Description

Technical Field

[0001] The present invention belongs to the technical field of jigs, and more specifically, relates to a bending jig driving device and a bending jig system. Background Art

[0002] Folding screen mobile phones have a structure similar to that of hinges and can be bent. Before the folding module leaves the factory, it is necessary to observe the water drop bending area, compare the actual water drop morphology with the simulated water drop morphology, and observe the displacement of each stack of the folding module to evaluate the bending performance of the folding module material. When the folding module is bent, the folding module can be placed on a bending jig, and the bending jig can be bent to achieve the bending of the folding module. However, the current drive device used to drive the bending jig is prone to jamming and unsmoothness during use, and may even damage the bending jig. Summary of the invention

[0003] The purpose of the embodiments of the present invention is to provide a bending jig driving device and a bending jig system to solve the technical problem in the prior art that the bending jig driving device is prone to jamming or even damaging the bending jig during use.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide a bending jig driving device for driving the bending jig to bend, the bending jig includes a first rotating plate and a second rotating plate that can rotate relative to each other, the bending jig driving device includes a first fixed structure fixedly connected to the first rotating plate, a driving member, a swinging structure driven to rotate by the driving member, a compensation structure slidably connected to the swinging structure, and a second fixed structure fixedly connected to the second rotating plate, the compensation structure being rotatably connected to the second fixed structure.

[0005] In the above scheme, the bending jig driving device includes a first fixed structure, a second fixed structure, a driving member, a swinging structure and a compensation structure. The first fixed structure and the second fixed structure are respectively used to be fixed on the first rotating plate and the second rotating plate of the bending jig. The driving member is used to drive the swinging structure to swing. The swinging of the swinging structure can drive the second rotating plate to rotate relative to the first rotating plate to achieve bending of the bending jig. Moreover, the swinging structure is slidably connected to the compensation structure, and the compensation structure is rotationally connected to the second fixed structure. Therefore, when the swinging structure rotates, the swinging structure can slide relative to the compensation structure, and the compensation structure can rotate relative to the second fixed structure, which can reduce the jamming of the bending jig driving device during use to avoid damage to the bending jig.

[0006] Optionally, the compensation structure includes a rotation compensation member rotatably connected to the second fixed structure and a sliding compensation portion slidably connected to the swing structure, and the sliding compensation portion is arranged on the rotation compensation member.

[0007] In the above scheme, when the driving member drives the swinging structure to drive the second fixed structure (second rotating plate) to rotate relative to the first fixed structure (second rotating plate), the sliding compensation part slides relative to the swinging structure to compensate for the displacement difference between the swinging structure and the second fixed structure, and the rotating compensation part rotates relative to the second fixed structure to compensate for the angle difference between the swinging structure and the second fixed structure. Therefore, the transmission connection between the swinging structure and the second fixed structure can be made smoother and the jamming phenomenon can be reduced.

[0008] Optionally, the rotational compensation member includes a connecting rod and an arc portion, the connecting rod is connected to the second fixed structure, the arc portion has an arc surface for abutting against the second fixed structure, and the central axis of the arc surface coincides with the rotational central axis of the rotational compensation member.

[0009] In the above scheme, the arc-shaped portion and the second fixed structure are arranged to abut against each other, so that the rotation of the rotation compensation member relative to the second fixed structure is the rolling of the arc-shaped portion on the second fixed structure. Therefore, the movement of the rotation compensation member is smoother, and compared with rotation connection methods such as hinge connection, the rotation compensation member will not shake, and the rotation of the second rotating plate is also smoother.

[0010] Optionally, a hinged portion is protruded from a side of the second fixing structure facing the rotation compensation member, the connecting rod passes through the hinged portion, and the number of the arc-shaped portions is two, which are respectively arranged at both ends of the connecting rod.

[0011] In the above scheme, the hinged portion is provided so that the connecting rod and the second fixed structure are spaced apart, and the arc surface of the arc portion fixed on the connecting rod has sufficient arrangement space. Moreover, there are two arc portions, so that there are two contact positions between the rotation compensation member and the second fixed structure, thereby making the rolling of the rotation compensation member on the second fixed structure more stable.

[0012] Optionally, the swing structure is provided with a sliding groove, and the sliding compensation portion is in a rod shape and is disposed through the sliding groove.

