Description

Technical Field

[0001] The present invention relates to the technical field of glass production, and particularly to a production device and process for ultra-thin photovoltaic glass. Background Art

[0002] Photovoltaic glass is a special glass material, mainly used in solar photovoltaic power generation systems to protect solar panels and improve the light transmittance, thereby increasing the power generation efficiency of the entire photovoltaic system. It can also be applied to building-integrated photovoltaics and used as windows or curtain walls of buildings, which is both beautiful and can generate electricity.

[0003] Traditional photovoltaic glass is mostly produced by the float method. Molten glass liquid is poured onto molten tin to form a flat glass surface. In order to improve the light absorption efficiency of solar energy, ultra-thin photovoltaic glass is used. However, there are still some problems when using the float method to produce ultra-thin photovoltaic glass: Since the produced photovoltaic glass is relatively thin, it is necessary to accurately control the inflow amount when flowing into the tin bath and it needs to be stably laid flat on the surface of the tin bath in a relatively thin layer. Due to the thin glass liquid, if the temperature of the tin bath is uneven, some parts will cool faster and some parts will cool slower, which easily causes defects in the glass forming. And then it needs to be separately sent into an annealing chamber for glass annealing, and the process is relatively complex. Therefore, we propose a production device and process for ultra-thin photovoltaic glass to solve the above problems. Summary of the Invention

[0013] As a preferred technical solution of the present invention, the material discharging mechanism includes a material discharging inclined frame.

One end of the material discharging inclined frame is fixedly clamped in the material discharging through slot. A plurality of electric guide rollers evenly distributed are arranged at the inner bottom of the material discharging inclined frame, and the plurality of electric guide rollers are inclined.

[0014] The production process of a production device for ultra-thin photovoltaic glass includes the following steps:

[0015] Step 1: Place the tin liquid above the first L-shaped partition and the second L-shaped partition. By arranging a plurality of heating modules distributed in a rectangular array, the tin liquid can be temperature-controlled in a rectangular array, so as to precisely control the temperature of each area of the tin liquid. And through a plurality of traction mechanisms, the glass solution flowing on the upper surface of the tin liquid is traction-stretched, so that the glass solution can be made ultra-thin.

[0016] According to the thickness requirement of the photovoltaic glass, control the second telescopic cylinder to extend or contract, drive the control shaft rod to slide in the arc through slot, so as to control the bottom support inclined plate to rotate around the rotating shaft column, flexibly adjust the inclination angle of the bottom support inclined plate, and thus flexibly adjust the angle at which the glass solution is introduced into the tin liquid storage bin.

[0017] And by controlling the first telescopic cylinder to extend and contract to control the driving sleeve to slide in the arc adjustment slot, so as to control the pressing member to rotate around one of the pressing rollers, adjust the inclination angle of the pressing member, and thus flexibly adjust the length of the calendering spacing, so as to calender an ultra-thin glass solution with a suitable thickness according to the requirements.

[0018] Step 2: Import the mixed and melted glass solution into the upper surface of the tin liquid in the tin liquid storage bin at a certain inclination angle through the feeding through slot. During this period, control the second motor to drive the driving shaft to drive the second gear to rotate. Cooperating with the meshing connection of a plurality of differential gears and the first gear, drive the adjusting shaft to rotate slowly, drive the liquid control rod to rotate, and flexibly adjust the size of the liquid discharge port, so as to precisely control the amount of the glass solution flowing into the tin liquid storage bin, make the glass solution spread evenly on the upper surface of the tin liquid in an effective and precise amount, and form an ultra-thin glass solution layer on the upper surface of the tin liquid, so as to form ultra-thin glass in the subsequent process. With the synchronous traction of a plurality of traction mechanisms, an ultra-thin glass solution layer is formed on the upper surface of the tin liquid, and the temperature of the ultra-thin glass solution gradually stabilizes and decreases evenly when flowing on the upper surface of the tin liquid.

