Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0023] Such as Figures 1-4 shown in the first embodiment: A compression resistance experiment device for a lithium battery shell includes a support frame 1, and an experimental part for the compression resistance experiment of the lithium battery shell is connected to the support frame 1. The experimental part includes: a hydraulic cylinder assembly 2 installed at the top of the support frame 1, and a pressing plate 3 for squeezing the lithium battery shell is installed at the bottom of the hydraulic cylinder assembly 2; a conveying part 5 installed on the lower side of the support frame 1 for conveying the lithium battery shell. The conveying part 5 includes a conveyor belt assembly 52 connected to the support frame 1, and a second motor 51 for providing drive for the conveyor belt assembly 52 is connected to the support frame 1;

[0024] The adjusting member 4 is installed on the lower side of the support frame 1 for limiting and supporting the lithium battery housing. The adjusting member 4 includes two groups of support seats 41 installed on the front side and the rear side of the conveyor belt assembly 52. At the ends of the two groups of support seats 41 away from the conveyor belt assembly 52, pulley assemblies 42 are connected. In the middle of the upper ends of the two groups of support seats 41, screw rods 43 connected to the pulley assemblies 42 are rotatably connected. The two screw rods 43 are both screw-connected with moving frames 44 slidably connected to the support seats 41. A limiting plate 45 is fixedly connected to the upper side of the moving frame 44 close to the conveyor belt assembly 52. A scraping strip 46 is provided on the upper surface of the limiting plate 45 close to the upper surface of the conveyor belt assembly 52. A first motor 47 for driving the two pulley assemblies 42 is installed on the upper end of the support frame 1. A number of connecting rods 48 are fixedly connected between the adjacent ends of the two groups of support seats 41;

[0025] The output end of the second motor 51 is coaxially and fixedly connected to the driving conveyor roller in the conveyor belt assembly 52. The first motor 47 and the second motor 51 are both servo motors; the thread directions of the two screw rods 43 are opposite. On both sides of the upper end of the support seat 41, limiting rods slidably connected to the moving frame 44 are fixedly connected; a rubber washer is sleeved on the protruding end of the scraping strip 46, a sponge sleeve is sleeved on the surface of the limiting plate 45, and a pressure sensor electrically connected to an external controller is provided on the upper surface of the scraping strip 46; the output end of the first motor 47 is coaxially and fixedly connected to the driving pulleys in the two pulley assemblies 42 respectively, and the driven pulleys in the pulley assemblies 42 are coaxially and fixedly connected to the screw rods 43; by making the second motor 51, the conveyor belt assembly 52, the first motor 47, the two groups of support seats 41, the pulley assemblies 42, the screw rods 43, the moving frames 44, the limiting plates 45, and the scraping strips 46 cooperate with each other, the lithium battery housing is conveyed to the lower side of the pressing plate 3, the pressing plate 3 is positioned and supported under it, and it is separated from the conveyor belt assembly 52 to prevent damage to the conveyor belt assembly 52 used for conveying during the compressive test;

[0026] As Figures 1-4 shown in the second embodiment, the main difference from the first embodiment is that:

[0027] The conveying member 5 further includes an electric slide rail 53 installed on the upper end of the support frame 1. A limiting frame 54 is slidably connected to the lower side of the electric slide rail 53. Limiting grooves slidably connected to the limiting frame 54 are provided on the inner sides of the two limiting plates 45. The electric slide rail 53 adjusts the position of the limiting frame 54, and the limiting frame 54 slides along the limiting grooves in the limiting plates 45 to block lithium battery housings of corresponding sizes as required, which helps the subsequent adjusting member 4 to position the lithium battery housing.

[0028] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0029] During use, the user sets up a recycling bin at the lower left side of the conveyor belt assembly 52, adjusts the position of the limit frame 54 through the electric slide rail 53, and the limit frame 54 slides along the inner limit grooves of the two sets of limiting plates 45. Start the second motor 51, and the second motor 51 drives the conveyor belt assembly 52 to operate, allowing an external transmission part to convey the lithium battery case to be tested to the upper side of the conveyor belt assembly 52. The conveyor belt assembly 52 conveys the lithium battery case. After the lithium battery case contacts the limit frame 54, the limit frame 54 blocks the lithium battery case, and then turn off the second motor 51;

[0030] Start the first motor 47. The first motor 47 drives the two sets of screw rods 43 to rotate respectively through the two sets of pulley assemblies 42. Since the thread directions of the two sets of screw rods 43 are opposite, the two moving frames 44 drive the limiting plates 45 and the shovel strips 46 to slide along the limit frame 54 under the action of the rotating screw rods 43. The two shovel strips 46 first shovel the lithium battery case onto their upper surfaces, and then the two limiting plates 45 respectively perform limit processing on the front side and the rear side of the lithium battery case. Turn off the first motor 47 and start the hydraulic cylinder assembly 2. The hydraulic cylinder assembly 2 drives the pressing plate 3 to move downward. After the pressing plate 3 contacts the top of the lithium battery case, apply the corresponding pressure required for the experiment to it. The two shovel strips 46 provide support for the lower side of the lithium battery case and detect the pressure received through the pressure sensor. After the detection is completed, reset each link. At this time, the lithium battery case after the compressive test contacts the pulley assembly 42 again. Let the output end of the second motor 51 rotate in the reverse direction, and the conveyor belt assembly 52 conveys the lithium battery case in the reverse direction. Finally, the lithium battery case falls into the recycling bin.
