Description

Technical Field

[0002] In the field of new energy lithium battery technology, the formation and capacity separation process of square shell lithium battery is a key link in the battery production process. The formation process is to activate the chemically active substances in the positive and negative electrodes of the battery to ensure that the battery has stable electrochemical reaction capabilities, while the capacity separation process is to classify the capacity of the activated battery to meet the needs of different application scenarios.

[0003] Traditional chemical capacity separation equipment usually adopts a design that separates the bed-of-nails cabinet and the power cabinet. The two are connected by long cables to achieve signal and energy transmission and transfer. This design method not only leads to a large number of cables and excessive lengths, but also generates significant line losses during the charging and discharging process, greatly reducing energy efficiency. In addition, opening holes in the wall for wiring also increases the complexity and cost of equipment installation.

[0004] More importantly, the probe module structure of traditional chemical fractionation equipment is often fixed at both ends of the frame. During maintenance, multiple operators are required to be located in front and behind the equipment to work together to disassemble or adjust the probe module. During this process, the operator needs to hold the probe module to prevent it from falling. The operation is cumbersome and laborious, which not only increases maintenance costs, but also reduces the efficiency of equipment use.

[0047] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0048] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0049] In the field of new energy lithium batteries, the process of chemical composition of square shell lithium batteries is crucial. Traditional equipment is designed with a separate needle bed cabinet and power cabinet, and long cable connections lead to serious line losses, low energy efficiency, and complex installation costs. Secondly, the probe module is fixed at both ends of the equipment frame, and maintenance requires the collaboration of multiple people, which is cumbersome and affects the efficiency and flexibility of the equipment. In addition, traditional chemical composition equipment often lacks a flexible adjustment mechanism for batteries of different models and sizes.

[0050] To solve the above problems, please refer to Figures 1 to 11 The embodiment of the present invention provides a device for forming a capacity of an embedded square-shell lithium battery, comprising:

[0051] The support frame 10, as a stable foundation of the entire device, not only provides sufficient mechanical strength, but also ensures the stability and safety of the device during operation.

[0052] The top frame 20 is mounted on the support frame 10 , and a receiving cavity 30 is formed between the support frame 10 and the top frame 20 .

[0053] The lifting frame 40 is movably installed in the accommodating cavity 30 .

[0054] The driving component 50 is fixedly mounted on the top frame 20 , and is used to drive the lifting frame 40 to move up and down along the longitudinal direction of the accommodating cavity 30 .

[0055] The adjustable probe module 60 is slidably mounted on the top frame 20. When maintenance is required, the adjustable probe module 60 can be quickly pulled out, which is convenient for later maintenance and can be operated without the cooperation of multiple people, which not only reduces the configuration of maintenance personnel, but also reduces maintenance costs.

[0056] The circuit board component 70, multiple circuit board components 70 are embedded and installed in the adjustable probe module 60. The integrated design reduces the use of cables and makes the installation and maintenance of the adjustable probe module 60 easier, simplifies the overall structure, reduces the line loss in the charging and discharging process caused by the excessive length of the cable, and improves the energy utilization efficiency. In addition, the multiple circuit board components 70 are arranged in parallel and equidistantly, which ensures the stable transmission of signals and energy and improves the overall performance. The circuit board component 70 is also electrically connected to the adjustable probe module 60.

[0057] The cell tray 80 is arranged in the accommodating cavity 30 and is located between the lifting frame 40 and the top frame 20, and can be raised and lowered with the lifting frame 40. The cell tray 80 is provided with a cell module 81 corresponding to the adjustable probe module 60, and the adjustable probe module 60 is electrically abutted with the cell module 81 through the elastic probe member 61. Specifically, the driving component 50 drives the lifting frame 40 to perform lifting and lowering movements, thereby driving the cell tray 80 to lift and lower, thereby realizing the pressing and disengagement of the cell module 81 and the adjustable probe module 60, ensuring the efficiency and accuracy of the chemical separation operation. In addition, an adjustment limit column 41 is also provided on the side of the lifting frame 40 close to the top frame 20. The adjustment limit column 41 is used to limit the movable stroke of the lifting frame 40 to adjust the abutment compression amount between the elastic probe member 61 and the cell module 81, thereby meeting the needs of different chemical separation processes and improving the flexibility and adaptability of the equipment.

