Technical Field

[0001] This application belongs to the field of photovoltaic module manufacturing technology, specifically, it relates to a movable carrier plate. Background Technology

[0002] When processing products that are lightweight, thin, large in size, and highly flexible, fixed vacuum adsorption carriers are often used to support the product, allowing it to be flattened before undergoing high-precision multi-process machining. However, all processes must be completed on the same fixed vacuum adsorption carrier, and the processed product cannot be transferred between processes with the carrier. When the size of the processed product is large, the process requirements are numerous, and the production capacity requirements are high, traditional fixed vacuum adsorption carriers cannot meet the production needs. In addition, current carriers have a short service life, poor vacuum adsorption, and lack heating functions. Utility Model Content

Each adsorption hole is connected to the corresponding weight reduction unit, so that each adsorption hole is connected to the gas transmission port through the corresponding second vent hole and the first vent hole.

Detailed Implementation

[0023] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] refer to Figure 1-4 This application provides a movable carrier plate (hereinafter referred to as the carrier plate), including an adsorption panel 1, a base plate 3, and an intermediate plate 2 disposed between the adsorption panel 1 and the base plate 3. The adsorption panel 1 is provided with a plurality of adsorption holes 11 penetrating the adsorption panel 1. The base plate 3 is provided with a gas transmission port 31. The intermediate plate 2 includes a support frame 21 and a weight-reducing part 22 disposed in a hollow cavity 211 formed by the support frame 21. A gas transmission channel is provided between the weight-reducing part 22 and the support frame 21. The weight-reducing part 22 is connected to the corresponding adsorption hole 11, and the gas transmission port 31 is connected to the gas transmission channel.

[0026] When it is necessary to adsorb and fix the processed product onto the carrier plate, the vacuum generator (not shown in the figure) is connected to the gas transmission port 31. The vacuum generator draws a vacuum to create a negative pressure in each adsorption hole 11, thereby adsorbing the processed product onto the carrier plate.

[0027] This application allows a vacuum generator to be installed on the base plate 3. The vacuum generator moves together with the carrier plate. During the process of the carrier plate being transferred between the processing stations of each process, the vacuum generator is always in the start state and is connected to the gas transmission port 31, so that the processed product is always adsorbed and fixed on the adsorption panel 1 during the transfer between each process.

[0028] Alternatively, along the conveying direction of the carrier plate, at least one gas transmission port 31 is provided at each end of the carrier plate, and a vacuum generator is provided at each processing station of each process, with two adjacent processing stations set up close to each other. Taking the transfer of the carrier plate between two adjacent processing stations as an example, this method is explained as follows: When the carrier plate is at the previous processing station, the gas transmission port 31 at one end is connected to the vacuum generator at that processing station. After processing, during the transfer from that processing station to the next processing station, the vacuum generator continuously evacuates the carrier plate. When the carrier plate is transferred to the next processing station, the gas transmission port 31 at the other end of the carrier plate is connected to the vacuum generator at that processing station, and the carrier plate is evacuated through the vacuum generator. At the same time, the gas transmission port 31 connected to the vacuum generator at the previous processing station is separated from the vacuum generator and closed and sealed, so that the carrier plate can continue to be transferred forward. Thus, during the transfer between processing stations, the carrier plate is always in a vacuum state, and the processed product is always adsorbed and fixed on the carrier plate.

[0029] The structure of the supporting frame 21 can be as follows: Figure 3-4 The structure shown consists of an outer frame 212 and multiple parallel long supports 213 arranged within and connected to the outer frame 212 along a first direction, and multiple parallel short supports 214 arranged along a second direction. The first and second directions are perpendicular to each other in the same plane, i.e., the long supports 213 and short supports 214 are perpendicular to each other, thus forming a mesh-like support frame 21 and multiple hollow cavities 211. Of course, the long supports 213 and short supports 214 do not have to be perpendicular to each other; they only need to intersect to form a mesh-like support frame 21. This application does not impose specific limitations on this. Alternatively, it can consist only of an outer frame 212 and multiple parallel long supports 213 arranged within and connected to the outer frame 212 along the first direction, or it can consist of an outer frame 212 and multiple parallel short supports 214 arranged within and connected to the outer frame 212 along the second direction.

