(Embodiment 1)
<Jig set>
FIG. 1A is a schematic perspective view showing a jig set 40 including the case 2 and the jig 1 according to the first embodiment. FIG.1 (b) is a schematic perspective view which shows the state with which the jig | tool set 40 of Fig.1 (a) was combined.
A jig set 40 according to the first embodiment includes a jig 1 (first jig) including the RFIC element 20 and a case 2 (second jig) including the antenna elements 10 (11, 12). Is done. The antenna element 10 includes a first antenna element 11 and a second antenna element 12, and can be electrically connected to the RFIC element 20 when the case 2 and the jig 1 are combined. The RFIC element 20 and the antenna element 10 constitute an RFID tag 30.
Therefore, when the case 2 and the jig 1 are combined, it is determined whether or not communication with the RFID tag 30 including the RFIC element 20 and the antenna element 10 is possible. Thereby, in addition to the two-dimensional positional deviation in the XY plane between the case 2 and the jig 1, a three-dimensional positional deviation including the positional deviation in the Z direction can be detected.

  Below, the structural member which comprises this jig | tool set 40 is demonstrated.

<First jig>
The first jig 1 is an auxiliary tool that facilitates machining of a workpiece, or is used for mass production and refinement. For example, there are fixtures, fixtures, molds and the like used in machining, welding, injection molding, other manufacturing processes, inspection processes, and the like. Specifically, the first jig 1 may include a cover, a holding jig, an upper mold, and the like.
Further, the first jig 1 is provided with an RFIC element 20 on the surface of the first jig 1 that constitutes the abutting surface when the first jig 1 and the second jig 2 are combined.

<Second jig>
The second jig 2 is a jig that forms a pair with the first jig 1, and is used in, for example, machining, welding, injection molding, other manufacturing processes, inspection processes, and the like, similar to the first jig. Fittings, fixtures, molds etc. Specifically, the second jig 2 may include a case, a pedestal, a lower mold, and the like. The first jig 1 and the second jig 2 only need to form a jig set to form a jig set, and do not limit the size relationship of each other. Further, the first jig 1 and the second jig 2 may be interchanged with each other.
The second jig 2 is provided with an antenna element 10 that can be electrically connected to the RFIC element 20 when combined with the first jig 1. Specifically, the antenna element 10 is provided on the surface of the second jig 2 that constitutes the abutting surface when the first jig 1 and the second jig 2 are combined.

<RFIC element>
FIG. 2 is a schematic cross-sectional view showing a configuration of a combination of the RFIC element 20 and the antenna element 10 of FIG. FIG. 3 is an equivalent circuit diagram of the RFIC element 20 of FIG.
The RFIC element 20 includes an RFIC chip 21 and a multilayer substrate 25 connected to the RFIC chip 21 via a conductive bonding material 22 and a terminal electrode 23. The RFIC chip 21 is sealed with a sealing resin 24. In addition, the multilayer substrate 25 has a built-in power supply circuit including an L pattern such as L1 and L2 and a C pattern such as C1 and C2. C _IC is a stray capacitance of the RFIC chip 21. A resonance circuit is formed by the power feeding circuit, and the resonance frequency corresponds to the carrier frequency. By providing the feeding circuit in this way, the center frequency of the carrier frequency can be prevented from changing greatly even if the electrical length of the antenna element changes.
That is, if the electrical length of the antenna element 10 in the initial state is matched with the maximum gain state (2 / λ), the communicable distance is reduced even if the electrical length of the antenna element 10 is slightly changed, and the same carrier. Reading by frequency is possible.

  For example, in FIG. 2, the RFIC element 20 and the first and second antenna elements 11 and 12 are connected to the first antenna element 11 by the terminal electrode 26a of the RFIC element 20 and are connected to the second antenna element by the terminal electrode 26b. Although connected by direct connection, it is not limited to this. The RFIC element 20 and the first and second antenna elements 11 and 12 may be coupled not only directly by the terminal electrodes 26a and 26b but also by any coupling such as capacitive coupling and magnetic field coupling. An example of magnetic field coupling is shown below.

FIG. 4A is an equivalent circuit diagram when the RFIC element 18 and the antenna element 14 are magnetically coupled. FIG. 4B is a schematic diagram showing a state of magnetic coupling between the loop antenna 28 of the RFIC element 18 and the loop portion 16 of the antenna element 14 in the case of FIG.
In this embodiment, the RFIC element 18 has the same configuration as the RFIC element 20 in the above embodiment. However, the RFIC element 18 in the present embodiment does not have a configuration corresponding to the multilayer substrate 25. The antenna element 14 has a configuration in which, for example, a central portion of a wire-like metal wire is formed in a loop shape, and both end sides are open ends extending in opposite directions.
As shown in FIGS. 4A and 4B, the loop antenna 28 and the loop portion 16 are connected by aligning the axes of the loop antenna 28 of the RFIC element 18 and the loop portion 16 of the antenna element 14 in parallel or coaxially. The magnetic field lines 17 penetrate and can be magnetically coupled. Note that the RFIC element 18 in this case does not include any capacitance other than the stray capacitance C _IC of the RFIC chip 21. The antenna element 14 has a radiating portion extending from the loop portion 16 to both sides in opposite directions.
In FIG. 2, the RFIC element 20 is provided with the multilayer substrate 25 containing the power feeding circuit, but the present invention is not limited to this, and the power feeding circuit may not be provided.

