Description

Technical Field

[0001] The utility model relates to the technical field of sealing test, in particular to a sealing water detection device. Background Art

[0002] Currently, batteries mainly include a shell, a cell, and a top cover, where the cell is housed in the shell. Figure 1 The top cover specifically includes a cover body 10 and two poles 20 arranged on the cover body 10. The cover body 10 is used to seal the opening of the shell. The two poles 20 are connected to the internal battery cells, and the two poles 20 are sealed and connected to the cover body 10 by extruding an insulating member 30 to prevent the electrolyte inside the shell from leaking outward from the gap between the pole 20 and the cover body 10, and also prevent external liquid from flowing into the shell from the gap between the pole 20 and the cover body 10.

[0003] Currently, the seal between the pole and the cover plate is mostly tested using water testing. Existing tooling for water testing consists of an upper and lower mold. During testing, the pole of the top cover is placed between the upper and lower molds. The upper and lower molds are then secured with multiple screws, sealing the connection between the pole and the cover plate within the upper and lower molds. Gas is then introduced into the upper or lower mold, and the test location on the top cover is immersed in water to observe for bubbles. If bubbles are present, the seal between the pole and the cover plate is faulty. If no bubbles are present, the seal between the pole and the cover plate is good. With existing tooling, operators must loosen the screws between the upper and lower molds each time they use the tooling before inserting the top cover between them and tightening the screws again. This cumbersome operation can easily fatigue operators and lead to low work efficiency.

[0004] Therefore, there is a need to improve the existing technology. Utility Model Content

[0005] The utility model provides a sealing water detection device, which mainly solves the technical problem in the prior art that the water detection efficiency is low because the operators need to loosen or tighten the screws between the upper die and the lower die multiple times.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A water-tightness inspection device comprises a frame, a support base, a water cylinder, a driving mechanism and at least one upper die assembly;

[0008] The support base is connected to the frame and is used to carry the object to be tested. The upper mold assembly is located above the support base. The water cylinder is located below the support base in the initial position. The water cylinder is provided with a water tank that is open upward and used to contain liquid.

[0009] The upper mold assembly includes a connected driver and an upper mold, a sealing ring is provided at the bottom of the upper mold or the top of the support seat, the inner diameter of the sealing ring is larger than the outer dimensions of the test position of the test object at the top, the driver is used to drive the upper mold to move up and down, the upper mold and the support seat are used to jointly clamp the sealing ring, and an air intake channel is provided in the upper mold, one end of which leads to the inner area of ​​the sealing ring;

[0010] The driving mechanism is connected to the frame and the water cylinder, and is used for driving the water cylinder to move up and down.

[0011] In one of the technical solutions, the frame includes a box body, multiple vertical plates fixed on the top of the box body, and a large plate fixed to the multiple vertical plates respectively. The driving mechanism is fixed inside the box body, and the driver is fixed on the side of the large plate facing away from the vertical plates.

[0012] In one of the technical solutions, the driving mechanism and the driver are both cylinders, and a control panel and a solenoid valve electrically connected to each other are fixed inside the box. The solenoid valve is used to control the gas entering the driving mechanism, the driver or the air intake channel.

[0013] In one of the technical solutions, the sealing water inspection device includes two upper mold assemblies, and the support seat is arranged below the two upper mold assemblies. The position of at least one of the upper mold assemblies and at least one of the support seats on the frame is adjustable in the horizontal direction.

[0014] In one of the technical solutions, a movable plate is connected between one of the upper mold assemblies and the frame, and the position of the movable plate on the frame is adjustable in the horizontal direction. One of the upper mold assemblies and one of the support seats are fixed on the frame, and the other upper mold assembly and the other support seat are fixed on the movable plate.

[0015] In one of the technical solutions, a penetrating adjustment hole is provided on the movable plate, and the length of the adjustment hole extends in the horizontal direction.

[0016] In one of the technical solutions, a first slide groove is provided on the frame, and a second slide groove is provided at the bottom end of the movable plate. The first slide groove and the second slide groove both extend in the horizontal direction. One of the support seats is inserted into the first slide groove, and the other support seat is inserted into the second slide groove.

[0017] In one of the technical solutions, scale lines are provided on the top of the movable plate, and the scale lines are arranged at intervals in the horizontal direction.

[0018] In one of the technical solutions, the object to be tested is a battery top cover, which includes a cover body and two poles respectively sealed with the cover body. The position to be tested is the connection between the cover body and the poles. One of the support seats is used to support one end of the cover body in the length direction, and the other support seat is used to support the other end of the cover body in the length direction.

