Description

Technical Field

[0001] This invention relates to the field of steel-cased sealed welding battery processing and manufacturing, specifically to a single-sided hot-stamping device for steel-cased sealed welding battery cores. Background Technology

[0002] With the increasing application of cylindrical batteries, the market demands higher precision in their manufacturing process. The manufacturing process involves placing the cut positive and negative electrode sheets and separator on a winding machine. The winding machine then winds the positive and negative electrode sheets and separator into a series, securing them with tape to form the core. After installing an insulator at the bottom of the core, it is inserted into the battery casing, followed by the installation of an insulator at the top. Finally, electrolyte is injected, the top cover assembly is welded, and the casing is sealed. During the winding process, uneven edges on the core can occur, affecting the subsequent welding of the top cover. Currently, there is a lack of a device that can quickly and effectively heat-seal and shape the edges of the core. Summary of the Invention

[0003] The purpose of this invention is to provide a steel-shell sealed welding battery core single-sided hot edge heating device with ingenious structure, strong versatility and high precision.

[0004] A single-sided hot-stamping device for a steel-shell sealed welded battery core includes a base, a pressing mechanism, a hot-stamping assembly, and a reciprocating positioning plate. The hot-stamping assembly is connected to the pressing mechanism, and the pressing mechanism drives the hot-stamping assembly to move up and down. The reciprocating positioning plate is movably mounted on the base and has a battery turnover plate. The battery turnover plate moves back and forth toward the pressing mechanism under the action of the reciprocating positioning plate.

[0005] In the above scheme, the battery turnover board is used to place cylindrical batteries. The battery turnover board is installed on the reciprocating positioning plate. The reciprocating positioning plate is pushed in the direction of the pressing mechanism. After being pushed to the position below the ironing component, the start switch is pressed to press the pressing component and drive the ironing component to descend. At the same time, the temperature controller controls the ironing head component to heat to a suitable temperature. When the ironing head component is pressed down to the limited position, the core is ironed. This device can be equipped with multiple battery turnover boards to realize rapid rotation operation and improve production efficiency.

[0006] Furthermore, the pressing mechanism includes a fixed base, a lifting drive component, and a connecting plate. The lifting drive component is mounted on the fixed base and connected to the hot edge assembly. The side of the hot edge assembly closest to the fixed base is connected to the connecting plate.

[0007] In the above scheme, slider guide rail assemblies are provided on both sides of the lifting drive component. The connecting plate moves freely up and down on the slider guide rail assemblies. The lifting drive component is installed between the two slider guide rail assemblies. The movement direction of the lifting drive component is consistent with the movement direction of the connecting plate. A pad is added at the installation position of the lifting drive component so that the lifting drive component is in front of the connecting plate. The hot edge assembly is connected to the lifting drive component so that the hot edge assembly moves up and down under the drive of the lifting drive component. One side of the hot edge assembly is connected to the connecting plate to ensure the stability of the hot edge assembly movement. This structure is ingeniously designed, and the friction of the slider guide rail assembly is small, which can ensure the production accuracy.

[0008] Furthermore, it also includes a limiting mechanism, a grating ruler, and a digital display. The limiting mechanism includes a baffle and a micrometer, the micrometer is mounted on the baffle, the grating ruler is connected to the connecting plate, and the digital display is mounted on a fixed base.

[0009] In the above scheme, a groove is opened on the base between the pressing mechanism and the reciprocating positioning plate. The baffle is embedded in the groove and its installation position is adjusted according to the heating head mechanism and the positioning plate. At the same time, the baffle plays a limiting role for the reciprocating positioning block. The micrometer is installed on the baffle to limit the pressing position of the heating head mechanism. When the position of the heating edge does not meet the requirements, the micrometer is adjusted to adjust the position of the heating head mechanism. The grating ruler measures the pressing displacement of the heating head mechanism and displays it on the digital display to ensure that the position of the heating edge mechanism can be adjusted more accurately.

