Description

Technical Field

[0001] This application relates to the field of conveying technology, and in particular to a flipping disc and sheet flipping conveying device. Background Technology

[0002] In the production of solar cells, basic manufacturing processes include cleaning and texturing, film deposition, and screen printing. The screen printing process consists of four stages: first, printing the back-side sub-busbars; second, printing the back-side main busbars; third, printing the front-side sub-busbars; and fourth, printing the front-side main busbars. After the second printing stage, the cells need to be flipped using a flipper so that the front side faces up for the subsequent three printing stages. However, during the flipping process, debris and other contaminants can easily remain on the flipper blades, causing dirt and scratches on the cells. Therefore, the blades need to be removed from the flipper for cleaning. Utility Model Content

The engaging and fixing of the supporting blade and the fixing mechanism by the guide groove and guide rail is then released by sliding. This application enables rapid disassembly of the supporting blade in the tilting tray, improving replacement efficiency and meeting the requirements for disassembly in confined spaces.

[0036] In traditional technology, a rotating disc has blades arranged radially from a center. The solar cells are sandwiched between two blades, and the cells rotate with the disc, causing them to flip. The blades are bolted to a support frame. However, because the supporting blades are prone to getting dirty and retaining debris during use, this can scratch and soil the solar cells during flipping. Furthermore, bolting makes it inconvenient to disassemble the supporting blades, and wrenches are difficult to use in confined spaces. This results in low disassembly efficiency of the rotating disc, long downtime for the rotating machine, and a significant impact on solar cell production efficiency.

[0037] Based on this, the first aspect of this application provides a flip disk, such as Figure 1 and Figure 2 As shown, the flip plate 100 includes a fixing mechanism 110, a supporting blade 120, and a connecting mechanism 130.

[0038] The fixing mechanism 110 has multiple first positioning holes 111 around its center. Multiple supporting blades 120 are arranged at intervals around the center of the fixing mechanism 110. Each supporting blade 120 has multiple second positioning holes 121. At least two of the second positioning holes 121 in the supporting blade 120 correspond to at least two of the first positioning holes 111. Figure 2 As shown, the connecting mechanism 130 includes a guide rail 131 and a guide groove 132 respectively disposed on the fixing mechanism 110 and the supporting blade 120. The guide rail 131 and the guide groove 132 are engaged and connected. Figure 3 As shown, the connecting mechanism 130 also includes a positioning pin 133 and an elastic element 134. The positioning pin 133 is inserted into the first positioning hole 111 and the second positioning hole 121 corresponding to the position. One end of the elastic element 134 is connected to the positioning pin 133, and the other end is connected to the fixing mechanism 110 or the supporting blade 120, so as to adjust the depth of the positioning pin 133 in the first positioning hole 111 and the second positioning hole 121 by compression and rebound.

[0039] This application, based on the engagement connection between the supporting blade 120 and the fixing mechanism 110 achieved by the guide rail 131 and guide groove 132, further utilizes the positioning pin 133 in conjunction with the elastic element 134 to achieve the positioning of the supporting blade 120 and the fixing mechanism 110, ensuring a stable connection between the supporting blade 120 and the fixing mechanism 110. Specifically, in the fixed state, the positioning pin 133, under the elastic force applied by the elastic element 134, simultaneously inserts into the first positioning hole 111 in the supporting blade 120 and the second positioning hole 121 on the fixing mechanism 110, thus achieving the connection between the supporting blade 120 and the fixing mechanism 110. In the disassembled state, manually lifting the positioning pin 133, resisting the elastic force of the elastic element 134, causes the positioning pin 133 to disengage from either the first positioning hole 111 or the second positioning hole 121, thereby canceling the positioning of the supporting blade 120 and the fixing mechanism 110, and the engagement and fixing of the supporting blade 120 and the fixing mechanism 110 by sliding the guide groove 132 and guide rail 131 is released. This application enables the rapid disassembly of the support blade 120 in the flip plate 100, improving replacement efficiency and meeting the requirements for disassembly in confined spaces.

