Technical Field

The application relates to the technical field of automation equipment, in particular to film processing equipment.

Background

Currently, many industrial and consumer electronic devices and electronic products are often provided with a thin film on their surface for various purposes, for example, as a protective film or a thin film for other purposes.

For example, the housing of a floor sweeper or a floor washer is made of ABS (Acrylonitrile Butadiene Styrene) material to have a high-brightness surface, but the ABS material is soft and therefore easily scratched.

In the prior art, a protective film is usually adhered manually, and the operation process comprises the following steps:

firstly, pulling out a protective film from a protective film drum wound into a drum;

secondly, because the top surface of the sweeper or the scrubber is usually provided with a laser emitting module protective cover (LDS-damper), a round hole needs to be cut in the protective film for avoiding;

thirdly, cutting off the protective film with a certain length; and

and fourthly, attaching the cut protective film to the surface of the product.

However, the above-mentioned manual protective film pasting method has the problems of complicated steps, low efficiency, easy occurrence of the problems of bumping the surface of the equipment during the operation process, or uneven pasting of the protective film, etc., and the failure rate of pasting the protective film is high, sometimes even about 10%, which causes great waste of manpower and material resources.

Detailed Description

For a better understanding of the technical solutions and advantages of the present application, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. The specific embodiments described herein are merely illustrative of the present application and are not intended to be limiting of the present application. In addition, the technical features mentioned in the embodiments of the present application described below may be combined and used unless they conflict with each other, thereby constituting other embodiments within the scope of the present application.

The following description provides many different embodiments or examples for implementing different structures of the application. In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

Fig. 1 and 2 show perspective views of a thin film processing apparatus according to an embodiment of the present application, viewed from different angles. In fig. 2, a side plate of the device of fig. 1 and other parts are hidden. As shown in fig. 1 and 2, the thin film processing apparatus 100 may include a transfer assembly 110, a cutting assembly 120, and a film cutting assembly 130. The transfer assembly 110 for transferring the film 200 to be processed may include a plurality of tension rollers 111 to tension the film 200 and guide the film 200 during the transfer. It is to be understood that the arrangement and number of the tension rollers 111 shown in the drawings are merely exemplary and do not constitute a limitation of the scope of the present application.

The cutting assembly 120 is disposed adjacent to the conveying assembly 110 for cutting a predetermined shape at a predetermined position of the film 200. According to one embodiment, the predetermined shape may be a specific shape (e.g., a circle, an ellipse, a square, a rectangle, etc.) located at a predetermined position, so that the raised features on the surface of the device to be filmed can be avoided when the film is applied, and the number and the position of the specific shape can be flexibly adjusted according to needs.

The film cutting assembly 130 is located downstream of the cutting assembly 120 with respect to the conveying direction of the film 200, and the film cutting assembly 130 serves to cut the film 200, which has been cut into a predetermined shape at a predetermined position. That is, after the cutting member 120 has cut a predetermined shape at a predetermined position, the film in which the predetermined shape has been cut is cut.

Therefore, the film cutting device can replace a manual film cutting mode, the operation efficiency is improved, and for products with different sizes, as long as the tensioning roller is large enough, films with large enough sizes can be selected for cutting and cutting, so that the adaptability of the device is improved. In addition, the device can cut a notch with a preset shape at a preset position of the film before cutting the film, thereby completing two operations of cutting and film cutting under one device and improving the efficiency.

As for the shape that cuts out in predetermined position, this application can adjust according to actual need. For example, as mentioned above, the predetermined shape may be a specific shape located at a predetermined position, which enables adaptation to requirements such as surface filming on a sweeper or scrubber. Figure 3 shows a schematic view of a sweeper or scrubber. As shown in the perspective view of the sweeper or scrubber 300 shown on the left side of figure 3 and in the side view of the sweeper or scrubber 300 shown on the right side of figure 3, the sweeper or scrubber 300 may have a raised laser emitting module protective cover (LDS-bulb) 310 on its upper surface. The protective cover 310 has the shape of an eccentric circle (i.e., a small circle deviating from the center of a large circle of the entire upper surface) on the entire upper surface. Therefore, cutting the film 200 into an eccentric circle before cutting the film will make the cut film leave the protective cover 310 and can be directly used for subsequent film attachment.

