[0002] At present, the country vigorously promotes new energy, and the lithium battery industry has also developed greatly. In this case, the production efficiency of lithium batteries is becoming more and more stringent. In battery production, it is often necessary to transfer materials to different conveying devices, and traditional material collection and discharge are completed by single-axis manipulators, so the working cycle is long, the efficiency is low, and the working distance cannot be adjusted according to the distance of the original device to convey the material. Therefore, there is an urgent need for a lithium battery transfer device that can flexibly change its own spacing and its transfer process is fully automatic.

[0003] In the utility model patent (patent number: CN 207726282 U), a manipulator horizontal material taking device is involved. In this patent, a motor drives a disc to rotate, the disc drives a first connecting rod to rotate, the first connecting rod drives a second connecting rod to rotate, and the second connecting rod drives a connecting block to reciprocate horizontally, so that the receiving box can reciprocate horizontally, and can easily and automatically take materials horizontally. Summary of the invention

[0004] In view of the above problems, the present invention proposes a claw device of a horizontal material taking and variable distance mechanism.

[0005] It comprises a horizontal loading hand-grabbing base plate, which is rectangular; the two opposite sides of the loading hand-grabbing base plate are defined as the front and rear sides, and the other two sides are the left and right sides; a vertical loading hand-grabbing back plate is fixed to the upper surface of the loading hand-grabbing base plate through the loading hand-grabbing position reinforcement ribs; the loading hand-grabbing back plate is connected to the external motion mechanism; a horizontal transfer and lifting plate is connected to the lower part of the loading hand-grabbing base plate through a linear bearing and a guide shaft; a thin cylinder that can be pushed up and down is provided on the upper surface of the loading hand-grabbing back plate; the thin cylinder is connected to the loading hand-grabbing back plate, and the first piston rod at the lower end of the thin cylinder passes downward through the loading hand-grabbing back plate and is connected to the transfer and lifting plate through the piston top; the rear end of the piston top is connected to a variable pitch cylinder mounting plate, and a variable pitch cylinder is provided on the variable pitch cylinder mounting plate; a drag chain bracket is provided at the left end of the transfer and lifting plate, and a drag chain is provided in the drag chain bracket;

[0006] The lower end of the transfer and lifting plate is connected to the variable pitch mounting plate extending left and right, and a vertical vertical guide rail is respectively provided at the left and right ends of the variable pitch mounting plate, and a horizontal horizontal guide rail extending left and right is provided at the bottom of the rear end of the variable pitch mounting plate; a vertical variable pitch cam plate can be slidably connected to the two vertical guide rails up and down, and the middle part of the variable pitch cam plate is connected to the variable pitch cylinder through the second piston rod; the vertical surface of the variable pitch cam plate is provided with a plurality of cylindrical through holes with the spacing decreasing from top to bottom, and the front end of the variable pitch mounting plate is provided with a vertical rib plate, and the rib plate is provided with a three-axis cylinder; the lower end of the three-axis cylinder is connected to the pull rod extending left and right through a transition connecting block, and the lower end of the pull rod is provided with a plurality of left and right flush and magnetic clamping jaw assemblies along the left and right directions, and the clamping jaw assemblies are provided with clamping jaw rollers embedded in the corresponding cylindrical through holes.

[0007] More specifically, the clamping jaw assembly includes two connecting rings, one in front and one in the back. The upper end of the connecting ring is connected to a pull rod, and the lower end is connected to a pressure plate extending forward and backward. The lower end of the pressure plate is connected to a sliding connecting block. The sliding connecting block can be slid left and right to connect to the horizontal guide rail. The lower end of the sliding connecting block is connected to two circular magnets that are flush with each other through a guide rod and a linear bearing. The lower end of the circular magnet is connected to an external lithium battery.

[0008] The working steps of the present invention are:

[0009] (1) The transfer lifting plate is driven by the external motion mechanism to move above the external battery conveying station.

[0010] (2) After the lithium battery at the external battery conveying station is in place, the thin cylinder pushes the transfer lifting plate downward. After external debugging, the program controls the small assembly of the gripper to drop to 1 to 3 mm above the battery. The thin cylinder stops pushing, and the circular magnet descends to the top of the battery and absorbs the battery as the three-axis cylinder descends.

[0011] (3) After the battery is sucked in, the thin cylinder starts to rise, and then separates the lithium battery from the conveying device, and transfers the lithium battery to the next conveying device.

[0012] (4) When the lithium battery is transferred to the top of the next conveyor, the variable pitch cylinder pushes the variable pitch cam plate up and down according to the spacing of the placement stations of the conveyor, driving the clamping jaw roller to slide in the cylindrical through hole of the variable pitch cylinder, so that the battery spacing matches the spacing of the placement stations. After the clamping jaw assembly is pitched, the thin cylinder pushes the transfer lifting plate downward, and the battery is lowered into the battery placement station of the conveyor. The thin cylinder stops descending, and the three-axis cylinder starts to rise, taking the circular magnet away from the lithium battery, and the lithium battery embedded in the placement station falls into the conveyor.

[0013] (5) After the lithium battery is transported, the thin cylinder starts to rise, the lithium battery is completely separated from the gripper assembly, and the lithium battery is transported away by the conveying device.

[0014] Compared with the prior art, the beneficial effects of the present invention are: it has the advantages of simple structure, high flexibility and strong adaptability, can timely adjust the material loading and unloading spacing, and can also be directly and quickly connected to the existing production line to improve the working efficiency of the production line.
