Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to a device for inserting WLAN cards and WLAN rubber into an adapter box, and more particularly to an automated system and assembly method for dual-line feeding integrated assembly. Background Technology

[0002] With the rapid development of 5G communication, the Internet of Things, and smart terminal devices, the demand for wireless network modules (such as WLAN cards) and their supporting components (such as WLAN rubber) has surged. The requirements for assembly precision and efficiency in precision electronic devices such as adapter boxes are also increasing. Traditional assembly methods mainly rely on manual operation or single-line semi-automatic equipment, which has the following significant drawbacks:

[0003] Inefficiency and lack of integration: The manual handling, sorting, positioning and assembly processes are cumbersome, and the multiple processes are scattered, resulting in long production lines, low material flow efficiency, and difficulty in meeting the needs of large-scale production.

[0004] Positioning accuracy is difficult to guarantee: Operators need to repeat high-precision actions for a long time, which leads to fatigue accumulation and affects the stability and consistency of the operation. Manual operation is easily affected by fatigue and experience differences. Existing equipment lacks multi-level vision and laser collaborative positioning capabilities, making it difficult to accurately control the gripping of small parts (such as WLAN rubber) and the assembly position on the workpiece station, which can easily lead to quality problems such as assembly misalignment.

[0005] Poor flexibility and adaptability: The material trays come in various sizes and specifications, and the traditional feeding mechanism lacks adaptive adjustment function. When changing product models, the mechanical structure needs to be adjusted frequently, resulting in long downtime and restricting the ability to produce multiple varieties on a mixed production line.

[0006] Low stability and automation: There are many manual intervention links, and material supply and pallet positioning rely on manual monitoring, which can easily lead to problems such as material supply interruption and pallet displacement, resulting in unstable assembly cycle and large fluctuations in yield.

[0007] While some automated assembly equipment exists in the current market, it largely focuses on feeding single components or simple assembly, and has not yet effectively solved the integration challenges of synchronous and precise feeding of heterogeneous components (such as WLAN cards and WLAN rubber), real-time spatial orientation compensation, and highly stable cyclic assembly. In the context of intelligent manufacturing upgrades, there is an urgent need for a fully automated integrated assembly system that can deeply integrate dual-line feeding, adaptive adjustment, and closed-loop conveying to overcome existing technological bottlenecks.

[0023] An assembly method for an automated system with dual-line feeding and integrated assembly includes the following steps:

[0024] A. Loading the WLAN card:

[0025] S1. Place a stack of WLAN card trays filled with WLAN cards on the two belts of the feeding and conveying module. The two belts run synchronously to transfer the stack of WLAN card trays to the lifting plate of the lifting module. The lifting motor of the lifting module drives the servo transmission component to lift the lifting plate and lift the stack of WLAN card trays to the top operating platform.

[0026] S2, X slide cylinder drives the suction device to move horizontally along the X direction, Y slide cylinder drives the suction device to move horizontally along the Y direction, Z slide cylinder drives the suction device to move up and down along the Z direction, rotary motor drives the suction device to rotate the angle, the suction device picks up the WLAN cards in the WLAN card tray one by one, the secondary positioning platform rises, and the suction device moves the WLAN cards onto the positioning fixture of the secondary positioning platform;

[0027] S3. After all the WLAN cards in the WLAN card tray are emptied, the X-slide cylinder drives the suction cup to move horizontally along the X direction, so that the suction cup moves above the empty WLAN card tray. The lifting motor drives the suction cup to descend, and the suction cup picks up the empty WLAN card material and transfers it to the empty tray placement position through the X-slide cylinder.

[0028] B. Loading wlan rubber:

[0029] S1. The feed roll of the feeder releases the material belt. The material belt passes through the edge of the peeling blade and peels the wlan rubber on the material belt to the unloading plate. The position of the wlan rubber on the unloading plate is specifically sensed by the material sensor.

