[0034] The power unit includes an electric guide rail 7, an electric slider 8 and a mounting plate 9; two electric guide rails 7 distributed front and back are installed on the fixed skeleton 4; each electric guide rail 7 is slidably connected with two electric sliders 8 distributed left and right; each electric slider 8 is fixedly connected with a mounting plate 9; each mounting plate 9 is fixedly connected with a motor 10; each support rod 11 is rotatably connected with a mounting plate 9.

[0035] It also includes a contact disc 14, an electric actuator 15 and a detection column 16; the telescopic part of the electric hydraulic press 6 is fixedly connected with the contact disc 14; two symmetric electric actuators 15 are installed on the contact disc 14; the electric actuator 15 is an electric push rod; the telescopic part of each electric actuator 15 is fixedly connected with a detection column 16; all the detection columns 16 are slidably connected with the contact disc 14; the detection column 16 is electrically connected with the control console 1; the detection column 16 is used to contact the power supply wiring of the battery body 001.

[0036] The contact disc 14 is a heat-resistant and corrosion-resistant plate with an upward flanging around the perimeter, which is used to block the scraps or electrolyte of the battery body 001 from staying on the contact disc 14 when the battery body 001 is damaged.

[0037] A multifunctional performance detection method for a mobile phone battery, the specific steps are as follows:

[0038] First, use the first connecting rope 12 and the second connecting rope 13 on the support rod 11 and the electric slider 8 on the same electric guide rail 7 to fix and position the battery body 001 correctly.

[0039] Second, apply pressure to the battery body 001 through the electric hydraulic press 6 to perform a compressive strength test on the battery body 001.

[0040] Third, after the compressive strength test is completed, move the position of the battery body 001, and use the detection column 16 to contact the wiring contact point of the battery body 001, thereby realizing the charge and discharge characteristic test and safety test of the battery body 001.

[0041] Fourth, if the battery body 001 catches fire during the detection process, spray nitrogen through the horizontal pipe 102 to extinguish the fire of the battery body 001, prevent the fire from spreading, and provide safety protection for the battery leakage treatment.

[0042] The working steps of the above embodiment are as follows:

[0043] First, the staff brings the battery body 001 to be detected. Then, the staff opens the hatch 3. Next, the staff places the battery body 001 on the pressure-bearing platform 5 with the wiring contacts of the battery body 001 facing upward. Then, the hatch 3 is closed. After that, the control console 1 is operated. The detection program is set and started on the control console 1. Then, each motor 10 is controlled to start. The rotation directions of the two motors 10 on the same electric guide rail 7 are opposite, synchronously driving the support rods 11 and the corresponding parts thereon to rotate. The two support rods 11 on the same electric guide rail 7 are distributed in a V-shaped pattern. At the same time, the two electric sliders 8 on the same electric guide rail 7 are controlled to move in the direction of approaching each other, synchronously driving the corresponding mounting plates 9 and the parts thereon to move together. When the first connecting rope 12 reaches above the battery body 001 and the second connecting rope 13 has not reached above the battery body 001, the motor 10 is controlled to continue rotating, synchronously driving the support rods 11 and the corresponding parts thereon to rotate, so that the elastic first connecting rope 12 presses on the battery body 001. The battery body 001 is pressed on the pressure-bearing platform 5 by the elastic reaction force of the first connecting rope 12 above, as Figure 5 shown. Then, the motor 10 is controlled to stop. The two electric sliders 8 on the same electric guide rail 7 are controlled to move in the direction of approaching each other, synchronously driving the corresponding second connecting ropes 13 to move. The first connecting rope 12 that has already pressed on the battery body 001 slides along the battery body 001. Then, the second connecting rope 13 contacts the side surface of the battery body 001. At this time, the two rigid second connecting ropes 13 that contact the side surface of the battery body 001 move in the direction of approaching each other, and the two second connecting ropes 13 limit and clamp the battery body 001 to achieve the alignment of the battery body 001. In summary, by fixing the upper part and the left and right sides of the battery body 001, the pre-detection fixing work of the battery body 001 is completed. And by this method, the existing straight-shaped and L-shaped battery bodies 001 can be effectively fixed, ensuring the stability of the battery body 001 during testing, facilitating the performance detection of the battery bodies 001 in the prior art, accurately measuring the force limit of the battery body 001, and having broad practical application prospects.

