Description

Technical Field

[0001] The present disclosure relates to a production tool for photovoltaic modules, and specifically, to a repair and grasping device for photovoltaic module strings. Background Art

[0002] During the production process of photovoltaic modules, string abnormalities may occur, and the abnormal strings need to be transported to the repair station for repair. The repair station needs to use a special grasping device to grasp the abnormal strings to avoid secondary contamination and fragmentation of the cells caused by manually handling the strings, and also avoid scratching the hands of the repair personnel, improving the repair qualification rate and repair safety.

[0003] However, due to the diverse types and specifications of photovoltaic modules, specifically, there are different types such as single-glass modules, double-glass modules, and flexible modules, and different specifications such as 9-piece, 10-piece, and 11-piece modules. There are various processes in which photovoltaic modules are prone to string abnormalities. Specifically, processes such as scribing by a scribing machine, string soldering by a string soldering machine, and lamination soldering by a lamination soldering machine may have a probability of contamination, hidden cracks, poor soldering, and fragmentation. The abnormal strings may be directly sent by the string inspection personnel of the current machine to the repair material box and then concentrated together on the repair table for string repair, or may be detected as abnormal during the EL (electroluminescence) detection process and then transported to the repair station, resulting in a high diversity of abnormal strings at the repair station. The grasping devices of the existing technologies are difficult to effectively adapt to these abnormal strings, increasing the working pressure of the repair personnel and forcing the factory to produce different specifications of grasping devices for different specifications of abnormal strings, indirectly increasing the operating cost of the factory.

[0004] In view of this, it is necessary to design a repair and grasping device for photovoltaic module strings that can effectively solve the above technical problems. Summary of the Utility Model

[0032] As Figure 1 、 Figure 2 and Figure 4 shown, the present disclosure provides a repair grabbing device for a photovoltaic module string. The repair grabbing device for a photovoltaic module string in this embodiment includes a hollow tube 1 and a suction cup 3. The hollow tube 1 forms a cavity 2, an installation structure, and a plurality of openings. At least one of the plurality of openings is used to communicate the cavity 2 with a vacuum source, and the other openings are used to communicate the cavity 2 with the suction cup 3. Thus, the vacuum source can communicate with the suction cup 3 through the openings and the cavity 2, causing the suction cup 3 to generate suction force to adsorb the abnormal string. Thus, the repair personnel can directly grasp the hollow tube 1 and adsorb the abnormal string through the suction cup 3, avoiding the problems of secondary pollution and fragment damage caused by the repair personnel manually holding the string, and avoiding the hands of the repair personnel being scratched during the grabbing process, improving the repair qualification rate and safety. And the repair grabbing device for a photovoltaic module string is also provided with an installation structure, which is used to connect the repair grabbing device for a photovoltaic module string with another repair grabbing device for a photovoltaic module string, improving the expandability of the repair grabbing device for a photovoltaic module string, so that the repair grabbing device for a photovoltaic module string can be adapted to abnormal strings of different specifications.

[0033] In some embodiments, as Figure 1 and Figure 4 shown, the installation structure in this embodiment includes a threaded hole 4 provided at one end of the hollow tube 1 and a threaded portion 5 provided at the other end of the hollow tube 1. The threaded hole 4 and the threaded portion 5 on adjacent two hollow tubes 1 are adapted to each other, so that a plurality of hollow tubes 1 can be assembled together by threaded connection to extend the hollow tube 1, facilitating the repair personnel to freely expand according to the length of the abnormal string.

[0034] In some embodiments, as Figure 1 、 Figure 4 and Figure 5As shown, the opening includes a threaded hole opening 17 provided at the threaded hole 4 and a threaded portion opening 18 provided at the threaded portion 5. Both the threaded hole opening 17 and the threaded portion opening 18 communicate with the cavity 2. One of the threaded hole opening 17 and the threaded portion opening 18 is used to connect to a vacuum source, and the other is connected to the plug 6. When multiple photovoltaic module string repair gripping devices form an extended gripping device, the corresponding threaded hole openings 17 and threaded portion openings 18 at the connection of the multiple photovoltaic module string repair gripping devices are connected, so that the cavities 2 of the multiple photovoltaic module string repair gripping devices are connected. In this embodiment, the threaded hole opening 17 at one end of the extended gripping device is used to connect to a vacuum source, and the threaded portion opening 18 at the other end is connected to the plug 6. In some other embodiments, the threaded portion opening 18 at one end of the extended gripping device is used to connect to a vacuum source, and the threaded hole opening 17 at the other end is connected to the plug 6.

[0035] In some embodiments, as Figure 2 described, the photovoltaic module string repair gripping device of the present disclosure further includes a bracket. The hollow tube 1 is connected to the suction cup 3 through the bracket. The bracket forms a vacuum flow channel, and the opening is connected to the suction cup 3 through the vacuum flow channel to provide suction to the suction cup 3. By providing the bracket in this embodiment, the distance between the hollow tube 1 and the suction cup 3 is increased to reduce the interference between the photovoltaic module and the hollow tube 1 when adsorbing the photovoltaic module.

