Description

Technical Field

[0001] This utility model relates to the field of energy storage product technology, and more specifically, to a core loading device and a battery production line equipped with the same. Background Technology

[0002] In the assembly process of cylindrical batteries, cylindrical cores need to be inserted into a steel casing. Currently, the insertion of cylindrical cores into the casing is often achieved through automated assembly lines. However, in the automated assembly process of cylindrical cores, before the cores are inserted into the casing, they need to be inspected by a go-gauge assembly. If an defective core diameter is detected, the core will be gripped out by the go-gauge grippers, and the gripped core must be manually inserted into the casing.

[0003] However, during the manual insertion of defective cores gripped by the go-go gauge jaws, workers found that the vast majority of cores did not exhibit any difficulty in fitting into the steel casing and could be inserted smoothly. This is because the go-go gauge assembly typically has stringent inspection standards to ensure 100% successful insertion during the casing process, thus preventing machine downtime. Therefore, while most cores can be successfully inserted into the steel casing manually, manual insertion is often inefficient and wastes significant manpower, making it difficult to handle defective cores in the current technology. Utility Model Content

[0004] The main objective of this invention is to provide a core insertion device and a battery production line equipped with it, so as to solve the problem in the prior art that it is inconvenient to insert cores with poor diameter into the casing.

[0005] To achieve the above objectives, according to one aspect of the present invention, a core insertion device is provided, comprising:

[0006] A shaping mechanism includes a first housing and a second housing, at least one of which is movably disposed. The first housing and the second housing can be spliced ​​together to form a shaping cavity when spliced. The shaping cavity has a shaping inlet and a shaping outlet that is adapted to the inner diameter of the part to be assembled. The shaping cavity is funnel-shaped and the diameter of the shaping cavity gradually decreases along the direction from the shaping inlet to the shaping outlet.

[0007] The transfer mechanism is movably installed and is used to transfer the core to the shaping cavity and shape the core through the shaping outlet.

[0008] Furthermore, when the first and second shells are joined together, a sleeve cavity is formed that communicates with the shaping cavity. The sleeve cavity is located on the side of the shaping outlet away from the shaping cavity, and the diameter of the sleeve cavity is adapted to the outer diameter of the part to be assembled.

[0009] Furthermore, the component to be installed is a battery casing, and the diameter of the shaping outlet is equal to the inner diameter of the component to be installed; wherein, the shaping cavity forms a limiting step with the sleeve cavity at the position of the shaping outlet, so that the component to be installed abuts against the limiting step.

[0010] Furthermore, a first guide protrusion is provided on the first housing, and a second guide protrusion is provided on the second housing; both the first guide protrusion and the second guide protrusion are located inside the shaping cavity and are used to be positioned above the part to be assembled.

[0011] In particular, along the extension direction from the shaping inlet to the shaping outlet, the protrusion height of at least one of the first guide protrusion and the second guide protrusion gradually increases, and the first guide protrusion and the second guide protrusion are used to form the shaping outlet.

[0012] Furthermore, the first shell includes a first conical shell segment and a first cylindrical shell segment connected to each other, and the second shell includes a second conical shell segment and a second cylindrical shell segment connected to each other;

[0013] In this configuration, the end of the first conical shell segment near the first cylindrical shell segment and the end of the second conical shell segment near the second cylindrical shell segment form a shaping outlet; the first and second cylindrical shell segments are joined together to fit onto the component to be assembled; or,

[0014] A first guide protrusion is provided on the side of the first cylindrical shell section near the first conical shell section, and a second guide protrusion is provided on the side of the second cylindrical shell section near the second conical shell section. Along the extension direction from the shaping inlet to the shaping outlet, the protrusion height of at least one of the first guide protrusion and the second guide protrusion gradually increases. The first guide protrusion and the second guide protrusion are used to form the shaping outlet. The part of the first cylindrical shell section that extends out of the first guide protrusion and the part of the second cylindrical shell section that extends out of the second guide protrusion are spliced ​​together to be fitted onto the part to be assembled.

[0015] Furthermore, the core insertion device also includes:

[0016] A first driving structure is drivenly connected to the first housing to move the first housing; and / or,

[0017] The second drive structure is driven to connect with the second housing to move the second housing.

[0018] Furthermore, the core insertion device also includes:

[0019] The first transmission component is connected to the first housing and the first drive structure to drive the first housing to move;

[0020] The second transmission component is connected to the second housing and the second drive structure to drive the second housing to move;

[0021] The first transmission component is detachably connected to the first housing; and / or the second transmission component is detachably connected to the second housing.

