Abstract

An automatic hub type identifying device and a method for identifying a hub type using the device are provided. The device includes a feed roller bed, an electronic belt scale, a transfer roller bed, an identification device, a discharge roller bed and a processor, in which the feed roller bed is configured to convey a hub to the electronic belt scale; the electronic belt scale is in data connection with the processor, and is configured to weigh the hub conveyed by the feed roller bed and transmit the weighing result to the processor; the transfer roller bed is configured to transfer the hub from the electronic belt scale to the identification device; and the identification device includes servo drive devices and micro contact displacement detecting devices connected to the servo drive devices.

First claim

The invention claimed is:

1. An automatic hub type identifying device, comprising a feed roller bed, an electronic belt scale, a transfer roller bed, an identification device, a discharge roller bed and a processor, wherein the feed roller bed is configured to convey a hub to the electronic belt scale; the electronic belt scale is in data connection with the processor, and is configured to weigh the hub conveyed by the feed roller bed and transmit a weighing result to the processor; the transfer roller bed is configured to transfer the hub from the electronic belt scale to the identification device; the identification device comprises a first servo drive device, a second servo drive device, a third servo drive device, a fourth servo drive device, a fifth servo drive device, a sixth servo drive device and a seventh servo drive device, each of these servo drive devices is connected to a contact position sensor, and each contact position sensor is in data connection with the processor; each of the first servo drive device, the second servo drive device, the fifth servo drive device and the sixth servo drive device is equipped with an industrial camera for identification of a position of a bead seat of the hub; the first servo drive device and the fifth servo drive devices are configured to drive the corresponding contact position sensors to measure a diameter of an inner bead seat of the hub; the second servo drive device and the sixth servo drive device are configured to drive the corresponding contact position sensors to measure a diameter of an outer bead seat of the hub; the fourth servo drive device and the seventh servo drive device are configured to drive the corresponding contact position sensors to measure a width of the hub; the hub the third servo drive device is configured to drive the corresponding contact position sensor to measure an offset value of the hub; the discharge roller bed is configured to carry the hub away from the identification device; the processor is configured to compare the weighing result of the electronic belt scale with a preset hub type-weighing result to obtain a possible range of a hub type; and the processor is also configured to compare the diameter of the inner bead seat, the diameter of the outer bead seat, the width of the hub and the offset value of the hub with a preset criteria to determine a unique type of the hub.

2. The automatic hub type identifying device according to claim 1 , wherein the first servo drive device, the second servo drive device, the third servo drive device, the fourth servo drive device, the fifth servo drive device, the sixth servo drive device, the seventh servo drive device and the corresponding contact position sensors are respectively located at an upper side edge of the hub, a lower side edge of the hub, a center of a back cavity of the hub, a front edge of a wheel disc and an end of a rim.

3. The automatic hub type identifying device according to claim 1 , wherein the first servo drive device, the second servo drive device, the third servo drive device, the fourth servo drive device, the fifth servo drive device, the sixth servo drive device, the seventh servo drive device and the corresponding contact position sensors are configured to measure coordinates of 4-6 feature points on the hub, and the feature points are selected from one or more points at a front side edge of a wheel disc, one or more points on humps of an outer rim, one or more points on the bead seat, one or more points on an inner rim, and one or more points on a front cap slot of the wheel disc.
