Description

Technical Field

[0001] This utility model relates to the technical field of stacking equipment, and in particular to a cutting and stacking device. Background Technology

[0002] In some prepreg production processes, a cutting machine is used to cut the prepreg into certain sizes. Then, workers stack multiple cut prepregs together and drill holes in the stacked prepregs to improve drilling efficiency.

[0003] However, when prepregs are cut and manually stacked, it is difficult to align them precisely, resulting in low stacking efficiency. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a cutting and stacking device that can automatically stack prepreg sheets, making the prepreg sheets stacked neatly and improving the stacking accuracy.

[0005] A cutting and stacking device according to an embodiment of the present invention includes: a workbench with a support surface on top, the support surface being used to support a prepreg, the support surface having a first position and a second position; a cutting mechanism for cutting the prepreg on the support surface at the first position; a material transfer mechanism for pulling the prepreg cut by the cutting mechanism from the first position to the second position; and a stacking mechanism including a lifting component and a first lifting unit for driving the lifting component to rise and fall, the lifting component being capable of stacking the prepreg on the second position of the support surface; the lifting component including a first gripper and a second gripper arranged horizontally opposite to each other, and a first translation unit for driving the first gripper and the second gripper to move closer or further apart, the first gripper including a first aligning member and a first clamping device connected to the first aligning member, the second gripper including a second aligning member and a second clamping device connected to the second aligning member, the first aligning member and the second aligning member being capable of aligning the stacked prepreg in a horizontal direction, the first clamping device being used to clamp one side of the prepreg, and the second clamping device being used to clamp the other side of the prepreg.

[0006] A cutting and stacking device according to an embodiment of the present utility model has at least the following beneficial effects:

[0007] 1. This utility model, by setting up a cutting mechanism, a material transfer mechanism, and a stacking mechanism, allows the cutting mechanism to cut the prepreg into certain specifications on the worktable. After the prepreg is cut, it is placed at a first position on the support surface. The material transfer mechanism then transfers the prepreg at the first position to a second position on the support surface. The stacking mechanism then lifts the prepreg at the second position. When the next prepreg arrives at the second position, the stacking mechanism stacks the lifted prepreg on top of the prepreg at the second position on the support surface. This achieves automated stacking of prepreg and improves the stacking efficiency of prepreg.

[0008] 2. This utility model, by setting up a lifting component and a first lifting unit, utilizes the first lifting unit to drive the lifting component to rise and fall, enabling the lifting component to lift and stack the prepreg sheets. Furthermore, by setting up a first gripper, a second gripper, and a first translation component, the first gripper includes a first aligning member and a first clamping device, and the second gripper includes a second aligning member and a second clamping device. When the prepreg sheet is lifted, the first lifting unit drives the lifting component to fall, causing the first and second grippers to fall synchronously. The first translation component drives the first and second grippers to move closer together, with the first aligning member abutting against one horizontal side of the prepreg sheet and the second aligning member abutting against the other horizontal side of the prepreg sheet. Next, the first and second aligning components adjust the position of the prepreg. The first and second clamps clamp the two sides of the prepreg respectively. The first lifting unit drives the lifting assembly to rise. When the prepregs are stacked, after the next prepreg reaches the second position, the first lifting unit drives the lifting assembly to descend and approach the prepreg near the support surface. The first and second clamps release the clamps on the prepreg. The first translation component drives the first and second jaws to move away from each other, so that the prepregs are stacked neatly. This prevents the prepregs from being stacked crookedly, improves the stacking accuracy, and facilitates subsequent drilling of the stacked prepregs.

[0009] According to an embodiment of the present invention, a cutting and stacking device is provided in which multiple first clamps and multiple second clamps are provided. The multiple first clamps are arranged side by side along one horizontal side of the semi-cured sheet, and the multiple second clamps are arranged side by side along the other horizontal side of the semi-cured sheet.

The first clamping block and the first support strip clamp one side of the prepreg. The second clamping device includes a second clamping block and a second cylinder that drives the second clamping block to press down. The bottom of the second aligning member is connected to a second support strip, which is located below the second clamping block. The second clamping block and the second support strip clamp the other side of the prepreg.

The stacking mechanism includes an anti-deviation component, which is connected to the lifting component. The anti-deviation component includes a pressure bar and a third cylinder that drives the pressure bar to press down. The pressure bar is located above the worktable and extends along the moving direction of the prepreg. The pressure bar is used to press the prepreg tightly onto the worktable.

