[0002] At present, in the process of preparing perovskite film, it is necessary to tear off the protective film on the PET film, and then carry out the subsequent slurry coating operation on the PET film, followed by drying and winding operations.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 As shown, the embodiment of the present application discloses a perovskite coating production line, comprising a feeding mechanism 1, a coating mechanism 2, a drying mechanism 3 and a receiving mechanism 4 which are sequentially arranged along the moving direction of the PET film; The feeding mechanism 1 comprises a feeding mounting plate 11, a feeding roll 12 is arranged on the feeding mounting plate 11, a buffer mechanism is arranged on one side of the feeding roll 12, a stripping mechanism is arranged on the side of the buffer mechanism away from the feeding roll 12, and also comprises a tape connection platform 13 arranged between the feeding roll 12 and the buffer mechanism; The cache mechanism includes a guide wheel assembly disposed on the feed mounting plate 11, the guide wheel assembly includes a plurality of guide wheels, and also includes a cache wheel assembly disposed between the plurality of guide wheels and capable of horizontally moving in the direction of the guide wheels; The guide wheel assembly includes a first guide wheel 14 and a second guide wheel 15 which are horizontally arranged, and a third guide wheel 16 and a fourth guide wheel 17 are arranged in sequence below the second guide wheel 15. The cache wheel assembly includes a first cache wheel 18 and a second cache wheel 19, and the first cache wheel 18 and the second cache wheel 19 are located below the first guide wheel 14. It also includes a cache wheel driving plate 110, and the first cache wheel 18 and the second cache wheel 19 are arranged on the cache wheel driving plate 110, and the second cache wheel 19 is located below the first cache wheel 18. A cache driving cylinder 111 for driving the cache wheel driving plate 110 to make horizontal movement is arranged on the feeding mounting plate.

[0034] During specific operation, the PET film is conveyed forward by the feeding mechanism 1, and the protective film on the surface of the PET film is peeled off at the peeling mechanism, and the peeled protective film is rolled up on the waste reel 118, and then the PET film passes through the tension adjustment component 22 in turn to adjust the tension of the PET film, and then the PET film is destaticized in the destaticization component and then moves to the coating die 24 for coating of the perovskite slurry, and the coated PET film is sent to the drying mechanism 3 for drying, and the dried PET film is rolled up by the receiving mechanism 4; When the coil material is conveyed close to the tail end and a new coil material needs to be connected, the tape connecting platform 13 presses the coil material, and the new coil material is manually loaded and the front end of the new coil material is glued and connected to the tail end of the old coil material. During the manual loading process, the feeding operation cannot be performed at the feed roll 12. At this time, the cache wheel assembly moves horizontally in the direction of the guide wheel to release the cached material tape so that the subsequent coating operation can continue. After the new coil material at the front end is loaded, the feed roll 12 continues to feed the material. At this time, the cache wheel assembly moves horizontally away from the guide wheel to re-cache the material tape.

[0035] In addition, during specific transmission, the material belt bypasses the first guide wheel 14, the second guide wheel 15, the first cache wheel 18, the third guide wheel 16, the second cache wheel 19 and the fourth guide wheel 17 in sequence. When in the cache state, the first cache wheel 18 and the second cache wheel 19 are located away from the third guide wheel 16 and the fourth guide wheel 17. At this time, the first cache wheel 18 and the second cache wheel 19 are farther away from the third guide wheel 16 and the fourth guide wheel 17, so they can bypass a longer material belt. When the cached material belt needs to be released, the cache drive cylinder 111 drives the cache wheel drive plate 110 to move toward the third guide wheel 16 and the fourth guide wheel 17 to slowly release the material belt.

[0036] In this embodiment, the belt connecting platform 13 includes a support plate 131, a positioning cutting gap 132 is arranged in the middle of the support plate 131, a removable waste box 133 is arranged at the bottom of the support plate 131 at the positioning cutting gap 132, and a first pressing block 134 and a second pressing block 135 are respectively arranged at both ends of the support plate 131 along the product movement direction, and also includes a first pressing drive cylinder 136 for driving the first pressing block 134 to move toward the support plate 131 and a second pressing drive cylinder 137 for driving the second pressing block 135 to move toward the support plate 131.

