Description

Technical Field

[0001] This utility model relates to the field of battery electrode technology, and in particular to an electrode stacking mechanism. Background Technology

[0002] The plates are the core components of a battery, consisting of positive and negative plates, which are composed of active materials and current collectors, respectively. Their function is to store and release electrical energy through electrochemical reactions. The quality of the plates directly affects the battery's capacity, energy density, and lifespan.

[0003] In the battery manufacturing process, the electrode plates, as core components, need to go through multiple processes such as coating, slitting, drying, and stacking. The conveying speed of individual equipment in each stage (such as coating machine, rolling mill, die-cutting machine, etc.) varies significantly. If single electrode plates are directly conveyed, the speed mismatch will lead to electrode plate accumulation, displacement, or even collision damage.

[0004] Therefore, battery manufacturers coordinate the rhythm between processes by designing stacking on the conveyor belt, so that the plates are placed in a stacked form before entering the single machine. The existing design uses suction cups to adsorb the plates, thereby achieving the stacking of multiple plates. However, the suction cups need to frequently perform adsorption-release actions, which limits the efficiency of the suction cups in adsorbing and placing the plates. Consequently, the conveyor belt's conveying efficiency cannot be maximized, resulting in poor plate stacking efficiency. Utility Model Content

[0005] The main purpose of this utility model is to provide a plate stacking mechanism. The conveying height of the first tracked conveyor is higher than that of the second tracked conveyor. Therefore, when the plate moves onto the second tracked conveyor, it will drop significantly. The positioning device can limit the position of the plate on the second tracked conveyor, thereby realizing the plate stacking operation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A plate stacking mechanism includes a first tracked conveyor and a second tracked conveyor. The height of the first tracked conveyor is higher than that of the second tracked conveyor. Plates are provided on both sides of the junction of the first tracked conveyor and the second tracked conveyor. Limiting components are provided on the two plates. Positioning devices are also provided on the two plates. The positioning device includes a linear drive device fixed on the plate. A baffle is fixed to the top drive end of the linear drive device.

[0008] Furthermore, the positioning device includes a connecting rod threaded to the plate body, and a limit rod is fixed at one end of the connecting rod.

[0009] Furthermore, a roller is rotatably connected between the two plates, and a motor is installed on one of the plates. The power output shaft of the motor is fixedly connected to the roller. A gap is left between the roller and the first tracked conveyor, and the roller is located above the conveying end of the first tracked conveyor.

[0010] Furthermore, a counting device is provided on one of the plates.

[0011] Furthermore, the counting device includes a counter and a mounting plate connected to the plate body. A swing arm is rotatably connected to the mounting plate via a shaft, and the detection head of the counter is fixed to the mounting plate.

[0012] Furthermore, the linear drive device is a cylinder.

[0013] Furthermore, the counter is a photoelectric induction counter.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The conveying height of the first tracked conveyor of this utility model is higher than that of the second tracked conveyor. Therefore, when the electrode plate moves onto the second tracked conveyor, it will drop significantly. The positioning device can limit the position of the electrode plate on the second tracked conveyor, thereby realizing the stacking operation of the electrode plate.

[0016] The distance between the two limiting rods of this utility model is slightly larger than the width of the electrode plate (including the frame). When the electrode plate moves onto the second track conveyor, the side of the frame of the electrode plate will contact the limiting rod. Therefore, the two limiting rods can make the electrode plate fall accurately onto the second track conveyor, avoiding large left and right deviations when the electrode plates are stacked.

[0017] The motor of this invention drives the roller to rotate. When the electrode plate passes through the gap between the roller and the first tracked conveyor, it will come into contact with the roller, thereby causing the rotating roller to apply force to the electrode plate. As a result, the electrode plate can obtain sufficient kinetic energy under the action of the first tracked conveyor and the roller, and fall onto the second tracked conveyor at a relatively horizontal angle.

[0018] In this invention, the moving electrode plate will collide with the swing arm, causing the swing arm to swing once. At this time, the detection head can detect the swing of the swing arm and count the number of stacked electrode plates by the swing of the swing arm. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-3 As shown, an electrode plate stacking mechanism includes a first tracked conveyor 1 and a second tracked conveyor 2. The height of the first tracked conveyor 1 is higher than that of the second tracked conveyor 2. Plates 3 are provided on both sides of the junction of the first tracked conveyor 1 and the second tracked conveyor 2. Limiting components 8 are provided on the two plates 3. Positioning devices 7 are also provided on the two plates 3. The positioning device 7 includes a linear drive device 701 fixed on the plate 3. A baffle 702 is fixed to the top drive end of the linear drive device 701. The linear drive device 701 is a cylinder. The width of the second tracked conveyor 2 is smaller than that of the first tracked conveyor 1. When the electrode plate is conveyed on the second tracked conveyor 2, the edge of the electrode plate will be located outside the second tracked conveyor 2.

