The present invention relates to a welding wire device for a solar cell without a main grid, comprising: a machine base, a welding mesh wiring board is provided on the machine base, longitudinal wire grooves and transverse wire grooves arranged in a vertical and horizontal cross arrangement are provided on the welding mesh wiring board, and the intersection of the longitudinal wire grooves and the transverse wire grooves is a cross welding point; a longitudinal wiring mechanism, the longitudinal wiring mechanism is used to arrange the welding wire in the longitudinal wire groove; a transverse wiring mechanism, the transverse wiring mechanism is used to arrange the welding wire in the transverse wire groove; a multi-head welding device, the multi-head welding device is located above the welding mesh wiring board, and the multi-head welding device is provided with a welding wire cross welding head matching the cross welding point, which is used to weld the vertical and horizontal cross welding wires into a welding mesh. The present invention adopts a pre-compiled welding mesh, and then the entire welding mesh is laid out before welding, which not only improves the efficiency of welding the battery cell, but also reduces the exposure of the battery cell, better guarantees the welding quality of the battery cell, and improves the conversion efficiency of the battery cell.

The application relates to the technical field of fabric support, in particular to a wrinkle-preventing silk fabric suspension type shaping support structure, which comprises a suspension support, a top plate, a cloth winding shaft, an auxiliary beating assembly and a wrinkle-removing positioning assembly, the top plate is fixedly connected at the top of the suspension support, and the wrinkle-removing positioning assembly is installed at the side of the suspension support close to the auxiliary beating assembly. The wrinkle-preventing silk fabric suspension type shaping support structure of the application simulates the natural unfolding effect of manual beating through low-frequency vibration of the auxiliary beating assembly, and avoids the damage of high temperature or chemical treatment to silk fibers. The cloth winding shaft symmetrically winds large-size silk fabrics, so that the fabrics are uniformly stressed in a suspension state, and folding marks are completely eliminated, and meanwhile, the transverse occupied space is saved; the fabric is gently pressed against the fabric edge by rotating the handle to drive the threaded rod, so that the vertical direction of the fabric is maintained, and oblique distortion wrinkles are avoided; the limiting block ensures that the fabric does not displace during beating, and the wrinkle-removing efficiency is improved.

The present invention relates to a busbar-free solar cell welding device, comprising: a welding mesh welding device, used to weld welding wire into a welding mesh; a cell welding machine, used to weld the welding mesh and busbar-free cells into solar cell plates; a cell feeding device, used to transport the cells to the cell welding machine; a welding mesh feeding device, used to transport the welding mesh formed by the welding mesh welding device to the busbar-free cells on the cell welding machine. The present invention adopts a pre-made welding mesh, and then the entire welding mesh is laid before welding, which not only improves the efficiency of welding cells, but also reduces the exposure of cells, better ensures the welding quality of cells, and improves the conversion efficiency of cells.

The invention belongs to the technical field of cosmetics, and provides a traditional Chinese medicine composition for blackening and developing hair as well as a preparation method and application thereof, and the traditional Chinese medicine composition comprises the following raw materials in parts by weight: 3-6 parts of polygonum multiflorum, 3-6 parts of angelica sinensis, 2-5 parts of oroxylum indicum and 3-5 parts of lycium ruthenicum. The composition disclosed by the invention has the effects of alleviating the growth environment state of hair follicles and promoting melanin cells to generate melanin, and is easier to absorb by scalp by adopting a nanotechnology. The preparation method of the traditional Chinese medicine composition is simple and convenient, and large-scale production and application are facilitated.

The present application discloses a regular assembly, a bearing module, a battery string bearing mechanism and a string welding machine, and belongs to the technical field of photovoltaic battery string production equipment. The regular assembly of the present application includes a support, n guide slots and a reset member, the n guide slots and the reset member are arranged in the support, the reset member is configured to drive the corresponding n guide slots to be in a first position, the upper surface of the support is configured to carry a plurality of welding strips extending along a first direction, and each guide slot is configured to allow a welding strip carried along the upper surface of the support to fall into; after the battery cell is pressed on the n guide slots, the guide slots are pressed down to the second position by the battery cell, so that the welding strip defined in the guide slots fits the lower surface of the battery cell; after the battery cell and the welding strip are separated from the regular assembly, the reset member is also configured to drive the n guide slots from the second position back to the first position. The present application helps to avoid the mutual influence between the guide slots and reduce the accuracy of the regular position of the welding strip.

The invention relates to a sunscreen synergistic composition and application thereof.The sunscreen synergistic composition is composed of an emollient, a dispersing agent and an emulsifying agent, the emollient, the dispersing agent and the emulsifying agent are all selected from specific components, all the components in the sunscreen synergistic composition cooperate with one another, the sunscreen synergistic composition is applied to a sunscreen cosmetic composition, and the sunscreen cosmetic composition has the good sunscreen effect. The sunscreen cosmetic composition has high SPF and excellent skin feeling, in addition, the sunscreen cosmetic composition provided by the invention also has excellent dosage form stability, and when the sunscreen cosmetic composition is a shake-shake dosage form sunscreen product, the shake-shake dosage form sunscreen product can be kept in a uniform state for a long time after being shaken up.
