Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component mounting apparatus which is applied to a mounting process of an electronic component such as a semiconductor chip on a substrate in a manufacturing process of an electronic circuit substrate.

[0002]

2. Description of the Related Art For example, in a process of manufacturing an electronic circuit board, a component mounting device applied to a process of mounting an electronic component such as a semiconductor chip on a substrate is a head for sucking a component supplied by a component supply device and the head. A device having a moving means for moving the head to a component mounting position and a controller for controlling the head and the moving means is generally adopted.

Here, the component mounting apparatus having the above-mentioned configuration will be briefly described. Generally, the component mounting apparatus performs a teaching operation (teaching) for creating operation data of the component mounting apparatus for mounting a component on a board. , Such as mounting step data, which is created based on this teaching operation, including mounting step number, mounting position data indicating the position on the board where the component should be mounted, and mounting component data indicating the type of the component to be mounted at that time. Reproduction operations such as component suction, discharge, and mounting are performed according to the teaching data.

Then, the regenerating operation of the component mounting apparatus by the controller is carried out according to the control flow chart shown in FIG. This reproducing operation will be described below for each control step of the control flowchart.

[Step B1] When the reproduction is started, the mounting step number is set to 1. [Step B2] The teaching data corresponding to the mounting step number is read. [Step B3] According to the mounted component data of the teaching data read in the above [Step B2], the head is moved by the moving means to the position of the predetermined mounted component on the component supply device. As a matter of course, each component is always supplied to a fixed position on the component supply device.

[Step B4] The suction operation of the specified mounted component is executed (described later). [Step B5] The head in the state of picking up the component is moved to the mounting position designated by the mounting position data of the mounting step data. [Step B6] A component mounting operation is executed (described later).

[Step B7] It is determined whether or not this mounting step number is a preset final mounting step number, and if the final mounting step number is determined, it is assumed that all the components have been mounted, which will be described later in [Step B9]. ] To proceed. If not, proceed to the next [Step B8]. [Step B8] The mounting step number is incremented by one, the process proceeds to [Step B2], and the above steps are repeated until the mounting step number matches the final mounting step number. [Step B9] The reproduction operation is ended.

Here, the component suction operation in the above [Step B4] is performed according to the control flow chart shown in FIG. The component suction operation will be described below for each control step of the control flowchart.

[Step B4-1] When the suction is not normally performed, the number of retries indicating the number of suction operations performed again is cleared (= 0). [Step B4-2] The suction nozzle provided on the head is lowered to a predetermined position. [Step B4-3] A vacuum pressure is generated to suck the component by the suction nozzle. [Step B4-4] The suction nozzle is raised. [Step B4-5] Check the vacuum pressure in the suction nozzle.

[Step B4-6] Above [Step B4
If the vacuum pressure checked in [-5] exceeds a predetermined value, it is determined that the suction is normally performed and the component suction operation is ended to proceed to [Step B4-10] described later. It is determined that the ink is not adsorbed on the sheet, and the process proceeds to the next [Step B4-7]. [Step B4-7] If it is determined in the above [Step B4-6] that the component is not normally sucked by the suction nozzle of the head, the component is not sucked by the suction nozzle at all or is not sucked. Although there is a possibility that it is not adsorbed in the normal direction, this [Step B4-7]
Then, the discharging operation is once executed (described later).

[Step B4-8] The number of retries is incremented by one. [Step B4-9] It is determined whether a retry error has occurred. That is, when the number of retries reaches a predetermined value, it is determined that a retry abnormality has occurred, and [Step B
4-11], on the other hand, if the number of retries does not reach the predetermined value set in advance, it is determined that there is no retry error, the process returns to the above [Step B4-2], and the steps from [Step B4-2] to [Step B4] are repeated. -9] until the number of retries matches a predetermined value, or [Step B
4-6] is repeated until the vacuum pressure becomes normal (parts are normally sucked).

[Step B4-10] The component suction operation is completed. [Step B4-11] If a retry error occurs, that is, if the parts cannot be normally picked up even if the picking operation is repeated a predetermined number of times, an alarm is generated as a part shortage or a part supply device error and the device is stopped.

Here, the parts discharging operation in the above [Step B4-7] is performed according to the control flow chart shown in FIG. The discharging operation will be described below for each control step of the control flowchart. In addition, the reference numerals indicating the respective control steps are shown in parentheses.

