[0002] The solar cell module laminator draws a vacuum at high temperature to melt the module materials, expel the air and press them together. Figure 3 In the existing technology, the components are pressurized by using similar flexible materials such as silicone plates / rubber plates, and the components are pressurized by the vacuum pressure difference between the upper and lower chambers. For example: the component is located in the lower chamber, and the upper and lower chambers are separated by a silicone plate. When pressurized, the pressure in the lower chamber is 0KPa, and the pressure in the upper chamber is 80KPa. At this time, due to the pressure difference, the rubber plate is pressed on the component, forming a pressure of about 8t / ㎡. Ensure the flatness of the component and eliminate internal bubbles.

[0003] However, each time the lamination is performed, the rubber sheet is stretched and subjected to pressure, so the rubber sheet is generally a consumable item, and its lifespan ranges from 6,000 to 20,000 times. This lamination method has the following disadvantages: 1. First of all, the plastic sheet needs to be replaced every two months on average, resulting in higher lamination costs; 2. It is difficult to dispose of waste plastic sheets harmlessly; 3. The labor cost of replacing the rubber sheet, including transportation and replacement; 4. The time cost of replacing the rubber sheet. Each replacement requires downtime, resulting in loss of production capacity; 5. Electricity cost: replacing the rubber sheet requires preheating and baking; 6. Yield rate: Once the rubber sheet is damaged, it will directly affect the quality of components in the current process, resulting in degradation or scrapping.

A sealing ring is also fixedly embedded in the upper end of the upper positioning plate, and the sealing ring is in contact with the lower end of the upper heating plate. Tilt detection components are provided at both ends of the lower pressure plate, and high-strength cameras are also provided on the left and right sides of the lower pressure plate respectively. The high-strength cameras correspond to the tilt detection components, and both are connected to the control center signal.

[0007] In the above-mentioned solar photovoltaic module glue-free laminating machine structure, the arrangement of the bellows assembly and the lower pressure plate can replace the glue plate in the prior art, thereby realizing the lamination of solar photovoltaic modules without a glue plate, thereby effectively avoiding a series of problems caused by the glue plate, improving the lamination effect and reducing the lamination cost.

[0008] As a further improvement of the present application, the outer ends of the three guide shafts are all sleeved with guide copper sleeves, the guide copper sleeves are fixedly connected to the upper heating plate, and the inner wall of the guide copper sleeves is fixedly inlaid with a self-lubricating graphite layer.

[0009] As a further improvement of the present application, the tilt detection assembly includes an epitaxial plate fixedly connected to the lower pressure plate, a laser rangefinder fixedly connected to the lower end of the epitaxial plate, and an inclinometric light tube connected to the lower end of the epitaxial plate through an adaptive rod. The high-intensity camera is also installed at the lower end of the epitaxial plate, and the inclinometric light tube is located between the laser rangefinder and the high-intensity camera. The laser rangefinder is coaxially arranged with the corresponding inclinometric light tube.

[0010] As a further improvement of the present application, the adaptive rod includes a positioning seat fixedly connected to the extension plate and a vertical end fixedly connected to the middle of the inclinometer light tube, and the vertical end and the positioning seat are rotatably connected to each other.

DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1 The structure of a solar photovoltaic module non-glue laminator is shown, including a lower heating plate 2 fixedly connected to the laminator, an upper heating plate 1 with a control center is arranged above the lower heating plate 2, wherein an electric push rod or an electric oil cylinder or an electric air cylinder for driving the upper heating plate 1 is also arranged between the upper heating plate 1 and the laminator, two electric cylinders 4 are arranged at the upper end of the upper heating plate 1, and the electric cylinder 4 is used to drive the corrugated tube assembly 5 to realize the hot pressing of the photovoltaic module to be pressed, and the electric cylinder 4 is fixedly connected to the laminator, and a pressure strip 3 is arranged at the lower edge of the upper heating plate 1, and the pressure strip 3 and the upper heating plate 1 are connected by a connection The movable seat 102 is fixedly connected with bolts, and sealing rings are inlaid on the upper and lower surfaces of the pressure strip 3, and the sealing rings are squeezed and contacted with the upper heating plate 1. When the pressure strip 3 contacts the lower heating plate 2, the upper heating plate 1, the lower heating plate 2 and the pressure strip 3 jointly form a lamination cavity, and multiple upper heating plates 101 and multiple lower heating plates 201 are respectively installed on the end surfaces of the upper heating plate 1 and the lower heating plate 2 away from each other. A bellows assembly 5 is fixedly connected below the two electric cylinders 4, and the bellows assembly 5 movably penetrates the upper heating plate 1 and extends into the lamination cavity. The lower ends of the two bellows assemblies 5 are jointly fixedly connected with a lower pressing plate 6; The heating method of the upper heating plate 101 and the lower heating plate 201 is not limited, and can be one or more of electromagnetic heating, electric heating, oil heating, and lamp heating. The specific implementation can be selectively set according to actual conditions.

