Abstract

The utility model provides a film belt cutting mechanism. The film belt cutting mechanism comprises a feeding part, a pressing and cutting part, a bearing table and a traction part. The pressing and cutting-off part is located between the feeding part and the bearing table, and the traction part is configured to clamp the film belt from the pressing and cutting-off part and drag the clamped film belt to the bearing table in the first direction. The pressing and cutting-off part comprises a first pressing assembly, a cutting-off assembly and a second pressing assembly which are sequentially arranged in the first direction. The first pressing assembly and the second pressing assembly press the film belt from the two sides of the cutting-off assembly, and the cutting-off assembly is configured to cut off the pressed film belt between the first pressing assembly and the second pressing assembly so as to obtain a film belt section located on the bearing table. The first end of the bearing table is the end, close to the pressing and cutting-off part, of the bearing table. Due to the fact that when the cutting-off assembly cuts off the film belt, the first pressing assembly and the second pressing assembly press the film belt from the positions close to the two sides of the cutting-off assembly, the film belt is completely tightened when cut off, and finally it is guaranteed that the film belt section with the straight edge is obtained.

Description

Technical Field

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

[0002] In the production process of photovoltaic modules, it is often necessary to use a film and tape cutting mechanism to cut film and tape segments of predetermined lengths from the film and tape roll.

[0003] Existing film strip cutting mechanisms generally include components such as a feeding section, a pressing section, a cutting section, a support platform, and a traction section. The film strip released by the feeding section passes sequentially through the pressing section and the cutting section. The traction section clamps the free end of the film strip from the cutting section and pulls the film strip of a predetermined length onto the support platform. Subsequently, the pressing section presses the film strip, and the cutting section cuts the film strip to obtain film strip segments.

[0004] Existing film strip cutting mechanisms only press the film strip from a position adjacent to the first side of the cutting section using the clamping part, while the traction part presses the film strip from a position further away on the second side of the cutting section. Therefore, when the cutting part cuts the film strip, the film strip is not fully taut, making it impossible to form a straight cut, ultimately resulting in the inability to obtain film strip segments with straight edges. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a film tape cutting mechanism, the detailed technical solution of which is as follows:

[0006] A film tape cutting mechanism includes a feeding section, a pressing and cutting section, a support platform, and a traction section, wherein:

[0007] The feeding unit is configured to release the film strip, the clamping and cutting unit is located between the feeding unit and the support table, the clamping and cutting unit is configured to clamp the film strip released by the feeding unit, the traction unit is configured to clamp the free end of the film strip from the clamping and cutting unit, the clamping and cutting unit releases the clamped film strip, and the traction unit pulls the clamped film strip onto the support table in the first direction.

[0008] The clamping and cutting section includes a mounting frame and a first clamping assembly, a cutting assembly, and a second clamping assembly sequentially arranged on the mounting frame along a first direction. The first clamping assembly is configured to clamp the film strip from a first side of the cutting assembly, the second clamping assembly is configured to clamp the film strip to a first end of the support platform from a second side of the cutting assembly, and the cutting assembly is configured to cut the clamped film strip between the first clamping assembly and the second clamping assembly to obtain a film strip segment located on the support platform.

[0009] The first end of the support platform is the end of the support platform that is close to the clamping and cutting part.

[0010] The membrane tape cutting mechanism provided in this application includes a pressing and cutting part comprising a first pressing component, a cutting component, and a second pressing component arranged sequentially along the traction direction of the membrane tape. When the cutting component cuts the membrane tape, the first pressing component and the second pressing component press the membrane tape from adjacent positions on both sides of the cutting component, thereby making the membrane tape fully taut when it is cut, thus forming a straight cut and ultimately ensuring that a membrane tape segment with a straight edge is obtained.

