[0002] With the rapid development of economy, the output and consumption of commodities also grow rapidly; therefore, the commodities have the process requirement of box packing and unpacking. The traditional box page opening method is to use manpower to open, which has the disadvantages of low efficiency and high labor cost. The most commonly used method at present still relies on box opening equipment.

[0003] Most of the existing box opening equipment uses mechanical arms or complex mechanical structures to complete the opening, and therefore has high use and maintenance costs.

[0004] In addition, the existing box opening equipment cannot be used for various box sizes, and therefore has poor versatility.

[0026] In order to explain the technical content and structural features of the present application in detail, the following further description is made in conjunction with the embodiments and the accompanying drawings.

[0027] Please refer to Figures 1-2 The flexible box opening device 100 of the present application comprises a first driving shaft 1, a second driving shaft 2, a third driving shaft 3, a first swing arm 4, a second swing arm 5 and a capturing assembly 6. The first swing arm 4 has a first end 41 and a second end 42, and the first driving shaft 1 is fixedly connected with the first end 41 of the first swing arm 4. The second swing arm 5 has a third end 51 and a fourth end 52, and the second driving shaft 2 is fixedly connected with the third end 51 of the second swing arm 5 and is movably connected with the second end 42 of the first swing arm 4 through a first bearing 21. The third driving shaft 3 is movably connected with the fourth end 52 of the second swing arm 5 through a second bearing (not shown in the drawing), and the third driving shaft 3 is fixedly connected with the capturing assembly 6. When the first driving shaft 1 is driven to rotate, the first swing arm 4 swings around the central axis of the first driving shaft 1. For example, when the first driving shaft 1 rotates clockwise, the first swing arm 4 swings clockwise around the central axis of the first driving shaft 1; when the first driving shaft 1 rotates counterclockwise, the first swing arm 4 swings counterclockwise around the central axis of the first driving shaft 1. When the second driving shaft 2 is driven to rotate, the second swing arm 5 swings around the central axis of the second driving shaft 2. For example, when the second driving shaft 2 rotates clockwise, the second swing arm 5 swings clockwise around the central axis of the second driving shaft 2; when the second driving shaft 2 rotates counterclockwise, the second swing arm 5 swings counterclockwise around the central axis of the second driving shaft 2. When the third driving shaft 3 is driven to rotate, the capturing assembly 6 rotates around the central axis of the third driving shaft 3. For example, when the third driving shaft 3 rotates clockwise, the capturing assembly 6 swings clockwise around the central axis of the third driving shaft 3; when the third driving shaft 3 rotates counterclockwise, the capturing assembly 6 swings counterclockwise around the central axis of the third driving shaft 3. More specifically, as follows:

[0028] Please continue to refer to Figure 1 and Figure 2The first swing arm 4 is further provided with a first driving mechanism 7 for driving the second driving shaft 2 to rotate. Specifically, the first driving mechanism 7 comprises a first driver 71 and a first transmission assembly 72. A part of the first transmission assembly 72 is connected with the output end of the first driver 71, and the other part of the first transmission assembly 72 is fixedly connected with the second driving shaft 2. For example, the first driver 71 is a first cylinder which is mounted on the first swing arm 4. The specific structure and principle of the first cylinder are known to those skilled in the art, and thus will not be described here. Of course, in other embodiments, the first driver 71 can also be a motor, and thus is not limited to this. Specifically, the first transmission assembly 72 comprises a first synchronous wheel 721, a first idler wheel 722, a first belt 723, and a first belt connecting block 724. The first idler wheel 722 is sleeved on the first driving shaft 1 and is provided with a movable bearing (not shown in the figure) between the first driving shaft 1 and the first idler wheel 722, so that when the first driving shaft 1 rotates, the first idler wheel 722 will not rotate. The first synchronous wheel 721 is sleeved on the second driving shaft 2, the first belt 723 is sleeved on the first synchronous wheel 721 and the first idler wheel 722 at the same time, and the first belt connecting block 724 is connected with the first belt 723 and the output end of the first driver 71 at the same time. For example, when the first driving mechanism 7 works, the first cylinder extends to drive the first belt connecting block 724 to move, thereby driving the first belt 723 to rotate clockwise, thereby driving the first synchronous wheel 721 to rotate clockwise, thereby driving the second driving shaft 2 to rotate clockwise. It can be understood that when the second driving shaft 2 rotates clockwise, the second swing arm 5 rotates clockwise. Conversely, when the first cylinder retracts, it drives the first belt connecting block 724 to move, thereby driving the first belt 723 to rotate counterclockwise, thereby driving the first synchronous wheel 721 to rotate counterclockwise, thereby driving the second driving shaft 2 to rotate counterclockwise. It can be understood that when the second driving shaft 2 rotates counterclockwise, the second swing arm 5 rotates counterclockwise.

