Thin plate processing device and method for manufacturing thin plate member

The present invention relates to a thin plate processing apparatus and a method of manufacturing a thin plate member.

In the thin plate processing apparatus, for example, a grinding device for performing end surface grinding of a workpiece having a substantially square thin plate shape, which is used for performing end face grinding of a carrier end plate glass such as a mobile phone, is known. This end-mounted monitor uses a thin glass plate. Such a thin plate glass is generally cut out from a large-shaped glass plate into a substantially workpiece shape, and the end surface of the cut glass plate is accurately ground by a grinding device to form a predetermined shape. In particular, in the case of this grinding, the chamfering process is simultaneously performed to prevent the end face of the thin glass from being defective.

In recent years, for example, in the carrying end of a mobile phone or the like, the display of the display screen is increased by all of the ones carrying the end or most of the end. In such a case, in particular, the screen is often multi-touched, and the end of the carrying end covered by the thin glass is increased.

The sheet-shaped object processing apparatus according to the present invention is characterized in that the sheet-shaped workpiece is processed, and the storage unit is provided with a first rail and travels along the first rail to carry and carry out the workpiece. a traveling body; the supply unit is disposed on one side of the vicinity of the start end of the first rail, and supplies an unprocessed workpiece to the transport carry-out unit; and the discharge unit is disposed near the beginning of the first track On the other side, the processed workpiece is discharged from the transport carry-out unit; and the plurality of processing units are disposed along the first rail to process the workpiece; the plurality of processing units each have : the processing stage holds the workpiece to be processed; and the second rail is in a direction intersecting the first rail, and the processing stage is transferred from the processing position to the conveyance and discharge unit and the workpiece is transferred. The transporting and unloading unit further includes a rotating body that is attached to the traveling body to follow the first rail. The axis of the arrangement direction is centered; and the workpiece holding portion is provided on the rotating body, and is disposed at least selectively facing the processing stage at the transfer position by the rotation of the rotating body Two places.

In the thin plate processing apparatus, the unprocessed workpiece is supplied to the workpiece holding unit by the supply unit, and then the traveling body is moved until the processing position of the processing stage is held, and the workpiece is held by the workpiece. The unprocessed workpiece of the part can be conveyed to the processing stage by being transferred to the processing stage. Further, the workpiece holding unit is a processed object held by the processing stage that receives the delivery position, and is processed. Thereafter, the traveling body is moved until the discharge position of the discharge unit, and the processed workpiece held by the workpiece holding unit is discharged by the discharge unit, whereby the workpiece to be processed by the processing stage can be discharged. In particular, since the workpiece holding portion is provided in at least two places, the above-described conveyance program and the discharge program can be substantially continuously performed. In other words, for example, one of the workpiece holding portions holds the unprocessed workpiece, and the traveling body moves to the processing position of the processing stage in a state where the other workpiece holding portion does not hold the workpiece. The workpiece holding unit receives the processed workpiece from the processing stage, and then rotates the rotating body so that the one of the workpiece holding portions faces the workpiece. The unprocessed workpiece held by the workpiece holding unit can be delivered to the processing stage by the vacant processing stage that is delivered.

Further, since the plurality of processing units are disposed along the first rail, the processing operation such as the grinding operation can be performed by another processing unit during the operation of carrying and unloading the one processing unit as described above, and the productivity can be improved.

Further, since the processing stage is moved from the delivery position to the processing position by the second rail, it is possible to distinguish between the field in which the workpiece is transferred and the field in which the workpiece is processed.

Further, since the traveling body travels along the first track and the processing stage is a simple structure that travels along the second track, the cost can be suppressed and the failure is less likely to occur than in the case of using a conventional handling component. And easy to repair.

In the thin plate processing apparatus, the rotating body is preferably attached to the traveling body on the side of the processing stage that can be approached/away from the transfer position. In other words, the processing stage and the workpiece holding unit need to be approached/deviated in order to transfer the workpiece. However, for example, if the processing stage is moved up and down, the structure may be complicated. Therefore, the rotating body is installed as described above. The structure is simple to approach/deviate from the traveling body, and it is possible to prevent the cost of the device from being high, and it is not easy to malfunction, and the maintenance is easy.

