Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic module production equipment, in particular to a film strip processing mechanism and processing device. BACKGROUND

[0002] A photovoltaic module is usually encapsulated by a back sheet, a lower adhesive film, a cell string group, an upper adhesive film and a glass sheet, wherein there are gaps between adjacent two cell pieces in the cell string group and between adjacent two cell strings, and the light energy irradiated to these gaps is difficult to be directly absorbed or utilized. Figure 7 As shown in the figure, in order to improve the utilization rate of light energy, the industry adopts film strip segments with light reflecting performance corresponding to the inter-piece and inter-string positions on the back sheet 500, i.e. inter-piece film strip segment 600 and inter-string film strip segment 700, to reflect the light energy irradiated to the above-mentioned gap positions to the glass sheet through the above-mentioned film strip segments, and then to the cell pieces through the glass sheet, so as to fully utilize the light energy at the gap.

[0003] When implementing the laying of the film strip segment, the film strip needs to be pressed by the film strip pressing mechanism and cut off to obtain a film strip segment with a predetermined length. In order to implement the cutting of the film strip, the existing processing method is to respectively set a film strip pressing mechanism and a film strip cutting mechanism on the pulling path of the film strip, first press the film strip by the film strip pressing mechanism, and then cut off the film strip by the film strip cutting mechanism.

[0004] The film strip pressing mechanism and the film strip cutting mechanism need to be configured with separate driving members to implement pressing or cutting driving, which is complex in structure and increases the difficulty and cost of equipment manufacturing and maintenance. INVENTION CONTENTS

[0005] In view of the above technical problems, the present application provides a film strip processing mechanism, and the detailed technical solutions are as follows:

[0006] A film strip processing mechanism, comprising a mounting bracket, a driving member, a working block, a pressing rod, a pressing head and a cutter, wherein:

[0007] The driving member is arranged on the mounting bracket;

[0008] At least one of the working block and the pressing rod is connected with the driving end of the driving member, the working block has a horizontal pressure receiving surface and a vertical cutting receiving surface, a first cutting edge is formed between the cutting receiving surface and the pressure receiving surface, the pressing head is arranged on the pressing rod and faces the pressure receiving surface, the first end of the cutter is rotationally connected to the working block, and the second end of the cutter is movably connected to the pressing rod, and the cutter has a second cutting edge matched with the first cutting edge;

[0009] The driving member is used to drive the relative movement of the pressing rod and the working block, so that the pressing rod and the working block move away or close to each other;

[0010] When the pressing rod is away from the working block, gaps are formed between the pressing head and the pressure receiving surface and between the second blade and the first blade for the film strip to pass through; when the pressing rod is close to the working block, the pressing head presses the film strip onto the pressure receiving surface, and the second blade and the first blade are closed to cut the film strip.

[0011] The film strip processing mechanism of the embodiment of the application only needs to be provided with one driving member, which can drive the pressing head to press the film strip onto the pressure receiving surface of the working block and drive the second blade of the cutting knife to close to the first blade of the working block to cut the pressed film strip, thereby obtaining a film strip segment, and the structure is simple and compact, and the difficulty and cost of equipment manufacturing and maintenance are reduced.

[0012] In some embodiments, one of the working block and the pressing rod is connected to the driving end of the driving member, the other of the working block and the pressing rod is connected to the mounting bracket, and the driving member drives one of the working block and the pressing rod to move towards or away from the other of the working block and the pressing rod; or, the working block and the pressing rod are both connected to the driving end of the driving member, and the driving member synchronously drives the working block and the pressing rod to move in opposite directions.

[0013] Two simple driving modes are provided, which can ensure that the driving member can drive the working block and the pressing rod to move relatively to move away from or close to each other.

