Without prejudice to understanding, the drawings of the present description do not show a specific structural view of the pick-and-place labelling robot.
The first ejection driving element 41 is further provided with a position sensor 6, the position sensor 6 is electrically connected to the controller, and the position sensor 6 is configured to detect whether the first ejector pin assembly 42 is retracted to an initial position;
when the position sensor 6 detects that the first ejector pin assembly 42 retracts to the initial position, the controller sends an ejection working instruction to the second ejection driving element 51 and sends a picking and labeling working signal to the picking and labeling mechanical arm; the second ejection driving part 51 drives the second ejector pin assembly 52 to eject the injection molding to the part taking and labeling mechanical arm according to the working instruction; and the mechanical arm for picking and labeling the injection molding piece places the label in the mold of the movable mold plate 1 according to the working signal and grabs the injection molding piece.
The initial position is the position when the first ejector pin component is not ejected out of the movable template.
Specifically, the position sensor 6 may be a proximity switch fixed to the first ejector driving member 41, and a metal rod 7 is connected to the back surface of the first ejector plate 43, and when the first ejector plate 43 is retracted to the initial position, the metal rod 7 is just sensed by the proximity switch.

The in-mold labeling injection molding system of this application embodiment utilizes first ejection mechanism to ejecting injection molding to 2 sides of fixed die plate when the die sinking through set up first ejection mechanism in 1 side of movable die plate, sets up second ejection mechanism in 2 sides of fixed die plate, utilizes second ejection mechanism to ejecting injection molding to getting on a labeling arm. And the first ejection mechanism, the second ejection mechanism and the workpiece taking and labeling mechanical arm are linked, so that the workpiece taking and labeling mechanical arm can take and label simultaneously and does not interfere with the first ejector pin assembly 42.
As shown in fig. 2, in an exemplary embodiment, the in-mold labeling in the embodiment of the present application is performed by the steps of:
step S0.2: the injection molding machine is opened, the movable mold plate 1 is driven by the mold locking driving device 3 to move away from the fixed mold plate 2, and meanwhile, a first ejector pin assembly 42 arranged on the movable mold plate 1 is driven by a first ejection driving part 41 to eject an injection molding piece onto the fixed mold plate 2;
step S1: the part taking and labeling mechanical arm extends between the fixed template 2 and the movable template 1;
step S2: detecting whether the first ejector pin assembly 42 arranged on the movable mould plate 1 is retracted to the initial position; if yes, go to step S3; if not, the controller sends an alarm working instruction;
step S3: the part taking and labeling mechanical arm places a label in a mold of the movable mold plate 1, the second ejector pin component 52 arranged on the fixed mold plate 2 is ejected out, the injection molding part is ejected out to the part taking and labeling mechanical arm, and the part taking and labeling mechanical arm grabs the injection molding part.
In actual production, due to the design problems of the product structure and the mold structure, some injection molded parts can be left in the male mold after mold opening, and some injection molded parts can be left in the female mold after mold opening. In this embodiment, the mold on the movable platen 1 side is a female mold, and the mold on the fixed platen 2 side is a male mold. To realize labeling and part taking simultaneously, the injection molding part needs to be left in the male mold after mold opening, so that the part taking and labeling mechanical arm can place the label in the female mold conveniently. Therefore, for a product which is left in the female die after the die opening, an ejector pin is needed to be added, and the ejector pin ejects the injection molding part to the male die during the die opening. In order not to affect the labeling of the mechanical arm of the subsequent picking and labeling machine, the first ejector pin assembly 42 on the female mold side must be retracted to the initial position before the picking and labeling mechanical arm performs the labeling, so that the second ejection mechanism and the picking and labeling mechanical arm of the embodiment are linked with the first ejection mechanism, and the interference between the picking and labeling mechanical arm and the first ejector pin assembly 42 is avoided.
If the position sensor 6 does not detect that the first thimble assembly 42 is retracted to the initial position within a certain time, the controller sends an alarm operation command to the alarm device. The alarm device may be a buzzer, a malfunction light, etc. The predetermined time is preset data, and is specifically adjusted according to the moving speed of the first ejection mechanism and the ejection length of the first ejector pin assembly 42.
Step S4 is further provided after step S3, and step S4 is specifically that the pick-up and attachment robot retracts, the second ejector driving unit 51 drives the second ejector pin assembly 52 to retract, the mold locking driving unit drives the movable mold plate 1 to move towards the fixed mold plate 2 until the movable mold plate 1 and the fixed mold plate 2 are attached, and the injection molding machine performs injection and repeats steps S0.2 to S3.
In order to adapt to more application scenarios, step S0.1 is further provided before step S0.2, where step S0.1 specifically includes: the controller identifies the current operating mode, and if the current operating mode is the first thimble assembly and the second thimble assembly linkage mode, the steps S0.2 to S4 are executed.
If the current working mode is the ordinary working mode, the linkage of the first ejector pin assembly 42 and the second ejector pin assembly 52 is not executed, and the ordinary working mode is suitable for in-mold labeling without or after taking a piece first and then labeling. Specifically, the injection molding machine is opened firstly, after the mold is opened in place, the part taking mechanical arm enters between the fixed mold plate 2 and the movable mold plate 1, and the first ejector pin assembly 42 pushes the injection molding part to the part taking mechanical arm.
According to the in-mold labeling method, the ejection and mold opening actions of the first ejection mechanism are performed simultaneously, the injection molding piece is ejected to the side of the fixed mold plate 2, so that the piece taking and labeling mechanical arm can label on the side of the movable mold plate 1 and take the piece on the side of the fixed mold plate 2, the actions on the two sides can be performed simultaneously, the working period of the injection molding machine is shortened, and the working efficiency is improved. Meanwhile, the first ejection mechanism on the side of the movable template 1, the second ejection mechanism on the side of the fixed template 2 and the piece taking and labeling mechanical arm are linked, so that the first ejector pin assembly 42 is returned when the piece taking and labeling mechanical arm performs labeling and piece taking actions, and the first ejector pin assembly 42 can be prevented from colliding with the piece taking and labeling mechanical arm.
