Description

Technical Field

[0001] This utility model relates to the field of automotive parts assembly technology, and more specifically, to an assembly and testing device for automotive headrests with a horn. Background Technology

[0002] The purpose of car headrests is to protect the vulnerable neck. When a car is involved in a rear-end collision, the headrest can cushion the impact on the head. Without a headrest, the force of the impact would directly compress the vulnerable neck, causing damage to the spine, and in severe cases, even paralysis or death. However, with the advancement of technology, car headrests are no longer just for protecting the necks of occupants. Some car headrests are equipped with speakers that transmit audio signals, allowing passengers to enjoy better music and sound effects, thus improving the overall driving and riding experience.

[0003] Currently, the production of car headrests with horns requires assembly equipment. This equipment can quickly assemble the headrest and horn. The assembled horn is then used inside the headrest via a signal transmission line. However, because car headrests are frequently touched by the heads of people inside the car, the signal transmission line on the horn is prone to detachment under external force. Existing assembly equipment cannot determine the connection strength of the signal transmission line after the horn is assembled, thus failing to guarantee the connection effect of the horn's signal transmission line inside the headrest. Utility Model Content

[0026] Example:

[0027] Please see Figure 1-4 A car headrest assembly and testing device with a horn includes a frame 1, a bearing assembly 2 fixedly connected inside the frame 1, a horn assembly seat 3 fixedly connected to the bearing assembly 2, a corner-down cylinder module 4 fixedly connected to the horn assembly seat 3, a servo motor 5 fixedly connected inside the frame 1, with the output end of the servo motor 5 fixedly connected to one end of the bearing assembly 2, a telescopic placement frame 6 fixedly connected inside the frame 1, an electric screw gun 7 detachably connected to the telescopic placement frame 6, a fixed base 8 fixedly connected inside the frame 1, a telescopic cylinder 9 fixedly connected to the fixed base 8, a sliding frame 10 fixedly connected to the output end of the telescopic cylinder 9, and the sliding frame 10 slidably connected to the fixed base 8. On the base 8, two electric telescopic rods 11 are fixedly connected to the slide frame 10. The output ends of the two electric telescopic rods 11 are equipped with spring gripper cylinders 12, and the two spring gripper cylinders 12 are corresponding to the horn assembly base 3. The two spring gripper cylinders 12 are equipped with tension sensors 13. The rear cover assembly base 14 and the fixing frame 15 are fixedly connected inside the frame 1. The rear cover assembly base 14 is fixedly connected with a positioning cylinder 23. The fixing frame 15 is fixedly connected with a pressing cylinder module 16. The output end of the pressing cylinder module 16 is fixedly connected with a snap-on upper mold base 17, and the snap-on upper mold base 17 is slidably connected to the fixing frame 15 and corresponds to the rear cover assembly base 14.

[0028] In this embodiment, when assembling the horn inside the car headrest, the car headrest is placed inside the horn assembly seat 3, and the corner-pressing cylinder module 4 presses down on the car headrest to position it, keeping the car headrest stable. The horn is placed inside the car headrest, and the telescopic placement frame 6 is used to place the electric screwdriver 7 for easy access by the operator. After the horn is placed inside the car headrest, the operator removes the electric screwdriver 7 from the telescopic placement frame 6 and uses the electric screwdriver 7 to screw the screw through the horn into the car headrest. The horn is then assembled inside the car headrest. During the screwing process, the servo motor 5 controls the bearing assembly 2 to rotate the horn assembly seat 3, adjusting the angle of the car headrest inside the horn assembly seat 3. This allows the operator to hold the electric screwdriver 7 and vertically screw the screw into the car headrest to fix the horn. After the car headrest and horn are assembled, the telescopic cylinder 9 pushes the sliding frame 10 forward on the fixed seat 8, causing the two spring-loaded gripper cylinders 12 to engage with the car headrest inside the horn assembly seat 3. Correspondingly, two electric telescopic rods 11 control two spring-loaded clamp cylinders 12 to extend downwards and clamp the signal transmission line on the horn. Then, they control the two spring-loaded clamp cylinders 12 to move upwards. During the upward movement of the two spring-loaded clamp cylinders 12, two tension sensors 13 perform a pull-out test on the signal transmission line to determine the connection effect of the horn signal transmission line. After the horn signal transmission line test is completed, the corner depressor cylinder module 4 resets to allow the car headrest to be unrestricted. Then, the headrest back cover is placed in the back cover assembly seat 14. Positioning cylinder 23 presses and fixes the headrest back cover from one side, making the headrest back cover stable in the back cover assembly seat 14 and corresponding to the buckle upper mold seat 17. The worker inserts the buckle into the buckle upper mold seat 17, and the pressing cylinder module 16 controls the buckle upper mold seat 17 to slide down on the fixing frame 15, so that the buckle upper mold seat 17 presses the buckle into the headrest back cover. The worker takes out the car headrest from the horn assembly seat 3 and uses the buckle to assemble it with the headrest back cover, protecting the horn and signal transmission line inside.

