[0035] In this embodiment, referring to Figure 5 The lifting assembly 21 includes a support plate 211, a reinforcement mounting plate 212, a guard plate mounting plate 213, a lifting plate 214 and a lifting drive member. The reinforcement mounting plate 212 and the guard plate mounting plate 213 are fixedly connected to the support plate 211, and the reinforcement mounting plate 212 is fixedly connected to the mounting frame 1. The lifting plate 214 is slidably connected to the support plate 211 along the vertical direction. Specifically, the lifting plate 214 is slidably connected to the support plate 211 through a second linear guide 215. The guide rail of the second linear guide 215 is fixedly connected to the support plate 211, and the slider of the second linear guide 215 is fixedly connected to the lifting plate 214. The lifting drive member is installed on the support plate 211 and is used to drive the lifting plate 214 to move. The single-claw anti-collision clamping jaw assembly 22 is installed on the lifting plate 214, so that when the lifting drive member is running, the single-claw anti-collision clamping jaw assembly 22 is driven to move up and down to facilitate clamping and carrying soft-pack batteries.

[0036] Furthermore, the lifting drive component includes a lifting cylinder 216, the fixed end of the lifting cylinder 216 is fixedly connected to the support plate 211, and the movable end of the lifting cylinder 216 is connected to the lifting plate 214. When the lifting cylinder 216 is extended and retracted, it drives the lifting plate 214 to slide up and down, thereby driving the single-jaw anti-collision clamp assembly 22 to move up and down.

[0037] In other embodiments, the lifting drive member may be a lifting motor, a linear module, etc., to provide power to drive the lifting plate 214 to perform linear motion.

[0038] In this embodiment, referring to Figure 6 and Figure 7The single-jaw anti-collision clamping jaw assembly 22 includes a clamping jaw, a clamping jaw mounting plate 222, a single-jaw assembly mounting plate 221, a slot-shaped photoelectric device 229, and a sensor sheet 228. The single-jaw assembly mounting plate 221 is fixedly connected to the lifting plate 214, and the clamping jaw mounting plate 222 is slidably connected to the single-jaw assembly mounting plate 221 along the vertical direction. Specifically, the clamping jaw mounting plate 222 is slidably connected to the single-jaw assembly mounting plate 221 via a first linear guide 223. The slider of the first linear guide 223 is fixedly mounted on the clamping jaw mounting plate 222, and the slide rail of the first linear guide 223 is fixedly connected to the single-jaw assembly mounting plate 221, thereby allowing the clamping jaw mounting plate 222 to stably move on the single-jaw assembly mounting plate 221. The clamping jaw is fixedly connected to the clamping jaw mounting plate 222, so that when the clamping jaw is subjected to external force, the clamping jaw mounting plate 222 is driven to move. The slot-shaped photoelectric 229 is installed on the single-grip assembly mounting plate 221, and the sensing plate 228 is installed on the gripper mounting plate 222, and the sensing plate 228 is located in the slot-shaped photoelectric 229. When the gripper mounting plate 222 moves, the sensing plate 228 moves relative to the slot-shaped photoelectric 229, thereby determining whether the gripper collides with other objects.

[0039] Furthermore, the clamp includes a second clamping finger cylinder 224 and a clamping claw piece 225 connected to the two movable clamping fingers of the second clamping finger cylinder 224. The second clamping finger cylinder 224 is fixedly mounted on the clamp mounting plate 222. When the second clamping finger cylinder 224 is running, it drives the two clamping claw pieces 225 to move closer and apart to facilitate clamping or releasing the soft-pack battery.

[0040] Furthermore, the second clamping cylinder 224 is connected to a first magnetic switch 227, and the clamping claw piece 225 is provided with a radiation sensor 226, which can detect the presence of a soft-pack battery through the radiation sensor 226, thereby controlling the movement of the second clamping cylinder 224 through the first magnetic switch 227.

