Description

Film sticking module and film sticking machine

Technical Field

The application relates to a film sticking module and a film sticking machine.

Background

Solar cell modules (i.e., photovoltaic modules) typically include a glass layer, an EVA encapsulant layer, a silicon wafer, and a solar cell backsheet/glass. Unused areas within the assembly can result in wasted light sources. To reduce light source waste, retroreflective sheeting is typically provided in these areas. In order to provide a reflective film, it is known in the art to use a laminator that conveys a reflective film strip to its film attachment assembly for attachment. Each laminator typically includes a plurality of laminator devices, for example, disposed side-by-side on a cross beam of the laminator frame.

In practice, the panel of the photovoltaic module needs to be attached with a plurality of, for example, 5, equally spaced light reflecting films along its width direction, and a plurality of, for example, 24, equally spaced light reflecting films along its length direction, with a light reflecting film pitch in the length direction set to, for example, 90mm.

In the prior art, a plurality of light reflecting films in a length direction are generally attached in at least two devices due to the limitation of an installation space. Taking attaching 24 reflective films with a spacing of 90mm as an example, two sequentially arranged devices are generally adopted to respectively attach 12 reflective films with a spacing of 180mm, and the positions of the two device adhesive films are staggered by 90mm along the length direction.

In order to increase the efficiency of the film application, it is desirable to integrate a plurality of, for example, 24 film application devices in one apparatus, which 24 film application devices are arranged side by side on the transverse beam and form the film application module of the film application machine, the distance between adjacent film application devices being 90mm. The film sticking device is removed, the distance between the areas for manually placing the film strips by an operator is only about 50mm or less when the film strips are replaced, and therefore the difficulty of manually replacing the film is increased or even the film cannot be replaced.

Disclosure of Invention

It is therefore an object of the present application to provide a film-sticking module and a film-sticking machine which at least partly solve the problems of the prior art.

According to a first aspect of the present application there is provided a film laminating module comprising a film laminating device comprising a support extending in a vertical direction and a holding portion provided with at least one guide wheel for guiding a film strip to be laminated, wherein the holding portion is movable from a first working position for a film laminating operation to a second working position above the first working position. In this way, the operator can, when a film web on a certain film laminating device needs to be replaced, individually move the film laminating device upwards into a second working position in which there is sufficient working space on the side of the holding part and complete the replacement and film threading operation of the film web.

One of the advantages of the film laminating module according to the application is that more film laminating devices can be arranged side by side on one film laminating machine without affecting the film changing operation.

According to some embodiments of the present application, a rotational connection is provided on a first side of the support facing the holding portion, the holding portion being pivotably connected with the rotational connection so as to be pivotable from the first working position to the second working position. According to some embodiments of the present application, the swivel connection is configured in a U-shape and has two parallel extending cantilever portions, between which a recess for receiving the holding portion is provided. According to some embodiments of the present application, the holding portion is provided with a first through hole, the two cantilever portions are respectively provided with a second through hole corresponding to the first through hole, and the holding portion is pivotally supported on the rotation connecting portion by a rotation shaft passing through the first through hole and the second through hole. By means of the pivoting movement described above, a switching of the holding part from the first operating position to the second operating position is achieved with a simple construction. Of course, the implementation form of the pivoting is not limited thereto, and a person skilled in the art may select a suitable pivoting structure according to the actual situation.

As an alternative implementation of the above-described pivot structure, a guide rail extending in the vertical direction is provided on a first side of the support facing the holding portion, a second slide member is provided on the guide rail, which is slidable relative thereto, and the holding portion is rigidly connected to the second slide member and is thereby slidable along the guide rail from the first working position to the second working position with the second slide member. According to some embodiments of the application, a sliding drive is provided on the support, which sliding drive is capable of driving the second slider via its actuating element to slide along the guide rail. The advantage of the above-described construction of the vertical guide rail is that an automated drive can be realized in a simple manner, so that the holding part automatically moves from the first operating position into the second operating position and automatically returns.

