Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, and particularly relates to a test plug-in unit and a test device. Background Art

[0002] During the battery processing and manufacturing process, it is necessary to test the battery after battery assembly. During the test process, the plug-in terminal needs to be docked with the interface of the battery. Since the docking is generally a rigid docking, there is an impact between the plug-in terminal and the interface of the battery. A certain mechanical impact force will be generated at the moment when the plug-in terminal contacts the interface of the battery during rigid docking. This impact force may be insignificant in a single operation, but considering that battery testing usually involves a large number of repetitive plugging and unplugging actions, the cumulative effect cannot be ignored. Over time, due to the frequent force application on the plug-in terminal, the contact part thereof is prone to wear, affecting the accuracy and reliability of battery measurement.

[0049] In order to extend the service life of the battery test equipment and improve its reliability in use, the present technical solution proposes a test plug-in, including:

[0050] A base 100;

[0051] A floating component 200, slidably disposed on the base 100 along the X direction to have a test position close to the product to be tested and a separation position away from the product to be tested;

[0052] A plug-in terminal 300, disposed on the floating component 200. In the test position, the plug-in terminal 300 is plugged into the product to be tested; in the separation position, the plug-in terminal 300 is detached from the product to be tested;

[0053] A stopper 400, disposed on the floating component 200;

[0054] A buffer 500, disposed on the base 100. In the test position, the buffer 500 elastically abuts against the stopper 400 to reduce the impact between the plug-in terminal 300 and the product to be tested.

[0055] Compared with the prior art, in the technical solution of the present utility model, the test plug-in includes a base 100. A floating component 200 is arranged on the base 100. The floating component 200 is slidably arranged on the base 100 in the X direction. By sliding the floating component 200, the floating component 200 can approach or move away from the product to be tested. The floating component 200 has a test position close to the product to be tested and a separation position away from the product to be tested. A plug-in terminal 300 is arranged on the floating component 200. The plug-in terminal 300 is plugged into the product to be tested at the test position and is disengaged from the product to be tested at the separation position. In addition, a stopper 400 is arranged on the floating component 200, and a buffer 500 is arranged on the base 100. The buffer 500 can elastically abut against the stopper 400 at the test position to absorb the impact when the plug-in terminal 300 is plugged into the product to be tested, thereby reducing the wear of the plug-in terminal 300 and the product to be tested, prolonging the service life of the test plug-in and improving its reliability in use.

[0056] As Figure 1 and Figure 2 , in an embodiment of the present utility model, the test plug-in includes a base 100. The base 100 is a frame structure. The base 100 can be fixedly screwed to the base 100 of the test equipment or the end of the manipulator. The base 100 serves as a stable foundation for the entire test plug-in and is made of high-strength and wear-resistant materials, ensuring the stability of the entire structure and the reliability of long-term use. The floating component 200 arranged on the base 100 can also be a frame structure. The floating component 200 can be slidably connected to the base 100 through a slide rail, enabling the floating component 200 to move relative to the base 100 in the X direction. In this solution, the X direction is the direction of approaching or moving away from the product horizontally. By sliding, the floating component 200 has a test position close to the product to be tested and a separation position away from the product to be tested. A plug-in terminal 300 is arranged on the side of the floating component 200 close to the product to be tested. The plug-in terminal 300 can be directly installed on the floating component 200. At the test position, the plug-in terminal 300 is in close contact with the interface of the battery to be tested through a precise guiding mechanism, ensuring the lossless transmission of the test signal. When moving to the separation position, the plug-in terminal 300 is disengaged from the battery interface. In addition, a stopper 400 is arranged on the floating component 200, and a buffer 500 is arranged on the mounting base 100. The function of the stopper 400 is to work together with the buffer 500 to jointly relieve the mechanical impact during the plugging process. The buffer 500 is an elastic element installed on the base 100, such as high-elastic rubber or a spring. At the test position, the buffer 500 elastically abuts against the stopper 400, using elastic potential energy to absorb the impact force generated when the plug-in terminal 300 is docked with the interface of the product to be tested, protecting the contact surfaces of both sides, thereby prolonging the service life of the test plug-in and improving the reliability of the test data at the same time.

[0057] As Figure 2 , in an embodiment of the present utility model, the floating assembly 200 includes:

[0058] A connecting plate 210, which is slidably connected to the base 100 and moves along the X direction;

[0059] A first floating plate 220, which is slidably connected to the connecting plate 210;

[0060] A first elastic component 230, which elastically connects the connecting plate 210 and the first floating plate 220 to enable the first floating plate 220 to float in the Y direction;

[0061] A second floating plate 240, which is slidably connected to the first floating plate 220;

[0062] A second elastic component 250, which elastically connects the second floating plate 240 and the first floating plate 220 to enable the second floating plate 240 to float in the Z direction;

[0063] A third floating plate 260, which is slidably connected to the second floating plate 240;

[0064] A third elastic component 270, which elastically connects the third floating plate 260 and the second floating plate 240 to enable the third floating plate 260 to float in the X direction;

[0065] Wherein, the plug-in terminal 300 is arranged on the third floating plate 260, and the stopper 400 is arranged on the connecting plate 210.

[0066] The technical solution of this embodiment can compensate for the position deviation when the test plug-in is plugged into the battery, thereby improving the accuracy of the test. In this solution, the floating component 200 includes a connecting plate 210, which is slidably connected to the base 100 and can move in the X direction. The connecting plate 210 is used to install other components of the floating component 200. A first floating plate 220 is provided on the connecting plate 210, and the first floating plate 220 can be slidably connected to the connecting plate 210 through a slide rail. The first floating plate 220 can move in the Y direction relative to the connecting plate 210, and the Y direction is a direction perpendicular to the X direction in the horizontal plane. In addition, the first floating plate 220 is elastically connected to the connecting plate 210 through a first elastic member. The first elastic component 230 can be a spring.

The second floating plate 240 can be maintained at a specific position when no force is applied in the Z direction, and can also float in the Z direction according to the direction of the applied force when a force is applied. In addition, a third floating plate 260 is also slidably arranged on the second floating plate 240. The third floating plate 260 can move relative to the second floating plate 240 in the X direction. The third floating plate 260 is elastically connected to the second floating plate 240 through the third elastic component 270, so that the third floating plate 260 can float in the X direction. The plug-in terminal 300 is arranged on the third floating plate 260. In this way, the plug-in terminal 300 can float in the X direction, the Y direction and the Z direction relative to the base 100, so as to supplement the position deviation between the plug-in terminal 300 and the interface of the product to be tested during the test, thereby improving the accuracy of the test. In addition, the floating of the third floating plate 260 in the X direction can also absorb the impact when the plug-in terminal 300 is plugged into the product to be tested.

The first guide rod extends along the Y direction, and the connecting plate 210 is provided with ribs on opposite sides along the Y direction. The first guide rod movably passes through the ribs, so that the first floating plate 220 can move along the Y direction under the guidance of the first guide rod, which can further improve the stability of the first floating plate 220 during movement. In addition, the first elastic member is sleeved on the outside of the first guide rod, and the first elastic member can be an axial compression spring. The ribs of the first floating plate 220 and the ribs of the connecting plate 210 are respectively abutted against the two ends of the axial compression spring.
