Description

Technical Field

[0001] The present invention relates to the field of wire cutting technology, and specifically provides a slicing unitized production line, a control method for a slicing unitized production line, a computer-readable storage medium, and a computer device. Background Art

[0002] Taking the hard and brittle material as silicon rod as an example, the equipment for processing it usually includes a cutter for cutting the rod material (round rod) according to the length specification, a squarer for cutting the round rod of a certain length into square rods, a grinder for grinding the square rod (grinding surface and chamfer) (such as usually including rough grinding and fine grinding), and a slicer for slicing the square rod that meets the accuracy standard after grinding. The working principle of the slicer is as follows: after the square rod is bonded to the wafer support, the square rod is sliced ​​by wire saw cutting along the radial direction of the silicon rod through the wire mesh of the cutting machine (the silicon rod is fed along its radial direction, and the wire mesh reciprocates between adjacent cutting rollers) to produce silicon wafers (such as silicon wafers). Each complete slicing operation of the wire mesh is called a one-knife cutting operation of the slicer.

[0003] Taking slicing as an example, the slicing operation of existing slicers is concentrated near the slicing station, and each cutting operation is a stand-alone operation for a single silicon rod. Since each cutting operation usually includes dozens of operation steps and is usually completed by one or two operators, this processing method often has the following problems: the operation of the slicer requires high professionalism and proficiency of the operator, and the large number of steps makes it easy for the operator to make mistakes. Once the operator makes a mistake, it may cause different degrees of cutting abnormalities.

[0004] Taking the photovoltaic industry, one of the application fields of silicon wafers, as an example, with the rapid development of the photovoltaic industry, there will inevitably be a demand for continuous expansion of the aforementioned silicon wafer processing chain including slicing operations. As mentioned above, this will lead to a continuous increase in the gap in operators, which already exists. Therefore, stand-alone products (slicers) corresponding to single-machine operations have gradually been unable to meet market demand. In view of this, after fully studying and analyzing the operation of the slicer, the inventor aims to propose a unitized structural framework that can realize the simultaneous operation of multiple slicers. Summary of the invention

[0005] The present invention aims to provide a production line for slicing unitized operations performed by multiple slicing machines and a method for implementing the unitized operations.

[0006] In a first aspect, the present invention provides a slicing unit production line, which includes: a production line main body; at least one slicer, and the slicer can form an avoidance space; and a transfer mechanism, which includes at least at least one automatic guided vehicle (Automated Guided Vehicle, referred to as AGV), and the at least one AGV can deliver the workpiece to and / or move it out of the slicer through the avoidance space.

[0007] Through such a composition, a possible structural form of a slicing unit production line is given.

[0008] It is understandable that those skilled in the art can determine the structural form and number of the transfer mechanism, the specific way of loading the workpiece onto the transfer mechanism, and the movement of the workpiece by the transfer mechanism and where the workpiece moves, etc., according to actual needs. For example, the transfer mechanism can have one or more degrees of freedom to achieve movement in corresponding directions, the workpiece can be directly or with the help of an intermediate component mounted on the transfer mechanism, the transfer mechanism can achieve loading of the workpiece by means of bonding, abutment, accommodation, etc., and the number of transfer mechanisms and slicers can be one-to-one, one-to-many, or many-to-many.

[0009] It is understandable that those skilled in the art can determine the specific form, orientation and formation method of the avoidance space according to actual needs. For example, it can be formed inside the existing parts of the slicer, between different existing parts, or between the existing parts of the slicer and other newly added parts.

[0010] It is understandable that those skilled in the art can determine the number of slicers and AGVs and the corresponding relationship between the two according to actual needs. In the case where there are multiple slicers, the corresponding relationship between AGV and slicer can be one-to-one, many-to-one, many-to-many, etc. For example, it can be: multiple AGVs are configured for multiple slicers in different areas or routes. Obviously, those skilled in the art can select AGVs of any specifications (such as carrying scale, activity dimension, walking principle, control logic, model, etc.) according to actual needs.

