Detailed Implementation

[0034] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0035] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0037] Please refer to Figures 1 to 7This application embodiment of the coating pad device includes a base 1, a coating pad 2, a pad paper assembly 3, a limiting assembly 4, and a fixing assembly 5. The coating pad 2 is disposed on the base 1. The pad paper assembly 3 includes a pad paper component 301 and support rods 302. The pad paper component 301 covers the surface of the coating pad 2 in a first direction. There are two support rods 302, symmetrically fixed on both sides of the pad paper component 301 in a second direction, and both support rods 302 extend along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The limiting assembly 4 is disposed on the base 1, and is correspondingly disposed to each support rod 302. The limiting assembly 4 is used to limit the corresponding support rod 302 in the second direction and also to limit the corresponding support rod 302 in the third direction. The fixing component 5 is located on the base 1. The fixing component 5 and the support rod 302 are respectively set one-to-one. The fixing component 5 and the corresponding support rod 302 are detachably connected. The fixing component 5 is used to fix the corresponding support rod 302 between the fixing component 5 and the base 1.

[0038] In this embodiment, two support rods 302 are symmetrically fixed on both sides of the ink pad paper 301 in the second direction and extend along the third direction. This can effectively tension the ink pad paper 301, prevent the ink pad paper 301 from curling, and make it easier to fix the ink pad paper 301 onto the coating ink pad 2. The limiting component 4 can limit the ink pad paper assembly 3 in the second direction and the third direction, thereby quickly and accurately positioning the ink pad paper assembly 3 onto the base 1. Moreover, the support rods 302 can be fixed between the fixing component 5 and the base 1 by means of the fixing component 5 which is detachably connected to the support rods 302. This not only effectively fixes the ink pad paper assembly 3 and prevents the ink pad paper assembly 3 from moving accidentally, but also facilitates the loading and unloading of the ink pad paper assembly 3.

[0039] As one implementation method, please refer to Figure 1 and Figure 2 The coating pad 2 may include a plurality of pad glass 201 spaced apart in a third-direction upward direction, with a first gap 202 between adjacent pad glass 201. Each pad glass 201 has a vacuum adsorption hole 2011 for adsorbing the battery cell. Accordingly, please refer to Figure 4 and Figure 7The inkpad paper component 301 has cutouts 3011 that correspond one-to-one with the first interval 202, thus dividing the inkpad paper component 301 into multiple paper segments 3012. Each paper segment 3012 corresponds one-to-one with the inkpad glass 201, and each paper segment 3012 covers the surface of the corresponding inkpad glass 201. To facilitate installation and ensure the structural stability of the inkpad paper component 301, all paper segments 3012 are connected at one end in the second direction and at the other end in the second direction. That is to say, the cutouts 3011 do not penetrate the inkpad paper component 301 in the second direction, and the paper segments 3012 are not independent of each other. Please refer to [reference needed]. Figure 7 .

[0040] In one implementation, the ink pad paper component 301 can be detachably connected to the support rod 302, so that the support rod 302 can be reused multiple times, and only the ink pad paper component 301 needs to be replaced.

[0041] As an example, please refer to Figure 6 The support rod 302 may include a first part 3021 and a second part 3022. The first part 3021 and the second part 3022 are arranged sequentially along a first direction, and one end of the first part 3021 and the second part 3022 are hinged together in a second direction. The first part 3021 and the second part 3022 can rotate relative to each other to open or close. The closed first part 3021 and the second part 3022 can be detachably fixed by fasteners such as screws (not shown). The first part 3021 has a first clamping surface 30211 facing the second part 3022, and the second part 3022 has a second clamping surface 30221 facing the first part 3021. The ink pad paper 301 is clamped between the first clamping surface 30211 and the second clamping surface 30221. This design is not only simple in structure but also facilitates the replacement of the ink pad paper 301.

[0042] It should be noted that in other embodiments, the support rod 302 can also be other structures, which can be set according to the actual situation, and will not be described in detail here.

[0043] In some implementation methods, please refer to Figure 1 and Figure 4 Two support rods 302 are constrained between two limiting components 4. Each support rod 302 has two ends 3023, which are arranged opposite each other in a third direction. The limiting components 4 include two limiting members 401, each corresponding to one of the ends 3023 of the corresponding support rod 302. The limiting members 401 not only constrain the corresponding ends 3023 in a second direction, but also in a third direction.

[0044] In this embodiment, the four limiting members 401 of the two limiting components 4 cooperate with each other to limit the two support rods 302 of the ink pad paper assembly 3 in the second direction and the third direction. Not only is the structure simple, but the support rods 302 can be quickly and accurately positioned on the base 1. Moreover, when replacing the ink pad paper assembly 3, it is convenient to remove the ink pad paper assembly 3 from between the two limiting components 4, and the disassembly is convenient.

[0045] In some implementation methods, please refer to Figure 1 The limiting member 401 includes a first limiting portion 4011 and a second limiting portion 4012. The first limiting portion 4011 extends along a second direction, and the second limiting portion 4012 is fixed to one end of the first limiting portion 4011 and extends along a third direction. The support rod 302 is constrained in the second direction between the coating pad 2 and the corresponding second limiting portion 4012. For example, the second limiting portion 4012 and the coating pad 2 are spaced apart in the second direction to form a limiting space, and the end 3023 of the support rod 302 is constrained within the corresponding limiting space. The support rod 302 is restricted in the third direction between the two first limiting portions 4011 of the corresponding limiting component 4. For example, the first limiting portions 4011 of the two limiting members 401 of the same limiting component 4 are spaced apart in the third direction, and the support rod 302 is disposed between the two first limiting portions 4011. One end 3023 of the support rod 302 can abut against one of the first limiting portions 4011 in the third direction, and the other end 3023 of the support rod 302 can abut against the other first limiting portion 4011 in the third direction.

