Description

Technical Field

[0001] This application relates to the technical field of photovoltaic module manufacturing equipment, and particularly to a backplane film pasting device. Background Art

[0002] In order to increase the illumination area of sunlight on photovoltaic modules and improve the photoelectric conversion amount, many manufacturers have begun to set reflective film strips on the backplane of photovoltaic modules. The reflective film strips can effectively reflect the sunlight passing through the gaps between the cells and between the cell strings onto the cells, thereby making full use of the sunlight irradiated on the photovoltaic modules and improving the photoelectric conversion rate. Figure 1 Figure 10 is a schematic diagram of an existing backplane 8 provided with a reflective film strip 7.

[0003] Currently, when fixing the reflective film strips on the backplane of photovoltaic modules, it is often necessary to first place two groups of mutually perpendicular reflective film strips at the set positions on the backplane, and then heat the reflective film strips on the backplane through a heating mechanism and bond them to the backplane. The heating mechanism usually uses an infrared lamp box to irradiate the entire width of the backplane, so that the reflective film strips laid on the backplane are heated as a whole to release adhesiveness and then bonded to the backplane. However, the high temperature of the infrared lamp box is likely to cause deformation of the backplane. Utility Model Content

[0004] This application aims to at least solve one of the technical problems existing in the prior art. For this purpose, this application provides a backplane film pasting device, and the technical solution is as follows:

[0005] This application provides a backplane film pasting device, which includes a heating module and a supporting mechanism, where:

[0006] The supporting mechanism is used to carry a backplane with film strips laid on its surface. The film strips include multiple first film strips and multiple second film strips. The first film strips extend along a first horizontal direction and are arranged side by side at intervals along a second horizontal direction. The second film strips extend along the second horizontal direction and are arranged side by side at intervals along the first horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction, and the first film strips and the second film strips intersect perpendicularly;

[0007] The heating module includes a lifting drive assembly, a mounting rack, and multiple heating mechanisms mounted on the mounting rack;

[0008] The lifting drive assembly is drivingly connected to the mounting rack and is used to drive the mounting rack to lift, so as to drive each heating mechanism to approach or move away from the film strips;

[0009] The heating mechanism is used to heat the intersection positions of the first film strips and the second film strips, so that the first film strips and the second film strips at the intersection positions release adhesiveness simultaneously and bond to the backplane.

[0010] The backplane film pasting device of the present application realizes the support of the backplane with the first film strip and the second film strip through the supporting mechanism. By setting the heating module to include a mounting rack and a plurality of heating mechanisms, and making the heating mechanism only heat the intersection position of the first film strip and the second film strip, the entire surface of the backplane is avoided from being heated. It can not only ensure that the first film strip and the second film strip are smoothly bonded to the backplane, but also effectively reduce the deformation of the backplane.

[0011] Optionally, the heating module is fixedly arranged above the supporting mechanism or can be moved to above the supporting mechanism. Each heating mechanism corresponds one by one to the intersection position to be heated. When the mounting rack descends, each heating mechanism heats the corresponding intersection position simultaneously.

[0012] Based on the above heating module, each heating mechanism is horizontally moved to above the intersection position to be heated of the film strip on the backplane, and then the heating mechanism on the mounting rack is driven by the lifting drive assembly to move to the corresponding intersection position, so as to realize the simultaneous heating and bonding of all reflective film strips. When the heating module does not need to work, the heating module can also horizontally move the heating mechanism to the side of the backplane to avoid interfering with other operations such as the handling of the backplane and the handling of the film strip; the heating module can also only drive the heating mechanism to move up and down through the lifting drive assembly, as long as the heating mechanism can be raised to a position that does not interfere with other operations such as the handling of the backplane and the handling of the film strip.

[0013] Optionally, both ends of each first film strip intersect with the second film strip, and both ends of each second film strip intersect with the first film strip;

[0014] The heating mechanism of the heating module is at least used to heat the intersection positions at both ends of each first film strip and the intersection positions at both ends of each second film strip.

