[0001] The utility model relates to the technical field of sound insulation cotton pasting, in particular to a pasting and positioning device for sound insulation cotton. Background Technique

[0002] The control of vehicle noise is an important part in the process of vehicle design and manufacturing. The size of vehicle noise will directly affect the user experience. Vehicle noise comes from multiple aspects, such as: engine, transmission, drive axle, drive shaft, carriage, glass window, tire, relay, horn, audio, etc. These parts will generate noise during operation. The sound insulation cotton can absorb and convert the noise vibration energy, so as to achieve the effect of sound absorption and noise reduction. Therefore, the sound insulation cotton is widely used in the automotive manufacturing industry.

[0003] At present, the fixing process of the sound insulation cotton on the vehicle body is the back glue pasting process. A back glue is installed on one side of the sound insulation cotton. During the pasting process, due to the different winding methods of the rubber roller and the sound insulation cotton, and the position of the rubber strip cannot be adjusted, there is a deviation between the rubber strip and the sound insulation cotton, which affects the finished product effect. The rubber roller shaft is easy to fall off from the roller frame, affecting the actual use, and the rubber roller shaft cannot realize the driven gluing action. Therefore, a pasting and positioning device for sound insulation cotton is proposed for the above problems. Content of the Utility Model

[0021] A glue pasting and positioning device for sound insulation cotton, including a material rack 1, a fixing plate 3, a rubber roller shaft 9 and an adjustment base 12. At the bottom of both ends of the material rack 1, there are fixedly connected brackets 2. On the front side of the left bracket 2, there is fixedly connected a fixing plate 3. On one side of the fixing plate 3, there is fixedly connected a support plate 4. On one side of the support plate 4, there is fixedly connected a clutch 5. On one side of the clutch 5, there is fixedly connected a motor 6, and the output end of the motor 6 is fixedly connected to the input end of the clutch 5. The output end of the clutch 5 is fixedly connected to a first gear 7. The first gear 7 is meshed with a second gear 8. On one side of the second gear 8, there is a rubber roller shaft 9. At both ends of the rubber roller shaft 9, there are fixedly connected transmission shafts 10. One end of the left transmission shaft 10 is fixedly connected to the second gear 8. Behind the transmission shaft 10, there is a limit seat 11. The limit seat 11 includes a limit bracket 1101 and a limit wheel 1102. On the front side of the right bracket 2, there is fixedly connected an adjustment base 12.

[0022] On the front side of the adjustment base 12, there is fixedly connected a limit strip 13. On the surface of the limit strip 13, there is a sliding connection with an adjustment seat 14. Behind the adjustment seat 14, there is a threaded connection with a lead screw 15, ensuring that the adjustment seat 14 can only move horizontally on the adjustment base 12; the limit bracket 1101 is in a "U" shape. At the top and bottom on both sides of the limit bracket 1101, there are rotatably connected limit wheels 1102 to prevent the rubber roller shaft 9 from falling off the limit seat 11. There are two groups of limit seats 11, and the two groups of limit seats 11 are respectively in contact connection with the left transmission shaft 10 and the right transmission shaft 10, playing a supporting role for the rubber roller shaft 9; on both sides of the right limit seat 11, there are limit sleeves 17 fixedly connected to the transmission shaft 10. The lead screw 15 is rotatably connected to the adjustment seat 14. At the end of the lead screw 15, there is fixedly connected an adjustment handle 16 to adjust the position of the rubber roller shaft 9 on the bracket 2.

[0023] Workflow: The electricity required in this utility model is provided by an external power source. The bracket 2 supports the entire device. The fixed plate 3 supports the left side of the rubber roller shaft 9. The support plate 4 supports the first gear 7, the clutch 5, and the motor 6. The sound insulation cotton is placed on the material rack 1. The sound insulation cotton is pulled to the lower side of the rubber roller shaft 9. There is an adhesive sticker on the surface of the rubber roller shaft 9. By rotating the adjustment handle 16, the lead screw 15 drives the adjustment seat 14 to slide on the adjustment base 12. The existence of the limit strip 13 provides a guiding function for the adjustment seat 14, so that the adjustment seat 14 can only slide along the axial direction of the adjustment base 12. The limit sleeve 17 axially limits the transmission shaft 10 to ensure that the rubber roller shaft 9 can move with the movement of the adjustment seat 14. Since the thickness of the first gear 7 is greater than the thickness of the second gear 8, the meshing state of the first gear 7 and the second gear 8 can be maintained, realizing the horizontal sliding of the rubber roller shaft 9 on the bracket 2 to adjust the position of the rubber roller shaft 9 and achieve uniform glue application. Start the motor 6. The output end of the motor 6 drives the clutch 5 to operate. When the clutch 5 is in the combined state, the first gear 7 rotates, driving the second gear 8 to rotate, causing the transmission shaft 10 to rotate, and finally driving the rubber roller shaft 9 to rotate on the limit seat 11. The limit bracket 1101 supports the limit wheel 1102 and at the same time supports the rubber roller shaft 9 to prevent the rubber roller shaft 9 from falling off the limit frame. The limit wheel 1102 can ensure that the rotation of the rubber roller shaft 9 is smoother. When the clutch 5 is in the separated state, the driven glue application action of the rubber roller shaft 9 can be realized.
