Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically a fully automatic wrapping and core-threading machine. Background Technology

[0002] In some precision electronic products, it is necessary to use conductive cloth to wrap structural components such as foam core strips. In the existing processing methods, the conductive cloth and foam core strips are processed separately. The conductive cloth is rolled up in pieces on the material strip, while the foam core strips are cut into individual segments and then manually assembled using jigs. Obviously, this assembly method is inefficient, and because some components are small in size, manual assembly is more troublesome and prone to defects such as unstable product quality. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a fully automatic wrapping and core-threading machine that can automatically assemble conductive fabric and foam core strips for already generated and rolled conductive fabric tape and foam core strip units.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic wrapping and core-threading machine for wrapping conductive cloth around a foam core material. The fully automatic wrapping and core-threading machine includes a frame, on which are respectively provided:

[0005] Feeder stripping mechanism: It peels the conductive cloth individual units from the conductive cloth roll and sends them to its stripping table. The feeder stripping mechanism is a step-by-step operation, that is, it automatically stops after peeling off a set of conductive cloth individual units, and peels off the next set after the conductive cloth individual units are taken away.

[0006] Conductive cloth flipping mechanism: After the conductive cloth unit located on the peeling table of the feeder peeling mechanism is picked up and removed from the peeling table, it is flipped so that the conductive cloth unit is turned up.

[0007] Conductive cloth feeding mechanism: It includes a rotatable feeding base and at least one set of conductive cloth positioning fixtures disposed thereon. The conductive cloth positioning fixtures are provided with a through-hole relief groove, and the fixture surfaces on both sides of the relief groove are provided with adsorption holes. The conductive cloth feeding mechanism is also provided with a lifting cylinder for driving the conductive cloth positioning fixtures to rise and fall.

[0008] Conductive cloth positioning and transfer robot: It contains a CCD vision positioning system, which automatically identifies the angle of the conductive cloth unit and performs angle compensation accordingly, and positions and transfers the conductive cloth unit from the conductive cloth flipping mechanism to the conductive cloth positioning fixture of the conductive cloth feeding mechanism.

[0009] Foam core strip feeding mechanism: It includes a core strip guide plate set on the frame, a core strip positioning groove on the core strip guide plate, and the core strip positioning groove is connected to an external vibrating feeder, so that the foam core strips are automatically positioned in the core strip positioning groove one by one for transfer;

[0010] Package core-piercing mechanism: The package core-piercing mechanism has a horizontal support plate. At least one accommodation and limiting groove for accommodating the foam core strip is provided on the horizontal support plate. Both ends of the accommodation and limiting groove have through first through holes, and a core strip push rod that can penetrate the first through holes is provided in the accommodation and limiting groove. The outer end of the core strip push rod is connected to a core strip push rod drive assembly and reciprocates along both ends of the accommodation and limiting groove under its drive. The push rod drive assembly also synchronously drives a shaping core shaft that is coaxially arranged and spaced relatively to the core strip push rod; a package core-piercing station is formed between the core strip push rod and the shaping core shaft; on both sides of the package core-piercing station, there are package shoveling plates and shoveling plate drive assemblies; when the shaping core shaft runs to the conductive cloth positioning fixture at the package core-piercing station and cooperates with the lifting cylinder that drives the conductive cloth positioning fixture to lift, it bends the conductive cloth so that both sides of the conductive cloth are翘起 (the specific Chinese character here seems incorrect, assuming it should be something like "翘 up"), and the package shoveling plate presses and folds the翘起 edges (again, the incorrect Chinese needs to be corrected); the core strip push rod pushes the foam core strip located in the accommodation and limiting groove into the conductive cloth tube after package shaping through the first through hole, and at the same time, the shaping core shaft disengages from the conductive cloth tube;

[0011] Foam core strip transfer mechanism: It includes an adsorption type transfer adsorption head and an adsorption head drive assembly, which transfers the foam core strip from the core strip positioning groove of the feeding mechanism to the accommodation and limiting groove of the package core-piercing mechanism;

[0012] Hot pressing mechanism: It has a vertically liftable hot pressing component. The hot pressing component is located directly above the package core-piercing station and is aligned with the avoidance through groove on the conductive cloth positioning fixture conveyed by the conductive cloth feeding mechanism; after the package shoveling plate on the package core-piercing mechanism presses and folds the conductive cloth, the hot pressing component descends under the drive of the hot pressing component drive part, pressing the overlapped conductive cloth edges between the shaping core shafts to achieve shaping and packaging;

