The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0029] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

For example, if the angle between two directions is 88°-95°, the two directions can be considered perpendicular; if the angle between two directions is 0°-10°, the two directions can be considered parallel.

[0031] This application provides a film-applying device, which is used to apply films to various products such as packaging boxes, cardboard, displays, metal plates, or electronic components.

[0032] The film application device according to an embodiment of this application is described below with reference to the accompanying drawings.

[0033] Reference Figures 1 to 5 The film-applying device 1 provided in this application embodiment includes a feeding device 10, at least two film separation devices 20, and at least two film-applying devices 30. The feeding device 10 is used to provide the product 2 to be film-applied. The at least two film separation devices 20 are respectively disposed on both sides of the feeding device 10 along the first direction X, and the film separation devices 20 are configured to separate the film 3 from the material belt 4. The film-applying devices 30 are disposed in a one-to-one correspondence with the film separation devices 20. The film-applying device 30 includes an adsorption mechanism 31 and a film-applying driving mechanism 32. The adsorption mechanism 31 is configured to adsorb or release the film 3 separated by a corresponding film separation device 20. At least a portion of the film-applying driving mechanism 32 is disposed on one side of the feeding device 10 along the second direction Y. The film-applying driving mechanism 32 is connected to the adsorption mechanism 31 and is configured to drive the adsorption mechanism 31 to move along the first direction X and the third direction Z, where the first direction X, the second direction Y, and the third direction Z intersect each other.

[0034] Optionally, the first direction X, the second direction Y, and the third direction Z are all perpendicular to each other. The third direction Z is parallel to the direction of gravity, and both the first direction X and the second direction Y are parallel to the horizontal direction.

[0035] The material strip 4 includes a base film 5 and a film sheet 3 attached to the base film 5. The film sheet separation device 20 can separate the film sheet 3 from the base film 5 so that the film application device 30 can apply the film sheet 3 to the product 2. The film sheet 3 can be a blue film or other film structures.

[0036] Optionally, the adsorption mechanism 31 includes a flexible suction plate for adsorbing the membrane 3 to reduce the risk of damage to the membrane 3.

[0037] The film-applying driving mechanism 32 drives the adsorption mechanism 31 to move along the third direction Z, which facilitates the actions of picking up the film 3 and attaching the film 3 to the product 2. The film-applying driving mechanism 32 drives the adsorption mechanism 31 to move along the first direction X, so that the adsorption mechanism 31 moves back and forth between the feeding device 10 and the film separation device 20, which is beneficial for batch products to be film-applied and improves the film-applying efficiency.

[0038] At least two film separation devices 20 are distributed on both sides of the feeding device 10 along the first direction X, with at least one film separation device 20 provided on each side of the feeding device 10 along the first direction X. Each film separation device 20 is close to the feeding device 10, which facilitates the transfer and attachment of the film 3 separated by the corresponding film separation device 20 to the product 2 of the feeding device 10 by each film application device 30. This helps to shorten the transfer path of the film 3 by the film application device 30 and improve the film application efficiency.

[0039] The number of film-applying devices 30 and film-separating devices 20 is the same. The film-applying drive mechanisms 32 of at least two film-applying devices 30 can be located on the same side of the feeding device 10 along the second direction Y, or they can be distributed on both sides of the feeding device 10 along the second direction Y.

[0040] In some examples, refer to Figure 1 There are two film separation devices 20 and two film application devices 30. The two film separation devices 20 are respectively arranged on both sides of the feeding device 10 along the first direction X, and the two film application devices 30 are arranged along the first direction X, close to the two film separation devices 20, which helps to shorten the transfer path of each film application drive mechanism 32. The film application drive mechanisms 32 of the two film application devices 30 are at least partially located on the same side of the feeding device 10 along the second direction Y. In this way, the film application drive mechanisms 32 of the two film application devices 30 can share the space in the second direction Y, which helps to improve space utilization and facilitates the miniaturization of the film application equipment 1.

