Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a material feeding device. Background Art

[0002] There are various ways to connect the tabs of soft-pack lithium-ion batteries, including internal welding and external welding, and the external tab welding method is usually mainly used in the field of power and energy storage batteries. In the actual production and application process, in order to ensure the performance and safety of the battery, the battery cell will undergo a series of complex chemical reactions during the formation process, and these reactions will produce a certain amount of gas. In order to effectively discharge these gases, the battery cell needs to be vacuumed and exhausted in the second sealing process. However, in this process, the external tabs of the battery cell often bend and deform to a certain extent due to the pressure difference of vacuuming. This deformation will have a negative impact in the second sealing blanking link, and it is very easy to cause the battery cell tabs to be hit or scratched during the blanking process, which will cause structural damage to the battery cell or even scrap it. This problem not only affects the production efficiency of the battery, but also increases production costs and quality risks.

[0003] In the prior art, in order to solve the above problems, the cell tabs are often shaped after the formation process, for example, by rolling the tabs with a roller. However, rolling the tabs still cannot avoid the bruises and scratches of the deformed tabs, and complicates the production process, resulting in reduced production efficiency and increased production costs.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] The following is based on the attached Figure 1 To Attachment Figure 8 The present invention introduces a material unloading device provided by the utility model.

[0041] like Figures 1 to 3 As shown, in this embodiment, the unloading device includes a unloading fixture 1 and a unloading container 2. The unloading fixture 1 can move the soft-pack battery cells 3, and the unloading container 2 can arrange and accommodate the soft-pack battery cells 3 to facilitate the subsequent batch transfer of the soft-pack battery cells 3.

[0042] Specifically, Figure 1 , Figure 2 As shown, the blanking fixture 1 includes a first fixing mechanism 12 and a second fixing mechanism 15, wherein the first fixing mechanism 12 is used to fix the body 31 of the soft-pack battery cell 3, and the second fixing mechanism 15 is used to fix the tab 32 of the soft-pack battery cell 3. When the blanking fixture 1 is moved, the first fixing mechanism 12 and the second fixing mechanism 15 can move synchronously to transfer the soft-pack battery cell 3. Through the first fixing mechanism 12 and the second fixing mechanism 15, the tab 32 can maintain a fixed posture during the movement, and the distance and angle between the tab 32 and the body 31 remain unchanged.

[0043] like Figure 3As shown, the unloading container 2 includes at least two limiting members 21, and the limiting member 21 has a first limiting portion 211 and a second limiting portion 212. A first limiting space 201 is defined between the first limiting portions 211 of two adjacent limiting members 21, and a second limiting space 202 is defined between the second limiting portions 212 of two adjacent limiting members 21, and a tab accommodation space 203 is also provided on the side of the second limiting portion 212 away from the first limiting portion 211. The first limiting space 201 can be formed along the thickness direction of the soft-pack battery cell 3 (such as Figure 1 , Figure 3 The second limiting space 202 can limit the accommodating body portion 31 along the thickness direction of the soft-pack battery cell 3, and the second limiting space 202 can limit the accommodating sealing portion 33 of the soft-pack battery cell 3. The tab accommodating space 203 can accommodate the tab 32 to prevent the tab 32 from colliding with or scratching other structures in the feeding container 2. Exemplarily, the feeding container 2 also includes a accommodating box 22, at least two limiting members 21 are arranged in the accommodating box 22, and the inner wall of the accommodating box 22 and the second limiting portion 212 are spaced apart to form the tab accommodating space 203.

[0044] like Figure 2 , Figure 3 As shown, the sealing portion 33 is connected between the body portion 31 and the tab 32 of the soft-pack battery cell 3. When the soft-pack battery cell 3 is placed between two adjacent limiting members 21, the sealing portion 33 is limited by the second limiting space 202, so that the tab 32 can be further limited after the second fixing mechanism 15 is separated from the tab 32, so as to prevent the tab 32 from bending at a large angle in the tab accommodating space 203, thereby preventing the tab 32 from colliding with the blanking fixture 1 or the tab 32 when it is placed next time after bending.

[0045] Through the unloading fixture 1, the main body 31 and the tab 32 of the soft-pack battery cell 3 can be relatively fixedly moved as a whole, and properly moved into the unloading container 2, and the first limiting space 201, the second limiting space 202 and the tab accommodating space 203 are used to limit the soft-pack battery cell 3 to avoid the tab 32 from being hit or scratched, so that the unloading device can position and protect the tab 32 during the entire process of moving and storing the soft-pack battery cell 3, avoiding the tab 32 from being hit or scratched after deformation. At the same time, the unloading device has a simple structure and avoids the additional shaping process of the tab 32, which will not complicate the existing production process, thus ensuring production efficiency and production costs.

