Description

Technical Field

[0001] This application relates to the field of photovoltaic cell string production, specifically a film strip cutting mechanism and a film strip preparation device. Background Technology

[0002] In the production of battery strings, membrane strips are required. Existing membrane strip preparation equipment typically uses multiple cutters to simultaneously cut the membrane sheet to obtain multiple membrane strips. Specifically, the membrane sheet is placed horizontally on a support platform, the blades of each cutter extend vertically, and the support surface of the platform is provided with a relief groove corresponding to each cutter. Each cutter extends into its corresponding relief groove and moves from one end of the membrane sheet to the other end, thereby performing the cutting of the membrane sheet.

[0003] Because the blades of each cutter cut the diaphragm vertically, they experience greater cutting resistance, making it easier for debris to form. Furthermore, the cutting resistance varies depending on the material and thickness of the diaphragm, making it difficult to control the cutting quality of different diaphragms. Utility Model Content

[0004] To address the aforementioned technical problems, this application first provides a film strip slitting mechanism, the detailed technical solution of which is as follows:

[0005] A film strip slitting mechanism includes a mounting frame, a first lifting drive unit, a support frame, a translation drive unit, a connecting bracket, a connecting plate, a blade holder, and a plurality of cutters, wherein:

[0006] The first lifting drive unit is mounted on the mounting bracket;

[0007] The support frame is connected to the movable part of the first lifting drive unit;

[0008] The connecting bracket is slidably connected to the support frame and is connected to the translation drive unit provided on the support frame;

[0009] The mounting angle of the connecting plate on the connecting bracket is adjustable;

[0010] The blade holder is connected to the connecting plate, and several cutters are arranged side by side at intervals on the blade holder. The angle between the blade edge of the cutter and the horizontal plane changes with the installation angle of the connecting plate, and the angle between the blade edge of the cutter and the horizontal plane is less than 90°.

[0011] The first lifting drive unit is configured to drive the support frame to lift so that each cutter moves closer to or further away from the film to be cut;

[0012] The translation drive unit is configured to drive the connecting bracket to reciprocate and translate, thereby driving each cutter to cut the membrane into several membrane strips.

[0013] The membrane strip slitting mechanism provided in this application has a blade holder equipped with a cutter mounted on a connecting plate. The mounting angle of the connecting plate on the connecting bracket is adjustable. By adjusting the mounting angle of the connecting plate, the tilt angle of the cutter can be adjusted. The angle between the blade of the cutter and the horizontal plane can be adjusted arbitrarily within a range of less than 90°. Thus, on the one hand, the blade of the cutter can slit the membrane in a tilted state, thereby reducing resistance and reducing the generation of debris. On the other hand, for membranes of different materials or thicknesses, the tilt angle of the cutter can be adjusted to a suitable position according to the actual cutting resistance, thereby achieving control over the cutting quality of different membranes.

[0014] In some embodiments, the connecting bracket includes a first side plate and a second side plate that are connected to each other and disposed opposite to each other, wherein: the first side plate and the second side plate are slidably connected to the support frame and are drivenly connected to the translation drive unit; a connecting plate is disposed between the first side plate and the second side plate, and both ends of the connecting plate are rotatably connected to the first side plate and the second side plate respectively through a horizontally disposed first rotating shaft, and at least one end of the connecting plate is also connected to the first side plate and / or the second side plate through an angle adjustment structure.

[0015] The connecting bracket includes a first side plate and a second side plate arranged opposite to each other, and the first side plate and the second side plate are slidably connected to the support frame, which improves the stability of the connecting bracket and ensures that the connecting bracket can slide smoothly under the drive of the translation drive unit, avoiding tilting or jamming during the sliding process. The two ends of the connecting plate are rotatably connected to the first side plate and the second side plate respectively through a first rotating shaft, ensuring that the connecting plate can rotate stably when the angle adjustment structure is implemented, avoiding tilting or jamming during the rotation process.

