Description

Technical Field

[0001] This utility model relates to the field of guide rail docking technology, specifically to a high-precision automatic docking guide rail unit. Background Technology

[0002] In fields such as industrial automation, precision manufacturing, aerospace, and logistics warehousing, automated docking technology for equipment or vehicles is a core component for achieving efficient material handling, equipment assembly, and system integration. Traditional mechanically guided docking methods suffer from low positioning accuracy and are prone to excessive collisions during the docking process, failing to meet the high precision and reliability requirements of modern industry. Therefore, a novel automated docking guide rail unit is needed to optimize these issues. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a high-precision automatic docking guide rail unit.

[0004] The technical solution of this utility model is: a high-precision automatic docking guide rail unit, including a docking socket disposed on a first guide rail and a docking plug disposed on a second guide rail. The outer ends of the docking socket have first beveled surfaces on both sides. Magnetic adjustment blocks are provided on each of the first beveled surfaces. The magnetic adjustment blocks are connected to the first beveled surfaces via telescopic rods. A first airbag is provided on the first beveled surface that contacts the magnetic adjustment block. The magnetic adjustment block has a cavity, and positive and negative magnetic plates are rotatably disposed in the cavity. A second airbag for adjusting the rotation of the positive and negative magnetic plates to switch the positive and negative poles is provided in the cavity. The first airbags of the two magnetic adjustment blocks are respectively connected to the second airbag in the magnetic adjustment block on the opposite side via pipes. The outer ends of the docking plug have second beveled surfaces on both sides. Magnetic sheets that cooperate with the positive and negative magnetic plates are provided on the second beveled surfaces.

[0005] Furthermore, the middle part of the positive and negative magnetic plates is rotatably connected to the inner walls of both sides of the cavity via a rotating shaft, and the inner walls of both sides of the cavity are provided with limiting plates for limiting the rotation angle of the rotating shaft.

[0006] Note: By setting a limit plate, the rotation angle of the positive and negative magnetic plates can be prevented from being too large, which would affect the switching of the positive and negative magnetic surfaces. The limit plate can limit the rotation of the positive and negative magnetic plates to 180°, thereby further ensuring the realization of the docking guide rail unit function.

[0007] Furthermore, the magnetic force adjustment block has an opening on the side opposite to the magnetic sheet.

[0008] Note: Setting an opening can further reduce the influence of the magnetic force adjustment block material on the magnetic force, but it is not limited to this setting method. Materials with weak magnetic resistance can also be used as the shell material of the magnetic force adjustment block.

[0009] Furthermore, a spring is fitted onto the telescopic rod.

[0010] Note: By adding a spring, the self-recovery capability of the two magnetic adjustment blocks directly linked can be further improved, thus enabling the magnetic adjustment blocks to have a faster response speed when recovering.

[0011] Furthermore, the tangent angles of the first and second oblique cut surfaces are both 30 to 50°.

[0012] Note: Controlling the tangent angle within the above range can make the docking guide rail unit function more stable and avoid the difficulty in achieving the automatic guidance docking effect due to the tangent angle being too large or too small.

[0013] The beneficial effects of this utility model are:

[0014] The automatic docking guide rail unit of this utility model can improve the docking guidance range of the docking socket and the docking plug by using two sets of linked magnetic adjustment blocks. When the docking plug is biased to one side of the docking socket, the two sets of magnetic adjustment blocks can maintain magnetic repulsion on one side and magnetic attraction on the other side, thereby guiding the docking plug to be accurately inserted into the docking plug, thus completing the automatic guidance docking function.