[0046] In this embodiment, the unloading device further comprises a manipulator, which is connected to the unloading fixture 1 and can drive the unloading fixture 1 to unload the material along the width direction of the tab 32 (such as Figures 1 to 3The material clamp 1 is moved in the Z-axis direction as shown in the figure, thereby placing the soft-pack battery cell 3 between two connected limiters 21. Optionally, in some other embodiments, a driving component can be used to be connected to the blanking fixture 1 and drive the blanking fixture 1 to move. Specifically, the driving component can be a linear module, a cylinder, a motor, etc., all of which are within the scope of protection of the utility model.

[0047] like Figure 4 As shown, in this embodiment, the blanking fixture 1 includes a first driving member 11, which can drive the first fixing mechanism 12 to move, so that the first fixing mechanism 12 can move synchronously with the second fixing mechanism 15, or can move independently, thereby facilitating the adjustment of the relative distance between the first fixing mechanism 12 and the second fixing mechanism 15, so that the blanking fixture 1 can be suitable for a variety of soft-pack battery cells 3, and the first fixing mechanism 12 and the second fixing mechanism 15 can choose a variety of different ways to correspond to fix the main body 31 and the pole ear 32.

[0048] For example, in this embodiment, the first driving member 11 can move the first fixing mechanism 12 along the thickness direction of the soft-pack battery cell 3. When the tab 32 is arranged toward one side of the soft-pack battery cell 3 along the thickness direction of the soft-pack battery cell 3, the distance between the first fixing mechanism 12 and the second fixing mechanism 15 along the thickness direction of the soft-pack battery cell 3 can be adjusted by the first driving member 11, so that the first fixing mechanism 12 and the second fixing mechanism 15 can respectively firmly and accurately fix the body portion 31 and the tab 32. Typically, in some embodiments, when the first fixing mechanism 12 and the second fixing mechanism 15 both adopt parallel clamps to clamp and fix the main body 31 and the tab 32, through the adjustment of the first driving member 11, it is possible to adapt to the different distances between the main body 31 and the tab 32 of different soft-pack battery cells 3 along the thickness direction, so that the first fixing mechanism 12 can clamp the main body 31 in the center, and the second fixing mechanism 15 can clamp the tab 32 in the center, thereby avoiding the phenomenon of pulling between the tab 32 and the main body 31 due to the inappropriate distance between the first fixing mechanism 12 and the second fixing mechanism 15 during clamping.

[0049] In this embodiment, if Figure 4 , Figure 5As shown, the first fixing mechanism 12 includes an adsorption component 121 and a first bracket 122, the adsorption component 121 is mounted on the first bracket 122, the first bracket 122 is movably mounted on the manipulator, and is transmission-connected to the first driving member 11. The first driving member 11 is fixedly mounted on the manipulator. Under the drive of the first driving member 11, the first fixing mechanism 12 can move from one side of the soft-packed battery cell 3 toward the soft-packed battery cell 3, and is adsorbed and fixed when the suction cup in the adsorption component 121 contacts the surface of the soft-packed battery cell 3. It can be understood that the adsorption method can facilitate the fixing of the main body 31, and because it is only adsorbed on one side of the soft-packed battery cell 3 when taking and placing, it is beneficial to avoid the first fixing mechanism 12 from interfering with other soft-packed batteries 3 placed in the unloading container 2 during placement, which can not only avoid collisions with other soft-packed batteries 3 placed in the unloading container 2, but also enable more soft-packed batteries 3 to be arranged in the unloading container 2 with a higher arrangement density, thereby reducing the frequency of replacement or emptying of the unloading container 2 and simplifying the unloading procedure.

[0050] The second fixing mechanism 15 includes a clamping assembly 151 and a second bracket 152. The clamping assembly 151 includes a pair of clips 1511 and a clamping drive (not shown in the figure). The clip 1511 is movably mounted on the second bracket 152. The clamping drive can be a cylinder, a motor, etc., which is fixedly mounted on the second bracket 152 and is connected to the clip 1511. Driven by the clamping drive, the clip 1511 can move toward each other along the thickness direction of the soft-pack battery cell 3 to clamp and fix the pole ear 32, and the clip 1511 can extend into the pole ear accommodating space 203. Compared with other methods such as adsorption fixation, clamping fixation can fix the pole ear 32 more stably and firmly. The clip 1511 not only protects the pole ear 32, but also avoids direct collision between other structures and the pole ear 32. At the same time, compared with other methods such as adsorption fixation, even if the pole ear 32 has been deformed, as long as the pole ear 32 can enter between the two clips 1511, the pole ear 32 can be clamped and fixed by the two clips 1511 moving towards each other, which has a more stable and efficient fixation success rate and can play a certain shaping role on the pole ear 32.

