[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the embodiments of the present invention.

[0049] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, in the embodiments of the present invention, descriptions such as "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the embodiments of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0051] In the embodiments of the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0052] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the embodiments of the present invention.

[0053] With the rapid development of technology, electronic products have become an indispensable part of people's lives and work. During the production process of electronic products, packaging plays a vital role in product protection. After placing the product in the bag, the bag opening often needs to be bent to ensure product safety and compactness. Currently, bending electronic product bags primarily relies on manual labor. The repetitive bending process, performed over long periods of time, can easily lead to worker fatigue, hinder production progress, and reduce efficiency. Furthermore, manual bending forces and angles are difficult to maintain consistently, resulting in inconsistent bending results and impacting product appearance and protective performance.

[0054] In view of this, an embodiment of the present invention proposes a bag folding mechanism and a bag folding and packing device, wherein the bag folding clamping assembly is provided to clamp the target product, and the bending assembly performs a first bend on the bag opening of the packaging bag of the target product clamped by the bag folding clamping assembly. It can be understood that the bending assembly bends the bag opening of the packaging bag from downward to horizontal, and the bending assembly is supported below the bag opening of the packaging bag. At this time, the bag folding clamping drive assembly drives the bag folding clamping assembly to move toward the workbench, and the bag opening of the packaging bag is blocked by the bending assembly and continues to bend until it is bent to a second predetermined angle. The bag opening of the packaging bag changes from a horizontal state to an upward state, thereby realizing automatic bending of the packaging bag of the target product, saving manpower and improving work efficiency. Moreover, the consistency of the bending force and bending angle each time can be improved, and the bag folding effect or packaging quality stability of the packaging bag is higher.

[0055] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0056] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a bag folding mechanism for bending the bag opening of a packaging bag containing a target product. The bag folding mechanism 400 includes:

[0057] Workbench 410;

[0058] The bag folding clamping assembly 420 is movably disposed above the workbench 410 and is capable of clamping or releasing the target product. The bag folding clamping assembly 420 may be a clamp structure commonly used in the market and is not limited here. Optionally, after the bag folding clamping assembly 420 clamps the target product, the opening of the packaging bag placed on the outside of the target product is facing downward.

[0059] A bending assembly 430 is movably disposed on one side of the bag folding and clamping assembly 420 for bending the bag opening of the packaging bag;

[0060] The bag folding and gripping drive assembly 440 drives the bag folding and gripping assembly 420. After the bending assembly 430 bends the bag opening to a first predetermined angle, the bag opening is horizontal. The bag folding and gripping drive assembly 440 then moves toward the workbench 410 so that the bending assembly 430 bends the bag opening to a second predetermined angle, the bag opening facing upward. Optionally, the bag folding and gripping drive assembly 440 may be a pneumatic cylinder or an electric cylinder, etc., which is not limited here.

[0061] In the technical solution adopted in this embodiment, the folding bag clamping assembly 420 is provided to clamp the target product, and the bending assembly 430 performs a first bend on the bag opening of the target product clamped by the folding bag clamping assembly 420. It can be understood that the bending assembly 430 bends the bag opening of the bag from downward to horizontal, and the bending assembly 430 is supported below the bag opening of the bag. At this time, the folding bag clamping drive assembly 440 drives the folding bag clamping assembly 420 toward the workbench 410. The bag opening of the bag is blocked by the bending assembly 430 and continues to bend until it is bent to a second predetermined angle. The bag opening of the bag changes from a horizontal state to an upward state, thereby achieving automatic bending of the target product's bag, saving manpower and improving work efficiency.

[0062] In one embodiment of the present invention, referring to Figure 3 , the bending assembly 430 includes:

[0063] Folding rod 431;

[0064] A first bending drive structure 432 is drivingly connected to the folding rod 431 to drive the folding rod 431 toward or away from the folding bag clamping assembly 420; and

[0065] The second bending drive structure 433 connects the first bending drive structure 432 and the folding rod 431 . The second bending drive structure 433 drives the folding rod 431 to drive the folding rod 431 to bend the bag opening of the packaging bag to a first predetermined angle.

