- the present invention relates to processing a Positioniervorrich ⁇ , particularly for a placement head of an Be Glaautoma ⁇ th for populating substrates with electrical Bauelemen ⁇ th.
- a positioning device known from WO 99/44407 comprises a carrier arm, which is displaceably guided along a linear guide. While the support arm is mounted at one end by a fixed bearing, the rotor of a linear motor is fixed at its opposite end, which is encompassed by a fixed to the chassis of the positioning, U-shaped aus ⁇ formed stator of the linear motor. In addition, a guide rail on Chas ⁇ sis is mounted on the side of the linear motor, which is mounted on the support arm from being ⁇ guide roll up and gripped below.
- the Positioniervorrich- processing has the disadvantage that it ⁇ accelerate the strong loading and braking in the support arm to elastic Verfor ⁇ provisions of the support arm in the direction of movement is such that ei ⁇ ne exact positioning can be ensured only after sufficient decay of the vibration of the support arm ,
- the game in the camp also causes inaccuracies in the positioning.
- the support arm of the positioning device is at one end by a fixed bearing and at the opposite end by a loose support bearing in a direction of movement the carrier arm movably mounted.
- the support arm On the part of the movable bearing, the support arm is supported on a guide surface, which is formed parallel to the direction of movement and obliquely to a plane defined by the direction of movement and the extension axis of the support arm surface.
- means for generating a force acting on the support arm force are provided such that the support arm is loaded on the side of the support bearing with an additional bearing force perpendicular to the guide surface of the support bearing.
- extra support force is to be understood that this bearing force acts in addition to the ⁇ by the weight of the bearing arm her pre-called bearing force on the support arm.
- the support arm receives a force in the direction of the guide ⁇ surface and thereby Pulled or pressed on this.Thus, there are numerous advantages
- the oblique embodiment allows the guide surface of the loose support bearing a thermal Ausdeh ⁇ voltage of the carrier arm. Thermal material tension in the support arm or tilting of the support arm in the bearings is thereby avoided. Furthermore, not only a vertical but above all a good lateral support results for the support arm by the slope of the guide surface, wherein the support effect is considerably enhanced by the force generated by the above-mentioned means.
- Carrier arm occurs, significantly reduced.
- the desired Po ⁇ can sition with the inventive positioning device so quickly and be approached with precision.
- the carrier arm is driven by a linear arm motor whose rotor and stator are arranged in such a way. net are that the linear motor at the same time assumes the function of the drive and the means for generating the force acting on the support arm force. This both the high Po sitionier accuracy can a linear motor and the strong be- seen the stator and the rotor magnetic force acting out ⁇ be utilized.
- the rotor of the linear motor at the end of the support arm on which the loose support bearing is so the arm on the ⁇ poor acting, directed perpendicular to the guide surface force and thereby the lateral support of the support arm is particularly strong ,
- the positioning device according to the invention can also be designed An ⁇ demanding 4 to the effect that the hard ⁇ spanned surface is oriented shelf parallel to the movement direction and oblique to a direction by the movement of the axis of extension and of the support arm. This ge ⁇ the rigidity and stability are increasing the support arm on.
- FIG. 1 shows a side view of a first exemplary embodiment of the positioning device according to the invention in the direction of movement of the carrier arm
- FIG. 2 shows a plan view of the first exemplary embodiment of the positioning device according to the invention shown in FIG.
- FIG. 3 represent a side view of a second embodiment of the positioning device according to the invention.
- a first embodiment of the present invention positio ⁇ niervorraum 1 is shown in Figures 1 and 2.
- FIG. This is a positioning device 1 for a placement head 2 of a placement machine 3, as it is used for the loading of substrates 4 with electrical components.
- the placement machine 3 has a chassis 5, on the upper side of a working plane is formed.
- a Transportstre ⁇ bridge 6 is provided, transported on the substrates to be loaded 4 to a placement position and can be transported away again after the placement of die ⁇ these.
- the working plane is spanned by the positioning device 1 transversely to the transport direction of the substrates 4.
- the positioning device 1 comprises a support arm 7, which is mounted at one of its ends by a fixed bearing 8 and at its opposite end by a loose support bearing 9 in a direction parallel to the transport direction of the substrates 4 moving direction x relative to the chassis 5 of the placement machine 3 slidably.
- the support arm 7 thus extends transversely to the direction of movement x.
- a 9 provided Linearmo on the side of the loose support bearing serves ⁇ gate 10.
- the rotor 11 of the linear motor 10 on Trä ⁇ gerarm 7 and the stator 12 of the linear motor 10 at a small distance to the chassis 5 of the placement 3 intended.
