Technical Field

[0001] This invention relates to the field of connector processing equipment, and in particular to a high-speed pin insertion machine for aviation plugs. Background Technology

[0002] Currently, aviation connectors are widely used in various industries such as communications, aviation, and power. A set of aviation connectors generally consists of male and female connectors, and data information is transmitted through the connection between the male and female connectors.

[0003] Traditionally, manual insertion of terminals into the core can only reach 500-600 units per hour, resulting in low production efficiency. Semi-automatic assembly equipment on the market can reach 1000-1200 units per hour. Although the speed has increased significantly, people have placed higher demands on the miniaturization and high density of terminals. Obviously, traditional pin insertion machines can no longer meet people's processing needs. Summary of the Invention

[0082] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0083] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0084] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0085] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0086] Please see Figures 1 to 16 As shown, this application provides a high-speed pin insertion machine for aviation plugs, including a frame 10, a feeding device, a transfer mechanism 20, a terminal feeding mechanism 30, and a cam-type pin insertion mechanism 40. The cam-type pin insertion mechanism 40 and the feeding device are both located on the frame 10, with the feeding device situated beside the cam-type pin insertion mechanism 40. The terminal feeding mechanism 30 is located beside the cam-type pin insertion mechanism 40 and conveys the terminal material strip 1.

[0087] The feeding device includes a core feeding mechanism 50, a track changing mechanism 60, a core insertion mechanism 70, a clamping mechanism 80, and a direction selection mechanism 90. The core feeding mechanism 50 feeds the core 2. One end of the core 2 has a recessed slot 3 on its outer wall for inserting a terminal. Optionally, there can be 4, 6, or 8 slots. After a terminal is inserted into one slot 3, the next slot is rotated to continue inserting a terminal, and so on, until all slots are checked. The other end of the core 2 has a recessed positioning notch 4 for aligning the core. The track changing mechanism 60 is located beside the output end of the core feeding mechanism 50. The core 2 enters the track changing mechanism 60 from the output end of the core feeding mechanism 50.

[0088] The core insertion mechanism 70 and the clamping mechanism 80 are located beside the track changing mechanism 60, and are positioned opposite each other. The track changing mechanism 60 moves the core 2 to the side of the output end of the core insertion mechanism 70, and the core insertion mechanism 70 inserts the core 2 into the clamping mechanism 80, thus allowing the core 2 to enter the clamping mechanism 80 from the track changing mechanism 60. The orientation selection mechanism 90 is located beside the clamping mechanism 80, and its detection end moves toward the core 2. The clamping mechanism 80 drives the core 2 to rotate, and the detection end of the orientation selection mechanism 90 engages with the positioning notch 4, so that the core 2 is positioned at a predetermined angle. When the core 2 subsequently reaches the position directly opposite the cam pin insertion mechanism 40, the slot 3 and the terminal insertion position are perfectly aligned, thus accurately inserting the terminal into the slot 3.

[0089] The clamping mechanism 80 is disposed on the transplanting mechanism 20. The transplanting mechanism 20 drives the clamping mechanism 80 to approach the cam pin mechanism 40, and the cam pin mechanism 40 inserts the terminal 5 into the slot 3.

[0090] The rubber core is automatically fed, transferred, and positioned at a predetermined angle using a rubber core feeding mechanism 50, a track changing mechanism 60, a rubber core insertion mechanism 70, a clamping mechanism 80, and a direction selection mechanism 90. Then, it is sent to the side of the cam pin insertion mechanism 40. The feeding mechanism 30 automatically feeds the terminal strip, and the cam pin insertion mechanism 40 clamps the terminals in the terminal strip and inserts them into the slot 3. The entire processing is fully automated, greatly improving production efficiency. The angle is selected by using the detection end of the direction selection mechanism 90 to engage with the positioning notch 4 of the rubber core 2. Its design is ingenious, its structure is simple, and its cost is low.

[0091] Optionally, the transplanting mechanism 20 is a linear module, which drives the clamping mechanism 80 to move back and forth in a straight line between the core insertion mechanism 70 and the cam pin insertion mechanism 40.

[0092] Optionally, the core insertion mechanism 70 is a cylinder, which is located directly opposite the clamp mechanism 80. The output shaft of the cylinder pushes the core into the clamp mechanism 80.

