The working principle of the slicing machine is that after the square rod is bonded to a crystal holder, the square rod is sliced by a wire saw cutting manner of a diamond wire net of the slicing machine (the silicon rod is fed along the radial direction, and the wire net reciprocates between adjacent cutting rollers) to produce a silicon wafer. One complete slicing operation of the wire net is referred to as one cutting operation of the slicing machine.

[0006] Through such a structure, the feeding and discharging operation of the workpiece can be realized by the movement of the transfer mechanism relative to the base body.

[0017] In a possible implementation of the feeding and discharging device of the slicing machine, the connecting assembly comprises a first connecting component arranged on the top plate assembly and a second connecting component connected to the first connecting component, and the water collecting tray is arranged on the second connecting component.

[0018] Through the above configuration, possible structural forms of the connecting assembly are provided.

[0019] In a possible implementation of the feeding and discharging device of the slicing machine, the second connecting component is connected to the first connecting component in an adjustable manner.

[0020] Through the above configuration, the relative position of the water collecting tray relative to the top plate assembly can be flexibly adjusted.

[0021] In a possible implementation, a plurality of mounting positions are arranged on the first connecting component, and the second connecting component can be arranged on at least one of the plurality of mounting positions.

[0057] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0059] In addition, it needs to be explained that, in the description of the utility model, unless another explicit provision and limitation, the term "mount", "set", "connect" should be broad understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be direct connection, also can be indirect connection through the intermediate medium, also can be two element internal communication. For the person skilled in the art, the specific meaning of the above-mentioned term in the utility model can be understood according to the specific circumstances.

[0060] In addition, in order to better illustrate the utility model, a large number of specific details are given in the specific embodiments below, and the person skilled in the art should understand that the utility model can also be implemented without certain specific details. In some examples, the principle of slicer and the like is not described in detail, so as to highlight the main idea of the utility model. The utility model will be described below with reference to all or part of the drawings. Figures 1 to 7

[0061] The slicer usually includes a frame, the frame is formed with a cutting chamber, a cutting mechanism (the cutting mechanism is removed in the drawing) wound with wire mesh is arranged in the cutting chamber, and a feed mechanism can approach or move away from the upper surface of the cutting mechanism in the vertical direction. Exemplarily, the cutting mechanism capable of slicing the silicon rod (square rod) usually includes at least two cutting main rollers (such as two, three, etc., such as three in an inverted triangular distribution in this example). In general, the operation mode of the slicing operation is that after the rod bonding is completed in the bonding workshop (such as the silicon rod 200 to be sliced is fixed at the bottom of the crystal holder 201 to form a crystal rod by bonding in the bonding workshop), the crystal holder is fixed on the feed mechanism, and the wire mesh is reciprocated between the cutting main rollers of the cutting mechanism. By driving the feed mechanism to make the silicon rod approach the wire mesh (such as vertically downward), the silicon rod 200 can be cut by the wire saw to slice the square rod. In general, the feeding and discharging device can be arranged on the front side or the rear side of the slicer, and the silicon rod 200 carried on the crystal holder 201 can reach the position corresponding to the cutting operation in the cutting chamber by the corresponding feeding and discharging device in a manual or automatic conveying manner. As in this example, the feeding and discharging device 100 is arranged on the rear side of the slicer.

[0062] In a possible implementation, the feeding and discharging device 100 mainly includes a base body 1, a transfer mechanism 2 and a driving part 3. As in this example, the base body 1 includes a top plate assembly 11, the transfer mechanism 2 includes a sliding plate assembly 21, and the silicon rod bonded to the crystal holder can be carried on the sliding plate assembly 21, and the sliding plate assembly 21 is suspended below the top plate assembly 11. For example, the top plate assembly 11 is usually fixed on the relatively fixed structure / device / equipment such as a mechanical hand, a robot arranged in the installation area of the slicer.

