Definitions

  • the invention is used in the technical field of biomedical experimental instruments, and specifically relates to a glass slide printing device.
  • a glass slide is a commonly used transparent carrier in the biomedical field. It is generally made of glass and other materials with good light transmission. It is usually placed under a microscope to carry cells or biological sample slices for observation, reading and analysis by researchers or equipment. The slide-loaded samples usually require multi-process solvent immersion treatment before analysis to obtain better observation results.
  • the glass slide is usually divided into a sample carrying area and a labeling area. The sample carrying area is used to place a cell or biological sample, and the labeling area can be used to add marks to record relevant information.
  • Slide printing refers to the technique of adding information marks to the marking area on the slides and ensuring reliable long-term storage of the marked information.
  • the current marking methods can be divided into traditional marking methods and automatic marking methods.
  • the traditional marking method is for personnel to manually fill in the relevant information, and the tool often uses a pencil (because some samples may need to be processed in organic solvents, especially in the medical field).
  • the traditional marking method is difficult to unify writing specifications, the handwriting is easy to be blurred, and it is laborious and laborious. Prone to writing errors, etc., has been difficult to meet the needs of glass slide marking; automatic marking is a method of marking on the glass slide marking area with automated equipment, currently mainly laser coding, mechanical engraving, inkjet printing, ribbon printing, etc.
