Such equipment mainly includes a linear motor slide rail and a diaphragm. In the operation process, manual intervention is an essential part, including that the operators in the early stage need to receive on-the-job training for various test steps; before the actual measurement, it is necessary to manually untangle the coiled optical fiber and correctly insert the optical fiber into the flange; add an appropriate amount of cooling water between the module to be tested and the water cooling plate and other preparatory work; the operator manually loads and unloads, the operator measures the temperature on-site, and the operator manually determines the interference factors. In terms of automatic control, although the existing pump source module performance testing systems and testing methods can achieve a certain degree of automation, some key steps still rely on manual operation, increasing the labor cost and making it difficult to ensure the consistency and accuracy of the measurement results.
[0003] The traditional semi-automatic measurement method cannot achieve automated and full-process performance testing, cannot achieve reasonable, safe and labor-saving operation steps and details, cannot shorten the operation time, and cannot improve the testing efficiency of the pump source module performance testing.

[0086] 1.

The key steps for the automated test system to perform a performance test on the pump source module include: the clamping device clamps the device under test, the clamping device powers on the device under test, the detecting device performs a performance test on the pump source module, and the clamping device releases the device under test. The above key steps can all be automatically controlled by the controller. The above key steps do not rely on manual operation, reducing labor costs and ensuring the consistency and accuracy of the measurement results.
[0087] 2.1. In the embodiment of the present application, the clamping device realizes the two key actions of clamping (clamping or releasing) and powering on in two steps. On the one hand, when loading and clamping, there is no need to consider the powering-on action, which can improve the efficiency during loading; on the other hand, it can ensure that after the device under test is completely located at the test station, powering on and subsequent performance tests are performed, which can effectively reduce the position movement of the device under test during the performance test and improve the test efficiency.
[0088] 2.2. In the embodiment of the present application, the structure of the automated test system can be flexibly adjusted according to specific test requirements. By setting different numbers of clamping body on the rotating device, different automated test systems can be realized.

On the one hand, the operating principle of the driving auxiliary part is simple, and the solenoid valve enables the direction of gas flow to be controllable; on the other hand, an air-electric integrated slip ring can effectively control the installation position of the gas pipeline to prevent the gas pipeline from moving or rotating, thereby affecting the movement of the rotating device.
[0091] 2.5. In the embodiment of the present application, a clamping power supply component is also provided. On the one hand, it can more conveniently realize the power supply of the pump unit; on the other hand, while the pump unit is powered, the TC cooling plate is also powered, and the pump unit can be cooled more timely.
[0092] 3. In the embodiment of the present application, the device to be tested includes a test chamber for accommodating a pump source module and an optical fiber module. The optical fiber module can be coiled and arranged, and there will be no shaking during the test process, which will not affect the test results. An outer chamfer is provided on the outer side wall of the test chamber to facilitate the clamping of the pump source module. A heat dissipation structure is provided in the pump source module to realize the heat dissipation of the pump source module, which can reduce unnecessary damage to the pump element module during the test process.
[0093] 4. In the embodiment of the present application, a second recognition device is further included to obtain the contour of the diaphragm retaining ring and the contour of the outgoing light of the pump source module to be tested irradiating on the diaphragm retaining ring. The second recognition device transmits the detection results of the two contours to the control device for analysis to realize the concentricity detection of the contour of the diaphragm retaining ring and the contour of the outgoing light of the pump source module to be tested irradiating on the diaphragm retaining ring, which is convenient to improve the accuracy of the performance detection of the pump source module.
[0094] 5. The embodiment of the present application further includes a temperature monitoring module, which can be set at a position directly opposite to the connection of the fiber nozzle of the pump source module and the fiber module. The temperature monitoring module can be set above the cover plate of the pump unit or other positions where temperature changes are likely to occur. The temperature monitoring module is used to monitor the temperature change at the connection of the pump source module and the 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 situation.
[0095] 6. The embodiment of the present application further includes an automated feeding device. On the one hand, the feeding 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 to be fed can perform the feeding operation when it runs to the movement stop part during the transmission of the feeding track, and its feeding process can achieve seamless connection.
[0096] 7. The embodiment of the present application further includes an automated discharging device. The discharging device includes a supporting member and a discharging track. The supporting member can be lifted and rotated, which is convenient for discharging operations and does not affect the rotating device to drive the clamping device to rotate to the feeding position at the same time, improving the operation efficiency of the system. The discharging track can include two tracks arranged at intervals, which is convenient for the supporting member to place the device to be tested that has completed the test, and can ensure that the device to be tested that has completed the test will not have accidents (such as being knocked or overturned) during the discharging process.

