Therefore, the side-play amount of computing machined object more exactly.That is, because " mechanical origin " error, therefore can reduce the computing of side-play amount near the position of centre of gravity of machined object the time can calculate more accurately side-play amount thus.Thereby can carry out the processing of more high-precision machined object.

In addition, preferably, described machine table is arranged to select and to arrange a plurality of the first maintenance platforms, is reached the second either party who keeps in the platform, wherein said a plurality of first keeps platform can keep small-sized machined object respectively, described second keeps platform can keep large-scale machined object, described benchmark position be configured in than arrange first keep the small-sized machined object that platform keeps by first when keeping platform and arrange second when keeping platform by equal in the outer part the position of the second profile that keeps any machined object in the large-scale machined object that platform keeps.

Thus, keep platform owing to arranging a plurality of first in machine table, therefore for small-sized machined object, can keep a plurality of machined objects by a machine table.In addition, owing to can selecting first to keep platform and second to keep platform to be arranged on the machine table, therefore can utilize with the big or small corresponding maintenance platform of machined object suitably and reliably to keep machined object.

And then even keeping platform and second to keep in the platform any to be arranged in the situation of machine table with first, because the benchmark position is positioned at the outside of the profile of machined object, so machined object can not block the benchmark position.Therefore, when arranging the side in the first maintenance platform and the second maintenance platform is altered to the opposing party, need not to change the benchmark position in the outside that is arranged in as mentioned above any large-scale and small-sized machined object, can simplify the structure of machine table.

In addition, preferably adopt following structure, that is, described machine table possesses a plurality of maintenance platforms that keep respectively machined object, and described benchmark position is provided with a plurality of, and this a plurality of benchmark position is configured in respectively the outside of the profile of each machined object that is kept by described a plurality of maintenance platforms.

Thus, can a plurality of maintenance platforms be set in machine table, keep a plurality of machined objects by a machine table.

In addition, because at the arranged outside benchmark position of each machined object that is kept platform to keep, so the benchmark position is positioned at the position near machined object by each, therefore, " mechanical origin " near the position of centre of gravity of machined object, the error in the time of can reducing the computing of side-play amount.

This grinding attachment M has the controlling organization of control exercises.Here, as controlling organization, can be consisted of by for example electronic control unit.

Controlling organization is the mechanism that carries out following control, that is, utilizes conveyance to take out of unit 10 unprocessed workpiece W supplied with to machine table 103, and the workpiece W that machines is taken out of from machine table 103, below, illustrate that the conveyance that this grinding attachment M carries out takes out of method.

At first, when beginning grinding operation, the top side that unit 10 is positioned at the first track 11 is taken out of in conveyance.And feed unit 60 receives unprocessed workpiece W from workpiece cassette 61, and feed unit 60 will this unprocessed workpiece W be taken out of machined object maintaining part 27 from a side of unit 10 to conveyance joins.Need to prove, when this joins, conveyance is taken out of the machined object maintaining part 27 of unit 10 and feed unit 60 the adsorption section attraction and stop to control.Also carry out such attraction and the control that stops when the handing-over of workpiece W described later, below description is omitted.

The delivery position that unit 10 moves to a grinding unit 100 in a plurality of grinding units 100 is taken out of in the conveyance that receives unprocessed workpiece W.Need to prove, at this moment, the machine table 103 of this grinding unit 100 also moves to delivery position.

Then, rotary body 25 half-twists make the machined object maintaining part 27 that maintains workpiece W towards lower side, and workpiece W and machine table 103 are faced mutually.Then, rotary body 25 descends and workpiece W is joined to machine table 103.

Afterwards, rotary body 25 rotation (counter-rotating)-90 ° utilize the workpiece W on the camera 23 shooting machine table 103.

After the shooting, machine table 103 moves and begins the grinding operation to Working position, and conveyance is taken out of unit 10 to the starting point side shifting of the first track 11.