FIG. 4 illustrates a perspective view of a cutting assembly according to one embodiment of the present application. As shown in fig. 4, the cutting assembly 120 may include a support structure 121, a fixed mounting plate 122, and a movable cutting portion 123. The support structure 121 may be disposed parallel to the traveling direction of the film 200 for supporting the film 200 during cutting. The supporting structure 121 has a hollow structure 121A corresponding to a predetermined shape at a position corresponding to a predetermined position of the thin film 200, and the hollow structure 121A may be disposed through the supporting structure or may not be disposed through the supporting structure. The shape of the hollow structure can be the same as or different from the preset shape.

The fixed mounting plate 122 and the support structure 121 are mounted opposite to each other on both sides of the membrane 200. The movable cutting part 123 is installed above the supporting structure 121, for example, on the fixed mounting plate 122, and is used for pushing a predetermined position of the film 200 into the hollow structure 121A during cutting, so as to cut a predetermined shape at the predetermined position of the film 200. Therefore, the cutting assembly can be used for cutting a preset shape at a preset position of the film.

FIG. 5 illustrates a perspective view of a moving cut-out according to one embodiment of the present application. As shown in fig. 5, the moving cutting part 123 may include an upper cutter die 123A, a first driving mechanism 123B, and a guide rod 123C. The upper cutting die 123A has the predetermined shape and enters or exits the hollow structure 121A under the control of the driving mechanism. According to one embodiment, the upper cutting die 123A may have or be coupled with a heating element (not shown) to enable thermal cutting of the film 200. It is understood that the thermal cutting method described above is only an example, and other cutting methods may be used in practice, and the present invention is not limited thereto.

The first driving mechanism 123B has a fixed housing 123B1 and a driving end 123B2, the fixed housing 123B1 is mounted on the fixed mounting plate 122, and the driving end 123B2 is fixedly connected to the upper cutting die 123A to drive the upper cutting die 123A to advance or retract in the direction of the film 200. One end of the guide rod 123C passes through the through hole of the fixed mounting plate 122, and the other end is fixedly connected to the upper cutting die 123A, thereby guiding the movement of the upper cutting die 123A.

Therefore, the film 200 can be pushed into the hollow-out structures 121A of the supporting structure 121 at the predetermined positions by the upper cutting die 123A, and since the upper cutting die 123A and the hollow-out structures 121A have the same predetermined shape, the same predetermined shape can be cut out at the predetermined positions of the film 200 by thermal cutting, mechanical cutting, or the like.

Preferably, the upper cutting die 123A and/or the moving cutting part 123 are modular in design and replaceable. Specifically, the upper cutting die 123A can be independently replaced to adapt to different cutting purposes, so that different shapes can be cut; or the movable cutting part 123 is replaced, and different movable cutting parts have upper cutting dies with different models; or to replace the upper blade die 123A and move the cutting part 123 except the upper blade die 123A at the same time. In summary, the above design aims to cut different predetermined shapes, thereby making the apparatus of the present invention suitable for different film application purposes. In one embodiment, after a new upper cutting die is used, the supporting structure 121 can be replaced correspondingly, and the replaced supporting structure has a hollow structure 121A matched with the upper cutting die 123A; the matching means that the hollow-out structure 121A has the same shape as or different from the predetermined shape, but the hollow-out structure 121A can accommodate the upper cutting die 123A. Optionally, the supporting structure 121 may not be replaced in a part of usage scenarios, and at this time, only the size of the hollow structure 121A on the supporting structure 121 needs to be enough to accommodate the upper cutting die 123A. Preferably, when the shape of the hollow structure 121A is the same as the upper cutting die 123A and the size is slightly larger than the upper cutting die 123A, a better cutting effect can be obtained under a thermal cutting or other cutting manner.

Preferably, the mounting position of the upper cutting die 123A is adjustable relative to the movable cutting portion 123, or the position of the movable cutting portion 123 is adjustable relative to the fixed mounting plate 122, or the mounting position of the upper cutting die 123A is adjustable relative to the movable cutting portion 123, and the position of the movable cutting portion 123 is adjustable relative to the fixed mounting plate 122. In practice, the position of the upper cutting die 123A relative to the film 200 is adjustable, which is important when assembly errors cause the cutting position to be unexpected, or when the cutting position on the film 200 of the predetermined shape needs to be adjusted. Specifically, this can be achieved by adjusting the positional relationship between the upper blade die 123A and the movable cutting portion 123, or adjusting the position of the movable cutting portion 123 relative to the fixed mounting plate 122, or adjusting both the position of the upper blade die 123A relative to the movable cutting portion 123 and the position of the movable cutting portion 123 relative to the fixed mounting plate 122.

