Description

Technical Field

[0001] The utility model relates to the technical field of LED crystal boats, in particular to an anti-deviating crystal boat conversion device. Background Art

[0002] As a new type of microelectronic device packaging material, semiconductor wafer boats have broad development space and prospects. At present, semiconductor wafer boats have been widely used in LED lighting, automotive lighting and other fields, becoming the mainstream material for LED packaging. Semiconductor wafer boats can improve the luminous efficiency and stability of LED lamps, and achieve longer life and higher brightness LED lamps.

[0003] At present, in the prior art, for example, a Chinese patent with a publication number of CN210156362U discloses a wafer boat conversion device, which uses a limit seat set on a bottom plate to allow a wafer boat loaded with wafers to be plugged into a pair of fixed limit seats and an empty wafer boat to be plugged into a limit seat that can move with a sliding plate, so that when the wafers on the wafer boat are converted, the limit seat limits the lateral movement of the wafer boat to prevent the wafer boat from shifting when the wafers are converted, and solves the problem that the existing wafer boat is prone to lateral shift when converting wafers, resulting in the wafer going off track when transferring to another wafer boat, resulting in the wafer being unable to be converted. However, the device needs to take both wafer boats out of the limit seats before the transfer of the next group can be carried out, resulting in its low working efficiency. In view of this, we propose an anti-shift wafer boat conversion device. Utility Model Content
