Abstract
Description
A silver paste coating device Technical Field
[0001] This utility model relates to the field of coating equipment technology, and in particular to a silver paste coating device. Background Technology
[0002] In high-tech industries such as electronics and photovoltaics, silver paste is a key material with wide applications and is of paramount importance. However, silver paste has extremely low reactivity, and the interaction between the internal silver particles is weak, making it difficult to flow and disperse spontaneously. This characteristic presents many challenges in the processing and use of silver paste, especially in the coating process.
[0003] The high viscosity and high yield stress of silver paste result in poor flowability, making it difficult to achieve uniform, continuous, and precise thickness coating using traditional methods. Traditional coating methods, such as brushing, spraying, or roller coating, often struggle to control the amount and uniformity of the silver paste applied, leading to inconsistent coating thickness and unstable coating quality. This not only affects product performance but also increases production costs and processing difficulty.
[0004] Therefore, there is a need to provide a silver paste coating apparatus. Summary of the Invention
[0005] In order to overcome the shortcomings of silver paste, such as poor fluidity due to its high viscosity and high yield stress, making it difficult to achieve uniform coating, this utility model provides a silver paste coating device.
[0006] A silver paste coating device includes a connecting frame, a storage frame, a second motor, a second mounting housing, a second pulley assembly, and a coating roller. The connecting frame has a U-shaped design. The upper part of the connecting frame is equipped with a storage frame. The coating roller is rotatably mounted in the upper part of the storage frame. The left end of the coating roller extends outward and passes through the storage frame and the left side of the connecting frame. The second motor is mounted on the left side of the connecting frame through the second mounting housing. The second pulley assembly is located between the left end of the coating roller and the output end of the second motor. The device also includes a supply assembly, which is located in the lower part of the storage frame.
[0007] Furthermore, it is particularly preferred that the supply assembly includes a motor, a mounting housing, a pulley assembly, and a feeding roller. The motor is mounted on the lower left side of the connecting frame via the mounting housing, and the feeding roller is laterally rotatably connected to the lower part of the storage frame. The left end of the feeding roller is connected to the output shaft of the motor via the pulley assembly.
[0008] In addition, it is particularly preferred that the device also includes adjustment ports, with adjustment ports provided on both the left and right sides of the connecting frame. The adjustment ports are located at both ends of the feeding roller and are fixed to the feeding roller by screws.
[0009] Furthermore, it is particularly preferred that the storage frame has a U-shaped design.
[0010] Furthermore, it is particularly preferred that the mounting housing 2 can block the output end of the motor 2.

Detailed Implementation
[0019] 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.
[0020] Example: A silver paste coating device, as shown in Figures 1-4, includes a connecting frame 1, a storage frame 2, a motor 3, a mounting housing 31, a pulley assembly 4, a feeding roller 5, an adjusting port 51, a second motor 6, a second mounting housing 61, a second pulley assembly 7, and a coating roller 8. The connecting frame 1 has a U-shaped design, and a U-shaped storage frame 2 is connected to the upper part of the connecting frame 1. The storage frame 2 is used to store silver paste material. The mounting housing 31 is connected to the lower left side of the connecting frame 1, and the motor 3 is mounted on the lower left side of the mounting housing 31. The mounting housing 31 can discharge the silver paste material. The output end of motor 3 is obstructed. A feeding roller 5 is laterally rotatably connected to the lower part of the storage frame 2. The storage frame 2 has a U-shaped design to facilitate the storage and supply of silver paste to the feeding roller 5. The surface of the feeding roller 5 is equipped with diamond-shaped blades to aid in stirring the silver paste. The left end of the feeding roller 5 extends outward and passes through the left side of the connecting frame 1. A pulley assembly 4 is connected between the left end of the feeding roller 5 and the output shaft of motor 3. The pulley assembly 4 consists of two pulleys and a flat belt. The two pulleys are respectively connected to the left end of the feeding roller 5 and the output end of motor 3, while the flat belt... The feed roller 5 is rotated by driving the pulley assembly 4 via the output shaft of motor 3, which is mounted on two pulleys. Adjustment ports 51 are provided on both the left and right sides of the connecting frame 1, located at both ends of the feed roller 5 and fixed to it with screws. A mounting shell 61 is connected to the upper left side of the connecting frame 1. Motor 6 is mounted on the left side of the mounting shell 61. The mounting shell 61 can cover the output end of motor 6, helping to reduce the possibility of dust, debris, etc., entering the motor 6. The storage frame 2 is located in the upper inner part... A coating roller 8 is connected to the horizontal rotation. The left end of the coating roller 8 extends outward and passes through the storage frame 2 and the left side of the connecting frame 1. A pulley assembly 7 is connected between the left end of the coating roller 8 and the output end of the motor 6. The pulley assembly 7 also consists of two pulleys and a flat belt. The two pulleys are respectively connected to the left end of the coating roller 8 and the output shaft of the motor 6. The flat belt is sleeved on the two pulleys. The output shaft of the motor 6 drives the pulley assembly 7 to drive the coating roller 8 to rotate, thereby controlling the coating of silver paste on the product.
[0021] When using the silver paste coating device, first check whether the storage box 2 is filled with an appropriate amount of silver paste material. Next, confirm that the power connections of motor 3 and motor 6 are secure, and that mounting housing 31 and mounting housing 61 properly cover their respective motor output terminals to ensure safety.
[0022] Next, turn on the power to motor 3, and motor 3 will immediately begin working. The output shaft of motor 3 drives the feed roller 5 to rotate via pulley assembly 4. The feed roller 5, with its unique diamond-shaped design, effectively agitates and evenly delivers the silver paste from the storage frame 2 to the contact area of the coating roller 8. At this time, the gap in the silver paste delivery path between the feed roller 5 and the coating roller 8 can be finely adjusted as needed by adjusting the screw on the adjusting port 51, thereby indirectly controlling the coating thickness.
[0023] Then, the power to motor 6 is turned on, and motor 6 begins to work. The output shaft of motor 6 drives the coating roller 8 to rotate via pulley assembly 7. Before starting motor 6, the product to be coated should be placed in a suitable position under the coating roller 8 to ensure that the coating roller 8 can evenly contact and coat the surface of the product when rotating. The continuous rotation of the feed roller 5 ensures a stable supply of silver paste from the storage box 2 to the coating roller 8.
[0024] The speeds of motors 3 and 6 can be flexibly adjusted as needed to precisely control the silver paste supply and coating speed, meeting different coating requirements. During the coating process, the remaining amount of silver paste and the coating quality should be checked regularly to ensure the consistency and uniformity of the coating effect.
[0025] After coating is completed, first turn off the power to motor 3 and motor 6 to ensure safe shutdown. Then, carefully clean the residual silver paste from storage box 2, feed roller 5 and coating roller 8 to keep the device clean, extend its service life, and prepare it for the next use.
[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