  • Laser coding relies on laser vaporization of the surface coating of the marking area to form marks, and mechanical engraving is to mechanically wear the surface of the glass slide or process the surface coating of the marking area to form marks. Both methods have certain requirements for the marking area. For example: it cannot be an uncoated frosted glass surface, the coating is sensitive to the laser absorption used, the coating adhesion is sufficient and it is not easy to peel off, etc., and the printing is a negative effect, the contrast is not good, and the practicality is limited; inkjet printing is due to the need Adopting a special light-curing process to increase the processing time, and the poor ink-jet adhesion of the marking surface does not easily increase the printing resolution, so the application range is limited.
  • the ribbon printing method uses a heated print head to match a specific ribbon to print information to the marking area of the slide.

  • the belt feeding mechanism and the glass slide horizontal conveying mechanism remain static, the print head moves horizontally or vertically above the ribbon, the carbon ribbon and the glass slide remain relatively static, avoiding the friction between the ribbon printing area and the ribbon, and ensuring the printing performance Quality and ribbon breakage.
  • the device guarantees the static state of the slide horizontal conveying mechanism during printing, the gap between the slide slides in the positioning bin of the slide trolley will still cause the slide of the slide, resulting in poor printing quality or broken ribbon happensing.

Description

玻片打印装置 技术领域
本发明用于生物医学实验仪器技术领域,具体涉及玻片打印装置。
背景技术
玻片是生物医学领域常用的一种的透明载体,一般为玻璃等材料,透光性好,通常置于显微镜下承载细胞或生物样本切片以供研究员或设备进行观察读取分析。玻片承载样本通常在分析前需要多流程的溶剂浸泡处理以获得较好的观察效果。玻片上通常划分为样本承载区与标记区,其中样本承载区用来放置承载细胞或生物学的样本,标记区可用于增加标记以记录相关信息。
在实验操作过程中,研究员针对同一样本常需要多块玻片进行平行对比分析,不同的玻片间需要标记以进行区分。而在医用病理诊断中,玻片大量应用于组织检查、血液分析、细胞学分析等,不同病人之间,不同的样本之间,都需要信息标记以有效区分,便于样本流程传递或实体长期的留档存储。
