[0046] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0047] Please refer to Figure 1 and Figure 2 , this embodiment provides a film-drawing and cutting device 100, which includes a frame 110, a film-separating assembly 120, a film-drawing assembly 130 and a cutting assembly 140;

[0048] The film separation assembly 120 is connected to the frame 110. The film separation assembly 120 is used to receive the film 10 and separate the film 10 into a top film 11 and a bottom film 12. Specifically, the film separation assembly 120 receives the film 10 from one end, and the top film 11 and the bottom film 12 leave the film separation assembly 120 from two different directions at the other end. The separated top film 11 and the bottom film 12 can be fixed on the film separation assembly 120 and released from the film separation assembly 120 respectively.

[0049] The film drawing assembly 130 includes a top film collecting mechanism connected to the frame 110, a film connecting plate 132 and a driving mechanism 133; the driving mechanism 133 is used to drive one of the film separation assembly 120 and the film connecting plate 132 to reciprocate relative to the frame 110, so that the film separation assembly 120 has a film drawing position and a film tearing position relative to the film connecting plate 132. Specifically, during the reciprocating motion, the end close to the film connecting plate 132 is the film tearing position, and the end away from the film connecting plate is the film drawing position;

[0050] The top film collecting mechanism is used to collect the separated top film 11 . Usually, the top film collecting mechanism is a winding member 131 , and the winding member 131 is used to wind up the top film 11 .

[0051] The film receiving plate 132 is used to receive the bottom film 12 when the film separation assembly 120 is in the film tearing position; the film receiving plate 132 is also used to continuously fix the bottom film 12 separated by the winding member 131 when the film separation assembly 120 moves from the film tearing position to the film pulling position;

[0052] The cutting assembly 140 cuts the bottom film 12 separated from the top film 11 received by the film splicing plate 132. The cutting assembly 140 is arranged on one side of the film splicing plate 132 close to the film drawing position. Specifically, the cutting assembly 140 usually cuts the separated bottom film 12 when the film separation assembly 120 is in the film drawing position.

[0053] When the film receiving plate 132 receives the base film 12 , the base film 12 is laid flat and fixed on the film receiving plate 132 .

[0054] It should be noted that, in this embodiment, the film 10 is described as a double-layer film as an example; in other embodiments of the present invention, the film layer of the film 10 may also be more than two layers.

[0055] Please refer to Figure 1 and Figure 2 The working process of the film drawing and cutting device 100 is:

[0056] The film-drawing and cutting device 100 comprises a frame 110, a film-splitting assembly 120, a film-drawing assembly 130 and a cutting assembly 140; the film-splitting assembly 120 is connected to the frame 110, and is used to receive a film 10 and separate the two-layer film 10 into a top film 11 and a bottom film 12. Specifically, the film-splitting assembly 120 receives the film 10 from one end, and the top film 11 and the bottom film 12 leave the film-splitting assembly 120 from two different directions at the other end. The top film 11 and the bottom film 12 separated by the film-splitting assembly 120 can be fixed on the film-splitting assembly 120 and released from the film-splitting assembly 120 respectively; wherein the separated top film 11 is rolled up into a rolling member 131, and the separated bottom film 12 is received by a film-joining plate 132;

