[0062] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where 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 the present application and should not be construed as a limitation of the present application.

[0063] Reference is made below to Figures 1 - 5 describe the end effector 100 provided by the embodiments of the present application. The end effector 100 includes a base 110, a tooling part 120, and a floating mechanism 130.

[0064] The tooling part 120 is used to connect the docking part 10, and the docking part 10 is adapted to be inserted into the test piece 20 to form an energized circuit; the floating mechanism 130 is used to adjust the tooling part 120 to float relative to the base 110 in the first direction; wherein, the floating mechanism 130 includes a mounting seat 131, an elastic member 132, and a connecting member 133. The mounting seat 131 is connected to the base 110, the elastic member 132 is respectively connected to the mounting seat 131 and the connecting member 133, one end of the connecting member 133 is connected to the tooling part 120, and the other end of the connecting member 133 slides through the mounting seat 131 in the first direction. The connection method between the tooling part 120 and the docking part 10 includes but is not limited to threaded connection, snap connection, or plug connection, etc. The elastic member 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] It can be understood that after the tooling part 120 drives the docking part 10 to approach the test piece 20 in the first direction until it is inserted into the test piece 20, the display effect of the test piece 20 (including brightness, contrast, color reproducibility, etc.) can be observed under the energized state, so as to improve the comprehensiveness and accuracy of the detection. At the same time, by connecting the mounting seat 131 and the tooling part 120 with the elastic member 132 respectively, not only can the deformation of the elastic member 132 be used to adjust the position of the tooling part 120 relative to the mounting seat 131 in the first direction, play a role in buffering and compensating for possible position deviations during the insertion process, and improve the accuracy and efficiency of the insertion; but also the elastic return of the elastic member 132 can be used to play a reset role after the test, ensuring the reusability and reliability of the floating mechanism 130, and improving the automation degree and stability of the test process.

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

[0068] In some embodiments, such as Figure 4As shown, the tooling part 120 forms a bearing groove 121, and a part of the docking part 10 is arranged in the bearing groove 121 to ensure the stability of the connection between the tooling part 120 and the docking 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 make specific limitations in this regard.

[0069] In some embodiments, as Figure 3 shown, the mounting seat 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 connecting member 133 includes a first section 1331 and a second section 1332 connected to each other. The outer diameter of the first section 1331 is larger than that of the second section 1332. The first section 1331 is located in the receiving groove 1310 and is connected to the other end of the elastic member 132, and the second section 1332 is at least partially in sliding fit with the notch of the receiving groove 1310 and is connected to the tooling part 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 make specific limitations in this regard.

[0071] It can be understood that the notch of the receiving groove 1310 faces the tooling part 120, thereby providing a moving space for the deformation of the elastic member 132 and the sliding of the connecting member 133, and also reducing the possibility of external interference and prolonging the service life of the floating mechanism 130. At the same time, the outer diameter of the first section 1331 is larger than that of the second section 1332 and the second section 1332 is in sliding fit with the notch of the receiving groove 1310, which can not only ensure that the connecting member 133 slides in cooperation with the receiving groove 1310 under the action of the deformation of the elastic member 132, but also reduce the risk of the connecting member 133 disengaging from the receiving groove 1310 and ensure the reliability of the operation of the floating mechanism 130.

[0072] In some embodiments, as Figure 3 shown, the connecting member 133 forms a guiding groove 1330 communicating with the receiving groove 1310, and the elastic member 132 is at least partially arranged in the guiding groove 1330. It should be noted that the shape and size of the guiding groove 1330 can be designed according to actual needs, and this embodiment does not make specific limitations in this regard.

[0073] It can be understood that a guiding groove 1330 is formed on the side of the connecting member 133 away from the tooling part 120. The guiding groove 1330 is always located in the installation groove, and the notch orientation of the guiding groove 1330 is opposite to that of the installation groove. That is, the two ends of the elastic member 132 are respectively connected to the bottom of the installation groove and the bottom of the guiding groove 1330. The inner wall of the guiding groove 1330 and the inner wall of the installation groove near its bottom play a role in restricting the deformation of the elastic member 132, reducing the possibility of deviation during the deformation of the elastic member 132, thereby improving the stability and reliability of the floating mechanism 130.

