The present invention provides a solar photovoltaic film production apparatus 10, as shown in fig. 1, comprising: the melt adhesive die head 100, the cooling roller 200, the transmission device 300 and the vision inspection device 400. The melt adhesive die head 100 is arranged above the cooling roller 200, the transmission device 300 is arranged between the cooling roller 200 and the vision inspection device 400, and the cooling roller 200, the transmission device 300 and the vision inspection device 400 are connected through the photovoltaic film 20.
As shown in fig. 2, the visual inspection apparatus 400 includes: the light-emitting lamp 410, the first transmission roller 420 and the second transmission roller 430, the axis of the first transmission roller 420 and the axis of the second transmission roller 430 are parallel to each other, the light-emitting lamp 410 is arranged between the first transmission roller 420 and the second transmission roller 430, the photovoltaic film 20 sequentially passes through the first transmission roller 420 and the second transmission roller 430, and the light-emitting lamp 410 is positioned on one side of the photovoltaic film 20.
The present invention aims to solve the problem that it is difficult to find holes in the photovoltaic film 20 in time during the production process in the prior art, and the production process of the solar photovoltaic film production apparatus 10 is approximately as follows (please refer to fig. 1 and 2 together):
first, the molten raw material is ejected through the melt adhesive die head 100, which is ejected on the rotating cooling drum 200, and the molten raw material is rapidly cooled and solidified, and a thin film (i.e., the photovoltaic film 20) is formed on the cooling drum 200;
subsequently, the photovoltaic film 20 passes through the actuator 300 and is then transferred to the viewing device 400. When the visual inspection device 400 is located, the photovoltaic film 20 sequentially passes through the first transmission roller 420 and the second transmission roller 430, and the positions of the first transmission roller 420 and the second transmission roller 430 are staggered, so that the photovoltaic film 20 forms a "curtain", and the light-emitting lamp 410 is located at one side of the "curtain" (the left side of the photovoltaic film 20 as shown in fig. 1);
in operation, light from the light fixture 410 is directed onto a "curtain" formed by the photovoltaic film 20, and an observer stands on the other side of the "curtain" (the right side of the photovoltaic film 20 as viewed in FIG. 1). If there is a hole on the photovoltaic film 20, the light of the light-emitting lamp 410 can still pass through the hole even if the hole is smaller, so that an observer can intuitively and clearly find out whether there is a hole on the photovoltaic film 20 by observing whether the photovoltaic film 20 has a light-transmitting bright spot.
By means of the solar photovoltaic film production apparatus 10, an observer can quickly find a bright place and thus a hole position by looking at the photovoltaic film 20 only when in operation. Of course, to make the bright place more noticeable, the light emitted by the light emitting lamp 410 may be red; moreover, the observer can also be replaced by a prior art visual inspection camera.
Further, although the solar photovoltaic film production apparatus 10 can solve the technical problem that the holes are not easily found, due to the limitation of the production speed (the working speed of the melt adhesive die head 100 and the cooling roller 200 is constant), the photovoltaic film 20 needs a long time when passing through the first transmission roller 420 and the second transmission roller 430, and relatively speaking, the observer can quickly complete the hole finding work, which results in that the observer needs to wait for a long time, and the working efficiency is limited by the production speed and is lower. In order to solve the above-described problem of low working efficiency, in one embodiment, the solar photovoltaic film production apparatus 10 of the present invention is improved on the transmission 300.
Specifically, as shown in fig. 3, the transmission 300 includes: the input roller 310, the output roller 320, the frame body 330 and the lamination box 340, the lamination box 340 is located in the frame body 330, and input roller 310 movably locates lamination box 340 top, and photovoltaic membrane 20 passes through input roller 310, lamination box 340 and output roller 320 in proper order, and lamination box 340 is used for piling up the accumulation to photovoltaic membrane 20.
The principle is as follows: the photovoltaic film 20 produced from the cooling roll 200 enters the transmission 300 and is accumulated in the transmission 300; after accumulating to a certain extent, the photovoltaic film 20 passes through the inspection device 400 at a faster speed, so that the working efficiency of the inspection step can be further improved under the condition of not changing the production speed of the photovoltaic film 20.
In use, the photovoltaic film 20 passes through the input roll 310, the lamination box 340, and the output roll 320 in that order. In the accumulation phase, the input roller 310 rotates, while the output roller 320 does not rotate, and the photovoltaic film 20 falls into the lamination box 340 after passing through the input roller 310; in the process, the output roller 320 is reciprocally translated over the lamination box 340, thereby guiding the photovoltaic film 20 to take a layer-by-layer stacked state (as shown in fig. 3) after falling into the lamination box 340. After accumulating to some extent, the output roller 320 rotates to guide the photovoltaic film 20 out of the lamination box 340 quickly and into the inspection apparatus 400 of the next process.
