The silicon substrate of a solar cell is generally a square silicon wafer. The brief flow of the silicon wafer fabrication is: the Czochralski method is used for producing the silicon single crystal rod, the crystal rod is rolled to form a cylindrical crystal rod, the cutting is carried out by adopting linear cutting, and after the crystal rod is cut to form a quasi-square or quasi-polygonal crystal rod, the edge skin material with the shape of an arched cylinder shown in figure 1 can be produced. The side skin material 1 is provided with a side wall arc surface 11 and a side wall plane 12, the side wall arc surface 11 corresponds to a cylindrical surface of the cylindrical crystal bar, and the side wall plane 12 corresponds to a cutting surface of the cylindrical crystal bar. In order to improve the utilization rate of raw materials, the flaw-piece 1 needs to be recycled.

The edge leather material 1 is crushed by manual crushing through tools such as a hammer and a hammer head, and the working strength of the crushing process is high based on the high hardness of the silicon material. In order to prevent the edge leather 1 from shaking during manual crushing, the side wall plane 12 of the edge leather 1 is generally downward, and the edge leather 1 is knocked and crushed towards the side wall arc surface 11. In addition, in the process of manually breaking the scrap leather 1 by an operator through a tool, impurities such as metal pollution are easily introduced into the scrap leather 1. Moreover, the flaw-piece material 1 has a side wall cambered surface 11, and the side wall cambered surface 11 makes the operating personnel be difficult to strike the point of wanting to the size of broken back silicon material is not well controlled, makes the artifical broken flaw-piece material 1 linear dimension of operating personnel not unified, produces easily and is not conform to the size of throwing the stove standard.

Therefore, for recycling the trim material 1, the improvement is needed including but not limited to: on the first hand, the broken silicon material of the edge skin material 1 is ensured to meet the linear size requirement of the furnace. In the second aspect, the mechanical automation degree of the edge leather material 1 crushing is improved, and the manual operation is reduced, so that the crushing efficiency is improved, and the labor intensity of personnel is reduced.

Fig. 2 illustrates a schematic structural diagram of an apparatus for breaking an edge skin material of a crystal bar provided by an embodiment of the present invention. As shown in fig. 2, the utility model provides a crystal bar limit cladding crushing equipment, include: the conveying mechanism 2 is used for conveying the edge leather 1, and the conveying mechanism 2 is in contact with the side wall cambered surface 11 of the edge leather 1. The clamping mechanism 3 is arranged above the conveying mechanism 2, the clamping mechanism 3 is provided with a clamping channel 31 extending to the tail end of the conveying mechanism 2, and the inner outline shape of the clamping channel 31 is matched with the outline shape of the edge leather 1. And the crushing mechanism 4 is positioned at the end part of the conveying mechanism 2 and is used for knocking the side wall plane 12 of the side leather 1 in cooperation with the conveying mechanism 2 and crushing the side leather 1 into a silicon material.

Fig. 3 is the schematic view of the broken principle of the flaw-piece in the embodiment of the present invention. For convenience of description, the working process of the conveying mechanism 2 for conveying the flaw-piece material 1 to the crushing mechanism 4 is defined as feeding, and the process of feeding the flaw-piece material 1 into the clamping channel 31 is defined as feeding.

As shown in fig. 3, when the flaw-piece 1 is loaded to the clamping mechanism 3, the clamping mechanism 3 can achieve a clamping effect, and then the flaw-piece 1 is crushed by the crushing mechanism 4 while being fed in a clamped state. For convenience of description, the length of the flaw-piece blank 1 conveyed to extend out of the clamping channel 31 to be crushed is defined as a, so that the linear dimension of the silicon material generated by crushing the flaw-piece blank 1 is theoretically uniform under the condition that the flaw-piece blank 1 is continuously fed in the crushing interval time of the crushing mechanism 4 and the feeding length is still A.