[0020] like Figure 2The bellows assembly 5 includes three guide shafts 53 that are fixedly connected to the extended ends of the electric cylinder 4, a lower positioning plate 55 that is fixedly connected to the lower ends of the three guide shafts 53, an upper positioning plate 51 that is fixed to the middle part of the lower end of the upper heating plate 1 by bolts, and a bellows 52 that is fixedly connected between the upper positioning plate 51 and the guide shafts 53. The multiple guide shafts 53 are movable through the upper heating plate 1 and the upper positioning plate 51 in turn and are located on the inner side of the bellows 52. The upper end of the upper positioning plate 51 is also fixedly inlaid with a sealing ring, and the sealing ring is in contact with the lower end of the upper heating plate 1. When in use, the photovoltaic component to be pressed is moved to the bottom of the lower pressing plate 6, and then the upper heating plate 1 is controlled to move downward to seal the lamination chamber. At this time, vacuum is drawn and heated to make the EVA glue at the center of the lamination component to be pressed melt, and at the same time, the internal bubbles overflow, and then the bellows assembly 5 and the lower pressing plate 6 are controlled to move downward to squeeze the photovoltaic component to be pressed to achieve lamination.

[0021] The outer ends of the three guide shafts 53 are all sleeved with guide copper sleeves 54, which are fixedly connected to the upper heating plate 1. The inner wall of the guide copper sleeve 54 is fixedly inlaid with a self-lubricating graphite layer to achieve self-lubrication, effectively ensuring the smoothness of the guide shaft 53 when passing through the upper heating plate 1 during lamination, and effectively ensuring the continuity during lamination.

[0022] like Fig.11 As shown, in a specific implementation, the bellows can be arranged outside the upper heating plate 1 according to actual needs, and the upper heating plate 101 can also be arranged in the lamination cavity according to actual needs.

[0023] In summary, by setting the bellows assembly 5 and the lower pressing plate 6, the Figure 3 The glue sheet in the prior art can realize the lamination of solar photovoltaic components without the glue sheet, thereby effectively avoiding a series of problems such as cost and lamination quality caused by the easy loss of the glue sheet.

[0024] The second implementation method: Based on the first embodiment, this embodiment adds a tilt detection component, and the rest of the parts are consistent with the first embodiment.

[0025] Figure 4-6As shown, both left and right ends of the lower pressing plate 6 are provided with tilt detection components, and high-intensity cameras 73 are also provided on the left and right sides of the lower pressing plate 6, respectively. The high-intensity cameras 73 correspond to the tilt detection components, and both are connected to the control center signal. The tilt detection component includes an extension plate 71 fixedly connected to the lower pressing plate 6, a laser rangefinder 72 fixedly connected to the lower end of the extension plate 71, and an inclinometric light tube 8 connected to the lower end of the extension plate 71 through an adaptive rod 9. The high-intensity camera 73 is also installed at the lower end of the extension plate 71, and the inclinometric light tube 8 is located between the laser rangefinder 72 and the high-intensity camera 73. The laser rangefinder 72 is coaxially arranged with the corresponding inclinometric light tube 8, so that when the extension plate 71 is in a horizontal state, the laser rangefinder 72 is synchronously horizontal, and the laser emitted by it can penetrate the axis of the inclinometric light tube 8, and as the number of laminations increases The guide shaft 53 may have accumulated tolerance due to wear in the process of passing through the upper heating plate 1 back and forth. When the accumulated tolerance is too large, the lower pressing plate 6 will be tilted, affecting the lamination quality. At this time, the extension plate 71 connected thereto is tilted synchronously, and the adaptive rod 9 is still vertically downward under the action of gravity. At this time, the coaxiality of the laser rangefinder 72 and the inclinometer light tube 8 changes, so that the laser cannot pass through the inclinometer light tube 8. When the tilt amplitude is small, the laser will fall on the inner wall of the light hole 801 after entering the light hole 801. The laser on one side falls on the inner wall of the inclinometer light tube 8, thereby causing local luminescence and discoloration on the upper surface of the inclinometer light tube 8, so that the abnormality can be discovered immediately and corresponding maintenance and repair can be carried out, thereby reducing the impact on lamination and reducing the occurrence of rework or unqualified products in subsequent batches.

[0026] like Figure 7 The adaptive rod 9 includes a positioning seat 92 fixedly connected to the extension plate 71 and a vertical end 91 fixedly connected to the middle of the inclinometer light tube 8. The vertical end 91 and the positioning seat 92 are rotatably connected to each other. Through the rotatable connection, when the extension plate 71 tilts with the lower pressure plate 6, the position of the inclinometer light tube 8 can be corrected under the action of gravity, and then it remains in a vertical state, thereby realizing a change in its coaxiality with the laser rangefinder 72, so as to facilitate the difference in the monitoring results.

