Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module production technology, and in particular to a sintering furnace belt device. Background Technology

[0002] Currently, in the screen printing process of the photovoltaic industry, sintering furnaces are used to sinter the printed solar cells. The furnace belts of the sintering furnaces in the screen printing process are basically the same type, that is, they use a mesh structure with pins on both sides to directly support the solar cells from both sides. This support method can minimize the contact area between the furnace belt and the solar cells and avoid defects in the aluminum back field after sintering caused by the furnace belt pins contacting the aluminum back field of the solar cells.

[0003] However, the current mesh structure of sintering furnace belts has many problems. The mesh structure furnace belt is a whole, and the connection between the two sides of the furnace belt is strong. When the spoke wheels are not installed properly or the angle difference between the front and rear ends is large, abnormal phenomena such as furnace belt deviation and furnace belt vibration will inevitably occur, which are time-consuming and labor-intensive to troubleshoot and deal with. At the same time, the mesh structure furnace belt has a large shading area under the battery, which affects the sintering effect, requires higher sintering temperature for sintering, requires higher lamp power, and increases power consumption. The large surface area of ​​the mesh structure requires regular cleaning of the entire furnace belt during daily production. Otherwise, dust generated by volatile organic compounds in the slurry will continue to accumulate on the surface of the furnace belt, further affecting the sintering effect, and in severe cases, leading to poor sintering.

[0004] Therefore, it is necessary to design a sintering furnace belt device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sintering furnace belt device that is stable in operation and highly compatible.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sintering furnace belt device, which includes multiple furnace belts and a drive assembly for driving the furnace belts to move horizontally. The furnace belt includes a strip-shaped furnace belt body and two furnace belt pins disposed on the furnace belt body for supporting the battery cells. The furnace belt bodies of the multiple furnace belts are arranged in parallel, and the two ends of the furnace belt bodies are respectively fixed on the drive assembly. The two furnace belt pins on each furnace belt body are arranged opposite each other along the length direction of the furnace belt body.

[0007] As a further improvement of the present invention, the furnace belt ejector pin includes a first support rod and a second support rod arranged sequentially along the length direction of the furnace belt body. The first support rod is arranged vertically, and the second support rod is arranged inclined. The upper ends of the first support rod and the second support rod form the apex angle of the furnace belt ejector pin.

[0008] As a further improvement of this utility model, on the same furnace belt body, the second support rods of the two furnace belt ejector pins are close to each other.

[0009] As a further improvement of this utility model, the first support rod and the second support rod are respectively welded to the furnace belt body.

[0010] As a further improvement of the present invention, a sliding mounting block is provided between the furnace belt ejector pin and the furnace belt body. The furnace belt body has a sliding groove arranged along its length direction, and the sliding mounting block moves along the sliding groove.

[0011] As a further improvement of this utility model, a fastening nut for fixing the sliding mounting fastener is provided on the furnace belt body at a position corresponding to the slide groove.

[0012] As a further improvement of the present invention, the furnace belt body is a cuboid frame, the sliding mounting block is located between the two upper edges of the cuboid frame, and the sliding groove is opened on the opposite sides of the two edges.

[0013] As a further improvement of the present invention, the driving assembly includes two chains located at both ends of the furnace belt, a motor driving the chains, and transmission gears.

[0014] As can be seen from the above technical solutions, the sintering furnace belt device of this utility model has the following advantages:

[0015] 1. By using multiple parallel furnace belt bodies in conjunction with the drive assembly, continuous and stable transmission of solar cells within the sintering furnace can be achieved, improving production efficiency and transmission stability. Two furnace belt ejector pins support the solar cells, effectively preventing direct contact between the solar cells and the furnace belt body, reducing friction and damage risks, and ensuring the integrity and quality of the solar cells during transmission.

[0016] 2. Compared with the existing mesh structure furnace belt, the multiple parallel furnace belt bodies can effectively solve the problems of time-consuming and labor-intensive installation and maintenance, large surface area that easily accumulates dust and requires regular overall cleaning, and greatly shorten the time for daily maintenance.

[0017] 3. The two ends of the strip-shaped furnace belt body are fixed on the chains on both sides for transmission, which makes the furnace belt body more time-saving and labor-saving during installation. At the same time, this type of furnace belt will not have problems such as belt speed fluctuation, poor battery sintering, and fragmentation caused by furnace belt deviation during the transportation process.

