[0060] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0061] It should be noted that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely for ease of description and simplification of the present application. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present application. The terms "mounted," "connected," and "connected" should be interpreted broadly, and may include, for example, fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. The terms "parallel," "perpendicular," and "equal" encompass the described conditions and conditions similar to the described conditions, provided that the range of the similar conditions is within an acceptable range of deviation, as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes both absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5°; "perpendicular" includes both absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5°. "Equal" includes both absolute equality and approximate equality, where the acceptable deviation range for approximate equality may be, for example, that the difference between the two is less than or equal to 5% of either. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0062] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0063] As a storage device, hard drives undergo multiple tests before leaving the factory, including read and write tests, data consistency tests, performance tests, durability tests, continuous write tests, and burn-in tests. Read and write tests verify the read and write functionality of the hard drive. Data consistency tests verify the integrity and consistency of read and write data by writing and reading data. Performance tests measure the read and write speed of the hard drive for consecutive data blocks. Durability tests assess the performance changes and reliability of the hard drive over long-term use. Continuous write tests assess the durability of the hard drive by writing data over a long period of time. Burn-in tests simulate long-term use environments to assess the degree of hard drive degradation. These hard drive tests can screen out substandard products to ensure that the performance of shipped products meets requirements.

[0064] Various tests on hard drives can be performed by placing the hard drives in a test cabinet.

[0065] Currently, the hard disk trays are often transported to the test cabinet manually, and then the hard disks are manually removed from the trays and placed into the test cabinet for testing. In the related art, hard disk testing consumes a lot of manpower and is inefficient.

[0066] Based on this, an embodiment of the present application provides a hard disk detection device that can realize automatic detection of hard disks.

[0067] For example, the hard disk to be tested can be a mechanical hard disk or a solid state drive (SSD). In other words, the hard disk testing device can be a device for testing a mechanical hard disk or a device for testing a solid state drive.

[0068] Figure 1 A schematic diagram of a hard disk detection device provided in an embodiment of the present application. In the diagram, the positive x-direction is the front, the negative x-direction is the back, the positive y-direction is the right, the negative y-direction is the left, the positive z-direction is the top, and the negative z-direction is the bottom.

[0069] like Figure 1 As shown, the hard disk detection device includes a first hard disk pick-up and placement module M2 and a hard disk detection module M1. The first hard disk pick-up and placement module M2 is used to send the picked hard disk to the hard disk detection module M1, and the hard disk detection module M1 is used to detect the hard disk.

[0070] Specifically, the hard drive inspection equipment includes a first material bin A1 and a first empty disk bin A3. The first material bin A1 is used to store first trays T1 loaded with hard drives, while the first empty disk bin A3 is used to store empty first trays T1. A first hard drive retrieval module M2 is used to remove first trays T1 loaded with hard drives from the first material bin A1 and remove hard drives from first trays T1 loaded with hard drives. The first hard drive retrieval module M2 is also used to deliver hard drives removed from first tray T1 to the hard drive inspection module M1 and, after the hard drives on first tray T1 have been removed, deliver the empty first tray T1 to the first empty disk bin A3.

[0071] In this way, it is convenient to automatically remove the hard disk from the first tray T1 loaded with hard disks, send the removed hard disk to the hard disk detection module M1 for detection, and recycle the empty first tray T1 after the hard disk on the first tray T1 is removed, which is beneficial to reduce the labor and time consumed by the detection personnel and improve the detection efficiency.

[0072] In some possible implementations, the hard disk detection device further includes a second hard disk fetching and placing module M3 , which is configured to fetch the hard disk from the hard disk detection module M1 and send the hard disk to a completion position.

[0073] In this way, after the hard disk is tested, the tested hard disk can be automatically sent to the completion location for storage, so that the testers do not need to wait for a long time during the hard disk testing process, which helps to reduce the labor and time consumed by the testers and improve the testing efficiency.

[0074] Specifically, the hard drive testing equipment also includes a second material bin A4 and a second empty disk bin A6. The second empty disk bin A6 is used to store empty second trays T2, while the second material bin A4 is used to store second trays T2 loaded with tested hard drives. A second hard drive retrieval module M3 is used to remove empty second trays T2 from the second empty disk bin A6 and load hard drives removed from the hard drive testing module M1 into the second tray T2. The second hard drive retrieval module M3 is also used to transport the loaded second trays T2 to the second material bin A4 after the hard drives have been loaded into the second trays.

[0075] In this way, the hard disks that have completed the inspection can be automatically loaded into the second tray T2 for storage.

[0076] Figure 2 A schematic diagram of a hard disk detection module provided in an embodiment of the present application.

[0077] like Figure 2 As shown, the hard disk detection module M1 includes a hard disk pushing mechanism 300 and a test cabinet 400 , and the hard disk pushing mechanism 300 and the test cabinet 400 are arranged front to back relative to each other.

[0078] The first hard disk pick-and-place module M2 is used to send the picked hard disk to the hard disk pushing mechanism 300. The hard disk pushing mechanism 300 is used to push the hard disk from the first hard disk pick-and-place module M2 into the test cabinet 400. The test cabinet 400 is used to test the hard disk.

[0079] In this way, it is convenient to automatically place the hard disk picked up by the first hard disk pick-and-place module M2 into the test cabinet 400 for testing, and it is relatively easy to automatically load the hard disk into the test cabinet 400 for testing.

[0080] In some examples where the hard disk detection device includes a second hard disk pick-and-place module M3, the second hard disk pick-and-place module M3 is used to remove the hard disk from the hard disk pushing mechanism 300 so that the hard disk that has completed detection can be automatically removed by the second hard disk pick-and-place module M3.

[0081] Exemplarily, the hard disk pushing mechanism 300 is also used to pull the hard disk out of the test cabinet 400 and into the hard disk pushing mechanism 300 .

[0082] In this way, after the hard disk inspection is completed, the hard disk that has completed the inspection can be returned to the hard disk pushing mechanism 300, and then the hard disk that has completed the inspection can be automatically taken away by the second hard disk pick-up and placement module M3, so that the inspection personnel do not need to wait for a long time during the hard disk inspection process, which is beneficial to reducing the labor and time consumed by the inspection personnel and improving the inspection efficiency.

[0083] Illustratively, the test cabinet 400 has a test cavity 410. Along the front-to-back direction, the side of the test cavity 410 facing the hard drive push mechanism 300 is open. The hard drive push mechanism 300 is used to push the hard drive from the first hard drive retrieval module M2 into the test cavity 410. After the test cabinet 400 completes the hard drive inspection, the hard drive push mechanism 300 is used to pull the hard drive out of the test cavity 410 and back into the hard drive push mechanism 300.

[0084] In some possible implementations, the test cabinet 400 has multiple layers of test cavities 410 arranged vertically. The hard drive inspection module M1 also includes a lifting mechanism 500, on which the test cabinet 400 is mounted. The lifting mechanism 500 is used to drive the test cabinet 400 upward and downward. The hard drive push mechanism 300 is used to push hard drives from the first hard drive retrieval module M2 into the test cavity 410 opposite the hard drive push mechanism 300.

[0085] In this way, through the cooperation of the lifting mechanism 500 and the hard disk pushing mechanism 300, the test cavities 410 of each layer of the test cabinet 400 can be opposite to the hard disk pushing mechanism 300 layer by layer, and the hard disks can be pushed into the test cavities 410 of the test cabinet 400 layer by layer. After the hard disks are tested, the hard disks can also be pulled out of the test cavities 410 of the test cabinet 400 layer by layer through the cooperation of the lifting mechanism 500 and the hard disk pushing mechanism 300, thereby facilitating the automated testing of large quantities of hard disks.

[0086] For example, each layer of the test cabinet 400 may have multiple test cavities 410 arranged in a left-right direction. When the hard drive pushing mechanism 300 is opposite to the test cavities 410 on a certain layer, the hard drive pushing mechanism 300 can simultaneously push multiple hard drives into the multiple test cavities 410 on that layer. The hard drive pushing mechanism 300 can also simultaneously pull the hard drives in the multiple test cavities 410 on that layer out to the hard drive pushing mechanism 300.

[0087] Figure 3 A schematic diagram of another hard disk detection module provided in an embodiment of the present application.

[0088] like Figure 3 As shown, in some possible implementations, the lifting mechanism 500 includes a frame assembly 510 , a cabinet drive assembly 520 , and a cabinet mounting assembly 530 .

[0089] The cabinet drive assembly 520 is arranged on the frame assembly 510, and the output end of the cabinet drive assembly 520 is transmission-connected to the cabinet installation assembly 530. The test cabinet 400 is fixedly connected to the cabinet installation assembly 530. The cabinet drive assembly 520 is used to drive the test cabinet 400 to rise and fall through the cabinet installation assembly 530.

