Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of polymer material processing equipment, and in particular to a dual-arm robotic arm for the production of non-standard plastic parts. Background Technology
[0002] Plastic products refer to a general term for various products made from plastics, which are mainly synthetic or natural resins, through specific processing techniques such as injection molding, extrusion, and blow molding. Their core characteristics are material plasticity, processing fluidity, and morphological stability at room temperature.
[0003] The main component of plastic products is resin, which generally accounts for 40%-100% of the total composition. It is typically a high-molecular-weight organic polymer, such as polyethylene (PE) and polypropylene (PP). Resin can melt or flow during processing, giving plastics its plasticity. In addition, plastics contain additives, such as plasticizers, stabilizers, and colorants, to improve properties such as abrasion resistance, corrosion resistance, and insulation, or to meet other specific application requirements.
[0004] Based on this, Chinese patent CN117885308A discloses an injection control device that changes the method of driving the injection push rod via an oil pump to driving the injection push rod via an injection control device. The oil pump drives the first piston, which in turn drives the second piston. The second piston drives the hydraulic oil in the fourth cavity into the injection drive oil circuit, which in turn drives the injection push rod. The injection push rod then drives the material to be injected into the mold. Because the piston area of the second piston is larger than that of the first piston, hydraulic oil can be injected into the first cavity at the same working power as the original oil pump, while the amount of hydraulic oil in the fourth cavity that is forced into the injection drive oil circuit is greater than the amount of hydraulic oil in the first cavity. This achieves rapid injection; moreover, the working power of the original oil pump motor unit remains unchanged or is reduced, maintaining the same power consumption as before, without increasing processing costs.
[0005] However, existing plastic product molding processes suffer from insufficient material handling efficiency. Specifically, after plastic products are molded and ejected from the mold, they typically need to be manually removed by workers and placed in designated turnover boxes or blister trays for subsequent processing. The temperature of plastic products immediately after demolding is still very high; for example, the demolding temperature for nylon is between 80-100℃, for ABS between 60-80℃, and for PC even between 100-120℃. Therefore, manual handling of demolded parts easily leads to burns and other safety accidents. Existing technologies also use suction cups for adsorption and then robotic arms for material handling; however, for non-standard or irregularly shaped plastic parts, it is difficult to find a suitable adsorption surface for the suction cups, resulting in insufficient efficiency in automated material handling.

[0010] Furthermore, the linear guide is located adjacent to the rodless cylinder on the side of the hanger, and the auxiliary slider is movably connected to the linear guide.
[0011] Furthermore, the two stop structures are positioned opposite each other at both ends of the hanger, and the auxiliary slider is movably positioned between the two stop structures. The movable connecting block is connected to the vertical cylinder actuation mechanism.
[0012] Furthermore, the vertical cylinder actuation mechanism includes a vertical drive cylinder, a vertical piston rod, and a vertical moving block.
[0013] Furthermore, the vertical drive cylinder is disposed on the side of the movable connecting block, the vertical drive cylinder is drivenly connected to the vertical piston rod, one end of the vertical piston rod is connected to the vertical movable block, and the clamping cylinder drive mechanism is connected to the vertical movable block.

The two sets of actuation mechanisms can work alternately; when one clamps and ejects a plastic part, the other performs the unloading operation on the clamped plastic part.

Therefore, this utility model of a dual-arm robotic arm for producing non-standard plastic parts solves the technical problem of how to improve the unloading efficiency of non-standard plastic parts.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0027] Please refer to the following: Figures 1 to 3 This utility model discloses a dual-arm robotic arm for the production of non-standard plastic parts, comprising: a support frame 1, a hanger 2, a rodless cylinder actuation mechanism 3, a vertical cylinder actuation mechanism 4, a clamping cylinder drive mechanism 5, and a gripper structure 6. A hanger 2 is provided on each of the upper two sides of the support frame 1, and a rodless cylinder actuation mechanism 3 is provided on the side of each hanger 2. A vertical cylinder actuation mechanism 4 is provided on the side of each rodless cylinder actuation mechanism 3, and each rodless cylinder actuation mechanism 3 is driven and connected to a corresponding vertical cylinder actuation mechanism 4. A clamping cylinder drive mechanism 5 is provided below each vertical cylinder actuation mechanism 4, and each vertical cylinder actuation mechanism 4 is driven and connected to a corresponding clamping cylinder drive mechanism 5. A gripper structure 6 is driven and connected to the lower part of each clamping cylinder drive mechanism 5.
