Description

Technical Field

[0001] This utility model relates to the field of sheet assembly technology, specifically to an automatic sheet assembly machine. Background Technology

[0002] In current industrial production, sheet assembly often relies on manual operation, which not only affects assembly efficiency but also increases labor costs. Specifically, traditional sheet assembly methods mainly depend on manual labor using positioning fixtures to assemble sheets one by one onto the conveyor belt. This method has several significant problems:

[0003] First, manual assembly is relatively inefficient. Because it requires manual operation of each component, the assembly speed is limited by the operator's skill level and physical condition, making it difficult to significantly improve production efficiency.

[0004] Secondly, the use of positioning fixtures during manual assembly may deform the positioning holes of the strip. After prolonged use, the accuracy and stability of the positioning fixtures may decrease, leading to deformation of the strip positioning holes and consequently affecting the quality and reliability of the product.

[0005] Furthermore, with the continuous development of industrial automation technology, people have increasingly higher requirements for production efficiency and product quality. Traditional manual assembly methods can no longer meet the needs of modern industrial production, thus necessitating the search for a more efficient and accurate automated assembly solution.

[0006] To address the aforementioned issues, the market urgently needs an automated sheet assembly machine capable of automatically completing processes such as sheet feeding, film peeling, alignment, conveying, and visual inspection. This automated assembly machine can not only significantly improve production efficiency and reduce labor costs, but also minimize quality problems caused by improper human operation through precise automated control. Utility Model Content

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic sheet assembly machine, including an equipment cabinet, in which a sheet feeding unit is installed and fixed, and the upper part of the equipment cabinet is respectively installed and fixed with a first-section robotic arm unit, a film tearing unit, an alignment unit, a second-section robotic arm unit, a material pulling unit, a conveying unit, and a vision inspection unit.

[0009] Furthermore, a material release unit is installed and fixed on the front side of the equipment cabinet, and a blue paper release unit and a finished product winding unit are installed and fixed on the rear side respectively.

[0010] Furthermore, the sheet feeding unit includes a feeding and lifting linear drive module installed inside the equipment cabinet. The drive end of the feeding and lifting linear drive module is fixed with a lifting bracket, and the sheets are stacked on the upper part of the lifting bracket.

[0012] Furthermore, the segmented robotic arm unit includes a segmented transverse linear drive module installed on the upper part of the equipment cabinet, and a segmented material handling module is fixedly installed on the drive end of the segmented transverse linear drive module.

[0013] Furthermore, the section material handling module includes a material handling drive cylinder installed on the drive end of the section transverse linear drive module. A lifting plate is installed and fixed at the telescopic end of the material handling drive cylinder, and a damper is installed and fixed at the bottom end of the lifting plate. The buffer end at the bottom of the damper is connected to the suction plate.

[0014] Furthermore, the suction plate has a pre-drilled alignment hole inside, the inside of the suction plate is a hollow structure, and the bottom of the suction plate has several suction holes that communicate with the hollow structure.

[0015] Furthermore, the film-tearing unit includes a film-tearing platform installed on the upper part of the equipment cabinet, with a waiting platform connected and fixed at the end of the film-tearing platform, and a film-tearing plate installed and fixed on the upper part of the film-tearing platform.

[0016] Furthermore, the film-tearing platform is internally rotatably connected to a film-tearing active roller shaft and a film-tearing driven roller shaft, and a film-tearing drive motor is installed and fixed on the outside of the film-tearing platform. The drive end of the film-tearing drive motor extends into the interior of the film-tearing platform and is connected and fixed to the film-tearing active roller shaft.

[0017] Furthermore, a receiving roller shaft is rotatably connected below the film-tearing platform, and the film-tearing active roller shaft and the receiving roller shaft are connected by a receiving belt pulley group for transmission.

[0018] This invention provides an automatic sheet assembly machine. Compared with the prior art, it has the following advantages:

[0019] 1. Significantly Improved Production Efficiency: Through an integrated automated assembly process, including multiple stages such as material feeding, film removal, alignment, conveying, and visual inspection, rapid and accurate assembly of sheets is achieved. Compared to manual operation, this automated production method can significantly improve production efficiency, shorten the production cycle, and meet the demands of modern industrial production for high efficiency and speed.

[0020] 2. Improved Product Quality: Automated assembly machines, through precise mechanical control and visual inspection systems, ensure that each sheet is accurately placed on the conveyor belt, avoiding errors and deformation problems that may occur with manual operation. This not only improves the product qualification rate but also reduces rework and scrap costs caused by quality issues.

