Abstract
Description
Technical Field
[0001] The utility model relates to the field of lithium battery processing equipment, in particular to a double-layer detection mechanism for pressure and insulation of aluminum shell batteries. Background Technique
[0002] The existing lithium batteries generally use a conveyor belt to test the aluminum shell of the lithium battery. However, when using the conveyor belt for testing, an additional mechanism is required for the actual top surface test, and it is impossible to simultaneously test the six faces of a rectangular lithium battery.
[0003] Therefore, the testing efficiency is affected. Especially for lithium batteries with a relatively large volume, there are also some problems that do not meet the requirements when using belt transportation, such as a relatively large friction coefficient.
[0004] Therefore, how to achieve the insulation and pressure testing of lithium batteries is the key to the design. Summary of the Invention
[0005] The main purpose of the utility model is to propose a double-layer detection mechanism for pressure and insulation of aluminum shell batteries, aiming to achieve the pressure and insulation testing of lithium batteries, with fast testing speed and the ability to simultaneously test six faces.
[0006] To achieve the above purpose, the utility model proposes a double-layer detection mechanism for pressure and insulation of aluminum shell batteries, including:
[0007] A horizontal moving frame, which is respectively provided with a first detection station, a loading / unloading station, and a second detection station;
[0008] The structures of the first detection station and the second detection station are the same, including a top testing device and two adjacent side testing devices;
[0009] The horizontal moving frame includes two horizontally spaced guide rails, a horizontal slider disposed between the horizontal guide rails, and a driving device for driving the movement of the carrier. The horizontal slider is provided with a carrier,
[0010] The carrier is provided with two spaced positioning bases for placing lithium batteries. The two positioning bases are respectively a first positioning base and a second positioning base. The first positioning base corresponds to the first detection station, and the second positioning base corresponds to the second detection station.
[0011] The positioning base is provided with side positioning seats that cooperate with the two side testing devices (one of the side positioning seats is integrally formed with the positioning base, and the other side positioning seat is slidably arranged).
[0012] In actual tests, when the first positioning base moves to the first detection station, the second positioning base is at the loading and unloading position. Then, the manipulator can take out the detected lithium battery located on the second positioning base, and another manipulator can place the undetected lithium battery on the second positioning base.
[0013] When the lithium battery located on the first positioning base has been detected, the first positioning base moves to the loading and unloading position, and then the second positioning base moves to the second detection station, repeating the above steps.
[0014] It has a simple structure and can effectively achieve full inspection of the aluminum shell, effectively improving the detection efficiency and ensuring the safety of the lithium battery.
[0015] Among them, the side test device and the side positioning seat cooperate to realize the detection of the outer peripheral side of the limited lithium battery.
[0016] Among them, the positioning base and the top test device cooperate to realize the test of the bottom and top surfaces of the aluminum shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] As Figures 1 to 4 shown, an aluminum shell battery pressure insulation double-layer detection mechanism includes:
[0033] A horizontal moving frame 1, and the horizontal moving frame 1 is respectively provided with a first detection station, a loading / unloading position, and a second detection station;
[0034] The structures of the first detection station and the second detection station are the same, and each includes a top testing device 2 and two adjacent side testing devices 3;
[0035] The horizontal moving frame 1 includes two horizontally spaced guide rails 11, a horizontal slider 12 provided between the horizontal guide rails 11, and a driving device 13 for driving the carrier 10 to move. The horizontal slider 12 is provided with the carrier 10.
[0036] The carrier base 10 is provided with two spaced positioning bases for placing lithium batteries. The two positioning bases are respectively a first positioning base 41 and a second positioning base 42. The first positioning base 41 corresponds to the first detection station, and the second positioning base 42 corresponds to the second detection station.
[0037] The positioning base is provided with side positioning seats 5 that cooperate with the side testing devices 3 on both sides (one of the side positioning seats 5 is integrally formed with the positioning base, and the other side positioning seat 5 is slidably arranged).
[0038] In actual testing, when the first positioning base 41 moves to the first detection station, the second positioning base 42 is located at the loading and unloading position. The manipulator can take out the lithium battery that has been detected on the second positioning base 42, and another manipulator can place the undetected lithium battery on the second positioning base 42.
[0039] When the lithium battery on the first positioning base 41 has been detected, the first positioning base 41 moves to the loading and unloading position, and then the second positioning base 42 moves to the second detection station, repeating the above steps.
[0040] Its structure is simple, and it can effectively achieve full inspection of the aluminum shell, effectively improving the detection efficiency and ensuring the safety of the lithium battery.
[0041] Among them, the side testing device 3 and the side positioning seat cooperate to realize the detection of the outer periphery of the limited lithium battery.
[0042] Among them, the positioning base cooperates with the top testing device 2 to realize the testing of the bottom and top surfaces of the aluminum shell.
[0043] Specifically, the top testing device 2 includes a frame 20, a hydraulic cylinder 21 arranged on the top of the frame 20, and a top plate 22 connected to the hydraulic cylinder 21. The wall surface of the top plate 22 in contact with the lithium battery is an electrode surface. When the hydraulic cylinder 21 applies a predetermined downward pressure to the lithium battery, generally through a predetermined gap. For example, if the thickness of the lithium battery is 100 mm, then the distance between the upper wall of the positioning base and the top plate 22 is greater than 100 mm (such as +0.01). This test will neither damage the aluminum shell, and at the same time, it can clearly obtain whether there is damage to the insulating layer after spraying the insulating paint, and at the same time, it can test its pressure withstand value. The side mainly tests insulation.
[0044] In the embodiment of the present invention, the side testing device 3 includes a first telescopic motor and a test plate 32 that cooperates with the first telescopic motor 31. The test plate is a first electrode surface.
[0045] Specifically, the side positioning seat is provided with a second electrode surface that cooperates with the first electrode surface. That is, in actual tests, a predetermined system is generally provided. The positive electrode can be inserted into the inner wall of the housing, and then the electrode surface serves as the receiving end. When the insulating layer is less than the predetermined value and the voltage is continuously rising, the predetermined electrode surface conducts, indicating that the paint surface does not meet the standard.
[0046] In the embodiment of the present invention, the side positioning seat is fixedly arranged or slidably mounted on the slider.
[0047] Specifically, the slider is provided with a driven guide rail, and the side positioning seat is slidably mounted on the driven guide rail 61. The slider is provided with a second telescopic motor 6. That is, the side positioning seat corresponds to the test board, and then it can be determined whether the predetermined paint surface meets the insulation requirements.
[0048] Of course, one group of the side positioning seats can be fixed and the other group can be slidable.
[0049] Specifically, the driving device 13 includes a ball screw disposed between two horizontal guide rails 11, a screw nut disposed on the slider, and a rotating motor that cooperates with the ball screw. The ball screw and the screw nut cooperate to achieve precise movement of the slider.
[0050] In the embodiment of the present invention, the width of the positioning base is less than the width of the lithium battery. An avoidance position 43 is formed between the positioning base and the lithium battery. The side positioning seat and the test board are respectively provided with bending portions 44 extending into the avoidance position 43, which facilitates the clamping of the manipulator.
[0051] Specifically, manipulators 200 are respectively provided on both sides of the loading and unloading position, which are responsible for loading and unloading, avoiding mechanism interference.
[0052] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
