Description

Technical Field

[0001] This utility model relates to the processing of carbon fiber preforms, specifically to an intelligent needle punching device for carbon fiber container preforms. Background Technology

[0002] The needle-punching process for carbon fiber preforms used in traditional polycrystalline and monocrystalline silicon liquid containment tubes or crucibles is done manually. Even when a motor is used to drive a row of needles through a linkage mechanism to needle the surface of the preform bit by bit, the position of the preform relative to the needles changes, requiring constant manual adjustment. Because the air at the work site contains a large amount of carbon fiber dust, although wearing masks can reduce inhalation, this dust can cause itching when it settles on the skin, and in severe cases, allergies or shock. Currently, it is extremely difficult to recruit operators for this position. Utility Model Content

[0003] In view of the above problems, this utility model provides an intelligent needle punching device for carbon fiber container preforms.

[0004] The technical solution of this utility model:

[0005] A smart needle punching device for carbon fiber container preforms includes a carbon fiber preform needle punching wooden mold, a robot, and several needles, with the needles mounted on a connecting plate of the robot; the carbon fiber container preform is placed on the carbon fiber preform needle punching wooden mold and needled by the robot.

[0006] A smart needle-punching device for carbon fiber container preforms includes a carbon fiber preform needle-punching wooden mold, a robot, and a carbon cloth needle-punching balance wheel assembly. The carbon cloth needle-punching balance wheel assembly is mounted on a connecting plate of the robot. The carbon fiber container preform is placed on the carbon fiber preform needle-punching wooden mold and needle-punched by the robot. The carbon cloth needle-punching balance wheel assembly includes a balance wheel support, a balance wheel rotation main shaft, a balance wheel, several balance wheel reciprocating rods, a drive structure, and several needles. The balance wheel rotation main shaft is mounted on the balance wheel support, and the balance wheel is disposed within the balance wheel support, which contains an eccentric balance wheel shaft. The eccentric balance wheel shaft is connected to the balance wheel rotation main shaft. The eccentric balance wheel shaft is rotatably connected to the balance wheel. Each balance wheel reciprocating rod is mounted side-by-side on the balance wheel support and connected to the balance wheel via several balance wheel drive rods. One end of each balance wheel drive rod is movably connected to the balance wheel, and the other end is movably connected to the balance wheel reciprocating rod. The drive structure is connected to the balance wheel rotation main shaft, and each needle is mounted on each balance wheel reciprocating rod. The drive structure drives the balance wheel rotation main shaft to rotate, and the rotation of the balance wheel rotation main shaft drives the balance wheel to oscillate via the eccentric balance wheel shaft. The oscillation of the balance wheel drives each balance wheel reciprocating rod to move repeatedly in sequence via each balance wheel drive rod, and each needle moves repeatedly in sequence along with each balance wheel reciprocating rod.

[0007] Further refining the above technical solution, there are two carbon cloth needle-punched balance wheel assemblies, which are symmetrical and whose main rotation axes rotate in the same direction and synchronously. Thus, at the same time, the needles of one carbon cloth needle-punched balance wheel assembly move upwards, while the needles of the other carbon cloth needle-punched balance wheel assembly move downwards, exhibiting a Fourier reciprocating motion, resulting in zero additional force (vertical impact) on the robot's end effector.

[0008] To further refine the above technical solution, the two carbon cloth needle-punched balance wheel assemblies share a common drive structure; the drive structure consists of a motor connected to a driving gear and two driven gears, with the two driven gears respectively mounted on the swing rotation main shafts of the two carbon cloth needle-punched balance wheel assemblies.

[0009] Further refining the above technical solution, the intelligent needle-punching device also includes a fixed table frame, a rotating fixed disk, and a drive mechanism. The rotating fixed disk is mounted on the fixed table frame, and the drive mechanism is connected to the rotating fixed disk. The carbon fiber preform needle-punching mold is mounted on the rotating fixed disk, and the robot is mounted on one side of the fixed table frame. During needle-punching, the drive mechanism drives the rotating fixed disk to rotate, and the carbon fiber preform needle-punching mold rotates together with the rotating fixed disk. The carbon fiber container preform rotates together with the carbon fiber preform needle-punching mold. The robot only needs to perform curved motion on a single upper and lower axis to ensure rapid and uniform needle-punching of the entire preform surface in the perpendicular normal direction, thereby improving efficiency and ensuring quality.

[0010] To further refine the above technical solution, the drive mechanism is composed of a motor connected to a main synchronous pulley, a driven synchronous pulley, and a synchronous pulley, wherein the driven synchronous pulley is coaxial with the rotating fixed disk.

[0011] The advantages of this invention are that it has a reasonable design, simple structure, and can realize automated needle punching of carbon fiber preforms. Attached Figure Description

Specifically, the drive structure 6-4 drives the main shaft 6-2 of the pendulum wheel to rotate. The rotation of the main shaft 6-2 of the pendulum wheel drives the pendulum wheel 6-3 to swing through the eccentric pendulum wheel shaft 6-7.
