Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment, specifically a film tape pressing and cutting mechanism and a film tape cutting device. Background Technology

[0002] In the production process of photovoltaic modules, it is often necessary to use a film cutting device to cut film sheets of a predetermined length from the film tape roll.

[0003] Existing film tape cutting devices generally include components such as a feeding mechanism, a film tape pressing and cutting mechanism, a cutting platform, and a traction mechanism. The free end of the film tape released by the feeding mechanism passes through the film tape pressing and cutting mechanism. The traction mechanism clamps the free end of the film tape from the film tape pressing and cutting mechanism and pulls the film tape of a predetermined length onto the cutting platform.

[0004] The film tape clamping and cutting mechanism includes a first clamping assembly, a second clamping assembly, and a cutting assembly. After the traction mechanism pulls a film tape of a predetermined length onto the cutting platform, the first clamping assembly clamps the film tape, and the second clamping assembly clamps the film tape to the end of the cutting platform. The cutting assembly then cuts the film tape between the first and second clamping assemblies, thereby obtaining a film sheet on the cutting platform. The new free end of the film tape after cutting is clamped and held within the first clamping assembly.

[0005] In order for the traction mechanism's clamp to grip the free end of the membrane strip that is clamped by the first clamping assembly, the first clamping assembly typically includes an upper toothed pressure plate and a lower toothed carrier plate. The teeth on the upper toothed pressure plate and the lower toothed carrier plate are aligned one to one. When they are close together, the membrane strip is clamped by the teeth. A space is formed between two adjacent teeth for the traction mechanism's clamp to extend into, so that the clamp can grip the end of the membrane strip.

[0006] However, when the membrane tape is pressed together using an upper toothed pressure plate and a lower toothed carrier plate, wrinkles easily form on the tape, resulting in wavy edges on the cut edges after cutting, ultimately leading to wavy edges on the obtained membrane sheet. Utility Model Content

[0007] To address the aforementioned technical problems, this application provides a membrane tape pressing and cutting mechanism, the detailed technical solution of which is as follows:

[0008] A membrane tape pressing and cutting mechanism is used to press a membrane tape and cut a membrane sheet off the membrane tape. The membrane tape pressing and cutting mechanism includes a first pressing component, a second pressing component, a third pressing component, and a cutting component, wherein the first pressing component, the third pressing component, and the second pressing component are arranged sequentially along a first direction.

[0009] The membrane belt passes sequentially through the first pressing assembly, the third pressing assembly, and the second pressing assembly along the first direction;

[0010] The first clamping assembly includes a first bearing plate and a first pressing plate, the third clamping assembly includes a second bearing plate and a second pressing plate, and the second clamping assembly includes a third pressing plate, wherein at least the bearing surface of the second bearing plate and the pressing surface of the second pressing plate are planar.

[0011] The first pressure plate is configured to press the film strip onto the first pressure plate, the second pressure plate is configured to press the film strip onto the second pressure plate at least, and the third pressure plate is configured to press the film strip.

[0012] The cutting assembly is configured to cut the compressed membrane strip from the gap between the second and third pressure plates to obtain a membrane sheet;

[0013] After the membrane tape is cut, the second pressure plate is configured to rise to release the membrane tape; the second pressure plate is configured to fall, or the first pressure plate and the first pressure plate are configured to drive the pressed membrane tape to rise, such that the cut end of the membrane tape is suspended between the second pressure plate and the second pressure plate.

[0014] The film tape pressing and cutting mechanism provided in this application, when in use, after the external film tape traction mechanism pulls the film tape of a predetermined length to the external cutting platform, the first pressure plate can press the film tape onto the first pressure plate, the second pressure plate can press the film tape onto the second pressure plate, and the third pressure plate can press the film tape onto the cutting platform. Then, the cutting component cuts the pressed film tape between the second and third pressure plates to obtain a film sheet. Since the pressing surfaces of the second pressure plate and the second pressure plate are both flat, the horizontality of the pressed film tape can be ensured, thereby ensuring that the cutting component obtains a straight cutting edge after cutting the film tape, and ultimately avoiding the appearance of wavy edges on the obtained film sheet.

[0015] After the diaphragm is obtained, the third pressure plate rises to release the film strip from the cutting platform. Simultaneously, the second pressure plate and the second bearing plate rise and fall in opposite directions, moving away from the film strip; alternatively, the second pressure plate rises to release the film strip, while the first clamping assembly holds the film strip in place and pulls it upwards. In both methods, the newly free end of the cut film strip is suspended between the second bearing plate and the second pressure plate. This allows the traction mechanism to smoothly clamp the free end of the film strip during the next traction operation.

[0016] As can be seen, the membrane tape pressing and cutting mechanism provided in this application not only ensures the straightness of the cut edge of the membrane tape, but also ensures that the new free end of the membrane tape after cutting can be exposed to the membrane tape pressing and cutting mechanism, so as to facilitate the membrane tape traction mechanism to clamp it again.

[0017] In some embodiments, both the bearing surface of the first bearing plate and the pressing surface of the first pressure plate are planar.

[0018] Since the bearing surface of the first pressure plate and the pressing surface of the first pressure plate are also set as planes, wrinkles are avoided in the membrane strip area pressed by the first pressing component, thus further ensuring the overall straightness of the cut membrane sheet.

[0019] In some embodiments, the film tape pressing and cutting mechanism further includes a first mounting frame, a first pressure plate fixedly mounted on the first mounting frame or movably mounted on the first mounting frame, and a support plate provided on the first pressure plate; the first pressing assembly further includes a second lifting drive member, the second lifting drive member is mounted on the support plate, the first pressure plate is connected to the movable part of the second lifting drive member, and the second lifting drive member is used to drive the first pressure plate to rise and fall, so that the first pressure plate presses the film tape onto the first pressure plate or releases the film tape; the third pressing assembly further includes a third lifting drive member and a fourth lifting drive member, the third lifting drive member... The second pressure plate is mounted on the first mounting bracket and on the movable part of the third lifting drive; the fourth lifting drive is mounted on the support plate and the second pressure plate is mounted on the movable part of the fourth lifting drive; the third and fourth lifting drives are configured to drive the second pressure plate and the second pressure plate to move in opposite directions, so that the second pressure plate and the second pressure plate approach or separate; when the second pressure plate and the second pressure plate approach, the second pressure plate presses the membrane tape onto the second pressure plate and the first pressure plate; when the second pressure plate and the second pressure plate separate, the cut end of the membrane tape is suspended between the second pressure plate and the second pressure plate.

[0020] By setting up a first mounting bracket and a support plate on the first mounting bracket, installation space is provided for the first clamping assembly and the third clamping assembly, ensuring that the first clamping assembly and the third clamping assembly can smoothly carry out the corresponding operations.

