Disclosure of Invention
Technical problem to be solved by the invention
The inspection object may be inspected while having a flexible wiring board. However, the inspection apparatus of patent document 1 is an inspection apparatus that automatically inspects an inspection object that does not have a flexible wiring board, and cannot inspect an inspection object 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 portion, and then a power supply portion for inspection is electrically connected to a power supply portion for power supply of the flexible wiring board by manual work of an operator. As a result, the inspection apparatus cannot automatically inspect the inspection target, and therefore, there is a problem in that the inspection time for the inspection target becomes long.
The present invention has been made to solve the above-described problems, and provides an inspection apparatus capable of automatically inspecting even an inspection object having a flexible wiring board.
Technical solution for solving technical problem
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 receiving portion being provided on one surface side of the other end of the flexible wiring board, the inspection apparatus including: 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 substrate is hung down; a suction head for posture correction that rotates the suspended flexible wiring board from below so as to overlap the board, thereby sucking 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 of being suspended in the vertical direction; an adsorption head for adsorbing a back surface portion of the power supply receiving portion on the other surface of the flexible wiring board that is vertically suspended; a power supply unit for inspection, which is opposed to the power supply unit in a state where the flexible wiring board is attracted to the attraction head on one side in a horizontal direction; and a conveying mechanism that moves the suction head and the placement unit to one side in the horizontal direction so as to electrically connect the power supply target unit and the inspection power supply unit, in a state where suction of the flexible wiring board by the suction head for posture correction is stopped.
According to the present invention, even in a flexible wiring board having 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 portion of the power-supplied portion on the other surface of the flexible wiring board hanging in the vertical direction. The conveying mechanism can move the adsorption head and the carrying part to one side in the horizontal direction to electrically connect the power supply part for the inspection and the power supply part for the power supply. As a result, the inspection device of the present invention can automate the inspection even for an inspection object provided with a flexible wiring board.
In the present invention, it is preferable that a monitoring device for detecting a position of the power-supplied portion is provided, and when the power-supplied portion and the inspection power-supplying portion are electrically connected, a relative position of the power-supplied portion and the inspection power-supplying portion is adjusted based on a monitoring result of the monitoring device. In the present invention, it is preferable that the power-supplied portion includes a connector. Therefore, the position of the power supply unit for inspection can be adjusted with respect to the power supply unit, and therefore the power supply unit for inspection and the power supply unit for inspection can be reliably connected.
In the present invention, it is preferable that, as the posture-correcting suction head, a first posture-correcting suction head and a second posture-correcting suction head are disposed at positions separated in the horizontal direction, the object to be inspected includes a first type object to be inspected and a second type object to be inspected, when the flexible wiring board is overlapped with the substrate from the lower side in the vertical direction, the one surface of the first type of inspection object faces the surface of the substrate side, the one surface of the second type of inspection object faces a surface on the opposite side of the substrate, in the case of the first type of inspection object, the flexible wiring board is set in a vertically-suspended state by the first posture-correcting suction head, in the case of the second type of inspection object, the flexible wiring board is set in a vertically-suspended state by the second posture-correcting suction head. Therefore, regardless of the type of the inspection object in which direction the one surface of the flexible wiring board faces, that is, any of the first type of the inspection object and the second type of the inspection object, the first posture-correcting suction head and the second posture-correcting suction head can set the flexible wiring board in a state of hanging down in the vertical direction.
In the present invention, it is preferable that the mounting unit includes an opening portion for drawing out the flexible wiring board downward, and the flexible wiring board is hung from a position on the other side of the mounting unit in the horizontal direction when the inspection object is the first type of inspection object, and the flexible wiring board is hung from a position on the one side of the mounting unit in the horizontal direction when the inspection object is the second type of inspection object. Therefore, even if the inspection target object is of a different type, the orientation of the power-supplied portion of the flexible wiring board of the inspection target object can be set to an appropriate direction.
In the present invention, the following modes can be adopted: the substrate constitutes a display panel, and when the conveyance mechanism conveys the suction head and the placement unit to one side in the horizontal direction, a lighting state of the display panel is photographed by a photographing device.

Fig. 7 is a diagram illustrating a process of inspecting the second type display panel 100B by the inspection apparatus 1.