[0013] In the above solution, the sliding compensation part is a sliding structure, and correspondingly, a sliding groove is provided on the swing structure, thereby realizing a sliding connection between the swing structure and the compensation structure.

[0014] Optionally, the sliding direction of the swing structure relative to the compensation structure is perpendicular to the rotation axis of the swing structure, and the rotation axis of the compensation structure relative to the second fixed structure is parallel to the rotation axis of the swing structure.

[0015] In the above scheme, the sliding direction of the swing structure relative to the compensation structure is perpendicular to the rotation axis of the swing structure, which can compensate for the displacement difference between the swing structure and the second fixed structure in the sliding direction; the rotation axis of the compensation structure relative to the second fixed structure is parallel to the rotation axis of the swing structure, which can compensate for the angle difference when the swing structure and the second fixed structure rotate around the rotation axis.

[0016] Optionally, the swing structure includes a swing rod and a sliding rod, one end of the swing rod is connected to the motion output end of the driving member, the other end of the swing rod is connected to the sliding rod, and the sliding rod is slidably arranged on the compensation structure.

[0017] In the above solution, the swing rod is arranged to keep the sliding rod away from the motion output end of the driving member, thereby making the motion path of the sliding rod close to the motion paths of the second fixed structure and the second rotating plate.

[0018] Optionally, the length direction of the sliding rod is parallel to the rotation center axis of the swing structure.

[0019] In the above scheme, when the swing structure rotates, the movement path of the sliding rod is cylindrical, which is the same as the movement path of the second rotating plate, and is more matched with the movement path of the second rotating plate, thereby reducing jamming and reducing the structural complexity of the compensation structure.

[0020] Optionally, the sliding rod is provided with a sliding groove for the compensation structure to pass through, and the sliding groove passes through two sides of the sliding rod along the sliding direction of the swing structure.

[0021] In the above solution, both ends of the sliding compensation part of the compensation structure can extend out of the sliding groove and be connected to the arc-shaped part of the compensation structure. In this way, the swing structure can be limited to prevent the swing structure and the compensation structure from falling off from each other.

[0022] The present invention also provides a bending jig driving device for driving the bending jig to bend, wherein the bending jig comprises a first rotating plate and a second rotating plate capable of rotating relative to each other, comprising:

[0023] a first fixing structure for fixedly connecting to the first rotating plate;

[0025] A swing structure driven to rotate by the driving member;

[0026] A sliding compensation portion slidably connected to the swing structure;

[0027] a second fixing structure for fixedly connecting to the second rotating plate;

[0028] The rotation compensation member comprises a connecting rod and an arc portion, wherein the arc portion is fixed to the sliding compensation portion, and the connecting rod is rotationally connected to the arc portion; the second fixing structure is provided with a hinge portion, and the connecting rod is fixedly connected to the hinge portion.

[0029] The present invention also provides a bending jig system, comprising a bending jig, a shooting camera and the above-mentioned bending jig driving device, wherein the bending jig driving device is used to drive the first rotating plate and the second rotating plate of the bending jig to rotate relative to each other, and the shooting camera is used to shoot the side of the bending part of the bending jig.

[0030] In the above scheme, the folding module is placed on a bending jig. When the bending jig is installed on a bending jig driving device, the bending jig driving device works, and the second rotating plate of the bending jig can rotate relative to the first rotating plate. Accordingly, the folding module is folded, and the shooting camera can record the shape of the bending part of the bending jig (the connection part of the first rotating plate and the second rotating plate) and the folding part of the folding module, as well as the displacement of each layer of the folding module.

DETAILED DESCRIPTION

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0044] The structure of a folding screen mobile phone is similar to that of a hinge and can be bent. Before the folding module leaves the factory, it is necessary to observe the water drop bending area, compare the actual water drop morphology with the simulated water drop morphology, and observe the displacement of each stack of the folding module to evaluate the bending performance of the folding module material. When performing a bending test on the folding module, the folding module can be placed on a bending jig, and the bending jig can be bent to achieve the bending of the folding module.

[0045] Some manufacturers use manual bending jigs to bend the bending jigs, but the folding module needs to be tested multiple times, so the workload is large. Some manufacturers use a driving device to drive the bending jig to bend. When the driving device drives the bending jig to bend and flip, the moving end of the driving device and the rotating plate of the bending jig cannot be completely synchronized, which causes the driving device to jam and become unsmooth when driving the bending jig to bend and flip, and even damage the bending jig.