Based on the limit cladding 1 is bow-shaped main part, when the lateral wall cambered surface 11 of limit cladding 1 was up, crushing mechanism 4 was difficult to realize accurately knocking to the broken position that needs, led to the uncontrollable and easy unqualified size of the silicon material that produces. When the side wall cambered surface 11 of the edge leather 1 faces downwards, the edge leather 1 needs a matched structure in the clamping mechanism 3 to be stably loaded and crushed. The inner contour shape of the clamping channel 31 is matched with the contour shape of the edging material 1. The clamping mechanism 3 is used for clamping the boundary leather material 1 when the boundary leather material 1 is crushed, so that the boundary leather material 1 is kept continuously fed in the crushing process, and the boundary leather material 1 is limited in the clamping channel 31. It should be understood that the clamping channel 31 is not necessarily a channel structure with two ends communicating in the conventional sense, and the peripheral wall thereof may be integral or separate, sealed or partially hollowed. The clamping mechanism 3 ensures that the edge leather 1 is continuously fed by the conveying mechanism 2 in the axial direction and is limited to move in the circumferential direction.

The crushing speed of the crushing mechanism 4 is matched with the feeding speed of the conveying mechanism 2, the specific implementation mode of the crushing mechanism 4 is not limited, and the part of the edge leather 1 extending out of the clamping channel 31 can be crushed by a crushing unit or a crushing structure in the crushing mechanism 4.

In a practical production application scenario, an operator places the boundary leather 1 on the conveying mechanism 2, and the conveying mechanism 2 conveys the boundary leather 1 placed thereon in the conveying direction. Then the leather material 1 is conveyed by the conveying mechanism 2 to the front of the inlet of the clamping channel 31 and enters the clamping mechanism 3 through the clamping channel 31. Because the clamping channel 31 extends to the end part of the conveying mechanism 2, the edge leather 1 passes through the clamping channel 31 under the conveying action of the conveying mechanism 2, and the edge leather 1 gradually approaches the crushing mechanism 4 at the end part of the conveying mechanism 2 in the process of passing through the clamping channel 31. Under the conveying action of the conveying mechanism 2 and the clamping action of the clamping mechanism 3, the flaw-piece materials 1 gradually approach the crushing mechanism 4 and are crushed into silicon materials meeting the size requirement by the crushing mechanism 4.

Under the condition of adopting above-mentioned technical scheme, transport mechanism 2 will place the limit cladding 1 on it and convey to crushing mechanism 4, play autoloading's effect. Because the crushing mechanism 4 is positioned at the tail end of the conveying mechanism 2, the flaw-piece material 1 enters and gradually passes through the clamping channel 31 under the action of the conveying mechanism 2, and the automatic feeding effect is realized. Meanwhile, the boundary leather 1 gradually approaches the crushing mechanism 4 and is crushed by the crushing mechanism 4, the internal outline shape of the clamping channel 31 is matched with the outline shape of the boundary leather 1 in the crushing process, the boundary leather 1 in the clamping channel 31 is clamped and limited by the clamping mechanism 3, and the boundary leather 1 keeps stable feeding in the crushing process. Because crushing mechanism 4 and drive mechanism cooperation work, the speed of feed matches with the crushing speed phase of crushing mechanism 4, and crushing mechanism 4 strikes simultaneously with the lateral wall plane 12 of limit cladding 1, and broken contact position is controllable, and crushing precision improves, therefore the silicon material that the limit cladding 1 formed after being broken satisfies the dimensional requirement, improves the qualification rate of broken size. Based on this, the operation personnel only need place limit cladding 1 and can realize automatic broken limit cladding 1 to transport mechanism 2, and can satisfy the dimensional requirement of throwing the stove. Meanwhile, the crystal bar edge skin material crushing equipment can greatly reduce manual operation and reduce the labor intensity of operators.

Based on the description of the crystal bar flaw-piece crushing equipment in the above embodiments, in order to realize further improvement of mechanical automation, mechanical equipment is required to provide power for crushing and conveying, and the process of crushing and conveying is controlled.

The power unit 5 is connected with the transmission mechanism 2 and the crushing mechanism 4 directly or indirectly through a power unit or a transmission unit. The power mechanism 5 may be an independent mechanism, or may be a mechanism composed of power parts of the crushing mechanism 4 and the conveying mechanism 2.

