[0055] Product packing is usually the last step in product production, and among the packaging materials used for product packing, corrugated paperboard is one of the most important packaging forms used for products due to its advantages such as good protection performance and low product cost. However, in the process of product packaging, it is necessary to first unfold the flat cardboard to form a carton. Currently, it is common to open and put the carton manually, or to use some clamps to assist manual work to open and put the carton faster, which leads to low efficiency of unpacking and high labor intensity.

[0056] Based on the above technical problems, an embodiment of the utility model is proposed. The embodiment of the utility model discloses a box opening fixture, which may include a support seat 1, a linear motion component 2, a suction cup component 3, a box opening drive component 4, a box opening piece 5 and an external expansion component 6, wherein the support seat 1 is mounted on the support device of the box opening machine. The linear motion component 2 is mounted on the support seat 1. The suction cup component 3 is mounted on the linear motion component 2 to absorb the packaging box. The box opening drive component 4 is mounted on the support seat 1, and the box opening piece 5 is rotatably connected to the box opening drive component 4. When the box opening drive component 4 is actuated, the box opening piece 5 is driven to rotate and press the packaging box to unfold the packaging box. The external expansion component 6 is mounted on the support seat 1 and is located below the linear motion component 2. The linear motion component 2 drives the packaging box to move downward and is embedded in the external expansion component 6. When the external expansion component 6 is actuated, the bottom plate of the packaging box is unfolded outward to carry out product boxing. Therefore, without manual intervention, the box opening fixture can realize automatic box packing and box nesting of the packaging box, thereby improving the box opening efficiency and reducing manual labor intensity.

[0057] Reference Figure 1-8 The embodiment of the utility model provides a box opening fixture, which may include a support seat 1, a linear motion component 2, a suction cup component 3, a box opening drive component 4, a box opening member 5 and an external expansion component 6. Among them:

[0058] The support seat 1 is installed on the support device of the carton opener, and the linear motion assembly 2 is installed on the support seat 1. The suction cup assembly 3 is installed on the linear motion assembly 2 to suck the packaging box. The carton opening drive assembly 4 is installed on the support seat 1, and the carton opening member 5 is rotatably connected to the carton opening drive assembly 4. When the carton opening drive assembly 4 is actuated, the carton opening member 5 is driven to rotate and press the packaging box to unfold the packaging box. The external expansion assembly 6 is installed on the support seat 1 and is located below the linear motion assembly 2. The linear motion assembly 2 drives the packaging box to move downward and is embedded in the external expansion assembly 6. When the external expansion assembly 6 is actuated, the bottom plate of the packaging box is expanded outward to perform product boxing. Therefore, the automatic packing and boxing of the packaging box can be realized by the carton opening fixture without manual intervention, thereby improving the carton opening efficiency and reducing the labor intensity.

[0059] In the embodiment of the utility model, the unpacking fixture is mainly used for unpacking and inserting product packaging boxes, and the unpacking fixture is installed on the support device of the unpacking machine, wherein the support device provides installation support for the unpacking fixture and other parts of the unpacking machine. In some embodiments, the support device may also include a structure such as a mechanical arm, so that the motion trajectory of the unpacking fixture installed on the support device can be controlled to adapt to the unpacking operation of product packaging boxes on different production lines.

[0060] The support base 1 supports the components included in the unpacking fixture, and the linear motion assembly 2 is used to output linear motion, so as to drive the suction cup assembly 3 installed on the linear motion assembly 2 to perform linear motion in the vertical direction (also called lifting motion). The suction cup assembly 3 may include a fixed suction cup 301 and a vacuum generator, and the vacuum generator is connected to the fixed suction cup 301 by air circuit, and the vacuum generator may be installed on the support base 1, or on the linear motion assembly 2. The suction cup assembly 3 can be used to adsorb the side of a flat product packaging box, so as to realize automatic unpacking of the product packaging box without causing surface damage or scratches on the product packaging box.

[0061] The unpacking drive assembly 4 and the unpacking piece 5 cooperate to unfold the product packaging box, wherein the unfolding can be understood as opening the flat product packaging box to form a hollow structure with product packaging space. This can facilitate the subsequent operation of putting the product into the box from top to bottom. Among them, the unpacking piece 5 is rotatably connected to the unpacking drive assembly 4, and the unpacking drive assembly 4 is mainly used to output rotational motion. Thereby, it is possible to drive the unpacking piece 5 to rotate in the direction of the product packaging box to press the side of the flat product packaging box and unfold the packaging box. In some embodiments, the unpacking piece 5 can be a block structure or a plate structure, so that the automatic unfolding of the product packaging box can be achieved by increasing the contact area between the unpacking piece 5 and the outer side of the product packaging box, while ensuring that the product packaging box will not be crushed.

