Description

Technical Field

[0001] The present invention relates to a processing device. Background Art

[0002] For example, when processing a substrate (hereinafter sometimes referred to as a workpiece) such as a semiconductor material to be singulated into a wafer shape, a circular blade is sometimes used. As a method for stably rotating a blade, a hub blade is known that holds the blade on a hub. The hub blade, for example, comprises a hub constructed of an aluminum alloy and an electroformed blade body formed by nickel plating on one side of the hub. The hub blade is a blade formed by integrally connecting the hub and the electroformed blade body.

[0003] By minimizing the protrusion of the electroformed blade body, the blade body's tendency to meander or tilt can be controlled to a relatively small extent. Consequently, high-quality workpiece processing can be achieved using the electroformed blade body. Furthermore, the hub blade can be automatically replaced by gripping and transporting the hub (hereinafter sometimes referred to as "manipulation") the hub blade (see, for example, Patent Document 1).

[0004] Patent Document 1: Japanese Patent Publication No. 5-345281

[0005] However, the electroformed blade bodies of wheel hub inserts use nickel as a binder, for example. Therefore, these electroformed blade bodies are difficult to apply to machining difficult-to-cut materials, for example. Furthermore, when the workpiece is thick, the protrusion of the electroformed blade body must be large. Therefore, it is difficult to apply electroformed blade bodies with a small protrusion to machining thicker workpieces. This hinders the expansion of the workpieces for which wheel hub inserts can be applied.

[0006] As blades for machining workpieces, hubless blades are known, which are blades without a hub. The blade body of a hubless blade may have abrasive particles dispersed in a binder phase composed of, for example, a resin material (resin). Hubless blades can be manufactured using a variety of blade materials. Furthermore, hubless blades are also suitable for machining difficult-to-cut materials, for example, because they promote wear.

[0007] However, the hub as the holding position is not provided on the hub-free blade. Therefore, it is difficult to realize the automation of the replacement of the hub-free blade. This can hinder the expansion of the object workpiece that can be efficiently mass-produced by the hub-free blade. Summary of the Invention

[0008] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a processing device capable of enlarging a target workpiece.

[0009] In order to solve the above problems, the present invention proposes the following solutions.

[0010] <1> One aspect of the present invention involves a processing device including: a hubless blade having a blade body and a clamping portion, wherein the clamping portion is connected to one surface of the blade body and can be manipulated by being grasped; a blade fixing portion having a first flange that can be engaged with a main shaft; and a replacement portion that can achieve automatic replacement by installing and removing the first flange relative to the main shaft.

[0011] According to the above <1> In the processing device, the hubless blade includes a blade body and a clamping portion. The clamping portion is connected to one side of the blade body and can be manipulated by being gripped. Thus, when the processing device uses the hubless blade to process a workpiece, the hubless blade can be manipulated by gripping the clamping portion. This allows for automated replacement of the hubless blade, thereby expanding the range of applicable workpieces.

[0012] Here, in order to manage the protrusion of the hubless blade, it is necessary to replace the blade fixing part so that the outer diameter of the blade fixing part is changed according to the outer diameter of the worn hubless blade. Furthermore, with respect to the blade fixing part, sometimes due to repeated installation and removal of the hubless blade, the hubless blade contacts the end face of the blade fixing part, causing scratches on the end face. In this case, although it is possible to repair it to some extent by modifying the end face in contact with the hubless blade, if the scratch is difficult to repair, it is necessary to replace the blade fixing part. Furthermore, it is necessary to install and remove the blade fixing part when cleaning the spindle.

[0013] Therefore, the processing device is provided with a replacement unit. The replacement unit can realize automatic replacement by attaching and detaching the blade fixing unit relative to the main shaft. Thus, the protrusion amount of the hubless blade can be managed by automatically replacing the blade fixing unit.

[0014] In addition, when the scar on the end face of the blade fixing portion is difficult to repair, the blade fixing portion can be automatically replaced by the replacement portion. Further, when cleaning the main shaft, the blade fixing portion can be automatically installed and removed by the replacement portion.

[0015] <2> In the above <1> In the processing device, the replacement portion may be arranged on a rotatable rotating table.

[0016] According to the above <2> The processing device can be made compact by arranging the replacement portion on a rotatable rotating table.

[0017] <3> In the above <1> or <2> In the processing device, the replacement part includes a tool head, a first assembly and disassembly fixture and a second assembly and disassembly fixture, the tool head can be inserted into the first assembly and disassembly fixture, the second assembly and disassembly fixture is combined with the first assembly and disassembly fixture, and the second assembly and disassembly fixture can be combined with the first flange.

[0018] <4> In the above <1> to <3> Any one of the above-mentioned processing devices may include a control device for controlling the replacement unit.

[0019] According to the present invention, it is possible to expand the scope of target workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] [First embodiment]

[0044] Figure 1 It is a perspective view showing the processing device according to the first embodiment. Figure 2 It is a plan view showing a tray portion included in the processing apparatus. Figure 3 It is a perspective view for explaining the structure of the hubless blade and the blade fixing portion. Figure 4 It is a cross-sectional view showing a state where the hubless blade is fixed by the blade fixing portion.

[0045] The processing device 1 processes a workpiece (not shown) using a hubless blade 10. Figure 1 As shown, the processing device 1 includes a processing unit 3, a tray unit 4 and a stocker unit 5. The processing unit 3 includes a workbench 21 (see Figure 1 )、spindle unit 22 (refer to Figure 2 and Figure 4 ) and the blade fixing portion 23 (refer to Figure 2 and Figure 4 The processing device 1 can process a workpiece by mixing the hubless blade 10 with other blades (for example, the hubless blade 100 described later or a well-known hub blade, etc.).

