[0002] In actual production and processing, it is usually necessary to perform sandblasting on workpieces to meet production requirements. At present, a spray gun is usually used to sandblast workpieces. However, in traditional sandblasting, a single spray gun is used to sandblast workpieces. Since it is necessary to sandblast the front, back, and side surfaces of the workpiece, it is necessary for workers to load and unload the workpiece three times to adjust the relative position between the workpiece and the spray gun, so as to sandblast the front, back, and side surfaces of the workpiece, resulting in high labor intensity and low operation efficiency for workers. In addition, due to the need for workers to frequently load and unload the workpiece, there are differences in the placement position of each workpiece, resulting in unstable sandblasting quality and affecting the sandblasting yield. Summary of the Utility Model

[0064] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0065] Please refer to Figure 1 In the embodiments of the present application, a spray gun mechanism 100 is provided. Please refer to Figure 2 simultaneously. The spray gun mechanism 100 is used to spray abrasive materials onto the first surface 201 of the workpiece 200, the second surface 202 opposite to the first surface 201, and the outer side surface 203 connecting the first surface 201 and the second surface 202. Among them, the workpiece 200 may be a middle frame, and the first surface 201 and the second surface 202 may be the front and back surfaces of the middle frame respectively. It can be understood that the workpiece 200 may also be other objects having a first surface 201, a second surface 202, and an outer side surface 203, and the embodiments of the present application do not make specific limitations thereto.

[0066] The spray gun mechanism 100 includes a motion assembly 10, a connecting member 20, and a spray gun assembly 30.

[0067] The connecting member 20 is connected to the moving component 10 to move under the drive of the moving component 10. The spray gun assembly 30 is connected to the connecting member 20 and moves synchronously with the connecting member 20. It can be understood that during actual use of the spray gun mechanism 100, the moving component 10 can drive the connecting member 20 and the spray gun assembly 30 to move, so that the spray gun assembly 30 corresponds to the workpiece 200. Alternatively, the workpiece 200 can also be driven by an external mechanism (not shown in the figure) to move so that the workpiece 200 corresponds to the spray gun assembly 30. Correspondingly, in the above two cases, after the workpiece 200 corresponds to the spray gun assembly 30, the moving component 10 drives the connecting member 20 and the spray gun assembly 30 to move, and at the same time the external mechanism drives the workpiece 200 to perform a profiling movement, so that the spray gun assembly 30 performs a comprehensive sandblasting treatment on the profiled workpiece 200, where sandblasting can be understood as spraying abrasive materials.

[0068] The spray gun assembly 30 includes a first spray gun 301 with an adjustable spraying angle, a second spray gun 302 with an adjustable spraying angle, and a third spray gun 303. The first spray gun 301 is used to spray abrasive materials towards the first surface 201, the second spray gun 302 is used to spray abrasive materials towards the second surface 202, and the third spray gun 303 is used to spray abrasive materials towards the outer side surface 203. The first spray gun 301 and the second spray gun 302 are symmetrically arranged, and the first spray gun 301 and the second spray gun 302 are located on the same side of the third spray gun 303. It can be understood that the first spray gun 301, the second spray gun 302, and the third spray gun 303 generally form a Y shape. The spraying angles of the first spray gun 301 and the second spray gun 302 can both be adjusted to facilitate the adaptive adjustment of the spray gun assembly 30 according to different workpieces 200.

[0069] When the above spray gun mechanism 100 performs sandblasting on the workpiece 200, the moving component 10 drives the connecting member 20 and the spray gun assembly 30 to move, so that the spray gun assembly 30 corresponds to the workpiece 200, that is, the first spray gun 301 of the spray gun assembly 30 is located obliquely above the first surface 201 and corresponds to the first surface 201, the second spray gun 302 is located obliquely below the second surface 202 and corresponds to the second surface 202, the third spray gun 303 is located on the front side of the outer side surface 203 and corresponds to the outer side surface 203. The first spray gun 301 sprays abrasive materials towards the first surface 201, the second spray gun 302 sprays abrasive materials towards the second surface 202, and the third spray gun 303 sprays abrasive materials towards the outer side surface 203, thereby realizing simultaneous sandblasting of three different surfaces of the workpiece 200. It can be understood that when the workpiece 200 performs a profiling movement, the moving component 10 drives the connecting member 20 and the spray gun assembly 30 to perform an adaptive movement to facilitate the comprehensive sandblasting treatment of the workpiece 200 by the spray gun assembly 30.

