The following description is presented to enable any person skilled in the art to make and use the present application. In the following description, for the purposes of explanation, details are set forth in order to provide a thorough understanding of the application. It should be apparent to those skilled in the art that the application can be practiced without the specific details presented below. In other instances, well-known structures and processes are not described in detail in order to avoid obscuring the application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.

[0027] In the production process of display devices such as televisions and displays, a traceless adhesive tape needs to be pasted on the frame of the display device, thereby covering the edge areas of the display surface, the peripheral side surface and the back surface of the display device, and protecting the display device and its frame across the three side surfaces. When the traceless adhesive tape is pasted, paste defects such as uneven pasting, pasting bubbles and warping often occur. At this time, the pasted traceless adhesive tape is usually smoothed by hand to make the traceless adhesive tape firmly adhere to the frame surface of the display device, thereby eliminating the paste defects and improving the paste quality. The operator needs to smooth the traceless adhesive tape on the display surface, the peripheral side surface and the back surface of the display device respectively, which results in a large labor burden and a long operation time, and the production efficiency is significantly reduced. Moreover, the hand is easily scratched when it contacts the traceless adhesive tape, and there is a risk of physical injury.

[0028] As shown in Figures 1 to 3 The embodiments of the present application provide a smoothing device 1, which includes a first smoothing body 10 and a second smoothing body 20, can efficiently and reliably smooth the traceless adhesive tape after it is pasted, thereby improving the smoothing efficiency and the paste quality of the traceless adhesive tape, and avoiding the risk of injury to the operator caused by the direct contact between the hand and the traceless adhesive tape.

[0029] The first smoothing body 10 has a first smoothing side 11 and a second smoothing side 12 arranged adjacent to each other, and the first smoothing side 11 and the second smoothing side 12 are perpendicular or inclined at an angle to match the positional relationship between the two adjacent side surfaces of the object to be smoothed 2, so that the first smoothing side 11 and the second smoothing side 12 can abut against the two adjacent side surfaces of the object to be smoothed 2 respectively. The second smoothing body 20 is movably retained on the first smoothing body 10, and a third smoothing side 21 is formed on the side of the second smoothing body 20 facing the first smoothing side 11; with the movement of the second smoothing body 20 relative to the first smoothing body 10, the first smoothing side 11 and the third smoothing side 21 can relatively approach to clamp the object to be smoothed 2, or relatively move away to release the object to be smoothed 2. Here, the object to be smoothed 2 can be determined according to actual needs, which can be a display device such as a television or a display, or other electronic devices that need to be smoothed, and the embodiments of the present application do not limit this.

[0030] When the first and second smearing bodies 10 and 20 are relatively clamped to the object 2 to be smeared, the edge portion of the object 2 to be smeared can be embedded in the area between the first smearing side 11, the second smearing side 12 and the third smearing side 21. The first smearing side 11 and the third smearing side 21 can be respectively abutted to the edge portion of the front and rear side surfaces of the object 2 to be smeared, and the first smearing side 11 and the third smearing side 21 can be respectively abutted to the edge portion of the front and rear side surfaces of the object 2 to be smeared. One of the first smearing side 11 and the third smearing side 21 can smear the traceless adhesive tape on the edge portion of the front side surface of the object 2 to be smeared, and the other one can smear the traceless adhesive tape on the edge portion of the rear side surface of the object 2 to be smeared. The second smearing side 12 can be abutted to the edge portion of the circumferential surface of the object 2 to be smeared to smear the traceless adhesive tape on the edge portion of the circumferential surface of the object 2 to be smeared. When the object 2 to be smeared is a display device such as a television or a display, the front side surface of the object 2 to be smeared can be the display surface of the display device, the rear side surface can be the back surface of the display device, and the circumferential surface can be the circumferential surface connecting the display surface and the back surface of the display device.