[0021] 3. Reduced Costs: The use of automated assembly machines can significantly reduce labor costs and decrease reliance on operators. At the same time, increased production efficiency and fewer quality issues also reduce the consumption of raw materials and energy, further lowering production costs. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-11This utility model provides a technical solution: an automatic sheet assembly machine, including a cabinet 1. A sheet feeding unit 2 is installed and fixed inside the cabinet 1, and a first-section robotic arm unit 3, a film-tearing unit 4, an alignment unit 5, a second-section robotic arm unit 6, a pulling unit 7, a conveying unit 8, and a vision inspection unit 9 are respectively installed and fixed on the upper part of the cabinet 1. The cabinet 1 can release the material belt and blue separator paper and rewind the finished product. The sheet feeding unit 2 can provide the sheet required by the machine. The first-section robotic arm unit 3 can transfer the sheet provided by the sheet feeding unit 2 to the film-tearing unit 4. The film-tearing unit 4 can tear off the bottom film on the sheet. The second-section robotic arm unit 6 can transfer the film-teared sheet to the alignment unit 5 for positioning. The pulling unit 7 can pull the material belt released by the cabinet 1. The conveying unit 8 can intermittently convey the material belt during the assembly process. The vision inspection unit 9 can detect the position of the sheet placed on the material belt.

[0036] The front side of the equipment cabinet 1 is equipped with a material release unit 11, and the rear side is equipped with a blue paper release unit 12 and a finished product winding unit 13. The material release unit 11, the blue paper release unit 12, and the finished product winding unit 13 can perform the corresponding release of the material, release of the blue paper, and winding of the finished product. The material release unit 11, the blue paper release unit 12, and the finished product winding unit 13 have the same structure and are all driven by a motor to rotate the material tray.

[0037] The sheet feeding unit 2 includes a feeding and lifting linear drive module 21 installed inside the equipment cabinet 1. A lifting bracket 22 is installed and fixed at the drive end of the feeding and lifting linear drive module 21. Sheets are stacked on the upper part of the lifting bracket 22. Several baffles 23 are installed inside the equipment cabinet 1 and around the lifting bracket 22.

[0038] When the sheet feeding unit 2 is working, several sheet components 10 are stacked on the lifting bracket 22. Each time a sheet component 10 needs to be provided, the feeding lifting linear drive module 21 will drive the lifting bracket 22 to move upward. The height of each upward movement is set to the thickness of one sheet component 10. In this way, when the top sheet component 10 is removed, the next layer of sheet components 10 can be replenished.

[0039] The first-section robotic arm unit 3 includes a first-section transverse linear drive module 31 installed on the upper part of the equipment cabinet 1. A first-section material picking module 32 is installed and fixed at the drive end of the first-section transverse linear drive module 31. The first-section material picking module 32 includes a material picking drive cylinder 321 installed on the drive end of the first-section transverse linear drive module 31. A lifting plate 322 is installed and fixed at the telescopic end of the material picking drive cylinder 321. A damper 323 is installed and fixed at the bottom end of the lifting plate 322. The buffer end at the bottom of the damper 323 is connected to a suction plate 324. An alignment hole 325 is reserved in the interior of the suction plate 324. The interior of the suction plate 324 is a hollow structure, and several suction holes 326 connected to the hollow structure are opened at the bottom end of the suction plate 324.

[0040] When the first-section robotic arm unit 3 is working, assuming that the suction plate 324 is located directly above the sheet assembly 10, the picking drive cylinder 321 drives the lifting plate 322, damper 323, and suction plate 324 to move downward as a whole until the lower surface of the suction plate 324 contacts the sheet assembly 10. Then, the suction plate 324 generates suction on the sheet assembly 10, which can hold the sheet assembly 10. Then, the picking drive cylinder 321 retracts, driving the lifting plate 322, damper 323, and suction plate 324 to move upward as a whole. Subsequently, the first-section transverse linear drive module 31 drives the first-section picking module 32 and the sheet assembly 10 to move above the film-tearing unit 4, and similarly releases the sheet assembly 10 onto the film-tearing unit 4.

[0041] The film-tearing unit 4 includes a film-tearing platform 41 installed on the upper part of the equipment cabinet 1. The end of the film-tearing platform 41 is connected and fixed to the waiting platform 42, and the film-tearing plate 43 is installed and fixed on the upper part of the film-tearing platform 41. The film-tearing active roller shaft 44 and the film-tearing driven roller shaft 45 are rotatably connected inside the film-tearing platform 41, and the film-tearing drive motor 46 is installed and fixed on the outer side of the film-tearing platform 41. The drive end of the film-tearing drive motor 46 extends into the interior of the film-tearing platform 41 and is connected and fixed to the film-tearing active roller shaft 44. The bottom of the film-tearing platform 41 is rotatably connected to the receiving roller shaft 47. The film-tearing active roller shaft 44 and the receiving roller shaft 47 are connected by a receiving pulley set 48.

