Description

TECHNICAL FIELD The present invention relates to a re-injection support device that supports the work of re-introducing a workpiece extracted from the middle of a production line into the production line.

The component mounting line is a production line that connects multiple production devices such as printing equipment and component mounting equipment.The component mounting line is a production line that connects multiple production devices such as printing equipment and component mounting equipment.The component mounting line is a production line that connects multiple production equipment such as printing equipment and component mounting equipment. By performing work processes such as mounting, a mounted board with components mounted on the board is produced. An inspection device is installed in the component mounting line, and the quality of the work results is determined for predetermined inspection items for the board after each work process (for example, see Patent Document 1).

In the component mounting line described in Patent Document 1, when an inspection device determines that a board needs to be corrected, the board is extracted from a board transfer device installed downstream of the inspection device, and the necessary correction work is performed. After that, an off-line correction process is executed in which the board is reinserted into the board transfer device installed upstream of the inspection device. In the offline correction process, when it is determined that a board needs to be corrected, a board transfer device that removes the board and a board transfer device that reloads the board are identified. Then, the locking mechanism of the door member of only the identified substrate transfer device is released, and the substrate can be taken out and reinserted. This prevents erroneously removing a different board or erroneously reinserting a board into a different board transfer device.

JP2009-21466A

By the way, boards that have been removed from the component mounting line after being determined by the inspection equipment to require confirmation may be re-inserted depending on various circumstances such as the details of the board modification work or the amount of time that has passed since the board was removed. It is necessary to change the location or cancel re-injection. However, in the conventional technology including Patent Document 1, measures are taken to prevent erroneous operations on the premise that the board extracted from the component mounting line is subjected to predetermined processing and then reintroduced to the component mounting line. There was room for further improvement in order to appropriately prevent erroneous operations depending on the situation.

An embodiment of the present invention will be described with reference to the drawings. First, the configuration of the component mounting line 1 will be explained with reference to FIG. The component mounting line 1 is a production line that has the function of mounting components on a board (work) to produce a mounted board. The component mounting line 1 includes a loader M1, a first conveyor M2, a printing device M3, a print inspection device M4, a second conveyor M5, from the upstream side (left side in the paper) to the downstream side (right side in the paper) in the board transport direction. Production equipment such as component mounting devices M6 to M8, third conveyor M9, mounting inspection device M10, fourth conveyor M11, reflow device M12, fifth conveyor M13, post-reflow inspection device M14, sixth conveyor M15, and unloader M16 are connected in series. is connected to.

Each production device is connected to an information processing device 3 via a wired or wireless communication network 2. Information identifying the board being worked on and the work position, information on the work performed on the board, etc. are transmitted from each production device to the information processing device 3, which is a computer. Further, the information processing device 3 stores information on a production program currently applied to the component mounting line 1, and the like.

In FIG. 1, a loader M1 supplies a substrate B (see FIG. 3) to downstream production equipment. The printing device M3 performs a solder printing operation of screen printing solder for joining components onto the board B. The print inspection device M4 performs a print inspection operation to inspect the state of solder printed on the board B. The component mounting devices M6 to M8 perform a component mounting operation of mounting components onto the board B on which solder is printed.

The mounting inspection device M10 performs a mounting inspection work that inspects the state of components mounted on the board B. The reflow device M12 heats the board B to melt and harden the solder, and performs a reflow operation in which the electrodes of the board B and the terminals of the components are soldered together. The post-reflow inspection device M14 performs a post-reflow inspection work that inspects the state of components on the board B after reflow. The unloader M16 collects the substrate B transported from the upstream side.

In FIG. 1, a first conveyor M2, a second conveyor M5, a third conveyor M9, a fourth conveyor M11, a fifth conveyor M13, and a sixth conveyor M15 transport substrates B carried out from upstream production equipment to downstream It is equipped with a conveyor that transports it to production equipment. All or some of these conveyors have a structure that allows the board B to be removed from the transport conveyor and the board B to be reinserted into the transport conveyor. Furthermore, the conveyor capable of extracting and reinserting the board B has functions corresponding to a board extracting process and a board reinserting process in which the extracted board B is reinjected into the component mounting line 1, which will be described later.

In addition, the first conveyor M2 reads a board label Lb (see FIG. 3) such as a bar code or two-dimensional code attached to the board B transported by the transport conveyor, and uses a board ID (work identification) to identify the board B. It is equipped with a built-in reader (not shown) that reads the information. The first conveyor M2 reads the board ID from the board label Lb of the board B supplied from the loader M1, and transmits it to the information processing device 3.

