Description

Technical Field

[0001] This utility model belongs to the technical field of material conveying equipment, and relates to a longitudinal transfer mechanism, specifically a longitudinal transfer mechanism for materials in a perovskite battery coating crystallization annealing furnace. Background Technology

[0002] Perovskite solar cells (i.e., perovskite-type solar cells) are thin-film solar cells that use perovskite-type organometal halide semiconductors as photoelectric conversion materials. They generally include a substrate, a conductive material layer, a first carrier transport layer, a perovskite layer, a second carrier transport layer, a top electrode layer, etc. The materials on the substrate can be defined as the coating layers of the perovskite solar cell.

[0003] Chinese invention patent application number 202310768743.2 discloses a perovskite solution coating equipment and method, which is configured according to the product processing sequence, including an ultrasonic cleaning mechanism for cleaning the product, a laser scribing mechanism for scribing lines, and a mechanism for spraying NiO. x The system includes a magnetron sputtering mechanism, a laser-guided spraying mechanism for spraying perovskite solution, a vacuum crystallization mechanism for crystallizing the product after spraying perovskite solution, an annealing mechanism for activating perovskite, a vapor deposition mechanism for vapor deposition of the product, a laser edge cleaning mechanism for edge cleaning of the product, and an encapsulation and lamination mechanism for encapsulation and lamination of the product. It also includes a transfer mechanism for transferring the product between these mechanisms. This transfer mechanism comprises a first transfer mechanism, a second transfer mechanism, a third transfer mechanism, a fourth transfer mechanism, and a fifth transfer mechanism. The first transfer mechanism is used to transfer the product between the ultrasonic cleaning mechanism and the laser scribing mechanism, and between the ultrasonic cleaning mechanism and the magnetron sputtering mechanism… This transfer mechanism relies on a robotic arm for material transfer, which is clearly unsuitable for transferring large-sized (e.g., larger than 2000mm x 1000mm) perovskite solar cells (or substrates), and large-sized perovskite solar cells are easily damaged during the receiving and transfer process.

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0023] like Figures 1 to 3 The longitudinal material transfer mechanism 3 of the perovskite battery coating crystallization annealing furnace shown mainly includes a supporting unit 31, a transfer tooling 32, and a material conveying unit 35.

[0024] The support unit 31 includes two parallel and spaced hollow support frames 311 (these two hollow support frames 311 can be installed on other structures to realize the installation or fixation of the longitudinal material transfer mechanism 3 of the entire perovskite battery coating crystallization annealing furnace), a first sprocket 312 rotatably installed at either end of the two hollow support frames 311 (i.e., there are two first sprockets 312, which are respectively installed at the same end of the two hollow support frames 311 and located inside the hollow support frame 311; the rotatability can be achieved using existing conventional methods, such as installing the mounting shaft inside the hollow support frame 311 through a bearing, and then installing the first sprocket 312 on the mounting shaft; the same applies below), and a sprocket drive rod 313 rotatably installed at the other end of the two hollow support frames 311 and having a second sprocket (the first sprocket is the first sprocket). There are two sprockets, each located within one of the two hollow support frames 311; a sprocket drive rod motor 316 connected to the end of the sprocket drive rod 313 to drive its rotation (so that when the sprocket drive rod motor 316 is working, it can drive the sprocket drive rod 313 to rotate, thereby ensuring that the two second sprockets on it rotate synchronously); a transmission chain 314 mounted on the first sprocket 312 and the second sprocket and located within the hollow support frame 311 (there are also two transmission chains 314, which are mounted one-to-one on the first sprocket 312 and the second sprocket); and a plurality of rolling wheels 315 rotatably mounted on the transmission chain 314 and arranged sequentially (the plurality of rolling wheels 315 are divided into two groups and densely distributed on the entire transmission chain 314), with at least some of the rolling wheels 315 protruding from the upper surface of the hollow support frame 311. Thus, when the sprocket drive rod motor 316 is working, it can drive the rotation of the transmission chain 314, thereby driving the transmission tooling 32 to slide horizontally on the support unit 31.

