Description

  The present invention relates to an assembly jig for a linear motor, and more particularly to an assembly jig for a linear motor that is suitable for use in assembling a linear motor stator on a surface mounter or the like.

  In a surface mounter that mounts electronic components on a printed circuit board using a mounting head, a linear motor is adopted as a drive mechanism for linearly moving the mounting head. When the linear motor is attached to the surface mounter, an assembly operation is performed in which a plurality of magnet members are arranged and fixed along the moving direction of the mounting head in order to form a stator of the linear motor.

  Since the magnet member constituting the stator has strong magnetism, when the operator manually assembles the finger, his / her fingers are caught in the magnet member attracted to the work table by the magnetic force, thereby causing injury. In addition to the danger, a tool such as a bolt may be attracted to the magnet member to hinder the work.

  Therefore, in Patent Document 1, as shown in FIG. 1, an assembly jig made of a non-magnetic material is provided on the magnetic surface side of the magnet member 14 when the magnet member 14 constituting the stator is attached to the arrangement position of the frame 15b. 21 is temporarily fixed by a bolt 22, and the assembly member 21 is temporarily fixed and the magnet member 14 in a state where the magnetic force is interrupted is attached and fixed at the arrangement position, thereby causing a risk caused by the magnetic force of the magnet member 14. Techniques that prevent deterioration of workability and workability have been proposed.

JP 2005-31228 A

  However, in the assembling jig 21 used in the assembly of the linear motor disclosed in Patent Document 1, the ribs 21a provided at four locations around the magnet member 14 are temporarily fixed to the magnetic surface side. Since the bolts 22 are screwed to each other, the temporary fixing bolts 22 need to be attached and removed one by one in use, which has a problem of poor workability.

  The present invention has been made to solve the above-mentioned conventional problems, and when assembling a linear motor, it can be easily temporarily fixed to the magnetic surface of the magnet member constituting the stator and can be easily removed. An object of the present invention is to provide an assembly jig for a linear motor that can be used.

  When assembling a stator of a linear motor, the present invention uses a linear motor that is temporarily fixed by bringing a magnetic member into contact with a contact surface of a main body made of a non-magnetic material to a magnet member constituting the stator. In the assembling jig, the magnetic material embedded in the main body, and a separating means for separating the abutting surface of the main body abutted on the magnetic surface of the magnet member against the magnetic surface against a magnetic force; By providing the above, the above-mentioned problems are solved.

  In the present invention, the separating means may be a push screw type attaching / detaching knob.

  According to the present invention, since the magnetic material is embedded in the main body of the assembly jig made of the non-magnetic material, the magnetic material can be obtained simply by bringing the contact surface of the main body into contact with the magnetic surface of the magnet member. The assembly jig can be reliably adsorbed and temporarily fixed by the magnetic force (magnetic attractive force) acting on the. In addition, after use, the magnetic attracting force can be weakened rapidly by simply pulling the contact surface away from the magnetic surface against the magnetic force by the separating means. Can be removed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  2, 3, and 4 are a plan view, a front view, and a side view schematically showing a state in which the linear motor assembly jig according to one embodiment of the present invention is temporarily fixed to a magnet member constituting the stator, respectively. FIG.

  The basic shape of the assembly jig 30 of this embodiment is the same as that of the assembly jig 21 shown in FIG. 1, and a main body (substantially rectangular plate member) 32 made of a nonmagnetic material made of plastic or the like. An attachment / detachment knob (pull-out) made of a screw member screwed in the thickness direction of a magnetic material 34 made of iron or the like embedded in the body 32 and a rib portion 32A continuously formed at four locations around the body 32. Separating means) 36.

  Further, a handle 38 is attached to the main body 32 of the assembly jig 30 on the upper side in the drawing so that the assembly jig 30 can be easily carried.

  As shown in the figure, the assembling jig 30 is such that a lower abutting surface 32B in the figure is brought into contact with a magnetic surface (front surface side) of a magnet member 42 whose back side is joined to a base plate 40. Temporarily fixed. This temporary fixing is realized by a magnetic attractive force with respect to the magnetic material 34 simply by placing the assembly jig 30 on the magnet member 42 and bringing it into contact therewith.

  The detachable knob 36 is a rotary type, and as shown in FIGS. 5 and 6 corresponding to FIGS. 3 and 4, is manually operated in the “positive” direction indicated by an arrow to act as a push screw. Since the tip of the screw portion 36A forcibly pushes down the base plate 40, the main body 32 of the assembly jig 30 is lifted from the magnet member 42 and pulled away, so that the assembly jig 30 is removed from the magnet member 42. Can do. Conversely, when the detachable knob 36 is turned in the “negative” direction so that the tip of the threaded portion 36A is at the same level as or above the upper surface of the base plate 40, as shown in FIGS. Since the contact surface 32B of the assembly jig 30 is in close contact with the magnetic surface of the member 42, the assembly jig 30 can be temporarily fixed to the magnet member 42 by a magnetic force.

  Next, the case where the magnet member 42 is attached to the frame 15b shown in FIG. 1 in the same manner as in the prior art using the assembly jig 30 of the present embodiment will be described.

  The attaching / detaching knob 36 of the assembling jig 30 is rotated in the “positive” direction, and the screwing portion 36A is pushed into the main body 32, and the assembling jig 30 is placed on the magnet member 42 constituting the stator. 5 and 6, the attaching / detaching knob 36 is turned in the “negative” direction, and the screw is raised as shown in FIGS. 42 abut and temporarily fix.

  The assembly jig 30 temporarily fixed to the magnet member 42 is positioned at the arrangement position of the frame 15b shown in FIG. The positioned magnet member 42 is fixed to the base plate 40 supporting the magnet member 42 with the fixing hole 40A and the screw hole 15d of the frame 15b, and screwed in the same manner as in the prior art.

  Thereafter, the attaching / detaching knob 36 is turned in the “positive” direction, and the assembly jig 30 is detached from the magnet member 42 in the state shown in FIGS.

  According to the embodiment described above in detail, the following effects can be obtained.

(1) Since the magnetic material 34 is embedded in the main body 32 made of a non-magnetic material of the assembly jig 30, the assembly jig 30 is simply placed on and brought into contact with the magnet member 42 constituting the linear motor stator. It can be easily temporarily fixed by magnetic attraction.

(2) Since the attachment / detachment knob 36 is provided on the assembly jig 30, the magnet member 42 and the assembly jig 30 can be attached / detached only by manually turning the knob 36, so that the assembly work of the stator can be facilitated. .

(3) Since the assembly jig 30 can be easily carried using the handle 38, the assembly work of the linear motor can be carried out safely and with good workability.

  The number and size of the magnetic material 34, the embedding position, and the like are not limited to those shown in the embodiment, and are arbitrary as long as temporary fixation can be realized.

  Further, the number and attachment positions of the attachment / detachment knobs 36 are arbitrary. Further, the separating means is not limited to the attaching / detaching knob 36 formed of a push screw, and may be forcibly separated using, for example, the lever principle.
