[0034] The technical solutions provided by the embodiments of the present application will be described below with reference to the accompanying drawings.
[0035] Referring to Figures 1-3 As shown in the drawings, the present application provides a turnover jig 100, which includes a first carrier plate 110, a second carrier plate 120 and a rotating assembly 130. The rotating assembly 130 connects the first carrier plate 110 and the second carrier plate 120, and is used to drive the first carrier plate 110 and the second carrier plate 120 to rotate relative to each other. The turnover jig 100 is used to turn over a product to be turned over, so as to perform a turnover operation on the product to be turned over, or perform a turnover test on the product to be turned over. Exemplarily, if the product to be turned over is a display module (flexible screen or folding screen), the product to be turned over has a first part and a second part, and the first part and the second part can be folded and turned over. The first part of the product to be turned over is placed on the first carrier plate 110, and the second part of the product to be turned over is placed on the second carrier plate 120. The rotating assembly 130 drives the first carrier plate 110 and the second carrier plate 120 to rotate relative to each other, so as to perform a turnover operation on the product to be turned over.
[0036] The rotating assembly 130 comprises a driving wheel set 131, a driven wheel set 132 and a plurality of transmission shafts 133. The driving wheel set 131 comprises a plurality of first gears 1311 arranged in sequence, and adjacent two first gears 1311 are in meshing with each other. The first gears 1311 can be cylindrical gears, bevel gears or bevel gears. The driven wheel set 132 comprises a plurality of second gears 1321 arranged in sequence, and adjacent two second gears 1321 are in meshing with each other. The second gears 1321 can be cylindrical gears, bevel gears or bevel gears. As shown in the example, Figure 2 The driving wheel set 131 and the driven wheel set 132 are arranged side by side. The first gears 1311 and the second gears 1321 are connected with the transmission shafts 133. It should be noted that since there are a plurality of first gears 1311 and a plurality of second gears 1321, the transmission shafts 133 are connected between the first gears 1311 and the corresponding second gears 1321. One of the first gears 1311 is drivingly connected to the first carrier plate 110 or the second carrier plate 120. When an external force is applied to the first carrier plate 110 or the second carrier plate 120, the first carrier plate 110 or the second carrier plate 120 drives the first gear 1311 to rotate. Since adjacent two first gears 1311 are in meshing with each other, the plurality of first gears 1311 can be synchronously meshed and rotated during the rotation of the first gear 1311. Since the first gears 1311 and the second gears 1321 are connected with the transmission shafts 133, the first gears 1311 transmit power to the second gears 1321, and the plurality of second gears 1321 are meshed and rotated to drive the first carrier plate 110 and the second carrier plate 120 to rotate relative to each other, thereby performing the overturning operation on the product to be overturned.
[0037] The overturning jig 100 provided in the present application is characterized in that the driving wheel set 131 and the driven wheel set 132 are synchronously rotated, the plurality of first gears 1311 have a plurality of meshing angles, the plurality of second gears 1321 also have a plurality of meshing angles, the plurality of first gears 1311 and the plurality of second gears 1321 are linked to control the overturning angle of the first carrier plate 110 and the second carrier plate 120, so that the rotation fitting curve of the first carrier plate 110 and the second carrier plate 120 during the rotation has a plurality of angles, thereby improving the overturning angle control precision of the first carrier plate 110 and the second carrier plate 120. Moreover, the meshing force of the plurality of first gears 1311 and the plurality of second gears 1321 improves the support reliability of the rotating assembly 130 for the first carrier plate 110 and the second carrier plate 120, thereby avoiding the adverse phenomenon of shaking of the overturning jig 100 during the overturning process.
[0038] As shown in the example, Figure 3As shown, the driving wheel set 131 includes four first gears 1311, and the driven wheel set 132 includes three second gears 1321. Among them, the four first gears 1311 are meshed with each other in pairs, the four first gears 1311 have three meshing angles, the three second gears 1321 are meshed with each other in pairs, and the three second gears 1321 have two meshing angles. Through the synchronous rotation of the driving wheel set 131 and the driven wheel set 132, the first carrier plate 110 and the second carrier plate 120 can have five meshing angles in the rotation process, so as to improve the control precision of the turning angle of the first carrier plate 110 and the second carrier plate 120. Of course, in other feasible embodiments, the number of the first gears 1311 included in the driving wheel set 131 and the number of the second gears 1321 included in the driven wheel set 132 can also be other numbers, and the specific number of the first gears 1311 and the second gears 1321 is not limited in the present application.