[0057] Specifically, under the driving action of the driving mechanism 133, one of the film separating assembly 120 and the film connecting plate 132 will reciprocate relative to the frame 110, so that the film separating assembly 120 has a film pulling position and a film tearing position relative to the film connecting plate 132. Specifically, when the film separating assembly 120 reciprocates, the end close to the film connecting plate 132 is the film tearing position, and the end away from the film connecting plate is the film pulling position; and when the film separating assembly 120 is in the film tearing position, the film separating assembly 120 releases the fixation of the separated bottom film 12, which begins to be received and fixed by the film connecting plate 132 in a flat manner; the film separating assembly 120 releases the fixation of the separated top film 11, and as the film separating assembly 120 moves from the film tearing position to the film pulling position under the driving action of the driving mechanism 133, the winding member 131 will continuously wind up the separated top film 11, and at this During the process, the separated bottom film 12 is continuously fixed by the film connecting plate 132; that is, when the film separating component 120 is located at the film tearing position, the process from the film separating component 120 moving to the film drawing position is a continuous film drawing step, and the process of the film connecting plate 132 fixing the bottom film 12 is continuous, so that the received bottom film 12 is laid flat on the film connecting plate 132 to avoid wrinkles in the bottom film 12; and after the film separating component 120 is located at the film drawing position, the film drawing step is completed, and the bottom film 12 received by the film connecting plate 132 can be cut by the cutting component 140; during the cutting process, the preferred film separating component 120 fixes the top film 11 and the bottom film 12. In this way, during the cutting process, the two sides of the cutting position are respectively fixed by the film connecting plate 132 and the film separating component 120, so that cutting can be more convenient and neat.

[0058] In summary, in the process of the film drawing and cutting device 100 moving the film 10 from the film drawing position to the film tearing position, the separated top film 11 and bottom film 12 are fixed on the film separation component 120, and are synchronously fixed with the unseparated film 10 and sent to the film tearing position. In the process of film drawing, the bottom film 12 (including the separated and unseparated bottom films) is fixed by the film connection plate 132, and then the unseparated bottom film is released by the relative movement between the film separation component 120 and the film connection plate 132. The top film 11 and the bottom film 12 are separated into a film 10, and the top film 11 is rolled up by the winding member 131 so that the released film 10 is continuously separated from one side of the film connecting plate 132 to the other side. The bottom film 12 is continuously fixed by the film connecting plate 132, so that the bottom film 12 can be kept flat on the film connecting plate 132, so as to effectively avoid wrinkles in the film 10 during the film feeding process, thereby effectively improving the processing accuracy of the pattern and improving the yield rate of the film 10 processing.

[0059] During the film drawing process, the part of the film 10 that has not been separated is released through the relative movement between the film separation component 120 and the film connecting plate 132, and the film 10 is separated by the winding top film 11 of the winding member 131. Therefore, in order to enable relative movement between the film separation component 120 and the film connecting plate 132, the driving mechanism 133 can be used to drive the film separation component 120 to move relative to the frame 110, or the driving mechanism 133 can be used to drive the film connecting plate 132 to move relative to the frame 110; in the present embodiment, the film separation component 120 and the frame 110 are movably connected, and the driving mechanism 133 is used to drive the film separation component 120 to move relative to the frame 110.

[0060] Based on the above content, the film separation component 120 has a film drawing position and a film tearing position relative to the film connection plate 132 under the action of the driving mechanism 133; therefore, during the operation of the film drawing and cutting device 100, the driving mechanism 133 is used to drive the film separation component 120 to change the position between the film tearing position and the film drawing position relative to the film connection plate 132, and the position change method is that the film connection plate 132 reciprocates between the film tearing position and the film drawing position, so that in this way, film drawing and film cutting can be cyclically performed, thereby improving the work efficiency; therefore, during the film drawing process of the film drawing and cutting device 100, its single cycle process is as follows:

[0061] At the beginning, the initial position of the film separation component 120 is at the film pulling position. At this time, the film 10 is transported into the film separation component 120 and begins to separate the top film 11 and the bottom film 12. At this time, the film separation component 120 can play a role in positioning and fixing the separated top film 11 and the bottom film 12 respectively, so as to facilitate pushing the separated bottom film 12 to the film receiving plate 132 and fixing the top film 11. In the subsequent movement to the film tearing position, the positions of the top film 11, the bottom film 12 and the unseparated film 10 are fixed to avoid misalignment of the three, resulting in wrinkles on the top film 11 or the bottom film 12.