Further, when the camera is provided as described above, the camera is attached to the traveling body on the opposite side of the processing stage at the transfer position of the rotating body, and the rotating body is formed to be visually confirmed from the camera at a predetermined rotation angle. The field of visual inspection of the processing stage at the transfer position is preferred. Thereby, after the unprocessed workpiece is transferred to the processing stage, the traveling body does not move, and the workpiece held by the processing stage can be photographed by the camera. In particular, since the camera is located on the opposite side of the processing stage at the delivery position of the rotating body, the distance between the camera and the workpiece can be lengthened, whereby the entire workpiece can be imaged with good focus. Further, since the field of the visual inspection is formed in the rotating body, the unprocessed workpiece is transferred to the processing stage, and after the rotating body is rotated, the workpiece on the processing stage can be visually confirmed from the camera. The workpiece is actually photographed.

Further, in the thin plate processing apparatus, the rotating body has a pair of facing facing walls, and the facing objects are preferably provided with the workpiece holding portion facing outward. Thereby, when one of the workpiece holding portions is directed to the supply unit side position, the other workpiece holding portion is a position that faces the supply unit and the discharge unit located at the position where the first rail is held. Therefore, it is easy to simultaneously perform the supply of the unprocessed workpiece by the supply unit and the discharge of the workpiece by the processing of the discharge unit, thereby shortening the time for carrying and unloading the workpiece, and Improve productivity.

Further, for the thin plate processing device, the processing table is provided with There is a plurality of holding means for holding the workpiece, and at least two of the workpiece holding portions are preferably provided with a plurality of workpiece holding means corresponding to the holding means.

In this way, the plurality of workpieces can be transported and carried out by only one transport and unloading operation, and since the plurality of workpieces can be processed by the processing stage, productivity can be further improved.

Further, in the thin plate processing apparatus, all of the plurality of processing units are preferably arranged such that the processing position is on the same side with respect to the first track. Therefore, there is an advantage that the first rail can be disposed on the side surface of the apparatus at the processing position side where the processing unit is not provided, so that the repair of the transport unit, the inspection point, and the like can be easily performed.

Further, the thin plate processing apparatus further includes a control means for controlling the operation of the traveling body and the rotating body, and the control means controls the following steps: at least two of the workpiece holding portions One of the steps of supplying the unprocessed workpiece through the supply unit, and the step of moving the traveling body holding the unprocessed workpiece to the delivery position of the processing stage in the workpiece holding unit; The processed object to be processed by the processing stage is charged by the other of the at least two workpiece holding portions; the rotating body is rotated, and the processed workpiece is transferred and processed. The mounting table transfers the unprocessed addition held by the workpiece holding portion of the one of the above-mentioned workpieces a step of holding a workpiece of the workpiece to be processed in the workpiece holding portion, a step of walking until the discharge position of the discharge unit, and holding the other workpiece holding portion The step of discharging the processed workpiece through the discharge unit is preferred. By the control of such a control means, the program to be transported and the program to be discharged can be surely and substantially continuously performed, and the productivity can be surely improved.

As described above, the present invention has a configuration in which the carry-out unit and the plurality of processing units are movably provided along the first rail and the second rail. Therefore, the simple structure is the same as the case of using the conventional transport unit. The ratio can be suppressed, the cost is high, and it is not easy to malfunction, and the maintenance is easy.

The processing tool 104 of the above-described grinding assembly 100 is detachably provided with a processing tool 130 for processing the mounting table 103. The end surface of the workpiece W (thin glass) is subjected to grinding or the like. This processing tool 130 is ground for the end surface of the workpiece W to be contacted by, for example, rotation. Further, the processing tool 130 may be a hole puncher that is grounded against the workpiece W. Further, on the processing stage 103, a plurality of types of processing tools 130 are placed, and the processing tool 130 for the purpose is attached to the processing machine 104. Specifically, for example, by using a processing tool composed of a large-diameter cylindrical vermiculite, the machining tool can be stably ground during the grinding process, so that the machining accuracy can be improved, and since the machining tool has a large diameter, it is also possible Extending the life of the tool allows for a large and continuous grinding of the workpiece W. On the other hand, by inserting a machining tool composed of a small-diameter cylindrical vermiculite into the hole portion of the workpiece W, the inner shape grinding and chamfering of the hole portion can be performed.

