Description

[Technical Field]

[0001] The technology disclosed in this specification relates to a component supply feeder, and a component supply feeder management system and management method. [Background technology]

[0002] For example, an autoloading feeder (ALF) is being considered as a component supply feeder attached to a mounter. This feeder is configured to supply one carrier tape while another carrier tape is being supplied, keeping the other carrier tape in a supply standby state. In this case, the other carrier tape is automatically supplied, and the state of the carrier tape is monitored by multiple detection sensors.

[0003] However, when an error occurs in a component supply feeder, it may be difficult to determine the cause of the error just by looking at it, making it difficult to deal with the problem. Patent Document 1 discloses a technique for saving a trace log of a component supply feeder in a trace memory within the component supply feeder when an error occurs. With this technique, the cause of the error can be investigated by reading the trace log from the trace memory after the error occurs. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2017 / 072889 Summary of the Invention [Problem to be solved by the invention]

[0005] However, because the trace log does not include information indicating the state transition of the sensor that detects the carrier tape, there is a problem that it is not possible to confirm the occurrence of an error and to accurately identify the cause of the error. Therefore, this specification provides a technology that makes it possible to confirm the occurrence of an error and to easily identify the cause. [Means for solving the problem]

Therefore, with the above-described configuration, the occurrence status of an error can be confirmed using the state transition information for the multiple detection sensors, making it easier to identify the cause.

[0007] The component supply feeder management system disclosed in this specification includes a component supply feeder, a memory, and an external device. The component supply feeder has multiple detection sensors and a control unit. The multiple detection sensors detect the carrier tape containing electronic components or the electronic components. The control unit controls the supply operation of the carrier tape based on the detection results of the multiple detection sensors. The memory stores state transition information of the multiple detection sensors. The external device is configured separately from the component supply feeder and the memory. The external device generates a trace file used to identify the cause of an error based on the state transition information of the multiple detection sensors read from the memory.

[0010] The component supply feeder disclosed in this specification may be an autoloading feeder configured to replenish one carrier tape while supplying another carrier tape and keep the other carrier tape in a standby state for supply.

[0011] In the component supply feeder disclosed in this specification, the plurality of detection sensors may include a step sensor that detects a step that occurs when two carrier tapes are overlapped. With this configuration, the overlapping state of the two carrier tapes can be monitored.

[0012] In the component supply feeder disclosed in this specification, the multiple detection sensors may include a step sensor that detects a step caused by the overlapping of the two carrier tapes, at least one upstream tape detection sensor arranged upstream in the tape feed direction from the step sensor, and at least one downstream tape detection sensor arranged downstream in the tape feed direction from the step sensor. This configuration makes it possible to monitor the overlapping state of the two carrier tapes and the states of the carrier tapes before and after that.

[0013] The component supply feeder disclosed in this specification may further include an operation unit having a plurality of buttons. When the plurality of buttons are operated in a manner different from normal operations that instruct the operation of the carrier tape, the control unit may read state transition information of the plurality of detection sensors from the memory and output the information to an external device. With this configuration, the state transition information can be output to the external device using the plurality of buttons that instruct the operation of the carrier tape.

[0014] In the component supply feeder disclosed in this specification, the control unit may be capable of outputting state transition information of the multiple detection sensors to a feeder inspection jig for inspecting and adjusting the component supply feeder.

[0015] The component supply feeder management method disclosed in this specification may further include the steps of reading from the memory the state transition information of the plurality of detection sensors stored in the memory and outputting the information to an external device, and generating a trace file used to identify the cause of an error based on the state transition information of the plurality of detection sensors output to the external device. With this configuration, it is possible to more easily identify the cause of an error.

[0016] (Example) Hereinafter, a management system 1 for component supply feeders 30 according to this embodiment will be described with reference to the drawings. As shown in Fig. 1, the management system 1 is a system for managing component supply feeders 30 installed in component mounters 10. In addition, in the management system 1, a plurality of component mounters 10 are arranged along the transport direction of boards 2 (see Figs. 2 and 3).

[0017] As shown in FIGS. 2 and 3, the component mounter 10 is a device for mounting electronic components 3 on a board 2. The component mounter 10 has a feeder attachment / detachment unit 11 that detachably holds multiple component supply feeders 30. Each component supply feeder 30 is for supplying electronic components 3 for board mounting. In this embodiment, the component supply feeders 30 are tape-type feeders that store multiple electronic components 3 on carrier tapes t1 and t2 (see FIG. 4). The component mounter 10 takes out electronic components 3 from each component supply feeder 30 attached to the feeder attachment / detachment unit 11 and mounts them on the board 2.

