Description

TECHNICAL FIELD

[0001] The utility model relates to a split charging technical field, concretely is a solar silver paste bottle split charging mechanism. BACKGROUND

[0002] Solar silver paste is a kind of material playing a key role in the process of solar cell manufacturing, and the main component is silver powder and organic carrier. Silver powder is the main body of the conductive function of silver paste, and its particle size, shape and distribution will have a significant impact on the performance of silver paste. Generally speaking, the particle size of silver powder is small, which can increase the number of silver powder particles in a certain volume to some extent, which helps to improve the conductivity of silver paste. The organic carrier mainly plays the role of dispersing silver powder and adjusting viscosity, so that the silver paste can better adapt to the process requirements such as printing, and it can also volatilize in the sintering process.

[0003] Under the prior art, the slurry coming out of the three-roll mill is flowed into the plastic bottle through a funnel with an opening, and the slurry is bottled and split charged. However, since the outlet of the three-roll mill is very wide and the opening of the plastic bottle is very small, part of the slurry may fall outside the funnel during the process of the slurry flowing from the wide outlet to the small bottle opening, resulting in waste of materials. Moreover, the cost of silver paste is relatively high, and the price of silver powder is expensive, so the waste of slurry will increase the production cost. Therefore, we propose a solar silver paste bottle split charging mechanism to solve the above problems. UTILITY MODEL CONTENTS

[0022] 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.

[0023] Example: Figures 1-5 As shown, this utility model provides a solar silver paste bottling and dispensing mechanism, including a funnel 1, an assembly cylinder 2 at the bottom of the funnel 1, a control component 3 inside the assembly cylinder 2, and dispensing bottles 4 at the bottom of the assembly cylinder 2. A connecting plate 201 is fixedly connected to one end of the assembly cylinder 2 near the funnel 1, and the top of the connecting plate 201 is fixedly connected to the funnel 1. A feeding window 202 penetrating through the surface of the connecting plate 201 is opened, and the funnel 1 communicates with the assembly cylinder 2 through the feeding window 202. The control component 3 includes multiple arc-shaped seats 301, which are evenly distributed around the axis of the assembly cylinder 2. The seat 301 is placed inside the assembly cylinder 2. The top of the arc-shaped seat 301 is slidably connected to the connecting plate 201. Multiple arc-shaped seats 301 are arranged in a cylindrical structure. The gap between the arc-shaped seat 301 and the assembly cylinder 2 forms a movable chamber 303. When the arc-shaped seat 301 is slid outward by the external force of the dispensing bottle 4, the opening in the middle of the arc-shaped seat 301 will open, forming a relatively regular discharge channel through which the slurry can pass. At this time, the solar silver paste flowing into the assembly cylinder 2 from the funnel 1 will flow into the dispensing bottle 4 being connected in an orderly manner through this middle opening, thereby starting the dispensing process.

[0024] Further, the mobile chamber 303 is provided with a sealing ring 304, which is made of flexible rubber material. The outer ring wall of the sealing ring 304 is fixedly connected with the inner wall of the assembly cylinder 2, the inner ring wall of the sealing ring 304 is in contact with the arc-shaped seat 301, the sealing ring 304 is filled in the gap between adjacent arc-shaped seats 301, and the sealing ring 304 is arranged at one end of the assembly cylinder 2 close to the sub-packaging bottle 4. The middle part surrounded by the arc-shaped seats 301 originally has an opening. When the arc-shaped seat 301 is not subjected to external force and slides outward, the sealing ring 304 is tightly filled in the gap between adjacent arc-shaped seats 301, which not only prevents the gap between adjacent arc-shaped seats 301 from leaking the slurry, but also prevents the slurry in the assembly cylinder 2 from flowing out of the opening in the middle part surrounded by the arc-shaped seats 301, because the opening is surrounded by the sealing structure formed by the sealing ring 304 and the arc-shaped seat 301, thereby ensuring the sealing of the assembly cylinder 2.

[0025] Further, the arc-shaped seats 301 are provided with a spiral groove 302 at one side close to the axis of the assembly cylinder 2. The opening at the bottom of the spiral groove 302 is larger than the opening at the top of the spiral groove 302. The sub-packaging bottle 4 is fixedly connected with a threaded opening 401 at the bottle opening. The sub-packaging bottle 4 is fixed with the arc-shaped seats 301 through the threaded opening 401. The arc-shaped seat 301 is provided with a mounting groove 305 at one side close to the assembly cylinder 2. The inner wall of the assembly cylinder 2 is provided with a plurality of uniformly distributed assembly grooves 308. The reset spring 307 is arranged between the assembly groove 308 and the mounting groove 305. The connecting cylinder 306 and the fixed cylinder 309 are respectively sleeved at both ends of the reset spring 307. The end of the fixed cylinder 309 away from the reset spring 307 is fixedly connected with the inner cavity bottom of the assembly groove 308. The end of the connecting cylinder 306 away from the reset spring 307 is fixedly connected with the inner cavity bottom of the mounting groove 305. When the solar silver paste is prepared for sub-packaging, the threaded opening 401 at the bottle opening of the sub-packaging bottle 4 is aligned with the inclined spiral groove 302 of the arc-shaped seat 301, and then the sub-packaging bottle 4 is rotated. Since the spiral groove 302 is inclined, as the sub-packaging bottle 4 is continuously screwed in, an outward force is applied to the arc-shaped seat 301, which promotes the arc-shaped seat 301 to slide outward along the inner wall of the assembly cylinder 2. In this process, the top of the arc-shaped seat 301 is slidingly connected with the connecting disc 201 to provide guidance and limiting for sliding. At the same time, the reset spring 307 between the assembly groove 308 of the inner wall of the assembly cylinder 2 and the mounting groove 305 of the arc-shaped seat 301 is stretched for subsequent work. When the sub-packaging work is completed, the sub-packaging bottle 4 is rotated down from the arc-shaped seat 301. Under the action of the retracting force of the reset spring 307, the arc-shaped seat 301 slides inward along the inner wall of the assembly cylinder 2 and gradually returns to the initial position as the external force disappears. With the reset of the arc-shaped seat 301, the sealing ring 304 again tightly fills the gap between adjacent arc-shaped seats 301, completely closes the opening in the middle part surrounded by the arc-shaped seats 301, and prevents the remaining slurry in the assembly cylinder 2 from leaking from the opening or the gap between the arc-shaped seats 301, thereby restoring the good sealing state and preparing for the next sub-packaging operation.

[0026] Through such a design, the solar silver paste can be precisely discharged from the opening in the middle of the arc-shaped seat 301 into the sub-packaging bottle 4, avoiding the problems of uneven discharge and spilling caused by random flow from the gap, ensuring the accuracy and stability of sub-packaging. The sealing ring 304 plays a key sealing role in the entire process, whether it is in a static state before sub-packaging, during sub-packaging, or after sub-packaging, it can effectively seal the gap between the arc-shaped seats 301 and the opening in the middle of the arc-shaped seat 301. This reliable sealing mechanism greatly reduces the risk of paste leakage, not only ensures the neatness of the sub-packaging operation, avoids material waste and environmental pollution caused by paste spilling, but also ensures that the paste can flow into the sub-packaging bottle 4 through the expected channel every time, improving the quality and efficiency of sub-packaging. Moreover, the multiple arc-shaped seats 301 and the sub-packaging bottle 4 are matched by the inclined spiral groove 302, which can still adapt to different specifications and shapes of the sub-packaging bottle 4, meet the needs of various actual sub-packaging scenes, and improve the versatility and practicality of the entire sub-packaging mechanism.

[0027] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