[0137] The fixing device 10 is used to provide a platform for carrying other supports, and this platform can be set as the ground or other flat surfaces.
[0138] The rotating device 20 is rotatably arranged on the fixing device 10. The rotating device 20 can rotate 360° clockwise or counterclockwise, and the speed during the rotation is controllable, and there are stop points during the rotation.
[0139] The clamping device 30 is arranged on the rotating device 20 and is used to clamp or release the device under test 40, and the device under test 40 includes a pump source module 42.

The rotating device 20 stays at each station for a certain period of time to complete different actions on the device under test 40. In this embodiment, the clamping device 30 realizes the two key actions of clamping (clamping or releasing) and power-on in two steps. On the one hand, when loading and clamping, the efficiency during loading can be improved without considering the power-on action; on the other hand, it can be ensured that after the device under test 40 is completely located at the testing station, power-on and subsequent performance testing are carried out, which can effectively improve the initial position of the device under test 40 during performance testing, minimize the position movement of the detection device 50 as much as possible, and improve the testing efficiency.
[0149] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 4 , the fixing device 10 includes: a platform 10a and two first supports 11 arranged at intervals. The two first supports 11 arranged at intervals are respectively fixedly arranged on both sides of the platform 10a. The fixed platform 10a can be set as the ground or other flat surfaces. The rotating device 20 includes: a rotating shaft 21, two runners 22, and M connecting rods 23.
[0150] The rotating shaft 21 is rotatably arranged between the two first supports 11. The two runners 22 are fixedly arranged on the rotating shaft 21, and the two runners 22 are arranged at intervals, and the two runners 22 are respectively located inside the two first supports 11. There are M connecting rods 23, and the connecting rods 23 are fixed between the two runners 22. Specifically, one end of the connecting rod 23 is fixed inside one runner 22, and the other end of the connecting rod 23 is fixed inside the other runner 22; one clamping body 31 is arranged on one connecting rod 23. The control device is configured to control the rotating shaft 21 to rotate 360°, so that the two runners 22 rotate 360°, and the M clamping bodies 31 arranged on the connecting rods 23 will also rotate 360°.
[0151] This embodiment also includes the following specific embodiments. When M is 3, the angle between the connecting lines of two adjacent connecting rods 23 and the rotating shaft 21 is 120° respectively; whenever the rotating device 20 rotates 120°, the clamping body 31 moves from one working position to the next working position. When M is 4, the angle between the connecting lines of two adjacent connecting rods 23 and the rotating shaft 21 is 90° respectively; whenever the rotating device 20 rotates 90°, the clamping body 31 moves from one working position to the next working position. When M is 5, the angle between the connecting lines of two adjacent connecting rods 23 and the rotating shaft 21 is 72° respectively; whenever the rotating device 20 rotates 72°, the clamping body 31 moves from one working position to the next working position. When M is 6, the angle between the connecting lines of two adjacent connecting rods 23 and the rotating shaft 21 is 60° respectively; whenever the rotating device 20 rotates 60°, the clamping body 31 moves from one working position to the next working position.
[0152] In the above embodiment when M is 4, the rotating device 20 has 4 working positions during rotation, which can be respectively set as: clamping position, identification position, testing position and releasing position. In the above embodiment when M is 5, the rotating device 20 has 5 working positions during rotation, which can be respectively set as: clamping position, identification position, first testing position, second testing position and releasing position. In the above embodiment when M is 6, the rotating device 20 has 6 working positions during rotation, which can be respectively set as: clamping position, identification position, first testing position, second testing position, determination position and releasing position. In the above specific embodiments when M = 5 or 6, the first testing position and the second testing position are respectively used to test the performance of the pump source module 42, and the control device obtains the test results at the two testing positions and analyzes them to finally determine the performance parameters of the pump source module 42. In the above specific embodiment when M = 6, if the test results at the two testing positions are different, the pump source module 42 will enter the determination position for a new determination operation. The specific determination operation may include testing other parameters to indirectly feedback whether the test results at the two testing positions are credible. Or, if the test results at the two testing positions are the same but both do not meet the preset performance of the pump source module 42, it will enter the determination position again to determine whether the pump source module 42 is damaged.
[0153] In addition, in the above embodiment when M is 6, the rotating device 20 has 6 working positions during rotation, which can be respectively set as: clamping position, identification position, first testing position, second testing position, third testing position and releasing position. When three testing positions are set, three sets of detection devices 50 need to be set correspondingly to realize the testing of different testing positions.

