[0002] A robotic arm is a complex system with high precision, multiple inputs and multiple outputs, high nonlinearity, and strong coupling. It can mimic certain movements and functions of the human hand and arm. In the process of producing plastic parts in injection molding machines, robotic arms are often used to remove plastic parts.
[0003] Existing robotic arms for automatic part removal in toy manufacturing injection molding machines typically use grippers on the robotic arm to directly pick up plastic parts. However, since different toy plastic parts have different surface shapes, existing devices cannot adapt to different shapes of toy injection molded parts when picking them up using only the gripper structure, which affects the stability of the gripping process.

[0030] Please see Figures 1-4 This utility model provides an embodiment of an automatic part-retrieving robotic arm for injection molding machines used in toy production:
[0031] An automatic part-removing robotic arm for injection molding machines in toy production, comprising:
[0032] Track 1, with a robotic arm 2 mounted on its surface, and a gripper mechanism 3 and a suction cup mechanism 4 mounted on its surface;
[0033] The gripper mechanism 3 includes a fixed frame 301, a cylinder 302, a double-direction rack 303, a slide groove 304, a thick gear 305, a connecting rod 306, a gripper 307, a rotating shaft 308, a slide rod 309, and a one-way rack 3010.
[0034] The fixed frame 301 is fixedly connected to the surface of the robotic arm 2. The cylinder 302 is fixedly installed on the outside of the fixed frame 301. The bidirectional rack 303 is fixedly assembled to the output end of the cylinder 302. The slide groove 304 is opened on the surface of the fixed frame 301. The rotating shaft 308 is rotatably connected to the side of the fixed frame 301 away from the slide groove 304. The thick gear 305 is fixedly assembled to the end of the rotating shaft 308. The slide rod 309 is slidably connected to the inside of the slide groove 304. The one-way rack 3010 is fixedly assembled to the end of the slide rod 309. The connecting rod 306 is fixedly connected to one side of the one-way rack 3010. The gripper 307 is fixedly connected to the end of the connecting rod 306.
[0035] The slide groove 304 is inclined, and the outer wall of the slide rod 309 matches the inner wall of the slide groove 304. The above structural design makes it possible for;
[0036] The bidirectional rack 303 meshes with the tooth grooves of the two thick gears 305, and the bidirectional rack 303 in the moving state is used to drive the two thick gears 305 to rotate synchronously. The above structural design makes the bidirectional rack 303 mesh with the tooth grooves of the two thick gears 305, so that the bidirectional rack 303 in the descending state drives the two thick gears 305 to rotate synchronously.
[0037] The thick gear 305 meshes with the tooth groove of the one-way rack 3010, and the meshing thick gear 305 and one-way rack 3010 are used to drive the connecting rod 306 to move. The above structural design makes the tooth groove of the thick gear 305 mesh with the tooth groove of the one-way rack 3010, so that the two thick gears 305 in the rotating state drive the two one-way racks 3010 to move respectively.
[0038] In one preferred embodiment, the two connecting rods 306 in the moving state respectively drive the two grippers 307 to move synchronously. The above structural design enables the two unidirectional racks 3010 in the moving state to drive the two connecting rods 306 to move synchronously, and the two connecting rods 306 in the moving state to drive the two grippers 307 to move synchronously.
[0039] In one preferred embodiment, two jaws 307 in a close moving state are used to grip the plastic part to be gripped. The above structural design causes the two connecting rods 306 in the moving state to drive the two jaws 307 to move synchronously, so the two jaws 307 in a close moving state are used to grip the plastic part to be gripped.
[0040] In one preferred embodiment, the suction cup mechanism 4 includes a bracket 401, an air pump 402, an air supply pipe 403, and a suction cup 404;
[0041] The bracket 401 is fixedly connected to one side of the bidirectional rack 303, the air pump 402 is fixedly installed on one side of the bracket 401, the air supply pipe 403 is fixedly connected to the docking end of the air pump 402, and the suction cup 404 is set on the other side of the bracket 401. The above structural design allows the air pump 402 to be powered on and run, so that the running air pump 402 provides suction to the inside of the suction cup 404 through the air supply pipe 403, and the suction cup 404 is driven to run. The bidirectional rack 303 in the descending state drives the suction cup 404 to descend and move through the bracket 401. The descending suction cup 404 contacts the surface of the plastic part to be clamped, and the running suction cup 404 adsorbs the plastic part to be clamped.
[0042] In one preferred embodiment, the output end of the air supply pipe 403 is connected to the input end of the suction cup 404, and the energized air pump 402 is used to provide suction to the suction cup 404 through the air supply pipe 403. The above structural design allows the air pump 402 to be powered on and run, so that the running air pump 402 provides suction to the inside of the suction cup 404 through the air supply pipe 403, thereby driving the suction cup 404 to run.
[0043] In one preferred embodiment, the suction cup 404 in the running state is used to adsorb the plastic part to be clamped. The above structural design makes the suction cup 404 in the descending state contact the surface of the plastic part to be clamped, so the suction cup 404 in the running state adsorbs the plastic part to be clamped.
[0044] The working principle of this utility model is as follows: First, the air pump 402 is powered on and put into operation. The air pump 402 in operation provides suction to the inside of the suction cup 404 through the air supply pipe 403, so the suction cup 404 is driven to run. Then, the cylinder 302 is powered on and put into operation. The output end of the cylinder 302 in operation drives the bidirectional rack 303 to move downward. The bidirectional rack 303 in the downward state drives the suction cup 404 to move downward through the bracket 401. The suction cup 404 in the downward state contacts the surface of the plastic part to be clamped, so the suction cup 404 in operation adsorbs the plastic part to be clamped.
[0045] Simultaneously, because the bidirectional rack 303 meshes with the tooth grooves of the two thick gears 305, the descending bidirectional rack 303 drives the two thick gears 305 to rotate synchronously. Since the thick gears 305 mesh with the tooth grooves of the one-way rack 3010, the rotating thick gears 305 respectively drive the two one-way racks 3010 to move. The moving one-way racks 3010 respectively drive the two slide rods 309 to move along the trajectories of the two slide grooves 304, and the slide grooves 304 and slide rods... When the two unidirectional racks 309 move smoothly in conjunction with the auxiliary unidirectional racks 3010, the two unidirectional racks 3010 in the moving state drive the two connecting rods 306 to move synchronously. The two connecting rods 306 in the moving state drive the two grippers 307 to move synchronously. The two grippers 307 in the moving state that are close to each other grip the plastic part to be gripped. Thus, by the two grippers 307 moving synchronously with the suction cup 404, the plastic part to be gripped is gripped, which effectively improves the stability of gripping the plastic part to be gripped.
[0046] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
