Description

Technology Field

[0001] The present invention relates to a pipe processing dimension measuring device, and more specifically, to a device for measuring and classifying the processing dimensions of pipes used as tubular bodies for automobiles using an automated method utilizing vision. Background Technology

[0003] Generally, vehicles include various systems. For example, a vehicle includes systems such as brake lines, fuel lines, power steering lines, air conditioning lines, and low-pressure lines, and automotive hoses may be used in these systems. In the case of these automotive hoses, in addition to the basic performance required as a conduit depending on the system, they may possess different mechanical properties and fluidity as a tubular body required by each system.

[0004] Vehicle hoses are often joined to tubular pipes. Since pipes are often made of metal, if any products do not meet dimensional accuracy standards, the final product becomes defective; therefore, it is necessary to quickly sort and discharge them even in the middle of the process.

However, the present invention may be implemented in various different forms and is therefore not limited to the embodiments described herein. Furthermore, in order to clearly explain the present invention in the drawings, parts unrelated to the explanation have been omitted, and similar parts throughout the specification have been given similar reference numerals.

[0020] Throughout the specification, when it is stated that a part is "connected (connected, in contact, combined)" with another part, this includes not only cases where they are "directly connected," but also cases where they are "indirectly connected" with other members interposed between them. Furthermore, when it is stated that a part "includes" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but rather allows for the inclusion of additional components.

[0021] The terms used herein are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as “comprising” or “having” are intended to indicate the presence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0022] In this specification, "module" includes a unit composed of hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be a component formed as a whole, or a minimum unit or part thereof that performs one or more functions. For example, a module may be composed of an application-specific integrated circuit (ASIC).