According to some embodiments of the present application, a first latching element is provided on the holding part and a first locking mechanism is provided on the carrier, which locking mechanism is capable of locking the holding part in the first operating position by means of a co-action with the first latching element. By means of the first latching element and the first locking mechanism described above, the holding part can be held fixedly in the first operating position, so that accuracy and reliability are ensured during the film-applying operation.

According to some embodiments of the present application, a second latching element is provided on the holding part and a second locking mechanism is provided on the carrier, which second locking mechanism is capable of locking the holding part in the second operating position by means of a co-action with the second latching element. By means of the second latching element and the second locking mechanism, the holding part can be held fixedly in the second working position, so that the film changing operation by an operator is facilitated.

According to some embodiments of the present application, the first latching element extends through an aperture in the mount from a first side of the mount facing the retaining portion to a second side of the mount remote from the retaining portion and protruding beyond the second side. Preferably, the lower side of the first latching element has a recess and the first locking mechanism has a first slider provided with a projection which is positively engaged with the recess. The advantage of this embodiment is that it does not require a space for the first side of the support, i.e. the side facing the holder, so that the construction of the film-coating device can be made more compact.

According to some embodiments of the present application, the first locking mechanism further has a driving member capable of driving the first slider to move toward and away from the first latch element, thereby achieving locking and unlocking with the first latch element. Thereby, locking and unlocking of the holding part in the first working position can be automatically achieved.

According to some embodiments of the application, the second locking mechanism is configured as a ball clasp and the second catch element is configured as a catch that is form-fit with the ball clasp. Since the film changing operation requires relatively low demands on the position stability and accuracy of the holding portion, the locking and unlocking in the second working position can be performed using the simple snap-in structure described above, but it is of course also possible to use a structure like the first snap-in element and the first locking mechanism.

According to some embodiments of the present application, the holding portion includes a base plate having a first cantilever portion and a second cantilever portion extending upward at a side portion, a gap portion is formed between the first cantilever portion and the second cantilever portion, and a guide wheel mounting plate for mounting the at least one guide wheel is further provided on the base plate, the guide wheel mounting plate covering the gap portion. This design of the guide wheel mounting plate separately from the base plate allows for more flexibility in mounting the guide wheel, etc., as the guide wheel mounting plate may be integrally removed from the base plate.

According to some embodiments of the present application, a guide groove is provided below the substrate, and the film sticking device includes a feeding device, and an output end of the guide groove is adjacent to an input end of the feeding device.

According to some embodiments of the application, the holding portion comprises a mounting plate, one side of the mounting plate being connected with a pinch roller device and the other side of the mounting plate being connected with a shearing device. This structure makes it possible to utilize the lateral space of the film sticking device to the maximum extent, so that it is arranged as compactly as possible.

According to some embodiments of the application, the film sticking device comprises a blowing device arranged below the holding part, and the blowing device is fixedly connected with the support. In the prior art, the blower is directly fixedly connected with the holding part, and if the holding part is lifted upwards, the blower is lifted up, so that an operator can be scalded, and the blower is arranged below the holding part and is fixedly connected with the support, so that the situation can be prevented.

According to some embodiments of the present application, a handle is fixedly connected to the mounting plate of the holding portion. By means of the handle, the holding portion can be pivoted upward or slid upward conveniently.

According to some embodiments of the present application, a plurality of film attachment devices are arranged side by side on a film attachment module, and the film attachment module is provided with a control unit, which is configured such that when one of the film attachment devices of the film attachment module is in the second operating position, the film attachment device adjacent to the film attachment device is locked in the first operating position. Preferably, the film-sticking module comprises at least one position sensor for detecting the working position of each film-sticking device. By means of the control unit, it is ensured that a film sticking device is not affected by an adjacent film sticking device when a film changing operation is performed by the film sticking device.

According to a second aspect of the present application there is provided a laminator comprising a laminator module according to the present application.