[0014] In some embodiments, the first end of the cutting knife is rotatably connected to the working block via the rotating shaft; the second end of the cutting knife is provided with a waist-shaped hole, a pin shaft is fixedly installed on the pressing rod, the pin shaft penetrates through the waist-shaped hole and can slide in the waist-shaped hole along the extension direction of the waist-shaped hole, and the second blade is arranged on the second end of the cutting knife.

[0015] In this way, when the driving member drives the pressing rod and the working block to move relatively, the cutting knife can rotate relative to the working block about the rotating shaft, so that the second blade and the first blade of the cutting knife are closed or separated.

[0016] In some embodiments, the film strip processing mechanism further comprises a limiting member and a pressing spring, wherein: the limiting member is installed on the rotating shaft and located outside the cutting knife; the pressing spring is sleeved on the rotating shaft, a first end of the pressing spring abuts against the limiting member, and a second end of the pressing spring abuts against the cutting knife, and the pressing spring is used to press the cutting knife against the cutting surface.

[0017] By arranging the limiting member and the pressing spring, the cutting knife can be continuously pressed against the cutting surface by the pressing spring, the gap between the second blade of the cutting knife and the first blade of the working block is reduced, and the second blade of the cutting knife and the first blade of the working block can be better closed to cut the film strip.

[0018] In some embodiments, a step is further arranged on the bearing surface and protrudes from the bearing surface, the step is located on the side of the rotating shaft away from the second blade, and the step is used to support the first end of the cutter, and the second end of the cutter can be deflected towards the bearing surface under the pressure of the compression spring.

[0019] By arranging the step on the bearing surface and protruding from the bearing surface, the first end of the cutter is supported, so that the second end of the cutter is deflected towards the bearing surface under the pressure of the compression spring, the second end of the cutter is fully attached to the bearing surface, and finally the second blade and the first blade are fully engaged to cut the film strip.

[0020] In some embodiments, the rotating shaft is provided with external threads, and the limiting member has a threaded hole matched with the external threads, and the limiting member is adjustably screwed on the external threads of the rotating shaft through the threaded hole.

[0021] By rotating the limiting member, the pressure of the compression spring can be flexibly adjusted, so that the cutter is attached to the bearing surface with appropriate force. In this way, it can not only ensure that the second blade of the cutter and the first blade of the working block can cut the film strip when they are engaged, but also avoid excessive pressure of the compression spring on the cutter, which may cause excessive friction between the cutter and the bearing surface, resulting in the driving member being unable to smoothly drive the pressure rod and the working block to move relatively.

[0022] In some embodiments, at least one pressure head is installed on the pressure rod along the length direction, and each pressure head is used to press a film strip, and the second blade and the first blade cut the film strips pressed by the pressure heads when they are engaged.

[0023] When there is only one pressure head on the pressure rod, the solder strip processing mechanism can press and cut one film strip; when there are at least two pressure heads on the pressure rod, each pressure head can press one film strip, and the second blade and the first blade can cut all the film strips on the solder strip processing mechanism, and the structure is more simple and compact.

[0024] The application also provides a film strip processing device, comprising a mounting plate and a plurality of film strip processing mechanisms as described above, wherein the mounting plate extends along a first direction, and the plurality of film strip processing mechanisms are arranged on the mounting plate along the first direction; the plurality of film strip processing mechanisms are configured to press and cut a plurality of film strips passing through each film strip processing mechanism along a second direction, and the second direction is perpendicular to the first direction.

[0025] The film strip processing device provided by the application can simultaneously press and cut a plurality of film strips, improve the preparation efficiency of the film strip section, has a simple and compact structure, and reduces the difficulty and cost of equipment manufacturing and maintenance.

[0026] In some embodiments, among the film strip processing mechanisms, the one in the middle is a first film strip processing mechanism, and the rest are second film strip processing mechanisms. The first film strip processing mechanism is provided with two pressing heads, and the second film strip processing mechanisms are provided with one pressing head. The distance between the two pressing heads of the first film strip processing mechanism is smaller than the distance between the rest of the pressing heads.

