A membrane lifting mechanism

Abstract

This application relates to a protective film lifting mechanism for battery coating. It includes a base, a chain conveyor mounted on the base, and several limiting devices on the chain conveyor for limiting the position of the tooling. The base also includes a lifting device for driving the limiting devices to lift, and the lifting device corresponds to the film supply end of the coating machine. The technical advantage of this application is that the lifting mechanism first lifts the tooling before coating, and after coating, the tooling is lowered. After the tooling is lowered, the chain conveyor is activated to transport the tooling again. This reduces the possibility of the protective film end on the battery end of the tooling bending due to lateral shear force when directly transported by the chain conveyor. The chain conveyor transports the tooling after the end of the protective film on the battery is disconnected from the end of the protective film on the coating machine, ensuring the protective film is flatly coated on the battery surface, thus improving the coating yield and production efficiency.

Description

Technical Field

[0001] This application relates to the field of battery sleeve technology, and in particular to a sleeve lifting mechanism. Background Technology

[0002] A battery is a device that directly converts chemical energy, light energy, or thermal energy into electrical energy, and achieves energy storage and release through oxidation-reduction reactions.

[0003] During battery production, tooling is used to secure the batteries. The tooling is equipped with strong magnetic blocks, which firmly attach the battery ends to the tooling ends. A mounting block is located at the end of the tooling away from the battery. Several tooling units are conveyed on a chain conveyor, each limited by the mounting blocks. When the tooling reaches the film supply end of the coating machine, the machine is activated to coat the battery with protective film, placing the film on the outer perimeter of the battery. The coated tooling is then directly conveyed by the chain conveyor to the next process.

[0004] During the battery coating process, the coated batteries are directly transported by the chain conveyor. Under the action of the chain conveyor, the end of the protective film coated on the battery is offset from the end of the protective film supplied by the coating machine. This causes the end of the protective film coated on the battery to be offset or bent by the lateral shear force, affecting the quality of the battery coating. Summary of the Invention

[0005] To address the problem in related technologies where, after the battery is coated, it is directly conveyed by a chain conveyor, causing misalignment between the end of the battery protective film and the protective film at the film supply end of the coating machine. This misalignment or bending of the protective film end, caused by shear force, affects the quality of the battery coating, this application provides a coating lifting mechanism with the following technical solution: It includes a base, a chain conveyor mounted on the base, and several limiting devices on the chain conveyor for limiting the position of the tooling. The base is equipped with a lifting device for driving the limiting devices to lift, and the lifting device corresponds to the film supply end of the coating machine.

[0006] In one specific implementation, the limiting device includes a lifting plate disposed on a chain conveyor, the lifting plate having a positioning hole, a positioning bolt matching the positioning hole passing through the chain conveyor, the end of the positioning bolt facing the lifting plate being threaded into the positioning hole, and the lifting plate having a limiting unit for limiting the position of the tooling.

[0007] In one specific implementation, the limiting unit includes a limiting bolt that passes through the lifting plate, and the mounting block of the tooling has a limiting groove at one end facing the lifting plate that matches the limiting bolt, and the limiting bolt is threaded into the limiting groove.

[0008] In one specific implementation, the lifting device includes a lifting cylinder mounted on a base, the output end of the lifting cylinder being provided with a lifting frame, the lifting frame being provided with a stop block, and the stop block being located between the lifting plate and the lifting frame.

[0009] In one specific implementation, the lifting frame has a groove on the surface facing the lifting plate that matches the abutment block, the abutment block is slidably connected in the groove, and the lifting frame is provided with a fixing unit for fixing the position of the abutment block in the groove.

[0010] In one specific implementation, the fixing unit includes a first oblong hole formed at the bottom of the slide groove, a fixing bolt passing through the first oblong hole, and a threaded groove matching the fixing bolt formed on the surface of the abutment facing the slide groove, with one end of the fixing bolt facing the abutment threadedly connected to the threaded groove.

[0011] In one specific implementation, the chain conveyor is provided with a connecting block, and the connecting block has a stop block on its surface facing the tooling, the stop block being located between the film supply end of the film-making machine and the lifting plate.

[0012] In one specific implementation, the side of the stop block facing the lifting plate has a chamfer.

[0013] In one specific implementation scheme, the connecting block has a second oblong hole, a first adjusting bolt passes through the second oblong hole, and the side of the stop block facing the connecting block has a first adjusting groove that matches the first adjusting bolt. The end of the first adjusting bolt facing the stop block is threaded into the first adjusting groove.

