The light is received by the light receiving sensor (46) without hitting (19) (hereinafter referred to as a light passing state). Although the light receiving sensor (46) received light due to the movement of the support base (39), the winding diameter is detected based on the position at which the light is no longer received, and the remaining number of parts is calculated as described below to notify the end of parts. It is something to do.

The motor (42) is a servo motor having a built-in encoder (56) that constantly detects the rotational position of the motor (42), and the position of the moving table (43) is determined by the rotational position detected by the encoder (56).

The arm (44) does not move even if the optical axis of the light emitting sensor (45) and the light receiving sensor (46) where the movable table (43) is at the origin position passes through the center of the tape reel (18). It is designed so as not to collide with the component supply device (7) including 18).

Reference numeral (57) is a tower lamp that visually informs the operator of the out-of-part or the like by lighting or blinking when giving a notice of out-of-part or the like.

In FIG. 5, reference numeral (48) is an interface connected to the CPU (49). Reference numeral (50) is a RAM as a storage device in which the NC data of each suction nozzle (12), parts library data and the like are stored. Reference numeral (51) is a ROM that stores a program relating to the mounting operation of the chip component (4).

Are connected. A substrate (not shown) including an interface (48) provided in the base (40) through the movable base (43) and the support base (39) from the sensors (45) (46) and the encoder (56). The connection line is routed to.

The drive circuit (54) drives the sensor movement motor (42), the component supply servomotor (8), the X-axis servomotor (2) and the Y-axis servomotor (3).

Each of the data stored in the RAM (50) will be described.

As shown in FIG. 9, the NC data indicates the mounting position (X coordinate data, Y coordinate data) on the printed circuit board (5) and the mounting direction for each step indicating the mounting sequence of the component (4). The mounting angle data shown and the reel number indicating the position on the supply table (6) where the component supply device (7) for supplying the chip component (4) are arranged are stored. The control command "E" indicates the end of the step.

In the component arrangement data, the component type (hereinafter referred to as “type”) supplied by the component supply device (7) for each reel number is stored as shown in FIG.

As shown in FIG. 11, the parts library data is shown in FIG. 6 and FIG. 8, the part thickness indicating the thickness of the part (4) and the external dimensions (X size, Y size) for each part type. Such a thickness of the tape (19) (tape thickness), the pitch of the chip parts (4) accommodated in the tape (19) (the accommodating chamber (36) and the feed hole (37) as shown in FIG. 7). ), The radius of the tape reel core (core radius), and the like are stored.

The tape (19) is loaded on the tape reel (18) in a state of being wound around the core (55) as shown in FIG. 6, and the radius of the core (55) is shown in FIG. In this case, it is indicated by "RS". The radius of the core (55) varies depending on the manufacturer of the tape and varies depending on the type of chip component (4) due to different materials.

In FIG. 6, the radius of the winding diameter of the tape (19) is “RV”, the tape thickness is “T” as shown in FIG. 8, and the pitch is “P” as shown in FIG. If "Q" is the number of loaded parts, "Q" can be obtained by approximation using the following calculation formula.

[0034]

[Equation 1]

“A” indicates the number of times the tape (19) is wound (the number of layers of the tape (19) which are overlapped), and is a natural number equal to or smaller than “(RV−RS) / T”. It is the largest number. The calculation formula is stored in the ROM (51), and the remaining component number "Q" is calculated from "RV" detected by the component outage detection sensor (52) and data corresponding to the component type in the component library data. It is a thing. To detect "RV", the movable table (43) moves from the origin position side to the right side in FIG. 1 and the light receiving sensor (46) detects the position of the change point from the light-shielded state to the light-transmitted state. The position at which the light receiving sensor (52) is at the center of the tape reel (18) (which is also the center of the core (55)), that is, the distance from the origin position may be set to "RV". The moving base (43) may move to the left side in FIG. 1 to detect the position where the light receiving sensor (52) shifts from the light passing state to the light blocking state.

In the RAM (50), a tact time memory for storing a tact time, which is a time required to mount the chip component (4) on one printed circuit board (5) currently mounted, and a currently mounted component. A mounted component number memory for storing the number of components used for one sheet for each component type used on the board (5) is provided for each type.