[0070] In this embodiment, the number of the spray gun assemblies 30 is multiple. The multiple spray gun assemblies 30 are arranged at intervals on the connecting member 20, and the multiple spray gun assemblies 30 move synchronously. In this way, by providing the multiple spray gun assemblies 30, the spray gun mechanism 100 can perform sandblasting on multiple workpieces 200 simultaneously. Exemplarily, the number of the spray gun assemblies 30 can be five. It can be understood that in other embodiments, the number of the spray gun assemblies 30 can also be less or more, and the embodiments of the present application do not make specific limitations here.

[0071] In this embodiment, the adjustable range of the spraying angle of the first spray gun 301 and the adjustable range of the spraying angle of the second spray gun 302 are both 0° to 90°. In this way, by limiting the adjustable range of the spraying angle of the first spray gun 301 and the adjustable range of the spraying angle of the second spray gun 302, when the spray gun assembly 30 is actually used, the spraying angles of the first spray gun 301 and the second spray gun 302 can be adaptively adjusted according to the type of the workpiece 200, which is beneficial to improving the versatility of the spray gun mechanism 100.

[0072] In this embodiment, the structures of the first spray gun 301, the second spray gun 302 and the third spray gun 303 are substantially similar. The first spray gun 301, the second spray gun 302 and the third spray gun 303 all include a main body 3001 and a spray head 3002. The main body 3001 has a sand inlet 3003, an air inlet 3004 and a sand outlet 3005. The sand inlet 3003 is used to communicate with an external sand supply mechanism (not shown in the figure), the air inlet 3004 is used to communicate with an external air supply mechanism (not shown in the figure), the spray head 3002 is communicated with the sand outlet 3005, and the spray head 3002 is used to spray the sand material mixed with gas ejected from the sand outlet 3005. Among them, the main body 3001 can be made of aluminum material, and the spray head 3002 can be a boron carbide nozzle, and the boron carbide nozzle is more durable. In this way, by providing the specific structures of the first spray gun 301, the second spray gun 302 and the third spray gun 303 as above, it is beneficial to improve the durability and spraying quality of the first spray gun 301, the second spray gun 302 and the third spray gun 303.

[0073] It can be understood that in this embodiment, each of the first spray gun 301, the second spray gun 302 and the third spray gun 303 is configured with an electro-pneumatic proportional valve (not shown in the figure). The electro-pneumatic proportional valve has functions of air pressure setting, automatic monitoring and automatic compensation, so that the first spray gun 301, the second spray gun 302 and the third spray gun 303 have the function of adjustable pressure, and the versatility of the spray gun assembly 30 is improved.

[0074] In this embodiment, the motion assembly 10 can drive the connecting member 20 and the spray gun assembly 30 to move in two perpendicular directions. Specifically, the motion assembly 10 can include a first linear module (not shown in the figure), a second linear module (not shown in the figure), a base 11, a carriage 12, a first slide rail-slider structure 13, a slide base 14, a second slide rail-slider structure 15, and a connecting arm 16. The base 11 can be arranged on an external structure such as a frame (not shown in the figure). The first slide rail-slider structure 13 is arranged on the base 11. The carriage 12 is connected to the first slide rail-slider structure 13 to be slidably arranged on the base 11 through the first slide rail-slider structure 13. Among them, the number of both the base 11 and the first slide rail-slider structure 13 is two and they correspond one by one. The two bases 11 are arranged at intervals. The carriage 12 is generally in a ring structure. The carriage 12 can move along the base 11 through the first slide rail-slider structure 13. The first linear module is connected to the carriage 12 to drive the carriage 12 to move along the base 11. The second slide rail-slider structure 15 is arranged on the carriage 12. The slide base 14 is a hollow structure. The slide base 14 is connected to the second slide rail-slider structure 15 and sleeved outside the second slide rail-slider structure 15 and the carriage 12. One end of the connecting arm 16 is connected to the slide base 14, and the other end of the connecting arm 16 is connected to the connecting member 20. Among them, the number of both the second slide rail-slider structure 15, the slide base 14, and the connecting arm 16 is two. The second linear module is connected to one or two slide bases 14 to drive the slide base 14 to move along the carriage 12. The moving direction of the slide base 14 is perpendicular to the moving direction of the carriage 12. The extending direction of the first slide rail-slider structure 13 is perpendicular to the extending direction of the second slide rail-slider structure 15. Thus, by setting the specific structure of the above-mentioned motion assembly 10, the motion assembly 10 can drive the connecting member 20 and the spray gun assembly 30 to move in two perpendicular directions.

