Description

Technical Field

[0001] This invention relates to the field of automated conveying technology, and in particular to a turning device and a core conveying line adapted to a core conveying line. Background Technology

[0002] In the battery cell production process, from the core winding stage to the assembly stage, conveyor lines are typically used to transport the cores. Generally, the cores are placed on core trays and transported along main and branch lines. Figure 1 The diagram shows the relative positions of the core 1 and the core tray 2. The core tray 2 is provided with a core placement area 21 formed by several limiting members. The tabs 11 of the core 1 are placed in the corresponding core placement area 21.

[0003] However, currently, during the conveying process of the battery cores on the production line, powder shedding occurs. Investigations revealed that the different battery core conveyor lines experiencing this powder shedding all share the characteristic of having the core conveying direction parallel to the core tab orientation. Furthermore, the core near the tab is pulled out due to the removal of the winding needle. When the core conveying direction is parallel to the core tab orientation, the tab side of the core is prone to colliding with the core tray, resulting in powder shedding and affecting the cell quality. Additionally, right-angle turns are frequently formed at the intersection of two conveyor components in the conveyor line, such as... Figure 2 As shown, on the conveyor line from winding equipment A to assembly equipment C, there are right-angle turns at the intersection of winding unloading conveyor A1 and core main conveyor B, and at the intersection of core main conveyor B and assembly loading conveyor C1. Currently, the lifting and transfer method is often used at the right-angle turns of the conveyor line. However, this method results in the core tray having different directions on the two conveyors. There is always one direction where the conveying direction and the tab orientation cannot be parallel, which leads to the core always shedding powder. Summary of the Invention

[0004] Based on this, and in response to the problems existing in the prior art mentioned in the background section, the present invention provides a turning device and a core conveying line adapted to a core conveying line, which effectively avoids powder shedding during the core conveying process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] The present invention provides a turning device adapted to a core conveying line. The conveying line includes a first conveyor and a second conveyor for conveying a core tray carrying cores. The conveying directions of the first conveyor and the second conveyor are at a predetermined angle. The turning device is used to guide the core tray carrying cores on the first conveyor to the second conveyor, and the tabs of the cores on the core tray are always perpendicular to the moving direction of the core tray.

[0007] This invention sets the orientation of the core tabs on the first conveyor to be perpendicular to the conveying direction of the first conveyor, thus avoiding collisions between the core tabs and the core tray during conveying. At the same time, a turning device is provided to guide the core tray carrying the core on the first conveyor to the second conveyor. Throughout the process, the orientation of the core tabs on the core tray is always perpendicular to the moving direction of the core tray, thereby effectively preventing collisions between the core tabs and the core tray, avoiding core powder shedding, and effectively ensuring the quality of the battery cells.

[0008] As a further improvement to the above-described solution of the present invention, one end of the first conveyor is connected to the second conveyor; the turning device includes:

[0009] The guide component has an arc-shaped channel. The inlet and outlet ends of the arc-shaped channel connect to conveyor component one and conveyor component two, respectively. When the core tray moves to the connection position between conveyor component one and conveyor component two, the core tray enters the arc-shaped channel under the conveying action of conveyor component one; and

[0010] The transmission component is used to transport the core tray in the arc-shaped channel to the second transmission component. The transmission speed of the transmission component is greater than the transmission speed of the first and second transmission components.

[0011] As a further improvement to the above-mentioned solution of the present invention, the width of the arc-shaped channel is L1, and the width of the core tray in the direction perpendicular to its moving direction is L2, and L1 is not less than L2.

[0012] As a further improvement to the above-mentioned solution of the present invention, the conveyor line is T-shaped, with conveyor one distributed along the longitudinal direction of the T and conveyor two distributed along the transverse direction of the T; the arc-shaped channel coincides with conveyor two, the feed end of the arc-shaped channel extends to the conveying surface of conveyor one and the conveying direction of its feed end is consistent with the conveying direction of conveyor one, and the conveying direction of the discharge end of the arc-shaped channel is consistent with the conveying direction of conveyor two.

[0013] As a further improvement of the above-mentioned solution of the present invention, the guide includes a guide limiting block one and a guide limiting block two arranged opposite to each other, and the opposite side of the guide limiting block one and the guide limiting block two are both arc-shaped surfaces to form an arc-shaped channel between them.

