Description

  The present invention relates to a component supply apparatus that supplies components stored in a tray to a component mounting means.

  For a component mounting apparatus that mounts an electronic component on a substrate such as a liquid crystal panel or a plasma display panel, a component supply apparatus for supplying the electronic component to the component mounting apparatus is attached. As a parts supply device, a tray containing a plurality of electronic components is stacked on a lifter that can be moved up and down, and the lifter is raised until the uppermost tray is positioned at the parts supply height. There is known a configuration in which an electronic component housed in the device is taken out by a transfer means such as a suction head and supplied to a component mounting device.

  In this component supply apparatus, after all the electronic components have been supplied and the uppermost tray that has been emptied is carried out of the lifter, the lifter is raised to position the next tray at the component supply height. Then, the electronic component supply operation is continued by taking out the electronic component from the new tray positioned at the component supply height by the suction head. By repeating such an operation, the lifter gradually rises toward the component supply height position.

  When the number of stacked trays decreases (or when all the trays are consumed), it is necessary to lower the lifter to the tray replenishment height and to refill the lifter with a new tray by an operator. However, at the tray replenishment timing, since the lifter has risen to the component supply height or in the vicinity thereof, a predetermined time is required to lower the lifter to the tray refill height. Therefore, a wasteful waiting time is generated for the worker until the lifter is lowered to the tray replenishment height, resulting in a problem that the efficiency of the tray replenishment operation is lowered.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a component supply device capable of improving productivity by improving the efficiency of tray replenishment work by an operator.

  As described above, in the present embodiment, the plurality of detection sensors S3 to S5 are arranged in the vertical direction, and the height of the collection side lifter 40 (tray collection stage 33) is determined based on whether or not the inspection light is received at each position. The position is detected, and the amount of the used tray 5A on the tray collection stage 33 is detected based on the detection result. That is, the third detection sensor S3, the fourth detection sensor S4, and the fifth detection sensor S5 serve as a used tray amount detection unit that detects the amount of the used tray 5A on the tray collection stage 33. The used tray remaining amount detection means detects the amount of the used tray 5A based on the height position of the tray collection stage 33. In addition, a detection sensor may be further provided, and the raising / lowering state of the supply-side lifter 20 (collection-side lifter 40) and the amount of the stacked trays 5 may be further subdivided and monitored.

  The supply side lifter control unit 59 controls the raising / lowering operation of the supply side lifter 20 based on the light receiving state of the inspection light by the first light receiving unit U1. Specifically, the supply-side lifter 20 is raised until the inspection light incident on the first light receiving unit U1 is interrupted, and each time the uppermost pallet 12 is taken out by the transfer arm 41, the supply-side lifter 20 is removed. The pallet is raised by one pallet, and the inspection light incident on the first light receiving unit U1 is blocked again, and the uppermost tray 5 is supplied to the tray extraction position A1. Therefore, each time the pallet 12 is taken out from the tray mounting stage 13, the supply-side lifter 20 rises and the number of stacked pallets 12 decreases. The supply-side lifter control unit 59 controls the supply-side lifter 20 according to the operation of the supply-side door opening / closing request switch 46 by an operator or the inspection light receiving state of the first detection sensor S1 and the second detection sensor S2. Move up and down.

  The collection-side lifter control unit 60 controls the lifting and lowering operation of the collection-side lifter 40 based on the inspection light receiving state of the second light receiving unit U3. Specifically, each time the pallet 12 is transferred onto the tray collection stage 33 at the used tray transfer position D1, the incident of the inspection light to the second light receiving unit U3 is blocked, and the collection side lifter Lower 40 by one pallet. That is, the pallet 12 is transferred to the tray collection stage 33 by the transfer arm 41 when the tray collection stage 33 or the uppermost pallet 12 already transferred to the tray collection stage 33 is moved from the used tray transfer position D1. Is also performed at a position lowered by one pallet (see FIGS. 8 to 12). Thus, each time the pallet 12 is transferred to the tray collection stage 33, the collection side lifter 40 is lowered and the number of pallets 12 is increased. The collection-side lifter control unit 60 raises and lowers the collection-side lifter 40 according to the operation of the collection-side door opening / closing request switch 47 by an operator or the inspection light receiving state by the third to fifth detection sensors S3 to S5. .

