Description

Silicon rod squaring equipment, silicon rod squaring method and edge skin unloading device

Technical Field

The application relates to the technical field of crystalline silicon processing, in particular to silicon rod squaring equipment, a silicon rod squaring method and an edge skin unloading device.

Background

At present, with the importance and the opening of the society on the utilization of green renewable energy sources, the field of photovoltaic solar power generation is increasingly emphasized and developed. In the photovoltaic power generation field, a typical crystalline silicon solar cell is fabricated on a high quality silicon wafer which is cut from a pulled or cast silicon ingot by multi-wire saw.

The existing silicon wafer manufacturing process generally comprises the steps of firstly pulling a polycrystalline silicon brittle material into a silicon rod, and then adopting a squaring device to perform squaring; at the moment, the cutting mechanism feeds along the length direction of the silicon rod and cuts four planes which are parallel to each other in the circumferential direction of the silicon rod, so that the whole silicon rod is in a cuboid-like shape; and after the square is finished, slicing the square silicon rod along the length direction by adopting a multi-line slicing machine to obtain the required silicon wafer.

The existing squaring equipment can complete the structural design of the squaring cutting of a plurality of silicon rods at one time, but the existing silicon rod squaring equipment can complete the cutting of a plurality of silicon rods by feeding a cutting mechanism at one time, but because the number of the silicon rods is more, the cutting lines in the cutting mechanism need to pass through a plurality of wire guide wheels to turn when the wires are arranged, so that the cutting efficiency is reduced due to larger loss of the cutting lines during working, and the feeding speed of the cutting mechanism is usually slow in order to ensure the cutting effect, so that the overall cutting efficiency is not high in practice.

In addition, in the related silicon rod squaring operation, the silicon rod is subjected to squaring and cutting to form the edge skin, so that the formed edge skin is required to be unloaded firstly, and the common edge skin unloading mode is that an operator manually operates the edge skin to separate from the cut silicon rod and remove the edge skin from the silicon rod squaring equipment, so that the efficiency is low, and the risk of damaging the cut silicon rod is increased due to collision between the edge skin and the cut silicon rod in the carrying process.

In the related silicon rod squaring and cutting operation, the problems of low efficiency, edge skin unloading and the like of the silicon rod squaring and cutting operation exist. Therefore, it is necessary for those skilled in the art to disclose a silicon rod cutting device, a silicon rod cutting method and a side skin unloading device, so as to improve the cutting operation efficiency of the silicon rod cutting and the side skin unloading operation efficiency and reduce the overall cost of the silicon rod cutting.

It should be noted that the silicon rod squaring device and the silicon rod squaring method can be applied to the squaring cutting operation of the silicon rod.

Taking a single crystal silicon rod as an example, the forming process of the single crystal silicon rod may include: firstly, cutting an original long silicon rod by using a silicon rod cutting machine to form a plurality of sections of short silicon rods; after the cutting is completed, a silicon rod squarer is used for squaring the cut short silicon rod to form a monocrystalline silicon rod with a rectangular-like section. For example, patent publications such as CN105856445A, CN105946127a and CN105196433a may be cited as specific examples of a method for cutting an original long silicon rod to form a multi-stage short silicon rod using a silicon rod cutting machine, and patent publications such as CN105818285A may be cited as specific examples of a method for cutting a cut short silicon rod to form a single crystal silicon rod having a rectangular cross section using a silicon rod cutting machine. The process of forming the single crystal silicon rod is not limited to the foregoing technique, but in an alternative example, the process of forming the single crystal silicon rod may further include: firstly, using a full silicon rod squarer to square an original long silicon rod to form a long monocrystalline silicon rod with a rectangular cross section; after the square is finished, cutting the square long monocrystalline silicon rod by using a silicon rod cutting machine to form a short crystal silicon rod. Among them, a specific implementation method of forming a rectangular-like long single crystal silicon rod by using an all-silicon rod squarer to square an original long silicon rod is described in patent publication such as CN106003443 a.

Referring to fig. 1, a schematic structure of a silicon rod opening apparatus according to the present application is shown in a certain embodiment. As shown in the figure, the silicon rod squaring device disclosed by the application comprises: the device comprises a machine base 1, a silicon rod bearing device, a linear cutting device 3 and an edge skin unloading device. The silicon rod bearing device is arranged on the machine base 1 and is used for bearing the silicon rods 10 to be cut which are vertically placed. The wire cutting device 3 is arranged on the machine base 1 and is used for squaring and cutting the silicon rod 10 to be cut, which is carried by the silicon rod carrying device. The edge skin unloading device is arranged on the machine base 1 and is used for unloading the edge skin generated after the wire cutting device 3 performs squaring cutting.

The stand 1 is a main body part of a silicon rod squaring device. Preferably, the size and weight of the stand 1 are larger to provide a larger mounting surface and a more reliable overall stability.

The silicon rod bearing device is arranged on the machine base 1, and the machine base 1 is provided with a workbench 11. The silicon rod bearing device comprises a silicon rod bearing table 21 arranged on the workbench 11 and a silicon rod pushing mechanism 22 corresponding to the silicon rod bearing table 21.

The silicon rod carrying table 21 is used for carrying the silicon rods 10 to be cut which are vertically placed. In this embodiment, the silicon rod carrying table 21 has a mesa structure and is rested on the table 11. The silicon rod 10 to be cut is a silicon rod formed by pulling up a single crystal silicon brittle material, and is generally of a cylindrical structure, and in practical application, the silicon rod 10 to be cut of a cylindrical structure is vertically placed on the silicon rod bearing table 21 in a manner of circular section contact. Further, the contact surface of the silicon rod carrying table 21 for contacting with the silicon rod has damping to provide a certain friction force capable of driving the silicon rod.

The silicon rod carrying device may provide at least one direction of movement for the silicon rod carrying table 21. For example, the silicon rod carrying table 21 may travel in the Y direction (Y axis direction as shown in fig. 1) by a Y-direction movement mechanism. In one implementation, the silicon rod bearing table 21 is a mesa structure with a cross section of approximately ︻ (similar to a common gantry structure), and two legs of the ︻ type structure are moved on the table 11 by a Y-direction movement mechanism. The Y-direction motion mechanism may include: two parallel sliding rails are laid on two sides of the workbench 11 (see the X-axis trend in fig. 1) which are contacted with two support legs of the silicon rod bearing table 21 in a manner of approaching to or separating from the silicon rod bearing device; the two sliding seats or sliding blocks are respectively arranged at the bottoms of the two supporting legs of the silicon rod bearing table 21 and are matched with the corresponding two parallel sliding rails; and the driving device is used for driving the silicon rod bearing table 21. In practice, the silicon rod carrying table 21 is driven by a driving device (such as a common servo motor) to advance (move from the waiting area to the cutting area) or retract (move from the cutting area to the waiting area) along the laid slide rail in the Y direction.

In order to maintain the stability of the vertical silicon rod to be cut 10 on the silicon rod carrying table 21 in the Y direction (Y axis direction as shown in fig. 1) and the subsequent square cutting operation, in some embodiments, the silicon rod carrying table is further provided with a positioning mechanism, and the positioning mechanism includes a bottom positioning member for positioning the bottom of the vertical silicon rod to be cut 10, preferably, in a practical application, the bottom positioning member may be a silicon rod fixture fixed on the silicon rod carrying table 21, and the silicon rod fixture includes a collet and a clamping jaw (not shown in the figure) disposed on the periphery of the collet, where the collet is adapted to the silicon rod to be cut 10 to be limited, and the clamping jaw is plural (in this embodiment, since the silicon rod needs to be cut into a rectangular-like section from an initial circular section, so that four parallel cutting planes are cut along the length direction of the silicon rod, and the number of each clamping jaw is preferably four, and extends upwards from the bottom of the collet respectively). In one case, for the arrangement of the clamping jaw, the clamping jaw can be designed to be an elastic clamping jaw with elasticity, and the clamping jaw is connected to the bottom of the collet in a meshed manner (a fluted disc is arranged at the connecting end of the clamping jaw, a fluted disc adjusting column meshed with the fluted disc is arranged at the bottom of the collet, and a plurality of sections of adjusting teeth are designed on the fluted disc adjusting column, so that the opening and closing of the clamping jaw can be controlled through the up-and-down movement of the fluted disc adjusting column). Thus, when the silicon rod 10 to be cut is placed on the bottom support, the silicon rod 10 to be cut abuts against the bottom support and ensures that the silicon rod 10 to be cut is concentric with the bottom support, and at the moment, the clamping jaw can clamp the bottom of the silicon rod 10 to be cut well. In order to prevent the clamping jaw from scratching the silicon rod 10 to be cut, the contact part of the clamping jaw and the silicon rod 10 to be cut is designed smoothly or a buffer pad is additionally arranged on the inner surface of the clamping jaw, which is to be contacted with the silicon rod. Of course, the silicon rod fixture is only a preferred embodiment, but the bottom positioning member is not limited thereto, and in other embodiments, the bottom positioning member may be an air chuck or an adhesive bonding surface coated with an adhesive, which has the effect of fixing the silicon rod 10 to be cut on the silicon rod carrying table 21.

In addition, the silicon rod carrying apparatus may further include a silicon rod pressing mechanism 22, and the silicon rod pressing mechanism 22 may correspond to the silicon rod carrying table 21 for pressing against the top of the silicon rod 10 to be cut. In the present embodiment, the silicon rod pressing mechanism 22 is movable in at least one direction. As shown in fig. 1, the silicon rod pressing mechanism 22 can move in the X-direction by a first X-direction movement mechanism. The first X-direction movement mechanism is disposed in the X-direction (X-axis direction as shown in fig. 1) of the frame 1, and is used for moving the device for processing the silicon rod in the X-direction. The silicon rod pressing mechanism 22 may further include a pressing support 221 slidably disposed on the first X-direction movement mechanism, and a pressing member movably disposed on the pressing support 221. The pressing support 221 is movably disposed on the base 1 along the Y direction by a first X-direction movement mechanism.

