[0002] In current production of solar cells, laser scribing technology is widely used to improve production efficiency or meet specific requirements. This technology divides a complete cell into two half-cells. However, this division operation generates unpassivated sheet cross-sections, resulting in an increase in the recombination rate at the edges of the sheet cross-sections, and thus reducing the photoelectric conversion efficiency by approximately 0.2%-0.3%. To solve this problem, it is necessary to perform a passivation coating treatment on the cut sheets. The process of performing a passivation coating treatment on the cut sheets requires the use of a drawer-type cassette as a carrier.

[0033] Next, in combination with the accompanying drawings in the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0034] Next, in combination with Figures 1 to 8 the jacking device 400 of this embodiment will be described.

[0035] As Figures 1 to 4 shown, the jacking device 400 of this embodiment is applied to the sheet transfer device 10. The sheet transfer device 10 has a loading station, and the loading station is a station where the sheet transfer device 10 stacks sheets and places them into the magazine 300. The sheet transfer device 10 includes a handling device 100 and a tray 200.

[0036] The tray 200 is used to support the magazine 300, and the handling device 100 is used to move the magazine 300 away from the loading station or move the magazine to the loading station. For example, the loading station is arranged at one end of the handling device 100. When sheets need to be loaded, the empty magazine 300 is moved to the loading station through the handling device 100, so that the sheets are stacked at the loading station. After the sheets are loaded, the full magazine 300 is moved to the next station through the handling device 100.

[0037] In one embodiment, the handling device 100 can be a conveying mechanism. The conveying mechanism is connected to the tray 200. When the tray 200 supports the magazine 300, driving the tray 200 to move by the conveying mechanism can drive the magazine 300 to move. The conveying mechanism transports the tray 200 to the loading station. After filling the magazine 300 with sheets, the tray 200 is transported to the loading station, and then the full magazine is transported to the next station.

[0038] In other embodiments, the handling device 100 can also be a manipulator, a clamping mechanism, etc. The handling of the magazine is completed by the manipulator. For example, the empty magazine 300 is moved to the loading station by the manipulator, and after the sheets are loaded, the full magazine 300 is moved to the next station by the manipulator.

[0039] The tray 200 has a first through hole 201, and the first through hole 201 penetrates the tray 200 in the vertical direction.

[0040] The upper side of the material box 300 has a feed inlet 301, and the sheet 700 can enter the material box 300 through the feed inlet 301. The bottom of the material box 300 has a second through hole 302. When the tray 200 supports the material box 300, the second through hole 302 is vertically aligned with the first through hole 201. In this embodiment, the shapes and sizes of the second through hole 302 and the first through hole 201 are not specifically limited, and the shapes and sizes of the second through hole 302 and the first through hole 201 may be the same or different. For example, the second through hole 302 is a rectangular hole, the first through hole 201 is an oval hole, and the size of the second through hole 302 is larger than that of the first through hole 201. When the tray 200 supports the material box 300, the positive projections of the second through hole 302 and the first through hole 201 on the same horizontal plane at least partially overlap. Preferably, the sizes and shapes of the first through hole 201 and the second through hole 302 are the same, and when the tray 200 supports the material box 300, the positive projections of the first through hole 201 and the second through hole 302 on the same horizontal plane coincide. It should be noted that the coincidence of the positive projections of the first through hole 201 and the second through hole 302 on the same horizontal plane means that the positive projection of one of the first through hole 201 and the second through hole 302 is located within the positive projection of the other, or the edges of the positive projections of the first through hole 201 and the second through hole 302 coincide.

[0041] Combined with Figure 5 and Figure 6 , the lifting device 400 includes a support assembly 410. The support assembly 410 is located at the loading station, and when the tray 200 is at the loading station, the support assembly 410 is located below the first through hole 201 and is vertically aligned with the first through hole 201.

[0042] The lifting device 400 further includes a lifting drive assembly 420. The lifting drive assembly 420 is connected to the support assembly 410 and is configured to drive the support assembly 410 to lift and lower, so that when the tray 200 supports the material box 300 and is at the loading station, the support assembly 410 passes through the first through hole 201 and the second through hole 302 and supports the sheet 700 entering the material box 300 through the feed inlet 301 to descend.

