[Problems to be solved by the invention]
However, the invention described in the above-mentioned Patent Document 1 is for coping with the vertical and horizontal deviations of the mounting surface, and is not intended to account for the amount of deviation generated in the vertical direction (direction perpendicular to the mounting surface). There wasn't.
In addition, if a distance measuring sensor is used instead of the image pickup means, it is possible to cope with the vertical displacement, but even in that case, the electronic component holding head is moved up and down with respect to all the electronic component supply cassettes on the mounting table. For example, if the mounting base is displaced farther than the specified position, the movement distance increases for all electronic component supply cassettes, which reduces the work efficiency and drives the head. There was also a problem of increasing the burden on the means.
[0005]
The present invention provides a mounting position adjusting device for an electronic component mounting device that eliminates the disadvantages of the above-described conventional example, suppresses a decrease in work efficiency of the electronic component holding head, and can reduce the influence of vertical displacement of the mounting base. Its purpose is to provide.
[0006]
[Means for Solving the Problems]
According to the first aspect of the present invention, a plurality of electronic component supply cassettes each having a reel on one end side in the longitudinal direction are placed side by side in a direction perpendicular to the longitudinal direction when viewed from above, and the reels of each electronic component supply cassette are The mounting base for placing the opposite end toward the main body is detachable from the main body, and the mounting base is clamped between the mounting base and the mounting base by applying pressure to the main body from below the mounting base. A mounting table position adjusting device for an electronic component mounting apparatus including a mounting table attaching / detaching mechanism, wherein one and the other of both end portions of a plurality of electronic component supply cassettes are arranged with respect to the mounting table mounted on the apparatus main body. Two auxiliary pressurizing units that pressurize from below, and rectangles at the four corners as viewed from the top of the mounting base mounted on the apparatus body, along the longitudinal direction and the alignment direction of the electronic component supply cassette The apex of Ranging means for detecting the distance in the height direction with respect to the four points, and as a result of detection by the ranging means, points that are less than the specified height are all four points or on the reel side in the longitudinal direction of the electronic component supply cassette. In the case of two points, both of the auxiliary pressurizing means are driven, and in the case of two points on one end side in the arrangement direction of the electronic component supply cassette, one corresponding auxiliary pressurizing means is driven. In the case of only one point, an operation control means for outputting an error signal is provided.
[0007]
In the above configuration, a plurality of electronic component supply cassettes are mounted on the mounting base, and are mounted on the electronic component mounting apparatus by the mounting base attaching / detaching mechanism. At the time of mounting, the mounting base is sandwiched by a mounting base receiving part located above the mounting base and a mounting base attaching / detaching mechanism that pressurizes the mounting base toward the base receiving part.
At this time, it is ideal if the mounting base is mounted in a state where it is in close contact with the base receiving portion. There may be a case where the applied pressure becomes insufficient and a gap is generated between the pedestal surface and the mounting table, or a foreign object enters between the pedestal surface and the mounting table to generate a gap.
[0008]
On the other hand, in the above configuration, distance measurement is performed by the distance measuring means at each of the four points that are the vertices of the rectangle along the longitudinal direction and the alignment direction of the electronic component supply cassette with respect to the mounting base after mounting. The reason why the four measurement points are set in this way is that it is premised that the factors causing the inclination of the mounting base are the excessive weight of each electronic component supply cassette and the intrusion of foreign matter.
In other words, the operation control means classifies the inclination state of the mounting table by the four-point distance measurement into a plurality of patterns, specifies which of the above-described inclination state patterns is the above factor, and processes according to each factor The process is performed so that
[0009]
That is, as the first pattern, when all four points or two points on the reel side in the longitudinal direction of the electronic component supply cassette are less than the specified height, the mounting base is almost entirely weighted electronic components. Assuming that the supply cassette is placed, the height position of the mounting base is optimized by driving both auxiliary pressurizing means.
As the second pattern, when two points located at one end in the arrangement direction of the electronic component supply cassette or two points located at the other end are less than the specified height, each electronic component supply of the mounting base is supplied. Assuming that overweight electronic component supply cassettes are centrally placed on one end or the other end in the direction of cassette alignment, even the auxiliary pressurizing means that pressurizes the concentrated end is driven. By doing so, the height position of the mounting base is optimized.
As the third pattern, if only one of the four points is less than the specified height, it is assumed that foreign matter is sandwiched in the area corresponding to one of the four points on the mounting base and the base. An error signal is output, and processing is performed so as to prompt an opportunity to remove foreign matter. The error signal may be output to the control means on the electronic component mounting apparatus side to stop the operation of the electronic component mounting apparatus or to output an error by a display means or a warning means provided in the electronic component supply cassette. . Further, the mounting position adjusting device itself may be provided with display means and warning means, and error output may be performed by these means.