[0066] Specifically, the folding assembly 430 includes a folding rod 431, a first folding drive structure 432, and a second folding drive structure 433. The first folding drive structure 432 is disposed on the workbench 410 and is drivably connected to the second folding drive structure 433, which in turn is drivably connected to the folding rod 431. It will be appreciated that one end of the folding rod 431 is connected to the second folding drive structure 433, and the other end of the folding rod 431 extends toward the bag folding and gripping assembly 420. After the bag folding clamping assembly 420 clamps the target product, the first bending drive structure 432 drives the second bending mechanism and the folding rod 431 to move toward the target product, so that the end of the folding rod 431 away from the first bending drive structure 432 is located on one side of the bag opening (the left or right side of the bag). Then, the second bending drive structure 433 drives the folding rod 431 to move horizontally. The folding rod 431 abuts one side of the bag opening and drives the bag opening to bend horizontally until the bag opening is horizontal. At this time, the folding rod 431 abuts below the bag opening. Then, the bag folding clamping drive assembly 440 drives the bag folding clamping assembly 420 to move toward the workbench 410, that is, to move downward in the vertical direction. The bag opening of the bag will bend upward under the blocking action of the folding rod 431 until the bag opening is facing upward. In this manner, the folding rod 431, the first bending drive structure 432, the second bending drive structure 433, and the bag folding and gripping drive assembly 440 cooperate to bend the target product's packaging bag from downward to upward, and then the box packing and gripping assembly 520 grips the bent target product. At this point, the box packing and gripping assembly 520 grips the opening of the bent packaging bag, keeping it facing upward.

[0067] In one embodiment of the present invention, the bag folding clamping assembly 420 clamps two target products at a time, and the bag folding mechanism 400 further includes a separation assembly 450, which is disposed on one side of the bag folding clamping assembly 420 and is used to separate the bag openings of the packaging bags of the two target products to a predetermined distance.

[0068] Specifically, the bag folding and gripping assembly 420 grips two target products at a time, and the bending assembly 430 can simultaneously bend the packaging bags of the two target products, thereby improving bag folding efficiency. When the bag folding and gripping assembly 420 grips two target products at a time, the openings of the packaging bags of the two target products are abutted together. To this end, this embodiment also includes a separation assembly 450. The separation assembly 450 can separate the openings of the packaging bags of the two target products, facilitating the movement of the folding rod 431 between the openings of the two packaging bags, thereby bending the openings of the packaging bags.

[0069] In one embodiment of the present invention, referring to Figure 4 , the separation assembly 450 includes:

[0070] Suction cup 451, each target product is provided with at least one suction cup 451; and

[0071] The separation driving structure 452 drives the multiple suction cups 451 to separate the bag openings of the two packaging bags sucked by the multiple suction cups 451.

[0072] Specifically, the separation component 450 includes a suction cup 451 and a separation drive structure 452. The separation drive structure 452 drives the connection suction cup 451, and can drive the suction cup 451 to move toward or away from the target product. When moving toward the target product, the suction cup 451 can contact the packaging bag of the target product, thereby sucking the packaging bag. When moving away from the target product, it drives the bag opening of the packaging bag to move synchronously, so that there is a gap between the bag openings of the packaging bags of the two target products, making it convenient for the folding rod 431 to extend between the two packaging bags and bend the bag openings of the packaging bags. Optionally, each target product is respectively provided with one or more suction cups 451, and the suction cups 451 of the two target products are arranged on the side of the two target products facing away from each other. This can improve the stability of the suction of the suction cup 451 and prevent interference with the bending action of the folding rod 431. In one embodiment, the separation drive structure 452 can be a bidirectional screw that can synchronously drive the suction cups 451 of the two target products to move, and the structure is simpler.

[0073] In one embodiment of the present invention, the separation drive structure 452 includes a first separation cylinder and a second separation cylinder arranged at intervals, the first separation cylinder drives and connects a part of the multiple suction cups 451 and corresponds to one of the two target products, and the second separation cylinder drives and connects another part of the multiple suction cups 451 and corresponds to the other of the two target products.

[0074] Specifically, the separation drive structure 452 includes a first separation cylinder and a second separation cylinder. The first separation cylinder is used to drive the suction cup 451 corresponding to the first target product, and the second separation cylinder is used to drive the suction cup 451 corresponding to the second target product. In other words, the suction cups 451 corresponding to the two target products are driven by different separation cylinders, which can achieve independent control of the suction cup 451 corresponding to each target product, which is more convenient.

