Referring to fig. 1 to 3, the present invention discloses a product and jig pairing system 100, which is used for adjusting the number of products on a jig 200 output from a previous station (not shown) to a target number for output, so that the number of products on the jig 200 entering a next station 300 matches with the product number requirement of the next station 300, thereby improving the production efficiency. Specifically, the product and jig pairing system 100 of the present invention includes a manipulator 1 and a controller 2, wherein the manipulator 1 is provided with a plurality of clamping jaw mechanisms 11 for picking and placing products, and the number of the clamping jaw mechanisms 11 is at least a value obtained by subtracting one from a target number. The controller 2 is configured to perform: recording the number of products on the jig 200 and the number of products on the manipulator 1 when entering; summing the number of products on the jig 200 and the number of products on the manipulator 1 when entering, so as to obtain the total number of the products; comparing the total number with the target number, if the total number is smaller than the target number, controlling the idle clamping jaw mechanism 11 of the manipulator 1 to clamp all the products on the jig 200, and then, the number of the products on the jig 200 is zero; if the total number of the products reaches the target number, the gripper mechanism 11 of the manipulator 1 is controlled to place the products on the gripper mechanism on the idle placement positions 210 of the jig 200 until the number of the products on the jig 200 reaches the target number, so that the number of the output products matches with the requirement of the next station 300. The controller 2 may be any electronic device with data processing capability, such as a PLC.
As a preferred embodiment, the number of the gripper mechanisms 11 is one less than the target number, whereby the requirement of the minimum number of gripper mechanisms 11 for achieving the adjustment of the number of products can be met, while the cost of the gripper mechanisms 11 can also be reduced. In one embodiment, the number of jaw mechanisms 11 is four, with a target number of five. Of course, in some embodiments, the number of the gripper mechanisms 11 may be the same as the target number, for example, the number of the gripper mechanisms 11 and the target number are both five. In some embodiments, the number of gripper mechanisms 11 may also be greater than a target number, for example, the number of gripper mechanisms 11 is 5, and the target number is 4. Therefore, the number of the gripper mechanisms 11 and the target number should not be limited as long as the number of the gripper mechanisms 11 smaller than the target number does not exceed one.
Specifically, the controller 2 obtains the number of products on the jig 200 when entering from the information sent from the previous station. Specifically, the previous station may be a detection station, the controller 2 controls the manipulator 1 of the detection station to place a plurality of products on the jig 200 and records the number of the products placed on the jig 200 by the manipulator 1, and then the controller 2 learns which products are not detected by the product detection result information sent by the detection station and controls the manipulator 1 to take away the products which are not detected by the jig 200; at this time, the controller 2 calculates the number of products on the jig 200 at the time of entry.

Specifically, the magnetic switch 111 is disposed on the clamping jaw cylinder 112, and when the controller 2 controls the clamping jaw mechanism 11 to clamp a product, the magnetic switch 111 detects a stroke of the clamping jaw cylinder 112 to know whether the clamping jaw mechanism 11 clamps the product, for example, when the stroke of the clamping jaw cylinder 112 only reaches a preset clamping stroke, it indicates that the clamping jaw mechanism 11 has clamped the product, and at this time, the controller 2 controls the lifting cylinder 113 of the clamping jaw mechanism 11 to drive the product to move upwards; when the stroke that the clamping jaw cylinder 112 can move is long, it indicates that the product is not clamped by the clamping jaw mechanism 11, and at this time, the controller 2 controls the clamping jaw mechanism 11 to clamp the product again, so as to ensure that the clamping jaw mechanism 11 can clamp the product away from the jig 200 according to the control instruction of the controller 2. Further, each placing position 210 of the jig 200 is further provided with a sensor 220 for sensing a product, and the controller 2 receives information sent by the sensor 220 to know whether a product is placed on each placing position 210.
As a preferred embodiment, before the gripper mechanism 11 is controlled by the jig 200 to grip the product, the controller 2 performs: judging the distance between each idle clamping jaw mechanism 11 and each placing position 210 on the jig 200 for placing the product; the vacant gripper mechanism 11 nearest to the placement position 210 where the product is placed is controlled to grip the product. The controller 2 controls the clamping jaw mechanism 11 to place the product in front of the jig 200, and executes: judging the distance between each clamping jaw mechanism 11 which clamps the product and each idle placing position 210 on the jig 200; the gripper mechanism 11 which is closest to the vacant placing position 210 of the jig 200 and has gripped the product is controlled to place the product on the jig 200.
