[0026] Compared with the prior art, the above-mentioned fully automatic composite laminating machine has the following beneficial effects:

[0027] The first workpiece is conveyed by the loading mechanism, the gluing mechanism glues the conveyed first workpiece, and then the feeding mechanism provides the second workpiece to the transfer mechanism, and the transfer mechanism bonds the second workpiece to the glued first workpiece, thereby realizing the automatic bonding operation of the two packages of the first workpiece and the second workpiece, saving manpower and improving bonding efficiency.

[0028] The carrying platform is driven to move by the feeding drive to convey the first workpiece, i.e., the package. The carrying platform can install and fix the mold, and then the package can be placed in the mold. The package is supported horizontally and stably on the carrying platform through the mold, ensuring that the loading mechanism can convey non-planar packages horizontally and stably, eliminating the limitations of traditional belt structures on package transportation and improving the adaptability of the loading mechanism.

[0029] By arranging pressure relief surfaces on both sides of the load-sharing portion, and slanting the pressure relief surfaces on both sides so as to gradually approach each other from the stabilizing portion toward the guiding portion, the hook block is pressed against the pressure relief surface of the load-sharing portion, so that the impact load borne by the bearing platform can be converted into a part of the horizontal component through the inclined setting of the pressure relief surface, thereby reducing the positive pressure between the bearing slider and the bearing slide rail, improving the bearing limit of the bearing platform, and ensuring the reliability of the bearing platform in the subsequent process of bonding the packaging.

[0030] By arranging the top of the glue coating roller and the glue leveling roller close to the glue injection assembly flush, the glue capacity of the glue drop zone is increased without changing the structure of the glue coating roller, so as to ensure that the glue leveling roller can apply more complete glue on the glue coating roller during the rotation of the glue coating roller and the glue leveling roller, thereby making the glue applied by the glue coating roller to the package more uniform, thereby improving the bonding effect of the package. In addition, by arranging the top of the glue coating roller and the glue leveling roller flush, the height position of the glue drop zone can be increased, and then the glue leveling roller can better apply the glue evenly on the glue coating roller by utilizing the downward flow characteristic of the glue, thereby further ensuring the bonding effect of the package.

[0031] When the glue coating mechanism is started, the glue liquid is in the state of being bonded between the glue coating roller and the glue leveling roller. Therefore, a large impact load will be generated between the glue coating roller and the glue leveling roller when the glue coating roller starts to rotate. By rotatably connecting the glue leveling roller and the glue leveling slide, sliding the glue leveling slide on the mounting frame, and elastically pressing the glue leveling slide through elastic parts and a pressure block, the impact load at startup can be unloaded by moving the glue leveling slide to compress the elastic parts, thereby avoiding damage to the rotating connection position of the glue leveling roller and improving the reliability of the glue coating mechanism.

[0032] By arranging the end plate to support the roller plate, a cavity is formed between the roller plate and the central axis, thereby reducing the heat transfer efficiency from the roller plate to the central axis. In the process of coating the packaging with glue, the thermal insulation performance of the contact point between the outer side of the roller plate and the glue is improved, preventing the glue from solidifying and adhering to the outer side of the rubber roller, avoiding the waste of glue, and eliminating the need for regular cleaning and maintenance of the rubber roller, thereby reducing production costs.

[0033] By providing support by ribs between the central axis and the roller plate, the bearing capacity of the roller plate is improved, and deformation of the roller plate due to the cavity is avoided, which makes it impossible to evenly apply glue to the packages. By providing a rib structure, the feasibility of the cavity structure is ensured, while the deformation resistance of the roller plate is improved, thereby ensuring the stability of the roller plate in applying glue to the packages.

[0034] By arranging a first adjustment hole and a second adjustment hole on the feeding table, and the first adjustment hole and the second adjustment hole are alternately arranged in the first direction and spaced apart in the second direction, and by arranging an assembly hole on the film guide frame, at least part of the first adjustment hole and the second adjustment hole are overlapped with the assembly hole, so that the installation position and installation direction of the film guide frame on the feeding table are adjustable, and the film guide frame can be used to enclose packages of different specifications and shapes, thereby ensuring that the packages are stacked on the feeding table, without setting film guide frames of various specifications, thereby improving the adaptability of the film guide frame to stacking packages of different specifications and shapes, and reducing production costs.

[0035] By arranging the first feeding part and the second feeding part on the feeding table, and switching the first feeding part or the second feeding part to correspond to the feeding position through the material placement driving part, it is achieved that when one of the first feeding part and the second feeding part is feeding, the other can be used to load packages, so as to ensure that the machine does not need to be stopped for loading when loading packages, thereby improving production efficiency.

