Description

[Technical Field]

[0001] The present invention relates to the field of battery manufacturing, and more particularly to a regulating device for applying constant pressure and automatic thickness control to horizontal terminals used in the formation of batteries. [Background technology]

[0002] During the manufacturing process of lithium batteries, it is necessary to continuously charge and discharge the lithium batteries to adjust and test their performance. The charge and discharge process typically uses a crimping mechanism, which includes positive and negative pin plate assemblies that can be opened and closed facing each other. The positive and negative pin plate assemblies are horizontally and mirror-imagely installed. During charge and discharge, lithium batteries are placed in the storage space between the separators to form a row. Rows of probes are arranged on the upper frame, one on each side of the row of lithium batteries. When the pin plate assembly is closed, the probes contact the poles of the lithium batteries, allowing the lithium batteries to be charged and discharged.

[0003] To ensure stable and reliable charging and discharging of lithium batteries, attention must be paid to the stability of the contact between the battery pole and the probe, that is, the vertical projection positions of the probe and the lithium battery pole must be aligned. If the probe and the lithium battery pole are misaligned, the probe will not be able to make effective contact with the lithium battery pole, which will affect the charging and discharging of the lithium battery.

[0004] "At the same time, conventional battery capacity grading equipment has a restraint tray that cannot accommodate batteries with large material battery tolerances, and is unable to provide constant pressure for the batteries during operation. Furthermore, when the batteries expand during the capacity grading process, they cannot be positioned accordingly, which affects the displacement of the batteries and probes, thereby affecting the performance and appearance of the batteries. Conventional capacity grading equipment uses sprinkler fire extinguishing, which uses an automatically triggered sprinkler system to first extinguish the fire with gas and then with water. However, this type of fire extinguishing method cannot completely cool the heat inside the batteries, making them prone to secondary battery fires and posing a hidden safety hazard to the equipment and factory buildings."

[0005] Patent Document 1 discloses a submerged charging / discharging mechanism in which a battery tray is placed on a three-layered central frame, consisting of a top frame, a middle frame, and a bottom frame. A downward-facing probe used for charging / discharging is installed on the central frame, and a fire extinguishing cylinder is pushed to submerge the central frame in a water tank assembly, immersing the entire battery tray and central frame and blocking air, thereby achieving the goal of safe fire extinguishing. In actual operation, the probe, which is still in the charging / discharging process, is submerged in the water tank assembly, creating a hidden safety hazard and adding an unnecessary equipment replacement step, which is not conducive to reducing production costs. Furthermore, the conventional probe used in this invention has a moving cylinder, making it difficult to accurately align the battery poles on the battery tray. Therefore, outside personnel must frequently manually adjust the battery tray position, which can easily result in poor contact between the probe and the battery.

The probe member initial position holding device 213 includes an initial positioning plate 2130 slidably installed on the probe slide rail 212, and an initial position cylinder 2134 fixed on the frame of the pin plate assembly 214. The cylinder extension shaft 2132 of the initial position cylinder 2134 passes through an axial hole of a cylinder base 2133 on the initial position cylinder 2134, and a shoulder is provided at the end of the cylinder extension shaft 2132 to prevent the cylinder extension shaft 2132 from coming out of the cylinder base 2133.

[0010] More specifically, the battery tray 6 to which the probe 2001 is docked includes a rectangular tray bottom frame 603, a vertical front fixing plate 600 is provided at the front end of the tray bottom frame 603, and a vertical rear fixing plate 607 is provided at the rear end thereof, the front fixing plate 600 is parallel to the rear fixing plate 607 and is connected to it via a vertical liner guide shaft 608, and a number of tray liner plates 611 are provided on the liner guide shaft 608 via slots 609 so as to be slidable in the vertical direction, and working positions for clamping the batteries are left between adjacent tray liner plates 611, A pusher 604 is provided on the tray liner plate closest to the rear fixing plate, a trapezoidal nut 605 and a restraining hole 610 are provided on the rear fixing plate 607, a vertical screw 606 passes through the trapezoidal nut 605 and contacts the pusher 604, the screw 606 moves vertically by rotating within the trapezoidal nut 605, and can push the pusher 604.