The first X-direction movement mechanism may include: the first X-direction sliding rail, the first X-direction sliding block and the first X-direction driving source. As shown in fig. 1, the first X-direction slider may be disposed on the pressing support 221 through a guide plate and adapted to the corresponding first X-direction guide rail 200, and the first X-direction driving source may be, for example, an X-direction motor or an X-direction cylinder. In practical applications, to enable the pressing support 221 to stably move along the X direction, a dual-rail design may be adopted, that is, two first X-direction rails 200 are adopted, and the two first X-direction rails 200 are disposed in parallel along the X direction. In this way, the pressing support 221 can move along the X direction by the first X direction movement mechanism, and the movement stability of the pressing support 221 during the X direction movement can be ensured.

The pressing member may include: the lifting driving structure 223 is arranged on the pressing support 221, and the pressing block 224 is arranged at the bottom of the lifting driving structure 223. The pressing block 224 is driven by the elevation driving structure 223 to move up and down. The lifting driving structure 223 may be, for example, a lifting cylinder with a lifting rod, where the lifting rod of the lifting cylinder is connected to the pressing block 224, so that the lifting rod can be controlled to stretch and retract by using the lifting cylinder to drive the pressing block 224 to perform lifting motion. The pressing block 224 is adapted to the silicon rod 10 to be cut, for example, the pressing block 224 may be a cake-shaped pressing block adapted to the cross-sectional size of the silicon rod 10 to be cut.

The silicon rod squaring device can further comprise a silicon rod transferring device used for transferring the silicon rods to be cut to the silicon rod bearing device and transferring the cut silicon rods out of the silicon rod bearing device. Referring to fig. 2, fig. 2 corresponds to fig. 1, and shows a schematic structural diagram of a silicon rod opening apparatus equipped with a silicon rod transferring device according to the present application in one embodiment.

Referring to fig. 3, a schematic structure of the silicon rod transferring apparatus 4 in fig. 2 is shown. Referring to fig. 2 and 3, a silicon rod transfer device 4 in the silicon rod squaring apparatus of the present application is adjacently disposed to a silicon rod carrying device, and includes: the reversing carrier 41, a silicon rod clamp 43 arranged on the reversing carrier 41 and a reversing driving mechanism for driving the reversing carrier to do reversing movement.

The reversing carrier 41 is a main body device for setting other various components in the silicon rod transferring device, and the other various components mainly include, but are not limited to, a silicon rod clamp 43, and other components can also be, for example, a mechanical structure, an electrical control system, a numerical control device, and the like. In the present embodiment, the reversing carrier 41 may include a base, a top frame opposite to the base, and a supporting frame disposed between the base and the top frame. In addition, another important function of the reversing carrier 41 is to support reversing conversion of the silicon rod clamp 43 by reversing movement. The reversing carrier 41 can be moved in reversing direction, for example by means of a reversing drive. With the reversing driving mechanism, the reversing carrier 41 can be driven to perform reversing motion so that the silicon rod clamps 43 on the reversing carrier 41 clamp the silicon rods 10 to be cut and transfer the silicon rods 10 to be cut from the loading and unloading zone to the silicon rod bearing tables 21 corresponding to the waiting zone, or clamp the cut silicon rods 12 on the silicon rod bearing tables 21 corresponding to the waiting zone and transfer the cut silicon rods 12 from the waiting zone to the loading and unloading zone.

In a specific implementation manner, the reversing driving mechanism for realizing the reversing motion of the reversing carrier 41 may include a rotating shaft and a rotating motor, the reversing carrier 41 is connected to an installation foundation (the installation foundation may be, for example, a base of a silicon rod squaring device or a working platform of the silicon rod squaring device) below the rotating shaft through the rotating shaft, an outer expanding installation edge may be arranged at a connection end used for being connected with the reversing carrier 41 in the rotating shaft, installation holes are uniformly distributed on the installation edge, correspondingly, an installation hole is also formed in a central position of a base in the reversing carrier 41, the base in the reversing carrier 41 is in butt joint with the rotating shaft during installation, the installation hole on the base is aligned with the installation hole on the rotating shaft, and then the installation hole is penetrated and attached by a locking element such as a bolt, so as to complete the assembly of the reversing carrier 41. When steering movement is implemented, the rotating motor is started to drive the rotating shaft to rotate so as to drive the reversing carrier 41 to rotate to realize reversing movement. The rotation of the drive rotation shaft may be designed as a unidirectional rotation, which may be, for example, a unidirectional clockwise rotation or a unidirectional counterclockwise rotation, or as a bidirectional rotation, which may be, for example, a simultaneous clockwise rotation and counterclockwise rotation. In addition, the angle at which the rotation shaft is driven to rotate may be set according to the actual construction of the silicon rod transfer device. Furthermore, the base in the reversing carrier 41 may be a disc structure, a rectangular disc, or an oval disc, and the central position thereof is connected to the rotating shaft, but the shape of the base is not limited thereto, and in other embodiments, the base may also be other shapes.

At least one silicon rod clamp 43 is provided on the reversing carrier 41 for clamping a respective silicon rod. In the silicon rod squaring apparatus shown in fig. 2 and 3, one silicon rod holder 43 is provided on a certain mounting surface of the reversing carrier 41, and the silicon rod holder 43 can be used to hold a round silicon rod (i.e., a silicon rod to be cut) and a silicon square (i.e., a cut silicon rod). In this way, by driving the reversing carrier 41 in a reversing motion, the silicon rod clamps 43 on the reversing carrier 41 are switched between the loading and unloading zone and the waiting zone for transferring the silicon rods to be cut and between the waiting zone and the loading and unloading zone for transferring the cut silicon rods. In practical applications, the rotation angle of the reversing motion of the reversing carrier 41 is determined according to the positional relationship between the loading and unloading area and the waiting area, and in one embodiment, the loading and unloading area and the waiting area are disposed opposite to each other, and the silicon rod transferring device 4 is disposed between the loading and unloading area and the waiting area, so that the reversing carrier 41 is driven by the reversing driving mechanism to rotate by 180 °. However, in other embodiments, if the loading/unloading area and the waiting area are disposed at an angle of 90 °, the reversing carrier 41 is driven by the reversing driving mechanism to rotate at an angle of 90 °. However, no particular limitation is imposed on the positional relationship between the loading and unloading areas and the waiting areas, and the arrangement order and the arrangement angles therebetween may be changed, so long as unnecessary interference is not caused between the stations, and the rotation direction and the rotation angle of the reversing carrier 41 are adaptively adjusted.

As described above, the silicon rod squaring device of the application can perform squaring and cutting operations on silicon rods, and round silicon rods in a cylindrical shape can be formed into silicon cubes with rectangular cross sections after squaring and cutting operations. Therefore, the silicon rod holder 43 according to the present application can hold both a single-wafer silicon rod and a silicon square.

The silicon rod jigs 43 and the following are described in detail.

The silicon rod clamp 43 further comprises at least two silicon rod clamps 431, wherein the at least two silicon rod clamps are arranged at intervals. In one embodiment, both the silicon rod to be cut and the cut silicon rod are placed vertically, and therefore, at least two silicon rod clamps 431 are disposed up and down.

In a specific implementation, any one of the silicon rod clamps 431 may further comprise: the clamping arm installation seat 433 and at least two clamping arms 435, wherein the clamping arm installation seat 433 is arranged on the reversing carrier 41, and the at least two clamping arms 435 are movably arranged on the clamping arm installation seat 433. In an alternative embodiment, two clamping arms 435 are arranged symmetrically, and a single clamping arm 435 is provided with two clamping teeth 437 arranged front and back, so that the clamping teeth 437 (four in total) on the two clamping arms 435 can form a clamping space for clamping a single-wafer silicon rod or silicon square body. Additionally, the silicon rod clamp 431 may be utilized to provide centering adjustment. In general, the center of the clamping space formed by the two clamping arms 435 coincides with the center of the silicon rod to be cut and the center of the cut silicon rod in the clamped state of the clamping arms 435 in the silicon rod clamping member 431. Therefore, when the silicon rod to be cut or the cut silicon rod placed upright is clamped by the silicon rod clamp 431, the two clamp arms 435 in the silicon rod clamp 431 are contracted, and the clamp teeth 437 in the clamp arms 435 are abutted against the silicon rod to be cut or the cut silicon rod. In the process that the clamping arms 435 contract and clamp the silicon rod to be cut or the cut silicon rod, the silicon rod to be cut or the cut silicon rod is pushed by the two clamping arms 435 at both sides and moves toward the central area of the clamping space until the silicon rod to be cut or the cut silicon rod is clamped by the two clamping arms 435 in the silicon rod clamping member 431, at which time the center of the silicon rod to be cut or the cut silicon rod can be located at the center of the clamping space of the silicon rod clamping member 431. Of course, a buffer component can be additionally arranged on the clamping teeth 437 in the clamping arm 435, so as to avoid damage to the surface of the silicon rod to be cut or the silicon rod already cut in the process of clamping the silicon rod to be cut, and achieve a good effect of protecting the silicon rod to be cut or the silicon rod already cut.

