Description
Technical Field
[0001] This utility model relates to a mechanism for transferring, lifting and positioning module trays on a battery module line. Background Technology
[0002] With the development of new energy vehicles, the production of battery modules is also increasing. Now, assembly line operations are used to improve the assembly efficiency of battery modules: during the assembly process of battery modules, the pallet carrying the battery modules first flows through the main line to the connection point with the branch line, and then enters the branch line for assembly at this station. After the assembly is completed, it enters the main line from the branch line and flows through the main line to the branch line of the next assembly station. In this way, the assembly of each process is completed.
[0003] The existing module pallet transfer and positioning mechanisms from the main line to the branch line are basically composed of two separate devices: a separate transport mechanism and a separate positioning mechanism. These require significant production line space, are difficult to coordinate, and are costly and complex to operate. Meanwhile, to improve battery life, battery modules are becoming increasingly larger and heavier. Existing lifting mechanisms rely on cylinders for direct lifting, which is reliable for lighter modules, but becomes unreliable and unstable when lifting heavier modules (especially those exceeding 500kg). Summary of the Invention
[0004] The problem this invention aims to solve is to provide a transfer, lifting, and positioning mechanism for battery module trays. It achieves both branch line transportation and lifting / positioning functions, significantly reducing the space occupied in the production line layout, decreasing the types and number of mechanisms, facilitating operation, and making module transfer and positioning more convenient. It also achieves excellent linkage, contributing to energy conservation and labor cost savings. Simultaneously, this invention improves the lifting force, thereby enabling the lifting of heavier modules and ensuring stable and reliable lifting.
[0005] The present invention relates to a battery module tray transfer lifting and positioning mechanism, which includes a cylinder lifting assembly, a transfer conveying assembly, and a frame. The transfer conveying assembly includes four support legs and two conveyor lines, which are arranged front and rear, and each conveyor line is fixed to the top of the frame by two support legs. The cylinder lifting assembly is fixed to the top of the frame and located between the front and rear conveyor lines. When the cylinder lifting assembly is in its lowest position, it is lower than the contact surface between the front and rear conveyor lines and the module tray.
[0006] Furthermore, the cylinder lifting assembly includes a base plate, a movable plate, a lifting plate, and at least one cylinder lifting unit. The lifting plate, movable plate, and base plate are arranged in the middle and lower positions. The base plate is fixed on the top of the frame. The cylinder lifting unit connects the base plate, movable plate, and lifting plate. The cylinder lifting unit causes the movable plate to move left and right and the lifting plate to move up and down.
[0007] Furthermore, each cylinder lifting unit includes a lifting cylinder and multiple sliding lifting units. Each sliding lifting unit includes a guide rail slider, a lifting block, and rollers. The lifting cylinder is fixed on the top of the base plate and connected to the side of the moving plate. The guide rail is fixed on the base plate. The slider is fixed on the bottom of the moving plate and connected to the guide rail. The lifting block is fixed on the top of the moving plate. The rollers are fixed on the bottom of the lifting plate, and the lifting block is in contact with the rollers. The upper and lower positions of the lifting block and the slider correspond.
[0008] Furthermore, the surface in contact between the lifting block and the roller consists of two straight sections on the left and right, one low and one high, and a sloping section in the middle; when the lifting cylinder is fully retracted, the roller contacts the low straight section of the lifting block; when the lifting cylinder is fully extended, the roller contacts the high straight section of the lifting block.
[0009] Furthermore, the cylinder lifting assembly also includes two locating pins, which are fixed to the top of the lifting plate and arranged diagonally.
[0010] Furthermore, the cylinder lifting assembly also includes four sets of rectangular guide units. Each guide unit includes a mounting block, a guide rod, and a guide. The mounting block is fixed on the base plate, the guide sleeve is fixed on the movable plate, and the lower end of the guide rod is fixedly connected to the mounting block, while the upper end passes through the guide sleeve.
