The utility model provides a general fixing clamp for micro-
assembly substrate bonding, which comprises a base, a mounting mechanism, a plurality of pressing mechanisms and a
locking mechanism, and is characterized in that the top of the base is provided with a horizontally arranged fixing surface; the mounting mechanism is detachably arranged on the base, the mounting mechanism is provided with a mounting plate, the mounting plate is provided with a plurality of mounting holes perpendicular to the fixing surface, the mounting plate and the base are arranged at intervals, a gap between the base and the mounting plate is a fixing cavity, and the aligned to-be-fixed
assembly is arranged in the fixing cavity; the pressing mechanism is arranged in the mounting hole in a sliding mode, a protection part is arranged at the bottom of the pressing mechanism, and the pressing mechanism can make the protection part abut against the top of the to-be-fixed
assembly or release abutting connection with the to-be-fixed assembly due to sliding; the
locking mechanism is arranged between the pressing mechanism and the mounting plate, and when the
locking mechanism is locked, the pressing mechanism and the mounting plate are relatively fixed. According to the utility model, the base is detachably connected with the mounting mechanism, so that the structure is conveniently and quickly replaced or adjusted, different production requirements are met, the equipment switching cost is reduced, and the bonding efficiency of a micro-assembly substrate
bonding process is improved.
