[0035] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0036] This embodiment relates to a glue liquid scraping and coating device, which can ensure the mask width and the thickness of the glue liquid coating.

[0037] In terms of the overall structure, as Figures 1 to 3 shown, the glue liquid scraping and coating device of this embodiment includes a mounting frame 1, and a glue coating component and a mask plate assembly 2 provided on the mounting frame 1.

[0038] Among them, a positioning groove 100 for positioning the component 10 to be coated with glue is provided on the mounting frame 1, and the depth of the positioning groove 100 is consistent with the thickness of the component 10 to be coated with glue. The glue coating component has a glue coating plate 31 that can move above the component 10 to be coated with glue, and the glue coating plate 31 is used for coating the component 10 to be coated with glue.

[0039] The mask plate assembly 2 includes a plurality of mask plates 22 arranged circumferentially on the component 10 to be coated with glue. Each mask plate 22 can rotate between a first position and a second position on the mounting rack 1. When each mask plate 22 is in the first position, it presses on the edge of the component 10 to be coated with glue. When in the second position, the pressing on the component 10 to be coated with glue is released. And each mask plate 22 has a shielding end 222 that shields the edge of the component 10 to be coated with glue, and a contact end 221 that abuts against the glue coating plate 31. The width of the shielding end 222 defines the mask width, and the distance between the shielding end 222 and the contact end 221 defines the thickness of the glue solution coated on the component 10 to be coated with glue.

[0040] At this time, in the above structure, the plurality of mask plates 22 arranged circumferentially on the component 10 to be coated with glue can cover the circumferential edge of the component 10 to be coated with glue. Each mask plate 22 can rotate between the first position and the second position, which is conducive to the mask plate 22 shielding the edge of the component 10 to be coated with glue in the first position, and when the mask plate 22 is in the second position, it is convenient for the taking and placing of the component 10 to be coated with glue. The depth of the positioning groove 100 is consistent with the thickness of the component 10 to be coated with glue, and it cooperates with the shielding end 222 and the contact end 221 of the mask plate 22, so as to ensure the thickness of the glue solution coated on the component 10 to be coated with glue and the mask width, thus being conducive to improving the glue coating quality. Among them, the mask width is also the distance from the circumferential edge of the glue solution film layer to the circumferential edge of the component 10 to be coated with glue.

[0041] Specifically, continuing to refer to Figures 1 to 3 As shown, as a preferred embodiment, in this embodiment, a mounting base 21 is provided on the mounting rack 1. The mounting base 21 can be fixedly connected to the mounting rack 1 by welding or screwed to the mounting rack 1. And a positioning groove 100 for positioning the placed component 10 to be coated with glue is provided on the mounting base 21. And each of the above-mentioned circumferentially arranged mask plates 22 is rotatably arranged on the mounting base 21.

[0042] It should be noted that the first position of each mask plate 22, that is, the position where the shielding end 222 shields the edge of the component 10 to be coated with glue. At this time, the end face of the shielding end 222 is attached to the upper surface of the component 10 to be coated with glue. The second position of each mask plate 22, that is, the position of releasing the pressing on the component 10 to be coated with glue. And preferably, the mask plate 22 is in the position after being flipped 145° from the first position. At this time, the angle between the plane where the first position is located and the plane where the second position is located is 145°. It can be understood that the angle between the plane where the first position is located and the plane where the second position is located can also be set to 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 160° or 180°, etc., and this is also feasible.

[0043] In addition, it is also worth noting that the member 10 to be coated with glue in this embodiment is preferably a solar cell module, and the coated glue is used for the encapsulation between the solar cell module and the backplane. It can be understood that the member 10 to be coated with glue in this embodiment can also be other components or films that require glue coating in addition to being a solar cell module.

[0044] In this embodiment, in addition to being configured as the above-mentioned integral structure, the mounting base 21 can also be a split structure, that is, the mounting base 21 is a plurality of circumferentially arranged ones. Specifically, as another preferred implementation manner, in this embodiment, referring to Figure 3 、 Figure 4 and in combination with Figure 1 as shown, the mask assembly includes a plurality of mounting bases 21 provided on the mounting frame 1, and each mounting base 21 encloses a positioning groove 100. Moreover, a plurality of mask plates 22 are arranged in one-to-one correspondence with the plurality of mounting bases 21, and each mask plate 22 is rotatably provided on the corresponding mounting base 21. At this time, the mounting base 21 and the mask plate 22 are provided in a plurality of one-to-one correspondences, so that the mask plate 22 and the mounting base 21 are connected to form an assembly, and then the assembly is mounted on the mounting frame 1. This structure is relatively simple and has a low cost.