In the component mounting line 1, a reader 4 is used that reads a board label Lb attached to a board B and a device label Lm (see FIG. 2) such as a bar code or two-dimensional code attached to a production device. A reading unit 4a included in the reader 4 reads the board label Lb to recognize the board ID, and reads the device label Lm to recognize the device ID that specifies the production device. The recognized board ID and device ID are wirelessly transmitted to the production device or information processing device 3. Further, the reader 4 wirelessly receives various information transmitted from the production device or the information processing device 3 and displays it on the display screen 4b. In addition to being carried by a worker, a plurality of readers 4 are installed near the production equipment (see FIG. 2).

Next, with reference to FIGS. 2 and 3, the configurations of inspection devices such as the print inspection device M4, the mounting inspection device M10, and the post-reflow inspection device M14 will be described. The print inspection device M4, the mounting inspection device M10, and the post-reflow inspection device M14 inspect a board B after solder printing, a board B after mounting components, and a board B after reflow, and are equipped with a camera specialized for inspection purposes, It has its own inspection head 11 with sensors, lighting, etc. Note that in each inspection device, parts related to transporting and reinserting the substrate B, such as the opening/closing cover 6 and the transport conveyor 9, have the same configuration. The on-board inspection device M10 will be described below as an example. In the mounted inspection device M10, a device label Lm is attached to the front surface where an operator works. Furthermore, a display section 5 that displays various information such as inspection results by the on-board inspection device M10 is arranged on the front side of the on-board inspection device M10.

In FIG. 3, the mounting inspection device M10 is equipped with an opening/closing cover 6 on the front, and an opening/closing cover locking section 7 and an opening/closing cover detecting section 8 inside. When the opening/closing cover lock part 7 is in the locked state with the opening/closing cover 6 closed, the opening/closing cover 6 is locked so that it cannot be opened or closed. Moreover, when the opening/closing cover lock part 7 is in the unlocked state, the operator can freely open/close the opening/closing cover 6. The opening/closing cover detection unit 8 is a sensor such as a microswitch, and detects whether the opening/closing cover 6 is in a closed state or an open state.

A pair of conveyors 9 are arranged inside the loading inspection device M10. The conveyor 9 receives the substrate B carried out from the third conveyor M9 on the upstream side, conveys it to the inspection work position P1, and carries out the inspected substrate B to the fourth conveyor M11 on the downstream side. The conveyor 9 includes a substrate detection unit 10 such as an optical sensor that detects the substrate B conveyed to the inspection work position P1.
is located. When the conveyor 9 stops the substrate B at the inspection work position P1, when the substrate detection section 10 detects the substrate B being conveyed, the conveyance of the substrate B is stopped. The operator can open the open/close cover 6 and reinsert the board B into the inspection work position P1. That is, the inspection work position P1 in the mounted inspection apparatus M10 is a work position where the board B can be reinserted.

In FIG. 3, an inspection head 11 is installed inside the mounted inspection device M10. The inspection head 11 includes a camera for inspecting the state of the components mounted on the board B, a 3D sensor, and lighting for imaging. The mounting inspection device M10 determines the presence or absence of components and the mounting state of the components based on the inspection results obtained by the inspection head 11.

Next, with reference to FIGS. 2 and 3, the configurations of the second conveyor M5, fourth conveyor M11, and sixth conveyor M15 corresponding to the extraction process of the substrate B will be described. Note that the second conveyor M5, the fourth conveyor M11, and the sixth conveyor M15 have the same configuration. The fourth conveyor M11 located downstream of the mounting inspection device M10 will be described below as an example. In the fourth conveyor M11, a device label Lm is attached to the front surface where an operator works. Furthermore, a display unit 12 is arranged in front of the fourth conveyor M11 to display various information such as instructions for substrate extraction processing and substrate re-insertion processing in the fourth conveyor M11.

In FIG. 3, the fourth conveyor M11 includes an opening/closing cover 13 on its upper surface, an opening/closing cover locking section 14, and an opening/closing cover detecting section 15 inside. The functions of the opening/closing cover 13, opening/closing cover locking section 14, and opening/closing cover detection section 15 are the same as those of the opening/closing cover 6, opening/closing cover locking section 7, and opening/closing cover detecting section 8 included in the on-board inspection device M10, and detailed explanations are omitted. do.

