DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] Figure 1 The figure shows an application scenario of a double-sided coating production line provided by an embodiment of the present application. Figure 1As shown, the double-sided coating production line 10 is configured to coat the first side 21 and the second side 22 of the sheet 2, wherein the first side 21 and the second side 22 of the sheet are arranged opposite to each other. For example, the first side of the sheet 2 is the front side of the sheet 2, and the second side of the sheet 2 is the back side of the sheet.

[0035] The double-sided coating production line 10 includes a front-side coating device 100, a back-side coating device 200, one or more first splicing devices 300, one or more second splicing devices 400, one or more face-changing devices 500, a boat transfer device 600, and one or more sheet insertion and removal devices 700. The front-side coating device 100 is configured to coat the first side 21 of a sheet. The back-side coating device 200 is configured to coat the second side 22 of a sheet. The first splicing device 300 is configured to carry one or more sheets 2. The second splicing device 400 is configured to carry one or more sheets 2. The face-changing device 500 is configured to carry two opposing edge regions of a sheet 2. The sheet insertion and unloading device 700 is configured to attract the central area of ​​the first side 21 of the sheet material to transfer one or more sheets 2 from the first sheet splicing device 300 to the first boat structure 3. After the first side 21 of the sheet material is coated, the sheet material 2 is transferred from the first boat structure 3 to the face-changing device 500. The sheet insertion and unloading device 700 is further configured to attract the central area of ​​the second side 22 of the sheet material to transfer one or more sheets 2 from the face-changing device 500 to the second boat structure 4. After the second side 22 of the sheet material is coated, the sheet material 2 is transferred from the second boat structure 4 to the second sheet splicing device 400. The central area of ​​the sheet material 2 is located between two opposing edge areas of the sheet material 2. The boat transfer device 600 is configured to carry the first boat structure 3 and transport the first boat structure 3 to or from the front coating device 100, and to carry the second boat structure 4 and transport the second boat structure 4 to or from the back coating device 200.

[0036] For example, Figure 1 As shown, the back coating apparatus 200 is disposed adjacent to the front coating apparatus 100 in a first horizontal direction X1, and the first splicing apparatus 300 is disposed opposite the front coating apparatus 100 in a second horizontal direction X2, with the second horizontal direction X2 being perpendicular to the first horizontal direction X1. The second splicing apparatus 400 is disposed adjacent to the first splicing apparatus 300 in the first horizontal direction X1 and opposite the back coating apparatus 200 in the second horizontal direction X2. The face-changing apparatus 500 is located between the first splicing apparatus 300 and the second splicing apparatus 400 in the first horizontal direction X1. The boat transfer apparatus 600 is disposed between the front coating apparatus 100 and the first splicing apparatus 300, and between the back coating apparatus 200 and the second splicing apparatus 400. The sheet insertion and removal apparatus 700 is disposed between the face-changing apparatus 500 and the front coating apparatus 100, and between the face-changing apparatus 500 and the back coating apparatus 200.

[0037] Figure 1 The multiple dashed lines with arrows in the figure show the flow process of the double-sided coating production line 10 for the sheet 2, the first boat structure 3, and the second boat structure 4 in the order from top to bottom and from right to left. For example, the flow process of the double-sided coating production line 10 for the sheet 2, the first boat structure 3, and the second boat structure 4 is as follows:

[0038] The first splicing device 300 carries the first side 21 of the sheet material, and the sheet insertion and removal device 700 suctions the central area of ​​the first side 21 of the sheet material to transfer the sheet material 2 from the first splicing device 300 to the first boat structure 3, so that the second side 22 of the sheet material contacts the first boat structure 3. The boat transfer device 600 transports the first boat structure 3 into the front coating device 100, which coats the first side 21 of the sheet material. After the first side 21 of the sheet material is coated, the boat transfer device 600 transports the first boat structure 3 out of the front coating device 100. The sheet insertion and removal device 700 suctions the central area of ​​the first side 21 of the sheet material and transfers the sheet material 2 from the first boat structure 3 to the surface changing device 500, which carries two opposite edge areas of the first side 21 of the sheet material. The sheet insertion and removal device 700 suctions the center area of ​​the second side 22 of the sheet material to transfer the sheet material 2 from the surface changing device 500 to the second boat structure 4, so that the first side 21 of the sheet material contacts the second boat structure 4. The boat transfer device 600 transports the second boat structure 4 to the back coating device 200, which coats the second side 22 of the sheet material. After the second side 22 of the sheet material is coated, the boat transfer device 600 transports the second boat structure 4 out of the back coating device 200. The sheet insertion and removal device 700 suctions the center area of ​​the second side 22 of the sheet material to transfer the sheet material 2 from the second boat structure 4 to the second sheet splicing device 400, which carries the first side 21 of the sheet material.

[0039] The double-sided coating production line 10 utilizes a first sheet splicing device 300, a second sheet splicing device 400, a surface changing device 500, and a sheet inserting and removing device 700 to change the surface and transfer the sheet material 2, thereby achieving double-sided coating of the sheet material 2 on a single production line. The double-sided coating production line 10 has a compact structure, a small footprint, and high transfer efficiency, thereby improving the production efficiency of the double-sided coating production line 10 and reducing the production cost of the double-sided coating production line 10.

