Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

In the field of maintenance of intelligent terminal devices (smart phones, tablet computers and the like), screen disassembly and maintenance are common maintenance items. For example, when the terminal device falls and the screen is broken, the broken screen protection glass needs to be cut off by a screen cutter to be replaced with a new screen protection glass.

Currently, there may be cases where the surface height varies due to the screen being cut, for example, the screen is a curved screen, or the screen is bent due to a falling impact. This case may affect the cutting of the screen by the cutting part. For example, when the surface of the screen is raised upward, the cutting portion may be caught by the projection, resulting in failure of the cutting portion to continue its movement. Alternatively, when the surface of the screen is depressed downward, the cutting portion may cut the portion of the screen protection glass too shallow, or even hang in the air, so that the screen protection glass of the depressed portion is not cut.

Therefore, for solving above-mentioned problem, this application embodiment provides a cutting head, through the cutting portion that sets up suspensible, the radian up-and-down motion that the cutting portion can be directed against screen protection glass in the cutting process to guarantee that the cutting height of cutting portion laminates screen protection glass all the time.

For the purpose of understanding, specific implementations of embodiments of the present application are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to fig. 3, in which fig. 1 is a schematic view of a working scene of a cutting head according to an embodiment of the present disclosure; fig. 2 is a perspective view of a cutting head provided in an embodiment of the present application, and fig. 3 is a partially enlarged view of a portion a in fig. 2. As shown in fig. 2 and 3, a cutting head provided in an embodiment of the present application for cutting a panel of a terminal device includes: a body part 100, a cutting part 200, and a floating mechanism 300; the body part 100 is connected with the cutting part 200 through a floating mechanism 300, and the body part 100 is used for driving the cutting part 200 to move relative to the panel so as to cut the panel; wherein, the floating mechanism 300 comprises a guiding structure 310 and an elastic structure 320; the cutting part 200 is connected with the body part 100 in a floating way through the guide structure 310 and the elastic structure 320; the guide structure 310 serves to limit the moving direction of the cutting part 200 with respect to the body part 100; the elastic structure 320 has two ends respectively connected to the body part 100 and the cutting part 200.

In the present embodiment, optionally, as shown in fig. 1, the cut terminal device 10 is placed on the stage 20, and a guide rail 30 is provided below at least one of the body portion 100 or the stage 20 so that the body portion 100 and the stage 20 can slide relative to each other. The cutting part 200 is connected to the main body 100 through the floating mechanism 300, the main body 100 drives the cutting part 200 to move relative to the terminal device 10, and the trajectory of the relative movement is the cutting trajectory of the cutting part 200 for cutting the panel of the terminal device 10. Since the connection between the cutting part 200 and the body part 100 is a floating connection, the guide structure 310 limits the moving direction of the cutting part 200 to a direction close to or far from the terminal device 10, and the elastic structure 320 connects the body part 100 and the cutting part 200, respectively. During the cutting process, when the panel of the terminal device 10 is protruded, the cutting part 200 moves along the guide structure 310 in a direction away from the panel, and at this time, the elastic force provided by the elastic structure 320 maintains the downward pressure of the cutting part 200, so that the protruded panel is cut. When the panel of the terminal device 10 is depressed, the cutting portion 200 moves in a direction approaching the panel along the guide structure 310 by the tensile force of the elastic structure 320, thereby cutting the depressed portion of the panel. Therefore, through the cooperation of the guide structure 310 and the elastic structure 320, the suspended connection between the cutting part 200 and the body part 100 is realized, so that the cutting part 200 can adapt to the height change of the panel of the terminal device 10 during the cutting process.

Optionally, the panel may be a screen protection glass of a display screen of the terminal device, or the panel may also be a panel of a back case of the terminal device, for example, a glass back case of a smartphone, or a panel made of metal or plastic. Therefore, the terminal device panel cut by the cutting head according to the embodiment of the present application is not limited by the embodiment of the present application.

It should be noted that in the embodiment of the present application, there are various implementations of the guiding structure 310 and the elastic structure 320 of the floating mechanism 300, and for the convenience of understanding, the following detailed description is respectively combined with the drawings.

