Description

Technical Field

[0001] The present disclosure relates to the technical field of photovoltaic product processing, and in particular to a lamination tool and a lamination tool module. Background Art

[0002] Photovoltaic modules must be laminated at high temperatures in a laminator during the production process. Double-glass modules, in particular, are affected by the stress of the double glass during the lamination process, and are prone to defects such as bubbles, hidden cracks and broken pieces. When using ordinary laminating tooling, one module type must be adapted to one laminating tooling. There are currently no less than 10 types of module types on the market. If each type is equipped with a set of tooling, the manufacturing cost will be greatly increased during the module production process. At present, a laminator on a production line feeds at least 80 modules at the same time. In theory, a single line needs to be equipped with 100 sets of tooling, and 10 types of supporting tooling require about 1,000 sets, which results in a high production cost. Utility Model Content

[0027] As Figure 1 shown, a lamination tooling is applied to the lamination of photovoltaic modules, including: a frame 12, the frame 12 includes a second side and a first side that are fixedly connected, and the first side is a fixed side 11; and a movable side 13, and there are two movable sides 13; wherein, the two parallel movable sides 13 are perpendicular to the two fixed sides 11, and are slidably connected to the fixed sides 11 and can be locked.

[0028] The existing lamination tooling for photovoltaic modules has a fixed size, so a lamination tooling is required for each size of photovoltaic module. The lamination tooling in the present disclosure consists of a frame body and a movable side. The frame body has a fixed size. A slidable movable side 13 is provided on the first side of the frame body. The first side is a fixed side 11, and the movable side 13 has a fixed size. However, two parallel movable sides 13 can slide on the fixed side 11, and the effective length of the fixed side 11 can be adjusted. After the movable side slides to the target position, it can be locked in place, and the determined size is the size of the tooling required for laminating the photovoltaic module. The lamination tooling 1 in the present disclosure can be used for photovoltaic modules with the same width. In actual working conditions, the width dimensions of photovoltaic modules are several fixed ones, and the length requirements vary. In this case, the lamination tooling 1 in the present disclosure can meet most tooling requirements. When lamination toolings with different widths are needed, the lamination tooling 1 with the corresponding second side can be made according to the required width of the photovoltaic module. It should be noted that the movable side 13 and the fixed side 11 can achieve a sliding connection and the movable side 13 can be locked in place after moving to the target position. The lamination tooling 1 in the present disclosure has strong versatility and a relatively simple structure.

[0029] In some embodiments, the movable side 13 and the fixed side 11 have the same height in the vertical direction.

[0030] In order to better fit the photovoltaic module and perform lamination, in the new frame-shaped limiting structure formed by connecting the movable side 13 and the fixed side 11, the movable side 13 and the fixed side 11 are of the same height to facilitate better lamination of the photovoltaic module.

[0031] In some embodiments, the lamination tooling 1 further includes a corner pressing member 2, and the corner pressing member 2 is cooperatively connected to the two end portions of the movable side 13.

[0032] As Figure 2 In the shown embodiment, in order to protect the corners of the photovoltaic module and also to reduce the blistering rate of the photovoltaic module, a corner pressing member 2 is provided at the connection position of the fixed side 11 and the movable side 13 of the lamination tooling 1.

[0033] In some embodiments, the corner pressing member 2 includes a pressing member body 21, and the pressing member body 21 is an L-shaped structure.

[0034] The pressing member body 21 being an L-shaped structure can better cooperate with the corners of the photovoltaic module and also with the right angle at the connection position of the fixed side 11 and the movable side 13, making the corner pressing member 2 better fit the photovoltaic module. It should be noted that the pressing member body 21 with multiple thickness dimensions can be set to meet the requirements of photovoltaic modules with different thicknesses.

[0035] In some embodiments, the corner guard pressing member 2 further includes a buckle 22 disposed on the pressing member body 21. Grooves 131 are provided at both ends of the moving edge 13, and the structure of the buckle 22 is connected in cooperation with the structure of the grooves 131.

[0036] As Figure 2 In the illustrated embodiment, the corner guard pressing member 2 is further provided with a buckle 22. The structure of the buckle 22 is a protruding circular structure. The grooves 131 provided at both ends of the moving edge 13 are matched with the protruding structure of the buckle 22, so that the buckle 22 can be buckled with the grooves, thereby enabling the corner guard pressing member 2 to better reduce the amount of air bubbles generated at the four corners during the lamination of the photovoltaic module.

[0037] In some embodiments, after the corner guard pressing member 2 is connected to the moving edge 13, the height of the top of the corner guard pressing member 2 in the vertical direction is equal to the height of the top of the photovoltaic module in the vertical direction.