[0011] In some embodiments, the first pressing assembly includes a pressure plate, a first pressure plate, and a first lifting drive module, wherein: the pressure plate is disposed on a mounting frame; the first lifting drive module is disposed on the mounting frame, the first pressure plate is connected to a movable part of the first lifting drive module, and the first pressure plate is located above the pressure plate; the film strip passes between the first pressure plate and the pressure plate, and the first lifting drive module is used to drive the first pressure plate to lift and lower, so as to press the film strip onto the pressure plate or release the film strip from the first side of the cutting assembly.

[0012] A first pressing assembly with a simple structure and fast response speed is provided. It drives the first pressure plate to move up or down toward or away from the pressure plate through a first lifting drive module, thereby realizing the rapid pressing and release of the membrane strip passing between the first pressure plate and the pressure plate.

[0013] In some embodiments, the second pressing assembly includes a second pressure plate and a second lifting drive module, wherein: the second lifting drive module is disposed on the mounting frame, and the second pressure plate is connected to a movable part of the second lifting drive module; the second lifting drive module is used to drive the second pressure plate to lift and lower, so as to press the film strip to the first end of the support platform from the second side of the cutting assembly or release the film strip.

[0014] A second pressing assembly with a simple structure and fast response speed is provided. It drives the second pressure plate to move up or down toward or away from the first end of the support platform through the second lifting drive module, thereby pressing the film strip to the first end of the support platform or releasing the film strip from the second side of the cutting assembly.

[0015] In some embodiments, the cutting assembly includes a first translation drive module and a cutter, wherein: the first translation drive module is disposed on a mounting bracket, and the cutter is connected to a movable part of the first translation drive module; the first translation drive module is used to drive the cutter to translate along a second direction to cut the film strip located on the translation path of the cutter, wherein the second direction is perpendicular to the first direction.

[0016] The first translation drive module drives the cutter to pass through the translation path of the cutter from the side of the film strip to cut the film strip. On the one hand, it can ensure the complete cutting of the film strip, and on the other hand, it eliminates the need to set up a cutting plate corresponding to the cutter, thus making the structure of the cutting assembly simpler.

[0017] In some embodiments, the clamping and cutting part further includes a base and a second translation drive module, wherein: the base is disposed on the movable part of the second translation drive module, and the mounting bracket is disposed on the base; the second translation drive module is used to drive the base to translate along a first direction, so as to drive the base to switch between a working position close to the support platform and a clearance position away from the support platform; when the base is switched to the working position, the second clamping component is located above the first end of the support platform; when the base is switched to the clearance position, the second clamping component is located on the first side of the support platform.

[0018] When the base is switched to the avoidance position, the base and all its components are moved away from the carrier platform to avoid the carrier platform, so that the subsequent membrane strip transport mechanism (such as a moving suction cup) can remove the membrane strip from the carrier platform.

[0019] When the base is switched to the working position, the second clamping component is located above the first end of the support platform. In this way, when the second clamping component is pressed down, it can press the membrane belt to the first end of the support platform.

[0020] In some embodiments, the mounting frame includes a first mounting bracket, a second mounting bracket, and a third lifting drive module, wherein: the first mounting bracket is disposed on a base, the second mounting bracket is slidably and vertically connected to the first mounting bracket, a first clamping component and a second clamping component are both disposed on the second mounting bracket, and a cutting component is disposed on the first mounting bracket; the third lifting drive module is disposed on the base or the first mounting bracket, and the third lifting drive module is used to drive the second mounting bracket to move up and down between a first high position and a first low position; the third lifting drive module is configured to drive the second mounting bracket down to the first low position to tension the membrane strip to the first end of the support platform; the third lifting drive module is also configured to drive the second mounting bracket up to the first high position, such that the new free end of the membrane strip after cutting is higher than the support platform.