[0046] In order to alleviate or solve the above technical problems, the present invention proposes a bending jig driving device, including a first fixed structure 151, a driving member 11, a swinging structure 12, a compensation structure 13 and a second fixed structure 152. The first fixed structure 151 and the second fixed structure 152 are respectively fixed to two mutually rotating plates of the bending jig 20. The driving member 11 drives the swinging structure 12 to swing, and the compensation structure 13 can compensate for the displacement or angle between the swinging structure 12 and the second fixed structure 152, thereby making the bending and flipping of the bending jig 20 smoother to avoid jamming or damage to the jig.

[0047] The bending jig driving device provided in the embodiment of the present invention is now described. The bending jig driving device is used to drive the bending jig 20 to bend and flip. A folding module is placed on the bending jig 20, so that the water drop morphology of the folding module when folding and the displacement of each layer of the folding module can be observed. Among them, the bending jig 20 includes a first rotating plate 21 and a second rotating plate 22 that are rotatably connected to each other, and the function of the bending jig driving device is to make the first rotating plate 21 and the second rotating plate 22 rotate relative to each other.

[0048] Please also read Figures 1 to 3 The bending jig driving device includes a first fixed structure 151 fixedly connected to the first rotating plate 21, a driving member 11, a swinging structure 12 driven to rotate by the driving member 11, a compensation structure 13 slidingly connected to the swinging structure 12, and a second fixed structure 152 fixedly connected to the second rotating plate 22, and the compensation structure 13 is rotationally connected to the second fixed structure 152.

[0049] The first fixed structure 151 is fixedly arranged. The first fixed structure 151 may be a plate-like structure, a bracket-like structure, etc., and its specific structural shape is not limited here. The first fixed structure 151 is used to be fixedly connected to the first rotating plate 21 of the bending jig 20. It can also be understood that the first rotating plate 21 of the bending jig 20 is supported and fixed on the first fixed structure 151, and accordingly, the first rotating plate 21 is also fixedly arranged.

[0050] The driving member 11 is a power device that can output rotational motion and drive the second rotating plate 22 to rotate relative to the first rotating plate 21 through the transmission of the swing structure 12, the compensation structure 13 and other structures. The driving member 11 can be a motor, a steering gear and other structures.

[0051] The swing structure 12 is driven to rotate by the driving member 11. Specifically, the motion output end of the driving member 11 is fixedly connected to the swing structure 12. When the driving member 11 is working, the swing structure 12 rotates with the driving member 11. The swing structure 12 can be an integrally formed structure or a structure composed of separate parts that are connected to each other.

[0052] The compensation structure 13 is used to compensate for the position difference and angle difference between the swing structure 12 and the second rotating plate 22 when the second rotating plate 22 rotates relative to the first rotating plate 21, so as to avoid interference between the swing structure 12 and the second rotating plate 22 when the bending jig driving device is working, resulting in jamming or damage to the bending jig 20. Specifically, the compensation structure 13 is slidably connected to the swing structure 12, and the compensation structure 13 is rotatably connected to the second fixed structure 152, so that when the first rotating plate 21 rotates relative to the second rotating plate 22, the compensation structure 13 can compensate for the position difference and angle difference between the swing structure 12 and the second rotating plate 22.

[0053] The second fixing structure 152 is used to be fixed to the second rotating plate 22 . When the second rotating plate 22 flips relative to the first rotating plate 21 , the second fixing structure 152 moves synchronously with the second rotating plate 22 .

[0054] It should be noted that, in the bending jig 20, the first rotating plate 21 and the second rotating plate 22 rotate relative to each other and approach to a folded state. In the folded state, the larger exposed side of the first rotating plate 21 is the first fixed side, and the larger exposed side of the second rotating plate 22 is the second fixed side. The first fixed structure 151 is fixed to the first fixed side of the first rotating plate 21, and the second fixed structure 152 is fixed to the second fixed side of the second rotating plate 22.

