DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0017] According to an embodiment of the present invention, a traceless hook production device is provided. Figure 2 and Fig.12 , comprising a work surface, a hook loading assembly 100 is arranged on the side of the work surface, a film loading assembly 200, a rotating disk 300, a glue coating assembly 400 and a curing assembly 500 are arranged above the work surface, the hook loading assembly 100 is arranged in parallel with the film loading assembly 200, the glue coating assembly 400 is located at the discharge end of the hook loading assembly 100, and the curing assembly 500 is located at the discharge end of the film loading assembly 200; The hook loading position is arranged at the hook loading component 100, the gluing position is arranged at the gluing component 400, the hook and film bonding position is arranged at the film loading component 200, the rotating disk 300 can be rotated and raised and lowered relative to the work table, and a plurality of manipulators 600 are evenly distributed along the circumference of the rotating disk 300. During the rotation of the rotating disk 300, the manipulators 600 reciprocate between the hook loading position, the gluing position and the hook and film bonding position.

[0018] It should be noted that by arranging the hook loading component 100, the film loading component 200, the rotating disk 300, the gluing component 400 and the curing component 500, the automated production of the traceless hook is realized and the production efficiency is improved; during the rotation of the rotating disk 300, the robot 600 reciprocates between the hook loading position, the gluing position and the hook and film bonding position to complete the operations of the hook from its loading position to the gluing position, the removal of the hook after gluing and the bonding with the film, etc. The structure is compact, the complexity of the equipment is reduced, and the space occupied is reduced.

[0019] In the traceless hook production device of this embodiment, please refer to Figures 2 to 5 The hook loading assembly 100 includes a vibrating screen plate 101 and a feeding track 102. The feeding track 102 is tilted, and its feeding end is located higher than its discharging end. The feeding end of the feeding track 102 is connected to the discharging end of the vibrating screen plate 101. A feeding slide is arranged inside the feeding track 102 for the hook to slide down under the action of its own gravity.

[0020] It should be noted that, by providing the downwardly inclined feeding track 102, unpowered transportation of the hook is achieved, thus saving energy.

[0021] In the traceless hook production device of this embodiment, please refer to Figures 1 to 5 The feeding track 102 includes an upper track 106, an auxiliary track 108 and a lower track 107 from top to bottom. The lower track 107 is provided with a lower groove 110 for accommodating the base end 4 of the hook, the upper track 106 is provided with an upper groove 109 for accommodating the hook body end 3 of the hook, and the auxiliary track 108 is provided with a through groove 111 for the hook body end 3 of the hook to pass through. The lower groove 110, the upper groove 109 and the through groove 111 together form the feeding slideway.

[0022] Specifically, the traceless hook includes a hook 1 and a film 2, wherein the hook 1 includes a base end 4 and a hook body end 3, the hook body end 3 is arc-shaped and is integrally formed with the base end 4, and the base end 4 is connected to the film 2.

[0023] It should be noted that when the hook 1 slides along the feeding slide, the base end 4 is limited inside the lower groove 110, and the hook body end 3 passes through the through groove 111 and extends to the upper groove 109, that is, the hook body end 3 is limited inside the upper groove 109; the through groove 111, the upper groove 109 and the lower groove 110 cooperate to ensure the directional and orderly transportation of the hook; the auxiliary track 108 is made of a low friction coefficient material, such as polytetrafluoroethylene, polyethylene, etc.

[0024] Specifically, the end of the through groove 111 close to the feeding end of the feeding track 102 is set to be rounded to avoid interference with the hook entering the feeding slideway.

[0025] In the traceless hook production device of this embodiment, please refer to Figures 2 to 5 A limiting track 103 is arranged at the discharge end of the feeding track 102, and a limiting slide connected to the feeding slide is arranged inside the limiting track 103. A limiting block 104 is symmetrically arranged above the limiting track 103. The symmetrically arranged limiting blocks 104 can move relatively to open or close the limiting slide, and the hook upper material position is set at the limiting slide.

[0026] It should be noted that the limit slide can accommodate a certain number of hooks at a time. By setting the limit block 104, the limit slide can be opened or closed, which makes it easier for the manipulator to grab the hooks in the limit slide and realize orderly feeding of the hooks. The entire feeding process does not require the participation of operators, thereby improving work efficiency.