Further, the processing machine 104 has a processing shaft (not shown) that detachably mounts the processing tool 130 at the tip end. The machining shaft includes an electric motor (not shown) that generates a rotational driving force during machining, and a disk that mounts the machining tool on a rotating shaft of the electric motor.

The processing spindle (processing machine 104) is provided to be movable along the arrangement direction of the first rail 11. Therefore, the machining tool is moved so that the workpiece W on the processing stage 103 can relatively move in the horizontal direction (front, rear, left, and right directions) by moving the processing stage 103 and the processing rotating shaft. Further, the processing shaft is also set to be movable in the vertical direction.

Further, the grinding unit 100 further preferably includes a grinding liquid spraying means (not shown) for spraying the grinding liquid toward the processing tool 130 attached to the processing shaft. Moreover, the grinding assembly 100 is provided with a corrugated cover (illustrated province Slightly), etc., when the grinding is performed, the flying grinding fluid does not invade the transfer position or the like. Further, although not shown in detail, it is preferable that the workpiece W is provided with a recovery tray (not shown) for collecting the grinding liquid to be sprayed.

The grinding device M has control means for controlling various actions. Here, the control means may be constituted by, for example, an electronic control unit.

In the control means, the unprocessed workpiece W is supplied to the processing stage 103 by the conveyance/disassembly unit 10, and the processed workpiece W is carried out from the processing stage 103. However, the conveyance method will be described below.

First, when the grinding operation is started, the transporting and unloading unit 10 is located on the starting end side of the first rail 11. Further, the supply unit 60 picks up the unprocessed workpiece W from the workpiece cassette 61, and the supply unit 60 delivers the unprocessed workpiece W to the workpiece holding unit 27 on one side of the conveyance/outlet unit 10. At the time of the transfer, the suction and stop of the workpiece holding unit 27 of the conveyance unit 10 and the suction unit of the supply unit 60 are controlled. Such suction and stop control is also performed at the time of delivery of the workpiece W to be described later, and a detailed description thereof will be omitted below.

The conveyance/unloading unit 10 that collects the unprocessed workpiece W is moved until the delivery position of one of the plurality of grinding assemblies 100. Further, at this time, the processing stage 103 of the grinding unit 100 also moves until the delivery position.

Further, the rotating body 25 is rotated by 90°, and the workpiece holding portion 27 holding the workpiece W is directed downward, so that the workpiece W and the processing placing table 103 face each other. Further, the rotating body 25 is lowered to transfer the workpiece W to the processing stage 103.

Thereafter, the rotating body 25 is rotated (reversed) by -90°, and the workpiece W on the processing stage 103 is photographed by the camera 23.

After the photographing, the processing stage 103 is moved toward the processing position, the grinding operation is started, and the transport carrying-out unit 10 is moved toward the starting point side of the first rail 11.

The conveyance operation described above is performed in each of the grinding assemblies 100, and the workpiece W is supplied to each of the grinding assemblies 100.

Further, when the grinding operation is completed in the grinding unit 100, the processing stage 103 is moved until the delivery position. In the state in which the unprocessed workpiece W is held by the workpiece holding portion 27 on one side, the unloading unit 10 is moved to the delivery position. At this time, in the workpiece holding portion 27 on the other side, the workpiece W is not in an empty state.

Thereafter, the rotating body 25 is rotated (reversed) by -90°, and the workpiece holding portion 27 on the other side of the workpiece W that is not held by the workpiece W faces downward, and the workpiece W and the processing stage 103 face each other. Further, the rotating body 25 is lowered to collect the processed workpiece W from the processing stage 103.

