It should be noted that the first driving member can be a cylinder or a servo motor.

[0025] Furthermore, the cutting and stacking device 200 is located at the rear end of the feeding device 100, and includes a cutting mechanism and a stacking mechanism.

[0026] It can be understood that the cutting mechanism can cut the semi-cured sheet 400 into certain specifications on the workbench 1010, so that the cut semi-cured sheet 400 is at the first position 1011 of the support surface, and the material moving mechanism is used to transfer the semi-cured sheet 400 at the first position 1011 to the second position 1012 of the support surface, and then the stacking mechanism is used to lift the semi-cured sheet 400 at the second position 1012.

[0028] The drilling device 300 is connected to the frame 1000 and is located above the workbench 1010, and is used to drill holes in the stacked prepregs 400 at the third position 1013. The drilling device 300 can use a high-speed rotating drill bit and cooperate with a precise control system to achieve precise drilling of the prepregs 400.

[0029] In a specific implementation, the feeding device 100 feeds the prepreg 400 from the storage area to the first position 1011. The cutting mechanism cuts the prepreg 400.

Through the above-mentioned embodiments, the pre-stacked drilling machine provided by the present invention realizes the integrated processing of cutting, stacking and drilling of the prepreg 400, significantly improves the production efficiency and processing accuracy, reduces the production cost and space occupancy, and has high practical value and application prospects.

[0030] Reference Figure 2 , Figure 3 and Figure 4 In order to clamp and stack the prepreg 400 more stably, especially when handling a prepreg 400 of large size or heavy weight, a plurality of first clamps 223 and second clamps 232 are provided. A plurality of first clamps 223 are arranged side by side along one horizontal side of the prepreg 400, and similarly, a plurality of second clamps 232 are arranged side by side along the other horizontal side of the prepreg 400. Such a design ensures that the prepreg 400 can be evenly stressed during the stacking process, avoids deformation or offset caused by single-point clamping, and improves the accuracy and stability of the stacking. It also enhances the clamping strength and stability of the prepreg 400, and improves the accuracy and consistency of the stacking.

[0031] Specifically, the first clamp 223 includes a first clamp block 224 and a first cylinder 225121, and the first cylinder 225121 drives the first clamp block 224 to press down to clamp one side of the prepreg 400. The bottom of the first aligning member 222 is connected to a first support strip 226, which is located below the first clamp block 224 and forms an upper and lower clamping structure together with the first clamp block 224. Similarly, the second clamp 232 includes a second clamp block 233 and a second cylinder 234, and a second support strip 235 located below. Such a design ensures that the prepreg 400 can be firmly clamped during the stacking process, while avoiding damage caused by excessive clamping force, achieving stable clamping of the prepreg 400, and protecting the prepreg 400 from damage. The efficiency and accuracy of stacking are improved.

[0032] In some embodiments, the stacking mechanism includes an anti-deflection assembly, which is connected to the lifting assembly 210. The anti-deflection assembly includes a pressure strip 240 and a third cylinder 241. The pressure strip 240 is located above the workbench 1010 and extends along the moving direction of the prepreg 400. The third cylinder 241 drives the pressure strip 240 to press down, pressing the prepreg 400 against the workbench 1010, thereby preventing deviation during the stacking process, ensuring the position accuracy of the prepreg 400 during the stacking process, and improving the stability and consistency of the stacking.

The mounting member 120 is disposed on the frame 1000, and the feeding roller 124 is detachably disposed on the mounting member 120 for easy replacement and maintenance. The second driving member 125 drives the feeding roller 124 to rotate to realize the conveyance of the prepreg 400.

[0034] Specifically, the mounting component 120 includes a mounting frame 123 and a fourth cylinder. The mounting frame 123 protrudes to form a support portion 122, and the fourth cylinder is arranged above the support portion 122. The end of the feeding roller 124 is slidably connected to the support portion 122, and the fourth cylinder cooperates with the side wall of the mounting frame 123 to position the end of the feeding roller 124, thereby achieving stable installation and adjustment of the feeding roller 124.

[0035] It should be noted that the frame 1000 is provided with a deviation correction component for correcting the position of the prepreg 400. The deviation correction component includes a detector 140, a third driving member and a guide member 111. The edge of the prepreg 400 passes through the detector 140, and when a deviation is detected, the third driving member drives the conveying unit to move in the horizontal direction, and the position is corrected through the movable end of the guide member 111.

[0036] Reference Figure 4 The cutting mechanism includes a cutting seat 250, a cutting knife 251 and a first power member 252.

The cutting knife 251 and the cutting seat 250 cooperate to cut the prepreg 400, thereby realizing a precise cutting operation.

[0037] Furthermore, a pressing mechanism is provided on one side of the cutting mechanism close to the stacking mechanism. The pressing mechanism includes a U-shaped pressing plate 260 and a second power member 261, and the U-shaped pressing plate is located above the workbench 1010. When the cutting mechanism cuts the prepreg 400, the second power member 261 drives the U-shaped pressing plate to press down, pressing the prepreg 400 onto the workbench 1010, preventing deviation during the cutting process and ensuring the position accuracy during the cutting process.

[0038] Reference Figure 1 It should be noted that the drilling device 300 includes a mounting plate 310 and a plurality of self-priming waste drill bits 310 movably connected to the mounting plate 310. The self-priming waste drill bits 310 are provided with an air pipe 320, and the air pipe 320 is externally connected to a negative pressure component for sucking waste generated during drilling.
