[0033] See also Figure 1 One embodiment of the utility model provides a lamination device, including a lamination table, a lamination robot and a feeding device. The feeding device is used to unwind and output a material strip A, and cut the material strip A into sheets. The lamination robot is used to absorb the sheets formed by the cutting of the feeding device, and stack the absorbed sheets on the lamination table. It should be noted that the sheets cut by the feeding device can be aluminum-plastic films or FEP films. Of course, in other embodiments, the sheets cut by the feeding device can also be other sheets that need to be stacked on the lamination table, which is not limited here.

[0034] In the embodiment of the present application, the loading device includes an unwinding component 10, a cutting component 20, an adsorption component 30 and a material pulling component 40. The unwinding component 10 is used to unwind and output the material strip A downstream. The cutting component 20 is arranged downstream of the unwinding component 10, and is used to cut off the material strip A passing through. The adsorption component 30 is arranged downstream of the cutting component 20, and includes an adsorption platform 31 for adsorbing the material strip A passing through. The material pulling component 40 is used to clamp the material strip A at the cutting component 20, and pull the clamped material strip A onto the adsorption platform 31.

[0035] In the actual use of the above-mentioned loading device, the unwinding component 10 unwinds the material strip A to the cutting component 20. First, the material pulling component 40 moves to the cutting component 20 and clamps the starting end of the material strip A. Then, the material pulling component 40 moves to the adsorption platform 31 until a certain length of the material strip A is pulled onto the adsorption platform 31. Then, the material pulling component 40 releases the starting end of the material strip A, and the adsorption platform 31 adsorbs and fixes the material strip A thereon. Then, the cutting component 20 cuts off the material strip A passing through, and at this time, the part of the material strip A adsorbed and fixed by the adsorption platform 31 is cut off, and this part is the material sheet. Then, the adsorption platform 31 stops adsorbing the material sheet, and the stacking robot absorbs the material sheet on the adsorption platform 31. Then, the stacking robot stacks the absorbed material sheets on the stacking table.

[0036] In this way, the feeding device in the present application pulls out a certain length of the material strip A to the adsorption platform 31 each time through the material pulling component 40, and cuts it with the cutting component 20, so as to form a sheet of material of the required length on the adsorption platform 31 for the stacking robot to take away and stack. Compared with the prior art, the present application directly cuts the material strip A to form a sheet of material, and the sheet of material is adsorbed and fixed by the adsorption platform 31, so that the sheet of material remains flat, ensuring that the stacking robot can easily take the sheet, which greatly improves the stacking efficiency.

[0037] Specifically in the embodiment, the loading device further includes a mounting seat 80 and a deflection correction driving member 90. The unwinding assembly 10 is arranged on the mounting seat 80, so that the unwinding assembly 10 and the material strip A unwinding from the unwinding assembly 10 can move along with the mounting seat 80. The mounting seat 80 is connected to the driving end of the deflection correction driving member 90, so that the deflection correction driving member 90 can drive the mounting seat 80 to move, thereby driving the unwinding assembly 10 and the material strip A unwinding from the unwinding assembly 10 to correct the deflection, which is beneficial to improve the position accuracy of the material sheet subsequently formed on the adsorption platform 31, and ensure that the stacking robot can accurately take the sheet.

[0038] Furthermore, the moving direction of the mounting seat 80 is parallel to the width direction of the material strip A unwound by the unwinding assembly 10, that is, the deflection correction drive 90 can drive the mounting seat 80 to move along the width direction of the material strip A, thereby driving the material strip A to adjust its position along its width direction (i.e., deflection correction), which is beneficial to improve the position accuracy of the material sheet subsequently formed on the adsorption platform 31. It should be noted that the deflection correction drive 90 can be a linear motor, of course, it can also be other types of linear drive modules, as long as it can drive the mounting seat 80 to move along the width direction of the material strip A, and it is not limited here.

[0039] Furthermore, the feeding device further includes a guide rail 81 extending longitudinally along the width direction of the material strip A. A slider 82 is mounted on the mounting seat 80, and the slider 82 is disposed on the guide rail 81 and is movable along the guide rail 81. In this way, the movement of the mounting seat 80 is guided by the movement of the slider 82 along the guide rail 81, so that the deviation correction movement of the material strip A is more accurate and reliable.

