[0043] In the present invention, the descriptions involving "first", "second", "upper", "lower", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", "upper", "lower" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the technical solutions between the embodiments can be combined, they are all within the protection scope required by the present invention.

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

[0045] like Figures 1 to 5 As shown, a camera test system is used to test the function of a camera of a device to be tested 400 . The test system includes: a test device 300 , a device library 200 and a clamping device 100 .

[0046] The test device 300 is movable, and includes: a picking device 310 and a first control device 320. The picking device 310 includes a manipulator 311, and the manipulator 311 includes a first quick-connect mechanism 3111 and a first control mechanism 3112. The first control mechanism 3112 includes a first data transmission unit 31121 and a first switching unit 31122. The first control device 320 is connected to the first control mechanism 3112.

[0047] The equipment library 200 includes a second control device 220 and at least one first fixture 210 , wherein the first fixture 210 includes a first fixing mechanism 211 and a data transmission component 212 , wherein the data transmission component 212 includes a second data transmission unit 2121 , and the data transmission component 212 is connected to the second control device 220 .

[0048] The clamping device 100 is detachably fixed on the first fixing mechanism 211, and includes: a first clamping mechanism 110, a second quick-connect mechanism 130, and a second operating mechanism 120. The first clamping mechanism 110 is used to clamp the equipment to be tested 400. The second quick-connect mechanism 130 is detachably connected to the first quick-connect mechanism 3111. The second operating mechanism 120 includes: a third data transmission unit 121, a second switching unit 122, and an operating unit 123. The equipment to be tested 400 transmits data 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 to the first switching unit 31122. The operating unit 123 is connected to the second switching unit 122, and the equipment to be tested 400 is operated through the operating unit 123.

[0049] The test system of the present application is divided into two parts, one part is the equipment library 200 for placing the equipment to be tested, and the other part is a movable robot, that is, the test equipment 300. A first control device 320 is provided inside the machine at the lower part of the test equipment 300, which can be an ordinary computer or an industrial computer, and a mechanical arm 312 is installed on the upper part. The end of the mechanical arm 312 is connected to the manipulator 311. The manipulator 311 can achieve 6 degrees of freedom under the drive of the mechanical arm 312, which is convenient for picking up the equipment to be tested 400 (electronic equipment with a camera, such as a mobile phone, a tablet computer, a notebook, a driving recorder, etc., and the following takes a mobile phone as an example for explanation). A first control mechanism 3112 is fixed around the first quick-connect mechanism 3111 of the manipulator 311. 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. In this embodiment, it is preferably a unit with a type-c plug fixed. The first adapter unit 31122 is used to control the action of the stylus and click the camera button of the mobile phone. The first control device 320 of the test device 300 controls the test device 300 to move along a pre-stored prescribed route or along a designated route according to instructions. This technology can be implemented using existing technology and will not be described in detail here.

[0050] The equipment library 200 is also provided with a cabinet, and a second control device 220 is provided inside the cabinet. Similarly, it can be a common computer or an industrial computer, etc. 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 fixtures 210 are provided on the upper part of the cabinet, and the first fixtures 210 are used to fix the mobile phone.

[0051] The method of fixing the mobile phone by the first fixture 210 is to fix the mobile phone on the first fixture 210 after clamping it by the clamping device 100 in this embodiment. Specifically, the clamping device 100 clamps the mobile phone by the first clamping mechanism 110. The first clamping mechanism 110 can be any structure of the prior art, for example, a mobile phone clamping bracket 2113 commonly used for clamping mobile phones, etc. In this embodiment, the mobile phone is fixed from three directions, a fixed baffle is provided at one end of the length direction of the mobile phone, and clamping members are provided on both sides of the width of the mobile phone. The clamping members can be a movable clamping plate and a fixed clamping plate, or two relatively movable clamping plates. Regardless of the form, the two clamping plates are driven to move by the structure of the nut screw. In this embodiment, it is preferred that two clamping plates move synchronously in opposite directions, 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 to the second quick-connect mechanism 130, and the manipulator 311 picks up the clamping device 100 through the connection between the first quick-connect mechanism 3111 and the second quick-connect mechanism 130. The quick connection between the first quick-connect mechanism 3111 and the second quick-connect mechanism 130 can be achieved in many ways, for example, by pneumatic, electric or electromagnetic connection. Preferably, the first quick-connect mechanism 3111 and the second quick-connect mechanism 130 are electromagnetic mechanisms, and the generation and elimination of electromagnetics are achieved by turning the power on and off, thereby enabling the manipulator 311 to quickly pick up and release the clamping device 100.