[0040] For example, Figure 1 As shown, there are two first splicing devices 300, and the two first splicing devices 300 are adjacently arranged in the first horizontal direction X1. The two first splicing devices 300 are used to provide sheets 2 for the sheet insertion and unloading device 700, further improving the circulation efficiency of the double-sided coating production line 10, thereby further improving the production efficiency of the double-sided coating production line 10.

[0041] For example, Figure 1 As shown, there are two second splicing devices 400, and the two second splicing devices 400 are adjacently arranged in the first horizontal direction X1. The two second splicing devices 400 are used to receive the sheet 2 adsorbed by the inserting and unloading device 700, which further improves the circulation efficiency of the double-sided coating production line 10, thereby further improving the production efficiency of the double-sided coating production line 10.

[0042] For example, Figure 1 As shown, there are two sheet insertion and removal devices 700. One sheet insertion and removal device 700 is disposed between the face-changing device 500 and the front-side coating device 100. It is configured to absorb the first side 21 of the sheet carried by the first splicing device 300 and place the sheet 2 on the first boat structure 3, as well as absorb the first side 21 of the coated sheet carried by the first boat structure 3 and place the sheet 2 on the face-changing device 500. The other sheet insertion and removal device 700 is disposed between the face-changing device 500 and the back-side coating device 200. It is configured to absorb the second side 22 of the sheet carried by the face-changing device 500 and place the sheet 2 on the second boat structure 4, as well as absorb the second side 22 of the sheet carried by the second boat structure 4 and place the sheet 2 on the second splicing device 400. The simultaneous operation of the two sheet insertion and removal devices 700 further improves the flow efficiency of the double-sided coating production line 10, thereby further improving the production efficiency of the double-sided coating production line 10.

[0043] For example, Figure 1 As shown, the sheet inserting and removing device 700 is provided between the face changing device 500 and the boat flow transfer device 600. Figure 2 As shown, the sheet insertion and removal device 700 includes a drive assembly 710 and at least one suction assembly 720. The suction assembly 720 is connected to the drive assembly 710 so that the drive assembly 710 drives the suction assembly 720 to move, so that the suction assembly 720 can suction the first surface 21 or the second surface 22 of the sheet and drive the sheet 2 to move. For example, the drive assembly 710 can be a robotic arm, a linear module, etc., and the suction assembly 720 can be a suction cup or other structure with suction function.

[0044] Illustratively, both the first boat structure 3 and the second boat structure 4 can carry multiple sheets 2, so that the double-sided coating production line 10 can circulate and produce multiple sheets 2 at the same time, further improving the circulation efficiency of the double-sided coating production line 10, thereby further improving the production efficiency of the double-sided coating production line 10.

[0045] For example, Figure 3 and Figure 4As shown, the first boat structure 3 has a plurality of spaced and parallel boats 31. The suction assembly 720 suctions the first surface 21 of the sheet material and transfers it between two adjacent boats 31. The sheet material 2 is then placed on the first boat structure 3, with the second surface 22 of the sheet material contacting the boats 31 of the first boat structure 3. For example, the structure of the second boat structure 4 is the same as that of the first boat structure 3 and will not be further described here.

[0046] Exemplarily, the sheet 2 may be a silicon wafer, a solar panel, a glass substrate, or the like.

[0047] In some embodiments, as Figure 5 As shown, the first sheet splicing device 300 includes two first support members 310 arranged opposite to each other along the first horizontal direction X1, and the opposite sides of the two first support members 310 each have one or more first load-bearing teeth 3101, and the first load-bearing teeth 3101 of the two first support members 310 located on the same horizontal plane are configured to jointly carry a sheet 2.

[0048] The first sheet splicing device 300 uses the first carrying teeth 3101 to carry the sheet 2 , so that the sheet inserting and removing device 700 can absorb the sheet 2 carried by the first sheet splicing device 300 .

[0049] For example, Figure 1 、 Figures 3 to 5 As shown, the first bearing teeth 3101 of the two first support members 310 located on the same horizontal plane jointly support the two opposite edge areas of the first surface 21 of the sheet, and the sheet insertion and unloading device 700 adjacent to the front coating device 100 adsorbs the middle area of ​​the first surface 21 of the sheet, and places the sheet 2 on the first boat structure 3 so that the second surface 22 of the sheet is in contact with the first boat structure 3.

[0050] In some embodiments, as Figure 6 As shown, the second sheet splicing device 400 includes two second support members 410 arranged opposite to each other along the first horizontal direction X1, and the opposite sides of the two second support members 410 each have one or more second load-bearing teeth 4101, and the second load-bearing teeth 4101 of the two second support members 410 located on the same horizontal plane are configured to jointly carry a sheet 2.

[0051] The second sheet splicing device 400 uses the second carrying teeth 4101 to carry the sheet 2 , so that the sheet inserting and removing device 700 can place the sheet 2 on the second sheet splicing device 400 .

[0052] Exemplarily, the second bearing teeth 4101 of the two second supporting members 410 located at the same horizontal plane jointly bear two opposite edge regions of the first surface 21 of the sheet.

