Description

Technical Field

[0001] The present invention relates to a detection workbench, and in particular to a detection workbench and a detection method for an electronic device using the same. Background Art

[0002] With the development of flat panel display technology, various types of display technologies are widely used in daily life. However, the various types of flat panel display panels currently used are mainly liquid crystal display panels that use backlight to provide lighting, so they consume a lot of energy during use. The electrophoretic electronic paper display panel has the characteristics of ultra-low energy consumption and paper-like display, and is gradually occupying a place in the mainstream of future display technology development.

[0003] Although focusing the light source with the photographic light used in current detection technology can solve the problem that the electronic paper display panel requires external light for detection, it will lead to the following problems: (1) The photographic light is large and limits the working space. (2) When the photographic light illuminates the electronic paper display panel, a specific angle is required to focus the light beam. If the angle is offset, the focused light is insufficient, which will affect the lighting detection of the electronic paper display panel, resulting in the inability to effectively limit the light conditions. (3) If it is changed to a desk lamp type, although the space can be effectively reduced, the development generated by the light bar of the desk lamp will cause the reflected light of the light bar to affect the detection of the product when the product is detected. (4) If a desk lamp with a shading sheet is used, although it can effectively improve the problem of the reflected light of the conventional light bar affecting the detection, the brightness of the light source is still insufficient. Therefore, it is necessary to further propose solutions to the problems encountered by current detection technology. Summary of the invention

[0004] In order to solve the above problems, the main purpose of the present invention is to provide a detection workbench and a detection method for electronic devices using the same, so as to solve the problems encountered by the existing detection technology and achieve the effects of controllable light source angle, stable light source, and no space restriction.

[0005] According to one aspect of the present invention, a detection workbench is provided, comprising a lighting box, a work platform and a support frame structure. The lighting box is used to provide a lighting light. The work platform is arranged below the lighting light. The support frame structure is used to support the lighting box and the work platform, wherein the lighting box is rotatably arranged on an upper side of the support frame structure.

[0006] According to one aspect of the present invention, a method for testing an electronic device is provided, which is used for the above-mentioned testing workbench, and the testing method comprises the following steps. An electronic device is placed on the workbench. An illumination light source projects a planar light beam onto a testing surface of the electronic device. The illumination light box is rotated so that the illumination light box can be adjusted to an inclination angle relative to the workbench.

[0007] The advantages of the present invention are:

[0008] The detection workbench and the detection method of the electronic device using the same provided by the present invention are used to solve the problems encountered by the existing detection technology, wherein the lighting box can be rotatably set on an upper side of the support frame structure, so as not to occupy the working space, and the electronic device can be set on the work platform or can be tilted at an angle with a fixture to improve the downward angle of the personnel during visual detection, so as to increase the detection comfort. At the same time, after the lighting box and the support frame structure are combined into one, the structure is stable, and the problem of the existing photographic light colliding with the workbench and being misaligned will not occur. Therefore, the effects of controllable light source angle, stable light source, and unlimited space can be achieved.

[0044] In this specification, many specific details are provided to provide a thorough understanding of the specific embodiments of the present invention; however, those skilled in the art should know that the present invention can still be practiced without one or more of these specific details; in other cases, well-known details are not shown or described to avoid obscuring the main technical features of the present invention. The technical content and detailed description of the present invention are described as follows with the accompanying drawings:

[0045] Figure 1 FIG. 1 is a schematic diagram of a detection workbench 100 according to an embodiment of the present invention. Figure 1The detection workbench 100 includes an illumination light box 110, a work platform 120 and a support frame structure 130. The illumination light box 110 is used to provide an illumination light BL. The work platform 120 is disposed below the illumination light BL. The support frame structure 130 is used to support the illumination light box 110 and the work platform 120, wherein the illumination light box 110 is rotatably disposed on an upper side of the support frame structure 130.

[0046] like Figure 1 As shown, in this embodiment, a whole lighting box 110 is installed above the work table 100. The lighting box 110 projects a plane light beam from top to bottom, and the detection of the electronic device 10 is achieved by lighting from above. Since the lighting box 110 is directly arranged above the work table 100, there is no limitation that a traditional photographic light needs to have a specific angle to focus the light. In addition, the illumination light BL provided by the lighting box 110 is a plane light beam, which can be fully projected on a detection surface 11 of the electronic device 10, and there will be no angle deviation of the traditional photographic light, so there will be no problem of affecting the electronic device 10 when lighting the light for detection.

