Description

Technical Field

[0001] This application relates to the field of terminal block processing, and in particular to a terminal workpiece feeding device. Background Technology

[0002] During the processing of terminal blocks, workpieces such as connecting pieces, arc extinguishing components, and bimetallic strips need to be installed in one of the terminal housings of the terminal block using mechanical grippers. Finally, the workpieces are fixed to the terminal housing by clamping bolts with mechanical grippers.

[0003] Chinese patent [CN222338758U] discloses a mechanism for installing parallel connectors for voltage terminals, comprising a mounting base, a rotating disk, a fixed base, mechanical grippers, a telescopic member, and a rotating rod. The rotating disk is rotatably connected to the mounting base around its own axis, with the axis of rotation of the rotating disk being horizontal. The fixed base is fixedly connected to the rotating disk. The mechanical grippers are fixedly connected to one end of the fixed base. The telescopic member is rotatably connected to the other end of the fixed base around its own axis, with the axis of rotation of the telescopic member perpendicular to the axis of rotation of the rotating disk. One end of the rotating rod is fixedly connected to the end of the telescopic member opposite to the mechanical grippers. The mechanical grippers hold the bolt portion of the parallel connector in the correct position. The rotation of the rotating disk drives the fixed base to rotate, so that the rotating rod is aligned with the bolt. The telescopic member extends and retracts, causing the rotating rod to embed into the slot on the upper part of the bolt. The rotation of the telescopic member drives the rotating rod to rotate, thereby tightening the bolt portion of the parallel connector onto the terminal block, facilitating fixation and improving production efficiency.

[0004] However, the above solution presents two problems in practical use. First, one terminal in the terminal block requires two steps: installing and tightening bolts, which increases the standby time of the other terminal to be processed. Second, because the mechanical grippers are fixed to the rotating disk, it is difficult to disassemble and replace them as a whole. Therefore, to install the connecting piece, arc extinguishing component, and bimetallic strip, additional facilities need to be added to the side of the production line, resulting in an increase in the length of the production line. Summary of the Invention

[0005] To facilitate the disassembly and replacement of mechanical grippers, this solution provides a terminal workpiece feeding device.

[0006] A terminal workpiece feeding device includes a mounting platform, a position adjustment mechanism mounted on the mounting platform, and a material handling mechanism mounted on the position adjustment mechanism. A material receiving tray for placing workpieces is provided on the mounting platform. The material handling mechanism includes a mounting plate, on which a first clamping assembly is provided. The first clamping assembly includes a first material handling group: wherein the first material handling group is used to absorb or clamp bolts placed on the receiving tray and install the bolts on the terminals; A detachable mechanism is provided between the mounting plate and the position adjustment mechanism, which includes a fixed plate provided on the position adjustment mechanism and a snap-fit ​​block provided on the mounting plate, the snap-fit ​​block being inserted into the fixed plate; The fixing plate is equipped with a docking component, which is used to connect the snap-fit ​​block to the fixing plate; A locking mechanism is provided on one side of the mounting platform, which is used to tighten the bolts placed on the terminals.

[0007] By adopting the above technical solutions, the two core processes of "material picking / pre-assembly" and "final locking" are separated in space and run in parallel in time, eliminating the waiting time caused by the traditional serial process and significantly shortening the overall production cycle. The detachable mechanism designs the material picking mechanism as a functional module that can be quickly replaced, giving the equipment the potential for rapid model changeover and multi-functionality. The separate design reduces the complexity and weight of individual mechanical ends, which is conducive to improving the motion accuracy and lifespan of the position adjustment mechanism. At the same time, the modular design makes fault diagnosis and maintenance more convenient, and problematic modules can be disassembled individually without affecting the whole machine.

[0008] Optionally, the fixing plate is provided with two snap-fit ​​strips, which cooperate to form a snap-fit ​​groove, and the snap-fit ​​block extends into the snap-fit ​​groove; the docking component passes through the snap-fit ​​groove and is fixed to the snap-fit ​​block.

[0009] By adopting the above technical solution, the detachable connection method of the material handling mechanism and the position adjustment mechanism is specified. The snap-fit ​​groove provides coarse guidance for the connection between the two, which can achieve fast and accurate guidance and positioning. This ensures that the material handling mechanism can achieve extremely high repeatability and positioning accuracy after each disassembly and reassembly, thereby guaranteeing the subsequent assembly quality. This achieves the technical effect of rapid changeover without loss of accuracy. Combined with the overall solution, it can also realize the modularization and flexibility of equipment functions, improve system reliability and maintainability, and fundamentally improve production efficiency.

