Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b):

a turnover dispenser is shown in figure 1 and comprises a rack 1, a clamping device and a driving device, wherein the driving device is fixedly connected to the bottom of the rack 1, and the clamping device is rotatably connected to the driving device.

As shown in fig. 1, a groove 8 of an inverted T shape is formed in the bottom of a rack 1, a bidirectional screw rod 9 is rotatably connected to the groove 8, the bidirectional screw rod 9 is arranged along the length direction of the groove 8 and penetrates through the groove 8, two ends of the bidirectional screw rod 9 are provided with two sections of threads which are different in turning direction, two ends of the bidirectional screw rod 9 are respectively in threaded connection with a fixing rod 11, the bottom of the fixing rod 11 is of an inverted T shape, the outer peripheral wall of the bottom of the fixing rod 11 is tightly attached to the inner peripheral wall of the groove 8, the fixing rod 11 is in sliding connection with the groove 8, a motor II 10 is fixedly connected to the rack 1, and an output shaft of the motor II 10 is connected with the bidirectional screw rod 9 in a coaxial transmission manner.

By arranging the two-way screw rod 9, when the two-way screw rod 9 is driven by the motor II 10 to rotate, the two-way screw rod 9 tries to drive the fixing rod 11 in threaded connection with the threaded section to rotate together, because the bottom of the fixing rod 11 is limited in the groove 8, the fixing rod 11 can not rotate together with the two-way screw rod 9, only axial displacement along the two-way screw rod 9 can be generated, the movement of the fixing rod 11 can be decomposed into circumferential movement and axial movement along the two-way screw rod 9, two fixing rods 11 in threaded connection with opposite threads simultaneously displace towards or away from each other, so that the clamping device can rapidly clamp or loosen parts, when the fixing rods 11 approach each other, the two clamping tips 3 approach each other along with the fixing rods 11 until contacting the parts and applying extrusion acting force facing each other to the parts, the parts are clamped, and the static friction force between the parts and the two clamping tips 3 is greater than the gravity borne by the parts, the position of the part is limited, and the clamping device can stably clamp parts with different qualities and shapes by adjusting the extrusion acting force applied to the part by the clamping device, so that the clamping and debugging time of each type of part is shortened.

As shown in fig. 2, the clamping device includes a first motor and two clamping tips 3, the clamping tips 3 are conical, the two clamping tips 3 are arranged coaxially relatively, one end of the clamping tips 3 facing the rack 1 is fixedly connected with the disc 12, the outer peripheral wall of the disc 12 is rotatably connected with two supporting pieces 4 through shaft positioning, the supporting pieces 4 are hook-shaped, when the clamping device is in a static state, the two supporting pieces 4 are respectively positioned right above and right below the disc 12, the clamping tips 3 and the disc 12 are rotatably connected to the top of the fixing rod 11 through a rotating shaft 5, an output shaft of the first motor is in coaxial transmission connection with the rotating shaft 5, a rotating angle of the first motor is 180 degrees in forward and reverse rotation, a rope 6 is wound on the rotating shaft 5, and two ends of the rope 6 are respectively fixedly connected with the two supporting pieces 4 of the same clamping tips 3.

As the clamping tips 3 are conical, the two clamping tips 3 and the clamped parts are simultaneously rotated in the same direction as a whole, the clamping tips 3 and the parts are relatively static in the common rotation process, and no rotating friction force is generated between the clamping tips 3 and the parts, so that the damage of the clamping device to the parts is avoided, in the process that a motor drives a rotating shaft 5 to rotate forwards for 180 degrees, the clamping tips 3 and the parts rotate forwards for 180 degrees together under the driving of the rotating shaft 5, the rope 6 fixedly connected with the supporting piece 4 moving upwards in the same group of supporting pieces 4 winds the rotating shaft 5, so that the length of the rope 6 connected between the supporting piece 4 and the rotating shaft 5 is shortened, the supporting piece 4 is tensioned, the supporting piece 4 rotates towards the direction far away from the parts, so as to be separated from the parts, and the rope 6 fixedly connected with the supporting piece 4 moving downwards in the same group of supporting pieces 4 is loosened from the rotating shaft 5, the length of the rope 6 connected between the supporting piece 4 and the rotating shaft 5 is increased, the supporting piece 4 is loosened, the supporting piece 4 rotates towards the direction close to the parts to gradually contact the parts until the supporting piece contacts the parts, the height of the supporting piece 4 is adjusted through tensioning and loosening of the rope 6, the action is sensitive, the friction loss is small, the movement is stable, when the motor drives the rotating shaft 5 to rotate forwards for 180 degrees, one group of supporting pieces 4 are positioned under the parts, the supporting pieces 4 exert upward supporting force on the parts, the parts can be prevented from being displaced or vibrated, the parts can be prevented from falling off, meanwhile, due to the existence of the supporting pieces 4, the extrusion acting force required for ensuring that an object does not fall off can be properly reduced, the phenomenon that the static friction force between the parts and the clamping tips 3 is too large to crush the surface of the workpiece or cause deformation is avoided, the other supporting piece 4 is positioned over the parts, and does not shield the parts.

When the dispensing device is used for dispensing special-shaped parts, the clamping device is driven by the motor II 10 to move in the opposite direction or in the opposite direction, the parts are clamped or loosened, after the parts are clamped by the clamping device, the positions of the parts are limited, the two clamping tips 3 and the clamped parts are used as a whole and rotate in the same direction, so that the top and bottom surfaces of the parts are completely exposed, the needle head of the dispensing machine can contact each processing surface, and the whole parts are subjected to comprehensive dispensing operation.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
