Description

Technical Field

[0001] The invention belongs to the technical field of film material pasting, and in particular relates to a carbon fiber composite material pasting device. Background Art

[0002] Prepreg is a resin matrix / reinforcement material combination made by impregnating continuous fibers, fabrics and chopped fibers with a resin matrix under certain conditions. It is a material form for manufacturing advanced composite components.

[0003] Thermosetting resins cure through chemical reactions at high temperatures, converting prepregs into high-performance solid structural materials, also known as thermosetting resin-based composite materials. This material is lightweight, high-strength, durable, high-temperature resistant, and has good rigidity.

[0004] Thermosetting prepreg carbon fiber laying requires peeling the carbon fiber from the release paper, leaving the carbon fiber laid on the surface of the workpiece.

[0005] In the related technology, a release paper is adhered to one side of the carbon fiber prepreg, and the carbon fiber prepreg with the release paper is wound on a material tray; then the material tray is installed on a laying device, the carbon fiber prepreg is released from the material tray, and a rubber roller presses the carbon fiber prepreg on the surface of the workpiece. The carbon fiber prepreg is laid on the surface of the workpiece by moving the workpiece or moving the laying device. Two motors perform the work of receiving and feeding respectively. The discharge motor drives the material tray to feed the material, and the release paper is tightened on the receiving tray for recycling. In the current technology, when the two motors work separately, there will be errors in the work of receiving and feeding, and the precision is low. At the same time, the loss rate of the motor is high, and the maintenance cost is high. Summary of the invention

[0006] In view of this, in order to solve the problem of low precision of existing carbon fiber laying, the present invention proposes a thermosetting prepreg carbon fiber laying device.

[0007] To achieve the above object, the present invention adopts the following technical scheme: a thermosetting prepreg carbon fiber paving device, comprising a mounting plate, a synchronous wheel assembly, a robot connection assembly and a paving assembly; the synchronous wheel assembly is fixed on the back of the mounting plate, and the robot connection assembly and the paving assembly are fixed on the front;

[0008] The synchronous wheel assembly includes a material discharging synchronous wheel, a material receiving shaft, a material receiving synchronous wheel and a hinge screw. The material discharging synchronous wheel and the material receiving synchronous wheel are belt-matched to drive each other. The material receiving synchronous wheel and the material receiving shaft are coaxially matched and installed on the mounting plate. The material discharging synchronous wheel is fixed on the mounting plate by a hinge screw.

[0009] The robot connection assembly includes a robot connection piece, a nozzle connection piece and a rib plate, wherein the rib plate is fixed to the mounting plate by screws, the nozzle connection piece is mounted on the rib plate, and the robot connection piece is mounted on the nozzle connection piece and coaxially matched;

[0010] The paving assembly includes a locking head, a material receiving baffle, a material tray, a material pressing cylinder, a cutting cylinder, a roller head and a clamping cylinder. The locking head and the material receiving baffle are fixed to the mounting plate through a material receiving shaft. The locking head and the material receiving baffle are coaxially matched. The material tray is fixed to the mounting plate through a hinged screw and locked with a nut. The material tray and the hinged screw are coaxially matched. The material pressing cylinder, the cutting cylinder, the roller head and the clamping cylinder are fixed to the mounting plate through screws. A carbon fiber material paving path is formed between the material tray, the roller head and the material receiving shaft, and the material tray is arranged relative to the roller head.

[0011] Furthermore, the robot is mounted on a robot connector and moves and lays the tiles through the robot connector.

[0012] Furthermore, the carbon fiber material adopts unidirectional thermosetting prepreg carbon fiber, which is fixed on the material tray. When the equipment is paving, the carbon fiber prepreg is discharged from the material tray by the unloading synchronous wheel. At the same time, the collecting synchronous wheel moves to separate the prepreg into protective film and carbon fiber.

[0013] Furthermore, the carbon fiber is driven by a compacting cylinder to be laid, and the protective film is recovered by a receiving shaft and recovered on a receiving baffle.

[0014] Furthermore, during the paving work, the clamping cylinder is in an open state and the pressing cylinder is working. When the paving is completed, the equipment will cut the carbon fiber. When the equipment is in the cutting state, the clamping cylinder starts working. The clamping cylinder generates force on the carbon fiber, making the carbon fiber in a straight state. In this state, the cutting cylinder gives it a downward shear force to achieve cutting.

[0015] Compared with the prior art, the thermosetting prepreg carbon fiber paving device of the present invention has the following beneficial effects:

[0016] During the movement of the device of the present invention, the synchronous wheel assembly can ensure that material feeding and material collection can be completed together. When paving is performed, the carbon fiber material drives the hinged screw to rotate, the hinged screw is connected to the material tray and rotates, the material discharge synchronous wheel is connected to the material tray and rotates, and the material collection synchronous wheel is driven by the synchronous belt to rotate, so as to realize the integrated work of material collection and feeding, which saves costs, improves the efficiency of material collection and feeding, and reduces subsequent failures and maintenance.
