Hereinafter, an operation performance inspection apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining in detail the configuration of the operation performance testing apparatus according to the present invention, Figure 2 is a view for explaining the configuration of the loading unit 110 of FIG.

1 and 2, the operation performance testing apparatus 100 according to the present invention includes a loading unit 110, a contacting unit 120, a control unit 150, and a separation unit 160.

The loading unit 110 loads the inspected object 10 that outputs an electrical signal corresponding to the proximity movement or the contact movement of the polymer material. In this case, the inspected object 10 may be a pointing device that outputs an electrical signal corresponding to a displacement caused by the proximity movement or the contact movement of the polymer material 122, and may include an infrared ray (IR), a laser, an electric field ( The electronic device may be a pointing device that outputs an electrical signal corresponding to a displacement caused by close movement or contact movement of a subject (eg, a polymer material or a finger) using one or more of the electric field.

The contact part 120 includes the polymer material 122, and when the test object 10 is loaded by the loading part 110, the polymer material 122 is brought into proximity or contact with the test object 10, and then the triaxial direction ( X-axis, Y-axis, Z-axis) to move the electrical signal from the inspected object (10). A micropattern is formed on the surface of the polymer material 122 which is in close proximity to or in contact with the object 10, and the micropattern is configured to shift displacements of the polymer material 122 from the proximity or contact movement of the polymer material 122. It has a role to make recognition more accurate.

The polymer material 122 used in the present invention may be phantom, synthetic resin, silicone, or protein, which is a biomimetic tissue having an appearance similar in size to a human tissue structure. In this case, the physical and electrical properties of the polymer material 122 may be implemented in the same or similar manner as the human body. For example, when the polymer material is implemented in the shape of a finger, the friction coefficient, elastic modulus, durability, surface pattern (fingerprint), scattering and absorption coefficient, conductivity, and dielectric constant of the IR wavelength band are the same as those of the human finger. Or similarly implemented.

For example, when the inspected object is a pointing device that outputs an electrical signal corresponding to a displacement according to proximity movement or contact movement of a subject by using infrared rays or a laser, in order to inspect the operation performance of the inspected object in the present invention. The polymer material 122 used may be a material having a surface pattern similar to a finger, a friction coefficient, an elastic modulus, durability, a scattering coefficient, an absorption coefficient, and the like. In addition, when the inspected object is a pointing device that outputs an electrical signal corresponding to a displacement due to proximity movement or contact movement of a subject by using an electric field, the polymer material used to test the performance of the inspected object in the present invention. 122 may be a conductive material having a conductivity similar to a finger.

Commonly used phantom materials are gelatin and Agar. Gelatin is a major component of natural polymer protein obtained by hydrolyzing collagen, which is the major protein constituting bone and skin of animals. Melting temperature is 25 ℃ and melting temperature is 35 ℃. In general, the phantom manufacturing process has a property that agar and gelatin samples are not completely dissolved in water, so that they are heated and dissolved. The mixture is added with propane alcohol, formaldehyde and carbon, and then the dissolved additive mixture is cooled and hardened.

On the other hand, the contact portion 120, when the test object 10 is loaded by the loading unit 110, the test object 10 in a state in which the polymer material 122 is in close proximity within 300μm without directly contacting the test object 10 It is desirable to output an electrical signal from Of course, the inspection may be performed by directly contacting the polymer material 122 with the test object 10. However, when the polymer material 122 is continuously contacted with a large number of inspected objects 10 in order to inspect a large number of inspected objects 10, a problem arises in that the durability of the polymeric material is sharply reduced by friction. . Therefore, the test may be performed at a predetermined distance from the polymer object 122 without directly contacting the test object, but within a recognition range of the test object (that is, the electric signal can be output by the proximity of the polymer material). desirable.

The controller 150 controls the operations of the loading unit 110, the contacting unit 120, and the separating unit 160 so that the operation performance test of the inspected object 10 may be sequentially performed, and the inspected object 10 The electrical signal received from the) is tested for the operational performance of the object under test 10 and outputs the result data according to the operational performance test.

In more detail, the controller 150 includes an inspection unit 152, a display unit 154, and a characteristic variable setting unit 156.

The inspection unit 152 receives an electrical signal output from the inspected object 10 in response to the proximity or contact of the polymer material 122 and inspects the operating performance of the inspected object 10 using the received electrical signal. And outputs the result data according to the operation performance test. At this time, the result data according to the operation performance test includes whether the inspected object is defective, the number of inspected objects, defect rate / number, yield rate / number, progress, wear state of the polymer material (durability), polymer material Data may be included when the replacement is due.

The display unit 154 displays the result data according to the operation performance test from the inspection unit 152 to the user (manager).