[0075] It can be understood that in other embodiments, the motion assembly 10 can also be other functional mechanisms that can drive the connecting member 20 and the spray gun assembly 30 to move in two perpendicular directions. For example, it can be a two-axis linear module, or a three-axis linear module, or a robotic arm, etc. The embodiments of the present application do not make specific limitations on this.

[0076] Please refer to Figure 3 and Figure 4, in this embodiment, the spray gun assembly 30 further includes a first connecting rod 304, a first adjusting member 305, and a second adjusting member 306. The first connecting rod 304 is vertically connected to the connecting member 20. The first adjusting member 305 and the second adjusting member 306 are arranged at intervals, and both the first adjusting member 305 and the second adjusting member 306 are movably arranged on the first connecting rod 304. The first adjusting member 305 is located directly above the second adjusting member 306. The first spray gun 301 is rotatably arranged on the first adjusting member 305, and the second spray gun 302 is rotatably arranged on the second adjusting member 306. Thus, by providing the above-mentioned first connecting rod 304, first adjusting member 305, and second adjusting member 306, on the one hand, the first spray gun 301 is rotatably arranged on the first adjusting member 305, and the second spray gun 302 is rotatably arranged on the second adjusting member 306, realizing the function of adjustable spraying angles of the first spray gun 301 and the second spray gun 302. On the other hand, both the first adjusting member 305 and the second adjusting member 306 are movably arranged on the first connecting rod 304, enabling the first spray gun 301 and the second spray gun 302 to also have the function of moving up and down, further improving the versatility of the spray gun assembly 30. It can be understood that both the first adjusting member 305 and the second adjusting member 306 can be buckled on the first connecting rod 304 and fastened with screws. When it is necessary to adjust the positions of the first adjusting member 305 and the second adjusting member 306, loosen the screws to facilitate adjusting the positions of the first adjusting member 305 and the second adjusting member 306, thereby adjusting the positions of the first spray gun 301 and the second spray gun 302. Tighten the screws to fix the first adjusting member 305 and the second adjusting member 306, thereby fixing the first spray gun 301 and the second spray gun 302.

[0077] In this embodiment, a plurality of first insertion holes 3051 arranged at intervals are formed on the first adjusting member 305. The spray gun assembly 30 further includes a first insertion rod 307 and a first connection seat 308. One end of the first insertion rod 307 is inserted into any one of the first insertion holes 3051, and the other end of the first insertion rod 307 is connected to the first connection seat 308. The first spray gun 301 is arranged on the first connection seat 308. Among them, the first insertion rod 307 can be rotatably inserted into the first insertion hole 3051. When it is necessary to adjust the spraying angle of the first spray gun 301, the angle of the first spray gun 301 can be adjusted by rotating the first insertion rod 307. Among them, the first connection seat 308 can also be buckled on the main body 3001 of the first spray gun 301 and fastened with screws. Thus, by providing the above-mentioned first insertion rod 307 and first connection seat 308, the first spray gun 301 is rotatably arranged on the first adjusting member 305, and by inserting the first insertion rod 307 into different first insertion holes 3051, it is convenient to adjust the position of the first spray gun 301.

[0078] Understandably, in other embodiments, the first connecting seat 308 can also be rotatably connected to the first inserting rod 307. Thus, when it is necessary to adjust the spraying angle of the first spray gun 301, rotating the first connecting seat 308 can adjust the spraying angle of the first spray gun 301, wherein the first inserting rod 307 can be fixedly inserted into the first inserting hole 3051.

