Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery detection, in particular to a lithium battery power detection device. Background Art

[0002] With the development of science and technology, lithium batteries have become the mainstream. Lithium batteries have the advantages of extremely low self-discharge rate and gentle discharge voltage. Lithium batteries generally have a nominal voltage higher than 3.0 volts, making them more suitable for use as integrated circuit power supplies. During production, existing lithium batteries are usually tested for power after being used for a period of time to test the durability of the battery.

[0003] For example, the patent specification of an existing Chinese patent (publication number: CN216718622U) discloses a device for detecting the power level of a lithium battery. The device for detecting the power level of a lithium battery is provided with a driving motor, which can drive the screw to rotate, and under the action of the slide groove, drive the connecting plate to move, thereby driving the second placement block to move, and no manual push is required. The operation is simple and easy to use; a positioning sleeve is provided on the second placement block, and under the action of the positioning rod, the movable block can be positioned to avoid its displacement during movement, which can effectively prevent the problem of large errors in lithium battery detection.

[0004] However, in the implementation of relevant technologies, it was found that the device for detecting the power level of a lithium battery designed above has the following problems: although the device for detecting the power level of a lithium battery can electrically detect and position the battery, it cannot electrically push the battery into or out of the detection slot when the battery is placed on the detection device, so personnel need to manually carry it. Since batteries are generally heavy, manual transportation is undoubtedly time-consuming and labor-intensive, and manual operations are still relatively large. In view of this, a lithium battery power detection device is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a lithium battery power detection device.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a lithium battery power detection device, comprising a detection frame, a detection groove is provided on the front side of the detection frame, a driving member is installed in the detection groove, and a pushing member is provided at the other end of the driving member, which is used to drive the pushing member to pull the battery to be detected into the detection groove, a negative pressure groove is provided on one side of the pushing member, an air pump is fixedly installed on the top of the pushing member, and an intake pipe is provided at the other end of the air pump, and the other end of the intake pipe is fixedly inserted into the top of the pushing member and extends into the negative pressure groove.

[0007] As a further description of the above technical solution: a sealing ring is fixedly installed on the front side of the push member, and the material of the sealing ring is fluororubber. Since fluororubber has certain elasticity and high temperature resistance, it can seal the negative pressure tank and the battery while allowing the sealing ring to be used normally in a high temperature environment.

[0008] As a further description of the above technical solution: an exhaust pipe is fixedly connected to one side of the pusher, and a valve is provided on the exhaust pipe. When the valve is opened, external air can be introduced into the negative pressure tank, thereby releasing the limit on the battery and making it easier for people to transport the battery.

[0009] As a further description of the above technical solution: the driving member includes an electric push rod, which is installed in the detection groove, and the driving end of the electric push rod is fixedly connected to the rear side of the pushing member.

[0010] As a further description of the above technical solution: a fixing part is provided in the detection frame, a mounting groove is provided on the top of the fixing part, a rotating shaft is rotatably provided in the mounting groove, and a roller is fixedly sleeved on the rotating shaft. When the battery is pulled from the transport vehicle into the detection groove, the battery will drive the roller to rotate on the roller, which can reduce the friction of the battery sliding in the detection groove, which not only reduces the output power of the electric push rod and saves electric energy, but also avoids damage to the battery surface due to excessive friction.

[0011] As a further description of the above technical solution: there are multiple mounting slots, and the multiple mounting slots are opened at equal intervals on the top of the fixing member. The cooperation of the multiple mounting slots can make the battery more stable when sliding.

[0012] As a further description of the above technical solution: a plurality of damping cylinders and a first spring are fixedly installed on the bottom of the fixing member, and the other ends of the damping cylinder and the first spring are fixedly installed on the bottom wall of the detection frame, the fixing member is slidably inserted in the detection frame, a sliding hole is provided in the detection groove, a slider is slidably connected in the sliding hole, the slider is fixedly connected to the electric push rod, a second spring is installed on the top of the slider, and the other end of the second spring is set in the sliding hole. At the moment the battery is pulled into the detection groove from the transport vehicle, the battery will instantly press the detection groove due to its heavy mass. At this time, the battery drives the fixing member to compress the first spring, and at the same time the electric push rod drives the slider to stretch the second spring and slide downward in the sliding hole. After the pressure is absorbed, the damping cylinder is finally cooperated to make the first spring slowly rebound, which can achieve the effect of buffering the roller, help solve the problem of the roller being crushed by the battery, and thus help extend the service life of the roller.

