[0026] a. Battery. Detailed Implementation

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] This utility model embodiment provides an electro-precision edge trimming device, such as... Figure 1 As shown, the electro-precision edge trimming device includes a placement platform 110, a pushing mechanism 120, an elastic pressing mechanism 130, and an edge trimming mechanism 140.

[0029] The placement platform 110 is used to place the battery a to be cut, and the placement platform 110 is provided with a positioning baffle 111.

[0030] The pushing mechanism 120 is used to push the battery a so that the side of the edge to be cut abuts against the positioning baffle 111.

[0031] The elastic pressing mechanism 130 is used to elastically press the battery a against the placement platform 110 during the process of the pushing mechanism 120 pushing the battery a. The elastic pressing mechanism 130 works in coordination with the pushing mechanism 120 to position the battery a to be cut on the placement platform 110.

[0032] The edge-cutting mechanism 140 is located at the edge-cutting station. The edge-cutting mechanism 140 is used to cut off the side of the battery a positioned on the placement platform 110.

[0033] The electro-precision edge trimming device of this application embodiment uses a placement platform 110 with a positioning baffle 111. A pushing mechanism 120 is used to push the battery a so that its side abuts against the positioning baffle 111. During the process of the pushing mechanism 120 pushing the battery a, the elastic pressing mechanism 130 elastically presses the battery a against the placement platform 110, which can prevent the pushing mechanism 120 from tilting the battery a during the positioning process, thus achieving precise positioning. This ensures that after the edge trimming mechanism 140 trims the battery a positioned on the placement platform 110, the remaining amount is stable and consistent, improving the quality and stability of battery edge trimming. Moreover, the electro-precision edge trimming device of this application does not require manual pressing of the battery a onto the placement platform 110 for positioning, realizing automated edge trimming of the battery a, reducing the degree of manual operation, improving production efficiency, and reducing safety risks.

[0034] The electro-precision trimming device of this application can be applied to multi-station equipment, and can be used in conjunction with other mechanisms on the equipment such as the feeding mechanism to realize the production of battery a, thereby improving the automation level of battery a production.

[0035] The contact surface between the placement platform 110 and battery a can be made of imported epoxy board to prevent scratching battery a.

[0036] refer to Figure 1 and Figure 2In an optional embodiment of this application, the elastic pressing mechanism 130 includes a pressing drive 131, a pressing mounting plate 132, a pressing plate 133, and at least one elastic component 134. The pressing plate 133 is elastically connected to the pressing mounting plate 132 through the elastic component 134. The driving end of the pressing drive 131 is connected to the pressing mounting plate 132 and drives the pressing mounting plate 132 to move, so as to elastically press the battery a onto the placement platform 110 through the pressing plate 133.

[0037] The pressure plate 133 is connected to the pressure mounting plate 132 through the elastic component 134. This elastic connection method allows the pressure plate 133 to have a certain elastic buffering effect when pressing the battery a. Together with the pressure driving component 131, it can output appropriate pressure to ensure that the battery a will not tilt up during the process of the pushing mechanism 120 pushing the battery a, and the pushing mechanism 120 can push the battery a to the positioning baffle 111 for positioning.

[0038] The driving end of the pressure driving component 131 is connected to the pressure mounting plate 132. By driving the pressure mounting plate 132 to move, the pressure plate 133 is driven to move, thereby achieving elastic pressure on the battery a, so that the battery a can be stably pressed on the placement platform 110, providing a reliable guarantee for the edge cutting operation.

[0039] Therefore, through the coordinated operation of the placement platform 110, the pushing mechanism 120, the elastic pressing mechanism 130, and the cutting mechanism 140, precise cutting of the side of battery a can be achieved, thereby improving the processing quality of battery a and the consistency and stability of the cutting allowance.

[0040] Optionally, the pressure plate 133 can be made of imported epoxy board to avoid scratching the battery a.

[0041] The number of elastic components 134 can be one, two, or more. When one elastic component 134 is provided, it can be positioned centrally on the pressure plate 133. When the pressure plate 133 abuts against the battery a, the output force of the pressure driving member 131 can be distributed relatively evenly on the surface of the battery a. When two elastic components 134 are provided, they are positioned on both sides of the pressure plate 133. When the pressure plate 133 abuts against the battery a, the output force of the pressure driving member 131 can be distributed evenly on the surface of the battery a, preventing the battery a from tilting during the edge positioning process. When two or more elastic components 134 are provided, they can be evenly distributed on the pressure plate 133.

