[0024] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0025] 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.

[0026] like Figures 1 to 6 As shown, this embodiment provides an automotive seat headrest assembly line, including: a first transmission belt for conveying automotive seat headrests 6; a feeding station 2 located at the end of the first transmission belt, wherein a second conveyor belt 201 parallel to the first transmission belt is provided on the feeding station 2; a fixing device is also provided on the feeding station 2 for fixing the automotive seat headrest 6 to the feeding station 2; and a first sensor 205 located on the feeding station 2 for detecting the presence of the automotive seat headrest 6 on the feeding station 2 and controlling the movement of the second conveyor belt 201 and the fixing device.

[0027] The feeding station 2 is a component separately arranged at the end of the first transmission belt, and there is no mechanical connection between the two. The feeding station 2 is divided into a second transmission belt 201 to separate the transmission and positioning functions, reduce the interference such as shaking and displacement of the remaining processes, so that the first transmission belt 1 bears the function of transmitting the automobile seat headrest 6, and the feeding station 2 bears the function of positioning and fixing the automobile seat headrest 6, so as to facilitate the robot to grasp the automobile seat headrest 6, and the feeding accuracy of the automobile seat headrest 6 is preliminarily improved. The first sensor 205 is properly arranged, so that when the first sensor 205 detects that the feeding station 2 has the automobile seat headrest 6, the second transmission belt 201 is controlled to stop working, and the headrest 6 is basically in the working area of the fixing device. When the first sensor 205 detects the headrest 6, the second transmission belt is controlled to stop working, the fixing device acts to fix the headrest 6 on the feeding station 2, so as to avoid the position of the headrest 6 changing when the robot grasps the headrest 6, thereby improving the feeding accuracy of the headrest 6 and the accuracy of the robot grasping the headrest 6.

[0028] In a possible embodiment, the fixing device comprises a fixing member 202 and a pushing member. The fixing member 202 is arranged at one side of the feeding station 2 of the second transmission belt 201, and the pushing member is arranged at the other side of the feeding station 2 of the second transmission belt 201 and opposite to the fixing member 202. The pushing member is used to push the automobile seat headrest 6 to the fixing member 202, and cooperate with the fixing member 202 to fix the automobile seat headrest 6.

[0029] The fixing member 202 and the pushing member are arranged at two sides of the second transmission belt 201. When the automobile seat headrest 6 is sent by the second transmission belt 201 and receives the signal of the first sensor 205, the pushing member acts to push the headrest 6 to the fixing member 202, so that the headrest 6 abuts against the fixing member 202, and the pushing member remains stationary until the robot successfully grasps the guide rod of the headrest 6. The above operation of fixing the headrest 6 avoids the headrest 6 being disturbed by the robot and external interference, avoids the position of the guide rod of the headrest 6 being wrong when the robot grasps the guide rod, and greatly improves the accuracy of the robot grasping the headrest 6.

[0030] Further, the feeding member comprises a pushing cylinder 203 arranged on the feeding station 2 and a pushing plate 204 connected with the pushing cylinder 203. The pushing cylinder 203 is arranged at one side of the feeding station 2, the pushing plate 204 is fixedly connected with the execution end of the pushing cylinder 203, and the pushing cylinder 203 drives the pushing plate 204 from a track parallel to the second transmission belt 201, so that the pushing plate 204 and the fixing member 202 can stably fix the automobile seat headrest 6.

[0031] In a possible embodiment, the first transmission belt end is provided with a second sensor 101, which detects the presence of the headrest 6 of the car seat on the first conveying belt 1 and controls the start and stop of the first transmission belt. After the first transmission belt sends the headrest 6 to the second conveying belt 201, the first conveying belt 1 will continue to send the next headrest 6 forward. In order to avoid the situation that the next headrest 6 is sent to the feeding station 2 while the previous headrest 6 has not been grabbed by the robot, when the second sensor 101 detects the presence of the end of the first conveying belt 1, the first sensor 205 sends a signal to stop the first conveying belt 1 until there is no headrest 6 in the feeding station 2, and then the system starts the first conveying belt 1 to convey the headrest 6 to the feeding station 2.

[0032] In a possible embodiment, the feeding station 2 is also provided with a lifting cylinder 301, and the execution end of the lifting cylinder 301 is connected with a lifting plate 302 for lifting the guide rod of the headrest 6 of the car seat. The guide rod of the headrest 6 on one side of the headrest 6 is longer, so the headrest 6 may tilt to the side where the guide rod is located during conveying, which affects the feeding accuracy of the headrest 6 and the grabbing of the robot. Therefore, the lifting cylinder 301 and the lifting plate 302 are arranged on the feeding station 2 on the side of the guide rod of the headrest 6, and before the action of the fixing device each time, the lifting cylinder 301 drives the lifting plate 302 to move upward to lift the guide rod of the headrest 6 in the abnormal position, so as to facilitate the fixing device to fix the headrest 6.

[0033] Further, the lifting plate 302 is provided with a groove 303 matched with the guide rod of the headrest 6 of the car seat. The top of the groove 303 should also be provided with a beveled structure to guide the guide rod of the headrest 6 to the groove 303; the size of the groove 303 is slightly larger than that of the guide rod of the headrest 6, which can avoid the sliding dislocation of the guide rod when the lifting plate 302 lifts the guide rod of the headrest 6.

[0034] Further, the end of the lifting plate 302 close to the first conveying belt 1 is bent downward. It prevents the headrest 6 from being stuck by the lifting plate 302 when being transported by the second conveying belt 201.

[0035] In a possible embodiment, the first transmission belt is provided with guide rods 102 on both sides. The guide rods 102 arranged on both sides of the second conveying belt 201 can guide and protect the headrest 6, preventing the headrest 6 from falling. Meanwhile, the two ends of the guide rods 102 are bent outward to avoid the end of the guide rod 102 from hooking the headrest 6.

[0036] In a possible embodiment, the end of the second conveying belt 201 is provided with a drop prevention baffle 4, and the bottom of the drop prevention baffle 4 is also inwardly hooked, which is used in case of accidental control of the second transmission belt, causing the headrest 6 to fall off the second conveying belt 201.

[0037] In a possible embodiment, one side of the feeding station is provided with an oil box 5 for lubricating the guide rod of the headrest 6 of the automobile seat.

[0038] The above merely illustrates the implementation modes of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made by the skilled in the art without creative labor within the spirit and principle of the present application shall be included in the protection scope of the present application.
