[0002] When manufacturing BC photovoltaic modules, film strips are pasted at the gaps between battery strings to improve the yield rate of the modules in the lamination process stage and improve the appearance of the modules at the same time. In the prior art, prefabricated film strips are usually stretched and laid, which requires a corresponding number of film supply, film pulling, film cutting and other equipment. The structure is complex and the density is too high, resulting in a sharp increase in the manufacturing cost and maintenance cost of the equipment, and the difficulty of maintenance and repair is large.

[0003] Using a whole film to prepare film strips can effectively simplify the equipment structure and reduce the equipment manufacturing cost. When using a whole film to prepare film strips, a film connecting platform is needed to cooperate with a cutting tool to complete the preparation of multiple film strips. To realize the transfer of the connected film strips, the cutting tool can be removed and a transfer device can be moved in, or the connected film strips can be transferred from the cutting position to the grasping position of the transfer device. The second method is more convenient for simplifying the structure. In the above two methods, to ensure that the position dimensions before and after the film strip spacing are consistent with the preset position dimensions, the film connecting platform also needs to have the function of short-range spacing.

Detailed implementation manners

[0029] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] In addition, it should be noted that components with the same function in this application can be implemented using different structural solutions. The component names are suffixed with "A", "B", "C", and "D" to distinguish different structural solutions.

[0033] First of all, it should be noted that compared with the prior art, using a whole film to prepare film strips can effectively simplify the equipment structure and reduce the equipment manufacturing cost. The series-connected film receiving platform of the present utility model can be applied to a film pasting device for cutting a whole film. When using a whole film to prepare film strips, this series-connected film receiving platform can cooperate with a cutting tool to complete the preparation of series-connected film strips and realize the transfer of series-connected film strips. At the same time, the film receiving platform has both the functions of transfer and short-range separation to ensure that the position dimensions of the film strips before and after separation are the same as the preset position dimensions. Here, the transfer function means transferring the film strips to avoid the cutting device, facilitating the transfer device to grab the film strips; the short-range separation function means separating the film strips by a short distance. Since the width dimension of the film strips is small, it is necessary to grab and transfer the closely adjacent film strips. When the series-connected film strips are not separated by a short distance, it is difficult for the transfer device to pick up and place the film strips, and it is very easy to cause the deviation of the film strip position, affecting the dimensional accuracy of subsequent film pasting.

[0034] Embodiment 1

[0035] In this embodiment, the second film strip transfer method is adopted, that is, the method of transferring the series-connected film strips from the cutting position to the grasping position of the transfer device.

[0036] As Figures 1-3 shown, a series-connected film receiving platform includes a base 100 and a separation component 300. The separation component 300 is installed on the base 100.

[0037] Among them, the distance separation component 300 includes a support plate 310, a carrier strip 320, a deflector plate A 331, a deflector plate B 332, and a distance separation drive 340. The carrier strip 320 is installed on the support plate 310 through a linear guide 350. The deflector plate A 331 and the deflector plate B 332 are arranged between the support plate 310 and the carrier strip 320. Specifically, the deflector plate A 331 is fixed to the support plate 310, and the deflector plate B 332 is movably arranged on the support plate 310. The deflector plate A 331 and the deflector plate B 332 are arranged in a stacked form. A traction groove A 3311 is provided on the deflector plate A 331, and a traction groove B 3321 matching the traction groove A 3311 is provided on the deflector plate B 332. A guide member 321 penetrating through the traction groove A 3311 and the traction groove B 3321 is provided on the carrier strip 320. During installation, the guide member 321 penetrates through the traction groove B 3321 from top to bottom and penetrates into the traction groove A 3311. During operation, the deflector plate B 332 is driven to move by the distance separation drive 340, and the deflector plate B 332 drives the guide member 321 to move through the traction groove B 3321, realizing the position conversion of the carrier strip 320 between the converging position and the distance separation position. When the carrier strip 320 is located at the converging position / distance separation position, one top end of the traction groove A 3311 and the inner wall of the traction groove B 3321 abut against the guide member 321 in opposite directions.

[0038] Meanwhile, the distance separation component 300 further includes a transfer drive 200. The transfer drive 200 is installed on the base 100, and the output end of the transfer drive 200 is connected to the support plate 310. The transfer drive 200 can drive the support plate 310 to move relative to the base 100 to realize the position conversion of the distance separation component 300 between the film cutting position and the film taking position. By increasing the structural strength of the base 100, the stability of the distance separation component 300 during the position conversion process can be ensured.

