Technical Field

[0001] The invention relates to the technical field of packaging, and in particular to a vacuum suction device for packaging box plates. Background Art

[0002] In the field of powder packaging technology, powder packaging is formed into finished packaging bags after being packaged by automatic packaging machines or semi-automatic packaging machines. Some finished packaging bags need to be subsequently boxed, while some do not need to be boxed and are directly removed by robots for palletizing. However, when packaging the boxes, the unexpanded box board needs to be sucked and moved to the conveyor line first, and then the box board is sent to the unfolding station by the conveyor line for unfolding. However, due to the different sizes of the boxes, the sizes of the box boards are also different. The current vacuum suction device utilizes the lifting of the vacuum suction cup to absorb the four corners of the box board. The suction position is fixed and cannot be flexibly adjusted according to the size of the box board. Summary of the invention

[0004] To solve the above technical problems, the technical solution of the present invention is: a vacuum suction device for a packaging box plate, comprising a connecting frame, a connecting structure for fixing to the execution end of a manipulator is provided on the connecting frame, a first rotating shaft and a second rotating shaft parallel to each other are rotatably installed on the connecting frame, a main deflection force device for driving the first rotating shaft and the second rotating shaft to deflect synchronously in the opposite direction is provided on the connecting frame, two first mounting brackets and two second mounting brackets are fixedly installed on the first rotating shaft and the second rotating shaft respectively, the lower ends of the first mounting bracket and the second mounting bracket are hinged with suction cup mounting plates, angle adjustment structures for adjusting the angle of the suction cup mounting plates are provided between the first mounting bracket and the suction cup mounting plate and between the second mounting bracket and the suction cup mounting plate, and a buffered vacuum suction cup for sucking the packaging box plate is installed on the suction cup mounting plate.

[0005] As a preferred solution, the angle adjustment structure between the first mounting bracket and the suction cup mounting plate includes a secondary yaw cylinder, which is hinged between the first mounting bracket and the suction cup mounting plate, and the suction cup mounting plate is provided with a detection sensor for detecting whether there is a packaging box underneath.

[0006] As a preferred solution, the middle part of the suction cup mounting plate is hinged to the bottom of the first mounting bracket, the vacuum suction cup is installed on the suction cup mounting plate on one side of the first mounting bracket, and the auxiliary yaw cylinder is hinged to the first mounting bracket on the other side of the first mounting bracket.

[0007] As a preferred solution, a position sensor for detecting the upper end position of the vacuum suction cup is also installed on the suction cup mounting plate on the same side as the vacuum suction cup.

[0008] As a preferred solution, the main yaw force device includes a first main yaw cylinder and a second main yaw cylinder, and the first lever arm and the second lever arm are fixedly mounted on the first rotating shaft and the second rotating shaft. The two ends of the first main yaw cylinder are hinged on the first lever arm and the connecting frame, and the second main yaw cylinder is hinged on the second lever arm and the connecting frame.

[0010] As a preferred solution, the first mounting bracket is a rod-shaped structure and is respectively fixed at two ends of the first rotating shaft.

[0011] After adopting the above technical scheme, the effect of the present invention is as follows: since the packaging box plate vacuum suction device includes a connecting frame, the connecting frame is provided with a connecting structure for fixing with the execution end of the robot, the connecting frame is rotatably installed with a first rotating shaft and a second rotating shaft parallel to each other, the connecting frame is provided with a main deflection force device for driving the first rotating shaft and the second rotating shaft to deflect synchronously in the opposite direction, two first mounting brackets and two second mounting brackets are fixedly installed on the first rotating shaft and the second rotating shaft respectively, the lower ends of the first mounting bracket and the second mounting bracket are hinged with a suction cup mounting plate, and the first mounting bracket and the suction cup mounting plate, and the second mounting bracket are connected between the first mounting bracket and the suction cup mounting plate. An angle adjustment structure for adjusting the angle of the suction cup mounting plate is provided between the bracket and the suction cup mounting plate, and a buffered vacuum suction cup for sucking the packaging box plate is installed on the suction cup mounting plate; firstly, the first rotating shaft and the second rotating shaft are driven to rotate by the main deflection force device, so that the first mounting bracket and the second mounting bracket are synchronously deflected in the opposite direction, and the vacuum suction cups on the first mounting bracket and the second mounting bracket will be tilted at this time, and then the vacuum suction cups are adjusted to be horizontal by the angle adjustment structure to ensure accurate contact with the packaging box plate; the vacuum suction device can change the position of the vacuum suction cup to meet the vacuum suction requirements of different packaging box plates, and can also deflect and retract the vacuum suction cup to avoid.

