The pair of support bases 23 may be configured such that the relative distance can be adjusted on the base part 21. The support protrusion 25 may be configured such that the protrusion amount, height, and the like can be appropriately adjusted.

  In the support portion 17, the reference portions W <b> 2 of the workpiece W are brought into contact with the support protrusions 25, so that the processing target portion W <b> 1 faces upward as shown in FIG. 3. The workpiece W is positioned at the position. At this time, the position of the workpiece W shown in FIG. 2 in the longitudinal direction may be positioned at a predetermined position by, for example, the support base 23 and can be displaced in the longitudinal direction so that the workpieces W having different lengths can be supported. In the state, it may be configured to be supported by being aligned with a predetermined position of the support protrusion 25.

  As shown in FIG. 1, the suction unit 19 is attached to the tip of the first articulated arm 31 whose operation is controlled, and as shown in FIG. 4, the suction unit 19 is connected to the first articulated arm 31. A plurality of suctions provided with a base 33, a vacuum ejector 35 supported by the suction base 33, and suction openings 37 connected to the vacuum ejector 35 on one end side and suctioning the surface of the workpiece W on the other end side A pad 39 and a fixed rod 41 as a contact portion projecting from the suction base 33 to the plurality of suction pads 39 are provided.

  The first multi-joint arm 31 has a large number of joints 43 and is configured to be able to move the suction unit 19 in a three-dimensional direction and to rotate and tilt. The operation is controlled by a control unit (not shown). ing.

  A vacuum ejector 35 is provided for each suction pad 39, and the work W can be sucked by the suction opening 37 of the suction pad 39 by reducing the pressure in each suction pad 39.

  The suction pad 39 is formed to be hollow on the suction opening 37 side by an elastically deformable material such as rubber. In the suction pad 39, as shown in FIG. 5, the suction opening 37 is brought into contact with the surface of the work W and the inside is decompressed, so that the work W is sucked and elastically deformed toward the suction base 33. Further, the suction opening 37 side is elastically deformed to absorb irregularities on the surface shape of the workpiece W, and substantially the entire periphery of the suction opening 37 can be brought into close contact with the surface of the workpiece W.

  In this suction pad 39, the deformable amount of the suction opening 37 is formed to be at least larger than the unevenness of the surface of the workpiece W at the suction position in the vicinity of each processing target site W1, and the suction opening 37 side corresponds to the shape of the workpiece W during suction. Thus, it is formed to be elastic enough to be deformed.

  The fixed rod 41 is arranged so that the tip abuts against the surface of the work W when the surface of the work W is sucked by the suction pad 39. In this embodiment, three or more positions are provided apart from each other so that the tips of the fixed rods 41 are not arranged on the same straight line, and the surface of the workpiece W is sucked by the suction pad 39 and moved to the suction base 33 side. The workpiece W is arranged with respect to the adsorption base 33 by contacting the tip. In this state, it is possible to maintain a sufficiently fixed state without causing a displacement of the workpiece W during processing.

  The position of the tip of each fixed rod 41 corresponds to the three-dimensional shape of the surface of the workpiece W that faces each other during suction. In this embodiment, the protruding amount from the adsorption base 33 to the tip of the fixed rod 41 may be configured to be automatically or manually adjustable for each processing target site W1.

  The amount of protrusion from the adsorption base 33 at the tip of the fixed rod 41 is set to be shorter than the distance from the adsorption base 33 to the adsorption opening 37 and within the range in which the adsorption opening 37 of the adsorption pad 39 is deformed during adsorption. ing.

  Further, in this embodiment, a detection sensor capable of detecting a contact state such as a contact sensor or a pressure sensor is attached to the tip portion, and when the surface of the workpiece W is sucked by the suction portion 19, the detection sensor makes contact. By detecting the state, it is possible to detect whether or not the suction portion 19 is disposed at an appropriate position with respect to the workpiece W1 of the workpiece W.

  Although not particularly limited, in the suction portion 19 of this embodiment, the suction pad 39 has a diameter of 40 mm or more and the clearance Z between the end face of the suction opening 37 and the tip of the fixed rod 41 is 5 mm or more. The rubber hardness of the suction pad is preferably 50 degrees or more. Moreover, it is preferable that the pressure at the time of pressure reduction by the vacuum ejector is −75 KPa.

  Under such conditions, when the cutting resistance is set to 3 Kg at the time of machining described later, the positional deviation of the workpiece W at the processing target site W1 is measured. As shown in FIG. The deviation L in the height direction and the deviation H in the lateral direction perpendicular to the longitudinal direction could be ± 0.2 mm or less.