[0016] In some embodiments, the angle adjustment structure includes a connecting block, a bolt, and arc-shaped connecting holes respectively provided on the first side plate and the second side plate; a connecting block is fixedly connected to each end of the connecting plate, one connecting block is rotatably connected to the first side plate via a first rotating shaft, and the other connecting block is rotatably connected to the second side plate via a first rotating shaft, and at least two threaded holes are provided on each connecting block at the position corresponding to the connecting hole on the same side; after the two connecting blocks rotate to their respective first rotating shafts, the first side plate and the connecting block on the same side are fixedly connected by bolts passing through the connecting holes and the threaded holes, and the second side plate and the connecting block on the same side are fixedly connected by bolts passing through the connecting holes and the threaded holes.

[0017] A simple and easy-to-adjust manual angle adjustment structure is provided. When the angle of the connecting plate needs to be adjusted, first loosen the corresponding bolts on the two connecting blocks, and then push the connecting plate to rotate. After the connecting plate rotates to the correct position, tighten the bolts on the two connecting blocks again to re-fix the two connecting blocks to the first and second side plates.

[0018] In some embodiments, the film strip slitting mechanism further includes a vibration mechanism; the vibration mechanism is disposed on the connecting plate and drivenly connected to the blade holder, and the vibration mechanism is configured to drive each cutter on the blade holder to reciprocate along the length of the blade.

[0019] During the slitting process of the membrane, the vibration mechanism drives each cutter on the cutter holder to vibrate back and forth along the length of the blade. This can effectively reduce the continuous friction force experienced by the cutter during cutting, thereby further improving the slitting effect of the membrane and obtaining membrane strips with straighter edges.

[0020] In some embodiments, the vibration mechanism includes a driver, a second rotating shaft, two eccentric wheels, and two lifting blocks. The driver is mounted on a connecting plate, the second rotating shaft is horizontally arranged and drivenly connected to the driver, and an eccentric wheel is connected to each end of the second rotating shaft. The two lifting blocks are respectively arranged on both sides of the second rotating shaft and are slidably connected to the connecting plate in a direction perpendicular to the connecting plate. The blade holder is fixedly connected to the two lifting blocks, and the lifting blocks are provided with waist holes. The two eccentric wheels are respectively located in the waist holes of the lifting blocks on the same side. The driver is used to drive the second rotating shaft to rotate around the axial direction, so as to drive the lifting blocks to slide back and forth via the eccentric wheels. The length direction of the blade is the same as the sliding direction of the lifting blocks.

[0021] With this setup, during the slitting process of the film, the driver drives the second rotating shaft to rotate, which in turn causes the lifting block to slide back and forth, thereby causing the cutter to vibrate back and forth along the length of its blade.

[0022] In some embodiments, the two lifting blocks are also buoyantly connected to the connecting plate via springs.

[0023] The lifting blocks are buoyantly connected to the connecting plate via springs. This allows the two lifting blocks to slide back and forth under the drive of the eccentric wheel. Furthermore, it reduces structural resonance, ensuring that the tangential surfaces of the eccentric wheel and the waist holes within the lifting blocks are tightly fitted, preventing frequency mismatch during vibration and thus preventing the eccentric wheel from shifting.

[0024] This application also provides a film strip preparation apparatus, which includes a support platform, a film pressing plate, and a film strip slitting mechanism as described in any one of the above claims, wherein:

[0025] The support platform is used to support the film to be cut. The support surface of the support platform is set horizontally, and several long strip-shaped knife grooves are arranged side by side at intervals on the support surface of the support platform.

[0026] The film strip slitting mechanism is located above the support platform. The pressure plate is horizontally set between the film strip slitting mechanism and the support platform. The pressure plate has several slitting slits that run from top to bottom through the pressure plate. The slitting slits, the knife grooves, and the cutters are set one by one.

