[0027] The utility model provides an ink drop observation instrument.

[0028] See also Figure 1 In one embodiment of the utility model, the ink droplet observation instrument includes a nozzle module 1, an observation module 2, a material module 3 and a frame 4; wherein the nozzle module 1 includes a nozzle 12 and a first moving mechanism 11, and the first moving mechanism 11 drives the nozzle 12 to move along a first motion trajectory; the observation module 2, the observation module 2 includes a camera component 21 and a light source component 22 arranged horizontally at intervals, and an observation space 5 is provided between the camera component 21 and the light source component 22, and the observation space 5 is used for the ink droplets ejected by the nozzle 12 to pass through; the material module 3, the material module 3 includes a stage 31 and a second moving mechanism 32, the stage 31 is used to load materials, and the second moving mechanism 32 drives the stage 31 to move along a second motion trajectory; the first moving mechanism 11 and the second moving mechanism 32 are combined to enable the nozzle 12 to perform a printing operation on the material; and the frame 4, the frame 4 is used to install the nozzle module 1, the observation module 2 and the material module 3. With such arrangement, after the observation module 2 observes the ink drop state and needs to perform printing verification, the nozzle 12 can be moved along the first motion trajectory to the position corresponding to the material module 3 by the first moving mechanism 11, and the corresponding position is the position where the first motion trajectory and the second motion silica gel intersect; and then the loading platform 31 of the material module 3 is moved along the second motion trajectory to the position of the nozzle 12 by the second moving mechanism 32, so that the nozzle 12 performs a printing operation on the material, thereby meeting the verification printing requirement. Moreover, since the verification printing requirement can be met, it is equivalent to further expanding the function of the ink drop observation instrument. In this embodiment, the first motion trajectory and the second motion trajectory are linear motions, and the first motion trajectory is formed by multiple segments of linear motion. It can be understood that the ink drop observation instrument can also perform a separate ink drop observation operation. When performing the ink drop operation, the nozzle 12 is moved into the observation space 5, so that the ink drop ejected by the nozzle 12 passes through the observation space 5, and the camera component 21 in the observation space 5 will record the relevant information of the ink drop state. The ink drop state includes the volume, shape and moving speed of the ink drop, etc. The light source assembly 22 is used to improve the clarity of the ink drop information.

[0029] Furthermore, the ink droplet observation instrument may further include a display module, which is electrically connected to the observation module 2 to visualize the state information of the ink droplets. The display module may be a computer.

[0030] In some embodiments, Figure 2The camera assembly 21 is arranged horizontally, and the camera assembly 21 includes a camera body 211 and an extended lens 212. One end of the extended lens 212 is connected to the camera body 211, and the other end of the extended lens 212 is located at the first side of the observation space 5; the light source assembly 22 is located at the second side of the observation space 5, and the first side and the second side of the observation space 5 are arranged relatively. Since the volume of the ink droplets is small, the ink droplets can be further enlarged by setting the extended lens 212, which is conducive to better observing the ink droplets and obtaining the state information of the ink droplets. The light source assembly 22 is located at the second side of the observation space 5, and the extended lens 212 is located at the first side of the observation space 5 that is arranged relatively to the second side, which is conducive to the light source assembly 22 and the extended lens 212 forming a facing position relationship, so that when the extended lens 212 shoots the ink droplets, a backlight is formed under the action of the light source assembly 22, thereby improving the clarity of the ink drop shape.

[0031] Further, in some embodiments, the light source assembly 22 includes a front light source 221 and a side light source 222, wherein the front light source 221 is located at the second side of the observation space 5 and is disposed opposite to the extended lens 212. That is, it can be understood that the front light source 221 is disposed opposite to the extended lens 212 to form a backlight effect; the side light source 222 is used for lighting, which is conducive to better observation of ink drop details.

[0032] In some embodiments, the camera assembly 21 further includes an adjustment structure 213, which is used to adjust the distance between the extended lens 212 and the observation space 5 to enhance the use flexibility of the observation module 2. Further, the adjustment structure 213 may be a horizontally arranged guide rail and guide groove, one of which is connected to the camera body 211, and the other is connected to the frame 4.

