Description

Paper tube firework lump detection method Technical Field The invention relates to the technical field of paper tube firework detection, in particular to a paper tube firework lump detection method. Background Fireworks as an entertainment product for generating acousto-optic color are widely applied to popular ceremony or performance, and along with the increasing of the physical living standard of people, the use of combined fireworks is also carried into thousands of households. In the production process of the combined firework, operation and process detection are carried out on all working procedures on the premise of artificial implementation, along with continuous improvement of importance of production safety and improvement of production efficiency, the existing combined firework production generally realizes semi-automatic production of a production line, and the combined firework is produced and detected in a man-machine combination mode, so that the production efficiency is improved, the production cost of firework factories is reduced, and meanwhile, the production safety of the combined firework is guaranteed. Traditional paper tube fireworks lump detection mode is manual visual inspection, carries out paper tube shape integrality, lead quality (including lead number, lead length and poor pin lead etc.) to paper tube fireworks lump through the mode of people's eye observation to discernment lead, paper tube shape have defect. The defects of the quality of the leads (including the number of the leads, the length of the leads, poor leads and the like) cause that fireworks cannot be normally set off, and the shape change of the paper tube such as shrinkage and extrusion deformation can affect the subsequent automatic production, such as incapability of normally pressing paper sheets, incapability of normally placing the inner cylinder into the inner cylinder and the like. When the human eyes observe the lead wires, the lead wires are positioned at the bottom of the paper tubes due to the fact that the inner diameter of the single paper tube is smaller and the depth of the paper tube is deeper, the human eyes observe the lead wires by using an external light source, and eyes need to concentrate on observation points to a high degree. During production, the defects such as paper tube shape integrity, lead quality (including lead number, lead length, poor lead and the like) and the like cannot be detected normally, and serious quality defects of paper tube firework lump are caused due to long-time high observation by naked eyes. Effects of conventional modes of operation: 1. the manual operation needs continuous visual inspection work, and visual fatigue is easy to generate; 2. mass quality accidents are easy to occur when production personnel neglect; 3. the shape of the firework lump without shaping is irregular, and the shape quality of the product is affected. Disclosure of Invention In order to solve the problems in the prior art, the invention provides a paper tube firework lump detection method. The technical scheme of the invention is that the paper tube firework lump detection method comprises the following steps: Shaping the paper tube firework lump by adopting shaping equipment, so that the regular cross section shape of the paper tube firework lump and the accurate arrangement positions of all paper tubes are ensured; photographing detection equipment photographs all single cylinders of the shaped paper tube firework lump, and records the photographed single cylinders as a first group of data; Step 3, surrounding and guiding deformation, namely, guiding the outside of the firework barrel to be extruded or stretched by a deformation assembly so as to enable the lead wires in the firework barrel to move; photographing and detecting for the second time, wherein photographing and detecting equipment photographs all single cylinders of the paper tube firework lump after surrounding deformation and records the photographed single cylinders as a second group of data; and 5, comprehensively judging the data, and judging whether the paper tube firework lump is qualified or not by the background according to the first group of data and the second group of data. As a further improvement of the above technical scheme: preferably, the judging of the two sets of data in the step 5 mainly includes the lead length, the lead number, the poor lead and the paper tube firework lump shape. Preferably, the step 5 further includes determining the length of the leads and the number of the leads, and the main criteria of the determination are: Step 51, judging that the paper tube firework lump is a defective product if the lead length is insufficient or the lead is missing in both sets of data; and 52, judging that at least one group of leads are qualified, and judging that the paper tube firework lump is qualified. Preferably, the shaping equipment comprises a shaping workbench, a limiting plate arranged on the
