DETAILED DESCRIPTION

[0024] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0025] See also Figures 1 to 6 As shown, the present invention discloses an air-blowing dust removal device, which is used for dust removal during the production process of a workpiece 100, so as to achieve dust-free processing. The workpiece 100 of this embodiment is a car dashboard controller housing, including a bottom shell and an upper cover. The bottom shell and the upper cover are dusted by the air-blowing dust removal device to achieve the purpose of dust-free processing. In other embodiments, the workpiece 100 may also be other products that require dust-free processing.

[0026] The air-blowing dust removal device comprises a first housing component 1 and a second housing component 2. The first housing component 1 is arranged on a lifting mechanism 3. The lifting mechanism 3 enables the first housing component 1 to selectively move relative to the second housing component 2, and the first housing component 1 is selectively enclosed with the second housing component 2 under the action of the lifting mechanism 3 to form a closed dust removal bin. A storage table 4 for placing a workpiece 100 is provided in the dust removal bin. The storage table 4 is connected to a base 6 through a flip mechanism 5. The device also comprises an air-blowing component 7 and a dust suction component 8. The air-blowing component 7 is provided with a nozzle 711. The nozzle 711 extends into the dust removal bin for spraying compressed gas to the workpiece 100. The suction nozzle of the dust suction component 8 (the suction nozzle is not shown in the figure) extends into the dust removal bin for sucking granular foreign matter in the dust removal bin. The flip mechanism 5 is used to drive the storage table 4 and the workpiece 100 thereon to flip for multi-angle dust removal.

[0027] It also includes a controller, which is electrically connected to the flipping mechanism 5, the lifting mechanism 3, the air blowing assembly 7 and the dust suction assembly 8. When a workpiece 100 is fixedly placed on the storage table 4, under the control of the controller, the lifting mechanism 3 drives the first shell assembly 1 to move toward the second shell assembly 2 so that the first shell assembly 1 and the second shell assembly 2 are combined to form a closed dust removal bin, the air blowing assembly 7 is started to blow compressed air in the direction of the workpiece 100 to blow the dust on the workpiece 100 away from the workpiece, the dust suction assembly 8 is started to absorb granular foreign matter floating in the dust removal bin, and the flipping mechanism 5 is actuated to cause the storage table and the workpiece 100 thereon to flip back and forth in the direction indicated by the arc arrow to form an angle with the nozzle 711.

[0028] In this example, the air blowing component 7 sprays compressed air and uses the larger airflow pressure of the compressed air to clean the dust adhering to the workpiece. The dust collecting component 8 is a vacuum cleaner, more specifically an industrial vacuum cleaner, which absorbs the dust in the dust removal bin by negative pressure adsorption. In other embodiments, the dust collecting component 8 can also adsorb the dust in the dust removal bin by electrostatic adsorption. Among them, the granular foreign matter mainly refers to the dust blown off the workpiece. In some cases, other foreign matter in the dust removal bin that can be adsorbed by negative pressure is also part of the granular foreign matter.

[0029] By setting up the flip mechanism 5, the workpiece 100 on the storage table 4 can be flipped and air-blown dust removal can be performed at multiple angles, thereby preventing a large number of dust removal dead corners from remaining due to the complex structure of the workpiece, and the closed dust removal bin can collect the cleaned dust inside it, preventing the dust from floating and contaminating other products, and the dust suction component 8 is set to suck away the dust in time, thereby preventing the dust blown off the workpiece 100 from contaminating the workpiece again. The air-blowing dust removal device can be used to perform automated dust removal operations, which is more efficient than manual dust removal, and the flip mechanism 5 can adjust the flip angle and speed of the storage table 4 according to the structure of the workpiece 100, further ensuring the dust removal efficiency.

[0030] The workpiece 100 of this embodiment includes two, the first workpiece 101 and the second workpiece 102 are respectively the bottom shell and the top cover, and the two are assembled to form the above-mentioned automobile instrument panel controller housing. In other embodiments, the workpiece 100 may be only one or more than two, and the type and quantity of the workpiece 100 can be changed according to the actual needs of production.

[0031] In this example, the first workpiece 101 and the second workpiece 102 are placed on the storage table 4 through the tooling plate 103, so that the two workpieces can be dusted at the same time during dust removal, and the dust removal efficiency is high. In other embodiments, the workpieces can also be placed directly on the storage table 4.

[0032] See also Figures 1 to 6As shown, the first housing assembly 1 and the second housing assembly 2 are arranged opposite to each other up and down, the storage table 4 is arranged on the first housing assembly 1, the nozzle 711 of the air blowing assembly 7 is arranged on the second housing assembly 2 and faces the first housing assembly 1, and the suction nozzle of the dust suction assembly 8 is arranged on the first housing assembly 1 and faces the second housing assembly 2. The nozzle 711 of the air blowing assembly 7 and the suction nozzle of the dust suction assembly 8 are arranged opposite to each other up and down, forming a dust removal airflow in the dust removal bin, which can more quickly suck away the dust blown off the workpiece 100 and prevent the dust from contaminating the workpiece again.

[0033] The first housing assembly 1 is a rectangular structure with an opening at the bottom. The inner top surface of the first housing assembly 1 and the side wall near the lifting mechanism 3 are respectively provided with nozzle assemblies 71. Each nozzle assembly 71 includes a plurality of linearly arranged nozzles 711. The nozzle assembly 71 includes a hollow tube 712. A compressed gas connection port 713 is provided at one end of the hollow tube 712. The nozzles 711 are arranged at intervals on the hollow tube 712. High-pressure gas enters the hollow tube 712 through the compressed gas connection port 713 and is then sprayed from the nozzle 711 onto the workpiece 100.