The characteristic variable setting unit 156 receives a characteristic variable including a physical characteristic value, a chemical characteristic value, an electrical characteristic value, and the like for the polymer material 122 from the user and transmits the characteristic variables to the inspection unit 152. Herein, the physical property value may include a friction coefficient, elastic modulus, durability, and surface patterns of the polymer material, and the chemical property value may include a constituent ratio and a particle size ratio of the polymer material, and the electrical characteristic value may include an IR wavelength band. It may include the scattering coefficient and absorption coefficient, relative dielectric constant, conductivity of. That is, the inspection unit 152 examines the operation performance of the inspected object 10 in consideration of the characteristic variables input through the characteristic variable setting unit 156. The operational performance of the object under test (eg, pointing device) may vary depending on the physical, chemical and electrical properties of the polymeric material. When the test is performed without considering these characteristic variables, the test result may be changed according to the characteristic value of the polymer material, which is a factor that hinders the reliability of the test result. Therefore, in the present invention, the operational performance of the inspected object is examined in consideration of the characteristic variables of the polymer material, and thus, more reliable test results can be obtained.

The separating unit 160 receives the result data according to the operation performance inspection from the inspection unit 152, and separates and collects the inspected object, which is determined to be poor, on the basis of the received result data from the good inspected object.

The loading unit 110 includes a water oil generating unit 112, a water oil removing unit 114, and a connecting unit (not shown) (see FIG. 2).

The oil-water injection unit 112 injects oil and water onto the surface of the test object 10 before the polymer material is brought into or close to the test object 10 by the contact part 120. At this time, the liquid injected from the oil and water injection unit 112 is preferably composed of a component similar to human sweat. When the test subject 10 is the aforementioned pointing device, the pointing device is exposed to an environment affected by liquid (eg, sweat) secreted from the human body in a practical use environment. Thus, in the present invention, the operation performance test can be performed in the environment as close as possible to the actual use environment when the operation performance test of the above-mentioned pointing device, so that a more reliable test result can be obtained.

The oil and water removal unit 114 removes the oil or water remaining on the surface of the inspected object 10 so that the inspected object 10 whose operability performance test is completed by the inspector 152 can be shipped after the operable performance test is completed.

Meanwhile, in the above description and in FIG. 2, the oil-water injection unit 112 is described as being provided in the loading unit 110, but the oil-water injection unit 112 may be provided in the contact unit 120. That is, by spraying oil and water on the surface of the inspected object 10 in the contact portion 120 and the contact portion 120 before the polymer material approaches or contacts the inspected object 10, the same or similar effect as described above is achieved. can do.

Hereinafter, a pointing device that can be applied to an operation performance testing apparatus according to the present invention will be described in detail.

First, a pointing device using an infrared ray (IR) or a laser (Laser) as a light source is a cover housing (not shown) that is illuminated by a light source unit (not shown), the light source unit, or in proximity to or in contact with a subject (eg, a finger, a polymer material). , A light receiving unit (not shown) for detecting the light reflected by the subject, and a light guide unit (not shown) for guiding the light reflected by the subject to the light receiving unit.

The light source unit may be implemented through an infrared light-emitting diode (LED) or a laser diode (LD) corresponding to the amount of illuminance of the required light. LED and LD have a difference in the output amount of light irradiation, LED is used when output is required with a relatively small amount of light, and LD is used when output is required with a relatively large amount of light. Therefore, the LED and the LD used in the light source unit may be selectively used according to the design specifications of the pointing device.

An outer surface (upper surface) of the cover housing is provided with an operation surface to which the subject contacts or approaches to operate the electronic device, and the light receiving unit is provided on the PCB for processing the input optical signal. Accordingly, when the subject is brought into contact with or close to the operation surface, the optical signal input to the light receiving unit changes according to the movement of the subject.

The cover housing may be made of optical plastic to transmit light emitted from the light source. For example, when the light emitted from the light source unit is IR (infrared rays), the optical plastic may be configured to transmit only infrared rays, or the IR resin may be coated on a transparent member (eg, transparent plastic).

The light receiver calculates a displacement value according to the movement of the subject using the changed optical signal, and outputs an electrical signal corresponding thereto. In more detail, the light emitted from the light source unit is emitted to the outside of the cover housing while the subject is not in contact with the operation surface of the cover housing. On the other hand, when a subject such as a finger approaches or comes into contact with the operation surface of the cover housing, the light emitted from the light source unit hits the object and is reflected, and then enters from the light receiving unit through the light guide unit, thereby photographing the image of the subject as an optical signal. .

The light guide unit guides the light to the light detection region of the light receiving unit by passing the light source reflected from the subject. In this case, the light guide unit may perform an aperture function, a light collecting function, a light filtering, and the like.

On the other hand, when the light source unit is implemented through an LED (Light-Emitting Diode), the light guide unit for condensing the incident light and the prism (or reflector) for advancing by refracting the incident light reflected by the subject at a predetermined angle An optical system composed of a condenser lens or the like can be provided. When the light source unit is implemented through a laser diode (LD), the light guide unit includes an illumination hole for illuminating the light emitted from the LD to the cover housing and an entrance hole for guiding the incident light reflected by the subject to the light receiving unit. It can be provided. Here, the configuration of the optical system is not limited to the above configuration, and may be selectively changed according to the design specifications of the pointing device.