  In the fixing portion 11, each reference portion W2 of the work W is brought into contact with and supported by the support portion 17, and the suction portion 19 is moved by the first articulated arm 31, and the plurality of suction pads 39 are moved to the processing target portion W1. The surface of the workpiece W is brought into contact with both sides of the workpiece W to reduce the pressure, thereby attracting the surface of the workpiece W and thereby fixing the workpiece W.

  When the length of the hole or the like of the processing target portion W1 is larger than the distance between the plurality of suction pads 39, for example, the suction portion 19 is disposed obliquely or orthogonally to the processing target portion W1 of the workpiece W. Thus, the surfaces of the workpieces W on both sides of the processing target portion W1 may be sucked.

  Here, the workpiece W is supported from below by the support portion 17 and the surface of the workpiece W is adsorbed while pressing the workpiece W from the upper side to the lower side by the adsorption portion 19 by the operation of the first articulated arm 31. Therefore, the workpiece W is fixed in a state of being sandwiched between the support portion 17 and the suction portion 19.

  If the workpiece W is sandwiched between the support portion 17 and the suction portion 19 in this way, the workpiece W may be bent or slightly expanded in the longitudinal direction when fixed. Therefore, even if the end portion of the workpiece W is positioned at the reference position X as shown in FIG. 7A after being positioned on the support portion 17, the end portion of the workpiece W is shifted from the reference position X in the longitudinal direction after fixing. May occur. In such a case, for example, as shown in FIG. 8, the end of the workpiece W may be sucked by the suction auxiliary pad 45 from the inside so as to prevent displacement.

  Next, the processing unit 15 of the resin workpiece processing apparatus 10 is attached to the second articulated arm 32 whose operation is controlled, and the processing connected to the second articulated arm 32 as shown in FIG. A base portion 47, a spindle portion 49 that is mounted on the processing base portion 47 and driven to rotate, and a processing tool 13 that rotates in conjunction with the spindle portion 49 are provided. In the present embodiment, an end mill is mounted as the processing tool 13 in order to process the inner peripheral surface of the hole that is the processing target portion W1.

  The second multi-joint arm 32 has a large number of joint portions 43 and is configured to be able to move the processing portion 15 in a three-dimensional direction and to rotate and tilt. The second articulated arm 32 is controlled by a control portion (not shown). Yes.

  In the processing unit 15, the processing tool 13 can be arranged so as to face the suction unit 19 attached to the first articulated arm 31, and the suction unit 19 is arranged on the surface side of the workpiece W. In this state, it is possible to perform machining by bringing the machining tool 13 into contact with the machining target portion W1 from the back side of the workpiece W.

  And in this process part 15, each process object site | part W1 arrange | positioned between the some suction pads 39 is controlled by the control part by the control part etc. by the rotation speed of the process tool 13, a 2nd articulated arm, etc. Can be cut under predetermined cutting conditions.

  Next, a method for manufacturing a resin processed product by processing the workpiece W using the resin processing apparatus 10 having such a configuration will be described. In this embodiment, each workpiece W is provided with a larger number of processing target portions W1 than the number of suction portions 19 and processing portions 15.

  In order to process the workpiece W by the resin workpiece processing apparatus 10, the workpiece W is placed on the support portion 17 of the fixed portion 11, and the workpiece W is fixed by the support portion 17 and the suction portion 19 of the fixed portion 11. It is processed by the part 15.

  In order to support the workpiece W on the support portion 17, as shown in FIG. 2, the workpiece W that has been molded in advance is carried in from the previous step, and each reference portion W <b> 2 is placed with the workpiece portion W <b> 1 facing upward. The support protrusions 25 are placed in contact with each other. As a result, the workpiece W is positioned at a predetermined position.

  After the positioning, as shown in FIGS. 10 and 11, the fixing unit 11 and the processing unit 15 are controlled and operated by a control unit (not shown).

  When the control of the fixing unit 11 and the processing unit 15 is started, the fixing unit 11 is controlled as shown in FIG. 11 (a), and the processing unit 15 is controlled and operated as shown in FIG. 11 (b). . Here, after the start, the first multi-joint arm 31 and the second multi-joint arm 32 operate, and each of the suction unit 19 and the processing unit 15 is moved to a position corresponding to one of the plurality of processing target sites W1. Move (S11, S21).

