[0053] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work should fall within the scope of protection of this application.

[0054] At present, the laser scribing equipment for perovskite cells in the existing technology cannot guarantee the accuracy of the cell position during scribing, which affects the laser scribing accuracy and leads to a lower yield rate.

[0055] In order to solve the above problems, the applicant has developed a new type of alignment and regularization device, which can be applied to the laser scribing production line of perovskite cells. It is used to perform alignment and regularization operations on the perovskite before laser scribing to ensure that it is in a preset position, thereby improving the accuracy of subsequent laser scribing.

[0056] Specifically, see Figure 1 and Figure 2 , Figure 1 is a three-dimensional structural diagram of an embodiment of the alignment and regularization device of the present application, Figure 2 It is a schematic diagram of the top view of the structure of one embodiment of the alignment and regularization device of the present application.

[0057] like Figure 1 and Figure 2 As shown, the alignment and aligning device includes a conveying mechanism 100 , which is used to convey the workpiece, and an alignment station 200 is arranged on the conveying mechanism 100 .

[0058] When the alignment and regularization device is applied to a perovskite cell laser scribing production line, the workpiece may be a perovskite cell to be scribed, and the alignment station 200 may be a station for adjusting the position of the perovskite cell to be scribed.

[0059] Specifically, in the present embodiment, the conveying mechanism 100 adopts a conveying roller 101, which includes a plurality of conveying rollers 101 and a conveying wheel 102 arranged on the conveying roller 101, and the workpiece is driven to move by the rotating conveying wheel 102; in other embodiments, the conveying mechanism 100 may also adopt other types of conveying structures, such as drum type, belt type, etc., as long as they can realize the conveyance of the workpiece, and can achieve the effect of the present embodiment.

[0060] In this embodiment, four pushing mechanisms 300 are symmetrically arranged on both sides of the alignment station 200 in the first direction X. The four pushing mechanisms 300 are used to cooperate in adjusting the position of the workpiece in the first direction X, thereby achieving alignment and regularization operations.

[0061] Of course, in other embodiments, the number of pushing mechanisms 300 can also be adjusted based on specific working conditions. For example, a pushing mechanism 300 can be set on each side, or different numbers of pushing mechanisms 300 can be set on both sides of the alignment station 200, etc., all of which can achieve the effect of this embodiment.

[0062] The structure of the application push mechanism 300 is described in detail below. Figure 3 , Figure 3 It is a structural diagram of the push mechanism 300 of the present application.

[0063] like Figure 3 As shown, the pushing mechanism 300 includes a pushing member 301 and a first displacement unit 302, wherein the pushing member 301 is used to contact the edge of the workpiece, and the first displacement unit 302 is used to drive the pushing member 301 to move, so that the pushing member 301 can push the workpiece under the action of the first displacement unit 302 to adjust the position of the workpiece.

[0064] Specifically, in order to prevent the pushing member 301 from affecting the transmission of the workpiece, the pushing member 301 includes a rotatable bearing 3011, and the outer peripheral surface of the bearing 3011 is used to contact the edge of the workpiece.

[0065] The pushing member 301 further includes a mounting seat 3012 and a mounting column 3013 . The mounting seat 3012 is arranged at the working end of the first displacement unit 302 . The mounting column 3013 is arranged on the mounting seat 3012 , and the mounting column 3013 is extended along the thickness direction of the workpiece.

[0066] The bearing 3011 can be sleeved on the mounting column 3013 so that the bearing 3011 and the workpiece are in the same plane, which helps to improve the stability of the bearing 3011 pushing the workpiece.

[0067] Of course, in other embodiments, the bearing 3011 may also be installed in other ways, as long as the bearing 3011 can be rotatably installed, and the effect of this embodiment can be achieved.

[0068] The first displacement unit 302 of this embodiment can be a displacement element used to drive the bearing 3011 to move along the first direction X and vertically, so that the bearing 3011 can be adjusted to be at the same height as the workpiece and push the workpiece inward along the first direction X. At the same time, after the workpiece position adjustment is completed, the bearing 3011 can be retracted to below the conveying surface of the conveying mechanism 100 to avoid interference from other moving components when performing other operations on the workpiece.

[0069] Specifically, in this embodiment, the first displacement unit 302 includes a support base 3021 , a horizontal displacement element 3022 , and a vertical displacement element 3023 , and the support base 3021 is arranged on the frame 600 .

[0070] The horizontal displacement element 3022 is arranged on the support seat 3021, which includes a horizontal slider 3024, and the horizontal displacement element 3022 is used to drive the horizontal slider 3024 to move along the first direction X.

[0071] The vertical displacement element 3023 is arranged on the horizontal slider 3024 , and the vertical displacement element 3023 includes a vertical slider 3025 , and the vertical displacement element 3023 is used to drive the vertical slider 3025 to move vertically.

[0072] In this embodiment, the horizontal displacement element 3022 adopts a conventional screw nut structure, and the vertical displacement element 3023 adopts a conventional lifting cylinder structure. The specific structure will not be repeated. In other embodiments, other types of telescopic structures can also be used to achieve the effect of this embodiment.