[0046] The workbench 21 adsorbs and holds a workpiece not shown in the figure. Figure 4 As shown, the spindle unit 22 includes a spindle (rotating shaft) 221. The hubless insert 10 is fixed to the spindle 221 via an insert fixing portion 23. In the processing unit 3, the hubless insert 10 processes a workpiece held by suction on the table 21.

[0047] Figure 5 It means along Figure 2 Cross-sectional view taken along line VV.

[0048] like Figures 2 to 5 As shown, the blade fixing portion 23 is fixed by clamping the hubless blade 10. For example, Figure 3 As shown, the blade fixing portion 23 includes a first flange 231 and a nut 232. Figure 5 As shown, the shaft portion 233 of the first flange 231 is engaged with the main shaft 221, and the first flange 231 is fixed to the main shaft 221 by flange bolts 237. Figure 5 As shown, the first flange 231 has a flange body 234 and an outer stopper 235 in addition to the shaft portion 233 .

[0049] The flange body 234 is provided on the shaft portion 233. The outer stopper 235 protrudes from the outer periphery of the flange body 234 toward the hubless blade 10. The outer peripheries of the flange body 234 and the outer stopper 235 form the outer periphery 231a of the first flange 231.

[0050] like Figure 3As shown, the hubless blade 10 includes a blade body 11 and a base (Taiwan alloy) 12. The blade body 11 is annular. A mounting hole 13 is provided in the center of the blade body 11 and the base 12, and the shaft portion 233 of the first flange 231 is inserted into the mounting hole 13. The blade body 11 has abrasive grains dispersed in a binder phase composed of, for example, a resin material (resin).

[0051] The hubless blade 10 is engraved with blade information (barcode information). Examples of the blade information include the outer diameter, binder phase, thickness, abrasive grain type, grain size, concentration, and serial number of the blade body 11. The blade information can be engraved on the blade body 11 or on the base 12.

[0052] The base 12 is constructed in an annular shape. The base 12 comprises: a connecting portion 121 connected to one surface of the blade body 11; and a clamping portion 122 provided on the side of the connecting portion 121 opposite to the blade body 11 (in other words, on the side of the nut 232). Figure 4 As shown, the outer diameter D of the connecting portion 121 is 121 Smaller than the outer diameter D of the blade body 11 11 , and the outer diameter D of the outer periphery 231a of the first flange 231 231 In addition, the outer diameter D of the clamping portion 122 is 122 Smaller than the outer diameter D of the connecting portion 121 121 .

[0053] The clamping portion 122 is, for example, held by a second replacement portion (not shown). Therefore, the second replacement portion can hold the clamping portion 122, thereby manipulating the hubless blade 10. By holding the clamping portion 122 and manipulating the hubless blade 10, the mounting hole 13 can be engaged with the shaft portion 233 of the first flange 231, thereby mounting the hubless blade 10 on the shaft portion 233. Furthermore, the clamping portion 122 can be held by the second replacement portion, and the hubless blade 10 can be removed from the shaft portion 233. This allows automated replacement of the hubless blade 10.

[0054] The nut 232 is threadedly engaged with the external thread 236 of the shaft portion 233 in the first flange 231 .

[0055] Thus, the hubless blade 10 is clamped by the first flange 231 and the nut 232 of the blade fixing portion 23, and is thereby fixed by the blade fixing portion 23. Furthermore, the blade fixing portion 23 is fixed to the spindle 221. Therefore, the hubless blade 10 is fixed to the spindle 221 via the blade fixing portion 23. The nut 232 can be replaced by a second replacement portion (not shown).

[0056] Here, the insert body 11 is worn by machining the workpiece, and the protrusion amount I of the insert body 11 from the base 12 becomes smaller. The protrusion amount I affects the machining quality of the workpiece. In the hubless insert 10, the outer diameter D of the connecting portion 121 can be changed. 121 and the outer diameter D of the outer periphery 231a of the first flange 231 231 to adjust the protrusion amount I.

[0057] like Figure 2 As shown, the tray unit 4 includes a rotating table 51, a first replacement unit 52, and a second replacement unit (not shown). The rotating table 51 is rotatably supported on the tray unit 4. The first replacement unit 52 and the second replacement unit are provided on the rotating table 51. The first replacement unit 52 corresponds to the replacement unit in the present invention.

[0058] Figure 6 It is a perspective view showing a tool head of a first replacement portion included in the machining apparatus. Figure 7 This is an exploded perspective view of a first replacement jig and a second replacement jig of a first replacement unit included in a processing apparatus.

[0059] like Figures 4 to 7 As shown, the first replacement part 52 can realize the automatic installation and removal of the blade fixing part 23 (specifically the first flange 231) relative to the main shaft 221. That is, the first replacement part 52 can automatically replace the first flange 231 (that is, the blade fixing part 23). Figure 7 As shown, the first replacement part 52 includes, for example, a cutter head 54 (see Figure 6 ), a first assembly and disassembly fixture 55 and a second assembly and disassembly fixture 56.

[0060] Figure 8 This is a perspective view showing a state where the flange bolts are removed using the cutter head of the first replacement unit.

[0061] like Figure 5 、 Figure 6 and Figure 8 As shown, the cutter head 54 is provided so as to be able to advance and retreat relative to the shaft portion 233 of the first flange 231. The front end portion 54a of the cutter head 54 can be inserted into the recess 237a of the flange bolt 237 (see Figure 5 ). With the tip 54a of the cutter head 54 inserted into the recess 237a of the flange bolt 237, the cutter head 54 is rotated. This allows the flange bolt 237 to be removed from the spindle 221. A plunger 57 is embedded in the tip 54a of the cutter head 54. Therefore, the plunger 57 can retain the flange bolt 237 removed from the spindle 221 on the tip 54a of the cutter head 54.

