Detailed Description

For a better understanding of the present invention, reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings.

Referring to fig. 1 to 3, the present application provides a membrane separation device, which includes an adsorption device 1, a support frame 2 and a driving device.

Specifically, the adsorption surface of the adsorption device 1 is used for adsorbing the film to be separated, and the adsorption device 1 includes a plurality of adsorption blocks, and the adsorption surface of each adsorption block corresponds to one of the films to be separated. A plurality of absorption pieces are all established on support frame 2, and at least one absorption piece and support frame 2 sliding connection. Drive arrangement is connected with at least one absorption piece, and drive arrangement is used for the drive with support frame 2 sliding connection's absorption piece to make a plurality of absorption pieces laminate each other or mutual separation.

Therefore, the driving device is matched with part of the adsorption blocks to realize the mutual movement of the adsorption blocks, so that the film positioned on the adsorption surface is divided into a plurality of really independent single sheets, a starting function is realized on a laser cutting process and a single sheet interconnection production process, and the whole production process of the solar thin film battery can be smoothly carried out. And the whole device has simple structure, simple and convenient operation and low cost.

In the specific embodiment of the present application, the adsorption device 1 includes adsorption blocks in X rows and N columns, and X, N is a positive integer greater than or equal to 1. The support frame 2 comprises X rows of slide bars, and one row of adsorption blocks in the X rows is arranged in one row of the X rows of slide bars.

For example, the suction device 1 shown in fig. 2 may include two rows and five columns of suction blocks, and the ten suction blocks are driven by the driving device to move relative to each other, so that the pellicle is divided into ten truly independent single sheets. The slide bars mainly serve as a guide, and each row of slide bars can comprise two first optical axes 211 or two second optical axes 221 which are symmetrically arranged according to the following description, so that the whole device can be more stable in movement. Of course, in practical applications, the plurality of suction blocks may be arranged according to the actual requirement and the rest number of rows and columns, and the slide bars may be arranged according to other manners according to the actual requirement.

In a specific implementation process, the driving device includes X first driving devices 3 and second driving devices 4, the X first driving devices 3 are respectively connected to a row of adsorption blocks, and one first driving device 3 is configured to drive N adsorption blocks included in a row to move relative to each other. The second driving device 4 is used for driving the X-row adsorption blocks to move mutually.

For example, the second driving device 4 can drive the X-line absorption blocks to move relative to each other in the following two ways: the first and the above second driving device 4 comprises a plurality of second slider driving devices 41, wherein one second slider driving device 41 is connected between two adjacent rows of adsorption blocks, and each second slider driving device 41 drives two adjacent rows of adsorption blocks to be separated from each other so as to realize the separation between X rows of adsorption blocks.

Second, the second driving device 4 includes a second sliding driving device 41 and an elastic member 32, and similarly to the structural connection manner of the following row of suction blocks that move relative to each other by the elastic member 32, the following X first slider driving devices 31 move relative to each other by the elastic member 32 or the following X driving blocks fixed below the X first slider driving devices 31 move relative to each other by the elastic member 32, and the X row of suction blocks move relative to each other by the second slider driving device 41. In practical applications, of course, the second driving device 4 may also adopt other structures and connection manners to move the X-line adsorption blocks to each other so that the film is first divided into truly independent X-lines.

In order to ensure the quality of each single chip obtained after the film is divided into truly independent single chips, when the X first driving devices 3 drive the N adsorption blocks in one row to move mutually and/or the second driving devices 4 drive the X adsorption blocks to move mutually, the moving distance between two adjacent adsorption blocks is equal. For example, for each row of suction blocks, the N suction blocks in each row may be equally spaced by equalizing the compressed elastic force of each elastic member 32 when the suction blocks are bonded to each other, and equalizing the sum of the compressed elastic forces of all the elastic members 32 with the output force of the second slider driving device 41.