[0040] It is understood that the elastic element 134 is located in the fixing mechanism 110 or the supporting blade 120. It cannot be located with one end in the fixing mechanism 110 and the other end in the supporting blade 120. In other words, after the positioning pin 133 is removed from the positioning connection between the fixing mechanism 110 and the supporting blade 120, the elastic element 134 should not be located between the fixing mechanism 110 and the supporting blade 120, thus preventing the fixing mechanism 110 and the supporting blade 120 from separating.

[0041] In some embodiments, such as Figure 3 As shown, the connecting mechanism 130 also includes a blocking member 135, and a protrusion 1331 is provided on the positioning pin 133. The blocking member 135 is disposed in the first positioning hole 111 or the second positioning hole 121. The two ends of the elastic member 134 are respectively connected to the protrusion 1331 and the blocking member 135, so as to adjust the depth of the positioning pin 133 in the first positioning hole 111 and the second positioning hole 121 by compression and rebound. This application utilizes the blocking of the protrusion 1331 and the blocking member 135 to adjust the positioning pin 133 by the rebound and compression of the elastic member 134.

[0042] In some embodiments, such as Figure 3 As shown, the protrusion 1331 is disposed at the insertion portion of the positioning pin 133. It can be understood that the insertion portion refers to the part where the positioning pin 133 is inserted into the first positioning hole 111 and the second positioning hole 121 in the fixed state. This application provides the protrusion 1331 at the insertion portion of the positioning pin 133 so that the elastic element 134 can be located within the positioning hole, preventing the elastic element 134 from being exposed externally and affecting equipment operation.

[0043] In some embodiments, in the positioning state, a protrusion 1331 is disposed in the area where the positioning pin 133 is inserted into the first positioning hole 111, the diameter of the protrusion 1331 is the same as the diameter of the first positioning hole 111, and the diameter of the positioning pin 133 is the same as the diameter of the second positioning hole 121.

[0044] In some embodiments, in the positioning state, a protrusion 1331 is disposed in the area where the positioning pin 133 is inserted into the second positioning hole 121, the diameter of the protrusion 1331 is the same as the diameter of the second positioning hole 121, and the diameter of the positioning pin 133 is the same as the diameter of the first positioning hole 111.

[0045] It is understandable that when the diameters of the first positioning hole 111 and the second positioning hole 121 are not the same, the diameter of the protrusion 1331 is made to be the same as the diameter of one of the positioning holes, and the diameter of the positioning pin 133 is the same as the diameter of the other positioning hole. That is, when the positioning pin 133 is inserted into the positioning hole and held in a positioning state, both the protrusion 1331 and the portion of the positioning pin 133 can fill the corresponding positioning hole, thereby avoiding the problem of significant gaps between the positioning pin 133 and the positioning hole causing wobbling. It should be noted that, to ensure that the positioning pin 133 can be inserted into the first positioning hole 111 and the second positioning hole 121, those skilled in the art can set the position of the protrusion 1331, the diameter of the protrusion 1331, and the diameter of the positioning pin 133 according to the usage requirements.

[0046] In some embodiments, the diameter of the protrusion 1331, the diameter of the first positioning hole 111, and the diameter of the second positioning hole 121 are the same.

[0047] In some embodiments, the length of the protrusion 1331 is greater than the depth of the first positioning hole 111 or the depth of the second positioning hole 121.

[0048] The dimensions of the protrusion 1331, the first positioning hole 111, and the second positioning hole 121 are configured as described above to ensure that after the positioning pin 133 is inserted, the protrusion 1331 can cover the connection between the first positioning hole 111 and the second positioning hole 121, thereby effectively ensuring that the protrusion 1331 fills the first positioning hole 111 and the second positioning hole 121 and improving positioning stability.

[0049] In some embodiments, such as Figure 3As shown, the blocking member 135 is integrally formed with the fixing mechanism 110, or the blocking member 135 is detachably mounted on the fixing mechanism 110. Alternatively, the blocking member 135 is integrally formed with the supporting blade 120, or the blocking member 135 is detachably mounted on the supporting blade 120. Optionally, the blocking member 135 can be an annular baffle directly attached to the fixing mechanism 110 or the supporting blade 120. Alternatively, the blocking member 135 can be an annular baffle with external threads, which can be detachably mounted on the fixing mechanism 110 or the supporting blade 120 by screwing.

