Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of camera testing, and particularly relates to a camera testing system. BACKGROUND

[0002] Now, various electronic devices used by users are all installed with cameras, and through the cameras, various operations such as photographing, code scanning and video chatting can be performed. With the development of science and technology and the improvement of living standards, the requirements of users on the performance of cameras are also continuously improved. For example, professional photographers can take professional photos through professional photographic equipment, and ordinary users also require cameras to have the performance of part of the professional photographic equipment. Therefore, camera manufacturers now all strive to improve the performance of products, and strictly require the quality of cameras, and before leaving the factory, various performance tests must be performed.

[0003] In order to adapt to the testing of cameras, various manufacturers have developed various testing equipment to meet the testing requirements of cameras. For example, the utility model patent with the publication number CN207354511U proposes a photographing test system, which comprises a mobile bearing device and a photographing device. The mobile bearing device comprises a base, a placing seat, a first test plate and a second test plate. The base is provided with a guide rail. The bottom of the placing seat is slidably arranged on the guide rail, and the placing seat is provided with a clamping part. The clamping part comprises a first fixed clamping part and a second fixed clamping part, and the first fixed clamping part and the second fixed clamping part are both provided with clamping openings, and the two clamping openings are oppositely arranged, and the photographing device is placed between the two clamping openings. The first test plate is arranged on the base, and the plate surface is parallel to the photographing surface of the photographing device and is provided with a test card. The second test plate is arranged on the base, and the plate surface is parallel to the photographing surface of the photographing device and is provided with a test card. Through the test system of the patent, photographing at a long distance and a short distance can be realized, and the photographing effect of the camera at different distances can be tested. However, the photographing of the equipment is limited by the test site, and cannot meet the requirements of the photographing distance and range of the existing camera. The system can only test one device at a time, and the mobile phone needs to be manually clamped before testing, so the test efficiency is low. SUMMARY

[0004] In view of this, the present invention aims to provide a camera testing system that employs a mobile robot. A robotic arm picks up multiple devices to be tested, allowing it to be moved to any scene for comprehensive shooting performance testing. The device storage unit has multiple first fixing mechanisms to secure and hold the devices. Alignment marks are provided on both the holding devices and the first fixing mechanisms to facilitate accurate picking up of the devices by the robotic arm. Data transmission units are provided on both the first fixing mechanisms and the robotic arm, corresponding to the data transmission units of the holding devices. A control mechanism is provided on the holding devices, connecting them to the robotic arm via a transfer unit to control the movement of a stylus. This system solves the problems of shooting being limited by the test site and failing to meet the shooting distance and range requirements of existing cameras.

[0044] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0046] The test equipment 300 is movable, and comprises a picking device 310 and a first control device 320. The picking device 310 comprises a mechanical hand 311, the mechanical hand 311 comprising a first quick-connection mechanism 3111 and a first control mechanism 3112, the first control mechanism 3112 comprising a first data transmission unit 31121 and a first switching unit 31122.

[0048] The clamping equipment 100 is detachably fixed on the first fixing mechanism 211, and comprises a first clamping mechanism 110, a second quick-connection mechanism 130 and a second control mechanism 120. The first clamping mechanism 110 is used for clamping the to-be-tested equipment 400. The second quick-connection mechanism 130 is detachably connected with the first quick-connection mechanism 3111. The second control mechanism 120 comprises a third data transmission unit 121, a second switching unit 122 and an operation unit 123. The to-be-tested equipment 400 performs data transmission with the first data transmission unit 31121 or the second data transmission unit 2121 through the third data transmission unit 121. The second switching unit 122 is detachably connected with the first switching unit 31122. The operation unit 123 is connected with the second switching unit 122, and the to-be-tested equipment 400 is operated through the operation unit 123.

[0049] The test system of the present application is divided into two parts, one part is the equipment library 200 where the equipment to be tested is placed, and the other part is the movable robot, that is, the test equipment 300. The first control device 320 is arranged inside the machine table at the lower part of the test equipment 300, which can be a general computer or an industrial computer, and a mechanical arm 312 is arranged at the upper part, the end of the mechanical arm 312 is connected with a mechanical hand 311, the mechanical hand 311 can realize the movement of 6 degrees of freedom under the driving of the mechanical arm 312, which is convenient for picking up the equipment to be tested 400 (electronic equipment provided with a camera, such as a mobile phone, a tablet computer, a notebook computer, a driving recorder, etc., hereinafter taking a mobile phone as an example for description). The first quick connection mechanism 3111 of the mechanical hand 311 is fixed with a first control mechanism 3112 around the first quick connection mechanism 3111, the first data transmission unit 31121 of the first control mechanism 3112 can be any form of adapter unit capable of transmitting data, such as USB, type-c, parallel port, etc., and in the present embodiment, a unit fixed with a type-c plug is preferred. The first adapter unit 31122 is used to control the action of the touch pen and click the shooting key of the mobile phone. The first control device 320 of the test equipment 300 controls the test equipment 300 to move according to the pre-stored specified route or according to the specified route according to the instruction, and the technology can be realized by the existing technology, which will not be described here.

