Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell string preparation technology, specifically to a membrane segment preparation device. Background Technology

[0002] A photovoltaic module's photovoltaic panel is made up of multiple battery strings connected together by busbars, and a battery string is made up of multiple battery cells connected together by solder ribbons. When laying solder ribbons on the battery cells, the solder ribbons need to be connected to the grid lines of the battery cells.

[0003] Common methods for connecting solder strips to solar cells include welding, adhesive bonding, and encapsulation film bonding. Because welding is costly and adhesive bonding suffers from poor conductivity, encapsulation film bonding is widely favored in the industry.

[0004] Existing adhesive film bonding solutions are mainly divided into film strip bonding and film sheet bonding. Film sheet bonding involves covering the solar cell with a single film, thereby positioning all the solder ribbons on the solar cell. Film strip bonding, on the other hand, involves cutting the film into strips and positioning each solder ribbon onto the solar cell using a separate film segment. Compared to film sheet bonding, film strip bonding saves more adhesive film and is considered a major research direction.

[0005] The existing mass production method for membrane strips involves pulling out the membrane sheet from the membrane roll, first dividing the membrane sheet into strips along its length, then using a puller to pull out the strips, and then placing the strips on a cutting platform for mass cutting to obtain the required membrane segments. The membrane segments are then picked up by a membrane segment transporter and transported to the surface of the solar cell. During the transport process, the membrane segments are spaced to ensure that the spacing between the membrane segments (the spacing between two segments along the length extension direction of each membrane segment) meets the requirements for attachment to the surface of the solar cell.

[0006] In existing technologies, membrane segment transporters need to achieve membrane segment separation during transport. The structure of membrane segment transporters is complex, and the stability requirements for membrane segment transporters are high, resulting in high membrane segment production costs. Utility Model Content

[0007] The membrane segment production device designed in this utility model can overcome the shortcomings of the prior art, which requires membrane segment transporters to achieve membrane segment separation during transport, has a complex structure, and has high stability requirements, resulting in high membrane segment production costs.

[0008] The purpose of this utility model is to provide a membrane segment production device, including a membrane segment placement mechanism, a sliding assembly, a sliding drive component, and a membrane strip cutting mechanism. The sliding assembly includes a guide rail and multiple sliders slidably connected to the guide rail. The membrane segment placement mechanism includes multiple membrane segment placement assemblies, each with a membrane segment placement platform for adsorbing, positioning, and cutting the formed membrane segments. Each slider is fixedly connected to each membrane segment placement assembly, and the membrane segment placement assemblies are spaced apart along the sliding guide direction of the guide rail. The membrane segment placement mechanism has a first state and a second state. When the membrane segment placement mechanism is in the first state, each membrane segment placement assembly has a first gap in the sliding guide direction, and the membrane strip cutting mechanism can cut the membrane strip between two adjacent membrane segment placement assemblies. When the membrane segment placement mechanism is in the second state, each membrane segment placement assembly has a second gap in the sliding guide direction that is greater than the first gap. The sliding drive component drives the membrane segment placement mechanism to switch between the first state and the second state.

[0009] In some embodiments, each of the membrane segment placement components further includes a sliding bracket, and the membrane segment placement platform and the slider are both fixedly connected to the sliding bracket. Each sliding bracket has a spacing adjustment groove and a limiting post. The groove of each spacing adjustment groove extends along the sliding guide direction. The limiting post of one of two adjacent sliding brackets is slidably inserted into the spacing adjustment groove of the other. The sliding bracket located at the outermost first end of each sliding bracket is a first bracket, and the first bracket is connected to the driving end of the sliding drive component. The sliding bracket located at the outermost second end of each sliding bracket is a second bracket, and the slider fixedly connected to the second bracket is fixedly connected to the guide rail.

[0010] In some embodiments, the sliding assembly has two sets, the two sets of sliding assemblies being symmetrically located on the left and right sides of the spacing adjustment groove of each sliding bracket; and / or, each limiting post is detachably assembled on the sliding bracket, the spacing adjustment groove is formed on the adjustment block, and each adjustment block is detachably assembled on the sliding bracket; and / or, the sliding bracket is a rectangular frame.

[0011] In some embodiments, the film strip cutting mechanism has a film strip cutting state and a film segment removal state. When the film strip cutting mechanism is in the film strip cutting state, it can cooperate with each of the film segment placement platforms to cut the film strip that extends continuously along the sliding guide direction into each of the film segments. When the film strip cutting mechanism is in the film segment removal state, it can be located outside each of the film segment placement platforms, and it can be driven to switch between the film strip cutting state and the film segment removal state.

