[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 can pass 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 flat-panel TVs and other equipment, 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 manipulator 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 manipulator 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, which is difficult to control and it is difficult to ensure that the end of the manipulator moves along the spherical surface with a 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, which can reduce the control difficulty of the testing equipment and improve the testing accuracy.

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

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Reference Figures 1 to 11 The present embodiment provides a viewing angle testing device, including a testing fixture 100 and a testing part 200, wherein the testing fixture 100 is used to fix a product to be tested 400, and the testing part 200 is used to test the viewing angle of the product to be tested 400; in the present embodiment, the product to be tested 400 is a flat-screen TV, and the viewing angle testing device of the present embodiment is used to test the viewing angle of a remote control infrared signal receiver of the flat-screen TV; of course, the viewing angle testing device of the present embodiment can also be used to test the viewing 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 arranged on the cabinet 110, and the test part 200 is arranged on the fixing frame 300; wherein, rollers are arranged under the fixing frame 300 and the cabinet 110 to facilitate the overall migration of the entire field of view angle test device, and in addition, locking devices are arranged under the fixing frame 300 and the cabinet 110, and after the entire field of view angle test device is moved to a specified position, the device can be fixed to the bottom surface.

[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, and 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-shaped limiting mechanism, which is arranged on the fourth frame 221; a test component 227, which is movably arranged on the arc-shaped limiting mechanism, and the arc-shaped limiting mechanism can limit the movement of the test component 227, so that the test component 227 moves along an arc-shaped path; a driving device, which is arranged on the arc-shaped limiting mechanism, and the driving device is used to drive the test component 227 to move along the arc-shaped 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 400 to be tested. 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 of using a manipulator to drive the test component 227 to move in the prior art, 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 by an arc track 232 or an arc groove, or by rotating one end of the connecting rod to be connected to the fourth frame 221 and the other end to be connected 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. For example, a prime mover such as a motor or a pneumatic motor can be used to drive the connecting rod to rotate, thereby driving the test component 227 to move along the arc path; or a prime mover can be used to drive a traction belt or a traction rope, 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 400 to be tested 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 400 to be tested; and when the part to be tested of the product 400 to be tested 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 400 to be tested can be received during the test is the field of view angle of the product 400 to be tested.

[0036] The present embodiment also provides a method for testing a field of view angle, at least moving the field of view angle testing mechanism of the field of view angle testing device, including the following steps: S100, placing the product 400 to be tested in front of the field of view angle testing mechanism; S200, controlling the driving device to drive the test component 227 to move along the arc path, and recording the moving angle range of the test component 227 when the test component 227 can establish a communication connection with the product 400 to be tested; the moving range is the field of view angle of the product 400 to be tested, wherein the ability of the test component 227 to establish a communication connection with the product 400 to be tested includes both the situation that the signal emitted by the product 400 to be tested can be received by the test component 227 and the situation that the signal emitted by the test component 227 can be received by the product 400 to be tested; for example, during the test process of a certain product 400 to be tested, when the signal emitted by the test component 227 can be received by the product 400 to be tested, the moving range of the test component 227 on the arc path is an arc with a central angle of 45°, and the field of view angle of the product 400 to be tested 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-shaped limiting mechanism to rotate, and the rotation axis of the arc-shaped 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 located 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 test 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 400 to be tested; 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, and 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 400 to be tested.

[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 a pneumatic motor.

[0039] It is worth noting that the coincidence of the rotation axis of the arc limit mechanism and the plane where the arc path is located refers to 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, 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, wherein 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 with 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 by an encoder, or detecting by an angular displacement sensor of the rotating motor 222, etc.; 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, and 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 stably move 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 cooperates with the driving wheel 229 for transmission; an arc-shaped limiter 225, which is arranged on the end bracket 223, and the arc-shaped limiter 225 has a limiter extending along an 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 to 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, Figure 8 , Fig. 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 backwards onto the limit portion, ensuring that the part of the transmission belt 224 abutting the limit portion slides along the arc, driving the test assembly 227 to move along the arc track.

[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 the tensioning wheel 231 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 Fig.10 , Fig.11 As shown, the transmission belt 224 is a synchronous belt, and the test component 227 is fixedly connected with an engagement block 234, which engages with the synchronous belt; wherein the tooth block on the engagement block 234 is inserted into the tooth groove on the synchronous belt, and the engagement block 234 is connected to the test component 227 through the engagement connector 235, and at this time the synchronous belt can drive the test component 227 to move along the arc path.

[0047] like Fig.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 arranged 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 arranged 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 also 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 is collinear with the radius of the extension arc of the limiting portion, 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 rotating 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 both sides of the rotation axis, which is approximately 70°; in step S100, the drive device can be controlled to move the test component 227 to the middle position of the arc path, at which time the center of the arc path and the test component 227 are located in the same horizontal plane, and the position of the tested part of the product 400 to be tested is set in front of the test component 227 at a distance close to the radius of the arc path; in step S200, the test component 227 moves to various positions along the arc path, and the distances from the tested part are approximately equal, which greatly improves the accuracy of the field of view angle test.

[0049] like Figure 8 As shown, the viewing angle testing mechanism also includes a positioning rod 228, and the positioning rod 228 is detachably connected to the test component 227; in step S100, the positioning rod 228 is installed on the test component 227, and the position of the viewing 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 portion of the product to be tested 400 as close to the center of the arc path of the test component 227 as possible; in the test of step S200, the test component 227 moves to various positions along the arc path, and its distance from the test portion is roughly equal, which greatly improves the accuracy of the viewing angle test.

[0051] By using the above-mentioned field of view angle testing device, during the test process, the device to be tested can be placed in front of the test assembly 227, and then the adjustment device is controlled to adjust the up and down position of the second frame 212 and / or the front and back position of the third frame 214, so that the field of view angle testing mechanism is located at a suitable position, and then the field of view angle test is started; compared with the prior art, the test adaptability for the products to be tested 400 of different sizes can be effectively improved; that is, in step S100, the position of the part to be tested of the product to be tested 400 can be made as close to the center of the arc path as possible by adjusting the up and down position of the second frame 212 relative to the first frame 211, and / or the front and back position of the third frame 214 relative to the second frame 212, 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 are adjusted by multiple independently arranged motor screw mechanism modules or motor gear rack modules.
