Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting, in particular to a loading and unloading buffer device and a wire cutting machine for wire cutting. Background Art

[0002] In the field of online cutting technology, taking photovoltaic silicon rods as an example, making silicon rods into silicon wafers generally requires processes such as cutting, squaring, grinding, and slicing. The slicing operation is completed by a slicer. The silicon rod is bonded to the crystal tray, and the crystal tray is clamped by a clamping device. Then, the silicon rod is driven by the feeding mechanism to move relative to the cutting wire mesh to achieve slicing. When the existing slicer is working, it is usually first used to transport a silicon rod into the slicer by a transfer device. When the silicon rod is cut, the transfer device is used to remove the cut silicon rod. When loading is required in the cutting chamber and the external robot cannot provide the silicon rod, the cutting chamber cannot obtain the workpiece and cannot cut; when unloading is required in the cutting chamber and the external robot cannot remove the silicon rod in time, the workpiece in the cutting chamber cannot be removed in time, and other operations cannot be performed in the cutting chamber. Therefore, the external transfer device needs to be waiting at all times, otherwise there will be a problem of low cutting efficiency. Utility Model Content

[0065] like Figure 1 As shown, and reference Figures 2 to 8 , an embodiment of the utility model provides a loading and unloading cache device 100. The loading and unloading cache device 100 includes a support unit 10 and a cache unit 20. The support unit 10 is used to support the weight of the entire device and the workpiece, and to connect with other parts of the wire cutting machine. The support unit is provided with a loading and unloading station, that is, a position on the support unit is used for loading and unloading, which is a loading and unloading station. The cache unit 20 has at least two storage parts. The cache unit 20 is movably mounted on the support unit 10 to drive each storage part to move to the loading and unloading station or leave the loading and unloading station.

[0066] In this embodiment of the present invention, the loading and unloading buffer device 100 includes two storage sections, at least one of which is used to receive cut workpieces, while the other section can be used to temporarily store uncut workpieces. When loading workpieces into the cutting chamber, the storage section can provide the workpieces, facilitating cutting. When unloading workpieces from the cutting chamber is required, the workpieces can be placed on the storage section, facilitating other operations within the cutting chamber, enabling timely loading and unloading, and improving the cutting efficiency of the wire cutting machine.

[0067] Moreover, in an embodiment of the present invention, one of the storage sections is used to receive workpieces being cut, serving as a temporary unloading section, while the remaining storage sections can be used to temporarily store uncut workpieces, serving as temporary loading sections. During operation, the cut workpieces can be temporarily stored in the temporary unloading section. The buffer unit is moved to move another storage section to the loading and unloading station, and then the uncut workpieces in the other storage section are allowed to enter the cutting chamber assembly 200 of the wire cutting machine for cutting, while the storage section becomes a temporary unloading section. At the same time, the staff or loading and unloading equipment can remove the cut workpieces from the loading and unloading buffer device 100 at an appropriate time while the wire cutting machine is cutting. At this time, the temporary unloading section becomes a temporary loading section, and uncut workpieces are loaded onto the storage section. When the wire cutting machine is first started, uncut workpieces can be temporarily stored in all the storage sections. Then, the wire cutting machine is operated, and the workpieces in one storage section are allowed to enter the cutting chamber assembly 200 for cutting, making the storage section a temporary unloading section.

[0068] The setting of the loading and unloading buffer device 100 allows the wire cutting machine to place the cut workpiece on the loading and unloading buffer device 100 in a timely manner without having to stop or wait for a long time after cutting, and to place the uncut workpiece from the loading and unloading buffer device 100 into the cutting chamber assembly 200 for cutting, so that the wire cutting machine can cut continuously. That is, the wire cutting machine can make the next cut in a timely manner after completing one cut, which is beneficial to improving the cutting efficiency of the wire cutting machine and shortening the waiting time of the wire cutting machine. When the staff or loading and unloading equipment loads and unloads materials to the loading and unloading buffer device 100, it will not have any impact on the cutting of the wire cutting machine, and it is also beneficial for the staff or loading and unloading equipment to arrange their work reasonably. Therefore, the loading and unloading buffer device 100 of the embodiment of the utility model is a product for use with a diamond wire silicon wafer slicer. The loading and unloading buffer device 100 is designed with a storage portion that can cache the workpieces to be processed and the processed workpieces. The movement of the storage portion realizes the switching between loading and unloading, greatly improving the automatic loading and unloading efficiency of robots and the like for the cutting chamber assembly 200, which is beneficial to the continuity of cutting of the cutting chamber assembly 200.

