[0002] In the manufacturing process of photovoltaic modules, encapsulation is a crucial step, and the adhesive film plays an indispensable role as an encapsulation material. During the laying process of the adhesive film, due to its soft characteristics, an adsorption device usually composed of multiple suction nozzles adsorbs the adhesive film and lays it on a substrate. However, the adsorption force at the suction nozzles of the adsorption device is relatively concentrated and strong, while the adsorption force between adjacent suction nozzles is relatively weak, resulting in the adhesive film being in a wavy shape during the adsorption process, as Figure 1 shown.

[0038] The preferred implementation manners of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners 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.

[0039] It should be noted that in the description of the present application, the terms indicating the direction or positional relationship such as "upper", "lower", "inner", "bottom", etc. are based on the direction or positional relationship shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0040] In addition, it should be noted that in the description of the present application, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0041] As Figure 1 shown, in the prior art, the adsorption device includes a plurality of nozzles 4. However, the adsorption force at the nozzle 4 is relatively large, and the adsorption force between adjacent nozzles 4 is relatively small, so that the adhesive film 5 is in a wavy shape during the adsorption process. When the wavy adhesive film 5 is laid on the substrate, it is easy for the adhesive film 5 to have a bulging problem.

[0042] As Figures 2 - 5 shown, in order to solve the problem that the prior adsorption device easily causes the adhesive film 5 to bulge during the laying process, the adsorption plate 1 of the present application includes a body 11. The body 11 is divided into at least two regions along a first direction, and each region is provided with a plurality of adsorption channels 111 and exhaust channels 112 communicating with the plurality of adsorption channels 111. The adsorption channels 111 in each region are all arranged on the first side of the body 11 along a second direction.

[0043] By arranging a plurality of adsorption channels 111 on the first side of each region along the second direction, the adsorption force of the adsorption plate 1 can be made more balanced, the problem that the adhesive film 5 is deformed due to uneven adsorption force can be avoided, and the flatness of the adhesive film 5 during the adsorption process is improved. In addition, by dividing the adsorption plate 1 into at least two regions, each region is provided with a dedicated adsorption channel 111 and an air extraction channel 112 communicated therewith, so that the suction force of each region can be independently adjusted, and thus the adsorption force of each region can be controlled in a partitioned manner according to the characteristics of the adhesive film 5, greatly ensuring the flatness of the adhesive film 5 during the laying process and avoiding the problem of the adhesive film 5 bulging.

[0044] Next, further refer to Figures 2 - 5 A preferred embodiment of the adsorption plate 1 of the present application will be introduced. Those skilled in the art can understand that the following introduced embodiments are only used to illustrate the principle of the present application and are not intended to limit the protection scope of the present application. On the premise that the adsorption plate 1 at least includes the main body 11, those skilled in the art can adjust the following setting methods so that the present application can be applied to more specific application scenarios.

[0045] See Figures 2 - 5 , the adsorption plate 1 includes a main body 11 and a silica gel plate 12. The main body 11 is sequentially divided into three regions along the first direction (such as the X direction shown in Figure 2 ), namely the first region 114, the second region 115 and the third region 116. Three adsorption channel groups are provided on the first side of the first region 114 and the third region 116 along the second direction (such as the Z direction shown in Figure 2 ), and five adsorption channel groups are provided on the first side of the second region 115 along the second direction. The 11 adsorption channel groups on the main body 11 are arranged at equal intervals along the first direction. Each adsorption channel group includes a plurality of adsorption channels 111, and the plurality of adsorption channels 111 are arranged at equal intervals along the third direction (such as the Y direction shown in Figure 2 ). Through the above setting method, the adsorption plate 1 can generate a uniform adsorption force, thereby improving the flatness of the adhesive film 5 during the adsorption process.

[0046] Of course, the number of regions set in the present application and the number of adsorption channel groups set in each region are not fixed, and those skilled in the art can adjust according to the setting needs. For example, the number of regions set can be 2, 4, 5 or other numbers. And / or, the number of adsorption channel groups in each region can be the same, such as 2, 3, 4 or other numbers; or different, for example, the number of adsorption channel groups in the first region 114 is 3, the number of adsorption channel groups in the second region 115 is 4, and the number of adsorption channel groups in the third region 116 is 5.

