Description of the Invention: [Technical Field] The present invention relates to an inspection device and a method for a touch panel (touch screen) touch function, and more particularly to checking whether a touch sensing function of a touch panel product is Good, the result of the inspection is the equipment that passes or fails. [Prior Art] The following describes the traditional method concept of checking the touch panel touch sensing function using the device that checks the characteristics of the touch panel (touch sensing function). In the mass-produced touch panel, the process factor causes the defective product to be produced. Therefore, the touch sensing function of all the produced touch panels is checked to separate the defective products from the good products. The item to be checked first is whether the touch panel senses the touch; whether the touch position sensed by the first touch panel is correctly transmitted to the computer. The check uses the execution of the two items to detect defective products. An algorithm for checking the touch sensing function in the action area of the touch panel will be described below. First, decide to check the location of the touch sensing function. One of the two sides of the touch panel for inductive touch is called a touch sensing surface, and the other side is called a rear surface. The touch panel area that is touched in the touch sensing surface is called the motion area. In this case, the coordinates of all the positions where the touch sensing function is to be surely checked in the action area are set to (X-LY_)) to (Χη, γ_η). Next, decide on good and bad products. The method of determining whether the product is a good or a defective product will be described in detail below. 5 1332168 First of all, suppose that the perfect normal touch panel can accurately sense the touch, and accurately detect the coordinates of the touch position according to the theory, and the touch position estimated by the A-level normal touch panel is touched. The coordinate value of (X-), Y-1) is set to (ΧΑ_1ΥΑ_υ. Thus, the coordinate value of all positions of the theoretically good good inductive touch is set to (XA-LYA j) to (XA-n, YA-n).利用 Before using the touch sensing function of all touch panels to determine the _ classification, all mass production touch panels are listed as defective B. Secondly, check the touch and evaluate the touch position. The coordinate value of the panel position is set to (XB-LYB - D. Thus, the coordinate value of all positions on the touch panel to check the touch sensing is set to (χΒ ι, γΒ_)) to (ΧΒ-η, ΥΒ-η) Furthermore, the coordinate values (χΒι, ΥΒ-1) to (ΧΒ-η, ΥΒ-η) of the position actually sensed by the touch panel will be compared with the theoretically correct coordinate values (χΑ_丨, γΑ_ 〗) to (\ Eight _11, ¥winter 11) Comparison, the difference between the results of using the two positions is φ No greater than the allowable error to separate good and bad products. The actual operation of the touch sensing function is as follows: First, all the positions (Χ-^) to (χ_η, γ_η) to be checked by the touch panel are made by like a touch pen. When the device touches and evaluates the coordinates of the position touched by the touch panel, 座-], ΥΒ-]) to (XB_n, YB_n), the actual coordinate value to be evaluated when the theoretical normal product A is checked ( χΒιγΒ_ι) to (ΧΒ-η, ΥΒ-η) are compared with the coordinate value (XmA-i) to (χΑ η, γΑ η) 'When the comparison result is within the predetermined allowable error, the touch panel can be judged to be a normal good' When the comparison result is not within the predetermined permission (4), it can be judged that 6 r1332168 is broken as a defective product. The seventh picture is a photo of the traditional inspection device of the touch panel touch sensing function. In the conventional inspection device, the touch panel performing the touch sensing inspection is performed. The direction of the touch sensing surface is upward. In other words, the touch panel is placed on the bottom plate of the first inspection, so that the touch sensing surface of the touch panel is facing the touch pen disposed thereon. Next 'for The touch pen device that touches the sensing function is mechanically driven to an inspection position in the action area of the touch panel of the touch panel (χ-ι, γ-υ (first movement). Then, in the touch When the panel reaches and is set to the (x-m) coordinate inspection position, the pneumatic control or the electric motor is used to drive the mechanical control mode to drive the touch stone sub-pen, so that the touch pen touches the touch panel to touch the touch surface of the touch surface (first Second touch action. Next, according to the touch action of the touch pen, after the touch sensing function is surely checked, the touch panel can sense the touch action and calculate the coordinate value (ΧΒ-1, ΥΒ-1) Then, the first movement and the second touch motion are continuously repeated from the inspection position (\_1, 丫_1) to (乂_11, ¥_11) to calculate the coordinate value (XB n, YB n) 〇 In this case, the continuous movement can be expressed by a function of (touching the movement of the pen + contact of the touch pen) χ η (checking the number of predetermined positions of the touch sensing function). In this function, the individual coordinate values of the touch sensing function check position are (χβ-], υβ-ι) to (ΧΒ_η ΥΒ η). Next, by comparing all coordinate values, it is determined whether the checked touch surface 7 1332168 board is defective or good. In