The crystal bar edge leather crushing equipment also comprises a controller 6 electrically connected with the conveying mechanism 2 and the crushing mechanism 4, and the controller 6 controls the crushing speed of the crushing mechanism 4 to the leather 1 according to the conveying speed of the conveying mechanism 2. The controller 6 may be electrically connected to the power mechanism 5, and when the power mechanism 5 is an independent mechanism, the controller 6 is electrically connected to the power mechanism 5. When the power mechanism 5 is a mechanism consisting of the crushing mechanism 4 and the power part in the conveying mechanism 2, the controller 6 is electrically connected with the conveying mechanism 2 and the power part on the crushing mechanism 4 respectively. The controller 6 may be a single independent controller 6, or may be an integral control unit provided in the crushing mechanism 4, the conveying mechanism 2, and the power mechanism 5.

The control unit may be any existing control unit that can achieve the control effect, and is not limited to a specific form.

For example, the conveying mechanism 2 can comprise a conveying roller and a conveying belt arranged on the conveying roller, the power mechanism 5 is in power connection with the conveying roller, and the conveying roller drives the conveying belt to rotate, so that the edge leather 1 on the conveying belt is fed. The controller 6 controls the power output of the power mechanism 5 to the conveying mechanism 2 to realize the control of the conveying speed of the conveying belt.

For another example, the crushing mechanism 4 may comprise a crushing unit, and the controller 6 controls the crushing speed of the crushing unit by controlling the power output of the power mechanism 5 to the crushing mechanism 4. It should be understood that the crushing speed may or may not be constant.

Under the condition of adopting the technical scheme, the controller 6 is respectively and electrically connected with the conveying mechanism 2 and the crushing mechanism 4, so that the controller 6 can determine the given speed of the flaw-piece material 1 on the clamping channel 31 according to the conveying speed of the conveying mechanism 2. On this basis, the controller 6 can control the crushing mechanism 4 to crush the end part of the side cladding 1 extending out of the clamping channel 31 by referring to the given speed of the side cladding 1 on the clamping channel 31, so that the side cladding 1 is crushed into a silicon material meeting the size requirement to meet the recovery requirement.

In order to improve the crushing efficiency of limit cladding 1, the utility model provides a crystal bar limit cladding crushing equipment includes a plurality of clamping machine structure 3, and with this correspondence, has placed 1 pay-off simultaneously of a plurality of limit cladding on the transport mechanism 2.

In actual operation, the operator prevents the edge leather 1 from being spaced on the conveyor belt of the conveying mechanism 2, and the edge leather 1 is conveyed to the corresponding diversion channel 71 along with the conveyor belt. After passing through the diversion channel 71, the edge trim 1 is continuously conveyed to the clamping channel 31.

Under the condition of adopting the technical scheme, each shunting channel 71 is positioned at one end of the corresponding clamping mechanism 3 far away from the crushing mechanism 4, so that the shunting structure 7 is used for shunting the boundary leather materials 1 on the conveying mechanism 2 to the corresponding clamping mechanism 3 and conveying the boundary leather materials to pass through the clamping channels 31. Based on this, can utilize a plurality of clamping machine to construct 3 and crushing mechanism 4, carry out the breakage to a plurality of boundary leather materials 1 simultaneously, improve crushing efficiency. And, because reposition of redundant personnel structure 7 adopts the mode of reposition of redundant personnel passageway 71 to shunt side cladding 1, the side cladding 1 is gone into and is guided to corresponding clamping machine structure 3 behind the reposition of redundant personnel passageway 71, is broken by crushing mechanism 4 afterwards, consequently, utilizes reposition of redundant personnel structure 7 can reduce the risk of side cladding 1 at the stifled material of transport mechanism 2 to improve crushing efficiency.

As shown in fig. 6, in a possible implementation manner, the flow dividing structure 7 may include a plurality of flow guiding baffles 72, an area between each two adjacent flow guiding baffles 72 forms a flow dividing channel 71, and the two flow guiding baffles 72 may be shaped as a trapezoidal cylinder as shown in fig. 6, so that the size of the formed flow dividing channel 71 in the conveying direction of the conveying mechanism 2 becomes smaller.

When the width of the shunting channel 71 is gradually reduced, the leftwards and rightwards deviation of the edge leather 1 in the conveying process of the shunting channel 71 is not easy to occur, so that the edge leather 1 can be accurately conveyed into the clamping channel 31.

