Description

Technical Field

[0001] This application relates to the field of packaging box manufacturing technology, and in particular to a bonding device. Background Technology

[0002] In the production of some packaging boxes, it is necessary to attach kraft paper to the inner side of the frame. In related technologies, the frame is transported vertically to the laminating device so that the inner side of the frame is at the bottom. The laminating device's robotic arm guides one end of the kraft paper into the frame and attaches it to the inner side from top to bottom. When the packaging box is a product such as a cigarette box, the frame is relatively long, and placing it vertically makes it prone to tipping over or becoming unstable, resulting in poor lamination accuracy and a higher likelihood of defective products.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] Reference Figures 1 to 4 According to an embodiment of this application, the bonding device includes a conveying mechanism 300. The conveying mechanism 300 includes a moving driver 310, a rotating driver 320, and a suction head 330. The moving driver 310 drives and connects to the rotating driver 320 to move the rotating driver 320 closer to or away from the middle frame. The rotating driver 320 drives and connects to the suction head 330 to switch between a horizontal and a vertical state. The suction head 330 includes a connecting block 331 and a connecting piece 332. The rotating driver 320 is connected to the connecting block 331, and the connecting piece 332 is connected to the connecting block 331. Both the connecting piece 332 and the connecting block 331 are provided with suction cups 333, which are used to adsorb bonding materials.

[0034] Understandably, the process of attaching the bonding material to the middle frame is as follows: The horizontally placed middle frame is conveyed to the side of the conveying mechanism 300. The moving driver 310 drives the rotating driver 320 to move the suction head 330 close to the horizontally placed bonding material to be picked up. At this time, the suction head 330 is in a horizontal state, and the suction head 330 picks up the bonding material by suction. Subsequently, the moving driver 310 drives the rotating driver 320 to move the suction head 330 close to the middle frame. During this process, the rotating driver 320 drives the suction head 330 to rotate to a vertical state, and the suction head 330 carries one end of the bonding material into the middle frame. The suction head 330 attaches one end of the bonding material to the inner side of the middle frame, thus completing the bonding of the bonding material to the inner side of the horizontally placed middle frame. Specifically, the suction head 330 includes a connecting block 331 and a connecting piece 332 connected to each other. Both the connecting block 331 and the connecting piece 332 are equipped with suction cups 333 to adsorb and adhere to the material. The rotary driver 320 drives the connecting block 331 to rotate, which in turn drives the connecting piece 332 to rotate. It should be understood that the material to be adhered to is relatively long, so the suction head 330 needs to be relatively long. The suction head 330 is divided into the connecting block 331 and the connecting piece 332. The connecting block 331 is thicker to ensure the stability of the connection with the rotary driver 320, while the connecting piece 332 is thinner and longer. The connecting piece 332 is longer than the suction head 330. Thus, the overall size of the suction head 330 can be kept relatively long while keeping the weight of the suction head 330 low, reducing the load on the rotary driver 320 and improving the driving stability of the rotary driver 320.

[0035] As can be seen from the above, by using the rotary driver 320 in conjunction with the suction head 330, the bonding material grasped by the suction head 330 can be rotated to a vertical position, and then, in conjunction with the moving driver 310, the bonding material is bonded to the inner side of the horizontally placed middle frame, thereby achieving bonding to the inner side of the horizontally placed middle frame. The horizontally placed middle frame is conveyed stably, and the bonding accuracy is good. Furthermore, by dividing the suction head 330 into a connecting block 331 connected to the rotary driver 320 and a connecting piece 332 with a certain length, it is possible to ensure that the length of the suction head 330 can grasp a relatively long bonding material, while also ensuring the connection stability between the suction head 330 and the rotary driver 320, as well as the driving stability of the rotary driver 320.

[0036] Specifically, the moving drive 310 includes a vertical lead screw module and a horizontal lead screw module. The vertical lead screw module is located at the drive end of the horizontal lead screw module, and the rotary drive 320 is located at the drive end of the horizontal lead screw module. The horizontal lead screw module drives the rotary drive 320 and the suction head 330 to move horizontally through the vertical lead screw module, and the vertical lead screw module drives the suction head 330 to move vertically through the rotary drive 320.

[0037] Reference Figure 1 , Figure 5 and Figure 6 According to some embodiments of this application, it also includes a feeding mechanism 200, which includes a hopper 210, a feeding platform 220, a picking component 230, and a pushing component 240. The feeding platform 220 has a picking position 223 and a dropping position 221. The hopper 210 is disposed on the feeding platform 220 and corresponds to the dropping position 221. The hopper 210 has a storage space 211 for stacking bonding materials along the height direction. The wall of the storage space 211 is provided with a support member 212 for supporting the stacked bonding materials. The picking component 230 is used to pull the bonding material closest to the dropping position 221 among the stacked bonding materials to the dropping position 221. The pushing component 240 is used to push the bonding material at the dropping position 221 to the picking position 223. The moving driver 310 can drive the rotating driver 320 to move the suction head 330 closer to or away from the picking position 223.