more details, the individual coordinate values of the inspection positions in which the touch sensing function is checked are (XB-n, YB-n) and the coordinate values of the theoretical normal touch panel (χΑ_], ΥΑ-1) to ( ΧΑ_η, ΥΑ·η) are compared, and when the comparison result is within the predetermined allowable error, it may be determined that the touch panel to be inspected is good, or when the comparison result is not within the allowable error, the touch panel can be determined. However, conventional inspection equipment has the disadvantage of being inspected for too long. For the evaluation of the continuous coordinate value from the inspection position (^7 to the inspection position (Χ-η'Υ-η) using the conventional inspection equipment, as described above, the operation must be performed (touch pen movement + touch pen contact) Χn times, so the total operating time is 2η ° ... From the time point of view, because the device moves to touch the pen I and touch, etc., it must be repeated from the first inspection position to the last inspection position, so that the required operation time is ( Touch pen movement time + touch pen contact time, η. For example, in the case of using the traditional inspection device, in order to evaluate the time required to check the touch function of a single 7-inch touch panel, if the touch is 7 inches In the action area of the panel, set the number of inspection positions to 12 (the time when the ten-touch pen movement is set to] seconds, and the day when the touch pen moves to each other; 'Check the total temple required for the touch panel to touch the sensing function. Therefore, the inventors decided that in the conventional inspection apparatus, first, the movement of the device that fixes the touch pen to many inspection positions must be changed to 8 1332168. Second, touch The operation method of the pen must be improved. Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide an apparatus for inspecting a touch panel touch sensing function and a method thereof, wherein the operation mode of the touch pen has been improved. The time required to check the touch sensing function is reduced, and the number of touch panels that can be inspected per unit time is increased. According to the aspect of the present invention, the above and other objects can be achieved by using a device ready to check the touch panel touch sensing function. The touch panel includes a touch pen that has a pen tip and a body that contacts the touch panel, and a bottom plate having a space formed in the upper side for the touch pen to move, and a lower side a receiving hole for receiving the touch pen; an electromagnet mounted under the touch pen to drive the touch pen to reciprocate up and down to contact the touch panel; and a body having an upper side The bottom plate is disposed on the lower side of the electromagnet. Some of the touch pens corresponding to the number of all inspection positions on the touch panel are previously installed in the bottom plate. Touching the pen straight The diameter is smaller than the diameter of the lower end of the pen tip, and the diameter of the bottom plate receiving hole is larger than the diameter of the pen body of the touch pen and smaller than the diameter of the lower end of the pen tip. The electromagnet used in the present invention comprises: an electric coil for forming when supplying power a magnetic field; an iron core driven upward by the magnetic field to drive the touch pen; and a spring mounted along the outer circumference of the core pin for 'shrinking when the core pin is driven' The iron core pin is returned to the initial position when the power is turned off or the polarity is changed. 9 168 According to the aspect of the present invention, the above and other objects can be achieved by a method for inspecting the touch panel touch sensing function using the above device, the method comprising : setting the inspection position of the touch sensing function of the touch panel to be inspected ((χ-], γ_υ to (χ_η Υ_η)); installing a touch pen in advance in all the receiving holes of a bottom plate, wherein many corresponding correspondences are formed The number of the receiving holes to the number of the touch panel «•Hai inspection position; placing the touch panel on the bottom plate so that a touch sensing surface faces the bottom plate; supplying power to an electromagnet In this way, the touch pen immediately contacts the touch panel, and then immediately interrupts the power supply or changes the polarity and returns to the original position. The coordinates of the touch position sensed by the touch pen are evaluated (ΧΒ -1, ΥΒ -1 ) to (ΧΒ -η, ΥΒ-η); and using the coordinate value ((χΒ_〗, γΒ_〇 to (χΒ_η, ΥΒ η))) and a theoretical coordinate value of a normal touch panel ((χΑ ι, γΑ -Ό to (XA-n'YA-n)) is compared to determine a normal touch panel and a poor touch panel. The electromagnet is continuously driven for all inspection positions ((χ_], γ_ ]) to (X η, η η)) ' and the drive sequence and the total time to drive all the electromagnets are subject to the programmable logic controller (pLC) control. According to the present invention, the touch pen is fixed in advance at all inspection positions, and the manner in which the electromagnet is used to drive the touch pen is more than that of the conventional inspection device, and the inspection time can be reduced by using this method. Increase the number of touch panels inspected per unit time while significantly reducing the manufacturing cost of inspection equipment.

