[0036] In order to prevent the glass slide 4 from losing stability and falling off from the adsorption component 3 during the process of printing cell tissue on the adsorption component 3, Figures 1 to 5As shown, an adsorption device 100 includes a support seat 1, an adsorption component 3, and a buffer component 2, wherein the adsorption component 3 is installed on the support seat 1, and the adsorption component 3 has an adsorption surface 35; the buffer component 2 includes an elastic member 22 and a support block 21, the support block 21 is installed on the first end of the elastic member 22, and the second end of the elastic member 22 is installed on the support seat 1, and the support block 21 has a contact surface 212; wherein the support block 21 and the adsorption component 3 are arranged on the same side of the support seat 1, and the adsorption surface 35 and the contact surface 212 are staggered or located on the same plane. One end of the adsorption component 3 is used to adsorb the glass slide 4, and the other end of the adsorption component 3 is used to connect the vacuum device; when in use, vacuum is drawn in the adsorption component 3, so that the adsorption component 3 is under negative pressure, and the adsorption surface 35 of the adsorption component 3 generates suction and acts on the glass slide 4; when the glass slide 4 on the adsorption component 3 is used to print cell tissue, since the support block 21 and the adsorption component 3 are arranged on the same side of the support base 1, the adsorption surface 35 and the abutting surface 212 are located on the same plane, and the abutting surface 212 of the support block 21 supports the glass slide 4 The support increases the stability of the glass slide 4 on the adsorption component 3. When the glass slide 4 is subjected to the pressure of the printing tool, the glass slide 4 transmits the pressure to the support block 21, and the support block 21 applies the pressure to the elastic member 22. After the elastic member 22 is squeezed, a reverse force is generated to counteract the pressure on the support block 21. The elastic member 22 absorbs most of the kinetic energy of the support block 21 and reduces the speed at which the glass slide 4 moves toward the support seat 1, thereby improving the stability of the glass slide 4 on the adsorption component 3 and preventing the glass slide 4 from falling off the adsorption component 3 when printing cells. When the adsorption component 3 is elastic, the adsorption surface 35 and the abutment surface 212 can be staggered.

[0037] In order to improve the stability of the support block 21 during movement. Figures 1 to 5As shown, the support seat 1 has a mounting hole 11 that runs from one side of the support seat 1 to the other side, and the buffer assembly 2 also has a guide column 23. The first end of the guide column 23 passes through the mounting hole 11 and is mounted on the support block 21. The second end of the guide column 23 abuts against the support seat 1, and the guide column 23 and the support seat 1 are slidably matched; the elastic member 22 is sleeved on the outside of the guide column 23, and the two ends of the elastic member 22 abut against the support block 21 and the support seat 1 respectively. When the support block 21 is subjected to the pressure of the glass slide 4, the support block 21 will drive the guide column 23 to slide and match with the support seat 1, and the guide column 23 moves in the mounting hole 11. The mounting hole 11 limits the moving direction of the guide column 23, and also improves the stability of the support block 21 when it moves. Moreover, when the support block 21 moves, it will squeeze the elastic member 22. The reaction force generated by the elastic member 22 after being squeezed acts on the support seat 1 and the support block 21 respectively. When the support seat 1 is fixed, the reaction force generated by the elastic member 22 directly acts on the support block 21, offsetting the pressure of the support block 21, thereby achieving a buffering effect on the glass slide 4, thereby further improving the stability of the glass slide 4 on the support block 21, reducing the impact force of the adsorption component 3 on the glass slide 4, and avoiding instability of the glass slide 4.

[0038] In order to limit the position of the support block 21 on the support base 1 and facilitate the installation of the support block 21 and the guide column 23. Figure 3 and Figure 4 As shown, the support block 21 has a connection hole, the guide column 23 has a guide rod 232 and a stop block 231, the first end of the guide rod 232 is threadedly connected to the connection hole, the stop block 231 is installed at the second end of the guide rod 232, the outer diameter of the stop block 231 is larger than the outer diameter of the guide rod 232 and the aperture of the mounting hole 11, and the end of the stop block 231 away from the guide rod 232 has a notch. When the pressure on the glass slide 4 disappears, the reaction force generated by the elastic member 22 drives the support block 21 to move to the initial position, and the stop block 231 moves to abut against the support seat 1, thereby limiting the position of the support block 21 on the support seat 1. When installing the support block 21, one end of the guide rod 232 passes through the mounting hole 11, the elastic member 22 is sleeved on the outside of the guide rod 232, one end of the guide rod 232 extends into the connecting hole of the support block 21, a tool is inserted into the slot of the limit block 231, and the guide rod 232 is driven to rotate, so that the guide rod 232 is threadedly connected to the support block 21 and fixed.

[0039] In order to further improve the stability of the elastic member 22. Figure 3As shown, the support block 21 has a limiting groove 211, which is connected to the connecting hole, and the outer diameter of the limiting groove 211 is larger than the outer diameter of the connecting hole, and the elastic member 22 is at least partially disposed in the limiting groove 211. Since the elastic member 22 is sleeved outside the guide column 23, the guide column 23 limits the extension direction of the elastic member 22, and the elastic member 22 is at least partially in the limiting groove 211, and the inner wall of the limiting groove 211 is used to abut against the outer wall of the elastic member 22. When the support block 21 squeezes the elastic member 22, the inner wall of the limiting groove 211 further limits the moving direction of the elastic member 22 and improves the stability of the elastic member 22.

