Abstract
Description
Technical Field
[0001] This invention relates to the field of battery technology, and in particular to a battery formation restraint machine. Background Technology
[0002] With the booming development of new energy vehicles and the increasing demands on their range, safety, and charging speed, the requirements for batteries are also rising. During the battery formation process, a large amount of gas is generated. If this gas is not discharged in time, it can easily cause the battery casing to expand, affecting the battery's appearance and performance. To limit battery casing expansion, battery formation restraint machines are generally used, especially in formation and settling processes, where these machines are essential to control battery expansion.
[0003] However, currently, battery restraint and release are mostly performed manually. Manual restraint is inefficient and affects the overall battery processing time. Furthermore, prolonged restraint and release work can easily lead to worker fatigue, and any omission in the operation can affect battery quality and even create safety hazards. Therefore, there is a need for an automated battery restraint and release mechanism to address these quality and safety concerns. Summary of the Invention
[0004] The main objective of this invention is to propose a battery formation restraint machine, which aims to automate the restraint and release of blade batteries. This machine has a high degree of automation, significantly improves production efficiency, and reduces the occurrence of safety issues.
[0005] To achieve the above objectives, the present invention provides a battery formation restraint machine, comprising: The formation restraint tray includes a fixed plate, a front push plate, a rear side plate, two guide rods, and multiple restraint plates. The two guide rods are connected between the fixed plate and the rear side plate. The front push plate is movably connected to the two guide rods and located between the fixed plate and the rear side plate. The two sides of the restraint plates are slidably sleeved on the two guide rods. The fixed plate is equipped with a rotating screw. The space between two adjacent restraint plates is used to place blade batteries. The decompression mechanism includes a mounting bracket, a rotating support plate, a nitrogen spring, a rotary drive module, a collet head, a linear drive module, and a push shaft. The linear drive module is mounted on the mounting bracket. The push shaft movably passes through the rotating support plate. The nitrogen spring is disposed between the rotating support plate and the mounting bracket. The linear drive module drives the push shaft to move linearly, passing through the fixed plate and pushing the push plate. When the collet head covers and presses against the rotating screw, the nitrogen spring provides elastic cushioning. The rotary drive module drives the collet head to rotate, causing the rotating screw to rotate.
[0006] Preferably, the linear drive module includes a servo motor, a first reducer, a ball screw, a first linear guide rail, a screw nut seat, a screw support seat, and a nut connector seat. The first linear guide rail is mounted on the mounting bracket, and the nut connector seat is slidably connected to the first linear guide rail. The servo motor drives and connects to the first reducer, which in turn drives and connects to the ball screw. The ball screw is threadedly connected to the screw nut seat, and the end of the ball screw away from the screw nut seat is connected to the screw support seat. The screw nut seat is connected to the nut connector seat. A linear bearing is provided on the rotating support plate, and one end of the push shaft is connected to the nut connector seat, while the other end is connected to the linear bearing. The rotary drive module is mounted on the rotary support plate and drives and connects to the ferrule head.
[0007] Preferably, the rotary drive module includes a rotary motor and a second reducer, the rotary motor being driven by the second reducer and the second reducer being driven by the ferrule head.
[0008] Preferably, the sleeve head is provided with a plurality of annularly arranged lugs, the rotating screw is provided with a protrusion, and a slot for accommodating the protrusion is formed between each pair of adjacent lugs.
[0009] Preferably, the linear drive module further includes an adapter plate and a pressure sensor. The adapter plate is connected to the nut seat, the pressure sensor is connected to the adapter plate, and the pressure sensor is connected to the nut connector. The pressure sensor is clamped between the adapter plate and the nut connector to detect the pressure value.
[0010] Preferably, the battery formation restraint machine further includes a pull-back mechanism, which includes a pull-back drive module and a pull-back plate. A pull-back rod is fixedly connected to the front push plate, and the pull-back rod passes through the fixed plate. The pull-back plate has several hook holes. The pull-back drive module is mounted on the mounting bracket. The pull-back drive module drives the pull-back plate, so that the pull-back plate hooks the pull-back rod through the hook holes and pulls it back.
[0011] Preferably, the hook hole is U-shaped.
