The controller is also used to control the output end of the driving module 3 to lift according to the second feedback information of both the first anti-fooling detection module 5 and the second anti-fooling detection module 6.

[0057] The anti-fooling detection device for the battery cover plate of the present utility model, through integrating the machine body 1, the positioning base body 2, the driving module 3, the pressing plate 4, the first anti-fooling detection module 5, the second anti-fooling detection module 6 and the controller, can use the positioning base body 2 to position the battery cover plate 7. At the same time, through the cooperation of the driving module 3 and the pressing plate 4, the battery cover plate 7 can be restricted on the positioning base body 2. While being able to accurately position the battery cover plate 7, it can also realize the positioning of the battery cover plate 7 by the first anti-fooling detection module 5, ensuring that the first anti-fooling detection module 5 can detect the positions of the positive electrode column and the negative electrode column in the battery cover plate 7. At the same time, it ensures that the second anti-fooling detection module 6 can detect the positions of the light cover plate and the lower plastic in the battery cover plate 7.

And the controller can receive the first feedback information or the second feedback information of the second anti-fooling detection module 6. At the same time, the controller can send out an alarm message according to the first feedback information, that is, when the second anti-fooling detection module 6 detects that the light cover plate and the lower plastic are installed reversely, the controller sends out an alarm message. It realizes that when the positive electrode column and the negative electrode column are installed reversely and / or the light cover plate and the lower plastic are installed reversely, the controller sends out an alarm message to remind the user that the current battery cover plate 7 is unqualified. At this time, the user needs to manually start the driving module 3, so that the output end of the driving module 3 is lifted to drive the pressing plate 4 and the first anti-fooling detection module 5 away from the positioning base body 2, so as to facilitate the removal of the battery cover plate 7.

It realizes the automatic anti-fooling detection of the battery cover plate 7, can effectively avoid problems such as misoperation and missed inspection, and thus can improve the detection accuracy.

[0058] See Figures 1 - 2 , in an embodiment, the first anti-fooling detection module 5 includes:

[0059] The first color recognition sensor 51, the first color recognition sensor 51 is electrically connected to the controller, and the first color recognition sensor 51 is used to detect the positive electrode column on the battery cover plate 7; and

[0060] The second color recognition sensor 52, the second color recognition sensor 52 is electrically connected to the controller, and the second color recognition sensor 52 is used to detect the negative electrode column on the battery cover plate 7;

[0061] The controller is used to issue an alarm message according to the first feedback information of the first color recognition sensor 51 and / or the second color recognition sensor 52. That is, the color of the positive electrode post (the positive electrode post is generally silver) is recognized by the first color recognition sensor 51, and a feedback signal is output to the controller when the first color recognition sensor 51 recognizes the correct color of the positive electrode post. The controller determines whether the positive electrode post is installed in reverse according to the feedback signal. Similarly, the color of the negative electrode post (the negative electrode post is generally yellow) is recognized by the second color recognition sensor 52, and a feedback signal is output to the controller when the second color recognition sensor 52 recognizes the correct color of the negative electrode post. The controller determines whether the negative electrode post is installed in reverse according to the feedback signal.

[0062] See Figures 1 - 3 , in one embodiment, both the first color recognition sensor 51 and the second color recognition sensor 52 are arranged on the top of the pressing plate 4;

[0063] The pressing plate 4 has a first light-transmitting hole 41 and a second light-transmitting hole 42. The first light-transmitting hole 41 and the second light-transmitting hole 42 penetrate the pressing plate 4 vertically. The first light-transmitting hole 41 is aligned with both the light source and the optoelectronic element of the first color recognition sensor 51, and the second light-transmitting hole 42 is aligned with both the light source and the optoelectronic element of the second color recognition sensor 52. Since both the first color recognition sensor 51 and the second color recognition sensor 52 are located on the top of the pressing plate 4, the space utilization rate of the top of the pressing plate 4 can be improved, the thickness of the pressing plate 4 can be avoided from increasing, and the overall structure of the pressing plate 4 can be made more compact. At the same time, since the pressing plate 4 has the first light-transmitting hole 41 and the second light-transmitting hole 42, the installation and positioning of the first color recognition sensor 51 can be realized by aligning the first light-transmitting hole 41 with both the light source and the optoelectronic element of the first color recognition sensor 51, so that the light emitted by the first color recognition sensor 51 can irradiate the positive electrode post to ensure the detection of the positive electrode post. Similarly, the installation and positioning of the second color recognition sensor 52 can be realized by aligning the second light-transmitting hole 42 with both the light source and the optoelectronic element of the second color recognition sensor 52, so that the light emitted by the second color recognition sensor 52 can irradiate the negative electrode post to ensure the detection of the negative electrode post.

[0064] In other embodiments, the first anti-fooling detection module 5 may specifically be a camera, and the positive electrode post or the negative electrode post is photographed by the camera and the colors of the positive electrode post and the negative electrode post are recognized by the controller, which can also realize the anti-fooling detection of the positive electrode post and the negative electrode post.