[0011] It is understandable that the transfer tasks of the transfer mechanism for the workpiece in each link can be completed entirely by the AGV, or only part of it can be completed by the ground rail robot. It can be completed by one AGV, or it can be completed by the collaboration of multiple AGVs. Exemplarily, the transfer tasks corresponding to the workpiece include transfers corresponding to paths A, B, and C, wherein the transfer tasks corresponding to path A are completed by the AGV, while the transfer tasks corresponding to paths B and C are completed by other means. Exemplarily, after the workpiece is delivered from path A to a designated position (such as the intersection of path A and path B) by the AGV, the workpiece corresponding to path B is transferred by another robot such as a ceiling rail robot, a truss manipulator, an RGV, or a gripper assembly.

[0019] With such a configuration, it is possible to mount the workpiece on the transfer mechanism through the connection jig.

[0020] It is understandable that those skilled in the art can determine the structural form, number, method of loading the workpiece thereon, and method of configuring the transfer mechanism, etc. of the connection tooling according to actual needs. For example, it can be: the connection tooling includes two, and the workpiece is loaded by approaching the two connection toolings in the vertical direction or the horizontal direction; the connection tooling includes one, and a space capable of accommodating space is formed in the connection tooling; etc.

[0021] For the above-mentioned slicing unit production line, in a possible implementation, the connection tooling includes: a first movable part, which can move in a direction close to / away from a cutting chamber of the slicer, and the first movable part is provided with at least one docking structure that can fix the first movable part to the workpiece.

[0024] In addition, it is understandable that those skilled in the art can determine the structural form, number and specific method of the docking structure to achieve fixed connection with the workpiece according to actual needs. For example, the docking structure can be connected to the original structure of the workpiece (or the original configuration structure of the workpiece) to achieve fixed connection or by adding a structure that matches the docking structure to achieve fixed connection.

For example, the first driving component can be a motor, a power cylinder (such as a pneumatic cylinder, an electric cylinder, a hydraulic cylinder), a rotary module, a linear module, etc. The first driving component can directly drive or indirectly drive the first movable part to move closer to / away from the cutting chamber through transmission components such as a gear set, a gear rack mechanism, a screw nut mechanism, etc.

[0040] Through such a construction, a possible structural form of the connection tooling is provided.

[0041] It is understandable that those skilled in the art can determine the structure, number and specific way of carrying workpieces of the carrying part according to actual needs, such as the carrying part has a static carrying space or can form a dynamic carrying space.

[0042] For the above-mentioned slicing unit production line, in a possible implementation, the carrying part includes a second movable part, the second movable part includes a first part and a second part, and the first part and the second part can generate relative movement in a direction of approaching / moving away from each other to hold the workpiece tightly.

[0043] Through such a configuration, a possible structural form of the mounting part is provided.

[0044] It is understandable that those skilled in the art can determine the structural form of the first / second part, the relative motion mode between the two, and the force generation mode for achieving the motion, etc. according to actual needs. For example, both the first part and the second part can move, or only one of them moves while the other is stationary.

[0045] For the above-mentioned slicing unit production line, in a possible implementation manner, the connection tooling includes: a second driving component, and the second driving component can drive the first part and / or the second part to move.

[0046] This configuration provides a possible way for the second movable part to realize its movement.

[0047] Similar to the aforementioned first driving component, it is understandable that those skilled in the art can determine the structural form of the second driving component and the specific manner in which it drives the first / second part to achieve relative motion therebetween according to actual needs.

[0146] The preferred embodiments of the present invention are 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 invention and are not intended to limit the protection scope of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0148] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0149] In addition, in order to better illustrate the present invention, many specific details are given in the following specific embodiments. Those skilled in the art should understand that the present invention can also be implemented without certain specific details. In some examples, the principles of slicers, AGVs, etc., which are well known to those skilled in the art, are not described in detail in order to highlight the main purpose of the present invention. Figures 1 to 17 The present invention is described in whole or in part.

[0150] As a type of wire cutting machine, a slicer is mainly used to cut silicon rods (usually called square rods) with grinding accuracy that meets the standard using a wire mesh composed of cutting wires (such as diamond wires, etc.) to obtain silicon wafers. Under normal circumstances, the slicing operation is as follows: after the stick gluing is completed in a gluing workshop (the square rod to be sliced ​​is glued to the crystal tray), the crystal tray is fixed on the feed mechanism, and during the reciprocating motion of the wire mesh wound on the cutting main roller of the cutting mechanism, the feed mechanism drives the silicon rod close to the wire mesh, and the wire mesh can slice the square rod by wire sawing. For example, the slicer includes a slicer body, and the slicer body is formed with a cutting chamber, and an operating door is respectively provided on the left and right sides of the cutting chamber, and the cutting mechanism is arranged in the cutting chamber. In this example, the cutting mechanism composed of multiple cutting main rollers constructs a single-station structure that can slice a silicon rod in a single operation.