[0043] Specifically, when the handling device 100 drives the cartridge 300 to move through the tray 200, the support assembly 410 is in a lower position driven by the lifting drive assembly 420 to avoid the support assembly 410 blocking the movement of the tray 200 and the cartridge 300. When the tray 200 supports the cartridge 300 and is located at the loading station, the support assembly 410 can be driven by the lifting drive assembly 420 to rise to a position passing through the first through hole 201 and the second through hole 302. At this time, the sheet 700 is placed into the cartridge 300 from the feed port 301, and the upper end of the support assembly 410 supports the sheet 700 to prevent the sheet 700 from directly falling and being damaged. Then, by driving the support assembly 410 to descend through the lifting drive assembly 420, the sheet 700 can be lowered. It can be seen that through the lifting device 400 of this embodiment, the sheet 700 can be ensured to stably enter the drawer-type cartridge 300 when loading the sheet 700, improving the stability of the sheet 700 when entering the drawer-type cartridge 300, which is beneficial to improving the yield rate and production efficiency.

[0044] In some embodiments of the present disclosure, the support assembly 410 includes a support rod 411 and a support member 412. The support rod 411 extends vertically, and the bottom end of the support rod 411 is connected to the lifting drive assembly 420. The cross-sectional shape of the support rod 411 can be circular, rectangular, triangular, polygonal, elliptical, etc. Preferably, the cross-section of the support rod 411 is circular. Since the support rod 411 plays a role in support and stability, preferably, the support rod 411 is made of a metal material.

[0045] The support member 412 is fixedly connected to the top end of the support rod 411 and is used to contact the sheet 700 in the cartridge 300. Optionally, the support member 412 extends in the horizontal direction, and the upper side of the support member 412 is preferably a planar structure, so as to increase the contact area between the support rod 411 and the sheet 700 and prevent the sheet 700 from being locally stressed too much. When the tray 200 supports the cartridge 300 and is located at the loading station, the support rod 411 and the support member 412 are aligned with the first through hole 201 and the second through hole 302 in the vertical direction.

[0046] The alignment of the above-mentioned support rod 411 and the supporting member 412 with the first through hole 201 and the second through hole 302 in the vertical direction means that on the same horizontal plane, the orthographic projections of the support rod 411 and the supporting member 412 are located within the first through hole 201 and the second through hole 302, or the edges of the orthographic projections of the support rod 411 and the supporting member 412 coincide with the edges of the orthographic projections of the first through hole 201 and the second through hole 302. Preferably, the orthographic projection size of the supporting member 412 on the horizontal plane is smaller than the orthographic projection sizes of the first through hole 201 and the second through hole 302 on the horizontal plane, so that the supporting member 412 can smoothly pass through the first through hole 201 and the second through hole 302. It should be noted that the shapes of the orthographic projections of the support rod 411 and the supporting member 412 on the horizontal plane may be the same as or different from the shapes of the orthographic projections of the first through hole 201 and the second through hole 302, and no specific limitation is made here, as long as when the support rod 411 and the supporting member 412 are aligned with the first through hole 201 and the second through hole 302 in the vertical direction, it is allowed for the support rod 411 and the supporting member 412 to vertically pass through the first through hole 201 and the second through hole 302.

[0047] Optionally, the supporting member 412 includes an elastic member. For example, the supporting member 412 is entirely made of an elastic material, or the upper surface of the supporting member 412 has an elastic layer of elastic material. The above-mentioned elastic material can be a rubber material, etc. The elastic contact between the supporting member 412 and the sheet 700 can reduce the risk of damage to the sheet 700.

[0048] Optionally, the supporting member 412 and the support rod 411 are detachably connected. For example, a plugging blind hole is provided on the lower side of the supporting member 412, and the support rod 411 is detachably plugged and fixed to the supporting member 412 through this plugging blind hole. Thus, when the supporting member 412 is worn during long-term use, it is convenient to replace the support.

