Description

Technical Field

[0001] The present application relates to the field of photovoltaic glass production, and in particular to a material temporary storage device for a photovoltaic glass production line. Background Art

[0002] Photovoltaic glass, also known as "photoelectric glass", is a special glass that uses solar radiation to generate electricity and has relevant current lead-out devices and cables. Photovoltaic glass is composed of glass sheets, solar cells, films, back glass, special metal wires, etc. It is widely used, such as solar smart windows, solar pavilions, photovoltaic glass building roofs, and photovoltaic glass curtain walls.

[0003] In the process of producing glass sheets and back glass, a specific production line is usually used for semi-automatic or automatic production. Semi-automatic production lines or automatic production lines are composed of several workstations. When a product problem occurs in one of the workstations, it is easy to cause the processing of the two adjacent workstations to be affected. If the workstation with the product problem stops alone, it will cause the products of other workstations to break or pile up. If the entire production line is stopped for adjustment, the overall production efficiency will be seriously reduced. Utility Model Content

[0004] In order to improve the problem of low production efficiency caused by a problem in one workstation on a production line requiring all workstations to stop, the present application provides a material temporary storage device for a photovoltaic glass production line.

[0005] The present application provides a material temporary storage device for a photovoltaic glass production line, which adopts the following technical solution:

[0006] A material temporary storage device for a photovoltaic glass production line is arranged between two adjacent workstations on the production line, and comprises a frame, wherein a plurality of rollers for supporting and conveying glass are arranged at intervals in the horizontal direction in the inner middle part of the frame; a plurality of lifting mechanisms are arranged in the frame, and the lifting mechanisms comprise a driving unit and a plurality of lifting rods, wherein the lifting rods are located below the glass, and the driving unit is located outside the glass, and the driving unit drives the plurality of lifting rods to sequentially pass through the planes where the plurality of rollers are located in the vertical direction, and the lifting rods are used to lift the glass.

[0007] By adopting the above technical solution, several driving units drive the lifting rod at the same time, so that the lifting rod moves from the bottom of the roller to the top of the roller, and in this process, the glass on the roller can be lifted and moved away from the roller. In this way, when the workstation located at the rear side of the frame stops due to problems, the workstation located at the front side of the frame can continue production and temporarily store the glass through several lifting rods, without the need to stop and wait synchronously, thereby effectively improving production efficiency.

[0008] Optionally, the lifting rods of two adjacent lifting mechanisms correspond to each other one by one, and the length of the lifting rods is greater than the width of the glass.

[0009] By adopting the above technical solution, under the drive of several driving units, different lifting rods in different lifting mechanisms can move synchronously, ensuring that each lifting mechanism has a lifting rod for lifting the glass.

[0010] Optionally, the driving unit includes a pair of transmission chain groups arranged on both sides of the lifting rod, the transmission chain group includes a pair of sprockets arranged at intervals in the vertical direction and a chain tensioned on the outside of the pair of sprockets, the two sprockets at the same height are connected by a first transmission rod, and the two adjacent driving units are connected by a second transmission rod. The frame is also provided with an electric motor, and the motor drives any one of the sprockets to rotate; a plurality of lifting rods in one of the lifting mechanisms are fixedly connected to the chain of the corresponding driving unit.

[0011] By adopting the above technical solution, under the driving action of the motor and the transmission action of the first transmission rod and the second transmission rod, all the sprockets can rotate simultaneously, so that all the transmission chain groups can drive the lifting rods simultaneously and synchronously, ensuring that the lifting rods can reliably lift and lift the glass on the rollers.

[0012] Optionally, one sprocket of the transmission chain group is located above the roller, and another sprocket of the transmission chain group is located below the roller.

[0013] By adopting the above technical solution, it is ensured that under the drive of the transmission chain group, the lifting rod can pass through the plane where the plurality of rollers are located and realize the lifting of the glass.