[0033] In some embodiments, an ink receiving box 6 is provided below the observation space 5, and the ink receiving box 6 is used to receive ink droplets; the ink receiving box 6 is provided with an opening, and the ink droplets enter the ink receiving box 6 through the opening. The setting of the ink box is beneficial to preventing the ink droplets from splashing and scattering, so as to maintain the cleanliness of the observation space 5 and reduce the cleaning cost.

[0034] In some embodiments, Figure 3The first moving mechanism 11 includes a slide assembly 111, and the slide assembly 111 is connected to the driving source; the slide assembly 111 includes a first slide 1111, a second slide 1112 and a third slide 1113; the nozzle module 1 also includes a first slide rail 13, and the first slide rail 13 is fixedly connected to the nozzle 12; the frame 4 includes a second slide rail 41 and a first guide plate 42 fixedly connected thereto; the first slide rail 13 is slidably connected to the first slide 1111, the first guide plate 42 is slidably connected to the second slide 1112, and the second slide rail 41 is slidably connected to the third slide 1113; the first slide 1111 and the third slide 1113 are located on opposite sides of the slide assembly 111, the first slide 1111 is arranged along the Z-axis direction, the third slide 1113 is arranged along the X-axis direction, and the second slide 1112 passes through the slide assembly 111 and is arranged along the X-axis direction. That is, the first moving mechanism 11 moves along the first slide rail 13 and the first guide plate 42 on the frame 4 on the X-axis through the first slide groove 1111 and the second slide groove 1112 of the slide groove assembly 111 to adjust the position of the nozzle 12 in the X-axis direction. In addition to playing a guiding role, the first guide plate 42 can also strengthen the support role of the first moving mechanism 11 and improve the stability of the first moving mechanism 11. The nozzle 12 moves along the first slide groove 1111 in the Z-axis direction through the first slide rail 13 to adjust the position of the nozzle 12 in the Z-axis direction. The motion trajectory of the nozzle 12 on the X-axis and Z-axis forms a first motion trajectory.

[0035] Furthermore, in some embodiments, Figure 4 and Figure 5 , the second moving mechanism 32 is located at the bottom of the stage 31, and the second moving mechanism 32 includes a fourth slide 321, which is arranged on the side of the second moving mechanism 32 facing away from the stage 31, and the fourth slide 321 is arranged along the Y-axis direction; the frame 4 is provided with a third slide rail 43, and the third slide rail 43 is slidably arranged in the fourth slide 321. That is, the second moving mechanism 32 moves along the third slide rail 43 in the Y-axis direction through the fourth slide 321 to adjust the position of the stage 31 on the Y-axis, so that the material on the stage 31 is located below the nozzle 12; in this way, the nozzle 12 can perform the verification printing operation. The nozzle 12 can form a second motion trajectory on the motion trajectory of the stage 31 on the Y-axis. It can be understood that since the stage 31 moves in one direction, when adjusting the position of the nozzle 12, the position of the nozzle 12 in the X-axis direction should be adjusted to a position that can overlap with the first motion trajectory.

[0036] Furthermore, the second moving mechanism 32 further includes a fifth slide groove 322, which is disposed on one side of the second moving mechanism 32 close to the stage 31, and is disposed along the Y-axis direction; the frame 4 further includes a second guide plate 44, both ends of which are connected to the frame 4, and the second guide plate 44 is slidably disposed in the fifth slide groove 322. The second guide plate 44 is used to improve the stability of the stage 31 in the Y-axis direction; and can be used to shield the third slide rail 43 on the frame 4 to improve the overall neatness.

[0037] In some embodiments, the material module 3 further includes a negative pressure mechanism, and the stage 31 is provided with a plurality of through holes 33, and the negative pressure mechanism forms a negative pressure area 34 on the stage 31 through the through holes 33. The negative pressure area 34 is used to adsorb materials, such as paper, plates, etc., which can improve the accuracy of printing.