  The door opening / closing control unit 61 receives the operation of the supply side door opening / closing request switch 46 by an operator, and locks or unlocks the supply side door 44 according to the operating state of the supply side lifter 20. In response to the operation of the collection side door opening / closing request switch 47 by the operator, the collection side door 45 is locked or unlocked according to the operating state of the collection side lifter 40.

  The notification unit 62 is a notification means including a warning sound generator provided in the component mounting device 4, and when the supply side door 44 and the collection side door 45 are unlocked, the pallet 12 on the tray placement stage 13. When the pallet becomes empty, when the pallet on the tray collection stage 33 is full, a warning sound or the like is generated to notify the worker.

  The component supply apparatus 1 of the present invention has the above-described configuration. Next, a component supply operation for supplying the component 3 stored in the tray 5 to the component mounting means using the apparatus will be described. First, the control unit 53 raises the supply-side lifter 20 until the uppermost tray 5 stacked on the tray mounting stage 13 is positioned at the tray extraction position A1. Next, the control unit 53 takes out the pallet 12 holding the uppermost tray 5 by the transfer arm 41. After removing the pallet 12, the control unit 53 raises the supply side lifter 20 by one pallet to supply the uppermost tray 5 to the tray extraction position A1.

  Next, the control unit 53 transfers the pallet 12 held by the transfer arm 41 to the first table 22 or the second table 26 moved to the first position B1. Here, the tray transfer operation in the tray transfer unit 7 will be described in detail with reference to FIGS. 13 and 14. FIG. 13A shows a state in which the first table 22 on which the pallet 12 is placed is located at the second position B2, and the second table 26 on which the pallet 12 is placed is located at the first position B1. Show. At this time, the mounting operation of taking out the component 3 from the tray 5 by the mounting head 51 and mounting it on the substrate 2 is performed at the second position B2. It should be noted that until the mounting operation for the tray 5 placed on the first table 22 moved to the second position B2 is completed (that is, until all the components 3 are removed from the tray 5). The control unit 53 transfers the tray 5 from the tray supply unit 6 to the second table 26 via the transfer arm 41.

  From the state shown in FIG. 13A, the controller 53 lowers the second table 26 to the third position C1 (arrow b1 in FIG. 13B), and then moves it to the fourth position C2 (FIG. 13). 13 (c) arrow c1). Then, the second table 26 is put on standby at the fourth position C2 until all the components 3 are removed from the tray 5 on the first table 22.

  When all the components 3 are removed from the tray 5 on the first table 22, the control unit 53 moves the first table 22 from the second position B2 to the first position B1 (see FIG. 13D). Next, the second table 26 is raised to the second position B2 (arrow d1 in FIG. 13 (e)). That is, here, the second table 26 on which the tray 5 is placed is moved below the first table 22 while the mounting operation for the tray 5 transferred to the first table 22 is being performed. After all the parts 3 are taken out from the tray 5 on the first table 22 and the first table 22 is retracted from the second position B2, the second table 26 is raised and positioned at the second position B2. ing. Then, the control unit 53 executes a loading operation for the tray 5 on the second table 26.

  Next, during the mounting operation for the tray 5 on the second table 26, the control unit 53 takes out the pallet 12 holding the used tray 5A on the first table 22 by the transfer arm 41, and uses the used tray. Transfer to the tray collection stage 33 at the transfer position D1. Thereafter, the control unit 53 takes out the pallet 12 holding the tray 5 supplied to the tray take-out position A1 by the transfer arm 41, and transfers it to the first table 22 at the first position B1. As a result, the tray 5 storing the components 3 is newly placed on the first table 22. When the pallet 12 is transferred onto the tray collection stage 33, the control unit 53 lowers the collection side lifter 40 by one pallet.

