Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] like Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: an automatic labeling device for a USB flash drive interface. It includes a workbench 1. A turntable 12 is rotatably mounted on the workbench 1. Multiple elastic clamping mechanisms are mounted on the turntable 12. The multiple elastic clamping mechanisms are evenly distributed circumferentially on the turntable 12.

[0021] Specifically, the turntable 12 has multiple placement slots 13 evenly distributed around its circumference. Each placement slot 13 corresponds to an elastic clamping mechanism, and the elastic clamping mechanism is installed in the corresponding placement slot 13.

[0022] Furthermore, the elastic clamping mechanism includes: a clamping plate 14 and a second spring 15.

[0023] Wherein: two clamping plates 14 are provided. The two clamping plates 14 are placed in parallel. The clamping plates 14 are slidably installed in the placement groove 13.

[0024] Multiple second springs 15 are provided. The extension and retraction direction of the second springs 15 is perpendicular to the clamping plate 14. One end of the second spring 15 is fixed to the clamping plate 14. The other end of the second spring 15 is fixed to the side wall of the placement groove 13.

[0025] When in use, the USB flash drive is placed between the two clamps 14, and the elastic force of the second spring 15 causes the clamps 14 to clamp the USB flash drive.

[0026] Preferably, the upper surface of the clamping plate 14 is set as an inclined surface. The inclined surface causes the two clamping plates 14 to form a V shape when brought close together.

[0027] The clamping plate 14 has a sloping structure. When installing a USB flash drive, simply align the USB flash drive with the two clamping plates 14, bringing them close together to form a V-shaped opening, and press the USB flash drive downwards. As the USB flash drive moves downwards, the sloping surfaces press the clamping plates 14 outwards, causing the clamping plates 14 to move away from each other, thus installing the USB flash drive between the two clamping plates 14. The sloping structure on the clamping plate 14 makes installing USB flash drives faster.

[0028] A vertical fixed plate 2 is fixedly installed on the workbench 1. A reciprocating lead screw 4 with its axis set in the vertical direction is rotatably installed on the fixed plate 2. A first slider 6 is threadedly connected to the reciprocating lead screw 4.

[0029] Specifically, the fixing plate 2 has a vertical first sliding groove 3. The first slider 6 is slidably connected to the first sliding groove 3.

[0030] A motor 5 is fixedly mounted on the fixing plate 2. The output shaft of the motor 5 is arranged in a vertical direction and is connected to the reciprocating lead screw 4.

[0031] Start motor 5. The rotation of motor 5 drives the reciprocating lead screw 4 to rotate. When the reciprocating lead screw 4 rotates, it drives the first slider 6 to move up and down along the first slide groove 3.

[0032] A labeling structure 11 is vertically slidably connected to the fixed plate 2. The labeling structure 11 is slidably mounted on the first slider 6.

[0033] The first slider 6 moves up and down, causing the labeling structure 11 to move up and down, so that the labeling structure 11 moves closer to or further away from the USB flash drive.

[0034] Specifically, the first slider 6 has a second sliding groove 7 in the front-to-back direction. A second slider 8 is slidably installed in the second sliding groove 7. A first spring 9 is fixedly installed on the second slider 8. One end of the first spring 9 is fixed to the second slider 8, and the other end of the first spring 9 is fixed to the side wall of the second sliding groove 7. A connecting rod 81 protruding from the first slider 6 is fixedly installed on the second slider 8, and the connecting rod 81 is detachably connected to the labeling structure 11.

[0035] When the labeling mechanism's labeling structure 11 moves downwards and comes into contact with the USB drive, there will be a certain amount of friction between the labeling structure 11 and the USB drive as the labeling structure 11 continues to move downwards. This friction is greater than the elastic force of the second spring 15. This friction causes the second slider 8, connecting rod 81, and labeling mechanism's labeling structure 11 to slide along the direction of the second slide groove 7 as the USB drive rotates. This means that the labeling mechanism's labeling structure 11 is in a relatively stationary state relative to the USB drive, thereby improving the labeling quality and preventing scratches or damage to the label caused by friction between the labeling mechanism's labeling structure 11 and the USB drive.

[0036] When the labeling mechanism 11 moves upward and disengages from the USB flash drive, the friction disappears. Under the action of the first spring 9, the second slider 8 drives the labeling mechanism 11 to move in the opposite direction and reset.

[0037] A drive mechanism for driving the turntable 12 to rotate is installed between the reciprocating lead screw 4 and the turntable 12.

[0038] Specifically, the drive mechanism includes: a first pulley 10, a connecting column 16, a second pulley 17, and a belt 18.

[0039] Wherein: the lower end of the reciprocating lead screw 4 passes through the worktable 1 and is located below the worktable 1. The first pulley 10 is fixedly installed on the lower end of the reciprocating lead screw 4.

[0040] The connecting column 16 is rotatably mounted on the lower end of the worktable 1. The upper end of the connecting column 16 passes through the worktable 1 and is fixedly connected to the turntable 12.

