[0023] 2.1. In the embodiment of the present application, the clamping device implements the two key actions of clamping (clamping or releasing) and power-on in two steps. On the one hand, when clamping the material, there is no need to consider the power-on action, which can improve the efficiency of loading.

The optical fiber module can be coiled and will not shake during the test, which will not affect the test results. An outer chamfer is set on the outer side wall of the test chamber to facilitate clamping the pump source module. A heat dissipation structure is set in the pump source module to achieve heat dissipation of the pump source module, which can reduce unnecessary damage to the pump element module during the test.
[0029] 4.

The temperature monitoring module can be set above the cover plate of the pump unit, or other positions that are prone to temperature changes. The temperature monitoring module is used to monitor the temperature change at the connection between the pump source module and the optical fiber module, and transmit the temperature change value to the control device. The control device can implement emergency stop control according to the temperature change.
[0031] 6. The embodiment of the present application also includes an automated loading device. On the one hand, the loading device is arranged below the rotating device and does not affect the rotation of the rotating device carrying the clamping body between different workstations. On the other hand, the device to be tested can be loaded when it runs to the motion cutoff part in the transmission of the loading crawler, and the loading process can be seamlessly connected.
[0032] 7. The embodiment of the present application also includes an automated unloading device. The unloading device includes a supporting member and an unloading track. The supporting member can be raised and lowered and rotated, which is convenient for unloading operations, and does not affect the rotation device driving the clamping device to rotate to the loading position, thereby improving the operating efficiency of the system. The unloading track may include two tracks arranged at intervals, which is convenient for the supporting member to place the tested device that has completed the test, and at the same time can ensure that during the unloading process, the tested device that has completed the test will not encounter any accidents (such as bumps or overturning).

[0042] See also Figure 1 , Figure 2 , Figure 3 and Fig.11 The present application provides an automated testing system 100, including: a fixing device 10, a rotating device 20, a clamping device 30, a device to be tested 40, a detection device 50 and a control device (not shown). The automated testing system 100 is used to test the performance of a pump source module 42 in the device to be tested 40. For example, the automated testing system 100 can be used to test the numerical aperture (NA value) of the pump source module 42, the divergence angle of the exit light of the pump source module 42, the overall power of the pump source module 42, the temperature of the pump source module 42 and other parameters.
[0043] The fixing device 10 is used to provide a platform for carrying other supporting bodies, and the platform can be set as the ground or other flat surfaces.
[0044] The rotating device 20 is rotatably disposed on the fixing device 10. The rotating device 20 can rotate 360° clockwise or counterclockwise, and the speed during the rotation process is controllable, and there is a pause point during the rotation process.
[0045] The clamping device 30 is disposed on the rotating device 20, and is used to clamp or release the device to be tested 40, and the device to be tested 40 includes a pump source module 42. During the rotation of the rotating device 20, the clamping device 30 can be carried to move to different positions.
[0046] The detection device 50 is disposed on the fixing device 10 . When the clamping device 30 moves to the testing station, the detection device 50 performs detection on the pump source module 42 .
[0047] The control device is electrically connected to the rotating device 20, the clamping device 30 and the detection device 50. The control device is configured to control the rotating device 20 to rotate so that the clamping device 30 is in a preset position; the control device is configured to control the clamping device 30 to perform a preset action when the rotating device 20 drives the clamping device 30 to be in different preset positions; the control device is configured to control the detection device 50 to test the performance of the pump source module 42.
[0048] In this embodiment, the key steps of the performance test of the pump source module 42 include: the rotating device 20 rotates to make the clamping device 30 in a preset position; when the rotating device 20 drives the clamping device 30 to be in the preset position, the clamping device 30 is controlled to perform a preset action; the detection device 50 tests the performance of the pump source module 42.

[0049] In one embodiment, see Figure 4 and Figure 5 The rotating device 20 has M positions during the rotation process, where M is a positive integer, 3≤M≤6. The preset positions at least include: a clamping position, a releasing position, and a testing position. The preset actions include: clamping, powering on, and releasing.
[0050] The clamping device 30 includes: M clamping bodies 31 and a clamping power-on component 32. The M clamping bodies 31 are respectively arranged on the rotating device 20, and when one of the clamping bodies 31 is in one of the preset workstations, the other M-1 clamping bodies 31 are in the other M-1 preset workstations. It can be understood that the M clamping bodies 31 are arranged at intervals within the rotation cycle of the rotating device 20, for example, they can be arranged at equal intervals. Correspondingly, when the device to be tested 40 switches from one workstation to another adjacent workstation, the control device is configured to control the rotating shaft 21 to rotate a°, so that the two rotating wheels 22 rotate a°, and the M clamping bodies 31 arranged on the connecting rod 23 will also rotate a°, where a°=360° / M.