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

[0075] In some embodiments, as Figure 3 shown, the outer sidewall of the first section 1331 is spaced apart from the inner sidewall of the receiving groove 1310. The inner sidewall portion of the receiving groove 1310 near the notch has a guiding surface. The outer diameter of the second section 1332 gradually decreases at least partially in the direction approaching the tooling part 120, and the outer sidewall portion of the second section 1332 is in sliding contact with the guiding surface.

[0076] It can be understood that the outer sidewall of the first section 1331 is spaced apart from the inner sidewall of the receiving groove 1310, so as to reduce the friction between the connecting member 133 and the receiving groove 1310 during sliding, making the connecting member 133 slide more smoothly and improving the sensitivity of the floating mechanism 130. At the same time, at least part of the outer diameter of the second section 1332 near the first section 1331 gradually decreases in the direction approaching the tooling part 120, that is, the part of the second section 1332 near the first section 1331 is conical and is in sliding fit with the guiding surface, so as to reduce the sliding resistance and play a guiding role in the process of the connecting member 133 driving the tooling part 120 to move in the first direction, improving the reliability and motion accuracy of the floating mechanism 130.

[0077] In some embodiments, as Figure 3 and Figure 4 shown, the tooling part 120 is inserted into the connecting member 133, realizing the quick connection and disassembly between the tooling part 120 and the connecting member 133, improving the versatility and maintenance efficiency of the end effector 100, and at the same time ensuring the stability and reliability of the connection, and being able to better meet the high-efficiency operation requirements of test automation.

[0078] In some embodiments, as Figure 4 shown, the tooling part 120 forms a jack 122, and one end of the connecting member 133 away from the mounting seat 131 is inserted into the jack 122. Exemplarily, the jack 122 is a stepped hole. It should be noted that the size and shape of the jack 122 can be designed according to actual needs, and this embodiment does not make specific limitations on this.

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

[0080] In some embodiments, as Figure 4 shown, at least a part of the inner wall of the jack 122 includes two oppositely arranged flat sections and two oppositely arranged arc sections. The flat sections and the arc sections are arranged alternately and connected end to end to form the second anti-fooling portion; two oppositely arranged notches 13321 are formed by the second section 1332 away from the first section 1331, and the inner walls of the notches 13321 form the first anti-fooling portion, that is, the inner walls of the notches 13321 are at least partially abutted against the flat sections and the arc sections respectively, which can not only reduce the possibility of relative rotation between the connecting member 133 and the tooling member 120, but also correct the insertion direction of the tooling member 120, and improve the reliability and usability of the end effector 100.

[0081] In some embodiments, as Figure 1 and Figure 4 shown, the end effector 100 further includes a clamping driving member 140 and two oppositely arranged clamping members 150. The clamping driving member 140 is disposed on the base 110; the clamping members 150 are connected to the clamping driving member 140, and the clamping driving member 140 is adapted to drive the two clamping members 150 to approach each other to clamp the mounting seat 131. The clamping driving member 140 includes, but is not limited to, a jaw cylinder.

[0082] It can be understood that the clamping driving member 140 drives the two clamping members 150 to relatively approach or separate along the second direction, so as to realize the clamping and releasing functions of the floating mechanism 130. The connection manner between the clamping member 150 and the clamping driving member 140 includes, but is not limited to, threaded connection, snap connection or plug connection, etc.

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

[0084] In some embodiments, as Figure 4 shown, a first positioning portion 151 is provided on one side where the two clamping members 150 approach each other, and a second positioning portion 1311 is provided on the mounting seat 131. The first positioning portion 151 and the second positioning portion 1311 correspond to each other and are in positioning cooperation.

[0085] It can be understood that through the cooperation of the first positioning portion 151 and the second positioning portion 1311, it can be ensured that the two clamping members 150 can accurately clamp the mounting seat 131, improving the repeatability and reliability of the use of the end effector 100, so as to ensure the accuracy of the subsequent testing.