  And in the fixing | fixed part 11, each suction pad 39 is earth | grounded on the surface of the workpiece | work W in the vicinity of the process target site | part W1 (S12), and adsorption | suction is started (S13).

  In the processing unit 15, after detecting that the fixing unit 11 has reached the fixing completion state (S22), the processing tool 13 is brought into contact with the processing target portion W1 of the workpiece W to perform cutting (S23) and shape processing (S24). I do. Thereafter, by driving the second articulated arm 32, the processing tool 13 is separated from the processing target portion W1 and is released (S25).

  In the fixing unit 11, after detecting that the machining tool 13 has been released in the processing unit 15 (S14), the suction is finished and the fixing is released (S15).

  While the processing of all the processing target portions W1 provided on the workpiece W is not completed, the first multi-joint arm 31 and the second multi-joint arm 32 are operated and suctioned as shown in FIG. The part 19 and the processing part 15 are moved to positions corresponding to the next processing target part W1 (S11, S21), and the processing target part W1 is sequentially processed by repeating the above-described steps again.

  By repeating such movement, adsorption and processing of the fixed portion 11 and the processing portion 15 and finishing the processing of all the processing target portions W1 (S16, S26), the processing of one workpiece W is completed, and the support portion The bumper which is a resin-made processed product is manufactured by removing the workpiece | work W from 17 and performing an appropriate post-processing, a process, etc. from above.

  Thereafter, when another workpiece W having a different shape is processed, if the workpiece reference portion W2 is the same, the support portion 17 is maintained as it is, and the first multi-joint arm 31 and the second multi-joint arm 31 are maintained. Each part W1 to be processed can be processed by the same method as described above by changing the operation of the joint arm 32, the positions of the suction part 19 and the processing part 15 and various conditions as necessary.

  Further, when the position of the reference part W2 in another workpiece W is different, by adjusting the positions of the support portion 17 and the support protrusion 25, it is possible to fix each of the processing target parts W1 in the same manner as described above. it can.

  By doing in this way, in the resin workpiece processing apparatus 10 of this embodiment, various resin workpieces can be processed and a resin processed product can be manufactured.

  According to the resin workpiece processing apparatus 10 as described above, since the workpiece W is fixed by bringing the reference portion W2 of the workpiece W into contact with the support portion 17, the positional accuracy of the workpiece portion W1 with respect to the reference portion W2 is ensured. In addition, since the surface of the workpiece W in the vicinity of the processing target portion W1 is sucked by the suction portion 19 to fix the workpiece W, the processing target portion W1 of the workpiece W can be easily and reliably fixed during processing. it can. Therefore, the processing target portion W1 can be processed with high accuracy.

  If the workpiece W is fixed between the reference portion W2 and the vicinity of the processing target portion W1, the processing target portion W1 can be processed by the processing portion 15. Therefore, even if the workpieces W have different shapes, the common support portion 17 and the suction portion 19 are used. Can be fixed and processed, and the support part 17 and the suction part 19 can be easily used in common, and versatility can be improved.

  Here, in the workpiece W in which the reference part W2 is provided on both ends and the workpiece part W1 is provided between the reference parts W2, a part that is not supported by the support part 17 is sucked and fixed by the suction part 19. Therefore, the work W fixing structure can be simplified and fixed easily.

  And since it is not necessary to support the wide range of the workpiece | work W, fixation is easy and it is not necessary to use a different special jig for every shape of the workpiece | work W. FIG. For this reason, it is not necessary to set up or replace a dedicated work receiving jig during processing, and the work time required for the setup can be shortened. In addition, since it is not necessary to use many types of workpiece receiving jigs, it is not necessary to prepare or store other types of workpiece receiving jigs.

  In this processing apparatus 10, the suction unit 19 is attached to the first articulated arm 31 whose operation is controlled, and the processing unit 15 is attached to the second articulated arm 32 whose operation is controlled. And the freedom degree of operation | movement of the process part 15 is large, can process the resin-made workpiece | work W which exhibits various shapes, and can improve versatility.

  Further, since the fixed portion 11 is configured to sandwich the workpiece W between the support portion 17 and the suction portion 19, the suction portion is in a state in which the reference portion W <b> 2 of the workpiece W is securely in contact with the support portion 17. 19 can suck and fix the workpiece W. Therefore, it can process stably and accurately.

