Abstract

(57) [Abstract] [Purpose] The present invention is designed for XY in case of a fall accident during transportation.
The purpose of the invention is to prevent damage to the box 7 that houses the control unit 3 of the drive device and to improve the workability for reinforcing the box 7. [Structure] The structure of the XY drive device of the present invention is a box in which an X-axis drive mechanism 1 and a Y-axis drive mechanism 2 are mounted on a molded body frame 4, and a control unit 3 is housed under the body frame 4. In the XY drive device to which 7 is attached, the main body frame 4 is formed so that the outsides of the corner portions 10 at the four corners of the box 7 are covered with the ears 11 extended from the main body frame 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a portal type rectangular coordinate system XY driving device for positioning in the X-axis direction and the Y-axis direction.

[0002]

[Prior Art]

 FIG. 4 and FIG. 5 show a gate-shaped rectangular coordinate system composed of a mechanism unit for positioning by a conventional X-axis drive mechanism 1 and a Y-axis drive mechanism 2 and a control unit 3 thereof. A structural example of a system XY drive device is shown. Reference numeral 4 is a main body frame integrally formed of a light alloy or the like for attaching the drive mechanism 1 in the X-axis direction and the drive mechanism 2 in the Y-axis direction. Further, a convex foot portion 5 that supports the entire apparatus is formed on the lower side of the main body frame 4, and a box 7 accommodating the control unit 3 is screwed to the lower end surface 6 of the foot portion 5, and the entire apparatus It has a structure in which rubber feet 8 for supporting are attached. A connection connector 9 for connecting various cables is attached to the side surface of the box 7. With such a configuration, the XY drive mechanisms 1 and 2 and the control unit 3 are integrally configured, so that the entire apparatus can be made compact and simple.

[0003]

[Problems to be solved by the device]

 The box 7 for accommodating the control unit 3 is generally made of a thin iron plate or the like for cost reduction and weight reduction. However, in the event of a drop accident during transportation, if the corner part 10 of the box 7 is shocked when it is dropped, the box 7 is not rigid and may be immediately damaged, and even the internal control part 3 may be destroyed. It was Further, the connector 9 attached to the side surface was also exposed from the box 7 and was easily damaged by external force or shock. Therefore, it has been transported by reinforcing the corner portion 10 of the box 7 or in a strong packaging form so that the corner portion 10 is not impacted. Further, since the corner portion 10 of the box 7 is visible from the outside, it is necessary to weld the abutting surface with brazing and to finish it neatly with a sander (not shown), which causes a cost increase. The present invention is intended to prevent damage to the box 7 attached to the lower side of the main body and to improve the workability of the box 7 in the event of a drop accident during transportation.

[0004]

[Means for Solving the Problems]

 The structure of the XY drive device of the present invention is such that the X-axis drive mechanism 1 and the Y-axis drive mechanism 2 are mounted on the molded body frame 4, and the box 7 containing the control unit 3 is mounted on the lower side of the body frame 4. In the XY drive device, the main body frame 4 is formed so that the outer sides of the corner portions 10 at the four corners of the box 7 are covered with the ears 11 extended from the main body frame 4.

[0005]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of an XY drive device including an X-axis drive mechanism 1, a Y-axis drive mechanism 2 and a control section 3 thereof according to the present invention. 4 is each drive mechanism 1, A body frame integrally molded with a light alloy for attaching 2. A box 7 is attached to the lower side of the main body frame 4, and the outside of the corners 10 at the four corners is formed so as to cover the ears 11 extended from the main body frame 4. Reference numeral 9 is a connection connector for connecting various cables attached to the side surface of the box 7. As shown in the vertical sectional front view of FIG. 2, the box 7 is screwed from the lower end surface of the convex foot portion 5 extending downward from the main body frame 4, and the foot portion 5 further includes the entire device. Rubber feet 8 for supporting are attached. FIG. 3 shows an embodiment in which the corner portion 10 of the box 7 is reinforced, and the bracket 12 is spot-welded to the corner portion 10.

[0006]

[Action]

 In the XY drive apparatus configured as described above, when a fall accident occurs during transportation and a shock is applied to the main body, the corner portion 10 of the box 7 is a solid frame 4 integrally molded from the outside and an ear extended from the frame 4. The surroundings are protected by the part 11 and are not damaged. Further, the connector 9 exposed on the side surface of the box 7 can be similarly protected by the frame 4 surface. Further, by covering the corner portion 10 so as not to be directly visible, brazing of the corner portion 10 and subsequent sander finishing can be eliminated.

[0007]

[Effect of the device]

 As can be seen from the above description, according to the present invention, it is possible to provide a strong structure that can withstand a fall accident during transportation and a shock applied from the outside with a simple structure, and a simple and inexpensive transportation form. You can Further, since the corner portion 10 of the box 7 is hidden by the ears 11 of the main body frame 4 and cannot be directly seen by the eyes, it can be reinforced by spot welding, which is easy to process, and the processing cost can be significantly reduced compared to the conventional case. it can.
