Lead acid battery pole group conveyor belt

Abstract

This utility model discloses a lead-acid battery electrode group conveyor belt, relating to the technical field of lead-acid battery production equipment. It includes a chain conveyor belt and multiple temporary storage units arranged along the conveying direction. Each temporary storage unit has a mounting base, with a first clamping plate and a second clamping plate slidably mounted on both sides of the base. A first wedge and a second wedge are respectively located at the lower ends of the two clamping plates. A gravity plate is positioned between the two clamping plates, with a first inclined surface and a second inclined surface on both sides of its lower end, respectively abutting against the first and second wedges. When electrode groups are placed on the gravity plate, the gravity plate moves downwards under its own weight and the gravity of the electrode groups. The inclined surfaces and wedges work together to drive the first and second clamping plates closer together, achieving adaptive clamping of the electrode groups. This conveyor belt can automatically adjust the clamping force according to the thickness or mass of different electrode groups, avoiding excessive or insufficient clamping force, effectively preventing lateral displacement or electrode plate damage during electrode group conveying, and improving transport stability and reliability.

Description

Technical Field

[0001] This utility model relates to the technical field of lead-acid battery production equipment, and in particular to a lead-acid battery electrode group conveyor belt. Background Technology

[0002] In lead-acid battery production, the pre-sinking of electrode groups is a core process, where positive and negative plates are clamped together with AGM separators to form electrode groups. Electrode groups are typically formed by alternating stacking of positive and negative plates and AGM separators in a pre-lamination stacking machine, and then transported by conveyor belt to the electrode packing machine for the pre-sinking process. The efficiency and stability of the electrode group conveyor belt directly affect the production cycle of the entire production line. However, during the stacking process, the electrode group consists of multiple layers of plates and separators stacked alternately, with the relative positions maintained only by a slight initial clamping force, resulting in a relatively loose overall structure. Furthermore, the thickness and width dimensions of electrode groups vary between different batches or models.

[0003] In the process of transferring electrode groups, the existing electrode group conveyor belts, due to the different thicknesses between individual electrode groups, are prone to excessive or insufficient clamping force when using existing fixed spacing and fixed clamping force. If the clamping force is too small, it is easy to cause lateral displacement of the electrode group during the transportation process, resulting in relative misalignment between the electrode plate and the AGM partition. If the clamping force is too large, it is easy to cause quality problems on the surface of the electrode plate. Utility Model Content

A first inclined surface and a second inclined surface are respectively disposed on both sides of the lower end of the gravity pressure plate, with the first inclined surface abutting against the first wedge and the second inclined surface abutting against the second wedge. When a pole group is placed on the gravity pressure plate, the gravity pressure plate can move vertically, causing the first clamping plate and the second clamping plate to move closer together.

[0011] According to some embodiments of the present invention, the chain conveyor belt includes a frame, a drive shaft, a driven shaft, a drive mechanism, and an adjustment mechanism. The drive mechanism is connected to the frame, and the output end of the drive mechanism is drivenly connected to the drive shaft. The drive shaft is rotatably mounted on the frame, and a first sprocket is mounted on the drive shaft.

[0012] According to some embodiments of the present invention, the driving mechanism includes a drive motor, a reducer, and a coupling. The output end of the drive motor is connected to the input end of the reducer, and the output end of the reducer is connected to the drive shaft via the coupling.

[0015] A lead-acid battery electrode group conveyor belt according to an embodiment of the present utility model has at least the following beneficial effects: According to the present invention, the clamping force is adaptively adjusted by using the self-weight of the gravity pressure plate and the gravity of the electrode group to drive the clamping plate. Without external power or sensors, the distance and clamping force between the first and second clamping plates can be automatically changed according to the actual mass or thickness difference of each electrode group. Compared with existing conveyor belts that use fixed spacing and fixed clamping force, this design avoids the problem of excessive or insufficient clamping force caused by the different thicknesses of individual electrode groups. When the clamping force is too small, the electrode group is prone to lateral displacement during conveying, causing relative misalignment between the electrode plate and the AGM partition; when the clamping force is too large, it may cause surface quality problems of the electrode plate. In this design, the clamping force is matched with the gravity of the electrode group itself, effectively eliminating the above risks. Furthermore, multiple temporary storage units are independently arranged along the chain conveyor belt, and each temporary storage unit independently adjusts its clamping state according to the electrode group it carries, allowing simultaneous processing of electrode groups of different thicknesses or weights without mutual interference. The chain conveyor belt drives the stable movement of each temporary storage unit and the internal electrode group through the transmission chain, which improves the reliability of the electrode group transfer process and helps maintain the production cycle of the entire line.