[0041] In other examples, there are four membrane separation devices 20 and four film application devices 30. Two membrane separation devices 20 are located on one side of the feeding device 10 along the first direction X and along the second direction Y. The other two membrane separation devices 20 are located on the other side of the feeding device 10 along the first direction X and along the second direction Y. Two film application devices 30 are located on one side of the feeding device 10 along the second direction Y and along the first direction X, respectively close to the two membrane separation devices 20 on one side of the second direction Y. The other two film application devices 30 are located on the other side of the feeding device 10 along the second direction Y and along the first direction X, respectively close to the two membrane separation devices 20 on the other side of the second direction Y. The large number of membrane separation devices 20 and film application devices 30, distributed along the outer periphery of the feeding device 10, helps to shorten the transfer path of each film application drive mechanism 32, improves space utilization, and facilitates the miniaturization of the film application equipment 1.

[0042] The feeding device 10 can feed one product 2 at a time, and at least two film-applying devices 30 can apply film 3 to different positions of the same product 2. The feeding device 10 can also feed multiple products 2 at the same time, and at least two film-applying devices 30 can apply film 3 to different products 2 respectively.

[0043] The film-applying device 1 provided in this embodiment of the application, by setting multiple film separation devices 20 and multiple film-applying devices 30, can not only realize the automatic separation and automatic application of film 3, but also apply film to different positions of the same product 2 or multiple different products 2 simultaneously, which is beneficial to improving film-applying efficiency and effect, and enhancing the consistency of product quality. The multiple film separation devices 20 are distributed on both sides of the feeding device 10 along the first direction X, and the film-applying drive mechanism 32 of the film-applying device 30 is located on one side of the feeding device 10 along the second direction Y. The film separation devices 20 and the feeding device 10 share at least a portion of the space in the second direction Y, and the film-applying drive mechanism 32 and the feeding device 10 share at least a portion of the space in the first direction X. The structural layout of the feeding device 10, film separation devices 20, and film-applying devices 30 is more compact and reasonable, which helps to shorten the transfer path of the film-applying drive mechanism 32, further improves film-applying efficiency, and also helps to improve space utilization, reduce the space occupied by the film-applying device 1, and facilitates the miniaturization of the film-applying device 1.

[0044] In some embodiments, the feeding device 10 includes a storage component 11 movably disposed along a third direction Z, the storage component 11 being configured to store a plurality of products 2 stacked along a third direction Z.

[0045] The material storage component 11 moves along the third direction Z, which can sequentially move multiple products 2 to the film application station, thereby realizing continuous feeding of batch products, which is beneficial to improving feeding efficiency and thus improving film application efficiency.

[0046] For example, each time the storage component 11 moves upward, it moves the uppermost product 2 to the film-applying station. After all the products 2 in the storage component 11 have been filmed, the storage component 11 moves downward to replenish the storage component 11.

[0047] The storage component 11 can be a storage plate, storage tray, storage bin, or other suitable structure. The structure of the storage component 11 can be adapted to the shape of the product 2. For example, the film-applying equipment 1 is used to apply film to cardboard that can form a packaging box, and the storage component 11 is a storage plate.

[0048] In some embodiments, refer to Figure 1 and Figure 3 The film-applying device 1 includes a support platform 40, a material storage component 11, a film separation device 20, and a film-applying device 30, all of which are disposed on the upper side of the support platform 40 along the third direction Z. The feeding device 10 includes a feeding drive mechanism 12, which includes a feeding drive component 121 and a telescopic rod 122. The telescopic rod 122 passes through the support platform 40 along the third direction Z, and its two ends are respectively connected to the material storage component 11 and the feeding drive component 121. The feeding drive component 121 is disposed on the lower side of the support platform 40 along the third direction Z and is configured to drive the telescopic rod 122 to extend and retract along the third direction Z.

[0049] The feeding device 10 also includes a mounting structure 13, which is fixed to the lower side of the support platform 40. Exemplarily, the mounting structure 13 is connected to the support platform 40 and is suspended in the air. The feeding drive component 121 is fixed to the mounting structure 13 to improve its stability.

