Technical Field

The application relates to the technical field of bending tests, in particular to a bending device, a bending test system and a bending method.

Background

At this stage, folded screens have become increasingly popular, which are made of flexible display materials, including flexible glass. Flexible glass can store stress at the processing site during production and processing, causing some imperceptible damage, or microcracks, edge chipping, etc. If the defective glass having defects and flaws flows to a downstream process and is applied to terminal equipment for assembly, the terminal equipment is prone to malfunction, and the use is affected.

The application provides a bending device. Referring to fig. 1 to 7, the bending apparatus 100 includes a first supporting element 110, a first bending element 120, and a tension mechanism (not shown). Referring to fig. 1, a pulling mechanism is used to pull the material forward, in this embodiment, the material is flexible glass 101, and in other embodiments, the material may be of other types, and is not limited herein. Referring to fig. 1, the upper and lower surfaces of the flexible glass 101 are covered with protective films 102 to prevent the flexible glass 101 from directly contacting other components and damaging the glass. The tension mechanism pulls the flexible glass 101 forward by pulling the protective film 102, instead of directly pulling the flexible glass 101, which can protect the glass from damage. For convenience of description, the front-back direction, the left-right direction, and the up-down direction as shown in fig. 1 are defined, the front-back direction is the pulling direction of the flexible glass 101, and the front-back direction, the left-right direction, and the up-down direction correspond to the first direction, the second direction, and the third direction in the following description, respectively.

The first support assembly 110 is used to support the flexible glass 101, and the first bending assembly 120 is disposed opposite the first support assembly 110. The first bending assembly 120 comprises a driving part and a bending part, and the driving part can drive the bending part to move up and down to bend the flexible glass 101. As shown in fig. 6, the first supporting member 110 is provided with a first accommodating space a, and the first bending member 120 can press the flexible glass 101 on the first supporting member 110 downward when moving toward the first supporting member 110, so as to press the flexible glass 101 into the first accommodating space a, thereby bending the flexible glass 101. The tensile mechanism is arranged on the front sides of the first supporting component 110 and the first bending component 120, the flexible glass 101 can be pulled to move forwards, the first bending component 120 presses down and bends the flexible glass 101, meanwhile, the flexible glass 101 is pulled forwards by the tensile mechanism, and in the process that the flexible glass 101 is pulled forwards, each part on the flexible glass 101 can be bent through the first bending component 120, so that dynamic bending is realized. The dynamic bending mode can enlarge the defects at each position on the flexible glass 101, is easy to observe or detect, and avoids the materials with the defects from flowing into the downstream process.

It is understood that the bending apparatus 100 of the present application can be applied not only to bending of flexible glass 101, but also to bending of other sheet materials, strip materials, and especially flexible sheet materials.

In order to bend the flexible glass 101 in different directions, as shown in fig. 1 to 7, the bending apparatus 100 further includes a second supporting assembly 130 and a second bending assembly 140. The second bending unit 140 is disposed at a distance from the first bending unit 120 in a pulling direction of the flexible glass 101, i.e., in a front-rear direction, that is, the first bending unit 120 and the second bending unit 140 are disposed at different positions in the pulling direction of the flexible glass 101. And the second bending assembly 140 is disposed at the opposite side of the first bending assembly 120, i.e., the first bending assembly 120 and the second bending assembly 140 are disposed one on the upper side of the flexible glass 101 and one on the lower side of the flexible glass 101. In the embodiment of the present application, as shown in fig. 1, the first bending assembly 120 is disposed at the upper side, and the first bending assembly 120 moves downward to bend the flexible glass 101; the second bending assembly 140 is disposed at the lower side, and the second bending assembly 140 moves upward to bend the flexible glass 101. The second bending assembly 140 also includes a driving member and a bending member, and the driving member can drive the bending member to move up and down to bend the flexible glass 101. The second bending assembly 140 is disposed opposite to the second supporting assembly 130, as shown in fig. 7, a second accommodating space b is disposed on the second supporting assembly 130, and the second bending assembly 140 can press the flexible glass 101 on the second supporting assembly 130 upwards and press the flexible glass 101 into the second accommodating space b, so that the flexible glass 101 is bent.

