Description

Technical Field

[0001] The present application relates to the field of photovoltaic module production, and specifically to a backplane coating device. Background Art

[0002] Photovoltaic modules are generally formed by laminating a base plate, a battery string group, and a back plate. Before lamination, the battery string group is first laid on the base plate, and then the back plate is stacked on the battery string group. In order to prevent the battery string group from shifting during lamination, it is necessary to bond the battery string group to the base plate in advance with adhesive material. Since the back plate is made of transparent glass, in order to improve the aesthetics of the photovoltaic module, criss-cross film strips can be laid on the lower surface of the back plate to cover the adhesive material.

[0003] At present, the film strips are usually manually applied to the back panel in advance, and then the back panel is stacked on the battery string group. The manual film coating method is inefficient and affects the production efficiency of photovoltaic modules. Utility Model Content

[0088] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0089] In order to solve the problem of low efficiency of manual lamination, the present application provides a photovoltaic module backplane laminating device, which can implement automatic lamination of the backplane, thereby improving the lamination efficiency.

[0090] like Figure 1 to Figure 2 As shown, the backplane laminating device in the embodiment of the present application includes a distance bearing mechanism 1, a heating mechanism 2, a first feeding mechanism 3, a film strip transfer mechanism 4, a second feeding mechanism 5, a distance feeding mechanism 6 and a backplane transfer mechanism 7, wherein:

[0091] The heating mechanism 2 is arranged below the spacing support mechanism 1 .

[0092] The first feeding mechanism 3 is configured to supply a plurality of first film strips extending along a first horizontal direction (eg, the X-axis direction in the figure).

[0093] The film strip transfer mechanism 4 is configured to pick up a plurality of first film strips from the first feeding mechanism 3 and place the picked up plurality of first film strips onto the spacing support mechanism 1 .

[0094] The spacing bearing mechanism 1 is configured to adjust the spacing between a plurality of first film strips in a second horizontal direction (eg, the Y-axis direction in the figure) to a first spacing, and the second horizontal direction is perpendicular to the first horizontal direction.

[0095] The second feeding mechanism 5 is configured to supply a plurality of second film strips extending along a second horizontal direction.

[0096] The spacing loading mechanism 6 is configured to pick up a number of second film strips from the second feeding mechanism 5, and adjust the spacing of the number of second film strips in the first horizontal direction to the second spacing. The spacing loading mechanism 6 is also configured to transfer the number of second film strips with the spacing adjusted to the top of the spacing supporting mechanism 1, so that the number of second film strips are vertically stacked on the number of first film strips.

[0097] The backplane transfer mechanism 7 is configured to transfer the backplane 100 to be coated to the spacing support mechanism 1, so that the plurality of second film strips and the plurality of first film strips are all attached to the lower surface of the backplane 100, wherein the length direction of the backplane 100 is parallel to the first horizontal direction, and the width direction of the backplane is parallel to the second horizontal direction.

[0098] The heating mechanism 2 is configured to press upward against and heat the plurality of second film strips and the plurality of first film strips, so that the plurality of second film strips and the plurality of first film strips are all attached to the lower surface of the back plate 100 .

[0099] The backplane transfer mechanism 7 is also configured to move the backplane 100 that has been coated with film strips away from the spacing support mechanism 1 .

[0100] It can be seen that through the cooperation of the spacing bearing mechanism 1, the heating mechanism 2, the first feeding mechanism 3, the film strip transfer mechanism 4, the second feeding mechanism 5, the spacing loading mechanism 6 and the backplane transfer mechanism 7, the backplane laminating device of the embodiment of the present application automatically applies a plurality of first film strips and a plurality of second film strips to the backplane 100 in a criss-cross manner, thereby improving the laminating efficiency.

[0101] The number of the first membrane strips and the number of the second membrane strips can be selected and set according to actual conditions. The number of the first membrane strips and the number of the second membrane strips can be equal or unequal.

