[0062] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0063] The following is for reference. Figures 1-5 The end effector 100 provided in the embodiments of this application is described. The end effector 100 includes a base 110, a tooling 120 and a floating mechanism 130.

[0064] The tooling component 120 is used to connect to the mating component 10, which is adapted to be inserted into the test piece 20 to form an electrical circuit. The floating mechanism 130 is used to adjust the tooling component 120 to float relative to the base 110 along a first direction. The floating mechanism 130 includes a mounting base 131, an elastic element 132, and a connecting element 133. The mounting base 131 is connected to the base 110. The elastic element 132 is connected to both the mounting base 131 and the connecting element 133. One end of the connecting element 133 is connected to the tooling component 120, and the other end of the connecting element 133 slides through the mounting base 131 along the first direction. The connection method between the tooling component 120 and the mating component 10 includes, but is not limited to, threaded connection, snap-fit, or plug-in connection. The elastic element 132 includes, but is not limited to, a spring.

[0065] It should be noted that the test piece 20 includes, but is not limited to, an electronic screen.

[0066] Understandably, the tooling 120 can drive the mating part 10 to approach the test piece 20 along the first direction until it is inserted into the test piece 20, so that the display effect of the test piece 20 (including brightness, contrast, color reproduction, etc.) can be observed under power-on conditions, thereby improving the comprehensiveness and accuracy of the test. At the same time, the elastic element 132 connects the mounting base 131 and the tooling 120 respectively. It can not only adjust the position of the tooling 120 relative to the mounting base 131 along the first direction by utilizing the deformation of the elastic element 132, thus buffering and compensating for possible positional deviations during the insertion process and improving the accuracy and efficiency of the insertion; it can also use the rebound of the elastic element 132 to reset after the test, ensuring the reusability and reliability of the floating mechanism 130 and improving the automation and stability of the test process.

[0067] According to the end effector 100 provided in the embodiments of this application, by converting the elastic deformation of the elastic member 132 into the displacement of the tooling member 120 relative to the mounting base 131, the tooling member 120 can be adaptively adjusted to a certain extent according to the position of the test piece 20, thereby improving the accuracy and reliability of the insertion.

[0068] In some embodiments, such as Figure 4As shown, the tooling 120 forms a bearing groove 121, and the mating part 10 is partially disposed within the bearing groove 121 to ensure the stability of the connection between the tooling 120 and the mating part 10. It should be noted that the size and shape of the bearing groove 121 can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0069] In some embodiments, such as Figure 3 As shown, the mounting base 131 forms a receiving groove 1310, and one end of the elastic member 132 is connected to the bottom of the receiving groove 1310; wherein,

[0070] The connector 133 includes a first segment 1331 and a second segment 1332 connected together. The outer diameter of the first segment 1331 is larger than the outer diameter of the second segment 1332. The first segment 1331 is located within the receiving groove 1310 and connected to the other end of the elastic member 132. The second segment 1332 is at least partially slidably engaged with the opening of the receiving groove 1310 and connected to the tooling 120. It should be noted that the size and shape of the receiving groove 1310 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0071] Understandably, the opening of the receiving groove 1310 faces the tooling part 120, thus providing room for the deformation of the elastic element 132 and the sliding of the connecting part 133, reducing the possibility of external interference and extending the service life of the floating mechanism 130. Simultaneously, the outer diameter of the first segment 1331 is larger than the outer diameter of the second segment 1332, and the second segment 1332 slides into the opening of the receiving groove 1310. This not only ensures that the connecting part 133 slides into the receiving groove 1310 under the deformation of the elastic element 132, but also reduces the risk of the connecting part 133 disengaging from the receiving groove 1310, ensuring the reliability of the floating mechanism 130.

[0072] In some embodiments, such as Figure 3 As shown, the connector 133 forms a guide groove 1330 that communicates with the receiving groove 1310, and the elastic member 132 is at least partially disposed within the guide groove 1330. It should be noted that the shape and size of the guide groove 1330 can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0073] Understandably, the connecting member 133 has a guide groove 1330 on the side away from the tooling part 120. The guide groove 1330 is always located within the mounting groove, and the opening of the guide groove 1330 faces the opposite direction to the opening of the mounting groove. That is, both ends of the elastic member 132 are connected to the bottom of the mounting groove and the bottom of the guide groove 1330, respectively. The inner wall of the guide groove 1330 and the inner wall of the mounting groove near its bottom restrict the deformation of the elastic member 132, reducing the possibility of displacement of the elastic member 132 during deformation, thereby improving the stability and reliability of the floating mechanism 130.