[0012] Furthermore, since the angle adjustment structure between the first mounting bracket and the suction cup mounting plate includes a secondary yaw cylinder, the secondary yaw cylinder is hinged between the first mounting bracket and the suction cup mounting plate, and a detection sensor for detecting whether there is a packaging box underneath is provided on the suction cup mounting plate; the swing of the dishwashing mounting plate can be controlled by extending and retracting the guide rod of the secondary yaw cylinder, so that the suction cup mounting plate can be kept level according to the swing angle of the first mounting bracket, and at the same time the detection sensor can ensure that each time the packaging box plate is sucked up, it is stable and accurate.

[0013] Furthermore, since the middle part of the suction cup mounting plate is hinged to the bottom of the first mounting bracket, the vacuum suction cup is installed on one side of the suction cup mounting plate located on the first mounting bracket, and the auxiliary yaw cylinder is hinged to the first mounting bracket on the other side of the first mounting bracket; ensuring that the installation of the auxiliary yaw cylinder will not affect the installation of the vacuum suction cup, and the use is accurate and reliable.

[0014] In addition, a position sensor for detecting the upper end position of the vacuum suction cup is installed on the suction cup mounting plate on the same side as the vacuum suction cup; the vacuum suction cup will move upward during the suction process, so that the vacuum suction cup presses the packaging box plate and then draws air to ensure sealing during the extraction, and the position sensor ensures that the pressure is pressed into place.

[0015] Furthermore, since the main yaw force device includes a first main yaw cylinder and a second main yaw cylinder, the first rotating shaft and the second rotating shaft are both fixedly mounted with a first force arm and a second force arm, the two ends of the first main yaw cylinder are hinged on the first force arm and a connecting frame, and the second main yaw cylinder is hinged on the second force arm and a connecting frame; when the first rotating shaft and the second rotating shaft rotate, the first main yaw cylinder and the second main yaw cylinder will also deflect accordingly, so the hinged installation of the first main yaw cylinder and the second main yaw cylinder improves flexibility during use and ensures reliable deflection.

[0016] Since the first rotating shaft and the second rotating shaft are installed in the same way, two hinged fulcrums are arranged on the first rotating shaft between the connecting frames, and the first force arm is located between the two hinged fulcrums; the first mounting bracket is a rod-shaped structure and is respectively fixed at the two ends of the first rotating shaft; in this way, when the first rotating shaft is driven, the first mounting brackets located at the two ends of the first rotating shaft are stable in deflection.

[0025] Furthermore, the middle part of the suction cup mounting plate 6 is hinged to the bottom of the first mounting bracket 4, the vacuum suction cup 7 is installed on the suction cup mounting plate 6 on one side of the first mounting bracket 4, and the auxiliary yaw cylinder 9 is hinged to the first mounting bracket 4 on the other side of the first mounting bracket 4; ensure that the installation of the auxiliary yaw cylinder 9 will not affect the installation of the vacuum suction cup 7, and the use is accurate and reliable.

[0026] In this embodiment, a position sensor 11 for detecting the upper end position of the vacuum suction cup 7 is also installed on the suction cup mounting plate 6 on the same side as the vacuum suction cup 7; the vacuum suction cup 7 will move upward during the suction process, so that the vacuum suction cup 7 presses the packaging box plate and then draws air to ensure sealing during the suction, and the position sensor 11 ensures that it is pressed down into place. The position sensor 11 and the detection sensor 10 are respectively installed on one of the first mounting brackets 4 and the suction cup mounting plate 6 of the second mounting bracket 5, thereby ensuring the accuracy of suction while reducing the cost of use.
