Description

Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to a cover-closing device. Background Technology

[0002] Battery cap assembly is a crucial step in battery manufacturing, directly impacting the battery's sealing, safety, and performance. This process primarily involves accurately assembling and sealing the battery cap to the battery casing, ensuring the internal battery cells are in a stable environment. To reduce the number of steps, the battery cap is often fixed to the battery cells, allowing the cap to be closed simultaneously with the cell installation.

[0003] Current battery capping methods are mostly horizontal, with a device driving the battery cell with its cap or the cap to engage with the battery casing. For example, Chinese Patent CN117577921A discloses a cylindrical battery casing insertion device, which specifically discloses a pushing cylinder 141 driving a pushing fixture 142 to move and insert the battery cell into the casing. However, this method of capping is relatively simple, and because it is a horizontal pushing method, there is a possibility of downward displacement due to the weight of the battery cell, affecting the capping accuracy. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a cover-closing device to solve the technical problem that affects the installation accuracy of existing horizontal cell cover-closing installations.

[0005] To achieve the above-mentioned technical objectives, this application provides a lid-closing device, including a device carrier, a lid-closing mechanism, a supporting mechanism, and a displacement mechanism;

[0006] The supporting mechanism is installed on the device carrier and is provided with a supporting station for supporting the workpiece to be closed in the vertical direction;

[0007] The lid closing mechanism is mounted on the device carrier and is provided with a lid closing drive part that moves in the vertical direction;

[0008] The displacement mechanism is mounted on the device carrier and connected to the lid closing mechanism and / or the bearing mechanism, and is used to drive the lid closing mechanism and / or the bearing mechanism to move so that the lid closing drive unit is located directly above the bearing station.

[0009] Furthermore, the bearing station is provided with several limiting grooves;

[0010] The limiting groove is used to insert the workpiece to be covered and to limit and fix the inserted workpiece.

[0011] Furthermore, a vacuum adsorption component is provided in the limiting groove;

[0012] The vacuum adsorption component is provided with several adsorption holes for adsorbing and fixing the workpiece to be closed.

[0013] The vacuum adsorption component is connected to a vacuum pump.

[0014] Furthermore, each of the limiting grooves is surrounded by a plurality of limiting structures disposed on the bearing mechanism.

[0015] Furthermore, the limiting structure is a limiting block, which is evenly distributed around the circumference to form the limiting groove in the shape of a cylinder.

[0016] Furthermore, the limiting structure is a limiting plate, which is distributed in a U-shape to form a rectangular limiting groove.

[0017] Furthermore, the limiting structure used to form the limiting groove is connected to a driving component, enabling the limiting structure to move in order to clamp and limit the workpiece to be closed.

[0018] Furthermore, an avoidance groove is provided on the inner side of the limiting structure.

[0019] Furthermore, a lid-closing actuator is installed on the lid-closing mechanism;

[0020] The drive end of the driver is connected to a push rod, which is used to drive the push rod to move vertically;

[0021] The push rod forms the cover closing drive unit.

[0022] Furthermore, the displacement mechanism is a linear drive module;

[0023] The displacement mechanism is horizontally mounted on the device carrier;

[0024] The height of the bearing station is lower than that of the cover closing drive unit;

[0025] The displacement mechanism is connected to the bearing mechanism and is used to drive the bearing mechanism to move linearly;

[0026] The closing mechanism is located on one side of the supporting mechanism along the linear movement direction of the supporting mechanism.

[0027] As can be seen from the above technical solutions, the lid-closing device designed in this application uses the bearing station on the bearing mechanism to vertically support the workpiece to be closed. Then, the displacement mechanism makes the bearing station located below the lid-closing drive part on the lid-closing mechanism. Then, the vertical movement control of the lid-closing drive part realizes the lid-closing operation in the vertical direction. During this lid-closing process, the workpiece to be closed is stationary relative to the bearing mechanism and is fully supported by the bearing mechanism in the vertical direction. There will be no problem of downward displacement due to gravity, which effectively ensures the lid-closing accuracy. Attached Figure Description

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

[0036] This application discloses a lid-closing device.

[0037] Please see Figure 1 One embodiment of the lid-closing device provided in this application includes:

[0038] The device consists of a carrier 1, a cover closing mechanism 2, a bearing mechanism 3, and a displacement mechanism 4.

[0039] The device carrier 1 can be a support platform, and the specific structure is not limited.

[0040] The support mechanism 3 is installed on the device carrier 1 and is provided with a support station for supporting the workpiece to be covered in the vertical direction.

[0041] The lid closing mechanism 2 is mounted on the device carrier 1 and is provided with a lid closing drive unit that moves in the vertical direction.

[0042] The displacement mechanism 4 is installed on the device carrier 1 and connected to the lid closing mechanism 2 and / or the bearing mechanism 3, and is used to drive the lid closing mechanism 2 and / or the bearing mechanism 3 to move so that the lid closing drive unit is located directly above the bearing station.

[0043] In use, first install the workpiece to be covered on the bearing station, then control the displacement mechanism 4 to drive the cover closing mechanism 2 and / or the bearing mechanism 3 to move, so that the cover closing drive part is located directly above the bearing station, and then control the cover closing drive part to press down to complete the cover closing process.

