[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Figure 1 The diagram shown is a structural schematic of an application scenario for a positioning device provided in an embodiment of this application. Figure 2 The image shown is a front-view schematic diagram of a positioning device provided in an embodiment of this application.

[0027] like Figure 1 and Figure 2 As shown, the positioning device 10 is configured to position the boat structure 20. The boat structure 20 includes two end plates 200 and a plurality of connecting rods 201. The two ends of the connecting rods 201 are respectively connected to the two end plates 200.

[0028] Exemplarily, the two end plates 200 are disposed opposite each other along a first direction X1. Exemplarily, the boat structure 20 is any structure capable of supporting sheet material. The sheet material may include silicon wafers, solar cells, wafers, etc. Exemplarily, the connecting rod 201 has a plurality of grooves 204. The grooves 204 on the plurality of connecting rods 201 located on the same plane are used to support the sheet material.

[0029] The positioning device 10 includes: a frame 17, a first support member 11, one or more second positioning members 12, one or more first alignment members 13, one or more first drive components 14, and one or more third positioning members 15 and second drive components 16.

[0030] The frame 17 includes a placement space 173. The placement space 173 is configured to accommodate the boat structure 20. A first support member 11 is movably connected to the frame 17 for supporting the boat structure 20 and is configured to define the position of the boat structure 20 in a first direction X1. The first direction X1 is parallel to the length direction of the connecting rod 201.

[0031] One or more second positioning members 12 are connected to one side of the frame 17. At least a portion of the second positioning member 12 is located on the side of the first support member 11 that supports the boat structure 20. The second positioning member 12 is configured to define the position of the boat structure 20 in a second direction X2. The second direction X2 is perpendicular to the first direction X1.

[0032] For example, refer to Figure 1 and Figure 2Two second positioning elements 12 are shown. The entire structure of both second positioning elements 12 is disposed on one side of the first support member 11 for supporting the boat structure 20. By disposing at least a portion of the second positioning element 12 on the side of the first support member 11 for supporting the boat structure 20, at least a portion of the second positioning element 12 provides a positioning function for the boat structure 20.

[0033] For example, the number of second positioning members 12 may be one. The length of the second positioning member 12 along the first direction X1 may be set to be relatively long in order to better position the boat structure 20.

[0034] One or more first alignment members 13 are movably connected to the side of the frame 17 opposite to the second positioning member 12 and are positioned opposite to the second positioning member 12 along the second direction X2.

[0035] For example, the number of first aligning elements 13 can be one. The length of the first aligning element 13 along the first direction X1 can be set to be relatively long in order to better align the boat structure 20.

[0036] For example, the shape of the first regularizing member 13 may include a plate-like, block-like, column-like, etc. For example, the boat structure 20 has multiple regularized surfaces. The regularizing surfaces of the first regularizing member 13 are configured to position the regularized surfaces. The shape of the regularizing surfaces can be set according to the shape of the regularized surfaces.

[0037] One or more first drive components 14 are connected to the first alignment member 13 and are configured to drive the first alignment member 13 toward or away from the second positioning member 12 along the second direction X2.

[0038] For example, there can be multiple first alignment components 13. A first driving component 14 can be connected to multiple first alignment components 13, so that one first driving component 14 can drive multiple first alignment components 13 to move simultaneously.

[0039] Exemplarily, the first drive assembly 14 may include any structure capable of driving the first prestressing member 13 to move. Exemplarily, the first drive assembly 14 may include one or more combinations of the following drive structures: gear set, sprocket and chain, lead screw and guide rail, cylinder, motor, and crank-slider. This embodiment does not specifically limit the structure of the first drive assembly 14.

[0040] One or more third positioning members 15 are connected to the frame 17. At least a portion of the third positioning member 15 is located on one side of the first support member 11 for supporting the boat structure 20, and is configured to define the position of the boat structure 20 in a third direction X3. The third direction X3 is perpendicular to both the first direction X1 and the second direction X2.

[0041] For example, refer to Figure 1 and Figure 2 The diagram shows two third positioning elements 15, both of which are entirely disposed on one side of the first support member 11 that supports the boat structure 20. By disposing at least a portion of the third positioning element 15 on the side of the first support member 11 that supports the boat structure 20, at least a portion of the third positioning element 15 provides a positioning function for the boat structure 20.

