( 。 The contact unit 17G is in contact with the lead unit 25 of the circuit board 2G and applies a detection signal to the lead. For example, the contact unit m can be a detection board. The pcB, Fpc board or the like is defined. There is no limitation of the type of the detecting board, and the limiting condition is that the detecting lead 172 of the lead unit 25 contacting the board 2 can be formed on the detecting board. The π detecting lead 172 is disposed to face the lead unit 电路 of the circuit board 2 so that it can contact the lead unit 25. In the present exemplary embodiment, the lead unit 25 is illustrated as being formed on one of the lower surfaces of the circuit. However, the 'detection lead' may be formed on the lower surface of the contact unit in which the lead unit is formed on the surface of the upper surface of the circuit board. Referring to Fig. 1, Fig. 5, and Fig. 5, a detecting lead 172 capable of contacting the lead unit 25 of the printed circuit board 2 is placed on the upper surface of the contact unit (7). The inclined portion 174 may be formed at the end of the contact unit 17 () such that the board is not caught by the contact unit when the board is privately moved. According to an exemplary embodiment of the present invention, as shown in FIG. π, the contact early 170 may be configured as a detecting plate including a slanted portion ,4 which becomes toward the end of the contact unit 17〇 Thinner. Referring to FIG. 5C and FIG. 5, a unit 270 according to another exemplary embodiment of the present invention may be assembled into a detecting board including a rounded portion 274 by repairing the end of the & The circle is formed to form the rounded portion 274. The rounded portion 274 prevents the circuit board 20 from being caught by the contact when moving a circuit board. Referring again to FIGS. i through 3, the gas ejecting unit 14 is configured to secure the circuit board by ejecting a gas on the circuit board 20. "In detail, when an FPC board made of a flexible material is used as a circuit. When the board is 2 ,, when the ejection board is in use, the end of the board 20 may be curled. Therefore, when the gas is ejected onto the board 20, the board 20 can be easily fixed. The panel is moved toward the panel detecting device 1G, the circuit board 20 connected to the panel 经 is positioned on the illumination unit 150, and the lead unit 25 formed at the end of the circuit board 20 = is located under the contact block 12 (). On the other side of the circuit board 20 with respect to the illumination unit 15A. Here, the illumination unit 150 irradiates light onto the circuit board 2, so that the image recognition unit (10) can easily recognize the circuit board 2G. The gas ejecting unit 14 jets gas onto the circuit board 20 to fix the circuit board. The gas may be air. To prevent oxidation of the circuit board 20, nitrogen, an inert gas or the like may also be used. The spray unit 140 can spray the gas It is incident on any portion of the circuit board 20. Then, in order to effectively fix the circuit board 2, gas is preferably sprayed onto the lead unit 25 formed at the end of the circuit board 20. The gas injection unit 140 is required when needed. The gas can be simultaneously injected onto the circuit unit 25 and the illumination unit 15A to achieve a more efficient fixing of the circuit board 20. The position of the gas injection unit 14 is not limited, and the gas can be 嗔The firing unit 140 is disposed at any position of the fixed circuit board 2. The discharge pressure of the 122025.doc -11 - 200817699 gas from the gas injection unit 根据4〇 is adjusted according to the size and shape of the circuit board 20. When necessary, A plurality of gas jetting units can be used. Referring to Figures 6A and 6B, the gas jetting unit 14 has a nozzle having a circular cross section. The body jetting sheet having a circular cross section in the form of an angular angle I The heart () system is relatively easy to miniaturize, so it can pass through the 纟^/ :- complex system. In addition, it can be concentrated in the desired area ::: Ο

Q Referring to Figs. 7 and 7B, which illustrate a modified embodiment of the gas injection unit 14A of Figs. 6A and 6B, a gas having a slit cross section is formed as a gas injection unit 240. The gas ejecting unit 240, which is formed in the form of a nozzle having a slit-like cross section, forms a linear ejection pattern, and thus can pressurize a relatively large area of the board 2G to effectively fix the circuit board 20. In detail, in the case where the FPC board is used as the board 2, the gas ejecting unit 24 configured in the form of a slit-like jet nozzle is used to enable a gas to be ejected to the lead unit at the end of the board 20. The entire surface of the 25 is used to improve the fixed efficiency of the circuit board 20. The width of the gas ejecting unit 240 having a slit-like cross section may be the same as the width of the circuit board 2''. Alternatively, a plurality of gas ejecting units having a width smaller than the width of the board 2 can be used. Referring again to Figs. 1 through 3, in addition to the use of the gas ejecting unit 14, a negative pressure (vacuum pressure) may be used to fix the circuit board 20. When a panel is moved such that the circuit board 20 is placed on the lighting unit 15A, a suction portion 154 formed at the illumination unit 150 is evacuated to fix the circuit board 20 to the suction portion 154. Since the circuit board 2 has a large area with respect to the thickness, it is effective to fix the circuit board 20 by suction. The suction holes for fixing the circuit board 20 for evacuation are not necessarily formed in the illumination unit 15A. In some cases, the suction holes may be formed in a test plate 12 or may be formed separately. Depending on the type, material, etc. of the circuit board 20, the gas injection unit 140 and the suction portion 154 may be used in combination, or only one of them may be used. The positioning unit 110 aligns the leads of the lead unit 25 of the circuit board 20 with the detecting leads 172 of the contact unit 170 such that the leads of the lead unit 25 of the circuit board 20 contact the detecting leads 172 of the contact unit 170. The positioning unit 11 moves the detection lead 1 72 of the contact unit 1 70 according to the image information recognized by the image recognition unit 130, so that the detection lead i 72 contacts the lead of the lead unit 25 of the circuit board 2〇. Since the lead of the lead unit 25 of the board 2 and the detecting lead 172 of the contact unit 系 are in the form of a thin line pattern, there are: the lead of the lead unit 25 is precisely aligned with the detecting lead 172. The positioning unit 110 includes a detecting board 112 for placing the contact unit 170 and a

