Definitions
- the invention relates to a device for holding a gripper for an electrical component on a placement head, the gripper being detachably attachable to an end section of an essentially cylindrical shaft of the placement head.
- the concentricity of the pipette tip is impaired with a component held thereon.
- the component must be rotated from a removal position in a mounting position before being placed on a printed circuit board, which can result in a corresponding lateral offset.
- An eccentricity of the pipette tip particularly in the case of very small components, can lead to them being sucked in eccentrically and drawn into the suction channel and disturbing the pneumatic functions of the placement head.
- the O-Rmg has relatively large manufacturing tolerances, which lead to the fact that the push-on and pull-off forces vary over a wide range.
- the O-Rmg Since the grippers have to be replaced relatively frequently depending on the components to be gripped, the O-Rmg must be regreased frequently and carefully with considerable maintenance in order to avoid a correspondingly high level of frictional wear. Even the carefully maintained 0-ring is subject to residual wear, which requires periodic replacement. Since the change frequency of the individual pipettes cannot be monitored automatically, it is correspondingly difficult to adjust the maintenance intervals so that the pressure function is reliably performed at all times, so that an angular deviation between the axes of the shaft and the suction pipette cannot always be avoided.
- a holding device for fixing a suction pipette to a mounting head which has a hollow-cylindrical centering bushing, which can be used with a convex-cylindrical connecting pin of the suction pipette.
- the connecting pin has an annular groove m which engage the radially deflectable locking balls of the mounting head, which are released when the pipette is changed by pushing back a clamping bush.
- Such active locking requires a relatively large mechanical outlay, with a correspondingly large outer diameter in the region of the holding section.
- the required slenderness of the pipette can only be achieved by a corresponding extension of the pipette, but through which the pipette tip of
- Holding section is further away, which reduces their positional accuracy.
- the invention has for its object to enable a secure and accurate fixation of the gripper on the shaft with little manufacturing and maintenance. This object is lost by the invention according to claim 1 ge ⁇ .
- the locking domes can be arranged in a precisely defined position and dimension on the shaft. They can have an abrasion-resistant and smooth surface that is subject to wear. The depth of the locking groove is so small that the required mutual deflection is in the range of elastic compliance.
- the axial offset between the locking groove and the locking crests can be set to an exact dimension, so that the axial contact forces can be limited much more precisely.
- the push-on and pull-off forces can also be limited to a narrower tolerance range, as a result of which the average actuating force can be reduced.
- the locking domes according to claim 2 result in point-like contact between the shaft and the gripper, which favors the mutual deflection when it snaps into place.
- the annular groove according to claim 3 can be formed exactly concentrically with the cylindrical centering section, so that the metal balls can be arranged exactly in their radial installation position.
- the locking balls according to claim 4 are inexpensive available as standard parts of high accuracy and high strength and good sliding properties. By pouring out the entire ring groove, the balls are firmly connected to the shaft.
- the casting material according to claim 5 is of such a tough consistency that it adheres to the ring groove without further aids before curing.
- the locking balls can be inserted into this material by simply impressing them.
- the embodiment defined in claim 6, the gripper wall so far is bendable from its cylindrical shape found that a ⁇ towards reaching yielding during locking without permanent Ver ⁇ modeling can be achieved. It is particularly advantageous here if between three and five balls are distributed in the ring groove. This results in a secure centering with sufficient flexibility.
- FIG. 1 shows a longitudinal section through an assembly head with a shaft and a gripper
- FIG. 2 shows a cross section along the line II-II in FIG. 1
- FIG. 3 shows an enlarged section through the parts according to FIG
- a movable gripper 1 for an electrical component 8 is provided with a vertical, essentially cylindrical shaft 2, at the lower end of which a gripper 3 designed as a suction pipette is exchangeably held, which has a thin-walled socket section is attached to the lower end of the shaft 2.
- An annular groove 4 is embedded in the latter, the depth of which is somewhat less than the diameter of locking balls 5 distributed all around the annular groove 4 m.
- the cross section of the inner part of the annular groove is rounded and has a somewhat larger radius than the locking balls, as a result of which a secure Investment in the groove base is possible.
- a circumferential locking groove 6 is formed in the inner wall of the bush section of the gripper 3 m in height of the annular groove, m engaging the locking balls 5 with their outer tips.
- the annular groove is offset in the axial direction from the locking groove by the amount s that the upper end face of the gripper 3 is pressed against a circumferential collar-shaped stop 7 of the shaft 2.
- a centering section 9 around which the inner wall of the gripper 3 engages around the shaft 2 without play, so that it is exactly centered with respect to the shaft axis.