[0010] Optionally, the snap-fit ​​strip is provided with a protrusion, and the snap-fit ​​block is provided with a slot that matches the protrusion, and the protrusion slides into the slot.

[0011] By adopting the above technical solution, the protrusion on the snap-fit ​​strip matches the slot on the snap-fit ​​block and slides into it, realizing fast and accurate guidance and positioning. It provides a precise error-proof positioning and shear-resistant structure, ensuring that the material handling mechanism has extremely high repeatability positioning accuracy when it is disassembled and reassembled each time, thus guaranteeing the quality of subsequent assembly.

[0012] Optionally, the mating assembly includes a spring pin, which is inserted into the snap-fit ​​block and has external threads on its surface; the fixing plate has a mating hole for the spring pin to pass through, and the inner wall of the mating hole has internal threads; the external threads and internal threads cooperate to fix the spring pin to the fixing plate.

[0013] By adopting the above technical solution, the elastic end of the spring pin continuously applies preload after being inserted into the locking block, eliminating connection gaps and ensuring structural rigidity during operation. The fit between the external thread and the internal thread of the mating hole enables reliable locking and unlocking that can be completed by hand without additional tools, greatly improving the convenience and efficiency of mold changing operations, and achieving the effect of "reliable locking and quick unlocking".

[0014] Optionally, the first clamping assembly further includes a support plate fixedly connected to the mounting plate. The support plate is provided with a first support plate, and the first material picking group is mounted on the first support plate. Each of the first material picking groups includes a mounting frame, a material feeding telescopic cylinder provided on the mounting frame, a material picking tube provided on the mounting frame, and a magnetic suction rod. One end of the magnetic suction rod extends into the material picking tube, and the other end of the magnetic suction rod is provided with a drive plate, which is directly opposite the telescopic shaft of the material feeding telescopic cylinder. The telescopic shaft of the discharge telescopic cylinder extends and retracts, allowing the drive plate to move the magnetic suction rod within the material picking tube. When the magnetic suction rod is in the first working position, the bolt abuts against the material picking tube under the magnetic attraction of the magnetic suction rod. When the magnetic suction rod is in the second working position, the magnetic attraction between the bolt and the magnetic suction rod weakens, and the bolt separates from the material picking tube.

[0015] By adopting the above technical solution, the first material handling group can drive the magnetic suction rod to slide inside the material handling tube through the material release telescopic cylinder, thereby achieving controllable magnetic force and solving the problems of uncontrollable adsorption force of traditional fixed magnets, difficulty in removing bolts, or mutual adhesion. Magnetic attraction avoids mechanical claws from scratching or clamping the bolt threads or surface, achieving non-destructive operation. The clearly defined first working position (strong adsorption) and second working position (weak release) make the material handling process stable and controllable, enabling reliable and non-destructive gripping and release of small-sized bolts.

[0016] Optionally, the first clamping assembly also includes a limited telescopic cylinder, the telescopic shaft of each limited telescopic cylinder being fixed to a mounting frame to control the magnetic suction rod on the mounting frame to participate in or retract from the operation according to the working conditions; the mounting frame connected to the limited telescopic cylinder is provided with a protrusion, and the magnetic suction rod extends into the material picking tube after passing through the protrusion; the two symmetrically arranged mounting frames are staggered relative to each other, and the drive plates on the two magnetic suction rods are staggered relative to each other.

[0017] By adopting the above technical solutions, the overall solution can fundamentally improve production efficiency, achieve modularization and flexibility of equipment functions, and enhance system reliability and maintainability. The first clamping assembly, with its support plate, first support plate, and a first material handling group with a specific structure, enables reliable and non-destructive gripping and release of small-diameter bolts. Furthermore, the first clamping assembly incorporates a limited-length telescopic cylinder, protrusions, a mounting bracket, and a staggered drive plate. This allows for the control of some material handling units to "dormant" or "activate" via the limited-length telescopic cylinder, flexibly adapting to variations in the number of bolts on different terminal products and improving the equipment's versatility. Additionally, the staggered arrangement of the mounting bracket and drive plate solves the interference problem when multiple cylinders and magnetic rods are arranged side-by-side, achieving a compact structure.

[0018] Optionally, the support plate is provided with openings for easy gripping.