[0027] During operation, the hook 1 is placed inside the vibrating screen plate 101. At this time, the hook 1 is in a disordered state. The vibration of the vibrating screen plate 101 drives the disordered hook 1 to be transported to the feeding track 102 in a single and directional manner. The hook 1 slides down to the limiting slide through the feeding slide under the action of its own gravity.

[0028] Specifically, the limiting slide is used to accommodate the base end 4 of the hook, and the symmetrically arranged limiting blocks 104 are close to each other to form a passage for the hook body end 3 of the hook to pass through. When the two limiting blocks 104 are relatively close to each other, a passage is formed for the hook body end 3 of the hook to pass through. At this time, the limiting slide is in a closed state, and the robot cannot clamp the hook; when the two limiting blocks 104 are relatively far away from each other, the limiting slide is in an open state, and the robot can clamp the hook.

[0029] It should be noted that the limit block 104 is slidably arranged above the limit track 103. At the same time, a fixed block 116 is arranged above the limit block 104. The fixed block 116 is connected to a driving element, and the driving element drives the fixed block 116 and the limit block 104 to move. Preferably, the driving element is a cylinder or an electric cylinder.

[0030] In the traceless hook production device of this embodiment, please refer to Figures 2 to 5 A blocking block 105 is provided at the connection point between the limiting slide and the feeding slide. The blocking block 105 can move in the vertical direction to apply a force to the hook body end 3 of the hook to prevent the hook 1 from being transported forward. It should be noted that after the number of hooks in the limiting slide reaches the single capacity, the blocking block 105 moves downward to apply force to the hook end 3, preventing the hook 1 from continuing to be transported forward; after the robot clamps the hook 1 in the limiting slide, the blocking block 105 moves upward to cancel the force applied to the hook end 3.

[0031] In the traceless hook production device of this embodiment, please refer to Figures 1 to 6 A spiral upward feeding track 117 is arranged on the inner wall of the vibrating screen plate 101, and a queuing track 118 for queuing the hooks 1 is connected to the end of the feeding track 117, and a screening plate 119 is arranged between the queuing track 118 and the feeding track 117 for allowing the hooks 1 to pass individually and in a directional manner, and the end of the queuing track 118 serves as the discharge end of the vibrating screen plate 101.

[0032] It should be noted that a loading plate 125 is provided at the outer edge of the end of the loading track 117 to prevent the hook 1 from falling. The loading plate 125 and the screening plate 119 are spaced apart to form a screening channel for a single hook 1 to pass through, and the screening channel only allows the hook to pass in a vertical posture (the lower surface of the base end 4 is in contact with the loading plate 125 or the screening plate 119); when the hooks entering the queuing track 118 continue to be transported forward, the hook body ends 3 of a part of the hooks are suspended on the hanging plate 126 at the outer edge of the queuing track 118, and the other part of the hooks 1 not suspended on the hanging plate 126 slides to the loading track 117 through the loading guide plate 120. There is a gap between the loading guide plate 120 and the loading plate 125 for the hook 1 to pass through. The hook 1 slides to the loading track 117 through the gap, and the hook suspended on the hanging plate 126 is transported to the feeding chute; a receiving plate 121 is provided on the periphery of the hanging plate 126 for receiving the hooks dropped from the hanging plate 126.

[0033] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 as well as Figures 7 to 11 The film loading assembly 200 includes a material storage tank 210, a grabbing assembly 220 and a film conveying unit 260. The grabbing assembly 220 grabs the film 2 located inside the material storage tank 210 and conveys the film 2 to the film conveying unit 260. The hook and the film bonding position are arranged at the film conveying unit 260. A film primary positioning unit 240 and a film secondary positioning unit 250 are arranged above the film conveying unit 260. The film primary positioning unit 240 is provided with a first channel for the film 2 to pass through, and the width of the first channel is adjustable. The film secondary positioning unit 250 is provided with a second channel corresponding to the first channel, and the width of the second channel is smaller than the width of the film 2.

[0034] It should be noted that the films 2 are closely arranged and stored in the storage trough 210. The grabbing assembly 220 grabs the films 2 from the discharge port of the storage trough 210 at a fixed frequency and places them in the film conveying unit 260. The film primary positioning unit 240 and the film secondary positioning unit 250 correct the position of the film 2 to avoid the film grabbing displacement phenomenon, improve the gluing alignment accuracy of the film 2 and the hook 1, and improve the production qualification rate of the traceless hook. The spacing of the first channel is adjustable, which can be adapted to correct the position of films of different specifications and sizes, thereby improving versatility. The film 2 is conveyed to the film secondary positioning unit for secondary position correction.

