Description

Technical Field

[0001] This utility model relates to the field of battery extrusion technology, and specifically to a battery extrusion device. Background Technology

[0002] A battery extrusion device is a testing equipment used to simulate the safety performance of batteries under mechanical external forces (such as collisions and extrusions). It is widely used in the research, development, production and safety assessment of new energy batteries.

[0003] Typically, a controlled pressure (usually 1kN to 20kN) is applied to the battery via hydraulic or mechanical drive to test the pressure resistance of the casing, the stability of the internal structure, and the risk of thermal runaway.

[0004] Chinese Utility Model Patent Publication No. "CN 222545125 U" discloses a battery compression device. This device places the battery to be tested between a moving clamp and a stationary clamp. A second electric telescopic rod moves the moving clamp toward the stationary clamp, thereby positioning the battery so that the end of the battery is fixed between the four positioning strips on the baffle. Then, it can be tested by a needle punch assembly, or the battery can be directly compressed by the second electric telescopic rod. That is, the two baffles compress the battery under test, making the battery compression test operation selective and usable according to needs.

[0005] Although the above-mentioned device can adjust the angle of the test battery, it cannot clean up the battery waste after the test and requires manual cleaning, which poses a certain danger. Utility Model Content

A connecting groove 5 is provided on the upper side of the placement platform 3. Two mounting plates 6 are symmetrically fixed in the connecting groove 5. Two spring rods 8 are symmetrically fixed in the front and back of the upper side of the mounting plate 6. The placement plate 7 is slidably connected in the connecting groove 5. The extension end of the spring rod 8 is fixed to the placement plate 7.

[0052] Two movable slots a9 are symmetrically opened on the left and right sides of the upper side of the placement platform 3. Two connecting seats a102 are slidably connected in the two movable slots a9 respectively. Two connecting plates 11 are fixed on the upper side of the two connecting seats a102 respectively. Two connecting frames a13 are rotatably connected to the opposite side of the two connecting plates 11 respectively. Two connecting seats b142 are slidably connected in the connecting frame a13.

Four cylinders b141 drive four clamping plates 143 to move closer together to clamp the front and rear sides of the battery and fix the battery. The servo motor a161 drives gears a162 and b163 to rotate. The rotation of gear b163 drives the connecting frame a13 to adjust its angle, thereby adjusting the angle of the battery.

[0071] When the battery is adjusted at an angle, it will compress the placement plate 7 and the spring rod 8 and retract them into the connecting groove 5. The battery waste that falls into the connecting groove 5 will be pushed out of the connecting groove 5 by the spring rod 8 and the placement plate 7.

[0072] Servo motor b231 drives the circulating screw 232 to rotate. The rotation of the circulating screw 232 causes the connecting seat d233 to move to the left. The leftward movement of the connecting seat d233 causes the cylinder e24 and the extrusion plate 25 to move to the left. The position of the extrusion plate 25 can be adjusted according to actual needs, in conjunction with the angle adjustment mechanism, to facilitate multi-point and multi-angle extrusion tests on the battery.

[0073] Example 3

The telescopic end of the cylinder d201 extends into the slot 21 and is fixedly connected to a fixing seat 202. The fixing seat 202 is slidably connected in the slot 21. The slot 21 is symmetrically opened on the inner walls of the left and right sides of the explosion-proof box 1.

[0076] The waste discharge mechanism includes a cylinder c181 and a rack 183. The cylinder c181 is fixed to the upper side of the power box c17.

[0077] In this embodiment, as Figure 2 and Figure 6 As shown, cylinder d201 drives the fixed seat 202 to move to the lower side of the placement platform 3. The fixed seat 202 limits and supports the placement platform 3. Half of the fixed seat 202 is placed under the placement platform 3, and the other plate is retracted into the slot 21.

[0078] During waste discharge, cylinder d201 drives fixed seat 202 to retract into slot 21, cylinder c181 connects seat c182 and rack 183 to move downward, rack 183 moves downward to drive gear c184 and placement platform 3 to shift to the right by a certain angle, the first clamping mechanism and the second clamping mechanism retract to return to their original positions, and the battery waste falls into waste collection box 4 under its own weight.
