Description

Technical Field

[0001] This invention relates to the field of feeding mechanism technology, specifically a connecting terminal feeding mechanism. Background Technology

[0002] In the automated production of connector terminals, the existing continuous terminal feeding mechanism serves as an auxiliary device for conveying terminal raw materials to the injection molding area. Its core function is to guide and convey the terminal material strip to the designated workstation to complete the production in conjunction with the injection molding machine. Some mechanisms also have preliminary terminal misalignment detection and material shortage troubleshooting functions to ensure the stable operation of the injection molding machine.

[0003] However, during the reset of the pusher slider in the feeding mechanism, the inclined surface of the insertion rod cannot adapt to the vertical deviation of the PIN pin, and the built-in spring is prone to fatigue, resulting in sluggish retraction. In addition, the reset speed driven by the hydraulic rod fluctuates. Even though the end of the insertion rod has an inclined surface, it is still easy to make hard contact with the PIN pin and cause dragging, which ultimately leads to the displacement of the PIN pin and affects the subsequent conveying accuracy. At the same time, the paper tape winding process adopts a single rotation mode of motor-driven winding reel. As the diameter of the waste tape roll increases, the tensile stress gradually increases, which leads to the problem of loose winding. In addition, during the terminal cutting process, the impact load and shearing force generated by the cutter are transmitted to the PIN pin through the material tape, causing the PIN pin to shift and shake, affecting product quality.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 — Figure 6As shown, the terminal feeding mechanism of the present invention includes a worktable 1, a first continuous terminal 7, a second continuous terminal 8, a terminal feeding module 9, a receiving module 10, a product unloading module 11, an injection molding machine 12, a cutter 14, a terminal separating module 15, a feeding module 16, a waste terminal pressing cylinder 17, a waste terminal separating cylinder 18, and a CCD 19 mounted on the worktable 1, two fixing plates 13 mounted on the worktable 1, a pushing structure 2 mounted on the fixing plate 13, a limiting structure 4 mounted on the fixing plate 13, and a device mounted on the worktable 1. The belt take-up structure 5 and the pressure structure 6 installed on the belt take-up structure 5; the limiting structure 4 includes a fixing pin 401 slidably connected to the fixing plate 13 and a connecting plate 402 fixedly connected to the fixing pin 401. A guide rod 403 is fixedly connected to the fixing plate 13. A threaded ring 404 is threadedly connected to the guide rod 403. A third spring 405 abuts between the connecting plate 402 and the threaded ring 404. A drive plate 406 is fixedly connected to the connecting plate 402. The drive plate 406 is inclined. The drive plate 406 is used in conjunction with the pusher structure 2 and the drive structure 3.

[0023] Specifically, such as Figure 1 , Figure 4 , Figure 5 , Figure 7 — Figure 9As shown, the pushing structure 2 includes a guide rail 201 fixedly connected to the fixed plate 13 and a slider 202 slidably connected to the guide rail 201. A push block 203 is fixedly connected to the slider 202, and a push rod 204 is slidably connected to the push block 203. The push rod 204 has a wedge-shaped surface and a connecting ring 205 is fixedly connected to the push rod 204. The connecting ring 205 is slidably connected to the push block 203, and a first spring 206 is fixedly connected between the connecting ring 205 and the push block 203. After the material strips of the first continuous terminal 7 and the second continuous terminal 8 are initially guided by the terminal feeding module 9, they enter the receiving module 10 for temporary storage. The first driving component 301 (preferably a hydraulic rod) is activated, and its telescopic end pushes the slide plate 302 to move. The slide plate 302 synchronously drives the slide rod 303 to move. When the slide rod 303 moves in the slot 209, its end... The roller 304 rolls along the inclined drive plate 406, which in turn pushes the drive plate 406 to drive the connecting plate 402 to slide upward along the guide rod 403, so that the fixing pin 401 disengages from the material belt positioning hole, thus avoiding obstruction to the material belt conveying. At the same time, the slide rod 303 abuts against the slider 202, causing the slider 202 to slide along the guide rail 201. The cooperation between the guide rail 201 and the guide post 207 makes the movement of the slider 202 more stable, while the tension spring 208 between the slider 202 and the guide post 207 stores elastic potential energy for subsequent reset, effectively reducing the load on the first drive component 301. The slider 202 further drives the push block 203 and the push rod 204 to move. The push rod 204 directly pushes the material belt to be conveyed in the preset direction. The guide post 207 is fixedly connected to the guide rail 201, and the tension spring 208 is fixedly connected between the slider 202 and the guide post 207.

