Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent instrument assembly workbench, and more specifically, particularly relates to an intelligent instrument assembly workbench. Background Art

[0002] Smart meters are intelligent meters that use microcomputers (single-chip microcomputers) as their main body and organically combine computer technology and detection technology. Smart meters contain a variety of high-precision electronic components such as circuit boards. When factories assemble smart meters, they need to assemble workbenches to complete the assembly of smart meters. Existing assembly workbenches are usually composed of negative pressure devices, telescopic table lamps, frames, countertops and accessories. The frame is the skeleton of the workbench, which is responsible for bearing the weight of the workbench and supporting the countertop. The countertop is the main working part of the workbench. Accessories are various components used to enhance the functions of the workbench, such as drawers, shelves, light sources, etc. When assembling smart meters, the telescopic table lamp is responsible for providing lighting when the brightness is not enough. In order to achieve the best lighting effect and the maximum lighting range, the telescopic table lamp is generally installed above the countertop. The negative pressure device can prevent dust from entering the inside of the smart meter.

[0003] The existing application number is: CN201920144577.8. The utility model discloses an instrument assembly workbench, including a workbench main body, a motor placement box is arranged on one side of the workbench main body, a motor is arranged inside the motor placement box, and the output end of the motor is connected to a connecting block through a threaded rod. The instrument assembly workbench is provided with an exhaust fan, a motor, a threaded rod, a connecting block and a dust collecting box. When the staff cleans the workbench, the staff starts the motor and the exhaust fan through the operation panel, and the motor starts to rotate the threaded rod, and the threaded rod rotates the exhaust fan through the connecting block and the connecting plate, so that the exhaust fan moves laterally on the top of the workbench, and the exhaust fan starts to extract the dust on the top of the workbench, and sends the extracted dust into the dust collecting box through the connecting pipe, so that the staff can clean the dust on the top of the workbench conveniently, and avoid the situation where too much dust accumulates and affects the staff's assembly of instruments.

[0004] Based on the above, when assembling smart meters, it is often necessary to perform soldering operations on various high-precision electronic components such as circuit boards inside the smart meters, and use electric soldering irons to spot-weld the welding points on the circuit boards. When using electric soldering irons, one end of the electric soldering iron will remain high in temperature for a long time after use. In order to prevent burns from electric soldering irons during work, the soldering iron stand for placing the electric soldering iron is often placed at the corner of the table, away from the active area of ​​the hands of the staff. When spot-welding the circuit boards inside the smart meters, in order to avoid light obstruction, the welding points on the circuit boards can be illuminated without obstruction. To spot weld the circuit board, the staff needs to pull the telescopic desk lamp to the appropriate position above the circuit board and adjust the irradiation angle, and then take the soldering iron from the soldering iron rack at the corner of the table to spot weld the welding points on the circuit board. When the staff is short and their arms are not long enough, they need to stand up and lean forward to get the soldering iron, and they also need to stand up to pull down the telescopic desk lamp above the table. When the soldering iron needs to be reused for spot welding, the staff needs to repeatedly stand up to get the soldering iron and adjust the telescopic desk lamp. The process is cumbersome and laborious, which affects work efficiency. Utility Model Content
