Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figure 1-6 A convenient multi-color spray painting fixture includes a support assembly 100 and a film assembly 200 that work together.
[0033] The bracket assembly 100 includes a support assembly 110 and a cover assembly 120;
[0034] The support assembly 110 includes a base plate 111, and a first support rod 112, a second support rod 113 and a third support rod 114 arranged in an isosceles triangle are fixed on the upper end surface of the base plate 111.
[0035] The covering assembly 120 includes a cover plate 121, and a covering rod assembly 122 is fixedly provided on the lower end surface of the cover plate 121. The covering rod assembly 122 includes a plurality of covering rods 123 arranged in a uniform array.
[0036] The film assembly 200 includes a PET film layer 210, an adhesive layer 220 and a release paper layer 230 that are sequentially bonded together from top to bottom. The PET film layer 210 and the adhesive layer 220 are respectively provided with pre-set holes 211 that are vertically penetrating and aligned.
[0037] In the use of this utility model's spray painting fixture, the product to be processed 001 is first placed on the support assembly 110. The product to be processed 001 is stably suspended and supported by the first support rod 112, the second support rod 113, and the third support rod 114 arranged in an isosceles triangle. This support method ensures stability and minimizes the contact area with the product to be processed 001, preventing scratches on its surface. After the product to be processed 001 is stably placed, the upper surface of the product to be processed 001 is covered by the covering assembly 120. By lifting the cover plate 121, multiple evenly arrayed covering rods 123 are aligned and inserted into the preset holes on the upper surface of the product to be processed 001. The preset holes are well covered, and then the surface of the product to be processed 001 is painted with the first color. After the first color painting is completed, the cover plate 121 is lifted to separate the covering rod 123 from the product to be processed 001. Then the film assembly 200 is attached to the product to be processed 001, and the release paper layer 230 is peeled off from the lower end of the adhesive layer 220. The preset holes 211 on the PET film layer 210 and the adhesive layer 220 are aligned with the preset holes on the upper surface of the product to be processed 001, so that the upper surface of the product to be processed 001 is covered except for the preset holes. Then the preset holes are painted with the second color. After the second color painting is completed, the PET film layer 210 and the adhesive layer 220 are peeled off and separated from the product to be processed 001, thereby completing the multi-color painting operation on the upper surface of the product to be processed.
[0038] During use, this utility model spray painting fixture provides stable and reliable support for the product 001 to be processed through the support assembly 100. Through precise adjustment and customized clamping mechanism, the support assembly 100 can adapt to products of different shapes and sizes, ensuring that the product will not shift or shake during the spraying process. This not only improves the quality of the spray painting but also reduces paint waste caused by product movement. The film assembly 200 allows the operator to quickly and accurately cover areas that do not need to be painted. It is easy to operate, making the installation and removal process quick and simple, while ensuring the accuracy of the masking boundary, thereby improving the appearance quality of the final product. Since there is no need to disassemble and reassemble the fixture itself, the operator can complete the product preparation and spraying work in a short time. This design greatly shortens the production cycle and improves work efficiency.
[0039] In this embodiment of the utility model, the upper end surfaces of the first support rod 112 and the second support rod 113 are respectively provided with a first inclined surface 115 and a second inclined surface 116 that slopes downwards to the rear, and the upper end surface of the third support rod 114 is provided with a third inclined surface 117 that slopes downwards to the front.
[0040] By setting the first inclined surface 115, the second inclined surface 116, and the third inclined surface 117 at different angles, additional support force can be provided in multiple directions, making the entire support structure more stable. This multi-point contact method can effectively disperse the pressure acting on the product, avoiding product deformation or slippage due to excessive force at a single point. Different inclined surfaces can be adjusted according to the specific geometry of the product to ensure good support even when facing irregular or curved products. This not only increases the contact area but also makes the fit between the fixture and the product tighter, reducing gaps. By rationally designing the angle and position of each inclined surface, the pressure applied by the support structure can be more evenly distributed on the product surface, reducing wear on the product surface.
[0041] In this embodiment of the utility model, the first support rod 112 and the second support rod 113 are located at both ends of the base of an isosceles triangle. The top ends of the first support rod 112 and the second support rod 113 are respectively formed with a first insert rod 118 and a second insert rod 119. The first insert rod 118 and the second insert rod 119 are inserted and engaged with the workpiece to be processed.