[0030] Each hollow cavity 211 is provided with a weight reduction part 22. Through the cooperation of the support frame 21 and the weight reduction part 22, the weight of the load-bearing plate can be reduced while providing support, ensuring the flatness of the load-bearing plate, and facilitating the movement of the load-bearing plate between processes.

[0031] Each weight-reducing section 22 includes multiple hollow weight-reducing units 221 that abut against each other (see reference). Figure 4This forms a honeycomb-like structure. For example, the sidewalls of two adjacent weight-reducing units 221 can abut against each other, or two adjacent weight-reducing units 221 can share a sidewall (i.e., each weight-reducing part 22 is integrally formed).

[0032] In one specific implementation, reference Figure 4 The gas transmission channel includes a plurality of first vent holes 215 formed on the support frame 21 and a second vent hole 222 formed on the side wall of the weight reduction unit 221. Each weight reduction unit 221 in each weight reduction part 22 is connected to each other through the second vent hole 222 and connected to the corresponding first vent hole 215 on the support frame 21 through the corresponding second vent hole 222. Each adsorption hole 11 is connected to the corresponding weight reduction unit 221, so that each adsorption hole 11 is connected to the gas transmission port 31 through the corresponding second vent hole 222 and the first vent hole 215.

[0033] After the vacuum generator connected to the gas transmission port 31 is started, the airflow is drawn out sequentially along the adsorption hole 11, the second vent hole 222, the first vent hole 215, and the gas transmission port 31, so that each adsorption hole 11 generates negative pressure to adsorb and fix the processed product on the adsorption panel 1.

[0034] In a preferred embodiment, each weight-reducing unit 221 has an opening at its top, which communicates with the corresponding adsorption hole 11. For example, each weight-reducing unit 221 is only enclosed by a side wall, and its top and bottom are both open, so that the adsorption hole 11 corresponding to the weight-reducing unit 221 can communicate with the second vent hole 222 on the side wall of the weight-reducing unit 221.

[0035] In this embodiment, the number of adsorption holes 11 corresponding to each weight reduction unit 221 is not specifically limited. For example, a weight reduction unit 221 may be connected to only one adsorption hole 11, or a weight reduction unit 221 may be connected to multiple adsorption holes 11. The specific design can be made according to the actual cutting pattern, adsorption effect, adsorption area and other factors.

[0036] The gas transmission port 31 in this embodiment can be as follows: Figure 4The hollow cavity 211 connected to the support frame 21 is provided with multiple weight-reducing units 221 in the area of ​​the hollow cavity 211 except for the area connected to the gas transmission port 31, so that the area of ​​the hollow cavity 211 except for the area connected to the gas transmission port 31 is filled with weight-reducing units 221. When the vacuum generator is started, the airflow is transmitted to the corresponding weight-reducing unit 221 through the adsorption hole 11, and flows between each weight-reducing unit 221 and the support frame 21 through the second vent hole 222 and the first vent hole 215, and gathers in the weight-reducing unit 221 in the hollow cavity 211 connected to the gas transmission port 31, and then gathers in the gas transmission port 31 and is extracted by the vacuum generator, so that the airflow channel in the carrier plate forms a negative pressure, and thus the adsorption hole 11 forms a negative pressure.

[0037] The processed products can be relatively thin and flexible, such as copper foil, aluminum foil and other metal foils.

[0038] The carrier plate of this application can be used to laser cut metal foil (i.e., the processed product is metal foil), and then the laser-cut metal foil is transferred to the subsequent processes for corresponding processing.

[0039] In a preferred embodiment, the adsorption hole 11 is staggered from the laser cutting path of the processed product. This allows the effective metal foil to continue to be adsorbed on the carrier plate after laser cutting, while the waste metal foil formed after cutting is not adsorbed on the carrier plate, so that the waste metal foil can be removed in the subsequent process.

[0040] In a preferred embodiment, refer to Figure 1-3 A flexible film layer 4 is provided on the side of the adsorption panel 1 away from the middle plate 2. The adsorption hole 11 penetrates the flexible film layer 4. The flexible film layer 4 is provided with a clearance groove 41 along the laser cutting path of the processed product. More preferably, a patch 42 is provided in the clearance groove 41.