[0014] In one specific implementation scheme, the connecting block is provided with a third oblong hole, a second adjusting bolt is inserted into the third oblong hole, and a second adjusting groove matching the second adjusting bolt is provided on the surface of the chain conveyor facing the connecting block. The end of the second adjusting bolt facing the conveyor is threaded into the second adjusting groove.

[0015] In summary, this application has the following beneficial technical effects: When a battery needs to be coated, the tooling is limited by a limiting device and conveyed on a chain conveyor. When the tooling moves to the film supply end of the coating machine, the chain conveyor stops, and the lifting device is started to lift the limiting device and the battery on the tooling. Then, the coating machine is started to coat the battery. After the coating machine finishes coating, the lifting device drives the tooling to descend and reset. After resetting to the initial position, the chain conveyor starts to transport the coated tooling to the next process. By using a lifting mechanism to lift the tooling before coating the battery, and then lowering the tooling after coating, the chain conveyor is started to transport the tooling again. This reduces the possibility of the protective film at the battery end bending due to lateral shear force when the chain conveyor directly transports the battery. The chain conveyor transports the battery after the end of the protective film on the battery is disconnected from the end of the protective film on the coating machine, ensuring that the protective film is flatly coated on the battery surface, thus improving the coating yield and production efficiency.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a membrane lifting mechanism.

[0022] Reference Figure 1 , Figure 2 and Figure 3The film-coating lifting mechanism includes a base, a chain conveyor 1 mounted on the base, and a number of limiting devices on the chain conveyor 1. The limiting devices are used to limit the position of the tooling 15. A lifting device is provided on the base to drive the limiting devices to lift. The lifting device corresponds to the film supply end of the film-coating machine, that is, the lifting device and the film supply end of the film-coating machine are on the same straight line in the vertical direction. In this embodiment, the film-coating machine adopts the conventional film-coating machine used in the prior art for film-coating operations on batteries.

[0023] Therefore, when battery coating is required, fixture 15 is limited by a limiting device and conveyed on the chain conveyor 1. When fixture 15 moves to the film supply end of the coating machine, the chain conveyor 1 stops, the lifting device is activated, and the limiting device and fixture 15 are lifted. Then, the coating machine is started to coat the battery. After the coating is completed, the lifting device lowers fixture 15 to its initial position. After resetting to its initial position, the chain conveyor 1 starts to transport the coated battery to the next process. By using a lifting mechanism to first lift fixture 15 before coating the battery, and then lowering fixture 15 after the protective film is removed, the possibility of the protective film at the end of the battery bending due to lateral shear force when the chain conveyor 1 directly conveys the battery is reduced. This ensures that the protective film is smoothly coated on the battery surface, improving the coating yield and production efficiency.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The limiting device includes a lifting plate 2 installed on the chain conveyor 1. The lifting plate 2 has a positioning hole 4. A positioning bolt 3 matching the size of the positioning hole 4 is installed on the chain conveyor 1. The end of the positioning bolt 3 facing the lifting plate 2 is threaded into the positioning hole 4. The operator can remove the lifting plate 2 from the chain conveyor 1 by removing the bolt, so as to realize the detachable connection of the lifting plate 2 and make it more flexible.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The lifting plate 2 is equipped with a limiting unit for positioning the tooling 15. The limiting unit includes a limiting bolt 5 that passes through the lifting plate 2. One end of the tooling 15 has a mounting block, and the mounting block facing the lifting plate 2 has a limiting groove 6 that matches the size of the limiting bolt 5. The limiting bolt 5 is threaded into the limiting groove 6. Therefore, the operator can install the tooling 15 onto the lifting plate 2 using bolts, achieving a detachable connection between the tooling 15 and the lifting plate 2, providing greater flexibility.

