Description

Technical Field

[0001] This application relates to the field of photovoltaic module production, specifically a film strip processing device and film laying equipment. Background Technology

[0002] Photovoltaic modules are typically encapsulated by a backsheet, a lower encapsulating film, cell strings, an upper encapsulating film, and a glass plate. Within these strings, gaps exist between adjacent cells and between adjacent cell strings, making it difficult for light energy reaching these gaps to be directly absorbed or utilized. For example... Figure 11 As shown, in order to improve light energy utilization, the industry uses reflective film strips, namely inter-cell film strips 200 and inter-cell film strips 300, to attach reflective film strips to the backplate 100 at positions corresponding to the inter-cell and inter-cell positions. The light energy irradiated at the gap positions is reflected onto the glass plate through the film strips, and then reflected onto the solar cells through the glass plate, so as to make full use of the light energy at the gap.

[0003] Since there are a large number of inter-sheet film segments 200 or inter-string film segments 300 that need to be laid on the back sheet, an automated film laying device is needed to lay multiple inter-sheet film segments 200 or multiple inter-string film segments 300 at the same time, so as to improve the efficiency of film laying on the back sheet. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a membrane strip processing device, the detailed technical solution of which is as follows:

[0005] A film strip processing device includes a film feeding section, a pressing and cutting section, and a film pulling section arranged sequentially along a first direction, wherein:

[0006] The membrane dispensing section is configured to simultaneously dispense several membrane strips;

[0007] The film-pulling section is configured to move along a first direction to clamp a plurality of film strips from the film-dispensing section and to pull the film strips away from the film-dispensing section along the first direction.

[0008] The pressing and cutting section is configured to press and cut several film strips that are pulled out. The cutting part of the film strip is located on the side of the pressing section away from the film pulling section, so as to obtain several film strip segments with a predetermined length between the pressing and cutting section and the film pulling section.

[0009] The pressing and cutting section and the film stretching section are also configured to lay several film strips to a predetermined position.

[0010] The membrane strip processing device provided in this application has a pressing and cutting part and a membrane pulling part that cooperate with each other to pull out several membrane strips from the membrane feeding part and then cut the membrane strips to obtain several membrane strip segments to be laid; then, the pressing and cutting part and the membrane pulling part lay the several membrane strip segments to the predetermined position, realizing the simultaneous laying of multiple membrane strips, thereby improving the membrane laying efficiency.

[0011] In some embodiments, the pressing and cutting part includes a first driving mechanism, a first mounting plate, and a plurality of pressing and cutting mechanisms, wherein the first mounting plate is mounted on the driving end of the first driving mechanism, and the plurality of pressing and cutting mechanisms are spaced apart on the first mounting plate along a second direction, the number of pressing and cutting mechanisms is less than or equal to the number of film strips released by the film dispensing part, and the first driving mechanism is used to drive the first mounting plate to move along a first direction, and the second direction is perpendicular to the first direction.

[0012] The film-pulling section includes a second drive mechanism, a second mounting plate, and a plurality of film-pulling mechanisms. The second mounting plate is connected to a movable part of the second drive mechanism. The plurality of film-pulling mechanisms are spaced apart on the second mounting plate along a second direction. The number of film-pulling mechanisms is less than or equal to the number of film strips released by the film-releasing section. The second drive mechanism is used to drive the second mounting plate to move along a first direction, so that each film-pulling mechanism clamps at least one film strip from the film-releasing section and pulls the film strip away from the film-releasing section. Each pressing and cutting mechanism is configured to press and cut at least one film strip that has been pulled out.

[0013] The first drive mechanism and the second drive mechanism are also configured to synchronously drive the first mounting plate and the second mounting plate to move along a first direction in order to lay the film strips held by each pressing and cutting mechanism and each film pulling mechanism to a predetermined position.

[0014] By configuring the film-pulling section, it is ensured that the film-pulling section can clamp all the film strips released by the film-laying section and pull the film strips away from the film-laying section; by configuring the pressing and cutting section, it is ensured that the pressing and cutting section can cooperate with the film-pulling section to press and cut all the film strips to obtain several film strip segments of predetermined length, and cooperate with the film-pulling section to lay the film strip segments to predetermined positions.

[0015] In some embodiments, the clamping and cutting part further includes a third driving mechanism. The first mounting plate is mounted on the driving end of the first driving mechanism via the third driving mechanism. The third driving mechanism is used to drive the first mounting plate to reciprocate along the second direction, so as to drive each clamping and cutting mechanism to switch synchronously between the corresponding avoidance position and the working position. When all the clamping and cutting mechanisms are switched to the corresponding avoidance position, each clamping and cutting mechanism is offset from the pulling path of its respective film strip to be cut in the second direction, so that each film pulling mechanism can clamp and pull out the film strip from the film dispensing part. When all the clamping and cutting mechanisms are switched to the corresponding working position, each clamping and cutting mechanism is aligned with the pulling path of its respective film strip to be cut in the second direction, and the film strip enters the corresponding clamping and cutting mechanism.

[0016] By setting a third driving mechanism, the first mounting plate can be driven to reciprocate along the second direction, thereby causing each clamping and cutting mechanism to synchronously switch between its corresponding avoidance position and working position. This ensures that when each clamping and cutting mechanism synchronously switches to the avoidance position, it can avoid the pulling path of its respective film strip to be cut, allowing each film pulling mechanism to clamp and pull out the film strip from the film feeding section. Once the film strip is pulled out to its proper position, each clamping and cutting mechanism synchronously switches to the working position, allowing each film strip to enter its corresponding clamping and cutting mechanism, enabling the clamping and cutting mechanism to perform clamping and cutting of the film strip.

