Description

Technical Field

[0001] The present invention belongs to the technical field of solid-state hard disk quality inspection, and in particular is a test platform for solid-state hard disk quality inspection. Background Art

[0002] Solid-state drive, also known as solid-state drive, is a hard disk made of solid-state electronic storage chip array. There are two types of storage media for solid-state drives: one uses flash memory (FLASH chip) as the storage medium, and the other uses DRAM as the storage medium.

[0003] At present, when producing solid-state hard disk circuit boards, it is necessary to divide the entire circuit board into several single primary circuit boards, and then package the primary circuit boards into a shell. During the hard disk circuit board dividing process, the circuit board is easily warped due to the influence of the dividing stress, and the warped circuit board is difficult to be smoothly installed into the shell. Even if it can be smoothly installed into the shell, the chips and components on the warped circuit board are easily damaged. Therefore, it is necessary to test the flatness of the circuit board after the circuit board is divided. In the existing technology, the means for detecting the flatness of the circuit board mostly uses a leveling column to move along the surface of the circuit board. When the flatness of the circuit board does not meet the requirements, the leveling column retracts to cause the pressure sensor value to change, thereby controlling the indicator light to turn on and off to complete the circuit board flatness detection. This detection method is relatively traditional. On the one hand, it cannot realize large-scale automatic detection of circuit boards. On the other hand, when the leveling column detects that the flatness of the circuit board does not meet the requirements, the circuit board cannot be automatically rejected, and manual rejection operation is required, which affects the detection efficiency.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0044] Please refer to Figure 1 and Figure 2The present embodiment provides a test platform for solid-state hard disk quality inspection, including a bracket 10, a first drive assembly 20, an adsorption box 30, a second drive assembly 40, an exhaust assembly 50, and a conveyor belt 70. The conveyor belt 70 is installed on the bracket 10 and is used to convey a plurality of hard disk circuit boards to be inspected. A top plate 102 is fixedly provided on the upper portion of the bracket 10 through a plurality of vertical rods 101. The top plate 102 is arranged above the conveyor belt 70. The adsorption box 30 is arranged between the top plate 102 and the conveyor belt 70. The first drive assembly 20 is installed at the bottom of the top plate 102 and is used to drive the adsorption box 30 to move up and down. The exhaust assembly 50 is installed on the side wall of the adsorption box 30. When the adsorption box 30 moves downward and contacts the hard disk circuit board, the exhaust assembly 50 is used to exhaust the adsorption box 30. The second drive assembly 40 is arranged on the side of the adsorption box 30. When the adsorption box 30 moves upward, the second drive assembly 40 is used to drive the adsorption box 30 to rotate.

[0045] When it is necessary to test the straightness of several hard disk circuit boards, several hard disk circuit boards to be tested can be placed on the upper part of the conveyor belt 70, and the conveyor belt 70 conveys the several hard disk circuit boards in sequence, so that the several hard disk circuit boards are moved to the position below the adsorption box 30 in sequence. When a group of hard disk circuit boards moves to the position below the adsorption box 30, the first driving component 20 drives the adsorption box 30 to move downward so that the bottom of the adsorption box 30 contacts the hard disk circuit board, and then the exhaust component 50 performs exhaust processing on the inside of the adsorption box 30, and then the first driving component 20 drives the adsorption box 30 to move upward. After the adsorption box 30 moves up a certain distance, the second driving component 40 drives the adsorption box 30 to rotate; when the exhaust component 50 is exhausting the inside of the adsorption box 30, if the bottom of the adsorption box 30 If the straightness of the hard disk circuit board meets the requirements, the bottom of the adsorption box 30 can be in full contact with the hard disk circuit board. When the vacuum component 50 vacuums the inside of the adsorption box 30, the hard disk circuit board can be adsorbed to the bottom of the adsorption box 30, and then moves up synchronously with the adsorption box 30, and in the subsequent rotation process of the adsorption box 30, the hard disk circuit board rotates from the bottom position of the adsorption box 30 to the side position. On the contrary, if the straightness of the hard disk circuit board at the bottom of the adsorption box 30 does not meet the requirements, it indicates that there is warping in this group of hard disk circuit boards, and the hard disk circuit board cannot be in full contact with the bottom wall of the adsorption box 30, so that when the vacuum component 50 vacuums the inside of the adsorption box 30, the hard disk circuit board cannot be adsorbed to the bottom of the adsorption box 30, and then cannot be taken away from the conveyor belt 70 when the adsorption box 30 moves up, and is thus continued to be transported by the conveyor belt 70.

