DETAILED DESCRIPTION

[0030] The present application will be described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that the embodiments described below or the technical features between the embodiments can be combined arbitrarily to form new embodiments without conflict.

[0032] like Figures 1 to 5 As shown in the figure, this application discloses an automatic testing system 10. The automatic testing system 10 includes a machine base 100, on which a loading device 200, a feeding device 300, and a testing device 400 are provided. The loading device 200 is used to store multiple test hard disks 600, and the feeding device 300 is used to transport the multiple test hard disks 600 on the loading device 200 to the testing device 400. The testing device 400 includes a first testing component 410 and a second testing component 420. The first testing component 410 is used to place the multiple test hard disks 600, and the second testing component 420 is movable relative to the first testing component 410. When the multiple test hard disks 600 are placed on the first testing component 410, the second testing component 420 moves relative to the first testing component 410 to a first position. The first testing component 410 and the second testing component 420 clamp the pins of the multiple test hard disks 600 and test the multiple test hard disks 600.

[0033] This application improves upon the traditional automatic testing system 10 by using a loading device 200 to store multiple test hard drives 600 to be tested, and then using a feeding device 300 to continuously transport the multiple test hard drives 600 from the loading device 200 to the testing device 400. This allows the testing device 400 to continuously test the multiple test hard drives 600, thereby ensuring uninterrupted and smooth testing and improving testing efficiency to a certain extent. When the multiple test hard drives 600 are transported to the testing device 400, they are placed on the first testing component 410, and the second testing component 420 moves to the first testing component 410. The positioning allows the second test component 420 and the first test component 410 to simultaneously clamp the pins on both sides of multiple test hard drives 600, and to perform parallel testing on multiple test hard drives 600 at once. The testing method of clamping the pins of the test hard drives 600 by the first test component 410 and the second test component 420 replaces the traditional method of plugging and unplugging each test hard drive 600, which significantly shortens the overall testing time and reduces the number of operations of plugging and unplugging hard drives by robotic arms or manual plugging and unplugging and unplugging tests. This improves the problem of low testing efficiency caused by hard drive plugging and unplugging tests and increases testing efficiency.

[0034] It should be noted that the first position in this application can be understood as the position of the second test component 420 when the second test component 420 is moved above the initial position and pressed onto the pins of the multiple test hard disks 600.

[0035] Further, the testing device 400 further comprises a testing frame 430, the second testing assembly 420 is movably connected with the testing frame 430 and is movable relative to the testing frame 430, when the plurality of testing hard disks 600 are placed on the first testing assembly 410, the first testing assembly 410 aligns the pins of the plurality of testing hard disks 600 in the same direction; the second testing assembly 420 is moved to the first position relative to the first testing assembly 410 to be pressed on the pins of the plurality of testing hard disks 600.

[0036] In the embodiment, the second testing assembly 420 is movably connected with the testing frame 430, wherein the second testing assembly 420 can be moved relative to the testing frame 430 by the driving of the motor; when the plurality of testing hard disks 600 are placed on the first testing assembly 410, the first testing assembly 410 aligns the pins of the plurality of testing hard disks 600 in the same direction, so that the second testing assembly 420 can be pressed on the pins of the plurality of testing hard disks 600 at the same time when it is moved to the first position, so that the situation that the pins of one or more testing hard disks 600 are not contacted or separated is not easy to occur, and the stability and accuracy of the clamping test of the pins of the plurality of testing hard disks 600 by the second testing assembly 420 and the first testing assembly 410 are ensured.

[0037] Specifically, the first testing assembly 410 comprises a first testing plate 411, a plurality of hard disk testing positions 412 are arranged on the first testing plate 411 at intervals, and the plurality of hard disk testing positions 412 are arranged along the length direction of the first testing plate 411; a first testing pin group 413 is arranged in each hard disk testing position 412, and the plurality of first testing pin groups 413 are arranged in the same direction; the second testing assembly 420 comprises a second testing plate 421, and a plurality of second testing pin groups 422 are arranged on the second testing plate 421, each second testing pin group 422 corresponds to the position of each first testing pin group 413 one by one; when the plurality of testing hard disks 600 are placed in each hard disk testing position 412 respectively, each first testing pin group 413 is in contact with the pins on one side of each testing hard disk 600 respectively; the second testing plate 421 is moved to the first position relative to the first testing plate 411 and is pressed above the plurality of testing hard disks 600, each second testing pin group 422 is in contact with the pins on the other side of each testing hard disk 600 respectively; when the testing hard disk 600 completes the test, the second testing plate 421 is moved to the second position relative to the first testing plate 411 to release the plurality of testing hard disks 600.

