Description

A device for removing impurities on a circuit board

technical field

The utility model relates to a device for removing impurities on a circuit board.

Background technique

The circuit board is the provider of the electrical connection of electronic components. The main advantage of using the circuit board is to greatly reduce the errors of wiring and assembly, and improve the automation level and production labor rate. The production of circuit boards needs to go through the processes of drilling, electroplating, cleaning, drying and green paint in sequence before reaching the finished circuit board.

Among them, after the circuit board is electroplated in the electroplating tank, because there are a lot of impurities (such as small stones, sand, etc.) on the surface of the circuit board, it is necessary to use clean water to remove the impurities on the surface of the circuit board before it can be transported to the subsequent In the circuit board drying process, when cleaning the circuit boards, the workers put the circuit boards in the sink for manual cleaning. However, the output of the circuit boards is large, and many workers are required to operate at the same time, which undoubtedly increases the production of the production process. The cost reduces the production efficiency of the circuit board, so it is not enough to rely on manual cleaning. In addition, after each batch of circuit boards is cleaned, the water in the water tank needs to be replaced, which further reduces the cleaning efficiency of the circuit boards.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the prior art and provide a device for removing impurities on the circuit board which has a compact structure, saves production costs, improves the cleaning efficiency of the circuit board, and saves labor intensity of workers.

The purpose of this utility model is achieved through the following technical solutions: a device for removing impurities on the circuit board, which includes a workbench, a mounting plate and a servo motor, the rear end of the workbench is provided with a column, and the column is provided with Mounting plate, the rotating shaft on the mounting plate is installed with a screw rod, the screw rod is arranged horizontally, a nut is connected to the screw rod, a flat plate is arranged at the bottom of the nut, a vertically arranged cylinder is fixedly installed on the flat plate, and the acting end of the piston rod of the cylinder is fixed. A scraper is provided, the servo motor is fixedly installed on the mounting plate, the output end of the servo motor is connected with one end of the screw rod, and it also includes a controller, and the controller is connected with the servo motor and the cylinder.

The column is arranged vertically to the workbench.

The mounting plate is arranged horizontally.

The utility model has the following advantages: the utility model only needs one worker to take the circuit board, and another worker operates the controller to realize the removal of impurities, which greatly saves the labor intensity of the workers and saves the production cost at the same time. The production efficiency of the circuit board is improved.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described, and the protection scope of the utility model is not limited to the following:

As shown in Figures 1 and 2, a device for removing impurities on a circuit board includes a workbench 1, a mounting plate 2 and a servo motor 3, and the rear end of the workbench 1 is provided with a column 4, and the column 4 Set vertically to the workbench 1, the column 4 is provided with a mounting plate 2, the mounting plate 2 is set horizontally, the rotating shaft on the mounting plate 2 is installed with a screw 5, the screw 5 is set horizontally, the screw 5 is connected with a nut 6, the nut The bottom of 6 is provided with flat plate 7, and the cylinder 8 that is vertically arranged is fixedly installed on flat plate 7, and the action end of the piston rod of cylinder 8 is provided with scraper 9, and scraper 9 is used for sweeping away the impurity on the circuit board surface, and scraper 9 is made of wood to prevent the scraper from scratching the circuit board. As shown in FIGS. 1 and 2 , the servo motor 3 is fixedly installed on the mounting plate 2 , and the output end of the servo motor 3 is connected to one end of the screw rod 5 . As shown in Fig. 1 and Fig. 2, it also comprises controller 10, and described controller 10 is connected with servomotor 3 and cylinder 8, therefore, the worker can control the starting or closing of servomotor 3 through controller 10, and control The servo motor 3 performs forward rotation or reverse rotation, and the controller 10 can also control the extension or retraction of the piston rod of the cylinder 8, which has the characteristics of high degree of automation.

The working process of the utility model is as follows: the worker first puts the circuit board to be cleaned on the table top of the workbench 1, and then controls the piston rod of the cylinder 8 to stretch out, so that the scraper contacts the upper surface of the circuit board, and then controls the servo The motor 3 rotates forward, the servo motor 3 drives the screw 5 to rotate, and the screw 5 drives the nut 6 to move to the left, so that the impurities covered on the surface of the circuit board are removed. In the whole cleaning process, only one worker needs to take the circuit board For the circuit board, another worker can operate the controller to remove the impurities, which greatly saves the labor intensity of the worker, saves the production cost and improves the production efficiency of the circuit board.
