Description

Automatic change scissors foot assembly clamping head

Technical Field

The invention relates to the field of automatic assembly of scissor legs, in particular to an automatic scissor leg assembly chuck.

Background

The scissor-foot keyboard uses the scissor-foot key switch as the name suggests. Has a scissor-shaped structure, and two groups of plastic wiping arms are arranged below each key. The working principle of the scissor feet is similar to the operation of scissors, the key stroke of the scissor foot keyboard is much shorter than that of the common rubber dome keyboard, the key caps of the keys are also lower in height due to the crossed arrangement and shorter stroke below the keys, the keys are mostly used for notebook computers, the keys of the keyboard are quite silent, the touch feeling is larger than that of the common film keyboard, the hand feeling is better, in addition, keys with different sizes such as a space key, a carriage return key, a letter key, a numeric key and the like are arranged on the keyboard, the scissor feet used by the keys with different sizes are different in size, when the scissor feet are installed and used, the scissor feet which are mixed together and have different sizes are sorted, and the scissor feet with different sizes are orderly transferred to an installation working section through a transferring device, meanwhile, the front faces of the scissor feet are ensured to face up in the sorting process, so that, and stable feeding and conveying are provided for subsequent installation sections.

Chinese patent CN214351932U discloses a chuck for scissors, comprising: the first end surface of the body is provided with a butting part which butts against the first side surface of the outer scissors frame; the two fixing pieces are oppositely arranged on two sides of the body, fixing parts of the fixing pieces deviate from the body along the extending direction of the body and extend out of the first end face, and the two fixing parts are clamped on the peripheral side of the outer scissor frame; the supporting part of the supporting part can slide to penetrate through the first end face in the extending direction of the body and then abut against the first side face of the outer scissor frame, and the supporting part and the abutting part are arranged in a staggered mode in the vertical direction to enable the outer scissor frame to be obliquely arranged relative to the horizontal plane.

Although above-mentioned scheme can realize carrying out the centre gripping to the scissors foot with certain angle, because current a feeding mechanism who is used for carrying the scissors foot is generally the level setting, consequently the scissors foot is also in the horizontality before being held, and current scissors foot chuck hardly carries out the centre gripping with the scissors foot of horizontality and becomes the state of slope, causes the circumstances such as centre gripping scissors foot inaccurate, drop easily to take place.