[0010]
The specified height is the height of each of the four points when the mounting base is in contact with the pedestal in an appropriate state. When comparing the specified height with the detected height, A width may be provided for the value, and an allowable range may be set.
[0011]
The invention described in claim 2 has the same configuration as that of the invention described in claim 1, and the distance measuring means is provided in the electronic component holding head of the electronic component mounting apparatus that can move in the vertical and horizontal directions. Adopted.
In the above configuration, the same effect as that of the first aspect of the invention can be obtained, and when the four-point distance measurement is performed, the electronic component holding head is positioned for each point, and the distance measurement means is mounted on the mounting base from the head. Measure the distance.

[0022]
(Ranging means)
The distance measuring unit 11 includes a laser light source and a light receiving element that receives the reflected light. The laser light source emits laser light by a drive signal from the adjustment control unit 30. The light receiving element receives the reflected light of the laser light and outputs a light reception detection signal to the adjustment control means 30.
The distance measuring unit 11 is mounted on the component holding head 101 described above, and is conveyed above four measurement points in the feeder bank 112 to perform distance measurement.
The feeder bank 112 is provided with markings made of a material suitable for light reflection at the four corners of the mounting portion 114, and these serve as four measurement points. As for these four measurement points, position data when the feeder bank 112 is mounted on the mounting base attaching / detaching mechanism 120 is stored in advance in the adjustment control means 30, and the position control data and the drive command for the component holding head 101 are transmitted from the adjustment control means 30.

Note that the positioning means of the distance measuring means 11 may be provided independently for that purpose. Further, the distance measuring means 11 may be provided individually for each measurement point, and may be fixedly equipped in advance at the distance measuring position.
Further, in FIG. 1, for the sake of convenience, the distance measuring means 11 is also shown in the lower part of the figure, but actually only the one mounted on the component holding head 101.
[0023]
(Adjustment control means)
Although not shown in detail, the adjustment control means 30 is used as a CPU that performs various arithmetic processes, a ROM that stores and stores various programs for various processes such as control and determination described later, and a work memory for various processes. And a RAM. The control means 80 is connected to the switching valve 23 of each auxiliary pressurizing means 20 and 21, the laser light source of the distance measuring means 11, and the light receiving element via a system bus and a drive circuit.
[0024]
The adjustment control means 30 calculates the phase difference of the received light from the drive signal of the laser light source of the distance measuring means 11 and the detection signal from the vibration light receiving element, and further calculates the distance to each measurement point based on this. Furthermore, the adjustment control means 30 stores prescribed height data indicating a prescribed height threshold value for each measurement point, and compares the calculated detection height of each measurement point with the prescribed height. Then, a measurement point that does not satisfy the specified height is specified.
Furthermore, the adjustment control means 30 has a memory | storage part which memorize | stores the combination 1st-3rd pattern about the measurement point which is less than regulation height. As the first pattern, there are two types of cases where all measurement points Tfl, Tfr, Trl, Trr are targeted and two measurement points Tfr, Trr on the reel side in the longitudinal direction of the electronic component feeder are targeted. The second pattern targets two specific points Tfl and Trl on one end side in the X-axis direction, and the third pattern targets two specific points Tfr and Trr on the other end side in the X-axis direction. Applies only to any one of the measurement points Tfl, Tfr, Trl, Trr.
[0025]
And the adjustment control means 30 discriminate | determines which pattern is applicable when there exist one or more measurement points which are less than a regulation height.
In the case of the first pattern, the left and right auxiliary pressurized air is controlled by opening the two switching valves 23 because the electronic component feeder 111 mounted over the entire feeder bank 112 is overweight. The cylinder 22 is operated to push up the feeder bank 112 from both sides in the X-axis direction. Accordingly, both end portions of the feeder bank 112 are in close contact with the mounting base receiving portion 122 of the feeder bank support 121.
[0026]
In the case of corresponding to the second pattern, the switching valve 23 of the auxiliary pressurizing means 20 is regarded as being overweight by the electronic component feeder 111 mounted on one end side (left side in FIG. 1) of the feeder bank 112 in the X-axis direction. And the left auxiliary pressurized air cylinder 22 is operated to push up the feeder bank 112 toward one end side in the X-axis direction. Thereby, the lower end of the feeder bank 112 is brought into close contact with the mounting base receiving portion 122 of the feeder bank support 121.
[0027]
In the case of corresponding to the third pattern, the switching valve of the auxiliary pressurizing means 21 is assumed that the electronic component feeder 111 mounted on the other end side (right side in FIG. 1) in the X-axis direction of the feeder bank 112 is overloaded. 23 is controlled to open, and the right auxiliary pressurized air cylinder 22 is operated to push up the feeder bank 112 toward the other end side in the X-axis direction. Thereby, the other end part of the feeder bank 112 that has been lowered comes into close contact with the mounting base receiving part 122 of the feeder bank support 121.
