Component Mounting Device {COMPONENT MOUNTING APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component mounting apparatus for supplying components, such as electronic components, from a component supply unit and mounting them on a substrate.

As a conventional component mounting apparatus, there exists a technique of patent document 1, for example. This technique performs the exchange of a tape feeder for each feeder bank, and here, a plurality of tape feeders are collectively replaced using a batch exchange carriage.

16 is a perspective view showing the component mounting portion 101A of the conventional component mounting apparatus 101. 17 is a perspective view showing a part of the setting position M1 of the collective replacement carriage 102A and the component mounting portion 101A in the conventional component mounting apparatus 101.

The component supply unit 102 is detachably attached to 101A.

In use, the collective replacement carriage 102 is inserted in the setting position M1. At this time, the base of the collective replacement carriage 102 is disposed between the fixed plate 171 of the component mounting portion 101A and the rising movable plate 172.

[Patent Document 1] Japanese Patent Laid-Open No. 2000-244183

However, in the component mounting apparatus described in Patent Document 1, since the connector is only automatically connected when the feeder bank 122 is raised, there is a possibility of connecting or disconnecting the connector by mistake while the power switch is in the ON state. In this case, it is sufficient for the safety of the device because the life of the contact is shortened due to the occurrence of ARC at the connector contact, or the circuit failure is caused by the influence of voltage fluctuation due to chattering at the time of contact. I could not say.

Accordingly, the present invention has been made in view of the above-described circumstances, and provides a component mounting apparatus having a component supply unit capable of automatically turning on / off a power switch at an appropriate timing, and to improve safety.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, the component mounting apparatus which concerns on Claim 1 is equipped with the component mounting part and the component supply part which can be attached or detached from the predetermined setting position of the component mounting part, and the component supplied from the said component supply part is located in the predetermined position on a board | substrate. A component mounting apparatus to be mounted, the component mounting portion being provided in the component mounting portion and holding a part of the component supply portion to fix the component supply portion at a predetermined working position to perform component supply, and the component supply portion. A connector for connecting a power supply line for supplying electric power to the component supply unit, a connector installed on the gripper and connected to the connector when the component supply unit is gripped; To perform connection and disconnection between the connector and the connected device in a state where the power supply is stopped. A power supply control means for controlling a supply source, an actuator for holding the component supply unit mounted at the setting position by the holding member, and then moving the component supply unit to move to the working position; Detecting means for detecting that the position is set at a position, wherein the power supply control means supplies the power supply source to perform power supply when the detecting means detects that the component supply portion is set at the working position. It is characterized by controlling.

As described above, since the connection and disconnection between the connector and the connected device are performed while the power supply is stopped, the lifetime of the contact is shortened due to the occurrence of an arc at the connector contact or the voltage due to chattering at the time of contact. It is possible to prevent the occurrence of circuit failure due to the influence of the fluctuation.

In addition, since power supply can be automatically started after connecting the connector and the connected device, it is necessary to perform an operation (such as turning on the power switch) for the operator to start supplying power after connecting the connector and the connected device. There is no.

That is, when setting the component supply part to the component mounting part, the component supply part is gripped by the holding body at the setting position to connect the connector and the connected device, and then the actuator is brought into an operating state to move the component supply part to the working position. The power supply is started as the component supply unit detects that the work position has been set. Therefore, the connector and the connected device can be connected without being necessarily energized, and power supply can be started after the connector and the connected device are connected.

In addition, in the case of separating the component supply part from the component mounting part, when the component supply part is moved from the working position toward the setting position, the power supply is automatically stopped, and then the connector is separated by separating the component supply part and the gripper at the setting position. And the connection between the connected device are released. In this way, since the power supply is automatically stopped, it is possible to prevent the operator from forgetting to turn off the power supply. In addition, it is possible to perform disconnection between the connector and the connected device in a state where power is not necessarily applied.

Further, in the component mounting apparatus according to claim 2, in the invention according to claim 1, the power supply control unit detects that the component supply unit is set to the working position by the detection unit after the actuator starts operation. When the power supply is controlled, the power supply is controlled.

In this way, since the condition of starting the power supply is to detect that the parts supply part is set at the work position by the detection means after the operation of the actuator, the detection means detects an object other than the parts supply part at the working position. It is possible to reliably prevent an incorrect power supply due to detection.

