They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] like Figures 1 to 7 A preferred embodiment of the thermoplastic composite component laying device shown includes a motion system and a laying execution mechanism 300. The laying execution mechanism 300 includes a tension unwinding mechanism, a rolling mechanism, and a heater 316.

[0040] The motion system includes a translation mechanism 100 and a rotation mechanism 200. The translation mechanism 100 provides the laying actuator with three degrees of translation freedom, and the rotation mechanism 200 provides the laying actuator with a degree of rotation freedom about the Z-axis.

[0041] The translation mechanism 100 includes a fixed platform 101, a moving platform 102, a translation guide rail 103, a parallelogram linkage mechanism 104, and a translation drive mechanism 105. In this embodiment, the translation guide rail 103, the parallelogram linkage mechanism 104, and the translation drive mechanism 105 are provided in at least three sets.

[0042] The fixed platform 101 has a triangular structure. The translation guide rail 103 and the translation drive mechanism 105 are respectively installed at the three corners of the fixed platform 101, and the fixed platform 101 is fixed to the external frame. In this embodiment, the translation drive mechanism 105 is preferably a motor. The motor is connected to a translation lead screw 107. Each set of parallelogram linkage mechanisms 104 is slidably engaged with the translation guide rail 103 through a translation slider 106. The translation lead screw 107 is threadedly connected to the translation slider 106. The translation drive mechanism 105 drives the translation lead screw 107 to rotate, thereby driving the parallelogram linkage mechanism 104 to move along the translation guide rail 103 through the translation slider 106.

[0043] Each parallelogram linkage mechanism 104 is formed by four linkage members, specifically, the four linkage members are long side rod one 1041, long side rod two 1042, short side rod one 1043 and short side rod two 1044, both ends of the long side rod one 1041 and the long side rod two 1042 are rotatably connected with the rotating shaft 1045, the rotating shaft 1045 is perpendicularly connected with both ends of the two short side rods, the short side rod one 1043 on the upper side is rotatably connected with the connecting seat one 108 arranged on the translation slide 106, and the other short side rod two 1044 is rotatably connected with the connecting seat two 109 arranged on the moving platform 102.

[0044] The moving platform 102 is provided with a mounting port 1021, and the laying execution mechanism is mounted on the mounting port 1021 of the moving platform 102.

[0045] The translation driving mechanism 105 drives the parallelogram linkage mechanism 104 to move along the translation guide rail 103, and the parallelogram linkage mechanism 105 drives the moving platform 102 to move in the process, so that the moving platform 102 can move in three degrees of freedom under the condition of keeping parallel with the fixed platform 101, so that the laying execution mechanism mounted on the moving platform 102 can move in the up-down direction, the left-right direction and the front-back direction.

[0046] Since the translation mechanism 100 can only generate three translation movements and has no rotation freedom, in order to realize multi-directional laying, a rotation freedom around the Z axis is needed, which is realized by the rotation mechanism 200; the rotation mechanism 200 includes a rotation motor 201 and a synchronous belt transmission mechanism 202, and the rotation motor 201 drives the laying execution mechanism to rotate around the Z axis relative to the moving platform 102 through the synchronous belt transmission mechanism 202.

[0047] The laying execution mechanism 300 is connected to the mounting port 1021 of the moving platform 102 through the cooperation of the support plate 301 and the bearing 302; specifically, the support plate 301 is mounted on the mounting port 1021 of the moving platform 102, the bearing 302 is mounted in the mounting hole of the support plate 301, and the laying execution mechanism 300 is mounted on the bearing 302. The laying execution mechanism 300 includes a tension unwinding mechanism and a roller pressing mechanism; the tension unwinding mechanism lays the thermoplastic pre-impregnated fiber bundle 500 according to a certain guide, and the roller pressing mechanism rolls and consolidates the laid thermoplastic pre-impregnated fiber bundle.