[0012] In some embodiments, the film strip cutting mechanism switches between the film strip cutting state and the film segment removal state by flipping; and / or, each of the film segment placement platforms is respectively provided with a set of the film strip cutting mechanisms.

[0013] In some embodiments, the film strip cutting mechanism includes a flipping drive component and a cutting assembly. The cutting assembly includes a cutting bracket and a cutting blade assembly assembled on the cutting bracket. A first end of the cutting bracket is hinged to the sliding bracket. The flipping drive component is capable of driving the cutting bracket to rotate about its hinge point with the sliding bracket.

[0014] In some embodiments, the flipping drive component is a telescopic cylinder, the cylinder barrel of which is hinged to the sliding bracket, the driving end of the piston rod of the telescopic cylinder is hinged to the cutting bracket, and the hinge position of the driving end and the cutting bracket is on the side away from the first end of the cutting bracket at the hinge point between the cutting bracket and the sliding bracket.

[0015] In some embodiments, the cutting bracket has a film strip holding surface corresponding to the position of the film segment placement platform. When the film strip cutting mechanism is in the film strip cutting state, the film strip holding surface and the film segment placement platform together form a clamping effect on the film strip located between them.

[0016] In some embodiments, the cutter assembly includes a cutter lateral movement drive assembly and a blade component, the blade component including a blade, the cutter lateral movement drive assembly being capable of driving the blade to laterally move in a direction perpendicular to the sliding guide direction, and the cutter assembly being assembled on the cutting bracket via the cutter lateral movement drive assembly.

[0017] In some embodiments, the blade is a circular blade, and the blade component further includes a rotary motor, with the circular blade coaxially fixedly connected to the output end of the rotary motor shaft.

[0018] The membrane segment production device of this utility model includes a membrane segment placement mechanism comprising multiple membrane segment placement components arranged along the sliding guide direction of a guide rail. Each membrane segment placement component is slidably connected to the guide rail. In this way, the spacing between each membrane segment placement component can be changed by a sliding drive component, thereby enabling the membrane segment placement mechanism to switch between the aforementioned first state and second state. This allows for adjustment of the longitudinal spacing (i.e., the spacing along the length direction of the membrane segment) of each membrane segment after the membrane strip is cut into multiple membrane segments along its length direction, achieving the separation purpose after cutting. The structure design and control are simple. After the longitudinal separation of each membrane segment is completed, the corresponding membrane segments can be directly transported and placed on the target solar cell by a corresponding transporter. The transporter does not need to be configured to be able to separate during the transport process, which greatly reduces the structural design of the transporter and reduces the cost of membrane segment production and transportation.

[0024] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. In the drawings, for clarity, the thickness of regions and layers is exaggerated. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0025] The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0026] The following example describes a membrane segment preparation device of this utility model. This example is only a part of the embodiments of this utility model, but the protection scope of this utility model is not limited thereto. All other embodiments obtained by those skilled in the art without inventive effort should be covered within the protection scope of this utility model.

[0027] See also Figures 1 to 4As shown in the figure, according to an embodiment of the present invention, a membrane segment preparation device is provided, including a membrane segment placement mechanism (not labeled in the figure), a sliding assembly (not labeled in the figure), a sliding drive component 3, and a membrane strip cutting mechanism 4. The sliding assembly includes a guide rail 21 and a plurality of sliders 22 slidably connected to the guide rail 21. The guide rail 21 is specifically fixedly assembled on a corresponding base plate. The membrane segment placement mechanism includes a plurality of membrane segment placement assemblies 11, each of which has a membrane for adsorbing, positioning, and cutting the formed membrane segments. The membrane segment placement platform 111, as understood, ensures that each membrane strip, spaced along the width direction of each membrane segment placement platform 111, is reliably adsorbed onto the corresponding membrane segment placement platform 111 before being cut into multiple membrane segments. Specifically, each membrane segment placement platform 111 has a vacuum adsorption hole (not shown in the figure, such as a vacuum pump) controllably connected to a vacuum negative pressure source (not shown in the figure). Each slider 22 is fixedly connected to each membrane segment placement assembly 11, and each membrane segment placement assembly 11 is positioned along the guide rail 2. The sliding guide direction of the 1 is spaced apart. The membrane segment placement mechanism has a first state and a second state. When the membrane segment placement mechanism is in the first state, each membrane segment placement component 11 has a first spacing in the sliding guide direction, and the membrane strip cutting mechanism 4 can cut the membrane strip between two adjacent membrane segment placement components 11. When the membrane segment placement mechanism is in the second state, each membrane segment placement component 11 has a second spacing greater than the first spacing in the sliding guide direction. The sliding drive component 3 (which can also be assembled on the aforementioned base plate) is used to drive the membrane segment placement mechanism to switch between the first state and the second state. In a specific embodiment, the aforementioned sliding drive component 3 can be a telescopic cylinder. It should be noted that the aforementioned first spacing is generally small and is reasonably selected according to the thickness of the cutter of the aforementioned membrane strip cutting mechanism 4. Specifically, the aforementioned first spacing is also the size of the cutting gap of the cutter. The size of the aforementioned second spacing is reasonably selected according to the longitudinal spacing of each battery cell in the actual battery string.