[0055] The bending jig driving device in the above embodiment includes a first fixed structure 151, a second fixed structure 152, a driving member 11, a swinging structure 12 and a compensation structure 13. The first fixed structure 151 and the second fixed structure 152 are respectively used to be fixed on the first rotating plate 21 and the second rotating plate 22 of the bending jig 20. The driving member 11 is used to drive the swinging structure 12 to swing. The swinging of the swinging structure 12 can drive the second rotating plate 22 to rotate relative to the first rotating plate 21, thereby achieving bending of the bending jig 20. Moreover, the swinging structure 12 is slidably connected to the compensation structure 13, and the compensation structure 13 is rotatably connected to the second fixed structure 152. Therefore, when the swinging structure 12 rotates, the swinging structure 12 can slide relative to the compensation structure 13, and the compensation structure 13 can rotate relative to the second fixed structure 152, which can reduce the jamming of the bending jig driving device during use to avoid damaging the bending jig 20.

[0056] In some embodiments of the present invention, see Figure 2 and Figure 3 The compensation structure 13 includes a rotation compensation member 132 that is rotationally connected to the second fixed structure 152 and a sliding compensation portion 131 that is slidingly connected to the swing structure 12, and the sliding compensation portion 131 is arranged on the rotation compensation member 132. The rotation compensation member 132 can rotate relative to the second fixed structure 152, thereby compensating for the angle difference between the swing structure 12 and the second fixed structure 152. Specifically, when the second fixed structure 152 rotates with the second rotating plate 22, the swing structure 12 rotates at an angle A, and the second fixed structure 152 and the second rotating plate 22 rotate at an angle B. Since the second fixed structure 152 is located at the end of the transmission chain, the rotation is relatively lagging, so generally speaking, A is greater than B. If the swing structure 12 and the second fixed structure 152 are directly connected, it will cause a jamming phenomenon. By setting the rotation compensation member 132, the angle difference between the swing structure 12 and the second fixed structure 152 can be compensated, and the transmission connection is more stable. The sliding compensation part 131 is slidably connected to the swing structure 12. When the swing structure 12 rotates, the end of the swing structure 12 close to the second fixed structure 152 will be offset from the second fixed structure 152. The setting of the sliding compensation part 131 can make up for the displacement difference between the end of the swing structure 12 close to the second fixed structure 152 and the second fixed structure 152. Specifically, when the swing structure 12 rotates, the sliding compensation part 131 will slide relative to the swing structure 12, changing the relative position between the compensation structure 13 and the swing structure 12, so that the transmission connection is smoother.

[0057] When the driving member 11 drives the swinging structure 12 to drive the second fixed structure 152 (second rotating plate 22) to rotate relative to the first fixed structure 151 (second rotating plate 22), the sliding compensation part 131 slides relative to the swinging structure 12 to compensate for the displacement difference between the swinging structure 12 and the second fixed structure 152, and the rotation compensation part 132 rotates relative to the second fixed structure 152 to compensate for the angle difference between the swinging structure 12 and the second fixed structure 152. Therefore, the transmission connection between the swinging structure 12 and the second fixed structure 152 can be made smoother and the jamming phenomenon can be reduced.

[0058] In some embodiments, the swing structure 12 is provided with a sliding groove 1221, and the sliding compensation portion 131 is in a rod shape and is arranged through the sliding groove 1221. In this embodiment, the sliding compensation portion 131 is a sliding structure, and accordingly, the swing structure 12 is provided with a sliding groove 1221, thereby realizing a sliding connection between the swing structure 12 and the compensation structure 13.

[0059] When the swing structure 12 rotates, the sliding compensation portion 131 moves along the sliding groove 1221 to prevent the swing structure 12 from being stuck.

[0060] Optionally, the cross section of the sliding compensation portion 131 has the same shape as the cross section of the sliding groove 1221. For example, the cross section of the sliding compensation portion 131 and the cross section of the sliding groove 1221 are both square, or the cross section of the sliding compensation portion 131 and the cross section of the sliding groove 1221 are both circular.

[0061] Optionally, the sliding compensation part 131 is fixedly connected to the rotation compensation part 132. For example, the sliding compensation part 131 and the rotation compensation part 132 are integrally formed. Alternatively, the sliding compensation part 131 and the rotation compensation part 132 are separately formed and then fixed to each other.

[0062] Optionally, two ends of the sliding compensation portion 131 extend out of the sliding groove 1221 respectively, and are respectively connected to opposite sides of the rotation compensation member 132 (such as the arc-shaped portion 1322) through structures such as connecting sections.