[0028] Specifically, when the dual-arm robotic arm for non-standard plastic parts production of this utility model is in operation, after the molded plastic part is ejected by the mold ejection mechanism, the rodless cylinder actuation mechanism 3 first drives the corresponding vertical cylinder actuation mechanism 4 to above the ejected plastic part; then, the vertical cylinder actuation mechanism 4 drives the clamping cylinder drive mechanism 5 together with the gripper structure 6 to descend until the ejected plastic part is within the clamping range of the gripper structure 6; then, the clamping cylinder drive mechanism 5 drives the gripper structure 6 to clamp the edge of the ejected plastic part. Afterwards, the vertical cylinder actuation mechanism 4 drives the clamping cylinder drive mechanism 5 and the gripper structure 6 to ascend to a preset position, and the rodless cylinder actuation mechanism 3 then drives the vertical cylinder actuation mechanism 4 to move the clamped plastic part onto the turnover box / cargo blister tray, where the clamping cylinder drive mechanism 5 drives the gripper structure 6 to release the plastic part to the preset position. In the technical solution of the dual-arm manipulator for non-standard plastic parts production of this utility model, a set of hangers 2, a rodless cylinder action mechanism 3, a vertical cylinder action mechanism 4, a clamping cylinder drive mechanism 5, and a gripper structure 6 are respectively arranged on the two sides of the support frame 1. The two sets of action mechanisms can work alternately. When one clamps and ejects the plastic part, the other performs the unloading operation on the clamped plastic part. This can improve the automated unloading efficiency of the ejected plastic part. Moreover, the dual-arm manipulator for non-standard plastic parts production of this utility model abandons the method of suction cup to pick up the plastic part and adopts grippers to hold the edge of the plastic part. This can ensure that the non-standard plastic part can be stably clamped and transported, thereby significantly improving the unloading efficiency of non-standard plastic parts.
[0029] Furthermore, the rodless cylinder actuation mechanism 3 includes a rodless cylinder 301, a piston slider 302, a movable connecting block 303, an auxiliary slider 304, a linear guide 305, and a stop structure 306. The rodless cylinder 301 is disposed on the side of the hanger 2, and the piston slider 302 is driven and connected to the rodless cylinder 301. The movable connecting block 303 is disposed on the side of the piston slider 302, and the auxiliary slider 304 is disposed adjacent to the piston slider 302 on the side of the movable connecting block 303. The linear guide 305 is disposed adjacent to the rodless cylinder 301 on the side of the hanger 2, and the auxiliary slider 304 is movably connected to the linear guide 305. The two stop structures 306 are disposed opposite to each other at the two ends of the hanger 2, and the auxiliary slider 304 is movably disposed between the two stop structures 306. The movable connecting block 303 is connected to the vertical cylinder actuation mechanism 4.
[0030] Specifically, the two ends of the rodless cylinder 301 are connected to an external air source. When the external air source inputs gas to the left or right end of the rodless cylinder 301, the rodless cylinder 301 can drive the piston slider 302 to move to the right or left. This, in turn, causes the piston slider 302 to move the movable connecting block 303 to move to the right or left. Furthermore, the movable connecting block 303 causes the vertical cylinder actuation mechanism 4 to move to the right or left. Further, an auxiliary slider 304 is also connected to the side of the movable connecting block 303. The auxiliary slider 304 is movably connected to the linear guide 305, thereby making the left-right reciprocating motion of the movable connecting block 303 smoother. Moreover, the stop structure 306 can control the left and right limits of the movable connecting block 303 by abutting and limiting the left and right ends of the auxiliary slider 304.