[0050] This embodiment of the application makes full use of the space under the support platform 40 to accommodate the feeding drive component 121. The feeding drive component 121 does not occupy the space on the upper side of the support platform 40, which is beneficial to providing more arrangement space for the feeding device 10, multiple film separation devices 20 and multiple film application devices 30, and facilitates the miniaturization of the film application equipment 1. The telescopic rod 122 passes through the support platform 40 and connects the storage component 11 and the feeding drive component 121, which can drive the storage component 11 to rise and fall, thereby smoothly feeding and replenishing materials.

[0051] In some embodiments, refer to Figure 3 The feeding device 10 also includes a plurality of guide rods 14, one end of which is fixedly connected to the storage component 11, and the guide rods 14 are movably inserted through the support platform 40 in the third direction Z.

[0052] The guide rod 14 can support the storage component 11 and guide the lifting and lowering of the storage component 11, which helps to improve the stability of the lifting and lowering process of the storage component 11.

[0053] Optionally, the telescopic rod 122 is connected to the middle position of the storage component 11, and multiple guide rods 14 are distributed along the outer periphery of the telescopic rod 122, which helps to evenly support the storage component 11, further improve the stability of the lifting and lowering of the storage component 11, and improve the jamming phenomenon during the lifting and lowering process.

[0054] In some embodiments, the loading device 10 further includes a detection component (not shown) configured to detect height information of the product 2 at its uppermost position along the third direction Z relative to the support platform 40. The film application device 1 also includes a control device 50 connected to the detection component and configured to control the operation of the loading drive component 121 based on the height information.

[0055] The detection component can be a contact or non-contact sensor capable of detecting the height information of product 2, such as a laser sensor, ultrasonic sensor, radar sensor, etc.

[0056] The detection component can be located on the upper side of the storage component 11 along the third direction Z, or it can be located on either side of the storage component 11 along the first direction X or the second direction Y.

[0057] The control device 50 controls the operation of the feeding drive component 121 according to the height information, thereby controlling the extension distance of the telescopic rod 122 along the third direction Z. This helps to achieve the height consistency of the uppermost product 2 at the film application station, reduces the phenomenon of the film 3 not being applied tightly, or the excessive force between the film 3 and the product 2 causing damage to the film 3 or the product 2, and helps to improve the film application effect and increase the production yield of product film application.

[0058] In some embodiments, refer to Figure 3 The storage component 11 is plate-shaped. The storage component 11 includes a first plate portion 111 and a second plate portion 112 disposed along the second direction Y. Along the first direction X, the first plate portion 111 partially protrudes beyond two edges of the second plate portion 112 in the first direction X. The feeding device 10 includes at least two first positioning structures 16, which are disposed on at least one side of the first plate portion 111 along the second direction Y, and respectively disposed on both sides of the second plate portion 112 along the first direction X.

[0059] There can be one or more first plate portions 111. There can also be one or more second plate portions 112. Optionally, there can be one first plate portion 111 and one second plate portion 112; along the second direction Y, the first plate portion 111 is closer to the film application driving mechanism 32 than the second plate portion 112. Alternatively, there can be two second plate portions 112, with the first plate portion 111 located between and connecting the two second plate portions 112 along the second direction Y.

[0060] Optionally, there are two first positioning structures 16, which are respectively located on both sides of the second plate portion 112 along the first direction X.

[0061] The first positioning structure 16 may include a positioning plate extending in a third direction Z. The first positioning structure 16 is connected to the support platform 40.

[0062] Along the first direction X, the second plate portion 112 is located between two first positioning structures 16. The two first positioning structures 16 can position the product 2 carried on the storage component 11 in the first direction X, which helps to improve the accuracy of the film application position.

[0063] The first plate portion 111 includes three parts, one of which is connected to one side of the second plate portion 112 along the second direction Y, and the other two parts protrude from the two edges of the second plate portion 112 along the first direction X. The material storage component 11 has notches on both sides of the first direction X. These notches can provide clearance space for the first positioning structure 16, so that the first positioning structure 16 and the material storage component 11 share the space along the first direction X, which is beneficial to further improve the structural compactness of the film application device 1.

