Description

Technical Field

[0001] This application relates to the field of high-density connector testing, and in particular to an automatic connector testing device. Background Technology

[0002] High-density connectors are electronic connectors designed to provide a large number of signal transmissions within a limited space. They are commonly used in electronic devices, especially in applications requiring large amounts of data and signal transmission, such as computers, communication equipment, data centers, and network equipment. In the assembly and production process of some small high-density connectors, the auxiliary connection material strips of the product are usually bent, cut, and stamped. As the processing goes on, some metal shavings will remain on the assembled connectors. However, in traditional technology, the detection of metal debris on connectors mainly involves workers using imaging equipment to capture images of the product, magnify the images, and then conduct visual inspections. In the case of batch connector inspection, manual operation is relatively time-consuming and inefficient. Summary of the Invention

[0011] By adopting the above technical solution, the L-shaped chute and square tube can be used to form an effective stacking of non-detection connectors, which greatly reduces the stacking time of square tubes and makes the overall operation more continuous.

[0012] Optionally, the receiving assembly includes: The receiving rack is fixedly connected to one end of the top of the support platform near another support plate.

[0021] By adopting the above technical solution, after the vacuum suction cup picks up the square tube at the loading tray, the slope of the loading tray allows the next square tube to reach the position to be picked up and wait for feeding.

[0041] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0042] This application discloses an automatic connector testing device. (Refer to...) Figure 1 and Figure 2 An automatic connector testing device includes: A support platform 1 is provided, and a vertical plate 2 is fixedly connected to the middle of the top of the support platform 1. An optical inspection component 3 is provided at the top of the vertical plate 2. The optical inspection component 3 is used to perform visual inspection of the connector. Two support frames 4 are fixedly connected to the two ends of the top of the support platform 1. Support plates 5 are fixedly connected to the top of each of the two support frames 4. Stacking components 6 are provided on the top of each of the two support plates 5. One stacking component 6 is used to stack square tubes 70 with connectors, and the other stacking component 6 is used to stack empty square tubes 70.

[0043] The feeding assembly 7 is mounted on top of one of the stacking assemblies 6 and is used to supply the stacking assembly 6 with a square tube 70 with a connector.

[0044] The receiving assembly 8 is assembled on one side of another stacking assembly 6 and is used to collect the finished product connector with the square tube 70 at the other stacking assembly 6.

[0045] The carrier component 9 is assembled between the two stacking components 6 and is used to pass the connector to the optical inspection component 3.

[0046] Defective product collection assembly 10 is assembled on the top of the support platform 1 and is used to collect defective connectors.

[0047] In this embodiment, the optical detection component 3 includes a light source for emitting light signals; a coupler for effectively coupling the light signals emitted by the light source into a connector; a detector for detecting light signals returning from the other end of the connector; a lens system for focusing the light signals, improving coupling efficiency and detection sensitivity; and a circuit board including an amplifier circuit, a signal processing circuit, and an interface circuit for amplifying the detected signals and performing necessary processing.

[0048] The principle is as follows: The light signal emitted by the light source enters the connector through the coupler. The light signal is transmitted in the connector. If the connector is good, most of the light signal will reach the other end through the connector. At the other end of the connector, some light signal may be reflected back. This reflected light can be detected by the detector. The detector converts the light signal into an electrical signal. The intensity of the electrical signal can reflect the intensity of the light signal. If there are defects in the connector, such as dust, oil, or uneven fiber end faces, it will cause the reflection of the light signal to increase or decrease. These changes can be detected by the detector. The amplification circuit amplifies the weak electrical signal output by the detector. The signal processing circuit can perform various functions, such as filtering, signal conversion, data acquisition and processing. The processed signal can be output to a display device or communicate with other systems through the interface circuit, thereby providing real-time feedback on the connection status. In summary, the optical detection component 3 is a mature existing technology and will not be described in detail here.

[0049] Reference Figure 3 and Figure 4 The stacking assembly 6 includes: two uprights 11, which are fixedly connected to the two ends of the top of the support plate 5, and stacking racks 12 are fixedly connected to the sides of the two uprights 11 that are close to each other. Each stacking rack 12 has an L-shaped groove 13 in the middle for accommodating the square tube 70. Two limiting assemblies 14 are respectively assembled at one end of the bottom of the two stacking racks 12 to limit the square tube 70. A material rack box 15 is fixedly connected to the top of one of the support plates 5 to receive the square tube 70 after the connector is discharged.

