Description

The present invention relates to an automatic switching device and an automatic switching system that automatically sets and removes feeders from the feeder setting portions of a plurality of component mounting machines arranged along the transport direction of a circuit board.

As described in Patent Document 1 (International Publication WO2014 / 010083), this type of component mounting line is a moving lane provided along an arrangement of a plurality of component mounting machines constituting the component mounting line. An automatic switching device (loader) is movably installed in the vehicle, and this automatic switching device is moved to the front of the component mounting machine specified in the production job (production program), etc., to the feeder set section of the component mounting machine. I try to set and remove the feeder.

A motor that drives the rotation is provided, and the pinion is driven to rotate with this motor, so that the automatic switching device can be moved along the moving lane and the rotation angle of the motor (rotation angle of the pinion) can be detected by an encoder or the like. , The movement distance of the automatic exchange device is measured based on the detected value, the position of the automatic exchange device is detected, and the movement of the automatic exchange device is controlled.

International Publication WO2014 / 010083 Gazette

In Patent Document 1, the automatic exchange device is moved by the meshing of teeth between the rack and the pinion, but the meshing of the teeth between the rack and the pinion due to manufacturing variation, assembly variation, tooth wear, etc. of those components. There are drawbacks such as poor condition, teeth interfering with each other, hindering smooth rotation, loud noise, and tooth damage.

As a solution to this drawback, the present inventor considers adopting a configuration in which the automatic switching device is moved by a drive wheel that is rotationally driven by a motor instead of the rack and the pinion. Since it may slip, even if the rotation angle of the motor or the rotation angle of the drive wheel is accurately detected, an error due to the slip of the drive wheel occurs between the detected value and the moving distance of the automatic switching device. The position of the automatic switching device cannot be detected accurately.

As a countermeasure, it is conceivable to provide a distance sensor or a linear scale for measuring the moving distance (position) of the automatic switching device, but there are the following problems.

Currently, commercially available wire-type distance sensors have low durability, and measurement accuracy cannot be stably ensured. Further, the laser distance sensor is expensive, the measurement operation is easily affected by the atmospheric condition and is unstable, and there is a concern about the risk of blocking the laser beam and the influence on the eyes of the operator. In addition, the linear scale has a large sensor head and is expensive, and it is necessary to replace the scale or add more scales every time the number of component mounting machines installed (line length) is increased or decreased, which is troublesome. At the same time, the seam of the scale is a factor that lowers the measurement accuracy.

Therefore, the problem to be solved by the present invention is to enable stable and accurate detection of the position of the automatic switching device with an inexpensive configuration and to cope with an increase or decrease in the number of component mounting machines installed by a simple operation. That is.

In order to solve the above problems, the automatic switching apparatus of the present invention sets a feeder in a feeder set portion of each component mounting machine of a component mounting line in which a plurality of component mounting machines are arranged along a transport direction of a circuit board. And a reference position when the position of the position detection device for detecting the position of the automatic replacement device and the position of the automatic replacement device coincide with the reference position set in each component mounting machine. It is characterized by including a reference position detecting unit that outputs a detection signal, and a control device that moves the automatic switching device to a designated position based on the detection position of the position detecting device to set and remove the feeder. And.

Alternatively, the automatic switching device of the present invention is a component mounting machine when the position of the position detecting device for detecting the position of the automatic switching device and the position of the automatic switching device match the reference position set for each component mounting machine. The configuration also includes a reference unit detected by the reference position detection unit and a control device that moves the automatic switching device to a designated position based on the detection position of the position detection device to set and remove the feeder. good.

Further, the automatic exchange system of the present invention is an automatic exchange system including an automatic exchange device for setting and removing a feeder to a feeder set portion of each component mounting machine of a component mounting line, and the position of the automatic exchange device is determined. A reference position that outputs a reference position detection signal when the position of the position detection device to be detected, the component mounting machine in which the reference position is set, and the position of the automatic replacement device match the reference position of the component mounting machine. It is characterized by including a detection unit and a control device for moving the automatic switching device to an instructed position based on the detection position of the position detection device to set and remove the feeder.

Alternatively, in the automatic exchange system of the present invention, a position detection device for detecting the position of the automatic exchange device, each component mounting machine in which a reference position is set, and the position of the automatic exchange device are the above-mentioned of each component mounting machine. When the reference position is matched, the reference unit detected by the reference position detection unit of the component mounting machine and the automatic replacement device based on the detection position of the position detection device are moved to the designated positions of the feeder. The configuration may include a control device for setting and removal.