玻片打印是指在玻片在标记区增加信息标记,且保证标记信息可靠长期存储的技术。目前标记方法可分为传统标记法和自动标记法。传统标记法是人员手动填写相关信息,工具常采用铅笔(因为有些样本可能需要在有机溶剂中处理,尤其在医用领域中),传统标记法因标注难以统一书写规范、字迹易模糊、费事费力、易于书写出错等一直难以满足玻片标记的需求;自动标记法是采用自动化的设备在玻片标记区进行标注的方法,目前主要是激光打码、机械雕刻、喷墨打印、色带打印等。激光打码是靠激光气化标记区表面涂层以形成标记、机械雕刻是在玻片表面机械磨损或加工标记区表面涂层以形成标记,这两种方法均对标记区域有一定的要求,例如:不能是无涂层的磨砂玻璃面,涂层对所用激光吸收敏感,涂层附着力足够不易连带剥落等,且打印是负片效果,对比度不佳,实用性受到限制;喷墨打印由于需采用特殊的光固化工艺增加处理时间,且标记面对喷墨附着力不佳不易提高打印分辨率,故应用范围有限。色带打印法采用加热的打印头,配合特定的色带,将信息打印到玻片标记区的方法。目前市面上的色带打印机常应用于特定规格的载玻片,通用性不强,且在色带控制上大多数并没有进行精细的控制设计,易发生色带绕曲或拉断的情况。
CN107284045A涉及一种玻片印刷装置,其包括预热机构、打印机构、玻片输送机构 和出仓堆叠机构等,通过对玻片进行预热后打印,以提升打印质量。该装置的取片机构采用上下层叠式布置方式,玻片输送机构每次从取片仓底端取出最底端的玻片。玻片在取片仓内依靠层叠玻片的重力进行压紧,当仓内存放有大量玻片时,最底端的玻片因承受较大的重力而取出困难;当仓内存放少量玻片时,最底端的玻片因压力较小而松动定位,易发生取片定位不准确甚至卡死的故障。
CN108189564A涉及一种载玻片打印机,其包括输送装置、喷墨装置和固化装置,采用热固化的工艺在玻片标记区进行打印;其取片机构也采用上下层叠式布置方式,但增加减重机构,控制最底端的玻片上方玻片的数量,以优化控制取片的压力;增加倾斜机构,便于玻片出仓后进入传输装置。该装置增加在取片仓两端的翻转式减重机构,在往下方增加玻片后重新复位时易发生夹碎玻片的风险。
CN105082782A涉及一种载玻片打印装置及方法,其包括碳带进给机构、玻片水平输送机构、打印头固定组件、打印头水平驱动机构、打印头垂直驱动机构及移动座,打印时,碳带进给机构和玻片水平输送机构保持静止,打印头在碳带上方水平或者垂直移动,碳带与玻片保持相对静止,避免了碳带打印区与碳带的相互摩擦,保证了打印的质量和碳带拉断的情况。该装置虽然在打印时保证了玻片水平输送机构的静止,但在玻片小车的定位仓内,安放玻片的间隙仍然会造成玻片的滑动,造成打印质量不高或碳带拉断的情况。色带驱动控制在打印之前总是需要反复调整色带,降低了工作效率。
CN103201115A涉及一种用于组织标本载玻片的彩色打印机系统,其包括标本接收结构、油墨接收装置、打印头、驱动机构和控制系统,其采用特殊的多色格色带以实现彩色打印的效果。但该装置拨片仓采用玻片上下层叠式布置方式,取出片仅依靠胶轮与最底层玻片之间的摩擦力进行出片,易发生上述取片困难的情况。玻片打印后依靠传送带进行传输,也是十分的繁琐。
CN108068470A涉及一种玻片书写仪,其包括玻片盒、打印装置、输送机构和传输口,该装置在玻片打印头打印后,采用四连杆的输送机构将玻片输送至最终收片口,连杆机构运动需要依靠输送机构底端的滑轮进行驱动,玻片传输速度较慢,连续打印之间间隔时间较长,打印效率不高。

具体实施方式
应理解,在本发明范围内中,本发明的上述各技术特征和在下文(如实施例)中具体描述的各技术特征之间都可以互相组合,从而构成优选的技术方案。
在本发明的描述中,涉及相关术语“前”、“后”、“左”、“右”、“上”、“下”、“水平”、“竖直”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有的特定方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。