[Step B4-7-1] The head is moved to a component discharge position, which is provided in advance on the component mounting apparatus, for collecting components having abnormal suction. [Step B4-7-2] The suction nozzle provided on the head is lowered to a predetermined position. [Step B4-7-3] The generated vacuum pressure is broken (that is, increased) to eject the component.

[Step B4-7-4] The suction nozzle is raised to a predetermined position. [Step B4-7-5] The head is moved to a predetermined position of the component supply device where the same component as the ejected component is supplied. [Step B4-7-6] The parts discharging operation is ended.

On the other hand, the component mounting operation in [Step B6] described above is performed according to the control flowchart shown in FIG. The component mounting operation will be described below for each control step of the control flowchart. Note that, like the above, the reference numerals indicating the respective control steps in the drawing are described in ().

[Step B6-1] The suction nozzle provided on the head is lowered to a predetermined position. [Step B6-2] The generated vacuum pressure is broken (that is, increased) to separate the component from the suction nozzle. As a result, the component is mounted at the predetermined mounting position.

[Step B6-3] The suction nozzle is raised to a predetermined position. [Step B6-4] The component mounting operation is completed.

[0019]

As is apparent from the above-described operation, in the above component mounting apparatus, when the predetermined component to be sucked on the component supply apparatus is insufficient, an alarm is generated and the operator is notified. However, there is a problem in that the work is interrupted until the insufficient parts are confirmed and supplied and restarted, so that the apparatus is stopped by the setup and adjustment when the parts run out, resulting in a decrease in production efficiency.

Therefore, it is an object of the present invention to provide a component mounting device which does not stop production efficiency when the components run out.

[0021]

In order to achieve the above object, the component mounting apparatus of the present invention comprises a head for sucking a component supplied by a component supply device and a moving means for moving the head to a component mounting position. And a controller for controlling the head and the moving means, wherein the controller, when a predetermined component to be picked up on the component supply device is insufficient, other controller on the component supply device. Is picked up by the head and mounted at the corresponding component mounting position, and then, when the lacking component is supplied to the component feeder, the lacking component is sucked by the head and the corresponding component mounting is performed. It is characterized in that the head and the moving means are controlled so as to be mounted at a position.

[0022]

According to the component mounting apparatus of the present invention, when a predetermined component to be picked up on the component supply device is insufficient, for example, the type of the insufficient component is displayed and the component supply device is instructed by a command from the controller. The other components are picked up by the head and mounted at the corresponding component mounting positions. Then, when the missing component is supplied to the component supply device by the operator, for example, the missing component is sucked by the head and mounted on the corresponding component mounting position. Therefore, the operator does not stop the component mounting device even while the operator is preparing and supplying the insufficient component.

And mounting step data consisting of mounting part data indicating

Next, the reproducing operation of the component mounting device by the controller 4 will be described step by step with reference to the control flowcharts shown in FIGS. 4 and 5. 4 and 5 are a series of control flowcharts, and the lowermost a shown in FIG. 4 is connected to the uppermost a shown in FIG.

[Step A1] At the start of reproduction, the mounting step number is set to 1. [Step A2] The teaching data corresponding to the mounting step number is read.

[Step A3] [Step A5], which will be described later, which was executed before shifting to [Step A3].
[Steps A5, 17-11] of the component suction operation of FIG.
(Refer to be described later), although the suction operation is repeated a predetermined number of times, the component cannot be suctioned normally, and the stored abnormal data (consisting of the step number and the component data when the abnormality occurs). Of the mounting step data corresponding to the mounting step number at the time of shifting to [Step A3], and when these match (that is, they are the same part), The process proceeds to [Step A9] described below, and if not, the process proceeds to the next [Step A4]. That is,
If the component pick-up is abnormal even though it has been repeated a predetermined number of times in the component pick-up operation one control cycle before, this step number and the part data are stored as abnormal data, and the mounting corresponding to the mounting step number of the next control cycle. If the component data coincides with the component data of the above-mentioned suction abnormality, the movement of the nozzle head 2 to the component suction position, the component suction operation, the movement to the component mounting position, and the component mounting operation should not be performed in this control cycle [step. A
9] is skipped. Then, this skip is performed as long as the component data of the abnormal data and the mounted component data corresponding to the mounting step number of the control cycle match.

[Step A4] According to the mounting part data of the mounting step data read in the above [step A2], a predetermined position on the part supply device (tape feeder 5 or tray feeder 6, hereinafter the same) of a predetermined mounting part. Then, the nozzle head 2 is moved by the XY robot 3. As a matter of course, each component is always supplied to a fixed position on the component supplying device. [Step A5] The suction operation of the specified mounted component is executed (described later).

