[0047] When the detection machine is used to detect the cut foam, first, the controller is started to adjust the movement frequency of each unit. Then, the cut foam is placed on the feeding conveying line 1, and the foam to be detected is moved to the transparent glass 3 of the support frame 2 along the feeding conveying line 1, at which time the first detection camera 4 detects the lower surface of the foam. After detection, the push plate 22 on one side is controlled to adsorb and push the foam on the transparent glass 3 to the corresponding loading plate 6, and the push plates 22 on the left and right sides are staggered. After the foam is moved to the loading plate 6, the second detection camera 8 detects the left side of the foam, and then the driving mechanism is started to drive the shaft 7 and the loading plate 6 to rotate 90 degrees, and the foam rotates synchronously with the loading plate 6, so that the second detection camera 8 detects the second side of the foam, and the cycle is repeated until the four sides of the foam are detected by the second detection camera 8. Before transfer, the transfer plate 26 of the transfer mechanism is always located directly above the corresponding loading plate 6, and the third detection camera 10 is opposite to the loading plate 6, so as to detect the upper surface of the foam. The qualified foam is transferred to the corresponding discharge conveying line 9 by the transfer mechanism. The unqualified foam is adsorbed and pushed to the corresponding waste collection box by the suction pushing mechanism.
[0048] The process of adsorbing and pushing the foam to the loading plate 6 by the suction pushing mechanism is as follows: the first linear motor drives the sliding table 21 to move along the guide rail 20 to the transparent glass 3 until the negative pressure suction cup inside the push plate 22 contacts the side of the foam to be detected, and then the negative pressure pump is started to adsorb the foam by negative pressure, and then the push plate 22 is driven to move outward to move the foam to the center of the loading plate 6, and then the adsorption force of the negative pressure suction cup on the foam is released, and the push plate 22 is further moved outward to prevent the push plate 22 from affecting the subsequent rotation of the loading plate 6 and the foam.
[0049] The process of driving the loading plate 6 to rotate by the driving mechanism is as follows: the stepping motor 11 is started, the stepping motor 11 drives the two shafts 7 to rotate synchronously through the driving sprocket 12, the driven sprocket 13 and the chain 14, and then drives the two loading plates 6 to rotate, and the foam on the loading plate 6 rotates synchronously with the loading plate 6, and the stepping motor 11 stops rotating every 90 degrees of the loading plate 6, and then the next rotation driving is performed after the second detection camera 8 records.
[0050] The process of tensioning the chain 14 by the tensioning mechanism is as follows: the driving rod 17 is rotated by the handle, the driving rod 17 is threadedly connected with the limiting block 16, and then the limiting block 16, the support 18 and the tensioning sprocket 19 are driven to move to the chain 14, so as to tension the chain 14, and the chain 14 is always in a tensioned state.
[0051] The process of the transfer mechanism transferring qualified foam is: starting the telescopic cylinder 25 to move the transfer plate 26 downward until the transfer plate 26 contacts the qualified foam on the loading plate 6, and then starting the vacuum pump to make the transfer plate 26 adsorb and grab the foam through the micro suction cup. Then the telescopic cylinder 25 controls the transfer plate 26 and the grabbed foam to move upward synchronously, and after moving to the target height, the second linear motor drives the sliding block 24 to move along the sliding rail 23 to the upper side of the discharge conveying line 9, the transfer plate 26 and the grabbed foam move synchronously with the sliding block 24, and then the foam is lowered to the discharge conveying line 9.
[0052] The process of the suction and pushing mechanism adsorbing and pushing unqualified foam to the waste collection box is: if the foam is unqualified, the suction and pushing mechanism is started to adsorb the unqualified foam again and move outward until the unqualified foam is moved to the upper side of the waste collection box, and then the adsorption force is cancelled, and the unqualified foam automatically falls into the waste collection box under the action of gravity.
[0053] The above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