[0093] Optionally, the rubber core feeding mechanism 50 includes a vibratory feeder 51, the output end of which is connected to a linear feeder 52, and the output end of the linear feeder 52 is connected to a track changing mechanism 60. After the vibratory feeder 51 selects the direction of the rubber core, it is fed into the track changing mechanism 60 through the linear feeder 52.

[0094] The track-changing mechanism 60 includes a cylinder 61, a sliding plate 62, and a clamping arm 63; the cylinder 61 is mounted on the frame 10. The sliding plate 62 is connected to the output shaft of the cylinder 61, and the cylinder 61 drives the sliding plate 62 to move closer to or away from the core insertion mechanism 70. Optionally, for the sliding plate 62 to slide stably, the sliding plate 62 and the frame are connected by a sliding rail and a slider. The end of the sliding plate 62 near the core feeding mechanism 50 has a first arc-shaped notch 621. The clamping arm 63 is pivotally connected to the sliding plate 62. The clamping arm 63 includes a straight arm section 631 and an inclined arm section 632 integrally connected, and the pivot point is located at the intersection of the straight arm section 631 and the inclined arm section 632. The top surface of the end of the straight arm section 631 and the bottom surface of the sliding plate 62 are connected by a spring (not shown). Under the elastic force of the spring, the sliding plate 62 and the clamping arm 63 stably clamp the core. The inclined arm segment 632 extends toward the sliding plate 62, and the inclined arm segment 632 is recessed with a second arc-shaped notch 633 near the first arc-shaped notch 621. The second arc-shaped notch 633 and the first arc-shaped notch 621 form a first clamping groove. The first clamping groove is directly opposite the output end of the glue core feeding mechanism 50. Under the action of the spring, the first clamping groove can open and close. When the glue core insertion mechanism 70 inserts the glue core into the clamping mechanism 80, the first clamping groove is squeezed open, thereby ensuring that the glue core 2 is smoothly inserted into the clamping mechanism 80.

[0095] The clamping mechanism 80 includes: a mounting frame 81, a servo motor 82, a first cylinder 83, a clamping member 84, a sleeve 85, a spring 86, and a clamping clip 87. The mounting frame 81 is fixed to the output end of the transplanting mechanism 20; the servo motor 82 is mounted on the mounting frame 81. The clamping member 84 is sleeved on the output shaft of the servo motor 82, and the servo motor 82 drives the clamping member 84 to rotate. The clamping member 84 has an elastic clamping head 841 near the end of the inserting core mechanism 70. The elastic clamping head 841 has a second clamping groove 842 for clamping the core 2, and the outer wall of the elastic clamping head 841 has a first inclined surface 843. Optionally, the elastic clamping head 841 is composed of multiple spaced elastic thin blocks arranged in a circular pattern.

[0096] The sleeve 85 is fitted over the elastic clamp head 841. The inner wall of the sleeve 85 has a second inclined surface 851, which fits against the first inclined surface 843. At this time, the elastic clamp head 841 is subjected to inward squeezing force from the sleeve 85, causing the second clamping groove 842 to shrink, thereby clamping the rubber core 2. When the first inclined surface 843 separates from the second inclined surface 851 (i.e., when they are not completely fitted), the second clamping groove 842 opens under the action of elastic force. At this time, the rubber core 2 can be inserted into the second clamping groove 842 from the track changing mechanism. The spring 86 is fitted on the sleeve, with one end of the spring 86 abutting against the sleeve 85 and the other end abutting against the mounting bracket 81. The first cylinder 83 is mounted on the mounting bracket 81. One end of the sleeve clamp 87 is fixed to the output shaft of the first cylinder 83, and the other end of the sleeve clamp 87 is pivotally connected to the mounting bracket 81. The sleeve clamp 87 is fixedly connected to the sleeve 85 by screws. The first cylinder 83 drives the sleeve 87 to pull back, and the sleeve 87 drives the sleeve 85 to move, so that the first inclined surface 843 is separated from the second inclined surface 851. At this time, the second clamping groove 842 opens. After the rubber core 2 is inserted into the second clamping groove 842, the first cylinder 83 drives the sleeve 87 to return to its original position, and the sleeve 85 is reset under the action of the sleeve 87 and the spring 86. The second clamping groove 842 clamps the rubber core.