[0075] In one embodiment of the present invention, the workbench 410 is provided with a cache position, and the bag folding clamping driving component 440 drives the bag folding clamping component 420 to move toward the cache position to place the target product in the cache position. The cache position is provided to temporarily store the target product after the packaging bag is bent, which is convenient for the box clamping component 520 to clamp; Figure 2The bag folding mechanism 400 further includes a clamping structure 460, disposed on one side of the buffering position, for clamping the opening of the packaging bag, which has been bent to the second predetermined angle, against the side of the target product. It will be appreciated that before the folding rod 431 returns to its original position, the clamping structure 460 abuts the opening of the packaging bag, causing it to rest against the side of the target product. Due to the abutment of the clamping structure 460, the opening of the packaging bag remains facing upward. In other words, after the target product is placed in the buffering position, the clamping structure 460 first abuts the opening of the packaging bag. Then, the folding rod 431, driven by the first bending drive structure 432, returns to its initial position, separating from the opening of the packaging bag. This prevents the opening of the packaging bag from spontaneously bending under the action of gravity after the folding rod 431 returns to its original position. Optionally, the buffering position includes a clearance hole that allows the case clamping assembly 520 to clear the case clamping assembly 520, allowing it to clamp the target product in the buffering position.

[0076] In one embodiment of the present invention, the abutting structure 460 includes:

[0077] A clamping block movably disposed on one side of the buffer position; and

[0078] The abutting driving member is connected to the clamping block to drive the clamping block to move toward or away from the cache position.

[0079] Specifically, the abutment structure 460 includes a clamping block and a abutment driver. The abutment driver is operatively connected to the clamping block, driving the clamping block toward the target product, thereby abutting the opening of the packaging bag. Optionally, the abutment driver may be a pneumatic cylinder or an electric cylinder, which is not limited here.

[0080] In one embodiment of the present invention, the bag folding mechanism 400 further includes a bag folding linear drive assembly, which is drivably connected to the bag folding gripping drive assembly 440. Thus, the bag folding linear drive assembly can drive the bag folding gripping assembly 420 to move, placing the target product in the buffer position or ensuring that the case packing gripping assembly can grip the target product in the buffer position.

[0081] In one embodiment of the present invention, the bag folding and clamping drive assembly 440 includes:

[0082] A bag folding cylinder is located above the workbench 410; and

[0083] The mounting plate, the bag folding electric cylinder and the mounting plate are driven and connected, and the bag folding clamping component 420 is arranged on the mounting plate.

[0084] Specifically, the bag folding clamping drive assembly 440 includes a bag folding electric cylinder and a mounting plate. The bag folding electric cylinder is connected to the bag folding linear drive assembly, the mounting plate is connected to the bag folding cylinder, and the bag folding clamping assembly 420 is installed on the mounting plate. In this way, the bag folding cylinder can drive the bag folding clamping assembly 420 to move closer to or away from the workbench 410.

[0085] In one embodiment of the present invention, two groups of bag folding and gripping assemblies 420 are provided. The two groups of bag folding and gripping assemblies 420 are spaced apart along the length of the mounting plate, and each group of bag folding and gripping assemblies 420 is provided with a corresponding group of bending assemblies 430. This allows for simultaneous bending of two groups of packaging bags, or two target products, significantly improving bag folding efficiency.

[0086] To achieve the above purpose, refer to Figure 1 The present invention provides a bag folding and packing device, which includes the bag folding mechanism 400 described above. Specifically, the specific structure of the bag folding mechanism 400 is similar to that of the above embodiment. Since the bag folding and packing device adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.

[0087] The target product is typically placed in a packaging bag before being boxed. Currently, electronic product packaging boxes on the market are typically made of paper or plastic. The cavity within the box is easily deformed, resulting in a smaller cavity. This can scratch the glossy surface when the product is packed, affecting the product's appearance and resulting in poor quality. Because the product is already bagged and boxed, scratches are invisible. Damaged products could be sold to customers, negatively impacting their user experience.

[0088] To this end, in one embodiment of the present invention, referring to Figure 1 The bag folding and packing device further includes a packing mechanism 500 for packing the target product into the packaging box. The target product has a long side and a short side. It is understood that the existing target product is usually a cube with adjacent long sides and short sides, that is, two long sides and two short sides that are oppositely arranged. There are multiple cavities in the packaging box. It is understood that a knife card is provided inside the packaging box to separate the packaging box into multiple independent cavities, and at least one target product can be placed in each cavity. Figure 10 , the packing mechanism 500 includes:

[0089] The packing drive assembly 510 can be a robot or a three-axis moving module, which is not limited here;

[0090] The packing clamping assembly 520 is connected to the packing drive assembly 510 to drive the packing clamping assembly 520 to move. It is understood that the packing clamping assembly 520 can be driven by the packing drive assembly 510 to move to the top of the cavity of the packaging box, thereby placing the target product into the cavity. Optionally, the packing clamping assembly 520 can be a clamp commonly used in the market, which is not limited here; and

