Description

Technical Field

[0001] This application relates to the field of battery delivery technology, and in particular to a battery positioning device. 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, cylindrical fixtures are used to fix the batteries in place. The fixtures are equipped with strong magnetic blocks, and the ends of the batteries are firmly attached to the ends of the fixtures by the strong magnetic blocks. An insulating ring is provided on the end of the battery facing away from the fixtures. The fixtures are sequentially set on a chain conveyor to transport the batteries.

[0004] In related technologies, batteries on the tooling are directly transported from the coating process to the oven process. During the transport process, the batteries are prone to misalignment with the tooling. Misaligned batteries may cause some areas of the batteries to be too close to the heat source or insufficiently heated when they enter the oven, affecting the quality of the coating process and resulting in low battery production efficiency. Summary of the Invention

[0005] To address the problem of battery misalignment between the battery and tooling during direct transport from the coating process to the oven drying process, which affects the coating quality of subsequent processes and leads to low battery production efficiency, this application provides a battery positioning device with the following technical solution: It includes a mounting frame and a fixing frame mounted on a conveyor. A pusher is slidably connected to the fixing frame. The mounting frame is equipped with a battery limiting unit for limiting the battery and a tooling limiting unit for limiting the tooling. The battery limiting unit and the tooling limiting unit are located on the same side of the battery. The fixing frame is equipped with a first driving unit for driving the pusher to slide. The battery is pressed against the pusher and the battery limiting unit, and the tooling is pressed against the pusher and the tooling limiting unit.

[0006] In one specific implementation, the first drive unit includes a first drive cylinder mounted on a fixed frame, and a pusher is mounted at the output end of the first drive cylinder. The moving direction of the pusher is perpendicular to the conveying direction of the conveyor.

[0007] In one specific implementation, a limiting frame is slidably connected to the mounting bracket, a support frame is provided on the limiting frame, the battery limiting unit and the tooling limiting unit are disposed on the support frame, and a second driving unit for driving the limiting frame to slide is provided on the mounting bracket.

[0008] In one specific implementation, the battery limiting unit includes a battery limiting groove formed on the support frame that matches the battery, and the tooling limiting unit includes a tooling limiting groove formed on the support frame that matches the tooling. The battery limiting groove and the tooling limiting groove are located on the same side of the battery. The battery abuts against the groove wall of the battery limiting groove between the push frame and the tooling abuts against the groove wall of the tooling limiting groove between the push frame.

[0009] In one specific implementation, the support frame is provided with a first contour block that matches the battery, and the push frame is provided with a second contour block that matches the battery, with the battery pressed against the first contour block and the second contour block.

[0010] In one specific implementation, the support frame is slidably connected to the limiting frame, and the support frame is respectively provided with a first elastic element and a second elastic element. The support frame is located between the first elastic element and the second elastic element, and the first elastic element and the second elastic element are respectively pressed against the support frame and the limiting frame.

[0011] In one specific implementation, the limiting frame is provided with a limiting guide rail, and a limiting guide block that matches the limiting guide rail is slidably connected on the limiting guide rail, and the support frame is disposed on the limiting guide block.

[0012] In one specific implementation, the second drive unit includes a second drive cylinder mounted on a mounting bracket, and a limiting bracket is located at the output end of the second drive cylinder, wherein the moving direction of the limiting bracket is perpendicular to the conveying direction of the conveyor.

[0013] In one specific implementation, the support frame is provided with a pressing unit for flattening the insulating ring on the battery. The pressing unit includes a lifting cylinder disposed on the support frame, and the output end of the lifting cylinder is provided with a pressing head. The battery is located between the pressing head and the conveyor.

[0014] In one specific implementation, the limiting frame is provided with a first guide rail, and a first slider that matches the first guide rail is slidably connected on the first guide rail, and the support frame is disposed on the first slider.

[0015] In summary, this application has the following beneficial technical effects: before the battery enters the baking process, the first drive unit is activated, which drives the pusher of the first drive unit to extend, pressing the battery between the pusher and the battery limiting unit, and pressing the tooling between the pusher and the tooling limiting unit, thereby limiting the position of the battery and the tooling, reducing the possibility of relative positional deviation between the battery and the tooling, improving the positional accuracy between the battery and the tooling during the transportation process and before entering the baking process, reducing the defect rate of the baking process, and improving the production efficiency of the battery.

[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0020] This application discloses a battery positioning device.