[0051] The clamp power-on component 32 is disposed on the fixing device 10 . The clamp power-on component 32 is disposed near the detection device 50 .

For example, when one clamping body 31 is in the clamping position, the control device controls the clamping body 31 to clamp the device to be tested 40; when another clamping body 31 is in the testing position, the control device controls the clamping power-on component 32 to contact the device to be tested 40, so that the clamping power-on component 32 powers on the pump source module 42; when another clamping body 31 is in the releasing position, the control device controls the clamping body 31 to release the device to be tested 40.
[0053] In this embodiment, the key steps of the performance test of the pump source module 42 include: the clamp body 31 clamps the device to be tested 40, the clamp power-on component 32 powers the device to be tested 40, the detection device 50 performs a performance test on the pump source module 42, and the clamp body 31 releases the device to be tested 40. The above key steps can all be automatically controlled by the control device, and the above key steps do not rely on manual operation, which reduces labor costs and can ensure the consistency and accuracy of the measurement results.
[0054] The clamping device 30 includes: M clamping bodies 31 and clamping power-on components 32, where M is at least 3; the rotating device 20 has at least 3 stations during the rotation process, such as a clamping station, a test station, and a release station. The rotating device 20 stays at each station for a certain period of time to complete different actions on the device to be tested 40. In this embodiment, the clamping device 30 implements the two key actions of clamping (clamping or releasing) and power-on in two steps. On the one hand, when clamping the material, there is no need to consider the power-on action, which can improve the efficiency of loading; on the other hand, it can ensure that the device to be tested 40 is completely located at the test station before power-on and subsequent performance testing are performed, which can effectively improve the initial position of the device to be tested 40 during the performance test, minimize the position movement of the detection device 50, and improve the test efficiency.

The two first supports 11 spaced apart are fixedly arranged on both sides of the platform 10a. The fixing platform 10a can be set to the ground or other flat surfaces. The rotating device 20 includes: a rotating shaft 21, two rotating wheels 22 and M connecting rods 23.
[0056] The rotating shaft 21 is rotatably disposed between the two first support bodies 11. Two rotating wheels 22 are fixedly disposed on the rotating shaft 21 and are spaced apart, and the two rotating wheels 22 are respectively located on the inner sides of the two first support bodies 11. M connecting rods 23 are provided, and the connecting rods 23 are fixed between the two rotating wheels 22. Specifically, one end of the connecting rod 23 is fixed on the inner side of one rotating wheel 22, and the other end of the connecting rod 23 is fixed on the inner side of the other rotating wheel 22; one connecting rod 23 is provided with a clamping body 31. The control device is configured to control the rotating shaft 21 to rotate 360°, so that the two rotating wheels 22 rotate 360°, and the M clamping bodies 31 provided on the connecting rod 23 also rotate 360°.
[0057] The present embodiment also includes the following specific embodiments: when M is 3, the angle between the lines connecting two adjacent connecting rods 23 and the rotating shaft 21 is 120°; whenever the rotating device 20 rotates 120°, the clamp body 31 moves from one station to the next station. When M is 4, the angle between the lines connecting two adjacent connecting rods 23 and the rotating shaft 21 is 90°; whenever the rotating device 20 rotates 90°, the clamp body 31 moves from one station to the next station. When M is 5, the angle between the lines connecting two adjacent connecting rods 23 and the rotating shaft 21 is 72°; whenever the rotating device 20 rotates 72°, the clamp body 31 moves from one station to the next station. When M is 6, the angle between the lines connecting two adjacent connecting rods 23 and the rotating shaft 21 is 60°; whenever the rotating device 20 rotates 60°, the clamp body 31 moves from one station to the next station.
[0058] In the above embodiment when M is 4, the rotating device 20 has 4 stations during the rotation process, which can be respectively set as: a clamping station, an identification station, a test station and a release station. In the above embodiment when M is 5, the rotating device 20 has 5 stations during the rotation process, which can be respectively set as: a clamping station, an identification station, a first test station, a second test station and a release station. In the above embodiment when M is 6, the rotating device 20 has 6 stations during the rotation process, which can be respectively set as: a clamping station, an identification station, a first test station, a second test station, a determination station and a release station. In the above specific embodiment of M=5 or 6, the first test station and the second test station are respectively used to test the performance of the pump source module 42, and the control device obtains and analyzes the test results at the two test stations, and finally determines the performance parameters of the pump source module 42. In the above-mentioned specific embodiment of M=6, if the test results at the two test stations are different, the pump source module 42 enters the determination station again to perform a new determination operation, and the specific determination operation may include testing other parameters to provide feedback from the side whether the test results of the two test stations are credible. Alternatively, if the test results at the two test stations are the same, but both do not meet the preset performance of the pump source module 42, then the determination station is entered again to determine whether the pump source module 42 is damaged.
