Disclosure of Invention
Technical problem to be solved by the invention
The inspection object may be inspected in a state having a flexible wiring board. However, the inspection apparatus of patent document 1 is an inspection apparatus that automatically inspects an object to be inspected that does not have a flexible wiring board, but cannot inspect an object to be inspected that has a flexible wiring board. Therefore, conventionally, when inspecting an inspection object having a flexible wiring board, the inspection object is placed on a placement unit, and then a power supply unit of the flexible wiring board and a power supply unit for inspection are electrically connected by a manual work of an operator. As a result, the inspection apparatus cannot automatically inspect the inspection object, and therefore, there is a problem in that the inspection time of the inspection object becomes long.
The present invention has been made to solve the above-described problems, and an object to be inspected having a flexible wiring board can be automatically inspected.
Technical scheme for solving technical problems
In order to solve the above-described problems, the present invention provides an inspection apparatus for inspecting an object to be inspected, the object to be inspected including a substrate and a flexible wiring board, one end of the flexible wiring board being connected to the substrate, and a power-supplied portion being provided on one surface side of the other end of the flexible wiring board, the inspection apparatus comprising: a mounting portion on which the substrate is mounted such that the one surface faces one side in a horizontal direction when the flexible wiring board is hung down; a suction head for posture correction that rotates the suspended flexible wiring board from below so as to overlap the board, and sucks the flexible wiring board, and then rotates the flexible wiring board in the opposite direction so as to set the flexible wiring board in a state suspended in the vertical direction; an adsorption head that adsorbs a rear surface portion of the power-supplied portion in the other surface of the flexible wiring board hanging down in the vertical direction; an inspection power supply unit facing the power supply unit in a state where the flexible wiring board is adsorbed to the adsorption head on one side in a horizontal direction; and a transport mechanism that moves the suction head and the mounting portion to one side in the horizontal direction so as to electrically connect the power receiving portion and the inspection power feeding portion, while the suction of the flexible wiring board by the suction head for posture correction is stopped.
According to the present invention, even in the case of a flexible wiring board in a free posture, the posture-correcting suction head can be set in a state of hanging down in the vertical direction. The suction head can suck the back surface part of the supplied power part in the other surface of the flexible wiring substrate hanging down along the vertical direction. The transport mechanism can move the suction head and the mounting portion to one side in the horizontal direction to electrically connect the power supply unit to the inspection power supply unit. As a result, the inspection apparatus of the present invention can perform automation of inspection even for an inspection object having a flexible wiring board.
In the present invention, it is preferable that the inspection device further comprises a monitor device for detecting a position of the power-supplied portion, and when the power-supplied portion and the inspection power-supplied portion are electrically connected, a relative position between the power-supplied portion and the inspection power-supplied portion is adjusted based on a result of monitoring by the monitor device. In the present invention, it is preferable that the power receiving unit includes a connector. Therefore, since the position of the inspection power supply unit can be adjusted with respect to the power supply unit, the power supply unit and the inspection power supply unit can be reliably connected.
In the present invention, it is preferable that the suction head for posture correction includes a first type of inspection object and a second type of inspection object, the suction head for posture correction includes a first surface of the first type of inspection object facing the substrate side when the flexible wiring board is overlapped with the substrate from the lower side in the vertical direction, the suction head for posture correction includes a second surface of the second type of inspection object facing the opposite side of the substrate, the flexible wiring board is set to a state of hanging down in the vertical direction by the suction head for posture correction in the case of the first type of inspection object, and the flexible wiring board is set to a state of hanging down in the vertical direction by the suction head for posture correction in the case of the second type of inspection object. Therefore, the flexible wiring board can be set to a state of hanging down in the vertical direction by the first posture correcting suction head and the second posture correcting suction head, regardless of which direction the one surface of the flexible wiring board is facing, that is, either the first type of the inspection object or the second type of the inspection object.
In the present invention, it is preferable that the mounting portion includes an opening for drawing the flexible wiring board downward, and the flexible wiring board is suspended from a position on the other side of the mounting portion in the horizontal direction when the inspection object is the first type of inspection object, and suspended from a position on the one side of the mounting portion in the horizontal direction when the inspection object is the second type of inspection object. Therefore, even if the inspection object is of a different type, the orientation of the power receiving portion of the flexible wiring board of the inspection object can be set to an appropriate direction.