[0051] When taking the soft-pack battery cell 3, after the unloading fixture 1 is moved to the top of the soft-pack battery cell 3 and the second fixing mechanism 15 is located above the pole ear 32, the unloading fixture 1 can be driven down by the manipulator so that the pole ear 32 enters between the two opened clips 1511, and then the clips 1511 are closed to clamp and fix the pole ear 32. In addition, before the manipulator drives the unloading fixture 1 to descend, the adsorption component 121 can be moved in a direction away from the soft-pack battery cell 3 by the first driving member 11 to avoid interference between the adsorption component 121 and the main body 31. When the manipulator drives the unloading fixture 1 to descend to the position, that is, after the pole ear 32 enters between the two clips 1511, the adsorption component 121 is moved in a direction close to the soft-pack battery cell 3 by the first driving member 11, so that the suction cup of the adsorption component 121 can be attached to the surface of the soft-pack battery cell 3, thereby achieving adsorption and fixation.

[0052] Furthermore, the blanking fixture 1 further includes a second driving member 14, which is fixedly mounted on the manipulator and is transmission-connected to the second bracket 152, and the second bracket 152 is movably mounted on the manipulator. Under the drive of the second driving member 14, the second fixing mechanism 15 can move along the length direction of the tab 32 (refer to Figure 1 , Figure 2 The blanking fixture 1 moves in the Y-axis direction (as shown in FIG. 1 ) so that the blanking fixture 1 can be suitable for soft-pack batteries 3 having main bodies 31 or sealing parts 33 of different lengths.

[0053] Specifically, when in use, the material unloading fixture 1 can be moved to the top of the soft-pack battery cell 3, and the unloading fixture 1 can be driven down by the manipulator to make the adsorption component 121 drop to the same horizontal position as the main body 31. Before the drop, the second bracket 152 is moved by the second driving member 14 so that the second bracket 152 is away from the adsorption component 121, which can prevent the second fixing mechanism 15 from interfering with other structures. Then, the adsorption component 121 is moved by the manipulator or the first driving member 11 so that the adsorption component 121 moves in a direction close to the soft-pack battery cell 3, so that the suction cup of the adsorption component 121 can be attached to the surface of the soft-pack battery cell 3, thereby achieving adsorption fixation. After adsorption and fixation, the entire unloading fixture 1 is lifted until there is no risk of collision on the moving route of the second fixing mechanism 15, and then the second fixing mechanism 15 is moved by the second driving member 14 to move toward the pole lug 32 along the length direction of the pole lug 32 until the pole lug 32 enters between the two clamps 1511, and then the clamps 1511 are closed to clamp and fix the pole lug 32. After clamping and fixing, the body 31 and the pole lug 32 of the soft-pack battery cell 3 can be relatively fixed and moved as a whole, and properly moved into the unloading container 2 to avoid collision or scratching of the pole lug 32.

[0054] Of course, in some embodiments, only the first drive member 11 may be provided, or only the second drive member 14 may be provided. Moreover, the first drive member 11 and the second drive member 14 may be selected from either a cylinder or a motor. In the present utility model, whether to provide the first drive member 11 or the second drive member 14, and the specific structure of the first drive member 11 or the second drive member 14 are not limited, as long as the fixation of the soft-pack battery cell 3 can be satisfied. Therefore, depending on the different operating modes of the manipulator or the drive assembly, and whether the first drive member 11 or the second drive member 14 is provided, the unloading device can be moved in different ways to achieve the overall movement of the main body 31 and the pole ear 32, and form a better protection effect on the pole ear 32, all of which are within the scope of protection of the present utility model.

[0055] Preferably, in this embodiment, the blanking fixture 1 further includes a first slide rail 13. The first slide rail 13 is mounted on the manipulator or the driving component and is extended along the thickness direction of the soft-pack battery cell 3. The first bracket 122 is slidably connected to the first slide rail 13 and can slide along the thickness direction of the soft-pack battery cell 3 under the drive of the first driving member 11 to adjust the position of the adsorption component 121. Through the first slide rail 13, the process of adjusting the adsorption component 121 can be made more stable and convenient.