[0019] By adopting the above technical solution, openings are provided on the support plate for easy gripping, providing operators with clear force points. This makes it easier to grip and apply force when loading and unloading material modules with a certain weight, reducing operational difficulty and slippage risk, and improving ergonomics and operational safety. At the same time, the device uses the first material handling group of the material handling mechanism to adsorb or clamp bolts and install them onto the terminals, the detachable mechanism to make the material handling mechanism detachable, and the locking mechanism to tighten the bolts. This can fundamentally improve production efficiency, realize modularization and flexibility of equipment functions, and improve system reliability and maintainability.

[0020] Optionally, the material handling mechanism further includes a second clamping component symmetrically arranged with the first clamping component, and the second clamping component is fixed to the mounting plate; the second clamping component includes a second material handling group and a second pressing part, the second material handling group is used to grab the parallel connecting piece on the material receiving tray, and the second pressing part is used to insert the parallel connecting piece into the terminal; wherein, the material handling mechanism can be removed by a detachable mechanism, and the first clamping component and the second clamping component can be switched by rotating the mounting plate.

[0021] By adopting the above technical solution, the overall solution separates the two core processes of "material picking / pre-assembly" and "final locking" in space and allows them to run in parallel in time, eliminating the waiting time of serial processes, shortening the overall production cycle, realizing the modularization and flexibility of equipment functions, and improving system reliability and maintainability; the switchable second clamping component in the single claim allows a single device to switch between "bolt installation mode" and "connecting piece installation mode" through a simple "disassembly-rotation-installation" operation, covering at least two key processes in terminal assembly, reducing production line equipment investment, floor space and operation and maintenance costs.

[0022] Optionally, the position adjustment mechanism includes a first adjustment component, a second adjustment component, and a third adjustment component; the first adjustment component includes a first slide rail disposed on the mounting platform, a first slider slidably disposed on the first slide rail, and a first servo motor for driving the first slider to slide; the second adjustment component includes a second slider fixedly connected to the first slider, a vertical slide plate slidably docked with the second slider, and a second servo motor disposed on one side of the vertical slide plate; a fixed plate is fixedly connected to the vertical slide plate; wherein, the second servo motor can drive the second slider to slide relative to the vertical slide plate; the third adjustment component is fixed by the first slide rail of the support frame to drive the first slide rail to slide on the mounting platform.

[0023] By adopting the above technical solution, the position adjustment mechanism achieves three-axis linkage using a first adjustment component, a second adjustment component, and a third adjustment component. The first servo motor of the first adjustment component drives the first slider to slide on the first slide rail. The second servo motor of the second adjustment component drives the second slider to slide relative to the vertical slide plate. The third adjustment component drives the first slide rail to slide on the mounting platform, enabling the material handling mechanism to be precisely positioned at any point in three-dimensional space. Compared with electric cylinders, it typically has higher positioning accuracy, better speed control, and longer service life, and can flexibly meet the material handling needs of different positions on the material receiving tray and terminal workpieces.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The two core processes of "material picking / pre-assembly" and "final locking" are separated in space and run in parallel in time, eliminating the waiting time caused by serial processes, significantly shortening the overall production cycle time, and fundamentally improving production efficiency; 2. The detachable mechanism designs the material handling mechanism as a "functional module" that can be quickly replaced, solving the problem of fixed functions and difficulty in replacement of traditional equipment. This gives the equipment the potential for rapid model changeover and multi-functionality, realizing modularization and flexibility of equipment functions. 3. Through a simple "disassembly-rotation-installation" operation, it is possible to switch between "bolt installation mode" and "connector plate installation mode", so that a single device can cover at least two key processes in terminal assembly, reducing production line equipment investment, floor space and operation and maintenance costs.

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 12 This application will be described in further detail below. Example

[0028] A terminal workpiece feeding device, as described in the following figure Figure 1 The system includes a mounting platform 1, a position adjustment mechanism mounted on the mounting platform 1, a material picking mechanism mounted on the position adjustment mechanism, and a detachable mechanism 6 for connecting the material picking mechanism and the position adjustment mechanism. The mounting platform 1 is equipped with a receiving tray 2 for placing bolts or parallel connecting pieces. The material picking mechanism includes a first clamping assembly 8 and a second clamping assembly 9. The first clamping assembly 8 is used to absorb or clamp bolts on the receiving tray 2, and the second clamping assembly 9 is used to absorb or clamp parallel connecting pieces on the receiving tray 2. The detachable mechanism 6 allows the material picking mechanism to be separated and disassembled from the position adjustment mechanism. The disassembled material picking mechanism can be rotated to switch its operating mode, thereby enhancing its versatility.