[0151] In a possible embodiment, the present invention provides a slicing production line capable of realizing multi-machine automated production, the production line mainly includes a production line body 1, such as the production line body may include but not limited to necessary work surfaces, terminals that allow manual intervention, parts that must be manually operated, control terminals configured at the work site, collection terminals that can collect the work on site (such as visual signals, sound signals, etc.), central control terminals that can analyze and control the slicing work on site, and reminder terminals that issue reminder information such as voice broadcasts and alarms when necessary. Among them, the slicing production line includes multiple slicing machines 5 (single machines) configured in the production line body, based on which it is expected that multiple slicing machines can simultaneously perform slicing operations on silicon rods to be processed (grinded square rods) or select a part of them to perform slicing operations on silicon rods, such as multiple single machines configured on both sides of the production line body in a removable manner, so that the scale of the production line can be flexibly adjusted and the single machine can be replaced or repaired after removal. In addition, the structural form, slicing operation method and the method of configuring the multiple single machines in the production line body can be the same or different. Exemplarily, the main body of the production line includes multiple areas, wherein a single machine in a certain area is mainly used for processing silicon wafers with more stringent processing requirements, and therefore the single machine corresponding to this area has better processing accuracy.

[0152] In a possible embodiment, the main body of the production line is configured with a loading component and a unloading component, wherein the loading component is connected to a glue workshop or a glue area, such as the silicon rods (bonded to the crystal support) out of the curing warehouse of the glue workshop can be transferred to the loading area 21 corresponding to the loading component by manual and / or automatic operation. For example, the trolley carrying the silicon rods is manually transferred to the loading area. Among them, the unloading component is connected to a degumming workshop or a degumming area, and the degumming workshop is mainly for degumming the silicon rods (in the form of multiple silicon wafers) bonded to the crystal support and completed the slicing operation. Similar to the connection method between the aforementioned glue workshop and the loading operation, the silicon rods corresponding to the unloading area 22 of the unloading component can also be transferred to the degumming workshop or the degumming area by manual and / or automatic operation. For example, the trolley carrying the silicon rods is manually transferred to the degumming workshop or the degumming area. For example, the loading / unloading component generally includes a loading / unloading trolley or an loading / unloading rack.

[0153] In a possible implementation, the aforementioned multiple stand-alone machines share one loading component and one unloading component and use similar loading and unloading control logic for the stand-alone machines. Obviously, the structure of the loading / unloading component can also be adjusted according to actual needs, such as but not limited to: configuring multiple loading components and unloading components for multiple slicers, such as configuring one loading component and unloading component for one or more stand-alone machines according to the orientation, priority, product model, and the properties of the workpiece to be processed (such as the particularity or importance of a batch of products, etc.), illustratively, configuring one loading component and unloading component for multiple stand-alone machines in the same row, and configuring a separate loading component and unloading component for a certain stand-alone machine; multiple stand-alone machines share one loading component and one unloading component, and configuring a separate loading and unloading control logic for one or several stand-alone machines (such as also according to the aforementioned orientation, priority, product model, and the properties of the workpiece to be processed, etc.).

[0154] Taking the example of multiple single machines sharing one group of loading components and one group of unloading components, the production line includes a transfer mechanism, which is mainly used to realize the transfer of silicon rods to be sliced ​​and the cut silicon wafers between the loading component, the slicer and the unloading component, as well as the transfer inside the loading component and the unloading component respectively, such as including the transfer of silicon rods to be sliced ​​between the loading component and the slicer (loading operation), the transfer of cut silicon wafers between the slicer and the unloading component (unloading operation), corresponding operations inside the loading / unloading components, and connection operations such as material picking and unloading in the area between the loading / unloading components and the two.