  Next, the control unit 53 causes the first table 22 to wait at the first position B1 until all the components 3 stored in the tray 5 on the second table 26 are removed. When all the components 3 stored in the tray 5 on the second table 26 have been taken out, the control unit 53 lowers the second table 26 from the second position B2 to the fourth position C2 (see FIG. 14 (a) arrow d2), and then the first table 22 is moved from the first position B1 to the second position B2 (arrow a2 in FIG. 14B). In other words, here, after the mounting work for the tray 5 placed on the second table 26 is completed and the second table 26 is lowered from the second position B2, the first placed on the tray 5 is placed. The table 22 is moved to the second position B2. Then, the control unit 53 executes a loading operation for the tray 5 on the first table 22.

  At the same time as the first table 22 is moved from the first position B1 to the second position B2, the controller 53 moves the second table 26 from the fourth position C2 to the third position C1 (FIG. 14 (b) arrow c2). Next, the controller 53 raises the second table 26 from the third position C1 to the first position B1 (arrow b2 in FIG. 14C). During the mounting operation for the tray 5 on the first table 22, the control unit 53 takes out the pallet 12 holding the used tray 5 </ b> A on the second table 26 by the transfer arm 41 and performs the tray collection stage 33. Then, the pallet 12 holding the tray 5 supplied to the tray take-out position A1 is taken out and transferred to the second table 26. As a result, the pallet 12 holding the tray 5 storing the components 3 is newly placed on the second table 26.

  As described above, in the present embodiment, during the tray collection operation of collecting the used tray 5A placed on the first table 22 or the second table 26 (via the pallet 12) on the tray collection stage 33, the second Since the tray 5 transferred to the table 26 or the first table 22 is moved to the second position B2, the used tray 5A is retracted from the second position B2 until the tray 5 is newly supplied. It is possible to significantly reduce the time required for the mounting operation and to suppress the interruption of the mounting work. As a result, the supply efficiency of the tray 5 to the component mounting device 4 can be increased and the productivity can be improved. Here, the tray collection operation refers to the operation of retracting the first table 22 or the second table 26 from the second position B 2, so that the tray used tray 5 A is transferred to the tray collection stage 33 by the transfer arm 41. Refers to a series of operations up to the operation performed.

  Next, the operation of the supply side lifter 20 will be described in detail with reference to FIG. The operation described below is executed based on a supply-side lifter control program stored in advance in the component mounting device 4. First, the control unit 53 determines the light receiving state of the first light receiving unit U1 (ST1). Here, when the first light receiving unit U1 is OFF, the control unit 53 raises the supply side lifter 20 (ST2). Next, the control unit 53 determines the light receiving state of the first light receiving unit U1 in the process of raising the supply side lifter 20 (ST3), and raises the supply side lifter 20 until the first light receiving unit U1 is turned on. Let it continue. And the control part 53 stops the raise of the supply side lifter 20 at the timing which the 1st light-receiving part U1 turned ON (ST4).

  Next, when the first light receiving unit U1 is ON in (ST1) or after stopping the ascent of the supply side lifter 20 in (ST4), the control unit 53 is mounted on the tray mounting stage 13. Whether the pallet 12 is empty (zero) or not is determined based on the monitoring status by the lifter state monitoring unit 58 (ST5). That is, when the supply side lifter 20 is in the fourth state (see FIG. 12), it is determined that the pallet 12 is empty.

  If the pallet 12 is not empty, the controller 53 determines whether the remaining number (remaining amount) of the pallets 12 placed on the tray placement stage 13 is small (ST6). If the supply-side lifter 20 is in the second state (see FIG. 9), the control unit 53 determines that the remaining number of pallets 12 is sufficient and returns to (ST1) described above.

