[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1-4 The present invention provides a technical solution: a filter duct bonding device, comprising a chassis 10, a filter fixing groove 20, a thin cylinder 30, a duct fixing groove 40, a foot switch 50, a pneumatic solenoid valve 60, an air pressure regulating valve 70 and a stainless steel rubber bowl 80;

[0030] The filter fixing groove 20 and the thin cylinder 30 are both mounted on the chassis 10 by bolts. When in use, the filter component can be placed in the filter fixing groove 20. The foot switch 50 and the pneumatic solenoid valve 60 are connected by a pipe, and the pneumatic solenoid valve 60 and the thin cylinder 30 are connected by a pipe. The output end of the thin cylinder 30 is fixedly mounted with a support plate 31 by bolts, and the support plate 31 is fixedly mounted with a catheter fixing groove 40 for positioning the catheter.

[0031] When the catheter needs to be connected to the filter component, the filter component is placed in the filter fixing groove 20, the catheter dipped in adhesive is placed in the catheter fixing groove 40, and the end of the catheter dipped in adhesive is aligned with the filter head of the filter component. Then, the foot switch 50 is pressed, and the thin cylinder 30 is driven to work through the pneumatic solenoid valve 60. The thin cylinder 30 pushes the catheter fixing groove 40 forward, thereby pushing the end of the catheter dipped in adhesive close to the filter head of the filter component, so that the end of the catheter dipped in adhesive is bonded to the filter head of the filter component, completing the bonding process.

[0032] Among them, the pneumatic solenoid valve 60 and the air pressure regulating valve 70 are connected by a pipeline. The air pressure regulating valve 70 can adjust the air pressure supplied to the thin cylinder 30, thereby adjusting the power of the thin cylinder 30 to push the support plate 31 and the catheter fixing groove 40.

[0033] Among them, the filter fixing groove 20 includes a base plate 21 and a groove body 22 for placing the filter component. The groove body 22 is arranged on the base plate 21. The groove body 22 and the base plate 21 are an integrated structure. When in use, the filter component is placed in the groove body 22, and the filter component is limited by the groove body 22.

[0034] Among them, a limiting groove 24 for limiting the filter head of the filter component is opened on one side of the top of the trough body 22. After the filter component is placed inside the trough body 22, the filter head of the filter component is stuck in the limiting groove 24. The position of the filter head of the filter component is limited by the limiting groove 24, and the filter head is placed to prevent it from being offset.

[0035] Among them, a cutting surface 25 is provided on one side of the bottom plate 21 and the groove body 22 close to the limiting groove 24. The side surface of the bottom plate 21 and the groove body 22 is set to a flat cutting surface 25. In this way, when the thin cylinder 30 pushes the catheter fixing groove 40 to move forward, it is ensured that the end of the catheter fixing groove 40 can be in close contact with the cutting surface 25, preventing the presence of a gap at the contact position of the catheter fixing groove 40 and the groove body 22, thereby improving the accuracy of bonding the catheter to the filter head of the filter component.

[0036] There are two grooves 23 symmetrically formed on the top of the tank body 22 . The two grooves 23 are respectively located on both sides of the limiting groove 24 . The grooves 23 facilitate the removal of the filter component in the tank body 22 .

[0037] Among them, an arc-shaped groove for placing the catheter is formed on the catheter fixing groove 40, and the axis of the arc-shaped groove is on the same straight line as the axis of the limiting groove 24. In this way, when the thin cylinder 30 pushes the catheter fixing groove 40 and the catheter to move forward, the end of the catheter can be accurately bonded to the filter head in the limiting groove 24.

[0038] Among them, a convex positioning point 81 is provided at the bottom of the inner wall of the stainless steel rubber bowl 80. The stainless steel rubber bowl 80 can store the adhesive for bonding the catheter. When the catheter needs to be bonded to the filter head of the filter, the adhesive is first injected into the stainless steel rubber bowl 80, and then one end of the catheter is inserted into the stainless steel rubber bowl 80, and the end of the catheter is aligned with the convex positioning point 81. The end of the catheter is put on the convex positioning point 81, so that the junction between the catheter and the convex positioning point 81 is dipped in glue, and then the excess adhesive on the outer wall of the catheter is adsorbed on the sponge, and then the next step of the catheter bonding process is carried out.

[0039] Example 2

[0040] See also Figure 1-4 The present invention provides a technical solution: a method for bonding a filter conduit, the bonding method comprising the following steps:

[0041] Step 1: Place the filter component in the filter fixing groove 20, and make the filter head of the filter component be located in the limiting groove 24, and limit the position of the filter head by the limiting groove 24;

[0042] Step 2: Select a tube to be bonded to the filter component, then add adhesive to the stainless steel rubber bowl 80. Next, insert one end of the tube into the stainless steel rubber bowl 80 and align the end of the tube with the convex positioning point 81. Slide the end of the tube over the convex positioning point 81 so that the junction of the tube and the convex positioning point 81 is dipped in glue. Then, absorb the excess adhesive on the outer wall of the tube onto the sponge.

[0043] Step 3: Place the catheter with one end dipped in adhesive on the catheter fixing groove 40, with the end of the catheter dipped in adhesive pointing toward the filter fixing groove 20;

[0044] Step 4: Align the filter head of the filter component with the end of the catheter dipped in adhesive;

[0045] Step 5: Depress the foot switch 50, and then drive the thin cylinder 30 to work through the pneumatic solenoid valve 60, and push the catheter fixing groove 40 forward through the thin cylinder 30, thereby pushing the end of the catheter dipped in adhesive to approach the filter head of the filter component, so that the end of the catheter dipped in adhesive is bonded to the filter head of the filter component, completing the bonding process.