A pair of transport conveyors 16 are arranged inside the fourth conveyor M11. The transport conveyor 16 receives the substrate B carried out from the upstream mounting inspection device M10, transports it to the sampling operation position P2, and carries out the substrate B at the sampling operation position P2 to the downstream reflow apparatus M12. A substrate detection unit 17 such as an optical sensor is arranged on the conveyor 16 to detect the substrate B conveyed to the sampling work position P2.

When the conveyor 16 stops the substrate B at the extraction work position P2, when the substrate detection section 17 detects the substrate B being conveyed, the conveyance of the substrate B is stopped. When the substrate sampling process and the substrate reinsertion process are not performed, the conveyor 16 carries out the substrate B received from the mounting inspection apparatus M10 to the reflow apparatus M12 without stopping it at the sampling operation position P2.

In FIG. 1, the printing device M3 and the component mounting devices M6 to M8 are equipped with a conveyor having a working position, an opening/closing cover, and an opening/closing cover lock part, and the board B can be reloaded. That is, the component mounting line 1 includes a first conveyor M2, a printing device M3, a printing inspection device M4, a second conveyor M5, component mounting devices M6 to M8, a third conveyor M9, a mounting inspection device M10, a fourth conveyor M11, The fifth conveyor M13, the post-reflow inspection device M14, and the sixth conveyor M15 are re-input locations where the board B can be re-injected into the component mounting line 1 (production line).

Next, with reference to FIG. 4, the configuration of the information processing system of the component mounting line 1 will be described. Here, the configuration related to the board extraction process and the board re-insertion process of the component mounting line 1 will be described. The information processing device 3 stores sampled board information 20 and board location information 21. The sampled board information 20 (sampled work information) includes the board ID (workpiece identification information) of the board B (workpiece) sampled from the middle of the component mounting line 1 (production line), the time at which it was sampled, and the location where it was sampled ( information about the work performed on the component mounting line 1, and information about the production program that was being applied on the component mounting line 1 when the sample was extracted. Sampling board information including this information is automatically created by a board sampling process described later.

Further, when repair work is performed on the extracted board B, information on the work performed on the board B (work) after being extracted can be added to the extracted board information 20. Additionally, as a result of visual inspection and repair work, if it is determined that remounting is required using component mounting devices M6 to M8 rather than manually, information on the components that require remounting shall also be added to the sampled board information 20. Can be done. These pieces of information are added by the operator who has performed the repair work using an input device (not shown) such as a keyboard or an information terminal. The information processing device 3 replies with the relevant information included in the sampled board information 20 in response to an inquiry from the production device.

In FIG. 4, the board location information 21 stores the location of each board B in the component mounting line 1 (production line) in association with the board ID. Specifically, when the board ID of the board B supplied from the loader M1 is read by the built-in reader of the first conveyor M2, the information is recorded in the board location information 21. Thereafter, when the substrate B is transported from each production device to the downstream production device, the substrate location information 21 is updated to new information. That is, the location of board B is updated with new information. Furthermore, information on the board B extracted by the board extraction process is deleted from the substrate location information 21. Furthermore, when the board B is reinserted in the board re-insertion process, information on the reinserted board B is added to and updated to the substrate location information 21.

In FIG. 4, the fourth conveyor M11 includes a network communication section 30, a conveyance processing section 31, a sampling processing section 32, a reinsertion processing section 33, and a wireless communication section 35. The network communication unit 30 is a communication interface, and transmits and receives data between the information processing device 3 and other production devices via the communication network 2. The wireless communication unit 35 is a wireless communication device, and transmits and receives data to and from the reader 4 wirelessly. Note that the reader 4 may be connected to the fourth conveyor M11 by wire. Further, the reader 4 may transmit and receive data via the fourth conveyor M11, a wireless communication device included in the information processing device 3, and the communication network 2.

In FIG. 4, the transport processing unit 31 receives the inspection results of the board B by the upstream mounting inspection device M10, the detection results of the board B by the board detection unit 17, the commands from the sampling processing unit 32, and the input processing unit 33. Based on the command, the transport conveyor 16 is controlled to transport the substrate B. Specifically, if the substrate B has a good inspection result by the mounting inspection device M10, the transport processing section 31 transports the received substrate B to the reflow device M12 without stopping it at the sampling work position P2.