本发明提供一种玻片打印装置,针对玻片打印过程中的取片、传输、打印、收片四个步骤环节,包括出片单元、玻片输送单元、打印头单元、打印定位单元、色带单元和收片单元。所述装置的出片单元具有侧叠式玻片仓组件,该玻片仓组件允许玻片放置方向为玻片的可标记面或其背面与玻片自身的重力方向平行或形成一定小角度,如0~45°。出片单元设有的玻片仓预压组件提供侧叠玻片垂直于玻片打印面的压力,保证玻片在恒定压力下进行取片,实现玻片仓组件取片的精确控制。要实现玻片在标记区完成内容标记后,玻片可以在有机溶剂如乙醇、二甲苯等有机溶剂中长期浸泡而标记内容耐腐蚀,该装置采用色带单元配合玻片在打印头单元下快速打印。该打印装置中,打印头单元的打印头支架可自动调整,可以消除打印头打印平面与玻片标记平面之间的间隙,保证两者紧密贴紧;色带装置可分别控制收带组件和放带组件两者之间的收放驱动配合,可实现打印时色带的精确收放,以及自动反馈放带组件的色带量和色带是否断开的情况;打印过程中,打印定位单元对正在打印的玻片进行位置定位,保证玻片与玻片输送单元之间相对静止;打印完成后,玻片输送单元依靠输送滑道快速将玻片传递至可自动堆叠收片的收片单元内。除上述单元外,该装置还可包括相关的传感器、温控和系统总控单元,对整个打印过程进行实施监控、数据采集和有效反馈,具有操作自动化、稳定性好、打印质量高、工作效率高的优点。
因此,本发明的新型玻片打印系统包括:出片单元、玻片输送单元、打印头单元、打印定位单元、色带单元、收片单元以及监测和控制上述各单元的系统总控单元。以下对本发明的玻片打印系统的各个部件进行描述。应理解,这些描述仅仅是阐述性的,并非意图限制本发明的范围。
出片单元
出片单元用于存放待打印的玻片。本发明的出片单元的结构设计成允许玻片侧叠而非平堆放置于其玻片存放空间内,即玻片的可标记面或其背面与玻片自身的重力方向平行或形成一定小角度,如0~45°。
出片单元包括玻片仓组件、玻片仓预压组件、预压导向组件和预压动力组件。
玻片仓组件用于存放待打印的玻片,并允许存放的玻片在仓内集体滑动。玻片仓组件内设有存放玻片的空间。通常,该空间可容纳至少150片玻片,如150~200片玻片。
玻片仓组件设置有构成玻片仓组件存放玻片空间的前、后、左、右、底五个面的仓件,分别称为前侧仓件、后侧仓件、左侧仓件、右侧仓件和底侧仓件。底侧仓件承载侧叠放置的玻片底侧;左侧仓件和右侧仓件辅助定位侧叠玻片的两侧端面;前侧仓件包括左右两块仓件,分别在左右两侧限制侧叠玻片的背面(即可标记面的背面)。前侧仓件和后侧仓件负责连接左侧仓件、右侧仓件和底侧仓件,形成玻片仓组件整体。底侧仓件前端部分抵住或完全未抵住前侧仓件的左右两块仓件,以留出玻片下滑的通道。通常,该通道仅满足一片玻片下滑。前侧仓件的左右两块仓件之间间隔一定距离,且左右两块仓件均具有一定厚度,因此,在左右两块仓件相对的两个面之间形成了一个供玻片输送单元的玻片输送组件滑动的取片槽。玻片仓组件可保持一定小角度的倾斜,便于侧叠玻片与前侧仓件的限制定位,倾斜角度可在0~45°之间,优选为0~30°,更优选为约10°。
玻片仓组件内还可设置有玻片滑动辅件,可设置在底侧仓件和/或设置在左侧仓件与右侧仓件上,与侧叠玻片直接接触。玻片滑动辅件不仅可用于辅助承载仓内玻片,还可用于减小玻片滑动的摩擦阻力,便于侧叠玻片整体的滑动。玻片滑动辅件可为圆柱形导轨或方形导轨等,接触玻片表面优先进行硬化处理,以增加耐磨性和使用寿命,便于侧叠玻片的滑动。
玻片仓组件中还可设置有温控单元,可设置在底侧仓件和/或设置在左侧仓件与右侧仓件上,其对仓内的玻片进行温升预热,提高玻片在打印时的温度。温控单元可采用加热片、半导体等,由系统总控单元进行温度监控。可采用市售的温控单元。
玻片仓组件中还可设置有光学传感器,可设置在玻片仓组件内的前侧仓件和/或后侧仓件上,用于检测仓内玻片的放置方向。光学传感器根据玻片中可标记区与非标记区对光传输反射后能量的不同进行识别。光学传感器可以是反射式光电传感器或者结合的透射式光电传感器。光电传感器通常由光源和接收器两部分组成。可采用市售的光学传感器。
玻片仓预压组件用于限制定位侧叠玻片可标记面,并在该面上保持一定的压力。玻片仓预压组件包括预压推块,该预压推块抵住玻片的可标记面,并保持一定压力。仓内侧叠玻片在玻片仓预压组件的作用下滑动至玻片输送单元的玻片传输组件的支撑面上,此时侧叠玻片的背面与前侧仓件相接触,可标记面与玻片仓预压组件的预压推块相接触,玻片仓预压组件的压力将侧叠玻片压紧贴合在玻片传输组件上,并始终保持压紧状态。当最前端的玻片出片时,侧叠玻片在玻片仓预压组件的推动下整体平行向前移动一块玻片的距离。
