[0001] The invention relates to a continuous lamination device, belonging to the technical field of optical lamination. Background Art

[0002] The laminating machines currently on the market are used to coat the surfaces of various materials for protection. In the prior art, after the material is coated, the protective film generally needs to be cut, usually manually, and the cut materials are stacked.

Even if a machine is used for cutting, the cut materials are stacked in a single piece, which is not conducive to their subsequent use. Therefore, in order to facilitate subsequent use, the existing laminating machines continuously fold the coated materials and stack the folded materials. However, when folding materials such as light guide plates that have a certain degree of flatness and hardness, it is easy to cause wrinkles, crushing of the materials, scratching of the materials, etc., resulting in a high defect rate.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] See also Figures 1 to 6The continuous lamination device shown in one embodiment of the present invention is used to fold and stack materials. In this embodiment, the material is composed of a plurality of light guide plates 11 and a protective film 12. The plurality of light guide plates 11 are arranged in sequence at a certain interval, and the upper and lower surfaces of each light guide plate 11 are covered with a protective film 12 to connect all the light guide plates 11. In addition, the light guide plate 11 can also be other sheet-like plates with a certain hardness, such as a diffuser, etc., but the material can also be other flexible foldable materials, which is not specifically limited here. In this embodiment, the light guide plates 11 are arranged at equal intervals and there is a gap between adjacent light guide plates 11. The size of the gap can be set according to actual needs, which is not specifically limited here.

[0027] The continuous lamination device includes a bracket 1, a conveying mechanism 2, a receiving platform 3 located at the end of the conveying mechanism 2 and used to place the folded material, a folding mechanism 4 used to fold the material on the conveying mechanism 2 and place it on the receiving platform 3, and a pressing portion 5 located on one side of the receiving platform 3 and used to press the material. The folding mechanism 4 can move in space relative to the conveying mechanism 2 to fold the material on the conveying mechanism 2 onto the receiving platform 3 with the pressing portion 5 as the folding line. The continuous lamination device also includes a control mechanism 13 for controlling the conveying mechanism 2, the receiving platform 3, the folding mechanism 4, the pressing portion 5 and other components. The control mechanism 13 controls the coordinated movement of each component and folds the material smoothly. The bracket 1 is used to support each component of the continuous lamination device. The control mechanism 13, the conveying mechanism 2, the receiving platform 3, the folding mechanism 4, and the pressing portion 5 are all arranged on the bracket 1.

[0028] The conveying mechanism 2 includes a conveyor belt 21 for placing materials, and a first driving member 22 for driving the conveyor belt 21 to move to transport materials. The conveyor belt 21 can also be a structure such as a roller, and the first driving member 22 drives the roller to rotate. The conveying mechanism 2 is a common existing structure and will not be described in detail here.

[0029] The continuous lamination device also includes a track 6 located on both sides of the conveying mechanism 2 and the receiving platform 3. The folding mechanism 4 is located on the track 6 and can move along the track 6, so as to fold the material on the conveying mechanism 2 onto the receiving platform 3 with the pressing portion 5 as the folding line. The folding mechanism 4 includes a flipping assembly arranged on the track 6, and a driving assembly (not shown) for driving the flipping assembly to move. The control mechanism 13 can control the driving assembly to work, so that the driving assembly drives the flipping assembly to reciprocate in the first direction, the second direction and the height direction on the track 6. In this embodiment, the first direction is set as the moving direction of the conveying mechanism 2 to transport the material, such as Figure 1 The second direction is the direction indicated by the arrow a in the horizontal plane and is perpendicular to the first direction a. Figure 1 The direction indicated by arrow b in the figure, the height direction is Figure 1 In the direction indicated by arrow c.

[0030] Specifically, the flip assembly includes a first flip member 41 and a second flip member 42. The first flip member 41 is in the shape of a column, one end of which is arranged on the track 6. The driving assembly can drive the first flip member 41 to reciprocate along the first direction a on the track 6, that is, the first flip member 41 can move from the side of the conveying mechanism 2 to the side of the receiving platform 3 or from the side of the receiving platform 3 to the side of the conveying mechanism 2. The connection between the first flip member 41 and the track 6 can be a sliding connection, that is, a slider (not shown) is provided on the first flip member 41, and a slide groove 61 for the slider to move is provided on the track 6. The slider slides in the slide groove 61 along the track 6 to drive the first flip member 41 to move relative to the track 6, and the driving assembly provides the slider with power to slide on the track 6. The method of connecting the first flip member 41 to the track 6 can also be other, which is not specifically limited here.

