Description

Technical Field

[0001] This utility model relates to the field of carbon fiber composite material laying technology, and in particular to an auxiliary structure for carbon fiber composite material laying. Background Technology

[0002] Tape laying machines are specialized equipment with relatively high technical content. They automatically lay prepreg tape and cut parts by using a gantry bed structure, a rotatable and lifting support, and a cutting area for the laying area.

[0003] During the unwinding process of carbon fiber prepreg, the carbon fiber prepreg tape on the laying unit needs to be laid onto the adsorption platform. The laying unit is driven by the gantry to move above the adsorption platform. Then, the unwinding assembly drives the tape on the tray to unwind. The traction assembly and the guide assembly work together to guide the tape onto the adsorption platform. The guide assembly is located behind the traction assembly. In order to ensure that the traction assembly can successfully adsorb the tape onto the platform, the guide assembly needs to be adjusted during the traction process to accommodate tapes of different specifications.

[0004] Therefore, this application proposes an auxiliary structure for carbon fiber composite material laying. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary structure for laying carbon fiber composite materials. This structure solves the technical problem in existing technologies where "during the unwinding process of carbon fiber prepreg, the carbon fiber prepreg tape on the laying unit needs to be laid onto the adsorption platform. The laying unit is driven to move above the adsorption platform by a gantry frame, and then the unwinding assembly drives the tape on the tray to unwind. The traction assembly and guiding assembly work together to guide the tape onto the adsorption platform. The guiding assembly is located in front of the traction assembly. To ensure that the traction assembly successfully adsorbs the tape onto the platform, the guiding assembly needs to be adjusted during the traction process to accommodate tapes of different specifications."

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0026] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments:

[0027] Example 1

[0028] refer to Figure 1-2 A carbon fiber composite material laying auxiliary structure includes a mounting frame 8, a front rolling cylinder 9, a mounting plate 11, and a rear rolling cylinder 12. A bearing is fixedly installed inside the side wall of the mounting frame 8. A rotating shaft is fixedly sleeved on the inner ring of the bearing. One end of the rotating shaft is fixedly installed on the side wall of the front rolling cylinder 9. A push plate 10 is fixedly installed on the telescopic end of the front rolling cylinder 9. A fixed plate 2 is rotatably connected to the other end of the push plate 10. A rotating plate 6 is fixedly installed on the lower end of the fixed plate 2. The other end of the rotating plate 6 is rotatably connected to the side wall of the mounting frame 8. A belt pulley 7 is provided on the upper right side of the mounting frame 8.

[0029] From left to right, the side wall of the rotating plate 6 is provided with a front roller 1 and a guide mechanism 23. The front roller 1 is rotatably connected to the side wall at the left end of the rotating plate 6 and is used to roll the carbon fiber composite tape. The guide mechanism 23 is used to guide the tape on the belt pulley 7.

[0030] An adjusting motor 13 is fixedly installed on the side wall of the mounting plate 11. The output end of the adjusting motor 13 passes through the side wall of the mounting plate 11 and is fixedly installed on the side wall of the rear rolling cylinder 12. A wheel frame 21 is fixedly installed on the telescopic end of the rear rolling cylinder 12. A limit slider 14 is fixedly installed on the upper surface of the wheel frame 21. The limit slider 14 is slidably connected to the side wall of the rear rolling cylinder 12. A silicone pressure roller 15 is rotatably connected to the bottom of the wheel frame 21.

[0031] An electric scissor 16 is fixedly installed on the lower side wall of the adjusting motor 13. The cutting end of the electric scissor 16 is located at the left exit of the guide mechanism 23. The electric scissor 16 can cut the tape after the work is completed, which is convenient and quick.

[0032] The rear rolling cylinder 12 has a limit groove on its side wall. The limit slider 14 is fixedly installed with a limit block that matches the limit groove on the side opposite to the rear rolling cylinder 12. The limit block is slidably connected in the limit groove, so that the limit slider 14 can only slide up and down along the side wall of the rear rolling cylinder 12.

[0033] The guide mechanism 23 includes an upper guide plate 4 and a lower guide plate 3. The upper guide plate 4 is located above the lower guide plate 3. A positioning block 22 is fixedly installed on the upper end face of the upper guide plate 4. The positioning block 22 is fixedly installed on the rotating plate 6 by bolts. The lower guide plate 3 is also fixedly installed on the rotating plate 6 by bolts. The guide mechanism 23 also includes a guide wheel 5, which is rotatably connected to the side wall of the rotating plate 6.

[0034] Specifically, when applying the tape, the front rolling cylinder 9 first presses down on the fixed plate 2 through the telescopic end, and the left end of the rotating plate 6 moves down a distance of about 15-20 mm. The rear rolling cylinder 12 presses down on the silicone pressure roller 15 to apply the tape to the end of the tape. Then, the front rolling cylinder 9 retracts the telescopic end to raise the left end of the rotating plate 6, pulling the tape out at an angle of less than 45°. The electric scissors 16 moves the front scissors to the tape position, cuts the tape, and then moves the electric scissors 16 back to its original position. The silicone pressure roller 15 rolls the tape backward.

[0035] Example 2

[0036] refer to Figure 3-5 The difference between Embodiment 2 and Embodiment 1 is that the guide mechanism 23 includes an upper guide plate 4 and a lower guide plate 3. The upper guide plate 4 is fixedly installed on the rotating plate 6 by a positioning block 22. An electric push rod 17 is fixedly installed on the side wall of the upper guide plate 4. A fixing block 18 is fixedly installed on the telescopic end of the electric push rod 17. The fixing block 18 is fixedly installed on the lower guide plate 3. The guide mechanism 23 also includes a guide wheel 5, which is rotatably connected to the side wall of the rotating plate 6.

[0037] Among them, an upper mounting block 19 and a lower mounting block 20 are fixedly installed on the front side walls of the upper guide plate 4 and the lower guide plate 3, respectively, and a telescopic rod is fixedly installed between the upper mounting block 19 and the lower mounting block 20.

[0038] When the guide mechanism 23 needs adjustment, the electric push rod 17 is activated. The electric push rod 17 pushes the fixed block 18 up and down through the telescopic end. The fixed block 18 drives the lower guide plate 3 up and down, completing the adjustment of the distance between the lower guide plate 3 and the upper guide plate 4. The telescopic rod set between the upper mounting block 19 and the lower mounting block 20 allows the lower guide plate 3 to move smoothly, so that tapes of different specifications can pass through.

[0039] Specifically, when applying the tape, the front rolling cylinder 9 first presses down on the fixed plate 2 through the telescopic end, and the left end of the rotating plate 6 moves down a distance of about 15-20 mm. The rear rolling cylinder 12 presses down on the silicone pressure roller 15 to apply the tape to the end of the tape. Then, the front rolling cylinder 9 retracts the telescopic end to raise the left end of the rotating plate 6, pulling the tape out at an angle of less than 45°. The electric scissors 16 moves the front scissors to the tape position, cuts the tape, and then moves the electric scissors 16 back to its original position. The silicone pressure roller 15 rolls the tape backward.
