[0013] Further technical solution: The cleaning mechanism includes fan blades and a rotating shaft, the rotating shaft being rotatably connected to the device body, the fan blades being sleeved on the end of the rotating shaft and fixedly connected to the rotating shaft, and further comprising:

[0014] The drive assembly is connected to the rotating shaft via a transmission pair and is used to drive the rotating shaft to rotate in the vertical direction.

[0015] Further technical solution: The drive assembly includes a push column and a spiral groove. The push column is fixedly connected to one end of the first guide rod extending into the sleeve. The spiral groove is formed inside the sleeve. The push column and the spiral groove are slidably engaged. The sleeve is connected to the rotating shaft through a transmission pair.

[0019] Further technical solution: The elastic element is a spring, compression spring, elastic steel plate or other elastic element with elastic contraction performance.

[0020] The cutting method of the above-mentioned display screen cutting device includes the following steps:

[0021] S1. The relevant technicians start the linear motion component to pull the carrier seat to make a linear motion in the vertical direction. At this time, the carrier seat pushes the pressing limit block to press against the display screen located on the device body. At this time, the display screen gives a reaction force to the pressing limit block. This reaction force pushes the pressing limit block to squeeze the elastic element and make a linear motion in the vertical direction along the carrier seat under the guidance of the guide component, so as to press and limit the display screen on the device body for the cutting component to perform cutting processing.

[0023] S3. Use the cutting component to cut the display screen that is limited to the device body by the pressing and limiting mechanism.

[0024] Beneficial effects

[0025] This invention provides a display screen cutting device and method, which have the following advantages compared with the prior art:

[0026] 1. In this invention, the relevant technicians activate the linear motion component to pull the support seat to perform linear motion in the vertical direction. At this time, the support seat pushes the pressing limit block to press against the display screen located on the device body. The display screen then exerts a reaction force on the pressing limit block. This reaction force pushes the pressing limit block to squeeze the elastic element and, under the guidance of the guide component, performs linear motion in the vertical direction along the support seat, thereby pressing and limiting the display screen onto the device body for the cutting component to perform cutting. At the same time, the relevant technicians can also clean the surface of the display screen to be cut through the cleaning mechanism to prevent the display screen from breaking due to debris on its surface when the cutting component cuts the display screen.

[0027] 2. In this invention, the pressing and limiting block pushes the first guide rod to move linearly in the vertical direction along the length of the sleeve. The first guide rod pushes the pushing column to slide along the spiral groove. At this time, the pushing column squeezes the inner wall of the spiral groove, causing the sleeve to rotate in the vertical direction. At this time, the sleeve drives the rotating shaft to rotate in the vertical direction through the transmission pair. The rotating shaft drives the fan blade to rotate in the vertical direction to form negative pressure, so as to achieve the technical effect of the pressing and limiting component limiting the display screen on the device body while driving the cleaning mechanism to perform negative pressure dust removal on the surface of the display screen.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0035] Please see Figures 1-3 According to one embodiment of the present invention, a display screen cutting device includes a device body 1, a support 2, and a cutting assembly 4 for cutting the display screen. The support 2 is fixedly connected to the output end of a linear motion component 3 fixedly connected to the device body 1. The device also includes:

[0036] The pressing and limiting mechanism 5, mounted on the support 2, is used to press and limit the display screen to be cut; and

[0037] The cleaning mechanism 6, mounted on the support 2, is used to clean the surface of the display screen to be cut.

[0038] The pressing and limiting mechanism 5 includes a pressing and limiting block 501 and an elastic element 502. The pressing and limiting block 501 is in a limiting sliding cooperation with the support seat 2. The two ends of the elastic element 502 are fixedly connected to the pressing and limiting block 501 and the support seat 2, respectively. It also includes:

[0039] The guide assembly 503 is mounted on the support 2 and is used to guide the pressing limit block 501.

[0040] Preferably, the guide assembly 503 includes a first guide rod 5031 and a sleeve 5032. One end of the first guide rod 5031 is fixedly connected to the pressing limit block 501, and the other end of the first guide rod 5031 extends into the sleeve 5032. The first guide rod 5031 and the sleeve 5032 are slidably engaged, and the sleeve 5032 is rotatably connected to the support seat 2. The purpose of this arrangement is to limit and guide the pressing limit block 501 by using the first guide rod 5031, which is fixedly connected to the pressing limit block 501 and slidably engaged with the sleeve 5032, which is fixedly connected to the support seat 2, to prevent the pressing limit block 501 from tilting when it slides linearly along the support seat 2.

[0041] Preferably, the linear motion component 3 is an electric telescopic rod. Those skilled in the art should know that the purpose of this configuration is to push the support seat 2 to perform linear movement in the vertical direction relative to the device body 1. Therefore, in some embodiments, the linear motion component 3 can also be any one of a hydraulic cylinder, a pneumatic cylinder, and a linear motor.

[0042] Preferably, the elastic element 502 is a spring. Those skilled in the art should know that the purpose of this arrangement is to provide flexible elastic support for the pressing limit block 501. Therefore, in some embodiments, the elastic element 502 can also be a compression spring, an elastic steel plate, or other elastic elements with elastic contraction properties.

