Description

The present specification relates to a board-to-board working machine provided with a board transfer device for loading and unloading a substrate.

A technique for mass-producing substrate products by performing substrate-to-board work on a substrate on which a circuit pattern is formed has become widespread. As a typical example of a board-to-board work machine that performs board-to-board work, there is a component mounting machine that carries out component mounting work. In general, a component mounting machine includes a board transport device for loading and unloading a substrate along a transport path, and a component mounting tool for collecting and mounting parts. Here, the substrate may be inserted into the transport path by the operator due to sampling inspection or other circumstances. Further, for the purpose of measuring the accuracy of the mounting position of the component, a jig plate having a shape similar to the substrate may be inserted into the transport path by the operator. Patent Document 1 discloses a technical example regarding the posture of a substrate in a transport path.

The component mounting machine of Patent Document 1 recognizes the posture of the substrate after stopping the transport when a substrate transport abnormality occurs during the transport of the substrate by the conveyor, and based on the recognized posture of the substrate, a pair of parts mounting machines. After correcting the posture of the substrate by running one of the transport belts in the opposite direction, the transport is restarted. According to this, it is said that the productivity of the substrate can be improved by surely eliminating the transfer abnormality of the substrate.

JP-A-2017-157651

By the way, there is a possibility that a human error may occur when an object to be transported corresponding to a substrate or a jig plate is inserted into a transport path by an operator instead of a substrate transport device. If the work on the substrate and the accuracy measurement work are carried out while the posture of the transported object is abnormal, the accurate work may not be performed or the component mounting tool may accidentally collide with the transported object.

On the other hand, the technique of Patent Document 1 can automatically correct the abnormality by the operation of the substrate transport device when a slight abnormality occurs in which the substrate is slanted with respect to the transport path. However, in many cases, the abnormal posture of the transported body due to human error cannot be eliminated by the operation of the substrate transport device. Therefore, it is necessary to detect an abnormality in the posture of the transported body, suspend the execution of the work, correct the posture of the transported body, and then perform the work. This problem is not limited to the component mounting machine, but is common to various board-to-board working machines equipped with a board transfer device.

In the present specification, it is an object to be solved to provide an anti-board working machine capable of discriminating an abnormality in the posture of a transported object inserted into a transport path by an operator.

In the present specification, a substrate transport device that carries in and out a substrate along a transport path to a work execution position, a work execution device that performs a predetermined work on the substrate carried in the work execution position, and the substrate. Alternatively, when an object to be transported, which is a jig plate having a shape similar to the substrate, is inserted into the transfer path by an operator, a moving portion that moves the object to be transported by the operation of the substrate transfer device and the moved subject. A pair including a detection unit that detects a transport body and a control unit that regulates the movement of the transport body with the operation of the substrate transport device when the posture of the transport body with respect to the transport path is abnormal. Disclose the board working machine.

According to the anti-board working machine disclosed in the present specification, the transferred body is inserted by the operator moving the transported object inserted into the transport path by the substrate transport device and detecting it by the detection unit. You can check it. Here, when the posture of the inserted body to be transported is abnormal, the regulating unit regulates the movement of the body to be transported, and therefore the detection unit does not detect the body to be transported, so that the posture of the body to be transported is abnormal. Is determined.

1. 1. Overall configuration of the component mounting machine 1 (board working machine) As the board working machine of the first embodiment, the component mounting machine 1 shown in FIG. 1 will be described as an example. The component mounting machine 1 performs mounting work for mounting the component on the substrate K. The direction from the left side to the right side of the paper surface in FIG. 1 is the X-axis direction for transporting the substrate K, and the direction from the lower side (front side) of the paper surface to the upper side (rear side) of the paper surface is the Y-axis direction. The component mounting machine 1 is configured by assembling a board transfer device 2, a plurality of feeders 3, a component transfer device 4, a component camera 5, a positioning device 6, a control device 7, and the like on a base 10.

