Description
Technical Field
[0001] This utility model relates to the field of used battery recycling and processing technology, specifically to a lead-acid battery clamping device. Background Technology
[0002] Lead-acid batteries are widely used in automobiles, electric vehicles, and backup power supplies. As they reach the end of their lifespan, a large number of used lead-acid batteries are generated. These used batteries contain lead, sulfuric acid electrolyte, and other substances. Improper disposal not only wastes resources but also causes serious environmental pollution. Therefore, the standardized recycling and disposal of used lead-acid batteries is crucial.
[0003] Currently, in the cutting process of waste lead-acid batteries, it is necessary to clamp the batteries. The purpose is usually to prevent the batteries from shifting or jumping during processing, or to increase the friction between the workpiece and the conveyor belt to assist in driving. In the existing technology, there are two common clamping methods: one is fixed clamping, such as using a fixed pressure plate or pressure bar; the other is simple elastic clamping, such as using a spring or cylinder to provide pressure so that the pressure roller presses against the surface of the workpiece.
[0004] The existing clamping devices with the above-mentioned structural forms have the following problems: 1. Fixed and most flexible clamping mechanisms can only provide clamping force in the vertical direction and cannot provide driving force in the horizontal direction for the workpiece. When the workpiece needs to be accurately and stably conveyed forward under clamping conditions, it must rely entirely on the friction of the conveyor belt. For workpieces with smooth bottom surfaces or heavy weights, slippage is likely to occur, leading to inaccurate positioning.
[0005] 2. For workpieces with uneven surfaces or fluctuating heights, simple elastic clamping can provide some cushioning, but its clamping force will change significantly with the workpiece height. When the workpiece height decreases, the clamping force may be insufficient, leading to clamping failure; when the workpiece height increases, excessive pressure may be generated, hindering conveying or even damaging the workpiece surface.
[0006] Therefore, there is an urgent need for a clamping device that can adapt to changes in the height of the workpiece and maintain a relatively stable clamping force. Summary of the Invention
[0007] This invention addresses the problems of existing clamping devices failing to provide horizontal driving force and unstable clamping force to workpieces by providing a lead-acid battery clamping device that can adapt to changes in workpiece height, maintain relatively stable clamping force, and is compact and reliable.
[0008] To achieve the above objectives, the technical solution of this utility model is as follows: A lead-acid battery clamping device is used to clamp the battery during the cutting process, including a drive device, a drive shaft driven to rotate by the drive device, and a clamping unit. The clamping unit includes an arc-shaped track centered on the drive shaft, an arc-shaped slider slidably disposed within the arc-shaped track, a driven shaft rotatably disposed on the arc-shaped slider, and a clamping wheel fixedly disposed at one end of the driven shaft. The clamping wheel is disposed above the conveyor belt. A transmission mechanism connects the drive shaft and the driven shaft. The drive shaft drives the driven shaft and the pressure wheel to rotate through the transmission mechanism.
[0009] Furthermore, the clamping device includes at least a first set of clamping units and a second set of clamping units. The first set of clamping units is located upstream of the cutting mechanism, and the second set of clamping units is located downstream of the cutting mechanism. The first set of clamping units is used for pre-clamping and aligning the battery; the second set of clamping units is used to maintain the stability of the battery during and after the cutting process.
[0010] Furthermore, the clamping device includes multiple drive shafts and multiple clamping units arranged in a one-to-one correspondence; the multiple drive shafts are connected by transmission and synchronously driven by the same drive device. This achieves multi-station synchronous clamping, ensuring uniform pressure on the battery.
[0011] Furthermore, the rim of the clamping wheel is provided with rectangular teeth. The clamping wheel is pressed against the battery, and the rectangular teeth are used to increase the friction between the clamping wheel and the battery.
[0012] Furthermore, the clamping roller is composed of multiple independent rollers arranged parallel and coaxially on the same driven shaft. This ensures uniform distribution of clamping force and avoids pressure concentration caused by single-point hard contact.
[0013] Furthermore, the transmission mechanism is a chain drive mechanism, a gear drive mechanism, or a synchronous belt drive mechanism. The transmission mechanism is any one of a chain drive mechanism, a gear drive mechanism, or a synchronous belt drive mechanism.