[0036] By arranging the first adjustment hole and the second adjustment hole in a staggered manner in the second direction, the length dimension L of the first adjustment hole and the second adjustment hole is greater than or equal to the spacing H, the length dimension of the two assembly holes on the film guide frame is equal to L, and the spacing between the two assembly holes is equal to H, so that the arrangement position and rotation angle of the film guide frame on the feed table are adjustable, ensuring that the film guide frame can fix packages of different specifications and shapes, greatly improving the adaptability of the film guide frame.

[0037] By installing the transfer slide and the transfer drive component on the crossbeam, and arranging the top support part and the bottom support part on the crossbeam to reinforce the installation part, the bearing capacity of the crossbeam is improved, and the deformation of the crossbeam due to long-term impact load and torque is avoided, thereby ensuring the alignment accuracy between the packages and improving the bonding effect.

[0038] By providing a positioning groove on the positioning plate and an embedded part on the crossbeam, the crossbeam is positioned relative to the installation position of the transfer bracket by embedding the embedded part into the positioning groove, and no additional leveling and calibration operations are required, thereby improving assembly accuracy and assembly efficiency. In addition, the embedded fixing structure can also improve the reliability of assembly between the positioning plate and the crossbeam. The positioning plate can also absorb part of the load borne by the crossbeam, thereby reducing the load impact borne by the transfer bracket, preventing the transfer bracket from deforming and affecting the alignment accuracy between the packages, and further improving the bonding effect between the packages.

[0039] By configuring the mounting disk to have an outer ring portion surrounding the outside of the inner ring portion, and then connecting the inner ring portion and the outer ring portion by a connecting portion, the first adjusting block adjusts the setting position of the first air nozzle along the circumferential direction of the outer ring portion, and the second adjusting block adjusts the setting position of the second air nozzle along the radial direction of the connecting portion. The first air nozzle and the second air nozzle cooperate to adsorb and grasp the package, thereby achieving all-round adjustment in the circumferential and radial directions to meet the grasping requirements of packages of different structures and sizes, improve adaptability of use, and there is no need to replace the mounting disk when grasping packages of different specifications, thereby reducing processing costs and improving processing efficiency.

The feeding driving wheel 133 drives the feeding belt 135 to rotate together, and the feeding belt 135 drives the carrying platform 12 to move linearly. The advantage of using the feeding belt 135 to drive the carrying platform 12 to move is that the feeding belt 135 is a flexible component. During the linear movement of the carrying platform 12, the inertia will generate an impact load on the feeding drive 13. The impact load generated by the carrying platform 12 can be effectively absorbed by the flexible deformation of the feeding belt 135, thereby eliminating the impact of the impact load on the feeding drive 13, and improving the reliability and service life of the feeding drive 13.

[0076] Furthermore, the bearing rail 15 is in the shape of an elongated strip, and the bearing rail 15 is extended along the moving direction of the bearing platform 12; the bearing slider 14 is slidably arranged on the bearing rail 15, and the bearing slider 14 and the bearing rail 15 are arranged between the bearing platform 12 and the base frame 11 to guide the movement of the bearing platform 12 and ensure the stability of the movement of the bearing platform 12. It can be understood that one of the bearing rail 15 and the bearing slider 14 is connected to the base frame 11, and the other is connected to the bearing platform 12. The specific connection between the two is not limited here, and it is sufficient to ensure that the relative movement between the bearing platform 12 and the base frame 11 can be guided. In this embodiment, the bearing rail 15 is connected to the base frame 11, and the bearing slider 14 is connected to the bearing platform 12.

[0077] Furthermore, the number of the bearing slide rails 15 is two, and the two bearing slide rails 15 are arranged on both sides of the bearing platform 12; at least two bearing sliders 14 are slidably arranged on the same bearing slide rail 15 to ensure more balanced support for the bearing platform 12 and ensure the stability of the movement of the bearing platform 12.

Furthermore, the feed belt 135 is arranged in the same direction as the bearing slide rail 15, and the feed belt 135 is arranged at the middle position of the bearing slide rails 15 on both sides to ensure that the pulling force applied by the feed belt 135 to the bearing platform 12 acts evenly on the bearing slide rails 15 on both sides, avoiding the feed belt 135 from generating torque load on the bearing platform 12, and ensuring the reliability of the use of the bearing platform 12.