The board transfer device 2 carries the board K to the work execution position along the transfer path 2A (see FIG. 3) and carries it out. The positioning device 6 positions the substrate K carried into the work execution position. In FIG. 1, the substrate K at the work execution position is drawn. The configurations of the substrate transfer device 2 and the positioning device 6 will be described in detail later.

The plurality of feeders 3 are detachably mounted in a plurality of groove-shaped slots provided in the pallet member 11 on the base 10. The feeder 3 is loaded with a reel 39 on the front side of the main body 31. A predetermined supply position 32 for supplying parts is set in the upper part near the rear side of the main body 31. A carrier tape containing parts is wound around the reel 39 in a large number of cavities. The feeder 3 intermittently feeds the carrier tape by the tape feeding mechanism (not shown), and sets the parts at the supply position 32. As a result, the feeder 3 performs the component supply operation.

The component transfer device 4 is arranged above the substrate transfer device 2 and the feeder 3. The component transfer device 4 collects components from the feeder 3 and mounts them on the substrate K. The component transfer device 4 includes a head drive mechanism 40, a moving table 44, a mounting head 45, a suction nozzle 46, a mark camera 47, and the like. The head drive mechanism 40 includes a pair of Y-axis rails 41 and 42, a Y-axis slider 43, and a drive motor (not shown). The Y-axis rails 41 and 42 extend in the Y-axis direction and are separated from each other and arranged in parallel. The Y-axis slider 43, which is long in the X-axis direction, is mounted across both Y-axis rails 41 and 42 and moves in the Y-axis direction. The moving table 44 is mounted on the Y-axis slider 43 and moves in the X-axis direction. The head drive mechanism 40 drives the Y-axis slider 43 in the Y-axis direction and drives the moving table 44 on the Y-axis slider 43 in the X-axis direction.

The moving table 44 holds the mounting head 45 and the mark camera 47. The mounting head 45 holds one or a plurality of suction nozzles 46 on the lower side, and is driven by the head drive mechanism 40 to move in two horizontal directions. The suction nozzle 46 is driven by the elevating drive unit (not shown) to move up and down. The suction nozzle 46 descends from above the supply position 32 and performs a suction operation of sucking and collecting parts by supplying a negative pressure. Further, the suction nozzle 46 is driven above the substrate K and performs a mounting operation of mounting the components by supplying a positive pressure. There are a plurality of types of the mounting head 45 and the suction nozzle 46, which are automatically or manually replaced. The mark camera 47 captures a position mark attached to the positioned substrate K to detect an accurate work execution position of the substrate K.

The component camera 5 is provided upward on the upper surface of the base 10 between the substrate transfer device 2 and the feeder 3. The component camera 5 takes an image of the component sucked by the suction nozzle 46 while the moving table 44 is moving from the feeder 3 to the substrate K. The image processing unit of the component camera 5 performs image processing on the acquired image data to determine the presence / absence and correctness of the component, and further acquires the suction posture of the component. The result of the image processing is reflected in the mounting operation of the suction nozzle 46. The feeder 3, the component transfer device 4, and the component camera 5 correspond to work execution devices that perform component mounting work.

The control device 7 is assembled to the base 10, and the arrangement position thereof is not particularly limited. The control device 7 is composed of a computer device having a CPU and operating by software. The control device 7 may be configured by having a plurality of CPUs distributed in the machine. The control device 7 controls the component mounting work according to the job data stored in advance. Job data differs depending on the type of board product to be produced.

2. 2. Configuration of Substrate Transfer Device 2 and Positioning Device 6 Next, the configurations of the substrate transfer device 2 and the positioning device 6 will be described in detail. As shown in FIGS. 2 and 3, the substrate transfer device 2 includes a pair of side plates 21, 22, a pair of rail guides 23, 24, a pair of transfer belts 25, 26, and two substrate passage sensors 27, 28. And so on. The pair of side plates 21 and 22 are erected in parallel on the base 10 and extend in the X-axis direction, respectively. The pair of rail guides 23 and 24 have a plate shape and are horizontally provided on the upper portions of the side plates 21 and 22. The pair of rail guides 23, 24 extend in the X-axis direction and project inward facing each other.