[0102] As known to those skilled in the art, after the laminated photovoltaic module is completed, wiring needs to be done through the wiring holes prefabricated on the backplane. Figure 1 As shown, the wiring holes 101 are generally arranged in the middle of the back plate 100 and are arranged at intervals along the width direction of the back plate 100. In order to facilitate wiring, the wiring holes 101 will be located in the gaps of the battery string group, and the gaps of the battery string group need to be covered by the film strips attached to the back plate 100. Therefore, the film strips attached to the wiring holes 101 need to be punched to prevent the film strips from affecting the normal operation of the wiring holes 101.

[0103] In order to reduce the difficulty of punching holes in the film strip and avoid the wiring hole 101 being covered by the first film strip and the second film strip at the same time, the following solution can be used to avoid the wiring hole 101 when the first film strip is attached to the back plate 100. Figure 1 and Figure 2 As shown, optionally, the backplane coating device in the embodiment of the present application includes two first feeding mechanisms 3 spaced apart along the first horizontal direction, and the two first feeding mechanisms 3 are configured to synchronously supply a plurality of film strips extending along the first horizontal direction. The plurality of film strips supplied by the two first feeding mechanisms correspond to each other one by one, and the corresponding two film strips are located on the same straight line. The film strip transfer mechanism 4 is also configured to pick up two film strips located on the same straight line from the two first feeding mechanisms 3 to form a first film strip with a first avoidance gap in the middle.

[0104] For example, Fig.14 As shown, the two first feeding mechanisms 3 supply 5 film strips 201 respectively, and the corresponding two film strips 201 are located on the same straight line L, and the corresponding two film strips 201 constitute a first film strip 200 with a first avoidance gap 202 in the middle. Finally, the film strip transfer mechanism 4 places the five first film strips 200 with the first avoidance gap 202 in the middle onto the spacing support mechanism 1.

[0105] Thus, when the five first film strips 200 are attached to the lower surface of the back plate 100, the first avoidance gap 202 is aligned with the wiring hole 101 located in the middle of the back plate 100. That is, the wiring hole 101 on the back plate is exposed from the first avoidance gap 202, so that the first film strips 200 can be prevented from covering the wiring hole 101 on the back plate.

[0106] In addition, based on the size of the back panel 100 itself, the length of the back panel 100 is at least twice its width, and two first feeding mechanisms 3 and one second feeding mechanism 5 are used to supply the first film strip and the second film strip respectively. This also allows the first feeding mechanism 3 and the second feeding mechanism 5 to use the same material roll to output the film strip raw materials, which simplifies the production equipment and facilitates material changing. The first feeding mechanism 3 and the second feeding mechanism 5 can use the same mechanical structure to supply the film strips, and the material changing method is also the same, which reduces the workload of material changing and equipment maintenance.

[0107] Of course, only one first feeding mechanism 3 may be provided, and the first feeding mechanism 3 supplies a continuous first film strip having a length equivalent to that of the back plate 100. In order to prevent the first film strip from blocking the wiring holes on the back plate, a punching assembly may be used to punch an avoidance hole in the middle of the first film strip. After the first film strip is attached to the back plate 100, the wiring hole 101 is exposed from the avoidance hole in the middle of the first film strip.

[0108] In order to ensure that the wiring hole 101 can be exposed from the first avoidance gap 202 in the middle of the first film strip 200, and to avoid the first avoidance gap 202 being too large, so that the first film strip 200 cannot effectively cover the adhesive material on the backplane, the width of the first avoidance gap 202 needs to be set, for example, the width of the first avoidance gap 202 is set to 10mm. However, since the installation positions of the two first feeding mechanisms 3 are fixed, when the spacing between the film strips released by the two first feeding mechanisms 3 is not the same as the width of the first avoidance gap 202, it is necessary to adjust the spacing between the film strips supplied by the two first feeding mechanisms 3, so as to finally obtain the first film strip 200 with a first avoidance gap 202 of a predetermined width in the middle.

