Specifically, the sensor 510 is an optical sensor 510.

[0038] It should be noted that the sensor 510 is movably arranged on the rack 100, and the sensor 510 is adjusted in position by a moving assembly to adapt to conveying wheels 300 and lead frames 10 of multiple specifications. Specifically, the moving assembly can be a slide rail and slide block structure, a lead screw structure, an electric structure, etc.

[0039] In some specific embodiments of the utility model, the deviation rectifying assembly 520 comprises: a first deviation rectifying wheel 521, the first deviation rectifying wheel 521 is arranged on the rack 100;Second deviation rectifying wheel 522, second deviation rectifying wheel 522 is movably arranged on the rack 100, second deviation rectifying wheel 522 and first deviation rectifying wheel 521 correspond to each other, lead frame 10 is arranged between first deviation rectifying wheel 521 and second deviation rectifying wheel 522, first deviation rectifying wheel 521 and second deviation rectifying wheel 522 are pressed tightly to change the conveying direction of lead frame 10;Driving part 523, driving part 523 is connected with second deviation rectifying wheel 522, and driving part 523 is used to drive second deviation rectifying wheel 522 to move along the direction close to and away from first deviation rectifying wheel 521.

[0040] As shown in Figure 3 The first deviation rectifying wheel 521 and the second deviation rectifying wheel 522 are relatively arranged along the vertical direction, and the second deviation rectifying wheel 522 is movably arranged on the rack 100 by the driving part 523. It should be noted that in the present specific embodiment, the first deviation rectifying wheel 521 is fixedly arranged on the rack 100, so that when working, the driving part 523 drives the second deviation rectifying wheel 522 to move towards the direction close to the first deviation rectifying wheel 521, so as to clamp the lead frame 10 between the first deviation rectifying wheel 521 and the second deviation rectifying wheel 522.

[0041] In some specific embodiments of the utility model, two deviation rectifying assemblies 520 are symmetrically arranged along the axial direction of the conveying wheel 300, as shown in Figure 2 Two deviation rectifying assemblies 520 on the same side of the conveying wheel 300 are symmetrically arranged along the left-right direction, that is, two deviation rectifying assemblies 520 are symmetrically arranged at the front and rear ends of the lead frame 10, so as to provide better balance, make the system more stable under movement or load, and reduce unnecessary vibration and swing.

[0042] In some specific embodiments of the utility model, the first deviation rectifying wheel 521 is inclined to the conveying direction of the lead frame 10, and the second deviation rectifying wheel 522 is inclined to the conveying direction of the lead frame 10.

[0043] As shown in Figure 3 Among two deviation rectifying assemblies 520 on the same side of the conveying wheel 300, the first deviation rectifying wheel 521 and the second deviation rectifying wheel 522 on the rear side all have an angle with the conveying direction of the lead frame 10, and the first deviation rectifying wheel 521 and the second deviation rectifying wheel 522 on the front side all have an angle with the conveying direction of the lead frame 10. Specifically, the distance between the two first deviation rectifying wheels 521 on the front and rear sides gradually increases along the conveying direction of the lead frame 10, and the distance between the two second deviation rectifying wheels 522 on the front and rear sides also gradually increases along the conveying direction of the lead frame 10.

[0044] In some specific embodiments of the present invention, the inclination angle of the first correcting wheel 521 is α, wherein 50>α>25. Specifically, the inclination angle of the first correcting wheel 521 is 30°.

[0045] Therefore, if Figure 2 As shown, the lead frame 10 passes between the first deflection correcting wheel 521 and the second deflection correcting wheel 522 after being guided by the conveying wheel 300. When the lead frame 10 deviates forward during the conveying process, the sensor 510 located on the front side detects the edge signal of the lead frame 10, and then controls the corresponding driving member 523 to operate, and the first deflection correcting wheel 521 and the second deflection correcting wheel 522 located on the front side press the front side of the lead frame 10. Since the rolling conveying direction after the first deflection correcting wheel 521 and the second deflection correcting wheel 522 press the lead frame 10 is tilted forward to the pulling conveying direction of the lead frame 10, the lead frame 10 will be rolled and pulled forward while being pulled to the right, so that the lead frame 10 moves forward to achieve deflection correction.

[0046] In some specific embodiments of the present invention, two adjustment mechanisms are further included. Both adjustment mechanisms are arranged on the frame 100. Each correcting mechanism 500 is correspondingly provided with an adjustment mechanism.

The vertical adjustment assembly is disposed on the frame 100 and connected to the correction assembly 520. The vertical adjustment assembly is used to drive the correction assembly 520 to move vertically.

[0049] The lead frame 10 is guided by the conveying wheel 300 and passes between the first deviation correcting wheel 521 and the second deviation correcting wheel 522. When the lead frame 10 deviates forward during the conveying process, the sensor 510 on the front side detects the edge signal of the lead frame 10 and sends the edge signal of the deviation of the lead frame 10 to the driving member 523, so that the driving member 523 on the front side second deviation correcting wheel 522 is controlled to move, the second deviation correcting wheel 522 moves towards the first deviation correcting wheel 521 to press the front side edge of the lead frame 10. Since the rolling conveying direction of the first deviation correcting wheel 521 and the second deviation correcting wheel 522 after pressing the lead frame 10 is inclined forward to the traction conveying direction of the lead frame 10, the lead frame 10 is also tractioned forward while being tractioned rightward, so that the lead frame 10 moves forward to realize deviation correction.

[0050] Similarly, when the lead frame 10 deviates backward during the conveying process, the sensor 510 on the rear side detects the edge signal of the lead frame 10 and sends the edge signal of the deviation of the lead frame 10 to the driving member 523, so that the driving member 523 on the rear side second deviation correcting wheel 522 is controlled to move, the second deviation correcting wheel 522 moves towards the first deviation correcting wheel 521 to press the front side edge of the lead frame 10. Since the rolling conveying direction of the first deviation correcting wheel 521 and the second deviation correcting wheel 522 after pressing the lead frame 10 is inclined backward to the traction conveying direction of the lead frame 10, the lead frame 10 is also tractioned backward while being tractioned rightward, so that the lead frame 10 moves backward to realize deviation correction of the lead frame 10.

[0051] The above embodiment of the utility model is described in detail in combination with the drawings, but the utility model is not limited to the above embodiment, and various changes can be made within the knowledge range of ordinary skilled in the art without departing from the purpose of the utility model.