[0010] Furthermore, the ironing assembly includes an ironing head fixing plate and a plurality of core ironing heads, which are mounted side by side on the ironing head fixing plate.

[0011] In the above scheme, the core heating head faces downwards and connects the heating head fixing plate to the connecting plate, and at the same time connects to the movable end of the lifting drive component. The lifting drive component pushes the heating edge assembly to move up and down. The core heating head is matched with the diameter of the cylindrical battery core. Different core heating heads can be replaced according to different models of cylindrical batteries for heating edge, making the heating edge device in this scheme highly versatile and saving production costs.

[0012] Furthermore, a protective plate is provided in front of the curling iron head, and the protective plate is installed on the side of the iron head fixing plate away from the connecting plate.

[0013] In the above solution, the temperature of the core heating head is relatively high. During production, employees need to manually push the positioning plate to the designated position. During the operation, they may come into contact with the core heating head. In order to prevent employees from being burned, a protective plate is installed in front of the core heating head, which also provides a certain degree of protection for the core heating head.

[0014] Furthermore, the base is provided with a horizontal sliding assembly, and the reciprocating positioning plate is connected to the horizontal sliding assembly.

[0015] In the above scheme, the reciprocating positioning plate moves horizontally on the horizontal sliding component to move the battery turnover board to the bottom of the hot edge component for hot edge heating of the core. The reciprocating positioning plate is equipped with a handle to facilitate manual movement of the reciprocating positioning plate. After the hot edge heating is completed, the reciprocating positioning plate is pulled away from the hot edge component to facilitate the picking and placing of the battery turnover board.

[0016] Furthermore, the battery turnover plate is provided with several battery positioning cavities arranged side by side.

[0017] In the above scheme, the battery turnover board is used to place cylindrical batteries. Different battery positioning cavities are processed on the battery turnover board according to the specifications and models of the cylindrical batteries. After the cylindrical batteries are placed, the reciprocating positioning board is pushed to the limited position. The hot-edge component presses down to hot-edge the cylindrical battery core. Setting multiple battery turnover boards can realize rapid rotation operations and improve production efficiency.

[0018] Furthermore, a temperature control box is embedded in the side of the base, and the temperature controller is installed inside the temperature control box.

[0019] In the above solution, the temperature of the core heating head needs to be controlled by a temperature controller. Each core heating head can be equipped with an individual temperature controller. When heating the edges, the heating of the core heating head can be controlled according to the number and arrangement of the cylindrical batteries. Each temperature controller is equipped with a temperature control box. When the core heating head is heated to the appropriate temperature, the core of the cylindrical battery is heated. The temperature controller can achieve precise control and monitoring of the temperature of the core heating head.

[0020] The present invention provides a device for hot-pressing the edge of a steel-shell sealed welded battery core on one side, which has at least the following beneficial effects.

[0021] First, the structure is ingenious. The battery turnover plate is moved by the reciprocating positioning plate, and the pressing mechanism pushes the hot edge component to move downward to the limited position. At the same time, the hot edge component is heated to a suitable temperature to hot edge the cylindrical batteries on the battery turnover plate, which is very convenient to operate.

[0022] Secondly, it is highly versatile. The hot-rolling head of the hot-rolling component and the battery turnover board can be processed according to the specifications of cylindrical batteries. During production, the battery turnover board and the hot-rolling head can be replaced to hot-roll any steel-cased battery, saving costs.

