Description

Technical Field

[0001] This application relates to the field of film application technology, and more specifically, to a film application mechanism and film application equipment. Background Technology

[0002] Currently, when automating film application on products, a feeding mechanism typically picks up the film to be applied and places it above the application position, then presses it down to apply the film. For some products, different shapes and thicknesses of film may need to be applied. Existing feeding mechanisms have some problems. Feeding mechanisms with only a single feeding end pick up multiple pieces of film at the same time. Some film may be properly picked up, while others may not, leading to inconvenience in control. Furthermore, thicker film usually comes into contact with the product first, making it difficult for users to know the adsorption and application status of each piece of film. Utility Model Content

[0003] In view of this, this application provides a film-applying mechanism and film-applying equipment to solve the technical problems of inconvenience in the material-picking mechanism for picking up and applying multiple pieces of film material, which affects the film-applying quality.

[0004] One embodiment of this application provides a film-applying mechanism. The film-applying mechanism is connected to an actuator to apply film to a product under the actuation of the actuator. The film-applying mechanism includes a connecting structure and an adsorption structure. The connecting structure is used to connect to the actuator. The adsorption structure is disposed on the connecting structure. The adsorption structure includes a mounting member and multiple adsorption members. The multiple adsorption members are disposed on the mounting member. The adsorption members are used to adsorb film material. Different adsorption members are configured to provide adsorption force relatively independently.

[0005] The adsorption structure incorporates multiple adsorption elements, each providing independent adsorption force. This allows each element to adsorb a single piece of film material, with adsorption and desorption occurring independently and without interference. If some film material is not properly adsorbed, it can be easily re-adsorbed. For films of varying thicknesses, the position of the adsorption elements along the film thickness direction can be adjusted, ensuring that films of different thicknesses can simultaneously contact the product and complete the application. This film application mechanism is suitable for simultaneously applying multiple film materials to a product, thus improving the quality of the application.

[0006] In some embodiments, the film-applying mechanism further includes a sensor. The sensor is disposed between the connecting structure and the mounting member. The sensor is used to sense and acquire the pressure value applied to the product. When the film-applying mechanism moves with the actuator to apply film to the product, the adsorption member applies pressure to the product, and the sensor senses and acquires this pressure value.

[0007] During film application, the entire application mechanism applies pressure to the product under the action of the actuator to maintain pressure. Sensors that detect the pressure feedback from the product are placed between the connecting structure and the mounting components. This helps ensure that the application pressure is within a preset range, thereby improving the application quality and effectively preventing insufficient pressure from causing incomplete application or excessive pressure from damaging the adsorption components and the product.

[0008] In some embodiments, the adsorption element has adsorption holes and air channels. One end of the air channel is connected to the adsorption hole, and the other end of the air channel is used to connect to an air source. The adsorption hole is used to adsorb the membrane material. The air channels of each adsorption element are not interconnected.

[0009] Each adsorbent is independent of the others, and their respective gas channels are not interconnected. This allows for the provision of a separate gas source for each adsorbent, enabling independent control of adsorption or desorption for each adsorbent. If an adsorbent fails to adsorb properly, desorption of that membrane material can be performed without adjusting other membrane materials, thus improving the flexibility of the adsorption structure during use.

[0010] In some embodiments, the adsorption element is provided with adsorption holes and air channels. One end of the air channel communicates with the adsorption holes, and the other end of the air channel is used to connect to an air source. The adsorption holes are used to adsorb membrane material. The adsorption structure also includes multiple openable and closable valves. Each valve is located in an air channel to control the opening and closing of that air channel. The air channels of each adsorption element are interconnected.

[0011] The gas channels of each adsorbent are interconnected, allowing a single gas source to supply gas to multiple adsorbents. If only a portion of the adsorbents needs to be used to adsorb the membrane material, the operation of that portion of the adsorbents can be controlled by adjusting the valves on the gas channels.

