Description

Technical Field

[0001] This utility model relates to the technical field of film application, and specifically discloses a high-precision and high-efficiency film application fixture. Background Technology

[0002] In the manufacturing processes of hardware, electronics, and plastics products, film application is a common step, primarily used to protect product surfaces from scratches, abrasions, or other physical damage. It can also impart specific aesthetic effects or functional characteristics. The quality and efficiency of the film application process directly impact the product's appearance, lifespan, and production costs. Therefore, developing an efficient, precise, and stable film application technology has always been a key research focus within the industry.

[0003] Existing film application technologies mainly include manual and automated methods. While manual application offers flexibility, it suffers from low efficiency, low precision, and susceptibility to damage, especially in mass production where human error can lead to inconsistent product quality, failing to meet the high precision and efficiency requirements of modern industrial production. Automated film application equipment, while improving efficiency to some extent, is expensive, and its precision and adaptability for complex shapes or small sizes still need improvement. Furthermore, the maintenance costs and operational complexity of automated equipment limit its widespread application in some small and medium-sized enterprises or specific production scenarios. Traditional film application fixtures, while capable of basic application functions, still fall short in efficiency and precision, failing to meet the demands of modern production for high precision, high efficiency, and low labor costs.

[0004] Patent CN209955313U discloses a rapid multi-cavity film-applying fixture, which can perform film-applying operations on multiple workpieces. However, this patent still has some shortcomings in practical applications. The film-applying process relies on manually lifting and separating the film. Since this method separates the film by pinching one end of the film, the force point is concentrated, and it is prone to problems such as film tearing, uneven film application, or damage to the workpiece surface due to human factors, such as improper lifting angle or force, which affects the film-applying efficiency and quality. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-precision and high-efficiency film-applying clamp.

[0006] This utility model discloses a high-precision and high-efficiency film-applying fixture, which adopts the following technical solution: A high-precision and high-efficiency film-applying fixture includes a positioning main base, a marking and positioning block, an adhesive movable block, and a film ejection movable block. The marking and positioning block is equipped with positioning elements for film application and is mounted on the positioning main base. The adhesive movable block and the film ejection movable block are rotatably connected to the positioning main base. The film ejection movable block has several protruding ejection strips spaced apart. The adhesive movable block has several grid grooves for each ejection strip to pass through. The marking and positioning block has several workpiece slots for placing workpieces, with each row of workpiece slots corresponding to one of the grid grooves. The side of the adhesive movable block facing the marking and positioning block is adhesive.

[0007] Preferably, the marking positioning block is placed on the positioning main base, and the positioning main base and the marking positioning block are positioned to each other by positioning components. Preferably, the positioning main base is detachably equipped with a movable block base, and the adhesive movable block and the membrane ejection movable block are hinged to the movable block base and rotate on the positioning main base.

[0008] Preferably, the positioning element is a positioning pin disposed on the positioning main base, and the marking positioning block is provided with a positioning hole that matches and inserts into the positioning pin.

[0009] Preferably, the positioning pin is disposed on the left and right edges of the positioning main base, the positioning hole is disposed vertically, the top of the positioning pin protrudes from the positioning hole, and the adhesive movable block is provided with avoidance grooves on both sides to avoid the positioning pin.

[0010] Preferably, the membrane ejection movable block is provided with an ejection connector, the ejection connector including a limiting block and a plurality of connecting strips connected to the limiting block, the limiting block being located on the side of the adhesive movable block away from the marking positioning block, and the plurality of connecting strips passing through the grid groove and connecting to each of the ejection strips.

[0011] Preferably, the adhesive movable block extends from the hinge end to protrude beyond the positioning main base.