[0062] The outward expansion component 6 is used to expand the bottom plate of the unfolded packaging box outward to avoid obstruction when the product is put into the box. The outward expansion component 6 can be installed on the support seat 1 in a detachable manner, and is located below the linear motion component 2. After the product packaging box is unfolded, the linear motion component 2 can drive the packaging box to move downward, so that the two side edges of the unfolded packaging box can be embedded in the outward expansion component 6. The embedding setting can enable the outward expansion component 6 to limit the two bottom plates at the bottom of the product packaging box, so that when the outward expansion component 6 is in motion, the limited bottom plates are driven to move away from each other, and then the product is put into the box.

[0063] In the embodiment of the utility model, the product may include but is not limited to household appliances such as air conditioner outdoor unit, rice cooker and washing machine. During the use of the unpacking fixture, the support device may be first moved so that the unpacking fixture is close to the packaging box to be unfolded, and then the suction cup assembly 3 is actuated to adsorb the packaging box, and then the support device is moved so that the unpacking fixture is located above the product to be packaged. During the movement of the support device, the carton can be unfolded synchronously. That is, the unpacking drive assembly 4 is actuated to drive the unpacking member 5 to rotate, and then the packaging box is pressed and touched so that the packaging box is forced to change from a flat shape to a rectangular parallelepiped shape, thereby realizing the unfolding of the packaging box. Then the linear motion assembly 2 is actuated so that the unfolded packaging box moves downward, and the two side edges of the packaging box are embedded in the external expansion assembly 6. Finally, the external expansion assembly 6 is actuated to pull the two side edges of the packaging box outward, and finally the support device is moved so that the packaging box with the edges expanded outward is set from top to bottom on the product to be packaged, thereby completing the automatic unpacking and boxing of the product, greatly improving the packaging efficiency of the product.

[0064] In summary, the embodiment of the utility model discloses a box opening fixture, which may include a support seat 1, a linear motion component 2, a suction cup component 3, a box opening drive component 4, a box opening piece 5 and an external expansion component 6, wherein the support seat 1 is mounted on the support device of the box opening machine. The linear motion component 2 is mounted on the support seat 1. The suction cup component 3 is mounted on the linear motion component 2 to suck the packaging box. The box opening drive component 4 is mounted on the support seat 1, and the box opening piece 5 is rotatably connected to the box opening drive component 4. When the box opening drive component 4 is actuated, the box opening piece 5 is driven to rotate and press the packaging box to unfold the packaging box. The external expansion component 6 is mounted on the support seat 1 and is located below the linear motion component 2. The linear motion component 2 drives the packaging box to move downward and is embedded in the external expansion component 6. When the external expansion component 6 is actuated, the bottom plate of the packaging box is unfolded outward to carry out product boxing. Therefore, without manual intervention, the box opening fixture can realize automatic box packing and box nesting of the packaging box, thereby improving the box opening efficiency and reducing manual labor intensity.

[0065] In an optional utility model embodiment, referring to Figure 1 , Figure 2 as well as Figure 3 As shown, the suction cup assembly 3 includes a fixed suction cup 301, wherein the number of the fixed suction cups 301 is at least three.

[0066] As a preferred embodiment, the number of the fixed suction cups 301 is at least three. Considering that three points determine a plane, when the contact area between the fixed suction cup 301 and the packaging box is small, the adsorption stability of the packaging box can be improved by distributing at least three fixed suction cups 301. In some embodiments, the number of the fixed suction cups 301 can be three; in other embodiments, the number of the fixed suction cups 301 is four. Those skilled in the art can determine the number of the fixed suction cups 301 based on the actual adsorption results of packaging boxes of different specifications, and no excessive restrictions are made here.

[0067] In an optional utility model embodiment, referring to Figure 1 , Figure 2 as well as Figure 3As shown, the linear motion assembly 2 may further include a second slide rail 201, a second slider 202, a connecting bracket 203 and a fourth linear motion output device 204, wherein the second slide rail 201 is fixed on the support seat 1 and is vertically arranged. The second slider 202 is slidably connected to the second slide rail 201. The connecting bracket 203 is fixed on the second slider 202, wherein the suction cup assembly 3 is distributed on the connecting bracket 203. The fourth linear motion output device 204 is fixed on the support seat 1, and the output shaft of the fourth linear motion output device 204 is fixedly connected to the connecting bracket 203 or the second slider 202, so as to drive the packaging box adsorbed by the suction cup assembly 3 to perform lifting motion through the fourth linear motion output device 204.

