Description

Technical Field

[0002] A hard disk bracket is a device used to fix and install a hard disk. It can help users install a 2.5-inch hard disk into a chassis or server originally designed for a 3.5-inch hard disk. This bracket is usually made of plastic or metal, has a certain degree of elasticity and durability, can adapt to hard disks of different thicknesses, and ensures that the hard disk is stable and immovable through screws or other fixing methods. The hard disk bracket has multiple sides, and when installing the hard disk bracket, it is necessary to lock the screw holes on each side. However, due to the limitations of the hard disk bracket's own structure and the limitations of the screw locking mechanism, it is impossible to lock the screw holes on different sides of the hard disk bracket at the same time. Instead, different screw holes are locked in multiple steps. During this locking process, the hard disk bracket is fixed on the fixture. When multiple screw locking mechanisms lock the screw holes on different sides from different directions, the structure of the screw locking mechanism will be too complicated, which is not conducive to cost saving.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 As shown, the automatic screw locking device of the hard disk bracket provided in the embodiment of the present application comprises a frame 1, a turntable 2 arranged on the frame 1, a fixed plate 3 concentric with the turntable 2, a divider arranged on the frame 1 for driving the turntable 2 to rotate, and a plurality of jigs 4 circumferentially arranged on the turntable 2, and also comprises a loading station arranged on the frame 1 along the circumference of the turntable 2, a first screw locking mechanism 5, a first flipping mechanism 7, a second screw locking mechanism 6, a second flipping mechanism 8, a third screw locking mechanism 9, a unloading mechanism 11 and a reset mechanism 10, and the fixed plate 3 is provided with three pulling mechanisms 12 corresponding to the first flipping mechanism 7, the second flipping mechanism 8 and the reset mechanism 10, respectively.

[0033] In actual use, the hard disk bracket 100 is placed on the jig 4 at the loading station, and then the indexer drives the turntable 2 to rotate at an indexing rate. When the jig 4 passes through the first screw locking mechanism 5, the first screw hole of the hard disk bracket 100 is screwed by the first screw locking mechanism 5, and then the jig 4 moves to the corresponding position of the first flipping mechanism 7, and the jig 4 is pulled by the pulling mechanism 12, and then the jig 4 is flipped by the first flipping mechanism 7, and then the pulling mechanism 12 and the first flipping mechanism 7 are reset, and then the jig 4 is rotated to the second screw locking mechanism 6, and the hard disk bracket is screwed by the second screw locking mechanism 6. The second screw hole of 100 is screwed, and then the jig 4 is rotated to the second flipping mechanism 8. The pulling mechanism 12 pulls the jig 4 to make the product rotate, and then the second flipping mechanism 8 and the pulling mechanism 12 are reset; then the jig 4 is rotated with the turntable 2 to the third screw locking mechanism 9, and the No. 3 screw hole of the product is screwed by the third screw locking mechanism 9; then the jig 4 is rotated with the turntable 2 to the unloading mechanism 11, and the hard disk bracket 100 is taken out of the jig 4 by the unloading mechanism 11; then the jig 4 with the hard disk bracket 100 removed is rotated with the turntable 2 to the resetting mechanism 10, and is reset by the resetting mechanism 10.

[0034] In the above design, by setting the fixture 4 as a rotating structure, when screwing in the hard disk bracket 100 with multiple holes, the structures of the screw locking mechanisms corresponding to the various hole positions can be consistent, which effectively saves space and reduces the complexity of each screw locking mechanism.

[0035] Specifically: Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fixture 4 includes a No. 1 seat 41 fixedly arranged on the frame 1, a number of No. 1 guide pillars 42 extending in the radial direction of the frame 1 and slidably connected to the No. 1 seat 41, a No. 1 connecting block 43 connecting the No. 1 guide pillars 42 away from one end of the outer edge of the turntable 2, a No. 1 rotating shaft 44 extending in the radial direction and rotatably connected to the No. 1 seat 41, a rotating material unloading frame 45 fixedly connected to the No. 1 rotating shaft 44, a No. 1 spring 46 sleeved on the No. 1 guide pillar 42 and located in the No. 1 seat 41, and a limit convex 46 fixedly connected to the No. 1 guide pillar 42 and located in the installation box. A stopper 47, a stopper 48 and an elastic pressing piece 49 are arranged on the end surface of the rotating material discharge rack 45 away from the turntable 2. The rotating material discharge rack 45 is provided with a plurality of groups of grooves 401 plugged with the No. 1 guide column 42. The No. 1 spring 46 is close to one end of the rotating material discharge rack 45 and abuts against the limiting protrusion 47, and the other end of the No. 1 spring 46 abuts against the No. 1 seat 41. The side of the rotating material discharge rack 45 is provided with a positioning hole 402 for positioning the first flip mechanism 7, the second flip mechanism 8 and the reset mechanism 10, and a material discharge groove for placing the hard disk bracket 100.

[0036] In actual use, the hard disk bracket 100 is placed on the rotating material discharging rack 45, and the product is fixed by the elastic pressing piece 49. When the rotating material discharging rack 45 needs to be rotated, the pulling mechanism 12 pulls the No. 1 connecting block 43 toward the center of the turntable 2, so that the No. 1 spring 46 is compressed and the No. 1 guide column 42 is disengaged from the corresponding groove 401, and then the first flip mechanism 7 or the second flip mechanism 8 or the reset mechanism 10 drives the rotating material discharging rack 45 to rotate a predetermined angle around the No. 1 rotating shaft 44 and then disengage, and the first flip mechanism 7 or the second flip mechanism 8 or the reset mechanism 10 is reset, so that the other groove 401 cooperates with the No. 1 guide column 42 to realize the rotation of the rotating material discharging rack 45.