[0034] In order to prevent the workpiece 100 from shifting or falling during the process of turning over and dust removal, the storage table 5 is also provided with a clamping mechanism 9, which is used to press the workpiece 100 in the direction of the storage table 4, so that the workpiece 100 is fixed. The clamping mechanism 9 includes a cylinder 91 arranged on the storage table 4, and a clamping member 92 is provided at the end of the cylinder 91. The clamping member 92 moves in a direction perpendicular to the storage table 4 under the action of the cylinder 91, thereby clamping or loosening the workpiece 100 on the storage table 4. The clamping member 92 of this example includes a connecting rod 921 fixedly arranged at the end of the cylinder 91 and a clamping block 922 arranged at the end of the connecting rod 921, wherein the clamping block 922 is a rubber block to prevent the workpiece 100 from being damaged by excessive clamping force. In addition, in this example, only the first workpiece 101 is clamped by the clamping block 922, and the second workpiece 102 is not easy to fall due to the small matching clearance between the second workpiece 102 and the tooling plate 103, so the clamping block 922 does not act on the second workpiece 102. However, the clamping mechanism 9 is not limited to being pressed on the first workpiece 101 . In other embodiments, the clamping mechanism 9 may also be pressed on the second workpiece 102 , or both the first workpiece 101 and the second workpiece 102 may be pressed on the storage table 4 by the clamping mechanism 9 .

[0035] The flip mechanism 5 includes a rotating shaft 51 arranged below the storage table 4 and a telescopic cylinder 52 arranged on one side of the storage table 4. One end of the telescopic cylinder 52 is connected to the base 6, and the other end of the telescopic cylinder 52 is hinged to one side of the storage table 4, so that a hinge structure is formed at the hinge of the telescopic cylinder 52 and the storage table 4. The rotating shaft 51 and the hinge structure are arranged at intervals, so that the storage table 4 flips around the rotating shaft 51 under the action of the telescopic cylinder 52. The telescopic cylinder 52 in this example is an air cylinder, and one end of the telescopic cylinder 52 is fixedly arranged below the storage table 4 and close to the rotating shaft 51, so that the telescopic cylinder 52 is telescopic in an oblique direction, which is convenient for setting the compressed air supply pipeline for controlling the telescopic cylinder 52 to be extended and retracted in the inner area of ​​the entire air blowing dust removal device, reducing the occupation of its edge, and making the overall structure of the device more concise.

[0036] One side of the storage table 4 is provided with a connecting piece 41 extending toward the outside of the edge of the storage table 4. The telescopic cylinder 52 includes a cylinder body 521 and a piston rod 522 movably connected to the cylinder body 521. The end of the piston rod 522 is hinged to the connecting piece 41, so that the connecting piece 41 and the piston rod 522 form a hinged structure. In this example, the rotating shaft 51 is arranged in the middle part below the storage table 4. When the telescopic length of the telescopic cylinder 52 remains unchanged, the storage table 4 can be flipped at a larger angle, thereby reducing the telescopic range of the telescopic cylinder 52 and the space occupied by the flipping of the storage table 4 while ensuring that the workpiece 100 is fully flipped and dusted. In other embodiments, the rotating shaft 51 and the hinged structure can also be arranged on two opposite edges of the storage table 4.

[0037] The base 6 is provided with a limiting structure, which is arranged on both sides of the rotating shaft 51. There is a certain distance between the top of the limiting structure and the storage table 4. The storage table 4 abuts against the top of the limiting structure as it turns over, so that the turning over of the storage table 4 is limited. Specifically: the limiting structure is a plurality of limiting rods 61 arranged on the base, and the top of the limiting rod 61 is provided with an elastic member 611 to form a buffer for the storage table 4. The limiting rod 61 is an elastic telescopic rod, which will shrink slightly when hit by the storage table 4. In addition to limiting, it can also play a buffering role. The elastic member 611 at the top of the limiting rod 611 is a rubber block, which further buffers the turning over of the storage table 4.

[0038] The present invention further includes a frame (not shown in the figure) to limit the relative position of the first housing assembly 1 and the second housing assembly 2 .

[0039] The workflow of the present invention is as follows: Figures 1 to 6As shown, the tooling plate 103 with the first workpiece 101 and the second workpiece 102 is placed on the storage table 4, and the controller controls the cylinder 91 of the clamping mechanism 9 to contract so that the clamping member 92 is pressed on the first workpiece 101, and the first shell assembly 1 is lowered along with the lifting mechanism 3 to form a dust removal bin with the second shell assembly 2; the controller controls the flipping mechanism 5, the air blowing assembly 7 and the dust suction assembly 8 to start, and the nozzle 711 fixed on the first shell assembly 1 blows air downward, and the telescopic cylinder 52 of the flipping mechanism 5 reciprocates to drive the storage table 4 and the workpiece 100 thereon to move along Figures 1 to 4 The workpiece 100 is flipped back and forth in the direction of the arc arrow shown, so that the workpiece 100 is blown at multiple angles to clean the dust adhering to it, and the dust suction component 8 sucks away the blown dust or other granular foreign matter to ensure the cleanliness of the dust removal bin. After the cleaning is completed, the controller controls the flip mechanism 5, the air blowing component 7 and the dust suction component 8 to close; the first shell component 1 rises with the lifting mechanism 3 and leaves the second shell component 2, and the cylinder 91 of the clamping mechanism 9 extends to make the clamping member 92 away from the first workpiece 101. If necessary, the clamping member 92 is rotated to make it away from the unloading path of the first workpiece 101, the second workpiece 102 and the tooling plate 103, and the first workpiece 101, the second workpiece 102 and the tooling plate 103 leave the storage table.
