[0007] At least two conveying lines are configured to convey the sheet along a first direction, and at least two conveying lines are arranged side by side along a second direction, and the first direction is perpendicular to the second direction;

[0008] A tidying station is arranged on the conveying path of each conveying line, and a tidying assembly is arranged at the tidying station, the tidying assembly comprises a first tidying plate, a second tidying plate and a driving assembly, the first tidying plate and the second tidying plate are respectively arranged on opposite sides of the conveying line in the second direction, and the driving assembly is configured to drive the first tidying plate and the second tidying plate to move closer to or away from each other;

[0009] The conveyor line conveys the sheet to the tidying station, and the sheet on the tidying station is tidyed by the first tidying plate and the second tidying plate.

[0010] The sheet tidying mechanism proposed in the present application is provided with a tidying component on each conveying line. The tidying component adopts a driving component to drive the first tidying plate and the second tidying plate to move closer to or away from each other. This not only simplifies the overall structure of the tidying mechanism and reduces the cost, but also makes the overall structure of the tidying mechanism compact and occupies little space.

[0011] In some embodiments, the regular components on two adjacent conveyor lines are staggered in the first direction.

[0012] By staggering the regular components on two adjacent conveyor lines in the first direction, the space occupied by the two conveyor lines in the width direction can be further reduced, making the layout of the two conveyor lines in the width direction more compact.

[0013] In some embodiments, the feed end of the first and / or second regularized plate is tilted toward the outside of the regularization station, so that the feed end opening of the regularization station is trumpet-shaped to facilitate the entry of the sheet into the regularization station.

[0014] By setting the feed end of the first regularizing plate and / or the second regularizing plate to be inclined toward the outside of the regularizing station, the feed end opening of the regularizing station is made trumpet-shaped, which facilitates the sheet to enter the regularizing station and also enables the sheet to be preliminarily regularized before entering the regularizing station.

[0015] In some embodiments, the conveyor line includes a conveyor frame and a conveyor belt, the conveyor belt is rotatably mounted on the conveyor frame, the driving assembly includes a fixed seat, a driving member and a transmission assembly, the fixed seat is arranged below the conveyor belt, the first regularized plate and the second regularized plate are movably mounted on the fixed seat and are arranged higher than the conveyor belt, and the driving member drives the first regularized plate and the second regularized plate to synchronously approach or move away from the conveyor belt through the transmission assembly.

[0018] The driving member drives the turntable to rotate, and then drives the first regularized plate and the second regularized plate to synchronously approach or move away from the conveyor belt through the first cam follower and the second cam follower.

[0019] Through the cooperation of the driving member, the first cam follower, the second cam follower and the turntable, the rotational motion of the turntable is converted into the linear motion of the first regularized plate and the second regularized plate synchronously approaching or moving away from the conveyor belt, providing a transmission component with high transmission accuracy, stability and reliability, and long service life.

[0020] In some embodiments, both the first track groove and the second track groove are arc grooves, and the corresponding cam follower maintains contact with the inner and outer walls of the arc groove when moving in the arc groove, and the distance between the center of the cam follower and the center of the turntable at each point on the moving path gradually increases clockwise or counterclockwise.

[0021] By setting the first track groove and the second track groove as arc grooves, the distance between the center of the cam follower and the center of the turntable at each point on the moving path in a clockwise or counterclockwise direction gradually increases, thereby realizing the conversion of the rotational motion of the turntable into the movement of the two cam followers approaching or moving away from each other, thereby driving the first regularized plate and the second regularized plate to approach or move away from the conveyor belt synchronously; at the same time, the cam follower maintains contact with the inner and outer walls of the arc groove when moving, which can further improve the transmission stability and transmission accuracy.

[0022] In some embodiments, a guide assembly is disposed between the first and second structured plates and the fixed seat, and the guide assembly is configured to guide the first and second structured plates when they approach or move away from the conveyor belt.

[0023] By providing the guide assembly, the stability and reliability of the movement of the first regularized plate and the second regularized plate are improved.

[0024] In some embodiments, the guide assembly includes a linear guide rail and a slider, the linear guide rail is fixed on a fixed seat and extends along the second direction, and the first regularized plate or the second regularized plate is installed on the linear guide rail through the slider.