[0063] In some embodiments, a sliding rod 122 is provided on the swing structure 12, and the sliding compensation part 131 is a matching groove. When the swing structure 12 rotates, the rotation compensation part 132 can slide relative to the swing structure 12. In this embodiment, the sliding compensation part 131 is a groove-shaped structure, and the sliding compensation part 131 can be opened on the rotation compensation part 132.

[0064] In some embodiments of the present invention, see Figures 1 to 3The rotation compensating member 132 includes a connecting rod 1321 and an arc portion 1322. The connecting rod 1321 is connected to the second fixed structure 152. The arc portion 1322 has an arc surface 1323 for abutting against the second fixed structure 152. The central axis of the arc surface 1323 coincides with the rotation central axis of the rotation compensating member 132. The connecting rod 1321 is used to connect the second fixed structure 152 and the arc portion 1322. The connecting rod 1321 is a rod-shaped structure. The arc portion 1322 has an arc surface 1323, and the arc surface 1323 abuts against the second fixed structure 152. When the rotation compensating member 132 rotates relative to the second fixed structure 152, the arc surface 1323 rolls on the second fixed structure 152, thereby changing the angle between the rotation compensating member 132 and the second fixed structure 152. The rotation central axis of the rotation compensating member 132 is the rotation central axis of the rotation compensating member 132 relative to the second fixed structure 152. The central axis of the arc surface 1323 coincides with the rotation central axis of the rotation compensation member 132 , so that when the rotation compensation member 132 rotates, each circumferential position of the arc surface 1323 contacts the second fixed structure 152 in sequence, ensuring smooth movement.

[0065] By setting the arc portion 1322 and the second fixed structure 152 to abut against each other, the rotation of the rotation compensation member 132 relative to the second fixed structure 152 is the rolling of the arc portion 1322 on the second fixed structure 152. Therefore, the movement of the rotation compensation member 132 is smoother, and compared with rotation connection methods such as hinge connection, the rotation compensation member 132 will not shake, and the rotation of the second rotating plate 22 is also smoother.

[0066] In some embodiments, the arc portion 1322 is a block structure, and at least a portion of the circumference of the arc portion 1322 is the arc surface 1323 , and the other circumferences of the arc portion 1322 may be arc surfaces or flat surfaces.

[0067] In some embodiments of the present invention, see Figure 2 and Figure 3 , a hinged portion 1521 is provided on the side of the second fixed structure 152 facing the rotation compensation member 132, a connecting rod 1321 is provided through the hinged portion 1521, and there are two arc-shaped portions 1322, which are respectively provided at both ends of the connecting rod 1321. A hinged portion 1521 is provided on the side of the second fixed structure 152 facing the rotation compensation member 132, so as to facilitate the connection between the second fixed structure 152 and the rotation compensation member 132. The connecting rod 1321 is provided through the hinged portion 1521, so that the connecting rod 1321 and the second fixed structure 152 are arranged at intervals, and the arc surface 1323 of the arc-shaped portion 1322 needs to be located between the second fixed structure 152 and the connecting rod 1321, so that the arc surface 1323 can have sufficient design space. The connecting rod 1321 is rotatably connected with the hinged portion 1521.

[0068] By setting the hinged portion 1521, the connecting rod 1321 and the second fixed structure 152 are spaced apart, and the arc surface 1323 of the arc portion 1322 fixed on the connecting rod 1321 has sufficient arrangement space. In addition, there are two arc portions 1322, so that there are two contact positions between the rotation compensation member 132 and the second fixed structure 152, thereby making the rolling of the rotation compensation member 132 on the second fixed structure 152 more stable.

[0069] In some embodiments, the connecting rod 1321 is arranged in a rod shape, and the connecting rod 1321 extends along the length direction of the second fixed structure 152, so that the two arc-shaped portions 1322 are closer to the two ends of the second fixed structure 152 along the length direction, and then can abut against the two ends of the second fixed structure 152 in the length direction, so that the rotation of the rotation compensation member 132 is more stable.

[0070] In some embodiments, the connecting rod 1321 is fixedly connected to the hinge portion 1521, and the arc portion 1322 is rotatably connected to the connecting rod 1321. When the driving member 11 drives the swing structure 12 to rotate, the arc portion 1322 rolls along the second fixed structure 152 driven by the sliding compensation portion 131, and the connecting rod 1321 and the second fixed structure 152 remain relatively fixed. In this embodiment, the connecting rod 1321 passes through the hinge portion 1521, and the connecting rod 1321 and the hinge portion 1521 are fixed to each other, and the function of the connecting rod 1321 is to connect the two arc portions 1322. Among them, one end of the connecting rod 1321 extends into the arc portion 1322, but the arc portion 1322 can rotate relative to the connecting rod 1321.