[0031] Here, the first smearing side 11, the second smearing side 12 and the third smearing side 21 can be enclosed to form a guide walking portion, so that the smearing device 1 can move along the extended edge of the object 2 to be smeared, such as the long side or the wide side, and sequentially pass through each area of the edge portion of the object 2 to be smeared, so that the first smearing side 11, the second smearing side 12 and the third smearing side 21 can sequentially smear the traceless adhesive tape on each area of the edge portion of the object 2 to be smeared. On the one hand, by using the arrangement structure of the first smearing side 11, the second smearing side 12 and the third smearing side 21, the smearing device 1 can simultaneously smear the traceless adhesive tape on the three side surfaces of the object 2 to be smeared, and has high smearing efficiency. On the other hand, by using the clamping force between the smearing device 1 and the object 2 to be smeared, the first smearing side 11, the second smearing side 12 and the third smearing side 21 can be respectively abutted to the object 2 to be smeared, thereby ensuring the smearing reliability and the smearing quality, and improving the smearing efficiency and the pasting quality of the traceless adhesive tape. In addition, the smearing operation process can avoid direct contact between the hand and the traceless adhesive tape, thereby eliminating the risk of injury to the operator.

[0032] In some embodiments, when the smoothing device 1 clamps the object 2 to be smoothed and performs the smoothing operation along an edge of the object 2 to be smoothed, at least one of the first smoothing side 11, the second smoothing side 12 and the third smoothing side 21 can be configured to be in line contact with the object 2 to be smoothed, and the contact line and the moving direction of the smoothing device 1 are perpendicular. Based on the line contact relationship, when the smoothing device 1 moves along the extended edge of the object 2 to be smoothed, such as the long side, the wide side or the like, the frictional damping between the smoothing device 1 and the object 2 to be smoothed can be reduced, thereby reducing the risk of surface damage that the object 2 to be smoothed may suffer due to the frictional damping, and increasing the smoothness and convenience of the moving operation of the smoothing device 1. Based on the perpendicular arrangement relationship between the contact line and the moving direction of the smoothing device 1, the contact line can be made to follow the edge of the object 2 to be smoothed to a larger area, thereby achieving a scanning smoothing operation with a higher coverage, and avoiding the problem of missing scanning of the traceless adhesive tape in the local area.

[0033] Here, several typical arrangement modes are briefly introduced. In some examples, only one of the first smoothing side 11, the second smoothing side 12 and the third smoothing side 21 is configured to be in line contact with the object 2 to be smoothed, and the contact line and the moving direction of the smoothing device 1 are perpendicular, and the other two smoothing sides are not arranged as above. In other examples, only two of the first smoothing side 11, the second smoothing side 12 and the third smoothing side 21 are configured to be in line contact with the object 2 to be smoothed, and the contact line and the moving direction of the smoothing device 1 are perpendicular, and the remaining one is not arranged as above. In yet other examples, the first smoothing side 11, the second smoothing side 12 and the third smoothing side 21 are respectively configured to be in line contact with the object 2 to be smoothed, and the contact line and the moving direction of the smoothing device 1 are perpendicular.

[0034] In some examples, the smoothing device 1 can include a smoothing roller 30, which can be arranged on at least one of the first smoothing side 11, the second smoothing side 12 and the third smoothing side 21. Here, the axial direction of the smoothing roller 30 can be perpendicular to the moving direction of the smoothing device 1, and the smoothing side where the smoothing roller 30 is arranged is in contact with the object 2 to be smoothed through the smoothing roller 30, so as to ensure the perpendicular arrangement relationship between the contact line and the moving direction of the smoothing device 1. In this way, when the first smoothing side 11, the second smoothing side 12 and the third smoothing side 21 can enclose to form the clamping through slot 14, the axial direction of the smoothing roller 30 can be perpendicular to the extension direction of the clamping through slot 14, i.e. the first direction. By arranging the smoothing roller 30, the line contact relationship between the side where the smoothing roller 30 is arranged and the object 2 to be smoothed can be more easily achieved, thereby achieving the corresponding effects as described above.