[0013] As a further description of the above technical solution: a display screen is installed on one side of the detection frame, which is used to electrically connect to the device for detecting the battery power, and can conveniently amplify the data for easy observation by personnel.

[0014] The utility model has the following beneficial effects:

[0015] The lithium battery power detection device designed by the utility model turns on the electric push rod, so that the driving end of the electric push rod extends to drive the push piece to move until the push piece is in contact with one side of the battery. Since the surface of the battery is usually smooth, the negative pressure groove and one side of the battery are tightly in contact at this time. Then the air pump is turned on to draw the air between the negative pressure groove and the battery through the suction pipe and discharge it to the outside. At this time, negative pressure is generated in the negative pressure groove. Then the electric push rod is turned on to shorten the driving end of the electric push rod, so that the battery can be drawn into the detection groove, which can achieve the effect of automatic loading. According to the above principle, the effect of automatic unloading can also be achieved. The manual participation of personnel is relatively small in the whole process, which reduces the workload of personnel.

[0016] The lithium battery power detection device designed in this utility model drives the roller to rotate when the battery is pulled from the transport vehicle into the detection tank, thereby reducing the friction of the battery sliding in the detection tank. This not only reduces the output power of the electric push rod and saves electricity, but also avoids damage to the battery surface due to excessive friction.

[0017] The lithium battery power detection device designed in the utility model has the following advantages: when the battery is pulled from the transport vehicle into the detection tank, the battery will instantly press the detection tank due to its heavy mass. At this time, the battery drives the fixing part to compress the first spring, and at the same time the electric push rod drives the slider to stretch the second spring and slide downward in the slide hole. After the pressure is completely absorbed, the damping cylinder is finally used to slowly rebound the first spring, which can achieve the effect of buffering the roller, help solve the problem of the roller being damaged by the battery, and thus help extend the service life of the roller.

[0024] Reference Figure 1-4 The utility model provides a lithium battery power detection device: it includes a detection frame 1, a detection slot 2 is opened on the front side of the detection frame 1, a driving member is installed in the detection slot 2, and a pushing member 4 is provided at the other end of the driving member, which is used to drive the pushing member 4 to pull the battery to be detected into the detection slot 2, and a negative pressure slot 5 is opened on one side of the pushing member 4. An air pump 6 is fixedly installed on the top of the pushing member 4, and an air suction pipe 7 is provided at the other end of the air pump 6. The other end of the air suction pipe 7 is fixedly inserted into the top of the pushing member 4 and extends into the negative pressure slot 5. The driving member includes an electric push rod 3, the electric push rod 3 is installed in the detection slot 2, and the driving end of the electric push rod 3 is fixedly connected to the rear side of the pushing member 4.

[0025] During the specific implementation, the vehicle body equipped with the battery is pushed to the front side of the detection tank 2, and then the electric push rod 3 is turned on, so that the driving end of the electric push rod 3 is extended to drive the push piece 4 to move until the push piece 4 is against one side of the battery. Since the surface of the battery is usually smooth, the negative pressure tank 5 is tightly against one side of the battery at this time, and then the air pump 6 is turned on to make the air pump 6 extract the air between the negative pressure tank 5 and the battery through the suction pipe 7 and discharge it to the outside. At this time, negative pressure will be generated in the negative pressure tank 5, and then the electric push rod 3 is turned on to shorten the driving end of the electric push rod 3, so that the battery can be drawn into the detection tank 2, which can achieve the effect of automatic loading. According to the above principle, the effect of automatic unloading can also be achieved. During the whole process, there is less manual participation of personnel, which reduces the work intensity of personnel, and then the personnel can test the battery power.

[0026] As a further embodiment of the above technical solution, a sealing ring 8 is fixedly mounted on the front side of the pusher 4. The sealing ring 8 is made of fluororubber. Due to its elasticity and high temperature resistance, fluororubber can seal the negative pressure tank 5 and the battery while ensuring normal use in high temperature environments.

[0027] As a further implementation scheme of the above technical solution: an exhaust pipe 9 is fixedly connected to one side of the pusher 4, and a valve 10 is provided on the exhaust pipe 9. When the valve 10 is opened, the outside air can be introduced into the negative pressure tank 5, thereby releasing the restriction on the battery and facilitating the transportation of the battery.