Each grinding unit 100 is carried out conveyance operation as described above, and supply with workpiece W to each grinding unit 10.

And when the grinding operation in the above-mentioned grinding unit 10 was finished, machine table 103 moved to delivery position.In addition, conveyance is taken out of unit 10 and is maintained the mobile supreme delivery position of stating under the state of unprocessed workpiece W in the machined object maintaining part 27 of a side.Need to prove, at this moment, the machined object maintaining part 27 of opposite side is in the not Light Condition of holding workpiece W.

Afterwards, rotary body 25 rotation (counter-rotating)-90 ° make the machined object maintaining part 27 of the above-mentioned opposite side of holding workpiece W not towards lower side, and workpiece W and machine table 103 are faced mutually.Then, rotary body 25 descends and receives the workpiece W that machines from machine table 103.

Then, rotary body 25 Rotate 180s ° make the machined object maintaining part 27 that maintains workpiece W towards lower side, and workpiece W and machine table 103 are faced mutually.Then, rotary body 25 descends and workpiece W is joined to machine table 103.

Then, in the starting point rear flank that moves to the first track 11, deliverying unit 70 is taken out of the opposite side of unit 10 from conveyance machined object maintaining part 27 receives the workpiece W that machines, and the workpiece W that these machine is housed in the workpiece cassette 61 that machines workpiece W, and, feed unit 60 receives unprocessed workpiece W from the process cartridge 61 of unprocessed workpiece W, and these unprocessed workpiece W is taken out of machined object maintaining part 27 handing-over of a side of unit 10 to conveyance.

The delivery position that unit 10 moves to another grinding unit 100 of having finished the grinding operation is taken out of in the conveyance that receives so unprocessed workpiece W, repeatedly carries out conveyance as described above and takes out of operation.

In addition, controlling organization is based on the data that photographed by camera 23, and the grinding path of computing workpiece W utilizes Figure 14～Figure 15 that the control method of this arithmetic expression is described.

Shown in the flow chart of Figure 14, like that, after the beginning, at first in S1, the model data (profile, hole section etc.) of workpiece W is inputted (installation) in electronic control unit (input operation).In this input operation, the design data (cad data) of the workpiece Wo that for example will accurately process temporarily is taken in other software, these data transaction is become the backward electronic control unit inputs of grinding data (installation) in grinding path etc.

After such input end of job, next in S2, to machine table 103 mountings (moving into), and make workpiece Wi keep (maintenance operation) by absorptive table 108 the workpiece Wi of reality (below, be called practical work piece W).

Afterwards, in S3, utilize camera 23 to be taken into practical work piece Wi and reference pins 116,116 image (shooting operation).Particularly, utilize camera 23 to take workpiece Wi and the reference pins 116,116 of machine table 103.By the such position of leaving from the top taking machine table 103, thereby can reduce as much as possible the deviation of the workpiece Wi that is taken into and reference pins 116,116 view data.

Figure 15 (a) is the figure that represents the example of the view data that is taken into like this.Workpiece Wi and two reference pins 116,116 are taken into as view data, calculate position data separately.

Then, in S4, the mechanical origin C (mechanical origin is calculated operation) that calculates machine table 103 according to reference pins 116,116 position.Here, mechanical origin refers to the benchmark be used to the mechanical coordinate that carries out grinding, by stipulating this mechanical origin C, can carry out accurate grinding.

Like that, mechanical origin C is decided to be the mid point that links two reference pins 116,116 line L shown in Figure 15 (b).In addition, as other example, also can be shown in dotted line like that, append again two reference pins 116 ', 116 ', and two reference pins 116 that link is appended ', 116 ' line N be defined as mechanical origin C with the intersection point that links above-mentioned two reference pins 116,116 line L.

