Description

Technical Field

[0001] The present application relates to the technical field of hardware processing, and in particular to a spraying device suitable for special-shaped hardware products. Background Art

[0002] Hardware products refer to tools made of gold, silver, copper, iron, tin and other metals through processing and casting. They are used to fix things, process things, and decorate. In order to ensure the aesthetics and surface finish, the hardware products are usually sprayed on the outside, which also has an anti-rust effect. When spraying hardware products, it is usually done manually. Manual spraying leads to low spraying efficiency and uneven spraying, which reduces the aesthetics and protectiveness of the hardware products.

[0003] In order to solve the above problems, a Chinese invention patent publication number: CN112892930A provides an omnidirectional spraying device that can ensure uniformity when spraying hardware. The spraying device can only rotate around the hardware product for spraying, wherein the clamp is covered by the clamp in the area where the hardware product is fixedly clamped, resulting in the spraying device being unable to spray in place, leaving a large number of blank areas of the hardware product that cannot be sprayed. Even if the fixed position is changed for clamping and spraying again, the coating will be damaged because the paint is not dry after spraying. If spraying again after the paint is dry, it will also lead to reduced time efficiency and coating stratification. It is also unable to adapt to the surface of special-shaped hardware, and the clamping and fitting area is small and not stable enough, and it is easy to fall and shake. Summary of the invention

The abutment plate has a small area and covers a small area. The paint sprayed in the spraying mesh will penetrate into the surface gap between the abutment plate and the hardware product when flowing on the surface of the hardware product, thereby further improving the spraying effect and the spraying efficiency of the special-shaped hardware products.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0049] The embodiments of the present application provide a spraying device suitable for special-shaped hardware products, which can solve the problems that existing spraying equipment cannot adapt to the surface of special-shaped hardware, the clamping fitting area is small and not stable enough, it is easy to fall and shake, and the area where the clamp is fixed to clamp the hardware product is covered by the clamp, resulting in the spraying equipment being unable to spray in place, leaving a large number of blank areas on the hardware product that cannot be sprayed.

[0050] See also Figure 1-11 As shown, in an embodiment of the present application, a spraying device suitable for special-shaped hardware products is provided, comprising:

[0051] A spray fixing mechanism, the spray fixing mechanism includes a fixing mechanism that can be adapted to different special-shaped hardware surfaces for fixing and clamping and a spraying mechanism for the spray fixing mechanism coverage area, and there are two spray fixing mechanisms that are arranged opposite to each other;

[0052] The base mechanism includes a hollow fixed platform 1 and two support seats 5 respectively arranged on both sides of the fixed platform 1. A paint box 3 for driving a spraying mechanism to spray is arranged in the fixed platform 1, and two spraying fixing mechanisms are respectively arranged on the two support seats 5.

[0053] Special-shaped hardware products are clamped by two fixing mechanisms, and the clamping parts of the fixing mechanisms can be fitted and abutted against the surface of the special-shaped hardware products, so that the contact area of ​​the hardware products of different shapes when being clamped is increased, and the clamping is more stable, thereby preventing the special-shaped hardware products from falling due to the impact force during spraying due to the irregular shapes of the clamping angles and clamping points. Conventional clamps cannot adapt to hardware products of various shapes, thereby improving the adaptability of the spraying equipment when clamping the hardware products, and improving the stability of the hardware products when the spraying equipment is spraying.

[0054] The spraying mechanism enables the fixing mechanism to not only have the function of fixing and clamping the hardware products, but also have the function of spraying the hardware products, so that the area covered by the fixing mechanism when clamping the hardware products can be sprayed, avoiding the area covered by the fixing mechanism failing to be sprayed in place when the hardware products are sprayed as a whole, resulting in blank spaces, reducing the aesthetics of the hardware products and reducing the quality of the products.

[0055] In some optional embodiments, see Figure 1-11 As shown, in the spraying device suitable for special-shaped hardware products, the fixing mechanism includes a first connecting tube 8, a connecting block 91 arranged on one side of the first connecting tube 8, and a clamp assembly 10 arranged on the side of the connecting block 91 away from the first connecting tube 8 for adapting to different special-shaped hardware surfaces. There are several clamp assemblies 10, and the several clamp assemblies 10 are arranged at equal intervals along the length direction of the connecting block 91.

[0056] The third cylinder 6 is used to bring the two fixing mechanisms closer to each other and clamp the hardware product, so that the clamp assembly 10 abuts against the surface of the hardware product. Several clamp assemblies 10 form several contact points, so that the fixing mechanism abuts and clamps the hardware product at multiple points, thereby improving the fixing effect.