In order to enable the two clamping arms 435 in the silicon rod clamping member 431 to smoothly and firmly clamp silicon rods to be cut or cut with different sizes, the silicon rod clamping member 431 further comprises a clamping arm driving mechanism for driving the two clamping arms 435 to open and close. In one embodiment, the clamp arm driving mechanism may be, for example, a cylinder with a telescopic shaft. For example, two clamping arms 435 belonging to the silicon rod clamping member 431 share a cylinder 432, the cylinder is provided with two (sleeve) telescopic shafts, each (sleeve) telescopic shaft is connected with one clamping arm 435, and the clamping arms 435 can be slidably arranged on the reversing carrier 41 through a sliding rail, so that the telescopic shafts can be controlled by the cylinder to stretch and retract so as to drive the clamping arms 435 to slide on the sliding rail to realize the clamping action. For example, a cylinder may be configured for each clamping arm 435, a telescopic shaft of the cylinder is connected to the clamping arm 435, and the clamping arm 435 may be slidably disposed on the reversing carrier 41 through a sliding rail, so that the telescopic shaft may be controlled by the cylinder to stretch and retract to drive the clamping arm 435 to slide on the sliding rail to implement a clamping action. Of course, in other embodiments, the clamp arm driving mechanism may take other forms.

As known to those skilled in the art, regarding silicon rods, which are formed by cutting off an original long silicon rod, there is a tendency to make the difference in size between silicon rods different, and since the silicon rod holder 43 is used for holding a silicon rod (a silicon rod to be cut or a cut silicon rod) in an upright state, the influence of the aforementioned difference in size is mainly expressed in a concern as to whether the difference in length of the silicon rod corresponds to the holding of the silicon rod by the silicon rod holder 431 in the silicon rod holder 43.

To reduce or even eliminate the risk that the rod holder 431 may not be able to hold the rod, the rod holder 43 may be of different design.

In one implementation, the silicon rod clamps 43 are fixed clamps, that is, as many silicon rod clamps as possible are fixedly arranged on the reversing carrier 41 in a vertical manner, and the interval between two adjacent silicon rod clamps 431 in the silicon rod clamps 431 can be set smaller, so that silicon rods with various specifications and lengths can be covered by the silicon rod clamps 431. For example, if the length of the silicon rod is longer, more silicon rod clamping members 431 on the reversing carrier 41 are used to participate in clamping; if the length of the silicon rod is short, fewer silicon rod clamps 431 on the reversing carrier 41 are used to engage in the clamping, for example, several silicon rod clamps 431 located below engage in the clamping, while those silicon rod clamps 431 located above and above the silicon rod do not engage.

In other implementations, the silicon rod clamp 43 is a movable clamp, that is, the silicon rod clamp 431 is movably disposed on the reversing carrier 41 in a vertical manner, and since the silicon rod clamp 431 is movably designed, the number of the silicon rod clamps 431 can be greatly reduced, and generally two or three silicon rod clamps can be satisfied. Therefore, the movable clamping piece can cover silicon rods with various specifications and lengths. For example, if the length of the silicon rod is long, the movably provided silicon rod holders 431 are moved, and the holding distance between the two silicon rod holders 431 is extended; if the length of the silicon rod is short, the movably arranged silicon rod clamps 431 are moved, so that the clamping distance between the two silicon rod clamps 431 is shortened.

There are also different variations of the silicon rod clamp 43 for the movable silicon rod clamp. Taking two silicon rod clamps 431 as an example, in an alternative embodiment, one of the two silicon rod clamps 431 is a movable design and the other silicon rod clamp 431 is a fixed design, so that in practical application, the clamping distance between the two silicon rod clamps 431 is adjusted by moving the one silicon rod clamp 431 with the movable design. From the above, it is known that the silicon rod (which may be either the silicon rod to be cut or the cut silicon rod) is placed vertically, and therefore, the bottom of the silicon rod can be always relatively easily determined regardless of the specification length of the silicon rod, and therefore, it is preferable that the upper one 431 of the two silicon rod clamps 431 is designed to be movable, so that only the position of the upper silicon rod clamp 431 needs to be adjusted.

To achieve the displacement of the silicon rod holder 431, the silicon rod holder 431 of the movable design may be provided with a guiding drive. The guide driving mechanism can be used for driving the movably designed silicon rod clamping member 431 to move up and down along the silicon rod clamping member mounting member. In one implementation, the guiding drive mechanism may, for example, comprise: the guide rail and the guide motor are vertically arranged, the base of the silicon rod clamping piece 431 can be rested on the guide rail through the sliding block, and therefore, when the position of the silicon rod clamping piece 431 above the guide rail needs to be adjusted, the guide motor drives the silicon rod clamping piece 431 to move up and down along the guide rail. By controlling the silicon rod clamping pieces 431 with movable designs, the clamping distance between the two silicon rod clamping pieces 431 can be adjusted, so that silicon rods with different specification lengths can be effectively clamped.

In another alternative embodiment, both the two silicon rod clamps 431 are of a movable design, so that in practical applications, the clamping distance between the two silicon rod clamps 431 can be adjusted by moving them. Since the silicon rod clamps 431 are of a movable design, at least one of the two silicon rod clamps 431 needs to be provided with a guide driving mechanism for driving the two silicon rod clamps 431 to move up and down.

In fact, under the condition that the two silicon rod clamping members 431 are both of a movable design, the guiding driving mechanism can not only adjust the clamping distance between the two silicon rod clamping members 431 to effectively clamp silicon rods with different specification lengths, but also achieve the purpose of lifting the clamped silicon rods, and after the two silicon rod clamping members 431 effectively clamp the silicon rods, the silicon rods can be lifted by driving the silicon rod clamping members 431 to move up and down. Specifically, taking the example in which the upper silicon rod holder 431 is provided with a guide driving mechanism, first, the upper silicon rod holder 431 is moved up and down by the guide driving mechanism to adjust the holding distance with the lower silicon rod holder 431; then, the clamping arms 435 are driven by the clamping arm driving mechanism in each silicon rod clamping piece 431 to perform clamping action so as to smoothly and firmly clamp the silicon rod; then, the upper silicon rod clamping member 431 is driven to move upwards by the guide driving mechanism, and at the moment, the clamped silicon rod and the lower silicon rod clamping member 431 move upwards together due to the friction force, wherein the clamped silicon rod moves upwards by using the friction force between the upper silicon rod clamping member 431 and the silicon rod, and the silicon rod clamping member 431 moves upwards by using the friction force between the silicon rod and the lower silicon rod clamping member 431, so that the effect of lifting the silicon rod is achieved. The upper silicon rod clamping member 431 drives the silicon rod and the lower silicon rod clamping member 431 to move downwards under the drive of the guide driving mechanism, so that the effect of dropping the silicon rod is achieved, and the description is omitted.

In other variations, for example, a guide driving mechanism is provided on the lower silicon rod holder 431 of the two silicon rod holders 431, and the structure, arrangement and driving operation of the guide driving mechanism are similar to those of the guide driving mechanism of the upper silicon rod holder 431, for example, the lower silicon rod holder 431 is driven by the guide driving mechanism to move up and down to adjust the holding distance between the lower silicon rod holder 431 and the upper silicon rod holder 431, and the lower silicon rod holder 431 is driven by the guide driving mechanism to move up and down together with the upper silicon rod holder 431. For example, if the two silicon rod holders 431 are both provided with a guiding driving mechanism, the manner of setting and driving operation of the guiding driving mechanism and the manner of movement of the two silicon rod holders 431 are not described in detail herein.

In the case that the silicon rod clamping member 431 provided for the movable type moves up and down to be adapted to the silicon rods of different specification lengths for clamping, it is necessary to know the specification length of the silicon rod currently required to be clamped in addition to the silicon rod clamping member 431 adopting the movable type structural design, the silicon rod clamping member 431 being required to be provided with a guide driving mechanism, and the like. In view of this, the silicon rod squaring apparatus of the present application may further include a height detector 430 for detecting the height of the vertically placed silicon rod as a basis for the subsequent upward or downward movement and the moving distance of the movably disposed silicon rod holder 431.

Accordingly, in the present embodiment, the silicon rod to be cut is formed into a silicon square body (i.e. a cut silicon rod) after the squaring cutting operation and other related operations, and the length is generally unchanged during the process of forming the silicon square body from the silicon rod to be cut, so that the silicon rod clamping member 431 movably disposed on the silicon rod clamping member 43 does not need to be adjusted again when the silicon rod clamping member 43 is used to clamp the silicon square body located at the squaring cutting operation station.

In addition, the silicon rod clamp in the silicon rod transferring device can be changed in other ways. For example, the silicon rod handling device may be configured with two silicon rod clamps that may be respectively disposed on opposite mounting surfaces in the reversing carrier 41. And, the two silicon rod clamps may be the same or different. In the same case, the two silicon rod clamps are used for clamping round silicon rods and silicon cubes. In a different case, as shown in fig. 4, a schematic structural diagram of a silicon rod transferring device in an embodiment is shown, where one of the two silicon rod clamps 43, 44 on the reversing carrier 41 is used for clamping a round silicon rod, and the other silicon rod clamp 44 is used for clamping a silicon square body.

Further, the silicon rod handling device 4 of the present application is further capable of providing at least one direction of movement. For example, the silicon rod handling apparatus may further include an advancing and retreating mechanism provided along the Y axis, and the advancing and retreating mechanism may include: a forward and backward guide rail and a forward and backward motor, wherein the forward and backward guide rail is arranged along the Y axis, the base of the reversing carrier 41 can be rested on the forward and backward guide rail through a sliding block, so that when the position of the reversing carrier 41 needs to be adjusted, the reversing carrier 41 is driven by the forward and backward motor to advance and retreat along the forward and backward guide rail. By controlling the advance and retreat of the reversing carrier 41 along the advance and retreat guide rail, the position of the reversing carrier 41 in the Y axis can be adjusted, so that the silicon rod clamp 43 on the reversing carrier 41 can correspond to the silicon rod carrying table 21 in the loading and unloading area or the silicon rod carrying table 21 in the waiting area.

