[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please refer to Figures 1 to 7 , an embodiment of the present application provides a curved surface film laminating device 100. The curved surface film laminating device 100 includes a substrate 101 and a flipping and pressing mechanism 110 and a product fixing mechanism 140 arranged on the substrate 101, and a nozzle mechanism 130 connected to the flipping and pressing mechanism 110. The flipping and pressing mechanism 110 is used to drive the nozzle mechanism 130 to reciprocate between the film taking position and the film laminating position, and at the same time drive the opening direction of the nozzle mechanism 130 to flip between upward and downward. When the nozzle mechanism 130 is in the film taking position, the opening direction of the nozzle mechanism 130 is upward, and the feeding mechanism supplies the film material 300 to the nozzle mechanism 130. When the nozzle mechanism 130 is in the film laminating position, the opening direction of the nozzle mechanism 130 is downward, and the flipping and pressing mechanism 110 drives the nozzle mechanism 130 to laminat the curved surface of the product 200 on the product fixing mechanism 140.

[0032] The curved surface film laminating device 100 provided in the embodiment of the present application, on the one hand, the flipping and pressing mechanism 110 can drive the suction nozzle mechanism 130 to laminar film at the film taking and laminating position; on the other hand, the suction nozzle mechanism 130 opens upward when taking the film, which is convenient for placing the film material 300 and tearing the film; and opens downward when laminating the film, which is convenient for applying pressure to the product 200 for laminating the film. The flipping and pressing mechanism 110 not only provides the driving force for laminating the film, but also drives the suction nozzle mechanism 130 to flip, thereby realizing the dual-function output of a single driving mechanism, simplifying the structure of the curved surface film laminating device 100, saving costs, and facilitating production operations.

[0033] In a feasible embodiment, the loading mechanism can be a robotic loading mechanism, an assembly line loading mechanism, or manual loading, etc. The loading mechanism is not the inventive point of the present invention and will not be described in detail here. However, it should be noted that the nozzle mechanism 130 of the curved surface film laminating device 100 provided in the embodiment of the present application opens upward when the film is being taken, which is very convenient for taking and placing the film material 300 and facilitating the operation of the loading mechanism.

[0034] Please refer to Figures 1 to 3 ,like Figures 1 to 3As shown, the flipping and pressing mechanism 110 includes: a driving assembly 121, a track plate 111, a gear 112, a rack 113, a rotating shaft 114 and a bearing 115. The track plate 111 is arranged in a vertical direction. The track plate 111 is provided with a through slot along the thickness direction of the track plate 111. The rack 113 is fixed to one side of the track plate 111 along the thickness direction. The gear 112 is gear-engaged with the rack 113. The rotating shaft 114 passes through the through slot. One end of the rotating shaft 114 is connected to the hub of the gear 112. The other end of the rotating shaft 114 is fixedly connected to the nozzle mechanism 130. The bearing 115 is sleeved on the rotating shaft 114 and is arranged on the side of the track plate 111 away from the rack 113 along the thickness direction. The driving assembly 121 and the bearing 115 are arranged on the same side relative to the track plate 111. The fixed end of the driving assembly 121 is fixedly connected to the base plate 101. The output end of the driving assembly 121 is fixedly connected to the bearing 115. The driving assembly 121 drives the bearing 115 to move in a vertical direction and drives the gear 112 to rotate along the rack 113. The rotation of the gear 112 drives the nozzle mechanism 130 to rotate.

[0035] In a feasible implementation, the driving component 121 may be a cylinder.

[0036] In one possible implementation, Figures 1 to 3As shown, a guide wheel 116 is also fixed to one end of the rotating shaft 114 connected to the gear 112. The guide wheel 116 can be fixedly connected to the rotating shaft 114 or the gear 112 through a guide wheel 116 connector 134. In this way, the rotation of the guide wheel 116, the rotating shaft 114, and the gear 112 can be kept consistent. The guide wheel 116 moves in accordance with the inner wall of the through groove away from the rack 113. The through groove includes a first guide groove 1111, a second guide groove 1112, and a third guide groove 1113 connected in the vertical direction. The first guide groove 1111 and the third guide groove 1113 are arranged in the vertical direction, the width of the first guide groove 1111 and the third guide groove 1113 is slightly larger than the diameter of the guide wheel 116, and the second guide groove 1112 is arc-shaped on the side away from the rack 113. When the gear 112 moves in the vertical direction and rotates along the rack 113, the guide wheel 116 moves in contact with the arc-shaped inner wall of the second guide groove 1112. The first guide groove 1111 and the third guide groove 1113 enable the guide wheel 116 to keep the gear 112 from rotating, that is, to keep the rotating shaft 114 from rotating, thereby keeping the nozzle mechanism 130 from rotating. The nozzle mechanism 130 remains vertically upward or vertically downward, thereby ensuring stability when sucking the film material 300 or applying the film to the product 200. At the same time, the first guide groove 1111 and the third guide groove 1113 can also prevent the gear 112 or the rotating shaft 114 from excessively rotating, limiting the movement trajectory of the guide wheel 116. The guide wheel 116 cooperates with the gear 112 and the rack 113 to keep the nozzle mechanism 130 vertically upward or vertically downward, ensuring stability when applying or removing the film.

