[0001] The invention relates to the technical field of photovoltaic panel production, and in particular to a photovoltaic component lamination device. Background Art

[0002] In the production process of photovoltaic modules, the lamination process is a crucial link, which is directly related to the molding quality, flatness and internal gas removal of photovoltaic modules. Traditional photovoltaic module lamination devices mostly use static pressing, that is, the pressing plate directly presses down to press the photovoltaic module. However, this method often has problems such as uneven pressing, insufficient flatness and difficulty in completely removing internal gas, which affects the performance and service life of photovoltaic modules. Summary of the invention

[0003] The purpose of the present invention is to provide a photovoltaic module laminating device, which improves the lamination quality and flatness by rolling a pressing roller on the photovoltaic module during the pressing process of a pressing plate.

[0004] The present invention adopts the following technical solution: a photovoltaic module laminating device, comprising a lifting mechanism and a laminating board assembly fixedly connected under the lifting mechanism; Also includes: A left swing assembly, wherein the upper end of the left swing assembly is hinged to the left of the upper part of the laminate assembly, and the lower end of the left swing assembly is tilted to the right; A left elastic member connected between the left swing assembly and the laminate assembly, the left elastic member providing a pulling force to rotate the lower end of the left swing assembly to the left; A right pressure roller, hinged to the lower end of the left swing assembly; The right swing assembly is symmetrical in structure with the left swing assembly; the upper end of the right swing assembly is hinged to the right above the laminate assembly, the lower end of the right swing assembly is inclined to the left, and the lower end of the right swing assembly crosses the lower end of the left swing assembly; A right elastic member connected between the right swing assembly and the laminate assembly, the right elastic member providing a pulling force to rotate the lower end of the right swing assembly to the right; The left pressure roller is hinged at the lower end of the right swing assembly and abuts against the right pressure roller.

[0005] Further, the left swing assembly comprises two symmetrical left support rods disposed on both sides of the laminate assembly, the upper ends of the two left support rods are fixedly connected with a left rotating shaft, and the left rotating shaft is rotatably mounted on the laminate assembly; The two ends of the right pressure roller are rotatably mounted on the lower ends of the two left support rods respectively; The right swing assembly includes two symmetrical right support rods disposed on both sides of the laminate assembly, the upper ends of the two right support rods are fixedly connected with a right rotating shaft, and the right rotating shaft is rotatably mounted on the laminate assembly; The two ends of the left pressure roller are rotatably mounted on the lower ends of the two right support rods respectively.

[0006] A left elastic scraper is fixed to the lower ends of the two left support rods, and one side of the left elastic scraper is attached to the right pressure roller; A right elastic scraper is fixed to the lower ends of the two right support rods, and one side of the right elastic scraper is attached to the left pressure roller.

[0007] A one-way linkage is fixed on the laminate assembly, and the one-way linkage is used to unidirectionally control the left and right rotating shafts to rotate in opposite directions at the same speed.

[0008] The one-way linkage comprises: a motor fixed on the laminate assembly; A one-way ratchet, sleeved and fixed on the output shaft of the motor; The first driving sprocket and the second driving sprocket are respectively fixed on the one-way ratchet; A left sprocket, which is fixed on the left rotating shaft and connected to the first driving sprocket through a chain; The right sprocket is fixedly mounted on the right rotating shaft and connected with the second driving sprocket through another chain.

[0009] The laminate assembly comprises: A pressing plate, a heating weight assembly being fixed on the upper side of the pressing plate; Four legs are arranged in a rectangular shape and fixed on the upper side of the pressing plate; the two legs on the left are hinged to the upper end of the left swing assembly, and the two legs on the right are hinged to the upper end of the right swing assembly; A top plate is fixed on the upper ends of the four legs.

[0010] The top plate is in an inverted U shape, and is attached to the top and side surfaces of the supporting legs and fixed together by welding.

[0011] The lifting mechanism comprises a vertically arranged cylinder, and the piston rod end of the cylinder is fixed to the top plate through a flange.

