[0052] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0053] Combined with Figure 1 As shown, this embodiment provides a buckle box forming mechanism, which combines the ground cover forming function with the sky cover and ground cover assembly function. The buckle box forming mechanism of this embodiment specifically includes a body 9 and functional units such as a positioning unit 1, a gripping unit 2, a clamp unit 3, a mold unit 4 and a buckle unit 5 installed on the body 9. It should be noted that the "buckle box" of this embodiment refers to the effect or function of buckling the sky cover 7 on the ground cover, and the "buckle" of this embodiment refers to the action in the process of assembling the sky cover 7 and the ground cover.

[0054] The positioning unit 1 of this embodiment is used to receive the material sheet 6 transferred by machinery or manual labor, and adjust the material sheet 6 to the loading position. The material sheet 6 includes a main body and edges to be bent connected to the four sides of the main body. The "loading position" of this embodiment means that the material sheet 6 can be in a position that completely corresponds to the grasping unit 2, so that the grasping unit 2 can accurately grasp the material sheet 6, and in the subsequent forming process, the material sheet 6 is in the correct position to be formed.

[0055] The grabbing unit 2 of this embodiment is used to grab the material sheet 6 on the positioning unit 1 and transport the material sheet 6 to the clamping unit 3. During the process of grabbing and lowering the material sheet 6, the grabbing unit 2 moderately keeps the material sheet 6 parallel to the horizontal plane, and the material sheet 6 only moves horizontally without any deflection or flipping, so that the material sheet 6 can be located in the exact position for subsequent molding.

[0056] The clamp unit 3 of this embodiment can be moved from the forming position to the snap-fitting position on the machine body 9. The "forming position" mentioned in this embodiment refers to the position where the material plate 6 is formed into the floor cover, and the "snap-fitting position" mentioned in this embodiment refers to the position where the ceiling cover 7 and the floor cover complete the snap-fitting action.

[0057] The clamp unit 3 of this embodiment has a first platform 31 that supports the material plate 6 and can be raised and lowered. A guide structure 32 is arranged around the first platform 31 . The inner contour surrounded by the guide structure 32 has the same shape and size as the main body of the material plate 6 .

[0058] Correspondingly, the mold unit 4 of the present embodiment is located above the molding position, and the mold unit 4 has a liftable mold head 41 to press down the first carrier 31. The shape and size of the bottom surface of the mold head 41 are the same as the shape and size of the main body of the material sheet 6. Through the downward pressure of the mold head 41 and the guidance of the guide structure 32 and the ability of the first carrier 31 to descend under the action of the mold head 41, the material sheet 6 can be pressed down to pre-form into a floor cover. Preferably, the molding process of the present embodiment can be divided into two steps. The first step is pre-forming, that is, the mold head 41 presses down the carrier and the material sheet 6 on the carrier to the first position to achieve pre-forming, and then presses down to the second position to make the material sheet 6 completely formed.

[0059] The buckling unit 5 of this embodiment is used to transport the sky cover 7 to the buckling position, and buckle the sky cover 7 on the formed ground cover, thereby achieving the buckling of the sky cover 7 and the ground cover.

[0060] The buckle box forming mechanism of this embodiment realizes the automatic forming of the ground cover through the positioning unit 1, the grasping unit 2, the clamp unit 3 and the mold unit 4, and realizes the buckling of the roof cover 7 and the ground cover through the buckling unit 5. The whole process does not require human intervention, which improves production efficiency, reduces costs, and ensures the forming effect of the ground cover and the buckling effect of the roof cover 7 and the ground cover.

[0061] The structure of the above-mentioned functional units of the buckle box forming mechanism of this embodiment is described below.

[0062] Combined with Figure 2 and 3 As shown, the positioning unit 1 of this embodiment includes a second carrier 11, a driving structure 12 and a positioning member 13; the second carrier 11 of this embodiment has the same shape and size as the material plate 6, and the driving structure 12 of this embodiment is located below the second carrier 11 and connected to the positioning member 13.

[0063] The positioning members 13 of this embodiment are located around the second carrier 11 , and can move the material plate 6 located on the second carrier 11 under the drive of the driving structure 12 .

