[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment according to a component mounting apparatus and a component mounting method of the present invention will be described with reference to the drawings.
[0018]
Here, the feature of the present invention is that a plurality of suction nozzles 24 (see FIG. 10) are mounted on a plurality of mounting heads 7 and 8 as shown in FIG. In a component mounting apparatus and a component mounting method that are sequentially mounted on mounting locations on a printed circuit board, apart from automatic mounting operations, for example, a sufficient number of component supply points in a prototype line or the like cannot be secured, and setting of components on the apparatus is not possible. Corresponding to special applications where the setup work required for setting the components is complicated, manual mounting of such components (the operator directly sucks the component 15 by the suction nozzle 24, The normal component automatic mounting) operation has been made possible.
[0019]
The external configuration of the component mounting apparatus main body is the same as that shown in FIG. 1, and the same reference numerals are given to avoid redundant description, and description thereof is omitted. However, the configuration that is the feature of the present invention is detailed. As will be described later, in addition to the automatic mounting operation during normal production operation, a setting menu for enabling manual mounting operation corresponding to the above-described special application is added. Then, as shown in FIG. 8, the automatic mounting operation program and the manual mounting operation program stored in the storage means (RAM 30, ROM 31, etc.) are selected on the display screen of the display means (CRT 33), and on the setting screen. The control means (CPU 32) has a function of executing an automatic mounting operation or a manual mounting operation based on the set contents.
[0020]
Hereinafter, the setting menu will be described while describing various circuit configurations shown in FIG.
[0021]
First, an “initial screen” is displayed on the touch panel screen attached on the screen of the CRT 33 mounted on the component mounting apparatus main body (see FIG. 2).
[0022]
In this “initial screen”, operation touch keys for “production operation”, “setup operation”, “data editing”, “apparatus maintenance”, and “environment setting” are prepared. Then, for example, if an operation touch key “production operation” is touched on this screen, the production operation is started and the automatic mounting operation is executed.
[0023]
Further, the “data editing” operation touch key on the “initial screen” is touched to display the “data editing” screen (see FIG. 3).
[0024]
On this “Data Edit” screen, “Pattern Program”, “Device Setting Data”, “Operation Parameter”, “Offset Data”, “Test Operation Data”, “Part Library Data”, “Nozzle Arrangement Data”, “ The operation touch keys “nozzle type data” and “nozzle manual specification data” are displayed. Select the data to be edited on this screen.
[0025]
Here, the setting of various data related to the mounting work will be described. By touching the operation touch key of “Pattern Program” on the “Data Edit” screen, the “Pattern Program” screen is displayed (not shown). In this case, there are touch keys for displaying an input screen of “mounting data” as shown in FIG. In FIG. 4, mounting data relating to mounting work has already been input. In this mounting data, for each mounting step, what type (in which tape feeder (FDR)) of the component 15 is mounted on the printed circuit board 18 where (coordinate X, Y) and in what direction (angle Z). It is data indicating that.
[0026]
Here, the FDR numbers 101 to 110 are component-installed FDR numbers that actually exist in the apparatus, and numbers less than 100 are fictitious FDR numbers that do not exist in the apparatus. Therefore, in the mounting data shown in FIG. 4, FDR: 001 and FDR: 002 of step numbers (P-NO) 0004 and 0005 are the fictitious FDR numbers and data indicating that it is a hand-compatible component described later. Become.
[0027]
In addition, a touch key for displaying an input screen for “component arrangement data” as shown in FIG. 5 is present in the “pattern program” screen. In FIG. 5, data relating to component placement has already been input. The component arrangement data is associated with the mounting data and is data indicating what component (component ID) is to be installed at each FDR number (within each tape feeder) in the mounting data.
[0028]
Further, a touch key for displaying an input screen for “component library data” as shown in FIG. 6 exists in the screen of the “pattern program”. In FIG. 6, data related to the parts library has already been input. This part library data is data for setting various data details such as the characteristics of each part (for example, part dimensions, part thickness), handling speed, recognition data, and used nozzles. Component handling control, component recognition, etc. are executed.
[0029]
These various data are stored in the RAM 30 or ROM 31 as storage means shown in FIG. In FIG. 8, 32 is a CPU as a control means, 36 is an I / O, and the RAM 31, ROM 32, CPU 32, CRT 33, drive circuit 34, buzzer 35, etc. are connected via the I / O 36.
