Description

Technical Field

[0001] The present invention belongs to the field of intelligent processing technology, and in particular relates to an automatic straightening device for capacitor pins. Background Art

[0002] With the rapid development of modern science and technology, high-power capacitors are increasingly used in electronic devices, especially in high-end technology fields such as radar systems. High-power capacitors can provide a large amount of electrical energy in a short period of time, meeting the radar system's demand for instantaneous high power. Due to the complex production processes and extremely high appearance requirements of high-power capacitors, they are processed in bulk during each process. During electrical performance testing, the capacitor pins need to be straightened and ensure that the pins are free of appearance defects such as scratches, burrs, and missing plating. Currently, special tooling is used to manually straighten the capacitor pins one by one. Then, inspectors use visual inspection or tools such as microscopes to detect the capacitor's straightening effect and appearance defects. This has problems such as low detection efficiency, high labor intensity, and easy error. Chinese utility model patent application number CN201520945476.2 discloses a special tooling for axial component pin straightening. It straightens the component pins by driving a mechanical arm to vibrate, with the advantages of simple operation, safety, and low labor intensity. Chinese utility model patent application number CN202321469824.4 discloses a resistance wire shaping and cutting device that can shape and straighten each resistance wire pin on the leaked resistance wire braid. It is easy to operate and has high compatibility and safety.

A rectangular avoidance groove 2511 is provided in the middle, and two limiting edges 2512 are provided on the upper surface of the main body 251 along the long sides of the rectangular avoidance groove 2511; discharge notches 25121 are arranged in an array in the length direction of the limiting edges 2512, and the upper part of the discharge notch 25121 is a trumpet-shaped guide mouth 251211 and the lower part is a semicircular groove 251212. The trumpet-shaped guide mouth 251211 can facilitate the placement of capacitor products, and the semicircular groove 251212 can limit the position of the capacitor in the tray 25 for easy turnover and transportation.

[0052] Based on this, a typical working process of the present invention is:

[0053] When the present invention is implemented, Figure 1-19 As shown; first, start the equipment, then select the product model to be processed, manually stack the trays 25 filled with capacitor products 8 according to the set quantity and put them into the first warehouse body 210 of the capacitor silo 21, and then lift the tray stack through the first lifting cylinder 212. Then the first blocking cylinder 2113 of the tray dividing mechanism 211 drives the blocking plate 2114 to extend and insert it into the material dividing slot 2510 of the tray 25, blocking the upper tray of the penultimate tray in the tray stack, and the first lifting cylinder 212 is reset. The bottom tray 25 falls on the tray conveyor belt 22, and the tray 25 moves forward to be blocked by the second blocking cylinder 24. Stop, at this time the loading and transporting component 3 grabs the capacitor product 8 in the tray 25 and puts it into the straightening component 4 until all the products in the tray 25 are taken away, the second blocking cylinder 24 is reset, and the empty tray 25 is transported to the lower part of the second warehouse body 230 of the empty tray warehouse 23, and the second lifting cylinder 232 lifts the tray 25 to pass through the inclined surface of the guide bevel 23122 and then the second lifting cylinder 232 is reset, and the guide bevel 23122 is reset under the action of the first spring 23123 and the rotating pin 23124; the tray 25 falls on the back of the guide bevel 23122, and the product feeding and empty tray recovery are realized in this reciprocating cycle.

[0054] After the loading and transporting component 3 takes the capacitor product 8 from the material tray 25, it is placed in the limiting semicircular groove 45311 of the capacitor support plate 453 in the straightening component 4, and then the moving part of the vertical cylinder 43 moves downward to drive the two floating straightening components 442 of the floating straightening mechanism 44 to move downward. The straightening plate 4422 of the floating straightening component 442 contacts the pins of the capacitor product 8. At this time, the second spring 4424 is in a slightly compressed state, and the slider of the screw module 42 reciprocates the set number of times, driving the straightening plate 4422 to straighten the pins of the capacitor product 8. Under the friction force of the straightening plate 4422, the capacitor product 8 rotates in the limiting semicircular groove 45311 to achieve circumferential straightening of the pins of the capacitor product 8. Finally, the vertical cylinder 43 and the screw module 42 are reset to complete the straightening. Then the loading and transporting component 3 grabs the straightened capacitor product 8 and places it into the first discharge slot 5410 of the discharge rack 541 of the support frame 54 in the appearance inspection component 5. Finally, the loading and transporting component 3 puts the new capacitor product 8 into the straightening component 4 and repeats the cycle to realize the straightening process of the capacitor product 8.

[0055] The capacitor product 8 in the first discharge trough 5410 is lifted up by the "V"-shaped fork plate 538 through the single-rod lifting cylinder 533, and then the second screw module 531 moves forward one material level, and the single-rod lifting cylinder 533 drives the "V"-shaped fork plate 538 to reset, and the capacitor product 8 falls into the second discharge trough 5411; at the same time, the capacitor product 8 originally in the second discharge trough 5411 is placed in the third discharge trough 5412, and at this time, the pushing cylinder 553 is pushed out to drive the first rotating clamp 556 and the second rotating clamp 557 to extend forward, and the clamps of the first rotating clamp 556 and the second rotating clamp 557 respectively clamp one end of the capacitor product 8 in the second discharge trough 5411 and the third discharge trough 5412 and rotate them. The circumferential camera component 51 detects the appearance of the pins of the capacitor product 8 in the second discharge trough 5411 in the circumferential direction, and the end camera component 52 detects the appearance of the capacitor product 8 in the axial direction in the third discharge trough 5412 and uploads the photographed image to the host computer. The system performs defect analysis. After the inspection is completed, the unloading and conveying component 6 classifies and places the capacitor products in the third discharge trough 5412. If it is a qualified product, it is placed in the material tray 25 of the unloading component 7. If it is an unqualified product, it is placed in the unqualified product classification box 71 of the unloading component 7. At this point, all the processes of loading, straightening, appearance inspection and unloading of a product are completed. The equipment repeats the above process until the set number of products are processed.