[0024] Specifically, such as Figure 4 , Figure 5 , Figure 8 , Figure 10 and Figure 11As shown, the drive structure 3 includes a first drive member 301 mounted on the fixed plate 13 and a slide plate 302 mounted on the drive end of the first drive member 301. A slide rod 303 is slidably connected to the slide plate 302. A slot 209 is provided between the slide rod 303 and the slider 202. A roller 304 is rotatably connected to the slide rod 303. The roller 304 rolls with the drive plate 406. As the slide rod 303 moves continuously with the slide plate 302, the drive shaft 306 of the connecting block 305 on the slide rod 303 gradually enters the parallelogram drive of the drive block 307. When the material belt is pushed to a preset position near the fixing pin 401, the drive shaft 306 rolls with the inclined surface of the drive groove 308, causing the slide bar 303 to slide upward on the slide plate 302 until the drive shaft 306 is engaged in the drop groove 309. During this process, the second spring 312 between the fixing ring 311 on the drive shaft 306 and the connecting block 305 provides a continuous preload force to ensure that the drive shaft 306 always fits against the inner wall of the drive groove 308, ensuring the accuracy of the action. When the material belt is fully pushed into place, the drive shaft 306 rises to... No longer in contact with the drive plate 406, the connecting plate 402, under the elastic action of the third spring 405, drives the fixing pin 401 downward to insert into the material strip hole to achieve locking. When the first drive component 301 resets, since the roller 304 disengages from the drive plate 406, the fixing pin 401 remains engaged with the material strip positioning hole, preventing material strip displacement during cutting and avoiding the slider 202 from resetting and causing the material strip to move, effectively ensuring terminal conveying accuracy and reducing product defect rate. When the telescopic end of the first drive component 301 retracts, the drive shaft 306... In conjunction with the other inclined surface and ramp 310 of the drive block 307, after moving downwards, it enters the straight groove through the drop groove 309 and continues to drive the drive plate 406 to operate, ensuring the stability of continuous operation of the equipment and improving production efficiency. At the same time, during the reset, due to the wedge-shaped surface of the push rod 204, the first spring 206 will deform through the connecting ring 205, which will not affect the reset of the push rod 204. A connecting block 305 is fixedly connected to the slide rod 303, and a drive shaft 306 is rotatably connected to the connecting block 305. A drive block 307 is installed on the fixed plate 13. The drive block 307 is provided with a drive groove 308, which is arranged in a parallelogram shape. Two drop grooves 309 are provided inside the drive block 307. Two ramps 310 are provided on the drive block 307. A fixing ring 311 is fixedly connected to the drive shaft 306. A second spring 312 is fixedly connected between the fixing ring 311 and the connecting block 305.

