Description

Technical Field

[0001] This application relates to the technical field of mechanical equipment, and particularly relates to a power lithium battery process plunger screwing equipment and a screwing process method. Background Art

[0002] In recent years, the new energy industry has developed rapidly and become a key force in addressing global climate change and energy crises. In this process, new energy batteries, especially energy storage technologies such as power lithium batteries and solid-state batteries, have played a crucial role. These batteries are not only the power sources for clean transportation such as electric vehicles but also play a role in balancing power supply and improving energy utilization efficiency in new energy grid energy storage systems. The development of new energy batteries has promoted the technological progress and scale expansion of the new energy industry and provided strong support for achieving the green energy transformation.

[0003] With the development of new energy batteries, the requirements for their performance and safety are also getting higher and higher. Since the electrolyte of new energy batteries is water-absorbent and easily crystallizes, it is necessary to evacuate the air and block the injection holes with process plungers before formation after injection, and then remove the process plungers during formation, and then evacuate the air and insert the process plungers again after formation. Therefore, the insertion and removal of process plungers is an indispensable process. In the traditional process, the insertion and removal of process plungers are carried out manually, which not only takes a long time, is laborious and time-consuming, but also has a high cost and a high error rate. Therefore, there is an urgent need for a device to realize the intelligent insertion and removal of process plungers to solve the problems of low efficiency and high cost in the traditional process. Summary of the Invention

[0004] In view of this, this application provides a power lithium battery process plunger screwing equipment and a screwing process method to realize the intelligent insertion and removal of process plungers and solve the problems of low efficiency and high cost in the traditional process.

[0006] In the first aspect of this application, a power lithium battery process plunger screwing equipment is provided. The screwing equipment acts on a power lithium battery and is used to install a process plunger at the injection port of the power lithium battery to control the electrolyte injected into the power lithium battery. The screwing equipment at least includes: a separation module, a material receiving module, a vibrating plate discharging module, a lifting and positioning conveying module, and a plugging module. Among them, the separation module is connected to the material receiving module, and the separation module is connected to the vibrating plate discharging module. The material receiving module is fixed on the lifting and positioning conveying module.

[0007] The vibrating plate discharging module is used to detect whether there is a process plunger in the vibrating plate and control the process plunger to be conveyed from the vibrating plate to the separation module when there is a process plunger.

[0008] After receiving the process plunger, the separation module conveys the process plunger to the material receiving module through the process plunger conveying hose;

The plugging module grasps the process plungers based on the position of the material frame and installs the process plungers into the liquid injection port of the power lithium battery. First, through the collaborative work of multiple modules of the screwing equipment, the intelligent screwing of process plungers is realized, solving the problems of low efficiency and high cost in the traditional process, saving time and cost, and improving production efficiency.

[0180] Specific embodiments are given below to introduce the technical solutions of this application in detail.

[0181] Figure 1 It is a schematic structural diagram of the first embodiment of the plunger screwing device for the power lithium battery process provided by this application. Please refer to Figure 1 , for the device provided in this embodiment, the screwing device acts on the power lithium battery and is used to install a process plunger at the liquid injection port of the power lithium battery to control the electrolyte injected into the power lithium battery; the screwing device at least includes: a separation module 3, a material receiving module 4, a vibrating disk discharging module 5, a lifting and positioning conveying module 6, and a plugging module 7; wherein, the separation module 3 is connected to the material receiving module 4, and the separation module 3 is connected to the vibrating disk discharging module 5; the material receiving module 4 is fixed on the lifting and positioning conveying module 6;

[0182] The vibrating disk discharging module 5 is used to detect whether there is a process plunger in the vibrating disk, and when there is a process plunger, control the process plunger to be conveyed from the vibrating disk to the separation module 3;

[0183] After receiving the process plunger, the separation module 3 conveys the process plunger to the material receiving module 4 through a process plunger conveying hose;

[0184] After receiving the process plunger, the material receiving module 4 places the process plunger at the grasping position so that the plugging module 7 can grasp the process plunger;

[0185] The lifting and positioning conveying module 6 conveys the process plunger to the position to be operated based on the frame loading and performs lifting and positioning on the frame to determine the position of the frame;

[0186] The plugging module 7 grasps the process plunger in the frame based on the position of the frame and installs the process plunger at the liquid injection port of the power lithium battery.

