Technical Field

[0001] This utility model belongs to the field of LCD processing technology, and specifically relates to a cutting tool for LCD panel processing. Background Technology

[0002] An LCD panel is an electronic display device that uses the principle of liquid crystal materials changing their light transmittance under voltage to display images. As an important display technology, with continuous technological advancements, LCD panels have seen significant improvements in resolution, color performance, and response speed, further consolidating their dominant position in the display market.

[0003] During the production and processing of LCD panels, cutting equipment is needed to cut them into multiple panels of the appropriate size. Currently, the cutting tools used for LCD panel processing usually do not have a blade tip protection structure. Often, when placing the LCD panel, the blade tip will be accidentally touched, which will not only damage the blade tip, but also damage the edges of the LCD panel.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a cutting tool for LCD panel processing.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a cutting tool for LCD panel processing, which can solve the problem that existing LCD panel processing tools do not have a tool tip protection structure.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a cutting tool for LCD panel processing, comprising: a housing, a lifting rod slidably disposed within the housing, a first mounting head fixed to the bottom of the lifting rod, a rotating shaft mounted on the first mounting head, a diamond cutter rotatably disposed on the rotating shaft, a pair of control rods inserted into the upper end of the housing, a second mounting head fixed to one end of each pair of control rods located inside the housing, a gear mounted on each pair of second mounting heads, a first toothed plate fixed to the two inner sidewalls of the housing near the pair of gears, a second toothed plate fixed to the two sidewalls of the lifting rod near the pair of gears, the gears meshing with the first and second toothed plates, a fixing plate fixed to one end of each pair of control rods located outside the housing, a connecting head mounted on the fixing plate, and a spring mounted on each pair of control rods between the fixing plate and the housing.

[0008] In one or more embodiments of this utility model, sliders are fixed on both sides of the lifting rod, and a pair of slide rails adapted to the sliders are fixed on the two inner side walls of the outer shell. The lifting rod slides on the slide rails through the sliders to achieve sliding arrangement with the outer shell.

[0009] In one or more embodiments of this utility model, a pair of third mounting heads are fixed to the bottom of the outer shell, and each of the third mounting heads is equipped with an auxiliary pulley. The auxiliary pulley is used to assist the diamond cutter in cutting, and the end of the auxiliary outer shell close to the LCD panel moves on the surface of the LCD panel.

[0010] In one or more embodiments of this utility model, a pair of sliding sleeves are fixed to the top of the outer casing, and a pair of control rods slide in the pair of sliding sleeves respectively. The control rods are vertically slidable between themselves and the outer casing through the sliding sleeves.

[0011] In one or more embodiments of this utility model, the connector head is provided with multiple clamping grooves, each of which is equipped with an elastic clamping body. The connector head is externally threaded with a fastening ring, and a limit head is fixed at the top of the connector head. After the fastening ring is turned to the outside of the elastic clamping body, the fastening ring clamps the elastic clamping body onto the connecting rod inserted in the connector head, thereby installing the device onto the connecting rod.

[0012] In one or more embodiments of this utility model, the end of the elastic clamp is fixed with an anti-slip head. The radius of the arc of the inner sidewall of the anti-slip head is smaller than the radius of the arc of the inner sidewall of the connector. Because the radius of the arc of the inner sidewall of the anti-slip head is smaller than the radius of the arc of the inner sidewall of the connector, the elastic clamp is clamped on the connecting rod when the fastening ring moves to the outside of the elastic clamp.

[0013] Compared with the prior art, this utility model, through its related structural design, can effectively protect the cutting head when it is not being processed, thereby effectively improving the service life of the cutting head. Attached Figure Description

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0024] like Figure 1-6 As shown, an embodiment of the present invention provides a cutting tool for processing LCD panels, comprising: a housing 1, a lifting rod 101 slidably disposed within the housing 1, and a first mounting head 102 fixed to the bottom of the lifting rod 101. A rotating shaft 104 is mounted on the first mounting head 102, and a diamond cutter 103 is rotatably disposed on the rotating shaft 104. The lifting rod 101 drives the diamond cutter 103 to slide downward from the housing 1 through the first mounting head 102, so that the diamond cutter 103 contacts the LCD panel for cutting.

[0025] like Figure 1-6As shown, a pair of control levers 105 are inserted into the upper end of the outer casing 1. A second mounting head 106 is fixed to one end of each control lever 105 inside the outer casing 1. Gears 107 are mounted on each of the second mounting heads 106. First toothed plates 108 are fixed to the two inner sidewalls of the outer casing 1 near the gears 107. Second toothed plates 109 are fixed to the two sidewalls of the lifting rod 101 near the gears 107. The gears 107 mesh with the first toothed plates 108 and the second toothed plates 109. A fixing plate 115 is fixed to one end of each control lever 105 outside the outer casing 1. A connector 117 is mounted on the fixing plate 115. Springs 116 are mounted on each control lever 105 between the fixing plate 115 and the outer casing 1.

