Description

Technical Field

[0001] This utility model relates to the field of optical adhesive punching, and specifically to an optical adhesive punching mechanism. Background Technology

[0002] In the manufacturing fields of electronics and display panels, optical adhesives are important bonding materials, and the precision and efficiency of their die-cutting process directly affect the quality of end products and production schedules. Currently, optical adhesive die-cutting mainly relies on die-cutting mechanisms. Traditional die-cutting mechanisms typically include basic structures such as a worktable, column, top beam, and cutter head assembly, which perform the die-cutting operation on the optical adhesive by driving the cutter head downwards.

[0003] However, existing punching mechanisms have significant limitations in practical applications. On the one hand, for optical adhesive products of different specifications and sizes, the spacing between the cutter heads needs to be frequently adjusted to match the punching requirements, but traditional mechanisms mostly use manual adjustment or fixed spacing designs. When adjusting manually, operators need to loosen the cutter head fixing parts one by one, measure the spacing, and then re-fix them, which is not only time-consuming and labor-intensive, but also easily leads to the accumulation of spacing errors after multiple adjustments, seriously affecting the punching accuracy. Fixed spacing designs can only be adapted to a single specification of product, and when facing diverse production needs, the entire cutter head assembly needs to be replaced, which greatly increases equipment costs and changeover time. On the other hand, the stability of the cutter head movement and lifting drive of traditional mechanisms is insufficient. During the punching process, uneven force or movement jamming can easily cause defects such as burrs and breakage in the optical adhesive, making it difficult to meet the processing requirements of high-precision display products. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide an optical adhesive punching mechanism that optimizes the adjustment of the cutter head position, the stability of the lifting drive, and the automatic adjustment of the spacing. This solves the technical problems of low efficiency, poor precision, insufficient adaptability, and unstable punching quality in the existing technology.

[0005] The objective of this utility model is achieved through the following means: An optical adhesive punching mechanism includes: a worktable, with columns mounted on both sides of the upper end of the worktable, a top beam mounted on the upper end of each column, and a linear motion mechanism mounted on one side of the lower end face of the top beam; a hydraulic lifting mechanism is mounted on the lower part of the moving end of the moving mechanism, and a constant pitch mechanism is connected to the lower end face of the hydraulic lifting mechanism; the constant pitch mechanism includes a strip shell, a second drive motor, a second lead screw, a drive block, a linkage block, a fixed block, and a scissor linkage; the second drive motor is fixed inside the strip shell; the second lead screw is mounted on the output end of the second drive motor; the drive block, linkage block, and fixed block are mounted inside the strip shell; the drive block and linkage block are slidably connected to the strip shell; the second lead screw passes through the fixed block, linkage block, and drive block; the drive block is drively connected to the second lead screw; and the scissor linkage is rotatably connected to the drive block, linkage block, and fixed block; a bottom shell is mounted on the bottom of each of the drive block, linkage block, and fixed block; a top block is mounted on the side of the bottom shell opposite to the constant pitch mechanism; and a cutter head is mounted on the lower end of the top block via a support rod. The linear motion mechanism can drive the cutter head to move stably along the top beam, flexibly adjusting the punching position to adapt to the processing requirements of optical adhesives of different sizes; the hydraulic lifting mechanism can provide a stable and controllable lifting driving force to ensure uniform pressure during the punching process and reduce punching defects of optical adhesives; the constant pitch mechanism drives the second lead screw to rotate through the second drive motor, and in conjunction with the linkage of the drive block, linkage block and scissor linkage, realizes the automatic and precise adjustment of the cutter head spacing. It can quickly adapt to a variety of product specifications without manual operation, improving the adaptability and production efficiency of the mechanism, while ensuring the spacing adjustment accuracy to ensure the punching quality.

[0006] Furthermore, the linear motion mechanism includes a first drive motor, a first lead screw, a guide rod, and a slider. The first lead screw is fixed to the output end of the first drive motor, the slider is drivenly connected to the first lead screw, and the slider is slidably connected to the guide rod. The first lead screw is used to control the movement of the slider, thereby driving the hydraulic lifting mechanism to move.

[0007] Furthermore, the first drive motor is connected to the column via a frame, and the guide rod is connected to the column via bolts.

[0008] Furthermore, both sides of the bottom shell are provided with inner cavities. Inside the inner cavity, a pull rod and a wedge-shaped limiting block are installed sequentially from the outside to the inside. A return spring is installed outside the pull rod inside the inner cavity. The return spring enables the wedge-shaped limiting block to automatically reset, thereby automatically engaging with the limiting groove for limiting.

[0009] Furthermore, limiting grooves are provided on both sides of the top block near the wedge-shaped limiting block, and the limiting grooves are adapted to the wedge-shaped limiting block. The wedge-shaped limiting block is forced into the inner cavity when the top block is inserted into the bottom shell through its wedge-shaped inclined surface.

