Description

Technical Field

[0001] This utility model belongs to the technical field of automotive headlight fixtures, specifically relating to a special fixture for UV spraying of through-type headlights. Background Technology

[0002] Surface coating is a crucial step in automotive lighting manufacturing. A high-quality coating not only enhances the aesthetics of the lights but also improves their weather resistance, corrosion resistance, and abrasion resistance, extending their lifespan. UV coating technology, as an advanced surface treatment process, has been widely adopted in automotive lighting manufacturing due to its unique advantages.

[0003] UV spraying is a process that uses ultraviolet (UV) light to instantly cure coatings into a film. Compared with traditional thermosetting coating processes, UV spraying has the significant advantages of fast curing speed and high production efficiency. Under the action of UV light, coatings can cure rapidly within seconds to tens of seconds, greatly shortening the production cycle, improving production efficiency, and meeting the needs of large-scale, high-efficiency production in the automotive industry.

[0004] Furthermore, UV coating offers superior coating performance. The cured coating exhibits high hardness, high gloss, and excellent adhesion, effectively resisting environmental erosion and maintaining the aesthetic appeal and stable performance of the lamp surface. Simultaneously, the coatings used in UV coating processes have low volatile organic compound (VOC) content, resulting in minimal environmental pollution and meeting the environmentally friendly production requirements of the modern automotive manufacturing industry.

[0005] Full-width headlights typically have complex shapes and curved surfaces. Existing general-purpose spraying fixtures struggle to ensure consistent distance and angle between the headlight surface and the spray gun when fixing the headlight. This results in uneven paint application during UV spraying, with some areas having excessively thick coatings that are prone to defects such as runs and orange peel, while other areas have insufficient coatings, failing to achieve the desired protective and decorative effects, thus impacting the overall quality and aesthetic consistency of the headlight.

[0006] Because the size, shape, and structure of the continuous headlights vary significantly across different car models, existing painting fixtures are often designed and used only for specific headlight models, lacking versatility. When automakers launch new models or improve the headlights of existing models, they need to redesign and manufacture the corresponding painting fixtures. This not only increases production costs but also extends the production preparation cycle, affecting the company's market responsiveness and competitiveness. Utility Model Content

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0025] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the special fixture for UV spraying of through headlights includes a connecting seat 1 for connecting to the spraying turntable. A fixing frame 2 is provided at the top of the connecting seat 1. A set of opposing first support frames 3 are movably installed on the fixing frame 2. A second support frame 4 is movably installed between the two first support frames 3. The tops of all the first support frames 3 and the second support frames 4 form an arc shape and contact the arc-shaped bottom of the through headlight.

[0026] This utility model proposes a special fixture for UV spraying of through-type headlights. The connecting seat 1 is the connecting component between the entire fixture and the spraying turntable. Its function is to fix the fixture on the spraying turntable and provide basic support for the subsequent operation of the fixture and spraying operations. It is located at the bottom of the fixture. The fixing bracket 2 is set at the top of the connecting seat 1 and serves to support and install other components. It is the middle support part in the fixture structure.

[0027] There is one set (two) of first support brackets 3, which are movably mounted on the fixed bracket 2. The first support brackets 3 can be moved or adjusted to a certain extent on the fixed bracket 2 to accommodate different specifications or installation requirements of the continuous headlights. The second support bracket 4 is movably mounted between the two first support brackets 3, and is also movable, cooperating with the first support brackets 3.

[0028] The tops of all the first support brackets 3 and the second support brackets 4 together form an arc-shaped structure. This arc-shaped structure contacts the arc-shaped bottom of the through-type headlight to stably support the through-type headlight and ensure that the headlight position is fixed during the painting process and will not shake or shift.

[0029] During UV coating of the continuous headlight, the special fixture is first connected to the coating turntable via the connecting seat 1, allowing the fixture to rotate with the turntable. Then, according to the specific specifications and dimensions of the continuous headlight, the positions of the first support bracket 3, which is movably mounted on the fixed frame 2, and the second support bracket 4, installed between the two first support brackets 3, are adjusted so that the arc-shaped structure formed by the tops of the first support brackets 3 and the second support bracket 4 perfectly fits the arc-shaped bottom of the continuous headlight. The continuous headlight is placed on the support surface formed by the arc-shaped structures at the top of the first support brackets 3 and the second support bracket 4. Because the arc-shaped structure matches the shape of the headlight's bottom, it provides stable and reliable support. During the coating process, the coating turntable rotates the fixture and the continuous headlight placed on the fixture, allowing the UV coating to be evenly sprayed onto the headlight surface, ensuring coating quality and effect.

[0030] Combination Figure 1 , Figure 2 and Figure 3 As shown, the first support frame 3 includes a first bracket 31 mounted on the fixed frame 2, and a first support frame 32 is connected to the first bracket 31.