[0017] In some embodiments, the first driving mechanism includes a first driving module, a second driving module, a first mounting bracket, and a second mounting bracket; the third driving mechanism includes a third driving module and / or a fourth driving module, wherein: the first driving module and the second driving module are spaced apart along a second direction; the first mounting bracket is connected to the driving end of the first driving module, the second mounting bracket is connected to the driving end of the second driving module, and the first driving module and the second driving module are configured to synchronously drive the first mounting bracket and the second mounting bracket to translate along a first direction; the first end of the first mounting plate is slidably connected to the first mounting bracket along the second direction, and the second end of the first mounting plate is slidably connected along the second direction. The first mounting plate is slidably connected to the second mounting bracket; the fixed end of the third drive module is disposed on one of the first end of the first mounting plate and the first mounting bracket, and the drive end of the third drive module is connected to the other of the first end of the first mounting plate and the first mounting bracket; the fixed end of the fourth drive module is disposed on one of the second end of the first mounting plate and the second mounting bracket, and the drive end of the fourth drive module is connected to the other of the second end of the first mounting plate and the second mounting bracket; the third drive module and the fourth drive module are used to drive the first mounting plate to reciprocate along the second direction individually or in combination, so as to drive each clamping and cutting mechanism to switch synchronously to the corresponding avoidance position or working position.

[0018] By configuring the first drive mechanism to include a first drive module, a second drive module, a first mounting bracket, and a second mounting bracket, the first drive module and the second drive module can synchronously drive the first mounting plate to translate along the first direction from both ends via the first mounting bracket and the second mounting bracket, thereby improving the driving smoothness of the first mounting plate and preventing the first mounting plate from tilting or jamming.

[0019] By configuring the third drive mechanism to include a third drive module and a fourth drive module, it can be ensured that the third drive mechanism has a sufficiently large driving force to cooperate in driving the first mounting plate to reciprocate along the second direction, thereby driving each clamping and cutting mechanism to switch to the corresponding avoidance position or working position synchronously.

[0020] In some embodiments, the second driving mechanism includes a fifth driving module and a sixth driving module, wherein: the fifth driving module and the sixth driving module are spaced apart along a second direction; a first end of the second mounting plate is connected to the driving end of the fifth driving module, a second end of the second mounting plate is connected to the driving end of the sixth driving module, and the fifth driving module and the sixth driving module are configured to synchronously drive the second mounting plate to move along a first direction.

[0021] By configuring the second drive mechanism to include a fifth drive module and a sixth drive module, the fifth drive module and the sixth drive module can synchronously drive the second mounting plate to translate along the first direction from both ends, thereby improving the driving smoothness of the second mounting plate and preventing the second mounting plate from tilting or jamming.

[0022] In some embodiments, the pressing and cutting mechanism includes a first mounting bracket, a first driving member, a working block, a pressure rod, a first pressure head, and a cutter, wherein: the first mounting bracket is connected to a first mounting plate; the first driving member is disposed on the first mounting bracket; at least one of the working block and the pressure rod is connected to the driving end of the first driving member, the working block has a horizontal pressure-bearing surface and a vertical cutting surface facing the film-laying portion, and a first cutting edge is formed between the cutting surface and the pressure-bearing surface; the first pressure head is disposed on the pressure rod and faces the pressure-bearing surface, a first end of the cutter is rotatably connected to the working block, a second end of the cutter is movably connected to the pressure rod, and the cutter has a second cutting edge that matches the first cutting edge; the first driving member is used to drive the pressure rod and the working block to move relative to each other, so that the pressure rod moves away from or towards the working block; when the pressure rod and the working block move away from each other, gaps are formed between the first pressure head and the pressure-bearing surface and between the second cutting edge and the first cutting edge for the film strip to pass through; when the pressure rod and the working block move towards each other, the first pressure head presses the film strip against the pressure-bearing surface, and the second cutting edge engages with the first cutting edge to cut the film strip.

[0023] By configuring the clamping and cutting mechanism, only one driving component is needed, enabling it to both clamp and cut the film strip, thus reducing the cost and structural complexity of the mechanism. Furthermore, since the cutting surface of the working block faces the film-laying section, the cutting portion of the film strip is located on the side of the clamping section away from the film-laying section. Therefore, after the film strip is cut, the cut end of the resulting film strip segment is clamped and held on the clamping and cutting mechanism.

[0024] In some embodiments, at least one first pressure head is installed at intervals along the length direction on the pressure bar, each first pressure head is used to press a membrane strip, and the membrane strip pressed by each first pressure head is cut off when the second blade is engaged with the first blade.

[0025] When there is only one first pressure head on the pressure bar, the clamping and cutting mechanism can clamp and cut a single membrane strip; when there are at least two first pressure heads on the pressure bar, each first pressure head can clamp a single membrane strip, while the second and first blades can cut all membrane strips on a clamping and cutting mechanism, resulting in a simpler and more compact structure.

[0026] In some embodiments, the first end of the cutter is rotatably connected to the work block via a pivot; the second end of the cutter is provided with a waist-shaped hole, and the second end of the cutter is movably connected to the pressure rod via a pin passing through the waist-shaped hole, the pin being able to slide within the waist-shaped hole along the length direction of the waist-shaped hole.

[0027] With this configuration, when the first driving member drives the pressure rod and the working block to move relative to each other, the cutter can rotate around the pivot relative to the working block, so that the second cutting edge of the cutter is engaged or separated from the first cutting edge.