If the inspection result by the mounting inspection device M10 is bad and the sampling processing section 32 has issued a sampling instruction for the substrate B, the transport processing section 31 stops the received substrate B at the sampling operation position P2. When stopped at the sampling work position P2, a substrate stop completion signal is output to the sampling processing section 32. Further, when receiving a re-insertion preparation command from the re-insertion processing section 33, the transport processing section 31 transports the substrate B located at the extraction work position P2 to the downstream side to free up the extraction operation position P2, and then performs the re-insertion processing. A board unloading completion signal is output to the unit 33. Furthermore, when the transport processing unit 31 causes the substrate B on the fourth conveyor M11 to be carried out to the reflow apparatus M12, it transmits a notification to that effect to the information processing apparatus 3.

In FIG. 4, the sampling processing unit 32 selects a board B that is judged to need to be sampled in order to determine whether visual inspection or repair is necessary, based on the inspection results by the upstream inspection device (onboard inspection device M10). (Hereinafter, referred to as a "substrate requiring confirmation") is caused to perform a sampling process for the operator to remove it from the fourth conveyor M11. Further, the sampling processing section 32 includes a fourth conveyor M.
After the board requiring confirmation is removed from M11, a post-extracting operation restart process is executed to restart the operation of the fourth conveyor M11.

In the sampling process, when the confirmation-required board is delivered to the conveyor 16 from the upstream side, the sampling processing unit 32 transmits a command to prohibit the removal of the board B to the upstream device (here, the mounting inspection device M10), The confirmation board is stopped at the extraction work position P2. Further, the sampling processing unit 32 causes the display unit 12 to display that a board requiring confirmation has occurred (see FIG. 8(a)).

Note that the sampling processing section 32 may display, via the wireless communication section 35, on the display screen 4b of the reader 4 carried by the worker, that a board requiring confirmation has occurred. In this case, the sampling processing unit 32 also displays on the display screen 4b the location (here, the fourth conveyor M11) from which the confirmation-required board is extracted. An example in which the sampling processing section 32 causes the display section 12 to display various information will be described below.

When the board requiring confirmation has stopped at the extraction work position P2, the extraction processing section 32 unlocks the opening/closing cover lock section 14 (releases the safety device), and displays a message on the display section 12 to the effect that the board requiring confirmation is ready to be extracted. (See FIG. 8(b)).

In the operation restart process, the sampling processing unit 32 causes the display unit 12 to display a screen for inputting whether or not to return the extracted board requiring confirmation to the fourth conveyor M11 (see FIG. 9(a)). If the board requiring confirmation is not returned, the sampling processing section 32 determines whether or not the board B is present at the sampling operation position P2 when the opening/closing cover 13 is closed. If there is a substrate B at the sampling operation position P2, the sampling processing section 32 causes the display section 12 to display a warning that there is an unknown substrate B (see FIG. 10(b)). If there is no board B at the sampling work position P2, the sampling processing section 32 locks the opening/closing cover lock section 14 (enables the safety device), sends a command to start unloading the substrate B to the upstream device, and starts operation. to be restarted.

When returning a board requiring confirmation, upon receiving the board ID read by the reading unit 4a of the reader 4, the extraction processing unit 32 determines that the board ID transmitted from the reader 4 matches the board ID of the board requiring confirmation that was extracted. Determine whether or not. If the board IDs do not match, the extraction processing unit 32 causes the display unit 12 to display a warning that the board cannot be reinserted (see FIG. 9(b)).

When the board IDs match, when the open/close cover 13 is closed, the sampling processing section 32 determines whether the board B is present at the sampling operation position P2. If the board B is not present at the sampling position P2, the sampling processing unit 32 causes the display unit 12 to display a warning that the board requiring confirmation has not been returned to the sampling position P2 (see FIG. 10(a)). When the substrate B is present at the extraction work position P2, the extraction processing section 32 locks the opening/closing cover locking section 14, sends a command to start unloading the substrate B to the upstream device, and restarts the operation. In this way, the fourth conveyor M11 (production device) and the reader 4 constitute a substrate extraction device 40 that extracts a substrate (workpiece) requiring confirmation from the middle of the production line.

In FIG. 4, the re-insertion processing section 33 executes a re-insertion process for reintroducing the board (workpiece) requiring confirmation that has been extracted from the middle of the production line (component mounting line 1) into the production line. Further, the re-input processing unit 33 includes a re-input permission determination unit 34 as an internal processing unit. Hereinafter, the re-entered board requiring confirmation will be referred to as a "re-entered board." In the re-loading process, the re-loading processing unit 33 displays on the display screen 4b of the reader 4 via the wireless communication unit 35 that the board ID (work identification information) of the re-loading board is to be read (see FIG. 13(a)). .

