Description

Technical Field

[0001] This utility model relates to the field of dispensing and bonding machine technology, and more specifically, to a dispensing and bonding machine for hydrogen fuel cell production. Background Technology

[0002] Dispensing and bonding machines are highly efficient and precise automated equipment widely used in industries such as electronics manufacturing, automotive parts, and medical devices. By precisely controlling the dispensing of adhesive and the bonding of materials, they achieve high-precision and high-consistency production requirements, ensuring the airtightness of the fuel cell stack, uniform current distribution, and structural reliability. They also enable high-efficiency production, adapting to various adhesive types such as UV adhesives, hot melt adhesives, and epoxy resins, and supporting the processing of workpieces of different shapes and sizes. They are characterized by ease of operation, high stability, and high production efficiency. Equipped with an intelligent control system and vision inspection module, they ensure the accuracy of each process and product quality, significantly improving production efficiency and yield. They are an indispensable key piece of equipment in modern intelligent manufacturing.

[0003] During the production of hydrogen fuel cells, operators frequently use dispensing and bonding machines to perform dispensing operations. While existing dispensing and bonding machines possess basic dispensing functions, common issues include visual positioning lens contamination leading to feature recognition drift, and dispensing needle wear causing increased glue diameter and glue splatter. These problems result in glue being mistakenly dispensed onto the conveyor belt. Once cured, the glue adheres to the conveyor belt surface, forming an uneven, hardened layer that compromises the belt's flatness. This can cause subsequent workpiece misalignment or jamming during transport. Therefore, improvements are needed. Utility Model Content

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.

[0023] like Figures 1 to 6 As shown, this utility model provides a dispensing and bonding machine for hydrogen fuel cell production, including a first mounting frame 1, a second mounting frame 2 movably connected to the back of the first mounting frame 1, a first motor 3 fixedly connected to the bottom of the first mounting frame 1, a first rotating shaft 4 fixedly sleeved at the other end of the output shaft of the first motor 3, a rotating rod 5 fixedly sleeved on the outer surface of the first rotating shaft 4, a hollow rod 6 movably connected to the outer surface of the rotating rod 5, an L-shaped rod 7 fixedly connected to the back of the hollow rod 6, and the side of the L-shaped rod 7 away from the hollow rod 6 fixedly connected to the bottom of the second mounting frame 2. A fixing sleeve 9 and a rectangular rod 8 are fixedly connected to the bottom of the first mounting frame 1 and the second mounting frame 2, respectively. The outer surface of the rectangular rod 8 is movably sleeved with the inner surface of the fixing sleeve 9. Rollers 10 are movably installed on both sides of the bottom of the first mounting frame 1 and the second mounting frame 2.

[0024] When the first motor 3 starts running, it will cause the first rotating shaft 4 to drive the rotating rod 5 to rotate. At this time, the rotating rod 5 will squeeze and push the hollow rod 6, causing the hollow rod 6 to drive the L-shaped rod 7 to move horizontally. This will cause the second mounting bracket 2 to drive the rectangular rod 8 to move synchronously under the limiting action of the fixed sleeve 9.

[0025] The outer surface of the first mounting frame 1 is fixedly connected to the second motor 11. The other end of the output shaft of the second motor 11 is fixedly sleeved with the second rotating shaft 12. The side of the second rotating shaft 12 away from the second motor 11 passes through the first mounting frame 1 and extends to the outside of the first mounting frame 1, and is fixedly connected to the spline shaft 13. The outer surface of the spline shaft 13 is fixedly sleeved with the drive roller 14. The side of the drive roller 14 away from the spline shaft 13 is movably sleeved with the inner surface of the second mounting frame 2.

[0026] When the second motor 11 starts running, the second rotating shaft 12 will drive the spline shaft 13 and the drive roller 14 to rotate under the limiting action of the second mounting frame 2.

[0027] The inner surface of the second mounting frame 2 is movably sleeved with a driven roller 15 located to the right of the driving roller 14. The side of the driven roller 15 away from the second mounting frame 2 is movably sleeved with the inside of the first mounting frame 1. The driven roller 15 is connected to the driving roller 14 via a conveyor belt 16.

[0028] When the drive roller 14 rotates, it will drive the driven roller 15 to rotate synchronously via the conveyor belt 16.

