Description

Technical Field

[0002] Circular guide rail conveyor lines play an important role in the handling and precise delivery of materials and products in automated production. The most commonly used transmission methods are belt drive or chain drive, where a servo system drives the sprocket or pulley to travel a fixed and equal distance to achieve circular transmission. There are also magnetic suspension circular guide rails on the market. Their working principle is that the permanent magnet on the slide is thrust by the magnetic field generated by the induction coil of the stator, and the slide moves along the guide rail; however, its control program is complicated, the price is relatively expensive, and the subsequent maintenance cost is also high. In response to the above problems, Chinese patent application number: CN202322684193.4 discloses a ring-shaped guide rail gear rack power supply device, including a frame, on which a conductive track, a power supply device, a circulating track and a circulating rack are arranged, a carrier plate is slidably mounted on the circulating track, a current collector, a servo drive system and a driving gear connected to the servo drive system are mounted on the carrier plate, the driving gear is meshed and connected with the circulating rack, the current collector is electrically connected to the conductive track through a sliding contact, and the power supply device is electrically connected to the conductive track through a power cord and energizes the conductive track. The utility model combines a circulating track as a working track and a circulating rack as a driving track, and provides power in a closed-loop circuit composed of a conductive track, a current collector and a power supply device. Each servo drive system can operate independently, so that the stroke can be independently controlled, and the structure is simple, and the subsequent maintenance cost is low.

[0003] However, the above-mentioned annular guide rail, gear rack and pinion power supply device still has the following problems: 1. It adopts a single guide rail and a single slider structure.

However, when it is necessary to carry heavier products, it may deviate, resulting in deviation, affecting the working stability and efficiency of the annular guide rail, gear rack and pinion power supply device, and the deviation causes damage to the roller, reducing the service life; 2. The slider structure of the existing annular guide rail, gear rack and pinion power supply device is composed of a plurality of eccentric roller bearings and concentric roller bearings. This method requires multiple adjustments to connect the slider structure to the guide rail, affecting the installation efficiency, and the eccentric roller bearings and concentric roller bearings have no positioning structure, resulting in height difference during installation, requiring multiple adjustments, affecting the installation efficiency, loosening after long-term use, resulting in height difference, causing the slider structure to vibrate during operation, affecting the normal use and accuracy of the high-stability rack guide device.
