[0013] This utility model has the following beneficial effects:

[0014] 1. The automatic silicone burr removal device provided by this utility model, through the design of positioning components, toothed rings, and removal blades, allows for the placement of the silicone ring pad to be burred on the surface of the worktable during use. The positioning components fix the silicone ring pad, and the positioning range can be adjusted according to its size to ensure the accuracy and stability of the positioning, providing reliable stability for subsequent burr removal. Then, by starting the drive motor, its output shaft drives the gear to rotate. The gear meshes with the toothed ring around the turntable, causing the turntable to rotate around the worktable. The fixing plate on the turntable rotates accordingly, and the electric push rod on the fixing plate pushes the removal blade to extend. At the same time, the guide rod provides guidance for the removal blade. As the turntable rotates, the removal blade passes over the edge of the silicone ring pad, which can evenly and thoroughly remove the burrs, improving product quality. In addition, the design of the ring groove and ring block can effectively reduce the wear between the turntable and the worktable during rotation, thus making it suitable for products of various sizes and shapes, increasing the applicability of the device, and providing good burr removal effect.

[0015] 2. The automatic silicone burr removal device provided by this utility model, through the design of a visual positioning sensor, controller, linear cylinder, and cross frame plate, uses a visual positioning sensor to detect the outer diameter of the silicone ring, and the controller calculates and drives the linear cylinder to make four sliding blocks move radially synchronously along the sliding groove of the cross frame plate, dynamically adjusting the pressing position of the lower pressure rod. This allows it to adapt to silicone rings of different sizes without the need for manual shape change, reducing the time required for shape change and improving work efficiency. In addition, the hydraulic cylinder drives the fixed plate to descend, so that the soft rubber block installed on the lower surface of the lower pressure rod can be tightly attached to its surface, achieving flexible and stable clamping, avoiding the indentation or damage that traditional fixing methods may cause to silicone products.
