[0002] Polymer power batteries, as a new generation of power and energy storage sources, boast superior performance, reliable manufacturing processes, and wide applications. The production process of polymer power batteries involves steps such as loading and unloading. During automated loading and unloading, collisions can cause minor issues like battery surface defects or, in severe cases, lead to fires. Therefore, preventing collisions during loading and unloading is crucial. Currently, the transfer process for polymer power batteries lacks the ability to provide early warnings for potential hazards during loading and unloading. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a polymer power battery anti-collision robotic arm capable of providing early warning of potential dangerous accidents during battery loading and unloading.

[0006] The robotic arm mounting mechanism includes a collision-resistant mounting plate and a spacing adjustment mechanism mounted on the collision-resistant mounting plate. The collision-resistant mounting plate is a horizontal rectangular plate. The extension direction of one side of the collision-resistant mounting plate is defined as longitudinal, and the extension direction of the other side of the collision-resistant mounting plate is defined as transverse. The spacing adjustment mechanism includes a longitudinal drive unit and a bidirectional lead screw. The longitudinal drive unit is mounted on the collision-resistant mounting plate, and the power output end of the longitudinal drive unit is connected to one end of the bidirectional lead screw. The longitudinal drive unit drives the bidirectional lead screw to rotate circumferentially around its own longitudinal central axis. The bidirectional lead screw is provided with two ball nuts. When the bidirectional lead screw rotates, the two ball nuts move in opposite directions on the bidirectional lead screw, and a nut slider is installed on each ball nut.

[0007] Two sets of battery gripping mechanisms are symmetrically arranged below the anti-collision mounting plate. The battery gripping mechanism includes a pneumatic gripper mounting plate, which is installed on the bottom of the nut slider. A row of gripping manipulators is installed horizontally on the bottom of the pneumatic gripper mounting plate. The gripping manipulators on the two pneumatic gripper mounting plates correspond one-to-one and are arranged in a row vertically. The gripping manipulators in the same row grip both ends of the same polymer power battery.

[0008] The system includes an anti-collision mechanism located on the upper part of the anti-collision mounting plate, comprising a connecting plate, an anti-collision buffer rod assembly, and a pressure sensor. The connecting plate is located at the top of the anti-collision mounting plate. The anti-collision buffer rod assembly is vertically inserted into the connecting plate, and its bottom end is connected to the anti-collision mounting plate. The pressure sensor is located between the connecting plate and the anti-collision mounting plate, and its bottom is fixedly connected to the anti-collision mounting plate.

[0011] Furthermore, the bottom of the anti-collision mounting plate is provided with a guide rail pad block, which is long and thin. The bottom of the guide rail pad block is equipped with a longitudinal guide rail, and two longitudinal sliders are slidably mounted on the longitudinal guide rail. The longitudinal sliders correspond one-to-one with the nut sliders and are aligned in the horizontal direction. The longitudinal sliders and the nut sliders aligned in the horizontal direction are respectively connected to the two ends of the pneumatic gripper mounting plate in the horizontal direction.

[0012] Furthermore, the gripping robot includes a gripper mounting plate, a clamping cylinder, and a gripper assembly.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0029] A polymer power battery loading and unloading anti-collision robotic arm includes:

[0030] The robotic arm mounting mechanism 400 includes a collision-resistant mounting plate 100 and a spacing adjustment mechanism 200 disposed on the collision-resistant mounting plate 100. The collision-resistant mounting plate 100 is a horizontal rectangular plate. The extension direction of one side of the collision-resistant mounting plate 100 is defined as longitudinal, and the extension direction of the other side of the collision-resistant mounting plate 100 is defined as transverse. The spacing adjustment mechanism 200 includes a longitudinal drive unit 201 and a bidirectional lead screw 202. The longitudinal drive unit 201 is disposed on the collision-resistant mounting plate 100, and the power output end of the longitudinal drive unit 201 is connected to one end of the bidirectional lead screw 202. The longitudinal drive unit 201 drives the bidirectional lead screw 202 to rotate circumferentially around its own longitudinal central axis. Two ball nuts 215 are provided on the bidirectional lead screw 202. When the bidirectional lead screw 202 rotates, the two ball nuts 215 move in opposite directions on the bidirectional lead screw 202. A nut slider 216 is correspondingly installed on each ball nut 215.

[0031] Two sets of battery gripping mechanisms 300 are symmetrically arranged below the anti-collision mounting plate 100. Each battery gripping mechanism 300 includes a pneumatic gripper mounting plate 301, which is mounted on the bottom of the nut slider 216. A row of gripping manipulators 302 is mounted horizontally on the bottom of the pneumatic gripper mounting plate 301. The gripping manipulators 302 on the two pneumatic gripper mounting plates 301 correspond one-to-one and are arranged in a row in the vertical direction. The gripping manipulators 302 in the same row grip both ends of the same polymer power battery.