[0040] In order to further improve the stability of the glass slide 4 on the adsorption assembly 3. Figure 3 As shown, there are four guide posts 23, the number of mounting holes 11 corresponds to the number of guide posts 23, and the four guide posts 23 are arranged at the four vertices of the support block 21. Four guide posts 23 are respectively arranged at the four vertices of the support block 21, and each guide post 23 is sleeved with an elastic member 22. When the support block 21 is subjected to the pressure of the glass slide 4, the four vertices of the support block 21 squeeze the four elastic members 22 at the same time, and the reaction force generated by the four elastic members 22 offsets the pressure on the glass slide 4 as much as possible. Even if it cannot be completely offset, it will further reduce the moving distance and moving speed of the glass slide 4 after being subjected to pressure, thereby improving the stability of the glass slide 4 on the adsorption component 3.

[0041] In order to achieve the adsorption of the glass slide 4 by the adsorption component 3. Figure 1 , Figure 2 , Figure 5 As shown, the adsorption assembly 3 includes a first suction cup 31 and a first joint 33. The first joint 33 is installed on the first side 13 of the support base 1, and the first suction cup 31 is installed on the second side 14 of the support base 1. The first suction cup 31 and the first joint 33 are arranged opposite to each other. The first side 13 and the second side 14 of the support base 1 are used to support and fix the first joint 33 and the first suction cup 31 respectively, so as to improve the stability of the adsorption assembly 3 on the support base 1. A first air channel 311 is formed in the first suction cup 31, and a second air channel 331 is formed in the first joint 33. The adsorption surface of the first suction cup 31 has an adsorption port, and the adsorption port, the first air channel 311, and the second air channel 331 are connected in sequence. The first joint 33 is used to connect the vacuum equipment. After the vacuum equipment is started, the air in the second air channel 331 and the first air channel 311 will be extracted. When the first suction cup 31 is against the glass slide 4, the first suction cup 31 is in a negative pressure state, and the adsorption port of the first suction cup 31 adsorbs the glass slide 4.

[0042] In order to improve the adsorption efficiency of the adsorption component 3. Figure 5As shown, the support base 1 has a third air channel 12, the second air channel 331 of the first joint 33 is connected to the first end of the third air channel 12, the first air channel 311 of the first suction cup 31 is connected to the second end of the third air channel 12, and the first air channel 311, the third air channel 12, and the second air channel 331 are on the same straight line. A third air channel 12 is opened in the support base 1, so that the first air channel 311 and the second air channel 331 are respectively located at the two ends of the third air channel 12, and are all on the same straight line, so as to avoid the channel of the adsorption component 3 from being bent. When vacuuming, the gas in the straight air channel is more easily and quickly discharged, so that the first suction cup 31 quickly becomes negative pressure, and the adsorption efficiency of the adsorption component 3 is improved.

[0043] In order to further improve the stability of the glass slide 4 on the adsorption assembly 3. Figure 1 , Figure 2 , Figure 5 As shown, the adsorption assembly 3 further includes a second joint 34 and a second suction cup 32. The second joint 34 is disposed on the first side surface 13 of the support base 1, the second suction cup 32 is disposed on the second side surface 14 of the support base 1, and the support block 21 is disposed between the first suction cup 31 and the second suction cup 32. The first suction cup 31 and the second suction cup 32 are respectively used to adsorb two different adsorption points on the glass slide 4, thereby increasing the adsorption area between the adsorption assembly 3 and the glass slide 4, thereby improving the stability of the glass slide 4 on the adsorption assembly 3; and the support block 21 is disposed between the first suction cup 31 and the second suction cup 32, so that the support block 21 can support the middle section of the glass slide 4, and the two ends of the glass slide 4 are fixed by the first suction cup 31 and the second suction cup 32, and the support block 21 is used to absorb the pressure generated by the middle section of the glass slide 4 when printing cell tissue.

[0044] In order to further improve the stability of the glass slide 4 on the adsorption assembly 3. Figure 5 As shown, both the first suction cup 31 and the second suction cup 32 are retractable, and the retracting direction of the first suction cup 31 and the second suction cup 32 is consistent with the retracting direction of the elastic member 22. When the glass slide 4 on the first suction cup 31 and the second suction cup 32 is subjected to pressure, the glass slide 4 transmits the force to the first suction cup 31 and the second suction cup 32, and the first suction cup 31 and the second suction cup 32 absorb part of the force, thereby reducing the moving speed of the glass slide 4 on the first suction cup 31 and the second suction cup 32 and improving the stability of the glass slide 4.

[0045] In addition, at least part of the first suction cup 31 or the second suction cup 32 is made of elastic material. The first suction cup 31 and the second suction cup 32 made of elastic material can quickly return to their original state when in use, ensuring that the suction cup and the adsorbed object always maintain close contact and provide stable adsorption force.