[0027] The pressure plate is configured to press the film to be cut onto the support table;

[0028] The cutter is used to cut the membrane into several strips by passing downward through the slitting slit and extending into the cutter groove, and moving along the length of the cutter groove.

[0029] By coordinating the support platform, the pressure plate, and the film strip slitting mechanism, the film strip preparation apparatus of this application achieves automatic slitting of the film sheets. In particular, by adjusting the angle of the cutter of the film strip slitting mechanism, the blade can be tilted to slit the film sheets on the support platform, thereby reducing resistance and minimizing debris generation. On the other hand, for film sheets of different materials or thicknesses, the tilt angle of the cutter can be adjusted to a suitable position according to the actual cutting resistance, thereby achieving control over the cutting quality of different film sheets.

[0030] In some embodiments, the film strip preparation apparatus further includes a second lifting drive unit, a film pressing plate is connected to a movable part of the second lifting drive unit, the second lifting drive unit is configured to drive the film pressing plate to lift, and a flexible pad is covered on the bottom surface of the film pressing plate.

[0031] Because the cutting blade of the film strip slitting mechanism is raised and lowered by the first lifting drive unit, while the pressure plate is raised and lowered by the second lifting drive unit, the cutting blade and the pressure plate can be raised and lowered independently without interference. This configuration achieves the following technical effects: First, the pressure force of the pressure plate on the film can be independently controlled, unaffected by the current position of the cutting blade. The installation angle of the cutting blade can also be independently adjusted, unaffected by the current position of the pressure plate. Second, the relative position of the cutting blade and the pressure plate can be flexibly adjusted, allowing for flexible adjustment of the length of the cutting blade extending downwards from the pressure plate. Thus, when the blade segment currently used for cutting the film becomes dull, adjusting the relative position of the cutting blade and the pressure plate allows the other, undulled blade segment to cut the film, thereby extending the cutting blade's service life.

[0032] Because the bottom surface of the pressure plate is covered with a flexible pad, the pressure plate can flexibly press the film onto the support platform, ensuring that the film can be pressed onto the support platform from all directions, ultimately improving the slitting effect of the film.

[0033] In some embodiments, the second lifting drive unit includes two lifting drive assemblies arranged opposite to each other. Each lifting drive assembly includes a fixed frame, a movable frame, and a lifting drive component. The fixed frame is fixedly arranged, and the movable frame is longitudinally movable and connected to the fixed frame and connected to the drive end of the lifting drive component arranged on the fixed frame. The two ends of the pressure plate are respectively connected to the two movable frames.

[0034] Two opposing lifting drive components synchronously drive the pressure plate to rise and fall from both ends, ensuring that the pressure plate rises and falls stably in a horizontal state, ultimately improving the pressing effect of the pressure plate on the film.

[0035] In some embodiments, the film strip preparation apparatus further includes a first moving part and a conveying mechanism, wherein a support platform is connected to a movable part of the first moving part, and the support platform is provided with adsorption holes for adsorbing film sheets; the first moving part is used to drive the support platform to reciprocate between a film bonding station and a slitting station; the conveying mechanism is movable to the film bonding station, and a film pressing plate and a film strip slitting mechanism are disposed at the slitting station; the conveying mechanism is configured to lay the film sheet to be slitted onto the support platform located at the film bonding station; the film pressing plate and the film strip slitting mechanism are configured to press and slit the film sheet moved to the support platform at the slitting station.

[0036] Driven by the first moving part, the carrier platform can reciprocate between the film splicing station and the slitting station. When the carrier platform switches to the film splicing station, the transport mechanism can lay the film to be slitted onto the carrier platform located at the film splicing station, avoiding interference with the film pressing plate and film strip slitting mechanism. When the carrier platform switches to the slitting station, it can cooperate with the film pressing plate and film strip slitting mechanism to perform normal slitting of the film.