Further, the component mounting apparatus according to claim 3 includes a component mounting portion and a component supply portion detachable from a predetermined setting position of the component mounting portion, and the component mounting apparatus for mounting the component supplied from the component supply portion at a predetermined position on a substrate. And a gripping member which is installed in the component mounting part and holds the part supply part by holding a part of the part supply part to fix the part supply part at a predetermined working position to perform part supply, and is installed in the part supply part. A connector for connecting a power supply line for supplying electric power to the gripper, the connector to be connected to the connector when the component supply unit is held, and the connection and connection between the connector and the connected device. Power supply control means for controlling a power supply source to perform a release in a state in which the power supply is stopped; And an actuator for holding the component supply unit mounted at the setting position by the holding member, and then moving the component supply unit to move to the working position by detecting the connection state between the connector and the connected device. And a detection means, wherein said power supply control means controls said power supply source to perform electric power supply when it is detected by said connection state detection means that said connector and said connected device are in a connected state, after starting operation of said actuator. Characterized in that.

As a result, when setting the component supply part to the component mounting part, when the component supply part is gripped by the gripper at the setting position and the connector and the connected device are connected, the power supply is started after detecting this. Therefore, the connector and the connected device can be connected without being necessarily energized, and power supply can be started after the connector and the connected device are connected.

In addition, in the case where the parts supply part is separated from the parts mounting part, when the actuator is stopped to move the parts supply part from the work position toward the setting position, the power supply is automatically stopped, and then the parts are removed from the setting position. By separating the supply portion and the gripper, the connection between the connector and the connected object is released. In this way, since the power supply is automatically stopped, it is possible to prevent the operator from forgetting to shut off the power supply, and thereby to disconnect the connection between the connector and the connected device without being energized.

Further, in the component mounting apparatus according to claim 4, in the invention according to claim 3, the power supply control means detects that the connector and the connected device are in a connected state by the connection state detecting means after the actuator starts operation. And after a predetermined time, the power supply is controlled to start power supply.

As a result, when setting the component supply part to the component mounting part, it is possible to reliably provide a delay time between connecting the connector and the connected device and starting the power supply. Therefore, the safety at the time of connecting between a connector and a to-be-connected can be improved.

In the component mounting apparatus according to claim 5, in the invention according to any one of claims 1 to 4, any one of the connector and the connected device is directed upward, and the other connection port is downward. And a movable cover which covers the upper surface of the one connecting port when the parts supply part is separated from the parts mounting part, and is opened and closed according to the detachment of the parts supply part to the parts mounting part. It is characterized by.

In this way, when the component supply portion is separated from the component mounting portion, the cover covers the upper surface of the connection port, whereby foreign matters can be prevented from falling into the connection port. Therefore, it is possible to prevent the occurrence of a short or the like due to the connection between the connector and the connected device in a state where foreign matter falls to the connection port and is left unattended.

Furthermore, since the cover is opened and closed in accordance with the attachment and detachment of the component supply section to the component mounting section, when the component supply section is mounted, the cover can be opened to prevent the cover from interfering with the connector connection and at the same time, the component supply section At the time of separation, the cover is in a closed state, and foreign matter falls on the connector.

According to the present invention, since the connection and disconnection between the connector and the connected device are performed in a state in which the power supply is stopped, the life of the contact is shortened due to the occurrence of an arc at the connector contact, or by chattering at the time of contact. It is possible to prevent the occurrence of circuit failure due to the influence of voltage fluctuations, thereby ensuring safety. In addition, since the power supply is automatically started after the connector is connected to the connected device, an operation such as a power switch by an operator is unnecessary.

In this manner, a component mounting apparatus having improved safety can be realized.

As shown in FIG. At this time, as shown in FIG. 3, the feeder bank 22 presses and moves the cover 76 in the direction opposite to the direction which presses with the pressing member 76a, and the floating connector 29 and the connector 75 are moved. ) Is inserted to the opposite position.

In this insertion state, when the actuator 73 is operated with the lift switch 15 turned ON, the movable plate 72 is raised so that the upper surface of the movable plate 72 abuts against the lower surface of the base 23.

At this time, the positioning pin 72a of the movable plate 72 is inserted into the guide hole 23c of the base 23, and the floating connector 29 and the connector 75 are connected.

Then, as the movable plate 72 is raised to raise the feeder bank 22 along the guide shaft 21b, the positioning pin 23a of the base 23 is inserted into the guide hole 71a of the fixed plate 71. The base 23 is inserted and fixed between the fixed plate 71 and the movable plate 72.

