It is the front view seen from 4.

  The substrate supply device 12 is provided in a mounting system for mounting electronic components such as a TCP (Tape Carrier Package), a driver IC, and a flexible substrate on a glass panel, a flexible substrate, a printed circuit board (hereinafter referred to as a substrate) 14, for example. One of the devices to be used.

  The substrate supply device 12 takes out the substrate 14 from a main tray (first tray) 16 in which the substrate 14 is accommodated, and the taken-out substrate 14 is provided in a subsequent device such as a mounting device that is a device for mounting electronic components. The supplied substrate mounting position 18 is supplied. The substrate supply apparatus 12 includes a main table (first table) 20 and a sub table (second table) 22 that support the substrate 14 and can move in the y-axis direction. The substrate supply apparatus 12 includes a substrate supply head 24 that is movable in the x-axis direction and the z-axis direction and supplies the substrate 14 supported by the main table 20 or the sub-table 22 to the substrate placement position 18. .

  The main table 20 is a table that supports the main tray 16 containing a plurality of substrates 14 at a predetermined position. The main table 20 can be moved in the y-axis direction while supporting the main tray 16 by a main table moving mechanism section (first tray moving mechanism section) 21, and includes a tray supply position 38 and a tray collection position 40. Move between. The tray supply position 38 is a position where the unused main tray 16 full of the substrates 14 is placed on the main table 20. The tray collection position 40 is a position where the used main tray 16 with the substrate 14 emptied is collected from the main table 20. In addition, when the present embodiment has been used, for example, even when the substrate 14 remains in the main tray 16, the remaining number of the substrates 14 accommodated in the main tray 16 becomes less than a predetermined number. May also be included when it is determined that it has been used or should be replaced.

  The main tray 16 is a tray having a plurality of depressions arranged vertically and horizontally, and is placed on the main table 20 so that the depressions are arranged in the x-axis direction and the y-axis direction. A substrate 14 is accommodated in each recess. By accommodating the substrate 14 in such a main tray 16, the substrate 14 made of glass or the like that is easily damaged can be prevented from being damaged, and the substrate 14 can be positioned at a predetermined position on the main table 20.

  The substrate 14 is taken out from the main tray 16 when the substrate supply head 24 lifts in the z-axis direction. Therefore, each recess of the main tray 16 has a shape and a dimension that allow the substrate 14 to be easily taken out from above.

  The substrate supply head 24 includes a base portion 26 and, for example, four suction nozzles 28 fixed to the base portion 26. The substrate supply head 24 is moved by the first substrate supply head moving mechanism 30 in the x-axis direction, and is moved by the second substrate supply head moving mechanism 32 in the z-axis direction.

  Each of the suction nozzles 28 has a downward opening that communicates with a decompression means (not shown). Each opening is positioned at the same height, and is provided in the base portion 26 so as to be in contact with the vicinity of the four corners in the substrate 14. The substrate supply head 24 sucks and holds the substrate 14 from above by the suction force of the suction nozzle 28, and takes out the substrate 14 from the main tray 16.

  The sub-table 22 is a table that supports a sub-tray (second tray) 34 containing a plurality of substrates 14 supplied during setup in a predetermined position, and is moved in the y-axis direction by a sub-table moving mechanism 36. I can move. The sub table 22 is provided side by side with the main table 20 in the x-axis direction, and is disposed between the main table 20 and the substrate placement position 18.

  Here, the setup is an exchange operation of the main tray 16 placed on the main table 20, and in detail, when all the substrates 14 accommodated in the main tray 16 are supplied, they are used. The main tray 16 is replaced with an unused main tray 16 in which the substrate 14 is accommodated.

  The sub-table 22 can support a number of substrates 14 equal to or greater than a certain number (hereinafter referred to as a unit quantity) greater than the number of substrates 14 necessary for continuously supplying the substrates 14 during setup.

