[0002] In the production and assembly process of some electronic products, the method of using carriers for transfer and transportation is widely used. Although carriers have the advantages of convenient product placement, compact space, and adaptability to different space occasions, they are inconvenient for transfer and transportation. In actual production, it is usually necessary to rotate the carrier to a certain angle after clamping to meet the material placement posture, so as to facilitate the robot to quickly pick up materials for assembly.

[0003] In the prior art, most mechanisms are single transport carriers, which are inefficient and cannot be flipped at any angle to achieve the material discharge posture, and cannot meet the needs of automated production. Utility Model Content

The pulleys are jointly equipped with a transmission belt. It also includes a tensioning wheel rotatably mounted on the outer side of the clamping arm for tensioning the transmission belt.

[0012] The structure of the mobile driving mechanism is as follows: it includes a moving block slidably mounted on the horizontal plate of the lifting seat, one end of the moving block is fixedly mounted on the clamping arm, and the other end of the moving block is connected to the output end of the cylinder; a limit block is installed on the horizontal plate, and stoppers are installed on the moving block at intervals, and the stoppers are located on both sides of the limit block.

[0013] The cylinders in the two groups of mobile drive mechanisms are arranged on a horizontal plate in an up-and-down structure; a slider guide assembly is installed between the mobile block and the horizontal plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] When the utility model is used, the mobile driving mechanism drives the clamping arms on both sides to move toward each other, and the clamping claws clamp the grasped object, and then the rotating shaft drives the clamping claws to rotate through the connecting shaft and the rotating shaft to realize the flipping of the grasped object; the connecting component simultaneously ensures the transmission of the rotating power of the connecting shaft and the transmission of the moving power of the clamping arm, so as to realize the angle flipping during clamping and transportation.

[0032] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, a clamping, flipping and transporting mechanism of this embodiment includes a lifting seat 3, on which a horizontally arranged rotating shaft 8 is rotatably mounted, and connecting shafts 40 are mounted at both ends of the rotating shaft 8 through connecting components 4, as shown in FIG. Figure 3 As shown, the connecting component 4 includes an inner cylinder member 42 and an outer cylinder member 43 which are axially slidably assembled; it also includes a clamping arm 6 which is rotatably mounted on the connecting shaft 40, a rotating shaft 50 is rotatably mounted through the clamping arm 6, and a clamping claw 10 is mounted on the rotating shaft 50 located on the inner side of the clamping arm 6; the clamping arm 6 is driven by the mobile driving mechanism 9 to move axially along the rotating shaft 8, and the rotating shaft 50 and the connecting shaft 40 are dynamically connected via the rotating transmission component 5.

[0034] When in use, the mobile driving mechanism 9 pushes the clamping arms 6 on both sides to move toward each other, and the clamping claws 10 clamp the grasped object. Then, the rotating shaft 8 drives the clamping claws 10 to rotate through the connecting shaft 40 and the rotating shaft 50 to realize the flipping of the grasped object; the connecting component 4 simultaneously ensures the transmission of the rotational power of the connecting shaft 40 and the transmission of the moving power of the clamping arm 6, thereby realizing the angle flipping during clamping and transportation.

[0035] In this embodiment, through the setting of the connecting component 4, the transmission of the rotational power from the rotating shaft 8 to the connecting shaft 40 is effectively guaranteed. At the same time, the connecting shaft 40 can move with the clamping arm 6 under the drive of the moving drive mechanism 9, that is, the connecting shaft 40 can move axially relative to the rotating shaft 8, thereby effectively simplifying the structure and ensuring the clamping and flipping action of the clamping claw 10 at the end of the clamping arm 6.

[0036] The inner cylinder 42 and the connecting shaft 40 are fixed as a whole and can rotate or move synchronously; in actual use, they can be locked together by fasteners or formed as an integral part.

[0037] In another embodiment, the connecting shaft 40 extends into the inner cylinder 42, and a circumferential rotation limiting structure is provided between the outer wall of the connecting shaft 40 and the inner wall of the inner cylinder 42, that is, the connecting shaft 40 rotates synchronously with the inner cylinder 42, but its axial direction can move relatively.

[0038] In this embodiment, the circumferential rotation limiting structure may be a rib or groove structure arranged along the axial direction on the circumferential surface.

[0039] A connection key 41 is installed on the outer circumferential surface of the inner cylinder 42, and a sliding groove for the connection key 41 to move relative to the axial direction is provided on the inner wall surface of the outer cylinder 43.

[0040] In this embodiment, the inner cylinder member 42 and the outer cylinder member 43 in the connection assembly 4 maintain circumferential synchronous rotation and axial relative sliding power transmission through the connection key 41 and the slide groove.

