In this way, the trays 6 in the empty tray stock portion 51 are taken one by one from the top, the body 1 and the chips 2 are mounted on the tray 6, and the trays 6 on which the bodies 1 and the chips 2 are mounted.
Are stacked on the mounted tray stock portion 52.

Then, when a predetermined number of trays 6 are stacked on the mounted tray stock portion 52, these trays 6 are carried out to the next step by the carrying tool. That is, the body 1 and the chips 2 are sintered in the sintering furnace while being placed on the tray 6. During this sintering, the body 1
And the tip 2 does not directly contact the carbon tray 6, but the flange 3 of the body 1 contacts the ceramic ring 9 fitted in the tray 6, so that the body 1 or the chip 2 reacts with the carbon of the tray 6. Is prevented.

Next, the transfer and mounting of the body 1 in the first standby position and the chip 2 in the second standby position on the tray 6 will be described. The body 1 and the chips 2 are transported and mounted alternately for each of the rows of the mounting holes 7 of the tray 6 arranged side by side. That is, the mounting hole 7
Multiple rows lined up on the left and right of the
Counting as rows, ..., 15th row, first, the bodies 1 are simultaneously mounted in the mounting holes 7 of the first row, and then, on the respective bodies 1 mounted in the mounting holes 7 of the first row. Chips 2 are mounted respectively. Then, the same transportation and mounting are sequentially repeated from the second row to the fifteenth row. In addition, the number of the mounting holes 7 arranged side by side is 4, 7,
There are seven types, 9, 10, 11, 12, and 13, but when transporting and mounting the body 1 and chip 2 in the mounting holes 7 of a certain row,
Only the same number of bodies 1 and chips 2 as the mounting holes 7 in that row are conveyed and mounted.

When carrying the body 1, the pantograph 11
As 4 closes, the front and rear sliders 86 move forward, and the vacuum adsorbers 118a, ..., 118m move to the body belt conveyor.
Located on the row of bodies 1 in the first waiting position to the right of 16. At this time, the vacuum adsorber 118m at the right end is located above the body 1 at the right end. Also, pantograph 11
The pitch of the vacuum adsorbers 118a, ..., 118m when the 4 is closed is such that the body 1 closely aligned in the first standby position.
Equal to the pitch of each vacuum adsorber 118a,
, 118m are respectively located above the body 1 from the 1st to the 13th from the right. After that, the elevating body 93 is lowered by the drive of the motor 94, and each vacuum adsorber 118a, ...,
118m touches the upper surface of each body 1. Then, a predetermined one of the vacuum adsorbers 118a, ..., 118m is in a negative pressure state, and the predetermined body 1 is adsorbed. That is, when transporting the four bodies 1, the four vacuum adsorbers 118e,
118f, 118g, 118h are in a negative pressure state, and seven bodies 1
7 vacuum adsorbents 118d, ..., 118j
Is in a negative pressure state, and when the nine bodies 1 are transferred, the nine vacuum adsorbers 118c, ..., 118k are in a negative pressure state, and when the ten bodies 1 are transferred, 10 vacuum adsorptions are performed. When the eleven vacuum adsorbents 118b, ..., 118k are in a negative pressure state and the eleven bodies 1 are transported, the eleven vacuum adsorbents 118b ,.
When 118l is in a negative pressure state and 12 bodies 1 are conveyed, 12 vacuum adsorbers 118a, ..., 118l are in a negative pressure state, and when 13 bodies 1 are conveyed, 13 vacuums are conveyed. The adsorbents 118a, ..., 118m are in a negative pressure state. Then, after the elevating body 93 is raised, the front and rear sliders are retracted, and the row of the vacuum adsorbers 118a, ..., 118m is located above the row of the mounting holes 7 in the tray 6 to which the body 1 is to be mounted. During the retreat, the pantograph 114 is driven by the motor 110.
When the air cylinder device is opened, the suction base retainer 117 is lowered by the drive of the air cylinder device 116 and engages with the upper end of the suction base 113. As a result, the vacuum adsorbers 118a, ..., 118m are opened at equal intervals, and the pitch thereof is the mounting holes 7 of the tray 6.
Match the pitch of the sure and exact. Further, the arrangement of the mounting holes 7 in the tray 5 is shifted by half the pitch of the mounting holes 7 between the odd-numbered row and the even-numbered row, but when mounting in the odd-numbered row having the even-numbered mounting holes 7, By driving the motor 101, the left and right sliders 97 are moved to the right by half the pitch, while the left and right sliders 97 are not moved when the odd-numbered mounting holes 7 are mounted in the even-numbered row. This allows
Each of the bodies 1 adsorbed by the predetermined vacuum adsorbers 118a, ..., 118m is located above an empty mounting hole 7 in which the body 1 is to be mounted.