[0030]
The operation will be described below.
[0031]
After the various setup operations by the operator are completed, an automatic start operation by the component mounting apparatus 1 is started by pressing a “start” button (not shown) on the apparatus side. That is, in the order of the mounting steps input in the mounting data, component suction (removal of the component 15 in the component supply device 16 by the suction nozzle 24), component recognition (presence / absence of components sucked by the suction nozzle 24 by the recognition camera 21) , Recognition of posture, etc.), component position correction (position correction in the mounting direction (angle Z) taking the recognition result into account), and component mounting (mounted at specified coordinate (X, Y) position on printed circuit board 18 at angle Z) ) Is repeated.
[0032]
The feeder part actually installed in the apparatus 1 is determined based on whether or not it is an actual FDR number. With the above-described mounting data, automatic mounting operation is performed from mounting steps 0001 to 0003. When the process of FDR number 001 is entered, it shifts to manual mounting operation.
[0033]
Hereinafter, the flow of transition from the automatic mounting operation to the manual mounting operation will be described with reference to an operation flowchart shown in FIG.
[0034]
First, in FIG. 9, when the production operation is started, the step counter is initialized and the step counter is incremented by “1”.
[0035]
Subsequently, the FDR number in the mounting data is checked to determine whether or not the FDR number is an actual number. In this case, since it is the mounting step 0001, it is an existing FDR number, and the production operation is executed according to the following.
[0036]
That is, the desired mounting head (suction nozzle 14) moves to the position of the tape feeder in the component feeder 16 that stores the feeder (FDR) component of the corresponding FDR number, and the desired component 15 is sucked at that position. To do.
[0037]
Next, the suction nozzle 14 that sucks the component 15 moves onto the recognition camera 21, and recognizes the presence / absence, posture, etc. of the component 15 there.
[0038]
Further, based on the recognition result, the suction nozzle 14 is driven to X, Y, Z (rotation) via the drive circuit 34, and the posture of the component 15 is corrected according to the mounting location.
[0039]
Subsequently, the component 15 is mounted at a mounting location on the printed circuit board 18.
[0040]
Then, it is determined whether or not the control command C is E (end). In this case, since it is not E (end), the process proceeds to the next mounting step 0002.
[0041]
Similarly, when the mounting operation up to the mounting step 0003 is completed, the mounting operation of the mounting step 0004 is started. The mounting operation of the mounting step 0004 corresponds to an aerial FDR number, which is a feature of the present invention as described above. Naturally, the determination result of the FDR number is determined to be an aerial one.
[0042]
Therefore, unlike the operation description so far, the operation is shifted to the following operation. That is, the mounting head (suction nozzle 14) is moved to the hand position, and the suction nozzle 14 stops moving while maintaining the vacuum suction state at that position. It should be noted that the handing position may be a place where the parts can be easily handed by an operator. For example, an intermediate position between the adjacent parts supplying devices 16 may be considered.
[0043]
Then, the operator manually attaches the desired component 15 to the suction nozzle 14 that is standing by at the handing position. At this time, the “production operation” screen is switched to a “parts manual mode” screen which is a manual execution guide as shown in FIG.
[0044]
Therefore, the operator uses the mounting head 7 (head (1) side) of the A beam 3 displayed on the component 15 corresponding to the manual display (component ID: QFP 304) displayed on the screen of the “component manual mode”. It is made to adsorb | suck to the nozzle 24. When the manual suction is completed, the “complete” touch key on the screen is touched, and then the “start” button on the apparatus side is pressed to restart.
[0045]
As described above, in this embodiment, the manual execution guidance is displayed on the screen to prompt the operator to perform the manual mounting work. However, for example, the manual mounting work may be executed by voice guidance or the like.
[0046]
After that, as described above, the suction nozzle 14 that sucks the component 15 moves onto the recognition camera 21 and recognizes the presence, posture, etc. of the component 15 there.
[0047]
Further, based on the recognition result, the suction nozzle 14 is driven to X, Y, Z (rotation) via the drive circuit 34, and the posture of the component 15 is corrected according to the mounting location.
[0048]
Subsequently, the component 15 is mounted at a mounting location on the printed circuit board 18.
[0049]
Then, it is determined whether or not the control command C is E (end). In this case, since it is not E (end), the process proceeds to the next mounting step 0005.