[0042] Preferably, in this embodiment of the application, two elastic components 134 are provided, and the two elastic components 134 are provided on both sides of the pressure plate 133.

[0043] refer to Figure 1 and Figure 2 In an optional embodiment of this application, the elastic component 134 includes a connecting rod 1341, a spring 1342, and a limiting member 1343. One end of the connecting rod 1341 is fixedly connected to the pressure plate 133, and the other end is provided through the pressure mounting plate 132. The spring 1342 is sleeved on the outer periphery of the connecting rod 1341 and located between the pressure mounting plate 132 and the pressure plate 133. The limiting member 1343 is provided on the side of the pressure mounting plate 132 away from the spring 1342, and the limiting member 1343 is fixedly connected to the connecting rod 1341.

[0044] The pressing drive 131 drives the pressing mounting plate 132 to move, and the pressing plate 133 moves accordingly towards the battery a. At this time, the spring 1342 is compressed, generating elastic force, which is transmitted to the pressing plate 133, allowing the pressing plate 133 to press the battery a against the placement platform 110 with a certain elastic force. This elastic pressing method can form a stable contact between the battery a and the placement platform 110, while allowing the battery a to make a small displacement to a certain extent. Combined with the pushing mechanism, this prevents the battery a from tilting during the pushing and positioning process.

[0045] Furthermore, when the edge-cutting mechanism 140 performs the edge-cutting operation, some vibration will be generated. The spring 1342 in the elastic component 134 can play a role in buffering and shock absorption, absorbing some of the vibration energy and reducing the impact of vibration on battery a.

[0046] The function of the limiting member 1343 is to abut against the mounting plate 132 to prevent the mounting plate 132 from disengaging from the connecting rod 1341.

[0047] This application uses a connecting rod 1341, a spring 1342, and a limiting member 1343 to form an elastic component 134, which has a simple structure and is easy to process and install.

[0048] In an optional embodiment of this application, the pressure driving member 131 is a cylinder, and the driving end of the cylinder is connected to the pressure mounting plate 132 to drive the pressure mounting plate 132 to move.

[0049] The cylinder's thrust can be adjusted by regulating the air pressure via its own adjusting screw, providing a stable counterforce. During the trimming process, this stable counterforce ensures tight contact between battery a and the placement platform 110, preventing displacement or vibration of battery a during trimming and improving trimming accuracy and quality. Furthermore, the cylinder's thrust can be flexibly adjusted according to the size, weight, and trimming process requirements of battery a, adapting to the processing of different specifications and types of batteries a.

[0050] In other embodiments, the pressure driving member 131 may also use a motor or other driving component as a power source to drive the pressure mounting plate 132 to move, and in turn drive the pressure plate 133 to move.

[0051] refer to Figure 1 In an optional embodiment of this application, the electro-precision trimming device further includes a platform moving mechanism 150, which is connected to the placement platform 110 and drives the placement platform 110 to move between the loading station and the trimming station.

[0052] By setting up the platform moving mechanism 150, when loading materials, the platform moving mechanism 150 can move the placement platform 110 to the loading station, providing sufficient operating space for the external loading robot to place the battery a to be cut on the placement platform 110; after loading is completed, the platform moving mechanism 150 drives the placement platform 110 to move from the loading station to the cutting station. The elastic pressing mechanism 130 and the pushing mechanism 120 can cooperate to position the battery a on the placement platform 110, and the cutting mechanism 140 on the cutting station performs cutting operation on the side of the battery a.

[0053] refer to Figure 1 In an optional embodiment of this application, the platform moving mechanism 150 includes a translation drive 151, a translation guide rail 152, and a moving plate 153. The translation guide rail 152 is arranged along a first direction. The placement platform 110 is mounted on the moving plate 153. The driving end of the translation drive 151 is connected to the moving plate 153 and drives the moving plate 153 to move along the translation guide rail 152, thereby moving the placement platform 110 between the loading station and the trimming station. The first direction is the X-axis direction as shown in the figure.

[0054] The translation drive component 151 provides power to move the movable plate 153 along the translation guide rail 152. The translation guide rail 152 guides the movement of the movable plate 153, making the movement of the movable plate 153 smoother and improving the accuracy and stability of the movement.

