[0030] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

The first feature being "below", "below" and "below" the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0033] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0034] like Figures 1-10As shown, the present invention provides a moving device for moving workpieces, such as moving workpieces with cylindrical structures. In this embodiment, the workpiece is a feed source 20 for an antenna, but it should not be understood to be limited to this. The moving device includes a platform 10, a moving assembly 1 and two positioning assemblies 2. The moving assembly 1 is used to move the workpiece, and the moving assembly 1 includes a driving member 11, a connecting rod 14, two swing arms 13 and two positioning seats 15. The driving member 11 is used to drive one of the swing arms 13 to swing, and the two swing arms 13 are arranged in parallel and are both rotatably connected to the platform 10. The two ends of the connecting rod 14 are respectively hinged to the two swing arms 13, and the connecting rod 14 is parallel to the platform 10. The two positioning seats 15 are respectively connected to the two swing arms 13, and the two positioning assemblies 2 are respectively installed on the two workpieces. The two positioning seats 15 are positioned and matched with the two positioning assemblies 2. When the swing arm 13 swings, the two workpieces move relative to the platform 10 at the same time. The connecting rod 14 of the moving assembly 1 and the two swing arms 13 form a parallelogram structure, so that the two positioning seats 15 can be lifted and lowered and translated relative to the platform 10 as the two swing arms 13 swing. Through the cooperation between the positioning assembly 2 and the positioning seats 15, the two workpieces can be lifted and lowered and translated relative to the platform 10 at the same time with the same motion trajectory, realizing switching, reducing the number of operating steps, reducing time consumption, and maintaining a good posture during the moving process.

[0035] Furthermore, if Figure 3-Figure 6 As shown, the positioning assembly 2 includes a flange 21, which is fixedly connected to the workpiece. A support rod 22 is fixedly provided on the flange 21, extending in a direction away from the workpiece, and a positioning groove 221 is provided on the support rod 22. The positioning seat 15 is fixedly provided with an extension arm 151, and the extension arm 151 is provided with a positioning protrusion 152, which is positioned and matched with the positioning groove 221. The swinging of the swing arm 13 drives the positioning seat 15 to move, so that the positioning protrusion 152 cooperates with the positioning groove 221, and drives the positioning assembly 2 and the workpiece to move synchronously. During the entire swinging process of the swing arm 13, both workpieces move along the movement path of the positioning seat 15 to achieve the movement and position switching of the workpieces. A reinforcing rib 153 is also provided between the extension arm 151 and the positioning seat 15. The two ends of the reinforcing rib 153 are respectively fixedly connected to the positioning seat 15 and the extension arm 151 to increase the rigidity and structural strength of the extension arm 151, providing reliable support for the process of moving the workpiece. To improve workpiece stability during transport, this embodiment includes three support rods 22, arranged in a herringbone pattern on flange 21. Each of the three support rods 22 is equipped with a positioning slot 221. Three extension arms 151 are provided, each equipped with a positioning protrusion 152, each corresponding one-to-one with the three positioning slots 221. Thus, the three positioning protrusions 152 and the three positioning slots 221 cooperate to provide three-point support for the workpiece, improving its stability during transport.

[0036] Optionally, in order to achieve smooth engagement and disengagement between the positioning protrusion 152 and the positioning groove 221 during the moving process, the cross-sectional shape of the positioning protrusion 152 along the length direction perpendicular to the extension arm 151 is triangular. Correspondingly, the cross-sectional shape of the positioning groove 221 along the length direction perpendicular to the support rod 22 is also set to be triangular. Taking the swing arm 13 swinging clockwise as an example, please refer to Figure 7-10 As shown, the swing arm 13 swings in the clockwise direction at the left extreme position, and the positioning protrusion 152 gradually approaches and enters the positioning groove 221. Figure 7 As the swing arm 13 continues to swing, the positioning protrusion 152 cooperates with the positioning groove 221, driving the workpiece to rise to a certain height and then fall, while moving to the right. Figure 8-Figure 9 After the workpiece falls, the platform 10 or other supporting members provide support for the workpiece, and the workpiece no longer moves with the positioning seat 15. At this time, as the swing arm 13 further swings, the positioning protrusion 152 gradually disengages from the positioning groove. For details, see Figure 10 When the swing arm 13 swings to the right limit position, the positioning protrusion 152 completely disengages from the positioning groove 221, completing the workpiece movement to the right. Similarly, when the workpiece needs to be moved to the left, the swing arm 13 is at the right limit position. The swing arm 13 swings counterclockwise to the left limit position to complete the movement. The specific process is the same or similar to the process of swinging the swing arm 13 clockwise at the left limit position, so it will not be repeated here.

[0037] For details, please refer to Figure 4 As shown, the swing arm 13 includes two parallel sub-swing rods, both of which are hinged to the positioning seat 15. The lower ends of the two sub-swing rods are hinged to the support 12, and the support 12 is fixedly connected to the platform 10. The two sub-swing rods are hinged to the positioning seat 15, that is, there are two connection points between the positioning seat 15 and the swing arm 13. Therefore, the positioning seat 15 will not swing or shake relative to the swing arm 13 during the process of moving the workpiece, and the movement posture of the positioning seat 15 during the movement is more optimal. Both ends of the connecting rod 14 are provided with a receiving groove 141. The two swing arms 13 pass through the two receiving grooves 141 and are hinged to the connecting rod 14. By providing the receiving grooves 141 at both ends of the connecting rod 14, the space occupied by the moving assembly 1 is reduced, which is conducive to improving the compactness of the structure. The driving member 11 includes a mounting seat 111 and an electric push rod 112. The mounting seat 111 is fixedly connected to the platform 10, and the electric push rod 112 is mounted on the mounting seat 111. The output shaft of the electric push rod 112 is hinged to one of the swing arms 13, and the swing arm 13 swings by extending and retracting the electric push rod 112. The output shaft of the electric push rod 112 forms an angle with the swing arm 13 to avoid dead spots that could cause the mechanism to become stuck. In other embodiments, a combination of a rotary motor and a reducer can also be used to drive the swing arm 13, but the specific structure is not described in detail here.

[0038] Furthermore, if Figure 1-Figure 2 As shown, a track 30 and two brackets 40 are installed on the platform 10. The two brackets 40 are located on both sides of the track 30. The distance between the two brackets 40 and the track 30 is equal. One workpiece is located on the track 30, and the other workpiece is located on one of the two brackets 40. When moving the workpiece, please refer to Figure 1 As shown, at this time, the workpiece on the left is located on the bracket 40 on the left side of the track 30, the workpiece on the right is located on the track 30, and the moving assembly 1 is at the left limit position. When the swing arm 13 swings clockwise until the moving assembly 1 is at the right limit position, the workpiece on the left is located on the track 30, and the workpiece on the right is located on the bracket 40 on the right side of the track 30. For details, refer to Figure 2 As shown, the workpiece movement and switching are completed.

[0039] Optionally, the positioning assembly 2 further includes a limit plate 23, which is fixedly connected to the workpiece. In this embodiment, the limit plate 23 is fixedly connected to the flange 21 or the limit plate 23 serves as a part of the flange 21. The limit plate 23 is used to limit the workpiece from rolling on the bracket 40. Specifically, the limit plate 23 is provided with a planar structure, and the bracket 40 is provided with a corresponding planar structure that cooperates with it. When the workpiece is placed on the bracket 40, the planar structure on the limit plate 23 cooperates with the planar structure of the bracket 40 to prevent the workpiece from rolling on the bracket 40, thereby ensuring that the positioning protrusion 152 and the positioning groove 221 can smoothly engage or disengage.

[0040] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
