Abstract
Description
Technical Field
[0001] This application relates to the technical field of silicon material processing, and particularly to a workpiece cutting and grinding integrated device. Background Art
[0002] At present, with the increasing attention and development of the society on the utilization of green and renewable energy, the field of photovoltaic solar power generation has received more and more attention. In the field of photovoltaic power generation, ordinary crystalline silicon solar cells are made on high-quality silicon wafers, and such silicon wafers are formed by multi-wire saw cutting and subsequent processing after pulling or casting silicon ingots.
[0003] Taking monocrystalline silicon products as an example, the general production process of existing silicon wafers generally includes the following steps: first, use a silicon rod cutting machine to cut the original long silicon rod to form multiple short silicon rods; after cutting, use a silicon rod squaring machine to square the cut short silicon rods to form square silicon rods with a quasi-rectangular cross-section; then perform grinding operations such as surface grinding and chamfering on the squared silicon rods to make the surface of the silicon rods shaped to meet the corresponding flatness and dimensional tolerance requirements; subsequently, perform slicing operations on the square silicon rods to obtain silicon wafers. The silicon wafers obtained by the slicing operation can be used to manufacture photovoltaic modules, and the photovoltaic modules can convert light energy into electrical energy.
[0004] In order to improve the conversion efficiency of photovoltaic modules, shingled modules have emerged. Shingled modules refer to the series connection of multiple solar cells in a front-to-back overlapping form. There is no gap between the solar cells, and there is no solder strip blocking the solar cells. Therefore, more solar cells can be accommodated under the same area of the module, expanding the effective power generation area. Generally, to obtain silicon wafers for manufacturing shingled modules, silicon rods that can be sliced into silicon wafers need to be manufactured first, and the silicon rods are usually manufactured by re-cutting and grinding the square silicon rods completed in the original process. Most manufacturers will first use cutting equipment and then grinding equipment to obtain the silicon rods, resulting in low efficiency. Therefore, how to provide a device with a simple structure, convenient operation, and capable of quickly and efficiently manufacturing corresponding silicon rods is a technical problem that needs to be solved urgently by those skilled in the art. In particular, designing reasonable working stations for the processing equipment of silicon rods according to each process is an important factor in improving the processing efficiency of silicon rods. Summary of the Invention
[0005] In view of the above-mentioned disadvantages of the related art, the purpose of this application is to provide a workpiece cutting and grinding integrated device to solve the problems of complex structure, inconvenient operation, and low efficiency existing in the existing equipment.

[0007] In summary, the integrated workpiece cutting and grinding equipment provided by the present application integrates a dual-station cutting device and a dual-station grinding device in a parallel manner into one device with a layout of cutting on both sides and grinding on the inside, so as to realize the integrated operation of cutting in half, grinding and chamfering multiple processes of rectangular silicon rods, thereby improving production efficiency; moreover, the present application avoids possible collision of the workpiece during the cutting process by vertically cutting and then separating it in half, thereby improving the quality of the workpiece processing operation; furthermore, the present application also realizes the chamfering operation of different edges of different silicon rods by setting a flippable chamfering device, which not only simplifies the equipment structure but also optimizes the operation sequence; finally, the present application realizes automatic loading and unloading through the cooperation of the first loading and unloading station, the second loading and unloading station and the transport mechanism, thereby further improving work efficiency.

[0026] The following specific embodiments illustrate the implementation manners of the present application. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification.
[0027] In the following description, reference is made to the accompanying drawings, which describe several embodiments of the present application. It should be understood that other embodiments may also be used and mechanical compositions, structures, electricals, and operations may be changed without departing from the spirit and scope of the present disclosure. The following detailed description should not be considered restrictive, and the scope of the embodiments of the present application is only defined by the claims of the published patent. The terms used herein are only for describing specific embodiments and are not intended to limit the present application. Spatially related terms, such as "upper", "lower", "left", "right", "below", "beneath", "lower part", "above", "upper part", etc., may be used in the text to facilitate the description of the relationship between one element or feature shown in the figure and another element or feature.
[0028] Although in some instances the terms first, second, etc. are used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, the first cutting station may be referred to as the second cutting station, and similarly, the second cutting station may be referred to as the first cutting station, without departing from the scope of the various described embodiments. The first cutting station and the second cutting station are both describing a certain cutting station, but unless the context clearly indicates otherwise in other ways, they are not the same cutting station. Similar situations also include the first cutting device and the second cutting device, the first loading and unloading station and the second loading and unloading station, the first grinding station and the second grinding station, the first planar spindle and the second planar spindle, etc.
[0029] As described in the background art, when manufacturing a silicon rod that can be sliced into silicon wafers, the cuboid-shaped silicon rod is usually cut, ground, and chamfered by using a cutting device and a grinding device separately, resulting in complex equipment, inconvenient operation, and low processing efficiency. In view of this, the present application discloses a workpiece cutting and grinding integrated device. By integrating the first and second cutting stations and the first, second, and third grinding stations arranged in parallel into one device, the integrated operation of multiple processes such as halving cutting, grinding, and chamfering of the cuboid-shaped silicon rod is completed, thereby improving the production efficiency and the quality of the product processing operation; by providing a separable and rotatable cutting carrier, the suspension flipping of the workpiece by the workpiece conveying device is avoided, and the workpiece can be more stably supported; by providing a rotatable chamfering device, the chamfering operation of different edges of different silicon rods is realized, simplifying the equipment structure and saving the floor area; through the cooperation of the first loading and unloading station, the second loading and unloading station and the workpiece conveying mechanism, the automatic transfer and automatic loading and unloading are realized, thereby further improving the working efficiency.
[0030] To clarify the definition of directions and the operation mode between different structures, in the embodiments disclosed in the present application, a three-dimensional space defined by a transverse direction (also referred to as the first direction), a longitudinal direction (also referred to as the second direction), and a vertical direction (also referred to as the third direction) is defined. The transverse, longitudinal, and vertical directions are all straight lines and are perpendicular to each other pairwise. For example, the width extension direction of each station is also called the lateral direction and defined as the transverse direction (for example, the direction where X is located in Figure 2 ), the length extension direction of each station is defined as the longitudinal direction (for example, the direction where Y is located in Figure 2 ), and the vertical direction is also called the lifting direction, the plumb line direction, or the up and down direction and defined as the vertical direction (for example, the direction where Z is located in Figure 2 ).
[0031] To clearly illustrate the positional relationship between each device, component, structure, or mechanism in the embodiments of the present application, one side of the initial position where the silicon rod is loaded on the workpiece cutting and grinding integrated device is defined as the proximal or near side, and one side of the workpiece cutting and grinding integrated device where the silicon rod moves from the starting position to the end position when performing a grinding operation at the first grinding station or the second grinding station is defined as the distal or far side. It should be understood that when the silicon rod moves from one side of the workpiece cutting and grinding integrated device to the opposite side to perform a grinding operation at the first grinding station or the second grinding station, the proximal or near side and the distal or far side respectively correspond to the opposite sides of the workpiece cutting and grinding integrated device, and the two are opposite and far away from each other.
[0032] In any of the embodiments provided in the present application, the silicon rod may be, for example, a single crystal silicon rod and a polycrystalline silicon rod. The single crystal silicon rod is a rod-shaped single crystal silicon grown from a melt by a Czochralski method or a floating zone melting method, such as a single crystal silicon rod with a length of approximately 5000 mm (for example, a specification of 5360 mm, etc.) or a single crystal silicon rod with a length of approximately 800 mm, which is commonly seen in silicon rod processing. The polycrystalline silicon rod is a silicon rod in which silicon is precipitated on the surface of a silicon core wire by a precipitation technique such as chemical vapor deposition technology, but is not limited to this.
[0033] The workpiece cutting and grinding integrated equipment described in the present application is suitable for the processing of rectangular silicon rods. For the convenience of description, the rectangular silicon rods are referred to as workpieces below. In an embodiment, the workpiece includes a first specification workpiece and a second specification workpiece. The first specification workpiece refers to a silicon rod with a rectangular cross-section formed by cutting and squaring a silicon rod with a circular cross-section. The quasi-rectangle includes a rectangle with adjacent sides orthogonal or an angle range within a predetermined angle. The second specification workpiece refers to a half rod after the first specification workpiece is cut along the end by a cutting device, and the end refers to the two ends opposite to each other along the length direction of the workpiece axis. It should be understood that the end face of the workpiece refers to the two opposite faces along the length direction of the workpiece, the bottom face of the workpiece refers to the side of the workpiece placed on the processing platform, the top face of the workpiece refers to the side opposite to the bottom face in the vertical direction, and the side elevation of the workpiece refers to the other two faces of the workpiece except the two end faces and the bottom and top faces.
[0034] Before slicing a workpiece, in order to prevent edge collapse and improve the yield of silicon wafers, the workpiece is usually chamfered. Chamfering refers to the process of grinding the edge of the workpiece into a certain slope from one end face to the other end face of the workpiece using a fine grinding wheel with a specific shape.
[0035] In any embodiment of the present application, the workpiece cutting and grinding device is used to process workpieces of a first specification and a workpiece of a second specification, but is not limited thereto. For example, in some examples, the workpiece cutting and grinding device can also be used for other long strips of hard materials.
[0036] See also Figures 1 to 2 , Figure 1 It is a schematic diagram showing the positions of various processing stations in the workpiece cutting and grinding integrated equipment in one embodiment of the present application, Figure 2 This application is displayed in Figure 1 The three-dimensional structure diagram of the workpiece cutting and grinding integrated device in the embodiment shown is as follows. Figures 1 to 2 As shown, the workpiece cutting and grinding integrated equipment of the present application comprises: a machine base 1, a cutting device 2, a main shaft frame 3, and a grinding device 4.
[0037] The workpiece cutting and grinding integrated equipment of the present application is described in detail below.
[0038] The machine base 1 serves as the main component of the workpiece cutting and grinding integrated device, and is used to provide a workpiece processing platform and bear the working components. In practical applications, the machine base is large in size and weight to provide a large mounting surface and a firm stability of the whole machine. It should be understood that the machine base can be used as the seat of different structures or components that perform processing operations in the workpiece cutting and grinding integrated device, and the specific structure of the machine base can be changed based on different functional requirements or structural requirements. In some examples, the machine base includes a fixed structure or a limiting structure such as a base, a column, a frame, etc. for receiving different components in the workpiece cutting and grinding integrated device, which are all the machine bases described in this application. At the same time, in some examples, the machine base can be used as an integrated base, and in some examples, the machine base can include multiple independent bases.
[0039] The machine base has a workpiece processing platform, and the workpiece processing platform can be divided into a plurality of functional areas according to the specific work content of the workpiece processing operation. For example, in some embodiments, the workpiece processing platform includes a cutting area and a grinding area. In some embodiments, the workpiece processing platform includes a cutting area, a grinding area, and a chamfering area. In some embodiments, the workpiece processing platform includes a cutting area, a grinding area, a chamfering area, and a loading and unloading area.
[0040] It should be noted that in each example provided in the present application, the functional location is defined by the travel path and range of the processing device at the functional location. For example, the cutting device of the workpiece cutting and grinding device is located at the cutting location, and the range of the cutting location is the range occupied by the cutting device in the process of completing the cutting operation; similarly, the grinding device of the workpiece cutting and grinding device is located at the grinding location, and the range of the grinding location is the range occupied by the grinding device in the process of completing the grinding operation; the chamfering device of the workpiece cutting and grinding device is located at the chamfering location, and the range of the chamfering location is the range occupied by the chamfering device in the process of completing the chamfering operation. The shape of the workpiece processing platform can be determined based on the machine base, or can be determined based on the processing needs of the machine base and the cutting device, the grinding device, and the chamfering device.
