Description

Technical Field

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

[0002] During automated transportation or assembly, protective films need to be applied to certain surfaces of the product to prevent scratches and damage to the product's appearance during transport. However, existing automated film application equipment requires the application mechanism to avoid protrusions on raised surfaces, increasing the machine's movement and reducing application efficiency. Utility Model Content

[0003] In view of this, this application provides an application roller mechanism and a film application device to solve the problem that the complex operation of the application mechanism during the film application process leads to a decrease in film application efficiency.

[0004] One embodiment of this application provides an attachment rolling mechanism for attaching a protective film to a product. The protective film has at least a first portion and a second portion sequentially along a first direction. The attachment rolling mechanism includes a material-picking assembly and a rolling assembly. The material-picking assembly is used to pick up the protective film and position it facing the product. The rolling assembly is used to roll the protective film onto the product along the first direction. The rolling assembly includes at least two rolling members. The two rolling members are a first rolling member and a second rolling member. The first rolling member is used to roll the first portion. The second rolling member is used to roll the second portion. The first rolling member and the second rolling member are sequentially arranged in a direction opposite to the first direction, and along the first direction, the first rolling member is closer to the first portion than the second rolling member. The first rolling member and the second rolling member are configured to be movable along a second direction to move closer to or further away from the protective film. The second direction intersects the first direction.

[0005] The material-picking assembly first extracts the protective film and positions it towards the product. The application rolling mechanism moves to directly above the product, positioning the first portion of the protective film above the corresponding area on the product. The first rolling member presses down to apply the film. The entire application rolling mechanism moves along a first direction to roll the first portion of the protective film onto the product. When the first portion of the protective film is applied to the product, the first rolling member moves away from the protective film along a second direction, and the second rolling member moves closer to the second portion of the protective film along the second direction to perform a rolling operation. The entire application rolling mechanism moves along the first direction to roll the second portion of the protective film onto the product. The application rolling mechanism provided in this application, for products with raised surfaces, divides the protective film to be applied to the product into two parts along the first direction, and uses two rolling members to perform rolling operations on the corresponding parts respectively. The first and second rollers are arranged sequentially in the opposite direction to the rolling direction, with the first roller closer to the first part of the protective film. This arrangement allows for a continuous and smooth application process of different parts of the protective film, reducing operation time. The operation of the roller assembly is relatively simple, which helps to improve the efficiency of film application.

[0006] In some embodiments, the attachment rolling mechanism further includes a drive assembly. The drive assembly includes at least two drive members. The two drive members are a first drive member and a second drive member. The first drive member is connected to the first rolling member to drive the first rolling member to move in a second direction. The second drive member is connected to the second rolling member to drive the second rolling member to move in the second direction.

[0007] The first and second rolling elements are driven by independent drive components to move closer to or further away from the protective film along the second direction. When the first rolling element moves away from the protective film along the second direction, the second rolling element can simultaneously or in advance move closer to the protective film along the second direction. This further ensures a continuous and smooth application process for different parts of the protective film.

[0008] In some embodiments, when the projection of the first portion overlaps the projection of the second portion along the first direction, the projection of the first rolling element overlaps the projection of the second rolling element along the direction opposite to the first direction.

[0009] When the projection of the first part covers the projection of the second part along the first direction, the protective film part with a longer length is applied first. Correspondingly, the axial length of the first rolling element is also greater than that of the second rolling element, which helps to ensure that the rolling assembly can perform a single translational film application operation.

[0010] In some embodiments, the first direction is parallel to the width direction of the protective film.

[0011] Roller-applied components start applying film from the long side of the product, which greatly improves the efficiency of film application compared to starting from the short side.

[0012] In some embodiments, the application rolling mechanism further includes a guide assembly. The guide assembly is used to guide the first rolling member and the second rolling member to move in a second direction.

[0013] The guide assembly can guide the movement of the first and second rolling elements in the second direction, while also ensuring the precision and accuracy of their movement in the second direction, thereby limiting their movement in other directions.

[0014] In some embodiments, the application rolling mechanism further includes a frame. A guiding assembly includes a first guide and a second guide. The first and second guides are disposed on the frame. The first rolling member includes a first mounting member and a first roller. The first roller is rotatably connected to the first mounting member, and the rotation axis of the first roller is perpendicular to a first direction and perpendicular to a second direction. The second rolling member includes a second mounting member and a second roller. The second roller is rotatably connected to the second mounting member, and the rotation axis of the second roller is perpendicular to both the first and second directions. The first mounting member is slidably connected to the first guide member along the second direction. The second mounting member is slidably connected to the second guide member along the second direction.