[0042] When the film-tearing unit 4 is working, the sheet assembly 10 first includes a base film 101 and a sheet 102. The sheet 102 is bonded to the upper part of the base film 101. Therefore, the sheet assembly 10 placed on the film-tearing plate 43 is a combination of the base film 101 and the sheet 102. The film-tearing drive motor 46 drives the film-tearing active roller shaft 44 to rotate, thereby pulling the base film 101 downward from the end of the film-tearing plate 43 and passing between the film-tearing active roller shaft 44 and the film-tearing driven roller shaft 45, relying on friction to solidify the film. As the film moves downward, because the hardness of the sheet 102 is greater than that of the base film 101, the sheet 102 will peel off from the base film 101 little by little. The force generated by the movement of the base film 101 will pull the sheet 102 from the film-tearing plate 43 to the waiting platform 42. During the rotation of the film-tearing active roller 44, the take-up roller 47 will also be driven to rotate through the take-up pulley group 48, thereby winding up the base film 101.

[0043] The alignment unit 5 includes an alignment platform 51 installed on the upper part of the equipment cabinet 1. An alignment protrusion 52 is fixedly installed on the upper part of the alignment platform 51. An alignment hole is pre-drilled inside the sheet 102. The alignment hole is adapted to the alignment protrusion 52. When the sheet 102 is placed on the upper part of the alignment platform 51, the alignment protrusion 52 is located in the alignment hole, thereby completing the accurate positioning of the sheet 102.

[0044] The two-section robotic arm unit 6 includes a two-section transverse linear drive module 61 installed on the upper part of the equipment cabinet 1. A two-section longitudinal linear drive module 62 is installed and fixed at the drive end of the two-section transverse linear drive module 61. A two-section first picking module 63 and a two-section second picking module 64 are respectively installed at the drive end of the two-section longitudinal linear drive module 62.

[0045] When the two-section robotic arm unit 6 is working, firstly, the structures of the first picking module 63 and the second picking module 64 of the second section are the same as those of the first picking module 32. Assuming that the first picking module 63 of the second section is located directly above the waiting platform 42, then the second picking module 64 of the second section will be located directly above the alignment unit 5. At this time, the first picking module 63 and the second picking module 64 of the second section will simultaneously pick up the sheet 102 corresponding to the waiting platform 42 and the alignment unit 5. And by adjusting the position of the second section transverse linear drive module 61 and the second section longitudinal linear drive module 62, the sheet 102 on the waiting platform 42 is placed on the alignment unit 5, and the sheet 102 on the alignment unit 5 is placed on the conveying unit 8.

[0046] The material pulling unit 7 includes a material pulling drive module 71 installed on the upper part of the equipment cabinet 1. The end of the material pulling drive module 71 is connected to a downwardly inclined transition roller shaft 72, and the bottom end of the transition roller shaft 72 is connected to a suction-feed plate 73. The suction-feed plate 73 can generate a slight suction force on the material belt released by the material belt release unit 11, but it does not affect the movement of the material belt, thereby assisting in the suction and positioning of the material belt. After passing through the suction-feed plate 73, the material belt passes through the transition roller shaft 72 and passes through the interior of the material pulling drive module 71. The material pulling drive module 71 is responsible for pulling the material belt. Specifically, the material pulling drive module 71 includes components installed and fixed in the equipment cabinet. The upper part of the equipment cabinet 1 includes a material pulling motor 711 and a material pulling drive roller 713 rotatably connected to the upper part of the equipment cabinet 1. The upper part of the material pulling drive roller 713 is equipped with a height-adjustable pressure driven roller 712, that is, the distance between the pressure driven roller 712 and the material pulling drive roller 713 is adjustable. The drive end of the material pulling motor 711 is connected to the material pulling drive roller 713 through a material pulling pulley set 714. When material needs to be pulled, the material pulling motor 711 drives the material pulling drive roller 713 to rotate through the material pulling pulley set 714. The material belt moves by relying on the friction between the material belt and the pressure driven roller 712 and the material pulling drive roller 713.

[0047] The conveying unit 8 includes a conveying platform 81 installed on the upper part of the equipment cabinet 1. The pulled material belt is located on the upper part of the conveying platform 81 and is pulled by a conveying drive module 82 installed at the end of the conveying platform 81. The structure of the conveying drive module 82 is the same as that of the material pulling drive module 71.

[0048] The vision inspection unit 9 includes a bracket 91 installed on the upper part of the equipment cabinet 1. An industrial camera 92 is fixed on the top of the bracket 91. After the two-section robot arm unit 6 places the sheet 102 on the conveyor belt, the industrial camera 92 will detect whether the placement of the sheet 102 is correct. The specific principle is existing known technology and will not be described in detail here.

[0049] Finally, it should be noted that the structures of the feeding and lifting linear drive module 21, the first-section transverse linear drive module 31, the second-section transverse linear drive module 61, and the second-section longitudinal linear drive module 62 are all the same and all adopt existing technology, which will not be described in detail here. In addition, the suction plate 324 and the air suction plate 73 generate suction force by connecting to an external air pipe, which is connected to an air extraction device.