[0068] In the embodiment of the utility model, the linear motion assembly 2 may further include a second slide rail 201, a second slider 202, a connecting bracket 203 and a fourth linear motion output device 204. The second slider 202 is slidably connected to the second slide rail 201. The second slide rail 201 is vertically arranged and can be fixed to the support seat 1 by bolting, welding, etc. The vertical arrangement refers to being arranged parallel to the vertical direction, so that the second slider 202 can slide up and down along the second slide rail 201. The connecting bracket 203 is used to install the suction cup assembly 3. In the case where there are multiple fixed suction cups 301, multiple fixed suction cups 301 are distributed on the connecting bracket 203. The connecting bracket 203 is fixedly connected to the second slider 202. The fourth linear motion output device 204 is used to output linear motion, wherein the fourth linear motion output device 204 is fixed to the support seat 1, and the output shaft of the fourth motion output device is fixedly connected to the connecting bracket 203, or the output shaft of the fourth motion output device is fixedly connected to the second slider 202. Furthermore, the output shaft of the fourth motion output device is arranged parallel to the second slide rail 201, that is, the fourth motion output device is also arranged vertically. Thus, the fourth linear motion output device 204 can output linear motion to drive the connecting bracket 203 to perform lifting motion, and the packaging box adsorbed by the suction cup assembly 3 to perform lifting motion.

[0069] In some embodiments, when the output shaft of the fourth motion output device is arranged downward, when the output shaft of the fourth motion output device is extended, the suction cup assembly 3 is driven to perform a downward movement; when the output shaft of the fourth motion output device is retracted, the suction cup assembly 3 is driven to perform an upward movement.

[0070] In other embodiments, when the output shaft of the fourth motion output is arranged upward, when the output shaft of the fourth motion output is extended, the suction cup assembly 3 is driven to move upward; when the output shaft of the fourth motion output is retracted, the suction cup assembly 3 is driven to move downward.

[0071] In an optional utility model embodiment, referring to Figure 1 , Figure 2 as well as Figure 3 As shown, the unpacking fixture may further include a stopper 9 fixed on the support base 1, wherein the stopper 9 is located on a side of the packaging box away from the unpacking piece 5, so as to cooperate with the unpacking piece 5 and the suction cup assembly 3 to form a three-side limit for the packaging box.

[0072] In the embodiment of the utility model, the blocking member 9 is mainly used to block the other side of the packaging box (the side of the packaging box away from the opening member 5) when the opening member 5 unfolds the packaging box, so as to prevent the packaging box from being deformed when unfolding. Therefore, the three side limiting functions of the suction cup assembly 3, the opening member 5 and the blocking member 9 can ensure that the packaging box will not be deformed after unfolding. For example, when the opening member 5 is located on the left side of the packaging box, the blocking member 9 is located on the right side of the packaging box; for another example, when the opening member 5 is located on the right side of the packaging box, the blocking member 9 is located on the left side of the packaging box.

[0073] In some optional embodiments, the stopper 9 is a rod-shaped structure. The design of the rod-shaped structure can not only limit the packaging box, but also ensure the smoothness of the contact with the packaging box, thereby avoiding the formation of indentations or scratches on the packaging box. In other optional embodiments, the stopper 9 is a plate-shaped structure. In the case where the stopper 9 is a plate-shaped structure, a rounded chamfer can be set on the edge of the contact surface between the stopper 9 and the packaging box, thereby improving the contact smoothness between the stopper 9 and the packaging box. The plate-shaped stopper 9 can not only disperse the pressure force on the packaging box, but also increase the limiting area on the side of the packaging box. Thereby further improving the limiting effect on the packaging box.

