[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present application embodiment discloses a fully automatic plastic hook bonding machine. Figure 1 , Figure 2 and Figure 3The fully automatic plastic hook bonding machine includes an operating table, a feeding mechanism for conveying the hook body and the bottom film to the operating table, and a glue dispensing mechanism 6 for dripping adhesive on the bottom film. The feeding mechanism includes a first conveying member 2 for delivering the bottom film one by one, a first clamping member 3 for transferring the bottom film on the first conveying member 2 to the operating table, a second conveying member 4 for delivering the hook body one by one, and a second clamping member 5 for transferring and pressing the hook body on the second conveying member 4 on the bottom film. When bonding the hook, the first conveying member 2 continuously delivers the bottom film one by one, the first clamping member 3 clamps the bottom film on the first conveying member 2 and places it steadily on the operating table, and then the glue dispensing mechanism 6 drips adhesive on the bottom film, the second conveying member 4 continuously delivers the hook body one by one, and the second clamping member 5 clamps the hook body on the second conveying member 4 and transfers and presses it on the bottom film, so that the hook body is stably bonded to the bottom film, thereby completing the bonding of the hook.

[0034] In order to improve the production quality and efficiency of hooks, refer to Figure 1 , Figure 2 and Figure 3 The operating table includes a table body 10 and a turntable 11 rotatably mounted on the table body 10. The table body 10 is provided with a turntable for driving the turntable 11 to rotate automatically. The turntable 11 is provided with a plurality of placement slots 1 for placing the film. The plurality of placement slots 1 are evenly distributed along the circumference of the turntable 11, thereby forming a plurality of workstations. In the embodiment of the present application, there are five workstations. The first conveying member 2 and the second conveying member 4 are both arranged on the table body 10. Since the second clamping member 5 not only needs to clamp the hook body on the second conveying member 4 and transport it to the film on the turntable 11, but also needs to press the hook body on the film, the second clamping member 5 is arranged on the turntable 11, and the number of the second clamping members 5 is the same as the number of workstations, which is also five, and the five second clamping members 5 correspond to the five workstations one by one. When the turntable 11 drives the second clamping member 5 to rotate to the second conveying member 4, the second clamping member 5 can clamp the hook body on the second conveying member 4 and transfer it to the film on the turntable 11, and as the turntable 11 rotates, the second clamping member 5 can press the hook body on the film for a certain period of time, thereby improving the bonding efficiency and quality between the hook body and the film.

[0035] Reference Figure 3 and Figure 4The second clamping member 5 includes a second rotating seat 51 rotatably mounted on the turntable 11, a lifting member mounted on the second rotating seat 51, and an electric clamp 53 fixed on the output end of the lifting member. The second conveying member 4 is configured as a vibration disk, and the feeding end of the vibration disk is arranged close to the edge of the turntable 11, so that the hook body is arranged in order and transmitted to the edge of the turntable 11 under the vibration of the vibration disk. The rotation axis of the second rotating seat 51 is vertically arranged, and the second rotating seat 51 is located on the side of the placement slot 1 close to the edge of the turntable 11. The lifting member is configured as a small lifting cylinder 52, and the cylinder body of the lifting cylinder 52 is fixed in the middle of the second rotating seat 51. The output end of the lifting cylinder 52 is fixed with a horizontal plate 17, and the lifting cylinder 52 can push the horizontal plate 17 to move stably up and down. The electric clamp 53 is fixed on the horizontal plate 17. According to production requirements, the electric clamp 53 on the horizontal plate 17 can be provided with multiple electric clamps 53. In the embodiment of the present application, two electric clamps 53 are provided on the horizontal plate 17, and the two electric clamps 53 are spaced apart along the radial direction of the turntable 11. At the same time, two placement slots 1 corresponding to each station on the turntable 11 are also provided, and the two placement slots 1 on the same station are also spaced apart along the radial direction of the turntable 11. As the lifting cylinder 52 drives the horizontal plate 17 to rise and fall, and the second rotating seat 51 drives the lifting cylinder 52 to rotate, the electric clamp 53 can clamp the hook body on the feeding end of the vibrating plate and transfer and load it on the bottom film in the placement slot 1.

