[0050] Please refer toFigures 1-5 , this embodiment provides a robot arm 100, the robot arm 100 includes a main frame 110, a movable support 120, a first driving unit 130, a clamping unit 140 and a detection sensor 150;

[0051] The movable bracket 120 is movably connected to the main frame 110 along a first preset direction, and the first driving unit 130 is transmission-connected to the movable bracket 120 to drive the movable bracket 120 to move relative to the main frame 110 along the first preset direction;

[0052] The clamping unit 140 is connected to the movable bracket 120 , and is used to clamp or release the material; the detection sensor 150 is connected to the clamping unit 140 , and is used to detect whether the clamping unit 140 clamps the material.

[0053] It should be noted that this embodiment is explained by taking the application of the robot arm 100 in an automatic testing system for testing SSD10 as an example, and its purpose is to clamp, release, insert and transport SSD10 in the automatic testing system, so as to improve the testing efficiency of SSD10 and reduce the number of times SSD10 is manually picked up, thereby reducing human damage to SSD10; in addition, in other embodiments of the present invention, the robot arm 100 can also be applied to actions such as clamping, releasing, inserting and transporting other types of materials.

[0054] Please refer to Figures 1-5 , the working principle of the robot arm 100 is:

[0055] The robot arm 100 includes a main frame 110, a movable support 120, a first driving unit 130, a clamping unit 140 and a detection sensor 150;

[0056] The movable bracket 120 is movably connected to the main frame 110 along a first preset direction, and the first driving unit 130 is transmission-connected to the movable bracket 120 to drive the movable bracket 120 to move relative to the main frame 110 along the first preset direction; the clamping unit 140 is connected to the movable bracket 120, and the clamping unit 140 is used to clamp or release the material;

[0057] Thus, the robot arm 100 can clamp or release the SSD 10 through the clamping unit 140, and after clamping the SSD 10, the movable bracket 120 can be moved relative to the main frame 110 to drive the clamped SSD 10 to change its position in space, so as to transfer the SSD 10, and then the SSD 10 insertion action can be completed by changing its position in space, so as to improve the efficiency of SSD 10 production and detection;

[0058] As can be seen from the above, by setting the robotic arm 100, the SSD 10 can be clamped by the clamping unit 140 and the position thereof can be changed in space, so that in this way, the number of times of manually taking the SSD 10 in each link of production and testing of the SSD 10 can be reduced, and thus the artificial damage rate of the SSD 10 can be reduced;

[0059] Moreover, in the production and testing links, by setting the robotic arm 100, the dependence on manual labor can be reduced, the production and testing efficiency can be improved, and the requirement for the space area can be reduced, so that the production and testing costs of the SSD 10 can be reduced;

[0060] In addition, a detection sensor 150 is connected to the clamping unit 140. Through the detection sensor 150, it can be detected whether the clamping unit 140 clamps a material, and then the clamping state of the SSD 10 can be detected, so that the clamping accuracy can be improved to improve the testing accuracy and avoid misoperation;

[0061] In summary, the robotic arm 100 can be applied to an automatic testing system, which can assist in the transfer of the SSD 10 and the detection of the SSD 10, and thus can reduce the artificial damage rate of the SSD 10, improve the production efficiency and detection efficiency of the SSD 10, reduce the labor intensity of workers, reduce the labor cost, and further reduce the production and testing costs of the SSD 10.

[0062] Furthermore, please refer to Figures 1-6 , in this embodiment, when configuring the clamping unit 140, its function is to clamp and release the SSD 10. Therefore, the clamping unit 140 may include a first clamping body 141, a second clamping body 142 and a second driving unit 143;

[0063] Both the first clamping body 141 and the second clamping body 142 are movably connected to the movable bracket 120, so as to move in the direction of approaching each other to clamp the material or move in the direction of moving away from each other to release the material under the driving action of the second driving unit 143;

[0064] Wherein, the detection sensor 150 is connected to the first clamping body 141 or the second clamping body 142.

[0065] Through the above structural setting, the second driving unit 143 can drive the first clamping body 141 and the second clamping body 142 to move relative to the movable bracket 120, and thus the clamping or releasing of the SSD 10 can be completed;

[0066] It should be noted that when configuring the second driving unit 143, the second driving unit 143 drives the first clamp 141 and the second clamp 142 to move synchronously relative to the movable bracket 120, so that when clamping or releasing the SSD10, the relative position of the SSD10 remains unchanged, so that the relative displacement of the SSD10 caused by the movement of one of the first clamp 141 and the second clamp 142 can be avoided, and the damage rate of the SSD10 can be reduced. In other embodiments of the utility model, when configuring the above-mentioned second driving unit 143, the movement of the first clamp 141 and the second clamp 142 can be set according to the type of material to be clamped, so that the second driving unit 143 can drive one of them to move.

