Description

Technical Field

[0001] This utility model relates to the field of magnetic tile production and testing technology, specifically to an automatic magnetic tile flipping visual inspection device. Background Technology

[0002] During the production of magnetic tiles, defects such as scratches, missing corners, and chipped edges may appear on the surface. These defects can affect the performance and service life of the magnetic tiles. Therefore, a comprehensive surface inspection of the magnetic tiles is necessary.

[0003] Currently, surface inspection of magnetic tiles mainly relies on manual visual inspection, which is inefficient, labor-intensive, and prone to missed or false detections. To improve inspection efficiency and accuracy, some companies have adopted visual inspection technology. However, existing visual inspection devices can only inspect one surface of the magnetic tile, requiring manual flipping of the tile to inspect the other surface, which still results in low efficiency and high labor intensity. Utility Model Content

[0004] In view of the above, the purpose of this utility model is to provide a magnetic tile automatic flipping visual inspection device, which can automatically flip the magnetic tile and perform comprehensive inspection on both sides, thereby improving inspection efficiency and accuracy and reducing labor intensity.

[0005] The magnetic tile automatic flipping visual inspection device in this solution includes a conveying mechanism, an automatic flipping mechanism, a first visual inspection station and a second visual inspection station.

[0006] The conveying mechanism is used for horizontal transport of magnetic tile workpieces;

[0007] An automatic flipping mechanism is located in the middle of the conveying path to guide the magnetic tile to complete a 180° flip;

[0008] The first and second visual inspection stations are respectively arranged on the front and rear sides of the automatic flipping mechanism. Both the first and second visual inspection stations include detection sensors, vision cameras, pneumatic sorting mechanisms, and defective product collection boxes. The detection sensors are used to sense the magnetic tile arrival signal; the vision cameras are used to receive the detection sensor signals and acquire images of the magnetic tile surface; the pneumatic sorting mechanism executes sorting actions based on the vision camera instructions; and the defective product collection box receives defective products discharged by the pneumatic sorting mechanism.

[0009] Furthermore, the automatic flipping mechanism includes a first baffle and a second baffle vertically arranged on both sides of the conveying mechanism, with a guide channel between them for the magnetic tiles to pass through; a spatial guide ridge is provided on one side inside the guide channel, and the height of the spatial guide ridge gradually increases from the entrance to the exit of the guide channel and gradually shifts towards the inside of the channel during the increase.

[0010] Furthermore, the spatial guide ridge is formed by a twisted steel plate disposed inside the guide channel. The width of the twisted steel plate is half the width of the guide channel, and the twisted steel plate gradually twists from a horizontal state to a vertical state towards the first baffle from the entrance to the exit of the guide channel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, by setting an automatic flipping mechanism, can automatically flip the magnetic tile 180°, realizing automatic detection of both sides of the magnetic tile, improving detection efficiency and accuracy, and reducing labor intensity.

[0013] The automatic flipping mechanism of this utility model uses a twisted steel plate to form a spatial guide ridge. It has a simple structure, reliable flipping, and can effectively avoid jamming and damage to the magnetic tile during the flipping process.

[0014] This invention features a receiving steel plate at the end of the guide channel, which can support the magnetic tile before it flips and falls, allowing it to fall slowly and further improving the reliability and stability of the flipping. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 4 The illustrated magnetic tile automatic flipping visual inspection device includes a conveying mechanism 1, an automatic flipping mechanism 2, a first visual inspection station 3, and a second visual inspection station 4. The conveying mechanism 1 is used for horizontally conveying magnetic tile workpieces; the automatic flipping mechanism 2 is located in the middle of the conveying path and is used to guide the magnetic tiles to complete a 180° flip; the first visual inspection station 3 and the second visual inspection station 4 are respectively arranged on the front and rear sides of the automatic flipping mechanism 2. Both the first visual inspection station 3 and the second visual inspection station 4 include a detection sensor, a vision camera 5, a pneumatic sorting mechanism 6, and a defective product collection box 7. The detection sensor is used to sense the magnetic tile's arrival signal; the vision camera 5 is used to receive sensor signals and acquire images of the magnetic tile surface; the pneumatic sorting mechanism 6 executes sorting actions based on instructions from the vision camera 5; and the defective product collection box 7 receives defective products discharged by the pneumatic sorting mechanism 6.

[0022] In this embodiment, the automatic flipping mechanism 2 includes a first baffle 201 and a second baffle 202 vertically disposed on both sides of the conveyor belt 101, forming a guide channel for the magnetic tile to pass through, providing a stable path constraint for the movement of the magnetic tile. The first baffle 201 and the second baffle 202 are internally provided with a twisted steel plate 204, the width of which is half the width of the guide channel. From the entrance to the exit of the guide channel, the twisted steel plate 204 gradually twists from a horizontal state towards the first baffle 201 to a vertical state, forming a spatial guide ridge 203 on the side away from the first baffle 201. The height of this spatial guide ridge 203 gradually increases from the entrance to the exit of the guide channel and gradually shifts towards the inner side of the channel, guiding the magnetic tile to gradually flip during movement. At the end of the guide channel, there are two receiving steel plates 205 with twisted surfaces. Before the magnetic tile flips and falls, the receiving steel plates 205 support the magnetic tile, allowing it to fall slowly after flipping, preventing damage due to excessive flipping speed.

[0023] In this embodiment, the detection sensor is a photoelectric sensor. When the magnetic tile passes by, the photoelectric sensor's occlusion signal is triggered, which in turn sends a photo-taking command to the vision camera 5.

[0024] The pneumatic sorting mechanism 6 includes an air nozzle 601 and a high-pressure air source. The air nozzle 601 is arranged on the side facing the conveying mechanism 1. The high-pressure air source is connected to the air nozzle 601 through a pipeline, and a solenoid valve is provided on the pipeline. The solenoid valve is electrically connected to the vision camera 5. When the vision camera 5 receives an NG signal, the solenoid valve opens, and the high-pressure air source blows the defective products away to the defective product collection box 7 through the air nozzle 601.

[0025] The conveying mechanism 1 includes a conveyor belt 101 and a conveyor belt motor 102, wherein the conveyor belt motor 102 drives the conveyor belt 101 to move at a constant speed in the horizontal direction.

[0026] Working Principle: In operation, the magnetic tile automatic flipping visual inspection device of this invention transports the magnetic tile to the first visual inspection station 3 via the conveying mechanism 1. Once the detection sensor detects the tile's arrival, it sends a photographing command to the visual camera 5. The visual camera 5 captures and processes the image of the magnetic tile surface to determine if any defects exist. If defects are found, the visual camera 5 sends an NG signal to the pneumatic sorting mechanism 6, which blows the defective product away to the defective product collection box 7. If no defects are found, the magnetic tile continues to be transported by the conveying mechanism 1 to the automatic flipping mechanism 2.

[0027] In the automatic flipping mechanism 2, the magnetic tile moves in the guide channel. The spatial guide ridge 203 guides the magnetic tile to gradually flip 180°. When the magnetic tile moves to the end of the guide channel, the receiving steel plate 205 receives the magnetic tile and makes it slowly fall down, completing the 180° flip.

[0028] After being flipped, the magnetic tile continues to be conveyed by the conveyor mechanism 1 to the second visual inspection station 4. The second visual inspection station 4 inspects the other side of the magnetic tile, and the inspection process is the same as that of the first visual inspection station 3. Finally, qualified products are conveyed by the conveyor mechanism 1 to the next process, while defective products are sorted into the defective product collection box 7.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
