Description

Technical Field

[0001] This invention relates to the field of new energy technology, and in particular to a double-row modular stacking tray. Background Technology

[0002] The global energy and environmental problems caused by the automotive industry have made the development of new energy vehicles an urgent task for the world today. New energy vehicles are an effective way to solve the energy and environmental problems faced by automobile transportation. With the continuous advancement of green and environmentally friendly themes, the use of electric vehicles is increasing year by year. The battery module is an important component of the electric vehicle power system, and the tray is the part in the battery module used to support the battery cells.

[0003] For example, in the manufacturing process of new energy battery packs, multiple cells are usually assembled together and the overall structure is fixed by side panels and end plates. Currently, the most common method is to weld the side panels and end plates together.

[0004] Therefore, before battery pack welding, multiple battery cells, side panels, and end plates need to be transported to the welding station in a specified ratio for battery pack fabrication. Currently, battery cell transportation uses a stacking process as a crucial step in the module forming process. During cell stacking, the cells are typically automatically fed and sorted, fixed with fixtures, and then transported to a conveyor belt. A module robot identifies the orientation of the cells by rotation, and then places them on a carrier for secondary stacking. This process is repeated until the cells are fully stacked. After stacking, the corresponding side panels and end plates are transported to the welding station via robots or other conveyor devices for positioning and welding. This method of stacking cells and separately transporting side panels and end plates severely reduces automation and results in low production efficiency. Summary of the Invention

Detailed Implementation

[0019] 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 described are not intended to limit the present invention.

[0020] Reference Figure 1-4As shown, the double-row module stacking tray of the present invention includes four parts: a base assembly 1, an end plate clamping mechanism 2, a middle end plate positioning mechanism 3, and a side plate positioning unit 4. The base assembly 1 serves as a support component for the tray and is provided with a plurality of battery cells. The base assembly 1 is placed on a conveyor line to realize the conveying of battery cells and side plates. The end plate clamping mechanism 2 consists of two symmetrically arranged end plates, which are respectively located at both ends of the long side of the base assembly 1 and are used for driving the tray. The end plate clamps the battery cell on the base assembly 1; there are two symmetrically arranged middle end plate positioning mechanisms 3, which are located at the middle axis position of the two end plate clamping mechanisms 2. The middle end plate positioning mechanisms 3 are fixedly installed on the base assembly 1, and the two middle end plate positioning mechanisms 3 are used to position the middle end plate; there are two symmetrically arranged side plate positioning units 4, which are installed on the base assembly 1. The two side plate positioning units 4 are located at both ends of the short side of the base assembly 1, and the side plate positioning units 4 are used for side plate positioning.

[0021] The side plate positioning unit 4 includes a first side plate positioning mechanism 41, a second side plate positioning mechanism 42, and a third side plate positioning mechanism 43. The first side plate positioning mechanism 41, the second side plate positioning mechanism 42, and the third side plate positioning mechanism 43 are all fixedly mounted on the base assembly 1 and are located on the same straight line. The first side plate positioning mechanism 41 and the third side plate positioning mechanism 43 are symmetrically arranged at both ends of the long side of the base assembly 1. The second side plate positioning mechanism 42 is located between the first side plate positioning mechanism 41 and the third side plate positioning mechanism 43. The first side plate positioning mechanism 41, the second side plate positioning mechanism 42, and the third side plate positioning mechanism 43 are used to position and clamp the side plate. The purpose of setting up side panel positioning mechanism 1 41, side panel positioning mechanism 2 42 and side panel positioning mechanism 3 43 to position a side panel is that side panel positioning mechanism 1 41 and side panel positioning mechanism 2 42 position the two ends of the side panel. Since the side panel has a certain length, in order to prevent the side panel from deforming, side panel positioning mechanism 3 43 is added at the middle position to position the middle position of the side panel.

