Description

Technical Field

[0001] The utility model relates to the technical field of a cylinder connection assembly for a mechanical arm, in particular to a cylinder connection assembly for a mechanical arm. Background Art

[0002] At present, in the process of producing semiconductors, several processing steps are required. In the semiconductor back-end equipment, the robot arm equipped with a cylinder plays an important role. The output end of the cylinder is equipped with a suction cup, so as to cooperate with the control of the robot arm to undertake the task of grabbing and carrying semiconductor chips. The cylinder and the robot arm are generally installed and fixed by connecting parts to fill the missing parts of the processed product in its shape and performance, so as to better complete the matching between the processed product and the industrial production equipment.

[0003] However, the existing cylinder connector structure is relatively simple, and most of them are one-piece structures. Although they can enhance the rigidity of the connector to a certain extent, such a structure also makes it difficult to maintain it later. For example, some easily worn parts on the connector, such as mounting holes, positioning pins, connecting seats, etc., when these parts are worn out and need to be replaced, the current solution is to replace the connector as a whole. This undoubtedly greatly increases the equipment maintenance cost of the processing enterprise and also causes a waste of resources to a certain extent.

[0004] At the same time, the existing connecting parts generally have multiple mounting holes on the side wall, and are then fixed together with the connecting seat of the cylinder with screws, but the positions of the mounting holes are fixed, which is not convenient for corresponding installation changes according to the actual situation of the robot arm, and has great limitations in use. Utility Model Content

[0007] Both ends of the mounting frame are in contact with mounting plates, and a clamping assembly is installed between the mounting frame and the two mounting plates.

[0008] Furthermore, the back side of the mounting frame is symmetrically provided with slide grooves, the inner walls of the two slide grooves are slidably connected with a plurality of sliders, and one end of each two corresponding sliders is fixedly connected to one side of the outer surface of the same mounting seat.

[0009] Furthermore, the snap-on assembly includes a snap block fixedly connected to the back side of the mounting plate, the outer surface of the snap block is snap-on to the inside of the side wall of the mounting frame, and the inside of the side wall of the mounting frame is provided with a snap slot matching the snap block. By snapping the snap block into the slot, the mounting plate can be preliminarily positioned at the end of the mounting frame, which is convenient for subsequent fixation.

[0010] Furthermore, mounting holes are symmetrically opened on one side of the outer surface of the mounting plate, and the inner walls of the two mounting holes are threaded with fastening bolts, and one end of the single fastening bolt close to the side of the mounting frame extends into the inside of the side wall of the mounting frame. The single fastening bolt can fix the mounting plate and the mounting frame, and the other fastening bolt can fix the assembled mounting plate and the mounting frame together to the outer surface of the robotic arm, thereby realizing the installation and fixation of the connecting part and the robotic arm.

[0011] Furthermore, both ends of the mounting frame are provided with additional mounting holes matching the fastening bolts, and the inner walls of the two mounting holes are respectively threadedly connected to one end of the corresponding fastening bolts, that is, the inner walls of the mounting holes should be provided with threads, which are screwed together with the outer threads of the fastening bolts through the internal threads.

[0012] Furthermore, a connecting plate is fixedly connected to the upper surface of the mounting frame, and a handle is fixedly connected to the front side of the connecting plate. By holding the handle, the mounting frame can be controlled by controlling the connecting plate, so that the mounting frame can be picked up and placed at a suitable installation position of the robotic arm.

[0013] Furthermore, the outer surface of the handle is provided with a plurality of anti-skid grooves, and the presence of the anti-skid grooves can increase the friction of the handle so that the staff will not slip easily when holding the handle.

[0014] The utility model has the following beneficial effects:

[0015] 1. When the utility model is in use, the cylinder connection assembly for the robot arm adopts a split structure through the provided mounting frame, mounting holes, fastening bolts and clamping components. The mounting frame and the mounting plate are double fixed by clamping the clamping block and the clamping groove and screwing the fastening bolts and the mounting holes. When the mounting frame or the mounting plate is damaged, only the damaged parts can be replaced without replacing the entire connecting piece, thereby saving production costs.

[0016] 2. When the utility model is in use, the cylinder connecting assembly for the robot arm can move the connecting seat to a suitable installation position to cooperate with the installation of the cylinder through the oblong hole, the mounting seat, the slider and the slide groove. At the same time, the oblong hole will not hinder the mounting seat, so that changes can be made according to the actual situation of the robot arm, which is more flexible, free and practical to use.