According to some embodiments of the present application, a plurality of film laminating devices are arranged side by side on a cross beam of the film laminating machine, each of the plurality of film laminating devices has a cartridge for storing and conveying a film strip, and the cartridges of two adjacent film laminating devices of the plurality of film laminating devices are arranged in a staggered manner in height. By arranging the cartridges with larger transverse dimensions in a staggered manner in height, the transverse installation space can be further saved, so that more film pasting devices can be arranged side by side under the condition of the same transverse installation space.

According to some embodiments of the present application, the laminator is used to laminate panels of photovoltaic modules.

Detailed Description

Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 shows a schematic view of a laminator 100 according to the present application. As can be seen in fig. 1, the laminator 100 comprises a housing 10, a frame 20, an operating panel 30 with a display, a platform module 40 comprising at least one lamination platform 41, and a lamination module 50 comprising at least one lamination device 51.

Fig. 2 shows a schematic view of the laminator 100 with the internal structure of the housing 10 omitted. It can be seen that a plurality of film attachment devices 51 arranged side by side in the cross-machine direction are fixed to the cross-beam of the frame 20 and thus form the film attachment module 50 of the film attachment machine. In the film laminating operation, the bottom of the film laminating device 51, that is, the position of the film tape output is slightly higher than the upper surface of the film laminating stage 41 in the vertical direction, and the film laminating stage 41 and the film laminating device 51 are movable relative to each other in the longitudinal direction of the machine so as to perform the film laminating operation.

Fig. 3 shows a schematic view of a film sticking apparatus 51 of the film sticking machine 100. As can be seen in fig. 3, the film laminating apparatus 51 comprises a stand 519 extending in a vertical direction, the stand 519 being slidably connected with a cross beam of the frame 20 of the film laminating machine for adjusting the lateral position thereof. Here, the stand 519 is configured as an elongated plate-like member extending in a vertical direction, but it should be understood that it may be configured in other suitable shapes and configurations. Above the stand 519 is arranged a material rack 518, which in this embodiment is connected to the stand 519, however it is also conceivable to form the material rack as one piece with the stand, i.e. the material rack 518 is part of the stand 519. One side of the frame 518 is provided with a cartridge 510 for storing and supplying the film strip 52, and the film strip 52 is wound on the cartridge 510 and can be transported from the cartridge 510 to the next working position via at least one (here three) guide rollers 511. The side of the frame 518 opposite the cartridge 510 is provided with a discharge drive 517, such as an electric motor, the discharge drive 517 being capable of driving the cartridge in rotation to transport the film web. Here, the film tape 52 has a first surface provided with no adhesive and a second surface provided with an adhesive.

In the dashed box below fig. 3 is a film attachment assembly 1 of a film attachment device 51 according to the present application, said film attachment assembly comprising a holding part 11, said holding part 11 comprising a base plate 110, the side edges of which are connected to said stand 519. In this embodiment, the base plate 110 has two first and second cantilever portions 112 and 113 extending in side portions upward so as to form a void portion therebetween, which extends to the upper side of the base plate 110 so that the base plate is open to the upper side and has a U-shape as a whole, wherein the first cantilever portion 112 is distant from the support 519 side with respect to the second cantilever portion 113. Referring to fig. 4, an input guide wheel bracket 114 is provided on the first cantilever portion 112, which extends upward beyond the upper end portion of the first cantilever portion 112, and a first guide wheel 115 is provided at the upper end of the guide wheel bracket 114, from which first guide wheel 115 the film tape 52 guided via a guide roller 511 enters the film sticking module 1. A guide wheel mounting plate 111 is fixedly connected to the base plate 110, and as can be seen with reference to fig. 5, a plurality of second guide wheels 116, in this embodiment 4 second guide wheels, are arranged on the guide wheel mounting plate, guide grooves 117 are formed on the base plate below the lowermost second guide wheels 116, and a film strip guided by the second guide wheels passes through the guide grooves 117 to enter the next working position.