[0029] The position adjustment mechanism includes a first adjustment component 3, a second adjustment component 4, and a third adjustment component 5. The third adjustment component 5 is connected to the first adjustment component 3, the first adjustment component 3 is connected to the second adjustment component 4, and the second adjustment component 4 is connected to the material handling mechanism via a detachable mechanism 6. The third adjustment component 5 can drive the first adjustment component 3 and the second adjustment component 4 to slide along the length of the mounting platform 1, the first adjustment component 3 can drive the second adjustment component 4 to slide along the width of the mounting platform 1, and the second adjustment component 4 can drive the detachable mechanism 6 and the material handling mechanism to slide closer to or further away from the material receiving plate.

[0030] Reference Figure 1 , Figure 2 The third adjustment component 5 includes a third servo motor 502 fixedly connected to the bottom of the mounting platform 1 via a third support plate 501. The rotating shaft of the third servo motor 502 is connected to a drive roller 503 via a belt. One end of the drive roller 503 is connected to a reducer 504, which drives the third screw rod 509 of the reducer 504 to rotate. The third screw rod 509 of the reducer 504 is connected to the bottom of the mounting platform 1 via a bearing.

[0031] Two third slide rails 505 are fixedly connected to the bottom surface of the mounting platform 1, and the third slide rails 505 are arranged along the length of the mounting platform 1. A driven slider 506 is slidably connected to each third slide rail 505. The two driven sliders 506 are fixedly connected by a support frame 507, allowing the two driven sliders 506 to slide synchronously. In addition, a third slider 508 is fixedly connected to the support frame 507, and the third slider 508 is sleeved on the third screw rod 509 of the reducer 504, and the third slider 508 is threadedly connected to the third screw rod 509. This allows the third screw rod 509 to control the sliding of the third slider 508 along the length of the third screw rod 509, the sliding of the driven slider 506 along the length of the third slide rail 505, and the sliding of the support frame 507 along the length of the mounting platform 1 after the third screw rod 509 rotates.

[0032] Two third guide slides are provided on the mounting platform 1. A connecting plate 510 is fixedly connected to both sides of the support frame 507. The two connecting plates 510 pass through the third guide slides on the corresponding sides and slide along the third guide slides under the action of the third servo motor 502.

[0033] Reference Figure 1 , Figure 3 The first adjustment component 3 includes a base plate 301 fixedly connected to the upper ends of two connecting plates 510. A first slide rail 302 is fixed to the top of the base plate 301 by screws. A transmission box 303 is fixed to one end of the first slide rail 302 by screws. A first servo motor 304 is fixed on the transmission box 303, and a gear-chain transmission structure 305 that cooperates with the first servo motor 304 is installed inside the transmission box 303. At the same time, a second guide groove is provided in the first slide rail 302. A bearing is installed on the inner wall of both sides of the second guide groove in the length direction, and a first spiral rod 306 is rotatably installed through the bearings. One end of the first spiral rod 306 extends into the transmission box 303 and cooperates with the gear-chain transmission structure 305, so that when the first servo motor 304 is running, it can drive the first spiral rod 306 to rotate synchronously through the gear-chain transmission structure 305.

[0034] A first slider 307 is threaded through the first helical rod 306 and is connected to the first helical rod 306 by a thread. The first slider 307 abuts against the inner wall of the first guide groove, thereby allowing the first slider 307 to slide along the length of the first guide groove. A sliding plate 308 is fixedly connected to the first slider 307, and the sliding plate 308 is slidably connected to the upper surface of the first slide rail 302.

[0035] Reference Figure 1 , Figure 2 , Figure 4 The second adjustment component 4 includes a vertical sliding plate 401, within which a second guide groove is formed. A second slider 402 is slidably mounted within the second guide groove, and the second slider 402 abuts against the inner wall of the second guide groove. A second servo motor 403 is fixedly connected to the upper end face of the vertical sliding plate 401. The second helical rod of the second servo motor 403 extends into the second guide groove and is threadedly connected to the second slider 402. This allows the second servo motor 403 to drive the second slider 402 to slide along the inner wall of the second guide groove, thereby allowing the second slider 402 to slide relative to the vertical sliding plate 401.

[0036] The second slider 402 is fixed to the sliding plate 308 of the first adjusting component 3 via the fixing block 404, and the second slider 402 and the fixing block 404 cooperate to clamp the vertical slide plate 401. At this time, when the second servo motor 403 drives the second slider 402 to slide relative to the vertical slide plate 401, the second slider 402 remains fixed relative to the fixing plate 601 and the sliding plate 308, and the vertical slide plate 401 slides relative to the fixing plate 601 and the sliding plate 308. That is, the vertical slide plate 401 can slide closer to or further away from the mounting platform 1 under the drive of the second servo motor 403.