In this way, the feeder bank 22 mounted at the setting position M1 is a working position for performing component supply by the actuator 73, that is, the upper surface of the base 23 is raised to abut the lower surface of the fixing plate 71. Raise to the upper limit position of the stroke. At this time, when the base 23 is gripped by the fixed plate 71 and the movable plate 72 at the setting position M1, the floating connector 29 and the connector 75 are automatically connected.

Here, the rising detection sensor 77 detects that the feeder bank 22 is set at the working position. When the feeder bank 22 is set at the working position, the ON signal and the feeder bank 22 are at the working position. Outputs OFF signal when not set at.

The AND circuit 41 inputs the ON / OFF signal of the rising switch 15 and the ON / OFF signal of the rising detection sensor 77 to output a signal for performing ON / OFF of the feeder bank power supply. That is, the feeder bank power supply is turned on when both the signals of the rising switch 15 and the rising detection sensor 77 are ON, and is turned OFF when at least one signal is OFF.

In addition, the component supply unit 2 corresponds to the component supply unit, the holding mechanism 7 corresponds to the holding body, the cable 34 corresponds to the power supply line, the floating connector 29 corresponds to the connector, Reference numeral 75 corresponds to the connected device, the rise detection sensor 77 corresponds to the detection means, and the AND circuit 41 corresponds to the power supply control means.

(action)

Next, the operation of the first embodiment will be described.

In the state in which the feeder bank 22 is not set in the component mounting part 1A of the component mounting apparatus 1, since the signals of the rising switch 15 and the rising detection sensor 77 are all OFF, feeder bank power supply is turned off. Is OFF. At this time, the upper surface of the connector 75 is covered with the cover 76 to prevent foreign matters and the like from falling on the connector 75.

In the case of setting the feeder bank 22 in this state, first, the batch replacement carriage 2A in which the tape feeder 3 is mounted on the feeder bank 22 is set to the setting position M1 of the component mounting portion 1A. ). At this time, by inserting the feeder bank 22, the cover 76 on the connector 75 is pressed to open the cover 76. Then, the feeder bank 22 is inserted to the position where the floating connector 29 faces the connector 75.

In this state, the worker turns ON the lift switch 15 at time t1 of FIG. 5 to raise and fix the feeder bank 22. At this time t1, the signal of the rising switch 15 turns ON, but the feeder bank 22 is not raised and fixed, and the rising detection sensor 77 does not detect the feeder bank 22. The signal of the rising detection sensor 77 maintains the OFF state. Therefore, the feeder bank power supply also remains OFF at time t1.

6 is a schematic diagram when the lift switch 15 is turned ON. As shown in FIG. 6, when the lift switch 15 is turned ON, the movable plate 72 is raised, and the positioning pin 72a of the movable plate 72 is inserted into the guide hole 23c of the base 23. At the same time, the floating connector 29 and the connector 75 are connected. The time of such a connector connection is t2. At this time, as shown in Figure 5, the floating connector 29 and the connector 75 is in a contact state, the signal of the rising detection sensor 77 maintains the OFF state, the feeder bank power also maintains the OFF state. .

Thereafter, when the movable plate 72 is raised while the floating connector 29 and the connector 75 are connected, as shown in FIG. 7, the positioning pin 23a of the base 23 is fixed to the stationary plate 71. The base 23 is inserted between the fixed plate 71 and the movable plate 72 to be inserted into the guide hole 71a of the (). At this time, the rising detection sensor 77 detects that the feeder bank 22 is raised and fixed. Let this time be t3. At time t3, both the signal of the rise switch 15 and the signal of the rise detection sensor 77 are turned on, so that the feeder bank power is switched to the ON state as shown in FIG.

In this way, the feeder bank power supply is turned ON under the condition that the rising switch 15 and the rising detection sensor 77 are both on. For this reason, the movable plate 72 is raised in a state where the feeder bank power supply is turned off, and the connector can be connected in a state where power is not necessarily supplied. At the time of ascending, the connector is connected during the rise of the feeder bank 22, and then the rise detection sensor 77 is turned on near the upper limit of the ascending stroke, so that the feeder bank power is turned on. The power can be turned ON.