  On the other hand, when the supply-side lifter 20 is in the third state (see FIG. 10), the control unit 53 determines that the remaining number of pallets 12 is small, and is then stored in the tray 5 supplied to the second position B2. It is determined whether the remaining number of remaining parts 3 is small (ST7). If the remaining number of parts is small, the control unit 53 returns to (ST1) and executes the same operation as described above. That is, here, all the components 3 are taken out from the tray 5 supplied to the second position B2, and the empty tray 5 (used tray 5A) is collected in the tray collection unit 8, and then the transfer arm. The lowering of the supply side lifter 20 is suspended until the operation of taking out the tray 5 at the tray taking-out position A1 by 41 is executed. The reference value for determining that the remaining number of parts is small is arbitrarily set by the worker.

  On the other hand, when the number of remaining parts is sufficient, the control unit 53 lowers the supply side lifter 20 (ST8) (arrow e in FIG. 16). Then, the control unit 53 determines whether or not the tray mounting stage 13 is located at the tray replenishment position A2, that is, whether or not the supply side lifter 20 is in the first state (ST9). Is stopped at the timing when is positioned at the tray replenishment position A2 (ST10) (see FIG. 16). Here, the tray mounting stage 13 is moved to the tray until the remaining number of parts 3 stored in the tray 5 supplied to the second position B2 is reduced (until it is determined that the remaining part number is small in (ST7)). Wait at the replenishment position A2. In this way, while the tray placement stage 13 is lowered to the tray replenishment position A2, the operator operates the supply side door opening / closing request switch 46 to open the supply side door 44 and perform the replenishment operation of the tray 5. .

  When the pallet 12 is empty in (ST5), the control unit 53 generates a warning sound to notify the pallet replenishment (ST11), and then lowers the supply side lifter 20 (ST12). Then, the control unit 53 determines whether or not the tray placement stage 13 is positioned at the tray replenishment position A2 in the process of lowering the supply side lifter 20 (ST13), and stops descending at the timing when it is positioned at the tray replenishment position A2. (ST14). Thereafter, the above-described tray replenishment operation is performed by an operator.

  As described above, in the present embodiment, when the tray remaining amount detecting means detects that the remaining amount of the tray 5 on the tray mounting stage 13 has decreased, the tray 5 ( The tray placement stage 13 is moved to the tray replenishment position A2 except for the timing at which the pallet 12) removal operation is executed. Therefore, it is possible to suppress the occurrence of the waiting time for lowering the tray mounting stage 13 for the worker, and to greatly improve the efficiency of the tray replenishment work.

  Next, the operation of the collection side lifter 40 will be described in detail with reference to FIG. The operation described below is executed based on a collection-side lifter control program stored in advance in the component mounting device 4. First, the control unit 53 determines the light receiving state of the second light receiving unit U3 (ST15). Here, when the second light receiving unit U3 is ON, the control unit 53 lowers the collection side lifter 40 by one pallet (ST16).

  On the other hand, when the second light receiving unit U3 is OFF, the control unit 53 raises the collection side lifter 40 (ST17). Then, the control unit 53 determines the light receiving state of the second light receiving unit U3 in the process of raising the collection side lifter 40 (ST18), and the collection side lifter 40 is raised at the timing when the second light receiving unit U3 is turned on. And the collection side lifter 40 is lowered by one pallet from the stop position (ST19).

  Next, the control unit 53 monitors the light receiving state of the second light receiving unit U3 in this state (ST20), and when the pallet 12 is transferred by the transfer arm 41 and the second light receiving unit U3 is turned on. Then, the collection side lifter 40 is lowered by one pallet (ST21). Next, the control unit 53 determines whether or not the pallet 12 placed on the tray collection stage 33 is full based on the monitoring state by the lifter state monitoring unit 58 (ST22). That is, when the collection side lifter 40 is in the seventh state (see FIG. 11), it is determined that the pallet 12 is full.