  Here, a method for calculating the unit quantity will be described with a specific example. It is assumed that the time (tact) A required for the substrate supply head 24 to supply one substrate 14 from the sub-table 22 is 3 seconds, and the time B required for setup is 12 seconds. In this case, the number of the substrates 14 necessary for continuously supplying the substrates 14 during the setup is four, which is the number obtained by dividing the time B required for the setup by the tact A. In this case, the smaller the unit quantity, the smaller the subtable 22 can be made. Therefore, the unit quantity is preferably determined to be four, but may be more, for example, five. When the unit quantity is five, if the tact A is 3 seconds and the time B required for setup is 12 seconds, the time for supplying the substrate 14 of the unit quantity from the sub-table 22 is 15 seconds (= tact A 3 seconds × 5), which is longer than the time B required for setup, 12 seconds. Here, it is conceivable to leave one substrate 14 on the sub-table 22 and supply the substrate 14 from the main table 20 after the setup is completed, but it is preferable to continuously execute the same operation. A unit quantity of substrates 14 is supplied from the sub-table 22. For this reason, when the quantity larger than the quantity calculated from the tact A and the time B required for the setup is used as the unit quantity, the main table 20 is in a state in which the setup has been completed for a while (in the above example, the unit quantity is 5 sheets). In this case, it will wait for 3 seconds.

  Further, for example, it is assumed that the tact A is 3 seconds and the time B required for setup is 11 seconds. In this case, since B is not divisible by A, the number of substrates 14 necessary for continuously supplying the substrate 14 during the setup is four, which is the minimum number larger than the number obtained by dividing B by A. . Accordingly, the unit quantity in this case may be determined as an arbitrary number of four or more as in the above example, but is preferably four.

  In this way, by supporting the substrate 14 in a unit quantity more than necessary for the substrate 14 to continuously supply the substrate 14 during the setup, the substrate 14 is continuously attached even during the setup. The idle time during setup can be eliminated.

  Further, the number of substrates 14 supported by the sub-table 22 is preferably an integral multiple of the unit quantity. As a result, when the setup is completed, the substrate 14 accommodated in the sub-tray 34 can be used up, and the production management of the mounting substrate is facilitated.

  The sub-tray 34 has a plurality of indentations arranged, for example, vertically and horizontally in the same manner as the main tray 16. Each of the indents of the sub-tray 34 can hold the position of the substrate 14, and the substrate 14 can be easily moved from above. It has a shape and dimensions that can be taken out. The sub-tray 34 is placed on the sub-table 22 so that a plurality of depressions that accommodate the substrate 14 are arranged in the x-axis direction and the y-axis direction.

  The sub-table 22 may be mounted with a single sub-tray 34 that can store substrates of an integral multiple of the unit quantity. However, the sub-tray 34 may be composed of a plurality of small trays with a small number of sheets that can be stored. In this case, by placing a plurality of small trays on the sub-table 22, the sub-table 22 supports the sub-tray 34 in which substrates of an integral multiple of the unit quantity are accommodated. That is, the small tray is a tray in the case where the sub-tray 34 includes a plurality of trays, and is a tray that accommodates substrates less than an integral multiple of the unit quantity.

  Further, the substrate supply device 12 includes a main tray supply device 42 that supplies the main tray 16 to the main table 20 and a main tray collection device 44 that collects the main tray 16 from the main table 20 for setup.

  The main tray supply device 42 is a device that supplies the unused main tray 16 to the main table 20 when the main table 20 is at the tray supply position 38. The main tray supply device 42 includes a supply tray mounting table 46 that supports an unused main tray 16 in which substrates are accommodated, and a lifting unit for the supply tray mounting table 46 that moves the supply tray mounting table 46 in the z-axis direction. 48.

  The supply tray mounting table 46 supports a plurality of unused main trays 16 stacked below the tray supply position 38. The unused main tray 16 is appropriately mounted on the supply tray mounting table 46 by the operator.

  The raising / lowering section 48 of the supply tray mounting table can raise and lower the supply tray mounting table 46 in a state where the unused main tray 16 is mounted, and has a certain height below the tray supply position 38. The upper end of the uppermost unused main tray 16 is maintained. The height of the upper end of the uppermost unused main tray 16 is monitored by, for example, a sensor (not shown), and the operation of the elevating unit 48 of the supply tray mounting table is controlled based on information acquired from the sensor or the like. Is done. Accordingly, the upper end of the main tray 16 placed on the supply tray placing table 46 is maintained lower than, for example, the lower end of the main table 20, that is, a height that does not hinder the movement of the main table 20 in the y-axis direction. .

  The main tray supply device 42 also holds a base 50 and four suction nozzles 52 fixed to the base 50 in order to hold the unused main tray 16 from the supply tray mount 46 and transfer it to the main table 20. The main tray supply head 54 has a tray supply head moving mechanism 56 for moving the main tray supply head 54 in the z-axis direction.

