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 As shown, the object of this method is the filter cover 14. The filter cover 14 is cylindrical, and its cylindrical outer side is the glue surface 15. The glue application method includes the following steps:

[0033] a. Feeding: a glue chuck 3 and a material moving mechanism 12 are set up, and the filter cover 14 is clamped and transferred to the glue chuck 3 through the material moving mechanism 12; in step a, the material moving mechanism 12 includes a picking The material clamp 13 clamps the outer surface of the filter cover 14 and moves the filter cover 14 to a designated area. The way of gripping the filter cover 14 through the picking clamp 13 is relatively easy to realize, the structure is simple, and the moving mode is easy to design.

[0034] b. Glue dip: set the glue tank 2, fill the glue tank 2 with glue, set up a glue dip mechanism 6, through the glue mechanism 6 to dip the glue in the glue tank 2, move the glue chuck 3...

Embodiment 2

[0042] Such as Figure 4 As shown, the general content of this embodiment is the same as that of the first embodiment. The difference is that in this embodiment, the vertical cylinder 8 is fixed above 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, which has the advantage of reducing the degree of bending 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 the first embodiment. The difference is that in this embodiment, the mounting plate 9 is in a "Z" shape, and the length of the piston rod of the vertical cylinder 8 changes the mounting plate The degree of bending.

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 gluing method and a device for a medical plastic needle filter cover. Background technique [0002] A section of filter tube is connected to the general medical plastic needle. The filter tube is provided with a filter hole, and a filter cover is arranged in the filter hole. The filter cover and the filter hole are bonded by glue. [0003] Existing medical plastic needle filter cover gluing usually uses a glue stick to extend into the groove containing glue to get the glue, and then stretch the glue stick full of glue into the plastic needle filter hole with the filter membrane installed to filter Glue is applied to the inner wall of the hole, and finally the filter cover is installed on the plastic needle filter hole. As disclosed in the patent (201210183292.8), the gluing method for the plastic needle assembly of the infusion set includes the following steps: a, in...
