Description

Technical Field

[0001] This application relates to the field of lithium battery production equipment, specifically a cell conveying line. Background Technology

[0002] The battery cell conveyor line is used to transport battery cells. The battery cell conveyor line includes a conveyor belt and two side guards respectively set on both sides of the conveyor belt along its length. The two side guards work together to limit the amount of free movement of the battery cells in the width direction of the conveyor belt, so as to prevent the battery cells from deviating too much along the width direction of the conveyor belt during transport, which would cause the handling mechanism to be unable to accurately clamp the battery cells on the conveyor belt.

[0003] In order to achieve compatible transportation of battery cells of different sizes, in the prior art, a waist-shaped hole extending along the width direction of the conveyor belt is generally provided on the mounting frame of the conveyor belt, and a connecting hole that partially overlaps with the waist-shaped hole is provided on the side guard. The side guard is tightened to the mounting frame by bolts that pass through the connecting hole and the waist-shaped hole.

[0004] Before conveying the battery cells, the installation positions of the two retaining edges need to be adjusted by manually loosening the bolts to ensure that the distance between the two retaining edges matches the size of the battery cells to be conveyed, and then the bolts are tightened again. This manual adjustment of the two retaining edges is cumbersome and inefficient. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a battery cell delivery line, the detailed technical solution of which is as follows:

[0006] A battery cell conveying line includes a mounting frame, a conveyor belt, a conveyor belt drive mechanism, a first side rail, a second side rail, and a side rail drive mechanism, wherein:

[0007] The conveyor belt is mounted on the mounting frame and is used to carry and transport the battery cells. The conveyor belt drive mechanism is mounted on the mounting frame and is used to drive the conveyor belt to transport the battery cells.

[0008] The edge-blocking drive mechanism is mounted on the mounting bracket;

[0009] The first and second guard sides are arranged opposite each other on both sides of the conveyor belt along its length, and both extend along the length of the conveyor belt.

[0010] Both the first and second guard edges are connected to the guard edge drive mechanism, which is configured to drive the first and second guard edges to move closer together or separate along the width direction of the conveyor belt.

[0011] The battery cell conveying line provided in this application has a side-stop driving mechanism that can drive the first side-stop and the second side-stop to move closer together or move apart along the width direction of the conveyor belt, thereby realizing automatic adjustment of the distance between the first side-stop and the second side-stop and improving adjustment efficiency.

[0012] In some embodiments, the sidewall drive mechanism includes a drive assembly and two rows of transmission assemblies; the two rows of transmission assemblies are respectively disposed on a first side and a second side along the length direction of the conveyor belt, and each transmission assembly in each row is spaced apart along the length direction of the conveyor belt; a first sidewall is connected to the movable part of each transmission assembly located on the first side along the length direction of the conveyor belt, and a second sidewall is connected to the movable part of each transmission assembly located on the second side along the length direction of the conveyor belt; the drive assembly is drivenly connected to at least one transmission assembly in each row of transmission assemblies, and the drive assembly is used to drive the first sidewall and the second sidewall to move closer together or move apart along the width direction of the conveyor belt via the transmission assemblies.

[0013] The first retaining edge is supported and driven by multiple transmission components located on the first side of the conveyor belt, ensuring the stability of its movement and preventing it from tilting. Similarly, the second retaining edge is supported and driven by multiple transmission components located on the second side of the conveyor belt, ensuring the stability of its movement and preventing it from tilting.

[0014] In some embodiments, the transmission assembly includes a mounting base, a rotating shaft, and a swing arm, wherein: the mounting base is fixedly connected to the mounting frame; the rotating shaft is rotatably connected to the mounting base along its own axis and is arranged in a vertical direction; a first end of the swing arm is fixedly connected to the rotating shaft, and a second end of the swing arm is rotatably connected to a first stop or a second stop.

[0015] A simple transmission component is provided, which achieves linkage with the first or second stop by swinging the swing arm.

[0016] In some embodiments, a linear bearing is provided inside the mounting base, and the rotating shaft passes through the linear bearing.

[0017] The rotating shaft is threaded through a linear bearing to ensure that it rotates freely and with low friction around its axis, avoiding jamming.

[0018] In some embodiments, the lower ends of the rotating shafts of the two transmission components that are connected to the drive assembly are respectively fixedly mounted with a first gear and a second gear; the drive assembly includes a drive member, a sliding seat, a first rack and a second rack, the sliding seat is slidably connected to the mounting frame and located below the conveying surface of the conveyor belt, and the sliding seat can slide along the length direction of the conveyor belt; the first rack is disposed at the first end of the sliding seat and meshes with the first gear, and the second rack is disposed at the second end of the sliding seat and meshes with the second gear; the drive end of the drive member is connected to the sliding seat, and the drive member is used to drive the sliding seat to slide along the length direction of the conveyor belt.

