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 of photovoltaic modules, a film strip cutting mechanism is often used to cut film strip segments of predetermined length from the film strip roll. These film strip segments are then used to bond solder strips to the solar cells for stringing. Alternatively, the film strip segments can be further cut into film strips, which are then inserted between adjacent solar cells in the string to prevent microcracks or damage at the lamination points between adjacent solar cells due to excessive rigid extrusion pressure during lamination.

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

[0004] Due to factors such as vibration in the feeding section and traction error in the traction section, the film belt pulled into the pressing and cutting section experiences a positional shift in the second direction (perpendicular to the first direction), ultimately resulting in film belt skew and the inability to obtain a qualified film belt segment.

[0011] The film strip cutting mechanism provided in this application can correct the position of the film strip in the second direction by at least one of the feeding section and the pressing and cutting section, thereby ensuring the position accuracy of the film strip to be cut in the pressing and cutting section, and ultimately ensuring that qualified film strip segments can be obtained.

[0012] In some embodiments, the feeding unit includes a first mounting part, a feeding roller, and a rotary drive module, wherein: the feeding roller is rotatably connected to the first mounting part and is drively connected to the rotary drive module disposed on the first mounting part; the feeding roller is used to mount the film strip roll; and the rotary drive module is configured to drive the feeding roller to rotate so as to drive the film strip roll to rotate synchronously.

[0013] By configuring the feeding unit, the film tape roll can be installed and driven to rotate, thereby achieving automatic release of the film tape.

[0014] In some embodiments, the first mounting portion includes a first mounting frame, a second mounting frame, and a first translation drive module, wherein: the second mounting frame is slidably connected to the first mounting frame and is drively connected to the first translation drive module disposed on the first mounting frame; the feeding roller and the rotation drive module are both disposed on the second mounting frame; the first translation drive module is configured to drive the second mounting frame to slide along a second direction to adjust the position of the film strip roll in the second direction.

[0015] By configuring the first mounting part, the first mounting part can adjust the position of the film strip roll in the second direction, thereby correcting the position of the film strip released from the film strip roll in the second direction.

[0016] In some embodiments, the feeding section further includes at least one guide roller disposed on the first mounting section, the guide roller being used to guide the film strip released from the film strip roll toward the pressing and cutting section.

[0017] By setting guide rollers, the film strip released from the film roll is guided, ensuring that the film strip released from the film roll can smoothly enter the pressing and cutting section.

[0018] In some embodiments, the clamping and cutting portion includes a second mounting portion, a first clamping assembly, and a cutting assembly, wherein: the first clamping assembly and the cutting assembly are disposed on the second mounting portion, and the film strip passes through the first clamping assembly and the cutting assembly in sequence, wherein the first clamping assembly is configured to clamp the film strip from a first side of the cutting assembly, and the cutting assembly is configured to cut the clamped film strip to obtain a film strip segment.

[0019] When the cutting assembly cuts the film strip, the first pressing assembly presses the film strip from the first side of the cutting assembly, thereby enabling the cutting assembly to smoothly cut the film strip, and pressing and holding the new free end of the film strip after cutting within the pressing and cutting part to prevent the film strip from shrinking back.

[0020] In some embodiments, the second mounting portion includes a base, a third mounting bracket, and a second translation drive module, wherein: the third mounting bracket is slidably connected to the base, the second translation drive module is disposed on the base and is drively connected to the third mounting bracket; the first pressing assembly and the cutting assembly are both disposed on the third mounting bracket; the second translation drive module is configured to drive the third mounting bracket to slide relative to the base along a second direction to adjust the position of the film strip pressed by the first pressing assembly in the second direction.

[0021] By configuring the second mounting part, the second mounting part can drive the first pressing component and the cutting component to move along the second direction, thereby adjusting the position of the film strip pressed by the first pressing component in the second direction.