[0091] The carton expansion assembly 530 is connected to the carton clamping assembly 520. When the carton clamping assembly 520 releases the target product above the cavity, the carton expansion assembly 530 extends into the cavity to open the cavity so that the target product falls into the cavity. It is understandable that the carton expansion assembly 530 is connected to the carton clamping assembly 520. When the carton clamping assembly 520 releases the target product, the carton expansion assembly 530 can abut against the inner wall of the cavity, thereby expanding and enlarging the cavity. When the target product is placed in the cavity, it will not come into contact with the inner wall of the cavity. This prevents the high-gloss surface of the target product from being scratched. In one embodiment, the carton expansion assembly 530 can be an expansion rod, or a combination of a cylinder and an expansion rod, which is not limited here.

[0092] In the technical solution adopted in this embodiment, the case clamping assembly 520 is provided to clamp or release the target product. The case driving assembly 510 drives the case clamping assembly 520 to move above the mold cavity and the case expansion assembly 530 extends into the mold cavity. When the case clamping assembly 520 releases the target product, the case expansion assembly 530 moves synchronously with the case clamping assembly 520 and abuts against the inner wall of the mold cavity, thereby expanding and enlarging the mold cavity. The target product released from the case clamping assembly 520 will not contact the inner wall of the mold cavity during the falling process, thereby preventing the mold cavity from scratching the high-gloss surface of the target product and improving the appearance yield of the target product.

[0093] In one embodiment of the present invention, referring to Figure 10 , the box clamping assembly 520 includes:

[0094] A first boxing clamp 521 is used to clamp the long side of the target product;

[0095] The second cartoning clamper 522 is used to clamp the short side of the target product. The cartoning driving component 510 drives and connects the first cartoning clamper 521 and the second cartoning clamper 522 . The cartoning expansion component 530 is connected to the second cartoning clamper 522 .

[0096] Typically, the target product is a cube structure having two relative long sides and two relative short sides. To this end, in this embodiment, the boxing clamping assembly 520 includes a boxing first clamp 521 and a boxing second clamp 522 that are independently arranged, wherein the boxing first clamp 521 is used to clamp the two long sides of the target product, and the boxing second clamp 522 is used to clamp the two short sides of the target product. The boxing first clamp 521 and the boxing second clamp 522 are both connected to the boxing drive assembly 510 and can move under the drive of the boxing drive assembly 510. The boxing expansion assembly 530 is connected to the boxing second clamp 522. When the target product moves to the top of the cavity, the boxing second clamp 522 releases the short sides of the target product, the boxing expansion assembly 530 expands the cavity, and the boxing first clamp 521 keeps clamping the long sides of the target product. After the mold cavity is expanded to a predetermined extent by the carton expansion assembly 530, the first carton clamp 521 releases the long side of the target product, allowing it to fall into the mold cavity. This prevents the target product from falling during the mold cavity expansion process, thereby preventing the target product's high-gloss surface from being scratched due to incomplete expansion.

[0097] In one embodiment of the present invention, referring to Figure 10 , the packing clamping assembly 520 also includes a packing fixture drive structure 523, the packing drive assembly 510 drives the connection packing fixture drive structure 523, and the packing fixture drive structure 523 and the packing first clamp 521 drive connection so that the packing first clamp 521 moves toward or away from the cavity. In this way, by setting the packing fixture drive structure 523, the packing first clamp 521 can be driven to move toward the cavity, and the target product is placed in the cavity, thereby improving the reliability and stability of the target product being placed in the cavity, and can further prevent the target product from contacting the inner wall of the cavity, thereby avoiding scratches on the target product. It is understandable that when the packing expansion assembly 530 completes the expansion of the cavity, the packing fixture drive structure 523 drives the packing first clamp 521 to move close to the cavity, thereby accurately placing the target product into the cavity. In one embodiment, the packing fixture drive structure 523 can be a cylinder or an electric cylinder, etc., which is not limited here. In this embodiment, the cartoning drive assembly 510 drives and connects the cartoning clamp drive structure 523 and the cartoning second clamper 522 , that is, the cartoning first clamper 521 is connected to the cartoning drive assembly 510 via the cartoning clamp drive structure 523 .

