Description

Technical Field

[0001] The utility model relates to the field of batteries, and particularly to a pole piece conveying mechanism and a stacked battery cell production device. Background Art

[0002] During the production process of stacked battery cells, it is necessary to convey the cut single pole pieces to different stations for operations such as detection, waste kicking, and stacking. Usually, a conveying mechanism is used to convey the pole pieces to each station. In the prior art, a conveying belt is arranged on the transmission mechanism to convey the pole pieces. The transition rollers on both sides of the conveying belt are equipped with bearings on both sides and a solid shaft in the middle. Because the distance between the bearing seats on both sides is far, it is very difficult to ensure the concentricity of the bearings on both sides. During the high-speed movement of the conveying belt, the transition rollers and the bearings on both sides bear large forces. Coupled with the problem of non-concentricity of the bearings on both sides, the bearings are easily damaged. And after the flat belt runs for a long time, its circumference will become larger, resulting in the belt not being tightened. In the prior art, the transition roller shaft is often designed to be movable in a groove, and by adjusting the positions of both ends of the transition roller shaft in the groove, the tension of the transition roller on the belt is adjusted. This tensioning method is very difficult to maintain a constant tension of the belt after the belt is elongated due to long-term operation, resulting in problems such as belt deviation and unstable pole piece positions.

[0014] As a further improvement of the above technical solution, the deviation rectifying driving member includes a deviation rectifying cylinder, the cylinder body of the deviation rectifying cylinder is mounted on the second fixing plate, and the piston rod of the deviation rectifying cylinder is connected with one end of the friction roller close to the second fixing plate through a ball eye joint.

[0015] As a further improvement of the above technical solution, the deviation rectifying assembly further includes an electromagnetic valve, and the electromagnetic valve is arranged outside the first fixing plate.

Detailed implementation manners

[0032] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all belong to the scope protected by the present utility model. In addition, all the connection / linkage relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to the specific implementation situation. For example, fixed connection / fixed installation can be selected from screw connection, bolt connection, pin connection, key connection, bonding, mortise and tenon connection, welding, riveting and other methods as needed, and detachable connection can be selected from screw connection, bolt connection, threaded connection, snap connection, mortise and tenon connection, magic tape connection and other methods as needed. Each technical feature in the creation of the present utility model can be interactively combined on the premise of not conflicting with each other.

[0033] Please refer to Figure 1, the present utility model provides a pole piece conveying mechanism, including a transmission belt 1, a driving assembly 2, a transition roller 3, and a pressing assembly 4. The transmission belt 1 is used for conveying pole pieces; the driving assembly 2 includes a belt driving member 21 and a driving roller 22. The belt driving member 21 is used for driving the driving roller 22 to rotate, and the driving roller 22 is used for driving the transmission belt 1 to move; the transition roller 3 includes a fixed roller 31, a plurality of limiting members 32, and a plurality of dividing rollers 33. Each dividing roller 33 is sleeved on the outer wall of the fixed roller 31, and each dividing roller 33 is arranged along the axial direction of the fixed roller 31. Each limiting member 32 is respectively arranged between two adjacent dividing rollers 33. The fixed roller 31 is in transmission connection with the driving roller 22 through a transmission member 311; the pressing assembly 4 includes a pressing driving member 41 and a pressing roller 42. The axial direction of the pressing roller 42 is perpendicular to the transmission direction of the transmission belt 1. The pressing driving member 41 is used for driving the pressing roller 42 to move towards or away from the transmission belt 1. Since the transition roller 3 includes a fixed roller 31, a plurality of limiting members 32, and a plurality of dividing rollers 33, each dividing roller 33 is sleeved on the outer wall of the fixed roller 31, and the dividing rollers 33 are arranged along the axial direction of the fixed roller 31. Each limiting member 32 is respectively arranged between two adjacent dividing rollers 33. The fixed roller 31 is in transmission connection with the driving roller 22 through a transmission member 311; when the belt driving member 21 is started, the driving roller 22 drives the transition roller 3 to rotate through the transmission member 311, and the transmission belt 1 moves under the drive of the two rollers. The arrangement of the plurality of limiting members 32 enables the fixed roller 31 to have multiple supports within a short distance, which can reduce the deformation degree of the fixed roller 31, thereby ensuring that the bearings at both ends of the dividing roller 33 do not generate excessive stress due to shaft deformation, optimizing the force-bearing situation of the traditional structure roller and bearing, reducing the belt tension force received by a single dividing roller 33, avoiding the force-bearing only through the bearings at both ends with a long span, and avoiding the problem of poor concentricity of the bearing seats at both ends caused by processing and assembly, improving the bearing load-bearing capacity and service life of the dividing roller, and being beneficial to improving the problem that the bearings and rollers are easily damaged. Since the pressing driving member 41 can drive the pressing roller 42 to move towards or away from the transmission belt 1, the pressing driving member 41 can apply a constant pressure to the transmission belt 1. Even if the transmission belt 1 is stretched during use, pressure can be applied to it to ensure that the tension force of the transmission belt 1 remains in a constant state, and it can prevent the situation that the transmission belt 1 cannot be tightened.

