Description

Technical Field

[0001] This invention relates to the field of automated assembly equipment technology, specifically to automated assembly equipment for photovoltaic connector cores. Background Technology

[0002] Photovoltaic connectors are electrical connection components in solar power generation systems. They typically contain a conductive core assembled from a metal core and pins. In automated production, the metal cores are usually supplied as continuous strips wound on a reel. The strip needs to be gradually pulled to the assembly station by assembly equipment, and then the individually supplied pins are pressed into each metal core in sequence. Finally, the core is cut or wound up and discharged.

[0003] Existing assembly equipment suffers from insufficient precision in the conveying of the conveyor belt and the insertion of the pins. In terms of conveying the conveyor belt, conventional equipment typically uses roller friction drive to pull the belt forward. This method is prone to localized slippage during prolonged operation or when the belt is subjected to varying tension at the front and rear ends, leading to deviations in the distance traveled per step. These deviations accumulate during continuous operation, eventually preventing the metal core from accurately positioning itself at the preset assembly coordinates.

[0004] During assembly, the equipment needs to press the pin horizontally into the metal core, a process that generates significant lateral thrust. Existing equipment typically uses simple planar pressure blocks to provide downward vertical clamping force, lacking proper fit and enclosure of the metal core's external geometry. When the metal core is subjected to the impact of this lateral thrust, simple planar friction often fails to completely offset the lateral stress, causing slight lateral slippage or deflection of the metal core within the conveyor track. This momentary positional misalignment during assembly disrupts the coaxiality of the pin and the core hole, easily leading to pin bending, insufficient pressing depth, or metal core deformation, increasing the probability of defective products.

[0005] Furthermore, the manual feeding stage before initial operation of existing equipment is cumbersome, and the guide rails typically lack a flexible clamping structure that can open and close quickly. During the start and stop of intermittent conveying of the belt, due to the lack of continuous and gentle surface friction damping, the belt is prone to local arching or slight backing inside the rail due to inertia or stress release, making it difficult to maintain a stable tension throughout the conveying process, thus affecting the continuous assembly stability of the equipment. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an automatic assembly device for photovoltaic connector cores. It solves the problems of slippage and accumulated positioning errors that easily occur when the existing assembly equipment uses friction drive to pull the material belt. It also solves the problem that conventional planar pressing mechanisms cannot effectively counteract the lateral thrust when the pins are pressed in, resulting in deflection of the metal core and poor assembly coaxiality. In addition, it solves the problem that the lack of a flexible pressing structure in the conveyor track causes the material belt to easily arch and back during intermittent start and stop.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic assembly equipment for photovoltaic connector cores, comprising a worktable, and a filling mechanism, a conveying mechanism, a driving mechanism, a fixing mechanism, a vibratory feeder, an installation mechanism, and a testing machine disposed on the worktable, and a vibratory feeder disposed on one side of the worktable. The filling mechanism is used to install a reel of material carrying a metal core and to wind up the separator paper; the conveying mechanism is used to convey the material strip containing the metal core drawn from the reel; the driving mechanism is located on one side of the conveying mechanism and is used to drive the material strip to move stepwise within the conveying mechanism; the fixing mechanism is located above the conveying mechanism and is used to press down and stabilize the metal core on the material strip; the vibratory feeder is used to automatically feed the pins and feed them to the installation mechanism; as a further embodiment, an extension table is provided on one side of the machine tool, and the vibratory feeder is disposed on the extension table; the installation mechanism is located on one side of the fixing mechanism and is used to push the pins output by the vibratory feeder into the metal core; the testing machine is located at the discharge end of the conveying mechanism and is used to test the metal core.

[0008] The worktable includes a machine tool, a side plate fixedly connected to the outside of the machine tool, and an extension table set on one side of the machine tool. The loading mechanism, conveying mechanism, driving mechanism, and fixing mechanism are all set on the machine tool, while the vibratory feeder is set on the extension table.