[0069] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, there are two storage sections, and the cache unit 20 has a first movement position and a second movement position. In the first movement position, one storage section is at the loading and unloading station, and in the second movement position, the other storage section is at the loading and unloading station. In other words, the cache unit 20 preferably has two storage sections, wherein the loading and unloading station always has one storage section, and after the uncut workpiece on the storage section enters the cutting chamber assembly 200, the storage section serves as a temporary storage section for unloading, waiting there. After receiving the workpiece after cutting, the other storage section is moved to the loading and unloading station. When there are three or more storage sections, such an operation can also be performed, so that one storage section waits to receive the workpiece after cutting after loading the cutting chamber assembly 200 at the loading and unloading station. There are two storage parts, which can make the loading and unloading buffer device 100 and the wire cutting machine compact and small in size. While it is beneficial to improve the cutting efficiency of the wire cutting machine and shorten the waiting time of the wire cutting machine, it is also beneficial for the staff or loading and unloading equipment to load and unload materials to the loading and unloading buffer device 100 in a timely, reasonable and orderly manner. This is beneficial to the continuous work of wire cutting and provides the possibility for the staff or loading and unloading equipment to work reasonably and flexibly.

[0070] In some embodiments of the present invention, at least two storage sections include: a loading storage section that is only used to receive and store workpieces to be cut, and a unloading storage section that is only used to receive and store workpieces that have been cut. That is, the cache unit 20 includes two types of storage sections, namely an unloading storage section and a loading storage section, wherein the unloading storage section is used to receive workpieces that have been cut, and the loading storage section is used to temporarily store uncut workpieces to be cut, that is, for receiving workpieces placed externally. When in use, workpieces are only placed on the loading storage section for loading, and workpieces that have been cut are removed from the unloading storage section for unloading. Dividing the storage section into a dedicated loading section and a dedicated unloading section facilitates docking with external equipment such as a manipulator, which is conducive to improving the automation and accuracy of control, simplifying the control, and preventing docking failures. In this embodiment, there is only one unloading storage section and one loading storage section.

[0071] At the appropriate time, for example, while the wire saw is cutting, workers or loading and unloading equipment can remove the cut workpiece from the dedicated unloading storage section. The unloading storage section then waits to receive the next cut workpiece. Once the workpiece on the loading storage section enters the cutting chamber, uncut workpieces can be placed on the loading storage section at any time.

[0072] In some embodiments of the present invention, Figure 1 As shown, a workpiece, usually a silicon rod 62, needs to be mounted on a wafer support 61. Each storage portion includes a support rail 21 for supporting the wafer support 61.

[0073] In some embodiments of the present invention, the crystal support 61 includes a crystal support plate and a connecting block provided on the upper side of the crystal support plate. The lower side of the crystal support plate is used to bond the silicon rod 62. The upper side of the crystal support plate and the connecting block form a clamping groove with an opening facing upward, which extends along the length direction of the crystal support 61 and passes through the crystal support 61. In other embodiments of the present invention, the upper side of the crystal support plate and the connecting block form two slide grooves, which are respectively located on both sides of the crystal support 61. Each slide groove extends along the length direction of the crystal support 61, and the opening of each slide groove faces one side of the crystal support 61. In still other embodiments of the present invention, the crystal support 61 has both a clamping groove and a slide groove.

[0074] In some embodiments of the present invention, Figure 1 、 Figure 4 As shown, each storage section includes two parallel support rails 21 spaced apart from each other. All support rails 21 are arranged in parallel. The two support rails 21 are inserted into two respective chute slots. Using two support rails 21 ensures smoother movement of the wafer holder 61. In some embodiments of the present invention, each storage section includes one support rail 21, which is inserted into the clamping slot. Multiple support rails 21 are arranged in parallel.

