터치판넬의 검사장치 및 검사방법{An Inspection device of a Touch Panel and inspection method}An inspection device of a touch panel and inspection method

본 발명은 터치판넬의 검사장치에 있어서, 터치판넬에 직접 터치하여 판넬의 전압을 측정한 후 터치판넬의 불량 여부를 판단하는 검사장치 및 검사방법에 관한 것이다.The present invention relates to an inspection apparatus and a method for inspecting a touch panel in which a touch panel is directly touched and a voltage of the panel is measured to determine whether the touch panel is defective.

종래 일반적인 검사장치는 터치판넬에 검사자가 손으로 직접 검사장치를 눌러서 터치판넬의 검사를 실시했었다.In the conventional general inspection apparatus, the inspector pressed the inspection apparatus by hand on the touch panel to inspect the touch panel.

그러나 상기와 같은 종래의 기술은 검사자가 일정한 힘으로 터치판넬에 검사장치를 누르는 데에 한계가 있기 때문에 정확하고 정밀한 검사가 어렵다는 문제점이 있었다.However, the conventional technology as described above has a problem that it is difficult to accurately and precisely inspect because the inspector has a limitation in pressing the inspection device on the touch panel with a constant force.

그리고 검사자마다 누르는 힘과 각도가 다르기 때문에 정확한 검사가 실시될 수가 없었으며, 터치판넬의 검사위치를 일일이 손으로 눌러서 검사해야 하므로 검사시간이 많이 소요되었고 제작공정 전체에도 많은 시간이 소요된다는 문제점이 있었다.And because the pressing force and angle are different for each inspector, the accurate inspection could not be carried out, and the inspection position of the touch panel had to be checked by hand by hand, so it took a lot of inspection time and a lot of time in the whole manufacturing process. .

또한, 검사 결과에 대한 신뢰성을 확보하기가 어렵다는 문제가 있었다.In addition, there was a problem that it is difficult to secure the reliability of the test results.

본 발명은 상기의 문제점을 해결하기 위하여 안출된 것으로서, 검사장치를 자동으로 구성하여 일정한 힘과 일정한 각도로 터치판넬을 검사하므로 검사결과에 대한 신뢰성을 확보하는데에 그 목적이 있다.The present invention has been made in order to solve the above problems, it is an object to ensure the reliability of the inspection results by automatically configuring the inspection apparatus to inspect the touch panel at a constant force and a certain angle.

본 발명의 또 다른 목적은 검사장치를 자동으로 구성하여 검사 시간을 단축하여 제작공정을 개선한 것이다.Another object of the present invention is to improve the manufacturing process by reducing the inspection time by automatically configuring the inspection apparatus.

본 발명은 상기의 목적을 달성하기 위한 것으로서, 상세한 설명은 첨부된 도면을 참조하여 설명하기로 한다.The present invention is to achieve the above object, a detailed description will be described with reference to the accompanying drawings.

It is also.

도 2 내지 도 4에 도시된 바와 같이 본 발명은 터치판넬의 불량 여부를 검사하는 검사장치 및 검사방법에 관한 것으로, 상세하게 설명하자면 가압부(105)에서 터치판넬에 터치(접촉)하는 힘 즉, 검사압력을 서보모터위치제어장치(101)에서 서보모터드라이브(102)로 전달하면 서보모터(103)가 회전하게 되며, 회전운동하는 서보모터(103)는 LM가이드(104)에 의하여 회전운동을 직선운동으로 변환하고, LM가이드(104)는 볼스크류(110)를 따라 직선운동 즉, 승ㆍ하강하게 되며, LM가이드(104)와 가압부(105)는 가압지지부(112)에 의하여 서로 연결되어 있으므로 LM가이드(104)가 하강하면 가압부(105)도 하강하게 되는 구성이다.2 to 4, the present invention relates to an inspection apparatus and an inspection method for inspecting whether or not a touch panel is defective. Specifically, the pressure unit 105 touches (contacts) the touch panel. When the test pressure is transmitted from the servo motor position control device 101 to the servo motor drive 102, the servo motor 103 rotates. The servo motor 103 that rotates is rotated by the LM guide 104. Is converted into a linear motion, the LM guide 104 is a linear motion, that is, rising and falling along the ball screw 110, the LM guide 104 and the pressing portion 105 is mutually by the pressing support portion 112 Since the LM guide 104 is lowered because it is connected, the pressing portion 105 is also lowered.

본 발명의 가압부(105) 에는 가압핀(106)과 완충부재(107) 그리고, 로드셀(Load Cell)(108)로 구성되어 있는데, 상세하게는 가압부(105)의 내부 일측에 로드셀(108)이 내장되고, 그 하부에 완충부재(107)가 구비되며, 완충부재(107)의 하부에는 가압핀(106)이 구비되는데 완충부재(107)는 로드셀(108)과 가압핀(106) 사이에서 상ㆍ하부로 압축과 신축운동을 한다.The pressing unit 105 of the present invention is composed of a pressing pin 106, a buffer member 107, and a load cell 108, and in detail, the load cell 108 inside one side of the pressing unit 105. ) Is built in, the lower portion of the buffer member 107 is provided, the lower portion of the buffer member 107 is provided with a pressing pin 106, the buffer member 107 is between the load cell 108 and the pressing pin 106 Compress and stretch from top to bottom.

여기서, 완충부재(106)는 일반적으로 스프링이 사용되지만 탄성력을 가지는 탄성부재는 적용 가능함을 밝혀둔다.Here, the buffer member 106 is generally used spring, but it turns out that the elastic member having an elastic force is applicable.