<Antenna element>
The antenna element 10 includes a first antenna element 11 and a second antenna element 12. The first antenna element 11 and the second antenna element 12 have an elongated rectangular shape or a bar shape (bar shape). The first antenna element 11 and the second antenna element 12 extend in different directions. Specifically, the first antenna element 11 and the second antenna element 12 extend in directions opposite to each other. The antenna element 10 is not limited to the case where the antenna element 10 is configured by the first antenna element 11 and the second antenna element 12 as described above. For example, the antenna element 10 may be configured with either the first antenna element 11 or the second antenna element 12.
The first antenna element 11 and the second antenna element 12 can be made of a material such as a copper foil, a copper plate, a copper plating film, a gold foil, a gold plate, or a gold plating film used for a normal antenna element. The material is not limited to the above example, and any material that is normally used can be used.

<Division of RFIC element and antenna element>
The jig set 40 does not include the RFID tag as it is, but the RFIC element 20 and the antenna element 10 constituting the RFID tag are arranged in each jig in a divided structure. It is a feature. That is, the “RFIC element 20” is provided on the surface of the jig 1 that constitutes the abutting surface when the jig 1 as the first jig and the case 2 as the second jig are combined. The “antenna element 10” is provided in the case 2 that constitutes a butt surface when the jig 1 as the first jig and the case 2 as the second jig are combined. As a result, the RFIC element 20 provided in the jig 1 and the antenna element 10 provided in the case 2 can be electrically connected only when the jig 1 and the case 2 are correctly combined, and the RFID tag 30 is configured. RFID communication is possible. In this case, even when the abutting surface between the jig 1 and the case 2 is deviated in the plane, the relative position between the RFIC element 20 and the antenna element 10 is deviated, and the RFID tag is not configured. Further, the RFID tag is not configured even when the butting surface between the jig 1 and the case 2 is separated in the normal direction. That is, in this jig set 40, the RFIC element 20 and the antenna element 10 are arranged on the mutually facing surfaces of the butted surfaces of the jig 1 and the case 2, respectively. As a result, the RFID tag is not configured in any case of the positional deviation in the surface of the butting surface and in the normal direction, and not only a two-dimensional deviation but also a three-dimensional positional deviation can be detected.

FIG. 5A is a schematic perspective view showing a state where the case 2 and the jig 1 constituting the jig set 40 according to the first embodiment are not correctly combined. FIG. 5B is a schematic perspective view showing a state in which the case 2 and the jig 1 are combined by rotating 90 degrees from the correct position.
As shown in FIG. 5A, when the RFIC element 20 of the jig 1 and the antenna element 10 of the case 2 are separated from each other, the RFID tag is not configured, and RFID communication is impossible. Further, as shown in FIG. 5B, although the jig 1 and the case 2 are combined, the RFIC element 20 of the jig 1 and the antenna element 10 of the case 2 are not electrically connected. The RFID tag is not configured. Between the jig 1 and the case 2, there are a plurality of combination patterns in the positional relationship between the RFIC element 20 and the antenna element 10. Specifically, FIG. 1B shows a correct combination pattern of the jig 1 and the case 2. In contrast, FIG. 5B shows an example of an incorrect combination pattern of the jig 1 and the case 2. In addition to FIG. 5 (b), the jig 1 and the case 2 are rotated 180 degrees from the correct position in FIG. 1 (b) and combined (not shown), the correct in FIG. 1 (b). There is an incorrect combination pattern that is rotated 270 degrees from the position and combined (not shown). As a whole, there are four combination patterns in which the jig 1 and the case 2 can be combined. Among them, the RFIC element 20 and the antenna element 10 are in contact with each other and electrically connected to form an RFID tag in one pattern, and the RFIC element 20 and the antenna element 10 are separated from each other so that the RFID tag is not formed. There are three incorrect positions.
According to the jig set 40 according to the first embodiment, the RFID tag is configured and RFID communication can be performed only in the case of one pattern at the correct position. Therefore, it is possible to determine whether the pattern is one pattern at the correct position or the other three patterns at the incorrect position depending on whether or not RFID communication is possible. As a result, a positional deviation due to rotation can be detected.