[0036] For the configuration of the first conveying member 2, refer to Figure 1 , Figure 2 and Figure 5 The first conveying member 2 includes a conveyor belt 21 inclined toward the turntable 11 and a limit member for limiting the film from slipping off the conveyor belt 21. The end of the conveyor belt 21 extends to the top of the turntable 11. Two groups of conveying channels are arranged on the conveyor belt 21. Multiple films are transported in both groups of conveying channels. The films are placed perpendicular to the conveyor belt 21. Multiple films are stacked one by one in the conveying channels along the inclined direction of the conveyor belt 21. By starting the conveyor belt 21, the films can be transported one by one toward the turntable 11, so that the first clamping member 3 can clamp two films at the same time and place them respectively in the two placement slots 1 at the same workstation. In order to prevent the film at the end of the conveyor belt 21 from sliding freely before being clamped by the first clamping member 3, a limiter is set at the end of the conveyor belt 21. In the embodiment of the present application, the limiter is a baffle 22 installed on the end of the conveyor belt 21; the baffle 22 is fixed to the frame of the conveyor belt 21 by screws, and the baffle 22 is arranged perpendicular to the conveyor belt 21, and the baffle bars on the upper and lower sides of the baffle 22 can block the upper and lower edges of the film. Since the film is made of plastic material and has a certain degree of flexibility, the baffle 22 can prevent the film from sliding off the end of the conveyor belt 21 when the first clamping member 3 does not clamp the film; and when the first clamping member 3 clamps the film, it can drive the film to move out from the middle of the baffle bars on the upper and lower sides of the baffle 22, thereby completing the clamping and transfer of the film.

[0037] Considering that the thickness of the bottom film is relatively thin, it is easy to fall on the conveyor belt 21, so that the bottom film cannot be placed vertically on the conveyor belt 21, thereby affecting the first clamping member 3 to clamp the bottom film. Figure 5 , an anti-reversal device 7 for preventing the negative film from tilting is provided on the conveyor belt 21. In the embodiment of the present application, the anti-reversal device 7 includes a pressing block 71 and pulleys 72 rotatably installed on both sides of the pressing block 71, the pressing block 71 is slidably arranged in the conveying channel of the conveyor belt 21, and the pulleys 72 on both sides of the pressing block 71 are respectively slidably abutted against the side plates on both sides of the conveying channel, so that under the action of gravity, the pulleys 72 can slide on the side plates, thereby driving the pressing block 71 to move toward the end of the conveyor belt 21, until the pressing block 71 presses a pile of negative films against one side of the baffle frame 22, ensuring that the negative films between the pressing block 71 and the baffle frame 22 are always arranged vertically on the conveyor belt 21.

[0038] Although the film in the conveying channel is always arranged perpendicular to the conveyor belt 21, ensuring that the first clamping member 3 can stably and efficiently clamp the film, after the first clamping member 3 clamps the film, it is necessary to align the film and place it in the placement slot 1 on the turntable 11. If the film is not aligned and placed in the placement slot 1, it will affect the subsequent bonding position of the hook body on the film, thereby affecting the production quality of the hook. For this reason, refer to Figure 5 When the conveyor belt 21 is transporting the films one by one, it is necessary to make the multiple films on the conveyor belt 21 always in a neatly arranged state. Therefore, the width of the transmission channel on the conveyor belt 21 is set to be consistent with the width of the films. At the same time, when manually placing multiple films on the conveyor belt 21, it is necessary to press the films so that the bottom of the films are pressed tightly against the conveyor belt 21. Considering that when the films are placed manually, some films fail to be pressed tightly against the conveyor belt 21, a pressing device 8 for pressing the films tightly against the conveyor belt 21 is also provided on the conveyor belt 21. In the embodiment of the present application, the pressing device 8 includes a pressing cylinder 82 and a pressing plate 81, the pressing cylinder 82 is fixed on the baffle frame 22, the pressing plate 81 is fixed on the output end of the pressing cylinder 82, and the pressing plate 81 is located on the side of the baffle frame 22 away from the end of the conveyor belt 21. The output end of the pressing cylinder 82 is vertically raised and lowered on the conveyor belt 21, and the pressing plate 81 is arranged vertically on the output end of the pressing cylinder 82, and the end of the pressing plate 81 away from the end of the conveyor belt 21 tilts away from the conveyor belt 21. According to the size of the film, the height from the output end of the pressing cylinder 82 to the conveyor belt 21 is adjusted, so that the film can be vertically abutted on the conveyor belt 21 under the transmission of the conveyor belt 21 and pushed by the tilted end of the pressing plate 81, and the film can smoothly enter under the pressing plate 81 after being pressed and abutted, and finally be transmitted to the end of the conveyor belt 21.