[0046] See also Figure 1 as well as Figure 4In one embodiment, a first support shaft 302 is fixedly provided on the side wall of the adsorption box 30, and the first driving assembly 20 includes a hydraulic cylinder 201 and a U-shaped plate 202. The hydraulic cylinder 201 is fixedly provided at the bottom of the top plate 102, and the U-shaped plate 202 is installed at the output end of the hydraulic cylinder 201. The opening of the U-shaped plate 202 is set downward, and the adsorption box 30 is set on the inner side of the U-shaped plate 202. The first support shaft 302 passes through the U-shaped plate 202 and rotates with the U-shaped plate 202.

[0047] When a group of hard disk circuit boards moves to the bottom of the adsorption box 30, the hydraulic cylinder 201 extends and drives the U-shaped plate 202 to move downward. The U-shaped plate 202 drives the adsorption box 30 to move downward, so that the bottom of the adsorption box 30 contacts the group of hard disk circuit boards. Then the vacuum assembly 50 vacuums the inside of the adsorption box 30, and then the hydraulic cylinder 201 drives the U-shaped plate 202 to move upward, thereby driving the adsorption box 30 to move up. After the adsorption box 30 moves up a certain distance, the second drive assembly 40 drives the adsorption box 30 to rotate. During this process, if the straightness of the hard disk circuit board meets the requirements, the hard disk circuit board can follow the adsorption box 30 and rotate synchronously. On the contrary, if the hard disk circuit board is warped, the hard disk circuit board cannot be adsorbed by the adsorption box 30 and is trapped on the upper part of the conveyor belt 70. The hard disk circuit board is continued to be transported by the conveyor belt 70.

[0048] See also Figure 4 In one embodiment, the second driving assembly 40 includes a first support rod 401, a second support rod 402, a first rack 403 and a first gear 404, the first support rod 401 is arranged on the side of the adsorption box 30, the top of the first support rod 401 is fixedly connected to the bottom wall of the top plate 102, the second support rod 402 is fixedly set on one side of the first support rod 401, the first rack 403 is fixedly set on the side wall of the second support rod 402, and the first gear 404 is fixedly set on the outside of the first support shaft 302 and can engage with the first rack 403.

[0049] When the hydraulic cylinder 201 drives the U-shaped plate 202 to move upward and then drives the adsorption box 30 to move up a certain distance, the first gear 404 outside the first support shaft 302 and the first rack 403 enter into a meshing state, and the first rack 403 drives the first gear 404 to rotate, thereby driving the first support shaft 302 and the adsorption box 30 to rotate. At this time, if a hard disk circuit board is adsorbed on the bottom of the adsorption box 30, the hard disk circuit board rotates synchronously with the adsorption box 30, and thus rotates to the side of the conveyor belt 70.

