Technical Field

[0001] This invention relates to the field of contact testing equipment technology, specifically to a server hard drive bracket contact testing device. Background Technology

[0002] A hard drive bracket is a functional component used to fix and support hard drives. It is widely used in computer mainframes, servers, storage devices, and other scenarios. It is like a "safety seat" for hard drives, not only keeping them stable in the device but also assisting in functions such as heat dissipation and convenient installation. It is an important part of the internal structure of electronic devices. After the hard drive bracket is manufactured, it needs to be tested for continuity and resistance to ensure that the hard drive bracket is fully functional. The existing testing methods are all manual using testing equipment. This testing method is inefficient, and the long hours of repetitive manual work can easily lead to decreased attention and problems such as false positives and false negatives.

[0011] Preferably, the front of the detection host is equipped with an inkjet printer located on the side of each of the two detection components, and the inkjet printer is electrically connected to the detection host.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a server hard disk bracket contact detection device, which has the following beneficial effects: 1. By setting up a detection component and a stepping lifting component, the detection component has two parts, one for detecting continuity and the other for detecting resistance. The initial state of the stepping lifting component is downward, that is, the rotating arm is in a downward vertical state. When the feeding conveyor belt sends the hard disk rack onto the positioning component, the reduction motor drives the rotating arm to rotate 180 degrees counterclockwise through the rotating shaft. At this time, the rotating arm drives the positioning bracket to move upward through the lifting frame, and lifts the hard disk rack to the position of the detection component through the positioning component. At this time, the detection component detects the hard disk. Then the rotating component continues to rotate 180 degrees counterclockwise to reset. At the same time, the positioning bracket moves downward through the lifting frame, and lowers the hard disk rack through the discharge conveyor belt. This achieves the purpose of automatic feeding, detection, and unloading, which greatly improves the detection efficiency and ensures the consistency of the detection results.

[0013] 2. By setting up a lifting frame and a positioning bracket, the lifting frame is connected to the rotating arm on the same side to form a parallelogram structure. Utilizing the parallelogram's property of parallel opposite sides, the lifting frame is constrained, allowing it to reciprocate within the rotation range of the rotating arm under its drive. This, in turn, moves the positioning bracket at the top. There are two positioning brackets, and their movement paths intersect. During operation, the positioning bracket on one side of the feeding conveyor belt lifts the untested hard disk rack under the detection component for continuity testing, and then places it at the position where its path intersects with that of the positioning bracket on the other side. Meanwhile, the positioning bracket on the other side lifts the hard disk rack that has undergone continuity testing under the detection component for resistance testing, and then places it onto the discharge conveyor belt. This achieves the purpose of step-by-step feeding while simultaneously performing continuity and resistance testing. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-7 A server hard disk bracket contact detection device includes a base 1, a detection host 8 on the base 1, a display screen 9 on the detection host 8, detection components 7 on both sides of the display screen 9, a stepping lifting component 2 on the base 1 corresponding to the detection component 7, and a feeding conveyor belt 3 and a discharging conveyor belt 12 for transporting hard disk brackets 5 on both sides of the stepping lifting component 2 on the base 1. By setting up a detection component 7 and a stepping lifting component 2, the detection component 7 is equipped with two parts for detecting continuity and resistance respectively. The stepping lifting component 2 is initially in a downward state, that is, the rotating arm 203 is in a downward vertical state. When the feeding conveyor belt 3 sends the hard disk rack 5 onto the positioning component 6, the reduction motor 207 drives the rotating arm 203 to rotate 180 degrees counterclockwise through the rotating shaft 202. At this time, the rotating arm 203 drives the positioning bracket 205 to move upward through the lifting frame 204, and lifts the hard disk rack 5 to the position of the detection component 7 through the positioning component 6. At this time, the detection component 7 detects the hard disk. Then the rotating component continues to rotate 180 degrees counterclockwise to reset. At the same time, the positioning bracket 205 moves downward through the lifting frame 204, and lowers the hard disk rack 5 through the discharge conveyor belt 12. This achieves the purpose of automatic feeding, detection and unloading, which greatly improves the detection efficiency and ensures the consistency of the detection results.