[0022] 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 third mounting bracket; the first lifting drive module is disposed on the third mounting bracket and located above the pressure plate, 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 configured to drive the first pressure plate to lift and lower to press the film strip onto the pressure plate or release the film strip from a first side of the cutting assembly.

[0023] 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.

[0024] In some embodiments, the cutting assembly includes a third translation drive module and a cutter, wherein: the third translation drive module is disposed on a third mounting bracket, and the cutter is connected to a movable part of the third translation drive module; the third translation drive module is configured to drive the cutter to translate along a second direction to cut the film strip located on the translation path of the cutter.

[0025] The third 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 component simpler.

[0026] In some embodiments, the clamping and cutting portion further includes a second clamping assembly disposed on a third mounting bracket, the cutting assembly being located between the first clamping assembly and the second clamping assembly, the second clamping assembly being configured to clamp the film strip to a first end of the support platform from a second side of the cutting assembly, the first end of the support platform being the end of the support platform near the clamping and cutting portion; the cutting assembly being configured to cut the film strip clamped by the first clamping assembly and the second clamping assembly.

[0027] When the cutting assembly cuts the membrane strip, the first clamping assembly and the second clamping assembly clamp the membrane strip from adjacent positions on both sides of the cutting assembly, thereby making the membrane strip fully taut when it is cut to form a straight cut and ultimately ensure that a membrane strip segment with a straight edge is obtained.

[0028] In some embodiments, the clamping and cutting part further includes a fourth translation drive module, and the base is disposed on the movable part of the fourth translation drive module; the fourth translation drive module is configured to drive the base to translate along a first direction to switch the base 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, and when the base is switched to the clearance position, the second clamping component is located on the first side of the support platform.

[0029] When the base is switched to the avoidance position, the base and all its components are moved away from the carrier platform to avoid it, so that the subsequent membrane strip transport mechanism (such as a moving suction cup) can remove the membrane strip from the carrier platform.

[0030] 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.

[0031] In some embodiments, the film tape cutting mechanism further includes a detection unit disposed between the feeding unit and the pressing and cutting unit; the film tape released from the feeding unit passes through the detection unit and enters the pressing and cutting unit; the detection unit is configured to detect the edge of the film tape to determine whether the film tape is skewed; the feeding unit is configured to adjust the position of the film tape roll in the second direction according to the position of the film tape in the second direction; the pressing and cutting unit is configured to adjust the position of the film tape in the second direction according to the position of the film tape in the second direction.

[0032] By setting a detection unit between the feeding unit and the pressing and cutting unit, the position of the film belt to be entered into the pressing and cutting unit in the second direction is detected to determine whether the film belt is deviated, so that the feeding unit and / or the pressing and cutting unit can perform a deviation correction operation on the film belt according to the detection result.

[0033] In some embodiments, the detection unit includes a fourth mounting bracket and an edge detection sensor, wherein: the edge detection sensor is disposed on the fourth mounting bracket; the film strip released from the feeding unit passes through the edge detection sensor and enters the pressing and cutting unit, and the edge detection sensor is used to obtain the edge position of the film strip.

[0034] The edge detection sensor detects the edge of the membrane strip to obtain the position of the membrane strip in the second direction before it enters the pressing and cutting section, thereby determining whether the membrane strip is deviated.

[0035] 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.

[0036] 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.

[0037] In some embodiments, the traction unit includes a fifth translation drive module, a second lifting drive module, and a clamping assembly, wherein: the second lifting drive module is connected to a movable part of the fifth translation drive module, and the clamping assembly is connected to a movable part of the second lifting drive module; the fifth translation drive module is configured to drive the clamping assembly to move along a first direction, and the second lifting drive module is configured to drive the clamping assembly to lift, so that the clamping assembly clamps the free end of the film strip from the pressing and cutting part, and pulls the film strip along the first direction to the support platform.

[0038] By incorporating a fifth translation 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 the second lifting drive module. After the gripping assembly pulls the film strip above the support platform, it descends to a low position under the drive of the second lifting drive module, thereby tensioning the film strip to the second end of the support platform. This further improves the cutting effect of the cutting assembly on the film strip. Attached Figure Description

[0068] 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.