Next, a pointing device using an electric field includes a transmitter (not shown) that forms an electric field on a contact surface of a subject (for example, a finger and a polymer material), and receives an electric field changed by contact of the subject, and receives the received electric field from the received electric field. A detection unit (not shown) for detecting a pattern signal and a calculation unit (not shown) for calculating a pattern displacement that changes according to the movement of the subject from the pattern signal may be provided.

The transmitter forms an electric field in the area including the contact surface. In this case, the electric field may be formed through the plate of the metal film.

The detection unit receives the changed electric field of the subject in contact with the electric field area and outputs a pattern signal from the received electric field.

The calculator calculates a pattern displacement that changes according to the movement of the object from the pattern signal output from the detector. For example, when the subject is a user's finger, a fingerprint image is obtained by scanning a pattern of valleys and mountains formed on the surface of the finger.

3 is a flowchart illustrating a method for checking operation performance according to the present invention.

In the operation performance test method according to the present invention, when a test object which outputs an electrical signal corresponding to the proximity or contact of a polymer material is loaded, the polymer material is brought into electrical contact with the test object by bringing the polymer material into proximity or contact with the test object. Causing a signal to be output; Receiving an electrical signal output from the object under test in response to proximity or contact of the polymeric material; Inspecting an operation performance of the object under test using the received electrical signal; And outputting result data according to the operation performance test.

Referring to Figure 3 in more detail, first, the loading unit loads the test object to be tested (S100). Here, when the inspected object is loaded with an electrical signal corresponding to the proximity or contact of the polymer material, the inspected object may be a pointing device that outputs an electrical signal corresponding to the displacement due to the proximity or contact movement of the polymer material. The electronic device may be an apparatus that outputs an electrical signal corresponding to a displacement caused by proximity movement or contact movement of a subject (eg, finger, biomimetic tissue) using at least one of an infrared ray, a laser, and an electric field. And, in step S100, the 'loading' is a step of positioning the test object to a predetermined test position, supplying the power required for driving the test object to the test object, and the test unit and the test object to check the operation performance of the test object By connecting to the operation performance inspection apparatus according to the present invention includes the step of performing the inspection of the operation performance of the inspected object.

When the test object is loaded through the step S100, the contact unit is brought into contact with or close to the polymer material to the electrical signal output from the test object (S110). In close proximity, it is preferable that an electrical signal is output from the inspected object in a state in which the polymer material is brought into proximity within 300 µm without directly contacting the inspected object. Of course, the inspection may be performed by directly contacting the polymer material with the test object. However, when the biomimetic tissue is continuously contacted with a large number of subjects in order to test a large number of subjects, a problem arises in that the durability of the polymer material is sharply degraded by friction. Therefore, it is preferable that the inspection is performed at a predetermined distance apart without directly contacting the polymer material with the test object, but within a recognition range of the test object (that is, an electric signal can be output by the proximity of the polymer material). .

When the electrical signal corresponding to the proximity or contact from the inspected object is output through the step S110, the inspector receives the electrical signal output from the inspected object (S120).

The inspection unit that receives the electrical signal through the step S120 checks the operation performance of the object under test using the signal received from the object under test (S130). At this time, the inspection unit examines the operation performance of the subject under consideration in consideration of characteristic variables including physical characteristic values, chemical characteristic values, and electrical characteristic values for the polymer material previously input from the user.

Next, the inspection unit outputs the result data according to the operation performance test (S140). The result data of the operation performance test includes the defect of the subject, the number of subjects tested so far, the defective rate / number, the yield rate / number, the progress, the wear state of the polymer material (durability), and the replacement of the biomimetic tissue. Data about the scheduled time may be included.

The result data in step S140 is transmitted to the separation unit, and the separation unit determines whether the subject is defective based on the result data (S150), and separates the inspected object that is determined to be inferior in performance from the good inspected object. Process as (S170).

Next, the loading unit measures the impedance and the current consumption for the inspected object determined to be good by the inspector, and determines whether the inspected object is good by comparing with a predefined threshold value (S160).

Then, the separation unit separates the inspected object that is determined to be defective based on the measurement result in step S160 and finally treats it as defective (S170).

According to the present invention as described above, it is possible to solve the problem that the inspection result according to the operation performance test may vary according to the characteristics of the examiner's finger or the subjective judgment criteria of the tester in the conventional operation performance test, as well as the operation performance of the pointing device. A high level of reliability can be ensured with the test results. Furthermore, there is an effect that can reduce the production cost of the product by reducing the labor cost required to check the operation performance of the pointing device.

As described above, the best embodiment has been disclosed in the drawings and the specification. Although specific terms have been used herein, they are used only for the purpose of describing the present invention and are not used to limit the scope of the present invention as defined in the meaning or claims. Therefore, those skilled in the art will understand that various modifications and equivalent other embodiments are possible from this.