[0067] It should also be noted that when clamping SSD10, in order to avoid damage to SSD10 during the clamping process, the parts of the first clamp 141 and the second clamp 142 that are used to contact SSD10 are configured with soft materials or other structures to protect SSD10 during the clamping process and avoid damage to SSD10. For example, structures such as silicone flexible pads can be set.

[0068] For further information, please refer to Figures 1-9 In this embodiment, it can be known from the above contents that the robot arm 100 can also complete the insertion of the SSD 10 during use, and its purpose is to insert it into the testing station or the box loading station. Therefore, on the basis of the above-mentioned first driving unit 130, the clamping unit 140 can also include a third driving unit 144 and a rotating shaft 145; the rotating shaft 145 is rotatably connected to the movable bracket 120, and the third driving unit 144 is in transmission connection with the rotating shaft 145 to drive the rotating shaft 145 to rotate relative to the movable bracket 120;

[0069] The first clamping body 141 includes a first main body 1411 and a first clamping head 1412, and the first clamping head 1412 is rotatably connected to the first main body 1411; the second clamping body 142 includes a second main body 1421 and a second clamping head 1422, and the second clamping head 1422 is rotatably connected to the second main body 1421;

[0070] The rotating shaft 145 extends along the moving direction of the first clamp body 141 and the second clamp body 142, and the first clamp head 1412 and the second clamp head 1422 are transmission connected to the rotating shaft 145, so that the third driving unit 144 can drive the first clamp head 1412 and the second clamp head 1422 to rotate synchronously around the axis of the rotating shaft 145 through the rotating shaft 145.

[0071] With the above structural arrangement, the third driving unit 144 can drive the rotating shaft 145 to rotate. On this basis, the first chuck 1412 and the second chuck 1422 can be driven to rotate synchronously, so as to adjust the angles of the first chuck 1412 and the second chuck 1422, and the SSD 10 clamped by the first chuck 1412 and the second chuck 1422 relative to the movable bracket 120, facilitating the corresponding insertion action of the SSD 10. It should be noted that the first chuck 1412 and the second chuck 1422 are in transmission connection with the rotating shaft 145, and the rotating shaft 145 is constrained and fixed by a rotating shaft bracket. This structural design can improve the stability of the clamping pieces on the first chuck 1412 and the second chuck 1422 during the process of clamping the SSD. Based on the structures of the first driving unit 130 and the second driving unit 143, the second driving unit 143 can complete the clamping and releasing of the SSD 10, while the first driving unit 130 and the third driving unit 144 can complete the spatial position transformation and socket of the SSD 10. In addition, in the above content, the first driving unit 130 is used to drive the movement of the movable bracket 120. Therefore, it can adopt a telescopic structure, such as a motor-driven telescopic rod, a hydraulic cylinder or a pneumatic cylinder; while the second driving unit 143 is used to drive the first clamping body 141 and the second clamping body 142 to approach or move away from each other. Therefore, it can adopt a motor-driven threaded lead screw structure or the aforementioned telescopic structure; and the third driving unit 144 is used to drive the first chuck 1412 and the second chuck 1422 to rotate. Therefore, it can adopt a direct motor drive structure or a motor structure with a belt drive structure. It should be noted that the aforementioned structural arrangement is only a part of the structure for achieving the aforementioned purpose, and other structures will not be elaborated here.

[0072] Further, please refer to Figures 1-9 , in this embodiment, as can be seen from the foregoing content, when the third driving unit 144 drives the first chuck 1412 and the second chuck 1422 to rotate, the rotation of the rotating shaft 145 will not drive the movement of the first main body 1411 and the second main body 1421. Therefore, through holes for the rotating shaft 145 to pass through are provided in the first main body 1411 and the second main body 1421; or, the first main body 1411 and the second main body 1421 are rotatably connected to the rotating shaft 145 through bearings.

[0073] On this basis, in order to enable the rotation of the rotating shaft 145 to drive the first clamp 1412 and the second clamp 1422 to rotate, the clamping unit 140 further includes a first clamping block 1413 connected to the first clamp 1412 and a second clamping block 1423 connected to the second clamp 1422; the first clamping block 1413 and the second clamping block 1423 are both clamped to the rotating shaft 145. Specifically, in order to enable the rotation of the rotating shaft 145 to drive the first clamp 1412 and the second clamp 1422 to rotate through the first clamping block 1413 and the second clamping block 1423, a clamping plane can be configured on the outer periphery of the rotating shaft 145, and the first clamping block 1413 and the second clamping block 1423 can be configured with a clamping groove matched with the clamping plane; and in other embodiments of the utility model, a structure such as a pin can also be configured so that the rotating shaft 145 can drive the first clamp 1412 and the second clamp 1422 to rotate.

