Description

Technical Field

[0001] The utility model relates to an inspection device, in particular to a continuous flash detection device for trimmed O-rings. Background Art

[0002] After trimming, the existing O-rings need to be inspected for appearance. The contents of the appearance inspection include surface flatness, smoothness, absence of cracks, breakage, deformation, burrs, rough edges, and absence of obvious trimming marks. Conventional appearance inspection is usually visible to the naked eye, but manual inspection is inefficient, the inspection effect is poor, and there may be cases of missed inspections. Due to the small structure of O-rings, manual inspection requires high vision. The existing technology mainly uses optical imaging equipment to realize batch inspection. There is an optical imaging device that can well complete the appearance inspection of O-rings after trimming, which is a flash tester. However, the flash tester requires the O-ring to be placed on a transparent platform manually and then taken down manually, which is inefficient. Utility Model Content

The top of the frame is provided with a pull-out test table mounted on the flash tester. The rear of the pull-out test table is provided with a support platform for placing the flash tester. The support platform is mounted on the frame.

[0006] The pull-out test bench includes a fixed frame mounted on a frame and a light frame that slides with the fixed frame to achieve pull-out. The fixed frame is equipped with an O-ring conveying mechanism. The light frame is provided with a plurality of light bar grooves with upward openings arranged side by side. LED light bars are installed in the light bar grooves. A light-transmitting window facing the flash tester is provided on the top of the fixed frame.

[0007] The O-ring conveying mechanism includes two annular conveying chains, conveying rollers supporting the annular conveying chains, and a driving mechanism connected to the conveying rollers. The lamp stand is arranged in the ring of the annular conveying chain. The annular conveying chain on the front side of the lamp stand is set as the entrance and exit of the lamp stand. The power supply circuit of the LED light strip is installed on the rear side of the lamp stand. Several flexible transparent plates are installed side by side between the two annular conveying chains. The two ends of the conveying rollers are installed on the frame through bearings. The output shaft of the driving mechanism is connected to the roller shaft of one of the conveying rollers.