[0050] The equipment library 200 is also provided with a cabinet, and the second control device 220 is arranged inside the cabinet, and the same, it can be a general computer or an industrial computer, etc., and the first control device 320 and the second control device 220 are both provided with a network transmission unit, which can remotely transmit data and communicate with the remote monitoring center. A plurality of first jigs 210 are arranged at the upper part of the cabinet, and the first jigs 210 are used to fix the mobile phone.

[0051] The first fixture 210 is used to fix the mobile phone. In this embodiment, the mobile phone is fixed on the first fixture 210 after being clamped by the clamping device 100. Specifically, the clamping device 100 clamps the mobile phone through the first clamping mechanism 110. The first clamping mechanism 110 can be any structure in the prior art, such as a mobile phone clamping bracket 2113 commonly used to clamp a mobile phone. In this embodiment, the mobile phone is fixed from three directions. A fixed baffle is arranged at one end of the mobile phone in the length direction, and clamping pieces are arranged on both sides of the mobile phone in the width direction. The clamping pieces can be a movable clamping plate and a fixed clamping plate, or two oppositely movable clamping plates. Regardless of the form, the two clamping plates are driven to move by a screw nut and screw structure. In this embodiment, two clamping plates that move in opposite directions synchronously are preferred, which can ensure that the center of the mobile phone is always located at the center of the clamping device 100. The clamping device 100 is connected with the second quick connecting mechanism 130. The first quick connecting mechanism 3111 and the second quick connecting mechanism 130 are connected to realize the picking up of the clamping device 100 by the mechanical hand 311. The quick connection between the first quick connecting mechanism 3111 and the second quick connecting mechanism 130 can be achieved in many ways, such as pneumatic, electric or electromagnetic mechanisms. Preferably, the first quick connecting mechanism 3111 and the second quick connecting mechanism 130 are electromagnetic mechanisms. The generation and elimination of electromagnetism are realized by on-off electricity, so as to realize the quick picking up and releasing of the clamping device 100 by the mechanical hand 311.

[0052] After the mobile phone is fixed by the clamping device 100, data transmission with the second control device 220 is required when the mobile phone is placed in the equipment library 200, such as test parameters, photographed photos, etc. When the clamping device 100 is picked up by the mechanical hand 311, data transmission with the first control device 320 is required before, after and during photographing. Therefore, a third data transmission unit 121 connected with the first data transmission unit 31121 and the second data transmission unit 2121 is arranged on the clamping device 100. As described above, the second data transmission unit 2121 and the first data transmission unit 31121 are the same, both being type-c plugs. The third data transmission unit 121 is a type-c plug with two sockets. Preferably, the two sockets are arranged at the upper end and the lower end. The upper end is connected with the type-c plug of the first data transmission unit 31121 or the second data transmission unit 2121, and the lower end socket is connected with the mobile phone through a data line.

[0053] The first adapter unit 31122 and the second adapter unit 122 are both needle adapters, which are used to control the operation of the operation unit 123. The operation unit 123 is preferably a mechanism provided with a stylus, which is used to touch the shutter key of the mobile phone. As an embodiment, the operation unit 123 includes three operation moving mechanisms arranged along the X-axis, Y-axis and Z-axis directions, the stylus is fixed to one of the operation moving mechanisms, and a driver is arranged on at least the Z-direction moving mechanism to drive the stylus to move up and down, thereby realizing the operation of the shutter key. The operation instruction is sent to the driver by the second control device 220 through the first adapter mechanism and the second adapter mechanism. It should be noted that some mobile phones can trigger the shutter by instructions, and in order to prevent the mobile phone from shaking, the shutter is preferably triggered by instructions.

[0054] Through the test system with the above structure, the mobile phone can be picked up by the robot to a specified place for shooting, various images can be shot according to the situation, for example, indoor scenes, outdoor landscapes, trees and figures, and the camera can be shot comprehensively under indoor light or outdoor natural light. The robot hand 311 can realize fast picking and releasing of the mobile phone, and the whole test process can be automatically realized. During the test, multiple mobile phones can be tested at one time, thereby improving the test efficiency.