[0012] In some embodiments, the film application mechanism further includes a plurality of first elastic elements. An adsorption element is slidably connected to the mounting element. Each first elastic element is used to apply an elastic force to an adsorption element.

[0013] The suction element, slidably connected to the mounting component, is subjected to an elastic force provided by the first elastic element. When the suction element contacts the product, the first elastic element reduces the impact force exerted directly on the product by the suction element. Furthermore, the first elastic element can adjust the pressure applied by the suction element to the product. The buffering effect provided by the first elastic element effectively prevents hard contact between the suction element and the product, thus preventing damage to both.

[0014] In some embodiments, the mounting element includes a mounting element body and a connecting portion. The connecting portion is connected to the mounting element body. The sensing element has a sensing side. The sensing side is connected to the connecting portion to sense and acquire a pressure value. The adsorption element is connected to the mounting element body and is slidable relative to the mounting element body. The adsorption end of the adsorption element passes through the mounting element body to adsorb film material.

[0015] The mounting component provides a connection point for the sensing side of the sensor, and the adsorption component and the first elastic component are installed within it. When the film-applying mechanism applies the film, the adsorption component contacts the product. Under the action of the actuator, pressure is applied to the product, causing the adsorption component to slide relative to the main body of the mounting component and compress the first elastic component. The first elastic component provides elastic force to the adsorption component for cushioning. The sensor obtains the pressure value feedback from the product and uses the actuator to drive the film-applying mechanism to keep the pressure value applied to the product within a preset range, thus maintaining the pressure value for pressure retention.

[0016] In some embodiments, a first elastic member is disposed within the mounting body and between the connecting portion and the adsorption member. One end of the first elastic member abuts against the adsorption member, and the other end of the first elastic member abuts against the connecting portion, thereby compressing the first elastic member.

[0017] The first elastic element is compressed between the adsorption element and the connecting part, so that the first elastic element always provides elastic force to the adsorption element. The first elastic element is always in a compressed state, which can also effectively extend the service life of the first elastic element.

[0018] In some embodiments, the connection structure includes a connector and an adapter assembly. The connector is used to connect to an actuator. The adapter assembly includes a first adapter, an abutment, a second adapter, a first slider, a second slider, and a second elastic member. The first adapter and the connector are fixedly connected. The first adapter includes an abutment portion and a buffer portion spaced apart along a first direction. The abutment and the first adapter are fixedly connected. The abutment is disposed between the abutment portion and the buffer portion along the first direction. The abutment is spaced apart from the abutment portion along the first direction. The abutment and the buffer portion abut against each other. The second adapter is spaced apart from the first adapter along the first direction. The second adapter is connected to a sensor. The first slider is fixedly disposed between the abutment and the second adapter. The second slider is fixedly connected to the buffer portion and slidably connected to the first slider along the first direction. The second elastic member is compressed between the abutment and the abutment portion along the first direction. The second elastic member is used to apply an elastic force to the abutment. When the second slider slides along the first direction and approaches the abutment portion, the second elastic member is compressed.

[0019] The connector and actuator are fixedly connected, thereby moving the entire film application mechanism along with the actuator. The second elastic element provides cushioning for the entire film application mechanism, further reducing the impact force from the adsorption component directly acting on the product.

[0020] In some embodiments, the film-applying mechanism further includes a film-tearing structure. The film-tearing structure is disposed on the connecting structure and spaced apart from the adsorption structure. The film-tearing structure is used to separate different layers of the film material after film application.

[0021] The film material consists of different film layers, generally including at least an upper film and a lower film. The lower film is the film layer attached to the surface of the product, while the upper film is release paper. The film-applying mechanism applies pressure to the product to apply and maintain the pressure. After the film is applied, the actuator moves the film-applying mechanism away from the product. The film-peeling structure can assist in peeling the upper and lower films so that the upper film can be recycled.

[0022] One embodiment of this application provides a film-applying device. The film-applying device includes an actuator, a controller, and a film-applying mechanism. The actuator is connected to a connecting structure. The controller is connected to a sensor and the actuator.

