Description

[0001] This application is a divisional application filed for the Chinese invention patent application with application number 2023103461418 and application date 2023-04-03. Technical Field

[0002] The present invention relates to the field of testing equipment, and in particular to a viewing angle testing mechanism and method. Background Art

[0003] In optical equipment, the angle formed by the two edges of the lens, with the lens as the vertex and the maximum range through which the image of the target object can pass through, is called the field of view. The size of the field of view angle reflects the field of view of the optical device. In the production and development process of equipment such as flat-screen TVs, in order to determine the field of view of the TV's infrared remote control signal receiver, it is necessary to test the field of view of the TV's infrared remote control signal receiver.

[0004] In the current field of view angle test of television infrared remote control signal receivers, the test is usually carried out by a robot driving the infrared signal transmitter to transmit infrared signals toward the receiver at different positions in space to test the range of effective positions where the infrared signal can be received. During the test process, the robot is required to drive the infrared signal transmitter to move as much as possible along a spherical surface with the receiver lens as the center of the sphere. This is difficult to control and it is difficult to ensure that the end of the robot moves along the spherical surface with high position accuracy. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a viewing angle testing mechanism that can reduce the control difficulty of the testing equipment and improve the testing accuracy.

[0006] The field of view angle testing mechanism of the present invention includes: a fourth frame; an arc-shaped limiting mechanism, which is arranged on the fourth frame; a test assembly, which is movably arranged on the arc-shaped limiting mechanism, and the arc-shaped limiting mechanism can limit the movement of the test assembly so that the test assembly moves along an arc path; and a driving device, which is arranged on the arc-shaped limiting mechanism and is used to drive the test assembly to move along the arc path.

[0007] By applying the above-mentioned field of view angle testing mechanism, during the testing process, the product to be tested can be placed in front of the test component, and then the driving device can be controlled to drive the test component to move to different positions along the arc path under the limit of the arc limit mechanism to test the product to be tested. By testing the effective communication between the test component and the product to be tested, the moving range of the test component on the arc path can be used to determine the field of view angle of the product to be tested. Compared with the solution in the prior art that uses a manipulator to drive the movement of the test component, the movement of the test component along the arc path can be effectively ensured only by the drive of a single driving device, which effectively reduces the control difficulty.

[0028] Reference Figures 1 to 11 This embodiment provides a field of view angle testing device, including a test fixture 100 and a test portion 200, wherein the test fixture 100 is used to fix a product to be tested 400, and the test portion 200 is used to test the field of view angle of the product to be tested 400; in this embodiment, the product to be tested 400 is a flat-screen TV, and the field of view angle testing device of this embodiment is used to test the field of view angle of a remote control infrared signal receiver of a flat-screen TV; of course, the field of view angle testing device of this embodiment can also be used to test the field of view angle of other products.

[0029] like Figure 1 As shown, the base includes a cabinet 110 and a fixing frame 300, wherein the cabinet 110 and the fixing frame 300 are fixedly connected, the entire test fixture 100 is set on the cabinet 110, and the test part 200 is set on the fixing frame 300; wherein, rollers are provided under the fixing frame 300 and the cabinet 110 to facilitate the overall migration of the entire field of view angle test device. In addition, locking devices are provided under the fixing frame 300 and the cabinet 110, which can fix the device to the bottom surface after the entire field of view angle test device is moved to the specified position.

[0030] The testing part 200 is divided into an adjustment part and a viewing angle testing mechanism. The adjustment part is used to adjust the position of the viewing angle testing mechanism as a whole. The viewing angle testing mechanism is used to test the viewing angle of the product 400 to be tested.

[0031] like Figures 8 to 11 As shown, the field of view angle testing mechanism of this embodiment includes: a fourth frame 221; an arc limiting mechanism, which is arranged on the fourth frame 221; a test component 227, which is movably arranged on the arc limiting mechanism, and the arc limiting mechanism can limit the movement of the test component 227, so that the test component 227 moves along an arc path; a driving device, which is arranged on the arc limiting mechanism, and the driving device is used to drive the test component 227 to move along the arc path.

