Problems solved by technology

[0004] However, since the gluing rod is directly dipped in glue and then inserted into the filter hole of the plastic needle, the larger the contact area between the dispensing rod and the glue, the greater the amount of glue absorbed, and the smaller the filter hole of the plastic needle, only a little Glue is enough, so the glue application method often leads to too much glue, and too much glue can easily flow into the filter membrane, causing the filter membrane to lose its function

Embodiment 1

[0032] Such as figure 1 , figure 2 with image 3 Shown, the object of this method is filter cover 14, and filter cover 14 is columnar, and its cylindrical outer surface is glue-coating surface 15, and this glue-coating method comprises the steps:

[0033] a. Feeding: a gluing chuck 3 and a material transfer mechanism 12 are set, and the filter cover 14 is clamped and transferred to the gluing chuck 3 by the material transfer mechanism 12; the material transfer mechanism 12 in step a includes a The material clamp 13, the material removal clamp 13 clamps the outer surface of the filter cover 14 and moves the filter cover 14 to a designated area. The method of clamping the filter cover 14 by the pick-up clip 13 is relatively easy to realize, the structure is simple, and the moving method is easy to design.

[0034]b. Glue dipping: set the glue holding tank 2, put glue in the glue holding tank 2, set a glue dipping mechanism 6, dip the glue in the glue holding tank 2 through t...

Embodiment 2

[0042] Such as Figure 4 As shown, the general content of this embodiment is the same as that of Embodiment 1, the difference is that in this embodiment, the vertical cylinder 8 is fixed on the top of the mounting plate 9, and the piston rod of the vertical cylinder 8 faces downward and the mounting plate 9 Fixed, the mounting plate 9 is in a "Z" shape, and its advantage is to reduce the bending degree of the mounting plate 9 by changing the position of the vertical cylinder 8.

Embodiment 3

[0044] Such as Figure 5 As shown, the general content of this embodiment is the same as that of Embodiment 1, the difference is that in this embodiment, the mounting plate 9 is in a “Z” shape, and the length of the mounting plate is changed by the length of the piston rod of the vertical cylinder 8. degree of curvature.

Abstract

The invention provides a glue coating method and device for a medical plastic needle filter cover, and belongs to the technical field of medical assembly equipment. The glue coating method and device for the medical plastic needle filter cover solve the technical problem that the amount of glue between a filter hole and a filter cover cannot be moderate easily in the existing glue coating process. The filter cover included in the glue coating method is columnar, and the glue coating method comprises the following steps of feeding, glue soaking and glue coating. The invention further provides the glue coating device for the medical plastic needle filter cover. According to the glue coating method and device, the principle that a glue coating chunk clamps the filter cover is utilized, glue is coated to the outer side face of the filter cover, the glue coating object is changed, the coating amount of glue keeps at the optimal state all the time through the gravity effect on glue, the situation that glue in the filter hole is excessive in the prior art is avoided, and by the glue coating method and device, the combination quality of the filter cover after glue coating and the filter hole is better.

Description

technical field [0001] The invention belongs to the technical field of medical assembly equipment, and relates to a glue coating method and a device for medical plastic needle filter caps. Background technique [0002] A section of filter tube is connected to a general medical plastic needle, and a filter hole is arranged in the filter tube, and a filter cover is arranged in the filter hole, and the filter cover and the filter hole are bonded by glue. [0003] The existing medical plastic needle filter cover is usually glued by sticking the glue rod into the groove containing the glue to get the glue, and then extending the glue rod covered with glue into the filter hole of the plastic needle with the filter membrane installed, to filter Dot glue on the inner wall of the hole, and finally install the filter cover on the filter hole of the plastic needle. As disclosed in the patent (201210183292.8), the glue application method of the plastic needle assembly of the infusion s...