[0035] Here, several typical setting modes are briefly introduced. Exemplarily, only one of the first troweling side 11, the second troweling side 12 and the third troweling side 21 is provided with the troweling roller 30; further exemplarily, only one of the first troweling side 11, the second troweling side 12 and the third troweling side 21 is not provided with the troweling roller 30, and the other two troweling sides are respectively provided with the troweling roller 30; further exemplarily, the first troweling side 11, the second troweling side 12 and the third troweling side 21 are respectively provided with the troweling roller 30.

[0036] The number of the troweling rollers 30 located at the same side can be determined according to actual needs, and can be one or more, which is not limited in the embodiments of the present application. Exemplarily, when a plurality of troweling rollers 30 are provided on at least one of the first troweling side 11, the second troweling side 12 and the third troweling side 21, the plurality of troweling rollers 30 located at the same troweling side can be sequentially and spacedly arranged along the extension direction of the clamping through slot 14. Here, by providing a plurality of troweling rollers 30 on the same side as above, multiple line contact relationships can be formed between the troweling side where the plurality of troweling rollers 30 are located and the object to be troweled 2, so that the troweling side and the object to be troweled 2 have a stable and reliable abutting relationship, avoiding accidental shaking or unstable contact which affects the troweling effect, and the shaking of the first troweling body 10 and / or the second troweling body 20 which causes the knocking damage to the object to be troweled 2.

[0037] Exemplarily, the first troweling side 11 can be provided with a plurality of accommodating grooves 111. Each accommodating groove 111 is correspondingly provided with a troweling roller 30, and the troweling roller 30 is partially embedded in the accommodating groove 111. In this way, a simple and reliable mounting structure can be achieved.

[0038] In some examples, at least one of the first troweling side 11, the second troweling side 12 and the third troweling side 21 can have an arc surface structure. In this way, when the troweling device 1 clamps the object to be troweled 2 and moves along one side of the object to be troweled 2 to perform the troweling operation, the arc surface structure and the object to be troweled 2 are in line contact; here, the extension direction of the arc surface structure can be configured, for example, to extend along the moving direction of the troweling device 1, so that the contact line between the arc surface structure and the object to be troweled 2 is perpendicular to the moving direction of the troweling device 1. Further, when the first troweling side 11, the second troweling side 12 and the third troweling side 21 form the clamping through slot 14, the intersection line between the arc surface structure and the cross section of the clamping through slot 14 can be a straight line, which can ensure the perpendicular arrangement relationship between the aforementioned contact line and the moving direction of the troweling device 1. Exemplarily, the third troweling side 21 can have an arc surface structure; further, the second troweling body 20 can be a hyparc arch-shaped column body formed by extending a hyparc arch along the normal direction of its plane, and the third troweling side 21 can be formed on the arch back side of the hyparc arch-shaped column body.

[0039] For example, the top of the arc-shaped structure can be located in the middle region of the arc-shaped structure along the extension direction of the clamping through slot 14, and the cross-sectional area of the clamping through slot 14 can decrease from the opposite ends to the middle of the clamping through slot 14 along the extension direction of the clamping through slot 14. During the smoothing operation, the arc-shaped structure naturally contacts the object 2 to be smoothed through the top of the arc-shaped structure, and the contact line is located in the middle region of the arc-shaped structure, so that the stress condition during the operation process is relatively balanced, and the smoothing device 1 can maintain a relatively stable and reliable operation posture. By setting the cross-sectional area of the clamping through slot 14 as described above, the clamping through slot 14 can have a structure with large ends and a small middle along the extension direction, which can ensure reliable contact between the arc-shaped structure and the object 2 to be smoothed, and can avoid accidental contact between the two ends of the arc-shaped structure and the object 2 to be smoothed, which can cause structural damage to the latter.