[0041] If the processed product is directly in contact with the adsorption panel 1 and is adsorbed and fixed on the adsorption panel 1, the short-term local high temperature generated by the laser during the laser cutting process will cause the processed product to produce a large irreversible thermal stress deformation, which will cause gaps to form between the processed product and the adsorption holes 11 on the adsorption panel 1, resulting in vacuum leakage and a decrease in the adsorption between the processed product and the adsorption panel 1. It may even cause the position of the processed product to shift during the processing or during the movement of the carrier plate.

[0042] Therefore, the flexible film layer 4 allows the processed product to not directly contact the adsorption panel 1, but to directly contact the flexible film layer 4 during adsorption. This results in a better adsorption and fixation effect between the processed product and the carrier plate, ensuring that the processed product is always adsorbed and fixed on the carrier plate during the processing and movement of the carrier plate, thus ensuring the processing accuracy of the processed product.

[0043] Furthermore, the flexible membrane layer 4 can be made of materials such as rubber, polyimide, and Teflon.

[0044] Continue to refer to Figure 2-3 This application processes an avoidance groove 41 along the laser cutting path on the flexible film layer 4, and places a patch 42 within the avoidance groove 41. This avoids damage to the adsorption panel 1 caused by fumes and laser action during laser cutting, thus ensuring the flatness of the adsorption panel 1 and extending its service life. Furthermore, processing the avoidance groove 41 on the flexible film layer 4 significantly reduces the time and cost of processing the avoidance groove 41 compared to directly processing it on the adsorption panel 1. The patch 42 within the avoidance groove 41 also avoids the maintenance and cleaning difficulties caused by the gradual accumulation of molten metal slag generated during laser cutting. In addition, during prolonged laser cutting, the patch 42 and the flexible film layer 4 can be replaced periodically to prevent damage to the patch 42 from prolonged laser exposure, thus ensuring the processed product remains adsorbed and fixed on the carrier plate without vacuum leakage.

[0045] The material of patch 42 can be made of laser sputtering resistant materials, such as stainless steel sheet metal, ceramic, slab or artificial stone.

[0046] In a further preferred embodiment, the adsorption panel 1 is provided with a plurality of mounting slots on the side facing the middle plate 2, and a heating unit is installed in each mounting slot. Preferably, the mounting slots are staggered from the adsorption holes 11 to avoid the heating units blocking the adsorption holes 11 and affecting the adsorption effect of the adsorption holes 11.

[0047] During the processing of the metal backsheet of a photovoltaic module, after the metal foil is laser-cut and the waste metal foil is removed, the effective metal foil needs to be brought into contact with the adhesive layer on the backsheet, and the adhesive layer is melted by lamination to bond the effective metal foil to the backsheet.

[0048] This application provides multiple mounting slots on the side of the adsorption panel 1 facing the intermediate plate 2, and installs heating units in the mounting slots. When the carrier plate carrying the effective metal foil is conveyed to the lamination station, the back plate, adhesive layer and effective metal foil are pressed together by the lamination plate. The heating unit can heat the adsorption panel 1, thereby heating the effective metal foil on the adsorption panel 1, which in turn causes the adhesive layer in contact with the effective metal foil to melt. After lamination, the effective metal foil is bonded to the back plate.

[0049] In a further implementation, refer to Figure 1-2 The adsorption panel 1 is provided with multiple vision positioning parts 5. When cutting the processed product near the corresponding vision positioning part 5, the vision positioning device (such as a camera) automatically identifies the vision positioning part 5, and obtains the correct position of the graphic to be cut according to the compensation value, and then makes the laser cut along the correct laser cutting path to ensure the laser cutting accuracy.

[0050] In another preferred embodiment, reference Figure 3 The base plate 3 is provided with multiple positioning holes 6. Each processing station of each process is provided with a positioning pin that matches the positioning hole 6. When the carrier plate is conveyed to the processing station of the corresponding process, the positioning pin of the processing station is inserted into the positioning hole 6 on the base plate 3 to position the carrier plate at the processing station.

[0051] In order to make the positioning of the carrier plate at the corresponding processing station more accurate, this embodiment can symmetrically set positioning holes 6 at opposite ends of the base plate 3. For example, two or more positioning holes 6 can be machined at one end of the base plate 3 and two or more positioning holes 6 can be symmetrically machined at the opposite end; or one positioning hole 6 can be machined at each of the four top corners of the base plate 3.
