Description

Technical Field

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

[0002] The single-PIN terminal feeding mechanism is a core auxiliary equipment in the automated terminal production line that connects raw materials and the injection molding process. Its main function is to accurately and stably transport single-PIN terminals to the designated area of ​​the injection molding machine, and to check for problems such as terminal misalignment and missing terminals during the transport process, thus ensuring the continuous and efficient production of the injection molding machine.

[0003] However, existing single-PIN terminal feeding mechanisms mostly adjust the height of the vibratory feeder via a lead screw during feeding. The high-frequency vibrations generated by the vibratory feeder can easily cause gaps between the lead screw and nut pair, leading to lead screw rotation and unexpected height deviation of the vibratory feeder. This disrupts the coaxiality of the conveying channel and affects the stability of terminal feeding. Furthermore, the terminals continuously fed to the end of the terminal guide rail are tightly stacked, increasing the difficulty of the feeding assembly and reducing feeding accuracy. This can also cause terminal edge deformation and PIN bending due to pressure during feeding, directly affecting product quality. Simultaneously, after the feeding block completes feeding and resets upwards, the terminals awaiting reception at the end of the terminal guide rail are prone to falling or becoming disoriented due to loss of constraint. This results in delayed reception by the receiving fixture, affecting the alignment accuracy of subsequent PINs and terminal blocks, ultimately reducing product yield. Summary of the Invention

[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 3 , Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, the single-PIN terminal feeding mechanism of the present invention includes a workbench 1, a base plate 7 mounted on the workbench 1, an adjustment structure 2 mounted on the base plate 7, an adjustment plate 19 mounted on the adjustment structure 2, a conveying structure 3 mounted on the adjustment plate 19, a blocking structure 4 mounted on the conveying structure 3, and a support structure 5. The conveying structure 3 includes a vibratory feeder 301 mounted on the adjustment plate 19 and a linear feeder 302 mounted on the vibratory feeder 301. A terminal guide rail 303 is mounted on the linear feeder 302. The support structure 5 includes a support rod 501 slidably connected to the terminal guide rail 303 and a mounting plate 502 fixedly connected to the support rod 501. The mounting plate 502 is slidably connected to the terminal guide rail 303. A second spring 508 is fixedly connected between the mounting plate 502 and the terminal guide rail 303. A drive shaft 505 is rolledly engaged on the drive rod 503.

[0023] Specifically, such as Figure 3 , Figure 5 , Figure 6 and Figure 9 As shown, the workbench 1 is equipped with a terminal feeding module 8, a detection CCD 9, a product unloading module 10, and an injection molding machine 11. A receiving servo module 20 is mounted on the base plate 7. A fixed bracket 12 is mounted on the terminal feeding module 8, and a mold positioning CCD 13, a terminal separation cylinder 14, a first terminal picking module 15, and a second terminal picking module 16 are mounted on the fixed bracket 12. A first receiving fixture 17 and a second receiving fixture 18 are mounted on the receiving servo module 20. A drive rod 503 is fixedly connected to the mounting plate 502, and the drive rod 503 has an inclined surface 504. A needle-separating structure 6 is provided on the base plate 7. The needle-separating structure 6 includes a linear motor 601 mounted on the base plate 7 and a fixed seat 602 mounted on the slide of the linear motor 601. A needle-separating mechanism is mounted on the fixed seat 602. The needle block 603 is rotatably connected to the drive shaft 505 with a fixed rod 506. The fixed rod 506 is fixedly connected to the needle block 603. A terminal sensor 304 is installed on the terminal guide rail 303. A guide rod 507 is fixedly connected to the terminal guide rail 303. When the terminal sensor 304 detects that the terminal has been successfully transferred, the first drive member 405 drives the baffle 404 to retract and release the next terminal. When the linear motor 601 drives the needle block 603 to move upward and reset, the second spring 508 pulls the mounting plate 502 back, and the support rod 501 extends synchronously to reach the support position at the end of the rail in advance to prepare for the support of the next terminal to arrive. The mounting plate 502 is slidably connected to the guide rod 507, and two ball bearings 509 are rolledly connected to the support rod 501.

[0024] Specifically, such as Figure 5 and Figure 10 As shown, the blocking structure 4 includes a mounting base 401 mounted on the terminal guide rail 303 and a guide post 402 slidably connected to the mounting base 401. The first driving member 405 (preferably a hydraulic rod) drives the guide post 402 to extend the baffle 404 on the fixed plate 403, blocking the subsequent terminals from advancing, so that only a single terminal to be processed remains at the end of the rail, effectively avoiding the problem of material jamming and terminal damage caused by the tight contact of the terminals, and improving the accuracy of material distribution. The fixed plate 403 is fixedly connected to the guide post 402, and the baffle 404 is fixedly connected to the fixed plate 403. The first driving member 405 is mounted on the mounting base 401, and the fixed plate 403 is driven by the first driving member 405.