The inspection apparatus 1 of the present embodiment is an apparatus for performing a lighting inspection of a display panel 100 as an inspection object. As described below, the inspection apparatus 1 is configured to be capable of inspecting any type of display panel 100 of the first type display panel 100A and the second type display panel 100B. Therefore, in fig. 3, the flexible wiring board 111 is indicated by solid lines when the display panel 100 to be inspected is the first type display panel 100A, and the flexible wiring board 111 is indicated by broken lines when the display panel 100 to be inspected is the second type display panel 100B. As shown in fig. 3, the inspection apparatus 1 includes: a mounting unit 2 on which the flexible wiring board 111 is mounted such that one surface 112 faces one side in the horizontal direction when the board hangs down; and a posture-correcting suction head 3 that sucks the flexible wiring board 111 by rotating the flexible wiring board 111 that hangs down so as to overlap the substrate 101 from below, and then rotates the suction head in the opposite direction to set the flexible wiring board 111 in a state of hanging down in the vertical direction. Further, the inspection apparatus 1 includes: an adsorption head 4 which adsorbs a rear surface portion of the power-supplied portion 115 on the other surface 119 of the flexible wiring board 111 which is vertically suspended; a power supply unit 5 for inspection, which is opposed to a power supply unit 115 in a state where the flexible wiring board 111 is attracted to the suction head 4, on one side in the horizontal direction; a conveyance mechanism 6 for moving the suction head 4 and the placement unit 2 to one side in the horizontal direction while stopping suction of the flexible wiring board 111 by the posture-correcting suction head 3, and electrically connecting the power-supplied unit 115 and the inspection power-supplying unit 5; and a camera 7. In the present embodiment, the posture-correcting suction head 3 includes the first posture-correcting suction head 31 and the second posture-correcting suction head 36. The first posture-correction suction head 31 and the second posture-correction suction head 36 are disposed at positions separated in the horizontal direction. In this specification, an axis along the vertical direction is referred to as a Z axis, an axis orthogonal to the Z axis and along the direction in which the suction head 4 is conveyed by the conveying mechanism 6 is referred to as an X axis, and an axis orthogonal to the X axis and the Z axis is referred to as a 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 of the inspection power supply unit 5 is one side X1 and the opposite direction is 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 the first type display Panel 100A)
First, a case where the inspection apparatus 1 inspects the display panel 100A of the first type will be described. As shown in fig. 4, the mounting portion 2A includes a mounting surface portion 21 for mounting the rear surface 103 of the substrate 101 and an opening 22 for leading out the flexible wiring substrate 111. Opening 22 is located at a position closer to the other side X2 of mounting portion 2A, and is cut out from end 26 of the other side X2 of mounting portion 2A. The opening 22 is rectangular when viewed from the Z-axis direction.
As shown in fig. 4, the mounting surface portion 21 is provided with a plurality of suction holes 24 for sucking the rear surface 103 of the substrate 101. The back surface 103 of the substrate 101 placed on the placement surface portion 21 is sucked and fixed by the suction holes 24. The suction through the suction hole 24 is performed by a pump not shown. In the present embodiment, the placement unit 2A is connected to the conveyance 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 adsorption head 31 is used. At this time, the second posture-correcting suction head 36 is positioned above the mount unit 2A by the actuator 39 at Z1. As shown in fig. 3 and 4, the first posture-correction suction head 31 is positioned on the other side X2 with respect to the placement unit 2A. The first posture-correcting adsorption head 31 is rotatable about an axis extending along the Y axis by the rotation section 32. Therefore, as will be described later, the first posture-correcting suction head 31 rotates so that the flexible wiring board 111 hanging down overlaps the substrate 101 from below, and rotates in the opposite direction after sucking the flexible wiring board 111, thereby setting the flexible wiring board 111 in a state hanging down 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 suspended flexible wiring board 111 is rotated by the rotating portion 32 so as to overlap the substrate 101 from below. A plurality of suction holes 312 for sucking the main body portion 114 of the flexible wiring board 111 are provided in the suction surface 311 of the first posture-correcting suction head 31.