[0031] The second flip member 42 is disposed on the first flip member 41, and the driving assembly drives the second flip member 42 to move along the height direction c on the flip member 41. The first flip member 41 is provided with a slideway 411, and the second flip member 42 is provided with a sliding part (not shown), which slides along the slideway 411 to drive the second flip member 42 to move in the height direction c relative to the first flip member 41. The driving assembly provides power for the sliding part to slide on the slideway 411, and the sliding mode of the first flip member 41 and the second flip member 42 can also be other methods, such as a gear rack combination.

[0032] The flip assembly also includes a hooking member 43 for hooking the material and a flipping driving member 44 for driving the hooking member 43 to flip around the axis of the first rotating shaft. The direction of the first rotating shaft is consistent with the second direction b mentioned above. Specifically, the hooking member 43 is arranged on the second flipping member 42 and can be flipped and extended upward in the second direction b relative to the second flipping member 42. In this embodiment, the hooking member 43 flips 180° around the first rotating axis during the process of the first flipping member 41 moving from one side of the conveying mechanism 2 to one side of the receiving table 3. At the same time, the hooking member 43 extends in the direction b, that is, extends relative to the second flipping member 42 and clamps the protective film 12 in the gap. After the material is folded to the receiving table 3, the hooking member 43 can be retracted and flipped to the original position.

[0033] Under the action of the first flip member 41 and the second flip member 42, the hook member 43 can reciprocate in the first direction a and the height direction c. The hook member 43 can be at least partially inserted under the material gap on the conveying mechanism 2 to support the material and leave the conveying mechanism 2, and then fold the material onto the receiving platform 3. In order to increase the connection stability between the hook member 43 and the material, in this embodiment, the hook member 43 is a clamp that can clamp the protective film 12 at least partially in the gap. The structure of the clamp is the prior art and will not be repeated here. Of course, in other embodiments, the hook member 43 can also be other structures, which are not listed here one by one.

[0034] In order to fold the material flat, when folding, the pressing part 5 is located at the first position, pressing on the material to form a fold line, and the first rotation axis is parallel to the fold line and the pressing part 5 is located at the second position when it is away from the material. Figure 1 and Figure 4 One end of the pressing part 5 is pinned to the bracket 1, and the other end can rotate. No matter what position the pressing part 5 is in, it will not affect the movement of the folding mechanism 4 on the track 6. When the pressing part 5 rotates to be parallel to the second direction b, see Figure 4 , reaches the first position, at this time, the pressing part 5 presses on the material and forms a fold line. When the pressing part 5 rotates to be parallel to the first direction a, see Figure 1 It should be noted that, in order to protect the material, the pressing portion 5 presses the protective film 12 at the gap between the light guide plates 11 .

[0035] In order to fold the material smoothly, there are two material folding mechanisms 4, which are relatively arranged on both sides of the conveying mechanism 2. There are two pressing parts 5, which are relatively arranged on both sides of the material. When folding the material, the two material folding mechanisms 4 move synchronously, and the two pressing parts 5 also move synchronously.

[0036] The receiving platform 3 is a rectangular parallelepiped structure. The receiving platform 3 can move up and down relative to the conveying mechanism 2 to adjust the height of the receiving platform 3, so that the height of the material placed on the receiving platform 3 after changing from a flat state to a folded state is equal to the height of the conveying mechanism 2, thereby ensuring that the folding mechanism 4 can work normally and smoothly fold the material from the conveying mechanism 2 to the receiving platform 3. The movement of the receiving platform 3 can be driven by a second driving member (not shown), which can be a motor or a cylinder. A detection member (not shown) for detecting the thickness of the folded material can be installed on the receiving platform 3, and the detection member and the second driving member move under the control of the control mechanism 13. When the material on the receiving platform 3 is higher than the conveying mechanism 2 by a certain value, it is detected by the detection member and fed back to the control mechanism 13, and the control mechanism 13 controls the second driving member to work, thereby driving the receiving platform 3 to descend, so that the height of the folded material placed on the receiving platform 3 is equal to the height of the conveying mechanism 2. Of course, in other embodiments, the detection element may not be provided, and the height to which the material receiving platform 3 needs to descend next time can be calculated by the thickness of the material and the speed at which the material receiving platform 3 folds the material, which is not specifically limited here.

[0037] The continuous lamination device further includes a material pressing mechanism 7 located at one side of the material receiving platform 3. In this embodiment, the material pressing mechanism 7 includes a material pressing frame 71 fixed at one side of the material receiving platform 3, and a material pressing plate 72 disposed on the material pressing frame 71. The material pressing plate 72 can move up and down relative to the material pressing frame 71 to press the folded material located on the material receiving platform 3. In this embodiment, the material pressing plate 72 is slidably connected to the material pressing frame 71, and one end of the material pressing plate 72 can slide downward relative to the material pressing frame 71 to press the material on the material receiving platform 3, and then the material pressing plate 72 slides upward to leave the material receiving platform 3. Of course, in other embodiments, the material pressing plate 72 and the material pressing frame 71 can be rotatably connected, which is not specifically limited here.