FIG. 6 shows a perspective view of a thin film processing apparatus according to one embodiment of the present application. The film drawing assembly 140 is shown in part a of fig. 6. As shown in fig. 6, the film processing apparatus 100 may further include a film drawing assembly 140 in addition to the conveying assembly 110, the cutting assembly 120, and the film cutting assembly 130. The film pulling assembly 140 is located downstream of the film cutting assembly 130 (which is blocked by side plates and other structures of the apparatus 100 in fig. 6) with respect to the transport direction of the film 200, for pulling the ends of the film that have been cut into a predetermined shape at predetermined positions.

Fig. 7 and 8 respectively show perspective views of a film drawing assembly from different angles according to an embodiment of the present application. Fig. 7 is a perspective view of fig. 6 as viewed from a lower portion thereof, and fig. 8 is a perspective view of fig. 6 as viewed from an upper portion thereof. As shown in fig. 7 and 8, the film drawing assembly 140 may include a guide rail 141, a slider 142, a movable holder 143, a lower clamp block 144, an upper clamp block 145, and a second driving mechanism 146.

The guide rails 141 are positioned at both sides of the film 200, and the slider 142 is slidably disposed on the guide rails 141. Both ends of the moving holder 143 are fixed to the sliders 142, respectively, so that the moving holder 143 can slide along the guide rail 141. The movable holding frame 143 is used to move the upper and lower clamping blocks 145 and 144 to pull the film 200 to the next station. The lower clamping block 144 is integrally formed with or fixedly attached to the movable clamping frame 143, and the upper clamping block 145 is disposed adjacent to the lower clamping block 144 for clamping the film 200 in cooperation with the lower clamping block 144. The second driving mechanism 146 has a fixed housing 146A and a driving end 146B, the fixed housing 146A is mounted on the movable holder 143, and the driving end 146B is fixedly connected to the upper clamping block 145 to drive the upper clamping block 145 to move toward or away from the lower clamping block 144, so as to clamp or release the film 200.

According to one embodiment, the drive end 146B of the second drive mechanism 146 may be fixedly coupled directly to the upper clamp block 145 or indirectly via a transfer block 147.

When the driving end 146B drives the upper clamping block 145 to move towards the lower clamping block 144, the upper clamping block 145 and the lower clamping block 144 gradually clamp the film 200; when the driving end 146B drives the upper clamping block 145 to move away from the lower clamping block 144, the upper clamping block 145 and the lower clamping block 144 gradually loosen the film 200.

Therefore, when the film 200 is conveyed to the film cutting assembly 130 by the conveying assembly 110 and the film cutting operation is completed, the film pulling assembly 140 can be controlled to move towards the film cutting assembly 130, and after the film 200 is positioned, the film pulling assembly 140 can clamp the end of the film 200 and move away from the film cutting assembly 130, so that the end of the film 200 is pulled out and tensioned.

Fig. 9 illustrates a perspective view of a slit film assembly according to an embodiment of the present application, as viewed from a lower portion of fig. 1. As shown in fig. 9, the film cutting assembly 130 may include a film support bar 131, a guide rail 132, and a cutter 133. The film supporting bars 131 are disposed perpendicular to the traveling direction of the film 200 so as to be able to support the film 200 that has been cut out in a predetermined shape at predetermined positions. The guide rail 132 is disposed parallel to the film support bar 131 and spaced apart from the film 200. The cutter 133 is slidably engaged with the guide rail 132 and is movable along the extending direction of the film supporting bar 131, and when the film 200 is stretched to a predetermined position, the cutter 133 is slidable along the guide rail 132 to cut the film 200.

According to one embodiment, tool 133 may be directly slidably engaged with rail 132, or may be slidably engaged with rail 132 via tool mount 134, and tool 133 may be mounted within tool mount 134.

At the moment when the film 200 is cut, the driving end 146B of the second driving mechanism 146 may drive the upper clamping block 145 to move away from the lower clamping block 144, thereby releasing the clamping effect on the film 200 and allowing the cut film to freely fall with the two ends thereof being free.