[0037] Furthermore, the length of the rack 113 is less than or equal to half the circumference of the gear 112. This ensures that the gear 112 can rotate half a circle or less along the rack 113. After rotating half a circle, the guide wheel 116 vertically enters the third guide groove 1113, and the opening of the suction nozzle assembly is vertically downward. Even if the gear 112 rotates less than half a circle along the rack 113, the suction nozzle assembly can still enter the third guide groove 1113 in a vertical position due to the influence of gravity and the movement trajectory of the guide wheel 116 guided by the second guide groove 1112.

[0038] Furthermore, the rack 113 can be arranged in a position such that when the guide wheel 116 disengages from the first guide groove 1111 and enters the second guide groove 1112, the gear 112 contacts the rack 113. In this way, the tooth connection of the gear 112 and the rack 113 drives the rotating shaft 114 to rotate, and cooperates with the guide of the guide wheel 116 moving along the inner wall of the second guide groove 1112, so that the rotation stability of the suction nozzle mechanism 130 is improved, and at the same time, it can ensure that the suction nozzle mechanism 130 keeps the opening upward in the film taking position and keeps the opening downward in the film pasting position.

[0039] In one possible implementation, Figures 1 to 3 As shown, the flip pressing mechanism 110 also includes: a rotating fixed plate 117 and two sliding assemblies 118, the rotating fixed plate 117 is fixedly connected to the bearing 115, the output end of the driving assembly 121 is fixedly connected to the rotating fixed plate 117, and each sliding assembly 118 includes a slider 1181 and a slide rail 1182, the slider 1181 is fixed to the rotating fixed plate 117, and the slide rail 1182 is fixed to the track plate 111 in the vertical direction. In this way, the design of the rotating fixed plate 117 and the sliding assembly 118 can improve the stability of the rotation axis 114 moving in the vertical direction, and improve the overall operation stability of the device. Of course, the sliding assembly 118 does not have to be two, it can also be one or more than two, which will not be repeated here. The two sliding assemblies 118 provided in the embodiment of the present application are symmetrically arranged, which can further improve the stability of the rotation axis 114 moving in the vertical direction, and further improve the overall operation stability of the device.

[0040] In one possible implementation, Figures 1 to 3 As shown, the flip-pressing mechanism 110 also includes a floating joint 119. The floating joint 119 is arranged between the output end of the drive assembly 121 and the rotating fixed plate 117. The main functions of the floating joint 119 include the following: compensating for deviations and adapting to misalignment. Specifically, in actual applications, due to installation errors, thermal expansion, or mechanical movement, there may be a certain degree of eccentricity or misalignment in the connection of components. The floating joint 119 can absorb these deviations through its design characteristics (such as allowing a certain angle of deflection or axial displacement), ensuring that the system can still operate smoothly. Shock absorption and buffering: The floating joint 119 can play a buffering and vibration reduction role, reducing the impact of mechanical vibration on the entire system, improving the dynamic performance of the shaft system, and extending the service life of the equipment. Protecting components: By absorbing irregular loads and impacts, the floating joint 119 can prevent excessive force from being directly transmitted to the shaft, bearings 115, and other sensitive components, thereby reducing wear and damage. High system stability: The floating joint 119 can absorb the eccentric load and lateral load of the piston rod, avoiding problems such as piston rod bending and bearing 115 wear caused by non-parallel installation, ensuring the normal operation of the cylinder and other components.