[0019] During this period, when the liquid level of the tin liquid in the tin liquid storage tank is relatively high, it is necessary to lower the liquid level. Control the opening of the two-way hydraulic pump, and introduce the tin liquid in the tin liquid storage tank into the storage cylinder for buffering through multiple connecting pipe clamps, multiple liquid guiding branch pipes, the liquid guiding main pipe, and the liquid guiding head, thereby lowering the liquid level of the tin liquid. When the liquid level of the tin liquid in the tin liquid storage tank is relatively low, it is necessary to raise the liquid level. Control the opening of the two-way hydraulic pump, and introduce the tin liquid buffered in the storage cylinder into the tin liquid storage tank through the liquid guiding head, the liquid guiding main pipe, multiple liquid guiding branch pipes, and multiple connecting pipe clamps, thereby raising the liquid level of the tin liquid. In this way, the liquid level of the tin liquid can be adjusted flexibly, so that the ultra-thin glass liquid can flow and extend on the upper surface of the tin liquid;

[0020] Step 3: Control the opening of the first motor to drive the corresponding bottom supporting roller to rotate. Cooperate with the meshing connection of the two transmission gears to drive the corresponding top pressing roller to rotate synchronously in the opposite direction, and then control the bottom supporting belt and the top pressing belt to transmit synchronously in the opposite direction. The ultra-thin glass liquid flows and transmits on the upper surface of the tin liquid in the first L-shaped partition. Passing between the bottom supporting belt and the top pressing belt, since the top pressing belt is inclined and cooperates with the synchronous reverse transmission of the bottom supporting belt and the top pressing belt, the front end of the ultra-thin glass liquid is gradually rolled and thinned again. The ultra-thin glass liquid flows more thinly on the upper surface of the tin liquid in the second L-shaped partition and continues to flow and transmit for cooling, thereby forming a thinner ultra-thin glass liquid, so as to form ultra-thin glass;

[0021] Step 4: The thinner ultra-thin glass liquid is introduced into the discharge inclined frame through the discharge through slot. Cooperate with the control to turn on multiple electric guide rollers, and discharge the thinner ultra-thin glass liquid obliquely out of the tin liquid storage tank for subsequent annealing treatment.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. By setting the material control mechanism, the angle of introducing the glass solution into the tin liquid storage tank can be adjusted flexibly, so as to better form ultra-thin glass on the upper surface of the tin liquid, and the size of the liquid discharge port can be adjusted flexibly, which is convenient for accurately controlling the amount of the glass solution flowing into the tin liquid storage tank, so that the glass solution is evenly spread on the upper surface of the tin liquid in an effective and accurate amount, and form a layer of ultra-thin glass liquid on the upper surface of the tin liquid, so as to form ultra-thin glass subsequently.

[0024] 2. By setting the pressure application mechanism, the front end of the ultra-thin glass liquid can be gradually rolled and thinned again, so that the ultra-thin glass liquid flows more thinly on the upper surface of the tin liquid in the second L-shaped partition and continues to flow and transmit for cooling, thereby forming a thinner ultra-thin glass liquid, so as to form ultra-thin glass.

[0025] 3. By setting the pressure application mechanism, the length of the rolling gap can be adjusted flexibly, so as to roll out ultra-thin glass liquid with a suitable thinness according to requirements, and improve the flexibility of the whole device.

[0026] 4. By setting up a liquid control mechanism, the liquid level position of the tin bath can be flexibly adjusted so that the ultra-thin glass liquid can flow and spread on the upper surface of the tin bath. BRIEF DESCRIPTION OF THE DRAWINGS

Temperature control elements are provided on both the first L-shaped partition 21 and the second L-shaped partition 22. The temperature control element includes a plurality of heating modules 23 distributed in a rectangular array. The heating modules 23 are fixedly installed on the corresponding first L-shaped partition 21 and second L-shaped partition 22. By setting a plurality of heating modules 23 distributed in a rectangular array, rectangular array temperature control can be performed on the tin liquid, so as to accurately control the temperature of each area of the tin liquid, which is convenient for accurately controlling the temperature when the glass solution flows on the upper surface of the tin liquid, and is convenient for the precise forming of ultra-thin glass. A plurality of traction mechanisms 24 are evenly distributed on the top of the tin bath 2. By setting a plurality of traction mechanisms 24, the glass solution flowing on the upper surface of the tin liquid is tractionally stretched to make the glass solution ultra-thin. A pressure-bearing mechanism 5 is provided between the first L-shaped partition 21 and the second L-shaped partition 22. A liquid control mechanism 6 is provided at the bottom of the first L-shaped partition 21 and the second L-shaped partition 22.

[0046] The material control mechanism 3 includes two symmetrically distributed material control side frames 31. The two material control side frames 31 are fixedly installed at the top of the first support 11. A bottom support inclined plate 32 is movably clamped at the bottom of the two material control side frames 31. An arc-shaped pressing plate 33 is fixedly clamped at the top of the two material control side frames 31.