[0041] exist Figures 1 to 2 In the embodiment shown, the machine base 1 is provided with a workpiece processing platform, and the workpiece processing platform is provided with functional areas such as a cutting area, a grinding area, a chamfering area, and a loading and unloading area. A cutting device is provided in the cutting area for cutting the workpiece located in the cutting area. A grinding device is provided in the grinding area for grinding the workpiece located in the grinding area. A chamfering device is provided in the chamfering area for chamfering the workpiece located in the chamfering area.
[0042] In the embodiment described in the present application, the cutting positions are configured as a first cutting station 11 and a second cutting station 12 located on opposite sides of the base 1 and extending longitudinally from the proximal end to the distal end. Figures 1 to 2 As shown, the first cutting station 11 and the second cutting station 12 which are arranged opposite to each other at the outermost sides of the machine base 1 in the transverse direction are located at the left and right sides of the machine base 1 respectively.
[0043] See also Figure 3 , showing that this application is in Figure 2 A schematic diagram of the three-dimensional structure of the workpiece cutting and grinding integrated device in the illustrated embodiment omits the gantry from another perspective. As shown in the figure, the cutting device 2 can be further divided into a first cutting device 21 and a second cutting device 22, the first cutting device 21 can be longitudinally movably arranged on the machine base 1, and is used to cut the first-specification workpiece on the first cutting station 11 into a second-specification workpiece, and the first cutting device 21 is surrounded by a first cutting line, thereby forming a first vertical wire saw, which is used to vertically cut the first-specification workpiece located at the first cutting station 11 in half; correspondingly, the second cutting device 22 can be longitudinally movably arranged on the machine base 1, and is used to cut the first-specification workpiece on the second cutting station 12 into a second-specification workpiece, and the first cutting device 22 is surrounded by a second cutting line, thereby forming a second vertical wire saw, which is used to vertically cut the first-specification workpiece located at the second cutting station 12 in half, so as to separate the cut workpiece into halves before the subsequent grinding operation so that the placement of the workpiece can adapt to the grinding operation.
[0044] In one embodiment, the loading and unloading area is configured as a first loading and unloading station 13 and a second loading and unloading station 14. The first loading and unloading station 13 and the second loading and unloading station 14 are arranged in the longitudinal direction of the machine base 1 and are located in the middle area of the machine base 1 for carrying and transporting workpieces during loading and unloading.
[0045] In one embodiment, the grinding area is configured as a first grinding station 15 and a second grinding station 16, the first grinding station 15 is arranged between the first cutting station 11 and the first loading and unloading station 13, and the second grinding station 16 is arranged between the first loading and unloading station 13 and the second loading and unloading station 14. The grinding device 4 includes a grinding device and a chamfering device. The grinding device is configured as a first grinding device and a second grinding device, and is used to grind the cut surface of the second specification workpiece formed by half cutting at the first cutting station 11 and the second cutting station 12. Figure 3 As shown, the first surface grinding device is arranged at the first grinding station 15, including a first plane spindle 41 and a second plane spindle 42; the second surface grinding device is arranged at the second grinding station 16, including a third plane spindle 43 and a fourth plane spindle 44.
[0046] In one embodiment, the chamfering area is configured as the third grinding station 17. As Figure 3 shown, the third grinding station 17 is arranged between the second loading and unloading station 14 and the second cutting station 12. Correspondingly, the chamfering device is configured as an edge spindle 45. The edge spindle 45 is arranged at the third grinding station 17 and is used for chamfering the second-standard workpieces that have completed surface grinding at the first grinding station 15 and the second grinding station 16.
[0047] To facilitate the erection of the surface grinding device and the chamfering device, the integrated workpiece cutting and grinding equipment includes a spindle support 3. The spindle support 3 is arranged on the machine base 1 and straddles the outside of the first grinding station 15 and the second grinding station 16. Here, the spindle support 3 serves as a carrier for arranging the first planar spindle 41, the second planar spindle 42, the third planar spindle 43, the fourth planar spindle 44, and the edge spindle 45 on the machine base 1. Its specific form can adopt a beam body, a column body, a plate frame, a bracket, etc.
[0048] To facilitate the adjustment of the vertical position of each spindle relative to the workpiece, and further adjust the vertical position of the surface grinding device and the chamfering device relative to the workpiece, the spindle support 3 further includes a vertical guide rail. The vertical guide rail is arranged vertically on the spindle support. Taking the first planar spindle as an example, in one embodiment, the first planar spindle includes a slider, and the spindle support further includes a lifting drive unit. The slider is arranged on the first planar spindle and is adapted to the corresponding vertical guide rail. The lifting drive unit is used to drive the first planar spindle to move up and down along the vertical guide rail.
[0049] In actual applications, to enable the first planar spindle to achieve stable lifting on the spindle support, a double-guide rail design can be adopted, that is, two vertical guide rails are used, and these two vertical guide rails can be arranged in parallel. In addition, the lifting drive unit can further include a lifting lead screw and a lifting motor. Among them, the lifting lead screw is arranged vertically and connected to the first planar spindle, and the lifting motor (the lifting motor can be, for example, a servo motor) is connected to the lifting lead screw. In this way, the lifting motor drives the lifting lead screw to rotate, so as to realize the up and down movement of the first planar spindle along the vertical guide rail. The implementation manner of the lifting drive unit is not limited to this, and other components that can realize driving the first planar spindle to move up and down along the vertical guide rail are still applicable. For example, the lifting drive unit can include a lifting rack, a drive gear meshing with the lifting rack, and a drive motor for driving the drive gear to rotate.
[0050] In another embodiment of the present application, the connection assembly between the spindle support and the vertical guide rail further includes a limit block for restricting the first planar spindle from undergoing excessive displacement during the lifting movement.
[0051] As shown in the example, the second plane main shaft 42, the third plane main shaft 43, the fourth plane main shaft 44, and the edge main shaft 45 may have the same configuration and function as the first plane main shaft 41, which will not be elaborated here and is hereby stated clearly. Figure 3 For the loading and unloading operations at the loading and unloading stations, taking the first loading and unloading station as an example, the first loading and unloading station 13 includes a carrier and a conveyor belt provided on the carrier for loading and unloading workpieces. The conveyor belt may be configured as two rows of roller groups arranged on opposite sides of the carrier. The two rows of roller groups include a plurality of rollers arranged in sequence along the length of the carrier. Each roller can be pivotally connected to the carrier through a bearing block and protrude from the carrier. The rollers in the two rows of roller groups can form a supporting surface for supporting the workpiece. After the workpiece is placed horizontally on the two rows of roller groups of the carrier, the workpiece can be directly pushed by the two rows of roller groups to convey the workpiece and complete the workpiece loading operation.
[0052] In some embodiments, the conveyor belt further includes a workpiece pushing mechanism. By using the workpiece pushing mechanism, the workpiece can be pushed alone or in cooperation with human force to move on the two rows of roller groups. In some embodiments, the workpiece pushing mechanism may also be configured as a chain drive mechanism, including an endless chain, a pushing member provided on the endless chain, and a chain drive unit for the movement of the endless chain. The pushing member may include a pushing block or a pushing rod. The chain drive unit may include a drive gear meshing with the endless chain and a drive motor associated with the drive gear. In practical applications, the drive motor drives the drive gear to rotate, and the drive gear drives the endless chain and the pushing block or pushing rod thereon. The moving pushing block or pushing rod pushes the workpiece to move along the endless chain.
[0053] In some embodiments, in the two rows of roller groups, in the transverse direction, the rollers in the first row of roller groups and the rollers in the second row of roller groups are pairwise opposite to form a roller pair. The two rollers in a roller pair can be associated through a rotating shaft. The workpiece pushing mechanism includes a cascaded chain drive mechanism, including a plurality of cascaded chains and a drive motor. Specifically, the workpiece pushing mechanism is disposed on one side of the two rows of roller groups as the driving side, and each roller in the driving side of each roller pair is configured with a double drive gear. The cascading of all the rollers in the two rows of roller groups is achieved by connecting the adjacent two rollers along the longitudinal direction through a cascaded chain (for example, an endless short chain) sleeved on the corresponding drive rack. The drive motor is also associated with the two rows of roller groups through an endless short chain and a drive gear.
[0054]
[0055] In practical applications, the driving motor drives the driving gear to rotate, drives all the rollers in the two rows of roller sets to roll through the cascading chain, and drives the workpiece to move by means of the frictional force between the rollers and the workpiece. Compared with ordinary chain drive mechanisms, the cascading chain drive mechanism can generate greater power, and all the rollers rotate synchronously, ensuring that the workpiece moves more smoothly and steadily.
[0056] As shown in Figure 3 the example, the second loading and unloading station 14 can have the same configuration and function as the first loading and unloading station 13, which will not be elaborated here and is hereby stated.
[0057] Furthermore, in the workpiece grinding and cutting integrated equipment of the present application, in an alternative embodiment, a cleaning assembly may further be included. The cleaning assembly is arranged on the first loading and unloading station and the second loading and unloading station and is used to perform a cleaning operation on the workpiece that has completed the grinding operation. For the cleaning assembly, after the workpiece has undergone the above-mentioned grinding and chamfering operations, cutting debris generated during the operation will adhere to the surface of the workpiece. Therefore, when necessary, the workpiece needs to be cleaned. Generally, the cleaning assembly includes a cleaning brush head and a cleaning liquid spraying device that cooperates with the cleaning brush head. During cleaning, the cleaning liquid spraying device sprays cleaning liquid onto the workpiece, and at the same time, the cleaning brush head is driven by a motor to act on the workpiece to complete the cleaning operation. In practical applications, the cleaning liquid can be, for example, pure water, and the cleaning brush head can be, for example, a rotary brush head.
[0058] To facilitate the loading and unloading of the workpiece from the first loading and unloading station and the second loading and unloading station using manual or mechanical devices during loading and unloading, a part of the first loading and unloading station 13 and the second loading and unloading station 14 extends longitudinally to the outside of the machine base. That is to say, the area for loading and unloading the workpiece of the first loading and unloading station 13 and the second loading and unloading station 14 protrudes from the machine base, as Figure 1 shown, the longitudinal lengths of the first loading and unloading station 13 and the second loading and unloading station 14 extend beyond the dotted line part of the area where the machine base 1 is located. It should be understood that the lengths by which the first loading and unloading station 13 and the second loading and unloading station 14 protrude from the machine base are greater than or equal to the length of the workpiece, so as to provide sufficient space for the loading and unloading of the workpiece.
[0059] In order to realize the transfer of workpieces at various stations according to the processing procedures, the workpiece cutting and grinding equipment also includes a workpiece transport mechanism 5, which is arranged on the machine base 1 and spans the outer sides of the first cutting station 11 and the second cutting station 12, and is used to transfer the workpiece on the first loading and unloading station 13 and / or the second loading and unloading station 14 to the first cutting station 11 or the second cutting station 12, or transfer the workpiece on the first cutting station 11 or the second cutting station 12 to the first grinding station 15 or the second grinding station 16, or transfer the workpiece on the first grinding station 15 or the second grinding station 16 to the third grinding station 17, or transfer the workpiece processed at the third grinding station 17 to the first loading and unloading station 13 and / or the second loading and unloading station 14.
[0060] See also Figure 4a Combined with Figure 2 ,in, Figure 4a The figure shows a three-dimensional structural diagram of a workpiece transport mechanism in an embodiment of the workpiece cutting and grinding integrated device of the present application. Figure 4a As shown, the piece transport mechanism 5 includes a gantry 51 and a piece transport device 52 , and the gantry 51 spans the outer sides of the first cutting station 11 and the second cutting station 12 .
[0061] See also Figure 4b , shown as this application Figure 4a The schematic diagram of the structure of the transport device in the embodiment shown. Figure 4b As shown, the object transport device 52 includes an object transport base 521 , a mechanical arm 522 , and a suction cup assembly 523 .