  Each of the suction nozzles 52 has a downward opening that communicates with a decompression means (not shown). Each opening is disposed so as to be in contact with the vicinity of the four corners in the main tray 16 mounted on the supply tray mounting table 46. By such suction force of the suction nozzle 52, for example, the uppermost one of the unused main tray 16 supported by the supply tray mounting table 46 is sucked and held.

  The main tray collection device 44 is a device that collects the used main tray 16 from the main table 20 when the main table 20 is at the tray collection position 40. The main tray collection device 44 includes a collection tray mounting table 58 that supports the used main tray 16 and a collection tray mounting table lifting unit 60 that moves the collection tray mounting table 58 in the z-axis direction.

  The collection tray mounting table 58 supports a plurality of used main trays 16 stacked below the tray collection position 40. The used main tray 16 is appropriately removed from the collection tray mounting table 58 by the operator.

  The elevating unit 60 of the collection tray mounting table can raise and lower the collection tray mounting table 58 in a state where the used main tray 16 is mounted, and has a certain height below the tray collection position 40. The upper end of the uppermost used main tray 16 is maintained. The height of the upper end of the used main tray 16 is monitored by, for example, a sensor (not shown), and the operation of the lifting / lowering unit 60 of the collection tray mounting table is controlled based on information acquired from the sensor or the like. As a result, the upper end of the main tray 16 placed on the collection tray mounting table 58 is maintained lower than, for example, the lower end of the main table 20, that is, a height that does not hinder the movement of the main table 20 in the y-axis direction. .

  The main tray collection device 44 also includes a base 62 and four suction nozzles fixed to the base 62 in order to lift the used main tray 16 from the main table 20 and transfer it onto the collection tray mounting table 58. 64, and a tray collection head moving mechanism 68 for moving the main tray collection head 66 in the z-axis direction.

  Each of the suction nozzles 64 has a downward opening that communicates with a decompression means (not shown). Each opening is arranged so as to be in contact with the vicinity of the four corners in the main tray 16 supported at a predetermined position of the main table 20. The used main tray 16 is sucked and held by the suction force of the suction nozzle 64.

  The substrate supply device 12 further includes a control unit 70. The control unit 70 has a notification unit 72 such as a lamp or a speaker for controlling the movement of the above-described units and notifying the operator when all the substrates 14 supported by the sub-table 22 are used. The control unit 70 counts the number of substrates 14 supplied from the sub-tray 34 by the substrate supply head 24, acquires information on the presence / absence of the component from a sensor (not shown) that detects the presence / absence of the component in the sub-tray 34, etc. It is determined whether or not all the substrates 14 supported by the sub-table 22 have been used.

  The configuration of the substrate supply device 12 according to the present embodiment has been described above. Next, the operation of the substrate supply apparatus 12 will be described with reference to FIGS.

FIG. 3 is a time chart showing the operation of the substrate supply apparatus 12. 3, the position and location of the main table 20 the substrate supply head 24 from the unused main tray 16 from the time T ₁₀ the supply of the first substrate 14 is started to the time T ₃₀ the setup of two ends Show.

First, the substrate feed head 24 is located above the main tray 16, and supplies the substrate 14 from the main tray 16 (time _T 10 _{through T 13} and the time _T 20 _~T 23). In the present embodiment, the substrates 14 of the main tray 16 are arranged in two rows in the y-axis direction, with the row in the x-axis direction being a row. Therefore, on the way to supply the substrate 14 from the main tray 16 (time _T 11 _{through T 12} and the time _T 21 _{through T 22),} the main table 20 is moved in the y-axis direction switching a substrate supply position at the board supply position Thus, the substrate 14 to be supplied is positioned with respect to the substrate supply head 24.

During setup (time _T 13 _{through T 20} and the time _T 23 _{through T 30),} the board supply head 24 supplies the substrate 14 from the sub-tray 34 located above the sub-tray 34 (time _T 14 _{through T 19} and the time T _{24 to} T ₂₉ ), the table of the tray from which the substrate 14 is taken out is switched by moving between the main tray 16 of the main table 20 and the sub-tray 34 of the sub-table 22 so that the substrate 14 can be continuously supplied. During setup, the main table 20 is moved from the substrate supply position in the tray collecting position 40 (time _T 13 _{through T 15} and the time _T 23 _{through T 25),} the spent main tray 16 is collected tray supply position Go to 38 (time _T 15 _{through T 17} and the time _T 25 _{~T 27),} the unused main tray 16 is fed back to the substrate supply position (time _T 17 _{through T 20} and the time _T 27 _{through T 30} ).