[0042] Using an isosceles triangle as the basic structure, this shape naturally possesses excellent stability and resistance to deformation. The two sides of the isosceles triangle can evenly distribute the pressure from the top, ensuring that the entire support system will not easily tilt or overturn. The first insert 118 and the second insert 119 are designed to interlock with the workpiece to be processed. This design ensures that the connection between the two is both tight and accurate. This not only improves the positional accuracy of the product during processing but also reduces quality problems that may be caused by slight displacement. The plug-in connection method greatly simplifies the installation and disassembly process of the workpiece to be processed, eliminating the need for complex tools or additional operating steps. Operators can easily insert the workpiece into place and quickly remove it after completing the work, thus improving work efficiency.
[0043] In this embodiment of the utility model, the cover rod assembly 122 includes at least a first cover rod 124 and a second cover rod 125 that are aligned and cooperate with the first insert rod 118 and the second insert rod 119. The lower ends of the first cover rod 124 and the second cover rod 125 are respectively provided with a first insertion hole 126 and a second insertion hole that are inserted and cooperate with the first insert rod 118 and the second insert rod 119.
[0044] This ensures that the first masking rod 124 and the second masking rod 125 can be installed accurately and without error, providing a reliable positioning reference. The entire masking system is closely integrated with the support system, enhancing the stability of the overall structure. Through precise masking, it can effectively prevent paint or coating from splashing onto the preset holes during the spraying process, keeping the product appearance clean and avoiding the trouble of subsequent cleaning work.
[0045] In this embodiment of the utility model, a covering protrusion 128 is fixed on the outer wall of the covering rod 123, and the covering protrusion 128 is aligned and engaged with the hole to be covered on the workpiece to be processed.
[0046] The insertion of the masking bump 128 into the preset hole on the workpiece ensures the accuracy and consistency of the masking position. This alignment method reduces positional deviations caused by manual operation and improves the accuracy of masking. The tight fit between the masking bump 128 and the preset hole prevents spraying or treatment liquid from seeping into areas that do not need to be treated, thus ensuring the surface quality of the product. After the masking bump 128 is inserted into the hole on the workpiece, it not only plays a masking role but also provides additional support points for the entire masking system, enhancing the stability and reliability of the overall structure.
[0047] In this embodiment of the present invention, an inwardly recessed annular groove 129 is provided around the lower end face of the covering protrusion 128;
[0048] The design of the annular groove 129 enhances the fit between the masking protrusion 128 and the preset hole on the workpiece, effectively preventing the spraying material or treatment liquid from leaking through the gap between the masking protrusion 128 and the preset hole, ensuring the absolute cleanliness of the masked area, and improving the surface quality of the product. The annular groove 129 increases the contact area between the masking protrusion 128 and the edge of the preset hole, further stabilizing the masking position and reducing the risk of displacement.
[0049] In this embodiment of the present invention, a first chamfered portion 130 is provided on the periphery of the upper end surface of the covering protrusion 128;
[0050] The first chamfer 130 reduces the contact area between the edge of the cover protrusion 128 and the inner wall of the preset hole, reducing the friction during insertion and removal, making the whole process smoother, and reducing wear on the hole and the cover protrusion 128 itself.
[0051] In this embodiment of the present invention, the cover plate 121 is provided with a plurality of observation windows 131 arranged equidistantly from front to back;
[0052] Multiple equidistant observation windows 131 allow operators to monitor the painting effect on the upper surface of the product 001 without lifting the cover plate 121, which helps to identify and resolve potential problems in a timely manner and improve production efficiency.
[0053] In this embodiment of the utility model, the cover plate 121 is provided with an array of cover rod mounting holes 132, the upper ends of multiple cover rods 123 are respectively inserted into the cover rod mounting holes 132, the inner wall of the cover rod mounting holes 132 is formed with a snap-fit protrusion 133, the upper outer wall of the cover rod 123 is provided with a snap-fit notch 134 that abuts against the snap-fit protrusion 133, and the upper end face of the cover rod 123 is provided with a bolt insertion hole 135.
[0054] The engagement between the snap-fit notch 134 and the snap-fit protrusion 133 makes the installation of the cover rod 123 in the cover rod mounting hole 132 more stable. The engagement between the bolt and the bolt insertion hole 135 makes the cover rod 123 stably fixed on the cover plate 121.
[0055] In this embodiment of the present invention, the openings of the first insertion hole 126 and the second insertion hole are respectively provided with a second chamfer 136;
[0056] The first insertion rod 118 and the second insertion rod 119 are inserted more smoothly into the first insertion hole 126 and the second insertion hole respectively, which plays a good guiding role. Operators can easily insert the insertion rods into place without precise alignment, which significantly improves installation efficiency.
[0057] During the above processing, only the upper surface of the product 001 to be processed is painted; the painting of the lower surface of the product 001 to be processed is completed by subsequent processes.
[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