[0030] S2. The strip of material that has been stripped is then wound up by the take-up reel;

[0031] C. Dual-material assembly:

[0032] S1. The robot moves to the secondary positioning platform and picks up the WLAN card on the positioning fixture through the suction picker. Then the robot moves to the unloading plate of the feeder and picks up the WLAN rubber through the clamping picker.

[0033] S2. The robot, carrying the WLAN card and WLAN rubber, moves above the lower vision positioning module and uses the lower camera to photograph the WLAN card and WLAN rubber to determine the robot's fixed position on the WLAN card and WLAN rubber.

[0034] S3. The feeding belt transports the product pallet containing the workpiece to the positioning and installation station. The blocking module prevents the product pallet from moving forward, and the fixing module clamps and fixes the product pallet on both sides. The workpiece has a first accessory station and a second accessory station.

[0035] S4. The robot moves to the top of the product tray. The upper vision positioning and scanning module takes a picture of the first component station of the workpiece to determine the planar positioning of the first component station. The point laser height measuring instrument measures the height of the first component station of the workpiece to determine the height positioning of the first component station. The robot's gripper loads the WLAN rubber into the first component station.

[0036] Then, the upper vision positioning and scanning module takes a picture of the second part station of the workpiece to determine the planar positioning of the second part station; the point laser height measuring instrument measures the height of the second part station of the workpiece to determine the height positioning of the second part station; the robot's suction picker puts the WLAN card into the second part station; the upper vision positioning and scanning module takes a picture of the WLAN card to scan the QR code on the WLAN card.

[0037] S5. After all the workpieces in the product tray have been installed with accessories, the material setting module resets and releases the product tray, the material blocking module lifts and releases the product tray, and the feeding belt continues to transport the product tray forward.

[0038] Preferably, the starting motor drives the lead screw to rotate forward or reverse, the guide block drives rack one to move one side of the belt outward or inward, rack one synchronously drives the intermediate gear to rotate, the intermediate gear synchronously drives rack two to move the other side of the belt outward or inward, thus completing the adjustment operation of widening or narrowing the gap between the two belts.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] Improving assembly efficiency and capacity: By operating in parallel with dual feeding lines (the first feeding line handles WLAN cards and the second feeding line handles WLAN rubber), combined with synchronous material handling and assembly by robots, the efficiency of material flow and the degree of assembly automation are significantly improved. The product circulation mechanism realizes the automated circulation transport of workpiece pallets (with the feeding belt and return belt working together), and the clamping, fixing and releasing of the positioning and installation station are automatically connected, greatly improving continuous production capacity and realizing the continuous and efficient integrated assembly of two different parts (WLAN cards and WLAN rubber).

[0041] Improve assembly accuracy and yield: Multi-level vision positioning system: The upper vision positioning scanning module (including a ring light source) captures real-time images of the workpiece / part station to accurately determine its planar position; the lower vision positioning module (including a strip light source) performs a secondary verification of the robot's material-grabbing position before assembly; QR code scanning enables product traceability and quality monitoring. Height compensation technology: A point laser height gauge dynamically detects the workpiece station height and automatically compensates for product tray thickness errors, ensuring precise matching of the assembly positions of the WLAN card and WLAN rubber.

[0042] Enhanced system adaptability and flexibility: The adjustable spacing design of the multi-axis feeding machine: The spacing between the two belts is adjusted synchronously by driving the rack and pinion linkage mechanism through the adjustable spacing motor, which is compatible with different specifications of WLAN pallets and can quickly adapt to diverse production needs without changing hardware.

[0043] Multifunctional robot actuator: integrates adsorption picker (vacuum suction head), gripper (pneumatic gripper), vision and height measurement module, can handle irregularly shaped and soft and hard materials (such as WLAN cards and WLAN rubber) at the same time, and adapt to complex assembly scenarios.