[0034] Please refer to Figure 2 and Figure 3, the pole piece conveying mechanism further includes a fixed support plate 5. There are two opposite mounting parts 51 arranged on the fixed support plate 5. Both ends of the fixed roller 31 are respectively mounted on the two mounting parts 51. Each limiting member 32 is arranged on the fixed support plate 5, and each limiting member 32 is provided with a notch 321. The notches 321 are coaxially arranged, and the fixed roller 31 is located within each notch 321. Both ends of each sub-roller 33 are connected with a bearing 331, and the fixed roller 31 passes through each bearing 331. The notch 321 can limit the fixed roller 31, prevent the transmission belt 1 from running off and causing the fixed roller 31 to deform, thereby preventing the bearing 331 from deforming.

[0035] Please refer to Figure 4 , the pressing assembly 4 further includes a mounting plate 43. A slide rail 431 is arranged on the mounting plate 43. The pressing roller 42 is connected with a connecting plate 421. The connecting plate 421 is connected with a slider 422, and the slider 422 is slidably connected with the slide rail 431. The pressing driving member 41 includes a pressing air cylinder 411. The cylinder body of the pressing air cylinder 411 is mounted on the mounting plate 43, and the piston rod of the pressing air cylinder 411 is connected with the connecting plate 421. When the pressing air cylinder 411 is started, its piston rod expands and contracts, thereby driving the connecting plate 421 to move up and down along the slide rail 431 through the slider 422, so that the pressing roller 42 moves towards or away from the transmission belt 1, realizing the pressure control of the transmission belt 1. The cooperation setting of the slider 422 and the slide rail 431 plays a guiding role in the expansion and contraction of the piston rod of the pressing air cylinder 411, ensuring the stability during the lifting process.

[0036] In this embodiment, the pressing assembly 4 further includes a pressure regulating valve 44. The pressure regulating valve 44 is arranged on the mounting plate 43, and the pressure regulating valve 44 is used to automatically keep the pressure of the pressing roller 42 on the transmission belt 1 stable.

[0037] The pole piece conveying mechanism further includes a mounting bracket 6. The driving roller 22 is mounted on the mounting bracket 6. The belt driving member 21 includes a servo motor 211. The servo motor 211 is mounted on the mounting bracket 6. The servo motor 211 is used to drive the driving roller 22 to rotate, thereby driving the transmission belt 1 to move. The servo motor 211 has excellent acceleration performance and overload capacity, which can ensure that the transmission belt 1 continuously and evenly feeds the pole pieces.

[0038] Please refer to Figure 1 , the pole piece conveying mechanism further includes a vacuum chamber 7. The transmission belt 1 is provided with adsorption holes (not shown in the figure). The vacuum chamber 7 is used to be connected with a negative pressure source so that a negative pressure is formed in the adsorption holes. The adsorption holes can adsorb the pole pieces on the transmission belt 1, preventing the pole pieces from falling out during the conveying process.

[0039] Please refer to Figures 5 - 7, the pole piece conveying mechanism further includes a deviation rectifying assembly 8, a first fixing plate 81 and a second fixing plate 82. The deviation rectifying assembly 8 includes a friction roller 83 and a deviation rectifying driving member 84. One end of the friction roller 83 is hinged to the first fixing plate 81 through a hinge member 85. A sliding groove 821 is provided on the second fixing plate 82, and the other end of the friction roller 83 is in clearance fit with the sliding groove 821. The deviation rectifying driving member 84 is used to drive the friction roller 83 to swing with the hinge member 85 as a fulcrum. When the deviation rectifying driving member 84 is activated, it drives the friction roller 83 to rotate with the hinge member 85 as a fulcrum and move back and forth in the sliding groove 821, thereby driving one end of the friction roller 83 to advance and retreat along the movement direction of the transmission belt 1.