[0018] The stepping lifting component 2 includes two support frames 201 mounted on the base 1. Each support frame 201 is equipped with a rotating shaft 202. A chain drive assembly 206 is provided between the two rotating shafts 202. A reduction motor 207 is connected to one of the rotating shafts 202. Rotating arms 203 are fixedly mounted at both ends of the rotating shaft 202. A lifting frame 204 is hinged to the end face of the adjacent rotating arms 203. Two positioning brackets 205 are provided at the top of the lifting frame 204. By setting up a lifting frame 204 and a positioning bracket 205, the lifting frame 204 is connected to the rotating arm 203 on the same side to form a parallelogram structure. The lifting frame 204 is constrained by the parallelism of opposite sides of the parallelogram, so that the lifting frame 204 moves back and forth within the rotation range of the rotating arm 203 under the drive of the rotating arm 203, and drives the positioning bracket 205 at the top to move. There are two positioning brackets 205, and their movement paths intersect. During operation, the positioning bracket 205 on one side of the feeding conveyor belt 3 will lift the untested hard disk rack 5 to the detection component 7 for continuity detection, and then place it at the position where it intersects with the path of the positioning bracket 205 on the other side. The positioning bracket 205 on the other side will lift the hard disk rack 5 that has passed continuity detection to the detection component 7 for resistance detection, and then place it on the discharge conveyor belt 12. This achieves the purpose of step feeding and continuity and resistance detection at the same time.

[0019] A positioning component 6 for positioning the hard disk frame 5 is provided on the base 1 within the lifting component. The positioning component 6 includes a connecting frame 601 on the base 1. The connecting frame 601 is provided with a starting positioning plate 602 near the feeding conveyor belt 3 and a transfer magnetic suction plate 605 located between the two detection components 7. The starting positioning plate 602 is provided with a positioning protrusion 604 that fits into the hard disk frame 5. A stop plate 603 is provided on the starting positioning plate 602 away from the feeding conveyor belt 3. A limit plate 606 is provided on the transfer magnetic suction plate 605 near both ends. By setting up a starting positioning plate 602 and a transfer magnetic suction plate 605, the starting positioning plate 602 is located at the end face of the feeding conveyor belt 3 and is consistent with the movement path of the positioning bracket 205. During operation, the hard disk rack 5 on the feeding conveyor belt 3 will be pushed onto the starting positioning plate 602 and engaged with the hard disk rack 5 by using the positioning protrusion 604, so that the position of the hard disk rack 5 overlaps with the movement path of the positioning bracket 205, making it easy for the positioning bracket 205 to lift it. The transfer magnetic suction plate 605 is located at the intersection of the movement paths of the two positioning brackets 205, so that the front positioning bracket 205 can place the hard disk rack 5 on the transfer magnetic suction plate 605, and then the rear positioning bracket 205 will lift it step by step.

[0020] The discharge conveyor belt 12 is equipped with an inclined slide 11 at one end of the lifting component, and the inclined slide 11 is located within the movement path of the positioning bracket 205; By setting up the inclined slide 11, which is located inside the step lifting component 2 and tilted towards the discharge conveyor belt 12, the step lifting component 2 can avoid the inclined slide 11 on the outside during operation. The hard disk rack 5 located on the step lifting component 2 will be lifted by the inclined slide 11, separating it from the step lifting component 2, and then sliding along the inclined slide 11 onto the discharge conveyor belt 12 to achieve the purpose of automatic material unloading.

[0021] The feeding conveyor belt 3 is equipped with a pushing component 4 that is hinged to the end face of the rotating arm 203. The pushing component 4 is used to feed a single hard disk rack 5 into the starting positioning plate 602. By setting up a pushing component 4, the pushing component 4 can be linked with the rotating arm 203. When the rotating component rotates counterclockwise, it will pull the pushing component 4 to move, so that the pushing component 4 drives the hard disk rack 5 on the feeding conveyor belt 3 into the positioning component 6, so as to achieve the purpose of single feeding and prevent multiple hard disk racks 5 from piling up and affecting the feeding and lifting work.