[0090] In this way, the assembly of the test cabinet 400 and the lifting mechanism 500 is facilitated.

[0091] In some examples, the frame assembly 510 is provided with a guide assembly 540 , and the cabinet mounting assembly 530 is slidably connected to the frame assembly 510 via the guide assembly 540 . The guide assembly 540 is used to guide the cabinet mounting assembly 530 to slide up and down.

[0092] In this way, it is easy to achieve stable lifting and lowering of the test cabinet 400, and the test cabinet 400 is not prone to displacement during the lifting process, which facilitates the alignment of the test cavity 410 and the hard disk pushing mechanism 300, and thus helps the hard disk pushing mechanism 300 to efficiently and smoothly push the hard disk into the test cavity 410, and efficiently and smoothly pull the hard disk out of the test cavity 410.

[0093] For example, the guide assembly 540 can limit the horizontal movement and rotation of the frame assembly 510 .

[0094] Illustratively, the guide assembly 540 may include a plurality of guide columns that are spaced apart from each other. The guide columns are vertically arranged and are slidably connected to the cabinet mounting assembly 530 .

[0095] For example, the guide assembly 540 may include two guide posts spaced apart on the left and right sides, and the two guide posts are slidably connected to the left and right ends of the cabinet mounting assembly 530 respectively.

[0096] In some possible embodiments, the cabinet drive assembly 520 includes a screw 521, a nut, and a cabinet drive device 522. The screw 521 is vertically arranged and rotationally connected to the frame assembly 510. The nut is threadedly connected to the screw 521, and the nut is fixedly connected to the cabinet mounting assembly 530. The cabinet drive device 522 is disposed on the frame assembly 510. The output end of the cabinet drive device 522 is transmission-connected to the screw 521, and the cabinet drive device 522 is used to drive the screw 521 to rotate.

[0097] In this way, the cooperation between the screw rod 521 and the nut facilitates the lifting and lowering of the test cabinet 400. Furthermore, the cooperation between the screw rod 521 and the nut facilitates precise vertical positioning of the test cabinet 400, thereby facilitating alignment of the test cavity 410 with the hard disk pushing mechanism 300, and thereby facilitating the hard disk pushing mechanism 300 to efficiently and smoothly push the hard disk into the test cavity 410, as well as efficiently and smoothly pull the hard disk out of the test cavity 410. Furthermore, the self-locking function of the screw rod 521 and the nut can be utilized to lock the test cabinet 400, and the overall structure of the lifting mechanism 500 is relatively simple.

[0098] Exemplarily, the cabinet driving device 522 may be a rotary motor, and the cabinet driving device 522 may be disposed at the top end of the screw rod 521 .

[0099] In some possible implementations, the test cabinet 400 is detachably connected to the lifting mechanism 500 . Specifically, the test cabinet 400 is detachably connected to the cabinet mounting assembly 530 .

[0100] In this way, the test cabinet 400 can be replaced according to different test requirements to meet a variety of different test scenarios, making the hard disk detection device more versatile.

[0101] In some possible embodiments, the lifting mechanism 500 clamps and secures the test cabinet 400. Specifically, the cabinet mounting assembly 530 includes an upper clamping member 531 and a lower clamping member 532, which are arranged one above the other and are slidably connected to the frame assembly 510 via a guide assembly 540. The test cabinet 400 is disposed between the upper clamping member 531 and the lower clamping member 532, and is clamped and secured by the upper clamping member 531 and the lower clamping member 532.

[0102] This makes it easier to assemble and disassemble the test cabinet 400 on the lifting mechanism 500. Furthermore, the test cabinet 400 is clamped by the upper clamping members 531 and the lower clamping members 532, located on the upper and lower sides of the test cabinet 400, respectively. This provides a more stable clamping of the test cabinet 400 and prevents the test cabinet 400 from falling off. Furthermore, both the upper clamping members 531 and the lower clamping members 532 are slidably connected to the frame assembly 510 via the guide assembly 540, making them less likely to shift, thereby facilitating efficient and stable clamping of the test cabinet 400.

[0103] Figure 4 A schematic diagram of a lifting mechanism provided in an embodiment of the present application.

[0104] like Figure 4 As shown, in some possible implementations, the cabinet installation assembly 530 further includes a middle structural member 533 , a clamping drive component 534 and a clamping synchronization component 535 .

[0105] The middle structural member 533 is arranged between the upper clamping member 531 and the lower clamping member 532. The middle structural member 533 is slidingly connected to the frame assembly 510 through the guide assembly 540. The output end of the cabinet drive assembly 520 is transmission-connected to the middle structural member 533. The cabinet drive assembly 520 is used to drive the middle structural member 533 to rise and fall.

[0106] The clamping drive component 534 is provided on the middle structural member 533. The output end of the clamping drive component 534 is transmission-connected to the upper clamping member 531 and the lower clamping member 532 via the clamping synchronization component 535. The clamping drive component 534 is used to drive the upper clamping member 531 and the lower clamping member 532 to open and close synchronously.

[0107] Thus, through the transmission of the clamping synchronization component 535, the clamping drive component 534 can drive the upper clamping member 531 and the lower clamping member 532 to open and close synchronously. The upper clamping member 531 and the lower clamping member 532 can respectively apply clamping force to the upper and lower sides of the test cabinet 400, thereby reducing the clamping force required by the clamping drive component 534. Furthermore, the synchronous opening and closing of the upper clamping member 531 and the lower clamping member 532 can create a larger opening between the upper clamping member 531 and the lower clamping member 532 and improve the opening and closing efficiency, thereby facilitating efficient assembly and disassembly of the test cabinet 400. Furthermore, the upper clamping member 531, the lower clamping member 532, and the middle structural member 533 are all slidably connected to the frame assembly 510 via the guide assembly 540. This makes it difficult for the upper clamping member 531, the lower clamping member 532, and the middle structural member 533 to shift, thereby facilitating efficient and stable clamping of the test cabinet 400. In addition, the output end of the cabinet drive component 520 is connected to the middle structure 533 for driving the middle structure 533 to rise and fall, so that the opening and closing of the upper clamping member 531 and the lower clamping member 532 is not likely to affect the cabinet drive component 520.

[0108] In some examples where the cabinet drive assembly 520 includes a screw rod 521, a nut, and a cabinet drive device 522, the nut is fixedly connected to the middle structure 533. For example, the nut can be fixedly connected to the middle structure 533 by fasteners or the like.

[0109] In some possible implementations, the clamping synchronization component 535 includes a first connecting rod 5351 , a second connecting rod 5352 , a third connecting rod 5353 , a fourth connecting rod 5354 , a first push-pull rod 5355 , and a second push-pull rod 5356 .

[0110] One end of the first link 5351 is hinged to one end of the second link 5352 and one end of the first push-pull rod 5355, the other end of the second link 5352 is hinged to one end of the third link 5353, the other end of the third link 5353 is hinged to one end of the fourth link 5354 and one end of the second push-pull rod 5356, the other end of the fourth link 5354 is hinged to the other end of the first link 5351, and the first link 5351, the second link 5352, the third link 5353 and the fourth link 5354 form a four-link structure.

[0111] The other end of one of the first push-pull rod 5355 and the second push-pull rod 5356 is hinged to the upper clamping member 531 , and the other end of the other of the first push-pull rod 5355 and the second push-pull rod 5356 is hinged to the lower clamping member 532 .

[0112] The first link 5351 is arranged parallel to the third link 5353, the second link 5352 is arranged parallel to the fourth link 5354, the middle part of the first link 5351 is rotatably connected to the middle structure 533 through the first connecting shaft, and the middle part of the third link 5353 is rotatably connected to the middle structure 533 through the second connecting shaft.

[0113] The clamping drive component 534 is used to drive the upper clamping member 531 and the lower clamping member 532 to open and close synchronously through the first connecting rod 5351 , the second connecting rod 5352 , the third connecting rod 5353 , the fourth connecting rod 5354 , the first push-pull rod 5355 and the second push-pull rod 5356 .

[0114] In this way, the upper clamping member 531 and the lower clamping member 532 can be opened and closed synchronously by driving the clamping driving component 534 .

[0115] Illustratively, the first connecting rod 5351 and the second connecting rod 5352 can swing synchronously under the drive of the clamping drive component 534, so as to drive the first push-pull rod 5355 and the second push-pull rod 5356 to synchronously push and pull the upper clamping member 531 and the lower clamping member 532, thereby realizing the synchronous opening and closing of the upper clamping member 531 and the lower clamping member 532.

[0116] Illustratively, the output end of the clamping drive component 534 can be connected to at least one of the first link 5351, the second link 5352, the third link 5353 and the fourth link 5354, and can drive the first link 5351, the second link 5352, the third link 5353 and the fourth link 5354 to move, thereby driving the first link 5351, the second link 5352, the third link 5353, the fourth link 5354, the first push-pull rod 5355 and the second push-pull rod 5356 to move as a whole.