[0039] The above-mentioned transfer drive 200 and distance separation drive 340 are preferably drive components composed of a servo motor and a ball screw. Of course, other drive components capable of realizing telescopic functions, such as air cylinders, can also be selected. The present utility model does not make specific limitations in this regard.

[0040] In addition, in this embodiment, the guide member 321 is preferably an external spiral bearing matching the traction groove A 3311 and the traction groove B 3321. Of course, it can also be a guide post or other components capable of restricting movement in the traction groove A 3311 and the traction groove B 3321 matching the traction groove A 3311 and the traction groove B 3321. The present utility model does not make specific limitations on the guide member 321.

[0041] To better understand the solution in this embodiment, the following details the specific process of the distance separation action of the carrier strip 320.

[0042] First: As Figure 3As shown, the length direction of the traction groove A3311 is parallel to the moving direction of the support plate 310, and the length direction of the traction groove B3321 is parallel to the length direction of the traction groove A3311. When the bearing bar 320 is in the converging position / the separating position, under the action of the separating drive 340, one end of the traction groove A3311 and the inner wall of the traction groove B3321 abut against the guide member 321 in opposite directions. That is to say, at this time, the guide member 321 is located at the only upper and lower overlapping hole part of the traction groove A3311 and the traction groove B3321, and the traction groove A3311 and the traction groove B3321 jointly act on the guide member 321 in the opposite direction to clamp and fix the guide member 321. Thus, the position of the bearing bar 320 in the converging position and the separating position is ensured to be fixed; when the bearing bar 320 moves from the converging position to the separating position / from the separating position to the converging position, the separating drive 340 drives the dial B332 to move, and the end of the traction groove B3321 abutting against the guide member 321 moves away from the guide member 321. When the other end of the traction groove B3321 abuts against the guide member 321, the lower part of the guide member 321 moves in the traction groove A3311 until the guide member 321 abuts against the other ends of the traction groove A3311 and the traction groove B3321 again. At this time, the guide member 321 is locked in the converging position / the separating position again.

[0043] Secondly: not shown in the drawings, the length direction of the traction groove A3311 is parallel to the moving direction of the support plate 310, and the length direction of the traction groove B3321 intersects with the length direction of the traction groove A3311. In this setting, the traction groove A3311 and the traction groove B3321 always have an overlapping hole position for the guide member 321 to pass through, and this overlapping hole position will move towards the converging position / the separating position when the dial B332 moves. When the bearing bar 320 is in the converging position / the separating position, under the action of the separating drive 340, one end of the traction groove A3311 and the side wall of the traction groove B3321 abut against the guide member 321 in opposite directions. That is to say, the traction groove A3311 and the traction groove B3321 respectively provide a force to the guide member 321, and the directions of these two forces are generally opposite, clamping and fixing the guide member 321. Thus, the position of the bearing bar 320 in the converging position and the separating position is ensured to be fixed; when the bearing bar 320 moves from the converging position to the separating position / from the separating position to the converging position, the separating drive 340 drives the dial B332 to move, and thus the above-mentioned overlapping position continuously changes. The guide member 321 moves away from one end of the traction groove A3311 and moves with the overlapping position. When the guide member 321 reaches the other end of the traction groove A3311, the other end of the traction groove A3311 and the side wall of the traction groove B3321 abut against the guide member 321 in opposite directions to clamp and fix the guide member 321. Thus, the position of the bearing bar 320 in the converging position and the separating position is ensured to be fixed. Obviously, in this setting, when the bearing bar 320 is in the converging position / the separating position, the guide member 321 abuts against the top end of the traction groove A3311, but does not necessarily abut against the top end of the traction groove B3321.

[0044] In addition, it should be noted that when assembling the positions, when the traction groove A3311 and the traction groove B3321 cooperate to fix the guide member 321, the gap width between adjacent load-bearing bars 320 is preferably set in the range of 1.5 mm - 2.5 mm. Of course, the specific width can be selected and set according to the thickness of the cutting tool.