Then, in S5, calculate the center P of profile Wa of practical work piece Wi and the position of centre of gravity Q (position of centre of gravity is calculated operation) of the Wb of hole section according to the data of the practical work piece Wi that is taken into.Here, position of centre of gravity refers to the position of the center of gravity of figure, determines by outer shape and the hole section shape of workpiece W.Black circle P, Q shown in Figure 15 (b) represents respectively the position of centre of gravity of profile Wa of practical work piece W and the position of centre of gravity of the Wb of hole section.

Afterwards, in S6, make the position of centre of gravity (the position of centre of gravity P of profile and the position of centre of gravity Q of hole section) of practical work piece Wi consistent with the position of centre of gravity (the position of centre of gravity Pm of profile and the position of centre of gravity Qm of hole section) of model Wm.Consistent with position of centre of gravity Pm, the Qm of model Wm by the position of centre of gravity P, the Q that make practical work piece Wi (original text is wrong), thereby clear and definite practical work piece Wi and model Wm poor (position data poor).State shown in Figure 15 (c) is the position of centre of gravity state consistent with position of centre of gravity P, Q, Pm, the Qm of model Wm (single-point line) that makes practical work piece Wi.By making like this position of centre of gravity P, Q, Pm, Qm consistent, thus can clear and definite practical work piece Wi and model Wm poor.

Then, in S7, compare the mechanical origin C of machine table 103 and the position of centre of gravity P of practical work piece Wi, thereby side-play amount (the horizontal offset X of the position of centre of gravity P of computing mechanical origin C and practical work piece Wi, side-play amount Y longitudinally, the side-play amount θ of direction of rotation) (side-play amount operational process).In addition, compare practical work piece Wi and model Wm, thereby computing is because of poor caused the cutting into amount Δ w of profile.Like this, stock removal that can clear and definite practical work piece Wi.

Figure 15 (d) represents side-play amount separately and cuts into amount.The position of centre of gravity P of practical work piece Wi for example illustrates like that apart from the side-play amount of the mechanical origin C of machine table 103, is offset to the left X, and upwards lateral deviation is moved Y, also cant angle theta to the right.

And, in the amount of cutting, cutting into amount Δ w1 by the difference of the width dimensions T1 of the width dimensions r1 of practical work piece Wi and model is calculated divided by 2 of width, the cutting into amount Δ w2 by the difference of the length dimension T2 of the length dimension r2 of practical work piece Wi and model is calculated divided by 2 of length direction.

Like this, obtain out the amount of cutting Δ w1, the Δ w2 of width and length direction after, wherein large value is defined as final cutting into amount Δ w.The reason of determining like this is, when carrying out grinding, adopts the track similar to mould shapes, with certain amount of cutting workpiece W complete cycle cut into, therefore by being defined as large value, can produce reliably cut into, thereby can be ground to more shape near mould shapes.

Then, in S8, according to the side-play amount of X, Y, θ and cut into amount Δ w, calculate the grinding path (grinding path operational process) of workpiece Wi.This grinding path root factually the mounting position of shape, the practical work piece Wi of border workpiece Wi change and change, so the grinding path of each workpiece W is different.

Afterwards, in S9, by the grinding path of calculating practical work piece Wi is carried out grinding (grinding process).This grinding operation is by making respectively grinding spindle 131 and machine table 103 move to carry out.In the grinding operation of this workpiece W, use the machining tool 130A in above-mentioned large footpath or the machining tool 130B of above-mentioned path to carry out according to the grinding position.

At last, in S10, practical work piece Wi is taken out (taking out of operation) as described above from machine table 103.

Next, judge in S11 whether operation finishes, in the situation (being judged as no situation) that operation continues, again shift to above-mentioned S2, to process next workpiece W.On the other hand, the situation in the end of job (is judged as the situation that is: the situation that power supply disconnects), directly shift to end.

As described above, utilize this grinding attachment M end face to workpiece W under the control of above-mentioned controlling organization to carry out grinding, thereby can make the lamellar member that end face has been carried out grinding.

Among this grinding attachment M, machined object maintaining part 27 is arranged on two positions, takes out of unit 10 by a conveyance and can roughly discharge continuously step and conveyance step, thereby can enhance productivity.