That is, the jig 1 may have a shape having rotational symmetry. Thus, a plurality of combination patterns can be realized for the combination pattern of the jig 1 and the case 2. Specifically, the jig 1 may be square as shown in FIG. In this case, there are four possible combinations of the jig 1 and the case 2 as described above. That is, when the jig 1 is a regular polygon, it has the same combination pattern as the number of sides of the polygon. In the case of FIG. 5B, the jig 1 and the case 2 are combined by rotating 90 degrees from the correct combination pattern. That is, since the positions of the RFIC element 20 and the antenna element 10 are rotated by 90 degrees, RFID communication cannot be performed. Similarly, the jig 1 may be a regular polygon such as a hexagon or an octagon.
Note that the jig 1 is not limited to a regular polygon, and may be a rectangle, for example. Further, it may be circular or elliptical. When the shape of the jig 1 is a rectangle or an ellipse, it has two combination patterns including an original case and a case where the jig 1 is rotated 180 degrees.

FIG. 6 is a schematic cross-sectional view showing a state in which the jig 1 floats by biting the foreign material 9 between the jig 1 and the case 2 in the jig set according to the first embodiment.
In FIG. 6, the jig 1 is almost contained in the case 2, but the jig 1 slightly floats because the foreign matter 9 is bitten in the bottom of the case 2. In such a case, in the conventional displacement detection method based on image analysis, for example, even if the jig 1 is provided with a reference mark, the reference mark can be detected almost at a predetermined position in the image from above. Cannot be detected.
On the other hand, in the jig set 40 according to the first embodiment, since the jig 1 is slightly lifted from the case 2, the RFIC element 20 of the jig 1 and the antenna element 10 of the case 2 are electrically connected. The RFID tag is not configured. As a result, RFID communication cannot be performed. Therefore, according to the jig set 40 according to the first embodiment, the lifting of the jig 1 due to the foreign matter 9 caught between the jig 1 and the case 2 can also be detected.

  According to the jig set 40, since the RFIC element 20 and the antenna element 10 are separately arranged, “RFID communication is possible only when combined in a correct state at the time of manufacture”. Therefore, for example, it is possible to detect a three-dimensional positional shift such as the lifting of the jig 1 (FIGS. 5A and 6) and the wrong mounting direction of the jig 1 (FIG. 5B). In addition, by attaching an RFID reader to the facility, it may be determined whether or not the machining process can be started such that the subsequent machining is not started when RFID communication is not possible. In addition, it is possible to manage pomissoms such as mounting mistakes at the manufacturing site.

(Modification)
FIG. 7A is a schematic perspective view showing a jig set 40a including a case 2a and a cover 1a according to a modification of the first embodiment. FIG.7 (b) is a schematic perspective view which shows the state with which the jig | tool set 40a of Fig.7 (a) was combined.
The jig set 40a according to this modification is different from the jig set 40 according to the first embodiment in that the cover 1a is used as a jig. In the jig set 40a, the RFIC element 20 is provided below the cover 1a. When the cover 1a and the case 2a are combined, the RFIC element 20 of the cover 1a can be electrically connected to the antenna element 10 of the case 2a to constitute an RFID tag.

FIG. 8A is a schematic perspective view showing a state where the cover 1a and the case 2a constituting the jig set 40a according to the modification of the first embodiment are not correctly combined. FIG. 8B is a schematic perspective view showing a state where the cover 1a and the case 2a are combined by rotating 90 degrees from the correct position.
As shown in FIG. 8A, since the RFIC element 20 of the cover 1a and the antenna element 10 of the case 2a are separated from each other, an RFID tag is not configured, and RFID communication becomes impossible. Further, as shown in FIG. 8B, although the cover 1a and the case 2a are combined, the RFIC element 20 of the cover 1a and the antenna element 10 of the case 2a are rotated by 90 degrees, so that the The RFID tag is not configured.

(Embodiment 2)
<Jig set>
FIG. 9A is a plan view showing a state in which the workpiece 4 is set by the jig set 40b including the holding jig 1b and the base 2b according to the second embodiment. FIG. 9B is a schematic cross-sectional view showing a vertical positional relationship among the holding jig 1b, the pedestal 2b, and the workpiece 4. FIG.9 (c) is a schematic sectional drawing seen from the AA direction of Fig.9 (a). FIG. 10 is a schematic view showing a processing apparatus 50 including the jig set 40b of FIG. FIG. 11 is a block diagram showing a configuration of the processing apparatus 50 of FIG.
The jig set 40b is different from the jig set according to the first embodiment in that the first jig is the holding jig 1b and the second jig is not the case but the base 2b. A workpiece (collected substrate) 4 for processing is sandwiched and held between the holding jig 1b and the base 2b. The workpiece 4 is a collective substrate and has a plurality of workpieces. An RFIC element (abbreviated as “RFIC” in FIG. 11) 20 is provided on a surface of the holding jig 1b facing the pedestal 2b, and an antenna element 10 (first antenna) is provided on the surface of the pedestal 2b facing the holding jig 1b. Antenna element 11 and second antenna element 12) (abbreviated as “ANT” in FIG. 11) are provided.