[0062] The workpiece carrier 521 is used to realize the lateral movement of the workpiece conveying device 52 on the gantry 51. For this purpose, a laterally extending lateral guide rail 511 is provided on the gantry 51. Correspondingly, a laterally translating slider is provided on the workpiece conveying device 52, and the laterally translating slider is arranged on the workpiece carrier 521 corresponding to the lateral guide rail 511. In some embodiments, the workpiece conveying mechanism 5 further includes a workpiece conveying translation driving unit, and the workpiece conveying translation driving unit may include: a workpiece conveying translation rack, a workpiece conveying translation gear, and a workpiece conveying translation driving motor 524. The workpiece conveying translation rack is arranged laterally on the gantry 51, the workpiece conveying translation gear is arranged on the workpiece carrier 521 and meshes with the workpiece conveying translation rack, and the workpiece conveying translation driving motor 524 is used to drive the workpiece conveying translation gear to rotate so that the associated workpiece carrier 521 moves along the workpiece conveying translation rack, thereby realizing the lateral movement of the workpiece conveying device 52. For example, when the workpiece conveying translation driving motor 524 drives the workpiece conveying translation gear to rotate forward, it drives the workpiece conveying device 52 to move leftward laterally along the workpiece conveying translation rack; when the workpiece conveying translation driving motor 524 drives the workpiece conveying translation gear to rotate reversely, it drives the workpiece conveying device 52 to move rightward laterally along the workpiece conveying translation rack.
[0063] In some embodiments, the workpiece conveying translation driving unit may include a workpiece conveying translation lead screw and a workpiece conveying translation driving motor. The workpiece conveying translation lead screw is arranged laterally and is associated with the workpiece carrier 521, and the workpiece conveying translation driving motor is associated with the workpiece conveying translation lead screw. By driving the workpiece conveying translation lead screw to rotate forward and reversely with the workpiece conveying translation driving motor, the workpiece carrier 521 is driven to move left and right laterally along the lateral guide rail 511, thereby realizing the lateral movement of the workpiece conveying device 52. For example, when the workpiece conveying translation driving motor drives the workpiece conveying translation lead screw to rotate forward, it drives the workpiece conveying device 52 to move leftward laterally along the lateral guide rail 511; when the workpiece conveying translation driving motor drives the workpiece conveying translation lead screw to rotate reversely, it drives the workpiece conveying device 52 to move rightward laterally along the lateral guide rail 511.
[0064] In an embodiment, the workpiece conveying device further includes a first suction cup assembly 523. The first suction cup assembly 523 is fixed to the end of the robotic arm 522 and is used to adsorb the top surface of the workpiece. In one implementation, the first suction cup assembly 523 includes a gas source and a suction cup body. The gas source is connected to the suction cup body through a trachea and is used to control the suction cup body to generate a predetermined pressure to adsorb or release the workpiece. In practical applications, the gas source may be, for example, a vacuum pump.
[0065] To achieve the lifting movement of the first suction cup assembly and thus realize the extraction or placement of the workpiece at the work station, one end of the robotic arm 522 is movably arranged on the workpiece carrier 521, and the other end is fixedly connected to the first suction cup assembly 523. In some embodiments, the workpiece carrier mechanism 5 includes a workpiece carrier lifting drive unit. In some embodiments, the workpiece carrier lifting drive unit may include a workpiece carrier lifting lead screw and a workpiece carrier lifting drive motor 525. The workpiece carrier lifting lead screw is vertically arranged and associated with the workpiece carrier 521, and the workpiece carrier lifting drive motor 525 is associated with the workpiece carrier lifting lead screw. By driving the workpiece carrier lifting lead screw to rotate forward and backward with the workpiece carrier lifting drive motor 525, the length of the robotic arm 522 extending relative to the workpiece carrier 521 is controlled, and thus the lifting movement of the first suction cup assembly 523 driving the workpiece relative to the workpiece carrier 521 is realized. For example, when the workpiece carrier lifting drive motor 525 drives the workpiece carrier lifting lead screw to rotate forward, the length of the robotic arm 522 extending relative to the workpiece carrier 521 becomes longer, and thus the first suction cup assembly 523 drives the workpiece to rise relative to the workpiece carrier 521; when the workpiece carrier lifting drive motor 525 drives the workpiece carrier lifting lead screw to rotate backward, the length of the robotic arm 522 extending relative to the workpiece carrier 521 is shortened, and thus the first suction cup assembly 523 drives the workpiece to descend relative to the workpiece carrier 521.
[0066] In some embodiments of the present application, to provide sufficient working space for the workpiece carrier device 52, the first cutting station 11, the second cutting station 12, and the first grinding station 15, the second grinding station 16, and the third grinding station 17 have a horizontal overlapping section, and the longitudinal length of the horizontal overlapping section is greater than the longitudinal length of the workpiece carrier device during operation, so that the workpiece carrier device 52 can travel back and forth between the first cutting station 11, the second cutting station 12, and the first grinding station 15, the second grinding station 16, and the third grinding station 17 to perform the transfer operation of the workpiece, thereby promoting the efficient cooperation of the processing of each station.
[0067] To realize the loading and unloading of the workpiece, in one embodiment, a hoisting mechanism may be configured on the gantry. Please refer to Figure 5a and in combination with Figure 2 , where Figure 5a shows a schematic diagram of the hoisting mechanism installed on the gantry in one embodiment of the present application. As Figure 2 shown, the workpiece cutting and grinding integrated equipment of the present application further includes a hoisting mechanism 6. The hoisting mechanism 6 is arranged on the gantry 51 and is used to transfer the workpiece from the stacker to the first loading and unloading station 13 or / and the second loading and unloading station 14 for the loading operation of the workpiece, or to transfer the workpiece that has completed the chamfering operation from the first loading and unloading position 13 or / and the second loading and unloading station 14 to the stacker for the unloading operation of the workpiece.
[0068] Please refer to Figure 5b which shows a schematic structural diagram of the hoisting mechanism in the embodiment of the present application Figure 5a as shown. As Figure 5b shown, the hoisting mechanism 6 includes a hoisting arm 61, a hoisting assembly 62, and a second suction cup assembly 63.
[0069] The hoisting arm 61 is used to realize the lateral movement of the hoisting mechanism 6 on the gantry 51, and thus realize the switching of the hoisting mechanism 6 between the first loading and unloading station 13 and the second loading and unloading station 14. For this purpose, a laterally extending lateral hoisting guide rail is provided on the gantry 51. Correspondingly, a lateral hoisting slider is provided on the hoisting arm 61 and corresponds to the lateral hoisting guide rail. In some embodiments, the hoisting mechanism 6 further includes a lateral hoisting drive unit, which may include: a lateral hoisting rack, a lateral hoisting gear, and a lateral hoisting drive motor. The lateral hoisting rack is laterally disposed on the gantry 51, the lateral hoisting gear is disposed on the hoisting arm 61 and meshes with the lateral hoisting rack, and the lateral hoisting drive motor is used to drive the lateral hoisting gear to rotate so that the associated hoisting arm 61 moves along the lateral hoisting rack, thereby realizing the lateral movement of the hoisting mechanism 6. For example, when the lateral hoisting drive motor drives the lateral hoisting gear to rotate forward, the hoisting mechanism 6 is driven to move leftward laterally along the lateral hoisting rack; when the lateral hoisting drive motor drives the lateral hoisting gear to rotate reversely, the hoisting mechanism 6 is driven to move rightward laterally along the lateral hoisting rack.
[0070] In some embodiments, the lateral hoisting drive unit may include a lateral hoisting lead screw and a lateral hoisting drive motor. The lateral hoisting lead screw is laterally disposed and associated with the hoisting arm 61, and the lateral hoisting drive motor is associated with the lateral hoisting lead screw. By using the lateral hoisting drive motor to drive the lateral hoisting lead screw to rotate forward and backward, the hoisting arm 61 is driven to move left and right laterally along the lateral hoisting guide rail, thereby realizing the lateral movement of the hoisting mechanism 6. For example, when the lateral hoisting drive motor drives the lateral hoisting lead screw to rotate forward, the hoisting mechanism 6 is driven to move leftward laterally along the lateral hoisting guide rail; when the lateral hoisting drive motor drives the lateral hoisting lead screw to rotate reversely, the hoisting mechanism 6 is driven to move rightward laterally along the lateral hoisting guide rail.
[0071] As shown in the example of Figure 5b the second suction cup assembly 63 has the same configuration as the first suction cup assembly 523, and its structure and function will not be elaborated here. This is hereby stated.
[0072] In one embodiment, one end of the lifting assembly 62 is connected to the lifting arm 61, and the other end is connected to the second suction cup assembly 63. In order to achieve the lifting movement of the second suction cup assembly, and further achieve the extraction or placement of the workpiece at the first loading and unloading station or the second loading and unloading station, the lifting assembly 62 includes a lifting mechanism. In one implementation, the lifting mechanism may include a steel wire rope, a hook, and a lifting driving source. Among them, the steel wire rope connects the lifting arm 61 and the lifting assembly 62 through the hook. The lifting driving source may be a motor, for example, and the motor is associated with the steel wire rope. The motor can be used to drive the steel wire rope to lengthen or shorten, so as to achieve the lifting movement of the workpiece relative to the first loading and unloading station or the second loading and unloading station.
[0073] When using Figure 5b the shown lifting mechanism for loading, the lifting mechanism 6 moves to the position of the first-specification workpiece on the stacker under the action of the horizontal lifting driving unit and the lifting mechanism, and then uses the second suction cup assembly 63 to transfer the two first-specification workpieces to the first loading and unloading station 13 or / and the second loading and unloading station 14 in batches for subsequent cutting operations. It should be noted that the two first-specification workpieces may be both placed on the first loading and unloading station, or both placed on the second loading and unloading station 14, or respectively placed on the first loading and unloading station 13 and the second loading and unloading station 14. The present application does not make any restrictions on this.
[0074] For the convenience of distinction, the two first-specification workpieces to be cut are called the first workpiece and the second workpiece. When using Figure 4a the shown workpiece transfer mechanism to transfer the first workpiece and the second workpiece at the loading and unloading positions (i.e., the first loading and unloading station 13 and the second loading and unloading station 14), the workpiece transfer translation driving unit drives the workpiece transfer device 52 to move horizontally on the gantry 51 along the horizontal guide rail 511 to the position of the first workpiece until the suction cup body touches the top surface of the first workpiece, and adsorbs the first workpiece under the drive of the air source; then, the workpiece transfer lifting mechanism drives the robotic arm 522 to rise vertically relative to the workpiece transfer seat 521, the workpiece transfer device 52 moves horizontally on the gantry 51 along the horizontal guide rail 511 to the first cutting station 11, the workpiece transfer lifting mechanism drives the robotic arm 522 to descend vertically relative to the workpiece transfer seat 521, and the air source drives the suction cup body to release the first workpiece; then, the workpiece transfer device 52 transfers the second workpiece to the second cutting station 12 under the action of the workpiece transfer translation driving unit and the workpiece transfer lifting mechanism. The cooperation working process of the workpiece transfer device 52 and the gantry 51 can be referred to the previous description and will not be elaborated here.
[0075] In addition, the first workpiece and the second workpiece can be transported to the first cutting station 11 for cutting operations or to the second cutting station 12 for cutting operations, and the present application does not impose any restrictions on this. In the above embodiments, through the first cutting station 11 and the second cutting station 12 in the present application and the configuration of the workpiece transporting device 52 relative to the two, the cooperation between the first cutting station 11, the second cutting station 12 and the workpiece transporting mechanism 5 is flexible, and the specific operation process can be adjusted at any time according to production requirements.