[0062] Subsequently, the film separation assembly 120 moves to the film tearing position, at which time the bottom film 12 in the film separation assembly 120 is pushed to the film receiving plate 132, and after being pushed, the film receiving plate 132 collects and fixes the bottom film 12 separated from the film separation assembly 120; it should be noted that the film receiving plate 132 collects and fixes the bottom film 12 that has been separated and the film 10 that has not been separated and is waiting to be torn;

[0063] Then, the film separation assembly 120 releases the fixation of the bottom film 12 and the top film 11 and moves to the film pulling position. During this process, the top film 11 is rolled up by the rolling element 131, so that the film 10 is continuously separated, and the separated bottom film 12 is continuously fixed by the film connection plate 132.

[0064] Finally, the bottom film 12 collected by the film connecting plate 132 can be cut from the side of the film connecting plate 132 close to the film drawing position by the cutting component 140, thereby completing a single cycle. During this process, the film separating component 120 fixes the top film 11 and the bottom film 12 to ensure the cutting effect, and at this time the film separating component 120 is located in the film drawing position, that is, it can start to enter the next film drawing step.

[0065] It should also be noted that the size of the cut monomer base film 12 will be affected by the area of ​​the base film 12 that the film connecting plate 132 is used to receive and fix. Therefore, when setting the film connecting plate 132, in order to avoid wrinkles on the base film 12, it is necessary to determine the area of ​​the base film 12 that the film connecting plate 132 is used to receive and fix according to processing requirements; in addition, the size of the cut monomer base film 12 can be adjusted by adjusting the relative movement distance between the film separation component 120 and the film connecting plate 132, that is, it can be adjusted by adjusting the spacing between the film tearing position and the film pulling position, that is, a base film 12 larger than the area of ​​the film connecting plate 132 for receiving the base film 12 can be cut. However, generally speaking, in order to keep the base film 12 flat, the cutting component 140 is usually set at a position close to the film connecting plate 132, and the cut monomer base film 12 is a flat, wrinkle-free base film that is always fixed to the film connecting plate 132.

[0066] Based on the above structure settings, please refer to Figure 1 and Figure 2 In this embodiment, when the driving mechanism 133 is set, the driving mechanism 133 includes a driving motor, a first driving wheel, a second driving wheel and a transmission belt. The first driving wheel and the second driving wheel are arranged at intervals, and the transmission belt is sleeved on the first driving wheel and the second driving wheel. The driving motor is connected to the first driving wheel or the second driving wheel in a transmission manner; the film separation component 120 is connected to the transmission belt in a transmission manner. Therefore, through such a setting, the first driving wheel or the second driving wheel can be driven by the driving motor to rotate, which can drive the transmission belt to move, and then drive the film separation component 120 to move. Therefore, in this embodiment, through the belt transmission method, the film tearing position and the film pulling position are relatively located between the positions of the first driving wheel and the second driving wheel; that is, a cycle can be formed through the unidirectional rotation of the driving motor, and a cycle can also be formed through the bidirectional rotation of the driving motor, thereby improving the work efficiency; and in other embodiments of the present invention, different from the aforementioned belt transmission method, when the driving mechanism 133 is set, a screw driving mechanism or a gear driving mechanism can also be used.

[0067] For further information, please refer to Figure 1 and Figure 2In this embodiment, when the film separation assembly 120 is set, the film separation assembly 120 includes a wedge block 121, a first positioning block 122 and a second positioning block 123; wherein the wedge block 121 is used to receive the film 10 and separate the film 10 into a top film 11 and a bottom film 12; the first positioning block 122 and the second positioning block 123 are used to limit the movement of the top film 11 and the bottom film 12 separated by the wedge block 121 relative to the wedge block 121. It should be noted that the film 10 is introduced into the film separation assembly 120 by releasing it through the unwinding mechanism.