[0050] See also Figure 3 、 Figure 5 as well as Figure 7In one embodiment, a plurality of adsorption holes 301 are provided on the bottom wall of the adsorption box 30, a slide groove 303 is provided on the side wall of the adsorption box 30, and the air extraction component 50 includes a second rack 501, a connecting rod 502, a second gear 503, a support 504, a piston plate 505 and a first elastic member 506. The support 504 is fixedly arranged on the outer wall of the adsorption box 30, the second gear 503 is rotatably arranged on one side of the support 504, the second rack 501 is meshed and arranged on one side of the second gear 503, the piston plate 505 is movably arranged inside the adsorption box 30, and one end of the connecting rod 502 is fixed to the second rack 501. The first support rod 401 is connected to the first support rod 401, and the other end extends from the slide groove 303 to the interior of the adsorption box 30 and is fixedly connected to the piston plate 505. One end of the first elastic member 506 is connected to the inner top wall of the adsorption box 30, and the other end is connected to the piston plate 505, which is used to provide elastic tension to the piston plate 505. A plurality of bevel gear pieces 405 are hingedly provided on the side wall of the first support rod 401, and the plurality of bevel gear pieces 405 can be unidirectionally meshed with the second gear 503. One side of each group of bevel gear pieces 405 is connected to the first support rod 401 through a group of third elastic members (not shown in the figure), and the third elastic member is used to provide elastic support to the bevel gear pieces 405.

[0051] When the hydraulic cylinder 201 drives the adsorption box 30 to move downward, the adsorption box 30 drives the first gear 404, the support 504, the second gear 503, the second rack 501 and the piston plate 505 to move downward synchronously. When the second gear 503 moves downward, it meshes with the several bevel gear pieces 405. The several bevel gear pieces 405 drive the second gear 503 to rotate. Through the meshing action of the second gear 503 and the second rack 501, the second rack 501 is driven to move downward along the outside of the adsorption box 30. The second rack 501 drives the piston plate 505 through the connecting rod 502, so that the piston plate 505 moves downward along the inside of the adsorption box 30. The first elastic member 506 is stretched by the force. After the bottom of the adsorption box 30 contacts the hard disk circuit board, the second gear 503 is disengaged from the several bevel gear pieces 405. The first elastic member 506 pulls the piston plate 505 so that the piston plate 505 moves upward along the inside of the adsorption box 30. At this time, if the hard disk circuit board meets the straightness requirements, the hard disk circuit board When the piston plate 505 moves upward, the hydraulic cylinder 201 drives the adsorption box 30 to move upward, thereby driving the first gear 404, the support 504, the second gear 503, the second rack 501 and the piston plate 505 to move upward synchronously. When the second gear 503 moves upward, it pushes the several bevel gear pieces 405 and drives the several bevel gear pieces 405 to deflect toward the first support rod 401 in turn. The several bevel gear pieces 405 cannot mesh with the second gear 503. After the adsorption box 30 moves up a certain distance, the first gear 404 meshes with the first rack 403, thereby driving the adsorption box 30 to rotate.

[0052] See also Figure 1 as well as Figure 6 In one embodiment, an air hole 306 is opened on the side wall of the adsorption box 30, and the air hole 306 is located below the piston plate 505. A sealing assembly 60 is also rotatably provided on the outer wall of the adsorption box 30. When the first elastic member 506 pulls the piston plate 505 to move upward along the inside of the adsorption box 30, the sealing assembly 60 is used to seal the air hole 306, so that the hard disk circuit board that meets the straightness requirement can be smoothly adsorbed to the bottom of the adsorption box 30. When the first gear 404 is engaged with the first rack 403, so that the bottom wall of the adsorption box 30 rotates to face the side of the conveyor belt 70, the sealing assembly 60 rotates to release the sealing state of the air hole 306. At this time, the area below the piston plate 505 on the inner side of the adsorption box 30 is communicated with the external environment through the opened air hole 306, and the hard disk circuit board on the bottom wall of the adsorption box 30 can no longer maintain the adsorption state and falls from the side of the conveyor belt 70.

[0053] In one embodiment, a receiving box (not shown in the figure) is further provided on the outside of the bracket 10. Through the setting of the receiving box, the hard disk circuit boards that fall from the side of the conveyor belt 70 can be received, thereby realizing the collection and storage of hard disk circuit boards that meet the flatness requirements.

[0054] See also Figure 1 as well as Figure 6 In one embodiment, a push rod 103 is fixedly provided on the side wall of the vertical pole 101, and the sealing assembly 60 includes a second support shaft 601 and a sealing plate 602. The second support shaft 601 is fixedly installed on the outer wall of the adsorption box 30, and the sealing plate 602 is rotatably provided outside the second support shaft 601 and is attached to the outer wall of the adsorption box 30.

