Description

  The present invention relates to an electronic component manual mounting machine used when an operator manually mounts electronic components on a mounting board.

  As a device for manually mounting components on a conventional mounting board, a positioning unit for positioning the mounting board, a supply device for preparing components necessary for mounting, and a take-out position display indicating a component take-out position in the supply device There is a hand-mounted device including a device and a control device that controls a position display device and a supply device according to a mounting program (see, for example, Patent Document 1).

  FIG. 8 is a perspective view showing a schematic configuration of the hand-mounted device described in Patent Document 1. In FIG.

  In FIG. 8, a mounting board 801 is placed on a mounting board cradle 802, and a component supply unit 803 that is first taken out by the mounting program moves up and down with respect to a position closest to the operator. To do. When the position closest to the worker is reached, the lid of the component supply unit 803 is opened, and the position indicator lamp 804 that displays the component removal position to the worker is lit.

An operator takes out a component from the component supply unit 803 instructed by lighting and performs manual mounting. After this mounting operation is repeated for a predetermined number of parts, the manual mounting operation for one mounting board is completed.
JP 60-217700 A (FIG. 1)

  However, in the configuration of the conventional manual mounting apparatus, the supply of parts is not uniform and the supply is only in one direction constrained by the packaging of the parts. For this reason, in order to correspond to a mounting board having various mounting component angles to be mounted, it is necessary for an operator to perform a component change operation using both hands in order to adjust the mounting angle.

  For this reason, in the case of components that are mounted in a plurality of directions, it is necessary for the operator to pay attention to the mounting direction in order to prevent the mounting direction from being incorrect or the mounting direction from being incorrect. It had the problem that.

  The present invention solves the above-described conventional problems, eliminates the need for the operator to change parts in the mounting direction, prevents mistakes in the mounting direction, and realizes a reduction in mounting time. It is an object of the present invention to provide an electronic component manual mounting machine capable of achieving the above.

  To achieve the above object, an electronic component manual mounting machine according to the present invention supplies a taped electronic component and is capable of changing a component supply angle, and a plurality of cassette-type component supplies. Depending on the installation position of the cassette type component supply device, the component supply installation unit to which the device is attached, the substrate positioning unit that positions and holds the mounting substrate on which the electronic component is mounted, And a control unit for changing the component supply angle. The taped electronic components can be supplied one by one in a direction suitable for manual mounting on the mounting board.

  According to the electronic component manual mounting machine of the present invention, it is possible to prevent an error in the mounting direction in manual mounting by an operator and to shorten the mounting time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall configuration diagram of an electronic component manual mounting machine according to an embodiment of the present invention as seen from a planar state. In the following description, the same components as those described in FIG. 8 are denoted by the same reference numerals, and the description thereof is omitted.

  In FIG. 1, a plurality of cassette type component supply apparatuses 101 are installed at a plurality of component supply positions 103 in a component supply installation unit 102, and a mounting board 801 to be mounted is installed in a substrate positioning unit 104. In this example, the component supply position 103 is provided with POS3 to -3 on the left and right sides with the reference position POS0 interposed therebetween.

  Further, in FIG. 1, the component rotation direction 105 of the cassette type component supply device 101 is the same as the electronic component mounting direction 106 of the mounting substrate 801 to be mounted, and each component supply in which the cassette type component supply device 101 is installed. The relative position between the position 103 and the mounting substrate 801 in the substrate positioning unit 104 indicates that the correction angle (θ1) 107 is provided.

  Next, how to determine the correction angle 107 will be described.

  The following calculation methods and data are all stored in the control unit 108 such as a computer.

  First, as a reference in the electronic component manual mounting machine, the lower right position of the mounting board 801 in the board positioning unit 104 is set as a reference origin 109 in the XY directions. This is to prevent the reference from changing even if the size of the mounting substrate 801 is changed by using the lower right substrate when fixing the mounting substrate 801 as a reference.

  In this electronic component manual mounting machine, as shown by the coordinates in FIG. 1, the direction from the reference origin 109 to the right is the positive direction of the X axis, and the direction from the board positioning unit 104 to the component supply installation unit 102 is The positive direction of the Y axis. With respect to the rotation angle, the Y-axis 110 is defined as 0 degree, and the counterclockwise direction is defined as the plus direction.

