[0027] The utility model is further described below in conjunction with embodiments and drawings.

[0028] like Figure 1-Figure 8 As shown, a fully automatic injection molding system for molding flannel on the surface of an injection molded part mainly includes an injection molding machine 12, an offline conveyor belt 13, a manipulator 14, a flannel lifting workbench 15 and a dual-purpose tooling. The injection molding machine 12 has a fixed mold 12a and a movable mold 12b adapted to the fixed mold 12a. After the movable mold 12b is covered on the fixed mold 12a, the injection molding machine 12 starts injection molding. The flannel lifting workbench 15 is used to feed the flannel, that is, the flannel is placed on the flannel lifting workbench 15 in piles, and the flannel can be gradually lifted to cooperate with the manipulator 14 to drive the dual-purpose tooling to grab it.

[0029] See also Figure 1 and Figure 3 The flannel lifting workbench 15 includes a workbench body 15a, a pallet 15b mounted on the workbench body 15a so as to be able to be raised and lowered, at least one flannel placement tray 15c mounted on the pallet 15b, and a pallet driving mechanism mounted on the workbench body 15a, and the pallet driving mechanism can drive the pallet 15b to rise and fall relative to the workbench body 15a. Each flannel placement tray 15c is stacked with a pile of flannel. As the flannel is grabbed one by one, the pallet driving mechanism gradually raises the pallet 15b, which can facilitate the manipulator 14 to grab the flannel through the dual-purpose tooling, which is simple and reliable.

[0030] The support plate 15b can be installed on the top surface of the workbench body 15a by multiple lifting guide rods 15d, which is simple and reliable. The top surface of the workbench body 15a is installed with an electric lifting device 15e, the upper end of the push rod of the electric lifting device 15e is connected to the bottom surface of the support plate 15b, and the electric lifting device 15e is located at the center of each lifting guide rod 15d. Such a design ensures the stability and reliability of the lifting of the support plate 15b. In addition, the electric lifting device 15e can be a device with a telescopic function driven by a motor such as an electric push rod.

[0031] Furthermore, the top surface of the workbench body 15a is vertically installed with two baffles 15f and two linear guide rails 15g which are relatively arranged on both sides of the support plate 15b. The two linear guide rails 15g are respectively supported on the corresponding baffles 15f, and the bottoms of the two linear guide rails 15g are fixedly connected to the top surface of the workbench body 15a. The support plate 15b is connected to the slides of the two linear guide rails 15g. Through such a design, the lifting and lowering of the support plate 15b is smoother, and the stability and reliability of the lifting and lowering of the support plate 15b are further improved.

[0032] Furthermore, the bottom of the workbench body 15a is also provided with a plurality of universal wheels 15h and a plurality of support legs 15i that can be raised and lowered. When the velvet lifting workbench 15 needs to be moved, the length of each support leg 15i is shortened so that the velvet lifting workbench 15 is supported by each universal wheel 15h, and the velvet lifting workbench 15 can be flexibly moved. After moving to the right position, the length of each support leg 15i is lengthened so that the velvet lifting workbench 15 is supported by each support leg 15i, which is stable and reliable.

[0033] See also Figure 4-Figure 8 The dual-purpose tooling includes a tooling frame 1 and quick-connect joints 2, multiple flannel grabbing mechanisms and multiple pickup mechanisms, all of which are installed on the tooling frame 1, wherein the quick-connect joint 2 is used to connect with the end of the manipulator 14, each flannel grabbing mechanism is arranged on one side of the tooling frame 1 in the thickness direction, and each pickup mechanism is arranged on the other side of the tooling frame 1 in the thickness direction. The manipulator 14 can transfer the dual-purpose tooling between the flannel lifting workbench 15, the movable mold 12b, the fixed mold 12a and the offline conveyor belt 13, so that the dual-purpose tooling can not only grab the flannel on the flannel lifting workbench 15 through each flannel grabbing mechanism and bury it in the movable mold 12b, but also transfer the injection molded injection molded parts from the fixed mold 12a to the offline conveyor belt 13 through each pickup mechanism.

[0034] Therefore, the dual-purpose tooling can not only grasp the flannel through each flannel grasping mechanism, so that the flannel can be transferred to the movable mold 12b through the manipulator 14 in cooperation with the dual-purpose tooling, but also can take out the injection molded parts from the fixed mold 12a through the taking mechanism and transfer them to the offline conveyor belt 13 under the control of the manipulator 14. Therefore, the dual-purpose tooling has a set of dual-purpose functions, which not only reduces the cost of the tooling, but also reduces the replacement frequency of the tooling, improves production efficiency, and saves the storage space of the tooling.