[0076] Please refer to Figures 6 to 7b , wherein, Figure 6 which shows a schematic structural view of the cutting area of the workpiece cutting and grinding integrated device of the present application in an embodiment. Figure 7a which shows a schematic structural view of the second cutting device in the workpiece cutting and grinding integrated device of the present application in an embodiment. Figure 7b which shows a schematic view of the cutting operation of the second cutting device of the present application in an embodiment; as shown in the figure, the second cutting device 22 is disposed on the second cutting station 12 and includes a cutting frame 221, a cutting support 222, and a wire cutting unit.
[0077] The cutting frame 221 serves as a carrier for arranging the wire cutting unit on the second cutting station 12, and its specific form can adopt a beam body, a column body, a plate frame, a bracket, etc.
[0078] The cutting support 222 is movably disposed on the second guide rail 121 on the second cutting station 12 and is used to drive the second cutting device 22 to move longitudinally on the second guide rail 121 to realize cutting of the workpiece. In some embodiments, the cutting support 222 further includes a slider and a cutting drive unit. The slider is disposed at the bottom of the cutting support 222 and is adapted to the corresponding second guide rail 121. The cutting drive unit is used to drive the cutting frame 221 to move longitudinally along the second guide rail 121. In some implementation manners, the cutting drive unit may further include a lead screw and a cutting drive motor, wherein the lead screw is arranged longitudinally and is connected to the cutting support 222, and the cutting drive motor (the cutting drive motor may be, for example, a servo motor) is connected to the lead screw. Thus, the lead screw is driven to rotate by the cutting drive motor, so that the cutting frame 221 can move longitudinally along the second guide rail 121. The implementation manner of the cutting drive unit is not limited thereto, and other components that can realize driving the cutting support to move longitudinally along the second guide rail are still applicable. For example, the cutting drive unit may include a rack, a drive gear meshing with the rack, and a drive motor for driving the drive gear to rotate.
[0079] In another embodiment of the present application, a limit block is further included in the connection assembly between the cutting drive unit and the second guide rail, which is used to limit the excessive displacement of the cutting support during longitudinal movement.
[0080] To achieve the cutting operation, the wire cutting unit is arranged on the cutting frame 221, and the cutting of the workpiece is realized as the cutting frame 221 moves longitudinally from the distal end to the proximal end on the second guide rail 121. The wire cutting unit is arranged on a mounting structure and includes a plurality of cutting wheels, at least one idler wheel, and a cutting loop. The cutting loop is sequentially wound around the cutting wheels and the idler wheel to form a vertical wire saw for cutting the workpiece from a first specification workpiece into two second specification workpieces.
[0081] In the embodiment as Figure 7a and Figure 7b shown, the wire cutting unit includes two cutting wheels 223a, 223b, a tensioning wheel 224a, a driving wheel 224b, and a cutting loop 225. The cutting loop 225 is wound around the two cutting wheels 223a, 223b and the tensioning wheel 224a, driving wheel 224b in a head-to-tail connected annular winding manner to form a vertical wire saw between the two cutting wheels 223a, 223b, and the vertical wire saw is arranged in the transverse direction. The two cutting wheels 223a, 223b and the tensioning wheel 224a, driving wheel 224b and the cutting loop 225 form a quadrilateral, and the quadrilateral can be a rectangle or any quadrilateral.
[0082] The cutting loop 225 can maintain a high-speed rotary motion throughout the cutting process. At the same time, the cutting loop 225 can run in the same running direction during the cutting process. In this way, the second cutting device 22 of the present application can achieve high-precision cutting operations, avoiding problems such as the cutting surface having waviness or uneven flatness caused by the running direction change or running speed of the cutting wire in the existing cutting methods; at the same time, the cutting loop can effectively reduce the total length of the cutting wire required for the wire cutting unit and eliminate components such as the wire take-up reel and wire pay-out reel, reducing production costs and avoiding the problem of uneven tension of the cutting wire. The vertical wire saw formed by the cutting loop can move along the longitudinal direction from the distal end to the proximal end on the second guide rail 121 with the cutting support 222 to realize the cutting of the first specification workpiece on the second cutting carrier at the proximal end of the second guide rail. In a cutting operation of a single transverse movement, the vertical wire saw completely penetrates the first specification workpiece to cut and form two second specification workpieces.
[0083] The second cutting device 22 further includes a cutting wire driving device for driving the cutting loop 225 to run at high speed. In some embodiments, the cutting wire driving device is a servo motor, which has a power output shaft and the power output shaft is shaft-connected to a tensioning wheel or a driving wheel or one of the cutting wheels. In this way, the cutting loop 225 can be driven to run at high speed in the winding direction by the tensioning wheel or the driving wheel or one of the cutting wheels around which it is wound. Of course, the cutting wire driving device can also be other driving sources such as a hydraulic motor, as long as it can drive the cutting loop 225 to run, and this application does not make any restrictions.
[0084] In some implementation manners, the driving wheel 224b is associated with the cutting wire driving device. In some examples, the cutting wire driving device includes a driving motor, and the motor shaft of the driving motor is directly connected to the wheel shaft of the driving wheel 224b. When the driving motor rotates, the driving wheel 224b is driven to rotate by the motor shaft of the driving motor, and the cutting loop 225 is driven to run, causing the two cutting wheels 223a, 223b and the tensioning wheel 224a to rotate, so as to achieve the high-speed running of the cutting loop 225. In some examples, the cutting wire driving device includes a driving motor and a transmission belt. The transmission belt is sleeved on the motor shaft of the driving motor and the wheel shaft of the driving wheel 224b. When the driving motor rotates, the motor shaft of the driving motor drives the transmission belt to run and then drives the driving wheel 224b to rotate. The cutting loop 225 is driven to run, causing the two cutting wheels 223a, 223b and the tensioning wheel 224a to rotate, achieving the high-speed running of the cutting loop 225.
[0085] In some embodiments, the tensioning wheel 224a further includes a tension adjusting mechanism. During wire cutting operations, the tension of the cutting wire affects the yield and machining accuracy during cutting. The tension adjusting mechanism performs tension detection and adjusts the tension so that the tension of the cutting wire reaches a set threshold value and remains constant during cutting or within a certain range allowed with the constant value as the numerical center. When the tensioning wheel 224a guides and pulls the cutting loop 225, it simultaneously adjusts the tension of the cutting loop 225, which can reduce the probability of the cutting loop breaking and thus reduce the consumption of consumables.
[0086] In some embodiments, the tension adjusting mechanism at least includes: a guide rail, a tension sensor, a servo motor, and a lead screw; the guide rail is disposed on the cutting frame 221 and is used to drive the tension pulley 224a to move. The tension sensor is disposed on the tension pulley 224a, continuously senses the tension value of the cutting loop 225 on the tension pulley 224a, and issues a driving signal when the tension value is less than a preset value; the servo motor is electrically connected to the tension sensor and is used to start working after receiving the driving signal issued by the tension sensor; one end of the lead screw is connected to the tension pulley 224a, and the other end is connected to the servo motor, and when the servo motor works, it pulls the tension pulley 224a to perform a one-way displacement along the guide rail to adjust the tension of the cutting loop 225.
[0087] In some embodiments, the tension adjusting mechanism includes: a link assembly and a tension driving unit, the link assembly is associated with the tension pulley 224a and the tension driving unit, and the link assembly is controlled by the tension driving unit, that is, the link assembly is driven by the tension driving unit to act to drive the tension pulley 224a to generate a position change to adjust the tension of the cutting loop.
[0088] In some implementation manners, the tension driving unit may include a counterweight portion, and the counterweight portion may be associated with the link assembly. When it is necessary to increase the tension of the cutting loop, the counterweight portion is released, the counterweight portion descends, and the link assembly drives the tension pulley 224a to move under the action of the gravity of the counterweight portion, thereby expanding the perimeter of the figure enclosed by the two cutting wheels 223a, 223b and the tension pulley 224a, driving wheel 224b, and increasing the tension of the cutting loop 225. When it is necessary to reduce the tension of the cutting loop, the counterweight portion is lifted, and the link assembly drives the associated tension pulley to move in the reverse direction under the action of the gravity of the counterweight portion, thereby reducing the perimeter of the figure enclosed by the two cutting wheels 223a, 223b and the tension pulley 224a, driving wheel 224b, and reducing the tension of the cutting loop 225. The counterweight portion may include counterweight blocks, wherein the number of the counterweight blocks may vary according to the requirements of the cutting loop tension adjustment. For example, when increasing the tension of the cutting loop, the number of counterweight blocks may be increased, and when reducing the tension of the cutting loop, the number of counterweight blocks may be reduced. In some implementation manners, the tension driving unit may include a pulling cylinder, and the pulling cylinder is associated with the movable tension pulley. The pulling cylinder is used to drive the associated tension pulley to move, and the tension of the cutting loop is adjusted by the change in the position of the tension pulley.
[0089] In some embodiments, the tension adjusting mechanism may include a twisting motor and a twisting shaft. The twisting motor is disposed on the cutting frame, and the twisting shaft is associated with the twisting motor and the tensioning wheel 224a. When increasing the tension of the cutting loop, the twisting motor is driven to rotate in a first direction to drive the tensioning wheel 224a to make a first movement through the twisting shaft, thereby expanding the perimeter of the figure formed by the two cutting wheels 223a, 223b, the tensioning wheel 224a, and the driving wheel 224b, and increasing the tension of the cutting loop 225. When decreasing the tension of the cutting loop, the twisting motor is driven to rotate in a second direction to drive the tensioning wheel 224a to make a second movement through the twisting shaft, thereby reducing the perimeter of the figure formed by the two cutting wheels 223a, 223b, the tensioning wheel 224a, and the driving wheel 224b, and decreasing the tension of the cutting loop 225.
[0090] As shown in Figure 6 the example, the first cutting device 21 and the second cutting device 22 may have the same configuration, and their structures and functions may be referred to the previous description and will not be elaborated here.
[0091] As Figure 7b shown, the vertical wire saw formed by using the second cutting device 22 can vertically cut the first specification workpiece into two second specification workpieces along the dotted line shown in the figure, so as to separate the two second specification workpieces formed by cutting along the cutting surface before the subsequent surface grinding operation to adapt the placement of the two second specification workpieces to the surface grinding operation; in addition, compared with the related art that uses a horizontal wire saw to horizontally cut the first specification workpiece in half, the cutting method provided in the present application makes the two second specification workpieces formed after cutting still located in their original positions, thereby avoiding damage to the second specification workpiece located below caused by the falling of the second specification workpiece located above after horizontal cutting in half.
[0092] As Figure 4a shown, a first guide rail 111 is laid on the first cutting station 11, and a second guide rail 121 is laid on the second cutting station 12. As Figure 6 shown, a first cutting carrier 112 is provided at the proximal end of the first guide rail 111 for carrying the first workpiece; a second cutting carrier 122 is provided at the proximal end of the second guide rail 121 for carrying the second workpiece.
[0093] The following takes the second guide rail and the second cutting carrier as an example for illustration.
[0094] The second guide rail 121 is longitudinally laid on the second cutting station 12, and the second cutting carrier 122 can move transversely relative to the second guide rail 121. Please refer to Figure 8 , which shows a schematic structural diagram of the second cutting carrier in an embodiment of the workpiece cutting and grinding integrated device of the present application. As Figure 8As shown, the second cutting carrier 122 includes a first clamping unit 1221, a second clamping unit 1222, and a transverse guide rail 1223. The transverse guide rail 1223 is disposed at the proximal end of the second guide rail 121 in the transverse direction, and the first clamping unit 1221 and the second clamping unit 1222 are oppositely disposed along the transverse guide rail 1223. Taking the first clamping unit 1221 as an example, the first clamping unit 1221 further includes a first transverse movement base 12211, a first support arm 12212, a first clamping seat 12213, and a first flipping mechanism.