[0040] Specifically in the embodiment, the feeding device also includes a correction sensor 50 arranged between the cutting component 20 and the unwinding component 10. The correction sensor 50 is used to detect the position of the passing material strip A in its own width direction. The correction sensor 50 is communicatively connected with the correction drive 90, so that the correction drive 90 can drive the mounting seat 80 to move according to the detection result of the correction sensor 50, thereby driving the material strip A to correct the deviation. In this way, when the correction sensor 50 detects that there is a deviation in the position of the material strip A in its own width direction, the correction drive 90 controls the mounting seat 80 to move along the width direction of the material strip A, thereby driving the material strip A to adjust its position along its own width direction (i.e., correct the deviation).

[0041] In an embodiment of the present application, the unwinding assembly 10 includes an unwinding mechanism 11 and a buffer mechanism 12, both of which are mounted on the above-mentioned mounting seat 80. The unwinding mechanism 11 is used to unwind and output the material strip A downstream. The buffer mechanism 12 is arranged downstream of the unwinding mechanism 11, and is used to feed the material strip A for winding and buffering the material strip A. In this way, the material strip A is buffered by the buffer mechanism 12, so that when the pulling assembly 40 pulls the material strip A downstream, the material strip A buffered by the buffer mechanism 12 is consumed, thereby avoiding directly pulling the material strip A on the unwinding mechanism 11, thereby reducing the risk of breaking the material strip A.

[0042] Furthermore, the unwinding assembly 10 further includes a first dust removal mechanism 13 and a second dust removal mechanism 14 arranged between the unwinding mechanism 11 and the buffer mechanism 12. The first dust removal mechanism 13 and the second dust removal mechanism 14 are both arranged on the above-mentioned mounting seat 80, and are respectively located on both sides of the passing material belt A, so as to remove dust from the surfaces of both sides of the material belt A respectively, so as to avoid dust on the surface of the subsequently formed sheet.

[0043] Furthermore, the unwinding assembly 10 further includes a static electricity removal mechanism disposed between the unwinding mechanism 11 and the buffer mechanism 12. The static electricity removal mechanism is disposed on the mounting seat 80 and is used to remove static electricity on the passing material belt A. Optionally, the static electricity removal mechanism can be disposed on the first dust removal mechanism 13 and / or the second dust removal mechanism 14.

[0044] In some embodiments, the cutting assembly 20 includes an upper cutter 21, a lower cutter 22, and a cutting drive 23. The upper cutter 21 and the lower cutter 22 are arranged opposite to each other, and a cutting channel through which the material supply tape A passes is formed therebetween. The upper cutter 21 is installed at the driving end of the cutting drive 23, so that the cutting drive 23 can drive the upper cutter 21 to move closer to or away from the lower cutter 22 to cut off the material tape A passing through the cutting channel. In this way, when it is necessary to cut the material tape A, first, the cutting drive 23 drives the upper cutter 21 to gradually move closer to the lower cutter 22 until it cooperates with the lower cutter 22 to cut off the material tape A passing through. Then, the cutting drive 23 drives the upper cutter 21 to move away from the lower cutter 22 until it returns to the initial position. Optionally, the cutting drive 23 can use a cylinder.

[0045] In some embodiments, the feeding device also includes a material pressing assembly 60 arranged on the upstream side of the cutting assembly 20 (i.e., the side of the cutting assembly 20 facing away from the adsorption platform 31). The material pressing assembly 60 includes a pressing plate 61, a pad 62, and a material pressing driving member 63. The pressing plate 61 and the pad 62 are arranged relative to each other, and a material pressing channel through which the feed belt A passes is formed therebetween. The driving end of the material pressing driving member 63 is connected to the pressing plate 61 so that the material pressing driving member 63 can drive the pressing plate 61 to move closer to or away from the pad 62. In this way, before the pulling assembly 40 clamps the starting end of the material belt A at the cutting assembly 20 and pulls the material belt A to move toward the adsorption platform 31, the material pressing driving member 63 drives the pressing plate 61 to move away from the pad 62, so that the pressing plate 61 and the pad 62 release the material belt A. Before the cutting assembly 20 cuts the material strip A, the material pressing driving member 63 drives the pressing plate 61 to move close to the pad 62 until the material strip A is pressed and fixed on the pad 62. That is, before cutting, the material strip A upstream of the cutting position is pressed and fixed on the pad 62 by the pressing plate 61, and the material strip A downstream of the cutting position is adsorbed and fixed by the adsorption platform 31, which is conducive to improving the cutting quality. Optionally, the material pressing driving member 63 can be a cylinder.

[0046] In some embodiments, the feeding device further includes a dust removal component 70 disposed at the cutting component 20. The dust removal component 70 is used to absorb dust generated by the cutting component 20 when cutting the material strip A, thereby preventing dust from being present on the subsequently formed material sheets.

