In this embodiment, the automatic dismounting device 100 may further optionally include a pressure detecting element 160, as shown in fig. 2 and fig. 3, the pressure detecting element 160 is disposed between the first mounting plate 111 and the second mounting plate 112, two ends of the pressure detecting element 160 respectively abut against the bottom of the first mounting plate 111 and the top of the second mounting plate 112, and is configured to sense a pressure applied to the second mounting plate 112 when the sleeve-type locking claw 131 is sleeved with the knob lock 210, and when the pressure exceeds a set threshold, the pressure detecting element 160 sends an alarm signal to an external control device, and the external control device controls the automatic dismounting device 100 to stop working according to the alarm signal.

Further, the pressure detecting assembly 160 includes, for example, two pressure sensors uniformly distributed between the first mounting plate 111 and the second mounting plate 112 to uniformly measure the force applied on the second mounting plate 112. The upper limit threshold of the pressure alarm value set in the pressure detection assembly 160 is, for example, 7-8 kg, and when the upper limit threshold exceeds the set pressure threshold, an alarm is triggered to stop. Of course, the pressure sensor can change the upper pressure threshold value according to different pressure requirements of products, and the sensor with the matched model can be replaced. Therefore, when the lifting mechanism of the automatic dismounting device 100 causes the bearing mechanism 110 to press the cover plate 200 downward on the carrier 300, if the local stress on the second mounting plate is so large that it exceeds the set pressure threshold, it means that an abnormal situation occurs during the pressing process, such as the cover plate 200 being placed opposite to the carrier 30 or the cover plate 200 being not aligned with the carrier 300 accurately, and the automatic dismounting device 100 automatically stops the next step to reduce the failure rate.

The automatic dismounting device comprises the following working steps:

firstly, a PCB to be assembled and a small magnet to be attached are fed into a carrier 300, the carrier 300 is placed at a feeding position of a main runner track, current is carried to a designated pressing position, a bearing mechanism and a driving mechanism are controlled to be pressed downwards through a lifting mechanism, and a cylinder clamping jaw 142 of a clamping assembly 140 clamps the carrier.

Secondly, the cover plate 200 with the knob lock 210 is put into a feeding position of the auxiliary streamline track, the device recognizes a material signal, the automatic dismounting device 100 moves to the auxiliary streamline cover plate 200 position, the lifting mechanism, the bearing mechanism 110 and the driving mechanism 120 of the automatic dismounting device 100 synchronously descend to a close point of the cover plate 200, and the cylinder clamping jaw 142 grabs the cover plate 200.

Thirdly, the automatic dismounting device 100 moves the cover plate 200 from the secondary streamline to the loading position of the main runner carrier, and presses the cover plate 200 down to the right above the carrier 300 after aligning, and presses the carrier 300 with a force of about 2.5kg, for example, the knob lock 210 on the cover plate 200 is buckled at the right center of the sleeve portion 1312 of the sleeve-type locking claw 131; if the cover 200 and the carrier 300 are not aligned correctly, the pressure detection assembly 160 will alarm over pressure, and the automatic dismounting device 100 will stop the next operation.

Fourthly, after the cover 200 is correctly aligned with the carrier 300, the driving motors 121 of the driving mechanism 120 synchronously drive the sleeve portions 1312 of the sleeve-type locking claws 131 to rotate 90 ° so as to lock the cover 200 onto the carrier 300.

Fifthly, the automatic dismounting device 100 releases the cylinder clamping jaw 142, and the lifting mechanism, the bearing mechanism 110 and the driving mechanism 120 are synchronously lifted and reset.

It should be noted that, the above exemplary description describes the brief steps of locking the cover 200 to the carrier 300, and as another application of the present invention, the process of unlocking the cover 200 from the carrier 300 is a reverse process of the above steps, and the description is not repeated herein.

In summary, the present invention designs a plurality of driving motors respectively corresponding to the plurality of knob locks on the cover plate, and the driving motors can precisely position the cover plate on the carrier and rotate a certain angle to lock or unlock the cover plate on the carrier, thereby replacing the design of belt driving, and solving the problems of easy wear and low precision of belt transmission. The cover plate locking device also comprises a plurality of sleeve type locking claws corresponding to the plurality of driving motors, and the sleeve type locking claws are driven by the driving motors to lock or unlock the cover plate, so that the cover plate locking device has the advantage of obviously improving the working efficiency. In addition, the pressure detection assembly is arranged to detect the pressure born by the sleeve-type locking claw when the cover plate is attached to the carrier, and when the borne pressure exceeds a set threshold value, the alarm is triggered to stop, so that the failure rate is greatly reduced.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