[0086] In some embodiments, asFigure 4 As shown, one of the first positioning portion 151 and the second positioning portion 1311 is provided with a groove, and the other of the first positioning portion 151 and the second positioning portion 1311 is provided with a protrusion that cooperates with the groove to achieve precise positioning between the mounting base 131 and the clamping member 150. Of course, in other embodiments, the positioning between the two can also be accurately achieved by forming a contact sensor with the first positioning portion 151 and the second positioning portion 1311, and this embodiment does not make specific limitations in this regard.

[0087] Exemplarily, as Figure 4 shown, the first positioning portion 151 is provided with a protrusion, and the second positioning portion 1311 is provided with a groove. The shape of the protrusion includes but is not limited to a hemispherical shape, a semi-cylindrical shape, a triangular shape, etc.

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

[0089] It can be understood 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 convex body 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 convex body and the second groove, improving the positioning accuracy and structural stability between the clamping member 150 and the mounting base 131.

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

[0091] It can be understood that when the clamping driving member 140 drives the docking member 10 close to the test piece 20 to be tested, the test piece 20 to be tested will exert a reaction force on the docking member 10 to drive the clamping driving member 140 to move relative to the base 110 in a direction away from the docking member 10, so that the pressure sensor 160 provided between the base 110 and the clamping driving member 140 can monitor the magnitude of the insertion pressure in real time, ensuring the smooth progress of the insertion process of the docking member 10 and the test piece 20 to be tested, and improving the test accuracy, stability and operation safety of the end effector 100.

[0092] In some embodiments, as Figure 1 shown, the end effector 100 further includes a guiding assembly 170. The guiding assembly 170 is disposed between the clamping driving member 140 and the base 110, reducing the insertion error caused by the offset or vibration of the clamping driving member 140, and improving the motion accuracy and stability of the clamping driving member 140. The guiding assembly 170 includes a guide rail and a guide block that are slidably engaged in a first direction. One of the guide rail and the guide block is disposed at the fixed end of the clamping driving member 140, and the other of the guide rail and the guide block is disposed at the base 110.

[0093] The embodiment of the present application also provides a manipulator.

[0094] As Figure 5 shown, the manipulator includes a manipulator body 200 and the above-mentioned end effector 100. The end effector 100 is disposed on the manipulator body 200. The manipulator body 200 includes, but is not limited to, a Cartesian robot, an articulated robot, a parallel robot, etc.

[0095] According to the manipulator provided by the embodiment of the present application, by converting the elastic deformation of the elastic member 132 into the displacement of the tooling member 120 relative to the mounting seat 131, the tooling member 120 can be adaptively adjusted to a certain extent according to the position of the test piece 20 to be tested, improving the accuracy and reliability of the insertion.

[0096] The embodiment of the present application also provides a detection device.

[0097] As Figures 5 - 8 shown, the detection device includes a mounting frame 300, a first vision positioning assembly 400, a second vision positioning assembly 500, an imaging structure, and the above-mentioned manipulator.

[0098] The mounting bracket 300 is used to position the test piece 20 to be tested; the manipulator is used to connect the docking member 10 and approach or move away from the mounting bracket 300, and the docking member 10 is adapted to be inserted into the test piece 20 to form an energized circuit; the first vision positioning assembly 400 is disposed on the mounting bracket 300 and below the test piece 20 to at least perform vision positioning on the test piece 20; the second vision positioning assembly 500 is spaced apart from the first vision positioning assembly 400, disposed on the mounting bracket 300 and below the test piece 20 to at least perform vision positioning on the docking member 10; the imaging structure is located above the test piece 20 to obtain a detection image after the test piece 20 is energized.