[0038] Understandably, the process by which the feeding mechanism 200 transports the bonding material to the picking position 223 is as follows: the picking component 230 grabs the bottommost bonding material stacked in the storage space 211 and pulls it out of the storage space 211 so that the bonding material falls onto the dropping position 221 of the feeding platform 220. Subsequently, the pushing component 240 pushes the bonding material at the dropping position 221 to the picking position 223, and the moving driver 310 drives the suction head 330 to approach the picking position 223 and remove the bonding material from the picking position 223.

[0039] Reference Figure 5 and Figure 7 According to some embodiments of this application, the material picking assembly 230 includes a lifting driver 231 and a picking head 232. The lifting driver 231 drives the picking head 232 to pass through the drop position 221 along the height direction and move closer to or away from the storage space 211. The picking head 232 is used to pick up the bottommost of the stacked bonding materials.

[0040] Understandably, the process by which the picking assembly 230 moves the bonding material in the storage space 211 to the dropping position 221 is as follows: In the initial state, the picking head 232 is lower than the bearing surface of the loading platform 220, i.e., lower than the dropping position 221. The bearing surface of the loading platform 220 is used to support the upper surface of the bonding material. Subsequently, the lifting driver 231 drives the picking head 232 to rise, allowing the picking head 232 to pass through the dropping position 221 and grab the bonding material at the bottom of the storage space 211. Next, the lifting driver 231 drives the picking head 232 to fall, the picking head 232 passes through the dropping position 221 and returns to the initial position, while simultaneously canceling the grabbing of the bonding material. Thus, the picking head 232 pulls the bonding material out of the storage space 211 and allows the bonding material to fall into the dropping position 221.

[0041] Specifically, a through hole 224 is formed at the material drop position 221 on the loading platform 220. The through hole 224 is used to pass through the material pick-up head 232 so that the material pick-up head 232 can be higher or lower than the bearing surface of the loading platform 220 and can pass through the material drop position 221.

[0042] Specifically, the material handling assembly 230 also includes a vacuum generator connected to the material handling head 232. The vacuum generator is used to cause the material handling head 232 to adsorb and adhere to the material. The vacuum generator, connected to the material handling head 232, enables the material handling head 232 to generate suction, allowing the material handling head 232 to grasp the material through adsorption. Of course, in some other embodiments, the material handling head 232 can also grasp and adhere to the material by means of pasting or clamping.

[0043] Specifically, the support member 212 is fixed, while the material being adhered to is relatively soft. When the material-receiving head 232 pulls the material out of the storage space 211, the material can deform to leave the storage space 211. Of course, in some other embodiments, the support member 212 can also be an elastic member or hinged to the inner wall of the storage space 211 to reduce friction between the support member and the material when the material is pulled out of the storage space 211.

[0044] Reference Figure 5 According to some embodiments of this application, the feeding mechanism 200 further includes a folding component 270, which includes a folding driver 271 and a folding head 272. The folding driver 271 is disposed on the feeding table 220 and located beside the material picking position 223. The folding driver 271 drives the folding head 272 to move closer to or away from the connecting block 331. The folding head 272 is used to cooperate with the connecting block 331 to bend and fit the material.

[0045] Understandably, during the process of the bonding material being pushed to the material picking position 223 and the conveying mechanism 300 approaching the material picking position 223 to pick up the bonding material, the connecting block 331 in the conveying mechanism 300 can first press down on the bonding material, and cooperate with the loading table 220 to limit the bonding material. It should be understood that the connecting block 331 is offset from the edge of the bonding material near the bending component. Thus, after the connecting block 331 presses down on the bonding material, the folding driver 271 drives the folding head 272 to approach the connecting block 331. The folding head 272 pushes one end of the bonding material, and the folding head 272 cooperates with the connecting block 331 to bend one end of the bonding material, so that the bent end of the bonding material can be bonded to the inner side of the middle frame later.

[0046] Reference Figure 5 According to some embodiments of this application, the feeding mechanism 200 further includes a spring sheet 280, which is disposed between the dropping position 221 and the picking position 223, and a gap is formed between the spring sheet 280 and the feeding table 220 for passing the material.

[0047] It is understandable that when the pusher assembly 240 pushes the bonding material from the drop position 221 to the pick-up position 223, the bonding material will pass through the gap between the aforementioned spring 280 and the loading table 220, so as to limit the bonding material in the height direction and ensure the stable transmission of the bonding material.

