[0043] The present invention provides a battery insertion and extraction force testing device 100 .

[0044] Please refer to Figure 1In the embodiment of the present invention, the battery plugging and unplugging force testing device 100 includes a protective cover 110, a lifting workbench 180, a fixture 170, a plugging and unplugging mechanism 120, a first sensor 150, a second sensor 160, a controller and a display device 190. The plugging and unplugging mechanism 120 and the lifting workbench 180 are both arranged in the protective cover 110, and the fixture 170 is detachably fixed on the lifting workbench 180. The lifting workbench 180 can be composed of a platform, a motor, a screw transmission mechanism and other components, and the motor drives the screw transmission mechanism to rotate to drive the platform to rise and fall. The plug-in and pull-out mechanism 120 is located above the lifting workbench 180. The plug-in and pull-out mechanism 120 includes an insertion component 130 and a pull-out auxiliary component 140. A mounting frame 111 is provided in the protective cover 110. The insertion component 130 is fixed on the mounting frame 111. The insertion component 130 pushes against the battery 300 to enter the battery compartment 210 of the electronic product 200 installed in the fixture 170. The pull-out auxiliary component 140 is configured to cooperate with the insertion component 130 so that the battery 300 is relatively fixed to the plug-in and pull-out mechanism 120. The first sensor 150 is a force sensor, which is connected to the insertion component 130 and is used to detect the insertion force of the insertion component 130 in the process of the insertion component 130 pushing against the battery 300 to enter the battery compartment 210. The second sensor 160 is a force sensor, which is connected to the pull-out auxiliary component 140 and is used to detect the pull-out force of the pull-out auxiliary component 140 in the process of the battery 300 being separated from the battery compartment 210. The controller and the display device 190 can be fixed together with the protective cover 110, or can be separately provided with the protective cover 110, and the controller and the display device 190 can be integrated together. During the insertion force test, the controller controls the insertion component 130 to push against the battery 300 to enter the battery compartment 210 from top to bottom, and during the extraction force test, the controller also controls the lifting workbench 180 to move downward, at which time the plug-in and extraction mechanism 120 does not move, and the extraction auxiliary component 140 in the plug-in and extraction mechanism 120 is fixedly connected to the battery 300 and is stationary relative to the battery 300, and the battery 300 and the battery compartment 210 are smoothly separated by the downward movement of the lifting workbench 180. The display device 190 displays the insertion force signal obtained by the first sensor 150 and the extraction force signal obtained by the second sensor 160.

[0045] The technical solution of the present invention is to set a plug-in and pull-out mechanism 120 and a lifting workbench 180 in a battery plug-in and pull-out force testing device 100, and drive the insertion component 130 in the plug-in and pull-out mechanism 120 to push the battery 300 into the battery compartment 210. The first sensor 150 detects the insertion force during the insertion of the battery 300 in real time. The lifting workbench 180 moves downward, and the extraction auxiliary component 140 fixes the battery 300 at the top, so that the relative movement between the battery compartment 210 and the battery 300 is driven by the downward movement of the lifting workbench 180, thereby realizing the smooth separation of the battery 300 from the battery compartment 210. The second sensor 160 detects the extraction force during the separation of the battery 300 from the battery compartment 210 in real time, and the display device 190 displays the insertion force and the extraction force in real time, thereby accurately detecting the external force required for the battery 300 to be inserted into and removed from the battery compartment 210, thereby providing an accurate and intuitive parameter basis for designing the performance of the electrode shrapnel of the battery compartment 210 in the electronic product 200, which is beneficial to improving the performance of the electronic product 200.

[0046] Please refer to Figure 4 and Figure 5 , Figure 4 is a top view of the battery compartment 210, Figure 5 for Figure 4 The cross-sectional view at AA of the electronic product 200 is shown in FIG. 1 , wherein after the electronic product 200 is installed in the fixture 170, the battery compartment 210 inside it has an opening toward the plug-in and unplugging mechanism 120, or the battery compartment 210 of some electronic products 200 can be removed separately, and the battery compartment 210 can be directly fixed to the fixture 170 for plug-in and unplugging force testing. Each end of the battery compartment 210 is provided with a positive spring 211 and a negative spring 212, and the positive poles of the two ends of the battery 300 are protruding, and the negative poles are roughly flat. After the battery 300 is pressed into the battery compartment 210, the positive pole of the battery 300 is connected to the negative spring 212, and the negative pole of the battery 300 is connected to the positive spring 211.

[0047] Please refer to Figure 2 and Figure 3 In order to further improve the accuracy of the test, the insertion assembly 130 of the present application includes a power source 131 and a support frame 133 connected to the power source 131. The power source 131 can be a combination of a motor and a lead screw. The support frame 133 includes two driving arms 1331 corresponding to the two ends of the battery 300 respectively. The end of the driving arm 1331 facing the electronic product 200 is provided with a groove 1333 adapted to the outer contour shape of the battery 300. The groove 1333 presents an arc structure adapted to the outer contour shape of the battery 300, and the two driving arms 1331 respectively press against the two ends of the battery 300, so that the battery 300 can be evenly and smoothly loaded into the battery compartment 210, so that the insertion force used by the battery 300 to insert the battery compartment 210 can be more accurately detected.

