And it is fixedly connected with central axis 2 with jackscrew.In the present embodiment, the position by adjusting limited block 6 on central axis 2, can
To change stroke of the central axis 2 on center axis thereof direction indirectly, so that change suction nozzle 1 moves up and down distance.This
It is also the adjustment to 302 pressure of spring in adsorption-buffering mechanism 3.Such setting can guarantee that holding device is being coped with
Make when different sticking situation and in time adjusting, guarantee the precision of sticking, will not because of suction nozzle shift length it is excessive or
It is too small to cause sticking inaccurate or shakiness.Device is reduced during carrying camera lens, is damaged caused by camera lens, is improved
The delivery quality of camera lens and the qualification rate of camera lens.
A kind of embodiment according to the present invention, the method using holding device adjustment angle lens of the invention are as follows:
Belt wheel 505 in rotary drive mechanism 5 being connected with power source, being revolved with will pass through power source band movable belt pulley 505
Turn.The rotation of belt wheel 505 can drive rotary drive mechanism to be rotated.Because belt wheel mounting base 504 and belt wheel 505 are solid with jackscrew
Fixed connection, flange 503 are bolted with belt wheel mounting base 504, and axle sleeve 502 and flange 503 are interference fit, therefore work as belt wheel
When 505 rotation, band movable belt pulley mounting base 504, flange 503 and axle sleeve 502 therewith coaxial rotating Vortex.Axle sleeve 502 is in
Mandrel 2 is keyed, and when coaxial synchronous rotary under drive of the axle sleeve 502 in belt wheel 505, passes through axle sleeve 502 and central axis 2
Mutually matched key connection, i.e. drive central axis 2 and 505 synchronous rotary of belt wheel.Central axis 2 is to be slidably matched with mounting base 4, when
When central axis 2 rotates under the drive of rotary drive mechanism 5 across mounting base 4, the not synchronous rotation of mounting base 4.Absorption is slow
Punch mechanism 3 is to be threadedly coupled with central axis 2, then drives the synchronous rotation of adsorption-buffering mechanism 3 when central axis 2 rotates, real
Now the central axis to the camera lens being adsorbed in adsorption-buffering mechanism 3 around central axis 2 rotates angle.
A kind of embodiment according to the present invention, the method using holding device compensator or trimmer pressure of the invention are as follows:
Holding device is controlled, contacts suction nozzle 1 with to sticking camera lens, is ready for sticking carrying.When suction nozzle 1 connects with camera lens
Certain pressure can be generated when touching, camera lens can generate a buffer brake to suction nozzle 1, which can pass to suction by suction nozzle 1
Attached buffer gear 3, adsorption-buffering mechanism 3 will push central axis 2 and axially move upwards to unload this partial pressure.It inhales
When attached buffer gear 3 moves upwards, the second limit hole 403 into mounting base 4 is run, the second limit hole 403 blocks backstop
Part 303, the one end for making spring 302 be supported on stop part 303 no longer move upwards, and suction nozzle 1 and suction nozzle fixing seat 301 are in spring
Continue to move in 302 elastic range, and central axis 2 is then continued up across the intermediate throughholes 402 of mounting base 4.Center
Axis 2 is to be slidably matched with rotary drive mechanism 5, then central axis 2 passes through rotary drive mechanism 5, drives limited block 6 and transition connection
Part 7 therewith moves upwards, and can thus lay down pressure.When device move up to certain distance adjustment holding device and
Between camera lens when pressure, since the elastic force of spring 302 acts on, central axis 2 is made to start to move downward.Limited block 6 and the top of central axis 2
Silk is fixedly connected, and when central axis 2 drives limited block 6 to move to rotary drive mechanism 5, limited block 6 is driven in rotation the card of mechanism 5
Firmly, then central axis 2 does not continue to move still further below.Holding device adjusts central axis 2 in axial side by spring 302 and limited block 6
It moves up and down to buffer the pressure between holding device and camera lens.
Above content is that a specific embodiment of the invention enumerates, for the equipment and structure of wherein not detailed description,
Should be understood as that the existing common apparatus in this field and universal method is taken to be practiced.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