[0042] For example, the number of third positioning members 15 may be one. The length of the third positioning member 15 along the first direction X1 may be set to be relatively long in order to better position the boat structure 20.

[0043] Exemplarily, the shapes of the second positioning member 12 and the third positioning member 15 may include plate-like, block-like, column-like, etc. Exemplarily, the first support member 11, the second positioning member 12, and the third positioning member 15 all have positioning surfaces. The positioning surfaces of the first support member 11, the second positioning member 12, and the third positioning member 15 respectively define the positions of the boat structure 20 in a first direction X1, a second direction X2, and a third direction X3. Exemplarily, the boat structure 20 has multiple positioning surfaces, each corresponding to a positioning surface. The positioning surfaces are configured to position the positioning surfaces. The shape of the positioning surfaces can be set according to the shape of the positioning surfaces.

[0044] The second drive assembly 16 is connected to the first carrier 11 and drives the first carrier 11 along the second direction X2 and the third direction X3, so that the first carrier 11 moves closer to or further away from the second positioning member 12 and the third positioning member 15.

[0045] For example, the second drive component 16 is configured to drive the first carrier 11 along a second direction X2 to bring the first carrier 11 closer to or away from the second positioning member 12, and to drive the first carrier 11 along a third direction X3 to bring the first carrier 11 closer to or away from the third positioning member 15.

[0046] Exemplarily, the second drive assembly 16 can be further configured to drive the first carrier 11 toward or away from the plane containing the positioning surface of the second positioning member 12, and to drive the first carrier 11 toward or away from the plane containing the positioning surface of the third positioning member 15. Exemplarily, the second drive assembly 16 can be further configured to drive the first carrier 11 toward or away from the plane containing the positioning surface of the second positioning member 12 along a second direction X2, and to drive the first carrier 11 toward or away from the plane containing the positioning surface of the third positioning member 15 along a third direction X3. The second drive assembly 16 may include one or more combinations of the following drive structures: gear set, sprocket chain, lead screw guide, cylinder, motor, and crank slider. This embodiment does not specifically limit the structure of the second drive assembly 16.

[0047] For example, one or more of the first support member 11, the second positioning member 12, the first alignment member 13, the first drive assembly 14, the third positioning member 15, and the second drive assembly 16 are disposed on the frame 17.

[0048] Exemplarily, the frame 17 may include two first support frames 170 arranged opposite each other along a second direction X2, and one or more second support frames 171 and one or more third support frames 172 connected to both first support frames 170. One or more second positioning members 12 may be mounted to one of the first support frames 170. A first alignment member 13 may be disposed on the other first support frame 170. One or more third positioning members 15 may be disposed on the second support frame 171. A second drive assembly 16 may be disposed on the third support frame 172. The two first support frames 170, as well as the second support frame 171 and the third support frame 172, may be connected by welding. This arrangement can give the frame 17 higher strength, facilitating better support for components such as the first load-bearing member 11 and the second positioning member 12, as well as the heavy boat structure 20. Exemplarily, the frame 17 may also be integrally formed. Exemplarily, the components of the frame 17 may be detachably connected. Specifically, two first support frames 170, one or more second support frames 171, and one or more third support frames 172 form a placement space 173.

[0049] The positioning device 10 provided in this embodiment defines the position of the boat structure 20 in the first direction X1 through the first bearing member 11. The second driving component 16 drives the first bearing member 11 to move closer to the second positioning member 12 and the third positioning member 15, enabling the first bearing member 11 to support the boat structure 20 as it moves closer to the second and third positioning members 12 and 15. This achieves the first positioning of the boat structure 20, which also facilitates the movement of the heavy boat structure 20. Furthermore, it reduces the distance the boat structure 20 moves when the first straightening member 13 straightens it, thus reducing the burden on the first driving component 14. During the movement of the first carrier 11, the boat structure 20 and the first carrier 11 remain relatively stationary, which can reduce the relative sliding between the boat structure 20 and the first carrier 11, reduce the wear of the boat structure 20 and the first carrier 11, and improve the service life of the boat structure 20 and the positioning device 10. Then, the boat structure 20 is pressed onto the second positioning member 12 by the first alignment member 13, realizing the second positioning of the boat structure 20 in the second direction X2. This can ensure that the boat structure 20 and the second positioning member 12 fit better, the positioning accuracy is higher, and it is more friendly to the subsequent insertion and removal of pieces, reducing the card and fragment rate.

