[0002] In the process of stringing solar cells, the preparation of membrane strips is involved. The existing method for preparing membrane strips involves: pulling out the adhesive film from the film roll, cutting the pulled-out film into strips; using a puller to pull out the strips and then lowering them onto a segmentation and cutting platform; and finally cutting the strips on the platform into segments to obtain membrane strips of the required length. However, after cutting the film into multiple strips, the puller needs to transfer the strips twice: horizontally pulling them out and lowering them for placement. During these two transfers, there is a significant risk of film misalignment, which affects the subsequent segmentation and cutting effect. Therefore, there is an urgent need to develop a membrane strip preparation device to solve the above problems. Summary of the Invention

Detailed Implementation

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 8 As shown, a film strip preparation device includes a feeding device 1, a first cutting device 2, a spacing device 3, a segmented receiving device 4, and a second cutting device 5. The feeding device 1 supplies adhesive film; the first cutting device 2 cuts the sheet adhesive film supplied by the feeding device 1 into multiple strip adhesive films; the spacing device 3 adjusts the spacing of each strip adhesive film after cutting; the segmented receiving device 4 receives and adheres to each strip adhesive film after the spacing adjustment, and moves each strip adhesive film forward by a preset length; the second cutting device 5 cuts each strip adhesive film on the segmented receiving device 4 into segments.

[0031] Specifically, in this embodiment, the feeding device 1 includes a mounting plate 11, a material roll shaft 12 for mounting the adhesive film roll, a rotatably mounted drive roller 13, and a drive component for driving the drive roller 13 to rotate. The drive roller 13 is located on the side of the first cutting device 2 away from the material roll shaft 12. The outer periphery of the drive roller 13 has a plurality of first annular grooves axially formed, and each annular groove has an adsorption hole for vacuum adsorption and fixing the strip-shaped adhesive film. The drive component is preferably a motor.

[0032] It should be noted that the mounting plate 11 can be configured to move axially along the material roll shaft 12, so that when the sheet film deviates, the mounting plate 11 can move axially along the material roll shaft 12 to drive the film roll on the material roll shaft 12 to move, thereby achieving film correction and ensuring film cutting accuracy.

[0033] In this embodiment, the first cutting device 2 is mounted on the mounting bracket 10. For example... Figure 2As shown, the first cutting device 2 includes two cooperating cutting rollers 21. The first cutting roller 21 has a plurality of annular blades 211 spaced apart along the axial direction, and the second cutting roller 21 has a plurality of second annular grooves 212 spaced apart along the axial direction, wherein one annular blade 211 is located within one second annular groove 212. The first cutting roller 21 is connected to a driving assembly for driving its rotation. In this embodiment, the driving assembly can be a motor-driven belt drive assembly or a gear drive assembly to drive the rotation of the first cutting roller 21, or it can be a motor that directly drives the first cutting roller 21 to rotate.

[0034] In this embodiment, the spacing device 3 is mounted on the mounting frame 10 and includes a plurality of spacing brushes 31 and a plurality of spacing rollers 32; wherein, as shown in the figure... Figure 3 and 4 As shown, a plurality of brush rods 311 are arranged side by side at equal intervals on the spacing brush 31; a plurality of third annular grooves 321 are equally spaced along the axial direction on the spacing roller 32; the distance between two adjacent brush rods 311 is the same as the distance between two adjacent third annular grooves 321. Preferably, each spacing brush 31 is positioned close to the drive roller 13. In use, each strip of adhesive film output from the drive roller 13 first passes through each spacing brush 31 in sequence, and then passes through each spacing roller 32 in sequence, thereby completing the spacing adjustment.

[0035] In this embodiment, as Figure 5-7 As shown, the segmented receiving device 4 includes a synchronous belt 41 that rotates in a circular motion and several receiving plate platforms 42 that are equidistantly fixed on the synchronous belt 41. Limiting plates 43 are provided on both sides of the synchronous belt 41, and a driving wheel 46 and a driven wheel 47 are rotatably mounted at both ends of these limiting plates 43, respectively. The driving wheel 46 is connected to a drive motor 48 that drives its rotation. The synchronous belt 41 drives the driving wheel 46 and the driven wheel 47. Several adsorption holes are provided on the receiving plate platforms 42 for vacuum adsorption and fixing of the strip-shaped adhesive films after spacing adjustment. Preferably, several protrusions are spaced apart on the receiving plate platforms 42, and each protrusion has a placement groove for positioning and placing the strip-shaped adhesive films; each adsorption hole is distributed within a placement groove.

[0036] In use, at least one receiving plate platform 42 located at one end of the upper section of the synchronous belt 41 is vacuum-adsorbed and fixed to each strip of adhesive film; under the drive of the drive motor 48 and the transmission action of the drive wheel 46 and the driven wheel 47, the synchronous belt 41 drives each receiving plate platform 42 to move together, thereby realizing the horizontal pulling of each strip of adhesive film after the spacing adjustment to a preset length.