[0009] The filling mechanism includes a fixed base fixedly connected to the worktable, a rotating shaft rotatably connected to the fixed base, and a collar sleeved on the rotating shaft, with the material reel sleeved outside the collar. The filling mechanism also includes two partition plates disposed on both sides of the collar, and a pad and a fixing ring sequentially sleeved on the end of the rotating shaft. The fixing ring applies axial restraint to the pad, thus confining the material reel between the two partition plates.

[0010] The conveying mechanism includes two tracks, Track 1 and Track 2, mounted on the workbench, with the conveyor belt passing through their interiors. The conveying mechanism also includes two limiting rollers, Track 1 and Track 2, sequentially positioned on the feed side of Track 2, with the conveyor belt passing through their bottoms. The conveying mechanism further includes a fixed frame positioned above Track 2, with a guide rod slidingly inserted inside the frame. A handle is connected to the top of the guide rod, and a pressure plate is connected to its bottom. A spring is fitted around the guide rod. The pressure plate is located inside Track 2, and the spring's return force drives the pressure plate downwards to flexibly press and limit the conveyor belt.

[0011] The drive mechanism also includes a connecting frame. The first electric push rod is fixed on the worktable, and its output end is connected to the connecting frame. The second electric push rod is installed on the connecting frame, and the output end of the second electric push rod is connected to a positioning plate. The first electric push rod is used to push the connecting frame to move laterally, and the second electric push rod is used to push the positioning plate down and insert it into the gap between adjacent metal cores on the strip. After the positioning plate is inserted, the first electric push rod drives the positioning plate to move laterally, so as to pull the strip to produce step movement.

[0012] The fixing mechanism includes a lift set on the workbench. The output end of the lift is connected to a mounting frame. A hydraulic rod is fixedly installed on the mounting frame by a mounting ring. The bottom output end of the hydraulic rod is connected to a pressure block. The bottom of the pressure block has an adapter slot. The hydraulic rod is used to push the pressure block down so that the adapter slot is engaged with the metal inner core to achieve stability of the metal inner core.

[0013] The installation mechanism includes a pusher mounted on a workbench. The output end of the pusher is connected to an installation pin. A material box is provided on the front side of the pusher, and a material channel is connected above the material box. The pin falls from the vibrating plate into the material box via the material channel. The pusher is used to push the installation pin forward and push the pin located in the material box into the metal core. Specifically, it pushes and installs the pin into the metal core that is already fixed by a fixing mechanism.

[0014] This invention provides an automated assembly device for photovoltaic connector cores. It offers the following advantages: 1. This invention utilizes the coordinated action of two electric push rods to drive a positioning plate directly into the gap between adjacent metal cores on the conveyor belt for mechanical pulling. This rigid insertion and step-by-step pulling method avoids the slippage that easily occurs in traditional friction drives, eliminates the cumulative displacement error of the conveyor belt during long-term conveying, ensures that each metal core can accurately stop at the set assembly position, and improves the overall feeding accuracy of the equipment.

[0015] 2. The fixing mechanism of this invention utilizes a hydraulic rod to drive a pressure block with an adapter slot to move downwards, stably fastening and pressing the metal inner core onto the track before the pin is assembled. The adapter slot matches the outer contour of the metal inner core, providing reliable vertical downward pressure and multi-directional limiting support when the mounting mechanism pushes the pin laterally, effectively counteracting the inner core offset or deflection caused by the lateral assembly thrust, and ensuring the coaxiality and depth consistency of the pin during pressing.

[0016] 3. The conveying mechanism of this invention features a flexible limiting structure consisting of a handle, a guide rod, a spring, and a pressure plate. The operator can widen the gap by lifting the handle to compress the spring, facilitating rapid material feeding onto the track. After feeding, releasing the handle causes the pressure plate to apply continuous downward pressure damping to the conveyor belt under the spring's restoring force. This structure ensures the conveyor belt remains taut while being pulled, preventing it from arching within the track. Simultaneously, it prevents the belt from retracting under stress during the stop interval, maintaining the stability of the conveying process. Attached Figure Description