[0038] In the embodiments of the present application, the plurality of hard disk test positions 412 are arranged on the first test plate 411, so that each test hard disk 600 can be placed in the hard disk test position 412 for testing. Since the first test pin group 413 is arranged in each hard disk test position 412, when the test hard disk 600 is placed in the test hard disk 600 position, the pin on the side of the test hard disk 600 close to the first test pin group 413 will be in contact with the first test pin group 413. The second test pin group 422 is arranged on the second test plate 421 corresponding to the position of each first test pin group 413. When the test hard disk 600 needs to be tested, the second test plate 421 is moved to the first position relative to the test frame 430, and the second test pin group 422 on the second test plate 421 is in contact with the pin on the side of the test hard disk 600 away from the first test pin group 413. At this time, the first test plate 411 and the second test plate 421 are in a state of clamping the pins of the test hard disk 600, which is similar to the state of inserting the test hard disk 600 into the test interface. That is, the first test plate 411 and the second test plate 421 form a structure similar to the test interface after clamping and cooperating, so as to replace the traditional test interface, so that the test hard disk 600 is tested under the clamping and cooperation of the first test plate 411 and the second test plate 421.

[0039] When the plurality of test hard disks 600 are tested, the second test plate 421 is moved away from above the plurality of test hard disks 600 and away from the plurality of test hard disks 600, so that the second test plate 421 does not block the plurality of test hard disks 600, and the plurality of test hard disks 600 are exposed to the environment again, which facilitates the use of a mechanical arm to grab and directly grab the plurality of test hard disks 600 from the first test plate 411.

[0040] The above method replaces the traditional test process of plugging and unplugging each test hard disk 600 for testing, greatly shortens the overall test time, reduces the number of mechanical arm plugging and unplugging hard disks or manual plugging and unplugging test operations, and improves the problem of low test efficiency caused by plugging and unplugging hard disks for testing, thereby improving the test efficiency.

[0042] Before starting the test, a plurality of test hard disks 600 can be placed on the hard disk carrying plate 250, and then a plurality of hard disk carrying plates 250 are stacked in the feeding position 212, so that the feeding position 212 can accommodate a plurality of test hard disks 600 at the same time, and the automatic test system 10 can test more test hard disks 600 at a time.

[0043] When starting the test, the transplanting disc 241 below the feeding position 212 sends the hard disk carrying plate 250 at the lowermost position into the transplanting track 242, wherein a conveyor belt can be installed in the transplanting track 242, and the hard disk carrying plate 250 is conveyed to the feeding position 213 by the conveyor belt, so that the feeding device 300 sends the test hard disk 600 on the hard disk carrying plate 250 to the test device 400 for testing, and when a plurality of test hard disks 600 on one hard disk carrying plate 250 are sent to the test device 400, the next hard disk carrying plate 250 loaded with test hard disks 600 is sent to the transplanting track 242 by the transplanting disc 241, and the above operation is repeated, so that the rapid feeding of a plurality of test hard disks 600 is realized, and the feeding efficiency of the automatic test system 10 is improved.

[0050] In the embodiment of the present application, the gantry frame 310 is installed on the machine table 100, so that the gantry frame 310 can serve as a support structure for the plurality of mechanical arms. When the plurality of mechanical arms are installed on the gantry frame 310 and run, the stability of the plurality of mechanical arms in operation can be effectively ensured. The feeding mechanical arm 320 is arranged close to the feeding device 200, the testing mechanical arm 340 is arranged close to the testing device 400, and the discharging mechanical arm 330 is arranged close to the discharging device 500. In this way, corresponding mechanical arms can be used to grab or place the test hard disks 600 at different stages of testing, so as to avoid the increase of testing time caused by the long movement path of the plurality of mechanical arms, thereby reducing the testing efficiency.

[0051] The feeding device 200, the testing device 400 and the discharging device 500 can be arranged in a straight line, so that the transplanting track 242 is arranged in a straight line close to the feeding device 200, the testing device 400 and the discharging device 500.