[0055] By setting up a translation drive component 151 to drive the moving plate 153 to move on the translation guide rail 152, the placement platform 110 can be moved between the loading station and the cutting station with a relatively simple structure. The assembly is simple and easy to maintain.

[0056] Optionally, the translation drive 151 can be a cylinder, and the thrust of the cylinder can be adjusted by adjusting the air pressure through its own adjusting screw, which provides high flexibility in use.

[0057] refer to Figure 1 and Figure 2 In an optional embodiment of this application, the edge cutting mechanism 140 includes an upper cutter 141, a lower cutter 142, and an edge cutting drive assembly 143. The drive end of the edge cutting drive assembly 143 is connected to the upper cutter 141 and drives the upper cutter 141 to move closer to or away from the lower cutter 142.

[0058] In practice, after the battery a to be trimmed is positioned on the placement platform 110, the trimming drive assembly 143 drives the upper cutter 141 to move closer to the lower cutter 142. The upper cutter 141 and the lower cutter 142 close together, working together to cut off the side of the battery a. After trimming is completed, the trimming drive assembly 143 reverses its movement, driving the upper cutter 141 away from the lower cutter 142 and returning it to its initial position, ready for the next trimming operation.

[0059] Therefore, by setting up the upper cutter 141, the lower cutter 142, and the edge-cutting drive assembly 143, the positioned battery a can be edge-cut, ensuring the accuracy and consistency of the edge cutting. Furthermore, the moving distance of the upper cutter 141 can be adjusted to adapt to the edge-cutting requirements of various batteries a, providing greater flexibility.

[0060] refer to Figure 1 In an optional embodiment of this application, the electro-precision trimming device further includes a base 160. The trimming drive assembly 143 includes a trimming base plate 1431, a trimming drive member 1432, a trimming mounting plate 1433, and a trimming guide rail 1434. The trimming guide rail 1434 is arranged along a second direction. The upper cutter 141 is mounted on the trimming mounting plate 1433. The trimming base plate 1431 is vertically mounted on the base 160. The trimming drive member 1432 and the trimming guide rail 1434 are both disposed on the trimming base plate 1431. The drive end of the trimming drive member 1432 is connected to the trimming mounting plate 1433 and drives the trimming mounting plate 1433 to move along the trimming guide rail 1434. The second direction is the Z-axis direction as shown in the figure.

[0061] The cutting substrate 1431 provides a carrier for the cutting drive 1432 and the cutting mounting plate 1433, so that they are mounted vertically on the base 160.

[0062] The cutting guide rail 1434 can guide the movement of the cutting mounting plate 1433, making the movement of the cutting mounting plate 1433 more stable, improving the overall stability of the device operation, and improving the stability of the cutting edge of battery a.

[0063] In actual operation, the edge cutting drive 1432 drives the edge cutting mounting plate 1433 to move along the edge cutting guide rail 1434, close to the lower cutter 142, to perform the edge cutting operation. After the edge cutting is completed, the edge cutting drive 1432 drives the edge cutting mounting plate 1433 to move in the opposite direction along the edge cutting guide rail 1434, away from the lower cutter 142, to prepare for the next edge cutting operation.

[0064] refer to Figure 1 and Figure 3 In an optional embodiment of this application, the electro-precision edge trimming device further includes a lifting mechanism 170, which is used to drive the placement platform 110 to rise or fall so that the side of the battery a on the placement platform 110 moves onto the lower cutter 142.

[0065] By setting up the lifting mechanism 170, the placement platform 110 can be raised or lowered, thereby raising or lowering the battery a on the placement platform 110. Specifically, when the battery a to be edged is placed on the placement platform 110, the height of the side of the battery a is greater than the blade height of the lower cutter 142. After the battery a is positioned, by operating the lifting mechanism 170, the placement platform 110 will be lowered so that the side of the battery a just contacts the lower cutter 142, preparing for edge cutting. The edge cutting drive 1432 then drives the upper cutter 141 to lower, performing the edge cutting operation. Therefore, setting up the lifting mechanism 170 can move the side of the battery a more precisely to the position of the lower cutter 142, resulting in higher edge cutting accuracy and further ensuring the stability and consistency of edge cutting.