[0097] The orientation selection mechanism 90 includes a second cylinder 91, a core angle detection element 92, a sensing plate 93, and a sensor 94. The second cylinder 91 is mounted on the frame 10. The core angle detection element 92 is mounted on the output shaft of the second cylinder 91. The second cylinder 91 drives the core angle detection element 92 to rise or fall. The lower end of the core angle detection element 92 extends downward with a pointed head 921. The shape of the pointed head 921 matches the shape of the positioning notch 4. When the pointed head 921 engages with the positioning notch 4, the servo motor 82 stops rotating the core 2, so that the core 2 is positioned at a predetermined angle. The sensing plate 93 is located on the side of the core angle detection element 92 and moves with it. The sensor 94 is mounted on the frame 10 and located beside the sensing plate 93. The sensor 94 is inductively connected to the sensing plate 93.

[0098] After the rubber core 2 is inserted into the chuck mechanism 80, the second cylinder 91 drives the rubber core angle detection component 92 to press down. When the sensing plate 93 and the sensor 94 successfully sense each other, the pressing is completed. At this time, the servo motor 82 drives the rubber core 2 to rotate. When the positioning notch 4 rotates to the position of the pointed tip 921, the two are locked together, and the servo motor 82 no longer drives the rubber core 2 to rotate. At this time, the rubber core 2 is positioned at a predetermined angle, and then the rubber core 2 will be sent to the side of the cam pin insertion mechanism 40 at this angle. It should be noted that the force of the servo motor 82 driving the rubber core 2 to rotate is not large, and when the pointed tip 921 falls into the positioning notch 4, it will not damage the rubber core.

[0099] The cam pin insertion mechanism 40 includes a base 41, a drive motor 42 mounted on the base 41, a cam group, and a pin insertion assembly. The cam group consists of a first cam 44 and a second cam 45 mounted sequentially from bottom to top on a drive shaft 43. The drive shaft 43 is vertically mounted on the base 41, and the drive motor 42 is connected to the lower end of the drive shaft 43.

[0100] The pin assembly includes a pin rod 46, a mounting base 47, a first clamp 48, and a second clamp 49. The mounting base 47 has a first mounting portion 471 and a second mounting portion 472, which are symmetrically arranged on both sides of the pin rod 46. The first clamp 48 is movably mounted on the first mounting portion 471. The second clamp 49 is movably mounted on the second mounting portion 472. The pin rod 46 is drivenly connected to a second cam 45, which moves the pin rod 46 away from or towards the clamp mechanism 80. The mounting base 47 is drivenly connected to a first cam 44, which moves the first mounting portion 471 and the second mounting portion 472 toward or away from the clamp mechanism 80.

[0101] The first chuck 48 is connected to the first cam 44, and the second chuck 49 is connected to the second cam 45. The first chuck 48 and the second chuck 49 move toward each other or in opposite directions under the action of the first cam 44 and the second cam 45.

[0102] In one embodiment, the top surface of the first cam 44 is provided with a first cam track 441 and a second cam track 442, the second cam track 442 being located outside the first cam track 441; the mounting base 47 includes a connecting rod portion 473, a main body portion 474, a first mounting portion 471 and a second mounting portion 472, one end of the connecting rod portion 473 being mounted on the first cam track 441 via a first roller 410; one end of the main body portion 474 being connected to the other end of the connecting rod portion 473; the first mounting portion 471 and the second mounting portion 472 protruding from both sides of the other end of the main body portion 474 respectively.

[0103] The first chuck 48 is movably mounted on the first mounting part 471 via the first chuck seat 411. The first chuck seat 411 is connected to the second cam track 442 via the first connecting rod 412. The first chuck seat 411 and the first connecting rod 412 are connected via the second roller 413. The first connecting rod 412 and the second cam track 442 are connected via the third roller 414. The first connecting rod is pivotally connected to the base 41 at the middle position. The first cam 44 drives the first connecting rod 412 to swing at the pivot point.