[0028] In some embodiments, the film stretching mechanism includes a second mounting bracket, a second driving member, a pressure plate, and a second pressure head, wherein: the second mounting bracket is connected to the second mounting plate; the second driving member is disposed on the second mounting bracket, and at least one of the pressure plate and the second pressure head is throttle-connected to the second driving member, and the second driving member is used to drive the second pressure head and the pressure plate to move closer or further away from each other to press or release the film strip.

[0029] A simple membrane stretching mechanism is provided, which drives a second pressure head and a pressure plate to move closer or further apart through a second driving member, thereby enabling rapid pressing and releasing of the membrane strip passing between the second pressure head and the pressure plate.

[0030] In some embodiments, the spacing between the two middle membrane strips released by the membrane release section is smaller than the spacing between the other two adjacent membrane strips;

[0031] One of the film-pulling mechanisms in the middle of the film-pulling section is configured to simultaneously pick up the two middle film strips from the film-laying section, and the remaining film-pulling mechanisms are each configured to pick up one film strip from the film-laying section; or, each film-pulling mechanism in the film-pulling section is configured to pick up one film strip from the film-laying section.

[0032] The middle pressing and cutting mechanism on the pressing and cutting section is configured to simultaneously press and cut the two middle membrane strips; the remaining pressing and cutting mechanisms are each configured to press and cut one membrane strip; or, each pressing and cutting mechanism on the pressing and cutting section is configured to press and cut one membrane strip.

[0033] By setting the spacing of the film strips released by the film-releasing section and setting the structure of the film-pulling section and the pressing and cutting section accordingly, the film strip processing device of this application can lay two film strip segments at a small spacing to the middle position of the back sheet, thereby forming a space between the two film strip segments with a small spacing for the lead wire at the middle position of the photovoltaic module to pass through.

[0034] In some embodiments, the pressing and cutting part further includes a translational drive member disposed on the first mounting plate. The translational drive member is driven to connect with the pressing and cutting mechanism for pressing and cutting the two intermediate film strips. The translational drive member is used to drive the pressing and cutting mechanism to move along the second direction. The remaining pressing and cutting mechanisms are fixedly mounted on the first mounting plate.

[0035] Because the clamping and cutting mechanism used to clamp and cut the two intermediate membrane strips needs to perform both clamping and cutting, its length along the second direction is greater than that of other clamping and cutting mechanisms. By providing a translational drive, compensation can be made for the travel distance of the clamping and cutting mechanism in the second direction, ensuring that the clamping and cutting mechanism can switch between the corresponding avoidance position and the working position.

[0036] In some embodiments, the film feeding section includes a film supply mechanism and a film dispensing mechanism, wherein: the film supply mechanism includes a plurality of feeding rollers, which are used to mount film strip rolls and drive the film strip rolls to rotate to release film strips; the film dispensing mechanism includes a plurality of film feeding heads spaced apart along a second direction, each film feeding head corresponding to a feeding roller, and the film feeding head is configured to receive film strips released from the film strip rolls on the corresponding feeding rollers, and to guide the free end of the film strip to a pickup position and then press the film strip; the film pulling section clamps the free end of the film strip from the pickup position; the film pulling section is also configured to move synchronously with the pressing and cutting section to lay a plurality of film strip segments to a predetermined position; the second direction is perpendicular to the first direction.

[0037] By configuring the film feeding section, it is possible to simultaneously feed out multiple film strips, and to guide and position the free ends of these film strips at the pickup position. This allows the film pulling section to pick up the free ends of multiple film strips from the pickup position each time. Since the film pulling section can move synchronously with the pressing and cutting section, it can automatically transport and lay multiple film strip segments to predetermined positions, further improving the automation level of the film laying process of this application.

[0038] This application also provides a film-laying device, which includes a support mechanism and a film strip processing device as described in any of the above claims, wherein: the film strip processing device is located above the support mechanism; the support mechanism is used to support the backsheet of the photovoltaic module; the film strip processing device and the support mechanism are configured to be movable relative to each other; the pressing and cutting part and the film-pulling part of the film strip processing device are configured to lay a plurality of film strip segments onto the backsheet.

[0039] With the support mechanism and membrane strip processing device, the film laying equipment provided in this application realizes the automatic laying of several membrane strips onto the back plate, thereby improving the film laying efficiency. Attached Figure Description

[0062] 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.

[0063] As described in the background section, since there are a large number of inter-sheet or inter-string membrane segments to be laid on the backsheet, an automated membrane laying device is needed to lay multiple inter-sheet or inter-string membrane segments simultaneously to improve the efficiency of membrane laying on the backsheet.

[0064] Therefore, this application provides a membrane strip processing device that can simultaneously lay several membrane strip segments onto a backing plate, thereby improving the efficiency of backing plate laying.

[0065] like Figure 1 As shown, the film strip processing device in this embodiment includes a film feeding section 1, a pressing and cutting section 2, and a film pulling section 3 arranged sequentially along a first direction (e.g., the X direction), wherein:

[0066] The membrane dispensing unit 1 is configured to simultaneously dispense several membrane strips. Several membrane strips refer to two or more membrane strips. For example, two, three, four, five, or more membrane strips.

[0067] The film-pulling section 3 is configured to move along a first direction to clamp a plurality of film strips from the film-dispensing section 1 and to pull the film strips away from the film-dispensing section 1 along the first direction.

[0068] The pressing and cutting part 2 is configured to press and cut several film strips that are pulled out. The cutting part of the film strip is located on the side of the pressing part 2 away from the film pulling part 3, so as to obtain several film strip segments with predetermined lengths between the pressing and cutting part 2 and the film pulling part 3.

[0069] The pressing and cutting section 2 and the film stretching section 3 are also configured to lay several film strips to a predetermined position.