[0021] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0022] Example 1: A high-precision automatic docking guide rail unit includes a docking socket 1 disposed on a first guide rail and a docking plug 2 disposed on a second guide rail. The outer ends of the docking socket 1 have first beveled surfaces 11 on both sides. Magnetic adjustment blocks 3 are provided on each of the first beveled surfaces 11. The magnetic adjustment blocks 3 are connected to the first beveled surfaces 11 via telescopic rods. Springs are sleeved on the telescopic rods. First airbags 4, which contact the magnetic adjustment blocks 3, are provided on the first beveled surfaces 11. The magnetic adjustment blocks 3 have cavities, and positive and negative magnetic plates 5 are rotatably disposed within the cavities. The cavities also contain facilities for adjusting the positive and negative magnetic plates 5. The second airbag 6, which switches between positive and negative poles, is rotated. Specifically, a push plate is provided on the rotating shaft 51. The second airbag 6 is semi-circular, with one end connected to the push plate and the other end connected to the magnetic adjustment block 3. The first airbags 4 of the two magnetic adjustment blocks 3 are respectively connected to the second airbags 6 in the opposite magnetic adjustment blocks 3 through pipes. The outer ends of the docking plug 2 have second oblique surfaces 21 on both sides. The second oblique surfaces 21 are provided with magnetic pieces 7 that cooperate with the positive and negative magnetic plates 5. The tangent angles of the first oblique surface 11 and the second oblique surface 21 are both 45°. The positive and negative magnetic plates 5 have one side as the positive pole and the other side as the negative pole. Figure 5 The structure shown is such that, in the initial state, the positive pole side of the positive and negative magnetic plates 5 faces outward, and the positive pole side of the magnetic sheet 7 faces outward, so that a magnetic repulsion force is formed between them.

[0023] The working principle of the aforementioned automatic docking guide rail unit is as follows: The docking socket 1 and the docking plug 2 are respectively installed on the first guide rail and the second guide rail. Then, the second guide rail with the docking plug 2 is inserted into the first guide rail with the docking socket 1. During insertion, if there is a docking misalignment between the docking plug 2 and the socket portion of the docking socket 1, the docking plug 2 will approach the magnetic adjustment block 3 on one side of the docking socket 1 and resist the magnetic repulsion force generated between the magnetic adjustment block 3 and the magnetic sheet 7 on the second oblique surface 21 of the docking socket 1. The closer the docking plug 2 is to the magnetic adjustment block 3, the greater the magnetic repulsion force will be.

[0024] At the same time, the magnetic adjustment block 3 is subjected to magnetic repulsion and continuously squeezes the first air bladder 4, causing the second air bladder 6 of the magnetic adjustment block 3 on the opposite side to expand due to the compression of the first air bladder 4. This causes the positive and negative magnetic plates 5 to rotate 180°, thereby changing the magnetic repulsion between the positive and negative magnetic plates 5 of the magnetic adjustment block 3 on the opposite side and the magnetic sheet 7 into a magnetic attraction, thereby attracting the docking plug 2 to shift to one side of the magnetic adjustment block 3 on the opposite side, thus correcting the offset problem of the docking plug 2.

[0025] Example 2: The difference between this example and Example 1 is that the middle part of the positive and negative magnetic plates 5 is rotatably connected to the inner walls of both sides of the cavity through a rotating shaft 51, and the inner walls of both sides of the cavity are provided with limiting plates 52 for limiting the rotation angle of the rotating shaft 51.

[0026] The working principle of the above-mentioned automatic docking guide rail unit is as follows: Based on the working principle of Embodiment 1, when the positive and negative magnetic plates 5 rotate, after the positive and negative magnetic plates 5 rotate 180°, the protrusion on the rotating shaft abuts against the limiting plate 52, thereby preventing the rotating shaft from continuing to rotate.

[0027] Example 3: The difference between this example and Example 1 is that the magnetic force adjustment block 3 has an opening on the side opposite to the magnetic sheet 7.

[0028] Example 4: The difference between this example and Example 1 is that the cutting angles of the first oblique cutting surface 11 and the second oblique cutting surface 21 are both 30°.

[0029] Example 5: The difference between this example and Example 1 is that the cutting angles of the first oblique cutting surface 11 and the second oblique cutting surface 21 are both 50°.