[0014] Furthermore, the transmission mechanism is a chain drive, with the pressure wheel fixed at one end of the driven shaft and a driven sprocket fixed at the other end, while a drive sprocket is fixed on the drive shaft. This achieves reliable power transmission from the drive shaft to the driven shaft.
[0015] Furthermore, the central angle of the arc-shaped track is between 30 and 90 degrees; in the initial state, the arc-shaped slider is located at the lowest end of the arc-shaped track near the conveyor belt under its own weight or the action of the elastic reset component; in the clamping state, the clamping wheel is lifted by the pushing action of the battery. The battery drives the arc-shaped slider to slide relative to the arc-shaped track.
[0016] Furthermore, the drive shaft is fixed to the frame via a bearing housing, and the driven shaft is connected to the drive shaft via a linkage mechanism, with both ends of the linkage mechanism forming revolute pairs with the drive shaft and the driven shaft, respectively. This linkage mechanism establishes a stable kinematic relationship between the driven shaft and the drive shaft, constraining the trajectory of the driven shaft's revolution around the drive shaft.
[0017] The beneficial effects of this utility model through the above technical solution are as follows: This invention features an arc-shaped track centered on a drive shaft, within which a driven shaft slides. One end of the driven shaft is fixed to a pressure wheel. The drive shaft transmits power to the driven shaft, causing the pressure wheel to rotate around its own axis, thus providing the driving function. Simultaneously, the driven wheel can revolve around the drive shaft's axis via an arc-shaped slider sliding along the arc-shaped track, adaptively pressing the battery. This mechanism integrates driving and adaptive pressing functions into a single, compact structure, achieving dynamic adaptive adjustment of the pressing force through mechanical means.

Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-2 As shown, this embodiment provides a lead-acid battery clamping device for clamping a battery 1 during a cutting process. It includes a drive device 58, a drive shaft 53 driven to rotate by the drive device 58, and a clamping unit. The clamping unit includes an arc-shaped track 50 centered on the drive shaft 53, an arc-shaped slider 54 slidably disposed within the arc-shaped track 50, a driven shaft 52 rotatably disposed on the arc-shaped slider 54, and a clamping wheel 51 fixedly disposed at one end of the driven shaft 52. A transmission mechanism connects the drive shaft 53 and the driven shaft 52, and the rotation of the drive shaft 53 drives the driven shaft 52 and the clamping wheel 51 to rotate around their own axis via the transmission mechanism.
[0020] The clamping wheel 51 is composed of multiple independent wheel bodies that are parallel and coaxially arranged on the same driven shaft 52.
[0021] The clamping device can be used in cutting devices, such as... Figure 2 As shown, taking the clamping device applied to a lead-acid battery cutting device as an example, the lead-acid battery cutting device includes a housing. A battery inlet and a battery outlet are respectively provided on both sides of the housing. A conveyor belt 3 passes between the inlet and outlet. A movable door is hinged to the front side of the housing. A clamping device and a cutting mechanism 2 are provided on the inner wall of the housing opposite to the movable door. The housing includes a front side and a rear side. The clamping wheel 51, the conveyor belt 3, and the cutting mechanism 2 are located on the front side of the housing. The drive shaft 53 and the drive device 58 are located on the rear side of the housing. The rear end of the driven shaft 52 extends from the front side of the housing to the rear side of the housing through the housing wall. The drive shaft 53 is rotatably located on the rear side of the housing.
[0022] Specifically, the clamping device clamps the battery 1 onto the conveyor belt 3, and the clamping wheel 51 is positioned above the conveyor belt 3; the arc-shaped track 50 is positioned on the inner wall of the front side of the housing, the arc-shaped slider 54 is slidably positioned within the arc-shaped track 50, the drive shaft 53 is rotatably positioned on the inner wall of the rear side of the housing via a bearing, and the drive device 58 is a motor, which drives the drive shaft 53 and drives the driven shaft 52 to rotate.
[0023] Preferably, the central angle of the arc track 50 is between 30 degrees and 90 degrees, and the two endpoints of the arc track 50 are located at the highest point and the lowest point, respectively. In the initial state, the arc slider 54 is located at the lowest end of the arc track 50 near the conveyor belt 3 under its own weight or the action of the elastic reset member. In the pressing state, the pressing wheel 51 is lifted by the pushing action of the battery 1.