[0015] Based on the above heating module, by heating at least the intersection positions at both ends of each first film strip and the intersection positions at both ends of each second film strip, at least it is ensured that both end positions of each film strip can be bonded to the backplane, ensuring the connection reliability between the film strip and the backplane.

[0016] Optionally, the heating mechanism is also used to heat at least one intersection position in the middle of each first film strip and at least one intersection position in the middle of each second film strip.

[0017] On the basis of heating the intersection positions at both ends of each film strip, further heating at least one intersection position in the middle of each film strip further improves the connection reliability between each film strip and the backplane.

[0018] Optionally, the intersection positions heated by the heating mechanism on two adjacent first film strips are staggered from each other along the first horizontal direction; and / or, the intersection positions heated by the heating mechanism on two adjacent second film strips are staggered from each other along the second horizontal direction.

[0019] Based on the arrangement of the above-mentioned heated intersection positions, while ensuring the bonding effect on each first film strip and second film strip, the number of heating mechanisms can be reduced, and the staggered arrangement can also provide sufficient installation space for the heating mechanisms.

[0020] Optionally, among the heating mechanisms corresponding to the same first film strip, the distance between the heating heads of two adjacent heating mechanisms is less than 400 mm; and / or, among the heating mechanisms corresponding to the same second film strip, the distance between the heating heads of two adjacent heating mechanisms is less than 400 mm.

[0021] By setting the distance between the heating heads of two adjacent heating mechanisms to be less than 400 mm, it is possible to prevent the film strip between two adjacent bonding points from sagging when the backplane is flipped and combined with the glass.

[0022] Optionally, the heating mechanism includes a heating block, a heating rod, a temperature sensor, and a heating head. The heating block is installed on the mounting frame, the heating head is installed on the heating block, the heating rod is installed inside the heating block and is used to raise the temperature of the heating block, the heating block is used to raise the temperature of the heating head, and the heating head is used to spot-iron the intersection position of the film strip; the temperature sensor is spaced from the heating rod on the heating block, and the temperature sensor is used to monitor the temperature of the heating block.

[0023] Based on the above heating mechanism, the heating block can be made of a high thermal conductivity material, which can quickly transfer the high temperature generated by the heating rod to the heating head to improve the heating efficiency of the heating head. Such a setting can decompose the internal part of the heating mechanism into multiple structures to form a modular structure, so that the heating block, the heating head, and the heating rod are made of different materials respectively and assembled into a complete heating mechanism, thereby reducing the overall cost.

[0024] Optionally, the heating mechanism further includes a pressing structure, which includes an elastic connecting member and a pressing block. The elastic connecting member can elastically deform in the vertical direction. The pressing block is connected to the mounting frame through the elastic connecting member. The bottom of the pressing block forms a pressing surface for pressing the film strip. When the elastic connecting member is in the natural state, the pressing surface is lower than the heating head, and a through hole for the heating head to pass through longitudinally is provided on the pressing block.

[0025] Based on the above pressing structure, the pressing block can ensure that when the heating head contacts the film strip and when the heating head just moves away from the film strip, the pressing block can always stably press the film strip onto the backplane through the elastic deformation of the elastic connecting member, avoiding the film strip from detaching from the backplane due to being adhered by the heating head.

[0026] Optionally, the number of the first film strips is more than the number of the second film strips;

[0027] The backplane film laminating device further includes a track extending along the first horizontal direction. The mounting frame includes a plurality of cross beams, which extend along the second horizontal direction. The cross beams are arranged side by side along the first horizontal direction, and the number of cross beams is equal to the number of second film strips in the first horizontal direction. A heating mechanism is installed on each cross beam.

[0028] The lifting drive assembly includes lifting parts that are drivingly connected to the cross beams one by one, and each lifting part is slidably arranged on the track.

