[0032] A clamping assembly 6, the clamping assembly 6 is arranged at the bottom of the third robotic arm 44, and the clamping assembly 6 includes a suction cup seat 61 and a pusher 62.

[0033] The support column 1 has a supporting function, and a base is fixedly connected to the bottom, and the support column 1 can be fixed to the ground by bolts, which increases the stability of the support column 1. The function of the control box 2 is to control the operation of the device. The function of the starting assembly 3 is to start and control the movement and fixation of the rotating assembly 4. The function of the rotating assembly 4 is to adjust the position of the clamping assembly 6 by rotation. The function of the braking assembly 5 is to brake the rotating assembly 4 in time when the cylinder 31 loses air. The function of the clamping assembly 6 is to clamp goods.

[0034] The cylinder 31 is movably connected to the surface of the support column 1 near the top, and the cylinder 31 is fixedly connected to the surface of the cylinder 31.

[0035] A rod is fixedly connected to the surface of the support column 1 near the top. The bottom of the cylinder 31 is rotatably connected to the surface of this plate, and the top is rotatably connected to the left end of the first robotic arm 42. By the telescoping and angle change of the cylinder 31, the angle of the first robotic arm 42 can be adjusted, and the pressure sensor 32 can monitor the pressure of the gas inside the cylinder 31 in real time.

[0036] The connecting seat 41 is fixedly connected to the top of the support column 1. One end of the first robotic arm 42 is movably connected to the top of the cylinder 31. The first robotic arm 42 is movably connected inside the connecting seat 41. The second robotic arm 43 is movably connected to the top of the connecting seat 41. The third robotic arm 44 is movably connected to the bottom of the other end of the second robotic arm 43.

[0037] The number of connecting seats 41 is two. The two connecting seats 41 are respectively fixedly connected to the top of the support column 1 and rotatably connected to the right end of the first robotic arm 42. The surface of the first robotic arm 42 near the left end is rotatably connected to the inner surface of the connecting seat 41 at the top of the support column 1. One end of the second robotic arm 43 is rotatably connected to the top of the right connecting seat 41. The third robotic arm 44 is rotatably connected to the bottom of the other end of the second robotic arm 43. By the change of the vertical angle of the first robotic arm 42, the horizontal rotation of the second robotic arm 43 and the self-rotation of the third robotic arm 44, the omnidirectional position and height adjustment of the clamping assembly 6 are completed.

[0038] The braking gear disc 51 is fixedly connected to the surface of the connection end of the first robotic arm 42 and the connecting seat 41. The bidirectional telescopic rod 52 is fixedly installed on the outer surface of one end of the connecting seat 41. The braking racks 53 are fixedly connected to both ends of the bidirectional telescopic rod 52. The limiting groove 54 is opened on the outer surface of the connecting seat 41.

[0039] The number of the braking assemblies 5 is two. In each group, the two braking gear discs 51 are respectively fixedly connected to the surfaces of the connection ends of the two rods and the two connection seats 41 in the first robotic arm 42. The bidirectional telescopic rod 52 is fixedly installed on the outer surface of the connection seat 41 between the two braking gear discs 51. In each group, the two braking racks 53 are fixedly connected to the two ends of the bidirectional telescopic rod 52. When the first robotic arm 42 rotates, the braking gear discs 51 rotate therewith. When the air cylinder 31 loses air, the bidirectional telescopic rod 52 pulls the two braking racks 53 inward. And on the surfaces of the two braking racks 53 near the upper and lower ends, there is respectively fixedly connected with a block, and the two blocks are respectively slidably embedded in the two limiting grooves 54 to play a limiting role until the two braking racks 53 are engaged with the two braking gear discs 51, locking the braking gear discs 51, and the braking gear discs 51 cannot rotate, so that the first robotic arm 42 cannot rotate either.

[0040] The sucker seat 61 is fixedly connected to the bottom of the third robotic arm 44, and the pusher 62 is fixedly connected to the surface of the sucker seat 61.

[0041] The sucker seat 61 is L-shaped, and a plurality of suckers are fixedly installed on the inner surface. The goods are adsorbed by the suckers, and then the pusher 62 is pushed. Through the angular change of the rotating assembly 4, the transportation of the goods by the sucker seat 61 is realized.

[0042] The working principle of a pneumatic assist manipulator air-loss protection device provided by the present utility model is as follows:

[0043] First, the goods are adsorbed on the suckers on the surface of the sucker seat 61, and then the pusher 62 is held by hand to push the sucker seat 61. At this time, the third robotic arm 44 rotates itself to adjust the azimuth angle of the sucker seat 61, the second robotic arm 43 rotates horizontally to adjust the circumferential position of the sucker seat 61, and the first robotic arm 42 rotates vertically with the connection end with the connection seat 41 at the top of the support column 1 as the center to adjust the circumferential position and the height of the sucker seat 61. During this process, the air cylinder 31 expands and contracts following the rotation of the first robotic arm 42. When the first robotic arm 42 rotates to any position, the air cylinder 31 stops supplying air, so as to fix the first robotic arm 42 and complete the transportation of the goods. When the air cylinder 31 suddenly loses air, the pressure sensor 32 senses the pressure of the gas inside the air cylinder 31 and sends a signal to the control box 2. The control box 2 controls the bidirectional telescopic rod 52 on the two connection seats 41 to pull the braking racks 53 at its two ends to be engaged with the braking gear discs 51, so that the braking gear discs 51 cannot rotate, and the connection end of the first robotic arm 42 with the connection seat 41 cannot rotate either, realizing the braking of the first robotic arm 42.

[0044] Compared with the related art, a pneumatic assist manipulator air-loss protection device provided by the present utility model has the following beneficial effects:

[0045] The utility model provides a pneumatic loss protection device for a power-assisted manipulator. The rotation of the rotating assembly 4 can be realized through the air cylinder 31, so as to complete the conveying of goods by the clamping assembly 6. Moreover, the air pressure inside the air cylinder 31 can be sensed by the pressure sensor 32. When the air cylinder 31 loses air, the pressure sensor 32 sends a signal to the control box 2, and the control box 2 controls the bidirectional telescopic rod 52 to start, so that the two braking racks 53 are connected to the surface of the braking gear disc 51, thereby realizing the braking of the rotating assembly 4 and preventing the goods from suddenly falling and causing casualties, which improves the safety performance of the device.
