Description

  The present invention relates to an apparatus for producing a display panel, and more particularly to a display panel production apparatus for confirming defects in production.

  Display panels such as liquid crystal displays and plasma displays are mounted so that an ACF tape is mounted on a panel serving as a substrate, an electronic component such as a drive IC is mounted on an anisotropic conductive film, and the ACF tape and each electronic component are electrically connected. Produced by crimping.

  When attaching the ACF tape, the ACF tape may be attached in a defective state, for example, the end of the ACF tape is bent. In addition, when electronic parts are attached, the electronic parts may be attached in a defective state, for example, the parts may be distorted. When the main pressure bonding is performed, it becomes difficult to peel off the ACF tape from the panel. For this reason, it is desired to detect an attachment failure of an ACF tape or an electronic component before the main pressure bonding.

  2. Description of the Related Art Conventionally, a technique for inspecting the quality of an ACF tape attached state by a recognition unit having a camera has been proposed (see, for example, Patent Document 1).

With this technique, it is possible to automatically determine the attachment failure of the ACF tape or electronic component.
JP 2001-83477 A

  However, the conventional technique has a problem that production efficiency is lowered due to a determination error.

  Conventionally, if it is determined that there is a mounting failure, the ACF tape at that location is not permanently bonded. For this reason, if there is a determination mistake, the part is separately pressure-bonded separately. In the case of such a determination error, the ACF tape itself was correctly attached, and a normal display panel could be produced by performing the main pressure bonding in a series of steps following the attachment of the ACF tape and the electronic component. Nevertheless, the separate main crimping operation reduces the production efficiency.

  In order to improve production efficiency, it is effective to detect misjudgment before the main press bonding. Therefore, it is conceivable that the operator visually confirms that a determination error has not been made before the main press bonding.

  However, in general, in a display panel production apparatus, a head for attaching an ACF tape and a head for attaching an electronic component operate on a surface facing an operator. For this reason, the mounting location of the ACF tape and electronic parts on the display panel is far from the operator. In particular, a large display panel exceeding 50 inches has recently been produced, and the distance from the operator to the mounting location tends to increase.

  In addition, in the space where the head is operated in the display panel production apparatus, no consideration is given to daylighting. Therefore, it cannot be said that there is sufficient brightness to visually check the mounting state.

  Thus, in the conventional display panel production apparatus, it is difficult for an operator to visually confirm the mounting state.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a display panel production apparatus that facilitates visual confirmation of an attachment state by an operator.

In order to achieve the above object, a display panel production apparatus according to the present invention is a display panel production apparatus that attaches a member to an edge of a panel on the side facing the operator's face, and is attached on the panel. Based on the imaging means for imaging the member, the state determination means for determining whether or not the attachment state of the member is defective based on the image obtained by the imaging means, and the attachment state of the member by the state determination means When it is determined to be defective, the panel moving means for bringing the mounting position of the member whose mounting state is defective closer to the operator surface, the panel, the mounting position of the member on the panel, and the mounting position Display means for displaying a panel image indicating whether or not the mounting state of the member is defective, and the panel moving means has a defective mounting state of the member by the state determining means. If determined, the display panel production apparatus further moves the panel by moving the panel slidingly or rotating in a horizontal plane to bring the mounting position of a member having a poor mounting state closer to the operator surface. When the panel is slide-moved or rotated in a horizontal plane by the means, display control means is provided for causing the display means to display the panel image in the same direction as the slide-moved or rotated panel.

Thus, when it is determined that the mounting state is defective, the mounting location is brought closer to the operator's surface. Thereby, the distance from an operator to an attachment location becomes near. In general, there is no head or the like for attaching a member to the panel on the operator surface side, and it is brighter than the surface side to which the member is attached.
In addition, a panel image indicating the panel, the mounting location, and whether or not the mounting state is defective is displayed on the display unit in the same direction as the panel that has been slid or moved. As a result, the left and right and front side of the actual panel on the production line of the display panel production apparatus and the left and right and top and bottom relations of the panel image displayed on the display unit match. For this reason, the operator can easily associate the actual panel with the panel image, and can prevent the confirmation location from being mistaken when visually confirming the attachment location.

  Therefore, the operator can see the installation location in a nearby bright place, and the visual confirmation of the installation status can be facilitated.

In addition , the panel is rotated when it is determined that the attachment state of the member is defective. Thereby, an attachment location can be brought close to an operator. Therefore, it is possible to facilitate visual confirmation of the mounting state.

Further , when it is determined that the attachment state of the member is defective, the panel is slid toward the operator surface. The slide movement is a function provided in a general display panel production apparatus. By such a simple movement, the attachment location of the member on the panel can be brought closer to the operator, and the operator can more easily visually check the attachment location.

  The panel moving unit may rotate the panel and slide the panel toward the operator surface when the state determining unit determines that the mounting state of the member is defective.