In a possible implementation manner, each adsorption block is composed of a vacuum chamber and a vacuum adsorption plate 15 fixed at the top of the vacuum chamber, a plurality of adsorption holes are formed in the vacuum adsorption plate 15, an area where the adsorption holes are located forms an adsorption area, a vacuum channel 16 is arranged in the vacuum chamber, and the vacuum channel 16 is communicated with the adsorption holes. In the specific use process, a quick-connection plug 17 can be connected to the end part of each vacuum channel 16, and a vacuum generator is connected with the quick-connection plug 17 to form vacuum negative pressure, so that the film is tightly attached to the adsorption surface under the action of vacuum adsorption force. Of course, the structure of the adsorption block can be designed into other forms according to actual needs. The vacuum generator may be replaced by a vacuum pump or other vacuum source as long as the vacuum suction force can be generated to achieve the purpose of adsorbing the thin film, and this embodiment is merely an example, and is not limited thereto.

In a specific implementation, since the volume of each adsorption block is small, in order to facilitate the arrangement of the vacuum channels 16 to save space, the vacuum channels 16 in each vacuum chamber are obliquely arranged (refer to fig. 5). In addition, since the film is generally very light, in order to prevent the film from being tilted in the opposite direction due to an excessive suction force and to ensure the best suction effect on the film, the suction area on the suction surface of each suction block is an annular suction area, and the annular suction area is spaced from the boundary of the vacuum suction plate 15 (see fig. 2).

In the prior art, in the production process of a solar thin film battery, a series of processes are required for processing a thin film, and when an Epitaxial lift-off process (ELO) is performed, the thin film is light and soft, and a hard carrier is required to smoothly lift off the thin film. Thus, the ELO process requires that the frame and film be first bonded together with a glue (e.g., Pressure Sensitive Adhesive (PSA)) and then the film be peeled off to yield the framed film 6.

Therefore, the film 6 with the frame is still formed after the subsequent laser cutting process, and at this time, a truly independent single sheet cannot be obtained due to the process reason of the laser cutting process itself, and in the prior art, the film is generally divided once again by the device to obtain the truly independent single sheet. However, in the existing device, each adsorption block is independent from each other, is connected with a motor, and automatically controls each motor through a control program, and although the automation degree is high, the whole device is very large in size, complex in structure and high in cost. The film separating device in the embodiment has the advantages of simple structure, small volume and great cost saving.

In practical application, in order to remove the frame on the film after the laser cutting process conveniently, and ensure that the film can be more accurately adsorbed right above the adsorption area, the quality of the film is prevented from being influenced by the deviation of the placement position of the film, and the film separation device further comprises a positioning device 5. Specifically, the positioning device 5 may include a first guide block 51 and a second guide block 52 respectively located in the X-axis direction and the Y-axis direction as shown in fig. 4, and the first guide block 51 and the second guide block 52 are respectively supported above the adsorption region by a certain distance (generally about 3 mm) through a support 53, so as to position the placement position of the film.

When the vacuum film separating device is used, a vacuum generator is generally turned on to provide vacuum negative pressure, then an operator holds the film 6 with the frame (note that the film 6 with the frame needs to be placed in a mode that the frame faces upwards and the film faces downwards) by hands, and places the film 6 with the frame right above the adsorption surface by utilizing the positioning action of the first guide block 51 and the second guide block 52, at the moment, the film can be tightly attached to the adsorption surface of the adsorption device 1 under the action of vacuum adsorption force, and then the function of manually separating the frame is realized, and the vacuum film separating device is simple and convenient. Naturally, the separation of the frame may be realized by other structural manners, and this embodiment is merely an example, and is not limited thereto.

In an embodiment of the present application, referring to fig. 6 to 9, the first driving device 3 includes an elastic element 32, at least one of the X rows of suction blocks includes a fixed block 13 fixedly connected to the supporting frame 2 and a sliding block 14 located at least one side of the fixed block 13, and the sliding block 14 is slidably connected to the supporting frame 2. The elastic member 32 is disposed between the second to N-1 th adsorption blocks.