As shown in fig. 3 and 4, the suction head 4 is positioned at the lower Z2 with respect to the first posture-correction suction head 31. The suction head 4 includes a suction portion 41 that sucks the other surface 119 (second side surface 117) of the distal 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 unit 41 is provided with a plurality of suction holes 44 for sucking the other surface 119 of the distal 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 unit 41 sucks the distal end portion 113 of the flexible wiring board 111, the actuator 42 adjusts the position in the X-axis direction.
The transport 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 will be described later, the conveying mechanism 6 conveys the suction head 4 to the side X1 where the inspection power supply unit 5 is located. The conveyance mechanism 6 moves the suction head 4 to one side X1, and electrically connects the power supply unit 115 to the inspection power supply unit 5.
The inspection power supply unit 5 includes a plurality of probe portions 51 electrically contacting the power supply target portions 115 of the flexible wiring board 111. When the display panel 100 is inspected, electricity is supplied from the probe unit 51 to the display panel 100. The inspecting power feeding unit 5 includes a probe holding unit 52 for holding the probe unit 51, a position adjusting unit 53 for adjusting the position of the probe holding unit 52, and a monitoring device 54 for detecting the position of the power-fed unit 115A. The monitoring device 54 is constituted by a line sensor, an area sensor, and the like. The position adjusting 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 fed portion 115A detected by the monitoring device 54. More specifically, the position adjustment unit 53 adjusts the relative positions of the connector 118 of the fed portion 115A and the probe unit 51 so that the connector 118 of the fed portion 115A and the probe unit 51 appropriately contact each other, based on the position of the fed portion 115A detected by the monitoring device 54.
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 configured by a line sensor, an area 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 placed on the placement unit 2A, the back surface 103 of the substrate 101 is sucked and fixed by the suction holes 24. At this time, the flexible wiring board 111 hangs down from a position closer to the other side X2 in the X axis direction.
In step ST2, the first posture-correcting suction head 31 is rotated by the rotating section 32 so that the suspended flexible wiring board 111 overlaps the back surface 103 of the substrate 101 from below Z2. When the hanging flexible wiring board 111 is overlapped with the back surface 103 of the substrate 101, the first posture-correcting suction head 31 sucks the main body portion 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 section 32, and the flexible wiring board 111 is set in a state of hanging down in the Z direction. Then, the suction head 4 moves the suction portion 41 to the side X1 by the actuator 42, and brings the suction surface 43 into contact with the other surface 119 of the distal 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 (second side surface 117) of the front end portion 113 of the flexible wiring substrate 111. After the suction head 4 sucks the front end portion 113 of the flexible wiring board 111, the first posture-correcting suction head 31 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, which have held the distal end portion 113 of the flexible wiring board 111, to one side X1. More specifically, the transport mechanism 6 transports the suction head 4 to the inspection power supply unit 5, and transports the placement unit 2A to a position Z2 below the imaging device 7. At this time, the position adjusting unit 53 adjusts the relative positions of the connector 118 of the power receiving unit 115A and the probe unit 51 so that the connector 118 of the power receiving unit 115A and the probe unit 51 are appropriately connected, based on the position of the connector 118 of the power receiving unit 115A detected by the monitoring device 54. The conveyance mechanism 6 electrically connects the connector 118 of the power-supplied portion 115A to the probe portion 51. When the probe unit 51 is connected to the connector 118 of the power-supplied unit 115A, power is supplied from the inspection power-supplying unit 5, and an inspection image is displayed on the display unit 102 of the first type display panel 100A. At this time, the first type display panel 100A is turned on by a light source (not shown) disposed below the placement unit 2A at Z2. The inspection apparatus 1 inspects whether or not the display portion 102 of the first type display panel 100A has a defect by photographing the lighting state of the display portion 102 of the first type display panel 100A by the photographing apparatus 7. When the inspection is completed, the transport mechanism 6 transports the placement unit 2A and the suction head 4 to the position before the inspection (the other side X2). Thereafter, the suction to the back surface 103 of the substrate 101 and the front end portion 113 of the flexible wiring substrate 111 is stopped.
(inspection of the second type display Panel 100B)
Next, a case where the inspection apparatus 1 inspects the display panel 100B of the second type will be described. Note that, for portions having the same structure as the case of inspecting the first type of display panel 100A, description is omitted.