[0022] Reference Figures 1 to 6 As shown, this utility model discloses a lead-acid battery electrode group conveyor belt, including a chain conveyor belt 100 and a temporary storage unit 200. The chain conveyor belt 100 is provided with at least one drive chain 110; multiple temporary storage units 200 are provided along the conveying direction of the chain conveyor belt 100; each temporary storage unit 200 is provided with a mounting base 210, and a first clamping plate 220 and a second clamping plate 230 are slidably provided on both sides of the mounting base 210 in the horizontal direction. A first wedge block 221 is provided at the lower end of the first clamping plate 220, and a second wedge block 221 is provided at the lower end of the second clamping plate 230. A wedge 231; a gravity plate 240 is provided between the first clamping plate 220 and the second clamping plate 230, and the gravity plate 240 is slidably mounted on the mounting base 210 in the vertical direction; a first inclined surface 241 and a second inclined surface 242 are respectively provided on both sides of the lower end of the gravity plate 240, the first inclined surface 241 abuts against the first wedge 221, and the second inclined surface 242 abuts against the second wedge 231; when a pole group is placed on the gravity plate 240, the gravity plate 240 can move in the vertical direction and drive the first clamping plate 220 and the second clamping plate 230 to move closer to each other.

[0023] Specifically, in this embodiment, the lead-acid battery electrode group conveyor belt includes a chain conveyor belt 100. The chain conveyor belt 100 is provided with at least two drive chains 110 for the overall conveying of the electrode group. Multiple temporary storage units 200 are arranged along the conveying direction of the chain conveyor belt 100. Each temporary storage unit 200 is used to carry and hold one electrode group. Each temporary storage unit 200 is provided with a mounting base 210. A first clamping plate 220 and a second clamping plate 230 are slidably arranged horizontally on both sides of the mounting base 210. A first wedge block 221 is provided at the lower end of the first clamping plate 220, and a second wedge block 231 is provided at the lower end of the second clamping plate 230. A gravity pressure plate 240 is arranged between the first clamping plate 220 and the second clamping plate 230. The gravity pressure plate 240 is slidably arranged vertically on the mounting base 210. A first inclined surface 241 and a second inclined surface 242 are respectively provided on both sides of the lower end of the gravity pressure plate 240. The first inclined surface 241 abuts against the first wedge 221, and the second inclined surface 242 abuts against the second wedge 231. When no pole group is placed on the gravity plate 240, the gravity plate 240 is in its initial high position, and the first clamping plate 220 and the second clamping plate 230 are in a state of being far apart from each other in the horizontal direction. When a pole group is placed on the gravity plate 240, the gravity of the pole group causes the gravity plate 240 to move downward in the vertical direction. During the downward movement of the gravity plate 240, the first inclined surface 241 at the lower end of the gravity plate 240 slides relative to the first wedge 221, and the first inclined surface 241 pushes the first wedge 221 to move in the horizontal direction, thereby causing the first clamping plate 220 to move horizontally towards the second clamping plate 230. Simultaneously, the second inclined surface 242 and the second wedge 231 slide relative to each other. The second inclined surface 242 pushes the second wedge 231 to move horizontally, thereby causing the second clamping plate 230 to move horizontally closer to the first clamping plate 220. Therefore, the first clamping plate 220 and the second clamping plate 230 move closer to each other, achieving clamping of the pole group placed on the gravity pressure plate 240. The greater the mass of the pole group, the greater the downward distance of the gravity pressure plate 240, the greater the stroke of the first inclined surface 241 and the second inclined surface 242 pushing the first wedge 221 and the second wedge 231, the smaller the horizontal distance between the first clamping plate 220 and the second clamping plate 230, and the greater the clamping force applied to the pole group. Conversely, the smaller the mass of the pole group, the smaller the clamping force. Through the design of this structure, the weight of the gravity pressure plate 240 and the gravity of the pole group drive the clamping plate to move, realizing adaptive adjustment of the clamping force. Without external power or sensors, the spacing and clamping force between the first clamping plate 220 and the second clamping plate 230 can be automatically adjusted according to the actual mass or thickness difference of each electrode group. Compared with existing conveyor belts that use fixed spacing and fixed clamping force, this design avoids the problem of excessive or insufficient clamping force caused by the different thicknesses of individual electrode groups. When the clamping force is too small, the electrode group is prone to lateral displacement during conveying, causing relative misalignment between the electrode plate and the AGM partition; when the clamping force is too large, it may cause surface quality problems of the electrode plate.In this design, the clamping force is matched to the weight of the electrode group itself, effectively eliminating the aforementioned risks. Furthermore, multiple temporary storage units 200 are independently arranged along the chain conveyor belt 100. Each temporary storage unit 200 adjusts its clamping state independently according to the electrode group it carries, allowing for the simultaneous handling of electrode groups of different thicknesses or weights without mutual interference. The chain conveyor belt 100 drives the stable movement of each temporary storage unit 200 and the internal electrode group via the drive chain 110, improving the reliability of the electrode group transfer process and helping to maintain the overall production cycle time.