[0069] As described in the background section, existing film strip cutting mechanisms cause the film strip pulled into the pressing and cutting section to shift due to factors such as vibration in the feeding section and traction error in the traction section. This results in the film strip being skewed and unable to obtain qualified film strip segments.

[0070] To address this problem, this application provides a film strip cutting device that can perform position correction of the film strip, thereby ensuring the positional accuracy of the film strip to be cut within the pressing and cutting section, and ultimately ensuring that qualified film strip segments can be obtained.

[0071] like Figure 1 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:

[0072] The feeding section 1 is configured to install the film tape roll and drive the film tape roll to rotate to release the film tape. The clamping and cutting section 2 is located between the feeding section 1 and the support table 3, and the clamping and cutting section 2 is configured to clamp the film tape.

[0073] 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 along a first direction (e.g., the X direction) onto the support table 3.

[0074] The pressing and cutting section 2 is configured to press the film strip and cut the film strip to obtain film strip segments.

[0075] The feeding unit 1 is further configured to drive the film strip roll to translate along the second direction to adjust the position of the film strip roll in the second direction; and / or, the pressing and cutting unit 2 is further configured to drive the pressed film strip to translate along the second direction to adjust the position of the film strip in the second direction. The second direction is, for example, the Y direction perpendicular to the first direction.

[0076] The optional working process of the film strip cutting mechanism in this application embodiment is as follows:

[0077] Initially, the free end of the film strip is pressed within the clamping and cutting section 2. When the film strip is misaligned in the second direction, the feeding section 1 is controlled to drive the film strip roll to translate along the second direction, and / or the clamping and cutting section 2 is controlled to drive the pressed film strip to translate along the second direction, thereby completing the correction of the film strip in the second direction. When the film strip is not misaligned in the second direction, no correction of the film strip is performed.

[0078] 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 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 clamping and cutting unit 2 and enters the support table 3.

[0079] Subsequently, the pressing and cutting part 2 presses the film strip, and the pressing and cutting part 2 cuts the pressed film strip, thereby obtaining the film strip segment located on the support platform 3.

[0080] As can be seen, the film strip cutting mechanism provided in this application can correct the position of the film strip in the second direction by at least one of the feeding part 1 and the pressing and cutting part 2, thereby ensuring the position accuracy of the film strip to be cut in the pressing and cutting part 2, and ultimately ensuring that qualified film strip segments can be obtained.

[0081] like Figures 1 to 2 As shown, optionally, the feeding unit 1 includes a first mounting part, a feeding roller 14, and a rotary drive module 15, wherein: the feeding roller 14 is rotatably connected to the first mounting part and is drively connected to the rotary drive module 15 disposed on the first mounting part; the feeding roller 14 is used to mount the film strip roll; the rotary drive module 15 is configured to drive the feeding roller 14 to rotate, thereby driving the film strip roll to rotate synchronously. The feeding roller 14 may be an air shaft, which can be inserted into the hollow part inside the film strip roll.

[0082] It can be seen that by configuring the feeding unit 1, the feeding unit 1 can install the film tape roll and drive the film tape roll to rotate, thereby realizing the automatic release of the film tape.

[0083] Optionally, the first mounting section includes a first mounting frame 11, a second mounting frame 12, and a first translation drive module 13, wherein the second mounting frame 12 is slidably connected to the first mounting frame 11 and is drively connected to the first translation drive module 13 disposed on the first mounting frame 11. The feeding roller 14 and the rotation drive module 15 are both disposed on the second mounting frame 12.

[0084] The second mounting bracket 12 and the first mounting bracket 11 are slidably connected by at least two first linear guide pairs. The first linear guide pairs extend along the second direction. The second mounting bracket 12 is driven to slide relative to the first mounting bracket 11 along the second direction by the first translation drive module 13. The position of the film strip roll in the second direction can be adjusted, thereby realizing the position correction of the film strip released from the film strip roll in the second direction.