[0074] In some embodiments, such as Figure 3 As shown, the guide groove 1330 extends from the first section 1331 to the second section 1332, thereby providing a longer limiting path for the sliding of the connector 133 and making the stress distribution of the elastic element 132 more uniform, thus improving the reliability of the floating mechanism 130.

[0075] In some embodiments, such as Figure 3 As shown, the outer side wall of the first segment 1331 is spaced apart from the inner side wall of the receiving groove 1310. The inner side wall portion of the receiving groove 1310 near the groove opening has a guide surface. The outer diameter of the second segment 1332 gradually decreases at least partially towards the tooling 120. The outer side wall portion of the second segment 1332 slides against the guide surface.

[0076] Understandably, the outer wall of the first segment 1331 is spaced apart from the inner wall of the receiving groove 1310, thereby reducing the friction between the connector 133 and the receiving groove 1310 during sliding, making the connector 133 slide more smoothly and improving the sensitivity of the floating mechanism 130. Simultaneously, at least a portion of the outer radial direction of the second segment 1332 near the first segment 1331 gradually decreases towards the tooling 120; that is, the portion of the second segment 1332 near the first segment 1331 is tapered and slides in cooperation with the guide surface, thereby reducing sliding resistance. This provides guidance during the movement of the tooling 120 along the first direction driven by the connector 133, improving the reliability and motion accuracy of the floating mechanism 130.

[0077] In some embodiments, such as Figure 3 and Figure 4 As shown, the tooling 120 is plugged into the connector 133, which enables quick connection and disassembly between the tooling 120 and the connector 133. This improves the versatility and maintenance efficiency of the end effector 100, while ensuring the stability and reliability of the connection, and better meets the high-efficiency operation requirements of test automation.

[0078] In some embodiments, such as Figure 4 As shown, the tooling 120 forms an insertion hole 122, and the end of the connector 133 away from the mounting base 131 is inserted into the insertion hole 122. Exemplarily, the insertion hole 122 is a stepped hole. It should be noted that the size and shape of the insertion hole 122 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0079] In some embodiments, such as Figure 4As shown, the connector 133 is provided with a first anti-fooling part, and the tooling part 120 is provided with a second anti-fooling part. The first anti-fooling part and the second anti-fooling part are connected in cooperation to ensure that the tooling part 120 can only be connected to the connector 133 in the correct way, so as to ensure the accuracy of the subsequent testing process and improve the assembly efficiency.

[0080] In some embodiments, such as Figure 4 As shown, at least part of the inner wall of the insertion hole 122 includes two oppositely arranged planar segments and two oppositely arranged arcuate segments. The planar segments and arcuate segments are arranged alternately and connected end to end to form a second anti-fooling part. The second segment 1332 forms two oppositely arranged notches 13321 away from the first segment 1331. The inner wall of the notch 13321 forms a first anti-fooling part. That is, at least part of the inner wall of the notch 13321 abuts against the planar segment and the arcuate segment respectively. This can not only reduce the possibility of relative rotation between the connector 133 and the tooling 120, but also correct the insertion direction of the tooling 120, thereby improving the reliability and ease of use of the end effector 100.

[0081] In some embodiments, such as Figure 1 and Figure 4 As shown, the end effector 100 also includes a clamping drive 140 and two opposing clamping members 150. The clamping drive 140 is disposed on the base 110. The clamping members 150 are connected to the clamping drive 140, and the clamping drive 140 is adapted to drive the two clamping members 150 to move closer to each other to clamp the mounting base 131. The clamping drive 140 includes, but is not limited to, a gripper cylinder.

[0082] It is understood that the clamping drive 140 drives the two clamping members 150 to move closer or further apart relative to each other along the second direction, thereby realizing the clamping and releasing function of the floating mechanism 130. The connection method between the clamping members 150 and the clamping drive 140 includes, but is not limited to, threaded connection, snap-fit, or plug-in connection.

[0083] It should be noted that the second direction intersects with the first direction.

[0084] In some embodiments, such as Figure 4 As shown, a first positioning part 151 is provided on one side of the two clamping parts 150 that are close to each other, and a second positioning part 1311 is provided on the mounting base 131. The first positioning part 151 and the second positioning part 1311 correspond to each other and are positioned and engaged.

[0085] It is understandable that the cooperation of the first positioning part 151 and the second positioning part 1311 can ensure that the two clamping parts 150 can accurately clamp the mounting base 131, thereby improving the repeatability and reliability of the end effector 100 and ensuring the accuracy of subsequent tests.