In the present invention, the following means may be employed: the substrate forms a display panel, and when the conveying mechanism conveys the adsorption head and the carrying part to one side in the horizontal direction, an imaging device is used for imaging the lighting state of the display panel.

Fig. 7 is a diagram illustrating a process of inspecting the second type of display panel 100B by the inspection apparatus 1.
The inspection apparatus 1 of the present embodiment is an apparatus for performing lighting inspection on a display panel 100 as an inspection object. As will be described below, the inspection apparatus 1 is configured to be able to inspect any type of display panel 100, out of the first type of display panel 100A and the second type of display panel 100B. Therefore, in fig. 3, the flexible wiring board 111 in the case where the display panel 100 to be inspected is the first type of display panel 100A is indicated by a solid line, and the flexible wiring board 111 in the case where the display panel 100 to be inspected is the second type of display panel 100B is indicated by a broken line. As shown in fig. 3, the inspection apparatus 1 includes: a mounting portion 2 for mounting the flexible wiring board 111 such that one surface 112 faces one side in the horizontal direction when the board is hung down; and an attitude correction suction head 3 for sucking the flexible wiring board 111 by rotating the suspended flexible wiring board 111 so as to overlap the board 101 from below, and then rotating the flexible wiring board 111 in the opposite direction to set the flexible wiring board 111 in a state suspended in the vertical direction. The inspection apparatus 1 further includes: a suction head 4 for sucking a rear surface portion of the power supply receiving portion 115 on the other surface 119 of the flexible wiring board 111 hanging down in the vertical direction; an inspection power supply unit 5 facing the power supply unit 115 in a state where the flexible wiring board 111 is adsorbed to the adsorption head 4 on one side in the horizontal direction; a conveyance mechanism 6 that moves the suction head 4 and the placement unit 2 to one side in the horizontal direction while the suction of the flexible wiring board 111 by the posture-correcting suction head 3 is stopped, and electrically connects the power-supplied unit 115 and the inspection power-supply unit 5; and a photographing device 7. In the present embodiment, the posture-correcting suction head 3 includes a first posture-correcting suction head 31 and a second posture-correcting suction head 36. The first posture-correcting suction head 31 and the second posture-correcting suction head 36 are disposed at positions apart from each other in the horizontal direction. In the present specification, the axis along the vertical direction is referred to as the Z axis, the axis orthogonal to the Z axis in the direction along which the suction head 4 is conveyed by the conveying mechanism 6 is referred to as the X axis, and the axis orthogonal to the X axis and the Z axis is referred to as the Y axis. The X-axis direction and the Y-axis direction are horizontal directions. As shown in fig. 1 (a) and 1 (B), the direction in which the inspection power supply unit 5 is located is defined as one side X1 and the opposite direction is defined as the other side X2 on the X axis. On the Z axis, the upper side is Z1, and the lower side is Z2.
(inspection of first type display Panel 100A)
First, a case where the inspection apparatus 1 inspects the first type of display panel 100A will be described. As shown in fig. 4, the mounting portion 2A includes a mounting surface portion 21 on which the back surface 103 of the substrate 101 is mounted, and an opening portion 22 for drawing out the flexible wiring board 111. The opening 22 is located near the other side X2 of the mounting portion 2A, and is cut out from an end 26 of the other side X2 of the mounting portion 2A. The opening 22 is rectangular when viewed in the Z-axis direction.
As shown in fig. 4, the mounting surface 21 is provided with a plurality of suction holes 24 for sucking the back surface 103 of the substrate 101. The back surface 103 of the substrate 101 placed on the placement surface 21 is fixed by being sucked by the suction holes 24. The suction by the suction holes 24 is performed by a pump not shown. In the present embodiment, the placement unit 2A is connected to the conveying mechanism 6 via the base 8. Therefore, the placement unit 2A is conveyed to the side X1 by the conveying mechanism 6.
