Description

Technical Field

[0002] Photovoltaic glass is composed of glass, solar cells, film, back glass, special metal wires, etc. It is widely used, such as solar smart windows, solar pavilions and photovoltaic glass building roofs, as well as photovoltaic glass curtain walls. It is divided into two categories: crystalline silicon photovoltaic glass and thin-film photovoltaic glass. The production process of photovoltaic glass usually requires glass cleaning, coating, drying, curing, cutting, inspection, packaging and other steps.

[0003] In the prior art, there are already production lines for photovoltaic glass. For example, Chinese patent CN201210036896.X provides a process for manufacturing ultra-white float solar cell glass and its products. The process includes the following steps: (1) raw material batching; (2) feeding and melting; (3) clarification; (4) homogenization; (5) tin stripping; (6) annealing; (7) cutting. The process for manufacturing ultra-white float solar cell glass provided by the present invention can produce ultra-white float solar cell glass with a thickness of 2.5 mm. The glass has high light transmittance, low reflectivity and light unit weight, and is very suitable for the photovoltaic industry as a substrate for photoelectric conversion and a panel for a photothermal conversion system for the manufacture of solar cells. In addition, the ultra-white float solar cell glass produced by the process has low production cost, thereby reducing the production cost of the entire photovoltaic industry chain.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0052] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0053] The present invention comprises:

[0054] A production line for packaging photovoltaic glass bottom sheets, such as Figure 1 As shown, it includes a sheet loading roller 1, a packaging cleaning machine 2, a detection roller 5, and a conveying roller 4 which are sequentially arranged in a straight line, and also includes a plurality of sheet turning devices 3;

[0055] The flap turning devices 3 are arranged at intervals on the conveying roller 4;

[0056] The sheet unloading station 6 is arranged on the side of the conveying roller 4

[0057] The loading roller 1 receives photovoltaic glass input from the outside;

[0058] The packaging and cleaning machine 2 cleans the photovoltaic glass;

[0059] The inspection roller 5 inspects the photovoltaic glass and then inputs it into the conveying roller 4;

[0060] The conveying roller 4 conveys the photovoltaic glass to the corresponding flipping device 5 according to the detection result of the detection roller;

[0061] The flipping device 3 obtains the corresponding photovoltaic glass and flips it to the corresponding unloading station 6;

[0062] The moving line formed by the sheet turning device 3 and the sheet unloading station 6 is arranged vertically relative to the conveying roller 4 .

[0063] Specifically, in view of the problem that the photovoltaic glass production line in the prior art is mainly carried out manually during the finished product cleaning and packaging process, which is costly and inefficient, the above-mentioned automatic glass cleaning and sorting production line is introduced in this embodiment, and the conveying roller 4 is reasonably arranged, and a straight conveying roller 4 is set behind the packaging washing machine 2 and the detection roller 5 to achieve efficient transportation of the cleaned photovoltaic glass. The classified photovoltaic glass is also turned over by the flipping device 3, which is convenient for the unloading station to lay paper on the input photovoltaic glass and then carry out the packaging and transportation process.

[0064] Specifically, Figure 1 The diagram shows a schematic diagram of a workshop, with a pair of mirror-imaged production lines on the upper and lower sides. Taking the production line on the upper side as an example, the loading roller 1 arranged along the long axis of the workshop receives the photovoltaic glass input from the outside, and then sends it to the packaging and cleaning machine 2 for cleaning by spraying and other processes. The packaging and cleaning machine 2 is used for cleaning the finished photovoltaic glass before it comes off the line, and is mainly composed of rollers, equipment frames, cleaning systems, air drying systems, and water systems.

[0065] The front stage of the loading roller 1 uses an AGV handling robot to connect to the previous station. In order to achieve a better conveying effect, an AGV handling robot is used between the front stage elevator of the previous process and the loading roller for conveying, and then for cleaning and packaging. After the unloading is completed, it is packaged and sent to the finished product warehouse for storage.

[0066] The rear stage of the packaging and cleaning machine 2 is provided with an inspection roller 5 which is also arranged along the long axis direction. The inspection roller 5 performs an appearance inspection on the photovoltaic glass by visual means or other equivalent means to determine whether the photovoltaic glass has defects, the type or severity of the defects, and generates corresponding inspection results, including qualified products, agreed products and scrap products.

[0067] On this basis, the flap turning device 3 comprises:

[0068] A first flipping device 3A, the first flipping device 3A is used to receive photovoltaic glass with a test result of being qualified;

[0069] The second flipping device 3B is used to receive the photovoltaic glass with a detection result of being a contract product;

[0070] The third flipping device 3C is used to receive photovoltaic glass that is detected as waste.