[0066] refer to Figure 3 In an optional embodiment of this application, the lifting mechanism 170 includes a lifting drive 171, a lifting base plate 172, and a lifting guide rail 173. The lifting guide rail 173 is arranged along a second direction. The lifting base plate 172 is connected to the placement platform 110. The driving end of the lifting drive 171 is connected to the lifting base plate 172. The lifting guide rail 173 is disposed on the lifting base plate 172. The lifting drive 171 drives the lifting base plate 172 to rise or fall, thereby driving the placement platform 110 to rise or fall, so that the side of the battery a on the placement platform 110 falls to the position of the lower cutter 142 for a more precise edge cutting operation. The lifting guide rail 173 guides the movement of the lifting base plate 172, making the movement of the lifting base plate 172 more stable, so that the battery a on the placement platform 110 moves smoothly.

[0067] In practice, the lifting drive component 171 can be a cylinder. The thrust of the cylinder can be adjusted by adjusting the air pressure through its own adjusting screw, which provides high flexibility in use.

[0068] refer to Figure 1 and Figure 3 In an optional embodiment of this application, the pushing mechanism 120 includes a pushing drive 121 and a pushing plate 122. The pushing drive 121 is fixed on the placement platform 110, and the driving end of the pushing drive 121 is connected to the pushing plate 122, thereby driving the pushing plate 122 to push the battery a so that its side abuts against the positioning baffle 111.

[0069] By setting the pusher drive component 121, the pusher plate 122 is provided with the power to push the battery a, and the battery a is pushed so that its side abuts against the positioning baffle 111, thereby achieving single-sided positioning of the battery a and positioning the battery a on the placement platform 110, ensuring the stability and consistency of subsequent edge cutting.

[0070] In practice, the pusher plate 122 can be made of imported epoxy board. Imported epoxy board usually has high strength, hardness and wear resistance, which can effectively absorb the pressure and vibration inside battery a caused by external force and maintain the stability of battery a.

[0071] Optionally, the pusher drive 121 can be a cylinder, and the thrust of the cylinder can be adjusted by adjusting the air pressure through its own adjusting screw, which provides high flexibility in use.

[0072] Combination Figures 1 to 3 The following describes the specific installation and operation process of the electro-precision trimming device according to an embodiment of this application:

[0073] The specific installation process of the electro-precision trimming device in this embodiment is as follows: Connect the placement platform 110 to the translation drive 151 and the lifting base plate 172; adjust the extension distance of the drive end of the translation drive 151 so that the trimming allowance of battery a meets the process requirements; install the push drive 121, the push plate 122, and the positioning baffle on the placement platform 110; adjust the balance between the push plate 122 and the positioning baffle 111 and the distance between them to adapt to the width of batteries a of different specifications; the positioning baffle 111 can be adjusted according to the thickness of the battery a to be trimmed as needed. Custom replacement; install the lower cutter 142 and the cutting plate 1431 on the base 160, and install the upper cutter 141 on the cutting plate mounting plate. Adjust the tightness of the contact between the upper cutter 141 and the lower cutter 142 so that no burrs are generated after cutting. Install the pressure drive 131 and the pressure plate 133. By adjusting the adjusting screw of the pressure drive 131 and controlling the output pressure of the pressure plate 133 on the battery a, this pressure can ensure that the single-sided positioning will not tilt. The push plate 122 can easily push the battery a to the positioning baffle 111 and abut against the positioning baffle 111.

[0074] The working process of the electro-precision trimming device in this embodiment is as follows: an external robotic arm places the battery a to be trimmed at a preset position on the placement platform 110; the translation drive 151 of the platform moving mechanism 150 drives the moving plate 153 to move along the translation guide rail 152, moving the placement platform 110 to the trimming station; the pressing drive 131 of the elastic pressing mechanism 130 drives the pressing plate 133 to move, so that the pressing plate 133 elastically contacts the upper surface of the battery a, and elastically presses the battery a against the placement platform 110. On the 0th floor; the pushing mechanism 120's pushing drive 121 drives the pushing plate 122 to push the battery a, so that the side of the battery a abuts against the positioning baffle 111 on the placement platform 110, realizing the single-sided positioning of the battery a; the lifting mechanism 170 drives the placement platform 110 to descend, so that the side of the battery a just contacts the lower cutter 142 of the cutting mechanism 140, and the cutting drive assembly 143 drives the upper cutter 141 to descend, cooperating with the lower cutter 142 to perform the cutting operation on the side of the battery a, completing the cutting operation of the battery a.
