Description

Technical Field

[0001] This utility model relates to the field of material handling technology, and in particular to a material handling device for annular injection molded parts. Background Technology

[0002] Injection molded parts refer to various plastic or rubber products made from thermoplastic or thermosetting materials using plastic molding molds. Currently, after injection molded parts are formed in the mold, when the mold is opened to remove the parts, due to the high temperature of the injection molded parts, most manufacturers use robotic grippers to remove them to avoid burns and safety hazards during manual removal. However, because the specifications and shapes of the produced injection molded parts vary, and some parts have uneven surfaces, robotic grippers are not suitable for adapting to and holding injection molded parts of different shapes, and parts are prone to detaching from the grippers. Therefore, the existing material removal structure for injection molded parts is not stable and needs improvement.

[0003] The above-mentioned existing technical solutions have the following defects: the traditional gripper design may result in uneven distribution of clamping force on the injection molded parts due to insufficient structural precision, which may easily cause the parts to deform or fall off; the gripper bracket of the traditional material handling device is not precise enough in adjusting its position. Utility Model Content

[0004] The purpose of this invention is to provide a ring-shaped injection molded part feeding device to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A ring-shaped injection molded part feeding device includes a position adjustment module. The position adjustment module includes two sets of support rods, a first slider, a second slider, a third slider, and a connecting rod. The top of the support rod is provided with a first slide rail. The first slider is slidably mounted on the first slide rail and the sliding direction of the first slider is back-to-back. The front part of the first slider is provided with a second slide rail. The second slider is slidably mounted on the second slide rail and the sliding direction of the second slider is left-to-right. The right part of the second slider is provided with a third slide rail. The third slider is slidably mounted on the third slide rail and the sliding direction of the third slider is up-down. The connecting rod is fixedly installed at the bottom of the third slider. The material handling head is movably installed at the bottom of the connecting rod. The material handling head includes an L-shaped connecting plate, a mounting plate, and a semi-circular gripper. The mounting plate is fixedly installed on the left side of the vertical part of the L-shaped connecting plate, and the semi-circular gripper is fixedly installed on the left side of the mounting plate.

[0006] By adopting the above technical solution, the position adjustment module, through the cooperation of the support rod, the first slider, the second slider, the third slider, the first slide rail, the second slide rail, and the third slide rail, becomes a three-degree-of-freedom position adjustment module, solving the problem of insufficient position adjustment accuracy. The material handling head includes an L-shaped connecting plate, a mounting plate, and a semi-circular gripper. Instead of using traditional gripping, the material handling head places the injection molded part on the semi-circular gripper, solving the problem of part deformation caused by uneven clamping force during the clamping process of ordinary clamps.

[0007] In a further embodiment, the interior of the third slider and the connecting rod is hollow, a driving device is fixedly installed inside the third slider, a driving rod is slidably installed inside the connecting rod, and a rectangular opening is provided at the bottom end of the connecting rod.

[0008] In a further embodiment, the bottom end of the drive rod is connected to the L-shaped connecting plate via a transmission block, and the front and rear ends of the rectangular opening of the connecting rod are fixedly mounted with rotating shafts, and the L-shaped connecting rod is rotatably mounted on the rotating shafts.

[0009] In a further embodiment, the distance between the front and rear ends of the L-shaped connecting plate is greater than the distance between the front and rear ends of the rectangular opening.

[0010] By adopting the above technical solution, the L-shaped connecting plate rotates around the pivot under the drive of the drive rod. The distance between the front and rear ends of the L-shaped connecting plate is greater than the distance of the rectangular opening, which limits the rotation angle of the L-shaped connecting plate.

[0011] In a further embodiment, the surfaces of the first slide rail, the second slide rail, and the third slide rail are provided with friction damping pads.

[0012] By adopting the above technical solution, the friction damping pad makes the position adjustment more stable through friction energy dissipation.

[0013] In a further embodiment, a silicone sleeve is fitted over the middle of the semi-circular gripper head, and limiting protrusions are provided at the top and bottom ends of the semi-circular gripper head, and the central angle of the semi-circular gripper head is less than 90 degrees.

[0014] In a further embodiment, the design of the silicone sleeve in the middle of the semi-circular gripper head and the limiting protrusions at the top, bottom and tail ends ensures that the material will not fall before reaching the designated position when the device picks up the material, and the design of the central angle of the semi-circular gripper head being less than 90 degrees prevents the problem of material jamming when placing the material.

[0015] In summary, this utility model has the following beneficial effects: 1. The position adjustment module, with its multiple sliders and rails, enables multi-angle and multi-directional position adjustment. The pick-up head structure allows for placement instead of gripping, preventing part deformation caused by uneven clamping force. The friction damping pads provide greater stability during position adjustment through energy dissipation. The semi-circular gripper silicone sleeve and limiting protrusions prevent parts from falling before reaching their designated location. Attached Figure Description