[0014] Optionally, a dust removal mechanism is provided under each of the rollers, and the dust removal mechanism includes a water tank and a negative pressure tank. The negative pressure tank is provided at the bottom of the rollers, and the bottom of the negative pressure tank is provided with a plurality of exhaust pipes connected to the water tank. An exhaust pump is provided on the exhaust pipe, and one end of the exhaust pipe is located in the water tank and is immersed below the water surface of the water tank.

[0015] By adopting the above technical solution, the vacuum pump will be activated to draw the air in the negative pressure tank into the water tank through the vacuum pipe, thereby forming a negative pressure in the negative pressure tank. In this way, during the flow of air, the dust on the surface of the roller will be adsorbed, thereby preventing the dust from scratching the glass sliding on the roller; one end of the vacuum pipe in the water tank is immersed below the water surface, which can play the role of air washing, so that the dust is trapped in the water tank to avoid secondary pollution.

[0016] Optionally, the negative pressure tank is fixed on the frame, a tank cover of the negative pressure tank covers the bottom of the roller, and a plurality of the exhaust pipes are arranged at intervals along the length direction of the negative pressure tank.

[0017] By adopting the above technical solution, the notch of the negative pressure groove is close to the bottom of the roller, so that the flow rate of air when being sucked into the negative pressure groove from the outside can be maximized, thereby improving the dust removal effect on the roller; a plurality of exhaust pipes are arranged at intervals at the bottom of the negative pressure groove, which can improve the negative pressure effect in the negative pressure groove.

[0018] Optionally, a brush strip is provided at the notch of the negative pressure groove, and the brush strip is detachably connected to the inner side of the negative pressure groove by bolts, and the brush strip is used to brush the surface of the roller.

[0019] By adopting the above technical solution, the brush strip is in direct contact with the roller, so that during the rolling of the roller, the dust adhering to the surface of the roller is swept away and then absorbed by the negative pressure groove, thereby improving the cleaning effect of the roller and effectively preventing the dust from causing wear of the glass.

[0020] Optionally, a gate valve for controlling the water level of the water tank is provided on the side wall of the water tank, and the gate valve is in a normally closed state; an exhaust pipe is provided on the upper part of the water tank, and an air blowing head connected to the exhaust pipe is provided on the top of the negative pressure tank, and the air blowing head blows air toward the end of the roller.

[0021] By adopting the above technical scheme, the gate valve can be used to replace the water in the water tank after it is opened, ensuring that the water in the water tank can reliably intercept dust in the air and play a role in washing air; after the air is discharged from below the water surface, it will be transported to the air blowing head through the exhaust pipe and then blown out through the air blowing head. In this way, the airflow blown out by the air blowing head can be used to promote the rolling of the roller.

[0022] Optionally, a plurality of blades are provided at the end of the supporting roller, the blades are arranged in a circle, the blades are located on the outside of the glass, and the air blowing head blows air toward the blades.

[0023] By adopting the above technical solution, the airflow blown out by the air blowing head acts on the blades, which can improve the driving effect on the roller, thereby offsetting the resistance of the brush strip to the rotation of the roller and ensuring that the glass can slide smoothly on the roller.

[0024] In summary, this application has the following beneficial effects:

[0025] 1. The lifting rods of several lifting mechanisms correspond to each other and move synchronously, so that the lifting rods of different lifting mechanisms can move upward from the bottom of the roller and lift the glass on the roller. In this way, the glass is temporarily stored on the frame, and the workstations on both sides of the frame can be in different states, so that all workstations on the production line will not stop synchronously due to the parking of a certain workstation, which effectively improves production efficiency.

[0026] 2. The negative pressure suction effect of the negative pressure tank combined with the scraping effect of the brush bar can reliably remove the dust adhering to the surface of the roller, thereby preventing the friction between the dust and the glass from affecting the quality of the glass.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] Figure 1 is a schematic stereogram of the present application, Figure 2This is a reference diagram of the use status of this application. A material temporary storage device for a photovoltaic glass production line is arranged between two adjacent workstations on the production line, including a frame 1, a plurality of rollers 3 are arranged in the middle of the frame 1, and the plurality of rollers 3 are arranged at intervals in the horizontal direction, that is, the plurality of rollers 3 are arranged in the same plane, so that the glass 2 produced on the production line can slide on the rollers 3 in the horizontal direction. A plurality of lifting mechanisms 4 are also arranged in the frame 1, and the plurality of lifting mechanisms 4 are used to lift the glass 2 to the top of the rollers 3 for temporary storage.