[0037] The support platform can hold the membrane sheet and the membrane strips obtained after slitting through its adsorption holes, preventing the membrane sheet and membrane strips from shifting during movement. Attached Figure Description

[0065] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0066] As described in the background section, current membrane strip slitting mechanisms experience significant cutting resistance due to the vertical cutting blade position, leading to the formation of debris. Furthermore, the cutting resistance varies depending on the membrane material and thickness, making it difficult to control the cutting quality of different membranes. To address this issue, this application provides a membrane strip slitting mechanism.

[0067] like Figures 1 to 6 As shown, the film strip slitting mechanism 10 provided in this application includes a mounting frame 1, a first lifting drive unit 2, a support frame 3, a translation drive unit 4, a connecting bracket 5, a connecting plate 6, a blade holder 7, and a plurality of cutting blades 8, wherein:

[0068] The first lifting drive unit 2 is mounted on the mounting bracket 1.

[0069] The support frame 3 is connected to the movable part of the first lifting drive unit 2.

[0070] The connecting bracket 5 is slidably connected to the support frame 3 and is connected to the translation drive unit 4 provided on the support frame 3.

[0071] The mounting angle of the connecting plate 6 on the connecting bracket 5 is adjustable.

[0072] The blade holder 7 is connected to the connecting plate 6. Several cutters 8 are arranged side by side at intervals on the blade holder 7. The angle between the blade 81 of the cutter 8 and the horizontal plane changes with the installation angle of the connecting plate 6, and the angle between the blade 81 of the cutter 8 and the horizontal plane is less than 90°.

[0073] The first lifting drive unit 2 is configured to drive the support frame 3 to lift, so that each cutter 8 moves closer to or further away from the film to be cut.

[0074] The translation drive unit 4 is configured to drive the connecting bracket 5 to reciprocate, thereby driving each cutter 8 to cut the membrane into several membrane strips.

[0075] The film strip slitting mechanism 10 provided in this application has a blade holder 7 equipped with a cutter 8 mounted on a connecting plate 6. The mounting angle of the connecting plate 6 on the connecting bracket 5 is adjustable. By adjusting the mounting angle of the connecting plate 6, the tilt angle of the cutter 8 can be adjusted. The angle between the blade 81 of the cutter 8 and the horizontal plane can be arbitrarily adjusted within a range of less than 90°. Thus, on the one hand, the blade 81 of the cutter 8 can slit the film in a tilted state, thereby reducing resistance and the generation of debris. On the other hand, for film strips of different materials or thicknesses, the tilt angle of the cutter 8 can be adjusted to a suitable position according to the actual cutting resistance, thereby achieving control over the cutting quality of different film strips.

[0076] Both the first lifting drive unit 2 and the translation drive unit 4 can adopt various existing linear drive modules, such as a screw drive module consisting of a motor, a lead screw, and a lead screw nut, or a belt drive module consisting of a motor, a pulley, and a belt.

[0077] like Figure 2 As shown, optionally, the connecting bracket 5 includes a first side plate 51 and a second side plate 52 that are interconnected and arranged opposite to each other. The first side plate 51 and the second side plate 52 are slidably connected to the support frame 3 and are drively connected to the translation drive unit 4. A connecting plate 6 is disposed between the first side plate 51 and the second side plate 52. Both ends of the connecting plate 6 are rotatably connected to the first side plate 51 and the second side plate 52 via horizontally arranged first rotating shafts 112. Both ends of the connecting plate 6 are connected to the first side plate 51 and the second side plate 52 via angle adjustment structures 11. Alternatively, the connecting plate 6 may be connected to either the first side plate 51 or the second side plate 52 at only one end via the angle adjustment structure 11.

[0078] By configuring the connecting bracket 5, the connection stability between the connecting bracket 5 and the support frame 3 is improved, ensuring that the connecting bracket 5 slides smoothly on the support frame 3 under the drive of the translation drive unit 4, and preventing the connecting bracket 5 from tilting or jamming during the sliding process. The two ends of the connecting plate 6 are rotatably connected to the first side plate 51 and the second side plate 52 respectively via the first rotating shaft 112, ensuring that the connecting plate 6 can rotate stably when the angle is adjusted, and preventing the connecting plate 6 from tilting or jamming during rotation.