[0019] In one of the technical solutions, the sealing ring is arranged at the bottom of the upper mold, and one end of the air inlet channel passes through the bottom of the upper mold in the inner area of ​​the sealing ring.

[0020] Compared with the prior art, the sealing water detection device provided by the present invention has at least the following beneficial effects:

[0021] The bottom of the tested position of the object to be tested can be immersed in the liquid inside the water tank.

[0022] During operation, the operator only needs to place the top cover on the support seat, then start the driver and make the upper mold compress the sealing ring together with the support seat under the drive of the driver, so that the sealing ring is arranged around the outer periphery of the pole to seal the position to be tested between the pole and the cover body. At the same time, gas can be pre-introduced into the air inlet channel of the upper mold, and then the driving mechanism drives the water cylinder to rise. When the water cylinder rises into place, the position to be tested on the top cover will be immersed in the liquid in the water tank. At this time, you can observe whether bubbles are generated in the water tank. If bubbles are generated, it means that the seal between the pole on the top cover and the cover body is poor. If there are no bubbles, it means that the seal between the pole on the top cover and the cover body is good. After the test is completed, the control driving mechanism and the driver are reset.

[0023] As can be seen from the above paragraph, when using this solution, the main action of the operator is to place the top cover on the support seat or remove it from the support seat. The operation does not require multiple installation and removal of the upper mold and the support seat with screws. Therefore, the operating difficulty of the operator can be greatly reduced, thereby greatly improving the water inspection efficiency of the top cover sealing test. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Please also refer to Figures 2 to 4 An embodiment of the utility model provides a sealing water detection device, including a frame 1, a support base 2, a water cylinder 3, a driving mechanism 4 and at least one upper mold assembly 5.

[0038] Among them, the support base 2 is fixed on the frame 1 and is used to support the object to be tested (such as the top cover of the battery), the upper mold assembly 5 is located above the support base 2, and the water cylinder 3 is located below the support base 2 in the initial position. The water cylinder 3 is provided with a water tank 31 that is open upward and used to hold liquid.

[0039] The upper mold assembly 5 specifically includes a connected driver 51 and an upper mold 52. The driver 51 is fixed to the frame 1. A sealing ring 53 is provided at the bottom of the upper mold 52 (a sealing ring 53 can also be provided on the top of the support base 2). The inner diameter of the sealing ring 53 needs to be larger than the external dimensions of the test position of the object to be tested at the top (for example, when the object to be tested is a battery top cover, the inner diameter of the sealing ring 53 needs to be larger than the external dimensions of the top of the terminal 20 when it is placed on the support base 2). The driver 51 is used to drive the upper mold 52 to move up and down in the vertical direction. An air inlet channel 521 is provided in the upper mold 52. One end of the air inlet channel 521 is used to allow air to enter, and the other end of the air inlet channel 521 passes through the upper mold 52 in the internal area of ​​the sealing ring 53, so that gas can flow along the air inlet channel 521 to the test position. The driving mechanism 4 connects the frame 1 and the water cylinder 3, and the driving mechanism 4 is used to drive the water cylinder 3 to move up and down.

[0040] Specifically, during operation, the operator only needs to place the top cover on the support base 2, then start the driver 51 and make the upper mold 52 compress the sealing ring 53 together with the support base 2 under the drive of the driver 51, so that the sealing ring 53 is arranged around the outer periphery of the pole 20 to seal the connection between the pole 20 and the cover body 10. At the same time, gas can be pre-introduced into the air inlet channel 521 of the upper mold 52, and then the driving mechanism 4 drives the water cylinder 3 to rise. When the water cylinder 3 rises to its position, the position to be tested on the top cover (i.e., the connection between the cover body 10 and the pole 20) will be immersed in the liquid in the water tank 31. At this time, it can be observed whether bubbles are generated in the water tank 31. If bubbles are generated, it means that the seal between the pole 20 on the top cover and the cover body 10 is poor. If no bubbles are generated, it means that the seal between the pole 20 on the top cover and the cover body 10 is good. After the test is completed, the driving mechanism 4 is controlled to reset downward and the driver 51 is controlled to reset upward. At this time, the operator can remove the tested top cover from the support base 2.

