[0031] The technology of the embodiment of the present application is applied in the development and production of windshield trim spraying equipment in automotive exterior parts to avoid and solve the problem of defective particles caused by friction of the parts. At the same time, the contact area between the fixture and the product is increased to increase the conductivity between the product and the ground, so that the paint in the electrostatic spraying is more efficiently adsorbed on the product.
[0032] Terminology explanation:
[0033] Surface treatment (painting): In this application, it refers specifically to the paint adhesion process of automotive exterior parts, that is, painting (after pre-treatment degreasing and dust removal, robot spray painting, heating and high-temperature baking to solidify the paint film, cooling and drying, etc.);
[0034] Parts: refers to the automobile exterior parts (also called workpieces, products) fixed on the automated painting production line, and in the embodiment of the present application, refers to the windshield trim;
[0035] Product friction: Friction is generated when the product contacts the fixture. During pre-processing and operation, the corners of the fixture are prone to scrape the product to produce debris, which is easily blown or adsorbed onto the product during spraying, resulting in defects.
[0036] Electrostatic spraying: After the paint is atomized by the atomizer, it is charged by a high-voltage generator. At the same time, the product is sprayed with conductive primer and contacts the ground through a fixture, forming a circuit between the paint product and the ground. Most of the paint is adsorbed onto the product, resulting in only partial waste.
[0037] Painting jig (spraying tool): Painting jig (spraying tool, hereinafter referred to as painting jig) is a necessity in the process of product surface treatment. It is used as a "bracket" to fix the product, so as to facilitate the spraying angle of the automated painting robot to place the product. It has certain points of force and support, including support, clamping, top, hook or contour frame and other limit fixing methods. It should be understood that how the jig contacts the product, how to reduce the impact of the painting jig on the product and how to improve the conductive performance of the product so as to make efficient use of the paint are important issues in the electrostatic spraying of automotive exterior parts.
[0038] See also Figures 1 to 4 As shown, an embodiment of the present application discloses a painting jig, which includes a base and a jig body.
[0039] Specifically, the jig body is installed on the base, and the jig body includes a first support structure 210 and a second support structure. The first support structure 210 has a profiling structure, which is used to abut against the bottom surface of the product, and the second support structure has a smooth support portion, which is used to abut against the product. The profiling structure and the support portion are both in contact with the bottom of the product, and the surface of the product to be coated is opposite to the bottom surface of the product. Therefore, the profiling structure and the support portion will not affect the coating effect of the surface of the product to be coated.
[0040] In the embodiment of the present application, the contoured structure and the supporting part are both made of metal, and electrical connection can be achieved with the product through the contoured structure and the supporting part, so that the paint can be sprayed onto the product.
[0041] In the embodiment of the present application, the first support structure 210 has a contoured structure that matches the shape of the bottom surface of the product. The contoured structure can increase the contact area with the product, thereby ensuring the stability of the product; the second support structure has a smooth support portion, which is also used to support the bottom of the product. Since the support portion has a smooth transition structural design, it can effectively reduce the second support structure from scratching the surface of the product and causing an increase in the particle defect rate. At the same time, due to the setting of the contoured structure, the contact area between the fixture body and the product can be increased, thereby improving the conductive performance of the product, and further improving the utilization rate of the coating.
[0042] In some embodiments of this application, please continue to refer to Figure 1 and Figure 2 As shown, the contour structure includes a contour part 211 and a stopper 212. The contour part 211 is arranged in a contour with the bottom surface of the product, and the stopper 212 is arranged on one side of the contour part 211. The stopper 212 is used to limit the movement of the product. In practical applications, the bottom surface of the product has a buckle column, and the stopper 212 can contact the buckle column to limit the product from sliding on the contour structure, thereby playing a role in limiting the position of the product.
[0043] In one possible implementation, see Figure 1 and Figure 3 As shown, the stopper 212 includes a rod, one end of which is connected to the contoured portion 211, and the other end of which is a free end and extends toward an end away from the contoured portion 211. Figure 1 and Figure 3 As shown, the edge of the contoured portion 211 and the rod of the stopper portion 212 form an angle, and the angle can be used to clamp the product to achieve product fixation.
