Description

Technical Field

[0001] This utility model relates to the field of soft-pack battery production technology, and in particular to a heat sealing device with a micrometer leveling mechanism. Background Technology

[0002] Soft-pack batteries (also known as polymer lithium batteries), as a new type of lithium-ion battery, occupy an important position in the energy storage field due to their small size, light weight, high specific energy density, excellent safety performance, and flexible structural design. This type of battery can be customized in terms of shape and capacity according to the needs of end products, and is currently widely used in various fields such as power banks, large-capacity energy storage devices, medical electronic devices, Bluetooth motors, and portable audio systems.

[0003] The soft-pack battery uses an aluminum-plastic composite film as the encapsulation shell. After injecting a gel electrolyte, a hot-pressing edge sealing process is carried out to complete the overall encapsulation. Traditional heat sealing heads cannot adjust the angle, and after long-term use, it is difficult to ensure their levelness, which has an adverse effect on the heat sealing effect. Therefore, it is necessary to develop a heat sealing device with a micrometer leveling mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a heat sealing device with a micrometer leveling mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heat sealing device with a micrometer leveling mechanism includes a fixed block, an X-axis swing module, a Y-axis swing module, an X-axis angle adjustment module, a Y-axis angle adjustment module, and a heat sealing module. The fixed block has a first connecting boss at its lower end. The X-axis swing module includes a first swing block and a first locking assembly. The first swing block is rotatably mounted on the first connecting boss around the X-axis. The first locking assembly is used to fix the first swing block and the first connecting boss. The lower end of the first swing block has a second connecting boss. The Y-axis swing module includes a second swing block and a second locking assembly. The second swing block is rotatably mounted on the second connecting boss around the Y-axis. The second locking assembly is used to fix the second swing block and the second connecting boss. The heat sealing module is fixed below the second swing block.

[0007] The X-axis angle adjustment module includes an upper connecting block, a lower connecting block, a reset rod, a baffle, a reset spring, a micrometer, and a contact platform. The upper connecting block and the lower connecting block are fixed on the fixed block and the first swing block, respectively. The lower end of the reset rod is fixed on the lower connecting block and the upper end passes through the upper connecting block. The baffle is fixed on the upper end of the reset rod. The reset spring is sleeved on the reset rod. The upper and lower ends of the reset spring abut against the baffle and the upper connecting block, respectively. The contact platform is fixed above the lower connecting block. The micrometer is fixed on the upper connecting block and the telescopic end corresponds to the upper part of the contact platform.

[0008] The X-axis angle adjustment module corresponds to one side of the swing direction of the first swing block, and the Y-axis angle adjustment module has the same structure as the X-axis angle adjustment module and corresponds to one side of the swing direction of the second swing block.

[0009] Further description of the present invention: The first locking assembly includes a pressure plate, a spring washer and a locking screw. The first swing block is provided with a through hole. The upper end of the pressure plate is fixed on the fixed block. The first swing block corresponds to the space between the pressure plate and the first connecting boss. The locking screw passes through the spring washer, the pressure plate and the through hole in sequence and is threadedly connected to the first connecting boss. There is a gap between the outer periphery of the locking screw and the through hole.

[0010] Further description of the present invention: The second locking component is mounted on the first swing block and the second swing block, and the structure of the second locking component is the same as that of the first locking component.

[0011] Further description of the present invention: It also includes a limiting screw, which is threadedly connected to the fixing block and its lower end abuts against the top surface of the first swing block.

[0012] The beneficial effects of this invention are as follows: The fixing block is used to fix the lifting drive device at the heat sealing station. The lifting drive device drives the fixing block, thereby driving the heat sealing module to rise and fall, thus heat sealing the soft-pack battery. Before the heat sealing process begins, the angles of the first and second swing blocks are finely adjusted by the X-axis angle adjustment module and the Y-axis angle adjustment module, so that the heat pressure head on the heat sealing module is in a horizontal state, thereby improving the heat sealing effect. The specific operation is as follows: First, unlock the first locking component, allowing the first swing block to swing relative to the first connecting boss. Under the action of the return spring, the first swing block will swing and move the lower connecting block to the side of the upper connecting block until it contacts the platform and the telescopic end of the micrometer head. Alternatively, the telescopic end of the micrometer head can be adjusted to be close to the platform before unlocking the first locking component, thereby reducing the swing amplitude of the first swing block. Then, by adjusting the telescopic end of the micrometer head, the first swing block is adjusted to the required angle. The reading on the micrometer head can be used as an adjustment reference for more precise angle adjustment. After adjustment, lock the first locking component to fix the first swing block on the first connecting boss, thus completing the placement angle of the heat sealing module around the X-axis. Using the same principle, the placement angle of the heat sealing module around the Y-axis is adjusted by the Y-axis swing module and the Y-axis angle adjustment module, thereby adjusting the lower end face of the heat sealing head on the heat sealing module to a horizontal position. The advantage of this design is that it can precisely control the angle adjustment of the heat sealing head through the micrometer head, thereby quickly adjusting the heat sealing head to a horizontal position and improving the heat sealing effect.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1 to 4 As shown, a heat sealing device with a micrometer leveling mechanism includes a fixed block 1, an X-axis swing module 2, a Y-axis swing module 3, an X-axis angle adjustment module 4, a Y-axis angle adjustment module 5, and a heat sealing module 6. The fixed block 1 has a first connecting boss 11 at its lower end. The X-axis swing module 2 includes a first swing block 21 and a first locking component 22. The first swing block 21 is rotatably mounted on the first connecting boss 11 around the X-axis. The first locking component 22 is used to fix the first swing block 21 and the first connecting boss 11. The lower end of the first swing block 21 has a second connecting boss 211. The Y-axis swing module 3 includes a second swing block 31 and a second locking component 32. The second swing block 31 is rotatably mounted on the second connecting boss 211 around the Y-axis. The second locking component 32 is used to fix the second swing block 31 and the second connecting boss 211. The heat sealing module 6 is fixed below the second swing block 31.

