Description

Technical Field

[0001] This utility model belongs to the field of graphene sheet manufacturing technology, specifically relating to a self-cleaning device for scrapers. Background Technology

[0002] Graphene sheets are typically used as conductive components, requiring the application of conductive adhesive. Currently, conductive adhesives for graphene are applied using roller coating. Conductive adhesive is an adhesive that has certain conductivity after curing or drying. It is usually composed of a base resin and conductive fillers (such as copper powder and nickel powder). During the coating process, a scraper is used to evenly coat the conductive adhesive onto the surface of the graphene sheet.

[0003] However, currently, after the conductive adhesive is applied, residual conductive adhesive easily adheres to the surface of the scraper, which usually requires manual cleaning. Cleaning the residual conductive adhesive is quite tedious and affects the subsequent scraping of conductive adhesive by the scraper, greatly reducing the coating efficiency of conductive adhesive. To address this, we propose a scraper self-cleaning device. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-3 This utility model provides a technical solution: a self-cleaning device for a scraper, wherein the crossbeam 2 is the main supporting structure, a connecting frame 1 is provided on the back of the crossbeam 2, a positioning frame 3 is provided at the bottom of the connecting frame 1, and a scraping mechanism 4 for cleaning the adhesive on the surface of the conductive adhesive scraper 5 is provided on the positioning frame 3.

[0028] The scraping mechanism 4 includes a positioning seat 41, on which a positioning blade 42 corresponding to the conductive adhesive scraper 5 is provided. A scraper plate 43 is provided on one side of the inner wall of the positioning blade 42, and an electric heating plate 44 is embedded on the inner wall of the positioning blade 42 on one side of the scraper plate 43. The positioning frame 3 is also provided with a drive structure for controlling the movement of the positioning seat 41.

[0029] The drive structure includes a ball screw 33, which is rotatably mounted in a mounting groove. The mounting groove is located on one side surface of the positioning frame 3. A ball screw pair 31 is also mounted on the ball screw 33. The ball screw pair 31 is connected to the positioning seat 41. By rotating the ball screw 33, the moving position of the ball screw pair 31 can be controlled, thereby controlling the movement of the positioning seat 41.

[0030] When the conductive adhesive scraper 5 moves to the cleaning station, the positioning seat 41 can be moved by the transmission of the ball screw 33. At the same time, the electric heating plate 44 on the positioning seat 41 heats the surface of the conductive adhesive scraper 5 and melts the conductive adhesive. The melted adhesive can be scraped off by the movement of the scraper plate 43.

[0031] Furthermore, one end of the ball screw 33 is connected to the drive shaft of the drive motor 32, which is mounted on one side surface of the positioning frame 3 and can control the rotation direction of the ball screw 33.

[0032] Furthermore, a collection box 45 is also provided on the positioning seat 41 below the positioning blade 42. When the positioning seat 41 moves, the scraped adhesive can drip into the collection box 45, and the residual adhesive is collected.

[0033] Of course, the collection box 45 in this application can be a detachable structure to facilitate the cleaning of the colloid inside the collection box 45.

[0034] Furthermore, the conductive adhesive scraper 5 is disposed on one side of the upright 6, the upright 6 is disposed on one side of the bottom of the crossbeam 2, and a translation mechanism 8 for driving the upright 6 to move laterally is also disposed on one side of the crossbeam 2. Specifically, the translation mechanism 8 can be a screw and nut drive structure or an electric push rod telescopic drive structure. The translation mechanism 8 can control the movement of the upright 6, and the movement of the upright 6 drives the conductive adhesive scraper 5 to move laterally, and uniformly coat the conductive adhesive on the surface of the graphene sheet, and uniformly scrape the conductive adhesive, and can move the conductive adhesive to the cleaning station.

[0035] Please see Figures 4-6 A limiting rod 7 is also provided on one side surface of the upright frame 6. The limiting rod 7 corresponds to the limiting groove 11. The limiting groove 11 is provided on one side surface of the connecting frame 1, which can limit the movement position of the upright frame 6, so that the upright frame 6 can move accurately to the cleaning station. A limit switch 12 is also provided on one side surface inside the limiting groove 11. The limit switch 12 is connected to the input end of the drive motor 32, which can automatically control the positioning seat 41 to move and clean the adhesive adhering to the conductive adhesive scraper.

[0036] When the conductive adhesive scraper 5 moves to the cleaning station, the limit rod 7 moves into the limit groove 11 and contacts the limit switch 12, thereby automatically controlling the drive motor 32 to run, realizing the automatic cleaning of the adhesive on the conductive adhesive scraper 5.

[0037] Furthermore, a fixing frame 10 is also provided on one side of the crossbeam 2, and a conductive adhesive dispensing head 9 is provided inside the fixing frame 10, which can apply conductive adhesive to the surface of the graphene sheet.

[0038] Furthermore, the conductive adhesive dispensing head 9 is connected to an external adhesive delivery device via a pipe, enabling real-time delivery of the conductive adhesive.

[0039] In this application, the limit switch 12 is also connected to the electric heating plate 44, which can automatically control the operation of the electric heating plate 44.

[0040] Working principle and usage process of this utility model:

[0041] First, a robotic arm places the graphene sheet onto a processing table located below the conductive adhesive dispensing head 9. Then, conductive adhesive is delivered to the surface of the graphene sheet via the dispensing head 9. A translation mechanism 8 moves the support frame 6, which in turn moves the conductive adhesive scraper 5. The scraper 5 spreads the accumulated conductive adhesive evenly across the graphene sheet surface. After coating, the support frame 6 moves the limit rod 7. When the limit rod 7 enters the limit groove 11, it contacts the limit switch 12. At this point, the conductive adhesive scraper 5... The device moves to the cleaning station, and the limit switch 12 controls the drive motor 32 to run. The drive motor 32 drives the ball screw 33 to rotate, and the ball screw pair 31 drives the positioning seat 41 to move. The positioning seat 41 drives the positioning blade 42 to move. The positioning blade 42 moves along the blade direction of the conductive adhesive scraper 5. During the movement, the electric heating plate 44 heats the conductive adhesive scraper 5 and melts the adhered adhesive. After melting, as the positioning seat 41 moves, the scraper 43 moves accordingly and quickly scrapes off the adhesive, realizing the rapid cleaning of the conductive adhesive scraper 5.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
