[0002] With the wave of the development of new energy vehicles sweeping across the globe, the market penetration rate of new energy vehicles is increasing year by year. After the engine of traditional fuel vehicles is replaced, the tire noise of new energy vehicles contributes more significantly to the overall vehicle noise compared to traditional fuel vehicles, becoming the main factor of the overall vehicle noise of new energy vehicle models. With the continuous iteration and upgrading of automobile consumption, the market's demand for the safety and comfort of tires is also getting higher and higher. The rapid popularization of new energy vehicles has attracted wide attention to silent tires with obvious silent effects. In the production process of silent tires, sponge laminating is an important process. In the traditional production process of silent tires, operators need to complete the lamination and pressing of sponges, which is not conducive to ensuring the lamination accuracy and uniformity. The manual participation rate is high throughout the process, the labor intensity of operators is large, and the production efficiency is low, which in turn affects the dynamic balance and uniformity of the tires and the process quality control during the lamination process.

Preferably, the lifting driving device 10 adopts a cylinder, the cylinder is connected to the lifting frame 2 through the floating joint 11, and the floating joint 11 can adapt to minute errors, ensuring the stability and reliability of the connection and prolonging the service life of the cylinder.

[0033] As an implementation manner, the lifting frame 2 is installed on the main frame 1 through a linear guide rail 20. The linear guide rail 20 is arranged along the vertical direction. The lifting driving device 10 drives the lifting frame 2 to lift along the linear guide rail 20. A buffer is arranged between the lifting frame 2 and the main frame 1, making the movement of the lifting frame 2 smooth, playing a role in shock absorption and impact mitigation.

[0034] As an implementation manner, the sponge film laminating and collecting device 7 is arranged outside the inlet of the sponge guiding groove 5. After the film of the sponge is torn off and clamped by the sponge film laminating and collecting device 7, it is convenient to put the sponge into the sponge guiding groove 5.

[0035] As an implementation manner, the tire placement part 3 includes two rotating rollers arranged in parallel. A driving motor 30 is arranged on one side of the rotating rollers. The two rotating rollers are respectively a driving roller 31 and a driven roller 32. A driving sprocket 33 is arranged on the output shaft of the driving motor 30. A driven sprocket 34 is arranged on one side of the driving roller 31. A chain 35 is connected between the driving sprocket 33 and the driven sprocket 34. The driving roller 31 is connected to the driven roller 32 through a transmission belt. The driving motor 30 drives the driving roller 31 to rotate through the chain 35. Subsequently, the driving roller 31 drives the driven roller 32 to rotate under the action of the transmission belt, so that the tire 8 rotates accordingly under the action of the driving roller 31 and the driven roller 32.

[0036] Preferably, the driving motor 30 adopts a reduction motor, which is beneficial to realizing the sponge fitting of the tire 8 and has the advantages of stable operation, low noise and small vibration.

[0037] As an implementation manner, both the driving roller 31 and the driven roller 32 are installed on the main frame 1 through pedestal bearings.

The tire 8 rotates accordingly under the action of the driving roller 31 and the driven roller 32, and the linear driving device plays a role in clamping and centering the tire 8. In some other implementation manners, any one of the clamping members 40 is fixedly installed on the main frame 1, and the other clamping member 40 is installed on the main frame 1 through a linear driving device. The linear driving device adopts a hand-cranked guide rail slide 41. When it is necessary to clamp and center, this clamping member 40 moves towards the other clamping member 40 under the action of the hand-cranked guide rail slide 41, approaches and contacts the outer side of the tire 8. Under the action of the clamping member 40, the rotating tire 8 realizes the clamping and centering of the tire 8.

[0041] As an implementation manner, the upper part of the clamping member 40 is set as a conical part, and the tip of the conical part is set as an arc.

[0042] The working principle of this embodiment:

[0043] The reduction motor drives the driving roller 31 and the driven roller 32 to rotate. The worker places the tire 8 that needs to be pasted with sponge on the driving roller 31 and the driven roller 32 to roll, and performs centering for one circle through the clamping and centering device. Subsequently, the lifting frame 2 descends under the drive of the air cylinder, tears the film of the sponge, the sponge film collecting device 7 clamps the film, the sponge is put into the sponge guiding groove 5 and extends out of the outlet of the sponge guiding groove 5. The sponge rotates with the tire 8 and is pressed against the inner wall of the tire 8 under the action of the pressing roller 60 of the sponge pressing device 6 to complete the preliminary fitting of the sponge. Subsequently, the lifting frame 2 continues to descend under the action of the air cylinder, so that the pressure of the sponge pressing device 6 on the sponge increases, and the sponge in the tire 8 is rolled at least one more week, so that the sponge is more firmly attached;

[0044] It can be understood that the descending height of the lifting frame 2 is a parameter preset according to the thickness of the tire 8. An articulated electric operation box 12, an electric cabinet, and an air cabinet are arranged on the side of the main frame 1, and the electrical control system of the articulated electric operation box 12 effectively controls the sponge fitting process.
