DETAILED DESCRIPTION

[0026] The present invention will be described more clearly and completely below by way of a preferred embodiment in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiment.

[0027] like Figure 1-Figure 4The figure shows a memory stick buckle release device disclosed in the present invention, comprising a sliding frame 1, on which are symmetrically provided movable mounting blocks 2 which are slidably connected to the sliding frame 1 along the same straight line direction, a push block assembly 3 for pushing the buckle is provided below the movable mounting block 2, connecting rods are hinged on both movable mounting blocks 2, and the connecting rods are hinged to each other through a connecting rod 3 at one end away from the movable mounting block 2, and a driving mechanism for pushing the connecting rod 4 to move in a direction perpendicular to the sliding direction of the movable mounting block 2 is provided above the sliding frame 1, and when the driving mechanism drives the connecting rod 4 to move, the connecting rod rotates around the connecting rod 4 to drive the movable mounting block 2 to slide on the sliding frame 1.

[0028] The present invention drives the connecting rod 4 to move up and down through the driving mechanism, thereby moving the connecting rod hinged to the connecting rod 4, driving the movable mounting block 2 to slide on the sliding frame 1, and opening the buckle. Since the two connecting rods are driven by the same driving mechanism, the synchronization of the sliding of the two movable mounting blocks 2 can be ensured, so that the buckles on both sides of the memory stick are opened synchronously, thereby avoiding damage to the buckles of the memory stick.

[0029] Specifically, the sliding frame 1 of the present invention includes a fixed block 5 and a sliding shaft 6. The sliding shaft 6 is inserted into the fixed block 5. The movable mounting block 2 is connected to the sliding shaft 6 by a linear bearing 7 and slides along the axial direction of the sliding shaft 6. An oil pressure buffer 8 for slowing down the sliding speed of the movable mounting block 2 is provided on the outer side of the sliding direction of the movable mounting block 2. The oil pressure buffer 8 is fixed by a buffer mounting plate 23. The sliding shaft 6 makes the sliding direction of the movable mounting block 2 consistent and can withstand the force perpendicular to the axial direction to avoid deflection. The oil pressure buffer 8 absorbs the kinetic energy generated by the driving mechanism, reduces the speed of the movable mounting block 2 when it reaches the buckle, avoids damage to the buckle due to collision, and makes the buckle opening process smooth.

[0030] like Figure 4 As shown, the push block assembly of the present invention includes a floating mounting plate 9, a push block 10 and a push block mounting plate 11. The push block 10 is fixed on the push block mounting plate 11. Preferably, the push block 10 is made of polyurethane, which is an elastic material. When the push block is working, it contacts the buckle through the soft material to prevent the buckle from being damaged when the mechanism moves abnormally; a guide rod 12 parallel to the sliding shaft 6 is fixed on the push block mounting plate 11, and a spring 13 is sleeved on the guide rod 12. A second linear bearing 14 matching the guide rod 12 is provided on the floating mounting plate 9, and the guide rod 12 is provided with a boss for preventing disengagement at the outer end of the second linear bearing 14. The end of the guide rod 12 is inserted into the second linear bearing 14, and the spring 13 is located between the push block mounting plate 11 and the floating mounting plate 9. The thrust of the push block 10 when the buckle is opened is controlled by the compression amount of the spring 13. A plurality of gaskets 15 are provided on the guide rod 12. The number of gaskets 15 , where L is the compressible length of the spring without a gasket, N is the buckle-opening thrust, k is the elastic coefficient of the spring, and t is the thickness of a single gasket.

[0031] The thrust can be controlled by adjusting the number of gaskets 15, which is fast and convenient, does not require changes to the main structure, can reduce labor, and improve efficiency. At the same time, the thickness of each gasket determines the adjustment accuracy and grading, which has good practicality and high adjustment accuracy.

[0032] For different servers, the number and specifications of memory card buckles therein may be different, which requires that the buckle opening range of the buckle opening device can be adjusted to improve its versatility. The driving mechanism of the present invention includes an adjustable stroke cylinder 16, a cylinder mounting plate 17 and a guide plate 18. The cylinder mounting plate 17 is arranged on the guide plate 18. The adjustable stroke cylinder 16 is fixed by the cylinder mounting plate 17. The driving end of the adjustable stroke cylinder 16 is connected to the connecting rod 4. By adjusting the pushing stroke of the adjustable stroke cylinder 6, the sliding distance of the movable mounting block 2 is changed to realize the opening requirements of buckles of different sizes, realize one machine with multiple uses, and have a wide range of uses. The guide plate 18 is fixed to the fixed portion of the sliding frame 1. On the block 5, the fixed block 5 is fixedly connected with the buffer mounting plate 21, and a connecting hole 24 for connecting with the mobile end of the robot or servo module is provided on the buffer mounting plate 21. The buckle opening device is driven to move by the sliding frame as a whole, and can be moved to a designated position on the production line to perform buckle opening operation under the drive of the robot or manipulator; the plate surface of the guide plate 18 of the present invention is perpendicular to the connecting rod 4, and a follower wheel 19 is connected to the end of the connecting rod 4 close to the guide plate. The follower wheel 19 cooperates with the guide groove 20 provided on the guide plate 18 to guide the movement of the connecting rod 4, so that the sliding of the connecting rod 4 is more stable, and the sliding distance symmetry of the two movable mounting blocks 2 is fully guaranteed.

[0033] Since the connecting rod and the connecting rod 4 are hinged to each other, the ordinary hinge method will cause the axes of the two connecting rods to deviate, and then cause the movable mounting block 2 connected to the connecting rod to deviate in the sliding distance. The longer the stroke, the greater the deviation. In order to fully ensure the consistency of the sliding distances of the two movable mounting blocks 2, the connecting rod of the present invention includes a first connecting rod 21 and a second connecting rod 22. The axes of the first connecting rod 21 and the second connecting rod 22 are in the same plane, and mutually engaging concave-convex structures are provided at the ends of the first connecting rod 21 and the second connecting rod 22. The connecting rod 4 is inserted into the concave-convex structure. When the adjustable stroke cylinder 16 pushes the connecting rod 4 to move up and down, the first connecting rod 21 and the second connecting rod 22 rotate around the connecting rod 4 at the same angle, and the corresponding movable mounting blocks 2 move at the same distance, so that the buckles on both sides are opened and closed synchronously.

[0034] When the present invention is in use, the stroke of the adjustable stroke cylinder and the number of gaskets 15 that need to be added are first set according to the size of the buckle. The device can be moved to the buckle by using a robot or a mechanical arm, and the stroke of the adjustable stroke cylinder 16 is deduced according to the actual position of the buckle, and the appropriate number of gaskets is selected. After the stroke and number are determined, the entire device is fixed on the robot or the cylinder or servo module through a fixed block, and the motion mechanism is used to move up and down to each buckle position for buckling. If necessary, the camera lens vision can be used to perform precise buckling actions. When the size of the buckle changes, the moving stroke of the adjustable stroke cylinder can be adjusted again and the number of gaskets can be increased or decreased. After the adjustment is completed, the buckle opening operation is performed again.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