Upon receiving the board ID read by the reading unit 4a of the reader 4, the re-input possibility determining unit 34 determines whether the re-input board can be re-introduced to the production line based on the extracted board information 20 (sampled work information). to judge. In other words, the re-input possibility determining unit 34 determines based on the board ID (workpiece identification information) whether the re-input board (work) to which the board ID is attached can be re-introduced to the production line.

Specifically, the re-insertion permission determination unit 34 determines the time (elapsed time) that has passed since the re-inserted board was removed from the production line, based on the time when the re-inserted board was removed, which is included in the extracted board information 20. If the predetermined time has not exceeded or the return deadline has not passed, it is determined that the item can be re-inserted. The predetermined elapsed time and return deadline are set based on the allowable time from when solder is screen printed on the board B in the printing device M3 to when the mounting of components is finished. This makes it possible to prevent the board from being reintroduced to the production line, where the solder may dry and lead to defective mounting.

Further, the re-insertion possibility determining unit 34 determines, based on the production program at the time when the re-inserted board is extracted, which is included in the extracted board information 20, that the production program currently applied to the production line is compatible with the re-inserted board. If so, it is determined that re-input is possible. For example, if a setup change is made to change the type of mounting board to be produced on the production line after the re-input board is removed, the production program may be changed. If the production program has been changed, the re-input possibility determining unit 34 determines that re-input is not possible. As a result, it is possible to prevent the production line from stopping due to the inability to work on the reinserted board, or to prevent different parts from being mounted on the reinserted board.

When the re-insertion determination unit 34 determines that re-insertion is not possible, the re-insertion processing unit 33 displays a warning on the display screen 4b of the reader 4 to the effect that the re-inserted board whose board ID has been read cannot be re-inserted. 4 on the display screen 4b (see FIG. 13(b)). When the re-insertion possibility determination unit 34 determines that re-insertion is possible, the re-insertion processing unit 33 displays on the reader 4 the re-insertion location (production equipment to be re-inserted) of the re-inserted board based on the extracted board information 20. It is displayed on the screen 4b (see FIG. 14(a)). That is, the re-insertion processing unit 33 notifies the re-insertion location of the re-inserted board (work) to which the board ID is attached based on the board ID (work identification information).

The re-insertion processing unit 33 includes information on the location (production equipment) from which the re-inserted board was extracted, which is included in the extracted board information 20, information on the work performed on the re-inserted board (workpiece) after it was extracted, and information on the need for re-insertion. The re-input location (production equipment) is determined based on information about the parts. Furthermore, if there are multiple places where the product can be re-inserted, the re-insertion processing unit 33 notifies the plurality of re-insertion locations. In addition to displaying the re-input location on the reader 4, the re-input processing unit 33 transmits a re-input location notification command to the production equipment that is the re-input location, and displays the display unit of the production equipment (for example, the The display unit 12) of the fourth conveyor M11 or an indicator light (not shown) may be blinked to notify that the production equipment is at the re-input location.

After notifying the reloading location, the reloading processing unit 33 receives the device ID (reloading location information) read by the reading unit 4a of the reader 4, and then converts the received device ID to the device ID of the notified reloading location. Determine whether it matches or not. If the device IDs do not match, the re-insertion processing section 33 displays a warning to the effect that the re-insertion location is inappropriate on the display screen 4b of the reader 4 (see FIG. 14(b)). If the device ID matches any of the re-input locations, the re-input processing unit 33 transmits a re-input preparation command to the production device at the matched re-input location.

Here, using the fourth conveyor M11 as an example, the re-input acceptance process executed by the production device that has received the re-input preparation command will be described. Upon receiving the reinsertion preparation command, the fourth conveyor M11 transmits a command to prohibit the removal of the substrate B to the upstream device (here, the mounting inspection device M10). When the fourth conveyor M11 carries out the substrate B in the apparatus to the downstream side and becomes able to receive the reinserted substrate at the extraction work position P2, the fourth conveyor M11 unlocks the opening/closing cover lock part 14. This completes the reloading acceptance process, and the fourth conveyor M11 transmits a reloading preparation completion report to the reloading processing unit 33 that sent the reloading preparation command.

