Description

Technical Field

[0001] This invention belongs to the technical field of conductive pastes, and in particular, relates to a conductive paste delivery system. Background Technology

[0002] Conductive paste is a multiphase composite fluid material composed of conductive functional phase, binder phase, solvent, dispersant and other additives mixed in a specific ratio. Its core function is to form a conductive layer or conductive structure (such as electrodes, circuits, interconnect grids) on the surface of a substrate through processes such as coating, printing, and spraying, so as to realize electronic signal transmission, current collection or electrochemical reaction interface construction. It is widely used in photovoltaic cells, new energy vehicle power batteries, electronic components (MLCC, sensors), flexible electronics, smart wearable devices and other fields.

[0003] The shortcomings of existing technology: In the processing and production of the aforementioned conductive slurry, a conveying system is often used to transport the processed conductive slurry from the upstream mixing equipment to the downstream application equipment. However, in actual production, when the slurry generation rate of the upstream mixing equipment consistently exceeds the consumption rate of the downstream equipment, the excess conductive slurry cannot be consumed by the downstream in a timely manner. It must be temporarily stored in a buffer tank located between the upstream mixing equipment and the downstream application equipment. A low-speed rotating agitator is used to reduce high-speed shearing and break up large particle agglomerations, preventing the conductive slurry from settling and agglomerating. Typically, the agitator includes a drive source, a screw, and a stirring element. The drive source drives the screw to rotate, which in turn drives the stirring shaft to rotate synchronously, mixing the conductive slurry in the buffer tank. However, because there are large particles in the conductive slurry, these particles easily adhere to the threads on the screw, clogging the thread grooves and making it difficult for the stirring shaft to move. This can lead to the stirring shaft jamming, affecting its mixing effect and causing the conductive slurry to separate due to settling, thus impacting its performance and processing quality. Summary of the Invention

[0009] Furthermore, each of the support plates is provided with a scraper on the side away from the drive plate, one side of the scraper is connected to the side of the support plate away from the screw, and the other side of the scraper abuts against the inner wall of the buffer tank.

[0010] Furthermore, the bottom of the screw is provided with a fixing plate for supporting the first sealing ring. The bottom of the fixing plate is fixed to the bottom wall of the buffer tank, the top of the fixing plate is rotatably connected to the bottom of the screw, and the fixing plate is fixed to the bottom of the first sealing ring.

[0011] Furthermore, the driving device includes: A drive motor, the fixed end of which is connected to the support frame, and the output end of which is coaxially connected to the top of the screw; The controller is mounted on the support frame and is connected to an eddy current displacement sensor.

[0015] Compared with the prior art, one or more technical solutions in the embodiments of the present invention have at least one of the following beneficial effects: An embodiment of the present invention provides a conductive slurry conveying system. Through a support frame, drive plate, sealing mechanism, and connecting mechanism installed inside a buffer tank, when the screw rotates, the drive plate rotates, causing the agitator to move synchronously. The drive plate moves axially along the screw, causing the third sealing ring to move synchronously with the drive plate. Through the connecting mechanism, the inner walls of the sealing mechanisms on both sides of the drive plate always cover the threaded grooves on the screw, thus preventing large particles in the conductive slurry from contacting and clogging the threaded grooves. This allows the drive plate and the agitator to operate normally, enabling the agitator to agitate the conductive slurry in the buffer tank and improve the processing quality of the conductive slurry.

Furthermore, in one or more embodiments, particular features, structures, or characteristics may be combined in any suitable manner.

[0025] Please refer to the following: Figures 1 to 5 The present invention will now describe a conductive slurry conveying system according to an embodiment of the present invention. The conductive slurry conveying system provided by the embodiment of the present invention includes an inlet pipe 71, a buffer tank 1, and an outlet pipe 72 disposed along one side of the conductive slurry conveying direction. The inlet pipe 71 is connected to an upstream mixing device, and the outlet pipe 72 is connected to a downstream mixing device.

[0026] The conductive slurry conveying system also includes an opening and closing element 8 and an online agitator 73 located on the discharge pipe 72. The opening and closing element 8 includes a drive pump 81 and a valve 82. One end of the drive pump 81 is connected to the buffer tank 1, and the other end of the drive pump 81 is connected to the discharge pipe 72. The valve 82 is located at the end of the discharge pipe 72 away from the drive pump 81 and is connected to the discharge pipe 72. The online agitator 73 is located between the drive pump 81 and the valve 82, and is located inside the discharge pipe 72. Specifically, the online agitator 73 is selected from the IKA MHD2000 series online mixer to agitate the conductive slurry in the discharge pipe 72, so that the conductive slurry is less likely to separate into layers in the discharge pipe 72 and affect the processing quality of the conductive slurry.