[Step A6] During the suction operation executed in the above [Step A5], [Step A5, 1
7-11] (see FIG. 6), if the abnormal data stored increases, the process proceeds to [Step A9] described below, and if not, the process proceeds to the next [Step A7]. That is, when the suction abnormality occurs during the suction operation (the abnormality data increases at this time), the movement of the nozzle head 2 to the component mounting position and the component mounting operation of this control cycle are performed. It skips to [Step A9] so that it does not exist. [Step A7] Nozzle head 2 with components picked up
Is moved by the XY robot 3 to the mounting position on the board designated by the mounting position data of the mounting step data.

[Step A8] A component mounting operation is executed (described later). [Step A9] It is judged whether or not the mounting step number of this control cycle is a preset final mounting step number, and if the final mounting step number, all parts (excluding the suction abnormal part) are mounted. As a matter of course, the process proceeds to [Step A11] described later. If not, proceed to the next [Step A10].

[Step A10] 1 for the mounting step number
The count is added and the process proceeds to the above [Step A2], and the above [Step A2] to [Step A10] are similarly repeated until the mounting step number matches the final mounting step number. As a result, the components excluding the suction-abnormal component are sequentially mounted at the predetermined positions on the board. [Step A11] [Step A5, 17-11] which will be described later during the suction operation executed in [Step A5] above.
If the abnormal data stored in (see FIG. 6) is stored, the process proceeds to the next [Step A12], and it is attempted to re-mount the component that was canceled due to the suction abnormality in the subsequent steps. Become. On the other hand, if the abnormality data is not stored, it is assumed that no component suction abnormality has occurred and all the components are mounted at predetermined positions, and the process proceeds to [Step A24] to be described later and the reproducing operation is ended.

[Step A12] Whether or not the operator has set a shortage component in the component supply device or replaced the component supply device with one in which the shortage component has been filled and returned (that is, the suction abnormality has occurred). Whether or not the parts that have been installed are in the parts supply device). Here, the controller 4 receives the input signal by an operator's button operation or the like or the detection signal by a sensor or the like to recover the component supply device. Then, if the component supply device has returned, the process proceeds to the next [Step A13], and if not, this [Step A12] is looped until the component supply device returns. [Step A13] The step number of the abnormal data stored in [Step A5, 17-11] of the component suction operation described later is newly set as the mounting step number. That is, the re-mounting operation and the like are started from the mounting step where the adsorption abnormality occurs.

[Step A14] The above [Step A1]
3] or the teaching data corresponding to the mounting step number set in [Step A21] described later is read. [Step A15] It is determined whether the mounted component data of the teaching data and the component data of the abnormal data match, and if they match, the process proceeds to the next [Step A16]. Step A20]. This is when the mounting component data of the mounting step number, which is sequentially incremented by one count in [Step A21] described later, matches the component data of the suction abnormality (that is, the mounting component data and the component of the suction abnormality according to the mounting step number order). (When the data are sequentially matched and they match)
Only, the procedure proceeds to the next [Step A16] to execute the mounting operation or the like, and if not, it is not necessary to perform the mounting operation or the like, and the procedure is skipped to [Step A20] described later.

[Step A16] Above [Step A1
4] The nozzle head 2 is moved by the XY robot 3 to the position of the component supply device for the designated mounted component in accordance with the mounted component data of the teaching data read in. [Step A17] The suction operation of the specified mounted component is executed (described later). [Step A18] The XY robot 3 moves the nozzle head 2 in the state of picking up the component to the mounting position on the substrate designated according to the mounting position data of the teaching data.

[Step A19] A component mounting operation is executed (described later). [Step A20] It is determined whether or not this mounting step number is a preset final mounting step number, and if it is the final mounting step number, all the components except the component in which the suction abnormality has occurred are mounted. Then, the process proceeds to [Step A22] described later. If not, proceed to the next [Step A21]. [Step A21] The mounting step number is incremented by 1 and the process proceeds to [Step A14].

[Step A22] Above [Step A1
4]-[Step A21] Clear the abnormal data corresponding to the parts that can be mounted. [Step A23] If there is still abnormal data other than the abnormal data cleared in the above [Step A22], that is, if there is a component that has become a suction abnormality again, return to the above [Step A13] and repeat the above [Step A13]. The process up to [Step A23] is repeated as long as there is abnormal data. [Step A24] The reproduction operation is ended.