[0086] In some embodiments, such as Figure 4 As shown, one of the first positioning part 151 and the second positioning part 1311 is provided with a groove, and the other of the first positioning part 151 and the second positioning part 1311 is provided with a protrusion that mates with the groove, thereby achieving precise positioning between the mounting base 131 and the clamping member 150. Of course, in other embodiments, accurate positioning between the two can also be achieved by making the first positioning part 151 and the second positioning part 1311 form a contact sensor, and this embodiment does not impose specific limitations on this.

[0087] For example, such as Figure 4 As shown, the first positioning part 151 is provided with a protrusion, and the second positioning part 1311 is provided with a groove. The shape of the protrusion includes, but is not limited to, a hemispherical shape, a semi-cylindrical shape, or a triangle.

[0088] In some embodiments, such as Figure 4 As shown, the protrusion includes a first protrusion and a second protrusion. The first protrusion extends along a first direction and protrudes from the clamping member 150 along a second direction. The second protrusion is sleeved on the outer wall of the first protrusion. The groove includes a first groove and a second groove. The first groove extends along the first direction and is formed in the mounting base 131. The second groove is formed in the groove wall of the first groove and mates with the second protrusion. The first protrusion includes, but is not limited to, a semi-cylindrical shape. The second protrusion includes, but is not limited to, a hemispherical shape.

[0089] It is understandable that the basic positioning and connection between the mounting base 131 and the clamping member 150 are achieved through the sliding fit of the first protrusion and the first groove, and the precise positioning between the mounting base 131 and the clamping member 150 is achieved through the positioning fit of the second protrusion and the second groove, thereby improving the positioning accuracy and structural stability between the clamping member 150 and the mounting base 131.

[0090] In some embodiments, such as Figure 1 As shown, the clamping drive 140 is slidably disposed on the base 110 along the first direction. The end effector 100 also includes a pressure sensor 160, which is disposed between the clamping drive 140 and the base 110 to obtain the pressure during the insertion process of the mating piece 10 and the test piece 20 in real time. The pressure sensor 160 includes, but is not limited to, a strain gauge pressure sensor 160 or a piezoelectric pressure sensor 160.

[0091] Understandably, when the clamping drive 140 moves the docking member 10 closer to the test piece 20, the test piece 20 will exert a reaction force on the docking member 10, causing the clamping drive 140 to move away from the docking member 10 relative to the base 110. This allows the pressure sensor 160, located between the base 110 and the clamping drive 140, to monitor the insertion pressure in real time, ensuring a smooth insertion process between the docking member 10 and the test piece 20, and improving the testing accuracy, stability, and operational safety of the end effector 100.

[0092] In some embodiments, such as Figure 1 As shown, the end effector 100 also includes a guide assembly 170, which is disposed between the clamping drive member 140 and the base 110. This guide assembly 170 reduces insertion errors caused by offset or vibration of the clamping drive member 140, and improves the motion accuracy and stability of the clamping drive member 140. The guide assembly 170 includes a guide rail and a guide block that slide along a first direction. One of the guide rail and the guide block is disposed at the fixed end of the clamping drive member 140, and the other is disposed at the base 110.

[0093] This application also provides a robotic arm.

[0094] like Figure 5 As shown, the robotic arm includes a robotic arm body 200 and the aforementioned end effector 100, with the end effector 100 disposed on the robotic arm body 200. The robotic arm body 200 includes, but is not limited to, Cartesian robots, articulated robots, or parallel robots.

[0095] According to the robot provided in the embodiments of this application, by converting the elastic deformation of the elastic member 132 into the displacement of the tooling part 120 relative to the mounting base 131, the tooling part 120 can be adaptively adjusted to a certain extent according to the position of the test piece 20, thereby improving the accuracy and reliability of the insertion.

[0096] This application also provides a detection device.

[0097] like Figures 5 to 8 As shown, the detection device includes a mounting frame 300, a first visual positioning component 400, a second visual positioning component 500, an imaging structure, and the aforementioned robotic arm.

[0098] The mounting bracket 300 is used to position the test piece 20; the robotic arm is used to connect to the docking member 10 and move it closer to or away from the mounting bracket 300, the docking member 10 being adapted to be inserted into the test piece 20 to form an electrical circuit; the first visual positioning component 400 is disposed on the mounting bracket 300 and located below the test piece 20, and is used at least for visual positioning of the test piece 20; the second visual positioning component 500 is distributed at intervals from the first visual positioning component 400, disposed on the mounting bracket 300 and located below the test piece 20, and is used at least for visual positioning of the docking member 10; the imaging structure is located above the test piece 20 and is used to obtain the detection image of the test piece 20 after it is powered on.

