[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] like Figures 1-10As shown, this utility model provides a moving device for moving workpieces, such as cylindrical workpieces. In this embodiment, the workpiece is the feed 20 of an antenna, but this should not be construed as a limitation. 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 includes a drive member 11, a connecting rod 14, two swing arms 13, and two positioning seats 15. The drive member 11 drives one of the swing arms 13 to swing. The two swing arms 13 are arranged in parallel and 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 mounted on the two workpieces. The two positioning seats 15 are positioned and engaged with the two positioning assemblies 2. When the swing arm 13 swings, the two workpieces move simultaneously relative to the platform 10. The connecting rod 14 and the two swing arms 13 of the transfer component 1 form a parallelogram structure, so that the two positioning seats 15 can move up and down and translate relative to the platform 10 as the two swing arms 13 swing. Through the cooperation of the positioning component 2 and the positioning seats 15, the two workpieces can move up and down and translate relative to the platform 10 at the same time with the same motion trajectory, realize switching, reduce operation steps, reduce time consumption, and maintain good posture during the transfer process.

[0035] Furthermore, such as Figures 3-6 As shown, the positioning assembly 2 includes a flange 21, which is fixedly connected to the workpiece. A support rod 22 is fixedly mounted on the flange 21, extending away from the workpiece, and a positioning groove 221 is provided on the support rod 22. An extension arm 151 is fixedly mounted on the positioning seat 15, and a positioning protrusion 152 is provided on the extension arm 151, which is positioned and engaged with the positioning groove 221. The swing of the swing arm 13 drives the positioning seat 15 to move, thereby engaging the positioning protrusion 152 with the positioning groove 221 and driving the positioning assembly 2 and the workpiece to move synchronously. During the entire swing of the swing arm 13, both workpieces move along the moving path of the positioning seat 15 to realize the transfer and position switching of the workpieces. A reinforcing rib 153 is also provided between the extension arm 151 and the positioning seat 15, with both ends of the reinforcing rib 153 fixedly connected to the positioning seat 15 and the extension arm 151 respectively, to improve the rigidity and structural strength of the extension arm 151 and provide reliable support for the process of transferring the workpiece. To improve stability during workpiece handling, this embodiment uses three support rods 22 arranged in a triangular pattern on the flange 21. Each of the three support rods 22 has a positioning groove 221, and three extension arms 151 are also provided, each with a positioning protrusion 152. The three positioning protrusions 152 correspond one-to-one with the three positioning grooves 221. Thus, the three positioning protrusions 152 and the three positioning grooves 221 work together to provide three-point support for the workpiece, improving stability during workpiece handling.

[0036] Optionally, to ensure smooth engagement and disengagement between the positioning protrusion 152 and the positioning groove 221 during transport, 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 triangular. For example, consider the clockwise swing of the swing arm 13. Figures 7-10 As shown, the swing arm 13 swings clockwise at its left extreme position. At this time, the positioning protrusion 152 gradually approaches and enters the positioning groove 221. See the specific reference. Figure 7 As shown, as the swing arm 13 continues to swing, the positioning protrusion 152 engages with the positioning groove 221, causing the workpiece to rise to a certain height and then fall, while simultaneously moving to the right. See the attached diagram for details. Figures 8-9 As shown. After the workpiece falls, the platform 10 or other support components provide support for the workpiece, and the workpiece no longer moves with the positioning seat 15. At this time, as the swing arm 13 swings further, the positioning protrusion 152 gradually disengages from the positioning groove, as shown in the figure. Figure 10 As shown. When the swing arm 13 swings to the right limit position, the positioning protrusion 152 completely disengages from the positioning groove 221, completing the rightward transfer of the workpiece. Similarly, when the workpiece needs to be transferred to the left, the swing arm 13 is at the right limit position. Swinging the swing arm 13 counterclockwise to the left limit position completes the transfer. The specific process is the same as or similar to the process of the swing arm 13 swinging clockwise at the left limit position, so it will not be described again.

[0037] Specifically, please refer to Figure 4 As shown, the swing arm 13 includes two parallel sub-swing arms, both of which are hinged to the positioning seat 15. The lower ends of the two sub-swing arms are hinged to the support 12, which is fixedly connected to the platform 10. The hinged connection between the two sub-swing arms and the positioning seat 15 means there are two connection points between the positioning seat 15 and the swing arm 13, preventing the positioning seat 15 from swinging or wobbling relative to the swing arm 13 during workpiece movement, resulting in a better movement posture for the positioning seat 15 during the movement. Both ends of the connecting rod 14 are provided with receiving grooves 141, through which the two swing arms 13 pass and are hinged to the connecting rod 14. By providing receiving grooves 141 at both ends of the connecting rod 14, the space occupied by the moving assembly 1 is reduced, which helps to improve the compactness of the structure. The driving component 11 includes a mounting base 111 and an electric actuator 112. The mounting base 111 is fixedly connected to the platform 10, and the electric actuator 112 is mounted on the mounting base 111. The output shaft of the electric actuator 112 is hinged to one of the swing arms 13, and the swing arm 13 is oscillating by the extension and retraction of the electric actuator 112. The output shaft of the electric actuator 112 and the swing arm 13 form an angle to avoid dead points that could cause the mechanism to jam. In other embodiments, a combination of a rotary motor and a reducer can also be used to drive the swing arm 13 to swing; the specific structure will not be described in detail here.

[0038] Furthermore, such as Figures 1-2 As shown, a track 30 and two supports 40 are installed on platform 10. The two supports 40 are located on both sides of the track 30, and the distance between the two supports 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 supports 40. When moving the workpiece, please refer to... Figure 1 As shown, at this time, the workpiece on the left is located on the support 40 on the left side of the track 30, and the workpiece on the right is located on the track 30, with the transfer assembly 1 at its left extreme position. When the swing arm 13 swings clockwise until the transfer assembly 1 is at its right extreme position, the workpiece on the left is located on the track 30, and the workpiece on the right is located on the support 40 on the right side of the track 30. See the attached diagram for details. Figure 2 As shown, this completes the transfer and switching of the workpiece.

[0039] Optionally, the positioning component 2 further includes a limiting plate 23, which is fixedly connected to the workpiece. In this embodiment, the limiting plate 23 is fixedly connected to the flange 21, or the limiting plate 23 is part of the flange 21. The limiting plate 23 is used to restrict the workpiece from rolling on the bracket 40. Specifically, the limiting plate 23 is provided with a planar structure, and the bracket 40 is provided with a corresponding planar structure. When the workpiece is placed on the bracket 40, the planar structure on the limiting 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 this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