[0018] The component mounter 10 also includes a board transport device 12, a component mounting head 13, a head moving device 14, a control device 21, and a touch panel 22. The board transport device 12 is a device that performs the following operations: transporting the board 2 to a work position (not shown) within the component mounter 10; positioning the board 2 at the work position before component mounting; and transporting the board 2 from the work position after component mounting. The board transport device 12 of this embodiment can be configured, for example, with a pair of belt conveyors 15, a support device (not shown) attached to the belt conveyors 15 and supporting the board 2 from below, and a drive device (not shown) that drives the belt conveyor 15. The board 2 is transported from upstream (left side in FIG. 1) to downstream (right side in FIG. 1) of the management system 1.

[0019] The component mounting head 13 is equipped with one or more suction nozzles 16. The suction nozzles 16 are configured to be able to be raised and lowered in the vertical direction (Z direction) by an actuator (not shown) housed in the component mounting head 13 and to be able to pick up and hold electronic components 3.

[0020] To mount the electronic component 3 on the board 2 using the component mounting head 13, first, the suction nozzle 16 is moved downward until the suction surface of the suction nozzle 16 abuts against the electronic component 3 stored in the component supply feeder 30. Next, the suction nozzle 16 picks up the electronic component 3, and then the suction nozzle 16 is moved upward. Once the process of picking up the electronic component 3 onto the suction nozzle 16 is complete, the head moving device 14 is driven to position the component mounting head 13 with respect to the board 2. Then, the suction nozzle 16 is lowered toward the board 2, thereby mounting the electronic component 3 on the board 2.

[0021] The control device 21 is a computer configured with a CPU, memory, etc. The control device 21 controls the operation of each part of the component mounter 10 based on a production program transmitted from the control device 4 (see FIG. 1). The touch panel 22 is a display device that displays various information about the component mounter 10, and is also a user interface that receives instructions and information from the operator.

[0022] As shown in Fig. 4, the component supply feeder 30 of this embodiment is a feeder that supplies electronic components 3 by feeding (supplying) one carrier tape t1 along the transport path R1. The component supply feeder 30 is an autoloading feeder (ALF) that is configured to replenish another carrier tape t2 while supplying one carrier tape t1 and to maintain a supply standby state for the other carrier tape t2. When the remaining amount of one carrier tape t1 falls below a specified value, the component supply feeder 30 discharges the one carrier tape t1, and then feeds and loads the other unspliced ​​carrier tape t2 onto the transport path R1.

[0023] The carrier tapes t1 and t2 are wound around reels (not shown) held by a reel holding unit (not shown) provided in the component supply feeder 30. The carrier tapes t1 and t2 house a plurality of electronic components 3. The carrier tapes t1 and t2 are each made up of a base tape (not shown) and a cover tape (not shown).

[0024] The base tape is made of a flexible material such as paper or resin, and has a plurality of storage recesses. The storage recesses are arranged at regular intervals along the length of the base tape. Each storage recess stores one electronic component 3.

[0025] The cover tape is made of a thin polymer film. Both widthwise edges of the cover tape are adhered to the upper surface of the base tape. This allows the cover tape to close the openings of the storage recesses in the base tape, preventing the electronic components 3 from falling out of the storage recesses.

[0026] 4, the component supply feeder 30 includes a feeder body 31, a first drive device 32, a second drive device 33, and a control unit 41. In this embodiment, the downstream side in the tape transport direction in which the carrier tape t1 is fed (the "downstream side in the transport direction" in FIG. 4) is defined as the front, and the upstream side in the tape transport direction (the "upstream side in the transport direction" in FIG. 4) is defined as the rear.

[0027] The feeder main body 31 is formed in a flat box shape and can be attached to a slot of the feeder attaching / detaching unit 11 provided in the component mounter 10. An insertion unit A1 into which the carrier tapes t1 and t2 are inserted is provided at the rear of the feeder main body 31, and an ejection unit A2 from which the carrier tapes t1 and t2 are ejected is provided at the front of the feeder main body 31. A transport path R1 is provided within the feeder main body 31 to support the carrier tapes t1 and t2 inserted from the insertion unit A1. The transport path R1 is composed of rails 34 provided within the feeder main body 31. The transport path R1 is used to feed electronic components 3 housed in the carrier tapes t1 and t2.

