Description

Technical Field

[0001] This invention belongs to the field of display screen processing technology, and in particular relates to a display screen positioning device for display screen processing. Background Technology

[0002] Display screens are used in all aspects of life and work, and are widely used in various electronic terminals such as mobile phones, computers, televisions, automotive display devices, industrial control panels, and medical instruments.

[0003] In the glass substrate processing of displays, the positioning operation before the cutting process is a crucial step to ensure processing accuracy. Traditional positioning devices mostly adopt a step-by-step approach of side positioning and top clamping. First, the substrate is aligned on the sides manually or by a simple mechanical structure, and then the pressing mechanism is activated separately to fix it at the top. These devices often use ordinary lead screw slide structures and lack self-locking functions. When subjected to external forces or equipment vibration, the positioning components are prone to displacement. At the same time, the step-by-step operation process increases positioning time, reduces overall processing efficiency, and the manual intervention is more likely to introduce human error, causing the glass substrate to shift or wobble before cutting, which in turn affects the subsequent cutting quality and causes defects such as chipped edges and dimensional deviations.

[0004] To address these issues, we provide a display screen positioning device for display screen processing. Summary of the Invention

[0005] The purpose of this invention is to provide a display screen positioning device for display screen processing. The positioning component employs a worm gear transmission structure, which can simultaneously drive side positioning and top clamping actions. When the lifting plate moves downward, the toothed plate drives the incomplete gear to rotate, causing the two side positioning plates to move towards each other, achieving precise side centering of the glass substrate. Simultaneously, the swing plate and the pressure plate press down synchronously, completing the stable clamping of the substrate top. The self-locking characteristic of the worm gear prevents the substrate from shifting or shaking before cutting. The synchronous operation design significantly shortens the positioning time, balancing positioning accuracy and processing efficiency, and solving most problems of existing traditional positioning devices. The process employs a step-by-step approach of side positioning and top clamping. First, the substrate is aligned on the sides manually or using a simple mechanical structure, and then the pressing mechanism is activated separately to fix it at the top. These devices often use ordinary screw and slide structures, which lack self-locking functionality. When subjected to external forces or equipment vibration, the positioning components are prone to displacement. At the same time, the step-by-step operation process increases positioning time, reduces overall processing efficiency, and the manual intervention is more likely to introduce human error, causing the glass substrate to shift or wobble before cutting. This, in turn, affects the subsequent cutting quality, resulting in defects such as chipped edges and dimensional deviations.

[0017] The present invention has the following beneficial effects: 1. The present invention adopts a worm gear transmission structure for the positioning component, which can synchronously drive the side positioning and top clamping actions. When the lifting plate moves down, the toothed plate drives the incomplete gear to rotate, causing the two side positioning plates to move towards each other, so as to achieve precise centering of the side of the glass substrate. At the same time, the swing plate and the pressure plate press down synchronously to complete the stable clamping of the top of the substrate. The self-locking characteristics of the worm gear can prevent the substrate from shifting or shaking before cutting. The synchronous operation design greatly shortens the positioning time and takes into account both positioning accuracy and processing efficiency.

[0018] 2. The power component of this invention adopts a design with a single motor and an electric push rod. By switching the displacement of the transmission rod, the conveying component and the positioning component are driven in a time-sharing manner. When the transmission rod moves to the point where the first locking rod engages with the first locking slot, power is transmitted to the conveying component, driving the conveyor belt to rotate; when it moves to the point where the second locking rod engages with the second locking slot, power is transmitted to the positioning component, driving the positioning action. This design eliminates the need for multiple independent motors, significantly reducing the energy consumption and hardware cost of the device. At the same time, the addition of the first and second springs ensures the stable engagement of the locking rod and the locking slot, preventing slippage during power transmission and improving the stability and integration of the device operation.

[0019] 3. This invention utilizes a cutting assembly to mount a laser cutting machine. Combined with a threaded rod transmission structure driven by a second motor, the laser cutting machine can smoothly slide along a second limiting groove. The guiding effect of the second limiting groove strictly ensures the straightness of the cutting path, avoiding cutting deviations. Compared to traditional mechanical cutting, laser cutting has a smaller heat-affected zone, effectively reducing defects such as chipping and scratches on the glass substrate, significantly improving the processing yield of display screen glass substrates. Simultaneously, this assembly, linked with a positioning assembly, can directly cut the positioned substrate, eliminating intermediate transfer steps and further ensuring cutting accuracy.