[0027] Through the above-mentioned arrangement of the film strip processing mechanisms of the film strip processing device in the embodiments of the present application, the film strip processing device in the embodiments of the present application can cooperate with the external film strip feeding device to prepare a plurality of inter-sheet film strip segments required by the backboard, and realize that the distance between two adjacent inter-sheet film strip segments at the middle position is smaller than the distance between adjacent inter-sheet film strip segments at other positions. Finally, when the prepared plurality of inter-sheet film strip segments are laid on the backboard, the through hole at the middle position of the backboard will not be blocked.

[0028] In some embodiments, the film strip processing device further comprises a first driving mechanism and a second driving mechanism. The mounting plate is connected to a moving part of the first driving mechanism, and the first driving mechanism is configured to drive the mounting plate to reciprocate in a first direction. The second driving mechanism is installed on the mounting plate and drivingly connected with the first film strip processing mechanism. The second driving mechanism is configured to drive the first film strip processing mechanism to reciprocate in the first direction.

[0029] Through the first driving mechanism, the mounting plate is driven to reciprocate in the first direction, which can drive the film strip processing mechanisms to synchronously switch between the respective corresponding avoiding positions and working positions. When the film strip processing mechanisms synchronously switch to the avoiding positions, the film strip processing mechanisms can avoid the pulled-out film strip. When the film strip processing mechanisms synchronously switch to the working positions, the pulled-out film strips can enter into the corresponding film strip processing mechanisms to receive the clamping and cutting operations.

[0030] Since the length of the first film strip processing mechanism at the middle position in the first direction is greater than that of the second film strip processing mechanism, through the second driving mechanism, the movement stroke of the first film strip processing mechanism in the first direction is compensated, which ensures that the first film strip processing mechanism can switch between the corresponding avoiding position and working position.

[0042] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0043] As described in the background section, in order to implement the cutting of the film strip, a film strip segment is obtained. The existing processing method is to respectively set a film strip pressing mechanism and a film strip cutting mechanism on the pulling path of the film strip, first press the film strip by the film strip pressing mechanism, and then cut the film strip by the film strip cutting mechanism. The film strip pressing mechanism and the film strip cutting mechanism need to be configured with separate driving members to implement the pressing or cutting driving, which is structurally complex, and increases the difficulty and cost of equipment manufacturing and maintenance.

[0044] In order to solve this problem, the present application provides a film strip processing mechanism, which only needs to be provided with one driver, and can implement the pressing and cutting of the film strip, thereby reducing the difficulty and cost of equipment manufacturing and maintenance.

[0045] As Figures 1 to 4 ​​As shown, the membrane strip processing mechanism in this embodiment includes a mounting bracket 1, a driving component 2, a working block 3, a pressure rod 4, a pressure head 5, and a cutter 6, wherein:

[0046] The drive unit 2 is mounted on the mounting bracket 1.

[0047] At least one of the working block 3 and the pressure rod 4 is connected to the driving end of the driving member 2. The working block 3 has a horizontal bearing surface 7 and a vertical cutting surface 8. A first cutting edge 9 is formed between the cutting surface 7 and the bearing surface 8. The pressure head 5 is disposed on the pressure rod 4 and faces the bearing surface 8. The first end of the cutter 6 is rotatably connected to the working block 3, and the second end of the cutter 6 is movably connected to the pressure rod 4. The cutter 6 has a second cutting edge 10 that matches the first cutting edge 9.

[0048] The driving component 2 is used to drive the pressure rod 4 and the working block 3 to move relative to each other, so that the pressure rod 4 moves away from or closer to the working block 3.

[0049] When the pressure rod 4 is far from the working block 3, gaps are formed between the pressure head 5 and the pressure surface 7, and between the second blade 10 and the first blade 9, to allow the membrane strip to pass through. When the pressure rod 4 and the working block 3 are close together, the pressure head 5 presses the membrane strip tightly onto the pressure surface 7, and the second blade 10 and the first blade 9 engage to cut the membrane strip.