[0021] Before cutting the membrane strip, the second lifting drive unit drives the first pressure plate to descend, causing the first pressure plate to press the membrane strip tightly against the first pressure plate. The fourth and third lifting drive units drive the second pressure plate and the second pressure plate to move in the opposite direction to the membrane strip, causing the second pressure plate to simultaneously press the membrane strip against both the first and second pressure plates. Because the second pressure plate presses the membrane strip simultaneously against both the second and first pressure plates, the first pressure plate supports the second pressure plate, thus preventing the fourth and third lifting drive units from colliding and causing damage to them.

[0022] After the cutting assembly cuts the compressed membrane strip to obtain the membrane sheet, the fourth and third lifting drive components drive the second pressure plate and the second bearing plate to move away from the membrane strip and rise and fall in the opposite direction, so that the new free end of the membrane strip after cutting is suspended between the second bearing plate and the second pressure plate.

[0023] Furthermore, since the second lifting drive is mounted on the support plate, and the support plate is mounted on the first bearing plate, when the first pressure plate is movably mounted on the first mounting frame, after the cutting component cuts the film strip, the first pressure plate can be controlled to rise, thereby creating a height difference between the new free end of the film strip after cutting and the external cutting platform, thus avoiding the traction mechanism from contacting and interfering with the cutting platform when performing the next traction.

[0024] In some embodiments, the film tape pressing and cutting mechanism further includes a first lifting drive member, which is connected to the first pressure plate and is used to drive the first pressure plate to lift.

[0025] When the first pressure plate is movably mounted on the first mounting frame, the lifting and lowering adjustment of the first pressure plate is achieved by setting the first lifting drive component.

[0026] In some embodiments, the film tape pressing and cutting mechanism further includes a first mounting frame, on which a first lifting drive is disposed, a first pressure plate is pulsatorically connected to the first lifting drive, and a support plate is disposed on the first pressure plate; the first pressing assembly further includes a second lifting drive, which is mounted on the support plate, and the first pressure plate is connected to a movable part of the second lifting drive, the second lifting drive being used to drive the first pressure plate to rise and fall, so that the first pressure plate presses the film tape onto the first pressure plate or releases the film tape; the third pressing assembly further includes a fourth lifting drive, the second... The pressure plate is fixed on the first mounting bracket; the fourth lifting drive is mounted on the support plate or the first mounting bracket, and the second pressure plate is mounted on the movable part of the fourth lifting drive; the fourth lifting drive is configured to drive the second pressure plate to rise and fall, so that the second pressure plate presses the film strip onto the second pressure plate or releases the film strip; after the film strip is cut and the second pressure plate releases the film strip, the first lifting drive and the second lifting drive are configured to synchronously drive the first pressure plate and the first pressure plate to rise, so that the clamped film strip rises, and the cut end of the film strip is suspended between the second pressure plate and the second pressure plate.

[0027] By setting up a first mounting bracket and a support plate on the first mounting bracket, installation space is provided for the first clamping component and the third clamping component, and it is ensured that the first clamping component and the third clamping component can smoothly carry out the corresponding operation.

[0028] Before cutting the membrane strip, the fourth lifting drive unit drives the second pressure plate to descend, causing the second pressure plate to press the membrane strip against the second pressure plate. Simultaneously, the second lifting drive unit drives the first pressure plate to move towards the membrane strip, causing the first pressure plate to press the membrane strip against the first pressure plate. Specifically, since the second pressure plate is fixed to the first mounting bracket, the second pressure plate only needs to press the membrane strip against the second pressure plate; the fourth lifting drive unit is not at risk of being damaged by impact.

[0029] After the cutting assembly cuts the compressed membrane strip to obtain the membrane sheet, the first and second lifting drive components synchronously drive the first pressure plate and the first pressure plate to rise, thereby causing the membrane strip to automatically detach from the second pressure plate. This results in the newly free end of the membrane strip, created by the cutting, being suspended between the second pressure plate and the second pressure plate. Furthermore, this process increases the height difference between the newly free end of the membrane strip and the external cutting platform, preventing the traction mechanism from interfering with the cutting platform during the next traction operation.

[0030] In some embodiments, the cutting assembly includes a first translational drive and a cutter, wherein: the first translational drive is mounted on a first mounting bracket, and the cutter is connected to a movable part of the first translational drive; the first translational drive is configured to drive the cutter to translate along a second direction such that the cutter passes through the gap between the second pressure plate and the third pressure plate to cut the compressed film strip, wherein the second direction is perpendicular to the first direction.

[0031] The first translational drive unit drives the cutter to move through the gap between the second and third pressure plates to cut the compressed film strip, ensuring the flatness of the film strip cutting edge.

[0032] In some embodiments, the second clamping assembly further includes a fifth lifting drive member, which is mounted on the first mounting bracket. The third pressure plate is connected to a movable part of the fifth lifting drive member. The fifth lifting drive member is used to drive the third pressure plate to rise or fall, causing the third pressure plate to clamp or release the membrane strip; or...

[0033] The film belt pressing and cutting mechanism also includes a second mounting frame, and the second pressing assembly also includes a fifth lifting drive component. The fifth lifting drive component is mounted on the second mounting frame, and the third pressure plate is connected to the movable part of the fifth lifting drive component. The fifth lifting drive component is used to drive the third pressure plate to lift and lower, so that the third pressure plate presses or releases the film belt. The first mounting frame and the second mounting frame are configured to be close to or far from each other, so that the second pressure plate and the third pressure plate are close to or far from each other.

[0034] By setting a fifth lifting drive component, the lifting drive of the third pressure plate is realized, so that the third pressure plate can press the film strip to the external cutting platform before the cutting component cuts the film strip, and release the film after the cutting component cuts the film strip to obtain the film sheet.

[0035] Integrating the fifth lifting drive component onto the first mounting bracket makes the structure of this application more concise and compact. Mounting the fifth lifting drive component onto a separate second mounting bracket, and configuring the first and second mounting brackets to be close to or far from each other, allows for flexible adjustment of the distance between the second and third pressure plates. This ensures that both the second and third pressure plates can smoothly perform their respective pressing operations, and facilitates control over the gap between them, guaranteeing the cutting quality of the film strip by the cutter.

[0036] In some embodiments, the film tape pressing and cutting mechanism further includes a second translation drive and a base, wherein: the first mounting bracket is slidably mounted on the base along a first direction, the first mounting bracket is drively connected to the second translation drive mounted on the base, and the second translation drive is configured to drive the first mounting bracket to translate along the first direction.

