Gear-driven type high-precision and high-speed rotary mounting head of intelligent chip mounter

Abstract

The invention discloses a gear-driven type high-precision and high-speed rotary mounting head of an intelligent chip mounter. The gear-driven type high-precision and high-speed rotary mounting head of the intelligent chip mounter comprises a rotary main shaft, a driving gear, a driven gear, Z-axis spline shafts, a rotating shaft main body frame, a rotating shaft, a servo motor A, a servo motor B, a servo motor C, a material camera and an MARK camera. The MARK camera performs material-taking identification, the servo motor C and the servo motor B receive pulses in the same frequency and are respectively engaged with the driving gear and the driven gear, the rotary main shaft rotates and drives the multiple Z-axis spline shafts to sequentially rotate to a material-taking position, then the servo motor A presses downwards to finish component attachment, and then the mounting head is moved into a mounting area at a high speed, the servo motor C stops rotation, the driving gear is locked, the servo motor B is rotated for an angle according to an instruction, the driven gear rotates and drives the Z-axis spline shafts to rotate for a corresponding angle, and then the servo motor A presses downwards to finish the mounting action. The gear-driven type high-precision and high-speed rotary mounting head of the intelligent chip mounter has the advantages of small occupied space, low cost, high speed, high precision and the like.

Description

Technical field [0001] The invention relates to a placement head, in particular to a gear-driven high-precision and high-speed rotating placement head for an intelligent placement machine. Background technique [0002] At present, in the SMT industry, the placement heads of the domestic placement machines are of a row-and-socket structure. The number of placement heads is small, the volume is large, but the speed is too slow; if the placement head is added, the volume will not only increase, but will be relatively fixed. In the space, the stroke of the placement head is reduced, so the placement area will be reduced. In addition, each placement head has an independent servo motion structure, increasing the number of placement heads, and the speed is relatively improved, but the cost is undoubtedly The biggest burden. Especially increase the number of placement heads, and also increase the load of the X and Y arms. The high-speed reciprocating motion and the strong inertial impac...

Problems solved by technology

[0002] At present, in the SMT industry, the placement heads of domestic placement machines are all plug-in structures. The number of placement heads is small and the volume is large, but the speed is too slow; if more placement heads are added, the volume will not only increase, but also relatively fixed. In the space, the stroke of the placement head is reduced, so the placement area will be reduced. In addition, each placement head has an independent servo motion structure, increasing the number of placement heads, the speed is relatively improved, but the cost is undoubtedly maximum burden

In particular, increasing the number of placement heads also increases the load of the X and Y arms. The high-speed reciprocating motion and the strong impact of the inertia of the acceleration will reduce the service life of the motion system, and the wear and tear of the equipment will also affect the accuracy.
