[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This utility model proposes a pre-stacked drilling machine, comprising a frame 1000, a feeding device 100, a cutting and stacking device 200, and a drilling device 300. The frame 1000 is equipped with a worktable 1010, the top of which has a first position 1011, a second position 1012, and a third position 1013 for supporting prepreg sheets 400 for cutting, stacking, and drilling. The feeding device 100 is connected to the frame 1000 and is used to transport multiple prepreg sheets 400. The cutting and stacking device 200 is connected to the frame 1000 and located at the rear end of the feeding device 100. It includes a cutting mechanism and a stacking mechanism. The cutting mechanism is connected to the frame 1000 and located above the worktable 1010, used to cut the prepreg 400 at a first position 1011. The stacking mechanism includes a lifting assembly 210 and a first lifting unit 211 that drives the lifting assembly 210 to rise and fall. The lifting assembly 210 can stack the prepreg 400 on a second position 1012. The lifting assembly 210 includes a first gripper 220 and a second gripper 230 arranged horizontally opposite to each other, and a first lifting unit 211 that drives the first... A first translation unit 221 is used to move the gripper 220 and the second gripper 230 closer together or further apart. The first gripper 220 includes a first aligning member 222 and a first clamping device 223 connected to the first aligning member 222. The second gripper 230 includes a second aligning member 231 and a second clamping device 232 connected to the second aligning member 231. The first aligning member 222 and the second aligning member 231 can align the stacked prepreg sheets 400 in a horizontal direction. The first clamping device 223 is used to clamp one side of the prepreg sheet 400, and the second clamping device 232 is used to clamp the other side of the prepreg sheet 400. A drilling device 300 is connected to the frame 1000 and located on the worktable 1010, and is used to drill holes in the stacked prepreg sheets 400 at a third position 1013.
[0029] In a specific embodiment, the frame 1000 serves as the supporting structure for the entire device, and a workbench 1010 is mounted on it. The top of the workbench 1010 has three key positions: the first position 1011 is used for cutting the prepreg 400, the second position 1012 is used for stacking the prepreg 400, and the third position 1013 is used for drilling holes in the stacked prepreg 400. These three positions ensure the continuity and accuracy of the processing through precise mechanical positioning.
[0030] Furthermore, the feeding device 100 is connected to the frame 1000 and includes a conveying mechanism driven by a first driving member. The conveying mechanism has at least three sets of conveying units, each set including a loading component 110 and a feeding component 130. The first driving member drives the feeding component 130 to reciprocate vertically, conveying the prepreg 400 from the storage area to different positions on the worktable 1010. It should be noted that the first driving member can be a cylinder or a servo motor.
[0031] 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. The cutting mechanism is connected to the frame 1000 and located above the worktable 1010, and is used to precisely cut the prepreg 400 at the first position 1011. The stacking mechanism includes a lifting assembly 210 and a first lifting unit 211, and the lifting assembly 210 is driven to lift by the first lifting unit 211. The lifting assembly 210 consists of a first gripper 220 and a second gripper 230 arranged horizontally opposite to each other, and the two grippers move closer or further apart through a first translation unit 221. The first gripper 220 and the second gripper 230 are respectively provided with a first aligning member 222 and a second aligning member 231, and a first clamping device 223 and a second clamping device 232 connected thereto. During the stacking process, the first aligning member 222 and the second aligning member 231 move relative to each other in the horizontal direction to align the stacked prepreg sheets 400, while the first clamp 223 and the second clamp 232 clamp the two sides of the prepreg sheets 400 respectively to ensure the neatness and stability of the stack.
[0032] Understandably, the cutting mechanism can cut the prepreg 400 into certain specifications on the workbench 1010, so that the cut prepreg 400 is on the first position 1011 of the support surface. The material transfer mechanism transfers the prepreg 400 at the first position 1011 to the second position 1012 of the support surface. Then, the stacking mechanism lifts the prepreg 400 at the second position 1012. After the next prepreg 400 arrives at the second position 1012, the stacking mechanism stacks the lifted prepreg 400 on the prepreg 400 at the second position 1012 of the support surface. Thus, the prepreg 400 is stacked automatically, improving the stacking efficiency of the prepreg 400.
[0033] Furthermore, by setting up a lifting assembly 210 and a first lifting unit 211, the first lifting unit 211 drives the lifting assembly 210 to rise and fall, enabling the lifting assembly 210 to lift the prepreg 400 and stack the prepreg 400. Then, by setting up a first gripper 220, a second gripper 230, and a first translation assembly, the first gripper 220 includes a first aligning member 222 and a first clamping device 223, and the second gripper 230 includes a second aligning member 231 and a second clamping device 232. When the prepreg 400 is lifted, the first lifting unit 211 drives the lifting assembly 210 to fall, causing the first gripper 220 and the second gripper 230 to fall synchronously. The first translation assembly drives the first gripper 220 and the second gripper 230 to move closer together. The first aligning member 222 abuts against the horizontal side of the prepreg 400, and the second aligning member 231 abuts against the horizontal side of the prepreg 400. The first clamping component 222 and the second clamping component 231 adjust the position of the prepreg 400. The first clamping device 223 and the second clamping device 232 clamp the two sides of the prepreg 400 respectively. The first lifting unit 211 drives the lifting component 210 to rise. When the prepregs 400 are stacked, after the next prepreg 400 reaches the second position 1012, the first lifting unit 211 drives the lifting component 210 to descend and approach the prepreg 400 near the support surface. The first clamping device 223 and the second clamping device 232 release the clamping device of the prepreg 400. The first translation component drives the first gripper 220 and the second gripper 230 to move away from each other, so that the prepregs 400 are stacked neatly, thus avoiding the prepregs 400 being stacked crookedly, improving the stacking accuracy, and facilitating subsequent drilling of the stacked prepregs 400.