Upon receiving the re-insertion preparation completion report, the re-insertion processing section 33 causes the reading section 4a of the reader 4 to display that the re-insertion preparation is complete (see FIG. 15(a)). Note that the re-insertion processing section 33 may display on the display section of the re-insertion location that preparations for re-insertion have been completed. In this manner, the re-input processing unit 33 instructs the re-input location (production equipment) to prepare to accept the re-input of the re-input board (workpiece), and notifies the re-input processing unit 33 when the re-input preparation is completed. Further, the re-loading processing unit 33 determines that the preparation for re-loading is completed when the board B (work) is taken out from the re-loading location and the state prohibits the board B from being carried into the re-loading location. I judge that.

In the production equipment that is the re-input location, for example, the fourth conveyor M11, after the preparation for re-input is completed, the operator opens the opening/closing cover 13 of the re-input location, and then, when the opening/closing cover 13 is closed, the re-input Post-operation restart processing is executed. In the operation restart processing after reinsertion, first, it is determined whether or not there is a reinsertion board at the extraction work position P2. If there is no re-inserted board at the extraction work position P2, a warning to the effect that no re-inserted board has been reinserted into the extraction work position P2 is displayed on the display unit 12 (see FIG. 15(b)). When the substrate B is present at the sampling operation position P2, the fourth conveyor M11 locks the opening/closing cover lock portion 14, transmits a command to start carrying out the substrate B to the upstream device, and restarts the operation.

In this way, the reader 4 checks the workpiece identification information (board ID) attached to the board requiring confirmation and the work scheduled to be re-injected (re-input board) and the re-input location (production equipment) on the production line (component mounting line 1). This is information acquisition means for acquiring re-insertion location information (device ID) attached to the device. The information acquisition means and the sampling processing unit 32 constitute a sampling support device that supports the work of extracting a board (workpiece) requiring confirmation from the middle of the production line. Further, the re-loading processing unit 33 makes it possible to re-load the work from the re-loading location specified by the re-loading location information, on the condition that the information acquisition means acquires the workpiece identification information and the re-loading location information. .

In this way, the reader 4 and the fourth conveyor M11, which are information acquisition means, constitute a re-injection support device that supports the work of re-introducing a workpiece extracted from the middle of the production line into the production line. Further, the second conveyor M5 and the sixth conveyor M15, which have the same configuration and function as the fourth conveyor M11, and the reader 4 attached thereto also constitute a re-insertion support device. Note that the information acquisition means (reader 4) may be provided for each re-injection support device, but it can also be shared by a plurality of re-injection support devices or shared with other devices.

Next, the substrate extraction operation in the substrate extraction device 40 (extraction support device) will be explained along the flowchart of FIG. 5. In the substrate extracting operation, the transport processing unit 31 of the substrate extracting device 40 transports the substrate B received from the upstream side to the extracting work position P2 (ST1 is executed until ST2 is reached). If the board B that has arrived at the sampling work position P2 is a board that requires confirmation and has a defective inspection result in the inspection device (confirmation required in ST3), the sampling processing section 32 executes a substrate sampling process (ST4).

If the board B that has arrived at the sampling work position P2 is inspected by the inspection device as a good product and sampling is not necessary (ST3 is unnecessary), the transport processing unit 31 moves the board B to the downstream side without stopping at the sampling work position P2. Have it removed. After the board B is unloaded from the board extraction device 40, if the production of the mounted board is not completed (No in ST5), the process returns to (ST1) and transport of the next board B is executed.

Next, the details of the substrate extraction process (ST4) in the substrate extraction device 40 will be explained along the flowcharts of FIGS. 6 to 7 and with reference to FIGS. 8 to 10. In FIG. 6, when the board requiring confirmation reaches the sampling work position P2 and the board transport is stopped (ST11), the sampling processing unit 32 sends the board extraction notification screen 50 (FIG. 8(a)) to the board extraction device 40. (ST12). When the "OK" button 50a is operated on the confirmation board generation notification screen 50 (response is received in ST13), the extraction processing unit 32 releases the safety device of the board extraction device 40 (ST14). As a result, the opening/closing cover 13 of the board extraction device 40 can be opened and closed.

Next, the sampling processing unit 32 displays the board ID reading request screen 51 (FIG. 8(b)) on the display device (ST15). When the operator opens the opening/closing cover 13, takes out the board requiring confirmation, and obtains the board ID using the reader 4 (obtaining the board ID in ST16), the information processing device 3 creates the extracted board information 20 regarding the board requiring confirmation that has been extracted. (ST17).