[0099] It can be understood that the mounting bracket 300 is used to fix and position the test piece 20 to be tested, ensuring that the test piece 20 remains stable during the detection process and reducing the possibility of detection errors. On the one hand, the first vision positioning assembly 400 is used to determine the position of the test piece 20. On the other hand, when the manipulator drives the docking member 10 to approach the mounting bracket 300, the second vision positioning assembly 500 performs vision positioning on the position of the docking member 10, thereby providing an accurate reference for planning the approach of the docking member 10 to the test piece 20 and ensuring that the docking member 10 can be accurately inserted into the test piece 20. In addition, both the first vision positioning assembly 400 and the second vision positioning assembly 500 are located below the test piece 20 to reduce interference with the imaging structure and ensure the accuracy of the test.

[0100] It should be noted that after the docking member 10 and the test piece 20 are inserted 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, etc., and the corresponding detection images are obtained through the imaging structure to comprehensively detect various functions of the test piece 20.

[0101] According to the detection device provided by the embodiment of the present application, through dual vision positioning, it is ensured that the insertion process of the docking member 10 and the test piece 20 is accurate and error-free, reducing detection errors and improving the accuracy and reliability of detection.

[0102] In some embodiments, as Figure 7 shown, the first vision positioning assembly 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 between the first camera 410 and the test piece 20.

[0103] It can be understood that the test piece 20, the first light source 420, and the first camera 410 are sequentially arranged from top to bottom. That is, the first light source 420 illuminates the part of the test piece 20 for plugging and mating with the docking piece 10 to enhance the contrast here, so that the first camera 410 can more accurately identify the corresponding contour and position, improving the accuracy of visual positioning.

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

[0105] In some embodiments, as Figure 7 shown, the first light source 420 is adjustably arranged on the mounting bracket 300 at an angle to adjust the direction and angle of the first light source 420, facilitating adaptation to test pieces 20 of different shapes and sizes, reducing the interference of ambient light, further improving the accuracy of visual positioning, and improving the versatility and flexibility of the detection device. It should be noted that the first light source 420 can use the cooperation of an angle knob and a locking member to realize the angle adjustment of the first light source 420 relative to the mounting bracket 300, and this embodiment does not make specific limitations on this.

[0106] In this embodiment, as Figure 7 shown, the first light source 420 extends along the second direction, and the first light source 420 is adjustably arranged on the mounting bracket 300 at an angle along the second axis, and the second axis is parallel to the second direction.

[0107] In some embodiments, the first camera 410 is arranged on the mounting bracket 300 with an adjustable mounting position along the up and down direction to optimize the viewing angle and focal length of the first camera 410, ensure that the image of the test piece 20 can be clearly captured, and improve the versatility and flexibility of the detection device. It should be noted that the first camera 410 can drive the relative movement between the slider and the slide rail by means of a motor or manually to realize the movement of the first camera 410 relative to the mounting bracket 300 along the up and down direction, and this embodiment does not make specific limitations on this.

[0108] In some embodiments, as Figure 7 shown, two first light sources 420 are provided, the first camera 410 is located between the two first light sources 420, and 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 can be understood that, as Figure 7 shown, the two first light sources 420 are spaced apart along the first direction, providing a more uniform illumination effect and ensuring the precise positioning of the test piece 20.

[0110] In some embodiments, as Figure 6 shown, the second vision 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 is located between the first camera 410 and the test piece 20.

[0111] It can be understood that the test piece 20, the second light source 520, and the second camera 510 are arranged in sequence from top to bottom. That is, when the manipulator drives the docking member 10 to approach the test piece 20 along the first direction, the second light source 520 illuminates the portion of the docking member 10 for plugging and mating with the test piece 20 to enhance the contrast here, so that the second camera 510 can more accurately identify the corresponding contour and position, improving the accuracy of vision positioning.

[0112] In some embodiments, as Figure 6 shown, the second light source 520 is an annular light source, which can reduce the shadows generated due to the shape or surface irregularity of the docking member 10, highlight the edges and details of the docking member 10 as much as possible, and improve the accuracy of positioning the docking member 10.

[0113] In some embodiments, as Figure 6 shown, the second camera 510 is disposed on the mounting bracket 300 with its installation position adjustable in the up-down direction to optimize the viewing angle and focal length of the second camera 510, ensure that the image of the docking member 10 can be clearly captured, and improve the versatility and flexibility of the detection device. It should be noted that the second camera 510 can drive the relative movement between the slider and the slide rail by means of a motor or manually to realize the movement of the second camera 510 relative to the mounting bracket 300 in the up-down direction. This embodiment does not make specific limitations on this.

