[0046] With energy shortages and environmental pollution becoming increasingly serious, energy conservation and emission reduction have become crucial missions for the automotive industry. Lightweighting of automobiles is significant for improving vehicle performance, reducing operating costs, and protecting the environment. Plastic tailgates are a typical application of lightweight automotive materials. An increasing number of car models are adopting plastic tailgates.

[0047] Plastic tailgates typically consist of an inner panel and an outer panel. The outer panel is usually injection molded from modified polypropylene. However, the heat distortion temperature of modified polypropylene is around 100°C, making it impossible to install it on the vehicle body for simultaneous painting (the vehicle body is made of steel, and the paint drying temperature is 150°C for 30 minutes). Therefore, the plastic tailgate outer panel needs to be painted separately (using low-temperature paint and baking at 80-90°C for 30 minutes, the same baking temperature as plastic parts such as bumpers).

[0048] In related technologies, when painting plastic tailgates, the tailgate is typically hung vertically on a fixture for painting. Using this fixture for painting...

[0049] In view of this, embodiments of this application provide a spray painting fixture, which aims to solve the above-mentioned problems.

[0050] Please see Figure 1 A painting fixture according to an embodiment of this application includes a positioning component 100 and a support component 200. The positioning component 100 extends along a first direction X, and the support component 200 is disposed on one side of the positioning component 100 and connected to the positioning component 100. The support component 200 extends along a second direction Y. The positioning component 100 and the support component 200 are used to cooperate in supporting the plastic tailgate during the painting process; wherein the first direction X intersects the second direction Y.

[0051] In this embodiment, the positioning component 100 is used to position the plastic tailgate, and the support component 200 is used to support the plastic tailgate. By setting the positioning component 100 and the support component 200 to intersect, it is possible to achieve both large-scale positioning of the plastic tailgate along the first direction X and large-scale support along the second direction Y, thereby achieving multi-point support for the plastic tailgate, reducing local stress, and thus effectively reducing the possibility of deformation of the plastic tailgate in high-temperature environments and improving the yield rate of the plastic tailgate.

[0052] Specifically, in this embodiment, the positioning component 100 extends along the first direction X, and its positioning points are spaced apart along the first direction X, thus enabling multi-point positioning of the plastic tailgate along the first direction X. The support component 200 extends along the second direction Y, providing multi-point support for the plastic tailgate along the second direction Y. Since the first direction X intersects with the second direction Y, the support component 200 and the positioning component 100 also intersect, forming a larger support and positioning plane. The more support points there are, the smaller the corresponding local stress, thereby effectively reducing the problem of local deformation of the plastic tailgate during painting.

[0053] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the positioning component 100 includes a crossbar 110 and a plurality of positioning elements 120. The crossbar 110 extends along a first direction X and is connected to the support component 200. The plurality of positioning elements 120 are disposed on one side of the crossbar 110 and are all connected to the crossbar 110. The plurality of positioning elements 120 are spaced apart along the first direction X, and at least two positioning elements 120 are disposed opposite to each other on both sides of the support component 200 along the first direction X and spaced apart from the support component 200.

[0054] In this embodiment, the crossbar 110 extends along the first direction X to provide fixing points for multiple positioning members 120. The multiple positioning members 120 are used to connect with the positioning points corresponding to the plastic tailgate, thereby realizing multi-point positioning of the plastic tailgate, thereby improving the positioning stability of the plastic tailgate, reducing the possibility of movement of the plastic tailgate, and thus benefiting the uniformity of the paint spraying.

[0055] Specifically, in this embodiment, the plastic tailgate typically has at least two mounting holes spaced apart along the first direction X. The positioning member 120 can be a positioning pin, which can then pass through the mounting holes on the plastic tailgate. Since there are at least two positioning points, stable positioning can be achieved to prevent torsion. Furthermore, a support component 200 along the second direction Y provides support points for the plastic tailgate. The positioning component 100 and the support component 200 cooperate to form a polygonal support structure, making the plastic tailgate approximately flat on the painting fixture. This effectively reduces localized stress and thus minimizes the possibility of localized deformation.