In FIG. 7, the sampling processing unit 32 then displays the operation restart confirmation screen 52 (FIG. 9(a)) on the display device (ST18). When the "return board" button 52a is operated on the operation restart confirmation screen 52 (return the board in ST19) and obtain the board ID (obtain the board ID in ST20), the sampling processing unit 32 returns the obtained board ID. Based on this, it is determined whether the board B can be reloaded (ST21).

If the obtained board ID does not match the extracted board requiring confirmation and it is determined that re-insertion is not possible (impossible in ST21), the extraction processing unit 32 displays the extraction-re-insertion impossible warning screen 53 (FIG. 9(b)). ) is displayed on the display device (ST22). When the "try again" button 53b is operated on the extraction/re-insertion impossible warning screen 53 (redo in ST23), the process returns to (ST18) and the operation restart confirmation screen 52 is displayed on the display device.

The obtained board ID matches the extracted board requiring confirmation and it is determined that re-insertion is possible (possible in ST21), or the "Continue" button 53a is operated on the removal-re-insertion impossible warning screen 53 (continue in ST23). (possible), then when the opening/closing cover 13 is closed (cover closed in ST24), the sampling processing unit 32 determines whether or not the substrate B is present at the sampling operation position P2 (ST25). If the substrate B has not been returned to the extraction work position P2 (no substrate in ST25), the extraction processing unit 32 causes the display device to display a no-substrate warning screen 54 (FIG. 10(a)) (ST26). When the "try again" button 54b is operated on the no-board warning screen 54 (redo in ST27), the process returns to (ST18) and the operation restart confirmation screen 52 is displayed on the display device.

In FIG. 7, when the "Do not return the board" button 52b is operated on the operation restart confirmation screen 52 (do not return the board in ST19) and the opening/closing cover 13 is closed (cover is closed in ST28), the extraction processing unit 32 , it is determined whether the board B is present at the sampling work position P2 (ST29). If there is a board B that should not be present at the sampling work position P2 (substrate present in ST29), the sampling processing unit 32 causes the display device to display an unknown substrate presence warning screen 55 (FIG. 10(b)) (ST30). When the board B is removed from the sampling work position P2 and the "resume" button 55a is operated on the unknown board warning screen 55, the process returns to (ST18) and the operation restart confirmation screen 52 is displayed on the display device.

When returning the board (returning in ST19), if a board requiring confirmation is returned to the extraction work position P2 (there is a board in ST25), or if the "Continue" button 54a is operated on the no-board warning screen 54 (continue in ST27). ), if the board is not returned (not returned in ST19) and it is confirmed that there is no board B at the extraction work position P2 (there is no board in ST29), the board location information 21 in the information processing device 3 is set to the current board extraction position. The status of the device 40 is updated (ST31). As a result, the information on the board B on the component mounting line 1 (production line) is appropriately reflected as the board location information 21.

Next, the extraction processing unit 32 activates the safety device of the board extraction device 40 (ST32). As a result, the opening/closing cover 13 of the board extraction device 40 is locked so that it cannot be opened or closed. Next, the substrate transport process by the transport processing section 31 is restarted (ST33), and the substrate extraction process (ST4) is completed.

Next, the substrate reloading process by the reloading support device will be described along the flowcharts of FIGS. 11 to 12 and with reference to FIGS. 13 to 15. In FIG. 11, first, the reloading processing unit 33 of the reloading support device causes the display device to display the board ID reading request screen 56 (FIG. 13(a)) of the reloaded board (ST41). When the "Cancel" button 56a is operated on the board ID reading request screen 56 for the re-loaded board, the board re-load process is canceled.

The "OK" button 56b is operated on the board ID reading request screen 56 for the re-loaded board, and the reader 4 acquires the board ID of the re-loaded board (obtains the board ID in ST42), and determines whether or not the re-load is possible. The unit 34 determines whether the re-input board can be re-introduced to the production line (component mounting line 1) based on the extracted board information 20 and the acquired board ID (ST43). When it is determined that the re-insertion board cannot be re-inserted (impossible in ST43), the re-insertion processing unit 33 causes the display device to display a re-insertion impossible warning screen 57 (FIG. 13(b)) (ST44). When the "close" button 57a is operated on the re-insertion impossible warning screen 57, the process returns to (ST41) and the board ID reading request screen 56 for the re-inserted board is displayed on the display device.