[0075] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the cache unit 20 also includes a base assembly and a workpiece support assembly. The base assembly is movably arranged on the support unit 10. A driving unit 40 and a guide rail 13 are provided on the support unit 10. The guide rail 13 is perpendicular to the support rail 21, that is, the extension direction of the workpiece is perpendicular to the movement direction of the cache unit 20, which is beneficial to the arrangement of the cache unit 20, so that the loading and unloading cache device 100 has a compact structure and occupies a small space. The base assembly includes a bracket 22, and the bracket 22 is mounted on the guide rail 13 through a slider; the driving unit 40 is provided on the support unit 10, and is configured to drive the bracket 22 to move along the guide rail 13.

[0076] In an embodiment of the present utility model, the base assembly serves as the bottom skeleton of the cache unit 20, carrying and installing the workpiece support assembly, as well as the corresponding protective limit unit, position detection unit, etc. The workpiece support assembly is used to carry and position the crystal holder 61 and the workpiece. The guide rail 13 can have the functions of positioning, guiding and supporting. The guide rail 13 is preferably a linear guide rail. Since the friction resistance of the slider on the linear guide rail is extremely small when sliding and it is installed horizontally, the power output requirement when the slider slides is also low. The drive unit 40 can be a cylinder drive unit, which outputs power to achieve the switching action of the position of the cache unit 20. The cylinder drive unit is a cylinder, including a cylinder body fixedly mounted on the support unit 10, and the cylinder drive rod is the output part of the drive unit 40, which is connected to the bracket 22 through a floating joint.

[0077] In some embodiments of the present invention, the workpiece support assembly includes a plurality of parallel, spaced-apart upper plates and a plurality of support plates. Two support rails 21 are provided on two adjacent upper plates in each storage section, and corresponding support rails 21 are provided on the edges of each upper plate adjacent to the other upper plate. Each support plate can be arranged vertically, with the upper end of each support plate connected to an upper plate and the lower end mounted on the base assembly.

The upper end of each intermediate support plate 55 is connected to the middle of an intermediate upper plate 54; a plurality of first reinforcing ribs 50 are disposed between each side of the intermediate support plate 55 and the corresponding intermediate upper plate 54.

[0079] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the lower end of each support plate is mounted on the bottom support assembly via a lower flat plate. For example, the multiple lower flat plates include a first lower flat plate 53, a second lower flat plate 59, and at least one intermediate lower flat plate 56, with the intermediate lower flat plate 56 located between the first lower flat plate 53 and the second lower flat plate 59. The lower end of the first support plate 51 is connected to the edge of the first lower flat plate 53 away from the other lower flat plates; a plurality of second reinforcing ribs 63 are disposed between the first support plate 51 and the first lower flat plate 53.

Specifically, the water receiving tray 30 can prevent the water droplets remaining on the surface of the workpiece from causing damage to the components below, such as the cylinder and proximity switch, and from dripping onto the ground to cause pollution. For example, there is one water receiving tray 30, which is arranged on the lower side of all storage parts. In other embodiments of the present invention, there are multiple water receiving trays 30, and each water receiving tray 30 is arranged on the lower side of a storage part. Each water receiving tray 30 is arranged between two support plates. The water receiving tray 30 is made of stainless steel to prevent rust. There is a drainage hole 31 on the bottom surface of the water receiving tray 30, and the internal water is discharged to the designated area through the drainage hole 31 and the corresponding pipeline.

[0086] In some embodiments of the present invention, Figure 1 and Figure 2As shown, a limit unit and a position detection unit are provided on the support unit 10. The position detection unit is configured to detect the position of the buffer unit 20, and the limit unit is configured to limit the travel of the buffer unit 20. For example, the limit unit includes two limit blocks 14, and the buffer unit 20 includes a limit post 24 that contacts the limit blocks 14, and the limit post 24 is disposed between the two limit blocks 14. The two limit blocks 14 are configured to switch the buffer unit 20 between a first movement position and a second movement position. The position detection unit includes two proximity switches 15, one proximity switch 15 is configured to detect whether the buffer unit 20 has moved to the first movement position, and the other proximity switch 15 is configured to detect whether the buffer unit 20 has moved to the second movement position. The limit blocks 14 are used to limit the switching position and alignment of the buffer unit 20. During installation, the limit blocks 14 and the proximity switches 15 can be adjusted to the appropriate positions before installation, which facilitates accurate feedback of the current position of the buffer unit 20.