[0050] Linear guide rail A16 is fixedly connected to the top of support plate 5. A displacement push plate 17 is horizontally slidably connected to the top of linear guide rail A16. Both ends of the top of displacement push plate 17 are fixedly connected to receiving seats 18. Cylinder A19 is fixedly connected to the bottom of support plate 5. A push plate 20 is fixedly connected to the bottom of displacement push plate 17, and the output end of cylinder A19 is also fixedly connected to push plate 20. Cylinder B21 is vertically fixedly connected to the bottom of support plate 5. A storage groove is provided at one end of the top of support plate 5. An adjusting plate is fixedly connected inside the storage groove, and the output end of cylinder B21 is fixedly connected to the storage groove. Reference Figure 4 A clearance groove is provided in the middle of the top of the support plate 5, and the push plate 20 is located inside the clearance groove. The clearance groove can prevent the support plate 5 from affecting the displacement of the push plate 20. Both ends of the bottom of the displacement push plate 17 are fixedly connected to limit sliders, and the displacement push plate 17 is connected to the linear guide rail A16 through the limit sliders. The limit sliders enable the displacement push plate 17 to form an effective connection with the linear guide rail A16 and ensure the smoothness of the displacement push plate 17 sliding along the linear guide rail A16. In this embodiment, the receiving seat 18 is Z-shaped, and the height difference between the two ends of the top of the receiving seat 18 is adapted to the height of a single square tube 70. Through the structural characteristics of the receiving seat 18, the lower end of the receiving seat 18 can accommodate a single square tube 70, and when the receiving seat 18 pushes the square tube 70, the higher end of the receiving seat 18 can block the other square tubes 70, preventing the other square tubes 70 from sliding uncontrollably.

[0051] Reference Figure 5The limiting component 14 includes a mounting ear 23, which is fixedly connected to one end of the bottom of the stacking frame 12. A cylinder C24 is fixedly connected to one side of the mounting ear 23. The output end of the cylinder C24 is fixedly connected to a limiting seat 25. A cavity 26 is opened inside the limiting seat 25, and a vibration motor 27 is fixedly connected inside the cavity 26. The limiting seat 25 is U-shaped. Through the structural characteristics of the limiting seat 25, when the limiting seat 25 moves downward, the two ends of the limiting seat 25 can simultaneously limit the two ends of the square tube 70, ensuring the application effect of the limiting seat 25.

[0052] The vibration motor 27 includes: a coil: made of wire, which generates a magnetic field when an electric current flows through it; a magnet: the magnet is opposite the coil, and when the coil is energized, the interaction force between the magnet and the coil causes the coil to move; a spring: connected between the coil and the magnet, used to return the coil to its original position and provide elastic force during vibration; and a metal block: connected to the spring, whose movement generates vibration. The vibration motor 27 is mature prior art and will not be described in detail here.

[0053] Reference Figures 6-8 The feeding assembly 7 includes a feeding rack 28, which is fixedly connected between the top ends of two uprights 11. Linear guide rails B29 are fixedly connected to the inner walls of both ends of the feeding rack 28. Linear sliders 30 are slidably connected to the outer sides of both linear guide rails B29. A displacement rod 31 is vertically slidably connected to the end of each linear slider 30 away from the linear guide rail B29. A support plate 32 is fixedly connected between the bottoms of the two displacement rods 31. Multiple vacuum suction cups 33 for picking up the square tube 70 are fixedly connected to the support plate 32. Two central shafts 34 are rotatably connected to the top ends of the feeding rack 28. An eccentric plate A35 is fixedly connected to the end of each central shaft 34 that is close to each other. An assembly rod 36 is fixedly connected to the end of the eccentric plate A35 away from the central shaft 34, and the top ends of the two displacement rods 31 are rotatably connected to the outer sides of the two assembly rods 36. A transmission box 37 is fixedly connected to one end of the loading rack 28. A transmission motor 38 is fixedly connected to one side of the transmission box 37. A transmission spur gear 39 is fixedly connected to the output end of the transmission motor 38. A reduction spur gear 40 is fixedly connected to one end of one of the central shafts 34 located inside the transmission box 37, and the reduction spur gear 40 meshes with the transmission spur gear 39.