[0099] Understandably, the mounting bracket 300 is used to fix and position the test piece 20, ensuring its stability during testing and reducing potential errors. On one hand, the first visual positioning component 400 determines the position of the test piece 20. On the other hand, when the robotic arm moves the docking piece 10 closer to the mounting bracket 300, the second visual positioning component 500 visually positions the docking piece 10, providing a precise reference for planning the docking piece 10's proximity to the test piece 20 and ensuring accurate insertion of the docking piece 10 into the test piece 20. Furthermore, both the first and second visual positioning components 400 are located below the test piece 20 to reduce interference with the imaging structure and ensure testing accuracy.

[0100] It should be noted that after the docking part 10 and the test piece 20 are connected to form a test circuit, various display signals can be sent to the test piece 20 through a pre-set test program, such as displaying images of different colors, playing videos, or simulating touch operations, and the corresponding detection images can be obtained through the imaging structure to comprehensively detect the various functions of the test piece 20.

[0101] According to the detection device provided in the embodiments of this application, the insertion process between the docking part 10 and the test piece 20 is accurate and error-free through dual visual positioning, thereby reducing detection errors and improving the accuracy and reliability of detection.

[0102] In some embodiments, such as Figure 7 As shown, the first visual positioning component 400 includes a first camera 410 and a first light source 420. The first camera 410 is disposed on the mounting bracket 300; the first light source 420 is disposed on the mounting bracket 300 and is located between the first camera 410 and the test piece 20.

[0103] It is understandable that the test piece 20, the first light source 420, and the first camera 410 are arranged sequentially from top to bottom. That is, the first light source 420 illuminates the part of the test piece 20 used for insertion and mating with the mating piece 10 to enhance the contrast at this point, so that the first camera 410 can more accurately identify the corresponding contour and position and improve the accuracy of visual positioning.

[0104] In some embodiments, such as Figure 7 As shown, the first light source 420 is a strip light source to provide uniform illumination, which can enhance the contour and details of the test piece 20, improve image contrast, and improve positioning accuracy and interlocking efficiency.

[0105] In some embodiments, such as Figure 7 As shown, the first light source 420 is adjustablely mounted on the mounting bracket 300 to adjust its direction and angle, facilitating adaptation to test pieces 20 of different shapes and sizes. This reduces interference from ambient light, further improving the accuracy of visual positioning and enhancing the versatility and flexibility of the testing device. It should be noted that the angle of the first light source 420 relative to the mounting bracket 300 can be adjusted using an angle knob and a locking mechanism; this embodiment does not impose specific limitations on this.

[0106] In this embodiment, as Figure 7 As shown, the first light source 420 extends along the second direction, and the first light source 420 is adjustablely disposed on the mounting bracket 300 along the second axis, the second axis being parallel to the second direction.

[0107] In some embodiments, the first camera 410 is adjustable in position on the mounting bracket 300 along the vertical direction to optimize the viewing angle and focal length of the first camera 410, ensuring that the image of the test piece 20 can be clearly captured, thereby improving the versatility and flexibility of the testing device. It should be noted that the first camera 410 can be moved relative to the mounting bracket 300 in the vertical direction by driving the relative movement between the slider and the slide rail via a motor or manually; this embodiment does not impose specific limitations on this.

[0108] In some embodiments, such as Figure 7 As shown, there are two first light sources 420, and the first camera 410 is located between the two first light sources 420. The arrangement direction of the two first light sources 420 is parallel to the arrangement direction of the first visual positioning component 400 and the second visual positioning component 500.

[0109] It is understandable that, such as Figure 7 As shown, the two first light sources 420 are distributed at intervals along the first direction, providing a more uniform illumination effect and ensuring the accurate positioning of the test piece 20.

[0110] In some embodiments, such as Figure 6 As shown, the second visual positioning component 500 includes a second camera 510 and a second light source 520. The second camera 510 is disposed on the mounting bracket 300; the second light source 520 is disposed on the mounting bracket 300 and located between the first camera 410 and the test piece 20.

[0111] It is understandable that the test piece 20, the second light source 520, and the second camera 510 are arranged sequentially from top to bottom. When the robotic arm drives the docking piece 10 to approach the test piece 20 along the first direction, the second light source 520 illuminates the part of the docking piece 10 used for insertion and mating with the test piece 20 to enhance the contrast at this point. This makes it easier for the second camera 510 to more accurately identify the corresponding contour and position, thereby improving the accuracy of visual positioning.