[0062] Figure 9 This is a cross-sectional view showing a portion of the first replacement unit. Figure 10It is a perspective view showing a state where the first flange is temporarily stored on the buffer stage.

[0063] like Figure 7 and Figure 9 As shown, an external thread 58 is provided at the front end of the first mounting and disassembly jig 55. The external thread 58 of the first mounting and disassembly jig 55 is threadedly engaged with the first internal thread 59 of the second mounting and disassembly jig 56. Furthermore, the second internal thread 61 of the second mounting and disassembly jig 56 is threadedly engaged with the external thread 236 of the first flange 231. The external thread 236 of the first flange 231 is provided on the outer circumference of the shaft portion 233. Therefore, the first flange 231 can be removed from the main shaft 221 by retracting the first and second mounting and disassembly jigs 55 and 56 from the first flange 231. The first flange 231 removed from the main shaft 221 can be temporarily stored on the buffer stage 63.

[0064] The first replacement unit 52 can remove the first flange 231 from the main shaft 221 and then install a first flange with a different outer diameter on the main shaft 221. The first replacement unit 52 can fix the first flange installed on the main shaft 221 to the main shaft 221 using the flange bolts 237. The first flange 231 temporarily stored on the buffer stage 63 is returned to the main shaft 221. Figure 1 In the stocker portion 5 shown. Thus, the first flange 231 can be automatically replaced by the first replacement portion 52.

[0065] In the first embodiment, the first replacement portion 52 includes two jigs, the first attaching and detaching jig 55 and the second attaching and detaching jig 56 . However, the first attaching and detaching jig 55 and the second attaching and detaching jig 56 may be integrated into one jig.

[0066] Figure 11 It is a cross-sectional view illustrating a modified example in which the first flange is removed from the main shaft.

[0067] like Figure 11 As shown, the front end 54a of the cutter head 54 is inserted into the recess 237a of the flange bolt 237, and the flange bolt 237 is loosened halfway. The first assembly and disassembly jig 55 is mounted on the second assembly and disassembly jig 56, and the second assembly and disassembly jig 56 is mounted on the first flange 231. Next, the flange bolt 237 is loosened using the cutter head 54, and the first flange 231 and flange bolt 237 are removed from the main shaft 221 in unison using the first assembly and disassembly jig 55 and the second assembly and disassembly jig 56. This allows the first flange 231 to be removed from the main shaft 221. Since the first flange 231 and flange bolt 237 can be removed in unison, automated disassembly efficiency is improved.

[0068] The replacement of the first flange by the first replacement unit 52 is performed, for example, through the following processes (1) to (5).

[0069] (1) With the front end portion 54 a of the cutter head 54 inserted into the recess 237 a of the flange bolt 237 , the cutter head 54 is rotated to loosen the flange bolt 237 halfway.

[0070] (2) The first attachment and detachment jig 55 and the second attachment and detachment jig 56 are retracted from the first flange 231 , thereby removing the first flange 231 and the flange bolts 237 from the main shaft 221 .

[0071] (3) The disassembled first flange 231 and flange bolts 237 are temporarily stored on the buffer stage 63 .

[0072] (4) Install the first flange 231 and the flange bolts 237 on the main shaft 221 by performing the operations opposite to (1) and (2).

[0073] (5) The first flange 231 and the flange bolts 237 stored on the buffer stage 63 are conveyed to the stocker unit 5 .

[0074] In addition, after the first flange 231 is pulled out from the main shaft 221 , the flange bolts 237 can be loosened using the cutter head 54 to remove the first flange 231 from the main shaft 221 .

[0075] The above steps can be performed by the first replacement unit controlled by a known control device. The above control device can also control the rotating table.

[0076] like Figure 3 As shown, the second replacement part (not shown) can hold the clamping part 122 of the base 12 and install and remove the base 12 relative to the blade fixing part 23 (specifically, the first flange 231), and can automatically replace the hubless blade 10. In addition, the second replacement part can also be applied to the holding of the hub provided on the hub blade (not shown). That is, the second replacement part can hold the hub of the hub blade and install and remove the hub blade relative to the blade fixing part 23 (specifically, the first flange 231). Therefore, the second replacement part can automatically replace the hub blade.

[0077] like Figure 1 As shown, the stocker unit 5 stores, for example, the hubless inserts 10 used in the processing unit 3 , the first flange 231 , and the like.

[0078] According to the first embodiment, the first replacement unit 52 and the second replacement unit (not shown) are provided on the rotatable rotary table 51. This makes it possible to make the processing apparatus 1 compact.

[0079] Furthermore, the hubless blade 10 can be manipulated by gripping the clamping portion 122. This allows for automated replacement of the hubless blade 10. Therefore, it is possible to expand the range of applicable workpieces.

[0080] Furthermore, the hub blade can be manipulated by holding the hub that is arranged on the hub blade not shown. Therefore, the hub blade can be automatically replaced. Thus, the hub blade 10 and the hub blade can be automatically replaced. Therefore, the scope of the applicable object workpiece can be further expanded.

[0081] In addition, owing to can promote the wearing and tearing of these blades when utilizing no hub blade 10 or hub blade processing difficult-to-cut material, so the replacement frequency of these blades is higher. In this case, also can improve productivity by automatically changing no hub blade 10 and hub blade.

[0082] In addition, by connecting the clamping portion 122 to the blade body 11, there is no need to touch the blade body 11 when manually replacing the hubless blade 10. This can suppress damage or abnormality of the blade body 11 caused by human error.