Optionally, the guiding structure 310 provided in the embodiment of the present application includes a guiding portion, the guiding portion is disposed on the main body portion 100, and the cutting portion 200 is slidably connected with the main body portion 100 through the guiding portion.

In this embodiment, the guide structure 310 includes a guide portion through which the cutting portion 200 is connected to the body portion 100, so that the cutting portion 200 can slide relative to the body portion 100, thereby limiting the direction in which the cutting portion 200 moves relative to the body portion 100.

It should be noted that the guide portion may be implemented in various ways in order to implement the sliding connection between the cutting portion 200 and the main body portion 100, for example, the guide portion may be configured as a guide groove opened on the main body portion 100, and the cutting portion 200 is connected with the guide groove so as to move in the guide groove relative to the main body portion 100. Optionally, the guide portion may also be provided as a sliding rail, so that the cutting head slides on the sliding rail. The present embodiment is not limited to this.

For convenience of understanding, the embodiment of the present application will be described in detail by taking the guide portion as a slide rail as an example.

Referring to fig. 4 and 5, fig. 4 is a side view of a cutting head according to an embodiment of the present disclosure, and fig. 5 is a partially enlarged view of a portion B in fig. 4. As shown in fig. 4 and 5, the guiding portion includes a first sliding rail 311, the first sliding rail 311 is connected to the body portion 100, and the cutting portion 200 is disposed on the first sliding rail 311 and can slide along the first sliding rail 311.

In this embodiment, the first sliding rail 311 is disposed on the body portion 100, and the first sliding rail 311 is perpendicular to the panel to be cut, so that the cutting portion 200 can approach or leave the panel when sliding along the first sliding rail 311.

It should be noted that, in order to limit the sliding range of the cutting part 200 on the first slide rail 311 and prevent the cutting part 200 from being separated from the first slide rail 311, the following scheme is further adopted in the embodiment of the present application.

Optionally, the guiding structure 310 further includes a limiting portion (not shown in the drawings), which is disposed on at least one end of the guiding portion to limit the sliding stroke of the cutting portion 200 relative to the body portion 100.

In this embodiment, when the guiding portion is configured as the first sliding rail 311, the limiting portion may be configured as a fixing block (not shown in the figure) fixed at an end of the first sliding rail 311, and when the cutting portion 200 slides to the fixing block, the cutting portion 200 cannot continue to slide along the current direction due to the limitation of the fixing block. Optionally, the fixing block may be disposed at one end of the first sliding rail 311, or disposed at two ends of the first sliding rail 311, which is not limited in this embodiment of the present application.

In the above description of the specific implementation manner of the guide structure 310 in the floating mechanism 300, in a specific operation, the guide structure 310 limits the moving direction of the cutting part 200 relative to the main body 100 to a direction close to or away from the panel, and on this basis, the elastic force provided by the elastic structure 320 drives the cutting part 200 to move along the guide structure 310 according to the unevenness of the panel. Thereby, the cutting part 200 is suspended on the body part 100 by the cooperation of the guide structure 310 and the elastic structure 320.

For ease of understanding, a detailed description of a specific implementation of the resilient structure 320 is provided below.

Optionally, the elastic structure 320 includes a first elastic member, and the elastic force provided by the first elastic member urges the cutting part 200 to be suspended on the body part 100.

In this embodiment, the cutting part 200 moves downward along the guide structure 310 due to gravity in an inactive state, and at this time, the elasticity of the first elastic member is required to maintain the cutting part 200 at the middle of the guide structure 310, thereby maintaining the levitation. When the cut panel is uneven during the operation of the cutting part 200, the cutting part 200 moves up and down along the guide structure 310 under the elastic action of the first elastic member, thereby realizing adaptive cutting.

It should be noted that, in order to maintain the elastic force required for suspension, the first elastic member may be implemented in various ways, including but not limited to: mode 1, the first elastic member is provided as a spring 321; mode 2, the first elastic member is provided as a spring cylinder; mode 3, the first elastic member is provided as a cylinder or a hydraulic cylinder; mode 4, the first elastic member is set to be magnetically levitated.