[0117] Illustratively, the first link 5351 and the third link 5353 are arranged vertically, with the first link 5351 located above the third link 5353, and the second link 5352 and the fourth link 5354 are arranged horizontally, with the second link 5352 located to the right of the fourth link 5354. The right end of the first link 5351 is hinged to the lower end of the first push-pull rod 5355, and the upper end of the first push-pull rod 5355 is hinged to the upper clamping member 531. The left end of the third link 5353 is hinged to the upper end of the second push-pull rod 5356, and the lower end of the second push-pull rod 5356 is hinged to the lower clamping member 532.

[0118] Exemplarily, the clamping drive component 534 may include a first telescopic drive component, the lower end of which is connected to the middle structural component 533 , and the upper end of which is hinged to the left end of the first connecting rod 5351 .

[0119] When the first telescopic driving component extends and drives the left end of the first connecting rod 5351 to swing upward, the right end of the first connecting rod 5351 swings downward and the left end of the third connecting rod 5353 swings upward, driving the first push-pull rod 5355 to move downward and the second push-pull rod 5356 to move upward, and then driving the upper clamping member 531 and the lower clamping member 532 to move closer to the middle structural member 533, thereby realizing the clamping of the upper clamping member 531 and the lower clamping member 532 on the test cabinet 400.

[0120] When the first telescopic driving component shortens and drives the left end of the first connecting rod 5351 to swing downward, the right end of the first connecting rod 5351 swings upward and the left end of the third connecting rod 5353 swings downward, driving the first push-pull rod 5355 to move upward and the second push-pull rod 5356 to move downward, thereby driving the upper clamping member 531 and the lower clamping member 532 to move away from the middle structural member 533, thereby realizing the opening of the upper clamping member 531 and the lower clamping member 532.

[0121] In some examples, the clamping drive component 534 may further include a second telescopic drive component. The upper end of the second telescopic drive component is connected to the middle structural member 533, and the lower end of the second telescopic drive component is hinged to the right end of the third connecting rod 5353. When the first telescopic drive component extends, the second telescopic drive component shortens. When the first telescopic drive component shortens, the second telescopic drive component extends. This provides a greater push and pull force on the upper clamping member 531 and the lower clamping member 532.

[0122] Exemplarily, the first telescopic driving component and the second telescopic driving component may both be cylinders.

[0123] Figure 5 A schematic diagram of a test cabinet of a hard disk detection module provided in an embodiment of the present application.

[0124] like Figure 5 As shown, in some possible implementations, the inner wall of the test cavity 410 has a hard disk guide structure 420 extending in the front-to-back direction, and the hard disk guide structure 420 is used to guide the hard disk to move back and forth in the test cavity 410.

[0125] Along the front-to-back direction, a test terminal 430 is provided on the inner wall of the test cavity 410 on the side away from the hard disk pushing mechanism 300. The test terminal 430 is used to electrically contact the hard disk pushed into the test cavity 410. After the hard disk pushed into the test cavity 410 electrically contacts the test terminal 430, the hard disk can be tested.

[0126] In this way, it is convenient to push the hard disk smoothly into the test cavity 410 and implement the detection of the hard disk pushed into the test cavity 410. It is also convenient to smoothly pull the hard disk that has completed the detection out of the test cavity 410 after completing the detection of the hard disk.

[0127] For example, after the hard disk is pushed into the test cavity 410, it can be plugged into the test terminal 430. The hard disk can be pulled out from the test terminal 430 under the action of a pulling force.

[0128] For example, the test terminal 430 may be a probe.

[0129] Figure 6 This is a schematic diagram of a hard disk pushing mechanism of a hard disk detection module provided in an embodiment of the present application. Figure 7 This is another schematic diagram of a hard disk pushing mechanism of a hard disk detection module provided in an embodiment of the present application. Figure 8 A schematic diagram of a hard disk pushing mechanism provided in an embodiment of the present application. Figure 9 Another schematic diagram of a hard disk pushing mechanism provided in an embodiment of the present application.

[0130] like Figure 6 As shown, in some possible implementations, the hard disk pushing mechanism 300 includes a fixing plate 310 , a hard disk receiving platform 320 , a pushing member 330 and a pushing drive device 340 .

[0131] The hard disk receiving platform 320 and the driving device 340 are disposed on the fixed plate 310 . The output end of the driving device 340 is in transmission connection with the pushing member 330 . The driving device 340 is used to drive the pushing member 330 to move forward and backward.

[0132] The first hard disk pick-and-place module M2 is used to deliver the picked hard disk to the hard disk receiving platform 320 , and the pusher 330 moving toward the test cabinet 400 is used to push the hard disk placed on the hard disk receiving platform 320 into the test cabinet 400 .

[0133] In this way, it is easy to automatically push the hard disk from the hard disk pushing mechanism 300 into the test cabinet 400 .

[0134] Exemplarily, the pushing drive device 340 may be an electric cylinder.

[0135] Exemplarily, the hard disk receiving platform 320 is fixedly disposed above the fixing plate 310 .

[0136] In some examples where the hard disk detection device includes the second hard disk pick-and-place module M3 , the second hard disk pick-and-place module M3 is used to remove the hard disk from the hard disk receiving platform 320 , making it more convenient to automatically remove the hard disk from the hard disk pushing mechanism 300 .

[0137] like Figure 7-Figure 9As shown, in some possible embodiments, the hard drive pushing mechanism 300 further includes an electromagnet 370, which is disposed at the end of the pushing member 330 facing the test cabinet 400. The pushing member 330, which moves away from the test cabinet 400, is used to pull the hard drive from the test cabinet 400 to the hard drive receiving platform 320 through the magnetic attraction of the electromagnet 370.

[0138] In this way, it is convenient to take out the hard disk that has completed the test from the test cabinet 400, so that the second hard disk retrieval module M3 can take away the hard disk that has completed the test, thereby facilitating the automatic storage of the hard disk that has completed the test.

[0139] In some examples, the fixed plate 310 has a guide rail 311 extending in the front-to-back direction, and the pusher 330 is slidably connected to the fixed plate 310 via the guide rail 311 . The guide rail 311 is used to guide the pusher 330 to slide back and forth.

[0140] In this way, the pushing member 330 can move forward and backward more stably, making it easier to push the hard disk into the test cabinet 400 and to smoothly pull the hard disk out of the test cabinet 400 to the position to be removed, making it easier for the hard disk pushed into the test cabinet 400 to be stably docked with the test terminal 430, and for the second hard disk pick-up and placement module M3 to remove the hard disk that has completed testing from the hard disk receiving platform 320.

[0141] Illustratively, the guide rail 311 is disposed on the upper surface of the fixing plate 310 .

[0142] In some possible embodiments, the hard drive receiving platform 320 has a hard drive guide slot 321 extending in a front-to-back direction. The hard drive guide slot 321 is open at the end facing the test cabinet 400, and a pusher 330 is disposed within the hard drive guide slot 321. The first hard drive placement module M2 is configured to insert a hard drive into the hard drive guide slot 321, which is configured to guide the hard drive in forward and backward movement. The pusher 330, which moves toward the test cabinet 400, is configured to push a hard drive placed in the hard drive guide slot 321 along the hard drive guide slot 321 into the test cabinet 400.

[0143] In this way, the hard disk moves stably back and forth on the hard disk receiving platform 320, making it easy to push the hard disk smoothly into the test cabinet 400 and to pull the hard disk smoothly out of the test cabinet 400 to the position to be removed. It is also easy for the hard disk pushed into the test cabinet 400 to be stably docked with the test terminal 430, and for the second hard disk picking and placing module M3 to take the hard disk that has completed testing from the hard disk receiving platform 320.

[0144] In some examples where the hard disk detection device includes the second hard disk pick-up and placement module M3 , the second hard disk pick-up and placement module M3 is used to remove the hard disk from the hard disk guide slot 321 .

[0145] In some possible implementations, the hard drive pushing mechanism 300 includes a plurality of pushers 330 arranged in a row along the left-right direction. The ends of the pushers 330 facing away from the test cabinet 400 are fixedly connected to a synchronizer 360 . The pushers 330 are slidably connected to the guide rails 311 via the synchronizer 360 . The output end of the push drive 340 is in transmission connection with the synchronizer 360 . The push drive 340 is configured to drive the plurality of pushers 330 forward and backward via the synchronizer 360 .

[0146] In this way, multiple hard disks can be pushed into multiple test cavities 410 for testing simultaneously through multiple pushers 330, and multiple hard disks can be pulled out from multiple test cavities 410 simultaneously, so as to realize efficient automatic testing of a large number of hard disks.

[0147] Illustratively, the synchronizer 360 may be a strip-shaped member extending in the left-right direction, and the left and right ends of the synchronizer 360 are respectively slidably connected to a guide rail 311 .