[0114] In some embodiments, as Figure 5 shown, in the up-down 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 can be understood that the first camera 410 and the second camera 510 are arranged at intervals along the first direction and are located inside the outer side wall of the test piece 20, which can ensure that the fields of view of the first camera 410 and the second camera 510 can both cover the test piece 20, facilitating that the docking member 10 can always be captured by the cameras (including the first camera 410 and the second camera 510) during the process of the manipulator driving the docking member 10 to approach the test piece 20, so as to obtain the relevant position changes between the docking member 10 and the test piece 20 in real time, improving the accuracy and reliability of detection.

[0116] In some embodiments, as Figures 5 - 8As shown, the detection device further includes a third vision positioning component 600. The third vision positioning component 600 is disposed on the mounting bracket 300 and is used for visually positioning the process of inserting the test piece 20 into the docking piece 10, so as to perform visual positioning on the docking piece 10 and the test piece 20 from multiple aspects, ensure the accuracy of the insertion process of the test piece 20 and the docking piece 10, reduce detection errors, improve the accuracy and reliability of detection, and meet the requirements of automatic detection.

[0117] In some embodiments, as Figure 7 shown, the third vision positioning component 600 includes a third camera 610 and a third light source 620. The third camera 610 is disposed on the mounting bracket 300 with an adjustable mounting position; the third light source 620 is disposed on the mounting bracket 300 with an adjustable mounting position and is located between the third camera 610 and the test piece 20.

[0118] It can be understood that the test piece 20, the third light source 620, and the third camera 610 are arranged along the first direction. That is, during the process of the manipulator driving the docking piece 10 to approach the test piece 20 and insert it thereinto, the third light source 620 illuminates the part of the test piece 20 for inserting and mating with the docking piece 10 to enhance the contrast here, so as to facilitate the third camera 610 to more accurately identify the corresponding contour and position and improve the accuracy of visual positioning. In addition, by both the third light source 620 and the third camera 610 being disposed on the mounting bracket 300 with adjustable mounting positions, the positions between the third camera 610 and the third light source 620 and the positions between the third light source 620 and the test piece 20 are adjusted to ensure that the images during their insertion process can be clearly captured, improving the versatility and flexibility of the detection device.

[0119] In some embodiments, as Figure 7 shown, the third light source 620 is disposed on the mounting bracket 300 with an adjustable position along the first direction; the third camera 610 is disposed on the mounting bracket 300 with an adjustable position along the second direction. Of course, in other embodiments, the third camera 610 can also be disposed on the mounting bracket 300 with an adjustable position along the first direction; the third light source 620 can also be disposed on the mounting bracket 300 with an adjustable position along the second direction. This embodiment does not make specific limitations on this.

[0120] In some embodiments, as Figure 5 shown, the third vision positioning component 600 is located outside one side of the test piece 20, and the third vision positioning component 600, the first vision positioning component 400, and the second vision positioning component 500 are arranged at intervals along the first direction.

[0121] It can be understood that the third vision positioning component 600, the first vision positioning component 400, and the second vision positioning component 500 are sequentially distributed along the first direction. The third vision positioning component 600 is located outside the test piece 20 along the horizontal direction, and in combination with the first vision positioning component 400 and the second vision positioning component 500 being located below the test piece 20, visual positioning of the docking component 10 and the test piece 20 can be performed from multiple aspects, ensuring the accurate insertion process of the test piece 20 and the docking component 10, reducing detection errors, improving the accuracy and reliability of detection, and meeting the requirements of automated detection.

[0122] In some embodiments, as Figure 5 shown, the detection device further includes a mounting platform 700. The mounting frame 300 and the manipulator are both disposed on the mounting platform 700 to integrate the detection device, facilitate centralized management and maintenance, reduce the complexity of operation, and improve the space utilization efficiency.