It can also be seen from fig. 3 that a blowing device 12 is arranged below the holding part 11, that a pinch roller device 13 is arranged in front of the blowing device, that the sides of the pinch roller device are provided with a shearing device 14 according to the application, and that in addition a part of a feeding device 15 is visible. Specific configurations of the above-described blowing device, pinch roller device, shearing device, and feeding device will be described later.

Fig. 4 and 5 show perspective views of the construction of the film attachment assembly 1 from different angles, wherein the blower device 12 and other parts of the film attachment device 51, such as the support and the rack, the cartridge, etc., are not shown for clarity. Fig. 4 shows a first side of the film package 1, on which side the feeding device 15 is fixed by means of a connection mechanism such as a bolt. Fig. 5 shows a second side of the film assembly on which the second guide wheel 116 described above is provided. As can be seen in fig. 4 and 5, the feeding device 15 comprises a clamping mechanism 151, a feeding mechanism 152, an input 153 and an output 154. In the initial position, input 153 is adjacent to the output of guide slot 117, and output 154 is spaced from puck 131. As can also be seen from fig. 4, the holder 11 further comprises a mounting plate 118 fixedly connected to the edge of the base plate 110 on the side facing away from the abutment 519, and on a first side of said mounting plate 118 (i.e. on the side facing the viewer in fig. 4) a shearing device 14 according to the present application is connected. While, as can be seen in fig. 5, the puck assembly 13 is attached to a second side of the mounting plate 118 opposite the first side. Of course, it is also possible that the holding part 11 is not provided with the mounting plate, but the pinch roller device 13 and the shearing device 14 are directly fixed to both sides of the base plate 110, or that the mounting plate 118 may be constructed integrally with the base plate 110, i.e. the mounting plate 118 is constructed as a part of the base plate 110.

An exemplary workflow of the film sticking assembly 1 is as follows, first the pinch roller 131 of the pinch roller device 13 is lifted upwards, the clamping mechanism 151 of the feeding device 15 clamps the film strip 52, and the feeding mechanism 152 drives the film strip forward in the feeding direction until the end of the film strip is sent below the pinch roller 131, the pinch roller mechanism drives the pinch roller 131 to press the film strip onto the object to be stuck, such as a panel of a photovoltaic assembly, the clamping mechanism 151 unclamps the film strip and the feeding mechanism 152 returns to the initial position. After that, the film sticking module 1 and the panel of the photovoltaic module are relatively displaced, and in the process, the blowing device 12 continuously blows hot air to the lower side of the film strip, so that the adhesive on the second surface of the film strip 52 provided with the adhesive (for example, hot melt adhesive) melts, thereby completing the first stage of film sticking to the panel. After the first stage is completed, the clamping mechanism 151 clamps the film strip again, and then the cutting device 14 cuts the film strip, and a small piece of film strip is still located between the lower part of the pressing wheel 131 and the cutting part, so that the panel is further displaced relative to the film pasting component 11, and the small piece of film strip is further pasted on, for example, an edge part of the panel.

In the case where the film tape 52 for film attachment is exhausted, it is necessary to manually change the film by an operator who winds the film tape to be changed around the cartridge 510 and wears the end portion thereof to the vicinity of the output end of the feeding mechanism via the plurality of guide rollers 511, the first guide wheel 115, the second guide wheel 116, and the guide groove 117, which is also called film-wearing. As can be seen from fig. 3 to 5, in order to perform the film threading operation, a sufficient operation space needs to be left on the side of the holding portion 11 provided with the first guide wheel 115, the second guide wheel 116, and the guide groove 117, particularly on the side provided with the guide wheels and the guide groove. However, in the case where the shearing device 14, the pressing wheel device 13, and the feeding device 15 are required to be disposed on the left and right sides of the holding portion 11, a considerable lateral space, that is, a lateral space is required even if the above-described devices are disposed on the holding portion 11 as compactly as possible. On the other hand, the practical need to provide as many film laminating apparatuses as possible on one film laminating machine results in a very limited lateral space between the respective film laminating apparatuses, thereby making it difficult to perform the film threading operation.