[0087] In some embodiments of the present invention, the position-limiting block 14 has a buffering function. For example, the position-limiting block 14 includes a block body and a buffer pad provided on the surface of the block body.

[0088] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the support unit 10 comprises a support frame 11 and a plurality of legs 12. The buffer unit 20 is movably mounted on the support frame 11. The legs 12 are disposed on the underside of the support frame 11. The support frame 11 is mounted to the upper ends of the legs 12 at various locations via height adjustment units. The legs 12 have mounting holes for bolting to the microtome fluidic system frame.

[0089] The height adjustment unit includes a jackscrew 16 mounted on the support frame 11 and in contact with the support legs 12. Furthermore, after the height and levelness of the support frame 11 are adjusted, the support frame 11 and the support legs 12 are fixed together via screws. In some embodiments of the present invention, one of the support frame 11 and the support legs 12 is provided with a positioning guide post, and the other is provided with a guide hole. The positioning guide post is vertically arranged and inserted into the guide hole.

[0090] The present invention also provides a wire cutting machine. Figure 8As shown, the wire EDM includes a cutting chamber assembly 200 and the loading and unloading buffer device 100 described in any of the above-mentioned embodiments. A wire EDM is a device used for cutting hard and brittle material rods, such as single crystal silicon rods, polycrystalline silicon rods, sapphire rods, and magnetic rods. Wire EDMs offer advantages such as high efficiency, high production capacity, and high precision. Their principle is to achieve cutting by rubbing a high-speed cutting wire against the workpiece. Wire EDMs often use single or multiple diamond wires to cut, square, and slice silicon materials, thereby obtaining the corresponding silicon wafers or silicon materials. The cutting chamber assembly 200, used for cutting, comprises a cutting roller, a diamond wire mounted on the cutting roller, and a lifting device that moves the workpiece up and down. The lifting device moves the workpiece downward, where it comes into contact with the diamond wire and is cut by the diamond wire. The cutting chamber assembly 200 has a loading and unloading port. The loading and unloading buffer device 100 is located outside the loading and unloading port, with the storage portion corresponding to the loading and unloading port when the loading and unloading station is in operation.

[0091] In this embodiment, the loading and unloading buffer device 100 is used to temporarily store the workpiece or form a temporary unloading storage portion for loading and unloading the workpiece to the cutting chamber assembly 200. That is, the loading and unloading buffer device 100 provides services for the movement of the workpiece to the cutting station, and when the workpiece is cut at the cutting station, it provides services for the workpiece to be unloaded from the wire cutting device. That is, after the wire cutting machine cuts the silicon rod 62, it does not need to stop or wait for a long time, and the cut workpiece is placed on the loading and unloading buffer device 100 in time, and the uncut workpiece is placed from the loading and unloading buffer device 100 into the cutting chamber assembly 200 for cutting. That is, after completing one cut, the wire cutting machine can perform the next cut in time, which is beneficial to improving the degree of automation of the wire cutting machine, improving the cutting efficiency of the wire cutting machine, improving the loading and unloading transportation efficiency of the wire cutting machine, and shortening the waiting time of the wire cutting machine. Furthermore, the staff or loading and unloading equipment do not need to wait for a special workpiece to be picked up and placed next to the wire cutting machine. The staff or loading and unloading equipment can, according to their own plan, remove the workpiece that has been cut from the loading and unloading buffer device 100 and install the workpiece that has not been cut while the wire cutting machine is cutting. This will not affect the cutting of the wire cutting machine and is also conducive to the staff or loading and unloading equipment to arrange their work reasonably, that is, it is conducive to saving the handling efficiency of the loading and unloading robot. The staff can load and unload the loading and unloading buffer device 100 without loading and unloading the cutting chamber assembly 200, which is farther away from the cutting area, greatly reducing safety hazards.

[0092] In some embodiments of the present invention, the wire saw is a slicer. It can slice silicon rods 62 and the like. For example, crystalline silicon, the primary raw material for solar panels, requires processes such as squaring and slicing before it can be made into crystalline silicon wafers. The slicing process is performed using a slicer, which slices the squared silicon rods 62 into silicon wafers.

[0093] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