[0021] The first and second clamping components are mounted on a liftable second mounting bracket driven by a third lifting drive module. When the traction unit pulls the film strip onto the support platform, the second mounting bracket descends to its first low position. During this process, the first clamping component lowers the clamped film strip, causing it to tension at the first end of the support platform, thus improving the cutting effect of the cutting component. After the cutting component cuts the film strip, the second mounting bracket needs to be raised to its first high position, and the first clamping component raises the clamped film strip so that the new free end of the film strip after cutting is higher than the support platform, facilitating the traction unit to grip the new free end of the film strip during the next cut.

[0022] In some embodiments, the traction unit includes a third translation drive module, a fourth lifting drive module, and a clamping assembly, wherein: the fourth lifting drive module is connected to a movable part of the third translation drive module, and the clamping assembly is connected to a movable part of the fourth lifting drive module; the third translation drive module is used to drive the clamping assembly to move along a first direction, so as to drive the clamping assembly to clamp the free end of the film strip from the pressing and cutting part, and to pull the film strip along the first direction to the support platform; the fourth lifting drive module is used to drive the clamping assembly to move up and down between a second high position and a second low position; after the clamping assembly pulls the film strip above the support platform, the fourth lifting drive module drives the clamping assembly to descend to the second low position, so that the film strip is tensioned to the second end of the support platform; after the cutting assembly cuts the film strip, the fourth lifting drive module drives the clamping assembly to rise to the second high position, so that the clamping assembly is higher than the support platform; the second end of the support platform is the end of the support platform away from the pressing and cutting part.

[0023] By incorporating a third translational drive module, the gripping assembly can move along a first direction to grip the free end of the film strip from the clamping and cutting section, and pull the film strip onto the support platform along the first direction. The gripping assembly is connected to the movable part of a fourth lifting drive module. After the gripping assembly pulls the film strip above the support platform, it descends to a second low position under the drive of the fourth lifting drive module, thereby tensioning the film strip to the second end of the support platform. This further enhances the cutting effect of the cutting assembly on the film strip. After the cutting assembly cuts the film strip, the gripping assembly rises to a second high position under the drive of the fourth lifting drive module, exceeding the support platform. This allows the gripping assembly to pass over the support platform to grip the free end of the film strip during the next cut.

[0024] In some embodiments, the support platform is provided with adsorption holes for adsorbing the film belt, and the second end of the support platform is provided with a clearance groove for avoiding the traction part; the second end of the support platform is the end of the support platform away from the pressing and cutting part.

[0025] By setting adsorption holes on the support platform, the cut membrane strip segments are adsorbed and fixed on the support platform, ensuring that the subsequent membrane strip segment transport mechanism can smoothly retrieve the membrane strip segments from the support platform. Furthermore, by setting a clearance groove at the second end of the support platform, the second end of the support platform can avoid the traction unit, allowing the membrane strip to adhere tightly to the support platform, with the free end of the membrane strip located on the platform surface.

[0026] In some embodiments, the support platform includes a base, a first support plate, and a second support plate, wherein the first support plate and the second support plate are connected side by side on the base along a first direction, at least one of the first support plate and the second support plate is configured to be movable relative to the other along the first direction, and the first support plate and the second support plate are used together to support the film strip.

[0027] By controlling the relative movement of the first and second bearing plates, the size of the bearing surface of the bearing platform can be flexibly adjusted, enabling the bearing platform to support film strips of different lengths to be cut, thereby achieving compatibility.

[0028] In some embodiments, the feeding unit includes a roller drive, a feeding roller, and a guide roller assembly, wherein: the driving end of the roller drive is connected to the feeding roller, the roller drive is configured to drive the feeding roller to rotate, and the feeding roller is used to mount the film strip roll; the guide roller assembly is disposed between the feeding roller and the pressing and cutting unit, and the guide roller assembly is used to guide the film strip released from the film strip roll into the pressing and cutting unit.

[0029] By configuring the feeding section, the feeding section can automatically release the film belt and ensure that the film belt can smoothly enter the pressing and cutting section. Attached Figure Description

[0056] To make the above-mentioned objectives, 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.

