FIG. 5 is a schematic operation diagram showing an example of mounting work of the component mounting apparatus according to the first embodiment of the present invention, which shows a case where maintenance work on the first work lane 130 side is performed. .

When the user operates the component mounting apparatus 100 through the input / output console unit 197, the main controller 191 uses the input data or the vision system, and the sizes of the substrate P1 and the substrate P2 to be worked. And determine the type of work area on the side of the first work lane 130 and the work area on the side of the second work lane 150.

For example, if the size of the substrate P1 located in the first work lane 130 determined by the main controller 191 is much larger than the size of the substrate P2 located in the second work lane 150, the efficiency of the work may be reduced. In order to further secure a work area on the side of the first work lane 130 and to reduce the work area on the side of the second work lane 150. When the work area is determined by the main control unit 191 as described above, the main control unit 191 gives a command to the stopper control unit 199 to move the position of the stopper 195 to an appropriate position so as to fit the determined work area.

Subsequently, the first controller 140 applies power to the first power line 192 to drive the first head 110, the first transfer gantry 120, and the first work lane 130 to supply the substrate P1. We perform mounting work on). At the same time, the second controller 180 applies power to the second power line 193 to drive the second head 160, the second transfer gantry 170, and the second work lane 150. The mounting work on the substrate P2 is performed.

If a problem occurs in the work side of the first work lane 130 during the mounting operation as described above and the maintenance work is required, the first door 194a is opened when the user operates an operation device such as a button, and the operation device Sends an open signal to the first control unit 140.

According to the present embodiment, while the user operates the operation device such as a button to open the first door 194a and sends an open signal to the first control unit 140, the present invention is not limited thereto. That is, according to the present invention, when the user manually opens the first door 194a directly, the first door sensor 194a_1 may detect an open state and may send an open signal to the first controller 140.

When the first control unit 140 receives the opening signal, the first control unit 140 immediately stops the mounting work of the first work lane 130 and drives the first transfer gantry 120 to move the first head 110 to a designated position. Work space for maintenance work will be secured while protecting workers. Subsequently, the first control unit 140 cuts off the power of the first power line 192 to prevent a malfunction that may occur during operation.

However, as described above, in the component mounting apparatus 100 according to the first exemplary embodiment, since the first controller 140 and the second controller 180 operate independently of each other, the work on the second work lane 150 side is performed. Will continue as is. That is, the second controller 180 is not affected by the second head 160, the second transfer gantry 170, and the second work lane without any influence while the maintenance work on the first work lane 130 is in progress. 150 is driven to continue the mounting operation on the substrate P2. However, when the maintenance work on the side of the first work lane 130 is in progress and the body of the worker accidentally passes over to the second work lane 150 and is detected by the second motion detection sensor B2, the second control unit 180 immediately stops working on the second work lane 150 and emits a warning message such as an alarm and an alarm light.

On the other hand, in this case, the presence of the stopper 195 installed between the first transfer gantry 120 and the second transfer gantry 170, the second head 160 and the second transfer gantry 170 is By preventing the movement to the work area toward the first work lane 130, it is possible to further ensure the safety of the operator performing the maintenance work.

Subsequently, when the maintenance work on the side of the first work lane 130 ends and the user closes the first door 194a, the first door sensor 194a_1 detects a closed state and closes the first control unit 140. Will send a signal.

The first control unit 140 receives the closing signal and resumes the power supply of the first power line 192, and controls the first head 110, the first transfer gantry 120, and the first work lane 130. The driving is restarted, and the mounting work on the substrate P1 is performed. In this case, the second control unit 180 is not affected by the resumption of the mounting work toward the first work lane 130, and the second head 160, the second transfer gantry 170, and the second work lane are not affected. The drive of 150 is continued, and the mounting work to the board | substrate P2 is continued.

As described above, the driving of the component mounting apparatus 100 has been described when a problem occurs in the work side of the first work lane 130 during the mounting work and a maintenance work is required.

If a problem occurs on the work side of the second work lane 150 during the mounting operation as described above and the maintenance work is required, the second door 194b is opened when the user operates the operation device such as a button, and the operation device Sends an open signal to the second control unit 180.

According to the present exemplary embodiment, the user sends an opening signal to the second control unit 180 while opening the second door 194b by operating an operation device such as a button, but the present invention is not limited thereto. That is, according to the present invention, when the user manually opens the second door 194b directly, the second door sensor 194b_1 may detect the open state and send an open signal to the second controller 180.