[0041] In one possible implementation, please refer to Figures 4 to 6 ,like Figures 4 to 6As shown, the suction nozzle mechanism 130 includes: a flexible suction nozzle 131, a contoured pressure head 132 and a mounting shaft 133. The flexible suction nozzle 131 is fixedly connected to the mounting shaft 133. The contoured pressure head 132 is slidably connected to the mounting shaft 133. The interior of the mounting shaft 133 is hollow to form a vacuum pipeline 1331. One end of the mounting shaft 133 is connected to the vacuum connector 138. The other end of the mounting shaft 133 is fixedly connected to the flexible suction nozzle 131. The contoured pressure head 132 has a first passage 1321 in the axial direction, and one end of the first passage 1321 has a larger chamber 1322. The mounting shaft 133 is arranged in the first passage 1321. The end of the mounting shaft 133 connected to the flexible suction nozzle 131 is accommodated in the chamber 1322. The flexible suction nozzle 131 is at least partially accommodated in the chamber 1322. The length of the flexible suction nozzle 131 along the axial direction is less than the depth of the cavity 1322 along the axial direction. The profiling head 132 is slidably connected to the mounting shaft 133. The profiling head 132 is fixedly connected to the rotating shaft 114. When the suction nozzle mechanism 130 is in the film-sticking position, the lower surface of the flexible suction nozzle 131 first contacts the upper surface of the product 200, and the rotating shaft 114 drives the profiling head 132 to move downward in the vertical direction, so that the flexible suction nozzle 131 moves upward relative to the profiling head 132 until the flexible suction nozzle 131 is completely accommodated in the cavity 1322, and the lower surface of the flexible suction nozzle 131 is connected to the profiling inner wall of the profiling head 132 to form a profiling surface that fits the film material 300, and the profiling surface is similar to the curved surface structure of the upper surface of the product 200. Generally, the film material 300 is flat, while the inner wall of the contoured pressure head 132 is curved. Thus, when the flexible suction nozzle 131 protrudes from the contoured pressure head 132, it is easier for the flexible suction nozzle 131 to absorb the film material 300. It should be noted that the above is the relationship between the flexible suction nozzle 131 and the contoured pressure head 132 when the film is applied. Accordingly, it can be understood that when the film is applied, the drive assembly 121 drives the suction nozzle mechanism 130 back to the mold removal position so that the flexible suction nozzle 131 is completely contained within the contoured pressure head 132. In this way, the film material 300 can be placed on the platform on the outer surface of the contoured pressure head 132, which facilitates the removal and placement of the film material 300. For example, the film material 300 can be positioned using the positioning pins 1323 of the contoured pressure head 132. Then, the flexible suction nozzle 131 is extended or protruded from the cavity 1322 of the contoured pressure head 132 to absorb the film material 300 . In this way, both a good position correspondence of the film material 300 and a good absorption effect can be achieved.

[0042] In one possible implementation, Figure 6As shown, the suction nozzle mechanism 130 also includes a connecting member 134 and a spring 135. The connecting member 134 is sleeved on the mounting shaft 133. The connecting member 134 is fixedly connected to the contoured pressure head 132. The connecting member 123 and the contoured pressure head 132 can be fixedly connected by screws or the like. This technology is relatively existing and will not be described here. The connecting member 134 is fixedly connected to the rotating shaft 114. The spring 135 is sleeved on the mounting shaft 133 and is arranged between the connecting member 134 and the flexible suction nozzle 131. When the suction nozzle mechanism 130 is in the film-sticking position, the spring 135 is used to buffer the potential energy of the movement of the flexible suction nozzle 131. In this way, by providing the spring 135, the flexible suction nozzle 131 of the suction nozzle mechanism 130 can be further flexibly contacted with the curved surface of the product 200, reducing the risk of damage to the surface of the product 200.

[0043] In a feasible embodiment, the suction nozzle mechanism 130 further includes a coupling 136 and a fastener 137. The connecting member 134 is sleeved on the mounting shaft 133 through the coupling 136. The fastener 137 can be a screw, which is used to limit the displacement of the connecting member 134 and the contoured pressure head 132 relative to the mounting shaft 133 in the axial direction. Furthermore, the displacement of the connecting member 134 and the contoured pressure head 132 relative to the mounting shaft 133 in another axial direction can be limited by the chamber 1322. In this way, the connecting member 134 and the contoured pressure head 132 are limited at both ends in the axial direction. At the same time, the chamber 1322 can also be stepped (or as Figure 6 The cake shape is described above), so that the large layer of chamber limits the flexible suction nozzle, and the small layer limits the end of the mounting shaft connected to the flexible suction nozzle, which can ensure a good limiting effect, the airtightness of the vacuum passage, and the stability of adsorption.

