Description

Technical Field

[0001] This invention relates to the field of relay assembly equipment technology, and more specifically to a pre-assembly device for a relay body and chassis. Background Technology

[0002] In the existing technology, the assembly process of the relay body and chassis usually involves horizontally positioning the relay chassis on the assembly fixture, and then using a robot to insert the relay body parallel to the relay chassis for direct assembly, so that the two are tightly assembled together, thereby realizing the assembly operation of the relay body and chassis. However, due to the structural characteristics of the body and chassis, when the relay body is inserted parallel to the relay chassis for direct assembly, the contact part on the relay body may be scratched by the structure on the relay chassis, which will affect the quality of the relay product. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a pre-assembly device for the relay body and chassis. It mainly solves the technical problem that the assembly process of the existing relay body and chassis may cause the contacts on the relay body to be scratched, thereby affecting the quality of the relay product.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: A pre-assembly device for a relay body and chassis includes a pre-assembly fixture for positioning the relay chassis, a body tilting positioning mechanism for tilting the relay body relative to the assembly surface of the relay chassis at a preset tilting angle, and a robot mechanism. The robot mechanism transfers the relay body, which is tilted and positioned on the body tilting positioning mechanism, to the pre-assembly fixture and pre-tightly assembles it with the relay chassis at a preset tilting angle.

[0005] Furthermore, the relay body, which is tilted and positioned at the tilting positioning mechanism of the main body, is configured to be tilted at a preset tilt angle of 2° to 5° relative to the mounting surface of the relay chassis.

[0006] Furthermore, the relay body is pre-tightly assembled with the relay chassis at a 2°~5° angle relative to the relay chassis.

[0007] Furthermore, the tilt positioning mechanism includes a tilt positioning body, on which a tilt positioning plate with the same tilt angle as the preset tilt angle of the relay body is provided. A positioning block for tilt positioning the relay body is provided on the tilt positioning plate, and a positioning groove for limiting the relay body is formed in the positioning block.

[0008] Furthermore, a first positioning cylinder is provided on the tilting positioning body, and a first preload block that can act on the relay body is connected to the free end of the first positioning cylinder.

[0009] Furthermore, the robotic arm mechanism includes a moving part and an assembly finger part attached to the moving part for grasping the relay body.

[0010] Furthermore, the moving component includes an X-axis lateral movement assembly, a Z-axis lifting assembly is connected to the slide of the X-axis lateral movement assembly, and the finger assembly is fixedly connected to the slide of the Z-axis lifting assembly.

[0011] Furthermore, the pre-assembly device for the relay body and chassis also includes a material picking fixture. The relay body to be assembled is placed horizontally on the material picking fixture. The relay body placed horizontally on the material picking fixture is transferred to the body tilting positioning mechanism by a robotic arm mechanism. The body tilting positioning mechanism tilts and positions the relay body so that the relay body is tilted relative to the assembly surface of the relay chassis at a preset tilt angle.

[0012] Furthermore, the slide of the Z-axis lifting assembly is also equipped with a material-picking finger cylinder.

[0013] Furthermore, the finger assembly component includes a finger assembly cylinder, a positioning reference block and a second positioning cylinder respectively disposed on both sides of the clamping space of the finger assembly cylinder. The free end of the second positioning cylinder is connected to a second pre-tightening block that can act on the relay body. Through the clamping and fixing of the finger assembly cylinder and the clamping and positioning cooperation of the positioning reference block and the second pre-tightening block, the relay body can stably maintain its original tilt angle and be transferred to the pre-assembly tooling position and pre-tightly assembled with the relay chassis in an inclined position.

[0014] The above technical solution has the following advantages or beneficial effects: In the relay body and chassis pre-assembly device of the present invention, the relay chassis to be assembled is positioned on the pre-assembly fixture. The relay body to be assembled is first tilted and positioned by a body tilting positioning mechanism, so that the relay body is tilted relative to the assembly surface of the relay chassis on the pre-assembly fixture at a preset tilt angle. Then, a robotic arm mechanism grasps the relay body and transfers it to the pre-assembly fixture, so that it is tilted and pre-tightly assembled with the relay chassis to be assembled at a preset tilt angle. Then, it can be transferred to the next station for the tight assembly operation of the relay body and the relay chassis. The pre-assembly device has a simple overall structure and is easy to operate. By cleverly tilting and pre-tightly assembling the relay body and the relay chassis to be assembled at a preset tilt angle before tight assembly, the risk of damage to the contacts and other structures on the relay body caused by directly inserting the relay body into the relay chassis for tight assembly can be effectively avoided. This is beneficial to improving the assembly quality of the relay body and the relay chassis, thereby improving the quality of the relay product. Attached Figure Description