[0083] In addition, as described above, in order to manage the protrusion amount I of the hubless blade 10, it is necessary to replace the blade fixing portion 23 so that the outer diameter of the blade fixing portion 23 is changed according to the outer diameter of the worn hubless blade 10. Furthermore, with respect to the blade fixing portion 23, sometimes due to repeated installation and removal of the hubless blade 10, the hubless blade 10 contacts the end face of the blade fixing portion 23, causing scratches on the end face. In this case, although it is possible to repair the end face that contacts the hubless blade 10 to a certain extent, if the scratch is difficult to repair, it is necessary to replace the blade fixing portion 23. Furthermore, it is necessary to install and remove the blade fixing portion 23 when cleaning the spindle 221.

[0084] Therefore, the processing device 1 includes a first replacement unit 52 and a second replacement unit (not shown). The first replacement unit 52 can be automatically replaced by attaching or detaching the blade fixing unit 23 relative to the spindle 221. The second replacement unit can be automatically replaced by attaching or detaching the hubless blade 10 relative to the blade fixing unit 23. Thus, the protrusion amount I of the hubless blade 10 can be managed by automatically replacing the blade fixing unit 23.

[0085] In addition, if the scratch on the end surface of the blade fixing portion 23 is difficult to repair, the blade fixing portion 23 can be automatically replaced by the first replacement portion 52. Further, when cleaning the spindle 221, the blade fixing portion 23 can be automatically installed and removed by the first replacement portion 52.

[0086] [Second embodiment]

[0087] Next, a second embodiment of the present invention will be described. Figure 12 It is an exploded perspective view of the hubless insert according to this embodiment. Figure 13This is a cross-sectional view showing a state where a hubless blade is fixed by a blade fixing portion in the second embodiment. This embodiment differs from the first embodiment in the structure of the hubless blade and the blade fixing portion having a second flange 241. Detailed description will be given below.

[0088] like Figure 12 As shown, the hubless blade 100 includes a blade body 110 and a clamping portion (hub) 120. The blade body 110 is constructed in an annular shape. A through hole 111 is provided in the center of the blade body 110, and the through hole 111 is engaged with the shaft portion 233 of the first flange 231. The blade body 110, like the blade body 11 in the first embodiment, has abrasive grains dispersed in a binder phase composed of a resin material (resin).

[0089] The blade body 110 is engraved with blade information (barcode information). Examples of the blade information include the outer diameter, bonding phase, thickness, abrasive type, particle size, concentration, and serial number of the blade body 110. The engraving (printing) on ​​the blade body 110 disappears as it wears away. Therefore, the processing device 1 (see Figure 1 ) The blade information is associated with the clamping part information (described later) for recording.

[0090] The clamping portion 120 is detachably connected to the connecting portion 112 of the blade body 110 by, for example, bonding. The connecting portion 112 is located on one side of the blade body 110 on the side of the through hole 111. Figure 13 As shown, the clamping portion 120 is disposed on the side of the second flange 241. Methods for connecting the clamping portion 120 to the connecting portion 112 include, for example, a connection method using double-sided tape (including double-sided adhesive tape) or an adhesive. Other connection methods include connection methods using various diffusion bonding methods, including ultrasonic bonding, connection methods using welding methods such as spot welding or brazing, connection methods that combine the clamping portion 120 and the blade body 110, and various connection methods that allow the blade body 110 to be mounted on the clamping portion 120.

[0091] Double-sided tapes include double-sided adhesive tapes with adhesive properties on both sides, double-sided tapes with adhesive properties on one side and a cured adhesive on the other side, and double-sided tapes with a cured adhesive on both sides of a substrate.

[0092] Examples of the adhesive include fluid adhesive resins, sheet-shaped adhesive resins formed into a sheet, and materials that have no fluidity at room temperature but have fluidity under physical conditions such as temperature to function as an adhesive.

[0093] The clamping portion 120 is, for example, annular. A mounting hole 130 is provided in the center of the clamping portion 120, which engages with the shaft portion 233 of the first flange 231. The clamping portion 120 serves, for example, as a grip that can be manipulated by a second replacement unit (not shown). Therefore, by gripping the clamping portion 120 with the second replacement unit, the hubless blade 100 can be manipulated by the second replacement unit.

[0094] By gripping the clamping portion 120 and manipulating the hubless blade 100, the mounting hole 130 can be engaged with the shaft portion 233 of the first flange 231, thereby mounting the hubless blade 100 on the shaft portion 233. Alternatively, the clamping portion 120 can be gripped by the second replacement unit to remove the hubless blade 100 from the shaft portion 233. This allows for automated replacement of the hubless blade 100.

[0095] The second flange 241 includes a flange body 242 and a stopper 243. The flange body 242 includes an internal thread 244. The internal thread 244 of the second flange 241 is threadedly engaged with the external thread 236 of the shaft portion 233 of the first flange 231. Thus, the second flange 241 is fixed to the shaft portion 233 of the first flange 231. The stopper 243 protrudes from the outer periphery of the flange body 242 toward the hubless blade 100. The outer peripheries of the flange body 242 and the stopper 243 form the outer periphery 241a of the second flange 241. In other words, the stopper 243 of the second flange 241 is located at a position corresponding to the outer stopper 235 of the first flange 231. The outer diameter of the outer periphery 241a of the second flange 241 is, for example, the same as the outer diameter of the outer periphery 231a of the first flange 231.

[0096] When the second flange 241 is fixed to the shaft portion 233 of the first flange 231 , the blade body 110 of the hubless blade 100 is clamped by the outer stopper 235 of the first flange 231 and the stopper 243 of the second flange 241 .

[0097] In this state, the hubless blade 100 is fixed by the blade fixing portion 23. The blade fixing portion 23 is fixed to the main shaft 221. Therefore, the hubless blade 100 is fixed to the main shaft 221 via the blade fixing portion 23.

