[0036] Please see Figure 1 - Figure 5A pair of second telescopic rods 10202 are inserted into both ends of the test chamber 10201. One end of each pair of second telescopic rods 10202 extends into the interior of the test chamber 10201 and is fitted with a clamping plate 10203. A fire extinguisher 104 is installed on one side of the test chamber 10201. A three-way solenoid valve 106 is fitted onto the output end of the fire extinguisher 104.

The input and output terminals of the second telescopic rod 10202, pressure sensor 10105, grating sensor 10107, and smoke detector 10209 are connected. A door 103 is hinged to one side of the test chamber 10201 via a pair of hinges. The door 103 has a tempered glass observation window. The second telescopic rods 10202, inserted at both ends of the test chamber 10201, extend into the interior and are fitted with clamping plates 10203.

To ensure the smooth conduct of the compression and needle penetration test, a fire extinguisher 104 on one side of the test chamber 10201 is connected to a fire extinguishing nozzle 10208 via a three-way solenoid valve 106. When the smoke detector 10209 detects smoke inside the test chamber 10201, the three-way solenoid valve 106 can be opened, allowing the extinguishing material in the fire extinguisher 104 to be sprayed out through the fire extinguishing nozzle 10208, promptly extinguishing the flames inside the test chamber 10201 and ensuring test safety. A touch panel 105 on one side of the fire extinguisher 104 is connected to the three-way solenoid valve 106, the first telescopic rod 10104, the second telescopic rod 10202, and the pressure... Sensor 10105, grating sensor 10107, and smoke detector 10209 are connected in communication. Operators can conveniently control the operation of each component through the touch panel 105, monitor test data and equipment status in real time, and realize intelligent control and management of the test. The test chamber 10201 has a hinged door 103 on one side, which makes it convenient for operators to place and remove batteries.

[0037] Specifically, the working principle of this battery compression and needle penetration testing machine is as follows: During use, the operator places the battery to be tested into the test chamber 10201 through the chamber door 103 on one side. The second telescopic rods 10202 at both ends of the test chamber 10201 are activated, which moves the sleeved clamping plate 10203 to clamp and fix the battery, ensuring that the battery is stable during the test. The pressing mechanism 101 is activated, and the first telescopic rod 10104 at the center of the upper end of the crossbar 10102 extends and retracts, driving the pressure plate 10 connected to it to extend and retract. 103 slides up and down at the bottom end of the crossbar 10102. A pressure sensor 10105, installed at the center of the bottom end of the pressure plate 10103, is connected to the top of the needle 10207. During the downward pressing of the pressure plate 10103, the pressure sensor 10105 monitors the pressure applied to the needle 10207 in real time, i.e., the squeezing force on the battery. Simultaneously, a grating ruler 10106 on one side of the fixed rod 10101 cooperates with the grating sensor 10107 on one side of the pressure plate 10103 to measure the movement distance of the pressure plate 10103 and provide feedback to the operator. Under the limiting action of the limiting cylinder 10206, the battery is accurately punctured. Waste generated during the test falls into the collection box 10204 through the waste trough at the bottom of the test chamber 10201, and can be discharged through the waste discharge pipe 10205 at the bottom of the collection box 10204. A smoke detector 10209 on the upper side of the test chamber 10201 monitors the smoke situation inside the chamber in real time. If the battery burns and produces smoke during the test, the smoke detector 10209 transmits a signal to the touch panel 105, which then controls the three... When the solenoid valve 106 is opened, the extinguishing material in the fire extinguisher 104 on one side of the test chamber 10201 is sprayed out through the pipe and the fire extinguishing nozzle 10208 to extinguish the flames in the test chamber 10201 in time. The operator can control the three-way solenoid valve 106, the first telescopic rod 10104, and the second telescopic rod 10202 through the touch panel 105, and at the same time read the data fed back by the pressure sensor 10105, the grating sensor 10107 and the smoke detector 10209 in real time, so as to realize intelligent control and management of the entire test process.