[0063] ​In a possible implementation, the driving part 3 comprises a driving motor (such as a servo motor, etc.) 31 as a driving component (in addition to the driving motor, the driving component can also be any other form of rotating module, etc.) and a chain transmission assembly 32 as a transmission mechanism (in addition to the chain transmission assembly, the transmission mechanism can also be a screw nut mechanism, a gear and rack mechanism, etc.), wherein the driving motor 31 can provide forward power for the movable part, specifically, the driving motor can drive the movable part to slide in the direction close to the cutting chamber 1 through the chain transmission assembly, so that under the action of the forward power, the slide plate assembly 21 can send the silicon rod 200 carried thereon to the position corresponding to the cutting operation in the cutting chamber 1.

[0064] In a possible implementation, the slide plate assembly 21 is provided with two chain transmission assemblies 32 of substantially the same structure on both sides in the width direction (the direction perpendicular to the forward direction), and the driving motor 31 is substantially arranged at the middle of the two chain transmission assemblies 32 and connected with the two chain transmission assemblies at the same time. Obviously, one driving motor can also be configured for each of the two chain transmission assemblies, and the structures of the two chain transmission assemblies can also be different, such as one being a chain transmission assembly and the other being another form of transmission mechanism, both being another form of transmission mechanism, or only one transmission mechanism (such as a slide rail assembly) being arranged.

[0065] Exemplarily, corresponding to the two chain transmission assemblies 32, the two side portions of the top plate assembly 11 are provided with guide rails 12, the chain transmission assembly 32 comprises a plurality of chain wheels 321 (the aforementioned driving motor 31 is drivingly connected with the first chain wheel 321 in the chain transmission assembly), a transmission chain 322 wound between two adjacent chain wheels, a walking wheel 323 capable of walking along the guide rail 12, and a guide wheel 324, wherein the axis of the guide wheel is perpendicular to the axis of the walking wheel (capable of contacting the side wall of the guide rail) and mainly used for ensuring the stability of walking. Obviously, under the premise that the driving connection between the driving motor and the slide plate assembly can be reliably established, those skilled in the art can flexibly adjust the structural form of the chain transmission assembly according to actual needs, such as omitting the guide wheel, the vertical slide plate assembly directly rolling with the chain, etc.

[0066] In a possible implementation, the base body 1 further comprises a water receiving tray 13 located below the top plate assembly 11, and in the case of carrying the silicon rod to the transfer mechanism, the silicon rod is freely accommodated in the space formed by the top plate assembly 11 and the water receiving tray 13, i.e. the water receiving tray 13 is located below the silicon rod 200. The water receiving tray 13 is mainly used for preventing the phenomenon of cutting liquid, silicon mud, etc. splashing to the lower area during the feeding process.

[0067] In a possible implementation, the water pan 13 is fixed to the top plate assembly 11 through the connecting assembly 14 and substantially forms a frame. The connecting assembly includes a first connecting component 141 and a second connecting component 142 connected to each other, the upper end of the first connecting component 141 is fixedly connected to the top plate assembly 11, and the water pan 13 is arranged at the lower end of the second connecting component 142. Apparently, the first connecting component 141 and the second connecting component 142 can be integrally formed (only including one component), as in the present example, the first connecting component 141 and the second connecting component 142 are substantially in the form of a rod, and the width of the first connecting component 141 is greater than that of the second connecting component. Apparently, those skilled in the art can determine the structure of the first / second connecting component according to actual needs.

[0068] In a possible implementation, the first connecting component 141 is fixedly arranged on the top plate assembly, and the second connecting component 142 is adjustably arranged on the first connecting component 141. As in the present example, the first connecting component is provided with a strip-shaped hole 1411 at a position close to the lower end (the position connected to the second connecting component), and correspondingly, the first connecting component is also provided with a strip-shaped hole at a position close to the upper end. After the relative position is determined in the transverse direction, the first connecting component and the second connecting component can be fixedly connected by means of a fastening screw or the like. In this way, the position of the second connecting component in the horizontal direction can be (micro) adjusted. Apparently, this is only an exemplary description, and those skilled in the art can determine the specific structure, specific dimensions, etc. for realizing the adjustability according to actual needs. For example, a plurality of horizontal strip-shaped holes can be arranged in the height direction, a plurality of vertical strip-shaped holes can be arranged in the horizontal direction, a plurality of mounting holes (such as 4 (two rows and two columns), 6 (two rows and three columns)) can be arranged on the first connecting component, etc. In addition, the aforementioned strip-shaped hole can be arranged on one of the first connecting component and the second connecting component, and the mounting hole corresponding to the fastening screw can be directly arranged on the other.

