Description

Technical Field

[0001] This utility model relates to the field of liquid crystal glass frame processing technology, specifically to a liquid crystal glass frame processing and cutting device. Background Technology

[0002] In the field of LCD glass bezel cutting, the positioning and clamping accuracy of the workpiece is extremely high. In traditional processing equipment, the spacing adjustment of the clamping mechanism is mostly done by manual lead screw or by driving the two side mechanisms separately. Such methods are cumbersome, time-consuming, and difficult to ensure the synchronicity of the movement on both sides, which can easily lead to clamping position deviation and affect the subsequent cutting accuracy. In existing manual adjustment structures, operators need to rotate the adjustment handwheels on both sides separately and control the position of the two clamping mechanisms by observing the scale or using measuring tools. This method is not only inefficient, but also highly susceptible to human factors and prone to adjustment errors. In addition, if the feed speeds on both sides are inconsistent, it will cause uneven clamping force, causing the frame to tilt or stress concentration. In severe cases, it may cause the frame of brittle materials to crack before processing. Utility Model Content

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0020] Example 1 Reference Figure 1-4 The first embodiment of this utility model provides a cutting assembly 1 including a control panel 101, an operating table 102, and a cutting machine 103. The control panel 101 is disposed on one side of the front end of the operating table 102. The surface of the operating table 102 is fixedly connected to the surface of the cutting machine 103. Two sets of adjustment mechanisms 2 are provided on the operating table 102. Clamping mechanisms 4 are provided on the adjustment mechanisms 2. The adjustment mechanisms 2 are used to adjust the distance between the two sets of clamping mechanisms 4. The clamping mechanisms 4 are used to fix the frame.

[0021] Specifically, this utility model solves the problems of inconvenient clamping spacing adjustment, poor positioning accuracy, and uneven clamping force in traditional cutting equipment by setting an adjustment mechanism 2 composed of a servo motor 202, a double-headed screw 301, and a transmission assembly, in conjunction with a stepper motor 406 and an adjustment screw 405 in the clamping mechanism 4. It achieves rapid adaptation and stable clamping of LCD glass frames of different sizes, effectively avoids workpiece displacement or vibration during processing, improves cutting accuracy and operational safety, and enhances the versatility and automation of the equipment.

[0022] Furthermore, once the frame is securely clamped, the cutting process can begin. At this point, the cutting machine 103 installed on the operating table 102 is started, allowing it to precisely cut the fixed frame according to the preset processing path and parameters. Throughout the entire processing, the clamping mechanism 4 continuously provides stable support and positioning, ensuring the accuracy of the cutting trajectory and the flatness of the processed surface.

[0023] Example 2 In a second embodiment of this utility model, an adjustment mechanism 2 is provided, comprising a protective box 201, a servo motor 202, a driving gear 203, and a driven gear 204. The inner wall of the protective box 201 is rotatably connected to the output end of the servo motor 202, and the output end of the servo motor 202 is fixedly connected to the inner wall of the driving gear 203. The tooth surface of the driving gear 203 meshes with the tooth surface of the driven gear 204. The surface of the protective box 201 is fixedly connected to the front end of the operating table 102, and the surface of the servo motor 202 is fixedly connected to the lower end of the operating table 102. The driving gear 203 and the driven gear 204 are connected in a meshing manner. All wheels 204 are housed inside the protective box 201. The adjusting mechanism 2 is equipped with a mating mechanism 3, which includes a double-ended screw 301, a transmission plate 302, and a connecting sleeve 303. The surface of the double-ended screw 301 is threadedly connected to the inner wall of the transmission plate 302. Both ends of the transmission plate 302 are fixedly connected to the surfaces of the two connecting sleeves 303 respectively. The inner wall of the driven gear 204 is fixedly connected to the front end of the double-ended screw 301. The surface of the transmission plate 302 is slidably connected to the inner wall of the operating table 102 through a sliding groove. Both ends of the double-ended screw 301 are rotatably connected to the inner wall of the operating table 102.

[0024] Specifically, this utility model solves the problems of low efficiency, poor synchronization, and easy error in traditional manual adjustment of clamping distance by setting an adjustment mechanism 2 composed of a servo motor 202, a gear set, and a double-ended screw 301, and cooperating with a transmission plate 302, a connecting sleeve 303, and a sliding structure. The servo motor 202 drives the active gear 203 to drive the driven gear 204 and the double-ended screw 301 to rotate. By utilizing the synchronous transmission of the reverse threads at both ends of the double-ended screw 301, the two connecting sleeves 303 and the clamping mechanism 4 are moved at equal distances and in the same direction, ensuring that the adjustment process is stable, accurate, and responsive. The protective box 201 effectively protects the transmission components, reduces the impact of dust and vibration, and improves the reliability and service life of the mechanism.

[0025] Furthermore, after adjusting the spacing of the clamping mechanisms 4, the workpiece clamping stage begins. The LCD glass frame to be processed is placed stably on the support platform 402 at the top of the two clamping mechanisms 4, ensuring that its position is centered and meets the processing requirements. Subsequently, the stepper motor 406 installed below the support platform 402 is started through the control panel 101. The stepper motor 406 drives the adjusting screw 405 connected to its output end to rotate. The adjusting screw 405 is connected to the clamping plate 404 by a threaded engagement. As the adjusting screw 405 rotates, the clamping plate 404 moves downward in the vertical direction, gradually approaching and finally making close contact with the upper surface of the frame, applying a stable clamping force, thereby achieving reliable fixation of the workpiece and providing necessary stability for subsequent cutting processes.

