[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 4As shown, this utility model embodiment provides a PCB board transfer device for an SMT production line, including a base 1, a transverse moving mechanism 2, a movable seat 3, a fixed side plate 41, a movable side plate 42, a width adjustment mechanism 5, and a material conveying mechanism 6. The base 1 is provided with a transfer channel 10 for conveying PCB boards. The transverse moving mechanism 2 is disposed in the transfer channel 10, and the movable end of the transverse moving mechanism 2 is connected to the movable seat 3. The transverse moving mechanism 2 is used to drive the movable seat 3 to reciprocate along the width direction of the transfer channel 10. The fixed side plate 41 and the movable side plate 42 are disposed on both sides of the movable seat 3. Two sets of material conveying mechanisms 6 are respectively disposed on the fixed side plate 41 and the movable side plate 42. The material conveying mechanism 6 is used to convey PCB boards. The width adjustment mechanism 5 is connected to the movable side plate 42. The side plate 42 is connected, and the width adjustment mechanism 5 is used to adjust the gap between the movable side plate 42 and the fixed side plate 41. The PCB board to be transported can enter the transfer channel 10 set in the machine base 1 from the previous process. The lateral movement mechanism 2 can drive the movable seat 3 to move back and forth along the width direction of the transfer channel 10 to adjust the position to meet the docking requirements of different inlet and outlet equipment. The fixed side plate 41 and the movable side plate 42 are respectively installed on both sides of the movable seat 3. The fixed side plate 41 and the movable side plate 42 are respectively provided with a material conveying mechanism 6. After the PCB board enters the transfer channel 10, the material conveying mechanism 6 can drive the PCB board to move along the direction of the transfer channel 10. The width adjustment mechanism 5 can adjust the distance between the movable side plate 42 and the fixed side plate 41 to adapt to the transport of PCB boards of different widths, thereby improving the adaptability of the transfer device to transport PCB boards of various specifications.

[0038] like Figure 2 As shown, a first sensor 71 and a second sensor 72 are respectively provided on the fixed side plates 41 at both ends of the material conveying mechanism 6. The first sensor 71 is used to detect whether the PCB board has arrived into the transfer channel 10, and the second sensor 72 is used to detect whether the PCB board has left the transfer channel 10. The first sensor 71 is used to detect whether the PCB board has entered the transfer channel 10. When the PCB board is detected to have reached the designated position, the controller can start the material conveying mechanism 6 to ensure that the conveying cycle is synchronized with the upstream process. The second sensor 72 is located at the exit of the transfer channel 10 and is used to determine whether the PCB board has successfully left the current transfer area. This allows the controller to confirm that the circuit board has completed the transfer operation and is ready to receive the next workpiece. This setting not only improves the conveying efficiency of the PCB board, but also avoids interference to subsequent processes caused by abnormal situations such as missing boards or jammed boards, effectively improving the stability of the production line operation.

[0039] like Figure 4As shown, the lateral moving mechanism 2 further includes a first motor 21, a first lead screw 22, a first threaded seat 23, a slide rail 24, and a slider 25.

The first threaded seat 23 is sleeved on the first lead screw 22. The top of the first threaded seat 23 is connected to the moving seat 3. The first threaded seat 23 is used to drive the moving seat 3 to move along the extension direction of the slide rail 24 as the first lead screw 22 rotates. This arrangement facilitates the adjustment of the inlet and outlet positions of the PCB board in the transfer channel 10, meets the different requirements of upstream and downstream equipment for the board entry position, and thus improves the adaptability between the transfer device and the production line.

[0040] like Figure 3 As shown, the width adjustment mechanism 5 further includes a support plate 51, a second lead screw 52, ​​a third lead screw 53, and an adjusting handwheel 54. The support plate 51 is mounted on a movable seat 3 at the side end of the movable side plate 42. Second threaded seats 55 are respectively provided on both sides of the movable side plate 42. The second lead screw 52 and the third lead screw 53 are respectively threadedly connected to the second threaded seats 55, and the ends of the second lead screw 52 and the third lead screw 53 are connected via a second pulley assembly 521. The adjusting handwheel 54 is connected to the second lead screw 52 and is used to drive the second lead screw 52 to rotate. The operator can rotate the adjusting handwheel 54 to drive the second lead screw 52 to rotate. The second lead screw 52 is threadedly connected to the second threaded seat 55, and its end drives the third lead screw 53 to rotate synchronously via the second pulley assembly 521. The third lead screw 53 then drives the second threaded seat 55 on the other side to move, thereby realizing the parallel movement of the movable side plate 42 in the width direction and avoiding uneven force or skewing at both ends.

[0041] like Figure 3 As shown, the width adjustment mechanism 5 further includes a linear bearing 57 and a guide slide rod 56. The linear bearing 57 is disposed on the movable side plate 42, and the guide slide rod 56 passes through the linear bearing 57. One end of the guide slide rod 56 is connected to the support plate 51, and the other end is connected to the fixed side plate 41. The linear bearing 57 and the guide slide rod 56 can improve the smoothness of movement of the movable side plate 42 and avoid deviation or shaking that affects the adjustment accuracy.

[0042] like Figure 2 and Figure 3As shown, the material conveying mechanism 6 further includes a second motor 61, a conveyor belt 62, a driving pulley 63, and a driven pulley 64. Driven pulleys 64 are respectively provided at both ends of the movable side plate 42 and the fixed side plate 41. The output shaft of the second motor 61 is connected to the driving pulley 63. The second motor 61 is used to drive the driving pulley 63 to rotate. The conveyor belt 62 is sleeved between the driving pulley 63 and the driven pulley 64. The conveyor belt 62 is used to abut against the end of the PCB board and conveys the PCB board to the outside of the transfer channel 10 as the driving pulley 63 rotates.

[0043] like Figure 2 and Figure 3 As shown, it further includes a tension adjusting wheel 65. The movable side plate 42 and the fixed side plate 41 are respectively provided with a sliding groove 400. The tension adjusting wheel 65 can move up and down along the extension direction of the sliding groove 400. The tension adjusting wheel 65 abuts against the surface of the conveyor belt 62, thereby applying appropriate tension to the conveyor belt 62 and avoiding deviation or slippage caused by the loosening of the conveyor belt 62.

[0044] like Figure 1 and Figure 2 As shown, a transparent window 100 is provided on the top surface of the base 1 above the transfer channel 10 so that the operator can observe the conveying and operation of the PCB board in real time, and promptly detect abnormal problems such as board jamming and offset, thereby improving the operational safety and maintenance response efficiency of the equipment.

[0045] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