[0025] Through the cooperation of the linear guide rail and the slider, the movement of the first regular plate and the second regular plate is supported and guided, providing a guide component with simple structure, low cost and high reliability.

[0026] In some embodiments, flexible pads are installed on the inner side surfaces of the first and second structured plates close to the conveyor line.

[0027] By installing flexible pads on the inner sides of the first and second regular plates close to the conveyor line, direct hard contact between the first and second regular plates and the sheet body is avoided, thereby protecting the sheet body.

[0028] In some embodiments, when the conveyor line conveys the sheet, the driving assembly is configured to drive the first tidying plate and the second tidying plate away from each other so that the sheet enters the tidying station, and the driving assembly is further configured to drive the first tidying plate and the second tidying plate closer to each other so as to perform tidying on the sheet at the tidying station;

[0029] Alternatively, the driving component drives the first regularizing plate and the second regularizing plate to move closer to or away from each other, so that the first regularizing plate and the second regularizing plate move to a preset distance, and the conveyor line conveys the sheet to the regularizing station, and the first regularizing plate and the second regularizing plate are used to regularize the sheet on the regularizing station.

[0043] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] In the process of processing wafers (such as silicon wafers, battery cells, etc.), in order to improve production efficiency, two conveyor lines arranged side by side are usually set up to convey the wafers simultaneously. Each conveyor line is equipped with a regularizing mechanism, which regularizes the wafers conveyed on the conveyor line.

[0045] The existing straightening mechanism usually adopts straightening rollers or straightening belts on both sides of each conveyor line, which has a high processing cost; and a large space needs to be reserved between the two conveyor lines to install the straightening rollers or straightening belts, which occupies a large space.

[0046] Therefore, the present application provides a sheet body regularization mechanism, please refer to Figures 1 to 3 As shown, the sheet tidying mechanism provided in the embodiment of the present application includes at least two conveying lines 10, wherein: at least two conveying lines 10 are configured to be arranged along a first direction ( Figure 1 The sheet 30 is transported in the X direction) by at least two conveying lines 10 along the second direction ( Figure 1 The first and second directions are arranged side by side, and the first direction is perpendicular to the second direction; a tidying station 11 is arranged on the conveying path of each conveyor line 10, and a tidying assembly 20 is arranged at the tidying station 11, and the tidying assembly 20 includes a first tidying plate 21, a second tidying plate 22 and a driving assembly 23, and the first tidying plate 21 and the second tidying plate 22 are respectively arranged on the opposite sides of the conveyor line 10 in the second direction, and the driving assembly 23 is configured to drive the first tidying plate 21 and the second tidying plate 22 to approach or move away from each other; the conveyor line 10 conveys the sheet 30 to the tidying station 11, and the sheet 30 on the tidying station 11 is tidyed by the first tidying plate 21 and the second tidying plate 22.

[0047] It can be seen that a tidying component 20 is provided on each conveying line 10 of the sheet tidying mechanism proposed in the present application. The tidying component 20 adopts a driving component 23 to drive the first tidying plate 21 and the second tidying plate 22 to move closer to or away from each other. This not only simplifies the overall structure of the tidying mechanism and reduces the cost; the overall structure of the tidying mechanism is compact and occupies little space.

[0048] As an embodiment, the regularization components 20 on two adjacent conveyor lines 10 are staggered in the first direction.

[0049] It can be seen that by staggering the regular components 20 on two adjacent conveyor lines 10 in the first direction, the space occupied by the two conveyor lines 10 in the width direction (i.e., the second direction) can be further reduced, making the layout of the two conveyor lines 20 in the width direction more compact.

[0050] As an embodiment, the feed end of the first tidying plate 21 and / or the second tidying plate 22 is inclined toward the outside of the tidying station 11 , so that the feed end opening of the tidying station 11 is trumpet-shaped to facilitate the sheet 30 to enter the tidying station 11 .

[0051] Specifically, only the feeding end of the first tidying plate 21 is inclined toward the outside of the tidying station 11 , so that the feeding end opening of the tidying station 11 is trumpet-shaped, so that the sheet 30 can enter the tidying station 11 easily.

[0052] Alternatively, only the feeding end of the second tidying plate 22 is inclined toward the outside of the tidying station 11 , so that the feeding end opening of the tidying station 11 is trumpet-shaped, so as to facilitate the sheet 30 to enter the tidying station 11 .