To solve this problem, the inventors of the present application conceived to utilize the space above the film-sticking module 1. Specifically, the holding portion 11 of the film sticking module 1 of the film sticking apparatus 51 provided with the first guide wheel 115, the second guide wheel 116, and the guide groove 117 is allowed to move to the second working position above the first working position with respect to the first working position at the bottom of the stand 519 at the time of film sticking operation. Thus, when a film change is required in a certain film laminating apparatus, the whole holding portion 11 can be moved to the second working position, and in the second working position, a sufficient space exists on the side portion of the holding portion 11 for the film penetrating operation.

Fig. 6 and 7 show, respectively, from different angles, a schematic view of a film attachment device 51 of a film attachment module 50 according to a first embodiment of the present application, wherein the film attachment device 51 is in a first operating position, parts of which have been omitted for a clearer illustration. It can be seen that in the first operating position for the film-bonding operation, the base plate 110 of the holding portion 11 is disposed near the bottom of the stand 519, above the blowing device 12 and spaced from the blowing device 12 by a distance. To ensure the film-applying accuracy, in the first operating position the holding part 11 should be fixedly connected to the carrier 519, for which purpose, as shown in fig. 7, in this embodiment the side of the base plate 110 of the holding part 11 adjoining the carrier 519 is provided with a first latching element 1101, and on the carrier 519 a first locking mechanism 520 is provided which cooperates with the first latching element 1101, the first locking mechanism 520 being able to lock the holding part 11 in the first operating position by cooperation with the first latching element 1101.

Fig. 8 shows a partial detail of the first latching element 1101 in fig. 7. In this embodiment, the first latching element 1101 is formed as a projection which extends through a hole 5191 in the abutment 519 from a first side of the abutment 519 adjacent the holding part 11 to a second side thereof remote from the holding part 11 and protrudes beyond the second side. As can be seen from fig. 7 and 8, the first locking element 1101 has a recess 1101a on its underside, and the first locking mechanism 520 has a first slider 5201, which first slider 5201 is provided with a projection 5201a which is positively engaged with the recess 1101 a. The first locking mechanism 520 also has a driver 5202, e.g. a cylinder arrangement, an actuating element, e.g. a piston rod, of the driver 5202 being rigidly connected to the first slider 5201 for driving the first slider towards and away from the first catch element 1101 for locking and unlocking the first catch element. While one embodiment of the first locking element 1101 and the first locking mechanism 520 is described herein, other embodiments are also contemplated, for example, the upper side of the first locking element 1101 may have a groove 1101a instead of the lower side, and the first locking mechanism 520 may be correspondingly disposed above the groove, or a driving member of the first locking mechanism may be configured as a linear screw motor, etc., and various other suitable locking and unlocking schemes will be apparent to those skilled in the art and will not be repeated herein.

As can be seen from fig. 6, a swivel connection 5192 is provided on the side of the abutment 519 facing the holding part 11, to which swivel connection the upper end of the second cantilever 113 of the base plate is pivotably connected. Specifically, in this embodiment, the rotary connection is configured in a U-shape and has two parallel-extending cantilever portions, between which a recess for receiving the connection portion of the holding portion 11 is provided, and two through holes corresponding in position are provided on the two cantilever portions, through holes corresponding in position to the two through holes are provided on the upper end portion of the second cantilever 113 of this base plate 110 of the holding portion 11, and the rotary shaft 5193 passes through the three through holes, so that the holding portion 11 can be pivotally supported with respect to the rotary connection 5192 or with respect to the stand 519 by means of the rotary shaft 5193, whereby the holding portion 11 can be pivoted to the second operating position and pivoted from the second operating position back to the first operating position. Further, as can be seen in fig. 6, a handle 119 is fixedly attached to the mounting plate 118 to facilitate the operator's overall upward pivoting of the holding portion 11 by grasping the handle 119. Other pivotal connections are also contemplated and will not be described in detail herein.