[0055] Figure 6 FIG. 1 shows a schematic diagram of the first test plate in the second embodiment of the automatic test system of the application. Figure 6 The automatic test system 10 further comprises a control module 110, and the test rack 430 is further provided with a first optical detection device 440, which is in communication connection with the control module 110. The first optical detection device 440 is used to detect whether the plurality of test hard disks 600 placed on the first test plate 411 are aligned in the same direction. If aligned, the first optical detection device 440 transmits a detection signal to the control module 110, and the control module 110 controls the second test plate 421 to move to the first position relative to the first test plate 411. If not aligned, the first optical detection device 440 transmits a detection signal to the control module 110, and the control module 110 controls the second test plate 421 to remain in the initial position.

[0056] The difference between the embodiment and the previous embodiment is that the first optical detection device 440 is further arranged on the test rack 430 in the embodiment. The first optical detection device 440 can be a reflection optical fiber sensor. The emitter and the receiver of the reflection optical fiber sensor are respectively installed on the two sides of the test rack 430. The light beam emitted by the emitter is close to the end portion with the pin of the plurality of test hard disks 600 on the first test plate 411. When one or more test hard disks 600 block or interrupt the light beam between the emitter and the receiver, the receiver detects the weakening or disappearance of the light signal and triggers the corresponding switch signal, so as to determine whether the positions of the plurality of test hard disks 600 are aligned in the same direction.

[0057] In the actual operation process, when the plurality of test hard disks 600 are placed on the first test plate 411, if the light beam emitted by the emitter of the reflection optical fiber sensor can be normally received by the receiver, it indicates that the plurality of test hard disks 600 are in the aligned state at the first test plate 411. At this time, the reflection optical fiber sensor transmits a detection signal to the control module 110, and the control module 110 controls the second test plate 421 to move to the first position relative to the first test plate 411, so that the second test plate 421 and the first test plate 411 clamp and test the plurality of test hard disks 600.

[0058] If the light beam emitted by the emitter of the counter light fiber sensor cannot be received by the receiver, it indicates that the plurality of test hard disks 600 on the first test plate 411 are in a misaligned state. At this time, the counter light fiber sensor transmits a detection signal to the control module 110, and the control module 110 controls the second test plate 421 to remain stationary at the initial position, which facilitates the operator to timely adjust the position of the plurality of test hard disks 600 on the first test plate 411, so that the plurality of test hard disks 600 are aligned in the same direction on the first test plate 411, and then subsequent testing is performed. In this way, it can be ensured that after the second test plate 421 moves to the first position, it can be correctly pressed on the pins of the plurality of test hard disks 600, avoiding the occurrence of virtual connection or disconnection of the test pins due to the deviation of the position of the test hard disks 600, and ensuring the accuracy and stability of the simultaneous testing of the first test plate 411 and the second test plate 421 on the plurality of test hard disks 600.

[0059] When the plurality of test hard disks 600 are placed on the feeding transfer 350 or the discharging transfer 360, due to mechanical vibration and other reasons, the positions of the plurality of test hard disks 600 on the feeding transfer 350 or the discharging transfer 360 may be misaligned. In order to ensure the stability and accuracy of the mechanical arm in grabbing the test hard disks 600 on the feeding transfer 350 or the discharging transfer 360, the feeding transfer 350 and the discharging transfer 360 are also improved in the present application, and the specific improvements are as follows:

[0060] Figure 7 Fig. 4 is a schematic view of the feeding transfer and the discharging transfer installed on the feeding track in the third embodiment of the automatic test system of the present application, Figure 8 Fig. 5 is a schematic view of the transfer plate in the third embodiment of the automatic test system of the present application, as shown in Figure 7 and Figure 8 The feeding transfer 350 and the discharging transfer 360 each include a transfer plate 351, and the transfer plate 351 is provided with a plurality of placement positions 352 at intervals, and each placement position 352 is used to accommodate a test hard disk 600. The end of each placement position 352 is provided with a positioning member 353, and the positioning member 353 is signal connected with the control module 110. When the test hard disk 600 is placed on the placement position 352, the control module 110 controls the positioning member 353 to abut against the test hard disk 600 from one end of the test hard disk 600, so that the plurality of test hard disks 600 are aligned in the same direction on the transfer plate 351.