[0037] Specifically, when the coil is conveyed close to the tail end and a new coil needs to be connected, the first press drive cylinder 136 and the second press drive cylinder 137 drive the first press block 134 and the second press block 135 to move to press the tail material, and manually load the new coil. At the same time, the operator cuts the tail end of the old coil with a blade along the positioning cutting gap 132 to make the interface of the tail end of the old coil flush. At this time, the first press block 134 is released, the waste material is taken away, and the front end of the new coil is glued and connected to the tail end of the old coil. After the connection is completed, the second press block 135 is released to continue the feeding operation.

[0038] In this structure, the arrangement of the belt splicing platform 13 can realize compaction of the tailings, making the splicing operation convenient. Meanwhile, the arrangement of the positioning cutting slit 132 can facilitate cutting of the tailings, thereby ensuring the flatness of the tailings.

[0039] In this embodiment, a first traction wheel 112 is provided between the belt connection platform 13 and the buffer mechanism, a second traction wheel 113 is provided between the buffer mechanism and the stripping mechanism, a first abutment wheel 114 and a first abutment driving mechanism 115 for driving the first abutment wheel 114 to move toward the first traction wheel 112 are provided on one side of the first traction wheel 112, and a second abutment wheel 116 and a second abutment driving mechanism 117 for driving the second abutment wheel 116 to move toward the second traction wheel 113 are provided on one side of the second traction wheel 113; The stripping mechanism includes a waste reel 118, one end of which is provided with a waste reel driving motor 119 for driving the waste reel 118 to rotate, a feed guide shaft 120 is provided below the waste reel 118, and also includes a stripping roller 121 located at the front end of the waste reel 118 and the feed guide shaft 120, one side of the stripping roller 121 is provided with a third abutment wheel 122 and a third abutment driving mechanism 123 for driving the third abutment wheel 122 to move toward the stripping roller 121, and a static elimination rod 124 is provided between the stripping roller 121 and the receiving roller; A first detection tension roller 125 is disposed between the feed roll 12 and the buffer mechanism, and a second detection tension roller 126 is disposed between the stripping roller 121 and the waste reel 118 .

[0040] Specifically, at the beginning of the work, the material belt will be manually passed between the first traction wheel 112 and the first abutment wheel 114, and between the second traction wheel 113 and the second abutment wheel 116 in sequence, and then the first abutment wheel 114 moves toward the first traction wheel 112, and the second abutment wheel 116 moves toward the second traction wheel 113, so that the material belt is closely attached to the first traction wheel 112 and the second traction wheel 113, and then the material belt can be actively transported forward under the active drive of the first traction wheel 112 and the second traction wheel 113; When performing the specific stripping operation, during the preparation work, the material strip passes between the stripping roller 121 and the third abutment wheel 122, and the operator first performs the front stripping, sticks the end of the stripped protective film on the waste roll, and the stripped PET film is pulled to the feed guide shaft 120 and wound on the winding mechanism at the very end. When performing the stripping operation, under the active rotation of the waste reel 118, the protective film is torn off and wound on the waste reel 118, and the PET film continues to be transported forward for subsequent coating, drying, and winding operations.

[0041] In the present structure, the first abutment wheel 114 and the second abutment wheel 116 are provided to facilitate the threading of the material belt, and at the same time, the threaded material belt is closely attached to the first traction wheel 112 or the second traction wheel 113, so that the material belt can be better conveyed. At the same time, in the present structure, the first tension roller and the second tension roller are provided to detect the tension of the material belt currently being transported, so that each active shaft can be adjusted in time, thereby ensuring that the material belt is in a tensioned state during transportation, thereby ensuring the accuracy of the subsequent coating material.

[0042] In this embodiment, the coating mechanism 2 includes a coating frame 21, a tension adjustment component 22 is provided at the front end of the coating frame 21, a mounting seat is provided on the coating frame 21, a coating roller 23 is provided on the mounting seat, a coating roller driving motor for driving the coating roller 23 to rotate is provided on one side of the coating roller 23, a coating die 24 is provided above the coating roller 23, a gap for the product to pass through is provided between the coating roller 23 and the coating die 24, a die adjustment component for adjusting the horizontal position and height position of the coating die 24 is also provided on the coating frame 21, and also includes a wind knife component 25 arranged in the direction of the discharge end of the coating die 24; A destaticizing component is also provided below the coating machine frame 21 , so that the product first bypasses the destaticizing component and then passes between the coating roller 23 and the coating die head 24 .