[0044] Achieve full-process automation and integration: Material handling automation: Multi-axis feeders automatically complete material tray conveying, lifting, material picking, and empty tray recycling; feeders automatically peel the WLAN rubber off the material belt through peeling blades, and accurately position it in conjunction with material sensors.

[0045] Closed-loop assembly process: from dual-line material supply → robot material picking → vision positioning → precise assembly → product cycle output, the entire process requires no manual intervention, and all modules are integrated into a unified housing, reducing space occupation and external interference.

[0046] Optimize resource utilization and ease of maintenance: The secondary positioning platform uses X / Y side-push cylinders and stop bars to quickly clamp and fix the WLAN card, reducing positioning errors; the empty material tray is automatically moved to the designated position, and the waste strip is automatically recycled by the take-up roll, reducing material management costs; the modular design (such as multi-dimensional drive modules and standard cylinder components) facilitates maintenance, replacement and system upgrades.

[0047] In summary, this invention effectively solves the efficiency bottleneck and precision problems in the assembly of irregularly shaped parts through dual-line material feeding collaboration, multi-level visual positioning, adaptive mechanical structure, and full-process automation design. It significantly improves production flexibility, reduces reliance on manual labor, and is applicable to high-precision assembly fields such as electronic components. Attached Figure Description

[0061] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0062] like Figure 1 and 2As shown, an automated system for integrated assembly with dual-line feeding includes a first feeding line and a second feeding line. The first and second feeding lines are connected by a robot 7, which picks up materials and converges them at the positioning assembly output line. The first feeding line sequentially includes a multi-axis moving feeder and a secondary positioning platform 5. The second feeding line includes a feeder 6. Figure 9 and 10 As shown, the execution end of robot 7 is equipped with an adsorption picker 701, a clamping picker 702, a point laser height measuring instrument 703, and an upper vision positioning scanning module. The positioning assembly output line includes a lower vision positioning module 8 and a product circulation mechanism in sequence. The product circulation mechanism is equipped with a positioning installation station. The positioning installation station is equipped with a material fixing module and a material blocking module. The execution end of robot 7 is coordinated with feeder 6, secondary positioning platform 5, lower vision positioning module 8, and positioning installation station in sequence.

[0063] Robot 7 specifically adopts a six-axis assembly robot. The point laser height measuring instrument 703 is an existing product and can be purchased as a finished product for assembly and application, so it will not be described in detail here. The overall system includes an external housing, a multi-axis running feeder, a secondary positioning platform 5, a feeder feeder 6, a robot 7, a lower vision positioning module 8, and a product circulation mechanism, all housed inside the housing, forming an integrated, fully automated assembly equipment.

[0064] like Figure 3 As shown, preferably, the multi-axis operating feeder includes a housing with a top operating platform. A conveying port communicating with the inner cavity of the housing is opened on the top operating platform. A feeding opening is provided on one side of the housing. A feeding conveying module 1 is provided extending inward from the feeding opening. A lifting module 3 is provided extending upward from the inner end of the feeding conveying module 1. The top of the lifting module 3 is connected to the conveying port. A multi-dimensional drive module 4 is provided on the outer periphery of the conveying port on the top operating platform. A suction device 407 and a suction cup 411 are driven on the multi-dimensional drive module 4. An empty tray placement position is provided on the side of the conveying port on the top operating platform.