[0015] In some embodiments, the material handling assembly includes an adsorption seat. The adsorption seat has an adsorption surface. The adsorption surface is used to adsorb a protective film and faces the product. The adsorption seat has a plurality of adsorption holes. The adsorption seat includes a first fixture plate and a second fixture plate. The second fixture plate is disposed on the first fixture plate. A gas storage cavity is provided between the second fixture plate and the first fixture plate. The second fixture plate has an adsorption surface. The gas storage cavity communicates with the plurality of adsorption holes. The first fixture plate has a ventilation channel. One end of the ventilation channel communicates with the gas storage cavity, and the other end of the ventilation channel is used to communicate with the adsorption device.

[0016] The protective film is extracted using vacuum adsorption, which can stably extract protective films of different shapes, without being limited by the shape of the protective film.

[0017] In some embodiments, a plurality of adsorption pores are uniformly arranged on the adsorption seat. The distance between two adjacent adsorption pores is less than or equal to 1 mm and greater than or equal to 0.5 mm. The diameter of the adsorption pore is less than or equal to 1 mm and greater than or equal to 0.5 mm.

[0018] Adjusting the density of the adsorption pores can improve the adsorption force and stability of the adsorption seat.

[0019] One embodiment of this application provides a film application device. The film application device includes a driving mechanism and an application roller mechanism. The driving mechanism is used to drive the application roller mechanism to move along a first direction and in the opposite direction.

[0020] The entire application rolling mechanism is driven by the drive mechanism to roll along the first direction, thereby causing the first rolling element and / or the second rolling element to apply the protective film to the product along the first direction. The first rolling element and the second rolling element themselves rotate around the axis to apply the protective film evenly and flatly to the product. Their movements do not interfere with each other, which helps to ensure that the first rolling element and / or the second rolling element always perform the application operation at the optimal angle.

[0021] In some embodiments, the film application equipment further includes a lifting mechanism. The lifting mechanism is used to carry the product and can lift it in a second direction to bring the product closer to the protective film.

[0022] For products to be coated with film, a lifting mechanism is used to lift them up for film application. After film application, the products are lowered and flow out for other processes. This eliminates the need for additional product positioning and helps improve film application efficiency. Attached Figure Description

[0038] Embodiments of this application provide an attachment rolling mechanism for attaching a protective film to a product. The protective film has at least a first portion and a second portion sequentially along a first direction. The attachment rolling mechanism includes a material-picking assembly and a rolling assembly. The material-picking assembly is used to pick up the protective film and position it facing the product. The rolling assembly is used to roll the protective film onto the product along the first direction. The rolling assembly includes at least two rolling members. The two rolling members are a first rolling member and a second rolling member. The first rolling member is used to roll the first portion. The second rolling member is used to roll the second portion. The first rolling member and the second rolling member are sequentially arranged in a direction opposite to the first direction, and along the first direction, the first rolling member is closer to the first portion than the second rolling member.

The first and second rollers are arranged sequentially in the opposite direction to the rolling direction, with the first roller closer to the first part of the protective film. This arrangement allows for a continuous and smooth application process of different parts of the protective film, reducing operation time. The operation of the roller assembly is relatively simple, which helps to improve the efficiency of film application.

[0040] 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.

[0041] Please see Figure 1 and Figure 2 One embodiment of this application provides an attachment rolling mechanism 100 for attaching a protective film 1 to a product 2. Please refer to this embodiment in conjunction with... Figure 4The protective film 1 has at least a first portion 101 and a second portion 102 sequentially along a first direction X. The application rolling mechanism 100 includes a material-taking assembly 3 and a rolling assembly 4. The material-taking assembly 3 is used to pick up the protective film 1 and position it facing the product 2. The rolling assembly 4 is used to roll the protective film 1 onto the product 2 along the first direction X. The rolling assembly 4 includes at least two rolling elements. The two rolling elements are a first rolling element 41 and a second rolling element 42. The first rolling element 41 is used to roll the first portion 101. The second rolling element 42 is used to roll the second portion 102. The first rolling element 41 and the second rolling element 42 are sequentially arranged in a direction opposite to the first direction X, and along the first direction X, the first rolling element 41 is closer to the first portion 101 than the second rolling element 42. The first rolling element 41 and the second rolling element 42 are configured to be movable along a second direction Z to move closer to or further away from the protective film 1. The second direction Z intersects the first direction X.

