Description

Technical Field

[0001] This application relates to the technical field of photovoltaic module production equipment, and more specifically, to 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. Gaps exist between adjacent cells and between adjacent strings, making it difficult for light energy reaching these gaps to be directly absorbed or utilized. To improve light energy utilization, the industry uses reflective film strips applied to the backsheet at positions corresponding to the gaps between cells and strings. These strips reflect light energy reaching these gaps onto the glass plate, which then reflects it back onto the cells, thus fully utilizing the light energy in these gaps.

[0003] In production, the reflective film strip needs to be processed before being laid on the back panel, which involves cutting it to the required length and buffering it for later use. Therefore, an automated film strip processing device is needed to achieve automatic cutting and buffering of the reflective film strip. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a membrane strip processing device and a membrane laying equipment, which adopt the following technical solution:

[0005] In a first aspect, examples of this application provide a film strip processing apparatus, which includes a receiving mechanism and a film feeding mechanism, a cutting mechanism, and a traction mechanism arranged sequentially along a first horizontal direction, wherein:

[0006] The film feeding mechanism includes at least two film feeding heads arranged side by side along a second horizontal direction, each film feeding head being configured to feed out a film strip along a first horizontal direction, the second horizontal direction being perpendicular to the first horizontal direction;

[0007] The traction mechanism is configured to grip the end of each film strip from each film dispensing head and pull the film strip along a first horizontal direction, so that each film strip pulled out from the film dispensing head passes through the cutting mechanism.

[0008] The receiving mechanism includes a receiving platform and a first drive component, which is configured to drive the receiving platform to move in order to receive the membrane strips pulled out by the traction mechanism.

[0009] The cutting mechanism is configured to cut each membrane strip after it is received on the receiving platform, so as to obtain membrane strip segments on the receiving platform.

[0010] A membrane strip processing device is proposed herein, comprising a receiving mechanism and a film feeding mechanism, a cutting mechanism, and a traction mechanism arranged sequentially along a first horizontal direction. The main advantages of this design are:

[0011] The sequentially arranged film feeding mechanism, cutting mechanism, and traction mechanism ensure the continuity and efficiency of the film belt processing process, and this automated process significantly improves production efficiency.

[0012] The film-laying mechanism has at least two film-laying heads that can deliver at least two film strips along a first horizontal direction. The traction mechanism can clamp the ends of each film strip from the film-laying heads and pull each film strip along the first horizontal direction. The receiving mechanism, through the cooperation of the receiving platform and the first driving component, can drive the receiving platform to a designated position before the film strip is cut, so as to receive each film strip pulled out by the traction mechanism. In this way, the film strip can be received on the receiving platform during the cutting process, and can still be received on the receiving platform after the film strip is cut into film strip segments. Thus, the film strip processing device of this application realizes the simultaneous cutting, preparation and buffering of at least two film strip segments, with high film strip preparation efficiency, which prepares the film strip for subsequent film laying on the backsheet.

[0013] According to some examples of the first aspect of this application, the membrane dispensing head includes a carrier, a buffer assembly, and a guide plate, wherein:

[0014] The buffer assembly includes a guide wheel group, a buffer wheel, a support base, and a track. The guide wheel group includes a first guide wheel and a second guide wheel. The track is vertically mounted on the carrier. The support base is slidably mounted on the track in the vertical direction. The buffer wheel is mounted on the support base and located below the first guide wheel and the second guide wheel. The film strip released from the film roll passes around the first guide wheel, the buffer wheel, and the second guide wheel in sequence.

[0015] The guide plate is located behind the second guide wheel. The guide plate has a guide groove extending along the first horizontal direction. The membrane strip discharged from the second guide wheel enters the guide groove and is discharged through the guide groove.

[0016] The membrane dispensing head described here includes a carrier, a buffer assembly, and a guide plate, wherein the buffer assembly includes a guide wheel assembly, buffer wheels, a support base, and a track; the main advantage of this design is:

[0017] The buffer assembly, through the combination of guide wheel group, buffer wheel, support base and track, allows the buffer wheel to slide along the track under the tension of the membrane belt during unwinding, thus realizing the buffer function of the membrane belt; this can effectively adjust the tension of the membrane belt during processing, avoid membrane belt breakage or loosening caused by uneven tension, thereby improving the stability of membrane belt processing;

[0018] The buffer wheel is mounted on the support base and located below the guide wheel. The film belt can be smoothly released from the roll and pass through the guide wheel, ensuring the smoothness and straightness of the film belt during the conveying process, which helps to improve the accuracy of film belt cutting.

[0019] The guide plate has a guide groove extending along the first horizontal direction. After the film belt enters the guide groove, it can be guided and limited. This design further ensures the straightness and stability of the film belt on the guide plate, avoids the film belt from deviating and folding during the conveying process, and thus improves the accuracy and quality of film belt cutting.

