Description

A feeding and storage device for electrode sheets before welding Technical Field

[0001] This utility model belongs to the field of battery processing technology and relates to a feeding and storage device for electrode sheets before welding. Background Technology

[0002] With the rapid development of the new energy industry, power batteries and energy storage batteries, as core components, have manufacturing processes that directly affect the performance and safety of end products. Among these processes, the electrode welding process is a crucial step in battery assembly. High-precision equipment is required to stably connect the positive and negative electrodes to components such as tabs and busbars to ensure the battery's conductivity, cycle life, and thermal stability. Electrode sheets are typically composed of a metal substrate (such as copper or aluminum foil) and an active material coating layer. They are thin, flexible, and fragile, requiring extremely high adaptability to tooling and process parameters during manufacturing.

[0003] In the pre-welding process of electrode sheets, the efficiency and stability of the feeding stage directly affect the automation level of the entire production line. Currently, electrode sheets are often temporarily stored in open bins or stacked containers before welding. However, the disorderly stacking without pre-sorting causes frequent misalignment, jamming, and even tearing of the feeding robot or conveyor belt during handling, severely restricting the feeding cycle time and yield. Especially in high-speed automated production lines, the static storage mode of traditional bins is difficult to match dynamic feeding requirements, and stress concentration generated during electrode sheet stacking can also cause micro-cracks, indirectly affecting the stability of subsequent processes. Furthermore, existing feeding devices mostly rely on manual pre-sorting or simple vibratory feeders for initial sorting, but their tolerance for differences in electrode sheet curvature, dimensional tolerances, and surface contamination is low, leading to increased equipment downtime. Summary of the Invention

[0004] The purpose of this invention is to provide an electrode sheet feeding and storage device before welding, which can store and feed electrode sheets in an orderly manner, thereby helping to improve the overall welding efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a feeding and storage device for electrode sheets before welding, including a support, a storage box with an open top connected movably inside the support, a drive motor for driving the storage box to move along its length direction mounted on the support, a strip-shaped discharge part arranged along its length direction at the bottom of one side of the storage box, the bottom of the storage box inclined downward toward the strip-shaped discharge part, and the bottom of the strip-shaped discharge part inclined downward along the inclined direction of the bottom of the storage box;

[0006] The storage box is divided into multiple storage areas by multiple vertical partitions that are perpendicular to the downward-sloping side of the storage box. Each storage area has a discharge storage trough that is movably installed at the strip-shaped discharge section. Each storage area also has multiple stepped storage troughs that are movably installed outside the strip-shaped discharge section and distributed along its length. The bottom of each discharge storage trough is inclined along the bottom of the strip-shaped discharge section, and the bottom of each stepped storage trough is inclined along the bottom of the storage box. Each discharge storage trough and each stepped storage trough has openings on both sides perpendicular to the vertical partitions. Each opening of each discharge storage trough and each stepped storage trough has a baffle that can be pulled upwards that can be detachably connected to both sides.

[0007] The strip-shaped discharge section has strip-shaped discharge holes and strip-shaped sliding holes on both sides of the bottom of each storage area, perpendicular to the vertical partition. Each strip-shaped discharge hole is located on the downward-sloping side of the storage box. The support is equipped with a telescopic motor below the storage box. The telescopic motor is inclined along the inclined direction of the bottom of the storage box. The power output shaft of the telescopic motor is connected to an inclined push bar that is slidably connected to the strip-shaped sliding hole.