[0078] Furthermore, the bearing slide rail 15 includes a stabilizing portion 151, a load-sharing portion 152 and a guiding portion 153. The stabilizing portion 151 is in the shape of a rectangular straight plate, connected to the base frame 11, and the extending plane where the stabilizing portion 151 is located is parallel to the extending plane where the bearing platform 12 is located, and the stabilizing portion 151 is used to stably support the bearing slide rail 15 on the base frame 11. The load-sharing portion 152 extends from the stabilizing portion 151 toward the bearing platform 12, and the load-sharing portion 152 is arranged between the stabilizing portion 151 and the guiding portion 153. The guiding portion 153 is arranged on a side of the load-sharing portion 152 away from the stabilizing portion 151, and the guiding portion 153 is embedded in the bearing slider 14. In this embodiment, a guiding groove 141 is arranged on the bearing slider 14; the guiding groove 141 is arranged in the shape of a groove on a side of the bearing slider 14 close to the bearing slide rail 15, and the guiding portion 153 is embedded in the guiding groove 141. A hook block 145 is provided in the guide groove 141; the hook block 145 is abutted against the load-sharing portion 152. By abutting the guide portion 153 against the inner wall of the guide groove 141 and the hook block 145 against the load-sharing portion 152, the joint area between the bearing slide rail 15 and the bearing slider 14 is increased, thereby improving the pressure-bearing performance between the bearing slide rail 15 and the bearing slider 14, thereby increasing the load limit of the bearing platform 12 and ensuring the stability of the operation of the bearing platform 12. The main reason why the belt conveyor structure is mainly used in the existing structure is that the belt structure has a certain flexibility and can withstand the impact load of the package during the stamping and bonding process; the bearing platform 12 in the present application adopts a rigid structure that can withstand the impact load. During the test, it was found that the guide components are easily damaged. Therefore, the present application improves the design of the bearing rail 15 and the bearing slider 14. The guide part 153 abuts against the inner wall of the guide groove 141, and the hook block 145 abuts against the load-sharing part 152, thereby improving the performance of the bearing rail 15 and the bearing slider 14 in bearing the impact load, thereby ensuring the feasibility and reliability of the bearing platform 12 in conveying the package.

[0079] Furthermore, pressure relief surfaces 155 are provided on both sides of the load-sharing portion 152. The pressure relief surfaces 155 on both sides are inclined and gradually approach each other in the direction from the stabilizing portion 151 to the guide portion 153.

The pressure relief surface 155 makes the hook block 145 contact the load-sharing portion 152 in an inclined posture, and the positive impact force borne by the bearing platform 12 will generate a part of the horizontal component force through the inclined pressure relief surface 155, and the positive pressure between the bearing slide rail 15 and the bearing slider 14 is reduced by means of the component force, so as to further improve the performance of the bearing slide rail 15 and the bearing slider 14 in bearing the impact load, and improve the reliability of the bearing platform 12 in conveying the packages.

[0080] Furthermore, the guide portion 153 is arranged in a cylindrical structure, and the guide groove 141 is in an arc-shaped groove. The guide portion 153 is fitted with the inner wall of the guide groove 141. By fitting the guide portion 153 with the inner wall of the guide groove 141 in an arc-shaped structure, compared with the existing planar fitting structure, the arc-shaped structure can increase the force bearing area between the bearing slide rail 15 and the bearing slider 14 that withstands the positive pressure, further improve the performance of the bearing slide rail 15 and the bearing slider 14 in bearing impact loads, and thereby improve the reliability of the bearing platform 12 in transporting the packages.

[0081] Furthermore, the gluing mechanism 20 is set above the carrying platform 12. When the carrying platform 12 conveys the package and passes through the gluing mechanism 20, the gluing mechanism 20 will apply glue to the upper surface of the package on the mold 16 to ensure the subsequent bonding operation of the package. Since the upper surface of the package needs to be level during the gluing process, the gluing can be evenly applied. The mold 16 can be used to support the package, which can ensure that the lower surface of the package is not flat, and the upper surface can be made level by the support of the mold 16, thereby achieving a uniform upper surface gluing operation for the package with an uneven lower surface.

A glue dropping area 225 is arranged between the glue spreading roller 231 and the glue coating roller 222. The amount of glue in the glue dropping area 225 will directly affect the completeness of the glue coating roller 222. The glue spreading roller 231 is used to evenly apply the glue in the glue dropping area 225 to the glue coating roller 222 in a rolling manner. The glue injection assembly 24 corresponds to the setting position of the glue dropping area 225, and the glue injection assembly 24 is used to inject the glue into the glue dropping area 225. Among them, the top of the glue coating roller 222 close to the glue injection assembly 24 is flush with the top of the glue spreading roller 231 close to the glue injection assembly 24. The top of the glue coating roller 222 is flush with the top of the glue leveling roller 231, which can maximize the glue capacity of the glue landing area 225, thereby improving the integrity of the glue leveling roller 231 covering the glue on the glue coating roller 222. The glue leveling roller 231 and the glue coating roller 222 are adjusted from being flush with the axis to being flush with the top without increasing the structure and parts, thereby increasing the glue capacity of the glue landing area 225 without increasing the cost, thereby improving the bonding effect of the packaging.