[0070] The optional operating process of the membrane strip processing device in this embodiment is as follows:

[0071] First, several membrane strips are released from the membrane release section, with the free ends of the membrane strips all facing the pressing and cutting section 2.

[0072] Subsequently, the film-stretching section 3 moves toward the film-stretching section 1 along the first direction and clamps the free ends of several film strips. Then, the film-stretching section 3 moves away from the film-releasing section 1 along the first direction.

[0073] After the film-pulling part 3 moves into place, the pressing and cutting part 2 presses and cuts the several film strips that have been pulled out, thereby obtaining several film strip segments with a predetermined length. Since the cut part of the film strip is located on the side of the pressing part 2 away from the film-pulling part 3, the cut ends of the several film strip segments obtained after cutting are clamped and held in the pressing and cutting part 2, while the other ends of the several film strip segments are clamped by the film-pulling part 3.

[0074] Finally, the pressing and cutting part 2 and the film pulling part 3 lay several film strips at predetermined positions, for example, laying several film strips on the back plate.

[0075] As can be seen, the pressing and cutting section 2 and the film pulling section 3 can cooperate with each other to pull out several film strips from the film feeding section 1 and then cut the film strips, thereby obtaining several film strip segments to be laid. Subsequently, the pressing and cutting section 2 and the film pulling section 3 lay the several film strip segments to the predetermined positions, thereby improving the film laying efficiency. The film strip processing device of this application embodiment can perform film laying operations on the back plate.

[0076] Combination Figure 11 As shown, the membrane strip processing device of this application embodiment can be used to simultaneously lay a number of inter-sheet membrane strip segments 200 onto the back plate 100, or to simultaneously lay a number of inter-string membrane strip segments 300 onto the back plate 100, thereby improving the membrane laying efficiency of the back plate.

[0077] Figure 11 The backplate 100 shown in the diagram requires the laying of 25 inter-sheet film strips 200. Optionally, when the film strip processing device of this embodiment is used to lay the inter-sheet film strips 200, the film-laying section 1 can be configured to simultaneously lay out 25 film strips. Correspondingly, the pressing and cutting section 2 and the film-pulling section 3 are configured to cooperate in pulling out the 25 film strips from the film-laying section 1 and then cutting the film strips, thereby obtaining 25 inter-sheet film strips 200 to be laid. Subsequently, the pressing and cutting section 2 and the film-pulling section 3 lay the 25 inter-sheet film strips 200 onto the backplate 100 at once, thereby maximizing the film laying efficiency. Of course, the film-laying section 1 can also lay out only 2, 3, 4, 5, or other numbers of film strips less than 25. In this case, this application requires laying the inter-sheet film strips 200 onto the backplate 100 in multiple stages.

[0078] Similarly, Figure 11 The backplate 100 shown in the diagram has seven inter-layer membrane strips 300 laid on its first half (e.g., the left half) and second half (e.g., the right half). Optionally, when the membrane strip processing device of this embodiment is used to lay the inter-layer membrane strips 300, the film-laying part 1 can be configured to simultaneously release seven membrane strips. Correspondingly, the pressing and cutting part 2 and the film-pulling part 3 are configured to cooperate in pulling out the seven membrane strips from the film-laying part 1 and then cutting the membrane strips, thereby obtaining seven inter-layer membrane strips 300 to be laid. Subsequently, the pressing and cutting part 2 and the film-pulling part 3 lay the seven inter-layer membrane strips 300 onto the first half or the second half of the backplate 100 in one go, thereby maximizing the membrane laying efficiency. Of course, the membrane placement section 1 may also place only 2, 3, 4, 5 or other numbers of membrane strips less than 7. In this case, the inter-membrane strip segments 300 need to be laid onto the first or second half of the back plate 100 in multiple stages.

[0079] like Figures 2 to 3As shown, optionally, the pressing and cutting section 2 includes a first driving mechanism 21, a first mounting plate 22, and a plurality of pressing and cutting mechanisms 23. The first mounting plate 22 is mounted on the driving end of the first driving mechanism 21. The plurality of pressing and cutting mechanisms 23 are spaced apart on the first mounting plate 22 along a second direction (e.g., the Y direction). The number of pressing and cutting mechanisms 23 is less than or equal to the number of film strips released by the film dispensing section 1. The first driving mechanism 21 drives the first mounting plate 22 to move along a first direction, and the second direction is perpendicular to the first direction. When the number of pressing and cutting mechanisms 23 is equal to the number of film strips released by the film dispensing section 1, the pressing and cutting mechanisms 23 can perform pressing and cutting on the film strips one-to-one. When the number of pressing and cutting mechanisms 23 is less than the number of film strips released by the film dispensing section 1, one or more of the pressing and cutting mechanisms 23 need to press and cut at least two film strips.

[0080] The film-pulling section 3 includes a second drive mechanism 31, a second mounting plate 32, and a plurality of film-pulling mechanisms 33. The second mounting plate 32 is connected to a movable part of the second drive mechanism 31. The plurality of film-pulling mechanisms 33 are spaced apart on the second mounting plate 32 along a second direction (e.g., the Y direction). The number of film-pulling mechanisms 3 is less than or equal to the number of film strips released by the film-releasing section 1. The second drive mechanism 31 drives the second mounting plate 32 to move along a first direction, so that each film-pulling mechanism 33 picks up at least one film strip from the film-releasing section 1 and pulls the film strip away from the film-releasing section 1. Each pressing and cutting mechanism 23 is configured to press and cut at least one pulled film strip. Similarly, when the number of film-pulling mechanisms 33 is equal to the number of film strips released by the film-releasing section 1, the film-pulling mechanisms 33 can perform the picking and pulling of the film strips one by one. When the number of film-pulling mechanisms 33 is less than the number of film strips released by the film-releasing section 1, one or more of the film-pulling mechanisms 33 need to pick up and pull at least two film strips.