[0026] Example 3 The third embodiment of this utility model provides a clamping mechanism 4 including a bearing rod 401, a support platform 402, a guide rod 403, a clamping plate 404, an adjusting screw 405, and a stepper motor 406. The upper end of the bearing rod 401 is fixedly connected to the lower end of the support platform 402. The outer inner wall of the support platform 402 is slidably connected to the surface of the guide rod 403. The upper end of the guide rod 403 is fixedly connected to the inner wall of the clamping plate 404. The inner wall of the clamping plate 404 is threadedly connected to the surface of the adjusting screw 405. The lower end of the adjusting screw 405 is fixedly connected to the output end of the stepper motor 406. The surface of the bearing rod 401 is fixedly connected to the inner wall of the connecting sleeve 303. The surface of the bearing rod 401 is slidably connected to the inner wall of the operating table 102 through a sliding groove. The surface of the stepper motor 406 is fixedly connected to the lower end of the support platform 402. The lower end of the adjusting screw 405 is rotatably connected to the inner wall of the support platform 402.

[0027] Specifically, this utility model solves the problems of uneven force application, easy damage to the surface of the LCD glass frame, and insufficient clamping reliability of traditional clamping methods by setting up a clamping mechanism 4 composed of a stepper motor 406, an adjusting screw 405, a guide rod 403, and a clamping plate 404. The stepper motor 406 precisely controls the rotation of the adjusting screw 405, driving the clamping plate 404 to rise and fall vertically along the guide rod 403, realizing controllable adjustment of the clamping force, ensuring that the frame is evenly stressed and firmly fixed. The structure of the guide rod 403 effectively prevents the clamping plate 404 from deflecting during the movement, improving the straightness and stability of the clamping, avoiding displacement or vibration of the workpiece during the cutting process, and ensuring processing accuracy and safety.

[0028] Furthermore, in the initial stage of LCD glass frame cutting and processing, the servo motor 202 located at the lower end of the operating table 102 is first started through the control panel 101. The output end of the servo motor 202 is connected to the drive gear 203, which meshes with the driven gear 204 installed at the front end of the double-ended screw 301. When the servo motor 202 is running, the power is transmitted to the double-ended screw 301 through the gear transmission, causing it to rotate synchronously. Since the two ends of the double-ended screw 301 are respectively machined with threads of opposite directions, its rotation will drive the two transmission plates 302 that are threaded with it to move in opposite directions along the axial direction. The movement of the transmission plates 302 further drives the connecting sleeves 303 connected to them to slide synchronously on the guide rail inside the operating table 102, thereby realizing the precise adjustment of the position of the clamping mechanisms 4 on both sides.

[0029] Working principle: In the initial stage of LCD glass frame cutting, the servo motor 202 located at the lower end of the operating table 102 is first started via the control panel 101. The output end of the servo motor 202 is connected to the drive gear 203, which meshes with the driven gear 204 installed at the front end of the double-ended screw 301. When the servo motor 202 runs, the power is transmitted to the double-ended screw 301 via gear transmission, causing it to rotate synchronously. Since the two ends of the double-ended screw 301 are respectively machined with threads of opposite directions, its rotation will drive the two transmission plates 302 that are threaded with it to move axially in opposite directions. The movement of the transmission plates 302 further drives the connecting sleeves 303 connected to them to slide synchronously on the guide rails inside the operating table 102, thereby achieving precise adjustment of the position of the clamping mechanisms 4 on both sides. After the adjustment of the spacing of the clamping mechanisms 4 is completed, the workpiece clamping stage begins, and the LCD glass frame to be processed is placed stably on the support platform at the top of the two clamping mechanisms 4. On platform 402, ensure its position is centered and meets processing requirements. Then, start the stepper motor 406 installed below the support platform 402 via control panel 101. The stepper motor 406 drives the adjusting screw 405 connected to its output end to rotate. The adjusting screw 405 is connected to the clamping plate 404 by a threaded engagement. As the adjusting screw 405 rotates, the clamping plate 404 moves downward in the vertical direction, gradually approaching and finally making close contact with the upper surface of the frame, applying a stable clamping force to achieve reliable fixation of the workpiece and provide necessary stability for subsequent cutting processes. Once the frame is firmly clamped, the cutting process can begin. At this time, start the cutting machine 103 installed on the operating table 102 to accurately cut the fixed frame according to the preset processing path and parameters. Throughout the processing, the clamping mechanism 4 continuously provides stable support and positioning to ensure the accuracy of the cutting trajectory and the flatness of the processed surface.

[0030] In summary: By using a servo motor, drive gear, and driven gear to rotate the double-headed screw, and coordinating with the synchronous movement of the transmission plate and connecting sleeve, precise adjustment of the distance between the two sets of clamping mechanisms is achieved; by using a stepper motor to drive the adjusting screw to rotate, the clamping plate moves vertically downward, achieving stable clamping of the LCD glass frame; finally, with the synergistic effect of the clamping system and the cutting machine, accurate positioning, reliable fixing, and efficient cutting of the frame are completed, realizing automation and high-precision operation of the cutting process.