[0014] As a further improvement of the above-mentioned solution of the present invention, one end of the guide limiting block 1 and the guide limiting block 2 are respectively disposed on both sides of the conveying surface of the conveying component 1, the other end of the guide limiting block 1 is disposed on one side of the conveying surface of the conveying component 2, and the other end of the guide limiting block 2 extends across the conveying component 2 to the other side of the conveying surface of the conveying component 2.

[0015] As a further improvement to the above-described solution of the present invention, the turning device further includes a lifting component for driving the guide limiting block two to move up and down in the vertical direction.

[0016] As a further improvement of the above-mentioned solution of the present invention, the lifting component includes a cylinder and two guide rods. One end of each guide rod is connected to both ends of the second guide limiting block, and the other end of each guide rod slides through a mounting frame. The mounting frame is installed on an external device, and the cylinder is installed on the external device with its telescopic end connected to the bottom middle part of the second guide limiting block.

[0017] As a further improvement of the above-mentioned solution of the present invention, the transmission component is a linear conveyor, the conveying surface of the transmission component is located within the conveying surface of the second conveyor and its conveying direction is consistent with the conveying direction of the second conveyor. One end of the transmission component extends from the discharge end of the arc-shaped channel into the arc-shaped channel. The core tray that enters the arc-shaped channel rotates onto the transmission component with the center of the inner arc surface of the arc-shaped channel as the fulcrum under the action of the transmission component and moves onto the second conveyor under the action of the transmission component.

[0018] The present invention also proposes a core conveyor line, which includes a turning device adapted to the core conveyor line as described above.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In this invention, the core tabs on the first conveyor are oriented perpendicularly to the conveying direction of the first conveyor to avoid collisions between the core tabs and the core tray during conveying. At the same time, a turning device is provided to guide the core tray carrying the core on the first conveyor to the second conveyor. Throughout the process, the core tabs on the core tray are always oriented perpendicularly to the moving direction of the core tray, thereby effectively preventing collisions between the core tabs and the core tray, avoiding core powder shedding, and effectively ensuring the quality of the battery cells.

[0021] 2. The turning device of the present invention is provided with a guide and a transmission component. The guide has an arc-shaped channel. The conveying speed of the transmission component is greater than the conveying speed of the first and second conveyors. This makes the moving speed of the core tray entering the arc-shaped channel near the inner arc surface of the arc-shaped channel lower than its moving speed near the outer arc surface of the arc-shaped channel. This allows the core tray to rotate around the center of the inner arc surface of the arc-shaped channel as a fulcrum to pass through the arc-shaped channel, thereby making a right-angle turn between the first and second conveyors.

[0022] 3. The turning time of the bending device of the present invention is shorter than that of the lifting and transplanting time, which is more efficient and does not damage the integrity of the main line. The application of the bending device of the present invention expands the conveying form, improves the conveying efficiency, and ensures the quality of the core. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example

[0031] This embodiment addresses the technical problem of core 1 shedding powder during the current production line conveying process by proposing a turning device. The turning device of this embodiment is suitable for core conveying lines that use core trays 2 to transport cores. On the conveying line from the core winding process to the assembly process, L-shaped or T-shaped right-angle turns are often formed at the intersection of two conveying components. The two conveying components forming the right-angle turn are defined as conveyor 3 and conveyor 4, respectively. Conveyor 3 transports the core tray 2 carrying the core 1 towards conveyor 4.

[0032] To prevent the core 1 from shedding powder, in this embodiment, the core tabs 11 on the first conveyor 3 are first set perpendicular to the conveying direction of the first conveyor 3 to avoid collision between the core tabs 11 and the core tray 2 during the conveying process; at the same time, the discharge end of the first conveyor 3 is directly connected to the second conveyor 4. In this embodiment, a turning device is set to guide the core tray 2 carrying the core 1 on the first conveyor 3 to the second conveyor 4. Throughout the process, the tabs 11 of the core 1 on the core tray 2 are always perpendicular to the moving direction of the core tray 2.

[0033] Please refer to Figure 3The turning device adapted to the core conveyor line in this embodiment includes a guide 5 and a transmission 6, and may also include a lifting 7.