The leads of unit 25 are precisely aligned with the sense leads 172 of contact unit 17A. For this purpose, at least one of the first is accurate. The actuator 114 can move the circuit board 2 and the contact unit 17A such that the leads of the lead unit 25 can be aligned with the detection leads 172.

122025.doc -13 - The mobilization of the 200817699. That is, considering that the lead of the lead unit 25 and the detecting lead 2 are elongated in the i-direction and the backward direction, when the circuit board attached to a panel is moved to be placed on the detecting board 112, it may not be necessary in the forward direction. The leads of the lead unit 25 and the detection leads 172 are aligned in the backward direction. Thus, if necessary, the brother uses the lead for aligning the lead unit 25 forward and backward when needed.

And an actuator that detects the lead 172. The first actuator Π4 can be a stepping motor capable of controlling the lead of the lead unit 25 and detecting the position of the lead 〇 m in an accurate and relatively simple manner. However, it is possible to use a direct current motor, a hydraulic cylinder, a pneumatic cylinder or the like to control the lead of the lead unit 25 and the position of the detecting lead 172. The contact unit 170, which is responsible for applying the detection signal, according to the above-described exemplary embodiment, is moved relative to the circuit board 2''. However, the invention is not limited to the illustrative embodiments described above. That is, the circuit board 2 is movable relative to the contact unit 170. In order to achieve faster and more precise alignment, the circuit board 20 and the contact unit 17A can be moved simultaneously. The contact block 120 is pressed against one of the contact portions between the lead unit 25 and the detecting lead 172 so that a detection signal is accurately applied to the lead unit U. Referring to Fig. 3, the contact block 12 is located directly above the contact portion between the lead unit of the board 2 and the detecting lead 1 72 of the contact unit 170. When the lead of the lead unit 25 and the detecting lead 172 are aligned by the positioning unit 11A, the contact block 120 is moved downward by an operating cylinder 16〇 and pressurized to the contact portion between the lead unit 25 and the detecting lead 2, so that A detection signal is accurately applied to the lead unit 25. When the contact block 120 is pressed against the contact between the lead unit 25 and the detecting lead 172, the controller (not shown) applies a detection signal to a panel. When the contact block 120 is pressed against the contact portion between the lead unit 25 and the detecting lead m, the circuit board 2 and the contact unit 17A may be worn or damaged. To solve this problem, the contact block 120 may further include a buffer portion. The buffer portion 122 is retracted into the contact block 120 when the pressure applied by the contact block 120 to the contact portion between the lead unit 25 and the detecting lead 172 exceeds a predetermined pressure. An elastic body (e.g., a spring) having a predetermined tension can be inserted between the contact block 120 and the buffer portion 122 to absorb the impact on the circuit board 2 and the contact unit 170. A bumper made of a flexible and resilient material can be mounted at one end of the buffer portion 122 of the direct contact circuit board 20. As mentioned above, the illumination unit 150 is used to irradiate light onto the circuit board 2' to facilitate enhancing the recognition rate of the image recognition unit 130. In the present invention, the lamp 152 may be an LED or the like and irradiate light onto the lower surface of the circuit board 2''. When the FPC board is used as the circuit board 20, it is emitted from the illumination sheet (the light of the J element 150 is continuously transmitted through the circuit board 20, and thus the image recognition unit 130 can effectively recognize the pair of the lead unit 25 and the circuit board 20. Alignment mark 27 ° When the circuit board 20 is made of an opaque material, the illumination unit 15 can be placed over the circuit board 20 such that light is irradiated on the upper surface of the circuit board 20. The illumination unit 150 can use light. To enhance the image recognition rate, and at the same time serve as a suction portion for the fixed circuit board 20. Thus, in some exemplary embodiments of the invention, a suction portion and a lighting unit may be separately mounted.
