Definitions
- the invention relates to a device for handling and/or performing work operations on objects.
- the invention is applicable in the industrial sector in movement systems of small-mass objects weighing a few kilograms, and for which fast and precise movement is required.
- the invention is applicable in systems for gathering and positioning products, known as "pick and place” systems, in lines of packaging or assembly of products, in machines for separating and/or sorting products or in object handling systems.
- the present invention can be used in the medical field for moving and handling surgical instruments, or in the field of mechanical working for moving tools such as millers, drill bits, pliers or the like, or for the movement and training of precision instruments in general, such as for example lasers.
- Robot arms composed of a plurality of hinged link mechanisms, which at an end thereof bear a tool, such as pliers, a sucker or any other work instrument.
- a tool such as pliers, a sucker or any other work instrument.
- the object located on a horizontal plane or on a conveyor belt is gathered and moved, parallel to the work plane or with its orientation changed with respect to the plane, to be deposited internally of a special housing or a second conveyor belt.
- Robot architectures developed in the prior art are essentially of two types: arms of the traditional type (generally anthropomorphic) or robots having parallel kinematics mechanisms.
- Parallel kinematics machines obviate the above-described dynamic limitation by concentrating all the actuators in the robot zone which remains fixed, transferring the movement to the object via a complex mechanical structure of mechanical links, often comprising more than one arm, which is however light and rigid.
- the aim of the present invention is to obviate the drawbacks encountered in the solutions of the prior art.
- the aim of the present invention is to realise a device for handling and/or performing work operation on objects which combine the work volumes characteristic of anthropomorphic structures with the high- level dynamics and precision of parallel kinematics machines.
- an aim of the present invention is to realise a device for handling and/or the performance of work operations on objects which enables a reduction in the masses in motion, in particular in the zone closest to the object, enabling performance-giving dynamics, a decidedly large work volume and an extremely simple control structure.
- FIG. 1 is a perspective view of a device for handling objects, according to the present invention
- figure 2 is a front view of a detail of the device of figure 2
- figure 3 is an enlarged view of a detail of figure 2.
- 1 denotes a device for handling and/or performing work operations on objects in accordance with the present invention.
- the device 1 comprises a first arm 2 and a second arm 3, each exhibiting a first end 2a, 3a and a second end 2b, 3b.
- the arms 2, 3 are advantageously straight and develop along a respective longitudinal axis Z.
- the axes Z of the two arms 2, 3 are preferably parallel to one another.
- the first arm 2 and the second arm 3 are preferably made of carbon.
- the device 1 further comprises a support body 4 to which both the first arm 2 and the second arm 3 are connected by the respective first ends 2a, 3 a thereof.
- the device 1 exhibits, associated to the second ends 2b, 3b of each arm 2, 3, means for supporting and moving 5.
- the means for supporting and moving 5 are preferably designed to support and move a tool 9.
- the device 1 comprises at least a first linear electric motor 6a and a second linear electric motor 6b, respectively associated to the first arm 2 and the second arm 3, which move the arm 2, 3 to which they are associated.
- each linear motor 6a, 6b moves the respective arm 2, 3 along a straight sliding direction Zl, Z2.
- the sliding directions Zl, Z2 of the arms 2, 3 are preferably parallel to one another, and even more preferably are parallel to the axis Z of the two arms 2,
- the sliding direction of the first arm 2 is independent of the sliding movement of the second arm 3.
- the first and second arms 2, 3, activated by the respective linear electric motors 6a, 6b, can be alternatingly mobile along the respective sliding direction Zl, Z2, or can move together.
- the first and second linear electric motors 6a, 6b are preferably ironless.
- the coil is arranged between two facing tracks of permanent magnets and the flow is almost totally combined with the turns of the coil.
- the ferromagnetic nucleus is absent internally thereof, making the motor light.
- the means for supporting and moving 5 are preferably articulated and comprise at least a first con rod 7 and a second con rod 8, hinged to one another at respective first ends thereof 7a, 8a.
- the second end 7b, 8b of each con rod is hinged to a respective arm 2, 3.
- the second end 7b of the first con rod 7 is hinged to the second end 2b of the first arm 2, and the second end 8b of the second con rod 8 is hinged to the second end 3b of the second arm 3.
- the means for supporting and moving 5 support a tool 9; in particular, the tool 9 is connected to a single con rod, for example the first con rod 7, as shown in figure 3.
- the tool 9 can advantageously be a gripping instrument, such as pliers or a sucker, or a work tool, such as a drill, a miller, a laser or the like.
- any type of tool can be connected to the means for supporting and moving 5, according to needs.
- the first con rod 7 and the second con rod 8 define, together with the second end 2b, 3b of each arm 2, 3, a four-bar link, enabling the tool 9 to move on an arc of circumference comprised between +/- 90°.
- the range of the circumference swept by the tool 9 depends on design choices, and in particular on the distance between the two arms 2, 3 which is generally fixed, and by the length of the con rods 7, 8.
- the movement of the tool 9 about the rotation axis 9a thereof is caused by a tradition electric motor 10, associated to the con rod bearing the tool 9.
- Both the arms 2, 3 are slidably associated to the support body 4.
- the support body 4 comprises a third linear motor 11, to which the first arm 2 and the second arm 3 are connected by respective first ends 2a, 3 a thereof.
- the linear motor 11 therefore comprises a linear guide 12 and a slide 13 which is mobile thereon.
- the first ends 2a, 3a of each arm 2, 3 are constrained to the slide 13.
- the guide 12 is oriented along a direction X which is transversal, and preferably perpendicular, to the sliding direction Zl, Z2 of the arms 2, 3.
- the tool 9 apart from shifting along an arc of circumference, rotating about the rotation axis 9a thereof, and translating along a parallel direction to the axis Z of the arms 2, 3, can also translate along a transversal direction to the direction of the axis Z of the arms 2, 3.
- the invention offers important advantages since it provides a structure having contained dimensions, which is able to manage work volumes which are characteristic of anthropomorphic structures, but with the high dynamics and precision typical of parallel kinematics machines. This is obtained by means of a non-conventional kinematic structure specially designed to be able to exploit direction-motion innovative actuators, which do not require the interposing of supplementary mechanical organs.
- the linear electric motors directly command the element to which they are applied, avoiding the presence of kinematic connections which make the structure heavy, increase the amount of moving parts and slow down the working speed and the dynamics of the machine.