[0045] In this embodiment, the series-connected film platform can cooperate to complete the cutting of the whole film and the short-range distance separation action, simplify the equipment structure, reduce the equipment manufacturing cost, and optimize the film pasting production process. When the film strip is separated at a short range, by locking the load-bearing bar 320, the position dimension accuracy of the film strip is ensured, and further the position dimension accuracy of the subsequent film pasting is ensured. The overall transfer and distance separation of the distance separation component 300 are two independent actions. The moving direction of the distance separation component 300 is the same as the moving direction of the dial plate B332. During specific operation, the two can be carried out simultaneously, thereby improving the work efficiency.

[0046] Embodiment Two

[0047] In this embodiment, the second film strip transfer method is adopted, that is, the method of transferring the series-connected film strip from the cutting position to the grasping position of the transfer device.

[0048] As Figures 4-6 shown, a series-connected film platform includes a base 100 and a distance separation component 300. The distance separation component 300 is installed on the base 100.

[0049] Among them, the distance separation component 300 includes a support plate 310, load-bearing bars 320, a dial plate C333, and a distance separation drive 340. The load-bearing bars 320 are installed on the support plate 310 through linear guide rails 350. The dial plate C333 is arranged between the support plate 310 and the load-bearing bars 320. Specifically, the dial plate C333 is movably arranged on the support plate 310. A traction groove C3331 is provided on the dial plate C333, and a guide member 321 passing through the traction groove C3331 is provided on the load-bearing bar 320. When the load-bearing bar 320 is at the assembly position / distance separation position, one top end of the traction groove C3331 abuts against the guide member 321. During operation, the dial plate C333 is driven to move by the distance separation drive 340, and the dial plate C333 drives the guide member 321 to move through the traction groove C3331, realizing the position conversion of the load-bearing bar 320 between the assembly position and the distance separation position.

[0050] Meanwhile, the spacing component 300 further includes a transfer drive 200. The transfer drive 200 is installed on the base 100, and the output end of the transfer drive 200 is connected to the support plate 310. The transfer drive 200 can drive the support plate 310 to move relative to the base 100, so as to realize the position conversion of the spacing component 300 between the film cutting position and the film taking position. By increasing the structural strength of the base 100, the stability of the spacing component 300 during the position conversion process can be ensured.

[0051] To better understand the solution in this embodiment, the following details the specific process of the spacing action of the carrier bar 320.

[0052] In this embodiment, as Figure 6 shown, the carrier bar 320 moves along the extension direction of the linear guide 350. The length direction of the traction groove C3331 intersects with the moving direction of the carrier bar 320. At the same time, the moving direction of the dial C333 is consistent with the length direction of the carrier bar 320. In this way, when the carrier bar 320 is at the converging position / spacing position, one end of the traction groove C3331 abuts against the guide member 321. While the guide member 321 is subjected to the abutting force of the traction groove C3331, under the action of the linear guide 350, the guide member 321 is locked. Thus, the position of the carrier bar 320 at the converging position and the spacing position is fixed. When the carrier bar 320 moves from the converging position to the spacing position / from the spacing position to the converging position, the spacing drive 340 drives the dial C333 to move, and the guide member 321 changes from the locked state to the relaxed state. During the movement of the dial C333, the side wall of the dial C333 acts on the guide member 321, causing the guide member 321 to move along the length direction of the dial C333. When the guide member 321 abuts against the other end of the dial C333, the guide member 321 is re-locked at the converging position / spacing position.

[0053] As a further improvement, as Figure 6 shown, buffer grooves 3332 are provided at both ends of the traction groove C3331. The extension direction of the buffer grooves 3332 is parallel to the length direction of the carrier bar 320. By providing the buffer grooves 3332, when the guide member 321 is locked at the converging position / spacing position, the force of the dial C333 acting on the guide member 321 is always perpendicular to the force of the linear guide 350, achieving a better locking effect on the guide member 321.

[0054] In this embodiment, the string indirect film platform can cooperate to complete the cutting and short-distance separation actions of the entire film, simplify the equipment structure, reduce the equipment manufacturing cost, and optimize the film pasting production process. When the film strips are separated at a short distance, by locking the bearing strip 320, the position dimension accuracy of the film strips is guaranteed, and further the position dimension accuracy of the subsequent film pasting is ensured. The overall transfer and separation of the separation assembly 300 are two independent actions, and in specific operations, the two can be carried out simultaneously, thereby improving the work efficiency. At the same time, the moving direction of the separation assembly 300 is perpendicular to the moving direction of the dial C333. Compared with the first embodiment, the dial C333 can be hidden under the bearing strip 320 to optimize the appearance of the equipment.

