Description

Technical Field

[0001] This utility model relates to the field of glueless laminate press technology, and in particular to a pressure-sensing glueless laminate press. Background Technology

[0002] The laminator laminates solar cell modules under high temperature and vacuum conditions. During the vacuum process, the pressure difference between the silicone plate and the upper and lower chambers is used to pressurize the module. After the cells are connected in series on the back and pass inspection, the cell strings, glass, and cut EVA, glass fiber, and backsheet are laid out in a specific layer, ready for lamination. A primer is applied to the glass beforehand to increase the adhesion strength between the glass and EVA. During laying, the relative positions of the cell strings and other materials such as glass are ensured, and the distance between the cells is adjusted to lay a good foundation for lamination. (Laying layers: from bottom to top: tempered glass, EVA, cell, EVA, glass fiber, backsheet). Module lamination involves placing the laid cells into the laminator, removing the air from the module by vacuuming, then heating to melt the EVA and bond the cells, glass, and backsheet together; finally, the module is cooled and removed. The lamination process is a crucial step in module production, and the lamination temperature and time are determined by the properties of EVA. When using fast-curing EVA, the lamination cycle time is approximately 25 minutes. The curing temperature is 150℃. As a key piece of equipment in the production of solar cell modules, the technological development of the solar cell module laminator directly affects the cost of module production.

[0003] Glueless lamination is an emerging technology and is not yet widely adopted. Its core drawback is that the pressure cannot be accurately controlled, making it impossible to ensure precise pressure control on the modules and thus avoid the risk of defective cells caused by lamination. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pressure-sensing glue-free laminator, which aims to improve the problem that the pressure cannot be accurately controlled in the prior art and that the components cannot be accurately controlled under pressure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pressure-sensing glue-free laminate press, comprising a lower heating plate, with uniformly distributed lower heating elements fixedly connected to the lower side of the lower heating plate, an assembly body fixedly connected to the upper side of the lower heating plate, sealing frames fixedly connected to both sides of the upper part of the lower heating plate, an upper heating plate fixedly connected to the upper side of the sealing frames, uniformly distributed upper heating elements fixedly connected to the lower side of the upper heating plate, connecting rods slidably connected to both sides of the interior of the upper heating plate, a drive connecting plate fixedly connected to the top of the connecting rod, a pressure plate fixedly connected to the bottom of the connecting rod, sealing bellows assemblies fixedly connected to both sides of the lower part of the drive connecting plate, uniformly distributed guide rods fixedly connected to the lower side of the drive connecting plate, and a sensing component provided on the upper side of the upper heating plate, the sensing component being used to measure the lamination pressure of the pressure plate.

[0006] As a further description of the above technical solution:

[0007] The sensing component includes a pressure sensor, which is disposed on the upper side of the upper heating plate, and a pressure detection seat is fixedly connected to the lower side of the drive connecting plate.

[0008] As a further description of the above technical solution:

[0009] The two guide rods are respectively disposed on both sides of the connecting rod, and the two guide rods are slidably connected inside the upper heating plate.

[0010] As a further description of the above technical solution:

[0011] The two sealed bellows assemblies are respectively fixedly connected to the upper two sides of the upper heating plate.

[0012] As a further description of the above technical solution:

[0013] The pressure plate is slidably connected to the lower heating plate and the upper heating plate on the adjacent side.

[0014] As a further description of the above technical solution:

[0015] The pressure detection seat is slidably connected to the upper side of the pressure sensor.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, the pressure plate presses downwards, bringing the pressure detection seat into contact with the pressure sensor. As the pressure plate continues to press down, pressure is generated at the contact surface between the pressure detection seat and the pressure sensor, and this pressure is fed back to the system through the pressure sensor. Before use, the pressure sensor needs to be calibrated using a resistive strain gauge. The device can only be used after the data has been calibrated. Multiple pressure sensors can also be configured, with each group's pressure adjusted based on feedback. This solves the problem of current hard pressure methods being unable to accurately measure the actual pressure on components, effectively controlling the pressure of the pressure plate lamination.

[0018] In this invention, the pressure sensor is installed in a quick-release manner, which facilitates installation and removal. It is installed during process testing and can be removed after testing is completed. Attached Figure Description

[0023] 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.

