Description

Technical Field

[0001] The invention belongs to the technical field of detection equipment, and in particular relates to a defective inductor tin slag detection machine. Background Art

[0002] The inductor tin slag defect detection machine is a special equipment used to detect whether there is tin slag defect in the inductor during the welding process. In the production process of the inductor, the welding link may produce tin slag residue, which will affect the performance and quality of the inductor, such as causing short circuit, signal interference and other problems. The detection machine uses high-precision sensors and advanced detection algorithms to identify these defective products, such as the inductor tin slag defect detection machine proposed in the patent publication number CN117949463A.

[0003] In the above patent, the tin slag of the inductor is only inspected from one side, resulting in incomplete inspection and missed inspection, which affects the accuracy of inspection. In order to meet the requirements of the production plan, the rotation speed of the inductor is relatively fast during the inspection, which makes the optical frame rate of the optical camera set higher. If the rotation speed is too fast and the camera frame rate is low, the image capture of the surface area of ​​the inductor will be incomplete, affecting the inspection quality. Conversely, if the rotation speed is too slow, it will affect the inspection efficiency. Maintaining the high frame rate working mode of the optical camera for a long time will cause the sensor in the optical camera to perform a large number of photoelectric conversion operations in a short period of time. Frequent photoelectric conversion will cause the pixel unit in the sensor to be continuously active, accelerating pixel aging. Pixel aging is manifested as problems such as decreased pixel responsiveness and increased dark current. Dark current refers to the current still generated by the pixel unit in the absence of light. As the dark current increases, the noise in the image will increase, thereby affecting the image quality. The optical camera is equipped with mechanical devices such as autofocus and zoom. When working at a high frame rate, in order to ensure the clarity of the image, these mechanical parts need to be adjusted more frequently. Frequent mechanical movement increases the wear of the mechanical parts and affects the service life of the optical camera. Summary of the invention

[0048] The PLC controller 10 is fixedly mounted on the outer wall of the optical detection mechanism 4, and is electrically connected to the flip support mechanism 2, the flip power mechanism 3, the optical detection mechanism 4, the guide feeding mechanism 5, the material collecting mechanism 6, the automatic counting mechanism 7 and the detection speed and frame rate self-regulating mechanism 8 respectively.

[0049] The operating principle of the present invention is described as follows: the motor rotating assembly 23 on the outer wall of the upper end of the placement tube 22 is controlled by the PLC controller 10 to work, and the motor rotating assembly 23 drives the upper end cover 24 to move, so that the upper end of the placement tube 22 is exposed, and the cylindrical inductor to be tested is placed in the placement tube 22. After the placement is completed, the clamping round shell 27 connected to the lower end cover 24 is controlled by the PLC controller 10 to start working, and the torque motor 29 drives the bevel gear assembly 210 to drive multiple clamping screws 28 to rotate synchronously. The multiple clamping plates 211 move toward each other through the threaded sleeve effect of the clamping screws 28 and the clamping plates 211, thereby performing the inductor testing. The inductor 29 is clamped firmly until the rotation torque of the torque sensor reaches the threshold value, and the PLC controller 10 controls the torque motor 29 to stop the action. The PLC controller 10 then controls the electric push rod 25 on the lower side to push the inductor to move up and extend out of the upper end of the placement tube 22. The optical detection camera 45 first takes a picture of the top of the inductor for detection. After the detection is completed, the optical detection camera 45 is driven by the arc-shaped electric slide rail 44 to move to the side of the inductor for shooting and detection. At the same time, the rotating motor 26 drives the inductor to rotate, so that the optical detection camera 45 performs a comprehensive detection on the side of the inductor. After the detection is completed, the electric push rod 25 is controlled to drive the inductor to be retracted and placed. The motor rotating assembly 23 at the upper end is controlled to reset the upper end cover 24 and close the placement tube 22 again. The PLC controller 10 controls the servo motor 33 to work for 3s. The servo motor 33 drives the reciprocating screw 32 to rotate. The threaded sleeve connection between the reciprocating screw 32 and the reciprocating plate 34 enables the reciprocating plate 34 to cooperate with the reciprocating rod 35 to drive the transmission rack 36 to move a fixed distance. The meshing action of the transmission rack 36 and the transmission gear 37 drives the flip shaft 21 to drive the placement tube 22 to rotate 180 degrees, so that the inductor is inverted. The PLC controller 10 then controls the torque motor 29 that was originally started to reset, releases the limit lock on the inductor, and makes the inductor inverted. The inductor is moved to the clamping circular shell 27 currently on the lower side, and the torque motor 29 in the current clamping circular shell 27 is controlled to move, and the inductor is fixed again, and the above action is repeated, so that the end cover 24 currently located at the upper end is moved away, and the other end and side of the inductor are detected again in cooperation with the electric push rod 25 and the rotating motor 26, so as to realize the comprehensive detection of the inductor and improve the detection accuracy. The PLC controller 10 then controls the electric telescopic rod 43 to drive the optical detection camera 45 to move upward, and drives the optical detection camera 45 to move to the detection station of the next group of inductors through the horizontal electric slide rail 42, so as to carry out continuous detection work and improve the detection efficiency.

