Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of photovoltaic cell production equipment, and particularly relates to an alternating conveying mechanism. BACKGROUND

[0002] The light receiving part in a solar cell module is the upper surface of a cell sheet. In order to achieve the maximum light receiving area in a limited area, adjacent cell sheets are arranged in an overlapping manner in the existing photovoltaic cell, but this may cause excessive stress on the cell sheet edge due to the solder strip, and the cell sheet edge is prone to hidden cracks or breakage. In order to solve the above problems, a film strip is placed between the overlapping parts of adjacent cell sheets, and the film strip is used to buffer the stress on the cell sheet edge caused by the solder strip.

[0003] At present, the film strip conveying mechanism is generally used to receive a plurality of film strips produced by a film strip processing device at a receiving station, and then send the plurality of film strips to a feeding station, and wait for a cell string group string device to take away the plurality of film strips at the feeding station. In order to improve the production efficiency, the existing film strip conveying mechanism usually adopts two sets of conveying assemblies working alternately, each set of conveying assembly includes a driving member and a conveying platform, and the driving members of the two sets of conveying assemblies drive the corresponding conveying platforms to move alternately to the receiving station and the feeding station.

[0004] However, the positions of the two conveying platforms at the receiving station and the feeding station are the same. When the first conveying platform is at the receiving station, the second conveying platform moves from the feeding station to the receiving station, and the first conveying platform needs to leave the receiving station and avoid the moving path of the second conveying platform. Therefore, the driving member of each set of conveying assembly includes a horizontal driving module and a vertical driving module, the horizontal driving module can drive the conveying platform to slide horizontally, and the vertical driving module can drive the conveying platform to lift vertically. The driving member first lifts the conveying platform from the receiving station to a certain height, then the driving member drives the conveying platform to slide horizontally to above the feeding station, and then the driving member drives the conveying platform to descend to the feeding station, so as to realize the staggered movement of the two conveying platforms.

[0005] As can be seen from the above, the two conveying platforms will overlap in the vertical direction during movement. If the vertical driving module of the driving member is installed below the conveying platform, the vertical driving module will hinder the staggered movement of the two conveying platforms. Therefore, the vertical driving module of the driving member can only be installed on the outside of the conveying platform. One end of the conveying platform is fixed to the moving end of the vertical driving module, and the fixed end of the vertical driving module is installed on the moving end of the horizontal driving module. The horizontal driving module drives the vertical driving module and the conveying platform to slide horizontally together. Although this avoids the interference of the driving member with the conveying platform, the conveying platform can only be eccentrically and suspendedly arranged on the moving end of the vertical driving module. After the conveying platform moves for a long time, the supporting part of the conveying platform will be deformed, causing the conveying platform to be inclined. INNOVATION CONTENT

[0065] In order to make the above-mentioned objects, features and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0066] The light-receiving part in a solar cell module is the upper surface of a cell. In order to achieve the maximum light-receiving area in a limited area, adjacent cells are overlapped in the existing photovoltaic cell, but this will cause the solder ribbon to have excessive stress on the cell edge, and the cell edge is prone to hidden cracks or breakage. In order to solve the above problems, a film strip is placed between the overlapping parts of adjacent cells, and the film strip is used to buffer the stress of the solder ribbon on the cell edge.

[0067] At present, the film strip processing equipment outputs a plurality of film strips at a receiving station, and then the plurality of film strips are sent to a feeding station, and then a cell string device takes away the plurality of film strips at the feeding station. In order to improve the production efficiency, the existing film strip conveying mechanism usually adopts two sets of conveying assemblies to work alternately, each set of conveying assembly comprising a driving member and a conveying platform, and the driving members of the two sets of conveying assemblies drive the corresponding conveying platforms to move to the receiving station and the feeding station alternately.

[0068] However, the two conveying platforms have the same position at the receiving station and the feeding station. When the first conveying platform is at the receiving station, the second conveying platform is moving from the feeding station to the receiving station. Therefore, the first conveying platform needs to leave the receiving station and avoid the moving path of the second conveying platform. Therefore, the driving member of each conveying assembly includes a horizontal driving module and a vertical driving module. The horizontal driving module can drive the conveying platform to horizontally slide. The vertical driving module can drive the conveying platform to vertically lift. The driving member first lifts the conveying platform from the receiving station to a certain height. Then, the driving member drives the conveying platform to horizontally slide to above the feeding station. Then, the driving member drives the conveying platform to descend to the feeding station, so as to realize the staggered movement of the two conveying platforms.

