Description

Technical Field

[0001] The utility model relates to the technical field of power batteries, in particular to a collision testing device. Background Art

[0002] During the production process, the rubber ring of the battery cap is tested for cracking risks by simulating the steel shell seal of the product, thereby preventing the risk of leakage after the battery is sealed. During the continuous large-scale production process, the risk of product cracking is avoided by testing toughness (simulating steel shell seal) and imaging. No such risk was found, but cracked products were found in the products after spraying, assembly, and gluing, and the cracking locations were all at the gate locations. After investigation, it was found that the cracking was caused by product impact. Therefore, it is necessary to design a rubber ring collision test device to test the product's qualification and reduce and improve the risk of product cracking. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] like Figure 1-2As shown, the utility model provides a collision test device, including a test box 1, a product impact acceleration air blowing pipe 2, a product reset air blowing pipe 3 and a product impact baffle 4, an inlet 11 for placing a product a and an observation window 12 for observation are formed on the top plate of the test box 1, the air blowing port of the product impact acceleration air blowing pipe 2 is arranged at the first end of the test box 1, most of the tube body of the product impact acceleration air blowing pipe 2 is horizontal with the top plate of the test box 1, and the air blowing port of the product impact acceleration air blowing pipe is inclined to the top plate of the test box 1. The air port of the product reset air pipe 3 is arranged at the second end of the test box 1, and is arranged opposite to the air port of the product impact acceleration air pipe 2. The tube body of the product reset air pipe 3 is perpendicular to the product impact baffle 4, and the air port of the product reset air pipe 3 is inclined to the top plate of the test box 1. The force is applied to the product a through the observation window 12. The product impact baffle 4 is arranged on the second end face of the test box 1, and a pressure sensor is configured on the product impact baffle 4 to feedback the pressure value of the product a impact.

[0018] The collision test device of the present invention blows air at the product a in the test box 1 through the product impact acceleration blowing pipe 2, giving kinetic energy to the product a, allowing the product a to simulate and increase the impact effect caused by the rotation of the product a in the lower injection molding machine, the circulation, the upper machine, the glue spraying machine and the finished product gluing and feeding, so as to achieve the effect of testing the qualified rate of the product a, and blows air at the product a through the product reset blowing pipe 3 to reset the product a to the initial position, so that the product a can be tested multiple times in a short time, so as to achieve the effect of reproducing the experiment and avoid the complexity of taking out and repeating. The top plate of the test box 1 can prevent the product a from falling out due to excessive acceleration, resulting in experimental failure and waste of the test process. The product impact baffle 4 is provided with a pressure sensor to feedback the pressure value of the product a impact, and plays the function of detecting the size of the pressure value when the product a impacts. In summary, the collision test device of the present invention fills the technical gap and solves the technical problem of the lack of rubber ring testing device in the prior art.

[0019] Specifically, the product hits the pressure sensor of the baffle 4. When product a hits it, the pressure value is detected to check the qualification of product a. For example, in assembly production, the impact force is 1 and the number of impacts is 10. The equipment impact force must be greater than 1 and the number of impacts must be greater than 10. If the number of impacts is too large, for example, 100 times, the impact force is simultaneously increased to 100 and the number of impacts reaches 10 times to check the qualification of product a.

[0020] Specifically, the product resets the air blowing tube 3. In order to check the qualification of product a after the impact, the air flow blows to product a, and product a moves in the opposite direction. When product a is about to move to the starting position, the product impact acceleration air blowing tube 2 is started again to accelerate product a, and an accelerated impact is performed for the second time. If the number of impacts is required to be one, the test can be completed after the first impact.

[0021] In a specific embodiment of the present invention, the observation window 12 is in a long strip shape, extending from the first end to the second end of the test box 1 .

[0022] Furthermore, the width of the long strip-shaped observation window 12 is smaller than the unfolded size of the product a.

[0023] Specifically, the width of the long strip observation window 12 is half of the minimum dimension of the product a, which facilitates observation during blowing and prevents the product a from escaping from the test box 1 .

[0024] In a specific embodiment of the present invention, the insertion port 11 is formed on a section of the observation window 12 .

[0025] In a preferred embodiment of the utility model, the scale assembly includes a side scale, which is installed on the test box 1 through the assembly holes 13 and assembly bolts 14 arranged on the two vertical sides of the test box 1. The side scale is not shown in the drawings. The multiple assembly holes 13 and assembly bolts 14 are for the convenience of installing the side scale. Different specifications of side scales can be selected for products a of different specifications and installed at different positions. The role of the side scale is to locate the position where the product a rebounds after impact. Different products a are damaged with different forces, and the torque can reflect the difference. The side scale is used to mark the position where the product a rebounds after impact, so as to standardize the position and achieve the effect of saving time and effort.

[0026] like Figure 2 As shown, the collision test device of the utility model also includes a control box 5, which is provided with an on-off switch for controlling the opening and closing of the product impact acceleration air blow pipe 2 and the product reset air blow pipe 3, and an adjusting switch for controlling the gas pressure in the product impact acceleration air blow pipe 2 and the product reset air blow pipe 3.

[0027] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