[0032] By applying the above-mentioned field of view angle testing mechanism, during the testing process, the product to be tested can be placed in front of the test component 227, and then the driving device is controlled to drive the test component 227 to move to different positions along the arc path under the limit of the arc limit mechanism to test the product to be tested 400. By testing the effective communication between the test component 227 and the product to be tested 400, the moving range of the test component 227 on the arc path can be used to determine the field of view angle of the product to be tested 400. Compared with the solution in the prior art that uses a manipulator to drive the test component 227 to move, the test component 227 can be effectively ensured to move along the arc path only by being driven by a single driving device, which effectively reduces the control difficulty.

[0033] Among them, the arc-shaped limiting mechanism can limit the test component 227 in a variety of ways, so that the test component 227 moves along an arc path, such as limiting the movement of the test component 227 through an arc track 232 or an arc groove, or by rotating one end of the connecting rod to connect to the fourth frame 221 and the other end to connect to the test component 227, so that the test component 227 moves with the connecting rod as the radius, etc.

[0034] It can be understood that the driving device can also drive the test component 227 to move along the arc path in a variety of ways, such as by using a prime mover such as a motor or a pneumatic motor to drive the connecting rod to rotate, thereby driving the test component 227 to move along the arc path; or by using a prime mover to drive a traction belt or traction rope and other mechanisms, thereby driving the test component 227 to move along the arc path, etc.

[0035] It is worth noting that when the part to be tested of the product to be tested 400 is a signal receiving end, the test component 227 can serve as a signal transmitting end, and the moving angle range of the test component 227 in which the signal transmitted by the test component 227 can be received by the signal receiving end during the test is the field of view angle of the product to be tested 400; and when the part to be tested of the product to be tested 400 is a signal transmitting end, the test component 227 can serve as a signal receiving end, and the moving angle range of the test component 227 in which the signal transmitted by the signal transmitting end of the product to be tested 400 during the test is the field of view angle of the product to be tested 400.

[0036] This embodiment also provides a method for testing a field of view angle, which at least moves the field of view angle testing mechanism of the field of view angle testing device, including the following steps: S100, placing a product under test 400 in front of the field of view angle testing mechanism; S200, controlling a driving device to move a test assembly 227 along an arc path, and recording the angular range of movement of the test assembly 227 when the test assembly 227 is able to establish a communication connection with the product under test 400. The angular range of movement is the field of view angle of the product under test 400. The ability of the test assembly 227 to establish a communication connection with the product under test 400 includes both the ability of the test assembly 227 to receive signals transmitted by the product under test 400 and the ability of the test assembly 227 to receive signals transmitted by the product under test 400. For example, during the testing process of a product under test 400, when the signal transmitted by the test assembly 227 is able to be received by the product under test 400, the range of movement of the test assembly 227 along the arc path is an arc with a central angle of 45°, and the field of view angle of the product under test 400 is 45°.

[0037] like Figure 8 As shown, the viewing angle test device further includes: a rotation drive mechanism, which is arranged on the fourth frame 221, and the rotation drive mechanism can drive the arc limiting mechanism to rotate, and the rotation axis of the arc limiting mechanism coincides with the plane where the arc path is located; specifically, as Figure 8 As shown, the plane where the arc path of the test component 227 moves is Figure 8 The rotation axis of the rotary drive mechanism is located in the plane shown. Figure 1In the state of the field of view angle testing mechanism shown, the plane where the arc path is located is a vertical plane, and the rotary drive mechanism can drive the arc limit mechanism to rotate, so that the plane where the arc path is located also rotates; in step S200, the rotary drive mechanism is controlled to drive the arc mechanism to rotate to different positions, and then drive the test component 227 to move along the arc path and record the moving angle range of the test component 227 when the test component 227 can establish a communication connection with the product to be tested 400; the driving device can drive the test component 227 to move to different positions along an arc, and the rotary drive mechanism can drive the arc limit mechanism to rotate to different positions, so that the test component 227 can move to different positions along the arc after the position is changed. Here, the test component 227 can move along various points within a part of a spherical surface in space to accurately test the field of view range of the product to be tested 400.

[0038] The rotary drive mechanism can also drive the arc limit mechanism to rotate in a variety of ways, such as through a motor or pneumatic motor.

[0039] It is worth noting that the coincidence of the rotation axis of the arc limit mechanism and the plane of the arc path refers to the Figure 8 In the plane shown, the rotation axis of the arc-shaped limiting mechanism coincides with the projection of the arc-shaped path; this does not necessarily mean that the two coincide in space.