[0013] According to an embodiment of the present invention, a cutting and stacking device has an arc-shaped protrusion at the bottom of the pressure strip, which is used to abut against the prepreg.

[0014] According to an embodiment of the present invention, a cutting and stacking device is provided, wherein the cutting mechanism includes a cutting seat, a cutting blade located above the cutting seat, and a first power component that drives the cutting blade to rise and fall. The cutting seat is disposed on the worktable, and the cutting blade and the cutting seat cooperate to cut the prepreg.

[0015] According to an embodiment of the present utility model, a cutting and stacking device is provided with a pressing mechanism on the side of the cutting mechanism near the stacking mechanism. The pressing mechanism includes a U-shaped pressing plate and a second power member that drives the U-shaped pressing plate to press down. The U-shaped pressing plate is located above the worktable.

[0030] A cutting and stacking device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0031] Reference Figure 1 The present invention aims to provide an embodiment of a cutting and stacking device.

[0032] A cutting and stacking device according to an embodiment of this utility model, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a workbench 100, a cutting mechanism, a transferring mechanism, and a stacking mechanism. The top of the workbench 100 has a support surface for supporting the prepreg. The support surface has a first position and a second position. The cutting mechanism is used to cut the prepreg on the support surface at the first position. The transferring mechanism is used to pull the prepreg cut by the cutting mechanism from the first position to the second position.

[0033] Understandably, by setting up a cutting mechanism, a material transfer mechanism, and a stacking mechanism, the cutting mechanism can cut the prepreg into certain specifications on the worktable 100, so that the cut prepreg is at the first position on the support surface. The material transfer mechanism then transfers the prepreg at the first position to the second position on the support surface, and the stacking mechanism lifts the prepreg at the second position. After the next prepreg arrives at the second position, the stacking mechanism stacks the lifted prepreg on top of the prepreg at the second position on the support surface. Thus, automated stacking of prepreg is achieved, improving the stacking efficiency of prepreg.

[0034] A cutting and stacking device according to an embodiment of this utility model, referring to... Figure 1 , Figure 2 and Figure 3 The stacking mechanism includes a lifting component 110 and a first lifting unit 120 that drives the lifting component 110 to rise and fall. The lifting component 110 can stack the prepreg on a second position on the support surface. The lifting component 110 includes a first gripper 130 and a second gripper 140 arranged horizontally opposite each other, and a first translation unit 150 that drives the first gripper 130 and the second gripper 140 to move closer or further apart. The first gripper 130 includes a first aligning member 160 and a first clamping device 170 connected to the first aligning member 160. The second gripper 140 includes a second aligning member 180 and a second clamping device 190 connected to the second aligning member 180. The first aligning member 160 and the second aligning member 180 can align the stacked prepreg in a horizontal direction. The first clamping device 170 is used to clamp one side of the prepreg, and the second clamping device 190 is used to clamp the other side of the prepreg.

[0035] Understandably, by setting up a lifting assembly 110 and a first lifting unit 120, the first lifting unit 120 drives the lifting assembly 110 to rise and fall, enabling the lifting assembly 110 to lift the prepreg and stack the prepregs. Then, by setting up a first gripper 130, a second gripper 140, and a first translation assembly, the first gripper 130 includes a first aligning member 160 and a first clamping device 170, and the second gripper 140 includes a second aligning member 180 and a second clamping device 190. When the prepreg is lifted, the first lifting unit 120 drives the lifting assembly 110 to fall, causing the first gripper 130 and the second gripper 140 to fall synchronously. The first translation assembly drives the first gripper 130 and the second gripper 140 to move closer together, with the first aligning member 160 abutting against the horizontal side of the prepreg, and the second aligning member 190... Part 180 abuts against the other side of the semi-cured sheet, causing the first aligning part 160 and the second aligning part 180 to adjust the position of the semi-cured sheet. The first clamping device 170 and the second clamping device 190 clamp the two sides of the semi-cured sheet respectively. The first lifting unit 120 drives the lifting component 110 to rise. When the semi-cured sheets are stacked, after the next semi-cured sheet arrives at the second position, the first lifting unit 120 drives the lifting component 110 to descend and approach the semi-cured sheet near the support surface. The first clamping device 170 and the second clamping device 190 release the clamping device on the semi-cured sheet. The first translation component drives the first jaw 130 and the second jaw 140 to move away from each other, so that the semi-cured sheets are stacked neatly, thus avoiding the semi-cured sheets from being stacked crookedly, improving the stacking accuracy, and facilitating subsequent drilling of the stacked semi-cured sheets.