At the time of lowering, the operator lowers the feeder bank 22 by turning off the rising switch 15. In this case, as shown in Fig. 8, when the rising switch 15 is turned off at time t11, the feeder bank power supply is turned off at the same time. Thereafter, as the movable plate 72 descends, the feeder bank 22 also descends, and the rising detection sensor 77 is turned off at time t12. And when the movable plate 72 further descends, the floating connector 29 and the connector 75 will be separated.

In this way, when the lowering switch 15 is turned off and the feeder bank power supply can be turned off, the connector can be disconnected without being energized.

In addition, when the floating replacement carriage 2 is pulled out from the setting position M1 of the component mounting portion 1A with the floating connector 29 and the connector 75 separated, the feeder bank for the cover 76 ( The pressing force of 22 is released, and the cover 76 returns to the position which covers the upper surface of the original connector 75 by the pressing member 76a as shown in FIG.

(effect)

As described above, in the first embodiment, since the connection and disconnection of the connector can be performed without necessarily energizing, arcing or the like can be prevented from occurring at the connector contact. In addition, since the circuit is not affected by voltage fluctuations due to chattering at the time of contact, stable operation can be provided.

In addition, since the power is automatically supplied to the feeder bank when the feeder bank is raised and fixed, the operation of the power switch by the operator is unnecessary, and the working time can be shortened.

In addition, since the supply of power to the feeder bank is automatically stopped when the feeder bank is lowered, it is possible to prevent the operator from forgetting to shut off the power supply, thereby ensuring safety.

In addition, since the cover is provided in the connector of the upward structure provided on the component mounting side, it is possible to prevent foreign matter from falling on the connector. For this reason, when a connector is connected in the state which a foreign material falls, the case where a short etc. generate | occur | produce can be prevented and safety can be ensured.

Furthermore, the cover is configured to automatically open and close when the collective replacement carriage 2A is attached or detached, thereby preventing the cover from interfering with the connector connection when the collective replacement carriage is attached. At the same time, it is possible to reliably prevent foreign matter from falling on the connector by closing the cover when the collective replacement carriage 2A is removed.

(2nd embodiment)

Next, a second embodiment of the present invention will be described.

In the second embodiment described above, in the first embodiment described above, the rising switch (r) is used to control the feeder bank power supply ON / OFF by using the signal of the rising switch 15 and the rising detection sensor 77. It is to control feeder bank power on / off by using 15) and connector connection status.

(Configuration)

FIG. 10: is a figure which shows typically the arrangement relationship of the feeder bank 22 and the holding mechanism 7 in 2nd Embodiment.

As shown in FIG. 10, the component mounting apparatus 1 of this embodiment is the structure which removed the rise detection sensor 77 shown in FIG.

In the present embodiment, similarly to the first embodiment described above, the feeder bank 22 is set in the component mounting portion 1A and the floating connector 29 and the connector 75 are connected, and then the power supply of the feeder bank 22 is supplied. Is configured to automatically turn on.

11 is a circuit diagram of a power supply control means for performing ON / OFF control of a feeder bank power supply.

The circuit for ON / OFF control of the feeder bank power supply is composed of an AND circuit 42, a delay circuit 43, and a feeder bank presence / absence detection circuit 44.

The ON / OFF signal of the rising switch 15 and the output signal of the delay circuit 43 are input to the AND circuit 42. The delay circuit 43 is a circuit which outputs the signal of the feeder bank presence detection circuit 44 with a predetermined delay time. Here, the feeder bank presence detection circuit 44 outputs a signal which is turned ON when the floating connector 29 and the connector 75 are connected, and turned off when the floating connector 29 and the connector 75 are not connected. It is a circuit to output the signal.

That is, the feeder bank power supply is turned on when the delay time elapses after the signal of the feeder bank presence detection circuit 44 is turned on when the rising switch 15 is turned on.

The AND circuit 42 and the delay circuit 43 correspond to the power supply control means, and the feeder bank presence / absence detection circuit 44 corresponds to the connection state detection means.

(action)

Next, the operation of the second embodiment will be described.

When setting the feeder bank 22 without setting the feeder bank 22 in the component mounting apparatus 1, first, the collective exchange carriage which mounted the new tape feeder 3 on the feeder bank 22 is carried out. Insert 2A into the setting position M1 of the component mounting apparatus 1. At this time, the cover 76 is opened by inserting the feeder bank 22 to open the cover 76. Then, the feeder bank 22 is inserted to the position where the floating connector 29 faces the connector 75. In this state, the worker turns ON the lift switch 15 to raise and fix the feeder bank 22.

