Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, and in particular to a positioning tooling for OLED display processing. Background Technology

[0002] As is well known, OLED displays, or Organic Light Emitting Diode displays, are a self-emissive display technology that does not rely on a backlight module. Its core is to coat multiple layers of organic light-emitting materials on a glass or flexible substrate. When current passes through, the organic materials directly convert electrical energy into light energy and emit light. Different pixels can independently control brightness and color to present images. Because the glass substrate of OLED displays is thin and brittle, the organic light-emitting layer is easily damaged, and the processing (such as cutting, cover plate bonding, and pixel detection) requires alignment, its processing cannot rely on manual positioning. The positioning fixture solves the subsequent processing needs through flexible limiting blocks.

[0003] However, traditional positioning fixtures for OLED display manufacturing typically have limit block positions that are preset for specific screen sizes and cannot be flexibly adapted to different lengths and widths.

[0004] Therefore, those skilled in the art have provided a positioning fixture for OLED display processing to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning fixture for OLED display processing. In use, a servo motor drives a bidirectional screw to rotate, which, in conjunction with a guide rod, causes the sliding rod to slide the side clamping plates in opposite directions. A synchronous motor drives a bidirectional screw to adjust the sliding frame and the front clamping plate in opposite directions, allowing for flexible adjustment of the lateral and front clamping distances. This easily adapts to OLED screens of different sizes. Furthermore, by rotating a knob to move the side clamping plates, adjustments can be made according to the thickness of the display screen, further improving the stability of the clamping and positioning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A positioning fixture for OLED display processing includes a worktable. Support rods are fixedly connected to the front and rear ends of both sides of the worktable's outer wall. Storage slots are formed on the outer walls of opposite ends of the support rods. A servo motor is fixedly connected to one side of the inner wall of the front storage slot. A bidirectional screw is fixedly connected to the output end of the servo motor. Guide rods are fixedly connected to both sides of the inner wall of the rear storage slot. Slide rods are threaded and slidably connected to both sides of the outer walls of the bidirectional screw and guide rod. Mounting slots are formed on the outer walls of adjacent ends of the slide rods. A screw is rotatably connected to the center of the bottom surface of the front mounting slot. A guide rod is fixedly connected to the bottom surface of the rear mounting slot. Sliding sleeves are slidably and threadedly connected to the outer walls of the guide rods and screws. Side clamps are fixedly connected to the outer walls of adjacent sides of the sliding sleeves. The upper part of both sides of the outer wall of the workbench is provided with a placement slot. The rear end of the inner wall of the placement slot is fixedly connected to a synchronous motor. The output end of the synchronous motor is fixedly connected to a bidirectional screw. Both ends of the outer wall of the bidirectional screw are threadedly connected to a sliding frame. The outer wall of the adjacent side of the sliding frame is fixedly connected to a positive clamping plate.

[0007] Compared with existing positioning fixtures for OLED display processing, this positioning fixture uses a servo motor to drive a bidirectional screw to rotate, which, together with a guide rod, causes the slide bar to slide the side clamping plate in opposite directions. A synchronous motor drives a bidirectional screw to adjust the sliding frame and the front clamping plate in opposite directions, allowing for flexible adjustment of the side and front clamping distances. This easily adapts to OLED screens of different sizes. Furthermore, by rotating a knob to move the side clamping plate, adjustments can be made according to the thickness of the display screen, further improving the stability of the clamping and positioning.

[0008] Furthermore, support legs are fixedly connected to the four corners of the lower surface of the workbench; The above technical solution uses supporting legs to improve overall stability.

[0009] Furthermore, a control console is fixedly connected to one side of the outer wall of the front end of the workbench, and a PLC control panel is embedded in the upper surface of the control console. The PLC control panel is electrically connected to the servo motor and the synchronous motor respectively. The above technical solution allows for electrical connection between the PLC control panel and the servo motor and synchronous motor, respectively, facilitating their switching.

[0010] Furthermore, a pad is fixedly connected to the middle of the upper surface of the workbench; The above technical solution uses a pad to cushion the placement of the display screen.

[0011] Furthermore, each of the sliding rods slides in opposite directions on the inner wall of the storage slot; With the above technical solution, the slide bars slide in opposite directions on the inner wall of the storage slot, which facilitates clamping the two sides of the display screen.

[0012] Furthermore, the upper ends of the screws all pass through the mounting grooves to the upper part of the slide rods and are all fixedly connected with knobs; The above technical solution allows the screw to be easily rotated via a knob.

[0013] Furthermore, each of the sliding frames slides in opposite directions on the inner wall of the placement slot; The above technical solution allows for easy front and rear clamping of the display screen using a sliding frame.