[0025] Specifically, such as Figure 1 and Figure 3As shown, the take-up structure 5 includes two mounting brackets 501 fixedly connected to the workbench 1 and a take-up roller 502 rotatably connected to the mounting brackets 501. A connecting disc 505 and a positioning rod 506 are fixedly connected to the take-up roller 502. A reducer 503 is mounted on the mounting brackets 501. The take-up roller 502 is mounted on the output shaft of the reducer 503. A second driving component 504 is mounted on the reducer 503. The pressure structure 6 includes a first synchronous pulley 601 mounted on the take-up roller 502 and a mounting shaft 602 rotatably connected to the mounting frame 501. A second synchronous pulley 603 is mounted on the mounting shaft 602. The first synchronous pulley 601 and the second synchronous pulley 603 are driven by a synchronous belt. A rotating shaft 605 is rotatably connected to the mounting frame 501. When the second drive component 504 (preferably a motor) is started, the power is transmitted to the take-up roller 502 after being reduced by the reducer 503. The reducer 503 converts the high-speed rotation into a stable low speed to prevent the waste tape from being torn due to excessive winding. The connecting disc 505 on the take-up roller 502 provides axial positioning for the waste tape to prevent offset during winding and subsequent stacking skewing. The positioning rod 506 facilitates quick installation of the take-up reel. At the same time, the take-up roller 502 drives the first synchronous pulley 601 to rotate, and drives the second synchronous pulley 603 to rotate synchronously with the mounting shaft 602 through the synchronous belt. The cam 604 on the mounting shaft 602 rotates accordingly. It rolls in conjunction with the lower pressure rod 607. When the protruding end of the cam 604 abuts against the lower pressure rod 607, it pushes the lower pressure rod 607 to rotate around the rotating shaft 605, causing the counterweight shaft 608 on the lower pressure rod 607 to press the waste strip. After the cam 604 rotates past the protruding end, the torsion spring 606 pulls the lower pressure rod 607 to return to its original position, and the counterweight shaft 608 remains in a light pressure state. This dynamic pressing can compact the loose part of the waste strip, increasing the waste collection capacity of the take-up roller 502, while the guide roller 609 guides... The waste belt smoothly enters the take-up roller 502, avoiding wrinkles. The counterweight shaft 608 rotates with the cam 604 to achieve a cycle of light pressure and tight pressure. This ensures the tightness of the waste belt during take-up and prevents damage caused by excessive compression, improving the regularity and stability of the waste belt take-up. No additional power source is required. Take-up and pressure are synchronized through linkage. A pressure rod 607 is fixedly connected to the rotating shaft 605. The counterweight shaft 608 is rotatably connected to the pressure rod 607. A guide roller 609 is rotatably connected to the mounting frame 501. A cam 604 is fixedly connected to the mounting shaft 602. The cam 604 and the pressure rod 607 roll together. A torsion spring 606 is fixedly connected between the rotating shaft 605 and the mounting frame 501.

