6results about How to "Reduce coverage area" patented technology

The utility model relates to quenching device technical field, and disclose a kind of quenching device of metal heat treatment, including equipment main body, fixed in the fixed telescopic link of equipment main body upper surface one side and the bracket fixed in telescopic link top, the inside fixed drive device of one side of the bracket, the upper surface of equipment main body another side is fixed with quenching tank.This equipment is rotated by the high friction of sharp cone rubber wheel and quenching tank inner wall, and then rotates by gear engagement to drive metal bar and steel wire brush roller rotation, forms the bidirectional rotation cooperation of metal bar and brush roller, realizes the quick removal of the surface scale of metal bar, this process can effectively reduce the scale coverage area, avoid scale residue to hinder quenching liquid contact, ensure that quenching heat transfer is uniform, improve quenching quality.

This utility model relates to the field of disposable hygiene products, specifically to a breathable menstrual panty that solves the problem of insufficient breathability at the waistband of existing menstrual panty structures. The panty includes a main body comprising a liquid-permeable surface layer, an absorbent core, and a liquid-impermeable bottom layer stacked from top to bottom. The main body has a longitudinal direction (length) and a transverse direction (width). Longitudinally, it is divided into a front waistband area near the front of the body, a back waistband area near the back of the body, and a crotch area between the two. An elastic waistband is sandwiched between the liquid-permeable surface layer and the liquid-impermeable bottom layer in the front and / or back waistband areas. A non-elastic perforated section is provided between the front and / or back waistband areas and the crotch area. Strip-shaped Velcro fasteners for adding fixing points are arranged on the liquid-impermeable bottom layer in the perforated section of the front and / or back waistband areas. This utility model is applied in the production of menstrual panties.

The utility model relates to a COB light-emitting device and a light-emitting device. The COB light-emitting device comprises a light-emitting assembly, a plurality of first lenses and a plurality of second lenses. The light-emitting assembly comprises a plurality of light-emitting chips and is provided with a plurality of light-emitting areas, and each light-emitting area is formed by the light-emitting face of the corresponding light-emitting chip. The plurality of first lenses are in one-to-one correspondence with the plurality of light-emitting areas, each first lens is arranged on the light-emitting chip of the corresponding light-emitting area, the minimum included angle between the section line of the side surface of each first lens on the optical axis section and the extension line of the section line of the bottom surface of each first lens is theta, and theta is greater than 45 degrees and greater than 90 degrees. The second lens is arranged on the light-emitting assembly and comprises a plurality of lens parts which are connected with one another, the plurality of lens parts are in one-to-one correspondence with the plurality of first lenses, and each lens part is arranged above the corresponding first lens at intervals. According to the COB light-emitting device, light emitted by the light-emitting chip is collected through the arrangement of the first lens, the size of the second lens is obviously reduced, the size of the device is obviously reduced, and miniaturization of the COB light-emitting device is facilitated.

An adjustable silicon wafer support platform for large-size silicon wafer edge polishing includes a support table, a center support rod is vertically fixed on the support table, a center support plate is fixedly connected to the top of the center support rod, a moving ring is slidably sleeved on the middle part of the center support rod, a plurality of side support rods are also slidably arranged on the support table, the side support rods are obliquely arranged relative to the support table, and the plurality of side support rods are uniformly distributed around the circumferential direction of the center support rod, the top of the side support rod is fixedly connected with an edge support plate, and the center support plate and all the edge support plates jointly form a support platform for supporting the silicon wafer, and the moving ring can push the side support rod to slide during up-down movement to change the distance between the edge support plate and the center support plate. The actual size of the silicon wafer for edge polishing can be flexibly adjusted according to the need, so that the silicon wafer can be uniformly supported, and the silicon wafer can be prevented from falling due to unstable support when the edge is stressed or being damaged due to uneven stress on the edge.

The invention discloses a pole roll three-dimensional caching system and a transferring method in the technical field of lithium battery production, the system comprises a partition wall arranged between a roll cutting area and a roll dividing area, and a rectangular winding corridor is arranged in the partition wall; a temporary storage channel is arranged in the rectangular corridor, a stacking machine is arranged in the temporary storage channel, and three-dimensional pole roll temporary storage vertical warehouses are arranged on the two sides of the temporary storage channel. Conveying lines used for pole roll feeding and discharging are arranged at the two ends of the temporary storage channel, and double-door interlocking devices are arranged at the positions, penetrating through the rectangular winding corridor, of the two ends of the conveying lines. Compared with a traditional decentralized and fixed plane-laid pole roll caching frame, the three-dimensional caching system and method for the pole rolls fully utilize the three-dimensional space and can greatly save the plane space, and compared with a decentralized flat-laid pole roll caching frame mode, the system cancels a lifting door and is integrally located in a relatively closed space, so that the space is saved, and the space is saved. The device is suitable for frequent alternate operation, environment management and control of the two areas are not affected, and the pole rolls are also greatly protected from being polluted.
