Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, specifically to a new energy vehicle battery assembly equipment and assembly system. Background Technology

[0002] Automobile assembly mainly consists of four major process workshops: stamping, welding, painting, and final assembly. The task of the final assembly workshop is to assemble all the parts of the vehicle body onto the white body. The number of parts varies from model to model, but is generally over 1,000 (individual parts and assemblies).

[0003] The final assembly workshop mainly consists of assembly line conveyor systems and single-machine equipment performing specific functions. Each workstation is continuous, with product vehicles moving along the conveyor line without stopping at any station. To assemble parts on these moving vehicles, the equipment needs to maintain absolute following and relative stillness. However, each production line has multiple workstations. If any workstation experiences an anomaly, such as an assembly line malfunction requiring pause for troubleshooting, the entire production line stops. This disrupts the equipment's movement relative to the vehicle, making automated assembly impossible. Alternatively, if the vehicle is brought to a standstill before automated operation, maintaining connection with the production line necessitates the establishment of stationary and fast-in / fast-out workstations, resulting in a loss of workstation capacity.

[0004] In summary, existing automobile assembly processes suffer from technical problems such as insufficient automation and low assembly precision. Utility Model Content

[0037] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a new energy vehicle battery assembly equipment and assembly system to solve the technical problems of insufficient automation and low assembly accuracy in the prior art.

[0038] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0039] Firstly, this application provides a new energy vehicle battery assembly device, such as... Figures 1-4 As shown, Figure 1 This is a schematic diagram of the structure of an upper device 2 provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of a battery tray 1 provided in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of a chain conveyor 21 provided in an embodiment of this application; Figure 4 This is a structural schematic diagram of a lifting mechanism 23 provided in an embodiment of this application.

[0040] A new energy vehicle battery assembly equipment includes a battery tray 1, an upper structure device 2, and a transfer device.

[0041] Battery tray 1;

[0042] The upper device 2 includes a chain conveyor 21, a positioning and tightening mechanism 22 and a lifting mechanism 23. The chain conveyor 21 carries the battery tray 1. The positioning and tightening mechanism 22 is located below the chain conveyor 21 and faces the battery tray 1. The lifting mechanism 23 is connected to the chain conveyor 21.

[0043] The transfer device includes a traveling mechanism that carries the lifting mechanism 23.

[0044] This application improves equipment compatibility by using battery tray 1 to accommodate batteries of different sizes on different platforms; then, by using a transfer device to move the superstructure 2, it can move in the same direction as the vehicle body on the lifting device while remaining relatively stationary, which helps improve the assembly accuracy of the superstructure 2; the superstructure 2 is raised and lowered by lifting mechanism 23, which can achieve a large lifting height in a small space, and then the floating mechanism of positioning and tightening mechanism 22 is used for positioning and adjustment, and the battery is tightened after locking, which can effectively solve the error when the battery is docked with the vehicle body, and simultaneously perform automatic tightening of multiple bolts, improving the degree of automation and production efficiency.

[0045] In some embodiments of this application, the battery tray 1 includes a tray frame, a plurality of first supports 11 and a plurality of first positioning pins 12, the tray frame is connected to the chain conveyor 21, and the plurality of first supports 11 and the plurality of first positioning pins 12 are all connected to the tray frame.

[0046] The pallet frame is the main structure of the battery pallet 1, used to support the entire battery. It connects to the chain conveyor 21, allowing the battery pallet 1 to move along the production line. It provides a stable platform for safely carrying the batteries and facilitates their transport on the production line.

[0047] Multiple primary supports 11 are fixed to the pallet frame to support the bottom of the battery, ensuring that the battery is placed stably on the pallet. This multi-point support better distributes the battery weight, reduces stress on the battery structure, and prevents damage during transportation.

[0048] Multiple first locating pins 12 are used to mate with specific holes on the battery to ensure precise positioning of the battery on the tray. This improves assembly accuracy, reduces errors during the assembly process, and allows the battery to be placed quickly and accurately in the correct position, facilitating subsequent assembly work.

[0049] Multi-point support and precise positioning ensure the stability and safety of the battery during assembly. This simplifies battery loading and positioning, reduces manual labor, and improves production efficiency. The design of the precision positioning pins facilitates automated assembly, reduces human intervention, and lowers production costs.

[0050] In some embodiments of this application, the battery tray 1 further includes a plurality of second supports 13 and a plurality of second positioning pins 14, all of which are connected to the frame. At least some of the second supports 13 are distributed around the periphery of the first support 11, and at least some of the second positioning pins 14 are distributed around the periphery of the plurality of first positioning pins 12.

