A kind of switching mechanism
Technical field
The present invention relates to crystal silicon solar automatic system logistics transmission technical fields more particularly to one kind on the transmission line may be used
With by rack in the vertical switching mechanism overturn between transverse direction.
Background technology
With global greenhouse effect getting worse, oil, natural gas, the increasingly depleted of coal, environmental protection and energy saving have become generation
The theme of boundary's development.Solar energy as a kind of reserves are unlimited, cleaning, safety regenerative resource, be global new energy development
Direction.Under the guidance of national novel energy and regenerative resource industrial policy and the band of American-European solar energy market solid demand
Under dynamic, domestic solar photovoltaic industry rapid development in recent years.At present, China has become solar cell manufacture big country, possesses
The most manufacture of solar cells producer in the whole world and the production capacity of more than half.
The fast development of solar photovoltaic industry also promotes flourishing for domestic photovoltaic manufacturing equipment industry.
The early stage of solar cell industry development, solar battery sheet manufacturing enterprise do not generate automatic production line demand, production
Line is substantially to be slapped together by isolated semi-automatic, automation equipment.Increase with the explosion type of global solar photovoltaic industry
It is long, for, the solar battery sheet manufacturer meeting suitable with conventional power generation usage cost that be reduced to field of solar energy unit cost of electricity-generating
Increasingly an urgent demand uses highly integrated, supermatic production line.In future, the height of the degree of automation is in certain level
It will determine that who is only the minimum manufacturer of production cost, and by well-designed and high-efficiency operation automatic factory system
It can simply copy in subsequent factory, and get out of the red rapidly.The growth requirement of photovoltaic industry is complied with, it is external
Solar battery sheet production equipment is just from semi-automation to full-automation, intelligent transition, to improve production efficiency and product
Quality reduces production cost.
At present, the chip transmission between each technique unit of crystal silicon solar batteries slice assembly line is with stacking type or card slot type
Two ways loads silicon chip, is then manually carried using trolley.This mode efficiency is low, is unfavorable for mass producing.However, by
In the initial stage of crystal silicon solar batteries production line development there is no full-automatic production is considered, because being connect without possessing various automations
Mouthful, there is no each technique unit can be connected self-propagating material transmission system, also there is no adapt to this production
The automated handling method of process.
In order to realize full-automatic large-scale production, the chip transmission between each technique unit must use the automatic transmission to be
System is realized.For that purpose it is necessary to develop adapt to crystal silicon solar battery piece automatic production line rack magazine logistic transmission system.
Under this industry background, we have developed a series of logistics transmission modules, and logistic transmission system can be built according to customer demand, fast
Speed provides different production-scale crystal silicon solar batteries pieces and manufactures whole line automation solution.

It is simply introduced below in conjunction with the operation principle of switching mechanism of the attached drawing to being provided in above-described embodiment.
Fig. 9 to Figure 15 is refer to, Fig. 9 is the view that rack 100 reaches upturned position;Figure 10 is crawl rack
100 view;Figure 11 is the view of overturning rack 100;Figure 12, which is overturn for rack 100 to horizontal state, to be shown
It is intended to;Figure 13 is the view for placing rack 100;Figure 14 is the view that roll-over unit 2 resets;Figure 15 is overturning
Unit 2 is reset to schematic diagram during vertical position.
As shown in figure 9, B indicates rack direct of travel in figure, under original state, the Standard Cylinder of switching mechanism, second are slided
Desk-top cylinder 21 and parallel air gripper 24 are in contraction state, and the first sliding desk type cylinder 19 is in stretching state.When rack 100 is by passing
Defeated machine is transferred to flip bit, and 100 sensors in place of rack on conveyer detects signal, and conveyor is out of service at this time.
As shown in Figure 10, C indicates that parallel air gripper 24 opens in figure, and D indicates that the first sliding desk type cylinder 19 is shunk, E instructions the
Two sliding desk type cylinders 21 stretch out;First sliding desk type cylinder 19 of orthogonal motion unit 3 is shunk, and the second sliding desk type cylinder 21 stretches out,
So as to drive placement unit 4, close to rack 100, the parallel air gripper 24 of last placement unit 4 opens so that crawl finger 26 clamps
Rack 100.
As shown in Figure 11, Figure 12, F indicates that the first sliding desk type cylinder 19 stretches out in Figure 11, and G indicates that Standard Cylinder is stretched in Figure 12
Go out;First sliding desk type cylinder 19 of orthogonal motion unit 3 stretches out, and rack 100 is driven to leave conveyor, afterwards turns over unit 2
Standard Cylinder is stretched out.Orthogonal motion unit 3 and placement unit 4 is driven to overturn, until being detected close to switch on Standard Cylinder
Until cylinder is elongated to extreme position, so as to which the rack 100 on crawl finger 26 be driven to overturn to landscape positions.
As shown in figure 13, H indicates that parallel air gripper 24 is shunk in figure, and E indicates that the second sliding desk type cylinder 21 is shunk;Placement unit
Parallel air gripper 24 on 4 is shunk, and crawl finger 26 is driven to unclamp rack 100, so as to which rack 100 is placed on another conveyor
On, complete the overturning thread-changing campaign that rack 100 becomes traverse from placing vertically.
As shown in Figure 14, Figure 15, I indicates that Standard Cylinder is shunk in Figure 14, B instructions rack direct of travel in Figure 15;Overturning
The Standard Cylinder of unit 2 is contracted to initial position, while orthogonal motion unit 3 and placement unit 4 is driven to overturn.Crawl is single at this time
The position of member 4 becomes vertical, and so as to complete the reset of switching mechanism degree, mechanism may be reversed next rack 100, be placed on
Rack 100 on cross conveyor, according to demand can be two to transmission.