[0047] Then see Figures 2 - 3 andFigure 5 On the first side of the first region 114 and the third region 116 in the third direction, three air extraction channels 112 corresponding one-to-one to the adsorption channel groups are provided. On the first side of the second region 115 in the third direction, five air extraction channels 112 corresponding one-to-one to the adsorption channel groups are provided. Each air extraction channel 112 extends along the third direction and communicates with a plurality of adsorption channels 111 in the corresponding adsorption channel group, so that the adsorption channels 111 can generate an adsorption force under the action of the air extraction channels 112, and each adsorption channel group is independent of each other, so that the adsorption force of each region can be controlled separately.

[0048] Of course, the opening positions of the air extraction channels 112 in each region of the present application are not fixed, and those skilled in the art can adjust them according to the setting requirements. For example, a part of the three adsorption channel groups in the first region 114 can be opened on the first side of the first region 114 in the third direction, and the remaining adsorption channels can be opened on the second side of the first region 114 in the third direction. And / or, a part of the five adsorption channel groups in the second region 115 can be opened on the first side of the second region 115 in the third direction, and the remaining adsorption channels can be opened on the second side of the second region 115 in the third direction. And / or, a part of the three adsorption channel groups in the third region 116 can be opened on the first side of the first region 114 in the third direction, and the remaining adsorption channels can be opened on the second side of the third region 116 in the third direction.

[0049] Next, refer to Figure 2 On the second side of the main body 11 in the second direction, a plurality of weight reduction grooves 113 are provided, so as to reduce the weight of the adsorption plate 1. On the first side of the main body 11 in the second direction, a silica gel plate 12 is provided. A plurality of through holes communicating with the adsorption channels 111 are provided on the silica gel plate 12, so that the through holes can generate an adsorption force under the action of the adsorption channels 111 and the air extraction channels 112.

[0050] Of course, the opening positions of the weight reduction grooves 113 in the present application are not fixed, and those skilled in the art can adjust them as needed. For example, a plurality of weight reduction grooves 113 can also be opened on the main body 11 in the first direction, and / or a plurality of weight reduction grooves 113 can also be opened on one or both sides of the main body 11 along the third direction. In addition, the present application can also open a plurality of weight reduction holes on the second side of the main body 11 in the second direction, and the weight reduction holes can also play a role in reducing the weight of the adsorption plate 1.

[0051] It should be noted that in other preferred embodiments, the setting of the silica gel plate 12 in the present application is not necessary, and those skilled in the art can choose according to the needs.

[0052] In addition, the present application also provides an adsorption device, which includes an air extraction mechanism and the adsorption plate 1 of any of the above embodiments; the air extraction holes 112 in each area are respectively connected to the air extraction mechanism.

[0053] By adopting the air extraction mechanism in the present application, the adsorption plate 1 can generate an adsorption force. Moreover, arranging a plurality of adsorption holes 111 on the first side along the second direction in each area can prevent the adhesive film 5 from deforming due to uneven adsorption force, and improve the flatness of the adhesive film 5 during the adsorption process. In addition, the air extraction mechanism is respectively communicated with the air extraction holes 112 in each area, so that the suction force in each area can be independently adjusted. Thus, the adsorption force of each area can be controlled in a zoned manner according to the characteristics of the adhesive film 5, which greatly ensures the flatness of the adhesive film 5 during the laying process and avoids the problem of the adhesive film 5 bulging.

[0054] Combined with Figures 2 - 3 , the adsorption device further includes three switching elements (not shown in the figure). The three switching elements are all solenoid valves. The three solenoid valves are the first solenoid valve, the second solenoid valve and the third solenoid valve respectively. The three solenoid valves correspond to the three areas one by one and are all connected to a centrifugal fan (not shown in the figure). That is, the three air extraction holes 112 in the first area 114 are all connected to the centrifugal fan through the first solenoid valve, the five air extraction holes 112 in the second area 115 are all connected to the centrifugal fan through the second solenoid valve, and the three air extraction holes 112 in the third area 116 are all connected to the centrifugal fan through the third solenoid valve. In the above setting method, the centrifugal fan can play a role in air extraction, so that the adsorption holes 111 can generate an adsorption force under the action of the centrifugal fan connected to the air extraction holes 112. The air extraction holes 112 in each area are connected to the centrifugal fan through the corresponding solenoid valve, so that the adsorption plate 1 can achieve zoned control.