[0036] In some embodiments, as Figure 2 and Figure 3 shown, the opening of this embodiment includes a hollow tube mounting port 8. The bracket forms a vacuum flow channel and a bracket mounting port 9. The bracket mounting port 9 communicates with the suction cup 3 through the vacuum flow channel. An air tube 7 is connected between the hollow tube mounting port 8 and the bracket mounting port 9. Thus, the vacuum source and the suction cup 3 are connected through the cavity 2, the hollow tube mounting port 8, the air tube 7, the bracket mounting port 9, and the vacuum flow channel to realize the adsorption of the abnormal string.

[0037] In some embodiments, as Figure 2 shown, the hollow tube mounting port 8 is provided on the side of the hollow tube 1 away from the suction cup 3, and the bracket mounting port 9 is provided on the side of the bracket away from the suction cup 3, so that the air tube 7 is away from the suction cup 3, reducing the interference of the air tube 7 on the process of gripping the photovoltaic module.

[0038] In some embodiments, both ends of the air tube 7 of this embodiment are connected to the hollow tube mounting port 8 and the bracket mounting port 9 respectively through quick connectors. The quick connectors facilitate the installation of the air tube 7 and improve the sealing performance between the air tube 7 and the hollow tube mounting port 8 as well as between the air tube 7 and the bracket mounting port 9. In some other embodiments, quick connectors are also provided at the threaded hole opening 17 or the threaded portion opening 18, and the quick connectors are connected to the vacuum source through the air tube 7 to improve the sealing performance.

[0039] In some embodiments, as Figures 1 to 3 shown, the bracket includes a plurality of bracket seats 11 and bracket bodies 12 corresponding to the number of the bracket seats 11. The plurality of bracket seats 11 are symmetrically arranged on the outer peripheral surface of the hollow tube 1 along the length direction of the hollow tube 1. The plurality of bracket seats 11 are parallel to each other and perpendicular to the hollow tube 1. The bracket seats 11 are formed with bracket through holes. The bracket body 12 includes a flange stop portion 14 and a sliding fit portion 15. The diameter of the flange stop portion 14 is larger than that of the sliding fit portion 15. A stop step surface 16 is formed between the flange stop portion 14 and the sliding fit portion 15. The sliding fit portion 15 is slidably arranged in the bracket through hole, and the bracket body 12 is perpendicular to the bracket seat 11. The stop step surface 16 and the bracket seat 11 are mutually stopped. The suction cup 3 is arranged at one end of the sliding fit portion 15 away from the flange stop portion 14. In the use state of the photovoltaic module string repair and grasping device of this embodiment, the length direction of the bracket seat 11 is the same as or close to the horizontal direction, and the length direction of the bracket body 12 is the same as or close to the vertical direction. Thus, the two bracket bodies 12 corresponding to a pair of bracket seats 11 are spaced apart by a certain distance along the length direction of the bracket seat 11, and each pair of bracket bodies 12 corresponding to each bracket seat 11 are spaced apart by a certain distance along the length direction of the hollow tube 1. Thus, the suction cups 3 are spaced apart by a certain distance to improve the grasping stability, and the sliding fit portion 15 can slide along its length direction to change the distance between the suction cup 3 and the bracket body 12 to adapt to the abnormal string with an uneven surface. In addition, the present disclosure is not limited to the above azimuth structures of the bracket seat 11, the bracket body 12, and the hollow tube 1, as long as it is suitable for the suction cup 3 to contact the abnormal string.

[0040] In some embodiments, as Figures 1 to 3 shown, the bracket through hole of this embodiment is set as a bracket through groove 13. The length direction of the bracket through groove 13 is the same as the length direction of the bracket seat 11. In the use state of the photovoltaic module string repair and grasping device of this embodiment, the length direction of the bracket through groove 13 is the horizontal direction. Thus, the sliding fit portion 15 can move along the length direction of the bracket through groove 13 to change the position of the suction cup 3 in the horizontal direction, so as to ensure that when the photovoltaic module string repair and grasping device adsorbs abnormal strings of different specifications, the suction cup 3 can correspond to the correct adsorption position.

[0041] In some embodiments, as Figures 1 to 3As shown, a spring 10 is sleeved on the sliding fit portion 15, and the spring 10 is located between the stop step surface 16 and the support seat 11. One end of the spring 10 is connected to the stop step surface 16, and the other end is connected to the support seat 11. During the use of the photovoltaic module string repair grasping device in this embodiment, the photovoltaic module string repair grasping device is placed on the abnormal string. The protruding part of the abnormal string first contacts the suction cup 3, and the photovoltaic module string repair grasping device is pressed down, causing the corresponding spring 10 of the protruding part to stretch. The stretched spring 10 provides a force towards the abnormal string to the support body 12, ensuring that the corresponding suction cup 3 closely adheres to the abnormal string. Further pressing down until the suction cup 3 fully contacts the surface of the abnormal string.

