[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0024] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0026] Reference Figure 1-7 A laser drawing instrument comprises a laser drawing instrument body 1 and a control substrate 4. The control substrate 4 is arranged inside the laser control instrument body. A CO2 laser generator 5 is arranged on one side of the top surface of the control substrate 4. A galvanometer adjustment mechanism 6 is arranged on the side of the CO2 laser generator 5. A reflector adjustment mechanism 9 is arranged on the other side of the top surface of the control substrate 4. A left-side drawing mechanism 7 and a right-side drawing mechanism 8 are arranged on both sides of the reflector adjustment structure. When the whole device is used for drawing a microelectrode, the left-side drawing mechanism 7 and the right-side drawing mechanism 8 clamp the two ends of the microelectrode respectively, and the CO2 laser generator 5 generates laser to the galvanometer adjustment mechanism 6. The galvanometer adjustment mechanism 6 reflects vibration to the reflector adjustment mechanism 9 to contact and heat the microelectrode, thereby providing drawing heat, so that the microelectrode can be drawn through the left-side drawing mechanism 7 and the right-side drawing mechanism 8 at both ends in a heated environment.

[0027] In order to increase the compatibility of the galvanometer adjustment mechanism 6 and the laser of the CO2 laser generator 5, the galvanometer adjustment mechanism 6 is provided to include a galvanometer body 601 and a pitch adjustment micrometer head 602. The surface of the control substrate 4 is screwed with an angle adjustment base 603, and the side of the angle adjustment base 603 is U-shaped. The two sides of the surface of the angle adjustment base 603 are respectively provided with a galvanometer body 601 and a pitch adjustment micrometer head 602. When the traditional galvanometer adjustment mechanism 6 adjusts the galvanometer pitch angle, the galvanometer lens may deviate from the laser irradiation range. The present application adopts a method in which the galvanometer pitch angle adjustment rotation center is coaxial with the laser center, thereby ensuring that the laser is always in the center of the galvanometer lens when adjusting the galvanometer pitch angle, and the laser will not deviate from the required reflection range after the laser is turned on.

[0028] In order to ensure the compatibility of the reflector and the galvanometer adjustment mechanism 6, the reflector adjustment mechanism 9 is provided including a vertical adjustment guide rail 901 and a reflector body 904. The bottom surface of the vertical adjustment guide rail 901 is connected to the surface of the control substrate 4 by screws. A Y-axis adjustment base 903 is provided on the top surface of the bottom end of the vertical adjustment guide rail 901. A Z-axis adjustment base 902 is provided in the vertical direction of the vertical adjustment guide rail 901. The side of the Z-axis adjustment base 902 is connected to the side of the reflector body 904. The reflector body 904 is adjusted in two directions through the Y-axis adjustment base 903 and the Z-axis adjustment base 902, so that the adjustment direction and position of the reflector body 904 correspond to the galvanometer body, thereby ensuring the consistency and correspondence of laser transmission.

[0029] Other limiting structures of the entire device are as follows: a display panel 2 is provided on the front of the laser drawing instrument body 1, and a control button 3 is provided on the side of the display panel 2. The control button 3 is electrically connected to the CO2 laser generator 5 to facilitate the control of laser heat. The vertical center line of the galvanometer adjustment mechanism 6 in the top-view direction coincides with the vertical center line of the reflector adjustment structure in the top-view direction. The left-side drawing mechanism 7 and the right-side drawing mechanism 8 are symmetrically distributed along both sides of the reflector adjustment mechanism 9 to ensure linear reception of laser transmission. The adjacent side connections on the outer surface of the laser drawing instrument body 1 are all rounded, and the surface of the display panel 2 on the laser control instrument body is an inclined surface with an inclination angle of 60 degrees. The galvanometer body 601 is located at one end of the angle adjustment base 603 close to the CO2 laser generator 5, and the center line of the CO2 laser generator 5 coincides with the center line of the galvanometer body 601. Specific embodiment 2:

[0031] Reference Figure 1-7 The key parameters of the laser drawing instrument body 1 include the energy of the CO2 laser generator 5, the amplitude width of the galvanometer, the key heat test, tension, speed, time, and delay. These parameters are the key factors to ensure the stable operation of the laser drawing instrument. The specific parameters are as follows:

[0032] CO2 laser generator 5 Energy: The heating temperature is controlled by adjusting the laser power. The greater the power, the higher the temperature.

[0033] Critical heat test: In order to set the appropriate heat value, the heat required to melt the glass must first be determined through a critical heat test. The heat value determined by the critical heat test depends on the energy of the CO2 laser generator 5, the amplitude of the galvanometer, and the cross-sectional dimensions of the glass, including diameter and wall thickness;

[0034] Galvanometer amplitude width: This is used to adjust the width of the heating area;

[0035] Pull force: This is the pulling force applied to the glass after it becomes soft. This pull force value can be a hard pull on the glass or a very light pull on the glass, depending on the required tip taper and tip size. The smaller the pull force value, the shorter the taper.

[0036] Speed: This is the speed at which the slider moves when the glass starts to melt. The speed setting is related to the viscosity of the glass. The higher the viscosity, the higher the speed should be set. For the same type of glass, the smaller the speed setting, the shorter the taper.

[0037] Time: When the glass is pulled, the duration of blowing cooling air to the glass and the heating plate. In the time mode, when the softened glass is pulled to the set speed, the cooling air starts to blow while pulling hard. The duration of this cooling air is determined by the time parameter.

[0038] Delay: This is another way to control the cooling time. It cannot be used at the same time as the time mode. In the delay mode, when the glass softens and reaches the set speed, it starts cooling first. The cooling time depends on the set delay value. After the delay time is reached, the pull head will start to pull hard, and the cooling air will continue to cool the glass and the heater. This mode allows you to more intuitively feel the effect of glass viscosity on forming. Specific embodiment three:

[0040] Reference Figure 1-7 When the entire laser drawing instrument body 1 is actually used, the galvanometer adjustment mechanism 6 and the reflector adjustment mechanism 9 can be set according to the structure shown in the figure in addition to the above-mentioned structure, such as the axis used for the rotation angle, etc., which can be set in combination with actual adjustment needs. At the same time, the structure of the CO2 laser generator 5 for the generation and emission of the laser can be set with reference to the structure of the existing CO2 laser generator 5.

[0041] In summary:

[0042] The microelectrode is drawn by a CO2 laser generator 5 inside the laser drawing instrument body 1, which changes the drawing of the traditional heating plate and heating wire. The CO2 laser generator 5 is easier to control parameters such as energy, amplitude width, and heat, making the electrode drawing more accurate. At the same time, through the adjustment and testing of various parameters, various types of motors can be drawn, with a long service life and no metal residue. The laser heat can be used as soon as it is turned on, and no heat residue will appear. It has high durability, low cost and consumables, and is convenient for practical use. At the same time, the utility model uses laser to draw, and the laser drawing instrument can draw quartz glass with a very high melting point, and has a wider range of applications.