[0109] In order to adjust the spacing between the film strips supplied by the two first feeding mechanisms 3, optionally, the film strip transport mechanism 4 in the embodiment of the present application includes a bracket, a sliding drive, a lifting seat, a second lifting drive, a distance adjustment component and two adsorption components, wherein: the sliding drive is installed on the bracket, and the sliding drive is used to drive the lifting seat and the second lifting drive to slide back and forth along the second horizontal direction. The fixed end of the second lifting drive is installed on the sliding end of the sliding drive, the lifting seat is installed on the lifting end of the second lifting drive, the second lifting drive is used to drive the lifting seat to lift vertically, and the distance adjustment component is installed on the lifting seat. The two adsorption components are installed on the two moving ends of the distance adjustment component, and the distance adjustment component is used to adjust the spacing between the two adsorption components. The two adsorption components are configured to pick up a number of film strips from one first feeding mechanism respectively through negative pressure adsorption.

[0110] The working process of the film strip transfer mechanism is as follows:

[0111] The sliding drive first drives the two adsorption components to move to the two first feeding mechanisms 3, and then the second lifting drive drives the two adsorption components to descend to pick up a number of film strips respectively.

[0112] Next, the second lifting drive component drives the two adsorption components to lift and reset, and the sliding drive component then drives the two adsorption components to move to the distance bearing mechanism 1. During the movement, the distance adjustment component adjusts the distance between the two film strips on the same straight line to the first avoidance gap, thereby forming a first film strip.

[0113] The second lifting drive member then lowers the two adsorption components onto the spacing support mechanism 1 , and the two adsorption components place a plurality of first film strips on the spacing support mechanism 1 .

[0114] Of course, in the case where only one first feeding mechanism 3 is provided, the first feeding mechanism 3 supplies the first film strips of the same length as the back plate 100. Alternatively, by adjusting the installation spacing of the two first feeding mechanisms 3, the spacing between the film strips released by the two first feeding mechanisms 3 is equal to the first avoidance gap. The film strip transport mechanism 4 does not need to adjust the spacing of the film strips. At this time, optionally, the film strip transport mechanism 4 includes a driving part and an adsorption plate connected to the driving end of the driving part. The driving part is used to drive the adsorption plate to translate and lift, so as to drive the adsorption plate to absorb a plurality of first film strips from the first feeding mechanism 5, and release the picked-up plurality of first film strips to the spacing bearing mechanism 1.

[0115] like Figures 1 to 3 As shown, optionally, the first feeding mechanism 3 includes a discharge portion 31, a pressing portion 32, a clamping portion 33 and a slitting portion 34, wherein: the discharge portion 31 is configured to fix the film strip roll and drive the film strip roll to rotate, so as to deliver the film strip of a predetermined length to the pressing portion 32 along the second horizontal direction, and the pressing portion 32 is used to press the film strip of a predetermined length. The clamping portion 33 is configured to clamp the film strip of a predetermined length located on the pressing portion from both sides, and move the film strip of a predetermined length to the slitting portion 34 along the second horizontal direction. The slitting portion is configured to slit the film strip of a predetermined length along the first horizontal direction to obtain a plurality of film strips. The film strip transfer mechanism 4 is configured to simultaneously pick up a plurality of film strips from the slitting portions 34 of the two first feeding mechanisms 3, so that a plurality of first film strips consisting of two film strips with a first avoidance gap in the middle can be obtained.

[0116] Optionally, the pressing part 32 includes a lower pressing plate 321 and an upper pressing plate 322, the unloading part 31 delivers the film tape of a predetermined length to the lower pressing plate 321 along the second horizontal direction, and the upper pressing plate 322 presses the film tape of a predetermined length onto the lower pressing plate 321. Both ends of the film tape of a predetermined length extend outward from the upper pressing plate 322 and the lower pressing plate 321. The clamping part 33 is configured to clamp the film tape of a predetermined length extending outward from both ends of the lower pressing plate 321 from both sides.

[0117] It can be seen that the pressing part 32 can press the film strip of predetermined length by the cooperation of the lower pressing plate 321 and the upper pressing plate 322. In addition, by setting the length of the lower pressing plate 321 and the upper pressing plate 322 in the first horizontal direction, both ends of the film strip of predetermined length can extend outward from the upper pressing plate 322 and the lower pressing plate 321, so that the clamping part 33 can clamp both ends of the film strip of predetermined length from both sides, which is convenient for subsequent slitting.

