Detailed Embodiments

[0028] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.

[0029] As shown Figures 1-5 The present invention provides an automatic balloon grasping system, including: a slideway 1, an upper grasping seat 2, a lower grasping seat 3, a radial grasping mechanism 4, an axial grasping mechanism 5 and a locking mechanism 6;

[0030] The slideway 1 is linear, and the upper grasping seat 2 and the lower grasping seat 3 slide freely in the length direction of the slideway 1. Specifically, the slideway 1 adopts a double-rod structure and is vertically arranged, and the two rods penetrate through the upper grasping seat 2 and the lower grasping seat 3 at the same time;

[0031] The radial grasping mechanism 4 includes a radial opening and closing member 41 and a radial limiting member 42, which are respectively arranged on the upper grasping seat 2 and the lower grasping seat 3. When the radial limiting member 42 approaches or moves away from the radial opening and closing member 41, the opening and closing state of the radial opening and closing member 41 changes;

[0032] The axial grasping mechanism 5 includes an axial opening and closing member 51 and an axial limiting member 52, which are respectively arranged on the upper grasping seat 2 and the lower grasping seat 3. When the axial limiting member 52 approaches or moves away from the axial opening and closing member 51, the opening and closing state of the axial opening and closing member 51 changes;

[0033] The locking mechanism 6 is arranged between the upper grasping seat 2 and the lower grasping seat 3 to control the distance therebetween.

[0034] Specifically, elastic members are arranged in the radial grasping mechanism 4 and the axial grasping mechanism 5 to ensure that the radial grasping mechanism 4 and the axial grasping mechanism 5 have a tendency to automatically open or close. Limiting members are arranged in the horizontal direction, so that when the limiting members approach or move away from the elastic members, the opening and closing states of the radial grasping mechanism 4 and the axial grasping mechanism 5 change; it should be noted that the radial limiting member 42 and the axial limiting member 52 are driven by the same power device and approach or move away from the corresponding elastic members at the same time, and when the limiting members approach or move away from the elastic members, the opening and closing states of the radial grasping mechanism 4 and the axial grasping mechanism 5 are the same. In the automatic balloon grasping system provided by the present invention, the mutual engagement of the elastic member and the limiting member realizes the opening and closing of the grasping system. Compared with the mechanical claws of the traditional multi-stage drive system, the structure is simpler, the manufacturing cost advantage is obvious, the working stability is strong, and it has outstanding market value.

[0035] As an optional implementation manner, the radial opening and closing member 41 includes a first grasping arm and a second grasping arm, and a compression spring is further arranged between the first grasping arm and the second grasping arm.

[0036] As an alternative implementation, the first grasping arm and the second grasping arm are arranged below the upper grasping seat 2, and the upper ends of both are hinged to the upper grasping seat 2.

[0037] As an alternative implementation, the radial limiting member 42 is in an n shape, and the first grasping arm and the second grasping arm pass through the middle of the radial limiting member 42. When the radial limiting member 42 is located at the top of the first grasping arm and the second grasping arm, the radial opening and closing member 41 is in an open state, and when the radial limiting member 42 moves to the lower part of the first grasping arm and the second grasping arm, the radial opening and closing member 41 is in a closed state.

[0038] Specifically, the first grasping arm and the second grasping arm can also adopt wedge-shaped blocks, which are slidably connected to the upper grasping seat 2 in the horizontal direction; preferably, the hinged connection method is adopted, the structure is simpler, the overall structure is more compact, and the required space position is smaller.

[0039] As an alternative implementation, a pair of rolling bearings are also arranged at the position where the inner side of the radial limiting member 42 abuts against the first grasping arm and the second grasping arm, reducing the frictional resistance, making the equipment operation smoother, increasing the service life, reducing the demand for driving performance, and saving production costs.

[0040] As an alternative implementation, the axial opening and closing member 51 includes a pneumatic pressure rod. The upper end of the pneumatic pressure rod is hinged to the upper grasping seat 2, and a tension spring is arranged between the pneumatic pressure rod and the lower grasping seat 3.

[0041] As an alternative implementation, the pneumatic pressure rod is in a side-down M shape, the protrusion in the middle section of the pneumatic pressure rod faces the lower grasping seat 3, and a first roller is arranged on the lower grasping seat 3 and abuts against the middle section of the pneumatic pressure rod.

[0042] Specifically, the upper opening of the side-down M-shaped pneumatic pressure rod is hinged to the upper grasping seat 2, the tension spring between the pneumatic pressure rod and the lower grasping seat 3 is inclined in the vertical direction, the upper end of the tension spring is hooked at the upper corner of the side-down M-shaped pneumatic pressure rod, and the lower end of the tension spring is inclined towards the opening direction of the side-down M-shaped pneumatic pressure rod and is hooked on the lower grasping seat 3; under the elastic force of the tension spring, the lower opening of the side-down M-shaped pneumatic pressure rod has a tendency to approach the lower grasping seat 3, realizing the grasping in the axial direction; under the elastic force of the tension spring, the upper grasping seat 2 and the lower grasping seat 3 have a tendency to approach each other. After the unlocking mechanism 6 is opened, it is ensured that the upper grasping seat 2 and the lower grasping seat 3 approach quickly, and the radial grasping mechanism 4 and the axial grasping mechanism 5 are opened in time.

[0043] As an alternative embodiment, the locking mechanism 6 includes a thrust seat 61 and a locking rod 62; above the upper gripping seat 2, the thrust seat 61 is fixedly connected to the slideway 1; the upper part of the locking rod 62 is hinged to the upper gripping seat 2, and a compression spring is further arranged between the locking rod 62 and the upper gripping seat 2 above the hinge; a limiting protrusion facing the lower gripping seat 3 is arranged at the lower part of the locking rod 62; the top end of the locking rod 62 is bent inwards towards the thrust seat 61, and a second roller is horizontally arranged on the side of the thrust seat 61 corresponding to the upper part of the locking rod 62.

[0044] As an alternative embodiment, the limiting protrusion is triangular, with the tip facing upwards and the bottom edge horizontally arranged. Vertically, the triangular limiting protrusion does not prevent the downward movement of the lower gripping seat 3 from top to bottom, and can prevent the upward movement of the lower gripping seat 3 from bottom to top.

[0045] As an alternative embodiment, a limiting block 8 is arranged on the upper gripping seat 2; vertically, when the limiting block 8 abuts against the nozzle 7 of the balloon to be grabbed, the downward movement of the upper gripping seat 2 stops. Specifically, the driving mechanism is connected to the lower gripping seat 3. When the limiting block 8 does not abut against the nozzle 7 of the grabbed balloon, under the action of the tension spring, the upper gripping seat 2 and the lower gripping seat 3 move simultaneously. When the limiting block 8 abuts against the nozzle 7, the downward movement of the upper gripping seat 2 stops, and the lower gripping seat continues to move downward, and the upper gripping seat 2 and the lower gripping seat 3 move away from each other. Since the balloon vending device itself needs to move the gripping system to change the position of the balloon, with the design of the limiting block 8, the driving device of the moving gripping system can be used to simultaneously adjust the distance between the upper gripping seat 2 and the lower gripping seat 3.