[0071] In some embodiments, the connecting rod 1321 is rotatably connected to the hinge portion 1521, and the arc portion 1322 is fixedly connected to the connecting rod 1321. When the driving member 11 drives the swing structure 12 to rotate, the arc portion 1322 rolls along the second fixed structure 152 under the drive of the sliding compensation portion 131, and the connecting rod 1321 and the arc portion 1322 move synchronously. In this embodiment, the connecting rod 1321 passes through the hinge portion 1521, but the connecting rod 1321 is movably connected to the hinge portion 1521 and can move relative to the hinge portion 1521.

[0072] In some embodiments of the present invention, see Figures 1 to 3, the sliding direction of the swing structure 12 relative to the compensation structure 13 is perpendicular to the rotation axis of the swing structure 12, and the rotation axis of the compensation structure 13 relative to the second fixed structure 152 is parallel to the rotation axis of the swing structure 12. The rotation axis of the first rotating plate 21 and the second rotating plate 22 in the bending jig 20 is the first rotation axis, and the rotation axis of the swing structure 12 is the second rotation axis, and the first rotation axis and the second rotation axis are both parallel to the first direction. When the swing structure 12 rotates, due to the bending and flipping of the bending jig 20, the swing structure 12 will have a displacement difference with the second fixed structure 152 in the second direction, and the above displacement difference is compensated by the sliding of the sliding compensation part 131 relative to the swing structure 12 in the second direction; at the same time, the swing structure 12 will have an angle difference with the second fixed structure 152 along the first direction, and the above angle difference is compensated by the rotation of the rotation compensation part 132 relative to the second fixed structure 152. Among them, the first direction and the second direction are perpendicular to each other.

[0073] The sliding direction of the swing structure 12 relative to the compensation structure 13 is perpendicular to the rotation axis of the swing structure 12, which can compensate for the displacement difference between the swing structure 12 and the second fixed structure 152 in the sliding direction; the rotation axis of the compensation structure 13 relative to the second fixed structure 152 is parallel to the rotation axis of the swing structure 12, which can compensate for the angle difference when the swing structure 12 and the second fixed structure 152 rotate around the rotation axis.

[0074] In some embodiments, in the bending jig 20, the first rotating plate 21 and the second rotating plate 22 are rotatably connected at their long sides, and accordingly, the first direction is parallel to the long side of the second rotating plate 22 (the length direction of the second rotating plate 22), and the second direction is perpendicular to the long side of the second rotating plate 22 (the length direction of the second rotating plate 22).

[0075] In some embodiments of the present invention, see Figures 2 to 4 The swing structure 12 includes a swing rod 121 and a sliding rod 122. One end of the swing rod 121 is connected to the motion output end of the driving member 11, and the other end of the swing rod 121 is connected to the sliding rod 122. The sliding rod 122 is slidably disposed on the compensation structure 13. When the driving member 11 drives the swing structure 12 to swing, the swing rod 121 and the sliding rod 122 swing synchronously.

[0076] By disposing the swing rod 121 , the sliding rod 122 is moved away from the motion output end of the driving member 11 , so that the motion path of the sliding rod 122 is close to the motion paths of the second fixed structure 152 and the second rotating plate 22 .

[0077] In some embodiments, the length direction of the sliding rod 122 is parallel to the rotation center axis of the swing structure 12. In this way, when the swing structure 12 rotates, the movement path of the sliding rod 122 is cylindrical, which is the same as the movement path of the second rotating plate 22, and is more matched with the movement path of the second rotating plate 22, thereby reducing jamming and reducing the structural complexity of the compensation structure 13.

[0078] Optionally, the swing structure 12 is arranged in an L shape.

[0079] In some embodiments, the swing bar 121 and the sliding bar 122 are integrally formed.

[0080] In some embodiments, the swing rod 121 and the sliding rod 122 are formed separately, and the swing rod 121 and the sliding rod 122 are fixedly connected via a fixing member or the like.

