[0002] A PCB (Printed Circuit Board) is an indispensable component of electronic equipment. It connects electronic components to each other through different types of circuits to form a complete working circuit.
[0003] PCB boards typically require a conveyor mechanism to transport them to the processing station. However, in actual production, companies often need to process PCB boards of different sizes. The conveyor mechanism usually needs to be equipped with a positioning mechanism to limit the PCB board size. However, the positioning mechanism can only be adapted to PCB boards of a fixed size, resulting in poor adaptability of the positioning mechanism and inability to meet actual production needs.
[0004] Therefore, further improvements are needed. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] See Figures 1-4 The PCB board conveying and positioning mechanism includes a first guide rail 11 and a second guide rail 12. A positioning cavity for placing the PCB board is formed between the first guide rail 11 and the second guide rail 12. The first guide rail 11 and the second guide rail 12 are respectively connected to a first connecting plate 21 and a second connecting plate 22. An adjusting screw 3 is provided between the first connecting plate 21 and the second connecting plate 22. The first connecting plate 21 is provided with a screw sleeve 31 that is connected and cooperates with the adjusting screw 3. The adjusting screw 3 is connected to an electric drive assembly for driving its rotation. By rotating the adjusting screw 3, the screw sleeve 31 drives the first connecting plate 21 and the first guide rail 11 to move back and forth along the axial direction of the adjusting screw 3, thereby increasing or decreasing the width of the positioning cavity. The electric drive assembly can adjust the distance between the first connecting plate 21 and the second connecting plate by cooperating with the adjusting screw 3 and the screw sleeve 31, so that a positioning cavity with an adjustable width can be formed between the first track and the second track to adapt to PCB boards of different widths, improve the adaptability of the equipment, and meet a wider range of production needs.
[0023] Meanwhile, the electric drive assembly can further simplify the adjustment of the positioning cavity width, making it easier for workers to operate, and the adjustment accuracy is higher than that of manual adjustment.
[0024] The conveying and positioning mechanism of this PCB board can be applied to the loading end or unloading end of the PCB processing equipment 9, or it can be applied to both the loading end and unloading end of the PCB processing equipment 9 at the same time.
[0025] Furthermore, the electric drive assembly includes a screw motor 4 and a transmission belt 41. The drive shaft of the screw motor 4 is connected to the adjusting screw 3 via the transmission belt 41, making the installation position of the screw motor 4 more flexible and making better use of the space of the equipment.
[0026] Furthermore, a number of limit switches 42 are distributed between the first connecting plate 21 and the second connecting plate 22. The first connecting plate 21 is provided with a trigger 43. The trigger 43 can cooperate with the limit switches 42 to stop the electric drive assembly from working, so that the first connecting plate 21 and the first track can move to a preset position and then automatically stop moving. This allows users to preset different positioning cavity widths according to production needs.
[0027] Furthermore, a plurality of guide posts 23 are provided between the first connecting plate 21 and the second connecting plate 22. The guide posts 23 are arranged along the width direction of the positioning cavity. The first connecting plate 21 is provided with a guide sleeve 24. The guide sleeve 24 is fitted onto the outside of the guide posts 23 and slides in cooperation with each other. The cooperation between the guide posts 23 and the guide sleeve 24 can improve the stability of the first connecting plate 21 during the movement relative to the second connecting plate 22.
[0028] Furthermore, a first conveyor belt 51 for driving the PCB board to move along the length of the first guide rail 11 is connected to the first guide rail 11. The first conveyor belt 51 is connected to the belt drive assembly 5. The PCB board on the positioning cavity can complete the loading or unloading action through the first conveyor belt 51.
[0029] Furthermore, a second conveyor belt 52 for driving the PCB board to move along the length of the second guide rail 12 is connected to the second guide rail 12. The belt drive assembly 5 and the second conveyor belt 52 are connected by a transmission rod 53. The transmission rod 53 extends along the width of the positioning cavity, so that the force on the left and right ends of the PCB board is more even, and the stability of the conveying positioning mechanism in moving the PCB board is improved.
[0030] Furthermore, a fixed mounting plate 6 is provided on the outer side of the first connecting plate 21. The electric drive assembly and the belt drive assembly 5 are respectively connected and fixed to the fixed mounting plate 6. The fixed mounting plate can play the role of installation and positioning of the electric drive assembly and the belt drive assembly 5, making the overall layout of the equipment more reasonable.
[0031] Furthermore, a lifting plate 7 is provided between the fixed mounting plate 6 and the second connecting plate 22. The lifting plate 7 is connected and fixed to the fixed mounting plate 6 and the second connecting plate 22 respectively. The lifting plate 7 is connected to a lifting device 8 that can drive it to move back and forth vertically. The lifting plate 7 can drive the first guide rail 11 and the second guide rail 12 to move back and forth vertically through the fixed mounting plate 6 and the second connecting plate 22, so that the height of the PCB board can be adapted to the position of the PCB board processing station during the loading and unloading process, thereby improving the smoothness of the PCB board processing equipment during the loading and unloading process.
[0032] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
