[0040] See Figures 1 to 4 An embodiment of the present invention provides a laminate repair device, which includes a substrate 100, a fixing plate 200 and an adjustment component 300. The substrate 100 is divided into a plurality of positioning areas 110 arranged at intervals; a fixing plate 200 is provided at each of the opposite ends of the substrate 100, and the fixing plate 200 is arranged at an angle to the substrate 100; an adjustment component 300 is provided on each fixing plate 200, and the distance between the opposite ends of the two adjustment components 300 is adjustable; wherein, the space enclosed by the substrate 100 and the two fixing plates 200 is used to accommodate a photovoltaic cell string 700, one positioning area 110 corresponds to one photovoltaic cell, and the two ends of the photovoltaic cell string 700 are abutted against the end of the corresponding adjustment component 300.

[0041] The present technical solution provides a stacking repair device, wherein a substrate 100 is used to support a cell string 700 that needs repair. A plurality of spaced positioning areas 110 are provided on the substrate 100 to facilitate placement and positioning of the corresponding photovoltaic cells in the cell string 700. Fixing plates 200 are provided at opposite ends of the substrate 100, and the fixing plates 200 are arranged at an angle to the substrate 100, so that the adjustment assembly 300 can be installed while preliminarily determining the positioning area 110 of the cell string 700. The distance between the opposite ends of the adjustment assembly 300 provided at both ends of the substrate 100 is set to an adjustable form, so that the stacking repair device provided by the present invention can position the cell strings 700 of different models by adjusting the distance between the opposite ends of the two adjustment assemblies 300. Through the above structure, the entire stacking repair device can be applied to photovoltaic cell strings 700 of different sizes, thereby improving repair efficiency and reducing production costs.

[0042] like Figure 4As shown, it can be understood that when the laminate repair device provided in this embodiment is in use, the front glass 500 and the adhesive layer 600 are located below the substrate 100. Specifically, the velvet surface of the front glass 500 faces the substrate 100, and the adhesive layer 600 is an EVA adhesive layer. The adhesive layer 600 is bonded to the velvet surface of the front glass 500, with the other adhesive surface facing the substrate 100. The photovoltaic cell string 700 is located above the substrate 100. After the laminate repair device aligns the photovoltaic cell string 700, the adhesive layer, and the front glass 500, the laminate repair device is withdrawn, and the photovoltaic cell string 700 can fall on the adhesive layer, thereby achieving the positioning of the photovoltaic cell string 700 and the front glass 500.

[0043] like Figure 2 As shown, in this embodiment, the substrate 100 is a rectangular plate made of acrylic to reduce the weight of the entire laminate repair apparatus. Multiple positioning areas 110 are spaced apart along the length of the substrate 100, each corresponding to a photovoltaic cell. This allows each cell in the cell string 700 to be placed in a corresponding positioning area 110 during repair of the laminate structure. Furthermore, the fixing plate 200 is perpendicular to the substrate 100.

[0044] like Figures 1 to 3 As shown, in one embodiment, the adjustment assembly 300 includes an adjustment rod 310, a connecting rod 320 and a baffle 330, wherein the adjustment rod 310 is movably connected to the fixed plate 200; one end of the connecting rod 320 is fixedly connected to the adjustment rod 310; the baffle 330 is connected to the other end of the connecting rod 320, and the top of the baffle 330 protrudes from the top surface of the substrate 100, and the baffle 330 is used to support the end of the photovoltaic cell string 700; wherein, the fixed plate 200 and the substrate 100 are provided with an avoidance groove for the connecting rod 320 to move and extend. By movably connecting the adjustment rod 310 to the fixed plate 200, and by fixedly connecting the ends of the connecting rod 320 to the adjustment rod 310 and the baffle 330, respectively, the adjustment rod 310 can be moved to allow the connecting rod 320 and the baffle 330 to move relative to the fixed plate 200. This allows the distance between the two baffles 330 disposed at both ends of the base plate 100 to be adjusted according to the size of the battery string 700, thereby achieving positioning of different types of battery strings 700. For example, when the size of the battery string 700 is large, the distance between the two baffles 330 is increased; when the size of the battery string 700 is small, the distance between the two baffles 330 is decreased.

[0045] like Figure 3As shown, specifically, an avoidance groove for the movement of the baffle 330 is provided on the fixed plate 200 and the base plate 100, the adjusting rod 310 is movably connected to the fixed plate 200, and the top end of the baffle 330 is exposed from the avoidance groove to the top surface of the base plate 100, thereby facilitating the positioning of the battery string 700 placed on the base plate 100, and the connecting rod 320 is arranged in the avoidance groove and can move in the avoidance groove.

[0046] like Figure 1 As shown, in one embodiment, the adjustment assembly 300 further includes a locking member 340, which is movably connected to the fixed plate 200, and the locking member 340 can move toward or away from the adjustment rod 310; wherein, when the locking member 340 moves toward the adjustment rod 310 until it presses against the adjustment rod 310, the adjustment rod 310 is locked relative to the fixed plate 200.