[0037] By setting up a second translation drive and a base, the distance between the components on the first mounting frame and the external cutting platform can be adjusted. When the components on the first mounting frame move to a clearance position away from the cutting platform, they serve to clear the way, allowing the subsequent handling mechanism (e.g., a moving suction cup) to remove the film from the cutting platform. When the components on the first mounting frame move to a working position close to the cutting platform, they can cooperate to perform the pressing and cutting operations on the film strip.

[0038] This application also provides a film tape cutting device, which includes a film tape traction mechanism and a film tape feeding mechanism, a film tape pressing and cutting mechanism, and a cutting platform arranged sequentially along a first direction. The film tape pressing and cutting mechanism is any one of the film tape pressing and cutting mechanisms described above, wherein:

[0039] The film tape feeding mechanism is configured to carry the film tape roll and drive the film tape roll to rotate to feed the film tape.

[0040] The film strip released from the film roll passes sequentially through the first clamping assembly, the third clamping assembly, and the second clamping assembly along the first direction and is clamped by the film strip traction mechanism, which is configured to pull the clamped film strip to the cutting platform.

[0041] When the film belt is pulled onto the cutting platform, the first pressure plate is configured to press the film belt onto the first pressure plate, the second pressure plate is configured to press the film belt onto the second pressure plate at least, and the third pressure plate is configured to press the film belt onto the first end of the cutting platform;

[0042] The cutting assembly is configured to cut the compressed film strip from the gap between the second and third pressure plates to obtain a film sheet on the cutting platform;

[0043] After the membrane tape is cut, the second pressure plate is configured to rise to release the membrane tape; the second pressure plate is configured to descend away from the membrane tape, or the second pressure plate and the second pressure plate are configured to drive the pressed membrane tape to rise, such that the cut end of the membrane tape is suspended between the second pressure plate and the second pressure plate.

[0044] By coordinating the film tape feeding mechanism, the film tape pressing and cutting mechanism, and the cutting platform, the film tape cutting device of this application realizes the automatic cutting of the film tape released from the film tape roll, thereby achieving the automatic preparation of the film sheet. In particular, since the pressing surfaces of the second pressure plate and the second pressure plate of the film tape pressing and cutting mechanism are both flat, the horizontality of the pressed film tape can be guaranteed, thereby ensuring that the cutting assembly obtains a straight cutting edge after cutting the film tape, and ultimately avoiding the appearance of wavy lines on both sides of the obtained film sheet.

[0045] In addition, after obtaining the diaphragm, by controlling the second pressure plate and the second bearing plate to rise and fall in opposite directions, or by first controlling the second pressure plate to rise and release the diaphragm belt, and then controlling the first pressing component to drive the pressed diaphragm belt to rise, the new free end of the diaphragm belt produced by the cutting can be exposed to the diaphragm belt pressing and cutting mechanism, so that the traction mechanism can smoothly clamp the free end of the diaphragm belt when performing the next traction.

[0046] In some embodiments, the distance between the cutting platform and the second pressure plate in the film belt pressing and cutting mechanism in the first direction can be adjusted; the cutting platform and the second pressure plate in the film belt pressing and cutting mechanism can be staggered or aligned with each other in the height direction.

[0047] Because the distance between the cutting platform and the second pressure plate in the film belt pressing and cutting mechanism is adjustable in the first direction, the distance between the cutting platform and the second pressure plate can be adjusted to a smaller first distance before the film belt traction mechanism pulls the film belt to the cutting platform. This ensures that the traction mechanism can smoothly clamp the free end of the film belt from the film belt pressing and cutting mechanism and pull the film belt of a predetermined length to the cutting platform. It also ensures that the first pressing assembly, the third pressing assembly, and the cutting assembly can cooperate with the second pressing assembly to complete the pressing and cutting of the film belt. After the cutting assembly completes the cutting of the film belt, the distance between the cutting platform and the second pressure plate is adjusted to a larger second distance to facilitate the subsequent handling mechanism (e.g., a moving suction cup) to remove the film belt from the cutting platform.

[0048] Since the cutting platform and the second pressure plate in the film belt pressing and cutting mechanism can be staggered or aligned with each other in the height direction, after the traction mechanism pulls the film belt onto the cutting platform, it can adjust the cutting platform and the second pressure plate to be aligned with each other in the height direction. This ensures that the first pressing assembly, the third pressing assembly, and the cutting assembly can cooperate with the second pressing assembly to complete the pressing and cutting of the film belt. After the cutting assembly completes the cutting of the film belt, it can adjust the cutting platform and the second pressure plate to be staggered in the height direction. This ensures that when the traction mechanism performs the next traction, a height difference is formed between the cut end of the film belt (i.e., the new free end produced by cutting) and the cutting platform, avoiding contact and interference between the traction mechanism and the cutting platform.

[0049] In some embodiments, the film belt traction mechanism includes a drive unit and a clamping assembly, wherein the clamping assembly is connected to a movable part of the drive unit and is used to clamp the film belt, and the drive unit is at least used to drive the clamping assembly to translate in a first direction; the clamping assembly includes a lower clamping plate and an upper clamping plate that can be clamped together, wherein: the clamping surface of the lower clamping plate is a plane; the clamping surface of the upper clamping plate is a plane, or, the upper clamping plate is provided with a plurality of pressure teeth.

[0050] A simple and stable film strip traction mechanism is provided, which ensures that the free end of the film strip is clamped from the film strip pressing and cutting mechanism and pulled onto the cutting platform. Setting the clamping surface of the lower clamping plate as a plane can improve the straightness of the free end and avoid wrinkles. Attached Figure Description

[0071] 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.

[0072] As described in the background section, existing film tape clamping and cutting mechanisms include a first clamping assembly, a second clamping assembly, and a cutting assembly. After a traction mechanism pulls a film tape of a predetermined length onto a cutting platform, the first clamping assembly clamps the film tape, and the second clamping assembly clamps the film tape to the end of the cutting platform. The cutting assembly then cuts the film tape between the first and second clamping assemblies, thereby obtaining a film sheet on the cutting platform. The new free end of the film tape after cutting is clamped and held within the first clamping assembly.

[0073] In order for the traction mechanism's clamp to grip the free end of the membrane strip that is clamped by the first clamping assembly, the first clamping assembly typically includes an upper toothed pressure plate and a lower toothed carrier plate. The teeth on the upper toothed pressure plate and the lower toothed carrier plate are aligned one to one. When they are close together, the membrane strip is clamped by the teeth. A space is formed between two adjacent teeth for the traction mechanism's clamp to extend into, so that the clamp can grip the end of the membrane strip.

[0074] However, when the membrane tape is pressed with an upper toothed pressure plate and a lower toothed carrier plate, wrinkles are likely to appear on the membrane tape, resulting in wavy lines on the cut edges of the membrane tape after cutting, which ultimately leads to wavy lines on the edges of the obtained membrane sheet.