[0081] The first drive mechanism 21 and the second drive mechanism 31 are also configured to synchronously drive the first mounting plate 22 and the second mounting plate 32 to move along a first direction in order to lay the film strips held by the respective pressing and cutting mechanisms 23 and the respective film pulling mechanisms 33 to a predetermined position.

[0082] The optional working process of the clamping and cutting part 2 and the film pulling part 3 is as follows:

[0083] The second drive mechanism 31 drives the second mounting plate 32 to move toward the film-pulling section 3 in the first direction, so that each film-pulling mechanism 33 clamps at least one corresponding film strip from the film-dispensing section 1. Subsequently, the second drive mechanism 31 drives the second mounting plate 32 to move away from the film-pulling section 3 in the first direction, so that each film-pulling mechanism 33 synchronously pulls the corresponding film strip away from the film-dispensing section 1.

[0084] After each membrane pulling mechanism 33 pulls the corresponding membrane strip into place, each pressing and cutting mechanism 23 simultaneously presses and cuts at least one of the pulled-out membrane strips, thereby obtaining several membrane strip segments with predetermined lengths.

[0085] Finally, the first drive mechanism 21 and the second drive mechanism 31 synchronously drive the first mounting plate 22 and the second mounting plate 32 to move toward the predetermined position along the first direction, thereby driving each pressing and cutting mechanism 23 and each film pulling mechanism 33 to lay several film strips to the predetermined position.

[0086] like Figure 2 As shown, optionally, the clamping and cutting part 2 also includes a third driving mechanism 24. The first mounting plate 22 is mounted on the driving end of the first driving mechanism 21 through the third driving mechanism 24. The third driving mechanism 24 is used to drive the first mounting plate 22 to reciprocate along a second direction (such as the Y direction) so as to drive each clamping and cutting mechanism 23 to switch synchronously between the corresponding avoidance position and working position.

[0087] When all the clamping and cutting mechanisms 23 are switched to their corresponding avoidance positions, each clamping and cutting mechanism 23 is staggered from the pulling path of its respective film strip to be cut in the second direction. Thus, when the second drive mechanism 31 drives the second mounting plate 32 to move into position along the first direction toward the film pulling section 3, each film pulling mechanism 33 can clamp and pull out the corresponding film strip from the film dispensing section 1. Alternatively, each film pulling mechanism 33 can pass through the gap between the staggered clamping and cutting mechanisms 23 to clamp the free end of the corresponding film strip, or the film dispensing section 1 can push the free end of the film strip toward each film pulling mechanism 33 through the gap between the staggered clamping and cutting mechanisms 23, so that each film pulling mechanism 33 clamps the free end of the corresponding film strip.

[0088] After each clamping and cutting mechanism 23 pulls the corresponding film strip into position, all clamping and cutting mechanisms 23 switch to their corresponding working positions, thereby aligning each clamping and cutting mechanism 23 with the pulling path of its respective film strip to be cut in the second direction, and each film strip enters the corresponding clamping and cutting mechanism 23. In this way, the clamping and cutting mechanism can clamp and cut the corresponding film strip.

[0089] like Figure 2 As shown, optionally, the first drive mechanism 21 includes a first drive module 211, a second drive module 212, a first mounting bracket 213, and a second mounting bracket 214; the third drive mechanism 24 includes a third drive module 241 and a fourth drive module 242, wherein the first drive module 211 and the second drive module 212 are spaced apart along a second direction (e.g., the Y direction). The first mounting bracket 213 is connected to the drive end of the first drive module 211, and the second mounting bracket 214 is connected to the drive end of the second drive module 212.

[0090] The first drive module 211 and the second drive module 212 are configured to synchronously drive the first mounting bracket 213 and the second mounting bracket 214 to translate along a first direction (such as the X direction).

[0091] The first end of the first mounting plate 22 is slidably connected to the first mounting bracket 213 along the second direction, and the second end of the first mounting plate 22 is slidably connected to the second mounting bracket 214 along the second direction. The fixed end of the third drive module 241 is disposed on one of the first end of the first mounting plate 22 and the first mounting bracket 213, and the drive end of the third drive module 241 is connected to the other of the first end of the first mounting plate 22 and the first mounting bracket 213. The fixed end of the fourth drive module 242 is disposed on one of the second end of the first mounting plate 22 and the second mounting bracket 214, and the drive end of the fourth drive module 242 is connected to the other of the second end of the first mounting plate 22 and the second mounting bracket 214.

[0092] The third and fourth drive modules are used to drive the first mounting plate 22 to reciprocate along the second direction, so as to drive each clamping and cutting mechanism 23 to switch to the corresponding avoidance position or working position simultaneously.

[0093] By configuring the first drive mechanism 21 to include a first drive module 211, a second drive module 212, a first mounting bracket 213, and a second mounting bracket 214, the first drive module 211 and the second drive module 212 can synchronously drive the first mounting plate 22 to translate along the first direction from both ends via the first mounting bracket 213 and the second mounting bracket 214. This improves the smoothness of driving the first mounting plate 22 and prevents the first mounting plate 22 from tilting or jamming during translation. The first drive module 211 and the second drive module 212 can be any existing linear drive module capable of driving the first mounting plate 22 to move along the first direction, such as a synchronous belt drive module or a lead screw drive module.

