Description

Technical Field

[0001] The invention belongs to the technical field of storage batteries, and in particular relates to an air tightness detection device for storage batteries. Background Art

[0002] The battery needs to be tested for air tightness during the assembly process. An inflation device is used to inflate and maintain the pressure for a period of time, and the pressure changes are observed to detect the air tightness.

[0003] For example, Chinese invention CN114739597A discloses an automatic battery air tightness detection device, which places the battery in a detection box, drives the inflation mechanism downward through a lifting mechanism to contact the top of the battery for inflation, and at the same time, the upper cover sealing mechanism contacts the detection box to seal the detection box, thereby ensuring that the battery is isolated from the outside world when inflated to detect air tightness.

[0004] However, during the operation, the battery needs to be placed in a test box, and needs to be taken out of the test box after the test is completed. Due to the influence of the side walls of the test box, it is very inconvenient to take and put the battery, resulting in poor overall convenience of use and affecting the overall test efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide an airtightness detection device for batteries. By arranging a pallet in the detection box and using a telescopic cylinder to drive the pallet to rise and fall, it is convenient to put the battery into or take it out of the detection box, thereby solving the problem that the existing batteries are inconvenient to take and put, resulting in poor convenience of use and affecting the overall detection efficiency.

[0010] As a preferred technical solution of the present invention, the push rod sleeve is provided with a spring, the lower end of the spring abuts against the connecting plate, and the upper end abuts against the support rod, so that when the sealing cover plate moves up, the spring pushes the push rod up, thereby pulling the push plate to move and reset through the push rod.

[0036] Embodiment 1

[0037] See also Figure 1 and 2 As shown, the present invention is an airtightness detection device for a battery, comprising a base 1, the base 1 is connected to a detection box 2 and a bracket plate 101 located above the detection box 2, the bracket plate 101 is fixedly connected to a telescopic device 102, the telescopic end of the telescopic device 102 is connected to a sealing cover plate 3 for sealing the upper port of the detection box 2, the sealing cover plate 3 can adopt the mechanism of the existing technology, and an inflation head and the like are connected to the sealing cover plate 3.

[0038] like Figure 3 and 7 As shown, a through hole 201 is opened on the bottom wall of the detection box 2, and the base 1 is connected to a telescopic cylinder 103 located below the detection box 2. The telescopic end of the telescopic cylinder 103 passes through the through hole 201 and is fixedly connected to a support plate 104 located inside the detection box 2. An annular sealing ring 105 is connected to the lower surface of the support plate 104 for achieving sealing between the support plate 104 and the bottom wall of the detection box 2.

[0039] like Fig. 9As shown, when the battery needs to be placed, the pallet 104 is lifted to the upper port position of the detection box 2 by the telescopic cylinder 103, so that the battery can be placed on the pallet 104, and then the pallet 104 is driven down by the telescopic cylinder 103, thereby driving the battery into the detection box 2, and the pallet 104 is sealed against the bottom wall of the detection box 2.

[0040] When the inspection is completed, the support plate 104 is lifted to the upper port position of the inspection box 2 by the telescopic cylinder 103, so that the battery is lifted out, which is convenient for taking out the battery. The telescopic cylinder 103 drives the support plate 104 to rise and fall, making it convenient for putting the battery in and taking it out of the inspection box 2, thereby improving the convenience of taking and placing the battery, which is beneficial to improving the overall convenience of use and the overall inspection efficiency.

[0041] Embodiment 2

[0042] like Figure 3 and 4 As shown, on the basis of the first embodiment, the inner walls of the detection box 2 are fixedly connected with connecting plates 202, and the top rod 4 is movably inserted through the connecting plates 202. The number of connecting plates 202 can be two, which are arranged up and down. By setting two, the connection stability of the top rod 4 is improved.

[0043] like Figure 5 As shown, the push rod 4 is fixedly connected to two axially distributed support rods 401, the support rods 401 are fixedly inserted through the push rod 4, and both ends of the two support rods 401 are rotatably connected to push rods 402, so that the push rod 4 is connected to a total of four push rods 402, and a push plate 5 is hinged through the four push rods 402, and the hinge points of the four push rods 402 and the push plate 5 are distributed in a rectangular shape, so that the force on the push plate 5 is more balanced.

[0044] like Figure 4 and 6 As shown, the support plate 104 is adapted to the test box 2, and is provided with an avoidance notch 106 corresponding to the position of the push plate 5, so that the push plate 5 has a certain amount of movement space. At the same time, the inner side walls of the test box 2 are all provided with outwardly protruding recessed portions 204, and the push rod 4 and the push plate 5 are both located in the recessed portions 204, so that the support plate 104 will not be affected by the push plate 5 when driving the battery to descend, ensuring the convenience of use.

[0045] like Figure 8 , 10As shown in 11, the lower surface of the push plate 5 is against the bottom wall of the detection box 2, and is used to press the push rod 4 through the sealing cover plate 3. The push rod 4 moves downward and pushes the push plate 5 toward the center of the detection box 2 through the push rod 402, so that the battery located on the support plate 104 is pushed by the push plate 5, and the battery is positioned by the push plate 5. The placement position of the battery is more accurate, so that the inflation head connected to the sealing cover plate 3 can be accurately aligned with the battery, thereby improving the accuracy of the detection.

[0046] Embodiment 3

[0047] On the basis of the second embodiment, the push rod 4 is provided with a spring 403, the lower end of the spring 403 is against the connecting plate 201, and the upper end is against the support rod 401, so that when the sealing cover plate 3 moves upward, the spring 403 pushes the push rod 4 to move upward, and the push plate 5 is pulled to move and reset through the push rod 402, so that the push plate 5 returns to the recessed portion 204, so that the overall convenience of use is further improved.

[0048] At the same time, two sleeves 203 are fixedly connected to the inner side walls of the detection box 2, and a guide rod 501 that cooperates with the sleeve 203 is fixedly connected to the side of the push plate 5. The two sleeves 203 connected to each inner side wall of the detection box 2 are symmetrically arranged relative to the push rod 4. The guide rod 501 cooperates with the sleeve 203 to support and guide the push plate 5 when it moves, thereby greatly improving the stability of the push plate 5 when it moves.

[0049] In addition, a buffer block 404 is fixedly connected to the upper end of the push rod 4, and a rubber top block 301 is fixedly connected to the lower surface of the sealing cover plate 3. The rubber top block 301 presses down the buffer block 404 to press the guide rod 4 downward. The buffering and deformation effects of the buffer block 404 and the rubber top block 301 can reduce the impact on the guide rod 4. The deformation of the buffer block 404 and the rubber top block 301 can also prevent the push plate 5 from squeezing the battery with excessive force, thereby ensuring the overall reliability of use.