[0074] On the basis of the above structure, when configuring the detection sensor 150, please refer to Figures 1-10 This embodiment adopts the setting mode of optical fiber sensor, and in order to improve its detection accuracy, the detection sensor 150 is connected to the first clamp 1412 or the second clamp 1422. In addition, in order to improve the stability of clamping, the clamping unit 140 also includes a first clamp 1414 and a second clamp 1424; the first clamp 1414 and the second clamp 1424 can adapt to the clamping work of SSD10, and can also adapt to different types of SSD10 or different materials by replacing the first clamp 1414 and the second clamp 1424; in addition, the third driving unit 144 is connected to the rotating shaft 145, so that the rotating shaft 145 can be driven by the third driving unit 144 relative to the movable bracket 1 20 rotates, thereby driving the rotation of the first clamp 1414 and the second clamp 1424. Based on this, the third drive unit 144 can be set as a high-precision servo motor for rotation control, thereby ensuring the reliability of SSD insertion and removal; the opening and closing of the first clamp 1414 and the second clamp 1424 can also be controlled by high precision, thereby ensuring the reliability of SSD clamping and placement; in summary, this structural design and control scheme design can improve the stability and reliability of the clamp in clamping and placing SSDs, thereby ensuring the core functions of the manipulator.

[0075] When configuring the first clamping piece 1414 and the second clamping piece 1424, in order to improve their fitting degree with the side surface of the SSD 10 when clamping the SSD 10 and to avoid damaging the SSD 10 when clamping it, therefore, the first clamping piece 1414 and the second clamping piece 1424 are both provided with hollow holes 1415. The hollow holes 1415 are used to divide the areas of the first clamping piece 1414 and the second clamping piece 1424 for clamping the material into a first clamping area 1416 and a second clamping area 1417. This setting method aims to make the positions where the first clamping piece 1414 and the second clamping piece 1424 contact the SSD 10 when clamping the SSD 10 be distributed around the SSD 10. Since positioning grooves 1418 for cooperating with the material are provided in both the first clamping area 1416 and the second clamping area 1417, the fitting degree can be improved, thereby improving the clamping stability and avoiding damage to the SSD 10.

[0076] On this basis, in order to avoid interference between the installation of the first clamping piece 1414 and the second clamping piece 1424 and the detection sensor 150, therefore, the first clamping piece 1414 is connected to one end of the first chuck 1412 away from the first main body 1411, and the second clamping piece 1424 is connected to one end of the second chuck 1422 away from the second main body 1421; the detection sensor 150 is connected to the first chuck 1412 and is spaced from the first clamping piece 1414; or, the detection sensor 150 is connected to the second chuck 1422 and is spaced from the second clamping piece 1424.

[0077] Furthermore, as can be seen from the foregoing, during the operation of the robotic arm 100, it can drive the SSD 10 to change its position in space. Based on this, in order to confirm the environment outside the robotic arm 100 during operation, confirm the SSD 10 to be clamped, or confirm the detection environment and insertion environment of the SSD 10, therefore, the robotic arm 100 further includes an image acquisition unit. The image acquisition unit is connected to the main frame 110, and the image acquisition unit is used to acquire images of the material clamping area or the material release area, thereby improving the accuracy during the production and testing of the SSD 10. It should be noted that when configuring the image acquisition unit, multiple image collectors can be configured to acquire multiple sets of image data or perform different image recognition tasks during use. In this embodiment, two image collectors are configured, namely the first image acquisition unit 160 and the second image acquisition unit. Both the first image acquisition unit 160 and the second image acquisition unit 170 are connected to the main frame 110, and the first image acquisition unit 160 and the second image acquisition unit 170 are respectively used to acquire images of the material clamping area and the material release area. It should be noted that when configuring the foregoing image acquisition units, such as the first image acquisition unit 160 and the second image acquisition unit 170, the first image acquisition unit 160 and the second image acquisition unit 170 can be equipped with camera AI vision functions. Such a design makes the structural design more integrated. After the visual inspection process is completed, the robotic hand can immediately perform corresponding clamping and other functions, reducing the waiting time and thus improving the working efficiency of the robotic hand.

[0078] Based on the above robotic arm 100, please refer to Figures 1-10 , this embodiment further provides an automatic testing system. The automatic testing system includes a testing platform, a driving component, and the above-mentioned robotic arm 100; the driving component is connected to the main frame 110, and the driving component is used to drive the main frame 110 to move relative to the testing platform along at least one of a first preset direction, a second preset direction, and a third preset direction; wherein, the first preset direction, the second preset direction, and the third preset direction are perpendicular to each other in pairs.

[0079] In summary, by adopting the above-mentioned robotic arm 100 in the automatic testing system, the driving component can be combined with the first driving unit 130, the second driving unit 143, and the third driving unit 144 in the robotic arm 100, so as to improve the production and testing efficiency of the SSD 10, reduce the artificial damage rate of the SSD 10, reduce the labor intensity of workers, reduce labor costs, and further reduce the production and testing costs of the SSD 10.