[0012] The beneficial effects of the present invention are: When the pressing plate moves downward and presses the photovoltaic modules, the left swing module and the right swing module are rolled from the middle of the photovoltaic modules to the two sides by the pressing rollers, thereby improving the flatness of the photovoltaic modules before pressing. The rolling of the pressing rollers also helps to reduce the gas inside the photovoltaic modules and ensure the molding quality of the photovoltaic modules. The one-way linkage is used to achieve the same-speed and opposite-direction swinging of the left and right support rods, thereby ensuring that the left and right pressure rollers can move in opposite directions and at the same speed, thereby improving the stability of the pressure rollers moving on the photovoltaic module. In addition, the one-way ratchet also prevents the pressure rollers from swinging back in the opposite direction when moving outside the photovoltaic module, thereby avoiding the problem that the pressure rollers may touch the pressed photovoltaic module when they swing back after the pressing is completed.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1: like Figure 1 As shown, the present invention provides a photovoltaic module lamination device, which mainly includes a lifting mechanism 1, a laminate assembly 2, a left swing assembly 3 and a right swing assembly 6.

[0023] Combination Figures 1 to 3 As shown, the laminate assembly 2 includes a rectangular pressing plate 21. When working, the pressing plate 21 is pressed on the photovoltaic assembly so that the photovoltaic assembly can be pressed together better. A heating counterweight assembly 24 is fixed on the upper side of the pressing plate 21. The heating counterweight assembly 24 is in a square shape and has a heating device inside to provide heat for the pressing plate 21. In this embodiment, the pressure of the pressing plate 21 is mainly provided by the heating counterweight assembly 24. The weight distribution of the heating counterweight assembly 24 itself is relatively uniform, which can improve the pressing quality of the photovoltaic assembly. The four legs 22 are distributed in a rectangular shape and are fixed to the pressing plate 21 by bolts. The inverted U-shaped top plate 23 is buckled on the upper ends of the four legs 22. The top plate 23 is attached to the top and side of the legs 22 and is fixed as a whole by welding.

[0024] The lifting mechanism 1 includes a cylinder 11, and the piston rod of the cylinder 11 is arranged vertically downward. The piston rod end of the cylinder 11 is fixed to the top plate 23 through a flange 12. In this embodiment, the cylinder 11 is mainly used to control the lifting of the laminate assembly 2, and does not provide downward pressure for the laminate assembly 2, so as to avoid the pressure plate 21 generating high pressure at the four legs 22, resulting in uneven pressure on the photovoltaic module.

[0025] Combination Figures 1 to 4 As shown, the left swing assembly 3 and the right swing assembly 6 are installed on the laminate assembly 2. The left swing assembly 3 and the right swing assembly 6 are symmetrical in structure. This embodiment is mainly described with reference to the left swing assembly 3: The left swing assembly 3 includes two symmetrical left support rods 31, and the two left support rods 31 are disposed on both sides of the pressure plate 21. The two ends of the left rotation shaft 32 are respectively fixedly connected to the upper ends of the two left support rods 31, and the left rotation shaft 32 is passed through the two legs 22 on the left side and is rotatably connected to the two legs 22. The upper and lower ends of the two left support rods 31 are respectively connected to a reinforcing rib plate to improve the overall rigidity of the left swing assembly 3. The position of the reinforcing rib plate should avoid interference with other components when rotating with the left support rod 31. Initially, the lower end of the left support rod 31 is tilted to the right; the two ends of the right pressure roller 4 are rotatably mounted on the lower ends of the two left support rods 31.

[0026] Similarly, the right swing assembly 6 includes a right shaft 62 and two symmetrical right support rods 61, and the right shaft 62 is rotatably mounted on the two right support legs 22. Initially, the lower end of the right support rod 61 tilts to the left and passes over the lower end of the left support rod 31, so that the lower ends of the right support rod 61 and the left support rod 31 intersect; the two ends of the left pressure roller 8 are rotatably mounted on the lower ends of the two right support rods 61, and abut against the right pressure roller 4, so that the lower ends of the right support rod 61 and the left support rod 31 cannot be reversely separated.

[0027] A pair of left elastic members 5 are respectively hinged between the left support rod 31 and the left support leg 22, and the left elastic member 5 provides a pulling force for the left support rod 31 to rotate to the left. A pair of right elastic members 7 are respectively hinged between the right support rod 61 and the right support leg 22, and the right elastic member 7 provides a pulling force for the right support rod 61 to rotate to the right. The left elastic member 5 and the right elastic member 7 can use gas spring rods to facilitate adjusting the pulling force.