[0041] The second pulley 17 is fixedly connected to the connecting post 16. The diameter of the second pulley 17 is larger than the diameter of the first pulley 10.

[0042] The belt 18 is fitted between the first pulley 10 and the second pulley 17.

[0043] The transmission ratio between the first pulley 10 and the second pulley 17 is reasonably selected based on the number of elastic clamping mechanisms. The selection requirement is that the reciprocating screw 4 drives the labeling structure 11 to move up and down reciprocally for one cycle, so that the rotation angle of the turntable 12 is equal to the angle between the adjacent elastic clamping mechanisms. This ensures that when the labeling structure 11 moves to its lowest position after labeling the USB flash drive of one of the elastic clamping mechanisms, the adjacent USB flash drive rotates to be below the labeling structure 11.

[0044] The specific usage method of this embodiment is as follows: Initial state: The labeling structure 11 is located at the bottom of its displacement, with one of the elastic clamping mechanisms opposite to the labeling structure 11.

[0045] First, place the USB flash drive into the placement slot 13 along the inclined surface of the clamping plate 14. The two clamping plates 14 will automatically clamp the USB flash drive under the action of the second spring 15, which can prevent the USB flash drive from shifting its position during subsequent rotation.

[0046] Then, start motor 5. Motor 5 drives reciprocating screw 4 to rotate. Reciprocating screw 4 drives labeling structure 11 to move up and down reciprocally.

[0047] At the same time, the reciprocating screw 4 drives the first pulley 10 to rotate. This causes the second pulley 17 to rotate under the influence of the first pulley 10 and the belt 18. Consequently, the connecting column 16, the turntable 12, and the USB flash drive are all driven to rotate together.

[0048] Because the reciprocating screw 4 drives the labeling structure 11 to move up and down for one cycle, the rotation angle of the turntable 12 is equal to the angle between the adjacent elastic clamping mechanisms. Therefore, when the labeling structure 11 moves downward again, the turntable 12 drives the next adjacent elastic clamping module to rotate below the labeling structure 11.

[0049] When the labeling mechanism's labeling structure 11 moves downwards and comes into contact with the USB drive, there will be a certain amount of friction between the labeling structure 11 and the USB drive as the labeling structure 11 continues to move downwards. This friction is greater than the elastic force of the second spring 15. This friction causes the second slider 8, connecting rod 81, and labeling mechanism's labeling structure 11 to slide along the direction of the second slide groove 7 as the USB drive rotates. This means that the labeling mechanism's labeling structure 11 is in a relatively stationary state relative to the USB drive, thereby improving the labeling quality and preventing scratches or damage to the label caused by friction between the labeling mechanism's labeling structure 11 and the USB drive.

[0050] When the labeling mechanism 11 moves upward and disengages from the USB flash drive, the friction disappears. Under the action of the first spring 9, the second slider 8 drives the labeling mechanism 11 to move in the opposite direction and reset.

[0051] Repeat the above steps, and the labeling structure 11 will label the USB flash drives in different positions in turn. Example 2

[0052] This embodiment is a further improvement based on Embodiment 1.

[0053] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: an automatic labeling device for a USB flash drive interface. A fixing post 19 is added based on Embodiment 1. Specifically: Multiple fixing posts 19 are provided. Each fixing post 19 corresponds to one of the elastic clamping mechanisms. The fixing posts 19 are located outside the elastic clamping mechanisms. The fixing posts 19 are fixedly installed on the turntable 12, and the axis of the fixing posts 19 is arranged in the vertical direction. The connecting rod 81 cooperates with the fixing posts 19.

[0054] In this embodiment: before the labeling mechanism labeling structure 11 contacts the USB flash drive, the fixing post 19 first contacts the connecting rod 81. Then, as the fixing post 19 is rotated by the turntable 12, the connecting rod 81 is fixed, and the first spring 9 pushes the second slider 8 to move along the second groove 7. Then, as the labeling mechanism labeling structure 11, connecting rod 81, and first slider 6 continue to move downwards as a whole, the labeling mechanism labeling structure 11 contacts the USB flash drive, thus completing the labeling operation on the USB flash drive.

[0055] After labeling is completed, as the reciprocating screw 4, turntable 12, and fixed post 19 continue to rotate, the labeling mechanism labeling structure 11, connecting rod 81, and first slider 6 will move upward as a whole, thus moving the labeling mechanism labeling structure 11 away from the USB drive. During this process, relative sliding will occur between the connecting rod 81 and the fixed post 19, causing the labeling mechanism labeling structure 11 to continue moving a certain distance with the rotation of the USB drive until the labeling mechanism labeling structure 11 is completely separated from the USB drive. That is, there is only vertical displacement between the labeling mechanism labeling structure 11 and the USB drive, eliminating lateral movement and thus ensuring the quality of labeling.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
