Abstract
Description
Technical Field
[0001] This application relates to the field of new energy vehicles, and in particular to a new energy vehicle battery pack assembly line. Background Technology
[0002] New energy vehicles typically use battery packs to power the vehicle. A battery pack usually consists of a battery panel and multiple battery cells. During the assembly of the battery pack, glue is usually injected onto the battery panel. Subsequently, the battery cells are installed on the battery panel. In addition to initially bonding the battery cells, the glue also serves to conduct heat. The battery cells are then fixed to the battery panel by tightening the bolts on the battery cells.
[0003] In the existing technology, battery packs usually require the assembly of battery packs and solar panels. The assembly process usually involves the transfer of battery packs and solar panels. Currently, this transfer and assembly process is mostly carried out in a semi-automated manner, which is done manually and then assembled by equipment. This reduces the assembly efficiency of battery packs. Summary of the Invention
[0004] To improve the assembly efficiency of battery packs, this application provides a new energy vehicle battery pack assembly line.
[0005] The technical solution adopted in this application for a new energy vehicle battery pack assembly line is as follows:
[0006] The system includes an injection execution station, an injection waiting station, a battery pack conveyor line, a battery pack assembly station, and two battery panel transfer vehicles. There are two injection waiting stations, located on either side of the injection execution station. The battery pack assembly station is equipped with a battery pack transfer assembly and a battery panel placement assembly. The battery panel placement assembly includes a transition frame, a drive unit, and a lifting support frame. Assembly positions are located on both sides of the transition frame. The lifting support frame is slidably mounted on the transition frame, and the drive unit is mounted on the transition frame to drive the lifting support frame to move horizontally towards the assembly positions. The lifting support frame supports the injection-completed battery panels located at the assembly positions. The two battery panel transfer vehicles are used to move un-injected battery panels to the injection waiting station for injection and, after injection, move the injection-completed battery panels to the assembly positions. The battery pack transfer assembly is used to move the battery packs from the battery pack conveyor line to the assembly positions and assemble them with the injection-completed battery panels.
[0007] By adopting the above technical solution, the solar panels are first transported by a solar panel transfer vehicle to the glue-applying station. Then, the glue-applying station applies glue to the solar panels on the transfer vehicle. After glue application, the solar panel transfer vehicle moves the glue-applying solar panels to the assembly position at the battery pack assembly station. Then, the drive unit is activated, causing the lifting support frame on the transition frame to move horizontally towards the assembly position. When the lifting support frame passes under the solar panels on the solar panel transfer vehicle, it rises to support the glue-applying solar panels on the transfer vehicle. The battery pack is then transported by the battery pack conveyor line to a position where the battery pack transfer component can clamp it. The battery pack transfer component moves the battery pack from the battery pack conveyor line to the battery plate located at the assembly position to complete the assembly between the battery pack and the battery plate. After that, the lifting support frame retracts and is removed from the battery plate transfer vehicle. The battery plate containing the battery pack is then moved from the assembly position to the next work station by the battery plate transfer vehicle. The whole process realizes the fully automated assembly of the battery pack without the need for manual transfer of the battery pack and battery plate, thereby improving the production efficiency of the battery pack.
[0008] Optionally, the lifting support frame includes a base frame and two support plates. A rack is provided on the base frame, and a gear that meshes with the rack is provided on the drive component. The two support plates are evenly distributed on the base frame, and a lifting component for driving the lifting of the support plate is provided between each support plate and the base frame.
[0009] By adopting the above technical solution, the drive unit is activated, which enables the gear to rotate around its own axis. This allows the gear to mesh with the rack, causing the base frame to slide on the transition frame. This allows the two ends of the base frame to move to the assembly positions on both sides of the transition frame under different rotation directions of the drive motor. This enables the support plate to support the glued solar panels. Furthermore, the lifting component between the support plate and the base frame allows the distance between the support plate and the base frame to be adjusted, allowing the support plate to move smoothly under the glued solar panels.
[0010] Optionally, a positioning frame is provided at the glue injection waiting station. The positioning frame consists of two parallel frames, each equipped with a lifting and positioning component.
[0011] By adopting the above technical solution, a positioning frame is set up at the glue injection waiting station. This allows the lifting and positioning component to lift and position the battery panels on the battery panel transfer vehicle when the battery panel transfer vehicle moves to the glue injection waiting station. This enables the battery panels to be separated from the battery panel transfer vehicle, reducing the impact of the battery panel transfer vehicle on the position of the battery panels. At the same time, it also fixes the position of the battery panels during glue injection, reducing the probability of the battery panels shifting during glue injection.