The pair of transport belts 25 and 26 are provided between the rail guides 23 and 24 and the base 10, respectively. A transport path 2A for transporting the substrate K is formed between the transport belts 25 and 26 and the rail guides 23 and 24. The pair of transport belts 25 and 26 rotate the substrate K in the X-axis direction along the transport path 2A by rotating the side edges KS and KT of the rectangular substrate K, respectively. The pair of transport belts 25 and 26 can transport the substrate K in the reverse direction by rotating in the opposite direction.

The work execution position is set at the center of the transport path 2A in the Y-axis direction. A first substrate passage sensor 27 is provided in the vicinity of the carry-in end 2B of the transport path 2A. A second substrate passage sensor 28 is provided in the vicinity of the carry-out end 2C of the transport path 2A. As the two substrate passage sensors 27 and 28, a light-shielding detection sensor in which a light-emitting unit that emits the detection light L and a light-receiving unit that receives the detection light L can be exemplified. Since the detection light L is blocked by the substrate K, the shading detection sensor detects the arrival and passage of the front edge KF and the trailing edge KR of the substrate K.

On the other hand, the rail guide 23 can be slidably moved in the arrow M direction (Y-axis direction) as shown by the broken line in FIG. When one rail guide 23 slides away from the other rail guide 24, the transport path 2A is opened. Therefore, the operator can directly insert the substrate K into the transport path 2A without passing through the carry-in end 2B and the carry-out end 2C. Further, the operator can take out the substrate K directly from the transport path 2A. Such an operator operation occurs, for example, when performing a sampling inspection of the substrate K.

Further, there is a jig plate Z (see FIG. 5) as a member that is directly inserted into the transport path 2A. The jig plate Z has a rectangular shape similar to that of the substrate K. The jig plate Z is used for, but is not limited to, the accuracy measurement work of the mounting position of the component. In the following description, "conveyed body" will be used as necessary as a name including the substrate K and the jig plate Z.

The object to be transported inserted in the transport path 2A is moved by the operation of the substrate transport device 2. Then, at least one of the two substrate passage sensors 27 and 28 is also used as a detection unit for detecting the moved object to be transported. In the first embodiment, the substrate passage sensor 27 in the vicinity of the carry-in end 2B is also used as the detection unit.

The positioning device 6 is arranged below the work execution position. The positioning device 6 has a device main body 61, a plurality of clamp rods 62, and a rod rise amount detecting unit 63 (see FIG. 4). The plurality of clamp rods 62 push up the substrate K and clamp between the rail guides 23 and 24 by ascending in synchronization with the apparatus main body 61. As a result, the substrate K is positioned so as not to move from the work execution position. The ascending amount of the clamp rod 62 is detected by the rod ascending amount detecting unit 63.

3. 3. Configuration of control of component mounting machine 1 Next, the configuration of control of component mounting machine 1 will be described in detail. As shown in FIG. 4, the control device 7 controls the transfer belts 25 and 26 of the substrate transfer device 2 and receives detection signals from the substrate pass sensors 27 and 28. Further, the control device 7 controls a plurality of feeders 3, a component transfer device 4, and a component camera 5. Further, the control device 7 controls the clamp rod 62 of the positioning device 6 and receives a detection signal from the rod ascending amount detecting unit 63.

Further, the control device 7 includes a moving unit 71, a confirmation unit 72, and a determination unit 73 as functional units for detecting the presence / absence of the transported body and the posture. These functional units execute the control of the control device 7 described above and refer to the detection signal described above. The confirmation unit 72 and the determination unit 73 may be omitted (details will be described later).

The moving unit 71 operates when the transported body is inserted into the transport path 2A by the operator. The insertion of the transported body is input to the control device 7 by the operator. The moving unit 71 moves the transported object by the operation of the substrate transport device 2. Specifically, the moving unit 71 rotates the transport belts 25 and 26 in the opposite direction, and moves the transported object in the reverse direction of the transport toward the substrate passage sensor 27 that is also used as the detection unit.