  Here, when the pallet 12 is not full, the control unit 53 determines whether or not there is a sufficient margin for collecting the pallet 12 (ST23). That is, when the collection-side lifter 40 is in the fifth state (see FIG. 9), the control unit 53 determines that there is a sufficient margin for collecting the pallet 12 and returns to the above-described (ST20). On the other hand, when the collection-side lifter 40 is in the sixth state (see FIG. 10), the control unit 53 determines that there is only a small margin for collecting the pallet 12, and then the tray supplied to the second position B2. It is determined whether the remaining number of parts 3 stored in 5 is small (ST24).

  Here, when the number of remaining parts is small, the control unit 53 returns to (ST20) and thereafter performs the same operation. That is, here, all the components 3 are taken out from the tray 5 supplied to the second position B2, and the pallet 12 holding the empty tray 5 (used tray 5A) is taken out by the transfer arm 41. The lowering of the collection-side lifter 40 is suspended until the collection operation of being transferred onto the tray collection stage 33 is executed at the used tray transfer position D1.

  On the other hand, when the number of remaining parts is sufficient, the control unit 53 lowers the collection side lifter 40 (ST25) (arrow f in FIG. 16). Then, the control unit 53 determines whether or not the tray collection stage 33 is located at the tray collection position D2, that is, whether or not the collection side lifter 40 is in the eighth state (ST26). The descent is stopped at the timing positioned at the position D2 (ST27) (see FIG. 16). Here, the tray collection stage 33 is recovered to the tray until the remaining number of parts 3 stored in the tray 5 supplied to the second position B2 is reduced (until it is determined that the remaining number of parts is small in (ST24)). Wait at position D2. In this way, while the tray collection stage 33 is lowered to the tray collection position D2, the operator operates the collection side door opening / closing request switch 47 to open the collection side door 45, and collects the used tray 5A. Do.

  When the pallet 12 is full in (ST22), the control unit 53 generates a warning sound to notify the pallet collection (ST28), and then lowers the collection side lifter 40 (ST29). Then, the controller 53 determines whether or not the tray collection stage 33 is located at the tray collection position D2 in the process of lowering the collection side lifter 40 (ST30), and stops the descent at the timing when it is located at the tray collection position D2. (ST31). Thereafter, the above-described tray collection operation is performed by an operator.

  As described above, in the present embodiment, when the used tray amount detection unit detects that the remaining amount of the used tray 5A on the tray collection stage 33 has increased, it is used by the tray transfer unit. The tray collection stage 33 is moved to the tray collection position D2 except for the timing when the collected tray 5A is collected. Therefore, it is possible to suppress the occurrence of the waiting time for lowering the tray collection stage 33 for the worker, and to greatly improve the efficiency of the tray collection work. Needless to say, an operator sets the tray amount as a reference for lowering the tray mounting stage 13 (tray collection stage 33), and arranges the detection sensor at a position corresponding to the tray amount.

  Next, lock / unlock of the supply side door 44 or the collection side door 45 will be described with reference to FIG. The operation described below is executed based on a door opening / closing program stored in advance in the component mounting device 4. In addition, since the operation flow in each door is common, the collection side door 45 will be described by limiting to the supply side door 44 unless special explanation is required.

  When the supply side door opening / closing request switch 46 is pressed by an operator, a door opening / closing program is executed. First, the control unit 53 determines whether the supply side door 44 is locked by the supply side door lock mechanism 48 (ST32). When the supply side door 44 is in the unlocked state, the control unit 53 locks the supply side door 44 (ST33) and starts the operation of the supply side lifter 20 based on the supply side lifter control program (ST34). Note that the tray replenishment operation or the tray collection operation by the worker is performed when the supply side door 44 or the collection side door 45 is unlocked.

