TECHNICAL FIELD
[0001] The present application belongs to the field of watch production, and particularly relates to a testing device and a watch production line. BACKGROUND
[0002] In the field of watch manufacturing and quality detection, the assembly quality of the lugs is one of the key factors affecting the safety of watch wearing and user experience. The lug is a protruding part on both sides of the watch case for connecting the watch band or watch chain, and a hole or groove is usually designed inside the lug. The spring rod serves as a connecting block, and both ends are provided with a compression spring, which needs to be precisely clamped into the lug hole to fix the watch band or watch chain. The reliability of the connection directly determines whether the watch will accidentally fall off, and the damping force of the lug is the core index for evaluating this quality. Therefore, the torque of the lug relative to the watch case needs to be tested to obtain the damping force data of the lug.
[0003] However, in the current lug torque detection process, when multiple watches need to be detected or the same watch needs to be detected multiple times, the initial angle between the lug and the watch case before testing fluctuates randomly, resulting in differences in the angle between the lug and the watch case. This difference causes significant fluctuations in the test results of the lug torque, and the consistency of the torque test is poor. SUMMARY

[0034] Please refer to Figures 1 to 10 The embodiment of the present application provides a test device for detecting a target workpiece 200, the target workpiece 200 comprising a first component 210 and a second component 220 rotationally connected with the first component 210, the test device comprising a fixing structure 40 for fixing the first component 210, a moving structure 10 for driving the fixing structure 40 to move, and a shaping device 20 and a test device 30 arranged in sequence along the moving path of the fixing structure 40, the moving structure 10 drives the fixing structure 40 to move to the shaping device 20, the shaping device 20 is used for angle adjustment of the first component 210 and the second component 220, so that a preset angle is formed between the second component 220 and the first component 210, and the moving structure 10 is further used for driving the fixing structure 40 to move to the test device 30 after the angle adjustment, the test device 30 is used for driving the second component 220 to rotate relative to the first component 210, and detecting the torque of the second component 220 when the second component 220 rotates.
[0035] It should be noted that the target workpiece 200 in the embodiments of the present application is a watch, the first component 210 and the second component 220 are respectively a watch case and a watch ear of the watch, the watch ear is a protruding part on both sides of the watch case for connecting a watchband or a watch chain, a hole or a groove is usually designed inside the watch ear, the spring rod serves as a connecting block 331, both ends of the spring rod are provided with compression springs, and the spring rod needs to be accurately clamped into the hole of the watch ear to fix the watchband or the watch chain, therefore, the test equipment in the embodiments of the present application can detect the torque of the rotation of the watch ear relative to the watch case, and then obtain the damping force of the watch ear, and the damping force is a core index for evaluating the assembly quality of the watch. Of course, in other possible embodiments, the target workpiece 200 can also be other structures, and the embodiments of the present application do not make a unique limitation to the specific structure of the target workpiece 200.
[0036] In the embodiments of the present application, the first component 210 and the second component 220 after testing can be continuously conveyed by the moving structure 10 and the fixed structure 40 to the next station, such as the next test station, or taken away by a downstream device of the moving structure 10, such as a mechanical hand.
[0037] When the test equipment of the present application is used, the moving structure 10 drives the fixed structure 40 to move to the shaping device 20, the shaping device 20 adjusts the angle between the first component 210 and the second component 220, so that the second component 220 forms a preset angle with the first component 210, then the moving structure 10 drives the fixed structure 40 to move to the test device 30, and the test device 30 drives the second component 220 to rotate relative to the first component 210 and detects the torque of the second component 220. Therefore, by adjusting the angle before testing through the setting of the shaping device 20, the initial angle of the first component 210 and the second component 220 is uniformly calibrated to the same reference value, which ensures that the second component 220 is at the same reference angle position relative to the first component 210 before each test, thereby eliminating the error caused by different testing references and improving the consistency of testing; and the fixed structure 40 fixes the first component 210 during the detection process, which ensures that the first component 210 does not shake or displace during the detection process, thereby effectively reducing the measurement deviation caused by the unstable position of the first component 210 and further improving the accuracy of detection.