[0012] Optionally, the lifting and positioning assembly includes a slide rail, support members, lifting members, positioning members, mounting seats, connecting beams, and a lifting mechanism. Two slide rails are provided and are vertically installed at both ends of the frame. The number of mounting seats corresponds to the number of slide rails. The mounting seats are installed on the slide rails. The lifting members are installed on the mounting seats and are used to drive the positioning members to rise. The connecting beam is located between the two mounting seats and is connected to the two mounting seats at both ends. Multiple support members are provided and distributed along the length of the connecting beam. The support members are used to support the solar panels. The lifting mechanism is installed on the frame and located below the mounting seats. The lifting mechanism is used to lift the mounting seats.
[0013] By adopting the above technical solution, the lifting mechanism is used to drive the mounting base to move along the direction of the slide rail, so that the connecting beam and the mounting base can rise, so that the support on the connecting beam can support the solar panel. Then, the positioning component can be lifted by the lifting component, so that the positioning component can position the solar panel, thereby reducing the probability of the solar panel shifting during glue injection.
[0014] Optionally, the lifting mechanism includes a pusher, a connecting rod, and two wedges. The thinner ends of the two wedges face the same direction. The two wedges are respectively installed at both ends of the connecting rod. The pusher is installed on the frame and connected to the connecting rod. Two rollers are provided on the connecting beam. The rollers are located above the wedges and abut against the inclined surfaces on the wedges.
[0015] By adopting the above technical solution, when lifting is required, the pusher is activated, which pushes the connecting rod to move, thereby causing the two wedge blocks to move together. Since the rollers abut against the upper surface of the wedge blocks, when the wedge blocks move, the rollers will rise, thereby raising the height of the connecting beam and the support installed on the connecting beam, so that the support can abut against the solar panel and play a supporting role.
[0016] Optionally, the battery pack transfer assembly includes a truss, a moving module, and a battery pack clamp. The truss is positioned above the transition frame and assembly position. The moving module is mounted on the truss, and the battery pack clamp is mounted on the moving module. The battery pack clamp is used to hold the battery packs on the battery pack conveyor line and to connect the battery panels and the battery packs.
[0017] By adopting the above technical solution, the truss provides an installation base for the mobile module, and the battery pack clamp is set on the mobile module. This allows the mobile module to drive the battery pack clamp to move along the XY axis coordinate system in the horizontal plane, thereby enabling the battery pack clamp to remove the battery pack from the battery pack.
[0018] Optionally, the battery pack fixture includes a first connecting seat, a second lifting component, a second connecting seat, a clamping component, a clamping block, and a screw mounting assembly. The first connecting seat is mounted on the movable module, the second lifting component is mounted on the first connecting seat and connected to the second connecting seat, two clamping components are provided and arranged opposite each other on the second connecting seat, the number of clamping blocks corresponds to the number of clamping components, the clamping blocks can be plugged into the battery pack, and two sets of screw mounting assemblies are provided and respectively mounted on the second connecting seat to realize the connection between the battery pack and the battery plate.
[0019] By adopting the above technical solution, the first connector is installed on the mobile module, so that the first connector can move together with the mobile module. The second lifting component is used to control the height of the second connector. The clamping component arranged on the second connector and the clamping block installed on the clamping component are used to clamp the battery pack, so that the battery pack will not easily fall off during the clamping and moving process. When the battery pack is placed on the battery plate, the screw mounting component tightens the screws on the battery pack to further increase the connection stability between the battery pack and the battery plate.
[0020] Optionally, the screw mounting assembly includes a connecting base three, a lifting component three, and two screw guns. The lifting component three is mounted on the connecting base two and connected to the connecting base three. The connecting base three and the connecting base two are slidably engaged. The two screw guns are respectively mounted on the connecting base three.
[0021] By adopting the above technical solution, the lifting component three is used to control the height of the connecting seat three, so that the connecting seat three will not interfere with the clamping component when the clamping component is in motion, while the screw gun is used to tighten the screws on the battery pack, so that the battery pack can be fixed to the battery plate.
[0022] Optionally, the dispensing station includes a dispensing pump, a robotic arm, a dispensing gun, a mounting plate, a lighting plate, and an industrial camera. The dispensing pump is connected to the dispensing gun, the mounting plate is connected to the robotic arm, and the lighting plate, industrial camera, and dispensing gun are all mounted on the mounting plate.