[0075] Therefore, this application provides a membrane tape pressing and cutting mechanism, which is used to press the membrane tape and cut the membrane sheet off the membrane tape, and can avoid the appearance of wavy lines on the cut edge of the membrane tape after cutting.

[0076] like Figures 1 to 3 As shown, the film tape pressing and cutting mechanism 10 in this embodiment includes a first pressing component 1, a second pressing component 3, a third pressing component 2 and a cutting component 4, wherein the first pressing component 1, the third pressing component 2 and the second pressing component 3 are arranged sequentially along a first direction (such as the X direction).

[0077] The membrane belt 100 passes sequentially through the first pressing assembly 1, the third pressing assembly 2, and the second pressing assembly 3 along the first direction.

[0078] The first pressing assembly 1 includes a first pressure plate 11 and a first pressure plate 12, the third pressing assembly 2 includes a second pressure plate 21 and a second pressure plate 22, and the second pressing assembly 3 includes a third pressure plate 31, wherein at least the pressure-bearing surface of the second pressure plate 21 and the pressing surface of the second pressure plate 22 are planar.

[0079] The first pressure plate 12 is configured to press the membrane belt 100 onto the first pressure plate 11, the second pressure plate 22 is configured to press the membrane belt 100 onto the second pressure plate 21 at least, and the third pressure plate 31 is configured to press the membrane belt 100.

[0080] The cutting assembly 4 is configured to cut the compressed membrane strip 100 from the gap between the second pressure plate 22 and the third pressure plate 31 to obtain a membrane sheet.

[0081] After the membrane belt 100 is cut, the second pressure plate 22 is configured to rise to release the membrane belt 100. The second pressure plate 21 is configured to fall, or the first pressure plate 12 and the first pressure plate 11 are configured to drive the pressed membrane belt 100 to rise, such that the cut end of the membrane belt 100 is suspended between the second pressure plate 21 and the second pressure plate 22.

[0082] The optional working process of the membrane tape pressing and cutting mechanism 10 provided in this application is as follows:

[0083] In the initial state, the first pressure plate 12 presses the membrane belt 100 tightly onto the first pressure plate 11. The free end of the membrane belt 100 is suspended between the second pressure plate 21 and the second pressure plate 22. The third pressure plate 31 is located above the end of the external cutting platform.

[0084] When the external membrane belt traction mechanism clamps the free end of the membrane belt 100, the first pressure plate 12 rises to release the membrane belt 100.

[0085] After the film belt traction mechanism pulls the film belt 100 of a predetermined length onto the cutting platform, the third pressure plate 31 descends to press the film belt 100 against the end of the cutting platform, and the first pressure plate 12 and the second pressure plate 22 descend to press the film belt 100 against the platform. The bearing surfaces of the first pressure plate 11, the second pressure plate 21, and the cutting platform are adjusted to be flush with each other in the height direction.

[0086] Subsequently, the cutting assembly 4 cuts the compressed film strip 100 between the second pressure plate 22 and the third pressure plate 31, thereby obtaining a film sheet located on the cutting platform.

[0087] The third pressure plate 31 rises to release the diaphragm, and the second pressure plate 22 rises to release the membrane belt 100. In addition, the second pressure plate 21 is controlled to descend, or the first pressure plate 12 and the first pressure plate 11 are controlled to drive the pressed membrane belt 100 to rise, so that the new free end (i.e. the cut end) of the membrane belt 100, which is generated by cutting, is suspended between the second pressure plate 21 and the second pressure plate 22.

[0088] At this point, the membrane tape pressing and cutting mechanism 10 returns to its initial state, ready for the next membrane tape cutting.

[0089] Since the cutting assembly 4 cuts the membrane strip 100 pressed by the second pressing assembly 3 and the third pressing assembly 2 between the second pressing assembly 3 and the third pressing assembly 2, and the pressing surfaces of the second pressure plate 22 and the second pressure plate 21 of the third pressing assembly 2 are both flat, the horizontality of the pressed membrane strip 100 can be guaranteed, thereby ensuring that the cutting assembly 4 obtains a straight cut edge after cutting the membrane strip 100, and ultimately avoiding the appearance of wavy lines at the edge of the obtained membrane.

[0090] Furthermore, after the cutting assembly 4 cuts the membrane belt 100, by controlling the second pressure plate 22 and the second bearing plate 21 to move away from the membrane belt 100 and rise in the opposite direction, or by controlling the first pressing assembly 1 to drive the pressed membrane belt 100 to rise, the newly free end of the membrane belt 100, which has been cut, can be suspended between the second bearing plate 21 and the second pressure plate 22, or in other words, the newly free end of the membrane belt 100, which has been cut, can be exposed to the membrane belt pressing and cutting mechanism 10. In this way, the membrane belt traction mechanism can smoothly clamp the free end of the membrane belt 100 when performing the next traction.

[0091] As can be seen, the membrane tape pressing and cutting mechanism 10 provided in this application not only ensures the straightness of the cut edge of the membrane tape 100, thereby avoiding wavy lines at the edge of the obtained membrane sheet, but also ensures that the new free end of the membrane tape 100 after cutting is exposed to the membrane tape pressing and cutting mechanism 10, so as to facilitate the membrane tape traction mechanism to clamp it again.

[0092] In some embodiments, the bearing surface of the first pressure plate 11 and the pressing surface of the first pressure plate 12 are both planar. By setting the bearing surface of the first pressure plate 11 and the pressing surface of the first pressure plate 12 to be planar, wrinkles can be avoided at the part of the membrane strip 100 pressed by the first pressing assembly 1, thereby further improving the overall flatness of the obtained membrane.

[0093] As mentioned above, in order to suspend the new free end of the membrane strip 100, which is produced by cutting, between the second bearing plate 21 and the second pressure plate 22, this application provides two optional implementation methods:

[0094] The first implementation method is as follows: the cutting component 4 cuts the compressed membrane strip 100, and after the second pressure plate 22 rises to release the membrane strip 100, the second pressure plate 21 is controlled to descend, so that the second pressure plate 21 also detaches from the membrane strip 100, and the new free end of the membrane strip 100 is suspended between the second pressure plate 21 and the second pressure plate 22.

[0095] The second implementation method is as follows: the cutting component 4 cuts the compressed membrane strip 100, and after the second pressure plate 22 rises to release the membrane strip 100, the first pressure plate 12 and the first bearing plate 11 are controlled to drive the compressed membrane strip 100 to rise, so that the membrane strip 100 actively detaches from the second bearing plate 21, and finally the new free end of the membrane strip 100 is suspended between the second bearing plate 21 and the second pressure plate 22.