[0035] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 as well as Figures 7 to 9The film initial positioning unit 240 includes a first limiting plate 241 and a second limiting plate 242. The first limiting plate 241 and the second limiting plate 242 are spaced apart to form a first channel for the film 2 to pass through. The first limiting plate 241 is connected to the first guide plate 245, and the second limiting plate 242 is connected to the second guide plate 247. The first guide plate 245 and the second guide plate 247 are respectively connected to the output end of the bidirectional synchronous telescopic power element 244.

[0036] Specifically, the first limiting plate 241 and the second limiting plate 242 have the same structure. Taking the second limiting plate 242 as an example, the second limiting plate 242 includes a perpendicular transverse limiting edge 2421 and a longitudinal limiting edge 2422. The transverse limiting edge 2421 is arranged along a conveying direction parallel to the film 2, and the longitudinal limiting edge 2422 is arranged along a vertical direction. At the same time, a notch for the film 2 to pass through is arranged at the bottom of the longitudinal limiting edge 2422, and the longitudinal limiting edge 2422 is connected to the second guide plate 247; the notches on the first limiting plate 241 and the second limiting plate 242 jointly form a first channel.

[0037] It should be noted that the bidirectional synchronous telescopic power element 244 has two output ends, and the two output ends can move synchronously and in opposite directions, thereby driving the first limit plate 241 and the second limit plate 242 to move synchronously and in opposite directions to change the distance between the two; the first guide plate 245 is connected to one output end of the bidirectional synchronous telescopic power element 244 through the first connecting plate 246, and the second guide plate 247 is connected to the other output end of the bidirectional synchronous telescopic power element 244 through the second connecting plate 248.

[0038] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 as well as Figures 7 to 11 The film secondary positioning unit 250 includes two positioning rods 254 that are spaced apart, and a second channel corresponding to the first channel is formed between the two positioning rods 254, and the width of the second channel is smaller than the width of the film 2.

[0039] It should be noted that, under the action of the film conveying unit 260, when the film 2 is conveyed from the first channel to the second channel, the width of the second channel is smaller than the width of the film 2. Therefore, the positioning rod 254 temporarily blocks the film 2. Since the film conveying unit 260 continues to operate, the blocking effect of the positioning rod 254 can correct the skewed film 2 and further improve the gluing alignment accuracy of the film 2 and the hook 1.

[0040] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 as well as Figures 7 to 11The positioning rod 254 is connected to the first connecting rod 253 , the first connecting rod 253 is fixedly connected to one end of the swing rod 252 , and the other end of the swing rod 252 is hinged to the one-way telescopic power element 251 .

[0041] It should be noted that the top of the positioning rod 254 is connected to the first connecting rod 253 through the connecting block 255, and the first connecting rod 253 is rotatably connected to the work surface through the mounting bracket; the first connecting rod 253 is linked with the swing rod 252, and during the extension and retraction of the unidirectional telescopic power element 251 along the vertical direction, a force is applied to the first connecting rod 253 and the positioning rod 254 through the swing rod 252, so that the positioning rod 254 swings around the central axis of the first connecting rod 253; when the positioning rod 254 swings to the vertical position, it temporarily blocks the film 2 and performs a deviation correction operation; when the positioning rod 254 swings to the inclined position, its blocking effect on the film 2 disappears, and the film after deviation correction can continue to be transported forward.

[0042] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 as well as Figures 7 to 11 A support plate 270 is disposed between the upper and lower layers of the film conveying unit 260 , and a support groove 271 for accommodating the first limiting plate 241 , the second limiting plate 242 and the positioning rod 254 is disposed on the support plate 270 . It should be noted that the support groove 271 extends in parallel with the conveying direction of the film 2 to provide installation space for the first limiting plate 241 , the second limiting plate 242 and the positioning rod 254 .

[0043] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 and Figure 5 The material storage trough 210 is tilted and a material storage conveyor belt is arranged inside it. It should be noted that the storage trough 210 can be tilted downward by 10-20 degrees, preferably 15 degrees. Correspondingly, the storage conveyor belt is also tilted downward and consistent with the tilt angle of the storage trough 210. A certain tilt angle is conducive to the close arrangement of the film 2 under the compression of the compression block, and the compression block is located inside the storage trough 210. At the same time, a smaller tilt angle will not have a gripping effect on the grabbing assembly 220 at the discharge port.