[0055] Further, the clamping device 100 further comprises a fixed plate 140, the first clamping mechanism 110, the second quick connection mechanism 130 and the second control mechanism 120 are all fixed on the fixed plate 140. A first alignment mark 141 is arranged on the fixed plate 140, and the first alignment mark 141 is arranged on both sides of the second quick connection mechanism 130. The fixed plate 140 is fixed on the first fixed mechanism 211. At least two positioning holes 142 are arranged on the fixed plate 140.

[0056] Through the first alignment mark 141, when the robot hand 311 picks up the clamping device 100, the first alignment mark 141 can be recognized by the sensor 2114, so that the clamping device 100 can be accurately picked up. The two first alignment marks 141 improve the accuracy. The first quick connection mechanism 3111 and the second quick connection mechanism 130 are disc-shaped, and the two first alignment marks 141 are arranged on both sides of the second quick connection mechanism 130.

[0057] Further, at least one first clamping mechanism 110 is fixed on the fixed plate 140.

[0058] Each clamping device 100 can be provided with a first clamping mechanism 110. Each time the manipulator 311 picks up a clamping device 100, the camera of a mobile phone is tested. If two or more first clamping mechanisms 110 are provided, the manipulator 311 picks up a clamping device 100, and multiple mobile phone cameras can be tested at the same time, thereby improving the test efficiency.

[0059] Further, as shown in Figure 4 The first fixture 210 further includes a bottom plate 213, and the data transmission assembly 212 is fixed on the bottom plate 213. The first fixing mechanism 211 is flexibly connected with the bottom plate 213. The first fixing mechanism 211 includes a U-shaped first fixing frame 2111. Two positioning pins 2112 are arranged at two ends of the first fixing frame 2111 respectively and matched with the positioning holes 142. At least two second alignment marks corresponding to the first alignment marks 141 are arranged on the bottom plate of the first fixing frame 2111.

[0060] The first fixing frame 2111 can move in the X-axis direction and the Y-axis direction within a preset range through flexible connection, and the first fixing frame 2111 can rotate around the Z-axis within a preset range. As an implementation form, the first fixing frame 2111 is connected with the support 2113 through a shaft. The outer part of the shaft is sleeved with a spring. The two ends of the spring abut against the opposite two sides of the first fixing frame 2111 and the support 2113. The shaft is connected with the support 2113 through a linear bearing, and a gap is arranged between the shaft and the linear bearing. Because of the gap, the shaft and the support 2113 can rotate relative to each other, so that the first fixing frame 2111 can move in the X-axis direction and the Y-axis direction and rotate around the Z-axis. Because the gap is small, the rotation angle of the first fixing frame 2111 around the Z-axis is small. Under the action of the spring force, the movement range of the first fixing frame 2111 in the X-axis direction and the Y-axis direction is limited. Under the action of the structure, when there is a small misalignment between the type-c plug and the socket, the misalignment can be compensated, and the smooth connection of the two can be realized.

[0061] The first alignment marks 141 on the fixing plate 140 of the clamping device 100 and the second alignment marks of the first fixing frame 2111 are located at the same position. When the clamping device 100 is picked up, the first alignment marks 141 are recognized, so that the first fastening mechanism 3111 and the second fastening mechanism 130 are accurately connected, and the first data transmission unit 31121 is positionally corresponding to the third data transmission unit 121, thereby facilitating the insertion of the type-c plug into the socket. When the clamping device 100 is fixed on the first fixing mechanism 211, the second alignment marks are recognized, so that the positioning pins 2112 are accurately corresponding to the positioning holes 142, and the second data transmission unit 2121 is positionally corresponding to the third data transmission unit 121, thereby facilitating the insertion of the type-c plug into the socket.

[0062] When the second data transmission unit 2121 is connected with the third data transmission unit 121, there is an error between the position of the type-c plug and the socket, therefore, the first fixing mechanism 211 is flexibly connected with the bottom plate 213, and a slight movement of the first fixing mechanism 211 relative to the bottom plate 213 is generated when being connected, so that the type-c plug is smoothly inserted into the socket.

[0063] Further, a fixing piece 2115 is arranged at each end of the U-shaped first fixing frame 2111, and the fixing piece 2115 is preferably an electromagnetic mechanism, and the fixing plate 140 is made of ferrous material, or a ferrous plate is arranged at a position corresponding to the fixing piece 2115 on the fixing plate 140, and the clamping device 100 is fixed by the electromagnetic mechanism.