[0022] Furthermore, the core insertion device includes multiple shaping mechanisms, multiple transfer mechanisms, multiple first transmission components, and multiple second transmission components.

The multiple shaping mechanisms, multiple transfer mechanisms, multiple first transmission components, and multiple second transmission components are arranged in a one-to-one correspondence.

[0023] In this configuration, multiple first transmission components are spaced apart on the drive end of the first drive structure, and multiple second transmission components are spaced apart on the drive end of the second drive structure.

[0024] Furthermore, the transfer mechanism includes a clamping member and a pushing member. The clamping member is used to clamp the core, and the pushing member is movably disposed to abut against the core to push the core to move.

[0025] According to one aspect of the present invention, a battery production line is provided, including the aforementioned core loading device.

[0026] By applying the technical solution of this utility model, since the diameter of the shaping cavity gradually decreases along the direction from the shaping inlet to the shaping outlet, if the diameter of the winding core is large at a certain position during its passage through the first shaping cavity, the shaping cavity can compress that position and limit the diameter of the winding core at that point to the size of the shaping outlet. This allows for adjustment of the winding core's size, and the winding core can then be loaded into the battery casing via a transfer mechanism. Therefore, this application solves the problem in the prior art of inconveniently loading winding cores with unsuitable diameters into the casing. Attached Figure Description

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 4 As shown, one embodiment of this utility model provides a core loading device, including a shaping mechanism 10 and a transfer mechanism 20. The shaping mechanism 10 includes a first housing 11 and a second housing 12, at least one of which is movably disposed. The first housing 11 and the second housing 12 can be spliced ​​together to form a shaping cavity. The shaping cavity has a shaping inlet 131 and a shaping outlet 132 adapted to the inner diameter of the component 200 to be loaded. The shaping cavity is funnel-shaped, and its diameter gradually decreases along the direction from the shaping inlet 131 to the shaping outlet 132. The transfer mechanism 20 is movably disposed and is used to transfer the core 100 into the shaping cavity and shape the core 100 through the shaping outlet 132.

[0039] Using the core-insertion device provided in this embodiment, since the diameter of the shaping cavity gradually decreases along the direction from the shaping inlet 131 to the shaping outlet 132, if the diameter of the core 100 is large at a certain position during its passage through the first shaping cavity, the shaping cavity can compress that position and limit the diameter of the core 100 at that point to the size of the shaping outlet 132. This allows for adjustment of the core 100's dimensions, and the core 100 is then inserted into the battery casing via the transfer mechanism 20. Furthermore, as the diameter of the shaping cavity gradually decreases along the direction from the shaping inlet 131 to the shaping outlet 132 during the core 100's passage, it guides the movement of the core 100, and the shaping process of the core 100 is gradual, thus preventing deformation of the core 100.

[0040] In this embodiment, when the first housing 11 and the second housing 12 are joined, a fitting cavity 14 communicating with the shaping cavity is formed. The fitting cavity 14 is located on the side of the shaping outlet 132 away from the shaping cavity, and the diameter of the fitting cavity 14 is adapted to the outer diameter of the component to be assembled 200. Specifically, the component to be assembled 200 is a battery housing. In this way, when the core 100 is shaped by the shaping mechanism 10, the core 100 can directly enter the battery housing fitted in the fitting cavity 14 after leaving the shaping cavity from the shaping outlet 132, thereby completing the process of inserting the core 100 into the housing.

[0041] In this embodiment, the component to be assembled 200 is a battery casing. The diameter of the shaping outlet 132 is equal to the inner diameter of the component to be assembled 200. The shaping cavity forms a limiting step with the fitting cavity 14 at the position of the shaping outlet 132, so that the component to be assembled 200 abuts against the limiting step. In this way, the core 100 can enter the battery casing without obstruction when it leaves the shaping outlet 132, thereby ensuring that the process of the core 100 entering the casing is not interrupted, thus ensuring the efficiency of the core 100 entering the casing. Furthermore, the limiting step formed by the shaping cavity and the fitting cavity 14 can abut against the component to be assembled 200, thereby ensuring the stability of the fitting cavity 14.

[0042] Specifically, "the diameter of the shaping outlet 132 is equal to the inner diameter of the part to be installed 200" means that the diameter of the shaping outlet 132 is basically equal to the inner diameter of the part to be installed 200. The diameter of the shaping outlet 132 can also be slightly smaller than the inner diameter of the part to be installed 200. For example, the diameter of the shaping outlet 132 can be less than 2mm smaller than the inner diameter of the part to be installed 200.