[0064] The driving structure 12 and the positioning member 13 of this embodiment have various structural forms. In this embodiment, the driving structure 12 preferably includes a driving device 121, a first moving device 122 and a second moving device 123; the driving device 121 of this embodiment is connected to the first moving device 122 and is used to drive the first moving device 122 to move along the width direction of the second carrier 11.

[0065] The first moving device 122 of this embodiment has a shape similar to The first moving device 122 has a plate body, and positioning parts 124 and transmission parts 125 are provided on both sides, that is, each side has a positioning part 124 and a transmission part 125. The second moving device 123 of this embodiment is connected to the transmission part 125 and can move along the length direction of the second carrier 11 under the drive of the transmission part 125.

[0066] The positioning member 13 of this embodiment includes a first positioning block 131 disposed on the positioning portion 124 and a second positioning block 132 disposed on the second moving device 123 .

[0067] Specifically, the transmission part 125 of this embodiment includes a guide surface arranged on the side of the first moving device 122, and the second moving device 123 is provided with a first roller 126 that rolls with the guide surface.

[0068] Through the above structure, only one driving device 121 is needed to realize the movement of the first moving device 122 and the second moving device 123, thereby completing the positioning of the first positioning block 131 and the second positioning block 132 on the material plate 6, with precise transmission and simple transmission structure.

[0069] Combined with Figure 1 As shown, the grabbing unit 2 of this embodiment includes a first mounting frame 21, a first walking structure 22 and a first suction cup grabbing structure; the first mounting frame 21 of this embodiment is located on the machine body 9; the first walking structure 22 of this embodiment can move on the first mounting frame 21, and the first walking structure 22 can be driven by a gear rack or by a walking wheel; the first suction cup grabbing structure is connected to the first walking structure 22 and is used to suck the material sheet 6 on the positioning unit 1. Preferably, in order to ensure the continuity and efficiency of the operation, two sets of first walking structures 22 and first suction cup grabbing structures can be installed on the first mounting frame 21 of the grabbing unit 2 of this embodiment, one set of the first walking structure 22 and the first suction cup grabbing structure moves the transferred material sheet 6 to a preset position, and the other set of the first walking structure 22 and the first suction cup grabbing structure moves the material sheet 6 from the preset position to the forming position, so that the continuity of feeding can be ensured and the operation efficiency can be improved.

[0070] Combined with Figure 4 and 5 As shown, the mold unit 4 of this embodiment may include a lifting structure 42 and a mold head 41. The lifting structure 42 may be a cylinder or an electric cylinder, etc. The lifting structure 42 is used to drive the mold head 41 to move up and down, and the position of the mold head 41 of this embodiment on the lifting structure 42 is adjustable. The specific adjustment method can be achieved through an adjusting device 43. The adjusting device 43 may include two adjusting plates, which are connected to each other and whose positions can be adjusted by structures such as bolts, one of which is connected to the lifting structure 42, and the other is connected to the mold head 41.

[0071] Combined with Figure 6-8 As shown, the first platform 31 of this embodiment is connected to a buffer cylinder 35 at the bottom, and the guide structure 32 of this embodiment includes a second roller 321, a baffle 322 and a baffle 323; the second roller 321 of this embodiment is arranged on one of the two opposite sides of the first platform 31, and the baffle 322 is arranged on the other of the two opposite sides of the first platform 31; the second roller 321 and the baffle 322 are used together to form the long side of the floor cover. Specifically, the second roller 321 is installed on the second mounting frame 33, and preferably, the second mounting frame 33 and the roller can move in a direction close to or away from the first platform 31.

[0072] In this embodiment, one of the two stoppers 323 is disposed at one of the two opposite ends of the first carrier 31 , and the other is disposed at the other of the two opposite ends of the first carrier 31 , for forming the short side of the floor cover.

[0073] The second roller 321 of the present embodiment includes a wheel body and a wheel axle. Preferably, in order to provide a certain buffer during the downward pressing process of the mold head 41, the wheel axle of the present embodiment is connected to the second mounting frame 33 through an elastic member 34, so that when the downward pressure is too large, the roller can have a certain amount of movement relative to the second mounting frame 33, and can be restored to the initial position through the elastic member 34, and the elastic member 34 can specifically be a spring.

