The invention provides a conveying device used in the manufacture of automobile wheel hubs, which belongs to the technical field of conveying devices. It solves the technical problems such as the insufficient stability of the automatic conveying of the existing automobile wheel hub. The conveying device includes a strip-shaped frame and a tray. Guide plates are provided on both sides of the top of the frame. The two guide plates are arranged in parallel and spaced apart, and the inner side of the guide plate has guide rails along the length direction of the frame. The two sides of the tray are slidingly embedded. In the guide rails of the two guide plates, one end of the frame is provided with a drive shaft, the other end of the frame is provided with a driven shaft, and a transmission part is set between the drive shaft and the driven shaft, and a drive tray is fixedly connected to the transmission part The pusher moves along the guide rail; the tray is provided with a placement plane for placing the hub and a positioning piece for fixing the hub. The conveying device designed in the present invention avoids collision or frictional damage on the surface of the hub; moreover, the hub does not shift or shake, and the position is accurate and reliable.

The invention discloses an LED light bar and a manufacturing method thereof. Aiming at the problems that the existing LED light bar has a thick thickness, high cost, positional deviation and easy falling off of shear marks, the manufacturing method of the LED light bar provided by the present invention makes The flexible circuit board of the obtained LED light strip is directly provided with marked holes or marked gaps to mark the cutting position. Compared with printing cutting marks on the surface of the light strip packaging adhesive layer, there will be no falling off, and the reliability is better; Mark holes are set between adjacent circuit cutting units on the flexible circuit board, and the setting position is more accurate and reliable, so as to avoid the cut LED light bar from not working normally; at the same time, the LED light bar can directly set the first LED chip Encapsulation on a flexible circuit board can omit the production process of LED brackets and LED lamp beads compared to the current LED light strips. The production efficiency is higher and the cost is lower. The obtained LED light strips are COB light strips, which are thinner and can be Better meet the needs of various application scenarios.

A contents border detection apparatus and monitoring method. The apparatus comprises a digital watermark detector for detecting a digital watermark embedded in contents for which a time element is provided; and a border detector for detecting border locations for the contents corresponding to the state of the digital watermark detected by the digital watermark detector. The border detector includes a first border specification device for specifying the border locations for the contents based on information, written in the digital watermark, that is detected by the digital watermark detector and includes a second border specification device for specifying the border locations for the contents based on bit patterns embedded as the digital watermark. The border locations for the contents are detected by using the process result obtained both by the first and the second border specification devices.

A surgical device for ophthalmic surgery, comprising pressing material, light guide fiber, traction strip and arc-shaped support, the pressing material and traction strip are respectively arranged on the inner side and outer side of one end of the arc-shaped support, and the middle part of the pressing material is A hollow channel is provided, and a through hole is provided corresponding to the hollow channel on the arc-shaped support. A hollow area is provided on the traction strip, and the connection between the traction strip and the arc-shaped support can be rotated freely. The through hole is embedded in the hollow channel. When the surgical device is in use, the pressing material can be aligned with the central area of ​​the macula through the light guide fiber, and the pressing height can be adjusted through the traction strip, and the arc-shaped bracket can be adjusted through the relative rotation between the traction strip and the pressing end. The suture position can make the implantation position of the pressing material accurate and reliable, the implant is stable for a long time, the operation is simple, and the side effects are few. It is suitable for the treatment of progressive deepening of high myopia and complications related to posterior staphyloma.

The invention discloses a quick capsule replacing center mechanism for a tire vulcanizer. A quick chuck replacing mechanism consisting of a steel ball retaining ring, a locking ring, a steel ball, a connecting rod and a locking cylinder can quickly replace a capsule and a sealing ring, time is saved, and the work efficiency of the vulcanizer is improved; an upper ring lifting water cylinder is separated from a ring seat and has an independent structure, so that processing and installation difficulty is reduced, internal pressure superheated water can be prevented from leaking and entering the water cylinder, and the service life of the sealing ring of the water cylinder is prolonged; and the water cylinder has a single-piston structure and is provided with a built-in displacement sensor, so that the straightening height and forming height of the capsule can be accurately controlled.
