[0060] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0061] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0062] The invention provides a plate splicing system, which is used for splicing plates and is particularly suitable for manufacturing wall panels in a refrigerating box, that is, forming the wall panels by splicing plates.

[0063] See also Figure 1 The sheet material splicing system in the preferred embodiment of the present invention includes a loading mechanism 1, a conveying mechanism 2, a preforming mechanism 3, a displacement mechanism 4, a bite mechanism 5 and a unloading mechanism 6.

[0064] by Figure 1 With reference to the viewing direction, the sheet 91 is sequentially conveyed from upstream to downstream, that is, the loading mechanism 1, the conveying mechanism 2, the preforming mechanism 3, the shifting mechanism 4, the bite mechanism 5 and the unloading mechanism 6 of the sheet splicing system are sequentially arranged.

[0065] Combination Figure 1 and Figure 2 The sheet 91 enters the conveying mechanism 2 through the feeding mechanism 1, and the conveying mechanism 2 conveys the sheet 91 to the preforming mechanism 3. The preforming mechanism 3 processes the sheet 91 so that the opposite sides of the sheet 91 are respectively formed into an L-shaped interface and a V-shaped interface, that is, a sheet 92 with an interface. The displacement mechanism 4 then rotates the sheet 92 with the interface 90 degrees and transmits it to the bite mechanism 5. The bite mechanism 5 bites the two sheets 92 with the interface so that the L-shaped interface of one sheet 92 with the interface bites with the V-shaped interface of the other sheet 92 with the interface to obtain a spliced ​​sheet 93, and conveys it outward through the unloading mechanism 6.

[0066] The specific structure of the plate 92 with an interface is shown in Figure 3 The plate 92 with an interface includes a left fold 922 and a right fold 921 located on opposite sides of the plate body, wherein the left fold 922 includes a first fold that is integrally bent upward and extended from the plate body, and a second fold that is bent outward and obliquely downward from the top of the first fold. The first fold and the second fold are in an inverted V shape, so it is called a V-shaped interface. The right fold 921 is integrally extended upward from the plate body, and the right fold 921 is perpendicular to the plate body and is L-shaped, so it is called an L-shaped interface.

[0067] The following are detailed explanations one by one.

[0068] For the convenience of description, the conveying direction of the plate 91, that is, the direction from upstream to downstream, is defined as the longitudinal direction, and the direction perpendicular to the longitudinal direction in the horizontal direction is defined as the transverse direction.

[0069] The feeding mechanism 1 includes a fixed frame, a grabbing assembly, a lifting assembly and a moving assembly. The moving assembly is arranged on the fixed frame, connected to and drives the lifting assembly to move back and forth in the longitudinal direction. The lifting assembly is connected to and drives the grabbing assembly to lift. The grabbing assembly is used to grab the plate 91. The feeding mechanism 1 drives the grabbing assembly to move by lifting and moving the lifting assembly and the longitudinal moving assembly.

[0070] The moving assembly includes a longitudinal guide rail, a longitudinal sliding block and a longitudinal force member. The longitudinal guide rail is arranged on the fixed frame and extends in the longitudinal direction. The longitudinal sliding block can slidably cooperate with the longitudinal guide rail. The longitudinal force member drives the longitudinal sliding block to move on the longitudinal guide rail. In other embodiments, the moving assembly can also drive the lifting assembly to move back and forth in the lateral direction, which can be specifically set according to actual needs.

[0071] The lifting assembly includes a lifting slide, a lifting slider and a lifting power member. The lifting slide is arranged on both sides of the longitudinal sliding slider and is arranged along the height direction of the longitudinal sliding slider. The lifting slider is fixedly connected to the grabbing assembly and slidably cooperates with the lifting slide. The lifting power member is connected to and drives the lifting slider to move on the lifting slide, thereby driving the grabbing assembly to move along the lifting slide.