[0020] 4. In this invention, the transfer component combines mechanical transmission and electromagnetic clamping technology. During the cutting process, the hydraulic cylinder drives the clamp to move the cylindrical block downwards. With the help of the abutment rod and the path groove, the clamping plate accurately clamps one end of the glass substrate, providing stable support and preventing the substrate from deforming due to cutting force. After cutting, the electromagnet is de-energized and the clamping is released, and the cylindrical block resets and rotates, quickly transferring the cut substrate to the designated position. The entire process is uniformly coordinated and controlled by the PLC controller, requiring no manual intervention. This achieves automated operation of substrate support and transfer, significantly improving processing efficiency. At the same time, the combination of mechanical and electromagnetic clamping methods balances clamping stability and release flexibility, adapting to glass substrates of different specifications.

The positioning assembly 2 is fixedly connected to an L-shaped plate 212, and a first mounting plate 213 is fixedly connected to the end of the L-shaped plate 212. The positioning assembly 2 also includes second mounting plates 214 disposed on both sides of the first mounting plate 213. Positioning plates 215 are fixedly connected to the opposite sides of the two second mounting plates 214. Two arc-shaped grooves 216 are opened on the opposite sides of the two second mounting plates 214. A first hinge seat 217 is installed inside the two arc-shaped grooves 216. A first rotating rod 218 is symmetrically fixedly connected to one side of the first mounting plate 213. A first rotating plate 219 is rotatably connected to the outer wall of the first rotating rod 218. The adjacent first rotating plate 219 is connected to the lower first hinge seat 217.

At the same time, the downward movement of the first mounting base 224 pushes the first moving plate 231 along the second slide groove 229 of the second mounting base 228 through the first swing plate 232, and drives the pressure plate 234 downward through the second swing plate 233, completing the fixed clamping of the top of the glass substrate. The design of simultaneous side positioning and top clamping greatly improves positioning efficiency and accuracy, and avoids the substrate from shifting or shaking before cutting. The sliding cooperation between the slide rod 227 and the rectangular frame 226 further enhances the stability of the first mounting base 224 during the lifting process, ensuring that the entire positioning action is precise and controllable.

The electric push rod 324 can push the transmission rod 304 to slide along the first limiting groove 305 of the cylindrical tube 302. When the transmission rod 304 moves to the position where the first locking rod 309 is engaged with the first locking groove 310, the rotational force of the first sleeve 308 will be transmitted to the cylindrical tube 302 through the transmission rod 304, and then drive the conveying component 1 to rotate through the meshing of the second bevel gear 303 and the first bevel gear 107. This power switching method does not require additional settings. The single motor effectively reduces the energy consumption and cost of the device. When the electric push rod 324 pushes the transmission rod 304 to the position where the second locking rod 318 is engaged with the second locking slot 319, the rotational power is transmitted to the second sleeve 317, and drives the positioning component 2 through the second pulley 322, the belt and the first pulley 204. The setting of the first spring 312 and the second spring 321 can ensure the stable engagement of the locking rod and the locking slot, and avoid slippage during power transmission. At the same time, the design of a single motor in conjunction with the electric push rod 324 realizes the time-sharing drive of the two actions of conveying and positioning, which greatly improves the integration and operational stability of the device.

[0034] Example 4, please refer to Figure 1-14This fourth embodiment is an improvement on the first embodiment as follows: the cutting assembly 4 includes a second U-shaped plate 401 fixedly connected to the top of the base 101, a second motor 402 fixedly connected to an inner side of the second U-shaped plate 401, a threaded rod 403 fixedly connected to the output end of the second motor 402 and rotatably connected to the second U-shaped plate 401, a second moving plate 404 slidably engaged with the inner top of the second U-shaped plate 401 connected to the outer wall of the threaded rod 403, a second limiting groove 405 slidably engaged with the second moving plate 404 provided in the inner top of the second U-shaped plate 401, a first load-bearing plate 406 fixedly connected to the bottom of the second moving plate 404, and a laser cutting machine 407 fixedly connected to the bottom of the first load-bearing plate 406.