[0034] The guide component 5 includes a guide limiting block 1 51 and a guide limiting block 2 52 arranged opposite to each other. One end of the guide limiting block 1 51 and the guide limiting block 2 52 are respectively located on both sides of the conveying surface of the conveying component 1 3, and the other end of the guide limiting block 1 51 is located on one side of the conveying surface of the conveying component 2 4. The other end of the guide limiting block 2 52 extends across the conveying component 2 4 to the other side of the conveying surface of the conveying component 2 4. The opposite sides of the guide limiting blocks 1 51 and 2 52 are both arc-shaped surfaces to form an arc-shaped channel between them. Thus, the arc-shaped channel coincides with the conveying component 2 4, the feeding end of the arc-shaped channel extends to the conveying surface of the conveying component 1 3 and its conveying direction is consistent with the conveying direction of the conveying component 1 3, and the conveying direction of the discharging end of the arc-shaped channel is consistent with the conveying direction of the conveying component 2 4. The core tray 2 conveyed by the conveying component 1 3 can be directly conveyed to the point where the arc-shaped channel coincides with the conveying component 2 4 under the conveying force of the conveying component 1 3. To ensure that the core tray 2 can smoothly enter the arc-shaped channel, the width of the arc-shaped channel is set to L1, and the width of the core tray 2 in the direction perpendicular to its moving direction is L2, and L1 is not less than L2.

[0035] The transmission component 6 is used to transport the core tray 2 in the arc-shaped channel to the second conveyor component 4. The conveying speed of the transmission component 6 is greater than that of the first conveyor component 3 and the second conveyor component 4. Thus, under the action of the transmission component 6, the moving speed of the core tray 2 near the first guide limit block 51 is lower than that near the second guide limit block 52. This allows the core tray 2 to rotate around the center of the arc surface of the first guide limit block 51 and rotate onto the transmission component 6 under the guidance of the arc surface of the second guide limit block 52. Under the action of the transmission component 6, it moves onto the second conveyor component 4. Throughout the process, the tabs 11 of the core on the core tray 2 are always perpendicular to the moving direction of the core tray 2. In this embodiment, the transmission component 6 is a linear conveyor and its conveying direction is consistent with that of the second conveyor component 4. The transmission component 6 is located within the conveying surface of the second conveyor component 4, and the conveying surface of the transmission component 6 and the conveying surface of the second conveyor component 4 are on the same horizontal plane. The feed end of the transmission component 6 extends from the discharge end of the arc-shaped channel into the arc-shaped channel. Of course, in other embodiments, the transmission component 6 can also be an arc-shaped conveyor, as long as it can ensure that the core tray 2 has a rotational tendency. Meanwhile, the thickness of the first guide limit block 51 and the second guide limit block 52 is not less than the height of the core tray 2 carrying the core 1, ensuring that the core tray 2 can smoothly pass through the arc-shaped channel. In this embodiment, the transmission component 6 can adopt existing technology, such as a belt conveyor mechanism.

[0036] Because there are L-shaped and T-shaped right-angle turns on the conveyor line, for the T-shaped right-angle turns, combined with... Figure 4This embodiment also includes a lifting component 7 that drives the guide limit block to rise and fall vertically. Since the guide limit block 52 spans the conveyor 4, the core tray 2 upstream of the conveyor 4 is blocked by the guide limit block 52 at the T-shaped right-angle turn. Through the action of the lifting component 7, when the core tray 2 upstream of the conveyor 4 moves to the T-shaped right-angle turn position, the lifting component 7 drives the guide limit block 52 to move upward, thereby releasing the core tray 2. In this embodiment, the lifting component 7 includes a cylinder 71 and two guide rods 72. The cylinder 71 is mounted on the ground or other equipment brackets. The telescopic end of the cylinder 71 is connected to the lower part of the middle position of the guide limit block 52. The top ends of the two guide rods 72 are respectively connected to the bottom ends of the guide limit block 52. The bottom ends of the two guide rods 72 are slidably connected to mounting brackets 73. The guide rods 72 are mounted on other equipment brackets through the mounting brackets 73. Thus, the cylinder 71 can drive the guide limit block 52 to rise and fall.

[0037] The following is combined Figure 5 The working principle of this embodiment will be explained.

[0038] Conveyor 3 conveys the core tray 2, which is unloaded from the previous process, such as... Figure 5 The core tray 2 is located at position 1, and the tabs 11 of the core 1 on the core tray 2 are perpendicular to the direction of movement of the core tray 2.

[0039] When the core tray 2 moves to the docking position between conveyor 3 and conveyor 4, the core tray 2 directly enters the arc-shaped channel under the conveying force of conveyor 3, such as... Figure 5 The core tray 2 at position 2, under the action of the transmission component 6, rotates around the center of the arc surface of the guide limiting block 1 51 as a fulcrum and under the guidance of the arc surface of the guide limiting block 2 52 onto the transmission component 6, and then moves onto the conveyor component 2 4 under the action of the transmission component 6, as follows. Figure 5 Core tray 2 at position 3 in the middle.