The bottom plate 10 has an upper side in which a space 13 for moving the touch pen is formed, and a lower side, in which a receiving hole n for accommodating the touch pen is formed. The bottom plate 10 further has a touch = plate mounting pocket 12 in which the touch panel 50 is placed and the side edges form a positioning step 14 for placing the bottom plate 10 on the body 30. The y touch pen receiving hole 1] is formed by penetrating the bottom plate 10, and its straight cymbal is larger than the pen body 21 of the touch pen 20 and smaller than the lower end of the pen tip 22, so that the touch pen 20 is easy to be placed, easy to move up and down, left and right. And can be supported by the bottom plate 10 to avoid detachment.

When power is supplied through the power input line 44, the core pin 42 is moved upward by the magnetic field in the electric coil 41. ° 1332168 The upper end of the iron core pin 42 will touch the touch pen 2 () and push the touch (9) up. Finally, the tip 22 of the touch pen 2 is touched by the touch sensing surface 51 of the touch panel 50. On the other hand, the spring 43 is disposed around the lower half of the outer circumference of the core pin 42 and is fixed by the body of the electric coil 41 so as to be bundled when the core pin 42 moves upward. When the touch f 20 touches the touch surface to turn off the power or immediately change the polarity, the core pin 42 is returned to the initial position and the touch pen 2 is touched due to the restoring force of the shrinking elastic 43. 〇 Return to the initial position. A method of inspecting the touch panel touch sensing function using the inspection apparatus according to the present invention will be described in detail below. — The concept of the touch panel touch sensing function check method is the same as the traditional inspection method, and the position setting of the touch sensing function, the method of determining the difference between the good product and the defective product, and the touch sensing function checking method are used for the touch. The actual inspection of the sensing function is consistent with the traditional inspection method. The difference between the inspection method of the present invention and the conventional method lies in the movement and operation of the touch pen. First, in the conventional method, the touch sensing surface of the touch panel in which the touch sensing function is to be inspected faces upward, but in the present invention, it faces downward. In other words, the touch panel is placed on the bottom plate of the inspection device such that the touch sensing surface of the touch panel faces the bottom plate. Secondly, the bottom plate of the conventional inspection apparatus has no receiving holes and is flat, but the bottom plate of the inspection apparatus of the present invention is previously formed with a touch pen receiving hole. 1332168 The sheep, the, and the field will be placed on the touch panel after the touch panel touch sensor function is set to check the position (Χ-1, γ_) to (χ_ηΥη). The inspection position (χ_丨, γ_) to (χ_η, Υη) of the bottom plate will be consistent with the position of the touch panel to be inspected and marked, and the holes will be punched at the individual mark positions. Furthermore, in the conventional device, the touch-tip pens for checking the touch sensing function are placed on top of the touch panel to be inspected at predetermined intervals; Φ but in the present invention, the movable touch pens are one by one It is installed in all the mounting holes formed in the bottom plate of the inspection device, and the touch panel is placed thereon. Further, although a pneumatic pressure can be used to drive the touch pen or a mechanical controller that drives the motor, in the present invention, an electromagnet is used to drive the touch pen. In other words, an electromagnet driven by a magnetic device is mounted at the lower end of all the touch pens. The electric coil is electrically connected to form a magnetic field, the core pin is moved by the magnetic field, and the magazine is mounted on the electromagnet to return the core pin to the initial position. • When the electrical connection is momentarily turned on/off or off/on or the electrode is instantaneously changed, the magnetic field changes to move the core pin back to the initial position. At this time, the iron core pin moves the touch pen to touch the touch sensing surface of the touch panel. The spring increases the force returning to the initial position according to the on/off or off/on of the electrical connection and the polarity change, so that the core pin returns to the initial position and touches the pen to return to the initial position. Moreover, the evaluation of the position coordinate value of the touch sensing function by touching the touch panel to touch the touch panel is different from the conventional technology. In the present invention, due to the movement of the electromagnet and the touch pen, the touch panel senses the touch of the touch pen used by the 1332168 for the touch sensing function check, and senses the position coordinate value (XB) for performing the touch sensing function. -l, ΥΒ-1). Further, the § flattening of the continuous 仏 value of the present invention from the position (Χ-1, Υ-1) to the position (Χ_ηΥ_η) is different from the conventional technique. In the present invention, the continuous inspection of the touch sensing function is performed from the first inspection position to the last inspection position, and the electromagnet from the position (Χ-], Υ-1) to the position (Χ_η, γ_η) is continuously driven.