[0038] Optionally, the range of the preset angle is 90°-180°, and the preset angle can be flexibly set according to different testing requirements. Specifically, the preset angle in the embodiments of the present application is 180°, that is, the first component 210 and the second component 220 are located on the same horizontal plane.
[0039] It can be understood that the embodiment of the present application also includes a control system (not shown in the figure), the mobile structure 10, the fixed structure 40, the shaping device 20 and the testing device 30 are all connected with the control system, and the control system can control the mobile structure 10, the fixed structure 40, the shaping device 20 and the testing device 30 to cooperate and operate automatically. The whole process is realized through the automatic cooperation and operation of the mobile structure 10, the fixed structure 40, the shaping device 20 and the testing device 30, so that the automation degree is greatly improved, the manual operation is reduced, and the shaping efficiency is greatly improved.
[0040] In some embodiments, as shown in Figure 2 and Figure 3 The testing device 30 includes a base 310, a connecting shaft assembly 320 rotatably connected with the base 310, a clamping structure 330 connected with the connecting shaft assembly 320 and used for clamping the second member 220, and a torque sensor 340 connected with the connecting shaft assembly 320. The connecting shaft assembly 320 is used for rotating around a preset axis under the driving of an external force, so that the clamping structure 330 drives the second member 220 to rotate relative to the first member 210. The torque sensor 340 is used for detecting the torque of the second member 220 when the connecting shaft assembly 320 drives the clamping structure 330 to rotate. The connecting shaft assembly 320 rotates around the preset axis under the driving of the external force, the clamping structure 330 rotates with the connecting shaft assembly 320, and the clamping structure 330 also rotates around the preset axis, so that the clamping structure 330 can drive the second member 220 to rotate relative to the first member 210. At this time, the torque sensor 340 detects the torque of the connecting shaft assembly 320, thereby indirectly obtaining the torque data of the second member 220, and the measurement of the torque is accurate.
[0041] The torque value of the second member 220 in the rotating process is measured by the torque sensor 340, and a digital signal or a quantitative reading is output, which replaces the fuzzy evaluation depending on the manual feeling, can improve the accuracy of detection, and the first member 210 is fixed by the fixed structure 40 during the detection process, so as to ensure that the first member 210 does not shake or displace during the detection process, thereby effectively reducing the measurement deviation caused by the unstable position of the first member 210, and further improving the stability and accuracy of the detection.
[0042] It can be understood that the contact surface between the clamping structure 330 and the second member 220 can be a soft contact surface, so that the clamping structure 330 can reliably, non-destructively and consistently clamp the second member 220, and the measurement deviation and the risk of component damage caused by unstable clamping can also be eliminated. In addition, the same first member 210 and second member 220 can be tested multiple times under the same conditions, so that the repeatability error of the torque measurement result is much better than the fluctuation range of the manual evaluation.
[0043] In some embodiments, as shown inFigure 3 As shown, the test device 30 further comprises a first driving structure 350 connected to the base 310, and the connecting shaft assembly 320 is connected to the rotating output end of the first driving structure 350, and the first driving structure 350 is used to drive the connecting shaft assembly 320 to rotate around the preset axis. By driving the connecting shaft assembly 320 to rotate through the first driving structure 350, the clamping structure 330 and the second member 220 are driven to rotate, the rotation mode of the second member 220 can be accurately simulated, the torque required for the rotation action can be directly measured, the error introduced by the indirect measurement mode such as axial tension is excluded, and it is ensured that the measurement result truly reflects the damping force data of the second member 220.
[0044] In addition, by setting the first driving structure 350 to drive, the test efficiency can be improved, the consistency of the test is ensured, and the operator only needs to place the first member 210 and start the button, and the device automatically completes the fixing, clamping, rotation, measurement and result determination, greatly reduces the operation complexity and the requirement for personnel skills, and the test device 30 of the embodiment of the application is easy to integrate into an automatic production line or an online detection station, and meets the efficient production rhythm. Alternatively, the first driving structure 350 can be a rotary motor, a rotary cylinder or a precision rotary table.