[0043] Specifically, the fact that "the diameter of the shaping outlet 132 is equal to the inner diameter of the part to be installed 200" can be achieved by reducing the wall thickness of the first housing 11 and the second housing 12 at the sleeve cavity 14.

[0044] In this embodiment, a first guide protrusion is provided on the first housing 11, and a second guide protrusion is provided on the second housing 12. Both the first and second guide protrusions are located within the shaping cavity and are positioned above the component to be assembled 200. Along the extending direction from the shaping inlet 131 to the shaping outlet 132, the protrusion height of at least one of the first and second guide protrusions gradually increases, forming the shaping outlet 132. This allows for further shaping of the core 100 by the first and second guide protrusions, and guides the core 100 into the component to be assembled 200, thereby significantly improving the smoothness of the core 100 entering the sleeve component.

[0045] In this embodiment, the first housing 11 includes a first conical shell segment 111 and a first cylindrical shell segment 112 connected to each other, and the second housing 12 includes a second conical shell segment 121 and a second cylindrical shell segment 122 connected to each other.

[0046] In one embodiment, the end of the first conical shell segment 111 near the first cylindrical shell segment 112 and the end of the second conical shell segment 121 near the second cylindrical shell segment 122 form a shaping outlet 132. The first cylindrical shell segment 112 and the second cylindrical shell segment 122 are joined together to fit onto the part to be assembled 200. Thus, the first conical shell segment 111 and the second conical shell segment 121 can be joined to form a shaping cavity, and the first cylindrical shell segment 112 and the second cylindrical shell segment 122 can be joined to form a fitting portion, thereby allowing the part to be assembled 200 to be fitted onto the first shell 11 and the second shell 12 when they are close together. Therefore, the first shell 11 and the second shell 12 can be used to shape the core 100, ensuring the convenience of inserting the core 100 into the shell.

[0047] In another embodiment, a first guide protrusion is provided on the side of the first cylindrical shell segment 112 near the first conical shell segment 111, and a second guide protrusion is provided on the side of the second cylindrical shell segment 122 near the second conical shell segment 121. Along the extension direction from the shaping inlet 131 to the shaping outlet 132, the height of at least one of the first and second guide protrusions gradually increases. The first and second guide protrusions form the shaping outlet 132. The portion of the first cylindrical shell segment 112 extending from the first guide protrusion and the portion of the second cylindrical shell segment 122 extending from the second guide protrusion are joined together to fit onto the component to be assembled 200. In this way, the first and second guide protrusions guide the insertion process of the core 100 into the shell, and allow the component to be assembled 200 to abut against the first and second protrusions, thereby preventing the component to be assembled 200 from directly entering the shaping cavity and ensuring that the core 100 can accurately enter the component to be assembled 200.

[0048] In this embodiment, the core insertion device further includes a first driving structure, which is drivenly connected to the first housing 11 to move the first housing 11. This allows the first housing 11 to move closer to or further away from the second housing 12 via the first driving structure, facilitating the formation of a sleeve portion between the first housing 11 and the second housing 12 to accommodate the accessory 200. After the core 100 is inserted into the housing, the device avoids the accessory 200, allowing for easy separation of the sleeved accessory from the core 100.

[0049] In this embodiment, the core insertion device further includes a second driving structure, which is drivenly connected to the second housing 12 to move the second housing 12. This allows the second housing 12 to move closer to or further away from the first housing 11 via the second driving structure, facilitating the formation of a sleeve portion between the first housing 11 and the second housing 12 to accommodate the accessory 200. After the core 100 is inserted into the housing, the device avoids the accessory 200, facilitating the separation of the sleeved accessory from the core 100.

[0050] In this embodiment, the core insertion device further includes a first transmission member 31 and a second transmission member 32. The first transmission member 31 is connected to the first housing 11 and the first drive structure so that the first drive structure drives the first housing 11 to move through the first transmission member 31. The second transmission member 32 is connected to the second housing 12 and the second drive structure so that the second drive structure drives the second housing 12 to move through the second transmission member 32.

[0051] Specifically, the core insertion device also includes a transmission structure 30, which includes a first transmission member 31 and a second transmission member 32.

[0052] Specifically, the first transmission member 31 may be a rod-shaped structure, with its two ends connected to the first driving structure and the first housing 11, respectively.

[0053] Specifically, the second transmission member 32 can be a rod-shaped structure, with its two ends connected to the second drive structure and the second housing 12, respectively.