[0053] In some embodiments, as Figure 7As shown, the surface changing device 500 includes two third support members 510 arranged opposite to each other along the first horizontal direction X1, and the opposite side of the two third support members 510 has one or more third load-bearing teeth 5101, and the third load-bearing teeth 5101 of the two third support members 510 located on the same horizontal plane are configured to jointly carry a sheet 2.

[0054] The face-changing device 500 uses the third carrying teeth 5101 to carry the sheet 2, so that the sheet inserting and unloading device 700 can place the sheet 2 on the face-changing device 500, and the sheet inserting and unloading device 700 can absorb the sheet 2 carried by the face-changing device 500.

[0055] For example, Figure 1 and Figure 7 As shown, the third supporting teeth 5101 of the two third supporting members 510 located on the same horizontal plane jointly support the two opposite edge areas of the first side 21 of the sheet, and the sheet insertion and removal device 700 adjacent to the back coating device 200 adsorbs the middle area of ​​the second side 22 of the sheet, and places the sheet 2 on the second boat structure 4 so that the first side 21 of the sheet is in contact with the second boat structure 4.

[0056] Exemplarily, the opposite sides of the two first support members 310 each have a plurality of first load-bearing teeth 3101, and the plurality of first load-bearing teeth 3101 are arranged at intervals in the vertical direction, and every two first load-bearing teeth 3101 located in the same horizontal plane jointly carry a sheet 2, so that the first sheet splicing device 300 can carry multiple sheets 2 at the same time. In addition, the sheet insertion and unloading device 700 includes multiple adsorption components 720, which facilitates the driving component 710 to drive the multiple adsorption components 720 to simultaneously adsorb multiple sheets 2, and place the multiple sheets 2 on the first boat structure 3 at the same time, further improving the circulation efficiency of the double-sided coating production line 10, thereby further improving the production efficiency of the double-sided coating production line 10.

[0057] Exemplarily, the opposite side of the two third support members 510 has a plurality of third load-bearing teeth 5101, and the plurality of third load-bearing teeth 5101 are arranged at intervals in the vertical direction, and every two third load-bearing teeth 5101 located in the same horizontal plane jointly carry a sheet 2, so that the face-changing device 500 can simultaneously receive multiple sheets 2 adsorbed by the sheet inserting and unloading device 700, and it is also convenient for the sheet inserting and unloading device 700 to simultaneously adsorb multiple sheets 2 carried by the face-changing device 500, and place the multiple sheets 2 on the second boat structure 4 at the same time, thereby improving the efficiency of taking and placing sheets by the sheet inserting and unloading device 700, as well as the face-changing efficiency of the sheet inserting and unloading device 700 and the face-changing efficiency of the sheet 2 by the sheet inserting and unloading device 700 and the face-changing device 500.

[0058] Exemplarily, the opposite side of the two second support members 410 has a plurality of second load-bearing teeth 4101, and the plurality of second load-bearing teeth 4101 are arranged at intervals in the vertical direction. Every two second load-bearing teeth 4101 located in the same horizontal plane jointly carry a sheet 2, so that the second sheet splicing device 400 can simultaneously receive multiple sheets 2 adsorbed by the sheet insertion and removal device 700, further improving the circulation efficiency of the double-sided coating production line 10, thereby further improving the production efficiency of the double-sided coating production line 10.

[0059] In some embodiments, as Figure 1 、 Figure 8 and Figure 9 As shown, there are multiple surface changing devices 500, and the multiple surface changing devices 500 are arranged adjacent to each other in sequence along the first horizontal direction X1. The double-sided coating production line 10 also includes a first moving device 800, which is connected to the multiple surface changing devices 500 and is configured to drive the multiple surface changing devices 500 to move along the first horizontal direction X1.

[0060] By providing multiple face-changing devices 500, it is convenient for the sheet insertion and removal device 700 to place the sheet 2 on the multiple face-changing devices 500, thereby ensuring the flow rhythm of the sheet 2 and effectively avoiding the occurrence of sheet 2 flow stagnation, thereby further improving the face-changing efficiency of the sheet insertion and removal device 700 and the face-changing device 500 for the sheet 2. In addition, by combining the multiple face-changing devices 500 using the first moving device 800, and using the first moving device 800 to drive the multiple face-changing devices 500 to move independently or simultaneously, the flow rhythm of the sheet 2 can also be accelerated, thereby further improving the face-changing efficiency of the sheet 2.

[0061] In some embodiments, as Figure 8 As shown, the first moving device 800 includes a first fixing assembly 810 and a plurality of first movers 820. The first fixing assembly 810 extends along a first horizontal direction X1, and the plurality of first movers 820 are slidably connected to the first fixing assembly 810 along the first horizontal direction X1. The plurality of first movers 820 are respectively connected to the plurality of face-changing devices 500 to drive the plurality of face-changing devices 500 to independently move along the first horizontal direction X1.

[0062] Exemplarily, there are two face-changing devices 500 and two first movers 820. The two first movers 820 are respectively connected to the two face-changing devices 500 to drive the two face-changing devices 500 to move independently along the first horizontal direction X1. The two face-changing devices 500 receive the sheet 2 adsorbed by the sheet insertion and removal device 700 adjacent to the front coating device 100 at a position near the first end 8101 of the first fixing assembly, and then move along the first horizontal direction X1 to a position near the second end 8102 of the first fixing assembly. The sheet insertion and removal device 700 adjacent to the back coating device 200 adsorbs the sheet 2 carried by the two face-changing devices 500.