[0046] In one embodiment, the support rod 302 can abut against the corresponding second limiting part 4012 in the second direction, thereby making the support rod 302 and the second limiting part 4012 fit more tightly and improving the stability of the overall structure.

[0047] In another embodiment, the support rod 302 may have a gap with the corresponding second limiting part 4012 in the second direction. After prolonged use, the support rod 302 may bend and deform, causing the end 3023 of the support rod 302 to interfere with the second limiting part 4012 when the inkpad paper 301 is tensioned, preventing the end 3023 of the support rod 302 from being inserted into the corresponding limiting space. Therefore, a certain gap can be reserved between the second limiting part 4012 and the corresponding support rod 302, allowing the deformed support rod 302 to be inserted into the corresponding limiting space, thus facilitating installation.

[0048] As an example, the limiting member 401 can be detachably fixed to the base 1 by fasteners such as screws (not shown). When it is necessary to adjust the gap between the second limiting part 4012 and the support rod 302, the screw can be removed first, and then the limiting member 401 can be moved in the second direction away from the coating pad 2, thereby increasing the gap between the second limiting part 4012 and the end 3023 of the support rod 302. Alternatively, when it is necessary to adjust the gap between the second limiting part 4012 and the support rod 302, the screw can be loosened or removed first, and then the second limiting part 4012 can be rotated about the first axis, thereby increasing the gap between the second limiting part 4012 and the end 3023 of the support rod 302. The first axis is parallel to the first direction. In some examples, the first axis can be the axis of the screw that fixes the limiting member 401 and the base 1, which can be set according to the actual situation, and will not be described in detail here.

[0049] In some implementation methods, please refer to Figure 1 and Figure 2 The coating pad device also includes four sensors 6, which are fixed to the base 1. The sensors 6 are arranged in a one-to-one correspondence with the ends 3023 of the support rods 302. The sensors 6 can be used to sense whether the ends 3023 of the corresponding support rods 302 are installed in place. This not only improves the assembly accuracy, but also avoids poor coating caused by poor assembly of the paper pad assembly 3, and further improves the product yield of solar cells.

[0050] As an example, the sensing element 6 can be a proximity metal sensor, which can quickly and effectively detect whether the end 3023 of the support rod 302 is installed in place. This can not only improve the assembly accuracy, but also avoid poor coating caused by poor assembly of the ink pad paper assembly 3, thereby further improving the product yield of solar cells.

[0051] In some implementation methods, please refer to Figure 1 and Figure 2 The fixing component 5 includes multiple fixing members 501, all of which are arranged sequentially at intervals in the third direction. Each fixing member 501 is detachably connected to the corresponding support rod 302, which not only facilitates loading and unloading, but also makes the support rod 302 more uniformly stressed and can more stably and effectively fix the support rod 302 and the ink pad paper 301, further achieving uniform and stable clamping of the edge of the ink pad paper 301.

[0052] As an example, please refer to Figure 3The fastener 501 may include a first locking portion 5011 and a second locking portion 5012, which are detachably connected. The first locking portion 5011 is fixed to one side of the base 1 in a second direction. One end of the first locking portion 5011 is fixed to the base 1, and the other end of the first locking portion 5011 is bent and extended. The second locking portion 5012 includes a first hook body 50121 and a second hook body 50122. The first hook body 50121 includes a connecting arm 501211 and a hook arm 501212. One end of the connecting arm 501211 is rotatably connected to the base 1, and the hook arm 501212 is bent and extended from the other end of the connecting arm 501211. The connecting arm 501211 is rotatable about a second axis 7, which is parallel to a third direction. The second hook 50122 is rotatably connected to the connecting arm 501211, and is positioned close to the hook arm 501212. The second hook 50122 can rotate about a third axis 8, which is parallel to the third axis. Specifically, the first hook 50121 can rotate about a second axis 7, allowing the hook arm 501212 to be detachably hooked onto the side of the support rod 302 facing away from the base 1 in the first direction. The second hook 50122 can rotate about the third axis 8, allowing it to be detachably hooked onto the first locking part 5011. When the hook arm 501212 is hooked onto the side of the support rod 302 facing away from the base 1 in the first direction, and the second hook 50122 is hooked onto the first locking part 5011, the support rod 302 is securely fixed between the fixing member 501 and the base 1.

[0053] It should be noted that in other embodiments, the fastener 501 can also be other structures, which can be set according to the actual situation, and will not be described in detail here.

[0054] In some implementation methods, please refer to Figure 1 and Figure 2 The coating pad device also includes a support assembly 9, which is disposed on the base 1, and the support assembly 9 is correspondingly arranged with the support rod 302. The support assembly 9 is used to support the corresponding support rod 302 in a first direction. That is, in the first direction, the support rod 302 is pressed between the corresponding support assembly 9 and the corresponding fixing assembly 5.

[0055] As one implementation method, please refer to Figure 1 and Figure 2 The support assembly 9 includes a plurality of support members 901, all of which are arranged sequentially at intervals in a third direction. The side surface of the support member 901 facing away from the base 1 in a first direction is constructed as a support surface 9011, which is used to support the support rod 302.

[0056] As an example, please refer to Figure 2 As shown, the height of the support rod 302 supported on the support member 901 in the first direction is lower than the height of the coating pad 2 in the first direction, so that the paper part 301 of the pad can be tensioned more effectively.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above embodiments merely illustrate preferred implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