[0011] Furthermore, the transplanting lifting and positioning mechanism also includes a stop assembly located on the right side of the conveyor line. The stop assembly includes a bracket, a baffle, and two buffer components. The legs of the bracket are fixed to the base plate, and the baffle and buffer components are both fixed to the horizontal plate of the bracket. The two buffer components are located at the front and rear ends of the baffle, and the buffer head of the buffer component is higher than the baffle in the free state.
[0012] Furthermore, the transplanting lifting and positioning mechanism also includes a check valve assembly located at the left end of the conveyor line. The check valve assembly includes a connecting plate and two check valve units, each of which includes a mounting plate, a cylinder, a mounting bracket, and a rotating stop. The connecting plate is fixed on the top of the base plate, and the mounting plate is fixed on the connecting plate. The cylinder is fixedly connected to the bottom of the connecting plate, and its rod end passes through the inner hole of the mounting plate and connects to the mounting bracket. The middle part of the rotating stop is hinged to the mounting bracket, its left end contacts the upper part of the cylinder rod end, and its right end is a free end.
[0013] The advantages of this utility model's transplanting and lifting positioning mechanism are: 1. The cylinder lifting component and the transplanting conveying component are integrated into one mechanism through a frame, meaning that branch line transportation and lifting positioning functions can be achieved on the same mechanism. Under the premise of achieving the same function as existing equipment, it greatly reduces the space occupied by the production line layout, reduces the types and number of mechanisms, facilitates operation, makes the transfer and positioning of modules more convenient, achieves good linkage, and is conducive to energy saving and labor cost saving; 2.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example 1
[0025] from Figure 1 , Figure 2 , Figure 3 , Figure 10 It can be seen that the battery module tray transfer and lifting positioning mechanism of this utility model includes a cylinder lifting assembly 1, a transfer conveying assembly 2, and a frame 3; the transfer conveying assembly 2 includes four support legs 21 and two conveying lines 22, the two conveying lines 22 are arranged front and rear, and each conveying line 22 is fixed to the top of the frame 3 by two support legs 21; the cylinder lifting assembly 1 is fixed to the top of the frame 3 and located between the front and rear conveying lines 22; when the cylinder lifting assembly 1 is in the lowest position, it is lower than the contact surface between the front and rear conveying lines 22 and the module tray 4.
[0026] The present invention relates to a transplanting and lifting positioning mechanism: Frame 3 serves as the skeleton of the entire mechanism, supporting and bearing other components to ensure the stability of the mechanism; Transplanting and conveying component 2 receives and conveys battery module trays along the conveyor line to realize the conversion of battery module trays between the main line and the branch line; Cylinder lifting component 1 lifts the battery module tray after it enters the conveyor line 22 for the next step of assembly. After assembly, the cylinder lifting component descends and separates from the battery module tray, allowing the battery module tray to enter the main line through the conveyor line 22 for circulation.
[0027] The advantages of this utility model of transplanting lifting and positioning mechanism are: both the cylinder lifting component 1 and the transplanting conveying component 2 are fixed on the frame 3 and the cylinder lifting component 1 is located in the middle of the transplanting conveying component 2, realizing the integration of the conveying component and the lifting component. Under the premise of achieving the same function as existing equipment, it greatly reduces the space occupied by the production line layout, reduces the types and number of mechanisms, facilitates operation, realizes linkage, and is conducive to energy saving and saving labor costs. Example 2
[0028] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As can be seen, the transplanting lifting and positioning mechanism of this utility model includes a cylinder lifting assembly comprising a base plate 11, a movable plate 12, a lifting plate 13, and at least one cylinder lifting unit. The lifting plate 13, the movable plate 12, and the base plate 11 are arranged at the top, middle, and bottom. The base plate 11 is fixed on the top of the frame 3. The cylinder lifting unit connects the base plate 11, the movable plate 12, and the lifting plate 13. The cylinder lifting unit causes the movable plate 12 to move left and right and the lifting plate 13 to move up and down.
