Description

Technical Field

[0001] This utility model relates to the field of storage battery technology, specifically to a lead-acid battery sealing test device. Background Technology

[0002] Lead-acid batteries are primarily made of lead and its oxides as electrodes, and their electrolyte is a sulfuric acid solution. Although lead-acid batteries have lower energy and shorter deep-cycle life compared to lithium batteries and nickel-metal hydride batteries, they remain one of the world's most produced and widely used power sources due to their advantages such as low self-discharge, superior high and low temperature performance, mature production and recycling technologies, and low price. Lead-acid batteries are mostly used in tractors, tricycles, and car starters.

[0004] However, when using the above-mentioned device, the staff not only need to manually place the battery to be tested for air tightness on the top of the connecting plate, but also need to manually twist the threaded rods on both sides to fix it. This series of operations is not only tedious and complicated, but also significantly reduces work efficiency when dealing with a large number of batteries to be tested. Utility Model Content

This technical solution solves the problem mentioned in the background art that when using the above-mentioned device, the operator not only needs to manually place the battery to be tested on the top of the connecting plate, but also needs to manually twist the threaded rods on both sides for fixation. This series of operations is not only cumbersome and complicated, but also significantly reduces work efficiency when dealing with a large number of batteries to be tested.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A lead-acid battery sealing test device includes a base plate and a conveying device. The conveying device is fixedly installed on the top of the base plate. The conveying device includes a housing, with support legs fixedly installed on both the left and right sides of the bottom of the housing. Two sets of conveyor belts are arranged inside the housing, and the top of the two sets of conveyor belts is movably connected to the component to be tested. A stepper motor is fixedly installed on the front side of the housing, and an infrared detector is fixedly installed on the top of the housing. A cylinder is fixedly installed on the top of the base plate, and a top plate is fixedly connected to the extension end of the cylinder. The top plate is positioned between the two sets of conveyor belts, and two sets of fixing plates are fixedly connected to the top of the top plate. A clamping mechanism is provided between the two sets of fixing plates. A fixing frame is also fixedly connected to the top of the base plate, and a lifting mechanism is arranged inside the fixing frame. An airtightness detector is fixedly installed on the top of the lifting mechanism.

[0008] Preferably, the clamping mechanism includes a double-ended lead screw rotatably connected between two sets of fixed plates. A drive motor is fixedly installed on the outer side of one set of fixed plates. The output end of the drive motor extends between the two sets of fixed plates and is fixedly connected to one end of the double-ended lead screw. Two sets of fixed rods are also fixedly connected between the two sets of fixed plates. The two sets of fixed rods are symmetrically distributed on the front and rear sides of the double-ended lead screw. Moving plates are threadedly connected to the left and right sides of the outer circumference of the double-ended lead screw. The moving plates on both sides slide on the outer circumference of the two sets of fixed rods, and a placement plate is fixedly connected to the side of the moving plates that are close to each other.

[0009] Preferably, the lifting mechanism includes a second drive motor fixedly installed on the top of the fixed frame. A threaded rod is rotatably connected inside the fixed frame. The output end of the second drive motor extends into the interior of the fixed frame and is fixedly connected to one end of the threaded rod. Two sets of sliding rods are also fixedly connected inside the fixed frame. The two sets of sliding rods are symmetrically distributed on the left and right sides of the threaded rod. A movable plate is threadedly connected to the outer circumferential surface of the threaded rod. The movable plate is slidably connected to the two sets of sliding rods. A load-bearing plate is fixedly connected to the side of the movable plate away from the threaded rod. The airtightness detector is fixedly installed on the top of the load-bearing plate.

[0010] Preferably, a mounting plate is fixedly connected to the top of the outer shell, and a second cylinder is fixedly installed on the outer side of the mounting plate. The extension end of the second cylinder passes through the mounting plate and is fixedly connected to a push plate.

[0012] Preferably, the top of the test piece is provided with a connection port, the output end of the airtight detector extends to the lower side of the load plate and is connected to an inflation tube, and the outer diameter of the inflation tube is adapted to the inner diameter of the connection port.

[0013] Preferably, the bottom of the load-bearing plate is provided with a sealing groove that matches the connection port.

