Description

Technical Field

[0001] The invention belongs to the technical field of glass polishing and relates to a glass cover plate edge polishing device. Background Art

[0002] Mobile phone glass cover products are mainly made of ultra-thin glass, which is produced through a series of special processing processes such as glass slicing, profiling, polishing, hardening, ultrasonic cleaning, vacuum coating, and silk screen printing. Since burrs will be generated on the edges of the glass cover during cutting, if they are not polished, they may cause gaps during the later assembly, affecting product quality. Therefore, mobile phone glass cover products need to be polished after production.

[0003] A search revealed a Chinese patent document that discloses an edge polishing device for glass cover production [Application Number: CN202020779675.1; Publication Number: CN212311709U]. This device includes a support base, a horizontal plate slidably mounted in the middle of the top of the support base, a mounting plate fixedly connected to the top of the support base, a support frame fixedly connected to the top of the support base, a vertical plate fixedly connected to the top of the horizontal plate near the mounting plate, and a horizontally mounted threaded sleeve fixedly mounted on the mounting plate. Although this device can polish all four sides of a glass cover, it requires the operator to repeatedly adjust the angle of the glass cover and reload the material, which is cumbersome and inefficient.

[0004] Based on this, we designed a glass cover edge polishing device. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a glass cover edge polishing device. The technical problem to be solved by the device is: how to achieve continuous polishing of the four sides of the glass cover and improve the polishing efficiency.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A glass cover plate edge polishing device includes a workbench, a vertically distributed conveyor belt is provided on the workbench, and a drive motor for driving the conveyor belt is provided below the workbench, extrusion frames are fixed to the upper and lower frames of the conveyor belt, and the extrusion frames are provided with grooves, a plurality of clamping mechanisms distributed at equal intervals are provided on the conveyor belt, a placement mechanism for loading materials is provided on the workbench, and the placement mechanism is located on one side of the conveyor belt, and four polishing mechanisms for polishing the edges of the glass cover plate and four rotating mechanisms for adjusting the direction of the glass cover plate are also provided on the workbench, and the polishing mechanisms and the rotating mechanisms are alternately distributed on the other side of the conveyor belt.

[0008] The working principle of the present invention is as follows: when in use, the conveyor belt is driven by a driving motor to run, and the conveyor belt drives several clamping mechanisms to move. The operator places the glass cover plate on the placement mechanism. When the clamping mechanism moves to the position of the placement mechanism, it clamps the glass cover plate placed above it, and then moves to the other side of the conveyor belt. At this time, the outer edge of the glass cover plate is polished by the closest polishing mechanism. After the polishing of this side is completed, the glass cover plate passes through one of the rotating mechanisms, and the rotating mechanism drives the glass cover plate to rotate 90°, and then the next polishing mechanism polishes it again. This is repeated to achieve polishing of all four sides of the glass cover plate. Then, when the glass cover plate rotates to the same side as the placement mechanism, another operator removes the glass cover plate.

[0009] The clamping mechanism includes two symmetrically distributed first slide rails fixed on the conveyor belt, a baffle is fixed at one end of the two first slide rails close to each other, a first magnetic strip is fixed to the bottom of the baffle, and a first sliding seat is slidingly arranged on the first slide rail, and a second magnetic strip is fixed to the side end of the first sliding seat, and the first magnetic strip and the second magnetic strip have the same magnetic poles relatively distributed, an extension rod is fixed on the first sliding seat, a fixed tube is fixed at the other end of the extension rod, and a rotating tube is rotatably arranged inside the fixed tube, and a round rod is fixed at the bottom of the rotating tube, a splint is fixed at one end of the round rod, the two splints are relatively distributed, and an anti-slip pad is fixed on the upper splint, and a suction cup pad is fixed on the lower splint, a number of suction cups are arranged on the suction cup pad, a limiting mechanism is provided inside the rotating tube, and a gear is fixed at the upper end of the rotating tube.

[0010] With the above structure, during use, when the first slide rail is located inside the groove, the repulsive force between the first magnetic strip and the second magnetic strip causes the two first sliding seats to separate from each other, and the conveyor belt drives the first slide rail to move. During the movement, when the first slide rail moves out of the groove, the side walls of the groove will squeeze the two first sliding seats toward the middle. At this time, the two clamping plates are driven close to each other by the extension rod, the fixed tube and the round rod to clamp the glass cover plate. After the glass cover plate is polished, the first slide rail follows the conveyor belt into the groove. At this time, the two first sliding seats separate, driving the two clamping plates to separate. At this time, the glass cover plate is adsorbed on the suction cup pad, and the operator can pull out the glass cover plate from the side.