Next, after the elevating body 93 descends, the elevating table 128 rises by driving the air cylinder 131, and the pins 133 thereof are inserted through the through holes 134 of the table 13 and the mounting holes 7 of the tray 6, respectively. Vacuum adsorber 118a,
..., inserted from below into each body 1 including the one adsorbed at 118 m. By inserting this pin 133, each body 1 is corrected even if there is a positional deviation up to that point, and is positioned exactly coaxial with each mounting hole 7 of the tray 6. Then, after the adsorption by the vacuum adsorbers 118a, ..., 118m is released, the elevating table 128 descends, and its pins 133 come out of the through holes 134 of the table 13 and the respective mounting holes 7 of the tray 6. As the pins 133 descend,
Each body 1 also descends and is inserted into each mounting hole 7 of the tray 6. At this time, the insertion is surely performed by aligning the body 1 and the mounting hole 7 with the pin 133. In this way, the body 1 is transferred from the first standby position to the tray 6. As is clear from the above description, the body 1 at the first standby position is not conveyed from the right end of the row, but the body 1 at the right end.
Are transported for the first time when 12 or 13 bodies 1 are transported.

After that, after the elevating body 93 is raised, the front and rear sliders 86 are advanced to above the second standby position, while the air cylinder device 116 is driven to raise the suction base retainer 117 to raise the suction base. The pantograph 114 moves away from the upper edge of 113 and is driven by the motor 110.
Closes. At the same time, after the even-numbered mounting holes 7 are mounted on the odd-numbered row, the left and right sliders 97 return to the left by half the pitch of the mounting holes 7, while the odd-numbered mounting holes 7 are mounted on the even-numbered row. The right and left sliders 97 do not move after the is installed.

When the chip 2 is conveyed, the pantograph 114 is first closed and the front and rear sliders 86 are thus closed.
, And the vacuum adsorbers 118a, ..., 118m are located at the second standby position on the right side of the belt conveyor 15 for chips.
Located on the row of. At this time, the vacuum adsorber 118a at the left end
Are located above the chip 2 at the left end. Also, when the pantograph 114 is closed, the vacuum adsorbers 118a, ..., 118m
Since the diameter of the flange 3 of the body 1 and the diameter of the tip 2 are equal, the pitch is equal to the pitch of the tips 2 closely arranged in the second standby position, and therefore, the vacuum suction elements 118a, ..., 118m is 13 from the left first
Located above chip 2 up to the second. Then the lifting body
93 descends, and the respective vacuum adsorbers 118a, ..., 118m come into contact with the upper surface of each body 1. Then, each vacuum adsorber 118a, ...,
A predetermined one of 118 m is in a negative pressure state, and after adsorbing a predetermined chip 2, the elevating body 93 rises. At this time, the number of chips 2 to be adsorbed and the vacuum adsorber that is in a negative pressure state
The relationship with 118a, ..., 118m is the same as when the body 1 is transported. In addition to this, when, for example, four chips 2 are conveyed, the solenoid valve 48a is turned on, and the pressing pieces 47e, 47f are driven by the air cylinder devices 46e, 46f.
Moves above both chips 2 adjacent to both sides of the four chips 2 to be conveyed. Similarly, when 7 chips 2 are transported, the solenoid valve 48b is turned on,
When the presser pieces 47d, 47g convey nine chips 2, the solenoid valves 48c, 48d are turned on, and when the presser pieces 47c, 47h convey ten chips 2, the solenoid valves 48d, 48e. When the pressing pieces 47b and 47h carry 11 chips 2 by turning on, the solenoid valves 48e and 48f turn on and the pressing pieces 47b and 47i are placed on both sides of the chip 2 group to be carried. Proceed above both adjacent chips 2. When carrying 12 chips 2, the solenoid valve 48f,
When 48g is turned on and the presser piece 47i conveys 13 chips 2, the solenoid valve 48g is turned on and the presser piece 47j moves to the right of the chip 2 group to be conveyed. Go up. Since the chip 2 is thin, when some of the chips 2 lined up in close contact at the second standby position are picked up and lifted, if there is no presser, the chip 2 adjacent to the chip 2 to be lifted is turned up. There is a risk that it will be lifted as described above.
…, 47j can be surely prevented by pressing the chip 2 from above. On the other hand, when 12 or 13 chips 2 are transferred, the pressing piece 47a, which is a stopper against the transfer of the chips 2 by the chip belt conveyor 15, is retracted by turning on the solenoid valve 48g, so that the leftmost chip 2 can be easily lifted. . However, this is not always necessary. It should be noted that the solenoid valves 48a, ..., 48g are turned on only for a short time during which the chip 2 is adsorbed and lifted.