[0098] like Figure 13 As shown, when the hubless blade 100 is mounted on the shaft portion 233, the hubless blade 100 is fixed by the first flange 231 and the second flange 241 of the blade fixing portion 23. The blade fixing portion 23 is fixed to the main shaft 221. That is, the hubless blade 100 is fixed to the main shaft 221 via the blade fixing portion 23.

[0099] In addition, the clamping portion 120 is connected to the connecting portion 112 of the blade body 110. Figure 13 As shown, the outer diameter D of the clamping portion 120 is120 smaller than the outer diameter D of the blade fixing portion 23 23 The outer diameter D of the clamping portion 120 is 120 It is set to be smaller than the outer diameter D of the blade fixing portion 23 23 The reasons are as follows.

[0100] That is, the outer diameter D of the clamping portion 120 120 Greater than the outer diameter D of the blade fixing portion 23 23 In the case of the hubless insert 100, the protrusion I of the blade body 110 is limited by the clamping portion 120. When the hubless insert 100 is used to process a workpiece, the protrusion I affects the processing quality of the workpiece. Therefore, the outer diameter D of the clamping portion 120 is set to 120 It is set to be smaller than the outer diameter D of the blade fixing portion 23 23 Therefore, the protrusion amount I of the blade body 110 can be set as the distance between the outer periphery of the blade fixing portion 23 and the outer periphery of the blade body 110. 23 To manage (adjust) the protrusion amount I of the hubless blade 100 .

[0101] The clamping part information (barcode information) is engraved on the clamping part 120. Examples of the clamping part information include the type, outer diameter, shape, material, bonding type, and serial number of the hubless insert 100.

[0102] <Processing method>

[0103] Then, based on Figure 1 、 Figure 13 and Figure 14 A method for machining a workpiece using the hubless insert 100 will be described.

[0104] Figure 14 This is a flow chart showing the process of machining a workpiece using a hubless insert.

[0105] In this embodiment, an example of using only the hubless blade 100 to process a workpiece in the processing device 1 is described, but the processing device 1 can also mix the hubless blade 100 and other blades (for example, the hubless blade 10 or a well-known hub blade, etc.) to process the workpiece in the same way as the first embodiment.

[0106] First, an example of recycling the hubless insert 100 (specifically, the clamping portion 120 ) will be described based on a process including steps S1 to S10 .

[0107] like Figure 1 、 Figure 13 and Figure 14As shown, first, in the manufacturing process of the blade body 110, the blade body 110 of the hubless blade 100 is manufactured (S1). Next, in the manufacturing process of the hubless blade 100, the clamping part 120 is connected to the manufactured blade body 110 and the blade body 110 and the clamping part 120 are integrated to manufacture the hubless blade 100 (S2). The blade body 110 has abrasive particles dispersed in a binder phase of a resin material, for example. The binder phase of the resin material promotes the wear of the blade body 110 and is suitable for processing difficult-to-cut materials, for example. Therefore, the quality of processing using the hubless blade 100 can be ensured. In addition, the clamping part information is engraved on the clamping part 120. The blade information is engraved on the blade body 110.

[0108] In the process of putting in the hubless blade 100, the manufactured hubless blade 100 is put into the storage portion 5 of the processing device 1 for storage (S3). The engraving (printing) of the blade body 110 disappears due to the wear caused by the workpiece processing. Therefore, the processing device 1 associates the clamping part information with the blade information for recording. In the checking process of the hubless blade 100, when the hubless blade 100 is used to process the workpiece, the clamping part information and the blade information are checked to select the hubless blade 100 specified by the workpiece type (S4). In the automatic replacement process of the hubless blade 100, the selected hubless blade 100 is automatically transported for automatic replacement (S5).

[0109] During the workpiece machining process, the workpiece is machined using the automatically replaced hubless blade 100 (S6). The machining device 1 selects the assembly conditions (height-related or trimming) for the hubless blade 100 from the blade information to machine the workpiece. The workpiece machining conditions are determined by a recipe associated with the workpiece. The workpiece is machined using the hubless blade 100. The blade body 110 wears due to machining of the workpiece.

[0110] Due to the use of the hubless blade 100 to process a workpiece, the blade body 110 has reached a wear limit (S7). Since the blade body 110 has reached a wear limit, the hubless blade 100 is automatically replaced in the automatic replacement process (S8). At this time, the processing device 1 uses, for example, a detection sensor (not shown) to obtain information about the outer diameter of the worn blade body 110.

[0111] Here, when the hubless blade 100 (specifically, the clamping portion 120) is recycled, the processing device 1 refers to the type information from the clamping portion information and blade information of the used hubless blade 100 and stores it in a recycling tank (not shown). In addition, when processing a workpiece with a mixture of hubless blades 100 and hub blades in the processing device 1, the hub blade whose blade body has reached the limit of wear is discharged to a waste tank (not shown) and discarded. Therefore, the hubless blade 100 is prevented from mixing with the hub blade and is stored in the recycling tank.

[0112] In the recycling process, the hubless blade 100 is recovered from a recycling tank (not shown). The clamping portion 120 is peeled off from the recovered blade body 110. The clamping portion 120 peeled off from the blade body 110 is recovered (S9). In the recycling process, the recovered clamping portion 120 is connected to a new blade body 110 and recycled (S10). By connecting the clamping portion 120 to the new blade body 110 and replacing it, the protrusion amount I of the blade body 110 is ensured.

[0113] In order to recycle the clamping portion 120, the same clamping portion information is deployed again. However, since the clamping portion information is used in conjunction with the blade information, no problem will occur.

[0114] Next, an example of managing the protrusion amount of the hubless insert 100 and reusing the hubless insert 100 will be described based on the steps including S1 to S8 and S11 to S12.