[0023] The actuator drives the film-applying mechanism to apply film to the product. The sensor receives the pressure value applied to the product by the adsorption component. The controller controls the movement of the actuator based on this pressure value, so that the film-applying mechanism applies pressure to the product within a preset range to perform the film-applying operation. This can effectively ensure the quality of film application and also help avoid damage to equipment and products. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0034] The definitions of "first direction" and "second direction" are for the purpose of describing the relative positional relationship of related structures, and do not mean that "first direction" and "second direction" need to depend on the related structures involved in the above definitions.

[0035] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0036] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present. When a component is considered to be "located" on another component, it can be directly located on the other component or there may be an intervening component present.

[0037] Embodiments of this application provide a film-applying mechanism. The film-applying mechanism is connected to an actuator to apply film to a product under the actuation of the actuator. The film-applying mechanism includes a connecting structure and an adsorption structure. The connecting structure is used to connect to the actuator. The adsorption structure is disposed on the connecting structure. The adsorption structure includes a mounting member and multiple adsorption elements. The multiple adsorption elements are disposed on the mounting member. The adsorption elements are used to adsorb film material. Different adsorption elements are configured to provide adsorption force relatively independently.

[0038] The adsorption structure incorporates multiple adsorption elements, each providing independent adsorption force. This allows each element to adsorb a single piece of film material, with adsorption and desorption occurring independently and without interference. If some film material is not properly adsorbed, it can be easily re-adsorbed. For films of varying thicknesses, the position of the adsorption elements along the film thickness direction can be adjusted, ensuring that films of different thicknesses can simultaneously contact the product and complete the application. This film application mechanism is suitable for simultaneously applying multiple film materials to a product, thus improving the quality of the application.

[0039] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] Please see Figure 1 and Figure 2 One embodiment of this application provides a film-applying mechanism 100. The film-applying mechanism 100 is connected to an actuator (not shown) to apply film to a product under the actuation of the actuator. The film-applying mechanism 100 includes a connecting structure 1 and an adsorption structure 2. The connecting structure 1 is connected to the actuator. The adsorption structure 2 is disposed on the connecting structure 1. The adsorption structure 2 includes a mounting member 21 and a plurality of adsorption members 22. The plurality of adsorption members 22 are disposed on the mounting member 21. The adsorption members 22 are used to adsorb film material. Different adsorption members 22 are configured to provide adsorption force relatively independently.

[0041] The adsorption structure 2 is provided with multiple adsorption elements 22, and each adsorption element 22 is provided with an independent adsorption force. In this way, each adsorption element 22 can adsorb a piece of film material, and the adsorption and desorption of each piece of film material are completed independently without interference. If some film material is not properly adsorbed, it is easy to re-adsorb. For film materials of different thicknesses, the position of the adsorption element 22 along the thickness direction of the film material can be adjusted, which helps to ensure that film materials of different thicknesses can simultaneously contact the product and complete the film application. The film application mechanism 100 of this application is suitable for simultaneously applying multiple pieces of film material to a product, which helps to improve the film application quality.

[0042] In some embodiments, the film-applying mechanism 100 further includes a sensor 3. The sensor 3 is disposed between the connecting structure 1 and the mounting member 21. The sensor 3 is used to sense and acquire the pressure value applied to the product. When the film-applying mechanism 100 moves with the actuator to apply film to the product, the adsorption member 22 applies pressure to the product, and the sensor 3 senses and acquires the pressure value.

[0043] During film application, the entire film application mechanism 100 applies pressure to the product under the action of the actuator to maintain pressure. A sensor 3, capable of sensing the pressure feedback from the product, is installed between the connecting structure 1 and the mounting component 21. This helps ensure that the film application pressure is within a preset range, thereby improving the film application quality and effectively preventing insufficient pressure from causing incomplete application or excessive pressure from damaging the adsorption component 22 and the product.