[0028] The first drive unit 32 has a pair of sprockets 32a, 332b provided below the rails 34 near the insertion unit A1. The second drive unit 33 has a pair of sprockets 33a, 33b provided below the rails 34 near the discharge unit A2. The sprockets 32a, 32b, 33a, 33b are capable of engaging with the carrier tapes t1, t2 on the transport path R1. The first drive unit 32 rotates the sprockets 32a, 32b using a rear-side motor 48 (see FIG. 6), and the second drive unit 33 rotates the sprockets 33a, 33b using a front-side motor 49 (see FIG. 6).

[0029] As shown in Fig. 4, the component supply feeder 30 is equipped with multiple detection sensors that detect carrier tapes t1 and t2. Specifically, each detection sensor includes a step sensor 52 that detects a step D1 that occurs when the two carrier tapes t1 and t2 are overlapped. Each detection sensor also includes an entrance sensor 51 that detects carrier tapes t1 and t2 that have entered the feeder main body 31 from the insertion section A1. The entrance sensor 51 is an example of a single upstream tape detection sensor that is located upstream in the tape feed direction ("rear" in Fig. 4) relative to the step sensor 52. The entrance sensor 51 is also located near the insertion section A1 within the feeder main body 31.

[0030] Furthermore, each detection sensor includes a tape end sensor 53 and a suction portion sensor 54. The tape end sensor 53 detects the rear end (tape end) of the carrier tape t1 when the two overlapping carrier tapes t1, t2 become one carrier tape t2. The suction portion sensor 54 detects the rear end of the carrier tape t1 when the carrier tape t1 is discharged from the discharge section A2. The tape end sensor 53 and the suction portion sensor 54 are examples of downstream tape detection sensors located downstream in the tape feed direction ("forward" in FIG. 4) relative to the step sensor 52. Specifically, the tape end sensor 53 is located slightly forward of the sprocket 32b of the first drive device 32, and the suction portion sensor 54 is located slightly rearward of the sprocket 33a of the second drive device 33.

[0031] As shown in FIG. 4, the component supply feeder 30 further includes an operation unit 46 having three buttons 46a, 46b, and 46c. Button 46a is an AUTO button that is operated to instruct the operation of the carrier tapes t1 and t2. Button 46b is a feeder trace acquisition button that is operated to instruct the creation of a trace file used to identify the cause of an error. Furthermore, the component supply feeder 30 includes a display unit 47 near the operation unit 46. Display unit 47 is configured using LEDs.

[0032] The control unit 41 of the component supply feeder 30 is capable of outputting state transition information of each of the sensors 51-54 to a feeder inspection jig 91 (see FIG. 5) that is used to inspect and adjust the component supply feeder 30. The state transition information of the detection sensors refers to information that indicates the transition of the state (e.g., on, off) of the signals output from the sensors 51-54.

[0033] As shown in Figure 5, feeder inspection jig 91 includes a support base 92, a communication socket 93, an imaging camera 94, and a jig control unit 95. A slot (not shown) is formed on the side of support base 92. When component supply feeder 30 is inserted into the slot of support base 92, a communication connector (not shown) of component supply feeder 30 is inserted into and connected to communication socket 93. In addition, communication socket 93 is electrically connected to jig control unit 95. This connects jig control unit 95 to control unit 41 of component supply feeder 30, enabling necessary information to be exchanged between jig control unit 95 and control unit 41.

[0034] The imaging camera 94 is disposed directly above the component supply feeder 30 inserted into the slot of the support base 92. The imaging camera 94 performs imaging operations in response to instructions from the jig control unit 95, and outputs the acquired image data to the jig control unit 95. The imaging camera 94 has a resolution that allows it to capture an image of a measurement marker (not shown) on a measurement tape 97 wound around a reel 96.

[0035] Here, we will explain a method for inspecting the positional accuracy of component supply feeder 30 using feeder inspection jig 91. During inspection, component supply feeder 30 is loaded with measuring tape 97 instead of carrier tapes t1 and t2.

[0036] First, the jig control unit 95 acquires a feeder identification code from the control unit 41 of the component supply feeder 30 inserted into the slot of the support base 92. Next, the jig control unit 95 controls the rotation of the reel 96, causing the measuring tape 97 to be fed to a feed position (not shown) within the component supply feeder 30. Furthermore, the jig control unit 95 controls the component supply feeder 30 to alternately feed the measuring tape 97 intermittently and the imaging camera 94 to capture images of the measurement markers.

[0037] The jig control unit 95 then measures the accuracy of the feed amount of the measuring tape 97, i.e., the positional accuracy at the feed position, based on the image data of the multiple measurement markers acquired consecutively. The positional accuracy is highest when all of the measurement markers on each image data are in the same position. Thereafter, the jig control unit 95 transmits positional accuracy data, which associates the feeder identification code with the obtained positional accuracy, to the control device 4 (see FIG. 1).