Special in the situation that have a plurality of grinding units 100, in a grinding unit 100, carry out conveyance as described above and take out of between operational period, can in other grinding unit 100, carry out the grinding operation, thereby can further boost productivity.

And, feed unit 60 and deliverying unit 70 are provided on the position that clips the first track 11, opposed walls at rotary body 25 is respectively equipped with machined object maintaining part 27, can carry out simultaneously as described above thus the supply of 60 couples of unprocessed workpiece W of feed unit and the discharge of the workpiece W that 70 pairs of deliverying units machine, thereby the time is taken out of in the conveyance of shortening workpiece W, further boosts productivity.

And then, in this grinding attachment M, owing to having a plurality of absorptive tables 108 that can distinguish holding workpiece W in machine table 103, therefore utilize processing operation once just can carry out the grinding of a plurality of workpiece W.And, because the machined object maintaining part 27 at two positions has respectively a plurality of machined object retaining members 29 corresponding with the absorptive table 108 of above-mentioned machine table 103, therefore utilize once conveyance to take out of operation and just can conveyance take out of a plurality of workpiece W.Therefore, can further realize the raising of generation rate.Especially when time processing operation for example, process in the situation that utilize multiple machining tool, install after a kind of machining tool, utilizing this machining tool to carry out processing of the same race to a plurality of workpiece W processes, afterwards, pull down above-mentioned the sort of machining tool and the machining tool of other kind is installed, thereby utilize the machining tool of other kind that above-mentioned a plurality of workpiece W are carried out processing processing of the same race.That is, the processing that utilizes dismounting machining tool just can carry out a plurality of workpiece is processed, and therefore can shorten the needed time of dismounting of machining tool, thereby can realize the raising of operating efficiency.

And then, because machine table 103 moves to Working position from delivery position by the second track 101, therefore the Working position state moistening because grinding fluid becomes can mark off the zone of handing-over workpiece W and the zone that processes, even also can be distinguished delivery position from this moisture state.In addition, the unprocessed workpiece W that the side in two machined object maintaining parts 27 is only kept dry, the opposing party only keeps the moistening workpiece W that machines, thereby can distinguish the moistening or drying regime of each machined object maintaining part 27.

And then, move and machine table 103 moves such simple structure along the second track 101 along the first track 11 owing to being moving body 13, therefore compare with the situation that adopts existing scalar robot, can suppress expensive and be difficult for initiating failure, also easily safeguard.

In addition, therefore relatively simple for structure owing to rotary body 25 is to move up and down the structure that is toward or away from machine table 103 sides in moving body 13, can prevent the expensive and difficult generation fault of locking apparatus etc., also easily safeguard.

In addition, in this grinding attachment M, a plurality of grinding units 100 all are adapted to Working position and are positioned at the same side with respect to the first track 11, therefore in a side of the Working position that grinding unit 100 is not set, can set above-mentioned the first track 11 in the side of device, have advantages of that the repairing of conveyance unit and inspection etc. easily carry out such.

In addition, because feed unit 60 and deliverying unit 70 are arranged near the top of the first track 11, therefore can configure in the side (side of the top side of the first track 11) of grinding attachment M supply portion and the discharge section of workpiece W.Therefore, operator just can carry out

workpiece cassette

61,71 input or taking-up from side's side.

In addition, at moving body 13 camera 23 is installed and takes workpiece W on the machine table 103, can carry out grinding operation under the grinding path accurately according to this photographed data.