[0045] In some embodiments, the connecting shaft assembly 320 and the first driving structure 350 can also be connected to an electromagnetic clutch. When the electromagnetic clutch is in a closed state, the first driving structure 350 is started, and the electromagnetic clutch transmits the power of the first driving structure 350 to the connecting shaft assembly 320, and when the clamping structure 330 or the connecting shaft assembly 320 rotates under the action of an external force, the electromagnetic clutch can be switched to an open state, and then the connecting shaft assembly 320 is driven to idle, so that the power on the connecting shaft assembly 320 is prevented from being reversely transmitted to the first driving structure 350, thereby realizing the one-way output of the power of the first driving structure 350 and improving the safety of the test device 30.
[0046] In some embodiments, as shown in Figs. 1 and 2, Figure 2 and Figure 3 As shown, the connecting shaft assembly 320 comprises a plurality of connecting pieces 321 connected in sequence, the torque sensor 340 is arranged between two adjacent connecting pieces 321, and the connecting piece 321 at the end of the connecting shaft assembly 320 away from the clamping structure 330 is connected to the rotating output end of the first driving structure 350. By setting the connecting piece 321, when the first driving structure 350 is started, the connecting piece 321 can rotate, so as to realize the rotation of the clamping structure 330 to realize the rotation operation of the second member 220, and at this time the connecting piece 321 can realize the overload protection of the torque sensor 340, and improve the protection of the whole test device 30.
[0047] The torque sensor 340 has a very high sampling frequency and fast response capability, which can capture the slight changes of torque in a short time, thereby realizing real-time monitoring of the device. At the same time, the sensor also has the stability of quality, which can maintain stable performance even in harsh working environment, ensuring the reliability of the measurement data. The torque sensor 340 also has strong anti-interference ability and anti-overload ability, which can effectively resist the influence of external interference signals, and can maintain normal work even when subjected to overload torque, greatly improving the safety and reliability of the device, and ensuring the accuracy of the measurement data.
[0048] In some embodiments, the clamping structure 330 includes a connecting block 331 connected to the connecting shaft assembly 320 towards one end of the fixed structure 40, and two clamping arms 332 connected to the connecting block 331 away from the connecting shaft assembly 320, the two clamping arms 332 are spaced apart, and a clamping space for clamping the second member 220 is formed between the two clamping arms 332. It can be understood that the rotating power of the connecting shaft assembly 320 is first transmitted to the connecting block 331, and then transmitted to the two clamping arms 332 through the connecting block 331, and the second member 220 is clamped between the two clamping arms 332. The clamping structure 330 is simple, which can improve the clamping efficiency.
[0049] In some embodiments, the base 310 includes a base 311 and a sliding seat 312 slidingly connected to the base 311, and the connecting shaft assembly 320 is rotationally connected to the sliding seat 312. The sliding direction of the sliding seat 312 is parallel to the direction of the preset axis. Since the sliding seat 312 is slidingly connected to the base 311, it can drive the connecting shaft assembly 320 and the clamping structure 330 to move towards the fixed structure 40, so that the clamping structure 330 can clamp the second member 220, and the clamping structure 330 can be retracted when the first member 210 is removed or placed, avoiding interference.
[0050] In some embodiments, the clamping arm 332 is detachably connected to the connecting block 331. Since the clamping arm 332 is detachably connected to the connecting block 331, the clamping arm 332 can be easily detached, thereby improving the convenience of maintenance, and different sizes and shapes of clamping arms 332 can be selected according to different sizes and shapes of the first member 210 and the second member 220, thereby improving the adaptability and flexibility of the testing device 30. A plurality of clamping structures 330 are not required, and only the clamping arm 332 needs to be replaced, thereby saving costs. Specifically, connecting holes can be provided on the clamping arm 332 and the connecting block 331, and fasteners can pass through the connecting holes on the clamping arm 332 and the connecting holes on the connecting block 331 respectively, thereby achieving detachable connection of the clamping arm 332 and the connecting block 331.
[0051] Optionally, the clamping arm 332 is made of aluminum alloy. In addition, the contact surface of the clamping arm 332 and the second member 220 can be provided with a buffer layer made of soft or flexible material, such as Teflon, engineering plastic or soft alloy, to avoid hard contact between the clamping arm 332 and the second member 220, thereby avoiding damage to the second member 220.
