Description

Technical Field

[0001] The invention relates to the field of laser etching, and in particular to an etching and forming device for a mobile phone glass protective cover. Background Art

[0002] With the development of industrial automation and intelligent technology, the mobile phone manufacturing industry has higher and higher requirements for the automation and intelligence of production processes. The laser etching molding device can be combined with the automated production line to realize the automated processing of mobile phone glass protective covers, improve production efficiency and quality, and reduce labor costs.

[0003] However, when the existing etching forming device is used to position and clamp the mobile phone glass protective cover, the part where the clamp contacts the mobile phone glass protective cover may have problems such as high roughness and high hardness. During the clamping process, scratches are easily generated on the surface of the glass protective cover, affecting its appearance quality. At the same time, the mobile phone glass protective cover is usually fragile. If the clamping force of the clamp is too large, it is easy to cause the glass protective cover to be broken, broken, scratched, etc. In addition, excessive clamping force may also cause the glass protective cover to deform, affecting its flatness and dimensional accuracy, and thus affecting the quality of laser etching.

[0004] At the same time, if the structure of the fixture is not designed properly, it may block the laser irradiation path and affect the laser etching effect on the mobile phone glass cover. At this time, during the laser etching process, the clamping part of the fixture may block the laser from etching the edge of the glass cover, resulting in incomplete etching.

[0005] In addition, the existing fixture structure is complex, and the process of clamping and removing the mobile phone glass protective cover is cumbersome and takes a long time.

DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] refer to Figures 1 to 11 , a mobile phone glass protective cover etching and forming device, comprising an etching machine 1 and a tray 2 arranged inside the etching machine 1 and carrying a glass protective cover 3, and also comprising:

[0039] The flexible positioning mechanism 4 is connected to the tray 2, and includes a vacuum pump 9, a bearing platform 8, two cylinders 31, a plurality of suction cups 5 and a plurality of air release mechanisms 17. The bearing platform 8 is movably arranged below the tray 2. The two cylinders 31 are respectively arranged below the bearing platform 8 and the output ends are fixedly connected to the bearing platform 8. The vacuum pump 9 is arranged at the upper end of the bearing platform 8 and is fixedly connected to the bearing platform 8. The plurality of suction cups 5 are respectively slidably connected to the tray 2. The vacuum pump 9 drives the plurality of suction cups 5 to operate through the plurality of air release mechanisms 17.

[0040] A plurality of adjustable positioning mechanisms 34 are connected to the tray 2 , and each suction cup 5 has four adjustable positioning mechanisms 34 arranged in an array along the circumferential direction. The adjustable positioning mechanism 34 includes a rubber roller 35 , which is elastically arranged at the upper end of the tray 2 and abuts against the lower end of the glass protection cover 3 .

[0041] When the device is in operation, the operator places the glass protection cover 3 on the upper end of the corresponding suction cup 5 in turn, and the operator presses the glass protection cover 3 downward first. The glass protection cover 3 will be adsorbed by the suction cup 5 in the process of pushing the suction cup 5 downward. Before pressing, the operator first adjusts the distance between the plurality of rubber rollers 35 and the suction cup 5 according to the specifications of the glass protection cover 3 to ensure that the glass protection cover 3 can be positioned by the plurality of rubber rollers 35 around the suction cup 5 during the pressing process, thereby doubly positioning the glass protection cover 3 to prevent the glass protection cover 3 from moving during the etching process.

[0042] In order to elastically mount the rubber roller 35, the following features are also specifically provided:

[0043] The adjustable positioning mechanism 34 also includes a movable roller frame 36, a positioning roller frame 37, a synchronous plate 42, two side frames 40, two side blocks 41, two movable sliders 38 and four movable springs 39. The positioning roller frame 37 is fixedly connected to the tray 2, and the movable roller frame 36 is arranged on the side of the positioning roller frame 37 away from the suction cup 5 (refer to Figure 3 ), the two movable sliders 38 are respectively connected to the positioning roller frame 37 in a sliding manner (reference Figure 7 ), one end of the synchronous plate 42 is connected to the movable roller frame 36 in a horizontal sliding direction (reference Figure 8 ), the other end is fixedly connected to two movable sliders 38, two side frames 40 are respectively fixedly connected to the tray 2 and slidably connected to two side blocks 41, the two side blocks 41 are respectively slidably connected to the two sides of the movable roller frame 36, and the lower end of each movable slider 38 is respectively provided with two movable springs 39, the upper end of the movable spring 39 is fixedly connected to the movable slider 38, and the lower end is fixedly connected to the positioning roller frame 37, and the rubber roller 35 is rotatably connected to the upper end of the movable roller frame 36. When the lower end of the glass protection cover 3 abuts against the rubber roller 35, the glass protection cover 3 will continue to move downward and push the movable roller frame 36 to move downward. When the movable roller frame 36 moves, it will drive the two movable sliders 38 to move downward through the synchronous plate 42. When the movable slider 38 moves, it will drive the corresponding movable spring 39 to be compressed. The movable spring 39 is compressed so as to push the glass protection cover 3 to reset upward when it is reset later. At the same time, since the movable roller frame 36 has a vertical movable amount, when facing the glass protection cover 3 of different depths, the rubber roller 35 can better press the glass protection cover 3.

[0044] In order to achieve the horizontal pressing of the rubber roller 35 against the glass protection cover 3, the following features are also specifically provided:

[0045] The adjustable positioning mechanism 34 also includes a turntable 49, a main pulley 48, two synchronous wheels 47, four telescopic rods 46, two screw seats 45, two tightening springs 44 and two screws 43. The turntable 49 is slidably connected to the movable roller frame 36, and the two synchronous wheels 47 are symmetrically arranged on both sides of the turntable 49 and are rotatably connected to the movable roller frame 36 (refer to Fig. 9 ), the synchronous wheel 47 is connected to the main pulley 48 through a belt, the synchronous wheel 47 is coaxially fixedly connected to the screw rod 43, two screw seats 45 are respectively arranged on one side of the movable roller frame 36 close to the positioning roller frame 37, the screw seats 45 are threadedly connected to the screw rod 43, and two telescopic rods 46 are respectively arranged on both sides of each screw seat 45, one end of the telescopic rod 46 is fixedly connected to the screw seat 45, and the other end is fixedly connected to the movable slider 38, one end of the tightening spring 44 is fixedly connected to the screw seat 45, and the other end is fixedly connected to the movable slider 38. When the edge of the inner side of the glass protective cover 3 is pressed against the rubber roller 35, under the action of the tightening spring 44, the rubber roller 35 will be tightened with the edge of the inner wall of the glass protective cover 3, and the four rubber rollers 35 can elastically position the glass protective cover 3 from the inner side of the glass protective cover 3 after acting simultaneously, ensuring that when the etching machine 1 is etching the glass protective cover 3, there will be no clamps on the outer side of the glass protective cover 3 that interfere with the operation of the etching machine 1.

[0046] In order to adapt to glass protection covers 3 of different widths, the operator can drive the main pulley 48 to rotate by rotating the turntable 49. After the main pulley 48 rotates, it will drive the two screws 43 to rotate through the two synchronous wheels 47. The two screws 43 will change the compression amount of the clamping spring 44 through the two screw seats 45 (in this process, the telescopic rod 46 limits the movement of the screw seat 45), thereby changing the initial position of the rubber roller 35 in the horizontal direction, so as to facilitate the rubber roller 35 to tighten the glass protection covers 3 of different sizes.

[0047] In order to accurately measure the rotation amplitude of the turntable 49, the following features are specifically set:

[0048] The adjustable positioning mechanism 34 also includes an indicator plate 50 and a scale plate 51. The indicator plate 50 is coaxially fixed to the rotating plate 49 and is rotatably connected to the movable roller frame 36 (refer to Fig. 9 ), the scale plate 51 is coaxially arranged with the rotating disk 49 and is fixedly connected to the movable roller frame 36. When the rotating disk 49 rotates, the rotating disk 49 drives the indicating disk 50 to rotate, and the pointer on the indicating disk 50 will align with the index on the scale plate 51 to measure the rotation amplitude of the rotating disk 49, thereby ensuring that the initial amount of the rubber roller 35 is the same when etching the same batch of glass protection covers 3.