[0074] In an optional utility model embodiment, referring to Figure 4 and Figure 5As shown, the unpacking drive assembly 4 may include an unpacking fixed plate 401, a third linear motion output device 402, a fixed block 403 and a rotating block 404, wherein the unpacking fixed plate 401 is located on the support seat 1. The third linear motion output device 402 is fixed on the unpacking fixed plate 401. The fixed block 403 is installed on the unpacking fixed plate 401 and is provided with a mounting groove. The rotating block 404 is embedded in the mounting groove and is rotatably connected to the fixed block 403, wherein the fixed block 403 is fixedly connected to the unpacking member 5 and is rotatably connected to the output shaft of the third linear motion output device 402, so that when the third linear motion output device 402 is extended or retracted, it drives the unpacking member 5 to perform a rotational movement close to or away from the packaging box.

[0075] In the embodiment of the utility model, the unpacking drive assembly 4 may further include an unpacking fixed plate 401, a third linear motion output device 402, a fixed block 403 and a rotating block 404. The third linear motion output device 402 is used to output linear motion, and the unpacking fixed plate 401 can be fixed to the support seat 1 by bolt connection, welding, etc. The third linear motion output device 402 is fixed to the unpacking fixed plate 401. The fixed block 403 is fixed to the unpacking fixed plate 401 by bolt connection or welding, and a mounting groove is provided on the fixed block 403. The mounting groove is used for the embedded setting of the rotating block 404, so that the projections of the fixed block 403 and the rotating block 404 on the horizontal plane have an overlapping area, and a rotating shaft is provided so that the fixed block 403 and the rotating block 404 are rotatably connected.

[0076] The fixed block 403 is fixedly connected to the box opening member 5, wherein the fixed block 403 can rotate around a vertically arranged rotation axis, which drives the box opening member 5 to form a synchronous rotation, so that the packaging box can be pressed and unfolded during the rotation process. The output shaft of the third linear motion output device 402 is rotationally connected to the fixed block 403, wherein the rotation axis between the output shaft of the third linear motion output device 402 and the fixed block 403 is arranged parallel to the rotation axis, so that when the third linear motion output device 402 is extended or retracted, the box opening member 5 can be driven to rotate closer to or away from the packaging box.

[0077] For example, when the third linear motion output device 402 is extended, the box opening member 5 performs a rotational motion close to the packaging box, and forms a pressure contact with the outer side surface of the packaging box during the rotation process, until the third linear motion output device 402 is fully extended, and the packaging box is unfolded. After the packaging box is nested, when the third linear motion output device 402 is retracted, the box opening member 5 performs a rotational motion away from the packaging box (or performs a reset motion) to perform the next cycle of box opening and nesting.

[0078] In another optional utility model embodiment, referring to Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the unpacking fixture may further include a first slider 7, a first slide rail 8, and a connecting piece, wherein the first slider 7 is located below the unpacking fixing plate 401 and is fixedly connected to the unpacking fixing plate 401.

The connecting piece is located on the unpacking fixing plate 401 and the support seat 1 to fix the unpacking fixing plate 401 and the support seat 1.

[0079] In the embodiment of the utility model, the unpacking fixture may further include a first slider 7, a first slide rail 8 and a connector, wherein the first slider 7 is located below the unpacking fixed plate 401 and is fixedly connected to the unpacking fixed plate 401. The first slide rail 8 is fixed to the support seat 1 and is arranged parallel to the output shaft of the third linear motion output device 402. Thus, when the first slider 7 is slidably connected to the first slide rail 8, the unpacking fixed plate 401 can be slid according to the size specifications of different packaging boxes to adjust the unpacking position of the unpacking member 5 relative to the packaging box. The connector may be located on the unpacking fixed plate 401 and the support seat 1 to fix the unpacking fixed plate 401 and the support seat 1. The connector may serve as an intermediate connector, so that the unpacking fixture can adapt to the automatic unpacking operation of packaging boxes of different sizes. The product applicability of the unpacking fixture is further improved.

[0080] In an optional utility model embodiment, referring to Figure 1 , Figure 7 as well as Figure 8As shown, the outward expansion assembly 6 includes a first outward expansion structure 61 and a second outward expansion structure 62, and the first outward expansion structure 61 and the second outward expansion structure 62 are respectively located at two opposite sides of the packaging box. The first outward expansion structure 61 includes a first pull claw 611 for embedding in the packaging box, and the second outward expansion structure 62 includes a second pull claw 621 for embedding in the packaging box, so that when the first pull claw 611 and the second pull claw 621 are in motion, the two bottom plates of the packaging box are driven to expand outward.