[0079] Furthermore, since at least one end of the connecting plate 6 is connected to the first side plate 51 and / or the second side plate 52 via the angle adjustment structure 11, the connecting plate 6 can be rotated by the angle adjustment structure 11 to adjust the angle of the connecting plate 6.

[0080] like Figures 2 to 6As shown, optionally, the angle adjustment structure 11 includes a connecting block 111, bolts (not shown in the figure), and arc-shaped connecting holes 113 respectively provided on the first side plate 51 and the second side plate 52. A connecting block 111 is fixedly connected to each end of the connecting plate 6. One connecting block 111 is rotatably connected to the first side plate 51 via a first rotating shaft 112, and the other connecting block 111 is rotatably connected to the second side plate 52 via the first rotating shaft 112. Each connecting block 111 has at least two screw holes 114 at positions corresponding to the connecting holes 113 on the same side. After the two connecting blocks 111 rotate around their respective first rotating shafts 112 to their positions, the first side plate 51 is fixedly connected to the connecting block 111 on the same side by bolts passing through the connecting holes 113 and the screw holes 114, and the second side plate 52 is fixedly connected to the connecting block 111 on the same side by bolts passing through the connecting holes 113 and the screw holes 114.

[0081] Specifically, when it is necessary to adjust the angle of the connecting plate 6, first loosen the corresponding bolts on the two connecting blocks 111, and then manually push the connecting plate 6 to rotate. After the connecting plate 6 is rotated into place, tighten the bolts on the two connecting blocks 111 again, so that the two connecting blocks 111 are re-fixed to the first side plate 51 and the second side plate 52.

[0082] Of course, in other embodiments, the angle of the connecting plate 6 can also be adjusted in other ways.

[0083] For example, in another embodiment, the angle adjustment structure includes a servo motor that is connected to the connecting plate 6 via a transmission connection. The servo motor drives the connecting plate 6 to rotate, thereby adjusting the angle of the connecting plate 6.

[0084] For example, in another embodiment, the angle adjustment structure includes a first gear and a second gear. The first gear is installed on the first rotating shaft 112 at one end of the connecting plate 6. The first gear meshes with the second gear. By rotating the second gear, the first gear and the first rotating shaft 112 can be driven to rotate, thereby driving the connecting plate 6 to rotate.

[0085] For example, in another embodiment, the angle adjustment structure includes a driving wheel, a driven wheel, a synchronous belt, and a servo motor. A driven wheel is provided on the first rotating shaft 112 at one end of the connecting plate 6, and a driving wheel is provided on the drive end of the servo motor. A synchronous belt is fitted on the driving wheel and the driven wheel. The servo motor drives the first rotating shaft 112 to rotate via the driving wheel, the synchronous belt, and the driven wheel, thereby driving the connecting plate 6 to rotate.

[0086] Optionally, the film strip slitting mechanism 10 in this embodiment further includes a vibration mechanism 12. The vibration mechanism 12 is mounted on the connecting plate 6 and is connected to the blade holder 7 via a transmission connection. The vibration mechanism 12 is configured to drive each cutter 8 on the blade holder 7 to reciprocate along the length direction of the blade edge 81. The reciprocating vibration direction of the cutter 8 is as follows: Figure 2 , Figure 4 and Figure 5 As shown by the dashed double arrow.

[0087] When the membrane is being cut, the vibration mechanism 12 drives each cutter 8 on the cutter holder 7 to vibrate back and forth along the length of the blade 81, which can effectively reduce the continuous friction force on the cutter 8 during cutting, thereby further improving the cutting effect of the membrane and obtaining membrane strips with straighter edges.