[0115] Here, in normal workpiece processing, the smaller the protrusion of the hubless blade 100, the smaller the meandering, tilting, etc. of the blade body 110, thereby achieving excellent processing quality. In addition, depending on the thickness of the workpiece, the protrusion I required by the hubless blade 100 is also required. In this case, by automatically replacing the hubless blade 100, the hubless blade 100 can be reused (reused).

[0116] Specifically, when the hubless insert 100 is reused, each step from S1 to S8 in the process of recycling the hubless insert 100 is substantially the same.

[0117] That is, after the automatic replacement process (S5), during the workpiece processing process, the processing device 1 processes, for example, a thicker workpiece (S6). Since the hubless blade 100 is used to process the workpiece, the protrusion amount I reaches a limit due to wear of the blade body 110 (S7). If the protrusion amount I reaches the limit, in the automatic replacement process, the processing device 1 determines the wear limit based on the detected wear of the blade body 110 and automatically replaces the hubless blade 100 with a new hubless blade (S8).

[0118] In the storage process of the hubless blade 100, the used hubless blade 100 is temporarily stored in a reuse groove (not shown) along with the clamping portion information, blade information, and protrusion information of the blade body 110 (S11). In the reuse process, when processing a thin workpiece of similar type by the processing device 1, the hubless blade 100 with the smaller protrusion amount I is preferentially reused from among the hubless blades 100 temporarily stored in the reuse groove (S12).

[0119] In addition, sometimes there are multiple processing devices 1, and the workpiece is distributed to the multiple processing devices 1 for processing. In this case, when the used hubless blade 100 is temporarily stored in the reuse groove, the information of the protrusion amount I of the blade body 110 is shared with the server. The information of the protrusion amount I of the blade body 110 is printed on the blade body 110, for example. In the case where a thinner workpiece is processed by another processing device 1 among the multiple processing devices 1, the used hubless blade 100 is moved from the reuse groove to the other processing device 1. The processing device 1 can reuse the hubless blade 100 that can be processed and has a smaller protrusion amount I based on the information of the protrusion amount I of the blade body 110.

[0120] According to the hubless blade 100 of the second embodiment described above, the clamping portion 120 is connected to the blade body 110. Therefore, the hubless blade 100 can be manipulated by holding the clamping portion 120. This makes it possible to automate the replacement of the hubless blade 100. Therefore, it is possible to expand the applicable (machinable) workpieces.

[0121] In addition, the clamping portion 120 is detachably connected to the blade body 110. Therefore, when the protrusion amount I becomes small and affects the processing quality of the workpiece, the clamping portion 120 can be peeled off from the blade body 110 and recycled.

[0122] In addition, the outer diameter D of the clamping portion 120 is 120 It is set to be smaller than the outer diameter D of the blade fixing portion 23 23 Therefore, by changing the outer diameter D of the blade fixing portion 23 23 To manage the protrusion amount I of the hubless blade. In addition, by 120 For example, the hubless blade 100 may be smaller than the standard size of the hub in the hub blade, so that the hubless blade 100 can be used longer than the hub blade.

[0123] Furthermore, the protrusion amount I of the hubless blade 100 can be managed by replacing the blade fixing portion 23 with a different outer diameter in the processing device 1. In addition, the blade fixing portion 23 with a different outer diameter can be provided in each of a plurality of processing devices 1 to manage the protrusion amount I. In this way, the hubless blade 100 can be used for a long period of time while managing the protrusion amount I of the hubless blade 100.

[0124] Furthermore, since the clamping portion 120 can be detachably connected to the blade body 110, if the blade body 110 reaches its wear limit due to machining of a workpiece, resulting in a decrease in the protrusion amount I and thus affecting the machining quality of the workpiece, the clamping portion 120 can be peeled off from the blade body 110 and recycled. Alternatively, the hubless blade 100 that has reached its wear limit can be reused for an applicable workpiece.

[0125] Then, based on Figures 15 to 19 The third to sixth embodiments will be described. In the third to sixth embodiments, components identical or similar to those of the machining apparatus 1 and the hubless insert 100 are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0126] [Third embodiment]

[0127] based on Figure 15 The blade fixing portion in the third embodiment will be described.

[0128] Figure 15 1 is a cross-sectional view showing a state where a hubless blade is fixed by a blade fixing portion according to a third embodiment. Figure 15 As shown, the machining device 1 includes a blade fixing portion 23A in place of the blade fixing portion 23 of the first embodiment. The blade fixing portion 23A of this embodiment fixes the hubless blade 100. The blade fixing portion 23A of this embodiment includes a first flange 231A and a second flange 241. The first flange 231A includes a shaft portion 233, a flange body 234, an outer stopper 235, and an inner stopper 238.

[0129] The inner stopper 238 is provided in the flange body 234 at a position having a smaller diameter than the outer stopper 235. The front end 238a of the inner stopper 238 is flush with the front end 235a of the outer stopper 235 in a direction perpendicular to the axis of the shaft 233. Furthermore, the connection portion 112 of the blade body 110 contacts the front end 238a of the inner stopper 238 in the first flange 231A. The clamping portion 120 is connected to the side of the connection portion 112 opposite the inner stopper 238.

[0130] With the second flange 241 secured to the shaft 233 of the first flange 231A, the outer stopper 235 of the first flange 231A and the stopper 243 of the second flange 241 clamp the blade body 110 of the hubless blade 100. Furthermore, the connecting portion 112 of the blade body 110 contacts the front end 238a of the inner stopper 238 of the first flange 231A. The clamping portion 120 is connected to the side of the connecting portion 112 opposite the inner stopper 238.