[0020] According to some examples of the first aspect of this application, the film dispensing head further includes a clamping assembly, which includes a first driving member and a pressure applying member, wherein:

[0021] The pressure-applying component is installed on the drive end of the first drive component, which is used to drive the pressure-applying component to move toward or away from the guide plate to press the membrane tape onto the guide plate or release the membrane tape.

[0022] This document proposes that the film dispensing head also includes a clamping assembly, which comprises a first driving element and a pressure applying element. The main advantage of this design is that:

[0023] When the film strip needs to be pressed, the pressing assembly can firmly press the film strip onto the guide plate, ensuring the stability of the film strip during the cutting process, avoiding the shaking and deviation of the film strip, and also retaining the free end of the cut film strip, making it easy for the traction mechanism to clamp the end of the film strip again.

[0024] When the membrane belt needs to be released, the clamping assembly can loosen the membrane belt, allowing it to be smoothly pulled by the traction mechanism.

[0025] According to some examples of the first aspect of this application, the traction mechanism includes a first mounting bracket, a second drive assembly, and at least two clamping assemblies, wherein:

[0026] Each clamping component is arranged side by side at intervals on the first mounting frame along the second horizontal direction. Each clamping component is arranged in correspondence with the film feeding head. Each clamping component is used to clamp a film strip from the corresponding film feeding head.

[0027] The second drive component is configured to drive the first mounting bracket to move along a first horizontal direction.

[0028] The traction mechanism described herein includes a first mounting bracket, a second drive assembly, and at least two clamping assemblies. The main advantages of this design are:

[0029] Each clamping component is arranged side by side at intervals along the second horizontal direction and corresponds one-to-one with the film feeding head, enabling one-to-one clamping of the film strips released by the film feeding head. Under the drive of the second driving component, multiple film strips can be pulled synchronously and smoothly, facilitating the subsequent cutting of each film strip.

[0030] According to some examples of the first aspect of this application, the clamping assembly includes a first mounting base, a second drive member, a chuck, and a clamping plate, wherein:

[0031] The first mounting base is fixedly mounted on the first mounting bracket;

[0032] The second drive unit is mounted on the first mounting base and is drivenly connected to at least one of the chuck and the clamping plate for driving the chuck and the clamping plate to move closer to or away from the membrane strip to clamp or release the membrane strip.

[0033] A specific structure for a clamping assembly is provided, which uses a second driving member to drive the clamp and the clamping plate to move relative to each other in order to clamp or release the membrane tape. The structure is simple and easy to implement.

[0034] According to some examples of the first aspect of this application, the cutting mechanism includes a transverse drive, a second mounting frame and at least two shearing components. The second mounting frame is mounted on the drive end of the transverse drive. Each shearing component is spaced apart on the second mounting frame along the second horizontal direction. Each shearing component is arranged in a one-to-one correspondence with a clamping component. Each shearing component is used to cut the film strip clamped by the corresponding clamping component.

[0035] The lateral drive is used to drive the second mounting bracket to reciprocate along the second horizontal direction, so as to drive each shearing component to switch synchronously between the corresponding avoidance position and working position.

[0036] When each shearing component is switched to the corresponding avoidance position, each shearing component is offset from the straight line where the corresponding clamping component and the film dispensing head are located in the second horizontal direction, so that each clamping component can clamp the film strip from the corresponding film dispensing head.

[0037] When each shearing component is switched to its corresponding working position, each shearing component is aligned with the straight line of the corresponding clamping component and the film delivery head in the second horizontal direction, and the film strip pulled by each clamping component enters the corresponding shearing component.

[0038] The specific structure of the cutting mechanism is presented here, including a transverse drive, a second mounting bracket, and multiple shearing components. The main advantages of this design are:

[0039] The transverse drive can drive the second mounting bracket to reciprocate along the second horizontal direction, so that each shearing component can switch synchronously between the corresponding avoidance position and working position. This ensures the efficiency and synchronization of the cutting process and improves production efficiency.

[0040] When the shearing components switch to the avoidance position, each shearing component is offset from the straight line of the clamping components and the film feeding head in the second horizontal direction. This allows the clamping components to smoothly clamp the film strip from the film feeding head, avoiding interference from the cutting mechanism during the clamping process.

[0041] When the shearing components are switched to the working position, the straight line of each shearing component, clamping component, and film dispensing head is aligned in the second horizontal direction. This allows each film strip pulled out by the traction mechanism to enter the corresponding shearing component, facilitating subsequent film strip cutting operations.

[0042] According to some examples of the first aspect of this application, the shearing assembly includes a second mounting base, a third drive member, a first cutting edge, and a second cutting edge, wherein:

[0043] The second mounting base is fixedly installed on the second mounting bracket;

[0044] The third driving member is mounted on the second mounting base and is drivenly connected to at least one of the first and second cutting edges to drive the first and second cutting edges closer or further away in order to cut or avoid the membrane strip passing between the first and second cutting edges.