[0061] In the embodiment, multiple placement positions 352 are arranged on the transplanting plates 351 of the feeding transplanting 350 and the discharging transplanting 360, so that each test hard disk 600 can be placed in a designated position, and the placement positions 352 provide accommodation spaces for the test hard disks 600, so that the test hard disks 600 can be limited in the accommodation spaces formed by the placement positions 352 when placed in the corresponding placement positions 352, so that the test hard disks 600 form the first positioning in the placement positions 352, so that the test hard disks 600 do not shake or misalign obviously.

[0062] In addition, in the embodiment, a positioning member 353 is arranged in each placement position 352, and the control module 110 controls the positioning member 353 to abut or release the test hard disk 600 placed in the placement position 352, so as to align or release the test hard disks 600 in the multiple placement positions 352.

[0063] In actual operation, when the multiple test hard disks 600 are placed in the corresponding placement positions 352 on the transplanting plates 351, the control module 110 controls the positioning member 353 to abut one end of the test hard disk 600 in the placement position 352, so that the position of the test hard disk 600 placed in the placement position 352 is moved to a preset position under the pushing of the positioning member 353, so that the multiple test hard disks 600 can be moved to the preset position in the placement position 352 under the pushing of the corresponding positioning member 353, to realize the second positioning of the test hard disk 600 on the transplanting plate 351, so that the multiple test hard disks 600 are aligned in the same direction on the transplanting plate 351, thereby ensuring the stability and accuracy of the mechanical arm in grabbing the test hard disk 600 in the feeding transplanting 350 or the discharging transplanting 360.

[0064] When the test hard disk 600 on the transplanting plate 351 needs to be grabbed by the mechanical arm, the control module 110 controls the positioning member 353 to release or move away from the test hard disk 600, so that the test hard disk 600 is no longer constrained and contacted by the positioning member 353, so that the mechanical arm can easily grab the test hard disk 600, so that the test hard disk 600 is not easy to collide with the positioning member 353, which is beneficial to prolong the service life of the test hard disk 600, and ensures the stability and smoothness of the test process.

[0065] It should be noted that, in order to realize that the control module 110 controls the abutting or loosening of the positioning piece 353 to the test hard disk 600 placed in the placement position 352, in the embodiment, a sliding groove can be opened in the placement position 352 close to the end position of the test hard disk 600, the extension direction of the sliding groove can be the same as the length direction of the test hard disk 600, and the positioning piece 353 is arranged in the sliding groove. At this time, the positioning piece 353 can be a sliding block, the motor is connected with the sliding block, the control module 110 is signal connected with the motor, so that the control module 110 can control the motor to drive the sliding block to move in the extension direction of the sliding groove. When the sliding block moves close to one end of the test hard disk 600, the sliding block can abut to one end of the test hard disk 600, so that the test hard disk 600 is pushed to the preset position from the initial position placed in the placement position 352. When the test hard disk 600 needs to be grabbed, the control module 110 can control the motor to drive the sliding block to move away from the test hard disk 600, so that the sliding block is not in contact with the test hard disk 600, and the collision between the test hard disk 600 and the sliding block in the grabbing process of the mechanical arm is prevented. That is, in the embodiment, the control module 110 controls the positioning or loosening of the test hard disk 600 by the positioning piece 353, which is a conventional technology. In order to facilitate understanding, only the mode that the control module 110 controls the motor to drive the sliding block to move in the sliding groove is taken as an example to illustrate the control of the control module 110 to the positioning piece 353, and does not limit the specific implementation mode. Other modes that can realize automatic positioning are also available.

[0066] Figure 9 The fourth embodiment of the automatic test system of the present application is a schematic view of a transplanting plate, as shown in Figure 9 The second optical detection device 380 is also arranged on the transplanting plate 351, and the second optical detection device 380 is in communication connection with the control module 110. The second optical detection device 380 is used to detect whether the plurality of test hard disks 600 on the transplanting plate 351 are aligned in the same direction. If they are aligned, the second optical detection device 380 transmits a detection signal to the control module 110, and the control module 110 controls the transplanting plate 351 to move to the position corresponding to the test device 400 of the transplanting track 242, or controls the transplanting plate 351 to move to the position corresponding to the discharging device 500 of the transplanting track 242. If they are not aligned, the second optical detection device 380 transmits a detection signal to the control module 110, and the control module 110 controls the transplanting plate 351 to remain in the initial position.