When the second control unit 180 receives the opening signal, the second control unit 180 immediately stops the mounting work of the second work lane 150 and drives the second transfer gantry 170 to move the second head 160 to the designated position. Work space for maintenance work will be secured while protecting workers. Subsequently, the second control unit 180 cuts off the power of the second power line 193 to prevent a malfunction that may occur during operation.

However, as described above, in the component mounting apparatus 100 according to the first embodiment, since the first controller 140 and the second controller 180 operate independently of each other, the work on the side of the first work lane 130 is performed. Will continue as is. That is, the first control unit 140 is not influenced even during the maintenance work on the second work lane 150 without affecting the first head 110, the first transfer gantry 120, and the first work lane. 130 is driven to continue the mounting on the substrate P1. However, when the maintenance work on the second work lane 150 is in progress and the body of the worker accidentally goes over to the first work lane 130 and is detected by the first motion detection sensor B1, the first controller 140 immediately stops the work on the first work lane 130 and emits a warning message such as an alarm and an alarm light.

On the other hand, in this case, the presence of the stopper 195 installed between the first conveying gantry 120 and the second conveying gantry 170, the first head 110 and the first conveying gantry 120 is By preventing the movement to the work area of the second work lane 150, it is possible to further ensure the safety of the operator performing the maintenance work

Subsequently, when the maintenance work on the side of the second work lane 150 ends and the user closes the second door 194b, the second door sensor 194b_1 detects the closed state and closes the second control unit 180. Will send a signal.

The second controller 180 receives the closing signal and resumes the power supply of the second power line 193, and controls the second head 160, the second transfer gantry 170, and the second work lane 150. The driving is restarted, and the mounting work on the substrate P2 is performed. Even at this time, the first control unit 140 is not affected by the resumption of the mounting work on the second work lane 150, and the first head 110, the first transfer gantry 120, and the first one are not affected. The driving of the work lane 130 is maintained and the mounting work on the substrate P1 is continued.

As described above, according to the component mounting apparatus 100 according to the first embodiment, the first control unit 140 and the second control unit 180 operate independently of each other. That is, each of the first control unit 140 and the second control unit 180 independently manages operation programs for managing mounting work, stopping according to errors and emergency conditions of equipment, and responding to an emergency state. Related signal processing is also operated independently for each work lane. In addition, the first power line 192 and the second power line 193 are also provided separately from each other so as not to influence each other. Therefore, even if any one of the mounting work on the side of the first work lane 130 and the mounting work on the side of the second work lane 150 is interrupted, it does not affect the other. That is, since the other mounting work that is not interrupted may be maintained, the productivity and efficiency of the component mounting apparatus 100 may be maximized.

The distance holding device 299 is a device such that the one of the first X-direction beams 221 and the second X-direction beams 271 located on the open side is spaced apart from the stopper 295 by at least a predetermined distance. And a first distance holding cylinder 299a and a second distance holding cylinder 299b.

The distance maintaining device 299 operates under the control of the main controller 291, and is configured to receive power from the main power line 298.

The first distance holding cylinder 299a of the distance holding device 299 has a first rod 299a_1 and the second distance holding cylinder 299b has a second rod 299b_1, each rod 299a_1 and 299b_1 will move forward or backward in operation.

According to the second embodiment, the first and second distance holding cylinders 299a and 299b of the distance holding device 299 are respectively disposed in the first X-direction beam 221 and the second X-direction beam 271. Although installed, the present invention is not limited thereto. That is, the first and second distance holding cylinders 299a and 299b according to the present invention may be installed in the stopper 295 or the support frame portion 296. In this case, each of the first and second rods 299a_1 and 299b_1 of the first and second distance holding cylinders 299a and 299b respectively has a first X-direction beam 221 and a second X-direction beam 271 when moving forward. ) To limit the movement of the first X-direction beam 221 and the second X-direction beam 271.

The structure of the 1st, 2nd distance holding cylinders 299a and 299b should just be a structure which can advance and retract the rods 299a_1 and 299b_1, and there are no other structural restrictions. For example, the first and second distance holding cylinders 299a and 299b may have various structures such as an electronic linear motor, a hydraulic cylinder, and a pneumatic cylinder.

The stopper controller 300 controls the movement of the stopper 295 in response to a command of the main controller 291. To this end, the stopper controller 300 may be implemented in the form of a controller circuit, an IC chip, and a program capable of controlling the internal motor of the stopper 295.

Hereinafter, the operation of the component mounting apparatus 200 according to the second embodiment will be described.