[0148] Exemplarily, the hard disk receiving platform 320 has a plurality of hard disk guide slots 321 corresponding to the pushing members 330 , and the pushing members 330 are disposed in the corresponding hard disk guide slots 321 .

[0149] Exemplarily, the hard disk receiving platform 320 includes a plurality of receiving sub-platforms corresponding one-to-one to the pushing members 330 , and the hard disk guide grooves 321 corresponding to the pushing members 330 are provided on the corresponding receiving sub-platforms.

[0150] In some possible embodiments, the pushing drive device 340 and the synchronizing member 360 are both arranged below the hard disk receiving platform 320. The hard disk receiving platform 320 has an avoidance opening 322 corresponding to the pushing member 330 one by one. The pushing member 330 is passed through the corresponding avoidance opening 322. Part of the pushing member 330 is located below the hard disk receiving platform 320, and part of the pushing member 330 is located above the hard disk receiving platform 320. The avoidance opening 322 is used for the corresponding pushing member 330 to move forward and backward.

[0151] In this way, the driving device 340 and the synchronizer 360 are unlikely to affect the placement and removal of the hard disk on the hard disk carrying platform.

[0152] In the example where the hard disk receiving platform 320 has a hard disk guide groove 321 , the avoidance opening 322 is located at the bottom of the hard disk guide groove 321 and communicates with the hard disk guide groove 321 .

[0153] For example, the hard disk receiving platform 320 may be spaced above the fixing plate 310 by a supporting structure.

[0154] Exemplarily, the synchronizer 360 is disposed between the hard disk receiving platform 320 and the fixing plate 310 .

[0155] Exemplarily, the hard drive pushing mechanism 300 further includes a carrier plate 350, which is fixedly connected to the frame assembly 510 of the lifting mechanism 500. The fixed plate 310 is spaced above the carrier plate 350 via support columns. The driving device 340 is disposed between the carrier plate 350 and the fixed plate 310 and can be fixedly connected to the bottom surface of the fixed plate 310. The fixed plate 310 has a strip-shaped avoidance hole extending in the front-to-back direction. The output end of the driving device 340 is connected to the synchronizer 360 via a transmission rod extending through the avoidance hole, and the avoidance hole is used to allow the transmission rod to move forward and backward.

[0156] Figure 10 A schematic diagram of another hard disk detection device provided in an embodiment of the present application.

[0157] like Figure 10 As shown, in some possible implementations, the first hard disk pick-and-place module M2 includes a first tray moving mechanism 100 and a first hard disk moving mechanism 200 , and the hard disk detection device further includes a hard disk separation compartment A2 .

[0158] The first material bin A1, the first empty disk bin A3 and the hard disk separation bin A2 are located above the first tray moving mechanism 100, and are arranged in a row in the front-to-back direction.

[0159] The hard disk separation bin A2 and the hard disk detection module M1 are arranged on the left and right. The first hard disk moving mechanism 200 is located above the hard disk separation bin A2. The first material bin A1 and the first empty disk bin A3 are located on the front and back sides of the first hard disk moving mechanism 200 respectively.

[0160] The first tray moving mechanism 100 is used to take out the first tray T1 containing hard disks from the first material bin A1 and send the first tray T1 containing hard disks to the hard disk separation bin A2.

[0161] The first hard disk moving mechanism 200 is used to remove the hard disk from the first tray T1 sent to the hard disk separation chamber A2 and send the hard disk to the hard disk detection module M1.

[0162] The first tray moving mechanism 100 is further used to move the empty first tray T1 from the hard disk separation bin A2 to the first empty disk bin A3 after the hard disks on the first tray T1 are removed.

[0163] In this way, it is easy to automatically remove the hard disk from the first tray T1 loaded with hard disks, send the removed hard disk to the hard disk detection module M1 for detection, and recycle the empty first tray T1 after the hard disk on the first tray T1 is removed.

[0164] Exemplarily, the hard drive separation bin A2 and the hard drive pushing mechanism 300 are arranged on the left and right sides, and the first hard drive moving mechanism 200 is located above the hard drive pushing mechanism 300. The first hard drive moving mechanism 200 is used to deliver hard drives to the hard drive pushing mechanism 300, and the hard drive pushing mechanism 300 is used to push hard drives from the first hard drive moving mechanism 200 into the test cabinet 400.

[0165] In an example where the test cabinet 400 is provided on a lifting mechanism 500 and the test cabinet 400 has a plurality of test cavities 410 arranged vertically, the hard disk pushing mechanism 300 is used to push the hard disk from the first hard disk moving mechanism 200 into the test cavity 410 opposite to the hard disk pushing mechanism 300 .

[0166] In some examples where the hard disk pushing mechanism 300 includes a hard disk receiving platform 320 , the first hard disk moving mechanism 200 is used to place the hard disk onto the hard disk receiving platform 320 .

[0167] In some examples where the hard disk receiving platform 320 has a hard disk guide slot 321 , the first hard disk moving mechanism 200 is used to place the hard disk into the hard disk guide slot 321 .

[0168] In some possible implementations, the second hard disk retrieval module M3 includes a second tray moving mechanism 700 and a second hard disk moving mechanism 600, and the hard disk detection device further includes a hard disk loading compartment A5.

[0169] The second material bin A4, the second empty disk bin A6 and the hard disk loading bin A5 are located above the second pallet moving mechanism 700, and are arranged in a row in the front-to-back direction.

[0170] The hard disk separation bin A2 and the hard disk loading bin A5 are respectively located on the left and right sides of the hard disk detection module M1. The second hard disk moving mechanism 600 and the first hard disk moving mechanism 200 are arranged on the left and right. The second hard disk moving mechanism 600 is located above the hard disk loading bin A5. The second material bin A4 and the second empty disk bin A6 are respectively located on the front and back sides of the second hard disk moving mechanism 600.

[0171] The second tray moving mechanism 700 is used to take out an empty second tray T2 from the second empty disk bin A6 and send the empty second tray T2 to the hard disk loading bin A5.

[0172] The second hard disk moving mechanism 600 is used to remove the hard disk from the hard disk detection module M1 and load the hard disk into the second tray T2 of the hard disk loading compartment A5.

[0173] The second tray moving mechanism 700 is further configured to move the second tray T2 loaded with hard disks from the hard disk loading bin A5 to the second material bin A4 after the hard disks are loaded into the second tray T2.

[0174] In this way, it is easy to automatically load the hard disk after the hard disk is tested into the second tray T2 for storage.

[0175] Exemplarily, the hard disk separation bin A2 and the hard disk loading bin A5 are respectively located on the left and right sides of the hard disk pushing mechanism 300, and the second hard disk moving mechanism 600 is located above the hard disk pushing mechanism 300. The second hard disk moving mechanism 600 is used to remove the hard disk from the hard disk pushing mechanism 300.

[0176] In some examples where the hard disk pushing mechanism 300 includes a hard disk receiving platform 320 , the second hard disk moving mechanism 600 is used to remove the hard disk from the hard disk receiving platform 320 .

[0177] In some examples where the hard disk receiving platform 320 has a hard disk guide groove 321 , the second hard disk moving mechanism 600 is used to remove the hard disk from the hard disk guide groove 321 .

[0178] Figure 11 This is a schematic diagram of a first tray moving mechanism of a hard disk detection device provided in an embodiment of the present application. Figure 12 This is another schematic diagram of the first tray moving mechanism of a hard disk detection device provided in an embodiment of the present application. Figure 13 This is another schematic diagram of the first tray moving mechanism of a hard disk detection device provided in an embodiment of the present application. Figure 14 A schematic diagram of a first tray moving mechanism provided in an embodiment of the present application.

[0179] like Figure 11 、 Figure 12 As shown, in some possible implementations, the first pallet moving mechanism 100 includes a first linear conveying assembly 110 , a first bearing assembly 120 , a first lifting assembly 130 , a second lifting assembly 140 and a third lifting assembly 150 .

[0180] The first linear conveying assembly 110 is in transmission connection with the first bearing assembly 120 , and the first linear conveying assembly 110 is used to drive the first bearing assembly 120 to move forward and backward.

[0181] The first lifting assembly 130 is disposed below the first material bin A1 , the second lifting assembly 140 is disposed below the hard disk separation bin A2 , and the third lifting assembly 150 is disposed below the first empty disk bin A3 .

[0182] The first lifting assembly 130 is used to take out the first tray T1 containing hard disks from the first material bin A1 and place the first tray T1 containing hard disks on the first carrying assembly 120 .

[0183] The second lifting assembly 140 is used to lift the first tray T1 loaded with hard disks from the first supporting assembly 120 to the hard disk separation chamber A2, and to place the empty first tray T1 from the hard disk separation chamber A2 to the first supporting assembly 120 after the hard disks on the first tray T1 are removed.