[0095] In one embodiment, the first support arm 12212 is disposed on the first transverse movement base 12211, and the first clamping seat 12213 is pivotally connected to the top end of the first support arm 12212 and is used for clamping a first specification workpiece in a closed state or a second specification workpiece in a separated state. As Figure 8 shown, the first clamping seat 12213 includes a first bearing portion 122131 and a first clamping portion 122132. The first bearing portion 122131 includes a bottom bearing surface and a lateral bearing surface. When supporting a workpiece, the bottom bearing surface contacts the bottom surface of the workpiece, and the lateral bearing surface contacts a side surface of the workpiece.
[0096] In one embodiment, the first support arm 12212 has a laterally extending support portion for supporting the bottom surface of the first bearing portion 122131. In one implementation manner, a buffer member such as a rubber pad is disposed on the support portion, and the buffer member can be attached to the bottom surface of the first bearing portion for buffering when carrying a workpiece. The support manner of the support portion includes but is not limited to point support.
[0097] Please refer to Figure 9, which shows a schematic structural diagram of the second cutting carrier of the present application in an embodiment. As shown in the figure, in order to more stably support the workpiece, the first clamping portion 122132 is disposed on the top of the lateral bearing surface of the first bearing portion 122121 for clamping the workpiece in the height direction of the workpiece. In some embodiments, an elastic element such as a rubber pad is further added to the first clamping portion, and the elastic element can be in contact with the top surface of the workpiece, playing a buffering role for the workpiece while pressing the workpiece to prevent damage to the workpiece. In some embodiments, the first clamping portion includes two clamping members and a clamping driving unit. The clamping members are used to descend to press the top surface of the workpiece, and the clamping driving unit is associated with the clamping members for driving the clamping members to descend to press the top surface of the workpiece. In some embodiments, the clamping driving unit may include a driving cylinder or a driving hydraulic cylinder with a telescopic rod. Taking the driving cylinder as an example, the driving cylinder is fixedly arranged, and the telescopic rod is associated with the clamping member. Thus, the driving cylinder can be used to drive the clamping member to descend, thereby realizing the pressing of the top surface of the workpiece. In some embodiments, the clamping driving unit may include a lead screw and a driving motor, wherein the lead screw is associated with the clamping member, and the driving motor is used to drive the lead screw to rotate forward and backward to drive the clamping member to move vertically.
[0098] In order to realize the clamping or release of the workpiece located on the first clamping seat, the first clamping portion 122132 further includes a rotating mechanism, and the rotating mechanism is associated with the first clamping portion and drives the clamping member to rotate a certain angle to clamp or release the workpiece. In some embodiments, the rotating mechanism includes a rotation driving source, and under the drive of the rotation driving source, the clamping member of the first clamping portion can be driven to rotate along its axis. The rotation driving source can be, for example, a rotating motor, but is not limited thereto.
[0099] To achieve the lateral movement of the second cutting carrier 122 relative to the second guide rail 121, and thus the lateral movement of the first clamping unit 1221 and the second clamping unit 1222, the first transverse moving seat 12211 is arranged on the lateral guide rail 1223. Correspondingly, a lateral translation slider is arranged on the first transverse moving seat 12211, and the lateral translation slider corresponds to the lateral guide rail 1223. In some embodiments, the second cutting carrier 122 further includes a lateral translation driving unit, and the lateral translation driving unit may include: a lateral translation rack, a lateral translation gear, and a lateral translation driving motor. The lateral translation rack is arranged horizontally on the lateral guide rail, the lateral translation gear is arranged on the first transverse moving seat and meshes with the lateral translation rack, and the lateral translation driving motor is used to drive the lateral translation gear to rotate so that the associated first transverse moving seat moves along the lateral translation rack, thereby achieving the lateral movement of the first clamping unit. For example, when the lateral translation driving motor drives the lateral translation gear to rotate forward, it drives the first clamping unit to move horizontally to the left along the lateral translation rack; when the lateral translation driving motor drives the lateral translation gear to rotate in reverse, it drives the clamping unit to move horizontally to the right along the lateral translation rack.
[0100] In some embodiments, the lateral translation driving unit may include a lateral translation lead screw and a lateral translation driving motor. The lateral translation lead screw is arranged horizontally and is associated with the first transverse moving seat, and the lateral translation driving motor is associated with the lateral translation lead screw. By using the lateral translation driving motor to drive the lateral translation lead screw to rotate forward and backward, the first transverse moving seat is driven to move horizontally left and right along the lateral translation guide rail, thereby achieving the lateral movement of the first clamping unit. For example, when the lateral translation driving motor drives the lateral translation lead screw to rotate forward, it drives the clamping unit to move horizontally to the left along the lateral translation guide rail; when the lateral translation driving motor drives the lateral translation lead screw to rotate in reverse, it drives the clamping unit to move horizontally to the right along the lateral translation guide rail.
[0101] The second clamping unit includes a second transverse moving seat. In one embodiment, the second transverse moving seat and the first transverse moving seat may share the same lateral translation driving unit. In one implementation, the lateral translation lead screw may be designed as a bidirectional lead screw, which may also be called a left - right hand lead screw, also known as a positive - negative thread lead screw. One end of it has a left - hand thread, and the other end has a right - hand thread. Thus, by using the lateral translation driving motor to drive the bidirectional lead screw to rotate forward and backward, the first clamping unit and the second clamping unit are driven to move towards each other in the lateral direction to be in a closed state or move away from each other to be in a separated state. As Figure 9 shown, the first clamping unit and the second clamping unit are used to carry the first - specification workpieces in the closed state. Please refer to Figure 10, showing a schematic structural diagram of the second cutting carrier of the present application in another embodiment, as Figure 10 shown, the first clamping unit and the second clamping unit are used to respectively carry two second-standard workpieces formed by half-cutting in the separated state. In addition, when the first clamping unit and the second clamping unit are in a separated state in the lateral direction, a wire-retreating space can be left for the cutting device that has completed the cutting operation.
[0102] After the second cutting device completes the cutting operation of the second workpiece on the second cutting carrier from the first-standard workpiece to the second-standard workpiece, the two formed second-standard workpieces are respectively supported by the first clamping unit and the second clamping unit. The first clamping unit and the second clamping unit move away from each other under the drive of the lateral translation drive unit to be in a separated state, thereby driving the two second-standard workpieces to move away from each other, leaving a wire-retreating space for the second cutting device; after the wire retreat is completed, the first clamping unit and the second clamping unit drive the cutting surfaces of the carried second-standard workpieces to be switched from the vertical direction to the horizontal direction under the drive of the first flipping mechanism.
[0103] Please refer to Figure 11 , showing a schematic structural diagram of the second cutting carrier of the present application in yet another embodiment. In one embodiment, the first flipping mechanism is arranged on the first transverse moving seat 12211 and includes a telescopic rod and a driving cylinder. The telescopic rod is pivotally connected to the first clamping seat 12213, and when telescoping, drives the side surface of the first clamping seat 12213 to be switched from the vertical direction to the horizontal direction so that the cutting surface of the second-standard workpiece is switched from the vertical direction to the horizontal direction. The driving cylinder is fixedly arranged on the first clamping seat 12213 and is used to drive the telescopic rod to perform telescopic movement so that the telescopic rod drives the first clamping seat to actuate. Thus, when the driving cylinder drives the telescopic rod to perform a contraction movement, the side surface of the first clamping seat is pulled by the contracting telescopic rod to be switched from the vertical direction to the horizontal direction so that the cutting surface of the second-standard workpiece is switched from the vertical direction to the horizontal direction; when the driving cylinder drives the telescopic rod to perform an extending movement, the side surface of the first clamping seat is pulled by the extending telescopic rod to be switched from the horizontal direction to the vertical direction.
[0104] As shown in Figure 6 the example, the first cutting carrier 112 and the second cutting carrier 122 can have the same configuration, and their structures and functions can be referred to the previous description and will not be elaborated here.
[0105] As shown in Figure 8 the example, the second clamping unit 1222 includes a second transverse moving seat, a second support arm, a second clamping seat, and a second flipping mechanism, which has the same configuration as the first clamping unit, and their structures and functions can be referred to the previous description and will not be elaborated here.
[0106] As described above, the transfer device 52, in cooperation with the gantry 51, places the first workpiece or the second workpiece at the cutting position. Still taking the second cutting device 22 and the second cutting carrier 122 as an example, in one embodiment, the workpiece transfer mechanism 5 transfers the second workpiece to the second cutting carrier 122 located at the proximal end of the second guide rail 121. The first clamping unit 1221 and the second clamping unit 1222 move horizontally relative to each other along the transverse guide rail 1223 under the drive of the lateral translation drive unit to the closed state, so that the second workpiece is clamped by the first clamping unit 1221 and the second clamping unit 1222. At this time, the first clamping portion 122132 and the clamping portion of the second clamping unit rotate to directly above the second workpiece under the drive of the rotating mechanism, and descend and press against and fix the second workpiece under the drive of the clamping drive unit.
[0107] Subsequently, the cutting loop 225 of the second cutting device 22 located at the distal end of the second guide rail 121 runs at high speed under the drive of the cutting line drive device. The formed vertical wire saw moves along the longitudinal direction from the distal end to the proximal end on the second guide rail 121 with the cutting support 222 until the vertical wire saw completely penetrates the second workpiece on the second cutting carrier 122 located at the proximal end of the second guide rail 121, forming Figure 10 the workpiece A and the workpiece B as shown. Then, the first clamping unit 1221 and the second clamping unit 1222 move horizontally away from each other along the transverse guide rail 1223 under the drive of the lateral translation drive unit to the separated state, so that the first clamping unit 1221 carries the workpiece A, and the second clamping unit 1222 carries the workpiece B and is separated laterally relative to each other to leave a wire withdrawal space. At this time, the vertical wire saw moves along the longitudinal direction from the proximal end to the distal end on the second guide rail 121 with the cutting support 222 to complete the withdrawal of the cutting line.
[0108] Next, the first clamping unit 1221 and the second clamping unit 1222 drive the cutting surfaces of the carried workpiece A and workpiece B to be switched from vertical to horizontal under the drive of their respective flipping mechanisms, forming Figure 11 the state as shown; the first clamping portion 122132 and the clamping portion of the second clamping unit release the workpiece A and the workpiece B under the drive of their respective rotating mechanisms and clamping drive units; the transfer device 52, in cooperation with the gantry 51, transfers the workpiece A and the workpiece B to the grinding position for subsequent grinding operations. Finally, the first clamping unit 1221 and the second clamping unit 1222 are flipped again under the drive of their respective flipping mechanisms to the state as shown in Figure 8 to wait for the cutting operation of the next workpiece.
[0109] Please refer to Figure 12, which shows a schematic structural diagram of the grinding area of the workpiece cutting and grinding integrated equipment of the present application in an embodiment. As shown in the figure, a third guide rail 151 is laid on the first grinding station 15, and a fourth guide rail 161 is laid on the second grinding station 16. A first grinding carrier 152 is arranged on the third guide rail 151, and a second grinding carrier 162 is arranged on the fourth guide rail 161. The first grinding carrier 152 and the second grinding carrier 162 are used to clamp the second specification workpiece in the width direction of the workpiece, and drive the workpiece to move longitudinally when driven to complete the grinding operation of the second specification workpiece.
[0110] The following takes the first grinding carrier as an example for illustration.
[0111] Please refer to Figure 13 and combine with Figure 12 , wherein, Figure 13 which shows a schematic structural diagram of the first grinding carrier of the present application in an embodiment. As Figure 13 shown, the first grinding carrier 152 includes a first bearing unit 1521, a second bearing unit 1522, and a bearing seat 1523. The first bearing unit 1521 and the second bearing unit 1522 are jointly arranged on the bearing seat 1523, and are respectively used to bear two second specification workpieces formed by cutting.
