Embodiment 1

[0030] Embodiment 1, the motion controller 7 controls the position of the imaging unit 2 relative to the fireworks tube 100, such as figure 1 , 2 As shown, the motion controller 7 controls the imaging unit 2 to move along the assembly line 8 to perform imaging processing on the back cover paper 200 and the gunpowder 300 of the fireworks tube 100 .

Embodiment 2

[0031] Embodiment 2, the position control of the fireworks tube 100 relative to the imaging unit 2, such as Figure 5 , 6 As shown, the motion controller 7 controls the fireworks tube 100 to move along the assembly line 8, and the two imaging units 2 respectively perform imaging processing on the back cover paper 200 and the gunpowder 300 of the fireworks tube 100.

[0032] The imaging unit 2 mainly includes a matrix camera 22 and a light source 23 fixed on an aluminum substrate support 21 .

[0033] The light source 23 is an LED lamp bead with an additional front light-transmitting mirror, and the same number of LED lamp beads are evenly distributed around a single camera.

[0034] The layout of the matrix camera 22 and the setting of the light source 23 are based on the specifications of the fireworks tube 100, and a front light-transmitting lens with a suitable angle is used to illuminate the fireworks tube. The front light-transmitting mirror is a kind of condensing lens...

Abstract

The present invention relates to a visual detection system and detection method for fireworks products, relates to the technical field of fireworks production, mainly comprises a computer and an imaging unit, and is responsible for taking images of inspection area of a fireworks barrel, then transmitting the images to a computer through an Ethernet interface; and the computer performs analysis andprocess of visual recognition on the collected images, and outputs processing results. The method has following beneficial effects: 1, the method can remotely observe detection and identification status, 2, the method provides automatic sound and light alarm for bad product detection, 3, the method achieves high efficient and clear deep-tube image retrieval at a lower cost, 4, the method has camera light source in integrated design, and facilitate simple and convenient installation, 5, the method facilitates easy remedy and elimination, 6, the method can complete process beat detection of fireworks every 3 seconds, 7, the method can work 24 hours without interruption, and 8, the method can save energy and reduce production costs such as manpower and time.

Description

technical field [0001] The invention relates to a visual detection system and detection method for fireworks products, belonging to the technical field of fireworks production. Background technique [0002] At present, in the fireworks production process, the production process is mainly to place a back cover sheet and launch gunpowder in the outer cylinder, and then place the inner cylinder. The outer cylinder is relatively high, and the inner hole is a deep cylinder, so it is necessary to image the deep cylinder of each outer cylinder, and it is difficult to take images with traditional industrial cameras, so it is very costly to use traditional industrial cameras to obtain images that meet the inspection requirements. high. The detection process focuses on three points, namely. At present, most of the quality control of each process adopts the most primitive manual inspection method, assisting the use of a flashlight to observe product defects with the naked eye; there ...
