Description

Technical Field

[0001] This invention relates to battery cell delivery equipment, and more particularly to a magnetic levitation delivery line. Background Technology

[0002] Currently, lithium battery production typically requires a conveyor line to transport cells or batteries to designated workstations for processing. At these workstations, the cells, which are normally clamped, need to be unclamped to facilitate processing. However, existing unclamping mechanisms require a magnetic levitation fixture to stop in the conveyor position before unclamping can begin, which prolongs the overall conveying time and reduces the efficiency of cell processing. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a magnetic levitation conveyor line.

[0004] The objective of this invention is achieved through the following technical solution: a magnetic levitation conveyor line, comprising a magnetic levitation rotor conveyor track and a magnetic levitation fixture capable of sliding along the magnetic levitation rotor conveyor track, the magnetic levitation fixture comprising a fixture plate, the fixture plate being provided with a fixed lower clamping plate, a movable upper clamping plate, a first fixture air inlet and a second fixture air inlet, the movable upper clamping plate being provided with pressure by a magnetic spring assembly to clamp the battery cell; the magnetic spring assembly being provided with a cam follower; The magnetic levitation motor conveying track is provided with an air-receiving and opening mechanism at the opening station. The air-receiving and opening mechanism includes an opening mounting plate, a cam groove plate on the opening mounting plate, and an opening guide rail on one side of the opening mounting plate. A first air-receiving component and a second air-receiving component are slidably arranged on the opening guide rail.

[0005] As an improvement of the magnetic levitation conveyor line of the present invention, the first air receiving component includes a first side plate and a first vacuum air receiving cylinder. The piston rod end of the first vacuum air receiving cylinder is connected to the first side plate. The first side plate is provided with a first lifting and avoiding cylinder and a first lifting guide rail. The piston rod end of the first lifting and avoiding cylinder is provided with a first air receiving nozzle mounting plate. The first air receiving nozzle mounting plate is provided with a first air receiving nozzle.

[0006] As an improvement of the magnetic levitation conveyor line of the present invention, the second air receiving component includes a second side plate and a second vacuum air receiving cylinder. The piston rod end of the second vacuum air receiving cylinder is connected to the second side plate. The second side plate is provided with a second lifting and avoiding cylinder and a second lifting guide rail. The piston rod end of the second lifting and avoiding cylinder is provided with a second air receiving nozzle mounting plate. The second air receiving nozzle mounting plate is provided with a second air receiving nozzle.

[0007] As an improvement of the magnetic levitation conveyor line of the present invention, a cam groove is provided on one side of the cam groove plate. The cam groove has a high position, a first low position and a second low position. When the follower cam slides from the first low position to the high position, the first air inlet is connected to the first fixture air inlet. When the follower cam slides from the high position to the second low position, the second air inlet is connected to the second fixture air inlet, and the first air inlet is separated from the first fixture air inlet.

[0008] As an improvement to the magnetic levitation conveyor line of the present invention, one end of the movable upper clamp is connected to a lifting slide plate, which is connected to the fixture plate via a slide rail and a slider. The magnetic spring assembly includes a magnetic rod and a cylindrical magnetic spring. The cylindrical magnetic spring is sleeved on the magnetic rod. The upper and lower ends of the magnetic rod are respectively connected to the lifting slide plate through fixing blocks. The cam follower is installed on the fixing block at the lower end.

[0009] As an improvement to the magnetic levitation conveyor line of the present invention, a first slider mounting plate is provided on one side of the fixture plate, and a first slider is provided on the first slider mounting plate. The first slider is slidably connected to the side slide rail of the magnetic levitation motor conveyor track.

[0010] As an improvement to the magnetic levitation conveyor line of the present invention, the bottom of the fixed lower clamp is provided with a second slider mounting plate, the second slider mounting plate is provided with a second slider, and the second slider is slidably connected to the upper slide rail of the magnetic levitation moving part conveyor track.

[0011] As an improvement to the magnetic levitation conveyor line of the present invention, the fixed lower clamp is provided with a plurality of adsorption holes at intervals, the fixed lower clamp is provided with a cavity, the adsorption holes are connected to the cavity, the fixture plate is provided with a vacuum channel, and the cavity is connected to the first fixture air inlet and the second fixture air inlet through the vacuum channel.

[0012] As an improvement to the magnetic levitation conveyor line of the present invention, when the magnetic levitation fixture opens, it slides along the magnetic levitation mover conveyor track to the position of the air-connecting opening mechanism. Before the magnetic levitation fixture opens, a vacuum is required to hold the battery cell in place to prevent displacement during movement. Before entering the cam groove, the first vacuum air-connecting cylinder is in an extended state, and the second vacuum air-connecting cylinder is in a retracted state. The pressure of the first and second vacuum air-connecting cylinders is controlled by a pressure reducing valve, which acts as a gas spring. The first fixture air-connecting nozzle connects to the first air-connecting nozzle and enters the cam groove together with the movement of the magnetic levitation fixture. When the cam follower reaches the high point of the cam groove, the magnetic levitation fixture is fully opened. The second fixture air inlet is connected to the second air inlet. At this time, the first air inlet disconnects the vacuum, the first vacuum air inlet cylinder fully retracts and disengages from the first fixture air inlet, the first lifting and avoidance cylinder descends, and the first vacuum air inlet cylinder extends and returns to its original position. After the battery cell completes its operation at the working position, the second air inlet opens the vacuum and holds the battery cell. The magnetic levitation mover conveying track drives the magnetic levitation fixture to begin moving from the high point of the cam groove to the second low point, completing the clamping action. The cam follower comes out of the cam groove and waits at the next working position. The second vacuum air inlet cylinder fully extends and disengages from the second fixture air inlet, the second lifting and avoidance cylinder descends, and the second vacuum air inlet cylinder retracts and returns to its original position, completing the entire air inlet cycle.

[0013] The beneficial effects of this invention are as follows: This invention enables clamping to occur during the movement of the magnetic levitation fixture, improving the production efficiency of the battery cells. It eliminates the need for waiting and significantly reduces the dwell time required for clamping. This invention features an air-feeding clamping mechanism at the clamping station on the magnetic levitation mover conveyor track. This mechanism not only opens the magnetic levitation fixture but also vacuum-adsorbs the clamped battery cells, preventing them from moving and eliminating the need for a secondary positioning process, thus improving the processing efficiency of the battery cells.