[0051] Multiple second supports 13 are also fixed to the pallet frame, distributed around the perimeter of the first support 11, providing additional support for the battery. This layout can better distribute the weight of the battery, especially for large or heavy batteries, providing a more stable support structure and reducing vibration and displacement of the battery during transportation and assembly.

[0052] Multiple second positioning pins 14 are also fixed to the tray frame. They are distributed around the periphery of the first positioning pin 12 and are used to correspond to the positioning holes on the battery to further ensure the precise positioning of the battery. By adding second positioning pins 14 around the first positioning pin 12, the positioning accuracy of the battery on the tray can be improved. Especially when the battery size is large, this multi-point positioning can reduce assembly errors and improve assembly quality.

[0053] By selecting the first support 11 and the first positioning pin 12, or the second support 13 and the second positioning pin 14 in different positions, batteries of different sizes and models can be accommodated, improving the versatility and flexibility of the equipment. This design allows the battery tray 1 to better adapt to batteries of different sizes and shapes, improving the tray's versatility and adaptability.

[0054] Furthermore, by setting the first support 11 and the first positioning pin 12 as a detachable connection with adjustable position, the positions of the first support 11 and the first positioning pin 12 can be adaptively moved when carrying batteries of different platform sizes, which can further improve compatibility.

[0055] In some embodiments of this application, the chain conveyor 21 includes a conveyor frame 211, a drive motor 212, a drive sprocket 213, and a plurality of driven sprockets 214. The drive motor 212 is connected to the conveyor frame 211, and the output end of the drive motor 212 is connected to the drive sprocket 213. The drive sprocket 213 is connected to the plurality of driven sprockets 214 via a chain.

[0056] The conveyor frame 211 is the main structure of the chain conveyor 21, providing support for other components of the conveyor. The robust frame design ensures the overall stability and durability of the conveyor.

[0057] The drive motor 212 is connected to the conveyor frame 211, and its output end is connected to the drive sprocket 213, providing a power source for the conveyor. The motor drive automates the conveying process, improves production efficiency, and reduces manual operation.

[0058] The drive sprocket 213 is connected to the output end of the drive motor 212. When the motor is working, the drive sprocket 213 rotates, thereby driving the chain to move. The design of the drive sprocket 213 makes the conveying process smooth and easy to control the speed and direction.

[0059] Driven sprockets 214 are connected to drive sprockets 213 via a chain and are distributed on the conveyor frame 211 to ensure smooth chain operation during conveying. Driven sprockets 214 distribute chain tension, reduce chain wear, and extend the service life of the conveyor.

[0060] The chain conveyor 21 operates on the principle of continuous cyclic movement of the chain. After the drive motor 212 starts, it drives the chain to move via the drive sprocket 213. The chain then transmits power through the driven sprocket 214, enabling the battery trays 1 on the entire conveyor line to move continuously and smoothly. The chain conveyor 21 in this equipment connects end-to-end with the battery conveyor line to form a complete production line. The battery conveyor line transports batteries to the chain conveyor 21 in this equipment, where they are then mounted onto the vehicle body. This design allows for automatic transport of the battery trays 1 on the production line without manual intervention.

[0061] In some embodiments of this application, the chain conveyor 21 further includes a pallet positioning pin 215 and a pallet detection sensor 216, both of which are connected to the conveyor frame 211, with the pallet detection sensor 216 facing the battery pallet 1.

[0062] The pallet positioning pin 215 is fixed to the conveyor frame 211 and located at a predetermined position on the battery pallet 1. When the battery pallet 1 is conveyed to a specific position, the positioning pin will insert into the corresponding hole on the pallet to ensure accurate positioning of the pallet during the conveying process.

[0063] The tray detection sensor 216 is connected to the conveyor frame 211 and faces the battery tray 1. The sensor is used to detect the presence, position, and status of the battery tray 1, typically through photoelectric, electromagnetic, or other sensing technologies.

[0064] Physical contact ensures accurate pallet positioning during transport, reducing assembly errors. Real-time pallet position monitoring provides feedback signals for precise adjustments by the conveyor control system. Sensor-collected data can be used for automatic control of conveyor start-up, shutdown, and speed adjustment, enabling highly automated production lines. Real-time monitoring allows for rapid detection and handling of anomalies during transport, reducing downtime due to malfunctions. Precise pallet positioning and real-time status detection improve production line smoothness, thereby increasing overall production efficiency. Detection sensors prevent equipment damage or safety accidents caused by misaligned or out-of-placed pallets.