  Next, the substrate reference position 112 is obtained from the length (K_x) 111 of the mounting substrate 801 in the substrate X direction. The substrate reference position 112 is a position of (X, Y) = (− K_x / 2, 0).

  Next, a relative angle (θpos) 114 from the substrate reference position 112 to the component rotation center position 113 of each cassette type component supply apparatus 101 is obtained.

  The Y-direction distance (PY) 115 between the component rotation center position 113 and the board reference position 112 is common to all the component supply positions 103, and the X-direction distance (PXpos) 116 differs for each component supply position 103. .

  The pos0X direction distance (PX0) 117 between the component rotation center position 113 and the substrate reference position 112 in the cassette type component supply apparatus 101 in which the component supply position 103 is at the position POS0 takes into consideration the maximum dimension of the target mounting substrate 801. The component supply position (POS) 103 is set by the supply pitch (PPX) 118.

The X-direction distance (PXpos) 116 when the component supply position 103 shown in FIG. 1 is POS2 is calculated by Expression (1).
PX2 = (K_x / 2) −PX0 + PPX * 2 (1)
When the component supply position 103 is defined by POS-3 to 3 as shown in FIG. 1 using pos as a variable, Expression (1) is expressed by Expression (2).
PXpos = (K_x / 2) −PX0 + PPX * pos (2)
Therefore, the relative angle (θpos) 114 at the component supply position 103 is expressed by Expression (3).
θpos = tan ⁻¹ (PXpos / PY) (3)
The relative angle (θpos) 114 indicates that the component supply position 103 increases in the plus direction as it goes to the left from the board reference position 112 and increases in the minus direction as it goes to the right.

  Based on the information of the relative angle (θpos) 114, the correction angle 107 for correcting the rotation direction is obtained as follows.

θpos ≧ 40 degrees ⇒ Correction angle: 30 degrees 40 degrees> θpos ≧ 25 degrees ⇒ Correction angle: 15 degrees 25 degrees> θpos ≧ −25 degrees ⇒ Correction angle: 0 degrees−25 degrees> θpos ≧ −40 degrees ⇒ Correction angle: −15 degrees−40 degrees> θpos → correction angle: −30 degrees The correction angle is added to the electronic component mounting direction 106 of the mounting board 801 to be mounted, and a corrected rotation angle 119 that is an actual rotation angle is determined. .

  The fixed value of each said formula in this case is shown below.

K_x = 330mm
PX0 = 140mm
PY = 320mm
PPX = 100mm
Electronic component mounting direction = 90 degrees The corrected rotation angle of each component supply position 103 is as follows.

POS θpos Correction angle Corrected rotation angle −3 40.6 degrees 30 degrees 90 + 30 = 120 degrees −2 28.6 degrees 15 degrees 90 + 15 = 105 degrees −1 13.2 degrees 0 degrees 90+ 0 = 90 degrees 0 −4.7 Degree 0 degree 90+ 0 = 90 degree 1 -21.3 degree 0 degree 90+ 0 = 90 degree 2-35.1 degree -15 degree 90-15 = 75 degree 3 -45.4 degree -30 degree 90-30 = 60 The data of the degree relative angle (θpos) 114 is stored in the control device 108 and is automatically corrected when the component supply position 103 is changed. Therefore, the operator does not need to be aware of the correction angle (θ1) 107.

  In this example, four types of correction angles 107 of −30 degrees, −15 degrees, 15 degrees, and 30 degrees are used. However, if the correction angle 107 exceeds ± 30 degrees, an adverse effect that it is mistaken for the adjacent angle occurs.

  As a result, it is possible to reduce work time loss that occurs when the component supply position 103 of the cassette type component supply apparatus 101 is away from the mounting substrate 801 to be mounted.

  Further, in this example, the substrate reference position 112 of the relative angle (θpos) 114 is one place in the center of the substrate, but two reference points may be provided for the right arm and the left arm depending on the operator.

  In addition, although the determination is based only on the relative angle (θpos) 114, the determination may be based on only the X-direction distance (PXpos) 116, or may be determination using both the distance and angle calculations.

  Further, regarding the calculation of the relative angle (θpos) 114, it is effective to give worker information and change the corrected rotation angle 119 according to the height of the worker.

  Specifically, in the case of an operator who is lower than the standard height, a constant value is subtracted from the Y-direction distance (PY) 115, the angle correction is started earlier to increase the correction angle, and the operator is higher than the standard height. In the case of, set the opposite.