[0155] In a possible implementation, the transfer mechanism includes a manipulator / robot that can at least walk along the direction between the loading assembly, the unloading assembly, and different slicers. For example, in this embodiment, the manipulator of the transfer mechanism includes multiple AGV3 (six in this example), and the walking logic of the six AGVs is used to realize the movement requirements of the AGVs walking between the loading assembly and the unloading assembly (such as in the length direction corresponding to the slicing unit production line, which can be called the length direction), walking along the direction of moving in / out of the cutting area of ​​the single machine (such as in the width direction corresponding to the slicing unit production line, which can be called the width direction), walking along the vertical direction (such as can be called the longitudinal direction), and walking along other preset paths (such as oblique lines, broken lines, curves, etc.). For example, the corresponding number of single machines can be calculated according to the logical rhythm of the group control system, so that the loading and unloading operations of silicon rods for single machines (moving in / out of the cutting area of ​​the single machine) and production lines (entering the loading area of ​​the production line or moving out of the unloading area of ​​the production line) can be realized by walking multiple AGVs in the corresponding dimensions undertaken by each.

[0156] Based on this, the working mode of the production line is roughly as follows: for example, the group control system can match the appropriate single machine for the silicon rods that need to be processed according to the number of silicon rods that need to be processed, the equipment status of the single machine, the status of the AGV, etc. Based on this, the AGV transports the silicon rods to be processed from the loading area corresponding to the loading assembly to the preset target position that can be connected with the single slicer machine by walking along the aforementioned length direction and width direction according to the control instructions of the group control system. When the silicon rods are delivered to the target position, the group control system reconfirms the status information of the single slicer machine corresponding to the current delivery operation based on equipment management information, such as status information including but not limited to running, debugging, maintenance, fault handling, and standby. When one or more of the multiple AGVs fail, the loading of the current single slicer machine can be achieved by replacing the AGV with manual loading on the front wall of the cutting room as described below, or by replacing the AGV originally configured for the current slicer with other AGVs. After the slicer completes the slicing operation on the silicon rod, the AGV moves the cut silicon wafer including the wafer tray to the unloading area corresponding to the unloading assembly through a walking path similar to the aforementioned loading operation path.

[0157] It can be seen that in the entire slicing unit production line of the present invention, the functional areas mainly include a loading area corresponding to the loading assembly, a slicing area corresponding to multiple slicing machines, a unloading area corresponding to the unloading assembly, and a temporary storage area for temporarily storing the transport vehicle. Based on this, with the help of the AGV walking on the ground, the movement of silicon rods between different slicing machines can be realized.

[0158] In a possible implementation, the production line body is equipped with a connection tool 4, which can be configured on the AGV, and the silicon rods or silicon wafers including the crystal tray can be carried on the connection tool. The connection tool is mainly used to cooperate with the AGV to move the silicon rods including the crystal tray into the cutting area of ​​the single machine to realize the slicing and loading operation for the single machine, or to move the silicon wafers including the crystal tray out of the cutting area of ​​the single machine to realize the slicing and unloading operation for the single machine.

[0159] In a possible embodiment, the connection tool 4 includes a tool base 40 as a mounting carrier and a first movable part 41 and a second movable part arranged on the tool base, such as a manipulator that can carry the connection tool on it by cooperating with the tool base. Exemplarily, the tool base is roughly a plate-like structure. Among them, the first movable part can move along the aforementioned moving in / out direction from the cutting area of ​​the single machine to drive the silicon rod containing the crystal tray to move along the direction, and the second movable part can form a clamping space that holds the silicon rod containing the crystal tray tightly. In this way, on the basis of the silicon rod containing the crystal tray being held tightly by the second movable part, the loading and unloading operations of the silicon rod containing the crystal tray for the single machine can be realized with the help of the first movable part.

[0160] In a possible embodiment, the first movable part 41 generally includes a strip structure arranged along the aforementioned direction of moving in / out from the cutting area of ​​the single machine, and a docking structure capable of cooperating with the crystal tray is arranged or formed on the strip structure along its length direction, so as to achieve the fixed connection between the first movable part and the operating end of the crystal tray by means of the docking structure. Exemplarily, the docking structure is an extension end 411 extending downward from the strip structure, and the extension end can cooperate with the handle at the tail end of the crystal tray as an operating end to achieve the fixed connection between the first movable part and the crystal tray. In this way, under the drive of the servo motor, the strip structure can slide freely in the groove on the upper surface of the crystal tray, and the robot drives the connection tooling to move downward / upward, so that the extension end can cooperate with the handle at the tail end of the crystal tray to clamp the crystal tray or release the cooperation so that the strip structure releases the crystal tray. As in the present invention, two extension ends are respectively arranged at the positions of the two ends of the strip structure.