[0065] In some embodiments of this application, the positioning and tightening mechanism 22 includes a positioning frame 221, a first servo tightening shaft 222, a second servo tightening shaft 223, a first vehicle body positioning pin 224, a second vehicle body positioning pin 225, a first positioning bowl 226, and a second positioning bowl 227. The first servo tightening shaft 222, the second servo tightening shaft 223, the first vehicle body positioning pin 224, the second vehicle body positioning pin 225, the first positioning bowl 226, and the second positioning bowl 227 are all connected to the positioning frame 221 and all face the battery tray 1.

[0066] The positioning frame 221 is the basic structure of the positioning and tightening mechanism 22, used to support and fix other components.

[0067] The first servo tightening shaft 222 and the second servo tightening shaft 223 are connected to the positioning frame 221 and driven by a servo motor to tighten the bolts between the battery and the vehicle body. The servo tightening shafts can precisely control the tightening torque to ensure that the bolts are tightened correctly.

[0068] The first body positioning pin 224 and the second body positioning pin 225 are connected to the positioning frame 221 and are used to cooperate with the corresponding holes on the battery tray 1 to ensure the precise positioning of the battery during the tightening process.

[0069] The first positioning bowl 226 and the second positioning bowl 227 are connected to the positioning frame 221 and are typically designed to cooperate with a specific structure on the battery to further assist in positioning.

[0070] The dual positioning of locating pins and locating cups ensures precise alignment between the battery and the vehicle body, reducing assembly errors. The use of a servo tightening shaft automates bolt tightening, improving production efficiency and consistency. The servo tightening shaft precisely controls the tightening torque, preventing over-tightening or under-tightening and ensuring assembly quality. Different locating pins and locating cups allow the mechanism to adapt to different battery models, improving equipment compatibility. Increased automation reduces assembly time, thereby improving the overall efficiency of the production line.

[0071] In some embodiments of this application, the positioning and tightening mechanism 22 further includes a first floating mechanism 228, a second floating mechanism 229, and a third floating mechanism 220. The first floating mechanism 228 is connected to the positioning frame 221. The first floating mechanism 228, the second floating mechanism 229, and the third floating mechanism 220 are stacked sequentially from top to bottom. The third floating mechanism 220 is connected to the lifting mechanism 23.

[0072] In some embodiments of this application, the first floating mechanism 228 includes a first guide rail, the second floating mechanism 229 includes a second guide rail, and the third floating mechanism 220 includes a rotating shaft, wherein the extension directions of any two of the first guide rail, the second guide rail, and the rotating shaft are perpendicular to each other.

[0073] The first floating mechanism 228, the second floating mechanism 229, and the third floating mechanism 220 are stacked in sequence and connected to the positioning frame 221 and the lifting mechanism 23 to form a multi-layered floating system.

[0074] Each floating mechanism is capable of fine-tuning within its plane to accommodate changes in the position of battery tray 1.

[0075] The first floating mechanism 228 includes a first guide rail, a floating locking cylinder, and a floating detection switch, allowing the positioning frame 221 to drive the servo tightening shaft to move along the guide rail in the X direction to adapt to different positions of the battery tray 1.

[0076] The first guide rail ensures smooth linear movement of the servo tightening shaft, allowing for precise positioning of the bolts on battery tray 1. A floating locking cylinder connected to the floating mechanism on the first guide rail controls the locking and releasing of the floating mechanism. When tightening is required, the cylinder locks the floating mechanism, ensuring the servo tightening shaft remains stable during tightening and does not move due to external forces. After tightening is complete, the cylinder releases, and the floating mechanism returns to its movable state for the next positioning. A floating detection switch detects the position status of the floating mechanism. When the floating mechanism moves to the predetermined position, the detection switch is triggered, sending a signal to the control system. The control system uses these signals to determine whether the floating mechanism has correctly positioned itself, thus deciding whether to continue to the next step.

[0077] The second floating mechanism 229 includes a second guide rail and a floating locking cylinder, which allows the positioning frame 221 to drive the servo tightening shaft to move along the guide rail in the Y direction to further adjust the tightening position.

[0078] The second guide rail ensures precise movement along the Y direction during assembly. A floating lock cylinder is used to control the locking and unlocking of the position on the second guide rail.

[0079] The third floating mechanism 220 includes a rotating shaft, which allows the entire positioning and tightening mechanism 22 to be rotated and adjusted in the vertical Z direction.

[0080] The extension directions of the first guide rail, the second guide rail, and the rotating shaft are perpendicular to each other, providing multi-dimensional adjustment capabilities and ensuring that the positioning and tightening mechanism 22 can adapt to minor deviations in the battery tray 1.