[0043] During specific operation, the PET film is conveyed to the anti-static component after the tension is adjusted by the tension adjustment component 222, and then passes between the coating roller 233 and the coating die head 244. When moving to the bottom of the coating die head 244, the coating die head 244 performs a perovskite slurry coating operation on the surface of the PET film, and then the coated PET film moves to the bottom of the wind knife component 255. Under the rapid blowing action of the wind knife, the crystallization of the perovskite slurry is accelerated. When the coating die head 244 is unstable, the die head adjustment component performs a leveling operation on the coating die head 244.

[0044] In this structure, the tension adjustment component 222 can be set to ensure the tension of the product during transportation, and the die head adjustment component can be set to adjust the horizontal and vertical positions of the die head to ensure the stability of the die head during operation.

[0045] In this embodiment, the die head adjustment assembly includes a first mounting frame 26, the bottoms of both ends of the first mounting frame 26 are slidably connected to the coating machine frame 21, and the first driving cylinder 27 and the second driving cylinder for driving the two ends of the first mounting frame 26 to move along the X-axis direction are respectively arranged on both sides of the coating machine frame 21, and the first detection block 28 and the second detection block are symmetrically arranged on both sides of the coating machine frame 21, and the first distance detection sensor 29 and the second distance detection sensor respectively cooperating with the first detection block 28 and the second detection block are symmetrically arranged at both ends of the first mounting frame 26; It also includes a second mounting frame 210, and the first mounting frame 26 has a first lifting cylinder 211 and a second lifting cylinder 212 at both ends for driving the second mounting frame 210 to perform lifting movements. The first mounting frame 26 has a third distance detection sensor and a fourth distance detection sensor 213 vertically arranged at both ends, and the first mounting frame 26 has a third detection block and a fourth detection block 214 cooperating with the third distance detection sensor and the fourth distance detection sensor 213 arranged at both ends.

[0046] Specifically, during adjustment, the first driving cylinder 27 and the second driving cylinder can respectively drive the two ends of the first mounting frame 26 to move along the X-axis direction, and the first distance detection sensor 29 and the second distance detection sensor can detect the skewness of the first mounting frame 26. When the values ​​detected by the first distance detection sensor 29 and the second distance detection sensor are the same, it means that the first mounting frame 26 is flush along the Y-axis direction at this time. If the values ​​detected by the first distance detection sensor 29 and the second distance detection sensor are different, the first driving cylinder 27 and the second driving cylinder are respectively adjusted until the first mounting frame 26 is horizontal, which means that the coating die head 24 is flush along the Y-axis direction at this time. Similarly, the first lifting cylinder 211 and the second lifting cylinder 212 can respectively adjust the heights of the two ends of the second mounting frame 210 until the values ​​detected by the third distance detection sensor and the fourth distance detection sensor 213 are equal, which means that the heights of the two ends of the coating die head 24 are flush at this time.

[0047] The setting of the above-mentioned multiple distance sensors can realize the detection of the horizontal and vertical flatness of the coating die head 24. At the same time, through the setting of two horizontal drive cylinders and two lifting drive cylinders, the two ends of the die head can be adjusted respectively, thereby ensuring the flatness of the coating die head 24 and thus ensuring the subsequent coating quality.

[0048] In this embodiment, first limit mounting frames 215 are respectively provided at both ends of the first mounting frame 26, a first limit block 216 is provided on the first limit mounting frame 215, the first limit block 216 is slidably connected to the first limit mounting frame 215, a limit driving motor 217 for driving the first limit block 216 to move along the X-axis direction is provided on the first limit mounting frame 215, a second limit mounting frame 218 is provided on the second limit mounting frame 210, a second limit block 219 facing the first limit block 216 is provided on the second limit mounting frame 218, a first inclined surface structure is provided on the surface of the first limit block 216, and a second inclined surface structure matching the first inclined surface structure is provided on the bottom surface of the second limit block 219; The destaticization component includes a deionizing fan 220, and a plurality of first rollers 221 are arranged below the air outlet of the deionizing fan 220. A perforation 222 is arranged on the coating frame 21 below the coating roller 23. An adjusting roller assembly is arranged below the coating roller 23, and also includes a first guide roller arranged between the adjusting roller assembly and the first roller 221.