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides an automated assembly equipment for photovoltaic connector cores, with a workbench 1 as the main supporting base. The workbench 1 includes a machine tool 101, a side plate 102, and an extension table 103. The side plate 102 is fixedly connected to the outer side of the machine tool 101, serving to enclose and protect it and improve the overall frame rigidity. The extension table 103 is independently located on one side of the machine tool 101. The loading mechanism 7, conveying mechanism 5, driving mechanism 8, fixing mechanism 6, mounting mechanism 3, and testing machine 4 are all centrally arranged on the workbench 1 of the machine tool 101, while the vibratory feeder 2, which has its own vibration source, is separately located on the extension table 103. This separated layout effectively cuts off the vibration transmission path, preventing the continuous high-frequency micro-vibrations generated by the vibratory feeder 2 during material handling from interfering with the operating accuracy of the assembly mechanisms on the machine tool 101.

[0021] The loading mechanism 7 is divided into two groups for unwinding the material reel and winding the waste separator paper. The loading mechanism 7 includes a fixed base 701, a rotating shaft 702, and a collar 704. The fixed base 701 is fixed to the table surface of the workbench 1 by bolts. The rotating shaft 702 is horizontally and rotatably connected to the top of the fixed base 701. The collar 704 is coaxially sleeved around the rotating shaft 702. A partition plate 703 is vertically arranged on each of the two axial sides of the collar 704. A pad plate 705 and a fixed ring 706 are sequentially inserted through the end of the rotating shaft 702.

[0022] During installation, the reel containing the metal core is fitted onto the outside of the collar 704 of the filling mechanism 7 on the side away from the worktable 1. The retaining ring 706 is locked to the end of the rotating shaft 702 by threads or snaps, thereby applying an inward axial compressive force to the pad 705, so that the reel is tightly confined between the two partitions 703. The lateral support provided by the partitions 703 can prevent the reel from tilting or scattering when rotating and unwinding. After the reel is drawn out, the separated protective paper end is fixed to the outside of the collar 704 of the filling mechanism 7 on the side closer to the worktable 1. The end of the rotating shaft 702 of the filling mechanism 7 on this side is connected to a servo motor. The servo motor starts intermittently to drive the rotating shaft 702 to rotate, providing stable winding power and preventing the accumulation of waste paper from interfering with the operation of the main conveying area.

[0023] The conveying mechanism 5 provides a guiding path for the movement of the conveyor belt. It includes a first track 501 and a second track 502 fixed to the workbench 1, both of which have a straight channel for the longitudinal sliding of the conveyor belt. A first limit roller 503 and a second limit roller 504 are vertically installed in front of the feed inlet of the second track 502 to limit the height of the conveyor belt and provide initial guidance during the initial introduction.

[0024] A spanning bracket 505 is fixed directly above track 2 502. A guide rod 506 slides vertically through the top plate of the bracket 505. A handle 508 is connected to the top of the guide rod 506, and the bottom extends into the track 2 502 and is connected to a pressure plate 507. A spring 509 is sleeved on the outside of the guide rod 506. The spring 509 is compressed and restricted between the top surface of the bracket 505 and the top surface of the pressure plate 507. Under the continuous expansion and restoring force of the spring 509, the pressure plate 507 presses downward against the surface of the material belt inside the track, forming a flexible pressing structure. This structure provides moderate frictional damping during material belt conveying, allowing the material belt to slide, while preventing the material belt from backing up or arching locally due to the release of its own stress when pulling stops. When manually threading the material, lifting the handle 508 can overcome the elastic force of the spring 509 to lift the pressure plate 507, making the threading gap easier to operate.