In another specific embodiment, the first connecting member 311 is movably connected to the connecting rod 23. The first connecting member 311 can be set to be connected by an oil-free bushing or a self-lubricating bearing. The first connecting member 311 and the connecting rod 23 are in a semi-fixed connection state, and the clamping body 31 can perform damped shaking relative to the connecting rod 23, facilitating that when rotating, the clamping body 31 is under the action of gravity below the connecting rod 23, and the movement range of the clamping body 31 is small and relatively controllable.
[0157] 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 driving member 315a is movably disposed at the first opening 31a. The positioning member body 315b is respectively disposed 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.
[0162] The driving member 315a drives the positioning member body 315b to move in the Y-axis direction so that the positioning pin 315c passes through the first through hole and exposes 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 in parallel, and the Y-axis direction is perpendicular to the extending direction of the side surface of the first clamping plate 312. In this embodiment, the specific structure of the moving clamping mechanism 315 is refined, and the driving member 315a drives the positioning member body 315b and the positioning pin 315c to move into the clamping space in the Y-axis direction to realize the function of clamping the device under test 40.
[0163] In one embodiment, please refer to Figure 9 and Figure 10 , the driving member 315a is a driving cylinder. The moving clamping mechanism 315 further includes: a driving auxiliary member 3150. The driving auxiliary member 3150 includes: a gas source 3151, M solenoid valves 3152, a gas-electricity integrated slip ring 3153, and a gas pipeline 3154.
[0164] The gas source 3151 is used to provide driving gas, and its installation position is not specifically limited, as long as it does not prevent the rotating device 20 from driving the clamping device 30 to move.
[0165] The solenoid valve 3152 is connected to the gas source 3151 through a pipeline and is used to control the flow rate, on-off, and flow direction of the gas in the pipeline. The solenoid valve 3152 has bidirectionality, that is, it can be opened and closed bidirectionally. When in the embodiment as Figure 1 shown, when M = 4, 4 solenoid valves 3152 are provided.
[0166] The pneumatic and electrical integrated slip ring 3153 is arranged at one end of the rotating shaft 21. The pneumatic and electrical 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 air ports. Relative to the fixed shaft 3153a, the moving shaft 3153b is arranged inside the rotating shaft 21. Relative to the moving shaft 3153b, the fixed shaft 3153a is arranged outside the rotating shaft 21. The moving shaft 3153b can rotate with the rotation of the rotating shaft 21. As Figure 9 and Figure 10 shown, both the moving shaft 3153b and the fixed shaft 3153a of the pneumatic and electrical integrated slip ring 3153 have 4 groups of air ports, and these 4 groups of air ports are arranged between the moving shaft and the fixed shaft to allow gas to pass through.
[0167] The gas pipelines 3154 are respectively connected to the gas source 3151 and the solenoid valve 3152, the solenoid valve 3152 and the air port on the fixed shaft 3153a, and the air port on the moving shaft 3153b and the driving cylinder. The gas pipelines 3154 can be tied to structures such as the runner 22 or the connecting rod 23 through straps.
[0168] As Figure 9 shown is the schematic diagram of the driving cylinder (driving part 315a) arranged on two clamping plates of the same clamping body 31 driving the positioning part body 315b and the positioning pin 315c to clamp the device under test 40. Figure 9 In it, the gas in the gas source 3151 enters the gas pipeline 3154. When the first solenoid valve is opened in the first direction, it enters from the a1 port of the fixed shaft, the gas passes through the moving shaft 3153b, and flows out from the b1 port of the moving shaft 3153b. After flowing through the driving part 315a in the two clamping plates (the first clamping plate 312 and the second clamping plate 313), it enters from the b5 port again, the gas 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 part 315a drives the positioning part body 315b and the positioning pin 315c to clamp the device under test 40.
[0169] The first solenoid valve, as Figure 10 shown, is the schematic diagram of the driving cylinder (driving part 315a) arranged on two clamping plates of the same clamping body 31 driving the positioning part body 315b and the positioning pin 315c to release the device under test 40. Figure 10 In it, the gas in the gas source 3151 enters the gas pipeline 3154. When the first solenoid valve is opened in the second direction, it enters from the a5 port of the fixed shaft 3153a, the gas passes through the moving shaft 3153b, and flows out from the b5 port of the moving shaft 3153b. After flowing through the driving part 315a in the two clamping plates, it enters from the b1 port again, the gas 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 part 315a drives the positioning part body 315b and the positioning pin 315c to release the device under test 40.
[0170] In this embodiment, a driving auxiliary member 3150 is adopted to assist in driving the positioning member body 315b and the positioning pin 315c to clamp and release the device under test 40. On the one hand, the operating principle of the driving auxiliary member 3150 is simple, and the directionality of the gas flow allowed by the solenoid valve 3152 is controllable; on the other hand, the pneumatic and electrical integrated slip ring 3153 can effectively control the installation 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.
[0171] In one embodiment, the clamping and power supply assembly 32 is movably arranged on the first support body 11. When the clamping body 31 clamps the device under test 40 and runs to the test station, the clamping and power supply assembly 32 clamps the device under test 40 and supplies power to 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 electrodes of the pump source module 42 in the Z-axis direction.
[0177] The fiber optic disc 402 protrudes 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 output hole of the pump source module 42, it is wound around the fiber optic disc 402 and then led out through the through hole 412a of the second side wall 412.