  In this way, the panel is rotated and further slid. For example, if there is a space that can be slid further toward the operator's surface after being first rotated, the space can be reduced by sliding the panel toward the operator's surface. The same applies even if the procedure of rotation and slide movement is reversed, or the rotation and slide movement are simultaneous. Therefore, the attachment location of the member on the panel can be brought closer to the operator, and the operator can visually check the attachment location more easily.

Here, terms are defined.
“ACF” refers to an anisotropic conductive film, and in particular, tape-shaped ACF is referred to as ACF tape. When a predetermined pressure is applied in the thickness direction while the ACF is heated to a predetermined temperature, conductivity is generated in the thickness direction in the portion where the pressure is applied, and there are a plurality of places where the pressure is applied. Even in the case where the pressure is applied, the conductive portions are not generated in the places where the pressure is applied, that is, in the width direction and the length direction, and the insulating state can be maintained.

  “Panel” means a substrate for a display panel such as a liquid crystal display or a plasma display.

  The “attached state” refers to a state in which an ACF tape is attached on the panel and a state in which an electronic component is attached to the attached ACF tape.

  “Preliminary attachment” refers to attachment of an electronic component onto an ACF tape attached to a panel, and is also referred to as provisional pressure bonding.

  The “member” is attached to the panel and includes an ACF, an ACF tape, an electronic component, and the like.

  The “worker side” is one side of the display panel production apparatus on the side where the worker who works on the display panel production apparatus is present.

  According to the present invention, an operator can easily visually detect a determination error when automatically determining an ACF tape attachment failure or an electronic component attachment failure in display panel production. In addition, it is possible to suppress a decrease in production efficiency due to an error in automatic determination of attachment failure.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an overview of a display panel production system according to the present embodiment.

  As shown in the figure, the display panel production system includes a display panel production apparatus 100 and a panel information management apparatus 300. The display panel production apparatus 100 and the panel information management apparatus 300 are connected by a communication line 250.

  The display panel production apparatus 100 attaches the ACF tape 201 from which the base tape has been peeled off to two consecutive peripheral edges of the panel 200 shown in FIG. 2, and attaches a plurality of electronic components 202 on the ACF tape 201. This is a device for producing a display panel by crimping so that each of the parts 202 is electrically connected. Here, as a specific example of the panel 200, a glass substrate for a flat panel display can be cited.

  Such a display panel production apparatus 100 includes a tape attachment portion 101 for attaching the ACF tape 201 to the panel 200, a preliminary attachment portion 102 for attaching the electronic component 202 on the ACF tape 201, and the ACF tape 201 and the electronic component 202. A horizontal main press-bonding portion 103 and a vertical main press-bonding portion 104 that are made conductive by being pressed are provided. The direction in which the tape attachment portion 101, the preliminary attachment portion 102, the horizontal main crimping portion 103 and the vertical main crimping portion 104 are arranged is defined as the X direction, the depth direction thereof is defined as the Y direction, and the upward direction is defined as the Z direction. The θ direction indicates the direction of rotation in the XY plane.

  First, the tape attachment portion 101 is a portion where the ACF tape 201 is attached on the panel 200, and includes a unique information recognition camera 121, a table 123a, a tape attachment head 111, and an ACF tape holding portion 125.

  The unique information recognition camera 121 is a camera that recognizes unique information of each panel indicated by the two-dimensional barcode by reading a two-dimensional barcode (QR code (registered trademark)) attached on the panel 200. .

  Here, the two-dimensional barcode is an example of a unique information holding unit that is attached to the panel and holds information unique to the panel. The two-dimensional barcode only needs to be attached to the panel. For example, the two-dimensional barcode is printed on the panel surface, or a label on which the two-dimensional barcode is printed is attached.

  The unique information recognition camera 121 is an example of unique information recognition means for recognizing unique information of such a panel.

  The table 123a conveys the panel placed thereon. Further, the table 123a can slide the panel in the Y direction and rotate it in the θ direction for adjusting the position of the panel.

  The ACF tape holding unit 125 holds a reel around which the ACF tape 201 is wound, and feeds out the ACF tape 201 by a usage amount.

  The tape attachment head 111 is a head for attaching the ACF tape 201 sent out from the ACF tape holding portion 125 to each conduction portion of the panel. The tape attachment head 111 attaches the ACF tape 201 in the lateral direction of the panel 200 on the back surface facing the operator surface.

Here, the ACF tape is an example of a “member” attached to the panel.
Next, the preliminary attachment portion 102 is a portion for attaching the electronic component 202 on the ACF tape 201 attached to the panel 200, and includes a component attachment head 112, a state recognition camera 115, a table 123b, and a component reel 126. Prepare.

  The component mounting head 112 sucks the electronic component 202 supplied from the component reel 126 holding the electronic component 202 and conveys the electronic component to a predetermined mounting location on the mounted ACF tape 201. Install. The component mounting head 112 mounts an electronic component in the lateral direction of the panel 200 on the back surface facing the operator surface.