In the case of inspecting the first type of display panel 100A, only the first posture-correcting suction head 31 is used. At this time, the second posture-correcting suction head 36 is positioned by the actuator 39 at a position Z1 above the mounting portion 2A. As shown in fig. 3 and 4, the first posture-correcting suction head 31 is located on the other side X2 with respect to the mounting portion 2A. The first posture-correcting suction head 31 is rotatable about an axis extending along the Y axis by a rotating portion 32. Therefore, as will be described later, the first posture-correcting suction head 31 rotates so that the suspended flexible wiring board 111 overlaps the board 101 from below, and after sucking the flexible wiring board 111, rotates in the opposite direction so that the flexible wiring board 111 is set to be suspended in the vertical direction.
The first posture-correcting suction head 31 has a rectangular shape. The first posture-correcting suction head 31 is sized to be accommodated in the opening 22 when the rotating portion 32 rotates the suspended flexible wiring board 111 so as to overlap the board 101 from below. The suction surface 311 of the first posture-correcting suction head 31 is provided with a plurality of suction holes 312 for sucking the main body 114 of the flexible wiring board 111.
As shown in fig. 3 and 4, the suction head 4 is positioned below Z2 with respect to the first posture-correcting suction head 31. The suction head 4 includes a suction portion 41 that sucks the other surface 119 (the second side surface 117) of the front end portion 113 of the flexible wiring board 111, and an actuator 42 that moves the suction portion 41 in the X-axis direction. The suction surface 43 of the suction portion 41 is provided with a plurality of suction holes 44 for sucking the other surface 119 of the front end portion 113 of the flexible wiring board 111. The actuator 42 is, for example, an electric cylinder or an air cylinder. When the suction portion 41 sucks the front end portion 113 of the flexible wiring board 111, the actuator 42 adjusts the position in the X-axis direction.
The conveying mechanism 6 is, for example, an electric cylinder or an air cylinder. The transport mechanism 6 is connected to an actuator 42 of the suction head 4, and can reciprocate the suction head 4 in the X-axis direction. Therefore, as described later, the conveyance mechanism 6 conveys the suction head 4 to the side X1 on which the inspection power supply unit 5 is located. The transport mechanism 6 moves the suction head 4 to one side X1, and electrically connects the power receiving unit 115 and the inspection power feeding unit 5.
The inspection power supply unit 5 includes a plurality of probe units 51 electrically contacting the power supply unit 115 of the flexible wiring board 111. When inspecting the display panel 100, electricity is supplied from the probe portion 51 to the display panel 100. The inspection power supply unit 5 includes a probe holding unit 52 that holds the probe unit 51, a position adjusting unit 53 that adjusts the position of the probe holding unit 52, and a monitor 54 that detects the position of the power supply unit 115A. The monitoring device 54 is constituted by a line sensor, a zone sensor, and the like. The position adjustment unit 53 adjusts the position of the probe holding unit 52 in the X-axis direction, the Y-axis direction, the Z-axis direction, and the rotational direction about the axis extending along the X-axis, based on the position of the power feeding unit 115A detected by the monitoring device 54. More specifically, the position adjustment unit 53 adjusts the relative position of the connector 118 of the power-supplied unit 115A and the probe unit 51 based on the position of the power-supplied unit 115A detected by the monitoring device 54 so that the connector 118 of the power-supplied unit 115A is properly brought into contact with the probe unit 51.
As described later, when the display panel 100 is energized, the imaging device 7 images the lit state of the display panel 100. The imaging device 7 is constituted by a line sensor, a region sensor, and the like.
Next, an inspection process of the first type display panel 100A will be described with reference to fig. 5. As shown in fig. 5, in step ST1, when the first type display panel 100A is mounted on the mounting portion 2A, the back surface 103 of the substrate 101 is fixed by being attracted to the attraction holes 24. At this time, the flexible wiring board 111 hangs down from a position near the other side X2 in the X-axis direction.
In step ST2, the first posture-correcting suction head 31 is rotated by the rotating unit 32 so that the suspended flexible wiring board 111 overlaps the rear surface 103 of the board 101 from the lower side Z2. When the suspended flexible wiring board 111 is overlapped with the back surface 103 of the board 101, the first posture-correcting suction head 31 sucks the main body 114 of the flexible wiring board 111.