[0044] Please see Figure 1 , Figure 2 and Figure 5 In some embodiments, the adsorbent 22 is provided with adsorption holes 221 and air channels 222. One end of the air channel 222 is connected to the adsorption hole 221, and the other end of the air channel 222 is used to connect to an air source. The adsorption hole 221 is used to adsorb the membrane material. The air channels 222 of each adsorbent 22 are not interconnected.

[0045] like Figure 5 In the illustrated embodiment, each adsorbent 22 is independent of the others, and their respective air channels 222 are not interconnected. This facilitates the provision of a separate air source for each adsorbent 22, allowing for independent control of adsorption or desorption for each adsorbent 22. If an adsorbent 22 fails to adsorb properly, desorption of that membrane material can be performed without adjusting other membrane materials, thus improving the flexibility of the adsorption structure 2 during use.

[0046] In some embodiments, the adsorbent 22 is provided with adsorption holes 221 and air channels 222. One end of the air channel 222 communicates with the adsorption holes 221, and the other end of the air channel 222 is used to connect to an air source. The adsorption holes 221 are used to adsorb membrane material. The adsorption structure 2 also includes a plurality of openable and closable valves (not shown in the figure). Each valve is located in an air channel 222 to control the opening and closing of the air channel 222 of the adsorbent 22. The air channels 222 of each adsorbent 22 are interconnected.

[0047] The air channels 222 of each adsorbent 22 are interconnected, and a single air source can supply air to multiple adsorbents 22. If only a portion of the adsorbents 22 need to be used to adsorb the membrane material, the valves on the air channels 222 can be controlled to make that portion of the adsorbents 22 work.

[0048] Please continue reading Figure 5 In some embodiments, the film application mechanism 100 further includes a plurality of first elastic elements 4. The adsorption member 22 is slidably connected to the mounting member 21. Each first elastic element 4 is used to apply an elastic force to an adsorption member 22.

[0049] The adsorption member 22, which is slidably connected to the mounting member 21, can be subjected to elastic force provided by the first elastic member 4. When the adsorption member 22 contacts the product, the first elastic member 4 can reduce the impact force caused by the adsorption member 22 directly acting on the product. The first elastic member 4 can also adjust the pressure applied by the adsorption member 22 to the product. The buffering effect provided by the first elastic member 4 can effectively prevent hard contact between the adsorption member 22 and the product, which could damage the adsorption member 22 and the product.

[0050] In some embodiments, the mounting member 21 includes a mounting member body 211 and a connecting portion 212. The connecting portion 212 is connected to the mounting member body 211. The sensing member 3 has a sensing side 301. The sensing side 301 is connected to the connecting portion 212 to sense and acquire a pressure value. The adsorption member 22 is connected to the mounting member body 211 and is slidable relative to the mounting member body 211. The adsorption end of the adsorption member 22 passes through the mounting member body 211 to adsorb film material.

[0051] Mounting member 21 provides a connection point for the sensing side 301 of sensing member 3, and the adsorption member 22 and the first elastic member 4 are installed within it. When the film application mechanism 100 applies the film, the adsorption member 22 contacts the product. Under the action of the actuator, pressure is applied to the product, and the adsorption member 22 slides relative to the mounting member body 211, compressing the first elastic member 4. The first elastic member 4 provides elastic force to the adsorption member 22 to achieve cushioning. Sensing member 3 obtains the pressure value feedback from the product and drives the film application mechanism 100 through the actuator to keep the pressure value applied to the product within a preset range, so that the film application mechanism 100 can maintain the pressure value for pressure holding.

[0052] In some embodiments, the first elastic member 4 is disposed within the mounting body 211 and between the connecting portion 212 and the adsorption member 22. One end of the first elastic member 4 abuts against the adsorption member 22, and the other end of the first elastic member 4 abuts against the connecting portion 212, thereby compressing the first elastic member 4.

