The invention discloses an electromechanical equipment mounting stand. The electromechanical equipment mounting stand comprises air spraying devices, a fan, a top cover, a stand bin, a side wall ejector rod, an equipment mounting base, a bin door, a stand bin support rod and a lifting moving device; the top cover is arranged at the top of the stand bin; the fan is arranged at the top of the standbin; two air spraying devices are arranged at the top end in the stand bin, and are connected with the fan; the side wall ejector rod is arranged on the side wall of the stand bin; the bin door is arranged on the stand bin; the equipment mounting base is arranged at the bottom end in the stand bin; the stand bin support rod is arranged on the bottom edge of the stand bin; and the lifting moving device is arranged in the bottom center of the stand bin. The electromechanical equipment mounting stand can achieve the functions of cooling and dedusting on electromechanical equipment through the fan, can stably fix the electromechanical equipment in the stand bin, can provide excellent mounting environment to the electromechanical equipment, and can realize easy movement of the electromechanicalequipment through the lifting moving device.

The invention provides a bearing buffer unit for a motor, comprising motor spindles, wherein the motor spindles pass through the centers of a stator core and a rotor core, and are respectively fixed in the upper end cap and the lower end cap of a motor by an upper bearing device and a lower bearing device; the upper bearing device comprises upper end cap bearings which are fixed at the spindles; the upper end cap bearings are arranged in a concave platform of the upper end cap of the motor; the upper end cap bearings in the concave platform are respectively provided with an upper bearing elastic element in a radial direction; each upper bearing elastic element is provided with an upper sealing cover plate in an axial direction; the lower bearing device comprises lower end cap bearings which are fixed at the spindles; the lower end cap bearings are arranged in an inner concave platform of the lower end cap of the motor; each lower end cap bearing in the inner concave platform is provided with a lower bearing elastic element in a radial direction; and lower sealing cover plates are arranged in an outer concave platform of the lower end cap of the motor. The above technical scheme is used to overcome the defects that bearings for an existing motor are easily extruded mutually and damaged at the joints of the spindles and the end caps due to high-speed running, heat emission, parking, cooling, deformation and the like, the tail ends of the spindles of the motor are exposed and the like. The bearing buffer unit is used for controlling motors in different freezing operating rooms.

The invention discloses a novel automatic edge covering device for a daylighting panel production line. The device comprises a working platform, reshaping mechanisms, striking-off mechanisms and an extrusion roller, wherein support legs are arranged on the lower part of the working platform; a daylighting panel is arranged on the upper part of the working platform; edge covering belts are arranged on the two sides of the daylighting panel; the reshaping mechanisms are arranged on the upper parts of the edge covering belts; each reshaping mechanism comprises a disc, a pressure wheel, a bracket and a connecting rod; sliding blocks are arranged on the upper parts of the brackets; the connecting rods are arranged on the upper parts of the sliding blocks; the angles of the connecting rods relative to the daylighting panel can be freely adjusted; each disc is arranged at one end of the corresponding connecting rod; the pressure wheels are arranged on the upper parts of the discs, and are movably connected to the brackets; the edge covering belts are arranged between the discs and the pressure wheels; the striking-off mechanisms are arranged on the rear sides of the reshaping mechanisms; each striking-off mechanism comprises a bracket, a connecting rod and a scraper; the connecting rods are arranged on the brackets; each scraper is arranged at one end of the corresponding connecting rod. According to the device, the edges of the daylighting panel are automatically covered in the daylighting panel production process, and the daylighting panel is strong in strength; the two sides of the daylighting panel are not required to be cut, so that cutting waste is avoided, and the device is safe and environment-friendly.

Embodiments of the present invention provide an antenna tuning method and a terminal. The method includes: when the first antenna is in the working state and the second antenna is in the standby state, acquiring the first working frequency band of the first antenna; according to the preset working frequency band of the first antenna and the corresponding relationship between the at least two second radio frequency channels, determine the target radio frequency channel corresponding to the first working frequency band among the at least two second radio frequency channels; control the second power amplifying unit to turn on The second antenna communicates with the target second radio frequency. In the embodiment of the present invention, the radiation power of the antenna in the working state is adjusted by using other antennas and the load on the radio frequency path that can be connected with other antennas, so that the antenna can work with better working efficiency, which can save The use of the antenna tuner is eliminated, and the production cost of the terminal is reduced.