[0043] In this embodiment of the invention, the relevant technicians activate the linear motion component 3 to pull the support seat 2 to perform linear motion in the vertical direction. At this time, the support seat 2 pushes the pressing limit block 501 to press against the display screen located on the device body 1. The display screen then exerts a reaction force on the pressing limit block 501. This reaction force pushes the pressing limit block 501 to squeeze the elastic component 502 and, under the guidance of the guide component 503, performs linear motion in the vertical direction along the support seat 2, thereby pressing and limiting the display screen onto the device body 1 for the cutting component 4 to perform cutting. At the same time, the relevant technicians can also clean the surface of the display screen to be cut using the cleaning mechanism 6 to prevent the display screen from breaking due to debris on its surface when the cutting component 4 cuts the display screen.

[0044] Please see Figures 1-3 As an embodiment of the present invention, the cleaning mechanism 6 includes a fan blade 601 and a rotating shaft 602. The rotating shaft 602 is rotatably connected to the device body 1. The fan blade 601 is sleeved on the end of the rotating shaft 602 and fixedly connected to the rotating shaft 602. The mechanism also includes:

[0045] The drive assembly is connected to the rotating shaft 602 via the transmission pair 603 and is used to drive the rotating shaft 602 to rotate in the vertical direction.

[0046] Preferably, the drive assembly includes a push post (not shown in the figure) and a spiral groove (not shown in the figure). The push post is fixedly connected to one end of the first guide rod 5031 extending into the sleeve 5032. The spiral groove is formed in the sleeve 5032. The push post and the spiral groove are slidably engaged. The sleeve 5032 is connected to the rotating shaft 602 through a transmission pair 603. The pressing limit block 501 pushes the first guide rod 5031 to move linearly in the vertical direction along the length of the sleeve 5032. The first guide rod 5031 pushes the push column to slide along the spiral groove. At this time, the push column squeezes the inner wall of the spiral groove, causing the sleeve 5032 to rotate in the vertical direction. At this time, the sleeve 5032 drives the rotating shaft 602 to rotate in the vertical direction through the transmission pair 603. The rotating shaft 602 drives the fan blade 601 to rotate in the vertical direction to form negative pressure, so as to achieve the technical effect of pressing the limit component to limit the display screen on the device body 1 while driving the cleaning mechanism 6 to perform negative pressure dust removal on the surface of the display screen.

[0047] Preferably, the transmission pair 603 is a pulley pair. Those skilled in the art should know that the purpose of this arrangement is to convert the rotational motion of the sleeve 5032 in the vertical direction into the rotational motion of the shaft 602 in the vertical direction. Therefore, in some embodiments, the transmission pair 603 can also be set as a gear pair or a sprocket pair.

[0048] In this embodiment of the invention, the pressing limiting block 501 in the pressing limiting assembly pushes the first guide rod 5031 to move linearly in the vertical direction along the length of the sleeve 5032. The first guide rod 5031 pushes the push column to slide along the spiral groove. At this time, the push column squeezes the inner wall of the spiral groove, causing the sleeve 5032 to rotate in the vertical direction. At this time, the sleeve 5032 drives the rotating shaft 602 to rotate in the vertical direction through the transmission pair 603. The rotating shaft 602 drives the fan blade 601 to rotate in the vertical direction to form negative pressure, so as to achieve the technical effect of the pressing limiting assembly limiting the display screen on the device body 1 while driving the cleaning mechanism 6 to perform negative pressure dust removal on the surface of the display screen.

[0049] Please see Figures 1-2 As an embodiment of the present invention, the cutting assembly includes a cutting blade 401 and a blade holder 402. The blade holder 402 is fixedly connected to the support base 2, and the cutting blade 401 is detachably connected to the cutting blade 401.

[0050] In this embodiment of the invention, the cutting blade 401 moves linearly in the vertical direction under the push of the support seat 2, thereby achieving the technical effect of using the cutting blade 401 to press against the display screen and cut the display screen.

[0051] As an alternative to the above example, the cutting assembly 4 includes a mounting frame, a motor, a lead screw, a second guide rod, a mounting base, and a cutting machine. The mounting frame is fixedly connected to the support base 2. The lead screw is rotatably connected to the mounting frame. The motor is detachably connected to the mounting frame, and its output end is connected to the lead screw via a coupling. The mounting base, which slides against the second guide rod fixedly connected to the mounting frame, is bolted to the lead screw. The cutting machine is detachably connected to the mounting base. The purpose of this arrangement is to utilize the motor to drive the lead screw to rotate horizontally, the lead screw to push the mounting base to move linearly along the second guide rod, the mounting base to push the cutting machine to move synchronously linearly, and the support base 2 to push the cutting machine against the display screen, thereby achieving the technical effect of cutting the display screen.

[0052] The cutting method of the above-mentioned display screen cutting device includes the following steps:

[0053] S1. The relevant technicians start the linear motion component 3 to pull the support seat 2 to make a linear motion in the vertical direction. At this time, the support seat 2 pushes the pressing limit block 501 to press against the display screen located on the device body 1. At this time, the display screen gives the pressing limit block 501 a reaction force. The reaction force pushes the pressing limit block 501 to squeeze the elastic component 502 and make a linear motion in the vertical direction along the support seat 2 under the guidance of the guide component 503, so that the display screen is pressed and limited on the device body 1 for the cutting component 4 to perform cutting processing.

[0054] S2. Activate the cleaning mechanism 6 to clean the surface of the display screen that is about to be cut;

[0055] S3. The display screen, which is fixed to the device body 1 by the pressing and limiting mechanism 5, is cut using the cutting component 4.