[0063] In some embodiments, as Figure 9 As shown, the first moving device 800 includes a second fixing assembly 830 and a second mover 840. The second fixing assembly 830 extends along the first horizontal direction X1, and the second mover 840 is slidably connected to the second fixing assembly 830 along the first horizontal direction X1. The second mover 840 is connected to the multiple face-changing devices 500 to drive the multiple face-changing devices 500 to move simultaneously along the first horizontal direction X1.

[0064] Exemplarily, there are two face-changing devices 500, and the second mover 840 is connected to the two face-changing devices 500 to drive the two face-changing devices 500 to move simultaneously along the first horizontal direction X1. The two face-changing devices 500 receive the sheet 2 adsorbed by the sheet insertion and removal device 700 adjacent to the front coating device 100 at a position near the first end 8301 of the second fixing assembly, and simultaneously move along the first horizontal direction X1 to a position near the second end 8302 of the second fixing assembly, where the sheet insertion and removal device 700 adjacent to the back coating device 200 adsorbs the sheet 2 carried by the two face-changing devices 500.

[0065] Using one mover to simultaneously drive multiple surface changing devices 500 to move can simplify the structure of the double-sided coating production line 10 and save costs, compared with using multiple movers to separately drive multiple surface changing devices 500 to move.

[0066] For example, Figure 1 and Figure 7 As shown, there is one face-changing device 500, and the first moving device 800 includes a third fixing assembly 850 and a third mover 860. The third fixing assembly 850 extends along the first horizontal direction X1, and the third mover 860 is slidably connected to the third fixing assembly 850 along the first horizontal direction X1. The third mover 860 is connected to the face-changing device 500 to drive the face-changing device 500 to move along the first horizontal direction X1.

[0067] Exemplarily, the surface changing device 500 receives the sheet 2 adsorbed by the sheet insertion and removal device 700 adjacent to the front coating device 100 at a position close to the first end 8501 of the third fixed component, and moves along the first horizontal direction X1 to a position close to the second end 8502 of the third fixed component, and the sheet insertion and removal device 700 adjacent to the back coating device 200 adsorbs the sheet 2 carried by the surface changing device 500.

[0068] Compared with using one surface changing device 500 to change the surface and circulate the sheet 2, using multiple surface changing devices 500 to cooperate with the sheet insertion and unloading device 700 to change the surface and circulate the sheet 2, the surface changing efficiency and circulation efficiency of the double-sided coating production line 10 are higher, which can further improve the production efficiency of the double-sided coating production line 10.

[0069] In some embodiments, as Figure 1 As shown, the double-sided coating production line 10 also includes one or more spare surface changing devices 900, which are arranged adjacent to the surface changing device 500 in the vertical direction. The spare surface changing device 900 is configured to support two opposite edge areas of the sheet 2.

[0070] The face changing device 500 and the standby face changing device 900 operate independently, ensuring the stability and reliability of the double-sided coating production line 10. The standby face changing device 900 has the same structure as the face changing device 500.

[0071] In some embodiments, there are multiple standby face-changing devices 900, each of which is adjacently positioned along the first horizontal direction X1. The double-sided coating production line 10 further includes a second moving device 1000, which is connected to the multiple standby face-changing devices 900 and configured to drive the multiple standby face-changing devices 900 to move along the first horizontal direction X1. The second moving device 1000 has the same structure as the first moving device 800.

[0072] By providing multiple standby face-changing devices 900 as backup, the sheet insertion and removal device 700 can easily load and place the sheet 2 on the multiple standby face-changing devices 900, thereby ensuring the flow rhythm of the sheet 2 and effectively avoiding the stagnation of the sheet 2 flow, thereby further improving the face-changing efficiency of the sheet 2. In addition, by combining the multiple standby face-changing devices 900 using the second moving device 1000 and using the second moving device 1000 to drive the multiple standby face-changing devices 900 to move independently or simultaneously, the flow rhythm of the sheet 2 can also be accelerated, thereby further improving the face-changing efficiency of the sheet 2.

[0073] For example, Figure 10 and Figure 11 As shown, there are two standby face-changing devices 900 , and the two standby face-changing devices 900 are adjacently arranged along the first horizontal direction X1 .

[0074] For example, Figure 1 As shown, there is one face-changing device 500 and one backup face-changing device 900. The second moving device 1000 is connected to the backup face-changing device 900 to drive the backup face-changing device 900 to move along the first horizontal direction X1. Compared with a single backup face-changing device 900, multiple backup face-changing devices 900 can better coordinate with the sheet insertion and removal device 700 to change the face of the sheet 2 and circulate it. This improves the face-changing efficiency and circulation efficiency of the double-sided coating production line 10, further improving the production efficiency of the double-sided coating production line 10.

[0075] In some embodiments, as Figures 7 to 11 As shown, the first moving device 800 is arranged above the face-changing device 500, and the second moving device 1000 is arranged below the standby face-changing device 900 to prevent the first moving device 800 and the second moving device 1000 from interfering with the inserting and removing device 700.

