Description

Technical Field

[0001] The utility model relates to a material vehicle and a film pressing mechanism, belonging to the technical field of film lamination. Background Art

[0002] Lamination involves applying a soft film to a hard printed surface. High temperature and high pressure create a strong bond between the film and the printed material. The film provides waterproofing and dustproofing, enhances strength, and protects the printed image. For example, bank cards are often produced using this lamination process.

[0003] During the lamination process, the soft film and the object to be laminated are squeezed by hot rollers and bonded together at high temperatures. The soft film is usually in the form of a roll for processing. Figure 1 This is a schematic diagram of existing lamination equipment and processes. Figure 2 yes Figure 1 Top view of the middle soft membrane. Figure 1 As shown, the film supply structure 10 is used to continuously supply the soft film 11, and the piece to be coated 30 is continuously conveyed under the soft film 11. The soft film 11 and the piece to be coated 30 are pressed together at high temperature when they are conveyed to the pressure roller 20. After the film pressing by the pressure roller 20 is completed, the combination of the soft film 11 and the piece to be coated 30 will also be cut by the cutting device 40, for example, it will be cut into the size of a bank card. In the operation of the assembly line, the pressure roller 20 needs to stop rotating to cut the combination 12 of the soft film 11 and the piece to be coated 30, that is, the feeding of the soft film 11 and the piece to be coated 30 must be stopped so that the combination 12 can be accurately cut while it is in a stationary state. However, since the pressure roller 20 is always in a high temperature state, the part of the product pressed by the pressure roller 20 will be damaged due to the long-term high temperature, and this part will become waste 13 (see Figure 2 ), which increases production costs. At the same time, stopping feeding will also increase processing time, resulting in a decrease in production capacity. Utility Model Content

[0004] The purpose of the utility model is to provide a material vehicle and a film pressing mechanism, which can cut the combination during the feeding process, thereby avoiding waste caused by the high temperature of the pressing roller or a decrease in production capacity caused by stopping the feeding.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a material vehicle for transporting a workpiece to be coated and combining it with a soft film to form a combined body, the material vehicle comprising:

[0006] The material vehicle body is used to carry at least one part to be coated;

[0007] At least one cutting structure is arranged on the material vehicle body and corresponds one-to-one to the workpiece to be coated. Each of the cutting structures can be moved along the first horizontal direction on the material vehicle body. Each of the cutting structures is controlled to cut the soft film after the soft film is combined with the surface of the workpiece to be coated, and at least one cutting structure is used to cut and separate the soft film on the material vehicle body and the soft film outside the material vehicle body.

[0008] Furthermore, the material vehicle body includes a plurality of the cutting structures, which are arranged at intervals along the second horizontal direction, and the parts to be coated are placed between two adjacent cutting structures, and the second horizontal direction is perpendicular to the first horizontal direction.

[0009] Furthermore, the cutting structure includes a cutting knife and a driving assembly for driving the cutting knife to move, and an end portion of the cutting knife is formed with a beveled edge portion for cutting.

[0010] The present invention also provides a film pressing mechanism, which comprises:

[0011] The film supply structure transports the soft film along the second horizontal direction;

[0012] a hot pressing roller, arranged on a conveying path of the soft film;

[0013] Several material carts as described above move along the second horizontal direction to transport the parts to be coated, and are configured in turn at the hot pressing roller to extrude the parts to be coated and the soft film at high temperature under the action of the hot pressing roller to form a combination, and the cutting structure is used to cut the soft film between two adjacent parts to be coated after the parts to be coated and the soft film are combined.

[0014] Furthermore, a gap is formed between two adjacent material carts to provide moving space for the cutting knife.

[0015] Furthermore, one of the parts to be coated is arranged on each of the material carts, and the cutting structure is provided on a side of the material cart opposite to the second horizontal direction.

[0016] Further, the cutting structure is configured to move along the axial direction of the hot pressing roller to cut the soft film.

[0017] Further, the cutting knife is configured to enter the gap from the outside of the gap to cut the soft membrane or extend into the gap to pierce the soft membrane and cut the soft membrane.

[0018] Furthermore, the laminating mechanism also includes a conveying line for conveying a plurality of the material carts.

[0019] Furthermore, the conveyor line is a rotary conveyor line, and a blanking component and a loading component are provided on the rotary path of the rotary conveyor line. The blanking component is used to realize the blanking of the combination, and the loading component is used to realize the loading of the part to be coated.