[0119] Furthermore, two first alignment holes 4621 are provided on the four sides of the rectangular outer ring portion 462, and the two first alignment holes 4621 on each side are symmetrical relative to the center position of the side, so as to ensure that the outer edge of the package is adsorbed evenly and improve the stability of the adsorption of the package.

The extension direction of the first strip hole 475 is perpendicular to the extension direction of the first alignment hole 4621, so as to ensure that the first alignment hole 4621 adjusts the circumferential position of the first air nozzle 472 on the outer ring part 462, and the first strip hole 475 adjusts the radial position of the first air nozzle 472 on the outer ring part 462, thereby realizing all-round adjustment of the first air nozzle 472 and ensuring adaptability to the adsorption of packages with different outer edge shapes and sizes.

[0123] In summary, the embodiment of the utility model provides a fully automatic composite laminating machine 100, which has the following beneficial effects:

[0124] The first workpiece is conveyed by the loading mechanism 10, and the gluing mechanism 20 glues the conveyed first workpiece. The feeding mechanism 30 then provides the second workpiece to the transfer mechanism 40. The transfer mechanism 40 bonds the second workpiece with the glued first workpiece, thereby realizing the automated bonding operation of the two-piece packaging of the first workpiece and the second workpiece, saving manpower and improving bonding efficiency.

[0125] The carrying platform 12 is driven to move by the feeding drive 13 to convey the first workpiece, i.e., the package. The carrying platform 12 can install and fix the mold 16, and then the package can be placed in the mold 16. The package is supported horizontally and stably on the carrying platform 12 through the mold 16, ensuring that the loading mechanism 10 can horizontally and stably convey the non-planar package, eliminating the limitations of the traditional belt structure on the package conveying and improving the adaptability of the loading mechanism 10.

[0126] By setting pressure relief surfaces 155 on both sides of the load-sharing portion 152, and tilting the pressure relief surfaces 155 on both sides so as to gradually approach each other from the stabilizing portion 151 toward the guiding portion 153, the hook block 145 is pressed against the pressure relief surface 155 of the load-sharing portion 152, so that the impact load borne by the supporting platform 12 can be converted into a part of the horizontal component through the tilted setting of the pressure relief surface 155, thereby reducing the positive pressure between the supporting slider 14 and the supporting slide rail 15, thereby increasing the load limit of the supporting platform 12 and ensuring the reliability of the supporting platform 12 in the subsequent process of bonding the packaging.

[0127] By arranging the top of the glue coating roller 222 and the glue leveling roller 231 close to the glue injection assembly 24 flush, the glue capacity of the glue drop zone 225 is increased without changing the structure of the glue coating roller 222, so as to ensure that the glue liquid coated on the glue coating roller 222 by the glue leveling roller 231 is more complete during the rotation of the glue coating roller 222 and the glue leveling roller 231, thereby making the glue liquid coated on the package by the glue coating roller 222 more uniform, thereby improving the bonding effect of the package. In addition, by arranging the top of the glue coating roller 222 and the glue leveling roller 231 flush, the height position of the glue drop zone 225 can be increased, and then by utilizing the downward flow characteristic of the glue liquid, the glue leveling roller 231 can better evenly coat the glue liquid on the glue coating roller 222, thereby further ensuring the bonding effect of the package.

[0128] When the glue coating mechanism 20 is started, the glue is in the state of being bonded between the glue coating roller 222 and the glue leveling roller 231, so a large impact load will be generated between the glue coating roller 222 and the glue leveling roller 231 when it starts to rotate. By rotating the glue leveling roller 231 and the glue leveling slide 233, the glue leveling slide 233 is slid onto the mounting frame 232, and the glue leveling slide 233 is elastically pressed by the elastic member 235 and the pressing block 234, so that the impact load during startup can be unloaded by the glue leveling slide 233 moving and compressing the elastic member 235, thereby avoiding damage to the rotating connection position of the glue leveling roller 231 and improving the reliability of the glue coating mechanism 20.