[0022] The X-axis angle adjustment module 4 includes an upper connecting block 41, a lower connecting block 42, a reset rod 43, a baffle 44, a reset spring 45, a micrometer 46, and an abutment platform 47. The upper connecting block 41 and the lower connecting block 42 are respectively fixed on the fixed block 1 and the first swing block 21. The lower end of the reset rod 43 is fixed on the lower connecting block 42 and the upper end passes through the upper connecting block 41. The baffle 44 is fixed on the upper end of the reset rod 43. The reset spring 45 is sleeved on the reset rod 43. The upper and lower ends of the reset spring 45 abut against the baffle 44 and the upper connecting block 41, respectively. The abutment platform 47 is fixed above the lower connecting block 42. The micrometer 46 is fixed on the upper connecting block 41 and the telescopic end corresponds to the upper part of the abutment platform 47.

[0023] The X-axis angle adjustment module 4 corresponds to the swing direction side of the first swing block 21, and the Y-axis angle adjustment module 5 has the same structure as the X-axis angle adjustment module 4 and corresponds to the swing direction side of the second swing block 31.

[0024] The fixing block 1 is used to fix the lifting drive device at the heat sealing station. The lifting drive device drives the fixing block 1, thereby driving the heat sealing module 6 to rise and fall, thus heat sealing the soft-pack battery. Before the heat sealing process begins, the angles of the first swing block 21 and the second swing block 31 are finely adjusted by the X-axis angle adjustment module 4 and the Y-axis angle adjustment module 5, so that the hot pressure head on the heat sealing module 6 is in a horizontal state to improve the heat sealing effect. The specific operation is as follows: First, unlock the first locking component 22 so that the first swing block 21 can swing relative to the first connecting boss 11. Under the action of the return spring 45, the first swing block 21 will swing and move the lower connecting block 42 to the side of the upper connecting block 41 until it contacts the platform 47 and the telescopic end of the micrometer head 46. Alternatively, before unlocking the first locking component 22, the telescopic end of the micrometer head 46 can be adjusted to be close to the platform 47 to reduce the swing amplitude of the first swing block 21. Then, by adjusting the telescopic end of the micrometer head 46, the first swing block 21 can be adjusted to the required angle. The reading on the micrometer head 46 can be used as an adjustment reference to adjust the angle more accurately. After the adjustment is completed, lock the first locking component 22 to fix the first swing block 21 on the first connecting boss 11, thereby completing the placement angle of the heat sealing module 6 around the X-axis. Using the same principle, the Y-axis swing module 3 and the Y-axis angle adjustment module 5 are used to adjust the placement angle of the heat sealing module 6 around the Y-axis, thereby adjusting the lower end face of the heat sealing head on the heat sealing module 6 to a horizontal position. The advantage of this design is that it can precisely control the angle adjustment of the heat sealing head through the micrometer 46, thereby quickly adjusting the heat sealing head to a horizontal position and improving the heat sealing effect.

[0025] The first locking assembly 22 includes a pressure plate 221, a spring washer 222, and a locking screw 223. The first swing block 21 is provided with a through hole 212. The upper end of the pressure plate 221 is fixed on the fixed block 1. The first swing block 21 corresponds to the space between the pressure plate 221 and the first connecting boss 11. The locking screw 223 passes through the spring washer 222, the pressure plate 221, and the through hole 212 in sequence and is threadedly connected to the first connecting boss 11. There is a gap between the outer periphery of the locking screw 223 and the through hole 212.

[0026] In the locked state, the head of the locking screw 223 presses the spring washer 222 and the pressure plate 221 toward the first swing block 21, thereby fixing the first swing block 21 to the first connecting boss 11. When unlocking, the locking screw 223 is rotated to move it outward, and the spring washer 222 gradually returns to its original state, thereby reducing the pressure on the pressure plate 221. Similarly, the pressure of the pressure plate 221 on the first swing block 21 is also reduced, so that the first swing block 21 can swing relative to the first connecting boss 11.

[0027] The second locking component 32 is mounted on the first swing block 21 and the second swing block 31, and the structure of the second locking component 32 is the same as that of the first locking component 22. Similar to the first locking component 22, the second locking component 32 is used to fix the second swing block 31 and the second connecting boss 211, or to unlock both.

[0028] This design also includes a limiting screw 7, which is threadedly connected to the fixing block 1 and its lower end abuts against the top surface of the first swing block 21.

[0029] During the heat sealing process, the limiting screw 7 plays a role in limiting and supporting the first swing block 21, further fixing the first swing block 21 to the first connecting boss 11.

[0030] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