[0025] In this embodiment, such as Figure 1 As shown, the electrode plates are first conveyed on the first tracked conveyor 1, and then conveyed to the second tracked conveyor 2 via the first tracked conveyor 1. During this process, since the conveying height of the first tracked conveyor 1 is higher than that of the second tracked conveyor 2, the electrode plates will have a significant drop when they move to the second tracked conveyor 2. Thus, the stacking operation of the electrode plates is achieved through the height difference between the first tracked conveyor 1 and the second tracked conveyor 2.

[0026] During the stacking operation, the second tracked conveyor 2 stops conveying, and the linear drive device 701 drives the baffle 702 to rise, so that when the electrode plate moves onto the second tracked conveyor 2, the edge of its frame will contact the baffle 702. This causes the baffle 702 to limit the position of the electrode plate falling onto the second tracked conveyor 22, so that multiple electrode plates are stacked neatly. When the number of electrode plates stacked reaches a preset number, the second tracked conveyor 2 starts to work and conveys the stacked electrode plates.

[0027] Among them, such as Figure 1 and Figure 2 As shown, the positioning device 7 includes a connecting rod 801 threadedly connected to the plate 3. One end of the connecting rod 801 is fixed with a limiting rod 802. The distance between the two limiting rods 802 is slightly greater than the width of the electrode plate (including the frame). When the electrode plate moves onto the second track conveyor 2, the side of the frame of the electrode plate will contact the limiting rod 802. Therefore, the two limiting rods 802 can make the electrode plate fall accurately onto the second track conveyor 22, avoiding large left and right deviations when the electrode plates are stacked.

[0028] Among them, such as Figure 1 and Figure 2 As shown, a roller 4 is rotatably connected between two plates 3. A motor 5 is installed on one of the plates 3. The power output shaft of the motor 5 is fixedly connected to the roller 4. The motor 5 drives the roller 4 to rotate. There is a gap between the roller 4 and the first tracked conveyor 1, and the roller 4 is located above the conveying end of the first tracked conveyor 1. When the electrode plate passes through the gap between the roller 4 and the first tracked conveyor 1, it will contact the roller 4, so that the roller 4 applies force to the electrode plate. In turn, the electrode plate can obtain sufficient kinetic energy under the action of the first tracked conveyor 1 and the roller 4, and fall onto the second tracked conveyor 22 at a relatively horizontal angle.

[0029] Among them, such as Figure 1 and Figure 2 As shown, a counting device 6 is provided on one of the plates 3. The counting device 6 includes a counter 603 and a mounting plate 605 connected to the plate 3. A swing arm 601 is rotatably connected to the mounting plate 605 via a shaft 602. The detection head 604 of the counter 603 is fixed on the mounting plate 605. The counter 603 is a photoelectric induction counter.

[0030] During the process of the electrode plate moving from the first tracked conveyor 1 to the second tracked conveyor 2, the moving electrode plate will hit the swing arm 601, causing the swing arm 601 to swing once. At this time, the detection head 604 can detect the swing of the swing arm 601, and then count the number of electrode plates stacked by the swing of the swing arm 601. When the number of electrode plates stacked reaches the target, the second tracked conveyor 2 is controlled to work.

[0031] Working principle: The electrode plates are first conveyed by the first tracked conveyor 1. Since the conveying height of the first tracked conveyor 1 is higher than that of the second tracked conveyor 2, the electrode plates will experience a significant drop when they move onto the second tracked conveyor 2. This height difference between the first and second tracked conveyors 1 and 2 enables the electrode plates to be stacked. Simultaneously, the operator controls the motor 5, which drives the roller 4 to rotate. The electrode plates can contact the roller 4 as they pass through the gap between the roller 4 and the first tracked conveyor 1, causing the roller 4 to apply force to the electrode plates. This allows the electrode plates to gain sufficient kinetic energy under the action of the first tracked conveyor 1 and the roller 4, falling at a relatively horizontal angle onto the second tracked conveyor 22. During this process, the second tracked conveyor 2 stops conveying and resumes linear drive. The device 701 drives the baffle 702 to rise, so that when the electrode plate moves onto the second tracked conveyor 2, the edge of its frame will contact the baffle 702. This allows the baffle 702 to limit the front and rear positions of the electrode plate as it falls onto the second tracked conveyor 22. During this process, the side edge of the electrode plate will also contact the limiting rod 802 to prevent large lateral deviations when the electrode plates are stacked, ensuring that multiple electrode plates are stacked neatly. When the electrode plate falls onto the second tracked conveyor 22, it will hit the swing arm 601, causing the swing arm 601 to swing once. At this time, the detection head 604 can detect the swing of the swing arm 601 and count the number of stacked electrode plates by the swing of the swing arm 601. When the number of stacked electrode plates reaches the target, the operator controls the second tracked conveyor 2 to transport the stacked electrode plates.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