The takt time may be stored for each substrate type, and the measured real time may be stored, or may be set for each substrate.

When the tact time of the tact time memory is multiplied by a value obtained by dividing the remaining number of parts “Q” of the part supply device (7) by the value stored in the mounted part number memory, the printed circuit board (5) is mounted. However, it is possible to calculate the time when the component runs out, and the calculation formula is also stored in the ROM (51).

Further, the RAM (50) is provided with a remaining number counter that stores the remaining number of parts for each reel number (that is, for each component supply device (7)) and decrements by one each time a component is taken out. There is. The value of the counter is stored when the new remaining component number is calculated by the detection of the component shortage detection device (17).

The detection operation by the component shortage detection device (17) is performed when the chip component (4) is taken out for each step number of NC data after performing the setup change for changing the type of the printed circuit board (5). It is assumed that this is done before and when the component supply device (7) is replenished with the component (4). For the component supply device (7) with the reel number that has once been detected, When taking out (4), the detection operation is not performed. In order to determine whether the moving table (43) has once moved to detect the remaining number of parts, a detected memory is provided in the RAM (50) for each reel number to indicate whether or not it is detected. If the reel number of which the detection has been completed is set to the detected state, the CPU (49) checks the state of the memory for each step number to perform the detecting operation only for the one which is not in the detected state. be able to.

Further, the detection operation by the component shortage detection device (17) is performed by all the component supply devices (7) mounted on the supply base (6) after the power is turned on and before the component is mounted on the printed board. ) May be performed in order, or when all the component supply devices (7) are sequentially changed at the time of setup change accompanying the change of the type of the board (5) (before the mounting operation for each step number of NC data). It may be performed. Furthermore, the operation may be performed at any time, or may be performed each time the part (4) having the step number of all NC data is taken out. Further, it may be performed at a certain time each time the mounting of one component on the board (5) is completed.

The CRT (53) screen displays a notice of parts shortage, and the time of the parts shortage for giving the notice is also stored in the RAM (50). The time can also be set and changed.

With the above-mentioned configuration, the operation will be described below.

First, when the printed circuit board (5) is placed on the XY table (1), the component supply table (6) is moved by the drive of the component supply section servomotor (8), and the step number of the NC data is transferred. The component supply device (7) for supplying the product type "R1" arranged on the reel number "001" of "1" is on standby at the suction station (I). At the same time when the print substrate (5) is placed, the CPU (49) starts measuring the takt time.

At this time, the movable table (43) is stopped at the origin position where the sensors (45) and (46) pass through the center of the tape reel (18).

Next, the CPU (49) confirms that the detected memory of the reel number “001” is not in the detected state, the movable table (43) moves to the right side of FIG. 1, and the sensor (46), that is, the sensor. It is assumed that the position of the change point of (52) from the light-shielded state to the light-transmitted state is detected by the encoder (56), and the radius of the winding diameter of the tape (19) is detected as “RV1”. The CPU (49) calculates the remaining component number "Q1" by the following calculation based on the data of FIG. 11 corresponding to the product type "R1" and the detected "RV1" according to the program of the ROM (51).

[0047]

[Equation 2]

“A1” indicates the number of times the tape (19) is wound, and is the maximum number of natural numbers smaller than “(RV1-RS1) / T 1”. The calculated remaining number “Q1” is stored in the remaining number counter of the reel number “001”.

Next, when the movement of the movable table (43) is completed, the elevating rod (22) descends and the swing lever (21) swings counterclockwise in FIG. 3 to transfer the transmission lever (23). The sprocket (27) is rotated by a certain amount via the feed lever (24), the feed claw (25) and the feed gear (26), and the tape (19) is fed through the feed hole (37) with which the sprocket (27) meshes. Is sent by the pitch "P1", and the chip component (4) to be taken out next in the storage chamber (36) is supplied to the suction position of the suction nozzle (12). Further, when the movement table (43) finishes detecting the position of the change point, it moves to the left side of FIG. 1 and returns to the origin position, and the detected memory of the reel number "001" is set to the detected state.