[0045] A specific structure for a shearing assembly is provided, which uses a third driving member to drive the first and second cutting edges to move relative to each other in order to cut the film strip. The structure is simple and easy to implement.

[0046] According to some examples of the first aspect of this application, the first driving component is used to drive the receiving platform to lift and move along the first horizontal direction. At least two adsorption groups are arranged at intervals along the second horizontal direction on the receiving surface of the receiving platform. Each adsorption group includes a plurality of adsorption holes or a plurality of suction cups arranged at intervals along the first horizontal direction. Each adsorption group is used to adsorb a membrane strip.

[0047] The specific structure of the receiving platform is described here. At least two adsorption groups are arranged on the receiving surface of the platform, and it has lifting and horizontal movement functions. The main advantage of this design is:

[0048] The first drive assembly can drive the receiving platform to lift and move along the first horizontal direction. This design allows the receiving platform to move under the membrane belt along the membrane belt pulling direction and receive the membrane belt. This flexibility is suitable for receiving membrane belts of different lengths.

[0049] Multiple adsorption groups are spaced apart along the second horizontal direction on the receiving platform. Each adsorption group includes multiple adsorption holes or suction cups. Each membrane strip is adsorbed one by one through the adsorption holes or suction cups, which can ensure the stable fixation of each membrane strip on the receiving platform and ensure that the position of the membrane strip will not shift after it is cut.

[0050] In a second aspect, an example of this application provides a film-laying apparatus, which includes a carrying device, a conveying and heating device, and at least one of the aforementioned film strip processing devices, wherein:

[0051] The support device is used to transport and / or support the backsheet of the photovoltaic module;

[0052] The conveying and heating device is used to convey and lay the membrane tape segments on the receiving platform in the membrane tape processing device onto the back plate, and to heat the membrane tape segments so that the membrane tape segments adhere to the back plate.

[0053] A film-laying device is proposed herein, comprising a support device, a conveying and heating device, and a film strip handling device. The main advantages of this design are:

[0054] The carrier device can transport and / or carry the backsheet of the photovoltaic module, thus providing support for the backsheet to be laminated;

[0055] The membrane strip processing device can automatically cut and buffer at least two membrane strips;

[0056] The conveying and heating device can convey and lay the film strip segments on the receiving platform in the film strip processing device onto the back plate, while heating the film strip segments so that they can be firmly bonded to the back plate. This application realizes full automation of the process from film strip cutting to laying and pasting through the coordinated work of the film strip processing device, the bearing device, and the conveying and heating device, thereby improving production efficiency and reducing manual intervention.

[0057] According to some examples of the second aspect of this application, there are two membrane strip processing devices, with the receiving platforms of the two membrane strip processing devices arranged adjacent to each other, and the conveying heating device is used to simultaneously convey and bond the membrane strip segments on the two receiving platforms to the back plate.

[0058] This paper proposes that the number of membrane strip handling devices in the membrane laying equipment be two, and that the two receiving platforms be arranged adjacent to each other. The main advantage of this design is that:

[0059] The parallel operation of two membrane strip processing devices can significantly improve the efficiency of membrane strip preparation and shorten the production cycle;

[0060] The conveying and heating device can simultaneously convey and bond membrane segments from two receiving platforms to the backing plate, further improving the efficiency and quality of membrane laying.

[0061] The adjacent arrangement of the two receiving platforms brings the two sets of buffered membrane segments closer together, making it easier to transport the heating device while simultaneously transporting the two sets of membrane segments. Attached Figure Description

[0079] 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.

[0080] like Figure 1 As shown, the membrane strip processing device 10 in this embodiment includes a receiving mechanism 4 and a receiving mechanism along a first horizontal direction (e.g., Figure 1 The film-laying mechanism 1, the cutting mechanism 3, and the traction mechanism 2 are arranged sequentially in the X direction (as shown in the image), wherein:

[0081] The membrane placement mechanism 1 includes at least two (e.g.) Figure 2 (7 of them) along the second horizontal direction (e.g.) Figure 2 The film dispensing heads 101 are arranged side by side in the Y direction, and each film dispensing head 101 is configured to deliver a film strip along a first horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction.

[0082] The traction mechanism 2 is configured to grip the end of each film strip from each film dispensing head 101 and pull the film strip along the first horizontal direction so that each film strip pulled out from the film dispensing head 101 passes through the cutting mechanism 3.

[0083] The receiving mechanism 4 includes a receiving platform 401 and a first driving component 402. The first driving component 402 is configured to drive the receiving platform 401 to move in order to receive the membrane strips pulled out by the traction mechanism 2.

