Description

Technical Field

[0001] This utility model relates to the field of film-applying fixture technology, and in particular to a film-applying fixture for the inside of a product. Background Technology

[0002] Currently, for products where manual film application is not feasible, manual application using tweezers and the aid of the eyes and hands is generally required. This process is extremely inefficient, and due to the lack of a positioning device, the accuracy is very poor, resulting in a high rework rate and making mass production impossible. While it is possible to invest significant manpower and resources to develop fully automated equipment for this purpose, supplemented by CCD for precise positioning, the high cost makes it difficult to sustain when order volumes are small.

[0003] To address the aforementioned issues, this utility model document proposes a fixture for applying a film inside a product. Utility Model Content

[0004] This utility model provides a fixture for applying film inside a product, which solves the problem of existing technologies where film cannot be manually applied to products. Currently, it is generally necessary to manually apply the film with tweezers, relying on the human eye and hand. This is extremely inefficient, and because there is no positioning device to assist, the accuracy is very poor, the rework rate is also very high, and it is not suitable for mass production. Although it is possible to invest a lot of manpower and financial resources to develop fully automated equipment for operation, supplemented by CCD for precise positioning, the cost is very high when the order volume is small, and it is often difficult to maintain.

[0005] This utility model provides the following technical solution:

[0006] A fixture for applying a film inside a product, comprising:

[0007] The base has a wedge-shaped push rod structure fixedly installed on one side of the vertical plate. A product anti-deformation positioning mechanism is inserted into the wedge-shaped push rod structure. An injection molded part that needs to be internally coated is inserted into and fixed to the product anti-deformation positioning mechanism. The product anti-deformation positioning mechanism is provided with a protective film positioning hole that is aligned with the area inside the injection molded part that needs to be coated. A film-coating push plate structure is longitudinally slidably installed in the protective film positioning hole. A protective film body is provided on the upper surface of the film-coating push plate structure.

[0008] In one possible design, four guide posts are fixedly arranged in a rectangular array on one side of the base vertical plate, with a wedge-shaped push rod structure as the center, and the side plate of the product anti-deformation positioning mechanism is provided with guide sleeve holes for the corresponding guide posts to pass through.

[0009] In one possible design, a spring is fitted onto the guide post.

[0010] In one possible design, the film-applying push plate structure is a wedge-shaped block used in conjunction with a wedge-shaped push rod structure.

[0011] In one possible design, one side of the protective film body is adhesive.

[0012] In one possible design, the film-applying pusher structure includes a silicone base film.

[0013] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0014] The working principle and usage process of this technical solution are as follows:

[0015] When using it, the operator first takes out a protective film body from the storage area, with the adhesive side of the protective film body facing up, and carefully places it into the protective film positioning hole on the product anti-deformation positioning mechanism. Ensure that the protective film body is accurately placed on the upper surface of the film-applying push plate structure, and is centered without any skewing. Then, pick up the injection molded part that needs to be internally filmed, align its cavity with the product anti-deformation positioning mechanism, and slowly and steadily insert the injection molded part into the product anti-deformation positioning mechanism until the injection molded part is completely positioned. At this time, the area inside the injection molded part that needs to be filmed is aligned with the protective film positioning hole.

[0016] In the initial state, due to the spring force, the product anti-deformation positioning mechanism is in the initial position close to the operator. The wedge-shaped push rod structure is in a relatively open state, and the film-applying push plate structure is located at the bottom of the protective film positioning hole. The protective film body has not yet contacted the injection molded part. The operator holds the product anti-deformation positioning mechanism in the appropriate position with both hands and applies appropriate pushing force to move the product anti-deformation positioning mechanism. During the movement, the product anti-deformation positioning mechanism compresses the spring, and at the same time, the wedge-shaped push rod structure gradually enters the interior of the product anti-deformation positioning mechanism. As the product anti-deformation positioning mechanism continues to move, the inclined surface at the front end of the wedge-shaped push rod structure gradually contacts the film-applying push plate. At the sloping position below the structure, the operator continuously applies a pushing force, and the wedge-shaped pusher structure further squeezes the sloping surface below the film-applying pusher structure. Due to the interaction between the two sloping surfaces, the film-applying pusher structure is subjected to an upward component force, thus beginning to rise longitudinally along the protective film positioning hole. During the lifting process, the protective film body on its upper surface moves upward and gradually approaches the area inside the injection molded part that needs to be film-applied. When the film-applying pusher structure is raised to a certain height, the adhesive surface of the protective film body contacts the area inside the injection molded part that needs to be film-applied, and under the elastic action of the silicone base film, the protective film body is evenly and smoothly pasted inside the injection molded part, while air is effectively expelled.

[0017] After the film application is completed, the operator releases their hands and stops applying pressure. At this time, under the elastic force of the spring, the product anti-deformation positioning mechanism gradually returns to its initial position. At the same time, the film application push plate structure, due to the loss of the squeezing of the wedge-shaped push rod structure, also moves downward along the positioning hole of the protective film and returns to its initial position. Finally, the operator removes the injection molded part with the film applied from the product anti-deformation positioning mechanism and places it in the designated position, completing the entire film application process.

