Description

Technical Field

[0001] The invention relates to the field of solar photovoltaic product processing, and in particular to a film preparation device and metal wire film processing equipment. Background Art

[0002] In the field of solar photovoltaic equipment manufacturing at home and abroad, one of the steps in the preparation of metal wire film is to cut the film strip into film sheets of standard size, and then move the film sheets and hot press them onto the metal wire. The film sheets are grasped and moved by a grasping mechanism, which provides the cut film sheets to the metal wire, then returns to grasp the film sheets and re-provides the film sheets to the metal wire. During this process, the grasping mechanism partially moves idle, resulting in a low overall efficiency in providing the film sheets and a slow speed in providing the film sheets, which in turn affects the processing efficiency of the metal wire film. Summary of the invention

[0003] Based on this, it is necessary to provide a film preparation device to address the above problems, improve the efficiency of supplying film sheets, and further improve the processing efficiency of metal wire films.

[0004] A film preparation device, comprising:

[0005] Control module;

[0006] A diaphragm supply mechanism, electrically connected to the control module, the diaphragm supply mechanism is used to process the diaphragm and transfer the diaphragm to a preset station;

[0007] At least two film supply mechanisms are provided, and each of the film supply mechanisms sequentially transmits the film to the preset station.

[0008] The above-mentioned film preparation device has more than two film supply mechanisms. When providing film to the preset station, the main control module controls multiple film supply mechanisms to transfer the film to the preset station in turn. After the preset station receives a film, the next film supply mechanism starts or has already transferred the film to the preset station. Multiple film supply mechanisms transfer the film to the preset station, which reduces the interval of conveying the film to the preset station, greatly improves the efficiency of film transmission, and thus improves the production efficiency of metal wire film.

[0009] In one embodiment, the film supply mechanism comprises:

[0010] Two film mechanisms, the film mechanisms comprising a film tape transmission and cutting assembly and a film stage, the film tape transmission and cutting assembly being electrically connected to the control module and used for cutting the film tape into films of a preset size and transmitting the films to the film stage;

[0011] The diaphragm grabbing mechanisms are the same in number as the diaphragm mechanisms, and each of the diaphragm grabbing mechanisms corresponds to a diaphragm stage of each of the diaphragm mechanisms, and the diaphragm grabbing mechanisms are electrically connected to the control module, and are used to grab the diaphragm on the diaphragm stage and release the diaphragm at a preset station;

[0012] The film supply mechanism comprises: a displacement member connected to the film grabbing mechanism, the displacement member is electrically connected to the control module and is used to drive the film grabbing mechanism to move between the film stage and the preset station; or

[0013] The film preparation device includes: a displacement mechanism, each of the film grabbing mechanisms is connected to the displacement mechanism, and the film grabbing mechanism is electrically connected to the control module, and is used to drive the film grabbing mechanism to move between the film stage and the preset station under the control of the control module; when a film grabbing mechanism leaves the preset station, at least another film grabbing mechanism moves toward the preset station.

[0014] By setting up at least two diaphragm mechanisms and diaphragm grabbing mechanisms, the control module controls the displacement mechanism to drive the two diaphragm grabbing mechanisms to move, so as to realize multi-line film supply. During the process of one diaphragm grabbing mechanism walking back to the diaphragm table empty, the other diaphragm grabbing mechanism transfers the diaphragm to the preset station, so that the time when the diaphragm grabbing mechanism walks empty is filled by the transmission of the other diaphragm grabbing mechanism, so that there is always a diaphragm grabbing mechanism in the film preparation device to transfer the diaphragm to the preset station, which greatly improves the efficiency of diaphragm transmission, that is, the efficiency of film preparation, thereby improving the production efficiency of metal wire film.

[0015] In one embodiment, the displacement mechanism includes: a lifting assembly and a transverse movement assembly, wherein the transverse movement assembly is used to drive the lifting assembly and the diaphragm grabbing mechanism to move between the diaphragm stage and the preset workstation, and the lifting assembly controls the diaphragm grabbing mechanism to move closer to or away from the diaphragm stage / preset workstation.

