[0001] This application relates to the field of photovoltaic module packaging technology, and in particular to a butyl tape application device and a battery packaging equipment. Background Technology

[0002] Thin-film batteries are power generation devices that use sunlight to generate direct current. Most of these components are waterproofed and sealed with butyl tape, which is a sealing and bonding material made of butyl rubber and polyisobutylene as the main raw materials and produced through a special process.

[0003] Currently, after the thin-film battery module is processed, butyl tape needs to be applied to the gaps between the battery panels. However, in the existing thin-film battery production line packaging process, there are common problems such as uneven application, detachment, or wrinkles of the butyl tape.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0035] This application discloses a butyl tape application device.

[0036] Please see Figure 1 One embodiment of a butyl tape application device provided in this application includes:

[0037] Fixed arm 1, pressure roller 3, and auxiliary device 2. Fixed arm 1 is a load-bearing structure used to provide a fixed mounting platform for pressure roller 3 and auxiliary device 2, and is also used to connect the moving device or robotic arm device. Its specific structure can be designed and modified according to actual needs without limitation.

[0038] The pressure roller 3 is rotatably mounted on the bottom end of the fixed arm 1.

[0039] The auxiliary device 2 is installed on one side of the fixed arm 1 in a direction perpendicular to the rotation center line of the pressure roller 3 (under this design, the auxiliary device 2 can continuously deliver heat in the direction of the pressure roller 3, realizing simultaneous rolling and heating). The auxiliary device 2 is used to deliver heat vertically downward.

[0040] The butyl tape application device designed in this application heats the surface of the workpiece (such as glass) to be coated by means of an auxiliary device 2, thereby increasing the temperature of the workpiece surface and improving the adhesion of the butyl tape, making it easier to apply to the workpiece surface. The fixed arm 1, driven by the moving device, causes the pressure roller 3 to squeeze and roll on the butyl tape, thereby ensuring that the butyl tape is evenly applied to the workpiece surface. By combining heating and rolling, the instability of butyl tape application due to low adhesion is effectively avoided, improving the uniformity and tightness of the butyl tape application, and increasing the application efficiency.

[0041] The above is Embodiment 1 of a butyl tape application device provided in this application. The following is Embodiment 2 of a butyl tape application device provided in this application. Please refer to the following for details. Figures 1 to 2 .

[0042] Based on the solution of Embodiment 1 above:

[0043] Furthermore, the auxiliary device 2 is detachably connected to the fixed arm 1.

[0044] If auxiliary device 2 malfunctions, the detachable connection allows maintenance personnel to quickly remove it from the fixed arm 1 for individual inspection, adjustment, or replacement of parts, without having to disassemble and reassemble the entire application device, making maintenance more convenient. Detachable connection methods include bolt connections, snap-fit ​​connections, etc., with no specific restrictions.

[0045] Furthermore, the auxiliary device 2 is a hot air blower. Compared with the heat radiation method, the hot air method can better transfer heat to the surface of the workpiece to be glued.

[0046] Furthermore, taking the design of a hot air blower as an example, the auxiliary device 2 includes a device housing 21, a fan 22, and a heater 23.

[0047] The device housing 21 has an air outlet 214 at the bottom and an air inlet 213 on the side or top. A fan 22 is installed in the device housing 21 to deliver air to the air outlet 214. A heater 23 is installed in the device housing 21 and is located between the fan 22 and the air outlet 214 to heat the passing air.

[0048] The work process is as follows:

[0049] When the fan 22 operates, it creates a negative pressure inside the device housing 21, causing outside air to be drawn into the device housing 21 from the air inlet 213 on the side or top of the device housing 21.

[0050] The fan 22 rotates continuously, pushing the intake air toward the outlet 214 to form a stable airflow channel, ensuring that the air can flow continuously within the device.

[0051] When air flows through heater 23, located between fan 22 and air outlet 214, heater 23 heats the air. Due to the heat exchange between the air and heater 23, the air absorbs heat and its temperature rises rapidly, thus becoming hot air.

[0052] The heated air, propelled by the fan 22, is blown out from the air outlet 214 at the bottom of the device housing 21 and reaches the target area, thereby achieving heat transfer to the target object.

[0053] Furthermore, heater 23 is a heating wire. The heating wire has high resistance, and when current passes through it, electrical energy can be quickly converted into heat energy, allowing the air flowing through it to rapidly increase in temperature in a short time.

[0054] Of course, heater 23 can also be a ceramic heating element, an infrared heating tube, a PTC heating element, etc., and there are no specific restrictions.

[0055] Furthermore, the device housing 21 includes an upper housing 211 and a lower housing 212 detachably connected to the upper housing 211. The fan 22 is installed in the upper housing 211, and the heater 23 is installed in the lower housing 212.

[0056] When the fan 22 or heater 23 malfunctions, the upper housing 211 and lower housing 212 are detachably connected, allowing maintenance personnel to easily disassemble them for inspection, replacement, or cleaning. For example, if the motor of the fan 22 is damaged, simply opening the upper housing 211 allows easy access to the fan 22 components for disassembly and replacement, eliminating the need for complex disassembly of the entire hot air blower. This significantly reduces maintenance time, costs, and difficulty, and improves equipment availability and maintenance efficiency.

[0057] Furthermore, the bottom of the lower housing 212 is inverted conical. The inverted conical design allows the hot airflow blown out by the hot air blower to gradually converge at the bottom, enhancing the concentration and velocity of the airflow. This converged airflow can more accurately transfer heat to the target object, improving heat transfer efficiency.

[0058] Furthermore, the upper housing 211 and the lower housing 212 are magnetically or snap-fit ​​connected. Magnetic and snap-fit ​​connections make disassembly and assembly more convenient and quick, effectively improving disassembly and maintenance efficiency. Of course, bolt connections and other methods are also possible, and there are no specific limitations.

[0059] Furthermore, it also includes a wheel frame 4, with the pressure roller 3 rotatably mounted on the wheel frame 4.

[0060] The wheel frame 4 is detachably mounted on the bottom of the fixed arm 1.

[0061] The addition of a wheel frame 4 facilitates the installation of the pressure roller 3 and allows for a detachable connection between the pressure roller 3 and the fixed arm 1, making it convenient for the pressure roller 3 to be replaced and maintained.

[0062] For detachable connection methods, there are no restrictions, such as bolt connection or snap-fit ​​connection.

[0063] This application also discloses battery packaging equipment, including an equipment body and a butyl tape application device.

[0064] The foregoing has provided a detailed description of a butyl tape application device and a battery encapsulation equipment provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