When the substrate passage sensor 27 detects the trailing edge of the transported object, the moving unit 71 immediately stops the transport belts 25 and 26. As a result, the position of the transported body on the transport path 2A is clarified. After that, the substrate transport device 2 transports the object to be transported to the work execution position. Subsequently, when the transported body is the substrate K, the component mounting work is performed, and when the transported body is the jig plate Z, the accuracy measurement work is performed.

Here, the continuation of the rotation of the transport belts 25 and 26 in the opposite directions is limited to a predetermined time. When the substrate passage sensor 27 does not detect the trailing edge of the transported body even after the lapse of a predetermined time, the moving unit 71 stops the transport belts 25 and 26. At this time, the control device 7 can determine that some abnormality has occurred. Two cases can be considered as specific examples of the abnormality. That is, there are cases where the transported body having an abnormal posture does not actually move due to the action of the regulating units 81 and 82 (details will be described later), and cases where the transported body is not originally inserted.

When the substrate passage sensor 27 does not detect the transported object, the confirmation unit 72 confirms the presence or absence of the transported object by the operation of the positioning device 6. Specifically, the confirmation unit 72 drives the clamp rod 62 ascending, and confirms the presence or absence of the transported object based on the detection signal of the rod ascending amount detecting unit 63.

The determination unit 73 makes a determination based on the detection signal of the substrate passage sensor 27 and the confirmation result of the confirmation unit 72. Specifically, the determination unit 73 determines that the posture of the transported body is normal when the substrate passing sensor 27 detects the transported body. Further, the determination unit 73 determines that the posture of the transported body is abnormal when the substrate passage sensor 27 does not detect the transported body and the confirmation unit 72 confirms the presence of the transported body. Further, when the substrate passage sensor 27 does not detect the transported body and the confirmation unit 72 confirms that there is no transported body, the determination unit 73 determines that the transported body is not originally inserted.

4. Forms of Regulatory Units 81 and 82 and Their Actions Next, the forms and actions of the regulators 81 and 82 provided on the jig plate Z will be described. As shown in FIG. 5, two regulation portions 81 and 82 are provided on the back surface of the jig plate Z. More specifically, the regulating portions 81 and 82 are arranged over the substantially overall length of both side edges ZS and ZT of the jig plate Z, respectively. The regulating portions 81 and 82 are friction materials that regulate the movement of the jig plate Z by generating a large frictional force with other members. As the friction material, a rubber sheet can be exemplified, and the friction material is not limited thereto.

When the operator correctly inserts the jig plate Z into the transport path 2A, the normal state shown in FIG. 6 is obtained. As shown, when the posture of the jig plate Z is normal, both side edges ZS and ZT of the jig plate Z are correctly positioned below the rail guides 23 and 24. Therefore, the two regulation portions 81 and 82 of the jig plate Z are placed on the transport belts 25 and 26, respectively. Therefore, the jig plate Z moves when the moving unit 71 operates the substrate transport device 2. As a result, the substrate passage sensor 27 detects the jig plate Z, and the determination unit 73 determines that the posture of the jig plate Z is normal.

On the other hand, if a human error occurs when the operator inserts the jig plate Z into the transport path 2A, the abnormal state shown in FIG. 7 occurs. As shown, when the posture of the jig plate Z is abnormal, one side edge ZS of the jig plate Z is correctly positioned under the rail guide 23, but the other side edge ZT is a rail. It is erroneously positioned above the guide 24. Therefore, the other regulating portion 82 of the jig plate Z and the upper surface of the rail guide 24 come into contact with each other, and a large frictional force is generated. This frictional force regulates the movement of the jig plate Z. Therefore, even if the moving unit 71 operates the substrate transfer device 2, the jig plate Z does not move. As a result, the substrate passage sensor 27 does not detect the jig plate Z, and the confirmation unit 72 starts operation.

A second abnormal state may occur in which one side edge ZS of the jig plate Z is erroneously positioned above the rail guide 23 and the other side edge ZT is correctly positioned below the rail guide 24. .. Further, it cannot be said that there is no third abnormal state in which both side edges ZS and ZT of the jig plate Z are erroneously positioned above the rail guides 23 and 24. Even in the second and third abnormal states, the jig plate Z does not move, and the confirmation unit 72 starts operation.

