Especially in the case of large-scale production, manual operation is difficult to meet the needs of efficient production. As the production scale expands, the time cost required for manual operation will also increase significantly, affecting the overall production efficiency. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-3 In this embodiment, an automatic paper pad placing device is used to automatically place the paper pad into the interior of the carton;

[0025] Specifically, it includes a roller-type transport frame 1 for transporting cartons, a robotic arm 2, a placement frame 3, at least two paper pad placement boxes 4 and a pick-and-place structure 5;

[0026] Two guide frames 6 are provided on the roller-type transmission frame 1 along the X-axis direction. A dual-axis cylinder 601 is provided on one of the guide frames 6. The output end of the dual-axis cylinder 601 is connected to a baffle 602 for driving the baffle 602 to move left and right along the Y-axis direction.

[0027] One of the guide frames 6 is equipped with three photoelectric sensors 603. The front photoelectric sensor 603 is arranged in front of the dual-axis cylinder 601. The placement frame 3 is mounted on the left side of the roller-type transmission frame 1. At least two paper pad placement boxes 4 are arranged on the placement frame 3 along the X-axis direction.

[0028] The robot arm 2 is arranged on the right side of the roller-type transmission frame 1, and the picking and placing structure 5 is arranged on the end effector of the robot arm 2 to suck the paper pad inside the paper pad placement box 4 and place it inside the carton.

[0029] In actual settings, the roller-type transmission frame 1 serves as the main transmission channel for cartons and runs along the X-axis direction to ensure that the cartons can be smoothly transferred from one workstation to the next. On the roller-type transmission frame 1, two guide frames 6 are set up, and a baffle 602 driven by a dual-axis cylinder 601 is installed on one of the guide frames 6. When the photoelectric sensor 603 detects that the carton has arrived at the specified position, the dual-axis cylinder 601 is activated to push the baffle 602 to move along the Y-axis direction to prevent the carton from continuing to move forward, thereby achieving precise positioning of the carton. The middle photoelectric sensor 603 is mainly used to sense the arrival of the carton in advance and provide a trigger signal for the action of the baffle 602.

[0030] In addition, at least two paper pad placement boxes 4 are arranged on the placement rack 3 along the X-axis direction. Each paper pad placement box 4 contains paper pads to be used. These paper pads are prepared in advance so that they can be taken at any time. The robotic arm 2 is located on the right side of the roller-type transmission rack 1, and its end effector is equipped with a pick-up and placement structure 5.

[0031] When the carton is blocked and positioned by the baffle 602, the robotic arm 2 moves to the corresponding paper pad placement box 4 according to the preset program or external instructions, and the picking and placing structure 5 starts working, taking the paper pad out of the placement box by adsorption or other means, and placing it accurately inside the carton. This process realizes the automatic picking and placing of paper pads, greatly improving production efficiency and accuracy.

[0032] It should be noted that there is an opening vertically on the right side of the paper pad placement box 4; the middle photoelectric sensor 603 is arranged opposite to the front carton, and the rear photoelectric sensor 603 is arranged opposite to the rear carton. In addition, a control terminal is also provided inside the entire device, and the photoelectric sensor 603, the dual-axis cylinder 601 and the robotic arm 2 are all electrically connected to the control terminal.

[0033] During actual use, after the robot arm 2 places the paper pad inside the carton, it transmits the information to the dual-axis cylinder 601, causing the baffle 602 to contract, and drives the carton to move through the roller-type transmission frame 1. When the last carton passes through the front photoelectric sensor 603, the front photoelectric sensor 603 transmits the instruction to the terminal, and processes the data through the terminal, and then transmits it to the dual-axis cylinder 601, so that the output end of the dual-axis cylinder 601 extends and pushes the baffle 602 forward to stop the subsequent cartons.

[0034] Furthermore, in order to ensure the stability of carton transmission, a guard plate is provided on the side of the placement rack 3 close to the roller-type transmission rack 1 in this embodiment, and a guide rail 7 is installed on the side of the guard plate opposite to the robotic arm 2. The rear ends of the two guide rails 7 are bent back to back so that the rear ends of the two guide rails 7 are distributed in an eight-shaped shape.

[0035] In actual settings, by setting a guard plate on the side of the placement rack 3 close to the roller-type transmission rack 1, the cartons can be effectively prevented from falling due to vibration or deviation during transportation, thereby enhancing the stability of the cartons on the transportation path and reducing the risk of cargo loss. In addition, the guide rail 7 installed on the guard plate provides a clear transportation path and positioning point for the cartons.

[0036] In particular, the rear ends of the two guide rails 7 are bent back to back into an eight-shaped distribution. This non-linear guide rail 7 layout can better adapt to the initial stage of the carton entering the transmission system, help the carton automatically correct its position, ensure that the carton enters the roller-type transmission frame 1 with the correct posture and angle, and further improve the accuracy and stability of the transmission.

[0037] In detail, in order to facilitate the suction of the paper pad inside the paper pad placement box 4, the picking and placing structure 5 in this embodiment includes a crossbeam 501 that is transmission-connected to the end effector of the robot arm 2; corresponding to the paper pad placement box 4, at least two T-shaped frames 502 are provided on the left side of the crossbeam 501, and the same exhaust pipe 503 is installed on at least two T-shaped frames 502, and at least two connecting pipes 504 are vertically penetrated inside the T-shaped frame 502, and a suction cup 505 is connected to the bottom end of the connecting pipe 504, and the connecting pipe 504 is connected to the exhaust pipe 503 through the air pipe, and the exhaust pipe 503 is connected to the external exhaust equipment.

[0038] During the actual setting, the pick-and-place structure 5 is first connected to the end effector of the robot arm 2 through the crossbeam 501 to ensure that the entire pick-and-place structure 5 can move flexibly with the movement of the robot arm 2. The crossbeam 501 serves as the basis for support and connection, so that subsequent components can be firmly installed and work together. The exhaust pipe 503 is connected to the external exhaust equipment. When the exhaust equipment is started, a negative pressure will be generated in the exhaust pipe 503. This negative pressure is transmitted to each connecting pipe 504 through the air pipe. The connecting pipe 504 vertically passes through the inside of the T-shaped frame 502, and further transmits the negative pressure to the suction cup 505 at its bottom end. The suction cup 505 is a component that directly contacts the paper pad. Its design needs to consider good fit with the surface of the paper pad and sufficient sealing to ensure that the negative pressure can effectively act on the paper pad.

[0039] When the suction cup 505 is in close contact with the paper pad, the suction force generated by the negative pressure will firmly adsorb the paper pad on the suction cup 505. With the precise movement of the robotic arm 2, the picking and placing structure 5 can be accurately positioned above the target paper pad in the paper pad placement box 4. Once the suction cup 505 is in contact with the paper pad and produces effective adsorption, the robotic arm 2 can lift the paper pad from the placement box and move it to the designated position for placement. When placing, by stopping the vacuum or inflating the vacuum pipe 503, the negative pressure between the suction cup 505 and the paper pad disappears, and the paper pad is released and falls to the target position.

[0040] It should be noted that the photoelectric sensor 603 in this embodiment is a sensor that works based on the principle of photoelectric effect. It uses changes in light to detect and convert them into electrical signals or other forms of output signals, thereby realizing the measurement and control of various physical quantities. As an indispensable component of modern automation technology, the photoelectric sensor 603 has been widely used in many fields such as industry, medical care, security, consumer electronics, etc., and has become a very mature and widely used existing technology. Therefore, it will not be described in detail in this application.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
