Description

Visual zig apparatus for inspecting flat panel display}

The present invention relates to a visual jig device for inspecting a display panel. More specifically, the pin board having a probe pin can be moved up / down / front / back by one cylinder, and the jig angle is adjusted according to the operator's vision. A jig device for inspecting small and medium sized display panels can be provided.

In general, a flat panel display (hereinafter, referred to as a display panel) refers to an image display device that is thinner and lighter than a television or a computer monitor (Brown Tube). Such display panels typically include LCD, PDP, FED, ELD, etc., and the structure and manufacturing method thereof are slightly different for each type.

As an example, the structure of the TFT-LCD will be described as a lower glass substrate on which TFTs (thin film transistors) are formed, an upper glass substrate on which color filters are formed, and liquid crystals injected therebetween. Consists of. The TFT serves to transmit and control the electrical signal, and the liquid crystal controls the transmission of light by varying the molecular structure according to the applied voltage. The light so controlled passes through the color filter to produce the desired color and image.

In addition, the LCD manufacturing method is largely composed of a TFT process, a color filter process, a cell process, and a module process. In the TFT process, very similar to the semiconductor manufacturing process, deposition, photography, and etching are repeated to form and form TFTs (thin film transistors) on the lower glass substrate. In the color filter process, a color filter is formed on the upper glass substrate. In the cell process, an alignment layer is formed between the lower glass substrate and the upper glass substrate, and the spacers are dispersed and then bonded to each other. After the bonding, the liquid crystal is injected between the upper glass substrate and the lower glass substrate by using a capillary phenomenon, and then the injection hole is sealed. In the module process, various peripheral parts such as a polarizer and a backlight are attached to the flat plate.

On the other hand, the display panel is subjected to various electrical tests to check whether it normally operates before the module process after the cell process. That is, when various electrical signals are input while the probe pins are electrically connected to the pattern formed on the display panel, the display panel visually inspects whether the display panel properly displays. This visual inspection is a full inspection because the above-described display panel is assembled into a product immediately after modularization.

However, in the related art, the inspection of the display panel is performed manually by an operator, so that the time is very long. That is, in a state where the operator places the above-described display panel on a jig of a certain type, the inspection probe is electrically contacted with a predetermined pattern of the display panel and inspected so that it takes a long time and the inspection is not performed accurately.

In addition, recently, since the pitch of the input / output pattern formed on the display panel is gradually finer, it is very difficult for the operator to directly contact the probe pin with the pattern, and thus the inspection speed is further lowered.

Moreover, the force for bringing the probe pins into contact with the pattern of the display panel is different for each operator, and thus there is a problem that the glass substrate or the pattern of the display panel is broken in some cases.

The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to move the pin board having a probe pin with one cylinder up / down / before / back accurately to the display panel which can be in contact with the pattern of the display panel It is to provide a jig device for panel inspection.

Another object of the present invention is to provide a jig device for inspecting a display panel that can inspect the operation state of the display panel at the most appropriate angle by adjusting the angle of the display panel according to the operator's vision.

It is another object of the present invention to provide a jig device for inspecting a display panel that can prevent damage to a pattern or a glass substrate during inspection as well as accurate electrical contact by contacting a pattern of a flat panel display and a probe pin only with a predetermined force. It is.

First, referring to FIGS. 1,2 and 3, the jig 110 is provided with a jig plate 111 having a substantially rectangular or square shape, and the jig plate 111 has at least two rectangular seating grooves 112 formed therein. It is. In addition, a flange 113 having a predetermined length is formed inside the seating groove 112, so that only the edge region 117 of the display panel 116 is seated to prevent direct contact with the active region 118. In addition, a back light 115 is installed inside the jig 110 to illuminate the inspection image of the display panel 116 by providing illumination through the seating groove 112. The backlight 115 may be installed separately in the rear of each of the mounting grooves 112 or one may be installed in the form of providing illumination to each of the mounting grooves 112. In addition, the jig 110 has grooves 114 of a predetermined depth formed at both left and right sides of the seating groove 112, whereby an operator stably positions the display panel 116 in the seating groove 112. It is supposed to be possible. Here, a plurality of input and output patterns 119 are formed on an upper end of the display panel 116, and the display panel 116 is seated in the mounting groove 112 so as to face upward. .