[0037] Reference Figure 1 , Figure 4 , Figure 5 The detachable mechanism 6 includes a fixing plate 601, a snap-fit ​​block 602, and a spring pin 603. The fixing plate 601 is fixedly connected to the surface of one side of the vertical slide plate 401 by screws, and the snap-fit ​​block 602 is detachably connected to the fixing plate 601 by the spring pin 603.

[0038] Two snap-fit ​​strips 604 are fixedly connected to the side of the fixing plate 601 away from the vertical sliding plate 401 by screws. The two snap-fit ​​strips 604 and the surface of the fixing plate 601 mate to form a snap-fit ​​groove. Each of the two snap-fit ​​strips 604 has a protruding strip 605 integrally formed on the side facing each other. Additionally, the fixing plate 601 has two mating holes at the location of the snap-fit ​​groove for spring pins 603 to pass through.

[0039] The snap-fit ​​block 602 is fixedly connected to the mounting plate 7 of the material handling mechanism. The snap-fit ​​block 602 has a snap-fit ​​groove that mates with the protrusion 605 and two positioning holes that mate with the docking hole. When the snap-fit ​​block 602 slides into the snap-fit ​​groove and is installed in place, the protrusion 605 extends into the snap-fit ​​groove, and the positioning hole and the docking hole on the same side are on the same axis.

[0040] The outer surface of the spring pin 603 is provided with external threads, and the inner wall of the mating hole is provided with internal threads. The spring pin 603 is fixedly connected to the fixing plate 601 through the threaded engagement with the mating hole of the fixing plate 601. At the same time, after the spring pin 603 is installed in place, its elastic end is inserted into the positioning hole corresponding to the position of the aforementioned mating hole and abuts against the bottom of the positioning hole. The spring pin 603 applies a force to the snap-fit ​​block 602, causing it to slide away from the fixing plate 601, so that the protrusion 605 fits tightly against the inner wall of the slot.

[0041] Reference Figure 1 , Figure 5The material handling mechanism includes a mounting plate 7, a first clamping assembly 8 mounted on the mounting plate 7, and a second clamping assembly 9 mounted on the mounting plate 7. The mounting plate 7 is fixedly connected to the snap-fit ​​block 602 by screws. The first clamping assembly 8 and the second clamping assembly are located on opposite sides of the length of the mounting plate 7. The first clamping assembly 8 is used to absorb bolts placed on the receiving tray 2, and the second clamping assembly 9 is used to clamp parallel connecting pieces placed on the receiving tray 2.

[0042] Reference Figure 5 The first clamping assembly 8 includes a support plate 801 fixedly connected to the mounting plate 7, a first support plate 802 fixedly connected to the support plate 801, and a first material handling assembly disposed on the first support plate 802. The support plate 801 is fixedly connected to the mounting plate 7 by screws, and an opening is provided on the support plate 801 to facilitate maintenance personnel to grasp the support plate 801 and disengage the mounting plate 7 locking block 602 from the detachable mechanism 6.

[0043] Reference Figure 5 , Figure 6 The first support plate 802 is mounted on one side of the support plate 801 with screws. A support column 803 is fixedly connected to both sides of the first support plate 802 with screws, and two limited telescopic cylinders 804 are fixed to both sides of each support column 803 with screws. Furthermore, the first material handling group consists of one stationary material handling group and eight telescopic material handling groups. The stationary material handling group is fixedly connected to the support column 803, and the telescopic material handling groups are fixedly connected to the telescopic shafts of the limited telescopic cylinders 804.

[0044] Reference Figure 6 , Figure 7 The resident material handling team includes a first mounting frame 805, a first material release telescopic cylinder 806 mounted on the first mounting frame 805, a first material handling pipe 807 mounted on the first mounting frame 805, and two first magnetic suction rods 808.

[0045] The two ends of the first mounting bracket 805 are fixedly connected to the corresponding support columns 803 by screws. The bottom of the first mounting bracket 805 is fixed to the first connecting part 8071 of the first material receiving tube 807 by screws via the first strip block 809. The first material discharge telescopic cylinder 806 is installed between the first mounting bracket 805 and the first connecting part 8071 of the first material receiving tube 807 by screws.