[0045] In this embodiment, the mounting base 21 and the mask plate 22 are preferably four groups, and each group is arranged around the member 10 to be coated with glue. In addition, as a preferred implementation manner, in this embodiment, each mounting base 21 is detachably connected to the mounting frame 1, which is beneficial to the installation and replacement of the mounting base 21 and the mask plate 22. In specific implementation, between each mask plate 22 and the mounting base 21, they can be connected together through, for example, hinges, hinge shafts, or rotating members capable of adjusting the flipping angle, so as to enable each mask plate 22 to be preferably maintained in the first position and the second position.

[0046] As a preferred implementation form, in this embodiment, the glue coating plate 31 can slide along the length direction of the member 10 to be coated with glue to scrape the glue coated on the member 10 to be coated with glue. In this way, the glue coated on the member 10 to be coated with glue can be scraped flat by the movement of the glue coating plate 31, thereby improving the uniformity of the glue film surface. It is worth noting here that the glue coating plate 31 can also slide along the width direction of the member 10 to be coated with glue, and in this way, the glue can also be scraped flat.

[0047] In terms of the specific structure, referring to Figures 1 to 3As shown in the figure, in this embodiment, a support frame 3, a first driving device, and a second driving device are provided on the mounting frame 1. Among them, the support frame 3 can be lifted and lowered along the height direction of the mounting frame 1 under the drive of the first driving device, and the support frame 3 can slide along the length direction of the component 10 to be coated under the drive of the second driving device. The above-mentioned glue application plate 31 is specifically arranged on the support frame 3, and the glue outlet 310 of the glue application plate 31 faces the component 10 to be coated, so that the glue liquid at the glue outlet 310 can be smoothly coated on the component 10 to be coated.

[0048] At this time, the setting of the support frame 3 is beneficial to the layout and installation of the glue application plate 31. And the support frame 3 can be lifted and lowered along the height direction of the mounting frame 1 under the drive of the first driving device. When in a lower position, it is beneficial to the smooth progress of glue application. When in an upper position, it can leave a clearance space above the component 10 to be coated, which is convenient for the taking and placing of the component 10 to be coated. Moreover, the support frame 3 can slide along the length direction of the component 10 to be coated under the drive of the second driving device, which is beneficial to improving the automation degree of the scraping operation and the glue application efficiency.

[0049] To facilitate the smooth sliding of the glue application plate 31 on the mask plate 22, in this embodiment, rolling members are provided at the bottom of the glue application plate 31 for contacting the abutting ends 221 on the corresponding mask plate 22. At this time, the setting of the rolling members can reduce the friction force when the glue application plate 31 moves relative to the abutting ends 221, and ensure the smooth sliding of the glue application plate 31 along the abutting ends 221.

[0050] Preferably, in the normal direction of the component 10 to be coated, the rolling members are elastically connected to the bottom end of the glue application plate 31, so that the rolling members elastically press on the abutting ends 221, aiming to prevent the mask plate 22 from jumping and ensure that the shielding ends 221 always closely adhere to the surface of the component 10 to be coated.

[0051] During specific implementation, the rolling members include rollers 311 arranged at the bottom of the glue application plate 31. The rollers 311 are elastically in contact with the abutting ends 221. At this time, when the glue application plate 31 moves along the glue application direction, the rollers 311 roll on the abutting ends 221 and elastically press on the abutting ends 221, thereby effectively preventing the mask plate 22 from jumping. In this embodiment, the rolling members adopt rollers 311, which have a simple structure and are convenient for design and installation. It can be understood here that multiple balls can also be arranged on the abutting ends 221. At this time, by abutting the balls against the bottom of the glue application plate 31, the friction force when the glue application plate 31 moves can also be reduced.

[0052] In addition, in this embodiment, a glue liquid recovery box 4 for collecting the redundant glue liquid coated on the workpiece 10 to be glued is also provided on the mounting rack 1. The provision of the glue liquid recovery box 4 can collect the redundant glue liquid coated during the scraping process of the glue coating plate 31. Specifically, the glue liquid recovery box 4 can be arranged on the side of the mounting rack 1 and located on the scraping path of the glue coating plate 31, so as to collect the redundant glue liquid better.

[0053] The glue scraping device of this embodiment can not only ensure the mask width and the thickness of the glue coating on the workpiece 10 to be glued, improve the glue coating quality, but also improve the uniformity of the glue coating on the battery module when applied to the solar cell module, ensure the mask width and the thickness of the glue coating of the battery module, and can also solve the problems such as lack of glue on the appearance of the battery module after lamination, thus facilitating the improvement of the stability and service life of the battery module.

[0054] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