[0029] By setting the mounting frame to include a plurality of cross beams, and the number of cross beams being the same as the number of second film strips, and the cross beams being slidable along the track, when the spacing between the second film strips on different types of backplanes is different, by adjusting the position of the cross beams on the track, the cross beams can be moved above the corresponding second film strips to heat the intersection position of the second film strip and the first film strip, improving the compatibility of the backplane film laminating device.

[0030] Optionally, the backplane film laminating device further includes a spacing component, which includes a driving part and movers connected to each lifting part one by one. Each mover is arranged on the track, and the driving part is used to drive each mover to slide on the track so that a set distance is provided between any two adjacent cross beams.

[0031] By setting the spacing component, automatic adjustment of the spacing between the cross beams can be achieved, improving the film laminating efficiency.

[0032] Optionally, the backplane film laminating device further includes a rectifying mechanism, which is arranged around the periphery of the supporting mechanism and is used to clamp at least two opposite sides of the backplane located on the supporting mechanism to rectify the backplane.

[0033] By setting the rectifying mechanism, automatic position adjustment of the backplane carried on the supporting mechanism can be achieved, ensuring that the heating mechanism can accurately heat the intersection position of the film strips. Description of the Drawings

[0045] Some embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present application and are not intended to limit the protection scope of the present application.

[0046] Currently, when fixing the reflective film strip on the back plate of the photovoltaic module, it is often necessary to first place two sets of mutually perpendicular reflective film strips at the set positions on the back plate, and then use the heating mechanism to heat the reflective film strips on the back plate and bond them to the back plate. Taking Figure 1 as an example, Figure 1The figure shows two sets of reflective film strips 7 arranged perpendicularly to each other on the backsheet 8, ready for bonding or having been bonded. The two sets of reflective film strips 7 include 25 reflective film strips 7 extending along the width direction of the backsheet and arranged at intervals along the length direction of the backsheet 8, and 7×2 reflective film strips 7 (7 strips on each of the left and right halves of the backsheet) extending along the length direction of the backsheet 8 and arranged at intervals along the width direction of the backsheet 8. It should be noted that the number of the two sets of reflective film strips 7 on the backsheet 8 is determined by the format of the photovoltaic module. Figure 1 The heating mechanism is usually an infrared light box, which illuminates the entire width of the back plate 8, so that the reflective film strips 7 laid on the back plate 8 are heated to release the adhesive and then adhere to the back plate. However, the high temperature of the infrared light box can easily cause the back plate to deform.

[0047] Based on this, the present application provides a back panel film laminating device, which supports the back panel with a first film strip and a second film strip through a supporting mechanism. By setting the heating module to include a mounting frame and multiple heating mechanisms, and making the heating mechanism only heat the intersection position of the first film strip and the second film strip, the entire width of the back panel is avoided from being heated, which can not only ensure that the first film strip and the second film strip are smoothly bonded to the back panel, but also effectively reduce the deformation of the back panel.

[0048] The present application will be described in detail below through specific embodiments.

[0049] Reference Figures 1 to 8 As shown, this embodiment provides a backplane film-laminating device, which includes a heating module 10 and a supporting mechanism 5, wherein: the supporting mechanism 5 is used to support a backplane 8 with film strips laid on the surface, the film strips including multiple first film strips and multiple second film strips, the first film strips extending along a first horizontal direction and arranged side by side and spaced along a second horizontal direction, the second film strips extending along the second horizontal direction and arranged side by side and spaced along the first horizontal direction, the first horizontal direction is perpendicular to the second horizontal direction, wherein the first horizontal direction can be the width direction of the backplane 8, the second horizontal direction can be the length direction of the backplane 8, and the first film strips and the second film strips intersect perpendicularly; the heating module 10 includes a lifting drive assembly 11, a mounting frame 12 and multiple heating mechanisms 13 installed on the mounting frame 12; the lifting drive assembly 11 is driven and connected to the mounting frame 12, and is used to drive the mounting frame 12 to lift and lower, so as to drive each heating mechanism 13 to approach or move away from the film strip; the heating mechanism 13 is used to heat the intersection position of the first film strip and the second film strip, so that the first film strip and the second film strip at the intersection position release their viscosity at the same time and adhere to the backplane 8.