[0096] The following will provide an exemplary description of the two implementation methods described above through two specific embodiments.

[0097] like Figures 1 to 3 As shown, corresponding to the first implementation described above, the film tape pressing and cutting mechanism 10 in this embodiment further includes a first mounting frame 7. A first pressure plate 11 is fixedly mounted on the first mounting frame 7 or can be lifted and lowered on the first mounting frame 7, and a support plate 5 is provided on the first pressure plate 11.

[0098] The first pressing assembly 1 also includes a second lifting drive 13, which is mounted on the support plate 5. The first pressure plate 12 is connected to the movable part of the second lifting drive 13. The second lifting drive 13 is used to drive the first pressure plate 12 to rise and fall, so that the first pressure plate 12 presses the film strip onto the first pressure plate 11 or releases the film strip.

[0099] The third clamping assembly 2 also includes a third lifting drive 23 and a fourth lifting drive 24. The third lifting drive 23 is mounted on the first mounting bracket 7, and the second pressure plate 21 is mounted on the movable part of the third lifting drive 23. The fourth lifting drive 24 is mounted on the support plate 5, and the second pressure plate 22 is mounted on the movable part of the fourth lifting drive 24. The third lifting drive 23 and the fourth lifting drive 24 are configured to drive the second pressure plate 21 and the second pressure plate 22 to move up and down in opposite directions, so that the second pressure plate 21 and the second pressure plate 22 move closer together or apart.

[0100] When the second pressure plate 21 and the second pressure plate 22 come together, the second pressure plate 22 presses the membrane strip tightly onto the second pressure plate 21 and the first pressure plate 11. When the second pressure plate 21 and the second pressure plate 22 separate, the cut end of the membrane strip is suspended between the second pressure plate 21 and the second pressure plate 22.

[0101] As can be seen, by setting the first mounting frame 7 and the support plate 5 on the first mounting frame 7, installation space is provided for the first pressing component 1 and the third pressing component 2, and it is ensured that the first pressing component 1 and the third pressing component 2 can smoothly press and release the membrane belt 100.

[0102] Before the cutting assembly 4 cuts the membrane belt 100, the second lifting drive 13 drives the first pressure plate 12 to descend, thereby pressing the membrane belt 100 against the first pressure plate 11. At the same time, the fourth lifting drive 24 and the third lifting drive 23 respectively drive the second pressure plate 22 and the second pressure plate 21 to move in the opposite direction toward the membrane belt 100, thereby pressing the membrane belt 100 against the second pressure plate 21 and the first pressure plate 11.

[0103] In this way, on the one hand, the third pressing component 2 can achieve pressing and fixing of the membrane belt 100. On the other hand, since the first pressure plate 11 supports the second pressure plate 22, it avoids the fourth lifting drive component 24 driving the second pressure plate 22 from colliding with the third lifting drive component 23 driving the second pressure plate 21, which would cause the fourth lifting drive component 24 and the third lifting drive component 23 to be damaged by excessive pressure.

[0104] Of course, in order for the second pressure plate 22 to press the membrane strip 100 onto the second pressure plate 21 and the first pressure plate 11 simultaneously, the width dimension of the second pressure plate 22 along the first direction needs to be adaptively set to ensure that the projection of the second pressure plate 22 on the horizontal plane covers the edge areas of the second pressure plate 21 and the first pressure plate 11.

[0105] After the cutting assembly 4 cuts the compressed membrane belt 100, the fourth lifting drive 24 and the third lifting drive 23 drive the second pressure plate 22 and the second bearing plate 21 to move away from the membrane belt 100 and move in the opposite direction, so that the new free end of the membrane belt 100 after cutting is suspended between the second bearing plate 21 and the second pressure plate 22.

[0106] Furthermore, since the second lifting drive component 13 is mounted on the support plate 5, and the support plate 5 is mounted on the first bearing plate, in the case where the first pressure plate 11 is movably mounted on the first mounting bracket 7, after the cutting assembly 4 cuts the compressed film strip 100, it can control the first pressure plate 11 to rise, thereby creating a height difference between the new free end of the film strip 100 after cutting and the external cutting platform, thus preventing the traction mechanism from contacting and interfering with the cutting platform during the next traction operation.

[0107] The second lifting drive component 13, the third lifting drive component 23, and the fourth lifting drive component 24 can all adopt existing lifting drive devices such as cylinders and electric cylinders.

[0108] In the case where the first pressure plate 11 is movably mounted on the first mounting bracket 7, such as Figures 1 to 2 As shown, the film tape pressing and cutting mechanism 10 in this embodiment of the application further includes a first lifting drive 6, which is connected to the first pressure plate 11 in a transmission manner and is used to drive the first pressure plate 11 to rise and fall.

[0109] Because the first pressure plate 11 is supported by a support plate 5, and the second lifting drive component 13 and the fourth lifting drive component 24 are both mounted on the support plate 5, the first pressure plate 11 experiences a large load. To improve the lifting stability of the first pressure plate 11, such as... Figure 2 As shown, optionally, two first lifting drive components 6 are configured, and the two first lifting drive components 6 are respectively connected to the two ends of the first pressure plate 11 along the second direction (such as the Y direction). The two first lifting drive components 6 synchronously drive the first pressure plate 11 to rise and fall. Wherein, the second direction is perpendicular to the first direction.

[0110] The first lifting drive component 6 can be an existing lifting drive device such as a cylinder or an electric cylinder.

[0111] Corresponding to the second implementation described above, another embodiment of this application provides a corresponding implementation structure for the film tape pressing and cutting mechanism 10. The film tape pressing and cutting mechanism in this embodiment is similar to... Figures 1 to 3 The membrane tape pressing and cutting mechanism 10 in the illustrated embodiment has a basically the same structure. Therefore, for ease of description, the same components will continue to be referred to as such in the following text. Figures 1 to 3 Names and reference numerals in the embodiments.

[0112] Specifically, the film tape pressing and cutting mechanism 10 in this embodiment further includes a first mounting frame 7, on which a first lifting drive member 6 is disposed, and a first pressure plate 11 is connected to the first lifting drive member 6 in a transmission manner. A support plate 5 is disposed on the first pressure plate 11. That is, in this embodiment, the first pressure plate 11 is limited to being able to move up and down relative to the first mounting frame 7 under the drive of the first lifting drive member 6.

[0113] The first pressing assembly 1 also includes a second lifting drive 13, which is mounted on the support plate 5. The first pressure plate 12 is connected to the movable part of the second lifting drive 13. The second lifting drive 13 is used to drive the first pressure plate 12 to lift and lower, so that the first pressure plate 12 presses the membrane belt 100 onto the first pressure plate 11 or releases the membrane belt 100.

