Referring to fig. 6, when the battery top sheet 100 is properly placed (i.e., in a prescribed orientation) on the mold core 310, the two metal probes 330 are electrically connected through the battery top sheet 100, and the detection device detects that the two metal probes 330 are in a conductive state. Referring to fig. 7, when the upper and lower sides of the battery top sheet 100 are reversed, the two metal probes 330 respectively extend into the two grooves 102 so as not to contact the battery top sheet 100, and at this time, the detection device detects that the two metal probes 330 are in a disconnected state; whereby it can be judged whether the battery top sheet 100 is put upside down.
The mold core 310 is provided with an induction through hole 315 corresponding to a position right below the liquid injection hole 103 when the battery top cover plate 100 is correctly placed, the fool-proof detection unit further comprises a detection switch 335, and the upper end of the detection switch 335 extends into the induction through hole 315 upwards and is fixedly adhered to the hole wall of the induction through hole 315. The detection switch 335 is used for detecting whether the upper end of the sensing through hole 315 is blocked, and if so, determining that the battery top cover 100 is reversed in the left-right direction.
Of course, in other embodiments, the sensing through hole 315 may be disposed at a position on the mold core 310 corresponding to the position directly below the liquid injection hole 103 when the battery top cover 100 is reversely placed in the left-right direction, and the detection switch 335 may be disposed in the sensing through hole 315 to detect whether the upper end of the sensing through hole 315 is blocked; if there is a shade, it is determined that the battery top sheet 100 is correctly placed in the left-right direction.
The working principle of this embodiment is as follows:
referring to fig. 1 to 7, when the battery top cover 100 is subjected to laser engraving, the leads 334 connected to the two metal probes 330 are respectively connected to a detection device, the detection switch 335 is electrically connected to the detection device, and the detection device is connected to a control interface of the laser engraving device. When the battery top sheet 100 is properly placed on the mold core 310, the two metal probes 330 are electrically connected through the battery top sheet 100, and the detection device detects conduction between the two metal probes 330, determines that the battery top sheet 100 has been placed on the mold core 310, and that the upper and lower surfaces of the battery top sheet 100 are properly placed. At this time, the detection switch 335 does not detect that the sensing through hole 315 is blocked, and does not send a reverse signal to the detection device; the detection equipment does not receive the reverse signal sent by the detection switch 335, and judges that the left-right direction of the battery top cover plate 100 is placed correctly, so that the detection equipment judges that the battery top cover plate 100 is placed correctly, and sends a control signal to the laser etching equipment to control the laser etching equipment to work, and the laser etching equipment carries out laser etching codes on the laser etching area 104 of the battery top cover plate 100 according to a preset program.
When the upper and lower sides of the battery top sheet 100 are reversed, the two grooves 102 of the battery top sheet 100 face downward, so that the two metal probes 330 respectively protrude into the two grooves 102 so as not to contact the battery top sheet 100, and the two metal probes 330 are in a disconnected state. At this time, the detection device detects that the two metal probes 330 are not conducted, and therefore, it is still determined that the battery top cover sheet 100 is not placed on the mold core 310, so that a control signal is not sent to the laser etching device, and the laser etching device does not work.
When the battery top cover 100 is put in reverse in the left-right direction, the battery top cover 100 shields the upper aperture of the sensing through hole 315. Although the two metal probes 330 are electrically connected through the battery top sheet 100 at this time, the detection device detects the conduction between the two metal probes 330, it is determined that the battery top sheet 100 has been placed on the mold core 310, and that the upper and lower surfaces of the battery top sheet 100 are properly placed. However, the detection switch 335 detects that the sensing through hole 315 is blocked, and sends a signal to the detection device. After receiving the reverse signal, the detection device judges that the left and right directions of the battery top cover plate 100 are reversed, so that a control signal is not sent to the laser etching device, and the laser etching device still does not work. Therefore, when the upper surface and the lower surface of the battery top cover plate 100 are reversely placed or the left and right directions are reversely placed, the laser engraving equipment can be used for carrying out laser engraving codes on the non-laser engraving area 104 of the battery top cover plate 100, so that the battery top cover plate 100 is scrapped.
In this embodiment, by using the principle that the position of the liquid injection hole 103 is changed when the battery top cover 100 is reversed in the left-right direction, the detection switch 335 is provided on the mold core 310 to detect the position of the liquid injection hole 103, so as to determine whether the battery top cover 100 is reversed in the left-right direction; by utilizing the two grooves 102 arranged on the top surface of the battery top cover plate 100, the metal probes 330 are respectively arranged at the positions corresponding to the two grooves 102 on the mold core 310, and whether the upper surface and the lower surface of the battery top cover plate 100 are reversely placed can be judged by detecting whether the metal probes 330 are in contact with the battery top cover plate 100, so that the fool-proof detection function of whether the battery top cover plate 100 is correctly placed on a jig can be realized, and the battery top cover plate 100 scrapping caused by carrying out radium carving codes on the non-radium carving area 104 of the battery top cover plate 100 is avoided.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the present utility model, which is intended to be covered by the claims of the present utility model.