[0050] The backplane film pasting device provided in this embodiment realizes the support for the backplane 8 with the first film strip and the second film strip through the supporting mechanism 5. By setting the heating module 10 to include the mounting frame 12 and a plurality of heating mechanisms 13, and making the heating mechanism 13 only heat the intersection position of the first film strip and the second film strip, the entire width of the backplane 8 is prevented from being heated. This can not only ensure that the first film strip and the second film strip are smoothly adhered to the backplane 8, but also effectively reduce the deformation of the backplane 8.

[0051] Continue to refer to Figure 2 As shown, in some embodiments, the heating module 10 is fixedly arranged above the supporting mechanism 5 or can be moved above the supporting mechanism 5. Each heating mechanism 13 corresponds to the intersection position to be heated one by one. When the mounting frame 12 descends, each heating mechanism 13 heats the corresponding intersection position simultaneously.

[0052] That is to say, the heating module 10 can horizontally move each heating mechanism 13 above the intersection position to be heated of the film strip on the backplane 8, and then drive the heating mechanism 13 on the mounting frame 12 to move to the corresponding intersection position through the lifting drive assembly 11, so as to realize the simultaneous heating and bonding of all the reflective film strips 7. When the heating module 10 does not need to work, the heating module 10 can also horizontally move the heating mechanism 13 to the side of the backplane 8 to avoid interfering with other operations such as the handling of the backplane 8 and the handling of the film strip; the heating module 10 can also only drive the heating mechanism 13 to move up and down through the lifting drive assembly 11, as long as it can make the heating mechanism 13 rise to a position that does not interfere with other operations such as the handling of the backplane 8 and the handling of the film strip.

[0053] Continue to refer to Figure 1 and Figure 2 As shown, in some embodiments, both ends of each first film strip intersect with the second film strip, and both ends of each second film strip intersect with the first film strip; the heating mechanism 13 of the heating module 10 is at least used to heat the intersection positions at both ends of each first film strip and the intersection positions at both ends of each second film strip.

[0054] By heating at least the intersection positions at both ends of each first film strip and the intersection positions at both ends of each second film strip, at least it is ensured that both end positions of each reflective film strip 7 can be adhered to the backplane 8, ensuring the connection reliability between the reflective film strip 7 and the backplane 8.

[0055] Take Figure 1Taking the backplane 8 and the reflective film strips 7 shown as an example, the 25 reflective film strips 7 extending along the width direction of the backplane are the first film strips, and the 7×2 reflective film strips 7 extending along the length direction of the backplane are the second film strips. Among them, both ends of each first film strip intersect with the second film strips, and both ends of each second film strip intersect with the first film strips. The above intersection positions will be heated by the heating mechanism 13 and adhered to the backplane 8. That is to say, the 6 film strips at the edge of the backplane 8 and one first film strip in the middle of the backplane 8 surround and form two rectangular areas. All the intersection positions of the first film strips and the second film strips at the edge of the rectangular area are heated by the heating mechanism 13 and adhered to the backplane 8, ensuring the connection stability between each reflective film strip 7 and the backplane 8.

[0056] In some embodiments, the heating mechanism 13 is further configured to heat at least one intersection position in the middle of each first film strip, and at least one intersection position in the middle of each second film strip.

[0057] It should be noted that the middle of the first film strip refers to any position between the two ends of the first film strip; the middle of the second film strip refers to any position between the two ends of the second film strip; such a design can further increase the connection point positions between the first film strip and the second film strip and the backplane 8, thereby improving the bonding reliability between the first film strip and the second film strip and the backplane 8.

[0058] In a further embodiment, the intersection positions heated by the heating mechanism 13 on two adjacent first film strips are staggered from each other along the first horizontal direction; and / or, the intersection positions heated by the heating mechanism 13 on two adjacent second film strips are staggered from each other along the second horizontal direction; arranging the intersection positions heated by the heating mechanism 13 in this way can reduce the number of heating mechanisms 13 provided while ensuring the bonding effect on each first film strip and second film strip, and the staggered arrangement can also provide sufficient installation space for the heating mechanism 13.