[0085] Figure 2 The first translation drive module 13 in the illustrated embodiment includes a first motor 131, a first lead screw 132, and a first nut 133. The first motor 131 is mounted on a first mounting bracket 11. The first lead screw 132 is rotatably mounted on the first mounting bracket 11. One end of the first lead screw 132 is connected to the first motor 131 via a belt assembly. The first lead screw 132 extends along a second direction. The first nut 133 is fixed to a second mounting bracket 12 and screwed onto the first lead screw 132. The first motor 131 drives the first lead screw 132 to rotate via the belt assembly, thereby causing the first nut 133 to move along the first lead screw 132, and subsequently causing the second mounting bracket 12 to slide relative to the first mounting bracket 11 along the second direction.

[0086] Of course, the first translation drive module 13 can also adopt other existing linear drive modules, such as cylinders, as long as they can drive the second mounting bracket 12 to slide relative to the first mounting bracket 11 in the second direction.

[0087] like Figure 1 As shown, optionally, the feeding unit 1 also includes at least one guide roller 16 disposed on the first mounting unit. The guide roller 16 is used to guide the film strip released from the film roll toward the pressing and cutting unit 2, thereby ensuring that the film strip released from the film roll can smoothly enter the pressing and cutting unit 2.

[0088] like Figures 4 to 6 As shown, optionally, the pressing and cutting part 2 includes a second mounting part, a first pressing assembly 24 and a cutting assembly 25, wherein: the first pressing assembly 24 and the cutting assembly 25 are disposed on the second mounting part, and the film strip passes through the first pressing assembly 24 and the cutting assembly 25 in sequence, wherein the first pressing assembly 24 is configured to press the film strip from the first side of the cutting assembly 25, and the cutting assembly 25 is configured to cut the pressed film strip to obtain a film strip segment.

[0089] When the cutting assembly 25 cuts the film strip, the first pressing assembly 24 presses the film strip from the first side of the cutting assembly 25, so that the cutting assembly 25 can smoothly cut the film strip, and the new free end of the film strip after cutting is pressed and held in the pressing and cutting part 2 to prevent the film strip from shrinking back.

[0090] like Figures 4 to 6As shown, optionally, the second mounting part includes a base 21, a third mounting bracket 22, and a second translation drive module 23, wherein: the third mounting bracket 22 is slidably connected to the base 21, and the second translation drive module 23 is disposed on the base 21 and is drively connected to the third mounting bracket 22. The first pressing assembly 24 and the cutting assembly 25 are both disposed on the third mounting bracket 22, and the second translation drive module 23 is configured to drive the third mounting bracket 22 to slide relative to the base 21 along a second direction to adjust the position of the film strip pressed by the first pressing assembly 24 in the second direction.

[0091] As can be seen, by setting the second mounting part, the second mounting part can drive the first pressing component 24 and the cutting component 25 to move along the second direction, thereby adjusting the position of the film strip pressed by the first pressing component 24 in the second direction.

[0092] like Figure 6 As shown, optionally, the second translation drive module 23 includes a third motor 231, a second lead screw 232, and a second nut 233, wherein: the third motor 231 is mounted on the base 21, the second lead screw 232 is rotatably mounted on the base 21 and is connected to the third motor 231 for transmission, the second lead screw 232 extends along a second direction, and the second nut 233 is fixed to the third mounting bracket 22 and screwed onto the second lead screw 232. The third motor 231 drives the second lead screw 232 to rotate, thereby causing the second nut 233 to move along the second lead screw 232, and further causing the third mounting bracket 22 to slide relative to the base 21 along the second direction.

[0093] Of course, the second translation drive module 23 can also adopt other existing linear drive modules, such as cylinders, as long as they can drive the third mounting bracket 22 to slide relative to the base 21 in the second direction.