[0184] The third lifting assembly 150 is used to lift the empty first tray T1 from the first carrying assembly 120 to the first empty tray bin A3. The first carrying assembly 120 is used to drive the first tray T1 placed thereon to move forward and backward.

[0185] In this way, it is convenient to automatically take out the first tray T1 containing hard disks from the first material warehouse A1 and send it to the hard disk separation warehouse A2 for the first hard disk moving mechanism 200 to take the hard disks out of the first tray T1, and after the hard disks on the first tray T1 are taken out, send the empty first tray T1 from the hard disk separation warehouse A2 to the first empty disk warehouse A3.

[0186] Illustratively, the first, second, and third jacking assemblies 130, 140, and 150 are all jackable components. When the first jacking assembly 130 is raised, the first tray T1 containing hard disks in the first material bin A1 can be dropped onto the first jacking assembly 130. When the second and third jacking assemblies 140, 150 are raised, the first tray T1 can be lifted. When the first and second jacking assemblies 130, 140 are lowered, the first tray T1 can be placed onto the first supporting assembly 120.

[0187] Exemplarily, the first lifting assembly 130 , the second lifting assembly 140 and the third lifting assembly 150 may all be vertically arranged cylinders.

[0188] In some possible implementations, the first material bin A1 is provided with a first clamping assembly 810 for clamping the side walls of the first trays T1 so that the first trays T1 containing hard disks can be stacked and stored in the first material bin A1.

[0189] After the first jacking assembly 130 rises to the first pallet T1 at the bottom layer of the first material bin A1, the first clamping assembly 810 is opened to allow the first pallet T1 stored in the first material bin A1 to fall to the first jacking assembly 130, and the first clamping assembly 810 clamps the first pallet T1 above the first pallet T1 at the bottom layer of the first material bin A1, so that the first jacking assembly 130 takes out the first pallet T1 at the bottom layer of the first material bin A1.

[0190] In this way, it is easy to store the first tray T1 containing hard disks in the first material warehouse A1 and the first lifting assembly 130 picks up the first tray T1 containing hard disks from the first material warehouse A1.

[0191] Exemplarily, first trays T1 loaded with hard disks are stacked in the first material bin A1.

[0192] For example, after the first jacking assembly 130 rises to the first pallet T1 on the bottom layer of the first material warehouse A1, the first clamping assembly 810 opens, so that all the first pallets T1 stored in the first material warehouse A1 fall to the top surface of the first jacking assembly 130, and then the first jacking assembly 130 is raised and lowered, so that the first pallet T1 on the second layer from bottom to top is opposite to the first clamping assembly 810, and the first clamping assembly 810 clamps the first pallet T1 on the second layer from bottom to top, and then the first jacking assembly 130 is lowered, and the first pallet T1 on the bottom layer falls to the first supporting assembly 120 along with the first jacking assembly 130.

[0193] In some possible implementations, the first empty tray bin A3 is provided with a second clamping assembly 820 , and the second clamping assembly 820 is used to clamp the side of the first tray T1 .

[0194] After the third lifting assembly 150 lifts the empty first tray T1 to the first empty tray bin A3, the second clamping assembly 820 clamps the first tray T1 lifted to the first empty tray bin A3 by the third lifting assembly 150, so that the empty first tray T1 is stacked and stored in the first empty tray bin A3.

[0195] In this way, it is convenient to store the empty first tray T1 after the hard disks on the first tray T1 are removed into the first empty disk storage bin A3, so as to realize the recycling of the first empty disk stock.

[0196] Exemplarily, the empty first trays T1 are stacked in the first empty tray magazine A3.

[0197] Illustratively, when the third lifting assembly 150 lifts the empty first pallet T1 to the first empty disk bin A3, the second clamping assembly 820 opens first, causing the first pallet T1 stored in the first empty disk bin A3 to fall onto the first pallet T1 lifted by the third lifting assembly 150. The third lifting assembly 150 raises the bottom layer of the first pallet T1 lifted by it to a position opposite to the second clamping assembly 820, and then causes the second clamping assembly 820 to clamp the bottom layer of the first pallet T1 lifted by the third lifting assembly 150 to store the empty first pallet T1 in the first empty disk bin A3.

[0198] like Figure 11-14 As shown, in some possible embodiments, the first linear conveying assembly 110 includes a first linear guide rail 111, a second linear guide rail 112, a first linear drive device 113, and a first synchronization assembly 114. The first linear guide rail 111 and the second linear guide rail 112 are arranged side by side and spaced apart, and both extend in the front-to-back direction.

[0199] The first bearing assembly 120 includes a first bearing member 122 and a second bearing member 123 arranged side by side. The first bearing member 122 and the second bearing member 123 are spaced apart from each other. The first bearing member 122 is slidably connected to the first linear slide 111, and the second bearing member 123 is slidably connected to the second linear slide 112. The first bearing member 122 and the second bearing member 123 are transmission-connected via a first synchronization assembly 114. A first linear drive device 113 is provided on the first linear slide 111. The output end of the first linear drive device 113 is transmission-connected to the first bearing member 122. The first linear drive device 113 is used to drive the first bearing member 122 to move forward and backward, and drives the second bearing member 123 to move forward and backward synchronously via the first synchronization assembly 114.

[0200] Along the left-right direction, the first lifting assembly 130 , the second lifting assembly 140 and the third lifting assembly 150 are located between the first linear slide rail 111 and the second linear slide rail 112 , and between the first bearing member 122 and the second bearing member 123 .

[0201] The first lifting assembly 130 is used to place the first tray T1 containing hard disks onto the first supporting member 122 and the second supporting member 123 .

[0202] The second lifting assembly 140 is used to place the empty first tray T1 from the hard disk separation compartment A2 to the first carrier 122 and the second carrier 123 after the hard disks on the first tray T1 are removed.

[0203] The first supporting member 122 and the second supporting member 123 are used to drive the first tray T1 placed thereon to move forward and backward.

[0204] In this way, the first linear conveying assembly 110 drives the first pallet T1 forward and backward through the first bearing assembly 120, and the lifting and lowering of the first pallet T1 by the first lifting assembly 130, the second lifting assembly 140, and the third lifting assembly 150 are less likely to affect each other. This facilitates the automatic removal of the first pallet T1 loaded with hard disks from the first material bin A1 and its delivery to the hard disk separation bin A2 for the first hard disk moving mechanism 200 to remove the hard disks from the first pallet T1, and the delivery of the empty first pallet T1 from the hard disk separation bin A2 to the first empty disk bin A3 after the hard disks on the first pallet T1 are removed. In addition, the first bearing member 122 and the second bearing member 123 can be simultaneously driven forward and backward by a first linear drive device 113, resulting in good synchronization between the first bearing member 122 and the second bearing member 123 and a relatively simple overall structure.

[0205] Exemplarily, the first linear drive device 113 may be an electric cylinder.

[0206] Exemplarily, the first supporting member 122 and the second supporting member 123 are both strip-shaped members extending in the front-to-back direction.

[0207] Exemplarily, the first synchronization assembly 114 includes a first belt mechanism, a second belt mechanism, a first synchronization rod and a second synchronization rod. The first belt mechanism and the second belt mechanism are arranged opposite to each other on the left and right. The first carrier 122 is fixedly connected to the belt of the first belt mechanism, and the second carrier 123 is fixedly connected to the belt of the second belt mechanism. The front drive wheel of the first belt mechanism and the front drive wheel of the second belt mechanism are coaxially fixedly connected through the first synchronization rod, and the rear drive wheel of the first belt mechanism and the rear drive wheel of the second belt mechanism are coaxially fixedly connected through the second synchronization rod.

[0208] like Figure 14 As shown, in some possible implementations, the top surface of the first carrying assembly 120 has a first pallet placement position P1 and a second pallet placement position P2 arranged in a front-to-back manner.

[0209] Both the first pallet placement position P1 and the second pallet placement position P2 are provided with a first positioning structure 121 , which is used to cooperate with a first matching structure on the bottom surface of the first pallet T1 to achieve positioning of the first pallet T1 and the first carrying assembly 120 .

[0210] When the first pallet placement position P1 is located below the first material bin A1, the second pallet placement position P2 is located below the hard disk separation bin A2. When the first pallet placement position P1 is located below the hard disk separation bin A2, the second pallet placement position P2 is located below the first empty disk bin A3.

[0211] The first lifting assembly 130 is used to place the first tray T1 loaded with hard disks to the first tray placement position P1 when the first tray placement position P1 is located below the first material bin A1.

[0212] The second lifting assembly 140 is used to lift the first tray T1 loaded with hard disks from the first tray placement position P1 to the hard disk separation bin A2 when the first tray placement position P1 is located below the hard disk separation bin A2, and is used to place the empty first tray T1 from the hard disk separation bin A2 to the second tray placement position P2 when the second tray placement position P2 is located below the hard disk separation bin A2.

