DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-Figure 4 As shown, an electronic component painting device includes a material holding box 1, a fixing frame 2 is provided on the material holding box 1, and a fixing plate 3 is provided on the fixing frame 2, a clamping plate 5 is installed on the fixing plate 3 through a connecting component 4, a spray pipe 6 is provided on the fixing frame 2 through a lifting mechanism, and the lifting mechanism includes a fixing seat 8, a guide rod 9, a servo motor 10, a screw rod 11, a first lifting rod 12 and a second lifting rod 13, a collecting structure 7 is provided on the fixing frame 2, a driving pump 15 is installed on the material holding box 1, and the driving pump 15 is connected to the spray pipe 6 through a pipeline, the spray pipe 6 is provided with a nozzle, an assembly groove 14 is provided on the fixing frame 2, and the connecting component 4 includes a movable rod, a spring and a stopper, the movable rod passes through the fixing plate 3, and the movable rod is fixedly connected to the clamping plate 5, the spring It is sleeved on the movable rod, and the spring is located between the fixed plate 3 and the clamping plate 5, the block is fixed at the end of the movable rod, and the guide rod 9 and the screw rod 11 are respectively installed between the two groups of fixed seats 8. The servo motor 10 is arranged on the fixed seat 8 for installing the screw rod 11. The first lifting rod 12 and the second lifting rod 13 are fixed to the end of the spray tube 6, and the first lifting rod 12 is sleeved on the guide rod 9, and the second lifting rod 13 is threadedly connected with the screw rod 11. The lifting mechanism is used to move the spray tube 6, and the spraying operation can be achieved without manual control, which improves the flexibility of use. It is driven by the servo motor 10 and the screw rod 11. There is a self-locking effect between the screw rod 11 and the second lifting rod 13, which can ensure the stability of the spray tube 6 when it is not in use.

[0020] When the device is used to spray paint the circuit board, the clamping plate 5 is moved toward both sides, and the clamping plate 5 moves on the fixed plate 3 through the movable rod in the connecting component 4. In this process, the spring is compressed, and then the circuit board is placed between the two clamping plates 5. After the clamping plate 5 is released, the clamping plate 5 is firmly clamped on the circuit board under the action of the spring, thereby ensuring the stability of the circuit board. Then the driving pump 15 is started, and the paint in the material storage box 1 is pressed into the spray pipe 6 and sprayed from the nozzle. At the same time, the servo motor 10 on the corresponding fixed seat 8 in the lifting mechanism is started. The servo motor 10 runs with the screw rod 11, thereby driving the second lifting rod 13 to move, and the spray pipe 6 moves together. At the same time, the first lifting rod 12 at the other end of the spray pipe 6 moves along the guide rod 9 to ensure the movement stability of the spray pipe 6. The spray pipe 6 moves on the fixed frame 2 to realize the spraying operation of the circuit board, and the excess paint flows into the collecting structure 7, and is finally collected and entered into the material storage box 1 for recycling, thereby avoiding waste and reducing the cost of use.

[0021] Through the above implementation scheme, the collecting structure 7 includes a collecting bucket 701, a guide tube 704 and a filter assembly 706. The collecting bucket 701 is fixedly connected to the guide tube 704. The filter assembly 706 is installed inside the collecting bucket 701, and the lower end of the filter assembly 706 is located in the guide tube 704. The collecting structure 7 also includes a mounting block 702, a mounting screw 703 and a circular groove 705. The mounting block 702 is fixed to the fixing seat 8 at the lower end of the fixing frame 2 by the mounting screw 703, and the mounting block 702 is fixedly connected to the collecting bucket 701. The back of the collecting bucket 701 is inserted into the assembly groove 14. The circular groove 705 is arranged at the position where the inside of the collecting bucket 701 is connected to the guide tube 704. The filter assembly 706 includes a filter frame 7061, a filter screen 7062, a weight-increasing rod 7063 and a ball 7064. The filter screen 7062 is fixed on the filter frame 7061, the weight-increasing rod 7063 is fixedly connected to the ball 7064, and the weight-increasing rod 7063 is installed through the filter frame 7061, and a collecting structure 7 is arranged on the fixing frame 2, which can collect excess paint during spraying, and the collected paint can be used again, avoiding waste and reducing the cost of use. The collecting structure 7 is detachable and easy to disassemble. The filter assembly 706 is installed at the guide pipe 704 through the circular groove 705, which can play a filtering effect in the process of collecting paint and prevent impurities from entering the material box 1. The weight-increasing rod 7063 and the ball 7064 are arranged in the filter assembly 706. The weight-increasing rod 7063 ensures the stability of the entire assembly, and the ball 7064 facilitates the removal of the filter assembly 706 for replacement and cleaning.

[0022] When installing the collecting structure 7, the back of the collecting bucket 701 is set into the assembly groove 14, and the mounting screws 703 are used to fix the mounting block 702, so that the collecting bucket 701 is installed. Then, the filter assembly 706 is lifted by the ball 7064, and the filter assembly 706 is placed in the circular groove 705. The lower end of the weight-increasing rod 7063 is located in the guide tube 704 to play the role of weight-increasing and auxiliary fixation. After the collecting structure 7 is installed and put into use, the excess paint falls into the collecting bucket 701 and flows toward the guide tube 704, and finally flows into the material holding box 1 from the guide tube 704. During this process, the filter screen 7062 on the filter frame 7061 plays a filtering effect, preventing impurities from entering the material holding box 1, thereby ensuring the cleanliness of the recovered paint. When the filter assembly 706 needs to be removed, it can be quickly taken out through the ball 7064. The structure is simple and the operation is convenient.