[0050] The membrane strip processing mechanism of this application embodiment only needs to be equipped with one driving member, which can drive the pressure head 5 to press the membrane strip onto the pressure surface 7 of the working block 3, and can also drive the second blade 10 of the cutter 6 to engage with the first blade 9 of the working block 3 to cut the pressed membrane strip and obtain a membrane strip segment. Its structure is simple and compact, reducing the difficulty and cost of equipment manufacturing and maintenance.

[0051] The membrane strip processing mechanism of this application embodiment can be used to prepare membrane strip segments required for backsheet film laying.

[0052] Optional, such as Figure 1 As shown, both the working block 3 and the pressure rod 4 are connected to the driving end of the driving component 2. The driving component 2 synchronously drives the working block 3 and the pressure rod 4 to move in opposite directions, thereby causing the pressure rod 4 to move away from or closer to the working block 3. The driving component 2 can be any existing driving device capable of synchronously driving the working block 3 and the pressure rod 4 to move in opposite directions. For example, the driving component 2 can be a gripper cylinder, with the pressure rod 4 and the working block 3 respectively connected to one of the driving ends of the gripper cylinder. The gripper cylinder synchronously drives the working block 3 and the pressure rod 4 to move in opposite directions. Alternatively, the driving component 2 can include two cylinders that can be driven in opposite directions, with the two cylinders respectively connected to the working block 3 and the pressure rod 4.

[0053] Of course, in other embodiments, one of the pressure rod 4 and the working block 3 can be fixed on the mounting bracket 1, and the other one of the pressure rod 4 and the working block 3 is connected to the driving end of the driving member 2, and the driving member 2 only drives the other one of the pressure rod 4 and the working block 3 to move, so as to realize the relative movement of the pressure rod 4 and the working block 3. The driving member 2 can be, for example, a gas cylinder, a lead screw motor or the like.

[0054] In order to ensure the cutting effect of the film strip, in actual use, the size and installation position of the pressure rod 4 and the cutter 6 can be adjusted, so that in the process of the relative movement of the pressure rod 4 and the working block 3 driven by the driving member 2, the first pressure head 5 first presses the film strip to the upper surface of the pressure surface 7, and then the second blade 10 and the first blade 9 are closed to cut the film strip, so that the film strip is first pressed and then cut, thereby ensuring the cutting effect of the film strip. Of course, the first pressure head 5 can press the film strip to the pressure surface 7 at the same time, and the second blade 10 and the first blade 9 are closed to cut the film strip.

[0055] As shown in Figures 1 to 2 Optionally, the first end of the cutter 6 is rotatably connected to the working block 3 through the rotating shaft 11. The second end of the cutter 6 is provided with a waist-shaped hole 12, and the pin shaft 13 fixedly installed on the pressure rod 4 penetrates through the waist-shaped hole 12 and can slide in the waist-shaped hole 12 along the extension direction of the waist-shaped hole 12, and the second blade 10 is arranged on the second end of the cutter.

[0056] In this way, when the driving member 2 drives the relative movement of the pressure rod 4 and the working block 3, the cutter 6 can rotate relative to the working block 3 around the rotating shaft 11, so that the second blade 10 of the cutter 6 and the first blade 9 of the working block 3 are closed or separated.

[0057] Optionally, the film strip processing mechanism in the embodiment of the application further comprises a limiting member 14 and a pressing spring 15, wherein: the limiting member 14 is installed on the rotating shaft 11 and located outside the cutter 6. The pressing spring 15 is sleeved on the rotating shaft 11, the first end of the pressing spring 15 abuts against the limiting member 14, and the second end of the pressing spring 15 abuts against the cutter 6, and the pressing spring 15 is used to press the cutter 6 against the cutting surface 8.