[0013] Unloading mechanism: It is arranged above the conductive cloth loading and unloading station of the conductive cloth feeding mechanism and removes the finished product after package core-piercing from the conductive cloth positioning fixture;

[0014] The conductive cloth positioning fixture switches between the package core-piercing station and the conductive cloth loading and unloading station under the drive of the rotatable loading base; after the conductive cloth unloading mechanism removes the product after package core-piercing, the conductive cloth positioning transfer manipulator then transfers the single conductive cloth to the conductive cloth positioning fixture;

[0015] Specifically, in the above-mentioned fully automatic package core-piercing machine, a "convex" - shaped hollow part is formed on the horizontal support plate of the package core-piercing mechanism. On both upper corner areas on both sides of the "convex" - shaped hollow part on the horizontal support plate, an accommodation and limiting groove is respectively formed. Both ends of the accommodation and limiting groove are respectively provided with coaxial first through holes that are communicated with the outside and the "convex" - shaped hollow part. On the bottom horizontal bar of the "convex" - shaped hollow part on the horizontal support plate, a second through hole that is coaxial with the first through hole is also provided. The shaping core shaft can shuttle through the second through hole and enter and exit the "convex" - shaped hollow part; It should be noted that there are some unclear or incorrect Chinese characters in the original text which may affect the accurate understanding and translation. The translation is based on the best interpretation of the text as it is.

[0016] Inside the "convex"-shaped hollow part, there is a pair of inwardly-facing inner wrapping shovel plates arranged back-to-back. On the two outer sides of the "convex"-shaped hollow part, there is a pair of outwardly-facing outer wrapping shovel plates arranged oppositely. The inwardly-facing inner wrapping shovel plates and the outwardly-facing outer wrapping shovel plates together form a set of wrapping shovel plates for pressing and folding the edge of the conductive cloth.

[0017] On both sides of the horizontal support plate, there are also avoidance concave parts for avoiding the outer wrapping shovel plates. The wrapping shovel plates are in an "L"-shaped configuration arranged oppositely and are respectively connected to the shovel plate driving components; each set of shovel plate driving components synchronously drives the inner wrapping shovel plate and the outer wrapping shovel plate in a set of wrapping shovel plates to move towards each other.

[0018] At both ends of the rotatable loading base of the conductive cloth loading mechanism, two conductive cloth positioning fixtures are respectively installed, that is, one conductive cloth positioning fixture is provided at each of the four corners of the rotatable loading base; the lifting cylinder is installed below the rotatable loading base and drives the entire rotatable loading base to rise and fall, thereby driving the conductive cloth positioning fixtures to rise and fall; the rotatable loading base is driven by a cylinder located below it to rotate reciprocally, so that the two sets of conductive cloth positioning fixtures reciprocally switch between the conductive cloth loading and unloading station and the wrapping through-core station;

[0019] The conductive cloth flipping mechanism is installed in front of the end side of the feeder stripping mechanism. It includes a first liftable support component, a flipping arm installed on the first liftable support component, a flipping motor installed on the first liftable support component and driving the flipping arm, and conductive cloth suction heads symmetrically installed at both ends of the flipping arm with respect to the flipping axis. The conductive cloth suction head at one end faces downward and is directly above the stripping table surface of the feeder stripping mechanism; the flipping angle of the flipping arm each time is 180°; the flipping arm descends from a high position under the drive of the first liftable support component, so that the conductive cloth suction head at one end contacts and adsorbs the conductive cloth on the stripping table surface, and then the flipping arm rises to a high position under the drive of the first liftable support component. At this time, there is enough space for the flipping arm to flip 180°. At this time, the conductive cloth suction head adsorbed with the conductive cloth faces upward, waiting for the conductive cloth transfer manipulator to transfer the conductive cloth, while the conductive cloth suction head at the other end faces downward and is directly opposite the stripping table surface, waiting for the next conductive cloth suction operation;

