This application is capable of embodiment in many different forms than those described herein and those skilled in the art will be able to make similar modifications without departing from the spirit of the application and therefore the application is not limited to the specific embodiments disclosed below.

Furthermore, the figures are not 1:1, and the relative dimensions of the various elements in the figures are drawn for illustration only and not necessarily to true scale.

In order to facilitate understanding of the technical solution of the present invention, before the detailed description, an adjusting device in the related art will be described first.

When winding the target, for example, during the process of winding the silicone tape, it is often necessary to keep the silicone tape in a tensioned state all the time. For example, the silicone tape may be used for a touch display device. However, during the winding action, it is often difficult to maintain the tension of the target piece by relying solely on the winding mechanism in the winding apparatus. On the basis, the inventor tries to add an adjusting device to adjust the winding angle, namely, the winding mechanism is reversely rotated by the adjusting device, so that the target part is prevented from loosening to a certain extent. It should be understood that the adjusting device of the present application is exemplified for winding a silicone strip, which is by way of illustration and not limitation.

Fig. 1 shows a schematic structural diagram of an adjusting apparatus 10 in an embodiment of the related art.

As shown in fig. 1, an adjusting apparatus 10 in an embodiment of the related art includes a driving member 11. In connection with some embodiments described later, the driving member 11 is used in connection with the winding mechanism 400 in the winding apparatus 1000 to provide a driving force for driving the first winding member 410 in the winding mechanism 400 to reverse. In this way, when the winding mechanism 400 winds the silicone tape, the first winding member 410 is driven to rotate reversely by the driving force of the driving member 11, so that the silicone tape is kept tensioned. Further, the adjustment device 10 also comprises a mounting 12. The mounting member 12 is adapted to be coupled between the driving member 11 and the frame 300 in the winding apparatus 1000. In this way, a stable mounting position for the driver 11 can be provided by means of the mounting 12. The drive member 11 is illustratively an electric motor.

However, the inventor has found that the driving member 11, such as a motor, often needs to be driven by a control unit to control the rotation angle, so that the entire device is complicated in structure. Meanwhile, the applicable scenes of the motor have more limitations and higher requirements. More importantly, the tension state of the silicone tape is not constant in the actual winding process. The motor is usually rotated to a preset angle under the control of the control unit, that is, the rotation angle of the driving member 11 such as the motor cannot be adaptively adjusted, and cannot be adaptively positioned at the angle when the driving member is rotated to a proper position. Therefore, it is difficult for the motor to adaptively adjust the rotation angle according to the real-time winding state of the silicone tape, and it is also difficult to ensure that the silicone tape is always kept tensioned.

In addition, the inventor of the present application has also noticed that the torque provided by the motor is constant, and when winding different silicone tapes, the load is not constant, so the torque required to keep the silicone tapes tensioned is not constant. If the torque value of the motor is adjusted, a speed reducer and other devices need to be added, so that the structural complexity of the whole device is further increased, and the control requirement on the control unit is higher.

Based on this, the inventor of the present application has conducted extensive studies, and by improving the structure of the adjusting device 10, instead of the driving member 11 such as a motor, the rotation angle can be adaptively adjusted by a simple structure, so that the silicone belt can be kept in a tensioned state to the maximum extent.

For the purpose of illustration, the drawings show only the structures associated with the embodiments of the application.

Fig. 2 shows a schematic structural diagram of the adjusting device 100 in an embodiment of the present application; fig. 3 shows an exploded view of the adjustment device 100 in an embodiment of the present application.

Referring to fig. 2 and 3, an adjusting apparatus 100 according to an embodiment of the present disclosure includes a connecting shaft 110, a fixing member 120, an abutting member 130, and a plurality of elastic members 140. The fixing member 120 is sleeved outside the connecting shaft 110, and an installation space is defined between an inner surface of the fixing member 120 and an outer circumferential surface of the connecting shaft 110. The abutting piece 130 is arranged in the installation space Z ₁ In this case, the abutting member 130 includes a plurality of abutting portions 131, and all of the abutting portions 131 sequentially surround the connecting shaft 110 in the axial direction of the connecting shaft 110. The adjacent abutting portions 131 are elastically connected to each other by at least one elastic member 140. Wherein, the elastic member 140 is configured to provide a preset elastic force for forcing the abutting portion 131 to abut against the fixing member 120, and all the abutting portions 131 can enclose to form a limiting space Z for limiting the connecting shaft 110 ₂ 。

It should be noted that, adjacent abutting portions 131 are elastically connected by at least one elastic member 140, that is, as long as the elastic member 140 can provide a predetermined elastic force for keeping the abutting portions 131 against the fixing member 120, the elastic member can be reversed by the predetermined elastic force when receiving the winding acting force.