[0057] In this embodiment, the clamp assembly 10 includes a second connecting tube 101 arranged on the connecting block 91, a fixing block assembly arranged on the side of the second connecting tube 101 away from the connecting block 91, and a first driving mechanism arranged on the second connecting tube 101 for changing the orientation of the fixing block assembly to fit the surface of the special-shaped hardware.

[0058] In this embodiment, the fixing block assembly includes a first fixing block 106 connected to the second connecting tube 101 and two second fixing blocks 104 respectively arranged on both sides of the first fixing block 106;

[0059] The two second fixing blocks 104 are respectively connected to the first fixing blocks 106 via the articulated ball assembly 105 , and the first driving mechanism has two first driving mechanisms, which respectively drive the two second fixing blocks 104 .

[0060] When the clamp assembly 10 gradually approaches the hardware product, the first fixing block 106 first abuts against the hardware product, and then the position of the second fixing block 104 is adjusted by the first driving mechanism so that the second fixing block 104 fits the hardware product.

[0061] In this embodiment, the first fixing block 106 and the second fixing block 104 both include a shell 1061 and a plurality of adapter columns 1062 disposed on a side of the shell 1061 away from the second connecting tube 101, and the plurality of adapter columns 1062 are arranged at equal intervals along the length direction of the shell 1061;

[0062] The shell 1061 is a hollow structure, and a plurality of spray mesh holes 1063 are provided on a side of the shell 1061 away from the second connecting tube 101. The plurality of spray mesh holes 1063 are respectively located between every two adapter columns 1062. The articulated ball assembly 105 is a hollow structure with openings at both ends. The articulated ball assembly 105 is interconnected with the first fixed block 104 and the second fixed block 106.

[0063] The articulated ball assembly 105 includes two articulated balls and a ball rod arranged between the two articulated balls to connect the two articulated balls, wherein both ends of the first fixed block 106 are provided with a first ball groove for placing the articulated ball, and the second fixed block 104 is provided with a second ball groove for placing the articulated ball at one end close to the first fixed block 106, and the second fixed block 104 can be rotated around the first fixed block 106 through the articulated ball assembly 105. Because the articulated ball assembly 105 is a double articulated ball, the second fixed block 104 can be rotated and displaced around the directions of the two articulated balls at the same time, so that the second fixed block 104 can be adjusted to a suitable angle, so that each second fixed block 104 can be adjusted to different directions to adapt to the angles of various contact parts of special-shaped hardware products.

[0064] The first fixed block 104 and the second fixed block 106 are provided with connecting holes at one end connected to the articulated ball assembly 105, so that the articulated ball assembly 105 and the first fixed block 104 and the second fixed block 106 are interconnected, so that the paint in the paint box 3 can be transported from the first fixed block 106 to the second fixed block 104, so that the second fixed block 104 can spray the clamped and covered part.

[0065] In this embodiment, the adapter column 1062 includes a column 10621 disposed on the housing 1061 , a universal ball seat 10622 disposed on a side of the column 10621 away from the housing 1061 , and an abutment plate 10623 disposed on the universal ball seat 10622 .

[0066] When the first fixing block 106 and the second fixing block 104 are adjusted to a proper angle and contact the special-shaped hardware product, the abutment plate 10623 abuts against the special-shaped hardware product at the same time, and the abutment plate 10623 is connected to the universal ball seat 10622. When the second fixing block 104 and the first fixing block 106 contact the surface of the special-shaped hardware product, the abutment plate 10623 will change its angle through the universal ball seat 10622 along with the angle of the surface contact point of the special-shaped hardware product to adapt to the surface of the special-shaped hardware product, so that the fixing mechanism can generate several abutment points through several adapter columns 1062 to further enhance the fixing strength.

[0067] When the special-shaped hardware products are being sprayed, the paint box 3 simultaneously conveys the paint to the delivery pipe 41, and then the delivery pipe 41 delivers the paint to the first fixed block 106 and the second fixed block 104, and the paint is sprayed out from the spraying mesh 1063, and the area covered by the first fixed block 104 and the second fixed block 104 is sprayed, and the abutment plate 10623 has a small area and covers a small area. When the paint sprayed in the spraying mesh 1063 flows on the surface of the hardware products, it will penetrate into the surface gap between the abutment plate 10623 and the hardware products, thereby further improving the spraying effect and the spraying efficiency of special-shaped hardware products.

[0068] Among them, the adapter column 1062 can also be a hollow structure with openings at both ends, and the universal ball seat 10622 can also be a hollow structure with openings at both ends, so that the adapter column 1062 is connected to the first fixed block 106 and the second fixed block 104, and the abutment plate 10623 can be a mesh plate structure, that is, the paint can be transported to the abutment plate 10623 through the adapter column 1062 and sprayed out, and the position covered by the abutment plate 10623 is sprayed, thereby further enhancing the spraying effect.

