Description

Technical Field

[0001] This invention relates to the field of automated mass production technology for batteries, and in particular to a sealed battery air bag handling device and its robotic arm mechanism. Background Technology

[0002] In actual production, newly manufactured batteries need to be air-sealed after handling to prevent potential leaks and safety hazards. Typically, battery handling and air-sealing require specialized handling and sealing mechanisms, which are inefficient, costly, and detrimental to automated mass production. The best improvement would be to develop automated battery handling equipment with air-sealing capabilities. This would not only reduce the workload and operate stably in complex environments, but also seal the battery air bags during handling. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes a sealed battery air bag handling device and its robotic arm mechanism.

[0004] This invention proposes a robotic arm mechanism for handling sealed battery gas bags, comprising a rectangular mechanical base plate. Two parallel sides of the base plate extend in the front-back direction, and the other two parallel sides extend in the left-right direction. A bidirectional lead screw extending in both directions is fixed to the lower surface of the base plate via a lead screw mounting seat. Two lead screw seats, which change distance with the lead screw's side spacing, are mounted on the bidirectional lead screw. A lead screw motor is fixed to the left end of the upper surface of the base plate. A synchronous pulley is located at the right end of the bidirectional lead screw and the lead screw motor, connected by a synchronous belt, allowing the two lead screw seats to change their left-right distance under the drive of the lead screw motor. The lower surfaces of the two lead screw seats are respectively provided with first slide rails in the front-back direction. A gripper cylinder mounting seat is slidably mounted at the front and rear ends of each first slide rail. A gripper cylinder is connected to the lower surface of the gripper cylinder mounting seat, and a gripper cylinder is connected to the lower surface of the gripper cylinder mounting seat. The mechanical grippers close at the rear, and each gripper has a clamping clip for securing the battery gas bag. The bottom of the grippers is fitted with silicone gripper material to prevent scratching the battery gas bag seal. The mechanical base plate is connected downwards to an adjusting cylinder mounting plate via mounting plates on the front and rear sides, positioning the adjusting cylinder mounting plate below a bidirectional lead screw. The lower surface of the adjusting cylinder mounting plate has a second slide rail in the front-to-back direction. The front and rear ends of the second slide rail are slidably connected to a movable plate extending in the left-to-right direction. The two movable plates are respectively connected to two rows of gripper cylinder mounting seats. An adjusting cylinder is connected to the middle of the two movable plates, and this cylinder can be pushed back and forth to change the distance between the movable plates. The movable plates have a sealing gripper mechanism parallel to the left and right mechanical grippers, which can be used for heating and sealing the battery gas bag. The mechanical base plate has a control mechanism for electrical control.

[0005] More specifically, the sealing gripper mechanism includes a sealing mounting plate connected to the movable plate. The sealing mounting plate is connected to a sealing cylinder that can be pushed up and down by a lifting cylinder. The lower surface of the sealing cylinder is provided with two vertical sealing heating fixing plates that can close together with the sealing cylinder. Two heating rods are inserted through the sealing heating fixing plates in the left and right directions. A heating plate is provided inside the air bag clamping position formed by the sealing heating fixing plates. The sealing heating fixing plates are provided with leaf springs for guiding when clamping the battery sealing edge.

[0006] More specifically, the sealed heating fixing plate uses an insulating, high-temperature resistant, low thermal conductivity material. The heating plate is made of a high-hardness material with relatively low specific heat capacity that is resistant to high temperatures and electrolyte corrosion.

[0007] More specifically, the control mechanism includes a booster pump, a solenoid valve island, a pressure regulating valve, and a temperature controller. The booster pump's inlet is connected to an external air source connector, and its outlet is connected to the inlet of a solenoid valve island. The solenoid valve island's outlet is connected to the inlet of the pressure regulating valve, and the pressure regulating valve's outlet is connected to the gripper cylinder to control the gripper cylinder's clamping force. The booster pump can increase the clamping force of the air bag in the sealing gripper mechanism by increasing the clamping force of the gripper cylinder, or it can meet the air bag sealing clamping force requirements by selecting a gripper cylinder with a larger outer diameter clamping force. One end of the temperature controller is connected to an external power source, and the other end is connected to a temperature sensor inside the heating rod to detect the heating rod temperature and control the air bag sealing temperature.

