Description

Technical Field

[0001] The utility model belongs to the technical field of battery manufacturing, and particularly relates to a vacuum conveying mechanism. Background Art

[0002] Electrodes are a key component of batteries for storing and releasing electrical energy. They are typically manufactured by evenly coating the surface of a foil with a slurry, followed by drying, rolling, and slitting. Currently, during battery production, a belt mechanism is commonly used to transport the electrodes. This is a type of conveying equipment used in specific industrial environments. It primarily operates based on the principle of vacuum adsorption, using vacuum suction to secure the electrodes. This reduces friction and collisions during transport, lowering the risk of damage and ensuring continuity and accuracy during transfer.

[0003] In the related technology, the belt mechanism includes a machine, on which a vacuum part for sucking air is provided, and a vacuum cavity is formed inside the machine. The vacuum part sucks the air in the vacuum cavity to form a negative pressure environment. A vacuum port is provided on the surface of the machine, and the vacuum port is connected to the vacuum cavity; a belt for adsorbing and transmitting the electrode is rotatably provided on the machine, and adsorption holes are provided on the belt, and the adsorption holes are corresponding to the vacuum port. When the vacuum part is evacuated, the belt adsorbs and fixes the electrode through the adsorption holes to realize the transmission of the electrode.

[0004] However, when the belt mechanism adsorbs and transfers electrodes of different sizes or electrodes with different conveying speeds, it is unable to quickly adjust the vacuum degree on the belt surface, which affects the stability of the electrode transfer process. Utility Model Content

[0005] In order to solve the shortcomings of the existing technology, the utility model provides a vacuum transmission mechanism, which adjusts the gas flow at the suction port through a vacuum flow control component to adjust the vacuum degree in the air regulating pipe. The belt quickly adjusts the vacuum degree to adapt to the adsorption and fixed transmission of electrodes of different sizes or different transmission speeds, which is beneficial to improving the stability of the electrode transmission process.

[0006] The technical effects to be achieved by the present invention are achieved through the following technical aspects:

[0007] In the first aspect, the utility model provides a vacuum conveying mechanism, including a vacuum table, which is provided with a vacuum chamber for forming a negative pressure environment. The vacuum table is provided with a vacuum hole opposite to the belt; an air regulating pipe for gas circulation is provided in the vacuum chamber, one end of the air regulating pipe is connected to several of the vacuum holes, and the other end of the air regulating pipe is provided with an air suction port connected to the vacuum chamber; wherein the air regulating pipe is provided with a vacuum flow control component at the air suction port, and the vacuum flow control component controls the gas flow at the air suction port by adjusting the opening size of the air suction port.

[0008] In some implementations, a plurality of the air conditioning ducts are provided, and the plurality of the air conditioning ducts are distributed along the transmission direction of the belt.

[0009] In some implementations, the air regulating pipe is a funnel-shaped pipe body, and the air suction port is located at the narrow end of the air regulating pipe.

[0010] In some implementations, the air conditioning duct is arranged at an angle relative to a conveying direction of the belt.

[0011] In some implementations, the vacuum flow control component includes: a flap located at the air suction port and rotatably connected to the air regulating pipe; and a valve connected to the flap and driving the flap to flip in the air suction port to open or close the air suction port.

[0012] In some implementations, a seal is provided between the belt and the vacuum table for maintaining a vacuum degree at the vacuum hole.

[0013] In some implementations, the plurality of vacuum holes are arranged in a plurality of rows along the transmission direction of the belt, and the sealing member is disposed between the vacuum holes in two adjacent rows.

[0014] In some implementations, the seal is a sealing strip, and an outer wall of the sealing strip is in contact with the surface of the belt.

[0015] In some implementations, a dust removal assembly is provided on one side of the vacuum table, and the dust removal assembly includes a brush roller for cleaning the belt, and the bristles of the brush roller are in contact with the surface of the belt.

[0016] In some implementations, the dust removal assembly further includes: a mounting seat, on which the brush roller is disposed; and dust shields, disposed on both sides of the brush roller along the rotation direction to block dust falling from the brush roller, wherein the dust shields are disposed on the mounting seat.

[0017] In summary, the present invention has at least the following advantages:

[0018] The vacuum transmission mechanism provided by the utility model is such that when the vacuum chamber is evacuated, one end of the air regulating pipe is connected to the vacuum chamber via the air suction port, and the other end is connected to the vacuum hole. The gas at the vacuum hole can be sucked to the outside of the vacuum table through the air regulating pipe, the air suction port and the vacuum chamber. The vacuum table forms a negative pressure environment at the vacuum hole to adsorb the electrode.