[0012] Preferably, the pullback drive module includes a pullback connecting plate, a first cylinder, and two second cylinders. The first cylinder is used to drive the pullback connecting plate to move back and forth, and the two second cylinders are both mounted on the pullback connecting plate and are used to drive the pullback plate to move up and down.
[0013] Preferably, a second linear guide is mounted on the pullback connecting plate, and the pullback connecting plate is slidably connected to the second linear guide.
[0014] Preferably, the blade battery is placed vertically between two adjacent restraint plates.
[0015] Compared with the prior art, when the blade battery needs to be restrained, the present invention uses a linear drive module to drive the front push shaft forward, allowing it to pass through the through hole of the fixed plate and push the front push plate. The movement of the front push shaft against the front push plate gradually reduces the gap between the restraining plates, compressing the blade battery. During the process of the front push shaft pushing the front push plate, the rotating screw abuts against the clamping head and creates a reaction force. The clamping head transmits the force to the nitrogen spring through the rotating support plate. The nitrogen spring is compressed and buffered. At this time, the front push shaft stops at the corresponding position according to the preset pressure value. The rotation drive module drives the clamping head to rotate, causing the rotating screw to rotate and move forward, gradually pressing against the front push plate. This achieves the clamping of the blade battery between the restraining plates. Subsequently, the front push shaft, the rotating pullback connecting plate, and the clamping head retract, while the rotating screw continues to press against the front push plate, completing the restraint of the blade battery. When it is necessary to release the blade battery, the clamping head first fits onto and presses against the rotating screw. The rotary drive module drives the clamping head to reverse, causing the rotating screw to reverse as well. Simultaneously, the clamping head is subjected to the reaction force of the rotating support plate, causing the rotating support plate to retract. The elastic force of the nitrogen spring gradually decreases, and the movement stops after reaching the appropriate position. At this point, the linear drive module drives the front push shaft to retract, releasing the pressure on the front push plate and causing the various restraint plates to move to complete the release. With this configuration, the battery formation restraint machine of the present invention can realize the automated operation of restraining and releasing blade batteries, with a high degree of automation, significantly improving production efficiency and reducing the occurrence of safety production problems.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1 to 8 This invention proposes a battery formation restraint machine.
[0020] The battery formation restraint machine includes a formation restraint tray 100 and a decompression mechanism 200. The formation restraint tray 100 includes a fixed plate 110, a front push plate 120, a rear side plate 130, two guide rods 140, and multiple restraint plates 150. The two guide rods 140 are connected between the fixed plate 110 and the rear side plate 130. The front push plate 120 is movably connected to the two guide rods 140 and is located between the fixed plate 110 and the rear side plate 130. The restraint plates 150 are slidably sleeved on the two guide rods 140 on both sides. The fixed plate 110 is equipped with a rotating screw 160. The space between two adjacent restraint plates 150 is used to place the blade battery 101. The decompression mechanism 200 includes a mounting support. The system includes a frame 210, a rotating support plate 220, a nitrogen spring 230, a rotating drive module 240, a clamping head 250, a linear drive module, and a front push shaft 270. The linear drive module is mounted on the mounting bracket 210. The front push shaft 270 movably passes through the rotating support plate 220. A nitrogen spring 230 is provided between the rotating support plate 220 and the mounting bracket 210. The linear drive module is used to drive the front push shaft 270 to move linearly, so as to pass through the fixed plate 110 and push the front push plate 120. When the clamping head 250 covers and presses against the rotating screw 160, the nitrogen spring 230 provides elastic buffering. The rotating drive module 240 can drive the clamping head 250 to rotate, thereby driving the rotating screw 160 to rotate.
