The table portion 47 is formed with two member mounting tables 47a and 47b that extend upward. As shown in Fig. 3, a suction pipe 49 is attached to the table portion 47. The suction pipe 49 is connected to the tops of the component mounting tables 47a, 47b via through holes formed in the land portion 47. The suction device (not shown) suctions the suction pipe 49, whereby a negative pressure is generated at the top of the component mounting tables 47a and 47b, and the light-emitting element L is attracted.

A flat cylindrical follower 45a whose central axis is oriented in the front-rear direction is formed at the lower end portion of the foot portion 45. The driven wheel 45a comes into contact with the control lever 67 of the elevating mechanism 6 to be described later, and transmits the force received from the control lever 67 to the movable portion 44. The traction spring 46 pulls the movable portion 44 downward. When the movable portion 44 receives the force from the driven wheel 45a, it is slid upward against the traction force of the traction spring 46.

Fig. 5 is a side view of the elevating mechanism 6. The elevating mechanism 6 is disposed beside the second intermittent rotating disk 4, and is used to raise and lower the component mounting tables 47a and 47b of the component conveying portion 42.

The fixing portion 65 is fixed to the wall portion 61; the support portion 68 is disposed between the cylinder 62 and the member conveying portion 42; the control lever 67 is rotatably supported by the upper end portion of the support portion 68; and the traction spring 66 is erected between the fixing portion 65 and the control rod 67.

The cylinder 62 moves the shaft portion 63 forward and backward in the vertical direction. The front end portion 64 of the shaft portion 63 is rotatably attached to the force point portion 67b provided at one end portion of the control lever 67. The acting portion 67c provided at the other end of the lever 67 is in contact with the lower surface of the driven wheel 45a provided at the lower end of the member carrying portion 42. The traction spring 66 is stretched over the protrusion portion 67a of the fixing portion 65 and the protrusion portion 67d on the side of the force point portion 67b of the control lever 67, and pulls the force point portion 67b side of the control lever 67 upward.

When the cylinder 62 pushes the shaft portion 63 downward, the action portion 67c side of the control lever 67 is pushed upward against the traction force of the traction spring 66. At this time, since the acting portion 67c of the control lever 67 pushes up the driven wheel 45a of the member conveying portion 42, the member mounting tables 47a and 47b are raised. While the member conveying portion 42 is located below the head portion 51, the cylinder 62 reciprocates the shaft portion 63 once. When the shaft portion 63 is pressed downward, the member mounting tables 47a and 47b rise to the position of the head portion 51, and then return to the initial position when the shaft portion 63 returns upward.

6A and 6B are cross-sectional views of the head 51. The head portion 51 is provided with a plurality of adsorption nozzles 58 attached to the distal end of the suction tube 59, a flat plate portion 512 for supporting the adsorption nozzles 58, and a heart-shaped lid portion 513 disposed on the upper surface side of the flat plate portion 512. And covering the upper portion of the adsorption nozzle 58; the frame portion 515 and the light transmitting portion 516 are disposed on the lower surface side of the flat plate portion 512 and surround the lower portion of the adsorption nozzle 58; and are connected to the flat plate portion by the sensors 514a, 514b. The lower surface side of the 512 is disposed so as to sandwich members such as the frame portion 515 and the light transmitting portion 516. In this embodiment, the head 51 has Two adsorption nozzles 58.

The adsorption nozzle 58 is formed in a cylindrical shape having a flange, and is inserted into a through hole formed in the flat plate portion 512 from above. As shown in FIG. 7, the adsorption nozzle 58 has a cylindrical tubular portion 581 and a flange portion 583 having a larger diameter than the cylindrical portion 581. The adsorption nozzle 58 is formed with an insertion hole 58a, a through hole 58b, and an insertion hole 58c which are continuous in the axial direction. The lens portion Lp that protrudes in a convex shape of the light-emitting element L is inserted into the insertion hole 58a formed at the front end portion of the tubular portion 581. The front end portion of the suction tube 59 is inserted into the insertion hole 58c formed in the flange portion 583. The insertion holes 58a, 58c are connected by a through hole 58b having a smaller diameter than them.

The lid portion 513 is disposed to surround the two adsorption nozzles 58, and the suction tube 59 extends from a hole formed in the top of the lid portion 513. In the inner space of the lid portion 513, a compression spring 517 as a cushioning member is disposed so as to be wound around the front end portion of the suction tube 59. When the upper impact acts on the adsorption nozzle 58, as the adsorption nozzle 58 rises, the compression spring 517 is compressed, and the impact is absorbed.

