Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic module auxiliary devices, in particular to a double-glass frame conveying system for a laminator. Background Art

[0002] A laminator refers to a mechanical device for pressing multiple layers of materials together, also known as a solar photovoltaic module laminator. It is a mechanical device that presses EVA, solar cells, tempered glass, and backsheets into a rigid whole under high-temperature and vacuum conditions. The double-glass frame of the laminator is a device used in the production of double-glass modules. When preparing double-glass modules, in order to prevent the upper and lower two pieces of glass from being misaligned during lamination and reduce the excessive outflow of the surrounding encapsulation film resulting in lack of glue, usually during lamination, double-glass frames are added to the four sides of the double-glass module. Adding frames to the laminator is a common process technology for the production of double-glass modules.

[0003] Before the double-glass module enters the lamination chamber of the laminator, double-glass frames are added to the four sides of the double-glass module on the loading table. Subsequently, the double-glass frame and the double-glass module enter the lamination chamber together for lamination. After lamination is completed, the double-glass frame and the double-glass module flow out of the lamination chamber together and enter the unloading table. At this time, the double-glass frame is removed, and the double-glass module continues to flow to the next process, while the removed double-glass frame needs to return to the loading table for subsequent use by double-glass modules. However, the existing double-glass frames of the laminator need to be manually carried. The double-glass frames are carried from the unloading table of the laminator to the loading table for recycling.

With such a setting, the loading device 1 frames the double-glass frame 7 on the double-glass module and sends them into the laminator 3 together. The unloading device 2 conveys the double-glass frame 7 on the double-glass module after lamination. The second transfer device can pick up the double-glass frame 7 and move the double-glass frame 7 onto the return conveying line 4. The return conveying line 4 continues to convey the double-glass frame 7, and then the first transfer device places the double-glass frame 7 on the loading device 1, thus completing an automated workflow of repeated loading and unloading of the double-glass frame 7, realizing the automatic circulation of the double-glass frame 7, reducing the safety risk during the manual movement of the double-glass frame 7, improving the automation level, and reducing the labor cost. It should be noted that the first direction and the second direction are respectively as Figure 1 shown by the two arrow directions in

[0042] Optionally, the loading device 1 includes a first conveying component, a base 5, and a picking and placing device 6.

The first driving member is connected to the connecting plate by transmission and can drive the connecting plate to move in the vertical direction. The second driving member is connected to the connecting plate, and the second driving member can drive the pressure rod to move in the vertical direction so that the double glass frame 7 is clamped between the connecting plate and the pressure rod. In this way, when the first transport device clamps and transports the double glass frame 7 to the loading device 1, the first driving member drives the connecting plate, and the second driving member moves upward. The first transport device places the double glass frame 7 on the connecting plate. At this time, the second driving member drives its cantilever to rotate, so that the pressure rod arranged under the cantilever presses the frame to limit it on the connecting plate. Finally, the first driving member transports the double glass frame 7 downward until it is placed on the first conveying assembly, and the first conveying assembly continues to transport the double glass frame 7. Specifically, the first driving member and the second driving member are both cylinders.

[0044] Furthermore, the base 5 is a cube, and a pick-up and placement device 6 is provided at the four corners of the base 5.

The third drive member 13 is drivingly connected to the lifting plate 14 and can drive the lifting plate 14 to move in the vertical direction.

The linear guide rail 16 extends along the second direction. The slider 17 is slidably arranged on the linear guide rail 16. The fourth drive member 15 is drivingly connected to the slider 17 and can drive the slider 17 to move. The slider 17 is connected to the rack 18, and the rack 18 meshes with the gear 19. The gear 19 is connected to the rotating disk 11. Specifically, both the third drive member 13 and the fourth drive member 15 are cylinders. With such an arrangement, when the double-glass frame 7 is placed on the commutation device 8, the third drive member 13 drives the placement rack 12, the rotating disk 11, and the rotating drive device to move upward to a specified position. At this time, the fourth drive member 15 drives the slider 17 to move on the linear guide rail 16, so that the slider 17 drives the rack 18 to move, and the rack 18 further drives the gear 19 to rotate 90 degrees to adjust and change the position of the double-glass frame 7.