[0025] The drive mechanism 8, located on one side of the conveyor track, provides stepping power. It includes an electric push rod 801 horizontally fixed to the worktable 1 parallel to the conveying direction. The horizontal output end of the electric push rod 801 is connected to a connecting frame 802. An electric push rod 803 is vertically mounted on the connecting frame 802. The vertical output end of the electric push rod 803 is connected downwards to a positioning plate 804. The thickness of the positioning plate 804 is adapted to the physical distance between adjacent metal cores on the conveyor belt. During operation, the electric push rod 801 extends, causing the connecting frame 802 to move laterally. Then, the electric push rod 803 pushes the positioning plate 804 downwards, precisely inserting it into the gap between adjacent metal cores. After insertion, the positioning plate 804 forms a mechanical lock. At this point, the electric push rod 801 retracts and resets, and the positioning plate 804 pulls the conveyor belt to generate stepping movement. This rigid solid insertion-based pulling method replaces the traditional surface friction traction, fundamentally eliminating slippage and ensuring the consistency of the single conveying distance.

[0026] The fixing mechanism 6 is located directly above the assembly station and includes a lift 601 vertically fixed on the workbench 1. The output end of the lift 601 is connected to a mounting bracket 602 extending above the track. A hydraulic rod 603 is vertically fixed to the mounting bracket 602 via a mounting ring 604. The bottom output end of the hydraulic rod 603 faces the metal inner core below and is connected to a pressure block 605. The bottom surface of the pressure block 605 is machined with a matching groove according to the external geometric contour of the metal inner core. When the hydraulic rod 603 is working, it pushes the pressure block 605 downward, so that the matching groove partially covers and engages with the surface of the metal inner core on the strip. This structure provides multi-directional physical restraint, which can effectively resist the large thrust generated when the subsequent pin is inserted, maintain the stability of the inner core's position within the track, and avoid coaxiality deviation.

[0027] The mounting mechanism 3 is located on a side table of the fixing mechanism 6, and a vision sensor is installed on the upper bracket of the mounting mechanism 3. The mounting mechanism 3 includes a pusher 301 horizontally mounted on the workbench 1. The output shaft of the pusher 301 is coaxially aligned with the insertion hole of the metal core at the assembly station, and the output end is connected to the mounting pin 302. A receiving box 303 is fixedly mounted on the front side of the pusher 301, and an inclined material channel 304 is connected above the material box 303. The other end of the material channel 304 is connected to the discharge port of the vibratory feeder 2. The vibratory feeder 2 conveys the straightened pins sequentially through the material channel 304 into the material box 303. Before assembly, the vision sensor verifies the current position coordinates of the metal core; after confirmation, the pusher 301 pushes the mounting pin 302 horizontally forward, pushing the pin that has fallen into the material box 303 into the hole of the metal core secured by the fixing mechanism 6.

[0028] The inspection machine 4 is positioned across the discharge end track of the conveyor mechanism 5. The internally integrated inspection probe faces inward towards the track and is used to perform an integrity scan on the assembled metal cores that pass through this area, promptly identifying the location of defective products with missing pins and controlling the quality of the finished products output by the equipment.