[0029] The bottom of the first mounting bracket 1 and the second mounting bracket 2 are fixedly connected to a rectangular plate 17. A servo motor 18 is fixedly connected to the outside of the rectangular plate 17. The other end of the output shaft of the servo motor 18 is fixedly sleeved with a first threaded rod 19. The side of the first threaded rod 19 away from the servo motor 18 passes through the rectangular plate 17 and extends into the interior of the rectangular plate 17 and is threadedly sleeved with a sliding block 20. There are two sliding blocks 20. The tops of the two sliding blocks 20 are movably connected to the bottom of the first mounting bracket 1 and the second mounting bracket 2, respectively. The tops and bottoms of the first mounting bracket 1 and the second mounting bracket 2 are fixedly connected to mounting sleeves 23.

[0030] When the servo motor 18 starts running, it will cause the first threaded rod 19 to rotate, thereby causing the two sliding blocks 20 to move horizontally to the left under the limiting action of the first mounting bracket 1 and the second mounting bracket 2 respectively.

[0031] Among them, the outer surface of the sliding block 20 is hinged with a diagonal rod 21, the outer surface of the diagonal rod 21 is hinged with a C-shaped plate 22, the outer surface of the C-shaped plate 22 is movably sleeved with the inner surface of the mounting sleeve 23, and the other end of the C-shaped plate 22 is fixedly connected with a guide plate 24.

[0032] When the sliding block 20 moves to the left, the inclined rod 21 will start to move. At this time, the two C-shaped plates 22 will drive the two guide plates 24 to move horizontally towards each other under the limiting action of the mounting sleeve 23.

[0033] The top of the first mounting bracket 1 and the second mounting bracket 2 are respectively fixedly connected to the connecting bracket 26 and the vertical plate 32. The left side of the vertical plate 32 is fixedly connected to the mounting plate 25, and the outer surface of the mounting plate 25 is movably sleeved with the inner surface of the connecting bracket 26.

[0034] When the second mounting bracket 2 moves, the vertical plate 32 will cause the mounting plate 25 to slide outward along the inner surface of the connecting bracket 26 under the limiting action of the connecting bracket 26.

[0035] Among them, a drive motor 27 is fixedly connected to the front of the connecting frame 26, and a second threaded rod 28 is fixedly sleeved at the other end of the output shaft of the drive motor 27. The other end of the second threaded rod 28 passes through the connecting frame 26 and extends into the interior of the connecting frame 26 and is threadedly sleeved with a movable frame 29. The top of the movable frame 29 is movably connected to the inner surface of the connecting frame 26, and a vision camera 30 is fixedly connected to the bottom of the movable frame 29. A dotted needle 31 is fixedly sleeved on the left side of the movable frame 29.

[0036] When the drive motor 27 starts running, it will cause the second threaded rod 28 to rotate. At this time, the moving frame 29 will drive the vision camera 30 and the dispensing needle 31 to move horizontally back and forth under the limiting action of the connecting frame 26.

[0037] Working principle and usage process of this utility model:

[0038] First, the second motor 11 is started, causing the second rotating shaft 12 to drive the splined shaft 13 and the driving roller 14 to rotate synchronously. This, in turn, drives the driven roller 15 to rotate via the conveyor belt 16, thus initiating material transport. When the battery is transported to below the dispensing needle 31, and the vision camera 30 detects a tilt in the battery's posture, the servo motor 18 is started, causing the first threaded rod 19 to rotate. At this point, under the limiting action of the first mounting bracket 1 and the second mounting bracket 2, the two sliding blocks 20 will move horizontally to the left synchronously, causing the two inclined rods 2... When movement occurs, under the limiting action of the mounting sleeve 23, the two C-shaped plates 22 will drive the two guide plates 24 to move horizontally towards each other, thereby realizing the function of adjusting the distance between the two guide plates 24. This allows the device to center and align the hydrogen fuel cell on the conveyor belt 16, preventing the hydrogen fuel cell from tilting during transportation and affecting the subsequent dispensing effect. Then, by starting the drive motor 27, the dispensing needle 31 is adjusted to adjust its horizontal position, and together with the conveyor belt 16, the dispensing operation of the hydrogen fuel cell is realized.

[0039] When the conveyor belt 16 needs to be disassembled and cleaned after long-term use due to glue adhering to its surface due to accidental application, the first motor 3 is started, causing the first rotating shaft 4 to rotate the rotating rod 5. The rotating rod 5 then squeezes and pushes the hollow rod 6, causing the hollow rod 6 to drive the L-shaped rod 7 to move horizontally backward. This causes the second mounting frame 2 to drive the rectangular rod 8 to move backward synchronously under the limiting action of the fixed sleeve 9, and slide outward through the roller 10. Finally, when the driving roller 14 and the driven roller 15 are disengaged from the interior of the second mounting frame 2, the conveyor belt 16 can be easily disassembled and cleaned by the operator, thus improving the efficiency of the operator in disassembling and assembling the conveyor belt 16.