[0016] In one embodiment, the diaphragm mechanism and the diaphragm grabbing mechanism are each provided with two, and the two diaphragm stages are respectively provided on both sides of the preset station. In the process of one diaphragm grabbing mechanism walking back to the diaphragm stage empty, the other diaphragm grabbing mechanism transfers the diaphragm to the preset station, so that the time when the diaphragm grabbing mechanism walks empty is filled by the transmission of the other diaphragm grabbing mechanism, so that there is always a diaphragm grabbing mechanism in the film preparation device to transfer the diaphragm to the preset station, which greatly improves the efficiency of diaphragm transmission, that is, film preparation, thereby improving the production efficiency of metal wire film. Preferably, the two diaphragm stages are respectively provided on both sides of the preset station, and the distances between the two diaphragm stages and the preset station are equal, so that the time when one diaphragm grabbing mechanism walks back to the diaphragm stage empty is the same as the time when the other diaphragm grabbing mechanism transfers the diaphragm to the preset station, thereby maximizing the film preparation efficiency.

[0017] In one of the embodiments, the transverse movement assembly includes: a transverse movement track, a transverse movement member slidably arranged on the transverse movement track, and the lifting assembly and the diaphragm grabbing mechanism are arranged on the transverse movement member.

[0018] In one embodiment, the lifting components are equal in number to the film grabbing mechanisms and are connected one by one, and each lifting component is connected to the transverse member. When one film grabbing mechanism is located at a preset station, the other film grabbing mechanism is located at the film table, and the distance between the two film grabbing mechanisms is always the same, so one transverse member is provided.

[0019] In one embodiment, the number of the diaphragm mechanism and the diaphragm grabbing mechanism is greater than or equal to 3, and the moving track of the transverse moving assembly is annular, driving each of the lifting assemblies and the diaphragm grabbing mechanism to pass through the preset station in sequence. After the diaphragm grabbing mechanism provides the diaphragm to the preset station, in the process of grabbing the diaphragm, another diaphragm grabbing mechanism provides the diaphragm to the preset station, which greatly improves the film preparation efficiency.

[0020] In one embodiment, the film grabbing mechanism includes: a film suction table, a film suction member disposed on the film suction table and electrically connected to the control module, the film suction member providing the film suction table with negative pressure for adsorbing the film. When the film suction table is close to the film, the film can be sucked by the negative pressure of the film suction member, and the film is not easily damaged.

[0021] The present invention also provides a metal wire film processing device, comprising the above-mentioned film preparation device, wherein the preset station is provided with a thermal composite platform, and a plurality of metal wires are transmitted on the thermal composite platform. In the metal wire film processing device of this embodiment, since the film preparation device has a high film supply efficiency, the thermal composite efficiency and the overall processing efficiency of the metal wire film are also improved.

[0022] In one embodiment, the metal wire film processing equipment has multiple film preparation devices. The metal wire has at least two composite sides that are thermally composited with the film sheet, and each composite side is provided with at least one film preparation device. During the production process of the metal wire film, it is necessary to thermally composite the film sheet on both sides of the metal wire, and a film preparation device can only supply film on one side of the metal wire. Therefore, the metal wire film processing equipment in this embodiment has multiple film preparation devices. Two film preparation devices can be provided to supply film from both sides of the metal wire; four film preparation devices can also be provided, two by two on both sides of the metal wire, and two film sheets can be supplied to both sides of the metal wire at one time, thereby improving the transmission speed of the metal wire and further improving the processing efficiency of the metal wire film.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] The first embodiment of the present invention relates to a film preparation device, which is mainly used to provide a film sheet, and can be typically used on a metal wire film processing device to provide the film sheet to the metal wire during the metal wire film processing process.

[0031] like Figure 1As shown, the film preparation device in this embodiment includes: a control module (not shown in the figure), a film supply mechanism and a displacement mechanism 3, wherein the film supply mechanism includes: a film mechanism 1 and a film grabbing mechanism 2, the control module is a control chip, wherein the film mechanism 1 includes: a film tape transmission and cutting component 11 and a film stage 12. The film tape transmission and cutting component 11 is electrically connected to the main control module, cuts the film tape 4 into films of a specified size and transmits them to the film stage 12, and the transmission direction is shown by the arrow X in the figure, and the displacement mechanism 3 controls the film grabbing mechanism 2 to grab the film on the film stage 12 and move it to the specified position to complete the provision of the film.

