Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a manual-assisted stacking machine for experimental use. Background Technology

[0002] In battery research and development experiments, positive and negative electrode plates are often stacked alternately to prepare experimental battery cells. During this process, a separator is also needed between two adjacent positive and negative electrode plates to prevent the positive and negative electrode plates from coming into direct contact.

[0003] General-purpose stacking machines are unsuitable for small-batch stacking needs in experimental settings due to their high cost, large size, and complex debugging. Therefore, most experimental battery cells are currently stacked manually. However, manual stacking is inefficient, and the stacking quality largely depends on the operator's experience, making it easy to damage the separator and electrodes due to improper operation.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

The sliding groove is divided into a middle section and side sections at both ends of the middle section.

[0032] This invention relates to a manual-assisted stacking machine for experimental applications. The free end of the diaphragm is laid on a base. Electrodes are then manually placed on the free end to avoid direct contact and wear between the electrodes and the base. The electrodes are then secured by a pressure foot. With the assistance of a feeding mechanism and a reversing mechanism, the diaphragm is placed over the electrodes. Compared to manual folding, this method improves folding efficiency. Electrodes of the other polarity are then stacked on top of the diaphragm. At this point, the reversing mechanism is at one end of its travel, ensuring that the horizontal height of the diaphragm to be folded is below the corresponding electrode. This allows the covered diaphragm to lie flat above the corresponding electrode, facilitating subsequent electrode placement and securing with the pressure foot without causing wrinkles in the diaphragm, thus ensuring stacking quality.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0047] Please see Figures 1 to 4This embodiment proposes an experimental manual-assisted stacking machine, which includes a frame 1, a feeding mechanism 2, a base, a reversing mechanism 3, and a pressing mechanism 4. The feeding mechanism 2 is disposed on the frame 1 and is used to output the diaphragm 100. The base and the frame 1 are spaced apart along a first horizontal direction. The free end of the diaphragm 100 is laid on the base, and the base is used to receive the electrode 200, which is stacked on top of the diaphragm 100. The reversing mechanism 3 is slidably disposed on the frame 1 along a second horizontal direction perpendicular to the first horizontal direction. The middle part of the stroke of the mechanism 3 is located above the base, and both ends of the stroke can extend to the outside of the base and are not higher than the base; the pressing mechanism 4 includes a pressing foot 41 located above the base, the pressing foot 41 is used to press down and fix the uppermost electrode 200; wherein, along the output direction of the diaphragm 100, the reversing mechanism 3 is located between the feeding mechanism 2 and the base, and is configured to cover the corresponding electrode 200 with one side edge of the electrode 200 as a fold, so that the diaphragm 100 and multiple electrodes 200 are alternately stacked on the base.

[0048] Understandably, the free end of the diaphragm 100 is laid on the base, and then the electrode 200 is placed manually on the free end to avoid direct contact between the electrode 200 and the base, which would cause wear. Then, the electrode 200 can be fixed by the action of the presser foot 41. Then, with the assistance of the feeding mechanism 2 and the reversing mechanism 3, the diaphragm 100 can be covered on top of the electrode 200. Then, the electrode 200 of the other polarity is stacked on top of the diaphragm 100. At this time, the reversing mechanism 3 is at one end of its stroke, so that the horizontal height of the diaphragm 100 to be folded is below the corresponding electrode 200, so that the covered diaphragm 100 is flat on top of the corresponding electrode 200. This makes it easier to fix the electrode 200 with the presser foot 41 after the electrode 200 is placed, without causing wrinkles in the diaphragm 100, thus ensuring the quality of the stacking.

[0049] In this embodiment, the reversing mechanism 3 includes a reversing bracket 31 and a reversing roller 32. The reversing bracket 31 is slidably disposed on the frame 1 along the second horizontal direction. The reversing roller 32 is disposed on the reversing bracket 31. The length direction of the reversing roller 32 is disposed along the first horizontal direction, and it has a reversing channel for the diaphragm 100 to pass through. It is understandable that after the free end of the diaphragm 100 is output by the feeding mechanism 2, it can be laid on the base through the reversing channel. During the process of the reversing bracket 31 moving from one end of the stroke to the other end, it can drive the diaphragm 100 to cover the electrode 200. For ease of explanation, the bottom electrode 200 is defined as the first electrode 200. After the covering is completed, the second electrode 200 is placed on the diaphragm 100 and fixed by hand. Then the reversing bracket 31 is reset, which can drive the diaphragm 100 to cover the second electrode 200. This process is repeated to complete the stacking of the battery cell. With the assistance of the reversing bracket 31 and the reversing roller 32, the stacking quality and stacking efficiency can be guaranteed.

[0050] The reversing bracket 31 can be moved by the lateral movement module in the prior art or by manual movement during the movement process. It is preferred to move it manually in order to further reduce the experimental cost.

[0051] Correspondingly, the frame 1 is provided with a slide groove 11 for the commutation bracket 31 to slide. The slide groove 11 is divided into a middle section 111 and side sections 112 at both ends of the middle section 111. The middle section 111 is arranged parallel to the top of the base, and both ends of the middle section 111 extend to the outside of the base. The side sections 112 are arranged perpendicular to the middle section 111 and extend to the bottom of the base. It can be understood that after the free end is laid on the base, the commutation bracket 31 is moved to one of the side sections 112. After the electrode 200 is placed, the commutation bracket 31 is moved from one of the side sections 112 to the middle section 111 and moves along the middle section 111, thereby completing the folding of the diaphragm 100. Then it is moved from the middle section 111 to the other side section 112 to facilitate the subsequent folding of the diaphragm 100.