[0187] Specifically, the power lithium battery process plunger screwing and installing device acts on the power lithium battery. It is used to install the process plunger at the liquid injection port of the power lithium battery to control the electrolyte injected into the power lithium battery, and at the same time, pull out the process plunger after the liquid injection is completed. The power lithium battery process plunger screwing and installing device at least includes a separation module 3, a material receiving module 4, a vibrating disk discharging module 5, a lifting and positioning conveying module 6, and a plugging module 7. Among them, the vibrating disk discharging module 5 is used to control the process plunger to be conveyed from the vibrating disk to the separation module 3 when there are process plungers in the vibrating disk. The separation module 3 conveys the received process plungers to the material receiving module 4 through the process plunger conveying hose. The material receiving module 4 places the received process plungers at the grasping position. The lifting and positioning conveying module 6 conveys the process plungers to the position to be operated based on the material frame, and determines the position of the material frame by means of lifting and positioning. The plugging module 7 grasps the process plungers based on the position of the material frame and installs the process plungers at the liquid injection port of the power lithium battery.

[0188] Optionally, the power lithium battery process plunger screwing and installing device at least further includes an upper cover module 2, and the upper cover module 2 at least includes an alarm indicator light;

[0189] Optionally, the vibrating disk discharging module 5 at least includes a vibrating disk, a vibrating disk bottom plate, a detection optical fiber, and a detection optical fiber mounting plate; among them, the detection optical fiber is fixed on the detection optical fiber mounting plate, and the vibrating disk is fixed on the vibrating disk floor.

[0190] In specific implementation, in combination with the above description, the vibrating disk generates process plungers through electromagnetic vibration or mechanical vibration. The detection optical fiber detects the vibrating disk in real time. When the detection result is that there are process plungers in the vibrating disk, the vibrating disk conveys the process plungers to the separation module 3; when the detection result is that there are no process plungers in the vibrating disk, the alarm indicator light in the upper cover module 2 flashes and sends an alarm signal.

[0191] Optionally, the separation module 3 at least includes a process plunger conveying hose, an opposed fiber optic, a fiber optic mounting bracket, a feeding docking plate, a cylinder connecting plate, a feeding cylinder, a blowing joint, a blowing joint mounting plate, and a mounting main board; among them, the process plunger conveying hose and the feeding cylinder are fixed on the mounting main board, the opposed fiber optic is fixed on the fiber optic mounting bracket, the blowing joint is fixed on the blowing joint mounting plate, and the feeding docking plate is fixed on the cylinder connecting plate.

[0192] It should be noted that the optical fiber mounting bracket includes at least an L-shaped optical fiber mounting bracket and a Z-shaped optical fiber mounting bracket; among them, the L-shaped optical fiber mounting bracket is composed of two mutually perpendicular parts, presenting a right-angle structure, which is fixed by using a corner or a wall surface to firmly fix the optical fiber and prevent the optical fiber from moving or vibrating; the Z-shaped optical fiber mounting bracket is composed of a first planar section, a second planar section, and a third planar section. Among them, the first planar section is parallel to the mounting surface and is used to guide the starting path of the optical fiber; the second planar section is perpendicular to the first planar section and is used to change the direction of the optical fiber; the third planar section is parallel to the mounting surface and is used to guide the continuing path of the optical fiber.

[0193] For the device provided in this embodiment, by setting the optical fiber mounting bracket as L-shaped and Z-shaped, among which, the L-shaped optical fiber mounting bracket has a simple structure and provides a stable and simple installation method; the Z-shaped optical fiber mounting bracket has a complex structure and provides high installation flexibility and adjustment ability. Different installation requirements are met, the stability and reliability of optical fiber installation are improved, and at the same time, the optical path is optimized and signal loss is reduced. It can not only achieve simple and direct opposed detection, but also achieve complex path detection.

[0194] In specific implementation, after the separation module 3 receives the process plunger, the opposed optical fibers detect the feeding docking plate in real time. When the detection result is that there is a process plunger in the feeding docking plate, the feeding air cylinder moves horizontally to control the feeding docking plate to move to the blowing position, and the blowing joint blows the process plunger, so that the process plunger enters the process plunger conveying hose and is conveyed to the receiving module 4 through the process plunger conveying hose; when the detection result is that there is no process plunger in the feeding docking plate, the alarm indicator light in the upper cover module 2 flashes and sends an alarm signal.

[0195] Optionally, the receiving module 4 at least includes a material distribution air cylinder, a material distribution air cylinder mounting plate, an optical fiber sensor, an optical fiber mounting bracket, a receiving air cylinder, and a receiving air cylinder mounting plate; among them, the material distribution air cylinder is fixed on the material distribution air cylinder mounting plate, the optical fiber sensor is fixed on the optical fiber mounting bracket, and the receiving air cylinder is fixed on the receiving air cylinder mounting plate.