As shown in fig. 6, the mounting portion 2B includes a mounting surface portion 21 for mounting the rear surface 103 of the substrate 101 and an opening 22 for leading out the flexible wiring substrate 111. Opening 22 is located close to side Z1 of mounting portion 2B, and is cut out from end 27 of side X1 of mounting portion 2B. That is, the direction in which the opening 22 is located differs between when the inspection apparatus 1 inspects the first type display panel 100A and when it inspects the second type display panel 100B. The inspection apparatus 1 of the present embodiment selectively arranges the placement portion 2A and the placement 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-correction suction head 36 is positioned on one side X1 with respect to the placement unit 2B. The second posture-correcting suction head 36 is rotated by the rotating section 37 so that the flexible wiring board 111 hanging down is overlapped with the substrate 101 from below, and after sucking the flexible wiring board 111, is rotated in the opposite direction, and is rotated so that the flexible wiring board 111 is set in a state of hanging down in the vertical direction.
The second posture-correcting suction head 36 has a rectangular shape. 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 portion 37 so as to overlap the substrate 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 portion 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 unit 37. When the first type of display panel 100A is inspected, the actuator 39 moves the second posture-correction suction head 36 upward Z1 via the rotating portion 37. When the second type display panel 100B is inspected, the actuator 39 moves the second posture-correcting suction head 36 downward Z2 via the rotating portion 37. When the placement unit 2 is conveyed to the side X1 by the conveyance mechanism 6, the actuator 39 moves the second posture-correction suction head 36 upward Z1 via the rotation unit 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 placed on the placement unit 2B, the back surface 103 of the substrate 101 is sucked and fixed by the suction holes 24. At this time, the flexible wiring board 111 hangs down from a position close to one side X1 in the X axis direction. Hanging downward from the opening 22. Further, the actuator 39 moves the second posture-correction 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 back surface 103 of the substrate 101 from below Z2. When the hanging flexible wiring board 111 is overlapped with the back surface 103 of the substrate 101, the second posture-correcting suction head 36 sucks the main body portion 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 in a state of hanging down in the Z direction. Then, the suction head 4 moves the suction portion 41 to the side X1 by the actuator 42, and brings the suction surface 43 into contact with the rear surface portion of the connector 118 on the other surface 119 (first side surface 116) of the distal end portion 113 of the flexible wiring board 111. The suction hole 44 sucks the other surface 119 of the distal end portion 113 of the flexible wiring board 111. After the suction head 4 sucks the front 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. After that, the transport mechanism 6 transports the suction head 4 and the placement portion 2B to the side X1 in a state where the distal end portion 113 of the flexible wiring substrate 111 is held. More specifically, the transport mechanism 6 transports the suction head 4 to the vicinity of the inspection power supply unit 5, and transports the placement unit 2B to a position Z2 below the imaging device 7. At this time, the position adjusting unit 53 adjusts the relative positions of the connector 118 of the power receiving unit 115B and the probe unit 51 so that the connector 118 of the power receiving unit 115B and the probe unit 51 are appropriately connected, based on the position of the connector 118 of the power receiving unit 115B detected by the monitoring device 54. The conveyance mechanism 6 electrically connects the connector 118 of the power-supplied portion 115B and the probe portion 51. When the probe unit 51 is connected to the connector 118 of the power-supplied unit 115B, power is supplied from the inspection power-supplying unit 5, and an inspection image is displayed on the display unit 102 of the second type display panel 100B. At this time, the second type display panel 100B is lit by a light source (not shown) disposed below the placement unit 2B at Z2. The inspection apparatus 1 images the lighting state of the display portion 102 of the second type display panel 100B by the imaging apparatus 7, and inspects whether or not the display portion 102 of the second type display panel 100B has a defect. When the inspection is completed, the conveying mechanism 6 conveys the placement unit 2B and the suction head 4 to the position before the inspection (the other side X2). Thereafter, the suction to the back surface 103 of the substrate 101 and the front end portion 113 of the flexible wiring substrate 111 is stopped.