[0031] Specifically, the first bracket 31 is the basic mounting component of the first support frame 3, and is mounted on the fixed frame 2. The first bracket 31 is responsible for fixing the first support frame 3 to the fixed frame 2 as a whole, and serves as a connecting bridge between the first support frame 3 and the fixed frame 2. The first support frame 32 is connected to the first bracket 31 and is the part of the first support frame 3 that directly provides support.

[0032] First, accurately install the first bracket 31 into the preset position on the fixed frame 2, ensuring a firm connection between the first bracket 31 and the fixed frame 2, providing a stable foundation for subsequent support work. This step requires ensuring the installation accuracy of the first bracket 31, as any deviation in its position may affect the overall support effect of the first support frame 3 on the continuous headlight.

[0033] After the first bracket 31 is installed, the first support frame 32 is connected to the first bracket 31. According to the shape and size of the through headlight, the first support frame 32 is adjusted to a suitable position and angle so that the support surface at its top can fit against a specific part of the headlight, providing uniform and stable support for the headlight.

[0034] During the spraying process, the fixture rotates with the spraying turntable, and the first support frame 3 rotates accordingly. At the same time, the first support frame 32 always maintains stable support for the headlight, ensuring that the UV coating can be evenly sprayed on the surface of the headlight and avoiding problems such as uneven spraying and defects caused by headlight shaking or displacement.

[0035] Combination Figure 2 , Figure 3 and Figure 4 As shown, the first bracket 31 has a plurality of first bolt holes 311, and the first support frame 32 has a first groove 321 that matches the first bolt holes 311.

[0036] Specifically, a plurality of first bolt holes 311 are provided on the first bracket 31. These first bolt holes 311 are evenly distributed or distributed on the first bracket 31 according to a specific pattern, and their number is determined according to actual design requirements, providing fixing points for subsequent connection with the first support frame 32. The diameter of the first bolt holes 311 matches the specification of the bolts used to ensure the stability of the connection.

[0037] The first support frame 32 has a first groove 321 that matches the first bolt hole 311. The first groove 321 is elongated, and its length and width are designed to meet the position adjustment requirements of the first support frame 32 relative to the first bracket 31. The width of the first groove 321 is slightly larger than the diameter of the bolt, so that the bolt can slide smoothly in the groove, while ensuring that there is sufficient friction between the first support frame 32 and the first bracket 31 to fix their relative positions when the bolt is tightened.

[0038] Combination Figure 2 , Figure 3 and Figure 4 As shown, the second support frame 4 includes a second bracket 41 disposed on the fixed frame 2, and a second support frame 42 is slidably sleeved on the second bracket 41.

[0039] Specifically, the second bracket 41 is set on the fixed frame 2, which acts as a bridge connecting the fixed frame 2 and the second support frame 42, providing basic support and fixing points for the entire second support frame 4, and ensuring that the second support frame 4 can be stably positioned in the corresponding position of the fixture.

[0040] The second support frame 42 is slidably fitted onto the second bracket 41. The second support frame 42 has internal holes or channels that match the shape of the second bracket 41, allowing it to slide along the axial direction or a specific direction of the second bracket 41. The second support frame 42 is the part that directly contacts the supported object (such as a continuous headlight). Its surface shape and structural design are optimized according to the bottom shape of the headlight to provide uniform and stable support, preventing the headlight from shaking or shifting during the painting process.

[0041] First, accurately install the second bracket 41 into the preset position on the fixed frame 2, ensuring a firm connection between the second bracket 41 and the fixed frame 2, providing a stable foundation for the subsequent sliding and supporting operation of the second support frame 42. At this time, the second support frame 42 is in its initial position, which may be located at one end or in the middle of the second bracket 41, depending on the initial design of the fixture.

[0042] Depending on the actual size and shape of the continuous headlight, the position of the second support bracket 42 needs to be adjusted. Since the second support bracket 42 is slidably fitted onto the second bracket 41, the operator can manually push the second support bracket 42 to slide it along the axis or a specific direction of the second bracket 41. During the sliding process, the second support bracket 42 can move freely within a certain range until it reaches a position that can contact the bottom of the headlight and provide stable support. This allows the second support bracket 4 to adapt to continuous headlights of different specifications and shapes, improving the versatility and flexibility of the fixture.

[0043] Once the second support frame 42 is adjusted to the appropriate position, it needs to be fixed to prevent displacement during the spraying process due to jig rotation or external forces. The second support frame 42 can stably support the through-type headlight and work together with other supporting components in the jig to ensure that the headlight remains stationary during the spraying process, ensuring that the UV coating can be evenly sprayed onto the headlight surface, improving the spraying quality and effect.