[0028]
In the case of corresponding to the fourth pattern, it is assumed that a foreign object has entered between the feeder bank 112 and the mounting support 122 of the feeder bank support 121 in the vicinity of any one of the four measurement points of the feeder bank 112. The auxiliary pressurizing means 20 and 21 are not operated, and the adjustment control means 30 outputs an error signal to the main body control means of the electronic component mounting apparatus 100. In response to this, the main body control unit of the electronic component mounting apparatus 100 performs an error process such as a display indicating that a foreign object is caught, an error display, or stopping the operation of the electronic component mounting apparatus 100.
[0029]
(Description of operation of the mounting position adjustment device)
The operation of the electronic component mounting apparatus mounting position adjusting device 10 will be described with reference to FIG. First, the position data of each measurement point and the drive command for the component holding head from the adjustment control unit 30 are output to the main body control unit of the electronic component mounting apparatus 100. Thus, the component holding head 103 conveys the distance measuring means 11 to each measurement point, and distance measurement is performed for each measurement point (step S1).
[0030]
Further, the adjustment control means 30 calculates the distance of each measurement point based on the output from the light receiving element of the distance measurement means 11 and stores it (step S2). Then, the measurement distance of each measurement point is compared with a specified distance (height), and if there is a measurement point less than the specified height, this is stored (step S3). If there is no measurement point that does not reach the specified height, the process is terminated.
[0031]
If there is a measurement point that does not reach the specified height, it is compared whether it corresponds to the first pattern (step S4), and if so, the two auxiliary air cylinders 22 are activated to complete the process. (Step S5).
If it does not correspond to the first pattern, it is compared whether it corresponds to the second pattern (step S6), and if it corresponds, the auxiliary air cylinder 22 of the auxiliary pressurizing means 20 is actuated to end the processing ( Step S7).
If the pattern does not correspond to the second pattern, whether the pattern corresponds to the third pattern is compared (step S8). If the pattern corresponds, the auxiliary air cylinder 22 of the auxiliary pressurizing means 21 is operated to end the process. (Step S9).
[0032]
If the pattern does not correspond to the third pattern, whether the pattern corresponds to the fourth pattern is compared (step S10). If the pattern corresponds, the error signal is output and the process ends (step S11).
Further, when the pattern does not correspond to the fourth pattern (for example, when only the measurement points Tfl and Tfr are less than the prescribed height, or when only the measurement points Trl and Trr are less than the prescribed height), the processing is performed as it is. finish.
[0033]
(Effect of embodiment)
Since the electronic component mounting apparatus mounting position adjusting device 10 includes the two auxiliary pressurized air cylinders 22 that pressurize upward, the position adjustment of the feeder bank 112 in the vertical direction can be favorably performed.
Furthermore, since it is not necessary to cope with the vertical displacement of the feeder bank by correcting the target position of the component holding head of the electronic component mounting device in advance, the amount of vertical movement of the electronic component holding head can be reduced. Thus, it is possible to shorten the time for moving the head and reduce the burden on the driving means.
[0034]
(Other)
The auxiliary pressurizing means 20 and 21 pressurize upward by the auxiliary pressurizing cylinder. Instead, the feeder bank 112 is moved upward and downward by a motor drive capable of adjusting the rotation amount. It is good also as a structure which pressurizes so that quantity can be set freely. In that case, it is more desirable to adjust the vertical position with respect to the feeder bank 112 with respect to the distance corresponding to the difference between the height of the measurement point based on the distance measuring means 11 and the specified height.
[0035]
Moreover, in the said embodiment, although the mounting position adjustment apparatus 10 and the electronic component mounting apparatus 100 are set as another structure, it is good also as a structure by which the mounting position adjustment apparatus 10 is included as a part of the electronic component feeder 100. FIG. In that case, it is desirable that the main body control means execute all the functions of the adjustment control means 30.
[0036]
【The invention's effect】
According to the first aspect of the invention, since the auxiliary pressurizing unit that pressurizes the mounting base upward is provided, unlike the conventional case, it is possible to optimize the position of the mounting base in the vertical direction. .
Further, since the height of the mounting base is optimized by pressurizing the mounting base after mounting, the amount of vertical movement of the component holding head of the electronic component mounting apparatus can be reduced as in the past. Therefore, it is possible to shorten the time for moving the head, to improve the work efficiency, and to reduce the burden on the driving means.
[0037]
According to the second aspect of the present invention, since the distance measuring means is mounted on the electronic component holding head, it is possible to perform distance measurement on all the measurement points by one distance measuring means, and an apparatus by reducing the number of parts. It becomes possible to improve the productivity. Further, four measurement points can be freely set within the movable range of the component holding head.
