[0002] The central armrest is an important part of the car interior, which is located between the driver's seat and the front passenger seat. The central armrest includes an armrest box and an armrest cover for sealing the armrest box. The armrest cover can also provide elbow support for the driver or front passenger to reduce arm fatigue caused by long-term driving.

[0003] The armrest cover is mostly made of plastic material. In order to improve comfort and aesthetics, the outside of the armrest cover is covered with an armrest leather. The material of the armrest leather is usually genuine leather, PVC artificial leather or PU. The production process of the armrest cover covered with the armrest leather is: cut out the armrest leather with the corresponding shape according to the armrest cover, and then spray a layer of glue on the outer edge of the armrest leather, and stick the armrest leather on the armrest cover. However, since the armrest leather is a flexible material, when spraying glue on its outer edge, part of the edge is often wrinkled and deformed, resulting in uneven glue spraying area, affecting the adhesion quality of the armrest leather on the armrest cover, and even affecting the aesthetics of the armrest cover. In severe cases, the armrest leather needs to be removed and re-covered, resulting in low production efficiency and product qualification rate of the armrest cover. Utility Model Content

[0025] Embodiment 1

[0026] like Figure 1-4 As shown, the utility model provides a glue spraying device for the surface of an automobile handrail, including a fixed platform 1, a fixed frame 2 is provided on the fixed platform 1, a movable unit is provided on the fixed frame 2, the movable unit includes an electric cylinder 3, a fixed end of the electric cylinder 3 is installed on the top of the fixed frame 2, and the upward and downward movement of the movable unit is realized by the electric cylinder 3.

[0027] The movable end of the electric cylinder 3 is connected to the pressing plate 4, and a connecting rod 19 is fixedly provided on the lower surface of the pressing plate 4, and the center line of the connecting rod 19 coincides with the center line of the electric cylinder 3. This can improve the overall stability of the mobile unit. When the electric cylinder 3 pushes the pressing plate 4 to move downward, most of the downward force can be applied to the connecting rod 19 to prevent the pressing plate 4 from being deformed by force. A downward pressing block 7 is provided at the bottom of the mobile unit, and the bottom of the connecting rod 19 is connected to the downward pressing block 7.

[0028] A mold unit is provided at a position on the fixed platform 1 corresponding to the lower pressing block 7, and the mold unit includes a fixed seat 9, which is arranged on the fixed platform 1, and a concave mold 8 is provided on the top of the fixed seat 9. The internal structure of the concave mold 8 is the same as the external shape of the armrest cover, and the bottom of the lower pressing block 7 is the same as the internal structure of the concave mold 8.

[0029] When using the device, the armrest skin can be placed inside the concave mold 8, and the concave mold 8 simulates the armrest cover. The electric cylinder 3 pushes the pressing block 7 downward, so that the armrest skin is pressed into the concave mold 8. At this time, the edge of the armrest skin can be fully stretched, thereby facilitating the subsequent glue spraying operation on the armrest skin.

[0030] A glue spraying unit is slidably mounted on the moving unit. The glue spraying unit includes an annular guide rail 5 . The annular guide rail 5 is arranged on the lower surface of the pressing plate 4 through a plurality of fixed pull rods 13 . A sliding block 16 matching the annular guide rail 5 is disposed on the annular guide rail 5 .

[0031] A glue spraying clamp 6 is provided at the bottom of the slider 16, and a nozzle 18 is fixed on the glue spraying clamp 6. The nozzle 18 can be fixed by adjusting the adjusting nut on the glue spraying clamp 6, so that multiple spraying angles can be achieved, which can meet the glue spraying requirements for the handrail surface of various sizes. The water-based environmentally friendly glue required on the handrail surface of the car can be sprayed from the nozzle 18. A sprocket chain assembly is provided on the inner side of the annular guide rail 5, and the sprocket chain assembly includes a driving sprocket 17 and a driven sprocket 11. The driving sprocket 17 and the driven sprocket 11 are fixed to the bottom side of the pressure plate 4 through a sprocket frame 10. An active motor 15 is provided on the sprocket frame 10 on one side of the driving sprocket 17, and the output shaft of the active motor 15 is connected to the rotating shaft of the driving sprocket 17.

[0032] The driving sprocket 17 and the driven sprocket 11 are provided with a transmission chain 12, and a connecting bar 14 is integrally provided on the inner side of the slider 16. The pin on the transmission chain 12 is fixedly connected to the connecting bar 14 by welding, and the connection between the two does not affect the normal operation of the transmission chain 12. The driving motor 15 can drive the driving sprocket 17 to rotate, and then drive the transmission chain 12 to rotate on the driving sprocket 17 and the driven sprocket 11.

[0033] Since the slider 16 is connected to the transmission chain 12 via the connecting bar 14, the rotation of the transmission chain 12 can drive the slider 16 to slide on the annular guide rail 5. While the slider 16 slides, the nozzle 18 can spray water-based environmentally friendly glue on the outer edge of the handrail surface. The other side of the nozzle 18 is connected to the glue spraying chamber via a glue spraying hose. The glue spraying chamber is provided with a glue spraying motor. The electronic control unit in the device is electrically connected to the glue spraying motor and the active motor respectively, so as to control the movement of the slider 16 and the glue spraying of the nozzle 18, so as to achieve uniform glue spraying on the handrail surface.

[0034] Therefore, the utility model adopts the above-mentioned automobile armrest skin glue spraying device, which can easily realize uniform glue spraying on the armrest skin, ensure the qualified rate of the product, and effectively improve the glue spraying efficiency.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
