[0033] For technologies, methods and devices known to those of ordinary skill in the relevant fields, they may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the specification.

[0034] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0035] It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0036] See Figures 1 to 10As shown in the figure, the present utility model provides a cutting device 100, including: a cutting component 1, the cutting component 1 includes a tool holder 11 and a blade 12, a notch 111 is opened on the bottom side of the tool holder 11, and a groove 112 is arranged on the periphery of the notch 111, and the blade 12 is inserted into the groove 112; a clamping component 2 arranged on the bottom side of the tool holder 11, the clamping component 2 includes a first clamping plate 21 and a second clamping plate 22, the blade 12 is located between the first clamping plate 21 and the second clamping plate 22, and a limiting part 23 is arranged at one end of the inner sides of the first clamping plate 21 and the second clamping plate 22 away from the blade 12.

[0037] Specifically, the cutting device 100 is installed on the edge of the lamp bead board 4 and is used for cutting the waterproof adhesive tape 5 pasted on the edge of the lamp bead board 4. The reason for arranging the waterproof adhesive tape 5 on the edge of the lamp bead board 4 is that the lamp bead board 4 is usually used in outdoor or semi-outdoor environments and is easily affected by rain, moisture or water immersion, as well as erosion by dust, particulate matter and pollutants. In order to protect the circuits and components in the lamp bead board 4 from water erosion and reduce the pollution and damage to the circuits and components, it is necessary to paste the waterproof adhesive tape 5 on the edge of the lamp bead board 4 to form a waterproof layer to prevent water from seeping into the display screen. At the same time, the waterproof adhesive tape 5 can also provide a certain dust-proof sealing effect to prevent dust and impurities from entering the display screen, thereby reducing the pollution and damage to the circuits and components. However, the existing waterproof adhesive tape 5 is too long in width, which will affect the subsequent installation of the side cover. If scissors are directly used to cut the waterproof adhesive tape 5, the length of the waterproof adhesive tape 5 will be uneven. One end of the waterproof adhesive tape 5 is pasted on the inner side of the lamp bead board, and the other end is held by the staff, and the waterproof adhesive tape 5 is in a vertical state. By using the cutting device 100 of the present utility model installed on the upper part of the edge of the lamp bead board 4 and moving the cutting device 100 on the lamp bead board 4, the waterproof adhesive tape 5 in a vertical state can be cut at a unified height.

[0038] See Figure 10 As shown in the figure, specifically, the cutting device 100 includes a cutting component 1 and a clamping component 2. The cutting component 1 is used for cutting and trimming the waterproof adhesive tape 5, and the clamping component 2 is used for clamping and installing on the edge of the lamp bead board 4.

[0039] Specifically, the cutting component 1 includes a tool holder 11 and a blade 12. The tool holder 11 is in the shape of a flat cuboid. A notch 111 is opened in the middle of the upper bottom surface of the tool holder 11 and penetrates to the lower bottom surface, and a groove 112 is opened on the periphery of the notch 111; the blade 12 is inserted into the tool holder 11, and the height of the blade 12 is greater than the depth of the groove 112 at the notch 111, so that the blade 12 can protrude from the groove 112 at the notch 111. When the cutting component 1 performs cutting and trimming, the blade 12 protruding from the groove 112 at the notch 111 can cut and trim the waterproof adhesive tape 5 in a vertical state.

[0040] Specifically, the clamping assembly 2 is arranged on the bottom side of the tool holder 11. The clamping assembly 2 includes a first clamping plate 21 and a second clamping plate 22. The outer sides of the first clamping plate 21 and the second clamping plate 22 are respectively connected to the left and right side surfaces of the tool holder 11. Therefore, the blade 12 is located between the first clamping plate 21 and the second clamping plate 22. At one end of the inner sides of the first clamping plate 21 and the second clamping plate 22 far from the blade 12, a limiting portion 23 is provided, that is, a limiting portion 23 is provided at the bottom ends of the first clamping plate 21 and the second clamping plate 22. In the embodiment of the present invention, the limiting portion 23 at the bottom end of the clamping assembly 2 is engaged with the plate edge of the lamp bead board 4, so as to install the cutting device 100 of the present invention on the plate edge of the lamp bead board 4.

[0041] In an alternative embodiment of the present invention, the tool holder 11 and the clamping assembly 2 are integrally formed.

[0042] Specifically, the tool holder 11 and the clamping assembly 2 are integrally formed. There is no need to use fastening connectors such as bolts to connect between the tool holder 11 and the clamping assembly 2. Therefore, the looseness caused by the loosening of the fastening connectors between the tool holder 11 and the clamping assembly 2 during use is reduced, and the problem of detachment caused by the detachment of the fastening connectors between the tool holder 11 and the clamping assembly 2 during use is also avoided, and the service life can be extended.