If the operator does not insert the jig plate Z and does not consider the input error of accidentally inputting "the jig plate Z is inserted" to the control device 7, the confirmation unit 72 and the determination unit 73 become unnecessary. .. In this case, since the substrate passage sensor 27 does not detect the jig plate Z, the control device 7 can immediately determine the posture abnormality of the jig plate Z.

When considering the above-mentioned input error, the control device 7 cannot determine whether the jig plate Z has an abnormal posture or whether the jig plate Z is not originally inserted. In this case, the confirmation unit 72 and the determination unit 73 operate to enable the determination.

As shown in FIG. 8, the confirmation unit 72 drives the clamp rod 62 of the positioning device 6 ascending. Then, the clamp rod 62 pushes up the jig plate Z that has not moved from the inserted position, and clamps one side edge ZS and the regulation portion 81 between the rail guide 23 and the jig plate Z. At this time, the rod ascending amount detecting unit 63 detects the separation dimension D between the tip of the clamp rod 62 and the rail guides 23 and 24. As a result, the confirmation unit 72 can confirm the presence or absence of the jig plate Z based on the existence of the separation dimension D. The determination unit 73 determines that the posture of the jig plate Z is abnormal.

Next, it is assumed that the operator mistakenly inputs "the jig plate Z has been inserted" to the control device 7 without inserting the jig plate Z. In this case, even if the moving unit 71 operates the substrate transfer device 2, the substrate passage sensor 27 cannot detect the jig plate Z, and the confirmation unit 72 starts the operation. Then, as shown in FIG. 9, the clamp rod 62 rises and comes into contact with the rail guides 23 and 24. At this time, the rod rise amount detecting unit 63 detects that the separation dimension D does not exist. As a result, the confirmation unit 72 can confirm the absence of the jig plate Z based on the absence of the separation dimension D. The determination unit 73 determines that the jig plate Z is not originally inserted.

When the posture of the jig plate Z is abnormal or the jig plate Z is not originally inserted, the control device 7 notifies the operator of an alarm indicating that an abnormality has occurred, and measures the accuracy thereafter. Suspend the work. The operator corrects the jig plate Z of the transport path 2A to the correct posture, or correctly inserts the jig plate Z into the transport path 2A, and inputs that fact to the control device 7. Then, the moving unit 71 and the determination unit 73 operate again, and it can be determined that the posture of the jig plate Z is normal this time.

If the jig plate Z is not provided with the regulating portions 81 and 82, the jig plate Z moves by being driven from only one of the transport belts 25 even if the posture of the jig plate Z is abnormal. Therefore, the accuracy measurement work is started while the posture of the jig plate Z remains abnormal. Then, the accuracy measurement work is not carried out correctly. In addition, there is a possibility that the moving suction nozzle 46, the sucked parts, the mark camera 47, and the like may collide with the portion of the jig plate Z having an abnormal posture protruding upward from the transport path 2A.

On the other hand, in the first embodiment, the posture abnormality of the jig plate Z can be surely eliminated before the accuracy measurement work is started. As a result, the accuracy measurement work using the jig plate Z is correctly performed. Furthermore, the risk of collision described above is reliably avoided.

Further, since the regulating portions 81 and 82 are provided on the jig plate Z, a large frictional force is generated between the regulating portions 81 and 82 and the transport belts 25 and 26. Therefore, the jig plate Z does not slip on the transport belts 25 and 26, and high position accuracy is maintained. In addition, the clamp rod 62 of the positioning device 6 positions the jig plate Z via the regulating portions 81 and 82 made of rubber sheets. Therefore, even if the jig plate Z is used repeatedly, aging wear is suppressed.