[0053] The first elastic element 4 is compressed between the adsorption element 22 and the connecting part 212, so that the first elastic element 4 always provides elastic force to the adsorption element 22. The first elastic element 4 is always in a compressed state, which can also effectively extend the service life of the first elastic element 4.

[0054] like Figure 2 and Figure 5In the illustrated embodiment, there are two adsorption elements 22, and correspondingly two first elastic elements 4. This application does not specifically limit the number or shape of the adsorption elements 22. In this application and its embodiments, multiple adsorption elements 22 are configured to provide adsorption force relatively independently, suitable for situations requiring the application of different film materials. When the pressure required for film application and pressure holding for different film materials within a certain thickness range is within the range of the sensing element 3, a single sensing element 3 can be used, as in this embodiment. Of course, when the thickness difference between different film materials is large, to ensure the quality of film application, a separate sensing element 3 can be provided for each adsorption element 22; this application does not limit this in its embodiments.

[0055] Please see Figure 3 and Figure 4 In some embodiments, the connection structure 1 includes a connector 11 and a transition assembly 12. The connector 11 is used to connect to an actuator. The transition assembly 12 includes a first transition member 121, an abutment member 122, a second transition member 123, a first sliding member 124, a second sliding member 125, and a second elastic member 126. The first transition member 121 and the connector 11 are fixedly connected. The first transition member 121 includes an abutment portion 1211 and a buffer portion 1212 spaced apart along a first direction Z. The abutment member 122 and the first transition member 121 are fixedly connected. The abutment member 122 is disposed between the abutment portion 1211 and the buffer portion 1212 along the first direction Z. The abutment member 122 and the buffer portion 1212 abut against each other. The second transition member 123 is spaced apart from the first transition member 121 along the first direction Z. The second adapter 123 is connected to the sensing element 3. The first sliding member 124 is fixedly disposed between the abutment member 122 and the second adapter 123. The second sliding member 125 is fixedly connected to the buffer portion 1212 and slidably connected to the first sliding member 124 along the first direction Z. The second elastic member 126 is compressed between the abutment member 122 and the abutment portion 1211 along the first direction Z. The second elastic member 126 is used to apply an elastic force to the abutment member 122. When the second sliding member 125 slides along the first direction Z and approaches the abutment portion 1211, the second elastic member 126 is compressed.

[0056] The connector 11 is fixedly connected to the actuator, thereby driving the entire film application mechanism 100 to move with the actuator. The second elastic member 126 is used to provide a buffering effect on the entire film application mechanism 100, further reducing the impact force brought about by the adsorption member 22 directly acting on the product.

[0057] Understandably, the first elastic element 4 and the second elastic element 126 are always in a compressed state during the operation of the film-applying mechanism 100. This serves two purposes: firstly, to ensure a stable cushioning effect; and secondly, because if the first elastic element 4 and the second elastic element 126 could also be stretched, the process of stretching and then compressing would accelerate fatigue. Therefore, it is necessary to ensure that the first elastic element 4 and the second elastic element 126 are always in a compressed state.

[0058] Please continue reading Figure 1 and Figure 2 In some embodiments, the film-applying mechanism 100 further includes a film-tearing structure 5. The film-tearing structure 5 is disposed on the connecting structure 1 and spaced apart from the adsorption structure 2. The film-tearing structure 5 is used to separate different layers of the film material after the film is applied.

[0059] The film material includes different film layers, generally including at least an upper film and a lower film. The lower film is the film layer attached to the surface of the product, while the upper film is release paper. The film application mechanism 100 applies pressure to the product to apply and maintain the pressure. After the film application is completed, the actuator drives the film application mechanism 100 away from the product. The film peeling structure 5 can assist in peeling the upper and lower films so that the upper film can be recycled.

