Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum coating machines, in particular to a target gate structure with double push rods. Background Art
[0002] With the advancement of science and technology, vacuum coating technology has been widely used in fields such as semiconductors, optics, and materials science. As the key equipment for implementing this technology, the performance of the coating machine directly affects the coating quality and efficiency. Existing vacuum coating machines have certain limitations in the design of the target gate's flip mechanism.
[0003] Currently, the target door flipping mechanism of vacuum coating machines mostly uses a single-rod drive. Whether driven by hydraulics or electric cylinders, some common problems exist. First, due to the height of the vertical target door, a large space is required when it needs to be flipped to the horizontal position. Second, the target door's fixed hinge needs to be installed at a high position on the equipment, which not only increases the height of the equipment, but also places higher requirements on the hinge's structural design and processing, thereby increasing costs.
[0004] Furthermore, the existing target gate flipping mechanism suffers from poor stability and is prone to shaking during the flipping process due to the limitations of a single-rod drive. This can affect the coating process and reduce coating quality. Furthermore, the single-rod drive can wear and fatigue over time, resulting in reduced drive efficiency and increased maintenance costs and downtime. Utility Model Content
[0005] The purpose of the utility model is to solve the shortcomings of the prior art, such as the height of the vertical target gate is relatively high and a large space is required when it needs to be flipped to a horizontal position, and a target gate structure with double push rods is proposed.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A double-push rod target gate structure is designed, comprising a base and a fixed base distributed at intervals, a rotating arm rotatably connected above the fixed base, and a first pushing component driving the rotating arm to rotate is provided on the base;
[0008] A target gate is rotatably connected above the rotating arm, and a second pushing component for driving the target gate to rotate is also installed in the middle of the inner side of the rotating arm.
[0009] Furthermore, the first pushing component is an electric push rod;
[0010] An avoidance groove is provided on the end surface of the base, and the tail end of the electric push rod is pin-connected and rotated in the avoidance groove.
[0011] Furthermore, a hinge seat is fixedly mounted on the end surface of the target gate facing the base, and the telescopic end of the electric push rod is rotatably connected to the hinge seat.
[0012] Furthermore, the second pushing assembly includes a mounting seat that is rotated on the inner side of the rotating arm through a first pin shaft, and a worm gear push rod is fixed on the mounting seat, and the rod end of the worm gear push rod rotates with the bottom pin of the target gate.
[0013] Furthermore, the target gate includes two bent edges, which are symmetrically distributed on both sides of the rotating arm. A connecting edge is fixedly connected between the two ends of the two bent edges, and several reinforcing plates are fixed between the inner sides of the two bent edges.
[0014] Furthermore, the fixing seat and the rotating arm, as well as the rotating arm and the target gate are rotationally connected via a second pin shaft.
[0015] The utility model proposes a double-push rod target door structure, which has the following beneficial effects: in the double-push rod target door flipping structure of the utility model, the target door is connected to the rotating arm through the second pin shaft, and the rotating arm is connected to the fixed seat through the second pin shaft. The target door, the rotating arm and the base can be linked together, and the target door and the base can be stopped at any position within the range of degrees through the two-stage linkage of the electric push rod and the worm gear push rod. The double-push rod structure pushes the target door from the horizontal open state to the vertical closed state in two stages to realize the opening and closing of the target door. The working space required for flipping is relatively small, and the flipping is flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0023] Reference Figure 1-5 This is an embodiment of the utility model, which discloses a double-push rod target gate structure. The flip structure includes a base 1 and a fixed base 2 that are spaced apart. The base 1 and the fixed base 2 are fixed horizontally at the bottom, and the base 1 and the fixed base 2 are directly fixed to the ground. A rotating arm 3 is rotatably connected above the fixed base 2. A first pushing component 4 is provided on the base 1 to drive the rotating arm 3 to rotate.
[0024] A target gate 5 is rotatably connected above the rotating arm 3 , and a second pushing component 6 is also installed in the middle of the inner side of the rotating arm 3 to drive the target gate 5 to rotate.
[0025] In some embodiments, the first pushing component 4 in the present invention is an electric push rod;
[0026] An avoidance groove 11 is provided on the end face of the base 1, and the tail end of the electric push rod is pinned and rotated in the avoidance groove 11. The specific design of the avoidance groove 11 is used to achieve avoidance of the electric push rod at different rotation angles, while saving installation space. Preferably, the avoidance groove 11 described in this embodiment is set as a straight groove. In addition, in this embodiment, a step is also provided on the side of the base 1, and the height of the step is lower than the height of the base 1. The purpose of this design is to avoid the rotation position of the rotating arm 3 when the above-mentioned rotating arm 3 is folded, so as to further optimize the installation space.
[0027] On the basis of the above embodiment, in the present invention, a hinge seat 51 is fixedly mounted on the end surface of the target gate 5 facing the base 1 , and the telescopic end of the electric push rod is rotatably connected to the hinge seat 51 .
[0028] In a further embodiment, the second pushing assembly 6 in this embodiment includes a mounting seat 62 on the inner side of the rotating arm 3 rotated by a first pin shaft 61, and a worm gear pusher 63 is fixed on the mounting seat 62. The worm gear pusher 63 is a worm gear type electric pusher, which uses its retractable and self-locking structural characteristics to achieve stable control and support of the target gate 5, and the rod end of the worm gear pusher 63 rotates with the bottom pin of the target gate 5.
[0029] It should be noted that, in this embodiment, the target gate 5 includes two bent edges 52, the bent edges 52 are L-shaped, and a number of mounting holes are opened on the upper bent surface thereof. The two bent edges 52 are symmetrically distributed on both sides of the rotating arm 3, and a connecting edge 53 is fixedly connected between the two ends of the two bent edges 52, and a number of reinforcing plates 54 are also fixed between the inner sides of the two bent edges 52.
[0030] Preferably, in this embodiment, the fixing seat 2 and the rotating arm 3 , as well as the rotating arm 3 and the target gate 5 are rotationally connected via a second pin shaft 7 .
[0031] Specifically, the target gate 5 of the present invention is connected to the rotating arm 3 through the second pin shaft 7, and the rotating arm 3 is connected to the fixed base 2 through the second pin shaft 7. The target gate 5, the rotating arm 3 and the base 1 can be linked together, and the target gate 5 can be stopped at any position within a 90-degree range between the base 1 through the two-stage linkage of the electric push rod and the worm gear push rod 63.
[0032] like Figure 3-5 As shown, the flip structure flips from the horizontal state of door opening to the mid-open state, and then enters the vertical state of door closing. During specific operation, when the target door 5 is in the horizontal state of door opening, when the target door 5 needs to be closed, the electric push rod is first extended by electrical control, and the electric push rod drives the rotating arm 3 to rotate, pushing the target door 5 to a certain angle, and then the worm gear push rod 63 is electrically controlled, and the push tube of the worm gear push rod 63 is retracted to a certain angle, controlling the target door 5 to rotate to a certain angle. Thereafter, the electric push rod further moves to push the rotating arm 3 to rotate until the target door 5 is controlled to rotate to the vertical state and hit the box body. Conversely, when the door is to be opened, the operation is performed in the opposite order of closing the door.
[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