[0059] In addition, in the above embodiment when M is 6, the rotating device 20 has 6 stations during the rotation process, which can be respectively set as: a clamping station, an identification station, a first test station, a second test station, a third test station and a release station. When three test stations are set, three sets of detection devices 50 need to be set accordingly to realize the testing of different test stations.
[0060] In this embodiment, the specific structure of the rotating device 20 is detailed, as well as various achievable structures of setting different numbers of clamping bodies 31 on the rotating device 20. The structure of the automated testing system 100 in this application can be flexibly adjusted according to specific testing requirements. In this embodiment, no matter how the structures of the rotating device 20 and the clamping device 30 are adjusted, full-process automated, high-precision, and high-accuracy performance testing can be achieved.
[0061] In one embodiment, see Figure 5 , Figure 6 , Figure 7 and Figure 8 The clamp body 31 includes: a first connecting member 311, a first clamping plate 312, a second clamping plate 313, a second connecting member 314 and two mobile clamping mechanisms 315.
[0062] The first connecting member 311 is connected to the connecting rod 23. In one specific embodiment, the first connecting member 311 is fixedly connected to the connecting rod 23. In another specific embodiment, the first connecting member 311 is movably connected to the connecting rod 23. The first connecting member 311 can be configured to be connected with an oil-free bushing or a self-lubricating bearing. The first connecting member 311 is in a semi-fixed connection with the connecting rod 23, and the clamp body 31 can be damped relative to the connecting rod 23, so that during the rotational movement, the clamp body 31 is under the connecting rod 23 due to the action of gravity, and the movement range of the clamp body 31 is small and relatively controllable.
[0063] The first clamping plate 312 is fixedly connected to the first connecting member 311. The second clamping plate 313 is fixedly connected to the first connecting member 311. The first clamping plate 312 and the second clamping plate 313 have parallel opposite surfaces. The distance between the first clamping plate 312 and the second clamping plate 313 is less than the length of the connecting rod 23.
[0064] The second connecting member 314 is fixedly connected between the first clamping plate 312 and the second clamping plate 313. Two mobile clamping mechanisms 315 are movably arranged on the first clamping plate 312 and the second clamping plate 313 respectively. The mobile clamping mechanism 315 can extend into the clamping space formed by the first clamping plate 312 and the second clamping plate 313. The mobile clamping mechanism 315 is used to clamp the device to be tested 40. The two mobile clamping mechanisms 315 clamp the device to be tested 40 at the same time or release the device to be tested 40 at the same time.
[0065] In this embodiment, the structure of the clamp body 31 is refined. On the one hand, the structure can simply and efficiently realize the function of clamping or releasing the device under test 40; on the other hand, the structure can realize interaction with the connecting rod 23 and is convenient to stop at different workstations for automated testing. In one embodiment, see Figure 5 , Figure 6 , Figure 7 and Figure 8 The first clamping plate 312 and the second clamping plate 313 both include: a first opening 31a and a first through hole (not shown). Figure 5 As shown, the first through holes include two holes spaced apart from each other, both of which are filled with positioning pins 315c.
[0066] The mobile clamping mechanism 315 includes: a driving member 315a, a positioning member body 315b and a positioning pin 315c. The driving member 315a is movably arranged at the first opening 31a. The positioning member body 315b is respectively arranged on the outer side walls of the first clamping plate 312 and the second clamping plate 313. The positioning pin 315c is fixedly connected to the positioning member body 315b.
[0067] The driving member 315a drives the positioning member body 315b to move along the Y-axis direction, so that the positioning pin 315c passes through the first through hole and is exposed in the clamping space. The clamping space is the space between the first clamping plate 312 and the second clamping plate 313 which are arranged parallel to each other, and the Y-axis direction is perpendicular to the extension direction of the side of the first clamping plate 312. In this embodiment, the specific structure of the mobile clamping mechanism 315 is refined, and the driving member 315a drives the positioning member body 315b and the positioning pin 315c to move along the Y-axis direction into the clamping space to realize the function of clamping the device to be tested 40.