[0024] In some embodiments of this utility model, at least one guide rod 211 is provided on the mounting base 210, and a guide hole 243 is provided on the gravity plate 240 corresponding to the guide rod 211. The guide rod 211 is slidably disposed in the guide hole 243, and a return spring 212 is sleeved on the guide rod 211. The upper end of the return spring 212 abuts against the gravity plate 240, and the lower end of the return spring 212 abuts against the mounting base 210. Specifically, in this embodiment, two guide rods 211 are provided on the mounting base 210, and a guide hole 243 is provided on the gravity plate 240 corresponding to the guide rod 211. The guide rod 211 is slidably disposed in the guide hole 243. The cooperation between the guide rod 211 and the guide hole 243 provides a guiding effect for the vertical sliding of the gravity plate 240, restricts the horizontal displacement of the gravity plate 240, and ensures that the gravity plate 240 moves smoothly downward under the action of the gravity plate. A return spring 212 is fitted onto the guide rod 211. The upper end of the return spring 212 abuts against the gravity plate 240, and the lower end abuts against the mounting base 210. When the electrode group is placed on the gravity plate 240, the gravity plate 240 moves downward against the elastic force of the return spring 212, causing the first clamping plate 220 and the second clamping plate 230 to move closer together and clamp. When the electrode group is removed from the gravity plate 240, the elastic force of the return spring 212 pushes the gravity plate 240 upward, causing the gravity plate 240 to automatically return to its initial high position. The structure of the return spring 212 realizes the automatic return function of the temporary storage unit 200 in the no-load state, without manual intervention, improving the continuity and automation of equipment operation. The combination of guide rod 211 and guide hole 243 ensures the centering of gravity pressure plate 240 in reciprocating motion, and avoids poor contact between first inclined surface 241 and first wedge 221 and second inclined surface 242 and second wedge 231 due to skewness, thereby maintaining the stability and reliability of clamping force adjustment.

[0025] In some embodiments of this utility model, a first guide slider 222 is provided on the first wedge 221, a second guide slider 232 is provided on the second wedge 231, a first groove 244 is provided on the first inclined surface 241, and a second groove 245 is provided on the second inclined surface 242; the first guide slider 222 and the first groove 244 are slidably connected, and the second guide slider 232 and the second groove 245 are slidably connected. Specifically, in this embodiment, through the design of this structure, when the gravity pressure plate 240 moves in the vertical direction, the relative sliding between the first inclined surface 241 and the first wedge 221 is guided and limited by the cooperation of the first guide slider 222 and the first groove 244, and the relative sliding between the second inclined surface 242 and the second wedge 231 is guided and limited by the cooperation of the second guide slider 232 and the second groove 245. Compared to the free sliding method relying solely on the contact of inclined surfaces, the combination of the guide slider and the groove constrains the relative movement between the first wedge 221 and the first inclined surface 241, and between the second wedge 231 and the second inclined surface 242, in the direction perpendicular to the sliding direction, preventing the first wedge 221 or the second wedge 231 from laterally disengaging or deflecting during sliding. This design ensures the linearity and synchronicity of the horizontal movement of the first clamping plate 220 and the second clamping plate 230, improving the repeatability and positioning accuracy of the clamping action. Simultaneously, since the sliding contact surfaces always remain in the designed mating position, it reduces local stress concentration and surface wear caused by tilting or misalignment, extending the service life of the first inclined surface 241, the second inclined surface 242, the first wedge 221, and the second wedge 231. This structure further enhances the stability and reliability of the temporary storage unit 200 during long-term reciprocating motion, ensuring that the adaptive adjustment of the clamping force remains accurate and effective during continuous conveying of electrode groups of different thicknesses.