[0042] The material-picking assembly 3 first picks up the protective film 1 and positions it towards the product 2. The application rolling mechanism 100 moves to directly above the product 2, positioning the first portion 101 of the protective film 1 above the corresponding area on the product 2. The first rolling member 41 presses down to perform the film application operation. The entire application rolling mechanism 100 moves along the first direction X to drive the first rolling member 41 to roll the first portion 101 of the protective film 1 onto the product 2. When the first portion 101 of the protective film 1 is applied to the product 2, the first rolling member 41 moves away from the protective film 1 along the second direction Z, and the second rolling member 42 moves closer to the second portion 102 of the protective film 1 along the second direction Z to perform the rolling operation. The entire application rolling mechanism 100 moves along the first direction X to drive the second rolling member 42 to roll the second portion 102 of the protective film 1 onto the product 2. The application rolling mechanism 100 provided in this application, for a product 2 with raised surfaces, divides the protective film 1 to be applied to the product 2 into two parts along the first direction X, and performs rolling operations on the corresponding parts by two rolling members respectively. The first rolling member 41 and the second rolling member 42 are arranged sequentially in the opposite direction to the rolling direction, and the first rolling member 41 is closer to the first part 101 of the protective film 1. This layout allows the application process of different parts of the protective film 1 to be completed continuously and smoothly, reducing operation time. The operation of the rolling assembly 4 is relatively simple, which helps to improve the film application efficiency.

[0043] Product 2 can be electronic products such as mobile phones. For mobile phones, there will be a protrusion at the location of the rear camera. Protective film 1 is as follows: Figure 4 The device shown has a first portion 101 and a second portion 102. The protective film 1 is attached to the back of the mobile phone, excluding the camera, by the attachment rolling mechanism 100 of this application. Understandably, due to the different shapes of the protrusions, the protective film 1 may also have a third portion along the first direction X, corresponding to a number of three rolling elements.

[0044] In some embodiments, the application rolling mechanism 100 further includes a drive assembly 5. The drive assembly 5 includes at least two drive members. The two drive members are a first drive member 51 and a second drive member 52. The first drive member 51 is connected to the first rolling member 41 to drive the first rolling member 41 to move along the second direction Z. The second drive member 52 is connected to the second rolling member 42 to drive the second rolling member 42 to move along the second direction Z.

[0045] The first rolling element 41 and the second rolling element 42 are driven by independent driving elements so that they can move closer to or further away from the protective film 1 along the second direction Z. When the first rolling element 41 moves away from the protective film 1 along the second direction Z, the second rolling element 42 can move closer to the protective film 1 synchronously or in advance along the second direction Z. In this way, the application process of different parts of the protective film 1 can be further guaranteed to be continuous and smooth.

[0046] To avoid interference between the movement of the first rolling element 41 and the second rolling element 42 along the second direction Z, a certain distance is maintained between them along the first direction X. When the application rolling mechanism 100 is working, as the first rolling element 41 is about to finish rolling the first part 101, the second driving element 52 drives the second rolling element 42 to move in advance along the second direction Z to approach the protective film 1. At this time, the first rolling element 41 and the second rolling element 42 simultaneously roll the first part 101. When the first rolling element 41 finishes rolling the first part 101 and moves away from the protective film 1 along the second direction Z to avoid the protrusions on the product 2, the second rolling element 42 is already performing the rolling application operation. This ensures continuous and smooth rolling application of the protective film 1, and prevents poor application such as bubbles or wrinkles between the first part 101 and the second part 102.

[0047] In some embodiments, when the projection of the first portion 101 covers the projection of the second portion 102 along the first direction X, the projection of the first rolling member 41 covers the projection of the second rolling member 42 along the direction opposite to the first direction X.

[0048] When the projection of the first part 101 overlaps the projection of the second part 102 along the first direction X, the longer protective film 1 part is applied first. Correspondingly, the axial length of the first rolling member 41 is also greater than that of the second rolling member 42, which helps to ensure that the rolling assembly 4 can perform a single translational film application operation. Figure 1 and Figure 2 As shown, the longer rolling element is the first rolling element 41, and the shorter rolling element is the second rolling element 42. Understandably, in the third direction Y, when the length of the first portion 101 near the first rolling element 41 is less than the length of the second portion 102 in the third direction Y, the axial length of the first rolling element 41 will be correspondingly less than the axial length of the second rolling element 42.