[0008] This invention proposes a drive mechanism for a sealed battery airbag battery transport device. The bottom consists of four vertical columns of equal height, arranged at the four endpoints of a rectangle on a horizontal plane. One side of this rectangle extends in the left-right direction, and the direction perpendicular to the left-right direction is defined as the front-back direction. The top of each column is connected to a first module via a first support plate. The first module extends in the front-back direction and connects to the tops of the left and right columns. A second module extending in the left-right direction is slidably connected to the two first modules via a second support plate. A third support plate is slidably connected to the second module in the left-right direction. The third support plate connects to a vertically aligned third module. An external mechanical structure that can slide up and down is connected to the third module. Each of the first, second, and third modules is equipped with a reducer to control module rotation and a geared motor to drive the reducer, allowing the external mechanical structure to be controlled to move up, down, left, right, forward, and backward.

[0009] More specifically, a horizontal connecting rod is added between the first modules that move synchronously to ensure the synchronization of the two first modules.

[0010] The present invention proposes a sealed battery air bag transport device, which includes a robotic arm mechanism and a drive mechanism;

[0011] The drive mechanism has four vertical columns of equal height at its bottom. The bottom of each column is arranged at the four endpoints of a rectangle on a horizontal plane, with one side of the rectangle extending in the left-right direction and the perpendicular direction to the left-right direction defined as the front-back direction. The top of each column is connected to a first module via a first support plate. The first module extends in the front-back direction and connects to the tops of the left and right columns. A second module extending in the left-right direction is slidably connected to the two first modules via a second support plate. A third support plate is slidably connected to the second module in the left-right direction. The third support plate connects to a vertical third module. A manipulator mechanism that can slide up and down is connected to the third module. Each of the first, second, and third modules is equipped with a reducer to control the sliding of the module and a geared motor to drive the reducer, so that the manipulator mechanism can be controlled to move up, down, left, right, forward, and backward.

[0012] The robotic arm mechanism includes a rectangular mechanical base plate, which is slidably connected to the third module. A bidirectional lead screw extending laterally is fixed to the lower surface of the mechanical base plate via a lead screw mounting seat. Two lead screw seats with variable pitch are mounted on the bidirectional lead screw. A lead screw motor is fixed to the left end of the upper surface of the mechanical base plate. A synchronous pulley is located at the right end of the bidirectional lead screw and the lead screw motor, connected by a synchronous belt, allowing the two lead screw seats to change their lateral distance under the drive of the lead screw motor. The lower surfaces of the two lead screw seats are respectively provided with a first slide rail in the front-to-back direction. A gripper cylinder mounting seat is slidably mounted at the front and rear ends of each first slide rail. A gripper cylinder is connected to the lower surface of the cylinder mounting base. A mechanical gripper, which can close and retract with the gripper cylinder, is connected to the lower surface of the cylinder mounting base. The mechanical gripper is equipped with a battery gas bag fixing clamp for securing the battery gas bag. The bottom of the mechanical gripper is equipped with silicone gripper material to prevent scratching the battery gas bag seal. The mechanical base plate is connected downwards to an adjusting cylinder mounting plate via mounting plates on the front and rear sides, positioning the adjusting cylinder mounting plate below a bidirectional lead screw. The lower surface of the adjusting cylinder mounting plate has a second slide rail in the front-to-back direction. The front and rear ends of the second slide rail are slidably connected to a movable plate extending in the left-to-right direction. The two movable plates are respectively connected to the front and rear rows of gripper cylinder mounting bases. A centrally connected adjusting cylinder can be pushed back and forth to change the distance between the front and rear movable plates. The movable plates are equipped with a sealing gripper mechanism parallel to the left and right mechanical grippers, which can be used for heating and sealing the battery air bag. The sealing gripper mechanism includes a sealing mounting plate connected to the movable plate.

Two vertical sealing heating fixing plates are provided on the lower surface of the sealing cylinder, which can close back and forth with the sealing cylinder.

[0013] The workflow of this invention is as follows:

[0014] (1) The robotic arm mechanism positions the battery at one end of the drive device and moves downward through the movement of the drive device.

[0015] (2) The mechanical gripper grasps the battery and moves it up and down, forward and backward, and left and right through the movement of the first, second and third modules, automatically moving the battery to the target. At the same time, during the movement of the mechanical gripper mechanism to grasp the battery, the sealing gripper mechanism is simultaneously lowered by the lifting cylinder, and the sealing gripper clamps the battery air bag to complete the heating and sealing of the battery air bag;

[0016] (3) The robotic arm clamps the battery to the end point of the transport, and the sealing jaws and mechanical jaws release and lower the battery in turn, completing the transport and air bag sealing.
