[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0019] For reference Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of this utility model, a mesh pressing tooling conveyor is disclosed, comprising, Conveying mechanism 1 conveys the pressure mesh along the conveying direction (Y-axis direction); A correction mechanism 2 is disposed on the conveying mechanism 1. The correction mechanism 2 includes a slide 25 and a first side push block 22a, a second side push block 22b, a longitudinal push block, and a stop block, all connected to the slide 25. The slide 25 is configured to move along the conveying direction. The first side push block 22a and the second side push block 22b are symmetrically disposed on both sides of the conveying mechanism 1 along the conveying direction, and the first side push block 22a and the second side push block 22b are configured to move towards or away from each other. The stop block is used to block the pressure net along the conveying direction. The longitudinal push blocks are all disposed below the first side push block 22a and the second side push block 22b, and the longitudinal push blocks push the battery cells along the conveying direction.

[0020] The pressing mesh conveyor described in this embodiment has a straightening mechanism 2 mounted on the conveying mechanism 1, integrating pressing mesh conveying and straightening. The process flow is compact and continuous, improving the equipment's production cycle. The first side push block 22a, the second side push block 22b, and the stop block are used to straighten the pressing mesh, while the longitudinal push block is used to straighten the battery cells. After the longitudinal push block is integrated on the slide block 25, the straightening mechanism 2 can straighten both the pressing mesh and the battery cells by pushing the slide block 25 to move. A single mechanism achieves multiple functions, significantly reducing the structural complexity and size of the equipment, and reducing the difficulty and cost of later maintenance.

[0021] In one embodiment of this utility model, the first side push block 22a and the second side push block 22b are used to clamp the pressure mesh from both sides to achieve the alignment of the pressure mesh in the X-axis direction; the longitudinal push block is used to push the battery cell to move along the first direction to achieve the alignment of the pressure mesh in the Y-axis direction. On the conveyor, the height of the battery cell to be welded is lower than the height of the pressure mesh. Therefore, in order to match the height of the longitudinal push block with the battery cell, the longitudinal push block is set to be lower than the first side push block 22a and the second side push block 22b.

[0022] For reference Figure 3 As shown, in one embodiment of the present invention, the correction mechanism 2 further includes a plurality of pressure blocks connected to the slide block 25, and the plurality of pressure blocks are disposed directly above the conveying mechanism 1. The plurality of pressure blocks are used to correct the abnormal height and warped pressure net on the conveyor in the Z-axis direction. The plurality of pressure blocks are symmetrically disposed on both sides of the conveying mechanism 1 along the conveying direction, and are used to correct both sides of the pressure net.

[0023] For reference Figure 3 As shown, in one embodiment of this utility model, the plurality of pressure blocks are all set higher than the stop block, in order to avoid the pressure blocks interfering with the pressure mesh and to ensure that the pressure mesh smoothly abuts the stop block.

[0024] In one embodiment of the present invention, two stop blocks are provided, and the two stop blocks are respectively labeled as first stop block 23a and second stop block 23b. The first stop block 23a is located directly above the first conveyor belt 14, and the second stop block 23b is located directly above the second conveyor belt 13.

[0025] For reference Figure 3 As shown, in one embodiment of this utility model, the conveying mechanism 1 includes a first conveyor belt 14 and a second conveyor belt 13. The first conveyor belt 14 and the second conveyor belt 13 are arranged parallel and spaced apart. The first conveyor belt 14 and the second conveyor belt 13 drive the two ends of the pressing mesh to move through friction. The first conveyor belt 14 and the second conveyor belt 13 are both made of polyurethane. Polyurethane has the characteristics of high temperature resistance and wear resistance, so that the pressing mesh can be conveyed normally in a high temperature environment.

[0026] Furthermore, the conveying mechanism 1 also includes multiple drive wheels 17, driven wheels 15, and a motor 16 for driving the drive wheels 17 to rotate. The drive wheels 17 are used to drive the first conveyor belt 14 and the second conveyor belt 13 to drive the transmission, and the driven wheels 15 are used to ensure the tension of the first conveyor belt 14 and the second conveyor belt 13.

