Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a dual-purpose tool for grabbing and taking out flannel. Background Art

[0002] Please refer to the Chinese utility model patent with publication number CN220741956U. Some injection molded parts need to be formed with a layer of velvet on the surface to improve the surface touch and high-end appearance of the injection molded parts.

[0003] At present, the flannel is first manually buried in the movable mold of the injection mold, and then the mold is closed and injection molding is performed to obtain an injection molded part with the flannel formed on the surface.

[0004] In the above process, due to the fact that the flannel is a flexible material, there are problems with the existing tooling structure design. The robot cannot use the existing tooling to realize the automatic placement and transportation of the flannel, and can only be operated manually, which affects the degree of automation of the entire production equipment.

[0005] Solving the above problems has become a top priority. Utility Model Content

[0006] In order to solve the technical problem that there is currently no tooling that can cooperate with a manipulator to realize the automatic placement and transportation of flannel, the utility model provides a dual-purpose tooling for grabbing and taking flannel.

[0007] The technical solution is as follows:

[0008] The first aspect of the present application relates to a dual-purpose tool for flannel grabbing and taking out items, comprising a tool frame and a quick-connect joint arranged on the tool frame, characterized in that: a plurality of flannel grabbing mechanisms and a plurality of item taking mechanisms are respectively arranged on both sides of the tool frame in the thickness direction;

[0009] The flannel grabbing mechanism includes a displacement adjustment cylinder and a needle claw grabbing assembly that can approach or move away from the tooling frame along the thickness direction of the tooling frame under the drive of the displacement adjustment cylinder, the needle claw grabbing assembly includes a needle claw driving cylinder driven by the displacement adjustment cylinder and a positioning rod and a plurality of flannel needles that are driven by the needle claw driving cylinder, the outer end of the positioning rod extends in the direction away from the tooling frame along the thickness direction of the tooling frame, the flannel needles are circumferentially distributed around the positioning rod, and the piston rod of the needle claw driving cylinder can drive the positioning rod and the flannel needles to approach or move away from the tooling frame along the thickness direction of the tooling frame;

[0010] The picking mechanism comprises a suction cup and a suction cup adjustment assembly connected between the suction cup and the tooling frame, and the outer end of the suction cup extends in a direction away from the tooling frame along the thickness direction of the tooling frame.

[0011] By adopting the above dual-purpose tooling for grabbing and removing flannel, not only can the flannel to be grabbed be positioned by the positioning rod first, and then the flannel needle can be inserted into the flannel to be grabbed to realize the grabbing of the flannel, and then the flannel can be transferred by the robot arm in cooperation with the tooling; and after the flannel is transferred into place, the piston rod of the cylinder can be driven by the needle claw to make the positioning rod and each flannel needle retract synchronously and separate from the flannel to complete the placement of the flannel; at the same time, the removal mechanism can also realize the action of removing the injection molded parts by vacuum adsorption of the suction cup, and then the injection molded parts can be transferred off the line by the robot arm in cooperation with the tooling; 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 the production efficiency, and saves the storage space of the tooling.

[0012] In some embodiments, the distance between each velvet needle and the adjacent positioning rod gradually increases from the inside to the outside.

[0013] In some embodiments, the outer ends of the positioning rods each have a positioning head, and the outer circumferential surface of the positioning head protrudes from the outer circumferential surface of the positioning rod along the circumferential direction.

[0014] In some embodiments, some of the displacement adjusting cylinders are adjustably mounted on the tooling frame via a first mounting plate, and other parts of the displacement adjusting cylinders are mounted on the slide of the slide cylinder via a second mounting plate.

The connecting rod mounting seat can be locked or unlocked in the corresponding bolt connecting groove through a bolt connecting piece.

[0023] The utility model is further described below in conjunction with embodiments and drawings.

[0024] like Figure 1-Figure 5 As shown, a dual-purpose tool for flannel grabbing and picking up items mainly comprises a tool frame 1, a quick-connect joint 2, a plurality of flannel grabbing mechanisms and a plurality of picking up mechanisms, and the quick-connect joint 2, the plurality of flannel grabbing mechanisms and the plurality of picking up mechanisms are all mounted on the tool frame 1. The quick-connect joint 2 is used to connect with a manipulator, each flannel grabbing mechanism is mounted on one side of the tool frame 1 in the thickness direction, and each picking up mechanism is mounted on the other side of the tool frame 1 in the thickness direction.

[0025] Therefore, the dual-purpose tooling of this embodiment can not only realize the grasping of the flannel through each flannel grasping mechanism, so that the flannel can be transferred to the injection mold through the manipulator in cooperation with the dual-purpose tooling, but also can take out the injection molded parts through the taking mechanism, and then the injection molded parts can be transferred off the production line through the manipulator in cooperation with the tooling. 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.

[0026] See also Figure 1-Figure 4 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.

[0027] 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.

[0028] 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 penetrate 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 in cooperation with the dual-purpose tooling.

[0029] 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.

[0030] Therefore, the dual-purpose tool 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 by the robot arm in cooperation with the tool; and after the flannel is transported into place, 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 and separate from the flannel, thereby completing the placement of the flannel.

[0031] 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, and this design can improve the reliability of the flannel needle 4c after piercing the flannel, and avoid the problem of the flannel falling off.

[0032] 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.

[0033] 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.

[0034] There are two embodiments of the installation structure of the flannel grabbing mechanism:

[0035] Installation structure embodiment 1 of the flannel grabbing mechanism:

[0036] See also Figure 1-Figure 3 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.

[0037] Installation structure embodiment 2 of the flannel grabbing mechanism:

[0038] See also Figure 1 , Figure 2 and Figure 4 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.

[0039] 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.

[0040] 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.

[0041] See also Figure 1-Figure 4 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.

[0042] 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.

[0043] 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.

[0044] See also Figure 1 , Figure 2 and Figure 5 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.

[0045] 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 off the production line by the robot in cooperation with the tooling, which is simple and reliable.

[0046] 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.

[0047] 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.

[0048] 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.