[0068] Therefore, through such a setting, the film 10 can be separated by the wedge block 121, and the first positioning block 122 and the second positioning block 123 respectively limit the movement of the top film 11 and the bottom film 12 separated by the wedge block 121 relative to the wedge block 121. The purpose is that when the film separation assembly 120 moves from the film pulling position to the film tearing position under the action of the driving mechanism 133, it can play a role in positioning and fixing the top film 11 and the bottom film 12, ensuring that the positions of the separated top film 11 and the bottom film 12 relative to the wedge block 121 remain unchanged, so as to avoid wrinkles on the top film 11 and the bottom film 12 during this process, and at the same time facilitate the subsequent pushing of the bottom film 12.

[0069] When the structure of the aforementioned film separation component 120 is adopted, the film connecting plate 132 can be set below the film separation component 120; and the film 10 introduced into the film separation component 120 contacts the lower end of the wedge block 121, and the lower end of the wedge block 121 is horizontal, that is, the contact surface of the film 10 and the wedge block 121 is horizontal, and the wedge end of the wedge block 121 is set toward the film tearing position, and the top film 11 and the bottom film 12 are separated at the wedge end, and the top film 11 passes over the top of the wedge block 121 and is wound on the winding member 131; and when setting the first positioning block 122 and the second positioning block 123, the first positioning block 122 can be set above the wedge block 121, and the fixed surface of the second positioning block 123 for contacting the bottom film 12 is parallel to the contact surface of the wedge block 121 for contacting the film 10, and the second positioning block 123 is located on the side of the wedge block 121 close to the film tearing position. Therefore, through such an arrangement, when the film separation assembly 120 moves from the film pulling position to the film tearing position, the second positioning block 123 is relatively located in front of the moving direction of the wedge block 121, so as to facilitate pushing the separated bottom film 12 to the film receiving plate 132.

[0070] Furthermore, in the present embodiment, the film separating assembly 120 also includes a first driving part, and the first positioning block 122 is movably connected to the wedge block 121, and the first driving part is used to drive the first positioning block 122 to move relative to the wedge block 121, so as to press the top film 11 separated by the wedge block 121 when the wedge block 121 is in the film pulling position, the wedge block 121 moves from the film pulling position to the film tearing position, and during cutting, to achieve the fixation of the top film 11 by the film separating assembly 120, and when the wedge block 121 moves from the film tearing position to the film pulling position, it moves away from the wedge block 121, so that the top film 11 can pass through the gap between the first positioning block 122 and the wedge block 121 and be wound up by the winding member 131; and in other embodiments of the present invention, the first positioning block 122 can also be provided with a first film suction part connected to an external vacuum adsorption mechanism, the first film suction part adsorbs the top film 11 separated by the wedge block 121 to achieve the fixation of the top film 11 by the film separating assembly 120, and releases the adsorption to release the fixation of the top film 11. It should be noted that, when such a setting is adopted, the first positioning block 122 and the wedge block 121 are made in one piece, and a gap is set between the first positioning block 122 and the wedge block 121 for the top film 11 to pass through. In another embodiment, the first positioning block 122 is set on the wedge block 121, for example, on the top of the wedge block 121. It can be understood that the separated top film 11 is wound around the first positioning block 122, and the top film 11 is vacuum-adsorbed on the side contacting the first positioning block 122, so as to fix the top film 11.

