[0003] During the coating process, the coating device needs to spray multiple products simultaneously. After the coating is completed, the products need to be taken out simultaneously. Since the products are not fixedly connected to the rack in the coating device, the products are likely to fall during the taking-out process, resulting in defective products. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a vacuum coating device, which solves the technical problem that the products are likely to fall during the process of taking out the products after coating multiple products simultaneously.

[0005] To achieve the above object, the utility model provides a vacuum coating device, which includes a box body, a rack and a lifting structure;

[0006] A rack is arranged in the box body. The rack includes a plurality of support plates and a plurality of connecting rods. The connecting rods penetrate through the support plates and are fixedly connected to the support plates. The connecting rods are of a hollow structure, and two of the plurality of connecting rods are internally provided with internal threads;

[0007] The lifting structure includes a motor, a connecting rod, a first lead screw and a second lead screw. The motor is fixedly arranged in the box body. The motor is in transmission connection with the connecting rod. Two ends of the connecting rod are respectively in transmission connection with the first lead screw and the second lead screw.

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0022] like Figure 1 - Figure 2As shown in the figure, the utility model discloses a vacuum coating device, which comprises a box body 1, a frame body 2 and a lifting structure 3. The interior of the box body 1 is a coating working area. A detachable cover plate 5 is fixedly connected to the top of the box body 1, and the connection between the cover plate 5 and the box body 1 is sealed.

[0023] The frame body 2 is used for placing the products to be coated. The frame body 2 includes a plurality of support plates 21 and a plurality of connecting rods 22. Taking Figure 1 、 Figure 2 as an example, in this embodiment, the number of the support plates 21 is three, and these three support plates 21 are arranged at intervals in sequence from bottom to top; the number of the connecting rods 22 is four, and these four connecting rods 22 respectively pass through the four corners of the support plates 21, and the connecting rods 22 are welded to the support plates 21. The interior of the connecting rods 22 is a cavity, and internal threads are provided in the cavity, that is, the connecting rods 22 are internal threaded tubes.

[0024] The lifting structure 3 includes a motor 31, a connecting rod 32, a first lead screw 33, a second lead screw 34, a worm and worm gear reducer 35, a first right-angle reducer 36 and a second right-angle reducer 37. As Figure 2 shown, the motor 31 is fixedly arranged inside the box body 1. The motor 31 is in transmission connection with the connecting rod 32 through the worm and worm gear reducer 35, that is, the motor 31 can drive the connecting rod 32 to rotate through the worm and worm gear reducer 35. The left end of the connecting rod 32 is in transmission connection with the first lead screw 33 through the first right-angle reducer 36. The first lead screw 33 is vertically arranged, and the first lead screw 33 is arranged in one of the connecting rods 22 in a threaded connection manner; the right end of the connecting rod 32 is in transmission connection with the second lead screw 34 through the second right-angle reducer 37. The second lead screw 34 is vertically arranged, and the second lead screw 34 is arranged in another connecting rod 22 in a threaded connection manner. The first lead screw 33 and the second lead screw 34 are provided with the same-direction threads, and the rotation directions of the first lead screw 33 and the second lead screw 34 are the same.

[0025] In order to further ensure the stable lifting of the frame body 2, vertical guide rods 11 are fixedly arranged inside the box body 1. Please refer to Figure 2 , in this embodiment, the number of the guide rods 11 is two. At this time, the first lead screw 33, the second lead screw 34 and the two guide rods 11 are respectively arranged in the four connecting rods 22. Since the guide rods 11 only play a guiding role, the outer walls of the guide rods 11 should be smooth. Obviously, the inner cavities of the connecting rods 22 corresponding to the two guide rods 11 can also be smooth.

[0026] As Figure 1 、 Figure 2As shown, a plurality of atomizing devices 4 are fixedly arranged on the inner side wall of the box body 1. The atomizing devices 4 are used to spray the coating agent. In order to make the spraying of the coating agent more uniform, a plurality of atomizing devices 4 can be arranged above the side of each support plate 21. The number and spacing of the atomizing devices 4 can be adjusted according to the actual situation. It should be noted that the atomizing devices 4 cannot extend directly above the support plate 21 to prevent the atomizing devices 4 from jamming the support plate 21 and affecting the up and down movement of the frame body 2.

[0027] During use, first place the products to be coated evenly on the support plate 21, and then start the motor 31. The motor 31 drives the connecting rod 32 to rotate, causing the first lead screw 33 and the second lead screw 34 to rotate in the same direction. The first lead screw 33 and the second lead screw 34 simultaneously drive the connecting rod 22 to move downward, thereby causing the frame body 2 to move downward. When it moves to an appropriate position, the motor 31 stops working, and the cover plate 5 is covered. The atomizing device 4 is started to start coating. After the coating is completed, start the motor 31 again to reverse the motor 31, so that the frame body 2 moves upward. Since the upward movement principle is similar to the downward movement principle, it will not be elaborated here. When the frame body 2 moves upward to an appropriate height, stop the motor 31.

[0028] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