  That is, in general, a worker with a short height has a short arm and the distance from the base of the arm to the fingertip is short (the distance from the fulcrum is small). A tall worker has a long arm, and the distance from the base of the arm to the fingertip is long (the distance from the fulcrum is large). It is possible to insert a part corresponding to the height of the body.

  This will be specifically described with reference to the drawings. FIG. 2 is an explanatory view of the difference in angle correction due to the difference in height of the worker, FIG. 2 (a) is an explanatory view showing the relationship between the worker with a short height and the parts supply, and FIG. 2 (b) is the height of the worker. It is explanatory drawing which shows the relationship between a high worker and component supply.

  As shown in FIG. 2 (a), as described above, a worker with a short height has a short arm and needs to increase the rotation of the component at the component removal position. To be larger. On the other hand, a tall worker has a long arm, and as described above, the rotation of the component at the component removal position may be small. Accordingly, the angle correction is delayed and the rotation angle is decreased correspondingly.

  In this example, the standard height is 1600 mm, and the Y-direction distance (PY) 115 is changed by 50 mm every time the height changes by 50 mm.

  Furthermore, since a plurality of cassette-type component supply devices 101 can be installed in the component supply / installation section 102, a plurality of cassette-type component supply devices 101 can be used side by side in accordance with a plurality of types of mounting boards 801. A configuration in which the cassette-type component supply device 101 can be attached to and detached from the component supply installation unit 102 and can be replaced by being removed and inserted when changing the component to be used in accordance with the model change of the substrate 801. By doing so, it can be applied to usage methods with many model changes.

  When using a model whose length in the board X direction (K_x) 111 is changed, by automatically making it possible to follow the corrected rotation angle 119, it is possible to easily perform an operation according to the mounting board to be used. Can do.

  Next, the cassette type component supply apparatus in this embodiment will be described.

  FIG. 3A is a plan view of the cassette type component supply device in the present embodiment, and FIG. 3B is a side view of the cassette type component supply device in the present embodiment.

  In FIG. 3A, a plurality of taped electronic components 201 are mounted on the cassette type component supply device 101. The taped electronic component 201 is sent by a fixed amount in one direction by the guide unit 202, and is cut from the taping by the cutting unit 203 as shown in FIG.

  The electronic component 204 separated by cutting is lifted from the taping height 206 by the lifting portion 205, and as shown in FIG. 3A, the component rotation center position 113 is set together with the lifting portion 205 by the rotation positioning motor 207. As a reference, it rotates in the rotational direction shown in FIG.

  With such a configuration, the separated electronic component 204 can be rotated and positioned at an arbitrary position and supplied.

  The cassette type component supply apparatus 101 is provided with a display lamp 208, which can be turned on / off by a control device.

  Next, the installation angle in this embodiment will be described.

  FIG. 4 is a side view of the electronic component manual mounting machine according to the present embodiment.

  The cassette-type component supply apparatus 101 is attached with a tilt angle 302 from the mounting substrate 801 placed on the substrate positioning unit 104 and the substrate installation upper surface 301 by the component supply installation unit 102. This is because by tilting the parts, the separated electronic parts 204 can be easily taken out, the distance for moving the parts is shortened, and the working time is shortened.

  Although the tilt angle 302 is 20 degrees in this example, it is effective if it is in the range of 10 degrees to 35 degrees.

  Next, the usage method of the electronic component manual mounting machine in this embodiment is demonstrated.

  FIG. 5 is an explanatory diagram of a control program in the present embodiment.

  As shown in FIG. 5, the control unit 108 of the electronic component manual mounting machine stores a control program 401 corresponding to the type of mounting board to be used. Specifically, the control program 401 stores data such as a mounting order 403, a worker's hand 404 used during mounting, a mounting position 405, a mounting angle 406, a take-out position 407, and a display image 408 for each mounting component 402. Has been.

  FIG. 6 is a flowchart of the operation steps in the electronic component manual mounting machine of this embodiment, and FIG. 7 is an explanatory diagram showing an operation example in the electronic component manual mounting machine of this embodiment.

  Hereinafter, with reference to FIGS. 5 to 7, the operation of each part and the work of the operator by the control unit in the electronic component manual mounting machine will be described.