The rotation direction of the rotating shaft on the first gear is opposite to the rotation direction of the rotating shaft on the second gear.

[0019] When the drive unit drives the sliding block to slide along the length of the conveyor belt, the sliding block drives the rotating shafts of the two transmission components that are connected to the drive unit to rotate via the first and second racks at both ends. This causes the swing arms of the two transmission components to swing, thereby driving the first and second stops to move closer together or separate. At the same time, the swing arms of the remaining two transmission components that are not connected to the drive unit produce adaptive passive swinging under the action of the first and second stops.

[0020] In some embodiments, the sliding seat includes a connecting plate, a first mounting block, and a second mounting block, wherein: the connecting plate is connected to the driving end of the driving member, and the first mounting block and the second mounting block are respectively mounted on both ends of the connecting plate; the first mounting block is slidably connected to the first side wall of the mounting frame via a first slide rail, and a first rack is mounted on the first mounting block; the second mounting block is slidably connected to the second side wall of the mounting frame via a second slide rail, and a second rack is mounted on the second mounting block; both the first rack and the second rack are arranged along the length direction of the conveyor belt.

[0021] By configuring the sliding seat to include a connecting plate, a first mounting block, and a second mounting block, the disassembly and maintenance of the sliding seat are facilitated, and the sliding seat can be smoothly slid along the length of the conveyor belt.

[0023] Another installation method for the first and second guard sides is provided, in which the first and second drive units cooperate to drive the first and second guard sides to slide along the width direction of the conveyor belt, so as to adjust the distance between the first and second guard sides.

[0024] In some embodiments, both the first and second guard sides are provided with a plurality of rollers spaced apart along the length of the conveyor belt.

[0025] By installing rollers on the first and second stops, the first and second stops can be prevented from scratching the battery cells.

[0026] In some embodiments, a plurality of limiting blocks are spaced apart along the length of the conveyor belt, and the power supply core is inserted through the gap between two adjacent limiting blocks.

[0044] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0045] As described in the background section, existing cell conveying lines require manual adjustment of the distance between the two side stops, which is cumbersome and inefficient.

[0046] In view of this, this application provides a cell conveying line that can automatically adjust the distance between two retaining edges, thereby improving adjustment efficiency.

[0047] like Figures 1 to 4 As shown, the battery cell conveying line of this application includes a mounting frame 1, a conveyor belt 2, a conveyor belt drive mechanism 3, a first retaining edge 4, a second retaining edge 5, and a retaining edge drive mechanism 6, wherein:

[0048] The conveyor belt 2 is mounted on the mounting frame 1. The conveyor belt 2 is used to carry and transport the battery cell 100. The conveyor belt drive mechanism 3 is mounted on the mounting frame 1 and is used to drive the conveyor belt 2 to transport the battery.

[0049] The edge-blocking drive mechanism 6 is mounted on the mounting bracket 1.

[0050] The first guard 4 and the second guard 5 are arranged opposite each other on both sides of the length direction of the conveyor belt 2, and both extend along the length direction of the conveyor belt 2. The length direction of the conveyor belt 2 is, for example, the X direction.

[0051] The first retaining edge 4 and the second retaining edge 5 are both connected to the retaining edge drive mechanism 6. The retaining edge drive mechanism 6 is configured to drive the first retaining edge 4 and the second retaining edge 5 to move closer together or separate along the width direction of the conveyor belt 2. The width direction of the conveyor belt 2 is, for example, the Y direction.

[0052] When the battery cell conveying line provided in this application is used to transport battery cells, before the conveying is started, the side guard drive mechanism 6 can drive the first side guard 4 and the second side guard 5 to move closer or separate along the width direction of the conveyor belt 2 according to the specific size of the battery cell to be transported. This makes the distance between the first side guard 4 and the second side guard 5 match the size of the battery cell to be transported, ensuring that the first side guard 4 and the second side guard 5 can cooperate to limit the free movement of the battery cell in the width direction of the conveyor belt 2, and avoid the battery cell from deviating too much along the width direction of the conveyor belt 2 when it is transported on the conveyor belt 2.

[0053] like Figures 1 to 4 As shown, optionally, the sidewall drive mechanism 6 includes a drive assembly 61 and two rows of transmission assemblies 62. The two rows of transmission assemblies 62 are respectively arranged on the first side and the second side along the length direction of the conveyor belt 2, and each transmission assembly 62 in each row is spaced apart along the length direction of the conveyor belt 2. Figures 1 to 4 In the illustrated embodiment, each row of transmission components 62 disposed on the first side and the second side includes 4 transmission components 62. In other embodiments, each row of transmission components 62 may also include 2, 3, 5 or other numbers of transmission components 62.

