Description
喷码机用液滴发生器 Drop generator for inkjet printer
技术领域 Technical field
本发明涉及一种喷码机的应用， 特别是指一种用于喷码机产生墨滴从而喷印点 阵信息的喷码机用液滴发生器。 The present invention relates to the use of a printer, and more particularly to a droplet generator for a printer for producing ink droplets by a printer to print dot matrix information.
背景技术 Background technique
目前国内外的喷码机基本上均采用压电陶瓷作为驱动扰动液体断裂成液滴， 从 而喷印点阵信息。 液滴发生器的工作原理是： 在压电陶瓷两端施加高频交变电压， 激励压电陶瓷高频伸缩， 从而驱动与压电陶瓷相连接的金属杆随压电陶瓷的髙频伸 缩的振动， 而金属杆下端与喷嘴出口处较近， 其下端的振动会对流经喷嘴出口处的 液流产生扰动， 这样扰动的液体流出喷嘴后会断裂成液滴， 其液滴发生的频率与压 电陶瓷两端所加交变电压的频率一致。 At present, the domestic and international inkjet printers basically use piezoelectric ceramics as the driving disturbance liquid to break into droplets, thereby printing dot matrix information. The working principle of the droplet generator is: Applying a high-frequency alternating voltage across the piezoelectric ceramic to excite the high-frequency expansion and contraction of the piezoelectric ceramic, thereby driving the metal rod connected to the piezoelectric ceramic to expand and contract with the piezoelectric ceramic. Vibration, and the lower end of the metal rod is closer to the nozzle outlet, and the vibration at the lower end will disturb the flow through the nozzle outlet, so that the disturbed liquid will break into droplets after flowing out of the nozzle, and the frequency and pressure of the droplets will occur. The frequency of the alternating voltage applied to both ends of the electric ceramic is the same.
而图 1所示目前市场上大多数喷码机厂家使用的喷腔基本结构， 典型的结构形 式如美国专利号 5， 457， 484。 采用这种结构在理想状况条件下可以产生比较好的液 滴， 从而获得理想的喷码信息， 但是采用该种结构存在以下几个方面的问题： （1 ) 工作性能稳定性不好， 液滴形态易变。 由于压电陶瓷本身的参数随温度、 负载等变 化表现出多变的物理特性， 采用图 1所示的结构压电陶瓷本身性能并不稳定。 首先 这种结构需要较高的激励电压， 发热大，温度变化明显， 从而导致参数稳定性不好， 另外与交变电压引线的焊接点的位置、 与金属杆的焊接牢固程度也会影响其负载的 变化， 从而影响其性能参数， 导致激励大小的变化， 产生的液滴随时间表现出不稳 定性， 从而影响喷码机的打字效果； （2) 机械结构稳定性差， 采用该种结构， 如 图 1中焊接或贴接处 5， 受压电陶瓷镀银层与压电陶瓷结合强度限制， 无论压电陶 瓷与腔体的连接采用胶粘结方式还是采用焊接方式均不能获得较高的剪切强度， 在 受到外界强烈冲击时或长期在恶劣环境工作时容易断裂或折断从而导致压电驱动 部分失效。 （3) 驱动性能参数较难控制， 由于压电陶瓷参数的不稳定性， 受负载、 温度等多种外界条件的影响， 从而导致发生器整体驱动性能的变化， 而这种结构对 这种性能变化的调整比较差， 所以驱动性能参数调整较难， 这在一定程度上增加了 生产制作的难度和生产成本。
发明内容 While the basic structure of the spray chamber used by most printer manufacturers on the market is shown in Fig. 1, a typical structural form is shown in U.S. Patent No. 5,457,484. With this structure, better droplets can be produced under ideal conditions, and the desired coding information can be obtained. However, the following problems exist in the structure: (1) The performance is not stable, and the droplets are The shape is variable. Since the parameters of the piezoelectric ceramic itself exhibit varying physical properties as a function of temperature, load, etc., the piezoelectric ceramics shown in Fig. 1 are inherently unstable in performance. First of all, this structure requires a high excitation voltage, a large heat generation, and a significant temperature change, resulting in poor parameter stability. In addition, the position of the solder joint with the alternating voltage lead and the degree of soldering to the metal rod also affect the load. The change, which affects its performance parameters, leads to changes in the size of the excitation, and the resulting droplets exhibit instability over time, thereby affecting the typing effect of the printer; (2) poor mechanical structure, using such a structure, such as In Figure 1, the soldering or bonding 5 is limited by the bonding strength between the piezoelectric ceramic silver plated layer and the piezoelectric ceramic. No matter whether the piezoelectric ceramic and the cavity are connected by glue bonding or welding, high shear can not be obtained. The cutting strength is easily broken or broken when subjected to strong external shock or long-term work in a harsh environment, resulting in failure of the piezoelectric driving portion. (3) The driving performance parameters are difficult to control. Due to the instability of the piezoelectric ceramic parameters, it is affected by various external conditions such as load and temperature, resulting in changes in the overall driving performance of the generator. The adjustment of the change is relatively poor, so the adjustment of the drive performance parameters is difficult, which increases the difficulty of production and the production cost to a certain extent. Summary of the invention

It can withstand a lot of pressure, and can not withstand large tension, especially the effect of dynamic tension. Therefore, applying a certain pre-stress on both ends of the piezoelectric ceramic plays a good role in the stability of the piezoelectric ceramic work. Thereby making up for the deficiencies in the prior art.
