[0057] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0058] The light receiving part in a solar cell module is the upper surface of the cell piece. In order to achieve the maximum light receiving area in a limited area, the adjacent cell pieces are overlapped in the existing photovoltaic cell, but this will cause the solder strip to have too much stress on the edge of the cell piece, and the edge of the cell piece is easy to crack or break. In order to solve the above-mentioned problems, a film strip is currently placed between the overlapping parts of adjacent cell pieces, and the film strip is used to buffer the stress of the solder strip on the edge of the cell piece.

[0059] The raw material of the film strip is a film roll, which needs to be first cut into film pieces, and then the film pieces are cut into multiple film strips, and then the film strips are sequentially sent to the cell string stringing equipment. Therefore, in order to match the automatic production of the cell string stringing equipment, a film strip slitting and carrying device for automatically slitting the film pieces into film strips and conveying to the cell string stringing equipment is needed.

[0060] Therefore, the present application provides a film strip slitting and carrying device, please refer to Figures 1 to 4As shown, the film strip cutting and conveying device provided by the embodiment of the application comprises a conveying mechanism 10 and a transfer mechanism 20. The conveying mechanism 10 comprises a first driving part 11 and an execution part 12. The driving end of the first driving part 11 is connected to the execution part 12. The execution part 12 is at least configured to pick up or release a film sheet 30 to be cut. The execution part 12 is further configured to cut the picked-up film sheet 30 to be cut into a plurality of film strips. The first driving part 11 is configured to drive the execution part 12 to move between a material taking station 31 and a cutting station 32, so as to pick up the film sheet 30 to be cut at the material taking station 31 by the execution part 12 and convey the picked-up film sheet 30 to be cut to the cutting station 32. The transfer mechanism 20 comprises a second driving part 21 and a transfer platform 22. The driving end of the second driving part 21 is connected to the transfer platform 22. The second driving part 21 is configured to drive the transfer platform 22 to move to the cutting station 32, so as to receive the film sheet 30 conveyed by the execution part 12 by the transfer platform 22. The second driving part 21 is further configured to drive the transfer platform 22 and the plurality of film strips cut by the execution part 12 to move to a material feeding station 33, so as to be picked up by a battery string stringing device on the transfer platform 22.

[0061] The film strip cutting and conveying device provided by the embodiment of the application realizes automatic cutting of the film sheet 30 into a plurality of film strips and conveying of the cut film strips to the material feeding station 33, so as to be picked up by the battery string stringing device, and has high work efficiency. Moreover, the execution part 12 has the functions of picking up and cutting, which simplifies the action process of cutting and conveying of the film sheet 30, improves the cutting and conveying efficiency of the film sheet 30, and meets the fast-paced operation requirements.

[0062] As an implementation manner, the execution part 12 comprises a support 13, a cutting assembly 14 and an adsorption plate 15. The driving end of the first driving part 11 is connected to the support 13. The cutting assembly 14 comprises a base 140, a driving assembly 141, a knife seat 142 and a plurality of blades 143. The base 140 is fixedly installed on the support 13. The knife seat 142 is slidingly installed on the base 140. The plurality of blades 143 are installed on the knife seat 142 at intervals. The driving end of the driving assembly 141 is connected to the knife seat 142. The driving assembly 141 is at least configured to drive the knife seat 142 to reciprocally move in a horizontal direction, so as to cut the film sheet 30 picked up by the execution part 12 into a plurality of film strips. The adsorption plate 15 is installed below the base 140. A plurality of avoiding holes 150 penetrating through the adsorption plate 15 are arranged on the adsorption plate 15 at intervals. Each avoiding hole 150 is provided corresponding to one blade 143. Each blade 143 penetrates through the corresponding avoiding hole 150. The length of the avoiding hole 150 is greater than the length of the film strip. A plurality of first adsorption holes (not shown in the figure) for adsorbing the film sheet 30 to be cut are arranged on the adsorption plate 15.

[0063] Specifically, the adsorption plate 15 is provided with an adsorption cavity, a plurality of first adsorption holes are communicated with a first end of the adsorption cavity, and a second end of the adsorption cavity is communicated with the air pump. The air in the adsorption cavity is extracted by the air pump, so that a negative pressure for adsorbing the film sheet 30 to be slitting is formed at the first adsorption hole.

[0064] Specifically, the knife seat 142 is movably assembled on the base 140 in the horizontal direction through a sliding guide pair composed of a linear guide rail and a sliding block.

