Description

Technical Field

[0001] The utility model relates to the technical field of resistor processing, in particular to a resistor shoveling mechanism. Background Art

[0002] When processing leadless resistors, iron caps need to be assembled at both ends of the resistor rod body. Since the individual resistors are relatively small, it is difficult to clamp the resistors and the iron caps. In addition, since resistors are used in circuits, the required precision is also relatively high. However, most of the assembly work on the market is done manually, and long-term work can easily cause fatigue, so the work efficiency is relatively low, and the labor cost is also relatively high.

[0003] The applicant previously disclosed a resistor assembly mechanism in CN216119759U, including a machine base, a rotating wheel and a rotating wheel driving member for driving the rotating wheel to rotate are rotatably arranged on the machine base, a transverse groove is arranged on the outer wall of the rotating wheel, and a plurality of transverse grooves are arranged at intervals along the circumference of the rotating wheel, and the machine base is also provided with a resistor rod loading station for feeding the resistor rod into the transverse groove and an iron cap loading station for feeding the iron cap into the transverse groove. There are two iron cap loading stations, one on the left and one on the right, respectively arranged on both sides of the resistor rod loading station, and the rotation of the rotating wheel can drive the transverse groove to pass through the resistor. The rod loading station and the iron cap loading station are provided with a push rod at both ends of each transverse groove, and the push rod is arranged in the transverse groove for transverse sliding. The machine base is also provided with a push piece for pushing the push rod to slide, and also includes a reset structure for driving the push rod to reset and a limit structure for limiting the push rod from leaving the transverse groove; the rotating wheel is also provided with an annular groove, which is arranged around the rotating wheel. The machine base is also provided with a discharging station, and the discharging station is provided with a discharging trough and a guide shovel. One end of the guide shovel is located in the annular groove, and the other end extends to the inlet end of the discharging trough. The rotating wheel can rotate relative to the guide shovel. In the above-mentioned resistor assembly mechanism, there is no resistor qualification detection step, and the position of the guide shovel is always fixed. Regardless of whether the resistor is qualified or not, it will be shoveled off by the contacted guide shovel, and subsequent manual detection and screening is required to determine whether the resistor assembly is qualified. Summary of the invention

[0004] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a resistor shoveling mechanism, which adopts fully automated mechanical operation, improves the screening efficiency of qualified resistors, and reduces labor costs.

[0005] The technical solution of the utility model is: a resistor shoveling mechanism, including a discharge trough and a shovel tool arranged on the discharge trough, the shovel head of the shovel tool is used to shovel out the resistor stuck in the horizontal groove of the rotating wheel, and also includes a resistor detector, the resistor detector has a pair of detection blocks, the pair of detection blocks are respectively used to contact the iron caps located at both ends of the resistor rod, the shovel tool can slide back and forth so that the shovel head can enter and exit the rotating wheel, and after the resistor detector detects that the resistor assembly is unqualified, the driving part controls the shovel tool to slide backward and drives the shovel head to retract and leave the rotating wheel.

[0006] By adopting the above technical solution, the rotating wheel rotates, and a pair of detection blocks are respectively used to contact the iron caps located on the rotating wheel and at both ends of the resistor rod. After the resistor is tested to be qualified, the shovel head of the shovel is extended to the front position, and the rotating wheel rotates relative to the shovel head. The shovel head contacts the resistor on the rotating wheel and can automatically shovel out the resistor, and then discharge it from the discharge chute; after detecting that the resistor assembly is unqualified, the driving part drives the shovel head to retract and leave the rotating wheel. At this time, the unqualified resistor will not be shoveled out, and the iron cap and the resistor rod will continue to be pressed and assembled again as the rotating wheel rotates.

The driving member is a motor, a gear is provided on the output shaft of the motor, and a rack is provided on the bottom surface of the shovel seat.

[0017] like Figure 1-3 As shown, a resistor shoveling mechanism of the utility model includes a discharge trough 1, a shovel 2 arranged on the discharge trough 1, the shovel head 2a of the shovel 2 is used to shovel out the resistor stuck in the horizontal groove of the rotating wheel, and the rotating wheel rotates relative to the shovel head 2a during shoveling, and also includes a resistor detector, the resistor detector has a pair of detection blocks 31, the pair of detection blocks 31 are respectively used to contact the iron caps located at both ends of the resistor rod, and the pair of detection blocks 31 are also connected to the detector via wires, the shovel 2 can slide back and forth so that the shovel head 2a enters and exits the rotating wheel, and after the resistor detector detects that the resistor assembly is unqualified, the driving part controls the shovel 2 to slide backward and drives the shovel head 2a to retract and leave the rotating wheel. The detection block can be swung and reset, and it can swing relatively when subjected to external force, and can reset itself after swinging, so that the detection block always keeps the state of fitting the iron cap.

[0018] Specifically, the shovel surface 2a1 on the shovel head 2a is arc-shaped or inclined, and the shovel surface 2a1 is used to contact the resistor being shoveled.

[0019] Specifically, the middle part of the shovel head 2a is hinged on the shovel handle 2b, and the bottom of the shovel head 2a is pulled by a tension spring 2c, so that the top of the shovel head 2a swings forward to press the rotating wheel, and the shovel surface 2a1 is located on the top of the shovel head 2a.

[0020] Specifically, the shovel 2 includes a pair of shovel heads 2a, which are installed on the shovel seat 21. The driving member is a motor, and a gear 41 is provided on the output shaft of the motor. A rack 42 is provided on the bottom surface of the shovel seat 21. The rack 42 is arranged along the front and rear directions and is also exposed on the bottom surface of the discharge trough 1. The rack 42 is meshed with the gear 41. The rotation of the gear 41 can drive the rack 42 meshed with it to drive the shovel 2 to slide forward and backward.

[0021] Specifically, the motor is a stepper motor.

[0022] Specifically, a sensor A51 and a sensor B52 are provided on the side wall of the discharge chute 1 . The sensor A51 is used to sense the forward sliding position of the shovel 2 , and the sensor B52 is used to sense the backward sliding position of the shovel 2 .

[0023] The working principle of the shoveling material of the utility model:

[0024] The wheel rotates, and a pair of detection blocks 31 are used to contact the iron caps located on the wheel and at both ends of the resistor rod. After the resistor is tested to be qualified, the shovel head 2a of the shovel 2 is extended in the front position, and the wheel rotates relative to the shovel head 2a. The shovel head 2a contacts the resistor on the wheel and can automatically shovel out the resistor, and then it is discharged from the discharge chute 1; and after detecting that the resistor assembly is unqualified, the motor drives the gear 41 to rotate, so that the rack 42 meshing with it drives the shovel 2 to slide backward, driving the shovel head 2a to retract and leave the wheel. At this time, the unqualified resistor will not be shoveled out, and the iron cap and the resistor rod will continue to be pressed and assembled again as the wheel rotates. The arc-shaped or inclined shovel surface can better shovel the resistor out of the horizontal groove.

[0025] When the shovel 2 slides forward and the shovel head 2a contacts the resistor, the tension spring 2c can ensure that the shovel head 2a is always in elastic contact with the resistor and can also play a buffering role during contact to avoid wear and loss of the resistor.

[0026] The use of fully automated mechanical operation improves the screening efficiency of qualified resistors and reduces labor costs.