[0025] The transmission fixture 32 includes a load-bearing base frame movably mounted on the support unit 31 (i.e., the load-bearing base frame is supported on several aforementioned rolling wheels 315; when the transmission chain 314 rotates, the load-bearing base frame can be moved relative to the support unit 31 via the rolling wheels 315), limiting plates 326 installed at the four corners of the load-bearing base frame (i.e., there are four limiting plates 326 located at the four corners of the load-bearing base frame; typically, at least two adapter blocks are installed on the bottom surface of each limiting plate 326, thereby mounting the limiting plate 326 onto the load-bearing base frame via the adapter blocks), and multiple limiting rods 327 connecting adjacent limiting plates 326 (since the load-bearing base frame is relatively large in the lateral direction (i.e., in the length direction), in order to ensure the straightness of the limiting rods 327, the limiting rods 327 in this direction can be...). 27 is configured as two rods. At this time, one end of the limiting rod 327 is connected to the corresponding limiting plate 326, and the other end is installed on the bearing base frame through another adapter block. The limiting protrusion 328 (there are multiple limiting protrusions 328, eight in this embodiment, which cooperate with the limiting rod 327 to form a substrate accommodating space that matches the perovskite solar cell, so that the perovskite solar cell can be positioned by the accommodating space after being moved in) and multiple material receiving heads 320 installed on the bearing base frame (these material receiving heads 320 are located in the substrate accommodating space, and the multiple material receiving heads 320 cooperate with the multiple limiting protrusions 328 to support the perovskite solar cell, so that the perovskite solar cell is in a flat state). In this embodiment, at least the limiting protrusion 328 and the receiving head 320 are made of polyetheretherketone (PEEK) independently, so that the perovskite solar cell will not be damaged when it comes into contact with them, thereby improving the quality and yield of the perovskite solar cell. It is also preferable to embed at least one bearing pad (not shown in the figure) on each limiting rod 327 to cooperate with the receiving head 320 and the limiting protrusion 328. The bearing pad is also made of polyetheretherketone, further improving the bearing effect of the perovskite solar cell. Specifically, the load-bearing frame includes side connecting rods 321 slidably mounted on a hollow support frame 311 via multiple rolling wheels 315, multiple first connecting crossbars 323 connected between two side connecting rods 321 and spaced apart (in this embodiment, a limiting plate 326 is mounted on the two outermost first connecting crossbars 323 via two adapter blocks), positioning blocks 324 mounted at both ends of each first connecting crossbar 323, at least two second connecting vertical rods 322 penetrating multiple positioning blocks 324 and perpendicular to the first connecting crossbars 323, and connecting reinforcing rods 325 connecting multiple first connecting crossbars 323 and perpendicular to them. Multiple material bearing heads 320 are spaced apart and mounted on the connecting reinforcing rods 325. This arrangement ensures the strength of the entire load-bearing frame and prevents it from falling apart during back-and-forth movement, thereby ensuring its service life.

[0026] The material conveying unit 35 is installed in the conveying fixture 32 in a height-adjustable manner via the lifting unit 34, and is used to input or output material 1' (i.e., titanium dioxide solar cell or substrate); the material conveying unit 35 has two states: when it is in the raised state, the material conveying unit 35 is higher than the conveying fixture 32; when it is in the lowered state, the material conveying unit 35 is lower than the conveying fixture 32.