[0042] An embodiment of a photovoltaic module string repair grasping device provided by the present utility model is as Figures 1 to 5As shown in the figure, the repair and grasping device for photovoltaic module strings includes: a hollow tube 1, a suction cup 3, a plug 6, an air pipe 7, a support seat 11, and a support body 12. A plurality of support seats 11 are symmetrically arranged on the outer peripheral surface of the hollow tube 1 along the length direction of the hollow tube 1. The support seats 11 are perpendicular to the hollow tube 1, and the plurality of support seats 11 are in the same plane. A support through groove 13 is formed on the support seat 11. The length direction of the support through groove 13 is the same as the length direction of the support seat 11. The support body 12 forms a flange stop portion 14 and a sliding fit portion 15. The diameter of the flange stop portion 14 is larger than the diameter of the sliding fit portion 15. A stop step surface 16 is formed between the flange stop portion 14 and the sliding fit portion 15. The sliding fit portion 15 is slidably arranged in the support through groove 13, and the support body 12 is perpendicular to the support seat 11 and the hollow tube 1. A spring 10 is sleeved on the sliding fit portion 15. The two ends of the spring 10 are respectively connected to the stop step surface 16 and the support seat 11. A suction cup 3 is installed at one end of the sliding fit portion 15 away from the flange stop portion 14. The hollow tube 1 forms a cavity 2. An installation opening 8 of the hollow tube is formed at one end of the hollow tube 1 away from the suction cup 3, and the cavity 2 is communicated with the installation opening 8 of the hollow tube. A support installation opening 9 is formed at one end of the flange stop portion 14 away from the sliding fit portion 15. The installation opening 8 of the hollow tube and the support installation opening 9 are connected through the air pipe 7. Quick connectors are provided between the air pipe 7 and the installation opening 8 of the hollow tube and between the air pipe 7 and the support installation opening 9, so as to facilitate the installation of the air pipe 7 and improve the sealing performance. The support body 12 forms a vacuum flow channel communicating the support installation opening 9 and the suction cup 3. Threaded holes 4 and threaded portions 5 are respectively formed at both ends of the hollow tube 1. The threaded holes 4 and the threaded portions 5 of two adjacent hollow tubes 1 are matched. A threaded hole opening 17 communicating the cavity 2 is formed at the threaded hole 4, and a connecting threaded portion opening 18 communicating the cavity 2 is formed at the threaded portion 5. When the size of the repair and grasping device for photovoltaic module strings in this embodiment is adapted to the size of the abnormal string, a quick connector is installed at the threaded hole opening 17, and a true air source is communicated through the air pipe 7. A plug 6 is installed at the installation position of the threaded portion opening 18, and sealing is achieved through the plug 6. Thus, the suction cup 3 can communicate with the true air source through the vacuum flow channel, the support installation opening 9, the air pipe 7, the installation opening 8 of the hollow tube, the cavity 2, and the threaded hole opening 17, and an adsorption force is formed at the suction cup 3. When the size of the repair and grasping device for photovoltaic module strings in this embodiment does not meet the size of the abnormal string, the extended grasping device is assembled through the threaded fit connection of the threaded holes 4 and the threaded portions 5. The cavities 2 of a plurality of repair and grasping devices for photovoltaic module strings are communicated through the threaded hole openings 17 and the threaded portion openings 18. A quick connector is installed at the threaded hole opening 17 at one end of the extended grasping device, and a true air source is communicated through the air pipe 7. A plug is installed at the threaded portion opening 18 at the other end to form a seal. Thus, the extension of the repair and grasping device for photovoltaic module strings is realized through the threaded holes 4 and the threaded portions 5 to adapt to abnormal strings of different sizes.Before the suction cup 3 has an abnormal adsorption of the string, it is possible to control the sliding fit portion 15 to slide along the length direction of the support through groove 13, so that the suction cup 3 moves to the correct adsorption position, improving the adsorption ability for abnormal strings of different specifications. Moreover, the photovoltaic module string repair and grasping device of this embodiment is provided with a sliding fit portion 15 and a spring 10 to provide a compression space for the suction cup 3. When sucking the string, by pressing down the photovoltaic module string repair and grasping device, the protruding part of the abnormal string first contacts the suction cup 3. Continuing to press down, the sliding fit portion 15 corresponding to the protruding part slides to the side away from the suction cup 3, so that the suction cups corresponding to the other sliding fit portions 15 approach the surface of the abnormal string, increasing the number of suction cups 3 in contact with the abnormal string and improving the adsorption ability. And the spring 10 corresponding to the convex part is stretched, and the stretched spring 10 provides a force towards the abnormal string to the support body 12, ensuring that the corresponding suction cup 3 closely adheres to the abnormal string.

[0043] As can be seen from the above description, the advantages of the present disclosure generally lie in: First, it avoids manually holding the string, avoids secondary pollution and fragmentation, and improves the safety of the repair work; Second, multiple photovoltaic module string repair and grasping devices can be assembled through the installation structure to adapt to abnormal strings of different sizes; Third, the support body can slide along the support through groove, being suitable for moving the suction cup to the correct adsorption position; Fourth, the support body can slide along its axial direction, providing a compression space for the suction cup 3 and increasing the number of suction cups in contact with the abnormal string.