[0018] This utility model has the following beneficial effects:

[0019] This invention replaces manual positioning and application of film, solving the problem of extremely low efficiency in manual film application. It also improves application accuracy, reduces rework rate, and ensures mass production. Compared with investing a lot of manpower and financial resources in developing fully automated equipment, this fixture has a simple design, reduces processing difficulty and cost, and has a greater cost advantage when order volume is small.

[0020] This utility model has no pneumatic or electrical components; it cleverly utilizes mechanical structures to complete the operation. It features a spring structure and a wedge-shaped pusher mechanism that converts forward and backward thrust into up and down thrust. No other external power design is required, enabling automatic opening and closing. Subsequent operation and maintenance are easier, and the requirements for operators are lower, allowing even novice employees to operate quickly and accurately.

[0021] This utility model is a systematic design for internal film application in products. It breaks down the process into a series of small, sequential actions and strengthens the design to ensure the cumulative accuracy of film application. Furthermore, the alignment mechanism does not require additional mechanisms and is derived from the necessary actions. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] Example 1

[0031] Please refer to Figure 1-4 A film application fixture, comprising:

[0032] The base 1 provides a stable support foundation for the entire film application fixture. A vertical plate is provided on the base 1, and an installation space is reserved on one side of the vertical plate for fixing other key components. The wedge-shaped push rod structure 2 is firmly installed on one side of the vertical plate of the base 1 by bolts, welding or other reliable fixing methods. The front end of the structure has a bevel with a specific angle. This bevel design is the key part to realize the conversion of horizontal thrust to vertical thrust. Its bevel angle and length are precisely calculated to ensure that the film application push plate structure 8 can be lifted according to the expected trajectory.

[0033] The product anti-deformation positioning mechanism 3 is shaped like a plug rod, with one end having a plug-in cavity that matches the wedge-shaped push rod structure 2. It connects to the wedge-shaped push rod structure 2 via a plug-in connection and can slide along the wedge-shaped push rod structure 2. The external shape of the product anti-deformation positioning mechanism 3 is precisely designed according to the internal cavity of the injection molded part 10 that needs to be internally film-coated, enabling precise positioning of the injection molded part 10 and preventing it from shaking or shifting during the film-coating process. On the side plate of the product anti-deformation positioning mechanism 3, corresponding to the guide post 4 on the vertical plate of the base 1, there is a guide sleeve hole 6. Linear bearings and other components are installed in the guide sleeve hole 6 to reduce friction between the guide post 4 and the guide sleeve hole 6, making the sliding of the product anti-deformation positioning mechanism 3 smoother.

[0034] On one side of the vertical plate of the base 1, four guide posts 4 are arranged in a rectangular array with the wedge-shaped push rod structure 2 as the center, and are fixed by welding or threaded connection. Each guide post 4 is fitted with a spring 5. One end of the spring 5 is in close contact with the vertical plate of the base 1, and the other end is in contact with the side plate of the product anti-deformation positioning mechanism 3. The elasticity of the spring 5 can provide sufficient reset power while ensuring the stability of the product anti-deformation positioning mechanism 3 during the sliding process.

[0035] The product anti-deformation positioning mechanism 3 is provided with a protective film positioning hole 7. The size and shape of the protective film positioning hole 7 match the protective film body 9 and are used to position the protective film body 9. The film-applying push plate structure 8 is longitudinally slidably set in the protective film positioning hole 7. Its shape is a wedge block that works with the wedge-shaped push rod structure 2. The lower surface of the film-applying push plate structure 8 has an inclined surface that matches the inclined surface of the wedge-shaped push rod structure 2. When the wedge-shaped push rod structure 2 moves, the two inclined surfaces press against each other, thereby lifting the film-applying push plate structure 8. The upper surface of the film-applying push plate structure 8 is flat and is used to place the protective film body 9.

[0036] The injection molded part 10 is a product that requires internal film application. Its inner cavity is adapted to the external shape of the product anti-deformation positioning mechanism 3 and can be accurately inserted into the product anti-deformation positioning mechanism 3. One side of the protective film body 9 is adhesive and the other side is a smooth surface, which is used to contact the film application push plate structure 8. The size and shape of the protective film body 9 are customized according to the size and shape of the area inside the injection molded part 10 that needs to be filmed, so as to ensure that the film application area can be completely covered.

[0037] This application can be used for applying films inside products, or in other fields applicable to this application.

[0038] Example 2

[0039] Improvements based on Example 1:

[0040] A film-applying fixture for internal product application, which is used in the field of film-applying fixtures;

[0041] Please refer to Figure 3 On the upper surface of the film-applying push plate structure 8, there is also a layer of silicone base film. The silicone base film is firmly fixed to the film-applying push plate structure 8 by glue or other adhesive methods. The silicone base film has good elasticity and flexibility, which can play a role in buffering and uniform pressure during the film application process, ensuring that the protective film body 9 can be tightly and flatly pasted into the area inside the injection molding 10 where the film needs to be applied, while effectively eliminating air and avoiding the generation of air bubbles.

[0042] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