[0068] In one embodiment, see Fig. 9 and Fig.10 The driving member 315a is a driving cylinder. The mobile clamping mechanism 315 also includes a driving auxiliary member 3150. The driving auxiliary member 3150 includes an air source 3151, M electromagnetic valves 3152, a gas-electric integrated slip ring 3153 and a gas pipeline 3154.
[0069] The gas source 3151 is used to provide driving gas, and its location is not specifically limited as long as it does not hinder the rotation device 20 from driving the clamping device 30 to move.
[0070] The electromagnetic valve 3152 is connected to the gas source 3151 through a pipeline, and is used to control the flow rate of the gas in the pipeline and the flow direction of the gas. The electromagnetic valve 3152 is bidirectional, that is, it can be opened and closed in both directions. Figure 1 In the illustrated embodiment, when M=4, four solenoid valves 3152 are provided.
[0071] The gas-electric integrated slip ring 3153 is arranged at one end of the rotating shaft 21. The gas-electric integrated slip ring 3153 has a moving shaft 3153b and a fixed shaft 3153a, and both the moving shaft 3153b and the fixed shaft 3153a have M groups of gas ports. Relative to the fixed shaft 3153a, the moving shaft 3153b is arranged on the inner side of the rotating shaft 21. Relative to the moving shaft 3153b, the fixed shaft 3153a is arranged on the outer side of the rotating shaft 21. The moving shaft 3153b can rotate with the rotation of the rotating shaft 21. Fig. 9 and Fig.10 The moving shaft 3153b and the fixed shaft 3153a of the gas-electric integrated slip ring 3153 shown have four groups of gas ports, and the four groups of gas ports are arranged between the moving shaft and the fixed shaft to allow gas to pass through.
[0072] The gas pipeline 3154 connects the gas source 3151 with the electromagnetic valve 3152, the electromagnetic valve 3152 with the gas port on the fixed shaft 3153a, and the gas port on the movable shaft 3153b with the driving cylinder. The gas pipeline 3154 can be tied to the rotating wheel 22 or the connecting rod 23 and other structures by a strap.
[0073] like Fig. 9It is a schematic diagram showing that a driving cylinder (driving member 315 a ) provided on two clamping plates provided on the same clamping body 31 drives a positioning member body 315 b and a positioning pin 315 c to clamp the device to be tested 40 . Fig. 9 In the embodiment, the gas in the gas source 3151 enters the gas pipeline 3154, and when the first solenoid valve is opened in the first direction, the gas enters from the a1 port of the fixed shaft, passes through the moving shaft 3153b, and flows out from the b1 port of the moving shaft 3153b, flows through the driving member 315a in the two clamping plates (the first clamping plate 312 and the second clamping plate 313), and then enters from the b5 port, passes through the fixed shaft 3153a, and flows out from the a5 port of the fixed shaft 3153a, and returns to the first solenoid valve. The driving member 315a drives the positioning member body 315b and the positioning pin 315c to clamp the device to be tested 40.
[0074] The first solenoid valve Fig.10 It is a principle diagram showing that a driving cylinder (driving member 315 a ) provided on two clamping plates provided on the same clamping body 31 drives a positioning member body 315 b and a positioning pin 315 c to release the device to be tested 40 . Fig.10 In the embodiment, the gas in the gas source 3151 enters the gas pipeline 3154, and when the first solenoid valve is opened in the second direction, the gas enters from the a5 port of the fixed shaft 3153a, passes through the moving shaft 3153b, and flows out from the b5 port of the moving shaft 3153b, flows through the driving member 315a in the two clamping plates, and then enters from the b1 port, passes through the fixed shaft 3153a, and flows out from the a1 port of the fixed shaft 3153a, and returns to the first solenoid valve. The driving member 315a drives the positioning member body 315b and the positioning pin 315c to release the device to be tested 40.
[0075] In this embodiment, the driving auxiliary member 3150 is used to assist in driving the positioning member body 315b and the positioning pin 315c to clamp and release the device to be tested 40. On the one hand, the operating principle of the driving auxiliary member 3150 is simple, and the solenoid valve 3152 allows the direction of gas flow to be controllable; on the other hand, the gas-electric integrated slip ring 3153 can effectively control the setting position of the gas pipeline 3154 to prevent the gas pipeline 3154 from moving or rotating, thereby affecting the movement of the rotating device 20.
[0076] In one embodiment, the clamping and powering component 32 is movably disposed on the first support body 11. When the clamping body 31 clamps the device under test 40 and moves to the test station, the clamping and powering component 32 clamps the device under test 40 and powers the device under test 40. In this embodiment, the height of the clamping and powering component 32 in the Z-axis direction is adapted to the height of the device under test 40 when it moves to the test station, that is, it can achieve clamping and powering.