[0064] In some embodiments, the position of the first positioning structure 16 in the first direction X can be adjusted.

[0065] Optionally, the first positioning structure 16 is connected to the support platform 40 by screws. The support platform 40 is provided with a plurality of connecting holes spaced apart along the first direction X, and the position of the first positioning structure 16 in the first direction X is adjusted by connecting the first positioning structure 16 to different connecting holes.

[0066] Alternatively, the first positioning structure 16 is connected to the support platform 40 via a slide rail and a locking structure, and its position in the first direction X is adjusted by sliding the first positioning structure 16.

[0067] By adjusting the position of the first positioning structure 16 in the first direction X, the distance between the two first positioning structures 16 set along the first direction X can be adjusted, thereby facilitating the effective positioning of products 2 of different sizes.

[0068] In some embodiments, the feeding device 10 may further include a second positioning structure 17, which is disposed on at least one side of the storage component 11 along the second direction Y, for positioning the product 2 on the storage component 11 in the second direction Y.

[0069] The second positioning structure 17 can be one or more.

[0070] The position of the second positioning structure 17 in the second direction Y can be adjusted.

[0071] In some embodiments, refer to Figure 4 and Figure 5 The membrane separation device 20 includes a membrane support structure 21 and a sensing element 22. The membrane support structure 21 includes a support portion 211, configured to carry the membrane 3 separated from the conveyor belt 4. The support portion 211 has a through hole 2111, which extends through the support portion 211 along a third direction Z. The sensing element 22 is disposed on the lower side of the support portion 211 along the third direction Z and corresponds to the through hole 2111. The sensing element 22 is configured to sense the membrane 3 and generate a sensing signal.

[0072] Optionally, the diaphragm support structure 21 further includes a support frame 212, which is directly or indirectly connected to the upper side of the support platform 40. The support portion 211 is disposed on the support frame 212. The support frame 212 raises the support portion 211 to a predetermined position, which is beneficial for the support portion 211 to support the diaphragm 3.

[0073] The upper side of the support 211 may be provided with multiple grooves 2112 to reduce the contact area between the support 211 and the diaphragm 3, reduce the adhesion between the diaphragm 3 and the support 211, and facilitate the adsorption mechanism 31 to pick up the diaphragm 3 on the support 211.

[0074] The through hole 2111 is located in the middle of the support 211, which helps the sensing component 22 to sense the diaphragm 3 more effectively and reduces the possibility of not being able to sense the diaphragm 3 due to differences in size or position of the diaphragm 3.

[0075] Optionally, the sensing component 22 includes a photoelectric sensor.

[0076] After sensing the membrane 3, the sensing component 22 generates a sensing signal, which can be used to control the operation of the membrane separation device 20 so that only a preset number of membranes 3 are separated to the membrane support structure 21. The sensing signal can also be used to control the operation of the film application device 30 so that the film application device 30 can accurately pick up the membrane 3 and transfer it to the feeding device 10, which helps to improve the control accuracy of automated film application.

[0077] In some embodiments, refer to Figure 4The membrane separation device 20 also includes an unwinding mechanism 23, a winding mechanism 24, and a peeling plate 25. The unwinding mechanism 23 is configured to unwind the feed strip 4, and the winding mechanism 24 is configured to wind the feed strip 4 to separate the bottom film 5 from the membrane 3. The peeling plate 25 has a first end 25a around which the feed strip 4 is wound. Along the first direction X, the first end 25a is closer to the membrane support structure 21 than the unwinding mechanism 23 and the winding mechanism 24. On the conveying path of the feed strip 4, the first end 25a is located between the unwinding mechanism 23 and the winding mechanism 24.

[0078] The unwinding mechanism 23 includes an unwinding roller on which the strip 4 is wound. The winding mechanism 24 includes a winding roller on which the base film 4 is wound. The unwinding roller and the winding roller can rotate synchronously under the action of a single drive mechanism to tension the strip 4 and the base film 5. Alternatively, the unwinding roller and the winding roller can be driven by separate drive mechanisms.