[0026] In some embodiments of this utility model, the mounting base 210 is provided with a third sliding groove 213 and a fourth sliding groove 214, and the sides of the first clamping plate 220 and the second clamping plate 230 are respectively slidably disposed in the third sliding groove 213 and the fourth sliding groove 214. Specifically, in this embodiment, the design of the third sliding groove 213 and the fourth sliding groove 214 ensures that the first clamping plate 220 and the second clamping plate 230 can stably move closer or further apart in the horizontal direction.

[0027] In some embodiments of this utility model, the first clamping plate 220 and the second clamping plate 230 are respectively provided with clearance holes 223. Specifically, in this embodiment, the clearance holes 223 facilitate the removal of the pole group located between the first clamping plate 220 and the second clamping plate 230 by other clamping mechanisms.

[0028] In some embodiments of this invention, an elastic layer is provided on the side of the first clamping plate 220 and the second clamping plate 230 that are close to each other. Specifically, in this embodiment, the elastic layer is made of synthetic rubber or silicone. When the gravity pressure plate 240 moves the first clamping plate 220 and the second clamping plate 230 close to each other and applies a clamping force to the electrode group, the elastic layer directly contacts the outer side of the electrode group. The elastic layer undergoes elastic deformation during the clamping process, making the clamping force of the first clamping plate 220 and the second clamping plate 230 on the electrode group more uniformly distributed, avoiding indentations or damage to the electrode surface caused by direct rigid contact between the hard material on the surface of the clamping plate and local protrusions or uneven thickness of the electrode group.

[0029] In some embodiments of this utility model, the chain conveyor belt 100 includes a frame 101, a drive shaft 120, a driven shaft 130, a drive mechanism 140, and an adjusting mechanism 150. The drive mechanism 140 is connected to the frame 101, and its output end is drively connected to the drive shaft 120. The drive shaft 120 is rotatably mounted on the frame 101, and a first sprocket 121 is mounted on the drive shaft 120. The adjusting mechanism 150 is connected to the frame 101, and its output end is drively connected to the driven shaft 130. The driven shaft is slidably mounted on the frame 101 in a horizontal direction, and a second sprocket 131 is mounted on the driven shaft 130. Specifically, in this embodiment, the drive mechanism 140 outputs power to the drive shaft 120, which drives the first sprocket 121 to rotate. The first sprocket 121 drives the transmission chain 110 to move, and the transmission chain 110 further drives the second sprocket 131 and the driven shaft 130 to rotate. The adjusting mechanism 150 applies a horizontal pushing or pulling force to the driven shaft 130 through its output end, causing the driven shaft 130 to slide horizontally relative to the frame 101, thereby changing the center distance between the first sprocket 121 and the second sprocket 131 and adjusting the tension of the transmission chain 110. This adjusting mechanism 150 can compensate for the slack in the transmission chain 110 caused by wear or plastic elongation during use, maintaining the correct meshing state between the chain and the first sprocket 121 and the second sprocket 131, preventing tooth skipping or chain derailment. Simultaneously, when the temporary storage unit 200 carries pole groups of different thicknesses, causing overall load changes, stable chain tension ensures the conveyor belt's conveying accuracy and operational stability, preventing lateral displacement or relative misalignment of the pole groups due to chain vibration or slippage. This structure separates the driving and tensioning functions. The drive shaft 120 is fixed to the frame 101 to ensure the coaxiality of the power input, while the driven shaft 130 can slide to achieve independent tension adjustment, which improves the reliability and maintenance convenience of the chain conveyor belt 100.