When the workpiece 4 for processing can be firmly held between the holding jig 1b and the base 2b, the RFIC element 20 of the holding jig 1b and the antenna element 10 of the base 2b can be electrically connected. An RFID tag is configured and RFID communication can be performed. On the other hand, when the work 4 is not sufficiently held between the holding jig 1b and the pedestal 2b, for example, when a gap is formed between the holding jig 1b and the pedestal 2b, the holding jig 1b is used. Cause floating. For this reason, the RFIC element 20 and the antenna element 10 are not electrically connected, and no RFID tag is formed, so that RFID communication is not possible. Therefore, by determining whether RFID communication with the RFID tag is possible, it can be confirmed whether the workpiece 4 is sufficiently held between the holding jig 1b and the base 2b, for example, whether the workpiece 4 is lifted.
The workpiece 4 may be, for example, a metal mask in screen printing.

<Processing equipment>
As shown in FIGS. 10 and 11, the processing apparatus 50 including the jig set 40 b includes a laser processing machine 32 that performs laser processing by irradiating a workpiece 34 set on the jig set 40 b with a laser 34, and a reader / writer. An antenna 36, a human interface 38, and a host controller 39 are provided. The reader / writer antenna 36 performs RFID communication with the RFID tag 30 constituted by the RFIC element 20 of the holding jig 1b and the antenna element 10 of the base 2b. If RFID communication can be performed, processing is started.
Here, a reader / writer antenna is used for RFID communication with the RFID tag 30, but the present invention is not limited thereto, and any RFID reader that acquires at least identification information from the RFID tag may be used. In addition, when RFID communication with the RFID tag can be performed, RFID communication is possible because identification information can be acquired from the RFIC element.

<Processing method>
FIG. 12 is a flowchart of a processing method using the processing apparatus of FIG.
<Step 1>
(A) The work 4 is placed on the base 2b, which is the second jig, and the holding jig 1b, which is the first jig, is set (S01). An antenna element 10 is provided on the base 2b. The holding jig 1b is provided with an RFIC element 20 having first identification information. The holding jig 1b and the pedestal 2b are a jig forming a set. When the holding jig 1b and the pedestal 2b are combined at a predetermined position, the RFIC element 20 and the antenna element 10 can be electrically connected and constitute an RFID tag.
(B) It is determined whether communication is possible with an RFID tag constituted by an RFIC element and an antenna element (S02). Specifically, it is determined whether RFID communication with the RFID tag 30 formed of the RFIC element 20 and the antenna element 10 is possible. If RFID communication is possible, the first identification information of the RFIC element 20 can be acquired. In this case, it can be determined that the positional relationship between the base 2b and the pressing jig 1b is appropriate. That is, it can be determined that the workpiece 4 is sufficiently held between the holding jig 1b and the base 2b.
(C) When RFID communication with the RFID tag has been established (OK), product type information is written into the RFIC element 20 of the RFID tag for the lot (product type) of the work 4 (S03). The product type information may indicate, for example, a combination of processing steps performed on the workpiece 4. That is, in the subsequent machining process, this kind information can be read to manage the machining process for the workpiece 4.
(D) Thereafter, laser processing is started (S04). In addition, as laser processing, it is laser printing processing of each workpiece, for example. On the other hand, when the RFID communication cannot be performed (NG), for example, an alarm sounds (S05) to warn the worker. In this case, since RFID communication could not be performed, it can be seen that the holding jig 1b and the base 2b are not correctly combined. Therefore, the operator resets the workpiece 4 with the holding jig 1b and the base 2b (S06).
As described above, since the laser processing can be started after the holding of the workpiece 4 by the holding jig 1b and the pedestal 2b is ensured, the processing state of the workpiece 4 can be stabilized. If the workpiece 4 is not set properly, the machining state varies between the workpieces in the workpiece 4.

  Moreover, in the said processing method, the workpiece | work 4 is set with the holding jig 1b and the base 2b, and the processing process is performed. Therefore, when performing a plurality of processing steps as well as a single processing step, the process management can be performed by the RFID tag 30 including the RFIC element 20 and the antenna element 10 in the subsequent processing steps. . For example, the processing conditions in each process may be managed by RFID communication with an RFID tag configured.

<Process 2>
An example of process management in the case where the workpiece 4 is set by the holding jig 1b and the pedestal 2b and processing is performed in the next process 2 will be described.
(E) In step 2, it is determined whether communication with the RFID tag 30 constituted by the RFIC element 20 and the antenna element 10 is possible (S07). Thereby, also in the process 2, it can be confirmed whether or not the work 4 is fixed by the holding jig 1b and the base 2b due to movement or the like.
(F) If RFID communication with the RFID tag 30 has been established, processing in step 2 is started (S08).
(G) If RFID communication is not possible, it is considered that the work 4 is not sufficiently fixed by the holding jig 1b and the pedestal 2b. For example, an alarm sounds (S09) to warn the operator. Thereafter, the operator resets the workpiece 4 (S10).

