Abstract
Description
Technical Field
[0001] This invention relates to the field of housing assembly technology, and more particularly to an ECU housing assembly production line. Background Technology
[0002] With the rapid development of automotive electronics technology, the demand for ECUs (electronic control units) as core automotive control components continues to grow, placing higher demands on the automation level, production efficiency, and assembly precision of assembly lines.
[0003] Existing ECU housing assembly lines mostly adopt a traditional linear series layout, with each processing mechanism arranged along a single horizontal straight line. This has the following shortcomings: First, the linear layout requires a large workshop space, the working areas of adjacent mechanisms overlap, equipment interference is likely to occur, and space utilization is low, making it difficult to adapt to the site constraints of small and medium-sized workshops. Second, ECU housing assembly usually involves the coordinated assembly of at least two parts, such as a base and a cover plate. Existing production lines mostly use a single feeding mechanism with manual assistance, resulting in asynchronous feeding of the two parts and inconsistent flow rhythm, which seriously affects production efficiency. In addition, traditional assembly tooling mostly uses a single-direction clamping and positioning structure, which is insufficient for controlling the alignment and fitting accuracy of the two parts, making it easy for assembly deviations to occur, which in turn affects the sealing performance and structural stability of the ECU housing. At the same time, the transfer coordination design between the mechanisms is not perfect, and the transfer time between processes is long, which further reduces the overall automation level and continuous operation capability of the production line.
[0004] To address the aforementioned issues, the ECU housing assembly line urgently needs to be adapted to accommodate the simultaneous assembly of two components. Summary of the Invention
[0005] To address the issue of co-assembly of ECU housings, this application provides an ECU housing assembly production line. The ECU housing assembly production line provided in this application employs the following technical solution:
[0006] An ECU housing assembly production line includes a first feeding mechanism, a second feeding mechanism, and a screw fastening mechanism, an assembly mechanism, and an adhesive application mechanism arranged in a stepped series along the production flow direction. The screw fastening mechanism includes a first frame with a first linear guide rail and a first worktable slidably mounted on the first linear guide rail. The first frame also includes a third robotic arm for screw fastening and a fourth robotic arm for transfer operations. A first driving component for moving the first worktable is also provided on the first frame. The assembly mechanism includes a second frame with a second linear guide rail and a second worktable slidably mounted on the second linear guide rail. Assembly fixtures are mounted on the second worktable. A fifth robotic arm for transfer operations is also provided on the second frame. A second driving component for moving the second worktable is also provided on the second frame. The adhesive application mechanism includes a third frame with a third linear guide rail and a third worktable slidably mounted on the third linear guide rail. A sixth robotic arm for adhesive application is also provided on the third frame. The first and second feeding mechanisms are respectively located on one side of the screw fastening mechanism and the assembly mechanism.
[0007] Optionally, the first and second feeding mechanisms have the same structure, both including a feeding platform, a pre-processing station, and a feeding robotic arm for transfer.
[0008] Optionally, the assembly fixture has a positioning protrusion on one side and a hollow structure on the other three sides, and is equipped with a first cylinder, a second cylinder and a third cylinder. The third cylinder is arranged opposite to the positioning protrusion, and the first cylinder and the second cylinder are arranged opposite to each other on the other two sides.
[0009] Optionally, the first driving component includes a rodless cylinder, which is mounted on a first bracket, and the output end of the rodless cylinder is connected to the first worktable.
[0010] In summary, this application includes at least one of the following beneficial technical effects:
[0011] Two independent feeding mechanisms supply two parts to be assembled, and with the pre-positioning design of the robotic arm and the pre-processing station, parallel feeding and synchronous flow of two parts are achieved, shortening the assembly cycle and improving production efficiency. Each mechanism forms a complete automated flow link through the transfer of the robotic arm and the sliding of the worktable, which improves the continuous operation rate of the production line, reduces labor costs and reduces human error. The non-linear stepped series layout is adopted, with adjacent mechanisms staggered in the horizontal direction, which avoids equipment interference and does not rely on long straight-line space, thus improving the utilization rate of workshop space.

Figure 1 and Figure 2 The system includes a first feeding mechanism 1, a second feeding mechanism 2, and a screw fastening mechanism 3, an assembly mechanism 4, and an adhesive application mechanism 5 arranged in a stepped series along the production flow direction. The stepped series arrangement specifically means that adjacent mechanisms are staggered by a predetermined distance in the horizontal direction to avoid interference between processes and improve workshop space utilization. The screw fastening mechanism 3 includes a first frame, a first linear guide rail on the first frame, a first worktable 31 slidably mounted on the first linear guide rail, and a third robotic arm 32 for screw fastening operations and a transfer mechanism on the first frame. The fourth robotic arm 33 is used for the operation. The first frame also has a first driving component that moves the first worktable 31. The first driving component includes a rodless cylinder, the moving end of which is connected to the first worktable 31.

The fourth robotic arm 33 has a gripper at its execution end for gripping the processed workpiece. The assembly mechanism 4 includes a second frame, a second linear guide rail on the second frame, and a second worktable 41 slidably mounted on the second linear guide rail. The first frame is equipped with assembly fixtures. The second frame has a fifth robotic arm 42 for transfer operations, with a suction cup at its end. The second frame also has a second driving component to move the second worktable 41. The third driving component includes a first gear and a first rack meshing with the first gear, with the first rack mounted on the second frame. The second worktable 41 has a first motor, with the first gear located at the motor's output end. The glue-applying mechanism 5 includes a third frame with a third linear guide rail. A third worktable 51 slides on the third linear guide rail. The third frame also has a sixth robotic arm 52 for glue-applying operations, with a glue-applying head at its end.

Figure 3 The first feeding mechanism 1 and the second feeding mechanism 2 have the same structure, both including a feeding platform 11, a pre-processing station 12 and a feeding robotic arm 13 for transfer. The feeding robotic arm 13 transfers the parts on the feeding platform 11 to the pre-processing station 12 for pre-processing.

[0021] Reference Figure 4The assembly tooling has a positioning protrusion 411 on one side and a hollow structure on the other three sides.

The second feeding mechanism, with its feeding robotic arm 13, transfers part two to the assembly fixture on the second worktable 41. After the screw fastening mechanism 3 finishes processing the part on the first worktable 31, the second worktable 41 moves with part two closer to the screw fastening mechanism 3. The fourth robotic arm 33 transfers the part to the assembly fixture on the second worktable 41. Part one and part two are pre-assembled into a product on the assembly fixture. Then, the fifth robotic arm 42 transfers the product to the third worktable 51. The gluing mechanism 5 applies glue to the product. After processing is completed, the third worktable 51 continues to move downstream.