가압부(105)의 각 구성을 살펴보면, 가압핀(106)은 주로 끝이 뾰족한 펜 타입으로서 터치판넬에 직접 접촉하게 된다.Looking at each configuration of the pressing unit 105, the pressing pin 106 is mainly a pointed pen type is in direct contact with the touch panel.

본 발명에서 터치판넬에 가압되는 압력 즉, 검사압력은 터치판넬 마다 그 특성이 다르기 때문에 예를들어 설명하자면, 검사압력의 범위를 50g ~ 500g을 기준으로 할 경우 LM가이드(104)에서 발생 되는 직선운동의 압력을 가압부(105)의 가압핀(106)을 통해서 직접 터치판넬에 전달할 경우, 검사범위(50g ~ 500g) 내에서는 검사에 별문제가 없지만 검사범위를 넘어서 1500g이 가해지면 정확한 검사가 어렵고, 터치판넬이 파손될 우려가 있으므로 미세한 압력단위 (1g)까지 제어하기가 쉽지 않는데 그 이유는, LM가이드(104)를 0.5mm만 하강시켜도 가해지는 압력은 1000g 이상이 되기 때문에 검사범위 내의 압력을 가한다는 것은 어렵기 때문에 완충부재(107)를 구비하여 가압력을 보정한다.In the present invention, since the pressure applied to the touch panel, that is, the inspection pressure is different for each touch panel, for example, the straight line generated from the LM guide 104 when the range of the inspection pressure is 50g to 500g. When the pressure of the movement is directly transmitted to the touch panel through the pressing pin 106 of the pressing unit 105, there is no problem in the inspection within the inspection range (50g ~ 500g), but if the 1500g is applied beyond the inspection range, it is difficult to accurately inspect As the touch panel may be damaged, it is not easy to control the minute pressure unit (1g) because the pressure applied is 1000g or more even if the LM guide 104 is lowered by only 0.5mm. Since it is difficult to do so, the shock absorbing member 107 is provided to correct the pressing force.

여기서, LM가이드(104)가 하강하게 되면 가압부(105)가 하강되고 가압핀(106)도 하강하여 터치판넬에 접촉하여 검사압력을 가하고, 그 후 LM가이드(104)는 세팅 값만큼 계속 하강하고 터치판넬과 접속된 가압핀(106)은 일정 힘 이상이 되면 상부의 완충부재(107)로 그 힘을 전달하고 완충부재(107)는 압축되고 그 압축된 힘만큼 로드셀(108)에 전달되고, LM가이드(104)는 하강을 멈추고 상승하게 된다.Here, when the LM guide 104 is lowered, the pressurizing portion 105 is lowered and the pressure pin 106 is also lowered to contact the touch panel to apply a test pressure, and then the LM guide 104 is continuously lowered by a setting value. When the pressure pin 106 connected to the touch panel becomes a predetermined force or more, the force is transmitted to the upper buffer member 107, and the buffer member 107 is compressed and transmitted to the load cell 108 by the compressed force. The LM guide 104 stops descending and rises.

로드셀(108)에서는 완충부재(107)에서 전달된 압력 값을 전압으로 변환하여 출력하고, 그 출력 값을 압력측정부(109)로 전달한다.The load cell 108 converts the pressure value transmitted from the shock absorbing member 107 into a voltage and outputs the voltage, and transmits the output value to the pressure measuring unit 109.

압력측정부(109)에서는 출력전압을 데이터(DATA) 값으로 변환하고, 변환된 데이터 값을 서보모터위치제어장치(101)로 전달하면 서보모터위치제어장치(101)에서 터치판넬에 가해진 데이터 값을 읽어서 원하는 압력 값이 될 때까지 서보모터(103)를 구동하기 위한 신호를 발생시킨다.The pressure measuring unit 109 converts the output voltage into a data value, and transmits the converted data value to the servo motor position control device 101, and then the data value applied to the touch panel by the servo motor position control device 101. The signal is generated to drive the servomotor 103 until the desired pressure value is read.

상기의 방법으로 첫번째 터치판넬의 검사가 완료되면, 순차적으로 그 다음 터치판넬의 검사를 자동으로 수행한다.When the inspection of the first touch panel is completed by the above method, the inspection of the next touch panel is automatically performed sequentially.

본 발명은 상기와 같이 터치판넬 검사에서 종래 수동으로 검사할 경우, 작업자(검사자)의 손의 힘과 각도 등이 정확하지 않음으로 인하여 검사결과에 대한 신뢰성이 감소되고 각 검사 단계를 일일이 손으로 직접 검사해야 되므로 검사시간이 많이 소요되었고, 번거러운 단점을 보완하기 위한 수단으로 검사장치를 자동으로 구성하여 검사시간을 단축하고 일정한 압력과 각도로 검사를 하므로 검사결과에 대한 신뢰성을 향상시킨다.In the present invention, when the manual manual inspection in the touch panel inspection as described above, due to the inaccurate force and angle of the hand of the operator (inspector), the reliability of the inspection result is reduced and each inspection step is directly performed by hand. Test time was taken a lot because it needs to be inspected. As a means to make up for the troublesome shortcomings, the inspection device is automatically configured to shorten the test time and inspect at a constant pressure and angle, thereby improving reliability of the test results.

본 발명은 상기의 구성과 같이 터치판넬의 검사장치에 있어서, 검사장치를 자동으로 구성하여 일정한 힘과 일정한 각도로 터치판넬의 검사를 자동으로 실시하기 때문에 검사소요시간을 단축시키고, 검사에 대한 신뢰성을 확보하는 효과가 있다.According to the present invention, in the inspection apparatus of the touch panel as described above, the inspection apparatus is automatically configured to automatically perform the inspection of the touch panel with a constant force and a certain angle, thereby reducing the inspection time and reducing the reliability of the inspection. It is effective to secure.