In the bending process, the tensile mechanism continuously pulls the flexible glass 101 forwards, and each position on the flexible glass 101 is bent by the first bending assembly 120 and the second bending assembly 140 respectively, so that each position on the flexible glass 101 is bent upwards and downwards, and defects on the flexible glass 101 are fully amplified and found.

In one embodiment, as shown in fig. 4 to 7, the first supporting element 110 and the second supporting element 130 are disposed opposite to each other, so that the first supporting element 110 and the second supporting element 130 can cooperate with each other to clamp the flexible glass 101, which is further advantageous for the bending element to bend the flexible glass 101. At least one of the first support assembly 110 and the second support assembly 130 is movable relative to the other so as to clamp or unclamp the flexible glass 101. As shown in fig. 4, in the initial state, the first support assembly 110 and the second support assembly 130 are away from each other, and are spaced apart from each other by a predetermined distance in the up-down direction; when a bending operation is required, as shown in fig. 5, the second support assembly 130 moves downward to clamp the flexible glass 101 together with the first support assembly 110; the flexible glass 101 is pulled forward by the tension mechanism, as shown in fig. 6, the first bending assembly 120 moves downward to bend the flexible glass 101 downward, and the flexible glass 101 is pulled forward while bending, so that each position on the flexible glass 101 is bent downward; as shown in fig. 7, the second bending assembly 140 moves upward to bend the flexible glass 101 upward, and pulls the flexible glass 101 forward while bending, so that the flexible glass 101 is bent upward everywhere.

When the first bending assembly 120 moves downwards to bend the flexible glass 101, the first support assembly 110 serves as a main support for bending the flexible glass 101, and meanwhile, the first support assembly 110 and the second support assembly 130 clamp the flexible glass 101 together to assist the flexible glass 101 in straightening. When the second bending assembly 140 moves upward to bend the flexible glass 101, the second supporting assembly 130 serves as a main supporting member for bending the flexible glass 101, and meanwhile, the first supporting assembly 110 and the second supporting assembly 130 clamp the flexible glass 101 together to assist the flexible glass 101 in straightening.

In one embodiment, as shown in fig. 2 and 8, each of the first bending element 120 and the second bending element 140 includes a rotation driving element 141, a bending shaft 142 and a bending driving element (not shown). The bending shaft 142 corresponds to the aforementioned bending member, and the bending driving member corresponds to the aforementioned driving member for driving the bending member to move up and down. The bending driving member may be any structure capable of achieving linear driving, such as a sliding table module, a linear motor, a cylinder, or a motor plus screw nut structure, and the like, without limitation. The rotary driving element 141 is used for driving the bending shaft 142 to rotate, so that the bending shaft 142 rotates when being pressed on the flexible glass 101, rolling friction rather than sliding friction is formed between the bending shaft 142 and the flexible glass 101, damage to the flexible glass 101 is avoided, and accordingly the lossless bending effect is achieved. The bending device 100 of the application can not damage the flexible glass 101 which meets the technical requirements of the process, but can make the defects of the flexible glass 101 which does not meet the technical requirements of the process more obvious. The bending shaft 142 is connected to an output end of the rotary driving member 141. In the embodiment of the present application, the rotary driving member 141 is a motor, and the motor drives the bending shaft 142 to rotate. The main body of the rotary drive 141 (i.e., the main body of the motor) is connected to the output end of the bending drive, and the output end of the rotary drive 141 (i.e., the rotor of the motor) is connected to the bending shaft 142. The bending driver can drive the rotary driver 141 and the bending shaft 142 to move together in the vertical direction, so that the bending shaft 142 bends the flexible glass 101. During the bending, the rotary driving member 141 can drive the bending shaft 142 to rotate. It can be understood that the rotation direction of the bending shaft 142 coincides with the moving direction of the flexible glass 101, and the linear velocity of the rotation of the bending shaft 142 coincides with the moving velocity of the flexible glass 101.

In the application, the bending shaft 142 is used as a bending piece, after the bending shaft 142 bends the flexible glass 101, the flexible glass 101 is coated on the periphery of the part of the bending shaft 142, and the bending radius of the flexible glass 101 is equal to the outer diameter of the bending shaft 142. The outer diameter of the bending shaft 142 can be very small, for example, the radius is 0.5 mm, 1 mm, 1.25 mm, 1.5 mm and the like, and the small-radius bending test requirement is met. Meanwhile, the surface of the bending shaft 142 is an arc, so that the flexible glass 101 is not scratched after being attached to the flexible glass 101. The bending shaft 142 may be made of tungsten steel, for example, and has a hardness of approximately 80 to 110, preferably 91.5. If the radius of the bending axis 142 is not required to be small, the bending axis 142 may be made of other materials such as stainless steel. If the shaft made of stainless steel is small in weight, the cost is high.