[0011] A sliding hole is provided on the extension rod, and a lifting rod is slidably inserted into the sliding hole. A roller is rotatably provided on one end of the lifting rod close to the extrusion frame, and the roller is against the extrusion frame. The side end of the extension rod is threadedly connected with a hand bolt, and the end of the hand bolt is against the side end of the lifting rod.

[0012] With the above structure, the operator can adjust the position of the lifting rod by manually tightening the bolt, thereby adjusting the distance between the two clamping plates, thereby clamping glass cover plates of different thicknesses and expanding the application range of the device.

[0013] The limiting mechanism includes a lifting block slidably arranged inside the rotating tube, and a recess is provided inside the lifting block, a spring is provided in the rotating tube, and the two ends of the spring are respectively against the lifting block and the inner wall of the rotating tube, a square hole is provided at the side end of the rotating tube, a telescopic block is inserted into the square hole, and a fixed shaft is fixed on the telescopic block, two symmetrically distributed oblique slots are provided on the inside of the recess, and the two ends of the fixed shaft are respectively slidably arranged inside the oblique slots, four equally spaced limiting holes are provided on the fixed tube, and the telescopic block is inserted into one of the limiting holes, and the upper end edge of the lifting block is provided with a chamfer.

[0014] With the above structure, the telescopic block is inserted into one of the limiting holes, so that the rotating tube cannot rotate relative to the fixed tube, and further the clamping plate will not rotate when clamping the glass cover plate, thereby improving the stability of the glass cover plate during polishing. When the lifting block is squeezed downward, the cooperation between the inclined notch and the fixed shaft drives the telescopic block to retract inward. At this time, the rotating mechanism can drive the rotating tube to rotate, and after rotating 90°, the telescopic block and the lifting block are reset under the action of the spring. At this time, the telescopic block is inserted into another adjacent limiting hole, so that the glass cover plate remains stable during subsequent polishing.

[0015] The rotating mechanism includes two L-shaped plates fixed on the extrusion frame, and the two L-shaped plates are symmetrically distributed. Guide plates and racks are fixed on the outer sides of the L-shaped plates.

[0016] With the above structure, when in use, when the fixed tube moves to align with the guide plate, the guide plate squeezes the lifting block inward, and then the rack drives the gear to rotate, so that the rotating tube, round rod and clamping plate can be rotated 90 degrees synchronously, changing the direction of the glass cover.

[0017] The polishing mechanism includes a second slide rail fixed on the workbench, and a second sliding seat is slidably arranged on the second slide rail, a mounting frame is fixed to the upper end of the second sliding seat, a polishing and grinding head is rotatably arranged on the mounting frame, and a polishing motor for driving the polishing and grinding head to rotate is installed on the mounting frame, a vertical plate is fixed on the end of the second slide rail away from the conveyor belt, a laterally distributed push rod motor is fixed on the vertical plate, and the output shaft of the push rod motor is fixedly connected to the mounting frame.

[0018] With the above structure, the mounting frame can be driven by the push rod motor to move along the second slide rail, thereby changing the distance between the polishing and grinding head and the conveyor belt, so that the polishing and grinding head can be suitable for glass cover plates of different sizes and glass cover plates of the same size distributed in different directions, thereby expanding the scope of application of the device.

[0019] The placement mechanism includes a movable plate. A sliding assembly for driving the movable plate is provided on the workbench. A placement frame is detachably fixed to the upper end of the movable plate. A movable groove is provided on the placement frame, and one side of the movable groove is opened.

[0020] With the above structure, the operator can place the glass cover on the placement frame. When the clamping mechanism passes by, the two clamps are aligned and clamped from the upper and lower sides of the glass cover, and then move out from the opening direction of the movable groove. In addition, the operator can replace placement frames of different specifications according to glass cover plates of different sizes, ensuring the accurate placement position of the glass cover while expanding the applicability of the device.