[0049] In some embodiments, the first direction X is parallel to the width direction of the protective film 1.

[0050] The rolling assembly 4 applies the film starting from the long side of product 2, which greatly improves the film application efficiency compared to applying the film starting from the short side.

[0051] In the embodiments of this application, the first direction X represents a unidirectional direction, namely the rolling direction of the attachment rolling mechanism 100, which is also the width direction of the protective film 1; the second direction Z represents a bidirectional direction, namely the first rolling member 41 and the second rolling member 42 approaching or moving away from the protective film 1; and a third direction Y is defined, which is parallel to the length direction of the protective film 1 (the axial direction of the first rolling member 41 and the second rolling member 42). The first direction X, the second direction Z, and the third direction Y intersect each other.

[0052] In some embodiments, the attachment rolling mechanism 100 further includes a guide assembly 6. The guide assembly 6 is used to guide the first rolling member 41 and the second rolling member 42 to move along a second direction Z.

[0053] The guide assembly 6 can guide the movement of the first rolling member 41 and the second rolling member 42 in the second direction Z, and at the same time ensure the precision and accuracy of the movement of the first rolling member 41 and the second rolling member 42 in the second direction Z, so as to limit the movement of the first rolling member 41 and the second rolling member 42 in other directions.

[0054] In some embodiments, the attachment rolling mechanism 100 further includes a frame 7. The guide assembly 6 includes a first guide 61 and a second guide 62. The first guide 61 and the second guide 62 are disposed on the frame 7. The first rolling member 41 includes a first mounting member 411 and a first roller 412. The first roller 412 is rotatably connected to the first mounting member 411, and the rotation axis of the first roller 412 is perpendicular to a first direction X and perpendicular to a second direction Z. The second rolling member 42 includes a second mounting member 421 and a second roller 422. The second roller 422 is rotatably connected to the second mounting member 421, and the rotation axis of the second roller 422 is perpendicular to both the first direction X and the second direction Z. The first mounting member 411 is slidably connected to the first guide member 61 along the second direction Z. The second mounting member 421 is slidably connected to the second guide member 62 along the second direction Z. The rotation axes of the first roller 412 and the second roller 422 are the same as the third direction Y.

[0055] Please refer to this as well. Figure 3The guide assembly 6 consists of two sets: two first guide members 61 and two second guide members 62. The two first guide members 61 and two second guide members 62 are located on opposite sides of the frame 7 along the third direction Y, which improves the stability of the first rolling member 41 and the second rolling member 42 moving along the second direction Z. The first guide member 61 includes a first slide rail 611 and a first slider 612. The first slide rail 611 is located on the frame 7, and the first slider 612 is slidably connected to the first slide rail 611 along the second direction Z. The first mounting member 411 is connected to the first slider 612. The second guide member 62 includes a second slide rail 621 and a second slider 622. The second slide rail 621 is located on the frame 7, and the second slider 622 is slidably connected to the second slide rail 621 along the second direction Z. The second mounting member 421 is connected to the second slider 622.

[0056] In some embodiments, both the first driving member 51 and the second driving member 52 are cylinders, and the telescopic ends of the two cylinders are connected to the first rolling member 41 and the second rolling member 42 to directly drive the first rolling member 41 and the second rolling member 42 to move along the second direction Z, specifically connected to the first mounting member 411 and the second mounting member 421. Further, along the third direction Y, the two cylinders are positioned between the two sets of guide assemblies 6 to further improve the stability of the movement of the first rolling member 41 and the second rolling member 42 along the second direction Z.

[0057] In some embodiments, the material handling assembly 3 includes an adsorption seat 31. The adsorption seat 31 has an adsorption surface 3101. The adsorption surface 3101 is used to adsorb the protective film 1 and faces the product 2. The adsorption seat 31 is provided with a plurality of adsorption holes 3102. The adsorption seat 31 includes a first fixture plate 311 and a second fixture plate 312. The second fixture plate 312 is disposed on the first fixture plate 311. A gas storage cavity is provided between the second fixture plate 312 and the first fixture plate 311. The second fixture plate 312 has an adsorption surface 3101. The gas storage cavity communicates with the plurality of adsorption holes 3102. The first fixture plate 311 is provided with a ventilation channel. One end of the ventilation channel communicates with the gas storage cavity, and the other end of the ventilation channel is used to communicate with the adsorption device.