[0046] The telescopic shaft of the first feeding telescopic cylinder 806 passes through the first mounting bracket 805, and a first drive plate 810 is fixedly connected to its end. The first drive plate 810 is T-shaped and has a through hole for the first magnetic suction rod 808 to pass through. One end of the first magnetic suction rod 808 passes through the first drive plate 810 and is fixed to the first drive plate 810 by a retaining ring, so that the first feeding telescopic cylinder 806 can drive the first magnetic suction rod 808 to move up and down through the first drive plate 810.

[0047] Reference Figure 1 , Figure 6 , Figure 7 The first picking tube 807 includes a first connecting part 8071 and a first picking part 8072, wherein the first connecting part 8071 of the first picking tube 807 is fixed to the first strip block 809 by screws. The first picking part 8072 of the first picking tube 807 has two first picking slots corresponding to the positions of the first magnetic rod 808, and the other end of the first magnetic rod 808 extends into the first picking slot. In addition, a first limiting ring 811 is fitted onto the outer surface of each first magnetic rod 808, and the first limiting ring 811 is located between the first picking part 8072 of the first picking tube 807 and the first mounting bracket 805, thereby controlling the sliding position of the first magnetic rod 808. Furthermore, when the first limiting ring 811 of the first magnetic suction rod 808 abuts against the surface of the first picking part 8072, the first magnetic suction rod 808 is in the first working position. At this time, the first magnetic suction rod 808 can magnetically attract the bolts on the receiving tray 2 through magnetic attraction, causing the bolts to abut against the surface of the first picking part 8072. When the first limiting ring 811 of the first magnetic suction rod 808 abuts against the surface of the first mounting bracket 805, the first magnetic suction rod 808 is in the second working position. At this time, the magnetic attraction on the first magnetic suction rod 808 is insufficient to attract the bolts abutting against the side of the first picking part 8072 away from the first mounting bracket 805, thereby causing the bolts to fall off the first picking part 8072.

[0048] Reference Figure 6 , Figure 7 The telescopic material handling group includes a second mounting frame 812 mounted on a limited telescopic cylinder 804, a second material discharging telescopic cylinder 813 mounted on the second mounting frame 812, a second material handling tube 814 mounted on the second mounting frame 812, and a second magnetic suction rod 815 slidably mounted inside the second material handling tube 814.

[0049] Reference Figure 5 , Figure 6 , Figure 7The telescopic shaft of the limited telescopic cylinder 804 is fixedly connected to the second mounting bracket 812 by screws. A guide rod 816 is fixed to the second mounting bracket 812 by screws. One end of the guide rod 816 passes through the first support plate 802, allowing the limited telescopic cylinder 804 to drive the second mounting bracket 812 to slide axially along the guide rod 816. This enables the entire telescopic material handling unit to retract or extend.

[0050] Reference Figure 7 , Figure 8 The bottom of the second mounting bracket 812 is fixed to the second connecting part 8141 of the second material receiving tube 814 by screws via the second strip block 817. The second material discharge telescopic cylinder 813 is installed between the second mounting bracket 812 and the second connecting part 8141 of the second material receiving tube 814 by screws.

[0051] The telescopic shaft of the second feeding telescopic cylinder 813 passes through the second mounting bracket 812, and a second drive plate 820 is fixedly connected to its end. The second drive plate 820 has another through hole for the second magnetic suction rod 815 to pass through. One end of the second magnetic suction rod 815 passes through the second drive plate 820 and is fixed to the second drive plate 820 by a retaining ring, so that the second feeding telescopic cylinder 813 can drive the second magnetic suction rod 815 to move up and down through the second drive plate 820.

[0052] The second material picking tube 814 includes a second connecting part 8141 and a second material picking part 8142, wherein the second connecting part 8141 of the second material picking tube 814 is fixed to the second strip block 817 by screws. The second material picking part 8142 of the second material picking tube 814 has a second material picking groove corresponding to the position of the second magnetic suction rod 815, and the other end of the second magnetic suction rod 815 extends into the second material picking groove. In addition, a second limiting ring 818 is fitted on the outer surface of each second magnetic suction rod 815. The second limiting ring 818 is located between the second material picking part 8142 of the second material picking tube 814 and the second mounting bracket 812, thereby controlling the sliding position of the second magnetic suction rod 815. Furthermore, when the second limiting ring 818 of the second magnetic suction rod 815 abuts against the surface of the second picking part 8142, the second magnetic suction rod 815 is in the first working position. At this time, the second magnetic suction rod 815 can magnetically attract the bolts on the receiving tray 2 through magnetic attraction, causing the bolts to abut against the surface of the second picking part 8142. When the second limiting ring 818 of the second magnetic suction rod 815 abuts against the surface of the second mounting bracket 812, the second magnetic suction rod 815 is in the second working position. At this time, the magnetic attraction on the second magnetic suction rod 815 is insufficient to attract the bolts abutting against the side of the second picking part 8142 away from the second mounting bracket 812, thereby causing the bolts to fall off the second picking part 8142.