When the user operates the component mounting apparatus 200 through the input / output console unit 297, the main control unit 291 uses the input data or the vision system, and the sizes of the substrate P1 and the substrate P2 to be worked. And the kind of work area of the first work lane 230 and the work area of the second work lane 250.

For example, if the size of the substrate P1 located in the first work lane 230 determined by the main control unit 291 is much larger than the size of the substrate P2 located in the second work lane 250, the work efficiency may be reduced. In order to further secure the work area toward the first work lane 230 and to reduce the work area toward the second work lane 250. When the work area is determined by the main control unit 291 as described above, the main control unit 291 gives a command to the stopper control unit 300 to move the position of the stopper 295 to an appropriate position so as to fit the determined work area.

The first controller 240 applies power to the first power line 292 to drive the first head 210, the first transfer gantry 220, and the first work lane 230 to the substrate P1. Perform the mounting work. At the same time, the second controller 280 applies power to the second power line 293 to drive the second head 260, the second transfer gantry 270, and the second work lane 250. The mounting work on the substrate P2 is performed.

On the other hand, there is a case where a problem occurs on the work side of the second work lane 250 during the mounting work, and maintenance work is necessary. Hereinafter, referring to FIG. 10, the component mounting apparatus 200 of such a case will be described. Let's look at driving.

If a problem occurs in the work side of the second work lane 250 during the mounting operation as described above and the maintenance work is required, the second door sensor 294b_1 is in an open state when the user opens the second door 294b. Detects and sends an open signal to the main controller 291.

The main controller 291 receives the opening signal and transmits the open signal to the second controller 280. Upon receiving the open signal, the second control unit 280 immediately stops the mounting work of the second work lane 250 and drives the second transfer gantry 270 to move and maintain the second head 260 to a designated position. You will have a working space for maintenance work and protect your workers.

Subsequently, the second controller 280 cuts off the power of the second power line 293 to prevent a malfunction that may occur during operation. When the power is cut off, the second head 260, the second transfer gantry 270, and the second work lane 250 are in a servo off state, thereby stopping in a no load state.

In addition, when receiving the open signal, the main controller 291 advances the second rod 299b_1 by operating the second distance maintaining cylinder 299b. The advanced second rod 299b_1 is supported in contact with the stopper 295 so that the distance between the stopper 295 and the second X-direction beam 271 maintains at least a predetermined distance L1. The predetermined distance L1 may be determined such that the second head 260 does not hit the first head 210.

That is, the area A1 shown in FIG. 10 is a danger area in which the first head 210 in operation is likely to move, and the stopper 295 and the second X-direction beam 271 are driven by the second distance holding cylinder 299b. Since the distance between is maintained at least a predetermined distance L1, the second X-direction beam 271 and the second head 260 is kept sufficiently separated from the area A1. In this case, since the second door 294b is opened and the operator manually moves the second X-direction beam 271 for the work, the second door 294b is not moved in the Y2 direction but can move only in the Y1 direction. The risk that the 2 X-direction beam 271 and the second head 260 collide with the first head 210 is prevented.

Meanwhile, as described above, in the component mounting apparatus 200 according to the second embodiment, since the first control unit 240 and the second control unit 280 operate independently of each other, the work on the side of the first work lane 230 is performed. Will continue as is. That is, the first control unit 240 is not affected even while the maintenance work on the second work lane 250 is in progress without affecting the first head 210, the first transfer gantry 220, and the first work lane. The 230 is driven to continue the mounting operation on the substrate P1.

In this case, since the first head 210 and the first transfer gantry 220 are prevented from being moved to the work area toward the second work lane 250 by the stopper 295, damage of the device due to the collision is prevented. Prevents and further ensures the safety of operators performing maintenance work.

Subsequently, when the maintenance work on the side of the second work lane 250 is terminated and the user closes the second door 294b, the second door sensor 294b_1 detects the closed state and sends a closing signal to the main controller 291. Will be sent.

The main controller 291 retreats the second rod 299b_1 by operating the second distance holding cylinder 299b when the closing signal is received. In addition, the main control unit 291 receives the closing signal and transmits the closing signal to the second control unit 280. When the second control unit 280 receives the closing signal, the power supply of the second power line 293 resumes. The driving of the second head 260, the second transfer gantry 270, and the second work lane 250 is resumed to perform the mounting work on the substrate P2. In this case, the first control unit 240 is not affected by the resumption of the mounting work on the second work lane 250, and the first head 210, the first transfer gantry 220, and the first work lane are not affected. The 230 is driven to continue the mounting operation on the substrate P1.