Here, the electronic component is an example of a “member” attached to the panel.
The state recognition camera 115 includes a camera that recognizes the attachment state of the ACF tape and the electronic component, and outputs an image indicating the attachment state. That is, the state recognition camera 115 is an example of an imaging unit that images a member attached on the panel 200.

  Similarly to the table 123a, the table 123b conveys the panel, slides the panel in the Y direction, and rotates it in the θ direction for adjusting the position of the panel. In addition to movement and rotation for adjustment, the table 123b slides the panel in the Y direction and rotates in the θ direction in order to bring the mounting position of the member on the panel in a poor mounting state closer to the operator's surface. Let

  The display unit 131 is a monitor or the like provided at a position where an operator on the operator side can contrast with the panel 200 on the table 123b. The display unit 131 shows the panel 200 on the table 123b of the preliminary attachment unit 102, the attachment location of the member at the panel 200, and whether or not the attachment state at the attachment location is defective. An image is displayed. Whether or not the mounting state displayed on the panel image is defective corresponds to a result recognized or judged in the display panel production system.

  The input unit 132 is a part for inputting the confirmation result after the operator visually confirms the mounting state of the panel, and is, for example, a button, a touch panel provided in the display unit 131, or the like. Thereby, the operator corrects a determination mistake in the display panel production system.

  Here, with reference to FIG. 3, an example of an operation performed on the panel 200 in the preliminary attachment unit 102 and a display on the display unit 131 will be described.

  FIG. 3 is a diagram illustrating a rotation executed on the panel 200 in the preliminary attachment unit 102 and a display example of the display unit 131. FIG. 3 includes an upper view before the panel 200 is rotated and a lower view after the panel 200 is rotated.

  The upper diagram of FIG. 3 shows a panel 200a that has only been transported in the X direction from the tape mounting portion 101, and a display portion 131 when displaying it. As shown in the figure, the right side of the ACF tape 202a attached in the third horizontal direction from the upper left of the panel 200a is bent. Bending is an example of poor attachment of ACF tape.

  The display unit 131 shows a panel image 400a in the same direction as the panel 200a on the table 123b. The panel image 400a includes an attachment image 401 in which each member attached to the panel 200a is associated with each attachment location.

  The third attachment image 401a from the upper left corresponds to a member having a bad attachment state. The attachment image 401a indicates that the attachment state at the attachment portion on the corresponding panel 200a is poor by a display different from the attachment image 401 in which the attachment state is normal. In the present embodiment, the attachment image corresponding to the normal attachment state is white, and the attachment image corresponding to the defective attachment state flashes black.

  Next, the lower part of FIG. 3 shows the rotated panel 200a and the display unit 131 for displaying it.

  The panel 200a shown in the lower figure shows a state in which the panel 200a shown in the upper figure is rotated 180 degrees.

  Thus, by rotating the panel 200a, the ACF tape 201a having a poor mounting state on the panel 200a becomes closer to the operator. In addition, since there is no component mounting head 112 for mounting electronic components on the panel 200a or a device for operating the panel 200a on the operator side of the display panel production apparatus, light hits the mounting location after rotation. It is easy and brighter than the surface where the member is attached. Therefore, the operator can see the installation location in a nearby bright place, and the visual confirmation of the installation status can be facilitated.

  In addition, the display unit 131 shown in the following figure displays a panel image 400b in the same direction as the panel 200a. In the panel image 400a in the upper diagram, the attachment image 401a indicating the defective state is the third from the upper left, whereas in the panel image 400b in the lower diagram, the attachment image 401a indicating the defective state is the third from the lower right.

  As described above, the panel images 400a and 400b are images showing a panel in the same direction as the panel 200a on the table 123b. Therefore, the worker can easily associate the attachment location on the panel 200a with the attachment images on the panel images 400a and 400b. Therefore, the operator can easily confirm whether there is any mistake in recognition or determination that the mounting state in the display panel production system is defective. In particular, when the panel 200a is rotated, making the orientation of the panel image 400b the same as that of the panel 200a is effective in preventing an operator's confirmation error.

From here, it returns to description of FIG.
Both the horizontal main crimping portion 103 and the vertical main crimping portion 104 are portions that electrically connect the terminals provided on the panel 200 and the electronic component 202 by crimping the ACF tape 201 and the electronic component 202.

  The horizontal book crimping part 103 is a part that crimps the ACF tape 201 attached in the horizontal direction of the panel 200 and the electronic component 202 so as to conduct, and includes a horizontal book crimping head 113 and a table 123c.

  The horizontal book pressing head 113 is a head that presses the ACF tape 201 and the electronic component 202 attached in the horizontal direction of the panel 200.

  Similarly to the table 123a, the table 123c moves and rotates the panel 200 for position adjustment.

  Further, the longitudinal book crimping section 104 is a part that crimps the ACF tape 201 attached in the longitudinal direction of the panel 200 and the electronic component 202 so as to conduct, and includes a longitudinal book crimping head 114 and a table 123d. .

