DETAILED DESCRIPTION

[0022] Below, the technical solution of the present invention is described in detail through specific embodiments. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation disclosed below.

[0023] like Figures 1 to 5 As shown, an automatic lithium battery cutting device proposed in the present invention includes a frame 1, characterized in that the frame 1 is provided with a loading mechanism 3 for supporting a lithium battery pack 2, a detection mechanism 4 for detecting the polarity of the lithium batteries in the lithium battery pack 2, a pushing mechanism 5 for pushing the loading mechanism 3 to move so that the lithium batteries after the lithium battery pack 2 is cut fall, and a dividing mechanism 6 for dividing the falling direction of the lithium batteries after the lithium battery pack 2 is cut; the detection end of the detection mechanism 4 is telescopically arranged on one side of the pole piece of the lithium battery pack 2, the cutting end of the pushing mechanism 5 is telescopically arranged on one side between adjacent lithium battery packs 2, and the dividing mechanism 6 is arranged at the bottom of the lithium battery pack 2.

[0024] The lithium battery pack includes a plurality of lithium batteries stacked in sequence, and the adjacent lithium batteries are glued together. Therefore, when recycling the lithium battery pack, the lithium battery pack needs to be split into individual lithium batteries. In this embodiment, the lithium battery pack 2 is split by the pushing mechanism 5, and the loading mechanism 3 is pushed at the same time so that the split individual lithium batteries fall according to gravity. Before the splitting, the polarity of the falling lithium battery (resistance and voltage of the lithium battery) is detected by the detection mechanism 4 to judge the quality of the lithium battery. The pushing mechanism 5 guides the lithium battery to the corresponding direction mechanism 6 according to the quality of the lithium battery, so as to realize the splitting and recycling of the lithium battery by category. Therefore, the splitting device can automatically detect the capacity and automatically split the lithium batteries that are stuck together. It is economical and practical, saves a lot of manpower and material resources, and reduces labor costs; it improves the defects of the current use of blades and hammers, which are slow and cost a lot of manpower and material resources.

[0025] In this embodiment, the loading mechanism 3 includes a support plate 31, a pallet 32 ​​and a baffle 33 arranged on the support plate 31. The support plate 31 is fixed on the frame 1. A through hole for placing the lithium battery pack 2 is opened on the support plate 31. The baffle 33 is arranged at the edge of the through hole. The pallet 32 ​​is arranged below the support plate 31 and is fixedly connected to the push plate 52. The lithium battery pack 2 is arranged on the pallet 32 ​​through the through hole.

[0026] The baffle 33 can be made of bakelite, so that the lithium battery pack can be controlled in an upright posture and will not conduct electricity. After a lithium battery is separated, the remaining lithium battery pack on it can be directly lowered vertically onto the support plate 32 for inspection and cutting, which can enable the lithium battery pack to maintain a stable upright posture.

[0027] In this embodiment, the detection mechanism 4 includes a detection cylinder 41 and a probe 42 for detecting the polarity of the lithium battery. The detection cylinder 41 is fixed on the frame 1 , and the telescopic end of the detection cylinder 41 is fixedly connected to the probe 42 .

[0028] Before cutting, the voltage and resistance of the lithium battery to be separated are first tested. The detection cylinder 41 pushes the probe 42 to move toward the positive and negative poles of the lithium battery to be separated. After the two probes 42 contact the positive and negative poles respectively, polarity detection is performed to determine the quality of the current lithium battery, which lays the basis for the subsequent classification of lithium batteries according to quality.

[0029] Specifically, the detection mechanism 4 also includes a flipping plate 43 and a flipping motor 44 for driving the flipping plate 43 to rotate. The flipping motor 44 is fixed on the frame 1, and the bearing seat support frame 45 is fixed on the frame 1. Rotating shafts are set on both sides of the flipping plate 43, and the rotating shafts are inserted into the bearing seat support frame 45 to realize the rotation of the flipping plate 43 set on the frame 1 and set under the support plate 32. The flipping motor 44 is connected to the rotating shaft on the flipping plate 43 through a coupling 46 to drive the rotation of the rotating shaft to drive the rotation of the flipping plate 43.

[0030] The controller 7 controls the turning motor 44 to rotate and drive the turning plate 43 to rotate according to the quality of the lithium batteries, so that one end of the turning plate 43 rotates to the classification frame part corresponding to the direction-dividing mechanism 6, so as to realize the classification of the quality of the lithium batteries, which is convenient for the corresponding different process processing during the subsequent lithium battery recycling, wherein the controller 7 is electrically connected to the electrical control box 8.

[0031] In this embodiment, the pushing mechanism 5 includes a pushing cylinder 51, a pushing plate 52, and a cutter 53 fixed on the pushing plate 52. The pushing cylinder 51 is fixed on the frame 1, the pushing plate 52 is slidably arranged on the frame 1, the telescopic end of the pushing cylinder 51 is fixedly connected to the pushing plate 52, and the cutter 53 is arranged on one side of two adjacent lithium batteries in the lithium battery pack. The pushing mechanism 5 also includes a sweeper 54, a guide rail 55, and a slider 56 slidably connected to the guide rail 55. The sweeper 54 is attached to the cutter 53 and fixed on the frame 1, the guide rail 55 is fixed on the frame 1, and the pushing plate 52 is fixed on the slider 56.

