Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is made a detailed explanation.
Fig. 1,2,3,4 be for silicon wafer production line silicon chip bin transmit thread replacing mechanism not
With the view of angle, its effect is to transport silicon between high-order transmission line 1 and low level transmission line 2
Sheet bin, this silicon chip bin transmission thread replacing mechanism includes two actuating mechanisms, and one is used to carry
The hoisting mechanism risen, one is used to the transmission mechanism transmitted.
In Fig. 3, one end of horizontal support plate 3 is fixing with the first riser 4 to be connected, horizontal support plate 3
The other end and the second riser 5 is fixing connects, the first riser 4 is provided with the first driven pulley and the
Two driven pulleys;Second riser is provided with the 3rd driven pulley 403 and the 4th driven pulley 404;
For transmission mechanism, the output shaft of transmission motor 6 and the input of transmission reductor 7
Axle is connected, and the output shaft of transmission reductor 7 is connected with the first drivewheel 8 and the second drivewheel 9,
Flat key can be used between it to connect, and such as two drivewheels are all set in the defeated of transmission reductor 7
On shaft, transmission motor 6 the first drivewheel 8 and the second drivewheel 9 is driven to rotate.Actively
A back-up ring can also be increased to prevent axial float outside wheel.
First conveyer belt 10 is around being located at the first drivewheel the 8, first driven pulley and the second driven pulley
On;The preferably position of three forms a triangle, and the triangle formed at the first conveyer belt
It is additionally provided with the first regulating wheel in the middle of the path of shape, is used for adjusting the tensile force of the first conveyer belt 10,
Additionally can also increase regulating wheel cornerite.Second conveyer belt 11 around be located at the second drivewheel 9,
On three driven pulleys 403 and the 4th driven pulley 404, similar, be also the position of preferred three also
Form a triangle, in the middle of it, also can be provided with the second regulating wheel 406.
During said structure action, transmission motor 6 drives transmission reductor 7, and then drives first
Drivewheel 8 and the second drivewheel 9 rotate, and drivewheel and driven pulley coordinate, the first conveyer belt
10 and second conveyer belt 11 run, drive above silicon chip bin to carry forward.
For elevating mechanism, lifting drive parts can use cylinder 12 to head on conveyer
Structure knee-action, by the flexible realization of cylinder 12 high-order transmission line and low level transmission line it
Between move.
Transmission motor 6 and transmission reductor 7 are positioned at the first riser 4, horizontal support plate 3, second
Outside the space that riser 5 and cylinder 12 surround.It is to say, cylinder 12 is positioned at horizontal support plate
Space below 3, is a cubical space in Fig. 3, but transmission motor 6 is not placed on this
In individual narrow space, such as, it is placed on transmission motor 6 and transmission reductor 7 is positioned at the first riser
The side not being connected with horizontal support plate 3 of 4, it is simply that the position in Fig. 1.The benefit of do so
It is to be not take up longitudinal space, i.e. saves bottom space, make product be also suitable for longitudinal space more
Thread-changing transmission on compact transmission line;
During operation,
Step 1, is sent to silicon chip bin by silicon chip bin on low level transmission line 2 by conveyer belt
On first conveyer belt 10 of transmission thread replacing mechanism and the second conveyer belt 11;Such as by silicon chip bin
14 are sent on the first conveyer belt 10 and the second conveyer belt 11.
Step 2, starts cylinder 12, and conveyer belt and silicon chip bin thereon are promoted to high-order biography
The height of defeated line 1;
Step 3, starts transmission motor 6, and the first conveyer belt 10 and the second conveyer belt 11 are by position
Silicon chip bin thereon is transferred to high-order transmission line 1;Can be by the biography of high-order transmission line during transmission
Send the speed of service of band identical with the speed holding of the conveyer belt of the present invention.
Step 4, starts cylinder 12, the first conveyer belt 10 and the second conveyer belt 11 is landed back
The height of low level transmission line 2.
So far, complete and silicon chip bin be transferred to high-order transmission line 1 from low level transmission line 2,
Again return to low level transmission line and take the process of other workpiece.
Further, the first riser 4 is additionally provided with the guide plate 13 for backgauge, guide plate
The height of 13 is higher than the height of the work surface of the first conveyer belt 10.So when to the first conveyer belt
When pushing silicon chip bin on 10, silicon chip bin can be directed to plate 13 to be stopped, is parked in the first biography
Send on band 10 and the second conveyer belt 11.Certainly, configuration inductive transducer utilizes detection of electrons also
It is possible.Need exist for illustrating a bit, push to silicon chip bin side and correspondence can arrange one again
Block guides guide plate, before pushing silicon chip bin, guides guide plate low on the first conveyer belt 10
In the height at the silicon chip bin place pushed through, guide the height of guide plate less than low level in other words
The height of transmission line, thus may insure that transmitting the silicon chip bin come can transmit smoothly and fall
On a moving belt.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, relevant
The those of ordinary skill of technical field, without departing from the spirit and scope of the present invention,
Can also make a variety of changes and modification, the technical scheme of the most all equivalents falls within the present invention
Category, the scope of patent protection of the present invention should be defined by the claims.
