[0002] In the lithium battery manufacturing process, especially after the slitting machine slits the batteries, a lot of electrode scraps are generated. These scraps need to be bagged and recycled. The current method is to bag them manually. However, manual bagging is not convenient for compression, and the material is very loose, resulting in a very light weight in each bag and low efficiency.

[0003] In addition, the electrode scraps have a coating on the electrode surface, which has great recycling value. However, the coating on these electrode scraps that were previously packed in bags could not be recycled, resulting in waste. Summary of the Invention:

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide an electrode compression and shaping device, which effectively solves the problem of low efficiency in manual bagging operations.

[0015] Working principle of the electrode compression and shaping device of this utility model:

[0016] Place the empty material frame onto the slide table. After loading the material frame, press the start button. The slide table, pushed by the slide table cylinder, slides down to directly below the transfer bucket at the second station. The transfer bucket, lifted by the transfer bucket lifting mechanism, is placed on top of the material frame. Then, the material frame and transfer bucket together slide down to the first station below the hopper under the action of the slide table cylinder. Manually remove the hopper cover and gradually feed in the electrode scraps. Then close the hopper cover, press the work button, and the material frame, transfer bucket, and electrode scraps together slide down to below the compression plate (the second station) under the action of the slide table cylinder. The compression plate moves downward under the action of the compression cylinder and guide rod to compress the material in the transfer bucket and material frame. Then the compression plate returns and descends again to compress the material in the transfer bucket and material frame. Then it returns to its original position. Next, the transfer bucket lifting mechanism holds the transfer bucket and rises to detach from the material frame. The slide table carries the material frame and slides down to the bottom of the hopper under the push of the slide table cylinder. The manual removal of the material frame full of electrode scraps completes the entire process of compression and shaping of electrode scraps. The removed material frame can be placed in a water soaking tank to remove the coating on the electrode scraps for recycling.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is exemplary and intended to provide further explanation of the present application; unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] The electrode compression and shaping device of this utility model includes a machine frame 1 and a slide table 9 mounted on the machine frame 1. The slide table 9 can be driven to slide by a slide table cylinder 10 or an electric push cylinder, etc.

[0028] A material frame 8 is placed on the slide table 9. The shape of the material frame 8 can be a cylinder or a square tube. The wall of the material frame 8 has water passage holes to facilitate subsequent immersion (or rinsing) to peel off the coating. The transfer bucket 12 is in the shape of a cylindrical tube (such as a round tube or a square tube). The cross-sectional shape of the transfer bucket 12 is the same as that of the material frame 8.

[0029] The lower port of the adapter bucket 12 is inserted and connected to the upper port of the material frame 8, and the upper port of the adapter bucket 12 is directly opposite to and close to the lower port of the hopper 11.

[0030] The material frame 8 has a first station and a second station on the slide table 9. Under the drive of the slide table cylinder 10, the material frame 8 and the slide table 9 can move and change between the first station and the second station. When the material frame 8 is in the first station, a hopper 11 fixed on the equipment frame 1 is provided directly above it. The electrode scraps can fall into the material frame 8 through the hopper 11. When the material frame 8 is in the second station, a liftable compression plate 14 is provided directly above it. The compression plate 14 can be used to compress the electrode scraps in the hopper 11, so that the fluffy electrode scraps in the material frame 8 are compressed, so that the material frame 8 of the same volume can accommodate a larger weight of electrode scraps.

[0031] To prevent the electrode scraps dropped into the hopper 11 from not falling accurately into the material frame 8, when the material frame 8 is in the second working position, a transfer bucket lifting mechanism 13 is provided above it for clamping and lifting the transfer bucket 12. The transfer bucket lifting mechanism 13 includes a lifting cylinder 131 and a transverse cylinder 132 fixed on the extension end of the lifting cylinder. The extension end of the transverse cylinder is used to clamp the transfer bucket 12. The lifting cylinder has two sets symmetrically arranged on the two outer sides of the compression plate 14. The upper end of the transfer bucket 12 has an outer flange 121. The extension end of the transverse cylinder (a fork plate 133 can be set at the extension end of the transverse cylinder, and the front end of the fork plate is concave arc-shaped) is supported on the lower surface of the outer flange.