[0084] The cutting mechanism 3 is configured to cut each membrane strip after receiving each membrane strip on the receiving platform 401, so as to obtain membrane strip segments on the receiving platform 401.

[0085] Optionally, the working process of the membrane strip processing device 10 of this application is as follows:

[0086] First, a membrane strip is respectively guided out along the first horizontal direction by at least two membrane delivery heads 101;

[0087] Next, the traction mechanism 2 clamps the end of each film strip from each film dispensing head 101 and moves along the first horizontal direction, so that the end of the clamped film strip is away from the outlet end of the film dispensing head 101, and pulls the film strip out and through the cutting mechanism 3.

[0088] After the membrane strip is pulled out to the specified length, the receiving platform 401 in the receiving mechanism 4 moves to the bottom of the pulled-out membrane strip through the first drive component 402 to receive each membrane strip pulled out by the traction mechanism 2.

[0089] Finally, the cutting mechanism 3 cuts the membrane strip, thereby obtaining the cut membrane strip segment on the receiving platform 401 in the receiving mechanism 4.

[0090] The film strip processing device 10 includes a receiving mechanism 4 and a film feeding mechanism 1, a cutting mechanism 3 and a traction mechanism 2 arranged sequentially along a first horizontal direction; the sequential arrangement of the film feeding mechanism 1, the cutting mechanism 3 and the traction mechanism 2 ensures the continuity and efficiency of the film strip processing process, and this automated process significantly improves production efficiency.

[0091] At least two film-laying heads 101 in the film-laying mechanism 1 can deliver at least two film strips along the first horizontal direction. The traction mechanism 2 can clamp the ends of each film strip from the film-laying head 101 and pull each film strip along the first horizontal direction. The receiving mechanism 4, through the cooperation of the receiving platform 401 and the first driving component 402, can drive the receiving platform 401 to move to a designated position before the film strip is cut, so as to receive each film strip pulled out by the traction mechanism 2. In this way, the film strip can be received on the receiving platform 401 when it is cut, and can still be received on the receiving platform 401 after the film strip is cut into film strip segments. Thus, the film strip processing device 10 of this application realizes the simultaneous cutting, preparation and buffering of at least two film strip segments, with high film strip preparation efficiency, and prepares the film strip for subsequent film laying on the backsheet.

[0092] by Figure 9 Taking the backplate 100 shown as an example, seven inter-layer membrane strips 200 need to be laid on its first half (such as the upper half) and its second half (such as the lower half), and 25 inter-sheet membrane strips 300 also need to be laid on the entire backplate. The inter-layer membrane strips 200 and the inter-sheet membrane strips 300 intersect perpendicularly. The membrane strip processing device of this application embodiment can be used to prepare and buffer some or all of the inter-layer membrane strips 200 required for backplate lamination, and can also be used to prepare and buffer some or all of the inter-sheet membrane strips 300 required for backplate lamination. Correspondingly, the number of membrane placement heads 101 can be selectively set according to the actual number of membrane segments to be prepared and buffered. For example, when it is necessary to prepare and buffer the inter-series membrane segments 200 required for one half, the number of membrane placement heads 101 can be set to 7, thereby realizing the preparation and buffering of all inter-series membrane segments 200 on one half of the backplane; when it is necessary to prepare and buffer all inter-sheet membrane segments 300, the number of membrane placement heads 101 can be set to 25, thereby realizing the preparation and buffering of all inter-sheet membrane segments 300 on the backplane. Optionally, such as Figure 2 As shown, the film dispensing head 101 includes a carrier 102, a buffer assembly 103, and a guide plate 110, wherein:

[0093] The buffer assembly 103 includes a guide wheel group 104, a buffer wheel 107, a support base 108, and a track 109. The guide wheel group 104 includes a first guide wheel 105 and a second guide wheel 106. The track 109 is vertically disposed on the carrier 102. The support base 108 is slidably mounted on the track 109 in the vertical direction. The buffer wheel 107 is mounted on the support base 108 and located below the first guide wheel 105 and the second guide wheel 106. The film strip released from the film strip roll passes sequentially around the first guide wheel 105, the buffer wheel 107, and the second guide wheel 106.

[0094] The guide plate 110 is located behind the second guide wheel 106. The guide plate 110 has a guide groove 111 extending in the first horizontal direction. The membrane strip led out by the second guide wheel 106 enters the guide groove 111 and is led out through the guide groove 111.

[0095] Here, the buffer wheel 107 is configured to buffer the film strip fed from the film roll as it moves along the track 109 away from the first guide wheel 105 and the second guide wheel 106. The buffer wheel 107 is also configured to move along the track 109 toward the first guide wheel 105 and the second guide wheel 106 to release the buffered film strip when the film strip is being pulled. The slidable mounting of the buffer wheel 107 on the track 109 allows it to absorb excess film strip or supplement insufficient film strip when the film roll's feeding speed does not match the pulling speed of the traction mechanism. This prevents stretching or wrinkling of the film strip during the unloading process, ensuring film strip quality.