[0027] The conductive slurry conveying system also includes a support frame 31, a drive device 21, a screw 22, a fixing plate 13, a drive plate 32, a mixing element 11, and a scraper 12. The drive device 21 includes a drive motor 211 and a controller 212, and the mixing element 11 includes a mixing shaft. The bottom of the support frame 31 is fixed to the top of the buffer tank 1, and the drive motor 211 is fixed to the top of the support frame 31. The output shaft of the drive motor 211 passes through the support frame 31 and is coaxially fixed to the screw 22. The top of the vertically arranged screw 22 is rotatably connected to the bottom of the support frame 31, and the bottom of the screw 22 extends into the buffer tank 1 and is rotatably connected to the bottom wall of the buffer tank 1. The horizontally arranged fixing plate 13 is located at the bottom of the screw 22, and the fixing plate 13 is rotatably connected to the screw 22 through a second bearing 92. The bottom of the fixing plate 13 is detachably connected to the bottom wall of the buffer tank 1 by bolts. A horizontally positioned drive plate 32 is sleeved on and threadedly connected to the screw 22. The width of the drive plate 32 exceeds the width of the support frame 31. Support plates 33 are installed on both sides of the drive plate 32. One side of each support plate 33 is fixed to the side wall of the drive plate 32, and the other side of the support plate 33 is fixed to the side wall of the scraper 12. The side of the scraper 12 away from the support plate 33 abuts against the inner side wall of the buffer tank 1. There are two sets of stirring components 11, and the two sets of stirring components 11 correspond one-to-one with the two support plates 33. Each set of stirring components 11 includes several stirring shafts located at the bottom of the support plate 33. The top of the vertically positioned stirring shaft is fixed to the bottom of the support plate 33. The controller 212 is located at the top of the support frame 31 and is connected to an eddy current displacement sensor 213 located at the bottom of the support frame 31. The eddy current displacement sensor 213 is used to detect the distance between the support frame 31 and the drive plate 32. Since the width of the drive plate 32 is greater than the width of the support frame 31, and the vertical projection of the detection port of the eddy current displacement sensor 213 is always located on the upper surface of the drive plate 32 when the drive plate 32 rotates, it is convenient for the eddy current displacement sensor 213 to detect the distance between the support frame 31 and the drive plate 32. Specifically, the controller 212 includes an L298N model H-bridge driver chip, and the eddy current displacement sensor 213 includes a Keyence EX-050 series. When the distance between the support frame 31 and the drive plate 32 exceeds the set range, the controller 212 is activated, thereby enabling the drive motor 211 to rotate in both directions.

[0028] The operator starts the drive motor 211. The output shaft of the drive motor 211 rotates, causing the screw 22 to rotate synchronously. The rotation of the screw 22 causes the drive plate 32 to rotate and rise synchronously, which in turn causes the support plate 33, the stirring shaft, and the scraper 12 to move synchronously, stirring the conductive slurry in the buffer tank 1. This prevents the conductive slurry from separating due to settling or uneven density, thus ensuring uniform mixing of the particles and improving the processing quality of the conductive slurry. The stirring shaft and scraper 12 expand the stirring range within the buffer tank 1, preventing dead zones in the conductive slurry and ensuring uniform mixing. In addition, the controller 212 enables the drive motor 211 to rotate in both directions, causing the drive plate 32, stirring shaft and scraper 12 to move back and forth along the axial direction of the screw 22, further improving the stirring performance. Furthermore, when the scraper 12 rotates, it abuts against the inner wall of the buffer tank 1 to scrape off the conductive slurry on the inner wall of the buffer tank 1, making it less likely for the conductive slurry to adhere to the inner wall of the buffer tank 1, making it easier for staff to clean the inner wall of the buffer tank 1, and also reducing the waste of conductive slurry and saving resources.

