Description

Technical Field

[0001] The utility model relates to the field of laser coding, in particular to a laser coding device for steps. Background Art

[0002] The step assembly operation requires the installation of the step spindle on a fixed tooling. In addition, laser coding is required at the designated position of the step to mark relevant information such as the step model, step number, manufacturer, and production date.

[0003] The current production process involves placing the steps on a workbench-mounted spindle fixture for assembly. Once the steps are assembled, they are transferred to the next process and placed on the coding fixture. Due to interference between the laser coding laser head's focal length and the step's secondary wheel, the product must be conveyed at a certain angle beneath the laser head for operation. This results in low production efficiency, and the repeated transfers are time-consuming and labor-intensive. Furthermore, the product must be transferred twice to different fixtures as required, often exposing the steps to quality issues. Utility Model Content

[0004] In order to improve the quality and efficiency of laser coding, the utility model provides a laser coding device for steps.

[0005] The utility model provides a laser coding device for steps, which adopts the following technical solutions:

[0006] A laser coding device for steps comprises a mounting seat arranged on the side of an assembly platform, a base arranged on the mounting seat, and a guide rail seat connected to the base; the guide rail seat is connected to the base via a rotating mechanism, and the rotating mechanism can rotate the guide rail seat out or move it above the assembly platform; a laser coding head is arranged on the guide rail seat, and the laser coding head can be moved and locked along the guide rail seat; the mounting seat can be moved and locked in the height direction of the assembly platform; and the base can be moved and locked in the longitudinal direction of the assembly platform.

[0018] As a preferred embodiment of the present invention, the rotating mechanism is a rotating motor, the rotating motor is fixed on the base, and the output shaft of the rotating motor is connected to the guide rail seat.

[0019] The above technical solution utilizes a rotary motor for the rotation mechanism, which is fixed to the base, with its output shaft connected to the guide rail base. This design allows the guide rail base to be quickly and accurately rotated in and out of the assembly table, enabling seamless transitions between step assembly and coding.

[0022] In summary, the present invention has at least one of the following beneficial technical effects:

[0023] 1. This utility model integrates the mounting base, base, and guide rail base on the side of the assembly table.

[0024] 2. The utility model utilizes a rotating mechanism to quickly and accurately move the guide rail base out of the way of the assembly table when needed, leaving ample space for step assembly operations. Once assembly is complete, the rotating mechanism rotates the guide rail base back onto the assembly table for laser marking. This design not only ensures operational safety but also improves operational smoothness, reducing downtime and adjustment time caused by equipment interference, further increasing production efficiency.

[0025] 3. The present invention provides a support arm on the guide rail seat. When the guide rail seat enters above the assembly table, one end of the support arm contacts the upper end surface of the assembly table. This design effectively solves the problem of bending and deformation that may occur when the guide rail seat moves over long distances. In particular, when the assembly table has a large lateral dimension, the support arm can provide additional support force to ensure the stability and rigidity of the guide rail seat, thereby improving the accuracy and reliability of laser coding. The support arm is designed to be a retractable structure in the height direction.

[0032] The following is combined with Figure 1-5 The utility model is described in further detail.

[0033] Example 1:

[0034] like Figures 1 to 3 As shown, an embodiment of the present invention discloses a laser coding device for steps, comprising a mounting seat 2 arranged on a side of an assembly platform 1 , a base 3 arranged on the mounting seat 2 , and a guide rail base 4 connected to the base 3 .

[0035] A first slide rail 7 is provided on the side of the assembly platform 1, extending along the height direction of the assembly platform 1. The mounting base 2 is provided on the first slide rail 7 and is driven to move on the first slide rail 7 by a motor-screw mechanism. A slide groove 8 is provided on the mounting base 2, extending along the longitudinal direction of the assembly platform 1. The base 3 is provided in the slide groove 8 via a slider 9, and is driven to move in the slide groove 8 by a motor-screw mechanism.

[0036] The guide rail base 4 is connected to the base 3 via a rotating mechanism. In this embodiment, the rotating mechanism is a rotating motor 10, which is fixed to the base 3. The output shaft of the rotating motor 10 is connected to the guide rail base 4. The rotating mechanism can rotate the guide rail base 4 out of or into the assembly table 1.

[0037] A laser marking head 5 is mounted on the guide rail seat 4 and can be moved and locked along the guide rail seat 4. The mounting base 2 can be moved and locked along the height of the assembly platform 1. The base 3 can be moved and locked along the longitudinal direction of the assembly platform 1. In this embodiment, a guide rail groove 41 is provided on the guide rail seat 4. The laser marking head 5 is positioned within the guide rail groove 41 via a guide block 11, which is driven to slide within the guide rail groove 41 by a motor-screw mechanism.

[0038] The working process of a laser coding device for steps in this embodiment is as follows:

[0039] When the step assembly operation is being carried out on the assembly table 1, the rotating motor 10 is activated to drive the guide rail seat 4 to rotate and move the guide rail seat 4 out of the assembly table 1, so that the guide rail seat 4 will not interfere with the workpiece equipment and related fixtures on the assembly table 1. After the step assembly operation is completed and the related equipment is reset, the rotating motor 10 drives the guide rail seat 4 to rotate and rotate the guide rail seat 4 to the top of the assembly table 1, and makes the guide rail seat 4 parallel to the horizontal direction of the assembly table 1. Through the action of each motor screw mechanism, the laser coding head 5 can be driven to move in the three directions of XYZ, so that the laser coding head 5 can be controlled to perform laser coding operations on the steps on the assembly table 1, and the coding efficiency is high. After the laser coding is completed, the rotating motor 10 drives the guide rail seat 4 to rotate and move the guide rail seat 4 out of the top of the assembly table 1, so that the assembly operation of the next workpiece can be completed.

[0040] Example 2:

[0041] Reference Figure 4 and Figure 5 The rest of this embodiment is the same as that of Embodiment 1, except that a support arm 6 is further provided on the guide rail base 4. When the guide rail base 4 enters the upper portion of the assembly platform 1, one end of the support arm 6 contacts the upper end surface of the assembly platform 1. When the assembly platform 1 is relatively large in the horizontal direction, the workpiece to be laser-coded is also relatively far from the mounting base 2. In this case, the guide rail base 4 is relatively long. Moreover, when the laser coding head 5 moves to the end away from the mounting base 2, the end of the guide rail base 4 away from the mounting base 2 is subjected to greater pressure, making the guide rail base 4 susceptible to bending and deformation. The support arm 6 can provide a certain degree of support, thereby extending the service life of the guide rail base 4.

[0042] In order to ensure that the guide rail seat 4 can be supported at any height from the upper end surface of the assembly table 1, in this embodiment, the support arm 6 is set to a structure that is retractable in the height direction. Specifically, the support arm 6 includes a shell 61, which is connected to the guide rail seat 4. A cylinder 62 is provided in the shell 61, and one end of the piston rod 63 on the cylinder 62 is connected to a guide wheel 64. The cylinder 62 is actuated to drive the piston rod 63 up and down, thereby adjusting the length of the support arm 6 so that when the guide rail seat 4 is above the assembly table 1, the bottom end of the support arm 6, that is, the guide wheel 64, always maintains contact with the assembly table 1.

[0043] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