[0010] Furthermore, a base frame is provided at the lower end of the workbench, and the base frame is connected to the workbench by bolts. The base frame is used to support the workbench.

[0011] The beneficial effects of this utility model are: This utility model achieves flexible horizontal movement of the cutter head by setting a linear movement mechanism, which can precisely adjust the working range according to the punching position requirements of the optical adhesive without moving the entire worktable, thus improving the adaptability of the punching position; the hydraulic lifting mechanism provides a stable and controllable downward punching force for the cutter head, avoiding product damage caused by pressure fluctuations during the punching process and ensuring the punching quality. By coordinating the second drive motor, second lead screw, drive block, linkage block, and scissor linkage in the constant pitch mechanism, the automatic and precise adjustment of the cutter head spacing is achieved. The second drive motor drives the second lead screw to rotate, which in turn moves the drive block. The scissor linkage then moves in tandem, causing the linkage block and the fixed block to adjust their positions synchronously. This allows for quick adaptation to the punching requirements of different specifications of optical adhesives without manual operation, solving the problems of low efficiency, poor accuracy, and poor adaptability of traditional manual adjustment mechanisms, and significantly improving production flexibility and processing efficiency.

The drive block 13 and the linkage block 14 are slidably connected to the strip shell 10. The second lead screw 12 passes through the fixed block 15, the linkage block 14, and the drive block 13. The drive block 13 is connected to the second lead screw 12 in a transmission manner. The scissor linkage 16 is rotatably connected to the drive block 13, the linkage block 14, and the fixed block 15. The bottom of the drive block 13, the linkage block 14, and the fixed block 15 are all equipped with a bottom shell 17. A top block 18 is installed on the side of the bottom shell 17 that is away from the equal pitch mechanism. The lower end of the top block 18 is equipped with a cutter head 20 through a support rod 19.

[0015] like Figure 1 and Figure 2 As shown, the linear motion mechanism includes a first drive motor 5, a first lead screw 6, a guide rod 7, and a slider 8. The first lead screw 6 is fixed to the output end of the first drive motor 5. The slider 8 is connected to the first lead screw 6 in a transmission manner and is slidably connected to the guide rod 7. The first drive motor 5 is used to control the rotation of the first lead screw 6, and the first lead screw 6 is used to control the movement of the slider 8, thereby driving the hydraulic lifting mechanism 9 to move.

[0016] like Figure 1 and Figure 2 As shown, the first drive motor 5 is connected to the column 3 through the frame, and the guide rod 7 is connected to the column 3 by bolts.

[0017] like Figure 1 , Figure 3 and Figure 4 As shown, both sides of the bottom shell 17 are provided with inner cavities 22. Inside the inner cavity 22, a pull rod 23 and a wedge-shaped limiting block 25 are installed sequentially from the outside to the inside. A return spring 24 is installed outside the pull rod 23 inside the inner cavity 22. The return spring 24 enables the wedge-shaped limiting block 25 to automatically reset, thereby automatically engaging with the limiting groove 21 for limiting.

[0018] like Figure 1 , Figure 3 and Figure 4As shown, limit grooves 21 are provided on both sides of the top block 18 near the wedge-shaped limit block 25, and the limit grooves 21 are adapted to the wedge-shaped limit block 25.

[0020] The workflow of an optical adhesive punching mechanism in this embodiment is as follows: A linear movement mechanism on one side of the lower end face of the top beam 4 is responsible for adjusting the punching position. Its first drive motor 5 is fixed on the frame of the column 3, driving the first lead screw 6 to rotate, causing the slider 8, which is connected to the first lead screw 6 and sleeved on the guide rod 7, to slide along the guide rod 7, thereby driving the hydraulic lifting mechanism 9 at the lower part of the slider 8 to move to the target position. The hydraulic lifting mechanism 9 drives the equal pitch mechanism connected at the lower end to realize the punching action in the vertical direction. Inside the strip shell 10 of the equal pitch mechanism, the second drive motor 11 drives the second lead screw 12 to rotate, causing the drive block 13, which is connected to the second lead screw 12, to slide inside the strip shell 10. The scissor linkage 16 links the other slidingly connected linkage block 14 and the fixed block 15. The distance between the three can be adjusted to adapt to different punching requirements. The bottom of the drive block 13, linkage block 14 and fixed block 15 are all equipped with a bottom shell 17. The side of the bottom shell 17 away from the equal pitch mechanism is fixed by the wedge-shaped limiting block 25 cooperating with the limiting groove 21 of the top block 18. When the top block 18 is inserted, the wedge-shaped limiting block 25 is forcefully retracted into the inner cavity 22. After insertion, it is reset and locked into the limiting groove 21 under the action of the return spring 24. The lower end of the top block 18 is connected to the cutter head 20 through the support rod 19, so that the cutter head can be easily and quickly disassembled and assembled. Finally, under the drive of the hydraulic lifting mechanism 9, the cutter head 20 completes the punching operation of the optical adhesive.
