8results about How to "Smooth peeling" patented technology

This invention relates to a method for electron beam negative photoresist lift-off, comprising: providing a substrate; forming a sacrificial photoresist layer on the substrate; forming an etch-resistant electron beam negative photoresist layer on the sacrificial photoresist layer; subjecting the electron beam negative photoresist layer to electron beam exposure to form a target pattern; developing the exposed electron beam negative photoresist layer; dry etching the sacrificial photoresist layer to form an undercut structure; depositing a target coating on the substrate; and removing the sacrificial photoresist layer and the target coating and electron beam negative photoresist layer thereon to complete the lift-off. The beneficial effects of this invention are: it uses electron beam lithography to develop a smaller electron beam negative photoresist layer, then places it in plasma etching, and obtains the undercut structure by dry etching the sacrificial photoresist layer. This reduces the area requiring photolithography and allows the negative photoresist to form an ideal undercut structure during electron beam exposure, ensuring smooth lift-off of the negative photoresist during the lift-off process.

The invention relates to the field of conveying and stripping equipment, and discloses screen sheet stripping equipment which comprises a rack and a conveying belt system arranged on the rack, the conveying belt system comprises a conveying belt used for conveying a workpiece, an adhesive tape is pasted on the workpiece, and a stripping assembly corresponding to the adhesive tape is arranged on the front side of the rack. A control assembly used for driving the stripping assembly is arranged on the machine frame, and a bearing plate which corresponds to the position of the transmission belt and is movably attached to the control assembly is arranged in the machine frame. Through cooperation of the transmission belt, the control assembly, the stripping assembly, the bearing plate and the like, the stripping assembly can be driven to move front and back and move up and down, the stripping assembly is in an ascending state when moving backwards to be close to an adhesive tape, and the stripping assembly can automatically descend to be bonded with the adhesive tape when moving backwards to be in place; the sheet can then be quickly stripped from the substrate by the adhesive tape, while the substrate is still located on the conveyor belt to be subsequently removed.

The utility model discloses a portable sealing label which comprises a label body, the label body is composed of label paper, an anti-fake layer and a bonding layer, a composite protective layer is arranged at the upper end of the anti-fake layer, a composite release layer is arranged at the lower end of the bonding layer, backing paper is arranged at the lower end of the composite release layer, and the anti-fake layer and the bonding layer are bonded together. A cutting line is arranged on one side of the interior of the label body and penetrates through the label body, the anti-fake layer is arranged at the upper end of the label paper, the bonding layer is arranged at the lower end of the label paper, release paper is arranged at the upper end of the composite protection layer, and the release paper is arranged outside the composite protection layer in a bonding mode. According to the structure, the problems that the label is not convenient to uncover and the protection performance of the label is not good enough are solved.

This utility model provides a waste film peeling device for urine bags, relating to the technical field of urine bag production equipment. A cutting structure is used to cut the urine bag film roll into multiple individual urine bags. A material transfer structure is connected to a conveying structure, which transfers the cut urine bag individual bags to a support plate of the waste film peeling structure. The support plate matches the outer edge of the finished urine bag. The waste film peeling structure includes a peeling mechanism and a cutting assembly. The peeling mechanism includes a lifting assembly and a clamping assembly. The clamping assembly clamps the four corners of the waste film on the support plate, peeling the waste film from the finished urine bag. The cutting assembly is connected to the support plate and cuts the peeled waste film. This utility model alleviates the technical problem in the prior art where, after heat-melting and cutting the urine bag sheet, the waste film cannot be guaranteed to detach smoothly from the urine bag, leading to inconvenience in subsequent processing and even a decrease in product yield.

This invention belongs to the technical field of agricultural product processing equipment and discloses a dry-type potato peeling machine and peeling method. It aims to solve the problems of high loss, uneven peeling, easy wastewater generation, and easy damage to potato flesh in traditional potato peeling technology. The peeling machine uses an aluminum alloy frame as the base and is equipped with a roller-type peeling mechanism with an eccentric support frame. It is equipped with a food-grade flexible foam peeling pad, a roller group unit rotating in opposite directions, and a spiral conveying groove with opposite rotation direction. It is supplemented by a drive component, a protective cover, and a peeling material collection structure. The peeling method includes four steps: raw material pretreatment, feeding and conveying, dry flexible peeling, and directional uniform speed discharge. Through hot scalding to soften the skin, eccentric rollers tumbling the material 360°, and flexible surface contact peeling of the skin, it achieves dry and wastewater-free operation and has the advantages of uniform peeling, low potato flesh loss, stable operation, and compliance with food-grade safety standards.