Here, the elastic member 32 may be a spring, or may be another member having elasticity. The fixing manner of the fixing block 13 may be fixed on the two first optical axes 211 or the two second optical axes 221 by the jackscrew bolt 18, which will be described below, but of course, other manners may also be adopted to realize the fixing, and this embodiment is merely an example. Therefore, the second to the N-1 adsorption blocks can move mutually by compressing and bouncing off the elastic piece 32, and the device has the advantages of simple structure, simple and convenient operation and low cost.

Specifically, the first driving device 3 further includes two guide shafts 33, the two guide shafts 33 respectively pass through the through holes of the second to M-1 th adsorption blocks and the through holes of the M +1 to N-1 th adsorption blocks, and M is a positive integer greater than 1 and smaller than N. One ends of the two guide shafts 33 are respectively arranged at two sides of the fixed block 13, the other ends of the two guide shafts 33 are respectively provided with a limiting step, and the diameter of the limiting step is larger than that of the through hole. The elastic member 32 is fitted over the guide shaft 33 between the two suction blocks.

The guide shaft 33 also plays a role of guiding, the M-th adsorption block is the position of the fixed block 13, and the adsorption blocks on both sides of the fixed block 13 are the sliding blocks 14. In practical application, according to the specific structure shown in fig. 6, through holes for the guide shaft 33 to pass through are provided in the fixed block 13 and the sliding block 14, the through holes provided in the second and N-1 th adsorption blocks are stepped holes, and the stepped holes respectively include a first hole close to the first adsorption block and the nth adsorption block and a second hole connected to the first hole. One end of the guide shaft 33 is fixedly connected with the fixed block 13, the diameter of a limiting step arranged at the other end of the guide shaft 33 is larger than that of the second hole and smaller than that of the first hole, and the diameters of the through holes in the first adsorption block and the Nth adsorption block are larger than or equal to that of the first hole. In the axial direction of the guide shaft 33, a certain distance exists between the limiting step and the plane opposite to the first hole.

More specifically, the stepped hole further includes a spring mounting hole recessed inward, and communicates with the second hole. The through hole in the fixing block 13 may also be in the form of a stepped hole as shown in fig. 6, where the stepped hole includes a spring mounting hole located at the outer side and a fixing hole located at the inner side of the spring mounting hole, the fixing hole is generally provided with an internal thread, and one end of the guide shaft 33 is provided with an external thread and is matched with the internal thread in the fixing hole to fix one end of the guide shaft 33. Of course, in practical applications, the fixing between the one end of the guide shaft 33 and the fixed block 13 may be realized by other methods, and the structure of the through hole in each suction block may be appropriately adjusted according to actual needs as long as the structure of the through hole can conveniently realize the mutual movement between the N suction blocks.

In practical applications, the first driving device 3 further includes a first slider driving device 31, the first slider driving device 31 is connected to the first adsorption block and the nth adsorption block, and the first slider driving device 31 drives the first adsorption block and the nth adsorption block to move to a predetermined separation position or drives the first adsorption block to the nth adsorption block to adhere to each other.

In this way, the first adsorption block and the nth adsorption block in each row move under the driving of the first slide block driving device 31, and the rest adsorption blocks move mutually under the action of the elastic element 32, so that the thin film in each row is divided into N truly independent single sheets, and the structure is simple and the cost is low.

The first slider driving device 31 and the second slider driving device 41 may be air cylinders, hydraulic cylinders, or motors, and the selection is specifically performed according to actual needs. When the first slider driving device 31 and the second slider driving device 41 both adopt cylinders, power connection does not need to be considered, and the adsorption blocks can move mutually by adopting a simple starting mode, so that the use requirement of equipment is greatly simplified, and the cost is saved. For example, the first sliding driving device 31 shown in fig. 6 is an air cylinder, and both ends of the air cylinder are fixedly connected to the bottoms of the first adsorption block and the nth adsorption block, respectively, so that the first adsorption block and the nth adsorption block move relative to each other through the movement of the piston rod of the air cylinder.

