Description

Technical Field

[0001] This utility model relates to the field of laminator technology, and more specifically to a pressure application structure for a flat-plate laminator. Background Technology

[0002] Currently, the pressure-applying part of the laminator mainly includes the upper box, the adhesive sheet, and the pressure frame. The adhesive sheet is pressed between the upper box and the pressure frame. The purpose of laminating the solar cell module (hereinafter referred to as the module) is achieved by applying pressure to the module through the adhesive sheet. However, the following problems exist: 1) The flatness of the laminated module is not high and the edge thickness is uneven; 2) The adhesive sheet needs to be replaced regularly during use. The adhesive sheet is a consumable, and the replacement and maintenance costs (materials, labor, etc.) are high.

[0003] Therefore, providing a flat-plate laminator pressure application structure is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a flat plate laminator pressure application structure to ensure lamination flatness, avoid replacing the adhesive sheet, and reduce costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flat-plate laminator pressure structure includes an upper chamber and a lower pressure frame, the upper chamber and the lower pressure frame being fastened together by quick clamps. It also includes a pressure plate, a vibration damping and lifting mechanism, and a sealing plate. The pressure plate is installed at the bottom of the upper chamber via the vibration damping and lifting mechanism. The outer side of the sealing plate is pressed between the upper pressure frame and the lower pressure frame of the upper chamber, and the inner side of the sealing plate extends and is fixed inside the pressure plate, thereby forming an upper chamber between the upper chamber, the sealing plate, and the pressure plate, and a lower chamber between the pressure plate, the sealing plate, the lower pressure frame, and the lower heating plate.

[0007] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0008] Using a pressure plate and a sealing plate in combination to replace the adhesive plate has several advantages. First, the pressure plate itself is flat and rigid, which can ensure that the entire plate is completely attached to the plane of the component, so that the stress on each part of the component is uniform during the lamination process, maintaining a consistent flatness. Second, it avoids the need to replace the adhesive plate, reducing costs.

[0009] Furthermore, it also includes a first buffer plate and a second buffer plate, wherein the first buffer plate, the pressure plate, and the second buffer plate are bonded together sequentially from top to bottom.

[0010] The beneficial effect of adopting the above-mentioned further technical solution is to provide a buffering effect when the pressure plate contacts the component.

[0011] Furthermore, it also includes a high-temperature cloth, which is bonded to the bottom of the second buffer plate.

[0012] Furthermore, the contact surface between the high-temperature cloth and the component has a shape that is high in the middle and low around the edges.

[0013] Furthermore, the pressure plate includes a pressure plate body and a pressure plate connecting plate, and the inner side of the sealing plate is located between the pressure plate body and the pressure plate connecting plate, and is connected together by bolts.

[0014] Furthermore, pneumatic silicone strips are installed between the pressure frame and the outer side of the sealing plate, as well as at the bottom of the pressure frame.

[0015] The beneficial effect of adopting the above-mentioned further technical solution is that when pressure is applied to the gas rubber silicone strip, due to the friction coefficient of the gas rubber silicone strip, the pressure applied to the gas rubber silicone strip can be converted into friction force, thereby tightening the sealing plate.

[0016] Furthermore, the vibration damping and lifting mechanism includes an outer shell, an inner shell, a spring column, a baffle, and a spring. The bottom of the outer shell is connected to the upper box by bolts. The inner shell is fixed inside the outer shell. The top of the spring column is located inside the inner shell, and the bottom of the spring column penetrates the inner shell and extends out of the outer shell, so that the column head at the bottom of the spring column is threadedly connected to the pressure plate. The baffle is fitted and fixed to the top of the spring column. The spring is fitted on the spring column and located between the baffle and the bottom of the inner shell.

[0017] The beneficial effect of adopting the above-mentioned further technical solution is that when sudden situations such as vacuum depressurization or sudden interruption of compressed air occur, the upper box will open. At this time, due to the gravity of the pressure plate, the spring column and the baffle on it will move down and the spring will be compressed. As a result, the pressure plate will be subjected to the upward elastic force generated by the spring, so that the pressure plate will open together with the upper box, ensuring that the pressure plate and the component are effectively separated after the cover is opened.

[0018] Furthermore, sealing rings are installed between the outer shell and the inner shell, as well as between the outer shell and the upper box.

[0019] The beneficial effect of adopting the above-mentioned further technical solution is to improve sealing performance.

[0020] Furthermore, a nut is welded to the center of the top surface of the pressure plate for threaded connection with the column head.

[0021] The beneficial effect of adopting the above-mentioned further technical solution is that it facilitates the connection between the pressure plate and the shock absorption lifting mechanism.