[0067] The difference between this embodiment and the previous embodiment is that in this embodiment, the second optical detection device 380 is arranged on the transplanting plate 351 of the feeding transplanting 350 and the discharging transplanting 360. The second optical detection device 380 can be a retro-reflective fiber sensor. The transmitter and the receiver of the retro-reflective fiber sensor are respectively arranged on the two sides of the transplanting plate 351. The light beam emitted by the transmitter is close to the end of the plurality of test hard disks 600 on the transplanting plate 351. When one or more test hard disks 600 block or interrupt the light beam between the transmitter and the receiver, the receiver detects the weakening or disappearance of the light signal, and triggers the corresponding switch signal.

[0068] In actual operation, after the plurality of test hard disks 600 are placed on the transplanting plate 351, if the light beam emitted by the transmitter of the retro-reflective fiber sensor can be normally received by the receiver, it indicates that the plurality of test hard disks 600 are in an aligned state on the transplanting plate 351. At this time, when the transplanting plate 351 is the transplanting plate 351 on the feeding transplanting 350, the retro-reflective fiber sensor transmits the detection signal to the control module 110, and the control module 110 controls the feeding transplanting 350 to move to the position of the test device 400 corresponding to the transplanting track 242, so that the test mechanical arm 340 can conveniently grab the test hard disk 600 from the feeding transplanting 350 to the test device 400 for testing.

[0069] When the transplanting plate 351 is the transplanting plate 351 on the discharging transplanting 360, the retro-reflective fiber sensor transmits the detection signal to the control module 110, and the control module 110 controls the discharging transplanting 360 to move to the position of the discharging device 500 corresponding to the transplanting track 242, so that the discharging mechanical arm 330 can conveniently grab the test hard disk 600 which has completed the test from the discharging transplanting 360 to the discharging device 500.

[0070] If the light beam emitted by the transmitter of the retro-reflective fiber sensor cannot be received by the receiver, it indicates that the plurality of test hard disks 600 are in a misaligned state on the transplanting plate 351. At this time, the retro-reflective fiber sensor transmits the detection signal to the control module 110, and the control module 110 controls the transplanting plate 351 to remain in the initial position, so that the operator can timely adjust the position of the plurality of test hard disks 600 on the transplanting plate 351, so that the plurality of test hard disks 600 are aligned in the same direction on the transplanting plate 351, and then the subsequent transfer is performed, which is beneficial to improve the stability and accuracy of the test process.

[0072] In the embodiment, when the test device 400 tests the plurality of test hard disks 600, the plurality of test hard disks 600 in the first test state or the second test state are tested, and the test signal is transmitted to the computer 700, wherein the first test state can be a state that the test hard disk 600 is a good product, and the second test state can be a state that the test hard disk 600 is a defective product.

[0073] After the computer 700 obtains the detection signal of the test device 400, the plurality of test hard disks 600 are marked, for example, the test hard disk 600 detected as the first test state and the test hard disk 600 detected as the second test state are respectively marked in a coded manner.

[0074] After the test device 400 completes the test on the plurality of test hard disks 600, the computer 700 transmits the computer 700 signal to the control module 110, and the control module 110 controls the test mechanical arm 340 to respectively grab the test hard disk 600 marked as the first test state and the test hard disk 600 marked as the second test state on the test device 400 to different sides of the unloading transplanting 360 according to the computer 700 signal obtained, so as to realize the classification and placement of the test hard disks 600 in different test states.

[0075] When the unloading moving and transplanting track 360 moves to the position corresponding to the position of the unloading device 500, the unloading mechanical arm 330, according to the computer 700 signal obtained, respectively grasps the test hard disk 600 marked as the first test state and the test hard disk 600 marked as the second test state on the unloading moving and transplanting track 360 to the first unloading position 520 and the second unloading position 530, so that the first unloading position 520 and the second unloading position 530 can respectively store the test hard disks 600 of the good products and the defective products, which effectively saves the time of the test personnel sorting the test hard disks 600 of the good products or the defective products, and is beneficial to improve the test efficiency.