[0038] The feeder inspection jig 91 sequentially measures the positional accuracy at the supply position for each of the component supply feeders 30 being measured. It is also preferable to measure the positional accuracy again for the same component supply feeder 30 after a long period of operation or when significant stress has been applied. Here, the positional accuracy at the supply position can also be referred to as the accuracy of the stopping position of the storage recess of the carrier tape t1 relative to the supply position. If the deviation between the stopping position of the storage recess and the supply position becomes too great, the electronic components 3 in the storage recess cannot be picked up.

[0039] 6, the component supply feeder 30 constituting the management system 1 includes a control unit 41 that controls the operation of the component supply feeder 30. When the component supply feeder 30 is set in the component mounter 10, the control unit 41 starts supplying power from the component mounter 10 via a connector (not shown), and the control unit 41 becomes capable of communicating with the component mounter 10.

[0040] The control unit 41 is made up of a computer including a CPU 42, a memory 43, etc. An entrance sensor 51, a step sensor 52, a tape end sensor 53, and a suction portion sensor 54 are connected to the CPU 42. A rear motor 48 of the first drive device 32 and a front motor 49 of the second drive device 33 are also connected to the CPU 42. An operation unit 46 and a display unit 47 are also connected to the CPU 42.

[0041] The CPU 42 then controls the supply operation of the carrier tape t1, specifically the operation of the first drive device 32 and the second drive device 33, based on the detection results of the sensors 51 to 54. For example, the CPU 42 controls the rotation of the rear-side motor 48 and the front-side motor 49 that feed the carrier tape t1 to a component suction position (not shown) in the component supply feeder 30. The memory 43 also stores state transition information of the sensors 51 to 54.

[0042] CPU 42 is capable of reading out the state transition information of each of sensors 51-54 from memory 43 and outputting it to component mounter 10, which is an external device of component supply feeder 30, and feeder inspection jig 91, which is also an external device. Feeder inspection jig 91 is configured separately from component supply feeder 30 and memory 43, as described above, and generates a trace file used to identify the cause of an error based on the state transition information of each of sensors 51-54 read out from memory 43.

[0043] Next, a method for managing the component supply feeder 30 will be described.

[0044] First, in a first step, the CPU 42 of the component supply feeder 30 stores state transition information for each of the sensors 51-54 in the memory 43. The monitoring intervals of the sensors 52-54 may be long or short. For example, in this embodiment, the level difference sensor 52 frequently monitors whether or not there is a level difference D1. Meanwhile, the other sensors 51, 53, and 54 monitor the carrier tapes t1 and t2 less frequently than the level difference sensor 52. When the storage area of ​​the memory 43 becomes full, new state transition information is overwritten on the state transition information already stored in the memory 43. The memory 43 in this embodiment is a non-volatile memory, such as a flash memory, whose information is not erased even when the power to the component supply feeder 30 is turned on and off.

[0045] If an error of unknown cause occurs in the component supply feeder 30, the CPU 42 controls the yellow display unit 47 (LED) to blink. Next, the CPU 42 performs a second step. Specifically, the CPU 42 reads out the state transition information of each sensor 51-54 stored in the memory 43 from the memory 43 when a button is operated in a manner different from the normal operation for instructing the operation of the carrier tapes t1 and t2. Note that in this embodiment, an operation in a manner different from the normal operation refers to, for example, simultaneously pressing the button 46a (AUTO button) and the button 46b (feeder trace acquisition button). Also, the normal operation for instructing the operation of the carrier tapes t1 and t2 refers to pressing only one button 46a for a short period of time.

[0046] Next, after pressing buttons 46a and 46b, the worker removes component supply feeder 30 in which the error occurred from feeder attachment / detachment unit 11 of component mounter 10. Furthermore, when the worker inserts removed component supply feeder 30 into a slot of support base 92 (feeder inspection jig 91) (see FIG. 1), the communication connector (not shown) of component supply feeder 30 is inserted into and connected to communication socket 93. Then, when the communication connector is connected to communication socket 93, CPU 42 outputs the state transition information of each sensor 51-54 stored in memory 43 to jig control unit 95 of feeder inspection jig 91.

[0047] In the following third step, the jig control unit 95 of the feeder inspection jig 91 generates a trace file to be used for identifying the cause of the error based on the output state transition information of each of the sensors 51 to 54. The generated trace file is then analyzed to identify the cause of the error. The identified cause is notified to the worker, so that the worker can take action based on the notified cause.