  The longitudinal book crimping head 114 is a head that presses the ACF tape 201 and the electronic component 202 that are attached in the longitudinal direction of the panel 200.

  Similarly to the table 123a, the table 123d moves and rotates the panel 200 for position adjustment. The table 123d rotates the panel in the θ direction in order to perform main pressure bonding in the vertical direction of the panel.

  Next, the panel information management apparatus 300 is an apparatus that manages information related to the panel 200. The panel information management device 300 is realized by a computer, for example.

  The communication line 250 is a line that transmits information between the display panel production apparatus 100 and the panel information management apparatus 300. The display panel production apparatus 100 and the panel information management apparatus 300 may transmit information to each other wirelessly.

  FIG. 4 is a block diagram illustrating a configuration of each of the display panel production apparatus 100 and the panel information management apparatus 300 that manages panel information.

  In addition to the apparatus configuration shown in FIG. 1, the display panel production apparatus 100 is controlled by a control unit 150 implemented by a computer that executes a software program, the control unit 150, and provides information to the control unit 130. The mechanism part 120 is provided.

First, the display panel production apparatus 100 will be described.
About each part with which the mechanism part 120 is provided, the same referential mark is attached | subjected to the site | part same as each part shown in FIG. Since these portions have already been described, description thereof is omitted here.

  The control unit 150 is a part that transmits and receives information to and from the mechanism unit 120 and the panel information management device 300 and controls the mechanism unit. The model determination unit 151, the state determination unit 152, the table control unit 153, and the display A control unit 154, an individual information generation unit 155, and a head control unit 156 are provided.

  The model determination unit 151 acquires the unique information from the unique information recognition camera 121 and determines the model of the panel based on the unique information.

  The state determination unit 152 acquires image information indicating the attachment state of the member including the ACF tape and the electronic component from the state recognition camera 115, and at least one of the attachment state of the ACF tape and the attachment state of the electronic component is defective. Determine whether or not.

  The table control unit 153 controls the rotation and movement of the tables 123a to 123d. The table control unit 153 and the table 123b are panel moving means for bringing the mounting position of a member having a poor mounting state closer to the operator's surface when the state determination unit 152 determines that the mounting state of the member is defective. It is an example.

  The display control unit 154 is a control unit that causes the display unit 131 to display a panel image, and causes the display unit 131 to display a panel image in the same direction as the panel on the table 123b. That is, when the panel 200 is rotated by the table control unit 153 and the table 123b, a panel image in the same direction as the rotated panel 200 is displayed on the display unit 131.

  The individual information generation unit 155 generates individual information indicating an attachment state for each attachment location on the panel 200 and transmits the generated individual information to the panel information management apparatus 300.

  The head controller 156 controls the movement of each of the heads 111 to 114 in the X direction and the Z direction so that the processing by each of the heads 111 to 114 is executed at the correct position on the panel.

  Further, the head control unit 156 acquires the individual information from the individual information generation unit 155 and, based on the acquired individual information, the main book crimping head so that the member at the mounting location where the mounting state is normal is finally crimped. 113 and the vertical book crimping head 114 are controlled.

  As a result, a member having a poor mounting state is not finally bonded. Therefore, it is possible to easily remove the ACF tape and the electronic component that are in a bad mounting state. Therefore, it becomes possible to facilitate the repair of the panel 200 including a defective mounting state.

Next, the panel information management apparatus 300 will be described.
The panel information management device 300 is a device that manages panel information that is information relating to a panel, and includes a panel information storage unit 301, a panel information transmission unit 304, and an individual information storage unit 305.

  The panel information storage unit 301 is a storage medium that stores panel information that is information related to the panel. The panel information includes individual information 302 that is information on individual panels and model information 303 that is information for each type of panel.

A specific example of the panel information will be described with reference to FIGS.
FIG. 5 is a diagram illustrating an example of the individual information 302.

  The individual information 302 shown in the figure includes information “ID” that is information for identifying a panel individual, “model” that indicates the type of the panel, and “attachment state” of a member that is attached to the panel. including. The “attachment state” is associated with “position ID” for identifying the attachment location on the panel and “surface” indicating the attachment surface to which each attachment location belongs.

The individual information 302a shown in FIG. 5 shows an example of the individual information of the panel 200a shown in FIG.
The first individual information 302a shows an example in which the “ID” of the panel 200a is “0001” and the “model” is “A01”.

  “Position ID” is assigned from 1 to 6 from the upper left side to the right side of the first surface, which is the horizontal direction, for each mounting position of the panel 200a as viewed in the direction of panel transportation as shown in FIG. Furthermore, it is a number given from 7 to 10 from the upper right to the lower side of the second surface which is the vertical direction.

  For example, the first individual information 302a includes information indicating that the attachment location whose “position ID” is “3” belongs to the “1” plane and the attachment state is “NG”. Here, the attachment state “NG” indicates that the attachment state is defective.

