[0002] With the continuous development of electronic technology, circuit boards are increasingly widely used in various electronic devices. In order to improve the performance and reliability of electronic products, the assembly accuracy requirements of components on circuit boards are getting higher and higher. As a key device in the manufacturing process of modern electronic products, the main function of an automatic chip mounter is to accurately place various electronic components on the circuit board. However, in the actual production process, impurities such as dust and oil stains may adhere to the surface of the circuit board. These impurities will not only affect the working efficiency of the chip mounter, but also may cause poor contact between the components and the circuit board, thereby affecting the quality and performance of the final product.

[0003] To solve this problem, we propose an automatic circuit board chip mounting device. This automatic chip mounting device can clean the surface of the circuit board before the chip mounting operation to remove possible dust and impurities, ensuring the chip mounting quality. Summary of the Utility Model

[0018] Embodiment 1: An automatic circuit board chip mounting device, as Figures 1-4 shown, includes a mounting base 1, a first mounting frame 2, a second mounting frame 3, a chip mounting structure 4, a placement plate 5, conveying rollers 6, a conveying belt 7, a driving motor 8, a cleaning assembly, and a heating assembly. The right part of the mounting base 1 is fixedly connected to the first mounting frame 2, and the left part of the mounting base 1 is fixedly connected to the second mounting frame 3. The second mounting frame 3 is attached to and fixedly connected to the first mounting frame 2. Transparent observation windows are provided on both the front and rear sides of the second mounting frame 3. The upper side inside the second mounting frame 3 is fixedly connected to the chip mounting structure 4, and the rear part inside the second mounting frame 3 is fixedly connected to the placement plate 5. Both the left and right parts of the mounting base 1 are rotatably connected to the conveying rollers 6, and the conveying belt 7 is sleeved between the left and right conveying rollers 6. The conveying belt 7 is provided with equally spaced protruding plates for limiting and separating the circuit boards. The right rear part of the mounting base 1 is fixedly connected to the driving motor 8, and the output shaft of the driving motor 8 is fixedly connected to the right conveying roller 6. A cleaning assembly for cleaning the circuit board is provided on the first mounting frame 2, and a heating assembly for heating the circuit board is provided on the mounting base 1.

[0019] When using this device, the staff places the circuit board to be chipped on the conveying belt 7, limits and separates the circuit board through the protruding plates, and then starts the driving motor 8. The output shaft of the driving motor 8 rotates to drive the right conveying roller 6 to rotate. The conveying roller 6 rotates to drive the conveying belt 7 to rotate, and the conveying belt 7 rotates to convey the circuit board to the left. When the circuit board is conveyed to the lower part of the first mounting frame 2 to the left, the cleaning assembly cleans the dust and impurities on the surface of the circuit board. The cleaned circuit board is continuously driven by the conveying belt 7 to move leftward. When the circuit board moves to the lower part of the second mounting frame 3 to the left, the chip mounting structure 4 grabs the components on the placement plate 5 to chip the circuit board. After chipping is completed, the conveying belt 7 controls the circuit board to continue moving leftward, and then the heating assembly heats the circuit board, thereby fixing the components on the circuit board. When this device is no longer in use, the staff turns off the driving motor.

[0020] Embodiment 2: On the basis of Embodiment 1, as Figure 1 and Figure 3As shown, the cleaning component includes a rotating shaft 9, a cleaning roller 10, a pulley 11, a flat belt 12, a liquid storage tank 13, a permeation plate 14, and a hair dryer 141. The right part of the first mounting bracket 2 is rotatably connected to the rotating shaft 9. The cleaning roller 10 is fixedly connected to the rotating shaft 9. Pulleys 11 are fixedly connected to the rear part of the rotating shaft 9 and the rear part of the conveying roller 6 on the right side. The flat belt 12 is sleeved between the left and right pulleys 11. The liquid storage tank 13 is fixedly connected to the upper right part of the first mounting bracket 2. The permeation plate 14 is communicated with the lower side of the liquid storage tank 13. The lower part of the permeation plate 14 is of an arc structure and fits the surface of the cleaning roller 10. The hair dryer 141 is fixedly connected inside the first mounting bracket 2.

[0021] When using this device, the rotation of the conveying roller 6 on the right side will drive the rotation of the rotating shaft 9 through the cooperation of the pulley 11 and the flat belt 12. The rotation of the rotating shaft 9 drives the rotation of the cleaning roller 10. When the circuit board moves leftward to below the cleaning roller 10, the rotating cleaning roller 10 can wipe the surface of the circuit board. The cleaning liquid in the liquid storage tank 13 will also flow out through the permeation plate 14 and then be taken away by the rotating cleaning roller 10 to clean the surface of the circuit board, thereby improving the cleaning effect. After being wiped and cleaned, the circuit board continues to move leftward and then is dried by the hair dryer 141 to avoid moisture residue on the surface of the circuit board affecting the chip mounting effect.

[0022] As Figure 1 and Figure 4 As shown, the heating component includes a fixing bracket 15 and a heater 16. Two fixing brackets 15 that are symmetrically arranged front and rear are fixedly connected to the left part of the mounting base 1. The heater 16 is fixedly connected between the front and rear fixing brackets 15.

[0023] When using this device, after the chip mounting structure 4 completes the chip mounting operation on the circuit board, the conveying belt 7 continues to drive the circuit board to move leftward. When the circuit board moves leftward to below the heater 16, the circuit board can be heated by the heater 16, so that the components are fixed on the circuit board.