[0039] In order to realize the rapid clamping and transfer of the film at the end of the conveyor belt 21, refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 , a bracket 16 is installed on the platform 10, and the first clamping member 3 is suspended above the turntable 11 through the bracket 16. In the embodiment of the present application, the first clamping member 3 includes a first rotating seat 31 rotatably installed on the bracket 16, a telescopic member installed on the first rotating seat 31, and a pneumatic suction cup 33 installed at the end of the telescopic member. The first rotating seat 31 is located at the end of the conveyor belt 21, and its rotation axis is horizontally arranged; the telescopic member is set as a telescopic cylinder 32, and the telescopic direction of the telescopic cylinder 32 is perpendicular to the rotation axis of the first rotating seat 31. The pneumatic suction cup 33 is fixed on the output end of the telescopic cylinder 32, so that under the drive of the first rotating seat 31 and the telescopic cylinder 32, the pneumatic suction cup 33 can suck the film at the end of the conveyor belt 21 and transfer it to the placement slot 1 on the turntable 11. Taking into account that there are two groups of parallel transmission channels on the conveyor belt 21, and there are two placement slots 1 on the same workstation along the radial direction of the turntable 11, in order to be able to clamp the films in the two transmission channels at the same time and place them in the corresponding two placement slots 1 respectively, a third rotating seat 18 is installed at the end of the telescopic cylinder 32, and two groups of pneumatic suction cups 33 are provided. Both groups of pneumatic suction cups 33 are installed on the third rotating seat 18, so that the two groups of pneumatic suction cups 33 can respectively absorb the films in the two transmission channels, and then the third rotating seat 18 drives the two groups of pneumatic suction cups 33 to rotate, so that the two groups of pneumatic suction cups 33 can align the two films and place them in the two placement slots 1 respectively. In order to avoid the situation that there is no film on the conveyor belt 21 and the pneumatic suction cup 33 has no film to clamp, an alarm device 9 for monitoring the film on the conveyor belt 21 is provided at the end of the conveyor belt 21. The alarm device 9 is an infrared probe installed on the frame at the end of the conveyor belt 21. The infrared probe can detect whether there is any film to be clamped at the end of the conveyor belt 21. When it is detected that the amount of film on the conveyor belt 21 is insufficient, the alarm device 9 will sound an alarm to remind the staff to replenish the material in time.

[0040] After placing the film in the placement slot 1 and before clamping the adhesive hook body, the film needs to be transferred to the glue dispensing mechanism 6 by the turntable 11 for dripping the adhesive, so refer to Figure 1 , Figure 2 , Figure 3 and Figure 7, a frame 15 is installed on the platform 10, and the glue dispensing mechanism 6 is suspended above the turntable 11 through the frame 15. The glue dispensing mechanism 6 includes two glue dispensing tubes 61 vertically fixed on the frame 15, a glue connection box 62 located at the bottom of the two glue dispensing tubes 61, and a driving member installed on the frame 15. The two glue dispensing tubes 61 are arranged at intervals along the radial direction of the turntable 11, and the glue connection box 62 is fixedly connected to the output end of the driving member. The driving member is configured as a driving cylinder 63, which can drive the glue connection box 62 to reciprocate at the bottom of the glue dispensing tube 61, thereby realizing the opening and closing of the glue outlet of the glue dispensing tube 61. When the turntable 11 drives the film to rotate below the glue dispensing tube 61, the driving cylinder 63 drives the glue box 62 to move away from the glue dispensing tube 61, so that the lower end of the glue dispensing tube 61 is exposed, and the glue dispensing tube 61 can drip adhesive on the film below it; when the adhesive is dripped, the driving cylinder 63 drives the glue box 62 to move toward the glue dispensing tube 61, so that the lower end of the glue dispensing tube 61 is blocked by the glue box 62, avoiding excess adhesive from dripping on the turntable 11. At the same time, the turntable 11 drives the film after glue dispensing to rotate away from the glue dispensing mechanism 6. As the turntable 11 rotates, the second clamping member 5 can transfer the clamped hook body and pressurize it on the film, so that the film and the hook body are quickly bonded.