[0112] In an embodiment, the bearing seat 1523 is longitudinally movably arranged on the third guide rail 151, and is used to drive the first grinding carrier 152 to move longitudinally on the third guide rail 151 to realize the grinding operation of the workpiece. In some embodiments, the bearing seat 1523 further includes a slider and a bearing driving unit. The slider is arranged at the bottom of the bearing seat 1523 and is adapted to the corresponding third guide rail 151. The bearing driving unit is used to drive the bearing seat 1523 to move longitudinally along the third guide rail 151. In some implementation manners, the bearing driving unit may further include a lead screw and a bearing driving motor. Among them, the lead screw is arranged longitudinally and is connected to the bearing seat 1523, and the bearing driving motor (the bearing driving motor may be, for example, a servo motor) is connected to the lead screw. In this way, the bearing driving motor drives the lead screw to rotate, so as to realize the longitudinal movement of the bearing seat 1523 along the third guide rail 151. The implementation manner of the bearing driving unit is not limited thereto, and other components that can realize driving the bearing seat to move longitudinally along the third guide rail and then drive the first bearing unit 1521 and the second bearing unit 1522 to move longitudinally are still applicable. For example, the bearing driving unit may include a rack, a driving gear meshing with the rack, and a driving motor for driving the driving gear to rotate.
[0113] In another embodiment of the present application, a limiting block is further included in the connection assembly between the bearing driving unit and the third guide rail, which is used to limit the excessive displacement of the bearing seat during longitudinal movement.
[0114] Taking the first bearing unit as an example, as Figure 13 shown, the first bearing unit 1521 includes a backrest 15211, a lateral pressing assembly 15212, and a bottom support surface 15213. The backrest 15211 and the lateral pressing assembly 15212 are respectively located on opposite sides of the bottom support surface 15213.
[0115] The backrest 15211 is fixedly arranged along the longitudinal direction on one side of the bottom support surface 15213. In some embodiments, an elastic element such as a rubber pad is further provided on the contact surface between the backrest and the workpiece. The elastic element can be attached to the side surface of the second specification workpiece, playing a buffering role for the second specification workpiece while pressing it, and preventing damage to the second specification workpiece. In some other embodiments, the backrest 15211 of the first bearing unit 1521 and the backrest of the second bearing unit 1522 are arranged back to back and at intervals. The lateral pressing assembly 15212 is longitudinally movably arranged on the other side of the bottom support surface 15213 of the bearing seat, and is used to laterally open to release the carried second specification workpiece and laterally press to fix the second specification workpiece on the bottom support surface of the bearing seat 1523.
[0116] In one embodiment, the lateral pressing assembly 15212 includes a pressing rod and a pressing driving unit.
[0117] The pressing rod further includes a pressing part, a connecting part, and a shaft connecting part. The pressing part is used to press against the side vertical surface of the second specification workpiece. In some embodiments, an elastic element such as a rubber pad is further provided on the pressing part. The elastic element can be attached to the side vertical surface of the second specification workpiece, playing a buffering role for the second specification workpiece while pressing it, and preventing damage to the second specification workpiece.
[0118] The connecting part is used to connect the pressing driving unit. The shaft connecting part is located between the pressing part and the connecting part and is shaft-connected to the bearing seat. The ways for the pressing rod to be shaft-connected to the bearing seat include but are not limited to a core shaft, a flexible shaft, a solid shaft, and a hollow shaft, and the materials thereof include but are not limited to cast iron and carbon structural steel.
[0119] The pressing driving unit is arranged on the lower side of the bottom supporting surface and is used to drive the pressing rod. In some embodiments, the pressing driving unit may include a driving cylinder or a driving hydraulic cylinder with a telescopic rod. Taking the driving cylinder as an example, the driving cylinder is fixedly arranged, and the telescopic rod is associated with the pressing rod of the lateral pressing assembly. In this way, the driving cylinder can be used to drive the pressing rod to move laterally, so as to realize lateral opening to release the carried second-specification workpiece and lateral pressing to fix the second-specification workpiece on the carrying seat.
[0120] In some embodiments, the pressing driving unit may include a lead screw and a driving motor. Among them, the lead screw is associated with the pressing rod of the lateral pressing assembly, and the driving motor is used to drive the lead screw to rotate forward and backward to drive the pressing rod to move laterally. In some embodiments, the backstop can also be set as a movable lateral pressing assembly. At this time, when both ends of the bottom supporting surface of the carrying seat for fixing the second-specification workpiece are movable, the lead screw can be designed as a bidirectional lead screw. The bidirectional lead screw can be called a left-right hand lead screw, also known as a positive-negative thread lead screw. One end of it is a left-handed thread, and the other end is a right-handed thread. In this way, the driving motor is used to drive the bidirectional lead screw to rotate forward and backward to drive the backstop and the lateral pressing assembly to move towards or away from each other laterally, so as to realize lateral opening to release the carried second-specification workpiece and lateral pressing to fix the second-specification workpiece on the carrying seat.
[0121] In an embodiment of the present application, the number of the lateral pressing assemblies is at least two groups, and they are evenly spaced along the longitudinal direction of the carrying seat. For example, in some embodiments, the number of the lateral pressing assemblies can be, for example, two groups. The two groups of lateral pressing assemblies are longitudinally arranged on the carrying seat, and under the drive of the pressing driving unit, they are laterally opened to release the carried second-specification workpiece and laterally pressed to fix the second-specification workpiece on the bottom supporting surface of the carrying seat.
[0122] The number of the lateral pressing assemblies can be, for example, three groups. The three groups of lateral pressing assemblies are longitudinally arranged on the carrying seat, evenly spaced along the longitudinal direction of the carrying seat, and under the drive of the pressing driving unit, they are laterally opened to release the carried second-specification workpiece and laterally pressed to fix the second-specification workpiece on the bottom supporting surface of the carrying seat. However, it is not limited thereto, as long as the second-specification workpiece can be stably fixed on the carrying seat.
[0123] In order not to affect the grinding operation during the operation of the grinding device, in one embodiment, the height of the backstop and the lateral pressing assembly is less than the height of the second-specification workpiece placed on the carrying seat. It should be understood that the setting and lateral opening of the backstop and the lateral pressing assembly should not come into contact and collision with the grinding device, and there should be independent operating spaces for each other to avoid damage to the equipment.
[0124] Present as Figure 12 As shown in the example, the first bearing unit 1521 and the second bearing unit 1522 are symmetrically arranged on the bearing seat, and the first grinding carrier 152 and the second grinding carrier 162 can be configured in the same manner. Therefore, the structure and function of the second bearing unit 1522 and the second grinding carrier 162 can refer to the previous description and will not be repeated here.
[0125] In order to cooperate with the first grinding carrier and the second grinding carrier to perform grinding operations, the first and second planar spindles in the first grinding device are arranged on the side of the spindle frame facing the distal end, and are used to perform grinding operations on the top surface of the workpiece moving on the first grinding station; the third and fourth planar spindles in the second grinding device are arranged on the side of the spindle frame facing the distal end, and are used to perform grinding operations on the top surface of the workpiece moving on the second grinding station.
[0126] Specifically, please combine Figure 3 and Figure 12 As shown in the figure, the first plane spindle 41, the second plane spindle 42, the third plane spindle 43, and the fourth plane spindle 44 are all arranged on the side of the spindle frame 3 facing the distal end. Taking the first plane spindle and the second plane spindle as an example, when the first surface grinding device is used to perform the first surface grinding operation on the two second-specification workpieces formed by half cutting, the first bearing unit 1521 and the second bearing unit 1522 of the first grinding carrier located at the proximal end of the first grinding station 15 respectively carry the two second-specification workpieces, and fix the side elevations of the two second-specification workpieces under the action of the backrest and lateral clamping components; then, the first grinding carrier 152 carries and drives the two second-specification workpieces to move from the proximal end to the distal end, and performs the first surface grinding operation on the two second-specification workpieces under the simultaneous actuation of the first plane spindle 41 and the second plane spindle 42.
[0127] In one embodiment of the present application, the end faces of the first plane spindle 41 and the second plane spindle 42 of the first grinding device are both provided with a fine grinding wheel and a retractable rough grinding wheel sleeved in the fine grinding wheel. The rough grinding wheel is concentrically arranged on the end face of the spindle with the fine grinding wheel and suspended on the upper side of the first grinding station 15. Such an arrangement makes the structure of the first grinding device more compact.
[0128] Taking the first planar main shaft as an example, in some implementations, the first planar main shaft further includes a first transmission shaft (bushing) in a cylindrical structure and a second transmission shaft accommodated in the cylindrical structure. Among them, the bushing is connected to the fine grinding wheel so as to drive the fine grinding wheel to rotate when the bushing rotates, and the second transmission shaft is connected to the rough grinding wheel so as to drive the rough grinding wheel to rotate when the second transmission shaft rotates. The second planar main shaft has the same configuration as the first planar main shaft. Based on the first planar main shaft and the second planar main shaft, the principle of the first grinding device to perform its grinding operation is as follows: when it is necessary to perform rough grinding on two workpieces of the second specification, the second transmission shaft is moved along its axial direction so that the rough grinding wheel protrudes / extends relative to the fine grinding wheel, and combined with the movement of the first grinding device along the vertical guide rail on the main shaft frame, the rough grinding wheel can reach the grinding position, and then the rough grinding wheel is driven to rotate by rotating the second transmission shaft. When it is necessary to perform fine grinding on two workpieces of the second specification, the telescopic movement of the second transmission shaft is used to make the rough grinding wheel in a position where it does not interfere with the fine grinding wheel. Based on this, combined with the movement of the first grinding device along the vertical guide rail on the main shaft frame, the fine grinding wheel can reach the grinding position, and then the fine grinding wheel is driven to rotate by rotating the first transmission shaft.
[0129] In another embodiment, the rough grinding wheel and the fine grinding wheel are concentrically arranged, and the fine grinding wheel is nested inside the rough grinding wheel. In some implementations, the first planar main shaft further includes a first transmission shaft (bushing) in a cylindrical structure and a second transmission shaft accommodated in the cylindrical structure. Among them, the bushing is connected to the rough grinding wheel so as to drive the rough grinding wheel to rotate when the bushing rotates, and the second transmission shaft is connected to the fine grinding wheel so as to drive the fine grinding wheel to rotate when the second transmission shaft rotates. The second planar main shaft has the same configuration as the first planar main shaft. Based on the first planar main shaft and the second planar main shaft, the principle of the first grinding device to perform its grinding operation is as follows: when it is necessary to perform fine grinding on two workpieces of the second specification, the second transmission shaft is moved along its axial direction so that the fine grinding wheel protrudes relative to the rough grinding wheel, and combined with the movement of the first grinding device along the vertical guide rail on the main shaft frame, the fine grinding wheel can reach the grinding position, and then the fine grinding wheel is driven to rotate by rotating the second transmission shaft. When it is necessary to perform rough grinding on two workpieces of the second specification, the telescopic movement of the second transmission shaft is used to make the fine grinding wheel in a position where it does not interfere with the rough grinding wheel. Based on this, combined with the movement of the first grinding device along the vertical guide rail on the main shaft frame, the rough grinding wheel can reach the grinding position, and then the rough grinding wheel is driven to rotate by rotating the first transmission shaft.