[0161] For example, if the first movable part includes a first servo motor 412, the first servo motor drives the strip structure to move in / out of the cutting area of ​​the single machine through a first screw nut mechanism 413. For example, in order to ensure that the movement of the first movable part is more stable, a first linear guide rail (not shown) can be arranged on the second movable part along the direction of the first movable part. For example, in this example, a first linear guide rail is arranged on both sides of the strip structure, and accordingly, a slide groove or slide hole capable of cooperating with the linear guide rail is arranged at the end of the strip structure.

[0162] In a possible embodiment, the second movable part includes a first part 421 and a second part 422 that are arranged relatively to each other, and the workpiece is clamped or loosened by moving the first part and / or the second part in a direction of approaching / moving away from each other. For example, if the second movable part is configured with a second servo motor 423, the second servo motor is connected to a second screw nut mechanism 424, and the screw of the second screw nut mechanism includes two thread segments with opposite rotation directions, and nuts adapted to the two thread segments with opposite rotation directions are respectively fixed to the first part and the second part. In this way, the approach / movement between the two parts can be achieved. For example, in order to ensure that the approach / movement movement between the two clamping parts is more stable, a second linear guide rail 425 adapted to the second screw nut mechanism can be configured between the first part and the second part.

[0163] In a possible implementation, in order to ensure that the two clamping parts can clamp the silicon rod containing the crystal support more reliably, the first / second part is formed with a clamping structure on the side close to each other, such as the first / second part has a vertically arranged clamping plate 426 on the part close to each other, and a plurality of protrusions 427 with a buffering function are arranged on the clamping plate, so that the reliability of clamping can be ensured by multi-point clamping. Of course, the protrusion 427 can also be directly fixed on the first part and the second part. As in this example, the first / second part can respectively cooperate with a pair of side parts of the crystal support so as to hold the silicon rod containing the crystal support tightly in the clamping space formed by the first part and the second part. Exemplarily, the clamping plate includes a transverse part and a vertical part, the clamping plate is arranged on the inner side of the vertical part, and reinforcing structures such as reinforcing ribs and reinforcing plates are arranged between the transverse part and the vertical part.

[0164] Main reference Figures 5 to 9 , such as based on the above structure, when the robot delivers the silicon rod (along the length direction and width direction) to the position ( Figure 5 ) After that, the slicing loading process for the cutting room of a single machine mainly includes the following steps:

[0165] S11, make the AGV drive the connecting tooling to move downward, so that the tail end of the strip structure ( Figure 5 The extended end of the strip structure (the right end in FIG) moves downward to hook the handle at the rear end of the crystal tray, thereby achieving fixed connection between the rear end of the strip structure and the silicon rod including the crystal tray.

[0166] S12, the first servo motor 412 drives the strip structure to move (extend) toward the cutting chamber, thereby pushing the entire material (including the silicon rods of the wafer tray) out of the interior of the connecting tooling, and allowing the wafer tray to enter the loading guide rail of the slicer.

[0167] S13, the AGV drives the connection tooling to move upward, so that the extended end of the rear end of the strip structure moves upward and away from the handle at the rear end of the crystal tray. The first servo motor 412 drives the strip structure to move toward the connection tooling (retract), and the AGV drives the connection tooling to move downward, so that the front end of the strip structure ( Figure 5 The extended end of the strip structure (left end in FIG) moves downward so that the extended end at the front end of the strip structure hooks the handle at the rear end of the crystal tray, thereby achieving fixed connection between the front end of the strip structure and the silicon rod including the crystal tray.

[0168] S14, the first servo motor 412 drives the strip structure to move (extend) toward the cutting chamber, so that the strip structure moves again toward the cutting chamber (extends again), thereby pushing the entire material into the cutting chamber of the single machine.