[0052] In some embodiments, as shown in Figure 4 The shaping device 20 includes a pressing structure and a second driving structure 230 for driving the pressing structure to move up and down along the first direction a. The moving structure 10 drives the fixed structure 40 to move below the pressing structure, and the second driving structure 230 is used to drive the pressing structure to move a preset distance towards the second member 220, so that the pressing structure pushes the second member 220 and drives the second member 220 to rotate to form a preset angle with the first member 210.
[0053] It should be noted that the second driving structure 230 drives the pressing structure to move a preset distance towards the fixed structure 40, and the second member 220 is pushed to rotate to form a preset angle with the first member 210. The preset angle is related to the preset distance.
[0054] Optionally, the second driving structure 230 is a lifting cylinder or a lifting motor, and the pressing structure is connected with the output end of the second driving structure 230. By driving the pressing structure to move through the second driving structure 230, the movement stroke of the pressing structure is accurately controllable, avoiding insufficient or excessive pushing distance, improving the reliability of the shaping, and the pushing force of the pressing structure is directly applied to the second member 220, the direction is clear, avoiding misoperation or force dispersion. And by setting the second driving structure 230, each shaping is executed by the mechanical structure according to the preset program, the pushing distance, speed and force are highly consistent, completely eliminating the uncertainty of manual operation, ensuring the stability of product quality.
[0055] In some embodiments, as shown in Figure 4 and Figure 5As shown, the fixing structure 40 has a limiting surface 600 facing the pressing structure, when the fixing structure 40 moves to below the pressing structure, the second member 220 is located between the limiting surface 600 and the pressing structure, the limiting surface 600 is used to resist the second member 220 during the rotation of the second member 220, so as to limit the rotation angle of the second member 220. When the second driving structure 230 drives the pressing structure to push the second member 220, the second member 220 is pressed to rotate, and the limiting surface 600 is located on the rotation path of the second member 220, so that the limiting surface 600 can resist the second member 220 during the rotation of the second member 220, and by setting the height of the limiting surface 600, the second member 220 can be resisted after rotating a preset angle, so as to limit the rotation angle of the second member 220, and ensure that the second member 220 will not rotate excessively, thereby improving the accuracy of the shaping action.
[0056] In some embodiments, the fixing structure 40 has a bearing surface 700 for bearing the first member 210, and the bearing surface 700 is parallel to the limiting surface 600. It can be understood that if the initial angle formed between the first member 210 and the second member 220 is 20°, the second member 220 is rotated under the pushing force, and when the limiting surface 600 resists the second member 220, the second member 220 abuts against the limiting surface 600 at this time, and the bearing surface 700 is parallel to the limiting surface 600, so that the plane where the second member 220 is located is parallel to the plane where the first member 210 is located at this time, that is, the angle between the first member 210 and the second member 220 at this time is 180°. It can be understood that when it is required to adjust the angle between the first member 210 and the second member 220 to other angles, the inclination angle of the limiting surface 600 relative to the bearing surface 700 can be changed.
[0057] In some embodiments, as shown in Figure 6 and Figure 7 As shown, the fixing structure 40 includes a placing seat 43 for bearing the first member 210, a first clamping member 41 arranged on the placing seat 43, and a second clamping member 42 arranged in the second direction b and spaced apart from the first clamping member 41, and the second clamping member 42 is used to move towards the first clamping member 41 to clamp the first member 210 together with the first clamping member 41. The second clamping member 42 moves towards the first clamping member 41 to clamp the first member 210 together with the first clamping member 41, so as to realize the positioning of the first member 210, and the positioning mode is simple, which ensures that the first member 210 will not shake or displace during detection and shaping, thereby improving the reliability of shaping and testing.
[0058] In addition, by arranging the first clamping member 41 and the second clamping member 42, the distance between the first clamping member 41 and the second clamping member 42 is adjustable, so that after the first component 210 is placed on the placement seat 43, the second clamping member 42 slides towards the first clamping member 41 to clamp the first component 210, and when the first component 210 needs to be removed, the second clamping member 42 slides away from the first clamping member 41 to release the first component 210.
