[0002] Steering wheel trim pieces are made of multiple parts using different materials and assembled to meet the requirements of shape, color and design. The assembly process between these parts usually adopts hot melt processing. After the hot melt assembly of each part, the steering wheel trim piece has strict requirements for abnormal noise inspection and must not have any abnormal noise. Therefore, in order to solve the problem of abnormal noise in the steering wheel trim piece, anti-noise oil is usually applied to the bottom of the multiple round holes 101 distributed on the finished steering wheel trim piece 1 (as shown in Figure 1).
[0003] The current method of applying anti-noise oil to the round holes 101 distributed on the steering wheel trim 1 is to apply it manually in dots. However, this method is prone to low work efficiency and missed areas, which ultimately leads to noise. Therefore, an improvement is needed. Summary of the Invention

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Example 1
[0026] Please refer to Figures 2-8. One embodiment of this utility model provides an automatic adhesive application device for steering wheel trim pieces, including a workbench 2. For ease of operation, operating handles 17 are provided on both sides of the workbench 2, allowing for easy lifting of the entire device by gripping the handles 17. To improve the stability and anti-slip properties of the device, a fixed base 15 is provided around the bottom of the workbench 2. An anti-slip sleeve 16 is fitted onto the bottom of each fixed base 15, allowing the device to be placed anywhere, while the anti-slip sleeve 16 provides an anti-slip function. A spray station 3 is provided on the workbench 2, and one or more nozzles 4 are provided on the upper surface of the spray station 3. Corresponding one-to-one with the circular holes distributed on the steering wheel trim piece 1, the spray base 3 is hinged with a flip-up cover plate 6. The cover plate 6 is located outside the nozzle 4, and the lower surface of the cover plate 6 is provided with one or more pressure blocks 7, each pressure block 7 corresponding to one nozzle 4. Below the pressure block 7, there is a push pin 8 that presses the steering wheel trim piece 1 onto the corresponding nozzle 4. The spray base 3 is also provided with a liquid pump 10 located at the center of the spray base 3 and a liquid reservoir 9 located on the side of the spray base 3. The input end of the liquid pump 10 is connected to the liquid reservoir 9. In order to improve the liquid supply effect, there are two liquid reservoirs 9, located on the left and right sides of the steering wheel trim piece 1 respectively. Each liquid reservoir 9 has an opening at the top, and a seal is closed at the opening. A cover plate 901 is provided, and an operating handle 35 is fixed on the sealing cover plate 901. By providing the operating handle 35 on the sealing cover plate 901, it is convenient to open the sealing cover plate 901 later to add spray liquid (abnormal noise oil) into the liquid storage tank 9. The output end of the spray pump 10 is connected to the nozzle 4 to deliver the liquid in the liquid storage tank 9 to the nozzle 4. The side of the housing of the spray pump 10 is provided with a positioning notch 10-1. In order to facilitate the fixing of the steering wheel decoration part 1, the top of the housing of the spray pump 10 is provided with a limiting groove 10-2 to facilitate the limiting of the steering wheel decoration part 1, and the positioning notch 10-1 facilitates the insertion of the bracket on the side of the steering wheel decoration part 1. As shown in Figure 1, since the two sides of the steering wheel decoration part 1 are axially symmetrical, Therefore, the structure of the steering wheel trim 1 is consistent on both sides, and the arrangement of the corresponding round holes 101 on both sides is also consistent. Therefore, the distribution of the nozzles 4 above the spray base 3 is also symmetrical about the center line of the spray base 3. In order to avoid liquid spraying, as shown in Figures 6 and 7, a sponge block 401 for absorbing liquid is provided in each nozzle 4, and a portion of the sponge block 401 is exposed above the nozzle 4. During the later dotting process, the sponge block 401 is used to penetrate the liquid and apply the black anti-noise oil to the bottom of each round hole 101. For easy viewing, only one sponge block 401 is provided on one nozzle 4 in Figure 6, and the others are not provided. During the later work, it is necessary to insert sponge blocks 401 into each nozzle 4.
[0027] To ensure smooth liquid flow, the spray base 3 includes an upper cover 301 and a lower cover 302 that overlap each other. A flow channel 303 is provided in the lower cover 302 to connect the various nozzles 4. A spray hole 304 is provided on the upper cover 301 to connect with the corresponding nozzle 4, and the spray hole 304 is connected to the flow channel 303. In this embodiment, there are multiple flow channels 303, and the multiple flow channels 303 are connected to each other and connected to the liquid storage tanks 9 on both sides through the liquid pump 10. How the flow channels 303 are connected and how they are connected to the liquid storage tanks 9 on both sides through the liquid pump 10 are conventional technologies in the art, so they will not be described in detail.
[0028] To facilitate rotation, two positioning seats 11 are spaced apart on the upper cover 301. Rotating shafts 12 are fixed on both sides of the cover plate 6, and the rotating shafts 12 are hinged to the positioning seats 11. For easy installation, a hinge seat 13 is fixed on both rear sides of the cover plate 6, and a rotating shaft 12 is provided on the outer side of each hinge seat 13. During operation, the cover plate 6 can be flipped by holding it in hand, so that the cover plate 6 can be flipped or pressed onto the steering wheel trim piece 1, which is convenient for user operation.
[0029] The specific working principle of this structure is as follows: Based on the distribution and number of the circular holes 101 on the corresponding steering wheel trim piece 1, this device sets the corresponding number of nozzles 4, pressure blocks 7, and ejector pins 8. To facilitate fixing the steering wheel trim piece 1, a limiting groove 10-2 is provided on the top of the injection pump housing to fix the steering wheel trim piece 1. Simultaneously, the bottom of the corresponding circular hole 101 on the steering wheel trim piece 1 is placed on a corresponding nozzle 4. Then, the cover plate 6 is flipped and pressed onto the steering wheel trim piece 1. At this time, the ejector pin 8 is inserted into the circular hole 101, ensuring that the bottom of the circular hole 101 abuts against the nozzle 4's nozzle opening. The injection pump is then driven. In step 10, the liquid in the reservoir 9 flows out from the nozzle 4 and is dotted onto the bottom of the round holes 101. Therefore, with this structure, once the corresponding number of nozzles 4, pressure blocks 7, and ejector pins 8 are set according to the distribution and number of round holes 101 on the corresponding steering wheel trim 1, all round holes 101 on the same steering wheel trim 1 can be dotted, preventing the problem of missing a round hole 101 due to manual operation. Furthermore, the dotting is more uniform, further improving work efficiency. Later, when the liquid in the reservoir 9 is insufficient, liquid only needs to be manually added to the reservoir 9. After dotting is completed, the steering wheel trim 1 can be manually removed. Example 2
[0030] Please refer to Figure 9. This embodiment discloses an automatic adhesive application device for steering wheel trim. For ease of operation, an operating handle 14 is provided above the cover plate 6. By providing an operating handle 14 above the cover plate 6, it is convenient to open the cover plate 6 later, making it easier for the user to operate.