[0088] like Figures 2 to 5 As shown, optionally, the vibration mechanism 12 includes a driver 121, a second rotating shaft 122, two eccentric wheels 123 and two lifting blocks 124. The driver 121 is mounted on the connecting plate 6, the second rotating shaft 122 is horizontally arranged and connected to the driver 121 for transmission, and an eccentric wheel 123 is connected to each end of the second rotating shaft 122.

[0089] Two lifting blocks 124 are respectively disposed on both sides of the second rotating shaft 122 and are slidably connected to the connecting plate 6 in a direction perpendicular to the connecting plate 6. The tool holder 7 is fixedly connected to the two lifting blocks 124. The lifting blocks 124 are provided with waist holes 125, and two eccentric wheels 123 are respectively located in the waist holes 125 of the lifting blocks 124 on the same side. The driver 121 is used to drive the second rotating shaft 122 to rotate around the axial direction, so as to drive the lifting blocks 124 to slide back and forth via the eccentric wheels 123. The length direction of the cutting edge 81 of the blade 8 is the same as the sliding direction of the lifting block 124.

[0090] With this configuration, during the slitting process of the membrane, the driver 121 drives the second rotating shaft 122 to rotate, which in turn drives the lifting block 124 to slide back and forth, ultimately causing the cutter 8 to vibrate back and forth along the length of its blade 81. The driver 121 can be, for example, a servo motor.

[0091] like Figure 4 As shown, optionally, the two lifting blocks 124 are also buoyantly connected to the connecting plate 6 via springs 126. This arrangement allows the two lifting blocks 124 to slide back and forth under the drive of the eccentric wheel 123. Furthermore, it reduces structural resonance, ensuring that the tangential surfaces of the eccentric wheel 123 and the oblique holes within the lifting blocks 124 are in close contact, preventing frequency mismatch during vibration and thus preventing the eccentric wheel 123 from shifting.

[0092] In other embodiments, the cutter 8 can also be driven to reciprocate along the length of its blade 81 by other forms of vibration mechanisms. For example, such as... Figure 7 As shown, in another embodiment, the vibration mechanism 12 includes a motor 127, a first connecting rod 128, and a second connecting rod 129. The first connecting rod 128 is connected to the drive end of the motor 127, the first end of the second connecting rod 129 is hinged to the end of the first connecting rod 128, and the second end of the second connecting rod 129 is hinged to the tool holder 7. The tool holder 7 is slidably connected to the connecting plate 6 via a slider rail pair perpendicular to the connecting plate 17. The motor 127 drives the first connecting rod 128 to rotate, thereby driving the second connecting rod 129 to reciprocate. When the second connecting rod 129 reciprocates, it drives the tool holder 7 and its cutting blade 8 along a path perpendicular to the connecting plate 6 (e.g., ...). Figure 7 The double arrows (indicated by the dashed lines in the image) indicate the direction of the reciprocating vibration.

[0093] In other embodiments, the vibration mechanism may also use a linear drive such as a cylinder to directly drive the blade holder 7 to slide back and forth in a direction perpendicular to the connecting plate 6, so as to realize the reciprocating vibration of the cutter 8 along the length direction of its blade 81.

[0094] Based on the same inventive concept, this application also provides a membrane strip preparation apparatus. For example... Figures 8 to 11 As shown, the film strip preparation apparatus includes a support platform 20, a pressing plate 30, and a film strip cutting mechanism 10 as described in any of the above embodiments, wherein:

[0095] The support platform 20 is used to support the film to be cut. The support surface of the support platform 20 is set horizontally, and several long strip-shaped knife grooves 201 are arranged side by side at intervals on the support surface of the support platform 20.

[0096] The film strip slitting mechanism 10 is located above the support platform 20. The pressure plate 30 is horizontally arranged between the film strip slitting mechanism 10 and the support platform 20. The pressure plate 30 is provided with a number of slitting slits 301 that run from top to bottom through the pressure plate 30. The slitting slits 301, the knife groove 201 and the cutter 8 are respectively arranged one-to-one.