[0072] The grabbing assembly includes a plurality of pairs of grabbing arms, and each pair of grabbing arms can move toward each other to grab the plate 91 or move away from each other to put down the plate 91.

[0073] In this embodiment, the feeding mechanism 1 is a robot.

[0074] The conveying mechanism 2 is used to convey the plate 91 along the conveying direction, and is arranged downstream of the feeding mechanism 1. The conveying direction is parallel to the longitudinal direction. Specifically in this embodiment, when the plate 91 is on the conveying mechanism 2, the length direction of the plate 91 extends along the longitudinal direction, the length direction of the plate 91 is the first direction, and the width direction is the second direction. In other embodiments, the width direction of the plate 91 can also be the first direction.

[0075] Specifically in this embodiment, the conveying mechanism 2 is a conveying roller. The conveying roller includes a roller body and a driving member for driving the roller body to rotate. The roller body rotates to move the sheet 91 in contact with the roller body forward, that is, the rotation direction of the roller body is the same as the conveying direction of the sheet 91, so that the roller body can convey the sheet 91 to the preforming mechanism 3. When describing the orientation, the present invention takes the direction from upstream to downstream of the sheet splicing system as the front, and the direction from downstream to upstream as the rear. Unless otherwise specified below, the definitions of front and rear are consistent with those herein.

[0076] Furthermore, the roller bodies are arranged at intervals in the longitudinal direction, that is, there is a gap between two adjacent roller bodies. Each roller body includes a rotating shaft and a plurality of rotating wheels arranged at intervals on the rotating shaft, the rotating shaft is fixedly connected to the rotating wheels, and the rotating shaft rotates to drive the rotating wheels to rotate, thereby making the plate 91 move along each roller body.

[0077] The conveying roller extends to the preforming mechanism 3, that is, the conveying roller can convey the sheet 91 to the preforming mechanism 3, and the degree of automation is high. In other embodiments, the conveying mechanism 2 can also be a conveying belt, a conveying chain, etc., which can be selected according to actual conditions.

[0078] The preforming mechanism 3 is used to form the plate 91 into a plate 92 with an interface, that is, the two opposite sides have an L-shaped interface and a V-shaped interface. In this embodiment, along the two sides of the width direction of the plate 91, one side forms an L-shaped interface, and the other side forms a V-shaped interface.

[0079] The preforming mechanism 3 includes a base, a left forming device and a right forming device which are distributed parallel to each other and arranged on both sides of the width direction of the base, as well as a guiding device and a conveying device.

[0080] The length direction of the base is parallel to the conveying direction, that is, the length direction of the base extends longitudinally. The upper surface of the base is flush with or lower than the upper surface of the conveying mechanism 2, so that the plate 91 can smoothly enter the preforming mechanism 3 from the conveying mechanism 2.

[0081] The two conveying devices are arranged on both sides of the width direction of the base, and are used to convey the plate 91 so that the plate 91 is formed during the movement. The conveying device on each side includes a plurality of conveying roller sets arranged at intervals along the length direction of the base. Each conveying roller set includes an upper conveying roller 311 and a lower conveying roller 312 arranged in pairs, and the axes of the upper conveying roller 311 and the lower conveying roller 312 extend in the transverse direction, and there is a gap between the upper conveying roller 311 and the lower conveying roller 312.

[0082] The two guide devices are arranged on both sides of the width direction of the base and are arranged at the front end of the base to guide the plate 91 entering the preforming mechanism 3. In this embodiment, the two guide devices are respectively located on the outside of the two conveying devices. Each guide device includes an upper guide roller 321 and a lower guide roller 322 arranged in pairs along the upper and lower directions. There is a guide space between the upper guide roller 321 and the lower guide roller 322. The guide spaces of the two guide devices are located at the same horizontal height and jointly guide and convey a plate 91.

