Technical Field

[0001] This utility model relates to the technical field of solar cell string bonding device and its infrared lamp box, and in particular to a solar cell string bonding device and its infrared lamp box. Background Technology

[0002] A solar cell is a thin, photovoltaic semiconductor wafer that generates electricity directly from sunlight. It is one of the key components of a solar photovoltaic power generation system. When sunlight shines on the cell, the light energy is absorbed and converted into electrical energy, producing direct current. This current can be stored in the cell or converted into alternating current by an inverter to meet the electricity needs of households or businesses.

[0003] Existing solar cell stringing devices typically use an infrared lamp box for welding multiple solar cells. However, the infrared lamp box is usually a single unit, which means that the infrared lamps and controllers inside cannot be regularly inspected. If some parts malfunction, they cannot be maintained or replaced in a timely manner, resulting in uneven irradiation of the solar cells and a tendency for cold solder joints. To address this, we provide a solar cell stringing device and its infrared lamp box. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a solar cell string welding device and its infrared lamp box, comprising: a lifting platform, a box mechanism on one side of the lifting platform, the box mechanism including a top plate, the top plate being fixedly connected to the lifting platform, a connecting mechanism at the bottom of the top plate, the connecting mechanism including a baffle, a locking rod fixedly connected to one side of the baffle, a fixing block on one side of the baffle, the fixing block being fixedly connected to the top plate, an angled block sleeved inside the fixing block, the angled block being slidably connected to the fixing block, a slider fixedly connected to one end of the angled block, the slider being sleeved inside the fixing block, the slider being slidably connected to the fixing block, a spring on one side of the slider, the two ends of the spring being fixedly connected to the inner wall of the fixing block and the outer surface of the slider respectively, a moving block fixedly connected to one end of the slider, an infrared lamp body at the bottom of the top plate, and an outer plate fixedly connected to the outer surface of the top plate.

[0006] In a preferred embodiment, the inner side of the outer side plate is provided with a perforated plate, the perforated plate is fixedly connected to the outer side plate, a reflective material layer is provided on the side of the perforated plate near the infrared lamp body, the reflective material layer is fixedly connected to the perforated plate, and a blower module is sleeved inside the top plate.

[0007] In a preferred embodiment, the blower module is fixedly connected to the top plate, and the bottom of the top plate is provided with a controller. There are two controllers, and the controllers are fixedly connected to the outer side plate.

[0008] In a preferred embodiment, the bottom of the controller is provided with an elastic clip, which is fixedly connected to the controller. The elastic clip is sleeved on the outer surface of the infrared lamp body, and a steel wire is sleeved inside the outer side plate.

[0009] In a preferred embodiment, the steel wire is slidably connected to the outer side plate, and a second spring is sleeved on the outer surface of the steel wire, with the two ends of the second spring respectively fixedly connected to the outer surface of the steel wire and the outer side plate.

[0029] 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.

[0030] Example 1

[0031] like Figures 1-9 As shown, this utility model provides a technical solution: a solar cell string bonding device and its infrared lamp box, including: a lifting platform 1, a box mechanism 2 on one side of the lifting platform 1, the box mechanism 2 including a top plate 21, the top plate 21 being fixedly connected to the lifting platform 1, a connecting mechanism 4 at the bottom of the top plate 21, the connecting mechanism 4 including a baffle 41, a locking rod 42 fixedly connected to one side of the baffle 41, a fixing block 43 on one side of the baffle 41, the fixing block 43 being fixedly connected to the top plate 21, a chamfered block 44 sleeved inside the fixing block 43, the chamfered block 44 being slidably connected to the fixing block 43, a slider 45 fixedly connected to one end of the chamfered block 44, the slider 45 being sleeved inside the fixing block 43, the slider 45 being slidably connected to the fixing block 43, a spring 46 on one side of the slider 45, the two ends of the spring 46 being fixedly connected to the fixing block respectively. On the inner wall of 43 and the outer surface of slider 45, a moving block 47 is fixedly connected to one end of slider 45. An infrared lamp body 22 is provided at the bottom of top plate 21. An outer side plate 23 is fixedly connected to the outer surface of top plate 21. A mesh plate 24 is provided on the inner side of outer side plate 23. Mesh plate 24 is fixedly connected to outer side plate 23. A reflective material layer 25 is provided on the side of mesh plate 24 near infrared lamp body 22. Reflective material layer 25 is fixedly connected to mesh plate 24. A blower module 26 is sleeved inside top plate 21. Blower module 26 is fixedly connected to top plate 21. A controller 27 is provided at the bottom of top plate 21. There are two controllers 27. The controllers 27 are fixedly connected to outer side plate 23. An elastic clip 28 is provided at the bottom of controller 27. The elastic clip 28 is fixedly connected to controller 27. The elastic clip 28 is sleeved on the outer surface of infrared lamp body 22.