[0074] Combined with Figure 9-13 As shown, the buckling unit 5 of this embodiment includes a flipping device 51 and a conveying and buckling device 52. The flipping device 51 is used to flip the top cover 7 to the loading position. This design is because the previous process of the buckle box forming mechanism is the forming of the top cover 7. The position of the formed top cover 7 after unloading is lower than the loading position of this mechanism. The conveying and buckling device 52 of this embodiment is used to convey the top cover 7 at the loading position to the buckling position, and buckle the top cover 7 on the formed floor cover.

[0075] Specifically, the flipping device 51 of the present embodiment includes a flipping driving component 511 and a second suction cup grasping structure 512. The flipping driving component 511 can be composed of a motor and a third mounting frame 513 and other structures. The second suction cup grasping structure 512 is installed on the third mounting frame 513. The second suction cup grasping structure 512 sucks the sky cover 7. The motor drives the third mounting frame 513 and the second suction cup grasping structure 512 thereon to rotate so that the sky cover 7 rotates to the loading position. It should be noted that the loading position of the sky cover 7 of the present embodiment is different from the above-mentioned loading position of the material plate 6, and the specific position is determined according to design requirements.

[0076] The conveying and fastening device 52 of this embodiment includes a fourth mounting frame 521 and a second walking structure 522. Preferably, in order to ensure the continuity and efficiency of the operation, the number of the second walking structures 522 of this embodiment can be two or more as shown in the figure. The two second walking structures 522 respectively drive the canopy 7 to walk in their respective areas. The second walking structure 522 has a lifting device 523 and a third suction cup grasping structure (or other mechanical grasping structure) to absorb the canopy 7. The second walking structure 522 has the same or similar structural form as the first walking structure 22. The difference is that in this embodiment, the second walking structure 522 near the fastening position is designed to be flippable to Fig.13 The turning over can drive the third suction cup grabbing structure to turn over through the rotating structure 524, so that the sky cover 7 is at a certain angle with the ground cover in the buckling position, which is convenient for the buckling of the two. That is, the lifting device 523 can be connected to the body of the walking structure and the rotating structure 524 respectively, and the rotating structure 524 is connected to the third suction cup grabbing structure. The rotating structure 524 can be any existing device that can rotate the components connected thereto, such as a motor, a cylinder, an electric wheel, etc.

[0077] Preferably, in order to further improve work efficiency, the present embodiment is provided with a turntable 8 on the machine body 9, and a plurality of clamp units 3 are installed on the turntable 8 at intervals along the circumference of the turntable 8. The rotation of the turntable 8 moves the clamp units 3 from the forming position to the snapping position, thereby ensuring the continuity of the operation and greatly improving the operation efficiency. In addition, a plurality of snapping units 5 can be arranged at intervals around the turntable 8 to perform the snapping operation of the sky cover 7 on a plurality of formed ground covers respectively.

[0078] The working process of the buckle box forming mechanism of this embodiment is described below:

[0079] First, the material sheet 6 is loaded manually or mechanically (preferably mechanically) and loaded onto the positioning unit 1. The multiple positioning members 13 of the positioning unit 1 adjust the horizontal position of the material sheet 6 and adjust the material sheet 6 to the preset loading position. Then the grabbing unit 2 is started. The two grabbing units 2 work together to share the stroke, which shortens the operation time of grabbing multiple material sheets 6. Subsequently, the material sheet 6 is grabbed onto the clamp unit 3. Under the action of the controller and other structures, the mold head 41 presses down the first carrier 31. The specific pressing action process can be designed according to needs.

[0080] After the mold head 41 presses down to form the ground cover, the turntable 8 rotates to rotate the formed ground cover to the buckling position, and the buckling unit 5 turns the roof cover 7 over and transports it to the buckling position, and then performs a certain deflection so that the roof cover 7 and the ground cover are at a certain inclination angle, and finally the roof cover 7 is lowered to complete the buckling of the roof cover 7 and the ground cover.

[0081] In the description of the present invention, it is necessary to understand that the terms "inside", "outside", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as a limitation on the present invention.

[0082] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.
