Description

Technical Field

[0001] This utility model relates to the field of optical adhesive packaging technology, specifically to a convenient packaging machine for optical compensation adhesive. Background Technology

[0002] Optical compensation adhesive is a key material used in display assembly. It is widely used in the full lamination process between touch screens and cover glass, OLED modules and protective glass, etc. It has the characteristics of high light transmittance, low haze, excellent adhesion strength and low curing shrinkage. It can effectively eliminate the air layer between layers and improve the optical performance and mechanical stability of display devices. Because optical compensation adhesive has extremely high requirements for cleanliness, air bubble content and dispensing accuracy, its packaging process must be completed in a dust-free environment by special equipment to ensure the quality of subsequent lamination processes. The dispensing equipment typically consists of a storage tank, a precision metering pump, a dispensing valve, a control system, and a worktable for carrying and positioning the dispensing bottles. First, the operator places the empty dispensing bottle in the positioning fixture on the worktable. The equipment draws a fixed amount of adhesive from the storage tank through the metering pump and injects the adhesive precisely into the dispensing bottle through the dispensing valve and needle. After the injection is completed, the equipment issues a prompt, and the operator removes the full bottle and replaces it with a new empty bottle, thus completing one dispensing cycle. However, the dispensing bottles inside the portable dispensing machine do not have a self-sealing structure, which means that they need to be manually sealed after the injection is completed. This manual step not only reduces the overall dispensing efficiency and extends the production cycle, but also easily introduces the risk of contamination during operation, reducing the flexibility of the portable dispensing machine. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a convenient dispensing machine for optical compensation adhesive, which can effectively solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a convenient dispensing machine for optical compensation adhesive, including a portable dispensing machine body. A feeding pipe is located above the portable dispensing machine body. A movable block is slidably connected to the front of the portable dispensing machine body. A feeding port is fixedly connected below the movable block. A clamp is connected above the portable dispensing machine body. The clamp has a sealing structure inside. A collection bucket is clamped inside the clamp. A limiting structure is located above the collection bucket. A column is connected outside the feeding port. A guide groove is opened outside the column. A circular groove is opened inside the clamp. The sealing structure includes a collar, an L-shaped plate, a spur gear, and a sealing plate. A large gear is rotatably connected inside the collar. An internal rack is provided inside the large gear. A half gear is connected outside the sealing plate. A limiting rod is provided inside the spur gear.

[0005] Furthermore, the portable dispensing machine is equipped with a control panel, and a flexible hose is connected to the top of the conveying pipe, which is connected to the feeding port through the flexible hose.

[0006] Furthermore, the collar is fixedly connected above the collection bucket, the sealing plate is rotatably connected inside the collar, and the L-shaped plate is fixedly connected above the collar.

[0007] Furthermore, the spur gear is rotatably connected inside the L-shaped plate, the spur gear meshes with the large gear, and the internal rack meshes with the half gear.

[0008] Furthermore, the limiting structure includes an arc-shaped plate and a positioning plate. The positioning plate is fixedly connected to the outside of the collection bucket, the arc-shaped plate is slidably connected to the circular groove, and a push rod is fixedly connected to one side of the arc-shaped plate.

[0009] Furthermore, the arc-shaped plate is snapped into the positioning plate, the positioning plate is snapped into the fixture, the positioning plate is provided with bolts, and the positioning plate is connected to the arc-shaped plate by the bolts.

[0010] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. By setting up columns, guide grooves, sealing structures, and collection buckets, when the moving block moves, the guide groove on the surface of the column will contact the limiting rod, and then the limiting rod will drive the spur gear to rotate. Since the large gear meshes with the spur gear, and the internal rack inside the large gear meshes with the half gear, multiple sealing plates inside the collar will unfold synchronously. When multiple sealing plates are fully unfolded, the feeding port will penetrate the collar, and then the optical compensation adhesive inside will be transported to the fixture through the feeding pipe and hose. When the feeding port is disengaged from the collar, multiple sealing plates will perform sealing treatment. This portable dispensing machine enables multiple sealing plates to rotate synchronously through the cooperation between the spur gear, the large gear, and the half gear. It not only realizes the automatic alignment and sealing between the feeding port and the collection bucket, but also significantly improves the automation level of the dispensing process, reduces manual intervention, and avoids problems such as contamination or poor sealing caused by manual operation. It is especially suitable for optical adhesive dispensing environments with extremely high cleanliness requirements.

