Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a lower shell for the forearm of a robotic arm. Background Technology

[0002] A robotic arm is an automated device that mimics the structure and function of a human arm. It achieves precise operation through the coordinated movement of multiple joints and is widely used in industrial manufacturing, medical care, logistics, scientific research and other fields.

[0003] When the robotic arm is working, the actuator at the end of the robotic arm and each connecting arm of the robotic arm need to move. Therefore, a driver needs to be installed on the connecting arm to drive it. However, the setting of the driver makes the connecting arm heavy.

[0004] A search revealed, for example, Chinese patent application CN212825480U, which discloses a cardboard gripping mechanism and robotic arm. This mechanism allows the robotic arm to remove stacked workpieces of a certain thickness from a pile without damage and transfer them to the next process. The included lifting plate device raises part of the workpiece before the clamping plate is inserted, creating a larger gap and preventing damage to the paper workpiece during clamping. It can also be used to push the workpiece. In a preferred embodiment, the upper and lower arms employ a tubular structure, combined with a clamping plate made of carbon fiber plate, which significantly reduces the weight of the robotic arm, thereby increasing the weight of the workpiece that can be transferred each time.

[0005] However, when using the above solution, although the upper and lower arms of the component structure, together with the clamping plate made of carbon fiber plate, can greatly reduce the weight of the robot, the wiring of the driver needs to be organized inside the lower shell of the robot arm. When organizing the wiring, the volume inside the lower shell of the forearm cannot be guaranteed to be large enough, resulting in an unsightly and inconvenient wiring arrangement. Utility Model Content

[0006] Therefore, this utility model provides a lower shell for the forearm of a robotic arm to solve the problem of inconvenient wiring of the driver circuit caused by insufficient internal volume of the robotic arm in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A lower housing for the forearm of a robotic arm includes a lower housing body. The outer wall of the lower housing body is symmetrically provided with first heat dissipation vents, and the bottom of the lower housing body is provided with a through groove. The inside of the through groove is provided with a first cable management device, which is used to manage the driver circuitry while taking into account heat dissipation of the circuitry.

[0010] The inside of the through slot is also equipped with a second cable management device for managing the driver circuitry.

[0011] In a preferred embodiment, the outer wall of the main body of the first cable management device is symmetrically provided with second heat dissipation vents, and the shape of the second heat dissipation vents is adapted to the shape of the first heat dissipation vents.

[0012] In a preferred embodiment, the cable management mechanism includes a main body that is snapped into a slot, a plurality of first cable management slots being formed on the top of the main body, a plurality of extension plates being equidistantly arranged on the outer wall of the main body, and a plurality of second cable management slots being formed on the top of the extension plates.

[0013] In a preferred embodiment, a dustproof net is provided at the bottom of the main body of the first cable management device.

[0014] In a preferred embodiment, a third cable management groove is provided at the center of both ends of the outer wall of the first cable management device body, and a first limiting block is provided between the third cable management groove and the middle first cable management groove, and the first limiting block is engaged with the top of the first cable management device body.

[0015] In a preferred embodiment, the second cable management device includes a second cable management device body that is bolted to the bottom of the lower shell body. The bottom of the second cable management device body has a plurality of horizontal plates arranged horizontally, and the interior of the second cable management device body has a longitudinal plate arranged vertically.