[0169] S15, the AGV drives the connection tool to move upward, so that the extended end of the front end of the strip structure moves upward and leaves the handle at the rear end of the crystal holder. Then the first servo motor 412 drives the strip structure to move (retract) toward the connection tool to the inside of the connection tool.

[0170] Similarly, still based on the above structure, after the robot transports the silicon rod (along the length direction and width direction) to the position ( Fig.10 ) After that, the slicing and unloading process of the cutting room of a single machine mainly refers to Figures 10 to 14 , as in Fig.14 In the state shown, the strip structure moves away from the cutting chamber (gradually entering the interior of the connection tool), thereby pulling the entire material (including the silicon rods on the wafer support) into the space below the connection tool.

[0171] It can be seen that by setting the two protruding ends at the front and rear ends of the strip structure, combined with its cooperation with the crystal support and the corresponding movement mode, the loading and unloading operations of the cutting chamber of a single machine are reliably realized.

[0172] In one possible embodiment, a rear end loading and unloading port can be set on the rear wall of the cutting chamber (close to the feeding position of the unitized production line), and a rear end automatic loading and unloading door can be configured at a position corresponding to the rear end loading and unloading port, and an automatic loading and unloading auxiliary guide rail is set between the crystal support and the rear end automatic loading and unloading door, and the orientation and structure of the automatic loading and unloading auxiliary guide rail and the crystal support can be adapted (such as the height is roughly the same).

[0173] In a possible implementation, a front manual loading and unloading door may be provided on the front wall of the cutting chamber, and a manual loading and unloading auxiliary rail may be provided between the front manual loading and unloading door and the crystal tray, and the orientation and structure of the manual loading and unloading auxiliary rail and the crystal tray may be adapted (such as being roughly flush in height). In this way, with the aid of a loading trolley or other transport equipment, the silicon rods including the crystal tray may be loaded by the forearm through the front manual loading and unloading door and the manual loading and unloading auxiliary rail, or the silicon wafers including the crystal tray may be unloaded after the slicing operation is completed. For example, when the slicer is the smallest unit sold separately, the front manual loading and unloading door may be used to load and unload the slicer that is separated from the slicing unitized production line. Also, in the event of a loading failure in the slicing unitized production line, the front loading and unloading port may be used to load and unload the corresponding single slicer.

[0174] It can be seen that, on the one hand, the aforementioned transfer mechanism, loading / unloading components, and connecting fixtures can be connected in series with multiple slicer machines in the process to realize the unitization and automation of the slicing operation. On the other hand, the traditional manual loading and unloading operation in the scene of the unitization and automation operation can also be realized by manual loading and unloading. In this way, the slicer unit as the basic slicing operation unit in the slicing unitized production line of the present invention is expected to be sold as an element of the product constituting the production line, and can also be sold directly or through acceptable adjustments (such as under the premise of permission, the structural form and configuration orientation of the liquid circuit system, the electric control cabinet, the liquid supply cylinder, etc. are adjusted to an acceptable degree, such as based on the adjustment to a certain extent to remove the constraints set for adapting to the unitized production line scene, and more friendly to adapt to and corresponding to the single machine application scene) in the form of an independent single machine. Therefore, the slicer unit as the basic slicing operation unit in the slicing unitized production line of the present invention can be more friendly to adapt to different application scenes according to actual needs, and has good commercial prospects.

[0175] Embodiment 1:

[0176] Main reference Fig.15In a possible embodiment, the slicer 5 includes a liquid circuit part and an electric control part, in addition to the aforementioned slicer body 51 (including a frame, etc.), a cutting chamber 52, and a cutting mechanism 53 with a cutting line wound thereon to form a cutting line network. The liquid circuit part includes a liquid circuit system 54, a liquid supply cylinder 55, and a cutting liquid adding trolley (not shown). The electric control part mainly includes an electric control cabinet 57. The main functions of the cutting liquid continuously provided by the liquid circuit system include cooling, lubrication, and taking away silicon powder generated at the cutting seam during the slicing operation. In this embodiment, the liquid circuit system includes a separate internal circulation liquid circuit unit 541 and an external circulation liquid circuit unit 542. The electric control cabinet 57 is divided into two according to low pressure and high pressure (such as respectively recorded as a low-voltage electric control cabinet 571 and a high-voltage electric control cabinet 572). The liquid supply cylinder capable of providing and recovering the cutting liquid is arranged at the bottom space of the liquid circuit system.