[0059] Continue to refer to Figures 1 to 4 As shown, in some embodiments, among the heating mechanisms 13 corresponding to the same first film strip, the distance between the heating heads 132 of two adjacent heating mechanisms 13 is less than 400 mm, such as 100 mm, 150 mm, 200 mm, 250 mm, 300 mm, 350 mm, 390 mm; and / or, among the heating mechanisms 13 corresponding to the same second film strip, the distance between the heating heads 132 of two adjacent heating mechanisms 13 is less than 400 mm, such as 100 mm, 150 mm, 200 mm, 250 mm, 300 mm, 350 mm, 390 mm.

[0060] After the bonding of the reflective film strip 7 and the back plate 8 is completed, the back plate 8 needs to be flipped by 180° and then combined with the battery string assembly for glass combination operation. By setting the distance between the heating heads 132 of two adjacent heating mechanisms 13 to be less than 400 mm, it is possible to avoid the film strip between two adjacent bonding points on the same film strip from sagging due to being too long when the back plate 8 is flipped for glass combination, which affects the glass combination quality of the assembly.

[0061] Continue to refer to Figures 5 to 8 As shown, in some embodiments, the heating mechanism 13 includes a heating block 131, a heating rod 133, a temperature sensor 134, and a heating head 132. The heating block 131 is installed on the mounting frame 12, the heating head 132 is installed on the heating block 131, the heating rod 133 is installed inside the heating block 131 and is used to heat up the heating block 131. The heating block 131 is used to heat up the heating head 132, and the heating head 132 is used to spot-iron the intersection position of the reflective film strip 7. Optionally, the heating block 131 can be made of a high thermal conductivity material, which can quickly transfer the high temperature generated by the heating rod 133 to the heating head 132 to improve the heating efficiency of the heating head 132. Such a setting can decompose the internal part of the heating mechanism 13 into multiple structures to form a modular structure, so that the heating block 131, the heating head 132, and the heating rod 133 are made of different materials and assembled to form a complete heating mechanism 13, thereby reducing the overall cost.

[0062] Continue to refer to Figure 8 As shown, the temperature sensor 134 and the heating rod 133 are arranged at intervals on the heating block 131. The temperature sensor 134 is used to monitor the temperature of the heating block 131. The temperature sensor 134 and the heating rod 133 are arranged at intervals on the heating block 131, and the temperature sensor 134 is used to monitor the temperature of the heating block 131. The temperature sensor 134 can specifically be a thermocouple, which can be electrically connected to the PLC and can monitor the temperature of the heating block 131 in real time. When it is detected that the temperature of the heating block 131 is too high, the heating rod 133 can be controlled to cut off the power or the power-on parameters of the heating rod 133 can be adjusted to lower the temperature of the heating block 131. When it is detected that the temperature of the heating block 131 is too low, the heating rod 133 can be controlled to be powered on or the power-on parameters of the heating rod 133 can be adjusted to raise the temperature of the heating block 131.

[0063] In some embodiments, the heating mechanism 13 further includes a heat insulation block 136 arranged between the heating block 131 and the mounting frame 12. The heat insulation block 136 is specifically made of a heat insulation material, which can effectively reduce the heat transfer efficiency between the heating block 131 and the mounting frame 12 and avoid the heat generated by the heating block 131 from having an adverse effect on the mounting frame 12. For example, the high temperature generated by the heating block 131 may cause the mounting frame 12 to deform, etc. Through the setting of the heat insulation block 136, the mounting frame 12 can also be made of a heat-resistant material, thereby reducing the overall cost.