[0047] In one embodiment, the electronic device 10 is, for example, an electronic paper display or a backlight display. The detection workbench 100 of this embodiment can be used to detect the image clarity, color expression and image quality of the electronic paper display. In addition, the detection workbench 100 of this embodiment can also be used to detect the luminous intensity, color expression and image quality of the backlight display.

[0048] Please refer to Figure 1 The lighting box 110 is, for example, a backlight box for a display. The lighting box 110 has a shading sheet and a plurality of light strips (such as LED light strips). The shading sheet can prevent the problem of light reflected from the light strips affecting detection. In addition, optical materials such as a light guide plate, an anti-reflection film, a diffusion plate or a prism / lenticular sheet can also be used inside the lighting box 110 to increase the light output angle and reduce light reflection. The main function of the light guide plate is to guide the direction of light, improve the brightness of the light output and control the brightness uniformity. The function of the diffusion plate is to make the emitted light distribution more uniform. A prism sheet with a focusing function can also be added to the diffusion sheet to increase the directionality of the emitted light, thereby achieving the purpose of increasing the front brightness.

[0049] In one embodiment, the lighting box 110 may be an edge-lit structure or a direct-lit structure, wherein the light source of the edge-lit structure is disposed on the side of the light guide plate, and the light guide plate is used to transmit the light incident from the edge to the center of the lighting box 110. The light source of the direct-lit structure is disposed behind the diffuser plate, and the diffuser plate is used to evenly distribute the incident light, so that the emitted light distribution is more uniform.

[0050] Please refer to Figure 1, the lighting box 110 includes two rotating shafts 112, and the two rotating shafts 112 are horizontally connected to the opposite sides of the support frame structure 130, so that the lighting box 110 can adjust the tilt angle relative to the work platform 120. The rotating shaft 112 may include components such as a fixing plate, a bearing, and a hinge. The angle of the rotating shaft 112 can be adjusted and can be fixed at any angle by a fastener 114, so that the lighting box 110 is fixed at any angle (for example, 30 degrees or 45 degrees). In addition, in addition to the rotating shaft 112, the lighting box 110 can also be equipped with a single connecting rod, multiple connecting rods, a single rotating arm or multiple rotating arms to increase the functions of lifting and covering, or with the function of a slide slot so that the lighting box 110 can slide up and down or slide left and right. The present invention is not limited to this.

[0051] In addition, the lighting box 110 may further include a dimmer 116, which can adjust the light intensity of the lighting light BL generated by the lighting light source. The dimmer 116 is, for example, a variable resistor or a transistor for adjusting the current intensity, which can change the current flowing through the light bar to change the luminous intensity of the lighting light BL. Therefore, the dimmer 116 can be used to adjust the light intensity of the electronic device 10 with different lighting requirements.

[0052] Please refer to Figure 1 The support frame structure 130 is used to provide the support body required by the lighting box 110, so that the lighting box 110 can irradiate a plane light beam from top to bottom to simulate the actual use situation. The support frame structure 130 includes a first support frame 131, a second support frame 132 and a third support frame 133 connected as a whole. The first support frame 131 is located on the first side of the support frame structure 130, the second support frame 132 is located on the second side of the support frame structure 130, and the third support frame 133 is located on the third side of the support frame structure 130, wherein the first side is opposite to the third side, and the second side is located between the first side and the third side. The lighting box 110 is arranged above the first support frame 131, the second support frame 132, and the third support frame 133, and the working platform 120 is arranged in the space surrounded by the first support frame 131, the second support frame 132, and the third support frame 133, and the support frame structure 130 forms an opening 134 on the fourth side to serve as the entrance / exit required for personnel or mechanical arms to operate.

[0053] Please refer to Figure 1The support frame structure 130 is, for example, a portal frame structure, and the nodes between the beams and the columns are combined with angle steels or steel pipes and fixed together by riveting or welding to increase the overall structural strength. In addition, the support frame structure 130 can be set as a single-layer structure or a multi-layer structure. The top beam structure of the support frame structure 130 is used to place the lighting box 110, and the working platform 120 can be set on the beam structure 135 of the middle layer, so that the height of the lighting box 110 is greater than the height of the working platform 120, and a detection space 101 is formed between the lighting box 110 and the working platform 120.

[0054] Please refer to Figure 1 A power switch 141 and / or at least one power socket 142 may be disposed on the outside of the support frame structure 130, wherein the power switch 141 allows an operator to cut off or connect an external power source, and the power socket 142 allows an external power source to supply power to the lighting box 110 or other detection equipment. In addition, a plurality of rollers 143 and / or a plurality of stoppers 144 may be disposed on the bottom side of the support frame structure 130, wherein the rollers 143 may help the support frame structure 130 to move, and the stoppers 144 may help the support frame structure 130 to position, so as to stabilize the rollers 130 so that they do not rotate.