[0083] The lower guide rollers 322 each include an inner guide column and an outer guide column connected to the outer end of the inner guide column, and the inner guide column and the outer guide column are coaxial. The diameter of the outer guide column is larger than the diameter of the inner guide column, so that the outer circumference of the outer guide column exceeds the outer circumference of the inner guide column. That is, the inner guide column is used to support the plate 91, and the outer guide column is used to limit the plate 91 from moving outward, and the two guide rollers work together to play a guiding role.

[0084] The left forming device is used to form a V-shaped interface, and the right forming device is used to form an L-shaped interface. The left and right refer to the opposite sides along the width direction of the base. The left forming device and the right forming device are respectively located outside the two conveying devices.

[0085] See also Figure 4 The right forming device includes a plurality of right forming roller groups spaced apart along the length direction of the base. Each right forming roller group has a right clamping surface for clamping the plate 91, and along the conveying direction, the angle of the right clamping surface of the right forming roller group gradually decreases to 90 degrees to form an L-shaped interface.

[0086] Specifically, the right forming roller group includes a right upper forming roller 341 and a right lower forming roller 342 arranged in pairs, wherein there is a gap between the right upper forming roller 341 and the right lower forming roller 342. The outer periphery of the right upper forming roller 341 has an inclined surface from inside to outside and upward, and the outer periphery of the right forming roller has an inclined surface from inside to outside and upward. The two inclined surfaces together form a right clamping surface. In which, with the use state of the preforming mechanism 3 as a reference, the area enclosed by the left forming device and the right forming device is the inside, and the opposite is the outside.

[0087] Specifically in this embodiment, before the right clamping surface is 90 degrees, the upper right forming roller 341 includes an upper cylinder and an upper cone connected to the outer end of the upper cylinder, the diameter of the upper cone connecting the upper cylinder is the same as that of the upper cylinder, and the diameter of the upper cone gradually decreases from the inside to the outside. The lower right forming roller 342 includes a lower cylinder and a lower cone connected to the outer end of the lower cylinder, the diameter of the lower cone connecting the lower cylinder is the same as that of the lower cylinder, and the diameter of the lower cone gradually increases from the inside to the outside. When the right clamping surface is 90 degrees, the upper right forming roller 341 includes an upper cylinder. The lower right forming roller 342 includes an inner cylinder and an outer cylinder, and the diameter of the outer cylinder is greater than the diameter of the inner cylinder. The inner side surface of the outer cylinder is close to the outer end surface of the upper cylinder, and there is a gap between the two to accommodate the folded edge.

[0088] Along the conveying direction, that is, from front to back, the angle of the right clamping surfaces of the plurality of right forming roller groups gradually decreases to 90 degrees, thus completing the forming of the L-shaped interface.

[0089] After the sheet 91 moves to the right forming roller group, the sheet 91 begins to form a right fold 921 through the action of the right clamping surface. Specifically, from front to back, the angle between the sheet body and the right fold 921 gradually decreases to 90 degrees, so that the right fold 921 is perpendicular to the sheet body to form an L-shaped interface.

[0090] The left forming device includes a plurality of left forming roller groups arranged at intervals along the length direction of the base. Each left forming roller group has a left clamping surface for clamping the plate 91, and the left clamping surface includes a first left clamping surface and a second left clamping surface; along the conveying direction, the angle of the first left clamping surface gradually decreases to 90 degrees and then remains unchanged, and after the angle of the first clamping surface is 90 degrees, the angle of the second left clamping surface gradually decreases from 180 degrees to an acute angle, thereby forming a V-shaped interface.

[0091] See also Figure 5 In this embodiment, the V-shaped interface is formed by first forming an L-shape and then continuing to bend to form a V-shaped interface.

[0092] Specifically, the left forming roller group includes an upper left forming roller 331 and a lower left forming roller 332 which are arranged in pair, wherein a gap is provided between the upper left forming roller 331 and the lower left forming roller 332 .