[0050] Before the detection, the push-pull plate 88 at the corresponding position is manually pressed based on the number of inductors to be detected. Specifically, the lower the push-pull plate 88 is, the more inductors are detected. After pressing the push-pull plate 88, the push-pull plate 88 cooperates with the push-pull rod 87 to overcome the elastic force of the retaining spring 811 to drive the trigger switch 810 to move until the push-pull plate 88 contacts the positioning magnetic block 89. The magnetic attraction of the positioning magnetic block 89 on the push-pull plate 88 is greater than the rebound force of the retaining spring 811, so that the placement position of the trigger switch 810 is fixed, and the PLC controller 10 then controls the stepper motor 83 to operate, and the stepper motor 83 drives the linkage screw 82 to rotate. Through the threaded sleeve effect of the linkage screw 82 and the linkage seat 84, the linkage seat 84 drives the feedback conductive contact piece 86 to slide on the feedback resistor rod 85 until the trigger plate 812 on the outer wall of the linkage seat 84 presses on the extended trigger switch 810. At this time, the PLC controller 10 controls the stepper motor 83 to stop operating. When the inductor to be detected The larger the number of sensors, the greater the sliding distance of the feedback conductive contact 86 on the feedback resistor rod 85, so that the access resistance of the feedback resistor rod 85 is smaller, and the feedback conductive contact 86 and the feedback resistor rod 85 are connected in series to the power supply circuit of the rotating motor 26, and the rotating motor 26 is a DC motor, so that the power supply current of the rotating motor 26 is larger, the rotation speed of the rotating motor 26 is increased, and the detection rate is increased. When the linkage screw 82 rotates, it cooperates with the reduction gear box 814 to drive the frame rate adjustment knob 813 to rotate synchronously for adjustment [the frame rate of the optical detection camera is controlled by the internal clock signal, and the frame rate adjustment knob 813 adjusts the frame rate by changing the frequency of the clock signal. When the frame rate adjustment knob 813 is turned, it will change the value of a variable resistor or capacitor in the internal circuit of the optical detection camera 45. The change in the value of these components will affect the frequency of the clock generator], thereby synchronously improving the detection frame rate of the optical detection camera 45 to ensure the detection quality;

[0051] When the inductor detection is completed, the inductor is retracted into the placement tube 22 again, and the placement tube 22 is reset and rotated 180 degrees again by flipping the power mechanism 3. At this time, the PLC controller 10 controls the motor rotation assembly 23 on the lower side to drive the end cover 24 on the lower side to remove the lower end of the placement tube 22, and makes the torque motor 29 fixed to the inductor move in the reverse direction, releases the limit lock on the inductor, and makes the inductor automatically fall on the feeding trough 53 under the gravity of the inductor, and the PLC controller 10 controls the power supply equipment to supply power to the suction electromagnetic plate 56, and the suction electromagnetic plate 56 is energized to generate a magnetic force opposite to the suction permanent magnet plate 57, so that the feeding trough 53 overcomes the elastic force of the elastic telescopic rod 54 and tilts and deflects with the rotation connection point of the U-shaped bracket 51 and the deflection block 52 as the deflection position, so that the feeding trough 53 is tilted, and then slides along the feeding trough 53 into the collection box 65 under the gravity of the inductor;

[0052] Specifically, the PLC controller 10 first puts the qualified inductors into the feeding trough 53, and then puts them into the collection box 65 of qualified products. After completing the collection of qualified products, the PLC controller 10 controls the driving motor 61 to drive the mounting plate 62 to rotate 180 degrees, so that the collection box 65 of unqualified products moves to the unloading port of the feeding trough 53. The PLC controller 10 then controls the end cover 24 at the lower end of the placement cylinder 22 corresponding to the unqualified inductors to open, collects the unqualified inductors, and realizes the rapid sorting of qualified and unqualified inductors.

[0053] When collecting inductors, the PLC controller 10 controls the inductors to be lowered and fed one by one. The PLC controller 10 controls the working time of the reduction motor 73 based on the number of lowered inductors. For example, if there is one inductor to be collected, the reduction motor 73 is controlled to work for 0.5s. The reduction motor 73 drives the transmission screw 72 to rotate. The threaded sleeve of the transmission screw 72 and the moving plate 74 enables the moving plate 74 to move in the statistical shell 71. When the pressing round head 76 at the lower end of the moving plate 74 presses on the feed start switch 75, the PLC controller 10 controls the current collection. The feeding electric slide rail 63 at the lower end of the collection box 65 moves for 5 seconds, so that the collection box 65 is pushed forward, so that the inductors are placed in the collection box 65 in an orderly manner, avoiding the problem of unreasonable collection caused by the inductors piling up in a single position in the collection box 65. When the number of collected inductors in the collection box 65 reaches the standard, the moving distance of the moving plate 74 is sufficient, so that the moving plate 74 will press on the termination switch 77, and the PLC controller 10 sends a wireless signal to the staff's receiving terminal to remind the staff to replace the current collection box 65 and perform subsequent processing on the collected inductors.