[0052] After the mobile phone is fixed by the clamping device 100, when it is placed in the equipment library 200, it needs to transmit data with the second control device 220, for example, test parameters, photos taken, etc. After the clamping device 100 is picked up by the manipulator 311, data transmission needs to be carried out with the first control device 320 before, after and during shooting. Therefore, a third data transmission unit 121 connected to the first data transmission unit 31121 and the second data transmission unit 2121 is provided on the clamping device 100. As described above, the second data transmission unit 2121 is the same as the first data transmission unit 31121, both of which are type-c plugs, and 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 to 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 to the mobile phone through a data cable.

[0053] The first adapter unit 31122 and the second adapter unit 122 both use a pin-type adapter for controlling the action of the operating unit 123. The operating unit 123 is preferably provided with a mechanism for a stylus for touching the shutter key of the mobile phone. As an embodiment, the operating unit 123 includes three operating mobile mechanisms arranged along the three directions of the X-axis, the Y-axis and the Z-axis, the stylus is fixed on one of the operating mobile mechanisms, and at least a driver is provided on the Z-direction mobile mechanism to drive the stylus to move up and down to operate the shutter key. The operating instruction is sent by the second control device 220 to a driver through the first adapter mechanism and the second adapter mechanism. It should be noted that some mobile phones can trigger the shutter in the form of instructions. In order to prevent the mobile phone from shaking, it is preferred to trigger the shutter through instructions.

[0054] Through the test system of the above structure, it is possible to realize that the robot picks up the mobile phone and takes it to the designated place to take pictures. Various images can be taken according to the situation, for example, indoor scenes, outdoor landscapes, trees, and people. They can be taken under indoor lighting or outdoor natural light, and the camera can be fully tested for shooting. The manipulator 311 can quickly pick up and release the mobile phone through the electromagnetic mechanism, and the entire test process can be automatically realized. During the test, the test process of multiple mobile phones can be carried out at one time, which improves the test efficiency.

[0055] Furthermore, the clamping device 100 further includes a fixing plate 140, and the first clamping mechanism 110, the second quick-connect mechanism 130 and the second operating mechanism 120 are all fixed on the fixing plate 140. A first alignment mark 141 is provided on the fixing plate 140, and one first alignment mark 141 is provided on each side of the second quick-connect mechanism 130. The fixing plate 140 is fixed on the first fixing mechanism 211. At least two positioning holes 142 are provided on the fixing plate 140.

[0056] Through the first alignment mark 141, when the manipulator 311 picks up the clamping device 100, the first alignment mark 141 is identified by the sensor 2114, and the clamping device 100 can be accurately picked up. Two first alignment marks 141 are provided to improve accuracy. The first quick-connect mechanism 3111 and the second quick-connect mechanism 130 are disc-shaped, and the two first alignment marks 141 are respectively provided on both sides of the second quick-connect mechanism 130.

[0057] Furthermore, at least one of the first clamping mechanisms 110 is fixed on the fixing 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, it tests the camera of a mobile phone. If more than two first clamping mechanisms 110 are provided, the manipulator 311 picks up a clamping device 100, and multiple mobile phone cameras can be tested simultaneously, thereby improving the test efficiency.

[0059] Further, such as Figure 4 As shown, the first fixture 210 also includes a bottom plate 213, the data transmission component 212 is fixed on the bottom plate 213, and the first fixing mechanism 211 is flexibly connected to the bottom plate 213. The first fixing mechanism 211 includes a U-shaped first fixing frame 2111, and a positioning pin 2112 matching the positioning hole 142 is respectively provided at both ends of the first fixing frame 2111, and at least two second alignment marks corresponding to the first alignment mark 141 are provided on the plate at the bottom of the first fixing frame 2111.

[0060] The first fixing frame 2111 can move in a preset range along the X-axis direction and the Y-axis direction through a flexible connection, and the first fixing frame 2111 can rotate around the Z-axis within a preset range. As an embodiment, the first fixing frame 2111 is connected to the bracket 2113 through an axis, and a spring is provided on the outer sleeve of the axis. The two ends of the spring abut against the two opposite sides of the first fixing frame 2111 and the bracket 2113. The axis and the bracket 2113 are connected through a linear bearing, and a gap is provided between the axis and the linear bearing. Because the gap allows the axis and the bracket 2113 to rotate relative to each other, the first fixing frame 2111 can move in the X-axis and Y-axis directions and rotate around the Z-axis. Due to the small gap, the rotation angle of the first fixing frame 2111 around the Z-axis is limited. Under the action of the spring force, the movement range of the first fixing frame 2111 in the X-axis and Y-axis directions is limited. Under the action of this structure, when there is a small misalignment between the type-c plug and the jack, the misalignment can be compensated to achieve a smooth connection between the two.