It should be noted that, considering that the temperature of the photovoltaic film 20 just produced is relatively high, and the photovoltaic film is easily deformed when being strongly extruded or pulled, for this reason, when the photovoltaic film 20 is accumulated, the embodiment does not use a traditional winding and unwinding manner, but uses a layer-by-layer stacking manner to accumulate, so that the photovoltaic film 20 is more beneficial to heat dissipation, and the pulling force of the photovoltaic film during the accumulation process can be reduced.
On the basis of solving the problem of low working efficiency, in order to further enhance the heat dissipation capability of the photovoltaic film 20 during the accumulation process and reduce the contact friction between the multilayer photovoltaic films 20, in another embodiment, the transmission 300 of the present invention is specifically designed.
Specifically, as shown in fig. 4 and 5, the transmission 300 includes: the photovoltaic film 20 sequentially passes through the input roller 310, the lamination member 500, and the output roller 320, the frame body 330, and the lamination member 500 is used for stacking and accumulating the photovoltaic film 20.
As shown in fig. 4, the number of the laminated members 500 is two, and the two laminated members 500 are symmetrically disposed on the frame body 330. As shown in fig. 5 and 6, each laminated member 500 includes: the movable base 510, the synchronous belt 520, two synchronous wheels 530, two blanking frames 540, a plurality of positioning columns 550 and a plurality of supporting rods 501, wherein the movable base 510 is arranged on the rack body 330 in a lifting sliding manner, the two synchronous wheels 530 are arranged on the movable base 510, the synchronous belt 520 is wound on the synchronous wheels 530, the synchronous belt 520 is provided with a trough 521, the two blanking frames 540 are arranged on the movable base 510, the tail ends of the blanking frames 540 extend to the synchronous belt 520 (as shown in fig. 7), the plurality of supporting rods 501 are stacked and accommodated in the blanking frames 540, and the plurality of positioning columns 550 are arranged on two sides of the movable base 510.
Preferably, the input roller 310 is disposed above the stacking member 500, and two blanking frames 540 are respectively disposed on two sides of the input roller 310 (as shown in fig. 6), and two synchronizing wheels 530 respectively correspond to the two blanking frames 540.
In this embodiment, the positioning post 550 has magnetism, the supporting rod 501 is of a ferroalloy structure, and the positioning post 550 and the supporting rod 501 are attracted to each other. When the support rod 501 approaches the positioning post 550, the two will attract each other, and the support rod 501 will be attracted by the magnetic attraction force to adhere to the positioning post 550. Of course, the positioning column 550 may be made of iron alloy, and the supporting rod 501 may have magnetism, so long as the supporting rod 501 is adsorbed on the positioning column 550.
Moreover, the positioning post 550 is provided with a latch 551 (as shown in fig. 8), and an end of the support rod 501 is in latching engagement with the latch 551. The latch 551 is arranged to prevent the support rod 501 adsorbed on the positioning column 550 from sliding off, so that the support rod 501 is stably located at a certain height on the positioning column 550.
Principle of operation of the transmission 300: the photovoltaic film 20 enters the frame body 330 through the input roller 310, is stacked and accumulated by the stacking member 500, and finally leaves the frame body 330 through the output roller 320. Next, the specific working steps of the transmission 300 of the present embodiment will be explained with reference to the above-described structure:
in the initial state, the photovoltaic film 20 directly winds the input roller 310 and the output roller 320, and the photovoltaic film 20 forms a curtain in the frame body 330 (as shown in fig. 9); both of the stacking members 500 are positioned at a lower position of the frame body 330, and both of the stacking members 500 are maintained at the same horizontal plane, and the plurality of support rods 501 are accommodated in the blanking frame 540. (notably, both ends of the supporting bar 501 are respectively at the two stacking members 500.) when the synchronous wheel 530 drives the synchronous belt 520 to reciprocate, the trough 521 on the synchronous belt 520 reciprocates between the two synchronous wheels 530;
first, the synchronizing wheel 530 rotates forward, the trough 521 on the synchronizing belt 520 moves leftward, and when the trough 521 passes through the right blanking frame 540 as shown in fig. 9, the supporting rod 501 in the blanking frame 540 falls into the trough 521, so that the supporting rod 501 is taken out from the blanking frame 540. At this time, the trough 521 and the support rod 501 therein are on the right side of the photovoltaic film 20 "curtain";
subsequently, the synchronous belt 520 continues to drive the trough 521 on the synchronous belt 520 to move leftwards, and the trough 521 and the supporting rod 501 therein stir the photovoltaic film 20 leftwards; when the trough 521 passes the left-hand blanking frame 540 as shown in fig. 9, the support rods 501 of the blanking frame 540 do not fall into the trough 521 because the support rods 501 are already present in the trough 521. As the timing belt 520 moves, the chute 521 passes over the left blanking frame 540, which begins to rotate about the timing wheel 530, and the chute 521 gradually approaches the left positioning post 550. At this time, under the action of magnetic attraction, the supporting rod 501 is separated from the trough 521 and is adsorbed on the positioning column 550, and the photovoltaic film 20 is folded at the corner;
immediately after the two stacking members 500 are lifted a certain distance, the synchronizing wheel 530 is reversed, the trough 521 on the synchronizing belt 520 moves rightward (in the opposite direction), and when the trough 521 passes through the left blanking frame 540 as shown in fig. 9, the supporting rod 501 in the blanking frame 540 falls into the trough 521, i.e., the supporting rod 501 is removed. At this point, the trough 521 and the support rods 501 therein are to the left of the "curtain" of photovoltaic film 20. Subsequently, the trough 521 and the support bar 501 therein are moved rightward, thereby moving the support bar 501 to the right side of the laminated member 500; eventually, the support bar 501 will be attracted to the right hand post 550, similar to that described above. Thus, the support bar 501 is positioned on the right side of the frame body 330, and the support bar 501 is positioned higher than the previous support bar 501, where the photovoltaic film 20 is folded;
subsequently, the lamination member 500 continuously repeats the above operation, and the photovoltaic film 20 can be laminated and accumulated, and the state thereof after lamination is as shown in fig. 10. After accumulating to a certain extent, the output roller 320 can guide the photovoltaic film 20 to the vision inspection device 400 quickly.
