Description

Technical Field

[0001] The utility model relates to a double-sided heating component for a laminator, in particular to a double-sided heating component for a laminator applied to the field of laminating preparation of solar photovoltaic modules. Background Art

[0002] A photovoltaic module laminator is a core device in the production process of photovoltaic modules. Its main function is to press tempered glass plates, EVA, connected single solar cells, EVA, and photovoltaic module backplates into photovoltaic modules by means of vacuum hot pressing. The heating method of the photovoltaic module laminator, as well as its temperature control accuracy and temperature uniformity during the lamination process, are all closely related to the quality of the photovoltaic modules. When the tempered glass plate of the photovoltaic module enters the laminator chamber, it is prone to severe warping and deformation due to heat before being laminated.

[0003] The specification of Chinese Patent CN202088623U discloses a special laminator for BIPV double-layer glass modules, including an upper chamber of the laminator and a corresponding lower chamber heating platform. Since the upper and lower chambers of the laminator have heating functions at the same time, and upper and lower layer cooling devices are respectively provided at the discharging end of the laminator, the BIPV double-sided glass module is forced to cool in a vacuum state, solving the technical bottleneck that bubbles are easily generated during the lamination process of the BIPV double-layer glass module.

[0004] The specification of Chinese Patent CN207594477U discloses a double-sided heating laminator, including a workbench, a box cover, a first heating element and a second heating element. During the lamination process, the first heating element heats the silica gel plate, and both the upper and lower surfaces of the photovoltaic module are heated, thereby reducing the temperature difference between the upper and lower surfaces of the photovoltaic module, reducing the difficulty of the entire process control, shortening the heat transfer time, reducing the lamination process time, accelerating the production rhythm, improving the production capacity, and reducing the cost.

[0005] At present, there are two mainstream double-sided electric heating laminator technologies. One is that the lower heating is flat or dot matrix electric heating, and the upper heating is heating by a heating element. It is very difficult to achieve uniform distribution, and it is very difficult to maintain flatness after temperature rise, resulting in easy deformation and warping of the upper cover, affecting vacuum sealing and other drawbacks. The other is that the lower heating is flat or dot matrix electric heating, and the upper heating is infrared radiation heating. The process is complex, involving fixing, wiring, vacuum sealing and other problems. The lamp tube is made of glass and is easily damaged by force, and there are large deviations between the controlled temperature and the actual temperature. Summary of the Utility Model

[0006] Aiming at the above-mentioned prior art, the technical problem to be solved by the present utility model is that both mainstream double-sided electric heating laminator technologies have the disadvantages of easy deformation and damage.

[0007] To solve the above problems, the present utility model provides a double-sided heating component for a laminator, which includes a laminator main body. A lower heating plate and a heating sheet assembly are arranged on the lower side of the inner end of the laminator main body. A laminator upper cover is arranged at the upper end of the laminator main body. A finished product assembly is filled in the inner end of the laminator upper cover. The lower heating plate and the heating sheet assembly include a battery assembly. A silica gel plate is arranged at the inner end of the laminator upper cover. After the laminator upper cover is closed, a sealed cavity is formed. The silica gel plate divides the sealed cavity into two inner cavities. The finished product assembly is located in the lower inner cavity. An air inflation and pressurization component is externally connected to the lower inner cavity. A heat insulation backing plate is arranged at the inner end of the laminator upper cover. An upper heating sheet is arranged in the laminator upper cover. The upper heating sheet is closely attached to the inner side wall position of the laminator upper cover. A heating element is installed in the laminator upper cover. The lower heating plate and the heating sheet assembly cooperate with the finished product assembly, and the finished product assembly is located above the lower heating plate and the heating sheet assembly.

[0008] In the above double-sided heating component for a laminator, in this solution, the lower heating plate and the heating sheet assembly and the upper heating sheet are directly installed in the laminator main body and the laminator upper cover. The baking of the lower heating plate and the heating sheet assembly is more direct in temperature display and control. The strength requirement of the laminator upper cover can be reduced, and no additional heat insulation material is required. The heat distribution is uniform and the power density is consistent.

[0009] As a further improvement of the present application, a flatness detection strip is externally connected to the laminator main body, and a plurality of opening slots are provided below the flatness detection strip.

[0010] As a further improvement of the present application, a spring is fixedly connected to the upper inner wall of the opening slot, and a detection vertical strip is fixedly connected to the lower end of the spring.

[0011] As a further improvement of the present application, a contact inductor is fixedly connected to the inner side wall of the opening slot, and the outer side wall of the detection vertical strip cooperates with the contact inductor.

[0012] As another improvement of the present application, the flatness detection strip is located directly above the finished product assembly, and a plurality of detection vertical strips cooperate with the finished product assembly.

[0013] As a supplementary improvement of the present application, a heat insulation material is fixedly connected to the inner side wall of the laminator upper cover.

[0014] As a supplementary improvement of the present application, a plurality of pressing strips are arranged between the laminator upper cover and the laminator main body.