[0057] As described in the background section, existing membrane tape cutting mechanisms only press the membrane tape from a position adjacent to the first side of the cutting section by the pressing part, while the traction part presses the membrane tape at a position farther away from the second side of the cutting section. Therefore, when the cutting part cuts the membrane tape, the membrane tape is not fully taut, thus failing to form a straight cut, ultimately resulting in the inability to obtain membrane tape segments with straight edges.

[0058] To address the aforementioned issues, this application provides a film strip cutting mechanism that can press the film strip from adjacent positions on both sides of the cutting assembly, so that the film strip is fully taut when it is cut, thereby forming a straight cut and ultimately ensuring that a film strip segment with a straight edge is obtained.

[0059] like Figures 1 to 5 As shown, the film tape cutting mechanism of this application includes a feeding unit 1, a pressing and cutting unit 2, a support platform 3, and a traction unit 4, wherein:

[0060] The feeding unit 1 is configured to release the film strip, the clamping and cutting unit 2 is located between the feeding unit 1 and the support table 3, the clamping and cutting unit 2 is configured to clamp the film strip released by the feeding unit 1, the traction unit 4 is configured to clamp the free end of the film strip from the clamping and cutting unit 2, the clamping and cutting unit 2 releases the clamped film strip, and the traction unit 4 pulls the clamped film strip onto the support table 3 along the first direction.

[0061] The clamping and cutting section 2 includes a mounting frame 21 and a first clamping assembly 22, a cutting assembly 23, and a second clamping assembly 24 sequentially arranged on the mounting frame 21 along a first direction (e.g., the X direction). The first clamping assembly 22 is configured to clamp the film strip from a first side of the cutting assembly 23. The second clamping assembly 24 is configured to clamp the film strip to a first end of the support platform 3 from a second side of the cutting assembly 23. The cutting assembly 23 is configured to cut the clamped film strip between the first clamping assembly 22 and the second clamping assembly 24 to obtain a film strip segment located on the support platform 3. The first end of the support platform 3 is the end of the support platform 3 closest to the clamping and cutting section 2.

[0062] The optional working process of the film strip cutting mechanism in this application embodiment is as follows:

[0063] The traction unit 4 clamps the free end of the film strip from the clamping and cutting unit 2, and the clamping and cutting unit 2 then releases the film strip. The traction unit 4 pulls the clamped film strip along the first direction, so that the film strip of a predetermined length passes through the first clamping assembly 22, the cutting assembly 23 and the second clamping assembly 24 in sequence and enters the support table 3.

[0064] Subsequently, the first pressing assembly 22 presses the film strip from the first side of the cutting assembly 23, while the second pressing assembly 24 presses the film strip from the second side of the cutting assembly 23 to the first end of the support platform 3.

[0065] The cutting assembly 23 cuts the compressed film strip between the first pressing assembly 22 and the second pressing assembly 24, thereby obtaining a film strip segment located on the support platform 3.

[0066] The film strip cutting mechanism provided in this application includes a clamping and cutting section 2 comprising a first clamping assembly 22, a cutting assembly 23, and a second clamping assembly 24 arranged sequentially along the traction direction of the film strip. When the cutting assembly 23 cuts the film strip, the first clamping assembly 22 and the second clamping assembly 24 clamp the film strip from adjacent positions on both sides of the cutting assembly 23, so that the film strip is fully taut when cut, thereby forming a straight cut and ultimately ensuring that a film strip segment with a straight edge is obtained.

[0067] like Figures 1 to 2As shown, optionally, the feeding unit 1 includes a roller drive 11, a feeding roller 12, and a guide roller assembly 13, wherein: the driving end of the roller drive 11 is connected to the feeding roller 12, and the roller drive 11 is configured to drive the feeding roller 12 to rotate; the feeding roller 12 is used to mount the film strip roll. The guide roller assembly 13 is disposed between the feeding roller 12 and the pressing and cutting unit 2, and the guide roller assembly 13 is used to guide the film strip released from the film strip roll into the pressing and cutting unit 2. The feeding roller 12 can be an air-expanding shaft, which can be inserted into the hollow part inside the film strip roll.