[0020] The foam core strip transfer mechanism is located between the foam core strip feeding mechanism and the core wrapping and threading mechanism. The foam core strip transfer mechanism includes a longitudinal support assembly, a first transverse moving support assembly mounted on the longitudinal support assembly, two downward-facing longitudinal core strip transfer cylinders mounted on the first transverse moving support assembly, and core strip suction heads respectively mounted on the output ends of the longitudinal core strip transfer cylinders. The positional distance between the two core strip suction heads is approximately equal to the positional distance between the two core strip positioning slots of the foam core strip feeding mechanism. The first transverse moving support assembly drives two sets of core strips... The strip adsorption head moves to the top of the core strip positioning groove. Then, the longitudinal core strip transfer cylinder moves downward to drive the core strip adsorption head to contact and adsorb the foam core strip. Then, the output end of the longitudinal core strip transfer cylinder rises and resets. The core strip adsorption head sucks the foam core strip away from the core strip positioning groove. Then, driven by the first transverse moving bracket assembly, the whole thing moves towards the receiving and limiting groove of the core wrapping mechanism. After it is in place, the output end of the longitudinal core strip transfer cylinder moves downward to place the foam core strip on the core strip adsorption head into the receiving and limiting groove. After adsorption stops, it rises and resets, waiting for the next core strip transfer operation.

[0021] The hot-pressing mechanism includes a hot-pressing support assembly spanning above the core-piercing station, two hot-pressing component drive units mounted on the hot-pressing support assembly, and hot-pressing components connected to the output ends of the hot-pressing component drive units. Each hot-pressing component consists of a heating element, a heat-conducting block, etc. After the lower wrapping spatula finishes pressing down the raised edge of the conductive fabric, the two sets of hot-pressing components quickly descend to press down on the conductive fabric, causing the adhesive surface of the conductive fabric to heat-melt and bond together, forming a conductive fabric tube. After wrapping is completed, the hot-pressing components rise and reset.

[0022] The unloading mechanism is located at the conductive cloth loading / unloading station of the conductive cloth loading mechanism. The unloading mechanism includes a second liftable support assembly, a second transverse moving support assembly mounted on the second liftable support assembly, and two unloading gripper assemblies suspended on the second transverse moving support assembly. The unloading gripper assembly includes a gripper bracket, a gripper drive cylinder, and two grippers. When the grippers are in the open state, they descend to a position lower than the finished product, with both ends of the grippers located below the finished product. Then, the two grippers shorten the distance between them, so that both ends of the finished product are gently clamped on the grippers. The finished product is then lifted and transferred away from the conductive cloth positioning fixture by the second liftable support assembly and the second transverse moving support assembly, and transferred to the moving receiving box or unloading conveyor belt.

[0023] The fully automatic wrapping and core-threading machine is equipped with a set of feeder stripping mechanisms, a set of conductive cloth flipping mechanisms, and a set of conductive cloth transfer robots. Correspondingly, it has two sets of foam core feeding mechanisms, two sets of core transfer mechanisms, two sets of wrapping and core-threading mechanisms, two sets of conductive cloth feeding mechanisms, two sets of hot-pressing mechanisms, and two sets of unloading mechanisms. One operating cycle can produce four finished wrapped and core-threaded components.

[0024] This invention relates to a fully automated wrapping and core-threading machine designed for the automatic assembly of conductive fabric rolls and foam core strips. It achieves automatic material feeding through a feeder peeling mechanism and a vibrating feeder; automatic transfer and feeding of the conductive fabric through a conductive fabric flipping mechanism, a conductive fabric transfer robot, and a conductive fabric loading mechanism; automatic transfer and feeding of the foam core strips through a foam core strip transfer mechanism; automatic wrapping and core-threading through a wrapping and core-threading mechanism; and automatic unloading through a feeding mechanism. This achieves fully automated wrapping and core-threading operations, completing the assembly of the conductive fabric wrapped and core-threaded assembly. Therefore, this invention significantly improves assembly efficiency and quality while reducing product production costs. Attached Figure Description

[0035] Please see the appendix Figure 1 , Figure 2 , Figure 3As shown, the present invention discloses a fully automatic wrapping and core-threading machine for wrapping conductive cloth around a foam core material. The fully automatic wrapping and core-threading machine includes a frame 1, on which are respectively provided:

[0036] Feeder stripping mechanism 2: peels the conductive cloth individual units from the conductive cloth roll and sends them to its stripping table. Feeder stripping mechanism 2 is a step-by-step operation, that is, it automatically stops after peeling off a set of conductive cloth individual units, and peels off the next set after the conductive cloth individual units are taken away.

