The utility model relates to the surface treatment device technical field of synthetic leather, specifically is the surface treatment device of waterborne polyurethane synthetic leather, including support seat, fixedly connected with loading box on support seat, rotationally connected with stirring rod on loading box, rotationally connected with coating roller on loading box, fixedly connected with rotating rod on stirring rod, slidingly connected with sliding block on rotating rod, rotationally connected with connecting rod on sliding block, fixedly connected with liquid storage bucket on support seat, fixedly connected with connecting pipe on liquid storage bucket, slidingly connected with sliding cylinder on connecting pipe, fixedly connected with piston on sliding cylinder, install second check valve on sliding cylinder, install first check valve in connecting pipe, piston slidingly connected in connecting pipe, fixedly connected with connecting shaft on sliding cylinder, rotatably connected between connecting shaft and connecting rod, solve the technical problem that material supplementing is inconvenient and coating is layered in existing roll coating equipment, thereby improve synthetic leather production efficiency and product quality, reduce enterprise production cost.

The application relates to the technical field of terminal feeding, and particularly discloses a terminal feeding device for automobile wire harness production, which comprises a feeding structure, a guiding conveying device and a clamping feeding device. The feeding structure can orderly arrange and directionally convey terminals. The guiding conveying device is arranged at the bottom top surface rear end center of the feeding structure. The guiding conveying device can limit the terminals, buffer the feeding impact, stepwise transmit and accurately limit, and guarantees the stable and orderly conveying process. The clamping feeding device is arranged at the bottom top surface right end rear corner of the feeding structure. The clamping feeding device can clamp, limit and fix the terminals in the output end of the guiding conveying device, and accurately position and feed the terminals. The application improves the high precision, high stability and strong versatility of terminal conveying, can effectively reduce the terminal damage and jamming failure, and is suitable for the flexible production and accurate operation of terminals of multiple specifications.

The application provides a full-shielded stacked radio frequency transmission line, which comprises a signal line, a first lateral shielding body, a second lateral shielding body, a first shielding line and a second shielding line; the first lateral shielding body, the first shielding line, the second lateral shielding body and the second shielding line are sequentially connected in a head-to-tail mode to form a shielding cavity, and the signal line is arranged in the shielding cavity. The full-shielded stacked radio frequency transmission line provided by the application has the advantages of high frequency shielding. In addition, the application also provides a manufacturing method of the full-shielded stacked radio frequency transmission line.

The electrostatic chuck base comprises a base body provided with a cavity with an upward opening, a vortex-shaped guide plate arranged at the bottom of the cavity, a vortex-shaped cooling groove formed between the guide plate and the cavity, and a soldering lug groove formed in the upper end face of the guide plate and extending in the length direction of the guide plate; the cover plate covers the guide plate and forms a cooling flow channel with the cooling groove, and a gap is formed between the upper end face of the guide plate located on the inner side of the soldering lug groove and the cover plate; and the soldering lug is arranged in the soldering lug groove, the thickness of the soldering lug is the same as the depth of the soldering lug groove, the soldering lug is heated and melted, and the melted soldering lug fills the gap through the capillary action. According to the scheme, the connecting strength of the cover plate on the base body is improved, and the problems that in the welding and heating process of the base, the cover plate warps to cause liquid mixing of a cooling flow channel in the base and the cover plate swells to affect the flatness of the base under the condition that the cooling flow channel is pressed for a long time are solved.
