[0042] As shown in Figures 1-6 , the present embodiment first provides a fixing mechanism 1 of a packaging box, which is suitable for packaging boxes 100 that need to fix or lock the box body 101 and the cover body 102. In the present embodiment, a four-up box is taken as an example for illustration. As shown in Figure 7 and Figure 8 , the four-up box includes the box body 101 and the cover body 102. The box body 101 includes two first side plates 1011 oppositely arranged in a first direction (X direction) and two second side plates 1012 oppositely arranged in a second direction (Y direction), and the first side plates 1011 and the second side plates 1012 are separated from each other. The first direction can be the length direction of the four-up box, and the second direction can be the width direction of the four-up box, or vice versa. The first direction and the second direction are perpendicular to each other and perpendicular to the height direction of the four-up box. The cover body 102 includes eight adaptive side plates connected to each other, which are two first adaptive plates 1021, two second adaptive plates 1022 and four connecting adaptive plates 1023. Among them, the first adaptive plates 1021 and the second adaptive plates 1022 correspond to the positions of the first side plates 1011 and the second side plates 1012 respectively, and the connecting adaptive plates 1023 are used to connect the adjacent first adaptive plates 1021 and second adaptive plates 1022. After the bottle body is put into the box body 101, the cover body 102 is inserted and connected at the top of the box body 101 for packaging, and then the box body 101 and the cover body 102 are fixed together. Among them, the box body 101 and the cover body 102 are connected and fixed by fixing members or connecting members, which are generally manually fixed and operated, resulting in low efficiency of the packaging box 100, high labor cost and high labor intensity.

[0043] The fixing mechanism 1 of the packaging box provided by the embodiment of the present application is used for fixing the box body 101 and the cover body 102 of the packaging box 100 by automatically grabbing the fixing member or the connecting member, wherein the fixing member or the connecting member can be a buckle, the box body through hole 1013 can be provided on the first side plate 1011 and the second side plate 1012 respectively, and the cover body through hole 1024 corresponding to the box body through hole 1013 can be provided on the first adaptive plate 1021 and the second adaptive plate 1022 as an adaptive structure. In other embodiments, the fixing member can also be other structural members such as an elastic pin, and the embodiment takes the buckle as the fixing member, and takes the fixing member inserted into the box body through hole 1013 and the cover body through hole 1024 as an example to exemplarily describe the fixing mechanism 1 of the packaging box.

[0044] The fixing mechanism 1 of the packaging box provided by the embodiment of the present application comprises a mounting frame 11, a first driving member 12 and a grab head 13, the first driving member 12 is arranged on the mounting frame 11, the grab head 13 comprises a swing driving member 131 and a grab hand 132, the swing driving member 131 is arranged on the output end of the first driving member 12, and the grab hand 132 is arranged on the output end of the swing driving member 131; when the first driving member 12 drives the swing driving member 131 to a first moving position, the swing driving member 131 drives the grab hand 132 to a first swing angle position to grab the fixing member; and when the swing driving member 131 drives the grab hand 132 to a second swing angle position, the first driving member 12 drives the swing driving member 131 to a second moving position so that the fixing member is simultaneously clamped into the box body 101 and the cover body 102 to fix the box body 101 and the cover body 102.

[0045] As Figures 2-6 The fixing mechanism 1 of the packaging box provided by the present application can realize the switching of the grab hand 132 between the first moving position and the second moving position and the switching of the grab hand 132 between the first swing angle position and the second swing angle position by arranging the first driving member 12 and the swing driving member 131, so that the first driving member 12 drives the grab hand 132 to the first moving position and the first swing angle position to grab the fixing member, and then drives the grab hand 132 to the second swing angle position and the second moving position to clamp the fixing member into the box body 101 and the cover body 102 of the packaging box 100, thereby realizing the automatic fixing of the fixing member to the box body 101 and the cover body 102 without manual participation, and further improving the packaging efficiency of the packaging box 100 and reducing the packaging cost.

[0046] As Figure 2As shown, a plurality of first driving members 12 are arranged on the mounting frame 11 in sequence along the length direction (X direction) of the mounting frame 11, so that the plurality of packaging boxes 100 can be fixed simultaneously along the X direction, and the packaging efficiency of the packaging boxes 100 is improved. Further, the claws 13 are arranged in pairs along the second direction (Y direction), so that the two groups of first side plates 1011 and first fitting plates 1021 arranged in relative positions and the second side plates 1012 and second fitting plates 1022 arranged in relative positions can be fixed simultaneously, and the installation efficiency is high. The two claws 13 arranged in pairs can simultaneously and synchronously fix the packaging boxes 100, and the fixing member generates a relative force when contacting the packaging boxes 100, which is beneficial to the stable fixation of the packaging boxes 100. The two claws 13 arranged in pairs can be driven and controlled by two single-output first driving members 12 respectively, or can be controlled by one double-output first driving member 12, which is selected according to the actual structure.

