Description

Technical Field

[0001] The present application relates to the field of laser marking machines, and particularly to a lifting mechanism for a laser marking head. Background Art

[0002] Desktop laser marking machines are devices widely used for permanent marking on the surfaces of various materials. They usually use the up-and-down movement of the marking head to mark objects of different thicknesses. In this process, the lifting mechanism plays a key role. The lifting mechanism generally mainly includes a slider and pulleys. The slider moves up and down in the guiding groove of the marking machine through four pulleys on both sides, thereby driving the laser marking head to move up and down.

[0003] However, there are certain problems with the current lifting mechanisms on the market: due to the certain gap between the slider and the guiding groove, the marking head is prone to shaking during movement, resulting in inaccurate marking. This problem has become increasingly prominent with the increasing requirements for marking accuracy.

[0004] In order to improve the marking accuracy, it is necessary to optimize the design of the lifting mechanism. Specifically, it is necessary to design a lifting mechanism that can reduce the gap between the slider and the guiding groove, reduce the shaking amplitude, and improve stability. Utility Model Content

[0005] In order to solve the problem that the poor stability of the lifting mechanism affects the processing accuracy of the laser marking machine, the present application provides a lifting mechanism for a laser marking head.

[0006] The lifting mechanism for a laser marking head provided by the present application adopts the following technical solutions:

[0007] A lifting mechanism for a laser marking head includes a lifting slider and two groups of pulleys. The lifting slider includes a slider main body, an adjusting block, and an adjusting component disposed between the two. One group of pulleys is disposed on the slider main body, and the other group of pulleys is disposed on the adjusting block.

[0008] The adjusting component includes a holding member and an adjusting member. The adjusting block and the slider main body are connected to each other through the holding member, and the adjusting member is used to adjust the distance between the slider main body and the adjusting block.

[0009] By adopting the above technical solutions, it is allowed to precisely adjust the distance between the slider main body and the adjusting block, thereby optimizing the stability and accuracy of the entire slider. Since the stability and accuracy of the slider during movement directly affect the movement trajectory of the marking head, this technical solution is expected to significantly improve the marking accuracy.

[0010] Preferably, the holding member is arranged as a guide post, and the guide post is fixedly connected to the slider body; a guide hole that is inserted and matched with the guide post is arranged on the adjusting block; the adjusting member is arranged as a setscrew, and an adjusting hole that is threadedly matched with the setscrew is formed on the adjusting block; the end of the setscrew abuts against the side wall of the slider body.

[0011] By adopting the above technical solution, the cooperation of the guide post and the guide hole can provide stable guidance for the adjusting block, enabling it to move along a predetermined trajectory during adjustment and ensuring the accuracy of adjustment. At the same time, by rotating the setscrew, the distance between the slider body and the adjusting block can be finely adjusted, and this fine adjustment function is crucial for achieving high-precision marking.

[0012] Preferably, a first elastic tensioning member is further arranged at the end of the setscrew, and both ends of the first elastic tensioning member abut against the setscrew and the slider body respectively.

[0013] By adopting the above technical solution, the first elastic tensioning member can not only provide a certain elastic force to help stabilize the relative position between the slider body and the adjusting block, reduce the shaking during movement, but also absorb external impact forces to a certain extent, thereby further improving the stability and accuracy of marking.

[0014] Preferably, the first elastic tensioning member includes a first spring and a top plate, and there are two top plates which are respectively located at both ends of the first spring.

[0015] By adopting the above technical solution, the setscrew contacts the top plate, which is convenient for rotating the setscrew to adjust the distance between the adjusting block and the slider body. The functions of tensioning and buffering can be more effectively realized, providing strong support for the stable movement of the slider.

[0016] Preferably, the adjusting assembly further includes a holding post, and the holding post is fixedly connected to the slider body; a holding hole is formed on the adjusting block, the holding post extends into the holding hole, and a second spring is further sleeved on the holding post, and both ends of the second spring abut against the slider body and the adjusting block respectively and are in a compressed state.

[0017] By adopting the above technical solution, the additional holding post and the second spring provide additional stability for the adjusting block. The second spring is in a compressed state and can continuously apply a force in the direction away from the slider body to the adjusting block, thereby further reducing the shaking of the slider during movement and being beneficial to achieving higher-precision marking.

[0018] Preferably, the adjusting member is arranged as an adjusting screw, and the adjusting screw is rotatably connected to the slider body; an adjusting hole that is threadedly matched with the setscrew is formed on the adjusting block.

[0019] By adopting the above technical solution, the adjusting part is selected as an adjusting screw, which is not only convenient for adjustment in actual operation, but also can more precisely control the distance between the slider main body and the adjusting block, which is of great significance for improving the accuracy of the entire marking system.

[0020] Preferably, the adjusting hole penetrates through the adjusting block.

[0021] By adopting the above technical solution, it is convenient to perform adjustment operations from the side of the adjusting block facing away from the slider main body, improving the convenience of use.

[0022] Preferably, the adjusting assembly further includes a second elastic tensioning member disposed between the adjusting block and the slider main body. Both ends of the second elastic tensioning member are respectively connected to the adjusting block and the slider main body, and the elastic tensioning member is in a compressed state.