[0040] Specifically, if Figures 8 to 10 As shown, the rotary drive mechanism includes: a rotary motor 222, which is arranged on the fourth frame 221, and the rotary motor 222 is used to drive the arc limiting mechanism to rotate; in step S200, the rotary drive mechanism is controlled to drive the arc limiting mechanism to rotate to different positions, and then drive the test component 227 to move along the arc path and record the moving angle range of the test component 227 when the test component 227 can establish a communication connection with the product to be tested 400. Here, the rotary motor 222 can drive the entire arc limiting mechanism to rotate around the axis in the front-to-back direction, wherein the rotary motor 222 can adopt a servo motor or other types of motors such as a stepping motor, which can accurately control the rotation position of the arc limiting mechanism; as shown in FIG. Figure 8 As shown, the fourth frame 221 is provided with bearings and couplings, the bearings are used to support the rotating shaft, and the couplings are used to connect the rotating shaft and the rotating part of the rotating motor 222. In addition, the fourth frame 221 is also provided with a rotation detection mechanism for detecting the rotation position of the rotating shaft and the arc limit mechanism; the rotation detection mechanism can detect the rotation position of the rotating shaft and the arc limit mechanism in a variety of ways, such as detecting the rotation position of the rotating shaft through an encoder, or detecting through the angular displacement sensor of the rotating motor 222; in step S200, the rotation detection mechanism can provide the control system with the rotation position of the arc limit mechanism in real time, so that the system can more accurately control the rotation of the arc limit mechanism.

[0041] like Figures 8 to 11 As shown, in some embodiments, the arc limiting mechanism includes: an end bracket 223, which is arranged on the fourth frame 221; an arc track 232, which is arranged on the fourth frame 221, the arc track 232 extends along an arc path, and the test component 227 slides with the arc track 232; a driving device is used to drive the test component 227 to slide relative to the arc track 232; in step S200, the driving device can drive the test component 227 to move along the arc track 232, ensuring that the test component 227 can move stably along the arc path and test the product 400 to be tested.

[0042] like Figures 8 to 10 As shown, the driving device includes: a moving motor 233, which is arranged on the end bracket 223; a driving wheel 229, which is rotatably arranged on the end bracket 223, and the moving motor 233 is used to drive the driving wheel 229 to rotate; a transmission belt 224, which is in transmission cooperation with the driving wheel 229; an arc-shaped limiter 225, which is arranged on the end bracket 223, and the arc-shaped limiter 225 has a limiter extending along the arc path, and the extension arc of the limiter is concentric with the extension path of the arc track 232; a driven wheel 230, which is rotatably arranged at the end of the arc-shaped limiter 225, and the driven wheel 230 cooperates with the transmission belt 224, and the driven wheel 230 can make The transmission belt 224 abuts the limiting portion; the transmission belt 224 is fixedly connected to the test assembly 227; in step S200, the mobile motor 233 can be controlled to drive the driving wheel 229 to rotate, so that the transmission belt 224 moves. Since the transmission belt 224 is tightened by the driven wheel 230 and abuts on the arc-shaped limiting member 225, the part of the transmission belt 224 abutting the arc-shaped limiting member 225 is fixedly connected to the test assembly 227, so the rotation of the mobile motor 233 can drive the test assembly 227 to change its position on the arc path; it is worth noting that the extension arc of the limiting portion is concentric with the extension path of the arc track 232. Figure 8 The projection of the extended arc of the limiting portion is concentric with the projection of the extended path of the arc track 232 from the perspective of ; it does not mean that the extended arc of the limiting portion is concentric with the extended path of the arc track 232 in space.

[0043] Compared with the method of using an arc-shaped rack drive, using a transmission belt 224 to drive the test component 227 to move can effectively reduce the situation where the arc-shaped rack extends toward both sides of the arc-shaped limit member 225 and interferes with other parts; here, the transmission belt 224 can be implemented by a belt or a chain.

[0044] Specifically, if Figure 8 、 Figure 9As shown, there are two driven wheels 230, and the two driven wheels 230 are respectively located at the two ends of the arc-shaped limit member 225; at this time, the two driven wheels 230 are respectively at the two ends of the arc-shaped limit member 225, pressing the transmission belt 224 backward on the limit portion; ensuring that the part of the transmission belt 224 that abuts the limit portion slides along the arc, driving the test component 227 to move along the arc trajectory.

