[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] When bonding the film to the glass, a bonding fixture is first used to initially bond the film to the glass to facilitate subsequent formal bonding. Existing bonding fixtures cannot press the film onto the glass with a fixed pressure, which can lead to problems such as poor bonding, localized edge lifting, and wrinkles in the film.

[0035] Therefore, such as Figures 1-3 As shown, this embodiment provides a bonding fixture, which includes a cover plate assembly 1, a base assembly 2, and a handle assembly 3. The cover plate assembly 1 has an adsorption part 11 for adsorbing the auxiliary film. The base assembly 2 has a receiving groove 211 in which the film to be bonded is received. The cover plate assembly 1 covers the base assembly 2, and the auxiliary film is bonded to the film to be bonded. The handle assembly 3 includes two handles 31, which are rotatably disposed on opposite sides of the base assembly 2. The handles 31 can rotate to switch between a locked state and an unlocked state. In the locked state, the handles 31 can press against the cover plate assembly 1 to press the cover plate assembly 1 tightly against the base assembly 2.

[0036] Place the part to be coated into the receiving groove 211 of the base assembly 2, and adsorb the auxiliary film onto the adsorption part 11 of the cover assembly 1. Place the cover assembly 1 on the base assembly 2 so that the auxiliary film and the part to be coated are initially bonded. Then rotate the handles 31 on both sides to the locked state. At this time, the handles 31 press against the cover assembly 1 to press the cover assembly 1 tightly onto the base assembly 2, forming a stable pressing force. The stable pressing force is transmitted through the cover assembly 1 to the contact surface between the auxiliary film and the part to be coated, completing the stable bonding. After holding the pressure for a certain time, rotate the handles 31 on both sides to the unlocked state, and then remove the cover assembly 1. The bonded auxiliary film and the part to be coated can then be taken out.

[0037] The bonding fixture provided in this embodiment uses an adsorption part 11 to adsorb and fix the auxiliary film, which will not damage the auxiliary film and can prevent the auxiliary film from shifting or wrinkling before bonding. The receiving groove 211 allows the film to be bonded to be accurately placed on the base assembly 2, ensuring that the auxiliary film can be accurately aligned with the film to be bonded when the cover plate assembly 1 is placed on the base assembly 2, avoiding errors caused by manual adjustment. The handles 31 on both sides of the base assembly 2 can stably press the cover plate assembly 1 onto the base assembly 2, with stable and evenly distributed pressing force, significantly reducing the bonding failure rate. Turning the handles 31 can quickly lock or unlock, which is highly efficient. Compared with manual pressing, the pressure of pressing the cover plate assembly 1 onto the base assembly 2 using the handles 31 is controllable and highly repeatable, making it suitable for mass production.

[0038] In this embodiment, the component to be coated is glass.

[0039] Optionally, such as Figure 2 As shown, the cover plate assembly 1 includes a cover plate body 12 and an adsorption part 11, which is detachably connected to the cover plate body 12. Different auxiliary films have different adsorption requirements. The detachable design allows for quick replacement of the appropriate adsorption part 11, improving the adaptability of this bonding fixture. When either the adsorption part 11 or the cover plate body 12 is damaged, it can be replaced individually without replacing the entire cover plate assembly 1, significantly reducing maintenance costs.

[0040] Specifically, the adsorption part 11 can be detachably connected to the cover plate body 12 by common connection methods such as buckles, magnetic attraction or screws. The specific connection method is not limited in this embodiment.

[0041] Optionally, such as Figure 3As shown, the base assembly 2 includes a base body 22 and a mounting part 21. The mounting part 21 is detachably connected to the cover plate body 12, and a receiving groove 211 is formed on the mounting part 21. By replacing different mounting parts 21, the base assembly 2 can adapt to film parts of different shapes, improving the versatility of this bonding fixture. When either the mounting part 21 or the base body 22 is damaged, it can be replaced separately without replacing the entire base assembly 2, significantly reducing maintenance costs.

[0042] Specifically, the mounting part 21 can be detachably connected to the base body 22 by common connection methods such as snaps, magnetic attraction or screws. The specific connection method is not limited in this embodiment.

[0043] Optionally, such as Figure 1 , Figure 3 As shown, the handle 31 is rotatably connected to the base assembly 2 at both ends. A plurality of elastic elements 32 are provided on one side of the handle 31. In the locked state, the elastic elements 32 press against the cover plate assembly 1 to press the cover plate assembly 1 tightly against the base assembly 2. The handle 31 is stably and rotatably connected to the base assembly 2. When the handle 31 is rotated to the locked state, that is, when the handle 31 is rotated perpendicular to the cover plate assembly 1 and the base assembly 2, the elastic elements 32 on the side of the handle 31 facing the cover plate assembly 1 are compressed. Energy is stored through elastic deformation, and the reaction force is evenly transmitted to the cover plate assembly 1 to stably press the cover plate assembly 1 against the base assembly 2. Several elastic elements 32 disperse the pressing force to the surface of the cover plate, avoiding excessive or insufficient local pressure and reducing the failure rate of bonding; the buffering effect of the elastic elements 32 can absorb the impact force during operation, prevent the handle 31 from having excessive friction with the cover plate assembly 1 during rotation, prevent the handle 31 or the cover plate assembly 1 from being scratched, and extend the service life of the handle 31 and the cover plate assembly 1; turning the handle 31 can complete the locking, with short operation time and significantly improved production cycle.