[0050] In some embodiments, the protrusion 1331 is integrally formed with the positioning pin 133, or the protrusion 1331 is detachably disposed on the positioning pin 133. For example, the protrusion 1331 has a through hole inside, and the inner wall of the through hole is provided with threads, so it can be detachably disposed on the positioning pin 133 by means of thread engagement.

[0051] In some embodiments, the elastic element 134 only needs to satisfy the requirements of compression and rebound under elastic force. For example, the elastic element 134 can be a spring sleeved on the locating pin 133.

[0052] like Figure 2 As shown, the guide rail 131 is disposed on the supporting blade 120, and the guide groove 132 is formed on the fixing mechanism 110. Alternatively, the guide groove 132 is formed on the supporting blade 120, and the guide rail 131 is disposed on the fixing mechanism 110.

[0053] In some embodiments, such as Figure 2 As shown, an anti-detachment component 1321 is provided on the guide groove 132 for engaging the guide rail 131. Optionally, the anti-detachment component 1321 can be at least one baffle provided at the opening of the guide groove 132. For example, an integral baffle can be provided at the opening of the guide groove 132 along the length of the guide groove 132, or multiple baffles can be provided at intervals along the length of the guide groove 132. The baffle can be provided only on one side of the opening of the guide groove 132, or it can be provided on both sides of the opening of the guide groove 132. It is understood that even if the anti-detachment component 1321 is provided on the guide groove 132, the guide rail 131 can still slide in the guide groove 132, and the baffle will not completely seal the opening of the guide groove 132. That is, this application uses the baffle to prevent the guide rail 131 from falling out of the guide groove 132, thereby achieving the engaging connection between the supporting blade 120 and the fixing mechanism 110.

[0054] In some embodiments, the bottom width of the guide groove 132 is greater than the opening width of the guide groove 132, and the cross-sectional shape of the guide rail 131 is the same as the cross-sectional shape of the guide groove 132. In this application, the guide groove 132 and the guide rail 131 are configured to have the same cross-sectional shape, and the bottom width of the guide groove 132 is greater than the opening width. This size setting prevents the guide rail 131 from falling off in the depth direction of the guide groove 132, and enables the guide groove 132 and the guide rail 131 to slide in the length direction, thereby allowing the fixing mechanism 110 and the supporting blade 120 to engage.

[0055] In some embodiments, both the guide rail 131 and the guide groove 132 extend in a direction toward the center of the fixing mechanism 110. The arrangement direction of the guide rail 131 and the guide groove 132 is as described above. During rotation, the guide rail 131 and the guide groove 132 have a large effective area, thereby ensuring the connection stability of the supporting blade 120 in the rotational direction.

[0056] In some embodiments, such as Figure 2 As shown, a pin head 1332 is provided on the side of the positioning pin 133 away from the insertion portion of the positioning pin 133. The diameter of the pin head 1332 is larger than the diameter of the first positioning hole 111 and the diameter of the second positioning hole 121. The provision of the pin head 1332 on the positioning pin 133 in this application facilitates the removal of the positioning pin 133 from the positioning hole.

[0057] Optionally, a detachable knob (not shown in the figure) is provided at the end of the positioning pin 133 away from the pin head 1332. The diameter of the knob is larger than the diameter of the first positioning hole 111 and the second positioning hole 121, and the side of the positioning pin 133 away from the pin head 1332 has a thread that mates with the knob. After the positioning pin 133 is inserted into the first positioning hole 111 and the second positioning hole 121 and protrudes from the holes, the protruding part of the positioning pin 133 can be tightened using the knob. On the one hand, the knob and the pin head 1332 cooperate to strengthen the clamping and fixing of the supporting blade 120 and the fixing mechanism 110; on the other hand, the knob can further strengthen the position of the positioning pin 133 in the hole, avoiding the problem of the supporting blade 120 falling off due to the failure of the elastic element 134. It is understood that since the supporting blade 120 and the fixing mechanism 110 are connected by the connection mechanism 130 of this application, the knob can be disassembled manually, compared to the bolt connection.