[0023] By adopting the above technical solution, the transfer arm is used to drive the glue gun to apply glue at different positions on the solar panel, the industrial camera is used to monitor the glue application quality of the glue gun, and the lighting board is used to provide a light source for the industrial camera to capture images of the solar panel, thereby enabling the industrial camera to capture images of the solar panel with higher resolution.
[0024] In summary, this application includes at least the following beneficial technical effects:
[0025] 1. By setting up a glue injection execution station, a glue injection waiting station, a battery pack conveyor line, a battery pack assembly station, and a battery panel transfer vehicle, the battery panel transfer vehicle can move the battery panels to be glued to the glue injection waiting station for glue injection. Subsequently, the battery panel transfer vehicle will transfer the glued battery panels to the assembly station, and the battery pack transfer component will move the battery packs on the battery pack conveyor line to the glued battery panels for connection. The entire process realizes fully automated battery pack assembly without the need for manual transfer of battery packs and battery panels, thereby improving battery pack production efficiency.
[0026] 2. The connecting rod is moved by the pusher, and the wedge block on the connecting rod moves to drive the mounting block. This allows the wedge block to raise or lower the height of the connecting beam, so that the support on the connecting beam can support the solar panel. This method can reduce costs and is less prone to failure compared to directly using a cylinder to lift the panel. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. Example
[0036] This application discloses a new energy vehicle battery pack assembly line, referring to... Figure 1 and Figure 2 It includes a glue injection execution station 1, a glue injection waiting station 2, a battery pack conveyor line 3, a battery pack assembly station 4, and two battery panel transfer vehicles 5. The battery panel transfer vehicles 5 are AGVs, and the battery pack conveyor line 3 is used to transport the battery packs with screws already installed to the battery pack assembly station 4.
[0037] The glue injection station 1 is equipped with a robot arm 44 and a glue injection pump 43. A mounting plate 46 is mounted on the robot arm 44, and an industrial camera 48 and a lighting board 47 are mounted on the mounting plate 46. The glue injection gun 45 is also mounted on the mounting plate 46, and the industrial camera 48 is electrically connected to an external control system. There are two glue injection waiting stations 2, located on both sides of the robot arm 44. When the battery panel transfer vehicle 5 transfers un-glueed battery panels to the glue injection waiting station 2, the robot arm 44 is used to move the glue injection gun 45 to the glue-to-be-injected position on the battery panel. After the glue injection pump 43 is started, the glue is injected into the battery panel through the glue injection gun 45.
[0038] Reference Figure 2 and Figure 3In order to prevent the position of the solar panel from easily shifting during glue injection, thereby causing the glue injection position to shift, a positioning frame 17 is provided at the glue injection waiting station 2. The positioning frame 17 includes two parallel frames 18, with space left between the two frames 18 for the solar panel transfer vehicle 55 to drive in. Each frame 18 is equipped with a lifting and positioning component 19 for positioning the solar panel on the solar panel transfer vehicle 5.
[0039] The lifting and positioning assembly 19 includes a slide rail 20, a support member 21, a lifting member 22, a positioning member 23, a mounting base 24, a connecting beam 25, and a lifting mechanism 26. Two slide rails 20 are provided and vertically installed at both ends of the frame 18. The number of mounting bases 24 corresponds to the number of slide rails 20. The mounting bases 24 are installed on the slide rails 20, allowing them to slide up and down relative to the frame 18. The connecting beam 25 is located between the two mounting bases 24, with both ends of the connecting beam 25 fixedly connected to the two mounting bases 24 respectively. The support member 21 includes a fixed seat and ball bearings. The fixed seat is installed on the connecting beam 25, and the ball bearings... It is installed on a fixed base, with ball bearings abutting against the lower surface of the solar panel. The lifting component 22 is a lifting cylinder, and the positioning component 23 is a positioning pin. The positioning component 23 is installed on the movable end of the lifting component 22. The lifting mechanism 26 is installed on the frame 18 and located below the connecting beam 25. The lifting mechanism 26 lifts the connecting beam 25 so that the support component 21 on the connecting beam 25 can abut against the lower surface of the solar panel. After the support component 21 abuts against the lower surface of the solar panel, the lifting component 22 is activated, thereby pushing the positioning component 23 to insert into the positioning hole on the solar panel, so that the position of the solar panel will not shift during glue injection.