[0012] More specifically, a displacement sensor 2004 is provided on the top surface of the probe slider 2006. When the battery swelling reaches the probe member 200, the probe member 200 moves to move the position sensor 2004, and the detection result is fed back to the host machine, and when the battery swelling value exceeds the maximum displacement threshold, the system issues an alarm.

[0013] More specifically, a temperature gauge 2002 facing the battery tray 6 is provided on the probe slider 2006, and the temperature gauge 2002 senses the temperature of the battery and transmits it to the host machine.

[0014] More specifically, in order to prevent a large misalignment between the front-end equally divided rod combined member and the tray head 602 of the battery tray 6, the rear-end equally divided rod combined member 2003 of the multiple probe members 200 is made slightly longer than the rear-end equally divided rod combined member 2003 of the other probe members 200, so that the rear-end equally divided rod combined member 2003 is first aligned with the battery pole 601, and then the front-end equally divided rod combined member 2003 is pushed forward to move it, thereby ensuring guiding compatibility.

[0015] More specifically, the equally divided rod combining member 2003 includes an equally divided rod fixing base 20033, which is connected to the probe member 200, and which has an equally divided rod stopper 20034 on the outside and is connected to a positioning locking block 20031 on the inside via an equally divided rod 20030, which positioning locking block 20031 has a V-shaped jaw that can dock with the tray head 602 of the battery tray 6, and which has an equally divided rod spring 20032 mounted on the equally divided rod 20030.

[0016] More specifically, the outer frame is provided with an electrical cabinet 73 including a programmable logic controller (PLC), an alarm lamp 75 is provided at the top of the outer frame, a horizontal slide rail 72 is provided at the top of the outer frame, a slidable touch screen 71 is provided on the horizontal slide rail 72, and the outer frame is provided with multiple emergency exits 74 at the same height.

[0017] In the present invention, before the battery tray is inserted, the distance between the feed member 400 and the lift table 408 is adjusted and reduced by the load cylinder 407, so that the feed pulley 4001, infrared temperature sensor 406, and tool power supply pin 403 on the feed member 400 pass through the through holes on the lift table 408 and are exposed on the upper surface of the lift table 408.

[0018] When loading begins, the battery tray 6 is inserted into the feed member 400 through the load roller 13 at the front end of the frame middle frame 19 via an external load mechanism. As the battery tray 6 is pushed in, it is transported backward by the feed pulley 4001 located on the top of the lift table 408, and its position is limited by the position limiting stopper 402. When the infrared temperature sensor 406 detects the arrival of the battery tray 6, the load cylinder 407 pushes the lift table 408 and feed member 400 apart. The feed pulley 4001, which passes through the lift table 408 and is in contact with the bottom of the battery tray 6, descends together with the feed member 400 and no longer contacts the battery tray 6. At this time, the battery tray 6 is placed completely flat on the lift table 408. The piston rod of the tray clamp cylinder 105 on the upper frame member 10 is then pushed out, clamping the battery tray 6 between the tray clamp cylinder 105 and the lift table 408. Thereafter, the pin plate movement cylinder 11 pushes the probe mechanism 2 to bring it into pressure contact with the battery pole 601 on the battery tray 6, thereby carrying out charging and discharging.

[0019] If the temperature of the battery tray 6 becomes too high during the battery charging / discharging process and a fire occurs, the infrared temperature sensor 406 detects the abnormal temperature and transmits a fire alarm signal to the host machine. The host machine then controls the submersion cylinder 401, which pushes the piston rod of the submersion cylinder 401, which is fixed to the frame inner rim, downward, pushing the lift table 408, battery tray 6, and feed member 400 together and submerging them into the water tank assembly 3, but the probe mechanism 2 and frame inner rim 19 remain in their original positions and do not submerge. Once the fire in the battery tray 6 has been extinguished by cutting off the air, an outside worker opens the valve at the rear end of the water tank assembly 3 and replaces the submerged members.