[0058] By arranging the limiting member 14 and the pressing spring 15, the cutter 6 is continuously pressed against the cutting surface 8 by the pressing spring 15, so as to reduce the gap between the second blade 10 of the cutter 6 and the first blade 9 of the working block 3, and ensure that the second blade 10 of the cutter 6 and the first blade 9 of the working block 3 can be better closed to cut the film strip.

[0059] Optionally, the rotating shaft 11 is provided with external threads, and the limiting member 14 has a threaded hole matched with the external threads, and the limiting member 14 is adjustably screwed on the external threads of the rotating shaft 11 through the threaded hole.

[0060] By rotating the limiting member 14, the flexible adjustment of the pressing force of the compression spring 15 can be realized, so that the cutter 6 is attached to the bearing cutting surface 8 with appropriate force. In this way, while ensuring that the second cutting edge 10 of the cutter 6 is engaged with the first cutting edge 9 of the working block 3 to cut the film strip, the pressure of the compression spring 15 on the cutter 6 is avoided to be too large, which causes the friction between the cutter 6 and the bearing cutting surface 8 to be too large, resulting in the driving member 2 unable to smoothly drive the compression rod 4 and the working block 3 to move relative to each other.

[0061] As shown in Figures 2 to 4 Optionally, the bearing cutting surface 7 is further provided with a step 16 protruding from the bearing cutting surface 7, the step 16 is located on the side of the rotating shaft 11 away from the second cutting edge 10, and the step 16 is used to support the first end of the cutter 6, so that the second end of the cutter 6 can be deflected towards the bearing cutting surface 7 under the pressure of the compression spring 15. In this way, it can be ensured that the second end of the cutter 6 is fully attached to the bearing cutting surface 7, and finally the second cutting edge 10 on the cutter 6 is fully engaged with the first cutting edge 9 on the working block 3 to cut the film strip.

[0062] Optionally, at least one pressure head 5 is installed on the compression rod 4 along the length direction, and each pressure head 5 is used to press a film strip. When the second cutting edge 10 is engaged with the first cutting edge 9, each pressure head 5 cuts the film strip pressed by the pressure head 5. For example, when only one pressure head 5 is provided on the compression rod 4, the film strip processing mechanism can press and cut one film strip. When two pressure heads 5 are provided on the compression rod 4 along the length direction, the film strip processing mechanism can press and cut two film strips. The number of pressure heads 5 provided on the compression rod 4 can be selected as needed, such as one, two, three or more.

[0063] Based on the same application concept, the application also provides a film strip processing device. As shown in Figure 5 The film strip processing device in the embodiment of the application comprises a mounting plate 100 and a plurality of film strip processing mechanisms 200, wherein the film strip processing mechanism 200 is any one of the film strip processing mechanisms described above.

[0064] The mounting plate 100 extends along a first direction (such as the X direction), and the plurality of film strip processing mechanisms 200 are arranged on the mounting plate 100 along the first direction. The plurality of film strip processing mechanisms 200 are configured to press a plurality of film strips 800 passing through each film strip processing mechanism 200 along a second direction (such as the Y direction), and cut the plurality of film strips 800, the second direction being perpendicular to the first direction. For the sake of simplicity, Figure 5 Only one film strip 800 is shown in the figure.

[0065] The membrane strip processing device provided in this application embodiment can simultaneously press and cut several membrane strips through several membrane strip processing mechanisms 200. The number of membrane strip processing mechanisms 200 can be set according to the actual number of membrane strips to be processed simultaneously, thereby improving the preparation efficiency of membrane strip segments. Its structure is simple and compact, reducing the difficulty and cost of equipment manufacturing and maintenance.

[0066] The membrane strip processing apparatus provided in this application embodiment can prepare the membrane strip segments required for the backsheet. Combined with... Figure 7 As shown, the membrane strip processing apparatus of this application embodiment can simultaneously prepare several inter-sheet membrane strip segments 600 required for the backplate 500, and can also simultaneously prepare several inter-string membrane strip segments 700 required for the backplate 500, thereby improving the membrane strip segment preparation efficiency.