[0094] By configuring the third drive mechanism 24 to include a third drive module 241 and a fourth drive module 242, and having the third drive module 241 and the fourth drive module 242 work together to drive the first mounting plate 22 to reciprocate along the second direction, it can be ensured that the third drive mechanism 24 has a sufficiently large driving force to ensure that the first mounting plate 22 can drive each clamping and cutting mechanism 23 to switch synchronously to the corresponding avoidance position or working position.

[0095] The third drive module 241 and the fourth drive module 242 can be, for example, various existing linear drive components such as cylinders and lead screws that can drive the first mounting plate 22 to reciprocate along the second direction.

[0096] Optionally, when both the third drive module 241 and the fourth drive module 242 are cylinders, the telescopic rods of the two cylinders are installed in opposite directions. That is, when the telescopic rod of the third drive module 241 extends to push the first mounting plate 22 toward the second mounting bracket 214 in the second direction, the telescopic rod of the fourth drive module 242 retracts, thereby pulling the first mounting plate 22 toward the second mounting bracket 214 in the second direction. In other words, the third drive module 241 and the fourth drive module 242 cooperate to drive the first mounting plate 22 to move toward the second mounting bracket 214 in the second direction. Similarly, when the telescopic rod of the fourth drive module 242 extends to push the first mounting plate 22 toward the first mounting bracket 213 in the second direction, the telescopic rod of the third drive module 241 retracts, thereby pulling the first mounting plate 22 toward the first mounting bracket 213 in the second direction. That is, the third drive module 241 and the fourth drive module 242 cooperate to drive the first mounting plate 22 to move toward the first mounting bracket 213 in the second direction.

[0097] Of course, in order to reduce the driving cost, the third driving mechanism 24 may only include the third driving module 241 or only the fourth driving module 242, and the first mounting plate 22 may be driven to reciprocate along the second direction independently by the third driving module 241 or the fourth driving module 242.

[0098] like Figure 2 As shown, optionally, the second drive mechanism 31 includes a fifth drive module 311 and a sixth drive module 312, wherein the fifth drive module 311 and the sixth drive module 312 are spaced apart along a second direction (such as the Y direction). A first end of the second mounting plate 32 is connected to the drive end of the fifth drive module 311, and a second end of the second mounting plate 32 is connected to the drive end of the sixth drive module 312. The fifth drive module 311 and the sixth drive module 312 are configured to synchronously drive the second mounting plate 32 to move along the first direction.

[0099] By configuring the second drive mechanism 31 to include a fifth drive module 311 and a sixth drive module 312, the fifth drive module 311 and the sixth drive module 312 can synchronously drive the second mounting plate 32 to translate along the first direction from both ends, thereby improving the driving smoothness of the second mounting plate 32 and preventing the second mounting plate 32 from tilting or jamming during translation. The fifth drive module 311 and the sixth drive module 312 can be any existing linear drive module capable of driving the second mounting plate 32 to move along the first direction, such as a synchronous belt drive module, a lead screw drive module, etc.

[0100] like Figures 4 to 6As shown, optionally, the clamping and cutting mechanism 23 includes a first mounting bracket 231, a first driving member 232, a working block 233, a pressure rod 234, a first pressure head 235, and a cutter 236, wherein: the first mounting bracket 231 is connected to the first mounting plate 22. The first driving member 232 is disposed on the first mounting bracket 231. At least one of the working block 233 and the pressure rod 234 is connected to the driving end of the first driving member 232. The working block 233 has a horizontal pressure-bearing surface 237 and a vertical cutting surface 238 facing the film-laying part 1, and a first cutting edge 239 is formed between the cutting surface 238 and the pressure-bearing surface 237. The first pressure head 235 is disposed on the pressure rod 234 and faces the pressure-bearing surface 237. The first end of the cutter 236 is rotatably connected to the working block 233, and the second end of the cutter 236 is movably connected to the pressure rod 234. The cutter 236 has a second cutting edge 2310 that matches the first cutting edge 239.

[0101] The first driving member 232 drives the pressure rod 234 and the working block 233 to move relative to each other, causing the pressure rod 234 to move away from or towards the working block 233. When the pressure rod 234 and the working block 233 move away from each other, gaps are formed between the first pressure head 235 and the pressure bearing surface 237, and between the second cutting edge 2310 and the first cutting edge 239, for the membrane strip to pass through. When the pressure rod 234 and the working block 233 move towards each other, the first pressure head 235 presses the membrane strip against the pressure bearing surface 237, and the second cutting edge 2310 engages with the first cutting edge 239 to cut the membrane strip.

[0102] It is evident that by configuring the clamping and cutting mechanism 23, only the first driving member 232 is required. This allows the clamping and cutting mechanism 23 to both clamp the film strip and cut it, thereby reducing the cost and structural complexity of the clamping and cutting mechanism 23. Furthermore, since the cutting surface 238 of the working block 233 faces the film placement part 1, after the second blade 2310 and the first blade 239 engage to cut the film strip clamped by the first pressure head 235 and the pressure surface 237 to obtain a film strip segment, the cut end of the film strip segment is held and pressed between the first pressure head 235 and the pressure surface 237.

[0103] The first driving element 232 can be any existing driver capable of driving the pressure rod 234 and the working block 233 to move relative to each other. For example Figure 6 In the embodiment shown, the first driving component 232 is a gripper cylinder, and the pressure rod 234 and the working block 233 are respectively connected to one driving end of the gripper cylinder. The gripper cylinder drives the pressure rod 234 and the working block 233 to move towards the middle or separate to both sides synchronously.

