JP 2001-310268 A

  As described above, in the assembling apparatus described in Patent Document 1, the ring body to which the magnetic force is applied to the driver bit is fitted and the screw is held. However, if the assembling operation is performed in a space having a strong magnetic force, for example, in the vicinity of a permanent magnet of a speaker, the screw held by the driver bit is attracted to the magnetic material, and the assembling workability is significantly reduced. There was a problem.

  Therefore, an object of the present invention is to provide an assembly apparatus capable of suppressing a decrease in assembly workability even when the assembly operation is performed in a space having a strong magnetic force.

  The assembly apparatus according to the present invention comprises an assembly tool for attaching parts to an assembly and assembling a product, and a shield for shielding magnetism emitted from the assembly, the shield being the assembly described above. A first position for shielding the magnetism to the part mounted on the tool, and a second position for mounting the part on the assembly movably provided on the assembly tool It is.

  According to the present invention, the assembling apparatus comprises an assembling tool for attaching parts to an assembly and assembling a product, and a shield for shielding magnetism emitted from the assembly, the shielding being an assembly The assembly tool is movably provided with a first position for shielding the magnetism of the parts mounted on the housing and a second position for attaching the parts to the assembly.

  Therefore, since the shield is at the first position when the component is attached to the assembly tool, and the shield is at the second position when the component is attached to the object to be assembled, the assembly operation is performed in a strong magnetic space. Also in the case of performing the assembly work, the assembly operation can be performed without the parts being attracted to the assembly by magnetism before the parts are attached to the assembly. Thereby, the fall of assembly workability can be suppressed.

Embodiment
(Constitution)
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a state in which an assembling apparatus 100 according to the embodiment holds a screw 2. FIG. 2 is a front view of the assembly apparatus 100 with the screw 2 attached to the speaker 10. FIG. 3 is an exploded front view of the driver bit 1 and the shield 3 of the driver 7. FIG. 4 is a plan view of the assembling apparatus 100 with the screw 2 attached to the speaker 10.

  As shown in FIGS. 1 and 2, the assembling apparatus 100 includes a driver 7, a shield 3, a protector 4, and a spring 5 as an elastic body.

  The driver 7 is an assembly tool for attaching a screw 2 as a part to an assembly and assembling a product. More specifically, the driver 7 is an assembly tool for rotating the screw 2 and attaching it to an assembly, and includes a driver bit 1 and a driver grip 6. The driver bit 1 is made of a metal material and rotates a screw 2 attached to the tip. The driver grasping unit 6 is made of, for example, a resin material. The driver grasping portion 6 grasps the driver bit 1 by fixing the base end portion of the driver bit 1 to the lower end portion of the driver grasping portion 6. In the present embodiment, a case in which the speaker 10 is adopted as an assembled product will be described.

  The shield 3 has a cylindrical shape made of a soft magnetic material, and the inner diameter thereof is larger than the outer diameter of the driver bit 1 and the head of the screw 2. The shield 3 has the same rotation axis and center axis of the driver bit 1. One end of the spring 5 is fixed to the lower end of the driver grip 6, and the other end is fixed to the upper end of the shield 3. The shield 3 is provided on the outer peripheral portion of the driver bit 1 via a spring 5. The shield 3 is fixed to the driver grip 6 via a spring 5 inserted into the base end of the driver bit 1. The length of the shield 3 is smaller than the length of the driver bit 1, more specifically, about 2/3 of the length of the driver bit 1. Thereby, the shield 3 can cover the tip side of the driver bit 1.

  Since the magnetic body is provided at or near the tip of the driver bit 1, the driver bit 1 can mount and hold the screw 2.

  The shield 3 is fixed to the driver grasping portion 6 via the spring 5, and thus can be moved in the vertical direction by the elastic force of the spring 5. More specifically, the shield 3 has a first position (see FIG. 1) for shielding magnetism to the screw 2 attached to the driver bit 1 by the elastic force of the spring 5 and a speaker 2 A second position (see FIG. 2) for attachment to 10 is movable. In the normal state, the shield 3 is located at the second position shown in FIG. 2 by the biasing force of the spring 5.

  As shown in FIG. 3 and FIG. 4, the shield 3 is an outer peripheral portion of the shield 3 so that positioning at the time of screwing can be performed according to the shape of the portion in contact with the speaker 10 as an assembly. Positioning part 3a is formed in a part of. The positioning portion 3a is formed in a cylindrical inward concave shape, that is, in an arc shape in plan view so as to abut on the side surface of the permanent magnet 10a which is a circular portion of the speaker 10. Therefore, the positioning portion 3a can guide the shield 3 from the second position to the first position while in contact with the side surface of the permanent magnet 10a.