With reference to some embodiments described later, when the connecting shaft 110 receives the winding acting force from the winding apparatus 1000 to drive the abutting member 130 to rotate forward, the preset elastic force provided by the elastic member 140 forces the abutting member 130 to abut against the fixing member 120, and the preset elastic force can drive the abutting member 130 to rotate backward, so as to drive the connecting shaft 110 to rotate backward relative to the fixing member 120, that is, the rotation angle between the connecting shaft 110 and the fixing member 120 is adaptively adjusted by the preset elastic force. The adjusting device 100 in the present application can keep the target 200, i.e., the silicone tape, in the winding apparatus 1000 in tension at all times by means of a simple structure.

Fig. 4 shows a force analysis diagram of the adjusting apparatus 100 in an embodiment of the present application.

Referring to fig. 4 in conjunction with fig. 2 and 3, in some embodiments, the inner surface of the stationary member 120 is configured to have an axis of rotation/ ₁ Of the inner cylindrical surface of (a). The preset elastic force has a first component force F in a tangential direction of the inner surface of the fixing member 120 _α First component of force F _α The connecting shaft 110 can be driven to rotate relative to the fixing member 120 when the connecting shaft 110 is subjected to an external force. Axis of rotation l ₁ To the central axis l of the connecting shaft 110 ₂ Coincide with each other.

As can be seen from the force analysis diagram shown in FIG. 4, the predetermined elastic force F of the elastic member 140 ₁ Satisfies the formula F ₁ K × Δ x, where K is the elastic modulus and Δ x is the amount of elastic deformation. According to the stress analysis of the preset elastic force, the first component force F of the preset elastic force in the tangential direction is known _α Is calculated by the formula F _α ＝F ₁ X sin θ. It can be understood that the preset elastic force forces the abutting member 130 to abut against the fixing member 120, and the second component force F of the preset elastic force in the normal direction is known by combining the force analysis of the preset elastic force _β Satisfies the calculation formula F _β ＝F ₁ X cos θ. During the rotation of the abutting member 130 relative to the fixing member 120, the outer peripheral surface of the abutting member 130 rubs against the inner surface of the fixing member 120 to generate a friction force f, which prevents the abutting member 130 and the fixing member 120 from continuing to rotate. As can be seen from the calculation formula of the frictional force, the frictional force F satisfies F = μ × F _β Wherein μ is a friction coefficient. According to the torque calculation formula, the torque T is equal to the product of the force and the moment arm, and the force for driving the abutting member 130 to reverse relative to the fixing member 120 is the first component force F in the tangential direction _α And the friction force F, while the inner surface of the fixing member 120 is configured as an inner cylindrical surface, i.e., it is a circular cross section having a center O, the moment arm is the radius R in the inner surface of the fixing member 120, i.e., the torque T satisfies the formula T = (F) _α + f). Times.R. Based on the above analysis, the formula T = K × Δ x × R (sin θ + μ cos θ) can be derived.

It will be understood that the torque T of the adjustment device 100 is only related to the elastic coefficient K of the elastic member 140, the amount of elastic deformation Δ x, the radius R of the inner surface of the fixing member 120, and the coefficient of friction μ between the fixing member 120 and the abutment member 130. In combination with some embodiments described later, when the adjusting device 100 needs to maintain a stable torque T, the torque T of the adjusting device 100 does not change due to the change of the winding force and the relative rotation speed between the fixing member 120 and the connecting shaft 110.