[0050]
Thereafter, the automatic mounting operation or the manual mounting operation is executed in the same manner, and the component mounting operation by the component mounting apparatus 1 is completed in the mounting step 0007 in which the control command C becomes E (end).
[0051]
Hereinafter, the operation of each component of the component mounting apparatus 1 shown in FIG. 1 in the component mounting operation will be described. First, the printed circuit board 18 is transported to the work table position by the transport conveyor 20, and is positioned and fixed by the fixing mechanism.
[0052]
Subsequently, the mounting heads 7 and 8 move XY to the electronic component take-out position of the desired component supply device 16, where they are lowered to the upper surface of the electronic component 15 and suck the electronic component 15 with the tip of the suction nozzle 24. To do. In addition, although the said component supply apparatus 16 introduces as an example the component supply apparatus of what is called a tape cassette feeder system which accommodates an electronic component in a tape, the tray feeder system of mounting an electronic component on what is called a tray. It may be a component supply device or a stick feeder type component supply device in which an electronic component is housed in a stick.
[0053]
Then, the mounting heads 7 and 8 are raised again, and the electronic component 15 is sucked and held at the tip of the suction nozzle 24 and moved XY above the component recognition camera 21, where the mounting heads 7 and 8 (suction) Recognize the position of suction position deviation and the state of component drop with respect to the nozzle 24).
[0054]
In the following, the description will be continued assuming that there is no abnormality, but if an abnormality is found, it will be dealt with according to the abnormality situation. That is, for example, if the suction position deviation is abnormal, the electronic component 15 is ejected and then returned to the suction work again. If the part drop abnormality is abnormal, for example, it may be controlled to return immediately to the suction work. . Further, the apparatus may be stopped abnormally and the operator may be notified of the abnormality via the buzzer 35 or the like.
[0055]
Hereinafter, the description will be continued assuming that there is no abnormality, but the mounting heads 7 and 8 move XY to the desired electrode pads (adhesive, solder, etc. are applied in advance) of the printed circuit board 18 and descend there. The electronic component 15 is mounted on the electrode pad. Thereafter, after the above operation is repeated, each electronic component 15 is connected to the printed circuit board 18 by reflowing the solder.
[0056]
In this embodiment, the so-called XY robot type component mounting apparatus in which the mounting heads 7 and 8 that have attracted the electronic component 15 to the mounting location on the printed board 18 move in the XY manner has been described. The present invention may also be applied to a so-called rotary table type component mounting apparatus in which a plurality of mounting heads are installed radially on the back surface of a possible turntable.
[0057]
【The invention's effect】
According to the present invention, in response to special applications, the component take-out nozzle is moved to a desired position, and the movement of the component take-out nozzle is stopped until the component is applied to the component take-out nozzle at that position, and the component is manually attached. In addition, it has a control unit that moves the component pick-up nozzle and performs manual mounting to mount the component on the mounting board. The control unit enables manual mounting operation corresponding to special applications apart from automatic mounting operation. As a result, it has been difficult to set up parts due to the difficulty of setting parts, and the setup time required for setting parts occupies a large weight, resulting in very low efficiency. The problem can be solved.
[0058]
In particular, even in the case of a short taping component or the like that does not secure a tape length that can be loaded into a feeder in a prototype line, it is possible to operate the apparatus by providing a manual mounting environment.
[0059]
In addition, when the number of finished substrates is as small as one or several, and loss due to setup work for setting taping parts in the equipment becomes a problem, it is possible to improve work efficiency by intentionally selecting manual mounting. .
[0060]
Furthermore, the application range of the component mounting apparatus is widened because two operation modes, an automatic mounting operation mode and a manual mounting operation mode, which have never existed before can be mixed.
[0061]
In addition, in the present invention, apart from automatic mounting operation on the screen of the display means for displaying various operation screens , the component removal nozzle is moved to a desired position corresponding to a special application, and the component is moved to the component removal nozzle at that position. Stops the movement of the component removal nozzle until it is manually attached, moves the component removal nozzle where the component is manually attached , displays a setting screen that enables manual mounting operation to mount the component on the mounting board, and displays the setting screen. The manual mounting operation can be executed based on the simple setting operation.
[0062]
Further, when performing the manual mounting operation, the manual execution guide is displayed on the screen of the display means, and the operator can perform the manual mounting according to the instruction on the display screen.