[0071] In addition, the film separating assembly 120 also includes a second driving part, and the second positioning block 123 is movably connected to the wedge block 121, and the second driving part is used to drive the second positioning block 123 to move up and down relative to the wedge block 121 to push the bottom film 12 separated by the wedge block 121 to the film connecting plate 132; the second positioning block 123 is provided with a second film absorbing part connected to an external vacuum adsorption mechanism at the bottom, and the second film absorbing part is used to absorb the bottom film 12 separated by the wedge block 121 when the wedge block 121 is in the film pulling position, the wedge block 121 moves from the film pulling position to the film tearing position, and the second positioning block 123 pushes the bottom film 12 toward the film connecting plate 132, so as to fix the bottom film 12 by the film separating assembly 120, and release the adsorption to release the fixation of the bottom film 12 when the film connecting plate 132 fixes the bottom film 12 and the wedge block 121 moves from the film tearing position to the film pulling position. Thus, through the above-mentioned setting method, the position of the bottom film 12 relative to the wedge block 121 can be fixed according to the use requirements during the film drawing process, so as to avoid wrinkles. At the same time, the second driving unit is used to drive the second positioning block 123 to move up and down relative to the wedge block 121. When the wedge block 121 is in the film drawing position and the wedge block 121 moves from the film drawing position to the film tearing position, the driving unit drives the second film suction part of the second positioning block 123 to be coplanar with the lower end of the wedge block, so as to avoid the misalignment of the separated bottom film 12 and the unseparated film 10 during the movement process, resulting in wrinkles; when the wedge block 121 reaches the film tearing position, the second driving unit drives the second positioning block 123 to move downward to the film connection plate 132 to push the bottom film 12, and after the film connection plate 132 fixes the bottom film 12, the second film suction part is released, and then drives the second positioning block 123 to move upward until its second film suction part reaches a position not lower than the lower end of the wedge block 121.

[0072] Based on the above content, it can be known that in the present embodiment, when the film receiving plate 132 is set, its function is to receive the separated base film 12, so that the base film 12 can be fixed to avoid wrinkles in the process of pulling the film; based on this, in order to make the base film 12 be laid flat on the film receiving plate 132 when the film receiving plate 132 adsorbs the base film 12, the film receiving plate 132 is provided with a third film adsorption part connected to an external vacuum adsorption mechanism, and the third film adsorption part is used to adsorb the base film 12. It should be noted that, from the above content, it can be seen that in the present embodiment, the film separation assembly 120 separates the bottom film 12 and the top film 11 of the film 10 by means of a second driving unit driving the second positioning block 123 to move relative to the wedge block 121, so as to push the bottom film 12 separated by the wedge block 121 to the film connecting plate 132; and in other embodiments of the present invention, the film connecting plate 132 can also be moved relative to the wedge block 121 so that the wedge block 121 can move in a direction away from or close to the wedge block 121, thereby replacing the bottom film 12 pushing effect formed by the second positioning block 123 under the action of the second driving unit.

[0073] Generally, in order to avoid wrinkles, the length of the bottom film 12 separated before tearing the film should be as short as possible, so that more bottom film 12 can be separated on the film connection plate 132. Therefore, the area of ​​the second positioning block 123 should be much smaller than the film connection plate 132. Preferably, the width of the fixed end of the second positioning block is, for example, about 10 mm.

[0074] For further information, please refer to Figure 1 and Figure 2 When setting the cutting assembly 140, the cutting assembly 140 used in this embodiment includes a cutter 141 and at least one third driving part 142 connected to the frame 110; the cutter 141 is connected to the third driving part 142, and the third driving part 142 is used to drive the cutter 141 to move so as to cut the bottom film 12 collected by the film receiving plate 132. It should be noted that during the cutting process, the cutter 141 can be driven to move in one direction or multiple directions by one or more third driving parts 142, so as to achieve different forms of cutting to meet the needs of use; that is, the cutting method of the cutter can be multiple, and horizontal cutting, vertical cutting or laser cutting can meet the requirements.

[0075] Generally, in order to avoid wrinkles, before cutting, the bottom film 12 outside the film-joining plate 132 should be as small as possible to avoid wrinkles caused by cutting stress. Therefore, the distance between the cutting end of the cutting assembly 140 and the film-joining plate 132 can be about 8 mm.

[0076] It should be noted that, in the above content, the first film suction part, the second film suction part and the third film suction part all adopt a channel structure, the purpose of which is to enable the external vacuum adsorption mechanism to play the role of adsorbing the top film 11 or the bottom film 12; and the above-mentioned first driving part, the second driving part and the third driving part 142 can be driven by cylinders, hydraulic cylinders or linear motors.