[0043] In an alternative embodiment of the present invention, the limiting portion 23 includes a limiting surface 231 and an avoidance surface 232, and the limiting surface 231 is connected to the avoidance surface 232 to form a stepped shape.

[0044] Specifically, the first clamping plate 21 and the second clamping plate 22 are two axially symmetric plate bodies, and the limiting portions 23 provided on the first clamping plate 21 and the second clamping plate 22 are at the same horizontal plane, that is, at the same height. Only in this way can the cutting device 100 be in a stable state when installed on the plate edge of the lamp bead board 4, ensuring the stable installation of the clamping assembly 2 on the lamp bead board 4. This can prevent the occurrence of tilting or instability caused by one side of the limiting portion 23 being higher than the other side. If the limiting portions 23 are not at the same horizontal plane, it may cause excessive pressure on a part of the area, while other areas do not receive sufficient support. Such a design can avoid this uneven stress distribution situation and extend the service life of the equipment. Similarly, the limiting portions 23 being at the same horizontal plane can make the assembly process simpler and faster. The operator does not need to additionally adjust the positions of the two clamping plates to match the lamp bead board 4, thereby improving the production efficiency.

[0045] Specifically, when the cutting device 100 is installed on the lamp bead board 4, the limiting parts 23 of the first clamping plate 21 and the second clamping plate 22 in the clamping assembly 2 are directly in contact with the lamp bead board 4, wherein the limiting surface 231 in the limiting part 23 is located at the upper end of the lamp bead board 4, and the limiting surface 231 pushes and limits the lamp bead board 4 at the top through its protruding corners; the avoiding surface 232 in the limiting part 23 is limited by contacting the two side ends of the lamp bead board 4 and clamping the lamp bead board 4 in the middle.

[0046] Specifically, the limiting surface 231 first contacts the lamp bead board 4 to preliminarily locate the position of the clamping assembly 2 . The limiting surface 231 can help to quickly align the relative position between the clamping assembly 2 and the lamp bead board 4 .

[0047] Specifically, the avoidance surface 232 is located below the limiting surface 231. After the limiting surface 231 completes the initial positioning, the avoidance surface 232 further accurately positions the positional relationship between the clamping assembly 2 and the lamp bead board 4. The distance between the avoidance surfaces 232 of the first clamping plate 21 and the second clamping plate 22 is consistent with the thickness of the lamp bead board 4 installed thereon. This arrangement can achieve precise engagement and effectively prevent the clamping assembly 2 from unnecessary movement or rotation during use.

[0048] The avoidance surface 232 and the limiting surface 231 work together to help ensure that the cutting device 100 is installed on the lamp bead board 4 and remains stable during the cutting process.

[0049] See also Figures 1 to 8 As shown, in an optional embodiment of the present invention, the angle A formed by the inner side surface 24 of the first clamping plate or the second clamping plate and the limiting surface 231 is less than or equal to 90°.

[0050] Specifically, the common lamp bead board 4 is a regular rectangular plate, and the dihedral angle formed by the two contacting surfaces on the lamp bead board 4 is 90°. The angle A formed by the inner side surface 24 of the first clamping plate or the second clamping plate and the limiting surface 231 is used to push and limit the lamp bead board 4; if the angle of the angle A is exactly 90 degrees, the bottom surface of the limiting surface 231 can just contact the upper bottom surface of the top of the lamp bead board 4, and it can be installed on the lamp bead board 4 and form a preliminary limit; if the angle of the angle A is less than 90 degrees, the angle A directly contacts the upper bottom surface of the top of the lamp bead board 4, and the angle A can resist the top of the lamp bead board 4, so that the cutting device 100 can be installed on the lamp bead board 4 and form a preliminary limit; if the angle of the angle A is greater than 90 degrees, the angle A is an obtuse angle, and the limiting surface 231 cannot contact the top surface of the lamp bead board 4, and it cannot be installed on the lamp bead board 4 and form a preliminary limit.

[0051] In an alternative embodiment of the present utility model, a recess is provided at the connection between the limiting surface 231 and the avoiding surface 232, or a root clearing treatment is performed at the connection between the limiting surface and the avoiding surface.

[0052] Specifically, providing a recess at the connection between the limiting surface 231 and the avoiding surface 232 can reduce stress concentration and can also serve as a positioning reference during assembly. Providing the recess and performing the root clearing treatment are to improve the strength, quality, and reliability of the connection part, and also take into account the requirements of the processing technology. Providing a recess or performing a root clearing treatment at the connection between the limiting surface 231 and the avoiding surface 232 can significantly improve the performance and service life of the final product.

