[0002] Door trim panel clips are connecting parts used to fix the door trim panel to the door sheet metal. They are usually made of plastic and designed in a specific shape, such as a mushroom head. Through the elastic deformation or barbed structure of the clip, the trim panel is firmly clipped into the mounting holes or slots of the door sheet metal. This connection method does not require additional screws or bolts, and is relatively convenient for installation and disassembly, which can effectively improve assembly efficiency.
[0003] This also ensures the stability of the connection between the interior trim panel and the door, reducing abnormal noises caused by vibration during driving. For example, during car repairs or interior trim panel replacement, repair personnel only need to use special tools or appropriate force to pull out or push in the clips from their installation positions, thus enabling the removal and installation of the interior trim panel.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1-4 An embodiment of this utility model provides a door interior panel snap-fit assembly device, including a base plate 1, a base box 2 fixedly installed on the top of the base plate 1, a rotating seat 3 rotatably installed on the top of the base box 2, a lifting mechanism 4 provided above the rotating seat 3, a translation mechanism 5 provided above the lifting mechanism 4, a vertical plate 6 provided on one side of the translation mechanism 5, an mounting plate 7 fixedly installed below one side of the vertical plate 6, a rotating column 901 rotatably installed below the mounting plate 7, a circular frame 9 fixedly installed below the rotating column 901, an electric gripper 10 fixedly installed on one side below the circular frame 9, a pressure plate 11 provided on the other side below the circular frame 9, a pressure electric cylinder 12 fixedly installed inside the circular frame 9, and the push rod end of the pressure electric cylinder 12 slidably extends to the bottom of the circular frame 9 and is fixedly connected to the pressure plate 11.
[0024] During the assembly of the door interior panel clips, the electric gripper 10 facilitates automatic gripping of the clips, and the lifting mechanism 4, translation mechanism 5 and rotating seat 3 facilitate the movement of the clips to the top of the door tooling for assembly. The pressure plate 11 and pressure electric cylinder 12 facilitate the pressing of the clips, so that the clips are stably placed into the mounting holes of the door interior panel.
[0025] Please see Figure 3 The lifting mechanism 4 includes a square tube 401, a square column 402, and a lifting electric cylinder 403. The lower end of the square tube 401 is fixedly connected to the rotating seat 3. The square column 402 is located above the square tube 401, and the lower end of the square column 402 slides into the interior of the square tube 401. The lifting electric cylinder 403 is located inside the square tube 401, and the lower end of the lifting electric cylinder 403 is fixedly connected to the rotating seat 3. The push rod end of the lifting electric cylinder 403 is fixedly connected to the square column 402.
[0026] The cooperative structure of the square tube 401 and the square column 402 provides a stable guide for the lifting process, ensuring that the square column 402 can move smoothly up and down under the push of the lifting electric cylinder 403, avoiding swaying and deviation, and improving the accuracy and stability of lifting. Through the setting of the lifting electric cylinder 403, the lifting height can be precisely adjusted according to the installation height requirements of different door interior panel clips, meeting diverse assembly needs and improving the versatility and adaptability of the device.
[0027] Please see Figure 1 The translation mechanism 5 includes a platform 501, a fixed plate 502, and a translation electric cylinder 503. The platform 501 is fixedly installed above the square column 402, the fixed plate 502 is fixedly installed above the platform 501, and the translation electric cylinder 503 is fixedly installed on one side of the fixed plate 502. The push rod end of the translation electric cylinder 503 slides through the fixed plate 502 and is fixedly connected to the vertical plate 6.
[0028] The electric cylinder 503 enables translational drive, allowing for easy adjustment of the position of the vertical plate 6 according to assembly requirements. This, in turn, drives components such as the electric gripper 10 and the pressure plate 11 to move accurately to the target position, increasing practicality.
[0029] Please see Figure 4 Stabilizing guide plates 14 are symmetrically fixedly installed on the front and rear ends of one side of the upright plate 6. Fixing sleeves 15 are symmetrically fixedly installed on the top of the front and rear ends of the square column 402. One end of the stabilizing guide plate 14 slides through the fixing sleeve 15.
[0030] The cooperation between the stabilizing guide plate 14 and the fixing sleeve 15 provides additional guiding support for the movement of the upright plate 6, making the upright plate 6 more stable during translation, reducing assembly errors caused by shaking or offset, and improving assembly accuracy.
[0031] Please see Figure 4 Reinforcing plates 16 are symmetrically fixedly installed on the upper sides of the square column 402, and the reinforcing plates 16 are fixedly connected to the platform 501.
[0032] The symmetrical installation of the reinforcing plate 16 effectively enhances the connection strength between the square column 402 and the platform 501, making the entire structure more stable and able to withstand greater loads and moments. This avoids structural deformation or damage caused by excessive force during assembly, and improves the reliability and stability of the device.
[0033] Please see Figure 3 The bottom box 2 has a motor 13 fixedly installed inside. The output shaft of the motor 13 is fixedly connected to the rotating seat 3. The motor 13 is a servo motor with self-locking capability.
[0034] This allows the electric motor 13 to drive the rotating seat 3 to rotate, which is beneficial for the assembly of the snap fastener.
[0035] Please see Figure 2 A motor 8 is fixedly installed on the top of the mounting plate 7. The output shaft end of the motor 8 is fixedly connected to the rotating column 901. The motor 8 is a servo motor with self-locking capability.
[0036] The motor 8 is designed to drive the rotating frame 9, which facilitates the assembly of the snap-fit and increases its practicality.
[0037] Working principle: In use, the door interior panel clip assembly device is installed on one side of the door assembly line, and a vibratory feeder is set on one side of the device for clip feeding. During the door interior panel clip assembly process, the electric gripper 10 automatically grabs the clip. Subsequently, the lifting electric cylinder 403 pushes the square column 402 to move smoothly up and down in the square tube 401 according to the installation height requirements of different door interior panel clips, realizing the precise lifting of the lifting mechanism 4. The push rod end of the translation electric cylinder 503 pushes the upright plate 6, driving the electric gripper 10 and the pressure plate 11 and other components to move accurately on the platform 501. At the same time, the second motor 13 drives the rotating seat 3 to rotate, and the first motor 1... The drive column 901 rotates, which in turn drives the return frame 9 and its components such as the electric gripper 10 and the pressure plate 11 to rotate. Through the coordinated operation of the lifting mechanism 4, the translation mechanism 5, the rotating seat 3 and the drive column 901, the gripped buckle is precisely moved to the top of the door fixture. After reaching the designated position, the electric gripper 10 places the buckle into the mounting hole on the car interior panel. Then, the return frame 9 is rotated so that the pressure plate 11 faces the buckle. The push rod end of the pressure electric cylinder 12 pushes the pressure plate 11 downward, pressing the buckle stably into the mounting hole of the car interior panel, completing the assembly of the car interior panel buckle, reducing labor costs and increasing practicality.