  The protector 4 is made of a material that absorbs an impact, and covers the entire outer periphery of the shield 3. Here, the material that absorbs impact is, for example, a soft material such as urethane sponge.

(Operation)
Next, the operation of the assembling apparatus 100 will be described. FIG. 5 is an operation explanatory view of a state in which the assembling apparatus 100 attaches the screw 2 to the speaker 10.

  As shown in FIG. 1, when the screw 2 is attached to the driver bit 1, the shield 3 is pushed to the lower first position so that the tip side of the driver bit 1 and the screw 2 are covered by the shield 3. It will be. Thus, the screw 2 is attached to and held by the driver bit 1.

  When the screw 2 is attached to the speaker 10, the shield 3 is pressed against the speaker 10 in an attempt to attach the screw 2 to the desired screw hole 10b of the speaker 10 by holding the driver grip 6 in the state shown in FIG. Then, as shown in FIG. 2, the shield 3 is moved to the upper second position by the biasing force of the spring 5, and the screw 2 enters the screw hole 10b.

  Further, as shown in FIGS. 4 and 5, the positioning portion 3a of the shield 3 is brought into contact with the side surface of the permanent magnet 10a of the speaker 10, and the rotation axis and center axis of the driver bit 1 are made the same. The screw 2 is precisely attached to the speaker 10 and the casing 11 of the product by positioning the screw tightening so that 2 is at the center of the screw hole 10 b.

(effect)
As described above, the assembling apparatus 100 according to the embodiment includes the assembling tool for attaching the parts to the assembly and assembling the product, and the shield 3 for shielding the magnetism emitted from the assembly, The body 3 is provided on the assembly so as to be movable in a first position for shielding the magnetism of the component mounted on the assembly tool and in a second position for attaching the component to the assembly.

  Therefore, since the shield 3 is at the first position when the component is attached to the assembly tool, and the shield 3 is at the second position when the component is attached to the object to be assembled, Even in the assembly operation, the assembly operation can be performed without the parts being attracted to the assembly by magnetism before the components are attached to the assembly. Thereby, the fall of assembly workability can be suppressed. Thus, the yield of the product can be improved.

  In particular, the assembling apparatus 100 can be suitably used in an operation of screw-fastening the speaker 10 having the ferromagnetic permanent magnet 10a to the product housing. The component is a screw 2, the assembly tool is a driver 7 having a driver bit 1 for attaching the screw 2 to a speaker 10 by rotating the screw 2, and the shield 3 is a cylindrical shape made of a soft magnetic material. The shield 3 has the same rotation axis as that of the central axis of the driver bit 1 and is provided on the outer peripheral portion of the driver bit 1 via the spring 5 so as to be movable between the first position and the second position.

  Therefore, even in the operation of attaching the screw 2 to the speaker 10 having the ferromagnetic permanent magnet 10a, before attaching the screw 2 to the speaker 10, the operation of attaching the screw 2 without the screw 2 being attracted to the speaker 10 by magnetism It can be carried out. Thereby, the fall of workability can be suppressed. Further, the screw 2 can be attached to the speaker 10 and the casing 11 of the product with high accuracy.

  The shielding body 3 was provided with the positioning part 3a which guides from the second position to the first position in a state where the shielding body 3 is in contact with the permanent magnet 10a of the speaker 10.

  Therefore, the screw 2 can be guided such that the center of the driver bit 1 and the screw 2 are in the center of the screw hole 10b in a state where the shield 3 abuts on the side surface of the permanent magnet 10a. Thereby, even if the position of the screw 2 can not be visually confirmed by the shield 3, the relative position of the screw hole 10b of the speaker 10 and the screw 2 can be made clear, and the efficiency of the assembling operation can be further enhanced.

  The outer peripheral part of the shielding body 3 was covered, and the protector 4 which consists of a material which absorbs an impact was further provided. Therefore, under the influence of the magnetic field of the permanent magnet 10a, the shield 3 made of a soft magnetic material is attracted to the permanent magnet 10a. When the shield 3 abuts on the permanent magnet 10 a, the protective tool 4 can reduce the impact of the contact between the shield 3 and the permanent magnet 10 a, so that the speaker 10 can be prevented from being scratched. Thereby, the efficiency fall of assembly work can be suppressed.

  Note that, instead of the driver 7, an electrically driven driver such as an electric drill driver may be employed. Also in this case, the shield 3 may be movably provided to the driver grasping portion of the electrically driven driver via a spring or the like.

  In addition, the shield 3 may be formed using a transparent magnetic material having light transparency. The transparent shield 3 facilitates the mounting of the screw 2 and the confirmation of the screwing position of the assembly, which further increases the efficiency of the assembling operation. Here, the transparent magnetic material is, for example, a nanogranular material.

  In the present invention, within the scope of the invention, the embodiment can be appropriately modified or omitted.