[0028] In this technical solution, the membrane segment placement mechanism includes multiple membrane segment placement components 11 arranged along the sliding guide direction of the guide rail 21, and each membrane segment placement component 11 is slidably connected to the guide rail 21. In this way, the spacing of each membrane segment placement component 11 can be changed by the sliding drive component 3, that is, the membrane segment placement mechanism can switch between the aforementioned first state and second state. In this way, after each membrane strip is cut into multiple membrane segments along its length direction, the longitudinal spacing of each membrane segment (that is, the spacing along the length direction of the membrane segment) can be adjusted to achieve the separation purpose after cutting. The structural design and control are simple. After the longitudinal separation of each membrane segment is completed, the corresponding membrane segments can be directly transported and placed on the target solar cell by the corresponding transporter. The transporter does not need to be configured to be able to separate during the transport process, which greatly reduces the structural design of the transporter and reduces the cost of membrane segment manufacturing and transportation.

[0029] In some embodiments, each of the membrane segment placement assemblies 11 further includes a sliding bracket 112. The membrane segment placement platform 111 and the slider 22 are both fixedly connected to the sliding bracket 112. Each sliding bracket 112 has a spacing adjustment groove 1121 and a limiting post 1122. The groove of each spacing adjustment groove 1121 extends along the sliding guide direction. It is understood that the extension length of the aforementioned spacing adjustment groove 1121 is determined based on the difference between the aforementioned second spacing and the first spacing. One of two adjacent sliding brackets 112 has a limiting post 1122 that is slidably inserted into the spacing adjustment groove 1121 of the other. The sliding bracket 112 located at the outermost first end of each sliding bracket 112 is the first bracket, which is connected to the driving end of the sliding drive component 3. The sliding bracket 112 located at the outermost second end of each sliding bracket 112 is the second bracket. The slider 22 fixedly connected to the second bracket is fixedly connected to the guide rail 21. Figure 1 The orientation shown is for reference only. The first support mentioned above is the sliding support 112 located on the far right of the orientation shown in the figure, and the second support mentioned above is the sliding support 112 located on the far left of the orientation shown in the figure.

[0030] In this technical solution, by simultaneously setting limiting posts 1122 and spacing adjustment grooves 1121 on each sliding bracket 112, and by using sliding insertion limiting between the first limiting post 1122 and the second spacing adjustment groove 1121 between two adjacent sliding brackets 112, the second spacing between each membrane segment placement platform 111 is accurately determined. The structure is very simple.

[0031] It is understood that the extension direction of the aforementioned spacing adjustment groove 1121 should be parallel to the sliding guide direction.

[0032] In one specific embodiment, the sliding support 112 is a rectangular frame, and the membrane segment placement platform 111 and the slider 22 are respectively located on the top and bottom sides of the rectangular frame. The rectangular frame configuration makes the structure of the membrane segment placement assembly 11 more compact and reasonable.

[0033] In some embodiments, the sliding assembly has two sets, which are symmetrically located on the left and right sides of the spacing adjustment groove 1121 of each sliding bracket 112, thereby providing more reliable sliding guidance for each sliding bracket 112.

[0034] In one specific embodiment, each of the limiting posts 1122 is detachably assembled onto the sliding bracket 112, and the spacing adjustment groove 1121 is formed on the adjustment block 1123. Each of the adjustment blocks 1123 is detachably assembled onto the sliding bracket 112. By detachably assembling the limiting posts 1122 and the adjustment blocks 1123 onto the sliding bracket 112, the limiting posts 1122 and the adjustment blocks 1123 can be adjusted according to the size requirement of the second spacing, thereby improving the versatility of the device.