[0130] In some embodiments of the present application, the rough grinding wheel is circular and has a through hole in the middle. The rough grinding wheel is formed by consolidating abrasive grains and a binder, and a surface with an abrasive grain portion contacts and rotates with the surfaces of two workpieces of the second specification to be ground. The rough grinding wheel has a certain abrasive grain size and abrasive grain density, and at the same time, there are pores in the rough grinding wheel. The abrasive of the rough grinding wheel can be set as alumina, silicon carbide, diamond, cubic boron nitride, etc., which are abrasive grains with a hardness greater than the hardness of the material of the workpiece of the second specification according to the needs of grinding the workpiece of the second specification. The abrasive grain size of the fine grinding wheel is smaller than that of the rough grinding wheel, and the other general configurations of the grinding wheel are basically the same as those of the rough grinding wheel.
[0131] In some other embodiments, the first grinding surface device further includes a cooling device to cool the rough grinding wheel and the fine grinding wheel, reduce the damage to the surface layers of the two workpieces of the second specification during the grinding process, and improve the grinding efficiency and service life of the grinding wheel. In one implementation, the cooling device includes a cooling water pipe, a diversion groove, and a diversion hole.
[0132] In another implementation, a protective cover for placing a rotary drive motor for cooling water to enter the grinding wheel is provided on the outer edge of the circumference of the grinding wheel. One end of the cooling water pipe is connected to a cooling water source, and the other end is connected to the surface of the protective cover of the grinding wheel. The diversion groove is provided on the protective cover as the contact point between the protective cover and the cooling water pipe, and the diversion hole is provided in the cooling groove. The coolant of the cooling device can be common cooling water. The cooling water pipe is connected to the cooling water source, and the cooling water sucked through the cooling water pipe reaches the diversion groove and the diversion hole on the surface of the grinding wheel, and is guided directly to the contact surface between the grinding wheel and the two workpieces of the second specification to be ground for cooling. During the grinding of the grinding wheel, the cooling water in the diversion hole enters the inside of the grinding wheel by centrifugal force for sufficient cooling.
[0133] The second, third, and fourth plane spindles have the same configuration as the first plane spindle, and their structures and functions can be referred to the previous description and will not be elaborated here.
[0134] In an embodiment, a detection device is provided at the distal end of the first, second, third, or fourth plane spindle. The detection device is used to detect the flatness of the top surface of the workpiece of the second specification during the grinding operation in real time. In one implementation, the detection device is associated with the grinding surface device, calculates the remaining number of processing times according to the flatness of the top surface of the workpiece of the second specification. When the remaining number of processing times is zero, the monitoring device controls the corresponding plane spindle of the grinding surface device to stop operating and rises along the vertical guide rail on the spindle frame to move away from the workpiece of the second specification, thereby ending the grinding operation.
[0135] Please combine Figures 12 to 13, taking the surface grinding operation at the first grinding station 15 as an example, the workpiece transporting device 52 cooperates with the gantry 51 to sequentially transport the cut workpieces A and B, and thus place the workpieces A and B on the first bearing unit 1521 and the second bearing unit 1522 at the proximal end of the third guide rail 151 respectively. At this time, the lateral pressing components of the first bearing unit 1521 and the second bearing unit 1522 respectively cooperate with the common backstop under the drive of their respective pressing drive units to fix the workpieces A and B on the first grinding carrier 152. The first grinding carrier 152 longitudinally moves along the third guide rail 151 from the proximal end to the distal end under the drive of the bearing drive unit.
[0136] Subsequently, the first surface spindle 41 and the second surface spindle 42 descend along the vertical guide rail provided on the spindle frame 3 into the grinding position. The rough grinding wheels in the first surface spindle 41 and the second surface spindle 42 rotate at high speed around the transmission shaft and extend to contact the distal ends of the workpieces A and B. When the workpieces A and B pass by the rough grinding wheels once on the first grinding carrier 152 from the proximal end to the distal end of the third guide rail 151, the first surface grinding device completes one rough grinding from the distal end to the proximal end of the workpieces A and B; at this time, the workpieces A and B move from the distal end to the proximal end of the third guide rail 151 driven by the first grinding carrier 152, and the rough grinding wheels retract to the initial position along the transmission shaft so that the fine grinding wheels extend / protrude relative to the rough grinding wheels, and the rough grinding wheels are in a position where they do not interfere with the fine grinding wheels. The first surface spindle 41 and the second surface spindle 42 drive the fine grinding wheels to descend along the vertical guide rail provided on the spindle frame 3 and contact the proximal ends of the workpieces A and B. When the workpieces A and B pass by the fine grinding wheels once on the first grinding carrier 152 from the distal end to the proximal end of the third guide rail 151, the first surface grinding device completes one fine grinding from the proximal end to the distal end of the workpieces A and B.
[0137] In some other embodiments, the workpiece needs to move from the proximal end to the distal end and then from the distal end to the proximal end two or more times at the first station to complete the rough grinding of cutting. It should be understood that in some embodiments, the workpiece needs to longitudinally move two or more times at the first station to complete the fine grinding of one top surface. The specific number of movements depends on the detection results of the detection device, and the present application does not limit this.
[0138] After the surface grinding operation is performed on the two second-specification workpieces formed by cutting, the two second-specification workpieces are transported to the chamfering area in batches by the workpiece transporting mechanism for subsequent chamfering operations. Please refer to Figure 14, which shows the structural schematic diagram of the chamfering area of the workpiece cutting and grinding integrated equipment of the present application in an embodiment. As shown in the figure, a fifth guide rail 171 is laid on the third grinding station 17, and a third grinding carrier 172 is arranged on the fifth guide rail 171. The third grinding carrier 172 is used to clamp the second-specification workpiece that has completed the grinding operation in the width direction of the workpiece, and drive the second-specification workpiece to move longitudinally when driven to complete the chamfering operation of the second-specification workpiece.
[0139] As shown in Figure 14 the example, the configuration of the third grinding carrier is the same as that of the first grinding carrier and the second grinding carrier. For its structure and function, reference can be made to the previous description and will not be elaborated here.
[0140] In order to cooperate with the third grinding carrier to perform the chamfering operation, as Figure 14 shown, the third grinding station 17 includes a transverse movement component, which is arranged on one side of the main spindle frame 3 adjacent to the second cutting station, and includes a transverse bracket 173, a transverse support plate 174, and a flipping unit. The edge spindle 45 is arranged on the transverse movement component and is used to chamfer the top edges of two second-specification workpieces moving on the third grinding station 13.
[0141] In order to realize the lowering or rising of the edge spindle, and thus realize the start or end of the chamfering operation, the transverse bracket 173 is movably arranged in a lifting manner on one side of the main spindle frame 3 adjacent to the second cutting station. In an embodiment, the transverse bracket includes a lifting mechanism, and the lifting mechanism includes a lifting guide rail, a lifting slider, and a lifting driving unit. The lifting guide rail and the lifting driving unit are arranged on the main spindle frame, the lifting slider is arranged on the transverse bracket, and the lifting driving unit is used to drive the transverse bracket to move up and down along the lifting guide rail, so as to drive the edge spindle 45 to move up and down along the lifting guide rail. In practical applications, in order to make the edge spindle realize stable lifting, a double-guide rail design can be adopted, that is, two lifting guide rails are adopted, and these two lifting guide rails can be arranged in parallel.
[0142] In addition, the lifting driving unit may further include a lifting lead screw and a lifting motor. Among them, the lifting lead screw is arranged vertically and connected to the transverse bracket, and the lifting motor (the lifting motor can be, for example, a servo motor) is connected to the lifting lead screw. In this way, the lifting motor drives the lifting lead screw to rotate, so as to realize the up and down movement of the transverse bracket along the lifting guide rail. The implementation manner of the lifting driving unit is not limited to this, and other components that can realize driving the transverse bracket to move up and down along the lifting guide rail are still applicable. For example, the lifting driving unit may include a lifting rack, a driving gear meshing with the lifting rack, and a driving motor for driving the driving gear to rotate.
[0143] In certain other embodiments of the present application, a limit block is further included in the connection assembly between the transverse bracket and the lifting guide rail, which is used to limit the excessive displacement of the edge main shaft during the lifting movement.
[0144] In order to realize the switching of the edge main shaft to the second specification workpiece to be chamfered, the transverse bracket 173 further includes a transverse guide rail 1731. Correspondingly, a transverse slider and a transverse driving unit are provided on the transverse carrier 174. The transverse slider is arranged on the transverse carrier and is adapted to the corresponding transverse guide rail. The transverse driving unit is used to drive the transverse carrier to move transversely along the transverse guide rail, thereby driving the edge main shaft to move transversely along the transverse guide rail. In actual applications, in order to enable the edge main shaft to achieve stable transverse movement, a double-guide rail design can be adopted, that is, two transverse guide rails are used, and these two transverse guide rails can be arranged in parallel.
[0145] In addition, the transverse driving unit may further include a transverse lead screw and a transverse motor. Among them, the transverse lead screw is arranged transversely and is connected to the transverse carrier, and the transverse motor (the transverse motor can be, for example, a servo motor) is connected to the transverse lead screw. In this way, the transverse motor drives the transverse lead screw to rotate, so that the transverse carrier can be realized to move transversely along the transverse guide rail. The implementation manner of the transverse driving unit is not limited thereto, and other components that can realize driving the transverse carrier to drive the edge main shaft to move transversely along the transverse guide rail are still applicable. For example, the transverse driving unit may include a transverse rack, a driving gear meshing with the transverse rack, and a driving motor for driving the driving gear to rotate.
[0146] In certain other embodiments of the present application, a limit block is further included in the connection assembly between the transverse carrier and the transverse guide rail, which is used to limit the excessive displacement of the edge main shaft during the transverse movement.
[0147] In order to realize the switching of the edge main shaft to the top edge of the second specification workpiece during the chamfering operation, the transverse movement assembly includes a flipping unit. The flipping unit is arranged on the transverse carrier and is fixedly connected to the edge main shaft, and is used to drive the edge main shaft to rotate 180° around the vertical axis to a symmetrical position. In one embodiment, the flipping unit includes a flipping driving source, and the flipping driving source is associated with the edge main shaft, so that the edge main shaft rotates 180° around the vertical axis to a symmetrical position to realize the grinding of another top edge of a certain second specification workpiece. In one implementation manner, the flipping driving source can be, for example, a rotating motor.
[0148] It should be understood that the lateral span of the edge main shaft rotating 180° around the vertical axis is equal to or greater than the width of a single workpiece of the second specification. In one embodiment, the lateral span of the edge main shaft rotating 180° around the vertical axis is equal to the width of a single workpiece of the second specification. At this time, the edge main shaft switches from one side edge of a certain second-specification workpiece to the other side edge, and under the drive of the lifting drive unit and the transverse movement drive unit, chamfering operation is performed on the other side edge of the certain second-specification workpiece. In another embodiment, the lateral span of the edge main shaft rotating 180° around the vertical axis is greater than the width of a single workpiece of the second specification. At this time, the edge main shaft switches from one side edge of one second-specification workpiece to the other side edge of another second-specification workpiece, and under the drive of the lifting drive unit and the transverse movement drive unit, chamfering operation is performed on the other side edge of the other second-specification workpiece. In one implementation manner, the chamfering width of the edge main shaft for the top edge of the second-specification workpiece is 0.5 - 1.5 mm. For example, the chamfering width of the top edge of the second-specification workpiece is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm. The chamfering width is determined according to actual processing requirements, and the present application does not make any restrictions on this. The grinding surface of the chamfering of the edge main shaft for the top edge of the second-specification workpiece forms an angle of 45° with the top surface or the side surface of the second-specification workpiece.