[0055] When the first elastic member 506 pulls the piston plate 505 so that the piston plate 505 moves upward along the inside of the adsorption box 30, the sealing plate 602 is attached to the outer wall of the adsorption box 30 and seals the air hole 306. The upward movement of the piston plate 505 can adsorb the hard disk circuit board that meets the straightness requirements to the bottom of the adsorption box 30; after the adsorption box 30 moves up a certain distance, the first gear 404 engages with the first rack 403 to drive the adsorption box 30 to rotate, and the adsorption box 30 drives the second support shaft 601 and the sealing plate 602 to rotate. Plate 602 rotates synchronously. When the bottom wall of the adsorption box 30 rotates to a position toward the side of the conveyor belt 70, the push rod 103 can act on the sealing plate 602 and then push the sealing plate 602 so that the sealing plate 602 rotates relative to the second support shaft 601. The sealing plate 602 moves away from the outside of the air hole 306 to release the sealing state of the air hole 306. At this time, the negative pressure adsorption effect of the hard disk circuit board whose flatness meets the requirements is released, and the hard disk circuit board detaches from the bottom wall of the adsorption box 30 and falls from the side of the conveyor belt 70.

[0056] See also Figure 6 In one embodiment, a support block 305 is fixedly provided on the outer wall of the adsorption box 30 , and one side of the sealing plate 602 is connected to the support block 305 through a second elastic member 603 , and the second elastic member 603 is used to provide elastic support for the sealing plate 602 .

[0057] When the push rod 103 acts on the sealing plate 602 to drive the sealing plate 602 to rotate relative to the second support shaft 601 to open the air hole 306, the second elastic member 603 is compressed under force, and after the hard disk circuit board (if any) on the bottom wall of the adsorption box 30 falls and meets the requirements of flatness, the hydraulic cylinder 201 drives the U-shaped plate 202 to move downward again, thereby driving the adsorption box 30 to move downward again, the first gear 404 and the first rack 403 are reversely engaged, thereby driving the adsorption box 30 to rotate reversely, until the bottom wall of the adsorption box 30 is rotated to be downward, the first gear 404 and the first rack 403 are disengaged, the adsorption box 30 continues to adsorb and detect the subsequent hard disk circuit board, when the adsorption box 30 reversely rotates, the sealing plate 602 is separated from the push rod 103, the second elastic member 603 pushes the sealing plate 602 to make the sealing plate 602 reversely rotate relative to the second support shaft 601, and the sealing plate 602 reseals the air hole 306.

[0058] Please refer to Figure 6 In one embodiment, the adsorption box 30 is further provided with a limiting block 304 on the outer wall, when the sealing plate 602 seals the air hole 306, the sealing plate 602 can be pressed to one side of the limiting block 304 by the elastic support of the second elastic member 603 on the sealing plate 602, and the limiting block 304 limits the sealing plate 602, so that the sealing plate 602 can accurately seal the air hole 306.

[0059] In one embodiment, the first elastic member 506, the second elastic member 603 and the third elastic member can be springs or metal springs, which are not limited here.

[0060] In one embodiment, the conveying belt 70 is intermittent, when a group of hard disk circuit boards are conveyed to the position below the adsorption box 30, the conveying belt 70 stops running, and the hard disk circuit board is stationary below the adsorption box 30, when the hard disk circuit board completes the flatness detection, the conveying belt 70 continues to run to convey the subsequent hard disk circuit board to the position below the adsorption box 30.