[0021] The sliding assembly includes a fixed bar fixed on the workbench, a third slide rail is fixed on the side of the fixed bar away from the conveyor belt, a third sliding seat is fixed on the third slide rail, a movable plate is fixed on the third sliding seat, a handle is fixed on the side end of the movable plate, a cross plate is fixed on the other side of the movable plate, and a through hole is provided on the cross plate, a push plate is slidably inserted in the through hole, a slider is fixed on the side end of the push plate, an inclined slide groove is provided on the side of the fixed bar close to the conveyor belt, and the slider is slidably arranged in the inclined slide groove.

[0022] With the above structure, when the extension rod abuts against the push plate during movement, the clamping plate is aligned with the glass cover plate placed on the placement frame. At this time, the extension rod will drive the placement frame and the glass cover plate placed thereon to move synchronously through the push plate. The two clamping plates gradually clamp the glass cover plate during movement to prevent the glass cover plate from shaking when the clamping plates are in contact with the glass cover plate but not tightly abutted, thereby improving the accuracy of the glass cover plate position. Moreover, under the action of the inclined slide groove and the slider, the push plate gradually moves downward during movement and disengages from the extension rod, which will not hinder the movement of the extension rod. When placing the glass cover plate, the operator can use the handle to push the movable plate and the placement frame to reset and proceed to the next loading.

[0023] Compared with the existing technology, the glass cover edge polishing device has the following advantages:

[0024] 1. Through the conveyor belt, polishing mechanism, rotating mechanism and clamping mechanism, the operator can complete the grinding of the four sides of the glass cover plate by loading the material once, which reduces the labor intensity of the operator, saves loading time and improves grinding efficiency.

[0025] 2. Through the placement mechanism, the effect of precise loading is achieved, the accuracy of the clamping mechanism in clamping the glass cover is improved, the polishing quality of the glass cover is improved, and the loading operation of the operator is simplified, further reducing the labor intensity of the operator.

The specific principles will not be repeated here.

[0052] Working principle of the present invention:

[0053] When in use, the driving motor 3 drives the conveyor belt 2 to run, and the conveyor belt 2 drives the first slide rail 401 to move. The operator places the glass cover on the placement frame 804. When the extension rod 406 is moving and abuts against the push plate 808, the clamping plate 410 is aligned with the glass cover placed on the placement frame 804. At this time, the extension rod 406 will drive the placement frame 804 and the glass cover placed thereon to move synchronously through the push plate 808. At this time, the roller 416 gradually moves out of the groove 10 and drives the two first sliding seats 403 to be squeezed toward the middle. At this time, through the extension rod 406 and the fixed The tube 407 and the round rod 409 drive the two clamping plates 410 to approach each other to clamp the glass cover, and then move out from the opening direction of the movable groove 805. Under the action of the inclined slide groove 809 and the slider 810, the push plate 808 gradually moves down during the movement and breaks away from the extension rod 406 without hindering the movement of the extension rod 406. The glass cover follows the conveyor belt 2 and moves to the other side of the conveyor belt 2. At this time, the closest polishing head 704 rotates under the action of the polishing motor 705 and polishes one side of the glass cover. After the polishing of this side is completed, the glass cover continues to move. When the fixed When the tube 407 moves to align with the guide plate 603, the lifting block 501 is squeezed inwardly under the action of the guide plate 603, and the telescopic block 503 is driven to retract inwardly through the cooperation between the inclined notch 504 and the fixed shaft 505. The gear 411 is driven to rotate by the rack 602, so that the rotating tube 408, the round rod 409 and the clamping plate 410 can be rotated 90 degrees synchronously. After rotating 90 degrees, the telescopic block 503 and the lifting block 501 are reset under the action of the spring 506. At this time, the telescopic block 503 is inserted into another adjacent limiting hole 507, so that during subsequent polishing, the glass The glass cover plate is still stable, and then it is polished again by the next polishing mechanism 7. This process is repeated to polish all four sides of the glass cover plate. Then, when the glass cover plate rotates to the same side as the placement mechanism 8, the roller 416 gradually enters the groove 10. At this time, the repulsive force between the first magnetic strip 404 and the second magnetic strip 405 causes the two first sliding seats 403 to separate from each other. The separation of the two first sliding seats 403 drives the two clamping plates 410 to separate. At this time, the glass cover plate is adsorbed on the suction cup pad 413, and the operator can pull out the glass cover plate from the side to complete the edge polishing of the glass cover plate.

[0054] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
