Abstract
Description
Technical Field
[0001] This utility model relates to the field of power battery module disassembly technology, and in particular to a power battery module disassembly mechanism. Background Technology
[0002] To disassemble power battery modules, current technologies often require using specialized lifting tools to smoothly transport the modules to a dedicated disassembly fixture. If the module casing is bolted, it is positioned using a specialized fixture, and then the bolts are removed using insulated tools of the corresponding specifications. The bolts must be stored separately. If the casing is a metal welded or plastic-sealed structure, it must be cut in a closed space using specialized disassembly equipment, with precise control of the cutting depth to prevent damage to the internal cells. If it is an embedded casing, it is disassembled using mechanized disassembly equipment.
[0003] However, the copper busbars and conductive connecting pieces connecting the cells in the module are often fixed by welding, which has a low natural frequency. If the vibration during disassembly causes resonance, it will cause fatigue stress at the weld, gradually leading to cracks or even breakage. At the same time, resonance will also increase the contact resistance, and local abnormal heating may occur during charging and discharging, further damaging the surrounding circuit components. The control circuit board in the module is full of micro-electronic components such as capacitors, resistors, and chips. The impact force generated by resonance can cause the solder joints of these components to crack and the pins to break. It may also shatter the capacitor shell and damage the internal circuit of the chip. Utility Model Content
[0004] The purpose of this utility model is to provide a disassembly mechanism for power battery modules, which solves the problem that the copper busbars and conductive connecting pieces connecting the cells in the module are usually fixed by welding. Their natural frequency is low, and if the vibration during disassembly causes resonance, fatigue stress will be generated at the welding point, and cracks or even breakage will gradually appear. At the same time, resonance will also increase the contact resistance, and local abnormal heating may occur during charging and discharging, which will further damage the surrounding circuit components. The control circuit board in the module is full of micro-electronic components such as capacitors, resistors, and chips. The impact force generated by resonance can cause the solder joints of these components to crack, the pins to break, and may also shatter the capacitor shell and damage the internal circuit of the chip.
[0005] To achieve the above objectives, this utility model provides a power battery module disassembly mechanism.
[0006] The device includes a mounting base, a limit frame fixedly installed on the top of the mounting base, a disassembly and placement platform installed on the inner side of the mounting base, a shock-absorbing component installed at the bottom of the disassembly and placement platform, and a guide rail fixedly installed on one side inside the mounting base.
[0007] The disassembly and placement platform is equipped with a slider fixed on one side, and a first telescopic rod is provided at the bottom of one side of the platform. A spring-damped shock absorber is provided on the outside of the first telescopic rod. The platform is designed to place the power battery module. When hydraulic devices 1 and 2 are activated, they drive hydraulic push rods 1 and 2 to push drill bits 1 and 2 downwards, respectively. When servo motors 1 and 2 are activated, they drive drill bits 1 and 2 to rotate, thus disassembling the power battery module.
[0008] The disassembly and placement platform has a second telescopic rod at its bottom on the other side. A second spring-damped shock absorber is installed on the outer side of the second telescopic rod. During disassembly, the high-speed rotating drill bit one and drill bit two may cause resonance in the power battery module. The first and second telescopic rods are compressed and contracted by the top, which causes the first and second spring-damped shock absorbers to contract, thus damping the power battery module on top of the disassembly and placement platform. The spring-damped shock absorbers are arranged coaxially with the telescopic rods, with the top fixed to the lower end of the disassembly and placement platform and the bottom connected to the bottom of the inner side of the mounting base. This ensures that the compressive force is directly transmitted to the spring-damped shock absorbers, forming a transmission path of "drill bit vibration → module stress → telescopic rod contraction → shock absorber energy consumption".
[0009] The limiting frame has a fixed frame on the top of one side, a hydraulic device on the top of the fixed frame, and a hydraulic push rod at the bottom of the hydraulic device.
[0010] The bottom of the hydraulic push rod is fixedly equipped with a servo motor. The transmission end of the servo motor is fixedly connected to the drill bit. The motor transmission end (output shaft) is machined with a flat keyway, and the tail of the drill bit is correspondingly machined with a keyway. The torque is transmitted through the flat keyway to ensure that the power does not slip when rotating at high speed.
[0011] Among them, a second fixing frame is fixedly installed on the top of one side of the limiting frame, a second hydraulic device is fixedly installed on the top of the second fixing frame, and a second hydraulic push rod is installed at the bottom of the second hydraulic device. The connection design between the bottom of the second hydraulic device and the second hydraulic push rod is designed to ensure "precise pressure transmission + stable installation + coordination with the shock absorption system" to avoid push rod displacement and pressure loss during drilling.
[0012] The bottom of the hydraulic push rod is fixedly equipped with a servo motor, the transmission end of the servo motor is fixedly connected to the drill bit, the transmission end (output shaft) of the motor is machined with a flat keyway, and the tail of the drill bit is correspondingly machined with a keyway. The torque is transmitted through the flat keyway to ensure that the power does not slip when rotating at high speed.
[0013] This utility model discloses a power battery module disassembly mechanism. The disassembly and placement platform is used to place the power battery module. Hydraulic devices one and two are activated, driving hydraulic push rods one and two downwards to move drill bits one and two downwards. Servo motors one and two are activated, driving drill bits one and two to rotate, thus disassembling the power battery module. A keyway is machined on the motor drive end (output shaft), and a corresponding keyway is machined on the drill bit tail. Torque is transmitted through the keyway to ensure no slippage during high-speed rotation. The connection design between the bottom of the hydraulic device and the hydraulic push rods is designed to ensure "precise pressure transmission + stable installation + coordination with the shock absorption system," preventing push rod misalignment and pressure loss during drilling.
[0014] This utility model discloses a power battery module disassembly mechanism. Through the installation of shock-absorbing components, during disassembly, the high-speed rotating drill bit one and drill bit two may cause resonance in the power battery module. The first and second telescopic rods are compressed and contracted by the top, which drives the spring damping shock absorbers one and two to contract, thereby damping the power battery module on the top of the disassembly and placement platform. The spring damping shock absorbers are arranged coaxially with the telescopic rods, with the top fixed to the lower end of the disassembly and placement platform and the bottom connected to the bottom of the inner side of the mounting base, ensuring that the compressive force is directly transmitted to the spring damping shock absorbers, forming a transmission path of "drill bit vibration → module stress → telescopic rod contraction → shock absorber energy consumption".