[0054] Specifically, the first drive structure and the second drive structure can be two drive parts of the same drive device.

[0055] Optionally, the first transmission component 31 is detachably connected to the first housing 11. In this way, if the first housing 11 is damaged, the damaged first housing 11 can be replaced; or, if the model of the core 100 to be inserted changes, the size of the first housing 11 can be adjusted accordingly to adapt to different usage requirements, thereby improving the adaptability of the core insertion device.

[0056] Optionally, the second transmission member 32 is detachably connected to the second housing 12. In this way, if the second housing 12 is damaged, the damaged second housing 12 can be replaced; or, if the model of the core 100 to be inserted changes, the size of the second housing 12 can be adjusted accordingly to adapt to different usage requirements, thereby improving the adaptability of the core insertion device.

[0057] In this embodiment, the core insertion device includes multiple shaping mechanisms 10, multiple transfer mechanisms 20, multiple first transmission components 31, and multiple second transmission components 32, which are arranged in a one-to-one correspondence. The multiple first transmission components 31 are spaced apart on the drive end of the first drive structure, and the multiple second transmission components 32 are spaced apart on the drive end of the second drive structure. This allows multiple first housings 11 and second housings 12 to move simultaneously via the drive ends of the first and second drive structures. Furthermore, multiple transfer mechanisms 20 are provided, enabling the simultaneous insertion of multiple cores 100 into the housing, thus significantly improving the efficiency of core insertion.

[0058] Specifically, the core insertion device includes a first drive rod 33 and a second drive rod 34. The first drive rod 33 forms the drive end of the first drive structure, and the second drive rod 34 forms the drive end of the second drive structure.

[0059] In this embodiment, the transfer mechanism 20 includes a clamping member 21 and a pushing member 22. The clamping member 21 is used to clamp the core 100, and the pushing member 22 is movably disposed and used to abut against the core 100 to push the core 100 to move. Thus, the core 100 can be clamped and positioned by the clamping member 21, and the core 100 can be moved by the pushing member 22, thereby providing power for the movement of the core 100 within the shaping cavity. Specifically, during the process of the core 100 entering the housing, when the diameter of the core 100 is large, the pushing member 22 can push the core 100 to move, ensuring that the core 100 can move smoothly within the shaping cavity and complete the shaping of the core 100.

[0060] Specifically, the clamping member 21 includes a first clamping plate 211 and a second clamping plate 212 spaced apart. The first clamping plate 211 and the second clamping plate 212 are movably arranged close to or away from the other of the first clamping plate 211 and the second clamping plate 212.

[0061] Specifically, the pusher 22 includes a push rod 221 and an abutment plate 222 connected to each other. The push rod 221 is movably configured to drive the abutment plate 222 to push the core 100 to move.

[0062] Another embodiment of this utility model provides a battery production line, including the aforementioned core loading device.

[0063] Specifically, the battery production line also includes a loading trolley, a loading device, a padding device, a flipping device, and a cell positioning device. The process of the core 100 entering the battery casing on the battery production line is as follows:

[0064] 1. After loading the pre-loaded coil cores with defective diameter 100 (negative end facing up) into the loading trolley, push the trolley into the loading area;

[0065] 2. The feeding device grabs a row of cores 100 and puts them into the cup. After the positioning process, the cell positioning device will rotate the cores 100 to ensure that the tabs of each core 100 are in the same direction.

[0066] 3. After the upper shim device installs the shim on each core 100, the tab bending device bends the negative tab into place.

[0067] 4. The flipping device flips the core 100 with the gasket installed so that its positive terminal faces upward;

[0068] 6. The cell positioning device will rotate and position the core 100 to ensure that the tabs of each core 100 are in the same direction. Then the shim device will install the shims on the core 100. At the same time, cores 100 with abnormal shim installation will be discharged.

[0069] 7. The core 100 is shaped and inserted into the shell by the transfer mechanism 20 and the shaping mechanism 10.

[0070] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: They solve the problem of "diameter defective" cores 100 being rejected during the casing process of cylindrical battery cores 100 due to slight deformation of the cores 100 and strict dimensional standards of the assembly line. Through the forced shaping effect of the positioning funnel (i.e., the shaping mechanism 10) on the diameter and shape of the cores 100, the cores 100 are more easily installed into the steel casing (battery casing). Furthermore, multiple units of this device can be connected in series to install multiple cores 100 at once. Compared with traditional manual casing installation, automatic casing installation greatly improves production efficiency and reduces labor costs.