  Further, for example, the first individual information 302a includes information indicating that the attachment location whose “position ID” is “7” belongs to the “2nd” surface and the attachment state is “OK”. Here, the attachment state “OK” indicates that the attachment state is normal, that is, not defective.

  Further, the second individual information 302b shown in FIG. 5 is an example of the individual information of the panel whose “ID” is “0010”. The third individual information 302b is an example of the individual information of the panel whose “ID” is “0011”.

  The panels indicated by the second individual information 302b and the third individual information 302b are all in an “unattached” state, indicating that the member has not yet been attached. The panel indicated by the second individual information 302b has “model” “A01”, the panel indicated by the third individual information 302c has “model” “B01”, and the models of the panels are different. In addition, the panel indicated by the second individual information 302b has the first “1” surface and the second “2” surface, and the panel indicated by the third individual information 302c has only the first “1” surface. Yes, each panel has a different mounting surface.

  By holding such individual information, it is possible to manage the state of the panel that has been produced by the display panel production apparatus 100. Further, when the display panel production apparatus 100 can automatically execute the attachment of the ACF tape and the electronic component for repair, it is possible to acquire a portion on the panel that needs repair by referring to the individual information.

FIG. 6 is a diagram illustrating an example of the model information 303.
The model information 303 includes a “model” for identifying the model, a “size” indicating the panel size of the model, and an “attachment position” for specifying a specific position for attaching the member.

  For example, the first model information 303a includes information indicating that the “size” is “46 inches” for the panel whose “model” is “A01”. In addition, with respect to the “attachment position”, there are attachment points at intervals of “L1” on the “1” plane with “(X1, Y1)” as a reference, and “(X2, Y2)” as a reference on the “2”. Information indicating that there is an attachment location at an interval of “L2” is included.

  The second model information 303b includes information indicating that the “size” is “17 inches” for the panel whose “model” is “B01”. In addition, the “attachment position” includes information indicating that there are attachment places on the first “1” plane at intervals of “L1” with “(X1, Y1)” as a reference.

  By referring to the model information 303, the panel size can be determined. Further, at the time of production of the display panel, the display panel production apparatus 100 can determine at which position the ACF tape is attached, the electronic component is attached, and pressure bonding is performed.

  In addition, the attachment position should just be able to identify the specific position which attaches a member, and the information which shows the coordinate of each attachment location may be contained.

FIG. 7 is a flowchart showing processing executed by the display panel production apparatus 100.
The unique information recognition camera 121 recognizes unique information shown on the panel 200 (S1).

  The model determination unit 151 acquires the unique information from the unique information recognition camera 121 and transmits it to the panel information management apparatus 300 (S2).

  The model determination unit 151 acquires panel information corresponding to the unique information from the panel information management apparatus 300 (S3).

  Here, the panel information acquired by the model determination unit 151 will be described with reference to processing in the panel information management apparatus 300 that reads the panel information.

  FIG. 8 is a diagram showing a flowchart of the reading process executed in the panel information management apparatus 300.

  The panel information transmission unit 304 acquires the unique information transmitted in the unique information transmission process (S2) (S31).

  The panel information transmitting unit 304 reads the “ID” individual information 302 corresponding to the unique information, and reads the “model” model information 303 included in the individual information 302 (S32).

  The panel information transmission unit 304 transmits the individual information 302 and the model information 303 thus read out as panel information (S33).

  Here, in the case of the panel 200 to which the ACF tape 201 and the electronic component 202 are not attached, the “attached state” included in the panel information is “not yet” as described above.

From here, it returns to description of FIG.
The model determination unit 151 acquires panel information from the panel information management apparatus 300, refers to the “model” included in the panel information, and determines the model corresponding to the panel 200 (S4).

  The state determination unit 152 acquires panel information from the model determination unit 151, refers to the “attachment position” included in the panel information, and causes the state recognition camera 115 to recognize the attachment state of the member attached to each attachment location. (S5).

  The state determination unit 152 acquires image information indicating the attachment state from the state recognition camera 115 that has recognized the attachment state, determines the attachment state at each attachment point, and indicates defective portion information indicating a portion where the attachment state is defective. Is generated (S6).

  In such state determination processing (S6), for example, the normal image information is acquired from a storage unit (not shown) that stores normal image information indicating the correct attachment state, and the image information and normal image acquired from the state recognition camera 115 are acquired. This can be realized by comparing the information and determining whether or not the index indicating the difference obtained as a result of the comparison is equal to or less than a threshold value.

  When the attachment state includes a defect (Yes in S6), the table control unit 153 acquires panel information from the state determination unit 152, and the panel size of the panel 200 based on the “size” included in the acquired panel information. It is determined whether or not is greater than a threshold value (S7). In this embodiment, the threshold value is 21 inches.

  When it is determined that the panel size is equal to or smaller than the threshold (No in S7), the table control unit 153 slides the table 123b (S8).