[0041] As can be seen from the above paragraph, when using this solution, the main action of the operator is to place the top cover on the support seat 2 or remove it from the support seat 2. The operation does not require multiple assembly and disassembly of the upper mold 52 and the support seat 2 by screws. Therefore, the operating difficulty of the operator can be greatly reduced, thereby greatly improving the water inspection efficiency of the top cover sealing test.

[0042] In this embodiment, the rack 1 specifically includes a housing 11, multiple vertical panels 12 fixed to the top of the housing 11, and a large plate 13 respectively fixed to the multiple vertical panels 12. The drive mechanism 4 is fixed inside the housing 11 to protect the drive mechanism 4 from dust and increase its service life. The driver 51 is fixed to the side of the large plate 13 facing away from the vertical panels 12. This split-connection structure of the rack 1 has the advantages of simple and reliable structure, low processing cost, and easy assembly.

[0043] In this embodiment, the driving mechanism 4 and the driver 51 are preferably cylinders. A control board 14 and a solenoid valve 15 that are electrically connected to each other can be fixed inside the box 11. The control board 14 can control the opening or closing of the solenoid valve 15. The solenoid valve 15 is used to control the gas to enter the driving mechanism 4, the driver 51 or the air intake channel 521 to achieve the purpose of pneumatically controlling each actuator. The pneumatic control method has the advantage of lower cost.

[0044] In this embodiment, the sealing water inspection device preferably includes two upper mold assemblies 5, and a support base 2 is provided below each of the two upper mold assemblies 5, and the positions of at least one upper mold assembly 5 and at least one support base 2 on the frame 1 are adjustable in the horizontal direction. Through such a design, two objects to be tested can be subjected to water inspection tests at the same time, or two different positions on the same object to be tested (such as the positions corresponding to two poles on the same top cover) can be subjected to water inspection tests at the same time, thereby helping to further improve the efficiency of the water inspection test of the top cover. In addition, since the positions of at least one upper mold assembly 5 and at least one support base 2 on the frame 1 are adjustable in the horizontal direction, the two upper mold assemblies 5 and the two support bases 2 can be compatible with water inspection test operations with different lengths and distances between the two positions to be tested, so as to improve the utilization rate of the sealing water inspection device.

[0045] In this embodiment, a movable plate 6 is connected between one of the upper mold assemblies 5 and the frame 1, and the position of the movable plate 6 on the frame 1 is adjustable in the horizontal direction. The driver 51 in one of the upper mold assemblies 5 and one of the support bases 2 are fixed to the frame 1, and the driver 51 in the other upper mold assembly 5 and the other support base 2 are fixed to this movable plate 6. By designing in this way, it is convenient to pre-adjust the position calibration of the upper mold 52 and the other support base 2 in the other upper mold assembly 5 externally. When it is necessary to test top covers of different lengths, it is only necessary to move the movable plate 6 to a preset position without adjusting the other upper mold assembly 5 and the other support base 2 horizontally respectively, so that the water detection test operation of different types of top covers can be quickly met. Preferably, the top of the movable plate 6 is provided with scale lines 7, which are arranged at intervals in the horizontal direction. Through these scale lines 7, the operator can quickly adjust the movable plate 6 to the desired position in the horizontal direction to more quickly meet the water detection test operation of different types of top covers. Preferably, a penetrating adjustment hole 61 is provided on the movable plate 6, and the length of the adjustment hole 61 extends in the horizontal direction. The movable plate 6 can be fixed to the frame 1 by inserting a bolt into the adjustment hole 61. The provision of the adjustment hole 61 also facilitates the horizontal adjustment of the position of the movable plate 6, which has the advantage of simple adjustment.

[0046] In this embodiment, preferably, a first slide groove 16 is provided on the frame 1, and a second slide groove 62 is provided at the bottom end of the movable plate 6. The first slide groove 16 and the second slide groove 62 both extend in the horizontal direction. One of the support seats 2 is inserted in the first slide groove 16, and the other support seat 2 is inserted in the second slide groove 62. By sliding the support seat 2 along the first slide groove 16 or the second slide groove 62, it is convenient to accurately adjust the support seat 2 to directly below the upper mold 52, so that the upper mold 52 can accurately seal the position to be tested when clamping the sealing ring 53 together with the support seat 2.

[0047] The above is merely a preferred embodiment of the present invention and only specifically describes the technical principles of the present invention. These descriptions are intended only to explain the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention, as well as other specific embodiments of the present invention that can be imagined by those skilled in the art without inventive effort, shall be included within the scope of protection of the present invention.