<Jig set>
FIG. 13A is a plan view showing a state in which the workpiece 4 is set by the jig set 40c including the holding jig 1c and the base 2c according to the third embodiment. FIG. 13B is a schematic cross-sectional view seen from the BB direction of FIG. FIG. 14 is a block diagram showing a configuration of the processing apparatus 50 including the jig set 40c of FIG.
This jig set 40c is different from the jig set 40b according to the second embodiment in that RFIC elements 20a, 20b, 20c, and 20d are provided on four sides of the holding jig 1c, respectively. Another difference is that antenna elements 10a, 10b, 10c, and 10d are provided on the four sides of the base 2c, respectively. The RFIC elements 20a, 20b, 20c, and 20d on each side and the antenna elements 10a, 10b, 10c, and 10d are arranged corresponding to each other. When the workpiece 4 is lifted on any of the four sides, the presser jig 1c is also lifted. In this case, since the RFIC element and the antenna element on the side where the float has occurred are not electrically connected, the RFID tag is not configured. As a result, whether or not the four sides are lifted can be confirmed by checking whether the RFID communication with all the RFID tags on the four sides has been completed.

  In FIG. 13A, the arrangement positions of the RFIC elements 20a, 20b, 20c, and 20d and the antenna elements 10a, 10b, 10c, and 10d are approximately the center of each side, and the same positions are provided on the four sides. For this reason, in order to detect misalignment due to rotation, an RFIC element and an antenna element are provided only on one side as shown in FIG. 1 (a) and FIG. 5 (a) instead of all four sides, or You may provide in 2 sides or 3 sides. Further, the RFIC element and the antenna element may be arranged at different positions on each side. By disposing the RFIC elements 20a, 20b, 20c, and 20d and the antenna elements 10a, 10b, and the antenna elements 10a, 10b, when the position is shifted from the correct position among a plurality of possible combination patterns by disposing them at different positions on each side. The positions of 10c and 10d are deviated, and the RFID tag can be configured only by the combination that should originally correspond. By these, it is possible to detect a positional shift due to rotation.

<Processing equipment>
As shown in FIG. 14, the processing apparatus 50a including the jig set 40c includes a processing tool 37 for processing the workpiece 4 set in the jig set 40c, a reader / writer antenna 36, a human interface 38, and a host controller 39. And comprising.
In contrast to the processing device 50 according to the second embodiment, the processing device 50a is provided with four sets of RFIC elements (abbreviated as “RFIC” in FIG. 14) provided on the four sides of the jig set 40c by the reader / writer antenna 36. 20a, 20b, 20c, 20d and antenna elements (abbreviated as “ANT” in FIG. 14) 10a, 10b, 10c, and 10d are different from each other in that RFID communication is performed. To do. If RFID communication can be performed with all of the RFID tags configured on each side, it can be confirmed that the four sides are correctly arranged. That is, if RFID communication can be performed with all the RFID tags on the four sides, the positional relationship between the pedestal 2c and the pressing jig 1c can be determined to be appropriate, and processing can be started.

That is, when the workpiece 4 for processing can be firmly held between the holding jig 1c and the base 2c, the RFIC elements 20a, 20b, 20c, 20d of the holding jig 1c and the antenna element 10a of the base 2c, 10b, 10c, and 10d can be electrically connected to each other, configure an RFID tag, and perform RFID communication. On the other hand, when the periphery of the workpiece 4 is not sufficiently pressed by the holding jig 1c, for example, when there is a gap between the holding jig 1c and the base 2c, the holding jig 1c is lifted. Arise. For this reason, at least one of the RFIC elements 20a, 20b, 20c, and 20d is not electrically connected to at least one of the antenna elements 10a, 10b, 10c, and 10d, and the RFID tag is not configured, so that RFID communication cannot be performed. Therefore, by determining whether RFID communication with all RFID tags is possible, it is possible to confirm whether the periphery of the work 4 is sufficiently pressed by the holding jig 1c. Thereby, for example, it can be confirmed whether or not the workpiece 4 is lifted.
If even one of the four RFID tags cannot perform RFID communication, it is determined that the positional relationship between the base 2c and the holding jig 1c is inappropriate, that is, the work 4 is not sufficiently pressed by the holding jig 1c. To do.

<Processing method>
FIG. 15 is a flowchart of a processing method using the processing apparatus of FIG.
(A) The work 4 is placed on the base 2c as the second jig, and the holding jig 1c as the first jig is set (S11). The pedestal 2c is provided with antenna elements 10a, 10b, 10c, and 10d on four sides, respectively. The holding jig 1c is provided with RFIC elements 20a, 20b, 20c, and 20d having different identification information. The holding jig 1c and the pedestal 2c are a jig forming a set. When the holding jig 1c and the base 2c are combined at a predetermined position, the RFIC elements 20a, 20b, 20c, and 20d and the antenna elements 10a, 10b, 10c, and 10d can be electrically connected to each other, Each constitutes an RFID tag.
(B) It is determined whether communication is possible with all RFID tags configured by the RFIC element and the antenna element (S12). Specifically, it is determined whether RFID communication is possible with four sets of RFID tags including the RFIC elements 20a, 20b, 20c, and 20d and the antenna elements 10a, 10b, 10c, and 10d. If RFID communication is possible, identification information of the RFIC elements 20a, 20b, 20c, and 20d can be acquired. In this case, it can be determined that the positional relationship between the base 2c and the holding jig 1c is appropriate. That is, it can be determined that the workpiece 4 is sufficiently held between the holding jig 1c and the base 2c.
(C) When RFID communication with all the RFID tags has been completed (OK), laser processing is started (S13). On the other hand, when the RFID communication cannot be performed (NG), for example, an alarm sounds (S14) to warn the worker. In this case, since RFID communication could not be performed, it can be seen that the holding jig 1c and the base 2c are not correctly combined. Therefore, the worker resets the workpiece 4 (S15).
As described above, since the laser machining can be started after the holding of the workpiece 4 by the holding jig 1c and the base 2c is ensured, the machining state of the workpiece 4 can be stabilized.

