Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6This embodiment of a plastic cap decal device includes an operating table 1, on which a rotating table 3 is mounted, and an upper cap assembly 2, a decal assembly 5, and a lower cap assembly 6 are distributed around the rotating table 3. Multiple adsorption stations 4 are mounted on the rotating table 3. These adsorption stations 4 are used to adsorb and fix the plastic cap, ensuring the stability of the plastic cap during the decal application process. With the coordinated operation of the upper cap assembly 2, the decal assembly 5, and the lower cap assembly 6, the device achieves automatic feeding, automatic decal application, and automatic unloading of the plastic cap, requiring no manual intervention throughout the process, significantly improving production efficiency and meeting the needs of large-scale production.

[0024] like Figure 2 As shown in the diagram, the upper cover assembly 2 includes a base plate 21 fixed on the operating table 1. A plate base 24 is fixed to the top of the base plate 21, and four guide rods 22 pass through it. A pushing cylinder 25 is installed on the top of the plate base 24. The piston rod of the pushing cylinder 25 is fixed to a pushing plate 23 connected to the guide rods 22. A rotary cylinder 26 is installed on the top of the pushing plate 23, and a cover-clamping cylinder 27 is installed at the rotating end of the rotary cylinder 26. The pushing cylinder 25 drives the pushing plate 23 to rise and fall, and the rotary cylinder 26 drives the cover-clamping cylinder 27 to rotate. The cover-clamping cylinder 27 grabs the outer plastic cover and places it onto the adsorption station 4 of the rotating table 3, achieving automatic feeding.

[0025] like Figure 3-5The decal assembly 5 includes a stand 51 and a side frame 511 fixed on the operating table 1. A recessed platform 52 is fixed to the top of the stand 51. The length of the recessed platform 52 is greater than the length of the stand 51. The recessed platform 52 is connected to an external vibrating feeding device to guide and convey the decal pieces to be decaled. Side guards 53 extending to the concave surface of the recessed platform 52 are fixed to the convex edges of the recessed platform 52, and a tail guard 54 is fixed to the tail end. The side guards 53 and the tail guard 54 work together to prevent the decal pieces from falling off. A horizontal plate 55 is fixed to the bottom of the tail end of the recessed platform 52. An upper-lifting cylinder 59 located below the recessed platform 52 is installed on the front of the stand 51. The piston rod of the upper-lifting cylinder 59 can pass through the horizontal plate 55 and the recessed platform 52 in sequence and is fixed with a silicone head 510. The silicone head 510 has a certain degree of adhesion, which can stably adhere the decal pieces while avoiding damage to the surface of the decal pieces. The telescopic drive of cylinder 59 raises and lowers the silicone head, with stable and controllable movement. Both ends of the top of the horizontal plate 55 are equipped with opposing cylinders 56. The piston rods of the two sets of opposing cylinders 56 are respectively fixed with staggered correction plates 57 and limiting plates 58. The correction plate 57 can extend into the interior of the recessed platform 52 and is opposite to one of the convex edges. The limiting plate 58 is L-shaped and has a U-shaped opening in its cross-section. This opening is located above the silicone head. When the decal contacts the tail plate, the opposing cylinder 56 drives the correction plate 57 to move, so that the decal is in contact with the inner wall of the recessed platform to play a correction role. Then, the opposing cylinder drives the limiting plate 58 to move relative to each other, so that the lower part of the U-shaped opening is above the decal. When the upper cylinder drives the silicone head to lift the decal to the limit height of the U-shaped plate opening, the silicone head maintains the pressing state to ensure the accurate position of the decal.

[0026] Among them, such as Figure 4 A first linear module 512 is mounted on the front of the side frame 511. The first linear module 512 moves horizontally. A vertically downward-moving cylinder 513 is mounted on the moving end of the first linear module 512, which moves vertically. The piston rod of the lower cylinder 513 is fixed to a lower top plate 514. A pair of uprights 515 are mounted on the lower top plate 514. A lower plate 516 is fixed between the bottoms of the uprights 515. An adsorption head 518 is mounted on the bottom of the lower plate 516. Four protrusions 519 are fixed to the outside of the adsorption head 518. The protrusions 519 are used to contact the U-shaped decal when removing it. The opening shape helps to limit the suction head, ensuring that it contacts and adsorbs the decal. Simultaneously, when the lower cylinder applies downward pressure, the column moves the lower plate upward, preventing excessive downward pressure from damaging the suction head. Furthermore, when the decal is too heavy, the weight of the lower plate, column, suction head, and protrusions presses it firmly onto the plastic cover, ensuring a tight fit. Driven by the first linear module, the suction head moves to directly above the decal, and the lower cylinder drives it downward, contacting the decal and creating negative pressure for adsorption. Then, the silicone head retracts under the drive of the upper cylinder, completing the material transfer process.