[0077] In one embodiment, see Fig.11The device to be tested 40 includes: a test chamber 41, a pump source module 42 and an optical fiber module 43.
[0078] The test chamber 41 can provide a storage space. The pump source module 42 is arranged in the test chamber 41, and when the clamping device 30 powers on the pump source module 42, a laser is emitted. The optical fiber module 43 includes an optical fiber reel 402 and an optical fiber coiled on the optical fiber reel 402. One end of the optical fiber is connected to the light outlet hole of the pump source module 42, and the other end of the optical fiber passes through the side wall of the test chamber 41, and is used to transmit the laser to be tested to the outside. In this embodiment, the test chamber 41 accommodates the pump source module 42 and the optical fiber module 43. The optical fiber module 43 can be coiled and will not shake during the test, which will not affect the test results. The flange joint of the optical fiber module 43 is arranged on the outside of the test chamber 41, and the contact position between the optical fiber module 43 and the pump source module 42 is the optical fiber nozzle. The temperature of the optical fiber nozzle can be monitored.
[0079] In one embodiment, see Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.15 The test chamber 41 includes: a bottom wall 401, a first side wall 411, and a second side wall 412. Fig.12 As shown, the bottom wall 401 is provided with a limit block 403. The limit block 403 is used to limit the movement of the pump source module 42.
[0080] The first side wall 411 is vertically disposed on the bottom wall 401. The first side wall 411 is provided with a second opening 411a for accommodating electrodes of the pump source module 42. The electrodes disposed in the second opening 411a may include positive and negative electrical pins.
[0081] The second side wall 412 is vertically disposed on the bottom wall 401 and is spaced apart from and parallel to the first side wall 411. The second side wall 412 is provided with a through hole 412a that allows the optical fiber module 43 to pass through; wherein, both the first side wall 411 and the second side wall 412 have a clamping hole 411b, and the positioning pin 315c can extend into the clamping hole 411b to facilitate the movement of the clamping mechanism 315 to clamp or release the device under test 40. When the pump source module 42 is installed in the test chamber 41, the height of the clamping hole 411b in the Z-axis direction is higher than the height of the electrode of the pump source module 42 in the Z-axis direction.
[0082] The optical fiber disc 402 is protruding from the bottom wall 401 and is disposed close to the second side wall 412 . After the optical fiber is led out from the light outlet hole of the pump source module 42 , it is coiled at the optical fiber disc 402 and then led out through the through hole 412 a of the second side wall 412 .
[0083] In this embodiment, the test chamber 41 further includes: a third side wall 413 and a fourth side wall 414. The third side wall 413 is vertically arranged on the bottom wall 401, and has a connection portion with the first side wall 411 and the second side wall 412 respectively. The fourth side wall 414 is vertically arranged on the bottom wall 401, and has a connection portion with the first side wall 411 and the second side wall 412 respectively. Compared with the fourth side wall 414, the third side wall 413 is closer to the pump source module 42. The third side wall 413 is provided with an observation window 413a for observing the product information of the pump source module 42 (the product information may be a QR code information showing the pump source product). The bottom wall 401, the first side wall 411, the second side wall 412, the third side wall 413, and the fourth side wall 414 may be integrally formed.
[0084] In one embodiment, see Fig.14 The pump source module 42 includes: a pump unit 421 , a TC cooling plate 422 and a heat dissipation fin 423 .
[0085] The pump unit 421 includes one or more semiconductor laser chips. The pump unit 421 has positive and negative electrical pins. The TC cooling plate 422 is embedded in the bottom wall 401 and contacts the pump unit 421. The TC cooling plate 422 has positive and negative electrical pins. The pump unit 421 is arranged above the TC cooling plate 422 in the Z-axis direction. The heat dissipation fins 423 contact the TC cooling plate 422 and cover the outer side of the bottom wall 401.
[0086] In this embodiment, a heat dissipation structure is provided in the pump source module 42 to achieve heat dissipation for the pump unit 421 , thereby reducing unnecessary damage to the pump unit 421 during the test process.
[0087] In one embodiment, see Figure 4 The outer side of the connection between any two side walls of the test chamber 41 has an outer chamfer. In a specific embodiment, the outer chamfer can be set to 30°-45°.

The first power-on contact 322 is disposed in the receiving portion 321a, and is used to be electrically connected to the TC refrigeration plate 422. The second power-on contact 323 is disposed above the receiving portion 321a along the Z axis direction, and is used to be electrically connected to the pumping unit 421. The first power-on contact 322 and the second power-on contact 323 respectively include a positive power-on terminal and a negative power-on contact.