[0022] The pushing component 4 includes slide rails 401 on both sides of the feeding conveyor belt 3, a pushing frame 402 slidably mounted on the slide rails 401, a steel cable 403 hinged to the rotating arm 203 at the bottom end of the pushing frame 402, a movable shaft 404 on the side of the pushing frame 402, a tension spring 405 on the movable shaft 404, and a fixed shaft 406 fixed to the side of the feeding conveyor belt 3 at the other end of the tension spring 405. By setting up a steel cable 403 and a tension spring 405, when the rotating arm 203 rotates, it will drive the steel cable 403, causing the steel cable 403 to pull the pusher frame 402, which will move along the slide rail 401. The pusher frame 402 is used to actively push a single hard disk rack 5 forward, and the pushing speed is greater than the speed of the feeding conveyor belt 3, so that the frontmost hard disk rack 5 can be separated from the following ones to prevent material accumulation. The tension spring 405 can use its own elasticity to pull the pusher frame 402 back to its original position after the steel cable 403 is depressurized, so that the pusher frame 402 can move back and forth.

[0023] The front end of the pusher 402 is provided with a push plate 407, and the top end of the pusher 402 is provided with a hinge 408 connected to the push plate 407. The push plate 407 can rotate clockwise along the axis of the hinge 408, but cannot rotate counterclockwise. By setting the hinge 408, when the pusher 402 moves towards the positioning component 6, the pusher plate 407 will fit against the inner side of the hard disk frame 5. At this time, the hard disk frame 5 applies a counterclockwise rotational reaction force to the pusher plate 407. However, due to the restriction of the pusher 402, the pusher plate 407 cannot rotate counterclockwise. Therefore, the hard disk frame 5 will move with the pusher 402 and be pushed onto the positioning component 6. When the hard disk frame 5 is reset, the pusher plate 407 is located on the outer side of the hard disk frame 5. The hard disk frame 5 applies a clockwise reaction force to the pusher plate 407, causing the pusher plate 407 to rotate upward to avoid the hard disk frame 5 and fall into the inner side of the hard disk frame 5, which facilitates subsequent pushing. The above structure achieves the effect of unidirectional feeding.

[0024] The detection component 7 includes a fixed frame 701 connected to the detection host 8. A cylinder 702 is provided on the end face of the fixed frame 701. A rack 703 is provided on the output end of the cylinder 702. Gears 704 that are rotatably connected to the fixed frame 701 are meshed on both sides of the rack 703. A detection main board 705 is provided on the side of each of the two gears 704. A detection contact rod 706 that is attached to the hard disk frame 5 is provided under the detection main board 705. A detection wire 707 that is connected to the detection host 8 is provided on the detection main board 705. When performing testing, the cylinder 702 drives the rack 703 to move upward, and the rack 703 drives the meshing gear 704 on both sides to rotate. The gear 704 then drives the detection contact rod 706 to rotate downward through the detection motherboard 705 and clamp it on the contacts at both ends of the hard disk frame 5. Subsequently, the detection host 8 performs continuity and resistance testing on the hard disk frame 5 through the detection wire 707. After the test is completed, the cylinder 702 drives the rack 703 to move downward, so that the gear 704 drives the detection motherboard 705 and the detection contact rod 706 to unfold, so that it will not affect the movement of the stepper lifting component 2.

[0025] The front of the detection host 8 is equipped with inkjet printers 10 located on the sides of the two detection components 7, and the inkjet printers 10 are electrically connected to the detection host 8. By setting up an inkjet printer 10, which is electrically connected to the detection host 8, when the hard disk rack 5 passes the detection, the inkjet printer 10 will spray a pass mark on the hard disk rack 5. For hard disk racks 5 that fail the detection, no mark will be sprayed, so that the detected hard disk racks 5 can be distinguished, which is convenient for subsequent maintenance or scrapping.

[0026] Working principle: During operation, the feeding conveyor belt 3 moves the hard disk rack 5 onto the positioning component 6. The stepping lifting component 2 lifts the hard disk rack 5 on the positioning component 6 to the position of the detection component 7. After passing the inspection, it is marked by the inkjet printer 10. Finally, the hard disk rack 5 that has completed the inspection is dropped onto the discharge conveyor belt 12 by the inclined slide 11 and sent out. At the same time as the stepping lifting component 2 is working, the push component 4 linked with it will send the hard disk rack 5 at the front end of the feeding conveyor belt 3 onto the positioning component 6 separately, so as to achieve the purpose of automatic feeding, inspection and unloading.

[0027] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