[0021] Specifically, the fixed plate 110 has a through hole 111, through which the front push shaft 270 passes and pushes against the front push plate 120. The front push plate 120 can move in the direction of squeezing the blade battery 101 under the pushing force of the front push shaft 270. Multiple sets of decompression mechanisms 200 can be set according to the restraint requirements to ensure the restraint effect on the blade battery 101. When it is necessary to restrain the blade battery 101, the linear drive module outputs a drive to move the front push shaft 270 forward, allowing the front push shaft 270 to pass through the through hole 111 of the fixing plate 110 and push the front push plate 120. The movement of the front push shaft 270 pushing the front push plate 120 gradually reduces the spacing between the restraint plates 150, compressing the blade battery 101. During the process of the front push shaft 270 pushing the front push plate 120, the rotating screw 160 abuts against the clamping head 250 and exerts a reaction force on it. The clamping head 250 transmits the force to the nitrogen bomb through the rotating support plate 220. When the nitrogen spring 230 is compressed and buffered, the front push shaft 270 stops at the corresponding position according to the preset pressure value. The rotation drive module 240 drives the clamping head 250 to rotate, which drives the rotating screw 160 to rotate and move forward to gradually press against the front push plate 120, thereby causing the restraint plates 150 to clamp the blade battery 101. Then, each front push shaft 270, the rotating pull-back connecting plate 313, and the clamping head 250 retract, and the rotating screw 160 continues to press against the front push plate 120, thus completing the restraint of the blade battery 101. When it is necessary to untie the blade battery 101, the clamping head 250 first fits onto and presses against the rotating screw 160. The rotary drive module 240 drives the clamping head 250 to reverse, causing the rotating screw 160 to reverse as well. At the same time, the clamping head 250 is subjected to the reaction force of the rotating support plate 220, causing the rotating support plate 220 to retract. The elastic force of the nitrogen spring 230 gradually decreases, and the movement stops after reaching an appropriate position. At this time, the linear drive module drives the front push shaft 270 to retract, releasing the pressure on the front push plate 120, and causing each restraint plate 150 to move to complete the untie. With this configuration, the battery formation restraint machine of the present invention can realize the automated operation of restraining and untieing the blade battery 101, with a high degree of automation, significantly improving production efficiency and reducing the occurrence of safety production problems.
[0022] Please see Figures 5 to 6Preferably, the linear drive module includes a servo motor 261, a first reducer 262, a ball screw 263, a first linear guide rail 264, a screw nut seat 265, a screw support seat 266, and a nut connecting seat 267. The first linear guide rail 264 is mounted on a mounting bracket 210, and the nut connecting seat 267 is slidably connected to the first linear guide rail 264. The servo motor 261 drives the first reducer 262, and the first reducer 262 drives the ball screw 263. The ball screw 263 is threadedly connected to the nut seat 265. A screw support seat 266 is connected to the end of the ball screw 263 away from the nut seat 265. The nut seat 265 is connected to the nut connecting seat 267. A linear bearing 268 is mounted on the rotating support plate 220. One end of the push shaft 270 is connected to the nut connecting seat 267, and the other end is connected to the linear bearing 268. A rotary drive module 240 is mounted on the rotary support plate 220 and drives the connecting sleeve head 250. Specifically, the servo motor 261 drives the first reducer 262 and transmits kinetic energy to the ball screw 263. The rotation of the ball screw 263 causes the threaded nut seat 265 to move. The nut seat 265 drives the nut connecting seat 267 to move. The nut connecting seat 267 slides on the first linear guide 264, thereby moving the push shaft 270, which in turn pushes the push plate 120 to complete the restraint. The lead screw support seat 266 serves to support the ball screw 263.
[0023] Please see Figures 5 to 6 Preferably, the rotary drive module 240 includes a rotary motor 241 and a second reducer 242. The rotary motor 241 drives the second reducer 242, and the second reducer 242 drives the clamping head 250. Specifically, the rotary motor 241 drives the second reducer 242 to increase the torque, thereby driving the clamping head 250, so that the clamping head 250 drives the rotary screw 160 to rotate, completing the pressing of the rotary screw 160 against the front push plate 120.
[0024] Please see Figure 8 Preferably, the retaining head 250 is provided with a plurality of annularly arranged lugs 251, and the rotating screw 160 is provided with a protrusion 161. A groove 252 for accommodating the protrusion 161 is formed between each pair of adjacent lugs 251. Specifically, the protrusion 161 of the rotating screw 160 is sleeved by the groove 252 on the retaining head 250, so that the retaining head 250 can drive the rotating screw 160 to rotate. In this embodiment, the periphery of the lugs 251 is circular to facilitate the protrusion 161 being inserted into the groove 252.