[0029] Please continue to refer to Figure 1 and Figure 2The second swing arm 5 is further provided with a second driving mechanism 8 for driving the third driving shaft 3 to rotate. The second driving mechanism 8 comprises a second driver 81 and a second transmission assembly 82. A part of the second transmission assembly 82 is connected with the output end of the second driver 81, and another part of the second transmission assembly 82 is fixedly connected with the third driving shaft 3. For example, the second driver 81 is a second cylinder which is mounted on the second swing arm 5. Of course, in other embodiments, the second driver 81 can be an electric motor, and is not limited thereto. Specifically, the second transmission assembly 82 comprises a second synchronous wheel 821, a second idler wheel 822, a second belt 823 and a second belt connecting block 824. The second idler wheel 822 is sleeved on the second driving shaft 2 and is provided with a first bearing (not shown in the figure) between the second driving shaft 2, so that the second driving shaft 2 does not rotate when the second driving shaft 2 rotates. The second synchronous wheel 821 is sleeved on the third driving shaft 3, the second belt 823 is sleeved on the second synchronous wheel 821 and the second idler wheel 822, and the second belt connecting block 824 is connected with the second belt 823 and the output end of the second driver 81. For example, when the second driving mechanism 8 works, the second cylinder extends to drive the second belt connecting block 824 to move, so as to drive the second belt 823 to rotate clockwise, thereby driving the second synchronous wheel 821 to rotate clockwise, and driving the third driving shaft 3 to rotate clockwise. It can be understood that when the third driving shaft 3 rotates clockwise, the capturing assembly 6 rotates clockwise. Conversely, the second cylinder retracts to drive the second belt connecting block 824 to move, so as to drive the second belt 823 to rotate counterclockwise, thereby driving the second synchronous wheel 821 to rotate counterclockwise, and driving the third driving shaft 3 to rotate counterclockwise. It can be understood that when the third driving shaft 3 rotates counterclockwise, the capturing assembly 6 rotates counterclockwise.

[0030] Please refer to Figures 1-2 In this embodiment, the capturing assembly 6 is a vacuum suction assembly. Of course, in other embodiments, when the box body is provided with a handle or a buckle body or the like, the capturing assembly 6 is a grabbing assembly; or when the box body is a magnetic material, the capturing assembly 6 can be an electromagnet assembly, and the capturing assembly 6 is not limited thereto.

[0031] Please continue to refer to Figures 1-2 Specifically, the vacuum suction assembly comprises a suction nozzle mounting disc 61 and a plurality of suction nozzles 62. The suction nozzle mounting disc 61 is connected with the third driving shaft 3. Specifically, the suction nozzle mounting disc 61 is provided with a hinged seat 611, and the hinged seat 611 is provided with a mounting hole connected with the third driving shaft 3. The suction nozzles 62 are four in number and are spaced apart and mounted around the suction nozzle mounting disc 61. Of course, in other embodiments, the number of the suction nozzles 62 can be three, five, six or eight, and is not limited thereto.

[0032] Preferably, in this embodiment, the flexible box-opening device 100 of the present invention further includes a first limiting member 9 that limits the maximum rotation angle of the second swing arm 5. Specifically, the first limiting member 9 is installed on the second end 42 of the first swing arm 4. For example, in this embodiment, the first limiting member 9 limits the maximum angle of clockwise rotation of the second swing arm 5. That is, when the second swing arm 5 rotates clockwise to abut against the first limiting member 9, this is the maximum clockwise swing angle of the second swing arm 5.

[0033] Preferably, in this embodiment, the flexible unpacking device 100 of the present invention further includes a second limiting member 10 that limits the maximum rotation angle of the capture component 6. Specifically, the second limiting member 10 is mounted on the capture component 6, specifically on the nozzle mounting plate 61. For example, in this embodiment, the second limiting member 10 limits the maximum clockwise rotation angle of the capture component 6. That is, when the capture component 6 rotates clockwise until the second limiting member 10 abuts against the second swing arm 5, this is the maximum clockwise rotation angle of the capture component 6.