The frame portion 515 surrounds the space below each of the adsorption nozzles 58 in the horizontal direction, thereby forming concave portions 515a, 515b that open downward. The member mounting tables 47a and 47b are respectively inserted into the concave portions 515a and 515b from the lower side. The light transmitting portion 516 is disposed between the passing sensors 514a, 514b.

The pass sensors 514a, 514b are photo interrupters, one of which passes through the sensor is a light emitting portion and the other through which the sensor is a light receiving portion. Light emitted from one of the sensors 514a, 514b through the sensor penetrates the light transmitting portion 516, passes through the lower side of the adsorption nozzle 58, and finally reaches the other passing sensor. Thereby, the falling of the light-emitting element L adsorbed by the adsorption nozzle 58 can be detected.

The member mounting tables 47a and 47b are raised by the operation of the elevating mechanism 6, and are inserted into the concave portions 515a and 515b of the head portion 51, respectively. The member mounting tables 47a, 47b inserted into the concave portions 515a, 515b pass between the passing sensors 514a, 514b and then reach the lower end of the adsorption nozzle 58. At this time, the light-emitting elements L placed on the member mounting bases 47a and 47b are collectively adsorbed by the adsorption nozzles 58.

Further, the head portion 51 is not limited to the above-described aspect, and may be the one shown in FIGS. 13A and 13B. In this aspect, the adsorption nozzle 58 is moved up and down by the operation of the elevating mechanism (not shown). The adsorption nozzles 58 pass through between the passing sensors 514a, 514b and then descend to reach the upper ends of the member mounting tables 47a, 47b located below the recesses 515a, 515b. At this time, the light-emitting elements L placed on the member mounting bases 47a and 47b are adsorbed by the adsorption nozzles 58 in unison.

Fig. 8 is a schematic view showing the structure of adsorption. The suction pipe 59 attached to the adsorption nozzle 58 is divided into two pipes in the middle, one of which is provided with a gas suction portion 71 for sucking the gas in the pipe, and the other pipe is provided with a gas injection portion 74 for injecting gas into the pipe. Further, a barometric pressure sensor 77 for detecting the air pressure in the pipe is provided in the middle of the suction pipe 59. The gas suction portion 71 has a suction device 72 that is a suction gas, and a solenoid valve 73 that is disposed at a line that reaches the suction device 72. The solenoid valve 73 adjusts the amount of suction of the gas. On the other hand, the gas injection unit 74 includes a discharge unit 75 that discharges gas, and a solenoid valve 76 that is disposed in a line that reaches the discharge unit. The solenoid valve 76 adjusts the amount of gas injected.

Fig. 9 is a block diagram of the sorting device 1 for electronic components. The main control unit 10 is connected to the characteristic measuring unit 12, the sensors 514a and 514b, the air pressure sensor 77, the positioning unit 5, the elevating mechanism 6, and the electromagnetic valves 73 and 76. Further, the main control unit 10 functionally includes a container selecting unit 14. In addition, the main control unit 10 controls the first intermittent rotating disk 2, the second intermittent rotating disk 4, the component feeder 3, the component transfer machines 34 and 39, and the position adjusting machine 36 shown in Fig. 1 described above. 37 and so on.

The main control unit 10 is configured as a computer or a PLC (programmable logic controller) including a CPU (Central Processing Unit) and a RAM (Random Access Memory) belonging to the work area. Further, the main control unit 10 includes a memory device that stores programs and data necessary for the CPU to operate.

The characteristic measuring unit 12 energizes the light-emitting element L of the component mounting table 22 placed on the first intermittent rotating disk 2 shown in the above-described first embodiment, and receives the light emitted from the light-emitting element L using the integrating sphere 12a, and supplies the light to the main control unit. 10 outputs a signal indicating the light-emitting characteristics of the light-emitting element L.

The container selecting unit 14 determines the container B that houses the light-emitting element L from the plurality of containers B based on the light-emitting characteristics obtained from the characteristic measuring unit 12. Specifically, the container selecting unit 14 determines which of the plurality of predetermined levels is to be determined by the light-emitting characteristics of the light-emitting element L. The number of levels is the same as the number of containers B, for example 128. The container selection unit 14 refers to a list of memory devices stored in the main control unit 10, and determines the container B in which the light-emitting elements L are housed based on the determined level. As shown in Fig. 11, in the list, the "level" of the light-emitting characteristics is assigned to the "container position" of each container B.

