Description

Technical Field

[0001] This utility model relates to the technical field of ceramic tile production equipment, and more specifically to a visual inspection device for defects in ceramic tile glazing. Background Technology

[0002] In the production of ceramic tiles, inspection is necessary, which involves detecting surface and body defects in the tile blanks. Surface defects include pinholes, glaze depressions, dirt, glaze residue, and missing glaze, while body defects include blank marks, chipped corners, edge breakage, damage, and cracks. Traditional inspection methods often rely on manual inspection, which suffers from low efficiency and difficulty in ensuring quality. To address this, those skilled in the art have developed inspection equipment. For example, Chinese Patent Publication No. CN213633213U discloses a lighting device for detecting tile surface defects. This device includes a bridge frame, a lighting mechanism movably mounted on the bridge frame, an arc-shaped bridge, and mounting seats welded to both ends of the arc-shaped bridge for fixing it to a tile conveyor. The lighting mechanism includes a movable frame fitted with the arc-shaped bridge and capable of sliding on it, and a detection spotlight fixed to the lower end of the movable frame by screws. This invention, through the bridge frame and lighting mechanism, utilizes the arc-shaped bridge to flexibly adjust the light angle of the lighting mechanism to detect color differences in the tiles and clearly visualize defects produced after glazing. However, its drawback is that it is limited to detecting color difference, and other glaze defects are difficult to detect. It is necessary to further improve its structure. Summary of the Invention

[0003] The purpose of this invention is to provide a stable, reliable, and easy-to-operate visual inspection device for ceramic tile glaze defects, capable of detecting surface and body defects in ceramic tile blanks, in order to overcome the shortcomings of existing technologies.

[0004] The present invention achieves the above-mentioned objective by adopting the following technical solution: a visual inspection device for defects in glazing of ceramic tiles, characterized in that it includes a frame and a ceramic tile conveying device, a visual defect inspection device, and a defective tile delivery device mounted on it.

[0005] The visual defect detection device includes a light shield assembly, a light source assembly, a vision inspection assembly, and an electrical cabinet assembly. The light source assembly is located outside the ceramic tile conveying device, and the vision inspection assembly is located above the ceramic tile conveying device. It takes pictures according to the settings to obtain image information of the ceramic tile surface. The electrical cabinet assembly contains a main controller connected to the vision inspection assembly, which is used to receive and process the image data collected by the vision inspection assembly. The main controller is connected to a display, which can display the surface status of the ceramic tile in real time, facilitating monitoring and analysis by operators.

[0006] The defective brick delivery device is connected to the ceramic brick conveying device. The defective brick delivery device includes a defective brick delivery bracket, a pressure cylinder lifting assembly, and a defective brick conveying component. The defective brick conveying component is set on the defective brick delivery bracket. The pressure cylinder lifting assembly is connected to the defective brick delivery bracket. The lifting action is triggered by the main controller to separate the defective brick.

[0007] As a further explanation of the above solution, the light shield assembly includes an upper light shield and a connecting frame, a connecting block, and a camera mounting bracket disposed therein. The camera mounting bracket is connected to the connecting frame via the connecting block.

[0008] Furthermore, the upper sunshade includes a sunshade frame and a cover plate, side plates, and door panels installed on it. The cover plate is located at the top of the sunshade frame, and reinforcing ribs are provided at the bottom of the cover plate to improve the strength of the upper sunshade.

[0009] Furthermore, the ceramic tile conveying device and the defective tile conveying component have the same structure, both using conveying rollers to convey ceramic tiles. The defective tile conveying component includes a defective tile conveying motor device, a defective tile motor shaft, and multiple defective tile conveying rollers. The multiple defective tile conveying rollers are parallel to the defective tile motor shaft, and a synchronous belt pulley transmission mechanism connects the defective tile motor shaft and the defective tile conveying rollers to achieve stable conveying of ceramic tiles.

[0010] Furthermore, the synchronous belt pulley transmission mechanism includes a drive pulley, a large synchronous pulley fixed to the end of the defective brick conveying roller, a small synchronous pulley disposed between the two adjacent large synchronous pulleys, and a synchronous belt. The drive pulley is disposed on the defective brick motor shaft, and the synchronous belt is wound around the drive pulley, the large synchronous pulley, and the small synchronous belt.

[0011] Furthermore, the synchronous belt pulley transmission mechanism is equipped with a tensioning pulley component, which includes a tensioning pulley fixing seat, a tensioning pulley shaft, a ball bearing, and a driven pulley. The driven pulley is sleeved on the ball bearing, which is mounted on the tensioning pulley shaft. The tensioning pulley shaft is fixed to the tensioning pulley fixing seat. The tensioning pulley fixing seat is provided with an adjustment slot and corresponding adjustment screws. The tensioning pulley fixing seat is connected and fixed to the defect brick delivery bracket through the adjustment screws to ensure the tension of the synchronous belt and ensure the transmission effect.

[0012] Furthermore, the pressure cylinder lifting assembly includes a pressure cylinder mounting base and a lifting pressure cylinder mounted thereon, with the lifting pressure cylinder vertically positioned below the defective brick delivery bracket.

[0013] Furthermore, the pressure cylinder mounting base includes a rectangular frame welded from several square tubes, and a mounting plate is provided on the rectangular frame for fixing the pressure cylinder, ensuring the stable installation and reliable operation of the lifting pressure cylinder; when a defective brick is detected, the lifting pressure cylinder operates, lifting the defective brick out of the support, so that the defective brick conveying component docks with the ceramic brick conveying device, thereby conveying the defective brick out.

The defective brick conveying motor drives the synchronous belt, which in turn drives the defective brick conveying rollers to rotate, thus conveying the defective brick out.

[0039] Compared with existing technologies, this invention employs a visual inspection structure for ceramic tile glaze defects, primarily composed of a ceramic tile conveying device, a visual defect detection device, and a defective tile delivery device.
