However, this method requires complex screening and has low work efficiency.

[0004] Therefore, the present application provides a system that can quickly transport the frames in the frame stack to the next workstation (such as the gluing station). The frame loading system can not only quickly transport the frames, but also transport the long frames and short frames separately. Utility Model Content

[0034] During the production of photovoltaic modules, the installation of frames is an important process. The cross section of existing photovoltaic modules is generally rectangular, so a photovoltaic module needs to prepare two long frames 4 and two short frames 5 to complete the assembly. Figure 1 As shown, generally, long frames 4 are stacked together to form a long frame stack 1, and short frames 5 are stacked together to form a short frame stack 2. There is a separator paper in the frame stack for separating two adjacent layers of frames.

[0035] The existing installation is carried out by manual screening and classification, and then a group of classified frames are placed together, glued and subsequently installed. However, this method requires complex screening and has low work efficiency. Therefore, the present application provides a system that can quickly transport the frames in the frame stacking to the next work station (such as the gluing station). The frame loading system can not only quickly transport the frames, but also can transport the long frames 4 and the short frames 5 separately.

[0036] The following is combined with Figure 1-6 , further explain this application in detail.

[0037] Reference Figure 1 and Figure 2The photovoltaic module frame loading system includes a frame stacking, a frame conveying device, a waste collection bucket 18 and a manipulator 6. The frame stacking includes a long frame stacking 1 and a short frame stacking 2. As an implementable method, the present application has two groups of long frame stacking 1 and two groups of short frame stacking 2, with two frame conveying devices. The two groups of long frame stacking 1 and the two groups of short frame stacking 2 are arranged around the two frame conveying devices. The bottom of the manipulator 6 is provided with a ground rail 8 for the movement of the manipulator 6. The manipulator 6 is located between the frame stacking and the conveying device. During the movement of the manipulator 6 along the length direction of the ground rail 8, the long frame stacking 1 and the short frame stacking 2 and the conveying device are all within the range of movement of the manipulator 6. The frame conveying device includes a frame 16 and a belt line 3. In the present application, there are at least four belt lines 3. The four belt lines 3 are arranged vertically up and down along the frame 16. A light curtain 17 is also provided on the frame 16. The four belt lines 3 correspond to the four sides of the photovoltaic module respectively. It can be understood that the robot 6 in this application cooperates with the visual system (not shown in the figure) to place the long frames 4 and short frames 5 in the frame stacking on different belt lines 3 respectively, and transport them forward through the belt lines 3, thereby completing the sorting and transmission of the frames, and transporting the frames of different lengths to the next process.

[0038] As a possible implementation method, the first and second belt lines 3 can be used to transport long frames 4, and the third belt line 3 can be used to transport short frames 5; or the third and fourth belt lines 3 can be used to transport long frames 4, and the first and second belt lines 3 can be used to transport short frames 5. This application does not make specific limitations. In addition, there is a blocking blanking component at the output end of the belt line 3. The blocking blanking component is used to control the conveying process of the belt line 3. Each layer of the belt line 3 conveys frames of the same length to achieve gluing and installation of four frames in a group. After the gluing of one group of frames is completed, the blocking blanking mechanism controls the belt line 3 of each layer to convey the next frame. This part of the content is an implementation method that can be known to those skilled in the art, and this application will not elaborate on it in detail.

[0039] Reference Figure 3 and Figure 4A connecting plate 7 is provided at the bottom of the manipulator 6, and a mobile driving component 9 is provided on the connecting plate 7. The mobile driving component 9 is used to drive the connecting plate 7 to drive the manipulator 6 to move along the length direction of the ground rail 8. As an embodiment, the mobile driving component 9 includes a gear, a rack and a motor. The rack is provided on the side wall of the floor cabinet. The motor is provided on the connecting plate 7 and drives the gear to rotate. The gear and the rack are engaged with each other. When the motor drives the gear to rotate, the connecting plate 7 is driven to move. The two frame conveying devices in the present application are arranged side by side along the length direction of the ground rail 8, and the manipulator 6 includes at least a first movable arm 10, a second movable arm 11, a third movable arm 12 and a fourth movable arm 13. One end of the first movable arm 10 is rotatably set on the upper surface of the connecting plate 7, and the other end of the first movable arm 10 is rotatably connected to the second movable arm 11. The end of the second movable arm 11 away from the first movable arm 10 is rotatably connected to the third movable arm 12, and the end of the third movable arm 12 away from the second movable arm 11 is rotatably connected to the fourth movable arm 13. The fourth movable arm 13 is connected to a rotating motor 14, and the output shaft of the rotating motor 14 passes through the fourth movable arm 13 and is connected to the material picking tray 15. The rotating motor 14 is used to drive the material picking tray 15 to rotate. The surface of the material picking tray 15 is provided with a number of suction cups 19 and clamps 20. The use of suction cups 19 to suck and place the frame can make the frame picking and placing more convenient. The clamps 20 are used to remove the separating paper clips between two adjacent layers of frames and transport them to the waste collection bucket 18.

[0040] The action process of the manipulator 6 is: by cooperating with the visual camera to absorb the frames in the frame stacking, and placing the long frames 4 on two of the belt lines 3 of the frame conveying equipment, and placing the short frames 5 on the other two belt lines 3, the mobile drive component 9 drives the manipulator 6 to perform the above-mentioned conveying action while slowly moving along the length direction of the ground rail 8, so that after the manipulator 6 places one of the frame conveying equipment, it can quickly switch and start placing frames on the other frame conveying equipment, with a higher frame placement efficiency. Since the manipulator 6 has a first movable arm 10, a second movable arm 11, a third movable arm 12, a fourth movable arm 13 and a rotatable material picking tray 15, the manipulator 6 has more degrees of freedom of movement, and its turning and reversing are more flexible, which reduces the activity space of the manipulator 6 while meeting multi-directional transportation.

[0041] Reference Figure 5 and Figure 6, the frame 16 is also provided with several correction components, which are respectively located on both sides of each layer of the belt line 3, and are used to correct the two ends of the frame in the length direction during the process of the belt line 3 conveying the frame. The correction component includes a correction cylinder 21 and a blocking plate 22. The blocking plate 22 is arranged on the output shaft of the correction cylinder 21 and is close to the frame relative to the correction cylinder 21. The correction cylinder 21 is used to drive the blocking plate 22 to move in the direction close to the frame or away from the frame. A linear slide rail 23 is provided on the frame 16. The length direction of the linear slide rail 23 is the same as the length direction of the frame. A slider 24 is provided on the linear slide cabinet. The correction cylinder 21 is provided on the slider 24. The slider 24 slides along the length direction of the linear slide rail 23 and drives the correction cylinder 21 to move, thereby adapting to frames of different lengths for correction action.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