[0029] Specifically, a sensor 18 is fixedly connected inside the frame 1, and the same sensor 18 is fixedly connected on the rear cover assembly 14, with the two sensors 18 corresponding to the speaker assembly 3 and the rear cover assembly 14 respectively.

[0030] In this embodiment, two sensors 18 are used to detect the car headrest and headrest back cover, respectively, to determine the presence or absence of products in the speaker assembly 3 and the back cover assembly 14.

[0031] Specifically, a vision inspection camera 19 is fixedly connected to the top wall of the rack 1, and the vision inspection camera 19 corresponds to the speaker assembly base 3.

[0032] In this embodiment, the visual inspection camera 19 is used to visually inspect the car headrest to confirm whether a speaker is installed inside the headrest.

[0033] Specifically, guide rail assemblies 20 are fixedly connected to both the slide frame 10 and the fixing frame 15, and the fixing seat 8 and the snap-on upper mold base 17 are slidably connected to the two guide rail assemblies 20 respectively.

[0034] In this embodiment, the sliding frame 10 slides on the fixed base 8 by driving the guide rail assembly 20. The guide rail assembly 20 keeps the sliding frame 10 stable when moving back and forth. The upper mold base 17 of the snap fastener slides on the fixed frame 15 through the guide rail assembly 20. The guide rail assembly 20 keeps the upper mold base 17 of the snap fastener stable when moving down to press the snap fastener.

[0035] Specifically, a limiting block assembly 21 is fixedly connected inside the frame 1, and the limiting block assembly 21 is located on the lower side of the speaker assembly base 3.

[0036] In this embodiment, the limiting block assembly 21 is used to limit the bottom of the speaker assembly base 3 to prevent the speaker assembly base 3 from rotating excessively and affecting the operator's screw driving.

[0037] Specifically, a grating module 22 is fixedly connected to the front opening of the frame 1, and the grating module 22 corresponds to the speaker assembly base 3 and the rear cover assembly base 14.

[0038] In this embodiment, the grating module 22 is used to protect the staff and prevent them from sticking their arms into the equipment during operation, which would cause interference.

[0039] Working Principle: When assembling the horn inside the car headrest, first place the car headrest in the horn assembly seat 3. The rotating and pressing cylinder module 4 rotates and presses down to position the car headrest, fixing it in place within the horn assembly seat 3. Then, place the horn inside the car headrest. The operator removes the electric screwdriver 7 from the telescopic placement frame 6. The servo motor 5 controls the rotation of the horn assembly seat 3 via the bearing assembly 2, adjusting the angle of the threaded hole on the car headrest. This allows the operator to use the electric screwdriver 7 to screw the screw through the horn into the car headrest, completing the horn assembly inside the car headrest. After the car headrest and horn are assembled, the telescopic cylinder 9 pushes the sliding frame 10 forward on the fixed seat 8, aligning the two spring-loaded gripper cylinders 12 with the car headrest inside the horn assembly seat 3. The two electric telescopic rods 11 control the two spring-loaded gripper cylinders 12 to extend downwards, using the two spring-loaded gripper cylinders 12 to clamp the signal transmission line on the horn. The two electric telescopic rods 11 control the two spring-loaded gripper cylinders 12 to move upwards and pull the signal transmission line on the horn. During the pulling process, the two tension sensors 13 test the connection strength of the signal transmission line to determine the connection effect of the horn signal transmission line. After the horn signal transmission line test is completed, the corner pressing cylinder module 4 resets to allow the car headrest to be unrestricted and easily removed by the staff. The headrest back cover is placed in the back cover assembly seat 14, and the positioning cylinder 23 presses and fixes the headrest back cover from one side, so that the headrest back cover is stable in the back cover assembly seat 14 and corresponds to the buckle upper mold seat 17. The buckle is installed in the buckle upper mold seat 17, and the pressing cylinder module 16 controls the buckle upper mold seat 17 to slide and move downwards on the fixing frame 15, so that the buckle upper mold seat 17 presses the buckle into the headrest back cover. The staff takes out the car headrest from the horn assembly seat 3 and uses the buckle to assemble it with the headrest back cover, protecting the horn and signal transmission line inside.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