[0058] It should be noted that the flexibility and adjustability of the adjustable probe module 60 enable the device to adapt to battery modules 81 of different specifications and sizes, further improving the versatility of the device.

[0059] In this example, see Figure 1, the driving component 50 is installed on the side of the top frame 20 away from the support frame 10, and is arranged on both sides of the top frame 20 symmetrically. This design allows the driving components 50 on both sides to work synchronously and jointly drive the lifting frame 40 to rise and fall smoothly, thereby improving the accuracy and efficiency of the lifting movement and ensuring the stability and balance of the device during operation. In addition, the adjustable probe module 60 is arranged between the two driving components 50. Such a layout arrangement not only optimizes the spatial layout and makes the device structure more compact, but also enables the adjustable probe module 60 to be evenly stressed, avoiding deviation or damage caused by uneven force. At the same time, it is also convenient for precise alignment with the battery cell module 81 on the battery cell tray 80, ensuring the smooth progress of the chemical separation operation.

[0060] See also Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig.11 A plurality of guide rails 21 arranged in parallel are installed on the top frame 20, and the adjustable probe module 60 includes a module frame 62. Cam followers 621 are symmetrically arranged on both sides of the module frame 62. A guide groove 211 is opened on the guide rail 21. The module frame 62 is slidably installed on the guide groove 211 through the cam follower 621, that is, the adjustable probe module 60 can slide on the top frame 20 along the length direction of the guide groove 211 through the cam follower 621. When maintenance is required, it is convenient for the maintenance personnel to quickly pull out the adjustable probe module 60, which significantly shortens the maintenance and disassembly time and improves the utilization rate of the device. The end of the module frame 62 away from the top frame 20 is provided with a heat dissipation component 63, which can efficiently dissipate the heat generated by the circuit board component 70 during operation, ensuring the stability and life of the electronic components installed on the circuit board component 70. The other end of the module frame 62 is installed with an adjustable electrode component 64 to be compatible with the cell poles of the cell modules 81 of different specifications and sizes, thereby achieving wide compatibility and operational convenience of the device. The circuit board component 70 is installed in the module frame 62 and arranged between the heat dissipation component 63 and the adjustable electrode component 64. Such a layout not only ensures a good heat dissipation effect, but also further optimizes the spatial layout. The adjustable electrode component 64 is in contact with the cell module 81 through the elastic probe component 61, ensuring the pressed connection and disconnection between the cell module 81 and the adjustable probe module 60, thereby ensuring the stability of the capacity conversion operation. Please refer to Figure 4The first mounting support plates 11 are symmetrically installed on both sides of the support frame 10. Support columns 12 are provided at both ends of the first mounting support plates 11. One end of the support column 12 is connected to the support frame 10, and the other end is connected to the top frame 20, which ensures the stability of the structural connection and further improves the bearing capacity and stability of the device. The first mounting support plate 11 is installed with a guide column 13, which is symmetrically arranged at both ends of the first mounting support plate 11. The lifting frame 40 is sleeved and installed on the guide column 13 and can reciprocate along the length direction of the guide column 13. The design of the guide column 13 provides guiding support for the precise movement of the lifting frame 40, ensuring the stability and accuracy during the lifting process. A tray support column 14 is provided on the side where the two first mounting support plates 11 are close to each other. One end of the tray support column 14 passes through the lifting frame 40 and is installed with a tray guide seat 15. The battery tray 80 is placed on the tray guide seat 15. Here, the tray guide seat 15 provides stable support and precise guidance for the placement of the battery tray 80, ensuring the stability and safety of the battery tray 80 during the chemical separation operation. A tray feeding station 90 is provided on one side of the accommodating chamber 30 to facilitate the rapid loading of the battery tray 80. A tray anti-dumb pin 16 is installed in the middle of the side of the support frame 10 away from the tray feeding station 90. The tray anti-dumb pin 16 is used to detect whether the incoming battery tray 80 is placed in place, effectively avoiding errors and device failures caused by improper placement, and improving the accuracy of the operation and the reliability of the device. Figure 5 A second mounting support plate 42 is symmetrically provided on both sides of the lifting frame 40, a joint fixing block 43 is installed in the middle of the second mounting support plate 42, and the action end of the driving component 50 is fixedly connected to the joint fixing block 43, ensuring the effective transmission of the driving force and the precise execution of the lifting action. The adjusting limit column 41 is arranged on both sides of the joint fixing block 43. Through a reasonable layout, the stability of the stroke limit of the lifting frame 40 and the safety of the operation of the device are ensured, avoiding the interference of structural components due to uneven force on the lifting limit, thereby causing blocking.