[0028] It should be noted that the detection frame 1 also needs to be equipped with a device for detecting the battery power, which is usually equipped with a circuit and a power detector. The power detector is connected to the battery through the circuit and can read the remaining power of the battery. Since the battery power detection equipment belongs to the existing technology, it will not be explained in detail in this manual.

[0029] As a further implementation of the above technical solution: a fixing member 11 is provided within the detection frame 1, and a mounting slot 14 is provided at the top of the fixing member 11. A rotating shaft 12 is rotatably provided within the mounting slot 14, and a roller 13 is fixedly sleeved on the rotating shaft 12. When the battery is pulled from the transport vehicle into the detection tank 2, the battery drives the roller 13 to rotate on the roller 13, which can reduce the friction of the battery sliding in the detection tank 2. This not only reduces the output power of the electric push rod 3 and saves electricity, but also prevents damage to the battery surface due to excessive friction.

[0030] As a further implementation of the above technical solution: there are multiple mounting grooves 14, and multiple mounting grooves 14 are evenly spaced and opened on the top of the fixing member 11. The cooperation of multiple mounting grooves 14 can make the battery more stable when sliding.

[0031] As a further implementation of the above technical solution: a plurality of damping cylinders 15 and a first spring 16 are fixedly mounted on the bottom of the fixing member 11. The other ends of the damping cylinders 15 and the first spring 16 are fixedly mounted on the bottom wall of the detection frame 1. The fixing member 11 is slidably inserted into the detection frame 1. A sliding hole 18 is formed in the detection slot 2. A slider 19 is slidably connected to the sliding hole 18. The slider 19 is fixedly connected to the electric push rod 3. A second spring 20 is mounted on the top of the slider 19. The other end of the second spring 20 is set in the sliding hole 18. When the battery is pulled from the transport vehicle into the detection slot 2, the battery, due to its heavy mass, will instantly press the detection slot 2. At this time, the battery drives the fixing member 11 to compress the first spring 16. At the same time, the electric push rod 3 drives the slider 19 to stretch the second spring 20 and slide downward in the sliding hole 18. After the pressure is completely absorbed, the damping cylinder 15 is finally used to slowly rebound the first spring 16. This can achieve a buffering effect on the roller 13, helping to solve the problem of the roller 13 being damaged by the battery, thereby helping to extend the service life of the roller 13.

[0032] As a further implementation scheme of the above technical solution: a display screen 17 is installed on one side of the detection frame 1, which is used to electrically connect to the device for detecting the battery power, and can conveniently amplify the data for convenient observation by personnel.

[0033] Working principle:

[0034] When using the utility model, first, all the electrical appliances involved in the inside and outside of the detection frame 1 are connected to the external power supply. Then, when it is necessary to test the power of the battery to be tested, first push the car body with the battery to the front side of the detection tank 2, then turn on the electric push rod 3, so that the driving end of the electric push rod 3 extends to drive the push piece 4 to move until the push piece 4 is against one side of the battery. Since the surface of the battery is usually smooth, the negative pressure tank 5 is tightly against one side of the battery at this time, and then turn on the air pump 6 to make the air pump 6 extract the air between the negative pressure tank 5 and the battery through the suction pipe 7 and discharge it to the outside. At this time, negative pressure will be generated in the negative pressure tank 5, and then turn on the electric push rod 3 to shorten the driving end of the electric push rod 3, so that the battery can be drawn into the detection tank 2, which can achieve the effect of automatic loading. According to the above principle, the effect of automatic unloading can also be achieved. In the whole process, there is less manual participation of personnel, which reduces the work intensity of personnel, and then personnel can test the power of the battery;

[0035] In addition, in the process of the battery being pulled from the transport vehicle into the detection tank 2, the battery will drive the roller 13 to rotate on the roller 13, which can reduce the friction of the battery sliding in the detection tank 2, not only reducing the output power of the electric push rod 3 and saving electric energy, but also avoiding damage to the battery surface due to excessive friction. It should be noted that at the moment the battery is pulled from the transport vehicle into the detection tank 2, the battery will instantly press on the detection tank 2 due to its heavy mass. At this time, the battery drives the fixing part 11 to compress the first spring 16, and at the same time the electric push rod 3 drives the slider 19 to stretch the second spring 20 and slide downward in the slide hole 18. After the pressure is absorbed, the damping cylinder 15 is finally cooperated to make the first spring 16 slowly rebound, which can achieve the effect of buffering the roller 13, help solve the problem of the roller 13 being crushed by the battery, thereby helping to extend the service life of the roller 13.
