the direction of the central axis of the V-shaped support frame 35. The circuit board is loaded into the middle side of the V-shaped support frame 35 through the flipping and loading device 2, and the spring 312 is further compressed. The L-shaped sliding plate 38 moves a preset distance and then stops moving. At this time, the L-shaped sliding plate 38 completely clamps the circuit board in the middle side of the V-shaped support frame 35.

[0054] The first belt conveyor 22 and the second belt conveyor 26 of the two flipping and loading devices 2 convey the circuit boards at different times, so that the circuit boards enter the multi-station clamping device 3 one after another and are clamped, so that the sequence between the two circuit boards is the same each time, and the relative positions between the two circuit boards are fixed, indirectly improving the welding quality of the circuit boards.

[0058] The downward movement of the sliding bracket 44 drives the arc-shaped electric slide rail 46 and the automatic soldering gun 47 to move downward. The automatic soldering gun 47 cooperates with the first linear module 31 and the inclined clamping mechanism to realize the drag soldering of two circuit boards. The front and rear movement of the output end of the arc-shaped electric slide rail 46 drives the automatic soldering gun 47 to move back and forth to adjust the angle of the automatic soldering gun 47, so as to avoid the overly prominent electronic components on the circuit board.