In step ST3, the first posture-correcting suction head 31 is rotated in the opposite direction by the rotating unit 32, and the flexible wiring board 111 is set to a state hanging down in the Z direction. Then, the suction head 4 moves the suction portion 41 to one side X1 by the actuator 42, and the suction surface 43 is brought into contact with the other surface 119 of the front end portion 113 of the flexible wiring board 111. The suction hole 44 sucks a rear surface portion of the connector 118 on the other surface 119 (the second side surface 117) of the front end portion 113 of the flexible wiring board 111. After the suction head 4 sucks the distal end portion 113 of the flexible wiring board 111, the suction head 31 for correcting the first posture stops sucking the main body portion 114 of the flexible wiring board 111.
In step ST4, the conveyance mechanism 6 conveys the suction head 4 and the placement unit 2A to the side X1 in a state where the front end portion 113 of the flexible wiring board 111 has been held. More specifically, the conveying mechanism 6 conveys the suction head 4 to the inspection power supply unit 5, and conveys the mounting unit 2A to a position below the imaging device 7Z 2. At this time, the position adjustment unit 53 adjusts the relative position of the connector 118 of the power-supplied unit 115A and the probe unit 51 based on the position of the connector 118 of the power-supplied unit 115A detected by the monitoring device 54, so that the connector 118 of the power-supplied unit 115A and the probe unit 51 are properly connected. The transport mechanism 6 electrically connects the connector 118 of the power receiving portion 115A with the probe portion 51. When the probe portion 51 is connected to the connector 118 of the power receiving portion 115A, power is supplied from the inspection power supply portion 5, and an inspection image is displayed on the display portion 102 of the first type display panel 100A. At this time, the first type display panel 100A is lighted by a light source (not shown) disposed below the mounting portion 2A at Z2. The inspection apparatus 1 inspects whether or not the display section 102 of the first type of display panel 100A has a defect by photographing the lit state of the display section 102 of the first type of display panel 100A by the photographing apparatus 7. When the inspection is completed, the conveying mechanism 6 conveys the mounting portion 2A and the suction head 4 to the position before the inspection (the other side X2). After that, the suction of the rear surface 103 of the substrate 101 and the front end 113 of the flexible wiring board 111 is stopped.
(inspection of display Panel 100B of the second type)
Next, a case where the inspection apparatus 1 inspects the second type of display panel 100B will be described. In addition, the description is omitted for the portions having the same structure as the case of inspecting the first type of display panel 100A.
As shown in fig. 6, the mounting portion 2B includes a mounting surface portion 21 on which the back surface 103 of the substrate 101 is mounted, and an opening portion 22 for drawing out the flexible wiring board 111. The opening 22 is located near one side Z1 of the mounting portion 2B, and is cut out from an end 27 of one side X1 of the mounting portion 2B. That is, when the inspection apparatus 1 inspects the first type of display panel 100A and the second type of display panel 100B, the directions in which the openings 22 are located are different. The inspection device 1 of the present embodiment selectively disposes the mounting portion 2A and the mounting portion 2B to the base portion 8 according to the type of the display panel 100 to be inspected.
In the case of inspecting the second type of display panel 100B, only the second posture-correcting suction head 36 is used. As shown in fig. 6 and 7, the second posture-correcting suction head 36 is positioned on one side X1 with respect to the mounting portion 2B. The second posture-correcting suction head 36 is rotated by the rotating unit 37 so that the suspended flexible wiring board 111 overlaps the board 101 from below, and after the flexible wiring board 111 is sucked, is rotated in the opposite direction, and is rotated so that the flexible wiring board 111 is set to be suspended in the vertical direction.
The second posture-correcting suction head 36 is rectangular. The second posture-correcting suction head 36 is sized to be accommodated in the opening 22 when the suspended flexible wiring board 111 is rotated by the rotating unit 37 so as to overlap the board 101 from below. The suction surface 361 of the second posture-correcting suction head 36 is provided with a plurality of suction holes 362 for sucking the main body 114 of the flexible wiring board 111.
