The application relates to the technical field of dental implants, in particular to a trans-zygomatic implant and a processing technology thereof, and the processing technology comprises variable-distance multi-stage sand blasting and acid etching surface treatment on an anchoring part with threads of the trans-zygomatic implant and electrochemical polishing surface treatment on an extension part without threads. The trans-zygomatic implant is treated by variable-distance multi-stage sand blasting combined with acid etching, so that a uniform micron-level rough base and a multi-stage micropore structure can be formed on the titanium surface, osteoblast adhesion and differentiation are facilitated, the early bone combination speed is accelerated, the combination strength is improved, the early implant loosening risk is reduced, the extension part of the trans-zygomatic implant is treated by electrochemical polishing, a smooth surface can be obtained, plaque adhesion and bacterial colonization are greatly reduced, the implant peri-implantitis risk is reduced, and soft tissue adhesion is promoted; the dual optimization of bone anchoring and tissue adhesion is realized, and the long-term function and health of the trans-zygomatic implant under complex stress are guaranteed.

The utility model relates to the technical field of wastewater sedimentation, in particular to a wastewater sedimentation tank with a stirring structure, which comprises a sedimentation tank, drain outlets are arranged at the lower ends of the surfaces of the left and right sides of the sedimentation tank, observation mechanisms are rotatably connected to the top ends of the surfaces of the front and rear sides of the sedimentation tank, and a stirring mechanism is rotatably connected to one side of the upper surface of the sedimentation tank. Connecting blocks are welded to the left and right sides of the upper ends of the front and rear surfaces of the sedimentation tank, connecting holes are formed in one sides of the connecting blocks, and connecting grooves are formed in the left and right ends of the front and rear surfaces of the upper surface of the sedimentation tank. After a flocculating agent is added into the sedimentation tank, a water body can be stirred through the stirring mechanism, the combining speed of the water body and the flocculating agent is increased, and when the stirring mechanism needs to be cleaned, the lifting handle can be held by hand to control the stirring mechanism to rotate upwards to be opened, so that the stirring mechanism can be cleaned.

The utility model provides a packaging plate and a photovoltaic assembly, relates to the field of photovoltaic technology, and aims to solve the technical problem that the service life of the photovoltaic assembly is shortened due to the fact that the photovoltaic assembly is difficult to effectively prevent water vapor from entering the assembly from the peripheral edge. The packaging plate is provided with a surface facing the photovoltaic cell, and the surface is provided with a first area and a second area annularly arranged outside the first area; the first area is used for being connected with a photovoltaic cell, and the second area is used for being connected with a first sealing structure for preventing water vapor from entering the photovoltaic cell; the roughness of at least part of the first area is larger than that of the second area. The packaging plate is used for packaging the photovoltaic cell, and the smooth plane is arranged in the corresponding area of the packaging plate and the sealing structure, so that the bonding effect of the packaging plate and the sealing structure is improved, and water vapor is prevented from intruding into the photovoltaic cell.

The invention belongs to the technical field of welding equipment, and particularly relates to an automatic welding device for a sewing machine rack, the automatic welding device comprises a welding table, first electric sliding rails are fixedly mounted on the two sides of the welding table, the two first electric sliding rails are jointly connected with a supporting frame in a sliding mode, and a second electric sliding rail is fixedly arranged on the supporting frame; and a sliding seat is slidably connected to the second electric sliding rail, an electric cylinder is fixedly arranged on the sliding seat, a welding head is fixedly connected to the output end of the electric cylinder, and a PLC is fixedly arranged on one side of the welding table. According to the automatic welding device, the sewing machine rack to be welded can be automatically welded, the complexity of manual welding is avoided, smoke dust generated in the welding process can be washed with water, meanwhile, clean water for washing can be monitored, a worker can be reminded, the worker can replace the washing liquid in time, and the welding efficiency is improved. And the reduction of the smoke treatment effect caused by poor water quality is avoided.