Further, the rotating body 25 is rotated by 180°, and the workpiece holding portion 27 holding the workpiece W is directed downward, so that the workpiece W and the processing stage 103 face each other. Further, the rotating body 25 is lowered to transfer the workpiece W to the processing stage 103.

Thereafter, the rotating body 25 is rotated (reversed) by -90°, and the workpiece W on the processing stage 103 is photographed by the camera 23.

After the photographing, the processing stage 103 is moved toward the processing position, the grinding operation is started, and the conveyance and delivery unit 10 is moved toward the start point of the first rail 11. Side movement.

After moving toward the start point side of the first rail 11, the discharge unit 70 receives the processed workpiece W from the workpiece holding portion 27 on the other side of the transport/outlet unit 10, and finishes the processing of the workpiece W toward the processing. The workpiece cassette 71 of the workpiece W is housed, and the supply unit 60 receives the unprocessed workpiece W from the workpiece cassette 61 of the unprocessed workpiece W, and the supply unit 60 is the one that moves the unprocessed workpiece W toward the transport and carry-out unit 10. The workpiece holding portion 27 on the side is delivered.

In this manner, the conveyance/unloading unit 10 that collects the unprocessed workpiece W is moved until the delivery position of the other grinding unit 100 until the end of the grinding operation, and the above-described conveyance and discharge operation is repeated.

Further, although the control means calculates the grinding path of the workpiece W based on the data photographed by the camera 23, the control method at the time of this calculation is explained from Fig. 14 to Fig. 15.

As shown in the flowchart of Fig. 14, after starting, first, the model data (outer shape, hole portion, and the like) of the workpiece W is input (mounted) to the electronic control unit (input process) by S1. In this manual work, for example, the design data (CAD data) of the workpiece Wo that has been correctly processed is taken into another software, converted into a grinding data such as a grinding path, and then input (installed) to the electronic control unit.

After the completion of such an input operation, the actual workpiece Wi (hereinafter referred to as the actual workpiece W) is placed (loaded) on the processing stage 103 by S2, and the workpiece Wi is held by the adsorption stage 108 (holding process).

Thereafter, by S3, the real workpiece Wi and the reference are made by the camera 23. The images of the pins 116, 116 are taken in (photographing process). Specifically, the workpiece Wi of the processing stage 103 and the reference pins 116 and 116 are imaged by the camera 23. By recording the processing stage 103 from a position away from above, it is possible to reduce the deformation of the image data of the workpiece Wi and the reference pins 116 and 116 taken in as much as possible.

An example of the image data thus taken in is the figure shown in Fig. 15 (a). The workpiece Wi and the two reference pins 116 and 116 are taken in as image data, and each position data is calculated.

Further, from S4, the machine origin C (machine origin calculation process) of the machining stage 103 is calculated from the positions of the reference pins 116 and 116. Here, the machine origin C is a reference for mechanical coordinates for grinding, and by correcting the machine origin C, it is possible to perform correct grinding.

The machine origin C is determined by the midpoint of the line L connecting the two reference pins 116 and 116 as shown in Fig. 15(b). Further, in another example, as shown by the broken line, the two reference pins 116' and 116' are further added, and the line N connecting the two additional reference pins 116' and 116' and the two reference pins 116 are defined. The intersection of the line L connected by 116 may be used as the machine origin C.

In S5, the gravity center position P of the outer shape Wa of the real workpiece Wi and the gravity center position Q of the hole portion Wb are calculated from the data of the actual workpiece Wi taken in (the center of gravity position calculation process). Here, the position of the center of gravity is the position of the center of gravity of the figure, and is determined by the shape of the outer shape of the workpiece W and the shape of the hole portion. The black circles P and Q shown in Fig. 15(b) are the center of gravity of the outer shape Wa of the real workpiece W, and the hole portion Wb and the center of gravity.

