Description

Technical Field

[0001] This utility model relates to the field of thermoplastic prepreg production technology, specifically to a laser in-situ consolidation and laying equipment for thermoplastic prepreg. Background Technology

[0002] Continuous fiber reinforced thermoplastic composites, as advanced representative materials characterized by their lightweight, high strength, and corrosion resistance, have become one of the preferred materials in the aerospace equipment manufacturing field. Currently, widely used composite component manufacturing processes include compression molding, vacuum bag molding, resin injection molding, and automated layup in-situ curing. Among these, automated layup in-situ curing is favored due to its high manufacturing efficiency and wide range of applicable parts.

[0003] Chinese Patent Publication No. CN116001316A discloses an automatic laying device for thermoplastic composite prepreg tape with adjustable laser heating angle. The device includes a base plate, on which are mounted a belt roller, a guiding module, a tension control module, a refeeding module, a clamping and shearing module, a rolling module, a heating module, and a cooling module. The tension control module is positioned between the belt roller and the refeeding module. The refeeding module is positioned at the inlet of the guiding module, the rolling module is positioned at the outlet of the guiding module, and the clamping and shearing module is positioned in the middle of the guiding module for heating the thermoplastic composite prepreg tape. The heating module and the cooling module are positioned opposite each other on the bottom sides of the rolling module. This invention allows for adjustment of the laser heating angle. By studying the influence of the laser angle on the forming quality of the thermoplastic composite prepreg tape and its heating mechanism, the laser heating efficiency of the thermoplastic prepreg tape can be maximized.

[0004] When the laying device of the aforementioned patent extrudes the material from the feed head and lays it on the material plate, there may be floating dust in the air. The dust will stick between the two materials, resulting in gaps between the two materials and poor material adhesion. Utility Model Content

[0005] The purpose of this invention is to provide a laser in-situ consolidation and laying equipment for thermoplastic prepregs. By setting a connecting rod on the second connecting block, and setting a suction fan on the end of the connecting rod away from the second connecting block, and setting rubber pads around the suction fan, the connecting rod is located on both sides of the nozzle. When the nozzle sprays material, the suction fan starts to work to discharge the dust in front of the nozzle to both sides, and the rubber pads can also stick some dust to prevent dust from flying around, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser in-situ consolidation and laying equipment for thermoplastic prepreg, comprising a second connecting block, a nozzle base being provided at one end of the second connecting block, a nozzle being provided on the nozzle base, and a connecting rod being provided on the second connecting block, the connecting rod being located on both sides of the nozzle, a suction fan being provided at the end of the connecting rod away from the second connecting block, a material conveying pipe being provided on the second connecting block, a material pump being provided in the middle section of the material conveying pipe, a hopper being provided at the end of the material conveying pipe away from the second connecting block, and a feed pipe being provided at the upper end of the hopper.

[0007] Preferably, the connecting rod is provided with a rubber pad around the suction fan, and the rubber pad is bonded to the connecting rod.

[0008] Preferably, the second connecting block has a second fixing block at the end away from the nozzle.

[0009] Preferably, a damping rotation shaft is provided on one side of the second fixing block, and the damping rotation shaft is bolted to the second fixing block.

[0010] Preferably, the damping rotation shaft has a first fixing block on the side away from the second fixing block.

[0011] Preferably, the first fixing block is provided with a first connecting block, and the first connecting block and the first fixing block are integrally formed.

[0012] Preferably, the first connecting block has a first connecting flange at the end away from the first fixed block.

[0013] Preferably, the first connecting flange has an insertion hole.

[0014] Preferably, the feed pipe is provided with a second connecting flange at the end away from the hopper.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features a connecting rod mounted on a second connecting block, with a suction fan mounted on the end of the connecting rod furthest from the second connecting block. Rubber pads are placed around the suction fan on the connecting rod, which is located on both sides of the nozzle. When material is ejected from the nozzle, the suction fan operates to expel dust in front of the nozzle to both sides. The rubber pads also trap some dust, preventing it from scattering. This effectively avoids the problem in existing laying devices where floating dust may exist in the air when material is extruded from the feed head and laid on the material plate. Dust can adhere between two pieces of material, causing gaps and poor material adhesion. Attached Figure Description