[0056] In addition, the painting fixture of this application has a simple structure. The crossbar 110, the positioning part 120 and the support component 200 can all be directly welded into shape using the corresponding profiles. Therefore, it is only necessary to weld and assemble the fixture using profiles of the corresponding size, resulting in low manufacturing cost.

[0057] like Figure 2 As shown, in some embodiments, the support assembly 200 includes a first support portion 210, a second support portion 220, and a third support portion 230. The first support portion 210 is connected to the crossbar 110. The two ends of the first support portion 210 are disposed opposite to each other on both sides of the crossbar 110 along the second direction Y, and extend along the second direction Y in a direction away from the crossbar 110. The second support portion 220 is connected to one end of the first support portion 210, extends along the first direction X, and is spaced apart from the crossbar 110. The third support portion 230 is connected to the end of the first support portion 210 away from the second support portion 220, extends along the first direction X, and is spaced apart from the crossbar 110.

[0058] In this embodiment, by setting a first support portion 210 extending along the second direction Y, and setting a second support portion 220 and a third support portion 230 at both ends of the first support portion 210 along the second direction Y, the plastic tailgate can be supported by the second support portion 220 and the third support portion 230, ensuring that the plastic tailgate has multiple force-bearing parts, which cooperate with multiple positioning parts 120 and crossbar 110. Through multi-point support and positioning, the local force on the plastic tailgate is reduced, thereby reducing deformation and improving the paint qualification rate of the plastic tailgate.

[0059] It should be noted that in this embodiment, both the second support portion 220 and the third support portion 230 extend along the first direction X. This can further increase the support area of ​​the second support portion 220 and the third support portion 230, thereby improving the further dispersion of force and further reducing the possibility of deformation of the plastic tailgate.

[0060] It should also be noted that the painting fixture of this application is positioned along the first direction X by multiple positioning parts 120, and supported along the second direction Y by the second support part 220 and the third support part 230. At the same time, the second support part 220 and the third support part 230 both extend along the first direction X, thus ensuring that the second support part 220 and the third support part 230 have a large support area. Therefore, the positioning component 100 and the support component 200 cooperate with each other to achieve a large range of support and fixation, meet the support and fixation requirements of the plastic tailgate, and prevent the tailgate from falling off due to unstable fixation, thereby improving the safety of painting.

[0061] It should also be noted that in this embodiment, the second support part 220 and the third support part 230 are configured to cooperate with each other. Specifically, they are configured with corresponding long drag surfaces extending along the first direction X according to the shape of the edge of the plastic tailgate, so as to avoid the problem of deformation of the plastic tailgate caused by dragging the tailgate at a single point.

[0062] Please refer to the following: Figure 2 and Figure 3 In some embodiments, multiple positioning elements 120 are connected to one side of the crossbar 110 along the third direction Z; along the third direction Z, the second support 220 and the third support 230 are both disposed on the side of the crossbar 110 where the positioning elements 120 are located, and are spaced apart from the crossbar 110; wherein the third direction Z intersects with the first direction X and the second direction Y respectively.

[0063] In this embodiment, both the second support portion 220 and the third support portion 230 are spaced apart from the crossbar 110 along the third direction Z. This allows the plastic tailgate to be supported solely by the second and third support portions 220 and 230, improving the uniformity of heating during the paint drying process. Simultaneously, supporting the tailgate at a certain height along the third direction Z avoids structural interference during movement and transfer.

[0064] It should be noted that, in this embodiment of the application, the position of the positioning hole on the plastic tailgate corresponding to the positioning part 120 of the painting fixture is the glass covering position during subsequent vehicle assembly, which can avoid appearance defects caused by deformation of the plastic tailgate hanging point or uneven painting of the hanging point hole wall.

[0065] Please refer to the following: Figure 2 and Figure 4In some embodiments, the first support portion 210 includes a first rod 211 and a second rod 212. One end of the first rod 211 is connected to the crossbar 110, and the end of the first rod 211 away from the crossbar 110 is connected to the second support portion 220. The second rod 212 is disposed along the second direction Y on the side of the crossbar 110 away from the first rod 211. One end of the second rod 212 is connected to the crossbar 110, and the end of the second rod 212 away from the crossbar 110 is connected to the third support portion 230.