[0089] In this embodiment, the arrangement of the clamping power supply assembly 32 can, on the one hand, more conveniently realize the power supply of the pump unit 421; on the other hand, while the pump unit 421 is powered, the TC cooling plate 422 is also powered, which can dissipate heat for the pump unit 421 in a more timely manner.
[0090] In one embodiment, see Fig.16 and Fig.17 The detection device 50 includes: an aperture retaining ring 51 and a power meter 52.
[0091] The aperture retaining ring 51 is disposed on the fixture 10 and can move along the X-axis, the Y-axis and the Z-axis. The power meter 52 is disposed on the fixture 10 and is away from the aperture retaining ring 51 in the Y-axis direction. The outgoing light of the device to be tested 40 passes through the aperture retaining ring 51 and then irradiates the power meter 52.
[0092] In this embodiment, the aperture clamp ring 51 can be moved along the X-axis, Y-axis and Z-axis directions by a three-axis translation stage / three-axis motor. The position adjustment of the aperture clamp ring 51 facilitates improving the accuracy of the performance detection of the pump source module 42.
[0093] In one embodiment, the detection device 50 further includes: a second identification device 53 disposed on an outer side wall of the first clamping plate 312 or the second clamping plate 313. Further, the second identification device 53 is disposed on one side of the detection device 50. In this embodiment, the second recognition device 53 can be set as a visual camera with a fisheye function. The second recognition device 53 is used to obtain the contour of the aperture clamp 51, and to obtain the contour of the exit light of the pump source module 42 to be tested irradiated on the aperture clamp 51. The second recognition device 53 transmits the detection results of the two contours to the control device for analysis, so as to realize the concentricity detection of the contour of the aperture clamp 51 and the contour of the exit light of the pump source module 42 to be tested irradiated on the aperture clamp 51, so as to improve the accuracy of the performance detection of the pump source module 42.
[0094] In one embodiment, the detection device further includes: a temperature monitoring module 54. The temperature monitoring module 54 is disposed on the platform 10a and is used to monitor the temperature change at the connection between the pump source module 42 and the optical fiber module 43.
[0095] In this embodiment, the temperature monitoring module 54 can be arranged at a position directly opposite to the connection between the pump source module 42 and the optical fiber nozzle of the optical fiber module 43. The temperature monitoring module 54 can be arranged above the cover plate of the pump unit 421, or other positions that are prone to temperature changes. The temperature monitoring module 54 can be set as a temperature sensor, such as an infrared thermal imager, for monitoring the temperature at the connection between the pump source module 42 and the optical fiber module 43, and transmitting the temperature change value to the control device. The control device can implement emergency stop control according to the temperature change.
[0096] In one embodiment, see Fig.18 and Fig.19 The automated testing system further comprises: a loading device 60 disposed on the platform 10 a. The loading device 60 comprises: a loading crawler 61 , a motion cutoff portion 62 and a proximity switch 63 .
[0097] The feeding crawler 61 is arranged on the platform 10a and can be driven along the X-axis to convey the device to be tested 40. The running speed of the feeding crawler 61 is adjusted by the control device.
[0098] The motion cutoff portion 62 is arranged at the end point of the feeding crawler 61 along the X-axis, and the height of the motion cutoff portion 62 in the Z-axis direction is higher than the height of the feeding crawler 61 in the Z-axis direction. The proximity switch 63 is arranged at the motion cutoff portion 62, and is used to sense whether the device to be tested 40 is close to the preset feeding position. The feeding crawler drive shaft 66 is arranged below the motion cutoff portion 62, and is used to drive the feeding crawler 61 to move.
[0099] In the present embodiment, an automated loading device 60 is provided. On the one hand, the loading device 60 is arranged below the rotating device 20, and does not affect the rotation of the rotating device 20 carrying the clamping body 31 between different workstations; on the other hand, the device to be tested 40 to be loaded can be loaded when it runs to the motion cutoff part 62 in the transmission of the loading crawler 61, and the loading process can be seamlessly connected.
[0100] In one embodiment, see Fig. 20 , the outer wall of the first clamping plate 312 or the outer wall of the second clamping plate 313 is provided with a contact piece 31b. The feeding device 60 also includes: a photoelectric sensor 64, which is arranged on the inner wall of the first support body 11, and is used to sense whether a clamping body 31 runs to the feeding position. The photoelectric sensor 64 is arranged at a corresponding height on the first support body 11. The height of the photoelectric sensor 64 in the Z-axis direction corresponds to the height of the contact piece 31b in the clamping body 31 that moves to the clamping station in the Z-axis direction. When a clamping body 31 just runs to the feeding position, the contact piece 31b will trigger the photoelectric sensor 64. When the control device receives that the photoelectric sensor 64 is triggered, the control device can send a feeding operation instruction.