[0118] Optionally, the clamping portion 33 includes two groups of symmetrically arranged clamping assemblies, each group of clamping assemblies is configured to clamp the end of the predetermined length of the film strip on the pressing portion 32 from one side, and move the clamped predetermined length of the film strip to the slitting portion 34 along the second horizontal direction. Figure 4As shown, each group of clamping assemblies includes a first translation driving module 331 and a plurality of clamping jaws 332 arranged on the first translation driving module at intervals along the second horizontal direction, wherein: the first translation driving module 331 is configured to drive the plurality of clamping jaws 332 to translate between the pressing portion 32 and the slitting portion 34, and the plurality of clamping jaws 332 are configured to clamp one end of a film strip of a predetermined length together, and a second avoidance gap 333 is formed between two adjacent clamping jaws 332. When the slitting portion 34 slits the film strip of a predetermined length along the first horizontal direction, the second avoidance gap 333 is used for the blade of the slitting portion to pass through, thereby ensuring that the slitting portion 34 can implement slitting of the end of the film strip of a predetermined length clamped by the clamping portion 33.

[0119] The first translation drive module 331 can adopt various existing linear drive modules that can drive the plurality of clamping jaws 332 to translate between the clamping portion 32 and the cutting portion 34, such as a screw drive module composed of a motor, a screw, and a screw nut.

[0120] like Figure 5 to Figure 6 As shown, optionally, the cutting part 34 includes a cutting plate 341, a second translation driving module 342, a lifting driving module 343 and a cutting knife assembly 344, wherein: a plurality of convex strips 345 are arranged at intervals along the second horizontal direction on the cutting plate 341, the convex strips 345 extend along the first horizontal direction, and a cutting groove is formed between two adjacent convex strips 345. The lifting driving module 343 is connected to the driving end of the second translation driving module 342, and the cutting knife assembly 344 is connected to the driving end of the lifting driving module 343. The cutting knife assembly 344 includes a plurality of blades 346 arranged at intervals along the second horizontal direction and corresponding to the cutting grooves one by one, and each blade 346 is located directly above the corresponding cutting groove.

[0121] The clamping portion 33 is configured to translate the film strip of a predetermined length onto the cutting plate 341 along the second horizontal direction. The lifting drive module 342 is configured to drive the cutter assembly 344 to descend, so that each blade 346 presses the film strip of a predetermined length into the slitting groove from the corresponding position. Subsequently, the second translation drive module 342 drives the cutter assembly to translate along the first horizontal direction, thereby driving each blade 346 to move along the corresponding slitting groove to cut the film strip of a predetermined length into a plurality of film strips. The film strip transport mechanism 4 is configured to pick up a plurality of film strips from the cutting plate 341. The second translation drive module 342 and the lifting drive module 343 can both adopt various types of existing linear drive modules.

[0122] It can be seen that the cutter assembly 344 can cut the film tape of a predetermined length carried on the cutting plate 341 into a plurality of film strips at one time, thereby improving the cutting efficiency. In addition, since the cutting plate 341 is provided with cutting grooves corresponding to the blades 346, the blades 346 cut the film tape along the corresponding cutting grooves, thus preventing the blades 346 from going off track and ensuring the cutting effect.

[0123] Continue to refer Figure 5 to Figure 6 As shown, optionally, the slitting portion 34 also includes an upper pressing assembly 347 that is transmission-connected to the driving end of the lifting driving module 343. The upper pressing assembly 347 includes pressure strips 348 that are arranged at intervals along the second horizontal direction and correspond to the convex strips 345 one by one. The pressure strips 348 extend along the first horizontal direction, and each pressure strip 348 is located directly above the corresponding convex strip 345. There is a blade 346 between two adjacent pressure strips 348, and the blade 346 extends downward from the pressure strip 348.

