A spraying fixture for glass edging

Abstract

This invention relates to the field of glass spraying technology, specifically to a spraying fixture for glass edging. The fixture includes a frame, with a spraying device mounted on the outside of the frame. An opening is provided near the bottom on one side of the frame corresponding to the spraying device. A clamp for fixing the glass edging is installed inside the frame. The clamp has a clamping end adapted to the glass edging, used to clamp the glass edging, exposing the edge of the glass edging to the opening. The spraying device sprays the exposed edge of the glass edging. Because only the edge of the glass edging is exposed under the spraying device, while the rest is shielded by the frame and clamp, paint is not sprayed onto non-spraying areas of the glass edging, thus ensuring the spraying quality of the glass edging's edge.

[0009] Furthermore, a handle is provided on the first mounting plate.

[0010] Furthermore, the upper contouring mechanism also includes a gantry support frame fixedly mounted on the platform and a connecting plate slidably connected to the gantry support frame in the vertical direction. The upper contouring component is disposed on the lower surface of the connecting plate, and the second mounting plate of the upper contouring component is connected to the lower surface of the connecting plate.

[0011] Furthermore, the upper contouring mechanism also includes a lifting component fixedly mounted on the gantry support frame and used to drive the upper contouring component to move vertically. The lifting component includes a driving member mounted on the gantry support frame. The movable end of the driving member is connected to the connecting plate.

[0031] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0032] In the description of this invention, it should be understood that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. In the description of this invention, "glass" can refer to inorganic glass or plastic glass made of organic polymers or other materials. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] In this invention, the edging material can be selected from commonly used automotive glass edging materials such as polyurethane (PU), thermoplastic elastomer (TPE), ethylene propylene diene monomer (EPDM), polyvinyl chloride (PVC), and polypropylene (PP). Alternatively, the glass can also be laminated glass composed of multiple glass sheets stacked together.

[0034] Please refer to Figure 1 and Figure 3 As shown, the present invention discloses a glass edging spraying fixture, comprising a frame 1, a spraying device (not shown) disposed on the outside of the frame 1, an opening 11 provided on the side of the frame 1 corresponding to the spraying device near the bottom, a clamp 2 for fixing the glass edging installed inside the frame 1, the clamp 2 having a clamping end adapted to the glass edging, the clamping end being used to clamp the glass edging, so that the edge of the glass edging is exposed at the opening 11, and the spraying device spraying the edge of the glass edging exposed at the opening 11.

[0035] As can be seen from the above description, the beneficial effects of the present invention are as follows: the clamp 2 holds the glass edging within the frame 1, and only the edge of the glass edging is exposed at the opening 11 of the frame 1. During the spraying process, the spraying device outside the frame 1 sprays the edge of the glass edging through the opening 11. Since only the edge of the glass edging is exposed under the spraying device, and the rest is shielded by the frame 1 and the clamp 2, paint will not be sprayed onto the non-spraying areas of the glass edging, thus ensuring the spraying quality of the edge of the glass edging.

[0036] Please refer to Figure 1 and Figure 3 As shown, the frame 1 further includes a platform 12, and the clamp 2 includes a lower contouring mechanism 21 and an upper contouring mechanism 22 for clamping the glass edge. The lower contouring mechanism 21 is detachably and fixedly connected to the platform 12, and the upper contouring mechanism 22 is located above the lower contouring mechanism 21 and can move in the vertical direction.

[0037] As described above, the workers can first place the glass edging to be sprayed on the lower contouring mechanism 21 on the platform 12 for positioning and installation. Then, the upper contouring mechanism 22 moves downward in the vertical direction and cooperates with the lower contouring mechanism 21 to press the glass edging tightly, so that only the edge of the glass edging is exposed at the opening 11, thus preventing the paint from being sprayed onto the non-spraying area of ​​the glass edging.

[0038] Please refer to Figure 2 and Figure 4As shown, the lower contouring mechanism 21 further includes a first mounting plate 211 and a lower contouring support block 212. The first mounting plate 211 is detachably and fixedly connected to the platform 12, and the lower contouring support block 212 is located at the opening 11 of the frame 1 and connected to the first mounting plate 211.

[0039] The upper contouring mechanism 22 includes an upper contouring component, which includes a second mounting plate 221 and an upper contouring pressure block 222. The upper contouring pressure block 222 is connected to the second mounting plate 221, and the second mounting plate 221 is movably connected to the platform 12 above it in a vertical direction. The upper contouring pressure block 222 is located directly above the lower contouring support block 212. The upper contouring pressure block 222 can move downward in a vertical direction and cooperate with the lower contouring support block 212 to form the clamping end.

[0040] As described above, the lower profile support block 212 located at the opening 11 of the frame 1 cooperates with the upper profile pressure block 222 to form the clamping end of the clamp 2. This clamping end can better fit with the glass edging and further avoid paint contamination of the non-sprayed areas of the glass edging.

[0041] Please refer to Figure 2 As shown, preferably, one end of the lower contour support block 212 has a lower contour groove that matches the glass edging, and the other end of the lower contour support block 212 is connected to the first mounting plate 211. More preferably, the lower contour support block 212 is connected to the first mounting plate 211 using an L-shaped connecting plate 9. The L-shaped connecting plate 9 is provided with an elongated hole 10, and the lower contour support block 212 uses the elongated hole 10 to adjust its distance relative to the first mounting plate 211 in the horizontal and / or vertical directions.