[0101] In one embodiment, when the photoelectric sensor 64 senses through the contact piece 31b that the clamp body 31 has moved to the loading position, and the proximity switch 63 senses that the device to be tested 40 is approaching the loading position, the control device can send a loading operation instruction, and the loading operation instruction controls the two mobile clamping mechanisms 315 to clamp the device to be tested 40 at the same time.
[0102] In this embodiment, the loading operation is restricted by two operating conditions. The conditions for issuing the loading operation instruction are more stringent, and the probability of misaligned clamping is lower. While realizing automatic loading, the device to be tested 40 is protected to the greatest extent.
[0103] In one embodiment, the feeding device 60 further includes: a positioning assembly 65, which is arranged on both sides of the feeding crawler 61. The positioning assembly 65 is in a closed shape, and the closer to the motion cutoff portion 62 in the X-axis direction, the smaller the size is, and the minimum size is equal to the outer edge size of the device under test 40.
[0104] In this embodiment, the arrangement of the alignment component 65 can automatically adjust the placement position of the device to be tested 40 on the feeding track 61, thereby reducing the occurrence of misalignment of the clamp during feeding.
[0105] In one embodiment, see Fig.21 The automated testing system 100 further includes a material unloading device 70 disposed on the platform 10 a. The material unloading device 70 includes a supporting member 71 and a material unloading crawler 72 .
[0106] The supporting member 71 is rotatably and liftably disposed on the platform 10a, and is used to support the device to be tested 40 that has completed the test. The unloading crawler 72 is disposed on the platform 10a, and can be driven along the X-axis, and is used to transport the device to be tested 40 that has completed the test.
[0107] In this embodiment, the supporting member 71 is located at the release position. When the clamping device 30 clamps the device that has completed the test and runs to the release position, the clamping device 30 releases the device to be tested 40 that has completed the test, and the supporting member 71 supports the device to be tested 40 that has completed the test to rotate to the side. At the same time, the clamping device 30 is driven by the rotating device 20 to rotate to the loading position. The supporting member 71 supports the device to be tested 40 that has completed the test to the unloading crawler 72 for unloading. In this embodiment, the supporting member 71 can be raised and lowered and rotated, which is convenient for unloading operations, and does not affect the rotating device 20 driving the clamping device 30 to rotate to the loading position, thereby improving the operating efficiency of the system.
[0108] In one embodiment, see Fig.21 The unloading crawler 72 includes two crawlers arranged at intervals, such as Fig.21 The first material unloading crawler 72a and the second material unloading crawler 72b are shown in FIG. The interval between the two material unloading crawlers is equal to the width of the supporting surface of the supporting member 71. The length of the supporting surface of the supporting member 71 is greater than or equal to the width of the test chamber.
[0109] In this embodiment, a first unloading track 72a and a second unloading track 72b are provided to facilitate the support member 71 to place the tested device 40 after the test is completed, and at the same time ensure that during the unloading process, the tested device 40 after the test is completed will not encounter any accidents (such as bumping or overturning).
[0110] The present application also provides an automated testing method, which is applied to any of the automated testing systems 100 described above. The automated testing method includes: S10, the control device controls the clamping device 30 to clamp the device to be tested 40 at the clamping station.

[0112] S30, when the clamping device 30 on the rotating device 20 is in the testing position, the control device controls the clamping device 30 to power on the device to be tested 40, and controls the detection device 50 to test the performance of the pump source module 42. When the test is completed, the clamping device 30 is controlled to stop powering on the device to be tested 40.
[0113] S40, the control device controls the clamping device 30 to release the device to be tested 40 at the release station.
[0114] In one embodiment, the automated testing system 100 further includes a first identification device 80, and the automated testing system 100 also has an identification station during operation. The automated testing method further includes: when the clamping device 30 on the rotating device 20 is in the identification station, the control device controls the first identification device 80 to identify parameter information of the device to be tested 40, and saves it to the control device.
[0115] In one embodiment, the automated testing system further includes a feeding device 60. The feeding device 60 includes: a feeding crawler 61, a motion cutoff portion 62, and a proximity switch 63. The automated testing method further includes: when the clamping device 30 moves to the feeding position, and the proximity switch 63 senses that the device to be tested 40 is close to the feeding position, the control device controls the clamping device 30 to clamp the device to be tested 40.