[0065] like Figures 3 to 5As shown, the feeding and conveying module 1 includes a feeding motor 101 and a feeding transmission assembly. The feeding transmission assembly includes two drive shafts 102 hinged to the inner cavity of the housing. Pulleys are sleeved on the drive shafts 102, and belts 103 are sleeved on each pair of corresponding pulleys. The rotating shaft of the feeding motor 101 drives and connects to either drive shaft 102. The two drive shafts 102 are arranged parallel to each other at the bottom of the inner cavity of the housing. One drive shaft 102 is close to the feeding opening, and the other drive shaft 102 is close to the lifting module 3. Two pulleys are symmetrically sleeved on each drive shaft 102. The pulleys at corresponding positions on the two drive shafts 102 form a set. The belts 103 extend horizontally from the feeding opening to the lifting module 3. A stack of WLAN trays is placed on two belts 103. The presence of WLAN trays is detected by the material sensor between the two belts 103, and the feeding motor 101 is started to drive a drive shaft 102 to rotate in a specific direction. The friction between the pulley and the belt 103 transmits the power, causing the two belts 103 to operate synchronously and move the stack of WLAN trays to the lifting module 3.

[0066] like Figure 5 As shown, a lifting and blocking assembly is provided between the two belts 103. The lifting and blocking assembly includes a blocking cylinder 104. The telescopic end of the blocking cylinder 104 is fixedly connected to a blocking plate 105. When the blocking plate 105 exceeds the conveying height of the belt 103, it forms a blocking state. When the blocking plate 105 is lower than the conveying height of the belt 103, it forms a releasing state. When two stacks of WLAN pallets are placed on the two belts 103 one after the other, the blocking plate 105 is lowered to the releasing state, so that the first stack of WLAN pallets passes through and reaches the lifting module 3. Then the blocking plate 105 is raised to the blocking state to stop the second stack of WLAN pallets from moving forward. After the lifting module 3 lifts and removes the first stack of WLAN pallets, the blocking plate 105 is lowered to release the second stack of WLAN pallets.

[0067] like Figure 6As shown, the lifting module 3 includes a lifting motor 301, a servo transmission assembly, and a lifting plate 305. The servo transmission assembly includes a vertical lead screw 302 driven and connected by the lifting motor 301. The vertical lead screw 302 is hinged to the upright frame via bearings. A vertical rail 303 parallel to the vertical lead screw 302 is provided on the upright frame. A lifting block 304 is sleeved on the vertical lead screw 302 to form a threaded engagement connection. The lifting block 304 is engaged with the vertical rail 303 via a slide groove to form a guide sliding connection. The lifting plate 305 is fixedly connected to the outside of the lifting block 304. The lifting plate 305 is arranged between two belts 103. A stack of WLAN pallet trays is conveyed to the lifting plate 305 via the belts 103. The lifting motor 301 is started to drive the vertical lead screw 302 to rotate in the forward direction via a reducer. The threaded engagement transmission drives the lifting block 304 to drive the lifting plate 305 to rise along the vertical rail 303, raising the stack of WLAN pallet trays above the conveyor. During the return trip, the lifting motor 301 is started to drive the vertical lead screw 302 to rotate in the opposite direction, causing the lifting block 304 to lower the lifting plate 305 to the same height between the two belts 103.

[0068] like Figure 3 and 4 As shown, the multi-dimensional drive module 4 includes X-braces 401 fixed on both sides of the conveyor port. One X-brace 401 is equipped with an X-slide cylinder 402, and the other X-brace 401 is equipped with an X-slide rail 403. A Y-slide cylinder 404 is driven and connected to the X-slide cylinder 402. The Y-slide cylinder 404 is connected to the X-slide rail 403 via an X-slide block to form a guide connection. A Z-slide cylinder 405 is driven and connected to the Y-slide cylinder 404. A suction seat is fixed to the lifting end of the Z-slide cylinder 405. A rotary motor 406 is mounted on the suction seat, and the rotary motor 406 rotates to drive the suction device 407. The X-slide cylinder 402, Y-slide cylinder 404, Z-slide cylinder 405, and rotary motor 406 are all existing products and can be purchased and directly installed for use. The rotary motor 406 can directly drive the suction device 407, or it can achieve rotation through a transmission belt, gears, or other transmission methods. The suction device 407 can be connected to a vacuum device, and the product is adsorbed through the suction nozzle at the bottom of the suction device 407. The suction device 407 is driven to move horizontally in the X direction by the X-slide cylinder 402, horizontally in the Y direction by the Y-slide cylinder 404, and vertically in the Z direction by the Z-slide cylinder 405. The suction device 407 is rotated by the rotary motor 406, thereby moving the suction device 407 to any position within the WLAN material tray. The suction and discharge operations are achieved through lifting and lowering.

