Description

一种激光打标振镜片的防抖结构及包含其的振镜腔 技术领域
本发明属于激光打标设备技术领域，具体涉及一种激光打标振镜片的防抖结构以及包括该防抖结构的振镜腔。
背景技术
目前市场上的激光打标机中大部分都使用了振镜系统，所述振镜系统包括振镜电机和振镜片，振镜片的一端与振镜电机的输出轴固定连接，通过振镜电机驱动振镜片进行摆动，实现对入射激光束角度的调整，调整角度后的激光束打在被打标物上，形成所需的图案。但打标过程中振镜片的高速摆动使得振镜片的另一端很容易发生不期望的抖动，进而引起振镜片整体抖动，尤其是为了使光束扫描范围更全面，打标机上的振镜片往往做的很宽很薄，这样振镜片的抖动会加剧，使入射到振镜片上的激光束角度发生偏离，不能按照预先设定的角度进行反射，使打标形成的图案产生偏移和误差。当激光束发生严重偏移时会对操作人员造成伤害。因此，如何减小及防止打标过程中振镜片的抖动是发明人所关注的重点。

具体实施方式
下面结合附图对本发明的具体实施方式作进一步说明：
实施例一：
参照附图1至附图3所示，一种激光打标振镜片的防抖结构，包括振镜片1、振镜电机2和用于固定振镜电机2的竖向设置的支撑板3，所述振镜电机2的输出轴21贯穿支撑板3与振镜片1一端连接，用于驱动振镜片转动。还包括固定架4、设于固定架4上的转动支撑部8以及用于夹持振镜片1另一端1a的夹持部5。
夹持部5与转动支撑部8转动连接。所述固定架4上设有螺孔,螺孔的轴向与夹持部5的转动轴线方向重合，转动支撑部8与所述螺孔相互匹配螺接。所述夹持部5依次包括第一夹头51、位于第一夹头51背面的第二夹头52、安装件6和转动件7。
如附图1至附图9所示，所述第一夹头51上设有与振镜片另一端1a形状匹配的卡槽53，振镜片另一端1a被相对固定在所述卡槽53内。第二夹头52可左右开合，包括左夹持块521和右夹持块522，其中右夹持块522与第一夹头51一体设置，左夹持块521和右夹持块522中心部位均设有缺口，左夹持块521和右夹持块522通过销钉52a相接合后，对应 的缺口形成夹持孔54，用于将安装件6的尾端62紧密固定在夹持孔54内。安装件6的前端61设有通孔61a。
转动件7的尾端71嵌套连接在安装件的通孔61a内。所述转动件7的前端(即靠近转动支撑部8的一端)设有顶珠伸缩孔，顶珠伸缩孔具有一朝向转动支撑部8的开口，开口直径小于孔内直径；顶珠伸缩孔从孔内向开口处依次设有压簧73和顶珠72，顶珠72的直径大于所述开口的直径，顶珠72在压簧73作用下部分凸出于所述开口外。所述固定架4与振镜片1平行设置，固定架4的一端41固定连接在支撑竖板3上，固定架与转动支撑部连接的一端42悬空。
所述转动支撑部8的一端81固定在固定架42端的外侧，另一端82贯穿固定架42端与转动件7转动连接，转动支撑部的端部82上具有与顶珠72凸出部分形状匹配的凹腔82a，顶珠72的凸出部分顶住所述凹腔82a的内壁。
本实施例的防抖结构的工作原理如下：振镜片1的一端与振镜电机2的输出轴21固定连接，振镜片1的另一端1a被固定在第一夹头51上的卡槽53内，安装件6的尾端62被夹持在第二夹头52的夹持孔54内，转动件7的尾端71嵌套连接在通孔61a内，使振镜片和夹持部之间相对固定，转动支撑部8固定在固定架4上，转动件7的顶珠72顶紧所述转动支撑部8的凹腔82a内壁。进行激光打标时，振镜片1和夹持部5在振镜电机2的驱动下同步转动，如此设计使得振镜片的端部被夹持固定，且其夹持部随振镜片同步转动，避免了打标时振镜片的不必要抖动，大大提高了打标精度和稳定性。在实际使用过程中可根据具体打标需要，通过调节转动支撑部8在固定架4上的螺接位置来调节夹持部5与振镜片1之间在轴向方向上的夹持松紧程度，提高了打标精度及操作方便性，使打标过程更加安全。