[0050] Exemplarily, the positioning device 10 may further include one or more second alignment members and one or more third drive components. The second alignment member and the third positioning member 15 are disposed opposite each other along a third direction X3. The third drive component is connected to the second alignment member and is configured to drive the second alignment member toward or away from the third positioning member 15. The boat structure 20 is pressed against the third positioning member 15 by the second alignment member, thereby achieving a second positioning of the boat structure 20 in the third direction X3.

[0051] For example, the positioning device 10 may further include one or more third alignment members and one or more fourth drive components. The third alignment member is disposed opposite to the first support member 11 along the first direction X1. The fourth drive component is connected to the third alignment member and is configured to drive the second alignment member to move closer to or away from the first support member 11. The boat structure 20 is pressed against the first support member 11 by the fourth alignment member, thereby achieving a second positioning of the boat structure 20 in the first direction X1.

[0052] In some embodiments, there are multiple second positioning members 12. The multiple second positioning members 12 are spaced apart along a first direction X1. There are multiple first alignment members 13. The multiple first alignment members 13 are respectively arranged opposite to the multiple second positioning members 12 along a second direction X2. There are multiple first driving components 14. The multiple first driving components 14 are respectively connected to the first alignment members 13. There are multiple third positioning members 15. The multiple third positioning members 15 are spaced apart along the first direction X1.

[0053] Specifically, multiple first drive components 14 drive multiple first alignment components 13 to move respectively. This arrangement avoids excessive load on a single first drive component 14, facilitating the positioning and alignment of the heavier boat structure 20. In addition, multiple second positioning components 12 and multiple third positioning components 15 are provided to facilitate the positioning and alignment of the larger boat structure 20, improving the positioning accuracy of the boat structure 20.

[0054] For example, the positioning device 10 includes two first alignment members 13. The two first alignment members 13 are respectively used to alignment the third side surface 205 of the two end plates 200. The third side surface 205 is disposed opposite to the first side surface 202. For example, the first drive assembly 14 and the first alignment member 13 correspond one-to-one.

[0055] In some embodiments, such as Figure 1 and Figure 2As shown, the boat structure 20 includes a first opening 206 for loading and unloading sheet material. The frame 17 includes a second opening 174 and a third opening 175. Both the second opening 174 and the third opening 175 communicate with the placement space 173. The second opening 174 is opposite to the first support member 11 and is used for loading and unloading the boat structure 20. The third opening 175 is in the same direction as the first opening 206 and is used for loading and unloading sheet material. Exemplarily, the boat structure 20 can be placed into the placement space 173 through either the second opening 174 or the third opening 175.

[0056] The second positioning element 12 and the first aligning element 13 are respectively located on both sides of the second opening 174, and the third positioning element 15 is arranged opposite to the third opening 175.

[0057] There are two second positioning members 12, which are spaced apart along the first direction X1 and can abut against the end plates 200 respectively. There are two first alignment members 13, which are respectively positioned opposite to the second positioning members 12 along the second direction X2. There are two third positioning members 15, which are spaced apart along the first direction X1 and can abut against the end plates 200 respectively.

[0058] The positioning device 10 provided in this embodiment has a simple frame structure 17, which facilitates the placement of the boat structure 20. The two second positioning members 12 respectively define the positions of the two end plates 200 in the second direction X2, simplifying the structure of the positioning device 10. In some application scenarios, when the first driving component 14 drives the first alignment member 13 closer to the second positioning member 12 along the second direction X2, the boat structure 20 is pushed by the first alignment member 13 until the two second positioning members 13 respectively abut against the two end plates 200 to position the boat structure 20.