[0071] Specifically, in order to realize the classified storage of photovoltaic glass of different grades, in this embodiment, a plurality of flipping devices 3 corresponding to different classifications are set according to the product quality inspection level. The first flipping device 3A is used to receive photovoltaic glass with a qualified product as the inspection result, the second flipping device 3B is used to receive photovoltaic glass with a negotiated product as the inspection result, and the third flipping device 3C is used to receive photovoltaic glass with a rejected product as the inspection result.

[0072] Among them, a plurality of first film turning devices 3A can be provided according to the product yield to improve the film output efficiency.

[0073] And, usually, the above-mentioned flap turning devices 3 can be arranged arbitrarily, and only the third flap turning device 3C needs to be arranged at the end. In one embodiment, a re-cleaning station is arranged beside the production line, and the second flap turning device 3B can be arranged in advance to facilitate transportation to the re-cleaning station.

[0074] In one embodiment, the third flap turning device 3C is arranged at the rear end of the conveying roller;

[0075] The third flap turning device is an overpass roller conveyor.

[0076] A waste hopper 34 is also provided at the rear of the third flap turning device 3C;

[0077] When the lower sheet station 6 corresponding to the third sheet turning device 3C is saturated, the third sheet turning device 3C directly inputs the photovoltaic glass detected as waste into the waste hopper 34 .

[0078] Specifically, in order to achieve better processing efficiency, in this embodiment, the third flipping device 33 is set as an overpass roller and is set at the end of the conveying roller 4. The overpass roller omits the flipping sun gear mechanism relative to the above-mentioned flipping device, and extends the second flipping device roller to one side of the first flipping device roller, which is used to turn the waste glass to the horizontal roller and transmit it to the waste station. If the waste station is too late to process, it will not turn directly and transport the glass to the waste hopper 34 at the end, thereby improving the efficiency of waste processing. The overpass roller has two functions of turning and passing, and is mainly composed of two major components: the conveying roller and the belt transmission component. The conveying roller mainly has the function of longitudinally conveying the glass, and the belt transmission component mainly has the function of transversely conveying the glass. The belt conveying component also has two lifting stations. After lifting, the belt receives the glass conveyed transversely. At this time, the glass transmitted in the longitudinal direction can also pass through the roller below the belt. After the belt component is lowered, the glass is longitudinally conveyed again, and the glass achieves 90-degree reversing transmission.

[0079] In one embodiment, the flap turning device 3 comprises:

[0080] A first film turning device roller 31, both ends of which are respectively connected to the conveying roller;

[0081] The flap-turning sun wheel is located below the flap-turning device roller, and the flap-turning sun wheel drives the flap-turning device roller to turn sideways;

[0082] A second film turning device roller 32, which is arranged on the side of the first film turning device roller and is arranged perpendicular to the first film turning device roller 31;

[0083] The second flipping device roller 32 receives the flipped and fallen photovoltaic glass;

[0084] The second film turning device roller 32 points to the corresponding film unloading station 6 .

[0085] Specifically, in order to achieve a better conveying effect, the above-mentioned flapping device 3 is arranged at intervals on the conveying roller 4 in this embodiment. Specifically, the conveying roller 4 is a long strip roller, which is used to drive the photovoltaic glass to move, and multiple groups of first flapping device rollers 31 are arranged at intervals on the conveying roller 4. When the photovoltaic glass is driven by the roller to move to the first flapping device roller 31 at the corresponding position, the first flapping device roller 31 is driven by the flapping sun gear below to flip to the side, so that the photovoltaic glass falls onto the second flapping device roller 32 on the side, and the second flapping device roller 32 conveys the photovoltaic glass to the lower sheet station 6 in the vertical direction for subsequent processing, such as packaging, return cleaning, etc.

[0086] Among them, the conveying roller 4 includes an acceleration roller first arranged behind the detection roller 3. The acceleration roller can actively change the transfer speed according to the current amount of photovoltaic glass on the overall roller, thereby adjusting the overall production rhythm.

[0087] It also includes a multi-section transition roller, which is spaced apart from the first flipping device roller 31 to form a complete roller. The roller is mainly composed of a roller, an equipment frame, a bevel gear transmission system, and a plurality of transmission motors.

[0088] In one embodiment, the film turning device 3 further includes a film unloading robot 33 and a plurality of film unloading stations 6;

[0089] The unloading robot 33 is arranged behind the second film turning roller 32 and grabs the photovoltaic glass;

[0090] The unloading robot 33 transfers the photovoltaic glass to the unloading station 6.