The second posture-correcting suction head 36 is moved in the Z-axis direction by an actuator 39 via a rotating portion 37. In the case of inspecting the first type of display panel 100A, the actuator 39 moves the second posture-correcting suction head 36 upward Z1 via the rotating portion 37. In the case of inspecting the second type of display panel 100B, the actuator 39 moves the second posture-correcting suction head 36 via the rotating portion 37 to the lower direction Z2. When the mounting portion 2 is conveyed to the one side X1 by the conveying mechanism 6, the actuator 39 moves the second posture-correcting suction head 36 upward Z1 via the rotating portion 37.
Next, an inspection process of the second type display panel 100B will be described with reference to fig. 7. As shown in fig. 7, in step ST1, when the second type display panel 100B is mounted on the mounting portion 2B, the rear surface 103 of the substrate 101 is fixed by being attracted to the attraction holes 24. At this time, the flexible wiring board 111 hangs down from a position near one side X1 in the X-axis direction. And hangs downward from the opening 22. The actuator 39 moves the second posture-correcting suction head 36 downward Z2.
In step ST2, the second posture-correcting suction head 36 is rotated by the rotating unit 37 so that the suspended flexible wiring board 111 overlaps the rear surface 103 of the board 101 from the lower side Z2. When the suspended flexible wiring board 111 is overlapped with the back surface 103 of the board 101, the second posture-correcting suction head 36 sucks the main body 114 of the flexible wiring board 111.
In step ST3, the second posture-correcting suction head 36 is rotated in the opposite direction by the rotating unit 37, and the flexible wiring board 111 is set to a state hanging down in the Z direction. Then, the suction head 4 moves the suction portion 41 to one side X1 by the actuator 42, and the suction surface 43 is brought into contact with the rear surface portion of the connector 118 on the other surface 119 (first side surface 116) of the front end portion 113 of the flexible wiring board 111. The suction hole 44 sucks the other surface 119 of the front end portion 113 of the flexible wiring board 111. After the suction head 4 sucks the distal end portion 113 of the flexible wiring board 111, the second posture-correcting suction head 36 stops sucking the main body portion 114 of the flexible wiring board 111.
In step ST4, the second posture-correcting suction head 36 is moved upward Z1 by the actuator 39. Thereafter, the conveying mechanism 6 conveys the suction head 4 and the placement unit 2B to the side X1 while holding the front end 113 of the flexible wiring board 111. More specifically, the conveying mechanism 6 conveys the suction head 4 to the vicinity of the inspection power supply unit 5, and conveys the mounting unit 2B to a position below the imaging device 7Z 2. At this time, the position adjustment unit 53 adjusts the relative position of the connector 118 of the power-supplied unit 115B and the probe unit 51 based on the position of the connector 118 of the power-supplied unit 115B detected by the monitoring device 54, so that the connector 118 of the power-supplied unit 115B and the probe unit 51 are properly connected. The transport mechanism 6 electrically connects the connector 118 of the power receiving portion 115B with the probe portion 51. When the probe portion 51 is connected to the connector 118 of the power receiving portion 115B, power is supplied from the inspection power supply portion 5, and an inspection image is displayed on the display portion 102 of the second type display panel 100B. At this time, the second type display panel 100B is lighted by a light source (not shown) disposed below the mounting portion 2B Z2. The inspection apparatus 1 inspects whether or not the display portion 102 of the second type of display panel 100B has a defect by photographing the lit state of the display portion 102 of the second type of display panel 100B by the photographing apparatus 7. When the inspection is completed, the conveying mechanism 6 conveys the mounting portion 2B and the suction head 4 to the position before the inspection (the other side X2). After that, the suction of the rear surface 103 of the substrate 101 and the front end 113 of the flexible wiring board 111 is stopped.