[0064] Further, a sensor 2114 is arranged on the plate material at the bottom of the U-shaped first fixing frame 2111, and the sensor 2114 senses whether the clamping device 100 is within a preset distance range, and when it is sensed that the clamping device 100 enters the preset distance range, the fixing piece 2115 is controlled to be powered off by the second control device 220, and the electromagnetic mechanism generates an electromagnetic force to fix the fixing plate 140 of the clamping device 100.

[0065] Further, the first fixing mechanism 211 further comprises two supports 2113, and the two supports 2113 are arranged at two sides of the first fixing frame 2111 in the Y-axis direction, and the two supports 2113 are connected with the first fixing frame 2111 by springs.

[0066] The flexible connection between the first fixing mechanism 211 and the bottom plate 213 is realized by the spring connection.

[0067] Further, the data transmission assembly 212 further comprises a movement driving mechanism 2122, the second data transmission unit 2121 is connected with the movement driving mechanism 2122, and the second data transmission unit 2121 is moved at least in the Y-axis and Z-axis directions by the movement driving mechanism 2122.

[0068] The movement driving mechanism 2122 in the Y-axis direction facilitates the type-c plug to approach the socket, and the movement driving mechanism 2122 in the Z-axis direction drives the type-c plug to be inserted into the socket.

[0069] Further, the second data transmission unit 2121 is flexibly connected with the movement driving mechanism 2122, so that the second data transmission unit 2121 can move in the X-axis and Y-axis directions.

[0070] The second data transmission unit 2121 is flexibly connected with the mobile driving mechanism 2122, further compensating for the error between the type-c plug and the socket.

[0071] Further, as shown in Figure 5 The first control mechanism 3112 further includes a plug-in driving mechanism 31123, the first control mechanism 3112 is flexibly connected with the plug-in driving mechanism 31123, and the first control mechanism 3112 drives the telescopic movement through the plug-in driving mechanism 31123.

[0072] The structure of the first control mechanism 3112 is similar to that of the data transmission assembly 212 of the first jig 210, the difference is that it does not have a Y-axis mobile driving mechanism 2122, but has a plug-in driving mechanism 31123 for driving the plug-in of the type-c plug relative to the socket. Similarly, in order to compensate for the error between the type-c plug and the socket, the first control mechanism 3112 is flexibly connected with the plug-in driving mechanism 31123.

[0073] Further, the mechanical hand 311 further includes an image acquisition mechanism 3113, which is connected with the first quick connection mechanism 3111.

[0074] Through the image acquisition mechanism 3113, the image around the mechanical hand 311 is acquired, and the first alignment mark 141 and the second alignment mark are identified.

[0075] Further, the test equipment 300 further includes a machine table, at least one second fixing mechanism 330 is arranged on the machine table. The second fixing mechanism 330 includes a U-shaped second fixing frame, a positioning pin 2112 is arranged at both ends of the second fixing frame respectively, and the positioning pin 2112 is matched with the positioning hole 142. At least two third alignment marks corresponding to the first alignment mark 141 are arranged on the bottom plate of the second fixing frame. A calibration mechanism 340 is also arranged on the machine table, and the size and range of the shooting picture of the camera are tested by shooting the calibration mechanism 340.

[0076] The second fixing mechanism 330 and the first fixing mechanism 211 have basically the same structure, the difference is that the clamping device 100 fixed on the second fixing mechanism 330 only has a fixing function, and does not involve the plug-in between the type-c plug and the socket, therefore, the second fixing mechanism 330 does not have a flexible connection mechanism.

[0077] Correspondingly, the fixing member 2115 is also arranged at both ends of the U-shaped second fixing frame, and the fixing member 2115 is also an electromagnetic mechanism.

[0078] As an embodiment, the calibration mechanism 340 is a square flat plate for calibrating the camera. Specifically, when testing the camera of a mobile phone, the square flat plate is first photographed, the position of the plate image and the distance between the plate image and the periphery of the picture are observed, and the differences between the images photographed by the cameras of other models of mobile phones are compared, so that corresponding adjustments are made, so that the cameras of different models or different types of products (for example, mobile phones and tablet computers) can take the same pictures, so as to detect the shooting performance of the camera. Preferably, because the area of the machine is limited, the flat plate is supported to a certain height by the supporting legs, and the flat plate protrudes from the surrounding components, so as to facilitate the identification of the image.

[0079] Although the present application is disclosed as above, the present application is not limited thereto. Any person skilled in the art, without departing from the spirit and scope of the present application, can make various changes and modifications, therefore the protection scope of the present application should be limited by the scope defined by the claims.