[0091] Specifically, in order to improve the efficiency of laying and discharging photovoltaic glass, in this embodiment, multiple, for example, two unloading stations 6 are set behind each set of flipping devices 3 to process the input photovoltaic glass at the same time. In order to realize the input of multiple unloading stations 6, an unloading manipulator 33 is also set, which mainly includes a mechanical arm and a suction cup or a clamping device. When the second flipping device roller 32 receives and transports the photovoltaic glass, it can be grasped by the unloading manipulator 33 and moved to different unloading stations 6 in sequence. An offline paper laying machine is also set at the position of the unloading station 6. The offline paper laying machine includes a paper roll conveying system, a paper traction system and a stacking machine. When the unloading manipulator 33 grabs a photovoltaic glass and puts it on the stacking machine, the paper traction system controls the paper roll conveying system to unwind, and the paper roll is placed above the photovoltaic glass, and then the stacking machine descends to receive the new photovoltaic glass.

[0092] The unloading station 6 also includes:

[0093] The sheet discharging roller is connected to the discharge port of the stacking machine, and the sheet discharging roller transports the photovoltaic glass to the outside.

[0094] Among them, the sheet discharge roller is a chain roller with a tray, which receives the paper-covered photovoltaic glass output from the discharge port of the stacking machine and then transports it to the conveyor vehicle 62 at the rear.

[0095] In one embodiment, Figure 2 As shown, the sheet-loading stations 6 are arranged in the same row;

[0096] A conveying track 61 is provided in the discharging direction of the lower sheet station 6, and a conveying vehicle 62 is provided on the conveying track 61;

[0097] A lift 7 is provided on the side of the conveying track 61 away from the unloading station 6;

[0098] The conveyor 62 receives the photovoltaic glass outputted from the unloading station 6, and transports the photovoltaic glass to the elevator 7;

[0099] The elevator 7 transports the photovoltaic glass to the packaging floor;

[0100] The packaging conveying robot 8A on the packaging floor receives the photovoltaic glass from the plurality of elevators and puts it into the automatic packaging machine 8 for packaging;

[0101] The plurality of elevators 7 are arranged in a line, and the sheet loading route of the automatic packaging machine is vertically arranged relative to the elevators.

[0102] Specifically, in order to achieve a better conveying effect, in the present embodiment, a linear arrangement is set for different types of unloading stations 6, and parallel conveying tracks 61 are set. Two reciprocating conveying vehicles 62 are arranged on the conveying track 61. A lift 7 is set on the side of the conveying track 61 away from the unloading station 6, and the position of the lift 7 is determined according to the elevator shaft position layout of the workshop. When the stacking machine on the corresponding unloading station 6 is full, the conveying vehicle 62 is controlled by a signal to move to the corresponding unloading station 6, and then receives the photovoltaic glass output by the unloading roller. The conveying vehicle 62 transfers the full stack of glass to the lift 7, and then the lift 7 is transferred to the first floor. Avoidance stations are set at both ends of the conveying track, which are used to put one of the conveying vehicles 62 into the avoidance station to avoid interference between the two vehicles when the production rhythm is fast.

[0103] The conveyor 62 is mainly composed of a rail shuttle system, a chain transmission system, a frame, and a control box; the empty pallet buffer station is mainly composed of a frame and a chain transmission roller; the waste sheet station is similar to the empty pallet station, and is mainly used to cooperate with the horizontal stacker to stack waste sheets;

[0104] The elevator 7 is used for lifting and transferring finished photovoltaic glass, waste products, and empty pallets between the first and second floors; it is mainly composed of a lifting system, a rack, and a chain drive roller. In order to improve continuous production efficiency, the downward process of the elevator 7 is to transport the photovoltaic glass on the pallet to the first floor, and the upward process is that the elevator 7 transfers the empty pallet from the first floor to the second floor, and then docks with the conveyor 62, which transports the empty pallet to the corresponding unloading station 6.

[0105] In order to achieve a better structural layout, the present embodiment chooses to arrange multiple cleaning lines on the second floor and set up an automatic baler 8 on the first floor. Specifically, a plurality of the above-mentioned cleaning lines are arranged in the workshop on the second floor, and the elevators 7 of the cleaning lines are arranged in the same row, such as four elevators arranged in a line. The feeding and conveying direction of the automatic baler 8 is perpendicular to the arrangement direction of the elevator 7. A packaging and conveying robot 8A is assigned to the two elevators 7, which is used to receive the photovoltaic glass pallets output by the elevator 7 and send them to the packaging upper device 8B of the automatic baler 8. The automatic baler 8 is used for packaging and then output through the packaging lower device 8C and sent to the finished product warehouse 8D. The above layout can effectively solve the automated connection between deep processing and packaging on one or two floors, improve the transportation efficiency and reduce space occupancy.

[0106] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