[0019] When the vacuum flow control component adjusts the air suction port to increase it, the amount of gas sucked by the air regulating pipe through the air suction port increases. The increase in the amount of gas sucked in the air regulating pipe increases the vacuum degree in the air regulating pipe. The air regulating pipe is connected to the vacuum hole, and the vacuum degree at the vacuum hole also increases accordingly. The adsorption force of the belt at the vacuum hole increases, which is suitable for transmitting electrodes with larger size or faster conveying speed; conversely, when the vacuum flow control component adjusts the air suction port to decrease it, the gas flow sucked by the air regulating pipe through the air suction port decreases, the vacuum degree in the air regulating pipe decreases, the air regulating pipe is connected to the vacuum hole, and the vacuum degree at the vacuum hole decreases accordingly. The adsorption force of the belt at the vacuum hole decreases, which is suitable for transmitting electrodes with smaller size or slower conveying speed.

[0020] The vacuum transmission mechanism can regulate the gas flow rate of the air regulating pipe through the suction port by simply controlling the vacuum flow control part to adjust the size of the suction port. The vacuum degree at the vacuum hole can be adjusted quickly and accurately according to the different sizes and transmission speeds of the electrode, so that the adsorption force of the belt on the electrode is more reasonable, thereby realizing efficient and stable transmission of the electrode.

[0036] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Please see the attached Figure 1-3 The vacuum transmission mechanism of the present invention includes a vacuum table 1, an air regulating pipe 2 is provided in the vacuum table 1, a vacuum flow control component 22 for adjusting the vacuum flow is provided on the air regulating pipe 2, a belt 3 for transmitting the electrode is provided on the vacuum table 1, and a vacuum component for sucking the gas in the vacuum chamber 11. By adjusting the vacuum flow control component 22, the belt 3 can stably transmit electrode pieces of different sizes or different transmission speeds.

[0040] Please see the attached Figure 1 and Figure 2A vacuum chamber 11 for evacuating a vacuum to form a negative pressure environment is formed in the vacuum table 1. The vacuum table 1 includes a vacuum plate 12. Specifically, the vacuum plate 12 is a horizontally arranged long plate, and a vacuum hole 13 connected to the vacuum chamber 11 is opened through the vacuum plate 12.

[0041] Please see the attached Figure 3 The vacuum table 1 is provided with an air regulating pipe 2 in the vacuum chamber 11. The air regulating pipe 2 is installed on the side of the vacuum plate 12 close to the vacuum chamber 11. Specifically, the air regulating pipe 2 is vertically arranged so that the vacuum plate 12 is connected to the air regulating pipe 2 at the vacuum hole 13.

[0042] An air intake port 21 is provided at one end of the air regulating duct 2 away from the vacuum plate 12. Specifically, the air intake port 21 is a rectangular opening. When vacuuming, the gas flowing in the air regulating duct 2 is extracted at the air intake port 21, forming a negative pressure environment in the air regulating duct 2. It is understood that this is not a limitation on the specific shape of the air intake port 21, and those skilled in the art can replace it on this basis. For example, in other specific embodiments, the air intake port 21 is a circular opening. A vacuum flow control member 22 is provided at the air intake port 21 of the air regulating duct 2. The vacuum flow control member 22 adjusts the size of the air intake port 21 to control the gas flow at the air intake port 21.

[0043] Please see the attached Figure 1-3 The belt 3 is arranged around the outside of the vacuum table 1. The belt 3 is connected to a transmission drive 32. The transmission drive 32 drives the belt 3 to move to achieve the transmission of the electrode. The belt 3 is provided with suction holes 31. When the belt 3 moves to the vacuum plate 12, the suction holes 31 are arranged corresponding to the vacuum holes 13, so that the belt 3 can negatively adsorb the electrode at the suction holes 31. The transmission drive 32 is preferably, but not limited to, a DD motor drive. In some specific embodiments shown, a transmission roller is provided at the output end of the DD motor drive. The transmission roller is specifically arranged horizontally. The belt 3 passes around the transmission roller. When the transmission drive 32 drives the transmission roller to rotate, the transmission roller drives the belt 3 to move to transport the electrode. Furthermore, an auxiliary roller is provided on one side of the transmission roller. The auxiliary roller is arranged horizontally relative to the transmission roller. The belt 3 passes around the auxiliary roller and the transmission roller in sequence to form a wrap angle of the belt 3. The auxiliary roller adjusts its position in the vertical direction. The auxiliary roller and the transmission roller cooperate to adjust the wrap angle of the belt 3, thereby adjusting the tension of the belt 3, which can improve the transmission stability of the electrode. Furthermore, the transmission drive 32 is equipped with an intelligent control system that adjusts the conveying speed of the belt 3 as needed, and monitors its operating status in real time, improving operational convenience and adaptability. The manner in which the intelligent control system controls the transmission drive 32 is well known and practicable to those skilled in the art, and is not described in detail in this embodiment.