[0022] Furthermore, the spring is a heavy-duty spring. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-3 As shown, this utility model discloses a flat-plate laminator pressing structure, including an upper box 1, a lower pressure frame 2, a pressure plate 3, a vibration damping and lifting mechanism 4, and a sealing plate 5. The upper box 1 and the lower pressure frame 2 are fastened together by a quick clamp 6. The pressure plate 3 is installed at the bottom of the upper box 1 through the vibration damping and lifting mechanism 4. The pressure plate 3 is made of steel or hard aluminum. The sealing plate 5 is made of a high-temperature resistant flexible material. The outer side of the sealing plate 5 is pressed between the upper pressure frame and the lower pressure frame 2 of the upper box 1, and the inner side of the sealing plate 5 extends and is fixed inside the pressure plate 3, thereby forming an upper chamber between the upper box 1, the sealing plate 5, and the pressure plate 3, and a lower chamber between the pressure plate 3, the sealing plate 5, the lower pressure frame 2, and the lower heating plate. This utility model uses the pressure plate 3 and the sealing plate 5 to replace the adhesive plate. On the one hand, the pressure plate 3 itself is flat and rigid, which can ensure that the entire plate is completely attached to the plane of the component, so that the force on each part of the component is uniform during the lamination process, maintaining a consistent flatness. On the other hand, it avoids replacing the adhesive plate, reducing costs.

[0029] To further optimize the technical solution of this utility model, it also includes a first buffer plate 7 and a second buffer plate 8. The first buffer plate 7, the pressure plate 3 and the second buffer plate 8 are bonded together from top to bottom. The first buffer plate 7 and the second buffer plate 8 are both made of high temperature resistant flexible material, which can provide a buffering effect when the pressure plate 3 contacts the component.

[0030] To further optimize the technical solution of this utility model, a high-temperature cloth is also included, which is adhered to the bottom of the second buffer plate 8.

[0031] Understandably, all of the above adhesives use high-temperature resistant glue.

[0032] The contact surface between the high-temperature cloth and the component has a shape that is high in the middle and low around the edges.

[0033] Specifically, the pressure plate 3 includes a pressure plate body 31 and a pressure plate connecting plate 32. The inner side of the sealing plate 5 is located between the pressure plate body 31 and the pressure plate connecting plate 32, and they are connected together by bolts (countersunk bolts).

[0034] Understandably, the sealing plate 5 has evenly distributed round holes of the same diameter on its inner side, and the pressure plate body 31 has threaded blind holes corresponding to the sealing plate 5 around its perimeter (while ensuring the strength of the steel plate). The pressure plate connecting plate 32 has countersunk holes corresponding to the sealing plate 5 and the pressure plate body 31 to reduce the protrusion of the screw head.

[0035] To further optimize the technical solution of this utility model, a gas rubber silicone strip 9 is installed between the outer side of the lower pressure frame 2 and the sealing plate 5, as well as at the bottom of the lower pressure frame 2. When pressure is applied to the gas rubber silicone strip 9, due to the friction coefficient of the gas rubber silicone strip 9, the pressure applied to the gas rubber silicone strip 9 can be converted into friction force, thereby tightening the sealing plate 5.

[0036] Specifically, the vibration damping lifting mechanism 4 includes an outer shell 41, an inner shell 42, a spring column 43, a baffle 44, and a spring 45. The bottom of the outer shell 41 is connected to the upper box 1 by bolts; the inner shell 42 is fixed inside the outer shell 41; the top of the spring column 43 is located inside the inner shell 42, and the bottom of the spring column 43 penetrates the inner shell 42 and extends out of the outer shell 41, so that the bottom end of the spring column 43 is threadedly connected to the pressure plate 3; the baffle 44 is fitted and fixed to the top of the spring column 43; the spring 45 is fitted on the spring column 43 and is located between the baffle 44 and the bottom of the inner shell 42, wherein the spring 45 is a heavy-duty spring. When sudden situations such as vacuum depressurization or sudden interruption of compressed air occur, the upper box 1 performs an opening action. At this time, due to the gravity of the pressure plate 3, the spring column 43 and the baffle 44 on it move downward, and the spring 45 is compressed. Thus, the pressure plate 3 is subjected to the upward elastic force generated by the spring 45, so that the pressure plate 3 performs the opening action together with the upper box 1, ensuring that the pressure plate 3 is effectively separated from the component after the opening.

[0037] To further optimize the technical solution of this utility model, sealing rings are installed between the outer shell 41 and the inner shell 42, and between the outer shell 41 and the upper box 1, in order to improve the sealing performance.

[0038] To further optimize the technical solution of this utility model, a nut is welded to the center of the top surface of the pressure plate 3 for threaded connection with the column head, so as to facilitate the connection between the pressure plate 3 and the shock-absorbing lifting mechanism 4.

[0039] The working process of this utility model:

[0040] When the components are laminated, the pressure plate 3 moves towards the components under the vacuum of the lower chamber until the components are pressed tightly. At the same time, compressed air enters the upper chamber through the air inlet to provide positive pressure and realize the secondary pressure function of the components. After lamination is completed, the upper chamber is depressurized through the air inlet, and the lower chamber is filled with atmosphere through the vacuum port on the heating plate. The pressure plate 3 returns to its original position under the traction of the shock absorption and lifting mechanism 4, thereby ensuring that the components can smoothly enter the next process after lamination.

[0041] The upper chamber is connected to compressed air via a pipeline, and the lower chamber is connected to the vacuum system via the upper vacuum port of the heating plate. These are existing technologies and are the same as existing sheet-type laminators.

[0042] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