[0032] In this embodiment, a locking rod 42 is provided, which can be installed into the fixing block 43, thereby pressing the fixing block 43 and allowing it to slide. Simultaneously, a slot is provided on the locking rod 42 that engages with the angled block 44, allowing the angled block 44 to engage with the locking rod 42, thus stabilizing the baffle 41. A moving block 47 is provided, which can move the angled block 44 using a slider 45, thereby releasing the engagement between the locking rod 42 and the angled block 44, allowing the baffle 41 to separate from the top plate 21 and the outer side plate 23. An elastic clip 28 is provided, which can clamp onto the end of the infrared lamp body 22. The infrared lamp body 22 can remain stable. With the connection of the elastic clip 28, the infrared lamp body 22 can be connected to the controller 27. The controller 27 can control the infrared lamp body 22 individually or simultaneously, making the use of multiple infrared lamp bodies 22 more flexible. This ensures that each infrared lamp body 22 works in the predetermined working state, thereby ensuring the infrared welding effect and avoiding incomplete or over-welded soldering. At the same time, the emission window at the bottom of the outer plate 23 is related to the arrangement of the infrared lamp bodies 22. Thus, the infrared lamp bodies 22 placed inside the outer plate 23 can smoothly irradiate the connection between the solar cell body 32 and the solder ribbon 33 after generating heat.

[0033] Example 2

[0034] like Figures 1-9 As shown, a steel wire 29 is sleeved inside the outer side plate 23, and the steel wire 29 is slidably connected to the outer side plate 23. A spring 201 is sleeved on the outer surface of the steel wire 29, and the two ends of the spring 201 are fixedly connected to the outer surface of the steel wire 29 and the outer side plate 23, respectively. A welding mechanism 3 is provided on one side of the elevator 1. The welding mechanism 3 includes a welding table 31. A solar cell body 32 is provided on the top of the welding table 31, and a welding strip 33 is provided on the top of the welding table 31.

[0035] In this embodiment, a perforated plate 24 with through holes is provided, allowing the air blowing module 26 to cool the infrared lamp body 22 through the perforated plate 24. A steel wire 29, possessing high hardness, high temperature resistance, wear resistance, and tensile strength, is provided to tightly press the solar cell body 32 and welding strip 33 placed on the welding table 31. Simultaneously, the steel wire 29 does not obstruct the emission window on the outer side plate 23. Furthermore, a second spring 201 is provided, effectively eliminating the loosening of the steel wire 29 due to thermal expansion from room temperature to several hundred degrees Celsius during welding. This results in a tighter connection between the solar cell body 32 and the welding strip 33, ensuring welding quality.

[0036] Working principle:

[0037] like Figures 1-9 As shown, in use, a certain number of solar cell bodies 32 and welding ribbons 33 can be placed first. Their placement is appropriate, corresponding to the emission window at the bottom of the outer side plate 23, ensuring that the solar cell bodies 32 and welding ribbons 33 can be welded together under the heat of the infrared lamp body 22. Then, the lifting platform 1 is activated, using it to move the entire housing mechanism 2 downwards until the steel wire 29 can tightly press and fix the solar cell bodies 32 and welding ribbons 33. Next, the controller 27 and elastic clamp 28 control the infrared lamp body 22, causing it to generate heat. Part of the heat generated by the infrared lamp body 22 is reflected by the reflective material layer 25, thus illuminating the connection between the solar cell bodies 32 and welding ribbons 33 through the emission window, melting the welding ribbons 33, thereby illuminating multiple solar cells. The solar cell body 32 is welded together. After welding, the infrared lamp body 22 can be turned off by the controller 27 and the elastic clamp 28, so that the infrared lamp body 22 no longer generates heat. Then the blower module 26 is activated. The airflow generated by the blower module 26 can reach the infrared lamp body 22 and the welding table 31 through the mesh plate 24, so that the temperature of the infrared lamp body 22 and the welded solar cell body 32 can be reduced. If the infrared lamp body 22 and the controller 27 need to be inspected, the moving block 47 can be slid first. When the moving block 47 slides, it will drive the slider 45 to move. At this time, the slider 45 will drive the angled block 44 to disengage from the clamp 42, and the slider 45 will compress the spring 46, so that the spring 46 generates elastic force. When the angled block 44 is completely disengaged from the clamp 42, the baffle 41 can be removed, so that the inspection work can be carried out.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