[0069] like Figure 3 and 4As shown, a Z-axis frame is fixed to the Y-axis slide cylinder 404. A drive wheel and a driven wheel are hinged on the Z-axis frame. A lifting belt 409 is sleeved on the outer periphery of the drive wheel and the driven wheel. The drive wheel is driven and connected by a lifting motor 408. A lifting frame 410 is fixed to the lifting belt 409 through a connecting block. A Z-axis slide rail is set on the Z-axis frame. The lifting frame 410 is connected to the Z-axis slide rail through a Z-slider to form a guide connection. A suction cup 411 is fixed to the bottom end of the lifting frame 410. A lifting device is also set on the lifting frame 410. A fork plate is fixed to the lifting end of the lifting device. The starting motor 408 drives the drive wheel to rotate forward, which in turn drives the lifting belt 409 and the driven wheel to rotate forward, simultaneously causing the lifting frame 410 to descend along the Z-slide rail, and the suction cup 411 descends to pick up the empty material tray. The starting motor 408 also drives the drive wheel to rotate in the opposite direction, causing the lifting belt 409 and the driven wheel to rotate in the opposite direction, simultaneously causing the lifting frame 410 to rise along the Z-slide rail, and the suction cup 411 lifts the empty material tray. The lifting mechanism drives the fork plate to perform lifting and lowering actions.

[0070] like Figure 4As shown, preferably, the pulley is mounted on the base frame via a bearing, and the belt 103 is sleeved on the pulley, so that the belt 103 is mounted on the base frame to form a cyclic operation. A spacing adjustment mechanism 2 is provided between the two base frames. The spacing adjustment mechanism 2 includes a spacing adjustment motor 201, which drives a connecting screw 203. A guide block 204 is sleeved on the screw 203 to form a threaded engagement connection. A guide rail is fixed parallel to one side of the screw 203. The guide block 204 is engaged with the guide rail through a slot to form a sliding connection. The guide block 204 is fixedly connected to a rack 205. The outer end of the rack 205 is fixedly connected to one of the base frames. The rack 205 is engaged with an intermediate gear 206 through gear engagement. The intermediate gear 206 is engaged with a rack 207 through gear engagement. The outer end of the rack 207 is fixedly connected to another base frame. A track 208 and a track 209 are fixed parallel to both sides of the rack 205 and the rack 207. The base frame is engaged with the track 208 through a slide block to form a sliding connection. The base frame is engaged with the track 209 through a slide block to form a sliding connection. The adjustable-pitch motor 201 is connected to the lead screw 203 via a belt assembly. The belt assembly includes a driving pulley and a driven pulley. The driving pulley and the driven pulley are tensioned and fitted with a transmission belt 202. The shaft of the adjustable-pitch motor 201 is fixed to the driving pulley, and the driven pulley is fixedly fitted onto one end of the lead screw 203. The belt assembly is prior art and will not be described in detail here. When the adjustable-pitch motor 201 is started, it drives the lead screw 203 to rotate in a specific direction via the belt assembly. The guide block 204 on the lead screw 203 drives the rack 205 to move along the guide rail, and at the same time pushes the base frame at the outer end of the rack 205 to move, so that the belt 103 on the base frame moves synchronously. During the movement, rack 205 drives intermediate gear 206 to rotate through tooth meshing. Intermediate gear 206 then drives rack 207 to move. Rack 207 moves in the opposite direction to rack 205. Rack 207 simultaneously pushes the base frame and belt 103 at its outer end to move. During the movement of the two base frames, it slides along track 208 and track 209 to improve stability. This achieves the effect of simultaneously widening or narrowing the gap between the two belts 103 to accommodate the transportation of Wlan pallets of different specifications.