[0040] The lifting mechanism 26 includes a pusher 27, a connecting rod 28, and two wedge blocks 29. The pusher 27 is a cylinder. The length of the connecting rod 28 is parallel to the length of the frame 18. The two wedge blocks 29 are respectively installed at both ends of the connecting rod 28. The thinner ends of the two wedge blocks 29 face the same direction on the connecting rod 28. A roller 30 is set at the position corresponding to the wedge block 29 below the connecting beam 25, which is always in contact with the inclined surface of the wedge block 29. This allows the wedge block 29 to move relative to the roller 30 when the pusher 27 pushes the connecting rod 28 to move from the thinner position of the wedge block 29 to the thicker position of the wedge block 29, thereby raising the height of the connecting beam 25 so that the support 21 on the connecting beam 25 can contact the lower surface of the solar panel.
[0041] Below the wedge block 29 are a slide bar and a slider connected to the frame 18. The slide bar is set on the frame 18, and the length of the slide bar is in the same direction as the length of the connecting rod 28. The slider is slidably set on the slide bar and is connected to the wedge block 29. The slide bar and the slider support the wedge block 29, which prevents the connecting rod 28 from easily bending and deforming when the height of the connecting beam 25 is raised.
[0042] Furthermore, a limit sensing element is also provided on the frame 18. The limit sensing element includes a photoelectric transmitter and a photoelectric receiver. The photoelectric transmitter and the photoelectric receiver are electrically connected to the external control system. The solar panel transfer vehicle 5 is also electrically connected to the external control system. This allows the solar panel transfer vehicle 5 to block the rays emitted by the photoelectric transmitter when its position shifts between the two frames 18. As a result, the photoelectric receiver cannot receive the rays emitted by the photoelectric transmitter, thus enabling the solar panel transfer vehicle 5 to adjust its position between the two frames 18 to ensure the accuracy of the glue injection position.
[0043] Reference Figure 1 , Figure 4 and Figure 5 The battery pack assembly station 4 includes a battery pack transfer assembly 6 and a battery panel placement assembly 7. The battery pack transfer assembly 6 is used to place the battery panels from the battery pack conveyor line 3 onto the assembly 7 for assembly. The battery panel placement assembly 7 includes a transition frame 8, a drive unit 9, and a lifting support frame 10. Assembly positions 11 are provided on both sides of the transition frame 7. The drive unit 9 is a drive motor. The lifting support frame 10 is slidably mounted on the transition frame 8. The lifting support frame 10 includes a base frame 12 and two support plates 13, which are evenly distributed on the base frame 12. A lifting component 16 is provided between the support plates 13 and the base frame 12. 16 is a cylinder. A horizontally mounted rack 14 is provided on the frame 18, and a gear 15 that meshes with the rack 14 is provided on the drive component 9. When the drive component 9 starts to rotate, it can cause the base frame 12 to move towards the assembly position 11 on the transition frame 8. This allows the drive component 9 to drive the frame 18 to move the support plate 13 when the battery panel transfer vehicle 5 moves the battery panel that has been glued to the assembly position 11. The base frame 12 and the support plate 13 on the base frame 12 then move towards the assembly position 11 and pass into the cavity of the battery panel transfer vehicle 5, so that the support plate 13 is located below the battery panel on the battery panel transfer vehicle 5 to support the battery panel.
[0044] Furthermore, a positioning frame 17 is also provided at the assembly position 11, and the frame 18 of the positioning frame 17 is also provided with a positioning mechanism similar to the lifting positioning component 19, thereby increasing the positional accuracy of the solar panel when it is assembled with the battery pack at the assembly position 11.
[0045] The battery pack transfer assembly 6 includes a truss 31, a moving module 32, and a battery pack clamp 33. The truss 31 is positioned above the support plate 13, while the moving module 32 is mounted on the truss 31. The battery pack clamp 33 is mounted on the moving module 32. The moving module 32 enables the battery pack clamp 33 to move on the truss 31. The battery pack clamp 33 is used to clamp the battery packs on the battery pack conveyor line 3 and move the clamped battery packs toward the battery plate that has been glued at the assembly position 11.