[0096] In the unwinding head 101, the buffer assembly 103, through the combination of guide wheel group 104, buffer wheel 107, support seat 108 and track 109, allows the buffer wheel to slide along the track under the tension of the film belt during unwinding, thus realizing the buffering function of the film belt; this can effectively adjust the tension of the film belt during the processing, avoid film belt breakage or loosening caused by uneven tension, thereby improving the stability of film belt processing;

[0097] The buffer wheel 107 is mounted on the support base 108 and located below the guide wheel. The film belt can be smoothly released from the film belt roll and pass through the guide wheel, ensuring the smoothness and straightness of the film belt during the conveying process, which helps to improve the accuracy of film belt cutting.

[0098] The guide plate 110 has a guide groove 111 extending along the first horizontal direction. After the film belt enters the guide groove, it can be guided and limited. This design further ensures the straightness and stability of the film belt on the guide plate 110, avoids the film belt from shifting and folding during the conveying process, and thus improves the accuracy and quality of film belt cutting.

[0099] Optional, such as Figure 2As shown, the film dispensing head 101 also includes a pressing assembly 112, which includes a first driving member 113 and a pressure applying member 114, wherein:

[0100] The pressure-applying member 114 is installed at the driving end of the first driving member 113. The first driving member 113 is used to drive the pressure-applying member 114 to move toward or away from the guide plate 110 to press the membrane tape onto the guide plate 110 or release the membrane tape.

[0101] Optionally, the first driving member 113 is configured to drive the pressure applying member 114 to approach or move away from the membrane strip in the guide groove 111 on the guide plate 110, thereby applying pressure or releasing pressure on the membrane strip in the guide groove 111. The introduction of the clamping assembly 112 facilitates the cutting of the membrane strip. The external traction mechanism 2 clamps the end of the membrane strip from the film dispensing head 101 and pulls it. After pulling out a certain length, the membrane strip is pressed against the guide plate 110 by the clamping assembly 112, and the external cutting mechanism 3 can then cut the membrane strip. The free end of the membrane strip can still be held at the film dispensing head 101 to wait for the next pull.

[0102] Optionally, the first driving component 113 may be a cylinder, linear motor or other driving component.

[0103] In the film feeding head 101, when the film belt needs to be pressed, the pressing component 112 can firmly press the film belt onto the guide plate 110 to ensure the stability of the film belt during the cutting process and avoid the film belt shaking and deviation; when the film belt needs to be released, the pressing component 112 can loosen the film belt so that the film belt can be smoothly pulled by the traction mechanism 2.

[0104] Optional, such as Figure 3 As shown, the traction mechanism 2 includes a first mounting bracket 201, a second drive assembly, and at least two clamping assemblies 202, wherein:

[0105] Each clamping component 202 is arranged side by side at intervals on the first mounting frame 201 along the second horizontal direction. Each clamping component 202 is arranged in a one-to-one correspondence with the film dispensing head 101. Each clamping component 202 is used to clamp a film strip from the corresponding film dispensing head 101.

[0106] The second drive component is configured to drive the first mounting bracket 201 to move along a first horizontal direction.

[0107] The clamping component 202 in the traction mechanism 2 can move closer to or further away from the film-laying head 101 by moving the first mounting bracket 201 along the first horizontal direction, thereby adjusting the distance between the clamping component 202 and the corresponding film-laying head 101. This makes it easier for the clamping component 202 to approach the film-laying head 101 to clamp the end of the film strip, and to move away from the film-laying head 101 after clamping the end of the film strip to pull out the film strip.

[0108] Figure 3The traction mechanism 2 shown includes a first mounting frame 201, a second drive assembly, and at least two clamping assemblies 202. Each clamping assembly 202 is arranged side by side at intervals along the second horizontal direction and corresponds one-to-one with the film feeding head 101. It can achieve one-to-one clamping of the film strips released by the film feeding head 101. Under the drive of the second drive assembly, it can achieve synchronous and stable pulling of multiple film strips, which facilitates the subsequent cutting of each film strip.

[0109] Optional, such as Figure 4 As shown, the clamping assembly 202 includes a first mounting base 203, a second driving member 204, a chuck 205, and a clamping plate 206, wherein:

[0110] The first mounting base 203 is fixedly mounted on the first mounting bracket 201;

[0111] The second drive member 204 is mounted on the first mounting base 203 and is drivenly connected to at least one of the chuck 205 and the clamping plate 206 for driving the chuck 205 and the clamping plate 206 to move closer to or away from the membrane strip to clamp or release it.

