In the folding process, once the flexible connecting portion 13 is subjected to a large pulling force, the substrate 11a and the cover plate 11b are easily separated, or the signal line on the flexible connecting portion 13 is broken, so that the device to be folded is not good after being folded.

Fig. 4 is a schematic view of an initial state of a folding apparatus provided in some embodiments of the present disclosure, fig. 5 is a schematic view of the folding apparatus provided in some embodiments of the present disclosure when a device to be folded is folded, and fig. 6 is a schematic view of the folding apparatus provided in some embodiments of the present disclosure after the device to be folded is folded, as shown in fig. 4 to fig. 6, the folding apparatus includes: a base 20, a carrying mechanism 30 and a turnover mechanism 40. The base 20 may be made of a relatively rigid material, such as stainless steel. The base 20 may have a plate-like structure or a frame-like structure with a hollow portion. The supporting mechanism 30 is disposed on the base 20, and the supporting mechanism 30 has a supporting surface for supporting the main body 11 of the device 10 to be folded. For example, the support mechanism 30 may fix the main body 11 on the support surface by vacuum suction.

The folding mechanism 40 is located on at least one side of the bearing mechanism 30, the folding mechanism 40 is rotatably connected with the bearing mechanism 30 through a first rotating shaft 51 and is used for bearing and fixing the portion to be folded 12, and the folding mechanism 40 is further used for turning around the axis of the first rotating shaft 51 so as to fold the portion to be folded 12 to one side of the main body portion 11 away from the bearing mechanism 30. The distance from the axis of the first rotating shaft 51 to the base 20 is less than or equal to the sum of the distance from the bearing surface to the base 20 and the thickness of the cover plate 11b of the device to be folded 10.

The device 10 to be folded may include one portion 12 to be folded, or may include two portions 12 to be folded. Taking the example that the device to be folded 10 includes two portions to be folded 12, the two portions to be folded 12 are respectively located at two opposite sides of the main body portion 11. The number of the folding mechanisms 40 may be one, or may be multiple, when the number of the folding mechanisms 40 is two, two folding mechanisms 40 may be disposed on two opposite sides of the carrying mechanism 30, and the two folding mechanisms 40 may be respectively used for carrying two portions to be folded 12. Alternatively, each folding mechanism 40 is connected to the supporting mechanism 30 through two first rotating shafts 51, and the two first rotating shafts 51 connected to the same folding mechanism 40 are coaxially disposed and located on two opposite sides of the supporting mechanism 30.

In order to fold the device 10 to be folded into the state shown in fig. 3, when the main body 11 is fixed to the supporting mechanism 30, the cover plate 11b of the main body 11 may be disposed toward the supporting mechanism 30, so that the base plate of the main body 11 is located on the side of the cover plate away from the supporting mechanism 30, and after the folding mechanism 40 is turned around the axis of the first rotating shaft 51, the part 12 to be folded is located on the side of the base plate 11a of the main body 11 away from the cover plate 11 b. Because the distance from the axis of the first rotating shaft 51 to the base 20 is less than or equal to the sum of the distance from the bearing surface to the base 20 and the thickness of the cover plate 11b, when the device 10 to be folded is folded, the axis of the first rotating shaft 51 is not higher than the plane of the cover plate 11b, so that the tensile force applied to the flexible connecting part 13 in the folding process can be reduced, the signal wire on the flexible connecting part 13 is prevented from being broken, the base plate 11a of the main body part 11 is prevented from being peeled off from the cover plate 11b, and the product yield is improved.

In some embodiments, the folding mechanism 40 may further include: and the driving mechanism (not shown) is connected with the turnover mechanism 40 and is used for driving the turnover mechanism 40 to turn around the axis of the first rotating shaft 51, so that automatic turnover is realized, and the working efficiency is improved. The drive mechanism may include a motor, such as a lead screw motor.

In some embodiments, as shown in fig. 4 and 5, the folding mechanism 40 includes: a bearing part 41 and a connecting arm 42, wherein the bearing part 41 is used for bearing and fixing the part to be folded 12 of the device to be folded 10. One end of the connecting arm 42 is connected to the bearing mechanism 30 through a first rotating shaft, and the other end is connected to the bearing portion 41 through a second rotating shaft 52, and the first rotating shaft 51 and the second rotating shaft 52 extend in the same direction.

In practical applications, in order to improve the reliability of the product, it is necessary to ensure that after the device 10 to be folded is folded, the flexible connecting portion 13 is in a rounded drop-shaped state (as shown in fig. 3), and when the folding mechanism 40 rotates around the first rotating shaft, the flexible connecting portion 13 is easily wrinkled, so that the signal lines on the flexible connecting portion 13 are easily broken. Fig. 7 and 8 are schematic diagrams of the device to be folded when the flexible connection portion of the device to be folded is wrinkled and is not wrinkled, as shown in fig. 7, during the folding process of the device 10 to be folded, the inner side of the flexible connection portion 13 may be squeezed to wrinkle, in this case, the bearing portion 41 may be controlled to slightly swing around the second rotating shaft 52, so that the position of the flexible connection portion 13 close to the main body portion 11 is subjected to a pulling force F (as shown by an arrow in fig. 7), and a smooth transition state shown in fig. 8 is achieved, so that after the device 10 to be folded is completely folded, the flexible connection portion 13 may form a rounded water droplet shape. The angle range of the swing of the bearing part 41 around the second rotating shaft 52 can be between 0 and 10 degrees, so that the flexible connecting part 13 is prevented from being subjected to overlarge pulling force.