[0059] For example, the positioning device 10 includes two second positioning members 12 and two third positioning members 15. The two second positioning members 12 are used to position the first side surface 202 of the two end plates 200 respectively. The two third positioning members 15 are used to position the second side surface 203 of the two end plates 200 respectively. In the same end plate 200, the first side surface 202 and the second side surface 203 are two adjacent side surfaces. By positioning the two end plates 200 at both ends of the boat structure 20, the positioning of the boat structure 20 is achieved. The positioning of the large-sized boat structure 20 can be achieved with fewer positioning members, and the positioning members can be avoided from being used to position the connecting rod 201, reducing the complexity of the positioning device 10. At the same time, the interference of the positioning members with the sheet material is avoided when inserting or removing the sheet material.

[0060] Figure 3 The diagram shown is a structural schematic of the second drive component and the first carrier provided in an embodiment of this application. Figure 4 The image shown is an embodiment provided by this application. Figure 2 A schematic cross-sectional view of the positioning device along line AA. Figure 5 The image shown is an embodiment provided by this application. Figure 2 A schematic cross-sectional view of the positioning device along line BB.

[0061] In some embodiments, such as Figures 1 to 5 As shown, the second driving component 16 includes: a first driving source 160 and a second driving source 161.

[0062] A first drive source 160 is connected to a first carrier 11 and configured to drive the first carrier 11 to reciprocate along a third direction X3, so that the first carrier 11 moves closer to or away from the third positioning member 15. A second drive source 161 is connected to the first drive source 160 and configured to drive the first carrier 11 to reciprocate along a second direction X2, so that the first carrier 11 moves closer to or away from the second positioning member 12.

[0063] Exemplarily, both the first drive source 160 and the second drive source 161 may include a cylinder drive structure. The piston of the cylinder in the first drive source 160 is connected to the first support member 11. The piston of the cylinder in the second drive source 161 is connected to the first drive source 160. Exemplarily, the first drive source 160 and the second drive source 161 may be directly connected or indirectly connected through other components.

[0064] The positioning device 10 provided in this embodiment drives the first carrier 11 to reciprocate along the third direction X3 via the first driving source 160, and drives the first driving source 160 to reciprocate along the second direction X2 via the second driving source 161, thereby realizing the first carrier 11 moving closer to or away from the third positioning member 15, and the first carrier 11 moving closer to or away from the second positioning member 12. The structure is simple and the complexity of the positioning device 10 is reduced.

[0065] In other embodiments, a first drive source 160 may be connected to a first carrier 11 and configured to drive the first carrier 11 to reciprocate along a second direction X2, so that the first carrier 11 moves closer to or away from the second positioning member 12. A second drive source 161 may be connected to the first drive source 160 and configured to drive the first drive source 160 to reciprocate along a third direction X3, so that the first drive source 160 drives the first carrier 11 to move closer to or away from the third positioning member 15.

[0066] In some embodiments, such as Figures 2 to 4 As shown, the second drive assembly 16 further includes: a second carrier 162, one or more first guide rails 163 and one or more first sliders 164.

[0067] The second support member 162 is disposed on the second drive source 161 and supports the first drive source 160. Under the drive of the second drive source 161, the second support member 162 moves the first drive source 160 closer to or further away from the second positioning member 12. One or more first guide rails 163 are disposed on the second support member 162 and extend along a third direction X3. One or more first sliders 164 are slidably connected to the first guide rails 163 and connected to the first support member 11.

[0068] Due to the large weight of the boat structure 20, the cooperation of the first guide rail 163 and the first slider 164 ensures that the first support member 11 reciprocates along the third direction X3 under the drive of the first drive source 160, thus guaranteeing motion accuracy and improving the stability of the first support member 11 when driven by the first drive source 160. The installation of the second support member 162 facilitates the installation of the first drive source 160, the first guide rail 163, and the first slider 164.

[0069] For example, such as Figure 4 As shown, there can be two first guide rails 163 and four first sliders 164. The two first guide rails 163 are respectively disposed on both sides of the first drive source 160. Each first guide rail 163 is provided with two first sliders 164. This arrangement facilitates stable operation when the first drive source 160 drives the first carrier 11 to move.

[0070] In some embodiments, such as Figures 2 to 4 As shown, the positioning device 10 also includes one or more first stroke limiters 18 and one or more second stroke limiters 19.

