For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0085] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0086] like Figure 1-Figure 8 As shown, an embodiment of the present application provides a positioning device 4, which includes a carrier platform 44, a first positioning mechanism 40 and a second positioning mechanism 42. The carrier platform 44 is provided with a carrier position for placing a workpiece (for example, a mobile phone frame, etc.), that is, the workpiece is placed at the carrier position of the carrier platform 44; the first positioning mechanism 40 is arranged on the carrier platform 44 corresponding to the carrier position, and is used to push the workpiece in the first direction and the second direction in the horizontal plane, respectively, so that the workpiece is accurately placed at the target position, thereby improving the positioning accuracy of the workpiece; the second positioning mechanism 42 is arranged on the carrier platform 44 corresponding to the carrier position, and the second positioning mechanism 42 includes a movable rod 420, a clamping member 422 and a guide pin 424; the movable rod 420 is movably inserted into the carrier platform 44, and the clamping member 422 is arranged so that the movable rod 420 faces the carrier platform. At one end of the load position, the clamping member 422 increases or decreases the vertical distance with the workpiece as the movable rod 420 passes through the supporting platform 44, so as to clamp or loosen the workpiece; the side wall of the movable rod 420 is provided with a spiral groove 4200, and the guide pin 424 is fixedly connected to the supporting platform 44. The guide pin 424 and the spiral groove 4200 are slidably matched to make the movable rod 420 rotate when passing through the supporting platform 44, so as to drive the clamping member 422 toward the workpiece or avoid the workpiece, which can not only ensure the reliable clamping of the workpiece and improve the uniformity of the mobile phone frame detection, thereby improving the accuracy of the detection result, but also facilitate the taking and placing of the workpiece, thereby improving the detection efficiency.

[0087] Specifically, when the movable rod 420 moves downward, the clamping piece 422 moves downward with the movable rod 420, reducing the vertical distance between the clamping piece 422 and the workpiece, and at the same time, the clamping piece 422 rotates in a direction close to the bearing position, so that the clamping piece 422 can move to the bearing position to clamp the workpiece; when the movable rod 420 moves upward, the clamping piece 422 moves upward with the movable rod 420, increasing the vertical distance between the clamping piece 422 and the workpiece, and at the same time, the clamping piece 422 rotates in a direction away from the bearing position, so that the clamping piece 422 can release the workpiece and move out of the bearing position, avoiding the clamping piece 422 from blocking or interfering with the placement of the workpiece, making the placement of the workpiece more convenient.

[0088] refer to Figure 1 and Figure 2 There are multiple second positioning mechanisms 42, and each second positioning mechanism 42 is arranged around the bearing position at intervals to form a flat and stable pressing effect on the workpiece to prevent the workpiece from tilting or shaking.

[0089] Furthermore, a height pad 440 is provided on the bearing platform 44, and the height pad 440 is located on the side of the movable rod 420 close to the bearing position. When the movable rod 420 moves downward to the position of pressing the workpiece, the pressing member 422 faces the height pad 440, that is, the workpiece is clamped between the height pad 440 and the pressing member 422, and the height pad 440 supports the workpiece below to prevent the workpiece from collapsing or deforming downward, which affects the reliability of the workpiece pressing.

[0090] Furthermore, a coarse positioning block 442 may be provided on the support platform 44, and the coarse positioning block 442 surrounds the support position to define a placement area for the workpiece, ensuring that the workpiece is placed within the adjustment range of the first positioning mechanism 40, thereby enabling positioning of the workpiece in a horizontal plane.

[0091] Furthermore, the positioning device 4 further comprises a first driving member 5 and a second driving member 6, which provide power for the positioning device 4 to move, thereby realizing automatic adjustment of the positioning device 4. It is understandable that the power for the positioning device 4 to move can also be provided manually.

[0092] The first driving member 5 is disposed on one side of the first positioning mechanism 40, and is used to drive the first positioning mechanism 40 to move in the first direction and the second direction. For example, the first driving member 5 can be any mechanism capable of outputting a linear driving force, such as a cylinder, a gear rack mechanism, or a screw nut mechanism. The first driving member 5 can be fixedly connected to the bearing platform 44, so that the positioning device 4 forms a whole; the first driving member 5 can also be independently disposed from the bearing platform 44, so that the relative position of the first driving member 5 and the bearing platform 44 can be adjusted as needed.