[0044] The lid-closing device designed in this application uses a bearing station on the bearing mechanism 3 to vertically support the workpiece to be closed. Then, the displacement mechanism 4 positions the bearing station below the lid-closing drive unit on the lid-closing mechanism 2. The vertical movement control of the lid-closing drive unit enables the lid-closing operation in the vertical direction. During this lid-closing process, the workpiece to be closed is stationary relative to the bearing mechanism 3 and is fully supported by the bearing mechanism 3 in the vertical direction. There will be no downward displacement due to gravity, effectively ensuring the lid-closing accuracy.

[0045] The above is Embodiment 1 of a lid-closing device provided in this application. The following is Embodiment 2 of a lid-closing device provided in this application. Please refer to the following for details. Figures 1 to 3 .

[0046] Based on the solution of Embodiment 1 above:

[0047] Furthermore, the supporting station is equipped with several limiting grooves, which are used to insert the workpiece to be covered and to limit and fix the inserted workpiece. As a key support component in the entire cover-closing production process, the supporting station is carefully designed with several limiting grooves. These limiting grooves are meticulously designed and manufactured, and their shape, size, and layout fully consider the characteristics of the workpiece to be covered; when the workpiece is placed into the limiting groove, the limiting groove begins to perform its important limiting and fixing function.

[0048] Furthermore, such as Figure 2 As shown, in order to ensure a stable installation of the cover to be closed, a vacuum adsorption component 33 is provided in the limiting groove; the vacuum adsorption component 33 is provided with several adsorption holes 331 for adsorbing and fixing the workpiece to be closed, and the vacuum adsorption component 33 is connected to a vacuum pump (not shown in the figure).

[0049] The vacuum adsorption component 33 is a specially designed part that fits perfectly and tightly with the internal structure of the limiting groove. Its material is typically chosen for its good airtightness and mechanical strength, such as a composite material of high-strength rubber and a metal skeleton. This material can withstand certain pressure and friction while ensuring no leakage during long-term use, thus maintaining stable adsorption performance.

[0050] Furthermore, such as Figure 2 as well as Figure 3 As shown, for the design of the limiting groove, each limiting groove is surrounded by multiple limiting structures set on the bearing mechanism 3.

[0051] Regarding the number of limiting slots, there can be multiple slots, which can be divided into two groups:

[0052] One of the limiting structures is the limiting block 31, which is evenly distributed around the circumference to form a cylindrical limiting groove, thereby fixing the circular workpiece (cylindrical battery) to be covered.

[0053] Another set of limiting structures consists of limiting plates 32, which are distributed in a U-shape to form a rectangular limiting groove, thereby fixing the rectangular workpiece to be closed (rectangular battery).

[0054] The above design allows for the installation and fixing of different types of workpieces, improving the overall adaptability of the juicing process.

[0055] Furthermore, such as Figure 2 as well as Figure 3 As shown, the limiting structure used to form the limiting groove is connected to a driving component (not shown in the figure), which allows the limiting structure to move in order to clamp and limit the workpiece to be closed.

[0056] The limiting groove is designed as a variable clamping mechanism, which can fix workpieces of different sizes and further improve adaptability.

[0057] Taking the limiting block 31 as an example, the driving component can be a telescopic cylinder, etc., which is connected to the limiting block 31 through a connecting rod assembly (refer to the gripper structure), or directly connected to the limiting block 31, so as to drive the limiting block 31 to retract or open, thereby achieving the clamping and release of the workpiece to be closed.

[0058] Furthermore, such as Figure 3 As shown, an avoidance groove 311 is provided on the inner side of the limiting structure. The avoidance groove cooperates with the shell cover of the workpiece to be covered. When the shell cover of the workpiece to be covered is slightly larger than the opening position of the workpiece to be covered, the shell of the workpiece after being covered will protrude slightly. At this time, the avoidance groove 311 can be used to avoid the protruding part.

[0059] Furthermore, such as Figure 1 As shown, a lid-closing driver 21 is installed on the lid-closing mechanism 2. The driver is a telescopic cylinder, a lifting motor, etc. The driving end of the driver is connected to a push rod 22, which is used to drive the push rod 22 to move vertically. The push rod 22 forms the lid-closing driving part.

[0060] The specific number of cover-closing actuators 21 depends on the number of upper limit slots of the bearing mechanism 3, and there is no specific limit.

[0061] Furthermore, such as Figure 1 As shown, the displacement mechanism 4 is a linear drive module, such as a linear slide (cylinder slide, lead screw slide, etc.).

[0062] The displacement mechanism 4 is horizontally installed on the device carrier 1. The height of the bearing station is lower than that of the cover-closing drive unit. The displacement mechanism 4 is connected to the bearing mechanism 3 and is used to drive the bearing mechanism 3 to move linearly. The cover-closing mechanism 2 is set on one side of the bearing mechanism 3 along the linear movement direction of the bearing mechanism 3.

[0063] Regarding the installation of the cover closing mechanism 2, it is fixedly installed by two support plates 23 perpendicular to the device carrier 1, while the bearing mechanism 3 is fixedly installed by a corresponding bracket. Those skilled in the art can make changes to the design according to actual needs without restriction.

[0064] The foregoing has provided a detailed description of a lid-closing device provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