[0061] It should also be noted that, in a preferred embodiment, the driving component 50 is a driving cylinder, and the transmission end of the driving component 50 is connected to the joint fixing block 43 via a cylinder connector.

[0062] For further information, see Figure 7 , Figure 8 , Fig.10 ,and Fig.11The adjustable electrode assembly 64 includes a positive probe component 641 and a negative probe component 642. The positive probe component 641 and the negative probe component 642 can be adjustably installed at one end of the module frame 62 close to the battery module 81. The adjustable installation design ensures that no matter how the specifications of the battery module 81 change, the positive probe component 641 and the negative probe component 642 can be accurately adapted to achieve stable contact with the positive and negative ends of the battery module 81. The positive probe component 641 and the negative probe component 642 are respectively contacted with the positive and negative ends of the battery module 81 through the elastic probe component 61. A negative pressure manifold 65 is also provided on the side of the heat dissipation assembly 63. The negative pressure manifold 65 Installed on the module frame 62, a negative pressure cup 651 is also provided between the negative pressure manifold 65 and the heat dissipation component 63, the negative pressure cup 651 is installed on the module frame 62, and a suction nozzle component 66 is also provided between the positive probe component 641 and the negative probe component 642. The suction nozzle component 66 is adjustably installed at one end of the module frame 62 away from the heat dissipation component 63 to adapt to different specified battery modules 81. One end of the negative pressure cup 651 is connected to the negative pressure manifold 65 through the first negative pressure hose 652, and the other end is connected to the suction nozzle component 66 through the second negative pressure hose 653, forming an efficient negative pressure circulation system, which provides a strong guarantee for the efficient and accurate lithium battery charging process.

[0063] A temperature probe component 67 is also installed on the side of the negative probe component 642 close to the suction nozzle component 66 to monitor the temperature changes in the negative electrode area in real time and accurately, and provide key data support for the thermal management of the battery cell module 81, thereby ensuring the safety of the capacity conversion process. The positive probe component 641, the negative probe component 642 and the suction nozzle component 66 are arranged in parallel. This layout not only ensures the independence and non-interference of each component during the test, but also improves the overall aesthetics and compactness of the equipment, and facilitates operation and maintenance. Scale indicator plates 68 are provided at both ends of the positive probe component 641, the negative probe component 642 and the suction nozzle component 66, and a scale ruler 69 corresponding to the scale indicator plate 68 is also installed on the module frame 62. This detailed design allows the operator to intuitively and quickly adjust the position of each component to achieve precise positioning.