[0032] The film tape transmission and cutting assembly 11 includes: a film tape transmission member 111, a cutting member 112 and a base 113, wherein the film tape transmission member 111 and the cutting member 112 are electrically connected to the control module and work under the control of the control module, and the base 113 is arranged on the ground to lift the film tape transmission member 111 to a certain height. The film tape transmission member 111 is a conveyor belt arranged on the base 113, and the film tape 4 is a strip-shaped film, and the length direction of the film tape 4 is consistent with the transmission direction of the conveyor belt, so that the film tape 4 is continuously transmitted on the film tape transmission member 111. The cutting piece 112 is arranged above the film tape transmission piece 111. The cutting piece 112 has a cutter. At regular intervals, after the film tape 4 moves a certain distance on the film tape transmission piece 111, the control module controls the film tape transmission piece 111 to suspend transmission. The cutting piece 112 cuts the film tape 4 by the cutter to form a film sheet. The size of the film sheet is suitable for use in the next station. After the film sheet is cut, the film tape transmission piece 111 continues to move and transmits the film sheet to the film sheet stage 12 at the tail end of the film tape transmission piece 111. The film sheet waits for the film sheet grabbing mechanism 2 on the film sheet stage 12. The table top of the film sheet stage 12 is comb-shaped, and the film sheet is laid on the comb-shaped table top. The comb-shaped table top can save the material and cost of the film sheet stage 12, and at the same time facilitate the film grabbing mechanism 2 to grab the film.

[0033] After the film grabbing mechanism 2 grabs the film, it moves the film from the film stage 12 to the preset station 5 under the drive of the displacement mechanism 3, completing the provision of the film once, wherein the preset station 5 can perform any operation on the film, such as collecting, thermally compounding and other processes. In this embodiment, the preset station 5 is a thermally compounding platform, and the thermally compounding platform is provided with a metal wire 6. The film grabbing mechanism 2 moves the grabbed film to the thermally compounding platform and then releases it, and thermally compounds the film with the metal wire 6. After the thermal compounding is completed, the film grabbing mechanism 2 returns to the film stage 12 under the drive of the displacement mechanism 3. At this time, there is a newly cut new film on the film stage 12. The film grabbing mechanism 2 grabs and moves the film to the preset station 5 again, and each time the film is moved, the film preparation is completed once. It is worth noting that during the process of the diaphragm grabbing mechanism 2 returning from the preset workstation 5 to the diaphragm stage 12, the diaphragm grabbing mechanism 2 moves empty. After transferring a diaphragm once, it is necessary to wait for the diaphragm grabbing mechanism 2 to move empty back to the diaphragm stage 12 before starting the next diaphragm grabbing and transferring, which makes the efficiency of providing diaphragms low.

[0034] In the film preparation device in this embodiment, Figure 2 As shown, there are at least two film supply mechanisms. In this embodiment, the number of film supply mechanisms is 2 for illustration without specific limitation. That is, the number of film mechanism 1 and film grabbing mechanism 2 are both 2. Figure 1 and Figure 2Both diaphragm mechanisms 1 have a film tape transmission and cutting component 11 and a diaphragm stage 12, that is, there are two diaphragm stages 12 to provide diaphragms for the preset workstation 5. Two diaphragm grabbing mechanisms 2 are also provided, corresponding to the two diaphragm stages 12 respectively. The two diaphragm grabbing mechanisms 2 are both connected to the displacement mechanism 3. The diaphragm grabbing mechanism 2 and the displacement mechanism 3 are both electrically connected to the control module. The control module controls the movement of the displacement mechanism 3 and the diaphragm grabbing mechanism 2 to grab / release the diaphragm. The displacement mechanism 3 drives the two diaphragm grabbing mechanisms 2 to move between the preset workstation 5 and the corresponding diaphragm stage 12, and the two diaphragm grabbing mechanisms 2 alternately enter the preset workstation 5. For the convenience of explanation, the two film grabbing mechanisms 2 in this embodiment are respectively the first film grabbing mechanism 21 and the second film grabbing mechanism 22. When the first film grabbing mechanism 21 is located at the preset station 5, the second film grabbing mechanism 22 is located on the corresponding film stage 12 to pick up the film; when the first film grabbing mechanism 21 returns to the film stage 12 to pick up the film, the second film grabbing mechanism 22 transports the film from the film stage 12 to the preset station 5. As can be seen from the above, the film preparation device in this embodiment realizes dual-line film supply by setting two film mechanisms 1 and film grabbing mechanisms 2. When one film grabbing mechanism 2 is empty and returns to the film stage 12, the other film grabbing mechanism 2 transfers the film to the preset station 5, so that the time when the film grabbing mechanism 2 is empty is filled by the transmission of the other film grabbing mechanism 2, so that there is always a film grabbing mechanism 2 in the film preparation device to transfer the film to the preset station 5, which greatly improves the efficiency of film transmission, that is, film preparation, thereby improving the production efficiency of metal wire film. It is worth noting that the two diaphragm stages 12 are respectively arranged on both sides of the preset workstation 5, and the distances between the two diaphragm stages 12 and the preset workstation 5 are equal, so that the time it takes for one diaphragm grabbing mechanism 2 to return to the diaphragm stage 12 empty is the same as the time it takes for another diaphragm grabbing mechanism 2 to transfer the diaphragm to the preset workstation 5, thereby maximizing the film preparation efficiency.