[0047] By movably connecting the locking member 340 to the fixed plate 200, when the distance between the two baffles 330 needs to be adjusted, the locking member 340 is moved away from the adjustment rod 310 so that the adjustment member can move relative to the fixed plate 200, thereby facilitating adjustment of the distance between the two baffles 330. When the distance between the two baffles 330 is adjusted to the target position, the locking member 340 is moved toward the adjustment rod 310 so that the locking member 340 presses against the adjustment rod 310, thereby limiting the adjustment rod 310 and locking the distance between the two baffles 330, thereby improving the reliability of positioning the battery string 700.

[0048] Specifically, the adjustment rod 310 is constructed as a flat square structure; a guide groove compatible with the adjustment rod 310 is provided on the fixed plate 200, and the adjustment rod 310 is inserted into the guide groove; the locking member 340 can extend into the guide groove and abut against the adjustment rod 310. By configuring the adjustment rod 310 as a flat square structure, providing a guide groove on the fixed plate 200, and configuring the guide groove to be compatible with the structure of the adjustment rod 310, the movement of the adjustment rod 310 is guided by the guide groove. The locking member 340 is configured to be able to extend into the guide groove so that the locking member 340 can press against the guide rod, thereby clamping the adjustment rod 310 simultaneously through the locking member 340 and the side wall of the guide groove, thereby limiting the movement of the adjustment rod 310 relative to the fixed plate 200. Specifically, the locking member 340 is threadedly engaged with the fixed plate 200. The locking piece 340 is matched with the fixing plate 200 through threads. On the one hand, the structure is simple and easy to adjust; on the other hand, the warning force of the threads can apply a clamping force to the locking piece 340, thereby preventing the adjustment rod 310 from moving relative to the fixing plate 200.

[0049] like Figure 2As shown, in one embodiment, a scale is provided on the baffle 330, and the setting direction of the scale is along the moving direction of the adjusting rod 310. A positive or negative pole mark is provided on the substrate 100 corresponding to each positioning area 110. By providing a scale on the baffle 330, the operator can directly read the scale on the baffle 330 when adjusting the distance between the baffles 330. Such a setting makes the adjustment of the baffle 330 simpler and more operable. By providing a positive or negative pole mark on the substrate 100 corresponding to each positioning area 110, when positioning the battery string 700, the positive and negative poles of the battery cells on the battery string 700 can be matched through the positive and negative pole marks of the positioning area 110, thereby ensuring the reliability of positioning.

[0050] like Figure 2 As shown, in one embodiment, a limiting groove 120 is provided between two adjacent positioning areas 110 on the substrate 100, and a limiting plate 400 is provided in the limiting groove 120. The limiting plate 400 protrudes from the substrate 100, and the position of the limiting plate 400 in the limiting groove 120 is adjustable. Specifically, the extension direction of the limiting groove 120 is along the length direction of the substrate 100, and the length of the limiting groove 120 is set slightly longer, so that the position of the limiting plate 400 in the limiting groove 120 can be adjusted according to the model of different battery strings 700, thereby positioning the battery cells in the battery string 700 of the corresponding model. In this embodiment, the limiting plate 400 is set to protrude from the substrate 100, so that the battery cells in the battery string 700 are limited by the limiting plate 400. Specifically, the height of the limiting plate 400 protruding from the substrate 100 is approximately 2 mm. Furthermore, scale lines are provided on the edges of the groove walls of the limiting grooves 120 to facilitate identification of the tolerance range of the battery cells.

[0051] like Figure 2 As shown, in one embodiment, a positioning groove 130 is provided on one side of the substrate 100, and the positioning groove 130 extends along the length direction of the substrate 100. By providing the positioning groove 130 on the substrate 100, it is convenient to locate the welding position of the battery cell. The conductive sheet is inserted into the positioning groove 130 and connected to the terminal to achieve welding positioning. This arrangement makes the connection operation between the busbar template and the battery cell welding ribbon more convenient. The busbar can be pre-fixed in the positioning groove 130 for easy observation. After welding, the conductive sheet is pressed and fixed by a pressing plate, which can increase the tin protection effect of the conductive sheet and increase the product warranty service life.

[0052] like Figure 2As shown, in one embodiment, a plurality of handles 140 are provided at intervals on one side of the substrate 100. Specifically, the handles 140 are installed at the lead-out terminals of the substrate 100 to facilitate the removal and placement of the laminate rework device. In this embodiment, a positioning hole for adjusting the creepage dimension is installed on one side of the substrate 100 where the handles 140 are located. The measuring range dimensions are marked on the hole, and a measuring range stop 330 is installed on the positioning hole to facilitate adjustment and positioning of the creepage range.

[0053] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0054] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