  Details of the operation of the substrate supply apparatus 12 will be described in time series with reference to FIG. In addition, with reference to FIG. 4 to FIG. 8, the positional relationship of the main components of the substrate supply apparatus 12 from immediately before the setup to the end of the setup will be described. 4 to 8 show an example in which the sub-table 22 supports eight substrates 14 that are twice the unit quantity.

Time T ₁₀ : The substrate supply head 24 starts supplying the substrate 14 from the main tray 16. The main table 20 is in the substrate supply position. The supply of the substrate 14 is accommodated in the depressions in the first row, which are arranged in the x-axis direction closest to the tray collection position 40 among the substrates 14 accommodated in the main tray 16, and are supplied to the substrate placement position 18. It starts with the substrate 14 housed in the first row of depressions that are arranged in the near y-axis direction.

  Here, details of the substrate supply operation in which the substrate supply head 24 supplies one substrate 14 will be described. The substrate supply head 24 moves downward to bring the tip of the suction nozzle 28 into contact with the vicinity of the four corners of the substrate 14 stored in the main tray 16 (sub-tray 34), and sucking the substrate 14 in contact therewith. Return upward while holding. Thereby, the substrate 14 is taken out from the main tray 16 (sub-tray 34). Thereafter, the substrate supply head 24 moves in the x-axis direction to above the substrate placement position 18 while holding the substrate 14, moves downward, places the substrate 14 at the substrate placement position 18, and stops suction. And move upward. As a result, the substrate 14 is supplied to the substrate mounting position 18. After supplying the substrate 14, the substrate supply head 24 moves in the x-axis direction to above the next substrate 14 on the main tray 16. Thus, one substrate supply operation is completed.

Time T _{10 to} T ₁₁ : The substrate supply head 24 moves the depression of the main tray 16 for taking out the substrate 14 sequentially in the first row, the second row, and the third row in the direction away from the substrate placement position 18. By repeating the substrate supply operation, the substrate 14 accommodated in the depression in the first row of the main tray 16 is supplied.

Time T _{11 to} T ₁₂ : When the substrate supply head 24 supplies all the substrates 14 accommodated in the depressions in the first row of the main tray 16 (time T ₁₁ ), the main table 20 is moved to one row of the main tray 16. The tray moves toward the tray collection position 40 by a distance corresponding to minutes. As a result, the depressions in the second row, which are the second closest to the tray collection position 40 in the x-axis direction, are positioned below the substrate supply head 24.

  As described above, the positions of the substrate 14 taken out from the main tray 16 in the x-axis direction and the y-axis direction are determined by the movement of the substrate supply head 24 and the main tray 16. For this reason, the moving mechanism for positioning the substrate supply head 24 with respect to the substrate 14 to be extracted only needs to move the main tray 16 and the substrate supply head 24 in only one direction. It becomes possible to make it small.

Time _T 12 _{through T 13:} substrate feed head 24 are sequentially supplied to the substrate 14 housed in a recess of the second line of the main tray 16, the substrate 14 of the main tray 16 is supplied all (time _{T 13)} . FIG. 4 shows a state of the substrate supply apparatus 12 immediately before the last substrate 14 accommodated in the main tray 16 is supplied.

Time T ₁₃ : Setup starts here.

The operation of the substrate supply head 24 during setup will be described first.
Time T _{13 to} T ₁₄ : The substrate supply head 24 moves from above the main tray 16 to above the sub-tray 34.

Times T _{14 to} T ₁₉ : As with the main tray 16, the substrate supply head 24 is the first row in the x-axis direction closest to the tray collection position 40 among the substrates 14 accommodated in the sub-tray 34. The substrate 14 accommodated in the first row of depressions that are housed in the eye depressions and arranged in the y-axis direction close to the substrate placement position 18 is supplied. When the substrate 14 of the sub-tray 34 is supplied, the operation performed by the substrate supply head 24 to supply one substrate is the same as the case of supplying the substrate of the main tray 16 described above.