[0081] Multi-dimensional floating and adjustment capabilities significantly improve the precision of battery-vehicle docking. The ability to adapt to battery trays of different sizes and models enhances equipment versatility. Fine-tuning via the floating mechanism reduces assembly errors caused by tray position deviations. Automated floating adjustment reduces manual intervention, improving the automation level of the production line. The floating mechanism design makes the positioning and tightening mechanism 22 more flexible, enabling it to quickly adapt to changes in the production line. Precise and rapid adjustment capabilities help shorten assembly time and improve production efficiency.

[0082] In some embodiments of this application, the lifting mechanism 23 includes a lifting rigid chain 231, a rise-to-position switch 232, a fall-to-position switch 233, a rise overtravel switch 234, and a fall overtravel switch 235. The rise-to-position switch 232 and the fall-to-position switch 233 are respectively located at both ends of the lifting rigid chain 231. The rise overtravel switch 234 is located above the rise-to-position switch 232, and the fall overtravel switch 235 is located below the fall-to-position switch 233.

[0083] The lifting rigid chain 231 is the core part of the lifting mechanism 23, which is used to support the upper device 2 (including chain conveyor 21, positioning and tightening mechanism 22, etc.) and realize its vertical lifting movement.

[0084] The rise-to-position switch 232 is located at the upper end of the lifting rigid chain 231. When the lifting mechanism 23 rises to the predetermined position, the rise-to-position switch 232 is triggered and sends a signal to the control system, instructing the lifting mechanism 23 to stop rising.

[0085] The lowering position switch 233 is located at the lower end of the lifting rigid chain 231. When the lifting mechanism 23 descends to the predetermined position, the lowering position switch 233 is triggered and sends a signal to the control system, instructing the lifting mechanism 23 to stop descending.

[0086] The overtravel switch 234 is located above the rise-to-end switch 232 and is used to detect whether the lifting mechanism 23 has exceeded its lifting limit. If overtravel occurs, the overtravel switch 234 will be triggered, immediately stopping the lifting mechanism 23's upward movement to prevent equipment damage.

[0087] The overtravel switch 235 is located below the descent stop switch 233 and is used to detect whether the lifting mechanism 23 has exceeded its descent limit. If overtravel occurs, the overtravel switch 235 will be triggered, immediately stopping the descent movement of the lifting mechanism 23 to prevent equipment damage.

[0088] The movement range of the lifting mechanism 23 can be precisely controlled by the limit switch and overtravel switch, ensuring it operates within a safe range. The overtravel switch design increases equipment safety, preventing damage due to misoperation or malfunction. The automated control of the lifting mechanism 23 reduces manual intervention and improves the automation level of the production line. The lifting mechanism 23 can be adjusted according to different working height requirements, adapting to various production environments.

[0089] Secondly, this application also provides a new energy vehicle battery assembly system, including a vehicle crane, a battery conveying line, and new energy vehicle battery assembly equipment as described in any embodiment of the first aspect;

[0090] The truck crane is located above the new energy vehicle battery assembly equipment, and the battery conveying line is connected to the new energy vehicle battery assembly equipment.

[0091] In this embodiment, firstly, the battery conveyor line transports the battery tray 1 carrying the battery to the chain conveyor 21 of the assembly equipment along the first direction, and the truck crane carries the vehicle body through the top of the assembly equipment along the second direction, with the first direction and the second direction being perpendicular to each other.

[0092] Next, the transfer device carries the upper device 2 to the bottom of the truck crane and is pre-positioned with the vehicle body, keeping them relatively stationary, and the lifting mechanism 23 rises a certain distance.

[0093] Next, the floating mechanism is unlocked and repositioned to adjust the position of the upper structure 2. After the repositioning is completed, the lifting mechanism 23 continues to rise, with manual calibration during the rise, and the positioning pin enters the vehicle body.

[0094] Finally, the battery reaches its final height, and the manual and / or servo tightening shaft is tightened. The sleeve of the servo tightening shaft is then used to add bolts for the next vehicle. The lifting mechanism 23 descends, the floating mechanism locks, and the transfer mechanism returns to its original position.

[0095] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include:

[0096] This application improves equipment compatibility by using battery tray 1 to accommodate batteries of different sizes on different platforms; then, by using a transfer device to move the superstructure 2, it can move in the same direction as the vehicle body on the lifting device while remaining relatively stationary, which helps improve the assembly accuracy of the superstructure 2; the superstructure 2 is raised and lowered by lifting mechanism 23, which can achieve a large lifting height in a small space, and then the floating mechanism of positioning and tightening mechanism 22 is used for positioning and adjustment, and the battery is tightened after locking, which can effectively solve the error when the battery is docked with the vehicle body, and simultaneously perform automatic tightening of multiple bolts, improving the degree of automation and production efficiency.
