Description

Technical Field

[0001] The utility model relates to the technical field of frequency converter copper busbar detection, and more specifically to a frequency converter copper busbar flaw detection device. Background Art

[0002] A frequency converter (VFD) is a power control device that applies frequency conversion and microelectronics technology to control AC motors by varying the motor's operating power supply frequency. It primarily consists of a rectifier, filter, inverter, brake unit, drive unit, detection unit, and microprocessor. The VFD adjusts the output power voltage and frequency by switching internal IGBTs, providing the required power supply voltage based on the motor's actual needs, thereby achieving energy savings and speed regulation. VFDs also offer numerous protection features, such as overcurrent, overvoltage, and overload protection. Copper busbars in VFDs are primarily used to transmit high-frequency or high-current power. After processing, they are inspected for defects using a flaw detector.

[0003] Some existing copper busbar inspection devices can only inspect one side of the busbar, requiring manual flipping, which reduces the inspection efficiency of the equipment. Therefore, to solve the above problem, we propose a frequency converter copper busbar flaw detection device. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a frequency converter copper busbar flaw detection device, which adopts the following technical solutions:

[0008] By adopting the above technical solution, when the equipment is used, the staff places the copper bar on the conveyor belt, and the copper bar is transported by the conveyor belt. The side wall of the bottom frame is set by the correction component. When the conveyor belt transports the copper bar, the correction component can correct the copper bar to the conveying position on the conveyor belt, which is convenient for subsequent precise detection of the equipment. When the copper bar moves to the bottom of the first mounting bracket, the surface of the copper bar is scanned and detected by the scanner, and the copper bar is fixed by the clamping component. Then, the connecting block and the probe are driven to descend synchronously by the third telescopic rod, so that the probe contacts the surface of the copper bar. The ultrasonic flaw detector is operated to further detect the copper bar. When the copper bar is unqualified, the unqualified copper bar is transported to the bottom of the horizontal section of the support plate by the conveyor belt, and then the unqualified products are moved out of the conveyor belt by the picking component, which can play the role of picking the copper bar.

[0009] When one side of the copper bar passes the inspection, the conveyor belt moves the copper bar to the bottom of the second mounting rack, and the copper bar is turned over by the operation of the turning assembly. The turned copper bar is transported to the bottom of the third mounting rack by the conveyor belt, and the scanner, probe and ultrasonic flaw detector in the third mounting rack are used to inspect the other side of the copper bar again. This allows the equipment to inspect both sides of the copper bar, which is beneficial to improving the accuracy of the equipment's inspection results. There is no need for staff to manually turn the copper bar over, which is beneficial to improving the inspection efficiency of the copper bar.

[0010] Furthermore, the correction assembly includes a first cylinder fixedly mounted on the top of the mounting seat, two frames are fixedly mounted on the ends of the piston shafts of the first cylinders, and correction rollers distributed in a linear array are rotatably mounted in the two frames.

[0011] By adopting the above technical solution, when the copper bar is being transported on the conveyor belt, the first cylinder drives the same group of frames and correction rollers to move synchronously, so that the two groups of correction rollers contact the opposite sides of the copper bar, which plays a role in correcting and positioning the copper bar, which is beneficial to maintaining the stability of the copper bar transportation and facilitates subsequent accurate detection of the equipment. The correction rollers are rotatably installed in the frame, which can correct the position of the copper bar without affecting the movement of the copper bar.

[0012] Furthermore, the clamping assembly includes a third cylinder fixedly mounted on both sides of the first mounting frame and the third mounting frame, and the two groups of third cylinder piston shafts slide through the first mounting frame and the third mounting frame respectively, and the ends of the third cylinder piston shafts are fixedly mounted with clamps.

[0013] By adopting the above technical solution, when the copper busbar moves into the first mounting rack or the third mounting rack, the third cylinder drives the same group of clamps to move, so that the two clamps in the same group contact the opposite side of the copper busbar, thereby clamping and fixing the copper busbar, which is conducive to maintaining the stability of the copper busbar detection.

[0014] Furthermore, the flip assembly includes a screw rod rotatably installed in the groove, the top ends of the two screw rods rotate and pass through the second mounting bracket, the side walls of the two screw rods are sleeved with a first support block, the second telescopic rods are fixedly installed on the opposite side of the two first support blocks, the ends of the two second telescopic rods are fixedly installed with a mounting box, the second reduction motors are fixedly installed in the two mounting boxes, the ends of the output shafts of the two second reduction motors are fixedly installed with a rotating column, the opposite ends of the two rotating columns pass through the mounting boxes of the same group, the opposite ends of the two rotating columns are fixedly installed with a fixing plate, the top end of the second mounting bracket is fixedly installed with the first reduction motor, the side wall of the output shaft of the first reduction motor is fixedly sleeved with a driving pulley, the two screws pass through the side walls of the bottom end of the second mounting bracket and are fixedly sleeved with a driven pulley, the driving pulley has two wheel grooves, and a belt is provided between the two driven pulleys and the driving pulley.

