Description

Technical Field

[0001] This utility model belongs to the field of automotive sunroof assembly technology, and in particular relates to a precise guiding and flexible motion mechanism for automotive sunroof assembly. Background Technology

[0002] In the automotive manufacturing industry, with the continuous upgrading of car brands, higher design requirements have been placed on sunroof systems. This has led to many inconvenient processes in the design, making it difficult for production line workers to operate and resulting in complex tooling designs that are difficult to operate and adjust. Current technology uses tooling to grip parts, which move back and forth under the drive of an electric cylinder. However, the parts are manually pushed in and out of the tooling. Frequent manual pushing and pulling of parts leads to high worker fatigue under full load and can easily damage parts, resulting in cost waste. Furthermore, ensuring consistent pushing positions on both sides and synchronous movements places high demands on operators and maintenance personnel. The complex tooling structure also significantly increases hardware investment and maintenance costs. Reliance on manual synchronous operation is also prone to assembly errors.

[0003] Therefore, there is an urgent need for a new technical solution to address this problem. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a precise guiding and flexible motion mechanism for the assembly of automotive sunroofs, in order to solve the problems of excessive reliance on manual labor, complex tooling adjustments, and high equipment maintenance costs in the existing technology.

[0005] The technical solution adopted by this utility model is to provide a precision guidance and flexible motion mechanism for the assembly of automotive sunroofs, including a device frame, a guide rail connecting plate fixed on the upper surface of the device frame, guide rails respectively provided on the guide rail connecting plate, and parts moving along the guide rails under the guidance of the guiding mechanism. The guiding mechanism is electrically connected to a PLC control system.

[0006] The guiding mechanism includes a servo motor, which is mounted on the drive base plate via a motor mounting bracket. The drive base plate is fixedly connected to the guide rail connecting plate. The servo motor drives a flexible shaft to move along the guide groove, and the flexible shaft drives the parts to move along the guide rail.

[0007] The PLC control system is used to control the motion parameters of the servo motor, enabling precise guidance and flexible movement of the parts.

[0008] The flexible shaft is connected to the handle of the part, enabling the part to move back and forth, simulating the actual movement trajectory of the sunroof.

[0009] The PLC control system adjusts the displacement, speed, and acceleration parameters of the servo motor through a preset program to adapt to the assembly requirements of different sunroof models.

[0010] The flexible shaft has a flexible structure and is made of spring steel wire wound around it.

[0011] Through the above design scheme, this utility model can bring the following beneficial effects:

[0012] 1. By setting up a servo drive system, the servo motor drives the flexible shaft to move the parts along the guide groove, replacing the traditional electric cylinder tooling, reducing manual labor intensity, eliminating the need for manual pushing and pulling of parts, reducing fatigue and operational errors, and solving the problems of low positioning accuracy, cumbersome adjustment and high technical requirements for adjustment personnel in traditional assembly processes.

[0013] 2. By setting up guide rails and guide rail connecting plates in combination, motion stability is ensured.

[0014] 3. By controlling the servo motor parameters through a preset program, multi-position adaptive adjustment can be achieved.

[0015] 4. Easy to maintain; modular design supports quick adjustments, greatly reducing maintenance costs. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1-2 As shown, this utility model discloses a precision guiding and flexible motion mechanism for automotive sunroof assembly, comprising a device frame 2, a guide rail connecting plate 3 fixed on the upper surface of the device frame 2, and guide rails 4 respectively provided on the guide rail connecting plate 3. Parts 5 move along the guide rails 4 under the guidance of the guiding mechanism 1. The guiding mechanism 1 is electrically connected to a PLC control system. Under the control of the PLC program, the guiding mechanism 1 can achieve precise control of its movement position and can accurately adjust to different positions.

[0021] The guiding mechanism 1 includes a servo motor 101, which is mounted on a drive base plate 103 via a motor mounting bracket 102. The drive base plate 103 is fixedly connected to the guide rail connecting plate 3. The servo motor 101 drives a flexible shaft 105 to move along a guide groove 104, and the flexible shaft 105 drives the part 5 to move along the guide rail 4. The flexible shaft 105 is connected to the part handle 106 to realize the forward and backward movement of the part 5, simulating the actual movement trajectory of the sunroof.

[0022] The PLC control system is used to control the motion parameters of the servo motor 101, enabling precise guidance and flexible movement of part 5. The PLC control system adjusts the displacement, speed, and acceleration parameters of the servo motor 101 through preset programs to adapt to the assembly requirements of different sunroof models.

[0023] The flexible shaft 105 has a flexible structure, is made of spring steel wire, has high rigidity, is not easily deformed, and its length can be adjusted according to different products.

[0024] Example: This mechanism was applied to the sunshade assembly line of the VW336 model. Specific parameters are as follows:

[0025] Servo motor: rated power 0.75kW, repeatability ±0.5mm;

[0026] Flexible shaft: made of spring steel, 4.7mm in diameter, and adjustable in length;

[0027] PLC program: 3 preset motion modes to adapt to different sunroof models.

[0028] This invention employs a servo motor 101 to drive the flexible shaft 105, replacing the traditional electric cylinder that drives the tooling guide. This simulates the actual movement of the product, avoiding errors caused by machining and adjustment, and resulting in more precise positioning. Using original parts for the drive process reduces the need for manual pushing and pulling of components, thus reducing operator fatigue. It also avoids adjustment errors caused by manual equipment maintenance. The entire process is controlled by a PLC; position adjustment and control are automated, reducing frequent manual operation, minimizing assembly errors, and improving product quality and efficiency.

[0029] The PLC control system can adjust motion parameters in real time through system programming to meet different product requirements and ensure assembly accuracy. PLC control programs are already very mature and utilize existing technology; therefore, this invention will not elaborate on the specific application of this technology in tooling operation.

[0030] The embodiments of this utility model have been described above, but they should not be construed as limiting the claims. This utility model is not limited to the above embodiments, and its specific structure is allowed to vary. All changes made within the scope of protection of the claims of this utility model are within the scope of protection of this utility model.