[0044] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 and Figure 5 The grabbing assembly 220 includes a suction cup 221 connected to an external air circuit for controlling the suction and release of the film, and the suction cup 221 is provided with suction holes.

[0045] It should be noted that the grabbing assembly 220 is connected to a grabbing driving assembly 230 for driving the grabbing assembly 220 to reciprocate between the film conveying unit 260 and the discharge port of the storage trough 210, wherein the grabbing driving assembly 230 can adopt the existing technology and only needs to have the above-mentioned functions, which will not be repeated here, such as CN202120967832.6 A new type of film loading device.

[0046] In the traceless hook production device of this embodiment, please refer to Figure 2 , Fig.12 as well as Fig.13 The rotating disk 300 is rotatably arranged above the supporting frame 301, and the supporting frame 301 can be raised and lowered relative to the working table. A glue shielding plate 303 is arranged below the rotating disk 300, and the glue shielding plate 303 extends from the gluing position to the hook and film bonding position.

[0047] Specifically, the rotation driving element 302 is disposed inside the supporting frame 301 , and an output end of the rotation driving element 302 passes through the supporting frame 301 and is connected to the rotating disk 300 .

[0048] It should be noted that the rotating drive element 302 is arranged inside the supporting frame 301 to save installation space; after the rotating drive element 302 is started, it drives the rotating disk 300 to rotate relative to the supporting frame 301; the glue shielding plate 303 is used to receive the glue dripping from the hook after dipping.

[0049] In the traceless hook production device of this embodiment, please refer to Figure 2 , Fig.12 as well as Fig.13 The support frame 301 is connected to the end of the swing arm 304 , and a waist hole 305 extending along the vertical direction is provided at the connection between the two. The other end of the swing arm 304 is connected to the lifting drive element 306 .

[0050] It should be noted that a connecting shaft is provided between the top of the swing arm 304 and the waist hole 305. When the lifting drive element 306 drives the bottom of the swing arm 304 to rotate, under the cooperation of the connecting shaft and the waist hole 305, the swing arm 304 pulls the support frame 301 to rise and fall, thereby driving the manipulator 600 and the rotating disk 300 to rise and fall synchronously.

[0051] In the traceless hook production device of this embodiment, please refer to Figure 2 , Fig.12 as well as Fig.13 The rotating disk 300 is provided with manipulators 600 located on a plurality of different circles, and the plurality of circles are arranged concentrically.

[0052] It should be noted that, by arranging the manipulators 600 on a plurality of different circles, the needs of a plurality of traceless hook production lines can be met at the same time, thereby improving space utilization and production efficiency.

[0053] Specifically, the rotating disk 300 is provided with manipulators 600 located on two different circles, and the two circles are arranged concentrically, that is, one rotating disk 300 can meet the needs of two traceless hook production lines at the same time; four manipulators 600 are arranged on each circle, of which one manipulator 600 is an idle manipulator, and the other three manipulators 600 correspond to the hook loading position, the gluing position, and the hook and film bonding position respectively; two rotating disks 300 with the same structure are arranged on the work table, and the two rotating disks 300 can work independently or work in conjunction with the transmission shaft.

[0054] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 , Figures 14 to 19 The glue coating component 400 includes a glue storage tank 401 and a glue coating head 402. The glue coating head 402 is located inside the glue storage tank 401. The glue coating head 402 is linked with the manipulator 600 through a connecting rod unit. The movement directions of the glue coating head 402 and the manipulator 600 are opposite. The glue coating position is set at the glue storage tank 401. In the initial state, the glue coating head 402 is immersed in the glue, and in the ascending state, the glue coating head 402 is separated from the glue, and the glue coating head 402 is against the bottom surface of the base end 4 of the hook that descends synchronously with the robot 600.

[0055] It should be noted that by setting the gluing head 402 to be linked with the manipulator 600, and the moving directions of the gluing head 402 and the manipulator 600 are opposite, when the gluing head 402 rises, glue is applied to the bottom surface of the base end 4 of the hook that descends synchronously with the manipulator 600. At this time, the hook 1 reaches the gluing position; when the gluing head 402 descends, the hook 1 rises synchronously with the manipulator 600, thereby realizing the mechanization of gluing the hook 1, improving work efficiency, eliminating the need for manual intervention, and avoiding harm to the operator's body caused by glue; the amount of glue applied is controlled by the contact time between the gluing head 402 and the bottom surface of the base end 4 and the rising displacement of the gluing head 402, so the amount of glue applied and the product quality can be accurately controlled.