Especially, because the data of the model of workpiece W being installed in advance, the mechanical origin of calculating machine table 103 according to the photographed data of the reference pins 116 that is taken into by camera 23, and obtain the position of centre of gravity of workpiece W according to the photographed data of the workpiece W that is taken into by camera 23, compare the mechanical origin of machine table 103 and the position of centre of gravity P of workpiece W, thereby calculate the side-play amount of workpiece W, come computing grinding path according to this side-play amount, therefore can carry out grinding to workpiece W exactly.Especially, even owing to certainly not forming " as the mark (mark) of benchmark " with it at workpiece W, also can obtain " mechanical origin " by the reference pins that is arranged on the machine table 103, can grasp the side-play amount of workpiece W, therefore the sheet glass (workpiece W) that uses in the display frame for portable terminals such as portable phones also can carry out grinding reliably.

In addition, considering has the mode that many cameras 23 is set and each machine table 103 is set camera 23, but by adopting camera 23 is installed in structure on the moving body 13 as described above, thereby need not to arrange many cameras 23, can restraining device expensive.

And then, because camera 23 is positioned at the top of moving body 13, therefore can increase camera 23 and distance as the workpiece W of reference object, can focusing thus, it is whole to take well workpiece W.

In addition, owing to can select arrange in machine table 103 absorptive table 108 of a plurality of kinds, therefore can be according to the size as the workpiece W of grinding object, select the absorptive table that is fit to and carry out exactly the grinding operation.And then, in the situation that being fixed with the first or the 3rd, mounting keeps base station 107, can a plurality of absorptive tables 108 be set in machine table 103.Thus, can be in the situation that do not change and keep base station 107 to select to be more suitable in the absorptive table 108 of the size of the W of workpiece, thus carry out the grinding operation.

In addition, owing to having a plurality of reference pins 116, these a plurality of reference pins 116 are configured in respectively the outside of the profile of each workpiece W that absorptive table 108 keeps, therefore reference pins 11 is positioned at the position near workpiece W, therefore, " mechanical origin " becomes near the position of centre of gravity of workpiece W, the error in the time of can reducing the side-play amount computing.And then, because said reference pin 116 is positioned at two side positions that clip each workpiece W, therefore the point that links on the line of reference pins 116 of both sides of workpiece W can be made as " mechanical origin ", the position near the position of centre of gravity of workpiece W can be made as mechanical origin thus.And, clip workpiece W and opposed at least two pairs of reference pins 116 owing to disposing, therefore be made as " mechanical origin " by linking each intersection point to the line of reference pins 116, can make thus the position of centre of gravity of this mechanical origin and workpiece W more approaching.Therefore, the side-play amount of computing workpiece W more accurately.

And then, because erectting the reference pins 116 that is arranged on the above-mentioned base station plate 109 is positioned at than the profile position in the outer part that remains on the workpiece W on the absorptive table 108, therefore reference pins 116 can not blocked by workpiece W, even thereby change is set to a certain in first, second and third absorptive table 108, also need not to replace this reference pins 116, can take exactly operation.Therefore, can make the simple in structure of machine table 103.

Need to prove, the utility model is not limited to above-mentioned embodiment, can suitably carry out design alteration in the represented scope of the utility model.

In the grinding attachment M of above-mentioned embodiment, the sheet glass that uses portable phone to use is workpiece W as machined object, but the sheet glass that can use portable audio equipment to use, the sheet glass that can also use portable game machine to use.And then, also can use the sheet glass that portable navigation uses, sheet glass of portable TV etc.

In addition, the overall structure of grinding attachment M is not limited to above-mentioned embodiment, otherwise is that a mode with a plurality of grinding units such as five or six all is included in the represented scope of the utility model such as grinding unit.

And then in the above-described embodiment, the mode of only carrying out grinding operation of the same race to grinding unit is set in each grinding unit is illustrated, but this aspect is not limited thereto, and can adopt and carry out the mode that different processing is processed in each machining cell.Namely, for example possess not only that above-mentioned embodiment is described to be conceived to dimensional accuracy and to the grinding unit that the end face of workpiece grinds, the grinding attachment that also possess the grinding unit that the end face of workpiece ground a little in order to obtain desired surface roughness, carries out the perforation processing unit of perforate with the workpiece butt is also included within the represented scope of the utility model.