[0034] The drilling device 300 is connected to the frame 1000 and located above the worktable 1010, and is used to perform drilling operations on the stacked prepreg sheets 400 at the third position 1013. The drilling device 300 can use a high-speed rotating drill bit, in conjunction with a precise control system, to achieve precise drilling of the prepreg sheets 400.
[0035] In specific implementation, the feeding device 100 delivers the prepreg 400 from the storage area to the first position 1011. The cutting mechanism cuts the prepreg 400. The feeding device 100 delivers the cut prepreg 400 to the second position 1012. The stacking mechanism stacks the prepreg 400 neatly using the lifting component 210. The feeding device 100 delivers the stacked prepreg 400 to the third position 1013. The drilling device 300 drills holes in the stacked prepreg 400. Through the above implementation, the pre-stacked drilling machine provided by this utility model achieves integrated processing of prepreg cutting, stacking, and drilling, significantly improving production efficiency and processing accuracy, reducing production costs and space occupation, and has high practical value and application prospects.
[0036] Reference Figure 2 , Figure 3 and Figure 4 To more stably clamp and stack the prepreg 400, especially when handling large or heavy prepregs 400, multiple first clamps 223 and second clamps 232 are provided. Multiple first clamps 223 are arranged side-by-side along one horizontal side of the prepreg 400, and similarly, multiple second clamps 232 are arranged side-by-side along the other horizontal side of the prepreg 400. This design ensures that the prepreg 400 is evenly stressed during stacking, avoiding deformation or displacement caused by single-point clamping, and improving the accuracy and stability of stacking. Furthermore, it enhances the clamping force and stability of the prepreg 400, improving the accuracy and consistency of stacking.
[0037] Specifically, the first clamping device 223 includes a first clamping block 224 and a first cylinder 225121. The first cylinder 225121 drives the first clamping block 224 to press down and clamp one side of the prepreg 400. A first support strip 226 is connected to the bottom of the first aligner 222. The first support strip 226 is located below the first clamping block 224, forming a clamping structure together with the first clamping block 224. Similarly, the second clamping device 232 includes a second clamping block 233, a second cylinder 234, and a second support strip 235 located below. This design ensures that the prepreg 400 can be firmly clamped during stacking, while avoiding damage caused by excessive clamping force, achieving stable clamping of the prepreg 400 and protecting it from damage. This improves the efficiency and accuracy of stacking.
[0038] In some embodiments, the stacking mechanism includes an anti-deviation component connected to the lifting component 210. The anti-deviation component includes a pressure bar 240 and a third cylinder 241. The pressure bar 240 is located above the worktable 1010 and extends along the direction of movement of the prepreg 400. The third cylinder 241 drives the pressure bar 240 downwards, pressing the prepreg 400 firmly onto the worktable 1010, thereby preventing deviation during stacking, ensuring the positional accuracy of the prepreg 400 during stacking, and improving the stability and consistency of the stacking process.
[0039] Reference Figure 5 and Figure 6 The conveying unit includes a feeding roller 124, a second drive component 125, and a mounting component 120. The mounting component 120 is mounted on the frame 1000, and the feeding roller 124 is detachably mounted on the mounting component 120 for easy replacement and maintenance. The second drive component 125 drives the feeding roller 124 to rotate, thereby conveying the semi-cured sheet 400.
[0040] Specifically, the mounting component 120 includes a mounting bracket 123 and a fourth cylinder. The mounting bracket 123 protrudes to form a support portion 122, and the fourth cylinder is positioned 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 bracket 123 to position the end of the feeding roller 124, thereby achieving stable installation and adjustment of the feeding roller 124.
[0041] It should be noted that the frame 1000 is equipped with a correction assembly for correcting the position of the prepreg 400. The correction assembly includes a detector 140, a third drive unit, and a guide component 111. The edge of the prepreg 400 passes through the detector 140. When an offset is detected, the third drive unit drives the conveying unit to move in the horizontal direction, and the position is corrected through the movable end of the guide component 111.
[0042] Reference Figure 4 The cutting mechanism includes a cutting seat 250, a cutting blade 251, and a first power component 252. The cutting seat 250 is mounted on the worktable 1010, and the cutting blade 251 is located above the cutting seat 250 and is driven to move up and down by the first power component 252. The cutting blade 251 and the cutting seat 250 work together to cut the prepreg sheet 400, achieving precise cutting operations.
[0043] Furthermore, a clamping mechanism is provided on the side of the cutting mechanism near the stacking mechanism. The clamping mechanism includes a U-shaped pressure plate 260 and a second power component 261, with the U-shaped pressure plate located above the worktable 1010. When the cutting mechanism cuts the prepreg 400, the second power component 261 drives the U-shaped pressure plate to press down, pressing the prepreg 400 firmly onto the worktable 1010 to prevent displacement during the cutting process and ensure positional accuracy during the cutting process.
[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