[0035] In some embodiments, the film strip cutting mechanism 4 has a film strip cutting state and a film segment removal state. When the film strip cutting mechanism 4 is in the film strip cutting state, it can cooperate with each of the film segment placement platforms 111 to cut the film strip that extends continuously along the sliding guide direction into each of the film segments. When the film strip cutting mechanism 4 is in the film segment removal state, it can be located outside each of the film segment placement platforms 111, and it can be driven to switch between the film strip cutting state and the film segment removal state.

[0036] In this technical solution, the membrane strip cutting mechanism 4 is driven to switch between the membrane strip cutting state and the membrane segment removal state, which can realize the cutting and transfer of membrane segments and improve the efficiency of battery cell manufacturing.

[0037] In some embodiments, the film strip cutting mechanism 4 switches between the film strip cutting state and the film segment removal state by flipping. Specifically, the film strip cutting mechanism 4 includes a flipping drive component 41 and a cutting assembly (not labeled in the figure). The cutting assembly includes a cutting bracket 421 and a cutting blade assembly (not labeled in the figure) assembled on the cutting bracket 421. The first end of the cutting bracket 421 is hinged to the sliding bracket 112 (specifically, it is rotatably connected by a pin). The flipping drive component 41 can drive the cutting bracket 421 to rotate about its hinge point with the sliding bracket 112.

[0038] In this technical solution, one end of the film strip cutting mechanism 4 is hinged to the sliding bracket 112, so that the film strip cutting mechanism 4 can switch between the film strip cutting state and the film segment removal state in a flipping manner, making the device structure more simplified and compact.

[0039] In some embodiments, the flipping drive component 41 is a telescopic cylinder, the cylinder barrel of which is hinged to the sliding bracket 112. The driving end of the piston rod of the telescopic cylinder is hinged to the cutting bracket 421 near its first end, and the hinge position between the driving end and the cutting bracket 421 is on the side away from the first end of the cutting bracket 421 at the hinge point between the cutting bracket 421 and the sliding bracket 112. See details. Figure 2 As shown, the telescopic cylinder is specifically set in the hollow area of ​​the aforementioned rectangular frame, making the structure more reasonable and compact.

[0040] In some embodiments, the cutting bracket 421 has a film strip holding surface (not labeled in the figure) corresponding to the position of the film strip placement platform 111. When the film strip cutting mechanism 4 is in the film strip cutting state, the film strip holding surface and the film strip placement platform 111 together form a clamping of the film strip between them, so as to ensure that the position of each film strip is reliable and stable when it is being cut.

[0041] In some embodiments, the cutting assembly includes a cutting lateral movement drive assembly 422 and a blade component (not shown in the figure). The blade component includes a blade 423. The cutting lateral movement drive assembly 422 can drive the blade 423 to move laterally in a direction perpendicular to the sliding guide direction. The cutting assembly is assembled on the cutting bracket 421 via the cutting lateral movement drive assembly 422. Specifically, the cutting lateral movement drive assembly 422 can be a rodless cylinder. When the film strip cutting mechanism 4 is in the film strip cutting state, the film strip holding surface of the cutting bracket 421 presses against each film strip to ensure its positional reliability. At the same time, the cutting lateral movement drive assembly 422 is controlled to drive the blade 423 to move laterally, thereby realizing the cutting of each film strip.

[0042] In this technical solution, compared with the existing technology of using the lifting and lowering of the blade to cut the membrane strip below it, the blade in this utility model achieves sequential cutting of each membrane strip by sliding laterally. The blade 423 does not need to cover all membrane strips at once, which reduces the requirements of the cutter 423 and thus reduces the cost of membrane segment production.

[0043] In some embodiments, the blade 423 is a circular blade, and the blade component also includes a rotary motor (not shown in the figure). The circular blade is coaxially fixedly connected to the output end of the rotary motor shaft. In this way, after the circular blade becomes dull at a certain circumferential position after a long period of use, the rotary motor can be controlled to rotate at a certain angle, that is, to adjust the other circumferential position of the circular blade to cut the film strip without replacing the blade 423, thereby improving the service life of the blade.

[0044] In one specific embodiment, each of the membrane segment placement platforms 111 is respectively provided with a set of membrane strip cutting mechanisms 4, so that the membrane strip cutting mechanism 4 that can achieve cutting can be controlled according to the actual number of membrane segments required, thereby improving the flexibility of the device.

[0045] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