[0056] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 , Figures 14 to 19 A clearance groove 407 is provided at the bottom of the glue storage tank 401, a first end of the third connecting plate 403 passes through the clearance groove 407 and is connected to the glue coating head 402, and a second end of the third connecting plate 403 is connected to the connecting rod unit.

[0057] It should be noted that, driven by the connecting rod unit, the third connecting plate 403 is lifted and lowered inside the clearance groove 407 , and at the same time, the third connecting plate 403 drives the glue coating head 402 to lift and lower.

[0058] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 , Figures 14 to 19 The connecting rod unit includes a first connecting rod 404 and a second connecting rod 405 arranged along the vertical direction. The bottom end of the first connecting rod 404 and the top end of the second connecting rod 405 are rotatably connected to the two ends of the second connecting rod 406 respectively. The top end of the first connecting rod 404 is connected to the supporting frame 301, and the bottom end of the second connecting rod 405 is connected to the glue coating head 402 through the third connecting plate 403. The middle part of the second connecting rod 406 is rotatably connected to the glue storage tank 401.

[0059] It should be noted that the middle part of the second connecting rod 406 is rotatably connected to the glue storage tank 401, so that the two ends of the second connecting rod 406 form a lever structure. In addition, the first connecting rod 404 and the second connecting rod 405 are both arranged vertically, that is, the first connecting rod 404 and the second connecting rod 405 are respectively located at the two ends of the lever structure, and the top of the first connecting rod 404 is linked with the support frame 301. When the lifting drive element 306 drives the bottom of the swing arm 304 to rotate, under the cooperation of the connecting shaft and the waist hole 305, the swing arm 304 pulls the support frame The frame 301 is raised and lowered, thereby driving the manipulator 600, the rotating disk 300, and the first connecting rod 404 to rise synchronously, and the second connecting rod 405 rises synchronously, thereby driving the third connecting plate 403 and the gluing head 402 to rise, so that the gluing head 402 moves in the opposite direction to the manipulator 600; the manipulator 600 clamps the hook 1 and descends, and at the same time, the gluing head 402 rises, so that the gluing head 402 abuts against the bottom surface of the base end 4 of the hook that descends synchronously with the manipulator 600, and glue is applied, and the gluing position is the position where the gluing head 402 abuts against the bottom surface of the base end 4. A fixed plate 408 is arranged below the glue storage tank 401, and the third connecting plate 403 is connected to the fixed plate 408 through a sliding guide assembly.

[0060] In the traceless hook production device of this embodiment, please refer to Figure 1 , Figure 2 , Figures 14 to 19 The glue coating head 402 is provided with a sponge for absorbing glue.

[0061] It should be noted that, in the initial state, the glue coating head 402 is immersed in glue, and glue is adsorbed on the surface and inside of the sponge. When the glue coating head 402 is against the bottom surface of the base end 4 of the hook that descends synchronously with the manipulator 600, the glue on the surface and inside of the sponge is squeezed and coated on the bottom surface of the base end 4; when the glue coating head 402 is against the bottom surface of the base end 4 of the hook that descends synchronously with the manipulator 600, the bottom surface of the base end 4 does not enter the glue inside the glue storage tank 401.

[0062] In the traceless hook production device of this embodiment, please refer to Figures 1 to 19 The curing assembly 500 includes a curing chamber and a curing conveying unit. The curing conveying unit runs through the curing chamber and is transmission-connected to the film conveying unit 260. Ultraviolet curing lamps are provided inside the curing chamber and at the hook and film bonding position.

[0063] It should be noted that the robot 600 clamps the hook 1 at the hook loading position, and as the rotating disk 300 rotates and descends, the robot 600 moves the clamped hook to the gluing position for gluing. After the gluing is completed, as the rotating disk 300 rises and rotates, the robot 600 moves the clamped hook to the hook and film bonding position, and bonds the glued hook with the film 2 at the hook and film bonding position, and at the same time, performs the initial curing; the film conveying unit 260 and the curing conveying unit are on the same horizontal plane, and after the hook and the film are bonded, they are conveyed to the curing chamber via the film conveying unit 260 and the curing conveying unit for secondary curing, and finally a traceless hook is formed.

[0064] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