[0022] In the above structure, the base assembly 1 includes a rectangular steel frame 11, a supporting base plate 12, four vertical supporting plates 13, and a cell module placement plate 14. The supporting base plate 12 is fixedly mounted on the upper surface of the rectangular steel frame 11. The four vertical supporting plates 13 are arranged in a rectangular array on the supporting base plate 12. The cell module placement plate 14 is fixedly mounted on the four vertical supporting plates 13 and is used to place the cell. The rectangular steel frame 11 is welded from several horizontally and vertically intersecting rectangular steel pipes. The supporting base plate 12 is welded to the rectangular steel frame 11. Since the rectangular steel frame 11 moves with the conveyor line, the lower ends of the steel pipes constituting the rectangular steel frame 11 are all connected with wear-resistant strips 111. The function of the wear-resistant strips 111 is to protect the bottom of the rectangular steel frame 11 from friction by the conveyor line. A blocking block 112 is provided at the side wall where the rectangular steel frame 11 and the wear-resistant strip 111 connect. The blocking block 112 is used to brake the pallet by interacting with a stopper. Several buffer blocks 118 are provided on the side walls around the rectangular steel frame 11. When the pallet stops at a designated workstation, the buffer blocks 118 interact with a buffer to slowly stop the pallet. A rotating shaft 113 is provided at each of the four corners of the rectangular steel frame 11. The lower end of each rotating shaft 113 is connected to a bearing follower 114. The bearing follower 114 is used to guide the pallet's movement along the conveyor line. The bearing follower 114 is installed at the four corners of the rectangular steel frame 11, serving as a guide as the pallet runs on the line.

[0023] In the above structure, the rectangular steel frame 11 is provided with a positioning sleeve 115, and the positioning sleeve 115 is provided with a positioning hole 116. When the pallet stops at the designated position and needs to be lifted for corresponding processing, the positioning pin on the lifting device is inserted into the positioning hole 116, thereby realizing the positioning connection between the lifting device and the rectangular steel frame 11 and preventing the rectangular steel frame 11 from shifting position.

[0024] In the above structure, the rectangular steel frame 11 is provided with a FRAD card 117, which is used to control the position of the control system monitoring the pallet on the conveyor line.

[0025] Reference Figure 5 , 6As shown, the cell module placement plate 14 is a rectangular flat plate, and a boss 141 is provided on the upper surface of the cell module placement plate 14. The boss 141 is arranged along the length direction of the cell module placement plate 14, and the cell contacts the boss 141. This avoids direct contact between the cell and the cell module placement plate 14, reducing the contact area between the cell and the cell module placement plate 14, so that the cell can be moved when the end plate clamping mechanism 2 pushes the cell through the end plate. The cell module placement plate 14 has two rectangular grooves 142 on each of its short sides. The rectangular grooves 142 are designed to match the end plate clamping mechanism 2 and avoid interference with it. The side wall of the long side of the cell module placement plate 14 has a notch, and the middle end plate positioning mechanism 3 is located at the notch to position the middle end plate.

[0026] Reference Figure 7 , 8 As shown, the end plate clamping mechanism 2 includes a lower mounting plate 21, a first upright plate 22, a second upright plate 23, a moving plate 24, a guide rod 25, a first spring 26, a first linear guide rail 27, a first slider 28, a support plate 29, and a first positioning pin 210. The lower mounting plate 21 is fixedly mounted on the base assembly 1. The first upright plate 22 and the second upright plate 23 are symmetrically and parallelly fixedly mounted on the lower mounting plate 21. The two ends of the guide rod 25 are respectively connected to the first upright plate 22 and the second upright plate 23. The spring 26 is sleeved on the guide rod 25, and the two ends of the spring 26 abut against the vertical surfaces of the upright plate 22 and the moving plate 24, respectively. The linear guide rail 27 is fixedly mounted on the lower mounting plate 21. The slider 28 is fixedly connected to the moving plate 24, and the slider 28 is slidably connected to the linear guide rail 27. The support plate 29 is fixedly connected to the moving plate 24. The support plate 29 is provided with positioning pins 210 on both sides of the base assembly 1. A stop 211 is provided in the middle of the support plate 29. The stop 211 is a right-angle plate. One right-angle side of the stop 211 is fixedly connected to the support plate 29, and the other right-angle side of the stop 211 is connected to the end plate. Two rectangular extension plates 212 are provided on the side of the support plate 29 near the center of the base assembly 1. The two rectangular extension plates 212 are arranged in parallel and there is a certain distance between them. A partition 213 is provided on the upper surface of the rectangular extension plate 212. The partition 213 is a rectangular flat plate, and a rectangular through groove 214 is provided in the middle of the partition 213, which runs through the length of the partition 213. Therefore, two steps 215 are formed on the long side of the partition 213. The cross-sectional area of ​​the rectangular extension plate 212 is smaller than the cross-sectional area of ​​the rectangular groove 142. The rectangular extension plate 212 is placed inside the rectangular groove 142. The upper end face of the second step 215 and the upper end face of the first boss 141 are on the same plane. In this way, when the battery cell is placed on the upper end face of the second step 215 and the upper end face of the first boss 141, the battery cell can be kept flat.