[0044] In some embodiments of the present application, see Figure 1 and Figure 2 As shown, the support portion includes a first support end, and the second support structure includes a first support rod 221. One end of the first support rod 221 is connected to the base, and the other end of the first support rod 221 is bent so that the first support rod 221 forms a smooth first support end at the end close to the product. Since the first support rod 221 is bent at one end for contacting with the product, that is, the part of the first support rod 221 contacting with the product is a smooth structure, so that the first support end can effectively reduce the situation of scraping the product, which helps to ensure product quality.
[0045] In some embodiments of this application, please continue to refer to Figure 1 and Figure 2 As shown, the support portion includes a second support end, and the second support structure includes a second support rod 222, one end of the second support rod 222 is connected to the base, and the other end of the second support rod 222 is bent so that the second support rod 222 forms a smooth second support end at the end close to the product. Since the second support rod 222 is bent at one end for contacting with the product, that is, the part of the second support rod 222 contacting with the product is a smooth structure, so that the second support end can effectively reduce the situation of scraping the product, which helps to ensure product quality.
[0046] In some embodiments of the present application, the angles of the first support end and the second support end with respect to the vertical direction and their own extension directions should be adapted to the bottom surface of the product to increase the contact area between the first support end and the second support end and the product.

[0048] In some embodiments of the present application, see Figures 1 to 4 As shown, a second supporting structure is disposed on at least one side of the first supporting structure 210. In this way, the first supporting structure 210 and the second supporting structure located on one side or both sides can jointly support the product.
[0049] In one possible implementation, see Figures 1 to 4 As shown, second supporting structures are disposed on both sides of the first supporting structure 210 .
[0050] In some embodiments of the present application, see Figure 1 and Figure 2 As shown, the base includes a first crossbar 120, and a plurality of first support structures 210 are arranged at intervals on the first crossbar 120 along the extension direction of the first crossbar 120. Correspondingly, in the extension direction of the first crossbar 120, second support structures are arranged on both sides of each first support structure 210 to support and fix the product during painting.
[0051] The extension direction of the first crossbar 120 is Figure 2 The X direction in .
[0052] In some embodiments of this application, please continue to refer to Figure 1 and Figure 2As shown, the base also includes a base 110, and the base 110 is provided with a plurality of fixing holes 112 at intervals along the extending direction perpendicular to the first cross bar 120. A first connecting rod matching the fixing holes 112 is provided at the bottom of the first cross bar 120, and the first connecting rod is movably connected to the fixing holes 112. In this way, the first cross bar 120 can be moved in the extending direction perpendicular to the first cross bar 120, so as to achieve the purpose of conveniently adjusting the position of the first supporting structure 210.
[0053] Specifically in this embodiment, see Figure 1 and Figure 2 As shown, the base also includes a fixing rod 111, which is a hollow structure defining a fixing hole 112 for inserting the first connecting rod. There are multiple fixing rods 111, and each fixing rod 111 is spaced apart in a direction perpendicular to the extension direction of the first crossbar 120.
[0054] In some embodiments of this application, please continue to refer to Figure 1 and Figure 2 As shown, the base further includes a second crossbar 130 , which is arranged parallel to the first crossbar 120 , and the second supporting structure is installed on the second crossbar 130 .
[0055] In this embodiment, Figure 1 and Figure 2 As shown, the base also includes a second connecting rod, one end of which is connected to the second crossbar 130, and the other end is used to be plugged into the fixing hole 112. In this way, the position of the second support structure can be changed by changing the plug-in position of the second connecting rod, thereby achieving the purpose of conveniently adjusting the position of the second support structure. In this way, the positions of the first support structure 210 and the second support structure can be adjusted according to the specifications and dimensions of the product, which helps to improve the practicality of the coating jig of the embodiment of the present application.