[0065] It can be seen that through the cooperation of the base 140, the driving assembly 141, the knife seat 142 and the plurality of blades 143, the film sheet 30 picked up by the execution part 12 is one-time slitted into a plurality of film strips, thereby providing a slitting assembly 14 with high slitting efficiency and good slitting effect. By integrating the adsorption plate 15 below the base 140 and providing a plurality of avoiding holes 150 and a plurality of first adsorption holes on the adsorption plate 15, the adsorption and release of the film sheet 30 are realized without affecting the slitting of the film sheet 30, and the overall structure is simple, compact, high integration and ingenious design.

[0066] Please refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As an embodiment, the execution part 12 is also configured to cooperate with the transfer platform 22 at the slitting station 32 to slit the film sheet 30 to be slitted into a plurality of film strips, and a plurality of avoiding grooves 220 are arranged on the transfer platform 22 at intervals, each avoiding groove 220 corresponding to a blade 143. When the execution part 12 is slitting the film sheet 30, the adsorption plate 15 is pressed against the transfer platform 22, and the plurality of blades 143 pass through the corresponding avoiding holes 150 and extend into the corresponding avoiding grooves 220.

[0067] Specifically, the slitting station 32 is provided with a waste box 40 located below the transfer platform 22, and the waste box 40 is configured to receive the unqualified film sheet 30 adsorbed by the adsorption plate 15.

[0068] The general process of the execution part 12 cooperating with the transfer platform 22 at the slitting station 32 to slit the film sheet 30 to be slitted is as follows: the first driving part 11 drives the adsorption plate 15 to press the adsorbed film sheet 30 to be slitted on the transfer platform 22, so that the plurality of blades 143 pass through the corresponding avoiding holes 150 and extend into the corresponding avoiding grooves 220; then the driving assembly 141 drives the knife seat 142 to move in the horizontal direction, thereby driving the plurality of blades 143 to one-time slit the film sheet.

[0069] Of course, it needs to be explained that the execution part 12 can also cut the film 30 adsorbed on the adsorption plate 15 alone, the knife holder 142 is connected with a driving member, the driving member drives the knife holder 142 to move close to the adsorption plate 15, so that the several blades 143 pierce the film 30 adsorbed on the adsorption plate 15 after passing through the corresponding avoiding hole 150, and then the driving assembly 141 drives the knife holder 142 to move horizontally to cut the film 30 adsorbed on the adsorption plate 15.

[0070] It can be seen that by arranging several avoiding grooves 220 on the transfer platform 22 and by cooperation of the execution part 12 and the transfer platform 22, the film 30 adsorbed on the adsorption plate 15 is directly cut by the blade 143 after being pressed and positioned on the transfer platform 22, without the need to configure a pressing mechanism on the transfer platform 22, which is simple in structure and low in cost; further simplifies the process of film cutting, improves the cutting efficiency and cutting precision of the film.

[0071] Please refer to Figure 7 As an embodiment, the transfer platform 22 is provided with several load-bearing members 221 extending along the length direction of the film strip at intervals, each load-bearing member 221 is configured to carry a film strip, and an avoiding groove 220 is formed between adjacent two load-bearing members 221, and a plurality of second adsorption holes 222 for adsorbing the film strip are arranged on the carrying surface of each load-bearing member 221.

[0072] Specifically, the transfer platform 22 is provided with several air flow channels, each air flow channel corresponds to a load-bearing member 221, the first end of the air flow channel is in communication with all the second adsorption holes 222 on the corresponding load-bearing member 221, and the second end of the air flow channel is provided with an air connector 223, the air connector 223 is connected with an air pump, and each air connector 223 can be controlled to be connected or disconnected with air; the air pump is configured to suck air in the corresponding air flow channel through the air connector 223, so as to adsorb and fix the film strip on the corresponding load-bearing member 221 through the second adsorption hole; the air pump is also configured to blow gas into the air flow channel through the air connector 223, so as to blow the film strip on the corresponding load-bearing member 221 away from the carrying surface of the load-bearing member 221 through the second adsorption hole 222, so as to facilitate the film strip to be picked up by the battery string equipment.

[0073] It can be seen that by arranging several load-bearing members 221 on the transfer platform 22 at intervals and forming an avoiding groove 220 between adjacent two load-bearing members 221, the avoidance of the blade 143 during film cutting and the separate carrying of the cut film strip are realized; meanwhile, the second adsorption hole 222 is arranged on each load-bearing member 221, the adsorption and positioning of each cut film strip are realized, the deviation of the film strip during movement on the transfer platform 22 is avoided, and the carrying precision of the cut film strip is improved.