[0093] Specifically in this embodiment, the first clamping surface of the left clamping surface can refer to the molding of the right clamping surface, so it is not repeated here. When the first clamping surface is 90 degrees, the angle of the second clamping surface is 180 degrees. Then from the front to the back direction, the angle of the second clamping surface gradually decreases to an acute angle.

[0094] When the second clamping surface is less than 180 degrees, the upper left forming roller 331 includes an upper left cylinder and an upper left cone connected to the outer end of the upper left cylinder, the upper left cylinder and the upper left cone are coaxial, and the inner end diameter of the upper left cone is smaller than the diameter of the upper left cylinder, and the diameter of the upper left cone gradually decreases from the inside to the outside. The lower left forming roller 332 includes a lower left cylinder and a lower left cone connected to the outer end of the lower left cylinder, the lower left cylinder and the lower left cone are coaxial, and the inner end diameter of the lower left cone is larger than the diameter of the lower left cylinder, and the diameter of the lower left cone gradually decreases from the inside to the outside.

[0095] When the second clamping surface is equal to 90 degrees, the upper left forming roller 331 includes a first cylinder and a second cylinder connected to the outer end of the first cylinder, the first cylinder and the second cylinder are coaxial, and the diameter of the second cylinder is smaller than the diameter of the first cylinder. The lower left forming roller 332 includes a third cylinder and a fourth truncated cone connected to the outer end of the third cylinder, the third cylinder and the fourth cylinder are coaxial, and the diameter of the fourth cylinder is larger than the diameter of the second cylinder.

[0096] When the second clamping surface is less than 90 degrees, the upper left forming roller 331 includes an upper left cylinder and an upper left cone connected to the outer end of the upper left cylinder, the upper left cylinder and the upper left cone are coaxial, and the inner end diameter of the upper left cone is smaller than the diameter of the upper left cylinder, and the diameter of the upper left cone gradually increases from the inside to the outside. The lower left forming roller 332 includes a lower left cylinder and a lower left cone connected to the outer end of the lower left cylinder, the lower left cylinder and the lower left cone are coaxial, and the inner end diameter of the lower left cone is larger than the diameter of the lower left cylinder, and the diameter of the lower left cone gradually increases from the inside to the outside.

[0097] After the sheet 91 moves to the left forming roller group, the sheet 91 is formed into a left fold 922 by the action of the left clamping surface. The left fold 922 includes a first fold and a second fold, the first fold is connected to the sheet body and is perpendicular to the sheet body. The second fold is connected to the top of the first fold and is bent downward on the outside of the first fold to form a V-shaped interface.

[0098] In this embodiment, the left forming device includes six groups of left forming rollers, and the right forming device also includes six groups of right forming rollers. The right forming device may include multiple groups of right forming rollers with right clamping surfaces of 90 degrees.

[0099] The shifting mechanism 4 is used to rotate the plate 92 with the interface so that the plate 92 with the interface is rotated to extend longitudinally in the width direction. Specifically, the upper surface of the shifting mechanism 4 is lower than or flush with the upper surface of the preforming mechanism 3, and can smoothly receive the plate 92 with the interface.

[0100] See also Figure 6 and Figure 7 The displacement mechanism 4 includes a base frame, two side transmission members 41, a support plate 42, a rotating member and a lifting member.

[0101] The side conveying members 41 are arranged on the bottom frame in parallel and at intervals in the horizontal direction. Each side conveying member extends in the longitudinal direction and conveys the plate in the longitudinal direction. In this embodiment, the side conveying member 41 is a conveyor belt.

[0102] The lifting member is arranged on the base frame and is located between the two side conveying members 41. Specifically, the lifting member has a fixed end and a free end, the fixed end is fixed on the base frame, and the free end can be lifted vertically relative to the fixed end. In this embodiment, the lifting member is an oil cylinder.