[0076] In some embodiments, as Figure 1 As shown, the front coating device 100 has a first accommodating chamber 101 and a first opening 102 connecting the first accommodating chamber 101 with the outside world, and the first boat structure 3 can enter and exit the first accommodating chamber 101 through the first opening 102. The back coating device 200 has a second accommodating chamber 201 and a second opening 202 connecting the second accommodating chamber 201 with the outside world, and the second boat structure 4 can enter and exit the second accommodating chamber 201 through the second opening 202. The second opening 202 and the first opening 102 are both oriented toward the side close to the face-changing device 500, so as to facilitate the second boat structure 4 to enter and exit the second accommodating chamber 201, and the first boat structure 3 to enter and exit the first accommodating chamber 101.

[0077] In some embodiments, as Figure 12As shown, the boat transfer device 600 includes multiple third moving devices 610, one or more fourth moving devices 620, and multiple fifth moving devices 630. The multiple third moving devices 610 are disposed between the front coating device 100 and the first splicing device 300, and between the back coating device 200 and the second splicing device 400. The multiple third moving devices 610 are respectively configured to carry the first boat structure 3 and the second boat structure 4, and independently drive the first boat structure 3 and the second boat structure 4 along the second horizontal direction X2 to transport the first boat structure 3 into or out of the front coating device 100, and to transport the second boat structure 4 into or out of the back coating device 200. One or more fourth moving devices 620 are connected to the multiple third moving devices 610. The fourth moving devices 620 are configured to independently drive the multiple third moving devices 610 along the first horizontal direction X1, thereby driving the corresponding first boat structure 3 or second boat structure 4 to move along the first horizontal direction X1. The plurality of fifth moving devices 630 are located between the plurality of third moving devices 610 and the face-changing device 500 in the second horizontal direction X2, and are configured to carry the first boat structure 3 and the second boat structure 4 and transport the first boat structure 3 and the second boat structure 4 to the third moving device 610. The sheet inserting and unloading device 700 inserts or removes the sheet 2 into or from the first boat structure 3 and the second boat structure 4 carried by the fifth moving device 630.

[0078] The boat circulation device 600 facilitates the circulation of the first boat structure 3 and the second boat structure 4 along the first horizontal direction X1 and the second horizontal direction X2.

[0079] For example, Figure 12 As shown, the boat circulation device 600 includes four third moving devices 610, four fourth moving devices 620, and four fifth moving devices 630. Two of the fifth moving devices 630 are used to transport the first boat structure 3, and the other two fifth moving devices 630 are used to transport the second boat structure 4. The four fourth moving devices 620 are respectively connected to the four third moving devices 610, and the four fourth moving devices 620 respectively drive the four third moving devices 610 to move along the first horizontal direction X1, so that the third moving devices 610 are aligned with the fifth moving devices 630, so that the fifth moving devices 630 can transport the first boat structure 3 or the second boat structure 4 to the third moving devices 610; or, so that the fifth moving devices 630 can receive the first boat structure 3 or the second boat structure 4 transported by the third moving devices 610.

[0080] For example, Figure 12As shown, one sheet inserting and unloading device 700 is disposed between two fifth movable devices 630 adjacent to the first sheet splicing device 300. Another sheet inserting and unloading device 700 is disposed between two fifth movable devices 630 adjacent to the second sheet splicing device 400, so as to minimize the footprint of the double-sided coating production line 10 in the second horizontal direction X2, thereby further reducing the footprint of the double-sided coating production line 10.

[0081] For example, Figure 12 As shown, the boat circulation device 600 also includes a plurality of sixth moving devices 640 and a plurality of seventh moving devices 650. The plurality of sixth moving devices 640 are arranged between the front coating device 100 and the plurality of third moving devices 610, and between the back coating device 200 and the plurality of third moving devices 610. The plurality of sixth moving devices 640 are respectively configured to carry the first boat structure 3 and the second boat structure 4, and independently drive the first boat structure 3 and the second boat structure 4 to move along the second horizontal direction X2, so as to transport the first boat structure 3 into or out of the front coating device 100, and transport the second boat structure 4 into or out of the back coating device 200. The plurality of seventh moving devices 650 are respectively connected to the plurality of sixth moving devices 640, and respectively drive the plurality of sixth moving devices 640 to move along the first horizontal direction X1, so that the sixth moving devices 640 are aligned with the third moving device 610, so that the third moving device 610 can transport the first boat structure 3 or the second boat structure 4 to the sixth moving device 640; or so that the third moving device 610 can receive the first boat structure 3 or the second boat structure 4 transported by the sixth moving device 640. For example, the sixth moving devices 640 and the third moving devices 610 are the same in number and structure, and the seventh moving devices 650 and the fourth moving device 620 are the same in number and structure.

[0082] For example, the specific transfer process of the sheet 2 from the first splicing device 300 to the second splicing device 400 is as follows:

[0083] The sheet inserting and unloading device 700 adjacent to the first sheet splicing device 300 adsorbs the first surface 21 of the sheet carried by the first sheet splicing device 300, and places the sheet 2 on the first boat structure 3 carried by the first fifth moving device 630 adjacent to the first sheet splicing device 300, so that the second surface 22 of the sheet contacts the first boat structure 3. The fifth moving device 630 transports the first boat structure 3 to the first third moving device 610 aligned with the fifth moving device 630 along the second horizontal direction X2. The third moving device 610 receives the first boat structure 3 and transports the first boat structure 3 to the first sixth moving device 640 aligned with the third moving device 610 along the second horizontal direction X2. The sixth moving device 640 receives the first boat structure 3 and drives the first boat structure 3 to move along the second horizontal direction X2 to transport the first boat structure 3 into the front coating device 100. The front coating device 100 coats the first surface 21 of the sheet.

