Abstract
Description
Technical Field
[0001] This utility model relates to the field of bonding device technology, and in particular to a bonding device for automotive interior leather. Background Technology
[0002] An automotive interior leather bonding device is an automated or semi-automatic equipment used to precisely bond leather materials to automotive interior components. It typically includes a feeding mechanism, a positioning system, a heating and pressurizing component, and a conveying device. This device ensures precise alignment between the leather and the interior substrate through structural design, enhances material adhesion through heating, and achieves tight bonding by applying uniform pressure through the pressurizing component. This guarantees the flatness, firmness, and durability of the interior leather and is widely used in automotive interior production lines to meet the standardization and high-quality requirements of automotive interior processing.
[0003] Existing automotive interior leather bonding devices employ a single heating method, often using fixed temperature and pressure parameters. This makes it difficult to adapt to the characteristics of different automotive components (such as curved seat surfaces, door panel edges, and irregularly shaped dashboard structures). This results in problems such as localized overheating that damages the leather, uneven pressure causing bubbles or wrinkles, or insufficient heating leading to weak adhesion. Furthermore, the single bonding method cannot accommodate the different deformation requirements of hard substrates and soft leather, resulting in poor bonding accuracy for complex curved components and a tendency for edges to curl up. This makes it difficult to meet the process requirements of diverse interior parts, affecting product consistency and quality stability. Utility Model Content

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0026] Example 1: Refer to Figure 1 - Figure 5As shown: This embodiment includes an automotive interior leather bonding device, comprising a table body 1, a support rod body 2, and a bonding assembly 3. The table body 1 includes a first movable block 101, which is fixedly installed on the top of the table body 1. The support rod body 2 is movably installed inside the first movable block 101. The support rod body 2 includes two slide rails 201 and two slide rods 202. The two slide rails 201 are fixedly installed on the front surface of the support rod body 2, and the two slide rods 202 are fixedly installed on the outer walls of both sides of the support rod body 2. The two slide rails 201 and the two slide rods 202 can slide externally respectively. A sliding groove 303 and a fixing frame 301 are fitted with a fitting component 3. A fixing plate 302 is fixedly installed on one side of the fixing frame 301. Two sliding grooves 303 are opened on the back of the fixing plate 302. A heat-resistant silicone sleeve 304 is fixedly installed on the front side of the fixing plate 302. Multiple nichrome wires 305 and springs 306 are installed inside the heat-resistant silicone sleeve 304. Each spring 306 is fitted outside each nichrome wire 305. Each nichrome wire 305 and spring 306 penetrates the inner wall of the heat-resistant silicone sleeve 304. Each nichrome wire 305 and spring 306 is fixedly installed at both ends of the fixing plate 302.
[0027] The overall effect of the first embodiment is as follows: the table body 1 provides basic support, the first movable block 101 is used to install the support rod body 2, so that it can move and adjust its position within a certain range, the slide rail 201 on the support rod body 2 cooperates with the slide groove 303 of the bonding component 3, and the slide rod 202 cooperates with the fixed frame 301, so that the bonding component 3 can slide flexibly along the support rod to achieve position adjustment. In the bonding component 3, the fixed frame 301 and the slide rod 202, the slide groove 303 and the slide rail 201 are linked, driving the fixed plate 302 and the heat-resistant silicone sleeve 304 to move. Inside the fixed plate 302, the spring 306 is sleeved on the outside of the nickel-chromium wire 305, and the two pass through the heat-resistant silicone sleeve 304 and are fixed at both ends. When working, the nickel-chromium wire 305 is energized and heats up, and the heat passes through the heat-resistant silicone sleeve 304. The sleeve 304 transfers heat to the leather, while the spring 306, utilizing its own elasticity and curvature changes, provides a pressing force for the leather to adhere, resulting in a tighter fit. The advantages are threefold: First, through the sliding cooperation of the slide rail 201, slide rod 202, slide groove 303, and fixing frame 301, the bonding component 3 can be flexibly adjusted to adapt to interior panels of different sizes and curvatures, offering strong versatility. Second, the combination of heating with the nickel-chromium wire 305 and pressing with the spring 306 allows for simultaneous heating and pressing during bonding, improving bonding efficiency and quality and reducing issues such as air bubbles and poor adhesion. Third, the heat-resistant silicone sleeve 304 encases the nickel-chromium wire 305 and spring 306, protecting both while ensuring even heat transfer and preventing scratches on the leather, thus guaranteeing the device's durability and the leather bonding effect.