[0030] In some embodiments of this utility model, the drive mechanism 140 includes a drive motor 141, a reducer 142, and a coupling 143. The output end of the drive motor 141 is connected to the input end of the reducer 142, and the output end of the reducer 142 is connected to the drive shaft 120 via the coupling 143. Specifically, in this embodiment, the drive motor 141 outputs rotational power, which is reduced in speed and increased in output torque by the reducer 142, and then transmitted to the drive shaft 120 via the coupling 143. The drive shaft 120 drives the first sprocket 121 to rotate. The configuration of this drive mechanism 140 allows the chain conveyor belt 100 to select a suitable drive motor 141 and reducer 142 to match according to the linear speed and load torque required for the conveying of the chain. The reducer 142 provides a stable speed output and avoids speed fluctuations or overloads caused by direct motor drive. The coupling 143 serves as a connection and compensation between the output end of the reducer 142 and the drive shaft 120. It absorbs coaxiality errors generated during installation and buffers impact loads during starting and braking, protecting the drive shaft 120 and reducer 142 from additional bending moments or impact damage. This structure improves the assembly convenience and operational reliability of the drive system, and helps maintain the smooth operation of the chain conveyor belt 100 under conditions where multiple temporary storage units 200 continuously carry pole groups of different thicknesses, thereby ensuring the cycle stability and positional accuracy of the pole group transfer process.

[0031] In some embodiments of this utility model, the adjusting mechanism 150 includes a mounting plate 151, an adjusting block 152, and an adjusting screw 153. The mounting plate 151 is slidably connected to the frame 101 in the horizontal direction, the adjusting block 152 is fixedly connected to the frame 101, the adjusting screw 153 is threadedly connected to the adjusting block 152, and one end of the adjusting screw 153 passes through the adjusting block 152 and is rotatably connected to the mounting plate 151. The driven shaft 130 is rotatably connected to the mounting plate 151. Specifically, in this embodiment, when the operator rotates the adjusting screw 153, since the adjusting screw 153 and the adjusting block 152 fixed to the frame 101 are threadedly engaged, the adjusting screw 153 moves axially relative to the adjusting block 152 during rotation. Since one end of the adjusting screw 153 is rotatably connected to the mounting plate 151, the axial movement of the adjusting screw 153 will push or pull the mounting plate 151 to slide horizontally relative to the frame 101. Mounting plate 151 drives driven shaft 130 and second sprocket 131 to move horizontally synchronously, thereby changing the center distance between first sprocket 121 and second sprocket 131, achieving precise adjustment of the tension of transmission chain 110. This adjustment mechanism 150 uses a threaded drive and has a self-locking characteristic; once adjusted, the adjusting screw 153 will not loosen due to chain tension or vibration, maintaining the set tension for a long time. The horizontal sliding connection between mounting plate 151 and frame 101 ensures that the movement direction of driven shaft 130 is consistent with the chain tension direction, avoiding sprocket wear or chain misalignment caused by skew. This structure is simple and reliable, facilitating periodic adjustments by hand or tools, adapting to the elongation changes of transmission chain 110 throughout its service life, and maintaining the operational stability and positional accuracy of the chain conveyor belt 100 during the conveying of belts of different thicknesses.

[0032] In some embodiments of this utility model, the chain conveyor belt 100 further includes a tension sprocket 160. Specifically, in this embodiment, the tension sprocket 160 is disposed on the slack side of the drive chain 110 and is rotatably mounted on the frame 101 around its own axis, meshing or abutting with the outer or inner side of the drive chain 110. During the operation of the drive chain 110, the tension sprocket 160 applies a certain pressure or radial offset to the chain, further eliminating the slack of the chain and increasing the meshing wrap angle between the chain and the first sprocket 121 and the second sprocket 131. When the drive chain 110 elongates or wears due to long-term use, in addition to the adjustment mechanism 150 changing the center distance by moving the driven shaft 130, the tension sprocket 160 can locally supplement the tension of the chain.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