[0048] Specifically, the tension unwinding mechanism comprises a reel 303 on which the thermoplastic prepreg tows 500 are wound, an unwinding motor 304, a feeding motor 305 located below the reel 303 and the unwinding motor 304, a conveying wheel 306, and a compression wheel 307 in compression fit with the conveying wheel 306. The reel 303 and the unwinding motor 304 are in two groups, the unwinding motor 304 is fixed on an unwinding frame 308, and the feeding motor 305 is fixed on a feeding frame 309 below the unwinding frame 308. A plurality of guide wheels 310 and a plurality of deflection rollers 311 are arranged between the unwinding motor 304 and the feeding motor 305, the output thermoplastic prepreg tows 500 pass through the guide wheels 310 and the deflection rollers 311, and an included angle is formed at the guide wheels and the deflection rollers; a tension sensor 312 is further arranged at a guide wheel 310 located at an intermediate position of the plurality of guide wheels, and the tension sensor 312 can measure the force currently acting on the thermoplastic prepreg tows 500 in real time. The compression wheel 307 is installed on a compression plate 313 located on one side of the feeding frame 309, one end of the compression plate 313 is connected with the feeding frame 309 through a connecting shaft, the compression plate 313 can rotate around the connecting shaft, and a bolt and a spring are installed at the other end of the compression plate 313, the spring is compressed against the compression plate 313 by adjusting the bolt, and then the compression wheel 307 is tightly attached to the conveying wheel 306. When the tows are installed or replaced, the compression plate 313 can be loosened, so that there is a large gap between the compression wheel 307 and the conveying wheel 306 to facilitate the installation of the tows. The unwinding motor 304 drives the reel 303 to rotate in the direction opposite to the winding direction of the thermoplastic prepreg tows, so as to tighten the thermoplastic prepreg tows 500, the feeding motor 305 drives the conveying wheel 306 to rotate, and the conveying wheel 306 and the compression wheel 307 are in compression fit, so that the thermoplastic prepreg tows 500 form a tension. In the laying execution mechanism, a merging block 314 is further arranged below the reel 303, the merging block 314 is provided with a merging slot penetrating therethrough; two groups of the reel 303 output two thermoplastic prepreg tows 500, the two thermoplastic prepreg tows 500 pass through the guide wheels 310 respectively, then pass through the merging slot of the merging block 314, and are arranged side by side into one tow, and the merged tows are sequentially deflected by the deflection rollers 311 and then output by the friction driving action formed between the conveying wheel 306 and the compression wheel 307. The output side of the conveying wheel 306 is provided with a tow guide plate 315, the tow guide plate 315 has a guide slot penetrating therethrough, and the thermoplastic prepreg tows 500 output by the friction driving are output to a workbench matched with the laying device through the guide slot of the tow guide plate 315. The tow guide plate 315 can make the output tows tightly adhere to each other, and can limit the left and right movement of the tows to accurately reach the designated position. The tow guide plate 315 is provided with two grooves 3151 on both sides, a heater 316 and a shearing mechanism are arranged at positions corresponding to the two grooves respectively, the heater 316 heats the output thermoplastic prepreg to soften the thermoplastic prepreg to a degree of fusion.The shearing mechanism includes a shearing drive 317 and a shearing blade 318. In this embodiment, the shearing drive 317 is a shearing cylinder, which can drive the shearing blade 318 to extend into the filament guide plate 315 through the slot 3151 to cut the output thermoplastic prepreg filaments.

[0049] The roller pressing mechanism is mounted on the feeding frame 309. The roller pressing mechanism includes a roller pressing drive 319, a pressure roller 320, a bonding drive 321, and a bonding block 322. The roller pressing drive 319 and the pressure roller 320 are located near the heater 316 and the filament guide plate 315. The roller pressing drive 319 drives the pressure roller 320 to press the thermoplastic prepreg filaments onto the worktable 400 that cooperates with the laying device. The pressure roller 320 is made of a soft material to increase the contact area with the filaments, and air is circulated within it to lower the temperature and prevent damage during prolonged operation. The bonding drive 321 drives the bonding block 322 to press down onto the thermoplastic prepreg filaments on the worktable, maintaining pressure between the filaments for a certain period to achieve complete bonding. In this embodiment, both the roller pressing drive 319 and the bonding drive 321 are cylinders.

[0050] In general, the translation mechanism 100 drives the laying execution mechanism 300 to perform translational motion in three degrees of freedom. The rotary motor 201 in the rotation mechanism 200 drives the bearing to rotate through the synchronous belt transmission mechanism 202, so that the laying execution mechanism 300 rotates about the Z-axis relative to the moving platform 102. The rotation mechanism 200 and the translation mechanism 100 cooperate to drive the laying execution mechanism 300 to perform multi-directional thermoplastic prepreg filament laying and forming.

