[0002] In the mechanical field, as fastener screw is generally used with gasket, manual screw is usually put through gasket, when there is a great demand for screw with gasket in a short time, manual assembly method is extremely low in efficiency, and often cannot meet the application of efficient manufacturing.

[0003] The existing electrical fittings screw usually needs to be assembled with several gasket assemblies, and then can be put into use, but such assembled screw usually needs to be installed at multiple angles, and the combined screw is more three-dimensional, and the existing mechanical gripper and other components are extremely low in working efficiency, and cannot continuously work systematically, so a device for assembling electrical fittings screw is needed. SUMMARY

[0008] Further, the copper sheet storage box comprises a copper sheet straight vibrator, and the top of the copper sheet straight vibrator is fixedly connected with a right-angle guiding slide rail. Since the copper sheet is a small-sized bent plate body with a bending angle close to a right angle, in order to enable the copper sheet to stably slide along the inner wall of the right-angle guiding slide rail, a right-angle slot matching the copper sheet is formed in the inner wall of the right-angle guiding slide rail. The end of the right-angle guiding slide rail away from the copper sheet straight vibrator is slidably connected with a transfer slide plate, and the end of the right-angle guiding slide rail away from the transfer slide plate is fixedly connected with the inner cavity of the copper sheet storage box. The front end of the transfer slide plate is fixedly connected with a copper sheet distribution cylinder, and the transfer slide plate can slide in a direction perpendicular to the right-angle guiding slide rail under the traction of the copper sheet distribution cylinder. A right-angle slot matching the copper sheet is also formed in the end of the transfer slide plate away from the copper sheet distribution cylinder, and is used to receive the copper sheet sliding along the right-angle guiding slide rail.

[0011] Further, the screw reversing component comprises a screw loosening up-down air cylinder, the upper surface of the screw loosening up-down air cylinder is fixedly connected with a loosening shaft, the bottom end of the loosening shaft is fixedly connected with a screw loosening clamping jaw, and the bottom end of the screw loosening up-down air cylinder is fixedly connected with the bottom of the container inner wall.

[0012] The beneficial effects of the present application are as follows:

[0013] 1. When the device is used for assembling the electrical accessory screw, the screw and the gasket are first assembled and transported, and then assembled with the copper sheet which has a relatively complex structure, thereby avoiding the problem that the screw is difficult to align with the gasket and the copper sheet when they are simultaneously assembled, reducing the precision requirement of the assembled components, making the assembly work more logical and sequential, avoiding the problems of missing assembly and empty assembly, and greatly improving the assembly efficiency, the yield and the economic benefits.

[0014] 2. Before the screw is inserted into the combined socket and assembled with the gasket, the screw is first placed on the screw vacuum suction plate for temporary storage, so that the gasket is first installed in the combined socket, and then the screw on the screw vacuum suction plate is inserted into the combined socket to ensure the docking work.

[0015] 3. The copper sheet is transported by a specially designed right-angle guide slide rail, since the inner wall of the right-angle guide slide rail is provided with a right-angle slot complementary to the copper sheet, the copper sheet can not slide out of the inner wall of the right-angle guide slide rail under the limitation of the right-angle slide groove, avoiding the problem of falling off when the copper sheet slides, the transportable transport slide plate can block the end of the right-angle guide slide rail on one side of the docking port, so that the copper sheet is temporarily retained in the right-angle guide slide rail, thereby preventing the problem that the transport speed of the copper sheet in the right-angle guide slide rail is too fast and exceeds the transport capacity of the transport slide plate, causing the copper sheet feeding component to be stuck.

[0016] 4. In the process of transporting the accessory screw to the blanking plate, the screw reversing component will scan the accessory screw inside the screw blanking opening cylinder, and through the screw loosening clamp jaw, the over-tightened screw will be rotated in the opposite direction, the over-tightened state of the accessory screw will be released, and the problem that the copper sheet of each accessory screw is easily broken due to over-tightening of the screw will be solved, and the hidden danger caused by the system processing will be eliminated.