[0045] like Figure 8 As shown, the driving device also includes a tensioning wheel 231, which is rotatably set on the end bracket 223 and cooperates with the transmission belt 224; wherein, the tensioning wheel 231 is used to tension the pulley moving in the entire closed cycle to improve the transmission accuracy.

[0046] like Figure 10 、 Figure 11 As shown, the transmission belt 224 is a synchronous belt, and the test component 227 is fixedly connected to the meshing block 234, which meshes with the synchronous belt; wherein the tooth block on the meshing block 234 is inserted into the tooth groove on the synchronous belt, and the meshing block 234 is connected to the test component 227 through the meshing connector 235. At this time, the synchronous belt can drive the test component 227 to move along the arc path.

[0047] like Figure 10 As shown, the driving device also includes a position detection device arranged on the end bracket 223, and the position detection device is used to detect the position of the test component 227 relative to the arc track 232; in step S200, the position detection device can detect the moving position of the test component 227 on the arc path, which is convenient for detection and control; wherein, the position detection device can detect the position of the test component 227 in a variety of ways; for example, an encoder is set at the rotating shaft of the moving motor 233, and the movement amount of the position of the test component 227 is calculated by detecting the rotation amount of the moving motor 233; or a position sensor extending along the arc path is set on the end bracket 223 to directly detect the moving position of the test component 227.

[0048] like Figure 8 As shown, the viewing angle test mechanism further includes: a rotation drive mechanism, which is arranged on the fourth frame 221, and the rotation drive mechanism can drive the end bracket 223 to rotate, the rotation axis of the end bracket 223 and the radius of the extension arc of the limiting portion are collinear, and the extension arc of the extension portion is located on both sides of the rotation axis of the end bracket 223. Particularly, referring to Figure 8From the perspective shown, the rotation axis of the end bracket 223 is the rotation axis of the rotary motor 222, which extends horizontally in the front-to-back direction; and the extension arc of the extension portion is located at equal angles on the upper and lower sides of the rotation axis, which is approximately 70°; in step S100, the driving device can be controlled to move the test component 227 to the middle position of the arc path. At this time, the center of the arc path and the test component 227 are located in the same horizontal plane, and the position of the test part of the product 400 to be tested is set in front of the test component 227 at a position close to the radius of the arc path; in step S200, the test component 227 moves to various positions along the arc path, and its distance from the test part is approximately equal, which greatly improves the field of view angle test accuracy.

[0049] like Figure 8 As shown, the field of view angle testing mechanism also includes a positioning rod 228, which is detachably connected to the test assembly 227; in step S100, the positioning rod 228 is installed on the test assembly 227, and the position of the field of view angle testing mechanism and / or the product to be tested 400 is adjusted so that the end of the positioning rod 228 is located at the test position of the product to be tested 400, and then the positioning rod 228 is removed. The end position of the positioning rod 228 is the center of the arc path. This calibration step can make the test part of the product to be tested 400 as close to the center of the arc path of the test assembly 227 as possible; in the test of step S200, the test assembly 227 moves to various positions along the arc path, and its distance from the test part is roughly equal, which greatly improves the field of view angle test accuracy.

[0050] like Figure 6 、 Figure 7 As shown, the adjustment part is arranged on the base, and the adjustment part specifically includes: a first frame 211, which is arranged on the base; a second frame 212, which is arranged on the first frame 211 and is slidably connected to the first frame 211 along the up-down direction; a third frame 214, which is arranged on the second frame 212 and is slidably connected to the second frame 212 along the front-back direction; a field of view angle testing mechanism, which is arranged on the third frame 214; and an adjustment device for adjusting the up-down position of the second frame 212 relative to the first frame 211, and / or the front-back position of the third frame 214 relative to the second frame 212.

[0051] Using the above-mentioned field of view angle testing device, during the test process, the device under test can be placed in front of the test assembly 227, and then the adjustment device is controlled to adjust the vertical position of the second frame 212 and / or the front-to-back position of the third frame 214 so that the field of view angle testing mechanism is located in a suitable position, and then the field of view angle test can be started. Compared with the existing technology, it can effectively improve the test adaptability for products under test 400 of different sizes and specifications; that is, in step S100, by adjusting the vertical position of the second frame 212 relative to the first frame 211 and / or the front-to-back position of the third frame 214 relative to the second frame 212, the position of the tested part of the product under test 400 can be made as close as possible to the center of the arc path, thereby improving the test accuracy.