[0064] In some embodiments, the heating mechanism 13 includes a pressing structure 135. The pressing structure 135 includes an elastic connecting member 1351 and a pressing block 1352. The elastic connecting member 1351 can elastically deform in the vertical direction. The pressing block 1352 is connected to the mounting bracket 12 through the elastic connecting member 1351. A pressing surface for pressing the film strip is formed at the bottom of the pressing block 1352. When the elastic connecting member 1351 is in the natural state, the pressing surface is lower than the heating head 132. A through hole 1353 is provided on the pressing block 1352 for the heating head 132 to longitudinally pass through.

[0065] The optional working process of the pressing structure 135 in the above embodiments is as follows:

[0066] The mounting bracket 12 drives the pressing structure 135 and the heating mechanism 13 to descend. Since the pressing surface is lower than the heating head 132 when the elastic connecting member 1351 is in the natural state, the pressing surface first contacts the film strip. As the mounting bracket 12 continues to descend, while the pressing block 1352 presses the film strip, the elastic connecting member 1351 is compressed. After the elastic connecting member 1351 is compressed by a certain length, the heating head 132 on the heating mechanism 13 starts to contact the film strip and starts to heat the film strip. During the process of the heating head 132 heating the film strip, the pressing block 1352 always provides a pressing force on the film strip to improve the stability of the film strip during heating.

[0067] After the film strip is heated, the mounting bracket 12 drives the pressing structure 135 and the heating mechanism 13 to ascend. Among them, the heating head 132 of the heating mechanism 13 first leaves the film strip, and the pressing block 1352 can maintain the pressing on the film strip under the action of the elastic connecting member 1351 until the elastic connecting member 1351 returns to the natural state, and the pressing block 1352 then disengages from the film strip. Thus, even if the film strip adheres to the heating head 132, the film strip will not be lifted by the heating head 132 when the heating head 132 leaves the film strip, ensuring the connection reliability between the film strip and the back plate.

[0068] Optionally, the elastic connecting member 1351 includes a guide post and a spring sleeved on the guide post. The pressing block 1352 is movably mounted on the mounting bracket 12 through the guide post. The upper end of the spring abuts against the mounting bracket 12, and the lower end abuts against the pressing block 1352.

[0069] Continue to refer to Figure 5 and Figure 8 As shown, optionally, one pressing block 1352 is provided, and a through hole 1353 for the heating head 132 to pass through is provided on the pressing block 1352; or, at least two pressing blocks 1352 are provided, and the pressing blocks 1352 are arranged at intervals along the circumferential direction of the heating head 132. An avoidance space for avoiding the heating head 132 is formed between the pressing blocks 1352, and the heating head 132 is used to pass through the avoidance space to heat the reflective film strip 7.

[0070] Continue to refer to Figure 2As shown, in some embodiments, the number of the first film strips is greater than that of the second film strips; the backplane film pasting device further includes a track 2 extending along a first horizontal direction, the mounting frame 12 includes a plurality of cross beams 121, the cross beams 121 extend along a second horizontal direction, the cross beams 121 are arranged side by side along the first horizontal direction, the number of the cross beams 121 is equal to the number of the second film strips in the first horizontal direction, and a heating mechanism 13 is mounted on each cross beam 121; the lifting drive assembly 11 includes lifting parts drivingly connected to the cross beams 121 in one-to-one correspondence, and the lifting parts are respectively slidably arranged on the track 2.

[0071] Since the number of the second film strips is small, setting the number of the cross beams 121 to match the number of the second film strips can reduce the number of the cross beams 121, thereby reducing the cost and the control difficulty of the cross beams 121, and it is easier to move all the heating mechanisms 13 quickly and accurately into place to heat all the set intersection positions.

[0072] By setting the mounting frame 12 to include a plurality of cross beams 121 and the number of the cross beams 121 to be consistent with the number of the second film strips, and the cross beams 121 can slide along the track 2, so when the distances between the second film strips on the backplanes 8 of different versions are different, by adjusting the positions of the cross beams 121 on the track 2, the cross beams 121 can be moved above the corresponding second film strips to heat the intersection positions of the second film strips and the first film strips, improving the compatibility of the backplane film pasting device.