[0008] By adopting the above technical solution, firstly, electrode plates are filled into the discharge storage tank and the stepped storage tank. Then, the discharge storage tank and the stepped storage tank containing the electrode plates are placed into the storage area. The baffles on both sides are pulled out upwards, so that the openings of the discharge storage tank and the stepped storage tank are connected. When feeding, the telescopic motor extends and retracts to push the inclined push bar through the strip-shaped sliding hole into the bottom of the discharge storage tank, pushing the electrode plate at the bottom of the discharge storage tank out of the strip-shaped discharge hole. After the telescopic motor drives the inclined push bar to reset, the discharge storage tank... The inner electrode plates are lowered to fill the gap under the action of gravity. At this time, there is a height difference between the electrode plates at the top of the discharge storage tank and the electrode plates at the top of the stepped storage tank. The electrode plate at the top of the stepped storage tank will slide to the top of the discharge storage tank under the action of gravity to fill the gap. The electrode plates at the top of the stepped storage tank will fill the gap in this way until the electrode plates inside are consumed. Then, the drive motor drives the storage box to move through the threaded drive shaft, so that the next storage area is aligned with the telescopic motor, and the electrode plates in this storage area are loaded.

[0009] The present invention is further configured such that a threaded sleeve is provided on the outer side of the storage box along its length direction, a threaded drive shaft is rotatably connected to the threaded sleeve inside the bracket, and the power output shaft of the drive motor is connected to one end of the threaded drive shaft.

[0010] The present invention is further configured such that a limiting shaft is connected inside the bracket and is arranged along the length direction of the threaded drive shaft, and a limiting sleeve is provided outside the storage box and is slidably connected to the limiting shaft.

[0011] The present invention is further configured such that the upper part of each discharge storage tank and each stepped storage tank extends out of the storage box, and each discharge storage tank and each stepped storage tank has a slide rail on both sides of the opening that is slidably connected to the corresponding baffle, and each slide rail is located above the storage box.

[0012] The present invention is further provided with a handle at the top of each discharge storage tank and each stepped storage tank.

[0013] The present invention is further provided that an elastic blocking strip is provided at each strip discharge hole on the downward inclined side of the strip discharge section.

[0014] The present invention is further configured such that the elastic blocking strip is made of silicone material.

[0015] The present invention is further configured such that a horizontal slide rail is provided at the strip sliding hole on the side of the strip discharge section away from the strip discharge hole, which is slidably connected to the inclined push bar.

[0016] The present invention is further configured such that the telescopic motor is a voice coil motor.

[0017] Compared with the prior art, this utility model adopts a partitioned stepped storage method, using discharge storage tanks and stepped storage tanks to store electrode sheets in an orderly manner. It has a large storage capacity. During loading, the bottom electrode sheets are pushed out by a telescopic motor driven by an inclined pusher. Since the electrode sheets are placed at an incline, they will automatically fill in the gaps under the action of gravity, allowing them to automatically fill in the discharge storage tanks. This eliminates the need for other transfer mechanisms to push out all the electrode sheets in a storage area one by one for orderly loading. It does not require a complex loading structure and can help improve the overall welding efficiency. Attached Figure Description

[0023] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the electrode sheet feeding and storage device proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, used only to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0024] Referring to Figures 1-4, an electrode sheet pre-welding material storage device includes a support 1. A storage box 2 with an open top is movably connected inside the support 1. A threaded sleeve 3 is provided on the outer side of the storage box 2 along its length. A threaded drive shaft 4, threadedly connected to the threaded sleeve 3, is rotatably connected inside the support 1. The length of the threaded drive shaft 4 is twice that of the storage box 2. A drive motor 5 is mounted on the outer side of the support 1. The power output shaft of the drive motor 5 is connected to one end of the threaded drive shaft 4, allowing the drive motor 5 to drive the storage box 2 to slide. A limiting shaft 6, extending along the length of the threaded drive shaft 4, is connected inside the support 1. A limiting sleeve 7, slidably connected to the limiting shaft 6, is provided outside the storage box 2. A strip-shaped discharge section 8, extending along its length, is provided downwards on one side of the bottom of the storage box 2. The bottom of the storage box 2 slopes downwards towards the strip-shaped discharge section 8, and the bottom of the strip-shaped discharge section 8 slopes downwards along the slope direction of the bottom of the storage box 2.