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.
[0179] In one embodiment, please refer to Figure 14 , the pump source module 42 includes: a pump unit 421, a TC cooling plate 422, and a heat dissipation fin 423.
[0180] The pump unit 421 includes one or more semiconductor laser chips. The pump unit 421 has positive and negative power connection pins. The TC cooling plate 422 is embedded in the bottom wall 401 and is in contact with the pump unit 421. The TC cooling plate 422 has positive and negative power connection pins. In the Z-axis direction, the pump unit 421 is disposed above the TC cooling plate 422.

[0181] In this embodiment, a heat dissipation structure is provided in the pump source module 42 to dissipate heat from the pump unit 421, which can reduce unnecessary damage to the pump unit 421 during the test.
[0182] In one embodiment, please refer to Figure 4 , the outer side of the connection of any two side walls of the test chamber 41 has an external chamfer. In a specific embodiment, the external chamfer can be set to 30° - 45°.

The second recognition device 53 is used to obtain the contour of the diaphragm retaining ring 51, and to obtain the light emitted from the pump source module 42 to be tested irradiating on the contour of the diaphragm retaining ring 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 diaphragm retaining ring 51 and the light emitted from the pump source module 42 to be tested irradiating on the contour of the diaphragm retaining ring 51, which is convenient for improving the accuracy of the performance detection of the pump source module 42.
[0190] In one embodiment, the detection device further includes: a temperature monitoring module 54. The temperature monitoring module 54 is arranged 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.