[0028] Example 2: According to Figure 1 - Figure 7As shown: A support platform 203 is fixedly installed on the outer wall of the support rod body 2. A lifting assembly 4 is fixedly installed on the top of the support platform 203. The lifting assembly 4 includes a motor 401. A lead screw 402 is fixedly connected to the shaft end of the motor 401. A nut 403 is movably sleeved on the outer wall of the lead screw 402. One side of the nut 403 is fixedly installed on the outer wall of the fixed frame 301. A second movable block 102 is fixedly installed on the top of the table body 1. An tilting assembly 5 is movably connected inside the second movable block 102. The tilting assembly 5 includes a cylinder 501. A U-shaped frame 502 is fixedly installed at the shaft end of the cylinder 501. Both inner walls of the U-shaped frame 502 are movably installed at the center of the support rod body 2.
[0029] The overall effect of the second embodiment is as follows: The table body 1 serves as the base support, with the second movable block 102 at its top for mounting the tilting component 5. The first movable block 101 mounts the support rod body 2. The support platform 203 on the outer wall of the support rod body 2 fixes the lifting component 4. In the lifting component 4, the motor 401 drives the lead screw 402 to rotate, which in turn moves the nut 403. Because the nut 403 is connected to the fixing frame 301 of the bonding component 3, the bonding component 3 can be raised and lowered along the support rod body 2 to adjust the bonding height. The cylinder 501 of the tilting component 5 extends and retracts, driving the support rod body 2 to rotate around the second movable block 102 via the U-shaped frame 502 at the shaft end, adjusting the tilt angle of the support rod body 2 and the bonding component 3. The bonding component 3 relies on the fixing frame 301 and... The sliding rod 202 and sliding groove 303 of the support rod body 2 cooperate to achieve position sliding adjustment. The internal nickel-chromium wire 305 is energized and heated, and the spring 306 provides pressing force in accordance with the curvature. Heat and pressure are transferred through the heat-resistant silicone sleeve 304. The advantages are that the lifting component 4 allows the bonding component 3 to be precisely adjusted in height to adapt to different bonding needs, and the tilting component 5 allows the device to flexibly adjust the angle according to the inclination of the interior panel to deal with complex curved surfaces. The spring 306 and nickel-chromium wire 305 work together to heat and press simultaneously, improving bonding quality and efficiency and reducing problems such as air bubbles. The heat-resistant silicone sleeve 304 protects the internal structure and evenly transmits force and heat, ensuring the durability of the device and the leather bonding effect. The cooperation of each component makes the device highly versatile and has a good bonding effect, efficiently completing the interior leather bonding operation.
[0030] Working principle: When the equipment is working, the table body 1 serves as the basic support. The support rod body 2 is installed on the first movable block 101, making its position adjustable. The support rod body 2 uses the slide rail 201 and slide rod 202 to cooperate with the slide groove 303 and fixed frame 301 of the bonding component 3, allowing the bonding component 3 to slide flexibly along the support rod to adjust its position. At the same time, the lifting component 4 fixed to the support platform 203 on the outer wall of the support rod body 2 is driven by the motor 401 to rotate the lead screw 402, which drives the nut 403 connected to the fixed frame 301 of the bonding component 3 to move, realizing the height adjustment of the bonding component 3. The tilting component 5 installed on the second movable block 102 at the top of the table body 1 is driven by the extension and retraction of the cylinder 501 and the U-shaped frame 502 to rotate the support rod body 2 around the second movable block 102, adjusting the overall tilt angle. Inside the bonding component 3, the fixed plate 302 The spring 306 is sleeved around the nickel-chromium wire 305 and fixed by passing through the heat-resistant silicone sleeve 304. During operation, the nickel-chromium wire 305 is energized and heats up, which is transmitted to the leather through the heat-resistant silicone sleeve 304. The spring 306, in conjunction with the curvature, provides pressing force, which has significant advantages. The sliding cooperation of the slide rail 201, slide rod 202, slide groove 303, and fixing frame 301 makes the position of the bonding component 3 flexibly adjustable, adaptable to interior panels of different sizes and curvatures, with strong versatility. The lifting and tilting component 5 allows the device to be adjusted in height and angle as needed to deal with complex curved surfaces. The spring 306 and the nickel-chromium wire 305 work together to heat and press simultaneously, improving bonding quality and efficiency, and reducing problems such as air bubbles. The heat-resistant silicone sleeve 304 protects the internal structure, transmits force and heat evenly, prevents scratches on the leather, and ensures the durability of the device and the bonding effect. All components work together to achieve efficient and high-quality interior leather bonding operations.
[0031] By following the steps outlined above, you can complete the use of the car interior leather bonding device.
