Description

Technical Field

[0001] The utility model relates to the technical field of engineering monitoring, and more specifically to a flexible conductive adhesive coating device. Background Art

[0002] In the field of geological engineering and geological disaster monitoring, accurate deformation monitoring is crucial for early warning and disaster prevention. With the advancement of science and technology, traditional monitoring technologies have been gradually replaced by advanced monitoring systems based on flexible electronics. These systems usually rely on flexible sensors attached to geological structures to monitor deformation in real time. Flexible conductive adhesive plays an important role in this because it not only needs to transmit electrical signals, but also needs to adapt to irregular changes in terrain without breaking or falling off.

[0003] However, there are several problems with the existing flexible conductive adhesive coating technology. First, manual coating is inefficient and it is difficult to ensure the uniformity of the adhesive layer, which directly affects the performance and reliability of the sensor. Secondly, due to the complex and changeable geological environment, the coated conductive adhesive layer must have good adhesion and the ability to adapt to deformation, but the existing coating technology often cannot meet these requirements. In addition, the formula and coating process of the conductive adhesive need to be customized for different monitoring environments and targets, which puts higher flexibility requirements on the coating device.

[0004] After searching, in terms of coating technology, automation and precision control have become research hotspots in recent years. For example, Chinese patent publication number: CN219816891U discloses a conductive adhesive coating device, which can achieve high efficiency and high repeatability. However, this type of equipment is not suitable for field geological monitoring, has poor flexibility, and the equipment itself is made of rigid materials and cannot adapt to the irregular deformation of the object to be tested.

[0005] Therefore, how to provide a flexible conductive adhesive coating device with a simple structure and easy use is a problem that those skilled in the art need to solve urgently. Utility Model Content

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Embodiment 1:

[0044] See attached Figure 1 To Attachment Figure 4 The embodiment of the utility model discloses a flexible conductive adhesive coating device, including a glue injection mold frame 1 and a coating push roller 2 used in conjunction with each other;

[0045] The glue injection mold frame 1 is a rectangular frame, and a group of inner side walls opposite to each other of the glue injection mold frame 1 have symmetrically arranged stepped convex beams 12, the bottom surface of the stepped convex beams 12 is flush with the bottom surface of the glue injection mold frame 1; a wire groove 13 is provided on the bottom surface of any frame beam 11 of the glue injection mold frame 1, and the wire groove 13 connects the inner side and the outer side of the glue injection mold frame 1;

[0046] The coating push roller 2 includes a push rod 21 and a coating roller 22 fixed at one end of the push rod 21 . The coating roller 22 is used for reciprocating between the two stepped convex beams 12 .

[0047] In order to further optimize the above technical solution, the glue injection mold frame 1 and the coating push roller 2 are both made of resin or rubber materials. In this embodiment, the glue injection mold frame 1 and the coating push roller 2 are both printed using 3D printing technology.

[0048] In this embodiment, the cross section of the wire groove 13 is semicircular.

[0049] In this embodiment, the number of the wire grooves 13 is two.

[0050] In order to further optimize the above technical solution, the diameter of the coating roller 22 is greater than the height of the stepped convex beam 12 and less than the height of the frame beam 11 .

[0051] In order to further optimize the above technical solution, the end of the push rod 21 is fixed to the middle of the coating roller 22 .

[0052] The device provided in this embodiment is more focused on use on pipelines. The outer surface of the pipeline has a certain curvature. The printed and formed glue injection mold frame 1 not only has a certain strength, but also has a certain toughness. When the flexible conductive glue is coated on the pipeline, the glue injection mold frame 1 can fit the curvature of the pipeline. The wire groove 13 is located at the bottom of the frame beam 11 and has two holes, which serve as the contact points between the flexible conductive glue and the wire. In addition to effectively making the glue injection mold frame 1 fit the pipe wall, it can also protect the wire and serve as a glue overflow hole so that the overflowed glue wraps the wire. Specifically, when in use, place the glue injection mold frame 1 at the position to be tested, apply a certain pressure to make it fit tightly with the surface to be tested, and inject the flexible conductive glue. Hold the upper end of the push rod 21, apply a certain pressure, and roll the flexible conductive glue back and forth to make it extend and fit on the pipeline.

[0053] The specific usage includes the following steps:

[0054] Step 1: The bottom surface of the injection mold frame 1, with the side of the wire groove 13, is tightly attached to the surface of the object to be tested;

[0055] Step 2: Inject the flexible conductive glue into the hollow space between the two stepped convex beams 12;

[0056] Step 3: Insert the wires from the wire grooves 13 respectively, and then use the push rod 21 to roll the flexible conductive adhesive back and forth to extend it between the stepped convex beams 12. After multiple rolling, the flexible conductive adhesive can be closely attached to the surface of the object;

[0057] Step 4: Use a scraper to scrape off excess flexible conductive glue, and then use the push rod 21 to roll back and forth to make it smooth.

[0058] Embodiment 2:

[0059] This embodiment is further improved on the basis of the embodiment 1 so as to realize the integration of the structure.

[0060] See attached Figure 5 To Attachment Figure 8 , and also includes a clamping frame 3, which includes a rectangular top frame 31 and four vertical rods 32 fixed at the four corners of the rectangular top frame 31; positioning grooves 14 are opened at the four corners of the top surface of the injection mold frame 1, and the four vertical rods 32 are respectively inserted into the four positioning grooves 14.

[0061] In order to further optimize the above technical solution, the pressing frame 3 is made of hard material. In this embodiment, the pressing frame 3 can be made of metal, wood or hard plastic material.

[0062] In order to further optimize the above technical solution, a slide groove 311 is opened on the inner side of the two beams corresponding to the rectangular top frame 31 and the two stepped convex beams 12, a slide rod 33 is slidably connected between the two slide grooves 311, and the push rod 21 is connected to the slide rod 33.

[0063] In order to further optimize the above technical solution, a long hole 211 is opened between the two side walls of the push rod 21 , and the slide rod 33 passes through the long hole 211 .

[0064] The method of use of this embodiment is similar to that of embodiment 1, except that: the injection mold frame 1 does not need to be pressed manually, but is pressed by a pressing frame 3 , so that the operator only needs to press the pressing frame 3 to operate.

[0065] Due to the design of the long hole 211, when injecting glue into the hollow space between the two stepped convex beams 12, the push rod 21 can be lifted, and when rolling coating is required, the push rod 21 can be put down to drive the push rod 21 to move. Other usages of this embodiment are consistent with those of embodiment 1 and will not be described here.

[0066] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

[0067] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
