5results about How to "Reduce drive costs" patented technology

This utility model relates to the field of CNC machine tool technology and discloses a convenient tool-changing drilling and milling device, including a frame, a tool magazine, a tool chuck, and a drive unit. The frame includes a worktable for supporting and positioning workpieces. The tool magazine is located above the tool chuck and has at least three mounting positions spaced apart. These mounting positions are for mounting any tool such as a drill bit, milling cutter, or tap. The tool chuck is used to hold or release the tool. The drive unit is located on one side of the worktable and includes a horizontal drive mechanism, a rotary drive mechanism, and a lifting drive mechanism. The horizontal drive mechanism is connected to the tool magazine and the tool chuck and is used to drive the tool magazine and the tool chuck to move along the length and / or width of the worktable. The rotary drive mechanism and the lifting drive mechanism are both connected to the tool chuck and are used to drive the tool chuck to rotate and move vertically, respectively. This utility model solves the problem of convenient tool changing.

The application discloses a swing type card sorting machine card turning mechanism and a card sorting machine thereof, which comprises an accepting card plate capable of turning back and forth between an accepting position and a temporary storage position, two interval arranged stand columns and two swing arms, the upper end of the swing arm is rotatably arranged in the upper end of the corresponding stand column, and the two ends of the accepting card plate are fixedly connected to the lower end of the swing arm, so that the accepting card plate fixed to the lower end of the swing arm is driven to turn over by the rotation of the upper end of the swing arm. The application designs the swing type card sorting machine card turning mechanism, so that the face-up playing cards on the accepting card plate are simultaneously driven to turn over, the card turning structure is simple, the contact with the playing cards is less during the card turning process, and the abrasion of the playing cards is greatly reduced.

This invention relates to an automatic soldering device for circuit board leads, comprising a carrier plate, a support platform, and a support frame, wherein the support platform is mounted on the side of the carrier plate. This invention relates to the technical field of circuit board processing and assembly. Beneficial effects: In use, this invention uses a soldering component to perform soldering, simultaneously feeding the solder wire. During soldering, the solder wire can be directly pulled out, and after soldering, the conveyor belt automatically moves forward. This eliminates the need for separate control of the solder wire feeding and conveying devices during soldering, thus saving on drive costs. Furthermore, after a certain period of use, no maintenance or replacement is required for the drive component and the servo motor in the conveying device, allowing for continuous use and eliminating the need for maintenance. Therefore, this achieves cost savings and increased efficiency.

The application discloses a greenhouse microclimate intelligent sensing and self-adaptive regulation device, and belongs to the technical field of agricultural greenhouses. The structure can include a plurality of groups of greenhouse frames. Linkage adjustment components are arranged between two groups of the greenhouse frames. The linkage adjustment components include two groups of positioning plates. An electric push rod is rotatably arranged on the inner side of the upper end of the positioning plate. An extension rod is arranged at the output end of the electric push rod. The linkage adjustment components and the greenhouse frames are matched. The temperature sensor components are driven to adjust the position in a linkage mode, so that the temperature in the greenhouse is detected across a range. The shading net is expanded by adjusting the spacing. The use of the driving motor is effectively reduced. The driving cost is greatly reduced. A single motor can change the position of the temperature sensor, so that the microclimate in the greenhouse is detected across a range. The device detection and driving cost are effectively reduced.

This application provides a display device and its driving method. The display device includes a display panel. The display panel includes a plurality of pixel units. Each pixel unit includes a first sub-pixel and at least one second sub-pixel. The first sub-pixel includes a first driving circuit and a first light-emitting diode. The first driving circuit includes a first pulse amplitude modulation control module, a first transistor, and a second transistor. The second sub-pixel includes a second driving circuit and a second light-emitting diode. The second driving circuit includes a second pulse amplitude modulation control module, a second pulse width modulation control module, a third transistor, and a fourth transistor. The technical solution of this application reduces the number of data signal lines, lowers the complexity of the driving circuit, improves color point stability and brightness uniformity, reduces transient current peaks, and improves the reliability of the display device.
