Description

Technical Field

[0001] The utility model relates to a cross-position manipulator applied to a toy injection molding machine. Background Art

[0002] In the production process of toy plastic products, two injection molding machines are often used for linked production. That is, during the toy injection molding process, multiple injection moldings are required. Therefore, a manipulator that can transfer materials up and down across two injection molding machines is needed.

[0003] When the cross-position manipulator in the prior art picks and places the injection-molded products, infrared induction is used to avoid each other to prevent collisions. However, when the infrared induction fails, the manipulators cannot sense and avoid each other in time, resulting in collisions. Moreover, after the collision, the manipulators still run because they cannot stop suddenly, which is likely to further exacerbate the accident and there are obvious potential safety hazards. Summary of the Invention

Specifically, after the guide post 3422 aligns with the sleeve 3411 and passes through the fixed plate 341, by screwing in a nut, it can prevent the support spring 3423 from pushing the pressure relief top plate 3421 away from the fixed plate 341. At the same time, the thimble 3424 aligns with the button hole 3412 and can contact the emergency stop switch 343 after passing through the button hole 3412 when the pressure relief top plate 3421 is squeezed.

Specifically, the slide rail provided on the Y - axial moving plate 321 is assembled with the Y - axial fixed sliding block 314, and then the fixed sleeve 324 is fixed to the X - axial moving plate 311 by bolts. During actual operation, the lead screw motor 322 drives the lead screw 323, so that the Y - axial moving plate 321 performs Y - axial movement on the X - axial moving plate 311.

The output end of the Z-axis driving motor 336 with the gear passes through the sliding sleeve seat 332 and meshes with the Z-axis rack 335. Specifically, it can drive the Z-axis main body 334 to perform Z-axis movement.

[0033] The structure of the second robotic arm assembly 4 is the same as that of the first robotic arm assembly 3, and the anti-collision mechanisms installed on the second robotic arm assembly 4 and the first robotic arm assembly 3 are arranged opposite to each other. That is, after the first robotic arm assembly 3 and the second robotic arm assembly 4 collide out of control, both can be blocked by the anti-collision mechanisms and an emergency stop operation can be performed in a timely manner.