[0098] In one embodiment of the present invention, the first clamper 521 for packaging includes:

[0099] Two first clamping jaws for packing are provided opposite to each other; and

[0100] The first clamping cylinder for packing, the packing drive assembly 510 drives the connection to the packing fixture drive structure 523, the packing fixture drive structure 523 drives the connection to the first clamping cylinder for packing, the first clamping cylinder for packing drives the connection to the two first clamping jaws for packing so that the two first clamping jaws for packing are close to or away from each other.

[0101] Specifically, the first boxing gripper 521 includes a first boxing jaw and a first boxing clamping cylinder. The first boxing clamping cylinder is connected to the boxing fixture drive structure 523. The first boxing clamping cylinder drives the two first boxing jaws, causing them to move closer or further away from each other, thereby clamping or releasing the target product. The simple structure of the first boxing jaw and the first boxing clamping cylinder ensures stable clamping and effectively reduces operating costs.

[0102] In one embodiment of the present invention, the second holder 522 for packaging includes:

[0103] Two second clamping jaws for packing are arranged opposite to each other; and

[0104] The second clamping cylinder for box packing, the box driving assembly 510 drives and connects the second clamping cylinder for box packing, and the second clamping cylinder for box packing drives and connects the two second clamping jaws for box packing so that the two second clamping jaws for box packing move closer to or farther away from each other, and the box packing expansion assembly 530 is connected to the second clamping jaw for box packing to move synchronously with the second clamping jaw for box packing.

[0105] Specifically, the second packing clamp 522 includes a second packing jaw and a second packing clamping cylinder. Among them, the second packing clamping cylinder is connected to the packing drive assembly 510, and the second packing clamping cylinder drives the connection of the two second packing jaws so that the two second packing jaws move closer to or away from each other, thereby clamping or releasing the target product. The packing expansion assembly 530 is connected to the second packing jaw. When the two second packing jaws move away from each other to release the target product, the packing expansion assembly 530 moves synchronously with the second packing jaw, thereby abutting against the inner wall of the cavity. As the two second packing jaws continue to move away, the packing expansion assembly 530 expands and opens the cavity. It can be understood that in the process of releasing the target product by the second packing jaw, the expansion of the cavity can be achieved synchronously by the packing expansion assembly 530, and the structure is more simple and compact.

[0106] In one embodiment of the present invention, the carton expansion assembly 530 includes an expansion rod, one end of the expansion rod is connected to the carton second clamp, and the other end of the expansion rod extends in a direction away from the carton first clamp 521. Specifically, the carton expansion assembly 530 includes an expansion rod, one end of the expansion rod is connected to the carton second clamp, and the other end of the expansion rod extends in a direction close to the mold cavity. In this way, when the carton drive assembly 510 drives the carton first clamp 521 and the carton second clamp 522 to move above the mold cavity, one end of the expansion rod can extend into the interior of the mold cavity. When the carton second clamp releases the short side of the target product, the expansion rod follows the movement of the carton second clamp, abuts and expands the mold cavity.

[0107] In one embodiment of the present invention, each second boxing jaw is equipped with at least one expansion rod. It is understood that having one expansion rod in each of the two second boxing jaws can reduce structural complexity; having one expansion rod in each of the two second boxing jaws can simultaneously abut or expand opposite sides of the mold cavity, thereby improving the expansion effect of the mold cavity. In specific applications, the preferred method can be selected based on the actual application and is not limited here.

[0108] In one embodiment of the present invention, the two second cartoning jaws are provided with avoidance notches on their sides facing each other, and the expansion rod is located below the avoidance notches. This avoidance notch allows obstacles to be avoided, thereby improving the smoothness of the two second cartoning jaws in gripping the short sides of the target product.

[0109] In one embodiment of the present invention, two sets of box packing clamping assemblies 520 are provided at intervals, and the box packing driving assembly 510 drives and connects the two sets of box packing clamping assemblies 520. In this way, during the box packing process, the two sets of box packing clamping assemblies 520 can work simultaneously, effectively improving the box packing efficiency.

[0110] In one embodiment of the present invention, the packing clamping assembly 520 grips two target products at a time, placing the front faces of the two target products in contact with each other. This allows the packing clamping assembly 520 to place at least two target products into the same mold cavity at a time, further improving packing efficiency. Furthermore, the front faces of the two target products are in contact with each other, preventing them from being exposed and scratched by the mold cavity.

[0111] In one embodiment, the packing clamping assembly 520 clamps two target products at a time, and the front faces of the two target products are placed against each other. Figure 5 , the bag folding and packing device also includes:

[0112] The temporary storage mechanism 100 is movably disposed below the first turning mechanism 200 to place the first target product. Optionally, the temporary storage mechanism 100 includes a temporary storage plate having a temporary storage position on it, and the first target product is placed in the temporary storage position.