Referring to fig. 8 and 9, the first bending assembly 120 and the second bending assembly 140 further include a bow plate 143, a tension sleeve 144, a ball bearing 145, a thrust bearing 146, a shaft tension block 147, and a tension screw 148. The bow plate 143 is used as a mounting bracket of the bending component, and both ends of the bending shaft 142 are rotatably connected with the bow plate 143. The bow plate 143 is bow-shaped, and the middle is arched to provide a space for the bending shaft 142, so that the bending shaft 142 can bend the flexible glass 101. The rotary driver 141 is mounted at one end of the bow shape by a mounting seat 131. As shown in fig. 9, the tension bushing 144 is fitted over the bending shaft 142, the ball bearing 145 is provided between the tension bushing 144 and the bow plate 143, the thrust bearing 146 is also provided between the tension bushing 144 and the bow plate 143, the thrust bearing 146 and the ball bearing 145 are sequentially provided in the axial direction of the bending shaft 142, and the thrust bearing 146 is provided outside the ball bearing 145. A shaft tensioning block 147 is provided at one end of the tensioning sleeve 144, it being understood that the shaft tensioning block 147 is sleeved over the bent shaft 142. The tension screw 148 is used to lock the shaft tension block 147. The shaft tensioning block 147 and the tensioning sleeve 144 are tensioning components commonly used in the mechanical field, the shaft tensioning block 147 and the tensioning sleeve 144 are generally used in cooperation, and the structure and the installation manner of the shaft tensioning block 147 and the tensioning sleeve 144 are well known to those skilled in the art, and the structure and the installation method thereof will not be described in detail herein.

In this application, the bending shaft 142 is installed through the tensioning shaft sleeve 144, the ball bearing 145, the thrust bearing 146 and the shaft tensioning block 147, so that the bending shaft 142 can be always in a stretched state to ensure the bending effect.

Further, in order to provide a sufficient space for the bending shafts 142 of the first bending unit 120 and the second bending unit 140 to be installed and moved when the first support unit 110 and the second support unit 130 are disposed in a vertically opposite manner, as shown in fig. 5, a third accommodating space c is provided on the first support unit 110, and the bending shaft 142 of the second bending unit 140 is located in the third accommodating space c when the second bending unit 140 is not operated. As shown in fig. 5, the third accommodating space c and the second accommodating space b are opposite to each other in the up-down direction and communicate with each other. As shown in fig. 5, the bending axis 142 of the second bending assembly 140 is located in the third accommodating space c when the second bending assembly 140 is not in operation; when the second bending unit 140 operates, referring to fig. 5 and 7, the bending shaft 142 of the second bending unit 140 moves upward, the bending shaft 142 moves from the third accommodating space c to the second accommodating space b, and the flexible glass 101 is bent to the second accommodating space b.

Similarly, referring to fig. 5, a fourth accommodating space d is disposed on the second supporting assembly 130, and the fourth accommodating space d is opposite to the first accommodating space a in the vertical direction and is communicated with the first accommodating space a. As shown in fig. 5, when the first bending assembly 120 is not operated, the bending axis 142 of the first bending assembly 120 is located in the fourth accommodating space d; when the first bending unit 120 operates, referring to fig. 5 and 6, the bending shaft 142 of the first bending unit 120 moves downward, and the bending shaft 142 moves from the fourth accommodating space d to the first accommodating space a, so as to bend the flexible glass 101 into the first accommodating space a.

In one embodiment, as shown in fig. 2, the first support assembly 110 and the second support assembly 130 each include a mounting seat 131 and a rotating roller 132. The rotating roller 132 is rotatably connected to the mounting seat 131, so that when the flexible glass 101 moves on the rotating roller 132, the rotating roller 132 and the flexible glass 101 generate rolling friction, and the glass is prevented from being damaged. It is understood that the rotating roller 132 extends in the left-right direction with its axis of rotation parallel to the left-right direction. The rotating roller 132 may be a rubber roller to further protect the flexible glass 101.