Subsequently, referring to FIGS. 2, 3, and 4, the pin board 120 is positioned in front of and above the jig 110, which is in contact with the input / output pattern 119 of the display panel 116 to display the display. It serves to transfer various electrical input / output signals to the panel 116. Indeed, the pin board 120 is in electrical contact with the display panel 116, thereby performing a visual inspection of the display panel 116. Of course, the pin board 120, but is not shown is connected to a circuit board for generating and transmitting a variety of electrical signals. The pin board 120 is first located at the front and the top of the jig 110, the rear includes a board plate 121 having a plurality of probe pins 122. Of course, the probe pin 122 is an area in electrical contact with the input / output pattern 119 formed on the display panel 116. In addition, a support shaft 123 having a predetermined length is formed in the upper and lower lengths of the board plate 121, a spring 124 is coupled to the support shaft 123, and the support shaft ( The cam 125 is formed at the upper end of the 123. In addition, the upper surface of the cam 125 is formed with a flat surface (125a) from the front, the rear of the flat surface (125a) is formed with an inclined surface (125b) inclined at an angle downward. Furthermore, a roller 126 is further provided in contact with the flat surface 125a or the inclined surface 125b of the cam 125 to guide the cam 125 downwardly and rearwardly or upwardly and forwardly. . Of course, this roller 126 is fixed by the bracket 127, the bracket 127 is also coupled to the rear base plate 145. Of course, the roller 126 is in contact with the flat surface 125a and the inclined surface 125b of the cam 125 to be rotatable in a predetermined direction.

The board cylinder 130 is coupled to the rear of the pin board 120 so that the pin board 120 is in contact with the input / output pattern 119 of the display panel 116. That is, the board cylinder 130 is composed of a body 131 and the rod 132, the rod 132 is coupled to the support plate 123 inside the board plate 121 or board plate 121 It is. Therefore, after the display panel 116 is seated on the jig 110 and the board cylinder 130 is operated, the rod 132 first pulls the board plate 121 backward. Then, the cam 125 installed on the board plate 121 moves downward and backward while compressing the spring 124 of the support shaft 123. That is, since the inclined surface 125b and the flat surface 125a formed on the cam 125 are sequentially moved in contact with the roller 126, the pin board 120 is moved as a whole. Therefore, when the inclined surface 125b formed on the cam 125 moves backward while contacting the roller 126, the pin board 120 moves simultaneously to the bottom and rear as a whole, and the flat surface 125a formed on the cam 125 ) Moves to the rear while in contact with the roller 126, the pin board 120 is moved to the rear as a whole. Of course, due to the movement of the pin board 120, a plurality of probe pins 122 formed at the rear of the board plate 121 is electrically connected to the input / output pattern 119 of the display panel 116 seated on the jig 110. Is connected.

The jig cylinder 140 serves to adjust the jig 110 at an angle appropriate to the viewing angle of the inspector. In general, the display panel 116 is difficult to see when the viewing angle with the user is distorted. Therefore, the display panel 116 needs to be adjusted. Moreover, since all the keys are different for each examiner and therefore all viewing angles are different, it is necessary to adjust the viewing angle of the display panel 116 according to the inspector. Before describing the jig cylinder 140, the structure of the base plate 145 will be described in more detail. In particular, as shown in FIG. 5, the base plate 145 is further provided with a rotating shaft 148 at a rear center thereof, and a bracket 143 is provided at an upper portion thereof. In addition, the rear plate 146 is further installed at the rear of the base plate 145 while being inclined at a predetermined angle, and the bracket 144 is further installed at the rear plate 146. Meanwhile, a cylinder for jig 140 is mounted between the bracket 143 of the base plate 145 and the bracket 144 of the rear plate 146. That is, the jig cylinder 140 is composed of a first body 141a and a second body 142a, and the first body 141a is formed with a first rod 141b and the front end of the base plate ( 145 is coupled to the bracket 143. In addition, the rear end is coupled to the bracket 144 of the rear plate 146 with the second rod 142b formed on the second body 142a. Therefore, when the jig cylinder 140 is operated, the base plate 145 provided with the jig 110, that is, the jig 110 is installed at an angle of about 45 ° to 75 ° with respect to the rotation axis 148, and the upper end thereof forward. Will rotate. In other words, the viewing angle of the display panel 116 seated on the jig 110 may be adjusted to match the viewing angle of the inspector. In addition, the jig cylinder 140 is capable of operating in multiple stages. That is, only the first body 141a and the first rod 141b operate, only the second body 142a and the second rod 142b operate, or the first and second bodies 141a and 142a and the first rod. By operating the two rods 141b and 142b simultaneously, the rotation angle of the base plate 145 can be adjusted. In the drawing, reference numeral 147 serves as a side plate so that various structures behind the base plate 145 are not visible from the outside when the base plate 145 rotates.