[0029] After the conveyor line 22 transports the module battery pack tray from the main line to the unit located on the branch line, the cylinder lifting unit drives the moving plate 12 to move to the left, and the lifting plate 13 moves upward to push the module tray away from the conveyor line 22, and the modules on the tray are assembled. After the assembly is completed, the cylinder lifting unit drives the moving plate 12 to move to the right, and the lifting plate 13 moves downward to place the module tray on the conveyor line 22. The conveyor line 22 transports the module tray to the main line, and the main line then transports the module tray to the next station that needs to be assembled.
[0030] When the module tray is relatively light, there is one cylinder lifting unit, which is set on the center line of the front-rear direction of the base plate 11, the moving plate 12 and the lifting plate 13; when the module tray is relatively heavy, there are two or more cylinder lifting units, so that there is enough thrust to push the lifting plate 13 to be lifted reliably. The multiple cylinder lifting units are evenly distributed relative to the center line of the front-rear direction of the base plate 11, the moving plate 12 and the lifting plate 13. Example 3
[0031] from Figure 4 , Figure 5 , Figure 6 , Figure 7 As can be seen, the transplanting lifting and positioning mechanism of this utility model includes: each cylinder lifting unit includes a lifting cylinder 14 and multiple sliding lifting units. Each sliding lifting unit includes a guide rail 15, a slider 16, a lifting block 17, and a roller 18. The lifting cylinder 14 is fixed on the top of the base plate 11 and connected to the side of the moving plate 12. The guide rail 15 is fixed on the base plate 11. The slider 16 is fixed on the bottom of the moving plate 12 and connected to the guide rail 15. The lifting block 17 is fixed on the top of the moving plate 12. The roller 18 is fixed on the bottom of the lifting plate 13 and contacts the roller 18. The upper and lower positions of the lifting block 17 and the slider 16 correspond.
[0032] The lifting cylinder 14 pushes the moving plate 12 to the left. The moving plate 12 moves to the left along the guide rail 15 via the slider 16. The lifting block 17 moves to the left with the moving plate 12, which in turn pushes the roller 18 to move upward, causing the lifting plate 13 to move upward and lift the module tray so that it leaves the conveyor line 22 to facilitate the assembly process.
[0033] When the module tray is relatively light, there is one sliding lifting unit, which is set on the center line of the length direction of the base plate 11, the moving plate 12 and the lifting plate 13; when the module tray is relatively heavy, there are two or more sliding lifting units, so that there is enough thrust to push the lifting plate 13 to be lifted reliably. The multiple sliding lifting units are evenly distributed relative to the center line of the length direction of the base plate 11, the moving plate 12 and the lifting plate 13. Example 4
[0034] from Figure 4 , Figure 5 , Figure 7 As can be seen, the transplanting lifting and positioning mechanism of this utility model consists of two straight sections with varying heights on the left and right and a sloping section in the middle. When the lifting cylinder 14 is fully retracted, the roller 18 contacts the lower straight section of the lifting block 17. When the lifting cylinder 14 is fully extended, the roller 18 contacts the higher straight section of the lifting block 17.
[0035] The lifting block 17 ensures the stability of the lifting plate 13 at its lowest and highest positions by contacting the rollers 18 through the straight sections at both ends. The inclined section in the middle ensures the stability of the lifting and lowering actions, thus ensuring the positional accuracy of the module tray. Example 5
[0036] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 It can be seen that the transplanting lifting and positioning mechanism of this utility model: the cylinder lifting assembly 1 also includes two positioning pins 19, which are fixed on the top of the lifting plate 13 and arranged diagonally.