[0034] Combined with appendix Figure 3 and appendix Figure 6 The working principle of the flexible box-opening device 100 of the present invention will be explained as follows:

[0035] Please see Figure 3 This is the initial state of the flexible box-opening device 100 of the present invention. At this time, the first cylinder retracts, and the second swing arm 5 is at its maximum stroke position in the counterclockwise direction; the second cylinder extends, and the suction cup axis of the capturing component 6 is perpendicular to the direction of the second swing arm 5. In this state, the flexible box-opening device 100 is at its retracted limit position, does not interfere with the surrounding space of the box, and provides a working range for loading and unloading boxes.

[0036] Please see Figure 4 The flexible box-opening device 100 of the present invention operates from the initial state to state two. At this time, the first cylinder extends, driving the second swing arm 5 to rotate clockwise until the capturing component 6 is almost parallel to the box flaps. The suction cup of the capturing component 6 absorbs the parallel error between the box flaps and the suction cup using its own elastic margin, so that the suction cup can stably capture the box flaps.

[0037] Please see Figure 5 The flexible box-opening device 100 of the present invention operates from state two to state three. After the suction cup captures the box flap, the first cylinder and the second cylinder are disconnected from the air supply, and both the first cylinder and the second cylinder are in a relaxed and powerless state; at this time, the first drive shaft 1 rotates clockwise, thereby driving the first swing arm 4 to swing clockwise around the central axis of the first drive shaft 1. Since the suction cup is holding the flap, the pivot point of the flap is the support point, so the second swing arm 5 rotates counterclockwise around the axis of the second drive shaft 2; the capturing component 6 rotates counterclockwise.

[0038] Please refer to Figure 6 The flexible box opening device 100 of the present application runs from state three to state four. The first driving shaft 1 continues to rotate clockwise until the second swing arm 5 is perpendicular to the box flap; at this time, it is a critical boundary point, the second swing arm 5 and the capture assembly 6 are not enough power to continue to rotate counterclockwise, at this time, the first cylinder and the second cylinder start to contract to drive the second swing arm 5 to continue to rotate counterclockwise, drive the capture assembly 6 to continue to rotate counterclockwise, until the box flap is completely opened.

[0039] It can be understood that the rotating power of the first driving shaft 1 comes from the outside.

[0040] Please refer to Figure 7 It is shown that the box is a rectangular box, and four flaps are provided at each end, that is, when four flaps need to be opened, four sets of flexible box opening devices 100 of the present application can be provided. The rotating direction of the left flap and the right flap is opposite, therefore, the rotating direction of the corresponding flexible box opening device 100 is also opposite. Similarly, the rotating direction of the upper flap and the lower flap corresponding to the flexible box opening device 100 is opposite.

[0041] Compared with the prior art, the flexible box opening device 100 of the present application cooperates with the first driving shaft 1, the second driving shaft 2, the third driving shaft 3, the first swing arm 4, the second swing arm 5 and the capture assembly 6, the second driving shaft 2 can drive the rotation of the second swing arm 5, the third driving shaft 3 can drive the swing of the capture assembly 6, and the first driving shaft 1 can drive the swing of the whole device; the second driving shaft 2 can be movably connected with the first swing arm 4 and fixedly connected with the second swing arm 5; the third driving shaft 3 can be movably connected with the second swing arm 5 and fixedly connected with the capture assembly 6; when the second driving shaft 2 and the third driving shaft 3 are not driven, when the capture assembly 6 captures the flap, through the rotation of the first driving shaft 1, the second swing arm 5 and the capture assembly 6 can be driven to rotate at the same time. The flexible box opening device 100 of the present application has compact and exquisite structure, and greatly reduces the use cost. When multiple flaps need to be opened, only one flexible box opening device 100 of the present application needs to be provided on the outside of each flap, and only the opening sequence of each flap needs to be controlled. Therefore, the flexible box opening device 100 of the present application can be suitable for different opening requirements and different box structures, and can complete efficient opening operation at low cost.

[0042] The above only discloses the preferred embodiment of the present application, and cannot limit the scope of the right of the present application, therefore, the equivalent changes made according to the claims of the present application all belong to the scope covered by the present application.