[0193] The feeding track 61 is arranged on the platform 10a and can be driven along the X-axis, and is used to convey the device 40 to be tested. The running speed of the feeding track 61 is adjusted by the control device.
[0194] The movement stop portion 62 is arranged at the end point of the feeding track 61 driven along the X-axis. The height of the movement stop portion 62 in the Z-axis direction is higher than the height of the feeding track 61 in the Z-axis direction. The proximity switch 63 is arranged on the movement stop portion 62 and is used to sense whether the device 40 to be tested approaches a preset feeding position. The feeding track drive shaft 66 is arranged below the movement stop portion 62 and is used to drive the feeding track 61 to move.
[0195] In this embodiment, an automated feeding device 60 is provided. On the one hand, the feeding 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 40 to be fed can be fed when it runs to the movement stop portion 62 during the transmission of the feeding track 61, and its feeding process can be seamlessly connected.
[0196] In one embodiment, please refer to Figure 20 , a contact member 31b is provided on the outer side wall of the first clamping plate 312 or the outer side wall of the second clamping plate 313. The feeding device 60 further includes: a photoelectric sensor 64, which is provided on the inner side 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 provided 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 member 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 member 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.
[0197] In one embodiment, when the photoelectric sensor 64 senses through the contact member 31b that a clamping body 31 runs to the feeding position, and the proximity switch 63 senses that the device under test 40 approaches the feeding position, the control device can send a feeding operation instruction, and the feeding operation instruction controls the two moving clamping mechanisms 315 to clamp the device under test 40 at the same time.
[0198] In this embodiment, the feeding operation is restricted by two operating conditions, and the condition for issuing the feeding operation instruction is more stringent, and the probability of misaligned clamping is lower. While realizing automatic feeding, the device under test 40 is protected to the greatest extent.
[0199] In one embodiment, the feeding device 60 further includes: a centering component 65, which is provided on both sides of the feeding track 61. The centering component 65 is in a converging shape, and the dimension closer to the movement stop portion 62 in the X-axis direction is smaller, and the minimum dimension is equal to the outer edge dimension of the device under test 40.
[0200] In this embodiment, the setting of the centering component 65 can automatically adjust the placement position of the device under test 40 on the feeding track 61, reducing the occurrence of misalignment of the clamping during feeding.

[0202] The supporting member 71 is rotatably and liftably provided on the platform 10a and is used to support the device under test 40 that has completed the test. The discharging track 72 is provided on the platform 10a and can be driven along the X-axis and is used to convey the device under test 40 that has completed the test.
[0203] In this embodiment, the supporting member 71 is located at the releasing station. When the clamping device 30 clamps the device that has completed the test and runs to the releasing station, the clamping device 30 releases the device under test 40 that has completed the test. The supporting member 71 supports the device under test 40 that has completed the test and rotates it to the side. At the same time, the clamping device 30 is driven by the rotating device 20 and rotates to the loading position. The supporting member 71 supports the device under test 40 that has completed the test to the unloading track 72 for unloading. In this embodiment, the supporting member 71 can be lifted and rotated, which is convenient for the unloading operation and does not affect the rotating device 20 to drive the clamping device 30 to rotate to the loading position, improving the operation efficiency of the system.
[0204] In one embodiment, please refer to Figure 21 , the unloading track 72 includes two tracks arranged at intervals, such as Figure 21 the first unloading track 72a and the second unloading track 72b shown in the figure. The interval between the two unloading tracks 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.
[0205] In this embodiment, the first unloading track 72a and the second unloading track 72b are provided, which is convenient for the supporting member 71 to place the device under test 40 that has completed the test, and at the same time can ensure that the device under test 40 that has completed the test will not have accidents (such as being bumped or overturned) during the unloading process.