[0049] Specifically, when the coating die head 24 is controlled to descend to the working position, when the first limit block 216 abuts against the second limit block 219, the coating die head 24 cannot continue to descend. When it is necessary to adjust the descending limit height of the coating die head 24, the first limit block 216 is driven to move along the X-axis direction by the limit drive motor 217. Since the surface of the first limit block 216 is a slope structure, when the position of the first limit block 216 is adjusted, the distance from the first limit block 216 to the highest surface to the ground can be adjusted, that is, the limit height of the coating die head 24 when descending is adjusted.

[0050] In this structure, the die head height can be limited by the coordinated use of the first limit block 216 and the second limit block 219, and the limit height can be adjusted according to the actual product specifications, thereby ensuring the coating quality of products of various specifications.

[0051] At the same time, when the PET film passes through the anti-static assembly, the PET film first passes between the air outlet of the ion fan and multiple first rollers 221, then bypasses the first guide roller and adjustment roller assembly, passes through the perforation 222 and enters between the coating roller 23 and the coating head for coating operation.

[0052] Therefore, by setting up the anti-static component in this structure, it is possible to carry out anti-static treatment on the surface of the product before entering the coating operation, thereby ensuring the yield rate of the product during coating.

[0053] In this embodiment, the adjusting roller assembly includes a first adjusting roller 223, one end of the first adjusting roller 223 is connected to the coating machine frame 21 through a self-aligning bearing 224, the other end of the first adjusting roller 223 is connected to the coating machine frame 21 in a horizontal sliding manner along the X-axis, and the other end of the first adjusting roller 223 is provided with an adjusting roller driving mechanism 225 for driving the first adjusting roller 223 to slide horizontally relative to the coating machine frame 21; The tension adjustment assembly 22 includes an adjustment frame 226, on which a plurality of second guide rollers 227 are arranged, and a tension adjustment frame 228 is arranged between the plurality of second guide rollers 227, and an upper end of the tension adjustment frame 228 is fixedly connected to a rotating roller 229, and both ends of the rotating roller 229 are respectively rotatably connected to the tension adjustment frame 226, and a tension adjustment roller 231 is arranged at the lower end of the tension adjustment frame 228, and also includes a rotating roller driving mechanism 230 for driving the rotating roller 229 to rotate; A third tension detection roller 232 is disposed at the discharge end of the adjustment frame 226 .

[0054] Specifically, when being transported in the tension adjustment component 22, the PET film first bypasses the first second guide roller 227, then bypasses the tension adjustment roller 231, and then bypasses the other second guide rollers 227 and the third detection tension roller 232 in turn. When the third detection tension roller 232 detects that the tension value of the PET film is not within the set range, the rotating roller driving mechanism 230 drives the rotating roller 229 to rotate, thereby driving the tension adjustment roller 231 to swing, thereby adjusting the tension of the PET film. Then, when the PET film is about to move to the coating die head 24, when the PET film is positionally offset, the first adjusting roller 223 is driven to move horizontally by the adjusting roller driving mechanism 225, and then the position of the PET film fed into the coating roller 23 is fine-tuned by adjusting the position of the first adjusting roller 223.

[0055] In this structure, the tension adjustment component 22 can be arranged to ensure the tension of the product during transportation, and the first adjustment roller 223 can be arranged to adjust the position of the PET film, thereby ensuring the subsequent coating quality.

[0056] In this embodiment, the drying mechanism 3 includes an oven 31, and hot air components 32 are sequentially staggeredly arranged on the upper and lower sides of the oven 31, and a plurality of second rollers 33 are arranged in the box along the movement path of the PET film.