[0067] When using the film strip processing device provided in this application embodiment to prepare film strip segments, it needs to cooperate with an external film strip unwinding device and a film pulling device. The film strip unwinding device is used to unwind multiple film strips, and the film pulling device is used to pull the multiple film strips released by the film strip unwinding device out along a second direction for a predetermined length. Then, the film strip processing device provided in this application embodiment is used to press and cut the pulled-out multiple film strips to obtain multiple film strip segments.

[0068] by Figure 7 Taking the backplate 500 shown as an example, 25 inter-sheet film strip segments 600 need to be laid on it. By selecting and setting the number of film strip processing mechanisms 200 in the film strip processing device of this application, it can be realized that the film strip processing device of this application can simultaneously complete the pressing and cutting of the 25 film strips released by the film strip feeding device, thereby obtaining 25 inter-sheet film strip segments 600.

[0069] Similarly, with Figure 7 Taking the backplate 500 shown as an example, seven inter-series membrane strip segments 700 need to be laid on its first half (such as the left half) and second half (such as the right half). This can also be achieved by selecting and setting the number of membrane strip processing mechanisms 200 in the membrane strip processing device of this application. The membrane strip processing device of this application can simultaneously complete the synchronous pressing and cutting of the seven membrane strips released by the membrane strip feeding device, thereby obtaining seven inter-series membrane strip segments 700.

[0070] As those skilled in the art know, when encapsulating the backplate, lower adhesive film, battery string, upper adhesive film, and glass plate, a through hole corresponding to each junction box is provided in the middle of the backplate to allow the leads on the junction box in the middle of the battery string to pass through the backplate. For example, as Figure 7As shown, in order to prevent the inter-sheet film strip segment 600 located at the middle position of the backboard 500 from shielding the through hole on the backboard 500, the current common processing method is to make a corresponding avoidance hole 601 on the inter-sheet film strip segment 600 laid at the middle position of the backboard 500.

[0071] When laying the inter-sheet film strip segment 600 at the middle position, or after laying the inter-sheet film strip segment 600 at the middle position and performing the hole making operation on the inter-sheet film strip segment 600, the workload and equipment cost will undoubtedly increase.

[0072] Therefore, two inter-sheet film strip segments 600 can be laid at the middle position of the backboard 500, and only a gap for the lead wire of the junction box to pass through is required between the two inter-sheet film strip segments 600. In this way, the hole making operation does not need to be performed on the film strip segment.

[0073] Based on the above considerations, among the several film strips discharged by the film strip feeding device, the spacing between the two film strips located in the middle can be configured to be smaller than the spacing between the remaining two adjacent film strips.

[0074] Correspondingly, as shown in Figures 5 to 6 The film strip processing device in the embodiment of the present application, among the film strip processing mechanisms 200 thereof, one film strip processing mechanism located in the middle is a first film strip processing mechanism 200a, and the remaining film strip processing mechanisms are second film strip processing mechanisms 200b. Among them, two pressing heads 5 are arranged on the first film strip processing mechanism 200a, and one pressing head 5 is arranged on the second film strip processing mechanism 200b. The spacing between the two pressing heads 5 on the first film strip processing mechanism 200a is smaller than the spacing between the remaining pressing heads 5.

[0075] Through the above setting of the film strip processing mechanisms 200 of the film strip processing device in the embodiment of the present application, the first film strip processing mechanism 200a can implement synchronous pressing and cutting of the two inter-sheet film strip segments 600 with close spacing to be laid at the middle position of the backboard 500, and the second film strip processing mechanism 200b can implement one-to-one pressing and cutting of the remaining inter-sheet film strip segments 600, which facilitates the spatial layout of each film strip processing mechanism and simplifies the mechanism setting.