[0129] The roller plate 22222 is supported by providing an end plate 22221, and a cavity 22225 is formed between the roller plate 22222 and the central axis 2221, thereby reducing the heat transfer efficiency from the roller plate 22222 to the central axis 2221. Furthermore, in the process of coating the packaging with glue, the thermal insulation performance of the contact position between the outer side of the roller plate 22222 and the glue is improved, thereby preventing the glue from solidifying and adhering to the outer side of the rubber roller, avoiding the waste of glue, and eliminating the need for regular cleaning and maintenance of the rubber roller, thereby reducing production costs.

[0130] By providing support by ribs 2223 between the central axis 2221 and the roller plate 22222, the bearing capacity of the roller plate 22222 is improved, and deformation of the roller plate 22222 due to the provision of the cavity 22225 is avoided, which makes it impossible to evenly apply glue to the package. By providing the ribs 2223 structure, the feasibility of the cavity 22225 structure is ensured, and the deformation resistance of the roller plate 22222 is improved, thereby ensuring the stability of the roller plate 22222 in applying glue to the package.

[0131] By setting the first adjustment hole 3215 and the second adjustment hole 3216 on the feeding table 321, and the first adjustment hole 3215 and the second adjustment hole 3216 are alternately arranged in the first direction and spaced apart in the second direction, and by setting the assembly hole 335 on the film guide frame 33, at least part of the first adjustment hole 3215 and the second adjustment hole 3216 are overlapped with the assembly hole 335, so that the installation position and installation direction of the film guide frame 33 on the feeding table 321 are adjustable, and the film guide frame 33 can be used to enclose packages of different specifications and shapes, thereby ensuring that the packages are stacked on the feeding table 321, and there is no need to set up film guide frames 33 of multiple specifications, thereby improving the adaptability of the film guide frame 33 to stacking packages of different specifications and shapes, and reducing production costs.

[0132] By arranging the first feeding part 3211 and the second feeding part 3212 on the feeding table 321, and switching the first feeding part 3211 or the second feeding part 3212 to correspond to the feeding position through the material placement driving part 322, it is possible to achieve that when one of the first feeding part 3211 and the second feeding part 3212 is feeding, the other can be loaded with packages, so as to ensure that there is no need to stop the machine for loading when loading packages, thereby improving production efficiency.

[0133] By arranging the first adjustment hole 3215 and the second adjustment hole 3216 in a staggered manner in the second direction, the length dimension L of the first adjustment hole 3215 and the second adjustment hole 3216 is greater than or equal to the spacing H, the length dimension of the two assembly holes 335 on the film guide frame 33 is equal to L, and the spacing between the two assembly holes 335 is equal to H, so that the arrangement position and rotation angle of the film guide frame 33 on the feed table 321 are adjustable, ensuring that the film guide frame 33 can fix packages of different specifications and shapes, thereby greatly improving the adaptability of the film guide frame 33.

[0134] By installing the transfer slide 43 and the transfer drive 44 on the beam 42, and arranging a top support part 422 and a bottom support part 423 on the beam 42 to reinforce the installation part 424, the load-bearing performance of the beam 42 is improved, and the deformation of the beam 42 due to long-term impact load and torque is avoided, thereby ensuring the alignment accuracy between the packages and improving the bonding effect.

[0135] By providing a positioning groove 4111 on the positioning plate 411 and providing an embedded portion 421 on the crossbeam 42, the crossbeam 42 is positioned relative to the installation position of the transfer bracket 41 by embedding the embedded portion 421 into the positioning groove 4111, and no additional leveling and calibration operations are required, thereby improving assembly accuracy and assembly efficiency. In addition, the embedded fixing structure can also improve the reliability of assembly between the positioning plate 411 and the crossbeam 42. The positioning plate 411 can also absorb a part of the load borne by the crossbeam 42, thereby reducing the load impact borne by the transfer bracket 41, preventing the transfer bracket 41 from deforming and affecting the alignment accuracy between the packages, and further improving the bonding effect between the packages.

[0136] By configuring the mounting disk 46 with an outer ring portion 462 surrounding the outer side of the inner ring portion 461, and then connecting the inner ring portion 461 and the outer ring portion 462 via the connecting portion 463, the first adjusting block 471 adjusts the setting position of the first air nozzle 472 circumferentially along the outer ring portion 462, and the second adjusting block 481 adjusts the setting position of the second air nozzle 482 radially along the connecting portion 463. The first air nozzle 472 and the second air nozzle 482 cooperate to adsorb and grasp the package, thereby achieving all-round adjustment in the circumferential and radial directions to meet the grasping requirements of packages of different structures and sizes, thereby improving adaptability of use, and there is no need to replace the mounting disk 46 when grasping packages of different specifications, thereby reducing processing costs and improving processing efficiency.

[0137] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0138] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