[0057] Specifically, after the perovskite slurry is coated on the PET film, the PET film moves into the oven 31. Under the guidance of multiple second rollers 33, the PET film moves forward. During the movement, both sides of the PET film are baked by the hot air component 32 respectively. After the baking is completed, the PET film moves out of the oven 31.

[0058] In this structure, by staggering the hot air components 32 in the upper and lower sides of the oven 31, the hot air inside the oven 31 can be made more uniform, thereby ensuring the stability of the perovskite slurry film formation on the surface of the PET film.

[0059] In this embodiment, the material receiving mechanism 4 includes a material receiving mounting plate 41, on which a fourth tension detection roller 42, a second adjustment roller 43, a third passing roller 44 and a material receiving roll 45 are sequentially arranged along the moving direction of the PET film, and a second adjustment roller driving mechanism for driving the second adjustment roller 43 to perform telescopic movement is arranged on one side of the second adjustment roller 43; It also includes a material receiving bottom plate, the material receiving mounting plate 41 is slidably connected to the material receiving bottom plate, and a material receiving mounting plate 41 driving mechanism for driving the material receiving mounting plate 41 to slide relative to the material receiving bottom plate along the Y-axis direction is provided at the bottom of the material receiving mounting plate 41; The receiving mounting plate 41 is provided with a deviation correction detection sensor 46 for detecting the edge position of the PET film.

[0060] Specifically, the above-mentioned correction detection sensor 46 can be a distance sensor, a photoelectric sensor, etc., and there are two correction sensors, which can be used to detect the two side edges of the PET film respectively. The driving mechanism of the material receiving installation plate 41 can be a cylinder, an electric cylinder, etc.

[0061] Specifically, after the PET film moves out of the oven 31, the PET film passes through the fourth detection tension roller 42, the second adjustment roller 43 and the third passing roller 44 in sequence, and is finally rolled up on the receiving roll 45. When the deflection correction detection sensor 46 on one side cannot detect the edge information of the product, it means that the PET film is skewed at this time. The driving mechanism of the receiving mounting plate 41 drives the receiving mounting plate 41 to slide along the Y-axis direction relative to the receiving bottom plate until the deflection correction detection sensors 46 on both sides can detect the edge data of the PET films on both sides. At this time, the deflection correction is completed. At the same time, the rotation speed of the receiving roll 45 is adjusted according to the data detected by the fourth detection tension roller 42, thereby ensuring the tension of the PET film during the winding operation.

[0062] In this structure, by setting the deviation correction detection sensor 46, the PET film can be corrected in real time during the movement, thereby ensuring that the PET film can be wound flatly on the collection reel 45 for collection.

[0063] The present invention also discloses a perovskite coating method, which adopts the above-mentioned perovskite coating production line, and the method is as follows: the PET film is conveyed forward by the feeding mechanism 1, and the protective film on the surface of the PET film is peeled off at the peeling mechanism, and the peeled protective film is rolled up on the waste reel 118, and then the PET film is sequentially passed through the tension adjustment component 22 to adjust the tension of the PET film, and then the PET film is destaticized in the destaticization component and then moved to the coating die head 24 for the coating operation of the perovskite slurry, and the coated PET film is sent to the drying mechanism 3 for drying treatment, and the dried PET film is rolled up by the receiving mechanism 4; When the roll is conveyed near the tail end and a new roll needs to be connected, the tape connecting platform 13 presses the roll tightly, and the new roll is manually loaded and the front end of the new roll is glued and connected to the tail end of the old roll. During the manual loading process, the feeding operation cannot be performed at the feed roll 12. At this time, the cache wheel assembly moves horizontally in the direction of the guide wheel to release the cached material tape so that the coating operation can continue. After the new roll at the front end is loaded, the feed roll 12 continues to feed the material. At this time, the cache wheel assembly moves horizontally away from the guide wheel to re-cache the material tape.

[0064] The method provides a buffer mechanism so that when a new coil of material is replaced at the front end, the material buffered at the buffer mechanism can continue to be conveyed forward, thereby eliminating the need to stop the machine during material replacement operations and allowing subsequent coating, drying and other operations to be performed uninterruptedly.

[0065] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