[0054] The first stop 4 is connected to the movable parts of each transmission assembly 62 located on the first side (e.g., the right side) along the length of the conveyor belt 2, and the second stop 5 is connected to the movable parts of each transmission assembly 62 located on the second side (e.g., the left side) along the length of the conveyor belt 2.

[0055] The drive assembly 61 is connected to at least one of the transmission assemblies 62 in each row of transmission assemblies 62. The drive assembly 61 is used to drive the first sidewall 4 and the second sidewall 5 to move closer or separate along the width direction of the conveyor belt 2 via the transmission assemblies 62 connected to it.

[0056] The first retaining edge 4 is supported and driven by multiple transmission components 62 located on the first side of the conveyor belt 2, ensuring the stability of the first retaining edge 4's movement and preventing it from tilting. Similarly, the second retaining edge 5 is supported and driven by multiple transmission components 62 located on the second side of the conveyor belt 2, ensuring the stability of the second retaining edge 5's movement and preventing it from tilting.

[0057] like Figures 2 to 4 As shown, optionally, the transmission assembly 62 includes a mounting base 621, a rotating shaft 622, and a swing arm 623, wherein: the mounting base 621 is fixedly connected to the mounting bracket 1. The rotating shaft 622 is rotatably connected to the mounting base 621 along its own axis, and the rotating shaft 622 is arranged in a vertical direction. The first end of the swing arm 623 is fixedly connected to the rotating shaft 622, and the second end of the swing arm 623 is rotatably connected to the first stop 4 or the second stop 5.

[0058] By configuring the transmission component 62, it can achieve linkage with the first stop 4 or the second stop 5 through the swing of the swing arm 623.

[0059] Specifically, for the transmission component 62 that is connected to the sidewall drive mechanism 6, the sidewall drive mechanism 6 drives the rotating shaft 622 to rotate, thereby causing the swing arm 623 to swing. During the swinging process, the swing arm 623 drives the first sidewall 4 or the second sidewall 5 to move closer or further apart along the width direction of the conveyor belt 2. For the transmission component 62 that is not connected to the sidewall drive mechanism 6, when the first sidewall 4 or the second sidewall 5 moves closer or further apart along the width direction of the conveyor belt 2, it can drive the swing arm 623 to swing and follow.

[0060] Optionally, a linear bearing is provided within the mounting base 621, and the rotating shaft 622 passes through the linear bearing. By passing the rotating shaft 622 through the linear bearing, it is ensured that the rotating shaft 622 rotates freely and with low friction around its axis, avoiding jamming.

[0061] like Figure 2 and Figure 4 As shown, optionally, a transmission assembly 62 is connected to the drive assembly 61 on the first and second sides along the length of the conveyor belt 2. The lower ends of the rotating shafts 622 of the two transmission assemblies 62 connected to the drive assembly 61 are respectively fixedly mounted with a first gear (not shown in the figure) and a second gear 624.

[0062] The drive assembly 61 includes a drive member 611, a sliding seat 612, a first rack 613, and a second rack 614. The sliding seat 612 is slidably connected to the mounting frame 1 and located below the conveying surface of the conveyor belt 2. The sliding seat 612 can slide along the length of the conveyor belt 1. The first rack 613 is disposed at the first end of the sliding seat 612 and meshes with a first gear. The second rack 614 is disposed at the second end of the sliding seat 612 and meshes with a second gear 624.

[0063] The driving end of the driving member 611 is connected to the sliding seat 612. The driving member 611 is used to drive the sliding seat 612 to slide along the length direction of the conveyor belt 2. When the sliding seat 612 slides, it drives the first gear to rotate via the first rack 613, so as to drive the rotating shaft 622 on the first gear to rotate, and drives the second gear 624 to rotate via the second rack 614, so as to drive the rotating shaft 622 on the second gear 624 to rotate. The rotation direction of the rotating shaft 622 on the first gear is opposite to the rotation direction of the rotating shaft 622 on the second gear 624.

[0064] When the drive unit 611 drives the sliding seat 612 to slide along the length of the conveyor belt 2, the sliding seat 612 drives the rotating shafts 622 of the two transmission components 62 that are connected to the drive unit 61 to rotate via the first rack 613 and the second rack 614 at both ends. This causes the swing arms 623 of the two transmission components 62 to swing, thereby driving the first stop 4 and the second stop 5 to move closer together or move apart. At the same time, the swing arms 623 of the other two transmission components 62 that are not connected to the drive unit 61 to generate adaptive passive swing under the drive of the first stop 4 and the second stop 5.

[0065] like Figure 2 and Figure 4 As shown, optionally, the sliding seat 612 includes a connecting plate 615, a first mounting block 616, and a second mounting block 617, wherein: the connecting plate 615 is connected to the driving end of the driving member 611, and the first mounting block 616 and the second mounting block 617 are respectively mounted on both ends of the connecting plate 615. The first mounting block 616 is slidably connected to the first side wall of the mounting frame 1 via a first slide rail, and a first rack 613 is mounted on the first mounting block 616. The second mounting block 617 is slidably connected to the second side wall of the mounting frame 1 via a second slide rail, and a second rack 614 is mounted on the second mounting block 617. Both the first rack 613 and the second rack 614 are arranged along the length direction of the conveyor belt 2.