[0114] The third pressing assembly 2 also includes a fourth lifting drive 24, and the second pressure plate 21 is fixed to the first mounting bracket 7. The fourth lifting drive 24 is mounted on the support plate 5 or the first mounting bracket 7, and the second pressure plate 22 is mounted on the movable part of the fourth lifting drive 24. The fourth lifting drive 24 is configured to drive the second pressure plate 22 to rise and fall, such that the second pressure plate 22 presses the membrane belt 100 against the second pressure plate 21 or releases the membrane belt 100. That is, since the second pressure plate 21 is fixed to the first mounting bracket 7, it is connected to the second pressure plate 21. Figures 1 to 3 Compared to the embodiment shown, the film tape pressing and cutting mechanism 10 in this embodiment does not require a third lifting drive component 23.

[0115] When the cutting assembly 4 cuts the compressed film strip 100, and the second pressure plate 22 rises and releases the film strip 100, the first lifting drive 6 and the second lifting drive 13 are configured to synchronously drive the first bearing plate 11 and the first pressure plate 12 to rise, thereby causing the film strip 100 clamped by the first bearing plate 11 and the first pressure plate 12 to rise, ultimately causing the cut end of the film strip 100 to be suspended between the second bearing plate 21 and the second pressure plate 22.

[0116] It can be seen that, with Figures 1 to 3 The same embodiment is shown. By setting a first mounting frame 7 and a support plate 5 on the first mounting frame 7, the installation of the first pressing component 1 and the third pressing component 2 is facilitated, and it is ensured that they can smoothly press and release the membrane belt 100.

[0117] Before the cutting assembly 4 cuts the film strip 100, the second lifting drive 13 drives the first pressure plate 12 to descend, causing the first pressure plate 12 to press the film strip 100 against the first pressure plate 11. Simultaneously, the fourth lifting drive 24 drives the second pressure plate 22 to descend, causing the second pressure plate 22 to press the film strip 100 against the second pressure plate 21. In this embodiment, since the second pressure plate 21 is fixed to the first mounting bracket 7, the second pressure plate 22 only needs to press the film strip 100 against the second pressure plate 21, and the fourth lifting drive 24 will not face the risk of impact damage.

[0118] After the cutting assembly 4 cuts the compressed film strip 100, the second lifting drive 13 first drives the first pressure plate 12 to rise and release the film strip 100. Subsequently, the first lifting drive 6 and the second lifting drive 13 synchronously drive the first bearing plate 11 and the first pressure plate 12 to rise, thereby causing the film strip 100, which is compressed by the first pressure plate 12 and the first bearing plate 11, to rise synchronously, ultimately causing the newly free end of the film strip 100, which has been cut, to be suspended between the second bearing plate 21 and the second pressure plate 22. In addition, during this process, a height difference is created between the newly free end of the film strip 100, which has been cut, and the external cutting platform, thereby avoiding contact and interference between the film strip traction mechanism and the cutting platform when performing the next traction.

[0119] The first lifting drive component 6, the second lifting drive component 13, and the fourth lifting drive component 24 can all be existing lifting drive devices such as cylinders or electric cylinders.

[0120] like Figure 1 As shown, in some embodiments, the cutting assembly 4 includes a first translational drive 42 and a cutter 41, wherein: the first translational drive 42 is mounted on a first mounting bracket 7, and the cutter 41 is connected to a movable part of the first translational drive 42. The first translational drive is configured to drive the cutter 41 to translate along a second direction (such as the Y direction), such that the cutter 41 passes through the gap between the second pressure plate 22 and the third pressure plate 31 to cut the compressed film strip 100, wherein the second direction is perpendicular to the first direction.

[0121] The first translation drive unit drives the cutter 41 to move through the gap between the second pressure plate 22 and the third pressure plate 31 to cut the compressed film strip 100, which can ensure the flatness of the film strip cutting edge.

[0122] The first translation drive 42 can be any existing linear drive with various structures that can drive the cutter 41 to translate along the second direction, such as a cylinder or an electric cylinder.

[0123] like Figures 1 to 3As shown, in some embodiments, the second pressing assembly 3 further includes a fifth lifting drive 32, which is mounted on the first mounting bracket 7. The third pressure plate 31 is connected to the movable part of the fifth lifting drive 32. The fifth lifting drive 32 is used to drive the third pressure plate 31 to rise or fall, so that the third pressure plate 31 presses or releases the membrane belt 100.

[0124] By setting the fifth lifting drive component 32, the lifting drive of the third pressure plate 31 is realized, so that the third pressure plate 31 can press the film strip 100 to the external cutting platform before the cutting component 4 cuts the film strip 100, and release the film after the cutting component 4 cuts the film strip 100 and obtains the film sheet.

[0125] Furthermore, integrating the fifth lifting drive component 32 onto the first mounting bracket 7 makes the structure of this application more concise and compact.

[0126] Of course, the fifth lifting drive 32 can also be set on a second mounting bracket that is independent of the first mounting bracket 7, and the first mounting bracket 7 and the second mounting bracket are configured to be close to or far from each other, so that the second pressure plate 22 and the third pressure plate 31 are close to or far from each other.

[0127] This configuration allows for flexible adjustment of the distance between the second pressure plate 22 and the third pressure plate 31, ensuring that both the second pressure plate 22 and the third pressure plate 31 can smoothly perform the pressing operation on the film strip 100. It also facilitates control of the gap between the second pressure plate 22 and the third pressure plate 31. In actual production, by controlling the gap between the second pressure plate 22 and the third pressure plate 31 to be small enough to allow the cutter to pass through, the cutting quality of the film strip by the cutter can be effectively guaranteed.

[0128] The fifth lifting drive component 32 can be an existing lifting drive device such as a cylinder or an electric cylinder.

[0129] like Figures 1 to 3 As shown, in some embodiments, the film tape pressing and cutting mechanism 10 further includes a second translation drive 8 and a base (not shown), wherein: the first mounting bracket 7 is slidably mounted on the base along a first direction, the first mounting bracket 7 is drively connected to the second translation drive 8 mounted on the base, and the second translation drive 8 is configured to drive the first mounting bracket 7 to translate along the first direction.

[0130] By setting up the second translation drive 8 and the base, the distance between the components on the first mounting frame 7 and the external cutting platform can be adjusted. Thus, when the components on the first mounting frame 7 are moved to a clearance position away from the cutting platform, they serve a clearance function, allowing the subsequent handling mechanism (e.g., a moving suction cup) to remove the film from the cutting platform. When the components on the first mounting frame 7 move to a working position close to the cutting platform, they can cooperate to perform pressing and cutting operations on the film strip 100. For example, the third pressure plate 31 can move above the end of the cutting platform, so that when the third pressure plate 31 descends, it can press the film strip 100 tightly against the end of the cutting platform.

