Description

Technical Field

[0001] The utility model relates to the technical field of screw locking equipment, in particular to a CPU bracket screw locking machine. Background Art

[0002] Currently, the CPU bracket and motherboard are mainly locked together by the operator manually aligning the CPU bracket with the motherboard, ensuring that the holes in the bracket are aligned with the holes on the motherboard, using a screwdriver to pass the screws through the holes in the bracket and screw them into the screw holes on the motherboard, and gradually tightening the screws to ensure that the bracket and motherboard are tightly connected, while avoiding over-tightening that may damage the screws or deform the motherboard. However, during the locking operation between the CPU bracket and the motherboard, due to the small size of the screws, the screws may fall from the operator's hands and fall onto the motherboard, which may cause damage to the electronic components on the motherboard. In addition, the operator cannot ensure that the screws are completely aligned with the screw holes by visually aligning the screws and screw holes, and there may be an angle offset, causing the screws to lock eccentrically, resulting in thread slippage or damage to the motherboard. In addition, manual locking of the CPU bracket and the motherboard is prone to being overtightened or too loose. Overtightening can easily cause deformation of the motherboard, while over-loosening can easily cause the CPU bracket to fall off the motherboard. Utility Model Content

[0030] In this embodiment, the extraction module 202 is driven to move to the silo 1 by the transfer module 201, and the extraction module 202 extracts the screws in the silo 1. The transfer module 201 drives the extraction module 202 to move to the first visual module 3, and the first visual module 3 identifies whether the angle of the screw extracted by the extraction module 202 is correct. If there is an offset, the currently extracted screw is discarded; the second visual module 4 is driven to move above the screw locking station by the transfer module 201, and the screw locking hole position 15 of the CPU bracket 14 and the motherboard 13 is identified by the second visual module 4. After the screw locking hole position 15 is determined, the transfer module 201 drives the extraction module 202 and the screw locking module 203 to move above the screw locking hole position 15, and the screws extracted by the extraction module 202 are locked to the CPU bracket 14 and the motherboard 13 by the screw locking module 203.

[0034] In this embodiment, the screw locking module 203 is driven by the lifting drive component 6 to move downward along the Z axis, so that the screw locking module 203 locks the screws on the extraction module 202 to the screw locking holes 15, thereby locking the CPU bracket 14 and the motherboard 13; the lifting drive component 6 is a telescopic cylinder, and after the screw locking is completed, the lifting drive component 6 drives the screw locking module 203 to move upward along the Z axis to reset.

[0039] In an exemplary embodiment of the present application, a rack 7 is further included. A conveying mechanism 8 is provided on the rack 7. The conveying mechanism 8 is used to transport a carrier loaded with the mainboard 13 .

[0048] In this embodiment, a baffle 12 is provided at the screw-locking station to prevent screws from falling from the extraction module 202 and damaging the motherboard 13. A through-hole 1201 is provided in the baffle 12 corresponding to the screw-locking hole 15. The screw-locking holes 15 of the CPU bracket 14 and the motherboard 13 at the screw-locking station are coaxial with the through-hole 1201 of the baffle 12. Therefore, the second visual module 4 can identify the screw-locking hole 15 by identifying the through-hole 1201 on the baffle 12. Furthermore, by providing the through-hole 1201 in the baffle 12, the screw-locking module 203 can pass through the baffle 12 through the through-hole 1201 to perform the screw-locking operation between the CPU bracket 14 and the motherboard 13.

The transfer module 201 drives the extraction module 202 to move to the first visual module 3, and the first visual module 3 identifies whether the angle of the screw extracted by the extraction module 202 is correct. If there is an offset, the currently extracted screw will be discarded; the transfer module 201 drives the second visual module 4 to move above the screw locking station, and the second visual module 4 identifies the screw locking hole position 15 of the CPU bracket 14 and the motherboard 13.