[0037] Conductive cloth flipping mechanism 3: After the conductive cloth unit located on the peeling table of feeder peeling mechanism 2 is picked up and removed from the peeling table, it is flipped so that the conductive cloth unit is turned up.

[0038] The conductive cloth feeding mechanism 4 includes a rotatable feeding base 41 and at least one set of conductive cloth positioning fixtures 42 disposed thereon. The conductive cloth positioning fixture 42 is provided with a through-hole relief groove 421. The fixture surface on both sides of the relief groove 421 is provided with adsorption holes to adsorb the conductive cloth and achieve a positioning effect. The conductive cloth feeding mechanism 4 is also provided with a lifting cylinder 43 for driving the conductive cloth positioning fixture 42 to rise and fall.

[0039] Conductive cloth positioning and transfer robot 5: It contains a CCD vision positioning system, which automatically identifies the angle of the conductive cloth unit and performs angle compensation accordingly, and positions and transfers the conductive cloth unit from the conductive cloth flipping mechanism 3 to the conductive cloth positioning fixture 42 of the conductive cloth feeding mechanism 4.

[0041] The core-threading mechanism 7 includes a horizontal support plate 71 with at least one receiving and limiting groove 711 for accommodating foam core strips. Both ends of the receiving and limiting groove 711 have through first holes 712, and a core strip push rod 72 that can pass through the first through holes 712 is provided within the receiving and limiting groove 711. The outer end of the core strip push rod 72 is connected to a core strip push rod drive assembly 73, which drives the push rod to reciprocate along both ends of the receiving and limiting groove 711. The push rod drive assembly 73 also synchronously drives a shaping mandrel 74 that is coaxially arranged and spaced relative to the core strip push rod 72. The position between the core strip pusher 72 and the shaping mandrel 74 forms a wrapping and core-piercing station 700; the wrapping and core-piercing station 700 is provided with wrapping shovels 75 and shovel drive assemblies 76 on both sides; the shaping mandrel 74, in cooperation with the conductive cloth positioning fixture 42 and the lifting cylinder 43 running to the wrapping and core-piercing station 700, bends the conductive cloth so that the two sides of the conductive cloth are raised, and the wrapping shovels 75 presses and wraps the raised edges; the core strip pusher 72 then pushes the foam core strip located in the receiving and limiting groove 711 from the first through hole 712 into the wrapped and shaped conductive cloth tube, while the shaping mandrel 74 disengages from the conductive cloth tube;

[0042] Foam core strip transfer mechanism 8: includes core strip adsorption head 81 and adsorption head drive assembly 82, which transfers foam core strip from the core strip positioning groove 611 of the feeding mechanism to the receiving and limiting groove 711 of the wrapping and core-threading mechanism 7;

[0043] Hot pressing mechanism 9: It has a hot pressing component 91 that can be raised and lowered longitudinally. The hot pressing component 91 is located directly above the core-threading station 700 and is directly opposite to the clearance groove 421 on the conductive cloth positioning fixture 42 conveyed by the conductive cloth feeding mechanism 4. When the wrapping spatula 75 on the core-threading mechanism 7 presses and folds the conductive cloth, the hot pressing component 91 is lowered under the drive of the hot pressing component driving component 92, pressing the edge of the stacked conductive cloth between the shaping mandrels 74 to achieve shaping and wrapping.

[0044] Feeding mechanism 10: Located above the conductive cloth feeding station 400 of the conductive cloth feeding mechanism 4, it removes the finished product with the core wrapped from the conductive cloth positioning fixture.

[0045] Driven by the rotatable feeding base 41, the conductive cloth positioning fixture 42 switches between the wrapping and core-piercing station 700 and the conductive cloth unloading and loading station 400. After the conductive cloth unloading mechanism 10 removes the wrapped and core-pierced product, the conductive cloth positioning and transfer robot 5 transfers the conductive cloth unit to the conductive cloth positioning fixture.