[0027] like Figure 8-9The inclinometer light tube 8 includes a counterweight half column 81 and a 82 fixedly connected to the upper end of the counterweight half column 81. The centers of the counterweight half columns 81 and 82 form a light hole 801. The inner diameter of the light hole 801 is not greater than 3 times the diameter of the laser beam, so that the aperture is not easily affected by being too large to affect the accuracy of the monitoring result. 82 includes a plurality of light-shielding layers 822 and a plurality of light-displaying layers 821 respectively fixedly connected between two adjacent light-shielding layers 822. The light-shielding layers 822 are made of opaque shading materials, and the light-displaying layers 821 are made of transparent light-guiding materials. When the inclinometer light tube 8 and the laser rangefinder 7 are connected, the light-shielding layers 822 are made of opaque shading materials, and the light-displaying layers 821 are made of transparent light-guiding materials. When the axes are not aligned and the tilt amplitude is relatively large, the laser of the laser rangefinder 72 will have difficulty in entering the inclinometer light tube 8, or after entering the inclinometer light tube 8, it can only irradiate the inside of the inclinometer light tube 8 and cannot pass through the inclinometer light tube 8, and the laser beam on one side will irradiate a certain light-displaying layer 821 in the upper inner wall of the inclinometer light tube 8. At this time, under the light-guiding effect, the corresponding light-displaying layer 821 will change color and emit light. When the high-intensity camera 73 captures this phenomenon, it can be explained that the lower pressing plate 6 is tilted due to the accumulated tolerance, and corresponding processing needs to be carried out in time.

[0028] When the laser cannot penetrate into the inclinometer light tube 8, the data acquired by the laser rangefinder 72 will abnormally increase or decrease, which will be significantly different from the expected data projected onto the glass plate. Based on the phenomenon at the inclinometer light tube 8 and the data of the laser rangefinder 72, it is possible to detect whether the lower pressure plate 6 is tilted and the approximate tilt amplitude.

[0029] The two laser rangefinders 72 are not coaxially arranged, and there is a height difference between them. The laser beams emitted by the two laser rangefinders 72 just correspond to the upper and lower plates of the photovoltaic assembly to be pressed. The lower laser rangefinder 72 does not contact the upper surface of the lower heating plate 2 during lamination, so that the lasers emitted by the two laser rangefinders 72 can just fall on the two glass sheets respectively, so that it can monitor whether the glass sheets move during lamination, which is convenient for timely picking out products with excessive relative movement, reducing the workload of subsequent product qualification inspection, and at the same time facilitating the staff to detect abnormalities in time and reduce the continuous production of abnormal laminated products.

[0030] A laminating method for a solar photovoltaic module without adhesive plate laminating machine structure comprises the following steps: S1, such as Figure 4 First, the upper heating plate 1 is controlled to move upward to open the lamination chamber. At this time, the edge of the photovoltaic module to be pressed is first coated with a dark coating, and then the photovoltaic module to be pressed is moved to the target position in the lamination chamber, such as Figure 1 , and then the upper heating plate 1 is controlled to reset, so that the laminating chamber is in a sealed state, wherein the dark coating makes the light transmittance of the glass plate worse, so that when the laser falls on it, it is difficult to pass through the glass plate, so that the data obtained by the laser rangefinder 72 is relatively fixed; S2, start to evacuate the lamination chamber to make it in a vacuum state, so as to melt the EVA glue in the photovoltaic module to be pressed, and at the same time squeeze out the air in the EVA glue and exhaust the air from the lamination chamber; S3, control the extension of the bellows assembly 5 through the electric cylinder 4 so that the lower pressing plate 6 gradually moves downward and contacts the photovoltaic assembly to be pressed, and then turn on the tilt detection assembly to detect whether the lower pressing plate 6 is tilted on the one hand, and to locate the relative positions of the two glass plates of the photovoltaic assembly to be pressed on the other hand, and use two laser rangefinders 72 to measure the initial distance of the laser rangefinder 72 from the two glass plates of the photovoltaic assembly to be pressed respectively; S4, such as Figure 6-7 When the laser emitted by the laser rangefinder 72 can smoothly pass through the light hole 801, so that there is no local discoloration and luminescence on the oblique light tube 8, it means that the lower pressure plate 6 is not tilted, and the electric cylinder 4 continues to push the bellows assembly 5, thereby driving the lower pressure plate 6 to squeeze the photovoltaic components to be pressed for lamination. During this process, the two laser rangefinders 72 monitor the distance between the two glass plates and the corresponding laser rangefinders 72 in real time and compare it with the initial distance. When the measured data is the same as the initial distance, it means that the lateral relative position of the two glass plates has not changed, and lamination continues. When lateral deviation occurs, it can be fed back to the control center in real time to facilitate timely maintenance by the staff.

[0031] With the setting of the tilt detection component, the tilt of the lower pressure plate 6 can be monitored before lamination, so as to timely detect the situation that the lower pressure plate 6 is tilted due to the accumulation of errors caused by the up and down movement of the bellows component 5, thereby effectively ensuring the uniformity of lamination. During lamination, the two glass plates in the photovoltaic component to be pressed are monitored in real time, thereby effectively ensuring the stability of the entire lamination process, and timely detecting the relative displacement of the two glass plates, which is convenient for timely maintenance in case of abnormalities. It is not easy for batches of products to be scrapped due to relative errors, thereby effectively ensuring the yield rate.

[0032] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