[0064] Among them, the length dimension of the cam follower 621 is smaller than the depth dimension of the guide groove 211, which ensures that the cam follower 621 can slide freely and stably in the guide groove 211, reduces the friction and resistance caused by size mismatch, and improves the smoothness and durability of the operation of the device. The module frame 62 is also symmetrically provided with guide limit blocks 622 that are compatible with the guide groove 211 on both sides, and the guide limit blocks 622 are slidably installed on the guide groove 211. These guide limit blocks 622 not only provide precise guidance for the sliding of the module frame 62 on the guide groove 211, but also effectively prevent the module frame 62 from deflecting and shaking during the sliding process through its structural limiting effect, thereby ensuring the stability and safety of the device operation.

[0065] See also Figure 1 , Figure 2 , Figure 6 and Fig.10 A limiting cross plate 212 is fixedly installed at one end of the guide rail 21 away from the tray feeding station 90, which plays an effective limiting role to prevent the module frame 62 from exceeding a predetermined range during the sliding process. A limiting protrusion 213 is removably installed at the other end of the guide rail 21. The limiting protrusion 213 is used to limit the installation position of the module frame 62 to ensure that the module frame 62 has a stable position after being installed in place. A handle 623 is also installed at one end of the module frame 62 close to the tray feeding station 90, which is convenient for operators to disassemble and maintain the module frame 62 and improve work efficiency.

[0066] The second mounting support plate 42 is also symmetrically provided with linear bearing sleeves 44 adapted to the guide column 13, ensuring the smooth sliding of the guide column 13 in the linear bearing sleeves 44, reducing friction and vibration, and improving the running accuracy and stability of the device. The adjustment limit column 41 is installed on the second mounting support plate 42 and is arranged between the linear bearing sleeves 44 and the joint fixing block 43, ensuring the relative position between the components is accurate, thereby ensuring the running effect of the overall device. Figure 4A first stroke detection switch 141 is provided at one end of the support frame 10 close to the tray anti-stupid pin 16 and at the other end of the support frame 10 away from the tray anti-stupid pin 16. The two first stroke detection switches 141 are respectively located on the symmetrical sides of the battery tray 80 and are installed on the tray support column 14. The first stroke detection switch 141 is used to detect whether the battery tray 80 is accurately placed in the accommodating cavity 30, providing reliable signal feedback for the automated process and ensuring the smooth progress of subsequent operations. A sensor sheet 46 is also provided on the side of any linear bearing sleeve 44. The sensor sheet 46 is installed on the lifting frame 40. An upper stroke sensor 121 and a lower stroke sensor 122 that are compatible with the sensor sheet 46 are also installed on the support column 12. This design realizes real-time monitoring of the lifting position of the lifting frame 40, ensures precise control of the lifting frame 40 during the lifting process, and prevents operational errors or device damage caused by position deviation. Please refer to Figure 5 The end of the lifting frame 40 away from the tray anti-stupid pin 16 and the end of the lifting frame 40 close to the tray anti-stupid pin 16 are both installed with a second stroke detection switch 45. The two second stroke detection switches 45 are arranged on both sides of the battery tray 80 symmetrically. The second stroke detection switch 45 is used to detect whether the battery tray 80 is accurately placed on the lifting frame 40 when the lifting frame 40 is lifted, which provides an important safety guarantee for automated operation and avoids equipment failure or production accidents caused by incorrect placement of the battery tray 80. A tooling power supply component 49 is provided on either side of the battery tray 80 close to the joint fixing block 43, and the tooling power supply component 49 is installed on the lifting frame 40. The design of the tooling power supply component 49 meets the stable supply demand of the device for electric energy and improves the operating efficiency and reliability of the overall device.