[0071] One or more first travel limiters 18 are disposed on the second support member 162. One or more second travel limiters 19 are disposed on the second support member 162 and are spaced apart from the first travel limiters 18 along a third direction X3. The first travel limiters 18 and the second travel limiters 19 are located at both ends of the travel of the first support member 11.

[0072] Specifically, when the first carrier 11 is driven by the first drive source 160 to encounter the first travel limit member 18 or the second travel limit member 19, the first carrier 11 will no longer move due to the drive of the first drive source 160. By setting the first travel limit member 18 and the second travel limit member 19 on both sides of the first carrier 11 along the third direction X3, the driving stroke of the first drive source 160 can be limited, and the movement of the first carrier 11 along the third direction X3 can be automatically stopped. This reduces the need for position sensors or eliminates the need for position sensors, thereby reducing the manufacturing cost of the positioning device 10.

[0073] For example, along the third direction X3, the orthographic projection of the third positioning member 15 on the first carrier member 11 is located between the orthographic projection of the first travel limit member 18 on the first carrier member 11 and the orthographic projection of the second travel limit member 19 on the first carrier member 11.

[0074] For example, the travel distance of the first carrier 11 can be set according to factors such as the size of the first carrier 11, the position of the third positioning member 15, and the size of the boat structure 20. The travel distance of the first carrier 11 can be set according to actual needs, and this embodiment does not impose specific limitations. For example, in some application scenarios, the first carrier 11 carries the boat structure 20 close to the third positioning member 15. After the boat structure 20 contacts the third positioning member 15, the first carrier 11 touches the second travel limit member 19, and the first carrier 11 stops moving in the third direction X3.

[0075] In some embodiments, such as Figure 3 and Figure 5 As shown, the second drive assembly 16 further includes: a base plate 167, one or more second guide rails 165, and one or more second sliders 166. One or more second guide rails 165 are connected to the base plate 167 and extend along a second direction X2. One or more second sliders 166 are slidably connected to the second guide rails 165.

[0076] Because the boat structure 20 is heavy, and the second drive source 161 also has to support the first drive source 160, the first guide rail 163, and the first slider 164, the cooperation of the second guide rail 165 and the second slider 166 ensures that the first drive source 160 moves back and forth along the third direction X3 under the drive of the second drive source 161, thus ensuring motion accuracy and improving the stability when driving the first drive source 160 to move. This ensures that the boat structure 20 can move smoothly when the first support member 11 supports the boat structure 20.

[0077] For example, such as Figure 5 As shown, there can be two second guide rails 165. There can be four second sliders 166. The two second guide rails 165 are respectively disposed on both sides of the first drive source 160. Each second guide rail 165 is provided with two second sliders 166. Exemplarily, the base plate 167 is connected to the frame 17.

[0078] In some embodiments, such as Figure 3 and Figure 5 As shown, the positioning device 10 also includes one or more third stroke limiters 30 and one or more fourth stroke limiters 31.

[0079] One or more third stroke limiters 30 are connected to one end of the base plate 167. A fourth stroke limiter 31 is connected to the other end of the base plate 167 and is spaced apart from the third stroke limiters 30 along the second direction X2. The third stroke limiters 30 and the fourth stroke limiters 31 are located at both ends of the travel stroke of the second support member 162.

[0080] Specifically, when the second carrier 162 is driven by the second drive source 161 to encounter the third travel limit member 30 or the fourth travel limit member 31, the second carrier 162 will no longer move due to the drive of the second drive source 161. By providing the third travel limit member 30 and the fourth travel limit member 31 on both sides of the second carrier 162 along the second direction X2, the sliding stroke of the second slider 166 can be limited, enabling the movement of the second carrier 162 along the second direction X2 to stop automatically. This reduces the need for position sensors or eliminates the need for position sensors, thereby lowering the manufacturing cost of the positioning device 10.

[0081] For example, along the second direction X2, the orthographic projection of the second positioning member 12 on the second carrier member 162 is located between the orthographic projection of the third travel limit member 30 on the second carrier member 162 and the orthographic projection of the fourth travel limit member 31 on the second carrier member 162.

