Description

Technical Field

[0001] This utility model relates to the field of MLCC ceramic capacitor printing technology, specifically to an MLCC ceramic capacitor printing device. Background Technology

[0002] MLCC ceramic capacitors, also known as surface mount capacitors, can be manufactured using screen printing. Nickel paste is printed onto a ceramic strip (film) through a screen, and then dried in an oven. However, some current printing equipment may produce problems such as printing stripes, ghosting, inconsistent printing angles, and printing offsets, resulting in limited printing accuracy and efficiency. In some cases, some ink may leak onto the printing platform, making it dirty.

[0003] Patent CN 212499437 U discloses a thin-film printing apparatus, including: a printing roller for printing ink onto a printing surface of a thin-film substrate; and a drying module comprising a vacuum isolation device and multiple heating rollers. The thin-film substrate enters the vacuum isolation device from an inlet end, passes through the multiple heating rollers, and then exits from an outlet end to the outside of the vacuum isolation device. The vacuum isolation device creates an environment with a pressure lower than atmospheric pressure, allowing the thin-film substrate to be heated by the heating rollers under these sub-atmospheric pressure conditions, thus drying the ink. However, this patent is not applicable to the printing of MLCC ceramic capacitors. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 6This utility model provides a technical solution: an MLCC ceramic capacitor printing equipment, comprising a blank film unwinding mechanism 1, a printing mechanism 2, a mark dot detection mechanism 3, a baking mechanism 4, and a blank film rewinding mechanism 5 arranged horizontally in sequence. The blank film unwinding mechanism 1 includes an unwinding frame 101, on which an unwinding roller 102 and a tension roller 103 are horizontally arranged. A blank film (not shown in the figure) is wound on the unwinding roller 102. The blank film has holes punched in it. A line scan detection sensor 104 is arranged above the unwinding frame 101. The printing mechanism 2 includes four support columns 201, on which a rotary lifting cylinder 202 is vertically arranged. A squeegee mounting bracket 203 is arranged on the rotary lifting cylinder 202 on the four support columns 201. A printing squeegee 204 is mounted on the squeegee mounting bracket 203. The printing squeegee 204 is positioned below... The system includes a screen mounting frame 205, on which a printing screen 206 is mounted. Below the printing screen 206, an adsorption printing platform 207 is provided, with negative pressure suction holes 208 on the printing platform 207. The Mark point detection mechanism 3 includes a detection table 301, on which a linear slide rail 302 is provided. A ceramic film adsorption moving plate 303 is slidably mounted on the linear slide rail 302. The detection table 301 is equipped with a Mark point detection camera 304 and a first servo motor 305 for driving the ceramic film adsorption moving plate 303 to slide on the linear slide rail 302. The blank film winding mechanism 5 includes a horizontally arranged winding roller 501 and a second servo motor 502 for driving the winding roller 501 to rotate. The winding roller 501 is parallel to the unwinding roller 102, and the blank film passes around the tensioning roller 103 onto the winding roller 501. The machining and installation tolerances of each component of printing mechanism 2 are controlled within 0.02mm to ensure printing accuracy.

[0022] Preferably, an electrical control unit 6 is provided on the side of the Mark point detection mechanism 3, and the electrical control unit 6 controls the operation of each part of the MLCC ceramic capacitor printing equipment.

[0023] Preferably, the unwinding roller 102 is parallel to the tensioning roller 103.

[0024] Preferably, the unwinding frame 101 is provided with a correction baffle 105, which is located beside the blank film led out from the unwinding roller 102. The correction baffle 105 restricts the horizontal position of the blank film and prevents the blank film from deviating.

[0025] Preferably, an adsorption plate 106 is provided on one end of the unwinding frame 101 near the printing mechanism 2. The adsorption plate 106 can adsorb blank film and keep it stationary when necessary.

[0026] Preferably, the scraper mounting bracket 203 is provided with a nickel paste detection sensor 209 for detecting the amount of nickel paste printed.

[0027] Preferably, the baking mechanism 4 includes multiple oven sections 401 connected end to end.

[0028] In this utility model of MLCC ceramic capacitor printing equipment, during the printing of MLCC ceramic capacitors, the blank film is led out from the unwinding roller 102, passes through the tensioning roller 103, and arrives at the adsorption printing platform 207. The negative pressure suction hole 208 adsorbs the blank film onto the adsorption printing platform 207. The ceramic film to be printed is placed on the blank film on the adsorption printing platform 207, and simultaneously adsorbed onto the blank film. The line scan detection sensor 104 detects the integrity of the blank film and the ceramic film to be printed. The rotary lifting cylinder 202 on the four support pillars 201 raises or rotates to adjust the horizontal position, horizontal angle, and height of the squeegee mounting bracket 203, ensuring that the printing squeegee 204 is in an accurate printing position relative to the ceramic film to be printed, thereby guaranteeing printing accuracy and solving the problem of... To address issues such as inconsistent printing angles and printing misalignment, nickel paste is added to the printing screen 206. A squeegee 204, driven by a corresponding motor, scrapes across the printing screen 206, transferring the nickel paste onto the ceramic film to form a chip capacitor. A first servo motor 305 drives the ceramic film adsorption moving plate 303 to slide on a linear guide rail 302. The ceramic film adsorption moving plate 303 picks up the printed ceramic film and moves it to a mark point detection camera 304 for inspection, checking the accuracy of the mark points. Then, the ceramic film adsorption moving plate 303 picks up the printed ceramic film and moves it onto a conveyor belt at the oven 301 (marked in the diagram). The conveyor belt delivers the printed ceramic film to the oven 301 for baking, allowing the nickel paste printed on the ceramic film to solidify. After one ceramic film is printed, the take-up cylinder 501 rotates to collect a blank film. A section of blank film with printing nickel paste adhering to the adsorption printing platform 207 is removed, and a clean blank film is transferred to the adsorption printing platform 207 for the next ceramic film to be printed. In this way, the blank film can prevent nickel paste from soiling the adsorption printing platform 207, and the adsorption printing platform 207 does not need to be cleaned frequently, which helps to ensure the continuity of printing and printing efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