[0076] As shown in Figures 5 to 6 Optionally, the film strip processing device in the embodiment of the present application further comprises a first driving mechanism 300 and a second driving mechanism 400. The mounting plate 100 is connected to the movable part of the first driving mechanism 300, and the first driving mechanism 300 is configured to drive the mounting plate 100 to move back and forth in the first direction. The second driving mechanism 400 is installed on the mounting plate 100 and drivingly connected with the first film strip processing mechanism 200a, and the second driving mechanism 400 is configured to drive the first film strip processing mechanism 200a to move back and forth in the first direction.

[0077] like Figure 5 As shown, optionally, the first drive mechanism 300 includes a first mounting bracket 301, a second mounting bracket 302, a first drive module 303, and a second drive module 304. A first end of the mounting plate 100 is slidably connected to the first mounting bracket 301 along a first direction, and a second end of the mounting plate 100 is slidably connected to the second mounting bracket 302 along the first direction. A fixed end of the first drive module 303 is disposed on one of the first end of the mounting plate 100 and the first mounting bracket 301, and a drive end of the first drive module 303 is connected to the other of the first end of the mounting plate 100 and the first mounting bracket 301. A fixed end of the second drive module 304 is disposed on one of the second end of the mounting plate 100 and the second mounting bracket 302, and a drive end of the second drive module 304 is connected to the other of the second end of the mounting plate 100 and the second mounting bracket 302.

[0078] The first drive module 303 and the second drive module 304 cooperate with the drive mounting plate 100 to reciprocate along the first direction. The first drive module 303 and the second drive module 304 can be, for example, existing linear drive components such as cylinders and lead screws.

[0079] Of course, in other embodiments, other drive mechanisms may be used as the first drive mechanism 300, as long as they can drive the mounting plate 100 to move back and forth in the first direction.

[0080] The second drive mechanism 400 can be any existing linear drive component capable of driving the first membrane processing mechanism 200a to reciprocate along the first direction, such as a cylinder, lead screw, etc.

[0081] As mentioned above, during the processing of the film strips, a film pulling device picks up the free ends of several film strips from the film strip feeding device, and then pulls the film strips away from the film strip feeding device in a second direction, so that the several film strips pass through the film strip processing device of this embodiment. When the film pulling device pulls the film strips out to a certain length, the film strip processing device of this embodiment compresses and cuts the several film strips, thereby obtaining several film strip segments between the film pulling device and the film strip processing device.

[0082] The first drive mechanism 300 drives the mounting plate 100 to reciprocate along the first direction, which can drive each membrane strip processing mechanism 200 to switch synchronously between its corresponding avoidance position and working position. When each membrane strip processing mechanism 200 switches to the avoidance position, it can avoid the membrane strips pulled out by the membrane stretching device. When each membrane strip processing mechanism 200 switches to the working position, it can allow each pulled-out membrane strip to enter the corresponding membrane strip processing mechanism 200 for clamping and cutting operations.

[0083] Since the first film strip processing mechanism 200a at the intermediate position needs to implement the pressing and cutting of the two film strips, the length of the first film strip processing mechanism 200a in the first direction is greater than that of the second film strip processing mechanism 200b. Simply relying on the first driving mechanism 300 to drive the mounting plate 100 to move along the first direction to drive the first film strip processing mechanism 200a to move, there may be insufficient movement stroke to make the first film strip processing mechanism 200a switch to the avoiding position or the working position. By setting the second driving mechanism 400, the movement stroke of the first film strip processing mechanism 200a in the first direction can be compensated, so as to ensure that the first film strip processing mechanism 200a can be switched between the corresponding avoiding position and the working position.

[0084] The above has described the present application in sufficient detail with certain particularity. It should be understood by those skilled in the art that the description in the embodiments is only exemplary, and all changes made without departing from the true spirit and scope of the present application should belong to the protection scope of the present application. The scope of protection claimed by the present application is defined by the claims, not by the above description of the embodiments.