[0049] Optionally, the support assembly 410 includes a plurality of support rods 411. The bottom ends of the plurality of support rods 411 are respectively connected to the lifting drive assembly 420, and the top ends of the plurality of support rods 411 are respectively fixedly connected to the supporting member 412. For example, the number of support rods 411 is two, the two support rods 411 have the same height, and the two support rods 411 are arranged at intervals along the length direction of the supporting member 412. By connecting the supporting member 412 with a plurality of support rods 411 together, the stability of the supporting member 412 can be ensured and shaking can be prevented.

[0050] In some embodiments of the present disclosure, the number of the support assemblies 410 is multiple, and the top ends of the multiple support assemblies 410 have the same height. The multiple support assemblies 410 can be lifted and lowered synchronously under the drive of the lifting drive assembly 420, and moreover, the multiple support assemblies 410 can be simultaneously inserted into the first through hole 201 and the second through hole 302 to jointly support the sheet 700.

[0051] Optionally, the tray 200 is provided with a plurality of first through holes 201, the bottom of the cartridge 300 is provided with a plurality of second through holes 302, the plurality of first through holes 201 and the plurality of second through holes 302 correspond to each other one by one, and each support assembly 410 corresponds to one first through hole 201 and one second through hole 302. Each support assembly 410 is respectively adapted to be inserted into the corresponding first through hole 201 and second through hole 302, thereby avoiding an overly large size of a single first through hole 201 or second through hole 302.

[0052] In some embodiments of the present disclosure, the sheet transfer device 10 further includes a frame 500. The lifting drive assembly 420 includes a connecting frame 421, a first motor 422, a first lead screw, a first nut, and a lifting frame 423. The connecting frame 421 is used for fixedly connecting with the frame 500. The first motor 422 includes an output shaft, the first motor 422 is fixedly connected with the connecting frame 421, the first lead screw is rotatably connected with the connecting frame 421 and is in transmission connection with the output shaft, the first nut is threadedly connected with the first lead screw, the lifting frame 423 is slidably connected with the connecting frame 421 and is respectively fixedly connected with the support assembly 410 and the first nut. The sliding direction of the lifting frame 423 is along the vertical direction.

[0053] Among them, the frame 500 can be any structure such as a plate shape, a box shape, or a frame, and no specific limitation is made here. The frame 500 is located below the handling device 100. The frame 500 can be provided with through holes or grooves to avoid blocking the lifting of the support assembly 410. The top end of the connecting frame 421 is fixedly connected with the frame 500 to achieve position fixation. The first motor 422 can be installed at the lower end of the connecting frame 421. The output shaft of the first motor 422 and the first lead screw are in transmission connection through structures such as a coupling, a gear set, or a synchronous belt. When the first motor 422 operates, it drives the first lead screw to rotate axially, thereby driving the first nut to lift. During the lifting process of the first nut, it drives the lifting frame 423 and the support assembly 410 to lift.

[0054] In this embodiment, the connection between the frame 500 and the connecting frame 421 can ensure the stability of the lifting device 400, and the support assembly 410 and the lifting drive assembly 420 can be arranged below the handling device 100 to facilitate the realization of the lifting function. In addition, the driving structure of the first motor 422, the first lead screw, and the first nut can accurately control the lifting height of the support assembly 410.

[0055] Optionally, the lifting drive assembly 420 further includes at least one slide rail. The slide rail extends in the vertical direction and is fixedly connected to the connecting frame 421. The slider is slidably connected to at least one slide rail and is fixedly connected to the lifting frame 423. For example, the number of slide rails is two, and the two slide rails are located on the same side of the connecting frame 421. The slider is slidably connected to the two slide rails at the same time and is fixedly connected to the lifting frame 423. By providing the slide rails and the slider, the lifting of the lifting frame 423 can be made more stable, preventing the support assembly 410 from shaking.

[0056] Combined with Figure 1 , Figure 2 and Figure 4 , in some embodiments of the present disclosure, the jacking device 400 further includes a rectifying assembly 600. The rectifying assembly 600 is located at the loading station, and when the tray 200 supports the cartridge 300 and is located at the loading station, the rectifying assembly 600 is located above the cartridge 300.