预压导向组件连接玻片仓预压组件,并控制玻片仓预压组件的运动方向。预压动力 组件用于提供玻片仓预压组件运动的动力。预压导向组件和预压动力组件可采用通过丝杆螺母传动、皮带传动、齿轮齿条传动和直线导轨传动等单一或组合方式进行导向与传动。预压动力组件的动力源为电机。
预压导向组件可包括滑动导轨,滑块和滑块连接块。预压动力组件可包括产生动力的电机和动力传送装置,包括但不限于齿轮、轴承、同步带和同步带固定块等。
滑动导轨起到滑动导向的作用,用于控制滑块的滑动方向,从而控制玻片仓预压组件的滑动方向。滑块固定在滑块固定块上,与滑动导轨相配合,可在电机产生的动力驱动下沿着滑动导轨滑动。滑块连接块用于固定滑块,并连接预压推块。滑块连接块还与动力传送装置中的同步带固定块相配合,将同步带固定压紧在两者之间。电机产生的动力通过同步带和滑块连接块传输至预压推块。
预压动力组件可通过丝杆螺母传动、皮带传动、齿轮齿条传动和直线导轨传动等单一或组合方式将电机产生的动力传输至预压推块。例如,在某些实施方案中,动力传送装置包括电机齿轮、过渡齿轮、过渡齿轮轴、过渡齿轮轴承、步带齿轮、步带齿轮轴、步带齿轮轴承、主步带轮、副步带轮、副步带轮轴、副步带轮轴承、同步带和同步带固定块等。可将同步带的两端固定在主步带轮、副步带轮之间,副步带轮固定在副步带轮轴上,副步带轮轴承的轴承内圈配合副步带轮轴,轴承外圈配合打印系统的支撑面板上。主步带轮和步带齿轮可固定在步带齿轮轴上,步带齿轮轴承的轴承内圈配合步带齿轮轴,轴承外圈配合在打印系统的支撑面板上。步带齿轮通过销键等固定在步带齿轮轴上。步带齿轮受到驱动力时,连同步带齿轮轴和主步带轮共同转动。电机齿轮则设在电机的电机轴上,过渡齿轮设在电机齿轮与步带齿轮轴之间,将电机齿轮的动力过渡传输至步带齿轮上。过渡齿轮可包括两段齿轮,分别与电机齿轮和步带齿轮轴保持齿轮啮合;过渡齿轮轴采用螺纹、销钉等连接方式固定在支撑面板上。电机还可配有可进行电机控制的编码器。电机产生的动力依次经由电机齿轮、过渡齿轮、过渡齿轮轴、过渡齿轮轴承、步带齿轮、步带齿轮轴、步带齿轮轴承、主步带轮、副步带轮、副步带轮轴、副步带轮轴承和同步带固定块传送到同步带上,再经由同步带和滑块连接块传输至预压推块。
出片单元还设置有编码器,编码器与电机单独设置/或装在或或融合在电机上,用于转换电机驱动信号。编码器还可记录和分析电机运行状态,计算出目前玻片仓组件中玻片的数量,由此可对玻片仓组件中的侧叠玻片进行自动计数。此外,可由编码器直接控制电机的输出转矩,从而可对玻片仓组件中的侧叠玻片控制输出恒定的压力。
出片单元还包括位于玻片仓组件前端的前端连接件和位于玻片仓组件后端的后端连接件。前端连接件用于连接出片单元与玻片输送单元,后端连接件则用于将出片单元固定 在支撑面板。
玻片输送单元
玻片输送单元用于输送玻片,包括打印输送单元和滑动输送单元。打印输送单元用于从出片单元中装载玻片、打印前和打印中输送玻片。滑动输送单元用于连接打印输送单元和收片单元,将打印输送单元中输送的已完成打印的玻片输送至收片单元中。
打印输送单元包括玻片输送组件、输送导向组件和输送动力组件。
玻片输送组件是装载和输送玻片的载体,包括用于承载待打印玻片的玻片打印匣和输送固定件。玻片打印匣设置在打印输送单元的玻片输送组件中,用于承载玻片。玻片打印匣结合或连接在输送固定件上。玻片打印匣正对玻片一面设有容纳玻片的空间,该空间的长度、宽度和深度与玻片的长度、宽度和深度相适应,正好容纳下一块玻片。玻片在玻片打印匣中可标记面正对打印头。玻片输送组件还设置有输送挡块,其固定连接在输送固定件上,并位于玻片打印匣的上方,用于在取片槽中定位并限制玻片仓组件内玻片的背面,其与玻片仓预压组件配合分别承载玻片仓组件内玻片的背面和可标记面。在某些实施方案中,输送挡块构成玻片打印匣的一部分,其底侧构成玻片打印匣上容纳玻片的空间的一个侧面。输送挡块位于与玻片打印匣布置在玻片输送组件紧贴玻片的一侧。
当不取片时,输送挡块紧贴玻片背面,阻挡玻片进入玻片打印匣内和进入玻片下滑通道内。通常,输送挡块向玻片仓组件的内部凸出一定的距离,以实现该阻挡目的;该距离通常为一片玻片的厚度,即通常为玻片下滑的通道的厚度。此时,玻片打印匣位于前侧仓件的左右仓件之间,其容纳玻片的空间未正对玻片,存在一定的错位,该空间的底面基本上与左右仓件内侧面(即构成玻片仓组件的那一侧)平行。取片时,玻片输送组件向上移动,使得输送挡块移离所处位置,露出玻片打印匣的完整空间,从而使得玻片在出片单元预压推块的推力作用下进入玻片打印匣,完成出片。当玻片输送组件输送入玻片打印匣的玻片时,输送挡块随着玻片打印匣一起移动,并紧贴出片单元最前端的玻片的背面滑动,阻止其向前移动。