[0053] Alternatively, the feeding ends of the first and second structured plates 21 and 22 are respectively inclined toward the two sides of the structured station 11 , so that the feeding end opening of the structured station 11 is trumpet-shaped to facilitate the sheet 30 to enter the structured station 11 .

[0054] It can be seen that by setting the feed end of the first regularizing plate 21 and / or the second regularizing plate 22 to be inclined toward the outside of the regularizing station 11, the feed end opening of the regularizing station 11 is made trumpet-shaped, which facilitates the sheet 30 to enter the regularizing station 11, and also enables the sheet 30 to be preliminarily regularized before entering the regularizing station 11.

[0055] As an embodiment, the conveyor line 10 includes a conveyor frame 100 and a conveyor belt 101, the conveyor belt 101 is rotatably mounted on the conveyor frame 100, the driving assembly 23 includes a fixed seat 230, a driving member 231 and a transmission assembly, the fixed seat 230 is arranged below the conveyor belt 101, the first regularized plate 21 and the second regularized plate 22 are movably mounted on the fixed seat 230 and are arranged higher than the conveyor belt 101, and the driving member 231 drives the first regularized plate 21 and the second regularized plate 22 to synchronously approach or move away from the conveyor belt through the transmission assembly.

[0056] Specifically, the conveyor belt 101 includes two narrow conveyor belts arranged in parallel along the second direction, and the two narrow conveyor belts are rotatably mounted on the conveyor frame 100 .

[0057] Specifically, the driving member 231 is a motor.

[0058] It can be seen that by setting the fixed seat 230 below the conveyor belt 101, the space at the conveyor line 10 can be reasonably utilized, providing a driving component 23 with a compact structure, small space occupation and reasonable layout; the driving member 231 drives the first regularized plate 21 and the second regularized plate 22 to synchronously approach or move away from the conveyor belt 101 through the transmission component, and realizes that the first regularized plate 21 and the second regularized plate 22 are driven synchronously to approach or move away from the conveyor belt 101 at the same time by one driving member 231, providing a driving component 23 with a simple structure and low cost.

[0059] See also Figure 1 , Figures 3 to 5 As shown, as an embodiment, the transmission assembly includes a first cam follower 232, a second cam follower 233 and a turntable 234, the fixed end of the driving member 231 is mounted on the fixed seat 230, the driving end of the driving member 231 is connected to the turntable 234, the driving member 231 is configured to drive the turntable 234 to rotate, and the turntable 234 is centrally symmetrically provided with a first track groove 2340 and a second track groove 2341, the first end of the first cam follower 232 is mounted on the first regularized plate 21, the second end of the first cam follower 232 is located in the first track groove 2340, the first end of the second cam follower 233 is mounted on the second regularized plate 22, and the second end of the second cam follower 233 is located in the second track groove 2341; the driving member 231 drives the turntable 234 to rotate, and then drives the first regularized plate 21 and the second regularized plate 22 to synchronously approach or move away from the conveyor belt 101 through the first cam follower 232 and the second cam follower 233.

[0060] Specifically, the bottom of the first regularized plate 21 is bent and extended toward the side close to the conveyor line 10 to form a first connecting portion 210, a first connecting piece 211 is installed on the first connecting portion 210, and a first end of the first cam follower 232 is installed on the first connecting piece 211; the bottom of the second regularized plate 22 is bent and extended toward the side close to the conveyor line 10 to form a second connecting portion 220, a second connecting piece 221 is installed on the second connecting portion 220, and a first end of the second cam follower 233 is installed on the second connecting piece 221.

[0061] It can be seen that through the cooperation of the driving member 231, the first cam follower 232, the second cam follower 233 and the turntable 234, the rotational motion of the turntable 234 is converted into a linear motion of the first regularized plate 21 and the second regularized plate 22 synchronously approaching or moving away from the conveyor belt 101, providing a transmission component with high transmission accuracy, stable and reliable transmission and long service life.

[0062] See also Figure 1 , Figure 4 and Figure 6As shown, as an embodiment, the first track groove 2340 and the second track groove 2341 are both arc grooves, and the corresponding cam follower maintains contact with the inner and outer walls of the arc groove when moving in the arc groove, and the distance between the center of the cam follower and the center of the turntable 234 gradually increases clockwise or counterclockwise at each point on the moving path.