[0039] In an embodiment, referring to Figures 1-3 As shown, the two first gears 1311 are respectively drivingly connected to the first carrier plate 110 and the second carrier plate 120. In this way, the operator can exert a force on at least one of the first carrier plate 110 and the second carrier plate 120, the first carrier plate 110 and / or the second carrier plate 120 can drive the first gears 1311 to rotate, thereby driving the driving wheel set 131 and the driven wheel set 132 to rotate synchronously, and the driving wheel set 131 and the driven wheel set 132 are linked to control the turning angle of the first carrier plate 110 and the second carrier plate 120, thereby improving the control precision of the turning angle of the first carrier plate 110 and the second carrier plate 120.
[0040] Specifically, referring to Figures 1-3 As shown, the first gear 1311 close to the first carrier plate 110 is drivingly connected to the first carrier plate 110, and the first gear 1311 close to the second carrier plate 120 is drivingly connected to the second carrier plate 120. Exemplarily, referring to Figure 2 and Figure 3 As shown, the two first gears 1311 arranged outside the driving wheel set 131 are respectively connected to the first carrier plate 110 and the second carrier plate 120, a force can be exerted on the first carrier plate 110 and / or the second carrier plate 120 to drive the driving wheel set 131 and the driven wheel set 132 to rotate synchronously, and the driving wheel set 131 and the driven wheel set 132 are linked to control the turning angle of the first carrier plate 110 and the second carrier plate 120, thereby improving the control precision of the turning angle of the first carrier plate 110 and the second carrier plate 120.
[0041] Exemplarily, referring to Figure 4As shown, the turnover fixture 100 is in the unfolded state, i.e. the first carrier plate 110 and the second carrier plate 120 are mutually at an angle of 180°. When the operator applies a force to the first carrier plate 110 and / or the second carrier plate 120, the first carrier plate 110 and the second carrier plate 120 drive the driving wheel set 131 and the driven wheel set 132 to rotate synchronously, so that the first carrier plate 110 and the second carrier plate 120 move towards each other to the folded state as shown. Figure 1 As shown, the turnover fixture 100 is in the unfolded state, i.e. the first carrier plate 110 and the second carrier plate 120 are mutually at an angle of 180°. When the operator applies a force to the first carrier plate 110 and / or the second carrier plate 120, the first carrier plate 110 and the second carrier plate 120 drive the driving wheel set 131 and the driven wheel set 132 to rotate synchronously, so that the first carrier plate 110 and the second carrier plate 120 move towards each other to the folded state as shown. Figure 4 As shown, the turnover fixture 100 is in the unfolded state, i.e. the first carrier plate 110 and the second carrier plate 120 are mutually at an angle of 180°. When the operator applies a force to the first carrier plate 110 and / or the second carrier plate 120, the first carrier plate 110 and the second carrier plate 120 drive the driving wheel set 131 and the driven wheel set 132 to rotate synchronously, so that the first carrier plate 110 and the second carrier plate 120 move towards each other to the folded state as shown.
[0042] Further, referring to Figures 1-3 As shown, the driving wheel set 131 further comprises a first connecting member 1312 and a second connecting member 1313. The first connecting member 1312 is used to connect one of the first gears 1311 and the first carrier plate 110, for example, the first connecting member 1312 is a plate structure, one end of the first connecting member 1312 is connected to the first gear 1311, and the other end of the first connecting member 1312 is connected to the first carrier plate 110. The second connecting member 1313 is used to connect the other first gear 1311 and the second carrier plate 120, for example, the second connecting member 1313 is a plate structure, one end of the second connecting member 1313 is connected to the first gear 1311, and the other end of the second connecting member 1313 is connected to the second carrier plate 120. In this way, the connection between the rotating assembly 130 and the first carrier plate 110 and the second carrier plate 120 can be achieved through the first connecting member 1312 and the second connecting member 1313. When the operator applies a force to the first carrier plate 110 and / or the second carrier plate 120, the first carrier plate 110 drives the first gear 1311 to rotate through the first connecting member 1312, and / or the second carrier plate 120 drives the first gear 1311 to rotate through the second connecting member 1313, to drive the driving wheel set 131 and the driven wheel set 132 to rotate synchronously. The driving wheel set 131 and the driven wheel set 132 are linked to control the folding angle of the first carrier plate 110 and the second carrier plate 120, and improve the folding angle control precision of the first carrier plate 110 and the second carrier plate 120.