[0213] The third lifting assembly 150 is used to lift the empty first pallet T1 from the second pallet placement position P2 to the first empty pallet bin A3 when the second pallet placement position P2 is located below the first empty pallet bin A3.

[0214] In this way, the first pallet T1 can be shifted between the first pallet placement position P1 and the second pallet placement position P2 by raising and lowering the second lifting assembly 140. Furthermore, the first pallet T1 can be moved a certain distance by the first carrying assembly 120 and then repositioned, thereby improving the positioning accuracy of the first pallet T1 and facilitating the automated movement of the first pallet T1. Furthermore, the coordination of the first linear conveying assembly 110, the first lifting assembly 130, the second lifting assembly 140, and the third lifting assembly 150 allows the first pallet placement position P1 and the second pallet placement position P2 to operate simultaneously, thereby improving work efficiency.

[0215] Exemplarily, the first linear conveying assembly 110 drives the first bearing assembly 120 to reciprocate in the front-to-back direction. When the first pallet placement position P1 is located below the first material bin A1, the first lifting assembly 130 picks up the first pallet T1 containing hard disks from the first material bin A1 and places the first pallet T1 containing hard disks to the first pallet placement position P1. The first linear conveying assembly 110 then drives the first bearing assembly 120 to a position where the first pallet placement position P1 is located below the hard disk separation bin A2 and the second pallet placement position P2 is located below the first empty disk bin A3. At this time, the second lifting assembly 140 rises to lift the first pallet T1 containing hard disks from the first pallet placement position P1 to the hard disk separation bin A2. After the first pallet T1 containing hard disks is lifted up from the first pallet placement position P1 by the second lifting assembly 140, the first linear conveying assembly 110 drives the first carrying assembly 120 to move to a position where the first pallet placement position P1 is located below the first material warehouse A1 and the second pallet placement position P2 is located below the hard disk separation warehouse A2. At this time, the first lifting assembly 130 picks up the first pallet T1 containing hard disks from the first material warehouse A1 again and places the first pallet T1 containing hard disks to the first pallet placement position P1. The second lifting assembly 140 places the empty first pallet T1 from the hard disk separation warehouse A2 to the second pallet placement position P2. Next, the first linear conveyor assembly 110 drives the first carrier assembly 120 to a position where the first tray position P1 is located below the hard drive separation bin A2 and the second tray position P2 is located below the first empty disk bin A3. At this point, the second lifting assembly 140 rises to lift the loaded first tray T1 from the first tray position P1 to the hard drive separation bin A2. The third lifting assembly 150 rises to lift the empty first tray T1 from the second tray position P2 to the first empty disk bin A3. This allows the first tray position P1 and the second tray position P2 to operate simultaneously, increasing the efficiency of the hard drive testing equipment.

[0216] Illustratively, the first positioning structure 121 includes a plurality of first positioning pins spaced apart from each other, and both the first carrier 122 and the second carrier 123 are provided with first positioning pins. The first mating structure includes first positioning holes provided on the bottom surface of the first tray T1, the first positioning holes being provided in correspondence with the first positioning pins, and the first positioning pins being configured to be inserted into the corresponding first positioning holes.

[0217] Figure 15 This is a schematic diagram of a first lifting component of a first pallet moving mechanism provided in an embodiment of the present application.

[0218] like Figure 15 As shown, in some possible implementations, a suction cup assembly 160 is provided on the top of the first jacking assembly 130 , the second jacking assembly 140 , and the third jacking assembly 150 .

[0219] In this way, when the first pallet T1 is placed above the first lifting assembly 130, the second lifting assembly 140, and the third lifting assembly 150, the first pallet T1 is securely positioned and unlikely to shift. The first pallet T1 reaches each transfer position with high accuracy, facilitating the automated movement of the first pallet T1. Furthermore, when the suction cup assembly 160 located above the first lifting assembly 130 picks up the first pallet T1 loaded with hard drives from the first material bin A1, it can pull the first pallet T1 loaded with hard drives out of the first material bin A1 by sucking on the bottom surface of the first pallet T1.

[0220] Exemplarily, the suction cup assembly 160 provided on the top of the first lifting assembly 130, the second lifting assembly 140 and the third lifting assembly 150 includes a plurality of suction cups distributed in an array to facilitate adsorption of multiple positions of the first pallet T1, so that the top suction cup assembly 16 provided on the first lifting assembly 130, the second lifting assembly 140 and the third lifting assembly 150 can adsorb the first pallet T1 more stably.

[0221] Figure 16 This is a schematic diagram of a first clamping assembly clamping a first tray according to an embodiment of the present application. Figure 17 for Figure 16 A schematic diagram of the first clamping assembly is provided in .

[0222] like Figure 16 、 Figure 17 As shown, in some possible embodiments, the first clamping assembly 810 includes a first clamping drive device 811, a second clamping drive device 812, and a first clamping plate 813, a second clamping plate 814, a third clamping plate 815 and a fourth clamping plate 816 connected end to end.

[0223] The first clamping plate 813 and the third clamping plate 815 are disposed opposite to each other, and the second clamping plate 814 and the fourth clamping plate 816 are disposed opposite to each other.

[0224] The first clamping plate 813 and the second clamping plate 814, the second clamping plate 814 and the third clamping plate 815, the third clamping plate 815 and the fourth clamping plate 816, and the fourth clamping plate 816 and the first clamping plate 813 are all connected through the transmission groove 817 and the transmission pin 818 passed through the transmission groove 817, and the transmission pin 818 can slide along the transmission groove 817.

[0225] The output end of the first clamping drive device 811 is transmission-connected to the first clamping plate 813, and the output end of the second clamping drive device 812 is transmission-connected to the third clamping plate 815. The first clamping drive device 811 and the second clamping drive device 812 are used to drive the first clamping plate 813 and the third clamping plate 815 to move toward or away from each other, and drive the second clamping plate 814 and the fourth clamping plate 816 to move toward or away from each other synchronously through the transmission groove 817 and the transmission pin 818.

[0226] In this way, the first clamping drive device 811 and the second clamping drive device 812 can be driven to make the first clamping plate 813, the second clamping plate 814, the third clamping plate 815 and the fourth clamping plate 816 clamp the first pallet T1 from four sides, thereby firmly clamping the first pallet T1, and the structure of the first clamping assembly 810 is relatively simple and occupies less space.

[0227] For example, the first clamping drive device 811 and the second clamping drive device 812 may be cylinders.

[0228] Exemplarily, the transmission groove 817 is a linear slide groove inclined to both the left-right direction and the front-back direction, and the transmission pin 818 is arranged vertically.

[0229] In some examples, the second clamping assembly 820 can be configured similarly to the first clamping assembly 810. Specifically, the second clamping assembly 820 includes a third clamping drive device, a fourth clamping drive device, and a fifth clamping plate, a sixth clamping plate, a seventh clamping plate, and an eighth clamping plate connected end to end.

[0230] The fifth plywood and the seventh plywood are arranged opposite to each other, and the sixth plywood and the eighth plywood are arranged opposite to each other.

[0231] The fifth and sixth splints, the sixth and seventh splints, the seventh and eighth splints, and the eighth and fifth splints are all connected through a transmission groove 817 and a transmission pin 818 passing through the transmission groove 817, and the transmission pin 818 can slide along the transmission groove 817.

[0232] The output end of the third clamping drive device is connected to the fifth clamping plate, and the output end of the fourth clamping drive device is connected to the seventh clamping plate. The third clamping drive device and the fourth clamping drive device are used to drive the fifth clamping plate and the seventh clamping plate to move toward or away from each other, and drive the sixth clamping plate and the eighth clamping plate to move toward or away from each other synchronously through the transmission groove 817 and the transmission pin 818.

[0233] In this way, the third clamping drive device and the fourth clamping drive device can be driven to make the fifth clamping plate, the sixth clamping plate, the seventh clamping plate and the eighth clamping plate clamp the first pallet T1 from four sides, clamping the first pallet T1 firmly, and the structure of the second clamping assembly 820 is relatively simple and occupies less space.

[0234] Exemplarily, the third clamping drive device and the fourth clamping drive device may be cylinders.

[0235] Figure 18 This is a schematic diagram of a first hard disk moving mechanism and a second hard disk moving mechanism of a hard disk detection device provided in an embodiment of the present application.

[0236] like Figure 18 As shown, and see Figure 10 In some possible implementations, the first hard disk moving mechanism 200 includes a second linear conveying component 210 and a first lifting suction cup component 220 .

[0237] The second linear conveying assembly 210 is in transmission connection with the first lifting suction cup assembly 220 , and the second linear conveying assembly 210 is used to drive the first lifting suction cup assembly 220 to move left and right.