[0177] In order to adapt to the necessary coordination of the slicer, connecting tooling and transfer mechanism required in the aforementioned slicing unit production line, in this embodiment, the liquid circuit system is roughly arranged on the rear side of the cutting room, and the inner circulation liquid circuit unit and the outer circulation liquid circuit unit are respectively placed at the rear of the cutting room and on both sides. The low-voltage electric control cabinet and the high-voltage electric control cabinet are respectively arranged above the inner circulation liquid circuit unit and the outer circulation liquid circuit unit. In this way, the space between the two electric control cabinets can construct the necessary avoidance space for the loading operation from the rear end (close to the rear loading and unloading port of the slicer) to the front end (close to the AGV layout area), thereby forming an avoidance space that can ensure the automatic loading and unloading operation of the slicer.

[0178] The base of the inner circulation liquid circuit unit rises to reserve space for the liquid supply cylinder, so the liquid supply cylinder can be set below the inner circulation liquid circuit unit. Since the weight of the high-voltage electric control cabinet is heavier than that of the low-voltage electric control cabinet, the base of the outer circulation liquid circuit unit is directly placed on the ground. The cutting fluid filling trolley can be set on the side close to the outer circulation liquid circuit unit.

[0179] It is understandable that, under the premise of ensuring that the slicer can be adapted to the slicing unitized production line, those skilled in the art can flexibly adjust the elements of the slicer and the relative positions between the elements according to the actual situation. For example, the slicer can also be (including but not limited to) constructed in the following ways:

[0180] Embodiment 2:

[0181] Main reference Fig.16 , which is different from the first embodiment, in this embodiment, the liquid system and the electric control cabinet are placed at the rear of the cutting chamber and on both sides, and the liquid supply cylinder is placed between the liquid system and the electric control cabinet. In this way, the space between the liquid system and the electric control cabinet forms an avoidance space that can ensure the automatic loading and unloading operation of the slicer.

[0182] Embodiment three:

[0183] Main reference Fig.17 , which is different from the second embodiment, in this embodiment, the liquid circuit system and the electric control cabinet are arranged on one side behind the cutting chamber of the single slicer in a longitudinal stacking manner, wherein the liquid circuit system is located below the electric control cabinet. The liquid supply cylinder is placed beside the liquid circuit system and the electric control cabinet, and has no spatial overlap with the cutting chamber or has a certain overlap when viewed from the direction of automatic loading and unloading. In this way, since the height of the liquid supply cylinder is relatively low, the configuration of the liquid circuit system and the electric control cabinet will not interfere with the formation of the avoidance space that can ensure the automatic loading and unloading operation of the single slicer.

[0184] Embodiment 4:

[0185] There is also such an embodiment, which is different from the first embodiment in that in this embodiment, the electric control cabinet is adjusted to a suspended wall cabinet, so that the space between the two liquid circuit units of the liquid circuit system forms an avoidance space that can ensure the automatic loading and unloading operation of the slicer. It can be understood that the suspended setting method and setting position of the wall cabinet can be arbitrarily selected according to actual needs.

[0186] In the slicing unitized production line of the present invention, necessary adjustments are made to the single slicer relative to the traditional slicer so that it can be better adapted to the production line. Based on this, through the configuration of a transfer mechanism such as one or more AGVs, the connection between the silicon rod containing the crystal tray before slicing and the silicon wafer containing the crystal tray after slicing can be realized between the loading assembly and the unloading assembly. Through the configuration of the connection tooling, the silicon rod before slicing and the single crystal silicon rod containing the crystal tray after slicing can be flexibly and smoothly connected between the AGV and any single machine. On this basis, by analyzing the operation of the single machine, the operation between the single machine and the AGV, and the operation between the loading assembly and the unloading assembly, the corresponding control logic is given (such as through a group control system including field control and remote central control), and the unitized production of the slicing operation can be realized. On the basis of the unitization of the slicing operation, it is expected to better meet the market development needs of slicing products such as silicon wafers, such as better catering to the development trend of the photovoltaic industry.
