Description

Technical Field

[0001] The utility model relates to the technical field of automatic battery cell sorting, in particular to an automatic battery cell sorting device. Background Art

[0002] Battery cell: The battery cell is the smallest unit of the power battery and also the electrical energy storage unit. It must have a high energy density to store as much electrical energy as possible to give electric vehicles a longer range. In addition, the life of the battery cell is also the most critical factor. Damage to any battery cell will cause damage to the entire battery pack.

[0003] For example, a battery cell sorting device with application number CN201821995676.9 includes: a mechanism frame, a negative pressure adsorption plate with adjustable spacing, a material transfer line, a clamping mechanism, a telescopic detection mechanism and a negative pressure adsorption plate. The mechanism frame includes a crossbeam frame and a sliding frame. The negative pressure adsorption plate is slidably connected to the sliding frame. The negative pressure adsorption plate with adjustable spacing includes a first adsorption plate frame, a plurality of first negative pressure adsorption mechanisms, an adsorption mechanism slider and a first frame slider. The material transfer line includes a material transfer line frame, a material placement plate, a sliding rod and a sliding material ejection mechanism. The sliding material ejection mechanism includes a material ejection slider, a material ejection cylinder and a material ejection plate. The battery cell sorting device described in this utility model adopts multiple negative pressure adsorption mechanisms and a lifting and translational transportation method to realize the streamlining of battery cell detection, which not only ensures the accuracy of battery cell detection, but also realizes unmanned operation, greatly improving the detection efficiency. However, when the automatic cell sorting device pushes the cell body, the connecting plate directly pushes the cell body, without a buffer mechanism to absorb the pressure, which can easily cause damage to the cell body. Moreover, after sorting, the cell bodies cannot be neatly arranged inside the classification box. Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and an automatic cell sorting device is proposed. Utility Model Content

[0004] The purpose of the present invention is to provide an automated battery cell sorting device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automated battery cell sorting device, comprising an outer frame and a conveyor belt, a conveyor belt is arranged inside the outer frame, and the top of the conveyor belt is movably connected to the battery cell body, one side of the outer frame is fixedly connected to the conveyor frame, and one side of the conveyor frame is fixedly connected to a pushing mechanism, one side of the pushing mechanism is fixedly connected to a buffer mechanism, and one side of the conveyor frame is provided with a limiting mechanism.

[0006] Preferably, the pushing mechanism includes a servo motor fixedly connected to a position on one side of the conveying frame, and an electric push rod is provided on one side of the servo motor, and one end of the conveying electric push rod is fixedly connected to a through block.

[0007] Preferably, the buffer mechanism includes a push plate fixedly connected to one side of the penetration block, and a buffer block is provided on one side of the push plate, one side of the buffer block is fixedly connected to a connecting plate, and one side of the connecting plate is fixedly connected to a protective layer.

[0008] Preferably, the top end of the conveying frame is fixedly connected to a supporting column, and the top end of the supporting column is fixedly connected to a connecting frame.

[0009] Preferably, the connection frame is movably connected to a driving block inside, and the bottom of the driving block is fixedly connected to a lifting rod.

[0010] Preferably, a clamp is fixedly connected to the bottom of the lifting rod, and classification boxes are fixedly connected to both sides of the conveying frame.

[0011] Preferably, the interior of the classification box is fixedly connected to a limiting mechanism, and the limiting mechanism includes a push rod fixedly connected to a position on one side of the classification box, one end of the push rod is fixedly connected to a push plate, and one side of the push plate is fixedly connected to an insulating plate, and the interior of the classification box is fixedly connected to a decompression pad.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model sets a buffer mechanism and a limiting mechanism. When the battery cell body is pushed, the buffer block inside the buffer mechanism interacts with the buffer spring to reduce the impact force of the pushing mechanism on the battery cell body. The protective layer is made of polyethylene material, and a thin film is formed on the contact surface between the battery cell body and the connecting plate to protect the surface of the battery cell and avoid damage to the battery cell body due to friction. When the traditional sorting device pushes the battery cell body, the connecting plate directly pushes the battery cell body, and there is no buffer mechanism to buffer the pressure, which is easy to cause damage to the battery cell body. Moreover, after the sorting is completed, the battery cell body cannot be neatly placed inside the classification box. The utility model adds a limiting mechanism inside the classification box. When the clamp places the battery cell body inside the classification box, the push rod drives the push rod to push the battery cell body, so that the battery cell body on one side can be attached to the other side of the classification box, which is convenient for storage and arrangement. There is no need for the battery cell body to enter the classification box and be manually placed, thereby improving the automation efficiency.

[0014] 2. The utility model is provided with a pushing mechanism and a driver. When the conveyor belt conveys the battery cell body to the interior of the conveying frame, the servo motor inside the pushing mechanism drives the electric push rod, so that the penetration block pushes the battery cell body at a certain frequency, thereby preventing the battery cell body from piling up at one end of the conveying frame and affecting the conveying efficiency. The interior of the driver is connected to the measuring device inside the fixture. When the fixture contacts the battery cell body, the battery cell body is inspected and the classification is completed. BRIEF DESCRIPTION OF THE DRAWINGS

The pushing mechanism 6 pushes one end of the battery cell body 3, and the buffer mechanism 5 reduces the impact force of the pushing mechanism 6 on the battery cell body 3, thereby protecting the battery cell body 3.

A conveying groove is provided inside the conveying frame 4, and the servo motor 601 drives the electric push rod 602 to drive the through block 603 to move inside the conveying groove at an appropriate frequency.

[0023] Furthermore, the buffer mechanism 5 includes a push plate 501 fixedly connected to one side of the through block 603, and a buffer block 502 is provided on one side of the push plate 501, a connecting plate 503 is fixedly connected to one side of the buffer block 502, and a protective layer 504 is fixedly connected to one side of the connecting plate 503.

The protective layer 504 prevents direct contact between the battery cell body 3 and the connecting plate 503, thereby protecting the battery cell body 3.

[0024] Furthermore, the top of the conveying frame 4 is fixedly connected to a support column 7, and the top of the support column 7 is fixedly connected to a connecting frame 8. The interior of the connecting frame 8 is movably connected to a driving block 9, and the bottom of the driving block 9 is fixedly connected to a lifting rod 10. The support column 7 and the conveying frame 4 are vertically distributed, and a conveying rod is provided inside the connecting frame 8 to support the driving block 9. The lifting rod 10 drives the clamp 11 to clamp the battery cell body 3.
