Summary of the invention
The shortcomings that overcome both the above mainstream minute hand structure, the present invention discloses a kind of sample loading gun minute hand transmission mechanism, is
Sample loading gun provide move up and down and sample loading gun between the mobile power support in position, solve transmission accuracy, noise, failure rate, at
This problems such as.
To realize the purpose, the technical solution adopted by the present invention is that:
A kind of sample loading gun minute hand transmission mechanism, including minute hand plate, the fixed linear guide of one side of the minute hand plate, with the straight line
Guide rail is slidably matched sliding block, with the affixed more than two sample loading gun needle unit framves of the sliding block, it is characterised in that: at described point
The another side of needle plate, which is pivoted, passes through stepper motor with the consistent teeth-free guide rod of the linear guide direction of motion, the teeth-free guide rod
Drive forward or reverse, opened up on the minute hand plate it is long to the axial consistent slotted hole of the teeth-free guide rod, the anodontia
Guide rod has and sample loading gun needle unit frame anodontia nut equal in number, the fixed company in the inside of each anodontia nut
Bar, each connecting rod pass through an affixed sample loading gun needle unit frame after the slotted hole.
Further, fixed vertical plate is distinguished at the both ends of the minute hand plate another side, and the optical axis is pivoted by bearing
On the vertical plate, one end of the optical axis passes through fixed synchronous pulley A after the vertical plate, same with the synchronous pulley A
The motor shaft of the fixed stepper motor in the inside of the vertical plate of side, the stepper motor is solid after the vertical plate of the side
If winding synchronous belt on synchronous pulley a B, the synchronous pulley A and synchronous pulley B.
Further, the screw pitch of the anodontia nut is different.
Teeth-free guide rod is also no spiral shell guide rod, anodontia screw rod, and anodontia polished rod matches, teeth-free guide rod with anodontia nut
Rotation input, frictional drive drive anodontia nut move along a straight line and be accurately positioned on teeth-free guide rod.Compared with lead screw, tool
Have: 1. without clearance, low noise；2. high transmission efficiency, low running loss；3. safety, nut can skid automatically when excess load does not damage
And other elements；4. high-seal, dust-proof feature.
Compared with prior art, the present invention has a characteristic that
1. carry out minute hand transmission using teeth-free guide rod/anodontia nut structure has compared to the kind of drive of conventional cam structure
The characteristics of high transmission accuracy, speed is fast, low noise.It is possible to prevente effectively from backhaul gap
2. on the one hand reducing movement mechanism transverse width using teeth-free guide rod/anodontia nut structure, increase loading device sample-adding
Flexibility reduces equipment volume, and still further aspect can increase the transmission accuracy of movement mechanism, reduces failure rate.

Specific embodiment
Embodiment 1, attached drawing 5 are a kind of schematic diagrames of the full-automatic sample loading gun in eight channels, the mirror image contraposition installation in rack 100
The sample loading gun in two sets of four-ways totally eight channels,
Referring to Fig. 1-4, every set four-way sample loading gun minute hand transmission mechanism, including minute hand plate 1, the one side fixed 4 of the minute hand plate 1
Road linear guide 2 is slidably matched two sliding blocks 3 with the linear guide 2, the sliding block 3 of two of alternate one of linear guide
Affixed sample loading gun needle unit frame 4, amount to 4 needle unit framves 4, the another side of the minute hand plate 1 be pivoted with it is described
The consistent teeth-free guide rod 5 of 2 direction of motion of linear guide, the teeth-free guide rod 5 pass through the drive of stepper motor 6 forward or reverse,
It is opened up on the minute hand plate 1 long to axially consistent slotted hole 11, the teeth-free guide rod 5 have 4 nothings with the teeth-free guide rod 5
Tooth nut 6, the fixed connecting rod 7 in the inside of each anodontia nut 6, after each connecting rod 7 passes through the slotted hole 11