[0026] In use, the material strips of the first continuous terminal 7 and the second continuous terminal 8 are initially guided by the terminal feeding module 9 and then temporarily stored in the receiving module 10. The first driving component 301 (preferably a hydraulic rod) is activated, and its telescopic end pushes the sliding plate 302 to move. The sliding plate 302 synchronously drives the sliding rod 303 to move. When the sliding rod 303 moves in the slot 209, the roller 304 at its end rolls along the inclined driving plate 406, thereby pushing the driving plate 406 to drive the connecting plate 402 to slide upwards along the guide rod 403, thus fixing... Pin 401 disengages from the material belt positioning hole to avoid obstructing the material belt conveying. At the same time, slide bar 303 abuts against slider 202, causing slider 202 to slide along guide rail 201. The cooperation between guide rail 201 and guide post 207 makes slider 202 move more smoothly. The tension spring 208 between slider 202 and guide post 207 stores elastic potential energy for subsequent reset, effectively reducing the load on the first drive component 301. Slider 202 further drives push block 203 and push rod 204 to move. Push rod 204 directly pushes the material belt to be conveyed in the preset direction. As the slide bar 303 continues to move with the slide plate 302, the drive shaft 306 of the connecting block 305 on the slide bar 303 gradually enters the parallelogram drive groove 308 of the drive block 307. When the material strip is pushed to a preset position close to the fixing pin 401, the drive shaft 306 rolls with the inclined surface of the drive groove 308, causing the slide bar 303 to slide upward on the slide plate 302 until the drive shaft 306 is engaged in the drop groove 309. During this process, the second spring 312 between the fixing ring 311 on the drive shaft 306 and the connecting block 305 provides a continuous preload force to ensure that the drive shaft 306 always fits against the inner wall of the drive groove 308, ensuring the accuracy of the action. When the material strip is fully pushed into place, the drive shaft 306 rises until it no longer contacts the drive plate 406, and the connecting plate 402 is driven by the elastic action of the third spring 405. The fixed pin 401 moves downward and inserts into the material strip hole to achieve locking. When the first drive component 301 resets, the fixed pin 401 remains engaged with the material strip positioning hole because the roller 304 disengages from the drive plate 406. This prevents the material strip from shifting during cutting and avoids the slider 202 from moving the material strip during reset, effectively ensuring the terminal conveying accuracy and reducing the product defect rate. When the telescopic end of the first drive component 301 retracts, the drive shaft 306 cooperates with the other inclined surface and ramp 310 of the drive block 307, moves downward and enters the straight groove through the drop groove 309, continuing to drive the drive plate 406 to operate, ensuring the stability of continuous operation of the equipment and improving production efficiency. At the same time, during reset, the wedge-shaped surface of the push rod 204 will deform the first spring 206 through the connecting ring 205, which will not affect the reset of the push rod 204. Once the material strip reaches the designated processing position, the cutter 14 starts to precisely cut the terminal material strip, separating the terminal units to be injected. The terminal sorting module 15 then operates to sort and directionally convey the cut terminal units, ensuring that the terminals are accurately fed into the mold cavity of the injection molding machine 12. After the injection molding machine 12 completes the injection molding and overmolding of the terminals, the molded connecting terminal products are automatically unloaded by the product unloading module 11 and transported to the designated storage area via a conveyor belt or mechanical grippers. The waste terminals generated after cutting are disposed of in the waste end. The pressing cylinder 17 pushes the pressing block to press and position it, preventing the waste terminal from tilting and shifting. Then the waste terminal separation cylinder 18 is activated to completely separate the waste terminal from the main material strip, which facilitates the subsequent winding of the waste strip by the winding structure 5. At the same time, the CCD 19 (charge-coupled device vision inspection component) performs real-time visual inspection on each process of terminal cutting, injection molding and separation, and identifies defects such as terminal size deviation, insufficient injection molding glue, and incomplete waste separation. Once an abnormality is detected, the equipment will be stopped and alarmed, which effectively improves the product yield. When recycling the waste tape generated after terminal cutting, the second drive unit 504 (preferably a motor) is activated. The power is reduced by the reducer 503 and then transmitted to the take-up roller 502. The reducer 503 converts the high-speed rotation into a stable low speed to prevent the waste tape from being torn due to excessive winding. The connecting disc 505 on the take-up roller 502 provides axial positioning for the waste tape to prevent offset during winding and subsequent stacking skewing. The positioning rod 506 facilitates quick installation of the take-up reel. At the same time, the take-up roller 502 drives the first synchronous pulley 601 to rotate, which in turn drives the second synchronous pulley 603 to rotate synchronously with the mounting shaft 602 via the synchronous belt. The cam 604 on the mounting shaft 602 rotates accordingly and rolls in cooperation with the pressure rod 607. When the protruding end of the cam 604 abuts against the pressure rod 607... When the cam 604 rotates past the protruding end, the pressure rod 607 is pushed to rotate around the shaft 605, causing the counterweight shaft 608 on the pressure rod 607 to press the waste strip. After the cam 604 rotates past the protruding end, the torsion spring 606 pulls the pressure rod 607 to reset, and the counterweight shaft 608 remains in a light pressure state. This dynamic pressure can compact the loose part of the waste strip, increase the amount of waste collected by the take-up roller 502, and the guide roller 609 guides the waste strip smoothly into the take-up roller 502 to avoid wrinkles. The counterweight shaft 608 rotates with the cam 604 to achieve a cycle of light pressure and tight pressure, which not only ensures the tightness of the waste strip take-up, but also prevents excessive compression from damaging the strip, improves the regularity and stability of the waste strip take-up, and does not require an additional power source. The take-up and pressure are synchronized through linkage.