[0058] The protective film 1 is extracted by vacuum adsorption, which can stably extract protective films 1 of different shapes, without being limited by the shape of the protective film 1.

[0059] When the adsorption seat 31 picks up the protective film 1, it does so as... Figure 1 and Figure 4 In the example shown, the part of the first part 101 that is first attached to the product 2 should be located outside the adsorption seat 31. In this way, when the first roller 41 presses down to attach the product, it can press a part of the protective film 1 onto the product 2 so that the attachment roller mechanism 100 can move along the first direction X.

[0060] In some embodiments, a plurality of adsorption holes 3102 are uniformly arranged on the adsorption seat 31. The distance between two adjacent adsorption holes 3102 is less than or equal to 1 mm and greater than or equal to 0.5 mm. The diameter of the adsorption hole 3102 is less than or equal to 1 mm and greater than or equal to 0.5 mm. The adsorption hole 3102 has an open state and a closed state, and each adsorption hole 3102 is configured to be able to switch independently between the open state and the closed state.

[0061] Multiple adsorption pores 3102 are evenly arranged on the adsorption seat 31, allowing the protective film 1 to be uniformly adsorbed onto the adsorption seat 31. Adjusting the spacing between two adjacent adsorption pores 3102 can adjust the density of the multiple adsorption pores 3102 on the adsorption seat 31, thereby improving the adsorption force and stability of the adsorption seat 31. Adjusting the pore diameter of the adsorption pores 3102 can improve the adsorption force of the adsorption pores 3102 on the protective film 1. Furthermore, the switching between the open and closed states of each adsorption pore 3102 is independent. The open state means that the adsorption pore 3102 has adsorption force, and the closed state means that the adsorption pore 3102 cannot adsorb the protective film 1 or the adsorption force is too low to adsorb the protective film 1. The opening and closing of each adsorption pore 3102 is independent, so that according to the shape of the protective film 1, some adsorption pores 3102 are in the open state to adsorb the protective film 1, while others are in the closed state. This improves the applicability of the adsorption seat 31. In actual operation, when some adsorption holes 3102 are not in use, they can be covered with tape to keep them closed. Alternatively, each adsorption hole 3102 can be independently switched between open and closed states through a program. When the first rolling member 41 and the second rolling member 42 perform rolling operations along the first direction X, the first rolling member 41 (or the second rolling member 42) rolls the protective film 1 onto the product 2. Under the pressure applied by the first rolling member 41 and the adhesive force of the protective film 1, the protective film 1 will gradually transfer from the adsorption seat 31 to the product 2 and adhere to it, without adjusting the switch of the adsorption device.

[0062] One embodiment of this application provides a film application device (not shown in the figure). The film application device includes a drive mechanism (not shown in the figure) and an application roller mechanism 100. The drive mechanism is used to drive the application roller mechanism 100 to move along a first direction X and in the opposite direction of the first direction X.

[0063] The entire application and rolling mechanism 100 is driven by the drive mechanism to move along the first direction X to perform rolling, thereby causing the first rolling member 41 and / or the second rolling member 42 to attach the protective film 1 to the product 2 along the first direction X. The first rolling member 41 and the second rolling member 42 themselves rotate around their axial direction to evenly and smoothly attach the protective film 1 to the product 2. Their movements do not interfere with each other, helping to ensure that the first rolling member 41 and / or the second rolling member 42 always perform the application operation at the optimal angle. Furthermore, by controlling the speed at which the drive mechanism moves along the first direction X, the first rolling member 41 and the second rolling member 42 can move along the second direction Z to a preset position.

[0064] In some embodiments, the film application device further includes a lifting mechanism (not shown in the figure). The lifting mechanism is used to carry the product 2 and can lift it along the second direction Z to bring the product 2 closer to the protective film 1.

[0065] Since the roller assembly 4 is in contact with the protective film 1, the product 2 to be coated is lifted by the lifting mechanism for coating. After coating, it descends and flows out for other processes, eliminating the need for additional positioning of the product 2 and improving coating efficiency. Specifically, the product 2 is placed on the lifting mechanism, which lifts it along the second direction Z until the product 2 reaches a preset position. At this point, the protective film 1 is located between the product 2 and the roller assembly 4 in the second direction Z. Then, the drive mechanism moves the coating roller assembly 100 to the preset position for the roller coating operation. After coating is completed, the protective film 1 is completely coated on the product 2, and the lifting mechanism descends along the second direction Z, allowing the product 2 to flow to other processes.
