Service HotlineIn the existing industrial technology field, screws are mostly used for the connection between components. For many electronic products, because the products are more and more thin and light, the connection between the shell and the shell is often affected by the thickness of the shell. , usually need to use screw column structure for connection. Take the existing outdoor three-proof mobile phone as an example: the screw column structure includes a shell, a shell and a screw, the shell is provided with a plurality of screw columns, and the nuts in the screw columns are injected through the in-mold injection process. Directly integrated with the housing. Due to the special use environment and use requirements of outdoor three-proof mobile phones, they need to have good high-strength anti-drop performance, while the three-proof mobile phones in the prior art are subjected to high-strength drop tests due to the fundamental stress concentration of the screw column. During the process, problems such as cracking of the screw column or breaking from the root occur.
Sprinkle the excess flat washer 6 on the positioning plate II3-1 on the flat washer positioning plate 3, and shake the flat washer positioning plate 3 by hand. After a short time, the flat washer 6 will be positioned and arranged on the upper positioning plate II3-1. In the flat washer hole 3-7, since the width of the opening groove 113-32 of the baffle plate II3-3 is smaller than the diameter of the flat washer hole 3-7, and the thickness of the upper positioning plate II3-1 is designed according to the thickness of the flat washer 6, each Only one flat washer 6 can be accommodated in the flat washer holes 3-7 of each upper positioning plate II3-1, and then use a brush to remove the excess flat washer
flat washer is a part that is placed between the connected part and the bolt to protect the surface of the connected part from being scratched by the nut and to disperse the pressure of the nut on the connected part. At present, a flat washer in the prior art generally includes a washer body; the washer body has a bolt hole in the middle for a bolt to pass through. Although the flat washer of the above structure has a simple structure, it still has a disadvantage. When the flat washer is cushioned between the connected part and the bolt, the bolt head is usually exposed outside the connection part, so the bolt head is easy to It is damaged under the impact of external force, thus affecting its fixing effect.
The more complex inlaid embedded copper nut copper insert nut specification is M8, this copper insert nut is embedded in the injection molded part of the car, 5 twill embossing, 4 left twill embossing, 1 right twill embossing Knurling. Since there are multiple rolling patterns, double tool rests + double embossing rests are used, and 5 grooves and 2 chamfers are inserted at one time by a widening forming knife. The hot-pressed copper insert nut contains Reticulated and straight lines, the outer circle is conical, in the process of hot pressing to facilitate smooth introduction into the plastic hole.
An automatic screw-removing device for automatically removing screws on a workpiece, the automatic screw-removing device comprising a worktable, a manipulator disposed on one side of the worktable, and a screw-removing mechanism installed on the manipulator, The screw-removing mechanism includes an installation plate connected to the manipulator, an electric batch installed on the installation plate, a bit head disposed on one side of the electric batch, and a visual recognition unit disposed on the installation plate , the visual recognition unit takes pictures of the screw to determine the coordinates of the screw, the bit is rotated under the drive of the electric batch to disassemble the screw, the bit is magnetic and can be adsorbed the screw.