[0040] In some examples, a plurality of smoothing rollers 30 can be provided on the first smoothing side 11 as described above, and the third smoothing side 21 can have an arc-shaped structure as described above, which can form a clamping structure that is relatively reliable in structure and easy to implement. In addition, the width of the arc-shaped structure is easy to adjust, and the width of the arc-shaped structure can be increased to match the smoothing operation requirements of a surface with a large size, or the width of the arc-shaped structure can be reduced to match the smoothing operation requirements of a surface with a small size, so that the smoothing device 1 has better versatility. For example, display devices usually have a relatively wide and flat display surface, and a smoothing roller 30 with a standard size is suitable for covering the edge of the display surface, so that the first smoothing side 11 can smooth the traceless tape on the edge. The edge plane of the back of some display devices is relatively narrow, even only a few millimeters, so the space available for the smoothing operation on the back of the display device is very limited. At this time, the third smoothing side 21 can be provided as an arc-shaped structure with a relatively narrow width, so that the third smoothing side 21 can be clamped to the edge plane of the back of the display device, thereby achieving accurate matching of the smoothing operation.

[0041] In some embodiments, the leveling device 1 can comprise an elastic connecting member 40. The elastic connecting member 40 is connected to the first leveling body 10 and the second leveling body 20 at two ends respectively, and is configured to relatively close the first leveling side 11 and the third leveling side 21 to clamp the object 2 to be leveled. Before clamping the leveling device 1 to the edge of the object 2 to be leveled, the elastic force of the elastic connecting member 40 can be overcome to drive the second leveling body 20 to move, relatively far apart the first leveling side 11 and the third leveling side 21 to provide sufficient embedding space, so that the edge of the object 2 to be leveled can be embedded in the area between the first leveling side 11, the second leveling side 12 and the third leveling side 21; after embedding, the driving force can be removed, and the elastic connecting member 40 can be reset to relatively close the first leveling side 11 and the third leveling side 21 to clamp the object 2 to be leveled. The type of the elastic connecting member 40 can be determined according to actual needs, and types such as springs, spring positioning pins, etc. can be used, which are not limited in the embodiments of the present application. In some examples, the leveling device 1 can comprise a guide column 70 arranged on the first leveling body 10, and the elastic connecting member 40 can be a spring, which is sleeved on the guide column 70.

[0042] In some examples, the second leveling side 12 is provided with a recessed portion 121 at one end away from the first leveling side 11, and the second leveling body 20 is partially arranged in the recessed portion 121. In this way, the side wall of the recessed portion 121 close to the first leveling side 11 blocks the local area between the first leveling side 11 and the second leveling body 20, so that the side wall can constrain the movement stroke of the second leveling body 20 to limit the relative closeness between the first leveling side 11 and the third leveling side 21, without affecting the relative clamping effect of the first leveling side 11 and the third leveling side 21. In other words, when the elastic connecting member 40 is reset to drive the second leveling body 20 to move, and then relatively close the first leveling side 11 and the third leveling side 21, the second leveling body 20 is limited by the limiting action of the side wall of the recessed portion 121 close to the first leveling side 11, and cannot further close to the first leveling side 11 by crossing the side wall, so that the second leveling body 20 can avoid overshoot, and the first leveling side 11 and the third leveling side 21 can avoid being too close to cause excessive clamping force, thereby ensuring the structural safety of the object 2 to be leveled when clamped.

[0043] The configuration of the recessed portion 121 can be determined according to actual needs, which is not limited in the embodiments of the present application. For example, the recessed portion 121 can be recessed integrally at one end of the second leveling side 12 away from the first leveling side 11, so that the recessed portion 121 has an open structure with only two side walls. For another example, the recessed portion 121 can be a groove portion, so that it has a semi-closed structure with at least three side walls.

[0044] Exemplarily, the second flattening body 20 can be an arc of a circle cylindrical body extended along the normal of the plane where it lies, and the third flattening side 21 can be formed on the arch side of the arc of a circle cylindrical body; here, the side wall of the recessed portion 121 close to the first flattening side 11 can have a concave structure matching the arch side, and the side wall of the recessed portion 121 away from the first flattening side 11 can have a planar structure.

