Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and in particular to a circulating conveyor line. Background Technology

[0002] The fabrication of membrane strips is a crucial step in the stringing process of solar cells. The existing method involves: pulling out the adhesive film from the film roll, dividing the pulled-out film into strips; using a puller to draw out the strips and then lowering them onto a segmentation and cutting platform; finally, cutting the strips on the platform into segments to obtain the desired length. However, after placing the strips on the cutting platform, the puller needs to be moved back to draw them out again, thus affecting the fabrication efficiency. Summary of the Invention

[0003] The purpose of this invention is to propose a circulating conveyor line that can continuously pull out the adhesive film, thereby improving the efficiency of film strip preparation.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A circulating conveyor line includes a conveyor line body and several receiving plate platforms;

[0006] The conveyor body includes a frame, a drive wheel and a driven wheel rotatably disposed at both ends of the frame, a synchronous belt, and a drive motor that drives the drive wheel to rotate. The drive wheel and the driven wheel are connected by the synchronous belt.

[0007] Each of the receiving plate platforms is fixed side by side at intervals on the synchronous belt, and the receiving plate platform has a number of adsorption holes on the side away from the synchronous belt for vacuum adsorption and fixing of the adhesive film.

[0008] Furthermore, the frame includes two limiting plates disposed on both sides of the timing belt, and an upper limit horizontal groove is provided on the side of the limiting plate facing the timing belt, the upper limit horizontal groove being provided corresponding to the upper horizontal section of the timing belt;

[0009] A plurality of connecting blocks are provided between the timing belt and the limiting plate. The connecting blocks are connected to the corresponding receiving plate platform, and limiting pulleys are installed on the connecting blocks. The limiting pulleys can enter the upper limit horizontal groove and move along the upper limit horizontal groove.

[0010] Furthermore, a lower limiting horizontal groove is provided on the side of the limiting plate facing the synchronous belt. The lower limiting horizontal groove is located below the upper limiting horizontal groove and corresponds to the lower horizontal section of the synchronous belt. The limiting pulley can enter the lower limiting horizontal groove and move along the lower limiting horizontal groove.

[0011] Furthermore, the receiving plate platform has a connecting groove for installing the connecting block.

[0012] Furthermore, the receiving plate platform has one or more positioning grooves spaced apart along the vertical conveying direction, and multiple rows of positioning blocks are arranged in the positioning grooves, each of the positioning blocks being connected to the synchronous belt; the receiving plate platform is connected to one of the rows of positioning blocks.

[0013] Furthermore, each of the positioning grooves is symmetrically arranged relative to the longitudinal center plane of the receiving plate platform.

[0014] Furthermore, the positioning groove is flared.

[0015] Furthermore, a partition is provided between two adjacent receiving plate platforms, and buffer blocks are provided on both sides of the partition.

[0016] Furthermore, several limiting components are provided on both sides of the frame. Each limiting component includes a limiting block and a lifting drive component that drives the limiting block to move up and down. The lifting drive component can drive the corresponding limiting block to move upward between two adjacent receiving plate platforms.

[0017] Furthermore, the receiving plate platform has a plurality of protrusions spaced apart along the vertical conveying direction on the side opposite to the synchronous belt, and the top surface of the protrusions has a placement groove for placing the adhesive film; each of the adsorption holes is distributed in each of the placement grooves.

[0018] The beneficial effects of this utility model are as follows: The circulating conveyor line of this utility model utilizes at least one receiving plate platform to adsorb and fix multiple adhesive films to be cut into segments. Under the drive of the drive motor and the transmission action of the drive wheel and the driven wheel, the synchronous belt drives each receiving plate platform to move together, thereby pulling each adhesive film out of a preset length. After the adhesive film is cut into segments, at least one receiving plate platform still maintains adsorption and fixation of the adhesive film, so as to achieve uninterrupted pulling out of the adhesive film, thereby improving the efficiency of film strip preparation.

Detailed Implementation

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 5 As shown, a circulating conveyor line includes several receiving plate platforms 3 and a conveyor line body that drives each receiving plate platform 3 to circulate together.

