[0020] (Embodiment 1) Hereinafter, embodiments will be described based on the drawings.

[0021] [Overall Configuration] Figure 1 is a schematic diagram showing an example of a component mounting apparatus 100 according to Embodiment 1 of the present disclosure. Figure 2 is a block diagram of the component mounting apparatus 100 according to Embodiment 1. The X, Y, and Z directions in the figures represent the depth, width, and height directions of the component mounting apparatus 100.

[0022] The component mounting apparatus 100 shown in Figures 1 and 2 comprises a component supply device 1, a component mounting device 90, and a control unit 95. The component mounting apparatus 100 shown in Figure 1 further comprises a fixing base 80 for fixing the component supply device 1. Multiple component supply devices 1 can be arranged side by side in the Y direction on the fixing base 80.

[0023] The parts supply device 1 is a device that transports multiple parts A arranged in a line in the transport direction T and sequentially supplies the parts A to the parts supply position P1. The parts supply device 1 in this embodiment is a "bulk feeder" that takes out and transports parts A from a parts storage section 3 in which multiple parts A are stored individually.

[0024] The component mounting device 90 is a device that picks up component A supplied to component supply position P1 and mounts it on a substrate (not shown). The component mounting device 90 comprises a head 91 and a nozzle 92 attached to the head 91.

[0025] The head 91 is movable in the X, Y, and Z directions. For example, the head 91 can move above the component supply device 1 and above the substrate.

[0026] The nozzle 92 is a component that attracts and holds component A. The nozzle 92 attracts and picks up component A placed at component supply position P1. The nozzle 92 holds the picked-up component A and mounts it at a predetermined position on the substrate.

[0027] The control unit 95 is a component that controls the operation of the component mounting device 100. The control unit 95 is electrically connected to the component supply device 1 and the component mounting device 90 and controls various components. The control unit 95 can be composed of, for example, a microcontroller, CPU, MPU, GPU, DSP, FPGA, or ASIC. The functions of the control unit 95 may be composed of hardware alone, or they may be realized by a combination of hardware and software. The control unit 95 realizes predetermined functions by reading data and programs stored in a storage unit such as memory and performing various calculation processes.

[0028] The control unit 95 may be provided separately from the parts supply device 1 and the parts mounting device 90, or it may be provided integrally with the parts supply device 1 and the parts mounting device 90.

[0029] The parts supply device 1 shown in Figure 1 comprises a main body 2, a parts storage section 3, an attachment 4, and an alarm lamp 6. The parts supply device 1 further comprises a conveying force loading section 10 and an impact generating section 20.

[0030] The main body 2 is the main body portion of the parts supply device 1. The parts storage section 3 and attachment 4 are attached to the upper surface of the main body 2.

[0031] The parts storage section 3 is a component that stores multiple parts A. The parts storage section 3 is attached to the attachment 4 and supplies parts A to the parts transport path 5 of the attachment 4.

[0032] Attachment 4 is a component having a parts transport path 5 and is detachably attached to the main body 2. By providing the parts transport path 5 on attachment 4, the specifications of the parts transport path 5 can be easily changed in accordance with changes in the specifications of parts A.

[0033] As shown in Figure 1, the position where parts A are replenished from the parts storage section 3 to the parts transport path 5 is defined as the parts replenishment position P2. In the transport direction T, the parts replenishment position P2 is on the upstream side, and the parts supply position P1 is on the downstream side.

[0034] The notification lamp 6 is a component for notifying the worker. For example, the notification lamp 6 notifies an error if part A cannot be supplied properly to part supply position P1. Not limited to the notification lamp 6, any component that has the function of notifying the worker may be used.

[0035] The conveying force load unit 10 is a component that applies a conveying force to transport part A in the conveying direction T. The conveying force load unit 10 in this embodiment has an air supply mechanism that supplies positive pressure air and negative pressure air to the part transport path 5. Specifically, the conveying force load unit 10 has a positive pressure air supply path 12, a positive pressure air valve 13, a negative pressure air supply path 14, and a negative pressure air valve 15.