Thereafter, in S6, the position of the center of gravity of the real workpiece Wi (the center of gravity P of the outer shape and the position of the center of gravity Q of the hole) and the position of the center of gravity of the model Wm (the center of gravity Pm of the outer shape and the position of the center of gravity Qm of the hole) are matched. By matching the center-of-gravity positions P and Q of the real workpiece W and the centroid positions Pm and Qm of the model Wm, the real workpiece Wi and the model Wm and the difference (difference in positional data) can be made clear. The state shown in Fig. 15(c) is a state in which the center of gravity position P, Q, Pm, and Qm of the real workpiece Wi and the model Wm (point lock line) are matched. By thus matching the center-of-gravity positions P, Q, Pm, and Qm, the difference between the workpiece Wi and the model Wm can be clarified.

In S7, the machine origin C of the machining stage 103 and the center of gravity P of the real workpiece Wi are compared, and the amount of deviation of the center of gravity C of the machine origin C and the real workpiece Wi is calculated (the amount of deviation X in the lateral direction, and the direction in the longitudinal direction) Deviation amount Y, deviation amount θ) of the rotation direction (deviation amount calculation process). Further, the workpiece Wi and the model Wm are compared, and the amount of cut ΔW is also calculated by the difference in the shape. In this case, the amount of grinding of the actual workpiece Wi can be clarified.

Figure 15 (d) shows the amount of deviation and the amount of cutting. The amount of deviation of the center of gravity P of the real workpiece Wi from the machine origin C of the processing stage 103 is, for example, shifted from the left side by X, the upper side by the Y, and further inclined by θ toward the right side.

In addition, the amount of shaving ΔW1 in the width direction is calculated by subtracting the width dimension T1 of the model from the width dimension r1 of the real workpiece Wi and dividing it by two, and the amount of shaving ΔW2 in the longitudinal direction is It is calculated by subtracting the length dimension T2 of the model from the length dimension r2 of the real workpiece Wi and dividing by 2.

In this case, the width direction and length direction and the amount of cutting are obtained. After ΔW1 and ΔW2, the large value is determined as the final cutting amount ΔW. The reason for this determination is that when the grinding process is performed, since the workpiece W is cut by a constant amount of cutting from the trajectory similar to the shape of the model, it is possible to surely generate the cutting by determining a large value. It can be ground closer to the shape of the model.

Further, in S8, the grinding path of the workpiece Wi (the grinding path calculation process) is calculated corresponding to the amount of deviation of X, Y, and θ and the amount of cutting ΔW. This grinding path changes depending on the shape of the actual workpiece Wi and the variation of the mounting position of the real workpiece Wi, and is different for each workpiece W.

Thereafter, the real workpiece Wi is ground (slicing process) from the calculated grinding path by S9. This grinding operation is performed by moving the grinding shaft 131 and the processing stage 103 separately. In the grinding operation of the workpiece W, the above-described large-diameter processing tool 130A and the small-diameter processing tool 130B are used in accordance with the grinding portion.

Finally, in S10, the real workpiece Wi is taken out from the processing stage 103 as described above (moving out process).

Then, when it is judged by S11 whether or not the job is finished, and the job is continued (in the case of NO determination), the next workpiece W is again moved to the above S2. On the other hand, when the work is finished (in the case of YES judgment: when the power is turned off (OFF)), it is directly moved to the end.

As described above, by grinding the end surface of the workpiece W together with the control of the above-described control means, the thin plate-shaped member whose end surface is ground can be manufactured.

In the grinding device M, since the workpiece holding portion 27 is provided at Since there are two places, the discharge program and the transfer program can be continuously performed by one transport/outlet unit 10, and the production efficiency can be improved.

In particular, since the plurality of grinding assemblies 100 are provided, the grinding operation can be performed by the other grinding unit 100 during the operation of carrying and unloading as described above in one of the grinding units 100, and the productivity can be further improved.

Further, the supply unit 60 and the discharge unit 70 are disposed at positions to hold the first rails 11, and the workpiece holding portions 27 are respectively disposed on the facing walls of the rotating body 25, thereby being simultaneously performed as follows: The supply of the unprocessed workpiece W by the supply unit 60 and the discharge of the workpiece W by the processing by the discharge unit 70 can shorten the conveyance time of the workpiece W, and the productivity can be further improved.