[0037] In the above design, the structural design and specific implementation of the fixture 4 can effectively cooperate with the pulling mechanism 12 and various flipping mechanisms to realize the rotation of the hard disk bracket 100.

[0038] Specifically: Figure 4 As shown, the No. 1 seat 41 is provided with a No. 1 through hole 411 slidably connected to the No. 1 guide column 42 and a No. 2 through hole 412 for installing the No. 1 rotating shaft 44, and the No. 1 through hole 411 is provided with a No. 1 linear bearing 413, and the No. 1 guide column 42 passes through the No. 1 linear bearing 413 and the No. 2 linear bearing 413 and is slidably connected, and the other end of the No. 1 spring 46 is against the rear side plate.

[0039] In actual use, when the No. 1 connecting block 43 is pulled by the pulling mechanism 12, the No. 1 guide column 42 follows the No. 1 connecting block 43 and slides along the linear bearing 413. The two ends of the No. 1 spring 46 are respectively against the limiting protrusion 47 and the No. 1 linear bearing 413.

[0040] In the above design, the structural design and specific implementation of the No. 1 seat 41 can effectively guide the No. 1 guide column 42 .

[0041] Specifically: Figure 1 and Figure 7 As shown, the pulling mechanism 12 includes a No. 3 cylinder 121 which is arranged on the fixed disk 3 in the radial direction and the output end faces the side of the fixture 4, and a block 122 fixedly arranged at the output end of the No. 3 cylinder 121, and the block 122 is provided with a slot 220, and the slot 220 includes a lateral opening for the No. 1 connecting block 43 to enter the slot 220, a lateral outlet for the No. 1 connecting block 43 to flow out of the slot 220, and a lower opening for avoiding the No. 1 connecting block 43.

[0042] In actual use, the jig 4 rotates with the turntable 2, so that the No. 1 connection block 43 enters the slot 220 from the side opening, and the No. 3 cylinder 121 drives the block 122 to move toward the center of the turntable 2, so that the inner wall of the slot 220 contacts the No. 1 connection block 43 and pulls the No. 1 connection block 43 to move synchronously. When the rotating material unloading rack 45 rotates completely, the No. 3 cylinder 121 is reset, so that the No. 1 connection block 43 is reset, so that the No. 1 guide column 42 cooperates with the corresponding groove 401, and then the jig 4 rotates with the turntable 2 and flows out of the slot 220 along the side outlet.

[0043] In the above design, the structural design and specific implementation method of the pulling mechanism 12 can effectively pull out the No. 1 block 491 of the fixture 4.

[0044] Specifically: Figure 4 and Figure 6 As shown, the elastic pressing member 49 includes a block No. 191 fixedly set on the rotating discharge rack 45 and provided with a vertical groove, a No. 2 spring 492 vertically set in the vertical groove, a clamping block 493 abutting against the lower end of the No. 2 spring 492 and slidably connected to the vertical groove, and a limit pin 494 connecting the clamping block 493 and the block No. 191, the clamping block 493 is provided with a vertically extending No. 1 waist-shaped groove 930, one end of the limit pin 494 is fixedly set on the block No. 191, and the other end of the limit pin 494 extends into the No. 1 waist-shaped groove 930, and both sides of the lower end of the clamping block 493 are set to be wedge-shaped.

[0045] During actual use, when the product is placed on the rotating material placement rack 45, the wedge-shaped surface on the outside of the clamping block 493 is squeezed, so that the clamping block 493 moves upward to compress the No. 2 spring 492. During this process, the No. 1 waist-shaped groove 930 moves upward synchronously and then abuts against the lower end of the limit pin 494. When the hard disk bracket 100 is placed in place, the No. 2 spring 492 is reset, so that the hard disk bracket 100 is clamped from the side by the clamping block 493.

[0046] In the above design, the structural design and specific implementation of the elastic pressing piece 49 can effectively realize the rapid pressing of the hard disk bracket 100 .

[0048] During actual use, the slide 73 is driven by the No. 1 cylinder 74 to move along the No. 1 linear guide rail 72 toward the side of the fixture 4, so that the positioning column 762 extends into the positioning hole 402 of the fixture 4, and then the positioning frame 76 is driven to rotate by the driving assembly 77, so that the positioning column 762 drives the rotating discharge frame 45 to rotate synchronously.

[0049] In the above design, the structural design and specific implementation method of the first turning mechanism 7 can effectively realize the rapid rotation of the rotating material placing frame 45 of the fixture 4.

[0054] In actual use, the linear module 113 drives the slide frame 114 to move to the working position, and then the No. 2 cylinder 117 drives the lifting frame 116 to move downward, and then the two clamping claw cylinders 119 clamp the side wall of the hard disk bracket 100, and then the linear module 113 drives the slide frame 114 to move away from the fixture 4, so that the hard disk bracket 100 is separated from the rotating material rack 45. When the hard disk bracket 100 is transferred to the top of the conveyor line 111, the No. 2 rotary cylinder 118 drives the clamping claw cylinder 119 to rotate, and then the No. 2 cylinder 117 drives the lifting frame 116 to move downward, and the product is placed on the conveyor line 111.