  The substrate supply head 24 moves the recesses of the sub-tray 34 for taking out the substrate 14 sequentially in the first row and the second column in the direction away from the substrate mounting position 18 and accommodates them in the recesses of the first row of the sub-tray 34. All the substrates 14 to be processed are supplied. Thereafter, the sub table 22 moves toward the substrate placement position 18 by a distance corresponding to one row of the sub tray 34. As a result, the depressions in the second row, which are the second closest to the tray collection position 40 in the x-axis direction, are positioned below the substrate supply head 24. The substrate supply head 24 sequentially supplies the substrates 14 accommodated in the depressions in the second row of the sub-tray 34.

  As described above, the positions of the substrate 14 taken out from the sub-tray 34 in the x-axis direction and the y-axis direction are determined by the movement of the substrate supply head 24 and the sub-tray 34 as in the case of the main tray 16. The sub-tray 34 is arranged in parallel with the main tray 16 so as to be movable in the same direction as the main tray 16. For this reason, the moving mechanism for positioning the substrate supply head 24 with respect to the substrate 14 to be extracted only needs to move the main tray 16 and the substrate supply head 24 in only one direction. It becomes possible to make it small.

Time T _{19 to} T ₂₀ : The substrate supply head 24 moves from above the sub-tray 34 to above the main tray 16. At this time, the substrate supply head 24 moves above the substrate 14 accommodated in the first row of depressions arranged in the y-axis direction closest to the substrate placement position 18.

Next, the operation of the main table 20 during setup will be described.
Time T _{13 to} T ₁₅ : The main table 20 moves from the substrate supply position to the tray collection position 40. Further, at times T _{13 to} T ₁₅ , the main tray supply head 54 holds the main tray 16 supported by the supply tray mounting table 46 and moves it above the tray supply position 38, whereby the main tray 16 Prepare for supply.

Here, the details of the main tray supply operation in the main tray supply operation will be described. The preparation for supplying the main tray is preferably started from a time close to the start of setup (time T ₁₃ ), but may be performed at any time as long as the preparation is finished at times T _{10 to} T ₁₇ .

  The supply tray mounting table 46 is raised by a height corresponding to the thickness of the main tray 16 by the elevating unit 48, and the main tray supply head 54 moves downward. As a result, the tip of the suction nozzle 52 comes into contact with the vicinity of the four corners of the main tray 16 supported on the top of the supply tray mounting table 46. At this time, by raising the supply tray mounting table 46 and lowering the main tray supply head 54, the movement range of the both can be reduced, so that the respective moving mechanisms 48 and 56 can be reduced.

Subsequently, the main tray supply head 54 holds the main tray 16 by sucking the vicinity of the four corners of the main tray 16. The main tray supply head 54 moves up while holding the main tray 16 so that the main table 20 moving to the tray supply position 38 and the main tray 16 do not interfere with each other. The main tray supply head 54 stands by while being held while holding the main tray 16 until the main table 20 moves to the tray supply position 38. Thus, the supply ready for the main tray ends, continuation of the main tray feeding operation is executed at time T ₁₇ through T _18.

Time _T 15 _{through T 16:} Yes main table 20 into the tray collecting position 40, the main tray 16 is held by the main tray recovery head 66 is moved upward. As a result, the main tray 16 is collected from the main table 20. FIG. 5 shows a state in which the main tray 16 is moved upward from the main table 20 at the tray collection position 40 by the main tray collection head 66.

Here, details of the main tray collection operation will be described. When the main table 20 moves to the tray collection position 40, the main tray collection head 66 moves downward. As a result, the tip of the suction nozzle 28 comes into contact with the vicinity of the four corners of the used main tray 16 from which the substrate 14 placed at a predetermined position of the main table 20 at the tray collection position 40 is taken out. Next, the main tray collection head 66 holds the main tray 16 by sucking the vicinity of the four corners of the main tray 16. The main tray collection head 66 moves up while holding the main tray 16 so that the main table 20 can be retracted from the tray collection position 40. Thus, recovery from the main table 20 is finished, a continuation of the main tray recovery operation is performed at time _T 17 _{through T 20.}

Time _T 16 _{through T 17:} the main table 20, in a state where the main tray 16 is not mounted, to move from the tray collecting position 40 in the tray feeding position 38. FIG. 6 shows a state where the main table 20 is moving from the tray collection position 40 to the tray supply position 38.