[0067] Furthermore, tray guide blocks 47 corresponding to the battery tray 80 are installed on both symmetrical sides of the lifting frame 40 near the support column 12, ensuring the stability and directionality of the battery tray 80 during the lifting process, preventing the battery tray 80 from shifting or shaking during the rising process, and laying the foundation for subsequent precise operations. The tray guide block 47 is provided with a fitting groove 471 on one side near the joint fixing block 43, and its shape matches the edge of the battery tray 80, providing precise guidance and positioning functions for the battery tray 80. When the battery tray 80 contacts the fitting groove 471, it can be quickly and accurately positioned to the predetermined position, thereby improving the operating accuracy of the device. A guide slope 472 is provided at one end of the fitting groove 471 away from the lifting frame 40, which utilizes the principle of inclined surface guidance, so that the battery tray 80 can slide smoothly and steadily into the fitting groove 471 during the rising process, reducing the difficulty of alignment and improving the operating efficiency of the equipment. Tray positioning pins 48 corresponding to the tray guide blocks 47 are also installed on the side of the lifting frame 40 close to the battery tray 80. After the battery tray 80 completely slides into the fitting groove 471, these tray positioning pins 48 can further fix the position of the battery tray 80 to ensure that it has a stable position during the lifting process. This design ensures the precise docking between the battery module 81 in the battery tray 80 and the adjustable probe module 60, thereby achieving accurate pressing of the battery module 81 and the adjustable probe module 60, and improving the production quality and consistency of the product.

[0068] See also Figure 6 , a smoke sensor 22 and a gas detector 23 are also provided on the top frame 20. The provision of these two sensors further enhances the safety protection level of the device. The smoke sensor 22 and the gas detector 23 are respectively installed at the symmetrical ends of one side of the top frame 20 close to the battery tray 80. This layout ensures that they can fully and accurately monitor the smoke and harmful gases that may be generated during the charging and discharging process, making it possible to promptly discover and deal with abnormal situations. Among them, the gas detector 23 is a CO detector, that is, a carbon monoxide detector. This is a special monitoring device set up for harmful gases such as carbon monoxide that may be generated during the charging and discharging process of the battery. It can ensure that an alarm is quickly sounded when the concentration of harmful gases exceeds the standard to prevent them from causing harm to the environment and personnel. Please refer to Figure 1 and Fig. 9, a fire sprinkler component 24 is also installed on the top frame 20. This design constitutes the last line of defense of the equipment's safety protection system. The addition of the fire sprinkler component 24 enables the emergency response mechanism to be quickly activated when an abnormal situation is detected, effectively reducing the risk of fire by spraying water and other means, and ensuring the safety of equipment and personnel. It should be noted that the setting of the smoke sensor 22 and the gas detector 23 is not only a monitoring means, but they also realize closed-loop control from monitoring to response through linkage with the fire sprinkler component 24. When an abnormal situation is detected, the system will immediately start the fire sprinkler component 24 and perform operations such as spraying water to extinguish the fire, thereby effectively avoiding the occurrence of extreme situations such as deflagration. The fire sprinkler component 24 is "U"-shaped, ensuring the wide range and uniformity of the water spray range. Specifically, the fire sprinkler component 24 includes a high-pressure fire branch pipe 241 and a high-pressure fire branch pipe 242. The high-pressure fire branch pipe 241 is installed on one side of the top frame 20 through a fire pipe fixing 243, providing stable support for the entire fire sprinkler system. The high-pressure fire branch pipe 242 is symmetrically arranged on both sides of the high-pressure fire branch pipe 241 and is located between the driving component 50 and the adjustable probe module 60. This layout not only ensures the comprehensive coverage of the battery tray 80 and its surrounding areas by the fire sprinkler system, but also avoids mutual interference with other components of the device. The high-pressure fire branch pipe 242 is connected to the high-pressure fire branch pipe 241. A plurality of water outlet branch pipes 244 arranged at equal intervals are also installed on the high-pressure fire branch pipe 242. The water outlet branch pipes 244 pass through the top frame 20 and extend into the accommodating cavity 30. Fire sprinkler heads 245 are installed at the water outlet ends of the plurality of water outlet branch pipes 244. This design enables the fire sprinkler heads 245 to be accurately positioned on the battery cell tray 80 and its surrounding areas, thereby achieving precise strikes on potential fire sources and further ensuring the safety of the charging and discharging process.
