Description

Technical Field

[0001] This utility model relates to the field of screw-making machine technology, and in particular to a screw-making machine. Background Technology

[0002] On the production line, finished machines frequently require repair, and disassembling a large number of refurbished machines presents a problem. Currently, screw tightening can be fully automated, but disassembly cannot be fully automated because, after the screws are loosened, current screw-tightening machines cannot pick them up from the screw holes. Some screw-tightening machines have a magnet added to the end of the screwdriver bit, but the magnetism of this magnet does not disappear; it remains constant, preventing the actual picking up and putting down of the screws. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a screw-picking machine that solves the problem that screws cannot be picked up and transferred during disassembly in the prior art.

[0004] The solution adopted by this utility model to solve its technical problem is: a screwdriver, including an electric screwdriver shaft, a coil, and a control board, wherein the coil is set at the lower end of the electric screwdriver shaft so that the magnetic field generated by the coil is conducted to the screw to be removed. The coil includes an iron ring with a hole in the middle. The electric screwdriver shaft passes through the hole in the middle of the iron ring. The iron ring is wound with wires. The control board is electrically connected to the wires on the iron ring so that the control board generates magnetism when energized or loses magnetism when de-energized. The lower end of the electric screwdriver shaft is connected to an electric screwdriver bit for screwing.

[0005] In the above structure, the electric screwdriver spindle has a first wire hole and a second wire hole above the coil, and the electric screwdriver spindle is hollow so that the wire passes through the cavity in the middle.

[0006] In the above structure, the upper end of the electric screwdriver spindle is connected to the drive shaft, a first conductive ring is provided on the outside of the drive shaft, a second conductive ring is provided on the outside of the first conductive ring, the first conductive ring is connected to the wire passing through the first wire hole, and the second conductive ring is connected to the wire passing through the second wire hole. The length of the drive shaft is greater than the length of the first conductive ring, and the length of the first conductive ring is greater than the length of the second conductive ring. Both the first and second conductive rings are annular conductive metal rings.

[0007] The above structure also includes a first brush and a second brush, which are electrically connected to the control board. One end of the first brush is slidably connected to the first conductive ring and the other end is connected to the housing. One end of the second brush is slidably connected to the second conductive ring and the other end is connected to the housing.

[0008] The above structure also includes a switch, which is electrically connected to the control board so that the magnetism of the coil can be generated or lost during operation.

[0009] The technical effect of this utility model is as follows: by setting a coil at the lower end of the electric screwdriver shaft, and using a control board to energize or de-energize the coil to generate or eliminate its magnetism, the screw can be automatically magnetically attracted or dismounted, thus automating the screw removal process. The above description is merely an overview of the technical solution of this utility model. To better understand the technical means of this utility model and to implement it according to the description, and to make the above and other objects, features, and advantages of this utility model more apparent, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0013] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0014] It should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "inner," and "outer" used herein to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Unless otherwise stated, "a plurality of" means two or more.

[0015] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Referring to the accompanying drawings, a screwdriver includes an electric screwdriver spindle 1, a coil 2, and a control board. The coil 2 is disposed at the lower end of the electric screwdriver spindle 1 so that the magnetic field generated by the coil 2 is conducted to the screw to be removed. The coil 2 includes an iron ring with a hole in the middle. The electric screwdriver spindle 1 passes through the hole in the middle of the iron ring. The iron ring is wound with wires. The control board is electrically connected to the wires on the iron ring so that the control board generates magnetism when energized or loses magnetism when de-energized. An electric screwdriver bit for screwing is connected to the lower end of the electric screwdriver spindle 1.

[0017] Furthermore, the electric screwdriver spindle 1 is provided with a first wire hole 3 and a second wire hole 4 above the coil 2, and the electric screwdriver spindle 1 is hollow so that the wire passes through the cavity in the middle.

[0018] Furthermore, the upper end of the electric screwdriver spindle 1 is connected to the drive shaft 9. A first conductive ring 5 is provided on the outer side of the drive shaft 9, and a second conductive ring 6 is provided on the outer side of the first conductive ring 5. The first conductive ring 5 is connected to the wire passing through the first wire hole 3, and the second conductive ring 6 is connected to the wire passing through the second wire hole 4. The length of the drive shaft 9 is greater than the length of the first conductive ring 5, and the length of the first conductive ring 5 is greater than the length of the second conductive ring 6. Both the first conductive ring 5 and the second conductive ring 6 are annular conductive metal rings.

[0019] Furthermore, it also includes a first brush 7 and a second brush 8, which are electrically connected to the control board. One end of the first brush 7 is slidably connected to the first conductive ring 5 and the other end is connected to the housing. One end of the second brush 8 is slidably connected to the second conductive ring 6 and the other end is connected to the housing.

[0020] Furthermore, it also includes a switch, which is electrically connected to the control board so that the magnetism in coil 2 can be generated or lost during operation via the control board.

[0021] This invention automates screw removal by installing a coil 2 at the lower end of the electric screwdriver's rotating shaft 1. A control board energizes or de-energizes the coil 2, causing its magnetism to be generated or lost. This allows for the automatic magnetic attraction of screws, moving them to another location and then placing them down. During movement, the magnetic force must be maintained to attract the screw; to release the screw, simply de-energize the coil 2, causing its magnetism to disappear and the screw to fall naturally.

[0022] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
