Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic module production equipment, and particularly to a glass transfer device in a solar photovoltaic module production line. Background Art

[0002] Solar photovoltaic modules are the core part and the most important part in a solar power generation system. A solar photovoltaic module generally consists of tempered glass, EVA, a battery cell layer, EVA, fiberglass, and a backplane stacked from bottom to top in sequence. In a conventional solar photovoltaic module production line, workers are required to lift the glass plates stacked and stored on a glass plate placement rack to an EVA laying station for module stacking. When the glass plates are stacked and stored on the glass plate placement rack, separator papers are placed between adjacent glass plates for isolation. The above manual operation method of handling glass plates has the following disadvantages: (1) Workers have a high labor intensity and low work efficiency; (2) It is difficult to ensure the surface cleanliness of the glass plates during manual handling. For example, if a glass plate with dust attached to its surface is used for module stacking at the EVA laying station, it will affect the product quality of the solar photovoltaic module, and in severe cases, it will lead to the scrapping of the photovoltaic module, not only reducing the work efficiency but also increasing the production cost.

[0015] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] Such as Figure 1 , Figure 2 , Figure 3As shown in the figure, a glass transfer device includes: a frame 1, on which a transverse transfer track 2 extending through the glass plate picking station and the glass plate output station is provided. On the frame 1 at the glass plate picking station, a glass plate placement rack 3 for stacking and storing glass plates is provided. On the frame 1 at the glass plate output station, a conveyor belt 4 for transporting the glass plates to the EVA laying station is provided. Above the output end of the conveyor belt 4 on the frame 1, a dust removal brush 5 and a dust removal fan 6 are sequentially arranged along the glass plate conveying direction. The dust removal brush 5 is used to clean and remove dust from the surface of the glass plates conveyed by the conveyor belt 4, and the dust removal fan 6 is used to blow and remove dust from the surface of the glass plates conveyed by the conveyor belt 4. A transfer mechanism capable of grasping the glass plates on the glass plate placement rack 3 and transferring the grasped glass plates to the conveyor belt 4 is provided on the transverse transfer track 2. The transfer mechanism includes: a translation frame 7 slidably arranged on the transverse transfer track 2, and the translation frame 7 can move along the transverse transfer track 2 driven by a first driving mechanism. In this embodiment, the structure of the first driving mechanism includes: a rack 8 parallel to the transverse transfer track 2 is provided on the frame 1. A translation motor 9 is vertically installed at the bottom of the translation frame 7. The output shaft of the translation motor 9 extends downward and is installed with a gear 10 meshing with the rack 8. The translation motor 9 drives the gear 10 to move along the rack 8 to synchronously drive the translation frame 7 to move along the transverse transfer track 2. A longitudinal transfer track 11 is vertically arranged on the translation frame 7. A longitudinal transfer frame 12 is slidably arranged on the longitudinal transfer track 11. The longitudinal transfer frame 12 can move up and down along the longitudinal transfer track 11 driven by a second driving mechanism. In this embodiment, the structure of the second driving mechanism includes: a lifting motor 13 is vertically installed at the top of the translation frame 7. The output shaft of the lifting motor 13 is connected with a lifting lead screw 14. The lifting lead screw 14 passes upward through the longitudinal transfer frame 12 and is threadedly connected with the longitudinal transfer frame 12. The lifting motor 13 drives the lifting lead screw 14 to rotate to synchronously drive the longitudinal transfer frame 12 to move up and down along the longitudinal transfer track 11. A plurality of suction cup assemblies 15 for sucking the glass plates are arranged on the longitudinal transfer frame 12.

[0017] In this embodiment, the structure of the suction cup assembly includes: a mounting plate 16 fixed on the longitudinal moving frame 12. There are mounting holes provided on the mounting plate 16. A hollow screw tube 17 is arranged in the mounting holes. An upper limit nut 18 and a lower limit nut 19 distributed on the upper and lower sides of the mounting plate 16 are threadedly connected to the outside of the hollow screw tube 17. The upper limit nut 18 and the lower limit nut 19 are oppositely arranged up and down to clamp the mounting plate 16, so that the hollow screw tube 17 is limited and fixed on the mounting plate 16. A hollow air rod 20 is inserted into the hollow screw tube 17. The upper end of the hollow air rod 20 extends upward out of the hollow screw tube 17 and is connected to a vacuum pump 22 through an air path 21. A fixing block 23 is arranged on the outside of the upper end of the hollow air rod 20. The hollow air rod 20 is hung on the hollow screw tube 17 through the fixing block 23. A vacuum suction cup 24 is installed at the lower end of the hollow air rod 20. A spring 25 is sleeved on the hollow air rod 20 between the vacuum suction cup 24 and the hollow screw tube 17. Both ends of the spring 25 respectively abut against the vacuum suction cup 24 and the hollow screw tube 17. Under the elastic force of the spring 25, the hollow air rod 20 always has a tendency to move downward relative to the hollow screw tube 17 until the fixing block 23 presses on the upper end face of the hollow screw tube 17. The above suction cup assembly has a simple structure and is convenient for installation and maintenance. In this embodiment, a glass sensor 26 is arranged on the longitudinal moving frame 12. When the longitudinal moving frame 12 moving to the glass picking station drives the suction cup assembly 15 to move downward until the vacuum suction cup 24 contacts the glass plate, as the longitudinal moving frame 12 continues to move downward, the longitudinal moving frame 12 will drive the hollow screw tube 17 and the glass sensor 26 to move downward relative to the hollow air rod 20 together. During the process of the air screw tube 17 moving downward relative to the hollow air rod 20, the air screw tube 17 will compress the spring 25. Under the elastic force of the spring 25, the vacuum suction cup 24 will press the glass plate downward. When the glass sensor 26 moves downward relative to the hollow air rod 20 along with the longitudinal moving frame 12 until it contacts the glass plate, the glass sensor 26 will send a in-place signal to the control system. After receiving the in-place signal, the control system will control to start the vacuum pump 22 to make the vacuum suction cup 24 suck the glass plate. On one side of the glass plate placement rack 3, a mounting bracket 27 is arranged. An isolation paper removing brush 28 that contacts the glass on the glass plate placement rack 3 is arranged on the mounting bracket 27. During the process of the longitudinal moving frame 12 moving a glass plate upward through the suction cup assembly 15, the isolation paper removing brush 28 will brush off the isolation paper electrostatically adsorbed on the lower surface of the glass plate to prevent the isolation paper from entering the EVA laying station together with the glass plate.