[0238] The first lifting suction cup assembly 220 is used to pick up the hard disk from the first tray T1 sent to the hard disk separation bin A2 when it moves above the hard disk separation bin A2. The first lifting suction cup assembly 220 is also used to place the hard disk into the hard disk detection module M1 when it moves above the hard disk detection module M1.

[0239] In this way, it is easy to automatically remove the hard disk from the first tray T1 sent to the hard disk separation compartment A2 and send it to the hard disk detection module M1.

[0240] Illustratively, the first lifting suction cup assembly 220 is used to place the hard disk onto the hard disk pushing mechanism 300 when it moves above the hard disk pushing mechanism 300 .

[0241] In some examples where the hard disk pushing mechanism 300 includes a hard disk receiving platform 320 , the first lifting suction cup assembly 220 is used to place the hard disk onto the hard disk receiving platform 320 when moving above the hard disk pushing mechanism 300 .

[0242] In some examples where the hard disk receiving platform 320 has a hard disk guide groove 321 , the first lifting suction cup assembly 220 is used to place the hard disk into the hard disk guide groove 321 when moving above the hard disk pushing mechanism 300 .

[0243] Exemplarily, the second linear conveying assembly 210 may include at least one of a linear motor, a belt transmission mechanism, a sprocket transmission mechanism, and the like.

[0244] For example, the first lifting suction cup assembly 220 can be used to suck up multiple hard disks and place the sucked hard disks into the hard disk detection module M1.

[0245] Figure 19 A schematic diagram of a first lifting suction cup assembly provided in an embodiment of the present application.

[0246] like Figure 19 As shown, the first lifting suction cup assembly 220 exemplarily includes a first lifting drive device 222 and a first suction cup assembly 221. The first lifting drive device 222 is vertically arranged. The second linear conveying assembly 210 is transmission-connected to the first lifting drive device 222. The second linear conveying assembly 210 is used to drive the first lifting drive device 222 to move left and right. The first suction cup assembly 221 is arranged at the lower end of the first lifting drive device 222. The first lifting drive device 222 is used to drive the first suction cup assembly 221 to move up and down. The first suction cup assembly 221 is used to absorb the hard disk.

[0247] Illustratively, the first lifting drive device 222 may be a cylinder.

[0248] Exemplarily, the first lifting suction cup assembly 220 also includes a first moving part, the first lifting drive device 222 is arranged on the first moving part, the second linear conveying assembly 210 is transmission-connected to the first moving part, and the second linear conveying assembly 210 is used to drive the first lifting drive device 222 to move left and right through the first moving part.

[0249] Illustratively, the first suction cup assembly 221 includes a plurality of first suction cup groups, each first suction cup group includes a plurality of first suction cups, and the plurality of first suction cups in each first suction cup group are used to adsorb a hard disk, so as to achieve stable adsorption of multiple hard disks.

[0250] In some possible implementations, the second pallet moving mechanism 700 includes a third linear conveying assembly, a second bearing assembly, a fourth lifting assembly, a fifth lifting assembly, and a sixth lifting assembly.

[0251] The third linear conveyor assembly is in transmission connection with the second load-bearing assembly and is used to drive the second load-bearing assembly back and forth. The fourth lifting assembly is located below the second material bin A4, the fifth lifting assembly is located below the hard drive loading bin A5, and the sixth lifting assembly is located below the second empty disk bin A6.

[0252] The sixth lifting assembly is used to take out the empty second tray T2 from the second empty tray magazine A6 and place the empty second tray T2 on the second carrying assembly.

[0253] The fifth lifting assembly is used to lift the empty second tray T2 from the second carrying assembly to the hard disk loading compartment A5, and is used to place the second tray T2 loaded with hard disks from the hard disk loading compartment A5 to the second carrying assembly after the hard disks are loaded into the second tray T2.

[0254] The fourth lifting assembly is used to lift the second tray T2 loaded with hard disks from the second carrying assembly to the second material bin A4. The second carrying assembly is used to drive the second tray T2 placed thereon to move forward and backward.

[0255] In this way, it is convenient to automatically take out the empty second tray T2 from the first empty tray bin A3 and send it to the hard disk loading bin A5 to load the hard disk that has been inspected, and after the hard disk is loaded into the second tray T2, the second tray T2 loaded with hard disk is sent from the hard disk loading bin A5 to the second material bin A4.

[0256] For example, the fourth, fifth, and sixth lifting assemblies are all elevating assemblies. When the sixth lifting assembly is raised, the empty second tray T2 in the second empty tray bin A6 can be dropped onto the sixth lifting assembly. When the fourth and fifth lifting assemblies are raised, they can lift the second tray T2. When the sixth and fifth lifting assemblies are lowered, they can place the second tray T2 onto the second supporting assembly.

[0257] Exemplarily, the fourth jacking assembly, the fifth jacking assembly and the sixth jacking assembly can all be vertically arranged cylinders.

[0258] In some possible implementations, the second material bin A4 is provided with a third clamping assembly 830 for clamping the side walls of the second tray T2 so that the second trays T2 loaded with hard disks can be stacked and stored in the second material bin A4.

[0259] After the fourth lifting component lifts the second tray T2 containing the hard disk to the second material bin A4, the third clamping component 830 clamps the second tray T2 lifted by the fourth lifting component to the second material bin A4, so that the second tray T2 containing the hard disk can be stacked and stored in the second material bin A4.

[0260] In this way, after the hard disks that have been inspected are loaded into the second tray T2, the second tray T2 loaded with the hard disks can be stored in the second material warehouse A4.

[0261] Exemplarily, the second trays T2 loaded with hard disks are stacked in the second material bin A4.

[0262] For example, when the fourth lifting assembly lifts the second pallet T2 containing the hard disk to the second material bin A4, the third clamping assembly 830 opens first, causing the second pallet T2 stored in the second material bin A4 to fall onto the second pallet T2 lifted by the fourth lifting assembly. The fourth lifting assembly causes the bottom-layer second pallet T2 lifted by it to rise to a position opposite to the third clamping assembly 830, and then causes the third clamping assembly 830 to clamp the bottom-layer second pallet T2 lifted by the fourth lifting assembly to store the second pallet T2 containing the hard disk in the second material bin A4.

[0263] In some possible implementations, the second empty tray bin A6 is provided with a fourth clamping assembly 840, which is used to clamp the side of the second tray T2.

[0264] After the sixth lifting assembly rises to the second pallet T2 at the bottom layer of the second empty disk bin A6, the fourth clamping assembly 840 is opened to allow the second pallet T2 stored in the second empty disk bin A6 to fall to the sixth lifting assembly, and the fourth clamping assembly 840 clamps the second pallet T2 located above the second pallet T2 at the bottom layer of the second empty disk bin A6, so that the sixth lifting assembly can take out the second pallet T2 at the bottom layer of the second empty disk bin A6.

[0265] In this way, it is easy to store the empty second tray T2 in the second empty tray magazine A6 and the sixth lifting assembly picks up the empty second tray T2 from the second empty tray magazine A6.

[0266] Exemplarily, the empty second trays T2 are stacked in the second empty tray magazine A6.

[0267] For example, after the sixth jacking assembly rises to the second pallet T2 at the bottom layer of the second empty disk bin A6, the fourth clamping assembly 840 opens, causing all the second pallets T2 stored in the second empty disk bin A6 to fall to the top surface of the sixth jacking assembly. Then, through the lifting and lowering of the sixth jacking assembly, the second pallet T2 on the second layer from bottom to top is made opposite to the fourth clamping assembly 840, and the fourth clamping assembly 840 clamps the second pallet T2 on the second layer from bottom to top. Then, the sixth jacking assembly is lowered, and the second pallet T2 on the bottom layer descends to the second supporting assembly along with the sixth jacking assembly.

[0268] In some possible embodiments, the third linear conveying assembly includes a third linear slide, a fourth linear slide, a second linear drive device and a second synchronization assembly. The third linear slide and the fourth linear slide are arranged side by side and at intervals. The third linear slide and the fourth linear slide both extend in the front-to-back direction.

[0269] The second bearing assembly includes a third bearing member and a fourth bearing member arranged side by side on the left and right, the third bearing member and the fourth bearing member are spaced apart on the left and right, the third bearing member is slidingly connected to the third linear slide rail, the fourth bearing member is slidingly connected to the fourth linear slide rail, the third bearing member and the fourth bearing member are transmission-connected through the second synchronization assembly, the second linear drive device is provided on the third linear slide rail, the output end of the second linear drive device is transmission-connected to the third bearing member, the second linear drive device is used to drive the third bearing member to move forward and backward, and drive the fourth bearing member to move forward and backward synchronously through the second synchronization assembly.

[0270] Along the left-right direction, the fourth lifting assembly, the fifth lifting assembly and the sixth lifting assembly are located between the third linear slide rail and the fourth linear slide rail, and between the third bearing member and the fourth bearing member.