[0065] See Figure 2 and Figure 3 , in one embodiment, the second anti-fooling detection module 6 includes:

[0066] The ejector pin 61 is movably disposed on the positioning base body 2 in the up-and-down direction. The ejector pin 61 is used for plugging and mating with the liquid injection hole in the battery cover plate 7. When the optical cover plate or the lower plastic is installed reversely, the ejector pin 61 is pressed downward by the battery cover plate 7 and moves downward;

[0067] An elastic member (not shown in the figure), the elastic member is disposed between the positioning base body 2 and the ejector pin 61. The elastic member is used for floatingly supporting the ejector pin 61 so that the ejector pin 61 can float up and down; and

[0068] An inductor 62, the inductor 62 is disposed on the positioning base body 2, and the inductor 62 is electrically connected to the controller. When the ejector pin 61 is pressed downward by the battery cover plate 7, the inductor 62 is triggered to send a first feedback message to the controller. When the optical cover plate and the lower plastic are correctly installed, the upper part of the ejector pin 61 passes through the liquid injection hole of the battery cover plate 7, and the ejector pin 61 will not be pressed downward. When the optical cover plate and the lower plastic are installed reversely, the ejector pin 61 is pressed downward by the battery cover plate 7 and moves downward until the inductor 62 is triggered, so that the inductor 62 sends a first feedback message to the controller, thereby enabling the controller to send an alarm message. This second anti-fooling detection module 6 is simple and practical in structure, low in cost, and can improve the anti-fooling detection accuracy.

[0069] In one embodiment, the inductor 62 is a photoelectric sensor, so that there is no contact between the ejector pin 61 and the photoelectric sensor. That is, only when the ejector pin 61 is pressed downward until the lower part of the ejector pin 61 moves to the light-emitting area of the photoelectric sensor, the photoelectric sensor can be triggered to feed back a signal to the controller, which is beneficial to improving the detection accuracy.

[0070] More specifically, the photoelectric sensor is a U-shaped photoelectric sensor, and the lower part of the ejector pin 61 is movably inserted into the slot of the U-shaped photoelectric sensor in the up-and-down direction. This slot is also the light-emitting area of the U-shaped photoelectric sensor.

[0071] Of course, in other embodiments, the inductor 62 can also be a contact inductor 62, such as a limit switch.

[0072] See Figure 3 , in one embodiment, the positioning base body 2 has a guiding hole, and the guiding hole penetrates through the positioning base body 2 in both the up-and-down directions;

[0073] The ejector pin 61 is movably inserted into the guiding hole in the up-and-down direction;

[0074] The inductor 62 is disposed at the bottom of the positioning base body 2. In this way, the guiding hole and the ejector pin 61 can be used in cooperation to guide the ejector pin 61, making the movement of the ejector pin 61 smoother.

[0075] See Figure 3 , in one embodiment, the guiding hole includes:

[0076] The upper guiding section 231 is engaged with the upper part of the ejector pin 61 to guide the movement of the upper part of the ejector pin 61;

[0077] The lower guiding section 211 is engaged with the lower part of the ejector pin 61 to guide the movement of the lower part of the ejector pin 61; and

[0078] The limiting section 221 is located between the upper guiding section 231 and the lower guiding section 211. The limiting section 221 connects the upper guiding section 231 and the lower guiding section 211, and the aperture of the limiting section 221 is larger than the apertures of both the upper guiding section 231 and the lower guiding section 211;

[0079] The ejector pin 61 is provided with a limiting portion 611, and the limiting portion 611 is engaged with the limiting section 221 to prevent the ejector pin 61 from disengaging from the guiding hole, so that the ejector pin 61 is reliably installed on the positioning base 2;

[0080] The elastic member is arranged between the bottom wall of the limiting portion 611 and the bottom wall of the limiting section 221 to provide a floating support for the ejector pin 61, so that the ejector pin 61 can automatically return to the initial state after being pressed down.

[0081] See Figure 3 , in one embodiment, the positioning base 2 includes:

[0082] The base 21 is arranged on the machine body 1. The base 21 has a lower guiding section 211 and a mounting groove 212. The mounting groove 212 is located on the top surface of the base 21, and the mounting groove 212 communicates with the lower guiding section 211;

[0083] The connecting seat 22 is arranged in the mounting groove 212. The connecting seat 22 and the base 21 form the limiting section 221; and

[0084] The top seat 23 is arranged on the top of the base 21 and covers the connecting seat 22. The top seat 23 has an upper guiding section 231 and a positioning groove 232. The positioning groove 232 is located on the top surface of the top seat 23, and the positioning groove 232 communicates with the upper guiding section 231. The positioning groove 232 is used to cooperate with the battery cover plate 7. In this way, during installation, the connecting seat 22 can be first sleeved on the ejector pin 61, and then the connecting seat 22 can be installed in the mounting groove 212. At the same time, ensure that the lower part of the ejector pin 61 is inserted into the lower guiding section 211 and the elastic member is arranged between the bottom wall of the limiting portion 611 and the bottom wall of the limiting section 221. Finally, the top seat 23 can be sleeved on the upper part of the ejector pin 61 and installed on the top of the base 21, which can greatly reduce the installation difficulty of the ejector pin 61 and the elastic member and is beneficial to improving the assembly efficiency of the ejector pin 61 and the elastic member.

[0085] In one embodiment, the elastic member can be a spring. The spring is sleeved on the lower part of the ejector pin 61. The upper end of the spring abuts against the bottom wall of the limiting portion 611, and the lower end of the spring abuts against the bottom wall of the limiting section 221.

[0086] Of course, in other embodiments, the elastic member can also be a shrapnel or other applicable elastic structures, as long as it can provide elastic support for the ejector pin 61.

[0087] In one embodiment, the top of the body 1 has a receiving cavity 11. The sensor 62 is arranged in the receiving cavity 11 to house the sensor 62, avoiding the sensor 62 being exposed and easily damaged and affecting the appearance.

[0088] In one embodiment, the top surface of the positioning base 2 has a positioning groove 232. The positioning groove 232 is used to cooperate with the battery cover plate 7 to position the battery cover plate 7, facilitating the quick and correct installation of the battery cover plate 7 on the positioning base 2.