[0018] 4. The adjustable spacing of the furnace belt ejector pins is compatible with various sizes of solar cells, greatly reducing changeover time. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figure 1 As shown, this utility model provides a sintering furnace belt device, which includes multiple furnace belts 20 and a drive assembly 10 for driving the furnace belts 20 to move horizontally.

[0024] Please participate together Figure 2 As shown, the furnace belt 20 includes a strip-shaped furnace belt body 21 and two furnace belt pins 22 disposed on the furnace belt body 21 for supporting the battery cells. The furnace belt bodies 21 of multiple furnace belts 20 are arranged in parallel. The two ends of the furnace belt body 21 are respectively fixed on the drive assembly 10. The two furnace belt pins 22 on each furnace belt body 21 are arranged opposite each other along the length direction of the furnace belt body 21.

[0025] The furnace belt ejector pin 22 includes a first support rod 221 and a second support rod 222 arranged sequentially along the length of the furnace belt body 21. The first support rod 221 is vertically arranged, and the second support rod 222 is inclined. The upper ends of the first support rod 221 and the second support rod 222 form the apex angle of the furnace belt ejector pin 22. On the same furnace belt body 21, the second support rods 222 of the two furnace belt ejector pins 22 are close to each other. The structure of the first support rod 221 being vertically arranged and the second support rod 222 being inclined, with their upper ends forming an apex angle, helps the solar cells slide smoothly into and out of the ejector pin support area during the transport process, reducing jamming. The apex angle structure can accurately position the solar cells, improve the stability and reliability of the support, ensure that the solar cells maintain the correct posture during the transport process, and facilitate the accurate execution of subsequent sintering processes. The second support rods 222 of the two furnace belt ejector pins 22 on the same furnace belt body 21 are close to each other. This arrangement makes the solar cells constrained towards the center during the transmission process, further enhancing the stability of the solar cell transmission, preventing the solar cells from shifting laterally or falling during the transmission process, and ensuring the accuracy of the solar cell transmission path.

[0026] The first support rod 221 and the second support rod 222 can be fixed to the furnace belt body 21 by welding. Please refer to the following: Figure 3As shown, in this embodiment, the furnace belt ejector pin 22 and the furnace belt body 21 are slidably connected by a sliding mounting block 23. Specifically, the furnace belt body 21 has a groove along its length, and the sliding mounting block 23 moves along the groove. A fastening nut 24 is provided on the furnace belt body 21 at a position corresponding to the groove to fix the sliding mounting block 23. Depending on the size of the solar cells, the furnace belt ejector pin 22 can be pre-positioned, and then the fastening nut 24 can be tightened to fix its position. The sliding mounting block 23 and the corresponding groove between the furnace belt ejector pin 22 and the furnace belt body 21 allow the furnace belt ejector pin 22 to move along the length of the furnace belt body 21. This allows for flexible adjustment of the furnace belt ejector pin's position according to different sizes and specifications of solar cells, improving the versatility and adaptability of the furnace belt device and meeting diverse production needs.

[0027] The furnace belt body 21 is a cuboid frame, and the sliding mounting block 23 is located between the two upper edges 211 of the cuboid frame. The sliding groove is opened on the opposite sides of the two edges 211. This design improves the strength and rigidity of the furnace belt body 21, making it less prone to deformation during transmission. On the other hand, it provides a reasonable installation space and guiding structure for the sliding mounting block 23 and the furnace belt ejector pin 22, ensuring the smoothness and stability of the furnace belt ejector pin 22's movement.

[0028] The drive assembly 10 includes two chains 11 located at both ends of the furnace belt 20, a motor driving the chains, and transmission gears. Each chain can be driven by a separate motor or by the same motor with a compatible transmission assembly; this is not a limitation. The drive assembly uses a combination of chains, motors, and transmission gears. The motor drives the chains to rotate through the transmission gears, providing a stable and reliable driving force for the furnace belt, enabling uniform and smooth movement of the belt. Chain drive has advantages such as high transmission efficiency, strong load-bearing capacity, and long service life, and can meet the needs of long-term continuous operation of the sintering furnace, ensuring the reliability and stability of the entire furnace belt device.