[0112] In some embodiments, such as Figure 6 As shown, the second light source 520 is a ring light source, which can reduce the shadows caused by the irregular shape or surface of the docking part 10, highlight the edges and details of the docking part 10 as much as possible, and improve the accuracy of positioning the docking part 10.

[0113] In some embodiments, such as Figure 6 As shown, the second camera 510 is adjustable in position on the mounting bracket 300 along the vertical direction to optimize the viewing angle and focal length of the second camera 510, ensuring that the image of the docking part 10 can be clearly captured, thereby improving the versatility and flexibility of the detection device. It should be noted that the second camera 510 can be moved relative to the mounting bracket 300 in the vertical direction by driving the relative movement between the slider and the slide rail via a motor or manually; this embodiment does not impose specific limitations on this.

[0114] In some embodiments, such as Figure 5 As shown, along the vertical direction, the projections of the first camera 410 and the second camera 510 both fall within the projection of the test piece 20.

[0115] It is understandable that the first camera 410 and the second camera 510 are spaced apart along the first direction and located inside the outer wall of the test piece 20. This ensures that the fields of view of the first camera 410 and the second camera 510 can cover the test piece 20, so that the robot arm can always be captured by the cameras (including the first camera 410 and the second camera 510) while moving the docking piece 10 close to the test piece 20. This allows for real-time acquisition of the relevant positional changes between the docking piece 10 and the test piece 20, thereby improving the accuracy and reliability of the detection.

[0116] In some embodiments, such as Figures 5 to 8As shown, the testing device also includes a third visual positioning component 600, which is disposed on the mounting frame 300 and is used to perform visual positioning of the test piece 20 and the mating piece 10 during the insertion process. This allows for visual positioning of the mating piece 10 and the test piece 20 from multiple perspectives, ensuring that the insertion process of the test piece 20 and the mating piece 10 is accurate and error-free, reducing testing errors, improving the accuracy and reliability of testing, and meeting the needs of automated testing.

[0117] In some embodiments, such as Figure 7 As shown, the third visual positioning component 600 includes a third camera 610 and a third light source 620. The third camera 610 is mounted in an adjustable position on the mounting frame 300. The third light source 620 is mounted in an adjustable position on the mounting frame 300 and is located between the third camera 610 and the test piece 20.

[0118] It is understandable that the test piece 20, the third light source 620, and the third camera 610 are arranged along the first direction. During the process of the robotic arm bringing the docking piece 10 closer to the test piece 20 and engaging it, the third light source 620 illuminates the portion of the test piece 20 used for engagement with the docking piece 10 to enhance contrast. This allows the third camera 610 to more accurately identify the corresponding contour and position, improving the accuracy of visual positioning. Furthermore, by adjusting the positions of both the third light source 620 and the third camera 610 on the mounting bracket 300, the positions between the third camera 610 and the third light source 620, as well as between the third light source 620 and the test piece 20, can be adjusted to ensure that images during the engagement process are clearly captured, improving the versatility and flexibility of the testing device.

[0119] In some embodiments, such as Figure 7 As shown, the third light source 620 is adjustablely positioned on the mounting frame 300 along the first direction; the third camera 610 is adjustablely positioned on the mounting frame 300 along the second direction. Of course, in other embodiments, the third camera 610 may also be adjustablely positioned on the mounting frame 300 along the first direction; the third light source 620 may also be adjustablely positioned on the mounting frame 300 along the second direction. This embodiment does not impose specific limitations on this.

[0120] In some embodiments, such as Figure 5 As shown, the third visual positioning component 600 is located outside one side of the test piece 20, and the third visual positioning component 600, the first visual positioning component 400 and the second visual positioning component 500 are spaced apart along the first direction.

[0121] It is understood that the third visual positioning component 600, the first visual positioning component 400, and the second visual positioning component 500 are sequentially distributed along the first direction, and the third visual positioning component 600 is located on the outer side of the test piece 20 along the horizontal direction. Combined with the first visual positioning component 400 and the second visual positioning component 500 being located below the test piece 20, the mating part 10 and the test piece 20 can be visually positioned from multiple aspects, ensuring that the insertion process of the test piece 20 and the mating part 10 is accurate and error-free, reducing detection errors, improving the accuracy and reliability of detection, and meeting the needs of automated detection.

[0122] In some embodiments, such as Figure 5 As shown, the testing device also includes an installation platform 700, on which the mounting frame 300 and the robotic arm are mounted to integrate the testing device, facilitate centralized management and maintenance, reduce operational complexity, and improve space utilization efficiency.