With the silicon rod transferring device 4, handling of the silicon rods can be achieved, i.e. the silicon rods to be cut can be transferred from the handling zone to the silicon rod carriers corresponding to the waiting zone or the cut silicon rods can be transferred from the silicon rod carriers corresponding to the waiting zone to the handling zone.

In practical applications, the silicon rod squaring device of the present application may further include a silicon rod measuring device disposed in the waiting area, for measuring the dimensions of the silicon rod 10 to be cut or the cut silicon rod 12 after squaring and cutting, so as to determine whether the silicon rod meets the product requirements. On the one hand, after the silicon rod 10 to be cut is transferred from the loading and unloading area to the silicon rod bearing table 21 corresponding to the waiting area by the silicon rod transferring device 3 and before the squaring and cutting operation is performed, the dimension measurement and the position measurement of the silicon rod 10 to be cut need to be performed, and if necessary, the position of the silicon rod 10 to be cut can still be adjusted by the silicon rod transferring device 3. On the other hand, after the squaring cutting operation, it is also necessary to perform dimensional measurement on the cut silicon rod 12. By using the silicon rod measuring device, whether the silicon rod meets the product requirement after the cutting operation is performed by measuring the sizes of the silicon rod 10 to be cut and the cut silicon rod 12 can be checked, and the abrasion condition of the wire cutting device can be indirectly obtained by measuring the sizes of the silicon rod 10 to be cut and the cut silicon rod 12, so that the wire cutting device is favorable for real-time calibration or correction, even maintenance or replacement.

The wire cutting device 3 is arranged on the machine base 1 and is used for squaring and cutting the silicon rod 10 to be cut carried on the silicon rod carrying table 21 in the silicon rod conversion device 2. In practical application, the wire cutting device comprises at least one wire cutting unit corresponding to the cutting area.

In the silicon rod squaring device shown in fig. 1 and 2, the wire cutting apparatus 3 includes: the wire cutting support 31 is arranged on the machine base 1 in a lifting manner, and the at least one wire cutting unit 33 is arranged on the wire cutting support 31, wherein the wire cutting support 31 can move up and down relative to the machine base 1 through a lifting mechanism, the at least one wire cutting unit 33 corresponds to a cutting area and is provided with a cutting line 331 forming a cutting line net, and the at least one wire cutting unit 33 can be used for squaring and cutting the silicon rod 10 to be cut, which is carried by the silicon rod carrying table 21 corresponding to the cutting area in the silicon rod conversion device 2.

The wire cutting support 31 is arranged on the mounting structure of the stand 1 in a liftable manner through a lifting mechanism. In an embodiment, the lifting mechanism may include a mechanism that can implement vertical displacement of the wire-electrode cutting support 31 by using a lifting motor, a lifting guide rail, and a lifting slider, where the lifting guide rail is vertically disposed on the mounting structure of the machine base 1 along the Z axis, and the lifting slider is disposed on the back of the wire-electrode cutting support 31 and is matched with the lifting guide rail, so that the wire-electrode cutting support 31 can implement a mounting structure that stably lifts on the machine base 1, and a double-guide-rail design may be adopted, that is, two lifting guide rails are adopted, and the two lifting guide rails are disposed in parallel. The wire-cutting support 31 can be moved up and down relative to the machine base 1 by means of an up-down guide and the up-down slide, driven by the up-down motor, which can be, for example, a servomotor.

The wire cutting unit 33 includes at least: a wire holder 333 provided on the wire cutting support 31, a plurality of cutting wheels 335 provided on the wire holder 333, and cutting wires 331 sequentially wound around the respective cutting wheels 335.

In practical applications, the wire cutting unit 33 comprises at least eight cutting wheels 335, and the at least eight cutting wheels 335 can be combined into two pairs of cutting wheel sets, i.e. one cutting wheel set is formed by two cutting wheels, and a pair of cutting wheel sets is formed by two cutting wheel sets. In practical applications, the wire cutting unit 33 comprises two pairs of cutting wheel sets, namely a first pair of cutting wheel sets and a second pair of cutting wheel sets. The first cutting wheel set comprises a first cutting wheel set and a second cutting wheel set, which are respectively arranged at the left side and the right side of the wire frame 333, wherein the first cutting wheel set is positioned at the left side of the wire frame 333 and comprises two cutting wheels 335 arranged front and back, and the second cutting wheel set is positioned at the right side of the wire frame 333 and comprises two cutting wheels 335 arranged front and back; the second pair of cutting wheel sets comprises a third cutting wheel set and a fourth cutting wheel set, which are respectively arranged on the front side and the rear side of the wire frame 333, wherein the third cutting wheel set is positioned on the front side of the wire frame 333 and comprises two cutting wheels 335 arranged left and right, and the fourth cutting wheel set is positioned on the rear side of the wire frame 333 and comprises two cutting wheels 335 arranged left and right.

The cutting lines 331 are sequentially wound around the cutting wheels 335 in the wire cutting unit 33 to form a cutting wire net. In practical applications, the cutting line 331 is sequentially wound around eight cutting wheels in the wire cutting unit 33 to form four cutting line segments, and the four cutting line segments form a cutting line net. In practical applications, the cutting line 331 forms a first cutting line segment after winding around two cutting wheels 335 disposed in the first cutting wheel set, the cutting line 331 forms a second cutting line segment after winding around two cutting wheels 335 disposed in the second cutting wheel set, the cutting line 331 forms a third cutting line segment after winding around two cutting wheels 335 disposed in the third cutting wheel set, and the cutting line 331 forms a fourth cutting line segment after winding around two cutting wheels 335 disposed in the fourth cutting wheel set. Thus, the first cutting line segment, the second cutting line segment, the third cutting line segment and the fourth cutting line segment are matched to form a cutting line net in a 'well' -shaped. In some embodiments, two adjacent cutting line segments are perpendicular to each other and two opposing cutting line segments are parallel to each other. Specifically, a first cutting line segment and a second cutting line segment in the first cutting wheel set are parallel to each other, a third cutting line segment and a fourth cutting line segment in the second cutting wheel set are parallel to each other, and the first cutting line segment and the second cutting line segment in the first cutting wheel set are perpendicular to the third cutting line segment and the fourth cutting line segment in the second cutting wheel set.

In this way, in practical application, when the wire frame 333 of the wire cutting unit 33 descends relative to the machine base 1 along with the wire cutting support 31, the wire cutting net formed by the cutting wire segments on the wire frame 333 square-cuts the silicon rod 10 to be cut carried by the silicon rod carrying table 21 located in the cutting area along the length direction of the silicon rod.

In fact, the wire-cutting unit 33 may be modified in other ways, for example, in one embodiment, the wire-cutting unit may include four cutting wheels, which may be combined into a pair of cutting wheel sets, i.e., two cutting wheels forming one cutting wheel set and two cutting wheel sets forming a pair of cutting wheel sets. Each cutting wheel group comprises two cutting wheels which are oppositely arranged and cutting line segments which are wound on the two cutting wheels, and the two cutting line segments in the two cutting wheel groups which are different are mutually parallel. The spacing between the two cutting wheels in each cutting wheel set corresponds to the cross-sectional dimension of the silicon rod to be cut. For example, the two cutting wheel groups included in the pair of cutting wheel groups are respectively arranged at the left side and the right side of the wire frame, wherein one cutting wheel group comprises two cutting wheels arranged front and back, a cutting line segment is wound between the two cutting wheels, the other cutting wheel group also comprises two cutting wheels arranged front and back, a cutting line segment is wound between the two cutting wheels, and the two cutting line segments are parallel to each other.

In practical applications, two squaring and cutting steps are required for squaring and cutting the silicon rod to be cut for a pair of cutting wheel sets, and after the first squaring and cutting, the cutting position of the silicon rod to be cut is adjusted again. Thus, in one implementation, the silicon rod bearing table may be configured in a rotating structure, such as: the silicon rod bearing table can rotate through a rotating mechanism, so that the silicon rod bearing table is driven to rotate through the rotating mechanism, the silicon rod to be cut can be smoothly rotated (for example, rotated by 90 degrees), and therefore the two cutting line segments in the pair of cutting wheel sets can carry out secondary squaring cutting on the rotated silicon rod to be cut, and squaring cutting of the silicon rod to be cut is completed. In addition, the compaction block in the silicon rod jacking mechanism can also perform rotary motion.

Therefore, the silicon rod bearing table and the silicon rod pressing mechanism are arranged to be of a rotary structure, so that the silicon rod to be cut can be smoothly rotated (for example, rotated by 90 degrees), and the two cutting lines in the pair of cutting wheel sets can cut the rotated silicon rod to be cut for the second time, so that the square of the silicon rod to be cut is completed.