[0131] This application also provides a film strip cutting device. For example... Figure 4 As shown, the film tape cutting device provided in this application includes a film tape traction mechanism 50 and a film tape feeding mechanism 30, a film tape pressing and cutting mechanism 10, and a cutting platform 40 arranged sequentially along a first direction (such as the X direction). The film tape pressing and cutting mechanism 10 is the film tape pressing and cutting mechanism 10 provided in any of the above embodiments, wherein:

[0132] The film tape feeding mechanism 30 is configured to carry the film tape roll 200 and drive the film tape roll 200 to rotate to feed the film tape 100.

[0133] The film strip 100 released from the film strip roll 200 passes sequentially through the first pressing assembly 1, the third pressing assembly 2 and the second pressing assembly 3 in the first direction and is clamped by the film strip traction mechanism 50, which is configured to pull the clamped film strip onto the cutting platform 40.

[0134] When the film belt is pulled onto the cutting platform 40, the first pressure plate 12 is configured to press the film belt 100 against the first pressure plate 11, the second pressure plate 22 is configured to press the film belt 100 against at least the second pressure plate 21, and the third pressure plate 31 is configured to press the film belt 100 against the first end of the cutting platform 40. The first end of the cutting platform 40 is the end of the cutting platform 40 near the film belt pressing and cutting mechanism 10.

[0135] The cutting assembly 4 is configured to cut the compressed film strip 100 from the gap between the second pressure plate 22 and the third pressure plate 31 to obtain a film sheet on the cutting platform 40.

[0136] After the membrane belt 100 is cut, the second pressure plate 22 is configured to rise to release the membrane belt 100. The second pressure plate 21 is configured to descend away from the membrane belt 100, or the first pressure plate 12 and the first pressure plate 22 are configured to drive the pressed membrane belt 100 to rise, such that the cut end of the membrane belt 100 is suspended between the second pressure plate 21 and the second pressure plate 22.

[0137] The optional operating process of the film tape cutting device provided in this application is as follows:

[0138] In the initial state, the first pressure plate 12 presses the film strip 100 released from the film strip roll 200 onto the first pressure plate 11, and the free end of the film strip 100 is suspended between the second pressure plate 21 and the second pressure plate 22. The third pressure plate 31 is located above the first end of the cutting platform 40.

[0139] After the membrane belt traction mechanism 50 clamps the free end of the membrane belt 100, the first pressure plate 12 rises to release the membrane belt 100.

[0140] After the traction mechanism 50 pulls the film strip 100 of a predetermined length onto the cutting platform 40, the third pressure plate 31 descends to press the film strip 100 against the first end of the cutting platform 40, and the first pressure plate 12 and the second pressure plate 22 descend to press the film strip 100 against the first end of the cutting platform 40. The bearing surfaces of the first pressure plate 11, the second pressure plate 21, and the cutting platform 40 are adjusted to be flush with each other in the height direction.

[0141] Subsequently, the cutting assembly 4 cuts the compressed film strip 100 between the second pressure plate 22 and the third pressure plate 31, thereby obtaining a film sheet located on the cutting platform 40.

[0142] Next, the second pressure plate 22 rises and resets to release the membrane belt 100, and the third pressure plate 31 rises and resets to release the membrane on the cutting platform 40.

[0143] Alternatively, the second pressure plate 21 may descend and detach from the membrane belt 100, or the second pressure plate 21 may remain stationary while the first pressure plate 12 and the first pressure plate 11 drive the compressed membrane belt 100 to rise, thereby causing the new free end of the membrane belt 100, which has been cut, to actively detach from the second pressure plate 21, so that the new free end of the membrane belt 100, which has been cut, is suspended between the second pressure plate 21 and the second pressure plate 22.

[0144] As can be seen, the membrane tape cutting device provided in this application can ensure the horizontality of the pressed membrane tape 100 because the pressing surfaces of the second pressure plate 22 and the second bearing plate 21 are both flat, thereby ensuring that the cutting assembly 4 obtains a straight cutting edge after cutting the membrane tape 100, and ultimately avoiding wavy patterns on both sides of the membrane.

[0145] Furthermore, after obtaining the diaphragm, the second pressure plate 22 and the second bearing plate 21 are controlled to rise and fall in opposite directions. Alternatively, the second pressure plate 22 is first controlled to rise and release the membrane belt 100, and then the first pressing assembly 1 is controlled to drive the pressed membrane belt 100 to rise. This allows the new free end of the membrane belt 100, which has been cut, to be exposed to the membrane belt pressing and cutting mechanism 10, so that the traction mechanism 50 can smoothly clamp the free end of the membrane belt 100 when performing the next traction.

[0146] Of course, the specific implementation method used to expose the new free end of the membrane tape 100 after cutting depends on the specific structure of the membrane tape pressing and cutting mechanism 10.

[0147] For example, when the membrane belt pressing and cutting mechanism 10 is Figures 1 to 3 In the structure described in the embodiment, by controlling the second pressure plate 22 and the second bearing plate 21 to rise and fall in opposite directions, the new free end of the membrane belt 100, which is generated by cutting, is suspended between the second bearing plate 21 and the second pressure plate 22.

[0148] When the membrane tape pressing and cutting mechanism 10 has the structure of another embodiment described above, the pressed membrane tape 100 is driven to rise by the first pressing component 1, so that the new free end of the membrane tape 100 after cutting is suspended between the second pressure plate 21 and the second pressure plate 22.

[0149] In some embodiments, the distance between the cutting platform 40 and the second pressure plate 21 in the film tape pressing and cutting mechanism 10 is adjustable in the first direction.

[0150] For example, before the traction mechanism 50 pulls the film strip 100 to the cutting platform 40, it can adjust the distance between the cutting platform 40 and the second pressure plate 21 to a smaller first distance, thereby ensuring that the traction mechanism 50 can smoothly clamp the free end of the film strip 100 from the film strip pressing and cutting mechanism 10, and pull the film strip 100 of a predetermined length to the cutting platform 40, and ensure that the first pressing assembly 1, the third pressing assembly 2 and the cutting assembly 4 can cooperate with the second pressing assembly 3 to complete the pressing and cutting of the film strip 100.

[0151] After the cutting assembly 4 completes the cutting of the film strip 100, the distance between the cutting platform 40 and the second pressure plate 21 can be adjusted to a larger second distance, so that the subsequent handling mechanism (e.g., a moving suction cup) can remove the film strip from the cutting platform 40, and avoid the handling mechanism (e.g., a moving suction cup) from contacting and interfering with the cutting platform 40.