[0026] Reference Figure 1 , Figure 2 and Figure 3The lifting device includes a lifting cylinder 7 mounted on a base. The output end of the lifting cylinder 7 is bolted to a lifting frame 16. In this embodiment, two lifting cylinders 7 are used, and the lifting frame 16 is located between the output ends of the two lifting cylinders 7. A stop block 8 is mounted on the lifting frame 16, located between the lifting plate 2 and the lifting frame 16. In this embodiment, two stop blocks 8 are used, and a tooling 15 is located between the two stop blocks 8. Therefore, activating the lifting cylinder 7 lifts the lifting frame 16 and the stop block 8 at the output end of the lifting cylinder 7, and the stop block 8 applies a force to the lifting plate 2, causing the lifting plate 2 to rise.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The lifting frame 16 has a groove 9 on its surface facing the lifting plate 2, which matches the size of the abutment block 8. The abutment block 8 is slidably connected in the groove 9, and the groove 9 limits the movement direction of the abutment block 8, improving the stability during the movement of the block. The lifting frame 16 is provided with a fixing unit for fixing the position of the abutment block 8 in the groove 9. The fixing unit includes a first oblong hole 10 opened at the bottom of the groove 9, in which a fixing bolt passes. The surface of the abutment block 8 facing the groove 9 has a threaded groove that matches the size of the fixing bolt. One end of the fixing bolt facing the abutment block 8 is threaded into the threaded groove. The operator can fix the abutment block 8 on the lifting frame 16 by bolt connection. At the same time, the position of the abutment block 8 on the lifting frame 16 can be adjusted by using the first oblong hole 10, improving the flexibility of the position of the abutment block 8.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The chain conveyor 1 is equipped with a connecting block 11. A stop block 12 is installed on the surface of the connecting block 11 facing the tooling 15. The stop block 12 is located between the film supply end of the film-making machine and the lifting plate 2. The surface of the stop block 12 facing the lifting plate 2 has a chamfer, which reduces the possibility of the sharp edge damaging the lifting plate 2. Therefore, the stop block 12 limits the lifting position of the lifting plate 2, reducing the possibility of the lifting plate 2 being raised too high in case of accidents.

[0029] Reference Figure 1 , Figure 2 and Figure 3The connecting block 11 has a vertically arranged second oblong hole 13, and a first adjusting bolt passes through the second oblong hole 13. The stop block 12 has a first adjusting groove on its surface facing the connecting block 11, which matches the size of the first adjusting bolt. The end of the first adjusting bolt facing the stop block 12 is threaded into the first adjusting groove. The operator can install the stop block 12 on the connecting block 11 by bolt connection, so as to realize the detachable connection of the stop block 12. The vertically arranged second oblong hole 13 can also be used to adjust the vertical height of the stop block 12 on the connecting block 11. In the embodiment of this application, the distance between the end face of the stop block 12 facing the chain conveyor 1 and the end face of the lifting plate 2 facing the stop block 12 can be 1 to 6 mm.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The connecting block 11 has a horizontally set third oblong hole 14, and a second adjusting bolt passes through the third oblong hole 14. The surface of the chain conveyor 1 facing the connecting block 11 has a second adjusting groove that matches the size of the second adjusting bolt. The end of the second adjusting bolt facing the conveyor is threaded into the second adjusting groove. The operator can install the connecting block 11 on the chain conveyor 1 by bolt connection, so as to realize the detachable connection of the connecting block 11. The horizontally set third oblong hole 14 can also be used to adjust the position of the connecting block 11 on the chain conveyor 1, which improves the flexibility of the position of the connecting block 11.

[0031] The implementation principle of this application embodiment is as follows: When it is necessary to perform a coating operation on the battery, the fixture 15 is mounted on the lifting plate 2 and transported by the chain conveyor 1. The battery is adsorbed on the fixture 15. When the fixture 15 moves to the film supply end of the coating machine, the chain conveyor 1 stops and the lifting cylinder 7 is started, which drives the lifting frame 16 and the stop block 8 at the output end of the lifting cylinder 7 to lift. The stop block 8 applies a force to the lifting plate 2 to make the lifting plate 2 rise. After the fixture 15 is raised, the coating machine is started to coat the battery on the fixture 15. After the coating machine finishes coating, the lifting cylinder 7 drives the lifting frame 16 and the stop block 8 to descend and reset to the initial position. The chain conveyor 1 is started to transport the coated battery to the next process.

[0032] The lifting mechanism first lifts the tooling 15 and then applies the protective film. After the tooling 15 is lowered, the chain conveyor 1 then transports the protective film. At this time, the protective film has been completely applied and there is no external force pulling it. This reduces the possibility that the end of the protective film at the battery end will be bent due to the lateral shear force when the chain conveyor 1 directly transports the battery. This makes the protective film flat on the battery surface, improving the yield rate of the protective film and production efficiency.