[0014] This utility model has the following beneficial effects: 1. The positioning fixture for OLED display processing proposed in this utility model, compared with the existing positioning fixtures for OLED display processing, uses a servo motor to drive a bidirectional screw to rotate, which, together with a guide rod, causes the slide rod to slide the side clamping plate in opposite directions. A synchronous motor drives a bidirectional screw to adjust the sliding frame and the front clamping plate in opposite directions, allowing for flexible adjustment of the side and front clamping distances. This easily adapts to OLED screens of different sizes. By rotating the knob to move the side clamping plate, further adjustments can be made according to the thickness of the display screen, further improving the stability of clamping and positioning.

Slide rods 25 are threaded and slidably connected to both sides of the outer walls of the bidirectional screw 23 and the guide rod 24. Mounting slots 26 are opened on the outer walls of adjacent ends of the slide rods 25. A screw 27 is rotatably connected to the middle of the bottom surface of the front mounting slot 26. A guide rod 29 is fixedly connected to the bottom surface of the rear mounting slot 26. Sliding sleeves 210 are slidably and threadedly connected to the outer walls of the guide rods 29 and the screw 27. Side clamps 211 are fixedly connected to the outer walls of adjacent sides of the sliding sleeves 210. The upper part of both sides of the outer wall of the workbench 1 is provided with a placement groove 3. The rear end of the inner wall of the placement groove 3 is fixedly connected to a synchronous motor 31. The output end of the synchronous motor 31 is fixedly connected to a double-acting screw 32. Both ends of the outer wall of the double-acting screw 32 are threadedly connected to a sliding frame 33. The outer wall of the adjacent side of the sliding frame 33 is fixedly connected to a positive clamping plate 34.

[0019] Compared with existing positioning fixtures for OLED display processing, this positioning fixture uses a servo motor 22 to drive a bidirectional screw 23 to rotate, which, together with a guide rod 24, causes the slide rod 25 to slide the side clamping plate 211 in opposite directions. A synchronous motor 31 drives a bidirectional screw 32 to cause the slide frame 33 to adjust the front clamping plate 34 in opposite directions. This allows for flexible adjustment of the lateral and front clamping distances, easily adapting to OLED screens of different sizes. Furthermore, by rotating the knob 28 to move the side clamping plate 211, adjustments can be made according to the thickness of the display screen, further improving the stability of the clamping and positioning.

[0020] Support legs 11 are fixedly connected to the four corners of the lower surface of the workbench 1; The support leg 11 helps to improve the overall stability.

[0021] A control console 12 is fixedly connected to one side of the front outer wall of the workbench 1. A PLC control panel 13 is embedded in the upper surface of the control console 12. The PLC control panel 13 is electrically connected to the servo motor 22 and the synchronous motor 31 respectively. The PLC control panel 13 is electrically connected to the servo motor 22 and the synchronous motor 31 respectively, which facilitates the control of their switching.

[0022] A pad 14 is fixedly connected to the middle of the upper surface of the workbench 1; The pad 14 facilitates cushioning when placing the display screen.

[0023] The slide rods 25 slide in opposite directions on the inner wall of the storage slot 21 respectively; The slide bars 25 slide in opposite directions on the inner wall of the storage slot 21, which facilitates clamping the two sides of the display screen.

[0024] The upper ends of the screws 27 all pass through the mounting grooves 26 to the upper part of the slide rods 25 and are all fixedly connected to knobs 28; The knob 28 facilitates the rotation of the screw 27.

[0025] The sliding frames 33 slide opposite each other on the inner wall of the placement groove 3; The sliding bracket 33 facilitates the clamping of the display screen from the front and back.

[0026] Working principle: First, the servo motor 22 and synchronous motor 31 are started via the PLC control panel 13 on the console 12. The servo motor 22 drives the bidirectional screw 23 to rotate. Since the slide rod 25 is threadedly connected to the bidirectional screw 23 and slidably connected to the guide rod 24, the slide rod 25 will slide in opposite directions in the storage slot 21, thereby driving the side clamping plate 211 to initially adjust the lateral spacing to adapt to the width of the OLED screen. If it is necessary to adapt to the thickness of the screen, turning the knob 28 can drive the screw 27 to rotate, causing the sliding sleeve 210, which is threadedly connected to the screw 27 and slidably connected to the guide rod 29, to move up and down, thereby finely adjusting the height of the side clamping plate 211. The synchronous motor 31 drives the bidirectional screw 32 to rotate. The sliding frame 33 slides in opposite directions in the placement slot 3 because it is threadedly connected to the bidirectional screw 32, driving the front clamping plate 34 to adjust the front and rear spacing to adapt to the length of the screen. Finally, the front clamping plate 34 and the side clamping plate 211 cooperate to clamp the screen.