[0069] As can be seen from the above, the two conveying platforms will overlap in the vertical direction during movement. If the vertical driving module of the driving member is installed below the conveying platform, the vertical driving module will hinder the staggered movement of the two conveying platforms. Therefore, the vertical driving module of the driving member can only be installed on the outer side of the conveying platform. One end of the conveying platform is fixed to the moving end of the vertical driving module. The fixed end of the vertical driving module is installed on the moving end of the horizontal driving module. The horizontal driving module drives the vertical driving module and the conveying platform to horizontally slide together. Although this avoids the interference of the driving member to the conveying platform, the conveying platform can only be eccentrically and suspendedly arranged on the moving end of the vertical driving module. After long-term movement of the conveying platform, the supporting part of the conveying platform will be deformed, causing the conveying platform to be inclined.

[0070] Therefore, the application provides an alternating conveying mechanism. As shown in Figure 1 The alternating conveying mechanism includes a base 10, a first conveying mechanism 20 and a second conveying mechanism 30. The first conveying mechanism 20 includes a first driving assembly 21, two first supporting members 22 and a first conveying platform 23. The first conveying platform 23 is configured to carry and fix a plurality of film strips. The bottom ends of the two first supporting members 22 are movably arranged on the base 10 along a first horizontal direction (X direction) in the base 10. The top ends of the two first supporting members 22 are fixed to the first conveying platform 23 along a second horizontal direction (Y direction) in the base 10. Figure 1 The first conveying platform 23 is movably arranged on the two first supporting members 22 along a third horizontal direction (Z direction) in the base 10. The first driving assembly 21 is arranged on the base 10 and is connected to the two first supporting members 22. The first driving assembly 21 drives the two first supporting members 22 to move along the first horizontal direction (X direction) in the base 10. The second conveying mechanism 30 is arranged on the base 10 and is connected to the first conveying mechanism 20. The second conveying mechanism 30 drives the first conveying platform 23 to move along the third horizontal direction (Z direction) in the base 10. Figure 1The driving end of the first driving assembly 21 is connected with at least one first support 22, and the first driving assembly 21 is configured to drive the two first supports 22 to reciprocate along the first horizontal direction, so as to drive the first conveying platform 23 to alternately move to the material receiving station and the material feeding station. The second conveying mechanism 30 comprises a second driving assembly 31, a transverse moving piece 32, two sets of guide assemblies 33 and a second conveying platform 34. The second conveying platform 34 is configured to at least carry and fix a plurality of film strips. The two sets of guide assemblies 33, the transverse moving piece 32 and the second conveying platform 34 are located between the two first supports 22. The transverse moving piece 32 is arranged on the base 10 and located between the two sets of guide assemblies 33 and can reciprocate along the first horizontal direction. The second conveying platform 34 is arranged on the transverse moving piece 32 and can ascend and descend. The driving end of the second driving assembly 31 is connected with the transverse moving piece 32. The second driving assembly 31 is configured to drive the transverse moving piece 32 and the second conveying platform 34 to alternately move to the material receiving station and the material feeding station along the first horizontal direction. The first set of guide assemblies 33 is arranged between the first end of the second conveying platform 34 along the second horizontal direction and the base 10. The second set of guide assemblies 33 is arranged between the second end of the second conveying platform 34 along the second horizontal direction and the base 10. The two sets of guide assemblies 33 are configured to drive the second conveying platform 34 to ascend and descend from both ends while the second conveying platform 34 reciprocates along the first horizontal direction. The two first supports 22 and the first conveying platform 23 enclose a passing space for the second conveying platform 34 to pass below the first conveying platform 23.

[0071] Specifically, the bottom ends of the two first supports 22 are arranged on the base 10 and can reciprocate along the first horizontal direction through a sliding guide pair composed of a linear guide rail and a sliding block.

[0072] It can be seen that the two ends of the first conveying platform 23 and the second conveying platform 34 of the alternate conveying mechanism are respectively assembled on the base 10 through the first support 22 and the guide assembly 33, which realizes stable and reliable support of the two ends of the first conveying platform 23 and the second conveying platform 34 along the second horizontal direction, avoids the deflection of the first conveying platform 23 and the second conveying platform 34 after long-term movement, and ensures the long-term stable conveying of the film strips by the first conveying platform 23 and the second conveying platform 34. Moreover, the second conveying platform 34 can ascend and descend while reciprocating along the first horizontal direction through the guide assembly 33, so that the second conveying platform 34 can pass below the first conveying platform 23, thereby realizing the alternate and staggered continuous conveying of the film strips, improving the conveying efficiency, and realizing compact structure and small space occupation.