In order to make the sliding blocks 14 on both sides of the fixed block 13 move smoothly, two limit blocks 23 are arranged on the supporting frame 2, and the two limit blocks 23 respectively limit both ends of the first sliding block driving device 31.

In another embodiment of the present application, referring to fig. 10, the first driving device 3 includes an elastic member 32, at least one of the X rows of suction blocks includes a fixed block 13 fixedly connected to the supporting frame 2 and a sliding block 14 located on at least one side of the fixed block 13, and the sliding block 14 is slidably connected to the supporting frame 2. An elastic part 32 is arranged between any two adsorption blocks in at least one row of the X rows of adsorption blocks, and the adsorption blocks are driven to be separated through the elastic part 32.

Therefore, the N adsorption blocks can move mutually by compressing and bouncing off the elastic piece 32, and the device has the advantages of simple structure, simple and convenient operation and low cost.

Specifically, the first driving device 3 further includes a sliding shaft 34, the elastic element 32 is sleeved on the sliding shaft 34 between the two adsorption blocks, the sliding shaft 34 passes through the through holes of the N adsorption blocks, and after passing through the through holes, two ends of the sliding shaft 34 are respectively fixedly connected with the support frame 2. The sliding shaft 34 also plays a role of guiding, one adsorption block on the outermost side of the N adsorption blocks is the fixed block 13, and the rest adsorption blocks on one side of the fixed block 13 are the sliding blocks 14. In practical applications, each suction block is further provided with a spring mounting hole for mounting the elastic member 32, so as to facilitate the mounting of the elastic member 32.

In practical applications, the first driving device 3 further includes a first slider driving device 31, a sliding block 14 is disposed on one side of the fixed block 13, and the fixed block 13 and the sliding block 14 farthest from the fixed block 13 move relative to each other under the driving of the first slider driving device 31.

In this way, the fixed block 13 and the outermost slide block 14 are driven by the first slide block driving device 31 to move, and the other middle adsorption blocks move mutually under the action of the elastic element 32, so that the thin film in each row is divided into N truly independent single sheets, and the structure is simple and the cost is low.

For example, the first slider driving device 31 shown in fig. 10 is an air cylinder, and both ends of the air cylinder are fixedly connected to the bottom of the fixed block 13 and the bottom of the outermost slider 14, respectively, so that the fixed block 13 and the outermost slider 14 are separated from each other by the movement of the piston rod of the air cylinder. In addition, in the concrete implementation process, the support frame 2 is generally provided with a limit block 23 to limit the bottom of the cylinder and prevent the bottom of the cylinder from retreating.

In practical applications, any one of the N rows of suction blocks may be arranged according to the structural manner shown in fig. 6, or may be arranged according to the structural manner shown in fig. 10, and the structural manners of the rows of suction blocks may be arbitrarily combined according to the two manners described above, or may be arranged according to other structural manners, as long as the manner that the plurality of suction blocks can move relative to each other through the action of the elastic member 32 is implemented, which is only an example and is not limited in this embodiment.

Further, taking the example that the adsorption device 1 shown in fig. 2 includes two rows of adsorption blocks, namely a first row of adsorption blocks 11 and a second row of adsorption blocks 12, and the two first slider driving devices 31 are both X-axis cylinders, and the two X-axis cylinders are disposed in parallel and in the same direction, and the second slider driving device 41 is a Y-axis cylinder.

In a specific implementation process, the support frame 2 generally includes a first support frame 21 and a second support frame 22, at least one adsorption block in the first row of adsorption blocks 11 is slidably connected to the first support frame 21, one of the X-axis cylinders is disposed at the bottom of the first row of adsorption blocks 11, the first support frame 21 includes two first optical axes 211 and a bottom plate 212 located below the X-axis cylinders, the two first optical axes 211 are symmetrically disposed along two sides of the guide shaft 33, and one of the two first optical axes 211 plays a role in guiding the adsorption blocks to slide, and the other role in enhancing the stability of the adsorption blocks during movement.