[0038] When folding the material, in order to avoid damage such as creases on the material, the first position of the pressing part 5 is located at the gap between two adjacent light guide plates 11, and the hooking member 43 hooks the gap between two adjacent light guide plates 11. The continuous lamination device also includes a detection mechanism 8 located above the conveying mechanism 2, and the detection mechanism 8 is used to detect the gap between the light guide plates 11. In order to avoid the hooking member 43 of the folding mechanism 4 clamping on the light guide plate 11 or the pressing part 5 pressing on the light guide plate 11 to damage the light guide plate 11, it is necessary to confirm that the hooking member 43 clamps the protective film 12 in the gap between the two light guide plates 11, and the pressing part 5 also presses the protective film 12 in the gap between the two light guide plates 11. The detection mechanism 8 is located on one side of the folding mechanism 4, and detects whether the gap between the light guide plates 11 is transported to the clamping position of the hooking member 43 and the first position of the pressing part 5 to ensure that the light guide plates 11 are not damaged. In addition, the detection mechanism 8 can press the material against the conveying mechanism 2. When the hooking member 43 hooks the material and folds the material 11, the detection mechanism 8 moves upward so that the material moves under the detection mechanism.

[0039] The continuous lamination device further comprises a tension wheel set 9 located on the conveying mechanism 2, and the tension wheel set 9 is used to press the material against the conveying mechanism 2. The tension wheel set 9 comprises two tension wheels, which are arranged oppositely on both sides of the detection mechanism 8. When the folding mechanism 4 folds the material, the material is prevented from escaping from the conveying mechanism 2.

[0040] The specific process of the continuous lamination device folding the material once is as follows: Figure 2-Figure 6 First, the pressing part 5 is located at the second position, the second flip member 42 moves downward along the slide 411 on the first flip member 41 to the bottom end of the first flip member 41, and the folding mechanism 4 is located at the initial position; the folding mechanism 4 is located on the side close to the conveying mechanism 2, and there is a light guide plate 11 to be folded between the hooking member 43 and the pressing part 5, and then the hooking member 43 extends out to clamp the gap between the two light guide plates 11, see Figure 2 Then, the pressing plate 72 presses the light guide plate 11 located on the receiving table 3, and the pressing portion 5 moves to the first position, see Figure 3, and pressed against the gap between the two light guide plates 11; then, see Figure 4 and Figure 5 , the first flip member 41 moves along the track 6 in the first direction a, and at the same time the second flip member 42 moves upward relative to the first flip member 41 in the height direction c, the first flip member 41 moves along the track 6 in the direction a, driving the hook member 43 to move toward the receiving platform 3 and fold the light guide plate 11 with the position of the pressing portion 5 as the folding line, at this time, the second flip member 42 first moves upward in the height direction c, and then moves downward, and the hook member 43 rotates 180° around the second flip member at the same time, and the hook member 43 and the light guide plate 11 flip synchronously; see Figure 6 , the first flip member 41 moves to the side of the receiving platform 3, the pressing plate 72 slides upward and leaves the receiving platform 3, and after the light guide plate 11 is folded onto the receiving platform 3, the pressing portion 5 moves to the second position, the hooking member 43 moves in the direction b and retracts to the original position, the pressing plate 72 moves downward onto the receiving platform 3 to press the folded light guide plate 11 onto the receiving platform 3, and the folding of the two light guide plates 11 is completed, and then the folding mechanism 4 moves back to the side of the conveying mechanism 2, and the hooking member 43 rotates around the first rotation axis to the original position, and the operation is repeated to fold the next light guide plate 11. It should be noted that the two folding mechanisms 4 and the two pressing portions 5 move synchronously, and only one folding mechanism 4 or pressing portion 5 is taken as an example here, and when the light guide plate 11 is folded to a certain height, the receiving platform 3 moves downward.

[0041] In summary, the folding mechanism of the continuous lamination device of the present invention can move in space relative to the conveying mechanism, and fold the material on the conveying mechanism onto the receiving table with the pressing portion as the folding line, to ensure that the material is not loose, or squeezed or bent during the folding process. The hooking member for hooking the material flips with the material when folding the material, to ensure that the material will not be folded and damaged. The continuous lamination device of the present invention can fold the material and stack it neatly, thereby improving the stacking efficiency and high yield.

[0042] 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.

[0043] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