[0046] Specifically, combined Figure 4As shown in the figure, in the above-mentioned fully automatic package core-piercing machine, a "convex"-shaped hollow part 710 is formed on the horizontal support plate 71 of the package core-piercing mechanism 7. On both upper corner regions of the "convex"-shaped hollow part 710 on the horizontal support plate 71, a receiving limit groove 711 is formed respectively. At both ends of the receiving limit groove 711, first through holes 712 with the same axis and communicating with the outside and the "convex"-shaped hollow part 710 are respectively opened. A through-type core bar push rod 72 is穿设 in each receiving limit groove 711, and the outer end of the core bar push rod 72 is connected to a push rod driving component 73; the push rod driving component 73 also synchronously drives a shaping core shaft 74 arranged coaxially and at intervals relative to the core bar push rod 72. A second through hole 7101 with the same axis as the first through hole 712 is also opened on the bottom horizontal bar of the "convex"-shaped hollow part 710 on the horizontal support plate 71, and the shaping core shaft 74 can shuttle through the second through hole 7101 and enter and exit the "convex"-shaped hollow part 710;

[0047] Inside the "convex"-shaped hollow part 710, a pair of inwardly facing inner package shovel plates 751 are provided, and on both outer sides of the "convex"-shaped hollow part 710, a pair of outwardly facing outer package shovel plates 752 are provided. The inwardly facing inner package shovel plates 751 and the outwardly facing outer package shovel plates 752 together form a package shovel plate 75 for pressing and folding the edge of the conductive cloth;

[0048] In order to avoid interference with the two groups of package shovel plates 75, avoidance recesses are provided on both sides of the horizontal support plate 71. The package shovel plates 75 are also designed in a relative "L" shape and are respectively connected to a shovel plate driving component 76; each group of shovel plate driving components 76 synchronously drives the inner package shovel plate 751 and the outer package shovel plate 752 in a group of package shovel plates 75 to move towards each other.

[0049] Combined with Figure 5 As shown in the figure, two conductive cloth positioning fixtures 42 are respectively installed at both ends of the rotatable loading base 41 of the conductive cloth loading mechanism 4, that is, one conductive cloth positioning fixture 42 is provided at each of the four corners of the rotatable loading base 41; the lifting cylinder 43 is installed below the rotatable loading base 41 and drives the entire rotatable loading base 41 to lift, thereby driving the conductive cloth positioning fixture to lift; (or each conductive cloth positioning fixture 42 can be separately equipped with a lifting cylinder for driving its lifting); the rotatable loading base 41 is driven by a rotation driving component 411 located below it to rotate reciprocally, so that the two groups of conductive cloth positioning fixtures 42 reciprocally switch between the conductive cloth loading and unloading station 400 and the package core-piercing station 700;

[0050] Combined with Figure 6As shown, the conductive cloth flipping mechanism 3 is installed at the front end of the feeder stripping mechanism 2. It includes a first liftable support assembly 31, a flipping arm 32 mounted on the first liftable support assembly 31, a flipping motor 33 mounted on the first liftable support assembly 31 and driving the flipping arm 32, and conductive cloth suction heads 34 centrally symmetrically mounted at both ends of the flipping arm 32 relative to the flipping axis. One end of the conductive cloth suction head 34 faces downwards and is located directly above the stripping table of the feeder stripping mechanism 2. The flipping angle of the flipping arm 32 is 180° each time. The rotating arm 32 descends from a high position under the drive of the first lifting bracket assembly 31, so that the conductive cloth adsorption head 34 at one end contacts and adsorbs the conductive cloth on the stripping table. Then, the rotating arm 32 rises to a high position under the drive of the first lifting bracket assembly 31. At this time, there is enough space for the rotating arm 32 to rotate 180°. At this time, the conductive cloth adsorption head 34 with the conductive cloth adsorbed faces upward, waiting for the conductive cloth positioning and transfer robot 5 to transfer the conductive cloth, while the conductive cloth adsorption head at the other end faces downward and faces the stripping table, waiting for the next conductive cloth suction operation.