A second gear 352 is fixedly installed on the outer side of the driving shaft 351. A plurality of differential gears 353 are provided between the first gear 35 and the second gear 352. The plurality of differential gears 353 are rotatably installed on the material control side frame 31. Adjacent two differential gears 353 are meshed and connected.

[0048] One end of the bottom support inclined plate 32 far from the rotating shaft column 321 is fixedly installed with a control shaft rod 322. An arc-shaped through groove 3221 corresponding to the control shaft rod 322 is formed on the material control side frame 31.

By controlling the second telescopic cylinder 361 to extend or contract, the control shaft rod 322 is driven to slide in the arc-shaped through groove 3221, so as to control the bottom support inclined plate 32 to rotate around the rotating shaft column 321, flexibly adjust the inclination angle of the bottom support inclined plate 32, and thus flexibly adjust the angle of the glass solution introduced into the tin bath 2, so as to better form an ultra-thin glass on the upper surface of the tin bath.

[0049] The pressure application mechanism 5 includes a bottom support member 51 and a top pressure member 52. The top pressure member 52 is located above the bottom support member 51. The bottom support member 51 includes two symmetrically distributed bottom support rollers 511. The two bottom support rollers 511 are rotatably installed on the tin bath 2. A bottom support belt 512 is movably sleeved outside the two bottom support rollers 511. The bottom support belt 512 is horizontally arranged. The top pressure member 52 includes two symmetrically distributed top pressure rollers 521. A top pressure belt 522 is movably sleeved outside the two top pressure rollers 521. The top pressure belt 522 is inclined. One of the top pressure rollers 521 is rotatably installed on the tin bath 2. The ends of the other top pressure roller 521 are rotatably sleeved with drive sleeves 55. Shielding frames 551 are integrally formed at the opposite ends of the drive sleeves 55. Transmission gears 53 are fixedly installed at the ends of the bottom support rollers 511 and the top pressure rollers 521 at the position away from the drive sleeves 55. The two transmission gears 53 are meshed and connected. The distance between the bottom support belt 512 and the top pressure belt 522 at the position away from the transmission gears 53 of the bottom support member 51 and the top pressure member 52 is set as the calendering distance. A first motor 54 is provided at the end of the bottom support roller 511 at the position close to the drive sleeve 55. The first motor 54 is fixedly installed outside the tin bath 2. The drive end of the first motor 54 and the end of the corresponding bottom support roller 511 are fixedly installed. By controlling the first motor 54 to start and drive the corresponding bottom support roller 511 to rotate, and cooperating with the meshing connection of the two transmission gears 53, the corresponding top pressure roller 521 is driven to rotate synchronously in the reverse direction. Furthermore, the bottom support belt 512 and the top pressure belt 522 are controlled to transmit synchronously in the reverse direction. The ultra-thin glass liquid flows and transmits on the upper surface of the tin liquid in the first L-shaped partition 21, passes between the bottom support belt 512 and the top pressure belt 522. Since the top pressure belt 522 is inclined and cooperates with the synchronous reverse transmission of the bottom support belt 512 and the top pressure belt 522, the front end of the ultra-thin glass liquid is gradually calendered and thinned again by the bottom support belt 512 and the top pressure belt 522, so that the ultra-thin glass liquid flows more thinly on the upper surface of the tin liquid in the second L-shaped partition 22 and continues to flow and transmit for cooling, thereby forming a thinner ultra-thin glass liquid to facilitate the formation of ultra-thin glass;

[0050] An arc-shaped adjustment groove 203 is provided on one side of the tin bath 2 close to the drive sleeve 55. The drive sleeve 55 is movably clamped in the corresponding arc-shaped adjustment groove 203. The drive sleeve 55 can slide in the arc-shaped adjustment groove 203. The shielding frame 551 shields the arc-shaped adjustment groove 203. When the drive sleeve 55 slides in the arc-shaped adjustment groove 203, the shielding frame 551 always shields the arc-shaped adjustment groove 203 to prevent the tin liquid from overflowing through the arc-shaped adjustment groove 203. A shielding groove 204 corresponding to the shielding frame 551 is provided at the inner end of the arc-shaped adjustment groove 203. The shielding frame 551 is movably clamped in the corresponding shielding groove 204.

[0054] The production process of a production device for ultra-thin photovoltaic glass includes the following steps:

[0055] Step 1: Place the tin liquid above the first L-shaped partition 21 and the second L-shaped partition 22. By arranging a plurality of heating modules 23 distributed in a rectangular array, the tin liquid can be temperature-controlled in a rectangular array, so as to accurately control the temperature of each area of the tin liquid. And through a plurality of traction mechanisms 24, the glass solution flowing on the upper surface of the tin liquid is traction-stretched, so that the glass solution becomes ultra-thin.

