A kind of patch plug construction of electronic component
Technical field
The present invention relates to the patches of the electronic component on pcb board to insert apparatus field, and in particular to electronic component patch is inserted
The placement head and plug head of equipment.
Background technique
Patch machine equipment belongs to one of SMT (Surface Mount System surface mount system) chip mounter, with
The development of electronic technology, traditional SMT chip mounter have been unable to meet industry production demand, chip mounter just comes into being at this time.
As automatic technology constantly improves, the degree of automation of chip mounter is also constantly improved, existing full-automatic
Chip mounter can be realized automatic charging movement, automatic chip mounting movement and automatic blanking movement, and the degree of automation is very high and work
It is also very high to make efficiency.
During material is mounted on substrate using full-automatic chip mounter, substrate is filled with the automatic conveying of chip mounter
Set and be delivered to designated position, after base plate transfer in place after, mounting head passes through suction nozzle absorbing material and material is mounted on substrate
Surface.
The movement of suction, patch material in existing mounting head is to drive Liang Zu operating mechanism by two groups of different drive modules
It moves respectively, structure is complex, and needs that processing equipment is cooperateed with to cooperate with the working condition of two groups of drive modules.Though
So, also have and synchronously driven mounting head realized to Liang Zu operating mechanism using single drive module, but its structure is still complex,
There is certain deficiency in manufacturing cost, functional reliability, stability, is not well positioned to meet patch industrialized production
It needs.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, provide that a kind of structure is simple, functional reliability
The mounting head of high sealed in unit.
To achieve the above object, the technical scheme adopted by the invention is that:
A kind of patch plug construction of electronic component, including substrate, driving unit, transmission mechanism, adsorption mechanism, patch material machine
Structure;
Driving unit is installed on the mounting plate that one piece is connected with substrate;
Transmission mechanism is installed on substrate by shaft;
Transmission mechanism includes the driving wheel and two Special-shaped cams of one with driving unit cooperation;
Adsorption mechanism is realized with a Special-shaped cam and is cooperated by being installed on substrate;
Tie Liao mechanism realizes with a Special-shaped cam and cooperates by being installed on substrate.
Further, driving unit is driving motor, connect cooperation by belt between driving wheel.
Further, adsorption mechanism includes fixed plate, cylinder, suction head, guide rod, and guide rod passes through guide rail and reset spring
It is installed on substrate, and is provided at one end with a Special-shaped cam against cooperation by block, guide rod is connected with fixed plate, cylinder peace
In fixed plate, fixed plate connect suction head with guide rod and is installed on cylinder movable axis, drives suction head to make via cylinder past
Linear motion.
Further, Tie Liao mechanism includes fixing seat, movable block, patch material head, oscillating rod, and fixing seat is mounted on substrate
On, movable block is mounted in fixing seat by guide rail and reset spring, and patch material head is mounted on movable block, and the axis of oscillating rod is logical
It crosses through axle sleeve installation on the base, realizes that oscillating rod is rotated freely along axis, oscillating rod one end is connected with movable block, the other end
On be provided with a Special-shaped cam against cooperation by block.
Further, feed well is additionally provided in Tie Liao mechanism.
When the present invention is implemented, driving wheel is driven to rotate using driving unit, driving wheel drives two Special-shaped cams synchronous in turn
Rotation, due to leaning on block and Special-shaped cam against in turn, due to the shape external structure of Special-shaped cam, promotion is leaned on guide rod, oscillating rod
Block movement, and then oscillating rod swing and guide rod synchronization telescope are driven, realize the processing of suction, patch material.
The configuration of the present invention is simple, design rationally, by single driving unit realize synchronous driving to two mechanisms, meanwhile, by
Simple in structure, so that manufacturing cost is lower, functional reliability is good, can effectively reduce the whole complicated process of chip mounter, improves
Working efficiency.