[0041] To speed up the bonding of the hook and the bottom film, refer to Figure 3 A first curing device 12 for accelerating the curing of the adhesive is arranged in the placement groove 1. The first curing device 12 is arranged as a small UV curing lamp, which can accelerate the curing speed of the adhesive so that the base film can be bonded to the hook body in a short time.

[0042] In order to continuously complete the bonding of the hook, refer to Figure 1 and Figure 2 A finished product conveyor belt 13 is provided on one side of the turntable 11 on the platform 10. The finished product conveyor belt 13 is transported in a direction away from the platform 10. After the second clamping member 5 clamps the hook body and presses it on the bottom film, the second clamping member 5 moves to the finished product conveyor belt 13 together with the bottom film and the hook body under the drive of the turntable 11. Then the second clamping member 5 can clamp the hook body and the bottom film and place them on the finished product conveyor belt 13, so that the hook formed by the adhesion of the hook body and the bottom film moves in a direction away from the turntable 11 to unload, thereby facilitating the subsequent first clamping member 3 to clamp the bottom film to be bonded and place it on the turntable 11. In order to further promote the stable adhesion of the hook body and the bottom film on the finished product conveyor belt 13, a second curing device 14 for further accelerating the curing of the adhesive is provided on the finished product conveyor belt 13. The second curing device 14 is set as a large UV curing lamp, which can further cure the hook body and the bottom film on the finished product conveyor belt 13, thereby ensuring the production quality of the hook.

[0043] The implementation principle of a fully automatic plastic hook bonding machine in the embodiment of the present application is as follows: first start the first conveying member 2 and the second conveying member 4, the first conveying member 2 conveys the film toward the turntable 11, and the second conveying member 4 conveys the hook body toward the turntable 11. Then start the first clamping member 3, the first clamping member 3 clamps the film on the first conveying member 2 and places it in the placement slot 1 on the turntable 11. The turntable 11 drives the film to rotate below the glue dispensing mechanism 6, and then starts the driving cylinder 63, the driving cylinder 63 drives the glue box 62 to move away from the glue dispensing tube 61, so that the lower end of the glue dispensing tube 61 is exposed, and the glue dispensing tube 61 can drip adhesive on the film below it; when the adhesive dripping is completed, the driving cylinder 63 drives the glue box 62 to move toward the glue dispensing tube 61, so that the lower end of the glue dispensing tube 61 is blocked by the glue box 62, and the excess adhesive is prevented from dripping on the turntable 11. While dripping the adhesive, the second clamping member 5 is started, and the second clamping member 5 clamps the hook body on the second conveying member 4. Then the turntable 11 drives the bottom film and the hook body to rotate away from the dispensing mechanism 6. At this time, the second clamping member 5 transfers and presses the clamped hook body on the bottom film, so that the hook body and the bottom film are bonded. The turntable 11 continues to rotate, and the second clamping member 5 continues to press the hook body on the bottom film until the turntable 11 drives the hook body and the bottom film to rotate to the finished product conveyor belt 13. At this time, the second clamping member 5 is started, and the second clamping member 5 clamps and transfers the bonded hook body and bottom film to the finished product conveyor belt 13. The finished product conveyor belt 13 transfers the hook body and the bottom film away from the turntable 11.