[0131] In this state, the blade fixing portion 23A fixes the hubless blade 100. The blade fixing portion 23A is fixed to the main shaft 221. Therefore, the hubless blade 100 is fixed to the main shaft 221 via the blade fixing portion 23A.

[0132] In this embodiment, while the blade body 110 of the hubless blade 100 is being clamped by the outer stopper 235 of the first flange 231A and the stopper 243 of the second flange 241, the connecting portion 112 of the blade body 110 can be brought into contact with the front end 238a of the inner stopper 238. This allows the inner stopper 238 to support the connecting portion 112 of the blade body 110. This prevents damage to the blade body 110 at the portion 113 clamped between the first flange 231A and the second flange 241. In other words, damage to the blade body 110 while being clamped between the first flange 231A and the second flange 241 is prevented.

[0133] Furthermore, in the present embodiment, the first replacement portion 52 may be configured to automatically replace the second flange 241 .

[0134] [Fourth embodiment]

[0135] based on Figure 16 A blade fixing portion according to a fourth embodiment will be described.

[0136] Figure 16 It is a cross-sectional view showing a state where a hubless blade is fixed by a blade fixing portion according to a fourth embodiment.

[0137] like Figure 16 As shown, the machining device 1 includes a blade fixing portion 23B in place of the blade fixing portion 23A of the third embodiment. The blade fixing portion 23B includes a first flange 231A, a second flange 241A, and a nut 251. The second flange 241A has a through-hole 245 in place of the internal thread 244 of the second flange 241 of the third embodiment. The nut 251 engages with the external thread 236 of the shaft portion 233 of the first flange 231A.

[0138] Therefore, the second flange 241A is pressed onto the shaft portion 233 of the first flange 231A via the nut 251 and the blade body 110. Thus, the blade body 110 can be clamped by the first flange 231A and the second flange 241A of the blade fixing portion 23B. With the connecting portion 112 in contact with the front end 238a of the inner stopper 238, the hubless blade 100 is fixed by the blade fixing portion 23B.

[0139] By providing the machining apparatus 1 with the blade fixing portion 23B of the fourth embodiment instead of the blade fixing portions 23 and 23A, it is possible to expand applicable workpieces similarly to the second and third embodiments.

[0140] [Fifth embodiment]

[0141] Then, based on Figures 17 to 19 A hubless blade and a second replacement portion according to a fifth embodiment will be described.

[0142] Figure 17 It is a cross-sectional view showing a state where the hubless insert according to the fifth embodiment is fixed by an insert fixing portion. Figure 18 It is a cross-sectional view showing a hubless blade.

[0143] like Figure 17 and Figure 18 As shown, the hubless blade 100A includes a clamping portion (hub) 120A, as opposed to the clamping portion 120 of the second embodiment. That is, the hubless blade 100A includes a blade body 110 and a clamping portion 120A. The clamping portion 120A is, for example, similar to the clamping portion 120 of the second embodiment, detachably connected to the connecting portion 112 on one side of the blade body 110. However, the difference between the clamping portion 120A and the clamping portion 120 disposed on the second flange 241 side is that the clamping portion 120A is disposed on the first flange 231 side.

[0144] The clamping portion 120A is ferromagnetic and is, for example, made of magnetic stainless steel in an annular shape. A mounting hole 121A is provided in the center of the clamping portion 120A, and the mounting hole 121A engages with the shaft portion 233 of the first flange 231. The diameter of the mounting hole 121A is smaller than the diameter of the through-hole 111 of the blade body 110. The clamping portion 120A serves as a gripping portion that can be manipulated by, for example, the second replacement portion 90 described later. Therefore, by gripping the clamping portion 120A by the second replacement portion 90, the hubless blade 100A can be manipulated by the second replacement portion 90.

[0145] By gripping the clamping portion 120A and manipulating the hubless blade 100A, the mounting hole 121A can be engaged with the shaft portion 233 of the first flange 231, thereby mounting the hubless blade 100A on the shaft portion 233. Alternatively, the clamping portion 120A can be gripped by the second replacement unit 90 to remove the hubless blade 100A from the shaft portion 233. This allows for automated replacement of the hubless blade 100A.

[0146] Figure 19 It is a cross-sectional view illustrating an example of attaching and detaching the hubless blade by the second replacement portion according to the fifth embodiment.

[0147] like Figure 19As shown, the second replacement part 90 includes an adsorption part 91 and a relaxation part 92. The adsorption part 91 is provided in the second replacement part 90. The adsorption part 91 is constructed in a ring shape by a magnet. A through hole 94 is provided in the central part of the adsorption part 91, and the through hole 94 is engaged with the shaft part 233 of the first flange 231. The inner diameter of the through hole 94 of the adsorption part 91 is substantially the same as the inner diameter of the through hole 111 of the blade body 110. In the third embodiment, an example in which the adsorption part 91 is constructed by a magnet is described, but the adsorption part 91 may also be constructed by an electromagnet instead of a magnet.

[0148] The buffer portion 92 is annularly constructed from a non-magnetic material such as resin. A through-hole 95 is provided in the center of the buffer portion 92, which engages with the shaft portion 233 of the first flange 231. The inner diameter of the through-hole 95 of the buffer portion 92 is approximately the same as the inner diameter of the through-hole 111 of the blade body 110. The buffer portion 92 contacts the connecting portion 112 of the blade body 110. The connecting portion 112 is located at a position opposite the front end 238a of the inner stopper 238 in the axial direction of the shaft portion 233. In other words, the buffer portion 92 is located at a position opposite the front end 238a of the inner stopper 238.

[0149] The second replacement portion 90 is provided with a suction portion 91 , and a relief portion 92 is detachably provided on a surface (outer surface) of the suction portion 91 .