[0069] In the present example, the first connecting component 141 is fixedly arranged on the top plate assembly by means of a screw or the like fastener, and the water pan is removably arranged on the second connecting component 142. As in the present example, the water pan is provided with an extension end 131 (such as a screw joint arranged on the water pan), and the second connecting component 142 can be hooked to the extension end. In this way, the water pan 13 can be removed at any time, and the cutting fluid, silica mud, etc. in it can be cleaned in time. Apparently, the connection between the two can also be achieved by other means such as clamping, insertion, etc. In addition, the connection between the two can also be achieved by detachable screwing, such as loosening the bolt when cleaning the cutting fluid, silica mud, etc. The water pan can be removed.

[0070] In a possible implementation, the feeding and discharging device 100 comprises a limiting assembly 4 arranged on the base body 1, which can be released from the constraint of the transfer mechanism in the feeding state and established in the non-feeding state, so as to effectively prevent the sliding and displacement of the transfer mechanism in the non-feeding state.

[0071] In a possible implementation, the limiting assembly 4 is arranged on the top plate assembly 11 and comprises a cylinder 41 as a limiting driving part and a pin 42 as a first limiting structure, and correspondingly, a hole as a second limiting structure capable of cooperating with the pin is arranged on any position of the transfer mechanism, such as the sliding plate assembly, and in this example, a flange 22 is arranged on the sliding plate assembly 21, and the pin 42 can be inserted into the flange hole under the driving of the cylinder. Based on this, in the non-feeding state of the transfer mechanism, the cylinder is extended to drive the pin to move downward so as to insert the pin into the hole, and in the feeding state, the cylinder is retracted to drive the pin to move upward so as to move the pin out of the hole, so as to prevent the sliding and displacement of the sliding assembly in the non-feeding state, thereby ensuring the reliability of the feeding and discharging device.

[0072] Obviously, the limiting driving part can also be a power cylinder other than the cylinder, such as an electric cylinder, a hydraulic cylinder or any form of linear module, and the first / second limiting structure can also be a block / slot, a sleeve / axle or other structural forms.

[0073] In addition to establishing / releasing the constraint through the movement in the vertical direction, it can also be in the horizontal direction, for example, the limiting assembly is arranged on the side of the base body, and the first limiting structure can be close to / away from the transfer mechanism by moving in the horizontal plane.

[0074] In addition to establishing / releasing the constraint through the movement of the same mechanism, the switching of the connection mode can also be realized through magnetic adsorption (establishing magnetic adsorption by electrification and releasing magnetic adsorption by power-off), combination of two mechanisms (based on mechanism 1, the connection between the two can be realized, and based on mechanism 2, the non-interference between the two can be realized) and other ways.

[0075] As can be seen, in the preferred embodiment of the present application, the silicon rod carried on the sliding plate assembly is sent into the cutting chamber of the slicing machine by suspending the sliding plate assembly on the top plate assembly and driving the sliding plate assembly to slide along the guide rail of the top plate assembly. Through the arrangement of the limiting assembly, the sliding and displacement of the transfer mechanism in the non-feeding state can be effectively prevented, thereby ensuring the reliability of the feeding and discharging device. In addition, through the arrangement of the water pan, the cleanliness during the feeding and discharging operation is ensured.

[0076] The technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but the person skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. The person skilled in the art can make equivalent changes or replacements to the related technical features without deviating from the principles of the utility model, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
