Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of piezoelectric injection valve equipment, and in particular to a piezoelectric injection valve positioning device. Background Art
[0002] The piezoelectric jet valve operates by maintaining a certain distance between the dispensing head and the substrate. Instantaneous high pressure forces the glue near the nozzle outlet to accelerate, causing it to separate from the nozzle, form droplets, and coat the target location. This non-contact jet dispensing valve is widely used for controlling the flow of various adhesives, such as surface adhesives, conductive silver pastes, IC packaging adhesives, underfills, sealants, and surface coatings.
[0003] The piezoelectric injection valve needs to be fixed by a positioning device during use, which makes it difficult to adjust the angle and height of the injection valve according to the situation. The adjustment and positioning process of the injection valve is very time-consuming. To this end, we propose a piezoelectric injection valve positioning device. Summary of the Invention
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a piezoelectric injection valve positioning device.
[0005] In a first aspect, the present application provides a piezoelectric injection valve positioning device, comprising:
[0006] An injection valve, wherein a hose is provided on the side of the injection valve, the hose is connected to the syringe at the lower part of the injection valve, and a positioning mechanism is provided on the side of the injection valve;
[0007] The positioning mechanism includes a column connected to the injection valve, one end of the column is clamped in the limit seat, the end of the column is connected to the handle through a rotating shaft, the top of the limit seat is connected to the connecting seat through an electric push rod, and an inner cylinder is provided on the top of the injection valve. The top of the inner cylinder is screwed with an outer cylinder, and a spring is installed inside the outer cylinder through a connecting ring.
[0008] According to the technical solution provided in the embodiment of the present application, a valve seat is provided at the bottom of the injection valve, and a limiting hole is opened on the side of the valve seat.
[0009] According to the technical solution provided in the embodiment of the present application, an annular groove is provided on the side of the column, and the column and the limit seat are fixedly connected by screws inserted into the annular groove.
[0010] According to the technical solution provided in the embodiment of the present application, the rotating shaft is rotatably connected to the limit seat through a bearing.
[0011] According to the technical solution provided in the embodiment of the present application, a threaded portion is provided on the outer side of the top of the inner cylinder.
[0012] According to the technical solution provided in the embodiment of the present application, an air pressure valve is provided on the top of the outer cylinder.
[0013] To sum up, the present technical solution specifically discloses a piezoelectric injection valve positioning device, which sets a column on the side door of the injection valve, and with the cooperation of the rotating shaft and the limit seat, the injection valve can be rotated by the handle to achieve the angle adjustment of the injection valve. After the adjustment is completed, the column and the limit seat can be locked by the action of the screw, which effectively ensures the overall stability of the injection valve during the processing. By setting an electric push rod as a connecting mechanism, the height of the limit seat can be adjusted as needed, thereby achieving the purpose of adjusting the height of the injection valve and meeting the usage requirements in different situations. By setting a accommodating mechanism composed of an inner cylinder and an outer cylinder, the height of the outer cylinder can be adjusted by rotation, so that the tightness of the spring can be adjusted. The structural design is simple and reasonable, and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example 1
[0021] Please refer to Figure 1 and Figure 2As shown, a piezoelectric injection valve positioning device includes an injection valve 1, a hose 11 is provided on the side of the injection valve 1, the hose 11 is connected to a syringe 12 at the lower part of the injection valve 1, and a positioning mechanism is provided on the side of the injection valve 1;
[0022] The positioning mechanism includes a column 13 connected to the injection valve 1, one end of the column 13 is clamped in the limit seat 14, and the end of the column 13 is connected to the handle 18 through the rotating shaft 17. By arranging the column 13 on the side door of the injection valve 1, the injection valve 1 can be rotated by the handle 18 with the cooperation of the rotating shaft 17 and the limit seat 14, thereby realizing the angle adjustment of the injection valve 1.
[0023] The top of the limit seat 14 is connected to the connecting seat 2 through an electric push rod 19. By setting the electric push rod 19 as a connecting mechanism, the height of the limit seat 14 can be adjusted according to needs, thereby achieving the purpose of adjusting the height of the injection valve 1 and meeting the usage requirements in different situations.
[0024] An inner cylinder 21 is provided at the top of the injection valve 1, and an outer cylinder 23 is screwed to the top of the inner cylinder 21. A spring 25 is installed inside the outer cylinder 23 through a connecting ring 24. Specifically, when the elasticity of the spring 25 is adjusted, the pressure of the spring on the connecting mechanism is changed, thereby achieving different usage effects. By setting a accommodating mechanism composed of the inner cylinder 21 and the outer cylinder 23, the height of the outer cylinder 23 can be adjusted by rotation, thereby adjusting the tightness of the spring 25.
[0025] Furthermore, a valve seat 27 is provided at the bottom of the injection valve 1, which effectively supports the injection valve 1. A limiting hole is provided on the side of the valve seat 27. Through the setting of the limiting hole, the valve seat 27 can be fixed to the corresponding connecting mechanism to achieve the fixing effect of the entire valve body.
[0026] Furthermore, an annular groove 15 is opened on the side of the column 13, and the column 13 and the limit seat 14 are fixedly connected by a screw 16 inserted into the annular groove 15. After the adjustment is completed, the column 13 and the limit seat 14 can be locked under the action of the screw 16, which effectively ensures the overall stability of the injection valve 1 during the processing process.
[0027] Furthermore, the rotating shaft 17 is rotatably connected to the limiting seat 14 through a bearing.
[0028] Furthermore, a threaded portion 22 is provided on the outer side of the top of the inner cylinder 21 , and an internal thread that cooperates with the threaded portion 22 is provided on the inner side of the bottom end of the outer cylinder 23 .
[0029] Furthermore, an air pressure valve 26 is provided on the top of the outer cylinder 23 , and the air pressure inside the outer cylinder 23 can be adjusted under the action of the air pressure valve 26 .
[0030] Working principle: When this piezoelectric injection valve positioning device is used, the hose 11 is connected to the glue supply mechanism, and the glue enters the syringe 12 on the lower side of the injection valve 1 through the hose 11 and is sprayed out. When the angle of the injection valve 1 needs to be adjusted, the user manually rotates the shaft 17 through the handle 18. The shaft 17 drives the injection valve 1 to rotate to a suitable angle through the column 13, and then the screw 16 is screwed in from the through hole reserved on the limit seat 14. The screw 16 is screwed into the annular groove 15 to complete the fixation of the column 13 and the limit seat 14. If the height of the injection valve needs to be adjusted, the electric push rod 19 is started by an external switch. The electric push rod 19 extends or contracts to drive the limit seat 14 to move up and down, so as to achieve the purpose of adjusting the height of the injection valve 1. With the cooperation of the above-mentioned mechanism, the angle and height of the injection valve 1 can be effectively adjusted, thereby meeting the usage effect under different needs.