In the practical application example, the operator continuously puts the leather material 1 on the conveying mechanism 2, and the load of the conveying mechanism 2 is in a dynamic state. Meanwhile, the vibration or collision of the edge leather 1 in the placing process can influence the conveying effect of the conveying mechanism 2.

That is, the conveying component 22 is used for feeding the edge leather 1, and the stirring component 21 is used for feeding.

Under the condition of adopting the technical scheme, the conveying assembly 22 conveys the edge leather 1 to the corresponding flow dividing channel 71 and conveys the edge leather 1 to the shifting position of the shifting assembly 21. In this regard, the conveyor assembly 22 functions as a conveyor and as a diverter in cooperation with the deflector 72. When the offcut 1 is conveyed to the toggle assembly 21 by the conveying assembly 22, the offcut 1 is conveyed by the toggle assembly 21 and passes through the clamping channel 31. Based on this, the offcut 1 realizes the material loading at stirring subassembly 21, and offcut 1 can be stabilized and passed through clamping passageway 31 and is broken by crushing mechanism 4.

The shifting block 211 shifts the end surface of the side cladding 1 under the driving of the chain. Based on this, the offcut 1 can be stabilized through the clamping channel 31 under the action of the shifting block 211 and the chain.

As shown in fig. 7 and 8, in a possible implementation manner, each clamping mechanism 3 includes a feeding pad 32 located above the conveying mechanism 2, and a pressing assembly 33 located above the feeding pad 32, and the feeding pad 32 and the pressing assembly 33 form a clamping channel 31; the feeding pad plate 32 is provided with a first groove 321 matched with the side wall arc surface 11 of the side leather 1, the feeding pad plate 32 is used for supporting the side wall arc surface 11 of the side leather 1, and the pressing component 33 is used for pressing the side wall plane 12 of the side leather 1.

Based on the machining error, the thickness tolerance of the edge leather 1 is generally within 2mm, and the pressing component 33 can adjust the height of the contact part of the pressing component 33 and the edge leather 1 according to the thickness of the edge leather 1. For example, the pressing assembly 33 may be a self-adjusting pressing assembly 33, and the fixture 3 further includes a mounting plate 35 for limiting the pressing assembly 33, and the mounting plate 35 is used for limiting the lifting height range of the pressing assembly 33. When the edge leather 1 passes through the clamping channel 31, the edge leather 1 and the pressing assembly 33 are extruded, and the pressing assembly 33 is lifted under the limitation of the mounting plate 35. Based on the precision of crystal bar processing, the height difference of the cut flaw-piece 1 is within 2mm, and the self-adjusting pressing assembly 33 can realize the clamping effect.

Under the condition of adopting above-mentioned technical scheme, material loading backup pad 32 has the first recess 321 that matches with the lateral wall cambered surface 11 of limit cladding 1, realizes supporting the lateral wall cambered surface 11 of limit cladding 1 through first recess 321, compresses tightly subassembly 33 and exerts pressure to the lateral wall plane 12 of limit cladding 1, and limit cladding 1 falls on first recess 321 and can be stably exerted pressure by compressing tightly subassembly 33, and limit cladding 1 can remain stable by broken in-process. Meanwhile, when the edge leather 1 falls into the first groove 321 and the pressing assembly 33 is pressed, the side wall plane 12 of the edge leather 1 can tend to be horizontal, the edge leather 1 can be knocked by the knocking structures 41 of the crushing mechanism 4, and silicon materials generated by crushing the edge leather 1 have a regular shape, so that the crushing of the controllable size is realized.

As shown in fig. 8, in a possible implementation manner, the feeding pad plate 32 further has a second groove 322 located on the first groove 321, the second groove 322 penetrates through the surface of the feeding pad plate 32 close to the conveying mechanism 2, and the conveying mechanism 2 passes through the second groove 322 to contact the trim 1. The conveying mechanism 2 can comprise a shifting assembly 21 for feeding, a shifting block 211 in the shifting assembly 21 is used for shifting the end surface of the leather 1, and a second groove 322 is used for providing a yielding space for the movement of the shifting block 211. The tiny silicon slag generated by crushing is discharged from the second groove 322, so that the situation of material blockage is avoided.