[0020] The beneficial effect of the present invention is that by arranging a cutting structure on the material vehicle, the soft film cutting process can be carried out while the material vehicle is moving, avoiding the need for the material vehicle to stop and wait during the cutting process, thereby greatly improving work efficiency.

[0021] The present application also provides a film pressing mechanism, which is provided by setting up a material cart to transport the workpiece to be coated, and setting up a cutting structure on the material cart. After the soft film and the workpiece to be coated are compounded to form a combination on the material cart under the high-temperature extrusion of the hot pressing roller, the material cart drives the combination to continue moving. At this time, the cutting structure cuts the soft film between two adjacent material carts / workpieces to be coated to separate them. Since the cutting structure is set on the material cart, the material cart, the soft film and the cutting structure are relatively stationary in the feeding direction of the material cart, avoiding the need to stop feeding for cutting and separation, thereby solving the problem of the hot pressing roller damaging the soft film and reducing production capacity due to stopping feeding, thereby reducing production costs and improving production efficiency.

[0022] The present application also provides a control method for a film pressing mechanism, which controls the film supply structure and each material cart to transport the soft film and the workpiece to be coated along the second horizontal direction respectively. Under the high temperature of the hot pressing roller and the mutual extrusion with the material cart, the soft film and the workpiece to be coated are squeezed to form a combination, and the cutting structure on the material cart is controlled to cut the soft film between two adjacent combinations, thereby solving the problem of needing to stop feeding to cut the soft film, avoiding damage to the combination due to the high temperature of the hot pressing roller, reducing production costs, and improving production efficiency.

[0023] The above description is only an overview of the technical solution of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0047] Please refer to Figure 3 In one embodiment of the present application, a material cart is used to transport a workpiece 30 to be coated and combined with a soft film 11 to form a combined body 12. The material cart 50 includes a material cart body 51 and a cutting structure 52. The material cart body 51 is used to carry at least one workpiece 30 to be coated. At least one cutting structure 52 is provided on the material cart body 51 and corresponds to the workpiece 30 to be coated. Each cutting structure 52 can be provided on the material cart body 51 along a first horizontal direction (i.e., Figure 3 The material cart 50 is provided with only one cutting structure 52, which is positioned at the edge of the material cart 51 and is used to separate the soft film 11 on the material cart 51 from the soft film 11 outside the material cart 51, thereby facilitating the transfer of the combined body 12 to the next process. Furthermore, since the cutting structure 52 moves with the material cart, the need to stop and wait for the soft film 11 to be cut is avoided, facilitating automated processing and improving work efficiency.

[0048] In other embodiments, each material vehicle 50 includes a plurality of cutting structures 52, and the plurality of cutting structures 52 are arranged along the second horizontal direction (ie, Figure 3 The two cutting structures 52 are arranged at intervals (in the direction indicated by the arrow b in the middle), and the workpiece 30 to be coated is placed between two adjacent cutting structures 52, and the second horizontal direction is perpendicular to the first horizontal direction. After the soft film 11 is combined with the workpiece 30 to be coated to form a combination 12, each material cart 50 uses the cutting structure 52 thereon to cut the soft film 11 between each adjacent combination 12 on the material cart body 51 and cut and separate the soft film 11 at the edge of the material cart 50, thereby separating each combination 12 separately, facilitating the subsequent fine processing of the combination 12. Of course, in addition to the cutting structure 52 used to cut and separate the soft film 11 on the material cart body 51 and the soft film 11 outside the material cart body 51, the remaining cutting structures 52 can also be set according to the contour of the workpiece 30 to be coated, so that the cutting structure 52 can cut along the contour of the workpiece 30 to be coated during cutting, thereby achieving cutting of the combination 12.

[0049] The cutting structure 52 includes a cutting blade and a drive assembly that drives the cutting blade. The end of the cutting blade is formed with a beveled blade portion for cutting the soft film 11. The beveled blade design can effectively reduce resistance during the cutting process. The beveled blade portion reduces the vertical contact area between the cutting blade and the soft film 11, thereby reducing the cutting force per unit area. When cutting the soft film 11, the beveled blade portion can more smoothly enter and cut the soft film 11. By dispersing the cutting force, the cutting blade can operate more efficiently during the cutting process, improving overall cutting efficiency and reducing the driving force required by the drive assembly.