[0014] Compared with the prior art, this utility model provides a lead-acid battery sealing performance testing device, which has the following advantages:

[0015] This invention uses a stepper motor to automatically transport the battery to the testing area. After the infrared detector accurately locates the battery, a cylinder drives the top plate to rise. Simultaneously, the clamping mechanism, driven by a motor, drives a double-ended lead screw to clamp the battery, ensuring its stability during testing. Subsequently, the lifting mechanism's motor rotates the threaded rod, causing the airtightness detector to accurately descend to the battery connection port. Gas is injected through the inflation tube for a sealing test. After the test, the clamping mechanism releases, and the cylinder returns the battery to the conveyor belt. If the battery fails to meet the sealing requirements, a cylinder-driven pusher plate pushes it into the sorting hopper when the battery reaches the sorting area. Qualified batteries continue to the next process. This not only avoids the tedious manual sorting but also improves testing efficiency. Attached Figure Description

[0032] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0033] Please refer to Figures 1 to 5 As shown, a lead-acid battery sealing test device includes a base plate 1 and a conveying device 2. The conveying device 2 is fixedly installed on the top of the base plate 1. The conveying device 2 includes a housing 201. Support legs 202 are fixedly installed on both the left and right sides of the bottom of the housing 201. Two sets of conveyor belts 203 are arranged inside the housing 201. The top of the two sets of conveyor belts 203 is movably connected to the part to be tested 3. A stepper motor 204 is fixedly installed on the front side of the housing 201. An infrared detector 4 is fixedly installed on the top of the housing 201. A cylinder 5 is fixedly installed on the top of the base plate 1. The extension end of the cylinder 5 is fixedly connected to a top plate 6. The top plate 6 is located between the two sets of conveyor belts 203. Two sets of fixing plates 7 are fixedly connected to the top of the top plate 6. A clamping mechanism 8 is provided between the two sets of fixed plates 7. The clamping mechanism 8 includes a double-ended lead screw 801 rotatably connected between the two sets of fixed plates 7. A drive motor 802 is fixedly installed on the outer side of one set of fixed plates 7. The output end of the drive motor 802 extends between the two sets of fixed plates 7 and is fixedly connected to one end of the double-ended lead screw 801. Two sets of fixed rods 803 are also fixedly connected between the two sets of fixed plates 7. The two sets of fixed rods 803 are symmetrically distributed on the front and rear sides of the double-ended lead screw 801. Moving plates 804 are threadedly connected to the left and right sides of the outer circumference of the double-ended lead screw 801. The moving plates 804 slide on the outer circumference of the two sets of fixed rods 803. A placement plate 805 is fixedly connected to the side of the moving plates 804 that is close to each other.

[0034] In this scheme, the test piece 3 is first placed on top of two sets of conveyor belts 203, and the stepper motor 204 is turned on. The stepper motor 204 drives the two sets of conveyor belts 203 to move the test piece 3 from right to left. When the infrared detector 4 detects that the test piece 3 has reached above the top plate 6, the stepper motor 204 stops driving the conveyor belts 203. Then, the cylinder 5 is turned on. The cylinder 5 uses the top plate 6 to make the test piece 3 detach from the two sets of conveyor belts 203 and make it rise. At the same time, the drive motor 802 is turned on. The drive motor 802 drives the double-headed lead screw 801 to rotate, and then the moving plate 804 is brought closer to each other through the two sets of fixing rods 803. Thus, during the rising of the top plate 6, the test piece 3 is effectively fixed inside the angle between the two sides of the placement plate 805 and the moving plate 804, avoiding the problem of test failure due to displacement of the test piece 3 when performing airtightness testing.

[0035] A fixed frame 9 is also fixedly connected to the top of the base plate 1. A lifting mechanism 10 is installed inside the fixed frame 9. An airtightness detector 11 is fixedly installed on the top of the lifting mechanism 10. The lifting mechanism 10 includes a second drive motor 1001 fixedly installed on the top of the fixed frame 9. A threaded rod 1002 is rotatably connected inside the fixed frame 9. The output end of the second drive motor 1001 extends into the interior of the fixed frame 9 and is fixedly connected to one end of the threaded rod 1002. Two sets of sliding rods 1003 are also fixedly connected inside the fixed frame 9. The two sets of sliding rods 1003 are symmetrically distributed on the left and right sides of the threaded rod 1002. The outer peripheral surface of the device is threaded with a movable plate 1004, which is slidably connected to two sets of slide rods 1003. A load plate 1005 is fixedly connected to the side of the movable plate 1004 away from the threaded rod 1002. An airtight detector 11 is fixedly installed on the top of the load plate 1005. A connection port 301 is provided on the top of the device to be tested 3. The output end of the airtight detector 11 extends to the lower side of the load plate 1005 and is connected to an inflation pipe 1101. The outer diameter of the inflation pipe 1101 is adapted to the inner diameter of the connection port 301. A sealing groove 1006 adapted to the connection port 301 is provided at the bottom of the load plate 1005.