[0082] For example, the travel distance of the second support member 162 can be set according to factors such as the size of the second support member 162, the position of the second positioning member 12, and the size of the boat structure 20. The travel distance of the second support member 162 can be set according to actual needs, and this embodiment does not impose specific limitations.

[0083] In some embodiments, such as Figure 3 As shown, the positioning device 10 also includes one or more buffer members 32. One or more buffer members 32 are disposed on one side of the first support member 11 for supporting the boat structure 20.

[0084] For example, the buffer 32 may include a hydraulic buffer or a spring, elastic cushioning pad, or other elastic structure. Since the boat structure 20 is relatively heavy, the buffer 32 acts as a buffer when the boat structure 20 is placed on the first support member 11, preventing a hard landing of the boat structure 20 and reducing shaking and impacts during placement, thereby improving the lifespan of the boat structure 20.

[0085] In some embodiments, such as Figure 3 As shown, the first support member 11 includes a support member body 110 and one or more protrusions 111. One or more protrusions 111 are disposed on the side of the support member body 110 facing the boat structure 20. The protrusions 111 are configured to support the boat structure 20 and define the position of the boat structure 20 in a first direction X1. A buffer member 32 is disposed on the support member body 110.

[0086] For example, the carrier body 110 and the protrusion 111 can be fixedly connected or detachably connected. For example, the first carrier 11 can be integrally formed.

[0087] By providing a protrusion 111 on the side of the support body 110 facing the boat structure 20, a recessed area is formed on the side of the support body 110 facing the boat structure 20. A buffer 32 is provided on the support body 110 and located within the recessed area on the side of the support body 110 facing the boat structure 20. This arrangement prevents the buffer 32 from affecting the limitation of the protrusion 111 on the position of the boat structure 20 in the first direction X1.

[0088] For example, a plurality of protrusions 111 are provided on the edge region of the support body 110 on the side facing the boat structure 20. The buffer 32 is provided in the region surrounded by the plurality of protrusions 111.

[0089] In some embodiments, the material of the second positioning element may be a wear-resistant material. Wear-resistant materials are one of the following: ceramics, polyetheretherketone (PEEK), nylon, and polyoxymethylene (POM).

[0090] For example, the material of the third positioning member can also be a wear-resistant material. For example, a first positioning member is provided on the side of the first support member 11 facing the boat structure 20. The first positioning member is configured to support the boat structure 20 and define the position of the boat structure 20 in the first direction X1. The material of the first positioning member can also be a wear-resistant material.

[0091] In some embodiments, such as Figure 2 As shown, the positioning device 10 also includes a rotary drive device 33. The rotary drive device 33 is rotatably connected to the frame 17 and is configured to drive the frame 17 to rotate so that the third positioning member 15 defines the position of the boat structure 20 in the third direction X3.

[0092] For example, the rotary drive device 33 may include one or a combination of multiple of the following: a motor drive mechanism, a lever mechanism, a hydraulic or pneumatic mechanism, and a gear transmission mechanism.

[0093] For example, refer to Figure 1The first support member 11 is initially positioned horizontally, and the boat structure 20 is placed vertically on the positioning device 10. The second drive assembly 16 drives the first support member 11 to move, achieving the first positioning of the boat structure 20. Then, the first alignment member 13 presses the boat structure 20 onto the second positioning member 12, achieving the second positioning of the boat structure 20 in the second direction X2. The first alignment member 13 releases the boat structure 20, and then the rotation drive device 33 rotates the positioning device 10 by 90°. The third positioning member 15 then supports the boat structure 20, achieving the second positioning of the boat structure 20 in the third direction X3. For example, after the boat structure 20 is positioned in the third direction X3 in the above manner, the boat structure 20 is in a horizontal state, and sheet material can be placed into the boat structure 20 through the third opening 175.

[0094] The positioning device 10 provided in this embodiment rotates the third positioning member 15 to limit the position of the boat structure 20 in the third direction X3 by rotating the rotation drive device 33. This makes the positioning device 10 suitable for more application scenarios, such as application scenarios that require changing the placement state of the boat structure 20, and facilitates the placement of sheet materials into the positioned boat structure 20.