[0124] The lifting drive module 343 is configured to drive the upper pressure assembly 347 and the cutter assembly 344 to descend synchronously. When each blade 346 presses a film tape of a predetermined length into the corresponding cutting groove from a corresponding position, each pressure strip 348 presses the film tape of a predetermined length onto the corresponding convex strip 345 from a corresponding position.

[0125] By setting the upper pressing assembly 327 and setting the upper pressing assembly 247 to keep the pressing strips 348 corresponding to the convex strips 345, it can be realized that the pressing strips 348 and the convex strips 345 cooperate to press the film strip from both sides of each blade 346, so as to ensure that when the blade 346 cuts the film strip, the cutting position of the film strip will not be wrinkled, and finally ensure that the obtained film strip has neat edges on both sides.

[0126] like Figures 10 to 12 As shown, optionally, the backplane laminating device in the embodiment of the present application includes only one second feeding mechanism 5, and the structure of the second feeding mechanism 5 is the same as the structure of the first feeding mechanism 3 in the previous embodiment. The backplane laminating device in the embodiment of the present application also includes a transfer table 8. The clamping portion 33 of the second feeding mechanism 5 is also configured to transfer a plurality of second film strips from the cutting portion 34 of the second feeding mechanism 5 to the transfer table 8, and the two ends of the second film strips extend out of the transfer table 8. The spacing feeding mechanism 6 includes two groups of symmetrically arranged spacing feeding components, and the two groups of spacing feeding components are configured to pick up the two ends of a plurality of second film strips from both sides of the transfer table 8, respectively.

[0127] The two sets of spacing loading components are configured to pick up the two ends of several second film strips from both sides of the transfer table 8 and place the several second film strips on the spacing supporting mechanism 1. During this process, the two sets of spacing loading components can avoid the spacing supporting mechanism 1 to prevent contact with the spacing supporting mechanism 1.

[0128] Optionally, the backplane coating device in the embodiment of the present application further includes a drilling assembly, which includes a lifting plate, a first lifting drive and three drilling members, wherein: the three drilling members are installed in parallel on the lifting plate along the second horizontal direction, the first lifting drive is used to drive the lifting plate to lift, the lifting plate is located above the clamping portion 32 of the second feeding mechanism 5, and three first avoidance holes are provided on the upper pressing plate 322 and the lower pressing plate 321 of the clamping portion 32, and each first avoidance hole is located directly below a drilling member. After the clamping portion 32 of the second feeding mechanism 5 clamps the film tape of a predetermined length, the first lifting drive drives the three drilling members to pass through the clamping portion 32 and the film tape to drill holes in the film tape, and the holes on the film tape correspond to the wiring holes arranged at intervals along the second horizontal direction at the middle position of the backplane.

[0129] In this way, it can be ensured that after the film strip is cut, the second film strip at the most middle position has a avoidance through hole corresponding to the wiring hole at the middle position of the back plate. When a plurality of second film strips are attached to the back plate, the wiring hole at the middle position of the back plate can be exposed from the second film strip through the avoidance through hole to prevent being blocked by the second film strip.

[0130] like Fig.12 As shown, optionally, both sets of spacing feeding components include a moving unit (not shown in the figure), a mounting seat 61, a guide rail 62, a spacing driving unit 63, and a plurality of second spacing clamps 64 corresponding to the second film strips, wherein: the mounting seat 61 is arranged on the moving unit, the guide rail 62 is installed on the mounting seat 61 along the first horizontal direction, and the plurality of second spacing clamps 64 are installed on the guide rail 62. The moving unit is configured to drive the mounting seat 61 to move toward the transfer table 8, so that the plurality of second spacing clamps 64 respectively clamp one end of a corresponding second film strip located on the transfer table 8. The spacing driving unit 63 is arranged on the mounting seat 61, and the spacing driving unit 63 is configured to drive the plurality of second spacing clamps 64 to slide and separate along the guide rail 62, so as to adjust the spacing of the plurality of second film strips to the second spacing.

[0131] It can be seen that the spacing feeding assembly drives a plurality of second spacing jaws 64 to move along the guide rail 62 through the spacing driving unit 63, so that the second film strips clamped by the plurality of second spacing jaws 64 can be automatically spaced. The overall structure is simple and the film strip spacing action is stable.