[0196] In specific implementation, after the receiving module 4 receives the process plunger, the optical fiber sensor detects the process plunger grasping position. When the detection result is that there is a process plunger at the process plunger grasping position, control the material distribution air cylinder to move to the process plunger grasping position and control the receiving air cylinder to rise so that the receiving air cylinder is docked with the material distribution air cylinder. When the process plunger reaches the process plunger grasping position through the process plunger conveying hose, control the receiving air cylinder to descend and control the material distribution air cylinder to move away from the process plunger grasping position; when the detection result is that there is no process plunger at the process plunger grasping position, the alarm indicator light in the upper cover module 2 flashes and sends an alarm signal.

[0197] Optionally, the lifting and positioning conveying module 6 at least includes a lifting unit, a conveying unit, and a positioning unit.

[0198] In specific implementation, the conveying unit loads the process plunger through a material frame and conveys the material frame to the area to be operated. The positioning unit monitors the position of the material frame in real time. When the position of the material frame is detected, the lifting unit lifts and positions the material frame, that is, by controlling the lifting of the lifting motor, the material frame is positioned to determine the position of the material frame.

[0199] Optionally, the plugging module 7 includes at least an electric rotating gripper and a laser displacement sensor.

[0200] In specific implementation, the electric rotating gripper moves towards the material frame based on the position of the material frame. The laser displacement sensor detects the distance between the electric rotating gripper and the position of the material frame in real time during the movement. When the distance is less than a preset threshold (the preset threshold is set according to actual needs and is not limited in this embodiment), the Z-axis rotation speed and the Z-axis direction displacement of the electric rotating gripper are jointly controlled to grab the process plunger in the material frame and install the process plunger at the liquid injection port of the power lithium battery.

[0201] When the electric rotating gripper moves, the material frame allows it to move to a specified position. In order to quickly move to the specified position, the initial moving direction and the initial moving speed of the electric rotating gripper are set. Among them, the initial moving direction only includes the component in the x-axis direction; that is, at the initial moment, it only moves quickly on the horizontal plane to avoid affecting the installation or operation of other components below after descending, saving the layout space of the components and improving the utilization rate; then, after the electric rotating gripper moves, the laser displacement sensor detects the distance between the electric rotating gripper and the material frame in real time, and adjusts the real-time moving direction and the real-time moving speed of the electric rotating gripper based on the real-time detected distance. Among them, the real-time moving direction includes the components in the x, y, and z-axis directions. That is to say, at this time, the electric rotating gripper moves in a parabolic shape and descends quickly, so as to quickly move to the specified position within a certain range. Preferably, the first range can be determined according to the relative positions of the components of the device, and it is judged whether the electric rotating gripper moves beyond this first range. If it exceeds, the moving direction is adjusted. Within the first range, the moving direction is not adjusted. Further, the real-time moving speed is inversely proportional to the moving time of the electric rotating gripper. The closer it is to the material frame, the higher the control accuracy is required. On the one hand, it avoids a large impact force causing the two to collide, and on the other hand, it avoids the electric rotating gripper shaking due to too high a speed, thereby reducing the accuracy of grasping.

[0202] It should be noted that the above steps describe the implementation process of installing the process plunger at the liquid injection port of the power lithium battery. When the liquid injection is completed, the process plunger needs to be pulled out. The following describes the implementation process of pulling out the process plunger from the liquid injection port of the power lithium battery.

[0203] During specific implementation, the plug module 7 continuously detects whether the process plunger at the liquid injection port of the power lithium battery needs to be pulled out. When it detects a process plunger that needs to be pulled out, the plug module 7 enters the working mode of pulling out the process plunger. The lifting and positioning conveyor module 6 moves the material frame to the position to be operated on, and lifts and positions the material frame to ensure accurate positioning of the material frame for subsequent pulling out operations. The plug module 7 accurately positions to the position where the process plunger is located based on the position of the material frame determined by the lifting and positioning conveyor module 6. The plug module 7 grasps the process plunger based on the position where the process plunger is located and pulls out the process plunger from the liquid injection port of the power lithium battery through reverse movement. During the pulling out process, the manipulator of the plug module 7 remains stable to prevent damage to the battery or the process plunger due to unstable pulling out operations. Further, the pulled out process plunger is conveyed to the designated receiving module 4 or separation module 3 for subsequent processing or recycling. After receiving the pulled out process plunger, the receiving module 4 or separation module 3 places it at the designated position and waits for further processing. After pulling out the process plunger, the screwing equipment checks the pulled out process plunger and the liquid injection port of the power lithium battery to confirm that the process plunger has been successfully pulled out and there is no remaining part in the liquid injection port of the power lithium battery.