(Embodiment 4)
<Jig set>
FIG. 16A is a schematic cross-sectional view showing the positional relationship in the vertical direction of a jig set 40d composed of the upper mold 1d and the lower mold 2d according to the fourth embodiment. FIG. 16B is a schematic cross-sectional view showing a state in which the upper mold 1d and the lower mold 2d in FIG. FIG. 17 is a block diagram showing a configuration of an injection molding apparatus 50b including the jig set 40d of FIG.
This jig set 40d is different from the jig set according to the second embodiment in that the first jig is the upper mold 1d and the second jig is not the case but the lower mold 2d. To do. Further, not only the combination of the RFIC element 20e and the antenna element 10e but also another set of the RFIC element 20f and the antenna element 10f is different in that the first jig 1d and the second jig 2d are replaced. . That is, the upper mold 1d is provided with the RFIC element 20e and the antenna element 10f. The lower mold 2d is provided with an antenna element 10e and an RFIC element 20f.

  In this jig set 40d, an RFID tag comprising a combination of the RFIC element 20e of the upper mold 1d and the antenna element 10e of the lower mold 2d, the antenna element 10f of the upper mold 1d, and the RFIC element 20f of the lower mold 2d The RFID tag can be configured by a combination of the above. In this case, even if the combination of the upper mold 1d and the lower mold 2d is rotated by 180 °, the RFIC elements 20e and 20f and the antenna elements 10e and 10f face each other, and the RFID tag is not configured. That is, by determining whether RFID communication with two RFID tags is possible, it is possible to confirm whether or not the combination position of the upper mold 1d and the lower mold 2d is correct.

<Processing equipment>
As shown in FIG. 17, a processing apparatus 50b including a jig set 40d includes a processing tool 37 for injecting resin into a space 6 between an upper mold 1d and a lower mold 2d, which are the jig set 40d, A reader / writer antenna 36, a human interface 38, and a host controller 39 are provided.
Compared with the processing device 50 according to the second embodiment, the processing device 50b includes an RFID tag formed by a combination of the RFIC element 20e of the upper mold 1d and the antenna element 10e of the lower mold 2d by the reader / writer antenna 36. The RFID tag is different from the RFID tag formed by a combination of the antenna element 10f of the upper mold 1d and the RFIC element 20f of the lower mold 2d in that RFID communication is performed. By performing RFID communication with the two RFID tags, it can be confirmed whether or not the combination position of the upper mold 1d and the lower mold 2d is correct.

In the injection molding, the upper mold 1d and the lower mold 2d are combined, and the resin heated from the processing tool 37 to the softening temperature is pushed into the space 6 with a predetermined pressure. At this time, if the upper mold 1d and the lower mold 2d are not set correctly, the resin may leak or the target shape may not be obtained.
Further, when there are a plurality of upper molds and a plurality of lower molds, a desired molded product cannot be obtained if the combination of the upper mold 1d and the lower mold 2d is mistaken.

  First, according to this processing apparatus 50b, if RFID communication can be performed with two RFID tags, it can be determined that the positional relationship between the upper mold 1d and the lower mold 2d is appropriate.

That is, when the upper mold 1d and the lower mold 2d can be properly set, the RFIC element 20e of the upper mold 1d, the antenna element 10e of the lower mold 2d, and the RFIC element of the lower mold 2d 20f and the antenna element 10f of the upper mold 1d can be electrically connected to each other to form an RFID tag and perform RFID communication. On the other hand, when the upper mold 1d and the lower mold 2d are not set at the correct positions, at least one of the RFIC elements 20e and 20f and at least one of the antenna elements 10e and 10f are not electrically connected, RFID communication is not possible because the RFID tag is not configured. Therefore, by determining whether RFID communication is possible with all RFID tags, it is confirmed whether the upper mold 1d and the lower mold 2d can be set at the correct positions, for example, whether the upper mold 1d is lifted. it can.
If even one of the two RFID tags cannot perform RFID communication, it is determined that the positional relationship between the upper mold 1d and the lower mold 2d is inappropriate, for example, the upper mold 1d is floating.