[0093] The second driving member 6 is arranged at one side of the second positioning mechanism 42, and is used to drive the movable rod 420 to move along the bearing platform 44. For example, the second driving member 6 can be any mechanism capable of outputting a linear driving force, such as a cylinder, a gear rack mechanism, or a screw nut mechanism. The second driving member 6 can be fixedly connected to the bearing platform 44, so that the positioning device 4 forms a whole; the second driving member 6 can also be independently arranged from the bearing platform 44, so that the relative position of the second driving member 6 and the bearing platform 44 can be adjusted as needed.

[0094] refer to Figure 3-Figure 5 In this embodiment, the second positioning mechanism 42 further includes a mounting seat 426, the movable rod 420 is inserted into the mounting seat 426, and the guide pin 424 is detachably connected to the bearing platform 44 through the mounting seat 426, so that the second positioning mechanism 42 forms an integral body, which can not only improve the matching accuracy of the second positioning mechanism 42 itself, ensure the accuracy and reliability of the second positioning mechanism 42 action, but also facilitate the overall maintenance and replacement of the second positioning mechanism 42. Specifically, the mounting seat 426 is detachably connected to the bearing platform 44; the mounting seat 426 is provided with a mounting hole, and the movable rod 420 is inserted into the mounting hole; the guide pin 424 is fixedly connected to the mounting seat 426, and a part of the guide pin 424 extends into the mounting hole and slidably cooperates with the spiral groove 4200. In other embodiments, the guide pin 424 can be integrally formed on the bearing platform 44, and the guide pin 424 can also be detachably connected to the bearing platform 44 by fasteners such as screws, or connected to the bearing platform 44 by non-detachable methods such as welding.

[0095] It is understandable that in some embodiments, the spiral groove 4200 may be disposed on the side wall of the mounting seat 426 or the side wall of the support platform 44, and the guide pin 424 may be protruded on the side wall of the movable rod 420, as long as the movable rod 420 can be guided to rotate when the movable rod 420 passes through the support platform 44 up and down. The embodiments of the present application are described in detail by taking the spiral groove 4200 disposed on the side wall of the movable rod 420 and the guide pin 424 disposed on the mounting seat 426 as an example.

[0096] Continue to refer Figure 3-Figure 5 Furthermore, the angle of the spiral groove 4200 along the circumference of the movable rod 420 is not greater than 360°. For example, the angle of the spiral groove 4200 along the circumference of the movable rod 420 is 30°, 60°, 90°, 180° or 270°, etc. Preferably, the angle of the spiral groove 4200 along the circumference of the movable rod 420 is 90°, which can limit the rotation stroke of the movable rod 420, thereby limiting the rotation end point of the clamping member 422 and ensuring that the clamping member 422 can completely face the workpiece or avoid the workpiece, and can reduce the rotation resistance between the guide pin 424 and the spiral groove 4200, thereby making the rotation of the movable rod 420 more labor-saving and efficient.

[0097] Furthermore, an upper slide groove 4202 is provided on the side wall of the movable rod 420, and the upper slide groove 4202 extends upward in the vertical direction from the upper end of the spiral groove 4200. By setting the upper slide groove 4202, the clamping member 422 can be pressed or released along the vertical direction together with the movable rod 420, thereby avoiding accidents such as wear, scratches or displacement of the workpiece caused by the relative rotation of the clamping member 422 along the surface of the workpiece.

[0098] Specifically, when the movable rod 420 moves downward, the guide pin 424 first slides relatively along the spiral groove 4200, and at the same time, the clamping piece 422 rotates along with the movable rod 420 in the direction close to the bearing position; when the guide pin 424 is located at the upper end of the spiral groove 4200, the clamping piece 422 is located above the bearing position, and a gap is left between the clamping piece 422 and the workpiece; when the movable rod 420 moves further downward, the guide pin 424 slides into the upper slide groove 4202, at this time, the clamping piece 422 can only clamp the workpiece in the vertical direction, thereby avoiding the relative rotation of the clamping piece 422 along the surface of the workpiece. Similarly, when the movable rod 420 moves upward, the guide pin 424 first slides relatively along the upper slide groove 4202. At this time, the clamping piece 422 can only loosen the workpiece in the vertical direction; when the guide pin 424 slides into the upper end of the spiral groove 4200, the clamping piece 422 is located above the bearing position, and a gap is left between the clamping piece 422 and the workpiece. When the movable rod 420 moves further upward, the guide pin 424 slides relatively along the spiral groove 4200, thereby causing the clamping piece 422 to rotate along with the movable rod 420 in a direction away from the bearing position.