- located on the support arm 7 of the placement 2 which by means of its own drive (not shown) in the direction y of the extension axis of the support arm 7, ie transversely to the direction of movement x of the support arm 7, is movable.
- the loose support bearing 9 of the positioning device 1 consists of at least one provided on the support arm 7 support roller 13 (this embodiment is not shown), which is supported along a trained on the chassis 5 of the placement machine 3 th guide surface 14.
- the unwinding direction of the support roller 13 is oriented in the direction of movement x of the support arm 7.
- this is preferably in the neutral phase of Trä- gerarms 7, ie arranged in the direction of movement x centered on the support arm.
- air bearings or slide bearings can be provided.
- two support rollers 13 are provided.
- the support rollers 13 are arranged one behind the other in the direction of movement and their unwinding direction is oriented in the direction of movement x of the support arm 7.
- the guide surface 14 of the support bearing 9 is parallel to the direction of movement of the support arm 7 and formed obliquely to a plane defined by the direction of movement and the extension axis of the support arm 7 surface.
- the running surface of the linear motor 10 extends in this embodiment, also obliquely to the plane defined by the direction of movement and the extension axis of the support arm 7 surface.
- Positioniervor ⁇ device 1 Another advantage of the invention Positioniervor ⁇ device 1 is that the inclined guide surface 14 allows the supporting bearing 9 ⁇ thermal deformations of the support arm 7 in the direction of the axis of extension.
- the support arm 7, for example when heated can expand in the direction of its extension axis, since the support rollers 13 can move upwards along the guide surface 14 of the support bearing 9. Thermal material stresses or tilting of the bearings thus do not occur.
- the support arm 7 is biased by the magnetic force in the direction of its extension axis ⁇ , so that the game is taken from the opposite Festla ⁇ ger 8.
- the fixed bearing 8 is formed in a similar manner as the movable bearing parallel to the direction of movement and obliquely to a by the movement direction and the Motherre ⁇ ckungsachse of the support arm 7 spanned surface.
- the carrier arm 7 is widened in the region of the bearings. As a result, the rigidity increases, and the tendency to torsion during braking and accelerating is considerably reduced.
- the present invention is based on the principle that the positioning device 1 via means (in the Ausure ⁇ tion of the linear motor 10) for generating a force acting on the support arm 7 (in the embodiment, the magnetic force F M ), so that a force (in this case the force F L ) acts on the support arm 7 in the direction of the guide surface 14 of the loose support bearing 9 and the support arm is pulled or pushed onto the guide surface 14 of the support bearing 9.
- this also means that the running surface of the linear motor 10 does not necessarily have to be inclined, but that it is only important that at least one component of the between see the stator 12 and the rotor 11 acting magnetic force F M pulls the support arm 7 on the guide surface 14 of the support bearing 9.
- the above-described lateral support effect can be achieved.
- the largest supporting force is achieved when the running surface ⁇ and the guide surface 14 of the support bearing 9 are arranged in parallel. The greater the deviation from the parallelism is ty ⁇ , the smaller is the component of the magnetic force F M which pulls the support arm 7 on the guide surface fourteenth
- the drive of the positioning device 1 is formed as a linear motor 10, which simultaneously performs the function of the means for generating the force acting on the support arm 7 supporting force F L by the acting magnetic force F M , other embodiments of Invention conceivable.
- the drive of the positioning device 1 can also be realized by a belt drive or a spindle drive, in which case the means for generating the support force acting on the support arm 7 must be provided separately.
- This agent can then, for example, a correspondingly provided on the support arm 7 permanent magnets ⁇ th 15 (as shown in Fig. 3) act, which is in gerin ⁇ gem distance with provided on the chassis 5 ferromagnetic plates interact.
- a further possibility for generating the force acting on the support arm 7 would also be the attachment of a pneumatic suction device (reverse air bearing) on the support arm 7 which pulls the support arm 7 in accordance with the principle of the invention in the direction of the guide surface 14 of the support bearing 9 presses.
- a pneumatic suction device reverse air bearing
- the loose support bearing 9 can be realized instead of a roller bearing as an air bearing. The freedom from friction of the air bearing resulting in the positioning device 1 further advantages.
- the linear motor 10 is on the Side of the support arm 7 is provided on which the loose support bearing 9 is located.
- This embodiment brings the Vor ⁇ part of a favorable force transmission to the support arm 7 in the direction of the guide surface 14 of the support bearing 9 with it.
- the linear motor 10, or the means for generating the force acting on the carrier arm can in principle also be provided on the side of the fixed bearing 8.