As described above, the driving of the component mounting apparatus 200 has been described when a problem occurs on the work side of the second work lane 250 during the mounting work and a maintenance work is required.

Hereinafter, referring to FIG. 11, the driving of the component mounting apparatus 200 when a problem occurs in the work side of the first work lane 230 during the mounting work and requires maintenance work will be described briefly. do.

If a problem occurs in the work side of the first work lane 230 during the mounting operation and requires maintenance work, when the user opens the first door 294a, the first door sensor 294a_1 detects an open state. The open signal is sent to the main controller 291.

The main controller 291 sends the opening signal to the first controller 240. The first control unit 240 receiving the open signal immediately stops the mounting work of the first work lane 230, drives the first transfer gantry 220, and moves the first head 210 to a designated position. You will have a working space for maintenance work and protect your workers.

Subsequently, the first control unit 240 cuts off the power of the first power line 292 to prevent a malfunction that may occur during operation. When the power is cut off, the first head 210, the first transfer gantry 220, and the first work lane 230 are in a servo off state and stop at a no load state.

In addition, the main controller 291 advances the first rod 299a_1 by operating the first distance maintaining cylinder 299a when receiving the opening signal. The advanced first rod 299a_1 is supported in contact with the stopper 295 so that the distance between the stopper 295 and the first X-direction beam 221 maintains at least a predetermined distance L2. The predetermined distance L2 may be determined such that the first head 210 does not hit the second head 260.

That is, the area A2 shown in FIG. 11 is a danger area in which the second head 260 in operation is likely to move, and the stopper 295 and the first X-direction beam 221 are driven by the first distance holding cylinder 299a. ) Is maintained at least a predetermined distance L2, so that the first X-direction beam 221 and the first head 210 is sufficiently spaced apart from the area A2. In this case, since the first door 294a is opened and the operator manually moves the first X-direction beam 221 for work, the first door 294a is not moved in the Y1 direction but can move only in the Y2 direction. The risk that the 1 X-direction beam 221 and the first head 210 collide with the second head 260 is prevented.

Meanwhile, as described above, in the component mounting apparatus 200 according to the second exemplary embodiment, since the first control unit 240 and the second control unit 280 operate independently of each other, the work on the second work lane 250 side may be performed. Will continue as is. That is, the second controller 280 is not affected by the second head 260, the second transfer gantry 270, and the second work lane while the maintenance work on the first work lane 230 is in progress. 250 is driven to continue the mounting on the substrate P2.

In this case, the second head 260 and the second transfer gantry 270 are prevented from being moved to the work area toward the first work lane 230 by the stopper 295, thereby causing damage to the device due to the collision. And further ensure the safety of operators performing maintenance work.

Subsequently, when the maintenance work on the side of the first work lane 230 ends and the user closes the first door 294a, the first door sensor 294a_1 detects a closed state and then closes the signal to the main controller 291. Will be sent.

The main controller 291 retreats the first rod 299a_1 by operating the first distance maintaining cylinder 299a when receiving the closing signal. In addition, the main control unit 291 transmits the closing signal to the first control unit 240. When the first control unit 240 receives the closing signal, the main control unit 291 resumes the power supply of the first power line 292, and The driving of the first head 210, the first transfer gantry 220, and the first work lane 230 is resumed to perform the mounting work on the substrate P1. In this case, the second control unit 280 is not affected by the resumption of the mounting work on the first work lane 230, and the second head 260, the second transfer gantry 270, and the second work lane are not affected. 250 is driven to continue the mounting on the substrate P2.

As described above, according to the component mounting apparatus 200 according to the second embodiment, the first control unit 240 and the second control unit 280 operate independently of each other. That is, each of the first control unit 240 and the second control unit 280 independently operates an operation program for managing the mounting operation management, and the related signal processing is independently operated for each work lane. The first power supply line 292 and the second power supply line 293 are also provided separately from each other so as not to affect each other. Therefore, even if any one of the mounting work on the first work lane 230 and the mounting work on the second work lane 250 is interrupted, the other work is not affected. In other words, since the other mounting work that is not interrupted may be maintained, the productivity and efficiency of the component mounting apparatus 200 may be maximized.

In addition, according to the component mounting apparatus 200 according to the second embodiment, the distance holding device 299 is included. The distance holding device 299 maintains a predetermined distance so that the transfer gantry on the open door side and the head do not interfere with the work area of the head on the non-open door side, thereby preventing damage to the internal device due to the collision. And further ensure the safety of workers performing maintenance work.