(main effects of the present embodiment)
The inspection apparatus 1 of the present embodiment includes: a mounting unit 2 for mounting the substrate 101 such that the surface 112 on which the power receiving unit 115 is provided faces one side in the horizontal direction (one side X1 in the X-axis direction) when the flexible wiring substrate 111 is suspended; a posture-correcting suction head 3 that sucks the flexible wiring board 111 by rotating the suspended flexible wiring board 111 from below Z2 so as to overlap the substrate 101, and then rotates the suction head in the opposite direction to set the flexible wiring in a state suspended in the vertical direction; and an adsorption head 4 which adsorbs a rear surface portion of the power-supplied portion 115 on the other surface 119 of the flexible wiring board 111 which is vertically suspended. Therefore, even in the flexible wiring board 111 having a free posture, the suction head 3 for posture correction can be set in a state of hanging down in the vertical direction, and the suction head 4 can suck the back 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. Further, the inspection apparatus 1 includes: a power supply unit 5 for inspection, which is opposed to the power supply receiving unit 115 in a state where the flexible wiring board 111 is attracted to the suction head 4, at one side X1 in the horizontal direction; and a conveyance mechanism 6 for moving the suction head 4 and the placement unit 2 to one side X1 in the horizontal direction while stopping suction of the flexible wiring board 111 by the posture-correcting suction head 3, and electrically connecting the power-supplied unit 115 and the inspection power-supplying unit 5. Therefore, the conveyance mechanism 6 can move the suction head 4 and the placement unit 2 to one side X1 in the horizontal direction to electrically connect the power supply unit for inspection 115 and the power supply unit for inspection 5. As a result, the inspection apparatus 1 of the present embodiment can automate the inspection even with the display panel 100 including the flexible wiring board 111.
In the present embodiment, the power supply unit is provided with a monitoring device 54 for detecting the position of the power supply target portion 115, and when the power supply target portion 115 is electrically connected to the inspection power supply portion 5, the relative position between the power supply target portion 115 and the probe portion 51 of the inspection power supply portion 5 is adjusted based on the monitoring result of the monitoring device 54. The power-supplied portion 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-supplied portion 115, the connector 118 of the power-supplied portion 115 and the probe portion 51 of the inspection power supply portion 5 can be reliably connected.
In the present embodiment, the first posture-correction suction head 31 and the second posture-correction suction head 36 are disposed at positions separated in the horizontal direction as the posture-correction suction head 3, and the display panel 100 includes: when the flexible wiring board 111 is superimposed on the substrate 101 from the lower side Z2 in the vertical direction, the first type display panel 100A having the first side surface 116 of the substrate 101 facing the first side surface 112 and the second type display panel 100B having the second side surface 117 opposite to the substrate 101 facing the first side surface 112 are set in a state where the flexible wiring board 111 is suspended in the vertical direction by the first posture-correcting suction head 31 in the case of the first type display panel 100A, and the flexible wiring board 111 is set in a state where the flexible wiring board 111 is suspended in the vertical direction by the second posture-correcting suction head 36 in the case of the second type display panel 100B. Therefore, regardless of the type of the display panel 100 in which the power-supplied portion 115 of the flexible wiring substrate 111 is oriented, that is, any of the first type of the display panel 100A and the second type of the display panel 100B, the first posture-correcting suction head 31 and the second posture-correcting suction head 36 can set the flexible wiring substrate 111 in a state of hanging down in the vertical direction.
In the present embodiment, the mounting unit 2 includes the opening 22 for drawing the flexible wiring board 111, and when the display panel 100 is the first type display panel 100A in the mounting unit 2, the opening 22 is located at the other side X2 of the mounting unit 2 in the horizontal direction. Therefore, the flexible wiring board 111 can be set in a state of hanging down from a position closer to the other side X2 in the X axis direction. On the other hand, when the display panel 100 is the second type display panel 100B, the opening 22 is located at the position closer to the one side X1 in the horizontal direction of the mounting portion 2 in the mounting portion 2. Therefore, the flexible wiring board 111 can be set in a state of hanging down from a position close to one side X1 in the X axis direction. Therefore, even if the display panels 100 are of different types, the orientation of the power-supplied portion 115 of the flexible wiring substrate 111 can be set to an appropriate direction.