The pole 150 is located at the front of the jig 110 and the pin board 120 at the same time, and serves to ensure that various inspection images of the display panel 116 are properly displayed to the inspector. That is, guide rails 151 having a predetermined length are formed in upper and lower directions on both sides of the jig 110 and the poles 150 having a substantially rectangular shape are coupled to the guide rails 151. It is. The pawl 150 is manually lowered by an operator during the inspection of the display panel 116 and is located in front of the display panel 116. Thus, the inspection image of the display panel 116 is not displayed to the inspector until the pole 150 is positioned in front of the display panel 116.

Finally, the ionizer 160 serves to remove static electricity that may occur during the inspection of the display panel 116. (See FIG. 1) The ionizer 160 is the base plate 145. It is mounted on one side of which causes blowing of ions to remove static electricity toward the display panel 116 during inspection of the display panel 116.

By the above configuration, the visual jig device 100 for inspecting the display panel according to the present invention is operated as follows.

First, the inspector places the display panel 116 in the seating groove 112 provided in the jig 110. That is, while holding the left and right sides of the display panel 116, the hand is positioned in the groove 114 formed on both sides of the seating groove 112, so that the display panel 116 is stably positioned in the seating groove 112. Let's do it. Of course, at this time, only the edge region 117 of the display panel 116 contacts the flange 113 inside the seating groove 112, so that the active region 118 of the display panel 116 is not damaged. In addition, by turning on the backlight 115 provided inside the jig 110 while the display panel 116 is seated in the seating groove 112 of the jig 110, the backlight 115 is turned on the display panel. Allow 116 to be projected from behind.

Subsequently, the inspector operates the jig cylinder 140 so that the probe pins 122 of the pin board 120 electrically contact the input / output pattern 119 formed on the display panel 116. That is, before the first inspection of the display panel 116, the pin board 120 is located in front of the jig 110 and at the top. After the jig cylinder 140 is operated, the rod 132 coupled to the body 131 pulls the board plate 121 backward. Then, the cam 125 installed on the board plate 121 moves downward and backward while compressing the spring 124 of the support shaft 123. More specifically, the inclined surface 125b and the flat surface 125a formed on the cam 125 move while sequentially contacting the roller 126. Therefore, when the inclined surface 125b formed on the cam 125 moves backward while contacting the roller 126, the pin board 120 moves simultaneously to the bottom and rear as a whole, and the flat surface 125a formed on the cam 125 ) Moves to the rear while in contact with the roller 126, the pin board 120 is moved to the rear as a whole. Of course, due to the movement of the pin board 120, the plurality of probe pins 122 formed on the back of the board plate 121 is accurate to the input / output pattern 119 of the display panel 116 seated on the jig 110. Is quickly and electrically connected

The inspector then manually lowers the pole 150 such that the pole 150 is positioned in front of the jig 110, ie, the display panel 116. At this time, the pawl 150 is lowered along the guide rail 151 of a predetermined length formed in the longitudinal direction on both sides.

Meanwhile, the ionizer 160 formed on one side of the base plate 145 also operates during this operation. That is, ions are blown from the ionizer 160 to remove static electricity that may be generated during the inspection of the display panel 116.

By this operation, the inspector visually inspects various inspection images output through the display panel 116 through the pole 150. That is, the display panel 116 is visually inspected for the final operation before the display panel 116 is modularized or mounted on a product.

In addition, the present invention can operate the jig cylinder 140 to accurately position the display panel 116 at the viewing angle of the inspector as described above. The jig cylinder 140 is operated, and the angle of the base plate 145 on which the jig 110 is mounted is appropriately changed. That is, the base plate 145 in which the jig 110 is installed when the jig cylinder 140 is operated is rotated at an upper end thereof at an angle of about 45 to 75 ° about the rotation shaft 148. In addition, only the first body 141a and the first rod 141b constituting the jig cylinder 140 may be operated, or only the second body 142a and the second rod 142b may be operated, or the first and second bodies ( By operating the first and second rods 141a and 142a and the first and second rods 141b and 142b simultaneously, the rotation angle of the base plate 145 can be adjusted to an arbitrary angle.