[0066] In this embodiment of the application, by providing a first rod 211 and a second rod 212 on both sides of the crossbar 110, not only can the second support part 220 and the third support part 230 be supported, but the second support part 220 and the third support part 230 can also be spaced apart from the crossbar 110. In this way, the second support part 220 and the third support part 230 can be used to support the edge of the plastic tailgate as much as possible, thereby improving the uniformity of force distribution.

[0067] It should be noted that in this embodiment of the application, the first rod 211 and the second rod 212 extend upward at an angle, which can both expand the support range and support the plastic tailgate to a certain height to ensure the safety of painting.

[0068] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the first rod 211 and the second rod 212 are both curved, and the concave surfaces of the first rod 211 and the second rod 212 are oriented toward the third rod 213.

[0069] In this embodiment of the application, both the first rod 211 and the second rod 212 are curved, and the bending direction is towards the direction close to the crossbar 110. This structure can not only ensure support, but also increase the distance between the first rod 211 and the second rod 212 and the plastic tailgate, reducing the possibility of the first rod 211 and the second rod 212 interfering with the painting of the plastic tailgate.

[0070] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the first support portion 210 further includes a third rod 213, which extends along the second direction Y and is disposed on the side of the crossbar 110 where the positioning member 120 is provided. The third rod 213 is spaced apart from the crossbar 110 along the third direction Z and is connected to the first rod 211 and the second rod 212 respectively.

[0071] In this embodiment, the third rod 213 is connected to the first rod 211 and the second rod 212 respectively, forming an approximate triangular structure. This can effectively improve the structural stability of the entire first support part 210, thereby improving the support capacity of the first support part 210 for the second support part 220 and the third support part 230.

[0072] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the support component 200 includes a plurality of first support portions 210, which are spaced apart along a first direction X, and each first support portion 210 is connected to a second support portion 220 and a third support portion 230 respectively.

[0073] In this embodiment of the application, by setting multiple first support parts 210, the second support part 220 and the third support part 230 are simultaneously connected to multiple first support parts 210, thereby further improving the stability and support capacity of the overall structure of the support component 200.

[0074] Please refer to the following: Figure 1 , Figure 2 and Figure 3 In some embodiments, a fixing component 300 is also included, which is connected to the positioning component 100, and at least a portion of the fixing component 300 protrudes from the side of the positioning component 100 away from the support component 200.

[0075] In this embodiment of the application, by setting the fixing component 300, the entire painting fixture can be connected and fixed to the corresponding painting conveyor track on the production line, thereby enabling the painting fixture with the plastic tailgate to move and flow on the painting station, and then gradually complete the painting and drying steps.

[0076] It should be noted that at least a portion of the fixing component 300 protrudes from the side of the positioning component 100 away from the support component 200. By connecting this protruding portion to the conveyor rail on the production line, both the positioning component 100 and the support component 200 can be kept away from the conveyor rail, ensuring that the plastic tailgate can be supported above the conveyor rail and avoiding unnecessary interference and wear.

[0077] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 5In some embodiments, the fixing component 300 includes a fixing base 310, a first positioning rod 320, and a second positioning rod 330. The fixing base 310 is connected to the positioning component 100, and its two ends along the second direction Y are disposed opposite to each other on both sides of the positioning component 100. The first positioning rod 320 is disposed along the second direction Y on one side of the positioning component 100 and is connected to the fixing base 310. The end of the first positioning rod 320 away from the fixing base 310 protrudes from the side of the positioning component 100 away from the support component 200. The second positioning rod 330 is disposed along the second direction Y on the side of the positioning component 100 away from the first positioning rod 320 and is connected to the fixing base 310. The end of the second positioning rod 330 away from the fixing base 310 protrudes from the side of the positioning component 100 away from the support component 200.

[0078] In this embodiment, the fixing base 310 is used to connect and fix the first positioning rod 320 and the second positioning rod 330, so that the first positioning rod 320 and the second positioning rod 330 are fixed in a predetermined position. This ensures that when the first positioning rod 320 or the second positioning rod 330 is connected to the conveying rail, the positioning component 100 and the support component 200 can be smoothly supported. On the one hand, this ensures a fixed connection between the painting fixture and the conveying rail; on the other hand, it ensures that the support component 200 and the conveying rail have a suitable height gap, which is beneficial to the smooth painting of the plastic tailgate and improves the paint quality rate of the plastic tailgate.