[0025] The storage box 2 is divided into eight storage areas 10 by seven vertical partitions 9 that are inclined downwards on one side of the vertical storage box 2. Each storage area 10 has a discharge storage trough 11 that is movably installed at the strip discharge section 8. Each storage area 10 also has two stepped storage troughs 12 that are movably installed outside the strip discharge section 8 and distributed along its length. The bottom of each discharge storage trough 11 is inclined along the bottom of the strip discharge section 8, and the bottom of each stepped storage trough 12 is inclined along the bottom of the storage box 2. Both sides of each discharge storage trough 11 and each stepped storage trough 12 are open, so that the electrode sheet can move between the discharge storage trough 11 and the stepped storage trough 12 with gravity. Each discharge storage tank 11 and each stepped storage tank 12 has a baffle 13 that can be pulled upwards detachably connected to both sides of its opening. The upper part of each discharge storage tank 11 and each stepped storage tank 12 extends out of the storage box 2. Each discharge storage tank 11 and each stepped storage tank 12 has a slide rail 14 that is slidably connected to the corresponding baffle 13 on both sides of its opening. Each slide rail 14 is located above the storage box 2 so as not to obstruct the sliding of the electrode sheet. Each discharge storage tank 11 and each stepped storage tank 12 has a handle 15 at its upper end.

[0026] The strip-shaped discharge section 8 has a strip-shaped discharge hole 16 and a strip-shaped sliding hole 17 on both sides of the vertical partition 9 at the bottom of each storage area 10. Each strip-shaped discharge hole 16 is located on the downward-sloping side of the storage box 2. On the downward-sloping side of the storage box 2, an elastic blocking strip 18 made of silicone material is provided at each strip-shaped discharge hole 16 to prevent the electrode sheet from sliding out of the strip-shaped discharge hole 16 under the action of gravity. A telescopic motor 19 is installed on the support 1 below the storage box 2. The telescopic motor 19 is a voice coil motor, which can perform telescopic extension and retraction at higher speeds. The telescopic motor 19 is inclined along the inclined direction of the bottom of the storage box 2. The power output shaft of the telescopic motor 19 is connected to an inclined pusher 20 that is slidably connected to the strip-shaped sliding hole 17. On the side of the strip-shaped discharge section 8 away from the strip-shaped discharge hole 16, a horizontal slide rail 21 is provided at the strip-shaped sliding hole 17 that is slidably connected to the inclined pusher 20.

[0027] Working principle: First, fill the discharge storage tank 11 and the stepped storage tank 12 with electrode plates. Then, place the discharge storage tank 11 and the stepped storage tank 12 with electrode plates into the storage area 10. Pull out the baffles 13 on both sides upwards to connect the openings of the discharge storage tank 11 and the stepped storage tank 12. When feeding, the telescopic motor 19 extends and pushes the inclined push bar 20 through the strip-shaped sliding hole 17 into the bottom of the discharge storage tank 11, pushing the electrode plate at the bottom of the discharge storage tank 11 away from the elastic blocking bar 18 and pushing it out of the strip-shaped discharge hole 16. The telescopic motor 19 drives the inclined push bar 20 to reset. Then, the electrode plates in the discharge storage tank 11 are moved downward under the action of gravity to fill the gap. At this time, there is a height difference between the electrode plates at the top of the discharge storage tank 11 and the electrode plates at the top of the stepped storage tank 12. The electrode plate at the top of the stepped storage tank 12 will slide to the top of the discharge storage tank 11 under the action of gravity to fill the gap. The electrode plates at the top of the stepped storage tank 12 will also fill the gap in this way until the electrode plates inside are consumed. Then, the drive motor 5 drives the storage box 2 to move through the threaded drive shaft 4, so that the next storage area 10 is aligned with the telescopic motor 19, and the electrode plates in this storage area 10 are loaded.

[0028] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.