FIG. 10 illustrates the relative positions of the lower clamp blocks and the film support strip after the film has been stretched according to one embodiment of the present application (the film is not shown). FIG. 11 illustrates the relative positions of the clamp blocks and the film support bars at the instant of beginning stretching of the film according to one embodiment of the present application. As shown in fig. 10 and 11, the film supporting bar 131 and the lower clamping block 144 are located on the same horizontal plane, the film supporting bar 131 has a first tooth-shaped structure facing the lower clamping block 144, and the lower clamping block 144 has a second tooth-shaped structure facing the film supporting bar 131, so that when the film pulling assembly 140 moves to be adjacent to the film cutting assembly 130, the first tooth-shaped structure of the film supporting bar 131 and the second tooth-shaped structure of the lower clamping block 144 are in staggered engagement with each other. Since there will always be a portion of the membrane 200 on the upper surface of the membrane support bar 131, the mating of the two teeth will allow the lower clamp block 144 to be positioned on the underside of the membrane 200 when clamped. Preferably, in order to smoothly clamp the end of the thin film, the upper surface of the lower clamping block 144 may be slightly lower than the upper surface of the thin film supporting bar 131, or the upper surface of the tooth-shaped structure of the lower clamping block 144 may be slightly lower than the upper surface of the thin film supporting bar 131, or a chamfer or a fillet may be machined on the tooth-shaped structure of the lower clamping block 144 so that the tooth-shaped structure of the lower clamping block 144 is smoothly inserted into the bottom of the thin film supporting bar 131; it is to be understood that the above-described arrangements may also be used in appropriate combinations. When first used, the ends of the film 200 may be pulled manually or in other suitable manner onto the upper surfaces of the film support bars 131, and the film pulling operation may be subsequently performed automatically by the apparatus 100.

FIG. 12 illustrates a perspective view of a brush membrane assembly according to one embodiment of the present application. As shown in fig. 12, the thin film processing apparatus 100 may further include a brush film assembly 150 in addition to the transfer assembly 110, the cutting assembly 120, and the film cutting assembly 130. The brush film assembly 150 is located downstream of the film cutting assembly 130 with respect to the transport direction of the film 200, and is used to brush the cut film onto the surface of the apparatus 300 to be laminated. Thus, the entire process of cutting, slitting, and attaching can be achieved by the apparatus 100.

Specifically, the brush membrane assembly 150 may include a third driving mechanism 151, a mounting plate 152, a fourth driving mechanism 153, a brush 154, and a guide bar 155. The third driving mechanism 151 for driving the brush 154 to reciprocate along the surface to be filmed may have a stationary housing 151A and a driving end 151B, the stationary housing 151A being mounted on the housing of the apparatus 100. The end of the mounting plate 152 is fixedly connected to the driving end 151B of the third driving mechanism 151, directly or indirectly, so as to be movable in the traveling direction of the film 200 by the driving of the third driving mechanism 151. A fourth drive mechanism 153 for driving the brush 154 towards or away from the membrane 200 may have a stationary housing 153A and a drive end 153B, the stationary housing 153A of the fourth drive mechanism 153 being mounted on the mounting plate 152. The brush 154 may be directly or indirectly connected to the driving end 153B of the fourth driving mechanism 153 so as to be movable toward or away from the film 200 by the fourth driving mechanism 153. The guide rod 155 has one end passing through the through hole of the mounting plate 152 and the other end fixedly coupled to the brush 154, directly or indirectly, to guide the movement of the brush 154.

Therefore, the two driving mechanisms can drive the brush to move in the advancing direction of the film and the direction vertical to the surface of the film, so that when the cut film falls to the surface of the film sticking device, the brush can be used for completing the sticking operation. Therefore, the film pasting operation of the mechanical pressing equipment in the prior art can be avoided, and the risk that the surface of the film pasting device is embossed in the film pasting process due to the film pasting operation of the mechanical pressing equipment is higher, so that the brush is adopted for the film pasting operation in the application, and the point is avoided.

It is to be appreciated that one or more controllers may be utilized to control the operation of the third drive mechanism 151, the fourth drive mechanism 153, and the first drive mechanism 123B, the second drive mechanism 146 described above to effect the driving of the various components of the apparatus 100.

Fig. 13 shows a perspective view of a thin film processing apparatus according to another embodiment of the present application. As shown in fig. 13, the film processing apparatus 100 may further include a to-be-laminated device conveying assembly 160 in addition to the conveying assembly 110, the cutting assembly 120, and the film cutting assembly 130. The device to be laminated conveying assembly 160 is used for conveying the device to be laminated 300 to a laminating station for laminating.

Specifically, the device to be laminated conveying assembly 160 may include a guide rail 161, a carrying platform 162, and a sensor (not shown in the figure). The carrying platform 162 is used for carrying and conveying the device 300 to be film-pasted to the film-pasting station, and is in sliding fit with the guide rail 161, so that the device 300 to be film-pasted can slide along the guide rail 161 to be below the brush film assembly 150. The sensor is used for sensing a preset position below the membrane brushing assembly 150, and when the sensor detects that the device 300 to be laminated reaches the laminating station, the sensor triggers the thin film processing equipment 100 to start to operate.