[0074] Please refer to Figure 9As shown, as an embodiment, the lower surface of the adsorption plate 15 is provided with a flexible gasket 151, and the flexible gasket 151 is provided with openings corresponding to the first adsorption holes and the relief holes 150 on the adsorption plate 15.

[0075] As can be seen, by providing the flexible gasket 151 on the lower surface of the adsorption plate 15 and opening a plurality of openings on the flexible gasket 151, the flexible gasket 151 is pressed and fixed on the transfer platform 22 while avoiding the blade 143, ensuring that the film is tightly pressed, avoiding the film from shifting and shaking during the cutting process; at the same time, it avoids the hard contact between the adsorption plate 15 and the film, which causes the film to be pressed and injured when being pressed, and plays a role in protecting the film.

[0076] Please refer to Figure 1 , Figure 2 As shown, as an embodiment, the first driving part 11 includes a first driving member 110, a rotating seat 111, and a first lifting driving member 112. The driving end of the first driving member 110 is connected to the rotating seat 111, and the first driving member 110 is configured to drive the rotating seat 111 to rotate by a preset angle. The fixed end of the first lifting driving member 112 is installed on the rotating seat 111, and the driving end of the first lifting driving member 112 is connected to the execution part 12. The first lifting driving member 112 is configured to drive the execution part 12 to lift.

[0077] Specifically, the conveying mechanism 10 is arranged on the side of the transfer mechanism 20, the material taking station 31 and the cutting station 32 are perpendicular to each other, the first driving member 110 is configured to drive the rotating seat 111 to rotate by 90°, so as to cooperate with the first lifting driving member 112 to drive the execution part 12 to move between the material taking station 31 and the cutting station 32.

[0078] Specifically, the first driving member 110 adopts a conventional rotating module, and the first lifting driving member 112 adopts a conventional ball screw type linear module.

[0079] As can be seen, through the cooperation of the first driving member 110, the rotating seat 111 and the first lifting driving member 112, the rotation and lifting of the execution part 12 are realized, so as to move the execution part 12 between the material taking station 31 and the cutting station 32, and a first driving part 11 with rotation and lifting functions is provided, which has a simple overall structure, low cost and high work efficiency.

[0080] Please refer to Figure 3 , Figure 4 and Figure 9 As shown, as an embodiment, the adsorption plate 15 and the base 140 are connected by a plurality of elastic members 16, and the elastic members 16 are configured to be elastically deformed in the vertical direction.

[0082] It can be seen that by arranging a plurality of elastic members 16 between the adsorption plate 15 and the base 140, floating connection of the adsorption plate 15 relative to the base 140 is achieved, and when the adsorption plate 15 adsorbs the film sheet 30 or the adsorption plate 15 is pressed downward on the transfer platform 22, the elastic members 16 buffer the pressure received by the adsorption plate 15, thereby avoiding the film sheet 30 being crushed or the adsorption plate 15 being hard connected with related parts.

[0084] Specifically, the first pulley 1411 and the second pulley 1412 are synchronous pulleys, and the first transmission belt 1413 is a synchronous belt.

[0085] It can be seen that through cooperation of the motor 1410, the first pulley 1411, the second pulley 1412 and the first transmission belt 1413, the knife seat 142 is driven to reciprocate along the horizontal direction, thereby providing a drive assembly 141 which has simple structure, high transmission efficiency, precise driving stroke control and is convenient to maintain.

[0086] As an embodiment, the drive assembly 141 further includes a third pulley 1414, a fourth pulley 1415 and a second transmission belt 1416, the third pulley 1414 is coaxially connected with the first pulley 1411, the second transmission belt 1416 is sleeved on the third pulley 1414 and the fourth pulley 1415, the motor 1410 is installed on the base 140, the fourth pulley 1415 is installed on the output shaft of the motor 1410, and the motor 1410 is configured to drive the fourth pulley 1415 to rotate, thereby driving the third pulley 1414 to rotate through the second transmission belt 1416, and further driving the first pulley 1411 to rotate.

[0087] ​Specifically, the motor 1410 is installed on the top surface of the base 140.

[0088] It can be seen that through the cooperation of the motor 1410, the third pulley 1414, the fourth pulley 1415 and the second transmission belt 1416, the rotation of the first pulley 1411 is realized. Moreover, the two sets of transmission belt transmission assemblies are adopted, so that the motor 1410 is integrated on the base 140 and does not exceed the base 140 in the horizontal direction, avoiding the interference between the motor 1410 and the stringer, occupying small space, and the structure is more compact.