[0054] Two stabilizing frames 41 are fixedly connected to the two ends of the top of the loading rack 28, and a linkage shaft 42 is rotatably connected between the two stabilizing frames 41. Eccentric plates B43 are fixedly connected to both ends of the linkage shaft 42, and the ends of the two eccentric plates B43 away from the linkage shaft 42 are fixedly connected to two assembly rods 36 respectively. A loading tray 44 has multiple insertion rods A45 fixedly connected to the bottom of one end. The bottom inner side of the loading rack 28 has insertion holes A46 corresponding to each insertion rod A45, and the insertion rods A45 are inserted into the insertion holes A46. Reference Figure 7 The diameter of the transmission spur gear 39 is smaller than the diameter of the reduction spur gear 40. By changing the diameters of the transmission spur gear 39 and the reduction spur gear 40, the rotational speed of the central shaft 34 can be effectively controlled. Reference Figure 6 In this embodiment, the end of the loading tray 44 away from the insertion rod A45 is bent upwards, and baffles are fixedly connected to both ends of the top of the loading tray 44. Due to the structural characteristics of the loading tray 44, after the vacuum suction cup 33 picks up the square tube 70 at the loading tray 44, the slope of the loading tray 44 allows the next square tube 70 to reach the position to be picked up, ready for loading. The baffles prevent the two ends of the square tube 70 from detaching from the loading tray 44. Reference Figure 6 A positioning magnetic plate is fixedly connected to the bottom of the socket A46. The insertion rod A45 is made of metal and is also magnetically connected to the positioning magnetic plate. By using the positioning magnetic plate, after the insertion rod A45 is inserted into the socket A46, the positioning magnetic plate will hold the insertion rod A45 in place, thus preventing uncontrollable movement of the insertion rod A45 inside the socket A46 and ensuring the stability of the loading tray 44 after it is properly positioned.

[0055] Reference Figure 9 The receiving assembly 8 includes a receiving rack 47, which is fixedly connected to one end of the top of the support platform 1 near another support plate 5. Linear guide rails C48 are fixedly connected to both ends of one side of the receiving rack 47. A lifting frame 49 is slidably connected between the two linear guide rails C48. Insert rods B50 are fixedly connected to both ends of the lifting frame 49. A rodless cylinder 51 is fixedly connected to the middle of one side of the receiving rack 47, and the output end of the rodless cylinder 51 is fixedly connected to the lifting frame 49. A positioning frame 52 has an assembly plate 53 fixedly connected to its back. Insert holes B54 are fixedly connected to both ends of the assembly plate 53. The assembly plate 53 is sleeved on the outside of the insert rods B50 through the insert holes B54. Multiple collection plates 55 are fixedly connected to the front of the positioning frame 52. Each collection plate 55 has a limit groove 56 at its end away from the positioning frame 52.

[0056] Reference Figure 11The supporting component 9 includes a transfer plate 57, which is fixedly connected to the bottom end of one side of the upright plate 2. The transfer plate 57 has a finished product transfer channel 58 and a defective product transfer channel 59 inside. Both ends of the finished product transfer channel 58 face the two supporting plates 5, and one end of the defective product transfer channel 59 faces the defective product collection component 10. A pusher plate 60 is slidably connected to the other end inside the defective product transfer channel 59. A cylinder D61 is fixedly connected to the other side of the upright plate 2, and the output end of the cylinder D61 is fixedly connected to the pusher plate 60. In this embodiment, the top of the transfer plate 57 is made of a transparent material. Due to the material properties of the top of the transfer plate 57, it will not obstruct the optical detection component 3, thereby ensuring the detection effect of the optical detection component 3.

[0057] Reference Figure 12 and Figure 13 The defective product collection assembly 10 includes a collection rack A62 and a collection rack B63, both of which are fixedly connected to the top of the support platform 1. The top of each collection rack A62 and collection rack B63 has a collection groove 64 for accommodating the square tube 70. A receiving plate 65 is fixedly connected to the top of one side of the collection rack A62. A positioning block 67 is fixedly connected to one end of the top of the collection rack A62, and a cylinder E68 is fixedly connected to one side of the positioning block 67. A guide plate 69 is fixedly connected to the output end of the cylinder E68.