[0112] The second driving component 204 can be driven to the chuck 205 and the clamp 206 in the following three ways:

[0113] In the first configuration, the second driving member 204 is only connected to the chuck 205 for driving. In this configuration, the clamping plate 206 is fixedly installed, and the second driving member 204 drives the chuck 205 to move closer to or away from the clamping plate 206. Optionally, the second driving member 204 can be a linear actuator such as a cylinder to drive the chuck 205 to move linearly closer to or away from the clamping plate 206. Alternatively, the second driving member 204 can be a rotary driving member to drive the clamping end of the chuck 205 to rotate toward or away from the clamping plate 206 to clamp or release the film strip.

[0114] The second configuration: The second driving member 204 is only connected to the clamping plate 206 for driving. In this case, the chuck 205 is fixedly set, and the second driving member 204 drives the clamping plate 206 to move closer to or away from the chuck 205. Optionally, the second driving member 204 can be a linear actuator such as a cylinder to drive the clamping plate 206 to move linearly closer to or away from the chuck 205. Alternatively, the second driving member 204 can be a rotary driving member to drive the clamping end of the clamping plate 206 to rotate toward or away from the chuck 205 to clamp or release the membrane tape.

[0115] The third form: the second driving component 204 is drivenly connected to the chuck 205 and the clamping plate 206. Optionally, the second driving component 204 is a gripper cylinder, and the chuck 205 and the clamping plate 206 are respectively installed on the two driving ends of the gripper cylinder.

[0116] Optionally, in one implementation, such as Figure 4As shown, the second drive component 204 and the clamping plate 206 are fixedly mounted on the first mounting base 203;

[0117] The driving end of the second driving member 204 is connected to the first connecting block 207. The first end of the chuck 205 is rotatably connected to the first connecting block 207, and the middle part of the chuck 205 is rotatably connected to the clamping plate 206. The second driving member 204 is configured to drive the first connecting block 207 to move, so as to drive the second end of the chuck 205 to move toward or away from the clamping plate 206 to clamp or release the membrane tape.

[0118] Using the second driving component 204, the angle between the chuck 205 and the clamping plate 206 can be adjusted so that the chuck 205 and the clamping plate 206 are in an open state or a clamping state. When the chuck 205 and the clamping plate 206 are in the open state, the clamping component 202 moves closer to the film feeding head 101 so that the end of the film strip enters between the chuck 205 and the clamping plate 206. When the end of the film strip enters between the chuck 205 and the clamping plate 206, the angle between the chuck 205 and the clamping plate 206 is reduced, and the chuck 205 and the clamping plate 206 are switched to the clamping state, clamping the film strip between the chuck 205 and the clamping plate 206.

[0119] Optional, please continue reading Figure 3 The cutting mechanism 3 includes a transverse drive 301, a second mounting frame 302 and at least two shearing components 303. The second mounting frame 302 is mounted on the drive end of the transverse drive 301. Each shearing component 303 is spaced apart on the second mounting frame 302 along the second horizontal direction. Each shearing component 303 is correspondingly arranged with a clamping component 202. Each shearing component 303 is used to cut the film strip clamped by the corresponding clamping component 202.

[0120] The lateral drive 301 is used to drive the second mounting bracket 302 to reciprocate along the second horizontal direction, so as to drive each shearing component 303 to switch synchronously between the corresponding avoidance position and working position.

[0121] When each shearing component 303 is switched to the corresponding avoidance position, each shearing component 303 is offset from the straight line where the corresponding clamping component 202 and the film dispensing head 101 are located in the second horizontal direction, so that each clamping component 202 can clamp the film strip from the corresponding film dispensing head 101.

[0122] When each shearing component 303 is switched to its corresponding working position, each shearing component 303 is aligned with the straight line of the corresponding clamping component 202 and the film dispensing head 101 in the second horizontal direction, and the film strip pulled by each clamping component 202 enters the corresponding shearing component 303.

[0123] First, adjust each shearing component 303 of the cutting mechanism 3 to a clearance position, so that each shearing component 303 is aligned with the corresponding clamping component 202 and the film feeding head 101 on a straight line (e.g., Figure 3 The straight line S in the middle is offset in the second horizontal direction (e.g., the Y direction) to ensure that the clamping assembly 202 can smoothly clamp the end of the film strip from the film feeding head 101; after the film strip is pulled to the designated position by the traction mechanism 2, the transverse drive 301 drives the second mounting frame 302 to move along the second horizontal direction, so that the shearing assembly 303 switches from the avoidance position to the working position; when all the shearing assemblies 303 are switched to the working position, each shearing assembly 303 is aligned with the corresponding film feeding head 101 and clamping assembly 202 in the second horizontal direction, ready for cutting.