[0025] Please see Figure 1 , Figure 2 as well as Figure 6Preferably, the linear drive module further includes an adapter plate 270 and a pressure sensor 280. The adapter plate 270 is connected to a nut seat 265, and the pressure sensor 280 is connected to the adapter plate 270 and a nut connector 267. The pressure sensor 280 is clamped between the adapter plate 270 and the nut connector 267 to detect pressure values. Specifically, the adapter plate 270 is provided with holes for mounting the nut seat 265 and the pressure sensor 280, serving as an intermediate medium for installation matching between the two. When the nut seat 265 moves, it can drive the adapter plate 270, the pressure sensor 280, and the nut connector 267 to move. In this way, the nut seat 265 transmits thrust through the adapter plate 270 to the pressure sensor 280, and the pressure sensor 280 can detect the thrust of the nut seat 265 and thus detect the pressure value applied to the blade battery 101 by the restraint plate 150.
[0026] Please see Figure 7 Preferably, the battery formation restraint machine further includes a pull-back mechanism, which includes a pull-back drive module 300 and a pull-back plate 320. A pull-back rod 170 is fixedly connected to the front push plate 120 and passes through the fixed plate 110. The pull-back plate 320 has several hook holes 321. The pull-back drive module 300 is mounted on the mounting bracket 210. The pull-back drive module 300 drives the pull-back plate 320 so that the pull-back plate 320 hooks the pull-back rod 170 through the hook holes 321 and pulls it back. When the blade battery 101 needs to be removed, the ferrule head 250 unscrews the rotating screw 160, the front push shaft 270 retracts, and the pull-back drive module 300 drives the pull-back plate 320 to move. This causes the hook hole 321 of the pull-back plate 320 to hook the pull-back rod 170 of the restraint tray 100. The pull-back drive module 300 then drives the pull-back plate 320 to retract, pulling the pull-back rod 170 back. The pull-back rod 170 then causes the front push plate 120 to retract, widening the gap between the restraint plates 150, allowing the blade battery 101 to be removed.
[0027] Please see Figure 7 Preferably, the hook hole 321 is U-shaped. In this way, by driving the pull-back rod 170 to move back and forth and up and down, the hook hole 321 can hook the rod cap of the pull-back rod 170, which is simple and easy to implement.
[0028] Please see Figure 7Preferably, the pullback drive module 300 includes a pullback connecting plate 313, a first cylinder 311 and two second cylinders 312. The first cylinder 311 is used to drive the pullback connecting plate 313 to move back and forth. The two second cylinders 312 are both mounted on the pullback connecting plate 313 and are used to drive the pullback plate 320 to move up and down. Thus, when the pullback rod 170 needs to be pulled back, the second cylinder 312 located above drives the corresponding pullback plate 320 to move upward. Then, the first cylinder 311 drives the pullback connecting plate 313 to push the second cylinder 312 and the pullback plate 320 forward to the appropriate position. Afterward, the second cylinder 312 drives the pullback plate 320 to move downward, so that the pullback plate 320 hooks the rod cap of the pullback rod 170. The first cylinder 311 operates to drive the pullback plate 320 to retract, thereby pulling the pullback rod 170 to move, which in turn drives the front push plate 120 to pull out, increasing the distance between the various restraint plates 150, thus enabling the blade to be electrically... Battery 101 is removed; similarly, the second cylinder 312 located below drives the corresponding pull-back plate 320 to move down, and then the first cylinder 311 drives the pull-back connecting plate 313 to push the second cylinder 312 and the pull-back plate 320 forward to the appropriate position. After that, the second cylinder 312 drives the pull-back plate 320 to move upward, so that the pull-back plate 320 hooks the rod cap of the pull-back rod 170. The first cylinder 311 operates to drive the pull-back plate 320 to retract, so that the pull-back plate 320 pulls the pull-back rod 170 to move, thereby driving the front push plate 120 to be pulled out, so that the gap between each restraint plate 150 becomes larger, and the blade battery 101 can be removed.
[0029] Please see Figure 7 Preferably, a second linear guide rail 314 is mounted on the pull-back connecting plate 313, and the pull-back connecting plate 313 is slidably connected to the second linear guide rail 314. This ensures the smooth movement of the pull-back connecting plate 313 and facilitates the pull-back plate 320 to pull the pull-back rod 170 back.
[0030] Please see Figure 1 and Figure 4 Preferably, the blade battery 101 is placed vertically between two adjacent restraint plates 150. The formation restraint tray 100 is a vertical tray, and the blade battery 101 is placed vertically between the restraint plates 150.
[0031] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention.