[0051] Combination Figure 7 As shown, the foam core strip transfer mechanism 8 is located between the foam core strip feeding mechanism 6 and the wrapping and core-threading mechanism 7; the foam core strip transfer mechanism 8 includes a longitudinal support assembly 821, a first transverse moving support assembly 822 mounted on the longitudinal support assembly 821, two vertical core strip transfer cylinders 823 with their output ends facing downwards mounted on the first transverse moving support assembly 822, and core strip suction heads 81 respectively mounted on the output ends of the vertical core strip transfer cylinders 823. The positional distance between the two core strip suction heads 81 is approximately equal to the positional distance between the two core strip positioning slots 611 of the foam core strip feeding mechanism 6; the first transverse moving support assembly 822 drives the two The core strip adsorption head 81 moves to the top of the core strip positioning groove 611. Then, the longitudinal core strip transfer cylinder 823 moves downward to drive the core strip adsorption head 81 to contact and adsorb the foam core strip. Then, the output end of the longitudinal core strip transfer cylinder 823 rises and resets. The core strip adsorption head 81 sucks the foam core strip away from the core strip positioning groove 611. Then, driven by the first transverse moving bracket assembly 822, the whole thing moves towards the receiving and limiting groove 711 of the core wrapping mechanism 7. After it is in place, the output end of the longitudinal core strip transfer cylinder 823 moves downward to place the foam core strip on the core strip adsorption head 81 into the receiving and limiting groove 711. After adsorption stops, it rises and resets, waiting for the next core strip transfer operation.

The hot-pressing components 91 are composed of heating tubes, heat-conducting blocks, etc. After the lower wrapping spatula 75 finishes pressing down the raised edge of the conductive cloth, the two sets of hot-pressing components 91 quickly descend to press down on the conductive cloth, causing the adhesive surface of the conductive cloth to melt and bond together, forming a conductive cloth tube. After wrapping is completed, the hot-pressing components 91 rise and return to their original position.

[0053] Combination Figure 9 As shown, the unloading mechanism 10 is located at the conductive cloth loading / unloading station 400 of the conductive cloth loading mechanism 4; the unloading mechanism 10 includes a second liftable support assembly 101, a second transverse moving support assembly 102 mounted on the second liftable support assembly 101, and two unloading gripper assemblies 103 suspended on the second transverse moving support assembly 102; the unloading gripper assembly 103 includes a gripper bracket 1031, a gripper drive cylinder 1032, and two grippers 1033. When the grippers 1033 are in the open state, they descend to a position lower than the finished product, with both ends of the grippers 1033 located below the finished product. Then, the two grippers 1033 are brought together at a certain distance, so that both ends of the finished product are gently clamped on the grippers 1033. Then, the finished product is lifted and transferred away from the conductive cloth positioning fixture 42 by the second liftable support assembly 101 and the second transverse moving support assembly 102, and transferred to the moving receiving box or unloading conveyor belt.

[0054] In this embodiment, the frame 1 of the fully automatic wrapping and core-threading machine is equipped with a set of feeder stripping mechanisms 2, a set of conductive cloth flipping mechanisms 3, and a set of conductive cloth positioning and transfer manipulators 5. Correspondingly, it is equipped with two sets of foam core strip feeding mechanisms 6, two sets of foam core strip transfer mechanisms 8, two sets of wrapping and core-threading mechanisms 7, two sets of conductive cloth feeding mechanisms 4, two sets of hot-pressing mechanisms 9, and two sets of unloading mechanisms 10. One operating cycle can produce four finished wrapped and core-threaded components.

[0055] In this embodiment, the wrapping and core-threading mechanism 7 is equipped with two sets of accommodating and limiting grooves 711, two sets of core strip push rods 72 and shaping mandrels 74, and two sets of wrapping spatulas 75. It is also equipped with two sets of hot pressing components 91 and two core strip adsorption heads 81. Each operation can complete the wrapping and core-threading of two conductive fabric foam core strips at the same time.

[0056] The working process of this invention is as follows:

[0057] First, the feeder stripping mechanism 2 of the conductive cloth performs the conductive cloth stripping operation, and the foam core strips also run one by one into the core strip positioning groove 611 of the foam core strip feeding mechanism 6 under the action of the vibrating feeder.

[0058] Then, the conductive cloth flipping mechanism 3 picks up the conductive cloth unit located on the stripping table of the feeder stripping mechanism 2, flips it 180°, so that the conductive cloth unit flips over and leaves the stripping table. Then, the conductive cloth positioning and transfer robot 5 picks up the conductive cloth that has been flipped 180° and transfers it to the conductive cloth positioning fixture 42 of the conductive cloth feeding mechanism 4. In this embodiment, one conductive cloth positioning and transfer robot 5 performs the conductive cloth transfer operation. In one cycle, four conductive cloth units are transferred and placed into four conductive cloth positioning fixtures 42 of the two sets of conductive cloth feeding mechanisms 4.

