The invention is applicable to the opening of the cable trench cover plate.

The invention provides an automatic sorting method of customized furniture plate element vertical placement transmission. The method is characterized by comprising a setting work procedure, a feedingwork procedure, a sorting work procedure and a material discharging work procedure which are sequentially executed, wherein in the setting work procedure, the corresponding relationship of each plateelement and plate element vertical placement space of the sorting device is respectively set; in the feeding work procedure, each plate element of the current batch to be sorted is subjected to information scanning in a grouped way, and the vertical and parallel feeding is performed; and in the sorting work procedure, a moving device carries the plate element to move, so that one-by-one correspondence between the plate element vertical placement space of the moving device where the plate element is positioned and the corresponding plate element vertical placement space position of the sortingdevice is realized, and the plate element is conveyed into the sorting device from the moving device, so that the goal of arranging each plate element in the set plate element vertical placement spaceof the sorting device is achieved. The sorting method provided by the invention has the advantages that the automatic plate element sorting can be realized, so that the packaging of the plate elementby workers in the subsequent work procedure can be convenient; the production efficiency is improved; the missing placement and the wrong placement of the plate element are prevented; and the occupied area is reduced.

The invention belongs to the technical field of reflector packaging, and discloses a method for fixing a coated optical fiber reflector, comprising: setting a quartz package with a through groove, and making the notch of the through groove upward; Gel is injected into the groove to form a first gel layer, and the outer surface of the first gel layer facing the notch through the groove is a support plane, so that the support plane and the notch through the groove Arranging at intervals; extending one end of the coated optical fiber into the through groove, so that the part of the coated optical fiber extending into the through groove extends along the through direction of the through groove, and is placed on the support plane Above: gel is injected into the through groove to form a second gel layer, so that the second gel layer encapsulates part of the coated optical fiber in the through groove. In the present invention, the quartz package can release the deformation of the package gel itself when it expands with heat and contracts with cold through the opening on one side of the groove.

The invention discloses a preparation method of plywood. Placement: the veneer soaked in the compound agent is fixed inside the placement frame, and the placement frame equipped with the veneer is placed in the middle of the lower splicing frame at the top of the bottom plate, and the screw rotates The upper splicing frame body moves downward and covers the top of the lower splicing frame body. The upper splicing frame body and the lower splicing frame body of the present invention are spliced ​​together to form a sealed frame, which functions as a sealed tank. The veneer soaked in the compound agent inside the frame is in a sealed environment, and the heating plate is used to heat the inside of the sealing frame, and at the same time, the air inside the sealing frame is sucked into the air pressure tank by using the pressure regulating valve and the connecting air channel, thereby improving the sealing The pressure inside the frame makes the veneer in a high-temperature and high-pressure environment inside the sealed frame, which can promote the diffusion of the soaked composite agent molecules into the veneer, improve the toughness of the surface fibers of the veneer, and effectively enhance the fracture resistance of the veneer.