[0012] Preferably, the adhesive movable block is bonded with double-sided adhesive on the side facing the marking positioning block, thus having adhesive properties.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: This invention, through the design of a positioning main base and a marking positioning block working together, as well as the synergistic effect of an adhesive movable block and a film ejection movable block, enables the entire tray of products to be coated with film in one go. This solves the problems of low efficiency and low precision in coating individual products, as well as the easy damage to the appearance. It significantly improves the precision and quality of coating, greatly enhances processing efficiency and product quality, and significantly reduces production costs. In particular, by setting up an adhesive movable block, the film can adhere more tightly to the workpiece surface during the coating process, avoiding problems such as film displacement, wrinkles, or misalignment that may occur during manual operation. It also has the function of separating two layers of film. When separating the protective hard film, the adhesive movable block adheres to the film and rotates to peel it off as a whole. Compared with the traditional method of manually lifting parts, this is more stable and reduces the risk of film tearing or workpiece surface damage caused by hand tremors or improper operation.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figure 1 The double-layer membrane includes a protective hard membrane and several rows and columns of circular marking films attached to the protective hard membrane. (See reference...) Figure 2-6 The high-precision and high-efficiency film-applying fixture of this solution includes a positioning main base 1, a marking and positioning block 2, an adhesive movable block 3, and a film ejection movable block 4. The marking and positioning block 2 is set on the positioning main base 1 and is equipped with a positioning element for the double-layer film 5 to cooperate with. The double-layer film 5 is positioned and placed by the positioning element and the marking and positioning block 2. The adhesive movable block 3 and the film ejection movable block 4 are rotatably connected to the positioning main base 1. The film ejection movable block 4 is provided with several protruding ejection strips 41 at intervals. The adhesive movable block 3 is provided with several grid grooves 31 for each ejection strip 41 to pass through. The marking and positioning block 2 is provided with several workpiece grooves 21 for placing workpieces 6. Each row of workpiece grooves 21 corresponds one-to-one with the grid grooves 31. The side of the adhesive movable block 3 facing the marking and positioning block 2 is adhesive. This solution achieves precise positioning and efficient film application for the workpiece 6 through the cooperation of the positioning main base 1 and the marking positioning block 2, as well as the synergistic effect of the adhesive movable block 3 and the film ejection movable block 4. This effectively improves the accuracy and efficiency of film application, reduces errors from manual operation, and enhances the overall quality of the product. Furthermore, the adhesive movable block 3 can adhere to the protective hard film 52 of the double-layer film 5. When the adhesive movable block 3 is rotated, the protective hard film 52 separates from the marking film 51, completing the film application process. Because the peeling is done by peeling the adhesive surface, the peeling effect is better than the traditional partial peeling method, reducing the risk of film tearing or workpiece surface damage. Subsequently, when the adhesive movable block 3 and the film ejection movable block 4 are lifted and rotated to form an interlocking state, the end of the film ejection movable block 4 can be exposed from the groove 31 of the adhesive movable block 3, thereby peeling off the protective hard film 52 adhered to the adhesive movable block 3. This allows workers to easily remove the protective hard film 52, significantly improving production efficiency.

[0018] As a preferred embodiment, the marking positioning block 2 is placed on the positioning main base 1, and the positioning main base 1 and the marking positioning block 2 are mutually positioned by positioning components. This design allows the marking positioning block 2 to be easily removed and replaced to accommodate workpieces of different shapes or specifications for film application, improving flexibility while ensuring positioning accuracy. Specifically, the positioning component is a positioning pin 11 set on the positioning main base 1, and the marking positioning block 2 has positioning holes 22 that match and engage with the positioning pin 11. The positioning pin 11 is specifically located on the left and right edges of the positioning main base 1, with the positioning holes 22 extending vertically. The top of the positioning pin 11 protrudes from the positioning holes 22. The adhesive movable block 3 has clearance grooves 32 on both sides to avoid the positioning pin 11. Correspondingly, the double-layer film 5 also has holes 521 on both sides corresponding to the positioning pin 11, achieving mutual positioning between the marking film 51 and the workpiece 6. By setting positioning pins 11 on both sides of the positioning main base 1, precise positioning is achieved without significantly affecting the shape design of the double-layer film or the quantity and layout of the marking films. Of course, in other embodiments, the upper and lower surfaces of the marking and positioning block 2 may be provided with positioning pins, and the positioning main base 1 may be replaced with positioning holes, which can also achieve the positioning function. Alternatively, the four corner grooves can also serve the positioning function. However, the structure of this embodiment is simpler and less prone to dust accumulation.