[0053] Each telescopic material handling unit's second mounting frame 812 has an integrally formed protrusion 819, through which a second magnetic rod 815 extends into the second material handling section 8142. The protrusions 819 on adjacent symmetrically mounted second mounting frames 812 are staggered, allowing the protrusions 819 to insert between adjacent side-by-side second mounting frames 812. This ensures that the second magnetic rods 815 in each telescopic material handling unit are distributed along the same straight line, and the spacing between two adjacent second magnetic rods 815 corresponds to the spacing between two adjacent first magnetic rods 808.

[0054] Meanwhile, the cross-section of the second drive plate 820 is set in a "Z" shape to match the second mounting bracket 812 and the protrusion 819, and to make adjacent two symmetrically distributed second drive plates 820 staggered and interlaced. In addition, the second picking groove of the second picking part 8142 and the through hole on the protrusion 819 are located on the same axis, thereby ensuring that the second magnetic rod 815 can be inserted into the second picking groove of the second picking part 8142 after passing through the protrusion 819.

[0055] Reference Figure 5 , Figure 6 The second clamping assembly 9 includes a second support plate 901, two press-in telescopic cylinders 902, and three pneumatic grippers 903. The housings of the two press-in telescopic cylinders 902 are fixedly connected to the mounting plate 7 with screws, and each press-in telescopic cylinder 902's telescopic shaft is fixedly connected to a telescopic plate 904. The second support plate 901 is fixedly connected to the mounting plate 7 with screws and is L-shaped. The three pneumatic grippers 903 are respectively fixed to the upper surfaces of the two telescopic plates 904 and the second support plate 901 with screws. The pneumatic grippers 903 can mechanically grip the parallel connecting piece placed in the carrier plate, and by driving two of the pneumatic grippers 903 to slide through the press-in telescopic cylinders 902, the parallel connecting piece is inserted into the terminal.

[0056] The implementation principle of Embodiment 1 of this application is as follows: When bolts need to be assembled, the operator uses the detachable mechanism 6 to install the material-taking mechanism integrating the first clamping component 8 to the end of the position adjustment mechanism. After the equipment is started, the position adjustment mechanism works: the third adjustment component 5 drives the support frame 507 and the entire first adjustment component 3 and the second adjustment component 4 to move along the length direction of the mounting platform 1, and roughly positions it above the material receiving plate 2 (bolt area); the first adjustment component 3 drives the vertical slide plate 401 and the material-taking mechanism to move along the width direction of the mounting platform 1, and precisely positions it above the target bolt; the second adjustment component 4 drives the vertical slide plate 401 and the material-taking mechanism to descend vertically, so that the first material-taking part 8072 contacts the bolt.

[0057] At this point, the first clamping assembly 8 operates: the discharge telescopic cylinders in all the first material handling sections 8072 retract, causing the magnetic suction rod to slide upwards to the "first working position." The end of the magnetic suction rod approaches the material handling tube opening, generating a strong magnetic force that firmly attracts the bolt to the end face of the material handling tube. Subsequently, the position adjustment mechanism moves in the opposite direction, moving the material handling mechanism above the terminal workpiece and lowering it again, pre-positioning the bolt in the terminal screw hole. Next, the discharge telescopic cylinder extends, pushing the magnetic suction rod downwards to the "second working position." The end of the magnetic suction rod moves away from the tube opening, the magnetic force significantly weakens, and the bolt separates from the material handling tube under gravity or slight vibration, completing the installation. During the process, the limited telescopic cylinder 804 can control some of the telescopic material handling groups to participate in or withdraw from the operation to adapt to different terminal specifications.

[0058] When switching to assembling parallel connecting pieces, simply release the locking mechanism by pressing the spring pin 603, allowing the entire material handling mechanism to slide out of the snap-fit ​​groove on the fixed plate 601. Rotate the material handling mechanism 180 degrees so that the second clamping assembly 9 faces the working position, then slide it into the snap-fit ​​groove and lock it with the spring pin 603. After switching, the pneumatic gripper 903 of the second clamping assembly 9 can grasp the connecting piece, and the pressing telescopic cylinder 902 presses it into the corresponding terminal position.