Time T _{17 to} T ₁₈ : The main table 20 is positioned at the tray supply position 38, and the unused main tray 16 is placed on the main table 20. FIG. 7 shows a state where the main table 20 is at the tray supply position 38 (time T ₁₇ ). The main tray supply head 54 that has been waiting after the main tray supply preparation operation (time T _{13 to} T ₁₅ ) places the main tray 16 on the main table 20 moved to the tray supply position 38 and performs suction. Stop. After the unused main tray 16 is supplied, the main tray supply head 54 rises and returns to a predetermined position before setup. Thus, the main tray supply operation ends.

During this time, the main tray collection head 66 places the main tray 16 held at times T _{13 to} T ₁₅ on the main table 20. As a result, the used main tray 16 is collected.

Here, the continuation of the main tray recovery operation described at time _T 15 _{through T 16} will be described. The main tray collection head 66 moves downward and stops the suction when the main tray 16 being held is positioned at the uppermost stage of the collection tray mounting table 58. As a result, the used main tray 16 is placed on the collection tray mounting table 58. Thereafter, the collection tray mounting table 58 is lowered by the height corresponding to the thickness of the main tray 16 by the elevating unit 60. The main tray collection head 66 on which the main tray 16 is placed rises and returns to a predetermined position before setup. Thus, the main tray collection operation ends. The tray collection operation is preferably performed after collection from the main table (times T _{15 to} T ₁₆ ) and after the main table 20 has moved from the main tray collection position 40, but the next tray collection operation is performed. It suffices to finish the process by the start time (time T ₂₅ ).

Time _T 18 _{through T 20:} the main tray 16 is moved from the tray supply position 38 in the substrate feeding position. At this time, the main tray 16 is in an unused state. Therefore, the main table 20 moves in the y-axis direction so that the substrates 14 accommodated in the depressions in the first row that are arranged in the x-axis direction closest to the tray collection position 40 can be supplied.

Time T ₂₀ : Setup is completed, and the substrate supply head 24 starts supplying the substrate 14 from the main tray 16 again. FIG. 8 shows a state where the supply of the substrate 14 from the unused main tray 16 is started.

Then, the substrate feeding device 12, at time _T 20 _{through T 23,} to perform the same operation as the time _T 10 _{through T 13} described above. Thus, when the substrate 14 accommodated in the main tray 16 is supplied all at time _T 23 _{through T 30} continues, the board supply device 12 again performs the same setup as the time _T 13 _{through T 20} described above . It is desirable that the substrate 14 supplied from the sub-tray 34 in the setup at this time follows the substrate 14 supplied in the previous setup, and the operation of the substrate supply head 24 and the sub table 22 can be minimized.

  Specifically, in the present embodiment, the substrate 14 supplied in the previous setup is the last substrate 14 accommodated in the depression of the row in which it is accommodated (second row of the sub-tray 34). The substrate accommodated in the depressions in the row adjacent to the row (the third row of the sub-tray 34) is supplied.

  In addition, when the board | substrate 14 supplied by the last setup was a board | substrate accommodated in the hollow in the middle of the row | line in which it is accommodated, it supplies by the last setup among the board | substrates 14 accommodated in the row. Substrate 14 adjacent to the substrate 14 is supplied.

Returning to FIG. 3, in this embodiment, when the two setups are completed (time T ₃₀ ), all the substrates 14 accommodated in the sub-tray 34 are supplied, and the sub-tray 34 is used. The control unit 70 determines that all the substrates 14 supported by the sub-table 22 have been used. Under the control of the control unit 70, the notification unit 72 notifies the operator that the sub-tray 34 has been used. The operator who has received the notification replaces the used sub-tray 34 with the unused sub-tray 34, whereby the eight substrates 14 are again supported by the sub-table 22.

  By repeating the operations described so far, the substrate supply apparatus 12 can continuously supply the substrate 14 without generating an idle time during setup.

  As mentioned above, although Embodiment 1 of this invention was demonstrated, Embodiment 1 is not restricted to this.

  For example, the sub-tray may contain a substrate used for a special purpose such as a conditioned substrate. The condition-determining substrate is a substrate used for determining mounting conditions by adjusting the position and temperature of a subsequent device such as a mounting device.