[0071] like Figure 7As shown, preferably, the secondary positioning platform 5 includes a lifting device 501, specifically a lifting cylinder. A lifting platform 502 is fixed on the upward-facing telescopic end of the lifting device 501. A positioning fixture 503 is provided on the top surface of the lifting platform 502. A through groove is opened in the top surface of the positioning fixture 503, and a material sensor is placed in the through groove. An X-stop bar 504 is provided on one X side of the positioning fixture 503, and an X-side push cylinder 505 is provided on the other X side. A Y-stop bar 506 is provided on one Y side of the positioning fixture 503, and a Y-side push cylinder 507 is provided on the other Y side. The lifting platform 502 has a total of two positioning fixtures 503, which can simultaneously fix two WLAN cards. The material sensor is an existing product that can be directly purchased and used, and its transmission of the sensing signal to the controller, which controls the action of the side push cylinder, is an application of existing technology. The lifting device 501 raises the lifting platform 502 closer to the bottom of the suction device 407 so that the suction device 407 can place the WLAN card in the correct position on the positioning fixture 503. The material sensor detects that the WLAN card has been placed, and the X-side push cylinder 505 and Y-side push cylinder 507 simultaneously push the WLAN card to abut against the X-bar 504 and Y-bar 506 to form a clamping and positioning.

[0072] like Figure 8As shown, preferably, the feeder 6 includes a frame, on which a feed roll 601, a take-up roll 602, and at least one tension roller 603 are hinged. The take-up roll 602 is driven and connected by a take-up motor. A base 604 is fixed on the frame, and a stripping blade 605 is movably mounted on the base 604. The edge of the stripping blade 605 connects to a discharge plate 606, and a stripping gap is formed between the edge of the blade and the discharge plate 606. Several grooves are opened on the discharge plate 606, and a material sensor is provided below each groove. A strip is wound on the feed roll 601, and the strip extending from the strip passes sequentially through the tension roller 603, the top surface of the stripping blade 605, and the edge of the blade, and then passes out from below the stripping blade 605 and is wound onto the take-up roll 602. A hinge shaft is threaded through the end of the stripping blade 605 furthest from the blade edge. A corresponding hinge notch is provided on the top of the base 604. The hinge shaft is inserted into the hinge notch to form a rotatable connection. An overlapping shaft is threaded through the end of the stripping blade 605 closest to the blade edge, and the overlapping shaft rests on the top edge of the base 604. A lifting handle is hinged to the side of the base 604. The lifting end of the lifting handle contacts the bottom wall of the overlapping shaft. Pressing down the driving end of the lifting handle and rotating it raises the overlapping shaft, causing the end closest to the blade edge to swing upward around the hinge shaft. This allows the material strip to pass through the blade edge along the top surface of the stripping blade 605 and into the space below, completing the material strip feeding function. The feeder 6 is an existing product that can be purchased and used directly. Its application principle and method are existing technology, so they will not be described in detail here. The take-up motor is started, driving the take-up roll 602 to rotate in a specific direction, continuously winding the material strip. The strip is released from the feed roll 601, passes through two tension rollers 603 to achieve tension, and moves forward along the top surface of the stripping blade 605. As it passes through the stripping gap, the blade edge cooperates with the unloading plate 606 to create a scraping action, peeling off the WLAN rubber adhering to the strip and moving it onto the unloading plate 606. A material presence sensor specifically detects the position of the WLAN rubber on the unloading plate 606, allowing the robot 7 to accurately pick it up. The material presence sensor is an existing product and can be purchased and used directly.