[0011] 2. By setting a limiting structure, the collection bucket is clamped into the fixture by the positioning plate. The push rod drives the arc plate to slide in the circular groove. When the arc plate slides, it will be clamped into the positioning plate. Subsequently, the positioning plate is locked to the arc plate by bolts. This not only improves the clamping accuracy and repeatability, but also facilitates the quick replacement of the collection bucket, shortens the production interval, further improves the overall dispensing efficiency, and ensures that the column can be accurately inserted into the sealing plate when it moves.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the embodiments. Example

[0017] Reference Figure 1-4This is the first embodiment of the present invention, which discloses a portable dispensing machine for optical compensation adhesive. It includes a portable dispensing machine body 1, a feeding pipe 4 on the top of the body 1, a movable block 2 slidably connected to the front of the body 1, a feeding port 6 fixedly connected to the bottom of the movable block 2, a clamp 3 connected to the top of the body 1, a sealing structure 7 inside the clamp 3, a collection bucket 11 clamped inside the clamp 3, a limiting structure 8 above the collection bucket 11, a column 10 connected to the outside of the feeding port 6, a guide groove 12 on the outside of the column 10, a circular groove 13 inside the clamp 3, and a sealing structure 7 including a collar 701, an L-shaped plate 702, a spur gear 703, and a sealing plate 705. A large gear 707 is rotatably connected inside the collar 701, an internal rack 708 is inside the large gear 707, a half gear 706 is connected to the outside of the sealing plate 705, and a limiting rod 704 is inside the spur gear 703.

[0018] The portable dispensing machine body 1 is equipped with a control panel 9. The top of the conveying pipe 4 is connected to a flexible hose 5. The conveying pipe 4 is connected to the feeding port 6 through the flexible hose 5. The collar 701 is fixedly connected above the collection bucket 11. The sealing plate 705 is rotatably connected inside the collar 701. The L-shaped plate 702 is fixedly connected above the collar 701. The spur gear 703 is rotatably connected inside the L-shaped plate 702. The spur gear 703 meshes with the large gear 707. The internal rack 708 meshes with the half gear 706.

[0019] By setting up a connection structure between the control panel 9, hose 5, conveying pipe 4 and feeding port 6, and a sealing transmission system composed of collar 701, L-shaped plate 702, spur gear 703, sealing plate 705, etc., the automatic conveying of optical compensation adhesive and the synchronous opening and sealing function of collection tank 11 are realized. The control panel 9 can accurately control the stroke and pause time of the moving block 2, while the hose 5 provides the necessary flexible connection to adapt to the movement requirements of the feeding port 6, ensuring that the adhesive is dispensed under conditions of no pollution and no leakage, which significantly improves the intelligence level and ease of operation of the equipment. Example

[0020] Reference Figure 4 This is the second embodiment of the present invention, which differs from the first embodiment in that: The limiting structure 8 includes an arc-shaped plate 801 and a positioning plate 802. The positioning plate 802 is fixedly connected to the outside of the collection bucket 11, and the arc-shaped plate 801 is slidably connected to the circular groove 13. A push rod 803 is fixedly connected to one side of the arc-shaped plate 801. The arc-shaped plate 801 is snapped into the positioning plate 802, and the positioning plate 802 is snapped into the clamp 3. A bolt 804 is provided in the positioning plate 802, and the positioning plate 802 is connected to the arc-shaped plate 801 through the bolt 804.

[0021] By setting up a limiting structure 8 consisting of an arc plate 801, a positioning plate 802, a push rod 803, and a bolt 804, the collection bucket 11 is quickly and accurately positioned and reliably fixed. The sliding fit between the arc plate 801 and the circular groove 13 provides a preliminary centering function, the push rod 803 facilitates manual operation, and the bolt 804 provides the final mechanical locking force, ensuring that the collection bucket 11 does not shift during the dispensing process, thus improving the efficiency and safety of the equipment.

[0022] The remaining structure is the same as that in Example 1.

[0023] The workflow of this utility model is as follows: When the portable dispensing machine is encapsulating optical compensation adhesive, the collection bucket 11 can be clamped into the fixture 3 by the positioning plate 802, and the arc plate 801 can be slid in the circular groove 13 by the push rod 803. When the arc plate 801 slides, it will be clamped into the positioning plate 802. Subsequently, the positioning plate 802 locks the arc plate 801 with bolts 804. Then, the portable dispensing machine body 1 drives the moving block 2 to move vertically through the control screen 9. When the moving block 2 moves, the guide groove 12 on the surface of the column 10 will contact the limit rod 704. Then the limit rod 704 will drive the spur gear 703 to rotate. Since the large gear 707 meshes with the spur gear 703, and the internal rack 708 in the large gear 707 meshes with the half gear 706, the multiple sealing plates 705 in the collar 701 will unfold synchronously. When the multiple sealing plates 705 are fully unfolded, the feeding port 6 will penetrate the collar 701. Subsequently, the optical compensation adhesive inside will be transported to the fixture 3 through the feeding pipe 4 and the hose 5. When the feeding port 6 is disengaged from the collar 701, the multiple sealing plates 705 will perform sealing treatment.

[0024] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