For the sake of understanding, the above-described embodiments will be described in detail below with reference to the accompanying drawings.

Mode 1, the first elastic member is provided as a spring 321.

In this embodiment, when the spring 321 is disposed below the cutting portion 200, the pushing force provided by the spring 321 keeps the cutting portion 200 suspended on the guiding structure 310 in the non-operating state, and when the cutting portion 200 encounters the panel protrusion and moves away from the panel during the cutting process, the spring 321 is stretched to provide a pulling force, so as to ensure the cutting pressure of the cutting portion 200 on the panel. When the spring 321 is disposed above the cutting portion 200, the pulling force provided by the spring 321 keeps the cutting portion 200 suspended on the guide structure 310 in an inoperative state, and during the cutting process, when the cutting portion 200 encounters the panel protrusion away from the panel, the spring 321 is compressed, and at this time, the spring 321 provides a pushing force to ensure the cutting pressure of the cutting portion 200 on the panel. Preferably, the upper and lower ends of the cutting part 200 are connected with the springs 321 at the same time, and the suspension of the cutting part 200 can be better realized by the cooperation of the two sets of springs 321.

Optionally, in addition to the cutting portion 200 being required to be suspended relative to the body portion 100 during the cutting process, in order to enable the cutting head provided in the embodiment of the present application to handle more terminal devices with different sizes, the cutting portion 200 is also required to be lifted and lowered relative to the body portion 100 adaptively to adapt to the height of the terminal devices. In contrast, the adjustment of the cutting portion 200 to the main body 100 is a coarse adjustment to ensure that the cutting portion 200 is aligned with the panel of the terminal device in the initial state, and the suspension of the cutting portion 200 to the main body 100 is a fine adjustment to ensure that the cutting portion 200 is adaptive to the height change of the panel during the operation.

For the convenience of understanding, the following provides a technical solution for simultaneously realizing the lifting adjustment and the suspension with reference to the attached drawings.

Alternatively, as shown in fig. 5, the first slide rail 311 of the guide structure 310 is disposed on the first mounting plate 110, the cutting part 200 is slidably connected to the first slide rail 311 through a slider 312, a connection point 312a is disposed on the slider 312, an upper end of the first sub-spring 321a is connected to an upper end of the first mounting plate 110, and a lower end of the first sub-spring 321a is connected to the connection point 312 a. The lower end of the second sub-spring 321b is connected to the lower end of the first mounting plate 110, and the upper end of the second sub-spring 321b is connected to the connection point 312 a.

And/or a second baffle is arranged at the lower end of the first mounting plate 110, the lower end of the second sub-spring 321b is connected with the second baffle, and the upper end of the second sub-spring 321b is connected with the cutting part 200. In this way, the position of the spring 321 is changed from being inclined to being upright, and the spring 321 can provide more elastic force during the compression or the relaxation.

It should be further noted that, for the above-mentioned lifting mechanism 400, it is mainly used to implement the function of adjusting the height of the first mounting plate 110, and for its specific implementation, the embodiment of the present application is not limited, and for easy understanding, the embodiment of the present application provides a preferred implementation.

Alternatively, as shown in fig. 4, the outer surface of the body part 100 is provided with a lift button 460, the lift button 460 is connected to the lift motor 410, and the lift button 460 is used for controlling the forward rotation or the reverse rotation of the lift motor 410, so as to control the lift block 430 to ascend or descend.

In this embodiment, through the cooperation of the lifting motor 410 and the first screw 420, when the first screw 420 rotates, the lifting block 430 is driven to move up and down, thereby driving the cutting part 200 to move up and down.

It should be noted that, in the process of lifting adjustment, when the cutting portion 200 is far away from the terminal device, the descending speed may be faster, so as to increase the adjustment efficiency, and when the cutting portion 200 is close to the terminal device, the descending speed should be slower, so as to avoid the damage caused by the too fast collision with the panel of the terminal device. In this regard, the embodiments of the present application provide the following solutions.

