[0094] When in use, the injection molding material is placed in the mixing barrel 602, and the fifth driving member 603 is started to extrude the injection molding material in the mixing barrel 602 and mix it in the plastic hose; the mixed injection molding material is extruded along the flexible injection head 604, and the gap between the thermoplastic shell 01 and the continuous fiber reinforced layer 02, and the gap between the continuous fiber reinforced layer 02 and the wear-resistant structural member 03 are injection molded and filled in turn, thereby completing the molding of the fiber reinforced structural member.
[0095] Furthermore, the gripping assembly 500 includes a fourth driving member 501 , a mechanical claw 502 , and an identification module 503 ;
[0096] The fourth driving member 501 is connected to the side wall of the frame 100, and the mechanical claw 502 is connected to the output end of the fourth driving member 501;
[0097] The identification module 503 is connected to the fourth driving member 501 and is disposed on the side of the mechanical claw 502 ; the identification module 503 can identify the position of the flexible injection head 604 of the injection molding component 600 .
[0098] In one embodiment of the present invention, Figure 1 As shown, the fourth driving member 501 is a six-degree-of-freedom robotic arm, which can control the movement of the mechanical claw 502, and with the cooperation of the identification module 503, the mechanical claw 502 can grab or release the wear-resistant structural part 03; the mechanical claw 502 can place the wear-resistant structural part 03 at a specified position; the mechanical claw 502 can pull the flexible injection head 604 to the injection molding port of the structural part; the fourth driving member 501 is a driving motor; when in use, the driving motor is started, the mechanical claw 502 grabs the wear-resistant structural part 03 on the side of the frame 100, and places it at the specified position of the positioning member 05; then, the third driving member 203 is started to transport the molding platform 401 to the bottom of the printing component 300, and the printing component 300 continues to print the thermoplastic material 06 to realize the packaging of the wear-resistant structural part 03; after the packaging is completed, the third driving member 203 is started again to transport the molding platform 401 to the bottom position of the injection molding component 600.
[0099] The clamping assembly 500 realizes the clamping of the wear-resistant structural part 03 and the flexible injection head 604. Under the coordination of the mechanical melon 502 and the identification module 503, the wear-resistant structural part 03 is embedded in the specified position of the structural part; the flexible injection head 604 of the injection molding assembly 600 is pulled to the injection molding port of the structural part.
[0100] The recognition module includes a sensor, a camera and an image processing controller. The image processing controller is a PLC controller. The PLC controller is electrically connected to the sensor and the fourth driving member 501 respectively.
[0101] The PLC controller is fixed to the mounting base of the fourth driving member 501 by means of bolts, and the sensor and the camera are connected to the fourth driving member 501 by means of screws.
[0102] Since the flexible injection head 604 of the injection molding assembly 600 is a soft injection molding tube, the mechanical claw 502 needs to determine the position of the injection molding tube in order to place the wear-resistant structural component 03 at the correct position.
[0103] When in use, the sensor and the camera can identify the position of the injection tube, and then send the sensing signal to the PLC controller. The PLC controller controls the moving position of the mechanical claw 502 through the fourth driving member 501, and pulls the flexible injection head 604 to the injection port of the structural part.
[0104] In one embodiment of the present invention, Figure 7As shown, it is a schematic diagram of a continuous fiber reinforced structural part embedded with a metal structural part manufactured by the device of the present invention. The specific working process of the whole device is as follows: the printing component 300, driven by the driving component 200, prints the thermoplastic shell 01, the continuous fiber reinforced layer 02 and the positioning piece 05 of the thermoplastic material on the forming platform 401 respectively. When the printing is consistent with the height of the wear-resistant structural part 03, that is, the metal structural part, the clamping component 500 clamps the metal structural part to be embedded from the metal structural part placement box and places it on the positioning piece 05 of the thermoplastic material. After the placement is completed, the thermoplastic material extrusion mechanism of the printing component 300 continues to print the thermoplastic material 06 to form a closed cavity for accommodating the injection layer 04. After the printing is completed, the clamping component 500 pulls the flexible injection head 604 of the injection molding component 600 to the injection molding port to complete the injection molding. After the injection molding part is solidified, the positioning piece 05 is removed to obtain the required structural part.
[0105] In one embodiment of the present invention, Figure 8 As shown, a schematic diagram of a continuous fiber reinforced structural part without a metal structural part manufactured by the device of the present invention, the specific working process of the whole device is as follows: the printing component 300, driven by the driving component 200, prints the thermoplastic shell 01 and the continuous fiber reinforced layer 02 on the forming platform 401 respectively, and the thermoplastic material extrusion mechanism of the printing component 300 continues to print the thermoplastic material to form a closed cavity accommodating the injection layer 04. After printing, the clamping component 500 pulls the flexible injection head 604 of the injection molding component 600 to the injection molding port to complete the injection molding. After the injection molding part is solidified, the desired structural part is obtained.