[0049] In order to enable the suction cup 5 to move in the vertical direction, the following features are also specifically provided:

[0050] The flexible positioning mechanism 4 further includes a plurality of lifting springs 6 and a plurality of bearing tubes 7. The plurality of bearing tubes 7 are fixedly connected to the tray 2 and are slidably connected coaxially with the suction cup 5. The plurality of lifting springs 6 are respectively coaxially arranged with the plurality of bearing tubes 7 (refer to Fig.11 ), the upper end of the lifting spring 6 is fixedly connected to the suction cup 5, and the lower end is fixedly connected to the supporting tube 7. When the glass protection cover 3 abuts against the suction cup 5 and pushes the suction cup 5 to move downward, the suction cup 5 moves along the axis direction of the supporting tube 7 and pushes the lifting spring 6 to be compressed.

[0051] In order to supplement the specific structure of the deflation mechanism 17, the following features are also specifically provided:

[0052] The deflation mechanism 17 includes a positioning frame 24, a main pressure plate 18, a main pressure rod 19, a main rack 20, a speed change gear 21, a reversing gear 22 and a secondary rack 23. The positioning frame 24 is fixedly arranged below the tray 2, and the main pressure plate 18 is fixedly connected to the lower end of the suction cup 5 (refer to Fig.11 ), the main pressure rod 19 is slidably connected to the lower end of the supporting tube 7 and the upper end is fixedly connected to the main pressure plate 18, the main rack 20 is fixedly connected to the main pressure rod 19, the speed change gear 21 is rotatably connected to the positioning frame 24 through the wheel seat, and the reversing gear 22 is coaxially fixedly connected to the speed change gear 21 and rotatably connected to the positioning frame 24 through the wheel seat (reference Fig.10 and Fig.11 ), the auxiliary rack 23 is meshed with the reversing gear 22 and is slidably connected with the positioning frame 24. When the suction cup 5 moves downward, the suction cup 5 drives the main pressure rod 19 to move through the main pressure plate 18, and when the main pressure rod 19 moves, it drives the speed change gear 21 to rotate through the main rack 20, and the speed change gear 21 drives the auxiliary rack 23 to move through the reversing gear 22.

[0053] In order to further supplement the specific structure of the deflation mechanism 17, the following features are also specifically provided:

[0054] The deflation mechanism 17 further includes a connecting frame 25 and a connecting plate 26. The connecting frame 25 is fixedly connected to the auxiliary rack 23 (refer to Fig.10 ), the connecting plate 26 is fixedly connected to one end of the connecting frame 25 and is slidably connected to the positioning frame 24, and a avoidance hole 27 is formed on the connecting plate 26. When the auxiliary rack 23 moves, the auxiliary rack 23 can drive the connecting plate 26 to move through the connecting frame 25.

[0055] In order to position the moved connection plate 26, the following features are also specifically provided:

[0056] The deflation mechanism 17 further includes a lifting tension spring 28, a lifting inclined block 29 and a reset pressure plate 30. The lifting inclined block 29 is slidably connected to the positioning frame 24 (refer to Fig.10), the reset plate 30 is fixedly connected to the lower end of the jacking inclined block 29, the jacking tension spring 28 is sleeved on the outside of the jacking inclined block 29, one end of the jacking tension spring 28 is fixedly connected to the positioning frame 24, and the other end is fixedly connected to the reset plate 30, the jacking inclined block 29 is connected to the connecting plate 26 through the inclined sliding, and the jacking inclined block 29 passes through the avoidance hole 27 to position the connecting plate 26 when the connecting plate 26 moves away from the suction cup 5. When the connecting plate 26 moves and pushes the jacking inclined block 29 to move, the jacking inclined block 29 will first move downward and push the fixed jacking tension spring 28 to be compressed, and then the jacking tension spring 28 will pull the jacking inclined block 29 to move upward and reset, at this time, the jacking inclined block 29 passes through the avoidance hole 27 upward and positions the connecting plate 26 to prevent the connecting plate 26 from retreating by itself.