[0059] The core of this implementation method lies in the modular and quickly disassembled and replaceable material handling mechanism design, which enables a single device to handle a variety of different workpieces. At the same time, the independent multi-axis position adjustment mechanism ensures the accuracy and efficiency of material handling, greatly enhancing the flexibility and economy of the automated production line.

A fifth servo motor 1102 is fixedly connected to one end of the fifth slide rail 1101. The fifth servo motor 1102 is driven by the fifth slider 1103, so that the fifth slider 1103 slides along the fifth slide rail 1101.

[0063] refer to Figure 10 , Figure 11 , Figure 12 The bolt locking assembly 12 includes a side plate 1201 fixedly connected to the fifth slider 1103. A housing 1202 is fixedly connected to the side plate 1201. A rotary motor 1203 is fixedly connected to one end of the housing 1202. The rotation shaft of the rotary motor 1203 is driven by a first rotating rod 1205 via a coupling 1204. A positioning block 1206 is sleeved and fixedly connected to the first rotating rod 1205. A bushing 1209 is fixedly connected inside the positioning block 1206, and the bushing 1209 passes through the positioning block 1206. A bearing is fixedly connected inside the bushing 1209, and the first rotating rod 1205 passes through the bearing. In addition, a limiting block 1207 is sleeved between the bushing 1209 and the coupling 1204 on the first rotating rod 1205.

[0064] A second rotating rod 1208 is sleeved on the first rotating rod 1205, and the first rotating rod 1205 and the second rotating rod 1208 are fixed together by a first pin. Additionally, the second rotating rod 1208 is fixed to the bushing 1209 by a first damping spring 1210. A third rotating rod 1211 is fixedly connected to the second rotating rod 1208 by a second pin, and the third rotating rod 1211 passes through the housing 1202. A screw 1212 is installed inside the third rotating rod 1211.

[0065] A U-shaped plate 1213 is fixedly connected to the side plate 1201, and a guide block 1214 is fixedly connected inside the U-shaped plate 1213. A pressure plate 1215 is fixed to the U-shaped plate 1213 via a connecting rod, and a second damping spring 1216 is sleeved on the rod. A screwdriver bit 1217 is mounted inside the pressure plate 1215 via a bearing. Furthermore, a screw 1212 passes through the guide block 1214 and is fixedly connected to the screwdriver bit 1217. A buffer sleeve 1218 is sleeved on the portion of the screw 1212 between the pressure plate 1215 and the U-shaped plate 1213.

[0066] Multiple fixing heads 1220 are fixedly connected to the surface of the pressure plate 1215. The fixing head can be inserted into the terminal to be processed to prevent the terminal from shifting when the bolts on the terminal are tightened.

[0067] The implementation principle of Embodiment 2 of this application is as follows: Based on Embodiment 1, this embodiment introduces an independently set locking mechanism. Its workflow is parallel and coordinated with the material handling mechanism to form a highly efficient production line. After the feeding mechanism (first clamping assembly 8) pre-positions the bolt into the screw hole of a certain terminal, the position adjustment mechanism immediately moves away to perform the next feeding or install connecting pieces for other terminals. Simultaneously, the locking mechanism begins operation: its fourth adjustment assembly 10 drives the entire locking mechanism to move parallel to the mounting platform 1 to the vicinity of the terminal; the fifth adjustment assembly 11 performs fine adjustments to ensure the bit 1217 is precisely aligned with the bolt head. Then, the rotary motor 1203 starts, driving the bit 1217 to rotate via the first rotating rod 1205, the second rotating rod 1208, the third rotating rod 1211, and the screw 1212. The pressure plate 1215 presses down under the action of the second damping spring 1216, and its retaining head 1220 inserts into the terminal housing 1202 to prevent rotation, ensuring a stable tightening process. During the rotation and pressing process, the screwdriver bit 1217 achieves constant force or controllable torque bolt fastening through the buffering effect of the first damping spring 1210, the buffer sleeve 1218 and the third damping spring 1219, thus avoiding stripping or over-tightening.

[0068] The key innovation of this implementation lies in changing the two crucial processes of "feeding" and "locking" from the traditional sequential to parallel operations. The material handling mechanism can move to the next workpiece without waiting for tightening to complete, and the locking mechanism can focus solely on tightening. The two mechanisms operate independently yet collaboratively in both space and time, like a miniature assembly line, completely eliminating the waiting time caused by alternating processes in traditional integrated mechanisms, resulting in a revolutionary improvement in production efficiency. The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