[0019] As a preferred embodiment, a movable block base 12 is detachably mounted on the positioning main base 1. The adhesive movable block 3 and the film ejection movable block 4 are hinged to the movable block base 12 and rotate on the positioning main base 1. By adopting the above design, the adhesive movable block 3 and the film ejection movable block 4 can be disassembled and replaced on the positioning main base 1 to match the film application processing of workpieces 6 of different shapes or sizes, thereby improving the flexibility and versatility of the fixture.

[0020] As a preferred embodiment, the membrane ejection block 4 is equipped with an ejection connector, which includes a limiting block 43 and several connecting strips 42 connected to the limiting block 43. The limiting block 43 is located on the side of the adhesive movable block 3 away from the marking positioning block 2. The several connecting strips 42 pass through the grid groove 31 and are connected to each ejection strip 41. By adopting the above design, the worker can use the limiting block 43 as a handle to press the membrane ejection block 4 down towards the marking positioning block 2, thereby ejecting the protective hard membrane 52 adhered to the adhesive movable block 3. The limiting block 43 serves as both a handle and a force transmission bridge between the various connectors and the ejection strips, improving the uniformity of force on the double-layer membrane when the ejection strips are pressed down. It also restricts the membrane ejection block 4 from crossing the adhesive movable block 3, allowing the worker to work in an orderly manner.

[0021] As a preferred embodiment, the adhesive movable block 3 extends to the side away from the hinge end and protrudes beyond the positioning main base 1, which makes it convenient for the worker to lift the adhesive movable block 3 at this edge and rotate it in the opposite direction to peel off the protective hard film 52.

[0022] As a preferred embodiment, the side of the adhesive movable block 3 facing the marking and positioning block 2 is bonded with double-sided adhesive 33, which makes it sticky. When the stickiness of the double-sided adhesive 33 decreases with the number of uses, it can be peeled off and replaced with new double-sided adhesive 33 for continued use. Of course, in other embodiments, other adhesive application methods can also be used to achieve the stickiness of the adhesive movable block side.

[0023] The high-precision, high-efficiency film-applying fixture of this solution is used as follows: 1) First, place the workpiece 6 to be marked with film into each workpiece slot 21 of the marking positioning block 2; 2) Reference Figure 3 Place the marking and positioning block 2 with the workpiece 6 mounted on the positioning main base 1, and align and insert its positioning hole 22 with the positioning pin 11. 3) Reference Figure 4 Place the marking film 51 of the double-layer film 5 with one side facing down and the protective hard film 52 facing up on the marking positioning block 2, and align the holes 521 on both sides of the double-layer film 5 and insert them into the positioning pin 11 for positioning. At this time, each circular marking film 51 of the double-layer film 5 covers the surface of each workpiece 6. 4) Reference Figure 5 Rotate the adhesive block 3 and the membrane ejection block 4 to the surface of the double-layer membrane 5 and press them down. The ejection strip 41 can pass through the grid groove 31 and contact the surface of the double-layer membrane 5, helping the marking film 51 under the double-layer membrane 5 to adhere more closely to the surface of the workpiece 6. This completes the one-time film application operation for the entire membrane. At this time, the top protective hard film 52 of the double-layer membrane 5 is stuck to the double-sided adhesive 33 on the bottom surface of the adhesive block 3. 5) Reference Figure 6 The adhesive movable block 3 and the film ejection movable block 4 are rotated in the opposite direction and lifted up. At this time, the marking film 51 is transferred to the surface of the workpiece 6, while the protective hard film 52 is separated from the marking film 51 along with the adhesive movable block 3. 6) Reference Figure 6 When the membrane ejection block 4 and the bonding block 3 are rotated in opposite directions and interlocked, the ejection strip 41 of the membrane ejection block 4 is ejected from the grid groove 31 of the bonding block 3, thereby peeling off the protective hard film 52 that is attached to the surface of the bonding block 3, so that the worker can remove the protective hard film 52.