Preferably, as shown in fig. 2, the rotating rollers 132 on the first supporting assembly 110 and the second supporting assembly 130 are multiple, the multiple rotating rollers 132 are arranged at intervals along the front-back direction, and gaps are formed between the rotating rollers 132, so that the gaps between the rotating rollers 132 can be used as the first accommodating space a, the second accommodating space b, the third accommodating space c and the fourth accommodating space d, and no accommodating space is required to be additionally arranged on the supporting assembly, which is beneficial to the design of the whole structure and simplifies the structure.

In one embodiment, at least one of the first support assembly 110 and the second support assembly 130 is connected to a clamping driving member, and the clamping driving member can drive the connected support assembly to move in an up-and-down direction so as to clamp the flexible glass 101. In the embodiment of the present application, the second support assembly 130 is connected to the clamping driving member, so that the second support assembly 130 can move closer to or away from the first support assembly 110, thereby achieving the effect of clamping the flexible glass 101.

The supporting component connected with the clamping driving component can be further provided with a buffer component, and the buffer component can enable the rotating roller 132 on the supporting component to have buffering during pressing, so that glass is prevented from being crushed. Since the second supporting assembly 130 is connected to the clamping driving member in the embodiment of the present application, a buffer member is disposed on the second supporting assembly 130, so that the second supporting assembly 130 has a buffer function during pressing. Referring to fig. 10, the second supporting assembly 130 includes a mounting seat 131, a rotating roller 132 and a buffer 133, and the mounting seat 131 includes a seat body 1311, a sliding sleeve 1312 and a sliding block 1313. The rotating roller 132 is rotatably connected to the sliding block 1313, the sliding block 1313 is slidably connected to the sliding sleeve 1312, the sliding block 1313 can move up and down in the sliding sleeve 1312, the buffer 133 is disposed between the sliding block 1313 and the sliding sleeve 1312, and the sliding sleeve 1312 is fixedly connected to the seat body 1311. When the second supporting assembly 130 moves downwards to press materials, after the rotating rollers 132 contact with the flexible glass 101, under the action of reaction, the rotating rollers 132 all have a tendency of moving upwards, the rotating rollers 132 push the sliding blocks 1313 to move upwards, and the sliding blocks 1313 push the buffering materials 133 to achieve buffering.

In one embodiment, as shown in fig. 10, the buffer 133 is a spring. The top end of the spring is connected to the sliding sleeve 1312 and the bottom end of the spring is connected to the sliding block 1313. The mounting seat 131 further includes a fixing screw 1314, and the fixing screw 1314 can fix the sliding sleeve 1312 on the seat body 1311 and can also limit the spring. As shown in fig. 10, the fixing screw 1314 passes through the seat body 1311 and the sliding sleeve 1312 sequentially from top to bottom and extends into the sliding sleeve 1312. Set screw 1314 fixes sliding sleeve 1312 to seat body 1311. Meanwhile, the top of the spring is sleeved on the fixing screw 1314, so that the fixing screw 1314 can be used for limiting the spring to prevent the spring from moving transversely, and a limiting structure is not additionally processed on the sliding sleeve 1312 to limit the spring.

The working process of the bending apparatus 100 in the embodiment of the present application is as follows:

The bending method can realize dynamic bending of the material, each part of the material is bent, the defects of the material can be enlarged, and the material is easy to observe or detect. The bending method can be realized by adopting the bending equipment.

In the bending method, the other supporting piece can be arranged on the supporting piece to compress the material, so that the material is convenient to bend. The other support can be driven to move up and down by external force.

In the bending method, the bending piece for bending the material adopts the bending shaft, and the bending shaft presses the material to realize bending. The bending shaft can have a smaller outer diameter, and small-radius bending is realized. The bending shaft rotates around the axis of the bending shaft when being pressed downwards, so that rolling friction rather than sliding friction is formed between the bending shaft and the materials, and the materials are protected from being damaged.

In the bending method, the material can be bent upwards and downwards through two different bending shafts. One bending shaft moves downwards to press the material, so that the material is bent downwards. And the other bend moves up to press the material axially, so that the material is bent upwards.

It should be understood that the above examples are merely examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. Numerous obvious variations, adaptations and substitutions will occur to those skilled in the art without departing from the scope of the present application. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