[0023] Third, it has high production efficiency, as it can be equipped with multiple battery turnover boards to achieve rapid rotation operations, thereby improving production efficiency. Attached Figure Description

[0027] The following will describe in further detail the single-sided hot-edge device for sealing and welding battery cores with steel shell according to the present invention, with reference to specific embodiments and accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, in a preferred embodiment, a single-sided hot-edge device for a steel-shell sealed welded battery core of the present invention includes a base 1, a pressing mechanism 20, a hot-edge assembly 30, and a reciprocating positioning plate 5. The hot-edge assembly 30 is connected to the pressing mechanism 20, and the pressing mechanism 20 drives the hot-edge assembly 30 to move up and down. The reciprocating positioning plate 5 is movably mounted on the base 1, and a battery turnover plate 60 is provided on the reciprocating positioning plate 5. The battery turnover plate 60 reciprocates towards the pressing mechanism 20 under the drive of the reciprocating positioning plate 5. The battery turnover plate 60 is used to place cylindrical batteries. The battery turnover plate 60 is installed on the reciprocating positioning plate 5, and the ironing edge assembly 30 is suspended on the pressing mechanism 20. The reciprocating positioning plate 5 is pushed towards the pressing mechanism 20. After being pushed to a position below the ironing edge assembly 30, the start switch is pressed, and the pressing assembly drives the ironing edge assembly 30 to descend. At the same time, the temperature controller controls the ironing head assembly to heat to a suitable temperature. When the ironing head assembly is pressed down to the limited position, the core is ironed. This device can be equipped with multiple battery turnover plates 60 to achieve rapid rotation operation and improve production efficiency.

[0029] like Figure 1As shown, in some embodiments, the pressing mechanism 20 includes a fixed base 21, a lifting drive component 22, and a connecting plate 23. The lifting drive component 22 is mounted on the fixed base 21 and connected to the hot-edge assembly 23. The side of the hot-edge assembly 30 closest to the fixed base 21 is connected to the connecting plate 23. Slider guide rail assemblies are provided on both sides of the lifting drive component 22. The connecting plate 23 moves freely up and down on the slider guide rail assemblies. The lifting drive component 22 is installed between the two slider guide rail assemblies. The movement direction of the lifting drive component 22 is consistent with the movement direction of the connecting plate 23. A pad is added at the installation position of the lifting drive component 22 so that the lifting drive component 22 is located in front of the connecting plate 23. The hot-edge assembly 30 is connected to the lifting drive component 22 so that the hot-edge assembly 30 moves up and down under the drive of the lifting drive component 22. One side of the hot-edge assembly 30 is connected to the connecting plate 23 to ensure stable movement of the hot-edge assembly 30. This structure is ingeniously designed, and the friction of the slider guide rail assembly is low, which can ensure production accuracy.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, a limiting mechanism 90, a grating ruler 7, and a digital display 8 are also included. The limiting mechanism 90 includes a baffle 92 and a micrometer 91. The micrometer 91 is mounted on the baffle 92. The grating ruler 7 is connected to the connecting plate 23. The digital display 8 is mounted on the fixed base 21. A groove is opened on the base 1 between the pressing mechanism 20 and the reciprocating positioning plate 5. The baffle 92 is embedded in the groove and its installation position is adjusted according to the heating head mechanism and the positioning plate. At the same time, the baffle 92 plays a limiting role for the reciprocating positioning block, preventing the reciprocating positioning block from shifting and affecting the heating edge when the heating head assembly heats the core. The micrometer 91 is mounted on the baffle 92 to limit the pressing position of the heating head mechanism. When the heating edge position does not meet the requirements, the micrometer 91 is adjusted to adjust the position of the heating head mechanism. The grating ruler 7 measures the pressing displacement of the heating head mechanism and displays it on the digital display 8. The displacement of the heating edge assembly 30 is quantified so that the adjustment of the heating edge mechanism position can be more precise, thereby ensuring the accuracy of the battery core after heating edge.

[0031] like Figure 1As shown, in some embodiments, the edge-heating assembly 30 includes an edge-heating head fixing plate 31 and several core-heating heads 32, which are mounted side-by-side on the edge-heating head fixing plate 31. During production, a temperature controller controls the core-heating heads 32 to heat to a certain temperature to heat and shape the battery core, so that the battery can be better processed in the next step. The core-heating heads 32 face downwards and connect the edge-heating head fixing plate 31 to the connecting plate 23, and at the same time connect to the movable end of the lifting drive component 22. The lifting drive component 22 pushes the edge-heating assembly 30 to move up and down. The core-heating heads 32 are matched with the diameter of the cylindrical battery core. Different core-heating heads 32 can be replaced according to different models of cylindrical batteries for edge heating, making the edge-heating device in this solution highly versatile and saving production costs. The core-heating heads 32 can be made of materials with good thermal conductivity and ductility, such as copper.