[0103] The rotating member is arranged on the free end of the lifting member and can be lifted and lowered. Specifically, the rotating member includes a fixed support ring, a rotating support ring and a rotating drive mechanism. The fixed support ring is fixedly connected to the free end, the rotating support ring is rotatably connected to the fixed support ring, and the rotating drive mechanism drives the rotating support ring to rotate relative to the fixed support ring. In this embodiment, the rotating support ring can rotate 90 degrees relative to the fixed support ring.

[0104] The support plate 42 is fixedly connected to the rotating support ring and can rotate with the rotating support ring. The support plate 42 is located in the middle of the longitudinal direction of the side conveyor 41, so that it can rotate when the middle of the plate 92 with the interface is located on the support plate 42.

[0105] The displacement process of the displacement mechanism 4 is as follows:

[0106] In the initial state, the support plate 42 is located between the conveying members 41 on both sides, and the upper surface of the support plate 42 is lower than the upper surface of the side conveyor belt or flush with the plate 92 with the interface. The plate 92 with the interface enters the displacement mechanism 4 and is conveyed by the side conveying member 41, so that the middle of the plate 92 with the interface is located on the support plate 42. The support plate 42 is raised by the lifting member, so that the support plate 42 is raised upward beyond the side conveying member 41, so that the plate 92 with the interface is separated from the side conveying member 41 and supported by the support plate 42. Then, the plate 92 with the interface is rotated by the rotating action of the rotating member, so that the plate 92 with the interface is rotated 90 degrees, and the rotation of the plate 92 with the interface is completed. Then, the support plate 42 is lowered by the lowering of the lifting member, so that the plate 92 with the interface after rotating 90 degrees falls on the conveying members 41 on both sides, and is continuously conveyed to the downstream bite mechanism 5 by the side conveying member 41.

[0107] Furthermore, along the longitudinal direction, intermediate conveying members 43 are respectively provided at both ends of the support plate 42. The conveying direction of each intermediate conveying member 43 is along the longitudinal direction, and the intermediate conveying member 43 is located between the conveying members 41 on both sides.

[0108] The snap-fit ​​mechanism 5 is used to snap-fit ​​two plates 92 with interfaces to achieve splicing.

[0109] Specifically, the snap-joining mechanism 5 includes a front conveying table 51, a rear conveying table 52, a splicing table 53 and a snap-joining device.

[0110] The front conveying platform 51 is arranged downstream of the shifting mechanism 4, and is used to support and convey the plate 92 with the interface. The conveying direction of the front conveying platform 51 is still along the longitudinal direction, from front to back, but the direction of the plate 92 with the interface on the front conveying platform 51 is shifted by the shifting mechanism 4, and the width direction of the plate 92 with the interface, i.e., the second direction, extends along the longitudinal direction. In this embodiment, the front conveying platform 51 is a conveyor chain or a conveyor belt.

[0111] The rear conveying platform 52 is disposed downstream of the front conveying platform 51, and is used to receive and support the plate 92 with an interface conveyed by the front conveying platform 51. The conveying direction of the rear conveying platform 52 is still along the longitudinal direction, from front to back, but the direction of the plate 92 with an interface on the rear conveying platform 52 is shifted by the shifting mechanism 4, and the width direction of the plate 91, i.e., the second direction, extends along the longitudinal direction. In this embodiment, the rear conveying platform 52 is a conveying chain or a conveyor belt.

[0112] The splicing table 53 is located between the front conveying table 51 and the rear conveying table 52, and they jointly support two plates 92 with interfaces, so that the L-shaped interface of one plate 92 with an interface is spliced ​​with the V-shaped interface of the other plate 92 with an interface. That is, the splicing table 53 and the front conveying table 51 jointly support a plate 92 with an interface, and the splicing table 53 and the rear conveying table 52 jointly support a plate 92 with an interface, and the two plates 92 with interfaces are spliced ​​on the splicing table 53.

[0113] Specifically, in this embodiment, the length direction of the splicing table 53 is parallel to the conveying direction of the front conveying table 51 , that is, the length direction of the splicing table 53 extends in the longitudinal direction.