FIG. 10 is a flowchart showing a process performed by the main control unit 10 regarding the conveyance of the light-emitting element L by the positioning unit 5. First, the main control unit 10 drives the elevating mechanism 6 shown in Fig. 5 to raise the member mounting tables 47a and 47b on which the light-emitting elements L are placed (S1). This processing is performed while the intermittently rotating second intermittent rotating disk 4 is stopped. The raised member mounting tables 47a and 47b are inserted into the concave portions 515a and 515b of the head portion 51 shown in Figs. 6A and 6B. At this time, the main control unit 10 simultaneously opens the electromagnetic valves 73 of the two gas suction portions 71 corresponding to the two adsorption nozzles 58 (S2). Thus, the light-emitting element L is adsorbed by the two adsorption nozzles 58 in unison. Whether or not the light-emitting element L is adsorbed is determined based on the detection signal of the air pressure sensor 77 shown in Fig. 7 described above.

Next, the main control unit 10 drives the positioning unit 5 to transport the light-emitting element L adsorbed by the first adsorption nozzle 58 to the upper side of the container B determined for the light-emitting element L (S3). The main control unit 10 specifies the position of the container B accommodating the light-emitting element L in accordance with the coordinates of the rotation angles of the two motors included in the drive unit 54 of the positioning unit 5. When the first adsorption nozzle 58 is positioned above the container B, the main control portion 10 closes the solenoid valve 73 of the first gas suction portion 71 corresponding to the first adsorption nozzle 58 (S4). Further, the main control unit 10 opens the electromagnetic valve 73 of the first gas injection unit 74 corresponding to the first adsorption nozzle 58 (S5). The order of S4 and S5 can also be reversed. In this way, since the air pressure of the suction pipe 59 connected to the first adsorption nozzle 58 becomes equal to or higher than atmospheric pressure, the light-emitting element L adsorbed by the first adsorption nozzle 58 is dropped and stored in the container B. In the present embodiment, since the falling of the light-emitting element L is close to the free fall, damage of the light-emitting element L can be suppressed. Then, when the main control unit 10 confirms that the light-emitting element L adsorbed by the first adsorption nozzle 58 has fallen (S6: YES), the solenoid valve 73 of the first gas injection portion 74 corresponding to the first adsorption nozzle 58 is closed (S7). . Whether or not the light-emitting element L has fallen is determined based on the detection signals of the sensors 514a, 514b shown in Figs. 6A and 6B.

Then, the main control unit 10 drives the positioning unit 5 to transport the light-emitting element L adsorbed by the second adsorption nozzle 58 to the upper side of the container B determined for the light-emitting element L (S8). As shown in Fig. 12, the head portion 51 of the positioning portion 5 is not returned to the initial position (i.e., above the second intermittent rotary disk 4) from the position of the container B in which the first adsorption nozzle 58 is positioned in the above S3, and It moves directly to the position of the container B which accommodates the light-emitting element L adsorbed by the 2nd adsorption nozzle 58. Therefore, in the present embodiment, the moving distance of the head portion 51 can be shortened. When the second adsorption nozzle 58 is positioned above the container B, the main control unit 10 drops the light-emitting element L adsorbed by the second adsorption nozzle 58 as in the case of the first adsorption nozzle 58. That is, the main control unit 10 closes the electromagnetic valve 73 of the second gas suction portion 71 corresponding to the second adsorption nozzle 58 (S9). Further, the main control unit 10 opens the electromagnetic valve 73 of the second gas injection unit 74 corresponding to the second adsorption nozzle 58 (S10). Then, when the main control unit 10 confirms that the light-emitting element L adsorbed by the second adsorption nozzle 58 has fallen (S11: YES), the solenoid valve 73 of the second gas injection portion 74 corresponding to the second adsorption nozzle 58 is closed (S12). .

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can of course be made by those skilled in the art.

In the above embodiment, the head portion 51 having the two adsorption nozzles 58 is exemplified. However, the present invention is not limited thereto, and the number of the adsorption nozzles 58 may be three or more.

The above embodiment is suitable for suppressing breakage of the light-emitting element L using a material having high brittleness such as ceramics. However, the object of measurement and classification is not limited thereto.

In the above-described embodiment, the light-emitting element L is used as an example of measurement and classification. However, the light-emitting element L is not limited thereto, and may be another electronic component such as a transistor or a capacitor.