[0059] In some embodiments, the fixing structure 40 further comprises a power member 44 arranged at a distance from the placement seat 43, the second clamping member 42 is connected to the output end of the power member 44, and the power member 44 is used to drive the second clamping member 42 to move so as to move the second clamping member 42 towards or away from the first clamping member 41. By arranging the power member 44, the manual intervention can be reduced, the clamping efficiency can be improved, and the consistency of clamping can be ensured.
[0060] In some embodiments, the fixing structure 40 further comprises a limiting block 45 connected to the edge of the placement seat 43, and a plurality of limiting blocks 45 are arranged at a distance along the circumference of the placement seat 43.

[0061] In some embodiments, the shape of the limiting space is adapted to the outer contour of the first component 210, that is, the plurality of limiting blocks 45 surround to form a contoured cavity for accommodating the first component 210. Since the contoured cavity highly matches the outer contour of the first component 210, a maximum contact area is provided, and the possible slight shaking or rotational freedom of the first component 210 during positioning is eliminated. The plurality of complex curved surfaces simultaneously contact and constrain, so that the first component 210 can be accurately and uniquely fixed at the expected position and direction. Specifically, the first component 210 is a circular ring structure, and the plurality of limiting blocks 45 form a circular ring array along the center of the first component 210.
[0062] In some embodiments, the limiting block 45 has an abutting surface 451 abutting the first component 210, and the abutting surface 451 is adapted to the shape of the outer surface of the first component 210.

[0063] In addition, the contact surface of the second clamping member 42 and the first member 210 is provided with a buffer 46, which is made of flexible material and is used to buffer the vibration caused by the contact between the second clamping member 42 and the first member 210. The material of the buffer 46 can be Teflon, engineering plastic or soft alloy, etc. to avoid the hard contact between the second clamping member 42 and the first member 210, thereby avoiding the damage to the first member 210.
[0064] In some embodiments, as shown in Figure 4 The pressing structure includes a mounting base 221 connected to the output end of the driving structure, a pressing head 222 located below the mounting base 221 and used to contact the second member 220, and a buffer structure 223 provided between the mounting base 221 and the pressing head 222 and used to buffer the vibration of the pressing head 222 caused by the contact between the second member 220 and the pressing head 222. When the second member 220 and the pressing head 222 contact, the buffer structure 223 can buffer the vibration of the pressing head 222 caused by the contact between the second member 220 and the pressing head 222, so as to avoid the rigid contact between the second member 220 and the pressing head 222, thereby preventing the damage to the second member 220 and the pressing head 222.
[0065] In some embodiments, the buffer structure 223 includes a connecting rod 2231 extending along the first direction a and an elastic member 2232 sleeved on the connecting rod 2231, one end of the connecting rod 2231 is connected to the pressing head 222, the other end of the connecting rod 2231 away from the pressing head 222 is movably provided in the mounting base 221, and the two ends of the elastic member 2232 along the first direction a are respectively elastically abutted against the pressing head 222 and the mounting base 221. By providing the elastic member 2232, the appropriate pressure can be ensured, and in addition, the damage to the pressing head 222 caused by the excessive impact force when the second member 220 and the pressing head 222 contact can be effectively prevented, and the second member 220 of different sizes can be adapted to ensure sufficient buffering amount. Optionally, the elastic member 2232 of the embodiment of the present application is a spring.
[0066] In addition, since the second member 220 can be provided in plurality, for example, when the first member 210 and the second member 220 are respectively a watch case and a watch ear of a watch, the watch ear is provided with two and is respectively located at the opposite sides of the watch case, at this time, the pressing structure includes two pressing heads 222, the two pressing heads 222 are provided in interval and are respectively used to push the two second members 220 connected to the same first member 210. Correspondingly, the buffer structure 223 is correspondingly provided in two, and each buffer structure 223 corresponds to each pressing head 222 one by one.
[0067] In some embodiments, the shaping device 20 further comprises a guide structure 240 connected between the mounting seat 221 and the outer wall of the driving structure, the guide structure 240 being used to guide the movement of the mounting seat 221 along the first direction a. By providing the guide structure 240, the movement of the mounting seat 221 and the pressing head 222 is more stable and reliable, and the movement of the pressing head 222 can be effectively prevented from deviating. Optionally, the guide structure 240 comprises a guide rail 241 connected to the outer wall of the driving structure and extending along the first direction a, and a sliding plate 242 slidingly connected to the guide rail 241, the mounting seat 221 being connected to the sliding plate 242, so as to achieve the sliding connection between the mounting seat 221 and the guide rail 241.