[0036] It should be noted that the first lifting unit 120 can be a linear motor module, and the first translation unit 150 can be composed of two linear motor modules. The two linear motor modules drive the first gripper 130 and the second gripper 140 to move respectively. The specific structure of the first lifting unit 120 and the first translation unit 150 is not specifically limited here.

[0037] In some embodiments of this utility model, the cutting mechanism includes a cutting seat 300, a cutting blade 310 located above the cutting seat 300, and a first power component 320 that drives the cutting blade 310 to rise and fall. The cutting seat 300 is disposed on the worktable 100, and the cutting blade 310 and the cutting seat 300 cooperate to cut the prepreg.

[0038] It should be noted that the first power component 320 can be either an electric cylinder or a pneumatic cylinder, and no specific limitation is made here.

[0039] Therefore, the first power is used to drive the cutter 310 to descend, and the cutter 310 and the cutting seat 300 work together to cut the prepreg into a certain size.

[0040] In some embodiments of this utility model, a pressing mechanism is provided on the side of the cutting mechanism near the stacking mechanism. The pressing mechanism includes a U-shaped pressing plate 330 and a second power member 340 that drives the U-shaped pressing plate 330 to press down. The U-shaped pressing plate 330 is located above the workbench 100. When the cutting mechanism cuts the prepreg, the U-shaped pressing plate 330 is used to press the prepreg onto the workbench 100.

[0041] It should be noted that the second power component 340 can be either an electric cylinder or a pneumatic cylinder, and no specific limitation is made here.

[0042] Understandably, the second power is used to drive the U-shaped pressure plate 330 to descend, so that the U-shaped pressure plate 330 can press the prepreg tightly before cutting, thus avoiding the prepreg from shifting position during cutting and causing the material transfer mechanism to fail to accurately deliver the prepreg.

[0043] Furthermore, the U-shaped pressure plate 330 has a large outer dimension, which allows it to press the prepreg tightly onto the worktable 100. In addition, the mass of the U-shaped pressure plate 330 is not large, ensuring that the second power component 340 moves quickly.

[0044] In some embodiments of this utility model, an electrostatic eliminator 350 is provided on one side of the cutting mechanism, which is used to eliminate static electricity from the prepreg.

[0045] Understandably, by setting up the static eliminator 350, the static electricity of the prepreg is eliminated, thus preventing the stacked prepreg sheets from sticking together and becoming misaligned due to static electricity.

[0046] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 The material transfer mechanism includes a clamping finger 360, a second lifting unit 370 connected to the clamping finger 360, and a second translation unit 380 connected to the second lifting unit 370. The clamping finger 360 is used to clamp one side of the prepreg. The worktable 100 is provided with a clearance channel 390, which extends along the moving direction of the prepreg and accommodates the passage of the clamping finger 360.

[0047] Therefore, the second lifting unit 370 drives the gripper 360 to rise, and the gripper 360 passes through the clearance channel 390 to grip one side of the prepreg in the first position. The second translation unit 380 drives the gripper 360 to move from the first position to the second position, so that the movement position of each prepreg is consistent, ensuring that the prepregs are accurately stacked.

[0048] It should be noted that the second lifting unit 370 can be a cylinder, and the second translation unit 380 can be a linear motor module; no specific limitations are made here.

[0049] In some embodiments of this utility model, multiple first clamps 170 and multiple second clamps 190 are provided. Multiple first clamps 170 are arranged side by side along one horizontal side of the prepreg, and multiple second clamps 190 are arranged side by side along the other horizontal side of the prepreg.

[0050] Understandably, multiple first clamps 170 can simultaneously clamp one side of the stacked prepreg, and multiple second clamps 190 can simultaneously clamp the other side of the stacked prepreg, ensuring that the first jaws 130 and the second jaws 140 can stably lift the stacked prepreg, preventing the prepreg from coming loose when lifted, and reducing the possibility of positional displacement when the stacked prepreg is lifted.

[0051] In some embodiments of this utility model, reference is made to Figure 5 The first clamping device 170 includes a first clamping block 200 and a first cylinder 210 that drives the first clamping block 200 to press down. The bottom of the first aligning member 160 is connected to a first support strip 220, which is located below the first clamping block 200. The first clamping block 200 and the first support strip 220 clamp one side of the prepreg. The second clamping device 190 includes a second clamping block 230 and a second cylinder 240 that drives the second clamping block 230 to press down. The bottom of the second aligning member 180 is connected to a second support strip 250, which is located below the second clamping block 230. The second clamping block 230 and the second support strip 250 clamp the other side of the prepreg.

