Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of silica gel coating, and particularly relates to a cylindrical thin-walled body automatic silica gel coating device and method. BACKGROUND

[0002] In the field of industrial production, coating a specific solid material surface with a liquid substance (such as silica gel) is a key process, and the coating quality, especially the adhesion and uniformity of the liquid on the solid material, directly determines the performance and pass rate of the final product. Due to the particularity of the structure of cylindrical thin-walled bodies (such as various cylindrical containers and tubular devices), the uniformity, adhesion strength and glue layer density of the inner and outer walls are crucial to the key indicators such as the sealing and durability of the product. However, at present, such processes mainly rely on manual operation, which has significant inconvenience and production problems: manual coating cannot guarantee the uniformity of the glue layer thickness, which easily leads to uneven coverage of the inner and outer walls, affecting product consistency; for deep-diameter ratio large cylinder inner walls or narrow curved surface areas, manual operation is difficult to achieve effective and complete coverage; the operation efficiency is low, and only single-sided coating can be performed at a time, the process is complicated, and the production capacity is limited; at the same time, the control of the glue output is inaccurate due to human factors, which not only causes glue waste, but also makes the product failure rate high.

[0003] Although existing automatic coating equipment has been applied in planar or regular curved surface coating, it still lacks efficient and reliable solutions to meet the coating needs of cylindrical thin-walled bodies, especially to achieve synchronous and precise glue coating of the inner and outer walls. The existing technology cannot simultaneously solve the problems of coating uniformity, coverage ability of deep cavity or narrow area, precise dynamic adjustment of glue output, and efficiency improvement of inner and outer wall simultaneous operation.

A method for automatically coating a cylindrical thin-walled object with silicone, characterized in that: The automatic silicone coating device according to any one of claims 1 to 8 is used, comprising: The workpiece to be processed is placed on the material rotating mechanism (2), and the grating safety system is activated; The controller controls the material pressing mechanism (5) to press the workpiece downward; The controller controls the inner ring gluing mechanism (3) and the outer ring gluing mechanism (4) to move to the workpiece to be processed, and the glue supply mechanism (6) is started; The inner ring gluing mechanism (3) and the outer ring gluing mechanism (4) discharge glue at a constant speed, and the material rotating mechanism (2) drives the workpiece to be processed to rotate. After rotating 360°, the material rotating mechanism stops rotating, the coating process is completed, and the grating safety system (7) is paused.

10. The method for automatically coating cylindrical thin-walled objects with silicone according to claim 9, characterized in that: The material rotating mechanism (2) includes a base (2-1), a rotating platform (2-2), a position detector (2-3) and a rotating motor (2-4). The material rotating mechanism (2) drives the workpiece to be processed to rotate. After rotating 360°, the material rotating mechanism stops rotating. Specifically: The rotating motor (2-4) drives the rotating platform (2-2) to rotate, thereby driving the workpiece to be processed on the base (2-1) to rotate. After the workpiece rotates 360 degrees, the position detector (2-3) transmits information to the controller, and the controller controls the rotating motor (2-4) to stop rotating.