[0059] On the other hand, the two core strip adsorption heads 81 of the foam core strip transfer mechanism 8 transfer the foam core strip from the core strip positioning groove 611 to the receiving and limiting groove 711 of the wrapping core threading mechanism 7;

[0060] Then, the rotatable feeding base 41 of the conductive cloth feeding mechanism 4 rotates 180 degrees, so that the conductive cloth positioning fixture 42, which holds the conductive cloth unit, is located below the wrapping and core-piercing station 700.

[0061] At this time, in the core-threading mechanism 7, the inner end of the core strip push rod 72 is located in the first through hole 712 near the outer end. The foam core strip transferred by the foam core strip transfer mechanism 8 is placed in the accommodating limiting groove 711, and the foam core strip is limited and aligned with the first through hole 712 in the same direction. The shaping mandrel 74 is inserted into the second through hole 7101 and suspended in the "convex" shaped hollow part 710. At this time, the avoidance groove 421 on the conductive cloth positioning fixture 42 of the conductive cloth feeding mechanism 4 located below, the conductive cloth unit and the shaping mandrel 74 are aligned. The conductive cloth positioning fixture 42 rises vertically under the drive of its lifting cylinder 43. With the cooperation of the shaping mandrel 74, the middle part of the conductive cloth unit is pressed into the avoidance groove 421 and the two sides are raised. Then the wrapping shovels located above the two sides of the shaping mandrel 74 The plate 75 presses and wraps the conductive cloth that is raised on both sides towards the upper surface of the shaping mandrel 74. Then, the hot pressing component 91 of the hot pressing mechanism 9 presses down on the conductive cloth and heats and fuses it, so that the two sides of the conductive cloth are bonded together, thus achieving the wrapping of the conductive cloth. After the wrapping is completed, the push rod drive component 73 drives the core strip push rod 72 and the shaping mandrel 71 to move simultaneously. On one hand, the core strip push rod 72 pushes the foam core strip placed in the receiving and limiting groove 711 through the first through hole 712 into the just wrapped and shaped conductive cloth tube. At the same time, the shaping mandrel 74 exits the conductive cloth tube. The two ends of the conductive cloth tube are stopped by the limiting of the inner wall of the "convex" shaped hollow part 710 until the foam core strip is completely separated from the receiving and limiting groove 711 and the first through hole 712, and the shaping mandrel 74 is completely separated from the conductive cloth tube, thus completing the core insertion operation.

[0062] Then, the lifting cylinder 43 of the conductive cloth feeding mechanism 4 falls, causing the conductive cloth positioning fixture 42 to fall. Then, driven by the rotatable feeding base 41, it rotates 180 degrees. On the one hand, the wrapped and cored product leaves the wrapping and cored station 700 and is removed by the conductive cloth unloading mechanism 10. On the other hand, the conductive cloth to be wrapped on the conductive cloth positioning fixture 42 at the other end of the rotatable feeding base 41 enters the wrapping and cored station 700. Driven by its lifting cylinder 43, it cooperates with the shaping mandrel 74, hot pressing mechanism 9, etc. to carry out the wrapping operation.

[0063] This operation enables automatic feeding, transfer, wrapping, core insertion, and unloading of conductive cloth and foam core strips.

[0064] In this invention, the feeder stripping mechanism 2, the vibrating feeder 62, and the conductive cloth positioning and transfer robot 5 are all existing technologies, and their specific structures will not be described in detail. In addition, the frame of the fully automatic wrapping and core-threading machine is also equipped with a control module, a touch screen display, and other devices, which can be configured as needed, and therefore will not be described in detail either.

[0065] This invention relates to a fully automated wrapping and core-threading machine designed for the automatic assembly of conductive fabric rolls and foam core strips. It achieves automatic material feeding through a feeder peeling mechanism and a vibrating feeder; automatic transfer and feeding of the conductive fabric through a conductive fabric flipping mechanism, a conductive fabric positioning and transfer robot, and a conductive fabric loading mechanism; automatic transfer and feeding of the foam core strips through a foam core strip transfer mechanism; automatic wrapping and core-threading through a wrapping and core-threading mechanism; and automatic unloading through a feeding mechanism. This achieves fully automated wrapping and core-threading operations, completing the assembly of the conductive fabric wrapped and core-threaded assembly. Therefore, this invention significantly improves assembly efficiency and quality while reducing product production costs.