[0114] Specifically, the rear conveying table 52 can be raised and lowered relative to the splicing table 53 to facilitate the splicing of the L-shaped interface of one plate 92 with an interface with the V-shaped interface of another plate 92 with an interface.

[0115] See also Figure 8 and Fig. 9 , the cooperation process between the front conveying platform 51 and the rear conveying platform 52 is as follows:

[0116] After the front conveyor 51 conveys the plate 92 with the interface to the rear conveyor 52, the L-shaped interface of the plate 92 with the interface is located on the rear conveyor 52, and the V-shaped interface is located on the splicing table 53. Then the rear conveyor 52 is raised and exceeds the splicing table 53. Then another plate 92 with the interface is conveyed to the front conveyor 51, so that the L-shaped interface of the plate 92 with the interface contacts the V-shaped interface of the previous plate 92 with the interface. The rear conveyor 52 is lowered to be flush with the splicing table 53, so that the two plates 91 are flush, and the L-shaped interface of one plate 91 is located inside the V-shaped interface of the other plate 91.

[0117] The bite-joining device is arranged corresponding to the splicing table 53 , and gradually forms and bites the interfaces of the two plates 91 on the splicing table 53 to obtain the spliced ​​plates 93 .

[0118] Specifically, the snap-joining device includes a gantry, and a nip roller group, a snap-joining assembly and a plurality of pressing rods 56 arranged on the gantry.

[0119] The plurality of pressing rods 56 are divided into two groups, and the two groups of pressing rods 56 are both located on the splicing platform 53 and arranged on both sides of the splicing platform 53, and respectively press the two plates 92 with interfaces located on the splicing platform 53. Specifically, the two groups of pressing rods 56 are arranged in parallel and spaced apart along the width direction of the splicing platform 53, i.e., the transverse direction. Each group of pressing rods 56 includes a plurality of pressing rods 56 arranged in parallel and spaced apart along the longitudinal direction.

[0120] The clamping rod 56 can be raised and lowered relative to the gantry, thereby allowing the plate 92 with the interface to be transported when it is raised upward, and clamping the plate 92 with the interface onto the splicing table 53 when it is lowered downward.

[0121] The bite assembly is arranged on the gantry and can move along the width direction of the splicing table 53, that is, transversely, so as to move along the first direction of the plate 92 with the interface at the interface of the two plates 92 with the interface to complete the bite of the two plates 92 with the interface.

[0122] Specifically, the bite assembly includes a plurality of bite roller groups 564 arranged at intervals along the width direction of the splicing table 53, that is, along the lateral direction. Each bite roller group 564 has a bite surface, and along the moving direction of the bite assembly, the angle of the bite surface gradually decreases.

[0123] Specifically, each bite roller group 564 includes a front bite roller and a rear bite roller arranged in pairs, and a bite surface is formed between the front bite roller and the rear bite roller. The rotation axes of the front bite roller and the rear bite roller both extend vertically. Among them, the front bite roller corresponds to the plate 92 with an interface supported by the front conveying platform 51; the rear bite roller corresponds to the plate 92 with an interface supported by the rear conveying platform 52. In this embodiment, the front bite roller acts on the L-shaped interface, and the rear bite roller acts on the V-shaped interface.

[0124] Specifically in this embodiment, the snap-in assembly includes five groups of snap-in rollers 564, see Fig.10 and Fig.11 , which includes a guide roller group 561, a first buckling roller group 562, a second buckling roller group 563, a bite roller group 564 and a shaping roller group 565 in sequence. Fig.10 Taking the viewing direction of as a reference, the guide roller group 561, the first snap-fit ​​roller group 562, the second snap-fit ​​roller group 563, the bite roller group 564 and the shaping roller group 565 are arranged in sequence from right to left in the view.