[0015] By adopting the above technical solution, when one side of the copper bar is inspected and qualified and conveyed to the bottom of the second mounting bracket, the second telescopic rod drives the same group of mounting box and fixed plate to move synchronously toward the copper bar, so that the two fixed plates contact the opposite side of the copper bar, which can play the role of clamping and fixing the copper bar. Subsequently, the first reduction motor drives the driving wheel to rotate, and the driving wheel rotates synchronously through two belts and two driven wheels. The driven wheel drives the same group of screws to rotate, thereby causing the first support block to slide in the groove on the same side. The two first support blocks carry the same group of second telescopic rods, mounting box and fixed plate to rise synchronously, which can play the role of driving the copper bar to rise. Subsequently, the second reduction motor drives the same group of rotating columns and fixed plates to rotate, which can play the role of flipping the copper bar, so that the equipment can scan and detect both sides of the copper bar, which is beneficial to improving the detection efficiency of the copper bar. When the copper bar is flipped, the first reduction motor rotates in the opposite direction, and then the screw rotates in the opposite direction, so that the copper bar drops onto the conveyor belt for subsequent transportation.

[0016] Furthermore, sliders are fixedly installed on both sides of the two first support blocks, and the inner walls of the two grooves are provided with sliding grooves matching the sliders on the same side. The two rotating columns pass through the side walls of one end of the installation box and are fixedly sleeved with installation disks.

The stabilizing blocks of the same group are fixedly connected to the side opposite to the installation disk on the same side on the side close to the fixed plate on the same side.

[0017] By adopting the above technical solution, when the first support block slides in the groove, the first support block slides with the same group of sliders in the same side slide groove, and the cooperation between the sliders and the slide grooves is conducive to maintaining the sliding stability of the first support block. When the rotating column rotates, the rotating column rotates with the mounting plate and the stabilizing block on the same side, and the stabilizing block slides in the annular groove on the same side. The cooperation between the stabilizing block and the annular groove is conducive to maintaining the stability of the rotation of the fixed plate.

[0019] By adopting the above technical solution, when unqualified products move to the bottom of the horizontal section of the support plate, the electric clamp is driven downward by the first telescopic rod, and the product is clamped by the electric clamp. Then, the electric clamp and the product are driven to rise synchronously by the first telescopic rod, and then the second support block is driven to slide in the installation groove by the second cylinder. The second support block moves synchronously with the first telescopic rod and the product, so that the product is moved out from above the conveyor belt, which can be used for picking.

[0020] Furthermore, a mounting frame is fixedly mounted on the inner wall of the top of the first mounting frame and the third mounting frame, and two symmetrically distributed conveying wheels are rotatably mounted in the two mounting frames, and the two wires slide between the two conveying wheels in the same group.

[0041] When the copper bar moves into the first mounting bracket 8 or the third mounting bracket 14, the third cylinder 16 drives the same group of clamps 7 to move, so that the two clamps 7 in the same group contact the opposite side of the copper bar, which can clamp and fix the copper bar, which is beneficial to maintaining the stability of the copper bar detection. After the copper bar is fixed, the scanner 9 is used to scan and detect the surface of the copper bar, and then the third telescopic rod 21 drives the connecting block 22 and the probe 23 to descend synchronously, so that the probe 23 contacts the surface of the copper bar.

[0042] The bottom ends of the second mounting brackets 10 extend into the bottom frame 1, and grooves 17 are provided on the inner walls on both sides of the second mounting brackets 10.

The cooperation of the slider and the sliding groove is conducive to maintaining the sliding stability of the first support block 19.

Then, the electric clamp 30 and the product are driven to rise synchronously by the first telescopic rod 12, and then the second support block 33 is driven to slide in the installation groove 34 by the second cylinder 13. The second support block 33 moves synchronously with the first telescopic rod 12 and the product, so that the product is moved out from above the conveyor belt 2, which can play a role in picking.

[0046] The implementation principle of the embodiment of the present utility model is as follows: when the equipment is in use, the staff places the copper bar on the conveyor belt 2, and the copper bar is transported by the conveyor belt 2. The side wall of the bottom frame 1 is set by the correction component. When the conveyor belt 2 transports the copper bar, the correction component can correct the copper bar to be located on the conveying position of the conveyor belt 2, which is convenient for subsequent accurate detection of the equipment. After the copper bar moves to the bottom of the first mounting bracket 8, the surface of the copper bar is scanned and detected by the scanner 9, and the copper bar is fixed by the clamping component. Then, the connecting block 22 and the probe 23 are driven to descend synchronously by the third telescopic rod 21, so that the probe 23 contacts the surface of the copper bar.