Referring to fig. 2, as shown in fig. 2, the lifting mechanism 400 further includes an adjusting member 440 and a display panel 450, wherein the adjusting member 440 and the display panel 450 are respectively exposed to an outer surface of the main body 100; the adjusting means 440 for adjusting the rotation speed of the elevating motor 410 to control the elevating speed of the floating part; the display panel 450 is used to display the adjustment value of the adjustment unit 440.

The first elastic members may be arranged in one group or two groups, which may be specifically referred to as the arrangement manner of manner 2, and will not be described herein again.

Optionally, a tank 326 is connected to the cylinder 323, and the pressure medium 325 stored in the tank 326 is conducted to the pressure medium 325 in the sealed space.

Alternatively, the amount of spring force provided can be varied by adjusting the pressure of the pressure medium 325 in the enclosed space, and/or by controlling the amount of area of the piston 324. This corresponds to the replacement of the spring 321 having a different spring constant in the embodiment 1.

In this embodiment, the elastic force required by the first elastic member is provided by the magnetic force between the magnets, and alternatively, the magnetic force between the first magnet 327 and the second magnet 328 may be an attractive force or a repulsive force, for example, when the first elastic member is disposed above the cutting part 200, the magnetic force between the first magnet 327 and the second magnet 328 is set as an attractive force in order to provide a pulling force, so that the second magnet 328 moves upward by the attraction of the first magnet 327.

While the above description describes a specific implementation manner of the cutting portion 200 to realize the floating connection on the body portion 100 in detail, the cutting portion 200 may have a plurality of implementation manners, and this is not limited by the embodiments of the present application, and for the convenience of understanding, a preferred implementation manner is provided below.

Referring to fig. 3, 10 and 11, fig. 10 is a schematic view of a limiting plate in a cutting head according to an embodiment of the disclosure; fig. 11 is a partial cross-sectional view of a stop plate and a blade in a cutting head according to an embodiment of the present disclosure. As shown in fig. 3, 10 and 11, the cutting part 200 provided in the embodiment of the present application includes a cutting motor 210, a blade 220 and a stopper plate 230, wherein; the blade 220 is disposed at an output shaft of the cutting motor 210; the limiting plate 230 is provided with an avoiding position 231, the lower end of the avoiding position 231 is provided with a limiting frame 232, and the limiting frame 232 is provided with a gap 232a; the blade 220 is disposed in the avoiding portion 231, and the blade 220 at least partially penetrates through the slit 232a; the position-limiting frame 232 is provided in an arc shape protruding downward.

In this embodiment, the blade 220 is disposed on the output shaft of the cutting motor 210, and when the cutting motor 210 works, the output shaft is driven to rotate, so that the blade 220 is driven to rotate to cut the panel of the terminal device. In order to ensure that the blade 220 cuts the panel according to the preset cutting depth to avoid accidentally injuring the components inside the panel, the cutting part 200 is further provided with a limiting plate 230, an avoiding position 231 is arranged on the limiting plate 230 so that the blade 220 extends into the limiting plate 230 through the avoiding position 231, furthermore, a limiting frame 232 integrally formed with the limiting plate 230 is arranged at the lower end of the avoiding position 231, a gap 232a is arranged on the limiting frame 232, and the edge part of the blade 220 penetrates out of the gap 232 a. During the cutting process, the limiting frame 232 abuts against the panel to be cut, and the blade 220 extends out of the gap 232a of the limiting frame 232 to cut the panel. In this way, the distance that the blade 220 penetrates through the slit 232a constitutes the cutting depth of the blade 220 to the panel, so that the cutting depth of the blade 220 is controlled.

Further, since the limiting frame 232 is configured as a downward convex arc, in the cutting process, the arc-shaped limiting frame 232 abuts against the surface of the panel to be cut, and when the surface of the panel changes in height, the arc-shaped surface of the limiting frame 232 correspondingly rises or sinks, so as to guide the cutting part 200 to rise or fall relative to the body part 100, thereby realizing the self-adaptive cutting of the panel.