[0018] During operation, each motor, vacuum pump 22, dust removal fan 6, and conveyor belt 4 are all controlled by the control system to operate, and the glass sensor 26 is also connected to the control system for signal transmission. The control system first starts the translation motor 9, causing the translation motor 9 to move along the rack 8 through the driving gear 10, thereby synchronously driving the translation frame 7 and the longitudinal movement frame 12 to move along the transverse movement track 2 to the glass plate picking station. Then, the control system stops the operation of the translation motor 9 and simultaneously starts the lifting motor 13, causing the lifting motor 13 to drive the longitudinal movement frame 12 to move downward along the longitudinal movement track 11 by rotating the lifting lead screw 14. When the longitudinal movement frame 12 moves downward, it will synchronously drive the suction cup assembly 15 and the glass sensor 26 to move downward together. When the longitudinal movement frame 12 drives the suction cup assembly 15 to move downward until the vacuum suction cup 24 contacts the glass plate, as the longitudinal movement frame 12 continues to move downward, the longitudinal movement frame 12 will drive the hollow solenoid 17 and the glass sensor 26 to move downward relative to the hollow air rod 20. During the process of the air solenoid 17 moving downward relative to the hollow air rod 20, the air solenoid 17 will compress the spring 25. Under the elastic force of the spring 25, the vacuum suction cup 24 will press down tightly on the glass plate. When the glass sensor 26 moves downward relative to the hollow air rod 20 along with the longitudinal movement frame 12 until it contacts the glass plate, the glass sensor 26 will send a in-place signal to the control system. After receiving the in-place signal, the control system will stop the operation of the lifting motor 14 and simultaneously control the start of the vacuum pump 22 to cause the vacuum suction cup 24 to suck the glass plate. Then, the control system starts the lifting motor 14 again, causing the lifting motor 13 to drive the longitudinal movement frame 12 to move upward along the longitudinal movement track 11 to reset by rotating the lifting lead screw 14 in the reverse direction, so that the suction cup assembly 15 moves the sucked glass plate upward. During the process of the suction cup assembly 15 moving the glass plate upward, the separator paper removal brush 28 will brush off the separator paper electrostatically adsorbed on the lower surface of this glass plate to prevent the separator paper from entering the EVA laying station together with the glass plate. Then, the control system stops the operation of the lifting motor 13 and starts the translation motor 9 again, causing the translation motor 9 to move along the rack 8 through the driving gear 10, thereby synchronously driving the translation frame 7 and the longitudinal movement frame 12 to move along the transverse movement track 2 from the glass plate picking station to the glass plate output station.

[0019] Then the control system stops the operation of the translation motor 9 and starts the lifting motor 14 again, so that the lifting motor 13 drives the lifting lead screw 14 to rotate, driving the longitudinal movement frame 12 to move downward along the longitudinal movement track 11 until the glass plate sucked by the suction cup assembly 15 is placed on the conveyor belt 4. Then the control system stops the operation of the lifting motor 13 and starts the vacuum pump 22 again to release the glass plate by the vacuum suction cup 24. Then the control system starts the lifting motor 14 again, so that the lifting motor 13 drives the lifting lead screw 14 to rotate in the reverse direction, driving the longitudinal movement frame 12 and the suction cup assembly 15 to move upward along the longitudinal movement track 11 to reset together. Then the control system starts the translation motor 9 again, so that the translation motor 9 drives the gear 10 to move along the rack 8, synchronously driving the translation frame 7, the longitudinal movement frame 12 and the suction cup assembly 15 to move back to the glass plate picking station along the transverse movement track 2 to perform the picking operation of the next glass plate;

[0020] After the suction cup assembly 15 places the glass plate on the conveyor belt 4, the control system starts the conveyor belt 4 to convey the glass plate placed thereon from the glass plate output station to the EVA laying station. During the process of the conveyor belt 4 outputting the glass plate, the glass plate will pass through the dust removal brush 5 and the dust-attached fan 6 in sequence. The dust removal brush 5 will clean and remove the dust on the surface of the glass plate conveyed by the conveyor belt 4, and the dust-attached fan 6 will blow and remove the dust on the surface of the glass plate conveyed by the conveyor belt 4, so as to ensure that the glass plate enters the EVA laying station in a clean surface state.

[0021] The advantages of the present invention are: (1) low labor intensity of workers and high work efficiency; (2) it can conveniently transfer the glass plates stacked and stored on the glass plate placement rack to the EVA laying station, and can remove the dust on the surface of the glass plate before the glass plate is moved to the EVA laying station, ensuring the surface quality of the glass plate and improving the product quality of the solar photovoltaic module.

[0022] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in any other form. Any modification or equivalent change made according to the technical essence of the present invention still belongs to the scope of protection required by the present invention.