[0094] like Figures 4 to 6 As shown, optionally, the first pressing assembly 24 includes a pressure plate 241, a first pressure plate 242, and a first lifting drive module 243, wherein: the pressure plate 241 is disposed on the third mounting bracket 22; the first lifting drive module 243 is disposed on the third mounting bracket 22 and located above the pressure plate 241, the first pressure plate 242 is connected to a movable part of the first lifting drive module 243, and the first pressure plate 242 is located above the pressure plate 241. The film strip passes between the first pressure plate 242 and the pressure plate 241, and the first lifting drive module 243 is configured to drive the first pressure plate 242 to rise and fall, so as to press the film strip onto the pressure plate 241 from the first side of the cutting assembly 25 or release the film strip.

[0095] The first lifting drive module 243 can be any existing linear drive module capable of driving the first pressure plate 242 to lift, such as a cylinder, a motor with a lead screw and nut mechanism, etc.

[0096] Optionally, the cutting assembly 25 includes a third translation drive module 251 and a cutter 252, wherein: the third translation drive module 251 is disposed on the third mounting bracket 22, and the cutter 252 is connected to a movable part of the third translation drive module 251. The third translation drive module 251 is configured to drive the cutter 252 to translate along a second direction to cut the film strip located on the translation path of the cutter 252.

[0097] The third translation drive module 251 drives the cutter 252 to pass through the translation path of the cutter 252 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 does not require the setting of a cutting plate corresponding to the cutter 252, thus making the structure of the cutting assembly 25 simpler.

[0098] Optionally, the clamping and cutting section 2 further includes a second clamping assembly 26 disposed on the third mounting bracket 22. The cutting assembly 25 is located between the first clamping assembly 24 and the second clamping assembly 26. The second clamping assembly 26 is configured to clamp the film strip to the first end of the support platform 3 from the second side of the cutting assembly 25. The first end of the support platform 3 is the end of the support platform 3 closest to the clamping and cutting section 2. The cutting assembly 25 is configured to cut the film strip clamped by the first clamping assembly 24 and the second clamping assembly 26.

[0099] Specifically, when the traction unit 4 pulls the clamped film strip along the first direction, causing the film strip of a predetermined length to pass through the clamping and cutting unit 2 and enter the support table 3, the first clamping assembly 24 clamps the film strip from the first side of the cutting assembly 25, and the second clamping assembly 26 clamps the film strip to the first end of the support table 3 from the second side of the cutting assembly 25. Subsequently, the cutting assembly 25 cuts the clamped film strip between the first clamping assembly 24 and the second clamping assembly 26, thereby obtaining a film strip segment located on the support table 3.

[0100] As the cutting assembly 25 cuts the film strip, the first clamping assembly 24 and the second clamping assembly 26 clamp the film strip from adjacent positions on both sides of the cutting assembly 25, thereby making the film strip fully taut when it is cut, thus forming a straight cut and ultimately ensuring that a film strip segment with a straight edge is obtained.

[0101] Optionally, the second pressing assembly 26 includes a second pressure plate 261 and a third lifting drive module 262, wherein the third lifting drive module 262 is disposed on the third mounting bracket 22, and the second pressure plate 261 is connected to a movable part of the third lifting drive module 262. The third lifting drive module 262 is used to drive the second pressure plate 261 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 25 or release the film strip.

[0102] The third lifting drive module 262 can adopt various existing linear drive modules that can drive the second pressure plate 261 to lift, such as cylinders, motors, and lead screw and nut mechanisms.