[0073] Based on the pushing mechanism 300 of each embodiment described above, the alignment and regularization operation of the workpiece can be realized. In order to further improve the accuracy of the alignment and regularization, as Figure 1 and Figure 2 As shown, in this embodiment, an image acquisition mechanism 400 is arranged outside the corner of the alignment station 200. The image acquisition mechanism 400 is used to acquire images of the corners of the workpiece, and is also communicatively connected to a controller (not shown in the figure).

[0074] The controller may acquire the actual position of the workpiece based on the corner image of the workpiece, and control the pushing mechanism 300 to adjust the workpiece to the preset position based on the distance difference between the actual position of the workpiece and the preset position.

[0075] The controller may be a single chip microcomputer or a conventional control element such as a PLC controller, and both of them can achieve the effect of this embodiment.

[0076] It should be noted that the scheme in which the controller in this embodiment obtains the workpiece position based on the collected workpiece corner image and outputs motion instructions to the pushing mechanism 300 based on the workpiece position is a conventional control scheme in the field and is not the main invention of this application.

[0077] Specifically, see Figure 4 , Figure 4 It is a structural diagram of an embodiment of the image acquisition mechanism 400 of the present application.

[0078] like Figure 4 As shown, the image acquisition mechanism 400 includes a second displacement unit 401, which is arranged outside the corner of the alignment workpiece, and includes a slide plate 4011, and the second displacement unit 401 can drive the slide plate 4011 to move along the X, Y, and Z axes.

[0079] A camera fixing frame 402 is installed on the slide plate 4011 , a camera 403 is installed on the camera fixing frame 402 , and a shooting end of the camera 403 is set to point toward the workpiece.

[0080] It can be understood that the position of the camera 403 can be adjusted by the second displacement unit 401, so that the field of view of the camera 403 is adjusted to the corner of the workpiece, thereby realizing the collection of images at the corner of the workpiece.

[0081] In this embodiment, the second displacement unit 401 is a manual three-axis slide. In other embodiments, the second displacement unit 401 may also be other structures that can achieve three-axis motion, and the effect of this embodiment can be achieved.

[0082] In order to achieve rough positioning of the workpiece when it moves to the alignment station 200, the workpiece is prevented from being driven by the conveying mechanism 100 to move excessively, such as Figure 1 and Figure 2 As shown, in this embodiment, a rough positioning mechanism 500 is further arranged at the end of the alignment station 200 in the second direction Y, wherein the second direction Y is the conveying direction of the conveying mechanism 100 .

[0083] The coarse positioning mechanism 500 is used to block the movement of the workpiece when it is transported to the alignment station 200, and allows the workpiece to continue to be driven and transported by the conveying mechanism 100 after the workpiece has been aligned, thereby avoiding excessive movement of the workpiece during alignment.

[0084] Specifically, see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the working state structure of an embodiment of the alignment and regularization device of the present application. Figure 6 yes Figure 5 A is a partial enlarged schematic diagram of the middle part.

[0085] like Figure 5 and Figure 6 As shown, the rough positioning mechanism 500 includes a stopper 501 and a lifting unit 502 for controlling the lifting of the stopper 501. The stopper 501 may include a blocking posture and a releasing posture, such as Figure 5 and Figure 6 In the blocking posture shown, the stopper 501 extends out of the surface of the conveying mechanism 100 to limit the workpiece 700 at the alignment station 200 , and in the releasing posture, the stopper 501 retracts below the surface of the conveying mechanism 100 .

[0086] The lifting unit 502 may be mounted on the frame 600 and used to drive the stopper 501 to switch between a blocking posture and a releasing posture.

[0087] Specifically, the lifting unit 502 in this embodiment adopts a structure in which a conventional lifting cylinder and a guide rail are coordinated. The specific structure will not be repeated here. The stop block 501 is installed on the working end of the lifting unit 502. In other embodiments, the lifting unit 502 can also adopt other commonly used lifting structures, such as a screw nut structure, etc., which can achieve the effect of this embodiment.

[0088] Furthermore, an inclined blocking surface 5011 is arranged on the side of the stopper 501 facing the alignment station 200. Based on the inclined blocking surface 5011, the stopper 501 is prevented from scratching the edge of the workpiece 700 and causing the position of the workpiece 700 to change when it shrinks below the surface of the conveying mechanism 100.

[0089] Further, in order to avoid damage to the workpiece 700 due to the blocking effect of the block 501, the block 501 may be an elastic block, such as a PU block.

[0090] Specifically, Figure 2 As shown, in this embodiment, a pair of coarse positioning mechanisms 500 are symmetrically provided on both sides of the end of the alignment station 200 in the second direction Y. In other embodiments, other numbers of coarse positioning mechanisms 500 can be set at the end of the alignment station 200 based on actual working conditions, which can also achieve the effect of this embodiment.

[0091] Based on the alignment and regularization device of the above-mentioned embodiments, when the workpiece to be scribed is transported to the alignment station 200, it can be blocked by the block 501 for rough positioning, and then the corner image of the workpiece is collected by the camera 403 and sent to the controller. The controller obtains the actual position of the workpiece through the corner image of the workpiece, compares the actual position of the workpiece with the preset position, and can output instructions to the first displacement unit 302. The first displacement unit 302 controls the movement of the bearing 3011 based on the instructions, thereby moving the workpiece to the preset position, realizing the alignment and regularization of the workpiece, which can effectively improve the alignment accuracy of the workpiece and help to improve the accuracy of laser marking.