[0058] Reference Figure 13 A baffle 66 is bolted to the top of the receiving plate 65. The baffle 66 can block the connectors transmitted through the defective product transmission channel 59, preventing the connectors from detaching from the receiving plate 65. A linear guide rod is slidably connected to the top of the positioning block 67, and the end of the linear guide rod near the guide plate 69 is also fixedly connected to the guide plate 69.

[0059] The implementation principle of the automatic connector testing device of this application is as follows: After the connectors are assembled, they are fed one by one into the testing device using an air pump. Figure 14 The square tube 70 shown (each square tube 70 can store multiple connectors) is filled until the square tube 70 is full. Then, the worker places the square tube 70 on the loading tray 44 to wait for the material to be loaded, and places a square tube 70 in the placement slot 64.

[0060] The subsequent personnel move the loading tray 44 with the square tube 70 to the inside of the loading rack 28, and align the insertion rod A45 with the insertion hole A46. Then, the loading tray 44 is lowered to move the insertion rod A45 into the insertion hole A46, thus positioning the loading tray 44. Then, the vacuum suction cup 33 picks up the square tube 70 closest to the loading rack 28, and the drive motor 38 is started to cause the drive spur gear 39 to move the reduction spur gear 40, thereby driving the assembly rod 36 to rotate through the central shaft 34 and the eccentric plate A35.

[0061] When the assembly rod 36 rotates with the central shaft rod 34, it pulls the displacement rod 31 vertically under the limit of the linear slider 30. At the same time, the displacement rod 31 drives the linear slider 30 to slide along the linear guide rail B29 until the bottom end of the bearing plate 32 corresponds to the L-shaped groove 13. Then, the vacuum suction cup 33 stops sucking up the square tube 70, and under the action of gravity, the square tube 70 can fall into the L-shaped groove 13 and be received by the receiving seat 18. This process can be repeated to achieve convenient feeding of the square tube 70. After the square tube 70 is fed into the outer wall of the loading tray 44, the next loading tray 44 can be replaced.

[0062] Empty square tubes 70 are stacked inside another L-shaped chute 13 and received by another receiving seat 18. Then, cylinder A19 is activated to push push plate 20. With the connection between push plate 20 and displacement push plate 17, displacement push plate 17 can drive receiving seat 18 to slide along linear guide rail A16, so as to push a square tube 70 received by receiving seat 18 along L-shaped chute 13 towards limiting seat 25. Then, cylinder C24 is activated to push limiting seat 25 vertically. With the structural characteristics of limiting seat 25, the square tube 70 pushed by receiving seat 18 can be limited at limiting seat 25.

[0063] Then, cylinder B21 is activated to push the adjusting push plate 22 upward. As the adjusting push plate 22 contacts the square tube 70, one end of the square tube 70 can tilt. Then, vibration motor 27 is activated. The vibration generated by vibration motor 27 can be transmitted to square tube 70 through limit seat 25, causing the connector inside square tube 70 to be pushed to the finished product transmission channel 58. When the connector reaches the optical detection component 3, the connector is visually inspected by the optical detection component 3. When the optical detection component 3 observes that there are no metal shavings on the surface of the connector, the connector that has been inspected continues to move along the finished product transmission channel 58 as the next connector is pushed, until the connector reaches the empty square tube 70, so that the inspected connector can be received by the square tube 70.

[0064] When the empty square tube 70 is full, the cylinder A19 is activated to push the full square tube 70 toward the collection plate 55 until the square tube 70 reaches the inside of the limiting slide 56 for storage. When a single limiting slide 56 is full, the rodless cylinder 51 is activated to drive the lifting frame 49 to adjust along the linear guide rail C48 so that the height of the next collection plate 55 is adapted to the pushing height of the receiving seat 18. When multiple limiting slides 56 are full, the positioning frame 52 is lifted to disengage the eccentric plate B43 from the insertion rod B50, and other positioning frames 52 can be replaced.

[0065] When the optical inspection component 3 observes obvious metal shavings on the connector surface, the starting cylinder D61 pushes the pusher 60 to move along the defective product transfer channel 59 to push the defective product toward the receiving plate 65. Then, the starting cylinder E68 moves the defective product transfer channel 59 closer to the placement rack A62 to pull the connector at the receiving plate 65 toward the square tube 70 at the placement slot 64.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