[0069] In some optional embodiments, see Figure 1-11As shown, in the spraying device suitable for special-shaped hardware products, the first driving mechanism includes a first cylinder 102 arranged on the second connecting cylinder 101, a connecting rod assembly arranged between the first cylinder 102 and the second fixed block 104, and a guide assembly arranged on the second connecting cylinder 101 for guiding the connecting rod assembly. The guide assembly includes a slide rail 103 and a slider 108 adapted to the slide rail 103, the piston end of the first cylinder 102 is connected to the slider 108, the connecting rod assembly includes a first connecting rod 107 and a second connecting rod 109 hinged to each other, the first connecting rod 107 is connected to the slider 108, and the second connecting rod 109 is hinged to the second fixed block 104.

[0070] When the second fixed block 106 needs to change its angle, the piston rod on the first cylinder 102 extends or retracts to drive the slider 108 to slide on the slide rail 103, and the slider 108 drives the first connecting rod 107 and the second connecting rod 109 to move forward or backward, so that the second fixed block 104 rotates to adjust the angle as the first connecting rod 107 and the second connecting rod 109 move forward or backward.

[0071] The slide rail 103 is a track with a T-shaped slide groove so that the slider 108 will not fall off.

[0072] In some optional embodiments, see Figure 1-11 As shown, in the spraying device suitable for special-shaped hardware products, the connecting block 91 is a hollow structure, and the end of the second connecting tube 101 away from the clamp assembly 10 is inserted into the connecting block 91. The second connecting tube 101 is a hollow structure, and the end of the second connecting tube 101 close to the shell 1061 is interconnected with the shell 1061, and a fixing rod 92 is connected between several second connecting tubes 101.

[0073] In this embodiment, the first connecting tube 8 is a hollow structure, and a partition 13 is provided inside the first connecting tube 8. The partition 13 divides the interior of the first connecting tube 8 into a first cavity 15 and a second cavity 16.

[0074] The paint box 3 is provided with a delivery pipe 41, one end of which passes through the fixing platform 1 and the first connecting tube 8 in sequence, and extends into the connecting block 91 along the second cavity 16 to connect and communicate with one of the second connecting tubes 101;

[0075] The delivery pipe 41 and the remaining second connecting tubes 101 are connected and communicated with each other through a branch pipe 42 .

[0076] In this embodiment, a second cylinder 12 is disposed in the first cavity 15, and a driving rod 14 is disposed between the piston end of the second cylinder 12 and the fixed rod 92;

[0077] A spraying robot arm 11 is disposed on one side of the fixing platform 1 . The fixing mechanism further includes a third cylinder 6 disposed on the supporting seat 5 . A push rod 7 is disposed between the piston end of the third cylinder 6 and the first connecting tube 8 .

[0078] A through hole is opened on the connecting block 91, and several second connecting tubes 101 are inserted into the connecting block 91 through the through hole, and then a fixing rod 92 is fixedly connected between every two second connecting tubes 101, so that the several second connecting tubes 101 are connected as a whole. When the two fixing mechanisms are pushed to clamp the hardware products through the third cylinder 6, the second connecting tubes 101 connected to each other as a whole can also be pushed by the second cylinder 12, driving the clamp assembly 10 to fine-tune the clamping of the hardware products again, so that the clamping force is more stable, and the abutment plate 10623 is changed to better fit the surface of the hardware products.

[0079] The delivery pipe 41 may be a hose, and its length is sufficient to allow the second cylinder 12 and the third cylinder 6 to operate to the maximum range, such as Figure 1-4 As shown, the non-straight state of the delivery tube 41 has a margin for extension, avoiding the inconvenience of extension caused by the entire rigid tube.

[0080] The delivery pipe 41 may also be extended by a combination of a hard pipe and a corrugated pipe, or a combination of a hard pipe and a soft pipe, so as to adapt to the second cylinder 12 and the third cylinder 6 under different ranges.

[0081] The spraying robot arm 11 is used to spray the hardware products in the unblocked area in multiple directions.

[0082] Working principle and process of this application:

[0083] When it is necessary to spray hardware products, the third cylinder 6 drives the fixing mechanism to initially clamp the hardware products, and then the second cylinder 12 is used to fine-tune and clamp the hardware products again. At the same time, the first cylinder 102 is used to adjust the angle of the second fixing block 104 so that the abutment plate 10623 on the second fixing block 104 abuts against the surface of the hardware product, and when the abutment plate 10623 abuts, the abutment plate 10623 adaptively changes its angle through the universal ball seat 10622 to adapt to the surface of the hardware product, and then the paint box 3 delivers the paint, which is delivered to each second connecting cylinder 101 through the delivery pipe 41 until it is sprayed from each spray mesh 1063, so that the area covered by the fixing mechanism is sprayed in place to reduce the blank area.