[0050] Among them, the driving assembly includes a slide rail and a driving member. The cutting knife is fixed on the slider of the slide rail. The driving member drives the slider to move on the slide rail to drive the cutting knife to move along the axial direction of the hot pressing roller 20 to cut the soft film 11. The slide rail cooperates with the slider to drive the cutting knife to move while guiding the movement of the cutting knife to prevent the cutting knife from damaging or cutting the combination 12.

[0051] Please refer to Figure 4 and Figure 5 In one embodiment of the present application, the film pressing mechanism includes a film supply structure 10, a hot pressing roller 20 and a plurality of material carts 50.

[0052] In this embodiment, the film supply structure 10 is arranged along the second horizontal direction ( Figure 5The film supply structure 10 includes a roller on which the soft film 11 is wound. The roller can be driven by a power element to rotate to actively transport the soft film 11, or it can be driven by a material cart 50 to rotate and thus passively transport the soft film 11. The roller is driven by the material cart 50 to rotate and thus passively transport the soft film 11. Specifically, the roller is driven by the material cart 50 to rotate and thus passively transport the soft film 11 as follows: by fixing the end of the soft film 11 to the front end of the material cart 50, the material cart 50 moves along the second horizontal direction, thereby driving the soft film 11 to move in the second horizontal direction, thereby driving the rolling rotation and thus transporting the soft film 11. After the first material cart 50 cooperates with the hot pressing roller 20 to high-temperature extrude the soft film 11 and the workpiece to be coated 30 to form a combined body 12, when the soft film 11 is cut to separate the combined body 12, at least one material cart 50 just presses the soft film 11 and the workpiece to be coated 30 against each other, so that the material cart 50 can continue to drive the film supply structure 10 to rotate and transport the soft film 11 in the second horizontal direction.

[0053] The hot pressing roller 20 is arranged on the conveying path of the soft film 11. The hot pressing roller 20 includes a roller body and a heating component arranged in the roller body. The heating component is used to keep the roller body within the temperature range required for film pressing. This is a prior art and will not be described in detail here.

[0054] Several material carts 50 move along the second horizontal direction to transport the workpieces 30 to be coated, and are sequentially configured at the hot-pressing rollers 20 to press the workpieces 30 to be coated and the soft film 11 at high temperature to form a combined body 12. Each material cart 50 is provided with a cutting structure 52, which is used to cut the soft film 11 between two adjacent workpieces 30 to be coated after the workpieces 30 to be coated and the soft film 11 are combined. A placement groove adapted to the shape of the workpieces 30 to be coated is formed on the material cart 50. The workpieces 30 to be coated are placed in the placement groove, and the distance between the workpieces 30 to be coated and the hot-pressing rollers 20 is slightly smaller than the thickness of the soft film 11. When the soft film 11 is in contact with the workpieces 30 to be coated, it softens under the high temperature of the hot-pressing rollers 20, and is adhered to the workpieces 30 to be coated by the mutual squeezing of the workpieces 30 to be coated and the hot-pressing rollers 20. In addition, in order to prevent the piece to be coated 30 from moving or to cooperate with subsequent cutting, a fixed structure can be set in the placement groove to fix the piece to be coated 30. For example, a supporting member can be set on the side of the placement groove to support the piece to be coated 30 in the placement groove, or a suction cup or adsorption member can be set at the bottom of the placement groove to adsorb the piece to be coated 30 in the placement groove.

[0055] In this embodiment, each material cart 50 is provided with a workpiece 30 to be coated and a cutting structure 51. The cutting structure 52 is used to cut the soft film 11 between two adjacent material carts 50. That is, one of the two adjacent material carts 50 is provided with a cutting structure 52 on the side close to the other material cart 50. The cutting structure 52 cuts the soft film 11 between the two material carts 50, thereby separating the two combined bodies 12 on the two material carts 50. Of course, multiple workpieces 30 to be coated 30 can also be placed on each material cart 50, with the multiple workpieces 30 to be coated forming a group. The cutting structure 52 cuts the soft film 11 between two adjacent material carts 50, thereby separating the two groups of combined bodies 12 on the two material carts 50.