[0027] Initially, the tray 29 is pulled towards the edge of the base assembly 1, thereby increasing the distance between the two trays 29. After the battery cell is placed on the battery cell module placement plate 14, the lower end of a portion of the battery cell is placed on the partition plate 213. The tray 29 is released, and under the elastic restoring force of the spring 26, the tray 29 is pushed towards the center of the base assembly 1, thereby pushing the battery cell to fit against the middle plate placed in the center of the base assembly 1, thus achieving the positioning and clamping of the battery cell.

[0028] Both the first upright plate 22 and the second upright plate 23 are provided with limiting bolts 221, which are used to limit the extreme positions of the moving plate 24. The lower mounting plate 21 is provided with a positioning indexing pin 211, which is used to limit the slider 28 on the linear guide rail 27 and prevent the slider 28 from falling off the linear guide rail 27.

The indexing pin 2 417 is mounted on the position adjusting block 413, and the head of the indexing pin 2 417 passes through the position adjusting block 413 and connects with the fixing block 2 416 to achieve locking and positioning.

[0035] In the above structure, the fixing block 416 has several pin holes 418, which are aligned on the same straight line. The head of the indexing pin 417 is inserted into the pin hole 418 to lock the position adjusting block 413. Based on the side plate length, the position adjusting block 413 is moved to a suitable position on the linear guide rail 411, and then the head of the indexing pin 417 is inserted into the pin hole 418 to lock the position adjusting block 413.

[0036] In the above structure, a right-angle notch 419 is provided at the corner position opposite to the center of the base assembly 1 of the second stop 414. The second positioning pin 415 is located within the right-angle notch 419, and the end of the side plate is provided within the right-angle notch 419. When the side plate is placed, the end of the side plate fits perfectly into the right-angle notch 419. At the same time, a positioning hole is provided on the end plate, and the second positioning pin 415 is inserted into the positioning hole to ensure that the end of the side plate is stably fixed on the first side plate positioning mechanism 41 and the second side plate positioning mechanism 42.

[0037] Reference Figure 15 , 16 As shown, the side plate positioning mechanism 43 includes a support 431, a spring mounting plate 432, a pressure block 433, a spring 434, and two adjusting screws 435. The support 431 is fixedly mounted on the base assembly 1. The spring mounting plate 432 is fixedly connected to the support 431. The support 431 has a through hole 436. The pressure block 433 passes through the through hole 436. One end of the spring 434 is connected to the spring mounting plate 432, and the other end of the spring 434 is connected to the pressure block 433. One end of the adjusting screw 435 is connected to the pressure block 433, and the other end of the adjusting screw 435 passes through the spring mounting plate 432. The support 431 is used to mount the side plate, and the pressure block 433 is in contact with the side wall of the side plate. The support 431 is T-shaped, and its upper end is provided with a side plate limiting groove 437. A side plate is provided inside the side plate limiting groove 437. The side plate limiting groove 437 is connected to the through hole 436. One end of the pressure block 433 is located in the side plate limiting groove 437 and contacts the side plate. By tightening the adjusting screw 435, the pressure block 433 overcomes the pressure of the spring 434, thereby creating a gap between the pressure block 433 and the inner side of the support 431, ensuring that the side plate 300 is placed in the side plate limiting groove 437.

[0038] The operating principle of the double-row modular stacking pallet of the present invention on the production line is as follows: 1. The pallet runs on the line. When it reaches the end plate placement station, the lifting and positioning mechanism lifts the pallet and positions it. The robot arm places one middle end plate 200 onto the middle end plate positioning mechanism 3 and two end plates 100 onto the positioning pin 210. After completion, the lifting and positioning mechanism lowers and puts the pallet down. 2. When the pallet moves to the cell placement station, the lifting and positioning mechanism lifts the pallet and positions it. Then the end clamping mechanism opens, and the robot arm puts in the cells 400 in sequence. Then the two end plate clamping mechanisms 2 close, and the lifting and positioning mechanism descends to release the cells. 3. When the pallet moves to the side plate placement station, the lifting and positioning mechanism lifts the pallet up and positions it. Then, the robot arm sequentially places the two side plates 300 onto the side plate positioning mechanism 1 41, the side plate positioning mechanism 2 42, and the side plate positioning mechanism 3 43. Finally, the lifting and positioning mechanism lowers to release the pallet.

[0039] 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 scope of protection of this invention.