[0029] To prevent the threaded grooves on the screw 22 from being blocked by particles in the conductive slurry and affecting one end of the drive plate 32, the conductive slurry conveying system also includes a sealing mechanism 4 and a connecting mechanism 5 disposed at the top and bottom of the drive plate 32. The sealing mechanism 4 includes a first sealing ring 41, a second sealing ring 42 and a third sealing ring 43, and the connecting mechanism 5 includes a guide block 51, a baffle 52 and a sealing layer 53. The first sealing ring 41 is located at the top or bottom of the screw 22. The first sealing ring 41 is fixed to the bottom of the support frame 31 or to the top of the fixing block, and the first sealing ring 41 covers the top or bottom of the screw 22. The second sealing ring 42 is located on the side of the first sealing ring 41 near the drive plate 32, and the inner wall of the second sealing ring 42 is rotatably connected to the side wall of the screw 22. The outer wall of the second sealing ring 42 is slidably connected to the inner wall of the first sealing ring 41. The third sealing ring 43 is located on the side of the second sealing ring 42 near the drive plate 32. The inner wall of the third sealing ring 43 is rotatably connected to the side wall of the screw 22. The outer wall of the third sealing ring 43 is slidably connected to the inner wall of the second sealing ring 42. The third sealing ring 43 is rotatably connected to the drive plate 32 through the first bearing 91. Meanwhile, guide grooves 61 are vertically formed on the inner sidewalls of the first sealing ring 41 and the second sealing ring 42. One side of the guide block 51 is slidably connected to the sidewall of the guide groove 61, and the other side of the guide block 51 is fixed to the third sealing ring 43 or the second sealing ring 42 respectively. The sidewall of the horizontally arranged baffle 52 is fixed to the sidewall of the guide groove 61. The baffle 52 is used to abut against the guide block 51, so that the guide block 51 is not prone to excessive lifting and lowering, which would cause the guide block 51 to detach from the guide groove 61. The sealing layer 53 is located on both sides of the baffle 52 and the baffle 52 is bonded to it. The sidewall of the sealing layer 53 abuts against the sidewall of the guide groove 61. The sealing layer 53 is made of rubber material.

[0030] The screw 22 is located within the conductive slurry. When the drive motor 211 starts, the screw 22 rotates synchronously, causing the drive plate 32 to move synchronously. Through the first bearing 91 at the top or bottom of the drive plate 32, the two third sealing rings 43 move synchronously under the drive of the drive plate 32. Through the connecting mechanism 5, the two second sealing rings 42 move synchronously. Through the first sealing ring 41, the second sealing ring 42, and the third sealing ring 43, the threaded groove on the screw 22 never comes into contact with the conductive slurry, thus making it difficult for particles in the conductive slurry to be transmitted to the threaded groove on the screw 22 and affect the lifting and lowering of the drive block. This allows the screw 22 to drive the drive plate 32 to move. In addition, the guide block 51 and the guide groove 61 guide the second sealing rings 42 and the third sealing rings 43, so that the second sealing rings 42 and the third sealing rings 43 only move vertically and not rotate along the rotation axis of the screw 22, reducing wear between the third sealing rings 43 and the second sealing rings 42 and the screw 22, and extending the service life of the screw 22.

[0031] The working principle of this invention is as follows: After the worker transfers the conductive slurry from the upstream mixing equipment to the buffer tank 1, the worker starts the drive motor 211. The output shaft of the drive motor 211 rotates, causing the screw 22 to rotate synchronously, which in turn causes the drive plate 32 to move synchronously. Through the eddy current displacement sensor 213 and the controller 212, the drive motor 211 is controlled to rotate in both directions, thereby causing the screw 22 to rotate in both directions. When the screw 22 rotates, to prevent particles in the conductive slurry from adhering to the threaded grooves on the screw 22, the third sealing ring 43 is connected to the drive plate 32 through the sealing mechanism 4 at the top and bottom of the drive plate 32 via the first bearing 91. This allows the two third sealing rings 43 to rise and fall synchronously under the drive of the drive plate 32 while the drive plate 32 rotates and rises and falls. Through the guide block 51 and the guide groove 61, the two third sealing rings 43 and the two second sealing rings 42 rise and fall in the vertical direction. Through the baffle 52 and the guide block 51, the third sealing rings 43 are not easily contacted by the second sealing rings 42. The second sealing ring 42 disengages, and the second sealing ring 42 is not easily disengaged from the first sealing ring 41. This ensures that the drive plate 32, the third sealing ring 43, the second sealing ring 42, and the first sealing ring 41 always enclose the screw 22. As a result, large particles in the conductive slurry are not easily transmitted to the thread groove of the screw 22, and thus the rotation of the drive plate 32 is not easily affected by clogging the thread groove on the screw 22. This allows the agitator 11 to operate normally. Furthermore, the agitator 11 helps to prevent the conductive slurry in the buffer tank 1 from stratifying due to settling, thereby affecting the processing quality of the conductive slurry.

[0032] In addition, the scraper 12 expands the mixing range and improves the fluidity of the conductive slurry in the buffer tank 1, making it less likely for the conductive slurry in the buffer tank 1 to be affected by standing. On the other hand, the scraper 12 abuts against the inner wall of the buffer tank 1, scraping away the conductive slurry on the inner wall of the buffer tank 1. The online agitator 73 in the discharge pipe 72 improves the mixing uniformity of the conductive slurry in the discharge pipe 72, making it less likely for the conductive slurry in the discharge pipe 72 to separate due to standing, thereby improving the processing quality of the conductive slurry in the buffer tank 1 and the discharge pipe 72.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