[0061] The first alignment mark 141 on the fixing plate 140 of the clamping device 100 and the second alignment mark on the first fixing frame 2111 are located at the same position. When picking up the clamping device 100, the first alignment mark 141 is identified to ensure that the first quick-connect mechanism 3111 and the second quick-connect mechanism 130 are accurately connected, and the first data transmission unit 31121 corresponds to the position of the third data transmission unit 121, so as to facilitate the insertion of the type-c plug into the socket. When fixing the clamping device 100 on the first fixing mechanism 211, the second alignment mark is identified to ensure that the positioning pin 2112 corresponds to the positioning hole 142 accurately, and the second data transmission unit 2121 corresponds to the position of the third data transmission unit 121, so as to facilitate the insertion of the type-c plug into the socket.

[0062] When the second data transmission unit 2121 is connected to the third data transmission unit 121, there is an error in the position between the type-c plug and the socket. Therefore, the first fixing mechanism 211 is flexibly connected to the base plate 213. When connected, the first fixing mechanism 211 moves slightly relative to the base plate 213, so that the type-c plug can be smoothly inserted into the socket.

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

[0064] Furthermore, a sensor 2114 is provided on the plate 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. When it is sensed that the clamping device 100 enters the preset distance range, the second control device 220 controls the fixing member 2115 to cut off power, and the electromagnetic mechanism generates electromagnetic force to fix the fixing plate 140 of the clamping device 100.

[0065] Furthermore, the first fixing mechanism 211 further includes two brackets 2113 , which are respectively arranged on both sides of the first fixing frame 2111 in the Y-axis direction, and the two brackets 2113 are connected to the first fixing frame 2111 via springs.

[0066] A flexible connection between the first fixing mechanism 211 and the base plate 213 is achieved by a spring connection.

[0067] Furthermore, the data transmission component 212 also includes a mobile driving mechanism 2122, the second data transmission unit 2121 is connected to the mobile driving mechanism 2122, and the second data transmission unit 2121 is moved at least along the Y-axis and Z-axis directions through the mobile driving mechanism 2122.

[0068] By moving the driving mechanism 2122 in the Y-axis direction, the type-c plug can be close to the socket, and by moving the driving mechanism 2122 in the Z-axis direction, the type-c plug is driven to be inserted into the socket.

[0069] Furthermore, the second data transmission unit 2121 is flexibly connected to the moving drive mechanism 2122, so that the second data transmission unit 2121 can move along the X-axis direction and the Y-axis direction.

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

[0071] Further, such as Figure 5 As shown, the first control mechanism 3112 also includes a plug-in drive mechanism 31123 , the first control mechanism 3112 is flexibly connected to the plug-in drive mechanism 31123 , and the first control mechanism 3112 is driven to telescopically move through the plug-in drive mechanism 31123 .

[0072] The structure of the first control mechanism 3112 is similar to that of the data transmission component 212 of the first fixture 210, except that it does not have a Y-axis moving drive mechanism 2122, but has a plug-in drive mechanism 31123 for driving the plug-in and pull-out 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 to the plug-in drive mechanism 31123.

[0073] Furthermore, the manipulator 311 also includes an image acquisition mechanism 3113 , and the image acquisition mechanism 3113 is connected to the first quick-connect mechanism 3111 .

[0074] The image acquisition mechanism 3113 acquires images around the robot 311 to identify the first alignment mark 141 and the second alignment mark, etc.

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

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

[0077] Correspondingly, fixing members 2115 are also provided at both ends of the U-shaped second fixing frame, and the fixing members 2115 are also electromagnetic mechanisms.

[0078] As an embodiment, the calibration mechanism 340 is a square flat plate, which is used to calibrate the camera. Specifically, when testing the mobile phone camera, first take a picture of the square flat plate, observe the position of the flat plate image, and the distance between the flat plate image and the periphery of the picture, and compare the difference between the images taken by the cameras of other models of mobile phones, so as to make corresponding adjustments, 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 facilitate the detection of the camera's shooting performance. Preferably, because the area of ​​the machine is limited, the flat plate is supported to a certain height by the legs, and the flat plate protrudes from the surrounding components to facilitate image recognition.

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