[0041] The end of the rotating shaft 8 is inserted into the outer cylinder 43 , and the end of the rotating shaft 8 is matched with the inner hole of the outer cylinder 43 via a rectangular structure, so that when the rotating shaft 8 rotates, the outer cylinder 43 is driven to rotate synchronously.

[0042] The rotating shaft 50 is arranged parallel to the lower part of the connecting shaft 40. The rotating transmission assembly 5 includes pulleys respectively mounted on the rotating shaft 50 and the connecting shaft 40. The pulleys are jointly equipped with a transmission belt. The pulleys also include a tensioning wheel rotatably mounted on the outer side of the clamping arm 6 for tensioning the transmission belt.

[0043] The structure of the mobile driving mechanism 9 is as follows: it includes a moving block 95 slidably mounted on the horizontal plate 30 of the lifting seat 3, one end of the moving block 95 is fixedly mounted on the clamping arm 6, and the other end of the moving block 95 is connected to the output end of the cylinder 91; a limit block 93 is installed on the horizontal plate 30, and stoppers 94 are installed on the moving block 95 at intervals, and the stoppers 94 are located on both sides of the limit block 93.

[0044] When in use, the air cylinder 91 works, and drives the clamping arms 6 to move via the moving block 95, so that the two clamping arms 6 move toward each other for clamping or move away from each other for releasing the clamping.

[0045] The cylinders 91 in the two groups of mobile drive mechanisms 9 are arranged in an upper and lower structure on the horizontal plate 30, making the overall structural layout of the conveying mechanism compact; a slider guide assembly 92 is installed between the moving block 95 and the horizontal plate 30, which effectively ensures the smoothness and reliability of the relative movement of the moving block 95 on the horizontal plate 30.

[0046] like Figure 4 As shown, the rotating shaft 8 is rotatably supported on the lifting seat 3 by shaft seats 80 arranged at intervals; a shading sheet 82 is mounted on the rotating shaft 8, and a slot-shaped photoelectric sensor 81 is provided below the shading sheet 82; when the rotating shaft 8 rotates, the shading sheet 82 rotates accordingly, and the slot-shaped photoelectric sensor 81 senses the shading sheet 82 to provide feedback on the rotation of the rotating shaft 8.

[0047] A pendulum block 83 is mounted on the rotating shaft 8 , and a limiting member 84 is mounted on the side of the shaft seat 80 , and the limiting member 84 limits the angle of rotation of the pendulum block 83 along with the rotating shaft 8 .

[0048] In this embodiment, the pendulum block 83 rotates along with the rotating shaft 8 , and the limiting member 84 constitutes a mechanical limit for the rotation of the pendulum block 83 .

[0049] A motor assembly is installed on the lifting seat 3 , and the motor assembly drives the rotating shaft 8 to rotate via a synchronous belt transmission structure, thereby forming a rotating driving mechanism 7 that drives the rotating shaft 8 to rotate.

[0050] It also includes a horizontal moving module 1 , on which a vertical moving module 2 is installed, and on which a lifting seat 3 is installed.

[0051] In actual use, the horizontal movement during transportation is performed by the horizontal movement module 1, and the vertical movement before and after transportation is performed by the vertical movement module 2, thereby effectively ensuring smooth transportation.

[0052] The usage of the utility model is:

[0053] The horizontal moving module 1 cooperates with the vertical moving module 2 to make the inner clamping claws 10 of the clamping arms 6 on both sides respectively located on both sides of the external clamping object; the cylinders 91 in the two sets of mobile drive mechanisms 9 work, and pull the clamping arms 6 on both sides to move toward each other through the moving blocks 95 until the external clamping object is clamped from both sides. During this process, the inner cylinder member 42 in the connecting component 4 moves axially relative to the outer cylinder member 43, and the inner cylinder member 42 moves horizontally with the connecting shaft 40 and the clamping arm 6; the horizontal moving module 1 and the vertical moving module 2 work to start carrying; at the same time, the motor assembly works to drive the rotating shaft 8 to rotate, and drives the connecting shaft 40 to rotate through the connecting component 4, and the connecting shaft 40 drives the rotating shaft 50 to rotate through the rotating transmission assembly 5, and the clamping claws 10 on both sides rotate to realize the flipping of the external clamping object.

[0054] In this embodiment, according to actual production needs, the rotation of the clamping jaws 10 on both sides can drive the external clamped object to flip to a preset angle, such as 90°, 180°, etc., to meet the needs of subsequent processes.

[0055] The utility model realizes the angle flipping during clamping and carrying, and the overall structure is simple and compact, which meets the demand of rotating while carrying and transferring in actual production, helps to improve production efficiency, and has good practicality.