It should be noted that the transmission 300 of the present embodiment has the following features:
first, lamination accumulation of the photovoltaic films 20 is achieved, and gaps exist between the multilayer photovoltaic films 20 (as shown in fig. 10). In this way, each layer of photovoltaic film 20 can be fully contacted with air, so that the overall heat dissipation capacity is improved; meanwhile, the multi-layer photovoltaic films 20 are not contacted and rubbed with each other, so that the abrasion is reduced;
secondly, compared with the layer-by-layer stacking mode without the supporting rods 501, after the supporting rods 501 are arranged, the supporting rods 501 have a lifting effect on the photovoltaic films 20 of each layer, and the photovoltaic films 20 at the lower layer only bear the self weight and do not need to bear the weight of the photovoltaic films 20 at the higher layer;
thirdly, the operation is convenient. When stacking and accumulating, the stacking member 500 sequentially folds the photovoltaic film 20 from bottom to top, which automatically completes the stacking operation; when the photovoltaic film 20 is taken away, the operator only needs to draw the support rods 501 from bottom to top in sequence according to the installation sequence, and the photovoltaic film 20 can be smoothly withdrawn from the frame body 330.
It should be noted that the photovoltaic film 20 only contacts the middle portion of the support rods 501, and does not cover both ends of the support rods 501. Thus, when the support rods 501 are adsorbed onto the positioning posts 550, the photovoltaic film 20 is not clamped by the support rods 501 and the positioning posts 550. This is designed to prevent the photovoltaic film 20 from being squeezed or pulled as much as possible, and to prevent holes or wrinkles from occurring in the fragile photovoltaic film 20.
In one embodiment, a sliding block 511 (as shown in fig. 7) is disposed on the moving base 510, a sliding rail 331 (as shown in fig. 4) is disposed on the rack body 330, the sliding block 511 is slidably engaged with the sliding rail 331, and the moving base 510 is disposed on the sliding rail 331 in a vertically sliding manner through the sliding block 511. The sliding block 511 and the sliding rail 331 cooperate to enable the sliding of the moving base 510 to be smoother and smoother, and of course, the moving base 510 can also adopt the existing screw structure cooperation mode.
In one embodiment, as shown in fig. 10, the input roller 310 includes a main roller 311 and an auxiliary roller 312, and the photovoltaic film 20 passes between the main roller 311 and the auxiliary roller 312;
this is because the support rods 501 drive the photovoltaic film 20 to move left and drive the photovoltaic film 20 to move right when stacking and accumulating, and if only one roller is not used, the pulling force of the roller on the incoming photovoltaic film 20 is affected by the movement of the photovoltaic film 20 to move left and right. After the main roller 311 and the auxiliary roller 312 are adopted, the main roller 311 and the auxiliary roller 312 clamp the photovoltaic film 20, so that the main roller 311 and the auxiliary roller 312 can keep a stable pulling force on the photovoltaic film 20 of the supplied material no matter the photovoltaic film 20 is far left or far right, and the stability of the transmission device 300 is further ensured.
In one embodiment, as shown in fig. 11, the frame body 330 is in a hollow structure, the frame body 330 is provided with a blower 332, and the blower 332 and one of the stacking components 500 are located on the same side of the frame body 330. In the lamination and accumulation process, the blower 332 can promote the air flow in the rack body 330, and the air flow direction is parallel to the lamination surface of the photovoltaic film 20, so that the flowing air can rapidly take away the heat of the photovoltaic film 20, and the laminated photovoltaic film 20 can obtain better heat dissipation effect.
In summary, according to the solar photovoltaic film production equipment 10 provided by the invention, an observer can conveniently and rapidly find the holes on the photovoltaic film 20, so that the identification difficulty is reduced, and the working efficiency is improved.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
