A driving assembly is provided on the upper surface of the storage box 1. The staff operates the driving assembly to drive the door body 2 upward. The upward movement of the door body 2 will cause the connecting assembly to move. The movement of the connecting assembly drives the movement of the L-shaped connecting rod 9, and the movement of the rotating ring 8 is driven by the movement of the L-shaped connecting rod 9. , because the rotating ring 8 and the movable docking ring 7 are rotatably connected by the block and the slot, the rotating ring 8 will drive the movable docking ring 7 to move up synchronously, and because the movable docking ring 7 is slidably sleeved on the outer surface of the rotating rod 6 through the block and the slot, and the rotating rod 6 is rotatably connected to the inside of the storage box 1, when the movable docking ring 7 moves, it will not drive the rotating rod 6 to move.

The above structure improves the convenience of the staff in replacing the welding wire winding roller 5 as much as possible, avoids the problem of limited space inside the storage box 1, thereby improving the staff's replacement efficiency of the welding wire winding roller 5 and improving the overall practicality of the device.

[0030] Furthermore, the connecting component includes a connecting plate 16, which is slidably connected to the inside of the through slot 10, and the connecting plate 16 and the L-shaped connecting rod 9 are fixedly connected. Two sliding grooves 15 are provided on the front surface of the storage box 1. The left sliding groove 15 is connected to the through slot 10, and the insides of the two sliding grooves 15 are slidably connected with fixed rods 19. The two fixed rods 19 are fixedly connected to the door body 2.

Its general working principle is: pulling the welding wire body, through the transmission of the first pulley and the second pulley, will drive the reciprocating screw to rotate, so that the support frame connected to the outer side of the reciprocating screw is moved, and at this time the welding wire body moves in turn through one side of the support frame and the rubber plug, and at this time the welding wire body extends out of the outside of the storage box 1. The welding wire body is released according to the winding position, so that the position of the solder wire outlet is not fixed when the welding wire body is extended from the storage box 1, thereby preventing the welding wire body from getting stuck at the outlet angle when released, making it easier for the welding wire body to be extended, thereby improving the efficiency of the welding wire body during welding; when the welding wire body needs to be retracted and wound up, it is only necessary to rotate the handle 3, so that the extended welding wire body will be wound up through the transmission between the first pulley and the second pulley, and when the welding wire body is wound up, the reciprocating screw rod will rotate, so that the support frame will move back and forth, thereby avoiding the accumulation of the welding wire body when it is wound up.

[0034] Working principle:

[0035] When the welding wire storage mechanism for the semiconductor welding equipment is in use, the staff operates the driving assembly to drive the door body 2 to move upward, and the upward movement of the door body 2 will cause the connecting assembly to move, and the movement of the connecting assembly will drive the movement of the L-shaped connecting rod 9, and the movement of the L-shaped connecting rod 9 will drive the movement of the rotating ring 8. Because the rotating ring 8 and the movable docking ring 7 are rotatably connected by the block and the slot, the rotating ring 8 will drive the movable docking ring 7 to move upward synchronously, and because the movable docking ring 7 is slidably sleeved on the outer surface of the rotating rod 6 through the block and the slot, and the rotating rod 6 is rotatably connected to the inside of the storage box 1, when the movable docking ring 7 moves, it will not drive the rotating rod 6 to move, and the subsequent movement of the movable docking ring 7 will make The first docking teeth 11 and the second docking teeth 13 are separated, so that the movable docking ring 7 is no longer covered on the outside of the upper shaft 12. Then the staff pulls the placement plate 4 to move the welding wire winding roller 5 out of the outside of the storage box 1. The staff can then replace the welding wire winding roller 5. When the replacement is completed, the placement plate 4 is pushed back into the interior of the storage box 1 until the placement plate 4 and the rear surface and the inner wall of the storage box 1 are in contact. Then the driving assembly is operated again to lower the door body 2, thereby driving the connection assembly to move, so that the movable docking ring 7 is lowered until the movable docking ring 7 is covered on the outside of the upper shaft 12, and the first docking teeth 11 and the second docking teeth 13 are engaged, finally completing the installation of the welding wire winding roller 5. Although the embodiments of the present invention have been shown and described, it can be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