[0044] Specifically, such as Figure 3 As shown, the handle 31 includes a body part 311 and two fixing parts 312. The two fixing parts 312 are vertically disposed at both ends of the body part 311. The fixing parts 312 are rotatably connected to the base assembly 2 through a rotating shaft, so as to realize the rotatable connection of the handle 31 to the base assembly 2.

[0045] Optionally, the handle 31 has several guide grooves along its length. In the locked state, the extension direction of the guide grooves is perpendicular to the cover plate assembly 1, and each guide groove accommodates an elastic element 32. The extension direction of the guide grooves is perpendicular to the cover plate in the locked state, so that in the locked state, the elastic element 32 can only be compressed in a direction perpendicular to the cover plate, avoiding non-perpendicular pressure caused by bending or lateral displacement of the elastic element 32, ensuring that the pressing force is always perpendicular to the auxiliary film and the film to be applied, and preventing the auxiliary film from shifting, curling, or wrinkling due to oblique force.

[0046] Optionally, the elastic element 32 is a spring plunger. One end of the spring plunger is connected to the bottom of the guide groove so that the elastic plunger is stably disposed in the guide groove. It should be noted that the connection method can be any method commonly used in the prior art, and this embodiment does not limit it.

[0047] Optionally, such as Figure 1 , Figure 2 As shown, the cover plate assembly 1 also includes several air pipe connectors 13. The adsorption part 11 has a cavity, and several adsorption holes 111 are formed on the surface of the adsorption part 11, which communicate with the cavity. The air pipe connectors 13 are connected to the adsorption part 11 and communicate with the cavity. The adsorption part 11 has a cavity inside, and several adsorption holes 111 are formed on its surface. The cavity communicates with the air pipe connectors 13, which can be connected to a vacuum pump. After the vacuum pump is started, the air in the cavity is extracted to form a negative pressure environment. The external atmospheric pressure presses the excipient film tightly onto the surface of the adsorption part 11 through the adsorption holes 111. In this embodiment, the adsorption holes 111 are arranged in a matrix in the adsorption part 11 to ensure that the excipient film is subjected to uniform force and to avoid local deformation or damage caused by single-point adsorption.

[0048] Optionally, such as Figure 2 As shown, the auxiliary film has several first positioning holes, and the adsorption part 11 is provided with several first positioning elements 112 protruding from it. The several first positioning elements 112 are arranged in a one-to-one correspondence with the several first positioning holes. The several first positioning holes on the auxiliary film are arranged in a corresponding manner with the several first positioning elements 112 on the adsorption part 11. When the auxiliary film is adsorbed onto the adsorption part 11, the several first positioning elements 112 pass through the several first positioning holes to accurately position the auxiliary film, ensuring that when the cover plate assembly 1 is placed on the base assembly 2, the auxiliary film can be aligned with the film to be applied.

[0049] In this embodiment, there are two first positioning elements 112, which are positioning pins or positioning posts.

[0050] Optionally, such as Figure 2 , Figure 3As shown, the cover plate assembly 1 has a plurality of protruding second positioning elements 14, and the base assembly 2 has a plurality of recessed second positioning holes 23, with the plurality of second positioning elements 14 corresponding to the plurality of second positioning holes 23. When the cover plate assembly 1 needs to be placed on the base assembly 2, the plurality of second positioning elements 14 can be inserted into the plurality of second positioning holes 23, resulting in quick and accurate positioning without the need for multiple adjustments.

[0051] In this embodiment, there are four second positioning elements 14, which are positioning pins or positioning posts.

[0052] Optionally, such as Figure 3 As shown, the bonding fixture also includes several limiting components 4. Each limiting component 4 includes two limiting blocks 41, which are slidably disposed on opposite sides of the receiving groove 211. The limiting blocks 41 abut against the side wall of the film to be bonded. The two limiting blocks 41 are respectively disposed on opposite sides of the receiving groove 211. By sliding and adjusting the distance, they form a physical constraint with the side wall of the film to be bonded. After the film to be bonded is placed in the receiving groove 211, the sliding limiting blocks 41 clamp the film to be bonded from both sides and fix the limiting blocks 41 to ensure that the film to be bonded will not shift during the bonding process.

[0053] Specifically, the positioning part has an installation groove, which is connected to the receiving groove 211, and the limiting block 41 is slidably disposed in the installation groove.

[0054] In this embodiment, there are three sets of limiting components 4. Two sets of limiting components 4 are distributed along the length of the receiving groove 211, and one set of limiting components 4 is distributed along the width of the receiving groove 211.

[0055] Optionally, the limiting component 4 also includes a locking member. One of the base component 2 and the limiting block 41 has an oblong hole 411, and the other has a fixing hole. The extending direction of the oblong hole 411 is perpendicular to the side wall of the film to be applied. The locking member passes through the oblong hole 411 and the fixing hole to fix the limiting block 41 to the base component 2. The oblong hole 411 in one of the limiting block 41 and the base component 2, with its extending direction perpendicular to the side wall of the film to be applied, allows the limiting block 41 to slide within the adjustment range of the oblong hole 411 to limit and fix the film to be applied. The locking member passes through the oblong hole 411 and the fixing hole to achieve precise fixation of the limiting block 41. The locking member can be a screw or a quick-release pin.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