[0055] In the above-mentioned first embodiment and second embodiment, two or more guiding members 321 are provided on the same bearing strip 320. Of course, the number of corresponding dials and traction grooves is also adjusted accordingly, so that the guiding members 321 perform moving actions with consistent trajectories in different traction grooves. By providing two or more guiding members 321, dials and traction grooves, the bearing strip 320 at the converging position / separating position can be better locked, and the inclination of the bearing strip 320 caused by the gaps at the positions where its two ends are movably connected to the support plate 310 can be avoided.

[0056] In addition, in the second embodiment, as Figure 5 shown, the dial can be set to one piece. When set to one piece, two sets of parallel traction grooves C3331 are provided on the dial, and two guiding members 321 are provided on the same bearing strip 320. The two sets of traction grooves C3331 are in a translation array relationship; of course, the dial can be set to two pieces, not shown in the figure. The two dials are arranged in a mirror image, and the approaching and separating actions of the two dials are realized through a bidirectional lead screw. The above-described dial setting method is an exemplary illustration for easy understanding and should not be construed as a limitation to the present application.

[0057] In the present application, as Figure 1 or Figure 4 shown, an adsorption structure 322 is provided on the upper end surface of the bearing strip 320. Through the adsorption structure 322, the film strips can be fixed on the upper end surface of the bearing strip 320, and the position change of the film strips during the transfer and separation of the bearing strip 320 can be avoided. Here, the adsorption structure 322 can be an adsorption hole directly opened on the bearing strip 320, or a rubber suction head or other adsorption structures 322 embedded and installed on the upper end surface of the bearing strip 320. The present utility model does not make specific limitations thereto.

[0058] In addition, in the present application, the width of the carrier strip 320 is between 8 mm and 38 mm to meet the requirements for different widths of the film strips. For example, when it is necessary to cut film strips with widths of 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, and 40 mm, the spacing between the respective carrier strips 320 is set at 2 mm, and the widths of the corresponding carrier strips 320 are set at 8 mm, 13 mm, 18 mm, 23 mm, 28 mm, 33 mm, and 38 mm respectively. Of course, the above dimensions are only exemplary descriptions of the requirements for setting some of the carrier strips 320, and specific settings can be made according to actual needs, and the present utility model does not make specific limitations thereto.

[0059] In the present application, since the width of the carrier strip 320 is small and the quantity is large, when connecting the carrier strip 320 and the support plate 310, multiple sets of parallel linear guides 350 can be provided. At the same time, as Figure 7 shown, the carrier strip 320 is provided with a relief groove 323 for relieving the slider of other linear guides 350. In this way, it can be ensured that the carrier strip 320 can maintain a small spacing at the converging position, which is convenient for the cutting tool to complete the cutting of the whole film. At the same time, a linear guide 350 with high structural strength can be selected to avoid deformation of the linear guide 350 during use.

[0060] Embodiment III

[0061] In this embodiment, the first film strip transfer method is adopted, that is, the cutting tool is removed and the transfer device is moved in.

[0062] In this embodiment, the position conversion function of the distance separating component 300 on the intermediate film connecting platform in Embodiment I and Embodiment II from the film cutting position and the film taking position is cancelled. The transfer device grabs and transfers the film strip by removing the cutting tool and moving in the transfer device. Of course, in this embodiment, the short-range distance separation of the carrier strip 320 is still adopted to ensure that the transfer device can effectively grab the film strip and ensure the dimensional accuracy of the film strip.

[0063] Specifically, the intermediate film connecting platform provided in this embodiment includes a base 100 and a distance separating component 300. The distance separating component 300 is installed on the base 100. Among them, the distance separating component 300 includes a support plate 310, a plurality of carrier strips 320, a distance separating traction member, and a distance separating drive 340. The carrier strip 320 is movably arranged on the support plate 310. The distance separating traction member is arranged between the support plate 310 and the carrier strip 320. The distance separating drive 340 is used to drive the distance separating traction member to act so as to drive the carrier strip 320 to perform converging / distance separating actions. In this embodiment, the short-range distance separation method of the carrier strip 320 can adopt the short-range distance separation method in Embodiment I or the short-range distance separation method in Embodiment II, and the present embodiment does not elaborate on its structure. In addition, the structure of the intermediate film connecting platform in this embodiment is not separately shown in the drawings.

[0064] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