[0053] See Figure 1 、 Figure 5 and Figure 9 As shown in

[0054] In an alternative embodiment of the present utility model, the blade 12 is inserted into the groove 112, and the height of the blade 12 is the same as the depth of the groove 112 or the height of the blade 12 is greater than the depth of the groove 112.

[0055] Specifically, when the cutting device 100 is installed on the edge of the lamp bead board 4, by moving the cutting device 100 on the lamp bead board 4, the waterproof tape 5 in a vertical state is cut at a unified height. It is through the blade 12 protruding at the notch 111 that contacts the waterproof tape 5 to cut the waterproof tape 5. Therefore, to achieve the cutting of the waterproof tape 5, the height of the blade 12 and the depth of the groove 112 should be the same or the height of the blade 12 should be greater than the depth of the groove 112. Only by setting it like this can the blade 12 protrude from the groove 112 at the notch 111.

[0056] See Figures 1 to 4 As shown in

[0057] In an alternative embodiment of the present utility model, the inner side surfaces 24 of the first clamping plate 21 and the second clamping plate 22 have concave arc-shaped avoiding grooves 222.

[0058] In addition, a concave arc-shaped avoidance groove 222 is provided on the inner side surface 24 of the first clamping plate 21 and the second clamping plate 22, which can reduce the thickness of the middle parts of the first clamping plate 21 and the second clamping plate 22, so that the first clamping plate 21 and the second clamping plate 22 form a pair of elastic clamping arms for clamping the lamp bead board 4. When in use, the cutting device can be first clamped and fixed on the lamp bead board 4 and then the cutting operation can be carried out.

[0059] The depth of the avoidance groove 222 can be appropriately adjusted according to the elastic force requirements and material conditions.

[0060] See Figure 5 and Figure 10 In an alternative embodiment of the present utility model, the inner side surface 24 of the first clamping plate 21 and the second clamping plate 22 is a straight plane.

[0061] Specifically, this embodiment can be used to cut the waterproof adhesive tape 5 at the bottom of the lamp bead board 4. There is no protruding lamp body and its related wiring at the bottom of the lamp bead board 4. Therefore, the inner side surface 24 of the first clamping plate 21 and the second clamping plate 22 can be set as a flat straight surface. Generally speaking, the vertical distance between the blade 12 and the limiting surface 231 in this embodiment is less than the vertical distance between the blade 12 and the limiting surface 231 of the cutting device 100 with a concave arc-shaped avoidance groove.

[0062] In this embodiment, an inclined groove 13 is provided at the top end of the cutting assembly 1. The inclined groove 13 extends from the inner side edge of the notch 111 to the rear side edge of the upper bottom surface of the cutting assembly 1. An accommodation groove 3 is formed between the clamping assembly 2 and the cutting assembly 1, and the inclined groove 13 inclines towards the accommodation groove 3.

[0063] Specifically, this embodiment can be used to cut the waterproof adhesive tape 5 at the bottom of the lamp bead board 4. Since there is no protruding lamp body at the bottom of the lamp bead board 4, the overall height of the cutting device 100 will be relatively short, which may cause the cut waterproof adhesive tape 5 to be more than the waterproof adhesive tape 5 at the top of the lamp bead board 4. When the cutting device moves to the middle position on the lamp bead board 4, the waterproof adhesive tape 5 may accumulate on the top or front of the tool holder 11, thus affecting the movement and use of the cutting device 100. Therefore, the top end of the tool holder 11 is recessed and designed as an inclined groove 13, which can alleviate the problem of the waterproof adhesive tape 5 accumulating in the front of the cutting device 100.

[0064] The working process of the present utility model is as follows:

[0065] In summary, the embodiment of the present utility model provides a cutting device 100. First, the limiting part 23 located at the bottom of the cutting device 100 is installed at one end of the edge of the lamp bead board 4 to ensure that the cutting device 100 is stably and firmly installed on the edge of the lamp bead board 4. Secondly, the blade 12 is placed in the groove 112, and then the outer ends of the first clamping plate 21 and the second clamping plate 22 in the clamping assembly 2 are held and moved along the edge of the lamp bead board 4. During the movement, the blade 12 continuously cuts the waterproof tape 5 in the vertical state.

[0066] Through the limiting part of the clamping assembly, the present utility model can be clamped and installed on the lamp bead board, so that the present utility model can move along the direction of the lamp bead board, and thus the cutting assembly located above can cut the waterproof tape to be cut on the lamp bead board. The length between the limiting part and the blade in the cutting assembly is the length of the cut waterproof tape. Therefore, the present utility model can also ensure that the height of the cut waterproof tape is consistent, making the specifications of the waterproof tapes in multiple lamp bead board products consistent, solving the problem of inconsistent quality of lamp bead board products. At the same time, the cutting process is simplified and standardized, reducing production costs and improving production efficiency.