It can furthermore be seen from fig. 6 that the blower 12 located below the holding part 11 is fixedly connected to the abutment 519 instead of to the holding part 11 as in the prior art, whereby the blower 12 is not lifted and the risk of scalding the person is not caused when the holding part 11 is moved from the first to the second operating position.

Fig. 9 shows a schematic side view of the film attachment device 51 in a second working position, in which it is seen that the holding part 11 is pivoted upwards relative to the first working position shown in fig. 6 to 8, to a second working position, in which case there is sufficient operating space on the side of the holding part for film penetration. As can also be seen in connection with fig. 6, a second latching element 1102 is provided on the upper side of the holding part 11 and a second locking mechanism 5194 is provided in the corresponding position of the abutment 519, the second latching element 1102 being able to be snapped into engagement with the second locking mechanism 5194 when the holding part 11 is pivoted upwards into the second operating position. In this embodiment, the second locking mechanism 5194 is configured as a ball button and the second catch element is configured as a catch that mates with the shape of the ball button. The specific design of the second locking element and the second locking mechanism is not limited to the form of the catch described above, but can be varied as the case may be, for example, the second locking element and the second locking mechanism can also be designed similarly to the first locking element and the first locking mechanism for the first operating position.

Fig. 10 shows a film laminating device 51 of a film laminating module according to a second embodiment of the present application, wherein most of the structure of the film laminating device is the same as in the first embodiment, except mainly how the switching between the first operating position and the second operating position is achieved. As can be seen from fig. 10, the support 519 is provided on its side adjacent to the holding portion 11 with a guide rail 5195 extending in the vertical direction, on which a second slide 5196 is provided, which is slidable relative to the guide rail, the holding portion 11 being rigidly connected to the second slide 5196, preferably the second cantilever portion 113 of the holding portion 11 being rigidly connected to the second slide 5196. Furthermore, a sliding drive 5197 is provided, which is optionally also provided on the carrier 519. In this embodiment, the sliding drive 5197 is configured as a cylinder, for example a pen cylinder, which via its actuating element drives the second slider 5196 along the guide rail 5195, so that the holding part 11 can be brought from the first operating position into the second operating position and back from the second operating position into the first operating position. Of course, the driving unit may be configured as another suitable driving device such as a screw motor. In this second embodiment, corresponding latching elements and locking mechanisms are likewise provided, which are not described in detail here.

According to some embodiments of the present application, the film-applying module 50 is further provided with a control unit, not shown in the figures, which is configured such that when one of the film-applying devices of the film-applying module is in the second working position, the film-applying device adjacent to this film-applying device is locked in the first working position, for example by the driver 5202 controlling the first locking mechanism 520. Preferably, the film-sticking module comprises at least one position sensor for detecting the working position of each film-sticking device. By the control unit, the film changing operation of a certain film sticking device can be ensured not to be influenced by the adjacent film sticking device.

By the above-described solution, the laminator 100 according to the present application can realize arranging a plurality of laminator devices 51 side by side compactly to realize more laminator stations on one laminator. For example, referring to fig. 2, it can be seen that a plurality of film laminating devices 51 are arranged side by side on a cross beam of the film laminating machine, and in order to further increase the utilization rate of the lateral space, the cartridges 510 of two adjacent film laminating devices 51 are arranged in a staggered manner in height, so that more film laminating devices 51 can be arranged with the same lateral space.

The technical solutions of the present application are explained above in terms of exemplary preferred embodiments. It should be noted that the above embodiments are merely for illustrating the technical solutions of the present application, and are not limiting; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features can be replaced with equivalents; such modifications and substitutions do not depart from the spirit of the embodiments, and are intended to be included within the scope of the claims and description.