[0027] The aforementioned lifting unit 34 includes multiple base plates 341 spaced apart (preferably two base plates 341 spaced apart and parallel to each other and mounted on other structures to ensure the normal use of the conveying unit 35), multiple sets of guide sleeves 340 mounted on each base plate 341 (usually two sets, with two in each set; the same below), lifting plates 343 perpendicular to the base plates 341 and correspondingly inserted into the multiple sets of guide sleeves 340 via multiple guide rods 342, multiple cylinder carriers 344 mounted between two adjacent base plates 341, and lifting cylinders 345 mounted on each cylinder carrier 344 and connected to the corresponding lifting plates 343. The lifting plates 343 are connected to the conveying unit 35 (more specifically, connected to two support side plates 351). Thus, the lifting unit 34 can drive the lifting of the conveying unit 35. In this embodiment, the lifting unit 34 also includes multiple fixed connecting blocks 347 installed on the upper surface of each base plate 341 and cooperating with the guide sleeve 340, and multiple first reinforcing rods 346 connected to adjacent fixed connecting blocks 347, so as to improve the strength of the entire lifting unit 34 and improve the precision of its operation.

[0028] The material conveying unit 35 includes multiple support side plates 351 (two support side plates 351 arranged in parallel) installed on the lifting unit 34 and spaced apart; multiple first pulleys 352 rotatably mounted on the side wall of each support side plate 351 (usually mounted on the inner side wall of each support side plate 351); a drive shaft 354 rotatably passing through the multiple support side plates 351; and second pulleys 353 mounted on the drive shaft 354 and corresponding to the multiple first pulleys 352 (usually two second pulleys 353, one second pulley 353 corresponding to a set of first pulleys 352). The system includes pulleys 352, a conveyor belt 356 (two conveyor belts 356 are used for outputting or inputting material 1') wound around multiple first pulleys 352 and second pulleys 353, and a geared motor 355 mounted on any support side plate 351 and connected to the end of the drive shaft 354 (so that when the geared motor 355 is working, it can synchronously drive the rotation of the two second pulleys 353 through the drive shaft 354, and then drive the rotation of the two sets of first pulleys 352 through the conveyor belt 356, so that the material 1' on the conveyor belt 356 moves smoothly), with high precision. Each support side plate 351 has a first clearance groove 3511 at its lower part that cooperates with the lifting unit 34 (mainly to cooperate with the lifting plate 343 so that the lifting plate 343 is accommodated in the first clearance groove 3511, so as to prevent the lifting plate 343 from affecting the normal operation of the conveyor belt 356), and a second clearance groove 3512 at its upper part that cooperates with the bearing base frame (preferably, a tensioning wheel is provided on the inner wall of the support side plate 351 near the second clearance groove 3512 for the first pulley 352). The second pulley 353 cooperates with the corresponding conveyor belt 356 to avoid the first connecting crossbar 323. The second clearance groove 3512 mainly corresponds to the first connecting crossbar 323 so that the first connecting crossbar 323 can be accommodated in the second clearance groove 3512. In this way, when the conveyor unit 35 is raised and lowered under the action of the lifting unit 34, it will not be interfered with by the first connecting crossbar 323, thereby ensuring the normal and efficient operation of the longitudinal material transfer mechanism of the entire perovskite battery coating crystallization annealing furnace.

[0029] In this embodiment, to further ensure the accuracy of material conveying, the longitudinal material transfer mechanism of the perovskite battery coating crystallization annealing furnace also includes a centering unit 33. The centering unit 33 includes two sets of centering structures arranged opposite to each other. Each set of centering structures includes an extension 331 (such as a short profile) installed on the outer side of the support unit 31, a centering support frame 332 installed on the extension 331, a centering cylinder 333 installed on the centering support frame 332, a transition block 334 connected to the cylinder shaft of the centering cylinder 333, a first connecting rod 335 installed on the transition block 334 and with first centering heads 3351 installed at both ends, and a second connecting rod 336 connected to the transition block 334 and with second centering heads 3361 installed at both ends. The length of the second connecting rod 336 is greater than the length of the first connecting rod 335 and the second connecting rod 336 is located outside the first connecting rod 335. In this way, the operation of the centering cylinder 333 can drive the first connecting rod 335 and the second connecting rod 336 to move in opposite directions, thereby using the first centering head 3351 and the second centering head 3361 to make small and precise adjustments to the position of the material 1', so that it is in the precise center for subsequent transfer and other operations.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