[0052] Among them, the adjustment device can adjust the upper and lower positions of the second frame 212 relative to the first frame 211, and / or the front and rear positions of the third frame 214 relative to the second frame 212 in a variety of ways; for example, the upper and lower positions of the second frame 212 relative to the first frame 211, and / or the front and rear positions of the third frame 214 relative to the second frame 212 can be adjusted by multiple independently arranged motor screw mechanism modules or motor gear rack modules.

[0053] like Figure 7 、 Figure 8 As shown, the adjustment device includes a worm screw lifter arranged on the first frame 211, and the lifting screw 218 of the worm screw lifter abuts the second frame 212; wherein the worm screw lifter is a commonly used lifting position adjustment device, which has a reverse self-locking function. After the adjustment is completed, it can enable the second frame 212 to better maintain the current up and down position, ensuring the stability of the up and down position of the field of view angle test mechanism during the test link of step S200.

[0054] Specifically, a lifting hand wheel 213 is provided on the worm screw lifter, and the lifting hand wheel 213 is used to drive the lifting screw 218 to rotate; wherein, the on-site operator can adjust the upper and lower positions of the second frame 212 by rotating the hand wheel.

[0055] like Figure 6 As shown, lifting sliders are provided on the left and right sides of the second rack 212, and lifting rails are provided on the first rack 211. The lifting rails extend in the up and down directions, and the lifting sliders slide in cooperation with the lifting rails; wherein the lifting sliders and the lifting rails can ensure the stable lifting of the second rack 212 relative to the first rack 211.

[0056] like Figure 6 、 Figure 7As shown, the adjustment device includes: a translation screw 217, which is rotatably set on the second frame 212, and the translation screw 217 extends in the front-to-back direction; a translation nut, which is fixedly set on the third frame 214, and the translation nut is threadedly engaged with the translation screw 217; in step S100, the front-to-back position of the third frame 214 can be adjusted by rotating the translation screw 217, so that the position of the part to be tested of the product to be tested 400 is as close as possible to the center of the arc path; in addition, the screw nut mechanism has good self-locking performance, which can ensure that the third frame 214 maintains the adjusted position well after the adjustment is completed.

[0057] refer to Figure 6 The adjusting device also includes a translation handwheel 215 fixedly arranged on the translation screw rod 217, and the translation handwheel 215 is used to drive the translation screw rod 217 to rotate; at this time, the on-site operator can adjust the front and rear position of the third frame 214 by rotating the translation handwheel 215; in addition, the adjusting device also includes a locking handle 216 arranged on the second frame 212, and the locking handle 216 is used to lock the translation screw rod 217; when the front and rear position of the third frame 214 is adjusted, the locking handle 216 can be controlled to lock the translation screw rod 217 to prevent the front and rear position of the third frame 214 from changing due to the rotation of the translation screw rod 217, thereby affecting the test accuracy.

[0058] like Figure 6 As shown, translation sliders are provided on the left and right sides of the third frame 214, and translation rails extending in the front-to-back direction are provided on the second frame 212, and the translation sliders are slidably matched with the translation rails; here, the sliding match between the translation sliders and the translation rails can ensure that the third frame 214 slides smoothly back and forth relative to the second frame 212.

[0059] like Figure 1 As shown, a transverse slide is provided on the base, and the transverse slide extends in the left-right direction, and the first frame 211 slides with the transverse slide; specifically, the transverse slide is provided on the fixed frame 300, and in step S100, the first frame 211 can slide left and right relative to the transverse slide to adjust the relative position of the product to be tested 400 and the field of view angle test mechanism.

[0060] like Figures 1 to 5 As shown, the viewing angle test device further includes a test fixture 100 provided on a base. The test fixture 100 is used to load the product 400 to be tested. The test fixture 100 is located at the rear side of the viewing angle test mechanism.

[0061] Specifically, the test fixture 100 includes: a transverse guide rail 130, which is arranged on the base and extends in the left-right direction; an edge slider 141, which is arranged on the transverse guide rail 130 and slides with the transverse guide rail 130; a supporting portion, which is fixedly arranged on the edge slider 141 and is used to support the product 400 to be tested; and a locking device, which is used to lock the relative position of the edge slider 141 and the transverse guide rail 130 or unlock it.
