The invention belongs to the technical field of diamond preparation and discloses a method and a system for splicing and growing single-crystal diamonds. The method comprises the following steps: putting a seed crystal into a plasma CVD equipment cavity, sucking off ultimate pressure, introducing hydrogen, inputting energy, generating power discharge, and adjusting the temperature of the seed crystal; introducing a methane (or carbon-containing gases such as acetone and carbon dioxide) gas, growing the seed crystal for 1-100 hours at 800-1000 DEG C, and the like. According to the method, single-crystal diamonds are grown by using a CVD method through spicing growth, the purpose that the single-crystal diamonds is grown in a large scale is achieved, synthesis sizes directly depend on sizesof the seed crystals since conventional growth of single-crystal diamonds can be only longitudinally amplified on original seed crystals, two single-crystal diamond flakes of a same size and approximate thicknesses are fixed and spliced and grown simultaneously, then a large-size single-crystal diamond is grown, and bottle neck problems are solved.

The embodiment of the invention discloses a device for carrying cassettes, which is used for carrying the cassettes among a crane of a storage cabinet, load ports and unload ports. According to the invention, a carrying port area is arranged at the front sections of the load ports and the unload ports, a horizontal carrying mechanism and a vertical carrying mechanism are arranged at the carrying port area, and empty cassettes at the load ports are carried to the predetermined unload ports. The invention also provides a method for carrying the cassettes. According to the embodiment of the invention, the carrying amount of the crane in the storage cabinet can be reduced, so that the bottle neck that the carrying amount of the crane in the existing storage cabinet is too large can be effectively solved, and further, the productivity can be improved.

The invention provides an embedded metal bottle opening structure of an IV-type hydrogen storage bottle. The embedded metal bottle opening structure comprises a valve seat, a plastic liner, a pressing cover and a winding layer; the valve seat is provided with a valve seat bottleneck and a valve seat shoulder, and the valve seat is connected with a bottle valve through internal threads; external threads and a sealing groove are formed in the outer cylindrical surface of the valve seat bottleneck; a valve seat shoulder conical surface is arranged on the outer edge of the valve seat shoulder; the valve seat is connected with cover the pressing through the external threads, and an annular cavity is formed between the pressing cover shoulder and the valve seat shoulder; a valve seat annular groove is formed in the upper surface of the valve seat shoulder, a pressing cover annular groove is formed in the lower surface of the pressing cover shoulder, and the valve seat annular groove and the pressing cover annular groove are distributed in a staggered mode in the radial direction; the sealing groove is formed in the joint of the neck of the valve seat and the neck of the pressing cover; the upper part of the plastic liner is filled in the annular cavity in an injection molding mode and is fixedly connected with the valve seat and the pressing cover; an annular boss of the pressing cover is embedded into the outer edge of the plastic liner; and the winding layer is wound on the outer wall surfaces of the plastic liner and the pressing cover.

The invention belongs to the technical field of medicine packaging and particularly relates to a child wrong cover-opening medicine bottle for medicine packaging. The child wrong cover-opening medicine bottle for medicine packaging can prevent a child from wrongly taking a medicine, protect life safety of the child and improve safety. The child wrong cover-opening medicine bottle for medicine packaging comprises a medicine bottle body and the like. A bottle neck is installed in the middle of the top of the medicine bottle body, fixing units are installed on the front side face of the bottle neck, and a first opening unit is installed on the rear side of the bottle neck; and a bottle cover matched with the bottle neck is installed on the periphery of the bottle neck, first grooves matched with the fixing units are formed in the left side and the right side of the front side in the bottle cover correspondingly, and a through hole is formed in the rear side face of the bottle cover. According to the child wrong cover-opening medicine bottle for medicine packaging, the child is not prone to open the bottle cover through the fixing units and a rubber ring, the bottle neck is blocked through a baffle, and in this way, the medicine in the medicine body can be prevented from pouring out after the bottle cover is opened by the child.

The invention provides a chopper, wire bonding equipment and a wire bonding method. The chopper comprises a conical part and a bottleneck part, the bottleneck part is connected to the tail end of the conical part, the conical part and the bottleneck part are provided with wire holes for a metal wire to pass through, and the included angle between the end surface of the bottleneck part and the horizontal plane is not greater than 5 DEG. The chopper of the wire bonding equipment is improved, the bottleneck part of the chopper is designed to be rectangular, the inclination angle of the tail end of the bottleneck part is greatly reduced, the size of the metal ball is greatly reduced and ranges from 140 [mu]m to 160 [mu]m, the requirement of the vertical wire bonding process for the size of a metal wire can be met, and the integration level of wafer-level packaging is effectively improved.

The invention discloses a multi-sealing fork edge bag making machine and a bag making process. The multi-sealing fork edge bag making machine comprises a feeding device, an adjusting device, a material distributing device, a valve adding device, a converging station, a traction device, a heat sealing device and a material cutting device. The multi-sealing fork edge bag making process comprises the processing steps of feeding, valve adding, longitudinal sealing, cooling, upper bottle neck opening extending section heat sealing, upper bottle neck opening heat sealing, lower bottle neck opening heat sealing, lower bottle neck opening extending section heat sealing, V-shaped heat sealing, transverse sealing, cooling and cutting off. According to the multi-sealing fork edge bag processing device, full-automatic streamlined operation can be achieved, the problems that an original multi-sealing fork edge bag can only be manually processed, the production quality cannot be guaranteed, and the production efficiency is low are solved, the production efficiency is greatly improved, the processing consistency of products is good, and the production quality is high.