[0056] Please refer to Figure 5 The cutting structure 52 is configured to cut along the axis direction of the hot pressing roller 20 (ie Figure 5 The hot pressing roller 20 moves in the direction indicated by the arrow a in the middle to cut the soft film 11. To ensure the molding quality of the combined body 12, the axis of the hot pressing roller 20 is generally arranged perpendicular to the second horizontal direction on a horizontal plane. Since the cutting structure 52 is arranged on the material cart 50 and moves along the second horizontal direction with the material cart 50, the cutting structure 52 cuts the soft film 11 along the axis of the hot pressing roller 20, which can shorten the cutting path of the cutting structure 52 and improve cutting efficiency. Of course, in other embodiments, depending on the shape of the workpiece 30 to be coated or the processing requirements, the cutting structure 52 can also cut the soft film 11 along other directions. The cutting direction can be set as needed, as long as it can achieve the above-mentioned effect, and is not specifically limited here.

[0057] A gap is formed between two adjacent material carts 50 to provide moving space for the cutting knife. In this embodiment, the material cart 50 is a rectangular platform, and the two adjacent material carts 50 are arranged at intervals. The gap between the two material carts 50 extends along the axial direction of the hot pressing roller 20, and the width of the gap is slightly greater than or equal to the thickness of the cutting knife, ensuring that the cutting knife has enough moving space to move from one end of the gap to the other end, so that what is left after cutting is basically a formed and usable combination 12, reducing the waste of the soft film 11.

[0058] In this embodiment, the cutting blade is configured to enter the gap from the outside of the gap to cut the soft film 11. The drive assembly is disposed within the side wall of the material cart 50 on the side closest to the gap. The cutting blade is L-shaped, with a portion of the cutting blade located within the side wall to connect to the slider. When not cutting the soft film 11, the cutting blade is located outside the gap to prevent damage from colliding with the hot pressing roller 20. At the same time, the width of the material cart 50 can be made equal to the length of the hot pressing roller 20, thereby maximizing the effective extrusion molding area of ​​the material cart 50. Of course, in other embodiments, the drive assembly can also be disposed at the bottom of the material cart 50.

[0059] Preferably, the cutting knife is provided with two beveled blades, which are arranged opposite to each other, so that the cutting knife does not need to return after completing the cutting. When cutting is needed next time, the cutting knife returns and cuts the soft film 11, which can effectively reduce energy consumption and reduce costs.

[0060] The working process of the film pressing mechanism is as follows: Please refer to Figure 6 and Figure 7 The front end of the soft film 11 is connected to the side of the first material car 50 close to the hot pressing roller. The material car 20 moves toward the hot pressing roller in sequence, while the film structure 10 is supplied. At the same time, the film structure 10 conveys the soft film 11 to cooperate with the material car 50 to move; until the first material car 50 moves to the bottom of the hot pressing roller 20, please refer to Figure 8 and Figure 9 The soft film 11 on the first material car 50 first contacts the hot pressing roller 20. Under the high temperature of the hot pressing roller 20, the soft film 11 softens. As the first material car 50 continues to move, the softened soft film 11 is squeezed by the first material car 50 and the hot pressing roller 20 and is combined with the workpiece 30 to form a combined body 12. Until the first material car 50 is completely separated from the hot pressing roller 20 and the cutting structure 52 does not touch the hot pressing roller 20, please refer to Figure 10 and Figure 11 The driving assembly drives the cutting knife to move from the outside of the gap between the two material carts 50 toward the inside of the gap. The oblique blade of the cutting knife contacts the side of the soft film 11 in the gap and cuts the soft film 11 under the drive of the driving assembly until the cutting knife moves to the outside of the other end of the gap, that is, the soft film 11 between the first material cart 50 and the next material cart 50 is completely cut.

[0061] In other embodiments, the drive assembly further includes a lifting drive member, which is connected between the cutting blade and the slider. When not cutting, the lifting drive member descends to allow the cutting blade to be stored in the gap. When cutting, the lifting drive member drives the cutting blade to extend out of the gap to pierce the soft film 11, and cuts the soft film 11 under the drive of the drive member. Of course, the cutting structure 52 can also be in other forms, such as setting a cutting blade of the same length as the gap, and driving the cutting blade to lift and cut the soft film 11 by the lifting drive member, or setting a cutting blade of the same length as the gap in the vertical direction, setting the cutting blade outside the gap, and driving the cutting blade to rotate by the rotating drive member to cut the soft film 11 from above the soft film 11. The specific form of the cutting structure 52 can be set according to needs, as long as it can achieve the above-mentioned effect, and is not specifically limited here.