[0055] Certainly, the specific setting form of the air extraction mechanism in the present application is not fixed, and those skilled in the art can adjust it according to the setting requirements. For example, the air extraction mechanism can also be a vacuum extraction device.

[0056] It should be noted that the number of switching elements set is the same as the number of areas corresponding. For example, when the number of areas is 4, the number of switching elements is also 4, so as to facilitate the separate control of the adsorption force of each area.

[0057] Certainly, the setting form or the number of switching elements in the present application is not fixed, and those skilled in the art can adjust it according to the setting requirements. For example, the switching element can also be an electric valve. And / or, a solenoid valve can be configured for each air extraction hole 112, so as to control the adsorption force of the adsorption hole 111 corresponding to each air extraction hole 112.

[0058] Then combined with Figures 2 - 4, the adsorption device also includes a connecting mechanism 2 and an elastic mechanism 3, the elastic mechanism 3 is arranged on the side of the adsorption plate 1 away from the adsorption channel 111, that is, the elastic mechanism 3 is arranged on the second side of the adsorption plate 1 in the second direction. Among them, the connecting mechanism 2 includes a connecting frame 21 and a connecting plate 22, the connecting plate 22 is located on the second side of the second direction of the adsorption plate 1, and the connecting frame 21 is arranged in the middle position of the side of the connecting plate 22 away from the adsorption plate 1. The side of the connecting frame 21 away from the adsorption plate 1 can be connected to the moving mechanism, so that the adsorption plate 1 can also move with the moving mechanism while driving the connecting mechanism 2 to translate or lift. The four corners of the connecting plate 22 are respectively provided with mounting holes. The number of elastic mechanisms 3 is 4, and each elastic mechanism 3 includes a limit block 33, a guide rod 31, a spring 32, a sleeve 34 and a fixed seat 35. The sleeve 34 is arranged on the side of the connecting plate 22 away from the adsorption plate 1, and corresponds to and is connected with the mounting hole. The guide rod 31 is inserted into the mounting hole so that the connecting plate 22 can move in the second direction along the guide rod 31. One end of the guide rod 31 passes through the sleeve 34 and is connected to the stop block 33 outside the sleeve 34. The maximum outer diameter of the stop block 33 is greater than the inner diameter of the sleeve 34, so as to prevent the connecting plate 22 from coming off the guide rod 31 during the movement along the guide rod 31. The other end of the guide rod 31 passes through the mounting hole and is connected to the fixing seat 35. The fixing seat 35 is connected to the body 11 on the side away from the guide rod 31, so that when the moving mechanism drives the connecting mechanism 2 to move, the adsorption plate 1 can move accordingly under the action of the elastic mechanism 3. The spring 32 is sleeved on the guide rod 31 between the connecting mechanism 2 and the adsorption plate 1, so that when the adsorption device lays the adhesive film 5 on the adsorption plate 1 on the substrate, the adsorption plate 1 can achieve a flexible downward pressing action under the elastic force provided by the spring 32, ensuring that the adhesive film 5 can be more smoothly and evenly attached to the substrate.

[0059] It should be noted that there is no restriction on the setting position of the limit block 33, as long as it can prevent the guide rod 31 from escaping from the sleeve 34. For example, a limit block 33 can be set at the end of the guide rod 31 away from the adsorption plate 1, or a limit block 33 can also be set on the outer wall of the part of the guide rod 31 extending out of the sleeve 34. In addition, in other preferred embodiments, the present application does not necessarily require the provision of the sleeve 34 and / or the fixing seat 35, and those skilled in the art can choose according to the setting needs. In the case where the sleeve 34 is not provided, one end of the guide rod 31 passes through the mounting hole and a limit block 33 is provided. The maximum outer diameter of the limit block 33 is larger than the mounting hole, thereby preventing the guide rod 31 from escaping from the mounting hole. In the case where the fixing seat 35 is not provided, the end of the guide rod 31 extending out of the mounting hole can be directly connected to the body 11.