[0032] The controller 7 controls the push cylinder 51 to extend and drives the push plate 52 to move along the direction of the guide rail 55, so that the cutter 53 passes through two adjacent lithium batteries as the push cylinder 51 moves, thereby separating the two glued lithium batteries. Since the glue may stick to the cutter 53, the sweeper 54 needs to be close to the cutter 53. During the retraction of the cutter 53, the cleaning end of the sweeper 54 is used to sweep away the glue that may stick to the cutter 53, and during the retraction of the cutter 53, an air gun is used to blow away and clean the glue, so that the device can work continuously.

[0033] Among them, since the support plate 32 and the cutter 53 are both installed on the same push plate 52, when the cutter 53 cuts through the adhesive between the two lithium batteries, the support plate 32 will leave the lithium battery being cut below, and the lithium battery below will fall down due to gravity after cutting; it should be understood that although the upper lithium battery pack will move downward due to gravity after cutting, it will fall on the cutter 53. As the cutter 53 is retracted, the support plate 32 will also reset to the bottom of the remaining lithium battery pack 2 to support the remaining lithium battery pack 2.

[0034] In this embodiment, the direction-dividing mechanism 6 includes a material unloading bottom plate 61 and a material unloading trough clamping plate 62. The two material unloading bottom plates 61 are fixedly connected by the clamping plate and are V-shaped. The two material unloading bottom plates 61 are arranged below the turning plate 43. The direction-dividing mechanism 6 also includes a material unloading side plate 63, a material unloading trough hanger 64 and a side plate 65. The material unloading side plates 63 are respectively arranged on both sides of the length direction of the material unloading bottom plate 61, and the side plate 65 is arranged at one end of the material unloading bottom plate 61 away from the V-shaped connection. The material unloading trough hanger 64 is rotatably connected to the material unloading trough clamping plate 62.

[0035] The two unloading side plates 63 are respectively arranged on both sides of the unloading bottom plate 61. The unloading bottom plate 61, the side plate 65 and the two unloading side plates 63 form a collecting trough. Qualified lithium batteries or unqualified lithium batteries are collected through the corresponding collecting troughs, and the lithium batteries in the corresponding collecting troughs can be transported to the next process for processing by a robotic arm; the unloading trough hanger 64 can be used to manually adjust the position of the entire diverting mechanism 6 on the one hand, and can also be used to transport the diverting mechanism 6.

[0036] The direction-dividing mechanism 6 divides the lithium batteries into two classification frames according to the quality of the lithium batteries, one is the qualified frame for qualified lithium batteries to enter, and the other is the unqualified frame for unqualified lithium batteries to enter. The unloading areas of the two unloading bottom plates 61 correspond to the qualified product frame and the unqualified product frame respectively. When the detection mechanism 4 detects that the lithium battery is qualified / good, the controller 7 controls the flipping plate 43 to rotate to the top of the unloading bottom plate 61 of the qualified product frame, and the cut lithium batteries fall along the flipping plate 43 to the unloading bottom plate 61, so as to realize the cutting and collection of qualified lithium batteries. Similarly, when the detection mechanism 4 detects that the lithium battery is unqualified / bad, the controller 7 controls the flipping plate 43 to rotate to the top of the unloading bottom plate 61 of the unqualified product frame, and the cut lithium batteries fall along the flipping plate 43 to the unloading bottom plate 61, so as to realize the cutting and collection of unqualified lithium batteries.

[0037] Working process: Place the lithium battery pack on the support plate 32 and keep it upright through the baffle 33, press the start button on the controller 7, if the lithium battery is in place detection sensor, there is an in place signal, indicating that there is a lithium battery waiting to be cut, then the electromagnetic valve of the detection cylinder 41 is opened, the 41 detection cylinder 41 is pushed forward, driving the two probes 42 forward to contact the positive and negative electrodes of the lithium battery respectively, and completing the detection of the quality of the lithium battery. After the detection is completed, a signal is transmitted to the controller 7, and the controller 7 sends a rotation instruction to the flipping motor 44, and the flipping motor 44 rotates, driving the flipping plate 43 to rotate to the top of the qualified unloading bottom plate 61 or the top of the unqualified unloading bottom plate 61.

[0038] After the detection action is completed, the controller 7 controls the push cylinder 51 to move forward, and the push cylinder 51 drives the cutter 53 to move forward along the guide rail 55 until the glue between the two lithium batteries is cut through. After the glue is cut through, since the support plate 32 and the cutter 53 are installed on the same movable plate 52, when the cutter 53 cuts through the glue between the two lithium batteries, the support plate 32 will leave the lithium battery being cut below, and the lithium battery cell below will fall onto the qualified unloading bottom plate 61 or the unqualified unloading bottom plate 61 according to the flipping direction of the flipping plate 43.

[0039] After the cutting action is completed, the controller 7 controls the cutter 53 to retract, and the support plate 32 returns to the position where it can hold the lithium battery pack. The uncut lithium battery pack above falls to the appropriate position on the support plate 32 due to gravity, and the lithium battery in-place detection sensor detects a signal indicating that the lithium battery is ready to be cut on the support plate 32. Repeat the above working process to achieve the cutting and sorting of each lithium battery in the lithium battery pack.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