[0060] In some embodiments, the film-peeling structure 5 includes a first peeling member 51, a second peeling member 52, and a driving member 53. The first peeling member 51 and the second peeling member 52 are spaced apart along a second direction X. The first peeling member 51 is fixedly disposed on the connecting structure 1. The second peeling member 52 and the driving member 53 are connected. The driving member 53 is used to drive the second peeling member 52 to move closer to or away from the first peeling member 51 along the second direction X. When the second peeling member 52 moves closer to the first peeling member 51 along the second direction X, the second peeling member 52 and the first peeling member 51 clamp the film layer to be peeled to separate it from the film layer attached to the product. The second direction X intersects the first direction Z.

[0061] Understandably, the tear-off structure 5 plays an auxiliary role in separating the different layers of the film material. The side of the lower film facing the product is adhesive. After the film application mechanism 100 completes the pressure-holding film application, the lower film adheres to the product surface. If the film application mechanism 100 is directly moved away from the product to complete the separation of the different film layers, it may affect the film application quality and be less efficient. Using the tear-off structure 5 can quickly complete the separation of the different film layers of the film material without affecting the film application quality as much as possible.

[0062] Please continue reading Figure 1 and Figure 2The first peeling member 51 has a first inclined surface 511. The first inclined surface 511 is provided with several adsorption holes. The first peeling member 51 is used to adsorb the film layer to be peeled from the film material. The second peeling member 52 has a second inclined surface 521, which is parallel to the first inclined surface 511. The area of ​​the upper film is larger than that of the lower film, that is, the upper film will have an auxiliary part for easy peeling. When separating the upper and lower films, as the driving member 53 drives the second peeling member 52 closer to the first peeling member 51 along the second direction X, the second peeling member 52 will adhere to the auxiliary part and push the upper film to be adsorbed by the first peeling member 51. Under the combined action of the first peeling member 51 and the second peeling member 52, the upper and lower films are separated. The actuator drives the film-applying mechanism 100 away from the product, thereby completing the separation of different film layers of the film material. Then the adsorption member 22 and the first peeling member 51 change from negative pressure to positive pressure, blowing away the upper film for recycling.

[0063] In some embodiments, the second inclined surface 521 is provided with protrusions. The protrusions can increase the friction of the second inclined surface 521 to prevent the upper film from slipping off the second inclined surface 521.

[0064] like Figure 1 As shown, the film-tearing structure 5 also includes a mounting plate 54, which is fixed to the connecting structure 1. A driving member 53 and a first peeling member 51 are fixedly mounted on the mounting plate 54. The driving member 53 can be a cylinder, and the second peeling member 52 is located at the telescopic end of the cylinder so that it can move closer to or further away from the first peeling member 51 as the cylinder extends and retracts. Alternatively, the driving member 53 can be a lead screw mechanism and a motor, with the second peeling member 52 located on the lead screw mechanism. The motor drives the lead screw mechanism to move the second peeling member 52 along the second direction X.

[0065] One embodiment of this application provides a film-applying device (not shown in the figure). The film-applying device includes an actuator (not shown in the figure), a controller (not shown in the figure), and a film-applying mechanism 100. The actuator is connected to a connection structure 1. The controller is communicatively connected to the actuator and is used to control the operation of the actuator and the film-applying mechanism 100 respectively. The controller is also communicatively connected to a sensor 3.

[0066] The actuator drives the film-applying mechanism 100 to move along the first direction Z to approach or move away from the product. Specifically, driven by the actuator, the film-applying mechanism 100 approaches the product along the first direction Z and applies pressure to the product. The product is pressed, and the sensor 3 senses and acquires the pressure value applied to the product by the adsorption member 22 in real time. The controller controls the movement speed and direction of the actuator based on this pressure value, so that the film-applying mechanism 100 applies pressure to the product within a preset range to perform the film-applying operation. This can effectively ensure the quality of film application and also help avoid damage to equipment and products.

[0067] Understandably, how the controller controls the actuator and the film-applying mechanism 100 based on the pressure value sensed by the sensor 3 is a common principle in the relevant field and will not be elaborated here. The actuator can be a robotic arm or a linear motion mechanism.

[0068] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