[0048] Furthermore, the support frame 133 also includes a cross beam 1335, and the two driving arms 1331 are respectively fixedly connected to the two ends of the two driving arms 1331, and the power source 131 is connected to the cross beam 1335. The cross beam 1335 and the driving arms 1331 are both flat and integrated structures. Through such a setting, it is beneficial to achieve the consistency of the movement of the driving arms 1331 during the downward movement of the support frame 133, thereby improving the detection accuracy.

[0049] Furthermore, the extraction auxiliary component 140 includes a hanging member 141 and a traction member 142, wherein the traction member 142 is suspended on the hanging member 141 and surrounds the outer periphery of the battery 300. The extraction auxiliary component 140 of the present application is composed of two detachable parts, wherein the hanging member 141 can be a hook, and the traction member 142 can be a flat belt. Through such a design, when installing the battery 300, the battery 300 can be first fixed to the traction member 142, and then the traction member 142 can be hung on the hanging member 141, which is conducive to the replacement and disassembly of the battery 300 during multiple test tests.

[0050] The suspension member 141 is located between the two driving arms 1331, and the traction member 142 surrounds the middle of the battery 300 and is Figure 2It can be seen that in the present application, the hanging member 141 passes through the hole on the crossbeam 1335, and the upper end of the hanging member 141 is limited and will not be separated from the crossbeam 1335 downward. One end of the hanging member 141 passing through the crossbeam 1335 is connected to the second sensor 160. In combination with the above content, in the present application, when testing the extraction force of the battery 300 in the process of separating from the battery compartment 210, the lifting workbench 180 moves downward. At this time, the plug-in and pull-out mechanism 120 does not move, and the traction member 142 surrounds the middle part of the battery 300, and the two ends of the driving arm 1331 are against the battery 300. In this way, during the downward movement of the battery compartment 210 relative to the battery 300, despite the difference in the structure of the positive and negative poles of the battery 300 and the positive and negative pole spring sheets 212, the friction force at the two contact ends is different; and the so-called extraction force is to overcome the friction force at both ends and the self-weight of the battery 300, and take the battery 300 out of the battery compartment 210. At this time, if there is no auxiliary structure, the battery 300 is simply pulled out by a hook and a flat belt. 0 pulls out the battery compartment 210, the battery 300 will not be smoothly ejected during the process of being ejected from the battery compartment 210, and the positive terminal is usually ejected first with a certain impact force, which will cause inaccurate test results. The extraction process of the battery 300 of the present application utilizes the principle of relative motion. The battery 300 is stationary, while the electronic product 200 moves, thereby ejecting the battery 300 from the battery compartment 210. During the extraction process, the electronic product 200 is fixed on the platform by the fixture 170, and the lifting workbench 180 moves downward. At this time, the driving arm 1331 and the suspension member 141 remain stationary, thereby driving the battery 300 to remain stationary relative to the plug-in and extraction mechanism 120. In addition, due to the existence of the driving arm 1331 during the extraction process of the battery 300, the problem of the battery 300 being ejected from one side first will not occur, and the process is smooth. At this time, the extraction force F of the battery 300 = the pulling force F2 of the suspension member 141 - the pressure F1 of the driving arm 1331. The system will automatically calculate and output the F value in real time and display it on the display device 190.

[0051] Furthermore, in order to ensure that the battery 300 can be stably placed on the traction member 142 , a sticky layer is connected to the surface of the traction member 142 contacting the battery 300 , wherein the sticky layer may be a double-sided adhesive tape.

[0052] The present application also proposes a method for testing the insertion and extraction force of a battery 300, the method comprising the following steps:

[0053] When the electronic product 200 is in the fixture 170 on the lifting workbench 180 and the battery 300 is fixed on the unplugging auxiliary component 140 in the unplugging mechanism 120 .

[0054] Controlling the insertion assembly 130 in the plug-in and pull-out mechanism 120 to move downward so as to push the battery 300 into the battery compartment 210 of the electronic product 200;

[0055] Controlling the lifting platform 180 to move downward so that the battery 300 is separated from the battery compartment 210 of the electronic product 200;

[0056] The insertion force of the battery 300 when entering the battery compartment 210 of the electronic product 200 and the extraction force of the battery 300 when leaving the battery compartment 210 of the electronic product 200 are obtained, and signals of the insertion force and the extraction force are generated.

[0057] The electronic product 200 can be fixed to the fixture 170 manually or automatically by a robot arm, and the battery 300 can be assembled and fixed to the extraction auxiliary component 140 manually. After the fixture 170 or the lifting workbench 180 is equipped with a sensor to detect that the electronic product 200 and the battery 300 have been assembled, the machine is started, the plug-in assembly moves down so that the battery 300 is pushed into the battery compartment 210, and the information of the insertion force is detected by the first sensor 150, and the signal of the insertion force is displayed in real time in the form of a curve on the display device 190. Then the lifting workbench 180 moves down while the plug-in mechanism 120 remains stationary, and the lifting workbench 180 drives the electronic product 200 and the battery compartment 210 to move down, and the battery 300 is separated from the battery compartment 210 through relative movement, and the information of the extraction force is detected by the second sensor 160, and the signal of the extraction force is displayed in real time in the form of a curve on the display device 190. In this way, accurate measurement of the extraction force of the battery 300 can be achieved.

[0058] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
