[0002] The soft-pack battery PACK assembly line is a production line used to produce and assemble soft-pack battery packs. Soft-pack batteries are lithium-ion batteries with a flexible shell. Compared with traditional hard-shell batteries, they are lighter, thinner and more flexible. Soft-pack batteries are widely used in electric vehicles, portable electronic devices and energy storage systems.

[0024] The following is combined with Figure 1-6 To further explain this application in detail,

[0025] The present application embodiment discloses a positioning and clamping device for a soft pack battery PACK assembly line.

The two electric cylinders 22 are electrically connected to the PLC controller. By operating the PLC controller, the two electric cylinders 22 drive the slider 23 to move at the same time, and an electric cylinder 24 is fixedly installed on the bottom end of the slider 23. A clamping rod 25 is fixedly installed on the bottom end of the electric cylinder 24, a hollow plate 26 is fixedly installed on the surface of the bottom of the slider 23, a fixed sleeve 27 is fixedly installed on the surface of the hollow plate 26, and a reinforcing rib 28 is fixedly installed on the surface of the fixed sleeve 27. The top end of the clamping rod 25 is slidably connected to the inside of the hollow plate 26, and the end of the reinforcing rib 28 away from the fixed sleeve 27 is fixedly installed on the surface of the slider 23, and the reinforcing rib 28 supports the fixed sleeve 27, so that the fixed sleeve 27 and the hollow plate 26 are more stable.

[0027] Reference Figure 3-Figure 5 The force adjustment component 3 includes a force sensor 31 fixedly installed inside the clamping rod 25, and an electric winding wheel 32 is fixedly installed on the end of the clamping rod 25 away from the force sensor 31. Grooves 33 are provided at the front and rear ends of the clamping rod 25. A rotating rod 34 is rotatably connected inside the groove 33, and an abutment plate 35 is fixedly installed on the surface of the rotating rod 34. A connecting wire 36 is wound around the surface of the electric winding wheel 32, and one end of the connecting wire 36 away from the electric winding wheel 32 is wound around the surface of the rotating rod 34. The electric winding wheel 32 is driven to wind the connecting wire 36, and at this time the connecting wire 36 will pull the rotating rod 34, and at this time the rotating rod 34 drives the abutment plate 35 to rotate.

[0028] Reference Figure 6The positioning assembly 4 includes a fixed rod 41 fixedly installed inside the groove 33, an electromagnet 42 is fixedly installed in the middle of the surface of the fixed rod 41, springs 43 are fixedly installed at the upper and lower ends of the electromagnet 42, a block 44 is fixedly installed at one end of the spring 43 away from the electromagnet 42, a connecting rod 45 is fixedly installed on the surface of the block 44, a pressing plate 46 is fixedly installed at one end of the connecting rod 45 away from the block 44, annular grooves 47 are provided on the upper and lower sides of the surface of the rotating rod 34, the electromagnet 42, the electric cylinder 22 and the force sensor 31 are electrically connected through a PLC controller, the block 44 is slidably connected to the surface of the fixed rod 41, the electromagnet 42 and the block 44 have the same magnetic poles, the pressing plate 46 and the annular groove 47 are in adaptive contact, and the electromagnet 42 will repel the block 44 away from the electromagnet 42 after being energized, and at this time, the block 44 will drive the pressing plate 46 to abut against the inner wall of the annular groove 47, thereby limiting the position of the rotating rod 34.

[0029] Working principle: After the operator places the soft-pack battery in the right position, the electric cylinder 24 is driven to drive the clamping rod 25 to move downward, so that the clamping rod 25 moves to the height to be clamped of the soft-pack battery, and then the operator drives the electric cylinder 1 22 to drive the slider 23 to move in the horizontal direction. At this time, the slider 23 will drive the bottom clamping rod 25 to move slowly in the horizontal direction until the force sensor 31 contacts the outer surface of the battery, and in the process of the movement of the clamping rod 25, the operator drives the electric winding wheel 32 to wind the connecting wire 36, and the connecting wire 36 will pull the rotating rod 34 to rotate, so that the rotating rod 34 drives the abutment plate 35 to rotate, and when the force sensor 31 contacts the surface of the battery, the two abutment plates 35 also rotate to abut on both sides of the battery. At this time, the two groups of abutment plates 35 on the left and right sides firmly limit the left and right sides of the battery. At this time, the electric cylinder 22 drives the clamping rod 25 to move in the direction of the battery, so the reaction force of the battery on the force sensor 31 continues to increase. When the force sensor 31 receives a specified pressure, the force sensor 31 will drive the electric cylinder 22 to stop running through the PLC controller. At this time, the clamping rod 25 no longer continues to squeeze the battery. At the same time, the electromagnet 42 is energized through the control of the PLC controller. At this time, the electromagnet 42 repels the two blocks 44 and moves away from the electromagnet 42. At this time, the block 44 will drive the connecting rod 45 and the pressure plate 46 to move, so that the pressure plate 46 moves and abuts against the inside of the annular groove 47. Therefore, the rotating rod 34 is limited by the pressure plate 46 and cannot continue to rotate. At this time, the abutment plate 35 clamps the battery at the current position to prevent the abutment plate 35 from clamping the battery too hard and causing damage to the battery.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