[0032] In the initial state, the telescopic ends of the two transverse cylinders 132 are relatively close to each other to support the lower surface of the outer flange. When the material frame 8 moves to the second working position, the lifting cylinder 131 descends, and the lower port of the transfer barrel 12 and the upper port of the material frame 8 are fitted together with a gap. After the fitting and connection, the telescopic ends of the two transverse cylinders 132 are relatively far apart, so that the telescopic ends of the transverse cylinders 132 are no longer supported on the lower surface of the outer flange.

[0033] A compression cylinder 15 is vertically mounted on the equipment frame 1. The lower end of the telescopic rod of the compression cylinder 15 is vertically and fixedly connected to the compression plate 14. Several guide rods 16 are vertically and fixedly connected to the compression plate 14. The guide rods 16 are arranged around the outer periphery of the compression cylinder 15. Specifically, the cylinder body of the compression cylinder 15 is fixed on the platform surface 101 of the equipment frame 1. The telescopic rod of the compression cylinder 15 passes through the platform surface of the equipment frame 1 and connects to the compression plate 14. A guide sleeve is provided on the platform surface of the equipment frame 1. The guide rods 16 pass through the guide sleeve and connect to the compression plate 14. An outer cover 102 is provided around the compression cylinder 15 and the guide rods 16.

[0034] The hopper 11 is installed on the platform surface 101 of the equipment frame 1. The equipment frame 1 has a hopper cover 5 that can be flipped on the upper port of the hopper 11. The hopper cover 5 is rectangular and one side is rotatably connected to the platform surface. The equipment frame 1 has safety light curtains 6 on both sides of the hopper cover 5. That is, there is a row of infrared sensors forming a safety light curtain 6 on both sides of the hopper cover 5. The safety light curtain 6 can be used to confirm whether the hopper cover 5 is closed, so as to avoid starting the operation when the hopper cover 5 is not closed (the working principle of the safety light curtain 6 is the existing conventional technology, which will not be described in detail here).

[0035] The working principle of this utility model electrode compression and shaping device

[0036] Place the empty material frame 8 onto the slide table 9. After loading the material frame 8, press the start button 7 (which controls the operation of the slide table cylinder 10 and the transfer bucket lifting mechanism 13). The slide table 9 slides down under the push of the slide table cylinder 10 to directly below the transfer bucket 12 at the second station. The transfer bucket 12 is then placed on the material frame 8 by the action of the transfer bucket lifting mechanism 13. Then, the material frame 8 and the transfer bucket 12 slide down together under the action of the slide table cylinder 10 to the first station below the hopper 11. At this time, the hopper cover plate 5 can be manually removed to gradually feed in the electrode scraps. The electrode scraps fill the material frame 8 and reach the top of the transfer bucket 12. Then, close the hopper cover plate 5 and press the work button (which controls the slide table cylinder 10 and the compression cylinder 15). Then, the material frame 8 and the transfer bucket 12... Together with the electrode scraps, the material slides down to the compression plate 14 (second station) under the action of the slide cylinder 10. The compression plate 14 moves downward under the action of the compression cylinder 15 and the guide rod 16 to compress the material in the transfer bucket 12 and the material frame 8. Then the compression plate 14 returns and descends again to compress the material in the transfer bucket 12 and the material frame 8. Then it returns to its original position. Then the transfer bucket lifting mechanism 13 holds the transfer bucket 12 and rises to separate it from the material frame 8. The slide 9 carries the material frame 8 and slides down to the hopper 11 under the push of the slide cylinder 10. The material frame 8 filled with electrode scraps is then manually removed. This completes the entire process of compressing and shaping the electrode scraps. The removed material frame 8 can be placed in a water soaking tank to remove the coating on the electrode scraps for recycling.

[0037] This utility model electrode compression and shaping device effectively solves the problem of low efficiency in manual bagging operations.

Various modifications and variations can be made to this utility model by those skilled in the art.