[0044] Combination Figure 2 , Figure 3 and Figure 5 As shown, the second support frame 42 is provided with a second sliding groove 421 that matches both sides of the second bracket 41, the second bracket 41 is provided with a second bolt hole 411, and the second sliding groove 421 is provided with a third sliding groove 4211 that matches the second bolt hole 411.

[0045] Specifically, a second bolt hole 411 is provided on the second bracket 41. The diameter of the second bolt hole 411 is determined according to the specification of the selected bolt, and its position distribution usually takes into account the adjustment range and fixing requirements of the second support frame 42. It may be evenly distributed in a specific area of ​​the second bracket 41 so that the second support frame 42 can be fixed in different positions.

[0046] The second support frame 42 is provided with second sliding grooves 421 that match the two sides of the second bracket 41. The shape and size of the second sliding grooves 421 are adapted to the outer shape of the two sides of the second bracket 41, so that the second bracket 41 can be embedded in the second sliding grooves 421, and the second support frame 42 can slide along the second bracket 41. This provides a basis for adjusting the position of the second support frame 42 relative to the second bracket 41.

[0047] A third groove 4211 matching the second bolt hole 411 is also provided on the second groove 421. The third groove 4211 is elongated, and its length direction is consistent with the sliding direction of the second support frame 42. Its width is slightly larger than the diameter of the bolt. In this way, when the second support frame 42 slides, the bolt can move smoothly in the third groove 4211, while ensuring that there is sufficient friction between the second support frame 42 and the second bracket 41 to fix their relative positions when the bolt is tightened.

[0048] Combination Figure 2 , Figure 3 and Figure 5 As shown, the fixing frame 2 has multiple sets of evenly arranged positioning holes 21, and the first bracket 31 and the second bracket 41 are fixedly installed on the positioning holes 21 by bolts.

[0049] Specifically, multiple sets of evenly arranged positioning holes 21 are provided on the mounting bracket 2. These positioning holes 21 are generally circular in shape, and their diameter is designed according to the specifications of the bolts used to ensure that the bolts can pass through smoothly and achieve a firm connection. The multiple sets of positioning holes 21 are evenly distributed in a specific area of ​​the mounting bracket 2. This area is determined according to the installation requirements of the first bracket 31 and the second bracket 41 and the overall layout of the fixture, providing multiple selectable installation positions for the first bracket 31 and the second bracket 41 to accommodate the support requirements of through-type headlights of different specifications and shapes.

[0050] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the top of both the first support frame 32 and the second support frame 42 are provided with toothed anti-slip texture 5.

[0051] Specifically, the toothed anti-slip texture 5 is evenly distributed on the top surfaces of the first support frame 32 and the second support frame 42. The top surfaces are the parts that directly contact the continuous headlight; the toothed anti-slip texture 5 increases the friction between them. The toothed anti-slip texture 5 exhibits a regular toothed structure, with each tooth potentially being triangular, trapezoidal, or rectangular. The height, width, and spacing of the teeth are designed according to actual needs. Generally, the height and width of the teeth are moderate, and the spacing is reasonable, to ensure sufficient friction without damaging the bottom surface of the headlight.

[0052] Combination Figure 1 , Figure 2 and Figure 3 As shown, the connecting seat 1, the fixing frame 2, the first support frame 3 and the second support frame 4 are all made of metal.

[0053] Specifically, the connector 1 is made of metal, which gives it sufficient strength and rigidity to withstand the weight of the fixture itself and the vibration and external forces generated by the operation of the equipment during the spraying process. This ensures the stability and reliability of the connection and prevents loosening or deformation, which would affect the overall precision of the fixture and the spraying quality.

[0054] The metal material gives the mounting bracket 2 high strength and good stability, enabling it to withstand the weight of the various components on the fixture as well as the weight of the continuous headlight, while resisting collisions and impacts that may occur during the painting process. Furthermore, the metal mounting bracket 2 can be further enhanced in rigidity and deformation resistance through reasonable structural design, such as adding reinforcing ribs, ensuring that the fixture maintains a stable structural shape during long-term use.

[0055] The first metal support bracket 3 has sufficient strength to support the weight of the headlight and maintains its shape stability during the painting process, preventing deformation due to the weight of the headlight or the spraying force. Furthermore, the metal material can be treated with surface treatments (such as chrome plating and painting) to improve its corrosion resistance, preventing erosion by chemicals during painting and extending its service life.

[0056] The use of metal ensures the strength and stability of the second support bracket 4, enabling it to reliably support the other part of the headlight. In the adjustable structure, the metal components can withstand the forces and wear during adjustment, ensuring the normal operation and long-term stability of the adjustment function. At the same time, the corrosion resistance of the metal material also helps to guarantee the service life of the second support bracket 4 in harsh painting environments.

[0057] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