参照附图1和附图10所示，一种设有上述防抖结构的激光打标机的振镜腔，包括振镜片1、振镜电机2、安装振镜电机2的竖向支撑板3、振镜片11、振镜电机22和安装振镜电机22的支撑横板23。振镜片11和振镜片1分别控制打标的X轴向和Y轴向。所述振镜电机2的输出轴贯穿竖向支撑板3与振镜片1连接，所述振镜电机22的输出轴贯穿横向支撑板23与振镜片11连接。固定架4的一端41固定在向支撑板3上，固定架4与转动支撑部8连接的一端42悬空在振镜腔内，转动支撑部8固定连接在弯折端42的端头。振镜片1的一端部1a被夹持固定在夹持部5上，夹持部5与转动支撑部8转动连接，振镜片11在振镜电机22的驱动下转动，振镜片1在振镜电机2的驱动下和夹持部5一体转动。在振镜腔的一侧设有激光入口3a，从激光入口入射到振镜腔内的激光束，先打到转动的振镜片11上，经振镜片11反射至振镜片1上，振镜片1在防抖结构作用下快速摆动，对激光束进行扫描，使激光束打在被打标物件上形成所需图案。
实施例二：
参照附图11至附图18所示，一种激光打标振镜片的防抖结构，包括振镜片1a、振镜电机2a和用于固定振镜电机2a的竖向设置的支撑板3a，所述振镜电机2a的输出轴21a贯穿支撑板3a与振镜片1a一端连接。还包括固定架4a、轴承7a和用于夹持振镜片1a另一端1aa的夹头5a。夹头5a上设有转动轴6a。
所述固定架4a与振镜片1a平行设置，固定架4a的一端41a固定连接在支撑板3a上，固定架4a的另一端42a弯折，其上设有容置孔42aa，轴承7a安装在该容置孔内。所述夹头5a和轴承7a通过转动轴6a转动连接。
所述夹头5a包括第一夹头51a和第二夹头52a，所述第一夹头51a上设有与振镜片另一端1aa形状匹配的卡槽53a，振镜片另一端1aa被相对固定在所述卡槽53a内。第二夹头52a可左右开合，包括左夹持块521a和右夹持块522a，且右夹持块522a与第一夹头51a一体设置，左夹持块521a和右夹持块522a中心部位均设有缺口，左夹持块521a和右夹持块522a通过销钉52aa相接合后，对应的缺口形成夹持孔54a，用于将转动轴6a的尾端62a紧密固定在夹持孔54a内。转动轴6a的前端61a贯穿入所述容置孔42aa，且与轴承7a的内壁紧密贴合。
本实施例的防抖结构的工作原理如下：振镜片1a的一端与振镜电机2a的输出轴21a固定连接，振镜片1a的另一端1aa被固定在第一夹头51a上的卡槽53a内，转动轴6a的尾端62a被夹持在第二夹头52a的夹持孔54a内，转动轴6a的另一端61a贯穿入轴承7a的空腔内，转动轴6a外壁与轴承内壁相互贴合。进行激光打标时，振镜片1a和夹头5a在振镜电机2a的驱动下同步转动，同时轴承7a的滚珠72a带动轴承内壁和转动轴6a一起转动，如此设计使得振镜片的另一端被夹持固定，且夹头随振镜片同步转动，避免了打标时振镜片的不必要抖动，大大提高了打标精度和稳定性。
参照附图11和附图19所示，一种设有上述防抖结构的激光打标机的振镜腔，包括振镜片1a、振镜电机2a、安装振镜电机2a的竖向支撑板3a、振镜片11a、振镜电机22a和安装振镜电机22a的横向支撑板23a。振镜片11a和振镜片1a分别控制打标的X轴向和Y轴向。所述振镜电机2a的输出轴贯穿竖向支撑板3a与振镜片1a连接，所述振镜电机22a的输出轴贯穿所述横向支撑板23a与振镜片11a连接。固定架4a的一端41a固定在竖向支撑板3a上，固定架上安装有轴承7a的一端42a悬空在振镜腔内。振镜片1a的1aa端被夹持固定在夹头5a上，振镜片11a在振镜电机22a的驱动下转动，振镜片1a在振镜电机2a的驱动下和夹头5a同步转动。在振镜腔的一侧设有激光入口3aa，从激光入口入射到振镜腔内的激光束，先打到转动的振镜片11a上，经振镜片11a反射至振镜片1a上，振镜片1a在防抖结构作用下快速摆动，对激光束进行扫描，使激光束打在被打标物件上形成所需图案。
根据上述说明书的揭示和教导，本发明所属领域的技术人员还可以对上述实施方式进行变更和修改。因此，本发明并不局限于上面揭示和描述的具体实施方式，对发明的一些修改和变更也应当落入本发明的权利要求的保护范围内。此外，尽管本说明书中使用了一些特定的术语，但这些术语只是为了方便说明，并不对本实用新型构成任何限制。