[0045] Here, the driving mode of the second flattening body 20 can be determined according to actual needs, and can adopt modes such as electric driving, hydraulic / pneumatic driving, manual driving, etc., and the embodiments of the present application do not limit this. Exemplarily, the flattening device 1 can adopt a manual driving mode, and correspondingly include a manual driving control 50. The manual driving control 50 can be slidably arranged on the first flattening body 10 along the elastic extension direction of the elastic connecting member 40, one end of the manual driving control 50 extends into the recessed portion 121 and can act on the second flattening body 20, and the other end extends to the side surface of the first flattening body 10 away from the second flattening body 20. By accommodating the manual driving control 50 on the first flattening body 10, the space utilization and structural compactness can be improved.

[0046] In use, the operator can manually drive the manual driving control 50 from the side surface of the first flattening body 10 away from the second flattening body 20, so that the manual driving control 50 slides along the elastic extension direction of the elastic connecting member 40 to achieve the driving purpose of the second flattening body 20. For example, before clamping the flattening device 1 to the edge portion of the object 2 to be flattened, the operator can press the manual driving control 50 to drive the second flattening body 20 to move by sliding the manual driving control 50 along the elastic extension direction of the elastic connecting member 40 against the elastic force of the elastic connecting member 40, so that the first flattening side 11 and the third flattening side 21 are relatively far away to provide sufficient embedding space, so that the edge portion of the object 2 to be flattened can be embedded in the area between the first flattening side 11, the second flattening side 12 and the third flattening side 21.

[0047] The type of the manual driving control 50 can be determined according to actual needs, and can adopt types such as a pressing handle, a push-pull rod, etc., and the embodiments of the present application do not limit this. Figures 1 to 4 As shown in FIG. 6, exemplarily, the manual driving control 50 can include a pressing member 51 and at least one pressure head member 52 connected to each other, the pressing member 51 can be embedded on the side surface of the first flattening body 10 away from the second flattening body 20 for the operator to press, and the pressure head member 52 can be arranged on the first flattening body 10 and extend into the recessed portion 121 to act on the second flattening body 20 to achieve the transmission purpose.

[0048] For example, the manual driving control 50 can be arranged on the side of the second troweling body 20 away from the first troweling side 11, and the elastic connecting member 40 can be arranged on the side of the second troweling body 20 close to the second troweling side 12; or for example, the elastic connecting member 40 can be arranged on the side of the second troweling body 20 away from the first troweling side 11, and the manual driving control 50 can be arranged on the side of the second troweling body 20 close to the second troweling side 12. Through the above arrangement, the manual driving control 50 and the elastic connecting member 40 can be arranged on the two sides of the second troweling body 20, so as to form a compact layout structure and a driving transmission structure.

[0049] In some embodiments, the troweling device 1 can comprise a magnetic member 60 arranged on the first troweling body 10, which can be configured to be magnetically adsorbed to the object 2 to be troweled, so that the second troweling side 12 is tightly abutted to the object 2 to be troweled. Through the arrangement of the magnetic member 60, when the troweling device 1 is clamped to the edge of the object 2 to be troweled, the magnetic member 60 can be magnetically adsorbed to the object 2 to be troweled, and the second troweling side 12 is tightly abutted to the object 2 to be troweled by the magnetic attraction force between them, so as to ensure the close abutment of the second troweling side 12 to the object 2 to be troweled, and further ensure the troweling effect.

[0050] The troweling device provided by the embodiments of the present application is described in detail above, and the principles and implementation manners of the present application are described by applying specific examples. The above description of the embodiments is only used to help understand the method of the present application and its core idea; meanwhile, for those skilled in the art, the specific implementation manner and application range can be changed according to the idea of the present application, and the above description of the present application should not be understood as a limitation.