玻片输送组件在输送导向组件限定的输送路径上滑动。该输送路径包括三个特定的位置,分别为玻片装载位置、玻片打印位置和玻片出匣位置。玻片装载位置为玻片从出片单元进入玻片打印匣的位置;玻片打印位置为玻片在打印头单元下开始打印的位置;玻片出匣位置为玻片从玻片打印匣脱离的位置。工作时,玻片输送组件按照输送导向组件的输送方向滑动至玻片装载位置时,此时输送挡块解除对玻片背面的限制,玻片打印匣正对侧叠玻片出片位置,玻片仓预压组件推动侧叠玻片向玻片打印匣滑动,最前端的一张玻片装载入玻片打印匣中;完成玻片的装载后,玻片输送组件整体继续向玻片打印位置滑动。
输送导向组件连接玻片输送组件,并控制玻片输送组件的运动路径。输送动力组件用于提供玻片输送组件运动的动力。输送导向组件和输送动力组件可通过丝杆螺母传动、皮带传动、齿轮齿条传动和直线导轨传动等单一或组合方式进行导向与传动。输送动力组件的动力源为电机。
输送导向组件包括滑动导轨、滑块和输送支件。输送动力组件包括产生动力的电机和动力传送装置,包括但不限于齿轮、轴承、同步带和同步带固定块等。
滑动导轨固定连接在输送支件上,起到滑动导向的作用,用于控制滑块的滑动方向,从而控制玻片输送组件的滑动方向。滑块固定连接在输送固定件上,与滑动导轨相配合,可在电机产生的动力驱动下沿着滑动导轨滑动。输送支件还可将整个玻片输送单元固定连接在打印系统的支撑面板上。
输送动力组件可通过丝杆螺母传动、皮带传动、齿轮齿条传动和直线导轨传动等单一或组合方式将电机产生的动力传输至玻片输送组件。例如,在某些实施方案中,动力传送装置包括电机齿轮、过渡齿轮、过渡齿轮轴、过渡齿轮轴承和齿条。齿条固定连接/或结合在输送固定件上。电机固定在输送支件上。电机齿轮则设在电机的电机轴上,过渡齿轮设在电机齿轮与齿条之间,将电机齿轮的动力过渡传输至齿条上。过渡齿轮可包括两段齿轮,分别与电机齿轮和齿条啮合;过渡齿轮轴采用螺纹、销钉等连接方式固定在输送支件上。电机产生的动力依次经由电机齿轮、过渡齿轮、过渡齿轮轴、过渡齿轮轴承传送到齿条和输送固定件上。
玻片输送单元还设置有编码器,编码器单独设置、或装在电机上、或融合在电机上。可由编码器控制电机输出的动力,从而控制玻片输送组件的运动速度,尤其是控制玻片输送组件在玻片打印位置时保持运动速度恒定。在玻片打印位置时,玻片输送组件、玻片和色带三者保持相对静止(色带在打印头以及打印头单元的压力下粘附在玻片上),在玻片输送组件的恒定速度下共同运动。色带在收带组件和放带组件中也以与上述相同的速度进行收放色带,保持收放色带速度的恒定。
滑动输送单元包括滑道件和出匣件。滑动输送单元在玻片输送单元的玻片出匣位置接受弹出的玻片,将其输送至收片单元。出匣件用于推动玻片打印匣中的玻片的某个位置,使玻片从打印输送单元弹出,进入滑道件。滑道件包括形成玻片输送路径的滑道。
滑道可为弧形滑道,可依靠其他动力或仅采用玻片弹出时的速度和重力,在滑道中滑动至收片单元中。滑道件的滑道为类似于滑梯的弧形面,该面可减小玻片滑动的摩擦阻力,便于玻片的快速滑动。滑道接触玻片的表面优先进行硬化处理,以增加耐磨性和使用寿命。滑道件还可包括支撑滑道的支撑件和两侧限制玻片在滑道件内滑动方向的滑动挡边。

定位轮摆动组件由连接定位轮轴的摆动套件、摆动中心件和摆动动力件组成,定位轮摆动组件绕着摆动中心件转动,摆动套件与摆动动力件分别位于摆动中心件摆动支点的两侧。摆动套件用于固定定位轮轴,驱动定位轮摆动。摆动套件可包括一对轴承,其固定在定位轮轴上,用以驱动定位轮进行摆动。摆动中心件是定位轮摆动组件的摆动支点。摆动中心件可包括衬套螺钉和衬套,衬套紧配安装在摆动套件的衬套孔内,衬套螺钉穿过衬套的内孔,固定安装在系统的支撑面板上。摆动动力件提供摆动所需的驱动力。摆动动力件可为电机、弹簧等,例如为拉力弹簧。在某些实施方案中,摆动动力件包括拉力弹簧和弹簧件,弹簧一端固定在弹簧件上,另一端固定在摆动套件上,提供所需的拉力。
打印定位单元还可包括定位轮阻尼件,用于给定位轮的转动提供一定的阻尼,保证定位轮与匣内玻片之间的摩擦力,不会发生随意的滑动。定位轮阻尼件可包括压片弹簧、阻尼片和压片。阻尼片采用具有低摩擦力的高分子材料,如尼龙、POM和PTFE等。压片弹簧装在摆动套件和阻尼片之间,并提供一定的压力;压片紧贴阻尼片的另一侧面,保持压片弹簧的预压紧状态,并与定位轮轴不发生相对的滑动。当定位轮轴伴随定位轮转动时,压片与阻尼片也跟随定位轮轴发生转动,而摆动套件静止,阻尼片与摆动套件之间的摩擦力提供转动阻尼。定位轮阻尼保证定位轮与匣内玻片之间的摩擦力,有利于玻片在玻片打印匣内的定位,而不发生随意的相对滑动。