[0150] When the hubless blade 100A is fixed to the blade fixing portion 23A by the second replacement portion 90, the buffer portion 92 of the second replacement portion 90 is brought into contact with the connecting portion 112 of the blade body 110. By bringing the buffer portion 92 into contact with the connecting portion 112, the clamping portion 120A is adsorbed by the adsorption portion 91. The clamping portion 120A is adsorbed by the magnetic force of the adsorption portion 91, thereby being gripped by the second replacement portion 90. In other words, the hubless blade 100A is gripped via the clamping portion 120A using the magnetic force of the adsorption portion 91 from the surface of the blade body 110 on the opposite side to the clamping portion 120A. The gripped clamping portion 120A is manipulated by the second replacement portion 90. The manipulated hubless blade 100A is arranged on the shaft portion 233 of the first flange 231A. Specifically, the through hole 111 of the blade body 110 and the mounting hole 121A of the clamping portion 120A are fitted into the shaft portion 233 , and the through hole 94 of the adsorption portion 91 and the through hole 95 of the relaxation portion 92 are fitted into the shaft portion 233 .

[0151] Here, the diameter of the mounting hole 121A of the clamping portion 120A is smaller than the diameters of the through-hole 111 of the blade body 110, the through-hole 94 of the adsorption portion 91, and the through-hole 95 of the relaxation portion 92. Therefore, when the hubless blade 100A is secured to the blade securing portion 23A, the through-holes 111, 94, and 95 (particularly the through-hole 111 of the blade body 110) are prevented from contacting the shaft portion 233. This prevents damage to the blade body 110 caused by contact between the through-hole 111 of the blade body 110 and the shaft portion 233.

[0152] When the hubless blade 100A is positioned on the shaft 233 of the first flange 231A, the blade body 110 contacts the front end 235a of the outer stopper 235. Furthermore, the connecting portion 112 of the blade body 110 contacts the front end 238a of the inner stopper 238. The relief portion 92 contacts the connecting portion 112. Therefore, the blade body 110 can be positioned so that it contacts the front ends 235a and 238a. This prevents the hubless blade 100A from moving inward relative to the front end 235a of the outer stopper 235. This prevents the blade body 110 from bending or being damaged.

[0153] After the hubless insert 100A is placed on the shaft 233 , the adsorption portion 91 is separated from the relief portion 92 as indicated by the arrow. After the adsorption portion 91 is separated from the relief portion 92 , the relief portion 92 is separated from the connection portion 112 of the insert body 110 .

[0154] like Figure 17 and Figure 19 As shown, after the relaxation portion 92 is separated from the connection portion 112, the second flange 241 is fixed to the shaft portion 233 of the first flange 231A. Specifically, the internal threads 244 of the second flange 241 are threadedly engaged with the external threads 236 of the shaft portion 233 of the first flange 231A. By threading the internal threads 244 with the external threads 236 of the shaft portion 233, the second flange 241 is fixed to the shaft portion 233 of the first flange 231A. Thus, the hubless insert 100A is clamped between the second flange 241 and the first flange 231A, and the hubless insert 100A is fixed by the insert fixing portion 23.

[0155] Next, when removing the hubless blade 100A from the blade fixing portion 23 using the second replacement unit 90, the second flange 241 is removed from the shaft portion 233 of the first flange 231A. After removing the second flange 241 from the shaft portion 233, the adsorption portion 91 and the relaxation portion 92 of the second replacement unit 90 are brought into contact with the connecting portion 112 of the blade body 110. By bringing the relaxation portion 92 into contact with the connecting portion 112, the adsorption portion 91 adsorbs and grips the clamping portion 120A. After gripping the clamping portion 120A, the hubless blade 100A is removed from the shaft portion 233 using the second replacement unit 90. In this manner, the hubless blade 100A can be automatically replaced using the second replacement unit 90.

[0156] According to the hubless blade 100A and the second replacement part 90 of the third embodiment described above, Figure 17 and Figure 19 As shown, similarly to the second embodiment, the applicable workpieces can be expanded.

[0157] Here, the hubless blade 100A is fixed to the blade fixing portion 23 by fitting the through hole 111 of the blade body 110 and the mounting hole 121A of the clamping portion 120A with the shaft portion 233. Therefore, when the hubless blade 100A is fixed to the blade fixing portion 23A, it is conceivable that the blade body 110 may be damaged due to contact between the through hole 111 and the shaft portion 233.

[0158] Therefore, the diameter of the mounting hole 121A of the clamping portion 120A is set to be smaller than the diameter of the through hole 111 of the blade body 110. Therefore, when the hubless blade 100A is fixed to the blade fixing portion 23A, the through hole 111 is prevented from contacting the shaft portion 233. This prevents damage to the blade body 110 caused by contact between the through hole 111 and the shaft portion 233.

[0159] [Sixth embodiment]

[0160] Then, based on Figure 20 A sixth embodiment will be described.

[0161] Figure 20 1 shows the structure of the sixth embodiment, and is a cross-sectional view showing a state in which the hubless blade of the fifth embodiment is fixed by the blade fixing portion of the fourth embodiment.

[0162] like Figure 20 As shown, in the sixth embodiment, the hubless blade 100A can be automatically replaced with the blade fixing portion 23B of the fourth embodiment. According to the sixth embodiment, similarly to the second embodiment, it is possible to expand the applicable workpieces.

[0163] In addition, the technical scope of the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the spirit of the present invention.

[0164] For example, although the stocker portion 5 in the first embodiment stores the hubless blades 10 and the first flange 231 , it may store the hubless blades 100 , the second flange 241 , the hub blades, and the like.

[0165] Furthermore, the structural elements in this embodiment may be appropriately replaced with well-known structural elements without departing from the scope of the present invention.