When the torque T needs to be adjusted, the elastic member 140, the fixing member 120 or the abutting member 130 can be selectively adjusted or replaced. The elastic member 140 may be a spring, for example, and when the amount Δ x of elastic deformation of the spring is adjusted, the amount Δ x of elastic deformation may be increased or decreased as needed by changing parameters such as a wire diameter of the spring and a length of the spring. The friction coefficient μ between the fixing member 120 and the abutting member 130 can be changed by replacing the fixing member 120 or the abutting member 130 with different materials. It should be noted that, because the friction force f exists between the abutting member 130 and the fixing member 120, after a long time of operation, abrasion may occur between the abutting member 130 and the fixing member 120, and the abutting member 130 or the fixing member 120 may be selectively replaced. Moreover, the material of the adjustment device 100 is not limited, and the applicability of the adjustment device 100 is also made stronger. For example, in an environment of strong electricity, strong magnetism, etc., the adjustment device 100 can still operate normally and stably without interference by selecting a suitable material. In addition, the size of the elastic member 140, the fixing member 120 or the abutting member 130 may be adjusted to adjust the torque T of the adjusting device 100, and in addition, since the size of the adjusting device 100 is not limited by the size of any electric component, such as a motor in the related art, the adjusting device 100 is not limited by space, and the adjusting device 100 can provide a stable moment load even in a narrow space.

Referring again to fig. 2 and 3, in some embodiments, the number of the abutting portions 131 includes two. The two abutting portions 131 are oppositely arranged along the radial direction of the fixing member 120, and the opposite connecting ends of the two abutting portions 131 are elastically connected with each other by means of at least one elastic member 140. Thus, two radial phasesThe arrangement of the abutting portions 131 can simplify the structure of the adjusting device 100, and the elastic member 140 exerts a predetermined elastic force, the second component force F of which is applied to the two abutting portions 131 _β The abutting portion 131 can be more reliably urged against the fixing member 120, and the frictional force f between the abutting portion 131 and the fixing member 120 can be increased. Further, a space is formed between the opposite connection ends of the two abutting portions 131. In this manner, the ease of assembly of the adjustment device 100 is improved by the spacing between the connection ends. During the assembly process, the two abutting portions 131 can be brought close to each other by the gap when an external force is applied, so that the installation space Z between the fixing member 120 and the connecting shaft 110 can be more easily entered ₁ And (4) the following steps. After the external force is removed, the preset elastic force provided by the elastic member 140 between the two abutting portions 131 can force the abutting portions 131 against the fixing member 120, thereby completing the assembly of the adjusting device 100.

Referring to fig. 2 and 3, in some embodiments, all of the elastic members 140 are symmetrically disposed about a radial reference plane of the connection shaft 110. Wherein the radial reference plane passes through the central axis l of the connecting shaft 110 ₂ . Thus, all the elastic members 140 symmetrically arranged can provide more uniform and stable preset elastic force between the two abutting portions 131, so as to avoid the problems of inclination and the like caused by uneven stress between the two abutting portions 131, and thus the adjusting device 100 fails. Specifically, the elastic member 140 includes two. Thus, the two elastic members 140 can provide reliable predetermined elastic force for the abutting portion 131, which not only simplifies the structure, but also reduces the cost.

It is understood that each two abutting portions 131 are elastically connected to each other by two elastic members 140. With reference to some embodiments described later and fig. 3, when the abutting parts 130 include two abutting parts, correspondingly, there are four abutting parts 131 in the adjusting device 100, and there are four elastic parts 140 connected between the abutting parts 131. Further, the opposite connection ends of each abutting portion 131 are provided with mounting grooves 1312, and the interval between the bottom walls of the two opposite mounting grooves 1312 is smaller than the axial dimension of the elastic member 140. In this way, it is possible to more easily install the elastic member 140 by means of the two opposite installation grooves 1312, and to limit the amount of elastic deformation Δ x of the elastic member 140 by means of the interval of the bottom wall between the two installation grooves 1312.

With continued reference to fig. 3, in some embodiments, a groove 1311 is formed on a side of each abutting portion 131 facing the connecting shaft 110. All the grooves 1311 are jointly configured to form a limiting space Z ₂ . As such, the connecting shaft 110 can be accommodated more easily by means of the entire groove 1311. In some embodiments, the connection shaft 110 has a fitting portion 1111 at least partially on an outer circumferential surface thereof. The engagement portion 1111 at least partially engages with the bottom wall of the groove 1311 to restrict relative rotation between the connection shaft 110 and all of the abutments 131. Thus, when the predetermined elastic force drives the abutting member 130 to rotate relative to the fixing member 120, the abutting member 130 can reliably drive the connecting shaft 110 to rotate together, so as to avoid the phenomenon that the abutting member 130 rotates and the connecting shaft 110 does not rotate. Of course, in other embodiments, the relative movement of the abutment member 130 and the connecting shaft 110 can be avoided only by the friction force therebetween, which is not limited herein.