[Step A5, 17-1] The number of retries indicating the number of suction operations performed again when the suction is not normally performed is cleared (= 0). [Step A5, 17-2] The suction nozzle 9 provided on the nozzle head 2 is lowered to a predetermined position. [Steps A5, 17-3] A vacuum pressure is generated to cause the suction nozzle 9 to suck the component.

[Step A5, 17-4] Suction nozzle 9
Is raised to a predetermined position. At this time, the chuck 11 provided on the nozzle head 2 positions the component with respect to the suction nozzle 9. [Step A5, 17-5] The vacuum pressure is checked by the vacuum sensor 28.

[Step A5, 17-6] If the vacuum pressure checked in [Step A5, 17-5] above exceeds a predetermined value, it is judged that the component is normally sucked, and the component suction operation is performed. It will be described later to finish the process [Step A
5, 17-13]. If not, it is determined that the component is not adsorbed normally, and the next [Step A5, 1]
7-7]. [Steps A5, 17-7] Above [Steps A5, 17-7]
When it is determined in [6] that the vacuum pressure is abnormal and the component is not normally sucked by the suction nozzle 9 of the nozzle head 2, the component is not sucked by the suction nozzle 9 at all or is suctioned. May not be picked up in the normal direction, so the component discharging operation is executed once in this [Step A5, 17-7] (described later).

[Step A5, 17-8] The number of retries is incremented by one. [Steps A5, 17-9] It is determined whether a retry error has occurred. That is, if the number of retries reaches a predetermined value, it is determined that a retry abnormality has occurred, and the process proceeds to the next [Step A5, 17-10]. On the other hand, if the number of retries does not reach a preset predetermined value, a retry abnormality occurs. If it is determined that it has not been performed, the above [Step A5, 17-
2] and repeat from [Step A5, 17-2] to [Step A5, 17-9] again until the number of retries agrees with a predetermined value or the adsorption is normally performed (the adsorption is normally performed. If performed, of course [Step A5, 17-6] to [Step A5, 17-1]
3])).

[Steps A5, 17-10] Abnormal Data Number It is judged whether or not there is an abnormality. That is, when the number of abnormal data matches a predetermined number set in advance, it is determined that the number of abnormal data is abnormal and an alarm is generated to proceed to [Step A5, 17-14] described later, and the number of abnormal data is If the number is less than the above-mentioned predetermined number, it is determined that the number of abnormal data is not abnormal, and the next [Step A5, 17-11].
Proceed to. [Step A5, 17-11] Abnormal data is stored.
That is, the mounting step number and component data when a component suction retry abnormality occurs are stored as abnormality data.

[Step A5, 17-12] In order to inform the operator that a component suction retry error has occurred, that is, a predetermined component of the component supply device has become insufficient, for example, a warning light is made to blink. Etc. generate warnings. In addition, the part number or the like of the part in which the retry error has occurred is displayed so that the operator can easily confirm what the abnormally supplied part is. [Steps A5, 17-13] The component suction operation ends. [Step A5, 17-14] Above [Step A5, 1
7-10], if the number of abnormal data reaches a predetermined number, an alarm is generated and the apparatus is stopped.

Here, the above [steps A5, 17-
7], the component discharging operation is performed according to the control flowchart shown in FIG. 7. The component discharging operation will be described below for each control step of the control flowchart.

[Step A5, 17-7-1] The nozzle head 2 is moved by the XY robot 3 to a component discharge position (not shown) provided in advance on the component mounting device for collecting components having abnormal suction. .. [Step A5, 17-7-2] The suction nozzle 9 provided on the nozzle head 2 is lowered to a predetermined position. [Step A5, 17-7-3] The generated vacuum pressure is broken (that is, increased) to separate the component from the tip of the suction nozzle 9.

[Step A5, 17-7-4] The suction nozzle 9 is raised to a predetermined position. [Step A5, 17-7-5] The nozzle head 2 is moved by the XY robot 3 to a predetermined position of the component supply device to which the same component as the ejected component is supplied. [Step A5, 17-7-6] The parts discharging operation is ended.

On the other hand, the component mounting operation of [Step A8] and [Step A19] described above is performed according to the control flow chart shown in FIG. The component mounting operation will be described below for each control step of the control flowchart.

[Steps A8, 19-1] The suction nozzle 9 provided on the nozzle head 2 is lowered to a predetermined position.
