Detailed Description
It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. Preferred embodiments of the present utility model will now be described in detail with reference to the accompanying drawings.
The utility model provides a battery FPC torque testing device 1000, as shown in figures 1-3, the battery FPC torque testing device 1000 comprises: the torque tester 100, the lever 200 and the clamp assembly 300, wherein the torque tester 100 is provided with a test rod 101 for testing torque; the lever 200 is connected with the test rod 101; the fixture assembly 300 comprises a base 301, an extension rod 302 and a fixture 303, wherein the base 301 is rotationally connected with the extension rod 302, the fixture 303 is arranged on the extension rod 302, and the fixture 303 is used for positioning a battery to be tested; wherein one end of the lever 200 can abut against one end of the extension rod 302.
The test stick 101 is a column-shaped stick for testing the torque of the object to be tested by its rotation angle on the torque tester 100 and displaying the value on the display screen of the torque tester 100.
The lever 200 is directly added on the test rod 101 of the torque tester 100, and the extension rod 302 of the clamp assembly 300 is matched with the lever 200, so that the clamp assembly 300 and the torque tester 100 establish a required connection relation. The test mode has the advantages of simple structure, convenient installation and convenient production and manufacture. Meanwhile, the torque born by the FPC assembly is determined through an accurate numerical value, so that actual production operation is guided more normally, reasonably and accurately, the rejection rate can be effectively reduced, and the production cost is reduced.
Specifically, the fixture assembly 300 can be quickly assembled and quickly detected, and the efficiency of testing the torque of the FPC assembly on the battery to be tested is effectively improved.
Specifically, the distance between the opposite surfaces of the extension rod 302 and the lever 200 in the fixture assembly 300 should be the same, so as to ensure that when the extension rod 302 rotates under control, the extension rod 302 can contact and drive the lever 200 to rotate, and finally the torque born by the FPC assembly is measured; alternatively, the distance between the opposite surfaces of the extension rod 302 and the lever 200 in the clamp assembly 300 should be different, and in this case, a mating portion needs to be provided at one end of the lever 200 and/or the extension rod 302 for abutting against each other, i.e. the lever 200 and/or the extension rod 302 has an "L" shape.
Referring to fig. 3, a receiving groove 3031 is provided on the fixture 303 for receiving a battery to be tested.
When the FPC assembly is twisted, the battery to be tested cannot rotate and shake in the accommodating groove 3031, so that the influence of movement or rotation of the battery to be tested on a test result during testing is avoided, and the accuracy and stability of testing are further improved. Meanwhile, the accommodating groove 3031 can ensure that the battery to be tested cannot rotate along with the torsion of the FPC assembly in the testing process, but transmits the force generated by the torsion of the FPC assembly to the extension rod 302, so that the extension rod 302 rotates and drives the lever 200 to rotate. In addition, the accommodating groove 3031 can also protect the battery to be tested from being damaged or falling in the testing process, so that the testing safety is improved. The receiving groove 3031 can provide a more accurate, stable and safe test environment for torque testing.

In order to solve the above-described problem, the rotation center of the jig 303 and the rotation center of the extension rod 302 are set at the same position, and the moment between the jig 303 and the extension rod 302 at the time of testing can be balanced to ensure that the rotation between the jig 303 and the extension rod 302 is synchronized, thereby avoiding errors and instability at the time of testing.
In this embodiment, in the actual use process of the battery FPC torque testing device 1000, the battery to be tested needs to be placed in the accommodating groove 3031 of the fixture 303, and a part of the area of the accommodating groove 3031 is located at the rotation center of the fixture 303, that is, the part of the accommodating groove 3031 is located at the rotation center of the extension rod 302, when the battery to be tested is placed in the accommodating groove 3031, the FPC assembly on the battery to be tested should be placed in the accommodating groove 3031 of the accommodating groove 3031 located at the rotation center of the fixture 303, so that the value of the torque suffered by the FPC can be obtained more accurately when the FPC assembly is twisted, because when the FPC assembly is located at the rotation center of the extension rod 302, the force applied to twisting the FPC assembly, that is, the force for driving the extension rod 302 to rotate, is not required to be calculated in excess, and the detection result is more convenient and quick.