The drive sequence and the time required to drive all of the electromagnets are controlled by a programmable editing logic controller (PLC). The continuous operation at this time is represented by a function of (drive by electromagnet + touch of a touch pen) χ η (number of electromagnets in advance women's clothing). Thus, the coordinates of the position at which the touch is sensed are estimated to be (χΒ_!, YU) to (ΧΒ_η, γΒ_η). “The comparison of coordinate values and the determination of defective products and good products are the same as those of the conventional technology. In other words, the coordinates of the individual inspection positions (Χ-1, Υ-1) to (χ-η, γ_η) for the touch sensing function check are performed. The values (XB ] , YB_〇 to η, η η) are compared with the coordinate values (χΑ ,, γΑ_ι) to (ΧΑ-η, ΥΑ_η) of the theoretical normal touch panel, and when the comparison result is within the predetermined tolerance When the mosquito screen is tested, the touch panel is good, and when the comparison result is not within the predetermined allowable error (4), it can be decided that the control panel is a defective product. The new inspection m-feature according to the present invention is that the individual touch pens are in front of all the e inventions from (X-1 γ_ 1) to (X ν inspection position.) to (Xd), and the ampoule is touched. The movement of the pen device is excluded, and the movement time of the branch is zero (0). Instead, all the time of mounting the electromagnet from the position (χ ιγ ) to the position (χ-η, γ-η) needs to be controlled in advance in the present invention, and the required magnetic field is used to drive the touch. The time of the pen can be set to] All the electromagnetic I of the military body, and drive and control the total time required to install the T-magnet beforehand. A clothing drive: all the electromagnets installed first: time setting 2 =, in the traditional inspection杳The inside of the device will be:] All the inspection positions will be significantly reduced in comparison with the time when the device with the touch pen moves to the inspection position. Different from the traditional inspection equipment of the bottle, the method of the inner electromagnet 0 of the present invention, such that the time required to drive the touch pen by the electromagnet control is significantly shorter than the use of pneumatic pressure or (four) mechanical driving method of the motor to drive the touch The time required for the pen. A second feature of the present invention is to check the touch-sensitive driving function of the touch pen by changing the magnetic field of the electromagnet instead of using the pneumatic pressure or the conventional driving method using the motor spoon to control the touch sensing function of the touch pen. Shiya induction function, so the cost of inspection is cheaper than using pneumatic pressure or motor drive = control. The price of a single electromagnet is 100 () Korean won' is cheaper than any other drive method. In other words, using inexpensive electromagnets, holes are formed in all positions on the bottom plate where the touch-sensitive power is to be inspected, and the individual touch pens are placed in the holes, so that the cost of the electromagnet is higher than the use of pneumatic pressure or use. The total cost of the mechanical drive method of the motor is much cheaper. The following results were obtained for the result of manufacturing a new inspection apparatus according to the present invention and performing an inspection 1332168'. First of all, the number of touch panels that can be inspected has increased significantly compared to conventional touch panel inspection equipment. In more detail, according to the traditional inspection equipment, for the 7-inch touch panel, the number of touch panels that can check the touch sensing function within 24 hours (actual inspection time: 20 hours) is only 5, but according to According to the new inspection apparatus of the present invention, the number of 7-inch touch panels capable of checking the touch sensing function is increased to 5,000 within 24 hours (actual inspection time: 20 hours). Lu Second's procurement and manufacturing costs are significantly lower than traditional touch panel inspection equipment. In more detail, the purchase cost of the conventional touch panel inspection equipment is 100 million won, and the inspection equipment is 50 million won. However, the procurement and assembly cost of the inspection apparatus of the present invention is less than 2 million won. As described above, according to the present invention, the touch pen is fixed in advance at all inspection positions, and the manner in which the electro-magnet is used to drive the touch pen is more outstanding than the conventional # inspection device, and the (four) method can reduce the inspection time', and Significantly increase the number of touch panels inspected per unit time while significantly reducing the manufacturing cost of the inspection equipment.