[0026] like Figure 1-6 As shown, connector 117 is used to connect to a cutting device. When the cutting device processes the LED panel, the cutting tool moves up and down via a lifting device on the cutting device. Connector 117 drives a pair of control rods 105 downward via fixing plate 115. The pair of control rods 105 drive the housing 1 downward. After the housing 1 reaches the bottom and contacts the LCD panel, the housing 1 stops moving downward. At this time, the pair of control rods 105 continue to move downward. The control rods 105 drive gear 107 downward via second mounting head 106. When gear 107 moves downward, first toothed plate 108 causes gear 107 to rotate. While gear 107 rotates, a pair of second toothed plates 109 drive lifting rod 101 downward, thereby causing lifting rod 101 to drive diamond cutter 103 downward to contact the LCD panel. The elastic force of spring 116 is used to push housing 1 away from fixing plate 115.

[0027] like Figure 3-4 As shown, sliders 112 are fixed on both sides of the lifting rod 101, and a pair of slide rails 113 adapted to the sliders 112 are fixed on the two inner side walls of the outer casing 1. The lifting rod 101 slides on the slide rails 113 through the sliders 112 to achieve sliding setting with the outer casing 1.

[0028] like Figure 1-3 As shown, a pair of third mounting heads 110 are fixed to the bottom of the outer casing 1, and each of the third mounting heads 110 is equipped with an auxiliary pulley 111. The auxiliary pulley 111 is used to assist the diamond cutter 103 in cutting the LCD panel, and the end of the auxiliary casing near the LCD panel moves on the surface of the LCD panel. A pair of sliding sleeves 114 are fixed to the top of the outer casing 1, and a pair of control rods 105 slide in the pair of sliding sleeves 114 respectively. The control rods 105 are vertically slidable between themselves and the outer casing 1 through the sliding sleeves 114.

[0029] like Figure 5-6As shown, the connector 117 has multiple clamping grooves 120, and each clamping groove 120 is fitted with an elastic clamping body 121. A fastening ring 118 is threaded onto the connector 117. A limit head 119 is fixed to the top of the connector 117. After the fastening ring 118 is rotated to the outside of the elastic clamping body 121, the fastening ring 118 clamps the elastic clamping body 121 onto the connecting rod inserted in the connector 117, thereby installing the device onto the connecting rod.

[0030] like Figure 5-6 As shown, an anti-slip head 122 is fixed to the end of the elastic clamp 121. The radius of the arc of the inner wall of the anti-slip head 122 is smaller than the radius of the arc of the inner wall of the connector 117. Because the radius of the arc of the inner wall of the anti-slip head 122 is smaller than the radius of the arc of the inner wall of the connector 117, the elastic clamp 121 is clamped onto the connecting rod when the fastening ring 118 moves to the outside of the elastic clamp 121.

[0031] Working principle: This device needs to be installed onto the connecting rod of the lifting cylinder on the cutting device. During installation, insert the connecting rod into the connector 117. Because the radius of curvature of the inner wall of the anti-slip head 122 is smaller than that of the inner wall of the connector 117, the elastic clamp 121 is pushed outwards. Then, turn the fastening ring 118 to the outside of the elastic clamp 121. After turning the fastening ring 118 to the outside of the elastic clamp 121, the elastic clamp 121 is clamped inwards, clamping the anti-slip head 122 onto the connecting rod, thus completing the installation.

[0032] When cutting an LCD panel, the device moves downward via the connecting rod of the lifting cylinder. Control rod 105 moves the outer casing 1 downward until the auxiliary pulley 111 contacts the LCD panel, at which point the outer casing 1 stops moving downward. Meanwhile, a pair of control rods 105 continue to move downward. Control rod 105 drives gear 107 downward via the second mounting head 106. As gear 107 moves downward, the first toothed plate 108 causes it to rotate. Simultaneously, the rotation of gear 107 drives the lifting rod 101 downward via a pair of second toothed plates 109. This causes the lifting rod 101 to move the diamond cutter 103 downward until it contacts the LCD panel, allowing the device to move and cut on the LCD panel.

[0033] After the cutting is completed, the connecting rod of the lifting cylinder moves the device upward. Under the action of its own weight and the elastic force of the spring 116, the outer shell 1 moves downward relative to the control rod 105. At this time, the first gear plate 108 causes the gear 107 to rotate again. While the pair of gears 107 are rotating, the lifting rod 101 is moved upward through the pair of second gear plates 109. The lifting rod 101 drives the diamond cutter 103 to retract into the outer shell 1, thereby protecting the diamond cutter 103 from the outer shell 1.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