  Next, it is determined whether or not the combination of the upper mold 1d and the lower mold 2d is a correct combination. Specifically, the upper mold 1d is provided with an RFIC element 20e having first identification information related to the upper mold 1d, and the lower mold 2d is provided with an RFIC element 20f having second identification information related to the lower mold 2d. Is provided. The first identification information of the RFIC element 20e is acquired by RFID communication with the RFID tag by the combination of the RFIC element 20e of the upper mold 1d and the antenna element 10e of the lower mold 2d. Further, the second identification information of the RFIC element 20f is acquired by RFID communication with the RFID tag by the combination of the antenna element 10f of the upper mold 1d and the RFIC element 20f of the lower mold 2d. By checking whether the combination of the first identification information and the second identification information is the same as the combination of the first identification information of the upper mold and the second identification information of the lower mold that are set in advance. It can be determined whether or not the combination of the upper mold 1d and the lower mold 2d is a correct combination.

The lower mold 2d is provided with an antenna element 10e and an RFIC element 20f. When the upper mold 1d and the lower mold 2d are combined at a predetermined position, the RFIC element 20e of the upper mold 1d and the antenna element 10e of the lower mold 2d can be electrically connected to constitute an RFID tag. . Further, the antenna element 10f of the upper mold 1d and the RFIC element 20f of the lower mold 2d can be electrically connected to constitute an RFID tag.
(B) It is determined whether RFID communication can be performed with two RFID tags configured when the upper mold 1d and the lower mold 2d are combined at a predetermined position (S22). Specifically, an RFID tag formed by a combination of the RFIC element 20e of the upper mold 1d and the antenna element 10e of the lower mold 2d, and a combination of the antenna element 10f of the upper mold 1d and the RFIC element 20f of the lower mold 2d. It is determined whether the RFID tag can communicate with the RFID tag, and the first identification information of the RFIC element 20e and the second identification information of the RFIC element 20f are acquired. When RFID communication cannot be performed with at least one RFID tag (NG), it is determined that the alignment between the upper mold 1d and the lower mold 2d is inappropriate. In this case, since RFID communication could not be performed, it can be seen that the upper mold 1d and the lower mold 2d are not set at the correct positions. Here, the inappropriate alignment means, for example, a case where the upper mold 1d is lifted from a correct position. In this case, a misalignment alarm is issued to warn the operator (S25). Thereafter, the operator aligns and resets the same upper mold 1d and lower mold 2d (S26). And it returns to the step (S22) which judges whether RFID communication with two RFID tags comprised when the upper metal mold | die 1d and the lower metal mold | die 2d are combined in a predetermined position is possible.

(C) Next, it is determined whether the combination of the upper mold 1d and the lower mold 2d is a correct combination (S23). That is, it is determined whether the combination of the first identification information regarding the upper mold 1d and the second identification information regarding the lower mold 2d is a correct combination. The combination of the two molds 1d and 2d is determined by combining the first identification information and the second identification information with the first identification information of the upper mold to be used and the second identification of the lower mold. This can be done by checking whether the information combination is the same.
(D) When it is determined that the combination of the upper mold 1d and the lower mold 2d is a correct combination, machining is started (S24). On the other hand, if the combination of the upper mold 1d and the lower mold 2d is wrong, an alarm of a combination failure is issued to warn the operator (S27). The operator confirms the mold type again and resets the combination with the correct combination of the upper mold 1d and the lower mold 2d (S28). And it returns to the step (S22) which judges whether RFID communication with two RFID tags comprised when the upper metal mold | die 1d and the lower metal mold | die 2d are combined in a predetermined position is possible.
As described above, an appropriate combination of the upper mold 1d and the lower mold 2d can be set at the correct position for injection molding.
Here, the processing is started when it is determined that the combination of the upper mold 1d and the lower mold 2d is a correct combination. However, the present invention is not limited to this, and similarly to the third embodiment, 2 You may set so that a process may be started when it can communicate with one RFID tag.