[0048] Reference Figure 7 According to some embodiments of this application, the feeding assembly 240 includes a lifting driver 241, a horizontal driver 242, and a pusher block 243. The horizontal driver 242 drives the pusher block 243 to move along the distribution direction of the dropping position 221 and the picking position 223. The lifting driver 241 drives the pusher block 243 to make the pusher block 243 higher or lower than the bearing surface of the loading platform 220.

[0049] Understandably, the process by which the pushing assembly 240 pushes the bonding material at the dropping position 221 to the picking position 223 is as follows: In the initial state, the pusher block 243 is located on the side of the dropping position 221 away from the picking position 223 and protrudes from the bearing surface of the loading platform 220. After the picking assembly 230 moves the bonding material to the dropping position 221, the horizontal driver 242 drives the pusher block 243 to move along the distribution direction of the dropping position 221 and the picking position 223, and the pusher block 243 pushes the bonding material at the dropping position 221 to the picking position 223. Subsequently, the lifting driver 241 drives the push block 243 to descend, so that the push block 243 is lower than the bearing surface of the loading table 220, so that the push block 243 avoids contact with the material when it returns to the initial position. Then, the horizontal driver 242 drives the push block 243 back to the initial position, and the lifting driver 241 drives the push block 243 to rise above the bearing surface of the loading table 220, so that the push block 243 returns to one side of the dropping position 221.

[0050] Reference Figure 7 According to some embodiments of this application, the loading platform 220 is provided with a pusher groove 225, which extends from the dropping position 221 to the picking position 223. The pusher block 243 can slide horizontally along the pusher groove 225 and can pass through the pusher groove 225 to be higher or lower than the bearing surface of the loading platform 220.

[0051] Understandably, the pusher block 243 can slide along the pusher groove 225 to push the bonding material, and the pusher block 243 can pass through the pusher groove 225 under the action of the lifting driver 241 to be higher or lower than the bearing surface of the loading table 220, thereby avoiding the bonding material and returning to the initial position.

[0052] Reference Figure 5According to some embodiments of this application, the feeding mechanism 200 further includes a pressing component 250 and an adhesive application component 260. The feeding platform 220 forms a pressing position 222 between the dropping position 221 and the picking position 223. The pressing component 250 is set corresponding to the pressing position 222 and is used to press the bonding material located at the pressing position 222. The adhesive application component 260 is used to apply adhesive to the bonding material pressed by the pressing component 250.

[0053] Understandably, during the process of the pusher assembly 240 pushing the bonding material from the drop position 221 to the pick-up position 223, the bonding material will first reach the pressing position 222. The pressing assembly 250 can press down the bonding material at the pressing position 222 to limit the bonding material. Subsequently, the gluing assembly 260 can apply glue to the bonding material pressed down by the pressing assembly 250 so that the bonding material can be bonded to the middle frame.

[0054] Reference Figure 3 According to some embodiments of this application, the rotary driver 320 includes a drive cylinder 321, a swing gear 322, and a connecting frame 323. The mobile driver 310 is connected to the body end of the drive cylinder 321. The output end of the drive cylinder 321 is provided with a rack structure 3211. The connecting frame 323 is fixedly connected to the body end of the drive cylinder 321. The swing gear 322 meshes with the rack structure 3211 and is rotatably connected to the connecting frame 323. The swing gear 322 is fixedly connected to the connecting block 331.

[0055] Understandably, the process by which the rotary driver 320 drives the suction head 330 to switch between vertical and horizontal states is as follows: the drive cylinder 321 extends and retracts its output end, causing the rack structure 3211 to move relative to the oscillating gear 322. The oscillating gear 322 rolls on the rack structure 3211, thereby causing the oscillating gear 322 to rotate relative to the connecting frame 323 and drive the connecting block 331 to rotate, thus realizing the rotation of the suction head 330 and allowing the suction head 330 to switch between horizontal and vertical states.

[0056] Reference Figure 3 and Figure 4 According to some embodiments of this application, the connecting frame 323 is provided with a first limiting member 334 and a second limiting member 335. When the suction head 330 rotates to a horizontal state, the suction head 330 abuts against the first limiting member 334. When the suction head 330 rotates to a vertical state, the suction head 330 abuts against the second limiting member 335.

[0057] It is understandable that when the suction head 330 rotates to a horizontal position, the connecting block 331 of the suction head 330 can abut against the first limiting member 334, and when the suction head 330 rotates to a vertical position, the connecting block 331 of the suction head 330 can abut against the second limiting member 335, thereby limiting the swing range of the suction head 330, and the suction head 330 can be determined to have rotated to a horizontal or vertical position by the abutment state of the suction head 330 against the first limiting member 334 or the second limiting member 335.

[0058] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