[0125] See also Fig.12 The front bite roller in the guide roller group 561 is in the shape of a truncated cone, the outer circumference of which matches the outer circumference of the V-shaped interface of the plate 91, and the rear bite roller of the guide roller group 561 is in the shape of a cylinder, thus playing a guiding role.

[0126] The rear interlocking roller in the first interlocking roller group 562 is cylindrical, and the front interlocking roller is also truncated cone-shaped. The diameter of the cone gradually decreases from top to bottom, and the angle between the outer peripheral surface of the cone and the vertical plane is smaller than the angle between the outer peripheral surface of the cone and the vertical plane in the front interlocking roller in the guide roller group 561, thereby reducing the angle of the V-shaped interface.

[0127] The front bite roller and the rear bite roller in the second engagement roller set 563 are both cylindrical and engage the two plates 92 with the interface.

[0128] The front bite roller and the rear bite roller in the bite roller group 564 are both cylindrical, wherein the outer circumference of the front bite roller is provided with an inwardly recessed groove, and the outer circumference of the rear bite roller is provided with an outwardly protruding convex ring, which can be snapped into the groove to bite the two plates 92 with interfaces together.

[0129] The shaping roller set 565 has the same structure as the bite roller set 564, which will not be described in detail. The shaping roller set 565 is used to adjust the bite of the two plates 92 with interfaces.

[0130] The nip roller group and the bite roller group 564 are placed on the gantry and are arranged with a horizontal spacing with the bite assembly, and can also move horizontally. In this embodiment, the nip roller group and the bite assembly are connected to a transition plate together, and move with the transition plate.

[0131] Specifically, the nip roller group includes two end nip rollers 551 and a middle nip roller 552. The rotating shafts of the end nip rollers 551 and the middle nip roller 552 extend in the longitudinal direction. In addition, along the width direction of the splicing table 53, that is, along the transverse direction, the two end nip rollers 551 are arranged at both ends of the bite assembly, and the middle nip roller 552 is located between the multiple bite roller groups 564, so as to press the plate 92 with the interface onto the splicing table 53.

[0132] In this embodiment, there is one middle pressing roller 552. One end pressing roller 551 is located above the guide roller group 561, the other end pressing roller 551 is located below the shaping roller group 565, and the middle pressing roller 552 is located between the second locking roller group 563 and the bite roller group 564.

[0133] The snap-in process of the snap-in device is as follows:

[0134] After the two plates 92 with interfaces are in place on the splicing table 53, the pressing rods 56 are lowered, and the two groups of pressing rods 56 respectively press the two plates 92 with interfaces on the splicing table 53. The bite assembly and the pressing roller are moved to one end in the transverse direction, and then the bite assembly and the pressing roller are lowered together to the plate 92 with interfaces, so that the pressing roller presses the plate 92 with interfaces, and the bite assembly and the pressing roller are moved together, so that the two move together. With the action of the multiple groups of bite rollers of the bite assembly, the bite between the L-shaped interface and the V-shaped interface is completed.

[0135] The unloading mechanism 6 is arranged downstream of the bite mechanism 5, and is used to transport the spliced ​​plates 93 outward. The unloading mechanism 6 can be a conveying roller, a conveying belt, a conveying chain, etc., which can be selected according to actual conditions. The structure of the unloading mechanism 6 can refer to the conveying mechanism 2, and will not be described in detail here.

[0136] The sheet splicing system in this embodiment is arranged in sequence from upstream to downstream, including a feeding mechanism 1, a conveying mechanism 2, a preforming mechanism 3, a displacement mechanism 4, a bite mechanism 5 and a discharge mechanism 6. The sheet 91 is fed by the feeding mechanism 1, the sheet 91 is transported by the conveying mechanism 2, and the sheet 91 is formed by the preforming mechanism 3. After the displacement of the displacement mechanism 4, the sheet 91 enters the bite mechanism 5 to realize the bite of the two sheets 91, and finally the spliced ​​sheet 93 is transported outward by the discharge mechanism 6. Therefore, the sheet splicing system has a high degree of mechanization throughout the process, so the splicing efficiency is high, and no manual intervention is required, which ensures the quality and stability of the splicing of the sheet 91, and thus makes the splicing consistency better. In addition, in this embodiment, the preforming mechanism 3 adopts a multi-pass spinning method to form an L-shaped interface and a V-shaped interface, which ensures the accuracy of the interface forming. The bite mechanism 5 adopts a movable bite assembly, so that the interface of the two sheets 92 with interfaces is gradually formed, which ensures the accuracy of the bite interface and the dimensional accuracy of the sheets 92 with interfaces after splicing.