[0046] Reference Figure 5 , Figure 6 and Figure 7 The battery pack clamp 33 includes a first connecting seat 34, a second lifting component 35, a second connecting seat 36, a clamping component 37, a clamping block 38, and a screw mounting assembly 39. Both the second lifting component 35 and the clamping component 37 are cylinders. The first connecting seat 34 is mounted on the moving module 32. The second lifting component 35 is mounted on the first connecting seat 34 and connected to the second connecting seat 36. The second lifting component 35 is used to change the distance between the second connecting seat 36 and the first connecting seat 34. Two clamping components 37 are provided and arranged opposite each other on the lower surface of the second connecting seat 36. The number of clamping blocks 38 corresponds to the number of clamping components 37. The clamping blocks 38 are mounted on the movable ends of the clamping components 37 and can connect to the slots on both ends of the battery pack via a plug-in engagement. When it is necessary to transfer the battery pack on the battery pack conveyor line 3, the moving module 32 is activated, driving the first connecting seat 34 to move to the battery pack conveyor line 3. On the battery pack, the second lifting component 35 is activated, causing the first connecting seat 34 to move toward the battery pack on the battery pack conveyor line 3. When the clamping component 37 approaches the battery pack, the clamping component 37 is activated, causing the clamping block 38 to engage with the battery pack. The clamping blocks 38 on the two opposing clamping components 37 then clamp the battery pack. Afterward, the second lifting component 35 retracts, causing the battery pack to rise together with the second connecting seat 36. Subsequently, it is moved by the moving module 32 to the battery plate that has been glued at the assembly position 11, and the second lifting component 35 drives the second connecting seat 36 to descend again, so that the battery pack can be pressed onto the battery plate with a force of 3.5KN-9KN. This allows the glue injected onto the battery plate to be spread out under the pressure of the battery pack. Furthermore, displacement sensors and pressure sensors can be installed on the clamping block 38 to monitor the downward pressure of the battery pack.
[0047] Two sets of screw mounting components 39 are also provided on the second connector 36. The two sets of screw mounting components 39 are respectively installed on both sides of the second connector 36. The screw mounting components 39 include a third connector 40, a third lifting component 41, and two screw guns 42. The third lifting component 41 is a cylinder. The third connector 40 is slidably mounted on the second connector 36. The third lifting component 41 is installed on the second connector 36 and connected to the third connector 40. The third lifting component 41 allows the third connector 40 to slide up and down on the second connector 36. The two screw guns 42 are installed on the third connector 40 and distributed on both sides of the third lifting component 41. When the battery pack is placed on the battery plate, the third lifting component 41 pushes the third connector 40 down, so that the screw guns 42 can tighten the screws on the battery pack. Thus, the battery pack and the battery plate are connected by screws in addition to adhesive bonding, which further increases the connection stability between the battery pack and the battery plate.
[0048] The implementation principle of this application embodiment is as follows: Two battery panel transfer vehicles 5, each carrying un-glued battery panels, enter the gluing waiting station 2. The pusher 27 and lifting member 22 on the positioning frame 17 are activated sequentially to position the battery panels on the battery panel transfer vehicle 5. Then, the robot arm 44 and the glue injection pump 43 are activated together. The robot arm 44 first injects glue into one side of the battery panel, and the glue trajectory on the battery panel is wavy. After the glue injection of the battery panel on that side is completed, the end of the robot arm 44 with the mounting plate 46 is moved to the other side and injects glue into the battery panel on the battery panel transfer vehicle 5 located on that side. The glue-injected battery panel is then moved by the battery panel transfer vehicle 5 to the assembly position 11 on one side of the transition frame 8. The drive member 9 is activated, causing the support plate 13 on the base frame 12 to penetrate into the cavity on the battery panel transfer vehicle 5, thereby being positioned at the assembly position. Below the battery panel after glue application, the lifting component 16 is activated, causing the support plate 13 to abut against the lower surface of the battery panel. Then, the moving module 32 is activated, driving the battery pack clamp 33 to clamp the battery pack on the battery pack conveyor line 3 and move the battery pack from the battery pack conveyor line 3 to above the glue-application battery panel. The battery pack is then installed on the battery panel, and at the same time, the battery pack spreads the glue applied to the battery panel. Then, the screws are tightened by the screw gun 42 to fix the battery pack to the battery panel. This process is repeated so that each battery pack is installed on the battery panel in a symmetrical manner around the central axis of the battery panel. After that, the lifting component 16 retracts, the drive component 9 reverses, and the base frame 12 and support plate 13 are retracted from the battery panel transfer vehicle 5. The battery panel transfer vehicle 5 then removes the battery panel containing the battery pack from the assembly position 11.
[0049] Meanwhile, the battery panel that is being injected with glue on the other side is transferred by the battery panel transfer vehicle 5 to another assembly position 11. The drive unit 9 continuously rotates in the opposite direction, causing the base frame 12 and support plate 13 to move towards the assembly position 11 on that side and repeat the above steps, so that the battery panel and battery pack at the assembly position 11 on that side are assembled and the subsequent steps can be carried out.
[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