After the elevating body 93 is raised, the front and rear sliders 86 are retracted, and the rows of the vacuum adsorbers 118a, ..., 118m are
It is located above the row of bodies 1 on which the chips 2 in the tray 6 are to be placed. During the retreat, the pantograph 114 is opened similarly to the case where the body 1 is transferred, and when the chips 2 are transferred to the body 1 in the odd numbered row of the tray 6, the left and right sliders 97 are moved by half the pitch of the mounting holes 7. Move to the right. Then, the predetermined vacuum adsorbers 118a, ..., 11
After each chip 2 adsorbed to 8 m is positioned above each body 1 on which it is to be placed, the lifting body 93 descends and the lifting table 128 rises, and each pin 13
3 passes through each through hole 134 of the table 13 and each mounting hole 7 of the tray 6, and is inserted from below into each body 1 including the chip 2 already mounted, and the body 1 is temporarily lifted. As a result, a new chip 2
The upper surface of each body 1 on which the
…, Each chip 2 adsorbed at 118 m is closely faced or abutted from below. Then, the adsorption by the vacuum adsorbers 118a, ..., 118m is released, and the chips 2 adsorbed by the vacuum adsorbers 118a, ..., 118m are transferred onto the respective bodies 1. At this time, the convex portion 5 of the chip 2 is inserted into the concave portion 4 of the body 1.
Fits in. Then, the elevating table 128 descends, and its pins 133 come out of the through holes 134 of the table 13 and the mounting holes 7 of the tray 6. Along with the lowering of the pins 133, the respective bodies 1 also descend and are reinserted into the respective mounting holes 7 of the tray 6. In this way, the chip 2 is transferred from the second standby position to the tray 6.

After that, after the elevating body 93 rises, the front and rear sliders 86 advance to above the first standby position, during which the pantograph 114 closes and the even number of bodies 1 are attached to the odd numbered rows. After that, the left and right sliders
97 returns to the left by half the pitch of mounting hole 7.

After removing the body 1 or the tip 2 from the first standby position or the second standby position, the first standby position is removed.
From the standby position or the second standby position of the belt conveyor 16 until the body 1 or the tip 2 is removed,
By carrying 17, the body 1 or the chip 2 is lined up in a close contact state with the first standby position or the second standby position.

As described above, according to the configuration of the above embodiment, the mounting of the body 1 and the chip 2 on the tray 6 can be completely automated. Therefore, the body 1 and the chip 2 can be reliably and accurately mounted on the tray 6 in a short time without labor, and the productivity is improved. Further, since the work transfer / positioning mechanism 19 is commonly used by the body 1 and the chip 2, the entire apparatus can be made compact and its structure can be simplified. Moreover, the tray transport positioning mechanism 18 is arranged in the center, the body supply mechanism 14 is arranged on the right side, the chip supply mechanism 15 is arranged on the left side, and both the body belt conveyor 16 and the chip belt conveyor 17 are arranged. The first standby position on the right side of the body belt conveyor 16 and the second standby position on the left side of the chip belt conveyor 17 are arranged side by side in the front-rear direction while being arranged in the left-right direction.
Furthermore, the tray 6 is attached when the body 1 and the tip 2 are mounted.
Since the mounting predetermined position 53 for positioning and the both standby positions are lined up in the front and rear, the entire apparatus can be made more compact and its structure can be made simpler. Further, the ceramic ring 9 in the tray 6, the pressing pieces 47a, ..., 47j in the chip supply mechanism 15, the suction base pressing 117 of the work transfer positioning mechanism 19, the work transfer mechanism 20, etc., are as described above. Have an effect.