[0073] like Figure 9 and 10As shown, preferably, the adsorption picker 701 includes a vacuum head, the bottom of which is connected to a suction head; the clamping picker 702 includes a clamping cylinder, which drives a pair of grippers to open and close; the upper vision positioning scanning module includes an upper camera, the upper lens 704 of which is arranged downwards, and a ring light source 705 is arranged below the upper lens 704. The adsorption picker 701, clamping picker 702, point laser height gauge 703, upper camera, and upper lens 704 are all existing products and can be purchased and used directly. The adsorption picker 701 is connected to an external vacuum device through a pipeline, and uses its suction head to adsorb WLAN cards. Two clamping pickers 702 are arranged side by side, and the grippers of the clamping pickers 702 grasp the WLAN rubber. The point laser height gauge 703 measures the height position of the workpiece in the product tray. The upper camera takes a picture of the planar position of the bow and arrow, or captures the QR code on the workpiece for identification and recording.

[0074] like Figure 11 As shown, preferably, the lower vision positioning module 8 is arranged between the secondary positioning platform 5 and the product circulation mechanism. The lower vision positioning module 8 includes a frame 801, and a lower camera 802 is arranged inside the frame 801 with its lower lens facing upwards. A strip light source 803 is mounted on the side of the frame 801 above the lower lens. When the robot 7 grasps the product and passes above the lower camera 802, the lower camera 802 takes a picture of the product, thereby accurately determining the grasping position of the product to ensure the accuracy of subsequent assembly.

[0075] like Figure 12As shown, preferably, the product circulation mechanism includes a circulating conveyor belt, which comprises a parallel feeding belt 9 and a return belt 10. Both ends of the feeding belt 9 and the return belt 10 are connected by arc-shaped belts. Positioning installation stations are arranged on the feeding belt 9. The positioning module includes positioning cylinders 11 arranged on both sides of the feeding belt 9. Each positioning cylinder 11 has a positioning block that extends and retracts towards the positioning installation station. The blocking module includes a blocking cylinder 12 arranged on one side of the feeding belt 9. The lifting end of the blocking cylinder 12 is fixedly connected to a stop rod 13. The stop rod 13 is arranged above the feeding belt 9 to form a low-position blocking state or a high-position releasing state. The feeding belt 9 or the return belt 10 is sleeved on a rotating roller to form a loop-shaped tension state. One of the rotating rollers is driven by a conveyor motor. Starting the conveyor motor drives the rotating roller to rotate in a specific direction, and through friction, the feeding belt 9 or the return belt 10 circulates, thereby directionally conveying the product pallets placed on the top surface of the feeding belt 9 or the return belt 10. The aforementioned conveying structure is existing technology and common knowledge, therefore it will not be described in detail here. When the product pallet on the feeding belt 9 moves to the positioning and installation station, the stop cylinder 12 drives the stop lever 13 to descend and block the forward edge of the product pallet, thereby stopping the product pallet at the positioning and installation station. Four positioning cylinders 11 on both sides extend positioning blocks simultaneously, clamping and fixing the two sides of the product pallet through the positioning blocks, thereby stably positioning the product pallet to facilitate the subsequent precise insertion of accessories by the robot 7.

[0076] An assembly method for an automated system with dual-line feeding and integrated assembly includes the following steps:

[0077] A. Loading the WLAN card:

[0078] S1. Place a stack of WLAN card trays filled with WLAN cards on the two belts 103 of the feeding and conveying module 1. The two belts 103 move synchronously to transfer the stack of WLAN card trays to the lifting plate 305 of the lifting module 3. The lifting motor 301 of the lifting module 3 drives the servo transmission component to lift the lifting plate 305, lifting the stack of WLAN card trays to the top operating platform.