[0020] When the pin plate movement cylinder 11 pushes the probe mechanism 2 toward the battery tray 6, the probes 2001 of the probe mechanism 2 precisely track and align with the battery poles 601 of the battery tray 6 one by one. The pin plate movement cylinder 11 pushes the probe mechanism 2 to contact the battery poles 601 on the battery tray 6, aligning the guide block 201 with the tray head 602 at the forefront of the battery tray, and the equally divided rod combination member 2003 on the probe member is aligned with the other tray head 602 of the battery tray. At this time, the guide block 201 contacts the forefront tray head 602, and the probe member 200, pulled backward by the tension spring 203, slides forward along the probe slide rail 212. The initial position cylinder 2134 pulls the guide block 201 via the cylinder extension shaft 2132 and the initial positioning plate 2130, maintaining the guide block and the row of probe members in the initial position. The four longer equally divided rod combining members 2003 on the rear probe member 200 first come into contact with the tray head 602 of the battery tray 6, and push out the equally divided rod combining members 2003 of the other probe members to align with the other tray heads 602 one by one, thereby completing the precise alignment of the probes 2001 and the battery poles 601.

[0021] When the battery tray 6 is docked with the restraint device 500 during charging or discharging, the electric cylinder 501 divides the thrust force equally among the four restraint guide shafts 5001 through the connecting block 5003, and the four restraint guide shafts 5001 then distribute the force among the pushers 604. The pressure sensor 5004 monitors the pressure-receiving status of the battery in real time, and the electric cylinder 501 adjusts the pressure applied to the pushers 604, ensuring that the pressure remains stable even when the battery expands due to charging.

[0022] The technical effect of the present invention is that the lift table for submerging the battery tray in water to extinguish the fire is separated from the frame middle section, and when extinguishing a fire, only the battery tray, lift table, and feed member are submerged and replaced by outside workers, eliminating the need to submerge the charged / discharged probe or the entire frame middle section, improving the safety of the equipment and reducing the number of parts that need to be cleaned, thereby saving time and costs in equipment maintenance.

However, the probe mechanism 2 and frame middle frame 19 remain in their original positions and are not submerged, and once the fire in the battery tray 6 has been extinguished by blocking the air, an external worker opens the valve at the rear end of the water tank assembly 3 and replaces the submerged members.

[0033] In this process, the lift table 408 for submerging the battery tray in water to extinguish the fire is separated from the frame middle section 19, and when extinguishing the fire, only the battery tray 6, lift table 408 and feed member 400 are submerged and replaced by external workers, so there is no need to submerge the charged / discharged probe member 200 or the entire frame middle section 19, improving the safety of the equipment and reducing the number of parts that need to be cleaned. Example 2

[0034] In this embodiment, based on the adjusting equipment of the horizontal terminal in embodiment 1 that applies constant pressure and automatic thickness adjustment, the probe mechanism 2 is improved to automatically adjust and track thickness changes during the battery formation process.

One side of the pin plate assembly 214 is formed with a vertical operating surface that interacts with the battery tray 6. The end of the vertical operating surface that is closer to the mounting screw 606 attached to the battery tray 6 is defined as the front, the side of the pin plate assembly 214 that faces the battery tray 6 is defined as the inside, and the opposite side is defined as the outside. The bottom of the pin plate mounting base 211 is slidably mounted on a pin plate movement slide rail 210 that is horizontally mounted so that the vertical moving surface of the pin plate assembly 214 can easily approach or move away from the battery tray 6. The pin plate movement slide rail 210 is mounted on the top of the pin plate slide rail fixing plate 208, and the pin plate slide rail fixing plate 208 is connected to the frame middle frame 19. A vertical probe slide rail 212 is provided on the vertical operating surface of the pin plate assembly 214, and a probe member 200 is slidably installed on the probe slide rail 212.

The initial positioning plate 2130 is connected to the guide block 201. In the initial position, the initial position cylinder 2134 pulls the initial positioning plate 2130, thereby holding the probe member 200 in its position. When the initial position cylinder 2134 is activated, the cylinder extension shaft 2132 extends, releasing the initial positioning plate 2130 and the guide block 201.

[0038] A temperature gauge 2002 facing the battery tray 6 is provided on the probe slider 2006, and the temperature gauge 2002 detects the temperature of the battery and transmits it to a host machine.