[0149] As Figure 12 shown, the axis of the edge main shaft 45 is preset at 45° relative to the vertical to facilitate performing chamfering operation on the top edge of the second-specification workpiece. In the embodiments described in the present application, a fine grinding wheel is provided on the end face of the edge main shaft close to the second-specification workpiece. It can be understood that when chamfering the workpiece, only the edge of the workpiece needs to be finely ground without rough grinding. At this time, the two second-specification workpieces that have completed the grinding surface operation move along the distal end to the proximal end of the fifth guide rail under the support and drive of the third grinding carrier. The fine grinding wheel is in a high-speed running state, and under the drive of the lifting drive unit and the transverse movement drive unit, chamfering operation is performed.
[0150] In another embodiment, a fine grinding wheel and a retractable rough grinding wheel sleeved in the fine grinding wheel are provided on the end face of the edge main shaft close to the second-specification workpiece. The structures and cooperation modes of the fine grinding wheel and the rough grinding wheel are the same as those of the first plane main shaft, and will not be elaborated here.
[0151] As Figure 14As shown, for the convenience of distinction, the two second - specification workpieces that have completed the grinding operation are respectively defined as workpiece C and workpiece D; one side top - edge of workpiece C or workpiece D is defined as the first edge, and the other side top - edge of workpiece C or workpiece D is defined as the second edge. It is not difficult to understand that the first edge of workpiece C and the first edge of workpiece D are on the same side, the second edge of workpiece C and the second edge of workpiece D are on the same side. Of course, the first edge of workpiece C and the second edge of workpiece D are on opposite sides. When chamfering workpieces C and D, in a preferred embodiment, after the edge spindle 45 chamfers the first edge of workpiece C, it is laterally displaced to the first edge of workpiece D to perform chamfering operation under the drive of the lateral drive unit; then, it is flipped 180° under the drive of the flipping unit, and laterally displaced to the second edge of workpiece D to perform chamfering operation under the drive of the lateral drive unit; then it is laterally displaced to the second edge of workpiece C to perform chamfering operation under the drive of the lateral drive unit, thus completing the chamfering operation of workpieces C and D.
[0152] In another alternative embodiment, after the edge spindle 45 chamfers the first edge of workpiece C, it is flipped 180° under the drive of the flipping unit, and laterally displaced to the second edge of workpiece C to perform chamfering operation under the drive of the lateral drive unit; then, it is laterally displaced to the second edge of workpiece D to perform chamfering operation under the drive of the lateral drive unit; then, it is flipped 180° under the drive of the flipping unit, and laterally displaced to the first edge of workpiece D to perform chamfering operation under the drive of the lateral drive unit, thus completing the chamfering operation of workpieces C and D. In the above - mentioned embodiments, based on the configuration of the flipping unit and the lateral drive unit of the present application, the chamfering sequence of the first edge and the second edge of workpieces C and D is flexible, and the specific operation process can be adjusted at any time according to production requirements, and the present application does not limit this.
[0153] Specifically, when chamfering operation is carried out at the chamfering position shown in Figure 14 the workpiece conveying mechanism transfers the two second - specification workpieces that have completed the grinding operation, namely workpiece C and workpiece D, to the third grinding carrier 172 at the proximal end on the fifth guide rail 171 in batches. The third grinding carrier 172 fixes workpieces C and D under the cooperation of the backing and the lateral pressing assembly, and drives workpieces C and D to longitudinally move from the proximal end to the distal end along the fifth guide rail 171; then, the fine - grinding wheel in the edge spindle 45 rotates at a high speed, and contacts the distal end of the first edge of workpiece C under the drive of the lifting drive unit and the transverse movement drive unit. When workpieces C and D are driven by the third grinding carrier 172 to move from the proximal end to the distal end along the fifth guide rail 171 and pass by the fine - grinding wheel once, the edge spindle 45 completes the chamfering operation from the distal end to the proximal end of the first edge of workpiece C.
[0154] Subsequently, workpiece C and workpiece D are driven by the third grinding carrier 172 to move from the distal end to the proximal end of the fifth guide rail 171. At the same time, the fine grinding wheel is driven by the lifting drive unit and the lateral drive unit to move and contact the proximal end of the first edge of workpiece D. When workpiece C and workpiece D are driven by the third grinding carrier 172 to move from the distal end to the proximal end of the fifth guide rail 171 and pass the fine grinding wheel once, the edge spindle 45 completes the chamfering operation from the proximal end to the distal end of the first edge of workpiece D.
[0155] Next, workpiece C and workpiece D are driven by the third grinding carrier 172 to move from the proximal end to the distal end of the fifth guide rail 171. At the same time, the edge spindle 45 is flipped 180° to a symmetrical position under the action of the flip unit to achieve the switching from the first edge to the second edge; the fine grinding wheel is driven by the lifting drive unit and the lateral drive unit to move and contact the distal end of the second edge of the workpiece D. When workpiece C and workpiece D are driven by the third grinding carrier 172 to move from the proximal end to the distal end of the fifth guide rail 171 and pass the fine grinding wheel once, the edge spindle 45 completes the chamfering operation from the distal end to the proximal end along the second edge of the workpiece D.
[0156] Finally, workpiece C and workpiece D are driven by the third grinding carrier 172 to move from the distal end to the proximal end of the fifth guide rail 171. At the same time, the fine grinding wheel is driven by the lifting drive unit and the lateral drive unit to move and contact the proximal end of the second edge of workpiece C. When workpiece C and workpiece D are driven by the third grinding carrier 172 to move from the distal end to the proximal end of the fifth guide rail 171 and pass the fine grinding wheel once, the edge spindle 45 completes the chamfering operation from the proximal end to the distal end of the second edge of workpiece C.
[0157] In this way, the chamfering operation of the first edge and the second edge of the workpiece C and the first edge and the second edge of the workpiece D is completed. It should be noted that the above embodiment is only an exemplary description, and the actual operation sequence is determined according to actual production requirements, and this application does not impose any restrictions on this.
[0158] As mentioned above, when the edge spindle 45 is used to chamfer the second-specification workpiece, the edges on the same side of the two second-specification workpieces can be chamfered in batches first, and then flipped 180° to a symmetrical position under the action of the flip unit, and then the edges on the other side of the two second-specification workpieces can be chamfered in batches. In this way, the flip unit only needs to flip once to complete the chamfering operation of the two second-specification workpieces, which simplifies the equipment structure and further improves the work efficiency.
[0159] The following is a detailed description of the execution process of the workpiece cutting and grinding integrated device in the above embodiment in conjunction with the accompanying drawings:
[0160] First, use Figure 5b the hoisting mechanism shown to load the workpieces of the first specification. At this time, under the action of the horizontal hoisting drive unit and the hoisting and lifting mechanism, the hoisting mechanism moves to the position of the workpieces of the first specification on the stacking vehicle, and then uses the second suction cup assembly to transfer two workpieces of the first specification to the first loading and unloading station and / or the second loading and unloading station in batches for subsequent cutting operations.
[0161] Then, use the first suction cup assembly in the workpiece transporting device as shown in Figures 4a to 4b to adsorb the top surface of the workpiece of the first specification, and cooperate with the gantry to transfer and place the workpiece of the first specification on the first cutting carrier near the proximal end of the first cutting station or the second cutting carrier near the proximal end of the second cutting station as shown in Figure 8 The first cutting carrier or the second cutting carrier is clamped by the first clamping unit and the second clamping unit, and the workpiece of the first specification is fixed under the action of their respective clamping parts for cutting operations; use Figure 7a the first cutting device or the second cutting device shown to perform cutting operations on the workpiece of the first specification. The first cutting device or the second cutting device drives the vertical wire saw to move from the distal end to the proximal end along the second guide rail until it completely penetrates the workpiece of the first specification, forming workpieces A and B as shown in Figure 10 Then, the first clamping unit and the second clamping unit move horizontally along the transverse guide rail to a separated state, so that the first clamping unit carries workpiece A and the second clamping unit carries workpiece B and is separated relatively horizontally to leave a wire withdrawing space. At this time, the vertical wire saw moves from the proximal end to the distal end along the longitudinal direction on the first guide rail or the second guide rail with the first cutting device or the second cutting device to complete the withdrawal of the cutting wire.
[0162] Next, the first clamping unit and the second clamping unit drive the cutting surfaces of the carried workpiece A and workpiece B to be switched from vertical to horizontal under the drive of their respective flipping mechanisms, forming the state as shown in Figure 11 Then, the clamping parts of the first clamping unit and the second clamping unit release workpiece A and workpiece B under the drive of their respective rotating mechanisms and clamping drive units, and the transporting device transfers workpiece A and workpiece B to the first grinding station or the second grinding station in sequence in cooperation with the gantry for subsequent surface grinding operations. Subsequently, the first clamping unit and the second clamping unit are flipped again to the state as shown in Figure 8 awaiting cutting operations on the next workpiece of the first specification.
[0163] When performing a surface grinding operation on workpiece A and workpiece B on the first grinding carrier or the second grinding carrier at the proximal end of the first grinding station or the second grinding station, the first grinding carrier or the second grinding carrier presses workpiece A and workpiece B in cooperation with the backrest and the lateral pressing assembly, and drives workpiece A and workpiece B to move from the proximal end to the distal end along the third guide rail or the fourth guide rail. At this time, the first surface spindle and the second surface spindle of the first surface grinding device or the third surface spindle and the fourth surface spindle of the second surface grinding device act simultaneously to perform a surface grinding operation on the cutting surfaces of workpiece A and workpiece B, forming workpiece C and workpiece D. The workpiece C and workpiece D are sequentially transported to the chamfering position as shown in Figure 14 for chamfering the first edge and the second edge.
[0164] When performing a chamfering operation on workpiece C and workpiece D on the third grinding carrier at the proximal end of the third grinding station, the third grinding carrier presses workpiece C and workpiece D in cooperation with the backrest and the lateral pressing assembly, and drives workpiece C and workpiece D to move from the proximal end to the distal end along the fifth guide rail for a first grinding, and then move from the distal end to the proximal end along the fifth guide rail for a second grinding. In cooperation therewith, the fine grinding wheel of the edge spindle in the chamfering device chamfers the first edge of workpiece C and the first edge of workpiece D in sequence under the drive of the lifting drive unit and the transverse drive unit, then rotates 180° to the symmetric position under the action of the flipping unit, and then chamfers the second edge of workpiece D and the second edge of workpiece C in sequence.
[0165] Finally, the workpiece C and workpiece D that have completed the chamfering operation are sequentially transported to the first loading and unloading station or the second loading and unloading station by using the workpiece transporting mechanism; the Figure 5b shown hoisting mechanism unloads workpiece C and workpiece D in sequence.
[0166] In summary, in order to overcome the technical problems existing in the above-mentioned related technologies that the cutting equipment and the grinding equipment are used separately to perform cutting, grinding and chamfering on the rectangular silicon rods, resulting in complicated equipment, inconvenient operation and low processing efficiency, the present application provides a workpiece cutting and grinding integrated equipment, which integrates the cutting device, the grinding device, and the chamfering device in a parallel manner into one device with a layout of cutting on both sides and grinding on the inside, and vertically cuts the workpiece in half by using the first and second cutting stations arranged in parallel, grinds the cut surface of the workpiece by using the first and second grinding stations, and chamfers the workpiece by using the third grinding station, thereby realizing the integration of multiple processes of cutting in half, grinding and chamfering of the rectangular silicon rods. The present application avoids possible collision of the workpiece during the cutting process by vertically cutting and then separating the workpiece in half, thereby improving the quality of the workpiece processing operation. By providing a detachable and flippable cutting carrier, the workpiece is avoided from being flipped in mid-air by the transport device, so that the workpiece can be supported more stably for adsorption and transfer. By providing a flippable chamfering device, the chamfering operation of the edges of different workpieces is realized, which simplifies the equipment structure and optimizes the operation sequence. Finally, the present application realizes automated transportation and automated loading and unloading through the cooperation of the first loading and unloading station, the second loading and unloading station and the transport mechanism, thereby further improving work efficiency.
[0167] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