[0051] The thermoplastic composite material component laying device of this invention can be applied to the production line of thermoplastic composite products, such as... Figure 9 As shown, the thermoplastic composite product production line includes a laying work area 700, a welding work area 800, and an inspection work area 900 arranged sequentially from left to right. The thermoplastic composite component laying device of this utility model is set in the laying work area. The laying work area is used to lay the molded thermoplastic composite components on the workbench of the production line. The welding work area is used to weld the parts to be welded onto the thermoplastic composite components to obtain thermoplastic composite products. The inspection work area is used for laying inspection and welding inspection.

[0052] by Figure 8 The working principle of the thermoplastic composite material component laying device of this utility model is illustrated using the thermoplastic composite material component shown as an example, as follows:

[0053] Two reels 303, each wound with thermoplastic prepreg filaments 500, are mounted onto the unwinding frame 308 of the laying actuator 300. The thermoplastic prepreg filaments 500 on the two reels 303 are wound downwards around the guide wheel 310, through the merging block 314 to form a parallel filament bundle, then around the guide roller 311, changing direction, and passing between the conveyor wheel 306 and the clamping wheel 307. The spring presses the pressure plate 313 by adjusting the bolts, so that the clamping wheel 307 mounted on the pressure plate 313 is in close contact with the conveyor wheel 306. The unwinding motor 304 drives the reels 303 to rotate in the opposite direction to the winding direction of the thermoplastic prepreg filaments, tautning the thermoplastic prepreg filaments 500. The feeding motor 309 drives the conveyor wheel 306 to rotate, and the conveyor wheel 306 and the clamping wheel 307 are pressed together, creating tension in the thermoplastic prepreg filaments 500. The feeding motor 305 continuously drives the conveyor wheel 306 to rotate, and the combined filament bundle is output through the frictional drive between the conveyor wheel 306 and the pressing wheel 307. The output filament bundle enters the filament bundle guide plate 315, and the heater 316 heats the filament bundle, softening the thermoplastic prepreg filament bundle to a molten state. The heated thermoplastic prepreg filament bundle is guided by the filament bundle guide plate 315 to the worktable 400 that cooperates with the laying device of this utility model. The roller pressing drive 319 drives the pressure roller 320 to press the thermoplastic prepreg filament bundle onto the worktable 400, and the consolidation drive 321 drives the consolidation block 322 to press down on the thermoplastic prepreg filament bundle on the worktable and maintains the pressure for a certain period of time to completely solidify the laid filament bundle. After completing one laying operation, such as laying a row or column of filaments, the shearing drive 317 drives the shearing blade 318 to extend into the filament guide plate 315 through the slot 3151 to cut the output thermoplastic prepreg filaments. During shearing, since the shearing blade 318 is a certain distance away from the contact point between the pressure roller 320 and the worktable 400, the filaments are cut in advance before the end of each laying operation, so that the filaments can reach the predetermined laying position. That is, the shearing point is cut when it reaches a certain distance from the predetermined laying end (this distance is the distance between the shearing point and the roller pressure point). The translation drive mechanism 105 in the translation mechanism 100 drives the parallelogram linkage mechanism 104 to move along the translation guide rail 103. During this movement, the parallelogram linkage mechanism 105 links with the moving platform 102, enabling the moving platform 102 to perform three degrees of freedom translation while remaining parallel to the fixed platform 101. This allows the laying execution mechanism 300 mounted on the moving platform 102 to perform vertical, horizontal, and forward / backward translations. The rotary motor 201 in the rotation mechanism 200 drives the laying execution mechanism 300 to rotate around the Z-axis relative to the moving platform 102 via a synchronous belt drive mechanism 202. Thus, driven by the motion system, the laying execution mechanism 300 performs multi-degree-of-freedom spatial motion, continuously laying the thermoplastic prepreg filaments 500 in multiple directions according to the aforementioned filament laying and forming process, ultimately obtaining… Figure 8The thermoplastic composite component 600 is shown.