[0024] When the battery 1 is conveyed to the clamping roller 51, the clamping roller 51 rotates around the axis of the driven shaft 52 under the drive of the motor. The lower edge of the clamping roller 51 presses against the upper surface of the battery 1. The rim of the clamping roller 51 is provided with rectangular teeth, which assists in conveying through friction. At the same time, the height change of the battery 1 is transmitted to the arc-shaped slider 54 through the clamping roller 51, forcing the arc-shaped slider 54 to slide along the arc-shaped track, thereby driving the entire driven shaft 52 and the clamping roller 51 to revolve around the center of the arc-shaped track 50, realizing the lifting and lowering of the clamping roller 51 to dynamically adapt to the shape of the battery 1 and maintain stable clamping.
[0025] The lower edge of the clamping roller 51 moves in the same direction as the conveying direction of the conveyor belt 3, and both operate at the same speed to achieve the effect of clamping and stabilizing the feeding. A groove is provided inside the arc-shaped track 50, and a protrusion matching the groove is provided outside the arc-shaped slider 54 to achieve sliding engagement between the arc-shaped slider 54 and the arc-shaped track 50, preventing the arc-shaped slider 54 from slipping off.
[0026] To ensure effective clamping, the clamping device includes at least a first set of clamping units and a second set of clamping units. The first set of clamping units is located upstream of the cutting mechanism 2, and the second set of clamping units is located downstream of the cutting mechanism 2, enabling the cutting mechanism 2 to achieve stable clamping during the cutting process. Figure 2 The diagram shows three sets of clamping rollers. In the case where the clamping device includes multiple drive shafts 53 and multiple clamping units arranged in a one-to-one correspondence, in one embodiment, the multiple drive shafts 53 are connected by chain drive and synchronously driven by the same drive device 58. This achieves multi-station synchronous clamping, ensuring uniform pressure on the battery 1. In this case, the drive shafts 53 and driven shafts 52 are arranged at intervals.
[0027] A transmission mechanism is connected between the drive shaft 53 and the driven shaft 52. The transmission mechanism is a chain drive, a gear drive, or a synchronous belt drive. In this embodiment, the transmission mechanism is a chain drive. One end of the driven shaft 52 is fixed to the pressure wheel 51, and the other end is fixed to the driven sprocket 55. The drive shaft 53 is fixed to the drive sprocket 56, and the drive sprocket 56 and the driven sprocket 55 are connected by a chain.
[0028] To ensure structural stability, the drive shaft 53 is fixed to the frame 4 via bearing seats. One end of the drive shaft is rotatably supported by a bearing on the side wall of the housing, and the other end is rotatably supported by a bearing on the upright plate of the frame 4, forming a double-support structure to ensure the rigidity and stability of the drive shaft 53 during rotation. The driven shaft 52 is connected to the drive shaft 53 via a linkage mechanism 57, and the two ends of the linkage mechanism 57 form a rotating pair with the drive shaft 53 and the driven shaft 52, respectively. This ensures that the driven shaft 52 maintains a stable relative position during its revolution around the drive shaft 53. Both the drive shaft 53 and the driven shaft 52 are equipped with limit structures to prevent axial movement. Through the above-mentioned multi-point synergistic constraints, the drive shaft 53 and the driven shaft 52 have high motion stiffness and positioning accuracy during rotation and oscillation, effectively suppressing vibration and sway, and ensuring the smooth operation of the pressure roller 51.
[0029] In use, the battery 1 is conveyed to the pressing device by the conveyor belt 3. Its top contacts the pressing wheel 51 and applies a pushing force, which pushes the pressing wheel 51 and the driven shaft 52 to revolve around the axis of the drive shaft 53. This drives the arc-shaped slider 54 to slide along the arc-shaped track 50 away from the conveyor belt 3, so that the pressing wheel 51 presses the surface of the battery 1 with a set pressure under its own weight and the pushing force of the battery 1. At the same time, the drive device 58 drives the driven shaft 52 and the pressing wheel 51 to rotate around its own axis through the chain drive mechanism via the drive shaft 53. The friction between the rectangular teeth of the pressing wheel 51 and the surface of the battery 1 is used to assist the conveyor belt 3 in pushing the battery 1 smoothly through the cutting station.