[0056] Furthermore, the first slide rail 13 has a dovetail protrusion, the first bracket 122 has a dovetail groove, and the dovetail protrusion is slidably connected with the dovetail groove. During the sliding process, the weight of the first fixing mechanism 12 is carried by the manipulator or the driving component through the dovetail groove and the dovetail protrusion, thereby reducing the workload of the first driving member 11, which is conducive to selecting the first driving member 11 with a smaller rated load, thereby reducing the weight of the entire blanking fixture 1.

[0057] Similarly, the blanking fixture 1 also includes a second slide rail 16. The second slide rail 16 is installed on the manipulator or the driving component and extends along the length direction of the pole ear 32. The second bracket 152 is slidably connected to the second slide rail 16, and can slide along the thickness direction of the soft-pack battery cell 3 under the drive of the second driving member 14 to adjust the position of the adsorption component 121. Through the second slide rail 16, the process of adjusting the adsorption component 121 can be made more stable and convenient.

[0058] Furthermore, the second slide rail 16 also has a dovetail protrusion, and the second bracket 152 also has a dovetail groove, and the dovetail protrusion is slidably connected with the dovetail groove. During the sliding process, the weight of the second fixing mechanism 15 is carried by the manipulator or the driving component through the dovetail groove and the dovetail protrusion, thereby reducing the workload of the second driving member 14, which is conducive to selecting a second driving member 14 with a smaller rated load, thereby reducing the weight of the entire blanking fixture 1.

[0059] Optionally, in some other embodiments, the dovetail groove may be provided on the first slide rail 13 or the second slide rail 16, and the dovetail protrusion may be correspondingly provided on the first bracket 122 or the second bracket 152, which may also achieve the above-mentioned effect of reducing the workload and is also within the scope of protection of the present utility model.

[0060] like Figures 6 to 8 As shown, in this embodiment, the limiting member 21 is plate-shaped and can be arranged in the accommodating box 22 in a vertical direction to form the above-mentioned first limiting space 201 and the second limiting space 202 between two adjacent limiting members 21. The thickness of the first limiting portion 211 is less than the thickness of the second limiting portion 212, so that the width of the first limiting space 201 is greater than the width of the second limiting space 202, so that the first limiting space 201 can limit the body portion 31 with a larger thickness, and the second limiting space 202 can limit the sealing portion 33 with a smaller thickness.

[0061] like Figure 8 As shown, the first limiting portion 211 is provided with an avoidance notch 2110, and the avoidance notch 2110 is used to avoid the adsorption component 121 when the clip 1511 extends into the tab accommodation space 203, so that when the first fixing mechanism 12 is sequentially put in or taken out along the arrangement direction of the limiting member 21, it can go deep into the accommodation box 22 to avoid the phenomenon of throwing the soft-pack battery cell 3 between the limiting members 21, which can reduce the falling distance of the soft-pack battery cell 3 and avoid damage to the soft-pack battery cell 3. Optionally, in some other embodiments, a accommodating frame can be used or the limiting members 21 can be directly arranged and arranged, as long as there is enough space on the side of the limiting member 21 to form the tab accommodation space 203, it belongs to the scope to be protected by the present utility model.

[0062] In this embodiment, if Figure 7 As shown, two limiting members 21 form a pair, and the first limiting space 201 and the second limiting space 202 are formed between each pair of limiting members 21. In some other embodiments, the first limiting space 201 and the second limiting space 202 can be formed between any two adjacent limiting members 21. The utility model does not make specific restrictions on this, as long as the limiting of the main body 31 and the sealing part 33 of the soft-pack battery cell 3 can be achieved.

[0063] It should be noted that in the above-mentioned embodiments, the unloading device provided by the utility model is introduced by taking the soft-pack battery cell 3 with the pole ear 32 on the same side as an example. In some other embodiments, for the soft-pack battery cell 3 with the pole ear 32 on the opposite side (that is, the pole ear 32 is provided on one side and the other side of the soft-pack battery cell 3), by adding another second fixing mechanism 15 in the unloading device, the main body 31 and the pole ears 32 on both sides of the main body 31 can be clamped and fixed, and by placing the limiter 21 in the middle of the accommodating box 22, the above-mentioned pole ear accommodating space 203 is formed on both sides of the limiter 21, so that the pole ears 32 on both sides can be prevented from being hit or scratched, so that the unloading device can position and protect the pole ears 32 during the whole process of moving and storing the soft-pack battery cell 3, and avoid the phenomenon of collision and scratching of the pole ears 32 after deformation.

[0064] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