[0031] Furthermore, the vertical cylinder actuation mechanism 4 includes a vertical drive cylinder 401, a vertical piston rod 402, and a vertical moving block 403; the vertical drive cylinder 401 is disposed on the side of the movable connecting block 303, the vertical drive cylinder 401 is drivenly connected to the vertical piston rod 402, one end of the vertical piston rod 402 is connected to the vertical moving block 403, and the clamping cylinder drive mechanism 5 is connected to the vertical moving block 403.
[0032] Specifically, the vertical drive cylinder 401 is connected to an external air source, so that the vertical drive cylinder 401 can drive the vertical piston rod 402 to extend or retract under the power of the external air source; and when the vertical piston rod 402 moves, it can drive the vertical moving block 403 to move downward or upward; thus, the vertical moving block 403 drives the clamping cylinder drive mechanism 5 to move downward or upward.
[0033] Furthermore, the clamping cylinder drive mechanism 5 includes a clamping cylinder connecting block 501, a clamping cylinder 502, and a swing piston rod 503; the clamping cylinder connecting block 501 connects the vertical moving block 403 and the clamping cylinder 502 respectively, and the two swing piston rods 503 are movably disposed in the clamping cylinder 502; one end of each swing piston rod 503 is correspondingly connected to a gripper structure 6.
[0034] Specifically, the clamping cylinder 502 is connected to an external air source. When the external air source is used as a power input to the clamping cylinder 502, the clamping cylinder 502 can drive the two swing piston rods 503 to move closer to each other or move away from each other. Thus, the two gripper structures 6 can move closer to each other to clamp the workpiece or move away from each other to release the workpiece.
[0035] Furthermore, the gripper structure 6 has a claw 601 and a foam pad 602; the claw 601 is connected to one end of the swing piston rod 503, and the foam pad 602 is disposed on the side of one end of the claw 601. Specifically, the foam pad 602 can prevent damage to the appearance surface of the plastic part when gripping it.
[0036] In summary, the dual-arm robotic arm for non-standard plastic parts production of this utility model is provided with a support frame 1, a hanger 2, a rodless cylinder actuation mechanism 3, a vertical cylinder actuation mechanism 4, a clamping cylinder drive mechanism 5, and a gripper structure 6. A hanger 2 is provided on each of the upper two sides of the support frame 1, and a rodless cylinder actuation mechanism 3 is provided on the side of each hanger 2. A vertical cylinder actuation mechanism 4 is provided on the side of each rodless cylinder actuation mechanism 3, and each rodless cylinder actuation mechanism 3 is correspondingly driven and connected to a vertical cylinder actuation mechanism 4. A clamping cylinder drive mechanism 5 is provided below each vertical cylinder actuation mechanism 4, and each vertical cylinder actuation mechanism 4 is correspondingly driven and connected to a clamping cylinder drive mechanism 5. A gripper structure 6 is correspondingly driven and connected to the lower part of each clamping cylinder drive mechanism 5. In the technical solution of this utility model of a dual-arm robotic arm for producing non-standard plastic parts, a set of hangers 2, a rodless cylinder actuation mechanism 3, a vertical cylinder actuation mechanism 4, a clamping cylinder drive mechanism 5, and a gripper structure 6 are respectively arranged on the two sides of the support frame 1. The two sets of actuation mechanisms can work alternately; when one clamps and ejects a plastic part, the other performs a material unloading operation on the clamped plastic part. This improves the automated unloading efficiency of the ejected plastic part. Moreover, this utility model of a dual-arm robotic arm for producing non-standard plastic parts abandons the suction cup method of picking up plastic parts and adopts grippers to hold the edge of the plastic part, thereby ensuring that the non-standard plastic part can be stably clamped and transported, thus significantly improving the unloading efficiency of non-standard plastic parts. Therefore, this utility model of a dual-arm robotic arm for producing non-standard plastic parts solves the technical problem of how to improve the unloading efficiency of non-standard plastic parts.
[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