  The display control unit 154 acquires panel information from the table control unit 153, and generates a panel image including an attachment image based on the acquired panel information. The display control unit 154 further acquires defective part information indicating the attachment part determined to be defective in the state determination process (S6), and displays panel information in which the defective part is associated with the attachment image on the display unit 131. (S9).

  The individual information generation unit 155 accepts input by an operator for correcting a determination error in the state determination process (S6), corrects the defective part information, and holds the corrected defective part information. (S10). For example, the operator inputs an attachment image having a determination error from the input unit 132 realized by the touch panel, and sets the correct attachment state of the attachment portion corresponding to the attachment image as an “NG” button as the input unit 132 or “OK”. Enter by pressing the "" button.

  The individual information generation unit 155 determines whether or not an instruction notifying completion of confirmation of the attachment state has been received (S11). In the present embodiment, the “OK” button as the input unit 132 is continuously pressed twice to notify the end of the attachment state confirmation.

If the end instruction is not accepted (no in S11), the input acceptance process (S10) is continued.
When an end instruction is received (Yes in S11), the individual information generation unit 155 generates individual information including information indicating an attachment location where the attachment state is defective based on the failure location information held by itself. (S12).

  The individual information generation unit 155 transmits the generated individual information (S13). The individual information includes at least information for identifying the panel, information indicating each attachment location, and information indicating the attachment state at each attachment location.

Here, a process in the panel information management apparatus 300 that has received the individual information will be described.
FIG. 9 is a diagram illustrating a flowchart of storage processing executed in the panel information management apparatus 300.

The individual information storage unit 305 acquires individual information (S41).
The individual information storage unit 305 stores the acquired individual information in the panel information storage unit 301 (S42), and ends the process.

From here, it returns to description of FIG.
The table control unit 153 acquires the individual information from the individual information generation unit 155, moves the panel 200 based on the acquired individual information (S14), and ends the process.

  The above is the processing in the case where there is a defect in the pasting state for a small panel. A specific example of the movement of the panel 200 and a panel image displayed on the display unit 131 and a specific example of the individual information will be described with reference to the drawings.

  FIG. 10 is a diagram illustrating an example of a panel image on the display unit 131 corresponding to the state before and after the movement when the small panel is slid.

  FIG. 10 includes an upper view and a lower view. The upper diagram shows an example of the panel state and panel image before the panel 200b slides. The lower figure shows an example of the panel state and panel image after the panel 200b slides.

  The panel 200b shown in the figure is attached by being detached from the electronic component 202b which is the first attachment location from the upper left (hereinafter referred to as the attachment location where the “position ID” is “1”). The displacement of the position where the electronic component is attached is an example of defective attachment of the electronic component. Therefore, an affirmative determination is made in the state determination process (S6) (Yes in S6), and the process proceeds to the size determination process (S7).

  The panel 200b shown in this drawing is an example in which “model” is “B01”. The panel size of this model is “17 inches” as shown in FIG. 6, which is smaller than the threshold value of 21 inches. Therefore, a negative determination is made in the size determination process (No in S7), and the process proceeds to the slide movement process (S8).

  By the slide movement process (S8), the location of the panel 200b in the display panel production apparatus 100 is changed as shown in the upper drawing to the lower drawing in FIG. That is, the panel 200b approaches the operator's surface that is the operator's surface in the display panel production apparatus 100. The panel 200b after the slide movement is separated from the operator surface by a distance corresponding to the length of the panel in the vertical direction, but since the size of the panel is small, the operator can visually confirm the attachment location.

  Further, in the slide movement, the inertia force accompanying the slide movement applied to the attached member is small, and even if the member is moved quickly, the attachment position of the attached member does not shift. Therefore, since the moving speed can be increased, it is possible to reduce the time required to bring the defective attachment location closer to the operator.

  Further, the panel information 400c shown in FIG. 10 indicates that the attachment location that is determined to be defective by the display panel production apparatus 100 is the attachment location of “position ID” “1” in the attachment image 401c. Indicated by flashing. The panel information 400c is the same before and after the panel slide movement.

  In this way, the operator can determine the positional relationship between the mounting location determined to be defective by the display panel production apparatus 100 based on the panel image in the same direction as the panel 200b and the actual mounting status of the mounting location. It can be easily recognized. Therefore, visual confirmation can be facilitated, and errors in visual confirmation by the operator can be reduced.

Next, FIG. 11 is a diagram illustrating an example of individual information corresponding to the small panel 200b.
The individual information 302d shown in the figure corresponds to the small panel 200b.

  The “ID” of the individual information 302d is information for identifying the panel, and is “0002”. The individual information 302d includes that the “attachment state” at the attachment location where the “position ID” is “1” is “NG”.

From here, it returns to description of FIG.
When it is determined that the panel size is larger than the threshold value (Yes in S7), the following process is repeated for the number of surfaces including the defective attachment location (S15).