[0081] In the embodiment of the utility model, the outward expansion component 6 may include a first outward expansion structure 61 and a second outward expansion structure 62, wherein the first outward expansion structure 61 and the second outward expansion structure 62 are respectively located at two opposite sides of the packaging box, for example, the first outward expansion structure 61 is located at the rear side of the packaging box, and the second outward expansion structure 62 is located at the front side of the packaging box, wherein the side adsorbed by the suction cup assembly 3 is determined to be the rear side of the packaging box. A first pull claw 611 is provided on the first outward expansion structure 61, and a second pull claw 621 is provided on the second outward expansion structure 62. The first pull claw 611 cooperates with the first outward expansion structure 61 to form a first accommodating groove with an opening facing upward, and the second pull claw 621 cooperates with the second outward expansion structure 62 to form a second accommodating groove with an opening facing upward. Thus, when the linear motion assembly 2 drives the packaging box to move downward, the two bottom plates of the packaging box (two bottom plates on opposite sides of the four bottom plates forming the bottom of the folding packaging box) are respectively embedded in the first accommodating groove and the second accommodating groove, so that when the first outward expansion structure 61 and the second outward expansion structure 62 move, the carton bottom plate embedded in the first pull claw 611 and the second pull claw 621 are driven to expand outward. This can avoid affecting the product boxing operation when the carton bottom plate naturally hangs down. And the product boxing and box sealing can be automatically performed after the bottom plate expands outward, which improves the product packing efficiency and greatly reduces the labor intensity of manual labor.

[0082] In an optional utility model embodiment, referring to Figure 1 , Figure 2 as well as Figure 6 As shown, the first outward expansion structure 61 may also include a first linear motion output device 612, an outward expansion shaft 613 and a first outward expansion plate 614. The first linear motion output device 612 is hinged on the support seat 1. The outward expansion shaft 613 is rotatably connected to the support seat 1. The first outward expansion plate 614 is fixed to the outward expansion shaft 613 and is rotatably connected to the output shaft of the first linear motion output device 612, wherein the first pulling claw 611 is arranged on the end face of the first outward expansion plate 614 close to the packaging box, and when the first linear motion output device 612 is actuated, the first pulling claw 611 is driven to rotate so that the bottom plate of the packaging box is expanded outward.

In other words, the first linear motion output device 612 can rotate freely around the support seat 1. The outward expansion shaft 613 is rotatably connected to the support seat 1, wherein the rotatable connection can be achieved by a bearing seat. For example, bearing seats are respectively provided at both ends of the outward expansion shaft 613, the outward expansion shaft 613 is rotatably connected to the bearing seat, and the bearing seat is fixed to the support seat 1 by welding, bolt connection, etc.

[0084] When the first linear motion output device 612 is extended and retracted, the first linear motion output device 612 drives the first external expansion plate 614 to rotate a certain angle around the external expansion shaft 613. The first external expansion plate 614 is used to provide an assembly position for the first pull claw 611, and the first external expansion plate 614 is fixedly connected to the external expansion shaft 613, for example, the first external expansion plate 614 and the external expansion shaft 613 are welded and fixed. Therefore, when the first external expansion plate 614 is driven to rotate by the first linear motion output device 612, the first pull claw 611 is driven to rotate outwards by a certain angle, so that one bottom plate of the packaging box is expanded outwards.

[0085] For example, when the first linear motion output device 612 is in an extended state, the opening of the first accommodating groove is vertically upward. When the first linear motion output device 612 is in a retracted state, the opening of the first accommodating groove is set at an angle to the vertical direction, and the opening of the first accommodating groove is set toward the inside of the packaging box.

The second linear motion output device 623 is fixed to the fixing rod 622 and is arranged horizontally. The horizontal arrangement can be understood as the output shaft of the second linear motion output device 623 being arranged parallel to the horizontal direction, so that linear motion in the horizontal direction can be output. The second expansion plate 624 is used to provide an assembly position for the second pull claw 621, and the second expansion plate 624 is fixed to the output shaft of the second linear motion output device 623. Therefore, when the second linear motion output device 623 is actuated, the second pull claw 621 can be driven to perform a linear motion away from the packaging box, and the bottom plate located in the second accommodating groove can be pulled outward, so that the second bottom plate of the packaging box is unfolded outward.

[0089] In the embodiment of the utility model, the second linear motion output device 623 can be a three-axis cylinder. Since two guide shafts are added to the three-axis cylinder, the second linear motion output device 623 has a high anti-torsion and anti-lateral load capacity, and the linear motion precision is high. As a result, the supporting capacity and driving capacity of the output shaft of the second linear motion output device for the second outer expansion plate 624 can be improved.
