[0002] On the automated assembly line of new energy batteries, multiple groups of battery cells need to be automatically clamped, and the clamped battery cells need to be unlocked when removing and discharging the battery cells. For the clamping method, most of them use a single cylinder, or multiple cylinders are chained for clamping, and then the unlocking method is also to unlock through the cylinder action. The above clamping and unlocking methods are suitable for the clamping of a single product, while for the simultaneous clamping and unlocking of multiple products on a pallet, a set of sophisticated structures needs to be designed to achieve it.

[0003] Patent document CN202310329095.0 discloses a clamping device for manufacturing automobile parts, which relates to the field of mechanical processing technology. The invention includes a base, a fixed clamp is fixedly connected to the top of the base, and a movable clamp is fixedly connected to the outer surface of the base, and the movable clamp is located below the fixed clamp. The workpiece clamped by the fixed clamp is fixed, and the workpiece clamped by the movable clamp can be movable, thereby controlling the angle between the two workpieces. A quick-release pedal is fixedly connected to the bottom of the base. By setting a fixed clamp with a fixed position and a movable clamp with a movable position, the movable clamp can freely adjust the clamping angle of the part under the control of the advance column, the movable clamp bracket and the advance bracket, so as to facilitate clamping; at the same time, the movable clamp can move on the advance bracket, so that the distance between the movable clamp and the fixed clamp can be adjusted to adapt to parts of different sizes; at the same time, the movable clamp can rotate around the welding center driven by the movable clamp bracket, so that the angle between the two parts can be freely adjusted.

[0004] The present invention relates to a mechanism and method for realizing automatic clamping through predetermined track movement, which is used for the automatic locking function on the assembly production line of new energy batteries and electric drives. It uses a single power source and realizes the clamping action through the relative movement of the pin shaft and the moving track on the clamping jaw, so as to solve the automatic clamping demand on the new energy battery electric drive production line. This invention can solve the situation of rotary workpieces, in which the middle hole position can be used for clamping, and when the clamping jaw is released, the workpiece can be easily taken and placed in the vertical direction. It is different from the search patent in terms of usage occasions, structural composition and principle.

[0005] Patent document CN202110902344.1 provides a track lifting inspection robot system, which relates to the field of line patrol robot technology. The track lifting inspection robot system has a hanging track, which fixes the inspection route of the inspection robot and powers the inspection robot at the same time. The power supply system powers the hanging track, thereby driving the robot to patrol along the hanging track. At this time, the smoke sensor starts to work and transmits the smoke content data along the inspection route to the inside of the smoke signal processing system. The information collected by the smoke signal processing system, the light detection processing system, the temperature and humidity detection processing system, and the dust monitoring signal processing system is centrally encrypted by the signal transmission system and sent to the inside of the centralized signal processing system. Through real-time monitoring, the purpose of effectively avoiding losses caused by untimely reporting of inspection results is achieved.

The stopper 1-6 is installed on the inner side of the first conveyor line 1-7. When the pallet is in place, it plays a blocking role and limits the freedom of the pallet to the right along the X direction.

The floating structure and the fixed mechanism are connected by a linear guide rail. The spring guide shaft 2-4 passes through the compression spring 2-6 and is clamped between the first spring guide seat 2-5 and the second spring guide seat 2-7 through the shoulder and the spring. The relative movement between the floating mechanism and the fixed mechanism is achieved through the extension and compression of the spring. The automatic clamping and unlocking of the battery cell is achieved through the relative movement between the floating mechanism and the fixed mechanism.

[0077] The present invention provides another embodiment, a method for automatically unlocking a pallet material clamp of a new energy battery production line.

[0078] Loading position: When the pallet 1-2 is transported to the loading position through the first conveyor line 1-7, the pallet pressure plate 1-4 and the stop 1-6 limit the pallet 1-2, the shooting sensor 1-5 detects the pallet and sends a signal to the PLC, the PLC sends a signal to the solenoid valve, the solenoid valve core switches to control the unlocking cylinder 1-1 piston rod to extend, the cam follower 2-1 contacts the inclined surface of the inclined push block 2-2, the cam follower 2-1 pushes the inclined push block 2-2 to drive the clamping plate mounting seat 2-3 and the parts (floating mechanism) installed thereon to move to the right on the linear guide rail 2-12, at this time the compression spring 2-6 is in a compressed state, and the battery clamping plate 2-9 is in an unlocked state;

[0079] Clamping after loading: After putting in 9PCS battery cells at the same time, the piston rod of the unlocking cylinder 1-1 is retracted. At this time, the elastic force of the four springs of the compression spring 2-6 is used to push the clamping plate mounting seat 2-3 to drive the battery clamping plate 2-9 (floating mechanism) to move to the left on the linear guide rail 2-12, thereby clamping the battery cells at the same time;

[0080] Battery cell unloading position: When the tray 1-2 is transported to the unloading position through the first conveyor line 1-7, the pressure plate 1-4 and the stop 1-6 limit the tray 1-2, and the shooting sensor 1-5 detects the tray and sends a signal to the PLC. The PLC sends a signal to the solenoid valve, and the solenoid valve core switches to control the unlocking cylinder 1-1 piston rod to extend, and the cam follower 2-1 contacts the inclined surface of the inclined push block 2-2.

[0082] The synchronous clamping and unlocking device of multiple groups of battery cells on the tray is realized by the spring compression force and the cylinder cooperation. The displacement of the battery cell clamping plate 2-9 can be modified by modifying the inclined surface size of the inclined surface push block 2-2 to be compatible with different product sizes;

[0083] The synchronous clamping and unlocking device of multiple groups of battery cells on the tray is realized through the cooperation of spring compression force and cylinder. The precision deviation caused by manufacturing and assembly can be eliminated by adjusting the cylinder stroke limit to achieve high clamping accuracy.

[0084] The object of the present invention is to provide a device for synchronously clamping and unlocking multiple groups of battery cells on a tray through the cooperation of spring compression force and cylinder.