[0055] Please refer to Figure 2 , which illustrates a schematic diagram of a fixture 122 disposed on a work platform 120 according to an embodiment of the present invention. In one embodiment, the fixture 122 is disposed on the work platform 120, and the fixture 122 has an inclined surface 123 relative to the horizontal surface of the work platform 120 for disposing an electronic device 10. The inclined surface 123 is inclined at an angle θ (e.g., 15 to 30 degrees, but the inclination angle is not limited thereto) relative to the work platform 120. In one embodiment, the fixture 122 is, for example, a rotatable element or is combined with a driver (e.g., a motor) to achieve the function of changing the rotation angle, making the overall detection operation more flexible.

[0056] Please refer to Figure 3 , which illustrates a schematic diagram of an electronic device 10 being grabbed or placed on a work platform 120 by a pick-and-place device 124 according to an embodiment of the present invention. In one embodiment, the detection space 101 can provide the space required for the robot arm to grab or place the electronic device 10 on the work platform 120. The pick-and-place device 124 is disposed at the end of the robot arm. The pick-and-place device 124 may include a sensor 125 and a suction head 126 (or claw). When the sensor 125 detects that the suction head 126 touches the electronic device 10 to be grabbed, the suction force of the suction head 126 is used to extract the electronic device 10 and move it to the detection space 101, so as to place the electronic device 10 on the work platform 120. After the electronic device 10 is detected, the suction force of the suction head 126 is used to extract the electronic device 10 and move it out of the detection space 101 to complete the automated detection.

[0057] Please refer to Figure 3 In this embodiment, an image sensor 127 may be further disposed in the detection space 101. The image sensor 127 is used to detect the detection surface 11 of the electronic device 10, and judge the image quality of the detection surface 11 of the electronic device 10 according to the detection result. The image sensor 127 is, for example, a CMOS image sensor or a CCD image sensor, which uses a photodiode to perform light and electricity conversion, converts image data into digital data, and stores it in a memory, so that the detection personnel can judge the image quality according to the detection result.

[0058] Please refer to Figure 4A and Figure 4B , which respectively illustrate schematic diagrams of a detection workbench 100 simulating an ambient light detection or a sunlight detection according to an embodiment of the present invention. The work platform 120 is disposed on the inner side of the support frame structure 130, and the operator can view the work platform 120 from the outer side of the support frame structure 130 to assist in the detection work. In addition, since the support frame structure 130 is a hollow frame structure and does not block the incident light, the external ambient light CL can be incident on the internal detection space 101 through the outer side of the support frame structure 130 to simulate the ambient light detection. In addition, when the lighting box 110 above is lit, the lighting light BL provided by the lighting box 110 can be used as sunlight in actual use, so that the detection space 101 can be used to simulate a sunlight detection.

[0059] Please refer to Figure 1 and Figure 5 ,in Figure 5 A flow chart of a detection method of an electronic device 10 according to an embodiment of the present invention is shown. The detection method of the electronic device 10 includes the following steps S201 to S205. First, in step S201, an electronic device 10 is placed on a work platform 120. In step S202, an illumination light BL projects a plane beam to a detection surface 11 of the electronic device 10. Next, in step S203, the illumination light box 110 is rotated so that the illumination light box 110 can adjust the tilt angle relative to the work platform 120. Through the above detection, the degree of influence of illumination light BL incident at different angles on the image quality of the electronic device 10 can be known. In addition, in step S204, the detection method of the electronic device 10 may further include adjusting the light intensity of the illumination light BL generated by the illumination light source to simulate an ambient light detection or a sunlight detection. In addition, in step S205, the detection method of the electronic device 10 may further include detecting the detection surface 11 of the electronic device 10 with an image sensor 124, and judging the image quality of the detection surface 11 of the electronic device 10 according to the detection result.

[0060] The detection work table and the detection method of the electronic device using the detection work table described in the above embodiment of the present invention are used to solve the problems encountered by the existing detection technology, wherein the lighting box can be rotatably set on an upper side of the support frame structure, so as not to occupy the working space, and the electronic device can be set on the work platform or can be tilted at an angle with a fixture to improve the downward angle of personnel during visual detection, so as to increase the detection comfort. At the same time, after the lighting box and the support frame structure are combined into one, the structure is stable, and the problem of the existing photographic light colliding with the work table and becoming misaligned will not occur. Therefore, the effects of controllable light source angle, stable light source, and unlimited space can be achieved.