[0079] It should be noted that the first positioning rod 320 and the second positioning rod 330 are symmetrically arranged at both ends of the fixed base 310. This symmetrical arrangement can be either axially symmetrical (not shown in the attached diagram) or centrally symmetrical, as specifically shown in figures 1 and 2. Figure 5 As shown, the second support part 220 and the third support part 230 can have the same structure and be symmetrically arranged with respect to the crossbar 110. The first bar 211 and the second bar 212 can also have the same structure and be symmetrically arranged with respect to the crossbar 110. In this way, the painting fixture has a symmetrical structure as a whole. When in use, the plastic tailgate can be positioned, assembled and supported without considering the direction, which is beneficial to improving the painting efficiency.

[0080] It should also be noted that in this embodiment, only one positioning rod is used to connect with the conveyor rail to fix the painting fixture. This reduces the difficulty of matching the painting fixture with the conveyor rail, thereby further improving the painting efficiency.

[0081] like Figure 1 As shown in the embodiments of this application, one possible implementation is as follows:

[0082] The fixing component 300 can be welded from 40mm square steel; the supporting component 200 can be welded from φ10mm steel bars, wherein the length of the second supporting part 220 and the third supporting part 230 along the first direction X can be 700mm; the crossbar 110 of the positioning component 100 can be made of 1400mm long 40mm square steel bars, and the crossbar 110 is welded to the positioning component 100. In this embodiment, two positioning parts 120 are used, and the positioning parts 120 can be made of φ10mm steel bars. The positioning parts 120 are welded to the crossbar 110 to form the positioning component 100. The two positioning parts 120 are parallel, and the distance between the two positioning parts 120 can be 1300±2mm. This structure is exactly the same as the distance between the two process holes on the plastic tailgate, which can be directly used to position the plastic tailgate, which is conducive to the direct assembly of the plastic tailgate with the painting fixture and avoids damage to the plastic tailgate.

[0083] When the spray painting fixture in this embodiment is used to paint the plastic tailgate, the plastic tailgate is laid flat, which effectively reduces local stress compared to hanging spray painting. The on-site installation steps of this flat spray painting fixture are as follows:

[0084] First, insert the first positioning rod 320 or the second positioning rod 330 of the fixed component 300 of the flat-type spray painting fixture into the slot on the production line conveyor track. Then, load the plastic tailgate onto the flat-type spray painting fixture of this embodiment. The positioning member 120 of the fixture passes through the positioning hole on the plastic tailgate. The second support part 220 and the third support part 230 respectively support the edge of the plastic tailgate. Since the second support part 220 and the third support part 230 are both elongated, they can provide a larger support area, effectively reducing the stress. After the plastic tailgate is assembled, spray painting, baking and other operations can be performed.

[0085] It should be noted that in some embodiments of this application, the positioning member 120 extends along the third direction Z, and the positioning member 120 passes through the positioning hole in the third direction Z, that is, the vertical direction. During the painting and baking process of the plastic tailgate, the positioning member 120 is free from gravity, so no deformation problem occurs at the positioning hole. At the same time, the second support part 220 and the third support part 230 contact the edge of the plastic tailgate and support it. They also have a relatively long length along the first direction X, which can match the structural characteristics of the plastic tailgate in the length direction, so as to realize the entire plastic tailgate can be dragged, thus having a large support area and avoiding the problem of deformation near the positioning hole after the plastic tailgate is baked. Therefore, the painting fixture of this application embodiment can achieve a painting qualification rate of over 98% when applied in the painting process, effectively avoiding quality problems such as deformation of the plastic tailgate caused by the painting fixture itself.

[0086] Accordingly, a painting system according to an embodiment of this application includes a painting fixture as described in any of the foregoing embodiments.

[0087] It is understood that the painting system of this application includes all the technical features and effects of the aforementioned painting fixture, which will not be repeated here.

[0088] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