[0068] In some embodiments, as shown in Figure 1 The moving structure 10 comprises a rack 11, a rotating disc 12 rotatably connected to the rack 11, and a rotating driver 13 provided on the rack 11 and connected to the rotating disc 12. The fixed structure 40 is provided at the edge of the rotating disc 12, and the shaping device 20 and the testing device 30 are arranged at intervals along the circumference of the rotating disc 12. The rotating axis of the rotating disc 12 is parallel to the first direction a, and the rotating driver 13 is used to drive the rotating disc 12 to rotate so that the fixed structure 40 is sequentially docked with the shaping device 20 and the testing device 30. By driving the fixed structure 40 to rotate through the rotating disc 12, compared with the linear layout in which the fixed structure 40 is transmitted along a straight line, the occupying area is smaller and the structure is more compact, which is beneficial to reducing the occupying space of the shaping device 20.
[0069] Optionally, a plurality of fixed structures 40 can be provided on the rotating disc 12, and the rotating disc 12 drives each fixed structure 40 to be sequentially docked with the shaping device 20 and the testing device 30. The movement of the entire system only needs one rotating driver 13 to drive the conveying of all the fixed structures 40, which greatly simplifies the driving and control system, and does not need a complex linear conveying belt system, a multi-axis mechanical arm, or a large number of independent push cylinders to realize the transfer of the fixed structure 40 between the shaping device 20 and the testing device 30.
[0070] Optionally, the rotating driver 13 can comprise a stepping motor, a speed reducer, and an indexing structure. The stepping motor provides precise angle control, and the rotation angle and speed are controlled by receiving pulse signals. The speed reducer is usually a planetary reducer or a worm and gear reducer, which is used to reduce the output speed of the motor while greatly increasing the output torque, so as to meet the requirements of driving the rotating disc 12 with large inertia, improve the rigidity of the system, and reduce vibration. The indexing mechanism is the key to realize precise indexing positioning. The indexing mechanism can specifically adopt a cam divider. The cam divider internally adopts a conjugate cam structure to convert the continuous rotation of the motor into the intermittent and precise indexing movement of the rotating disc 12, which has high positioning accuracy and repeat positioning accuracy, strong carrying capacity, good rigidity, stable operation, and long service life. It is suitable for high-speed, high-precision, and heavy-load occasions.
[0071] In addition, since the second member 220 can be provided in plurality, such as when the first member 210 and the second member 220 are a watch case and a watch ear respectively, the watch ear is provided in two, and is located at opposite sides of the watch case respectively, at this time, the test device 30 can be provided in two at intervals, and the two test devices 30 are arranged along the circumference of the turntable 12, and are respectively used for detecting the two second members 220 connected to the same first member 210.

It can be understood that the target workpiece 200 can have a one-dimensional code, a bar code, a serial number and the like identification code, which is used to reflect the relevant information of the target workpiece 200, and the identification structure 50 is used for scanning code recognition of the identification code to obtain the information of the target workpiece 200, so as to facilitate subsequent detection of the target workpiece 200.

[0074] When the fixing structure 40 receives the target workpiece 200 at the flow transfer device, at this time, the pressing structure of the shaping device 20 and its working area and the feeding area of the target workpiece 200 are separated from each other in spatial layout, and the feeding work of the target workpiece 200 completely avoids the spatial limitation of the shaping area, which is beneficial to improve the convenience of feeding of the shaping device 20.
