Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

It will be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience in describing the present application and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

Further, in the description of the present application, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 5 together, a coating machine according to an embodiment of the present application will be described. The applicator includes a stage 20 for carrying a product to be sprayed, a rotation assembly 30 for driving the stage 20 to rotate, and a spray assembly 10 for performing a spraying operation on the product to be sprayed on the stage 20.

In this embodiment, the product to be sprayed is a three-dimensional structure, and has a plurality of surfaces to be sprayed, and the surfaces to be sprayed may be flat surfaces or curved surfaces. It will be appreciated that in the event of localised depressions or the like in the product to be sprayed, it is likely to be obscured by other surfaces during spraying, leading to a situation where the spray is not in place. If the mode that adopts manipulator 11 to remove is treated each of spraying product and is treated the spraying face and carry out the spraying, there are the problem that control is complicated, with high costs, and be unfavorable for batch production. The spraying machine provided by the embodiment has the advantages that the surfaces to be sprayed of the products to be sprayed are in contact with the spraying direction of the nozzle 12 at a plurality of angles in the form of the rotary object stage 20, so that the probability of incomplete spraying is reduced, and the spraying quality of the products is improved.

Specifically, the spray assembly 10 includes a spray nozzle 12 and has a spray footprint. Spray coverage area refers to the area that the nozzle 12 can spray. The rotation assembly 30 is used to rotate the object stage 20 so that the product to be sprayed on the object stage 20 rotates within the coverage area of the spray.

It should be noted that the nozzle 12 may be in a fixed position for spraying at a specific angle, or may be moved by a robot or other movable support structure to change the spraying angle during operation.

Preferably, the spray assembly 10 further includes a robot 11 having multiple degrees of freedom, and the nozzle 12 is disposed at an end of an arm of the robot 11. The manipulator 11 has multiple degrees of freedom and can adjust the spraying height and the spraying angle of the nozzle 12, thereby meeting the spraying requirements of different products to be sprayed and improving the applicability of the spraying machine. It will be appreciated that the spray coverage area in the case of the robot 11 is defined as the area that the spray nozzles 12 can spray under the control of the robot 11. In the case of the robot 11, the nozzle 12 can also have two different operating modes during the painting operation. One is relatively fixed, i.e. the robot 11 is stationary after adjusting the appropriate height and angle, and is in a relatively stationary state throughout the spraying process, with the spray nozzle 12 spraying at a particular angle. And the other is an adjustable state, the mechanical arm 11 moves under the automatic control during the spraying process, so that the spray nozzle 12 changes the spraying angle during the operation. For convenience of description, the present embodiment will be described by taking as an example the case where the nozzle 12 performs the spraying operation at a fixed position and at a specific angle.

The rotation assembly 30 rotates the object stage 20 to rotate the product to be sprayed on the object stage 20 within the spray coverage area. It should be noted that the stage 20 itself may or may not be located entirely or partially within the spray coverage area. Preferably, the stage 20 itself is positioned within the spray coverage area. Under the rotation of the objective table 20, the product to be sprayed rotates to continuously change the relative angle between the product to be sprayed and the nozzle 12, so that each surface to be sprayed of the product to be sprayed has an opportunity to face the nozzle 12 (without being shielded) to be sprayed, thereby improving the spraying quality of the finished product. In another aspect, compared with the spraying method in which the product to be sprayed is fixed and the spraying angle of the nozzle 12 is changed, the method has the advantages of lower equipment cost and more convenient operation and control.

Therefore, the spraying machine provided by the embodiment can improve the spraying quality of the product to be sprayed.

In this embodiment, the rotation assembly 30 rotates the stage 20, preferably by rotating the stage 20 (the stage 20 rotates along an axis that traverses the stage 20 itself). It will be appreciated that the same effect of improving the quality of the coating can be achieved when the stage 20 is rotated about an axis offset from the stage 20 itself. In this embodiment, the stage 20 is horizontally disposed and rotated on a horizontal plane, and the product to be sprayed is disposed above the stage 20. The motor is located below the object stage 20 and drives the object stage 20 to rotate through a toothed belt wheel.