In addition, although not shown, the cassette case 32 is provided with a connector for communication / power supply connected to the connector for communication / power supply on the component mounting machine 12 side.

As shown in FIG. 1, on the front side of the component mounting line 10, an automatic switching device 26 for setting and removing the cassette type feeder 14 on the feeder setting unit 24 of each component mounting machine 12 is installed. Below the feeder set unit 24 of each component mounting machine 12, a stock unit 71 for accommodating a plurality of feeders 14 to be set in the feeder set unit 24 is provided. The automatic switching device 26 takes out the feeder 14 to be replaced from the feeder set unit 24 of the plurality of component mounting machines 12, collects it in the stock unit 71, and collects the feeder 14 specified in the production job (production program) from the stock unit 71. Is taken out and set in the feeder setting unit 24 of the plurality of component mounting machines 12.

On the front side of the component mounting line 10, a guide rail 74 for moving the automatic switching device 26 in the left-right direction (X direction) along the arrangement of the component mounting machines 12 is provided so as to extend in the X direction over the entire component mounting line 10. Has been done. The board carry-in side of the guide rail 74 is extended to the feeder storage device 19, the automatic switching device 26 is moved to the front side of the feeder storage device 19, and the automatic switching device 26 is designated from the feeder storage device 19 in the production job. The feeder 14 is taken out, and the used feeder 14 is returned to the feeder storage device 19.

As shown in FIG. 5, on the back side of the automatic switching device 26, a plurality of guide rollers 54 for regulating the Y direction, which regulate the movement of the automatic switching device 26 in the Y direction (direction orthogonal to the X direction), and automatic A plurality of guide rollers 55 for Z-direction regulation that regulate the movement of the switching device 26 in the Z-direction (vertical direction) are rotatably provided alternately, and the guide rollers 54 for Y-direction regulation are provided on the side wall of the guide rail 74. The guide roller 55 for Z-direction regulation rolls along the plane of the guide rail 74, so that the moving direction of the automatic switching device 26 is guided only in the X direction.

The space on the front side of the component mounting line 10 is a moving lane in which the automatic switching device 26 moves in the X direction, and the moving rail 75 extends in the X direction on the guide rail 74 on the front side of the component mounting line 10. It is provided as follows. On the other hand, the automatic switching device 26 is provided with a drive device 78 for rotationally driving a drive wheel 76 made of an elastic material such as rubber by a motor (not shown) via a belt transmission mechanism 77. By rolling the wheel 76 along the moving rail 75, the automatic switching device 26 is driven in the X direction.

Next, the configuration of the position detecting device 81 for detecting the position of the automatic switching device 26 will be described with reference to FIGS. 5 and 6.

An endd timing belt 82 made of an elastic material such as rubber is provided so as to extend linearly in the X direction along the guide rail 74. The length of the timing belt 82 is longer than the length of the number of installed component mounting machines 12 (the length of the component mounting line 10), preferably at least one longer than the length of the number of installed component mounting machines 12. It is formed long. In this case, it is not necessary to cut the extra part of the timing belt 82 according to the number of component mounting machines 12 installed, and the extra part of the timing belt 82 is attached to the back surface of the guide rail 74 or the like, bundled, or the like. The extra part of the timing belt 82 may not be in the way.

On the other hand, the automatic switching device 26 is provided with a timing pulley 83 that moves together with the automatic switching device 26 while maintaining the state of meshing with the teeth of the timing belt 82. The support mechanism 84 that supports the timing pulley 83 has a direction in which the timing pulley 83 is orthogonal to the timing belt 82 within a range in which the teeth of the timing pulley 83 and the teeth of the timing belt 82 do not disengage (vertical direction in this embodiment). A urging means 85 (for example, a spring such as a spring, an elastic member such as rubber) is provided to urge the timing pulley 83 in a direction of pressing the timing pulley 83 against the timing belt 82.

Further, the automatic switching device 26 is provided with a magnetic or optical rotary encoder 87 as a rotation angle sensor for detecting the rotation angle of the timing pulley 83. The rotary encoder 87 is a rotary encoder capable of detecting forward / reverse rotation that outputs a pulse each time the timing pulley 83 rotates by a predetermined angle, and the output pulse of the rotary encoder 87 is the control device 90 of the automatic switching device 26 (FIG. 3). See).