[0037] In this segmented receiving device 4, the receiving plate platform 42 has one or more positioning grooves 421 arranged at intervals along the vertical conveying direction. Multiple rows of positioning blocks 6 are arranged within each positioning groove 421, and each positioning block 6 is connected to the synchronous belt 41. The receiving plate platform 42 is connected to one row of positioning blocks 6. This structure allows the receiving plate platform 42 to smoothly pass through the arc-shaped section along with the synchronous belt 41.

[0038] Furthermore, a partition 7 is provided between two adjacent receiving plate platforms 42, and buffer blocks 8 are provided on both sides of the partition 7 to prevent rigid collisions between the two receiving plate platforms 42.

[0039] In the segmented receiving device 4, the side of the limiting plate 43 facing the synchronous belt 41 is provided with an upper limit horizontal groove 431, which corresponds to the upper horizontal section of the synchronous belt 41; the bottom of the receiving plate platform 42 is provided with two sets of limiting pulleys 44, which can slide into the corresponding upper limit horizontal groove 431 and move forward.

[0040] In use, the movement accuracy of each strip of adhesive film can be ensured by the rolling of each limiting pulley 44 along the corresponding upper limit horizontal groove 431; in addition, it can prevent the receiving plate platform 42 from floating up and down during the segmented cutting of the strip of adhesive film, thus affecting the cutting effect.

[0041] Furthermore, a lower limit horizontal groove 432 is provided on the side of the limiting plate 43 facing the synchronous belt 41, which corresponds to the lower horizontal section of the synchronous belt 41; the two sets of limiting pulleys 44 can slide into the corresponding lower limit horizontal groove 432 and move forward to ensure the movement accuracy of each receiving plate platform 42.

[0042] In this embodiment, a plurality of limiting components 45 are provided on the opposite sides of the two limiting plates 43. Each limiting component 45 includes a limiting block and a lifting drive for driving the limiting block to move up and down. The lifting drive can drive the corresponding limiting block to move upward between two adjacent receiving plate platforms 42. Preferably, the lifting drive is a lifting cylinder.

[0043] In use, driven by the lifting drive, the limiting block moves upward to between two adjacent receiving plate platforms 42 to limit the receiving plate platform 42 located behind, thereby preventing the receiving plate platform 42 from moving during the segmented cutting of strip adhesive film and affecting the cutting effect.

[0044] In this embodiment, the second cutting device 5 is positioned close to the segmented receiving device 4 and includes one or more cutting mechanisms arranged side-by-side at intervals. For example... Figure 8As shown, the cutting mechanism includes a cutting blade 51 connected to a cutting blade drive assembly 52 that drives it downwards to between two adjacent receiving plate platforms 42. Several pressing assemblies 53 for fixing each strip of adhesive film are distributed on both sides of the cutting blade 51. Each pressing assembly 53 includes a pressing head seat and several pressing heads arranged side-by-side at intervals on the pressing head seat. Each pressing head presses and fixes one strip of adhesive film. A spring is provided between the pressing head and the pressing head seat, and a guide rod is provided inside the spring. One end of the guide rod is fixedly connected to the pressing head, and the other end is movably mounted on the pressing head seat. The cutting blade drive assembly 52 is preferably a cylinder.

[0045] In use, driven by the cutting blade drive assembly 52, the cutting blade 51 and the two pressing assemblies 53 move downwards together; each pressing head contacts the strip-shaped adhesive film located on the two adjacent receiving plate platforms 42; as they continue to move downwards, the springs are compressed and act on the corresponding pressing heads, causing each pressing head to press and fix the corresponding strip-shaped adhesive film, while the cutting blade 51 enters between the two receiving plate platforms 42, thereby completing the segmented cutting of each strip-shaped adhesive film. After segmented cutting, at least one receiving plate platform 42 still retains the adhesive film in place to ensure uninterrupted pulling out of the strip-shaped adhesive film.

[0046] It should be noted that the cutting blade drive assembly 52 can also achieve segmented cutting by driving the cutting blade 51 to rotate and move downward.

[0047] This invention discloses a membrane strip preparation device. In use, a feeding device 1 supplies adhesive film; a first cutting device 2 cuts the sheet adhesive film supplied by the feeding device 1 into several strip-shaped adhesive films; a spacing device 3 adjusts the spacing of each strip-shaped adhesive film; a receiving plate platform 42 of a segmented receiving device 4 receives and adsorbs the strip-shaped adhesive films after the spacing adjustment, and through the cyclic movement of the receiving plate platform 42, moves each strip-shaped adhesive film forward by a preset length; a second cutting device 5 cuts each strip-shaped adhesive film on the segmented receiving device 4 into segments, thereby obtaining one or more sets of membrane strips of the required length. Compared with existing membrane strip preparation equipment, the membrane strip preparation equipment of this application reduces the number of transfers of the strip-shaped adhesive films, reduces the risk of displacement of the strip-shaped adhesive films during the transfer process, and improves the accuracy of membrane strip preparation. In addition, after segmented cutting, at least one receiving plate platform 42 still maintains adsorption and fixation of each strip-shaped adhesive film, thereby ensuring uninterrupted pulling out of the strip-shaped adhesive films and improving the efficiency of membrane strip preparation.