[0047] Furthermore, the dust suction port of the dust removal component 70 is arranged at the lower cutter 22, so that the dust removal component 70 can easily absorb the dust generated by cutting the material strip A.

[0048] In some embodiments, the adsorption assembly 30 also includes a lifting drive 32. The adsorption platform 31 is installed at the driving end of the lifting drive 32, and the lifting drive 32 is used to drive the adsorption platform 31 to move up or down. In this way, when there is no sheet on the adsorption platform 31, the lifting drive 32 drives the adsorption platform 31 to descend. On the one hand, the height of the adsorption platform 31 is convenient for the pulling assembly 40 to move and pull the material. On the other hand, it is convenient to make the height positions of the adsorption platform 31, the pad 62 and the lower cutter 22 basically consistent, which is beneficial to improve the cutting quality and the position accuracy of the sheet. When there is a sheet on the adsorption platform 31, the lifting drive 32 drives the adsorption platform 31 to rise, so that the stacking robot can absorb the sheet on the adsorption platform 31, which is beneficial to further reduce the difficulty of the stacking robot to take the sheet. Optionally, the lifting drive 32 can use a cylinder.

[0049] In some embodiments, the material pulling assembly 40 includes a moving seat 41, a moving driving member 42, and a clamping mechanism 43. The moving seat 41 is connected to the driving end of the moving driving member 42, and the clamping mechanism 43 is installed on the moving seat 41, and the clamping mechanism 43 can clamp or release the material strip A in a controlled manner. The moving driving member 42 is used to drive the moving seat 41 to move, so as to drive the clamping mechanism 43 to move between the cutting assembly 20 and the side of the adsorption platform 31 away from the cutting assembly 20, so that the clamping mechanism 43 clamps the starting end of the material strip A at the cutting assembly 20, and pulls the material strip A onto the adsorption platform 31. In this way, when a sheet is needed on the adsorption platform 31, first, the moving driving member 42 drives the moving seat 41 to move toward the cutting component 20, thereby driving the clamping mechanism 43 to move from the side of the adsorption platform 31 away from the cutting component 20 to the side of the adsorption platform 31 close to the cutting component 20, and clamps the starting end of the material strip A located at the cutting component 20; then, the moving driving member 42 drives the moving seat 41 to move away from the cutting component 20, until the clamping mechanism 43 is driven to move to the side of the adsorption platform 31 away from the cutting component 20, thereby pulling out a certain length of the material strip A to the adsorption platform 31; then, the pressing driving member 63 drives the pressing plate 61 to press the material strip A against the pad 62, the clamping mechanism 43 releases the material strip A, and the adsorption platform 31 adsorbs and fixes the material strip A thereon; then, the upper cutter 21 and the lower cutter 22 of the cutting component 20 cut off the passing material strip A, and at this time, the material strip A located on the adsorption platform 31 is a sheet.

[0050] It should be noted that the moving drive member 42 may be an electric cylinder, or other types of linear modules, as long as it can drive the moving seat 41 to move, and is not limited here.

[0051] Optionally, the clamping mechanism 43 includes a clamping claw cylinder 431 and a clamping claw 433. The clamping claw cylinder 431 is installed on the moving base 41, and the clamping claw 433 is installed at the driving end of the clamping claw cylinder 431. The clamping claw cylinder 431 is used to drive the clamping claw 433 to clamp or release the material strip A.

[0052] Combine the following Figure 1 Explain the working process of the feeding device:

[0053] First, the moving driving member 42 drives the moving base 41 to move from right to left, thereby driving the clamping claw 433 of the clamping mechanism 43 to move to the cutting assembly 20 .

[0054] Then, the clamping claw cylinder 431 of the clamping mechanism 43 drives the clamping claw 433 to clamp the starting end of the material strip A. Then, the moving driving member 42 drives the moving base 41 to move from left to right, thereby driving the clamping claw 433 to move to the side of the adsorption platform 31 away from the cutting assembly 20, so as to pull out a certain length of the material strip A onto the adsorption platform 31.

[0055] Then, the material pressing driving member 63 drives the pressing plate 61 to press the material strip A onto the backing plate 62, and the clamping claw cylinder 431 of the clamping mechanism 43 drives the clamping claw 433 to release the material strip A, and the adsorption platform 31 adsorbs and fixes the material strip A thereon. Then, the upper cutter 21 and the lower cutter 22 of the cutting assembly 20 cut the material strip A passing by, and the material strip A located on the adsorption platform 31 at this time is a sheet.

[0056] Then, the lifting drive member 32 drives the adsorption platform 31 to rise, and the stacking robot takes away the sheet on the adsorption platform 31 .

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