At this time, since the floating connector 29 and the connector 75 are not connected as shown in FIG. 12, the signal (feeder bank presence / absence signal) of the feeder bank presence / absence detection circuit 44 does not have a feeder bank 22. As shown in FIG. OFF state is displayed. Therefore, when the time at which the rising switch 15 is turned ON is t21, the feeder bank power supply is kept in the OFF state at time t21 as shown in FIG.

Thereafter, when the movable plate 72 is raised to connect the floating connector 29 and the connector 75 at time t22, the feeder bank presence signal is switched to the ON state indicating that the feeder bank 22 is present. At this time, since the output signal of the feeder bank presence / absence detection circuit 44 is input to the AND circuit 42 through the delay circuit 43, the feeder bank power supply maintains an OFF state at the time t22.

Then, at time t23 when a predetermined delay time elapses from time t22, the output signal of the delay circuit 43 is turned on, and the feeder bank power supply is switched to the on state. The state diagram at this time is shown in FIG.

In this way, when the connector is connected while the feeder bank 22 is being raised, the feeder bank presence signal is turned on. Since the feeder bank presence signal is inputted to the AND circuit 42 through the delay circuit 43, the feeder bank power supply is turned on later after the feeder bank presence signal is turned on. Therefore, a connector connection is made in the state which is not necessarily energized, and power can be supplied after connector connection.

At the time of lowering, the operator lowers the feeder bank 22 by turning off the rising switch 15. In this case, as shown in Fig. 15, when the rising switch 15 is turned off at time t31, the feeder bank power supply is turned off at the same time. The state diagram at this time is as shown in FIG. After that, as the movable plate 72 descends, the feeder bank 22 also descends, and the coupling of the floating connector 29 and the connector 75 is released at time t32. At this time, feeder bank presence signal is turned off at the same time.

In this manner, when the lowering switch 15 is turned off and the feeder bank power supply can be turned off at the time of the lowering, the connector can be detached without necessarily energizing.

(effect)

As described above, in the second embodiment, like the first embodiment described above, the connector can be connected and disconnected in a state in which power is not necessarily supplied. It is also possible to automatically supply power to the feeder bank after connecting the connector.

At this time, since the signal of the rising switch and the signal of the feeder bank presence / absence detection circuit for detecting the connector connection state are used for the ON / OFF control of the feeder bank power supply, there is no need to provide a rise detection sensor as in the above-described first embodiment. . For this reason, the cost can be reduced and design freedom can be improved.

(Variation)

Further, in the first embodiment, the case where the ON / OFF control of the feeder bank power is performed using the signal of the rising switch 15 and the signal of the rising detection sensor 77 has been described, but the rising detection sensor 77 The ON / OFF control of the feeder bank power can also be performed using only the signal of. At this time, the feeder bank power may be turned ON when the rising detection sensor 77 is ON, and the feeder bank power may be turned OFF when the rising detection sensor 77 is OFF.

Even in this case, when the feeder bank is raised, the feeder bank power is turned ON when the floating connector 29 and the connector 75 are connected while the feeder bank 22 is further raised and fixed at the working position. When the feeder bank is lowered, the feeder bank power is turned off when the feeder bank 22 descends and is out of the working position. Then, after the feeder bank 22 is further lowered, the floating connector 29 and the connector ( 75) is released. In this way, the connector can be disconnected and connected without being necessarily energized.

In the second embodiment, a case has been described in which the output signal of the feeder bank presence / absence detection circuit 44 is input to the AND circuit 42 via the delay circuit 43, but the delay circuit 43 is omitted. You may. In this case, after the connector is connected and the feeder bank presence signal is turned on, the feeder bank power is turned on later due to the delay of the related circuit. Therefore, it can always be made energized late after connector connection. However, it goes without saying that a definite effect can be obtained when the delay circuit 42 which intentionally delays the feeder bank presence signal is provided.

Furthermore, in each of the above embodiments, the case where the movable cover 76 which protects the connector connection port from foreign matter is provided above the connection port of the connector 75 has been described, but the connection port of the floating connector 29 has been described. When facing upward and the connection port of the connector 75 is arranged downward, a movable cover having the same function as the cover 76 is provided above the connection port of the floating connector 29.
