Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] The following describes an embodiment of this utility model based on its overall structure.
[0029] like Figures 1 to 5 As shown, this utility model provides a dispensing platform with a multi-channel dispensing head precise alignment adjustment structure, including a motor 12, a lead screw 13 fixedly installed inside the motor 12, a nut 15 spirally installed on the outer side of the lead screw 13, a rotating shaft 16 rotatably installed at the end of the lead screw 13, a connecting plate 17 fixedly installed on the lower end face of the nut 15, a dispensing tube 18 fixedly installed on the lower end face of the connecting plate 17, and a limiting block 14 fixedly installed on the rear end face of the nut 15. Through the motor 12 and the lead screw 13, the moving distance and speed of the nut 15 can be precisely controlled, thereby achieving precise positioning of the dispensing tube 18 in the vertical direction, meeting the requirements of precise alignment of the multi-channel dispensing head. The limiting block 14 can prevent the nut 15 from moving excessively, playing a protective role and ensuring adjustment accuracy.
[0030] In this embodiment, a block 10 is fixedly provided on the inner side of the motor 12. A square groove 11 is opened inside the block 10, and a limiting groove 19 is opened inside the block 10. Through the square groove 11 and the limiting groove 19, the movement range of related components can be limited, making the device more reliable during operation.
[0031] A distributor 9 is fixedly mounted on the upper end face of block 10, a fixing block 8 is fixedly mounted on the upper end face of distributor 9, and a slider 6 is fixedly mounted on the upper end face of fixing block 8. Through fixing block 8 and slider 6, it is possible to move and adjust distributor 9 in the horizontal direction, which further improves the ability of distributor head to be accurately aligned.
[0032] A connecting post 4 is fixedly provided on the outer side of slider 6. An electric slide rail 2 5 is provided inside the connecting post 4, and slider 6 is inside the electric slide rail 2 5. Through the electric slide rail 2 5 and slider 6, the moving distance and speed of the dispenser 9 can be precisely controlled to meet the precise alignment requirements of different dispensing needs.
[0033] Slider 2 7 is fixedly installed on both the left and right sides of the connecting column 4. Support column 2 is fixedly installed on the outside of slider 2 7. Through slider 2 7 and connecting column 4, the connecting column 4 and the liquid dispenser 9 can move and adjust in a wider range in the horizontal direction, which further improves the accurate positioning capability of the liquid dispenser head.
[0034] The support column 2 has an electric slide rail 3 inside, and the slider 7 is inside the electric slide rail 3. The liquid distribution platform body 1 is fixedly installed on the lower end face of the support column 2. Through the electric slide rail 3, the liquid distribution head can be precisely adjusted in both horizontal and vertical directions, realizing a wide adjustment range of the multi-channel liquid distribution head and meeting the liquid distribution needs in different experimental or production processes.
[0035] Working principle and process of the dispensing platform with multi-channel dispensing head precise alignment adjustment structure:
[0036] When the position of the dispensing head needs to be adjusted in the horizontal X-axis direction, the electric slide rail 25 starts working, and the slider 16 is fixed on the fixed block 8. The fixed block 8 is connected to the dispensing device 9. The electric slide rail 25 drives the slider 16 to slide inside it, thereby moving the dispensing device 9, the fixed block 8, and the connected lower components in the horizontal X-axis direction, realizing the position adjustment of the dispensing head in the X-axis direction. If the position adjustment of the dispensing head in the horizontal Y-axis direction is required, the electric slide rail 13 starts running, and the slider 27 is fixed on the left and right sides of the connecting column 4. The connecting column 4 is connected to other components. The electric slide rail 3 drives the slider 7 to slide inside it, thereby moving the connecting column 4 and the dispensing device 9 and motor 12 connected to it in the horizontal Y-axis direction, completing the position adjustment of the dispensing head in the Y-axis direction. Through the joint adjustment of the horizontal X-axis and Y-axis, the dispensing head can be accurately moved to the required horizontal position. After the horizontal position adjustment is completed, if it is necessary to adjust the vertical position of the dispensing head, the motor 12 starts to work, and the lead screw 13 inside the motor 12 starts to move under the drive of the motor. Rotation occurs because a nut 15 is helically mounted on the outer side of the lead screw 13. The rotation of the lead screw 13 causes the nut 15 to move linearly along the lead screw 13. A limiting block 14 is fixedly mounted on the rear end face of the nut 15. The limiting block 14 slides within a limiting groove 19 opened inside the block 10, serving to limit and guide movement, ensuring that the nut 15 can only move linearly along the lead screw 13 and will not rotate. The lower end face of the nut 15 is fixedly connected to the dispensing pipe 18 via a connecting plate 17. Therefore, the linear movement of the nut 15 will cause the connecting plate 17 and the dispensing pipe 18 to move linearly. The screw 13 moves vertically, and the end of the screw 13 is equipped with a rotating shaft 16 to ensure the stability of the screw 13's rotation. By rotating the motor 12 in both directions, the dispensing tube 18 can be raised or lowered to achieve precise adjustment of the vertical position of the dispensing head. When the dispensing head moves to the precise target position, the dispenser 9 starts to work, accurately dispensing the liquid through the dispensing tube 18 to the designated position. The dispenser 9 can control the amount and speed of dispensing according to the preset program and parameters, thus playing the role of a dispensing platform with a multi-channel dispensing head precise alignment adjustment structure.