[0132] Optionally, among the plurality of second spacing jaws 64, the second spacing jaws located at the first end are fixedly mounted on the guide rail 62, and the remaining second spacing jaws 64 are slidably mounted on the guide rail 62, and adjacent second spacing jaws 64 are connected by flexible parts, and the second spacing jaws 64 located at the second end are transmission connected to the spacing driving unit 63. When the spacing driving unit 63 drives the second spacing jaws located at the second end to slide along the guide rail, the remaining second spacing jaws 64 except the second spacing jaw 64 located at the first end are driven to slide along the guide rail 62 through the flexible parts, so as to adjust the spacing of the plurality of second membrane strips to the second spacing.

[0133] Optionally, the spacing driving unit 63 includes a synchronous belt 631 disposed on the mounting seat 61 along the first horizontal direction, and a second spacing clamping claw 64 located at the second end is fixedly connected to a side belt body (eg Fig.13 On the lower belt body shown in the figure, the synchronous belt rotates under the drive of the driving motor 632, thereby driving the second spacing clamping claw 64 located at the second end to slide along the guide rail 62.

[0134] Of course, the two sets of spacing loading components can also adopt other spacing structures. For example, in another optional embodiment, the two sets of spacing components include a transmission belt and a driving component arranged along the first horizontal direction, and a plurality of first spacing clamps corresponding to the second film strips are installed on the transmission belt at equal distances, and the spacing between two adjacent first spacing clamps is equal to the second spacing. The driving component is configured to drive the transmission belt to slide cyclically along the first horizontal direction to drive the plurality of first spacing clamps to pass through the material-retrieving end on one side of the transfer table 8 in turn, so that each first spacing clamp respectively clamps one end of the corresponding first film strip located on the transfer table. After the plurality of second film strips are moved to the top of the spacing support mechanism 1 driven by the plurality of first spacing clamps, the first spacing clamps release the second film strips so that the second film strips fall on the spacing support mechanism 1.

[0135] In order to ensure that the first spacing clamping claw can clamp one end of the first film strip located on the transfer table, the transfer table 8 is also configured to sequentially deliver a plurality of second film strips to the material taking end of the spacing loading assembly.

[0136] like Figures 7 and 8 As shown, optionally, the spacing bearing mechanism 1 includes a spacing driving unit 12 and a plurality of adsorption strips 11 arranged side by side along the second horizontal direction, and the adsorption strips 11 extend along the first horizontal direction. Each adsorption strip 11 is used to carry and adsorb a first film strip. The spacing driving unit 12 is used to drive the plurality of adsorption strips 11 to separate along the second horizontal direction, so as to adjust the spacing between the plurality of first film strips to the first spacing.

[0137] In addition, the adsorption strip 11 is further provided with a second avoidance hole penetrating the adsorption strip 11 in the vertical direction, and the heating mechanism 21 is configured to heat the first film strip through the second avoidance hole.

[0138] The separation driving unit 12 can adopt various existing separation driving mechanisms that can drive a plurality of adsorption strips 11 to separate along the second horizontal direction. For example, the separation driving unit 12 includes a slide rail arranged along the second horizontal direction, and a driving member. Among the plurality of adsorption strips 11, the adsorption strip 11 located at the first end is fixed on the slide rail, and the remaining adsorption strips 11 are slidably connected to the slide rail. Adjacent adsorption strips 11 are connected via flexible members, and the driving end of the driving member is in transmission connection with the adsorption strip 11 located at the second end.

[0139] In the initial state, several adsorption strips 11 are close to each other. When the film strip transfer mechanism 4 places several first film strips one by one on the adsorption strips 11, the driving member drives the adsorption strip 11 at the second end connected to it to move away from the adsorption strip 11 at the first end fixed on the slide rail, thereby driving the remaining adsorption strips 11 except the adsorption strip 11 at the first end to slide along the slide rail through the flexible member, and finally adjusting the spacing of the several first film strips to the first spacing.