[0057] Combined with Figure 7 and Figure 8 , the rectifying assembly 600 includes a mounting frame 610, a drive source, a first limiting member 620, a first pushing structure 630, a second limiting member 640, and a second pushing structure 650. The mounting frame 610 is fixedly connected to the frame body 500 through structures such as columns. The mounting frame 610 has a third through hole 611 arranged vertically, and the third through hole 611 is configured to allow the sheet 700 to pass through. The first limiting member 620 is fixedly connected to the mounting frame 610. The second limiting member 640 is fixedly connected to the mounting frame 610. The drive source is arranged on the mounting frame 610. The first pushing structure 630 is arranged on the mounting frame 610, the first pushing structure 630 is connected to the drive source, and the pushing direction of the first pushing structure 630 faces the first limiting member 620. The second pushing structure 650 is arranged on the mounting frame 610, the second pushing structure 650 is connected to the drive source, and the pushing direction of the second pushing structure 650 faces the second limiting member 640. The first limiting member 620 and the first pushing structure 630 are respectively disposed on two opposite sides of the third through hole 611, and the second limiting member 640 and the second pushing structure 650 are respectively disposed on the other two opposite sides of the third through hole 611.

[0058] Optionally, the pushing direction of the first pushing structure 630 is perpendicular to the pushing direction of the second pushing structure 650. For example, the pushing direction of the first pushing structure 630 is parallel to the conveying direction of the handling device 100, and the pushing direction of the second pushing structure 650 is perpendicular to the conveying direction of the handling device 100.

[0059] The driving source can drive the first pushing structure 630 and the second pushing structure 650 to operate. Through the cooperation between the first pushing structure 630 and the first limiting member 620 and the cooperation between the second pushing structure 650 and the second limiting member 640, the rectification of the sheet 700 can be realized, so that the sheet 700 is aligned with the third through hole 611 and the feeding port 301 in the vertical direction, ensuring the accurate position of the sheet 700 and enabling it to smoothly pass through the third through hole 611 and the feeding port 301 and enter the cartridge 300.

[0060] Optionally, the driving source includes a second motor 631. The second motor 631 is fixedly connected to the mounting bracket 610, and the motor shaft of the second motor 631 is respectively connected to the first pushing structure 630 and the second pushing structure 650.

[0061] Optionally, the first pushing structure 630 includes a first synchronous belt assembly 632, a first cam 633, a first pusher 634 and a first elastic reset member 635. The output shaft of the second motor 631 is connected to the first cam 633 through the first synchronous belt assembly 632. The first cam 633 is rotatably connected to the mounting bracket 610. The first pusher 634 is slidably connected to the mounting bracket 610 and is disposed opposite to the first limiting member 620. The first pusher 634 is located on the side of the first cam 633 close to the first limiting member 620. The first elastic reset member 635 can be a tension spring, a compression spring or an elastic sheet, etc. The first elastic reset member 635 connects the mounting bracket 610 and the first pusher 634 and is configured to provide an elastic force away from the first limiting member 620 to the first pusher 634. When the second motor 631 operates, the first cam 633 is driven to rotate through the first synchronous belt assembly 632. When the convex portion of the first cam 633 rotates towards the first pusher 634, the first pusher 634 is squeezed, enabling the first pusher 634 to slide towards the direction close to the first limiting member 620 and cooperate with the first limiting member 620 to realize the rectification of the sheet 700. When the first cam 633 continues to rotate until the convex portion gradually moves away from the first pusher 634, the first pusher 634 is reset under the elastic force of the first elastic reset member 635 and moves away from the first limiting member 620, preparing for the next rectification of the sheet 700.

[0062] Optionally, the first pushing structure 630 further includes at least one first guide shaft 636 and at least one first linear bearing 637. The first guide shaft 636 is slidably connected to the mounting bracket 610 through the first linear bearing 637, and the first pusher 634 is fixedly connected to one end of the first guide shaft 636. The sliding connection between the first pusher 634 and the mounting bracket 610 can be realized through the first guide shaft 636, and the stability of the first pusher 634 during movement can be ensured.