[0077] In summary, please refer to Figure 1-Figure 5 The working steps of the film drawing and cutting device 100 are as follows:

[0078] Please refer to Figure 3 At the beginning, the film separation assembly 120 is in the film pulling position, and the film 10 released by the unwinding mechanism is introduced into the film separation assembly 120; specifically, the film 10 passes under the wedge block 121, and the film 10 starts to separate from the wedge end, and the separated top film 11 passes through the gap between the first positioning block 122 and the wedge block 121 and is rolled up in the winding member 131, while the bottom film 12 is adsorbed by the second positioning block 123;

[0079] Subsequently, the first positioning block 122 moves toward the wedge block 121 under the action of the first driving unit, and clamps the separated top film 11 together with the wedge block 121. At the same time, the fixed end of the second positioning block 123 and the contact end of the wedge block 121 are coplanar, and the bottom film 12 is kept adsorbed.

[0080] Then, please refer to Figure 3-Figure 4 , the driving mechanism 133 drives the film separation assembly 120 to move from the film pulling position toward the film tearing position. After moving to the film tearing position, the second positioning block 123 pushes the separated bottom film 12 toward the film connecting plate 132 under the action of the second driving unit; and after the bottom film 12 is adsorbed by the film connecting plate 132, the second positioning block 123 cancels the adsorption effect on the bottom film 12, and moves in the direction away from the film connecting plate 132 under the action of the second driving unit; the first positioning block 122 releases the clamped top film 11 under the action of the first driving unit; thus, the separated bottom film 12 is received on the film connecting plate 132, and is adsorbed and fixed under the action of the third film suction part on the film connecting plate 132, and the bottom film 12 is in a flat state; Figure 4 A schematic diagram showing a state in which the first positioning block 122 releases the top film and the bottom film 12 is laid flat on the film connection plate 132;

[0081] Then, the driving mechanism 133 drives the film separation assembly 120 to move from the film tearing position toward the film pulling position. During this process, under the action of the winding member 131, the top film 11 and the bottom film 12 are continuously separated, and the separated top film 11 is wound into the winding member 131, while the separated bottom film 12 is always adsorbed and fixed by the film receiving plate 132 during this process until the film separation assembly 120 moves to the film pulling position.

[0082] Please refer to Figure 5 The first positioning block 122 moves toward the wedge block 121 under the action of the first driving unit, and clamps the top film 11 together with the wedge block 121, while the bottom film 12 is adsorbed by the second positioning block 123; the third driving unit 142 drives the cutter 141 to cut the bottom film 12 received by the film receiving plate 132 and the bottom film 12 adsorbed by the second positioning block 123; Figure 5 The bottom film 12 is shown cut;

[0083] Repeat the above actions to complete the next film pulling, film tearing and cutting.

[0084] It should be noted that in order to improve work efficiency, the film drawing and cutting device 100 can also include a base film 12 transfer component, which can be a negative pressure adsorption robot, which is used to adsorb the base film 12 segments formed by cutting on the film receiving plate 132 and move them out of the film receiving plate 132.

[0085] The film drawing and cutting device 100 has the following advantages:

[0086] The problem of wrinkles in the film 10 during the film drawing and feeding process is solved, and the processing accuracy and product yield are effectively improved; the double-layer film is peeled off and separated during the film drawing process, the structure is compact, and equipment space is saved; the film is cut into single pieces for processing, which further improves the processing accuracy; the movements of each structure are independent of each other, the structure is simple, and maintenance is convenient.

[0087] It should be noted that Figures 3 to 5 This is a schematic diagram showing the film drawing and cutting process of the film drawing and cutting device 100. As can be understood by those skilled in the art, there is no interference between the components in the device.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