[0089] Please refer to Figure 1 , Figure 6 and Figure 8 As an embodiment, the transfer mechanism 20 is provided with two sets, and the two sets of transfer mechanisms 20 are arranged at intervals. The transfer platforms 22 of the two sets of transfer mechanisms 20 are alternately moved to the slitting station 32 and the feeding station 33. When the idle transfer platform 22 above the feeding station 33 moves to the slitting station 32, the transfer platform 22 above the slitting station 32 which adsorbs the slit film strip moves to the feeding station 33.

[0090] The transfer platforms 22 of the two sets of transfer mechanisms 20 have the same cycle moving track and move synchronously. The approximate alternation process of the transfer platforms 22 of the two sets of transfer mechanisms 20 of the embodiment is as follows: when the film strip on the transfer platform 22 at the feeding station 33 is taken, the transfer platform 22 at the slitting station 32 slides to the left to the feeding station 33. In this process, the transfer platform 22 at the feeding station 33 first rises, then slides to the right above the slitting station 32, and then descends to the slitting station 32. Then the carrying mechanism 10 places a new film piece on the transfer platform 22 at the slitting station 32 and performs slitting processing. After the film strip on the transfer platform 22 at the feeding station 33 is taken, the above cycle operation is repeated.

[0091] Figure 8 The dashed arrow in the middle of the drawing is the moving path of the transfer platform 22 at the slitting station 32 to the feeding station 33, Figure 8 The solid arrow in the middle of the drawing is the moving path of the transfer platform 22 at the feeding station 33 to the slitting station 32. Of course, the moving paths of the two transfer platforms 22 can also be opposite to those shown in the drawing, that is, when the film strip on the transfer platform 22 at the feeding station 33 is taken, the transfer platform 22 at the slitting station 32 slides to the right to the feeding station 33. In this process, the transfer platform 22 at the slitting station 32 first rises, then slides to the left above the feeding station 33, and then descends to the feeding station 33.

[0092] It can be seen that by arranging two sets of transfer mechanisms 20 and alternately moving the transfer platforms 22 of the two sets of transfer mechanisms 20 to the slitting station 32 and the feeding station 33, the film strips after slitting are continuously moved to the feeding station 33, the feeding of the film strips is realized without interruption, and the feeding efficiency of the film strips is improved.

The fixed end of the second lifting driving member 212 is installed on the transverse moving seat 211, and the driving end of the second lifting driving member 212 is connected to the transfer platform 22. The second lifting driving member 212 is configured to drive the transfer platform 22 to lift.

[0094] Specifically, the second driving member 210 adopts a conventional synchronous belt type linear module, and the second lifting driving member 212 adopts a driving form of a synchronous belt type linear module cooperating with a ball screw 213. The ball screw 213 is rotatably and vertically installed on the transverse moving seat 211. A screw nut 214 is sleeved on the ball screw 213. The screw nut 214 is fixedly connected to the transfer platform 22. The transfer platform 22 is installed on the transverse moving seat 211 in a sliding guide pair composed of a linear guide rail and a sliding block in a manner of being able to slide up and down.

[0095] It can be seen that by cooperation of the second driving member 210, the transverse moving seat 211, and the second lifting driving member 212, the transfer platform 22 is driven to move transversely and lift, so as to alternately move the transfer platform 22 to the slitting station 32 and the feeding station 33.

[0101] It should be noted that after the cutting assembly 14 cooperates with the transfer platform 22 to cut the film sheet to be cut into a plurality of film strips, the first driving part 11 drives the adsorption plate 15 to move away from the cutting station 32 and to the material taking station 31 to adsorb the next film sheet to be cut.

[0102] It should be noted that the approximate process of the battery string assembly equipment picking up the film strip on the transfer platform 22 in step S4 is that the battery string assembly equipment will take away a group of film strips on the transfer platform 22 each time, and after a group of film strips is taken away, the second driving part 210 drives the horizontal moving seat 211 to horizontally move, drives the transfer platform 22 to move a width distance of a group of film strips close to the battery string assembly equipment, so as to make each group of film strips to be taken to be in the same position each time, and improve the material taking efficiency of the film strip.

[0107] 4) The transfer platform can adsorb and position the cut film strip, avoids the offset of the film strip during the movement of the transfer platform, and improves the carrying precision of the cut film strip;

[0108] 5) The lower surface of the adsorption plate is provided with a flexible gasket, which ensures that the film sheet is tightly pressed, avoids the offset and shaking of the film sheet during the cutting of the film sheet, avoids the pressure injury of the film sheet caused by the hard contact between the adsorption plate and the film sheet during the pressing, and plays a role in protecting the film sheet;