  A substrate used for a special purpose is arranged, for example, in a part of a region where a marking is attached to the sub-tray. This makes it possible to adjust each device during setup using the substrates accommodated in the sub-tray.

  For example, the substrate supply head 24, the main tray supply head 54, and the main tray collection head 66 are all held to hold the substrate 14 or the main tray 16. Suction is only an example of a method for holding the substrate 14 or the main tray 16. For example, the substrate supply head may have four arms facing each other in the x-axis direction and the y-axis direction. In this case, one end of each arm is attached to the substrate 14 so that the opposite arm opens and closes. The other end of each arm has a claw protruding in the closing direction of the arm. When such an arm is closed, the claw sinks under each of the four sides of the substrate 14 and supports the substrate 14 when the substrate supply head is raised. Thereby, the substrate 14 can be taken out from the main tray 16 and the sub-tray 34, and the taken-out substrate 14 can be held during movement. This modification can be applied to both the main tray supply head 54 and the main tray collection head 66.

  As described above, according to the present embodiment, the main table 20 and the sub-table 22 move in the y-axis direction, and the substrate supply head 24 moves in the x-axis direction. Thus, the substrate supply head 24 can be positioned above each substrate accommodated side by side in the x-axis direction and the y-axis direction, and the substrate 14 can be taken out from each of the main tray 16 and the sub-tray 34. Therefore, it is not necessary to move the substrate supply head 24 in the y-axis direction, and the moving mechanism of the substrate supply head 24 can be made simple and small. In addition, it is not necessary to move the main table 20 and the sub table 22 in the x-axis direction, and the moving mechanisms of the main table 20 and the sub table 22 can have a simple configuration and can be made compact.

  The main table 20 moves in the y-axis direction for setup. This is the same as the direction in which the main table 20 moves to supply the substrate 14. Further, the movement range at the time of substrate supply is included in the movement range at the time of setup. Therefore, the main table 20 can realize the movement necessary for substrate supply only by the main table movement mechanism section 21 having a function necessary for the setup, and the substrate supply apparatus 12 as a whole has a simple movement mechanism. It becomes possible to become.

  Furthermore, since the main table 20 on which the main tray 16 is placed and the sub table 22 on which the sub tray 34 is placed are provided side by side in the x-axis direction, the main tray 16 can be moved without moving the substrate supply head 24 in the y-axis direction. The substrate can be supplied from the sub-tray 34. Thereby, the moving mechanism of the substrate supply head 24 can be simplified.

(Embodiment 2)
The configuration and operation of the substrate supply device 12 described in the first embodiment can also be applied to the configuration and operation of the mounting substrate recovery device 112 shown in FIG. In the second embodiment, an example of the mounting board recovery apparatus 112 will be described.

  The mounting board collection device 112 is one of the devices provided in the mounting system to be mounted similar to the first embodiment, and is a device that collects the mounting board manufactured in the mounting system. That is, the mounting board is a board such as a glass panel, a flexible board, or a printed board on which electronic components such as a TCP (Tape Carrier Package), a driver IC, and a flexible board are mounted. In the mounting line formed by the mounting system, when the device provided in the front stage of the mounting substrate recovery device 112 positions the mounting substrate 114 at a predetermined substrate mounting position 118, the mounting substrate recovery device 112 is mounted at the substrate mounting position 118. The mounted mounting substrate 114 is sequentially accommodated in the collecting trays 116 and 134, and the collecting trays 116 and 134 in which the mounting substrate 114 is accommodated are collected.

  The mounting board collection device 112 is a device that collects the mounting boards by accommodating a plurality of mounting boards 114 on which components are mounted in the trays 116 and 134, and is a predetermined device by a device provided in the previous stage in the mounting system. The mounting substrate 114 placed at the substrate placement position 118 is picked up and moved and accommodated in the main tray 116.

  The mounting substrate collection device 112 includes a main table 120 and a sub table 122 that support the mounting substrate 114 and can move in the y-axis direction, and a substrate collection head 124 that moves in the x-axis direction and the z-axis direction. The substrate collection head 124 moves in the x-axis direction and the z-axis direction, thereby moving the mounting substrate 114 from the substrate placement position 118 and placing it on the main tray 116 or the sub table 122 placed on the main table 120. The mounting board 114 is accommodated in the placed sub-tray 134. Each component of the mounting substrate collection device 112 is the same as the corresponding component of the substrate supply device 12. The difference is the position where the sub-table 122 is arranged, and the sub-table 122 is preferably provided between the substrate mounting position 118 and the main table 120 in line with the main table 120 in the x-axis direction. As a result, a space for maintaining the drive system around the main table 120 can be secured, and the maintainability can be improved.