[0040] The deviation rectifying driving member 84 includes a deviation rectifying cylinder 841. The cylinder body of the deviation rectifying cylinder 841 is installed on the second fixing plate 82, and the piston rod of the deviation rectifying cylinder 841 is connected to one end of the friction roller 83 close to the second fixing plate 82 through a spherical eye joint 842. Please refer to Figure 8 , the transmission direction of the transmission belt 1 is X. When the deviation rectifying cylinder 841 extends, the included angle between the friction roller 83 and the transmission belt 1 is α. A part of the frictional force between the transmission belt 1 and the friction roller 83 has a component force towards the outside. The transmission belt 1 is subjected to an outward frictional force component, causing the transmission belt 1 to move outward; Please refer to Figure 9 , when the deviation rectifying cylinder 841 retracts, the included angle between the friction roller 83 and the belt is β. The transmission belt 1 is subjected to an inward frictional force component, causing the transmission belt 1 to move inward.

[0041] Please refer to Figure 6 , the deviation rectifying assembly 8 further includes a solenoid valve 86. The solenoid valve 86 is arranged outside the first fixing plate 81. The solenoid valve 86 controls the piston rod of the deviation rectifying cylinder 841 to extend or retract by adjusting the air inlet and outlet directions, so as to achieve the effect of rectifying the transmission belt 1.

[0042] In this embodiment, a magnetic switch (not shown in the figure) is provided on the cylinder body of the deviation rectifying cylinder 841. The magnetic switch detects whether the current piston rod has completed the extension or retraction action by sensing the magnetic substance on the piston rod of the deviation rectifying cylinder 841.

[0043] In this embodiment, the pole piece conveying mechanism further includes a PLC (not shown in the figure) and an analog proximity sensor (not shown in the figure). The position of the conveyor belt 1 is detected in real time by the analog proximity sensor. When it is detected that the conveyor belt 1 deviates from the correct position in different directions by a certain distance, the analog proximity sensor sends a signal to the PLC. According to the received signal, the PLC controls the corresponding extension or retraction of the deviation rectifying cylinder 841, so as to control the friction roller 83 to form different angles with the running direction of the conveyor belt 1, and apply friction component forces in different directions to the conveyor belt 1, driving the conveyor belt 1 to move in the opposite direction, thereby realizing the small-range back-and-forth deviation rectification of the conveyor belt 1, ensuring that the conveyor belt 1 does not run out of the set range, and avoiding damage to the conveyor belt 1 caused by interference with other parts. The PLC can statistically analyze the deviation frequency of the conveyor belt 1 per unit time in real time according to the data provided by the analog proximity sensor. When it is detected that the deviation or deviation rectification frequency per unit time is significantly increased, a warning can be given for the deviation rectification frequency, and the output pressure of the pressing cylinder 411 can be automatically controlled to increase the tension of the conveyor belt 1, preventing the deviation rectification effect from getting worse due to the reduction of the tension of the conveyor belt 1. In addition, the deviation rectification cylinder 841 can be controlled to cooperate with the friction roller 83 to control the conveyor belt 1 to deviate only to a safe position, realizing the stable deviation rectification ability of the entire mechanism.

[0044] The friction roller 83 includes a main shaft 831 and a rolling part 832. The rolling part 832 is sleeved on the main shaft 831. Both ends of the rolling part 832 are connected to the main shaft 831 through first roller bearings 833. One end of the main shaft 831 is hinged to the first fixing plate 81 through a hinge 85, and the other end is connected to a spherical eye joint 842. A second roller bearing 834 is connected to the main shaft 831 near the second fixing plate 82; first bearing fixing rings 835 are connected to both sides of the rolling part 832 of the main shaft 831, and the main shaft 831 is also connected to a second bearing fixing ring 836. The second bearing fixing ring 836 is located between the second roller bearing 834 and the spherical eye joint 842. The first bearing fixing ring 835 and the second bearing fixing ring 836 are respectively used to prevent the first roller bearing 833 and the second roller bearing 834 from sliding along the axial direction of the main shaft 831.