Adopt under the condition of above-mentioned technical scheme, material loading backup pad 32 provides the space of stepping down for transport mechanism 2 through second recess 322, and transport mechanism 2 can pass second recess 322 and the contact of limit cladding 1, provides transmission power for the material loading of limit cladding 1.

As shown in fig. 7, in a possible implementation manner, the pressing assembly 33 includes a pressing plate 34 and a plurality of lifting rollers 33 distributed along the conveying direction of the conveying mechanism 2, and the pressing plate 34 is disposed at one lifting roller 33 of the plurality of lifting rollers 33 adjacent to the crushing mechanism 4.

Among the above-mentioned a plurality of lift rollers 33, three lift rollers 33 that contact limit cladding 1 earlier reduce in proper order apart from the height of transport mechanism 2, and limit cladding 1 is progressively compressed tightly, plays the effect that guide limit cladding 1 gets into clamping passageway 31. When the offcut 1 is fed to be close to the crushing mechanism 4, the pressing plate 34 presses the offcut 1. When the pressure strip 34 compresses tightly the boundary leather material 1, the pressure strip 34 can reduce the vibrations that the boundary leather material 1 produced during the breakage, and the atress is even when the one end that can make the boundary leather material 1 be close to crushing mechanism 4 is broken simultaneously, reduces the probability that the boundary leather material 1 takes place to shake and splits in length direction. Because the lifting roller 33 is provided with the rotating shaft 413, the lifting roller 33 and the edging 1 roll relatively in the feeding process of the edging 1, and therefore the lifting roller 33 does not generate extra resistance to the feeding of the edging 1.

With the above-described solution, the compacting plate 34 is adjacent to the crushing means 4. After the border cladding 1 is compressed tightly by the pressure strip 34, the pressure strip 34 can reduce the vibrations that the border cladding 1 produced when being broken to reduce the border cladding 1 and bring the shatter problem on length direction owing to vibrations, and then the size of the broken silicon material that produces of control border cladding 1 satisfies the recovery requirement. Meanwhile, in the process of pressing the edge leather 1, the edge leather 1 is gradually close to the crushing mechanism 4 under the conveying action of the conveying mechanism 2 through the lifting roller 33, and resistance is not generated by the lifting roller 33, so that the feeding speed of the edge leather 1 is controllable.

In one possible form of realization, as shown in fig. 9-11, each crushing means 4 comprises at least one set of rapping structures 41, each set of rapping structures 41 being located at the end of the chuck channel 31 that the respective chuck 3 has. The hardness of the part of each knocking structure 41, which is used for contacting the side leather 1, is greater than that of the side leather 1, and the direction of each knocking structure 41 for knocking the side leather 1 and the length direction of the corresponding side leather 1 form a preset included angle.

Each set of rapping structures 41 described above may have a plurality of rapping heads 411 (i.e. the crushing units described above) for point contact with the scrap 1. It should be understood that the point contact means that the contact portion of the knocking head 411 and the offcut 1 is small enough, and the specific contact area needs to be determined according to external factors such as machining. For example, the contact area is less than 1mm²Which may be understood as point contact.

The predetermined included angle may be 80-100. In practical applications, the arrangement direction of the knocking heads 411 is generally 90 ° to the length direction of the rim strip 1. When the knocking structure 41 breaks the trim 1, the possibility that the trim 1 is split in the longitudinal direction is the lowest. Each time the offcut 1 is broken by the knocking structure 41, it is equivalent to cutting a section along the cross section, and the interval of each cutting is consistent, so the linear dimension of the obtained silicon material after the offcut 1 is broken tends to be uniform.

In order to ensure that the silicon material is in a pollution-free state before being put into the furnace, the silicon material is ensured to meet the size requirement of the furnace after meeting the requirement. Therefore, the hardness of the part of each knocking structure 41 contacting the border material 1 is greater than that of the border material 1. For example, the portion of each knocking structure 41 for contacting the rim strip 1 is made of tungsten alloy such as tungsten-cobalt alloy or tungsten-steel alloy. Wherein the Mohs hardness of the crystalline silicon is the same, and the hardness of the tungsten cobalt alloy or the tungsten steel alloy is higher than that of the crystalline silicon. Meanwhile, the tungsten alloy is good in ductility and low in brittleness, so that metal fragments are not easily generated by the knocking structure 41 in the process of crushing the scrap leather 1 by the knocking structure 41, and metal pollution of the silicon material is prevented.