[0084] The second sixth moving device 640 receives the first boat structure 3 and drives the first boat structure 3 to move along the second horizontal direction X2 to transport the first boat structure 3 out of the front coating device 100 and transport the first boat structure 3 along the second horizontal direction X2 to the second third moving device 610 aligned with the sixth moving device 640. The third moving device 610 receives the first boat structure 3 and moves along the first horizontal direction X1 until it is aligned with the second fifth moving device 630 adjacent to the first splicing device 300. The third moving device 610 then transports the first boat structure 3 to the fifth moving device 630 along the second horizontal direction X2.

[0085] The sheet insertion and removal device 700 adjacent to the first sheet splicing device 300 adsorbs the first surface 21 of the sheet in the first boat structure 3 and places the sheet 2 on the surface changing device 500. The first moving device 800 drives the surface changing device 500 to move along the first horizontal direction X1 to the sheet insertion and removal device 700 adjacent to the second sheet splicing device 400.

[0086] The sheet inserting and unloading device 700 adjacent to the second sheet splicing device 400 adsorbs the second side 22 of the sheet carried by the surface changing device 500, and places the sheet 2 on the second boat structure 4 carried by the third fifth moving device 630 adjacent to the second sheet splicing device 400, so that the first side 21 of the sheet contacts the second boat structure 4, and the fifth moving device 630 transports the second boat structure 4 to the third third moving device 610 aligned with the fifth moving device 630 along the second horizontal direction X2. The third moving device 610 receives the second boat structure 4 and transports the second boat structure 4 to the third sixth moving device 640 aligned with the third moving device 610 along the second horizontal direction X2. The sixth moving device 640 receives the second boat structure 4 and drives the second boat structure 4 to move along the second horizontal direction X2 to transport the second boat structure 4 into the back coating device 200, and the back coating device 200 coats the second side 22 of the sheet.

[0087] The fourth sixth moving device 640 receives the second boat structure 4 and drives the second boat structure 4 to move along the second horizontal direction X2 to transport the second boat structure 4 out of the back coating device 200, and transports the second boat structure 4 to the fourth third moving device 610 aligned with the sixth moving device 640 along the second horizontal direction X2. The third moving device 610 receives the second boat structure 4 and moves along the first horizontal direction X1 until the third moving device 610 is aligned with the fourth fifth moving device 630 adjacent to the second splicing device 400. The third moving device 610 transports the second boat structure 4 to the fifth moving device 630 along the second horizontal direction X2.

[0088] The sheet inserting and removing device 700 adjacent to the second sheet splicing device 400 sucks the second surface 22 of the sheet carried by the second boat structure 4 and places the sheet 2 on the second sheet splicing device 400 .

[0089] Among them, such as Figure 12 As shown, the first fifth moving device 630, the second fifth moving device 630, the third fifth moving device 630 and the fourth fifth moving device 630 are arranged in sequence from the first splicing device 300 to the second splicing device 400 along the first horizontal direction X1, and the first sixth moving device 640, the second sixth moving device 640, the third sixth moving device 640 and the fourth sixth moving device 640 are arranged in sequence from the first splicing device 300 to the second splicing device 400 along the first horizontal direction X1. Figure 12 The multiple dashed lines with arrows in the figure show the specific flow process of the sheet 2, the first boat structure 3 and the second boat structure 4 in the order from top to bottom and from right to left.

[0090] In some embodiments, the double-sided coating production line 10 further includes a loading device 1100 , which is arranged adjacent to a side of the first splicing device 300 away from the front coating device 100 , and the loading device 1100 is configured to convey the sheet 2 to the first splicing device 300 .

[0091] The uncoated sheet 2 is transported to the first sheet splicing device 300 by utilizing the loading device 1100 , thereby realizing automatic loading and further improving the production efficiency of the double-sided coating production line 10 .

[0092] In some embodiments, the double-sided coating production line 10 further includes a blanking device 1200 , which is disposed adjacent to a side of the second splicing device 400 away from the back coating device 200 , and is configured to receive the sheet 2 conveyed by the second splicing device 400 .

[0093] The unloading device 1200 receives the double-sided coated sheet 2 conveyed by the second splicing device 400, thereby realizing automatic unloading and further improving the production efficiency of the double-sided coating production line 10.

[0094] In some embodiments, as Figure 1 As shown, the double-sided coating production line 10 further includes a loading device 1100 and an unloading device 1200. The loading device 1100 is disposed adjacent to a side of the first splicing device 300 that is away from the front coating device 100, and is configured to deliver the sheet 2 to the first splicing device 300. The unloading device 1200 is disposed adjacent to a side of the second splicing device 400 that is away from the back coating device 200, and is configured to receive the sheet 2 delivered by the second splicing device 400.

[0095] The loading device 1100 is used to transport the uncoated sheet 2 to the first splicing device 300, realizing automatic loading, and the unloading device 1200 is used to receive the double-sided coated sheet 2 transported by the second splicing device 400, realizing automatic unloading, thereby realizing automatic loading and unloading of the double-sided coating production line 10, and further improving the production efficiency of the double-sided coating production line 10.

