Description

Technical Field

[0001] The invention relates to a riveting hole measuring device for a crank of a wiper system of a new energy vehicle. Background Art

[0002] In today's automotive industry, new energy vehicles are experiencing rapid development, with the market size continuing to expand and demand for them increasing daily. As a key system for ensuring safe operation of new energy vehicles in rainy and snowy conditions, the stability of the wiper system is crucial. The quality and stability of the crank, a functional component of the wiper system, directly determines the reliability of wiper control.

[0003] The industry has extremely stringent requirements for the accuracy of crank riveting holes, and there are also strict standards for the tear zone depth of punching holes. At present, aperture measurement mainly relies on three-coordinate data, and the tear zone depth relies on visual judgment. However, existing measurement methods have many drawbacks. Traditional measuring equipment is inefficient. In order to prevent the outflow of defective products, full inspection can only be carried out with the help of stop-gap gauges, which undoubtedly requires a lot of manpower and brings a heavy burden to the company. Moreover, during the manual inspection process, inspectors are very likely to suffer from visual fatigue due to long hours of work, which can lead to operational errors, missed inspections and other problems. These defects may cause customer complaints, and in serious cases, even lead to line stoppages and claims, forcing manufacturing companies to bear huge losses and risks.

[0004] To overcome this dilemma, the industry has attempted to introduce CCD technology, or vision systems, to measure hole diameter and tear depth. However, this technology has proven to have significant drawbacks. For one thing, vision systems require extremely high hole verticality for hole diameter measurement. If the verticality of a punched hole exceeds a certain range, the discrepancy between the CCD measurement result and the three-dimensional coordinate measurement result will increase significantly, failing to meet measurement accuracy requirements. Furthermore, vision systems cannot accurately identify burrs smaller than 0.02 mm within the hole. This can result in a pass measurement result but a failed go gauge, seriously impacting the customer's actual assembly. Furthermore, vision systems struggle to detect tear depth within punched holes. Even with a 360° endoscope, the image can only be determined by comparison with a sample. However, the sample does not capture the diverse conditions encountered in actual production, significantly compromising accuracy. While using a go / no-go gauge for inspection offers high accuracy, it is inefficient and requires manual labor.

[0005] Therefore, how to design a more efficient, accurate and reliable crank rivet hole measurement technology to meet the needs of new energy vehicle production is a technical problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0006] The purpose of the present invention is to address the deficiencies of the above-mentioned prior art and provide a device for measuring riveted holes in cranks of wiper systems of new energy vehicles. The device detects the workpiece in the clamping device by alternating the laser detection heads on the upper and lower detection heads, thereby reducing the time for manual detection and increasing the accuracy of detection.

[0011] Furthermore, it also includes an unloading device, which is installed on the upper panel for reciprocating movement back and forth. The unloading device is arranged on one side of the clamping device. After the clamping device moves to the opposite side of the unloading device, the unloading device moves toward the clamping device and abuts against the clamping device.