In another embodiment of the present application, referring to fig. 2 or 3, the coating machine further comprises a moving assembly 50, wherein the moving assembly 50 is used for driving the object stage 20 to move linearly within the coating coverage area. It is not to be understood that the range of the spray coverage area encompasses the range of travel paths of the product to be sprayed. Some products to be sprayed need to move back and forth for spraying, and the operation requirement can be met by the additional arrangement of the moving assembly 50.

Preferably, the moving assembly 50 is a linear module to simplify the equipment manufacturing cost. In other embodiments, the moving assembly 50 may also be a screw structure, a slide structure, etc., as long as the linear movement of the stage 20 is realized.

In another embodiment of the present application, referring to fig. 4 or fig. 5, the object stage 20 is provided with a tray 40 for placing the product to be sprayed, and the tray 40 is detachably connected to the object stage 20. The addition of the material tray 40 can put the product to be sprayed into the material tray 40 at a place far away from the object stage 20, and then the material tray 40 is put on the object stage 20, so that the operation time of the object stage 20 is shortened, and the operation efficiency of the spraying machine is improved. On the other hand, different products to be sprayed can be adapted to by replacing different trays 40 without replacing the object stage 20, and the equipment cost of the spraying machine is reduced.

The objective table 20 and the material tray 40 are detachably connected and can be fixed by bolts, magnetic attraction, clamping, interference fit, and the like. The interference fit fixing refers to that the object stage 20 is provided with a cavity in interference fit with the material tray 40, and the material tray 40 is arranged in the cavity to realize fixing.

In the structure shown in fig. 5, the object stage 20 is horizontally placed, the object stage 20 is provided with a containing cavity for containing the material tray 40, the object stage 20 is provided with a rotatable or/and movable pressing bar 21, and the pressing bar is used for pressing the material tray 40 on the object stage 20. The switching between the retracted state and the pressed state is effected by a rotation or/and a displacement of the press bar 21. When the pressing strip 21 is in the avoiding state, the pressing strip 21 leaves the space above the material tray 40, and when the pressing strip 21 is in the pressing state, the pressing strip 21 turns or/and moves to the space above the material tray 40 to limit the upward movement of the material tray 40.

In another embodiment of the present application, referring to fig. 4 or fig. 5, the object stage 20 has a plurality of accommodating cavities formed on an upper surface thereof for accommodating the material trays 40, and the accommodating cavities are arranged in rows and columns. One accommodating chamber accommodates one tray 40 correspondingly. The plurality of accommodating cavities are arranged, so that the spraying machine can simultaneously spray the products to be sprayed on the plurality of charging trays 40, and mass production is realized. The arrangement of the rows and columns of the accommodating cavities can increase the number of the trays 40 that can be accommodated by the stage 20, and facilitate automatic feeding and discharging operations.

In another embodiment of the present application, the walls of the accommodating chamber can limit the movement of the tray 40 therein in the horizontal direction. In the structure shown in fig. 5, the tray 40 is square, and the accommodating cavity is matched with the tray 40 to fix the tray 40 and prevent the tray 40 from loosening during the rotation of the stage 20. It can be understood that, in the case where the tray 40 is square, the accommodating chamber only needs to have side walls abutting against the tray 40 at the front, rear, left and right sides, and it is not necessary that the walls of the accommodating chamber all abut against the tray 40.

In another embodiment, referring to fig. 5, the object stage 20 is provided with a material taking groove 201 at two opposite sides of each accommodating cavity, which is communicated with the accommodating cavity. The material taking groove 201 is arranged so that a person or a machine can conveniently extend into the material taking groove 201 to take and place the material tray 40.

In another embodiment of the present application, the applicator further comprises a shield 60 for the mask stage 20. It is not to be understood that the nozzle 12 is located within the shield 60 and the shield 60 confines the coating material sprayed by the nozzle 12 to the interior space of the shield 60 to prevent or reduce contamination and to ensure the health of the operator.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