[0047] In some embodiments, the claw 13 further comprises a swing mounting member 133 and a swing connecting member 134. The swing mounting member 133 is arranged at the output end of the first driving member 12, and the fixed end of the swing driving member 131 is rotatably arranged on the swing mounting member 133. The swing connecting member 134 is rotatably connected to the swing mounting member 133, the movable end of the swing driving member 131 is rotatably connected to the swing connecting member 134, and the gripper 132 is arranged on the swing connecting member 134. The telescopic movement of the movable end of the swing driving member 131 can drive the swing connecting member 134 to rotate, so that the gripper 132 can switch between the first swing angle position and the second swing angle position.

[0048] As shown in Figure 5 and Figure 6 The swing driving member 131 is taken as an example of a pneumatic cylinder. When the output end of the swing driving member 131 telescopes, the swing connecting member 134 rotates relative to the swing mounting member 133, and the swing connecting member 134 drives the gripper 132 to switch between the first swing angle position and the second swing angle position. In other embodiments, the swing driving member 131 can also be a motor. The swing connecting member 134 is rotatably connected to the swing mounting member 133 through a rotating shaft, and the output shaft of the motor directly drives the rotating shaft to rotate, so that the swing connecting member 134 can be driven and controlled between the first swing angle position and the second swing angle position. It can be understood that the swing mounting member 133 and the swing driving member 131 are respectively hinged to two different positions on the swing connecting member 134, so as to facilitate the rotating movement of the swing connecting member 134. Preferably, the swing driving member 131 is coaxially arranged with the gripper 132 for positioning.

[0049] In some embodiments, the grabber 13 further comprises a limiting member 136 arranged on the swing mounting member 133 close to one end of the swing connecting member 134, and the swing connecting member 134 can abut against the limiting member 136 when the grabber 132 rotates from the second swing angle position to the first swing angle position.

[0050] As shown in Figure 6 , the limiting member 136 is arranged on the swing mounting member 133 to limit the rotation angle of the swing connecting member 134, and can limit the swing connecting member 134 to rotate in one direction only. When the grabber 132 is located at the first swing angle position, the swing connecting member 134 abuts against the limiting member 136 to prevent the swing connecting member 134 from continuing to rotate, which is beneficial to limit the swing angle position of the grabber 132 to accurately grasp the fixing member. The limiting member 136 enables the swing connecting member 134 to rotate in one direction only from the first swing angle position to the second swing angle position, thereby enabling the two grabbers 13 arranged in pairs to rotate and fix relative to each other, and improving the packaging efficiency.

[0051] In some embodiments, the grabber 132 comprises a suction cup. The grabber 132 can adsorb the fixing member by vacuum adsorption, which is beneficial to the control of grasping and releasing, and the suction cup is made of elastic material, which can avoid damage to the fixing member and the packaging box 100. According to needs, the grabber 132 can be a plurality of suction cups arranged on the swing connecting member 134, which are used to fix the packaging box 100 by multiple fixing members at the same time. In other embodiments, the grabber 132 can also be a structure such as a clamping jaw having a grasping and releasing function, which is not limited to a suction cup.

[0052] In some embodiments, the grabber 13 further comprises a protection member 135 fixedly arranged on the swing connecting member 134, and the protection member 135 is provided with an accommodation space for accommodating at least part of the grabber 132.

[0053] As shown in Figure 6 , the protection member 135 is arranged at the end of the swing connecting member 134, and the protection member 135 is provided with an accommodation space and a through hole communicating with the accommodation space. The suction cup is arranged through the through hole, and at least part of the structure of the suction cup is located in the accommodation space to prevent the suction cup from being damaged. Specifically, the protection member 135 is a shell structure member, and the structure size of the protection member 135 is consistent with the end of the swing connecting member 134. The protection member 135 is detachably mounted on the swing connecting member 134.

[0054] In some embodiments, the first driving member 12 comprises a double-head cylinder, and two movable ends of the double-head cylinder are respectively connected to one grabber 13, so that the two grabbers 13 can move towards or away from each other in the second direction.

[0055] As shown in Figure 4As shown, the first driving member 12 adopts a double-head cylinder, two grab heads 13 can be installed simultaneously, and the movement of the two grab heads 13 can be easily controlled synchronously to simultaneously fix the opposite sides of the packaging box 100, improve the efficiency, and easily control the symmetry during fixing to ensure the stable fixing of the packaging box 100. Of course, in other embodiments, the first driving member 12 also adopts a double-output oil cylinder or a double-output motor to realize the synchronous movement of the two grab heads 13. The double-head cylinder can also be formed by combining two single-output cylinders to form a coaxial driving mechanism. The first driving member 12 and the swing driving member 131 are preferably linear driving mechanisms such as cylinders or oil cylinders, which are easy to control and install.