[0079] S2, X slide cylinder 402 drives the suction device 407 to move horizontally along the X direction, Y slide cylinder 404 drives the suction device 407 to move horizontally along the Y direction, Z slide cylinder 405 drives the suction device 407 to move up and down along the Z direction, rotary motor 406 drives the suction device 407 to rotate, the suction device 407 picks up the WLAN cards in the WLAN card tray one by one, the secondary positioning platform 5 rises, and the suction device 407 moves the WLAN cards onto the positioning fixture 503 of the secondary positioning platform 5;

[0080] S3. When all the WLAN cards in the WLAN card tray are emptied, the X-slide cylinder 402 drives the suction cup 411 to move along the X direction, so that the suction cup 411 moves above the empty WLAN card tray. The lifting motor 408 drives the suction cup 411 to descend, and the suction cup 411 picks up the empty WLAN card and transfers it to the empty tray placement position through the X-slide cylinder 402.

[0081] B. Loading wlan rubber:

[0082] S1. The feed roll 601 of the feeder 6 releases the material belt. The material belt passes through the edge of the peeling blade 605 and peels the wlan rubber on the material belt onto the unloading plate 606. The position of the wlan rubber on the unloading plate 606 is specifically sensed by the material sensor.

[0083] S2. The strip that has been stripped is taken in by take-up roll 602;

[0084] C. Dual-material assembly:

[0085] S1. Robot 7 moves to the secondary positioning platform 5 and picks up the Wlan card on the positioning fixture 503 through the suction picker 701. Then, robot 7 moves to the unloading plate 606 of feeder 6 and picks up wlan rubber through the clamping picker 702.

[0086] S2. Robot 7, carrying the WLAN card and WLAN rubber, moves above the lower vision positioning module 8 and uses the lower camera 802 to photograph the WLAN card and WLAN rubber to determine the fixed position of Robot 7 on the WLAN card and WLAN rubber.

[0087] S3, the feeding belt 9 transports the product pallet containing the workpiece to the positioning and installation station. The blocking module prevents the product pallet from moving forward, and the fixing module clamps and fixes the two sides of the product pallet. The workpiece has a first accessory station and a second accessory station.

[0088] S4. Robot 7 moves above the product tray. The upper vision positioning scanning module takes a picture of the first component station of the workpiece to determine the planar positioning of the first component station. The point laser height measuring instrument 703 measures the height of the first component station to determine the height positioning of the first component station. Because the product tray has a thickness error range, the height at which the workpiece is placed in each product tray is slightly different. The gripper 702 of robot 7 loads the WLAN rubber into the first component station.

[0089] Then, the upper vision positioning scanning module takes a picture of the second part station of the workpiece to determine the planar positioning of the second part station; the point laser height measuring instrument 703 measures the height of the second part station of the workpiece to determine the height positioning of the second part station; the suction picker 701 of the robot 7 inserts the WLAN card into the second part station; the upper vision positioning scanning module takes a picture of the WLAN card to scan the QR code on the WLAN card.

[0090] S5. After all the workpieces in the product tray have completed the accessory installation, the material fixing module resets and releases the product tray, the material blocking module lifts and releases the product tray, and the feeding belt 9 continues to transport the product tray forward.

[0091] The product pallet is transferred to the receiving position, the assembled products are taken out, and the empty product pallet is returned to the return belt 10, where unassembled workpieces are put back in, realizing the cyclical operation of the product pallet on the cyclical conveyor belt.

[0092] Preferably, the start-up of the pitch-adjusting motor 201 drives the lead screw 203 to rotate forward or reverse. The guide block 204 drives the rack 1 205 to move one side of the belt 103 outward or inward. The rack 1 205 synchronously drives the intermediate gear 206 to rotate. The intermediate gear 206 synchronously drives the rack 2 207 to move the other side of the belt 103 outward or inward, thus completing the adjustment operation of widening or narrowing the gap between the two belts 103.

[0093] When the size of the WLAN pallet is large, the two belts 103 are adjusted to widen the gap; when the size of the WLAN pallet is small, the two belts are adjusted to narrow the gap; thus, it can flexibly handle WLAN pallets of different specifications and expand the application range of multi-axis feeding machines.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