[0036] The positive pressure air supply passage 12 is a passage that supplies positive pressure air to the parts transport passage 5. In this embodiment, the positive pressure air supply passage 12 supplies positive pressure air near the parts replenishment position P2, generating an airflow from the parts replenishment position P2 toward the parts supply position P1. As a result, parts A are transported in the transport direction T. The positive pressure air supply passage 12 is composed of, for example, a tube, a pipe, or both. A positive pressure air valve 13 is located in the positive pressure air supply passage 12.

[0037] The positive pressure air valve 13 controls the air flowing through the positive pressure air supply passage 12. Specifically, the positive pressure air valve 13 controls the supply and cessation of air from the positive pressure air supply passage 12 to the parts transport passage 5. When the positive pressure air valve 13 is open, positive pressure air is supplied to the parts transport passage 5, and when the positive pressure air valve 13 is closed, the supply of positive pressure air to the parts transport passage 5 is stopped.

[0038] The negative pressure air supply passage 14 is a passage that supplies negative pressure air to the parts transport passage 5. In this embodiment, the negative pressure air supply passage 14 supplies negative pressure air near the parts supply position P1. This maintains parts A at the parts supply position P1, thereby enabling stable suction of parts A by the parts mounting device 90. The negative pressure air supply passage 14 is composed of, for example, a tube, a pipe, or both. A negative pressure air valve 15 is located in the negative pressure air supply passage 14.

[0039] The negative pressure air valve 15 controls the air flowing through the negative pressure air supply passage 14. Specifically, the negative pressure air valve 15 controls the supply and cessation of air from the negative pressure air supply passage 14 to the parts transport passage 5. When the negative pressure air valve 15 is open, negative pressure air is supplied to the parts transport passage 5, and when the negative pressure air valve 15 is closed, the supply of negative pressure air to the parts transport passage 5 is stopped.

[0040] The impact generating unit 20 is a component that applies impact to the parts transport path 5. By applying impact to the parts transport path 5, it is possible to clear any blockages that occur in the parts transport path 5 due to parts A. In this embodiment, the impact generating unit 20 is controlled by the control unit 95 to operate at predetermined timings.

[0041] In this embodiment, a cylinder is used as the impact generating unit 20. The cylinder is provided at a position close to the component supply position P1 in the main body 2, and generates vibration in the vicinity of the component supply position P1 of the main body 2. This vibration is transmitted from the main body 2 to the attachment 4, and an impact is applied to the component conveyance path 5.

[0042] In the component mounting apparatus 100 having the above configuration, the component mounting device 90 has a function of determining whether or not the nozzle 92 is normally sucking the component A. For example, the component mounting device 90 has a flow rate sensor that detects the flow rate of the negative pressure flow path inside the nozzle 92, and determines whether or not the component A is being sucked based on the detection result of the flow rate sensor. Alternatively, for example, the component mounting device 90 includes an imaging unit capable of imaging the tip of the nozzle 92, and determines whether or not the component A is being sucked based on the image captured by the imaging unit.

[0043] When the component mounting device 90 determines that the nozzle 92 is not normally sucking the component A, it transmits a suction error signal to the control unit 95. The suction error is presumably caused by a clogging of the component A in the component conveyance path 5. Therefore, the control unit 95 that has received the suction error signal operates the impact generating unit 20 of the component supply device 1. Thereby, an operation for eliminating the clogging of the component A in the component conveyance path 5, which is presumed to be the cause of the suction error, can be executed. The suction error signal functions as an impact request signal that requests an impact to the component conveyance path 5.

[0044] FIG. 3 is a flowchart showing an example of the operation executed by the component mounting apparatus 100 of this embodiment. Each step shown in FIG. 3 is executed by the control unit 95.

[0045] The processing of the flowchart shown in FIG. 3 is executed while a series of component mounting processes including (1) supply of the component A by the component supply device 1 and (2) suction of the component A by the component mounting device 90 and mounting on the substrate are being performed.

[0046] (1) The supply of component A by the component supply device 1 is executed by opening the positive pressure air valve 13 to send positive pressure air from the positive pressure air supply path 12 to the component conveyance path 5 and opening the negative pressure air valve 15 to send negative pressure air from the negative pressure air supply path 14 to the component conveyance path 5. As a result, component A is conveyed in the conveyance direction T from the component replenishment position P2 to the component supply position P1 in the component conveyance path 5, and the component A that has reached the component supply position P1 is maintained at the component supply position P1.