[0048] As described above, the component supply feeder 30 management system 1 of this embodiment stores the state transition information of each sensor 51-54 in memory 43 during normal operation, and when an abnormality occurs, reads the state transition information of each sensor 51-54 from memory 43 and outputs it to the feeder inspection jig 91. The feeder inspection jig 91 then generates a trace file based on the read state transition information. This makes it possible to check the occurrence status of the error from the trace file, making it easier to identify the cause.

[0049] In the management system 1 of this embodiment, the feeder inspection jig 91 generates a trace file based on the state transition information of each sensor 51-54. Therefore, even if an error is not currently occurring, the circumstances and cause of the error can be investigated based on the trace file. Furthermore, once the trace file is generated, the error can be investigated, allowing the component supply feeder 30 to be used.

[0050] In the management system 1 of this embodiment, the operator can generate a trace file only when necessary by pressing specific buttons 46a and 46b at his / her discretion. Furthermore, since the operator needs to press two buttons 46a and 46b simultaneously to output state transition information, unintended output of state transition information can be prevented.

[0051] In the component supply feeder 30 of this embodiment, by operating buttons 46a and 46b, state transition information is output (moved) to the feeder inspection jig 91 to generate a trace file. In other words, because the operation of buttons 46a and 46b is performed at the operator's discretion, a trace file can be generated by operating buttons 46a and 46b even if no error has occurred.

[0052] Although the above describes the embodiments, the specific aspects are not limited to the above embodiments. In the above embodiments, the detection sensor includes one upstream tape detection sensor (entrance sensor 51) located upstream in the tape feed direction relative to step sensor 52, but the present invention is not limited to this configuration. For example, in other embodiments, the detection sensor may include two or more upstream tape detection sensors.

[0053] In the above embodiment, the detection sensor includes two downstream tape detection sensors (tape end sensor 53, suction portion sensor 54) located downstream in the tape feed direction relative to step sensor 52, but is not limited to this configuration. For example, in other embodiments, the detection sensor may include one downstream tape detection sensor, or may include three or more downstream tape detection sensors.

[0054] In the above embodiment, the component supply feeder 30 is provided with a plurality of sensors 51-54 for detecting the carrier tapes t1, t2 on which the electronic components 3 are stored, but this configuration is not limited to this. For example, in other embodiments, the component supply feeder 30 may be provided with a detection sensor for detecting the electronic components 3 stored on the carrier tape.

[0055] In the above embodiment, the component supply feeder 30 is provided with an operation unit 46 having three buttons 46a, 46b, and 46c, but this configuration is not limited to this. For example, in other embodiments, the operation unit 46 may have one or two buttons, or may have four or more buttons. Furthermore, the operation unit 46 may have operation members other than buttons (for example, operation of a touch panel, etc.).

[0056] In the above embodiment, in an operation mode different from the normal operation, the button 46a (AUTO button) and the button 46b (feeder trace acquisition button) are pressed simultaneously, but this configuration is not limited to this. For example, in another embodiment, in an operation mode different from the normal operation, any one of the buttons 46a to 46c may be pressed for a long time (long press).

[0057] In the above embodiment, the display unit 47 is configured using an LED, but it may be configured using a member other than an LED (for example, a display having a display screen).

[0058] In the above embodiment, when the display unit 47 (LED) flashes, the CPU 42 reads the state transition information of each of the sensors 51-54 from the memory 43 in response to the operator's operation of the buttons 46a, 46b. However, this configuration is not limited to this. For example, in another embodiment, the CPU 42 may read the state transition information from the memory 43 in response to the operator's operation of a button after inserting the component supply feeder 30 into the feeder inspection jig 91. Alternatively, the CPU 42 may read the state transition information from the memory 43 in response to the operator's operation of a button when the display unit 47 flashes and after inserting the component supply feeder 30 into the feeder inspection jig 91. Furthermore, the CPU 42 may read the state transition information from the memory 43 in response to the operator's operation of a button when the display unit 47 flashes and after inserting the component supply feeder 30 into the feeder inspection jig 91. Furthermore, instead of being triggered by the operation of a button, the CPU 42 may read the state transition information from the memory 43 in response to the operator's insertion and connection of the communication connector of the component supply feeder 30 into the communication socket 93 of the feeder inspection jig 91.

[0059] In the above embodiment, an autoloading feeder (ALF) is used as the component supply feeder 30, but a feeder other than an ALF may also be used as the component supply feeder.

The technology described in the claims includes various modifications and variations of the specific examples exemplified above. The technical elements described in this specification or drawings exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.