Further, in the grinding apparatus M, since the processing stage 103 has the plurality of adsorption stages 108 that can hold the workpieces W individually, it is possible to perform the grinding of the plurality of workpieces W by one processing operation. In the workpiece holding unit 27, the plurality of workpiece holding members 29 are provided in the suction table 108 corresponding to the processing stage 103. Therefore, the plurality of workpieces can be transported by only one transport operation. W transport and carry out. Therefore, productivity improvement can be further achieved. In particular, for example, when processing is performed by a plurality of types of processing tools in one processing operation, after the processing tool is mounted, the same processing can be performed on the plurality of workpieces W by the one processing tool, and thereafter The above-described one processing tool is detached and other processing tools are mounted, whereby the same processing processing by other processing tools can be performed on the plurality of workpieces W described above. That is, because only one processing tool is loaded and unloaded Since the processing of a plurality of workpieces can be performed, the time required for loading and unloading the processing tool can be shortened, and work efficiency can be improved.

Further, since the processing stage 103 is moved from the delivery position to the processing position by the second rail 101, it is possible to distinguish the field in which the workpiece W is transferred and the field of processing, and the processing position is wet due to the grinding fluid. However, the transfer position can be distinguished from this wet state. In addition, it is possible to distinguish the dryness of each workpiece holding portion 27 by holding only the dry unprocessed workpiece W in one of the two workpiece holding portions 27 and keeping only the wet-processed workpiece W in the other. Wet state.

Further, since the traveling body 13 travels along the first rail 11 and the processing stage 103 is a simple structure that travels along the second rail 101, the cost can be suppressed as compared with the case of using a conventional scalar robot arm. High, and not easy to cause malfunction, and easy to repair.

In addition, since the rotating body 25 is moved up and down toward the traveling body 13, and is close to and away from the processing stage 103 side, the structure is relatively simple, and it is possible to prevent the cost of the apparatus from being high, and it is difficult to be trouble-free, and maintenance is easy.

In the grinding device M, all of the plurality of grinding assemblies 100 are disposed on the same side with respect to the first rail 11, so that the first rail can be placed on the processing position side where the grinding assembly 100 is not provided. The 11 is disposed on the side of the device and has the advantage that the handling and inspection of the handling components can be easily performed.

Since the supply unit 60 and the discharge unit 70 are provided near the beginning of the first rail 11, the supply portion and the discharge of the workpiece W can be disposed on one side surface (the side surface on the start side of the first rail 11) of the grinding device M. section. Therefore, the operator of one person can input/take in the workpiece cassettes 61 and 71 from one side.

Further, the camera 23 is attached to the traveling body 13, and the workpiece W on the processing stage 103 is photographed, and the grinding operation can be performed by the correct grinding path in accordance with the photographic data.

In particular, the data of the model of the workpiece W is mounted in advance, and the photographic data of the reference pin 116 taken in by the camera 23 is calculated from the machine origin of the processing stage 103, and the photographic data of the workpiece W taken in from the camera 23 is calculated. The position of the center of gravity of the workpiece W is obtained, and the machine origin of the machining stage 103 and the center of gravity P of the workpiece W are compared, and the amount of deviation of the workpiece W is calculated, and the grinding path is calculated corresponding to the amount of deviation, so that the workpiece W can be accurately performed. Grinding. In particular, even if the "reference mark (print)" or the like is not formed in the workpiece W itself, the "machine origin" can be obtained by the reference pin provided on the processing stage 103, because the amount of deviation of the workpiece W can be grasped. Therefore, it is possible to perform the grinding process reliably even in the thin glass (workpiece W) used for the display screen on the end of the mobile phone.

In addition, it is conceivable to provide a plurality of cameras 23, and each of the processing stages 103 is provided with a camera 23. However, by attaching the camera 23 to the traveling body 13 as described above, it is not necessary to provide a plurality of cameras 23. The cost of the suppression device is high.