[0047] (2) The component mounting device 90 adsorbs component A at the component supply position P1 using the nozzle 92 and mounts the adsorbed component A on the substrate.

[0048] As shown in FIG. 3, the control unit 95 determines whether or not a component adsorption error has occurred (S1). Specifically, the control unit 95 determines whether or not a component adsorption error has occurred according to whether or not it has received an adsorption error signal from the component mounting device 90. The control unit 95 repeatedly executes step S1 as long as it does not receive an adsorption error signal from the component mounting device 90 (NO in S1).

[0049] When the control unit 95 receives an adsorption error signal from the component mounting device 90 (YES in S1), the control unit 95 starts an operation to eliminate the clogging of component A in the component conveyance path 5. Specifically, the control unit 95 stops the component conveyance (S2). That is, the positive pressure air valve 13 and the negative pressure air valve 15 are closed to stop the conveyance of component A in the component conveyance path 5.

[0050] The control unit 95 applies an impact to the component conveyance path 5 (S3). Specifically, the control unit 95 operates the impact generation unit 20 to apply an impact to the component conveyance path 5. Thereby, if clogging of component A has occurred in the component conveyance path 5, the clogging can be eliminated. By applying the impact after stopping the component conveyance in step S2, it is possible to suppress component A from popping out from the opening at the component supply position P1.

[0051] The operation pattern of the impact generating unit 20 in step S3 may be any pattern. Specifically, the number of times an impact is generated may be one or more times, and the time interval between impacts when multiple impacts are generated may be any interval (for example, every second or every few seconds).

[0052] After generating an impact, the control unit 95 resumes transporting the parts (S4). Specifically, the control unit 95 opens the positive pressure air valve 13 and the negative pressure air valve 15 to resume transporting parts A in the parts transport path 5 and supplies parts A to the parts supply position P1.

[0053] The control unit 95 resumes component suction (S5). Specifically, the control unit 95 sends a suction restart signal to the component mounting device 90, causing the component mounting device 90 to execute the interrupted mounting program. Upon receiving the suction restart signal, the component mounting device 90 moves the nozzle 92 toward the component supply position P1 and attempts to pick up component A.

[0054] The control unit 95 determines whether the adsorption was successful or not (S6). Specifically, the control unit 95 determines that the adsorption of component A was successful (YES in S6) depending on whether it receives an adsorption success signal from the component mounting device 90 or does not receive an adsorption failure signal. In this case, the process returns to step S1.

[0055] If the blockage of part A in the part transport path 5 is cleared by applying an impact to the part transport path 5 in step S3, then part A will be supplied normally to the part supply position P1, and the part mounting device 90 will successfully pick up part A (YES in S6).

[0056] On the other hand, if the blockage of part A in the part transport path 5 is not cleared, part A will not be supplied to the part supply position P1 properly, and the part mounting device 90 will fail to pick up part A (NO in S6). The control unit 95 receives a pick-up failure signal from the part mounting device 90, determines that part pick-up has failed, and proceeds to step S7.

[0057] The control unit 95 determines whether or not the determination of NO in step S6 is the Nth time (S7). Specifically, the control unit 95 has a value of N pre-stored in its memory, and it determines whether or not the determination of NO in step S6 is the Nth time. The value of N can be set to any value as long as it is a natural number of 1 or more.

[0058] If the number of times NO is determined in step S6 is N (YES in S7), the control unit 95 issues an error notification (S8). Specifically, the control unit 95 lights up the notification lamp 6 and stops the operation of the component mounting device 100. The notification from the notification lamp 6 allows the operator to recognize that the component jam clearing operation has failed. The operator then performs an operation to manually clear the jam of component A in the component transport path 5.

[0059] For example, if N is set to 1, and it is determined to be NO for the first time in step S6, it is determined to be the first time in step S7 (YES in S7), and the process proceeds to step S8.

[0060] For example, if N is set to 2 or greater, and the number of times NO is determined in step S6 (for example, the first time) is less than N (NO in S7), the control unit 95 executes steps S2 to S6 again. This causes the part jamming clearing operation using the impact generating unit 20 to be executed again. By setting the value of N to a desired value, it becomes possible to appropriately set the number of times the part jamming clearing operation using the impact generating unit 20 is performed.

