Technical Field

[0001] This invention relates to the field of spiral tiling technology, specifically to a spiral tiling apparatus. Background Technology

[0002] Spiral lay-up equipment is an automated device used for molding composite material components. It mainly lays prepreg on the mold surface by spiral winding to form components with specific mechanical properties.

[0007] Preferably, the rotating screen is located on the left side of the mold body, and the right side of the rotating screen is in close contact with the left side of the mold body. The rotating screen can be used to flatten the material sheet on the surface of the mold body, so that the material sheet can cover the surface of the mold body.

[0008] Preferably, the mobile paving mechanism includes a mobile ground rail, which is disposed at the top back end of the horizontal ground. The bottom of the mobile ground rail is in contact with the top of the horizontal ground. The mobile ground rail is disposed at the back end of the fixed platform. A six-axis robot is slidably connected to the top left side of the mobile ground rail. A first needle-piercing end effector is fixedly connected to the front of the six-axis robot. An end effector adjustment plate is disposed on the top of the first needle-piercing end effector.

[0009] Preferably, the bottom of the movable ground rail is in contact with the top of the horizontal ground, and the front of the movable ground rail is in contact with the back of the fixed platform. The movable ground rail enables the six-axis robot to move left and right.

[0014] Compared with the prior art, the present invention provides a spiral laying device, which has the following beneficial effects:

[0015] 1. In this spiral laying device, the first needle-piercing end effector at the tail end of the six-axis robot first releases the material sheet and lays it on the mold body, while simultaneously inserting the rubber strip into the groove on the mold body. The cylinder drives the fixing structure to rotate inside the fixing frame, controlling the material sheet on the mold. The external motor drives the rotating structure to rotate the entire mold. The first needle-piercing end effector releases in sequence, and the rotating structure cooperates to lay all the material sheet on the mold body. The material sheet at the front end covers the material sheet at the tail end. The external motor pushes the rotating roller to fit with the mold body, rolling the material sheet evenly and completely laying it on the mold body.

[0016] 2. The spiral laying device picks up the prepreg fabric that is fixed together from the workbench and moves it to the laying station. The six-axis robot moves the end effector adjustment plate close to the conical surface of the mold. The first needle-punched end effector is released in sequence to lay the fabric on the mold body. The position of the first needle-punched end effector can be adjusted according to the process requirements through the slide on the end effector adjustment plate to achieve the switching of different sized sheets.

[0017] 3. In this spiral laying device, the rubber strip is used to assist in fixing multiple prepreg fabrics together and positioning them on the mold body. It is placed into two arc-shaped grooves on the worktable by the unwinding mechanism. Multiple rotating structures are equipped on both sides of the grooves to transport the rubber strips inward. The prepreg fabric is picked up by the second needle-punched end pick-up device on the truss and placed between the two rubber strips in a fan shape.

[0018] 4. The spiral laying device has a fiber rod implantation and fixing mechanism and multiple second needle-punched end picks installed on the moving platform. The second needle-punched end picks are used to grab the prepreg fabric and transfer it through the moving platform. The fiber rod implantation and fixing mechanism implants the fiber rods into the rubber strips and connects and fixes them together. The fiber rods are supplied by the unwinder on the moving platform and are cut on both sides to connect and fix the fabric to the rubber strips and to each other.

[0019] 5. In this spiral laying device, the prepreg roll is fed into the cutting conveyor by the unwinding frame and conveyed backward. The cutting blade moves to the origin and cuts the fabric into the required dimensions. The cut fabric is picked up by the end picker and placed on the worktable. Excess fabric is conveyed to the waste bin. Attached Figure Description
