[0016] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0017] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0018] like Figures 1 to 3 As shown, this embodiment provides a car seat headrest assembly fixture with opposing "chopstick"-shaped gripping fingers 3. On the inner side of each gripping finger 3, i.e., on the opposite side of the two gripping fingers 3, grooves 303 adapted to fit the guide rod 701 of the car seat headrest 7 are provided. The two opposing grooves 303 are used to grip the car seat headrest 7. The fixture includes a base 1, on which gripping mechanisms are symmetrically arranged. The gripping mechanism includes a drive member 2 and grippers. The drive member 2 is mounted on the base 1, and the grippers are connected to the actuating end of the drive member 2. Each gripper includes two opposing gripping fingers 3, and on the opposite side of each gripping finger 3, grooves 303 adapted to fit the guide rod 701 of the car seat headrest 7 are provided. The drive member 2 drives the two gripping fingers 3 of the gripper to move closer or further apart, so that the gripper grips or releases the guide rod 701 of the car seat headrest 7.

[0019] like Figure 1-3 As shown, in this embodiment, the two ends of the base 1 are symmetrically arranged gripping mechanisms for gripping the guide rod 701 of the car seat headrest 7. The drive component 2 of the gripping mechanism is fixedly installed on the base 1, and the gripper is fixedly connected to the execution end of the drive component 2, so that the gripper can be controlled by the drive component 2 to grip or release the gripping action. In order to better grip the guide rod 701 of the headrest 7, the gripper has two fingers that, when closed, will tightly clamp the guide rod 701 of the headrest 7. Compared with direct gripping, this gripping method can avoid the headrest 7 from rotating along the contact point between the gripper fingers 3 and the guide rod 701 due to its own gravity when gripping the guide rod 701. In this way, by controlling the two gripper fingers 3 of the gripper to move closer or further apart, the guide rod 701 of the car seat headrest 7 can be gripped or released, thus completing the gripping or placement of the car seat headrest 7.

[0020] In one possible implementation, the gripper finger 3 includes a connecting portion 301 and a finger tip 302. The connecting portion 301 is used to connect to the drive member 2, and the finger tip 302 is used to grip or release the guide rod 701 of the car seat headrest 7. The connecting portion 301 has multiple through holes, through which bolts are passed for tight connection to the actuating end of the drive member 2, providing support for the finger tip 302. The finger tip 302 is located inside the connecting portion 301 to facilitate gripping the guide rod 701 of the headrest 7.

[0021] In one possible implementation, the groove 303 is a V-shaped groove. The V-shaped groove has two contact points with the guide rod 701 of the circular headrest 7. In the clamping state, the two V-shaped grooves have a total of four contact points with the guide rod 701 of the headrest 7, which greatly improves the stability of clamping.

[0022] In one possible implementation, the drive component 2 is a pneumatic finger, and the two gripping fingers 3 of the gripper are respectively connected to the actuating end of the pneumatic finger. The bottom of the pneumatic finger is fixedly connected to the base 1, and the actuating end of the pneumatic finger can simultaneously close and open, which fits well with the gripper in this embodiment. The connecting part 301 of the gripping finger 3 is fixedly connected to the actuating end of the pneumatic finger, so the movement of the gripping finger 3 can be controlled by the pneumatic finger.

[0023] In one possible implementation, the base 1 is also provided with a protective baffle 4 extending in a direction perpendicular to the movement trajectory of the finger clip 3, that is, extending along the length direction of the car seat headrest 7; after the length of the protective baffle 4 exceeds the headrest 7, the end of the protective baffle 4 bends toward the finger clip 3 side to protect the main body and top of the headrest 7 from being bumped.

[0024] The automotive seat headrest 7 assembly fixture based on the above embodiments, such as Figure 4-6 As shown, this embodiment also provides an automatic assembly device for a car seat headrest 7, including a robot 5, on which a car seat headrest 7 assembly fixture as described in any of the above embodiments is mounted.

[0025] In one possible implementation, the base 1 is further provided with a connecting seat 8, which has connecting pins 801. The car seat headrest 7 assembly fixture is connected to the robot 5 via the connecting pins 801. On the side of the base 1 opposite to the gripper mechanism, a circular connecting seat 8 is provided, with four upward-extending connecting pins 801 on the connecting seat 8. During installation, the four connecting pins 801 on the connecting seat 8 are inserted into the end effector of the robot 5, allowing the robot 5 to control the rotation and movement of the base 1 and its related components.

[0026] In one possible implementation, the robot 5 is equipped with a vision detection device 6, which identifies the guide rod 701 of the car seat headrest 7. The vision detection device 6 is connected to the control center of the robot 5. After the control center is configured, the robot 5 controls the gripper to reach the headrest 7 gripping position, identifies the guide rod 701 of the car seat headrest 7 through the vision detection device 6, and grips the guide rod 701 of the car seat headrest 7 to complete the gripping action. During installation, the vision detection device can also identify the mounting holes on the car seat to facilitate the robot 5 controlling the gripper to insert the guide rod 701 of the headrest 7 into the mounting holes.

[0027] In one possible implementation, the robot 5 is equipped with a force sensor to detect the force applied to the guide rod 701 of the car seat headrest 7 during installation. During installation, the robot 5 aligns the guide rod 701 of the headrest 7 with the seat and presses it down. When the car seat makes a click, the headrest 7 is installed. However, the damping and installation stroke in this process are not fixed. Therefore, by detecting changes in the force applied by the robot 5 to the guide rod 701 of the headrest 7 through the force sensor, and sensing changes in the resistance experienced by the headrest 7, the robot 5 can determine whether the headrest 7 is installed correctly.

[0028] Workflow During the gripping process, robot 5 controls the gripper to move to the picking position. The vision detection device 6 identifies the position of the headrest 7 and its guide rod 701. Robot 5 then controls the gripper fingers 3 to open, aligning the opening and V-groove of the gripper fingers 3 with the guide rod 701 of the headrest 7. Finally, robot 5 controls the gripper fingers 3 to close, completing the gripping process. After gripping, robot 5 can control the headrest 7 to apply lubricant.

[0029] During installation, robot 5 controls the fixture and headrest 7 to move to the car seat position. The vision detection device 6 identifies the mounting holes of the car seat, aligns the guide rod 701 of the headrest 7 with the mounting holes and inserts it downwards. When the force sensor detects a sudden and significant change in resistance, the installation is complete.

[0030] The above description is merely illustrative of the embodiments of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model without creative labor should be included within the protection scope of this utility model.