[0021] Reference Figure 1 and Figure 2 The battery positioning device includes a mounting frame 2 and a fixed frame 3 mounted on a conveyor 1. In this embodiment, the tooling 20 is conveyed by the chain conveyor 1 and is located between the mounting frame 2 and the fixed frame 3. A pusher 4 is slidably connected to the fixed frame 3. The mounting frame 2 is provided with a battery limiting unit for limiting the battery 21 and a tooling limiting unit for limiting the tooling 20. The battery limiting unit and the tooling limiting unit are located on the same side of the battery 21. A first drive unit is provided on the fixed frame 3 for driving the pusher 4 to slide. The battery 21 is pressed against the pusher 4 and the battery limiting unit, and the tooling 20 is pressed against the pusher 4 and the tooling limiting unit. The first drive unit includes a first drive cylinder 5 mounted on the fixed frame 3. The pusher 4 is located at the output end of the first drive cylinder 5, and the moving direction of the pusher 4 is perpendicular to the conveying direction of the conveyor 1.

[0022] Therefore, before the battery 21 enters the drying process, the first drive cylinder 5 is activated, which drives the pusher 4 at the output end of the first drive cylinder 5 to extend, pressing the battery 21 against the pusher 4 and the battery limiting unit, and pressing the tooling 20 against the pusher 4 and the tooling limiting unit, thereby limiting the position of the battery 21 and the tooling 20, reducing the possibility of relative positional deviation between the battery 21 and the tooling 20, improving the positional accuracy between the battery 21 and the tooling 20 during the conveying process and before entering the drying process, reducing the defect rate of the drying process, and improving the production efficiency of the battery 21.

[0023] Reference Figure 1 and Figure 2 A limiting frame 6 is slidably connected to the mounting frame 2. A support frame 7 is mounted on the limiting frame 6. A battery limiting unit and a tooling limiting unit are mounted on the support frame 7. A second drive unit for driving the limiting frame 6 to slide is mounted on the mounting frame 2. The second drive unit includes a second drive cylinder 16 mounted on the mounting frame 2. The limiting frame 6 is located at the output end of the second drive cylinder 16, and the direction of movement of the limiting frame 6 is perpendicular to the conveying direction of the conveyor 1. Therefore, activating the second telescopic cylinder drives the limiting frame 6 at its output end to slide, enabling the limiting frame 6 and the support frame 7 to move, thus increasing flexibility.

[0024] Reference Figure 1 and Figure 2 The battery limiting unit includes a battery limiting groove 8 formed on the support frame 7 and matching the size of the battery 21. The tooling limiting unit includes a tooling limiting groove 9 formed on the support frame 7 and matching the size of the tooling 20. The battery limiting groove 8 and the tooling limiting groove 9 are located on the same side of the battery 21. The battery 21 is pressed against the groove wall of the battery limiting groove 8 and the push frame 4. The tooling 20 is pressed against the groove wall of the tooling limiting groove 9 and the push frame 4. In this embodiment, the tooling limiting groove 9 can be an arc groove and the battery limiting groove 8 can be a V-shaped groove.

[0025] Therefore, when the battery 21 on the chain conveyor 1 moves between the push plate and the tooling limiting groove 9, the chain conveyor 1 stops, the first drive cylinder 5 is started, and the push frame 4 at the output end of the first drive cylinder 5 is extended. At the same time, the second telescopic cylinder is started, and the limiting frame 6 and the support frame 7 at the output end of the second telescopic cylinder are extended, pressing the battery 21 against the push frame 4 and the battery limiting groove 8, and pressing the tooling 20 against the push frame 4 and the tooling limiting groove 9, thereby limiting the position of the battery 21 and the tooling 20. At this time, the axis of the battery 21 coincides with the axis of the tooling 20, and the battery 21 and the tooling 20 are coaxially arranged.

[0026] Reference Figure 1 and Figure 2 A first contour block 10 matching the size of the battery 21 is bolted to the support frame 7, and a second contour block 11 matching the size of the battery 21 is bolted to the push frame 4. The battery 21 is pressed between the first contour block 10 and the second contour block 11. The position of the battery 21 is further limited by the first contour block 10 and the second contour block 11, reducing the possibility of positional deviation of the battery 21 during transportation and improving the accuracy of the relative position between the battery 21 and the tooling 20 during transportation.