The control device 90 of the automatic switching device 26 also functions as a detection circuit unit that detects the position of the automatic switching device 26 based on the output pulse of the rotary encoder 87 (hereinafter referred to as “encoder pulse”), and the automatic switching device 26 During movement (during rotation of the timing pulley 83), the encoder pulse is counted, and the up / down of the counting operation is switched according to the rotation direction of the timing pulley 83 (movement direction of the automatic switching device 26). The position of the automatic switching device 26 is detected based on the count value of the encoder pulse while maintaining the correspondence between the count value of the above and the position of the automatic switching device 26. At this time, the encoder pulse counting operation may be performed by an up / down counter configured by an electronic circuit (hardware), or the function of the up / down counter may be realized by software installed in the control device 90.

In this embodiment, the support mechanism 84 that supports the timing pulley 83 makes the timing pulley 83 orthogonal to the timing belt 82 (Z direction) within a range in which the teeth of the timing pulley 83 and the teeth of the timing belt 82 do not disengage. ), And the urging means 85 for urging the timing pulley 83 in the direction of pressing the timing belt 82 against the timing belt 82 is provided. Even if there is a slight step between the component mounting machines 12 due to the deviation and a slight step is formed on the timing belt 82, the timing pulley 83 is made to follow the step and displaced to stabilize the meshing with the timing belt 82. The position detection accuracy of the automatic switching device 26 can be stably maintained even with respect to a step between the component mounting machines 12.

By the way, when the position detecting device 81 detects the position of the automatic switching device 26, it is necessary to set a reference position at at least one place, and the moving distance of the automatic switching device 26 from the reference position is counted as the count value of the encoder pulse. It is measured from the rotation amount (rotation angle) of the timing pulley 83 detected in step 1, and the position of the automatic exchange device 26 is detected from the measured value with reference to the reference position to control the movement of the automatic exchange device 26. .. In this case, if each of the plurality of component mounting machines 12 constituting the component mounting line 10 is installed accurately without misalignment, even if there is only one reference position, the moving distance of the automatic switching device 26 from the reference position. There is no discrepancy in the correspondence between (position) and the positions of the plurality of component mounting machines 12, but in reality, each of the plurality of component mounting machines 12 is installed with a slight misalignment. Since there is a possibility, there is a possibility that the correspondence relationship between the moving distance (position) of the automatic switching device 12 from the reference position and each position of the plurality of component mounting machines 12 is different. If this correspondence relationship is deviated, the position of the automatic switching device 26 cannot be accurately controlled for each of the plurality of component mounting machines 12, and a setting error or a removal error of the feeder 14 for each component mounting machine 12 occurs. there's a possibility that.

As a countermeasure, in this embodiment, a reference position is set for each of two or more (all in this embodiment) component mounting machines 12 among the plurality of component mounting machines 12 constituting the component mounting line 10. At the same time, a reference position detection sensor 91 (reference position detecting means) that outputs a reference position detection signal when the position of the automatic exchange device 26 matches the reference position of the component mounting machine 12 is provided to control the automatic exchange device 26. The device 90 corrects the detection position (encoder pulse count value) of the position detection device 81 so as to correspond to the reference position of the component mounting machine 12 when the reference position detection signal is output from the reference position detection sensor 91. .. By doing so, the moving distance (position) of the automatic switching device 26 can be detected with reference to the reference position of two or more component mounting machines 12 among the plurality of component mounting machines 12, so that the moving distance (position) from the reference position can be detected. It is possible to reduce or eliminate the deviation of the correspondence between the moving distance (position) of the automatic switching device 26 and each position of the plurality of component mounting machines 26, and automatically for each of the plurality of component mounting machines 12. The position of the switching device 26 can be controlled with high accuracy, and it is possible to prevent mistakes in setting or removing the feeder for each component mounting machine 12.

In this case, when the automatic switching device 26 is moved by the drive device 78 during the installation of the component mounting machine 12 or the calibration operation before the start of production, and the position of the automatic switching device 26 matches the reference position of the component mounting machine 12. Correspondence between the detection position (count value of encoder pulse) of the automatic switching device 26 and the reference position of the component mounting machine 12 is determined by the non-volatile storage means 92 (for example, hard disk, ROM, EEPROM, etc.) of the control device 90 of the automatic switching device 26. The control device 90 of the automatic switching device 26 stores the detection position (encoder pulse count value) of the position detection device 81 based on the storage data of the storage means 92 during production. Interference correction is performed by linear interpolation or the like between the 12 reference positions. By doing so, the accuracy of detecting the position of the automatic switching device 26 between the reference positions of the component mounting machine 12 can be improved.