According to the component mounting machine 1 of the first embodiment, the jig plate Z is moved by the substrate transfer device 2 and detected by the substrate passage sensor 27 by the operator to move the jig plate Z inserted into the transfer path 2A. You can confirm that it has been inserted. Here, when the posture of the inserted jig plate Z is abnormal, the regulating portions 81 and 82 restrict the movement of the jig plate Z, so that the substrate passage sensor 27 does not detect the jig plate Z. , The abnormality of the posture of the jig plate Z is determined.

5. Embodiments of the regulating portions 83 and 84 of the second embodiment and their actions Next, in the second embodiment, both the substrate K and the jig plate Z can be used as the objects to be transported. In the second embodiment, the overall configuration of the component mounting machine 1 is the same as that in the first embodiment, and the embodiments of the regulation units 83 and 84 are different from those in the first embodiment. As shown in FIG. 10, the regulating portions 83 and 84 of the second embodiment are provided on the upper surfaces of the pair of rail guides 23 and 24, respectively. More specifically, the regulating portions 83 and 84 are provided on the inner surfaces of the rail guides 23 and 24 facing each other, and extend from above the positioning device 6 to the vicinity of the substrate passage sensor 27. The regulating units 83 and 84 are friction materials that regulate the movement of the transported object by generating a large frictional force with the transported object. The material of the friction material may be the same rubber sheet as in the first embodiment, or may be a different material.

When the postures of the substrate K and the jig plate Z are abnormal, the side edge KT and the side edge ZT are erroneously positioned above the regulation portion 84 of the rail guide 24, for example, as shown in FIG. Therefore, a large frictional force is generated between the back surface of the substrate K or the jig plate Z and the regulating portion 84. This frictional force regulates the movement of the substrate K and the jig plate Z. Therefore, even if the moving unit 71 operates the substrate transport device 2, the substrate K and the jig plate Z do not move. Hereinafter, the same actions and effects as those of the first embodiment occur.

6. Embodiments of the regulating portions 85 and 86 of the third embodiment and their actions Next, in the third embodiment, both the substrate K and the jig plate Z can be used as the objects to be transported. In the third embodiment, the overall configuration of the component mounting machine 1 is the same as that of the first embodiment, and the embodiments of the regulation units 85 and 86 are different from those of the first and second embodiments. As shown in FIG. 12, the regulating portions 85 and 86 of the third embodiment are provided on the upper surfaces of the pair of rail guides 23 and 24, respectively. More specifically, the regulating portions 85 and 86 are arranged on the inner surfaces of the rail guides 23 and 24 facing each other, which are slightly closer to the work execution position than the substrate passing sensor 27. In addition, the regulating portions 85 and 86 are formed in convex portions protruding upward from the upper surfaces of the rail guides 23 and 24.

The convex portion-shaped regulating portions 85 and 86 are provided to block the moving path of the substrate K and the jig plate Z. The convex portion-shaped restricting portions 85 and 86 preferably have the above-mentioned arrangement locations and preferably have the minimum height capable of reliably blocking the movement path. As a result, it is possible to avoid the possibility that the moving suction nozzle 46, the sucked parts, the mark camera 47, and the like interfere with the convex portion-shaped regulating portions 85 and 86.

When the posture of the substrate K or the jig plate Z is abnormal, the side edge KT or the side edge ZT is erroneously positioned on the upper side of the rail guide 24, for example, as shown in FIG. Therefore, when the moving unit 71 operates the substrate transport device 2, the substrate K and the jig plate Z move until they come into contact with the regulating portions 85 and 86, but do not reach the substrate passing sensor 27. Therefore, the substrate passage sensor 27 does not detect the substrate K or the jig plate Z. Hereinafter, the same actions and effects as those of the first embodiment occur.

7. Application and Modification of the Embodiment Although the substrate passage sensor 27 on the carry-in side is also used as the detection unit, the substrate passage sensor 28 on the carry-out side can also be used as the detection unit. In this case, the positions of the regulation units 83 to 86 described in the second and third embodiments are changed to the side of the substrate passage sensor 28. Further, the first to third embodiments can be applied to a board-to-board working machine other than the component mounting machine 1, for example, a solder printing machine or a board inspection machine provided with a board transfer device 2. The first to third embodiments can be applied and modified in various ways.