Next, the suction nozzle (12) sucks the component (4) and moves to the recognition station (II) by rotating the turntable (11). In the recognition station (II), the recognition device (14) recognizes the component (4) sucked by the nozzle (12).

Next, the suction nozzle (12) of the recognizing device (14) is set to the mounting angle “θ1” shown in the NC data by the rotating roller (15) in the nozzle rotation correction station (III). The angular positioning is performed by correcting the angular displacement caused by the recognition result and rotating. When the component (4) is picked up, the remaining number counter is decremented by "1".

Next, the suction nozzle (12) reaches the mounting station (IV) by intermittent rotation of the turntable (11), and the XY table (1) is moved to the position determined by the recognition device (14). The chip component (4) is mounted by moving after correcting the displacement and lowering the suction nozzle (12) to the position (X1, Y1) indicated by the NC data of the printed circuit board (5).

On the other hand, when the suction nozzle (12) sucks the component (4) with the step number “001” in the NC data, the supply base (6) supplies the component (4) with the step number “002”, so that the reel is used. The component supply device (7) with the number "002" moves so as to reach the component suction position, but when the component supply device (7) reaches the component suction position and stops in the same manner as described above, the same operation as described above is performed. It is confirmed that the detected memory is not in the detected state, and the movable table (43) moves from the origin position to the right side in FIG. 1 to detect the position of the change point from the light-shielded state to the light-transmitting state. In this case, assuming that "RV2" is calculated, the data and the data of the parts library data of the part type "R2" of the reel number "002" are applied to the above-described calculation formula to calculate the remaining number of parts "Q2". The calculated memory is stored in the remaining number counter of the reel number “002”, and the detected memory is set to the detected state.

Next, the chip component (4) is sucked by the suction nozzle (12) from the component supply device (7) of the reel number “002”, and in the same manner as in the case of step number “001”, the print substrate ( The chip component (4) is mounted at the position (X2, Y2) of 5). The remaining number counter of the reel number "002" also becomes "Q2-1" by subtracting "1" from "Q2" when the suction nozzle (12) takes out the component (4).

The above operation is repeated to perform the suction and mounting operation of the chip component (4), but each time the reel number is the first one on the first board (5), the moving table (43 ), The remaining parts number is calculated and stored in the remaining number counter of the reel number, and the chip parts (4) are supplied from the parts number supply device (7) for which the remaining parts number has already been calculated. Is taken out, the counter is decremented. The detected memory of the component supply device (7) of the reel number (for example, the one of the reel numbers “001” and “002”) whose reel number has been detected by moving the moving table (43) once Has already been detected, the detection operation by the moving base (43) is not performed the next time the parts are supplied.

In this way, when the component mounting of one board (5) is completed and the next printed board (5) is placed on the XY table (1), the CPU (49) sets the takt time. After the measurement is completed, the measured time is stored in the takt time memory. When one board (5) is finished, the remaining number of parts is stored in the remaining number counter for all reel numbers of the parts (4) used for the board (5).

Further, in the present embodiment, the movement of the movable table (43) is completed during the stop time of the normal supply table (6) and does not affect the tact time. If it is not possible to move from the origin to the change point for detection during the stop time of (6), take a longer stop time of the supply base (6) and subtract the longer time from the measured takt time. The normal tact time may be set or the tact time of the second substrate (5) may be measured.

Next, components are similarly mounted on the second board, and the subtraction counter decrements by “1” each time a component is taken out, and the remaining component count is divided by the mounted component count memory each time. The value is multiplied by the takt time in the takt time memory to calculate the time until the parts run out. In this way, the components are mounted on the second and subsequent printed circuit boards (5), and the components calculated by the value of the remaining component counter of the component supply device (7) of a certain reel number (for example, "001"). When the time until the product runs out becomes less than the time (for example, 30 minutes) for which the part outage notice stored in the RAM (50) is reached, the part outage is announced on the screen of the CRT (53) as shown in FIG. At the same time, a tower lamp (57) lights up to warn, and a buzzer (not shown) emits an intermittent sound to give an audible warning.