[0035] Among them, the diaphragm grasping mechanism 2 can grasp the diaphragm by claws, or absorb the diaphragm by negative pressure. As a preference, the diaphragm grasping mechanism 2 in this embodiment absorbs the diaphragm by negative pressure. The diaphragm grasping mechanism 2 includes: a film suction table 23, a film suction component 24 arranged on the film suction table 23 and electrically connected to the control module, a through hole is provided on the film suction table 23, and the film suction component 24 provides negative pressure for sucking the diaphragm. The film suction component 24 can be a component such as a fan that can provide suction, so that when the film suction table 23 is close to the diaphragm, the diaphragm can be sucked by the negative pressure of the film suction component 24, and the diaphragm is not easily damaged.

[0036] Combination Figure 1 and Figure 3, the displacement mechanism 3 and the diaphragm grabbing mechanism 2 are located above the diaphragm stage 12, the displacement mechanism 3 includes: a lifting assembly 32 and a transverse movement assembly 31. In this embodiment, the transverse movement assembly 31 is fixedly arranged above the two diaphragm mechanisms 1, including: a transverse movement rail 311 and a transverse movement member 312 arranged on the transverse movement rail 311. The transverse movement member 312 can be displaced on the transverse movement rail 311 by means of a cylinder or a linear guide rail, etc., which is not specifically limited in this embodiment. In addition, in this embodiment, the membrane tape transmission members 111 of the two diaphragm mechanisms 1 are arranged in parallel, and the setting direction of the transverse movement rail 311 is perpendicular to the transmission direction of the membrane tape transmission member 111, so as to reduce the space occupied by the membrane preparation mechanism. Of course, in other embodiments, the two membrane tape transmission members 111 can be at other angles, and the setting direction of the transverse movement rail 311 may not be perpendicular to the membrane tape transmission member 111.

[0037] In one embodiment, two lifting assemblies 32 are provided, which are respectively connected to two diaphragm grabbing mechanisms 2, and the two lifting assemblies 32 are connected to the transverse member 312. The lifting assemblies 32 can control the diaphragm grabbing mechanism 2 to approach or move away from the diaphragm stage 12 / preset station 5. The lifting assemblies 32 can be cylinders. When grabbing the diaphragm on the diaphragm stage 12, the lifting assemblies 32 control the diaphragm grabbing mechanism 2 to descend, and the film suction member 24 of the diaphragm grabbing mechanism 2 starts to absorb the diaphragm to avoid the situation where the height of the diaphragm grabbing mechanism 2 is too high and the diaphragm cannot be absorbed by suction; after absorbing the diaphragm, the lifting assemblies 32 control the diaphragm grabbing mechanism 2 to rise, and the transverse member 312 drives the lifting assemblies 32 and the diaphragm grabbing mechanism 2 to move. Lifting the diaphragm grabbing mechanism 2 first can avoid directly moving the diaphragm to rub the diaphragm on the diaphragm stage 12, causing damage to the diaphragm quality. After the film moves to the top of the preset station 5, the lifting mechanism controls the film grabbing mechanism 2 to descend to the thermal composite platform, the film suction member 24 is closed, and the film is released onto the metal wire 6 on the thermal composite platform. After the film is released, the lifting mechanism controls the film grabbing mechanism 2 to lift up and returns to the top of the film stage 12 through the transverse member 312. When one film grabbing mechanism 2 is located on the preset station 5, the other film grabbing mechanism 2 is located on the film stage 12, and the distance between the two film grabbing mechanisms 2 is always the same, so one transverse member 312 is provided, and the distance between the two lifting components 32 is the same. The height of the film stage 12 and the preset station 5 can be different. The two lifting components 32 respectively control the lifting and lowering of the two film grabbing mechanisms 2 to facilitate the absorption and release of the film.