By the way, in the reference position detection process (initial process) at the start of production, the automatic replacement device 26 is moved to the reference position of the component mounting machine 12, and the detection position (encoder pulse count value) of the position detection device 81 is set to the component mounting machine. It is necessary to correct it so that it corresponds to the reference position of 12, but if the stop position of the automatic switching device 26 before the start of production is far from the reference position of the component mounting machine 12, the reference position detection process at the start of production It takes time, and the start of production will be delayed by that amount.

Therefore, in this embodiment, the control device 90 of the automatic switching device 26 moves the automatic switching device 26 to the reference position of the nearest component mounting machine 12 by the drive device 78 in the reference position detection process at the start of production to detect the position. The detection position (count value of the encoder pulse) of the device 81 is corrected so as to correspond to the reference position of the component mounting machine. By doing so, the distance until the automatic replacement device 26 is moved to the reference position of the component mounting machine 12 in the reference position detection process at the start of production can be shortened, and the reference position detection process at the start of production can be shortened. You can save time.

Here, as the reference position detection sensor 91, for example, a non-contact type sensor such as an optical sensor or a proximity sensor may be used, or a contact type switch such as a limit switch may be used. Further, the reference position detection sensor 91 may be provided in the automatic switching device 26 or in the component mounting machine 12.

For example, when the reference position detection sensor 91 is provided in the automatic switching device 26, it is automatically replaced in each of two or more (all in this embodiment) component mounting machines 12 out of the plurality of component mounting machines 26. A reference unit (not shown) that is detected by the reference position detection sensor 91 of the automatic switching device 26 when the position of the device 26 matches the reference position of the component mounting machine 12 may be provided.

On the other hand, when the reference position detection sensor 91 is provided in each of two or more component mounting machines 12 out of the plurality of component mounting machines 12, the position of the automatic switching device 26 is mounted on the automatic switching device 26. A reference unit (not shown) that is detected by the reference position detection sensor 91 of the component mounting machine 12 when it matches the reference position of the machine 12 may be provided.

As shown in FIG. 3, the control device 90 of the automatic switching device 26 is connected to the production control computer 70 of the component mounting line 10 via a network, and information on the production job transmitted from the production control computer 70 of the component mounting line 10. According to this, while the position detecting device 81 detects the position of the automatic switching device 26, the driving device 78 moves the automatic switching device 26 to the position of the component mounting machine 12 specified in the production job, and the component mounting machine 12 is moved. It controls the operation of setting and removing the feeder 14 in the feeder setting unit 24.

In the present embodiment described above, a configuration in which the automatic switching device 26 is moved by the drive wheels 76 is adopted, and a plurality of component mounting machines 12 are used while realizing smooth movement, low noise, improved durability, and the like. By detecting the rotation angle of the timing pulley 83 that meshes with the timing belt 82 provided straddling the rotary encoder 87, the rotation angle of the drive wheel 76 caused by the slip of the drive wheel 76 and the moving distance of the automatic switching device 26 are set. The error between them can be canceled and the position of the automatic switching device 26 can be detected with high accuracy. Moreover, since the timing belt 82, the timing pulley 83, and the rotary encoder 87 constituting the position detection device 81 can use mass-produced products that are commercially available at low cost, the position detection device 81 can be inexpensively and compactly configured and has durability. Further, since it is only necessary to attach one timing belt 82 across a plurality of component mounting machines 12 when installing the component mounting machine 12, the amount of work of the operator can be reduced. In addition, the length of the timing belt may be longer than the number of installed component mounting machines, and it is not necessary to cut an extra part of the timing belt 82 according to the number of installed component mounting machines 12. It is possible to attach the extra part of the timing belt 82 to a place that does not get in the way, bundle it, and so on, and it is possible to increase or decrease the number of component mounting machines 12 installed (line length) with a simple operation.

In the above embodiment, the rotary encoder 87 is used as the rotation angle sensor for detecting the rotation angle of the timing pulley 83, but another rotation angle sensor such as a resolver may be used.
In addition, the present invention is not limited to the above embodiment, and the configuration of the component mounting machine 12 and the configuration of the automatic switching device 26 may be appropriately changed, the configuration of the feeder 14 may be appropriately changed, and the like does not deviate from the gist. Needless to say, it can be changed and implemented within the range.