The automated testing method further includes: the control device controls the supporting member 71 to be located at the feeding position, when the clamping device 30 clamps the device that has completed the test and runs to the feeding position, the control device controls the clamping device 30 to release the device that has completed the test, and the control device controls the supporting member 71 to support the device to be tested 40 that has completed the test and rotate to the side, and at the same time, the clamping device 30 is driven by the rotating device 20 to rotate to the loading position to load the next device to be tested 40.
[0117] like Figure 1In the illustrated embodiment, the automated testing system 100 further includes: a first identification device 80. The clamping device 30 includes: a clamping power-on assembly 32 and four clamping bodies 31. The rotating device 20 has four stations during the rotation process, namely, a clamping station, an identification station, a testing station and a releasing station, which are sequentially arranged in a counterclockwise direction.
[0118] The four clamping bodies 31 are respectively disposed on the rotating device 20 , and when one of the clamping bodies 31 is located at the clamping station, the other three clamping bodies 31 are respectively located at the identification station, the testing station and the releasing station.
[0119] The control device is configured as follows: when the clamp body 31 is located at the clamping position, the clamp body 31 is controlled to clamp the device to be tested 40; when the clamp body 31 is located at the identification position, the first identification device 80 is controlled to identify the parameter information of the device to be tested 40; when the clamp body 31 is located at the testing position, the clamp power-on component 32 is controlled to power on the device to be tested 40; when the clamp body 31 is located at the releasing position, the clamp body 31 is controlled to release the device to be tested 40.
[0120] like Fig.18 , Fig.19 , Fig. 20 As shown, the rotation device 20 stops at the clamping station for 1 second to 2 seconds, which is used to load the device to be tested 40 to the clamp body 31, and the pump source module 42 to be tested is loaded in the device to be tested 40. Fig.19 The proximity switch 63 shown confirms the position of the device under test 40 by Fig. 20 The photoelectric sensor 64 shown confirms the position of the clamp body 31. When the device to be tested 40 and the clamp body 31 are in place, the two mobile clamp mechanisms 315 clamp at the same time to complete the loading operation.
[0121] The rotating device 20 rotates counterclockwise by 90°, and the clamp body 31 that has completed loading stops at the identification station for 1 second to 2 seconds to identify the product information (product model, product identification code, etc.) of the pump source module 42 to be tested in the device to be tested 40. Fig.11 The side wall of the test chamber 41 fixed with the pump source module 42 is provided with an observation window 413a, and the product information of the pump source module 42 can be set as a QR code and exposed at the observation window 413a. Fig.18 The first identification device 80 shown takes a picture of the observation window 413a and transmits the picture result to the control device, which parses the QR code information to obtain the product information of the pump source module 42. The control device can also call a corresponding test program according to the product information of the pump source module 42.
[0122] The rotating device 20 rotates counterclockwise by 90°, and the pump source module to be tested, which has identified the product information, moves to the test station. The clamp body 31 stops at the test station for about 1 minute to 2 minutes to complete the performance test of the pump source module 42. When the clamp body 31 clamps the device to be tested 40 to the test station, Figure 4 The clamping power-on assembly 32 shown will power the pump source module 42. Specifically, the power-on body 321 is in the negative direction along the Y axis ( Figure 4 The control device controls the clamp power-on assembly 32 to power the pump unit 421. The control device controls the detection device 50 to open, and detects parameters such as the NA value of the pump source module 42, the divergence angle of the exit light of the pump source module 42, the overall power of the pump source module 42, and the temperature of the pump source module. When the power test is completed, the power-on body 321 is controlled to move in the positive direction along the Y axis until the clamp power-on assembly 32 is completely away from the clamp body 31 (without affecting the rotation of the rotating device 20, that is, the clamp power-on assembly 32 will not touch the clamp body 31 or the device to be tested 40).
[0123] The rotating device 20 rotates counterclockwise by 90°, and the pump source module 42 that has completed the test moves to the release position, and the pause time at the release position is about 1 second to 2 seconds. Fig.21 As shown, the supporting member 71 in the unloading device 70 supports the device to be tested 40 that has completed the test, and the clamping body 31 releases the device to be tested 40 that has completed the test. The control device controls the supporting member 71 to support the device to be tested 40 that has completed the test and to rotate the supporting member 71 to a position where it does not touch the rotating device 20 after descending a certain distance; the control device controls the supporting member 71 to rise to a position higher than the unloading crawler 72, and the control device further controls the supporting member 71 to rotate to a position corresponding to the gap formed by the supporting member 71 and the first unloading crawler 72a and the second unloading crawler 72b; the control device further controls the supporting member 71 to descend until the device to be tested 40 that has completed the test is placed on the unloading crawler 72 to complete the unloading operation.
