Aiming at the defects of the prior art, the invention aims to provide a structure and a method for mounting a glue injection end of a capillary array.
In order to achieve the purpose, the invention adopts the following technical scheme:
a structure for mounting a glue injection end of a capillary array comprises the glue injection end of the capillary array, a hand wheel and a spindle body, wherein the glue injection end of the capillary array sequentially penetrates through center holes of the hand wheel and the spindle body and then is connected with a glue injection pump; the outer wall of the glue injection end of the capillary array is provided with a protrusion, the inner wall of the central hole of the hand wheel is provided with a boss, and the boss is provided with a guide groove through which the protrusion can pass; the capillary array glue injection end can axially rotate in the central hole of the hand wheel.
Furthermore, a mounting hole is formed in the glue injection pump, an internal thread is formed in the inner surface of the rear end of the mounting hole, and an external thread is formed on the outer surface of the front end of the hand wheel; capillary array injecting glue end passes the centre bore of hand wheel and spindle in proper order after and when being connected with the injecting glue pump, capillary array injecting glue end, spindle are located completely in the mounting hole, the front end of hand wheel stretch into in the mounting hole and with mounting hole threaded connection.
Further, the boss is the annular, circumference is provided with a plurality of bulges on the outer wall of capillary array injecting glue end, circumference is provided with a plurality of guide ways on the boss, one-to-one between each bulge and each guide way.
The invention also provides a use method of the capillary array glue injection end mounting structure, which comprises the following specific processes:
firstly, the glue injection end of the capillary array penetrates through a central hole of a hand wheel, the protrusion and the guide groove are aligned, the protrusion penetrates from one side of the boss to the other side of the boss, then the glue injection end of the capillary array is rotated until the protrusion and the guide groove are staggered, the protrusion and the boss are abutted, and the protrusion cannot pass through the boss; enabling the glue injection end of the capillary array to penetrate through the central hole of the spindle body, and finally plugging the glue injection end into the mounting hole of the glue injection pump; the hand wheel is fixed with a mounting hole of the glue injection pump through threaded connection; in the glue injection process, when the glue injection pressure is too high to extrude the glue injection end of the capillary array, the protrusion and the boss form spacing, so that the condition that the glue injection end of the capillary array moves outwards cannot occur.
The invention has the beneficial effects that: according to the invention, the boss and the protrusion are added to effectively limit the glue injection end of the capillary array, so that the precision assembly and friction among materials are not depended, the material and processing requirements of each component are greatly reduced, the production cost is reduced, and the damage to the capillary array caused by the outward movement of the glue injection end of the capillary array under the glue injection pressure during glue injection can be effectively avoided.

Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed implementation and the specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
Example 1
The embodiment provides a capillary array glue injection end mounting structure, as shown in fig. 1, which includes a capillary array glue injection end 1, a hand wheel 2 and a spindle 3, wherein the capillary array glue injection end 1 sequentially penetrates through center holes of the hand wheel 2 and the spindle 3 and then is connected with a glue injection pump 100; as shown in fig. 2 and 3, a protrusion 11 is arranged on the outer wall of the capillary array glue injection end 1, a boss 21 is arranged on the inner wall of the central hole of the hand wheel 2, and a guide groove 22 for the protrusion 11 to pass through is arranged on the boss 21; the capillary array glue injection end 1 can axially rotate in a central hole of the hand wheel 2.
Further, be equipped with mounting hole 101 in the glue injection pump 100, the rear end internal surface of mounting hole 101 is equipped with the internal thread, the front end surface of hand wheel 2 is equipped with the external screw thread, capillary array injecting glue end 1, spindle 3 are located completely in mounting hole 101, the front end of hand wheel 2 stretch into in the mounting hole 101 and with mounting hole 101 threaded connection.
Further, boss 21 is the annular, circumference is provided with a plurality of projections 11 on the outer wall of capillary array injecting glue end 1, circumference is provided with a plurality of guide slots 22 on the boss 21, and each projection 11 and each guide slot 22 between the one-to-one correspondence.
Example 2
The embodiment provides a method for using the capillary array glue injection end mounting structure as described in embodiment 1, and the specific process is as follows:
firstly, the capillary array glue injection end 1 penetrates through a center hole of a hand wheel 2 and enables the protrusion 11 and the guide groove 22 to be aligned, the protrusion 11 penetrates through the other side of the boss 21 from one side of the boss 21, then the capillary array glue injection end 1 is rotated to enable the protrusion 11 and the guide groove 22 to be staggered, the protrusion 11 and the boss 21 are abutted, and at the moment, the protrusion 11 cannot pass through the boss 21. Then the glue injection end 1 of the capillary array penetrates through the central hole of the spindle body and is finally plugged into the mounting hole 101 of the glue injection pump 100, as shown in fig. 4; the hand wheel is fixed with a mounting hole of the glue injection pump through threaded connection, and the hand wheel is shown in figure 5 after the hand wheel is mounted; in the glue injection process, the glue injection pressure is as shown in fig. 6, when the glue injection end of the capillary array is extruded due to overlarge glue injection pressure, the capillary array glue injection end does not move outwards due to the fact that the protrusion and the boss form limiting, and the capillary array is protected.