[0079] Optionally, the unwinding mechanism 23 and the winding mechanism 24 are arranged along the third direction Z, which can improve the space utilization in the third direction Z and save the space occupied by the membrane separation device 20 in the first direction X.

[0080] The unwinding mechanism 23 unwinds the strip 4 and conveys it to the first end 25a. When the strip 4 passes the first end 25a, the film 3 of the strip 4 is peeled off under the action of the peeling plate 25. The remaining bottom film 5 continues to be conveyed and wound up to the winding mechanism 24. The first end 25a is the end of the peeling plate 25 that is close to the film support structure 21 along the first direction X. The peeled film 3 can move to the film support structure 21 under the action of the bottom film 5.

[0081] Since the first end 25a is closer to the film support structure 21 than the unwinding mechanism 23 and the winding mechanism 24, the conveying direction of the strip 4 changes significantly when it passes through the first end 25a. Therefore, the peeling plate 25 can separate the film 3 from the bottom film 5.

[0082] To better support the diaphragm 3, the height of the diaphragm support structure 21 along the third direction Z is no higher than the height of the peeling plate 25. Optionally, the top of the diaphragm support structure 21 is flush with the first end 25a of the peeling plate 25 along the third direction Z.

[0083] In some embodiments, refer to Figure 1 The film application equipment 1 also includes a control device 50, which is connected to the sensing component 22 and is configured to receive sensing signals and control the start and stop of the unwinding mechanism 23 and the rewinding mechanism 24 according to the sensing signals.

[0084] The control device 50 is electrically or signal-connected to the sensing component 22.

[0085] Optionally, when the sensing component 22 detects the presence of a film 3 on the film support structure 21, it generates a sensing signal and sends it to the control device 50. After receiving the sensing signal, the control device 50 controls the unwinding mechanism 23 and the winding mechanism 24 to stop operating, thereby reducing the possibility of multiple films 3 accumulating on the film support structure 21. After the film application device 30 picks up the film 3 from the film support structure 21, the sensing component 22 does not detect a film 3 and does not generate a sensing signal. The control device 50 then controls the unwinding mechanism 23 and the winding mechanism 24 to start operating, thereby separating the new film 3 onto the film support structure 21.

[0086] The sensing element 22 senses the film 3, and the control device 50 controls the start and stop status of the unwinding mechanism 23 and the rewinding mechanism 24, which is conducive to the safe and orderly production and operation of the film application equipment 1 and reduces the probability of equipment failure.

[0087] In some embodiments, refer to Figure 1 The film application device 1 also includes a first support mechanism 60 and two second support mechanisms 70 spaced apart along a first direction X. The first support mechanism 60 and the two second support mechanisms 70 are located on the same side of the feeding device 10 along a second direction Y. Along the first direction X, the first support mechanism 60 is located between the two second support mechanisms 70. The control device 50 is supported on the first support mechanism 60, and there are two film application drive mechanisms 32, each supported on one of the two second support mechanisms 70.

[0088] Optionally, the first support mechanism 60 includes a support rod. Using the support rod to support the control device 50 not only ensures support stability but also simplifies the structure and reduces space occupation. The second support mechanism 70 includes a support frame. Supporting the film application drive mechanism 32 with the support frame improves the stability of the support rod, reduces the shaking of the film application drive mechanism 32, and thus improves the accuracy of the film application position.

[0089] Optionally, the height of the control device 50 is higher than the height of the second support mechanism 70, which helps to reduce interference.

[0090] The first support mechanism 60 and the two second support mechanisms 70 are located on the same side of the feeding device 10 along the second direction Y, leaving the other side of the feeding device 10 along the second direction Y free for operators to adjust or repair the film-applying equipment 1. Utilizing the space between the two second support mechanisms 70 to arrange the first support mechanism 60 helps to further improve the structural compactness and the rationality of the structural layout.

[0091] In the embodiments of this application, the feeding drive mechanism 12, the film application drive mechanism 32, etc., can adopt common drive structures in the art, such as motor gear drive mechanism, cylinder drive mechanism, etc., which will not be described in detail here.

[0092] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
