Description

technical field [0001] The invention relates to a power mechanism, in particular to a high-speed rib cutting machine power mechanism. Background technique [0002] When semiconductor integrated circuits are mass-produced, each circuit is carried by a lead frame. After the circuit on the lead frame is finished with chips, wire bonding, plastic encapsulation, and electroplating, it is necessary to remove the place used for the production of wires to form each circuit pin as an independent individual without interfering with each other. To achieve this process, it must be used Automatic stepping die is completed. In addition, in order to cooperate with the automatic mold operation, the lead frame must be automatically fed, conveyed and received, so the automatic cutting system for semiconductor integrated circuits was born. The power mechanism part of the automatic bead cutting system for semiconductor integrated circuits plays a major role in the production efficiency of the...

Problems solved by technology

[0004] In a word, there is following shortcoming in this existing semiconductor integrated circuit trimming system power mechanism: vibration is big, stops suddenly because of dropping to mold dead point by fast, produces inertia sudden change; ); bulky, intricate structural layout, inconvenient for daily maintenance; low production capacity, due to the incoherence of structural actions, logical actions must be completed first, and then start the second; hydraulic oil leakage will cause product pollution; high energy consumption, The hydraulic device has many times of energy transfer due to large mechanical loss

[0005] In addition, the power mechanism of the traditional rib cutting machine uses a 3-phase 380V motor as the power input, which drives the flywheel to rotate through the belt, and then drives the crankshaft to move. The pressure device pushes the power transmission rod to move up and down. It is necessary to increase the hydraulic pressure booster pump, high-pressure oil pipe, and oil storage tank, which cannot achieve precise control, and is prone to oil leakage, such as circuit obstacles. Accident; the traditional rib cutting machine is mostly driven by a belt, which is a vulnerable part and requires long-term maintenance; the traditional rib cutting machine is driven by a 380V motor, because the belt cannot withstand high-speed continuous operation for a long time, so the speed is slow and the production efficiency is low (per 50 die cuts per minute)