[0027] In addition, a flower-clamping cylinder 517 is installed at the bottom of the lower top plate 514. The clamping end of the flower-clamping cylinder 517 is adapted to the adsorption head 518 and the protrusion 519, and a semi-circular groove is opened at the bottom of the clamping end. The inner side of the clamping end of the flower-clamping cylinder 517 is provided with a flat clamping surface adapted to the thickness of the decal, ensuring that the edge of the decal is adhered to achieve auxiliary fixation. Its clamping end is located outside the adsorption head and does not interfere with the adsorption head 518 and the protrusion 519, further ensuring the stability of the decal position during the decal application process and improving the decal application accuracy.

[0028] like Figure 6 The lower cover assembly 6 includes a mounting bracket 61 fixed on the operating table 1. A second linear module 62 is mounted on the front of the mounting bracket 61. A vertically downward pushing cylinder 63 is mounted on the moving end of the second linear module 62. A double-headed cylinder 64 is fixed to the piston rod of the pushing cylinder 63. Clamping plates 65 are fixed to the piston rods at both ends of the double-headed cylinder 64. The clamping plates 65 are U-shaped, and each side of the clamping plates 65 has a slot adapted to the cover body. The double-headed cylinder 64 is driven to move by the second linear module 62 and the pushing cylinder 63. The double-headed cylinder 64 drives the clamping plates 65 to position the decal plastic cover in the slot. At the same time, the corresponding adsorption station stops adsorption. With the cooperation of the second linear module and the pushing cylinder, it can be removed from the adsorption station 4 and transported to the designated position, realizing automatic unloading.

[0029] The working principle of the above embodiments is as follows:

[0030] The push cylinder drives the push plate to rise and fall along the guide rod, adjusting the height of the clamping cylinder. The rotary cylinder drives the clamping cylinder to rotate to the external plastic cover storage location. After the clamping cylinder grabs the plastic cover, it is reset by the rotary cylinder and adjusted in conjunction with the push cylinder to precisely place the plastic cover onto the adsorption station of the rotating table. The adsorption station activates its adsorption function, firmly fixing the plastic cover and completing the automatic feeding process. After feeding is completed, the rotating table rotates, sequentially conveying the adsorption station containing the plastic cover to the corresponding working positions of the decal assembly and the lower cover assembly, realizing the plastic... The process flows smoothly between each stage. An external vibrating feeder transports the decal to the recessed platform. Side and tail stops prevent the decal from falling. Once the decal contacts the tail stop, a push cylinder drives a correction plate to move, ensuring the decal adheres to the inner wall of the recessed platform for positional correction. Subsequently, a push cylinder drives a limiting plate to move, positioning its U-shaped opening above the decal. An upper push cylinder then drives a silicone head to rise, passing through the recessed platform and lifting the decal to the limit height of the U-shaped opening on the limiting plate. The silicone head maintains pressure to ensure accurate decal positioning. The first linear module drives the lower push cylinder and... The adsorption head moves directly above the decal, and the lower cylinder drives the adsorption head to descend. The protrusion engages with the U-shaped opening to limit the movement, ensuring the adsorption head contacts the decal and generates negative pressure for adsorption. Simultaneously, the clamping end of the clamping cylinder closes, assisting in fixing the decal from its edge. Then, the silicone head retracts under the drive of the lower cylinder, completing the decal pickup. The first linear module drives the adsorption head to move directly above the plastic cover on the rotary table adsorption station. The lower cylinder drives the adsorption head to descend, and the weight of the lower plate, column, adsorption head, and protrusion presses the decal onto the plastic cover, ensuring... After the plastic cap is tightly bonded, the suction head releases negative pressure, the clamping cylinder releases, and the suction head resets under the drive of the first linear module and the lower push cylinder. The rotating table transports the plastic cap to the corresponding position of the lower cap assembly. The second linear module and the lower push cylinder drive the double-headed cylinder to move to the plastic cap. The double-headed cylinder drives the clamping plate to open and then close, so that the plastic cap is inserted into the clamping plate's slot. At the same time, the suction station stops suction. Finally, through the cooperation of the second linear module and the lower push cylinder, the decal-coated plastic cap is removed from the suction station and transported to the designated position, completing the automatic unloading.
