Description

Technical Field

[0001] The utility model relates to the technical field of lamination equipment, in particular to a solar cell component lamination discharge and separation device. Background Art

[0002] Lamination is a core process in solar cell module production. The high temperature and high pressure of a laminator press together the various layers of a solar cell module to form a single unit. For example, a typical double-glass solar cell module consists, from top to bottom, of the panel glass, adhesive film, cells, adhesive film, and backsheet glass. After the pre-layout process, the laminator's conveyor mechanism transports the components to the lamination station. Under the laminator's high temperature, high pressure, and vacuum conditions, the adhesive film melts and solidifies, and the panel glass, cells, and backsheet are peeled and pressed together to form a complete module.

[0003] When the adhesive film melts, a small amount will overflow from the edge of the battery assembly and stick to and solidify on the upper and lower conveyor belts. When the battery assembly is lamination and separated, the end of the battery assembly corresponding to the laminator's discharge end will be slightly lifted up by the upper conveyor belt due to the overflow and stickiness of the adhesive film, and then separated and fallen, which may easily cause problems such as hidden cracks in the battery, position deviation of the battery string and poor contact.

[0004] The prior art is shown in the photovoltaic module and transmission cloth separation device and separation method proposed in patent application No. 202010895033.2. It identifies the position of the battery cell through a position sensor, and the corresponding pressure roller moves up and down to change the position and angle of the upper transmission cloth to separate it from the battery cell. The accuracy of the separation time and separation speed is affected by the circuit system such as the position sensor. The operation process is relatively complex and cumbersome, which is not conducive to energy-saving and efficient production. Utility Model Content

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A solar cell module lamination discharge separation device includes an idler roller and a pressure roller, wherein the idler roller and the pressure roller are respectively provided with a support belt and a downward pressure belt located below and above the solar cell module, the distance between the idler roller and the discharge end is smaller than the distance between the pressure roller and the discharge end, the interior of the support belt supports a stripping roller, the stripping roller is located between the idler roller and the pressure roller, and the bottom of the stripping roller and the bottom of the pressure roller are located in the same horizontal plane, the stripping roller is provided with a stripping blade on the outer side of the downward pressure belt corresponding to the stripping roller, and the stripping blade is tangent to the bottom belt surface of the downward pressure belt corresponding to the discharge end.

[0008] Preferably, the diameter of the peeling roller does not exceed 12 mm.

[0009] Preferably, there are multiple peeling rollers connected end to end in the same horizontal plane.

[0010] Preferably, the stripping roller is installed through a bearing frame, and the end of each stripping roller is installed with a bearing frame.

[0011] Preferably, the blade of the stripping blade is a concave smooth curved surface, and is adapted to the shape and size of the bottom belt surface on the side of the downward pressure belt corresponding to the discharge end.

[0012] Preferably, the stripping blade is L-shaped, and the portion below the stripping blade corresponding to the cutting edge remains horizontal.

[0013] Preferably, there are two stripping blades, which correspond to the positions of the front and rear edges of the battery assembly.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model arranges a stripping roller downstream of the pressure roller closest to the discharge end, and the bottom of the stripping roller is located at the same horizontal plane as the bottom of the pressure roller, and the diameter of the stripping roller is small, ensuring that the angle change rate of the pressing belt at the corresponding position is relatively large, so that it is not easy to pull the battery assembly upward when it is peeled from the battery assembly. In addition, a stripping blade for separating the battery assembly and the pressing belt is also provided at the position corresponding to the edge of the battery assembly, so that the separation of the two is smoother and avoids the problems of hidden cracks in the battery, position offset of the battery string and poor contact caused by the up and down vibration and impact of the end of the battery assembly. The utility model does not require a complex circuit control system, and can ensure smooth separation through a mechanical structure, thereby achieving the effect of energy saving and efficient production.

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, the utility model provides a technical solution: a solar cell module lamination discharge separation device, comprising an idler roller 1 and a pressure roller 2, the idler roller 1 and the pressure roller 2 are respectively provided with a support belt 4 and a downward pressure belt 5 located below and above the battery module 3, the distance between the idler roller 1 and the discharge end is smaller than the distance between the pressure roller 2 and the discharge end, the support belt 4 internally supports a stripping roller 6, the stripping roller 6 is located between the idler roller 1 and the pressure roller 2, and the bottom of the stripping roller 6 is located at the same horizontal plane as the bottom of the pressure roller 2;

[0024] The diameter of the peeling roller 6 does not exceed 12 mm. The diameter of the peeling roller 6 is relatively small, and the angle change rate of the pressing belt 5 at the corresponding position is large, which makes it easier for the pressing belt 5 to be separated from the battery assembly 3. There are multiple peeling rollers 6 and they are connected end to end in the same horizontal plane. The peeling rollers 6 are installed through bearing frames 8, and the ends of each peeling roller 6 are installed with bearing frames 8. Since the diameter of the peeling roller 6 is relatively small, if a whole long roller is used without support in the middle, it is easy for the roller to bend in the middle, resulting in poor support effect of the pressing belt 5 and looseness. The use of multiple bearing frames 8 to jointly install multiple peeling rollers 6 solves this problem very well.

[0025] A stripping blade 7 is provided on the outer side of the stripping roller 6 corresponding to the downward pressure belt 5. The stripping blade 7 is tangent to the bottom belt surface on the side corresponding to the discharge end of the downward pressure belt 5. The blade 71 of the stripping blade 7 is a concave and smooth curved surface, and is adapted to the shape and size of the bottom belt surface on the side corresponding to the discharge end of the downward pressure belt 5. The stripping blade 7 is L-shaped, and the part below the stripping blade 7 corresponding to the blade 71 remains horizontal. There are two stripping blades 7, and they correspond to the positions of the front and rear edges of the battery assembly 3.

[0026] Working principle:

[0027] The laminated battery assembly 3 is transported to the right discharge end through the joint action of the support roller 1, the pressure roller 2, the support belt 4 and the downward pressing belt 5. When the battery assembly 3 moves to the position corresponding to the peeling roller 6, the diameter of the peeling roller 6 is relatively small, so the angle change rate of the downward pressing belt 5 here is increased, which is conducive to its separation from the battery assembly 3 without driving the battery assembly 3 to move upward. At the same time, the peeling blade 7 corresponding to the front and rear edge positions of the battery assembly 3 can effectively separate the overflowed solidified film between the battery assembly 3 and the downward pressing belt 5. The peeling roller 6 and the peeling blade 7 work together, and the two cooperate with each other to make the battery assembly 3 and the downward pressing belt 5 separated smoothly, protecting the battery assembly 4 from damage and achieving energy-saving and efficient production.