At least one of the second row of adsorption blocks 12 is slidably connected to the second support frame 22, another X-axis cylinder is disposed at the bottom of the second row of adsorption blocks 12, the second support frame 22 includes two second optical axes 221, a connection plate (not shown in the figure) located below the X-axis cylinder, and a support 222 for being placed on the worktable, and two ends of the two second optical axes 221 and two ends of the connection plate are respectively fixed to the two support 222.

One end of the Y-axis cylinder is fixedly connected to the bottom plate 212, and the other end of the Y-axis cylinder is fixedly connected to the connecting plate, when the Y-axis cylinder is used, the second support frame 22 is fixed, and the first support frame 21 starts to move under the driving of the Y-axis cylinder, so as to separate the first row of adsorption blocks 11 from the second row of adsorption blocks 12.

More specifically, in order to better understand the scheme of the above-described embodiment, the process of implementing the mutual separation of the ten adsorption blocks is specifically described below by taking an example in which each row of adsorption blocks shown in fig. 3 and 6 to 8 includes five adsorption blocks, and the five adsorption blocks 1 shown in fig. 7 are taken as a first block, a second block, a third block, a fourth block, and a fifth block in order from left to right. The separation process is as follows:

in the initial starting state, the whole device is not connected with an air source, the two X-axis cylinders and the Y-axis cylinder are both at the zero position of the cylinder piston rod, and the elastic piece 5 is in a compressed state.

When the whole device enters a state of cutting the film, the air source is firstly connected, the vacuum generator generates vacuum, air is introduced into the vacuum channel 16 through the quick-connection plug 17, vacuum negative pressure is formed in the adsorption area, and the film is tightly attached to the adsorption surface under the action of vacuum adsorption force.

Next, the whole film is divided into two parts, and referring to fig. 3, the Y-axis cylinder extends forward to drive five adsorption blocks in the first row of adsorption blocks 11 to move forward, so as to realize the process of dividing into two parts.

Then, the film of each row is divided into five, and the method comprises the following three steps:

the first step is as follows: referring to fig. 7, the piston rods of the two X-axis cylinders extend out simultaneously to drive the first block to move forward, and when the piston rods touch one of the limiting blocks 23 on the first supporting frame 21, the piston rods cannot move forward.

The second step is that: referring to fig. 7, the third block is a fixed block 13, and in the whole process of dividing the film, the third block is fixed, after the piston rod of the X-axis cylinder drives the first block to move forward, the internal elastic element 32 extends out, and the second block and the fourth block extend out for a certain distance under the reaction force of the elastic element 32 until the second block and the fourth block touch the limit step of the guide shaft 33, and the stroke of the elastic element 32 is finished. Since the first and second steps are almost synchronously performed, they are shown in the same fig. 7.

The third step: the piston rod of the X-axis cylinder can not move forward when touching one of the limiting blocks 23, and the stroke of the X-axis cylinder is not completed, so that the cylinder body of the X-axis cylinder moves in the opposite direction of the piston rod to drive the fifth block until touching the other limiting block 23 of the first supporting frame 21, and the stroke of the X-axis cylinder is completed. At the moment, the five adsorption blocks in each row are separated from each other, the film in each row is divided into five parts, and then the whole film is divided into ten truly independent single sheets. And then the piston rod and the cylinder body of the X-axis cylinder start to reset and retract, and simultaneously the Y-axis cylinder also starts to reset and retract.

Of course, the above-mentioned process for dividing the thin film into truly independent individual pieces is only an example, and the specific dividing process depends on the number and arrangement of the actual adsorption blocks and the specific structural form of the rest of the components, which is not limited in this application.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical substance of the present invention still belong to the protection scope of the technical solution of the present invention.