[0097] The pressure plate 30 is configured to press the film to be cut onto the support table 20.

[0098] The cutter 8 is used to pass downward through the slitting slit 301 and extend into the knife groove 201, and move along the length of the knife groove 201 to cut the membrane into several membrane strips.

[0099] The optional operating process of the membrane strip preparation device in this embodiment is as follows:

[0100] First, adjust the angle of the cutter 8 of the film strip slitting mechanism 10 according to the material of the film to be slitted.

[0101] After the film to be cut is fed onto the carrier table 20, the pressure plate 30 presses the film onto the carrier table 20.

[0102] Subsequently, the first lifting drive unit 2 drives the support frame 3 to descend, so that each cutter 8 passes downward through the slitting slit 301 and extends into the cutter groove 201. At this time, each cutter 8 is located on one side of the film to be cut and close to the film to be cut.

[0103] Next, the translation drive unit 4 drives the connecting bracket 5 to translate, so that each cutter 8 moves along the length direction of the cutting groove 201 to cut the membrane into several membrane strips.

[0104] As can be seen, through the cooperation of the support platform 20, the pressure plate 30, and the film strip cutting mechanism 10, the film strip preparation device in this embodiment of the application realizes automatic cutting of the film. In particular, by adjusting the installation angle of the cutter 8, the blade of the cutter 8 can be inclined to cut the film on the support platform 20, thereby reducing resistance, reducing the generation of debris, and achieving control over the cutting quality of the film.

[0105] like Figure 9 As shown, the film strip preparation device in this embodiment of the application further includes a second lifting drive unit 40, and the film pressing plate 30 is connected to the movable part of the second lifting drive unit 40. The second lifting drive unit 40 is configured to drive the film pressing plate 30 to lift and lower, and a flexible pad is also covered on the bottom surface of the film pressing plate 30.

[0106] The second lifting drive unit 40 can be installed on the mounting frame 1 of the film strip cutting mechanism 10, or it can be set separately from the film strip cutting mechanism 10.

[0107] Since the cutting blade 8 of the film strip slitting mechanism 10 is raised and lowered by the first lifting drive unit 2, and the pressure plate 30 is raised and lowered by the second lifting drive unit 40, the cutting blade 8 and the pressure plate 30 can be raised and lowered independently without interfering with each other. This configuration achieves the following technical effects:

[0108] Firstly, the clamping force of the pressure plate 30 on the diaphragm can be independently and flexibly controlled, without being limited by the current position of the cutter 8. The installation angle of the cutter 8 can also be independently and flexibly adjusted, without being limited by the current position of the pressure plate 30.

[0109] Secondly, the relative position of the cutter 8 and the pressure plate 30 can be adjusted, thereby flexibly adjusting the length of the cutter 8 extending downward from the pressure plate 30. In this way, when the blade section of the cutter 8 currently used to cut the film becomes dull, the relative position of the cutter 8 and the pressure plate 30 can be adjusted so that the other undulled blade section of the cutter 8 can cut the film, thereby extending the service life of the cutter 8.

[0110] Because the bottom surface of the pressure plate 30 is covered with a flexible pad, the pressure plate 30 can flexibly press the diaphragm onto the support platform, ensuring that the diaphragm can be pressed onto the support platform from all directions, ultimately improving the slitting effect of the diaphragm.

[0111] like Figure 9 As shown, optionally, the second lifting drive unit 40 includes two lifting drive assemblies arranged opposite each other. The two lifting drive assemblies each include a fixed frame 401, a movable frame 402, and a lifting drive component 403. The fixed frame 401 is fixedly arranged, and the movable frame 402 is longitudinally movably connected to the fixed frame 401 and connected to the drive end of the lifting drive component 403 arranged on the fixed frame 401. The two ends of the pressure plate 30 are respectively connected to the two movable frames 402.

