Description

Technical Field

[0001] The utility model relates to a battery voltage detection device, in particular to a lithium iron phosphate battery voltage detection device. Background Art

[0002] Lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. During the charging process, some lithium ions in the lithium iron phosphate are released, transferred to the negative electrode through the electrolyte, and embedded in the negative electrode carbon material; at the same time, electrons are released from the positive electrode and reach the negative electrode from the external circuit to maintain the balance of the chemical reaction. During the discharge process, lithium ions are released from the negative electrode and reach the positive electrode through the electrolyte. At the same time, the negative electrode releases electrons and reaches the positive electrode from the external circuit to provide energy to the outside world.

[0021] Embodiment: A lithium iron phosphate battery voltage detection device, such as Figure 1-5As shown, it includes a base 1, a support frame 2, a voltage detection meter 3, a first support member 4, a first electric push rod 5, a voltage detector 6, a first support block 7, a first rotating shaft 8, a first servo motor 9, a first flat belt 10, a limit plate 11, a second support member 12, a second electric push rod 13, a blocking frame 14, a sliding plate 16 and a spring 15. A support frame 2 is welded to the top of the middle of the base 1, a voltage detection meter 3 is fixedly installed on the front side of the top of the support frame 2, two first support members 4 are symmetrically fixed to the front side of the top of the support frame 2, a first electric push rod 5 is installed between the front and rear corresponding support members, a voltage detector 6 is fixed to the telescopic rod of the first electric push rod 5, two first support blocks 7 are symmetrically fixed to the top of the support frame 2, and the first rotating shaft 8 is rotatably connected between the left and right corresponding first support blocks 7, and the front A first servo motor 9 is installed on the first support block 7 on the left side of the part, and the output shaft of the first servo motor 9 is connected to the first rotating shaft 8 at the front. A first flat belt 10 is wound between the two first rotating shafts 8, and a limit plate 11 is fixed between the tops of the front and rear corresponding first support blocks 7. A second support member 12 is fixed to the top of the outer wall in the middle of the right side of the support frame 2, and a second electric push rod 13 is installed on the upper part of the second support member 12. A blocking frame 14 is fixed to the left side of the telescopic rod of the second electric push rod 13, and a slide groove is provided on the left side of the rear of the blocking frame 14, and a sliding plate 16 is slidably connected in the slide groove. Several springs 15 are connected between the slide groove on the front side of the rear of the blocking frame 14 and the sliding plate 16, and the blocking frame 14 is slidably connected to the right side of the right limit plate 11. The base 1 is made of insulating rubber and the front side of the support frame 2 is made of transparent glass.

[0022] like Figure 4 As shown, it also includes a second support block 17, a second rotating shaft 18, a second servo motor 19 and a second flat belt 20. Two second support blocks 17 are symmetrically fixed to the top of the front side of the support frame 2. The second rotating shaft 18 is rotatably connected between the front and rear corresponding support blocks. A second servo motor 19 is installed on the front side of the top of the support frame 2. The output shaft of the second servo motor 19 passes through the corresponding second support block 17 and is connected to the second rotating shaft 18 on the right. A second flat belt 20 is wrapped around the two second rotating shafts 18.

[0023] When workers need to automatically transport lithium iron phosphate batteries for voltage testing, they first start the first servo motor 9. The output shaft of the first servo motor 9 will drive the first rotating shaft 8 and the first flat belt 10 to rotate. Then the lithium iron phosphate battery is placed on the top and rear side of the first flat belt 10. The lithium iron phosphate battery will be transported forward on the first flat belt 10. When the lithium iron phosphate battery passes through the first flat belt 10, it will be transported to the second flat belt 20. Then the second electric push rod 13 is started. The second electric push rod 13 drives the blocking frame 14 to move to the left and the sliding plate 16 hits the lithium iron phosphate battery. At this time, the sliding plate 16 is squeezed into the sliding groove on the left side of the rear part of the blocking frame 14, and the several springs 15 are compressed. When the lithium iron phosphate battery stops contacting the sliding plate 16 during transportation, the several springs 15 stretch and push the sliding plate 16 to move to the left, and the sliding plate 16 will prevent the next lithium iron phosphate battery from continuing to move. When the lithium iron phosphate battery hits the front side of the blocking frame 14 during transportation, it will also stop moving and remain in the blocking frame 14. When the previous lithium iron phosphate battery is detected, the second electric push rod 13 is started to move backward, and the above steps are repeated again.

The third rotating shaft 23 is rotatably connected between the front and rear corresponding third support blocks 22. A third servo motor 24 is installed in the middle of the front side of the limit frame 21. The output shaft of the third servo motor 24 passes through the corresponding third support block 22 and is connected to the third rotating shaft 23 on the left. A third flat belt 25 is wound around the two third rotating shafts 23. The first flat belt 10, the second flat belt 20 and the third flat belt 25 are all made of insulating material.

[0025] When a worker needs to perform an automatic voltage test on a lithium iron phosphate battery, he first starts the two first electric push rods 5 and the second servo motor 19. At this time, the two first electric push rods 5 extend their telescopic rods to drive the two voltage detectors 6 to move backward. Then, the two voltage detectors 6 respectively contact the positive and negative electrodes of the lithium iron phosphate battery conveyed on the second flat belt 20 and perform a voltage test on the battery. The test results will be displayed on the voltage test meter 3. Then, the second servo motor 19 determines whether the battery is qualified based on the voltage test results of the battery. If it is qualified, the output shaft of the second servo motor 19 will drive the second rotating shaft 18 and the second flat belt 20. It rotates to the left and is transported to the top of the left third flat belt 25. If it is unqualified, the output shaft of the second servo motor 19 will drive the second rotating shaft 18 and the second flat belt 20 to rotate to the right and transport it to the top of the right third flat belt 25. Finally, the two third servo motors 24 are started. The left third servo motor 24 will drive the left third rotating shaft 23 and the left third flat belt 25 to rotate to the left and transport the lithium iron phosphate battery to the left. The right third servo motor 24 will drive the right third rotating shaft 23 and the right third flat belt 25 to rotate to the right and transport the lithium iron phosphate battery to the right. At this time, the voltage detection of the lithium iron phosphate battery is completed.