  On the other hand, when the supply-side door 44 is in the locked state in (ST32), the control unit 53 determines whether or not the driving of the pallet transfer mechanism 43 is stopped, that is, the transfer arm 41 transfers or takes out the pallet 12. It is determined whether or not the operation is stopped (whether or not the transfer operation of the pallet 12 holding the used tray 5A by the transfer arm 41 is stopped in the collection side door 45) (ST35). . When the driving of the pallet transfer mechanism 43 is stopped, the control unit 53 ends the operation of the supply side lifter 20 based on the supply side lifter control program (ST36).

  Next, the control unit 53 determines whether or not the tray mounting stage 13 is positioned at the tray replenishment position A2 (ST37). Here, when the tray mounting stage 13 is not located at the tray replenishing position A2, the supply side lifter 20 is lowered (ST38). Then, the control unit 53 determines whether or not the tray mounting stage 13 is positioned at the tray replenishing position A2 in the process of lowering the supply side lifter 20 (ST39), and the timing when the tray mounting stage 13 is positioned at the position. To stop the descent (ST40).

  Next, if the tray placement stage 13 is lowered to the tray replenishment position A2, the control unit 53 unlocks the supply side door 44 (ST41), and then releases the lock by generating a warning sound. A notification to this effect is made (ST42). When the tray placement stage 13 is located at the tray replenishment position A2 in (ST37), the control unit 53 executes the unlocking of (ST41), and then executes the unlocking notification of (ST42). To do.

  As described above, according to the present invention, in the state in which the tray remaining amount detecting means detects that the remaining amount of the tray 5 of the tray mounting stage 13 has decreased, the tray 5 by the tray transfer means. The tray placement stage 13 is moved to the tray replenishment position A2 except for the timing when the take-out operation is executed. As a result, it is possible to eliminate the waiting time for lowering the tray mounting stage 13 during the tray replenishment operation, and to greatly improve the convenience for workers. As a result, the efficiency of the tray 5 replenishment operation can be increased and the productivity can be improved.

  When the used tray amount detection unit detects that the amount of the used tray 5A on the tray collection stage 33 has increased, the operation of collecting the used tray 5A by the tray transfer unit is executed. The tray collection stage 33 is moved to the tray collection position except for the timing. Thereby, the waiting time for lowering the tray collection stage 33 during the tray collection operation can be eliminated, and the convenience for the worker can be greatly improved. As a result, the efficiency of collecting the tray 5 can be increased.

  Since the tray mounting stage 13 rises in a direction away from the tray replenishment position A2 every time the stacked trays 5 are taken out, the present invention has a more remarkable effect on the tray mounting stage 13 side.

  In this embodiment, the tray supply unit 6 and the tray collection unit 8 are arranged on both sides of the first table 22 (first transfer unit) and the second table 26 (second transfer unit), respectively. By adopting such a layout, the component supply device 1 can be made compact and the efficiency of the tray supply operation can be improved.

  Further, the present invention is not limited to the embodiments described so far. For example, a moving mechanism for moving the transfer arm 41 in the Y direction may be newly provided, and the tray 5 may be transferred to the first table 22 or the second table 26 located at the second position B2. Further, the mounting head 51 is moved to above the tray 5 transferred to the first table 22 or the second table 26 located at the first position B1, and the component 3 is taken out from the tray 5 and mounted on the substrate 2. You may do it. Furthermore, instead of the first table 22 and the second table 26, one table on which the tray 5 taken out from the tray supply unit 6 is transferred is provided, and the component 3 is taken out from the tray 5 on the table by the mounting head 51. You may do it. In this case, the transfer arm 41 functions as a tray transfer unit that takes out the uppermost tray 5 at the tray extraction position A1 and transfers it to the mounting work position by the component mounting unit.

  According to the present invention, during the tray replenishment (collection) operation, it is possible to eliminate the waiting time for the worker while the tray mounting (collection) stage is lowered to the tray replenishment (collection) position, and components are mounted on the board. This is useful in the field of component mounting.