[0044] The vacuum table 1 has an exhaust port extending therethrough. A vacuum component is disposed on the vacuum table 1 and extracts gas from the vacuum chamber 11 at the exhaust port. The vacuum component is preferably, but not limited to, a vacuum pump. The vacuum component extracts gas from the vacuum chamber 11 and the air conditioning pipe 2 to create and maintain the desired vacuum environment.

[0045] During the vacuum adsorption and transmission process of the electrode, the vacuum component sucks the gas in the vacuum chamber 11, causing the adsorption holes 31 of the belt 3 to generate a pressure difference, and then the belt 3 can vacuum adsorb the electrode. When the transmission drive component 32 drives the belt 3 to move, the electrode adsorbed on the belt 3 moves with the movement of the belt 3, thereby realizing the transmission of the electrode. When the belt 3 transports electrode pieces of different sizes, the vacuum flow control component 22 adjusts the size of the air suction port 21 to adjust the gas flow of the air regulating pipe 2 at the air suction port 21. During the process of the vacuum component sucking the gas in the vacuum chamber 11 and the air regulating pipe 2, because the size of the air suction port 21 is adjusted and controlled by the vacuum flow control component 22, when the vacuum degree in the air regulating pipe 2 changes accordingly, the vacuum holes 13 and adsorption holes 31 of the belt 3 also change accordingly, thereby achieving different vacuum adsorption forces on the electrode.

[0046] The vacuum transmission mechanism controls and adjusts the vacuum flow in the air regulating pipe 2 according to the size of the electrode or the transmission speed, ensuring that electrodes of different sizes or different transmission speeds can be transmitted stably and efficiently, thereby improving the flexibility of use.

[0047] Example 2:

[0048] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the air regulating pipe 2 of the utility model. Figures 4-6 .

[0049] See Figure 4 and Figure 5 The vacuum flow control member 22 of this embodiment includes a flap 221. Specifically, the flap 221 is a rectangular long plate that matches the air inlet 21. By controlling the flipping of the flap 221 at the air inlet 21, the size of the opening of the air inlet 21 is adjusted, thereby adjusting the amount of air. That is, when the flap 221 rotates into the air regulating duct 2, the flap 221 gradually approaches the air inlet 21. As the flap 221 approaches the air inlet 21, the air intake of the air inlet 21 becomes smaller. When the flap 221 is completely in contact with the air inlet 21, The air intake 21 is in a closed state, with no air entering or exiting, and the air volume is zero; and when the flap 221 rotates toward the outside of the air regulating pipe 2, the flap 221 moves away from the air intake 21, and the air intake 21 is in an open state. As the flap 221 moves away from the air intake 21, the air intake volume increases, and when the air intake 21 is in a fully open state, the air intake volume reaches a maximum value; wherein, the flap 221 is rotatably connected to the air regulating pipe 2, and the rotation axis of the flap 221 is horizontally arranged and the axial direction is perpendicular to the transmission direction of the belt 3.

[0050] The vacuum table 1 is provided with a valve 222, which is connected to a flap 221. Rotating the valve 222 causes the flap 221 to flip, thereby adjusting the opening size of the air inlet 21. The valve 222 is mounted on the vacuum table 1. Specifically, the valves 222 are located on both sides of the vacuum table 1 along the conveying direction, allowing the operator to adjust the vacuum flow rate within the air regulating duct 2. In some specific embodiments shown, a scale is provided on one side of the valve 222. The scale can be used to control the rotation angle of the flap 221 to control the opening size of the air inlet 21, thereby regulating the air volume entering the air inlet 21, which is beneficial for improving the stability of the electrode conveying process.

[0051] In a preferred embodiment, a plurality of air regulating pipes 2 are provided, and the plurality of air regulating pipes 2 are distributed along the conveying direction of the belt 3. The provision of the plurality of air regulating pipes 2 is conducive to segmented adjustment of the vacuum degree of the vacuum plate 12 at the vacuum hole 13, so that the electrode can maintain the stability of transmission and improve the vacuum utilization rate in the vacuum chamber 11.

[0052] In a preferred embodiment, the air regulating pipe 2 is a funnel-shaped tube. Specifically, the wide end of the air regulating pipe 2 is connected to the corresponding side of the vacuum plate 12, so that the air regulating pipe 2 is connected to the vacuum hole 13 of the vacuum plate 12; the air suction port 21 is located at the narrow end of the air regulating pipe 2, and the gas in the air regulating pipe 2 is concentrated and flows through the air suction port 21, which is beneficial to improving the vacuum utilization rate and effectively avoiding the occurrence of vacuum leakage. In a preferred embodiment, the air regulating pipe 2 is tilted relative to the transmission direction of the belt 3. Specifically, the vacuum chamber 11 includes a symmetrically distributed left cavity and a right cavity. The air regulating pipe 2 in the left cavity can be tilted toward the right cavity, and the air regulating pipe 2 in the right cavity can be tilted toward the left cavity. This is beneficial to the rational use of the internal space of the vacuum table 1, and improves the vacuum utilization rate. It concentrates the control of the gas flow and can reduce the power of the vacuum parts when they are working.