[0041] The probe member 200 is docked with the tray head 602 via the guide block 201 and the equally divided rod combining member 2003, thereby adjusting the alignment of the battery pole 601 and the probe 2001 in real time and automatically adapting to batteries of various thicknesses, thereby ensuring stable and reliable electrical contact between the probe 2001 and the battery pole 601 and preventing the battery pole 601 and the probe 2001 from shifting due to expansion during the battery charge / discharge process, and ensuring high-quality performance of the battery charge / discharge process. Example 3

[0042] This embodiment is based on the second embodiment and adds a tray constant pressure mechanism 5 to the battery tray 6, thereby maintaining a stable pressure on the battery when the thickness of the battery changes during the charging and discharging process.

[0043] 2 and 14 to 16, in this embodiment, the battery tray 6 to which the probe 2001 is docked includes a rectangular tray bottom frame 603, a vertical front fixing plate 600 is provided at the front end of the tray bottom frame 603, and a vertical rear fixing plate 607 is provided at the rear end thereof, the front fixing plate 600 is parallel to the rear fixing plate 607 and is connected via a vertical liner guide shaft 608, and a number of tray liner plates 611 are provided on the liner guide shaft 608 via slots 609 so as to be slidable in the vertical direction, and working positions for clamping the batteries are left between adjacent tray liner plates 611, A pusher 604 is provided on the tray liner plate 611 closest to the rear fixing plate 607, a trapezoidal nut 605 and a restraining hole 610 are provided on the rear fixing plate 607, a vertical screw 606 passes through the trapezoidal nut 605 and contacts the pusher 604, the screw 606 moves vertically by rotating within the trapezoidal nut 605, and the pusher 604 can be pushed and moved, a tray head 602 capable of docking with the equally divided rod combining member 2003 in the horizontal direction is provided at the top of the slot 609, and battery poles 601 are provided at both ends of the battery in the horizontal direction, A tray constant pressure mechanism 5 is connected to the front end of the battery tray 6, and the role of the tray constant pressure mechanism 5 is to use constant pressure to compress the batteries sandwiched between tray liner plates 611, thereby ensuring stability during the charging and discharging process. The tray constant pressure mechanism 5 includes a restraint device 500, which in turn includes a restraint guide shaft 5001, the front end of which is connected to a pusher 604, and the rear end of which is connected to a slider fixing plate 502 via a reinforcing plate 5002, a pressure sensor 5004, and a connection block 5003, in that order. The slider fixing plate 502 is connected to an electric cylinder 501, which is connected to an external mechanism, and the slider fixing plate 502 is connected to the frame inner frame 19 via an electric cylinder fixing plate 503.

[0044] In order to prevent a large misalignment between the front-end equally divided rod combined member 2003 and the tray head 602 of the battery tray 6, the rear-end equally divided rod combined member 2003 of the multiple probe members 200 is made slightly longer than the rear-end equally divided rod combined member 2003 of the other probe members 200. This allows the rear-end equally divided rod combined member 2003 to be first aligned with the battery pole 601, and then the front equally divided rod combined member 2003 to be pushed forward and moved, thereby ensuring guiding compatibility.

[0045] When the battery tray 6 is docked with the restraint device 500 during charging or discharging, the electric cylinder 501 divides the thrust force equally among the four restraint guide shafts 5001 through the connecting block 5003, and the four restraint guide shafts 5001 then distribute the force among the pushers 604. The pressure sensor 5004 monitors the pressure-receiving status of the battery in real time, and the electric cylinder 501 adjusts the pressure applied to the pushers 604, ensuring that the pressure remains stable even when the battery expands due to charging.

[0046] By combining the battery tray 6 and the restraining guide shaft 5001, the probe 2001 can follow the expansion of the battery in a restrained state, and the restraining guide shaft 5001 adjusts the battery pressure in real time through feedback from the pressure sensor 5004, preventing the battery from being damaged by expansion of its thickness during the charging and discharging process, affecting the battery's charging and discharging performance, and preventing indentations from appearing on the battery's exterior.

[0047] As mentioned above, although embodiments of the present invention have been shown and described, the above embodiments are illustrative and should not be understood as limitations on the present invention, and those skilled in the art may make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