[0041] In this embodiment, referring to Figure 6 and Figure 7An elastic reset member is provided on the single clamping jaw assembly mounting plate 221, and the elastic reset member is used to drive the clamping jaw mounting plate 222 to move and then reset so that the sensing plate 228 is located in the slot-shaped photoelectric 229. Specifically, the elastic reset member includes an anti-collision plate 2210, a guide rod 2211 and an elastic member, the anti-collision plate 2210 is fixedly connected to the single clamping jaw assembly mounting plate 221, a guide hole is provided on the anti-collision plate 2210, the guide rod 2211 is fixedly connected to the clamping jaw mounting plate 222, and the guide rod 2211 is slidably connected to the guide hole, the elastic member is connected between the anti-collision plate 2210 and the clamping jaw mounting plate 222, and the elastic member is a spring 2212, the spring 2212 is sleeved on the outside of the guide rod 2211, and the two ends of the spring 2212 are respectively connected to the anti-collision plate 2210 and the clamping jaw mounting plate 222, when the spring 2212 is in a natural state (under the gravity of the clamping jaw and the clamping jaw mounting plate 222), ), the sensing piece 228 is located in the slot-type photoelectric 229. When the clamping jaws clamp the soft-pack battery, after the clamping jaws abut against the feeding mechanism of the soft-pack battery, the clamping jaws are subjected to an impact force that can compress the spring 2212, which drives the clamping jaw mounting plate 222 to move upward, and the sensing piece 228 leaves the slot-type photoelectric 229. The slot-type photoelectric 229 cannot sense the sensing piece 228. The alarm device connected to the slot-type photoelectric 229 sounds an alarm or stops the operation of the lifting cylinder 216 through the controller to avoid the clamping jaw from being damaged by impact. At this time, the spring 2212 is compressed. When the lifting cylinder 216 drives the single-jaw anti-collision clamping jaw assembly 22 to move upward, under the restoring force of the spring 2212, the clamping jaw mounting plate 222 moves downward and resets, so that the sensing piece 228 returns to the slot-type photoelectric 229.

[0042] In this embodiment, referring to Figure 8 The guard plate assembly 23 includes a first clamping finger cylinder 231 and two guard plates 232 connected to the two movable clamping fingers of the first clamping finger cylinder 231. The fixed end of the first clamping finger cylinder 231 is installed on the guard plate mounting plate 213. The first clamping finger cylinder 231 is provided with a second magnetic switch. When the second magnetic switch senses that the soft-pack battery clamped by the clamping claw rises to a predetermined height, it controls the first clamping finger cylinder 231 to drive the two guard plates 232 to approach and clamp, and the guard plates 232 protect the soft-pack battery.

[0043] The steps of the soft-pack battery clamping device of the present invention for clamping the soft-pack battery are as follows: the operation of the lifting cylinder 216 drives the single-claw anti-collision clamping claw assembly 22 to move downward, and when the third magnetic switch set on the lifting cylinder 216 senses in place, it indicates that the lifting cylinder 216 has dropped to the preset position, and then the air bag of the soft-pack battery is sensed by the cross-beam sensor 226 and a command is sent to the second clamping finger cylinder 224, and the second clamping finger cylinder 224 performs a clamping action to drive the two clamping claws 225 to clamp the air bag of the soft-pack battery, wherein the two single The jaws of the anti-collision jaw clamp respectively clamp the air bags on both sides of the soft-pack battery. After the first magnetic switch 227 senses in place, it indicates that the second clamping finger cylinder 224 has been clamped, and then the lifting cylinder 216 drives the single-jaw anti-collision jaw assembly 22 to move upward. After the second magnetic switch senses in place, it indicates that the soft-pack battery has risen to the preset position. At this time, the first clamping finger cylinder 231 performs a clamping action, driving the guard plate 232 to protect the soft-pack battery body, and then the transportation mechanism connected to the mounting frame 1 drives the entire soft-pack battery clamping device to move to transport the soft-pack battery.