  The operator selects the control program 401 suitable for the mounting board 801 to be used, starts the operation of the mounting machine, and sets the mounting board 801 in the board positioning unit 104 as shown in FIG.

  When the mounting board 801 is set, according to the mounting order 403 of the control program 401, the cassette-type component supply device 101 designated at the take-out position 407 supplies the separated electronic component 204 in accordance with the mounting angle 406, The display lamp 208 is turned on (step S1).

  The other cassette-type component supply device 101 to be used on the control program 401 starts the operation of supplying the separated electronic component 204 at an angle that matches the mounting angle 406.

  Further, the display device 501 displays a display image 408 on the mounting board 801 in accordance with the control program 401 in accordance with the mounting angle 406 on the mounting position 405 (step S2).

  The operator takes out the separated electronic component 204 according to the display lamp 208 and manually mounts the electronic component 204 on the mounting substrate 801 at a predetermined position at a predetermined position according to the display image 408.

  In the cassette type component supply apparatus 101 to be extracted, when the presence / absence of a component sensor (not shown) as a removal sensor detects that a component has been removed by an operator (step S3), the display lamp 208 is turned off. (Step S4).

  The control unit 108 determines whether or not the extracted component is the last component on the selected mounting board 801 (step S5). If it is not the last (NO in step S5), the next cassette to be extracted is determined. The display lamp 208 of the mold part supply apparatus 101 is turned on (step S6), so that the operator can know which part should be taken out next.

  Further, if it is not the last part (NO in step S5), the display device 501 turns off the display image 408 after a certain period of time after the part presence / absence sensor detects that the part has been taken out. Then, the display image 408 to be mounted next is displayed as a mounting angle 406 at a predetermined mounting position 405 (step S7).

  The predetermined time until the light is turned off can be changed by the control unit 108. In this example, the initial value is 2 seconds. However, if the presence / absence of a component is detected by the presence or absence of the next separated electronic component 204 before 2 seconds elapses, the display device 501 immediately displays the display image 408 of the mounting position 405 and the mounting angle 406. To do.

  When the last component to be mounted is taken out and the display image 408 is turned off (step S8), the control unit 108 sounds a buzzer (not shown) for a certain period of time to confirm that the mounting work necessary for production is completed. Inform.

  The control unit 108 controls each unit so that the mounting substrate 801 is continuously mounted and produced. When the control unit 108 detects that a component has been taken out by the presence / absence of the component, the cassette-type component supply device prepares for the next production. 101 is instructed to supply the separated electronic component 105.

  In this example, a projector is used as the display device 501, but a laser pointer may be used.

  As described above, according to the present embodiment, the operator can perform a mounting operation with no error in the mounting direction and with a shorter mounting time.

  Next, in this embodiment, an operation example when the worker is skilled will be described with reference to FIG. FIG. 8 is an explanatory view showing an operation example for a skilled person in the electronic component manual mounting machine of the present embodiment.

  In order to further shorten the work time, it is required that a worker simultaneously mounts a plurality of parts using both hands. This is made possible by eliminating the need to change parts.

  In this case, a plurality of supply locations and a plurality of mounting locations are generated, and there is a possibility that an operator may mistake which component is mounted on which mounting location.

  Therefore, in the display lamp 208 of the cassette type component supply apparatus 101, the display lighting 508 is different from the display lighting 503, and the display image 408 on the mounting board 801 is also different from the display lighting 504 and the display flashing 505. The display state is set so that the operator can determine which component is to be mounted and which location.

  Information on lighting / flashing is stored in the control program 401 shown in FIG. 5 as information on the hand 404 to be used (right hand, left hand).

  In this example, the blinking cycle is 0.5 second, and if the lighting cycle is too short or too long, it is difficult to distinguish the lighting state from the lighting state.

  Further, in this example, lighting and blinking are distinguished, but it is also possible to change the colors of both the display lamp 208 and the display image 408, or to display by combining lighting, blinking, and different colors.

  With such a configuration, it is possible to prevent a mounting error of a skilled person who performs mounting with both hands.

  The control unit 108 has a function for checking the removal time and the removal status of each part for each operator or board type, and a function for issuing an error when the required number of parts is not taken out. The error prevention function can be strengthened.

  The electronic component manual mounting machine of the present invention has the effect of shortening the mounting time and preventing the mounting direction error in the electronic component manual mounting machine. It can also be used for mistake prevention.