[0052] Understandably, the first clamping block 200 is lowered by the first cylinder 210, and the first clamping block 200 and the first support strip 220 can clamp one side of the stacked prepreg sheets from top to bottom. The second clamping block 230 is lowered by the second cylinder 240, and the second clamping block 230 and the second support strip 250 can clamp the other side of the stacked prepreg sheets from top to bottom. The first clamping device 170 and the second clamping device 190 with this structure have a large clamping force, making it difficult for the stacked prepreg sheets to loosen when lifted.

[0053] Furthermore, the first pallet strip 220 and the second pallet strip 250 are small in size and do not take up much space. They also help to reduce the weight of the first gripper 130 and the second gripper 140, thereby improving the moving efficiency of the first gripper 130 and the second gripper 140.

[0054] Because the prepreg in the second position is in close contact with the support surface, the first support strip 220 and the second support strip 250 cannot easily extend into the bottom of the prepreg. In some embodiments of this utility model, referring to... Figure 3The workbench 100 is provided with a clearance groove 260. When the first gripper 130 and the second gripper 140 are brought close together, the clearance groove 260 is used to accommodate and avoid the first support strip 220 and the second support strip 250. This avoids interference and friction between the first support strip 220 and the second support strip 250 and the workbench 100, making it easier for the first support strip 220 and the second support strip 250 to extend into the bottom of the prepreg so as to smoothly lift the prepreg.

[0055] To prevent the first gripper 130 and the second gripper 140 from contacting the bottom of the prepreg when they come close together, which would cause the prepreg to shift position, and also to prevent the first gripper 130 and the second gripper 140 from moving away from each other when the lifting component 110 stacks the prepregs, which would also cause the prepreg to shift position, in some embodiments of this utility model, the stacking mechanism includes an anti-deviation component connected to the lifting component 110. The anti-deviation component includes a pressure bar 270 and a third cylinder 280 that drives the pressure bar 270 to press down. The pressure bar 270 is located above the worktable 100 and extends along the direction of movement of the prepreg. The pressure bar 270 is used to press the prepreg onto the worktable 100, thereby preventing the prepreg from shifting position and ensuring that the prepregs can be stacked accurately.

[0056] In a further embodiment of this utility model, referring to Figure 5 The bottom of the pressure strip 270 has an arc-shaped protrusion 290, which is used to abut against the prepreg.

[0057] As the first clamp 130 and the second clamp 140 lift the side of the semi-cured plate during the semi-curing stacking, the semi-cured plate will bend to a certain extent. The pressure strip 270 uses the arc-shaped protrusion 290 to abut against the semi-cured sheet to avoid the pressure strip 270 damaging the semi-cured sheet.

[0058] In summary, the working principle of this embodiment is as follows:

[0059] First, the static eliminator 350 eliminates static electricity from the prepreg. Then, the second power drives the U-shaped pressure plate 330 to descend, pressing the prepreg tightly before cutting. Next, the first power drives the cutter 310 to descend, and the cutter 310 and the cutting seat 300 work together to cut the prepreg into certain specifications.

[0060] Next, the second lifting unit 370 drives the gripper 360 to rise, and the gripper 360 passes through the clearance channel 390 to grip one side of the semi-cured sheet at the first position. The second translation unit 380 drives the gripper 360 to move from the first position to the second position.

[0061] Next, the first lifting unit 120 drives the lifting assembly 110 to descend, causing the first gripper 130 and the second gripper 140 to descend synchronously. The third cylinder 280 drives the pressure strip 270 to descend, pressing the prepreg onto the worktable 100. The first translation assembly drives the first gripper 130 and the second gripper 140 to move closer together. The first aligning member 160 abuts against the horizontal side of the prepreg, and the second aligning member 180 abuts against the other horizontal side of the prepreg, allowing the first aligning member 160 and the second aligning member 180 to adjust the position of the prepreg. The first clamping device 170 and the second clamping device 190 clamp the two sides of the prepreg respectively. The third cylinder 280 drives the pressure strip 270 to rise, and the first lifting unit 120 drives the lifting assembly 110 to rise, waiting for the next prepreg.

[0062] After the next prepreg arrives at the second position, the first lifting unit 120 drives the lifting component 110 to lower the prepreg close to the support surface. The first clamp 170 and the second clamp 190 release the prepreg. The first translation component drives the first gripper 130 and the second gripper 140 to move away from each other, thereby allowing the prepregs to be stacked.

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.