[0063] Optionally, the second pushing structure 650 includes a second synchronous belt assembly 652, a second cam 653, a second pushing member 654, and a second elastic reset member 655. The output shaft of the second motor 631 is connected to the second cam 653 through the second synchronous belt assembly 652. The second cam 653 is rotatably connected to the mounting bracket 610. The second pushing member 654 is slidably connected to the mounting bracket 610 and is disposed opposite to the second limiting member 640. The second pushing member 654 is located on the side of the second cam 653 close to the second limiting member 640. The second elastic reset member 655 can be a tension spring, a compression spring, an elastic sheet, etc. The second elastic reset member 655 connects the mounting bracket 610 and the second pushing member 654 and is configured to provide an elastic force to the second pushing member 654 away from the second limiting member 640. When the second motor 631 operates, the second cam 653 is driven to rotate through the second synchronous belt assembly 652. When the convex portion of the second cam 653 rotates towards the second pushing member 654, the second pushing member 654 is squeezed, so that the second pushing member 654 can slide towards the direction close to the second limiting member 640, and cooperate with the second limiting member 640 to realize the alignment of the sheet 700. When the second cam 653 continues to rotate until the convex portion gradually moves away from the second pushing member 654, the second pushing member 654 is reset under the elastic force of the second elastic reset member 655 and moves away from the second limiting member 640, preparing for the next alignment of the sheet 700.

[0064] Optionally, the second pushing structure 650 further includes at least one second guiding shaft 656 and at least one second linear bearing 657. The second guiding shaft 656 is slidably connected to the mounting bracket 610 through the second linear bearing 657. One end of the second pushing member 654 is fixedly connected to the second guiding shaft 656. The sliding connection between the second pushing member 654 and the mounting bracket 610 can be realized through the second guiding shaft 656, and the stability of the second pushing member 654 during movement can be ensured.

[0065] In some other embodiments, the driving source includes a gas source such as an air pump or an air storage tank. The first pushing structure 630 includes a first cylinder, and the second pushing structure 650 includes a second cylinder. The gas source is respectively connected to the first cylinder and the second cylinder. The alignment of the sheet 700 is jointly realized through the cooperation of the first cylinder and the first limiting member 620 and the cooperation of the second cylinder and the second limiting member 640.

[0066] The process of rectifying the rectifying component 600 can be carried out when the supporting component 410 supports the sheet 700. Specifically, the supporting component 410 can rise to a position passing through the feeding port 301. When the handling device 100 conveys the sheet 700 to the position of the rectifying component 600, the sheet 700 is placed on the supporting component 410, and the sheet 700 is supported by the supporting component 410. At this time, the rectifying component 600 operates, and the sheet 700 can be placed in a correct position, so that the supporting component 410 can support the sheet 700 to smoothly pass through the feeding port 301 and enter the cartridge 300.

[0067] Combined with Figures 1 to 4 , the embodiment of the present disclosure further provides a sheet transfer device 10. The sheet transfer device 10 has a loading station. The sheet transfer device 10 includes a tray 200, a handling device 100, and the above-mentioned lifting device 400. The tray 200 has a first through hole 201; the handling device 100 is configured to move the cartridge 300 away from the loading station or to move the cartridge 300 to the loading station. The supporting component 410 of the lifting device 400 is located at the loading station, and when the tray 200 is located at the loading station, the supporting component 410 is located below the first through hole 201.

[0068] Optionally, the handling device may be a conveying mechanism. The conveying mechanism is connected to the tray 200 and is configured to drive the tray 200 to move so as to move the sheet away from the loading station. The conveying path of the conveying mechanism passes through the loading station. The conveying mechanism may include a third motor, a second lead screw, and a second nut. The third motor is fixed to the frame 500, the second lead screw is rotatably connected to the frame 500, the second nut is threadedly connected to the second lead screw, is slidably connected to the frame 500, and is fixed to the tray 200. When the third motor operates, the tray 200 can be driven to move horizontally in a straight line through the second lead screw and the second nut.