[0056] According to the thickness requirement of the photovoltaic glass, control the second telescopic cylinder 361 to extend or contract, drive the control shaft rod 322 to slide in the arc-shaped through groove 3221, so as to control the bottom support inclined plate 32 to rotate around the rotating shaft column 321, flexibly adjust the inclination angle of the bottom support inclined plate 32, and thus flexibly adjust the angle of the glass solution introduced into the tin bath 2;

[0057] And by controlling the first telescopic cylinder 561 to extend and contract, control the driving sleeve 55 to slide in the arc-shaped adjustment groove 203, so as to control the pressing member 52 to rotate around one of the pressing rollers 521, adjust the inclination angle of the pressing member 52, and thus flexibly adjust the length of the calendering spacing, so as to calender out ultra-thin glass liquid with appropriate thickness according to requirements;

[0058] Step 2: Introduce the mixed and melted glass solution into the upper surface of the tin liquid in the tin bath 2 at a certain inclination angle through the feeding through groove 201. During this period, control the second motor 354 to start, drive the driving shaft 351 to drive the second gear 352 to rotate, cooperate with the meshing connection of multiple differential gears 353 and the first gear 35, drive the regulating shaft 341 to rotate slowly, drive the liquid control rod 34 to rotate, and flexibly adjust the size of the liquid discharge port, so as to accurately control the amount of the glass solution flowing into the tin bath 2, make the glass solution spread evenly on the upper surface of the tin liquid in an effective and accurate amount, and form a layer of ultra-thin glass liquid on the upper surface of the tin liquid, so as to form ultra-thin glass in the subsequent process. With the synchronous traction of multiple traction mechanisms 24, a layer of ultra-thin glass liquid is formed on the upper surface of the tin liquid, and the temperature of the ultra-thin glass liquid gradually and stably decreases evenly when flowing on the upper surface of the tin liquid;

[0059] During this period, when the liquid level of the tin liquid in the tin bath 2 is relatively high, it is necessary to lower the liquid level position. Control the two-way hydraulic pump 62 to start, and introduce the tin liquid in the tin bath 2 into the storage cylinder 61 for caching through multiple connecting pipes 632, multiple liquid guide branch pipes 631, the liquid guide main pipe 63 and the liquid guide head 611, so as to lower the liquid level position of the tin liquid. When the liquid level of the tin liquid in the tin bath 2 is relatively low, it is necessary to raise the liquid level position. Control the two-way hydraulic pump 62 to start, and introduce the tin liquid cached in the storage cylinder 61 into the tin bath 2 through the liquid guide head 611, the liquid guide main pipe 63, multiple liquid guide branch pipes 631 and multiple connecting pipes 632, so as to raise the liquid level position of the tin liquid, and thus flexibly adjust the liquid level position of the tin liquid, so that the ultra-thin glass liquid can flow and extend on the upper surface of the tin liquid;

[0060] Step 3: Control the first motor 54 to start driving the corresponding bottom support roller 511 to rotate. With the meshing connection of the two transmission gears 53, drive the corresponding top pressure roller 521 to rotate synchronously in the opposite direction, and then control the bottom support belt 512 and the top pressure belt 522 to transmit synchronously in the opposite direction. The ultra-thin glass liquid flows and transmits on the upper surface of the tin liquid in the first L-shaped partition plate 21, passing between the bottom support belt 512 and the top pressure belt 522. Since the top pressure belt 522 is inclined and in cooperation with the synchronous reverse transmission of the bottom support belt 512 and the top pressure belt 522, the bottom support belt 512 and the top pressure belt 522 gradually roll and thin the front end of the ultra-thin glass liquid again, making the ultra-thin glass liquid flow more thinly on the upper surface of the tin liquid in the second L-shaped partition plate 22 and continue to flow and transmit for cooling, thereby forming a thinner ultra-thin glass liquid to facilitate the formation of ultra-thin glass;

[0061] Step 4: The thinner ultra-thin glass liquid is introduced into the discharge inclined frame 41 through the discharge through groove 202. With the control to start multiple electric guide rollers 42, the thinner ultra-thin glass liquid is discharged obliquely upward from the tin liquid tank 2 for subsequent annealing treatment.