Referring to fig. 4 again, in conjunction with fig. 3, an orthogonal projection of the groove 1311 on a plane perpendicular to the axial direction of the connecting shaft 110 is further defined as a first projection P. The outer contours of all the first projections P enclose a rectangle. It can be understood that opposite sides of the rectangle are parallel to each other, and the fitting portion 1111 on the outer circumferential surface of the connecting shaft 110 is fitted with the bottom wall of the groove 1311, that is, the fitting portion 1111 is at least partially configured in a plane structure, so that the relative rotation between the abutment member 130 and the connecting shaft 110 is more easily restricted by the fit of the plane structure with the bottom wall. Specifically, the outer circumferential surface of the connecting shaft 110 has two engagement portions 1111, and the two engagement portions 1111 are disposed opposite to each other in the radial direction of the connecting shaft 110. As such, the two mating portions 1111 can restrict the relative rotation of the abutment 130 and the connecting shaft 110 from two positions, so that the restriction is more reliable.

As shown in fig. 2 and 3, in some embodiments, the two abutting members 130 are provided at the installation space Z along the axial direction of the connecting shaft 110, and the two abutting members 130 are spaced from each other ₁ And (4) the following steps. Thus, the two contact members 130 can increase the contact area between the contact members 130 and the fixing member 120, thereby avoiding the contactThe friction is not too low and it is also possible to avoid insufficient stability of the adjustment device 100 and even the occurrence of the abutment 130 from the installation space Z ₁ The problem of internal separation.

Referring to fig. 3, in some embodiments, the connecting shaft 110 has a shaft body 111 and a positioning portion 112 disposed on the shaft body 111, and each abutting member 130 is at least partially positioned on the positioning portion 112. In this way, the abutment 130 can be reliably positioned by the positioning portion 112, and the ease of assembling the adjustment device 100 can be improved. In other embodiments, the inner surface of the fixing member 120 is provided with a step portion 121, and each abutting member 130 is at least partially positioned at the step portion 121. In this way, the step portion 121 can provide a positioning position for the abutment 130, and the assembly of the adjustment device 100 can be easily performed. In the embodiment of the present application, the connecting shaft 110 has a shaft body 111 and a positioning portion 112 provided on the shaft body 111, and the inner surface of the stator 120 is provided with a step portion 121. In this way, the positioning portion 112 and the step portion 121 cooperate to position the abutting piece 130, so that the positioning area of the abutting piece 130 can be increased, and the positioning in the axial direction is more stable. Moreover, with the aid of the stepped portion 121, the size of the positioning portion 112 can be reduced accordingly, so as to avoid increasing the difficulty of assembly due to friction or interference with the positioning portion 112 when the fixing element 120 is sleeved on the connecting shaft 110.

With continued reference to FIG. 3, in some embodiments, the shaft body 111 includes a first shaft segment A and a second shaft segment B connected to each other. The positioning portion 112 is disposed on the second shaft section B, and at least a portion of the first shaft section a is provided with a threaded portion. In connection with some embodiments described later, the winding mechanism 400 can be more easily connected by means of the threaded portion on the first shaft section a. Furthermore, a clamping groove B is formed in the second shaft section B and used for installing a fastener to axially limit the abutting piece 130. Furthermore, the two ends of the second shaft section B are both provided with the clamping grooves B, and in combination with the foregoing embodiments, the clamping grooves B at the two ends can easily install a fastener at the two ends of the second shaft section B, so that the two abutting pieces 130 can be both reliably limited, and the abutting pieces 130 and the fixing piece 120 are prevented from being separated from each other in the working process of the adjusting device 100. Illustratively, the fastener may be a snap spring, and the snap groove b is a snap spring groove.

Fig. 5 shows a schematic view of a winding apparatus 1000 in an embodiment of the present application.

Referring to fig. 5 in combination with fig. 2 to 4, based on the same inventive concept, another aspect of the present application further provides a winding apparatus 1000 for winding the target object 200, where the target object 200 may be, for example, a silicone tape, and the silicone tape may be applied to a touch display module. The winding plant 1000 comprises the above-described adjusting device 100. The winding apparatus 1000 using the above-described adjusting device 100 can keep the silicone tape in a tensioned state all the time by means of the adjusting device 100 providing a stable torque.