<Jig set>
FIG. 19A is a schematic cross-sectional view showing the positional relationship in the vertical direction of a jig set 40e composed of the upper mold 1e and the lower mold 2e according to the fifth embodiment. FIG. 19B is a schematic cross-sectional view showing a state in which the upper mold 1e and the lower mold 2e in FIG. 19A are combined.
The jig set 40e is different from the jig set 40d according to the fourth embodiment in that the upper mold 1e and the lower mold 2e are conductive, for example, metal molds. Therefore, auxiliary portions 8a, 8b, 8c, and 8d made of a material that has little influence on radio waves, such as resin, are provided integrally with the upper mold 1e and the lower mold 2e. That is, the upper mold 1e and the auxiliary portions 8a and 8c provided integrally therewith can be regarded as constituting the upper mold 1e as a whole. Similarly, the lower mold 2e and the auxiliary portions 8b and 8d provided integrally therewith can be regarded as constituting the lower mold 2e as a whole.
In FIG. 19B, auxiliary parts 8a and 8c are provided on the upper mold 1e, and auxiliary parts 8b and 8d are provided on the lower mold 2e. Among these, the auxiliary part 8a and the auxiliary part 8b face each other, and the auxiliary part 8c and the auxiliary part 8d face each other. Further, the RFIC elements 20g and 20h and the antenna elements 10g and 10h are not the upper mold 1e and the lower mold 2e itself, but the auxiliary portions 8a and 8b provided integrally with the upper mold 1e and the lower mold 2e. , 8c and 8d, respectively. Specifically, the RFIC element 20g is provided in the auxiliary unit 8a, the antenna element 10g is provided in the auxiliary unit 8b, the antenna element 10h is provided in the auxiliary unit 8c, and the RFIC element 20h is provided in the auxiliary unit 8d. .
Thus, when the upper mold 1e and the lower mold 2e are combined, the RFIC element 20g and the antenna element 10g can be electrically connected to each other, and the RFIC element 20h and the antenna element 10h can be electrically connected to each other. Connection is possible. In this case, the influence of the metal upper mold 1e and the lower mold 2e, for example, the influence of shielding by the metal upper mold 1e and the lower mold 2e, and the influence of high heat during injection molding are reduced. Thus, the RFID communication can be performed while suppressing the deterioration of the communication distance.

<Processing method>
FIG. 20 is a flowchart of a processing method using a processing apparatus including the jig set 40e of FIG.
(A) The upper mold 1e as the first jig and the lower mold 2e as the second jig are set in combination (S31). The auxiliary portions 8a and 8c provided integrally with the upper mold 1e are provided with an RFIC element 20g and an antenna element 10h, respectively. The auxiliary portions 8b and 8d provided integrally with the lower mold 2e are provided with an antenna element 10g and an RFIC element 20h, respectively. When the upper mold 1e and the lower mold 2e are combined at a predetermined position, the RFIC element 20g of the auxiliary unit 8a and the antenna element 10g of the auxiliary unit 8b can be electrically connected to constitute an RFID tag. In addition, the antenna element 10h of the auxiliary unit 8c and the RFIC element 20h of the auxiliary unit 8d can be electrically connected to constitute an RFID tag.
(B) It is determined whether RFID communication can be performed with two RFID tags configured when the upper mold 1e and the lower mold 2e are combined at a predetermined position (S32). Specifically, the RFID tag is a combination of the RFIC element 20g of the auxiliary unit 8a and the antenna element 10g of the auxiliary unit 8b, and the RFID tag is a combination of the antenna element 10h of the auxiliary unit 8c and the RFIC element 20h of the auxiliary unit 8d. Then, it is determined whether RFID communication is possible, and the first identification information of the RFIC element 20g and the second identification information of the RFIC element 20h are acquired. When RFID communication cannot be performed with at least one RFID tag (NG), it is determined that the upper mold 1e and the lower mold 2e are not properly aligned. In this case, since RFID communication could not be performed, it can be seen that the upper mold 1e and the lower mold 2e are not set at the correct positions. Here, inadequate alignment means, for example, the case where the upper mold 1e is floating from the correct position. In this case, a misalignment alarm is issued to warn the operator (S36). Thereafter, the operator aligns and resets the same upper mold 1e and lower mold 2e (S37). And it returns to the step (S32) which judges whether RFID communication with two RFID tags comprised when the upper metal mold | die 1e and the lower metal mold | die 2e are combined in a predetermined position is possible.

(C) Next, it is determined whether the combination of the upper mold 1e and the lower mold 2e is a correct combination (S33). That is, it is determined whether the combination of the first identification information regarding the upper mold 1e and the second identification information regarding the lower mold 2e is a correct combination. The combination of the two molds 1e and 2e is determined by combining the first identification information and the second identification information with the first identification information of the upper mold to be used and the second identification of the lower mold. This can be done by checking whether the information combination is the same.
(D) When it is determined that the combination of the upper mold 1e and the lower mold 2e is a correct combination, the first identification information is based on the first identification information and the second identification information that each mold has. Then, the combination of the second identification information and the machining condition associated in advance are selected, and the first and second identification information of each mold and the machining condition are associated (S34).
(E) Thereafter, machining is started according to the tied machining conditions (S35).
(F) On the other hand, if the combination of the upper mold 1e and the lower mold 2e is incorrect, an alarm of a defective combination is issued to warn the operator (S38). The operator checks the mold type again and resets the combination with the correct upper mold 1e and lower mold 2e (S39). Thereafter, the process returns to the step of determining whether or not RFID communication can be performed with the two RFID tags configured when the upper mold 1e and the lower mold 2e are combined at a predetermined position (S32).
As described above, an appropriate combination of the upper mold 1e and the lower mold 2e can be set at a correct position for injection molding. Moreover, it can process according to the process conditions matched based on the combination of the upper metal mold | die 1e and the lower metal mold | die 2e.
Here, the processing is started when it is determined that the combination of the upper mold 1e and the lower mold 2e is a correct combination.
