Abstract

A mechanical arm for an automatic welding fume tracking and collecting device comprises a fixed seat, a rotary seat, a driving arm, a driven arm, a rocker arm, a rotary motor, a rotary driving gear, a rotary driven gear, a movable arm motor, a movable arm driving gear, a movable arm driven gear, a suction port cover and a welding fume exhaust tube. The mechanical arm is simple in structure, only rotation of the two motors needs to be controlled, so that automatic welding fume tracking and collecting treatment can be realized within a circular area around the fixed seat, and the radius of the circular area is equal to the maximum extension distance of the tail end of the rocker arm.

Description

A kind ofly be used to weld the mechanical arm of cigarette from the motion tracking gathering-device

Technical field

The utility model relates to a kind of welding fume collecting device, particularly a kind ofly is used to weld the mechanical arm of cigarette from the motion tracking gathering-device.

Background technology

At present, the method that the butt welding cigarette carries out collection and treatment mainly contains two kinds: a kind of is to carry out whole exhausting in the weld job zone of workpiece, and smog is carried out collection and treatment; Though this method is simple to operate, the exhausting area is bigger, so whole exhausting amount is big; Energy consumption is high, and the smoke abatement effect is undesirable; Another kind is to adopt point-to-point mode, and the weldering cigarette that promptly produces for single pad carries out collection and treatment separately with a less suction opeing, and the exhausting amount that this method requires is little, has and uses advantages such as flexible, convenient, energy-conservation.But change place greatly for bigger welding work pieces or bond pad locations, its suction opeing must be able to be followed solder joint and moved.Existing in the market weldering cigarette is from the motion tracking gathering-device; But such weldering cigarette is from the mechanical arm complex structure of motion tracking gathering-device, and the number of motors of driving device arm is too much, also causes control too complicated; These all cause cost too high, and can't accurately following the tracks of of having puts in place.

Summary of the invention

In order to overcome the above problems, it is a kind of simple in structure that the utility model provides, and drive motors quantity is few, and equipment cost is low is used to weld the mechanical arm of cigarette from the motion tracking gathering-device.

In order to reach above-mentioned technical purpose, the technical scheme of the utility model is:

A kind ofly be used to weld the mechanical arm of cigarette from the motion tracking gathering-device; Comprise holder, rotating seat, master arm, slave arm, rocking arm, electric rotating machine, rotation driving gear, rotation driven gear, swing arm motor, swing arm driving gear, swing arm driven gear, breathing mask and weldering cigarette exhaust column; Said rotation driven gear is packed on the said holder with one heart; Said rotating seat is installed on the said holder through the sliding sleeve that is sleeved on the said holder; Electric rotating machine, swing arm motor, swing arm driven gear, slave arm and master arm are installed on the said rotating seat; Be fixed with rotation driving gear on the axle of said electric rotating machine with said rotation driven gear engagement; One end of said master arm and slave arm is hinged on the said rotating seat through hinge, and the other end of said master arm and slave arm joins through hinge and said rocking arm, and the end of said rocking arm is connected with the exhausting mouth mask; Said weldering cigarette exhaust column is installed on said master arm and the rocking arm; One end interface of said weldering cigarette exhaust column joins through the air inlet of holder with the weldering fume purifier, and other end interface and exhausting mouth mask join, and said swing arm driven gear is installed on the said rotating seat with the hinge of said master arm is concentric; Said master arm is fixed on the said swing arm driven gear, and said swing arm driving gear is packed on the said swing arm motor shaft and with said swing arm driven gear and meshes.

Owing to adopt said structure; This device is as long as the rotation of two motors of control just can realize with the holder being the center; With the tensible of the terminal institute of rocking arm to ultimate range be the weldering cigarette collection and treatment in the circular flat of radius; This device can also be installed on the portable weldering fume purifier, makes that its working range is wider, and realizes that the weldering cigarette is from the motion tracking collection and treatment.In sum, the utlity model has simple in structurely, advantage such as drive motors quantity is few, and equipment cost is low is fit to substitute the mechanical arm of existing weldering cigarette from the motion tracking gathering-device.

In the accompanying

drawing

1,2,3,1 holder, 2 rotation driving gears, 3 rotation driven gears, 4 rotating seats; 5 electric rotating machines, 6 swing arm driven gears, 7 master arms, 8. slave arm, 9 rocking arms; 10 weldering cigarette exhaust columns, 11 exhausting mouth masks, 12 swing arm motors, 13 swing arm driving gears, 14 sliding sleeves.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described further.

Referring to Fig. 1 to Fig. 3; This is used to weld cigarette and comprises holder 1, rotating seat 4, master arm 7, slave arm 8, rocking arm 9, electric rotating machine 5, rotation driving gear 2, rotation driven gear 3, swing arm motor 12, swing arm driving gear 13, swing arm driven gear 6, exhausting mouth mask 11 and weldering cigarette exhaust column 10 from the mechanical arm embodiment of motion tracking gathering-device, and holder 1 docks with the air inlet of weldering fume purifier and be fixing; Rotation driven gear 3 is packed on the holder 1 and is concentric with holder 1; Rotating seat 4 is sleeved on the holder 1 through a sliding sleeve 14, and can be around the 360 ° of rotations in holder 1 center, and rotation driving gear 2 is packed in 5 of electric rotating machines and upward and with electric rotating machine 5 one lifting devices on rotating seat 4 and with rotation driven gear 3, meshes; Master arm 7 all passes through hinge means on rotating seat 4 with slave arm 8, and the other end of master arm 7 and slave arm 8 also all joins through hinge and rocking arm 9; The end equipment of rocking arm 9 has exhausting mouth mask 11; Weldering cigarette exhaust column 10 devices are on master arm 7 and rocking arm 9, and the one of which end interface links to each other through the air inlet of holder 1 with the weldering fume purifier, and other end interface and exhausting mouth mask 11 join; Swing arm driven gear 6 is packed on the master arm 7 and is concentric with the hinge of master arm 7 devices on rotating seat 4; Swing arm driving gear 13 is packed in 12 in swing arm motor and upward and with swing arm motor 12 1 lifting devices on rotating seat 4 and with swing arm driven gear 6, meshes.

Use the utility model, control electric rotating machine 5 rotates, and rocking arm 9 is rotated in 360 ° scope around holder 1 with weldering cigarette exhaust column 10 and exhausting mouth mask 11; Control swing arm motor 12 rotates, can make rocking arm 9 with exhausting mouth mask 11 be starting point with holder 1 to 9 tensibles of rocking arm to the solstics be mobile in the straightway of terminal point.Control simultaneously electric rotating machine 5 and swing arm motor 12 rotate just can make rocking arm 9 be with exhausting mouth mask 11 accurately arrival be the center with holder 1, with the tensible of rocking arm 9 terminal institutes to ultimate range be the position, any point in the circular flat of radius.