[0052] In this embodiment, the pressing mechanism 4 further includes a first driving part 42 and a second driving part 43. The first driving part 42 is arranged parallel to the base along a first horizontal direction and has a first driving end that reciprocates along the first horizontal direction. The second driving part 43 is disposed at the first driving end and has a second driving end that reciprocates along the vertical direction. The second driving end is connected to the pressing foot 41. It is understood that during the application of the diaphragm 100, in order to ensure that the position of the electrode 200 does not change, it is necessary to ensure that the pressing foot 41 is always in contact with the electrode 200. Therefore, after the diaphragm 100 is covered, the pressing foot 41 needs to be pulled out from between the diaphragm 100 and the electrode 200 with the help of the first driving part 42. Then, under the action of the second driving part 43, the pressing foot 41 can be raised, and under the action of the first driving part 42 and the second driving part 43, the pressing foot 41 can be made to contact the new electrode 200. Among them, the first driving part 42 and the second driving part 43 are preferably linear drive structures such as linear cylinders in the prior art, and no specific limitation is made here.

[0053] Preferably, four pressure feet 41 are provided, each located at one of the four corners of the base. Four first driving units 42 and four second driving units 43 are also provided, each corresponding to one of the pressure feet 41. This arrangement further ensures the stability of the electrode 200 during fixing. Furthermore, since the four pressure feet 41 are located at the four corners of the base, when fixing the electrode 200, it is not necessary for too much of the pressure feet 41 to come into contact with the electrode 200. This ensures sufficient contact between the diaphragm 100 and the electrode 200 during the covering process, thereby further guaranteeing the folding quality of the diaphragm 100.

[0054] Specifically, in the two presser feet 41 located in the second horizontal direction, the side edge of one presser foot 41 facing away from the other presser foot 41 is aligned with the side edge of the electrode 200. This arrangement provides a reference in the second horizontal direction for placing the electrode 200, while the reference in the first horizontal direction is provided by the diaphragm 100, thereby ensuring the accuracy of electrode 200 placement and further improving the stacking quality.

[0055] Specifically, in this embodiment, the four pressure feet 41 are divided into a first pressing unit and a second pressing unit in pairs. The first pressing unit and the second pressing unit are arranged along the second horizontal direction. After the free end of the diaphragm 100 is laid on the base, it is fixed by the four pressure feet 41. Then, the first layer of electrode 200 is placed on the diaphragm 100. At this time, when placing the first layer of electrode 200, the side edges of the two pressure feet 41 in the first pressing unit are used as the reference along the second horizontal direction, and the two sides of the width direction of the diaphragm 100 are used as the reference along the first horizontal direction. This ensures the placement accuracy of the first layer of electrode 200 on the pressure feet. After the diaphragm 100 covers the first layer of electrode 200 with the side edge of the first pressing unit as a crease, the second pressing unit is pulled out. At this time, the stability of the electrode 200 can still be guaranteed under the action of the first pressing unit. Then, the second pressing unit is pressed down onto the diaphragm 100 so that the side edges of the two pressing feet 41 in the second pressing unit are used as the reference along the second horizontal direction, and the two sides of the width direction of the diaphragm 100 are used as the reference along the first horizontal direction to place the second layer of electrode 200. This process is repeated to ensure not only the accuracy of the electrode 200 placement, but also the stability of the other electrode 200.

[0056] Furthermore, the gap between the two second drive units 43 in the second horizontal direction is adjustable. The gap between the two second drive units 43 in the first horizontal direction is also adjustable. This configuration allows the four pressure feet 41 to be adapted to different types of battery cells, thereby meeting various experimental requirements.

[0057] For example, the experimental manual-assisted stacking machine also includes an XY-axis servo moving module 44, where the X direction is a first horizontal direction and the Y direction is a second horizontal direction. The XY-axis servo moving module 44 includes an X-axis moving module and two Y-axis moving modules disposed on the X-axis moving module. Each Y-axis moving module has two moving ends, which are respectively connected to the first driving unit 42. Under the action of the XY-axis servo moving module 44, the positions of the four pressure feet 41 can be precisely adjusted to adapt to different experimental requirements.

[0058] In this embodiment, the feeding mechanism 2 includes a material roller 21, multiple drive rollers 22, tension rollers 23, and guide rollers 24. The material roller 21 is rotatably mounted on the frame 1 and is used to wind up and release the diaphragm 100. The multiple drive rollers 22 are arranged sequentially along the transmission direction of the diaphragm 100, and each drive roller 22 can rotate around its own axis. The tension rollers 23 are slidably mounted on the frame 1 along a preset direction and are used to tension the diaphragm 100 released by the material roller 21 onto each drive roller 22. The guide rollers 24 are located downstream of the last drive roller 22 and have a guide channel through which the diaphragm 100 passes. Understandably, the tensioning roller 23 slides on the frame 1 under the action of a linear drive structure such as a cylinder, thereby keeping the entire diaphragm 100 in a tensioned state to ensure that the diaphragm 100 does not wrinkle during the folding process, thus ensuring the quality of the stacked sheets. Under the guidance channel of the guide roller 24, the diaphragm 100 can be limited during the movement of the reversing bracket 31, thereby preventing the diaphragm 100 from separating from the drive roller 22, and further ensuring the quality of the stacked sheets.

[0059] Preferably, the guide rollers 24 and the drive rollers 22 at the end are arranged vertically. This arrangement ensures that the tension experienced by the diaphragm 100 during output is always perpendicular to the tangent of the guide rollers 24, thereby avoiding tension concentration in the diaphragm 100 due to angular deviation and preventing stretching deformation of the diaphragm 100.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