[0271] The sixth lifting assembly is used to place the empty second tray T2 onto the third and fourth bearing members.

[0272] The fifth lifting assembly is used to place the second tray T2 loaded with hard disks from the hard disk loading compartment A5 to the third and fourth carriers after the hard disks are loaded into the second tray T2.

[0273] The third supporting member and the fourth supporting member are used to drive the second tray T2 placed thereon to move forward and backward.

[0274] In this way, the third linear conveyor assembly, through the third load-bearing assembly, drives the second pallet T2 back and forth, and the lifting and lowering of the second pallet T2 by the fourth, fifth, and sixth lifting assemblies are less likely to interfere with each other. This facilitates the coordinated removal of the empty second pallet T2 from the second empty disk bin A6 and its delivery to the hard disk loading bin A5 for loading hard disks, as well as the automatic delivery of the loaded second pallet T2 from the hard disk loading bin A5 to the second material bin A4 after the hard disks have been loaded into the second pallet T2. Furthermore, a single second linear drive device can simultaneously drive the third and fourth load-bearing members back and forth, resulting in better synchronization between the third and fourth load-bearing members and a relatively simple overall structure.

[0275] Exemplarily, the second linear drive device may be an electric cylinder.

[0276] Exemplarily, the third supporting member and the fourth supporting member are both strip-shaped members extending along the front-to-back direction.

[0277] Exemplarily, the second synchronization assembly includes a third belt mechanism, a fourth belt mechanism, a third synchronization rod and a fourth synchronization rod. The third belt mechanism and the fourth belt mechanism are arranged opposite to each other on the left and right. The third carrier is fixedly connected to the belt of the third belt mechanism. The fourth carrier is fixedly connected to the belt of the fourth belt mechanism. The front drive wheel of the third belt mechanism is coaxially fixed to the front drive wheel of the fourth belt mechanism through the third synchronization rod. The rear drive wheel of the fourth belt mechanism is coaxially fixed to the rear drive wheel of the fourth belt mechanism through the fourth synchronization rod.

[0278] In some possible implementations, the top surface of the second carrying assembly has a third tray placement position and a fourth tray placement position arranged front to back.

[0279] The third pallet placement position and the fourth pallet placement position are both provided with a second positioning structure, which is used to cooperate with the second matching structure on the bottom surface of the second pallet T2 to achieve positioning of the second pallet T2 and the second carrying assembly.

[0280] When the third tray is located below the second empty disk bin A6, the fourth tray is located below the hard disk loading bin A5. When the third tray is located below the hard disk loading bin A5, the fourth tray is located below the second material bin A4.

[0281] The sixth lifting assembly is used to place the empty second pallet T2 to the third pallet placement position when the third pallet placement position is located below the second empty pallet bin A6.

[0282] The fifth lifting assembly is used to lift the empty second tray T2 from the third tray placement position to the hard disk loading chamber A5 when the third tray placement position is located below the hard disk loading chamber A5, and is used to place the second tray T2 loaded with hard disks from the hard disk loading chamber A5 to the fourth tray placement position when the fourth tray placement position is located below the hard disk loading chamber A5.

[0283] The fourth lifting assembly is used to lift the second tray T2 loaded with hard disks from the fourth tray placement position to the second material bin A4 when the fourth tray placement position is located below the second material bin A4.

[0284] In this way, the fifth lifting assembly can be raised and lowered to shift the second pallet T2 between the third and fourth pallet placement positions. Driven by the second carrying assembly, the second pallet T2 can then be repositioned after moving a certain distance, thereby improving the positioning accuracy of the second pallet T2 and facilitating the automated movement of the second pallet T2. Furthermore, the coordination of the third linear conveying assembly, the fourth lifting assembly, the fifth lifting assembly, and the sixth lifting assembly allows the third and fourth pallet placement positions to operate simultaneously, thereby improving work efficiency.

[0285] Exemplarily, the third linear conveyor assembly drives the second bearing assembly to reciprocate in the front-to-back direction. When the third pallet placement position is located below the second empty disk bin A6, the sixth lifting assembly picks up an empty second pallet T2 from the second empty disk bin A6 and places the empty second pallet T2 in the third pallet placement position. The third linear conveyor assembly then drives the second bearing assembly to a position where the third pallet placement position is located below the hard disk loading bin A5 and the fourth pallet placement position is located below the second material bin A4. At this point, the fifth lifting assembly rises to lift the empty second pallet T2 from the third pallet placement position to the hard disk loading bin A5. After the empty second pallet T2 is lifted from the third pallet placement position by the fifth lifting assembly, the third linear conveyor assembly drives the second bearing assembly to move to a position where the third pallet placement position is located below the second empty disk bin A6 and the fourth pallet placement position is located below the hard disk loading bin A5. At this time, the sixth lifting assembly picks up the empty second pallet T2 from the second empty disk bin A6 again and places it in the third pallet placement position. The fifth lifting assembly places the second pallet T2 loaded with hard disks from the hard disk loading bin A5 to the fourth pallet placement position. Then, the third linear conveyor assembly drives the second bearing assembly to move to a position where the third pallet placement position is located below the hard disk loading bin A5 and the fourth pallet placement position is located below the second material bin A4. At this time, the fifth lifting assembly rises to lift the empty second pallet T2 from the third pallet placement position to the hard disk loading bin A5, and the fourth lifting assembly rises to lift the second pallet T2 loaded with hard disks from the fourth pallet placement position to the second material bin A4. In this way, the third tray placement position and the fourth tray placement position can work simultaneously, so that the hard disk detection device has higher working efficiency.

[0286] Illustratively, the second positioning structure includes a plurality of second positioning pins spaced apart, and the third and fourth carriers are each provided with a second positioning pin. The second mating structure includes second positioning holes provided on the bottom surface of the second tray T2, the second positioning holes being provided corresponding to the second positioning pins, and the second positioning pins being configured to be inserted into the corresponding second positioning holes.

[0287] In some possible implementations, a suction cup assembly 160 is provided on the top of the fourth jacking assembly, the fifth jacking assembly, and the sixth jacking assembly.

[0288] In this way, when the second pallet T2 is placed above the fourth, fifth, and sixth lifting assemblies, it is securely positioned and unlikely to shift. The second pallet T2 reaches each transfer position with high accuracy, facilitating automated movement of the second pallet T2. Furthermore, when the suction cup assembly 160, located above the sixth lifting assembly, picks up an empty second pallet T2 from the second empty pallet bin A6, it can pull the empty second pallet T2 out of the second empty pallet bin A6 by suctioning the bottom surface of the second pallet T2.

[0289] Exemplarily, the suction cup assembly 160 provided on the top of the fourth jacking assembly, the fifth jacking assembly and the sixth jacking assembly includes a plurality of suction cups distributed in an array to facilitate adsorption of multiple positions of the second pallet T2, so that the suction cup assembly 16 provided on the top of the fourth jacking assembly, the fifth jacking assembly and the sixth jacking assembly can adsorb the second pallet T2 more stably.

[0290] In some possible implementations, the third clamping assembly 830 includes a fifth clamping drive device, a sixth clamping drive device, and a ninth clamping plate, a tenth clamping plate, an eleventh clamping plate, and a twelfth clamping plate that are sequentially connected end to end.

[0291] The ninth plywood is arranged opposite to the eleventh plywood, and the tenth plywood is arranged opposite to the twelfth plywood.

[0292] The ninth and tenth splints, the tenth and eleventh splints, the eleventh and twelfth splints, and the twelfth and ninth splints are all connected through a transmission groove 817 and a transmission pin 818 passing through the transmission groove 817, and the transmission pin 818 can slide along the transmission groove 817.

[0293] The output end of the fifth clamping drive device is connected to the ninth clamping plate, and the output end of the sixth clamping drive device is connected to the eleventh clamping plate. The fifth clamping drive device and the sixth clamping drive device are used to drive the ninth clamping plate and the eleventh clamping plate to move toward or away from each other, and drive the tenth clamping plate and the twelfth clamping plate to move toward or away from each other synchronously through the transmission groove 817 and the transmission pin 818.

[0294] In this way, the ninth clamping plate, the tenth clamping plate, the eleventh clamping plate and the twelfth clamping plate can be driven by the fifth clamping drive device and the sixth clamping drive device to clamp the second pallet T2 from four sides, thereby firmly clamping the second pallet T2. In addition, the structure of the third clamping assembly 830 is relatively simple and occupies less space.

[0295] Exemplarily, the fifth clamping drive device and the sixth clamping drive device may be cylinders.

[0296] In some examples, the fourth clamping assembly 840 can be configured with reference to the third clamping assembly 830. Specifically, the fourth clamping assembly 840 includes a seventh clamping drive device, an eighth clamping drive device, and a thirteenth clamping plate, a fourteenth clamping plate, a fifteenth clamping plate, and a sixteenth clamping plate connected end to end.