[0032] like Figure 1 As shown, in some embodiments, a protective plate 11 is provided in front of the core ironing head 32, and the protective plate 11 is installed on the side of the ironing head fixing plate 31 away from the connecting plate 23. The core ironing head 32 has a high temperature, and during production, employees need to manually push the positioning plate to a limited position. During the operation, they may touch the core ironing head 32. In order to prevent employees from being burned, a protective plate 11 is installed in front of the core ironing head 32, which also provides a certain degree of protection for the core ironing head 32 and improves the safety of the ironing device.

[0033] like Figure 1 As shown, in some embodiments, the base 1 is provided with a horizontal sliding assembly 4, and a reciprocating positioning plate 5 is connected to the horizontal sliding assembly 4. The reciprocating positioning plate 5 moves horizontally on the horizontal sliding assembly 4 to move the battery turnover plate 60 to the underside of the hot-pressing assembly 30 for hot-pressing the core. The reciprocating positioning plate 5 is equipped with a handle to facilitate manual movement. After hot-pressing is completed, the reciprocating positioning plate 5 is pulled away from the hot-pressing assembly 30 to facilitate the loading and unloading of the battery turnover plate 60. The movement of the battery turnover plate 60 through the reciprocating positioning plate 5 does not cause significant deviation, ensuring production accuracy.

[0034] like Figure 1 As shown, in some embodiments, the battery turnover plate 60 is provided with several parallel battery positioning cavities 61. The battery turnover plate 60 is used to place cylindrical batteries. Different battery positioning cavities 61 are processed on the battery turnover plate 60 according to the specifications and models of the cylindrical batteries. After the cylindrical batteries are placed, the reciprocating positioning plate 5 is pushed to a predetermined position, and the hot-edge assembly 30 presses down to hot-edge the cylindrical battery core. Setting multiple battery turnover plates 60 can realize rapid rotation operations and improve production efficiency.

[0035] like Figure 1As shown, in some embodiments, a temperature control box 10 is embedded in the side of the base 1, and a temperature controller is installed inside the temperature control box 10. The temperature of the core heating head 32 needs to be controlled by the temperature controller. Each core heating head 32 can be equipped with an individual temperature controller. When heating the edges, the heating of the core heating head 32 can be controlled according to the number and arrangement of the cylindrical batteries. Each temperature controller is equipped with a temperature control box 10. When the core heating head 32 is heated to a suitable temperature, the core of the cylindrical battery is heated. The temperature controller can achieve precise control and monitoring of the temperature of the core heating head 32.

[0036] This invention discloses the working principle and process of a single-sided hot-edge device for a steel-shell sealed welded battery core. After the battery steel shell and core are installed, they are placed into the battery positioning cavity 61 of the battery turnover plate 60. Then, the battery turnover plate 60 is fixed on the reciprocating positioning plate 5. The reciprocating positioning plate 5 is pushed until it contacts the baffle 92. At this time, the battery is directly below the core hot-edge head 32. The start button is pressed, and the lifting drive component 22 pushes the hot-edge head fixing plate 31 down. At the same time, the temperature controller controls the core hot-edge head 32 to heat up to a certain temperature. The core hot-edge head 32 contacts the battery core to complete the hot-edge process. Then, the lifting drive component 22 drives the hot-edge assembly 30 to rise, pulling the reciprocating positioning plate 5 towards the principle pressing mechanism 20. After removing the battery turnover plate 60, the hot-edge-completed battery is sent to the next process.