[0035] See also Figure 4-Figure 7 The flannel grabbing mechanism includes a displacement adjusting cylinder 3 and a needle claw grabbing assembly 4 which can approach or move away from the tooling frame 1 along the thickness direction of the tooling frame 1 under the drive of the displacement adjusting cylinder 3, that is, the displacement adjusting cylinder 3 can adjust the position of the needle claw grabbing assembly 4 in the thickness direction of the tooling frame 1.

[0036] The needle claw grabbing assembly 4 includes a needle claw driving cylinder 4a driven by the displacement adjusting cylinder 3, and a positioning rod 4b and a plurality of flannel needles 4c driven by the needle claw driving cylinder 4a. The outer end of the positioning rod 4b extends in a direction away from the tooling frame 1 along the thickness direction of the tooling frame 1, and the flannel needles 4c are distributed circumferentially around the positioning rod 4b. The piston rod of the needle claw driving cylinder 4a can drive the positioning rod 4b and the flannel needles 4c to approach or move away from the tooling frame 1 along the thickness direction of the tooling frame 1.

[0037] When it is necessary to grab the flannel, the positioning rod 4b extends outward under the control of the piston rod of the needle claw driving cylinder 4a and is inserted into the positioning hole of the flannel to position the flannel to be grabbed. At the same time, all the flannel needles 4c extend outward at the same time under the control of the piston rod of the needle claw driving cylinder 4a, and pierce into the flannel to be grabbed, grabbing the flannel like a sharp claw in the figure, thereby grabbing the flannel, and then the flannel can be transported by the manipulator 14 in cooperation with the dual-purpose tooling.

[0038] It should be noted that the thickness of the flannel is relatively thick, usually more than 2 mm, and the flannel needle 4c will not completely pierce the flannel.

[0039] When the flannel needs to be released, the positioning rod 4b retracts inwardly under the control of the piston rod of the needle claw driving cylinder 4a, and exits the positioning hole of the flannel. At the same time, all the flannel needles 4c retreat inwardly at the same time under the control of the piston rod of the needle claw driving cylinder 4a, and no longer pierce the flannel, that is, the positioning rod 4b and all the flannel needles 4c are separated from the flannel.

[0040] Therefore, the dual-purpose tooling can not only reliably position the flannel to be grasped by the positioning rod 4b, and then penetrate the flannel needle 4c into the flannel to be grasped to realize the grasping of the flannel, and then can transport the flannel through the manipulator 14 in cooperation with the tooling; and after the flannel is transported into place, that is, after being buried in the movable mold 12b, the piston rod of the cylinder 3 can be driven by the needle claw to make the positioning rod 4b and each flannel needle 4c retract synchronously, separate from the flannel, and complete the flannel placement action.

[0041] Furthermore, the distance between each flannel needle 4c and the adjacent positioning rod 4b gradually increases from the inside to the outside. That is, the outer end of each flannel needle 4c is inclined outward. Such a design can not only improve the reliability of the flannel needle 4c after piercing the flannel, avoid the flannel falling off, but also reduce the piercing depth of the flannel needle 4c to avoid piercing the flannel.

[0042] Furthermore, the flannel needles 4c are evenly distributed along the circumference of the adjacent positioning rods 4b, thereby further improving the reliability of the flannel needles 4c after piercing the flannel.

[0043] In this embodiment, the outer ends of the positioning rods 4b are provided with positioning heads 4b1, and the outer peripheral surface of the positioning heads 4b1 protrudes from the outer peripheral surface of the positioning rods 4b in the circumferential direction. That is, the width of the positioning heads 4b1 is greater than the width of the positioning rods 4b, which can reduce the interference between the positioning rods 4b and the flannel, so that the flannel can be separated more easily when the flannel is separated.

[0044] There are two embodiments of the installation structure of the flannel grabbing mechanism:

[0045] Installation structure embodiment 1 of the flannel grabbing mechanism:

[0046] See also Figure 4-Figure 6 The displacement adjustment cylinder 3 can be adjustably mounted on the tooling frame 1 through the first mounting plate 7, which is simple and reliable.