[0042] Please refer to Figure 4 As shown, preferably, one end of the upper molding block 222 has an upper molding groove that matches the glass edging, and the other end of the upper molding block 222 is connected to the second mounting plate 221. More preferably, the upper molding block 222 is L-shaped, and the upper molding block 222 is also provided with an elongated hole 10. The upper molding block 222 uses the elongated hole 10 to adjust its horizontal distance relative to the second mounting plate 221.

[0043] As described above, the shapes of the lower and upper molding grooves can be adjusted according to the glass edging to be clamped, thus adapting to different types of glass edging products. The upper molding pressure block 222 and the lower molding support block 212 are made of POM material to prevent the glass edging from being damaged or deformed, thus affecting the coating quality.

[0044] Please refer to Figure 3 As shown, the upper contouring mechanism 22 further includes a gantry support frame 223 fixedly mounted on the platform 12 and a connecting plate 224 slidably connected to the gantry support frame 223 in the vertical direction. The upper contouring component is disposed on the lower surface of the connecting plate 224, and the second mounting plate 221 of the upper contouring component is connected to the lower surface of the connecting plate 224.

[0045] As can be seen from the above description, the gantry support frame 223 facilitates the quick disassembly and installation of the upper contouring components.

[0046] Please refer to Figure 1 and Figure 3 As shown, the upper contouring mechanism 22 further includes a lifting assembly fixedly mounted on the gantry support frame 223 and used to drive the upper contouring component to move vertically. The lifting assembly includes a driving member 227 mounted on the gantry support frame 223. The movable end of the driving member 227 is connected to the connecting plate 224, and the driving member 227 drives the upper contouring component to move vertically via the connecting plate 224. Preferably, the driving member 227 is a cylinder.

[0047] As can be seen from the above description, this configuration allows for controllable overall movement of the upper contouring component in terms of speed and stroke, and the upper contouring mechanism 22 has the advantages of optimized structure and high degree of automation.

[0048] Please refer to Figure 1 and Figure 3 As shown, the upper contouring mechanism 22 further includes a guide component that moves in the vertical direction. The guide component includes a slide rail 225 that is fixedly mounted on two columns of the gantry support frame 223 and extends in the vertical direction, and a slider 226 connected to the slide rail 225. The two ends of the connecting plate 224 are respectively connected to the slider 226.

[0049] As can be seen from the above description, this setting method can effectively guide the upper molding component, ensure the movement accuracy of the upper molding block 222, and thus ensure the accuracy of the upper molding block 222 moving to the glass edge, resulting in structural optimization.

[0050] Please refer to Figure 1 , Figure 3 and Figure 4 As shown, the connecting plate 224 is further connected to the second mounting plate 221 via a snap-fit ​​3.

[0051] As can be seen from the above description, the upper copying component can be quickly replaced by the buckle 3, and the buckle 3 can lock the upper copying component to ensure the stable operation of the upper copying mechanism 22.

[0052] Please refer to Figures 1 to 4 As shown, both the platform 12 and the connecting plate 224 are provided with positioning pins 4, and both the first mounting plate 211 and the second mounting plate 221 are provided with positioning holes 5 that cooperate with the positioning pins 4.

[0053] As described above, the cooperation between the positioning pin 4 and the positioning hole 5 can help workers quickly install the upper copying component onto the connecting plate 224 and the lower copying mechanism 21 onto the platform 12.

[0054] Please refer to Figure 1 and Figure 2 As shown, the lower contouring mechanism 21 further includes a glass support block 6, which is disposed on the first mounting plate 211. Preferably, the top of the glass support block 6 is provided with a positioning groove 61 for use with the glass nail post.

[0055] As described above, the glass support block 6 is used to support the glass edging product, eliminating the need for workers to manually support it. Furthermore, the insertion of the nails on the glass into the positioning groove 61 helps workers quickly position the glass edging product on the first mounting plate 211.

[0056] Please refer to Figure 1 and Figure 2 As shown, the first mounting plate 211 is further provided with weight reduction holes 7.

[0057] As can be seen from the above description, the weight reduction hole 7 can reduce the weight of the first mounting plate 211, reduce the burden on workers to carry the lower copying mechanism 21, and improve production efficiency.

[0058] Please refer to Figure 1 and Figure 2 As shown, the first mounting plate 211 is further provided with a handle 8.

[0059] As can be seen from the above description, the handle 8 facilitates the handling of the lower copying mechanism 21 and enables workers to quickly assemble and disassemble the lower copying mechanism 21 on the platform 12.

[0060] The working principle of the glass edging spraying fixture of the present invention is as follows: During the spraying process, the lower contouring mechanism 21 is first installed on the platform 12, and the upper contouring component is installed on the connecting plate 224. At this time, the upper contouring pressure block 222 is located directly above the lower contouring support block 212. Then, the operator places the glass edging product on the lower contouring mechanism 21 for positioning and installation, and makes the lower contouring support block 212 abut against the glass edging. Then, the cylinder drives the connecting plate 224 to drive the upper contouring pressure block 222 to press the glass edging tightly, so that only the edge of the glass edging is exposed at the opening 11. Then, the spraying device located outside the frame 1 can spray the edge of the glass edging exposed at the opening 11. Since the glass edging is only exposed under the spraying device at the edge, and the rest is blocked by the frame 1 and the clamp 2, the paint will not be sprayed onto other areas of the glass edging, thus ensuring the spraying quality of the edge of the glass edging.

[0061] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