[0024] Reference Figure 1 , Figure 2This utility model provides an embodiment of a pressure-sensitive adhesive-free laminate press, comprising a lower heating plate 1, with uniformly distributed lower heating elements 2 fixedly connected to the lower side of the lower heating plate 1, an assembly body 3 fixedly connected to the upper side of the lower heating plate 1, sealing frames 4 fixedly connected to both sides of the upper part of the lower heating plate 1, an upper heating plate 5 fixedly connected to the upper side of the sealing frame 4, and uniformly distributed upper heating elements 6 fixedly connected to the lower side of the upper heating plate 5. Connecting rods 7 are slidably connected to both sides of the interior of the upper heating plate 5, with the top of the connecting rods 7... A drive connecting plate 10 is fixedly connected to the end of the connecting rod 7, a pressure plate 9 is fixedly connected to the bottom end of the connecting rod 7, a sealing bellows assembly 8 is fixedly connected to both sides of the lower part of the drive connecting plate 10, a uniformly distributed guide rod 13 is fixedly connected to the lower side of the drive connecting plate 10, a sensing component is provided on the upper side of the upper heating plate 5, the sensing component is used to measure the lamination pressure of the pressure plate 9; the sensing component includes a pressure sensor 11, the pressure sensor 11 is provided on the upper side of the upper heating plate 5, and a pressure detection seat 12 is fixedly connected to the lower side of the drive connecting plate 10.

[0025] When the pressure plate 9 is pressed down, the pressure detection seat 12 and the pressure sensor 11 begin to contact. During the continuous downward pressure of the pressure plate 9, pressure is generated at the contact surface between the pressure detection seat 12 and the pressure sensor 11, and this pressure is fed back to the system through the pressure sensor 11. Before use, the pressure sensor 11 needs to be calibrated using a resistance strain gauge. It can only be used after the data has been calibrated. The pressure sensor 11 can also be set into multiple groups, and the pressure of each group can be adjusted by feedback. This solves the problem that current hard pressure testing cannot accurately measure the actual pressure that components can withstand.

[0026] Reference Figure 1 , Figure 2 Two guide rods 13 are respectively set on both sides of the connecting rod 7, and the two guide rods 13 are slidably connected to the inside of the upper heating plate 5; two sealing bellows assemblies 8 are respectively fixedly connected to the upper two sides of the upper heating plate 5; the pressure plate 9 is slidably connected to the side of the lower heating plate 1 and the upper heating plate 5 that are close to each other; the pressure detection seat 12 is slidably connected to the upper side of the pressure sensor 11.

[0027] Two guide rods 13 are respectively set on both sides of the connecting rod 7, and the two guide rods 13 are slidably connected inside the upper heating plate 5, which serves to support and limit the connecting rod 7; two sealing bellows assemblies 8 are respectively fixedly connected to the upper sides of the upper heating plate 5, which serves to fix and support the sealing bellows assemblies 8; a pressure plate 9 is slidably connected to the side of the lower heating plate 1 and the upper heating plate 5 that is close to each other, which serves to effectively control and measure the pressure of the pressure plate 9; a pressure detection seat 12 is slidably connected to the upper side of the pressure sensor 11, which serves to accurately detect the pressure.

[0028] Working Principle: When using this device, pressure sensor 11 and pressure detection seat 12 are installed above the upper heating plate 5. When the pressure plate 9 is working, it presses downwards, and the pressure detection seat 12 and pressure sensor 11 begin to contact. During the continuous downward pressing of the pressure plate 9, pressure is generated at the contact surface between the pressure detection seat 12 and pressure sensor 11, and this pressure is fed back to the system through the pressure sensor 11. Before using the entire set of equipment, the pressure sensor 11 needs to be calibrated using a resistance strain gauge. It can only be used after the data is calibrated. The pressure sensor 11 can also be set into multiple groups, and the pressure of each group can be adjusted by feedback. This sets the output data of the pressure plate 9 driving device, which solves the problem that the actual pressure borne by the component cannot be measured by hard pressure at this stage, and effectively controls and measures the lamination pressure of the pressure plate 9.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