As shown in fig. 2-5, in some embodiments, the winding apparatus 1000 includes a magazine 300 and a winding mechanism 400. The fixing member 120 is connected to the frame body 300, the connecting shaft 110 is connected to the winding mechanism 400, and the winding mechanism 400 drives the connecting shaft 110 to rotate so that the acting force of winding the silicone tape is the winding acting force. At least part of the predetermined elastic force is capable of counteracting the winding force. Thus, at least part of the preset elastic force is offset with the winding acting force, so that the abutting part 130 can drive the connecting shaft 110 to rotate reversely, the rotating angle of the connecting shaft 110 relative to the fixing part 120 is adjusted in a self-adaptive manner, and the silica gel belt can be always kept tensioned. In some embodiments, the fixing member 120 is fixed to the frame 300 by means of a connector. Illustratively, the connector may be a bolt assembly. Further, one end of the fixing member 120 is opened with a plurality of connecting holes 122, and the plurality of connecting holes 122 are arranged at intervals along the circumferential direction. As such, it is easier to connect the connector to the fixing member 120 through the frame body 300 by means of the plurality of connection holes 122. In the embodiment shown in fig. 2, 3 and 4, the number of the connection holes 122 is four.

With continued reference to fig. 5 in conjunction with fig. 2 and 3, in some embodiments, the winding mechanism 400 includes a first winding member 410 and a second winding member 420, and the first winding member 410 is connected to the connecting shaft 110. The silicone tape is wound between the first winding member 410 and the second winding member 420. In this way, a working position can be provided for the silicone strip by means of the first winding member 410 and the second winding member 420. Specifically, the first winding member 410 is connected to the connecting shaft 110, and the second winding member 420 is connected to the frame body 300. Thus, when the silica gel tape is wound, the first winding member 410 is driven to rotate by the motion of the silica gel tape, that is, the connecting shaft 110 is driven to rotate, so that the adjusting device 100 can operate to keep the silica gel tape tensioned.

As shown in fig. 2 to 4, in the adjusting device 100 and the winding mechanism 400 provided in the embodiment of the present application, the adjusting device 100 at least includes a connecting shaft 110, a fixing member 120, an abutting member 130, and a plurality of elastic members 140. When the connecting shaft 110 is subjected to the winding action force in the winding device 1000 to drive the abutting part 130 to rotate forward, the abutting part 130 is forced to abut against the fixing part 120 by the preset elastic force provided by the elastic part 140, and the preset elastic force can drive the abutting part 130 to rotate backward, so that the connecting shaft 110 is driven to rotate backward relative to the fixing part 120, that is, the adjusting device 100 with a simple structure in the present application can adaptively adjust the rotation angle between the connecting shaft 110 and the fixing part 120 by means of the preset elastic force, so that the silicone belt in the winding device 1000 can be always kept tensioned. According to the force analysis, the torque T of the adjusting device 100 is only related to the characteristics of the components in the adjusting device 100, such as the elastic member 140, the fixing member 120, and the abutting member 130, and is not affected by the winding force and the rotation speed to change the torque T, which ensures the stability of the torque T. The two abutting portions 131 are oppositely arranged along the radial direction of the fixing member 120, and a space is formed between the opposite connecting ends of the two abutting portions 131, so that the assembling easiness of the adjusting device 100 is improved. The groove 1311 of the abutting portion 131 is engaged with the engaging portion 1111 of the connecting shaft 110, so that the abutting member 130 can reliably drive the connecting shaft 110 to rotate along with the groove, thereby preventing the abutting member 130 from rotating and the connecting shaft 110 from not rotating. The arrangement of the two abutting members 130 on the connecting shaft 110 can increase the contact area between the abutting members 130 and the fixing member 120, thereby avoiding the friction force from being too small, and also avoiding the stability of the adjusting device 100 from being insufficient, even the abutting members 130 from the installation space Z ₁ The problem of internal separation. By means of the positioning portion 112 on the connecting shaft 110 and the step portion 121 on the inner surface of the fixing member 120, the abutting member 130 can be positioned cooperatively, and the abutting can be increasedThe positioning area of the member 130, thereby making the positioning in the axial direction more stable. The winding device 1000 using the adjusting device 100 provided by the application can keep the silica gel tape in a tensioned state all the time by means of the adjusting device 100 providing stable torque.