[0113] The first flipping mechanism 200 is disposed above the temporary storage mechanism 100 and is used to flip the second target product so that the front surfaces of the first target product and the second target product are placed side by side to form a target product group. Optionally, the first target product and the second target product can be similar products or different products. The first target product and the second target product both have a display surface (i.e., the front surface). Placing the front surfaces of the first target product and the second target product side by side or close together can protect the display surface during packaging and prevent the mold cavity from scratching the display surface;

[0114] The second flip mechanism 300 is provided on one side of the first flip mechanism 200 to grip and flip the target product group. In order to facilitate the second flip mechanism 300 to grip the target product group, the temporary storage position on the temporary storage plate is provided with an avoidance hole.

[0115] In the technical solution adopted in this embodiment, the first target product is placed face up on the temporary storage mechanism 100, and the second target product is placed face up on the first flipping mechanism 200. The first flipping mechanism 200 then drives the second target product placed thereon to flip 180 degrees, so that the front of the second target product faces downward. Subsequently, the temporary storage mechanism 100 moves to the bottom of the second target product, and the first flipping mechanism 200 places the second target product on top of the first target product. At this time, the fronts of the first and second target products are facing each other and the bag opening of the packaging bag is in a horizontal state, forming a target product group. Then, the second flipping mechanism 300 clamps the target product group on the temporary storage mechanism 100 and flips it 90 degrees, so that the bag opening of the packaging bag faces downward, making it easier for the bag folding clamping assembly 420 to clamp the target product group for bending.

[0116] In one embodiment of the present invention, referring to Figure 6 , the first turning mechanism 200 includes:

[0117] The first rotating rod 210 is rotatably disposed above the temporary storage mechanism 100;

[0119] The first clamp 220 , the first telescopic member and the first clamp 220 are drivingly connected to drive the first clamp 220 to move closer to or away from the first rotating rod 210 .

[0120] Specifically, the first flipping mechanism 200 includes a first rotating rod 210, a first telescopic member, and a first clamp 220. The first rotating rod 210 is rotatable, and the first telescopic member is arranged on the first rotating rod 210 and can rotate synchronously with the first rotating rod 210. The first telescopic member is driven and connected to the first clamp 220, and can drive the first clamp 220 to move vertically up and down, so that the first clamp 220 can clamp or release the second target product. At the same time, the first rotating rod 210 can drive the first clamp 220 to flip the clamped second target product. Optionally, the first rotating rod 210 is connected to a drive motor and can rotate under the drive of the drive motor. In one embodiment, the first telescopic member can be a telescopic cylinder.

Through one suction and rotation, a plurality of target product groups can be formed for the folding bag clamping assembly 420 to clamp, thereby effectively improving production efficiency. Optionally, a pulley is provided at the end of each rotating rod, and a driving motor drives a connecting belt, which is sleeved on the pulley, and then the belt can drive the plurality of first rotating rods 210 to rotate synchronously, and the structure is simpler. In one embodiment, the flipping angle of the first rotating rod 210 is 180 degrees, so that the second target product is flipped to face down.

[0123] A second rotating rod 310 is rotatably arranged; and

[0124] The second clamp 320 is disposed on the second rotating rod 310 and rotates synchronously with the second rotating rod 310 . A plurality of second clamps 320 are provided at intervals along the axial direction of the second rotating rod 310 .

Optionally, multiple second clamps 320 are provided, and the multiple second clamps 320 are spaced apart along the axial direction of the second rotating rod 310. This allows multiple target product groups to be clamped at once, thereby improving production efficiency. In one embodiment, the number of second clamps 320 is equal to the number of first clamps 220. In other embodiments, the second flipping mechanism 300 is mounted on a robotic arm or a two-axis movable module, which can drive the second flipping mechanism 300 to move, thereby clamping the target product group on the temporary storage mechanism 100 or placing the clamped target product group in a designated location. Optionally, the second rotating rod 310 can rotate at a 90-degree angle, so that the target product group can be flipped so that the bag opening faces downward.

Alternatively, the transport mechanism 700 can be a robotic arm or a three-axis mobile module, which is not limited herein.

[0128] In one embodiment of the present invention, two transport mechanisms 700 are provided. One of the two transport mechanisms 700 corresponds to the temporary storage mechanism 100, and the other of the two transport mechanisms 700 corresponds to the first turning mechanism 200.