[0096] Exemplarily, the loading device 1100 may be a robotic arm, a conveyor line, etc. Exemplarily, the unloading device 1200 may be a robotic arm, a conveyor line, etc.

[0097] In some embodiments, the loading device 1100 includes one or more basket loading assemblies 1110, one or more basket loading lifting assemblies 1120, a basket transfer assembly 1130, and one or more sheet material loading conveying assemblies 1140. The basket loading assemblies 1110 are configured to convey a first basket loaded with unprocessed sheet material 2. The basket loading lifting assemblies 1120 are positioned adjacent to the basket loading assemblies 1110 in the second horizontal direction X2 and are configured to drive the first basket to rise and fall. The basket transfer assembly 1130 is positioned between the basket loading assemblies 1110 and the basket loading lifting assemblies 1120 in the second horizontal direction X2 and is configured to convey the first basket from the basket loading assemblies 1110 to the basket loading lifting assemblies 1120. The sheet material loading and conveying assembly 1140 is arranged between the flower basket loading and lifting assembly 1120 and the first sheet splicing device 300 in the second horizontal direction X2, and one end of the sheet material loading and conveying assembly 1140 is located below the flower basket loading and lifting assembly 1120, so that when the flower basket loading and lifting assembly 1120 drives the first flower basket to descend, the sheet material loading and conveying assembly 1140 receives the sheet material 2 in the first flower basket.

[0098] The unloading device 1200 includes one or more sheet material unloading and conveying assemblies 1210, one or more flower basket unloading and lifting assemblies 1220, and one or more flower basket unloading and conveying assemblies 1230. The sheet material unloading and conveying assemblies 1210 are positioned adjacent to the second splicing device 400 in the second horizontal direction X2 and are configured to receive a sheet material 2, which has been coated on both the first and second sides, from the second splicing device 400. The flower basket unloading and lifting assemblies 1220 are positioned adjacent to the sheet material unloading and conveying assemblies 1210 in the second horizontal direction X2, with one end of the sheet material unloading and conveying assemblies 1210 positioned below the flower basket unloading and lifting assemblies 1220. This allows the sheet material 2, which has been coated on both the first and second sides, to be loaded into the second flower basket while the flower basket unloading and lifting assemblies 1220 drive the second flower basket upward. The flower basket unloading and conveying assemblies 1230 are configured to convey the second flower basket. The flower basket circulation assembly 1130 is further disposed between the flower basket unloading assembly 1230 and the flower basket unloading lifting assembly 1220 in the second horizontal direction X2. The flower basket circulation assembly 1130 is further configured to transport the second flower basket from the flower basket unloading lifting assembly 1220 to the flower basket unloading assembly 1230.

[0099] By setting up multiple groups of corresponding flower basket loading components 1110, flower basket loading lifting components 1120 and sheet loading conveying components 1140, multiple first splicing devices 300 are loaded at the same time. In addition, by setting up multiple groups of corresponding sheet unloading conveying components 1210, flower basket unloading lifting components 1220 and flower basket unloading components 1230, multiple second splicing devices 400 are unloaded at the same time, the automatic loading and unloading efficiency of the double-sided coating production line 10 is further improved, thereby further improving the production efficiency of the double-sided coating production line 10.

[0100] For example, Figure 13 As shown, there are four first splicing devices 300. The loading device 1100 includes two sets of basket loading assemblies 1110, two sets of basket loading and lifting assemblies 1120, and two sets of sheet material loading and conveying assemblies 1140. The two basket loading assemblies 1110 are respectively positioned adjacent to the two sets of basket loading and lifting assemblies 1120 in the second horizontal direction X2. The two basket loading assemblies 1110 convey first baskets loaded with unprocessed sheets 2 to the two basket loading and lifting assemblies 1120 via basket transfer assemblies 1130. Two sets of sheet material loading and conveying assemblies 1140 are respectively positioned in the second horizontal direction X2 between the two basket loading and lifting assemblies 1120 and the four first splicing devices 300, with one sheet material loading and conveying assembly 1140 corresponding to two first splicing devices 300. One set of sheet material feeding and conveying assemblies 1140 receives the sheets 2 from the first flower basket carried by the corresponding flower basket feeding and lifting assemblies 1120, and conveys the sheets 2 to the corresponding two first splicing devices 300. Another set of sheet material feeding and conveying assemblies 1140 receives the sheets 2 from the first flower basket carried by the corresponding other set of flower basket feeding and lifting assemblies 1120, and conveys the sheets 2 to the corresponding other two first splicing devices 300.