[0035] Figure 3 is a schematic three-dimensional diagram of the lifting mechanism. Figure 3 Combined with Figure 2 Each lifting mechanism 4 includes a driving unit 41 and a plurality of lifting rods 42. The driving unit 41 includes a pair of transmission chain groups. Each transmission chain group includes two sprockets 411 and a chain 412. The two sprockets 411 are installed on the frame 1 through a rotating seat, and one sprocket 411 is located above the roller 3 and the other sprocket 411 is located below the roller 3. The chain 412 is adaptively wound around the outside of the two sprockets 411 and is in a tensioned state. The two transmission chain groups in one driving unit 41 are symmetrically arranged on both sides of the glass 2, and the length of the lifting rod 42 is greater than the width of the glass 2, ensuring that the driving unit 41 will not interfere with the glass 2 during the operation. At the same time, the two sprockets 411 located at the same height in the two transmission chain groups are connected by the first transmission rod 413, that is, the two transmission chain groups are connected by the two first transmission rods 413 and realize synchronous rotation. Further, the transmission chain groups of the driving units 41 of the two adjacent lifting mechanisms 4 are connected by the second transmission rod 414 and realize synchronous rotation. Specifically, a gear group can be arranged between the second transmission rod 414 and the sprocket 411. After the motor 415 is arranged on the frame 1, the simultaneous rotation of all the sprockets 411 can be realized by the drive of the motor 415, and the synchronous rotation of all the transmission chain groups is realized.

[0036] join Figure 2, the lifting rods 42 in each lifting mechanism 4 are arranged between a pair of transmission chain groups, that is, one end of the lifting rod 42 is connected to the chain 412 of one transmission chain group, and the other end of the lifting rod 42 is connected to the chain 412 of another transmission chain group, and the lifting rods 42 are arranged at intervals in the vertical direction. The lifting rods 42 of two adjacent lifting mechanisms 4 correspond to each other and are all located below the glass 2. In this way, when the motor 415 is running, the lifting rod 42 at the top of each lifting mechanism 4 will simultaneously pass through the plane where the rollers 3 are located, so that the glass 2 on the rollers 3 is lifted up. At this time, since the lifting rods 42 are arranged at intervals, the new glass 2 will slide onto the several rollers 3 again, and then, the lifting rod 42 of each lifting mechanism 4 located under the new glass 2 will simultaneously pass through the plane where the several rollers 3 are located and realize the lifting of the new glass 2. In this way, several lifting rods 42 can pass through the rollers 3 in sequence to realize the lifting of several glasses 2. The lifted glass 2 can be temporarily stored in the frame 1, so as not to affect the normal production of the workstation on the front side of the frame 1, while leaving time for the workstation on the back side of the frame 1 to deal with abnormal situations, thereby effectively improving the production efficiency of the glass 2.

[0037] Figure 4 It is a schematic three-dimensional diagram of the dust removal mechanism. Figure 5 yes Figure 4 A schematic diagram of the enlarged structure at A in the middle. Figure 4 and Figure 5 A dust removal mechanism 5 is provided under each roller 3, and the dust removal mechanism 5 includes a water tank 51 and a negative pressure groove 52. The negative pressure groove 52 extends along the length direction of the roller 3 and is fixed on the frame 1. The notch of the negative pressure groove 52 is close to the bottom of the roller 3. A plurality of exhaust pipes 53 are provided at the bottom of the negative pressure groove 52. One end of the exhaust pipe 53 is connected with the negative pressure groove 52, and the other end of the exhaust pipe 53 is connected with the water tank 51. The water tank 51 is filled with water, and the other end of the exhaust pipe 53 extends below the water surface of the water body (the exhaust pipe 53 may include a main pipe and multiple branch pipes, and the multiple branch pipes converge at the end of the main pipe, the branch pipe is connected with the negative pressure groove 52, and the main pipe is connected with the water tank 51). An air pump 54 is provided on the air extraction pipe 53, and the air extraction pump 54 is fixed on the top of the water tank 51. When the air extraction pump 54 starts to work, the air in the negative pressure tank 52 can be sucked into the water tank 51, so that the notch of the negative pressure tank 52 is in a negative pressure state. A plurality of air extraction pipes 53 are arranged at intervals at the bottom of the negative pressure tank 52, which can improve the air extraction effect of the air extraction pump 54 on the negative pressure tank 52.

