Description

[Technical Field]

[0001] The present invention relates to the field of battery manufacturing, and more particularly to an automatic adjustment device for lateral terminals used in the formation of batteries to accommodate batteries of different thicknesses and expansion and contraction. [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. Probes are arranged in a row on the upper frame, with the probe rows located on the left and right sides of the lithium battery row. 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-layer frame inner section, which has a top, middle, and bottom frame. A downward-facing probe used for charging / discharging is installed on the frame inner section. A fire extinguishing cylinder is pushed to submerge the frame inner section into a water tank assembly, immersing the entire battery tray and frame inner section 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 often manually adjust the battery tray position, which can easily lead to poor contact between the probe and the battery. [Prior art documents] [Patent documents]

A probe member initial position holding device 213 and a guide block 201 are provided in front of the probe slide rail 212. A number of tray liner plates 611 for holding batteries are arranged front and rear inside the external battery tray 6. The tray liner plates 611 can slide back and forth inside the battery tray 6.

[0010] More specifically, a vertical drawer pin plate slide rail 202 is provided on the pin plate mounting base 211, and a pin plate pull tab 204 is provided at the front end of the pin plate assembly 214. The pin plate assembly 214 is slidably installed on the drawer pin plate slide rail 202 and can be removed from the drawer pin plate slide rail 202.

[0011] 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 displacement sensor 2004 is moved by the movement of the probe member 200, 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.

[0012] 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.

[0013] 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 post 601, and then the front-end equally divided rod combined member 2003 is pushed forward to move it, thereby ensuring guiding compatibility.

[0014] 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.

[0015] More specifically, the temperature collection module 205 is mounted at the front end of the pin plate assembly 214 .

[0016] More specifically, a current connector 206 and an adapter plate 207 for connecting an external circuit are provided on the top of the pin plate assembly 214 .

[0017] More specifically, the water tank assembly 3 includes a water tank body 301, the side of which is provided with a water intake 302 and an overflow port 303 to prevent the water level from rising too high, and the bottom is provided with a water outlet 304 for drainage. The valve structure at the front of the water tank body 301 can be opened to facilitate removal of submerged equipment for cleaning and replacement.

[0018] In the present invention, before the battery tray 6 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 hole 409 on the lift table 408 and are exposed on the upper surface of the lift table 408.

[0019] 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 is no longer in contact with the battery tray 6. At this point, 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 moving cylinder 11 pushes the probe mechanism 2 to bring it into pressure contact with the poles of the battery on the battery tray 6, thereby carrying out charging and discharging.

[0020] 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 frame 19, downward, pushing the lift table 408, battery tray 6, and feed member 400 together and submerging them into the water tank assembly 3. The probe mechanism 2 and frame inner frame 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.

[0021] 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, and aligns the guide block 201 with the tray head 602 at the forefront of the battery tray, so that 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, and the initial position cylinder 2134 pulls the guide block 201 via the cylinder extension shaft 2132 and the initial positioning plate 2130, thereby holding the guide block and the row of probe members in their initial positions. 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.

[0022] The technical effects of the present invention are 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 external workers, eliminating the need to submerge the charging / discharging probe or the entire frame middle section, improving equipment safety and reducing the number of parts that need to be cleaned, thereby saving equipment maintenance time and costs; and that by establishing one-to-one tracking positioning between the probe and the battery, the probe is always aligned with the battery electrode, ensuring effective contact with the electrode, even if expansion or contraction occurs during the battery charging / discharging process or if there is an error in the battery thickness, thereby ensuring the quality of the battery charging / discharging operation.

The bottom is provided with a water discharge port 304 for draining water. A valve at the front of the water tank body 301 can be opened to facilitate removal of submerged equipment for cleaning and replacement. 9 and 10, a lifting and transporting mechanism 4 connected to the frame bottom frame 17 is provided in the center of the frame middle frame 19. The lifting and transporting mechanism 4 moves up and down independently of the frame middle frame 19, and can serve to lift and transport the battery tray 6. A vertical guide column 404 is connected to the frame bottom frame 17 via a movement axis fixing welded plate 16 and a guide column fixing member 405 in this order. The guide column 404 passes through the water tank assembly 3, and the upper part of the guide column 404 A horizontal feed member 400 is provided on the top of the feed member 400, and two rows of feed pulleys 4001 arranged vertically, an infrared temperature sensor 406, and a tool power attachment pin 403 are provided on the top of the feed member 400. A lift table 408 is mounted on the top of the feed member 400, and the feed pulleys 4001, the infrared temperature sensor 406, and the tool power attachment pin 403 pass through through holes 409 on the lift table 408, and a space between the feed member 400 and the lift table 408 is provided. a load cylinder 407 is provided on the top of the lift table 408, one battery tray 6 is placed on the top of the lift table 408, the battery tray 6 is located between the two probe mechanisms 2 and is located at the same height as the probe mechanisms 2, a position limiting stopper 402 for the battery tray 6 is provided at the rear end of the upper surface of the lift table 408, a piston rod of a submerged cylinder 401 is connected to the lift table 408, the submerged cylinder 401 is connected to the frame middle frame 19, the feed member 400 and lift table 408 are slidably installed on guide columns 404, a tray damping block 4002 is provided on the top of the feed member 400 to limit the left and right position of the battery tray 6 when the battery tray 6 is carried in from the load rollers 13, and a buffer block 4003 is further provided on the top of the feed member to prevent a violent collision when the feed member 400 approaches the lift table 408, In the specific operation process, the battery tray 6 is carried into the load member from the load roller 13 at the front end of the frame middle section 19 through an external load mechanism. When the battery tray 6 is pushed in, it is transported backward by the feed pulley 4001 located at 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 installed between the lift table 408 and the feed member 400 is pushed out, separating the lift table 408 and the feed member 400, penetrating the lift table 408 and making contact with the bottom of the battery tray 6.