[0044] In a feasible embodiment, the contoured inner wall of the contoured pressure head 132 is coated with a silicone material. Figure 6 As shown, the contouring head 132 has an annular curved inner wall that contours the curved portion of the product's surface to be applied. The center of the contouring head 132's curved inner wall forms a cavity, while the center portion of the curved surface corresponding to the product is a flat surface, corresponding to the lower surface of the flexible nozzle. When the flexible nozzle is fully accommodated in the cavity, the nozzle's lower surface connects to the upper edge of the annular curved inner wall, forming a continuous surface (possibly with a small gap). This surface, including the contouring curved surface and the nozzle's flat surface, corresponds to the product's surface to be applied.

[0045] In a feasible implementation manner, the material of the flexible suction nozzle 131 is silica gel. The silica gel material has good softness and comfort, enabling it to fit well with the surface of an object during contact. In this way, on the one hand, it can avoid damaging the product 200, and on the other hand, it can better adhere to the product 200 to achieve a better film pasting effect. In addition, the silica gel material has good heat resistance and weather resistance. Silica gel can maintain stable physical properties within a wide temperature range, maintaining its flexibility from low temperature to high temperature, and will not harden or lose elasticity due to environmental temperature changes; silica gel has excellent weather resistance, can resist ultraviolet rays, ozone, and moisture erosion, and is not prone to aging during long-term use, maintaining its performance stability. At the same time, the silica gel material has good insulation performance. Silica gel can effectively prevent electric shock and short circuits, etc., and is safe to use. Moreover, the silica gel material is easy to process and form: silica gel is easy to form through a mold, can produce products 200 with complex shapes, and has good memory. Even after being deformed multiple times, it can restore its original state. Therefore, different flexible suction nozzles 131 can also be designed according to products 200 with different specifications and dimensions. Finally, the silica gel material has good sealing performance. In this way, the flexible suction nozzle 131 can not only ensure the airtightness of the entire vacuum passage but also ensure a good adsorption effect when sucking the negative pressure adsorption film material 300.

[0046] In a feasible implementation manner, as Figure 6 shown, one end of the mounting shaft 133 connected to the flexible suction nozzle 131 has an "I" - shaped structure, and correspondingly, a part of the flexible suction nozzle 131 connected to the mounting shaft 133 is provided with an "丄" - shaped opening. At the same time, the flexible suction nozzle 131 has a plurality of suction nozzle pipelines 1311 penetrating axially. The vacuum pipeline 1331 of the mounting shaft 133 connects the suction nozzle pipelines 1311 with the vacuum joint 138. In this way, the "I" - shaped structure and the "丄" - shaped opening cooperate to not only connect the flexible suction nozzle 131 with the mounting shaft 133 but also ensure the vacuum degree of the vacuum pipeline 1331 of the mounting shaft 133 and the suction nozzle pipelines 1311 of the flexible suction nozzle 131, ensuring the negative pressure effect.

[0047] In a feasible implementation manner, as Figures 4 to 6 shown, the profiling press head 132 is provided with positioning pins 1323 for positioning the film material 300. The profiling press head 132 of the curved surface film pasting device 100 provided by the embodiment of the present application has two positioning pins 1323. Correspondingly, the film material 300 can be provided with pin holes corresponding to the positioning pins 1323. When the feeding mechanism feeds the film material to the suction nozzle mechanism 130, the film material 300 can be fixed by the corresponding positions of the positioning pins 1323 and the pin holes, ensuring the correspondence between the film material 300 and the surface of the product 200 during film pasting.

[0048] In a feasible implementation manner, as Figure 7As shown, the product fixing mechanism 140 includes a storage platform 141 and an adjustment component 142. The storage platform 141 is used to fix the product 200. The adjustment component 142 is used to adjust the horizontal position of the product 200. Furthermore, the adjustment component 142 may include an X-direction adjustment plate 1421 and a Y-direction adjustment plate 1422. The X-direction adjustment plate 1421 and the Y-direction adjustment plate 1422 can be fine-tuned in two directions through a screw structure, thereby achieving fine-tuning of the position of the storage platform 141. In a feasible embodiment, the storage platform 141 may also be provided with a positioning and limiting structure corresponding to the structure of the product 200.