The table control unit 153 rotates the table 123b (S16).
The display control unit 154 acquires panel information from the table control unit 153, and generates a panel image including an attachment image based on the acquired panel information. The display control unit 154 further acquires defective part information indicating the attachment part determined to be defective in the state determination process (S6), and displays panel information in which the defective part is associated with the attachment image on the display unit 131. (S9). At this time, the display control unit 154 causes the display unit 131 to display a panel image in the same direction as the panel 200 rotated in the rotation process (S16) (S9).

  The individual information generation unit 155 executes input reception processing (S18). Since this is the same as the input reception process (S10), a detailed description thereof is omitted here.

  The individual information generation unit 155 determines whether or not an instruction for notifying the end of the attachment state confirmation has been received (S19). Since this is the same as the end instruction reception process (S11), a detailed description thereof is omitted here.

If the end instruction is not accepted (no in S19), the input acceptance process (S18) is continued.
When the end instruction is received (Yes in S19), the individual information generation unit 155 repeats the processes from the rotation process (S16) to the number of defective faces.

  When the processing for the number of defective surfaces is completed, the individual information generation unit 155 generates individual information including information indicating the attachment location where the attachment state is defective based on the failure location information held by itself ( S12).

  Subsequently, an individual information transmission process (S13) and a panel movement process (S14) are executed, and the process ends. Since the individual information transmission process (S13) and the panel movement process (S14) have already been described, a detailed description thereof is omitted here.

  The above is a process in the case where there is a defect in a sticking state with respect to a large panel. A specific example of the rotation of the panel 200 and a panel image displayed on the display unit 131 and a specific example of individual information will be described with reference to the drawings.

  FIG. 12 is a diagram illustrating an example of a state before and after rotation when a large panel is rotated and an example of a panel image on the display unit 131 corresponding to each state.

  FIG. 12 includes an upper view, a middle view, and a lower view. The upper figure shows an example of the state of the panel and the panel image before the panel 200c rotates. The middle diagram shows an example of a panel state and a panel image after the panel 200c is rotated 90 degrees. The figure below shows an example of the state of the panel and the panel image after the panel 200b is further rotated 90 degrees, that is, 180 degrees. The panel 200c shown in this figure is an example in which “model” is “A01”.

  As shown in the figure, the ACF tape 201c at the third attachment position from the upper left of the panel 200c (hereinafter referred to as “attachment position where“ position ID ”is“ 3 ”) is not normally attached. In addition, one side of the ACF tape 201d at the third attachment position from the upper right (hereinafter referred to as “attachment place where“ position ID ”is“ 9 ”) is bent and not correctly attached.

  Therefore, an affirmative determination is made in the state determination process (S6) (Yes in S6), and the process proceeds to the size determination process (S7).

  The panel 200c shown in this drawing is an example in which “model” is “A01”. The panel size of this model is “46 inches” as shown in FIG. 6, which is larger than the threshold value of 21 inches. Therefore, an affirmative determination is made in the size determination process (Yes in S7), and the process proceeds to loop A (S15).

  As shown in the panel image 400d in the upper diagram of FIG. 12, there are three places that are judged to be in a bad mounting state by the state judging unit 152. The first is an attachment image 401e corresponding to the attachment location where the “position ID” is “3”. The second is an attachment image 401f corresponding to the attachment location where the “position ID” is “4”. The third is an attachment image 401d corresponding to the attachment location where the “position ID” is “9”.

  That is, the attachment location with the “position ID” of “4” is normally attached on the actual panel 200c, but the attachment image 401f of the panel image 400d indicates that the attachment state is abnormal. That is, the state determination unit 152 makes a determination error.

  As described above, the surface to which the attachment location determined to be abnormal by the state determination unit 152 belongs to the first location where the “position ID” belonging to the first surface is “3” and “4”. There are two attachment positions, “position ID” belonging to the surface and “9”. Therefore, the process in the loop A (S15) is repeated twice.

  The middle diagram shows an example of a panel state and a panel image on which the process in the first loop A (S15) is executed. The panel image 400e is in the same direction as the actual panel 200c shown on the left.

  The following figure shows an example of a panel state and panel image on which the process in the second loop A (S15) is executed. The panel image 400f is in the same direction as the actual panel 200c shown on the left. In the panel image 400f shown in the figure below, the operator has corrected the determination error of the attachment location 401f in the input reception process (S10).

  Thus, by making the orientation of the panel 200c and the panel image 400f the same, the operator has a defect in the third attachment location 201c from the right and has no defect in the fourth attachment location from the right. The correspondence relationship between the panel image 400f and the attachment image can be easily determined. Therefore, it can be easily determined that the attachment location 401f shown up to the middle figure is a determination error, and accurate correction becomes possible.

Next, FIG. 13 is a diagram illustrating an example of individual information corresponding to the large panel 200c.
The individual information 302e shown in the figure corresponds to the large panel 200c.

