Stepping motor cam friction mechanism

Abstract

The invention discloses a stepping motor cam friction mechanism. The stepping motor cam friction mechanism comprises a fixing groove and a plurality of friction guide units, wherein each friction guide unit comprises a first polished rod, a second polished rod, a first vertical plate, a second vertical plate, a connecting piece, an adjusting plate, a driving motor, a connecting block and an adjusting wheel; the first polished rod and the second polished rod are horizontally fixed in a fixing groove and are parallel to the width direction of the fixing groove; the first polished rod and the second polished rod penetrate through the first vertical plate and the second vertical plate; the first polished rod and the seconded polish rod are perpendicular to the first vertical plate and the second vertical plate; the connecting piece connects the first vertical plate and the second vertical plate; and the driving motor is fixed in the fixing groove and provided with a driving shaft, one endof the connecting block is connected with the driving shaft, the other end of the connecting block is connected with the adjusting wheel, the adjusting plate is vertically arranged and connected withthe connecting piece, an adjusting hole is formed in the adjusting plate and is in a vertical long-strip shape, and the adjusting wheel is inserted into the adjusting hole. Compared with the prior art, the stepping motor cam friction mechanism has the advantages of high positioning precision, low cost, simple structure and stable operation.

Description

technical field [0001] The invention relates to a friction mechanism, in particular to a cam friction mechanism of a stepping motor. Background technique [0002] With the rapid development of modern logistics technology, the express industry is booming, and express companies are faced with a large number of express sorting tasks every day. Traditional express sorting mostly relies on manual sorting, which is labor-intensive, low in efficiency, and high in error rate. Express workers are prone to make mistakes and lose items when sorting. At present, with the continuous increase in the labor cost of the express delivery industry and the continuous improvement of customer service quality requirements, manual sorting can no longer meet market demand, so automatic sorting express delivery equipment has also emerged as the times require. [0003] The applicant proposed a narrow-band logistics sorter with the application number CN201910369935.X on May 6, 2019. It includes a guid...

Problems solved by technology

Traditional express sorting mostly relies on manual sorting, which has high intensity, low efficiency, and high error rate. It is easy for express workers to make mistakes when sorting, and it is easy to lose items.

At present, with the continuous increase in the labor cost of the express delivery industry and the continuous improvement of customer service quality requirements, manual sorting can no longer meet market demand, so automatic sorting express delivery equipment has also emerged as the times require.

[0003] The applicant proposed a narrow-band logistics sorter with the application number CN201910369935.X on May 6, 2019, which includes a guiding structure, but the setting of the guiding structure still has a large room for improvement