[0027] Reference Figure 1 and Figure 2The support frame 7 is slidably connected to the limiting frame 6. A first elastic element 12 and a second elastic element are respectively installed on the support frame 7. The first elastic element 12 and the second elastic element are arranged along the conveying direction of the chain conveyor 1. In this embodiment, both the first elastic element 12 and the second elastic element are compression springs. The support frame 7 is located between the first elastic element 12 and the second elastic element, and the first elastic element 12 and the second elastic element are respectively pressed against the support frame 7 and the limiting frame 6. Since there may be slight deviations in the position between each tooling 20 and the tooling limiting groove 9, and between the battery 21 and the battery limiting groove 8, the support frame 7 is designed to be floating by the first elastic element 12 and the second elastic element to easily handle slight misalignments between the tooling 20 and the tooling limiting groove 9, and between the battery 21 and the battery limiting groove 8. If there is a slight deviation between the battery 21 and the battery limiting groove 8, the elastic deformation of the compression spring will allow the support frame 7 to float slightly. The battery 21 will gradually contact the bottom of the battery limiting groove 8 along the groove wall, so that the support frame 7 can adaptively adjust according to the position of the battery 21, ensuring that the battery 21 can be accurately pressed between the battery limiting groove 8 and the push frame 4, and the tooling 20 can be accurately pressed between the tooling limiting groove 9 and the push frame 4. If the battery 21 model changes slightly, the elastic deformation of the spring can also provide a buffer, reducing the need for model change adjustment and improving the applicability of the battery positioning device.

[0028] Reference Figure 1 and Figure 2 A limiting frame 6 is bolted to a limiting guide rail 14, and a limiting guide block 15, matching the size of the limiting guide rail 14, is slidably connected to the limiting guide rail 14. A support frame 7 is mounted on the limiting guide block 15. A first guide rail 19 is bolted to the limiting frame 6, and a first slider 18, matching the size of the first guide rail 19, is slidably connected to the first guide rail 19. The support frame 7 is mounted on the first slider 18. In this embodiment, the limiting guide rail 14 and the first guide rail 19 are parallel to the conveying direction of the conveyor 1. A second guide rail is bolted to the mounting frame 2, and a second slider 22, matching the size of the second guide rail, is slidably connected to the second guide rail. The limiting frame 6 is bolted to the second slider 22. The second guide rail is perpendicular to the conveying direction of the chain conveyor 1. The second guide rail limits the movement direction of the limiting frame 6, improving the stability of the position of the limiting frame 6 when sliding along the mounting frame 2. The limiting guide rail 14 limits the movement direction of the limiting guide block 15, and the first guide rail 19 limits the movement direction of the first slider 18, thereby improving the stability of the position of the support frame 7 when it slides horizontally along the limiting frame 6.

[0029] Reference Figure 1 and Figure 2The support frame 7 is equipped with a pressing unit for flattening the insulating ring on the battery 21. Before the film coating process, the insulating ring is glued to the top of the battery 21. Since the film drying process requires the battery 21 to be plastic-sealed, the pressing unit needs to flatten the insulating ring before the battery 21 enters the film drying machine. This reduces the possibility of the insulating ring curling up during film drying and improves the quality of the battery 21. The pressing unit includes a lifting cylinder 17 vertically mounted on the support frame 7. A pressing head 13 is installed at the output end of the lifting cylinder 17. The battery 21 is located between the pressing head 13 and the conveyor 1. In this embodiment, the pressing head 13 can be made of rubber material to reduce the possibility of damaging the insulating ring during the flattening process. Therefore, when the lifting cylinder 17 is activated, the pressing head 13 at the output end of the lifting cylinder 17 descends, pressing the insulating ring between the battery 21 and the pressing head 13, thereby achieving automatic flattening of the insulating ring.

[0030] The implementation principle of this application embodiment is as follows: Before the battery 21 enters the drying process, when the battery 21 on the chain conveyor 1 moves between the push plate and the tooling limiting groove 9, the chain conveyor 1 stops, the first drive cylinder 5 is started, and the push frame 4 at the output end of the first drive cylinder 5 extends. At the same time, the second telescopic cylinder is started, and the limiting frame 6 and support frame 7 at the output end of the second telescopic cylinder extend, pressing the battery 21 against the push frame 4 and the battery limiting groove 8, and pressing the tooling 20 against the push frame 4 and the tooling limiting groove 9. The limiting groove 9 is installed between the battery 21 and the tooling 20 to limit their positions. At this time, the axis of the battery 21 coincides with the axis of the tooling 20, and the battery 21 and the tooling 20 are coaxially arranged. Then, the lifting cylinder 17 is activated, which drives the pressure head 13 at the output end of the lifting cylinder 17 to descend, pressing the insulating ring between the battery 21 and the pressure head 13, realizing automatic flattening of the insulating ring. After the insulating ring is flattened, the chain conveyor 1 is activated to transport the tooling 20 to the drying end of the drying machine for the drying process. Through the battery limiting unit and the tooling limiting unit, the possibility of relative positional deviation between the battery 21 and the tooling 20 is reduced, the positional accuracy between the battery 21 and the tooling 20 during the conveying process and before entering the drying process is improved, the defect rate of the drying process is reduced, and the production efficiency of the battery 21 is improved.
