DETAILED DESCRIPTION

[0020] Figures 1 to 4 As shown, it relates to a welding mechanism for the production of switching power supplies, including a workbench 2, one end of the lower surface of the workbench 2 is symmetrically fixedly connected with a support leg 1, and the other end of the lower surface of the workbench 2 is fixedly connected with a cabinet 3, and the interior of the cabinet 3 can be used to place tools or electrical equipment required for daily switching power supply welding, and the cabinet 3 can jointly assume the support function of the workbench 2 with the two support legs 1;

[0021] At the same time, one end of the upper surface of the workbench 2 is fixedly connected to an L-shaped support plate 9, and an electric push rod 10 is fixedly installed on the upper surface of the L-shaped support plate 9. The output end of the electric push rod 10 extends through and extends to the bottom of the L-shaped support plate 9 and is fixedly connected to a mounting box 11. A pressing mechanism is installed inside the mounting box 11. The extension and retraction of the output end of the electric push rod 10 can drive the pressing mechanism to move up and down.

[0022] The pressing mechanism includes a T-shaped slider 21 which penetrates and slides through the top and bottom of the inner wall of the installation box 11, respectively. The function of the T-shaped slider 21 is that its horizontally placed top can slide on the bottom of the inner wall of the installation box 11 without falling off due to gravity, and the opposite sides of the two T-shaped sliders 21 are fixedly connected with a rack 14, and the opposite sides of the two racks 14 are meshed and connected with a gear 13, and the ends of the two racks 14 outside the installation box 11 are fixedly connected with an extension rod 16, and one end of the two extension rods 16 is fixedly connected with a connecting rod 17, and the lower surfaces of the two connecting rods 17 are fixedly connected with rubber pressure blocks 18;

[0023] Among them, a first servo motor 12 is fixedly installed on the front of the installation box 11, and the output shaft of the first servo motor 12 extends through the interior of the installation box 11 and is fixedly connected to the axis of the gear 13. The operation of the first servo motor 12 can drive the rotation of the gear 13. When the gear 13 rotates, the two racks 14 meshed and connected on the upper and lower sides thereof will move in opposite directions. If one moves to the left, the other moves to the right, so that they can extend outward from the interior of the installation box 11 at the same time, driving the two extension rods 16 and the connecting rod 17 to also move in the direction away from the installation box 11, so that the distance between the two rubber pressing blocks 18 is adjusted, so as to adapt to the circuit boards of switching power supplies of different sizes and press their edges;

[0024] At the same time, the side walls at the top and bottom of the installation box 11 are symmetrically provided with notches 15 that match the T-shaped slider 21 and the rack 14, so as to avoid obstruction when the toothed side of the rack 14 slides outwards.

[0025] A partition 5 is fixedly connected to the other end of the upper surface of the workbench 2, and a connecting seat 7 is fixedly connected to one side of the outer surface of the partition 5. An elastic buckle 8 is fixedly connected to the upper surface of the connecting seat 7. A soldering gun 6 is clamped on the upper surface of the elastic buckle 8. The soldering gun 6 is electrically connected to the controller 4, and the controller 4 is fixedly installed on the other side of the outer surface of the partition 5. The elastic buckle 8 is used to provide a hanging and clamping position for the soldering gun 6 when it is idle, which is conducive to the storage of the soldering gun 6. At the same time, when the soldering gun 6 is used, it can be pulled out from the elastic buckle 8 ( Figure 1 It is a schematic diagram. In actual use, the connection line of the soldering gun 6 is longer so that the staff can change the position at will).

[0026] A second servo motor 19 is fixedly installed on one end of the upper surface of the workbench 2, and the output shaft of the second servo motor 19 is fixedly connected to a placement plate 20, and the placement plate 20 is located directly below the L-shaped support plate 9. The upper surface of the placement plate 20 can be used to place the circuit board of the switching power supply, and the operation of the second servo motor 19 can drive the placement plate 20 to rotate, so that the staff can easily perform welding operations on different positions of the circuit board without changing the orientation relative to the workbench 2.

[0027] When using the welding mechanism for the production of switching power supplies, first place the circuit board of the switching power supply at the center of the upper surface of the placement plate 20 (wherein the rubber pressing block 18 is in the shape of a long strip, and its main structure connected to the installation box 11 is located at the rear side of the upper surface of the placement plate 20, and the placement plate 20 has only the front sides of two strip-shaped rubber pressing blocks 18 near the center and the front side, so as not to interfere with the sight of the welder during the welding operation), then start the electric push rod 10, and the extension and retraction of the output end of the electric push rod 10 can drive the lifting and lowering of the installation box 11, so that the edge of the circuit board of the switching power supply is pressed by the two rubber pressing blocks 18, which is convenient for the welder to operate. When the circuit board is placed for welding, it is easy to offset and cause welding errors. At the same time, the operation of the first servo motor 12 can drive the two racks 14 to extend out of the installation box 11, so that the distance between the two rubber pressing blocks 18 can be adjusted to adapt to different sizes of circuit board models of different switching power supplies.