[0060] Of course, the number and form of the elastic mechanism 3 provided in this application are not fixed, and those skilled in the art can adjust them according to specific application scenarios. For example, the number of the elastic mechanisms 3 can be 1, 2 or other numbers. And / or, the elastic mechanism 3 can also be an elastic block, and the elastic block can be sleeved on the guide rod 31. When the number of the elastic mechanisms 3 is 1, the elastic mechanism 3 can be arranged at the middle position of the connecting plate 22. At this time, the connecting mechanism 2 can be arranged at other positions of the connecting plate 22 to prevent the elastic mechanism 3 from conflicting with the connecting mechanism 2.

[0061] Combined with Figures 2 - 5 , the method of laying the adhesive film 5 by the adsorption device of this application will be described:

[0062] The adsorption device moves to the position of the adhesive film 5 driven by the moving mechanism, and the silica gel plate 12 on the adsorption plate 1 contacts the adhesive film 5. At this time, the air extraction mechanism can be started and the opening degrees of the three solenoid valves can be controlled to ensure the balance of the adsorption force on the silica gel plate 12, so that the adhesive film 5 can be adsorbed on the adsorption plate 1, and the flatness of the adhesive film 5 can also be ensured. Subsequently, the adsorption device adsorbed with the adhesive film 5 is driven to move to the position of the substrate, and the adhesive film 5 on the silica gel plate 12 contacts the substrate. Then, by controlling the operation of the second solenoid valve, the adsorption force in the second region 115 is reduced, so that the adsorption force of the silica gel plate 12 in this region on the adhesive film 5 gradually weakens until the adhesive film 5 in this region falls off and is preferentially laid on the substrate. Immediately afterwards, the first and third solenoid valves are synchronously controlled so that the adsorption forces of the silica gel plates 12 in the first region 114 and the third region 116 on the adhesive film 5 also gradually decrease until the adhesive film 5 can smoothly detach from the adsorption plate 1 and be laid on the substrate, completing the entire process of laying the adhesive film 5 and improving the flatness of the laid adhesive film 5.

[0063] It should be noted that when the number of regions on the main body 11 is two, the adsorption force of the two regions can be reduced simultaneously until the adhesive films 5 of the two regions are detached from the adsorption plate 1 and laid on the substrate, thereby ensuring the flatness of the laying of the adhesive film 5. When the number of regions on the main body 11 exceeds three, the adsorption force can be gradually reduced from the middle to both sides to ensure the flatness of the laying of the adhesive film 5. For example, when the number of regions is odd, taking 5 regions as an example for illustration. At this time, the main body 11 is sequentially divided into the first, second, third, fourth, and fifth regions along the first direction. When laying the adhesive film, the adsorption force of the third region can be first controlled to gradually decrease until the adhesive film 5 of the third region is detached from the adsorption plate 1 and laid on the substrate. Then, the adsorption forces of the second and fourth regions are controlled to gradually decrease until the adhesive films 5 of the second and fourth regions are detached from the adsorption plate 1 and laid on the substrate. Finally, the adsorption forces of the first and fifth regions are controlled to gradually decrease until the adhesive films 5 of the first and fifth regions are detached from the adsorption plate 1 and laid on the substrate. For example, when the number of regions is even, taking 6 regions as an example for illustration. At this time, the main body is sequentially divided into the first, second, third, fourth, fifth, and sixth regions along the first direction. When laying the adhesive film, the adsorption forces of the third and fourth regions can be first controlled to gradually decrease until the adhesive films 5 of the third and fourth regions are detached from the adsorption plate 1 and laid on the substrate. Then, the adsorption forces of the second and fifth regions are controlled to gradually decrease until the adhesive films 5 of the second and fifth regions are detached from the adsorption plate 1 and laid on the substrate. Finally, the adsorption forces of the first and sixth regions are controlled to gradually decrease until the adhesive films 5 of the first and sixth regions are detached from the adsorption plate 1 and laid on the substrate.