[0152] As described above, in an optional embodiment of the film tape pressing and cutting mechanism 10, the first mounting bracket 7 is slidably mounted on the base along a first direction. The first mounting bracket 7 is drively connected to a second translational drive member 8 mounted on the base, and the second translational drive member 8 can drive the first mounting bracket 7 to translate along the first direction. When using the film tape pressing and cutting mechanism 10 in this embodiment, the distance between the cutting platform 40 and the second pressure plate 21 can be adjusted by driving the first mounting bracket 7 to translate toward or away from the cutting platform 40 through the second translational drive member 8.

[0153] Alternatively, the cutting platform 40 can be mounted on an additional translation drive device, which drives the cutting platform 40 to translate in the first direction to adjust the distance between the cutting platform 40 and the second pressure plate 21.

[0154] In some embodiments, the cutting platform 40 and the second pressure plate 21 in the film tape pressing and cutting mechanism 10 may be offset from or aligned with each other in the height direction.

[0155] After the traction mechanism 50 pulls the film strip 100 of a predetermined length onto the cutting platform 40, it adjusts the cutting platform 40 and the second pressure plate 21 to be aligned with each other in the height direction, thereby ensuring that the first pressing assembly 1, the third pressing assembly 2 and the cutting assembly 4 can cooperate with the second pressing assembly 3 to complete the pressing and cutting of the film strip 100.

[0156] After the cutting assembly 4 completes the cutting of the film belt 100, the cutting platform 40 and the second pressure plate 21 can be adjusted to be staggered, so that a height difference is generated between the free end of the film belt 100 and the cutting platform 40, so as to avoid the traction mechanism 50 from touching and interfering with the cutting platform 40 when performing the next traction.

[0157] In some embodiments, when the height of the second pressure plate 21 is not adjustable, the cutting platform 40 can be mounted on an additional lifting drive device. The cutting platform 40 can be raised and lowered by the lifting drive device, so that the cutting platform 40 and the second pressure plate 21 are aligned or staggered in the height direction.

[0158] like Figure 5 As shown, in some embodiments, the film tape traction mechanism 50 includes a drive unit 51 and a clamping assembly 52, wherein the clamping assembly 52 is connected to the movable part of the drive unit 51, the clamping assembly 52 is used to clamp the film tape 100, and the drive unit 51 is at least used to drive the clamping assembly 52 to translate in a first direction, so as to drive the clamping assembly 52 to clamp the free end of the film tape 100 from the film tape pressing and cutting mechanism 10, and pull the clamped film tape 100 onto the cutting platform 40.

[0159] The clamping assembly 52 includes a lower clamping plate 521 and an upper clamping plate 522 that can be clamped together vertically, wherein: the clamping surface of the lower clamping plate 521 is a plane. The clamping surface of the upper clamping plate 522 is a plane, or the upper clamping plate 522 is provided with a plurality of pressure teeth.

[0160] When the upper clamping plate 522 and the lower clamping plate 521 are clamped together, the membrane belt 100 is clamped. When the upper clamping plate 522 and the lower clamping plate 521 are separated, the membrane belt 100 is released.

[0161] Setting the clamping surface of the lower clamping plate 521 to a plane can improve the straightness of the free end of the membrane belt 100 and prevent wrinkles from appearing at the free end of the membrane belt 100.

[0162] like Figure 5 As shown, in some embodiments, the drive unit 51 includes a translation drive assembly 511 and a lifting drive assembly 512, wherein the lifting drive assembly 512 is connected to a movable part of the translation drive assembly 511, and the clamping assembly 52 is connected to a movable part of the lifting drive assembly 512. The translation drive assembly 511 is used to drive the clamping assembly 52 to move along a first direction, while the lifting drive assembly 512 is used to drive the clamping assembly 52 to rise and fall.

[0163] The translation drive assembly 511 drives the clamping assembly 52 to grip the free end of the film strip 100 from the film strip pressing and cutting mechanism 10, and pulls the film strip 100 of a predetermined length onto the cutting platform 40 along the first direction. The clamping assembly 52 is connected to the movable part of the lifting drive assembly 512. After the clamping assembly 52 pulls the film strip 100 above the cutting platform 40, the clamping assembly 52 descends to a low position under the drive of the lifting drive assembly 512, thereby laying the film strip 100 onto the cutting platform 40.

[0164] After the cutting component 4 cuts the film strip 100, the clamping component 52 is driven by the lifting drive component 512 to rise to a high position above the cutting platform 40. In this way, when the film strip 100 is pulled again, the clamping component 52 can pass over the cutting platform 40 to clamp the free end of the film strip 100, preventing collision with the cutting platform 40.

[0165] Of course, in the case where the cutting platform 40 is installed on the lifting drive device, that is, when the cutting platform 40 can be raised and lowered by the lifting drive device, the drive unit 51 of the film belt traction mechanism 50 can only perform translation drive of the clamping component 52, without performing lifting drive of the clamping component 52. In other words, the drive unit 51 can only include the translation drive component 511.

[0166] After the clamping assembly 52 pulls the film strip above the cutting platform 40, the cutting platform 40 rises to a high position, allowing the film strip 100 to be laid on the cutting platform 40. After the cutting assembly 4 cuts the film strip 100, the cutting platform 40 descends to a low position, causing the clamping assembly 52 to be higher than the cutting platform 40.

[0167] like Figure 4As shown, in some embodiments, the membrane belt traction mechanism 50 further includes a pressure plate 523, a pressure plate drive member 524, and a rotating shaft 525, wherein: the rotating shaft 525 is disposed on the lower clamping plate 521, the upper clamping plate 522 is rotatably connected to the rotating shaft 525, a compression spring is disposed between the first end of the upper clamping plate 522 and the lower clamping plate 521, and the second end of the upper clamping plate 522 is a clamping end. The pressure plate drive member 524 is disposed on the lower clamping plate 521, the pressure plate 523 is connected to the movable part of the pressure plate drive member 524, and the pressure plate drive member 524 is configured to drive the pressure plate 523 to move toward or away from the upper clamping plate 522.

[0168] When the pressure plate drive 524 drives the pressure plate 523 to move toward the upper clamping plate 522, the pressure plate 523 drives the first end of the upper clamping plate 522 to move downward, and a clamping gap is formed between the clamping end of the upper clamping plate 522 and the lower clamping plate 521 for the film belt 100 to enter, and the compression spring is compressed.

[0169] When the pressure plate drive 524 drives the pressure plate 523 to move away from the upper clamping plate 522, the pressure spring loses pressure and rebounds, and the clamping end of the upper clamping plate 522 presses the film belt 100 onto the lower clamping plate 521.

[0170] 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.