[0099] Furthermore, a downward sliding groove 4204 is provided on the side wall of the movable rod 420, and the downward sliding groove 4204 extends downward in a vertical direction from the lower end of the spiral groove 4200. By providing the downward sliding groove 4204, the resistance to the downward movement of the movable rod 420 can be reduced, thereby forming a larger initial acceleration when the movable rod 420 moves downward, thereby avoiding accidents such as the movable rod 420 getting stuck and having difficulty in clamping the workpiece.

[0100] Specifically, when the movable rod 420 moves downward, the guide pin 424 first slides relatively along the lower sliding groove 4204, that is, the movable rod 420 has almost no movement resistance in the vertical direction, so that the movable rod 420 can move downward with a large initial acceleration; as the movable rod 420 moves downward, the guide pin 424 slides into the spiral groove 4200, and under the inertia of the movable rod 420, the guide pin 424 can slide relatively along the spiral groove 4200 at a relatively high speed, thereby reducing the possibility of accidents such as jamming of the guide pin 424 and the spiral groove 4200.

[0101] Furthermore, the second positioning mechanism 42 further includes a clamping elastic member 428 (e.g., a spring, a spring sheet, or a rubber member, etc.). The two ends of the clamping elastic member 428 are respectively connected (including direct connection and indirect connection) to the movable rod 420 and the bearing platform 44, so as to force the movable rod 420 to drive the clamping member 422 to move in the direction of clamping the workpiece, that is, under the action of the clamping elastic member 428, the clamping member 422 has a tendency to move in the direction of clamping the workpiece, so that the clamping member 422 can automatically clamp the workpiece and stably maintain the state of clamping the workpiece, ensuring that the position of the workpiece does not change.

[0102] Specifically, the compression elastic member 428 can at least provide a downward driving force to the movable rod 420. The compression elastic member 428 can be a pre-tensioned member disposed above the bearing platform 44, so that the compression elastic member 428 can apply a downward pulling force to the movable rod 420; the compression elastic member 428 can be a pre-compression member disposed below the bearing platform 44, so that the compression elastic member 428 can apply a downward thrust to the movable rod 420.

[0103] In this embodiment, the clamping elastic member 428 is sleeved on the movable rod 420. One end of the clamping elastic member 428 elastically presses against the stop step provided on the movable rod 420. For example, the movable rod 420 can be provided as an integrally formed stepped shaft, or a detachable connecting sleeve 429 or a gasket is provided on the outer side of the movable rod 420 to form a step; the other end of the clamping elastic member 428 elastically presses against the mounting seat 426 fixed on the bearing platform 44. In other words, the clamping elastic member 428 is indirectly connected to the bearing platform 44 through the mounting seat 426, so that the clamping elastic member 428, the movable rod 420, the guide pin 424 and the mounting seat 426 form a whole, further improving the integrity of the second positioning mechanism 42.

[0104] refer to Figure 6-Figure 8 The first positioning mechanism 40 includes a first movable member 400 and a second movable member 402. The first movable member 400 is slidably connected to the carrier 44 and can reciprocate along the first direction. The first movable member 400 is provided with a first positioning portion 4000 for pushing the workpiece along the first direction; the second movable member 402 is slidably connected to the carrier 44 and can reciprocate along the second direction. The second movable member 402 is provided with a second positioning portion 4020 for pushing the workpiece along the second direction; the second movable member 402 and the second movable member 402 are mutually pressed through the wedge-shaped mating surface 400a, and the movement in the first direction is converted into the movement in the second direction through the wedge-shaped surface, or the movement in the second direction is converted into the movement in the first direction, so that the second movable member 402 and the first movable member 400 are linked, and can push the workpiece in the first direction and the second direction at the same time.