[0015] In summary, the present solution does not conduct temperature through the upper cover bottom plate in the prior art, but directly heats and bakes the silicone plate on the main body of the laminator, avoiding heat loss and deformation of the upper cover of the laminator. Therefore, the lower heating plate, the heating sheet assembly, and the upper heating sheet are directly installed in the main body of the laminator and the upper cover of the laminator to bake the lower heating plate and the heating sheet assembly, and directly control their temperatures. The temperature display and control are more direct, and the temperature range can reach two hundred degrees, which can reduce the strength requirements of the upper cover of the laminator and does not require additional thermal insulation materials. The heat is evenly distributed and the power density is consistent. Description of the Drawings

[0026] The following will describe in detail the two embodiments of the present application with reference to the drawings.

[0027] The first implementation method:

[0028] Figures 1-6 A double-sided heating component for a laminator is shown, which includes a laminator main body 1. A lower heating plate and a heating sheet assembly 10 are arranged on the lower side of the inner end of the laminator main body 1. A laminator upper cover 6 is arranged at the upper end of the laminator main body 1. A finished product assembly 16 is filled in the inner end of the laminator upper cover 6. The lower heating plate and the heating sheet assembly 10 include a battery assembly 4. A silica gel plate 3 is arranged at the inner end of the laminator upper cover 6. After the laminator upper cover 6 is closed, a sealed cavity is formed. The silica gel plate 3 divides the sealed cavity into two inner cavities. The finished product assembly 16 is located in the lower inner cavity. An air inflation and pressurization assembly is externally connected to the lower inner cavity. A heat insulation backing plate 5 is arranged at the inner end of the laminator upper cover 6. An upper heating sheet 7 is arranged in the laminator upper cover 6. The upper heating sheet 7 is closely attached to the inner side wall position of the laminator upper cover 6. A heating element 9 is installed in the laminator upper cover 6. The lower heating plate and the heating sheet assembly 10 cooperate with the finished product assembly 16, and the finished product assembly 16 is located above the lower heating plate and the heating sheet assembly 10.

[0029] Figures 1-6 It is shown that a heat preservation material 8 is fixedly connected to the inner side wall of the laminator upper cover 6, and a plurality of pressing strips 2 are arranged between the laminator upper cover 6 and the laminator main body 1.

[0030] Figures 1-6 It is shown that in this solution, the temperature is not conducted through the bottom plate of the laminator upper cover 6 in the prior art, but the silica gel plate 3 on the laminator main body 1 is directly heated by baking, avoiding heat loss and deformation of the laminator upper cover 6. Therefore, the lower heating plate and the heating sheet assembly 10 and the upper heating sheet 7 are directly installed in the laminator main body 1 and the laminator upper cover 6, and the lower heating plate and the heating sheet assembly 10 are baked, and its temperature is directly controlled. The temperature display and control are more direct, and the temperature range can reach two hundred degrees. The strength requirement of the laminator upper cover 6 can be reduced, and no additional heat preservation material is required. The heat distribution is uniform and the power density is consistent. Specifically, the upper heating sheet 7 is placed in the laminator upper cover 6. After the laminator upper cover 6 is closed, a sealed cavity is formed. The cavity is divided into upper and lower two cavities by the silica gel plate 3. The assembly is located in the lower cavity, and the upper cavity is used for air inflation and pressurization. A heating element 9 is installed in the laminator upper cover 6. The externally connected temperature control system controls the heating and temperature stability of each heating element 9. Each heating element 9 is individually temperature controlled. The silica gel plate 3 is directly baked by heating in the cavity. Compared with the traditional flexible structure heating sheet solution, the heating element 9 is located inside the cavity, and there is a heat insulation backing plate 5, so the heat utilization rate is relatively high, the temperature control is more direct, the heating rate of the lower heating plate and the heating sheet assembly 10 is effectively increased, and the entire lamination process time is shortened. In addition, the inner side wall of the laminator upper cover 6 is also provided with a heat preservation material 8 filled in the upper cover, which effectively isolates heat dissipation.

[0031] The second implementation method:

[0032] Figures 7-8 There is shown a double-sided heating component for a laminator. There is an evenness detection strip 11 externally connected to the main body 1 of the laminator. A plurality of opening slots 13 are formed in the lower part of the evenness detection strip 11. A spring 14 is fixedly connected to the upper inner wall of the opening slot 13. The lower end of the spring 14 is fixedly connected to a detection vertical strip 12. A contact inductor 15 is fixedly connected to the inner side wall of the opening slot 13. The outer side wall of the detection vertical strip 12 cooperates with the contact inductor 15. The evenness detection strip 11 is located directly above the finished product component 16, and a plurality of detection vertical strips 12 cooperate with the finished product component 16. At the same time, after the pressing and processing of the finished product component 16 in this solution is completed, it can be taken out and placed directly below the externally connected evenness detection strip 11 of the main body 1 of the laminator. The finished product component 16 is translated from directly below the evenness detection strip 11. When the detection vertical strip 12 touches the plane of the finished product component 16 and encounters an area in a bulging or warping state, the detection vertical strip 12 can be extruded upward. The upwardly moved detection vertical strip 12 contacts the contact inductor 15 inside the opening slot 13, and then an alarm signal can be sent to the externally connected control terminal, reducing the defective rate.

[0033] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