Further, since the camera 23 is positioned above the traveling body 13, the distance between the camera 23 and the object to be photographed, that is, the workpiece W can be lengthened, whereby the entire workpiece W can be photographed in a good focus.

And because it is possible to select and set a plurality of types of suction on the processing stage 103 Since the table 108 is attached, the size of the workpiece W is corresponding to the object to be ground, and the appropriate suction stage can be selected to perform the grinding operation. Further, when the first or third holding base 107 is placed and fixed, the plurality of adsorption stages 108 may be provided on the processing stage 103. Thereby, it is possible to select a more suitable adsorption stage 108 for the grinding operation without changing the holding base 107.

Further, since the plurality of reference pins 116 are provided, and the plurality of reference pins 116 are disposed outside the outer shape of each workpiece W held by the adsorption stage 108, the reference pin 116 is positioned closer to the workpiece W. The "machine origin" becomes the position of the center of gravity close to the workpiece W, and the error in the calculation of the deviation amount can be reduced. Further, since the reference pin 116 is located at both sides of the workpiece W, the point formed on the line connecting the reference pins 116 on both sides of the workpiece W can be used as the "machine origin", thereby being close to each other. The position of the center of gravity of the workpiece W is taken as the machine origin. Further, since at least two pairs of reference pins 116 that face the workpiece W are disposed, the mechanical origin can be made by using the intersection of the lines connecting the pair of reference pins 116 as the "mechanical origin". And the position of the center of gravity of the workpiece W is closer. Therefore, the amount of deviation of the workpiece W can be calculated more correctly.

Further, since the reference pin 116 that is erected on the base pallet 109 is located outside the outer shape of the workpiece W held by the suction stage 108, the reference pin 116 is not hidden by the workpiece W, and therefore, even if the setting is changed, It is not necessary to replace the reference pin 116 or the like in any of the first, second, and third adsorption stages 108, and the photographing operation can be surely performed. because Thereby, the structure of the processing stage 103 can be made simple.

Further, the present invention is not limited to the above-described embodiments, and can be appropriately modified and modified within the scope of the invention.

In the grinding apparatus M of the above-described embodiment, the workpiece W as the workpiece is a thin plate glass for a mobile phone, but for example, a thin plate glass for an acoustic device may be carried, and a thin plate glass for carrying a game machine may also be used. can. Further, it is also possible to carry a thin plate glass for navigation, a thin plate glass for carrying a TV, and the like.

The rotation of the rotating body, the processing of the workpiece to be processed by the grinding of the workpiece, and the processing of the opening of the other workpiece holding portion Step of delivery; 8. Step of moving the traveling body holding the workpiece to be finished in the workpiece holding portion to the delivery position of the processing stage of the polishing unit; 9. Processing the polishing unit at the delivery position a step of collecting the workpiece that has been polished by the mounting table and receiving the workpiece by the other workpiece holding unit; 10. a step of rotating the rotating body and transferring the processed workpiece held by the one of the workpiece holding portions to the processing stage on which the workpiece to be polished is transferred; 11. Maintaining the workpiece a step of moving the traveling body of the workpiece to be polished until the discharge position of the discharge unit is completed; and 12. passing the polished workpiece to be held by the other workpiece holding unit The step of discharging the component discharge.

Further, the rotating body 25 has a substantially rectangular shape, but a rotating body 25 having a substantially hexagonal shape and a substantially octagonal shape as seen in the rotating shaft 37 may be employed. Further, the workpiece holding portion is not limited to being provided in two places, and the workpiece holding portion provided in three or more places is also a matter that can be appropriately designed and changed.

Further, in the above embodiment, the rotating body 25 has been described as being rotatable and reversible, but a rotating body which is rotatable only in one direction (non-rotatable in the other direction) is also within the intended scope of the present invention. However, as in the above-described embodiment, it is preferable to use a rotatable body that can be rotated and reversed, whereby there is no particular need for a means for preventing twisting of a cable attached to the rotating body, and the structure is simple.
