Description

Technical Field

[0001] This utility model relates to the field of optical adhesive bonding technology, specifically to an optical adhesive bonding machine. Background Technology

[0002] With the rapid development of industries such as consumer electronics, smart cars, and flexible displays, optical adhesive bonding technology, as a core process for achieving high-quality display and touch experiences, is becoming increasingly important. This technology is widely used in the lamination bonding of various optical components such as displays, touchscreens, and glass covers, directly determining the overall performance of the final product in terms of visual effects, structural strength, and reliability. Against this backdrop, the market has placed unprecedented demands on the capacity efficiency, processing precision, and production line flexibility of optical adhesive bonding equipment.

[0003] In existing technologies, optical adhesive laminating machines generally use fixed or single-motion worktables for loading, laminating, and unloading operations. These traditional machines have a significant efficiency bottleneck: the loading, laminating, and unloading processes must be performed sequentially, forming a serial workflow. This means that when the machine is performing the core laminating process, the loading and unloading stations are idle and waiting, which severely restricts the overall machine cycle time due to non-productive time, making it difficult to effectively improve production efficiency. In addition, the loading mechanism of traditional equipment is usually designed for specific types of raw materials, and the position and size of its suction head are fixed, lacking flexible adjustment capabilities. When faced with raw materials of different sizes or types, it is necessary to stop the machine and perform cumbersome manual adjustments or change the fixture, which not only increases the complexity of operation and prolongs the equipment preparation time, but also reduces the flexibility of the production line and its ability to handle multi-variety, small-batch orders. To address this, we propose an optical adhesive laminating machine. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides an optical adhesive bonding machine, comprising a mounting frame and a positioning stage. The positioning stage has four symmetrically distributed adjusting blocks, and two symmetrically distributed vacuum suction cups are fixedly mounted on each of the four adjusting blocks. The positioning stage is rotatably connected to the mounting frame via a mounting shaft. A gear is sleeved on the mounting shaft. A rack is slidably mounted inside the mounting frame, and the rack meshes with the gear. A first cylinder is fixedly mounted inside the mounting frame, and the rack is fixedly connected to the output end of the piston rod of the first cylinder.

[0005] In some embodiments, four sets of symmetrically distributed positioning blocks are slidably installed in the mounting frame, and four sets of symmetrically distributed positioning slots are provided on the positioning platform. All four sets of positioning blocks are movably engaged with the positioning platform through the positioning slots. Two sets of symmetrically distributed first push rods and two sets of symmetrically distributed second push rods are slidably installed in the mounting frame.

[0006] In some embodiments, the two sets of first push rods and second push rods are vertically distributed, and the four sets of positioning blocks are slidably connected to a corresponding set of first push rods and a corresponding set of second push rods, respectively. The two sets of first push rods and the two sets of second push rod brackets are each equipped with two sets of symmetrically distributed second cylinders, and the first push rods and second push rods are respectively fixedly connected to the output end of the corresponding second cylinder piston rod.

[0007] In some embodiments, the positioning platform is provided with an adjustment mechanism for adjusting the position of four sets of adjustment blocks. The adjustment mechanism includes two sets of first adjustment rods symmetrically distributed in the positioning platform and two sets of second adjustment rods symmetrically distributed in the positioning platform. The two sets of first adjustment rods and the two sets of second adjustment rods are vertically distributed.

[0008] In some embodiments, the four sets of adjustment blocks are slidably connected to a corresponding set of first adjustment rods and a set of second adjustment rods, respectively. The positioning platform is provided with a first bidirectional lead screw and a second bidirectional lead screw.

[0009] In some embodiments, both ends of the first bidirectional lead screw pass through the positioning table and are rotatably connected to the positioning table via rolling bearings. Both ends of the first bidirectional lead screw pass through two sets of first adjusting rods and are threadedly connected to the two sets of first adjusting rods respectively.

[0010] In some embodiments, the two ends of the second bidirectional lead screw pass through the positioning table and are rotatably connected to the positioning table via rolling bearings. The two ends of the second bidirectional lead screw pass through two sets of second adjusting rods and are threadedly connected to the two sets of second adjusting rods respectively.

[0011] This utility model has at least the following beneficial effects: 1. By integrating rotary positioning and multi-directional locking mechanisms, the production efficiency and operational precision of the equipment are significantly improved. The rack and pinion mechanism driven by the first cylinder drives the positioning table to rotate precisely on the mounting frame, realizing rapid switching between loading, bonding, and unloading stations. This transforms the previously sequential processes into parallel or overlapping operations, effectively shortening the equipment cycle time and reducing non-productive waiting time. At the same time, the movable engagement of multiple symmetrically distributed positioning blocks and positioning slots, along with the precise control of the positioning blocks by the first and second push rods driven by the second cylinder, ensures that the positioning table can achieve stable and reliable locking when stopped at any angle. This greatly improves the positional accuracy and repeatability of the bonding process, providing a guarantee for high-quality bonding.

