Further, the laser engraving mechanism 120 further includes a dust removing device 137 electrically connected to the control device, and the dust removing device 137 is disposed corresponding to the engraving position and is adapted to remove dust from the engraved battery. Referring to fig. 3, the dust removing device 137 is disposed near the carving position of the transfer platform 123, and when the laser 122 carves the battery or after carving is completed, the dust removing device 137 removes dust. Illustratively, the dust extraction device 137 may blow dust by blowing gas toward the nozzles of the battery in the engraving position (or in other positions); further, the dust removing device 137 may suck dust on the battery by sucking through a nozzle near the battery at the engraved position (or at other positions). It is conceivable that the effect of carving the pattern can be conveniently detected at least after dust removal, improves detection accuracy.

Without loss of generality, the dust removal mechanism 137 may also perform a dust removal process before the battery is engraved.

Without loss of generality, referring to fig. 3, the laser engraving mechanism 120 further comprises a temperature detecting device 138 electrically connected to the control device, the temperature detecting device 138 being arranged corresponding to the engraving position and adapted to detect the temperature of the engraved battery. It will be appreciated that this allows the cell temperature to be found too high in time during laser engraving.

It should be noted that, as an alternative embodiment of the present utility model, the visual detection component 131 may be further configured to measure an error of the laser engraving pattern of the battery, and then feed back the measured error of the laser engraving pattern to the control device, so as to correct the error of the laser engraving pattern in real time, thereby reducing the occurrence rate of defective products. At this time, the vision detecting assembly 131 may include a high beam lens and a CCD camera.

Example 2:

the working procedure of the laser engraving and detecting device 10 of the present utility model is:

referring to fig. 1 to 3, the battery flows in from the feeding mechanism 110, and after the battery is in place, the positioning device 135 photographs, acquires the spatial position of the battery, and sends the spatial position information of the battery to the control device, and the control device controls the carrying manipulator 121a to suck the battery from the feeding mechanism 110. The battery is moved to a position right above the code scanning mechanism 136, the code scanning mechanism 136 scans the two-dimensional code of the lower surface of the battery, and then the product is placed on the transfer platform 123 mechanism (according to the space position of the battery given by the positioning device 135, the carrying manipulator 121a adjusts the posture of the battery and the material taking position of the transfer platform 123 mechanism). The vacuum device of the transfer platform 123 is turned on, so that the battery is fixed and then moved below the laser 122 (i.e., the carving position), and the laser 122 carves the surface of the battery (such as a place of production, logo, two-dimensional code, date of production, etc.).

The temperature detection device detects the temperature of the surface of the battery in real time when the battery is engraved; the dust removing device 137 operates to remove dust from the battery surface. After the laser 122 engraves, the transfer platform 123 moves the battery to below the handling robot 121a (i.e., the material taking position).

In the present embodiment, the turntable mechanism 134 has thereon a first station corresponding to the laser engraving mechanism 120, a second station corresponding to the visual inspection assembly 131, a third station corresponding to the first discharging mechanism 132, and a fourth station corresponding to the second discharging mechanism 133, the first station, the second station, the third station, and the fourth station being arranged at 90 degrees from each other in the circumferential direction of the turntable mechanism 134. The conveyance robot 121a moves the battery to the turntable mechanism 134, and the turntable mechanism 134 is vacuum-opened to rotate the battery by 90 ° after fixing. The vision detection component 131 photographs the engraved portion of the battery surface, detects the engraved portion through an algorithm, uploads the battery information to the customer's production system, and then the turntable mechanism 134 rotates 90 °, if the detection result is good: the mechanical arm mechanism of the first discharging mechanism 132 moves the battery on the turntable to the first discharging belt line mechanism; if the detection result is a defective product: the carousel mechanism 134 continues to rotate 90 ° and the robot mechanism of the second discharge mechanism 133 moves the batteries on the carousel onto the second discharge belt line mechanism.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
