Benefits of technology

[0010]The technical solution of the present invention has the following advantages:
[0012](2) The device can further accurately identify the weight by using the industrial camera.
[0013](3) The device using servo drive has the characteristics of fast and stable operation and accurate and reliable positioning.
[0015](5) The device can accurately identify the hub type and then automatically complete the valve hole compensation function of balance detection through the combination of the above components, program control and an algorithm, thereby improving the automation level and reducing the repeated operation of an operator.

Problems solved by technology

The previous work relies entirely on the manual operation of an operator, and the weight substitute is manually removed after the balance detection, so this is a typical repetitive work, and the manual operation efficiency is low.

embodiment 2

hole detection device

[0027]As described in Embodiment 1, after different types of hubs 6 are preliminarily weighed by the electronic belt scale 8 and identified, the weight of the hub 6 is compared with the database of an industrial personal computer for rough analysis, then the hub 6 runs to the station of the industrial camera 7, and the unique type of the hub is identified.

[0028]For example, the weight of the hub 6 is measured to give a weight fluctuation range of ±100 g; the similarity of the measured photos of the hub 6 is matched by 95%; the criterion is that the wheel type having the similarity of more than 95% is subjected to weighing data comparison, and the type of the hub 6 is distinguished through the weight; and unique determination is performed on the hub 6 having the picture similarity of less than 95%, so that accurate identification on the type of the hub 6 can be ensured.

[0029]After the type of the hub 6 is determined, the weight value of the valve hole weight is c...

Abstract

A device for detecting the balance of a hub valve hole that includes a hub conveying roller bed configured to sequentially convey a hub from an upstream of a conveying belt to a hub identification device and a valve hole balance detection device until the hub leaves the valve hole balance detection device, wherein the hub identification device includes an electronic belt scale configured to obtain the weight of the hub and an industrial camera configured to take a photo of a wheel disc of the hub when the hub is conveyed to the hub identification device. The device can accurately identify the hub type and then automatically complete the valve hole compensation function of balance detection through the combination of the above components, program control and an algorithm, thereby improving the automation level and reducing the repeated operation of an operator.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Chinese Patent Application No. 201810271140.0, entitled DEVICE FOR DETECTING BALANCE OF HUB VALVE HOLE and filed on Mar. 29, 2018, which is incorporated herein by reference for all purposes.FIELD OF THE INVENTION[0002]The present invention relates to a hub valve hole detection device and an automatic weight compensation method.BACKGROUND OF THE INVENTION[0003]Balance detection is required after hub machining to identify balance rejects. Since the motor vehicle main engine plant requires the balance amount of a hub to meet the balance requirement of loading, a weight substitute having the weight and size matching the requirements of the main engine plant needs to be installed at a valve hole during balance detection of a hub. Since different wheel types have different weight requirements, the wheel type is manually identified during balance detection of a hub, and then a weight substitute is manually inst...