[0075] In some embodiments, the flow transfer device comprises a support frame 640 arranged in parallel with the moving structure 10, a first conveying line 610 arranged on the support frame 640, a second conveying line 620 arranged in parallel with the first conveying line 610, a third conveying line 630 arranged in parallel with the second conveying line 620, and a material moving structure 650 arranged on the support frame 640, one side of the support frame 640 is provided with a loading station 300 and a first unloading station 400 arranged in parallel, the first conveying line 610 receives the target workpiece 200 at the loading station 300, the material moving structure 650 is used to pick up the target workpiece 200 from the first conveying line 610 and move the target workpiece 200 to the fixing structure 40, the material moving structure 650 is also used to transfer the target workpiece 200 that passes the test from the fixing structure 40 to the second conveying line 620, and transfer the target workpiece 200 that fails the test from the fixing structure 40 to the third conveying line 630, and the third conveying line 630 unloads the target workpiece 200 at the first unloading station 400.
[0076] The material moving structure 650 can transfer the target workpiece 200 loaded from the loading station 300 to the first conveying line 610 to the fixing structure 40 on the moving structure 10, the moving structure 10 drives the fixing structure 40 to move to the test device 30 for testing, after the test is completed, the moving structure 10 drives the fixing structure 40 to move to the flow transfer device, the material moving structure 650 transfers the target workpiece 200 that passes the test from the fixing structure 40 to the second conveying line 620, and transfers the target workpiece 200 that fails the test from the fixing structure 40 to the third conveying line 630, thereby the flow transfer device of the present application can automatically transfer the target workpiece 200 that passes the test and the target workpiece 200 that fails the test to different positions, so as to facilitate subsequent processing of the target workpiece 200, and facilitate improvement of production efficiency; and the loading station 300 and the first unloading station 400 are arranged on the same side of the support frame 640, which facilitates the operator to simultaneously check the loading condition of the target workpiece 200 to be tested on the first conveying line 610 and the unloading condition of the target workpiece 200 that fails the test on the third conveying line 630, so that it is not necessary to arrange operators at both the loading station 300 and the first unloading station 400, thereby reducing labor cost.

By arranging the second unloading station 500 on the other side of the support frame 640 away from the first unloading station 400, the other side of the support frame 640 away from the first unloading station 400 can be connected to the equipment of the next process, and after the second conveying line 620 receives the target workpiece 200 that passes the test, the target workpiece 200 that passes the test can be continuously conveyed forward, thereby improving the flow transfer efficiency of the target workpiece 200.
[0078] In some embodiments, a plurality of first conveying lines 610 are arranged at intervals, and the plurality of first conveying lines 610 are all independent of each other and can convey the target workpiece 200. Specifically, when there are many target workpieces 200 to be tested, the flow transfer device of the present application can be arranged in multiple, and one of the first conveying lines 610 of the previous flow transfer device is not picked up by the material transfer structure 650, so that the target workpiece 200 of the first conveying line 610 continues to be conveyed forward to the next flow transfer device, thereby realizing simultaneous feeding and testing of multiple flow transfer devices, thereby greatly improving the production efficiency and avoiding production intermittence. Specifically, two first conveying lines 610 are arranged at intervals in the present application, and the two first conveying lines 610 are arranged between the second conveying line 620 and the third conveying line 630.
[0079] In some embodiments, the material transfer structure 650 includes a linear motion structure 651 and a picking mechanism 652 slidingly arranged on the linear motion structure 651, the linear motion structure 651 is adjacent to the moving structure 10, the linear motion structure 651 is used to drive the picking mechanism 652 to move in a three-dimensional space, and the picking mechanism 652 is used to pick up the target workpiece 200. By driving the picking mechanism 652 to move through the linear motion structure 651, the displacement accuracy of the picking mechanism 652 can be improved, so that the picking mechanism 652 can accurately move to a preset position.

By adsorbing the target workpiece 200 through the suction cup 6522, and then driving the two clamping blocks 6523 to move towards each other and clamping the target workpiece 200 adsorbed on the suction cup 6522 through the driving element, the stability of picking the target workpiece 200 can be improved, and the target workpiece 200 can be prevented from falling during movement.
[0082] The application further provides a watch production line, which comprises a testing device, and the specific structure of the testing device is referred to the above-mentioned embodiments. Since the watch production line adopts all the technical solutions of the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

Moreover, the first member 210 is fixed by the fixed structure 40 during the detection process, which ensures that the first member 210 does not shake or displace during the detection process, thereby effectively reducing the measurement deviation caused by the unstable position of the first member 210 and further improving the accuracy of the detection.