  In addition, since the workpiece W can be fixed by the suction force and the clamping force, the suction force of the suction portion necessary for preventing positional displacement during processing can be suppressed to a low level. That is, if the workpiece W is held only by the suction portion 19 during processing, the suction force and the rigidity of the suction portion 19 are required to resist various forces applied during processing. Further, if the workpiece W is fixed only by being sandwiched between the reference portion W2 and the vicinity of the processing target portion W1, the resin workpiece W is deformed and the processing accuracy is lowered. However, if the workpiece W is sucked by the suction portion 19 and is sandwiched between the suction portion 19 and the support portion 17, it is not necessary to excessively increase the suction force and rigidity of the suction portion 19, and the deformation of the resin workpiece W is prevented. Therefore, it is possible to reliably prevent movement during processing, and it is possible to perform processing accurately with a simple structure.

  In addition, in the fixed portion 11, the suction portion 19 includes the fixed rod 41 that comes into contact with the surface of the workpiece W while the surface of the workpiece W is sucked. Therefore, the surface of the workpiece W is in contact with the fixed rod 41. By adsorbing, the workpiece W can be accurately placed at a predetermined position. In addition, since the relative position between the processing target site W1 and the suction portion 19 can be confirmed while the fixed rod 41 is in contact, it is possible to prevent the displacement of the workpiece W.

  According to the method of manufacturing a resin processed product as described above using such a resin workpiece processing apparatus, the workpiece W is fixed by bringing the reference portion W2 of the workpiece W into contact with the support portion 17, and thus the workpiece to be processed. The part W1 can be processed accurately with respect to the reference part W2. Furthermore, since the workpiece W is fixed by adsorbing the surface of the workpiece W in the vicinity of the processing target site W1, the workpiece W is securely fixed by preventing positional displacement when machining with the machining tool 13. Can do. Therefore, if the reference portion W2 can be brought into contact with the support portion 17 and the vicinity of the processing target portion W1 can be adsorbed, the processing target portion W1 can be processed with high accuracy without supporting a wide range of the workpiece W.

  Moreover, in such a manufacturing method, the workpiece W has a plurality of processing target parts W1, and by moving the suction parts 19 and the processing parts that are smaller in number than the plurality of processing target parts W1, the suction and processing are performed. Since each processing target portion W1 is processed, a plurality of processing target regions can be processed without re-supporting the workpiece W on the support portion 17 for each processing target portion W1, thereby simplifying setup time and processing time. The resin processed product can be manufactured efficiently.

  The above embodiment can be modified within the scope of the present invention. For example, in the above description, an example of processing a resin bumper for a vehicle has been described. However, the present invention can be similarly applied to other members.

Furthermore, the same effect can be obtained by applying the present invention as long as the workpiece is easily deformed and the portion to be fixed at the time of processing is likely to be widened similarly to the resin workpiece.
[Second Embodiment]
FIG. 13 shows a part of the resin workpiece processing apparatus 10 of the second embodiment.

  In the processing apparatus 10 of the second embodiment, the suction unit 19 and the processing unit 15 are attached to the same articulated arm 55 whose operation is controlled, and the suction unit 19 and the processing unit 15 are connected as in the first embodiment. It is different from being separately attached to the first articulated arm 31 and the second articulated arm 32, respectively.

In this processing apparatus 10, the suction portion 19 is configured by a suction pad 39 provided on the suction processing base 51 at the tip of the articulated arm (not shown) so that the surface of the workpiece W can be sucked, as in the first embodiment.
The processing unit 15 is provided with a three-axis servo mechanism 53 on the opposite side of the suction processing base 51 from, for example, the suction pad 39, and a spindle unit 49 that is rotationally driven by the three-axis servo mechanism 53 and a spindle unit 49. The processing tool 13 is mounted on the.

  In the triaxial servo mechanism 53, a pair of first guide rails 57 is provided in the uniaxial direction on the suction processing base 51, and a second guide rail 59 orthogonal to the first guide rail 57 is movable along the first guide rail 57. The spindle portion 49 is provided on the suction pad 39 side so as to be able to project and contract. The three-axis servo mechanism 53 is operable by controlling the machining tool 13 in a three-dimensional direction and a tilting direction with respect to the workpiece W by a drive mechanism (not shown).

  Other configurations are the same as those of the first embodiment.

  Even with the resin workpiece processing apparatus 10 of the second embodiment having the suction section 19 and the processing section 15 having such a configuration, it is possible to obtain the same effects as those of the first embodiment.

  In particular, in this processing apparatus 10, since the adsorption | suction part 19 and the process part 15 are mounted | worn with the same articulated arm, the structure of the processing apparatus 10 can be simplified.