[0061] Through the series of operations described above, if a jam occurs in the parts transport path 5 due to parts A, the impact generating unit 20 can be used to apply an impact to the parts transport path 5, thereby easily clearing the jam of parts A. This improves the supply efficiency of parts A.

[0062] In particular, when the component mounting device 90 receives an impact request signal, such as a suction failure signal, in response to the device failing to suction component A, the control unit 95 operates the impact generating unit 20, thereby clearing the jam of component A at an appropriate timing.

[0063] (Function / Effect 1) As described above, the component mounting apparatus 100 of this embodiment comprises a component supply device 1 that supplies component A to component supply position P1, a component mounting device 90 that picks up the component A supplied to component supply position P1 and mounts it on a substrate, and a control unit 95. The component supply device 1 comprises a component transport path 5 that transports component A to component supply position P1, and an impact generating unit 20 that applies impact to the component transport path 5. The control unit 95 generates impact in the impact generating unit 20 based on a predetermined impact request signal.

[0064] With this configuration, it becomes possible to clear any blockage of part A in the part transport path 5 at a desired timing, such as when a part suction error occurs, thereby improving the supply efficiency of part A.

[0065] Furthermore, in the component mounting apparatus 100 of this embodiment, the impact request signal is a signal (suction miss signal) transmitted in the component mounting apparatus 90 when the suction of component A is not detected. With this configuration, if a component suction miss occurs, the jam of component A in the component transport path 5 can be cleared, and the jam of component A can be cleared at an appropriate timing.

[0066] Furthermore, in the component mounting apparatus 100 of this embodiment, the component supply device 1 further includes a transport force loading unit 10 that applies a transport force to transport the component A. With this configuration, while transporting the component A using the transport force loading unit 10, an impact can be generated using an impact generating unit 20 separate from the transport force loading unit 10.

[0067] Furthermore, in the component mounting apparatus 100 of this embodiment, the control unit 95 stops the load of transport force by the transport force loading unit 10 based on a predetermined impact request signal (S2), and then generates an impact in the impact generating unit 20 (S3). With this configuration, it is possible to suppress the component A from flying out of the component transport path 5.

[0068] Furthermore, in the component mounting apparatus 100 of this embodiment, the control unit 95 restarts the load of transport force by the transport force loading unit 10 after generating an impact in the impact generating unit 20 (S4). With this configuration, component A can be sent to the component supply position P1 with the jamming of component A resolved.

[0069] Furthermore, in the component mounting apparatus 100 of this embodiment, the transport force loading unit 10 loads the transport force for transporting component A by supplying air to the component transport path 5. With this configuration, component A can be transported with a simple setup.

[0070] Furthermore, in the component mounting apparatus 100 of this embodiment, the control unit 95, after generating an impact in the impact generating unit 20, receives a predetermined impact request signal (NO in S6), and either generates another impact in the impact generating unit 20 (S3) or notifies an error (S8). With this configuration, appropriate processing can be performed if the jamming of component A has not been cleared.

[0071] As described above, the parts supply device 1 of this embodiment includes a parts transport path 5 for transporting parts A to a parts supply position P1, and an impact generating unit 20 for applying impact to the parts transport path 5, and generates impact in the impact generating unit 20 based on a predetermined impact request signal.

[0072] With this configuration, it becomes possible to clear any blockage of part A in the part transport path 5 at the desired timing, thereby improving the supply efficiency of part A.

[0073] (Embodiment 2) The component mounting apparatus 200 of Embodiment 2 will be described with reference to Figure 4. Descriptions that overlap with Embodiment 2 will be omitted as appropriate.

[0074] Figure 4 is a schematic diagram showing the component mounting apparatus 200 of Embodiment 2.

[0075] The component mounting apparatus 200 shown in Figure 4 includes a component supply device 205.

[0076] The parts supply device 205 includes a transport force loading unit 210 for loading the transport force of parts A in the parts transport path 5, instead of the impact generating unit 20 of Embodiment 1, as an impact generating unit for applying impact to the parts transport path 5.

