[0027] Example

[0028] like Figure 1-5 As shown, this embodiment provides a battery extrusion and penetration testing integrated machine, including an explosion-proof box 1. The explosion-proof box 1 is a frame-type explosion-proof box 1, and the explosion-proof box 1 is provided with a 100mm heat-insulating and explosion-proof layer. The heat-insulating and explosion-proof layer is made of heat-insulating and explosion-proof material. The interior of the explosion-proof box 1 is divided into upper and lower cavities by a partition. The two cavities are a first chamber 101 and a second chamber 102, respectively. A first cabinet door 11 and a second cabinet door 12 are respectively hinged to the opening sides of the first chamber 101 and the second chamber 102. The interior of the first chamber 101 is... An electric cylinder 2 is bolted on and fixedly installed. The electric cylinder 2 is a precision electric cylinder driven by a servo motor. A test box 5 is bolted on and fixedly installed inside the second chamber 102. The test box 5 has an opening on the side near the second cabinet door 12. The output shaft of the electric cylinder 2 passes through the partition and the test box 5 and is fixedly installed with a force sensor 3. A test module 4 is detachably connected to the bottom of the force sensor 3. A pad 6 is fixedly installed inside the test box 5 at a position corresponding to the test module 4. The pad 6 is used to place the battery to be tested.

[0029] Specifically, the test module 4 includes a compression mold 41 and a needle-punching mold 42. The compression mold 41 is used to test the battery under compression, and the needle-punching mold 42 is used to test the battery under puncture. Testers can switch between them as needed.

[0030] In one embodiment, the test box 5 and the explosion-proof box 1 are provided with wiring holes 51 on their sides for wiring tests on the samples.

[0031] In one embodiment, a ventilation duct 53 is fixedly connected inside the explosion-proof box 1, spanning the first chamber 101 and the second chamber 102. A first exhaust port 52 is provided on the side of the test chamber 5, and the first exhaust port 52 is connected to the ventilation duct 53. A fan 54 is bolted to the inside of the explosion-proof box 1, and the input end of the fan 54 is connected to the output end of the ventilation duct 53 through a pipe. A second exhaust port 55 is provided on the side of the explosion-proof box 1, and the output end of the fan 54 is connected to the second exhaust port 55 through a pipe. The gas inside the test chamber 5 is drawn in by the fan 54 and discharged through the first exhaust port 52, the ventilation duct 53, or through the fan 54 from the second exhaust port 55. The second exhaust port 55 can be connected to an air purification device through a pipe to filter the discharged air before it is released.

[0032] In one embodiment, the test chamber 5 has a pressure relief port 561 on its side, and a filter screen is provided at the pressure relief port 561. A pressure relief plate 563 is hinged to the side of the explosion-proof box 1 at a position corresponding to the pressure relief port 561. If the battery inside the test chamber 5 explodes, a high voltage is generated instantaneously. The internal high voltage pushes open the pressure relief plate 563 to release the pressure, and the filter screen intercepts battery fragments, preventing battery fragments from being ejected.

[0033] In one embodiment, a control panel 7 is embedded in the surface of the first cabinet door 11. The control panel 7 is signal-connected to the electric cylinder 2 and the force sensor 3. The control panel 7 includes a display screen and control buttons. A PLC controller is also installed inside the control panel 7. Parameters are input through the control panel 7, and the electric cylinder 2 is controlled to operate through the PLC controller.

[0034] Furthermore, a viewing window 121 is embedded in the middle of the second cabinet door 12. The internal testing situation can be observed through the viewing window 121.

[0035] Furthermore, the bottom of the explosion-proof box 1 is fixedly connected with swivel casters 8. The swivel casters 8 are existing swivel casters with a braking structure, which facilitates the movement of equipment and testing in place.

[0036] The working principle of this utility model is as follows: Open the second cabinet door 12, install the test module 4 below the force sensor 3, install the extrusion mold 41 or the needle punch mold 42 according to the test content, and the replacement only requires removing and installing screws. Place the battery to be tested on the pad 6, close the second cabinet door 12, input the parameters through the control panel 7 on the first cabinet door 11, and the electric cylinder 2 drives the force sensor 3 to move the test module 4 downward to extrude or needle the battery for testing. The battery is qualified if it does not explode or catch fire.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