[0043] In an embodiment, referring to Figures 1-3As shown, the turnover jig 100 comprises two rotating assemblies 130 and a bending portion 140. The two rotating assemblies 130 are arranged between the first carrier plate 110 and the second carrier plate 120, and the two rotating assemblies 130 are located on opposite sides of the first carrier plate 110, and the bending portion 140 connects the two rotating assemblies 130. In this way, the two rotating assemblies 130 are connected by the bending portion 140, so that the two rotating assemblies 130 rotate synchronously, which can improve the stability of the first carrier plate 110 and the second carrier plate 120 during the turnover process.
[0044] Specifically, referring to Figure 2 and Figure 3 As shown, the bending portion 140 comprises a plurality of rotating shafts 141 and a plurality of connecting rods 142. The rotating shafts 141 extend along the rotation axes of the first carrier plate 110 and the second carrier plate 120, the plurality of rotating shafts 141 are arranged in a radial direction, and the connecting rods 142 are arranged between adjacent two rotating shafts 141, and the two ends of the rotating shaft 141 are respectively inserted into the two second gears 1321 opposite to each other. In this way, the two rotating assemblies 130 can be linked by the rotating shaft 141, and when any one rotating assembly 130 rotates, the two rotating assemblies 130 rotate synchronously by the rotating shaft 141, so as to improve the stability of the first carrier plate 110 and the second carrier plate 120 during the turnover process, and the rotating shaft 141 and the connecting rod 142 can form a curved profile during the rotation process, so as to fit the turnover angle curve of the first carrier plate 110 and the second carrier plate 120, and improve the turnover angle control precision of the first carrier plate 110 and the second carrier plate 120. Moreover, the rotating shaft 141 and the connecting rod 142 can support the first carrier plate 110 and the second carrier plate 120, further improve the turnover stability of the first carrier plate 110 and the second carrier plate 120, and avoid the adverse phenomenon of shaking of the first carrier plate 110 and the second carrier plate 120 during the turnover process.
[0045] In an embodiment, referring to Figure 1As shown, the first carrier plate 110 and the second carrier plate 120 are attached to the product to be flipped by the adhesive, and / or the flipping part of the product to be flipped is attached to the plurality of connecting rods 142 by the adhesive. For example, in one embodiment, the product to be flipped is attached to the first carrier plate 110 and the second carrier plate 120 by the pull-tab adhesive at the edge of the product to be flipped, so that the product to be flipped is better attached to the first carrier plate 110 and the second carrier plate 120, and the product to be flipped is easier to take and replace. For another example, in another embodiment, the product to be flipped has a flipping part between the first part and the second part, the flipping part of the product to be flipped can be folded, and the flipping part of the product to be flipped is attached to the plurality of connecting rods 142 by the pull-tab adhesive, the connecting rods 142 can drive the flipping part of the product to be flipped to fold during rotation, limit the folding path of the flipping part of the product to be flipped, and ensure the determinacy of the flipping path of the product to be flipped. For another example, in another embodiment, the first carrier plate 110 and the second carrier plate 120 are attached to the product to be flipped by the adhesive, and the flipping part of the product to be flipped is attached to the plurality of connecting rods 142 by the adhesive, which can limit the folding path of the flipping part of the product to be flipped on the basis of ensuring the reliable attachment of the product to be flipped to the first carrier plate 110 and the second carrier plate 120.
[0046] During the flipping of the product to be flipped, part of the structure of the product to be flipped will be bent, which will cause the product to be flipped to be subjected to tensile stress of the first carrier plate 110 or the second carrier plate 120 during the flipping, and then cause the product to be flipped to deform, crack, or other adverse phenomena during the flipping. Based on this, in one embodiment, referring to Figure 1 With Figure 5 As shown, the first carrier plate 110 and the second carrier plate 120 each include a base 150 and a carrier table 160. In this embodiment, the first carrier plate 110 and the second carrier plate 120 have the same structure, the first carrier plate 110 includes the base 150 and the carrier table 160, and the second carrier plate 120 also includes the base 150 and the carrier table 160. The carrier table 160 is used to carry the product to be flipped, and the carrier table 160 is slidingly arranged on the base 150. For example, the carrier table 160 includes a connecting seat 161 and a carrying seat 162 arranged in layers, the connecting seat 161 is slidingly arranged on the base 150, and the carrying seat 162 is provided with a carrying cavity. The product to be flipped is placed in the carrying cavity to complete the feeding operation of the product to be flipped.
[0047] The above-mentioned flipping jig 100 can slide the carrier table 160 relative to the base 150 during the flipping of the product to be flipped, so as to compensate for the bending displacement of the product to be flipped, eliminate the tensile stress of the product to be flipped caused by the first carrier plate 110 or the second carrier plate 120 during the flipping, and avoid the deformation, cracking, or other adverse phenomena of the product to be flipped during the flipping.
