Description

Technical Field

[0001] This invention relates to an automatic oil spraying mechanism, belonging to the field of stamping equipment technology. Background Technology

[0002] In the stamping process of metal exterior parts, the sheet metal is bent and pressed using dies during the stamping process.

[0017] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Please refer to Figures 1 to 2 An embodiment of this application shows an automatic spraying mechanism, which includes a spraying platform 10, a spraying structure 20, and a three-axis drive assembly 30. The three-axis drive assembly 30 drives the spraying platform 10 and the spraying structure 20 to move, so as to spray the four sides of the board, thereby improving work efficiency.

[0024] The automatic oil spraying mechanism also includes a spraying platform 10. A spraying groove is recessed on the upper surface of the spraying platform 10, and an oil drain hole 12 is provided near the inner wall of the spraying groove. The workpiece is placed inside the spraying groove. During the spraying process, the inner wall of the spraying groove can block and collect splashed oil, preventing it from splashing everywhere. By providing an external receiving and collection device for the oil drain hole 12, excess oil can be recycled and reused through the spraying platform 10, reducing production costs.

[0025] The spraying structure 20 includes three sets of spray heads 21 arranged in a right-angled triangle. The spray head 21 at the acute angle is configured to be close to or away from the spray head 21 at the right angle, and the spray head 21 at the right angle is configured to adjust its spraying direction to intersect or be parallel to the spraying direction of at least one of the two sets of spray heads 21 at the acute angle. All three sets of spray heads 21 are set at an angle, with the spray head 21 at the acute angle tilted towards the spray head 21 at the right angle. This configuration allows two spray heads 21 to spray downwards towards the material during spraying, facilitating the spraying of the sides of the material and washing away burrs or debris. Of course, in other embodiments, the spraying direction of the spray heads 21 can also be set vertically or horizontally, or all three sets of spray heads 21 can be rotated to adjust their spraying direction, which can be set according to spraying requirements and is not specifically limited here.

[0026] The three-axis drive assembly 30 includes an X-axis drive structure 31, a Y-axis drive structure 32, and a Z-axis drive structure 33. The three-axis drive assembly 30 is prior art and will not be described in detail here. In this embodiment, the Y-axis drive structure 32 is fixed to the Z-axis drive structure, and the spraying structure 20 is fixed to the Y-axis drive structure 32. The Y-axis drive structure 32 and the Z-axis drive structure 33 drive the spraying structure 20 along the Y-axis direction (e.g.,...). Figure 1 From the direction represented by the arrow Y) and the Z-axis direction (as shown by...) Figure 1 The spraying structure 20 moves along the Y-axis direction (represented by the middle arrow Z) via the Y-axis drive structure 32 to spray a set of sides of the board. The spraying platform 10 moves along the X-axis direction (e.g., via the X-axis drive structure 31) to move the board along the X-axis direction (e.g., via the direction indicated by the middle arrow Z). Figure 1 Move the middle arrow (in the direction indicated by X) to spray the other set of sides of the board, thereby achieving spraying all four sides of the board.

[0027] Admittedly, in another embodiment, the spraying structure 20 can be driven to move along the X-axis and Z-axis directions respectively by the X-axis drive structure 31 and the Z-axis drive structure 33, and the Y-axis drive structure 32 can drive the spraying platform 10 to move the board along the Y-axis direction. That is, the X-axis drive structure 31 is fixed on the Z-axis drive structure 33, the spraying structure 20 is fixed on the X-axis drive structure 31, and the spraying platform 10 is fixed on the Y-axis drive structure 32, thereby realizing the relative movement of the spraying platform 10 and the spraying structure 20 in the X-axis and Y-axis directions to achieve spraying around the board.

[0028] In another embodiment, the Z-axis drive structure 33 drives the spraying structure 20 to move along the Z-axis direction, and the X-axis drive structure 31 and the Y-axis drive structure 32 drive the spraying platform 10 to move the board material along the X-axis direction and the Y-axis direction respectively; that is, the X-axis drive structure 31 is fixed on the Y-axis drive structure 32, the spraying platform 10 is fixed on the X-axis drive structure 31, and the spraying structure 20 is fixed on the Z-axis drive structure 33. The Z-axis drive structure 33 only controls the lifting and lowering movement of the spraying structure 20, and the X-axis drive structure 31 and the Y-axis drive structure 32 drive the spraying platform 10 to move the board material relative to the spraying structure 20 in the X-axis direction and the Y-axis direction, so as to achieve spraying around the board material.

[0029] In another embodiment, the X-axis drive structure 31, Y-axis drive structure 32, and Z-axis drive structure 33 drive the spraying structure 20 along the X-axis, Y-axis, and Z-axis directions, respectively. That is, the X-axis drive structure 31 is fixed on the Y-axis drive structure 32, the Y-axis drive structure 32 is fixed on the Z-axis drive structure 33, and the spraying platform 10 is fixedly set. The X-axis drive structure 31 and Y-axis drive structure 32 drive the spraying structure 20 to move relative to the spraying platform 10 in the X-axis, Y-axis, and Z-axis directions to achieve spraying around the edges of the board.