[0038] See also Figure 5A pair of brush strips 521 are symmetrically arranged at the notch of the negative pressure groove 52. The brush strips 521 are in contact with the bottom of the roller 3 and are detachably fixed to the inner side of the negative pressure groove 52 by bolts 522. When the glass 2 slides on the roller 3, the roller 3 will also rotate around itself. At this time, mutual friction will be generated between the brush strips 521 and the roller 3, so that the brush strips 521 can brush away the dust adhering to the surface of the roller 3. The brushed dust will float in the negative pressure groove 52 and enter the water body of the water tank 51 with the flowing air, while the dust mixed in the air will be trapped in the water body of the water tank 51 and will no longer flow to the outside of the water tank 51 with the air, thus forming a washing effect, effectively avoiding the secondary pollution of the roller 3 by dust. Under the scraping action of the brush strips 521, the surface of the roller 3 can be kept clean, thereby preventing the dust on the roller 3 from scratching the glass 2 when the glass 2 slides on the roller 3, thereby improving the finished product quality of the glass 2 to a certain extent.

[0039] See also Figure 4 A gate valve 511 for controlling the water level of the water tank 51 is provided on the side wall of the water tank 51. When a lot of dust is trapped in the water tank 51, the valve can be opened and the water in the water tank 51 can be replaced to ensure that the water has a reliable cleaning effect on the air. When the air pump 54 is in operation, the valve is in a normally closed state. At the same time, an exhaust pipe 512 is provided on the upper part of the water tank 51. The air is discharged to the outside through the exhaust pipe 512 after being cleaned by the water.

[0040] See also Figure 2 and Figure 5 An air blowing head 523 is provided at the top of the negative pressure groove 52. The air blowing head 523 is located at the end of the negative pressure groove 52 and is connected to the exhaust pipe 512. A plurality of blades 30 are provided at intervals along the circumferential direction at the end of the roller 3. The plurality of blades 30 are located on the outside of the glass 2. The air outlet of the air blowing head 523 faces the blades 30. When the air is discharged from the air outlet of the air blowing head 523, it will blow toward the blades 30, so that the blades 30 rotate, thereby promoting the rotation of the roller 3. In this way, the friction between the brush strip 521 and the roller 3 can be offset, thereby ensuring that the glass 2 can slide smoothly on the roller 3.

[0041] During the production process, when the glass 2 at the station on the front side of the frame 1 is processed, it will first slide into the frame 1, that is, slide on the rollers 3 in the frame 1, and the dust removal mechanism 5 is always in working state during the sliding process of the glass 2, so as to ensure that dust that will wear the glass 2 will not adhere to the rollers 3. If the station on the rear side of the frame 1 is in normal working state, the glass 2 will not stay in the frame 1, but will slide directly into the station on the rear side of the frame 1 through the rollers 3, and the lifting mechanism 4 will also be in standby state. If the station on the rear side of the frame 1 is in a parking state due to production problems, the lifting mechanism 4 will start to work, and multiple pieces of glass 2 can be lifted in turn and temporarily stored in the frame 1, so as to leave time for the station on the rear side of the frame 1 to deal with production problems without affecting the normal production of the station on the front side of the frame 1, thereby effectively improving the overall production efficiency.

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