[0105] Furthermore, the first positioning mechanism 40 also includes a positioning elastic member 404 (for example, a spring, a spring sheet or a rubber member, etc.). The positioning elastic member 404 can be arranged between the first movable member 400 and the bearing platform 44 to force the first movable member 400 to drive the first positioning portion 4000 to move in the direction of pushing the workpiece, that is, under the action of the positioning elastic member 404, the first positioning portion 4000 has a tendency to move in the direction of pushing the workpiece, so that the first positioning portion 4000 can automatically push the workpiece and stably maintain the state of pushing the workpiece, thereby ensuring the positioning accuracy of the workpiece along the first direction. Similarly, the positioning elastic member 404 can also be arranged between the second movable member 402 and the bearing platform 44 to force the second movable member 402 to drive the second positioning portion 4020 to move in the direction of pushing the workpiece.

[0106] Furthermore, the second positioning portion 4020 includes a main body portion 4020a and at least two abutting portions 4020b. The main body portion 4020a is disposed at one side of the bearing position and extends along the first direction; the abutting portion 4020b is disposed at one side of the main body portion 4020a facing the bearing position and is used to push the workpiece for positioning; the abutting portions 4020b are arranged at intervals along the first direction, thereby forming a plurality of positioning points distributed at intervals, thereby improving positioning accuracy.

[0107] Furthermore, the abutment portion 4020b can be extended and retracted along the second direction. For example, the abutment portion 4020b is made of elastic material, or an elastic retractable member is provided between the abutment portion 4020b and the main body portion 4020a. This can not only adjust the relative position of the first positioning portion 4000 and the second positioning portion 4020 to avoid over-positioning or under-positioning of the workpiece, but also play a role in buffering and shock absorption to reduce scratches on the surface of the workpiece.

[0108] like Figure 9-11 As shown, the embodiment of the present application further provides a detection device, which includes a frame 2, a workbench 3, at least one positioning device 4 provided in the embodiment of the present application, and at least one detection device 7. The frame 2 is provided with at least one detection position 22, and the workbench 3 is rotatably connected to the frame 2; the positioning device 4 is connected to the workbench 3, and is used to place the workpiece, and to position and press the workpiece; the detection device 7 is set at the detection position 22, and the detection device 7 is connected to the frame 2. When the workpiece rotates to the detection position 22 together with the positioning device 4, the detection device 7 detects the workpiece, thereby realizing the automatic detection of the workpiece and improving the detection efficiency.

[0109] A shell 1 may be disposed outside the frame 2, and the workbench 3, the positioning device 4 and the detection device 7 are all accommodated in the shell 1. The shell 1 provides protection to prevent personnel from entering the dangerous area and being injured.

[0110] Furthermore, the frame 2 is also provided with at least one clamping position 20. When the positioning device 4 rotates to the clamping position 20 along with the workbench 3, the workpiece is placed on the positioning device 4 manually or by a robot, and the workpiece is positioned and clamped, which further improves the convenience of operation.

[0111] Furthermore, the frame 2 is also provided with at least one offline position 24, and the assembly line 8 can be set at the offline position 24. When the positioning device 4 rotates to the offline position 24 along with the workbench 3, the workpiece is removed manually or by a robot and placed on the assembly line 8 to enter the next production process.

[0112] In one embodiment, the first driving member 5 and the second driving member 6 are independent of the carrier 44, and the first driving member 5 and the second driving member 6 are arranged at the clamping position 20, that is, the driving member is only arranged at the clamping position 20, and there is no need to arrange a separate driving member for each positioning device 4, thereby reducing the number of driving members, thereby simplifying the overall structure, reducing power consumption, and reducing production costs. The first driving member 5 is located on one side of the workbench 3, and the first driving member 5 telescopically moves in the horizontal direction, and is used to push the first positioning mechanism 40 to move away from the workpiece; the second driving member 6 is located below the workbench 3, and the second driving member 6 telescopically moves in the vertical direction, and is used to drive the movable rod 420 to drive the clamping member 422 to move away from the workpiece. When the positioning device 4 rotates to the clamping position 20 along with the workbench 3, the first driving member 5 pushes the first positioning mechanism 40 to move, and the second driving member 6 pushes the second positioning mechanism 42 to move, thereby forming a larger operating space at the load-bearing position to facilitate the placement of the workpiece; when the first driving mechanism releases the first positioning mechanism 40, the positioning of the workpiece in the horizontal plane is completed; when the second driving mechanism releases the second positioning mechanism 42, the clamping of the workpiece is completed.
