Embodiment 1

[0087] A trocar dispensing assembly tool, such as figure 1 shown, including:

[0088] pedestal 1;

[0089] The assembly plate 2 is connected to the upper side of the base frame 1, and its length direction is parallel to the length direction of the base frame 1;

[0090] Sleeve assembly hole 20, which is a transverse through hole opened in the assembly plate 2, arranged in parallel along the length direction of the assembly plate 2;

[0091] The needle guide block 3 is connected with the base frame 1 and is located inside the assembly plate 2 .

[0092] There are mainly the following defects in the existing cannula needle assembly process: 1), dispensing with a hand-held cannula needle, the efficiency is slow, and the dispensing effect cannot be guaranteed, and the defective rate is high; 2), The dispensing assembly tooling and dispensing equipment do not cooperate well. Although the dispensing assembly speed has been improved, the dispensing effect is still unsatisfactory; ...

Embodiment 2

[0098] A trocar dispensing assembly tooling of the present embodiment is further improved on the basis of Embodiment 1, such as figure 1 As shown, the sleeve assembly hole 20 is set obliquely to the horizontal plane; the needle guide block 3 is movably connected to the base frame 1 .

[0099] The oblique setting of the forehead in this embodiment means that the angle between the assembly hole 20 and the horizontal plane is not equal to 0°, that is, the angle between the axis of the casing assembly hole 20 and the horizontal plane is not equal to 0°, and the traditional glue dispenser points The glue end is vertically downward. When the casing and the needle are filled in the dispensing assembly tool of this embodiment, this setting makes the dispensing surface greatly increase relative to the horizontal dispensing surface of the casing and the needle, further enhancing The effect of dispensing glue.

[0100] When dispensing glue, if the glue is placed on the part where the ne...

Embodiment 3

[0106] A kind of trocar dispensing assembly tooling of the present embodiment is further improved on the basis of embodiment 2, such as Figure 5 , Figure 6 and Figure 7 As shown, it also includes a cannula limiting step 21 , which is arranged on the assembly plate 2 near the end of the needle guide block 3 to limit the movement of the cannula in the cannula assembly hole 20 .

[0107] When the casing assembly hole 20 is set obliquely, the loaded casing may slip out of the casing assembly hole 20 during the assembly process, which will affect the dispensing process. Therefore, this embodiment sets the casing limit Level 21, restricting the tendency of the casing to slide out toward the direction of the needle guide block 3, the structure of the casing limiting step 21 in this embodiment is as follows Figure 5 , Figure 6 and Figure 7 As shown, it is an angle steel structure, one side is connected to the end of the assembly plate 2, and the other side is blocked between...

Abstract

The invention discloses a casing pipe and needle dispensing assembly tool and a dispensing assembly method, and belongs to the field of workpiece assembly. The tool comprises a base frame, an assemblyplate, casing pipe assembly holes and a needle guiding block; the assembly plate is connected to the upper side of one side of the base frame; the length direction of the assembly plate is parallel with the length direction of the base frame; the casing pipe assembly holes are transverse through holes formed in the assembly plate and are arranged in parallel in the length direction of the assembly plate; the needle guiding block is connected with the base frame and is located on the inner side of the assembly plate; the casing pipe assembly holes are formed obliquely relative to the horizontal plane; the needle guiding block is connected with the base frame through telescopic rods; and one end of each telescopic rod is rotationally connected with the base frame, and the other end is fixedly connected with the needle guiding block. According to the tool and the method, casing pipes are assembled in the casing pipe assembly holes in the assembly plate in batches, needles are assembled in the casing pipes, then the dispensing operation is performed, the casing pipe and needle dispensing assembly tool cooperates with a dispensing machine, batched dispensing assembly of the casing pipes and the needles is realized, thus the dispensing assembly efficiency is greatly improved, and the dispensing effect is guaranteed.

Description

technical field [0001] The invention belongs to the field of workpiece assembly, and more specifically relates to a cannula needle dispensing assembly tool and a dispensing assembly method. Background technique [0002] In modern medicine, it is often necessary to use needles to penetrate the patient's body to achieve certain medical purposes. The needles used are usually small diameter needles. The needle body of this needle is easy to bend, and the knife edge is easily damaged. A sleeve is installed outside the needle to protect the needle body. At the same time, when the needle is used, the sleeve first touches and presses the skin, and then the needle is inserted, which greatly reduces the pain experienced by the patient. [0003] When the existing cannula is assembled, the method of dispensing is usually used to fix the needle and the cannula. Usually, the cannula is manually hand-held on the dispensing machine for dispensing. The efficiency is slow and the dispensing e...