[0061] The working principle of the present application is as follows:

[0062] When the hard disk circuit boards are inspected, they are placed on the upper part of the conveyor belt 70, and the conveyor belt 70 conveys the hard disk circuit boards. When a group of hard disk circuit boards moves to the bottom of the adsorption box 30, the hydraulic cylinder 201 extends and drives the U-shaped plate 202 and the adsorption box 30 to move downward. When the adsorption box 30 moves downward, the second gear 503 on its outer side engages with the several bevel gear pieces 405, thereby driving the second rack 501 to move downward. The second rack 501 drives the piston plate 505 to move downward along the inside of the adsorption box 30 through the connecting rod 502. When the bottom of the adsorption box 30 contacts the hard disk circuit board, the second gear 503 and the several bevel gear pieces 405 are disengaged, and the first elastic member 506 pulls the piston plate 505 to move upward along the inside of the adsorption box 30. At this time, if the straightness of the hard disk circuit board meets the requirements, the hard disk circuit board can be adsorbed to the bottom of the adsorption box 30. On the contrary, if the hard disk circuit board is warped, Then the hard disk circuit board cannot be adsorbed to the bottom of the adsorption box 30 and continues to stay on the upper part of the conveyor belt 70, and is then continued to be transported by the conveyor belt 70; when the piston plate 505 moves up along the inside of the adsorption box 30, the hydraulic cylinder 201 drives the U-shaped plate 202 and the adsorption box 30 to move up. At this time, the second gear 503 cannot engage with the several bevel gear pieces 405. When the adsorption box 30 moves up a certain distance, the first gear 404 on the outside of the adsorption box 30 engages with the first rack 403, thereby driving the adsorption box 30 to rotate compared to the U-shaped plate 202, and the adsorption box 30 transfers the hard disk circuit board (if any) adsorbed on its bottom to the outside of the conveyor belt 70, and then the push rod 103 pushes the sealing plate 602 so that the sealing plate 602 rotates compared to the second support shaft 601 to open the air hole 306, thereby releasing the adsorption state of the hard disk circuit board. After the hard disk circuit board is released from the side of the conveyor belt 70, it falls.

[0063] In the embodiment of the present invention, when it is necessary to test the straightness of several hard disk circuit boards, several hard disk circuit boards to be tested can be placed on the upper part of the conveyor belt 70, and the conveyor belt 70 conveys the several hard disk circuit boards in sequence, so that the several hard disk circuit boards are moved to the position below the adsorption box 30 in sequence. When a group of hard disk circuit boards moves to the position below the adsorption box 30, the first driving component 20 drives the adsorption box 30 to move downward so that the bottom of the adsorption box 30 contacts the hard disk circuit board, and then the exhaust component 50 performs exhaust treatment on the inside of the adsorption box 30, and then the first driving component 20 drives the adsorption box 30 to move upward. After the adsorption box 30 moves up a certain distance, the second driving component 40 drives the adsorption box 30 to rotate; when the exhaust component 50 performs exhaust treatment on the inside of the adsorption box 30, if the straightness of the hard disk circuit board at the bottom of the adsorption box 30 meets the requirement, the bottom of the adsorption box 30 can fully contact the hard disk circuit board. When the suction component 50 sucks air from the inside of the adsorption box 30, the hard disk circuit board can be sucked to the bottom of the adsorption box 30, and then moves up synchronously with the adsorption box 30, and in the subsequent rotation process of the adsorption box 30, the hard disk circuit board rotates from the bottom position of the adsorption box 30 to the side position. On the contrary, if the flatness of the hard disk circuit board at the bottom of the adsorption box 30 does not meet the requirements, it indicates that the group of hard disk circuit boards is warped, and the hard disk circuit board cannot fully contact the bottom wall of the adsorption box 30, so that when the suction component 50 sucks air from the inside of the adsorption box 30, the hard disk circuit board cannot be sucked to the bottom of the adsorption box 30, and then cannot be taken away from the conveyor belt 70 when the adsorption box 30 moves up, and is thus continued to be conveyed by the conveyor belt 70. Compared with the existing technology, it can not only realize automatic and continuous detection of the flatness of several hard disk circuit boards, but also automatically remove hard disk circuit boards with warping, which has the advantages of good detection effect and high detection efficiency.

[0064] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