Optionally, in order to improve the degree of fit between the limiting frame 232 and the blade 220, the embodiment of the present application further provides the following solutions.

Referring to fig. 3 and 10, as shown in fig. 3 and 10, the blade 220 is circular, and the limiting frame 232 is circular; the circle center of the limiting frame 232 coincides with the circle center of the blade 220, and the radius of the limiting frame 232 is the same as that of the blade 220.

In this embodiment, the circular-arc-shaped limiting frame 232 and the circular blade 220 are concentric and have the same radius, so that the blade 220 and the limiting frame 232 have better concentricity, when the limiting frame 232 rises or sinks along the height change of the panel to be cut, the blade 220 moves along with the limiting frame 232, and the point abutted between the limiting frame 232 and the panel is the point where the blade 220 cuts the panel, so that the cutting height of the cutting part 200 and the cutting depth of the blade 220 move cooperatively, and the cutting depth error caused by the suspension of the cutting part 200 on the blade 220 is reduced.

It should be noted that, in different terminal devices, the thicknesses of the boards to be cut are different, which requires that the cutting depth of the blade 220 can be adjusted accordingly to adapt to the situations of different terminal devices. In view of the above, the embodiments of the present application further provide the following technical solutions.

Referring to fig. 2, 3 and 5, as shown in fig. 2, 3 and 5, the cutting part 200 further includes a second mounting plate 240, a second slide rail 250 and an adjusting mechanism 260, wherein the cutting motor 210 and the second slide rail 250 are respectively disposed on the second mounting plate 240, and the limiting plate 230 is slidably connected to the second slide rail 250; the adjustment mechanism 260 is connected to the second mounting plate 240; the limiting plate 230 moves along the second slide rail 250 under the adjustment of the adjusting mechanism 260 to adjust the extent that the blade 220 penetrates out of the gap 232 a.

In this embodiment, the second mounting plate 240 is connected to the first mounting plate 110 through the floating mechanism 300 in a suspending manner, and the cutting motor 210 is disposed on the second mounting plate 240, so as to achieve the cutting function of the cutting head, and further, in order to enable the limiting plate 230 to move relative to the blade 220, the second mounting plate 240 is provided with a second sliding rail 250, so that the limiting plate 230 can slide on the second sliding rail 250. In the specific working process, when the limiting plate 230 slides downwards, the limiting frame 232 descends, the part of the blade 220 penetrating out of the gap 232a of the limiting frame 232 becomes less, and the cutting depth becomes shallow. When the stopper plate 230 slides up and down, the stopper frame 232 rises, and the blade 220 penetrates through the slit 232a of the stopper frame 232 to increase the cutting depth. Therefore, in order to adjust the movement amplitude of the position limiting plate 230 on the second slide rail 250, an adjusting mechanism 260 is provided on the second mounting plate 240, and the movement of the position limiting plate 230 is adjusted by the adjusting mechanism 260, thereby controlling the cutting depth of the blade 220.

In this embodiment, the micrometer 261 is disposed on the first connecting element 241, the second connecting element 233 is disposed between the position-limiting plate 230 and the second sliding rail 250, and optionally, the first connecting element 241 and the second connecting element 233 are disposed in a plate shape and parallel to each other, and when the user rotates the micrometer 261 downwards, the second screw 262 of the micrometer 261 pushes the second connecting element 233, so that the second connecting element 233 moves downwards along the second sliding rail 250, and the position-limiting plate 230 is pushed to move downwards. The third elasticity provides a pulling force that causes the second link 233 to always abut the end of the second screw 262 of the micrometer 261. When the user rotates the micrometer 261 upward, the second link 233 moves upward along the second slide rail 250 by the pulling force of the second elastic member 270, thereby driving the stopper plate 230 to move upward.

Alternatively, the second elastic member 270 is provided as a spring, and the micrometer 261 has a data display screen 263 in addition to the scale display, so that the value of the micrometer 261 can be displayed in real time, and the user can perform precise adjustment.