[0077] The conveying force loading unit 210 of Embodiment 2 is similar to the conveying force loading unit 10 of Embodiment 1 in that it includes a negative pressure air supply passage 14 and a negative pressure air valve 15 as a mechanism for supplying negative pressure air, but it differs in the mechanism for supplying positive pressure air.

[0078] The conveying force load unit 210 includes a first positive pressure air supply passage 212, a second positive pressure air supply passage 214, a first regulator 216, a second regulator 218, and a switching valve 219 as a mechanism for supplying positive pressure air.

[0079] The first positive pressure air supply passage 212 and the second positive pressure air supply passage 214 are both passages for supplying positive pressure air to the parts transport passage 5, and are provided in parallel. The first positive pressure air supply passage 212 is provided with a first regulator 216, and the second positive pressure air supply passage 214 is provided with a second regulator 218.

[0080] The first regulator 216 is a component for adjusting the pressure of the positive air flowing through the first positive air supply passage 212 to a first pressure, and the second regulator 218 is a component for adjusting the pressure of the positive air flowing through the first positive air supply passage 212 to a second pressure.

[0081] In this embodiment, the second pressure is greater than the first pressure. First positive pressure air, having a first pressure relatively lower than the second pressure, is supplied from the first positive pressure air supply passage 212 to impose the normal transport force on part A in the part transport path 5. Second positive pressure air, having a second pressure relatively higher than the first pressure, is supplied from the second positive pressure air supply passage 214 to apply an impact to the part transport path 5 if part A becomes blocked in the part transport path 5.

[0082] The switching valve 219 is a valve that switches the supply and stop of positive pressure air to the parts transport path 5. The switching valve 219 switches between (1) a state in which positive pressure air from the first positive pressure air supply path 212 is supplied to the parts transport path 5, (2) a state in which positive pressure air from the second positive pressure air supply path 214 is supplied to the parts transport path 5, and (3) a state in which the supply of positive pressure air to the parts transport path 5 is stopped.

[0083] The component mounting apparatus 200 of Embodiment 2, having the above configuration, executes the processing shown in the flowchart in Figure 3, similar to the component mounting apparatus 100 of Embodiment 1.

[0084] Specifically, unless a component suction error signal is received from the component mounting device 90 (NO in S1), step S1 is repeatedly executed, during which time the component supply device 1 supplies component A and the component mounting device 90 picks up component A and mounts it to the substrate. When the component supply device 1 supplies component A, positive pressure air at the first pressure is supplied to the component transport path 5 through the first positive pressure air supply path 212 shown in Figure 4.

[0085] When the control unit 95 receives a component suction error signal from the component mounting device 90 (YES in S1), it operates the switching valve 219 to stop the supply of positive pressure air to the first positive pressure air supply passage 212, thereby stopping component transport (S2).

[0086] The control unit 95 further operates the switching valve 219 to supply positive pressure air from the second positive pressure air supply passage 214 to the parts transport passage 5, thereby applying an impact to the parts transport passage 5 (S3). By switching from positive pressure air at the first pressure to positive pressure air at the second pressure and relatively increasing the pressure of the positive pressure air, an impact can be directly applied to the inside of the parts transport passage 5.

[0087] The impact generation operation pattern in step S3 may be any pattern.

[0088] According to the operation described above, the transport force loading unit 210 can be used as an impact generating unit, and jamming of part A can be resolved with a simple configuration.

[0089] (Function / Effect 2) In the component mounting apparatus 200 of this embodiment, the component supply apparatus 205 is equipped with a transport force loading unit 210 as an impact generating unit, which loads a transport force to transport component A by supplying air to the component transport path 5, and the control unit 95 applies an impact to the component transport path 5 by relatively increasing the pressure of the positive pressure air supplied by the transport force loading unit 210.

[0090] With this configuration, the transport force loading section 210 can also function as the impact generating section, and jamming of component A can be resolved with a simple configuration.

[0091] (Embodiment 3) The component mounting apparatus 300 of Embodiment 3 will be described with reference to Figures 5 and 6. Descriptions that overlap with Embodiment 2 will be omitted as appropriate.