打印头单元
打印头单元是用于在玻片的可标记区进行打印的核心部件,包括打印头、打印头支撑组件、打印头导向组件、打印头动力组件和打印头修正组件。色带在打印头与玻片之间,打印时,打印头需保持一定的预压力将色带压在玻片上,才能保证打印头局部加热色带后色带的标记材料粘附在玻片上。打印头为市面上常见的打印头部件,打印头安装在打印头支撑组件上。
打印头支撑组件用于支撑打印头,具有修正组件孔、角度孔和支撑板连接端。修正组件孔具有用于安装打印头修正组件的沉头孔。角度孔用于限制打印头可自动修正的角度。支撑板连接端用于固定连接打印头导向组件的滑块固定块。
打印头导向组件连接打印头支撑组件,并控制打印头支撑组件的运动方向。打印头动力组件用于提供打印头支撑组件的运动动力。打印头导向组件和打印头动力组件可采用通过丝杆螺母传动、皮带传动、齿轮齿条传动、直线导轨传动等单一或组合方式进行导向与传动。打印头动力组件的动力源为电机。

具体实例
玻片1为玻璃材质,可标记区101为磨砂玻璃。色带70为耐溶性较好的树脂基碳带。玻片仓组件20内已放入多块玻片1,且各单元的动力组件均将系统恢复至初始状态。
打印预设置时,出片单元2中电机230驱动玻片仓预压组件21从初始零位运动压紧玻片1,此时电机230的编码器2301记录分析电机230从初始零位至压紧位置运动的距离,计算出目前玻片仓组件20中玻片1的数量;且出片单元2维持对玻片仓预压组件21恒定的压力。此时,底侧仓件200上的温控单元27,对仓内的玻片1进行温升预热,提高玻片1在打印时的温度。前侧仓件204上的光学传感器28初步检测仓内的玻片1是否放置方向有误,如有误则进行用户提醒。摄像头91记录外部信息的数据输入。
开始打印前,打印输送单元3的输送动力组件33电机330按照输送方向驱动玻片输送组件31从零位运动至玻片装载位置11时,此时输送挡块34解除对玻片1背面的限制,玻片打印匣30正对侧叠的玻片1的出片位置,玻片仓预压组件21推动侧叠的玻片1向玻片打印匣30滑动,最前端的一张玻片1装载入玻片打印匣30中;完成玻片1的装载后,玻片输送组件31整体继续向下方的玻片打印位置滑动。当玻片打印匣30不再正对侧叠的玻片1的出片位置时,输送挡块34恢复对玻片1背面的限制定位。色带单元7的放带组件71和收带组件72配合调整色带70;打印头单元6的打印头动力组件63驱动至打印待定位置。
在玻片打印位置,打印头支撑组件61上的光学传感器65先检测玻片打印匣30内的玻片1是否放置方向有误,若有误则继续运动至玻片出匣位置弹出玻片1。检测无误后,打印头60向玻片1的可标记区101运动,并保持一定的压力将色带70压在玻片1的可标记区101上;打印头修正组件64在压力下,在一定的角度范围内进行摆动,自动修正打印头60与玻片1的接触角度,消除打印头60打印平面与玻片1之间的间隙。此时,打印头60局部加热色带70后色带的标记材料粘附在玻片1上;同时玻片输送组件31、玻片1和色带70三者保持相同的恒定速度一起运动(色带70在打印头60以及打印头单元6的压力下粘附在玻片1上)。
色带70在放带组件71和收带组件72中也以与上述相同的速度进行放收色带70,并保持放收色带速度的恒定。放带组件71的放带电机718产生一个与色带70运动方向相反的转矩,形成放带的阻尼,从而保证放带部分色带70始终保持色带拉直状态;收带组件72的收带电机728产生一个与色带70运动方向相同的转矩,形成收带的拉力,从而保证色带70收带部分始终保持处于拉直状态。放收两段色带拉直可避免色带在打印时发生的弯曲或堆叠,提高打印质量。完成打印后,打印头单元6的打印头动力组件63驱动回收打印头60至打印待定位置。打印输送单元3的输送动力组件33按照输送方向驱动玻片输送组件31至玻片出匣位置。
在玻片出匣位置13时,滑动输送单元4的出匣件41使玻片1从玻片打印匣30弹出,进入滑动输送单元4的滑道件40中,依靠玻片1弹出时的速度和重力,在滑道41中滑动至收片单元8中,完成玻片1的打印。
打印输送单元3的输送动力组件33按照输送方向驱动玻片输送组件31恢复至初始零位;放带组件71与收带组件72完成更换和回收废色带。后续按照可进行重复的打印。
