AI Technical Summary
The heating element of the existing die bonder has a complicated electrical connection structure when rotating, which is prone to wire tangling, increases weight and difficulty in rotation control, occupies space and poses a risk of wire breakage.
An electrical connection structure using conductive rings and conductive strips is adopted. By setting several conductive rings on the first circuit board and setting corresponding conductive strips and installing spring contacts on the second circuit board, stable conductivity is ensured during rotation, avoiding wire entanglement and breakage.
The simplified nozzle structure improves the stability and durability of the electrical connection, reduces space occupation, enhances the stability of conductivity and the durability of the spring, and reduces the risk of vibration during rotation.
