There is one can be attracted spring card slot to the electromagnet of silicon wafer in fixed solar battery coating process.
Compared with prior art, the present invention in graphite boat piece ontology by being provided with several spring card slots, each bullet
One is correspondingly provided in spring card slot can fix spring card slot actuation the electromagnet of silicon wafer in solar battery coating process,
When artificial inserted sheet or machine inserted sheet, electromagnet is not powered, and spring card slot is opened, and biggish card slot space avoids silicon wafer and graphite boat
Friction between piece;After the completion of inserted sheet, electromagnet is powered, and silicon wafer is fixed in spring card slot contraction under the action of electromagnet suction
In graphite boat piece ontology, there is the advantages of surface for avoiding silicon wafer generates scratch, reduces the fraction defective of solar battery product.
As an improvement of the present invention, the graphite boat piece ontology is hollow structure.
As an improvement of the present invention, the spring card slot includes that two brackets and both ends are connect with the bracket respectively
Spring.
As an improvement of the present invention, the bracket is L-type.
As an improvement of the present invention, the electromagnet is located between two brackets.
As an improvement of the present invention, the spring is arranged in inside the hollow structure of the graphite boat piece ontology, institute
State the outside that bracket is partially located at the graphite boat piece ontology.
It is improved as another kind of the invention, length, width and the height of the bracket are 2 to 5 millimeters.
It is improved as another kind of the invention, the quantity of the electromagnet and the spring card slot is three.
The present invention also proposes a kind of graphite boat, including several solar battery coated graphite boat pieces above-mentioned, several
The solar battery coated graphite boat piece is evenly distributed in solar battery coated graphite boat.
Improved as another kind of the invention, the solar battery coated graphite boat piece with a thickness of 8-10 millimeters.

Positional relationship is merely for convenience of description of the present invention and simplification of the description, rather than the device or element of indication or suggestion meaning must
There must be specific orientation, be constructed and operated in a specific orientation, therefore be not considered as limiting the invention.In addition, art
Language " first ", " second " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicate institute
The quantity of the technical characteristic of instruction." first " is defined as a result, the feature of " second " can explicitly or implicitly include one
Or more this feature.In the description of the present invention, unless otherwise indicated, the meaning of " plurality " is two or more.
In addition, term " includes " and its any deformation, it is intended that cover and non-exclusive include.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected;It can
To be mechanical connection, it is also possible to be electrically connected;It can be directly connected, can also can be indirectly connected through an intermediary
Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
The invention will be further described with preferred embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of solar battery coated graphite boat piece, for loading silicon chip of solar cell, the graphite
Boat piece includes graphite boat piece ontology 1, several spring card slots 3, the spring card slot are provided in the graphite boat piece ontology 1
It is fixed for the silicon wafer in solar battery coating process.One is correspondingly provided in each spring card slot 3 to be attracted spring card slot 3
To the electromagnet 2 of silicon wafer in fixed solar battery coating process.Its working principles are as follows: in artificial inserted sheet or machine inserted sheet
When, electromagnet 2 is not powered, and spring card slot 3 is opened, and biggish card slot space avoids the friction between silicon wafer and graphite boat piece;It inserts
After the completion of piece, electromagnet 2 is powered, and spring card slot 3, which is shunk, under the action of 2 suction of electromagnet is fixed on graphite boat piece sheet for silicon wafer
In vivo, after the completion of filming process, electromagnet 2 powers off again, unloads lower silicon slice, completes the plated film of silicon wafer.With the surface for avoiding silicon wafer
The advantages of generating scratch, reducing the fraction defective of solar battery product.
Preferably, the graphite boat piece ontology 1 is hollow structure.
Preferably, the spring 31 that the spring card slot 3 is connect with the bracket 32 respectively including two brackets 32 and both ends,
The both ends of the i.e. described spring 31 are connect with the bracket 32 respectively.The effect of spring 31 is after electromagnet 2 is not powered or is powered
When powering off again, two brackets 32 are strutted, so that the distance between two brackets 32 is greater than silicon wafer width, to guarantee silicon chip surface
It generates scratch and is easy to take out silicon wafer.
Preferably, the bracket is L-type, and length, width and the height of the bracket are 2 to 5 millimeters, and above-mentioned size is set
Meter rationally, saves use space.
Preferably, the electromagnet 2 is located between two brackets 32, close to the spring 31, makes the electromagnet 2
Play maximum magneticaction.
Preferably, the spring 31 is arranged in inside the hollow structure of the graphite boat piece ontology 1,32 part of bracket
Positioned at the outside of the graphite boat piece ontology 1.The quantity of the electromagnet 2 and the spring card slot 31 is three.Structure ratio
It is relatively firm, reasonable quantity setting, manufacture easy to produce.
As shown in Fig. 2, a kind of solar battery coated graphite boat 4, including multiple solar battery coated graphite boat pieces 41,
The multiple solar battery coated graphite boat piece 41 is evenly distributed in solar battery coated graphite boat 4;Graphite boat piece 41
With a thickness of 8-10 millimeters,
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