[0062] In other embodiments, a plurality of parts to be coated 30 are spaced apart along the second horizontal direction on each material cart 50, and a plurality of cutting structures 51 are provided correspondingly, wherein one cutting structure 51 is provided on the side of the material cart 50 close to the upstream material cart 50, and the remaining cutting structures 51 are provided between two adjacent parts to be coated 30 on the material cart 50. After the soft film 11 and the parts to be coated 30 are combined to form a combined body 12, the cutting structure 51 can cut the soft film 11 between the two parts to be coated 30, thereby dividing the combined body 12 into separate parts for use in subsequent processing steps. Preferably, the cutting structure 51 is designed according to the contour of the parts to be coated 30, so that the cutting structure 51 can cut according to the contour of the parts to be coated 30 to remove the excess soft film 11 on the combined body 12.

[0063] Please refer to Figure 12 In this embodiment, the laminating mechanism also includes a transmission line for conveying a plurality of material carts 50. The material carts 50 are arranged at intervals on the transmission line and move along the second horizontal direction through the transmission line to drive the plurality of material carts 50 to move along the second horizontal direction in turn to cooperate with the hot pressing roller 20 to extrude and compound the soft film 11 and the part to be coated 30 at high temperature to form a combination 12.

[0064] Preferably, the conveyor line is a rotary conveyor line 60, and a unloading component and a loading component are arranged on the rotating path of the rotary conveyor line 60. The unloading component is used to realize the unloading of the combination 12, and the loading component is used to realize the loading of the part to be coated 30. The rotary line is in the shape of a runway, and the hot pressing roller 20 and the film supply structure 10 can be respectively arranged in a group at the upstream end of the straight section of the rotary line, and the small material component and the loading component are sequentially arranged at the downstream end of the straight section of the rotary line, so that the material cart 50 can be rotated for use to improve work efficiency. Among them, the rotary line, unloading component and loading component are all existing technologies and will not be elaborated here.

[0065] Please refer to Figure 13 The present application also provides a control method for the above film pressing mechanism, which comprises the following steps:

[0066] S1, controlling the film supply structure 10 and each material cart 50 to transport the soft film 11 and the workpiece to be coated 30 respectively along the second horizontal direction. Under the high temperature of the hot pressing roller 20 and the mutual extrusion between the hot pressing roller 20 and the material cart 50, the soft film 11 and the workpiece to be coated 30 are squeezed to form a combined body 12;

[0067] S2 . When the material vehicle 50 moves to a preset position downstream of the hot pressing roller 20 , the cutting structure 52 on the material vehicle 50 is controlled to cut the soft film 11 between two adjacent combined bodies 12 to separate the two combined bodies 12 .

[0068] The above control method further includes:

[0069] S3, control the unloading assembly to unload the separated combination 12, and control the loading assembly to load the new piece to be coated 30 onto the material cart 50, and finally control the rotary line to drive the material cart 50 to drive the new piece to be coated 30 to combine with the soft film 11 to form a new combination 12.

[0070] The present application sets up a material cart 50 to transport the workpiece 30 to be coated, and sets up a cutting structure 52 on the material cart 50. After the soft film 11 and the workpiece 30 to be coated are compounded on the material cart 50 under the high-temperature extrusion of the hot pressing roller 20 to form a combination 12, the material cart 50 drives the combination 12 to continue moving. At this time, the cutting structure 52 cuts the soft film 11 between two adjacent combinations 12 to separate them. Since the cutting structure 52 is set on the material cart 50, in the feeding direction of the material cart 50, the material cart 50, the soft film 11 and the cutting structure 52 are relatively stationary, avoiding the need to stop feeding for cutting and separation, thereby solving the problem of the hot pressing roller 20 damaging the soft film 11 and the reduction of production capacity due to stopping feeding, thereby reducing production costs and improving production efficiency.

[0071] The present application also provides a control method for a film pressing mechanism, by controlling the film supply structure 10 and each material cart 50 to transport the soft film 11 and the workpiece to be coated 30 respectively along the second horizontal direction. Under the high temperature of the hot pressing roller 20 and the mutual extrusion with the material cart 50, the soft film 11 and the workpiece to be coated 30 are squeezed to form a combination 12, and the cutting structure 52 on the material cart 50 is controlled to cut the soft film 11 between two adjacent material carts 50 / workpieces to be coated 30, thereby solving the problem of needing to stop feeding to cut the soft film 11, avoiding damage to the combination 12 due to the high temperature of the hot pressing roller 20, reducing production costs, and improving production efficiency.

[0072] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