[0103] like Figure 6 As shown, optionally, the clamping and cutting section 2 also includes a fourth translation drive module 27, with the base 21 mounted on a movable part of the fourth translation drive module 27. The fourth translation drive module 27 is configured to drive the base 21 to translate along a first direction, thereby switching the base 21 between a working position close to the support platform 3 and a clearance position away from the support platform 3. Specifically, the base 21 is slidably connected to a second linear guide pair arranged along the first direction, which guides the movement of the base 21. When the base 21 is switched to the working position, the second clamping assembly 26 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 261 in the second clamping assembly 26. After the cutting assembly 25 cuts the film strip and obtains the film strip segment, the base 21 can be controlled to move to the avoidance position. The second pressing assembly 26 is located on the first side of the support platform 3. The base 21 and its various components are all away from the support platform 3 to avoid the film strip segment so that the subsequent film strip segment handling mechanism (e.g., a moving suction cup) can take away the film strip segment on the support platform 3.

[0104] The fourth translation drive module 27 can be any existing linear drive module that can drive the base 21 to translate between the working position and the avoidance position, such as a cylinder, a motor and a lead screw and nut mechanism.

[0105] like Figures 4 to 5 As shown, optionally, the third mounting bracket 22 includes a first mounting bracket 221, a second mounting bracket 222, and a fifth lifting drive module 223, wherein:

[0106] The first mounting bracket 221 is slidably connected to the base 21, and the second translation drive module 23 is connected to the first mounting bracket 221 through a transmission.

[0107] The second mounting bracket 222 is slidably and vertically connected to the first mounting bracket 221. The first clamping component 24 and the second clamping component 26 are both mounted on the second mounting bracket 222, and the cutting component 25 is mounted on the first mounting bracket 221.

[0108] The fifth lifting drive module 223 is mounted on the first mounting bracket 221. The fifth lifting drive module 223 is used to drive the second mounting bracket 222 to move up and down between the first high position and the first low position.

[0109] The fifth lifting drive module 223 is configured to drive the second mounting bracket 222 down to a first low position to tension the membrane belt to the first end of the support platform 3; the fifth lifting drive module 223 is also configured to drive the second mounting bracket 222 up to a first high position, so that the new free end of the membrane belt after cutting is higher than the support platform 3. The fifth lifting drive module 223 can adopt various existing linear drive modules, such as cylinders, motors with lead screw and nut mechanisms, etc.

[0110] After the cutting assembly 25 cuts the film strip, the third lifting drive module 262 first drives the second pressure plate 261 to rise, moving the second pressure plate 261 away from the support platform 3. Simultaneously, the traction unit 4 releases the film strip segment, and the fourth translation drive module 27 drives the base 21 away from the support platform 3. The film strip segment is then removed from the support platform 3 using the film strip segment transport mechanism. Afterward, the fourth translation drive module 27 drives the base 21 closer to the support platform 3, and the fifth lifting drive module 223 drives the second mounting bracket 222 to rise to the first high position, making... The new free end of the membrane strip is higher than the support platform 3 so that the traction unit 4 can pull the new free end of the membrane strip. The traction unit 4 pulls the membrane strip into place and attaches it to the support platform 3. At the same time, the fifth lifting drive module 223 drives the second mounting bracket 222 to descend to the first low position to tension the membrane strip to the first end of the support platform 3. Then, the third lifting drive module 262 drives the second pressure plate 261 to descend until the second pressure plate 261 presses the membrane strip tightly onto the first end of the support platform 3. The cutting component 25 then cuts the membrane strip. This cycle is repeated to cut the membrane strip.

[0111] like Figure 3 As shown, optionally, the film strip cutting mechanism in this embodiment further includes a detection unit 5 disposed between the feeding unit 1 and the pressing and cutting unit 2. The film strip released from the feeding unit 1 passes through the detection unit 5 and enters the pressing and cutting unit 2. The detection unit 5 is configured to detect the edge of the film strip to determine whether the film strip is skewed. The feeding unit 1 is configured to adjust the position of the film strip roll in the second direction according to the position of the film strip in the second direction to complete the film strip correction. Similarly, the pressing and cutting unit 2 is configured to adjust the position of the film strip in the second direction according to the position of the film strip in the second direction to complete the film strip correction.