[0104] In other embodiments, one of the pressure rod 234 and the working block 233 may be fixed to the first mounting bracket 231, while the other of the pressure rod 234 and the working block 233 may be connected to the driving end of the first driving member 232. The first driving member 232 may only drive the other of the pressure rod 234 and the working block 233 to move, thereby realizing relative movement between the pressure rod 234 and the working block 233. The first driving member 232 may be, for example, a linear drive such as a cylinder or a lead screw motor.

[0105] To ensure the cutting effect of the membrane strip, in actual use, the size and installation position of the pressure rod 234 and the cutter 236 can be adjusted so that during the relative movement and close movement of the pressure rod 234 and the working block 233 driven by the first driving member 232, the first pressure head 235 first presses the membrane strip to the pressure surface 237, and then the second blade 2310 and the first blade 239 engage to cut the membrane strip, so that the membrane strip is first pressed and then cut, thereby ensuring the cutting effect of the membrane strip.

[0106] As mentioned in the previous embodiments, the clamping and cutting mechanism 23 can clamp and cut at least one film strip. Correspondingly, optionally, such as Figures 7 to 8 As shown, at least one first pressure head 235 is installed at intervals along the length direction (i.e., the second direction) on the pressure rod 234. Each first pressure head 235 is used to press one film strip. When the second blade 2310 and the first blade 239 are engaged, the film strip pressed by each first pressure head 235 is cut. For example, when only one first pressure head 235 is provided on the pressure rod 234, the pressing and cutting mechanism 23 can press and cut one film strip. When two first pressure heads 235 are provided along the length direction on the pressure rod 234, the pressing and cutting mechanism 23 can press and cut two film strips.

[0107] like Figure 6 As shown, optionally, the first end of the cutter 236 is rotatably connected to the working block 233 via a pivot 2311. The second end of the cutter 236 is provided with a waist-shaped hole 2312, and the second end of the cutter 236 is movably connected to the pressure rod 234 via a pin 2313 passing through the waist-shaped hole 2312. The pin 2313 can slide within the waist-shaped hole 2312 along its length.

[0108] With this configuration, when the first driving member 232 drives the pressure rod 234 and the working block 233 to move relative to each other, the cutter 236 can rotate around the rotating shaft 2311 relative to the working block 233, so that the second cutting edge 2310 of the cutter 236 is engaged or separated from the first cutting edge 239.

[0109] like Figure 4 and Figure 9As shown, optionally, the film stretching mechanism 33 includes a second mounting bracket 331, a second driving member 332, a pressure plate 333, and a second pressure head 334, wherein: the second mounting bracket 331 is connected to the second mounting plate 32. The second driving member 332 is disposed on the second mounting bracket 331, and at least one of the pressure plate 333 and the second pressure head 334 is drively connected to the second driving member 332. The second driving member 332 is used to drive the second pressure head 334 and the pressure plate 333 to move closer or further apart to press or release the film strip.

[0110] For example, in an optional embodiment, the second driving member 332 may be a gripper cylinder, with the pressure plate 333 and the second pressure head 334 respectively connected to one of the driving ends of the second driving member 332, and the second driving member 332 synchronously driving the pressure plate 333 and the second pressure head 334 to move closer to the center or to separate to both sides.

[0111] For example, in another alternative embodiment, the second driving member 332 may be a common linear cylinder, with one of the pressure plate 333 and the second pressure head 334 fixed to the second mounting bracket 331, and the second driving member 332 only drives the other of the pressure plate 333 and the second pressure head 334 to move, thereby causing the pressure plate 333 and the second pressure head 334 to move closer to the center or to separate to both sides.

[0112] As those skilled in the art know, when encapsulating the backplate, lower film, battery string, upper film, and glass plate, a through hole corresponding to each junction box needs to be provided in the middle of the backplate so that the leads on the junction box in the middle of the battery string can pass through the backplate. Figure 11 As shown, in order to prevent the inter-film strip 200 located in the middle position from blocking the through holes on the back plate 100, the commonly used method is to make clearance holes 201 on the inter-film strip 200 located in the middle position of the back plate 100, which correspond one-to-one with the through holes on the back plate.

[0113] When laying the inter-sheet membrane strip 200 at the middle position, or after laying the inter-sheet membrane strip 200 at the middle position, performing a hole-making operation on the inter-sheet membrane strip 200 will undoubtedly increase the structural complexity and equipment cost of the membrane strip processing device of this application, and affect the laying efficiency of the membrane strip processing device for the membrane strip.

[0114] Therefore, it is advisable to lay two inter-sheet membrane strips 200 in the middle of the back plate 100, with only a gap between the two inter-sheet membrane strips 200 to allow the junction box leads to pass through. In this way, there is no need to perform hole-making operations on the inter-sheet membrane strips 200 in the middle position.

[0115] Based on the above considerations, optionally, among the several membrane strips released by the membrane release section 1, the distance between the two middle membrane strips is smaller than the distance between the other two adjacent membrane strips, and the two membrane strip segments produced after the two middle membrane strips are cut are finally laid at the inter-sheet gap in the middle position of the back plate.

[0116] Because the gap between the two middle film strips is small, optionally, one of the middle film-pulling mechanisms 33 on the film-pulling section 3 is configured to simultaneously grip the two middle film strips from the film-dispensing section 1, while the remaining film-pulling mechanisms 33 are each configured to grip one film strip from the film-dispensing section 1. This ensures that the two middle film strips can be gripped synchronously and reduces the number of film-pulling mechanisms 33. Of course, each film-pulling mechanism 33 on the film-pulling section 3 can also be configured to grip one film strip from the film-dispensing section 1.