[0032] The system includes an anti-collision mechanism 500, located on the upper part of the anti-collision mounting plate 100, comprising a connecting plate 501, an anti-collision buffer rod assembly 502, and a pressure sensor 503. The connecting plate 501 is located at the top of the anti-collision mounting plate 100. The anti-collision buffer rod assembly 502 is vertically inserted into the connecting plate 501, and its bottom end is connected to the anti-collision mounting plate 100. The pressure sensor 503 is located between the connecting plate 501 and the anti-collision mounting plate 100, and its bottom end is fixedly connected to the anti-collision mounting plate 100.

The second synchronous pulley 213 is mounted on the end of the bidirectional lead screw 202 near the motor 210. A synchronous belt 212 is arranged around the second synchronous pulley 213 and the first synchronous pulley 211. The synchronous belt 212 is in a tensioned state, realizing the power transmission between the motor 210 and the bidirectional lead screw 202. The motor 210 drives the two ball nuts 215 to move in opposite directions through the first synchronous pulley 211, the synchronous belt 212, the second synchronous pulley 213, and the bidirectional lead screw 202, thereby achieving the function of adjusting the longitudinal spacing of the two battery gripping mechanisms 300 to accommodate polymer power batteries of different sizes.

[0034] In some embodiments of the present invention, the two ends of the bidirectional lead screw 202 are rotatably mounted on the bottom of the anti-collision mounting plate 100 via two sets of moving platform bearing seats 214. The bidirectional lead screw 202 is provided with two external thread sections with opposite directions of rotation. Each of the two external thread sections of the bidirectional lead screw 202 is fitted with a ball nut 215. The external thread section is threadedly connected to the corresponding ball nut 215. The bidirectional lead screw 202 can rotate around its own longitudinal central axis under the drive of the motor 210, causing the ball nut 215 to move in the opposite direction. Since the nut slider 216 is fixed to the ball nut 215, the nut slider 216 can drive the corresponding pneumatic gripper mounting plate 301 to move longitudinally, thereby adjusting the longitudinal distance between the two sets of battery gripping mechanisms 300 to accommodate polymer power batteries of different sizes.

[0035] In some embodiments of the present invention, the bottom of the anti-collision mounting plate 100 is provided with a guide rail pad 101, which is elongated and installed longitudinally on the bottom of the anti-collision mounting plate 100. The bottom of the guide rail pad 101 is provided with a longitudinal guide rail 102, and two longitudinal sliders 103 are slidably provided on the longitudinal guide rail 102. The longitudinal sliders 103 correspond one-to-one with the nut sliders 216 and are aligned in the lateral direction. The longitudinal sliders 103 and the nut sliders 216 aligned in the lateral direction are respectively connected to the two ends of the pneumatic gripper mounting plate 301 in the lateral direction.

[0036] In some embodiments of the present invention, two sets of gripping manipulators 302 are mounted laterally on the bottom of the pneumatic gripper mounting plate 301, and the two sets of gripping manipulators 302 are arranged in a horizontal row.

[0037] In some embodiments of the present invention, the gripping robot 302 includes a gripper mounting plate 310, a clamping cylinder 320, and a gripper assembly 330. The gripper mounting plate 310 is mounted on the bottom of the gripper mounting plate 301; the clamping cylinder 320 is mounted on the bottom of the gripper mounting plate 310; the gripper assembly 330 includes a pair of grippers 331 arranged laterally opposite each other. The two grippers 330 are respectively mounted on the two clamping ends of the clamping cylinder 320, and the two grippers 331 are closed or opened laterally to grip or release the polymer power battery.

[0038] In some embodiments of the present invention, the gripping manipulator 302 further includes a cylinder protection mechanism 340, which includes a buffer mounting base 341 and a buffer 342. The buffer mounting base 341 is mounted on the lateral side of the clamping cylinder 320; the buffer 342 is mounted on the buffer mounting base 341 and is used to buffer the opening of the clamping end of the clamping cylinder 320.

[0039] In some embodiments of the present invention, the connecting plate 501 is rectangular, with a through hole at each of the four corners. A linear bearing 510 is provided at each through hole, and a set of anti-collision buffer rod assembly 502 is installed on each linear bearing 510. The anti-collision buffer rod assembly 502 includes a spring support sleeve 521, a robot anti-collision guide rod 522, and a spring 523 arranged coaxially. The lower end of the spring support sleeve 521 is connected to the linear bearing 510, and the lower end of the spring support sleeve 521 is connected to the upper end of the spring 523. The lower end of the robot anti-collision guide rod 522 passes through the spring 523, the spring support sleeve 521, the linear bearing 510, and the through hole from top to bottom, and then connects to the anti-collision mounting plate 100 below. The top end of the robot anti-collision guide rod 510 is equipped with an anti-collision pad 524. When the gripping robot is subjected to an upward impact force, the anti-collision mounting plate 100 moves upward as a whole, and the pressure sensor 503 comes into contact with the connecting plate 501 above it. The pressure sensor 503 generates a pressure change, triggering the alarm system, thereby realizing automatic alarm when the battery is collided, which helps to improve the battery yield and prevent the danger of battery fire.

[0040] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