[0068] By configuring the feeding section 1, the feeding section 1 can automatically release the film belt and ensure that the film belt can smoothly enter the pressing and cutting section 2.

[0069] Roller drive 11 can be any existing rotary drive that can drive the feed roller 12 to rotate, for example... Figure 1 As shown, the roller drive 11 includes a first motor 111, a drive pulley, a first belt 112, and a driven pulley. The drive pulley is connected to the drive shaft of the motor, and the driven pulley is connected to the end of the feeding roller 12. The first belt 112 is sleeved on the drive pulley and the driven pulley. The first motor 111 drives the drive pulley to rotate, thereby driving the feeding roller 12 to rotate via the first belt 112 and the driven pulley.

[0070] like Figures 4 to 5 As shown, optionally, the first pressing assembly 22 includes a pressure plate 221, a first pressure plate 222, and a first lifting drive module 223, wherein: the pressure plate 221 is mounted on the mounting frame 21. The first lifting drive module 223 is mounted on the mounting frame 21, and the first pressure plate 222 is connected to the movable part of the first lifting drive module 223, with the first pressure plate 222 located above the pressure plate 221. The membrane tape passes between the first pressure plate 222 and the pressure plate 221, and the first lifting drive module 223 is used to drive the first pressure plate 222 to rise and fall. When the first lifting drive module 223 drives the first pressure plate 222 to descend toward the pressure plate 221, it presses the membrane tape onto the pressure plate 221. When the first lifting drive module 223 drives the first pressure plate 222 to rise away from the pressure plate 221, the first pressure plate 222 releases the membrane tape.

[0071] The first lifting drive module 223 can be any existing linear drive module capable of driving the first pressure plate 222 to lift, such as a cylinder, a motor, or a lead screw and nut mechanism.

[0072] Optionally, the second pressing assembly 24 includes a second pressure plate 241 and a second lifting drive module 242, wherein: the second lifting drive module 242 is mounted on the mounting bracket 21, and the second pressure plate 241 is connected to a movable part of the second lifting drive module 242. The second lifting drive module 242 is used to drive the second pressure plate 241 to rise and fall, so as to press the film strip onto the first end of the support platform 3 from the second side of the cutting assembly 23 or release the film strip.

[0073] Similarly, the second lifting drive module 242 can adopt various existing linear drive modules that can drive the second pressure plate 241 to lift, such as cylinder drive modules, lead screw drive modules, etc.

[0074] like Figures 4 to 5 As shown, optionally, the cutting assembly 23 includes a first translation drive module 231 and a cutter 232, wherein: the first translation drive module 231 is disposed on the mounting bracket 21, and the cutter 232 is connected to a movable part of the first translation drive module 231. The first translation drive module 231 is used to drive the cutter 232 to translate along a second direction (such as the Y direction) to cut the film strip located on the translation path of the cutter 232, wherein the second direction is perpendicular to the first direction.

[0075] The first translation drive module 231 drives the cutter 232 to pass through the translation path of the cutter 232 from the side of the film strip to cut the film strip. On the one hand, it can ensure the complete cutting of the film strip, and on the other hand, there is no need to set up a cutting plate corresponding to the cutter 232, thus making the structure of the cutting assembly 23 simpler.

[0076] like Figure 5 As shown, optionally, the clamping and cutting section 2 further includes a base 25 and a second translation drive module 26, wherein: the base 25 is disposed on the movable part of the second translation drive module 26, and the mounting bracket 21 is disposed on the base 25. The second translation drive module 26 is used to drive the base 25 to translate along a first direction, thereby switching the base 25 between a working position close to the support platform 3 and a clearance position away from the support platform 3. When the base 25 is switched to the working position, the second clamping assembly 24 is located above the first end of the support platform 3, and the film strip can be clamped onto the first end of the support platform 3 by the second pressure plate 241 in the second clamping assembly 24. When the cutting assembly 23 cuts the film strip and obtains the film strip segment, it can control the base 25 to move to the clearance position. In this position, the second clamping assembly 24 is located on the first side of the support platform 3, and the base 25 and all its components are away from the support platform 3, thus playing a clearance role, so that the subsequent film strip segment transport mechanism (e.g., a moving suction cup) can remove the film strip segment from the support platform 3.