[0081] In some embodiments of the present invention, see Figure 2 and Figure 3 The sliding rod 122 is provided with a sliding groove 1221 for the compensation structure 13 to pass through, and the sliding groove 1221 penetrates both sides of the sliding rod 122 along the sliding direction of the swing structure 12. In this way, both ends of the sliding compensation part 131 of the compensation structure 13 can extend out of the sliding groove 1221 and connect with the arc-shaped part 1322 of the compensation structure 13, so that the swing structure 12 can be limited to prevent the swing structure 12 and the compensation structure 13 from falling off from each other.

[0082] In some embodiments, the number of arc-shaped portions 1322 of the compensation structure 13 is multiple, and accordingly, the number of sliding compensation portions 131 and the number of sliding grooves 1221 are the same as the number of arc-shaped portions 1322, and the two sliding grooves 1221 are sequentially arranged at intervals along the rotation center axis direction of the swing structure 12. In this way, the relative sliding of the sliding rod 122 and the compensation structure 13 can be made more stable, and the sliding rod 122 will not tilt relative to the rotation center axis of the swing structure 12.

[0083] Optionally, the number of the sliding compensation portions 131 , the number of the sliding grooves 1221 , and the number of the arc-shaped portions 1322 are all two, three, or the like.

[0084] In some embodiments of the present invention, when the bending jig 20 is fixed to the bending jig driving device, the first rotating plate 21 can be fixed to the first fixed structure 151 by screws, and the first rotating plate 21 can be fixed to the first fixed structure 151 by suction cups.

[0085] In some embodiments of the present invention, when the bending jig 20 is fixed to the bending jig driving device, the second rotating plate 22 can be fixed to the second fixed structure 152 by screws, and the second rotating plate 22 can be fixed to the second fixed structure 152 by suction cups.

[0086] In some embodiments of the present invention, see Figures 1 to 6 The bending jig driving device also includes a workbench 144, a first fixing frame 141 and a second fixing frame 142. The bottoms of the first fixing frame 141 and the second fixing frame 142 are both fixed on the workbench 144, the top of the first fixing frame 141 can be a first fixing structure 151, and the driving member 11 is fixed on the second fixing frame 142.

[0087] The specific structures of the first fixing frame 141 and the second fixing frame 142 are not limited here.

[0088] In some embodiments of the present invention, see Figure 2 and Figure 6 The second fixing structure 152 is a plate-shaped structure and can be a fixing plate.

[0089] See also Figures 1 to 6 The present invention also provides a bending jig system, which includes a bending jig 20, a camera 30, and a bending jig driving device in any of the above embodiments, wherein the bending jig driving device is used to drive the first rotating plate 21 and the second rotating plate 22 of the bending jig 20 to rotate relative to each other, and the camera 30 is used to shoot the side of the bending part of the bending jig 20. When the folding module is placed on the bending jig 20 and the bending jig 20 is installed on the bending jig driving device, the bending jig driving device works, and the second rotating plate 22 of the bending jig 20 can rotate relative to the first rotating plate 21. Accordingly, the folding module folds, and the camera 30 can record the shape of the bending part of the bending jig 20 (the connection part of the first rotating plate 21 and the second rotating plate 22) and the folding part of the folding module, as well as the displacement of each layer of the folding module.

[0090] The bending jig system provided by the present invention adopts the above-mentioned bending jig driving device, which includes a first fixed structure 151, a second fixed structure 152, a driving member 11, a swinging structure 12 and a compensation structure 13. The first fixed structure 151 and the second fixed structure 152 are respectively used to be fixed on the first rotating plate 21 and the second rotating plate 22 of the bending jig 20. The driving member 11 is used to drive the swinging structure 12 to swing. The swinging of the swinging structure 12 can drive the second rotating plate 22 to rotate relative to the first rotating plate 21, thereby achieving bending of the bending jig 20. Moreover, the swinging structure 12 is slidably connected to the compensation structure 13, and the compensation structure 13 is rotatably connected to the second fixed structure 152. Therefore, when the swinging structure 12 rotates, the swinging structure 12 can slide relative to the compensation structure 13, and the compensation structure 13 can rotate relative to the second fixed structure 152, which can reduce the jamming of the bending jig driving device during use to avoid damaging the bending jig 20.

[0091] In some embodiments of the present invention, the bending jig system further includes a third fixing frame 143 , which is fixed on the workbench 144 , and the shooting camera 30 can be fixed on the third fixing frame 143 .

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