[0025] Specifically, such as Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the adjustment structure 2 includes an adjustment rod 201 fixedly connected to the base plate 7 and a lead screw 202 rotatably connected to the base plate 7. An adjustment plate 19 is slidably connected to the adjustment rod 201 and threadedly connected to the lead screw 202. The adjustment rod 201 has multiple graduated grooves 204. A limiting plate 203 is slidably connected to the adjustment plate 19, engaging with one of the graduated grooves 204. A spring plate 207 is fixedly connected to the adjustment plate 19. A connecting plate 205 is fixedly connected to the limiting plate 203. A connecting post 206 is rotatably connected to the connecting plate 205. A first spring 211 is fixedly connected between the connecting plate 205 and the spring plate 207. The connecting post 206 is rotated by the pull rod 209, causing the pull rod 209 to engage in the fixing groove 210. During adjustment, it is not necessary to continuously pull the pull rod 209, significantly improving operational flexibility. Next, the rotatable lead screw 202 drives the adjusting plate 19 to slide along the adjusting rod 201. Combined with the precise markings on the scale groove 204, the vibratory plate 301 is adjusted to the appropriate height, and then the pull rod 209 is released. The first spring 211 resets and pushes the limiting plate 203 into the corresponding scale groove 204, realizing the stable limiting of the adjusting plate 19. This adjustment can complete the height calibration without complicated tools. Moreover, through the engagement of the scale groove 204 and the limiting plate 203, the height deviation caused by high-frequency vibration during the operation of the vibratory plate 301 is effectively avoided, ensuring the coaxiality of the conveying channel composed of the vibratory plate 301, the linear feeder 302 and the terminal guide rail 303. A connecting sleeve 208 is fixedly connected to the spring plate 207, and a pull rod 209 is fixedly connected to the connecting column 206. The pull rod 209 is slidably connected to the connecting sleeve 208, and the connecting sleeve 208 is provided with a fixing groove 210.

[0026] In use, this invention first adjusts the equipment parameters on a single-PIN terminal automated production line according to the part number of the terminal to be processed. Pulling the pull rod 209 causes the connecting column 206 to drive the connecting plate 205 to compress the first spring 211, and the limiting plate 203 disengages from the scale groove 204 on the adjusting rod 201. Then, the pull rod 209 drives the connecting column 206 to rotate, causing the pull rod 209 to engage in the fixing groove 210. At this time, there is no need to continuously pull the pull rod 209 during the adjustment process, which greatly improves the operational flexibility. Next, the rotatable screw 202 drives the adjusting plate 19 to slide along the adjusting rod 201. Combined with the precise markings of the scale groove 204, the vibratory plate 301 is adjusted to the appropriate height, and then the pull rod 209 is released. The first spring 211 resets and pushes the limiting plate 203 into the corresponding scale groove 204, realizing the stable limiting of the adjusting plate 19. This adjustment can complete the height calibration without complicated tools, and through the scale groove 204... 4. The engagement with the limiting plate 203 effectively avoids height deviation caused by high-frequency vibration when the vibratory feeder 301 is working, ensuring the coaxiality of the conveying channel composed of the vibratory feeder 301, the linear feeder 302 and the terminal guide rail 303. Then, a batch of single-PIN terminals are poured into the vibratory feeder 301. After the vibratory feeder 301 is started, the terminals are orderly sorted by high-frequency vibration and smoothly conveyed to the terminal guide rail 303 by the linear feeder 302. The terminal sensor 304 on the terminal guide rail 303 detects the terminal position in real time. When a single terminal is detected to be about to reach the end of the rail, the first driving component 405 (preferably a hydraulic rod) drives the guide column 402 to extend the baffle 404 on the fixed plate 403 to block the subsequent terminals from advancing, so that only a single terminal to be processed remains at the end of the rail. This effectively avoids the problem of material jamming and terminal damage caused by the tight contact of the terminals and improves the accuracy of material distribution. When the terminal reaches the end of the terminal guide rail 303, the slide of the linear motor 601 drives the fixed seat 602 and the needle block 603 to move downwards. Simultaneously, it drives the drive shaft 505 on the fixed rod 506 to roll along the inclined surface 504 of the drive rod 503, pushing the mounting plate 502 to slide along the guide rod 507 and causing the second spring 508 to contract. The support rod 501 contracts accordingly, without affecting the downward pressure of the needle block 603. When the needle block 603 rises to a certain position, the support rod 501 extends and provides stable support to the terminal, preventing the terminal from falling or becoming disoriented due to loss of restraint after the needle block 603 rises. This improves the terminal feeding and receiving capabilities. To ensure stability, the needle block 603 continues to descend and separate the terminal to the first receiving fixture 17. During this process, the ball bearing 509 on the support rod 501 forms a rolling engagement with the needle block 603, reducing wear between the two and extending the service life of the component. When the terminal sensor 304 detects that the terminal has been successfully transferred, the first drive component 405 drives the baffle 404 to retract and release the next terminal. When the linear motor 601 drives the needle block 603 to move upward and reset, the second spring 508 pulls the mounting plate 502 back, and the support rod 501 extends synchronously to reach the support position at the end of the track in advance, preparing to support the next terminal that is about to arrive. The receiving servo module 20 drives the first receiving fixture 17 to move the terminal to the corresponding position of the receiving module. The detection CCD 9 captures images of the terminal arrangement and integrity and transmits them to an external processor to accurately check for defects such as misalignment and damage, preventing defective terminals from entering subsequent processes and effectively reducing the product defect rate. When the inspection results are qualified, the mold positioning CCD 13 captures the precise coordinates of the mold of the injection molding machine 11 in real time and feeds them back to the control system. The terminal separation cylinder 14 drives the first terminal picking module 15 or the second terminal picking module 16 to clamp the terminal and accurately transfer the terminal to the injection molding machine according to the positioning data. Inside the mold of injection molding machine 11, the design of two terminal picking modules working alternately perfectly matches the production rhythm of injection molding machine 11, greatly improving the feeding efficiency. After injection molding, the product unloading module 10 transports the molded product to the designated storage area. At the same time, the receiving servo module 20 synchronously drives the second receiving fixture 18 to move to the end of the terminal guide rail 303 to receive the next terminal, realizing the automated closed-loop operation of receiving, inspection, transfer and unloading. The whole process greatly reduces manual intervention. The modular structural design not only reduces equipment maintenance costs, but also fully ensures production stability and product quality through the collaborative work of various components.