[0038] In other embodiments, the film stage 12 is at the same height as the preset workstation 5, and one lifting assembly 32 can be provided, which is respectively connected to two film grabbing mechanisms 2, and when one film grabbing mechanism 2 is lowered onto the thermal composite platform, the other film grabbing mechanism 2 is lowered onto the film stage 12. Providing only one lifting assembly 32 can save costs and facilitate control.

[0039] The second embodiment of the present invention relates to a film preparation device, and the general embodiment is the same as the film preparation device in the first embodiment, and the main difference is that the number of the diaphragm mechanism 1 and the diaphragm grabbing mechanism 2 is greater than or equal to 3, and the moving trajectory of the transverse movement component 31 is annular. As shown in the figure, the diaphragm grabbing mechanism 2 passes through the preset station 5 in sequence. After the diaphragm grabbing mechanism 2 provides the diaphragm to the preset station 5, in the process of grabbing the diaphragm, another diaphragm grabbing mechanism 2 provides the diaphragm to the preset station 5, which greatly improves the film preparation efficiency.

[0040] The third embodiment of the present invention relates to a film preparation device, which is generally the same as the film preparation device in the first embodiment, with the main difference being that each diaphragm grabbing mechanism 2 in the first embodiment is connected to a displacement mechanism 3, while in the present embodiment, each diaphragm supply mechanism includes: a diaphragm mechanism 1, a diaphragm grabbing mechanism 2 and a displacement member 3, the displacement member 3 includes a displacement track and a driving member arranged between the diaphragm stage 12 and the preset station 5, the driving members of each diaphragm supply mechanism are electrically connected to the control module, the diaphragm grabbing mechanism 2 is arranged on the displacement track, and is displaced between the diaphragm stage 12 and the preset station 5 under the drive of the driving member, and the control module controls the diaphragm transmission of each diaphragm supply mechanism respectively.

[0041] A third embodiment of the present invention relates to a metal wire film processing device for processing a metal wire film. The metal wire film processing device includes the film preparation device of the first embodiment or the second embodiment, such as Figure 1 and Figure 2As shown, a thermal composite platform is provided on the preset workstation 5, and multiple metal wires 6 can be transmitted on the thermal composite platform. The transverse moving member 312 of the displacement mechanism 3 of the film preparation device controls the first film grabbing mechanism 21 to move to the top of the film platform 12, and controls the first film grabbing mechanism 21 to move downward through the lifting component 32, grabs the film and holds the film, and then lifts the height of the first film grabbing mechanism 21 through the lifting component 32, and moves the first film grabbing mechanism 21 and the film to the top of the thermal composite platform through the transverse moving member 312. At this time, the second film grabbing mechanism 22 is located above the corresponding film platform 12; the first film grabbing mechanism 21 is driven downward by the lifting component 32 thereon, and the first film grabbing mechanism 21 hot presses the film on the metal wire 6 of the thermal composite platform, wherein the metal wire 6 is a high-temperature metal wire 6. The second diaphragm grabbing mechanism 22 is driven downward by the lifting assembly 32 thereon to absorb the diaphragm; after completing one diaphragm hot pressing, the first diaphragm grabbing mechanism 21 located on the thermal composite platform is driven by the lifting assembly 32 thereon to rise, and at the same time, the second diaphragm grabbing mechanism 22 is driven by the lifting assembly 32 thereon to rise. The transverse member 312 drives the first diaphragm grabbing mechanism 21 to move toward the diaphragm stage 12, and at the same time, the second diaphragm grabbing mechanism 22 moves toward the thermal composite platform. At this time, the metal wire 6 is also transmitted forward, and the transmission distance is the side length of the diaphragm in the length direction of the metal wire 6, which is convenient for the next thermal composite. In the metal wire film processing equipment in this embodiment, since the film preparation device has a higher film supply efficiency, the thermal composite efficiency and overall processing efficiency of the metal wire film are also improved.

[0042] During the production process of the metal wire film, it is necessary to heat the composite film sheets on both sides of the metal wire 6, which is the composite side, and a film preparation device can only supply film on one composite side of the metal wire 6. Therefore, the metal wire film processing equipment in this embodiment has multiple film preparation devices. Two film preparation devices can be provided to supply film from both sides of the metal wire 6; four film preparation devices can also be provided, two by two are arranged on both sides of the metal wire 6, and two film sheets can be supplied to both sides of the metal wire 6 at one time, thereby improving the transmission speed of the metal wire 6 and further improving the processing efficiency of the metal wire film.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0044] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