Next, while the worker is not replenishing the part (4) with the reel number “001”, the time until the part runs out due to the remaining number of parts (4) with the reel number “003” is When the CPU (49) determines that the time is shorter than the time for giving a notice of parts exhaustion as described above, and the CPU (49) judges that the reel number "003" is also given to the CRT (53), a notice is given to the CRT (53). The screen 53) is displayed as shown in FIG. The display of the remaining time of CRT (53) changes with the passage of time.

After this, the worker loads a new tape (19) on the tape reel (18) to replenish the chip parts (4) of the parts supply device (7) with reel numbers “001” and “003”. However, when this loading is completed, the remaining number of parts is detected by moving the moving table (43) when the chip part (4) is taken out from the reel number next time. To detect the remaining number of parts after the parts are replenished, a key for notifying the CPU (49) that the parts (4) has been replenished is provided in the operation unit, the reel number is designated, and the key is pressed. By doing so, the detected memory provided in the RAM (50) may be brought into a state indicating that the detection has not been completed. Alternatively, if it is desired to detect the remaining number of parts regardless of whether they have been replenished, the reel number may be designated and detection may be performed.

The calculation formula used to calculate the remaining number of parts in this embodiment calculates the remaining number of only the portion wound on the tape reel (18). It is also possible to add the number of chip parts (4) between the position where it is pulled out from the tool (18) and sucked by the suction nozzle (12) to calculate the remaining number of parts. If it is possible to make a correction by actually counting that the actual number of remaining parts is different, then use the corrected calculation formula. In addition, this calculation formula uses the tape thickness as the part library data and uses this value.However, even if it does not have the tape thickness data, the part thickness data in the part library data can be used to obtain a predetermined value for the part thickness data. (Add data for each type of tape if necessary for each type of tape) may be used as the tape thickness.

Further, although the detection device (17) is fixed to the component suction position on the base (40), the reel (18) of the component supply device (7) can be checked by moving the supply base (6). It may be fixed on the base (40) at any position (may be a plurality of positions), or provided so as to be movable in the same direction as the moving direction of the supply base (6) with respect to the base (40). Good. In the component mounting device that picks up the component from the component supply device by moving the suction head without moving the supply table (6), the device corresponding to the detection device (17) can be moved in the direction of arrangement of the component supply device. However, in this case, the suction head may be provided with a device corresponding to the detection device (17).

Further, the detection device (17) may be attached to the component supply device (7) itself, or may be provided at all positions of the supply table (6) where the component supply device is attached.

Further, in the present embodiment, the number of the supply bases (6) is only one, but a plurality of supply bases which are independently movable in the arrangement direction of the component supply device (7) are provided. In the case of the component mounting device, after the components of the component supply device (7) are replenished (including the replacement operation) at the standby position of each supply table, or the replacement of the component supply device (7) for setup change is performed. While the other supply base is performing the component mounting operation according to the NC data after performing the above, the remaining number of components is detected by the detection device (17) fixed at an appropriate position on the base (40). You may make it operate | move.

In addition, without using the “RS” which is the radius of the core (55) to calculate the remaining number of components from the detected winding diameter, the winding diameter when the component (4) is full is calculated as part library data. Then, store the total number of chip parts (4) in the full state, and calculate the number of parts that have already been used from the value obtained by subtracting the winding diameter "RV" detected from the winding diameter in the full state. The remaining number of parts may be calculated by subtracting the number of used parts from the total number of full parts.

Furthermore, the winding diameter is first measured and then the predetermined operation is performed at the beginning of the component mounting operation or when the component supply device (7) is replaced without using the tape thickness or the component storage pitch. After the time (excluding the time of stop due to an abnormality, etc.) has elapsed (for example, after mounting one board or a predetermined number of boards), the winding diameter is measured again, and the plane of the tape reel in FIG. May be calculated to calculate the time when the remaining area excluding the area of the core (55) is finished, or the number of extracted parts (4) may be stored instead of the time. The number may be calculated.

Further, in the present embodiment, the advance notice of the component shortage is given according to the time when the component shortage occurs, but it is also possible to give the advance notice of the component shortage if the remaining number of components reaches a predetermined number.

Further, the display as shown in FIG. 12 may be called up at any time.