[0023] By adopting the above technical solution, the first elastic tensioning member is in a compressed state, which can continuously apply a force in a direction away from the slider main body to the adjusting block, thereby further reducing the shaking of the slider during movement, which is beneficial to achieving higher-precision marking.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By providing the slider main body, the adjusting block and the adjusting assembly, fine adjustment of the slider spacing can be achieved, thereby significantly improving the marking accuracy; the adjusting part can be selected as a set screw and an adjusting screw, with a simple, diverse and efficient structure.

[0026] 2. Structures such as the elastic tensioning member and the retaining post are added, effectively enhancing the stability of the slider, reducing the shaking during movement, and further improving the stability and accuracy of marking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] Example 1

[0036] This embodiment discloses a lifting mechanism for a laser marking head. Figure 1 , including a lifting slider 1 and two sets of pulleys 2, the lifting slider 1 includes a slider body 11, an adjustment block 12 and an adjustment component 13 arranged therebetween. One set of pulleys 2 is arranged on the slider body 11, and the other set of pulleys 2 is arranged on the adjustment block 12, so as to provide stable sliding support during the marking process.

[0037] Reference Figure 2 and Figure 3 The adjusting assembly 13 is the core part of the mechanism, and includes a retaining member 132 and an adjusting member 131. In this embodiment, the retaining member 132 is in the form of a guide column, which is fixedly connected to the slider body 11 to provide a stable guide for the adjusting block 12. The adjusting block 12 is processed with a guide hole 121 that cooperates with the guide column to ensure that the adjusting block 12 can move smoothly along the guide column.

[0038] The number of guide posts can be designed according to actual needs, and at least two are arranged in parallel to ensure the stable movement of the adjustment block 12. At the same time, the number of guide holes 121 on the adjustment block 12 should also match the number of guide posts.

[0039] The adjusting member 131 is used to adjust the distance between the slider body 11 and the adjusting block 12, thereby controlling the lifting height of the marking head. In this embodiment, the adjusting member 131 is a top screw, which is installed in the adjusting hole 122 provided on the adjusting block 12 through threaded engagement. By rotating the top screw, the relative position of the top screw and the side wall of the slider body 11 can be changed, thereby adjusting the distance between the slider body 11 and the adjusting block 12.

[0040] The implementation principle of Example 1 is: by rotating the top screw, the adjustment block 12 moves along the guide column, thereby changing the distance between the slider body 11 and the adjustment block 12. As a result, the pulley 2 can be closely abutted against the side wall of the guide groove, thereby reducing the shaking of the lifting mechanism during movement, ensuring the stability of the marking head, and further improving the marking accuracy.

[0041] Example 2

[0042] Reference Figure 4 , the difference between this embodiment and Embodiment 1 lies in the specific structure of the adjustment component 13. In this embodiment, in order to further enhance the stability and adjustment accuracy of the mechanism, a first elastic tensioning member 14 is added to the end of the setscrew. The first elastic tensioning member 14 is composed of a first spring 141 and a top plate 142. There are two top plates 142, which are respectively located at both ends of the first spring 141. When the setscrew is rotated to adjust the spacing, the first spring 141 is in a compressed state, thereby providing a certain tensioning force for the adjustment block 12, ensuring the stability of the adjustment block 12, helping to reduce the shaking of the adjustment block 12, and improving the marking accuracy.

[0043] Example 3

[0044] Reference Figure 5 , on the basis of Embodiment 1 or Embodiment 2, this embodiment provides an enhanced stability solution. In addition to including the guide post and the setscrew, the adjustment component 13 is also provided with a retaining post 133 and a second spring 134. The retaining post 133 is fixedly connected to the slider body 11, and a corresponding retaining hole is opened on the adjustment block 12. The retaining post 133 extends into the retaining hole. At the same time, a second spring 134 is sleeved on the retaining post 133, and both ends of the spring are respectively abutted against the slider body 11 and the adjustment block 12 and are in a compressed state. Through the elastic force of the second spring 134, the gap can be further reduced, the shaking of the slider can be inhibited, and the stability and accuracy of marking can be improved.

[0045] Example 4

[0046] This embodiment shows another selection scheme of the adjustment member 131. The difference from Embodiment 1 is that, with reference to Figure 6 , the adjustment member 131 uses an adjustment screw instead of a setscrew. The adjustment screw is rotatably connected to the slider body 11, and a corresponding adjustment hole 122 for threaded cooperation is machined on the adjustment block 12. By rotating the adjustment screw, the adjustment of the spacing between the slider body 11 and the adjustment block 12 can also be achieved. In addition, in order to enhance the stability, a second elastic tensioning member 15 can also be added between the adjustment block 12 and the slider body 11. Both ends of the second elastic tensioning member 15 are respectively connected to the adjustment block 12 and the slider body 11, and the second elastic tensioning member 15 is in a compressed state.

[0047] In summary, the lifting mechanism of the laser marking head provided by this application solves the problem of marking accuracy caused by the shaking of the slider in the traditional mechanism through a clever structural design. Each embodiment shows different adjustment and stability solutions, which can be flexibly selected according to the actual application scenario to meet the needs of different users.

[0048] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