As can be seen from the above, since the hardness of the part of the knocking structure 41 contacting the edge leather 1 is greater than that of the edge leather 1, the knocking structure 41 itself is not easy to be broken (compared with the edge leather 1) in the process of breaking the edge leather 1, thereby avoiding the pollution to the edge leather 1.

Under the condition of adopting above-mentioned technical scheme, crushing mechanism 4 adopts and strikes structure 41, and the mode of point contact is strikeed can effectively break flaw-piece 1, and the contact of flaw-piece 1 and crushing mechanism 4 is minimum, reduces the pollution risk that crushing mechanism 4 brought. When the direction of knocking the edge leather 1 by the knocking structure 41 is perpendicular to the length direction of the corresponding edge leather 1, so that the edge leather 1 is broken, the probability of cracking along the length direction is reduced, and finally, the linear size of the silicon material generated after the edge leather 1 is broken is small, so that the recycling requirement is met. Meanwhile, the hardness of the part of the knocking structure 41, which is used for contacting the edge leather 1, is greater than that of the edge leather 1, so that the knocking structure 41 is not easy to break in the process of breaking the edge leather 1, and the pollution to the edge leather 1 is avoided.

In one possible implementation, as shown in fig. 9-11, each set of striking structures 41 includes a rotating shaft 413, a plurality of striking heads 411, and at least one multi-arm connector 412, each multi-arm connector 412 being disposed on the rotating shaft 413, each multi-arm connector 412 having a plurality of mounting ends, each striking head 411 being mounted on a respective mounting end.

The rotating shaft 413 is connected to the power mechanism 5, the power mechanism 5 drives the rotating shaft 413 to rotate, and the plurality of tapping heads 411 move circumferentially along the rotating shaft 413. When the edge skin material 1 is broken, the plurality of tapping heads 411 are simultaneously in point contact with the edge skin material 1.

The rotating shafts 413 among the multiple groups of knocking structures 41 in the crushing mechanism 4 can be the same rotating shaft 413, a plurality of multi-arm connectors 412 are arranged on the rotating shafts 413, and each multi-arm connector 412 is provided with a corresponding knocking head 411.

For example, as shown in fig. 9-11, each crushing mechanism 4 comprises four sets of tapping structures 41, and each set of tapping structures 41 comprises three tapping heads 411. Four sets of striking structures 41 are circumferentially arranged along the rotational axis 413. When the flaw-piece material 1 is crushed, the three knocking heads 411 are simultaneously in point contact with the flaw-piece material 1, and the connecting line of the three points is vertical to the length direction of the flaw-piece material 1.

Under the condition of adopting the technical scheme, the knocking head 411 is connected with the rotating shaft 413 through the multi-arm connecting piece 412, the knocking head 411 rotates along with the rotating shaft 413, periodic point contact with the edge leather 1 is realized, and therefore when the edge leather 1 is broken, the size of silicon materials generated by breaking tends to be uniform. Since the knocking head 411 is installed at the installation end of the multi-arm connector 412, the knocking head 411 can be disassembled and periodically replaced according to the service time, so as to ensure that the requirement of point contact between the knocking head 411 and the rim shell 1 is met.

In a possible implementation, as shown in fig. 12, the ingot-side material crushing device further comprises a collecting structure having at least one collecting channel 8 located below the crushing mechanism 4, and each collecting channel 8 is located at an end of the clamping channel 31 of the corresponding clamping mechanism 3.

Under the condition of adopting above-mentioned technical scheme, every collection channel 8 is located the tip of the clamping passageway 31 of corresponding clamping machine structure 3 and is located the below of crushing mechanism 4, and the silicon material that the broken production of boundary skin material 1 falls because of gravity, and the whereabouts gets into and through collection channel 8, during the corresponding collection equipment of collection channel 8 flow direction or collection mechanism subsequently, the operating personnel of being convenient for collect.

In a mode that probably realizes, the embodiment of the utility model provides a crystal bar flaw-piece material crushing equipment can also include collection mechanism, and during the structure was collected through collecting channel 8 entering to broken silicon chip, collection mechanism included shale shaker and a plurality of collecting vat.