[0077] The second translation drive module 26 can be any existing linear drive module capable of driving the base 25 to translate between the working position and the avoidance position, such as a cylinder, a motor with a lead screw and nut, etc.

[0078] like Figures 4 to 6 As shown, the mounting bracket 21 includes a first mounting bracket 211, a second mounting bracket 212, and a third lifting drive module 213. The first mounting bracket 211 is mounted on the base 25. The second mounting bracket 212 is slidably and vertically connected to the first mounting bracket 211. A first clamping assembly 22 and a second clamping assembly 24 are both mounted on the second mounting bracket 212. A cutting assembly 23 is mounted on the first mounting bracket 211. The third lifting drive module 213 is mounted on either the base 25 or the first mounting bracket 211. The third lifting drive module 213 drives the second mounting bracket 212 to move up and down between a first high position and a first low position.

[0079] The third lifting drive module 213 is configured to drive the second mounting bracket 212 down to a first low position to tension the membrane strip to the first end of the support platform 3. The third lifting drive module 213 is also configured to drive the second mounting bracket 212 up to a first high position, such that the new free end of the membrane strip after cutting is higher than the support platform 3.

[0080] As can be seen, the first clamping assembly 22 and the second clamping assembly 24 are mounted on the liftable second mounting bracket 212 driven by the third lifting drive module 213. When the traction unit 4 pulls the film strip onto the support platform 3, the first clamping assembly 22 can drive the clamped film strip to descend, thereby tensioning the film strip to the first end of the support platform 3, thus improving the cutting effect of the cutting assembly 23 on the film strip. After the cutting assembly 23 cuts the film strip, the second pressure plate 241 is first controlled to rise by the second lifting drive module 242, so that the second pressure plate 241 moves away from the support platform 3. At the same time, the traction unit 4 releases the film strip segment, and the second translation drive module 26 drives the base 25 to translate along the first direction, so that the base 25 moves to a clearance position away from the support platform 3. The film strip segment is removed from the support platform 3 by the film strip segment transport mechanism. After that, the second translation drive module 26 drives the base 25 to move to a working position close to the support platform 3, and the third lifting drive module 213 drives the second Mounting bracket 212 rises to its highest position, raising the new free end of the membrane strip above the support platform 3. This allows the traction unit 4 to pull the new free end of the membrane strip into place, attaching it to the support platform 4. Simultaneously, the third lifting drive module 213 drives the second mounting bracket 212 to descend to its lowest position, tensioning the membrane strip to the first end of the support platform 3. Then, the second lifting drive module 242 controls the second pressure plate 241 to descend until it presses the membrane strip firmly against the first end of the support platform 3. Finally, the cutting assembly 23 cuts the membrane strip. This cycle repeats to achieve membrane strip cutting.

[0081] The third lifting drive module 213 can be any existing linear drive module capable of driving the second mounting bracket 212 to lift, such as a cylinder, a motor, or a lead screw and nut mechanism.

[0082] like Figure 3 As shown, the traction unit 4 includes a third translation drive module 41, a fourth lifting drive module 42, and a clamping assembly 43, wherein: the fourth lifting drive module 42 is connected to the movable part of the third translation drive module 41, and the clamping assembly 43 is connected to the movable part of the fourth lifting drive module 42. The third translation drive module 41 is used to drive the clamping assembly 43 to move along a first direction, so as to drive the clamping assembly 43 to clamp the free end of the film strip from the pressing and cutting part 2, and to pull the film strip along the first direction onto the support platform 3. The fourth lifting drive module 42 is used to drive the clamping assembly 43 to move up and down between a second high position and a second low position.