[0092] Figure 5 is a schematic diagram showing the component mounting apparatus 300 of Embodiment 3. Figure 6 is a flowchart showing an example of the operation performed by the component mounting apparatus 300 of Embodiment 3.

[0093] The component mounting apparatus 300 shown in Figure 5 includes a component supply device 305.

[0094] The parts supply device 305 includes a parts detection unit 310 that detects the presence or absence of parts A at a predetermined position in the parts transport path 5. The control unit 95 operates the impact generating unit 20 based on the detection result of the parts detection unit 310, instead of receiving a suction error signal from the parts mounting device 90.

[0095] The component detection unit 310 in this embodiment is provided near the component supply position P1 and detects the presence or absence of component A at the component supply position P1. The component detection unit 310 is, for example, an optical sensor. The component detection unit 310 may also detect the presence or absence of component A at a position different from the component supply position P1, and may also detect the presence or absence of component A using a principle different from that of an optical sensor.

[0096] As shown in Figure 6, while a series of component mounting operations are being performed, the control unit 95 determines whether or not component A is present at component supply position P1 based on the detection result of the component detection unit 310 (S11).

[0097] If the control unit 95 determines that part A is present at part supply position P1 (YES in S11), it repeatedly executes step S11. That is, it continues the series of part mounting operations. On the other hand, if the control unit 95 determines that part A is not present at part supply position P1 (NO in S11), it executes steps S2 to S4, similar to the part mounting device 100 of Embodiment 1. This stops the part transport, then activates the impact generating unit 20 to apply an impact to the part transport path 5, thereby clearing any jamming of part A, and then resumes part transport.

[0098] The control unit 95 determines whether or not part A is present at part supply position P1 (S11). If the blockage of part A in the part transport path 5 is cleared by the impact generated in step S3, part A is supplied to part supply position P1 normally, and therefore it is determined that part A is present at part supply position P1 (YES in S12). In this case, a suction restart signal is sent to the part mounting device 90, causing the part mounting device 90 to restart suction of the part (S13).

[0099] If the blockage of component A in the component transport path 5 is not cleared by the impact generated in step S3, component A will not be supplied to the component supply position P1 properly, and it will be determined that there is no component A at the component supply position P1 (NO in S12). In this case, the process proceeds to step S7, similar to the component mounting device 100 of Embodiment 1.

[0100] According to the operation described above, by operating the impact generating unit 20 based on the detection result of the part detection unit 310, the impact generating unit 20 can be operated to clear the jam of part A without receiving a suction missignation signal from the part mounting device 90. In this way, the determination of whether or not a jam of part A has occurred in the part transport path 5 and the operation to clear the part jam can be completed and executed by the part supply device 1 and the control unit 95.

[0101] (Function / Effect 3) In the component mounting apparatus 300 of this embodiment, the component supply apparatus 305 further includes a component detection unit 310 that detects the presence or absence of component A at a predetermined position in the component transport path 5, and the impact request signal is a signal transmitted in response to the component detection unit 310 not detecting component A.

[0102] With this configuration, the impact generating unit 20 can be activated when part A is not in a predetermined position on the part transport path 5.

[0103] (Other) Although the present invention has been described above with reference to the embodiments described above, the present invention is not limited to the embodiments described above. For example, in embodiments 1 and 3, a case in which a cylinder is used as the impact generating unit 20 was described, but the present invention is not limited to such a case, and any configuration may be used as long as an impact can be applied directly or indirectly to the parts transport path 5.

[0104] Furthermore, while Embodiment 2 described a case in which the pressure of the positive-pressure air is changed using two types of positive-pressure air supply lines 212, 214 and two types of regulators 216, 218, the invention is not limited to this case. For example, if a variable-pressure electro-pneumatic regulator is used, only one type of positive-pressure air supply line and one type of regulator may be used.

[0105] While this disclosure is adequately described in relation to preferred embodiments with reference to the accompanying drawings, various variations and modifications will be obvious to those skilled in the art. Such variations and modifications should be understood to be included within the scope of this disclosure as defined by the attached claims. Furthermore, variations in combinations and sequences of elements in each embodiment can be realized without departing from the scope and spirit of this disclosure.

[0106] Furthermore, by appropriately combining any of the above embodiments and various modifications, the effects of each can be achieved.