[0058] Exemplarily, a method for disassembling and assembling the support blade 120 using the aforementioned flip plate 100 is provided, comprising the following steps:

[0059] S1. Installation Method

[0060] The supporting blade 120 and the fixing mechanism 110 are engaged along the guide rail 131 and the guide groove 132. The elastic member 134 is placed on the protrusion 1331 of the positioning pin 133, and the side of the positioning pin 133 with the protrusion 1331 is inserted into the first positioning hole 111 and the second positioning hole 121. Then, the blocking member 135 is installed at the first positioning hole 111, so that the elastic member 134 is compressed between the blocking member 135 and the protrusion 1331. Under the elastic force of the elastic member 134, the positioning pin 133 is kept inserted into the first positioning hole 111 and the second positioning hole 121. Understandably, the positioning pin 133, the blocking member 135, and the elastic member 134 can be pre-assembled onto the supporting blade 120 or the fixing mechanism 110. During the docking process of the guide rail 131 and the guide groove 132, the positioning pin 133 can be manually lifted to prevent the positioning pin 133 from protruding and affecting the docking of the guide rail 131 and the guide groove 132. After the docking is completed, the positioning pin 133 can be inserted into the corresponding positioning hole.

[0061] S2. Disassembly Method

[0062] When the support blade 120 is dirty or has residual debris that needs to be cleaned, the positioning pin 133 is lifted, thereby causing the positioning pin 133 to release its positioning of the support blade 120 and the fixing mechanism 110, and the support blade 120 slides off the fixing mechanism 110, thus completing the disassembly of the support blade 120 and the fixing mechanism 110.

[0063] The second aspect of this application provides a sheet flipping and conveying device, such as... Figure 4 As shown, the sheet flipping and conveying device includes a flipping frame 200, a flipping shaft 300, and a flipping disk 100 as described in the first aspect.

[0064] The tilting frame 200 is used to place the tilting shaft 300 and related driving components, such as a drive motor, to drive the tilting shaft 300 to rotate. At least two tilting discs 100 are spaced apart on the tilting shaft 300. The fixing mechanism 110 has a shaft hole 112 at its center, through which the tilting shaft 300 passes to drive the tilting discs 100 to rotate.

[0065] It is understood that the spacing between the supporting blades 120 on the flipping disk 100 is used to clamp the sheet body. The two flipping disks 100 are used to achieve stable clamping of the sheet body, thereby satisfying the requirement that the sheet body flips under the action of the two flipping disks 100. Those skilled in the art can reasonably set the spacing between the two flipping disks 100 and the spacing between the two supporting blades 120 in the flipping disk 100 according to the size of the sheet body.

[0066] In summary, this application, based on the engagement connection between the supporting blade 120 and the fixing mechanism 110 achieved by the guide rail 131 and guide groove 132, further utilizes the positioning pin 133 in conjunction with the elastic element 134 to achieve the positioning of the supporting blade 120 and the fixing mechanism 110, ensuring a stable connection between the supporting blade 120 and the fixing mechanism 110. Specifically, in the fixed state, the positioning pin 133, under the elastic force applied by the elastic element 134, simultaneously inserts into the first positioning hole 111 in the supporting blade 120 and the second positioning hole 121 on the fixing mechanism 110, thus achieving the connection between the supporting blade 120 and the fixing mechanism 110. In the disassembled state, manually lifting the positioning pin 133, resisting the elastic force of the elastic element 134, causes the positioning pin 133 to disengage from either the first positioning hole 111 or the second positioning hole 121, thereby canceling the positioning of the supporting blade 120 and the fixing mechanism 110, and the engagement and fixing of the supporting blade 120 and the fixing mechanism 110 by sliding the guide groove 132 and guide rail 131 is released. This application enables the rapid disassembly of the support blade 120 in the flip plate 100, improving replacement efficiency and meeting the requirements for disassembly in confined spaces.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