In the implementation mode that the silicon rod bearing table and the silicon rod jacking mechanism are arranged into a rotary structure, the silicon rod bearing table can be designed to be capable of rotating and moving, and a compressing block in the silicon rod jacking mechanism is connected to the support in a shaft rotating manner, so that the silicon rod bearing table or the compressing block can be linked with a rotary driving device. In some embodiments, when the silicon rod bearing table is linked with a rotary driving device, the silicon rod bearing table is used as a driving rotary part and the compaction block is used as a driven rotary part; in some embodiments, the hold-down block is used as the driving rotating member and the silicon rod bearing table is used as the driven rotating member when the hold-down block is coupled to a rotary driving device. Taking a rotary driving device as an example, the silicon rod bearing table is linked with a rotary driving device, and the silicon rod jacking mechanism can be matched with the silicon rod bearing table below the silicon rod jacking mechanism, specifically, after the silicon rod to be cut is vertically placed on the rotary silicon rod bearing table, the lifting driving structure drives the compressing block to move downwards along the bearing until the compressing block is propped against the top of the silicon rod to be cut. Subsequently, when the silicon rod to be cut needs to be rotated, the rotary driving device drives the linked silicon rod bearing table or the compression block to rotate, and the silicon rod to be cut is driven to rotate along with the rotation by utilizing the friction force among the silicon rod bearing table, the silicon rod to be cut and the compression block, so that the adjustment of the working face or the working area in the silicon rod to be cut is realized, and the adjusted working face or the working area in the silicon rod to be cut is processed. The rotational speed and the rotational angle of the silicon to be cut can be controlled by a rotary drive. In a specific embodiment, the rotary drive device may then be a rotary electric machine, for example.

In addition, in certain embodiments, the wire cutting unit 33 may further include at least one of the following: wire guide wheels arranged on the wire frame 333 and/or the wire cutting support 31 for guiding the cutting wire 331; tension wheels arranged on the wire frame 333 and/or the wire cutting support 31 for adjusting the tension of the cutting wire 331; and a wire storage barrel (the wire storage barrel can further comprise a paying-off barrel and a wire collecting barrel) arranged on the machine base 1 and used for collecting and releasing the cutting wire 331.

It should be noted that, in consideration of the situations of achieving complete cutting of the silicon rod 10 to be cut and avoiding damage to the cutting line due to blocking, the technical solution provided by the present application performs a certain structural design on the silicon rod bearing table 21 for bearing the silicon rod 10 to be cut. For example, the silicon rod bearing table 21 is a table structure with a rectangular section, the size of a bearing surface in contact with the silicon rod in the table structure is slightly smaller than the section of a cut silicon rod formed by cutting the silicon rod to be cut, in this way, the wire frame 333 in the wire cutting device 3 descends relative to the machine base 1 along with the wire cutting support 31, the cutting wire net formed by each cutting wire segment on the wire frame 333 cuts the silicon rod to be cut 10 borne by the silicon rod bearing table 21 in the cutting area, and when the cutting wire net reaches the bottom of the silicon rod to be cut 10, the cutting wire net can continue to descend without obstruction until penetrating the silicon rod to be cut 10, so that the silicon rod to be cut 10 is completely cut. Of course, the structure of the silicon rod carrying table 21 is not limited to this, in some embodiments, the silicon rod carrying table 21 is a table structure with a circular section or a rectangular section, and the size of the carrying surface, which contacts the silicon rod, of the table structure is larger than the section of the cut silicon rod formed by cutting the silicon rod to be cut, so that the table structure is provided with cutting grooves matched with each cutting line segment in the cutting line net, and in particular, the table structure may be provided with four cutting grooves corresponding to the first cutting line segment, the second cutting line segment, the third cutting line segment, and the fourth cutting line segment. In this way, the wire frame 333 in the wire cutting device 3 descends relative to the machine base 1 along with the wire cutting support 31, the wire cutting net formed by each cutting wire segment on the wire frame 333 square-cuts the silicon rod 10 to be cut carried by the silicon rod carrying table 21 in the cutting area, the wire cutting net reaches the bottom of the silicon rod 10 to be cut and continues to descend until penetrating the silicon rod 10 to be cut, and each cutting wire segment just can be immersed into the corresponding cutting groove, so that the silicon rod to be cut is completely cut.

The silicon rod cutting apparatus shown in fig. 2 will be described below as an example. When the silicon rod squaring device shown in fig. 2 is applied to perform squaring and cutting operations on a silicon rod, the operation process may generally include: the silicon rod 10 to be cut is placed on the silicon rod carrying table 21 located in the waiting area by the silicon rod transferring device 4. Then, the silicon rod carrying table 21 is advanced in the Y direction by the Y-direction moving mechanism, and moved from the waiting area to the cutting area, at which time the wire cutting unit 33 in the wire cutting apparatus 3 is opposed to the silicon rod to be cut on the silicon rod carrying table 21 located in the cutting area. Then, the wire cutting support 31 in the wire cutting device 3 is driven to descend relative to the machine base 1, the wire cutting net formed by the cutting wire segments on the wire cutting unit 33 in the wire cutting device 3 performs squaring cutting on the silicon rod 10 to be cut carried by the silicon rod carrying table 21 in the cutting area until the wire cutting net penetrates through the silicon rod 10 to be cut, complete cutting of the silicon rod 10 to be cut is completed (see fig. 5), and the silicon rod 12 and the edge skin 13 are formed after squaring cutting.

In the related art, the silicon rod 10 to be cut is cut to form a side skin, and the side skin is usually detached from the cut silicon rod and removed from the silicon rod cutting device by manual operation of an operator for unloading the side skin, which is not only inefficient, but also causes the side skin to collide with the cut silicon rod during the handling process, thereby increasing the risk of damaging the cut silicon rod. In view of this, the silicon rod squaring device of the present application further comprises a side skin unloading means for unloading the side skin formed after the wire cutting means 3 squaring and cutting the silicon rod 10 to be cut.

In practical application, the edge skin unloading device comprises a staggering mechanism, wherein the staggering mechanism is used for driving the edge skin and the cut silicon rod to generate relative lifting displacement, so that the top end of the edge skin protrudes out of the cut silicon rod, and therefore the edge skin and the cut silicon rod can be staggered mutually, the edge skin is easier to grasp, and the edge skin can be unloaded after being grasped later.

In one implementation, the staggering mechanism may be, for example, a side skin lifting mechanism for lifting the side skin to be in ascending displacement relative to the cut silicon rod such that the top end of the side skin protrudes from the cut silicon rod. Referring to fig. 6 and 7, fig. 6 is a schematic structural view of the silicon rod squaring device according to the present application under a certain view angle in the state of fig. 5, and fig. 7 is a schematic structural view of a part of the edge skin lifting mechanism. Referring to fig. 5 to 7, the side skin unloading device includes: the edge skin lifting mechanism 5 is used for driving the edge skin 13 and the cut silicon rod 12 to perform relative lifting displacement, so that the top end of the edge skin 13 protrudes out of the cut silicon rod 12. In the present embodiment, the edge skin lifting mechanism 5 for driving the edge skin 13 and the cut silicon rod 12 to relatively lift and displace is arranged on the wire cutting device 3, and can lift and displace along with the wire cutting device 3.

In practical applications, since the silicon rod is required to be cut into a rectangular-like section from an initial circular section, four parallel cutting planes are cut along the length direction of the silicon rod to be cut, and four arc side skins are formed, the number of the side skin lifting mechanisms 5 is preferably four, and the side skin lifting mechanisms are arranged on two opposite sides of the wire frame 333 in the wire cutting unit 33.

In particular, the lift mechanism 5 may comprise a lifting member 51 that is telescopically movable, in particular, the lifting member 51 may be telescopically movable by a telescopic member 53, such that the lifting member 51 abuts against the edge skin 13 and holds the bottom end of the edge skin 13 by telescopic movement.

The jacking members 51 may further include abutment plates and bearing plates. The supporting plate extends upwards from the bottom of the supporting plate, further, the supporting plate can be an arc plate matched with the arc surface of the edge skin 13, when the supporting plate supports against the edge skin 13, the supporting plate can be fully contacted with the arc surface of the edge skin 13, the contact part of the supporting plate and the edge skin 13 is designed smoothly, or a buffer pad is additionally arranged on the inner surface of the supporting plate, which is contacted with the edge skin 13. The supporting plate is used for supporting the bottom of the edge skin 13, and further, the supporting plate can be a cambered plate matched with the bottom surface of the edge skin 13. In other embodiments, the chord edge of the arched plate as the supporting plate can be additionally provided with a bump so as to increase the contact area with the bottom surface of the edge skin 13.

The telescopic member 53 may be, for example, a cylinder with a telescopic rod, wherein the telescopic rod may be connected to the bearing plate in the jacking member 51 by a connection structure, and the cylinder may drive the telescopic rod to move the jacking member 51 in a telescopic manner. Here, the telescopic movement of the lifting member 51 includes a telescopic movement of the lifting member and an extending movement of the lifting member, wherein the telescopic movement of the lifting member 51 specifically means that the cylinder drives the telescopic rod to retract to drive the lifting member 51 away from the edge skin 13, and the extending movement of the lifting member specifically means that the cylinder drives the telescopic rod to extend to drive the lifting member 51 to be close to the edge skin 13. Of course, other implementations of the aforementioned telescopic member 53 may be adopted, for example, the telescopic member may also be a servo motor with a screw, where the screw is connected to the jack-up member, and the servo motor drives the screw to rotate to drive the connected jack-up member to perform telescopic motion, for example, drives the screw to rotate forward to drive the jack-up member to perform telescopic motion and drives the screw to rotate reversely to drive the jack-up member to perform telescopic motion, or drives the screw to rotate forward to drive the jack-up member to perform telescopic motion and drives the screw to rotate reversely to drive the jack-up member to perform telescopic motion.