[0053] See Figure 6In a preferred embodiment, a seal 4 is provided between the belt 3 and the vacuum plate 12. The seal 4 is located on the side of the vacuum plate 12 away from the vacuum chamber 11 and on one side of the vacuum hole 13. In some embodiments shown, multiple vacuum holes 13 are provided, arranged in multiple rows along the conveying direction of the belt 3. These vacuum holes 13 are specifically waist-shaped holes. Multiple adsorption holes 31 are also provided, so that the adsorption holes 31 are arranged corresponding to the vacuum holes 13. The seal 4 is located between two adjacent rows of vacuum holes 13. The seal 4 forms a sealed space between the belt 3 and the vacuum plate 12, reducing the impact of the external environment on the vacuum level at the vacuum holes 13 and within the vacuum chamber 11, allowing the belt 3 to stably adsorb the electrode. In some embodiments shown, the seal 4 is a sealing strip, preferably, but not limited to, a rubber sealing strip. The outer wall of the sealing strip is in contact with the corresponding side of the belt 3, enhancing the sealing performance of the vacuum plate 12 and thereby improving the stability of the vacuum environment.

[0054] See Figure 4 and Figure 5 When the vacuum flow control part 22 adjusts the vacuum degree, the vacuum flow valve is rotated, and the flap 221 is flipped to adjust the size of the air inlet 21. When the flap 221 is rotated to open the air inlet 21, the vacuum part evacuates the vacuum chamber 11, and the gas flow of the air regulating pipe 2 through the air inlet 21 is large. The belt 3 can form a large vacuum adsorption force at the adsorption hole 31, thereby adsorbing and fixing the electrode with a larger size or a faster transmission speed; and when the flap 221 is rotated to close the air inlet 21, the air regulating pipe 2 passes through the air inlet 2 1 The vacuum gas flow rate is small, and the vacuum adsorption force formed by the belt 3 at the adsorption hole 31 is small, thereby adsorbing and fixing the electrode with a small size or a slow transmission speed. The vacuum flow control part 22 adjusts the vacuum degree. Its operation is simple. Only by controlling the flap 221 to adjust the opening and closing state of the air suction port 21, the gas flow rate of the air regulating pipe 2 through the air suction port 21 can be adjusted to achieve control of the vacuum adsorption strength, which is beneficial to improving the stability and efficiency of the electrode transmission, thereby improving the overall production efficiency.

[0055] Example 3:

[0056] The difference between this embodiment and embodiment 1 is that this embodiment further includes a dust removal component 5, which is arranged on one side of the vacuum table 1. In some specific embodiments shown, the dust removal component 5 is located at the bottom of the vacuum table 1 to reduce the impact of dust falling. Figure 7 and Figure 8 .

[0057] The dust removal component 5 includes a brush roller 51 for cleaning the belt 3. Specifically, the brush roller 51 is arranged horizontally. During the process of the belt 3 conveying the pole piece, the material dust falling from the pole piece is easy to adhere to the surface of the belt 3. When the transmission drive member 32 drives the belt 3 to move, the belt 3 moves relative to the brush roller 51. The bristles of the brush roller 51 contact the surface of the belt 3 to clean the dust adhering to the belt 3, thereby improving the safety of the pole piece conveying process.

[0058] In a preferred embodiment, the dust removal assembly 5 also includes a mounting base 52, on which the brush roller 51 is mounted and detachably connected. Dust shields 53 are provided at both ends of the mounting base 52 in the conveying direction of the belt 3. The dust shields 53 are specifically vertically arranged long plates. The dust shields 53 can block dust shaken off by the brush roller 51 during the cleaning process, thereby further reducing the spread of dust and meeting the requirements of dust-free operation. In some specific embodiments shown, the dust shields 53 are rotatably connected to the mounting base 52. Specifically, the dust shields 53 and the mounting base 52 are hinged. When the dust shields 53 are opened, it is convenient for the operator to clean the brush roller 51, improving the convenience of operation.

[0059] A threaded handle 54 for locking the dust shield 53 is provided between the dust shield 53 and the mounting seat 52 . The threaded handle 54 passes through the dust shield 53 and is threadedly connected to the mounting seat 52 . At this time, the dust shield 53 covers the mounting seat 52 .

[0060] In a preferred embodiment, a roller 6 is provided on one side of the dust removal component 5, and the belt 3 moves around the roller 6 to the dust removal component 5. In some specific embodiments as shown, two rollers 6 may be provided, and the belt 3 is transmitted around the two rollers 6 in turn, which is conducive to ensuring the stability of the belt 3 transmission.