[0037] The positioning pin 19 is used to determine the position in two-dimensional space to restrict the degree of freedom. When the lifting plate 13 is raised, the positioning pin 19 is inserted into the pin hole under the module tray and reliably connected to the module tray, thereby ensuring that the lifting plate reliably lifts the module tray. Example 6
[0038] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 It can be seen that the transplanting lifting and positioning mechanism of this utility model: the cylinder lifting assembly 1 also includes four sets of rectangular guide units 10. Each set of guide units includes a mounting block 101, a guide rod 102, and a guide sleeve 103. The mounting block 101 is fixed on the base plate 11, the guide sleeve 103 is fixed on the moving plate 12, and the lower end of the guide rod 102 is fixedly connected to the mounting block 101, and the upper end passes through the guide sleeve 103.
[0039] Four guide rods 102 provide guidance for the four corners of the lifting plate 13, ensuring the stability of the lifting plate 13 as it is lifted upward. Example 7
[0040] from Figure 1 , Figure 2 , Figure 3 , Figure 8It can be seen that the transplanting lifting and positioning mechanism of this utility model also includes a stop component 4 set on the right side of the conveyor line 22. The stop component 4 includes a bracket 41, a baffle 42, and two buffers 43. The legs of the bracket 41 are fixed on the base plate 11. The baffle 42 and the buffers 43 are both fixed on the horizontal plate of the bracket 41. The two buffers 43 are located at the front and rear ends of the baffle 42. The buffer head of the buffer 43 is higher than the baffle 42 in the free state.
[0041] When the module pallet is conveyed on the conveyor line 22, it stops conveying when it hits the baffle 42 to ensure that it stops at the position where the assembly operation is required; the module pallet first contacts the buffer 43 for compression, and then contacts the baffle 42 to reduce the impact between the module pallet and the baffle 42. Example 8
[0042] from Figure 1 , Figure 2 , Figure 3 , Figure 9 It can be seen that the transplanting lifting and positioning mechanism of this utility model also includes a check component 5 set at the left end of the conveyor line 22. The check component includes a connecting plate 51 and two check units at the front and rear. Each check unit includes a mounting plate 52, a cylinder 53, a mounting bracket 54, and a rotating stop 55. The connecting plate 51 is fixed on the top of the base plate 11, and the mounting plate 52 is fixed on the connecting plate 51. The cylinder 53 is fixedly connected to the bottom of the connecting plate 51, and its rod end passes through the inner hole of the mounting plate 52 and is connected to the mounting bracket 54. The middle part of the rotating stop 55 is hinged to the mounting bracket 54, its left end is in contact with the upper part of the rod end of the cylinder 53, and its right end is a free end.
[0043] When the module tray needs to enter the mechanism, the rod end of cylinder 53 retracts, causing the mounting bracket 54 and the rotating stop 55 to descend. After the module tray enters through the conveyor line 22 and contacts the stop component 4, the rod end of cylinder 53 extends, causing the mounting bracket 54 and the rotating stop 55 to rise. Since the rotating stop 55 can only rotate towards the cylinder lifting unit, it is blocked by the rod end of cylinder 53 if it moves in the opposite direction, thus preventing the module tray from moving in the opposite direction. After the battery module is assembled, cylinder 53 descends, and the module tray leaves the mechanism through the conveyor line 22.
[0044] The advantages of this utility model's transplanting and lifting positioning mechanism are: 1. The cylinder lifting component and the transplanting conveying component are integrated into one mechanism through a frame, meaning that branch line transportation and lifting positioning functions can be achieved on the same mechanism. Under the premise of achieving the same function as existing equipment, it greatly reduces the space occupied by the production line layout, reduces the types and number of mechanisms, facilitates operation, makes the transfer and positioning of modules more convenient, achieves good linkage, and is conducive to energy saving and labor cost saving; 2. The combination of cylinder and sliding lifting unit improves the lifting force, thereby realizing the lifting of heavier modules and ensuring the stability and reliability of lifting; 3. The combination of stop component and anti-return component ensures the accuracy of the pallet position, thereby ensuring the accuracy of the assembly position.