[0044] Next, control the start of the electro-hydraulic press 6. The electro-hydraulic press 6 extends and exerts a fixed pressure on the battery body 001. By controlling the pressure output by the electro-hydraulic press 6, the compressive performance of the battery body 001 under different pressures can be tested, thereby measuring the force limit of the battery body 001. Then, control the electro-hydraulic press 6 to contract, causing the telescopic part of the electro-hydraulic press 6 and the corresponding parts thereon to move upward. If the battery body 001 is damaged at this time, the damaged battery body 001 is taken out and replaced. Repeat the above operations to test the battery body 001. If the battery body 001 remains intact after the compressive test, continue with the following tests. At this time, the battery body 001 is fixed by the support rods 11, the first connecting rope 12, and the second connecting rope 13. Therefore, control all the electric sliders 8 to move in the same direction together, synchronously driving the corresponding mounting plates 9 and the corresponding parts thereon to move, so that the rigid second connecting rope 13 pushes the battery body 001 to slide on the pressure-bearing platform 5 until the wiring contacts on the battery body 001 reach below one of the detection columns 16. Control all the electric sliders 8 to stop moving. Then, control the electro-hydraulic press 6 to extend, so that the telescopic part of the electro-hydraulic press 6 adheres to the battery body 001. Control the electro-hydraulic press 6 to stop. Then, contract the corresponding electric actuator 15 located above the wiring contacts on the battery body 001, synchronously driving the corresponding detection column 16 to move downward. When the detection column 16 touches the wiring contacts on the battery body 001, the rapid discharge and fast charging performance tests of the battery body 001, as well as the safety tests such as overcharge protection, over-discharge protection, and short-circuit protection of the battery body 001, are started. After the tests are completed, control the electric actuator 15 to extend to reset the detection column 16, and control the electro-hydraulic press 6 to contract. Finally, the staff can open the hatch 3, take away the battery body 001, and replace it with the next test sample for testing.

[0045] The second embodiment: On the basis of the first embodiment, according to Figures 1-2 and Figures 6-8 shown, it further includes a conduit 101, a cross tube 102, and an exhaust pipe 103; the protective shell 2 is connected with two conduits 101 distributed left and right; the support rods 11 are hollow tubes, and each of the two rear support rods 11 is communicated with a conduit 101; a cross tube 102 is commonly communicated between the front and rear corresponding support rods 11; a plurality of nozzles 10201 are opened on each cross tube 102; the rear part of the protective shell 2 is communicated with the exhaust pipe 103.

[0046] The nozzles 10201 on the two cross tubes 102 are symmetrically arranged and are in an inverted V shape when viewed from the front to the back.

[0047] A fire prevention net is arranged on the exhaust pipe 103 for intercepting dust and impurities in the gas.

[0048] It also includes a main pipe 201 and branch pipes 202; the fixed skeleton 4 is connected with a plurality of main pipes 201 evenly distributed at equal intervals in the front and rear directions; each main pipe 201 is provided with a plurality of branch pipes 202; a plurality of seepage holes 5002 are formed in the pressure-bearing platform 5; each branch pipe 202 corresponds to a seepage hole 5002.

[0049] A groove 5001 is formed in the pressure-bearing platform 5 to prevent the liquid from leaking out after the battery body 001 is damaged.

[0050] The working steps of the above embodiment are as follows:

[0051] Considering that during the compressive test of the battery body 001, the battery body 001 may be crushed, which may lead to a fire in the battery body 001. At this time, an external nitrogen tank is connected to the two conduits 101. When a fire occurs during the detection of the battery body 001, the motor 10 is controlled to start, so that the support rod 11 returns to the vertical state, as Figure 7 shown. Then, the nitrogen tank is controlled to pour nitrogen into the hollow support rod 11 through the conduit 101, and then the nitrogen is ejected from the nozzle 10201 of the cross pipe 102. At the same time, the two electric sliders 8 on the same electric guide rail 7 are controlled to approach each other, and the nitrogen is ejected from the symmetrically arranged nozzles 10201 towards the battery body 001, as Figure 7 shown. The nitrogen is purged from both sides of the battery body 001 towards the middle, realizing the isolation of air from both sides to the middle of the battery body 001. This can not only prevent the spread of the fire of the battery body 001, achieve the extinguishing of the battery body 001, but also prevent the battery body 001 from reigniting. Then, an external air circulation machine is connected to the exhaust pipe 103, and the external air circulation machine extracts the air in the protective shell 2 through the exhaust pipe 103 and processes it, effectively avoiding the generation of toxic and harmful gases by the burning of the damaged battery body 001 when replacing the battery body 001, which may irritate the respiratory system of the staff. After observing through the transparent hatch 3 that the smoke in the protective shell 2 has been extracted, the hatch 3 is opened, and the staff wears safety protection equipment, takes away the battery body 001 on the pressure-bearing platform 5, and places it in a designated collection box.

[0052] After removing the battery body 001, to avoid the battery body 001 leaking liquid remaining on the pressure-bearing platform 5 when the above tests are performed on the battery body 001 due to the battery body 001 cracking and not fully burning, a groove 5001 is provided on the pressure-bearing platform 5, effectively preventing the leaked electrolyte from flowing to other positions and causing corrosion of related electrical components. Then, the staff first flushes the groove 5001 with a pressing water flow to try to wash away the remaining leaked liquid, and conducts a preliminary flushing of the groove 5001. The waste water flows into the corresponding branch pipes 202 through each seepage hole 5002. Then, a neutral cleaning liquid is fetched and poured onto the groove 5001 to deeply clean the combustion residues and leaked liquid on the groove 5001. Then, the cleaning waste liquid also flows into the branch pipes 202 through the seepage holes 5002. Finally, the waste liquid converges to each main pipe 201, and waste liquid collection buckets are provided at both ends of the main pipe 201 to collect the cleaning waste liquid and prevent the cleaning waste liquid from polluting the environment.

[0053] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