A production process using the production device for the ultra-thin photovoltaic glass described in claim 9, characterized in that, It includes the following steps: Step 1: Place the tin liquid above the first L-shaped partition plate (21) and the second L-shaped partition plate (22). By setting a plurality of heating modules (23) distributed in a rectangular array, the temperature of the tin liquid can be controlled in a rectangular array, so as to accurately control the temperature of each area of the tin liquid. And through a plurality of traction mechanisms (24), the glass solution flowing on the upper surface of the tin liquid is tractionally stretched, so that the glass solution is made ultrathin. According to the thinness requirement of the photovoltaic glass, control the second telescopic cylinder (361) to extend or contract, drive the control shaft rod (322) to slide in the arc-shaped through groove (3221), so as to control the bottom support inclined plate (32) to rotate around the rotating shaft column (321), and flexibly adjust the inclination angle of the bottom support inclined plate (32), so as to flexibly adjust the angle of the glass solution introduced into the tin liquid storage bin (2). And by controlling the first telescopic cylinder (561) to extend and contract, control the driving sleeve (55) to slide in the arc-shaped adjustment groove (203), so as to control the top pressing member (52) to rotate around one of the top pressing rollers (521), adjust the inclination angle of the top pressing member (52), so as to flexibly adjust the length of the calendering spacing, so as to calender an ultrathin glass liquid with a suitable thinness according to the requirements. Step 2: Introduce the mixed and melted glass solution onto the upper surface of the tin liquid in the tin liquid storage tank (2) through the feeding trough (201) at a certain inclined angle. During this period, control the second motor (354) to drive the drive shaft (351) to drive the second gear (352) to rotate. Cooperating with the meshing connection of multiple differential gears (353) and the first gear (35), drive the adjusting shaft (341) to rotate slowly, drive the liquid control rod (34) to rotate, and flexibly adjust the size of the liquid discharge port, so as to accurately control the amount of the glass solution flowing into the tin liquid storage tank (2), make the glass solution spread evenly on the upper surface of the tin liquid in an effective and accurate amount, and form an ultra-thin glass liquid layer on the upper surface of the tin liquid, so as to form ultra-thin glass subsequently. With the synchronous traction of multiple traction mechanisms (24), an ultra-thin glass liquid layer is formed on the upper surface of the tin liquid, and the temperature of the ultra-thin glass liquid gradually and evenly decreases steadily when it flows on the upper surface of the tin liquid; During this period, when the liquid level of the tin liquid in the tin liquid storage tank (2) is relatively high, it is necessary to lower the liquid level position. Control the bidirectional hydraulic pump (62) to open, and introduce the tin liquid in the tin liquid storage tank (2) into the storage cylinder (61) for buffering through multiple connecting pipes (632), multiple liquid guiding branch pipes (631), the liquid guiding main pipe (63), and the liquid guiding head (611), so as to lower the liquid level position of the tin liquid. When the liquid level of the tin liquid in the tin liquid storage tank (2) is relatively low, it is necessary to raise the liquid level position. Control the bidirectional hydraulic pump (62) to open, and introduce the buffered tin liquid in the storage cylinder (61) into the tin liquid storage tank (2) through the liquid guiding head (611), the liquid guiding main pipe (63), multiple liquid guiding branch pipes (631), and multiple connecting pipes (632), so as to raise the liquid level position of the tin liquid, and thus flexibly adjust the liquid level position of the tin liquid to facilitate the flow and extension of the ultra-thin glass liquid on the upper surface of the tin liquid; Step 3: Control the first motor (54) to drive the corresponding bottom support roller (511) to rotate.

The ultra-thin glass liquid flows and transmits on the upper surface of the tin liquid in the first L-shaped partition (21), passes between the bottom support belt (512) and the top pressing belt (522). Since the top pressing belt (522) is inclined and cooperates with the synchronous reverse transmission of the bottom support belt (512) and the top pressing belt (522), the front end of the ultra-thin glass liquid is gradually rolled and thinned again by the bottom support belt (512) and the top pressing belt (522), so that the ultra-thin glass liquid flows thinner on the upper surface of the tin liquid in the second L-shaped partition (22) and continues to flow and transmit for cooling, thereby forming a thinner ultra-thin glass liquid to facilitate the formation of ultra-thin glass; Step 4: The thinner ultra-thin glass liquid is introduced into the discharge inclined frame (41) through the discharge trough (202). Cooperating with the control of multiple electric guide rollers (42) to open, discharge the thinner ultra-thin glass liquid obliquely upward from the tin liquid storage tank (2) for subsequent annealing treatment.