In practical application, in the initial state, the telescopic rod drives the jacking member 51 to be in the contracted state; the wire cutting unit 33 is driven to descend relative to the machine base 1 so that a cutting wire net formed by each cutting wire segment on the wire frame 333 in the wire cutting unit 33 cuts the silicon rod 10 to be cut in the cutting area in an opening mode until the cutting wire net penetrates through the silicon rod 10 to be cut, complete cutting of the silicon rod 10 to be cut is completed, and the edge skin 13 is formed, and at the moment, the edge skin lifting mechanism 5 descends to the bottom along with the wire cutting unit 33; the cylinder drives the telescopic rod to extend so as to drive the jacking piece 51 to be close to the edge skin 13 until an abutting plate in the jacking piece 51 contacts with the edge skin 13 and abuts against the edge skin 13; subsequently, the wire cutting unit 33 is driven to ascend relative to the machine base 1, the edge skin lifting mechanism 5 ascends along with the wire cutting unit 33 to drive the edge skin 13 to ascend relative to the cut silicon rod 12, so that the top end of the edge skin 13 protrudes out of the silicon rod 12 to be cut (see fig. 8 and 9), and when the protruding part of the top end of the edge skin 13 compared with the silicon rod 12 to be cut meets the set condition, the wire cutting unit 33 can be controlled to stop ascending. Thus, the top end of the edge skin 13 can be used as a gripping force part for gripping, so that the edge skin 13 is easier to grip.

In some embodiments, the edge skin lifting mechanism can comprise an absorbing piece and a telescopic component for driving the absorbing piece to make telescopic movement, and the absorbing piece is controlled by the telescopic component to abut against the edge skin and absorb the edge skin. The suction member may further include an abutment plate and a suction member. The abutment plate may be, for example, an arcuate plate adapted to the arcuate surface of the edge skin, which is in sufficient contact with the arcuate surface of the edge skin when the abutment plate abuts the edge skin. The suction element may be, for example, a vacuum chuck, and a plurality of vacuum chucks may be disposed on a contact surface to be contacted with the edge skin in the abutting plate. The telescopic component can be, for example, a cylinder with a telescopic rod or a servo motor with a screw rod, taking the cylinder with the telescopic rod as an example, the telescopic rod can be connected with the abutting plate in the jacking piece through a connecting structure, the cylinder can drive the telescopic rod to shrink so as to drive the abutting plate to be far away from the edge skin, and the cylinder can drive the telescopic rod to stretch so as to drive the abutting plate to be close to the edge skin and absorb the edge skin by the absorption element after the abutting plate is contacted with the edge skin. Subsequently, the linear cutting unit is driven to ascend relative to the machine base, the edge skin lifting mechanism ascends along with the linear cutting unit, and the edge skin can be driven to ascend relative to the cut silicon rod by using the adsorption force, so that the top end of the edge skin protrudes out of the cut silicon rod.

In other embodiments, the staggering mechanism may be, for example, a silicon rod settling mechanism for settling a cut silicon rod to provide for a settling displacement of the cut silicon rod relative to the edge skin such that the top end of the edge skin protrudes from the cut silicon rod. In practical applications, in order to realize the sedimentation of the cut silicon rod, the first silicon rod bearing table or the second silicon rod bearing table for bearing the cut silicon rod is of a lifting design, and the silicon rod sedimentation mechanism may be located below the first silicon rod bearing table or the second silicon rod bearing table, and in a specific implementation, the silicon rod sedimentation mechanism may for example comprise a lifting motor with a lifting column, and the lifting column is controlled by the motor to perform lifting motion. Specifically, the lifting motor drives the lifting column to descend, so that the first silicon rod bearing table or the second silicon rod bearing table can be driven to descend, and the cut silicon rods are settled (at this time, each edge skin is kept stable under the jacking of the corresponding edge skin jacking mechanism), so that the top ends of the cut silicon rods are concave at the top ends of the edge skins, namely, the top ends of the edge skins are protruded out of the cut silicon rods.

The edge skin 13 and the cut silicon rod 12 can be staggered by using the staggering mechanism, so that the follow-up unloading of the edge skin 13 is facilitated. In one embodiment, after the edge skin 13 and the cut silicon rod 12 are offset from each other, since the top end of the edge skin 13 protrudes from the cut silicon rod 12, the top and bottom ends of the edge skin 13 provide points of engagement, at which time the edge skin 13 may be grasped manually by an operator or with corresponding assistance and unloaded. However, in this embodiment, although the offset mechanism is used to offset the edge skin 13 and the cut silicon rod 12 from each other, a better grip is provided for the edge skin 13 to facilitate the unloading operation, overall the unloading operation is still low in efficiency, and the risk of damage to the cut silicon rod 12 caused by collision of the edge skin 13 with the cut silicon rod 12 during the handling process cannot be avoided.

In view of the above, the edge skin unloading device provided by the silicon rod opening apparatus of the present application may further include: and the clamping and transferring mechanism is used for separating the edge skin from the cut silicon rod and unloading the separated edge skin. Taking fig. 2 as an example, the edge skin unloading device of the silicon rod squaring device further comprises a clamping and transferring mechanism 6 for clamping the top end of the edge skin 13, pulling up the edge skin 13 to separate from the silicon rod 12 to be cut, and transferring the edge skin 13 to an edge skin unloading area. In practical applications, the clamping and transferring mechanism 6 further comprises: the device comprises a Z-direction movement mechanism, a second X-direction movement mechanism and an edge skin clamping mechanism which moves on the Z-direction movement mechanism and the second X-direction movement mechanism, wherein the Z-direction movement mechanism can provide movement of the edge skin clamping mechanism along the Z direction, and the second X-direction movement mechanism can provide movement of the edge skin clamping mechanism along the X direction. As shown in fig. 2, the clamping and transferring mechanism 6 includes a sliding seat 61, a Z-direction moving mechanism is provided on the sliding seat 61, a side skin clamping mechanism 63 moves along the Z-direction by using the Z-direction moving mechanism, a second X-direction moving mechanism is arranged on the mounting structure of the machine base 1, and the sliding seat 61 and the side skin clamping mechanism 63 thereon move along the X-direction by using the second X-direction moving mechanism.

The Z-direction movement mechanism may further comprise: z-direction guide rail, Z-direction slider, and Z-direction drive source. As shown in fig. 2, the Z-direction guide rail 300 is laid on the slide 61, and the Z-direction slider is provided on the side skin holding mechanism 63 and is adapted to the corresponding Z-direction guide rail 300, and the Z-direction driving source may be, for example, a Z-direction lifting motor or a Z-direction lifting cylinder. In practical applications, to enable the edge skin gripping mechanism 63 to stably move up and down on the slide 61, a dual-rail design may be adopted, that is, two Z-rails 300 are adopted, and the two Z-rails 300 are disposed in parallel along the Z-direction. In this way, the edge skin gripping mechanism 63 is driven by the Z-direction driving source to move up and down along the Z-direction guide rail.

The second X-direction movement mechanism may further include: the first X-direction guide rail, the first X-direction slider and the first X-direction driving source. As shown in fig. 2, the second X-direction guide rail 200 is laid on the mounting structure of the base 1, and the second X-direction slider is disposed on the slide 61 and is adapted to the corresponding second X-direction guide rail 200, and the second X-direction driving source may be, for example, an X-direction motor or an X-direction cylinder. In practical applications, in order to enable the slide 61 to move stably along the X-direction, a dual-rail design may be adopted, that is, two second X-direction rails 200 are adopted, and the two second X-direction rails 200 are disposed in parallel along the X-direction. In this way, the slide 61 and the side skin gripping means 63 thereon are driven by the second X-direction drive source to move in the X-direction along the second X-direction guide rail 200. In fig. 2, the second X-direction guide rail 200 of the second X-direction movement mechanism is integrated with the first X-direction guide rail 200 of the first X-direction movement mechanism, but not limited thereto, and in other embodiments, the second X-direction guide rail and the first X-direction guide rail may be independent guide rail structures.

The side skin gripping means 63 may further comprise: the lifting driving structure 62 is movably arranged, and the clamping assembly 64 is arranged at the bottom of the lifting driving structure 62, and the clamping assembly 64 is matched with the side leather 13 and used for clamping each side leather 13. In the Z direction, on the one hand, the lifting driving structure 62 is connected to the slider in the Z direction movement mechanism through a mounting seat, so that the lifting driving structure 62 can be driven by the Z direction driving source to move up and down. On the other hand, for the inside of the edge skin holding mechanism 63, the lifting driving structure 62 may be, for example, a lifting cylinder with a lifting rod, where the lifting rod is connected to the holding assembly 64, and thus, the lifting cylinder may be used to control the lifting rod to stretch to drive the holding assembly 64 to move up and down.

Referring to FIG. 10, a schematic diagram of the clamping assembly 64 of FIG. 2 is shown in one embodiment. As shown in connection with fig. 2 and 10, the clamping assembly 64 further includes: a clamping body 642 and a plurality of clamping members 744 provided at the periphery of the clamping body 642.

The clamping body 642 is configured to be inserted into a space defined by the plurality of side panels 13. In practical application, the clamping assembly 64 is further provided with a clamping bracket connected to the lifting driving structure 62, and a clamping main body 642 is disposed at the center of the clamping bracket and is used for penetrating into a space surrounded by a plurality of side skins. Since the silicon rod needs to be cut into a rectangular-like section from an initial circular section (the wire cutting net in the wire cutting unit 33 is in a "well" shape), four side skins 13 are formed after the cutting operation of the silicon rod to be cut, and thus, the space surrounded by the four side skins 13 into which the clamping body 642 is inserted is also a rectangular space, the clamping body 642 may be a rectangular pillar stand with a rectangular section, for example.