[0022] Please refer to the appendix. Figure 1 To be continued Figure 4An embodiment of the present invention provides a pre-assembly device for a relay body and a chassis, including a body tilting positioning mechanism 1 for tilting the relay body 5 relative to the assembly surface of the relay chassis 6 at a preset tilting angle, a pre-assembly fixture 2 for positioning the relay chassis 6, and a robot arm mechanism 3. The robot arm mechanism 3 moves the relay body, which is tilted and positioned on the body tilting positioning mechanism 1, to the pre-assembly fixture 2 while maintaining its original tilting angle, and pre-tightly assembles it together with the relay chassis in an inclined manner. Understandably, in this embodiment, before tightly assembling the relay body 5 and the relay chassis 6, the relay body 5 is pre-tightened to the relay chassis 6 at an incline using the pre-assembly device. Specifically, the relay chassis 6 to be assembled is positioned on the pre-assembly fixture 2. Preferably, the relay chassis 6 is positioned horizontally on the pre-assembly fixture 2. The relay body 5 to be assembled is first tilted and positioned by the body tilting positioning mechanism 1, so that the assembly surface of the relay body 5 relative to the relay chassis 6 on the pre-assembly fixture 2 is tilted at a preset tilt angle. Then, the robotic arm mechanism 3 grabs the relay body 5 and transfers it to the pre-assembly fixture 2 so that it is pre-tightened together with the relay chassis 6 to be assembled at a preset tilt angle. Then, it can be transferred to the next station for the tight assembly operation of the relay body 5 and the relay chassis 6. The pre-assembly device has a simple overall structure and is easy to operate. By cleverly pre-tightening the relay body 5 and the relay chassis 6 at a preset tilt angle before tight assembly, the risk of damage to the contacts and other structures on the relay body 5 due to direct insertion into the relay chassis 6 can be effectively avoided. This helps to improve the assembly quality of the relay body 5 and the relay chassis 6, thereby improving the quality of the relay products.

In this embodiment, preferably, the relay chassis 6 is configured to be horizontally positioned on the pre-assembly fixture 2, and the relay body 5 is tilted and positioned on the body tilting positioning mechanism 1 at a preset tilt angle of 2° to 5° relative to the horizontal plane. However, those skilled in the art should understand that in other embodiments, the tilt angle of the relay body 5 on the body tilting positioning mechanism 1 is not limited to the specific angle range disclosed in this embodiment, as long as it can prevent the structure on the relay body 5 from being scratched during the assembly process with the relay chassis 6.

[0024] Please refer to the appendix. Figure 4 In one preferred embodiment, the tilt positioning mechanism 1 includes a tilt positioning body 11. A tilt positioning plate 12 with the same tilt angle as the preset tilt angle of the relay body 5 is provided on the tilt positioning body 11. A positioning block 13 for tilt positioning the relay body 5 is provided on the tilt positioning plate 12, and a positioning groove for limiting the relay body 5 is formed within the positioning block 13. The relay body 5 to be assembled is positioned within the positioning groove of the positioning block 13. In another preferred embodiment, preferably, one side of the positioning groove is open, and a first positioning cylinder 14 is provided on the tilt positioning body 11. A first pre-tightening block 15 capable of acting on the relay body is connected to the free end of the first positioning cylinder 14. When the first positioning cylinder 14 is activated, the first pre-tightening block 15 presses against the relay body 5 within the positioning groove, thereby improving the tilt angle accuracy and positioning precision of the relay body 5.

A second pre-tightening block 324 that can act on the relay body 5 is connected to the free end of the second positioning cylinder 323. Through the clamping and fixing of the finger assembly cylinder 321 and the clamping and positioning cooperation of the positioning reference block 322 and the second pre-tightening block 324, the relay body 5 can stably maintain its original tilt angle and be transferred to the pre-assembly fixture position 2 and pre-tightly assembled with the relay chassis 6 in an inclined position.

However, those skilled in the art will understand that in other embodiments, the moving component 31 may also include a Y-axis lateral movement assembly, thereby enabling the assembly finger component 32 to move in the XYZ three-axis directions.

[0027] Please refer to the appendix. Figure 1 To be continued Figure 3In one preferred embodiment, the pre-assembly device for the relay body and chassis further includes a material-picking fixture 4. The relay body 5 to be assembled is placed horizontally on the material-picking fixture 4. The robotic arm mechanism 3 transfers the horizontally placed relay body 5 on the material-picking fixture 4 to the body tilting positioning mechanism 1. The body tilting positioning mechanism 1 tilts and positions the relay body 5 so that the relay body 5 is tilted relative to the assembly surface of the relay chassis 6 at a preset tilt angle. In another preferred embodiment, the slide of the Z-axis lifting assembly 312 is also provided with a material-picking finger cylinder 33. In this embodiment, the material-picking finger cylinder 33 on the robotic arm mechanism 3 transfers the relay body 5 from the material-picking fixture 4 to the body tilting positioning mechanism 1, thereby tilting and positioning the relay body 5 at a preset tilt angle on the body tilting positioning mechanism 1. Then, the assembly finger component 32 on the robotic arm mechanism 3 moves the tilted relay body 5, maintaining its original tilt angle, to the pre-assembly fixture 2 and pre-tightly assembles it with the relay chassis 6 at a preset tilt angle.