[0038] In order to further reduce the generation of air bubbles at the four corners during the lamination of the photovoltaic module, after the corner guard pressing member 2 is installed on the moving edge 13, the height of the corner guard pressing member 2 is consistent with the height of the photovoltaic module.

[0039] In some embodiments, a chute is provided on the fixed edge 11, and the moving edge 13 is provided with lockable rollers.

[0040] In an embodiment of the lockable sliding connection between the moving edge 13 and the fixed edge 11, the first embodiment is that a chute is formed on the fixed edge 11, rollers are provided at both ends of the moving edge 13 corresponding to the fixed edge 11, and a locking structure is provided on the rollers so that the moving edge 13 can be locked in position after moving to the target position in the chute.

[0041] In some embodiments, a guide rail 111 is provided on the fixed edge 11, and the moving edge 13 is provided with lockable sliders.

[0042] In an embodiment of the lockable sliding connection between the moving edge 13 and the fixed edge 11, the second embodiment is that a guide rail 111 is provided on the fixed edge 11, sliders matching the guide rail 111 are provided at both ends of the moving edge 13 corresponding to the fixed edge 11, and a locking structure is provided on the sliders so that the moving edge 13 can be locked in position after moving to the target position on the guide rail 111, as Figure 1 shown.

[0043] In some embodiments, the inner side wall of the fixed edge 11 is lower than the outer side wall.

[0044] After the fixed side 11 and the movable side 13 are slidably connected, in order to make the fixed side 11 and the movable side 13 have the same height, the inner and outer side walls of the fixed side 11 are set to different heights. Specifically, the inner side wall of the fixed side 11 is lower than the outer side wall. After the movable side 13 is connected to the fixed side 11, its height is ensured to be the same, so as to facilitate the subsequent installation of the corner guard pressing member 2 and the lamination process of the photovoltaic module.

[0045] When the lamination tooling 1 of the present disclosure is in use, the movable side 13 can be adjusted according to the peripheral size and thickness of the photovoltaic module to form a lamination frame with a new size. The two parallel movable sides 13 move within the frame formed by the first side and the second side. At the same time, L-shaped corner guard pressing members 2 with different thickness dimensions can be used to buckle on the four corners of the new lamination frame. After adjustment, the whole is sleeved on the photovoltaic module and enters the laminator for the lamination process. Using this lamination tooling 1 can avoid situations such as bubbles, hidden cracks and broken fragments during the lamination of the photovoltaic module, and ensure the product quality of the photovoltaic module after lamination. At the same time, this lamination tooling 1 can be used in multiple ways, is simple and easy to operate, reduces the production cost of the photovoltaic module, and improves the production efficiency.

[0046] The present disclosure also provides a lamination tooling module, which includes the above-mentioned lamination tooling 1.

[0047] In actual working conditions, there are mainly several widths of photovoltaic modules, and the lengths have many different sizes. In order to meet the lamination requirements of photovoltaic modules with different width sizes, the present disclosure also provides a lamination tooling module. On the basis of forming a lamination frame on the first side and the second side and setting a movable side 13 on the first side to make the length adjustable, the lamination tooling 1 with different second side sizes and movable sides 13 with sizes corresponding to the second side sizes is manufactured. In some embodiments, if there are 3 widths of photovoltaic modules in actual working conditions, three lamination toolings 1 with different sizes can be manufactured. The second side sizes of the three lamination toolings 1 are different, and three movable sides 13 with sizes corresponding to the second side sizes are respectively set on the lamination frames with three different second side sizes to meet the lamination of photovoltaic modules in most actual working conditions.

[0048] In practical applications of the lamination tooling 1, before lamination, the lamination tooling 1 of corresponding size needs to be completely sleeved on the photovoltaic module, and then enter the laminator together with the photovoltaic module for lamination. It should be noted that the photovoltaic module needs to be placed in the center of the lamination frame. When the temperature of the lamination process reaches about 140 °C, the EVA layer inside the photovoltaic module begins to melt. The lamination process is a process of combining vacuum pumping and pressurization. The main purpose is to use the melted EVA to bond the cells, glass, etc. inside the photovoltaic module into one body. Vacuum pumping can extract the air inside the photovoltaic module to prevent bubbles from generating inside the photovoltaic module. The lamination tooling 1 can prevent the air inside the photovoltaic module from being unable to be discharged after the periphery of the photovoltaic module is compacted. At the same time, the lamination tooling 1 can also prevent directly pressing on the photovoltaic module when the pressure of the laminator is too large, resulting in other defects.

In order to avoid obscuring the concept of the present disclosure, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed here based on the above description.