Further, a penetration structure 646 may be provided at the top end of the clamp body 642 (the top end faces the silicon rod bearing table 21 located at the cutting region). The structure of the penetrating structure 646 may be, for example, a polygonal pyramid, a truncated cone, a cone, or a hemisphere, and the size of the penetrating structure 646 is slightly smaller than that of the clamping body 642 itself, and the penetrating structure 646 may further smoothly transition with the clamping body 642. In this way, in practical applications, the penetrating structure 646 is more beneficial for the clamping body 642 to penetrate into the space surrounded by the top ends of the silicon rods 12 to be cut in each lifted edge skin 13, so that the clamping assembly 64 can be adapted to silicon rods with different product specifications, and problems of chips, subsequent cleaning and the like caused by collision of the clamping body 642 and the top ends of the protruding edge skins due to space mismatch can be avoided.

The clamping member 644 is disposed at the periphery of the clamping body 642, and a clamping space for clamping the edge skin 13 is formed between the clamping member 644 and the clamping body 642. The clamping members 644 may be clamping jaws corresponding to the side skin 13, for example, because the silicon rod needs to be cut into a rectangular-like section from an initial circular section, four arched side skins are formed after the silicon rod to be cut is subjected to the squaring cutting operation, and therefore, the number of the clamping jaws corresponds to four. The location of the clamping jaw in contact with the edge skin 13 is in an arc-shaped structure adapted to the arc-shaped surface of the edge skin 13, so that the clamping jaw can be an arc-shaped clamping plate, for example. However, the present invention is not limited thereto, and the clamping jaw may be, for example, at least two clamping bars disposed in parallel in a vertical manner, which is not described herein. It should be noted that, as described above, in some embodiments, the wire cutting unit 33 of the wire cutting apparatus 3 includes a pair of cutting wheel sets, and the cutting operation performed by using the pair of cutting wheel sets needs to perform two cutting steps, and in such embodiments, the number of the clamping members may be two, for example, and the two clamping members are disposed opposite to each other. Performing a first squaring and cutting step to form two side skins, clamping the two side skins formed at the corresponding positions by using two clamping pieces, and transferring the side skins out through the Z-direction movement mechanism and the second X-direction movement mechanism; again adjusting the cutting position of the silicon rod to be cut (for example, rotated by 90 °); and performing a second squaring and cutting step to form two side skins, clamping the two side skins formed at the corresponding positions by using two clamping pieces, and transferring the side skins out through the Z-direction movement mechanism and the second X-direction movement mechanism.

The clamping member 644 can be, for example, a movable type, and can perform a folding and unfolding action to move closer to or away from the clamping body 642, so as to adjust the clamping space between the clamping member and the clamping body 642. In addition, the clamping assembly 64 may further be configured with a folding driving mechanism for each clamping member 644, where the folding driving mechanism is disposed on the clamping bracket and connected to the corresponding clamping member 644, and is used for driving the clamping member 644 to perform a folding action so as to cooperate with the clamping main body 642 to clamp the corresponding edge skin 13. The opening and closing driving mechanism may be, for example, an air cylinder 654 with a telescopic rod 653, where the telescopic rod 653 may be connected to the clamping member 644 through a connection structure, and the air cylinder 654 may drive the telescopic rod 653 to drive the clamping member 644 to perform telescopic motion. Here, the telescopic movement of the holder 644 includes a telescopic movement of the holder and an extending movement of the holder, wherein the telescopic movement of the holder specifically means that the cylinder 654 drives the telescopic rod 653 to be contracted to drive the holder 644 to be close to the holder main body 642, the holding space between the holder 644 and the holder main body 642 is reduced, and the extending movement of the holder specifically means that the cylinder 654 drives the telescopic rod 653 to be extended to drive the holder 644 to be far away from the holder main body 642, and the holding space between the holder 644 and the holder main body 642 is increased. To allow the clamp 644 to be stably telescopic to the clamp body 642, a dual-rod design may be adopted, i.e., two telescopic rods 653 are adopted in parallel. Of course, other implementation manners may be adopted in the opening and closing driving mechanism, for example, the opening and closing driving mechanism may also be a servo motor with a screw, the screw is connected to the clamping member, the screw is driven by the servo motor to rotate so as to drive the connected clamping member to perform telescopic motion, for example, the screw is driven to rotate forward to drive the clamping member to perform telescopic motion and the screw is driven to rotate reversely to drive the clamping member to perform stretching motion, or the screw is driven to rotate forward to drive the clamping member to perform stretching motion and the screw is driven to rotate reversely to drive the clamping member to perform telescopic motion.

Referring to FIG. 11, a schematic diagram of the clamping assembly 64 of FIG. 2 is shown in another embodiment. As shown in connection with fig. 13 and 17, the clamping assembly 64 further includes: a clamping body 641 and a plurality of clamping members 643 disposed on the periphery of the clamping body 641.

The clamping body 641 is used for penetrating into a space surrounded by the plurality of side skins 13. In practical application, the clamping assembly 64 is further provided with a clamping bracket connected to the lifting driving structure 62, and a clamping main body 641 is disposed at the center of the clamping bracket for penetrating into a space surrounded by a plurality of side skins. The clamp body 641 may be, for example, a rectangular post having a rectangular cross section.

Further, a penetration structure 645 may be provided at the tip of the clamp body 641, which is directed toward the rod-carrying table 21 located at the cutting zone. The structure of the penetrating structure 645 may be, for example, a polygonal pyramid, a truncated cone, a hemisphere, or the like, and the penetrating structure 645 may have a slightly smaller size than the clamping body 641 itself, and the penetrating structure 645 may further smoothly transition with the clamping body 641.

The clamping piece 643 is disposed at the periphery of the clamping body 641, and a clamping space for clamping the edge skin 13 is formed between the clamping piece 643 and the clamping body 641. The clamping piece 643 may be, for example, clamping jaws corresponding to the side skin 13, and since the silicon rod needs to be cut into a rectangular-like section from an initial circular section, four arched side skins are formed after the silicon rod to be cut is subjected to the squaring cutting operation, and therefore, the number of clamping jaws corresponds to four. The location of the clamping jaw in contact with the edge skin 13 is in an arc-shaped structure adapted to the arc-shaped surface of the edge skin 13, so that the clamping jaw can be an arc-shaped clamping plate, for example. However, the present invention is not limited thereto, and the clamping jaw may be, for example, at least two clamping bars arranged in parallel in a vertical manner, which is not described herein. It should be noted that, as described above, in some embodiments, the wire cutting unit 33 of the wire cutting apparatus 3 includes a pair of cutting wheel sets, and the cutting operation performed by using the pair of cutting wheel sets needs to perform two cutting steps, and in such embodiments, the number of the clamping members may be two, for example, and the two clamping members are disposed opposite to each other. Performing a first squaring and cutting step to form two side skins, clamping the two side skins formed at the corresponding positions by using two clamping pieces, and transferring the side skins out through the Z-direction movement mechanism and the second X-direction movement mechanism; again adjusting the cutting position of the silicon rod to be cut (for example, rotated by 90 °); and performing a second squaring and cutting step to form two side skins, clamping the two side skins formed at the corresponding positions by using two clamping pieces, and transferring the side skins out through the Z-direction movement mechanism and the second X-direction movement mechanism.

The clamping member 643 can be, for example, a movable type design, and can perform a folding and unfolding action to approach or separate from the clamping body 641, so as to adjust the clamping space between the clamping body 641 and the clamping body 641.

With continued reference to fig. 17, the clamping member 643 is pivotally connected to the clamping body 641 or the clamping bracket through a connecting structure, and the connecting structure is further provided with a pressure-bearing portion 651. In addition, the clamping assembly 64 is further configured with a folding driving mechanism for each clamping piece 643, and the folding driving mechanism is used for driving the clamping piece 643 to perform folding action. The opening and closing driving mechanism may be, for example, a cylinder with a telescopic rod, wherein the end of the telescopic rod is provided with a pressing portion 652 matched with the pressure-bearing portion 651, and the pressing portion 652 is abutted against the pressure-bearing portion 651. The cylinder can drive the telescopic rod to drive the pressing part to do telescopic motion, and the clamping piece 643 is driven to do opening and closing actions through the cooperation of the pressing part 652 and the pressure-bearing part 651. Specifically: in the initial state, the holder 643 is in an outwardly expanded state. When the cylinder drives the telescopic rod to extend, the pressing portion 652 on the telescopic rod acts on the pressure-bearing portion 651 on the clamping member 643, and the clamping member 643 is pressed to pivot (i.e., retract) toward the clamping body 641, thereby reducing the clamping space between the clamping member 643 and the clamping body 641. When the cylinder drives the telescopic rod to retract, the pressing part on the telescopic rod releases the pressing force of the pressing part 651 on the clamping piece 643, the clamping piece 643 rotates away from the clamping main body 641 to return to the initial state, and the clamping space between the clamping piece 643 and the clamping main body 641 is increased. Moreover, the pressure-bearing portion 651 and the pressing portion 652 may adopt an adaptive wedge structure, so as to realize that the clamping member 643 may perform a smooth and steady opening and closing operation.