[0137] In order to further enable those skilled in the art to understand in detail how the plate splicing system provided in this embodiment realizes the splicing of the plate 91, the specific process of the plate 91 splicing method will be described below.

[0138] The method for splicing the plate 91 comprises the following steps:

[0139] S1. The plate 91 is loaded onto the conveying mechanism 2 through the loading mechanism 1, and the conveying mechanism 2 conveys the plate 91 along a conveying direction.

[0140] Specifically, after the loading mechanism 1 grabs the plate 91, the plate 91 is placed on the conveying mechanism 2. In this embodiment, the plate 91 is placed in a manner such that the length direction of the plate 91 extends along the conveying direction.

[0141] The feeding speed of the feeding mechanism 1 , that is, the time interval between feeding two plates 91 , is actually set by comprehensively considering the speeds of the conveying mechanism 2 , the preforming mechanism 3 and the snapping mechanism 5 .

[0142] S2. The preforming mechanism 3 receives the plate 91 conveyed by the conveying mechanism 2 and preforms the plate 91 so that two opposite sides of the plate 91 are respectively formed into an L-shaped interface and a V-shaped interface.

[0143] Specifically, the preforming mechanism 3 forms a V-shaped interface and an L-shaped interface on both sides of the plate 91 through multiple roll forming of the left forming device and the right forming device, respectively, that is, a plate 92 with an interface is formed.

[0144] S3, the shifting mechanism 4 receives the plate formed by the preforming mechanism 3 and rotates it 90 degrees.

[0145] Specifically, in this embodiment, the two interfaces of the plate 92 with interfaces received by the shifting mechanism 4 are located on both sides of the transverse direction, and each interface extends in the longitudinal direction. After the shifting mechanism 4 shifts, the plate 92 with interfaces rotates 90 degrees, so that each interface of the plate 92 with interfaces extends in the transverse direction.

[0146] S4, the bite mechanism 5 receives the plate 91 rotated by the displacement mechanism 4, and splices and bites the L-shaped interface of one plate 92 with an interface with the V-shaped interface of another plate 92 with an interface.

[0147] Specifically, the two plates 92 with interfaces are moved to a preset position through the cooperation of the rear conveying table 52 and the front conveying table 51, that is, the L-shaped interface of one plate 92 with an interface contacts the V-shaped interface of the other plate 92 with an interface, and then the interface located on the splicing table 53 is bitten through the biting equipment.

[0148] S5, the spliced ​​plates 93 are transported outwards through the unloading mechanism 6.

[0149] The plate splicing method in this embodiment is to load the plate 91 through the feeding mechanism 1, convey the plate 91 through the conveying mechanism 2, and form the plate 91 through the preforming mechanism 3. After the displacement of the displacement mechanism 4, the plate 91 enters the bite mechanism 5, and the bite of the two plates is realized through the bite of the bite mechanism 5. Finally, the spliced ​​plate 93 is conveyed outward through the unloading mechanism 6. The plate splicing method has a high degree of mechanization throughout the process and high splicing efficiency. In addition, the method adopts a multi-pass spin forming method to form the L-shaped interface and the V-shaped interface, which ensures the accuracy of the interface forming. A movable bite assembly is used to gradually form the interface of the two plates 91, which ensures the accuracy of the bite interface and the dimensional accuracy of the plates after splicing.