[0056] In some embodiments, the fixing mechanism 1 of the packaging box further comprises a connecting rod assembly 14, the connecting rod assembly 14 is hinged to the mounting frame 11, a plurality of first driving members 12 are arranged on the connecting rod assembly 14, and the connecting rod assembly 14 can be extended and contracted in the first direction to drive the plurality of first driving members 12 to move close to or away from each other in the first direction, and the first direction is perpendicular to the second direction.

[0057] As shown in Figure 2 and Figure 3 The connecting rod assembly 14 is arranged along the length direction of the mounting frame 11, a plurality of first driving members 12 can be installed in sequence to move synchronously to simultaneously fix a plurality of packaging boxes 100. One end of the connecting rod assembly 14 is hinged to the mounting frame 11, and when the connecting rod assembly 14 is extended and contracted, the other end drives the plurality of first driving members 12 to move close to or away from each other to adapt to the position of the packaging box 100 and the position of the fixing member. The extension and contraction of the connecting rod assembly 14 can be controlled mechanically or by a second driving member (not shown in the figure). The second driving member is configured to drive the extension and contraction of the connecting rod assembly 14. The second driving member can adopt a cylinder, an oil cylinder, and a motor, etc. The second driving member can be arranged at any one end of the connecting rod assembly 14 on the mounting frame 11. By pulling the first driving member 12 at the end or moving the connecting rod assembly 14, the connecting rod assembly 14 can be extended and contracted to move the remaining first driving members 12. By arranging the connecting rod assembly 14, the synchronous movement of the plurality of first driving members 12 can be realized by only one second driving member, the movement efficiency is improved, and the cost of the equipment is reduced.

[0058] In some embodiments, a plurality of second driving members can be arranged, and the plurality of second driving members are arranged one by one corresponding to the plurality of first driving members 12 to respectively drive the movement of the first driving members 12 in the first direction, so that the gripper 132 can move in the second direction between the first moving position and the second moving position to perform the fixing operation of the packaging box 100. When the second driving member is a plurality of second driving members, the connecting rod assembly 14 can be omitted.

[0059] In some embodiments, the linkage assembly 14 comprises a plurality of linkage units, each linkage unit comprising two linkages 141 cross-hingedly connected at a cross point, the corresponding linkages 141 of two adjacent linkage units are hingedly connected, and one first driving member 12 is hingedly connected at the cross point of each linkage unit.

[0060] As shown in Figure 3 each linkage unit comprises two equal-length linkages 141 cross-hingedly connected, the hinged positions of the two linkages 141 are cross points, the first driving member 12 is hingedly connected at the cross points, and the relative rotation of the two linkages 141 drives the position of the first driving member 12 to move. In two adjacent linkage units, the ends of the two linkages 141 in one linkage unit are hingedly connected to the first ends of the two linkages 141 in the other linkage unit, realizing the hinged connection of the plurality of linkage units in series. Through this structure, when the linkage assembly 14 is stretched or retracted, the plurality of first driving members 12 can be driven to move closer to or away from each other, realizing synchronous movement control.

[0061] In some embodiments, the fixing mechanism 1 of the packaging box further comprises a sliding rail 15 and a plurality of sliding blocks 16. The sliding rail 15 is arranged on the mounting frame 11 and is arranged along the first direction. The plurality of sliding blocks 16 are each slidingly connected to the sliding rail 15, and the plurality of first driving members 12 are connected to the plurality of sliding blocks 16 in one-to-one correspondence.

[0062] As shown in Figure 4 In order to reduce the load of the plurality of first driving members 12 on the linkage assembly 14, the plurality of first driving members 12 are slidingly installed on the guide rail on the mounting frame 11 through the sliding blocks 16, so as to bear the weight of the plurality of first driving members 12 through the mounting frame 11. In order to facilitate the installation and sliding of the first driving member 12, in this embodiment, the first driving member 12 is first installed on the sliding installation member 121, and then hingedly connected to the linkage assembly 14 through the sliding installation member 121. The two sides of the sliding installation member 121 are symmetrically provided with sliding connectors 122, the sliding connectors 122 are fixedly connected to the sliding blocks 16, the two sides of the mounting frame 11 along the Y direction are symmetrically provided with the sliding rails 15, and then the two ends of the first driving member 12 along the Y direction are slidingly installed on the mounting frame 11, so as to ensure the stable installation of the first driving member 12.