[0035] The operation process of this embodiment is as follows: The component uses the second U-shaped plate 401 fixed on the top of the base 101 as a mounting bracket. When the second motor 402 is running, it drives the threaded rod 403 to rotate, thereby driving the second moving plate 404, which is threaded to it, to slide smoothly along the second limiting groove 405 at the top of the second U-shaped plate 401. The second moving plate 404 drives the laser cutting machine 407 to move synchronously through the first load-bearing plate 406, thereby completing the precise cutting of the positioned glass substrate. The design of the second limiting groove 405 can prevent the second moving plate 404 from deviating when sliding, ensuring the straightness of the cutting path. Compared with traditional mechanical cutting, laser cutting can effectively reduce the chipping and scratches of the glass substrate and improve the processing yield of the display glass substrate.

[0036] Example 5, please refer to Figure 1-14 This fifth embodiment is an improvement on the first embodiment as follows: the transfer assembly 5 includes a hydraulic cylinder 501 fixedly connected to the top of the base 101, an extension plate 502 fixedly connected to the output end of the hydraulic cylinder 501, a caliper 503 fixedly connected to one side of the extension plate 502, the transfer assembly 5 also includes a first fixing plate 504 fixedly connected to the top of the base 101, a stop rod 505 fixedly connected to one side of the first fixing plate 504, the transfer assembly 5 also includes a guide rod 506 fixedly connected to the top of the base 101, a cylindrical block 507 slidably sleeved on the outer wall of the guide rod 506, a turntable 508 slidably sleeved on the guide rod 506 fixedly connected to the top of the cylindrical block 507, the turntable 508 engaging with the caliper 503, and a path groove 509 (the two ends of the path groove 509 are straight grooves, and the middle part is an arc groove) that slidably engages with the stop rod 505 on the outer wall of the cylindrical block 507.

[0037] A second load-bearing plate 510 is fixedly connected to the outer wall of the cylindrical block 507. The transfer assembly 5 also includes a connecting plate 511 set above the base 101. A first U-shaped seat 512 is fixedly connected to both sides of the connecting plate 511. A second U-shaped seat 513 is symmetrically fixedly connected to the bottom of the first U-shaped seat 512. An electromagnet 514 is fixedly connected to one end of the second U-shaped seat 513. A guide rod 515 is fixedly connected between the two inner sides of the second U-shaped seat 513. A movable seat 516 is slidably connected to the outer wall of the guide rod 515. A clamping plate 517 is connected to the movable seat 516 by a torque spring and attracted to the electromagnet 514. A third spring 518 is fixedly connected between the movable seat 516 and the second U-shaped seat 513. A PLC controller is set inside the control box 108. The PLC controller is electrically connected to the first motor 313, the second motor 402, and the electric push rod 324 by wires.

[0038] The operation process of this embodiment is as follows: the first mounting base 224 moves upward, driving the two positioning plates 215 to complete the side positioning of the glass substrate. At the same time, the pressure plate 234 moves downward to complete the fixed clamping of the glass substrate from above. During the process, the hydraulic cylinder 501 drives the extension plate 502 to drive the caliper 503 to move downward, thereby driving the cylindrical block 507 to move downward through the turntable 508. With the cooperation of the path groove 509 and the abutment rod 505, they rotate simultaneously, thereby causing the cylindrical block 507 to move towards the top of the glass substrate through the second load-bearing plate 510 and the four second U-shaped seats 513. When the abutment rod 505 moves along the straight groove on the path groove 509, the cylindrical block 507 can only move vertically downward. During this process, the four second U-shaped seats 513 move downward from the top of the glass substrate, so that the clamping plate 517 and the glass substrate are clamped together. The contact causes the clamping plate 517 to rotate towards the electromagnet 514. Once the clamping plate 517 passes the glass substrate, placing the glass substrate between the clamping plate 517 and the electromagnet 514, the electromagnet 514 is energized, attracting the clamping plate 517 upwards. This causes the clamping plate 517 to clamp the glass substrate to be cut, providing stable support at one end of the glass substrate and preventing deformation due to cutting force, thus improving cutting quality. After cutting, the hydraulic cylinder 501 is controlled to reset the cylindrical block 507, which in turn rotates the cut glass substrate away from the glass substrate to be cut via the second U-shaped seat 513. This quickly completes the transfer and handling of the cut glass substrate. This mechanical and electromagnetic clamping method ensures clamping stability and enables rapid release, significantly improving substrate transfer efficiency.