[0030] In one embodiment, the spraying structure 20 further includes a pair of telescopic members fixed at their ends and arranged perpendicularly to each other, with three sets of nozzles 21 respectively arranged at the ends and intersection of the pair of telescopic members. By driving the nozzles 21 at the ends to move closer to or further away from the nozzles 21 at the intersection through the telescopic members, the distance between the nozzles 21 at the ends and the nozzles 21 at the intersection can be adjusted to meet the spraying requirements of different sized panels.

[0031] In one embodiment, a rotating structure is provided at the intersection of a pair of telescopic members, and a nozzle 21 is connected to the rotating structure. The rotating structure drives the nozzle 21 at the intersection to rotate 90°, so that the spraying direction of the nozzle 21 at the intersection intersects with the spraying direction of one of the nozzles 21 located at the end. This allows the nozzles 21 located on both sides of the board to be opened simultaneously for spraying when the nozzle 21 moves relative to the board along the X-axis or Y-axis, thereby achieving two relative movements and realizing full spraying of the board around its perimeter.

[0032] In one embodiment, the spraying structure 20 further includes a nozzle mounting base 22, which is configured to adjust the spraying direction of the nozzle 21. To accommodate variations in the thickness and side angles of different materials, the nozzle 21 is fixed to the telescopic member by the nozzle mounting base 22, thereby facilitating the adjustment of the fixing angle of the spraying direction of the nozzle 21 by adjusting the angle of the nozzle mounting base 22. Specifically, the nozzle mounting base 22 can be fixedly connected to the telescopic member by bolts. To adjust the fixing angle of the spraying direction, loosen the bolts, adjust the nozzle mounting base 22, and then tighten the bolts to fix the nozzle mounting base 22. Admittedly, the nozzle mounting base 22 and the telescopic member can also be connected and fixed in other ways, as long as the above-mentioned effect is achieved, and no specific limitation is made here.

[0033] In one embodiment, the rotating structure includes an inverted L-shaped fixing plate 26, a rotary motor 27 fixed to the top of the L-shaped fixing plate 26, and a connecting plate 28 connected to the output shaft of the rotary motor 27. The nozzle 21 is fixed to the connecting plate 28 via a nozzle mounting base 22. The L-shaped fixing plate 26 is inverted and fixed at the intersection of a pair of telescopic members, with one end extending horizontally away from the intersection. The rotary motor 27 is fixed to its top, and the connecting plate 28 is fixed to the output shaft of the rotary motor 27 and located below the L-shaped fixing plate 26. The nozzle 21 is fixed to the connecting plate 28 to facilitate rotation of the nozzle 21 by the rotary motor 27, while avoiding interference with other components.

[0034] In one embodiment, the telescopic component includes a fixed plate 23, a fixed plate 24 slidably connected to the fixed plate 23, and a locking component connected between the fixed plate 23 and the fixed plate 24. The locking component is used to lock or unlock the fixed plate 24. This configuration facilitates adjusting the position of the nozzle 21 by moving the fixed plate 24 relative to the fixed plate 23, and locks the fixed plate 24 by locking the fixed plate 24, preventing the nozzle 21 from shifting during spraying and thus affecting the spraying effect.

[0035] In one embodiment, a guide rail 241 is provided on the fixed plate 23, and a slider 242 is provided on the guide rail 241. The fixed plate 24 is fixed on the slider 242. By setting the guide rail 241 and the slider 242 to cooperate, the relative position of the fixed plate 24 and the fixed plate 23 can be adjusted, and their movement direction can be guided to prevent the height of the nozzle 21 from changing and affecting the spraying angle.

[0036] In one embodiment, the guide rail 241 is provided with locking holes 243, and a locking member is fixed to the fixed plate 24. The locking member is configured to be inserted into or withdrawn from the locking holes 243 to lock or unlock the fixed plate 24. A plurality of locking holes 243 are provided at intervals along the length of the guide rail 241. The movable plate is locked or unlocked by inserting or withdrawing the locking member. The locking and unlocking methods are simple and easy to operate, which helps to improve the adjustment speed and production efficiency.

[0037] In one embodiment, the locking element includes a locking seat 244, a locking pin disposed within the locking seat 244, and a driving member 25 for driving the locking pin to insert into or retract from the locking hole 243. The locking pins are arranged horizontally facing each other, and the driving member 25 is arranged vertically. The two are connected by transmission. By rotating the driving member 25, the locking pin is driven to insert into or retract from the locking hole 243. The transmission method can be gear transmission, linkage mechanism transmission, cam mechanism transmission, etc., which can be set according to requirements and is not specifically limited here.

[0038] This application utilizes a three-axis drive assembly to spray paint onto the sheet material within a painting platform by setting up three sets of nozzles arranged in a right-angled triangle. The nozzle located at the right-angle inflection point is configured with an adjustable spraying angle. This allows two nozzles to spray both sides of the sheet material whenever the nozzle and the sheet material move along the X-axis or Y-axis. Spraying all four sides of the sheet material is achieved with only two movements, and burrs or debris can be washed off the sheet material, improving spraying efficiency and effect. Furthermore, the amount of paint and the spray width can be adjusted according to actual product needs to meet the requirements of automated production lines. In addition, the nozzle located at the acute angle end can be moved closer to or further away from the nozzle located at the right angle end, facilitating the adjustment of the spraying size to accommodate sheet materials of different sizes.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