[0048] Furthermore, the lifting drive device further includes a bottom plate 20, a plurality of guide columns 21, and a plurality of linear bearings 22.

[0049] Optionally, the first transfer device includes a first drive mechanism, a flight frame 23, a base frame 24, and a plurality of jaw assemblies 25. The flight frame 23 extends along the first direction. The base frame 24 is slidably arranged on the flight frame 23 and is located above the plurality of loading devices 1. The plurality of jaw assemblies 25 are connected to the base frame 24 and are used to clamp the double-glass frame 7. The first drive mechanism is drivingly connected to the base frame 24 and can drive the base frame 24 to move.

[0050] Further, the clamping jaw assembly 25 includes a second driving mechanism, a third driving mechanism and a clamping member, the second driving mechanism is arranged on the base frame 24, and the second driving mechanism is connected to the third driving mechanism by transmission, and can drive the third driving mechanism to move in the vertical direction, the third driving mechanism is connected to the clamping member by transmission, and can drive the clamping member to move in the second direction, so that the clamping member clamps the double glass frame 7. Further, the base frame 24 is square, the number of the clamping jaw assemblies 25 is four, and the four clamping jaw assemblies 25 are correspondingly arranged at the four corners of the base frame 24. In this arrangement, when the clamping jaw assembly 25 clamps the double glass frame 7, the second driving mechanism first drives the third driving mechanism and the clamping member to move downward, and then the third driving mechanism drives the clamping member to move in the second direction, at which time, the double glass frame 7 is between the two clamping jaws of the clamping member, and the two clamping jaws of the clamping member are closed to clamp the double glass frame 7.

[0051] Optionally, the double glass frame conveying system of the laminator further includes a plurality of storage devices 26, and the plurality of storage devices 26 correspond to a plurality of return conveying lines 4 one by one. The storage devices 26 are arranged on the return conveying line 4 and are used to store the double glass frames 7. During the actual operation of the return conveying line 4, a plurality of double glass frames 7 will be laid on the return conveying line 4. Since the length of the return conveying line 4 is certain, the number of double glass frames 7 that can be conveyed is limited. Therefore, by arranging the storage device 26 on the return conveying line 4, the number of double glass frames 7 conveyed on the return conveying line 4 is increased. By stacking a plurality of double glass frames 7 at the position of the storage device 26, when there is a vacant position on the return conveying line 4, the double glass frames 7 in the storage device 26 will be conveyed to the return conveying line 4, thereby improving the subsequent processing and production efficiency.

Among them, both the main lifting assembly 29 and the auxiliary lifting assemblies 30 are drive chain structures. The main lifting assembly 29 is driven by a drive motor. A number of pallet plates are provided on the chain of the main lifting assembly 29 close to the third conveying assembly 28, and the pallet plates are used to support the double-glass frame 7. A number of support rods 31 are provided on one side of the auxiliary lifting assembly 30 close to the third conveying assembly 28. The distance between two adjacent pallet plates is equal to the distance between two adjacent support rods 31. When the storage device 26 needs to store the double-glass frame 7 entering it, when the double-glass frame 7 completely enters above the third conveying assembly 28, the third conveying assembly 28 stops moving. The drive motor drives the main lifting assembly 29 to drive the chain on the auxiliary lifting assembly 30 to rotate, so that the double-glass frame 7 restricted between the pallet plates and the support rods 31 is lifted, so that the double-glass frame 7 on the pallet plates and the support rods 31 does not move along with the movement of the third conveying assembly 28; when the storage device 26 no longer needs to store the double-glass frame 7, at this time, the lifting assembly does not act, the third conveying assembly 28 does not stop moving, and the double-glass frame 7 on the third conveying assembly 28 will be transported out of the storage device 26 and continue to be transported through the return conveying line 4.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention.
