A kind of Multi Role Aircraft loader charging tray grasping mechanism
Technical field
The present invention relates to chip mounter field of mechanical technique, particularly relate to the loader of a kind of multifunctional patch machine.
Background technology
Chip mounter is that surface mount elements is placed into the equipment on wiring board relevant position.Affecting a lot of because have of multifunctional patch machine production efficiency, the feeding machanism of multifunctional patch machine is exactly the factor that one of them is important.At present, when being left out feeding question, the paster head of chip mounter can carry out paster operation at short notice rapidly and accurately, and this just requires that the loader of chip mounter wants uninterrupted to paster head feed rapidly.
Along with electronic technology develops, wiring board is increasingly sophisticated, often needs to paste simultaneously or weld the surface mount elements of multiple different size and model on one piece of wiring board.The sizes and types of surface mount elements are different, and it stores and assembling mode is also not quite similar.Typically small surface mount elements is many to be stored with tape package packaged.The loader of these surface mount elements is generally adopted the form that storing roller, hold-down roller and conveyer device combine, wherein, storing roller is coiled to form by storing band, and the surface mount elements on storing band can be taken off by hold-down roller, and surface mount elements is flowed to paster suction nozzle by conveyer device.This storing roller can store substantial amounts of surface mount elements, only need to change storing roller in time when storing roller is used up, thus achieve rapid and continual feed.And bigger surface mount elements is usually and stores with the packaged of pallet, this packaged form takes up room relatively big, when to chip mounter suction nozzle feed, is difficult to accomplish rapid and continual feed.
For bigger surface mount elements, in order to realize continual feed, the structure of loader is most important.Generally, loader includes structure for conveying and captures structure, and structure for conveying for being transported to the position specified by charging tray, and capturing structure is for capturing and fixing charging tray.Wherein, capture structure can capture accurately and rapidly and fixing charging tray can affect the production efficiency of loader.As can be seen here, in multifunctional patch machine technology field, simple in construction, and the loader crawl structure of charging tray can be captured quickly and accurately, the production efficiency to raising chip mounter is very important, when particularly in the surface mount elements that attachment is bigger.The present invention provides a kind of multifunctional patch machine loader charging tray grasping mechanism, and its simple in construction is with low cost, simple operation.
Summary of the invention
In view of there is above-mentioned technical problem in prior art, the present invention provides a kind of Multi Role Aircraft loader charging tray grasping mechanism.Described grasping mechanism simple in construction, with low cost, simple operation, it is possible to capture charging tray accurately and rapidly.The technical scheme that feeder of plaster machine charging tray grasping mechanism of the present invention adopts is as described below.
The present invention provides a kind of feeder of plaster machine charging tray grasping mechanism, and described grasping mechanism includes a pair jaw 1 and pedestal 2.Described jaw 1 includes slide block 3 and the alignment pin 4 being fixed on slide block 3 and sliding sleeve 5, described pedestal 2 is provided with 6, two guide pillars 7 of two jaw guide rails and two fastening springs 8,6, two guide pillars 7 of said two jaw guide rail and two fastening spring 8 head and the tail respectively be oppositely arranged.When described pedestal 2 and a pair jaw 1 combine, described slide block 3 matches with jaw guide rail 6, and described sliding sleeve 5 matches with guide pillar 7, and described fastening spring 8 is enclosed within guide pillar 7 and compresses so that a pair jaw 1 is close to each other or is separated from each other.
The relative motion that can be controlled a pair jaw 1 by cylinder 9 of described charging tray grasping mechanism, it is achieved the clamping of grasping mechanism and unclamping.
The charging tray 10 matched with described charging tray grasping mechanism is provided with charging tray and captures hole 11, location in corresponding position.
Described charging tray grasping mechanism can pass through pedestal 2 and be fixed on the conveying mechanism of loader, and described conveying mechanism can drive charging tray grasping mechanism to move.Described conveying mechanism includes slide rail 12, belt conveyor 13 and motor, and described charging tray grasping mechanism is fixed on belt conveyor by pedestal 2, and can move along slide rail 12 under the drive of motor.
The work process below feeder of plaster machine charging tray of the present invention captured is specifically described.
Described charging tray grasping mechanism is fixed on the belt conveyor 13 of loader conveying mechanism, and slide rail 12 along conveying mechanism can move under the drive of motor.Described charging tray 10 is placed on the temporary place 14 of charging tray, and charging tray 10 is provided with charging tray and captures hole 11, location in corresponding position.
When charging tray grasping mechanism works, loader conveying mechanism starts driven by motor belt conveyor 13 and moves, and described charging tray grasping mechanism moves to the temporary place 14 of charging tray under the drive of belt conveyor 13.Before moving to charging tray crawl position, cylinder 9 controls jaw 1 and moves, and compresses fastening spring 8 further.When moving to charging tray crawl position, it is corresponding that the alignment pin 4 of jaw 1 captures hole 11, location with the charging tray of charging tray 10, and motor stops, cylinder 9 resets, and now, fastening spring 8 drives jaw action, make alignment pin 4 insert charging tray and capture hole 11, location, thus completing to capture the operation of charging tray 10.
After capturing charging tray 10, motor adverse movement, drive charging tray grasping mechanism and charging tray 10 to move to pre-feed position.After feed terminates, driven by motor charging tray 10 returns to the temporary place 14 of charging tray, and charging tray 10 is delivered to original place, controls jaw 1 by cylinder 9 and moves, compresses fastening spring 8, makes alignment pin 4 capture hole 11, location from the charging tray of charging tray 10 and departs from.Then, under the drive of conveying mechanism, charging tray grasping mechanism is moved the operation carrying out capturing charging tray to next charging tray place, and is delivered to pre-feed position.So circulate this process, it is achieved continual feed.
Feeder of plaster machine charging tray grasping mechanism of the present invention has the advantages that.
1, described loader charging tray grasping mechanism simple in construction, with low cost, simple operation;
2, described loader charging tray grasping mechanism is capable of precise positioning, automatically captures charging tray;
3, described loader charging tray grasping mechanism achieves uninterrupted feed.