[0117] Similarly, optionally, one pressing and cutting mechanism 23 located in the middle of the pressing and cutting section 2 is configured to simultaneously press and cut the two middle membrane strips, while the remaining pressing and cutting mechanisms 23 are each configured to press and cut one membrane strip. This ensures that the two middle membrane strips can be pressed and cut synchronously, and reduces the number of pressing and cutting mechanisms 23. Of course, each pressing and cutting mechanism 23 on the pressing and cutting section 2 can also be configured to press and cut one membrane strip separately.

[0118] As described in the previous embodiments, in order to ensure that each film pulling mechanism 33 can clamp and pull out the film strip from the film dispensing part 1, and that the pulled-out film strip can enter the corresponding pressing and cutting mechanism 23, the third driving mechanism 24 needs to drive the first mounting plate 22 to reciprocate along the second direction, so as to drive each pressing and cutting mechanism 23 to switch to the corresponding avoidance position or working position simultaneously.

[0119] However, when the middle pressing and cutting mechanism 23 on the pressing and cutting part 2 is configured to simultaneously press and cut the two middle film strips, the length of the middle pressing and cutting mechanism 23 along the second direction is greater than that of the other pressing and cutting mechanisms 23. Simply relying on the third driving mechanism 24 to drive the first mounting plate 22 to move along the second direction to move the pressing and cutting mechanism 23 is insufficient because the movement stroke is not enough to allow it to switch to the avoidance position or the working position.

[0120] To solve this problem, such as Figures 4 to 5As shown, optionally, the clamping and cutting section 2 further includes a translation drive 25 disposed on the first mounting plate 22. The translation drive 25 is driven to the clamping and cutting mechanism 23 located in the middle. The translation drive 25 is used to drive the clamping and cutting mechanism 23 to move along the second direction to compensate for the movement stroke of the clamping and cutting mechanism 23 in the second direction, ensuring that it can switch between the corresponding avoidance position and the working position. Of course, the remaining clamping and cutting mechanisms are fixedly mounted on the first mounting plate 22.

[0121] The translation drive 25 can be, for example, a cylinder. The first mounting bracket 231 of the clamping and cutting mechanism 23 located in the middle is slidably connected to the first mounting plate 22 via a sliding connecting plate. The sliding connecting plate is connected to the telescopic rod of the cylinder. The cylinder drives the sliding connecting plate to slide back and forth on the first mounting plate 22 in the second direction, thereby driving the clamping and cutting mechanism 23 to move back and forth in the second direction.

[0122] like Figure 1 As shown, optionally, the film feeding unit 1 includes a film supply mechanism and a film dispensing mechanism. The film supply mechanism includes several feeding rollers 11, which are used to mount film strip rolls and rotate the film strip rolls to release the film strips. The film dispensing mechanism includes several film feeding heads 12 spaced apart along a second direction (e.g., the Y direction). Each film feeding head 12 corresponds to one of the feeding rollers 11. The film feeding head 12 is configured to receive the film strips released from the corresponding film strip rolls on the feeding rollers 11, guide the free end of the film strip to the pickup position, and then press the film strip, thereby enabling the film pulling unit 3 to clamp the free end of the film strip from the pickup position. The film pulling unit 3 is also configured to move synchronously with the pressing and cutting unit 3 to lay several film strip segments to a predetermined position.

[0123] By configuring the film feeding section 1, it is possible to simultaneously feed out several film strips, and to guide and position the free ends of several film strips at the pick-up position, so that the film pulling section 3 can pick up the free ends of several film strips from the pick-up position each time.

[0124] Since the film stretching section 3 can move synchronously with the pressing and cutting section 2, the film stretching section 3 and the pressing and cutting section 2 can automatically transport and lay several film strips to a predetermined position, further improving the automation level of film laying of the film strip processing equipment of this application.

[0125] Based on the same concept, this application also provides a film-laying device. For example... Figure 10 As shown, the film-laying equipment in this embodiment includes a supporting mechanism 10 and a film strip processing device 20. The film strip processing device 20 is the film strip processing device in any of the above embodiments, wherein:

[0126] The film strip processing device 20 is located above the support mechanism 10. The support mechanism 10 is used to support the backsheet of the photovoltaic module. The film strip processing device 20 and the support mechanism 10 are configured to move relative to each other. The pressing and cutting part 2 and the film pulling part 3 of the film strip processing device 20 are configured to lay a plurality of film strip segments onto the backsheet.

[0127] In one optional embodiment, the supporting mechanism 10 remains stationary, while the pressing and cutting section 2 and the film pulling section 3 of the film strip processing device 20 carry the processed film strip segments to a predetermined position above the supporting mechanism 10, releasing the film strip segments and thus laying them onto the back plate located on the supporting mechanism 10. To avoid excessive drop in film strip height causing misalignment, optionally, before the pressing and cutting section 2 and the film pulling section 3 release the film strip segments, the supporting mechanism 10 drives the back plate to rise and receive the film strips.

[0128] In another alternative embodiment, after the clamping and cutting section 2 and the film pulling section 3 of the film strip processing device 20 cooperate to pull out and cut the film strip to obtain several film strip segments, they remain stationary. The back plate is moved below the clamping and cutting section 2 and the film pulling section 3 by the carrying mechanism 10, and then the clamping and cutting section 2 and the film pulling section 3 release several film strip segments, thereby laying several film strip segments onto the back plate located on the carrying mechanism 10.

[0129] As can be seen, through the cooperation of the supporting mechanism 10 and the membrane strip processing device 20, the membrane laying equipment in this embodiment of the application realizes the automatic laying of several membrane strips onto the back plate, thereby improving the membrane laying efficiency.

[0130] 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.
