Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead repair technology, specifically a flat heating device for repairing small-pitch LED lamp beads. Background Technology

[0002] Fine-pitch LED beads refer to LED beads with extremely small spacing, typically less than 2.5 mm, and often referring to LEDs with a spacing of less than 2 mm. During the repair of fine-pitch LED beads, technicians need to heat the LED beads to a certain temperature to safely remove the damaged beads and solder on the new ones. Therefore, a planar heating device for repairing fine-pitch LED beads is needed. However, current planar heating devices still have the following shortcomings:

[0003] For example, patent document CN217096051U discloses a laser rework heating device for LED chips. This LED chip laser rework heating device adopts two preheating methods, one above and one below, which helps to reduce the temperature difference between the chip and the substrate, improve the reliability of product rework, and offers flexible selection and high versatility. However, it is not easy to cool down after a new LED chip is soldered on, which can easily lead to a decrease in repair efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a small-pitch LED bead repair planar heating device. Utility Model Content

[0023] The specific operation is as follows: During use, the movable frame 302 slides upward through the sliding connection between the inner side of the movable frame 302 and the surface of the fixed plate 301. This causes the movable frame 302 to drive the cooling chamber 305 to move upward, keeping the air outlet 308 flush with the fixed support plate 6. At the same time, the fixed plate 301 and the fixed hole 303 on the surface of the movable frame 302 are aligned. The fixed plate 301 and the movable frame 302 are fixed by the threaded connection between the fixed bolt 304 and the inner side of the fixed hole 303. The air cooler 306 is started to allow cold air to enter the cooling chamber 305 and then exit through the air outlet 308 to cool the reinstalled LED beads.