  “ID” of the individual information 302e is information for identifying a panel, and is “0003”. The individual information 302e includes that the “attachment state” between the attachment location with the “position ID” “3” and the attachment location with the “position ID” “9” is “NG”.

  In addition, the “attachment state” of the attachment location whose “position ID” is “4” was determined to be defective by the state determination unit 152, but since it was corrected by the operator, a correct result corresponding to the actual attachment state, that is, “ “OK”.

  In this way, whether or not a defect has occurred in production is checked by a camera, and further, the operator visually confirms. At this time, since the defective mounting location is brought close to the worker, the worker can easily confirm whether or not the mounting state is correctly determined.

  Further, the panel image of the display unit provided at a position where the operator can contrast with the actual panel is in the same direction as the actual panel. Therefore, the operator can easily determine the correspondence between the mounting location and the mounting image, and can accurately confirm that there is no determination error.

  In addition, when there is a determination error, it is possible to suppress the correction error by inputting and correcting the attachment location included in the panel image in the same direction as the actual panel on the touch panel.

  The display panel production apparatus according to the embodiment of the present invention has been described above, but the present invention is not limited to this embodiment.

  For example, in the embodiment, the unique information is indicated by a two-dimensional barcode, but may be held in an RF tag. In this case, the display panel production apparatus 100 includes a reader that acquires information from the RF panel. By providing a reader instead of the unique information recognition camera 121, the same production as in the embodiment can be realized.

  Further, for example, in the embodiment, the attachment failure of the ACF tape and the attachment failure of the electronic component are both treated as attachment failure without being distinguished from each other and included in the individual information 302. The individual information 302 may be included in the individual information 302 by distinguishing and processing whether it is a poor attachment or an electronic component attachment failure.

  Further, for example, in the embodiment, after the attachment of the ACF tape and the attachment of the electronic component is completed, the steps for the operator to confirm (from the state recognition process (S5) to the individual information transmission process (S13) in FIG. 7). However, it may be executed after the attachment of the ACF tape is completed and after the attachment of the electronic component is completed. Thereby, since it can control so that an electronic component may not be attached to the attachment location where the attachment state of an ACF tape is bad, it becomes possible to omit such a useless electronic component attachment process.

  Further, for example, in the embodiment, depending on the panel size, one of the slide movement and rotation is performed to bring the defective attachment location closer to the operator surface. However, the slide movement and rotation may be performed. .

  FIG. 14 is a diagram showing an example of a panel image on the display unit 131 corresponding to each state before and after sliding and rotating the panel.

  FIG. 14 includes an upper view and a lower view. The upper diagram shows an example of a panel state and a panel image before the panel 200b slides and rotates. The figure below shows an example of the state of the panel and the panel image after the panel 200b slides and rotates.

  As in the panel 200b shown in FIG. 10, the panel 200b shown in this figure is attached with the electronic component 202b at the attachment location where the “position ID” is “1” being shifted.

  The orientation of the panel image 400g shown in the following figure is the same as the orientation of the panel after movement including rotation.

  By sliding and rotating, the operator can visually check the actual panel mounting location at a closer location.

  Further, since the orientation of the panel 200b and the panel image 400g is the same, it is possible to easily confirm the operator's judgment error. Further, if there is a judgment error, the position is corrected without error. It becomes possible to do.

  Further, for example, in the embodiment, a plurality of types of display panels having different sizes are produced by one display panel production apparatus 100. However, the display panel production apparatus 100 produces one type of display panel or Different display panels of the same size may be produced.

  In this case, production panel information that can specify the size of the display panel such as the type of display panel to be produced may be registered in the display panel production apparatus 100 in advance. Further, the production panel information may be information indicating the size of the display panel to be produced in addition to the display panel model.

  In this case, the display panel production apparatus 100 includes a production panel storage unit that stores production panel information that can specify the size of the display panel, and is registered by updating the production panel information in the production panel storage unit. In addition, the model determination unit 151 determines the model by acquiring the production panel information in the production panel storage unit.

  Further, the panel size determination process (S7) shown in FIG. 7 may not be executed. That is, the table control unit 153 repeats the process from the rotation process (S15) to the end instruction acceptance determination (S19) for the number of defective surfaces (S15) or slide movement according to the registered display panel size. Only one of a series of processes from the process (S8) to the end instruction reception process (S11) is executed. Specifically, when the size of the display panel is larger than the threshold, the table control unit 153 repeats the rotation process (S15) to the end instruction acceptance determination (S19) only for the number of defective surfaces (S15). Execute. When the size of the display panel is equal to or smaller than the threshold value, a series of processes from the slide movement process (S8) to the end instruction reception process (S11) are executed.

  Thereby, the process in the display panel production apparatus 100 which produces the display panel of a fixed size can be reduced. Therefore, the processing load of the display panel production apparatus 100 can be reduced, and production efficiency can be increased.

  The present invention can be applied to a display panel production apparatus.