[0079] In this embodiment, a plurality of second inserting holes 3061 are provided at intervals on the second adjusting member 306. The spray gun assembly 30 further includes a second inserting rod 309 and a second connecting seat 310. One end of the second inserting rod 309 is inserted into any one of the second inserting holes 3061, the other end of the second inserting rod 309 is connected to the second connecting seat 310, and the second spray gun 302 is disposed on the second connecting seat 310. Wherein, the second inserting rod 309 can be rotatably inserted into the second inserting hole 3061. When it is necessary to adjust the spraying angle of the second spray gun 302, the angle of the second spray gun 302 can be adjusted by rotating the second inserting rod 309. Wherein, the second connecting seat 310 can also be buckled on the body 3001 of the second spray gun 302 and fastened by screws. Thus, by providing the above-mentioned second inserting rod 309 and second connecting seat 310, the second spray gun 302 is rotatably disposed on the second adjusting member 306, and by inserting the second inserting rod 309 into different second inserting holes 3061, it is convenient to adjust the position of the second spray gun 302.

[0080] Understandably, in other embodiments, the second connecting seat 310 can also be rotatably connected to the second inserting rod 309. Thus, when it is necessary to adjust the spraying angle of the second spray gun 302, rotating the second connecting seat 310 can adjust the spraying angle of the second spray gun 302, wherein the second inserting rod 309 can be fixedly inserted into the second inserting hole 3061.

[0081] In this embodiment, the spraying angle and spraying position of the third spray gun 303 can also be adjusted, so as to further improve the versatility of the spray gun assembly 30. Specifically, the spray gun assembly 30 further includes a second connecting rod 311, a third adjusting member 312, a third inserting rod 313 and a third connecting seat 314. The second connecting rod 311 is vertically connected to the connecting member 20 and is arranged at an interval from the first connecting rod 304. The third adjusting member 312 is movably arranged on the second connecting rod 311. The third adjusting member 312 is provided with a plurality of third insertion holes 3121 arranged at intervals. One end of the third inserting rod 313 is inserted into any one of the third insertion holes 3121, and the other end of the third inserting rod 313 is connected to the third connecting seat 314. The third spray gun 303 is arranged on the third connecting seat 314. Wherein, the second connecting rod 311 and the first connecting rod 304 can be centrally connected to a connecting plate 315. The connecting plate 315 is connected to the connecting member 20, so that the spray gun assembly 30 is modularly arranged. The connecting plate 315 can be generally L-shaped. It can be understood that both the second connecting rod 311 and the first connecting rod 304 can be rotatably connected to the connecting plate 315, so as to improve the versatility of the spray gun assembly 30. The second connecting rod 311 and the first connecting rod 304 can be arranged in a staggered manner, so as to make the third spray gun 303, the second spray gun 302 and the first spray gun 301 located in the same plane. Wherein, the connection mode of the third adjusting member 312 and the second connecting rod 311 is substantially the same as the connection mode of the first adjusting member 305 and the first connecting rod 304. The connection mode of the third inserting rod 313 and the third insertion hole 3121 is substantially similar to the connection mode of the first inserting rod 307 and the first insertion hole 3051. The connection mode of the third connecting seat 314 with the third inserting rod 313 and the third spray gun 303 is substantially similar to the connection mode of the first connecting seat 308 with the first inserting rod 307 and the first spray gun 301. Thus, by arranging the above-mentioned second connecting rod 311, third adjusting member 312, third inserting rod 313 and third connecting seat 314, on the one hand, the spraying angle of the third spray gun 303 can be adjusted, and on the other hand, the spraying position of the third spray gun 303 can be adjusted, so as to further improve the versatility of the spray gun assembly 30.

[0082] The spray gun mechanism 100 provided by the embodiment of the present application can realize sandblasting of three different surfaces of the workpiece 200 through the spray gun assembly 30, without frequently loading and unloading to adjust the position of the workpiece 200, reducing the time of loading and unloading, which is beneficial to improving the operation efficiency; since the spray gun mechanism 100 can sandblast three surfaces of the workpiece 200 at the same time without manual frequent loading and unloading, it is beneficial to reduce the labor intensity of the manual work. In addition, since there is no need for manual frequent loading and unloading, the placement position of the workpiece 200 is relatively stable, which is beneficial to improving the sandblasting yield. In addition, through the cooperation of the moving assembly 10 and the profiling movement of the workpiece 200, a comprehensive sandblasting treatment of the workpiece 200 can be realized.
