Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of assembly test equipment, in particular to an automobile side door stay rod switch driving module assembly test equipment. BACKGROUND

[0002] With the continuous improvement of the intelligent level of automobiles, electric side sliding doors, electric tailgates and other configurations are increasingly popular, and the demand for automobile side door switch driving modules (hereinafter referred to as "driving modules") as their core executive mechanism is increasing. The driving module is usually composed of a motor assembly and a stay rod assembly, and the stay rod is driven to extend and retract by the motor, thereby realizing the opening and closing of the door.

[0003] The traditional driving module assembly and test process highly depends on manual operation, and there are many bottlenecks. First, in the assembly link, the stay rod needs to be smeared with lubricating grease at a specified section, and its length needs to be accurately measured to ensure the matching with different vehicle models. Manual oiling has the problems of poor consistency, grease waste and pollution, while manual measurement is inefficient and prone to errors. Second, when the motor assembly and the stay rod assembly are finally locked and assembled, multiple steps such as nut locking and end cover pressing need to be completed in sequence, and the assembly depth of the stay rod in the motor needs to be accurately adjusted. Manual operation cannot guarantee precision and efficiency, and there is a risk of missing or misassembling.

[0004] More importantly, the performance test link after assembly is crucial. The driving module needs to be tested for multiple tests including active running test (simulating normal work), passive running test (simulating manual operation) and transmission gap detection, to verify whether its output force, running stroke and meshing gap meet the stringent automotive safety and performance standards. The traditional test method mainly uses scattered and semi-automatic tooling, and the test process is complicated, and the data relies on manual interpretation, which not only is inefficient, but also the reliability and consistency of the test results are difficult to guarantee, and cannot meet the needs of large-scale automated production.

[0005] Therefore, the industry urgently needs a highly integrated and automated special-purpose equipment that can integrate the oiling, length measurement, precise assembly, multiple performance tests and air tightness tests of the driving module into one, realize the standardization, dataization and unmanned of the production process, and fundamentally improve product quality and production efficiency.

In order to meet the above three tests, the first test unit 3 of the embodiment comprises a second supporting seat 31 supporting a switch driving module, a second compression assembly 32 compressing and fixing the switch driving module on the second supporting seat 31, a load / power module 33 connected with the strut A end in the switch driving module on the second supporting seat 31 and driving the strut 2021 to act to perform passive testing or simulate a load when the strut 2021 actively acts, a gap detection module 34 detecting whether the assembly gap between the strut assembly 202 and the motor assembly 201 meets the design requirements, a second power socket 35 used for plugging and power-on with the wire harness connector 203, a second camera 36 located above the second supporting seat 31 and used for detecting whether there is a nut 204 on the switch driving module placed on the second supporting seat 31, a third camera 37 detecting whether the end cover 2023 on the switch driving module is correctly locked, and a second code scanner 38 located above the second supporting seat 31.

[0041] The second supporting seat 31 is provided with an end face limiting plate 311 limiting the end face of the motor assembly 201 close to the strut B end in the axial direction, and a profiled bearing groove (not marked in the figure) profiled with the main body of the motor assembly 201.

[0042] The load / power module 33 comprises an eighth driving member 331, a sixth support plate 332 driven by the eighth driving member 331 to move in the X direction, a fifth cylinder 333 fixed on the sixth support plate 332, a seventh support plate 334 driven by the fifth cylinder 333 to move in the X direction, a pressure sensor 335 for monitoring the force acting on the seventh support plate 334 in the X direction, an A-end limiting support block 336 fixed on the seventh support plate 334 and used for positioning the end of the strut A, a sixth cylinder 337 fixed on the seventh support plate 334, a locking rod 338 driven by the sixth cylinder 337 to extend into the A-end limiting support block 336 in the Y direction and to lock the end of the strut A by being inserted into the eye 2024 of the end of the strut A, and a second displacement sensor 339 for monitoring the displacement distance of the seventh support plate 334.

The passive push rod 3313 can be driven to move forward and reverse along the X direction by the eighth cylinder 343 and the ninth cylinder 344. The third displacement sensor 348 is driven by the tenth cylinder 347 to contact the passive push rod 3313, and monitors the displacement of the passive push rod 3313 when the passive push rod 3313 is driven to move by the first push plate 345 and the second push plate 346, thereby realizing automatic detection of the assembly gap between the support rod assembly 202 and the motor assembly 201.