[0104] In one embodiment, the bottom surface of the second cam 45 is provided with a third cam track 451 and a fourth cam track 452, the fourth cam track 452 being located outside the third cam track 451; the pin rod 46 is fixed to one end of the second connecting rod 415 and is directly opposite the clamping mechanism 80; the other end of the second connecting rod 415 is connected to the third cam track 451 via a fourth roller 416; the top surface of the main body 474 is provided with a clearance groove 475, through which the second connecting rod 415 passes;

[0105] The second chuck 49 is movably mounted on the second mounting part 472 via the second chuck seat 417. The second chuck seat 417 is connected to the fourth cam rail 452 via the third connecting rod 418. The second chuck seat 417 and the third connecting rod 418 are connected via the fifth roller 419. The third connecting rod 418 and the fourth cam rail 452 are connected via the sixth roller 420. The third connecting rod is pivotally connected to the base 41 at the middle position. The second cam 45 drives the third connecting rod 418 to swing at the pivot point.

[0106] When the core 2 is detected to be in the position directly opposite the pin rod 46, the drive motor 42 drives the first cam 44 and the second cam 45 to rotate. At time T1, the first chuck 48 and the second chuck 49 move towards each other under the action of the first cam 44 and the second cam 45 to clamp the terminals on the terminal strip, and the first chuck 48 and the second chuck 49 maintain the state of clamping the terminals. At time T2, the first cam 44 drives the mounting base 47 to move towards the core, and the mounting base 47 drives the terminals clamped on the first chuck 48 and the second chuck 49 to reach between the core 2 and the pin rod 46. At time T3, the second cam 45 drives the pin rod 46 to move towards the core 2, and the pin rod 46 inserts the terminals into the slots 3. After a terminal is inserted into one slot 3, the chuck mechanism drives the core to rotate a certain angle so that the other slot of the core is directly opposite the pin rod 46. The above processing steps are repeated to insert other terminals, and multiple slots are inserted into terminals in sequence.

[0107] Optionally, the terminal feeding mechanism 30 includes: a terminal feeding tray 31, a first sensing rod 32, a second sensing rod 33, a take-up tray 34, a motor 35, a driving ratchet 36, a driven ratchet 37, and a conveying track block 38; the terminal feeding tray 31 is mounted on the frame for feeding terminal strips. The first sensing rod 32 and the second sensing rod 33 are mounted on the frame and located beside the terminal feeding tray 31. When the first sensing rod 32 has no signal, the take-up tray 34 stops rotating; when there is a signal (low level), the terminal feeding tray 31 rotates, and the take-up tray 34 rotates simultaneously. Both the motor 35 and the conveyor track block 38 are mounted on the base 41. The terminal strip passes between the first and second clamps. The conveyor track block 38 has recessed strip grooves arranged vertically, and the terminal strip is conveyed along these grooves. The driving ratchet 36 is mounted on the output shaft of the motor 35, and the driven ratchet 37 is rotatably mounted on the base, with both arranged vertically in a straight line. The driving ratchet 36 and the driven ratchet 37 engage with the strip holes of the terminal strip, thereby driving the terminal strip. A terminal sensor is mounted on the base 41, located beside the terminal strip. When the terminal sensor detects a shortage of material in the terminal strip, the conveyed terminal strip is conveyed downwards by one more station to avoid empty insertion.

[0108] A finger positioning cylinder 100 is provided between the pin rod 46 and the clamping mechanism 80 for positioning the rubber core 2 before the terminal 5 is inserted into the slot 3.

[0109] The frame 10 is equipped with a terminal strip cutting mechanism 110, which is located below the cam pin insertion mechanism 40 and beside the terminal strip 1 conveying track. The terminal strip cutting mechanism 110 includes a cylinder and a cutter. The cylinder drives the cutter to cut and recycle the terminal strip after the terminal is removed.

[0110] There are two feeding devices, located on both sides of the cam pin insertion mechanism 40. The two feeding devices work alternately, thus working continuously and greatly improving production efficiency. The pin insertion rate can reach 1500-1600 pins per hour.

[0111] The chuck is equipped with an air blower 88, which contains an air passage 881. The mounting bracket 81 has an air inlet 811. One end of the air passage 881 connects to the air inlet 811, and the other end connects to the second clamping groove 842. The frame 10 is equipped with a feeding pipe 120, located between the core insertion mechanism and the chuck mechanism. After the pin insertion is completed, the chuck mechanism 80 moves to the feeding pipe 120 and releases its grip on the plug. At this time, air enters through the air passage 881, blowing the processed plug out and dropping it into the feeding pipe 120 for feeding. The core insertion mechanism inserts the next processed core into the chuck mechanism for further processing.

[0112] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