[0124] In the cutting mechanism 3, the transverse drive 301 can drive the second mounting bracket 302 to reciprocate along the second horizontal direction, so that each cutting component 303 can switch synchronously between the corresponding avoidance position and working position. This ensures the efficiency and synchronization of the cutting process and improves production efficiency.

[0125] When the shearing assembly 303 switches to the avoidance position, each shearing assembly 303 is offset from the straight line of the clamping assembly 202 and the film dispensing head 101 in the second horizontal direction. This allows the clamping assembly 202 to smoothly clamp the film strip from the film dispensing head 101, avoiding interference from the cutting mechanism 3 during the clamping process.

[0126] When the shearing assembly 303 is switched to the working position, each shearing assembly 303 is aligned with the straight line of the clamping assembly 202 and the film dispensing head 101 in the second horizontal direction. This allows each film strip pulled out by the traction mechanism 2 to enter the corresponding shearing assembly 303, which facilitates the subsequent cutting operation of the film strip.

[0127] Optional, such as Figure 5 As shown, the shearing assembly 303 includes a second mounting base 304, a third driving member 305, a first cutting edge 306, and a second cutting edge 307, wherein:

[0128] The second mounting base 304 is fixedly mounted on the second mounting bracket 302;

[0129] The third driving member 305 is mounted on the second mounting base 304. The third driving member 305 is drivenly connected to at least one of the first cutting edge 306 and the second cutting edge 307, and is used to drive the first cutting edge 306 and the second cutting edge 307 to move closer or further away, so as to cut or avoid the membrane strip passing between the first cutting edge 306 and the second cutting edge 307.

[0130] The driving connection between the third driving component 305 and the first cutting edge 306 and the second cutting edge 307 can be achieved in the following three ways:

[0131] In the first configuration, the third driving member 305 is only connected to the first cutting edge 306, while the second cutting edge 307 is fixedly mounted. The third driving member 305 drives the first cutting edge 306 to move closer to or away from the second cutting edge 307. Optionally, the third driving member 305 can be a linear actuator such as a cylinder to drive the first cutting edge 306 to move linearly closer to or away from the second cutting edge 307. Alternatively, the third driving member 305 can be a rotary drive to drive the first cutting edge 306 to rotate toward or away from the second cutting edge 307 to cut the film strip.

[0132] The second configuration: The third driving member 305 is only connected to the second cutting edge 307. In this configuration, the first cutting edge 306 is fixed, and the third driving member 305 drives the second cutting edge 307 to move closer to or away from the first cutting edge 306. Optionally, the third driving member 305 can be a linear actuator such as a cylinder to drive the second cutting edge 307 to move linearly closer to or away from the first cutting edge 306. Alternatively, the third driving member 305 can be a rotary driving member to drive the second cutting edge 307 to rotate toward or away from the first cutting edge 306 to cut the film strip.

[0133] The third form: the third driving component 305 is drivenly connected to the first cutting edge 306 and the second cutting edge 307. Optionally, the third driving component 305 is a gripper cylinder, and the first cutting edge 306 and the second cutting edge 307 are respectively installed on the two driving ends of the gripper cylinder.

[0134] Optional, such as Figure 5 As shown, the shearing assembly 303 also includes a second connecting block 308, the first cutting edge 306 is a moving edge, and the second cutting edge 307 is a stationary edge, wherein:

[0135] The third drive unit 305 and the stationary blade are mounted on the second mounting base 304;

[0136] The driving end of the third driving member 305 is connected to the second connecting block 308. The first end of the moving blade is rotatably connected to the second connecting block 308, and the middle part of the moving blade is rotatably connected to the stationary blade. The third driving member 305 is configured to drive the second connecting block 308 to move so that the second end of the moving blade moves toward or away from the stationary blade to cut or avoid the membrane strip passing between the moving blade and the stationary blade.

[0137] The moving blade and stationary blade in the shearing assembly 303 are initially in the open state, ready for the film strip cutting operation; when the film strip enters between the moving blade and the stationary blade, the second end of the moving blade moves closer to the stationary blade under the drive of the third drive member 305, cutting the film strip located between the moving blade and the stationary blade to obtain a film strip segment; after the cutting is completed, the third drive member 305 drives the second end of the moving blade away from the stationary blade, returning to the open state, ready for the next cutting.

[0138] Optional, such as Figure 6As shown, the first driving component 402 is used to drive the receiving platform 401 to rise and fall and move along the first horizontal direction. At least two adsorption groups 405 are arranged at intervals along the second horizontal direction on the receiving surface of the receiving platform 401. Each adsorption group 405 includes a plurality of adsorption holes and / or a plurality of suction cups arranged at intervals along the first horizontal direction. Each adsorption group 405 is used to adsorb a membrane strip.

