The invention discloses a safe welt cleaning path planning method and a storage medium. The method comprises the following steps: S1, obtaining an initial optimized path result through a path planning algorithm; s2, carrying out collision detection on the initial optimized path, judging whether collision exists or not, if not, determining that the path is effective and returning to the step S3, and otherwise, carrying out the step S3; s3, through a collision detection method, obtaining a collision depth dcollision; s4, boundary adjustment is carried out on the basis of the collision depth dCollision; s5, performing path optimization based on the adjusted boundary; and S6, judging whether the optimized path is collided or not, if not, determining that the path is effective and returning to the step S1, and otherwise, returning to the step S1. By means of the method, the automatic driving vehicle can smoothly generate the welt sweeping path, meanwhile, it is guaranteed that collision cannot occur in any topological map, and the method is suitable for path planning algorithms under different coordinate systems.

The invention relates to a polishing device. The polishing device comprises a polishing table, and a polishing pad is arranged on the polishing table; the polishing assembly comprises a polishing head and a polishing driving part, the polishing head is used for adsorbing and fixing the wafer, and the polishing driving part is in driving connection with the polishing head to drive the polishing head to drive the wafer to move along the surface of the polishing pad; the trimmer comprises a trimming head and a trimming driving part, and the trimming driving part is in driving connection with the trimming head so as to drive the trimming head to move along the surface of the polishing pad; wherein in the process that the polishing head and the finishing head move along the surface of the polishing pad, the distance between the center position of the polishing head and the center position of the finishing head is larger than the sum of the radius of the polishing head and the radius of the finishing head.

This invention discloses a prefabricated steel-concrete composite beam floor structure, including frame columns, steel main beams, and steel secondary beams. Floor slabs are laid on the steel main beams and secondary beams. Connecting plates are vertically installed on the web of the steel main beams. One end of the floor slab is wrapped with angle steel. The floor slabs do not contact the frame columns. In this invention, the first floor slab is connected to the steel main beam by a first bolt, achieving a combined effect between the steel main beam and the first floor slab, improving the bending resistance and stiffness of the steel main beam. The second and third floor slabs are connected to the steel secondary beams by spot welding, ensuring that the floor slabs will not collapse under seismic loads. The third floor slab has no rigid connection to the steel main beams, allowing relative sliding between them after an earthquake, thus preventing damage to the slab. Furthermore, a gap is left between the third floor slab and the frame columns to ensure that the deformation of the frame columns under seismic loads does not collide with the floor slab, maintaining the integrity of the floor slab.

The utility model relates to an air conditioner front shell mold which comprises an upper mold plate. A die cavity is formed between the upper die plate and the lower die plate; the demolding sliding block assembly comprises an inclined guide column fixedly connected with the upper mold plate, a sliding block unit slidably connected with the lower mold plate, and a third sliding block movably connected with the sliding block unit; when the upper mold plate and the lower mold plate are demolded, the sliding block unit is driven by the inclined guide column to move in the direction away from the mold cavity, so that the third sliding block is pushed to slide in the inclined downward direction and is separated from a barb on the lower surface of the air conditioner front shell. Compared with the prior art, the injection mold does not collide with the pressing mold during demolding, so that the cost is saved, and offset and flash are not easy to generate during injection molding.

The utility model discloses a shaft groove anti-collision worm variable pitch module which comprises a worm and a sliding table, the worm is provided with a spiral track, the sliding table can move along the spiral track, the spiral track comprises a track head and a track tail, and the track tail is provided with a second anti-collision piece along the spiral track (132); the worm rotates clockwise to drive the sliding table to move towards the tail of the track along the spiral track, the sliding table abuts against the second anti-collision piece, and the worm stops rotating. The worm variable-pitch module has the advantages of being simple in structure and stable in operation, the service life of the worm variable-pitch module can be effectively prolonged, and the maintenance cost of the worm variable-pitch module is reduced.

The invention relates to the field of large plate suit cutting, in particular to a large plate suit cutting push plate guide anti-collision device. Comprising a machine tool capable of driving a plate to move and cut, and further comprises two butt-clamping mechanisms symmetrically arranged on the two sides of the machine tool, each butt-clamping mechanism comprises a movable clamping plate, and the movable clamping plates are arranged at the upper end of the machine tool in a sliding mode; the guide mechanism is connected with the movable clamping plate and comprises a plurality of positioning boxes, a plurality of extrusion bent plates and a plurality of conical guide wheels, the positioning boxes are slidably arranged in the long edge direction of the movable clamping plate at equal intervals, and the extrusion bent plates are slidably connected with the sides, close to the center line of the machine tool, of the positioning boxes correspondingly; the multiple conical guide wheels are connected with the ends, away from the multiple positioning boxes, of the multiple extrusion bent plates correspondingly, the outer portion of each conical guide wheel is fixedly sleeved with a rubber sleeve, and a vortex-shaped spiral groove is formed in each rubber sleeve; the locking mechanisms are connected with the positioning boxes respectively and comprise reset tension springs capable of driving every two adjacent positioning boxes to be close to each other.