[0029] Working Principle: When using this equipment for automatic assembly of photovoltaic connector cores, the overall process is as follows: First, the pins to be installed are placed in batches inside the vibratory feeder 2 for automatic material handling and feeding; simultaneously, the tape reel carrying the metal cores is fixed to the feeding side of the filling mechanism 7, and the tape is pulled out and passed through the conveying mechanism 5. After the equipment starts, the drive mechanism 8 pulls the tape in the conveying mechanism 5 in intermittent stepping movements; during the intervals when the tape stops moving, the fixing mechanism 6 presses down to stabilize the metal core at the current station, while the installation mechanism 3 moves to press the pins into the core; as the drive mechanism 8 continues to step and pull, the assembled semi-finished products move to the inspection machine 4 for quality inspection to avoid missing pins; finally, the qualified finished tape is continuously discharged from the end of the conveying mechanism 5, thus completing the automated assembly. When installing the tape reel, first operate the loading mechanism 7 on the side away from the workbench 1: remove the retaining ring 706 from the end of the rotating shaft 702 to release the axial restriction on the pad 705. Then, remove the pad 705 along with the outer partition 703 from the rotating shaft 702, exposing the collar 704 fitted on the rotating shaft 702. Fit the rolled tape reel onto the collar 704, and then reinstall the partition 703, pad 705, and retaining ring 706 in sequence, so that the tape reel is firmly restricted between the two partitions 703, preventing it from loosening and slipping off during rotation and unwinding. After the material reel is installed, lead out the front end of the material strip and separate the protective paper from the metal core material strip; then, following the same disassembly and assembly method as described above, open the loading mechanism 7 on the side near the workbench 1, fix one end of the separated paper onto the collar 704 on this side and restore the assembly in preparation for subsequent waste paper winding. When threading material onto the conveyor track, one end of the material strip is passed sequentially through the bottom of the first limiting roller 503 and the second limiting roller 504. At this time, the operator lifts the handle 508, causing the guide rod 506 to slide upward inside the fixed frame 505. This forces the spring 509 sleeved on the outside of the guide rod 506 to deform under pressure. Simultaneously, the pressure plate 507 connected to the bottom of the guide rod 506 moves upward inside the second track 502, creating a material threading gap between it and the inner bottom wall of the second track 502. The material strip is then passed through this gap and extended to the bottom of the positioning plate 804. Afterward, the handle 508 is released, and the pressure plate 507, under the restoring force of the spring 509, flexibly presses and limits the material strip downward. When the drive mechanism 8 is activated to move the conveyor belt, electric push rod 801 pushes the connecting frame 802 to move, and simultaneously moves electric push rod 803. After completing the lateral displacement, electric push rod 803 pushes the positioning plate 804 downward and inserts it into the gap of the metal core inside the conveyor belt. After insertion, electric push rod 801 drives the connecting frame 802 to perform lateral reset. At the same time, under the constraint of the positioning plate 804, it pulls the conveyor belt to move between track 501 and track 502. After the shift is completed, the electric push rod 803 drives the positioning plate 804 to reset. At this time, the electric push rod 801 pushes the connecting frame 802 to shift again and repeats the initial shift steps. With the cooperation of the electric push rod 801 and the electric push rod 803, one end of the material strip achieves the effect of intermittent shift. As the material strip continues to move, the separator paper in the material strip reel will continue to separate from the material strip. At the same time as the separation, the servo motor in the winding side filling mechanism 7 will start intermittently, driving the rotating shaft 702 on that side to rotate and rewind the separator paper. After the equipment is started, the drive mechanism 8 achieves intermittent displacement of the material strip through coordinated actions in a rectangular coordinate system: First, electric push rod 801 extends, pushing the connecting frame 802 to perform lateral idle displacement, and simultaneously driving electric push rod 803 to move to the gripping position; after the lateral displacement is completed, electric push rod 803 extends downward, pushing the positioning plate 804 to move down and accurately insert into the gap between the metal cores inside the material strip, forming a mechanical lock; after insertion, electric push rod 801 retracts in the opposite direction, driving the connecting frame 802 to return to its lateral reset. At the same time, under the mechanical pull of the positioning plate 804, the material strip undergoes a single step displacement in the discharge direction inside track 501 and track 502; after the single displacement is completed, electric push rod 803 retracts, driving the positioning plate 804 to move up and reset, disengaging from the material strip. Then, electric push rod 801 extends again to repeat the above cyclic steps. When the conveyor belt finishes a single displacement and comes to a standstill in track 501, the fixing mechanism 6 engages. The hydraulic rod 603 pushes the bottom pressure block 605 downward, and the metal core on the track is precisely locked and pressed through the matching slot at the bottom of the pressure block 605, preventing it from shifting or shaking when subjected to assembly force. After the inner core is fixed, the vision sensor on the mounting mechanism 3 verifies and positions the current metal inner core. After the positioning is correct, the pusher 301 moves to push the mounting pin 302 forward, pushing the pin that fell from the vibrating plate 2 into the material box 303 via the material channel 304 into the metal inner core. After a single pin is installed, the hydraulic rod 603 drives the pressure block 605 to move upward and reset, releasing the restriction on the material strip. Subsequently, the material strip continues to move under the traction of the drive mechanism 8. The assembled metal core moves to the front of the inspection machine 4 for assembly integrity inspection to avoid missing or defective products. After the inspection is completed, the material strip is discharged from the end of the conveyor mechanism 5.