[0139] Optional, such as Figure 7 As shown, the first drive assembly 402 includes a transverse drive 403 and a lifting drive 404. The transverse drive 403 is used to drive the receiving platform 401 to move along the first horizontal direction, and the lifting drive 404 is used to drive the receiving platform 401 to rise and fall. The transverse drive 403 and the lifting drive 404 can be any kind of linear drive, such as a cylinder or a linear motor.

[0140] The receiving platform 401 has at least two adsorption groups 405 on its receiving surface and is equipped with lifting and horizontal movement functions; the main advantage of this design is:

[0141] The first drive assembly 402 can drive the receiving platform 401 to rise and fall and move along the first horizontal direction. This design allows the receiving platform 401 to move under the membrane belt along the membrane belt pulling direction and receive the membrane belt. This flexibility is suitable for receiving membrane belts of different lengths.

[0142] Multiple adsorption groups 405 are spaced apart along the second horizontal direction on the receiving platform 401. Each adsorption group 405 includes multiple adsorption holes or suction cups. The adsorption holes or suction cups are used to adsorb each membrane strip one by one, which can ensure the stable fixation of each membrane strip on the receiving platform 401 and ensure that the position of the membrane strip will not shift after it is cut.

[0143] like Figure 8 As shown, the film-laying equipment in this embodiment includes a carrying device 20, a conveying and heating device 30, and at least one of the aforementioned film strip processing devices 10, wherein:

[0144] The support device 20 is used to transport and / or support the backsheet of the photovoltaic module;

[0145] The conveying and heating device 30 is used to convey and lay each membrane strip segment on the receiving platform 401 in the membrane strip processing device 10 onto the back plate, and to heat the membrane strip segments so that the membrane strip segments adhere to the back plate.

[0146] Optionally, the carrying device 20 can be a belt conveyor or a carrying platform; the conveying and heating device 30 includes a conveying component and a heating component; the conveying component is used to convey and lay each membrane belt segment on the receiving platform 401 in the membrane belt processing device 10 onto the back plate; the heating component is used to heat the membrane belt segments laid on the back plate so that the membrane belt segments adhere to the back plate.

[0147] Optionally, the handling component can use suction cups or other adsorption structures to adsorb each membrane strip segment, thereby picking up the membrane strip segment and laying it on the back plate; the heating component can use infrared heating, local heating with a spot heating head, or overall heating with a heating plate, as long as the membrane strip can be heated and adhered to the back plate.

[0148] The film-laying equipment includes a carrier device 20, a conveying and heating device 30, and a film strip processing device 10. The main advantages of this design are:

[0149] The carrier device 20 can transport and / or carry the backsheet of the photovoltaic module, thus providing support for the backsheet to be laminated.

[0150] The membrane strip processing device 10 can automatically cut and buffer at least two membrane strips;

[0151] The conveying and heating device 30 can convey and lay the film strip segment on the receiving platform 401 in the film strip processing device 10 onto the back plate, and at the same time heat the film strip segment so that the film strip segment can be firmly bonded to the back plate. Through the coordinated work of the film strip processing device 10, the carrying device 20, and the conveying and heating device 30, this application realizes the full automation of the process from film strip cutting to laying and pasting, improves production efficiency, and reduces manual intervention.

[0152] Optional, with Figure 9 Taking the backsheet shown as an example, its first and second halves each require the laying of 7 inter-membrane strip segments 200. To improve the laying efficiency of the inter-membrane strip segments 200 on the backsheet, please refer to [link / reference needed]. Figure 8 and Figure 1 The film-laying equipment of this application embodiment includes two film strip processing devices 10. Each film strip processing device 10 includes a receiving mechanism 4 and a film-laying mechanism 1, a cutting mechanism 3 and a traction mechanism 2 arranged sequentially along a first horizontal direction (e.g., the X direction). The receiving platforms 401 of the two film strip processing devices 10 are arranged adjacent to each other. The conveying heating device 30 is used to simultaneously convey and bond two sets of inter-string film strip segments 200 on the two receiving platforms 401 to the back plate 100 located on the carrier device 20.

[0153] By setting the number of film-laying heads 101, such as 7 on each side, this film-laying equipment with two film belt processing devices 10 can simultaneously complete tasks such as... Figure 9The two sets of inter-series membrane segments 200 shown are prepared and buffered. Subsequently, the conveying heating device 30 can simultaneously convey and attach the two sets of inter-series membrane segments 200 to the back plate, thereby improving the back plate bonding efficiency.

[0154] The adjacent arrangement of the two receiving platforms 401 brings the two sets of buffered inter-membrane tape segments 200 closer together, making it easier to transport the heating device 30 to transport the two sets of inter-membrane tape segments 200 at the same time. Furthermore, by controlling the movement of the two receiving platforms 401 along the first horizontal direction, the spacing between the two sets of inter-membrane tape segments 200 can be adjusted to meet the laying position requirements of the two sets of inter-membrane tape segments 200 on the back plate.