[0027] Specifically, in this embodiment, the conveyor line body includes a frame 1, a drive wheel 21 and a driven wheel 22 rotatably disposed at both ends of the frame 1, a synchronous belt 23, and a drive motor 24 for driving the drive wheel 21 to rotate. The drive wheel 21 and the driven wheel 22 are connected by transmission through the synchronous belt 23. Each receiving plate platform 3 is fixed side by side at intervals on the synchronous belt 23, and the receiving plate platform 3 has a plurality of adsorption holes 35 for vacuum adsorption and fixing of the adhesive film on the side away from the synchronous belt 23.

[0028] In this embodiment, the receiving plate platform 3 is provided with a plurality of protrusions 33 at intervals along the vertical conveying direction on the side opposite to the synchronous belt 23. The top surface of the protrusions 33 is provided with a placement groove 34 for placing the adhesive film; each adsorption hole 35 is distributed in each placement groove 34.

[0029] In this embodiment, the frame 1 includes two limiting plates 11 disposed on both sides of the synchronous belt 23. The limiting plate 11 has an upper limit horizontal groove 111 on the side facing the synchronous belt 23, corresponding to the upper horizontal section of the synchronous belt 23. A plurality of connecting blocks 4 are disposed between the synchronous belt 23 and the limiting plates 11. Each connecting block 4 is connected to the receiving plate platform 3 located above it, and a set of limiting pulleys 41 are installed on the connecting blocks 4. Each limiting pulley 41 can enter the upper limit horizontal groove 111 and move along the upper limit horizontal groove 111.

[0030] The precise conveying of each adhesive film is ensured by the rolling of each limiting pulley 41 along the corresponding upper limit horizontal groove 111. In addition, it can prevent the receiving plate platform 3 from floating up and down during the segmented cutting of the adhesive film, thus affecting the cutting accuracy of the adhesive film.

[0031] Furthermore, a lower limit horizontal groove 112 is provided on the side of the limiting plate 11 facing the synchronous belt 23. The lower limit horizontal groove 112 is located below the upper limit horizontal groove 111 and is correspondingly provided with the lower horizontal section of the synchronous belt 23. Each limiting pulley 41 can enter the lower limit horizontal groove 112 and move along the lower limit horizontal groove 112.

[0032] The receiving plate platform 3 is provided with a connecting groove 31 for installing the connecting block 4 to ensure the installation accuracy of the connecting block 4.

[0033] In this embodiment, the receiving plate platform 3 has one or more positioning grooves 32 spaced apart along the vertical conveying direction. Multiple rows of positioning blocks 5 are arranged within each positioning groove 32, and each positioning block 5 is connected to the synchronous belt 23. The receiving plate platform 3 is connected to one row of positioning blocks 5. This structure allows the receiving plate platform 3 to smoothly pass through the arc-shaped section along with the synchronous belt 23.

[0034] Furthermore, the positioning groove 32 is flared to facilitate the smooth entry and exit of the positioning block 5. Each positioning groove 32 is symmetrically arranged with respect to the longitudinal center plane of the receiving plate platform 3. Preferably, in this embodiment, two positioning grooves 32 are provided on the receiving plate platform 3.

[0035] In this embodiment, a partition 6 is provided between two adjacent receiving plate platforms 3. Furthermore, buffer blocks 7 are provided on both sides of the partition 6 to prevent rigid collisions between the two receiving plate platforms 3.

[0036] In this embodiment, several limiting components 8 are provided on both sides of the frame 1. Each limiting component 8 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 3. Preferably, the lifting drive is a lifting cylinder.

[0037] In use, driven by the lifting drive, the limiting block moves upward between two adjacent receiving plate platforms 3 to limit the receiving plate platform 3 located behind, thereby preventing the receiving plate platform 3 from moving during the segmented cutting of the film and affecting the film cutting effect.

[0038] In this utility model, a circulating conveyor line is used in which the ends of each adhesive film are adsorbed and fixed on the receiving plate platform 3. Under the drive of the drive motor 24 and the transmission of the drive wheel 21 and the driven wheel 22, the synchronous belt 23 drives each receiving plate platform 3 to move together, thereby pulling each adhesive film out of the preset length. After the adhesive film is cut into segments, at least one receiving plate platform 3 still holds the adhesive film adsorbed and fixed to ensure that the adhesive film is pulled out continuously, thereby improving the efficiency of film strip preparation.

[0039] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
