Double-end push broach and LED maintenance machine

Abstract

The invention discloses a double-head push broach and an LED maintenance machine, and relates to the field of semiconductor equipment and the technical field of machine manufacturing. The double-end push broach comprises a shell and a removing piece. A suction nozzle is arranged at the lower end part of the shell; an air passage connecting port is formed at one side of the shell; an accommodatingcavity is formed in the shell; the removing piece comprises a main body part and a removing part arranged at the lower end of the main body part; the main body part is arranged in the accommodating cavity, a first air passage is formed by the main body part and the cavity wall of the accommodating cavity, and the first air passage is communicated with the suction nozzle and the air passage connecting port; and the removing part is movably arranged at the suction nozzle. A vacuum generator is connected with the air passage connecting port, after the suction nozzle is aligned to a fault part ofa workpiece needing to be maintained, residues on the fault part are removed through the removing part, meanwhile, the vacuum generator works to enable the suction nozzle to absorb residual fragmentsand meanwhile absorb removed residues, and therefore the fault part is kept clean and tidy. Therefore, welding of new workpieces can be facilitated, maintenance operation is simplified, and the workpiece maintenance efficiency is improved.

Description

technical field [0001] The invention relates to the field of semiconductor equipment and the technical field of mechanical manufacturing, in particular to a double-headed push knife and an LED maintenance machine. Background technique [0002] Since the single size of the current Mini-LED is ≤200μm, and the density of Mini-LED components on the PCB is very high, an average of about 1,000 Mini-LEDs are laid out on each PCB; It is suitable for repairing on the current PCB, requiring skilled technicians to carefully remove the defective Mini-LEDs one by one with precise tweezers and shovels, and then use corresponding heating methods for secondary curing. However, taking the maintenance of 10 defective Mini-LEDs as an example, when using tweezers and shovels for maintenance, it is necessary to replace the shovels and tweezers frequently, to remove the Mini-LEDs and to clean up the residue after removal, and this process will take a long time. A skilled tradesman for at least 1...

[0002] Since the single size of the current Mini-LED is ≤200μm, and the density of Mini-LED components on the PCB is very high, an average of about 1,000 Mini-LEDs are laid out on each PCB; It is suitable for repairing on the current PCB, requiring skilled technicians to carefully remove the defective Mini-LEDs one by one with precise tweezers and shovels, and then use corresponding heating methods for secondary curing

However, taking the maintenance of 10 defective Mini-LEDs as an example, when using tweezers and shovels for maintenance, it is necessary to replace the shovels and tweezers frequently, to remove the Mini-LEDs and to clean up the residue after removal, and this process will take a long time. A skilled tradesman at least 1 hour

At the same time, as Mini-LED is about to be popularized and used faster and faster, it will be difficult for this repair process to fundamentally improve the repair efficiency