Of course, other variations of the clamping assembly 64 are possible. For example, in one embodiment, the clamping assembly may comprise: the first clamping piece and the second clamping piece form a clamping space for clamping the side leather between the first clamping piece and the second clamping piece. The second clamping piece is located on the inner side and corresponds to the cutting surface of the side skin, and the first clamping piece is located on the outer side and corresponds to the outer surface of the side skin. In this embodiment, since the silicon rod needs to be cut into a rectangular-like section from an initial circular section, four arc side skins parallel to each other are cut along the length direction of the silicon rod, and therefore, the number of the first clamping pieces and the second clamping pieces is four, and the first clamping pieces may be, for example, arc clamping plates adapted to the arc surfaces of the side skins. In addition, the clamping assembly can further comprise a driving device for driving the first clamping piece and/or the second clamping piece to perform opening and closing actions. In particular, in one case, the second clamping member of the clamping assembly may be of a fixed design and the first clamping member of the clamping assembly may be of a movable design, so that the clamping assembly further includes a first driving device for driving the first clamping member to perform a stretching motion toward the second clamping member so as to perform a clamping motion in cooperation with the second clamping member. In another aspect, the first clamping member of the clamping assembly may be of a fixed design and the second clamping member of a movable design, so that the clamping assembly further includes a second driving device for driving the second clamping member to perform a stretching motion toward the first clamping member to perform a clamping motion in cooperation with the first clamping member. In still another aspect, the first clamping member and the second clamping member in the clamping assembly are both of a movable design, so that the clamping assembly further includes a first driving device corresponding to the first clamping member and a second driving device corresponding to the second clamping member, wherein the first driving device is used for driving the first clamping member to perform a stretching motion towards the second clamping member, and the second driving device is used for driving the second clamping member to perform a stretching motion towards the first clamping member, so that the first clamping member and the second clamping member cooperate to perform a clamping motion.

By utilizing the clamping and transferring mechanism disclosed by the application, the edge skin formed by the cutting operation is clamped and then lifted (see figure 12) until the bottom end of the edge skin is higher than the top end of the cut silicon rod, so that the edge skin is separated from the cut silicon rod (see figure 13), and then the edge skin separated from the cut silicon rod is transferred to an edge skin unloading area (see figure 14), thus, the unloading of the edge skin after the cutting operation is finished, the whole unloading process is automatically realized, the operation is convenient, and the operation efficiency is improved.

It should be noted that, in the process of transferring the edge skin by using the clamping and transferring mechanism, for example, in the case that the edge skin is transferred out of the cutting area by using the clamping and transferring mechanism and the cut silicon rod or the wire cutting unit is not blocked, the wire cutting unit which is suspended originally can be controlled to continue to rise until the wire cutting unit returns to the initial position, so that the next silicon rod cutting operation is performed.

With continued reference to fig. 2, the edge skin unloading device may further include an edge skin conveying structure 7 disposed in the edge skin unloading area for conveying the edge skin transferred by the clamping and transferring mechanism 6. In one embodiment, the edge skin conveying structure 7 may be, for example, a conveyor belt. In practice, the edge skin 13 is transferred from the cutting zone to the edge skin unloading zone by the gripper transferring mechanism 6, and the gripper assembly 64 in the gripper transferring mechanism 6 is released to release the edge skin 13 onto the conveyor belt as the edge skin conveying structure 7, which conveys the edge skin out.

Of course, the side skin formed by the squaring and cutting operation is not limited to the unloading. For example, as shown in fig. 2, the side skin unloading device may include a side skin drum 8 and a side skin conveying structure 7, where the side skin conveying structure 7 may be, for example, a conveyor belt, and the side skin drum 8 is disposed adjacent to a start end of the conveyor belt (e.g., the side skin drum 8 is located beside or directly above the start end of the conveyor belt, etc.). In addition, the bung hole of the edge skin cylinder 8 can be designed to be larger or be a horn mouth, so that the edge skin can be conveniently placed in a barrier-free manner, and the height of the bung arm of the edge skin cylinder 8 is also higher, so that the placed edge skin can be ensured not to topple, and the like. In practical applications, the edge skin cylinder 8 may be designed to be reversible, and by turning the edge skin cylinder 8, each edge skin in the edge skin cylinder 8 is smoothly transferred to the conveyor belt. For example, the bottom of the side skin 8 is provided with a turnover driving mechanism, which may include a turnover plate, a rotation shaft, and a turnover driving source (e.g., a turnover motor or a turnover cylinder, etc.). Therefore, after the edge skin is transferred into the edge skin cylinder 8 by the clamping and transferring mechanism through the cutting area (see fig. 15), the edge skin cylinder 8 is turned over to drive the edge skin in the cylinder to be transferred onto the conveying belt (see fig. 16), and the edge skin is conveyed out by the conveying belt. In addition, in other embodiments, the edge skin unloading device may also only include an edge skin cylinder, where the edge skin cylinder is disposed in the edge skin unloading area. Therefore, after the edge skin is transferred into the edge skin cylinder from the cutting area by the clamping and transferring mechanism, the edge skin can be taken out from the edge skin cylinder by an operator.

It should be added that the silicon rod cutting apparatus of the present application may further comprise a silicon rod cleaning device, which may be disposed on the stand and located at the waiting area, for cleaning and cleaning the cut silicon rods 12. In general, in the silicon rod cleaning apparatus, the silicon rod 10 to be cut is formed into the cut silicon rod 12 after the squaring and cutting operation, and cutting chips generated during the squaring and cutting operation are attached to the surface of the cut silicon rod 12, so that the cut silicon rod 12 needs to be cleaned as necessary. Generally, the silicon rod cleaning apparatus includes a cleaning brush head and a cleaning liquid spraying device cooperating with the cleaning brush head, and during cleaning, the cleaning liquid spraying device sprays cleaning liquid (e.g., pure water) against the cut silicon rod 12, and at the same time, the cleaning brush head (preferably a rotary brush head) is driven by a motor to act on the cut silicon rod 12 to complete the cleaning operation.

The application also discloses a silicon rod squaring method which is used for squaring and cutting the silicon rod. The silicon rod squaring method is applied to silicon rod squaring equipment, and the silicon rod squaring equipment comprises a machine base, a silicon rod bearing device, a wire cutting device and an edge skin unloading device.

Referring to fig. 17, a flow chart of the method for developing a silicon rod according to the present application is shown. As shown in fig. 17, the silicon rod opening method includes the following steps:

step S11, carrying a silicon rod to be cut.

In practical application, the silicon rod squaring device comprises a silicon rod bearing device and a silicon rod transferring device adjacent to the silicon rod bearing device, wherein the silicon rod bearing device can comprise a silicon rod bearing table and a silicon rod pushing mechanism corresponding to the silicon rod bearing table, and the silicon rod transferring device comprises a reversing carrier with a silicon rod clamp and a reversing driving mechanism for driving the reversing carrier to do reversing motion. The specific structure of the silicon rod carrying device and the silicon rod transferring device can be referred to the previous description, and will not be repeated here.

In step S11, carrying the silicon rod to be cut may specifically include: the silicon rod transferring device is used for carrying out the feeding operation of the silicon rod to be cut, the silicon rod to be cut is clamped by a silicon rod clamp in a loading and unloading area, and then the reversing driving mechanism drives the reversing carrier to perform reversing movement, the silicon rod clamp is converted from the loading and unloading area to a waiting area, the silicon rod to be cut is released, and the silicon rod to be cut is placed on a silicon rod bearing table in the waiting area; and the silicon rod jacking mechanism in the silicon rod bearing device is used for jacking the silicon rod to be cut, namely, the lifting driving structure is used for driving the compression block to descend so as to jack the top end of the silicon rod to be cut. Of course, in practical application, before the silicon rod pushing mechanism is used for pushing, measurement, position adjustment and the like can be performed on the silicon rod to be cut on the silicon rod bearing table.

And S13, squaring and cutting the silicon rod to be cut.

In practical applications, in step S13, the squaring cutting of the silicon rod to be cut is performed by a wire cutting device in the silicon rod squaring apparatus.

The wire cutting device includes: the wire cutting support of locating on the frame and locate at least wire cutting unit on the wire cutting support with liftable, wherein, the wire cutting unit is corresponding to the cutting district, includes at least: the wire cutting device comprises a wire frame arranged on the wire cutting support, a plurality of cutting wheels arranged on the wire frame and cutting wires, wherein the cutting wires are sequentially wound on the cutting wheels to form a plurality of cutting wire segments, and the cutting wire segments form a cutting wire net.

In step S13, the wire cutting support in the wire cutting device is driven to descend relative to the machine base, and the wire cutting net in the wire cutting unit of the wire cutting device performs squaring cutting on the silicon rod to be cut carried by the silicon rod carrying table in the cutting area until the wire cutting net penetrates through the silicon rod to be cut, thereby completing squaring cutting on the silicon rod to be cut and forming a cut silicon rod (silicon square body) and a side skin.

And S15, unloading the edge skin generated after the cutting.

Referring to fig. 18, a flowchart of the refinement step of step S15 is shown. As shown in fig. 18, step S15 may further include the steps of:

And step S151, driving the edge skin and the cut silicon rod to perform relative lifting displacement, so that the top end of the edge skin protrudes out of the cut silicon rod.

Thus, in practice, the skin unloading process may include: and providing the edge leather clamping mechanism to move to an edge leather unloading area along the X direction by the second X-direction movement mechanism, releasing the clamping component in the edge leather clamping mechanism, and placing the edge leather into the edge leather cylinder.

In some embodiments, the side skin discharge device may further comprise a side skin cartridge and a side skin conveying structure, wherein the side skin cartridge may be of a reversible design, and the side skin conveying structure may be, for example, a conveyor belt. Thus, in practice, the skin unloading process may include: providing the edge leather clamping mechanism to move to an edge leather unloading area along the X direction by the second X direction movement mechanism, releasing a clamping component in the edge leather clamping mechanism, and placing the edge leather into the edge leather barrel; the edge leather cylinder is turned over to drive the edge leather in the cylinder to be transferred onto the conveying belt, and the conveying belt conveys the edge leather out.