[0047] Installation structure embodiment 2 of the flannel grabbing mechanism:

[0048] See also Figure 4 , Figure 5 and Figure 7 The displacement adjusting cylinder 3 is installed on the slide of the slide cylinder 9 through the second mounting plate 8. The slide cylinder 9 is adjustably mounted on the tooling frame 1 through the third mounting plate 10, and the extension direction of the slide cylinder 9 is perpendicular to the extension direction of the corresponding displacement adjusting cylinder 3, so that the position of the needle claw grabbing assembly 4 can be adjusted by the slide cylinder 9 to realize the tensioning action of the flannel cloth.

[0049] Specifically, the installation structure of the flannel grabbing mechanism of one part of the dual-purpose tooling adopts embodiment 1, and the installation structure of the flannel grabbing mechanism of the other part adopts embodiment 2, especially the installation structure of the flannel grabbing mechanism at the corners of the tooling frame 1 adopts embodiment 2, and the installation structure of the flannel grabbing mechanism in the middle position of the tooling frame 1 adopts embodiment 1, so that after grabbing the flannel, the position of the slide cylinder 9 is adjusted (usually the needle claw grabbing assembly 4 is adjusted to a farther position) to achieve tensioning of the flannel, thereby avoiding the problem of the flannel falling off during transportation.

[0050] Part of the displacement adjusting cylinder 3 is adjustably mounted on the tooling frame 1 through the first mounting plate 7, and the other part of the displacement adjusting cylinder 3 is mounted on the slide of the slide cylinder 9 through the second mounting plate 8. The slide cylinder 9 is adjustably mounted on the tooling frame 1 through the third mounting plate 10, and the extension direction of the slide cylinder 9 is perpendicular to the extension direction of the corresponding displacement adjusting cylinder 3.

[0051] See also Figure 4-Figure 7 The tooling frame 1 is assembled from a number of profiles, and the profiles have a plurality of bolt connection grooves 1a extending along their length direction on the circumference thereof. The first mounting plate 7 and the third mounting plate 10 are both bolted and installed in the corresponding bolt connection grooves 1a so that the bolt connectors can be locked or unlocked. Thus, the installation positions of the first mounting plate 7 and the third mounting plate 10 on the tooling frame 1 can be flexibly adjusted to adapt to flannels of different sizes, thereby improving the versatility of the dual-purpose tooling.

[0052] Furthermore, the first mounting plate 7 and the third mounting plate 10 are provided with both circular holes a matched with the bolt connectors and arc holes b matched with the bolt connectors, so that the installation position of the flannel grabbing mechanism can be rotated to adjust the adjustment, with greater adjustment flexibility and better versatility.

[0053] Furthermore, a triangular reinforcement plate 11 is installed between at least some of the adjacent profiles, thereby effectively improving the structural strength of the tooling frame 1 and improving the impact resistance.

[0054] See also Figure 4 , Figure 5 and Figure 8 The picking mechanism includes a suction cup 5 and a suction cup adjustment assembly 6 connected between the suction cup 5 and the tooling frame 1, and the outer end of the suction cup 5 extends in a direction away from the tooling frame 1 along the thickness direction of the tooling frame 1.

[0055] Therefore, the taking-up mechanism can take out the injection molded parts by vacuum adsorption of the suction cup 5, and then the injection molded parts can be transferred to the offline conveyor belt 13 offline by the robot 14 in cooperation with the tooling, which is simple and reliable.

[0056] Furthermore, the suction cup adjustment assembly 6 includes a connecting rod mounting seat 6e, a first cross connecting seat 6a, a second cross connecting seat 6b, and a first connecting rod 6c and a second connecting rod 6d that are perpendicular to each other. The connecting rod mounting seat 6e can be locked or unlocked and installed in the corresponding bolt connecting groove 1a through a bolt connecting piece. The two ends of the first connecting rod 6c can be rotatably and telescopically adjusted on the connecting rod mounting seat 6e and the first cross connecting seat 6a, respectively. The two ends of the second connecting rod 6d can be rotatably and telescopically adjusted on the first cross connecting seat 6a and the second cross connecting seat 6b, respectively. The base 5a of the suction cup 5 is respectively installed on the corresponding second cross connecting seat 6b.

[0057] Therefore, the suction cup adjustment component 6 can adjust its own shape with multiple degrees of freedom, thereby achieving multiple degrees of freedom adjustment of the suction cup 5, thereby adapting to injection molded parts of different shapes and structures, and having excellent versatility.

[0058] See also Figure 1 In this embodiment, the manipulator 14 not only has the functions of two-dimensional translation and lifting adjustment, but also the end of the manipulator 14 can be rotated and adjusted, which improves flexibility.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