Fig. 9 is a perspective view of a load bearing part provided in some embodiments of the present disclosure, and fig. 10 is a top view of the load bearing part provided in some embodiments of the present disclosure, and as shown in fig. 4, 9, and 10, the load bearing part 41 includes: a frame and a first stage 413 are mounted. The installation frame may specifically include: two first mounting arms 411 arranged oppositely and two second mounting arms 412 arranged oppositely, wherein the two first mounting arms 411 and the two second mounting arms 412 enclose a frame shape, and the first mounting arms 411 are connected with the connecting arm 42 through the second rotating shaft 52.

The first bearing table 413 is installed in the installation frame and is used for bearing and fixing the part to be folded 12 of the device to be folded 10. Alternatively, the first bearing table 413 has a first surface for bearing the part 12 to be folded, a first suction hole V1 is disposed on the first bearing table 413, one end of the first suction hole V1 is located on the first surface of the first bearing table 413, and the other end can be communicated with an air extractor. The first suction hole V1 is sucked by the suction device, so that the portion to be folded 12 can be sucked on the first stage 413. Of course, the portion to be folded 12 may be fixed on the first bearing platform 413 by other means; for example, the portion to be folded 12 is fixed to the first stage 413 by a jig.

In some applications, as shown in fig. 3, in addition to the flexible connecting portion 13 being bent to form a rounded drop shape, it is necessary to ensure that the boundary of the flexible connecting portion 13 cannot exceed the boundary of the cover plate 11b to prevent the flexible connecting portion 11b from being pressed by an external force, but in the actual folding process, the flexible connecting portion 11b is inevitably extended beyond the boundary of the cover plate (as shown in fig. 11).

To solve this problem, as shown in fig. 10, in some embodiments of the present disclosure, a support member 410 and an elastic member 419 are disposed on opposite sides of a first carrier 413. Specifically, one of the two second mounting arms 412 is provided with a mounting hole, and the other one is provided with an elastic member 419, and the axial direction of the mounting hole is the same as the extending direction of the first mounting arm 411. The support 410 is inserted into the mounting hole for axial movement along the mounting hole. Wherein one end of the support 410 abuts on the first stage 413. The elastic member 419 and the supporting member 410 are respectively disposed on two opposite sides of the first supporting platform 413, one end of the elastic member 419 is connected to the first supporting platform 413, and the other end is connected to the second mounting arm 412 far from the supporting member 410.

In one example, the support 410 is a screw and the mounting hole is a threaded hole that mates with the support 410. The elastic member 419 is a compression spring, wherein the compression spring is in a compressed state, so as to continuously apply an urging force to the first loading stage 413. A mounting groove may be provided on the first bearing table 413, and a portion of the elastic member 419 may extend into the mounting groove, thereby improving the mounting stability of the elastic member 419.

After the portion to be folded 12 is folded to the side of the main body 11 away from the bearing mechanism 30, if the flexible connecting portion 13 exceeds the boundary of the cover plate 11b, the supporting member 410 can be moved toward or away from the first bearing platform 413 by rotating the supporting member 410, so that the first bearing platform 413 is moved along the extending direction of the first mounting arm 411, and the portion to be folded 12 is moved along the extending direction of the first mounting arm 411 until the flexible connecting portion 13 does not exceed the boundary of the cover plate 11 b.

The number of the supporting members 410 and the elastic members 419 is not limited in the embodiment of the present disclosure, for example, as shown in fig. 10, in each folding mechanism 40, the number of the supporting members 410 is one, and the supporting members 410 are disposed at the middle position of the second mounting arm 412; the number of the elastic members 419 is two, and the two elastic members 419 are respectively disposed at positions close to the two first mounting arms 411. Of course, the supporting members 410 and the elastic members 419 may be provided in other numbers.

Further, as shown in fig. 10, the bearing part 41 may further include: a stage mount 414 and a guide 415. It should be noted that the stage mount 414 can be made of an opaque material, such as metal, and the stage mount 414 is shown with some transparency in fig. 10 only to illustrate the structure inside the stage mount 414 more clearly. The guide 415 is connected between the two second mounting arms 412 and extends in the extending direction of the first mounting arm 411. The stage mount 414 is slidably disposed on the guide 415 for translation relative to the guide 415 in a direction of extension of the guide 415. The stage mount 414 is fixedly connected to the first stage 413, for example, by fasteners 418 such as screws. By providing the guide 415, the moving direction of the first stage 413 can be prevented from being inclined.

The specific structure of the guide 415 is not limited in the embodiment of the present disclosure, for example, the guide 415 may be a guide rail, a slider is slidably disposed on the guide rail, and the plummer installation part 414 is fixedly connected to the slider.

The first rotating shaft 51 is disposed on the mounting seat 32, and the folding mechanism 40 is rotatably connected to the mounting seat 32 through the first rotating shaft 51.

The second platform 31 includes a plurality of sub-platforms 311 disposed on the mounting base 32, the sub-platforms 311 are arranged along a first direction, the first direction is a direction in which the supporting mechanism 30 points to the folding mechanism 40, and it should be noted that "the direction in which the supporting mechanism 30 points to the folding mechanism 40" means a direction in which the supporting mechanism 30 points to the folding mechanism 40 before the folding mechanism 40 is not folded. Each sub-carrier 311 has a sub-carrier surface, and the sub-carrier surfaces of the sub-carriers 311 together form a carrier surface of the carrier mechanism 30. In addition, the distance between the two sub-bearing tables 311 with the farthest distance is adjustable, so that the second bearing table 31 can bear the devices 10 to be folded with different sizes.

In one example, as shown in fig. 4, the second stage 31 includes two sub-stages 311. The orthogonal projection of the sub-platform 311 on the plane of the base 20 may be rectangular or polygonal.