  The mounting board collecting device 112 sequentially stores the mounting boards in the unused main tray 116, and when the main tray 116 becomes used, the main tray 116 is replaced (set up). Here, in the mounting board recovery apparatus 112, the unused main tray 116 is a tray having the same structure as the main tray 16 of the first embodiment, and does not contain the mounting board 114. In addition, the used main tray 116 contains a number of mounting boards 114 that can be accommodated in the main tray 116. In addition, the used state of the present embodiment may be a case where the operator determines that the used board has been used or replaced, for example, when a predetermined number of mounting boards 114 are housed even if the number is less than the houseable number. May be included.

  During setup, the main table 120 is located between a tray supply position 138 where an unused main tray 116 in which the mounting substrate 114 is not accommodated is supplied and a tray collection position 140 where the used main tray 116 is collected. Move in the y-axis direction. An unused main tray 116 is supplied to the main table 120 at the tray supply position 138 by a main tray supply device 142 included in the mounting board recovery device 112. In addition, the main table 120 at the tray collection position 140 collects the used main tray 116 containing the mounting substrate 114 by the main tray collecting device 144 provided in the mounting substrate collecting device 112.

  The configurations of the main tray supply device 142 and the main tray recovery device 144 included in the mounting substrate recovery device 112 are the same as the configurations of the main tray supply device 42 and the main tray recovery device 44 included in the substrate supply device 12, respectively.

  The operation executed by the mounting substrate recovery device 112 is that the substrate supply device 12 takes out the substrate from the main tray 16 and the sub-tray 34 and supplies it to the predetermined substrate mounting position 18 from the predetermined substrate mounting position 118. It is the same as that replaced with picking up 114 and accommodating in the main tray 116 and the subtray 134, and collect | recovering. The sub-tray 134 can accommodate more mounting substrates 114 than the number of mounting substrates 114 necessary for the substrate recovery head 124 to continuously recover the mounting substrates 114 when the main tray 116 is replaced.

  The substrate collection head 124 collects the mounting substrate 114 by sequentially housing the mounting substrate 114 in the recesses of the main tray 116. When the main tray 116 is used, the main tray 116 is set up, and the mounting substrate 114 is collected in the sub-tray 134 during that time.

  In the setup, the main table 120 moves to the tray collection position 140, and the main tray collection device 144 collects the used main tray 116. Thereafter, the main table 120 moves to the tray supply position 138, and the main tray supply device 142 supplies an unused main tray 116 in which the mounting substrate 114 is not accommodated. Detailed operations of the main tray supply device 142 and the main tray collection device 144 are the same as those of the main tray supply device 42 and the main tray collection device 44 included in the substrate supply device 12.

  By repeating the above operation, when the mounting substrate 114 is accommodated in all of the recesses of the sub-tray 134 that accommodates the mounting substrate 114 when the main tray 116 is set up, the control device notifies the operator to that effect. Upon receiving the notification, the operator replaces the used sub-tray 134 in which the mounting substrate 114 is accommodated in all the recesses with an unused sub-tray 134 in which the mounting substrate 114 is not accommodated. This makes it possible to collect the mounting board without generating idle time during setup.

  Similarly to the substrate supply device 12, in the mounting substrate recovery device 112, the moving mechanism of the main table 120 on which the main tray 116 is mounted and the sub table 122 on which the sub tray 134 is mounted and the movement of the substrate recovery head 124. The structure of the mechanism and the raising / lowering parts of the main tray supply device 142 and the main tray collection device 144 can be made compact with a simple configuration. Therefore, it becomes possible to make the mounting substrate recovery apparatus simple and small.

  The substrate supply apparatus according to the present invention can be applied to an apparatus that sequentially supplies substrates accommodated in a tray, and the substrate supply method can be applied to such a substrate supply apparatus. The mounting board recovery apparatus according to the present invention can be applied to an apparatus for recovering by sequentially storing mounting boards on which electronic components or the like are mounted in a tray, and the mounting board recovery method is applied to such a mounting board recovery apparatus. be able to.