(main effects of the present embodiment)
The inspection apparatus 1 of the present embodiment includes: a mounting portion 2 for mounting the substrate 101 such that, when the flexible wiring board 111 hangs down, the surface 112 provided with the power-supplied portion 115 faces one side in the horizontal direction (one side X1 in the X-axis direction); an attitude correction suction head 3 for sucking the flexible wiring board 111 by rotating the suspended flexible wiring board 111 so as to overlap the board 101 from the lower side Z2, and then rotating the flexible wiring board in the opposite direction, thereby setting the flexible wiring to be suspended in the vertical direction; and a suction head 4 for sucking a rear surface portion of the power supply portion 115 on the other surface 119 of the flexible wiring board 111 which is suspended in the vertical direction. Therefore, even in the flexible wiring board 111 in the free posture, the posture-correcting suction head 3 can be set in a state of being hung down in the vertical direction, and the suction head 4 can suction the rear surface portion of the power-supplied portion 115 on the other surface 119 of the flexible wiring board 111 hanging down in the vertical direction. The inspection apparatus 1 further includes: an inspection power supply unit 5 facing the power supply unit 115 in a state where the flexible wiring board 111 is adsorbed to the adsorption head 4 on one side X1 in the horizontal direction; and a conveying mechanism 6 for moving the suction head 4 and the placement unit 2 to one side X1 in the horizontal direction in a state in which suction of the flexible wiring board 111 by the suction head 3 for posture correction is stopped, and electrically connecting the power receiving unit 115 and the power feeding unit 5 for inspection. Therefore, the conveyance mechanism 6 can move the suction head 4 and the mounting portion 2 to one side X1 in the horizontal direction, and electrically connect the power receiving portion 115 and the inspection power feeding portion 5. As a result, the inspection device 1 of the present embodiment can perform automation of inspection even for the display panel 100 including the flexible wiring board 111.
In the present embodiment, the monitoring device 54 for detecting the position of the power receiving unit 115 is provided, and when the power receiving unit 115 is electrically connected to the inspection power feeding unit 5, the relative position of the power receiving unit 115 and the probe unit 51 of the inspection power feeding unit 5 is adjusted based on the monitoring result of the monitoring device 54. The power receiving unit 115 includes a connector 118. Therefore, since the position of the probe portion 51 of the inspection power supply portion 5 can be adjusted with respect to the connector 118 of the power supply portion 115, the connector 118 of the power supply portion 115 and the probe portion 51 of the inspection power supply portion 5 can be reliably connected.
In the present embodiment, as the posture-correcting suction head 3, the first posture-correcting suction head 31 and the second posture-correcting suction head 36 are disposed at positions separated in the horizontal direction, and the display panel 100 includes: when the flexible wiring board 111 is overlapped with the substrate 101 from the lower Z2 in the vertical direction, the first type display panel 100A having one surface 112 facing the first side surface 116 of the substrate 101 and the second type display panel 100B having one surface 112 facing the second side surface 117 on the opposite side of the substrate 101 are set to a state in which the flexible wiring board 111 hangs down in the vertical direction by the first posture correction suction head 31 in the case of the first type display panel 100A and the flexible wiring board 111 hangs down in the vertical direction by the second posture correction suction head 36 in the case of the second type display panel 100B. Accordingly, the flexible wiring board 111 can be set to a state hanging down in the vertical direction by the first posture correcting suction head 31 and the second posture correcting suction head 36 regardless of the display panel 100 of the type in which the power receiving portion 115 of the flexible wiring board 111 is oriented, that is, any one of the first type of display panel 100A and the second type of display panel 100B.
In the present embodiment, the mounting portion 2 includes an opening 22 for drawing out the flexible wiring board 111, and in the mounting portion 2, when the display panel 100 is the first type of display panel 100A, the opening 22 is located at a position closer to the other side X2 in the horizontal direction of the mounting portion 2. Therefore, the flexible wiring board 111 can be set to a state hanging down from a position near the other side X2 in the X-axis direction. In contrast, when the display panel 100 is the second type display panel 100B, the opening 22 is located at a position closer to the horizontal side X1 of the mounting portion 2 in the mounting portion 2. Therefore, the flexible wiring board 111 can be set to a state hanging down from a position near the one side X1 in the X-axis direction. Therefore, even if the display panel 100 is of a different type, the orientation of the power-supplied portion 115 of the flexible wiring substrate 111 can be set to an appropriate direction.