[0083] After the clamping assembly 43 pulls the film strip above the support platform 3, the fourth lifting drive module 42 drives the clamping assembly 43 to descend to the second lowest position, causing the film strip to be tensioned to the second end of the support platform 3. After the cutting assembly 23 cuts the film strip, the fourth lifting drive module 42 drives the clamping assembly 43 to rise to the second highest position, causing the clamping assembly 43 to be higher than the support platform 3. The second end of the support platform 3 is the end of the support platform 3 away from the pressing and cutting part 2.

[0084] As can be seen, the translational drive of the third translational drive module 41 enables the drive gripping assembly 43 to move along the first direction, gripping the free end of the film strip from the pressing and cutting part 2, and pulling the film strip along the first direction onto the support platform 3. Since the gripping assembly 43 is connected to the movable part of the fourth lifting drive module 42, after the gripping assembly 43 pulls the film strip above the support platform 3, the gripping assembly 43 descends to the second low position under the drive of the fourth lifting drive module 42, thereby tensioning the film strip to the second end of the support platform 3. This further improves the cutting effect of the cutting assembly 23 on the film strip. After the cutting assembly 23 cuts the film strip, the gripping assembly 43 rises to the second high position under the drive of the fourth lifting drive module 42 to be above the support platform 3. Thus, during the next cutting, the gripping assembly 43 can pass over the support platform 3 to grip the free end of the film strip, preventing collision with the support platform 3.

[0085] Figure 3In the illustrated embodiment, the third translation drive module 41 includes a second motor 411, a second belt 412, and a third mounting bracket 413. The fourth lifting drive module 42 includes a cylinder 421 and a fourth mounting bracket 422. The third mounting bracket 413 is slidably connected to a horizontal slide rail extending in a first direction and connected to one side of the second belt 412 (the lower side belt). The second motor 411 drives the second belt 412 to rotate, thereby causing the third mounting bracket 413 to slide in the first direction. The fourth mounting bracket 422 is slidably and vertically connected to the third mounting bracket 413 and connected to the drive end of the cylinder 421 mounted on the third mounting bracket 413. A clamping assembly 43 is mounted on the fourth mounting bracket 422, and the cylinder 421 drives the fourth mounting bracket 422 to slide vertically relative to the third mounting bracket 413.

[0086] Of course, the third translation drive module 41 and the fourth lifting drive module 42 can also adopt other existing linear drive modules, as long as they can cooperate with each other to drive the clamping component 43 to translate along the first direction and to lift along the vertical direction.

[0087] like Figure 7 As shown, optionally, the clamping assembly 43 includes a fifth mounting frame 431, a support plate 432, a fifth lifting drive module 434, a pressure plate 435, and a plurality of clamps 433, wherein: the support plate 432 is fixedly mounted on the fifth mounting frame 431, and the plurality of clamps 433 are rotatably connected to the fifth mounting frame 431. The fifth lifting drive module 434 is mounted on the fifth mounting frame 431, and the pressure plate 435 is connected to the drive end of the fifth mounting frame 431 and is located above the plurality of clamps 433.

[0088] In the initial state, the clamping ends of several clamps 433 are elastically pressed against the support plate 432. When it is necessary to clamp the free end of the film strip, the fifth lifting drive module 434 first drives the pressure plate 435 to descend. The pressure plate 435 presses down on the tail ends of several clamps 433, thereby forming a clamping gap between the clamping ends of several clamps 433 and the support plate 432 to accommodate the free end of the film strip. When the free end of the film strip enters the clamping gap, the fifth lifting drive module 434 drives the pressure plate 435 to rise. The pressure plate 435 disengages from the tail ends of several clamps 433, and the clamping ends of several clamps 433 reset, thereby pressing the free end of the film strip against the support plate 432. Of course, the clamping assembly 43 can also use other existing clamping mechanisms, as long as they can clamp the free end of the film strip.