[0012] 2. By driving two sets of first and second adjusting rods to move in opposite directions via the first and second bidirectional lead screws respectively, the four sets of adjusting blocks can be flexibly and independently adjusted in two dimensions within the positioning table. This design allows the vacuum suction cup assembly mounted on the adjusting blocks to adapt to raw materials of different sizes and types, realizing the transformation of the feeding mechanism from a fixed to a flexible one. When facing multi-variety, small-batch production tasks, there is no need to stop the machine to change fixtures or make complex manual adjustments. The adsorption layout can be quickly changed simply by adjusting the lead screws, significantly shortening the equipment changeover time, enhancing the flexibility and market responsiveness of the production line, and reducing fixture inventory and management costs.

[0015] 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.

[0016] Example 1: Please refer to Figure 1-3This utility model provides a technical solution: an optical adhesive bonding machine, including a mounting frame 1 and a positioning table 2. The positioning table 2 is provided with four sets of symmetrically distributed adjusting blocks 301. Two sets of symmetrically distributed vacuum suction cups 302 are fixedly installed on each of the four sets of adjusting blocks 301. The positioning table 2 is rotatably connected to the mounting frame 1 through a mounting shaft 4. A gear 5 is sleeved on the mounting shaft 4. A rack 6 is slidably installed in the mounting frame 1. The rack 6 is meshed with the gear 5. A first cylinder 7 is fixedly installed in the mounting frame 1. The rack 6 is fixedly connected to the output end of the piston rod of the first cylinder 7. When a work position needs to be switched, the piston rod of the first cylinder 7 extends or retracts, driving the rack 6 to move linearly. The rack 6 meshes with the gear 5 fixed on the mounting shaft 4, converting the linear motion into the rotational motion of the gear 5, thereby driving the entire positioning table 2 to rotate precisely around the mounting shaft 4, realizing rapid switching between work positions such as loading, bonding, and unloading.

[0017] Four sets of symmetrically distributed positioning blocks 9 are slidably installed inside the mounting bracket 1. Four sets of symmetrically distributed positioning slots 8 are provided on the positioning platform 2. All four sets of positioning blocks 9 are movably engaged with the positioning platform 2 through the positioning slots 8. Two sets of symmetrically distributed first push rods 10 and two sets of symmetrically distributed second push rods 11 are slidably installed inside the mounting bracket 1. The two sets of first push rods 10 and second push rods 11 are perpendicularly distributed. The four sets of positioning blocks 9 are slidably connected to a corresponding set of first push rods 10 and a corresponding set of second push rods 11, respectively. Two sets of brackets are installed for each set of first push rods 10 and each set of second push rods 11. The symmetrically distributed second cylinders 12, the first push rod 10 and the second push rod 11 are respectively fixedly connected to the output end of the piston rod of the corresponding second cylinder 12. When the positioning table 2 rotates to the target position, the two sets of second cylinders 12 drive the first push rod 10 and the second push rod 11 to move in the vertical direction respectively. The linkage of the first push rod 10 and the second push rod 11 will push the four sets of positioning blocks 9 that are slidably connected to them to extend synchronously and insert into the corresponding positioning grooves 8 on the side of the positioning table 2 to form a multi-point snap-fit, thereby firmly locking the positioning table 2 at the current angle, preventing it from shifting during the fitting process, and ensuring processing accuracy.

[0018] Example 2: Please refer to Figure 4 , Figure 5 The positioning platform 2 is equipped with an adjustment mechanism 3 for adjusting the position of four sets of adjustment blocks 301. The adjustment mechanism 3 includes two sets of first adjustment rods 303 symmetrically distributed in the positioning platform 2, and two sets of second adjustment rods 305 symmetrically distributed in the positioning platform 2. The two sets of first adjustment rods 303 and the two sets of second adjustment rods 305 are vertically distributed. The vertically distributed first adjustment rods 303 and second adjustment rods 305 together form a two-dimensional planar adjustment frame. By driving these two sets of adjustment rods, the adjustment blocks 301 fixed on them can be moved in the plane, laying the foundation for adapting to raw materials of different sizes.

[0019] The four sets of adjustment blocks 301 are slidably connected to a corresponding set of first adjustment rods 303 and a set of second adjustment rods 305. A first bidirectional lead screw 304 and a second bidirectional lead screw 306 are provided inside the positioning platform 2. The two ends of the first bidirectional lead screw 304 pass through the positioning platform 2 and are rotatably connected to it via rolling bearings. The two ends of the first bidirectional lead screw 304 pass through two sets of first adjustment rods 303 and are threadedly connected to them respectively. The two ends of the second bidirectional lead screw 306 pass through the positioning platform 2 and are rotatably connected to it via rolling bearings. The two ends of the second bidirectional lead screw 306 pass through two sets of second adjustment rods 305 and are threadedly connected to them respectively. When the first bidirectional lead screw 304 is rotated, because the threads at its two ends rotate in opposite directions, it will drive the two sets of first adjustment rods 303 to move towards or away from each other along the X-axis. Similarly, rotating the second bidirectional lead screw 306 will drive the two sets of second adjustment rods 305 to move along the Y-axis. Each adjusting block 301 is simultaneously slidably connected to a first adjusting rod 303 and a second adjusting rod 305. Therefore, under the coordinated drive of the lead screws in both directions, it can move to any position in the plane of the positioning table 2, thereby driving the vacuum suction cups 302 on it to adjust to a position that matches the size of the raw material to be bonded, thus achieving rapid shape change.
