Technical Field
[0001] The utility model relates to the technical field of reflow soldering furnace conveying, in particular to a segmented mesh belt conveying mechanism of a reflow soldering furnace. Background Art
[0002] During the reflow soldering process, products are transported by a conveyor belt within the conveyor system. The belt's speed is programmable and controllable. Since belt speed directly affects the reflow soldering temperature profile, its stability is crucial. However, in addition to belt speed stability, the smoothness of the conveyor's mechanical movement is also a key factor influencing product soldering quality. Furthermore, with the advancement of technology, the variety of PCBs is increasing, placing increasing demands on the output and adaptability of reflow soldering ovens. This necessitates that the reflow soldering oven's conveyor system simultaneously meet the requirements for vibration resistance, high output, and adaptability to a wide range of PCB specifications.

The present invention achieves flexible control of different temperature zones by making the fixed mesh belt assembly, the feed mesh belt assembly, and the discharge mesh belt assembly independent of each other, facilitating adaptive fine-tuning without requiring replacement of the mesh belt, thus significantly saving costs and resolving the problem in the prior art of not having the function of flexible control for different temperature zones. When the user increases or decreases the temperature zone, or adjusts the length of the cooling zone, the conveyor belt needs to be replaced as a whole, resulting in high replacement costs.

[0020] Furthermore, a servo motor 10 is installed on one side of the fixed machine 12, and the output end of the servo motor 10 is connected to the screw body 3 through a rotating shaft. The screw body 3 is connected to the surface of the fixed machine 12 through a screw fixing mechanism 1. By turning on the servo motor 10, it is used to drive and control the screw body 3 for transmission. The surface of the screw body 3 is connected to the bottom end of the mesh belt transport platform 7 through a screw slider, thereby driving and controlling the mesh belt transport platform 7 to slide horizontally along the surface of the screw body 3, which is convenient for lateral horizontal transport adjustment of the mesh belt transport platform 7.
[0021] Furthermore, the first clamping cylinder 4, the second clamping cylinder 5 and the third clamping cylinder 8, the fourth clamping cylinder 9 are symmetrically distributed in pairs, and the output ends of the first clamping cylinder 4, the second clamping cylinder 5, the third clamping cylinder 8 and the fourth clamping cylinder 9 are all provided with clamping telescopic rods 6.

[0022] Furthermore, limit baffles 13 are provided on both sides of the mesh belt transport platform 7 , and the limit baffles 13 are fixed to the first slider 14 and the second slider 15 by welding. The limit baffles 13 are used to limit and support the two ends of the mesh belt transport platform 7 .
[0023] Furthermore, the mesh belt transport platform 7 slides horizontally along the surfaces of the first guide rail 2 and the second guide rail 11 , which makes the mesh belt transport platform 7 more stable during operation and improves the safety and stability of the mesh belt transport platform 7 during transportation.