[0063] It can be seen that by setting the first track groove 2340 and the second track groove 2341 as arc grooves, the distance between the center of the cam follower and the center of the turntable at each point on the moving path in a clockwise or counterclockwise direction gradually increases, thereby realizing the conversion of the rotational motion of the turntable 234 into the two cam followers (i.e., the first cam follower 232 and the second cam follower 233) moving closer to or farther away from each other, thereby driving the first regular plate 21 and the second regular plate 22 to synchronously approach or move away from the conveyor belt 101; at the same time, the cam follower maintains contact with the inner and outer walls of the arc groove when moving, which can further improve the stability and accuracy of the transmission.

[0064] See also Figure 3 As shown, as an embodiment, a guide assembly 40 is provided between the first regularized plate 21 and the second regularized plate 22 and the fixed seat 230 , and the guide assembly 40 is configured to guide the first regularized plate 21 and the second regularized plate 22 when they approach or move away from the conveyor belt 101 .

[0065] It can be seen that by providing the guide assembly 40, the stability and reliability of the movement of the first regularized plate 21 and the second regularized plate 22 are improved.

[0066] As an embodiment, the guide assembly 40 includes a linear guide rail 41 and a slider 42 . The linear guide rail 41 is fixed on the fixing seat 230 and extends along the second direction. The first regularized plate 21 or the second regularized plate 22 is installed on the linear guide rail 41 through the slider 42 .

[0067] It can be seen that through the cooperation of the linear guide rail 41 and the slider 42, the support and guidance of the movement of the first regular plate 21 and the second regular plate 22 are achieved, providing a guide component 40 with simple structure, low cost and high reliability.

[0068] As an implementation manner, flexible pads 50 are installed on the inner side surfaces of the first regularized plate 21 and the second regularized plate 22 close to the conveyor line 10 .

[0069] Specifically, the flexible pad 50 is arranged to cover the inner side surfaces of the first regularized plate 21 and the second regularized plate 22 , and the inner side surfaces are surfaces that are in contact with the sheet body during regularization.

[0070] It can be seen that by installing the flexible pad 50 on the inner side of the first regular plate 21 and the second regular plate 22 close to the conveyor line 10, direct hard contact between the first regular plate 21 and the second regular plate 22 and the sheet 30 is avoided, thereby protecting the sheet 30.

[0071] See also Figures 1 to 3 As shown, as an embodiment, when the conveyor line 10 conveys the sheet 30, the driving assembly 23 is configured to drive the first tidying plate 21 and the second tidying plate 22 away from each other, so that the sheet 30 enters the tidying station 11, and the driving assembly 23 is also configured to drive the first tidying plate 21 and the second tidying plate 22 to approach each other, so as to perform tidying on the sheet 30 at the tidying station 11;

[0072] Alternatively, the driving component 23 drives the first tidying plate 21 and the second tidying plate 22 to move closer to or farther from each other, so that the first tidying plate 21 and the second tidying plate 22 move to a preset distance, and the conveyor line 10 conveys the sheet 30 to the tidying station 11, and the sheet 30 on the tidying station 11 is tidyed by the first tidying plate 21 and the second tidying plate 22

[0073] It can be seen that two different application scenarios of the sheet regularization mechanism are provided. In the first application scenario, during the regularization process, the driving component 23 is always in a working state, driving the first regularization plate 21 and the second regularization plate 22 to alternately approach or move away; in the second application scenario, the driving component 23 only works before regularization, adjusting the first regularization plate 21 and the second regularization plate 22 to a suitable spacing, and during the regularization process, the driving component 23 does not work, thereby improving the compatibility of the sheet regularization mechanism.

[0074] The present application provides a sheet regularization mechanism having the following advantages:

[0075] 1) Simple structure, low cost, compact structure and small space occupation;

[0076] 2) The feeding end of the regularization station is open in a trumpet shape, which is convenient for the sheet to enter the regularization station;

[0077] 3) The drive components make reasonable use of the space at the conveyor line, occupying a small space and with a reasonable layout;

[0078] 4) The transmission method of turntable and two cam followers is adopted, which has high transmission accuracy, stability and reliability, and long service life.

[0079] The above embodiments are only to illustrate the basic principles and characteristics of the present application. The present application is not limited by the above examples.