[0036] In this scheme, after the test piece 3 is detached from the two sets of conveyor belts 203 and effectively fixed, the second drive motor 1001 is turned on. The second drive motor 1001 drives the threaded rod 1002 to rotate. Guided by the two sets of slide rods 1003, the movable plate 1004 is lowered. Then, the load plate 1005 drives the air tightness detector 11 to lower, so that the inflation pipe 1101 enters the interior of the connection port 301 and the connection port 301 is locked into the interior of the sealing groove 1006, thereby preventing air leakage at the connection between the connection port 301 and the inflation pipe 1101. Then, the air tightness detector 11 is turned on, so that the gas generated by it enters the interior of the test piece 3 through the inflation pipe 1101 and the connection port 301. The gas entering the interior of the test piece 3 is detected in real time, so as to judge the sealing effect of the test piece 3 by whether the air pressure inside the test piece 3 drops.

[0037] A mounting plate 12 is fixedly connected to the top of the outer casing 201. A cylinder 13 is fixedly installed on the outside of the mounting plate 12. The extended end of the cylinder 13 passes through the mounting plate 12 and is fixedly connected to a push plate 14. A diversion hopper 15 is provided on the front side of the outer casing 201 to cooperate with the push plate 14.

[0038] In this scheme, after the test piece 3 is tested, it is placed back on top of the two sets of conveyor belts 203 by cylinder 5 and clamping mechanism 8. When the air tightness of the test piece 3 does not meet the requirements, and the test piece 3 reaches the front of the push plate 14 through the two sets of conveyor belts 203, cylinder 13 is activated. Cylinder 13 drives the push plate 14 to push the test piece 3 with insufficient air tightness into the diversion hopper 15. Conversely, when the air tightness of the test piece 3 meets the requirements, it can enter the next process through the two sets of conveyor belts 203. This avoids the problem of manually classifying the test piece 3 and further improves the practicality and applicability of this device.

[0039] The working principle and usage process of this device are as follows: First, the part to be tested 3 is placed on top of the two sets of conveyor belts 203, and the stepper motor 204 is turned on. The stepper motor 204 drives the two sets of conveyor belts 203 to move the part to be tested 3 from right to left. When the infrared detector 4 detects that the part to be tested 3 has reached the top plate 6, the stepper motor 204 stops driving the conveyor belts 203. Then, the cylinder 5 is turned on. The cylinder 5 uses the top plate 6 to make the part to be tested 3 detach from the two sets of conveyor belts 203 and make it rise. At the same time, the drive motor 802 is turned on. The drive motor 802 drives the double-headed lead screw 801 to rotate, and then the moving plate 804 is brought closer to each other through the two sets of fixed rods 803. Thus, during the rising process of the top plate 6, the part to be tested 3 is effectively fixed inside the angle between the two sides of the placement plate 805 and the moving plate 804, avoiding the problem of failure of the test due to the displacement of the part to be tested 3 when performing airtightness test.

[0040] After the test piece 3 is detached from the two sets of conveyor belts 203 and effectively fixed, the second drive motor 1001 is turned on. The second drive motor 1001 drives the threaded rod 1002 to rotate. Guided by the two sets of slide rods 1003, the movable plate 1004 is lowered. Then, the load plate 1005 drives the air tightness detector 11 to lower, so that the inflation pipe 1101 enters the interior of the connection port 301 and the connection port 301 is locked into the interior of the sealing groove 1006, thereby preventing air leakage at the connection between the connection port 301 and the inflation pipe 1101. Then, the air tightness detector 11 is turned on, so that the gas generated by it enters the interior of the test piece 3 through the inflation pipe 1101 and the connection port 301. The gas entering the interior of the test piece 3 is detected in real time, so as to judge the sealing effect of the test piece 3 by whether the air pressure inside the test piece 3 drops.

[0041] After the test piece 3 is inspected, it is placed back on top of the two sets of conveyor belts 203 by cylinder 5 and clamping mechanism 8. When the air tightness of the test piece 3 does not meet the requirements, and the test piece 3 reaches the front of the push plate 14 through the two sets of conveyor belts 203, cylinder 13 is activated. Cylinder 13 drives the push plate 14 to push the test piece 3 with insufficient air tightness into the diversion hopper 15. Conversely, when the air tightness of the test piece 3 meets the requirements, it can enter the next process through the two sets of conveyor belts 203. This avoids the problem of manually classifying the test piece 3 and further improves the practicality and applicability of the device.