[0028] When working, Combination Figure 1 and Figure 6 As shown, the photovoltaic module is placed on the workbench, and the lifting mechanism 1 drives the laminate module 2 to descend; after the right pressure roller 4 and the left pressure roller 8 contact the photovoltaic module, they begin to roll to the two sides of the photovoltaic module; the left support rod 31 and the right support rod 61 gradually rotate, and the left elastic member 5 and the right elastic member 7 provide a certain pulling force for the left support rod 31 and the right support rod 61, so that the right pressure roller 4 and the left pressure roller 8 roll from the middle of the photovoltaic module to the two sides under a certain pressure until the right pressure roller 4 and the left pressure roller 8 roll out of the photovoltaic module, and the pressure plate 21 is pressed onto the photovoltaic module, thereby improving the flatness of the photovoltaic module before pressing, reducing the gas inside the photovoltaic module, and ensuring the molding quality of the photovoltaic module.

[0029] Embodiment 2: Based on the above embodiment 1, Figures 1 to 5 As shown, a one-way linkage 9 is connected between the left rotating shaft 32 and the right rotating shaft 62; The one-way linkage 9 includes a motor 91 fixed to the lower side of the top plate 23. A one-way ratchet 92 is fixedly mounted on the output shaft of the motor 91. The one-way ratchet 92 can only rotate in one direction relative to the output shaft of the motor 91. A first driving sprocket 93 and a second driving sprocket 94 are fixedly mounted on the one-way ratchet 92. A left sprocket 95 is fixedly mounted on the left rotating shaft 32. The left sprocket 95 is connected to the first driving sprocket 93 through a chain 97. A right sprocket 96 is fixedly mounted on the right rotating shaft 62. The right sprocket 96 is connected to the second driving sprocket 94 through another chain 97.

[0030] Combined with the working process in Example 1; Combination Figure 1 and Figure 6 As shown, when the lifting mechanism 1 drives the laminate assembly 2 to descend, the motor 9 is in a self-locking state; When the left support rod 31 and the right support rod 61 swing, the corresponding left rotating shaft 32 and right rotating shaft 62 thereon start to rotate; since the left rotating shaft 32 and the right rotating shaft 62 are finally connected to the one-way ratchet 92 through the sprocket and the chain, under the linkage action of the one-way ratchet 92, the left rotating shaft 32 and the right rotating shaft 62 rotate at the same speed and in opposite directions; thereby, the left support rod 31 and the right support rod 61 swing at the same speed and in opposite directions, thereby ensuring that the right pressure roller 4 and the left pressure roller 8 can move in opposite directions at the same speed, thereby improving the stability of the right pressure roller 4 and the left pressure roller 8 in moving on the photovoltaic module.

[0031] In addition, if Figure 6 As shown, since the one-way ratchet 92 can only rotate in one direction, when the right pressure roller 4 and the left pressure roller 8 move outside the photovoltaic module, the one-way ratchet 92 makes Figure 6 The left support rod 31 and the right support rod 61 in the pressing operation cannot swing back in the opposite direction; therefore, when the pressing is completed and the lifting mechanism 1 drives the laminate assembly 2 to rise and reset, the left support rod 31 and the right support rod 61 can maintain a stable state, thereby preventing the left support rod 31 and the right support rod 61 from swinging back in the opposite direction and touching the pressed photovoltaic assembly; After the laminate assembly 2 is reset, the motor 91 is started, and the output shaft of the motor 91 slowly rotates (in the same direction as the allowable rotation direction of the one-way ratchet 92), and the left support rod 31 and the right support rod 61 are slowly reset to the position by the weight of the left support rod 31 and the right support rod 61 and the tension of the left elastic member 5 and the right elastic member 7. Figure 1 Position shown.

[0032] Embodiment three: Based on the above embodiment 1 or embodiment 2, Figures 1 to 4As shown, a left elastic scraper 33 is fixed to the reinforcing rib plate at the lower end of the left support rod 31, and the lower side of the left elastic scraper 33 is attached to the right pressure roller 4. Similarly, a right elastic scraper 63 is fixed to the reinforcing rib plate at the lower end of the right support rod 61, and the lower side of the right elastic scraper 63 is attached to the left pressure roller 8. By providing the left elastic scraper 33 and the right elastic scraper 63, the left pressure roller 8 and the right pressure roller 4 can be kept clean in this embodiment.

[0033] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