[0140] like Figures 7 to 9 As shown, optionally, the heating mechanism 2 includes a plurality of heating components 21, each heating component 21 includes a third lifting drive member 211 and a heating head 212, wherein: the plurality of heating components 21 are respectively located below corresponding preset heating points of the plurality of first film strips and the second film strips, and the third lifting drive member 211 of each heating component 21 is used to drive the heating head 212 to rise and abut against the preset heating point on the corresponding first film strip or the second film strip, so that the plurality of first film strips and the second film strips are attached to the lower surface of the back panel 100.

[0141] Since the first film strip is located on the adsorption strip 11, by setting the size of the heating head 212 to match the size of the second avoidance hole on the adsorption strip 11, it can be ensured that the heating head 212 passes through the second avoidance hole upward, thereby achieving contact heating of the first film strip.

[0142] In addition, by setting the number and position of the heating components 21, all the first film strips and the second film strips to be coated can be coated to the lower surface of the back plate by contact heating at one time, thereby improving the coating efficiency.

[0143] Of course, the heating mechanism 2 may also adopt other implementation structures. For example, in another optional embodiment, the heating mechanism includes a lifting drive unit, a support plate and a plurality of heating heads, wherein: the support plate is horizontally connected to the lifting end of the lifting drive unit, and the plurality of heating heads are arranged on the support plate. When the lifting drive unit drives the support plate to rise, each heating head performs contact heating on the first film strip or the second film strip, so that the first film strip and the second film strip are attached to the lower surface of the back plate. In addition, by setting the number and position of the heating heads, it is possible to attach all the first film strips and the second film strips to be attached to the lower surface of the back plate at one time, thereby improving the coating efficiency.

[0144] like Figure 1 As shown, optionally, the backplane transfer mechanism 7 includes a first transfer part 71 and a second transfer part 72, wherein the first transfer part 71 is used to transport the backplane 100 to be coated to the spacing carrier mechanism 1, and the second transfer part 72 is used to move the backplane 100 coated with film strips away from the spacing carrier mechanism 1.

[0145] In particular, when the second transfer unit 72 moves the back panel 100 coated with the film strips away from the spacing support mechanism 1, the first transfer unit 71 can simultaneously move another back panel 100 to be coated to the spacing support mechanism 1, thereby speeding up the work cycle and improving the coating efficiency.

[0146] Optionally, the backplane coating device in the embodiment of the present application further includes a backplane conveyor line and a battery assembly conveyor line, wherein: the backplane conveyor line is configured to convey the backplane to be coated, and a loading station E close to the spacing bearing mechanism is provided on the conveying path of the backplane conveyor line, and the backplane transfer mechanism 7 is configured to pick up the backplane 100 to be coated from the loading station E, and transfer the picked up backplane 100 to be coated to the spacing bearing mechanism 1. The battery assembly conveyor line is configured to convey battery assemblies, and the battery assembly conveyor line passes under the spacing bearing mechanism 1, and a unloading station 6 close to the spacing bearing mechanism 1 is provided on the conveying path of the battery assembly conveyor line, and the backplane transfer mechanism 7 stacks the backplane with film strips removed from the spacing bearing mechanism 1 onto the battery assembly located at the unloading station F, wherein the battery assembly includes a bottom plate and a battery string group laid on the bottom plate.

[0147] By setting up a backplane conveyor line, the backplane to be coated can be automatically conveyed to the loading station E close to the supporting mechanism, so that the backplane transfer mechanism 7 can obtain the backplane to be coated nearby and transfer the backplane to be coated to the spacing supporting mechanism 1, thereby ensuring the working rhythm and improving the coating efficiency.

[0148] By setting up a battery assembly conveyor line, the battery assembly with the back panel to be stacked can be automatically conveyed to the unloading station F close to the supporting mechanism, so that the back panel transfer mechanism 7 can stack the back panel with the film strip coated on the battery assembly nearby, so that the battery assembly can complete the stacking of the back panel during the conveying process.

[0149] The present application is described in sufficient detail above with certain particularity. It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, rather than by the above description in the embodiments.