The automated test method further includes: when the clamping device 30 on the rotating device 20 is at the identification station, the control device controls the first identification device 80 to identify the parameter information of the device under test 40 and save it to the control device.
[0212] In one embodiment, the automated test system further includes a loading device 60. The loading device 60 includes: a loading track 61, a movement stop portion 62, and a proximity switch 63. The automated test method further includes: when the clamping device 30 runs to the loading position and the proximity switch 63 senses that the device under test 40 is approaching the loading position, the control device controls the clamping device 30 to clamp the device under test 40.
[0213] In one embodiment, the automated test system further includes an unloading device 70. The unloading device 70 includes: a support member 71 and an unloading track 72. The automated test method further includes: the control device controls the support member 71 to be located at the unloading position. When the clamping device 30 clamps the device that has completed the test and runs to the unloading position, the control device controls the clamping device 30 to release the device that has completed the test. The control device controls the support member 71 to support the device under test 40 that has completed the test and rotate it to the side. 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 under test 40.
[0214] As Figure 1 shown in the embodiment, the automated test system 100 further includes: a first identification device 80. The clamping device 30 includes: a clamping power-on component 32 and four clamping bodies 31. The rotating device 20 has four stations during rotation, which are, in order counterclockwise, a clamping station, an identification station, a test station, and a release station.
[0215] The four clamping bodies 31 are respectively arranged on the rotating device 20, and when one of the clamping bodies 31 is at the clamping station, the other three clamping bodies 31 are respectively at the identification station, the test station, and the release station.
[0216] The control device is configured to: when the clamping body 31 is at the clamping station, control the clamping body 31 to clamp the device under test 40; when the clamping body 31 is at the identification station, control the first identification device 80 to identify the parameter information of the device under test 40; when the clamping body 31 is at the test station, control the clamping power-on component 32 to power on the device under test 40; when the clamping body 31 is at the release station, control the clamping body 31 to release the device under test 40.
[0217] As Figure 18 、 Figure 19 、 Figure 20As shown, the rotation device 20 pauses at the clamping station for 1 to 2 seconds to load the device under test 40 onto the clamping body 31. The device under test 40 houses the pump source module 42 to be tested. During the loading process, the position of the device under test 40 is confirmed by a proximity switch 63 as shown in Figure 19 , and the position of the clamping body 31 is confirmed by a photoelectric sensor 64 as shown in Figure 20 . When both the device under test 40 and the clamping body 31 are in place, the two movable clamping mechanisms 315 clamp simultaneously to complete the loading operation.
[0218] The rotation device 20 rotates counterclockwise by 90°. The clamping body 31 that has completed loading pauses at the identification station for 1 to 2 seconds to identify the product information (such as product model, product identification code, etc.) of the pump source module 42 to be tested in the device under test 40. As shown in Figure 11 , the side wall of the test chamber 41 fixedly provided with the pump source module 42 has an observation window 413a. The product information of the pump source module 42 can be set as a two-dimensional code and is exposed at the observation window 413a. At the identification station, a first identification device 80 as shown in Figure 18 takes a photo of the observation window 413a and transmits the photo result to the control device. The control device analyzes the two-dimensional code information to obtain the product information of the pump source module 42. The control device can also call the corresponding test program according to the product information of the pump source module 42.
[0219] The rotation device 20 rotates counterclockwise by 90°. The pump source module to be tested for which the product information has been identified moves to the test station. The clamping body 31 pauses at the test station for about 1 to 2 minutes to complete the performance test of the pump source module 42. When the clamping body 31 clamps the device under test 40 and reaches the test station, a clamping power supply assembly 32 as shown in Figure 4 supplies power to the pump source module 42. Specifically, the power supply body 321 moves in the negative Y-axis direction ( Figure 4 the direction indicated by the arrow is the positive direction) until it stops moving when the chamfer structure inside the accommodating portion 321a matches the chamfer structure outside the test chamber 41. At this time, the first power supply contact 322 is electrically connected to the TC refrigeration plate 422; the second power supply contact 323 is electrically connected to the pump unit 421; the control device controls the clamping power supply assembly 32 to supply power to the pump unit 421. The control device controls the detection device 50 to open to detect parameters such as the NA value of the pump source module 42, the divergence angle of the emitted 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 control device controls the power supply body 321 to move in the positive Y-axis direction until the clamping power supply assembly 32 moves away from the clamping body 31 as a whole (without affecting the rotation action of the rotation device 20, that is, the clamping power supply assembly 32 will not touch the clamping body 31 or the device under test 40).
[0220] The rotating device 20 rotates counterclockwise by 90°, and the pump source module 42 that has completed the test moves to the release station, where it pauses for about 1 to 2 seconds. As Figure 21 shown, the support member 71 in the blanking device 70 supports the device under test 40 that has completed the test, and the clamping body 31 releases the device under test 40 that has completed the test. The control device controls the support member 71 to support the device under test 40 that has completed the test and then lower it by a certain distance, and then rotates the support member 71 to a position where it will not touch the rotating device 20; the control device controls the support member 71 to rise to a position higher than the blanking track 72, and the control device further controls the support member 71 to rotate to a position corresponding to the gap formed by the first blanking track 72a and the second blanking track 72b; the control device further controls the support member 71 to lower until the device under test 40 that has completed the test is placed on the blanking track 72 to complete the blanking operation.
