Description

Technical Field

[0001] This utility model relates to the field of packaging box stacking technology, and in particular to an automatic stacking machine for easy-tear aluminum foil lids of lunch boxes. Background Technology

[0002] In the food packaging industry, efficiently and neatly stacking the stamped aluminum foil easy-tear lids for lunch boxes has been a long-standing challenge in the production and packaging process. Because aluminum foil lids are thin, smooth, and prone to static electricity, they easily stick together. Traditional stacking methods rely heavily on manual labor or simple mechanical devices, which have the following significant drawbacks: High material handling failure rate: Traditional vacuum suction cups often pick up multiple pieces at once due to adhesion, causing subsequent processes to be stuck or the stacking quantity to be incorrect, which seriously affects production efficiency.

[0003] Poor stacking quality: When stacking manually or using simple machinery, misalignment or displacement can easily occur, resulting in uneven stacking and affecting subsequent automated packaging or packaging.

[0004] Therefore, there is an urgent need for a device that can fundamentally solve the problem of aluminum foil cover adhesion and achieve high-precision, high-efficiency, and high-reliability automated stacking. Utility Model Content

[0005] Therefore, it is necessary to provide an automatic stacking machine for easy-tear aluminum foil lids of lunch boxes that can actively separate adhered aluminum foil lids, achieve precise positioning and stacking, and operate stably and efficiently, in response to the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automatic stacking machine for easy-tear aluminum foil lids of lunch boxes includes: The frame includes two parallel legs; A three-axis displacement module, mounted on the frame, is used to pick up a single aluminum foil cover from the feeding module and transfer it to the stacking position; The vibration detachment mechanism is located at the moving end of the triaxial displacement module and is used to generate vibration; An adsorption mechanism, installed on the end effector of the vibration detachment mechanism, is used to adsorb the aluminum foil cover; A stacking platform module, located downstream of the feeding module, is used to receive and stack aluminum foil covers transferred by the adsorption mechanism; The air knife detachment component is set on the side wall of the vibration detachment mechanism and arranged perpendicularly to the adsorption mechanism. It blows out a thin sheet of airflow to "cut" into the bottom of the top cover from the side and separate the aluminum foil cover.

[0007] Furthermore, the triaxial displacement module includes an X-axis lead screw module located at the top of the frame, a Y-axis lead screw module located at the moving end of the X-axis lead screw module, and a Z-axis lead screw module installed at the moving end of the Y-axis lead screw module. This lead screw module structure has the advantages of high transmission accuracy, good rigidity, and accurate positioning, which can ensure that the motion trajectory of the adsorption mechanism in three-dimensional space is precise and controllable.

[0008] Furthermore, the vibration release mechanism is an electromagnetic vibrator. Four sets of sliding chambers are located at the four corners of the bottom of the vibration release mechanism. The electromagnetic vibrator has a fast response speed, precise control, and can generate stable high-frequency micro-vibrations. The design of the four sets of sliding chambers provides precise guidance and installation benchmarks for subsequent elastic connections.

[0009] Furthermore, the adsorption mechanism includes a four-way flow guide seat, with slide rods fixedly connected to the four corners of the four-way flow guide seat. The slide rods are slidably inserted into the interior of the slide chamber. This "slide rod-slide chamber" matching structure ensures that the adsorption mechanism can move together with the vibration detachment mechanism, while also providing it with independent vibration degrees of freedom.

[0010] Furthermore, a spring is arranged at one end of the slide rod, and the slide rod elastically engages with the vibration detachment mechanism through the spring. The middle part of the four-way guide seat abuts against the vibration detachment mechanism. The spring design is one of the key innovations of this utility model. It creates a "flexible connection" between the adsorption mechanism and the vibration detachment mechanism. When the vibration detachment mechanism is activated, the vibration energy is transmitted to the adsorption mechanism through the spring, causing it to generate high-frequency micro-vibrations. This vibration acts directly on the adsorbed aluminum foil cover, effectively shaking off any extra cover pieces that may be stuck together, thus achieving the function of "secondary separation after adsorption".

[0011] Furthermore, suction cups can be detachably connected to the four corners of the four-way flow guide seat. The suction cups are connected to the four-way flow guide seat through air pipes, and the four-way flow guide seat is connected to an external air pump through a conduit. The four-way design ensures that the vacuum degree of the four suction cups is uniform and consistent. The detachable connection makes it easy to replace suction cups of different specifications according to different sizes of aluminum foil covers, thus enhancing the versatility of the equipment.

[0012] Furthermore, the air knife detachment assembly includes an air plate, which is fixedly connected to the vibration detachment mechanism via a bracket. The tail end of the air plate is connected to a gas supply pump via a corrugated hose. By directly mounting the air knife detachment assembly on the vibration detachment mechanism, synchronous movement of the air knife and the adsorption mechanism is achieved. No matter which position the adsorption mechanism moves to, the air knife can maintain the optimal relative position and spray angle, resulting in excellent linkage.

[0013] Furthermore, the inner wall of the gas disk has a circular buffer chamber and multiple airflow dispersion channels. The inlet of the airflow dispersion channel is inclined, and the outlet is a parallel straight surface. The circular buffer chamber can stabilize and buffer the incoming high-pressure gas, which is then discharged through the specially designed airflow dispersion channels. The inclined inlet helps guide the airflow to enter smoothly, while the parallel straight outlet can constrain the gas, forming a thin, blade-like airflow with uniform velocity and stable shape, ensuring precise and efficient separation.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides an automatic stacking machine for easy-tear aluminum foil lids on lunch boxes. This invention integrates two mechanisms: "air knife separation" and "vibration separation". The air knife performs "pre-separation" before picking up the material, and the vibration mechanism performs "secondary separation" after picking up the material. This dual protection ensures that each adsorption produces a single piece, fundamentally solving the adhesion problem. The use of a high-precision three-axis ball screw module, combined with the precise positioning of the stacking platform module, ensures the positional accuracy of aluminum foil cover transfer and stacking; The entire process requires no human intervention, realizing a fully automated assembly line operation from material supply to finished product stacking, which improves production efficiency several times and effectively reduces labor costs; The vibration mechanism, adsorption mechanism and air knife assembly are integrated into a compact functional module. The three move synchronously and respond quickly, reducing complex pipeline layout and external coordination control, and simplifying the overall structure of the equipment. The detachable suction cup design and modular structure allow the device to quickly adapt to products of different specifications, while also facilitating daily maintenance and replacement.