[0112] Optionally, the detection unit 5 includes a seventh mounting bracket 51 and an edge detection sensor, wherein the edge detection sensor is mounted on the seventh mounting bracket 51 via a mounting plate 52. The film strip released from the feeding unit 1 enters the pressing and cutting unit 2 through the edge detection sensor, which is used to obtain the edge position of the film strip.

[0113] Optionally, the support platform 3 is provided with an adsorption hole 31 for adsorbing the film belt, 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.

[0114] 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, ensuring that the subsequent membrane strip segment transport mechanism can smoothly obtain the membrane strip segment 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 unit 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 table surface of the support platform 3.

[0115] like Figure 3 As shown, optionally, the traction unit 4 includes a fifth translation drive module 41, a second lifting drive module 42, and a clamping assembly 43, wherein: the second lifting drive module 42 is connected to the movable part of the fifth translation drive module 41, and the clamping assembly 43 is connected to the movable part of the second lifting drive module 42. The fifth translation drive module 41 is configured to drive the clamping assembly 43 to move along a first direction, and the second lifting drive module 42 is configured to drive the clamping assembly 43 to rise and fall, so that the clamping assembly 43 clamps the free end of the film strip from the pressing and cutting part 2 and pulls the film strip along the first direction onto the support platform 3.

[0116] The fifth translation drive module 41 drives the clamping assembly 43 to move along the first direction, clamping 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. The clamping assembly 43 is connected to the movable part of the second lifting drive module 42. After the clamping assembly 43 pulls the film strip above the support platform 3, it descends to a low position under the drive of the second 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 25 on the film strip. After the cutting assembly 25 cuts the film strip, the clamping assembly 43 rises to a high position under the drive of the second lifting drive module 42, above the support platform 3. Thus, during the next cut, the clamping assembly 43 can pass over the support platform 3 to clamp the free end of the film strip, preventing collision with the support platform 3.

[0117] Optionally, the fifth translation drive module 41 includes a fourth motor 411, a second belt 412, and a fourth mounting bracket 413. The second lifting drive module 42 includes a cylinder 421 and a fifth mounting bracket 422. The fourth 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 (as shown by the lower side belt). The fourth motor 411 drives the second belt 412 to rotate, thereby causing the fourth mounting bracket 413 to slide in the first direction. The fifth mounting bracket 422 is slidably and vertically connected to the fourth mounting bracket 413 and connected to the drive end of the cylinder 421 mounted on the fourth mounting bracket 413. A clamping assembly 43 is mounted on the fifth mounting bracket 422, and the cylinder 421 drives the fifth mounting bracket 422 to slide vertically relative to the fourth mounting bracket 413.

[0118] Of course, the fifth translation drive module 41 and the second 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.

[0119] like Figure 7 As shown, optionally, the clamping assembly 43 includes a sixth mounting frame 431, a support plate 432, a fourth lifting drive module 434, a pressure plate 435, and a plurality of clamps 433, wherein: the support plate 432 is fixedly mounted on the sixth mounting frame 431, and the plurality of clamps 433 are rotatably connected to the sixth mounting frame 431. The fourth lifting drive module 434 is mounted on the sixth mounting frame 431, and the pressure plate 435 is connected to the drive end of the sixth mounting frame 431 and is located above the plurality of clamps 433.

[0120] 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 fourth lifting drive module 434 first drives the pressure plate 435 to descend, and 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 fourth 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.

[0121] The number of clearance slots 32 at the second end of the support platform 3 is the same as the number of clamps 433. By setting clearance slots 32 at the second end of the support platform 3, when the clamping component 43 descends to the low position under the drive of the second lifting drive module 42, the clamps 433 are arranged in the corresponding clearance slots 32 to ensure that the edge of the membrane strip is flush with the edge of the second end of the support platform 3, that is, the free end of the membrane strip is located on the platform surface of the support platform 3, so as to avoid the membrane strip being suspended outside the support platform 3 and causing the membrane strip to bend, etc.

[0122] The foregoing has provided a sufficiently detailed and specific description of this application. 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.