[0073] Continue to refer to Figure 3 As shown, in some embodiments, the backplane film pasting device further includes a spacing component 30, the spacing component 30 includes a driving part 31 and movers 32 connected to the lifting parts in one-to-one correspondence, the movers 32 are arranged on the track 2, and the driving part 31 is used to drive the movers 32 to slide on the track 2 so that a set distance is provided between any two adjacent cross beams 121; thus, the automatic adjustment of the distances between the cross beams 121 can be realized through the spacing component 30, improving the film pasting efficiency.

[0074] Continue to refer to Figure 2 and Figure 4 As shown, optionally, the backplane film pasting device further includes a rectifying mechanism 40, the rectifying mechanism 40 is disposed around the periphery of the supporting mechanism 5 and is used to clamp at least two opposite sides of the backplane 8 located on the supporting mechanism 5 to rectify the backplane 8.

[0075] Optionally, the alignment mechanism 40 can clamp the two side edges of the backplane 8 in the first horizontal direction to align the backplane 8 in the first horizontal direction. The alignment mechanism 40 can also clamp the two side edges of the backplane 8 in the second horizontal direction to align the backplane 8 in the second horizontal direction. The alignment mechanism 40 can also simultaneously clamp the four side edges of the backplane 8 to align the backplane 8 in the first and second horizontal directions.

[0076] In a further embodiment, the alignment mechanism 40 includes a first alignment component 41 and a second alignment component 42. The first alignment component 41 includes first alignment members 411 symmetrically arranged on both sides of the support mechanism 5 along the first horizontal direction and a first alignment driving member 412 for driving the first alignment members 411 on both sides to approach or separate from each other. The second alignment component 42 includes second alignment members 421 symmetrically arranged on both sides of the support mechanism 5 along the second horizontal direction and a second alignment driving member 422 for driving the second alignment members 421 on both sides to approach or separate from each other.

The conveying mechanism 6 includes multiple conveyor belts. The conveying mechanism 6 is used to convey the backplane 8 in the first horizontal direction. After the backplane 8 is conveyed above the support table, the support table lifts the backplane 8 upward to separate it from the conveying mechanism 6, and then the alignment mechanism 40 implements the alignment of the backplane 8.

[0078] Optionally, the second alignment members 421 can be arranged on both sides of the conveying mechanism 6 in the second horizontal direction, that is to say, the second alignment members 421 can be arranged at the end positions of the support mechanism 5 in the second horizontal direction. Such an arrangement can prevent the second alignment members 421 from interfering with the backplane 8 when the conveying mechanism 6 conveys the backplane 8 in the first horizontal direction. The first alignment members 411 can be specifically arranged between every two conveyor belts or on both sides of the conveyor belts in the second horizontal direction. Further, the first alignment members 411 and the second alignment members 421 can be evenly arranged in multiple numbers in the second horizontal direction and the first horizontal direction respectively, so as to evenly apply a thrust to the side edges of the backplane 8 and protect the backplane 8.

The support mechanism 5 is provided with a first avoidance channel for avoiding the first alignment member 411 in the vertical direction and the first horizontal direction, and / or the support mechanism 5 is provided with a second avoidance channel for avoiding the second alignment member 421 in the vertical direction and the second horizontal direction. The alignment lifting assembly is used to drive the first alignment assembly 41 and / or the second alignment assembly 42 to lift. Through the setting of the alignment lifting assembly, the first alignment assembly 41 and / or the second alignment assembly 42 can be controlled to lift. During the conveying process of the backplane 8, the first alignment assembly 41 and / or the second alignment assembly 42 can be lowered below the top surface of the conveyor belt. After the backplane 8 is located on the support table, the alignment lifting assembly can be used to lift the first alignment assembly 41 and / or the second alignment assembly 42 to a height higher than the backplane 8, and start to align the backplane 8. Moreover, during the film pasting process of the backplane 8, the first alignment assembly 41 and / or the second alignment assembly 42 can also be maintained at a height higher than the backplane 8, so that the backplane 8 can always be kept in the accurate working position.