[0112] With this configuration, the two opposing lifting drive components synchronously drive the pressure plate 30 to rise and fall from both ends, ensuring that the pressure plate 30 rises and falls stably in a horizontal state, thereby further improving the pressing effect of the pressure plate 30 on the diaphragm.

[0113] The lifting drive component 403 can be a linear drive component such as a cylinder or an electric cylinder.

[0114] like Figure 8 and Figure 10 As shown, optionally, the film strip preparation apparatus in this embodiment further includes a first moving part (not shown) and a conveying mechanism 50. A support platform 20 is connected to a movable component of the first moving part, and the support platform 20 is provided with adsorption holes 202 for adsorbing the film. The first moving part drives the support platform 20 to reciprocate between the film-attaching station and the slitting station. The conveying mechanism 50 is movable to the film-attaching station, where the pressure plate 30 and the film strip slitting mechanism 10 are located. The conveying mechanism 50 is configured to lay the film strip 100 to be slit onto the support platform 20 located at the film-attaching station. The pressure plate 30 and the film strip slitting mechanism 10 are configured to press and slit the film strip 100 on the support platform 20 moved to the slitting station.

[0115] Driven by the first moving part, the carrier platform 20 can reciprocate between the film splicing station and the slitting station. Thus, when the carrier platform 20 switches to the film splicing station, the transport mechanism 50 can lay the film to be slitted onto the carrier platform 20 located at the film splicing station, avoiding interference with the pressure plate 30 and the film strip slitting mechanism 10. When the carrier platform 20 switches to the slitting station, it can cooperate with the pressure plate 30 and the film strip slitting mechanism 10 to perform normal slitting of the film.

[0116] The support platform 20 can adsorb the membrane sheet and the membrane strip obtained after slitting through the adsorption holes 202 on it, so as to prevent the membrane sheet and membrane strip from shifting during the movement.

[0117] like Figure 11 As shown, optionally, the conveying mechanism 50 includes a second moving part 501 and an adsorption plate 502, wherein the adsorption plate 502 is connected to a movable part of the second moving part 501. The second moving part 501 is used to drive the adsorption plate 502 to move, so as to drive the adsorption plate 502 to adsorb the film 100 to be cut, and release the film 100 onto the support stage 20.

[0118] Both the first moving part and the second moving part 501 can be robotic arms, robotic hands, or drive devices with translation and lifting functions, which are composed of 2-3 linear modules.

[0119] It should be noted here that the film strip slitting mechanism 10 in this application is used in... Figures 8 to 11 In the membrane strip preparation apparatus shown in the embodiment, both the membrane strip and the pressure plate 30 are located on the upper side of the support platform 20.

[0120] In other application scenarios, the film strip slitting mechanism 10 can also be located on the lower side of the support platform 20, with the pressure plate located on the upper side of the support platform. In this case, the support platform 20 needs to be provided with several slitting slits corresponding one-to-one with the cutters 8 of the film strip slitting mechanism 10, and the bottom of the pressure plate 30 needs to be provided with several knife-relief grooves corresponding one-to-one with the cutters 8 of the film strip slitting mechanism 10. Each cutter 8 of the film strip slitting mechanism 10 passes upward through the corresponding slitting slit and then into the corresponding knife-relief groove, and moves along the knife-relief groove to slitting the film sheet pressed by the pressure plate 30.

[0121] This application provides a sufficiently detailed and specific description. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within its protection scope. The scope of protection claimed in this application is defined by the claims, not by the above descriptions in the embodiments. Without contradiction, some optional components in one embodiment can also be used in another embodiment, and some preferred structures of the same component in one embodiment are also applicable to another embodiment. Furthermore, there may be slight differences in the wording of the names of certain components in different embodiments; these slight differences will not affect the understanding of the technical solution of the present invention by those skilled in the art.