[0089] like Figure 3As shown, optionally, the support platform 3 is provided with adsorption holes 31 for adsorbing the film strip, and the second end of the support platform 3 is provided with a clearance groove 32 for avoiding the traction part 4. The second end of the support platform 3 is the end of the support platform 3 away from the pressing and cutting part 2. Specifically, the number of clearance grooves 32 is the same as the number of clamps 433. By providing clearance grooves 32 at the second end of the support platform 3, when the clamping assembly 43 descends to the second low position under the drive of the fourth lifting drive module 42, the clamps 433 are arranged in the corresponding clearance grooves 32 to ensure that the edge of the film strip is flush with the edge of the second end of the support platform 3, and to avoid the film strip being suspended outside the support platform 3, which would cause the film strip to bend.

[0090] Specifically, the support platform 3 has a vacuum channel inside, and the adsorption hole 31 is connected to the vacuum channel. The vacuum channel is also connected to a vacuum pump. When the vacuum pump is running, it can generate an adsorption force at the adsorption hole 31, and the support platform 3 adsorbs the membrane strip segment through the adsorption hole 31. By setting the adsorption hole 31 on the support platform 3, the cut membrane strip segment is adsorbed and fixed on the support platform 3. When the vacuum pump is stopped, the adsorption force at the adsorption hole 31 is lost, and the subsequent membrane strip segment transport mechanism can smoothly obtain the membrane strip from the support platform 3. Furthermore, by setting the avoidance groove 32 at the second end of the support platform 3, the second end of the support platform 3 can avoid the traction part 4, so that the membrane strip can adhere tightly to the support platform 3, and the free end of the membrane strip is located on the platform surface of the support platform 3. Alternatively, a vacuum generator or the like can be used to generate an adsorption force at the adsorption hole 31.

[0091] like Figure 3 As shown, optionally, the support platform 3 includes a base 33, a first support plate 34 and a second support plate 35, wherein: the first support plate 34 and the second support plate 35 are connected side by side on the base 33 along a first direction, at least one of the first support plate 34 and the second support plate 35 is configured to be movable relative to the other along the first direction, and the first support plate 34 and the second support plate 35 are used together to support the film strip.

[0092] Before the membrane strip is pulled onto the support platform 3, the relative movement of the first support plate 34 and the second support plate 35 can be controlled according to the desired length of the membrane strip segment, thereby adjusting the dimensions of the support surface of the support platform 3 to match the desired length of the membrane strip segment. This allows the support platform 3 to support membrane strip segments of different lengths to be cut, improving the compatibility of the support platform 3.

[0093] Optionally, at least one of the first support plate 34 and the second support plate 35 is provided with an oblong hole extending along the first direction, and the base 33 is provided with a locking screw hole matching the oblong hole. After adjusting the position of the first support plate 34 or the second support plate 35 in the first direction, the first support plate 34 or the second support plate 35 can be locked onto the base 33 by using a bolt passing through the oblong hole and the locking screw hole.

[0094] In addition, within a certain length range, the support platform 3 is designed to ensure that the junction of the first support plate 34 and the second support plate 35 can provide good support for the membrane strip segment, such as... Figure 3 As shown, the edge of the first bearing plate 34 at the junction is designed to be toothed, and multiple grooves that match the teeth are opened on the edge of the second bearing plate 35 at the junction. The teeth of the first bearing plate 34 extend into the grooves of the second bearing plate 35 one by one. That is, at the junction, there is still a plate between the teeth of the first bearing plate 34 and the grooves of the second bearing plate 35 to support the membrane strip segment, so as to avoid deformation or damage of the membrane strip segment.

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 the protection scope of this application. The scope of protection claimed in this application is defined by the claims, and not by the above descriptions in the embodiments.