[0066] By setting the sliding seat 612 as a split structure consisting of a connecting plate 615, a first mounting block 616 and a second mounting block 617, it is convenient to disassemble and maintain the sliding seat 612, and ensures that the sliding seat 612 can slide smoothly along the length of the conveyor belt 2 to prevent jamming.

[0067] It should be noted that when the drive assembly 61 drives the swing arms 623 of the two rows of transmission assemblies 62 to rotate synchronously, the first stop 4 and the second stop 5 actually slide obliquely horizontally relative to the mounting frame 1 at the same time. Therefore, when the distance between the first stop 4 and the second stop 5 is adjusted by the cooperation of the drive assembly 61 and the transmission assembly 62, the first stop 4 and the second stop 5 will also move relative to the mounting frame 1 along the length direction of the mounting frame 1. However, the amount of movement of the first stop 4 and the second stop 5 in the length direction of the mounting frame 1 is very small and will not affect the normal operation of the first stop 4 and the second stop 5, let alone the normal operation of the battery cell conveying line.

[0068] In addition to the first stop 4 and the second stop 5 being supported and their spacing adjusted by the stop drive mechanism 6 consisting of the drive component 61 and two rows of transmission components 62 in the above embodiments, other implementation methods can also be used to adjust the spacing between the first stop 4 and the second stop 5.

[0069] In another embodiment, both the first guard edge 4 and the second guard edge 5 are slidably connected to the mounting frame 1 and can slide along the width direction of the conveyor belt 2. For example, the mounting frame 1 is provided with several slide rails on both sides along the width direction of the conveyor belt 2, and the slide rails are arranged perpendicular to the conveyor belt 2. The first guard edge 4 and the second guard edge 5 are slidably connected to the corresponding slide rails via sliders.

[0070] The sidewall drive mechanism 6 includes a first drive unit and a second drive unit, wherein: the first drive unit is drivenly connected to the first sidewall 4 and is used to drive the first sidewall 4 to slide along the width direction of the conveyor belt. The second drive unit is drivenly connected to the second sidewall 5 and is used to drive the second sidewall 5 to slide along the width direction of the conveyor belt.

[0071] By cooperating with the first drive unit and the second drive unit to drive the first stop 4 and the second stop 5 to slide along the width direction of the conveyor belt 2, the distance between the first stop 4 and the second stop 5 can be adjusted.

[0072] The first and second drive units can adopt existing linear drive modules with various structures, such as a lead screw drive module consisting of a motor, a lead screw, and a nut.

[0073] like Figure 4 As shown, optionally, both the first guard side 4 and the second guard side 5 are provided with a plurality of rollers 7 spaced apart along the length direction of the conveyor belt 2.

[0074] By installing rollers 7 on the first stop 4 and the second stop 5, the first stop 4 and the second stop 5 can be prevented from scratching the battery cell.

[0075] like Figure 1As shown, optionally, a number of limiting blocks 21 are spaced apart along the length of the conveyor belt 2, with the gap between two adjacent limiting blocks 21 allowing the battery cell to be inserted. This arrangement limits the position of the battery cell 100, preventing it from slipping during transport.

[0076] like Figure 5 As shown, optionally, the conveyor belt drive mechanism 3 includes a drive unit 31, a drive pulley 32, a first gripping pulley 33, a second gripping pulley 34, and a driven pulley 35, wherein the conveyor belt 2 is mounted on the drive pulley 32 and the driven pulley 35. The first gripping pulley 33 and the second gripping pulley 34 are located on both sides of the drive pulley 32, and are used to press the conveyor belt 2 against the circumferential surface of the drive pulley 32 from both sides. The drive unit 31 is used to drive the drive pulley 32 to rotate, so as to drive the conveyor belt 2 to convey.

[0077] By configuring the conveyor belt drive mechanism 3, the conveyor belt 2 can be tensioned on the driving pulley 32 and driven pulley 35 of the conveyor belt drive mechanism 3, thereby improving the conveying stability of the conveyor belt 2 and preventing the conveyor belt 2 from slipping.

[0078] This application provides a sufficiently detailed and specific description. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within its protection scope. The scope of protection claimed in this application is defined by the claims, not by the above descriptions in the embodiments. Without contradiction, some optional components in one embodiment can also be used in another embodiment, and some preferred structures of the same component in one embodiment are also applicable to another embodiment. Furthermore, there may be slight differences in the wording of the names of certain components in different embodiments; these slight differences will not affect the understanding of the technical solution of the present invention by those skilled in the art.