In FIG. 11, when it is determined that the re-insertion board can be re-inserted (possible in ST43), the re-insertion processing unit 33 displays the re-insertion location (device) selection request screen 58 (FIG. 14(a)) on the display device. (ST45). On the re-insertion location (apparatus) selection request screen 58, "conveyor #2" (second conveyor M5) and "inspection device #1" (print inspection device M4) are displayed as possible re-insertion locations. For example, a board B that is determined to be defective due to missing parts by the mounting inspection device M10 and removed from the production line, and which is determined to be mounted by the component mounting devices M6 to M8 without manually mounting the missing components, is placed on the production line. When returning, the production equipment (second conveyor M5, print inspection device M4) upstream from the component mounting devices M6 to M8 is set as a position where it can be reloaded.

When the reader 4 acquires the device ID of the production device to be re-injected (device ID acquired in ST46), the re-input processing unit 33 determines whether the re-input location specified by the acquired device ID is appropriate. is determined (ST47). If the production device for which the device ID has been acquired is inappropriate (inappropriate in ST47), the re-input processing unit 33 causes the display device to display the inappropriateness warning screen 59 (FIG. 14(b)) (ST48). The process returns to ST46) and waits until the device ID is obtained.

The inappropriateness warning screen 59 displays "conveyor #3" (third conveyor M9) and "inspection device #2" (mounted inspection device M10) as possible re-input positions. For example, when a board that is determined to be defective due to missing parts by the mounting inspection device M10 and removed from the production line is returned to the production line with the missing parts manually mounted, a mounting inspection is performed on that board B after reintroducing it. In this case, the mounting inspection device M10 or the production device (third conveyor M9) upstream of the mounting inspection device M10 is set as the re-loading possible position.

In FIGS. 11 and 12, when the production equipment whose equipment ID has been acquired is determined to be appropriate (appropriate in ST47), the re-input processing unit 33 notifies the selected re-input location (production equipment) to that effect. (ST49). For example, the selected production device is notified by displaying and blinking the selected production device on the display unit or by lighting an indicator light. Next, a re-input acceptance process is executed in the selected production equipment (ST50). Specifically, the board B is ejected from the re-loading location, the board B is prohibited from being carried into the re-loading location, the safety device is released, and the opening/closing cover is made openable and closable.

In FIG. 12, when the re-insertion acceptance process at the re-insertion location is completed, the re-insertion processing unit 33 causes the display device to display the board insertion permission notification screen 60 (FIG. 15(a)) (ST51). When the operator opens the reloading area cover, places the reloaded board on the conveyor (reloads it), and closes the reloaded cover (close cover in ST52), the reloaded board is placed in the reloaded area (equipment). It is determined whether or not there is one (ST53). If there is no reloading board at the reloading location (NO in ST53), the reloading processing section 33 displays the board reloading request screen 61 (FIG. 15(b)) on the display device (ST54), and then (ST52). Return to the re-insertion location and wait until the re-inserted board is reinserted.

If there is a re-input board at the re-input location (apparatus) (YES in ST53), the board location information 21 in the information processing device 3 is updated to the current status (ST55). Next, the re-injection processing section 33 activates the safety device at the re-injection location (ST56). As a result, the opening/closing cover at the reloading location is locked so that it cannot be opened or closed. Next, the operation of the re-inserting place (production equipment) is restarted (ST57), and the substrate re-inserting process is completed. In this way, it is possible to support the workpiece (board B) extracted from the middle of the production line (component mounting line 1) so that it can be properly reintroduced into the production line.

As explained above, the re-input support device of this embodiment uses the work identification information (board ID) of the work to be re-injected (board B) and the re-input location (production equipment ) is specified by the re-insertion location information, on the condition that the information acquisition means (reader 4) acquires the re-insertion location information (equipment ID) that can identify the and a re-input processing section 33 that makes it possible to re-inject the workpiece from the re-input location. As a result, it is possible to support workpieces taken out from the middle of the production line to be properly reintroduced to the production line.

In addition, in this embodiment, the second conveyor M5, the fourth conveyor M11, and the sixth conveyor M15 functioned as a re-feed support device, but the first conveyor M2, the printing device M3, the print inspection device M4, and the second conveyor M5, component mounting devices M6 to M8, and third conveyor M9 may all or partially have the same functions as the reloading processing section 33 and the reloading possibility determining section 34, and may function as a reloading support device. good.