[0027] For reference Figure 1 As shown, in one embodiment of this utility model, two longitudinal push blocks are also included. The two longitudinal push blocks are both disposed below the first conveyor belt 14 and the second conveyor belt 13, and the two longitudinal push blocks are distributed in the transverse direction (X-axis direction) of the first conveyor belt 14 and the second conveyor belt 13. The two longitudinal push blocks can simultaneously apply pushing force to two points of the battery cell to ensure that the battery cell moves smoothly and without tilting during the Y-axis movement, thereby improving the alignment accuracy of the battery cell. The two longitudinal push blocks are respectively labeled as the first longitudinal push block 24a and the second longitudinal push block 24b.

[0028] For reference Figure 1 As shown, in one embodiment of this utility model, a baffle 11 and a nesting space 12 are provided between the first conveyor belt 14 and the second conveyor belt 13. The baffle 11 is provided in the upstream section of the conveyor, and the nesting space 12 is provided in the downstream section of the conveyor. The baffle 11 is set lower than the first conveyor belt 14 and the second conveyor belt 13. Its purpose is to catch the welding strip and various parts that fall from the pressure net due to the loose connection in the upstream section of the conveyor, and to prevent the welding strip and parts from scattering on the ground.

[0029] For reference Figure 4As shown, in one embodiment of the present invention, the correction mechanism 2 further includes a servo drive assembly, which drives the slide 25 to move along the conveying direction. The servo drive assembly includes a lead screw 28, a nut seat 27 threaded onto the lead screw 28, and a motor 29 that drives the lead screw 28 to rotate. The nut seat 27 is connected to the slide 25.

[0030] For reference Figure 4 As shown, the straightening mechanism 2 further includes a slide rail 251 extending along the pressing wire conveying direction, and the slide block 25 is slidably connected to the slide rail 251.

[0031] For reference Figure 3 As shown, in one embodiment of the present invention, the correction mechanism 2 further includes a first driver 26a and a second driver (not shown). The first driver 26a drives the first side push block 22a to move, and the second driver drives the second side push block 22b to move, so that the first side push block 22a and the second side push block 22b can move automatically towards or away from each other. Both the first driver 26a and the second driver are configured as cylinders.

[0032] For reference Figure 3 As shown, in one embodiment of the present invention, the slide 25 is provided with a waste box 4, which is located directly below the conveying mechanism 1. The waste box 4 is used to catch the welding strip and various small parts falling from the pressure mesh.

[0033] For reference Figure 3 As shown, in one embodiment of this utility model, the longitudinal push block is configured as a bearing, the bearing is rotatably connected to the slide 25, and the axis of the bearing extends in the vertical direction. By utilizing the circular surface of the outer ring of the bearing to roll and contact the battery cell, the risk of the battery cell being scratched is reduced, and the integrity of the battery cell is effectively protected.

[0034] For reference Figure 1 As shown, in one embodiment of the present invention, the first pressing block 21a is disposed directly above the first conveyor belt 14, so that the first pressing block 21a precisely presses down and corrects one end of the pressing mesh. Similarly, the second pressing block 21b is disposed directly above the second conveyor belt 13, so that the second pressing block 21b precisely presses down and corrects the other end of the pressing mesh.

[0035] The working principle of the mesh pressing tooling conveyor described in this utility model is as follows: First, the nested conveyor device transports the first battery cell to be welded to the material handling station 3. Then, the servo drive component drives the longitudinal pusher block to move along the Y-axis to push the battery cell to the set position (fine-tuning the position of the battery cell), completing the alignment of the first battery cell. Next, the conveyor transports the first pressure mesh to the material handling station 3 until the pressure mesh is stopped by the stop block, completing the alignment of the pressure mesh in the Y-axis direction. When the height of the pressure mesh is abnormal, the pressure block aligns it in the Z-axis direction. Then, the first side pusher block 22a and the second side pusher block 22b clamp the pressure mesh from both sides, achieving alignment of the pressure mesh in the X-axis direction. Then, the servo drive component pushes the aligned pressure mesh to the set position. Finally, the robot transfers the pressure mesh and the battery cell to the welding station for welding.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