[0101] For example, Figure 13As shown, there are four second splicing devices 400, and the unloading device 1200 includes two sets of sheet material unloading and conveying assemblies 1210, two sets of flower basket unloading and lifting assemblies 1220, and two sets of flower basket unloading and conveying assemblies 1230. The two sets of sheet material unloading and conveying assemblies 1210 are respectively arranged adjacent to the four second splicing devices 400 in the second horizontal direction X2, with one set of sheet material unloading and conveying assemblies 1210 corresponding to two second splicing devices 400. One set of sheet material unloading and conveying assemblies 1210 receives sheets 2 that have been coated on both the first and second sides, conveyed by the corresponding two second splicing devices 400. The two sets of flower basket unloading and lifting assemblies 1220 are respectively arranged adjacent to the two sets of sheet material unloading and conveying assemblies 1210 in the second horizontal direction X2, so that the second flower baskets carried by the two sets of flower basket unloading and lifting assemblies 1220 receive sheets 2 that have been coated on both the first and second sides, conveyed by the two sets of sheet material unloading and conveying assemblies 1210. The flower basket circulation assembly 1130 transports the second flower baskets carried by the two sets of flower basket unloading and lifting assemblies 1220 to the two sets of flower basket unloading assemblies 1230 respectively.

[0102] Illustratively, the sheet loading conveyor assembly 1140 and the sheet unloading conveyor assembly 1210 are both conveyor belt streamlines.

[0103] The other end of the sheet material feeding conveying assembly 1140 is located below the first sheet splicing device 300, and the other end of the sheet material unloading conveying assembly 1210 is located below the second sheet splicing device 400. For example, Figure 5 and Figure 13 As shown, the first splicing device 300 further includes a first driving assembly 320, which is connected to the two first supporting members 310 to drive the two first supporting members 310 to rise and fall in the vertical direction, so that the first splicing device 300 can sequentially receive the sheets 2 conveyed by the sheet feeding and conveying assembly 1140. For example, as Figure 6 and Figure 13 As shown, the second splicing device 400 also includes a second drive assembly 420, which is connected to the two second support members 410 to drive the two second support members 410 to rise and fall in the vertical direction, so that the second splicing device 400 can convey multiple sheets 2 to the sheet unloading and conveying assembly 1210 in sequence.

[0104] In some embodiments, as Figure 13As shown, the unloading device 1200 also includes an unqualified flower basket unloading assembly 1240 and one or more unqualified flower basket lifting assemblies 1250.

This allows the sheet material unloading and conveying assembly 1210 to convey unqualified sheets 2 to the third flower basket while the unqualified flower basket lifting assembly 1250 drives the third flower basket upward. The flower basket transfer assembly 1130 is further disposed between the unqualified flower basket unloading assembly 1240 and the unqualified flower basket lifting assembly 1250 in the second horizontal direction X2. The flower basket transfer assembly 1130 is further configured to transport the third flower basket from the unqualified flower basket lifting assembly 1250 to the unqualified flower basket unloading assembly 1240.

[0105] The sheet material unloading and conveying assembly 1210 includes a conveyor belt assembly 1211, a sheet material detection assembly 1212, and a transverse shift assembly 1213. The conveyor belt assembly 1211 is positioned adjacent to the second sheet splicing device 400 in the second horizontal direction X2 and is configured to receive sheets 2 conveyed by the second sheet splicing device 400, both coated on the first side and coated on the second side. The sheet material detection assembly 1212 is positioned adjacent to the conveyor belt assembly 1211 and is configured to detect whether the sheets 2 conveyed by the conveyor belt assembly 1211 are qualified. The transverse shift assembly 1213 is positioned adjacent to the conveyor belt assembly 1211 in the second horizontal direction X2 and is configured to receive qualified sheets 2 and unqualified sheets 2, conveying qualified sheets 2 to the second basket and unqualified sheets 2 to the third basket.

[0106] During the unloading process, the sheet detection component 1212 is used to detect whether the sheet 2 conveyed by the conveyor belt component 1211 is qualified. The transverse movement component 1213 receives the unqualified sheet 2 and conveys the unqualified sheet 2 to the third flower basket carried by the flower basket lifting component 1250. The flower basket circulation component 1130 conveys the third flower basket from the unqualified flower basket lifting component 1250 to the unqualified flower basket unloading component 1240. The unqualified flower basket unloading component 1240 conveys the third flower basket to uniformly place the unqualified sheets 2.

[0107] Exemplarily, the sheet material detection component 1212 may detect the sheet material 2 by photographic detection or laser detection.

[0108] Illustratively, the sheet material loading and conveying assembly 1140 includes a conveyor belt assembly 1211, a sheet material detection assembly 1212, a transfer assembly 1141, and a magazine 1142. The conveyor belt assembly 1211 is disposed between the basket material loading and lifting assembly 1120 and the first sheet splicing device 300 in the second horizontal direction X2, and is configured to receive the sheets 2 from the first basket carried by the basket material loading and lifting assembly 1120. The sheet material detection assembly 1212 is disposed adjacent to the conveyor belt assembly 1211, the transfer assembly 1141 is disposed adjacent to the sheet material detection assembly 1212 in the second horizontal direction X2, and the magazine 1142 is disposed adjacent to the transfer assembly 1141, so that the transfer assembly 1141 can receive unqualified sheets 2 and place them in the magazine 1142, thereby eliminating unqualified sheets 2 during the loading process.

[0109] For example, Figure 13 As shown, there are four groups of sheet detection components 1212, among which two groups of sheet detection components 1212 are respectively arranged adjacent to the conveyor belt components 1211 of the two groups of sheet unloading and conveying components 1210, and the other two groups of sheet detection components 1212 are respectively arranged adjacent to the conveyor belt components 1211 of the two groups of sheet loading and conveying components 1140.