[0057] In order to realize the release of the connection plate 26, the following features are also specifically provided:

[0058] The deflation mechanism 17 further includes a plurality of expansion plates 33 and two positioning platforms 32. The two positioning platforms 32 are symmetrically arranged on both sides of the support platform 8 and are slidably connected to the support platform 8 (refer to Figure 6 ), two positioning platforms 32 are fixedly connected to the lower end of the tray 2 (reference Figure 4 ), a plurality of expansion plates 33 are respectively connected to the bearing platform 8 and abut against the upper end of the corresponding reset plate 30 (refer to Figure 5 When it is necessary to drive the connection plate 26 to reset, the cylinder 31 is started and drives the bearing platform 8 to move. When the bearing platform 8 moves, it will be limited by the two positioning platforms 32 and drive several expansion plates 33 to move at the same time. After the expansion plate 33 moves, it will drive the corresponding reset pressure plate 30 to move away from the positioning frame 24. At this time, the lifting inclined block 29 and the connection plate 26 are separated, and the suction cup 5 returns to the initial position under the action of the lifting spring 6.

[0059] In order to realize vacuum adsorption of the glass protection cover 3 by the suction cup 5 when the suction cup 5 moves downward, the suction cup 5 will automatically deflate after the etching is completed, so as to accelerate the separation speed of the glass protection cover 3 and the suction cup 5, the following features are also specifically provided:

[0060] The deflation mechanism 17 further includes a transfer pipe 12, a deflation pipe 14, a transfer pipe 13, a first hose 11 and a second hose 16. The flexible positioning mechanism 4 further includes a main air pipe 10, which is coaxially connected to the output end of the vacuum pump 9 (refer to Figure 6 ), one end of the second hose 16 is connected to the support tube 7 (reference Fig.10), one end of the transfer pipe 12 is connected to the other end of the second hose 16, one end of the first hose 11 is connected to the main air pipe 10, and the other end is connected to the other end of the transfer pipe 12, the transfer pipe 13 is arranged at the upper end of the transfer pipe 12 and one end is connected to the middle of the transfer pipe 12, the exhaust pipe 14 is coaxially slidably connected to the transfer pipe 13, one end of the exhaust pipe 14 is connected to the transfer pipe 13, and the other end of the exhaust pipe 14 is fixedly connected to the connecting frame 25, and the exhaust pipe 14 is formed with a plurality of exhaust holes 15 in an array with equal angles along the circumferential direction (reference Fig.11 ). When the suction cup 5 moves downward, as can be seen from the foregoing, the connecting frame 25 drives the air leakage pipe 14 to move toward the direction close to the transfer pipe 13. When the air leakage holes 15 are blocked by the inner wall of the transfer pipe 13, the vacuum pump 9 is started and the vacuum pump 9 will sequentially extract the air in the support pipe 7 through the main air pipe 10, the first hose 11, the transfer pipe 12 and the second hose 16, so that a vacuum negative pressure is formed between the suction cup 5 and the glass protection cover 3.

[0061] After etching is completed, as the cylinder 31 starts, the suction cup 5 moves upward and resets under the action of the lifting spring 6. At this time, the connecting frame 25 drives the vent pipe 14 to move away from the transfer tube 13. After the vent hole 15 and the inner wall of the transfer tube 13 are separated, the sealed flow channel between the main air pipe 10, the first hose 11, the transfer tube 12 and the second hose 16 will be destroyed, and the gas flows along the transfer tube 12, the transfer tube 13 and the vent pipe 14 and finally escapes from several vent holes 15. At this time, the negative pressure environment between the suction cup 5 and the glass protection cover 3 is destroyed, which is convenient for the operator to remove the glass protection cover 3 from the tray 2.

[0062] The working principle of the device is that when the device is in operation, the operator places the glass protection cover 3 on the upper end of the corresponding suction cup 5 in turn. At this time, the operator first presses the glass protection cover 3 downward, and the glass protection cover 3 will be adsorbed with the suction cup 5 in the process of pushing the suction cup 5 downward. When the suction cup 5 moves downward, it can be seen from the foregoing that at this time, the connecting frame 25 drives the air release pipe 14 to move in the direction close to the main air pipe 10, and the connecting frame 25 will be positioned under the action of the lifting inclined block 29 to prevent the suction cup 5 from automatically resetting. When the suction cup 5 moves downward, the corresponding air release pipe 14 moves in the direction close to the transfer tube 13, and a number of air release holes 15 are blocked by the inner wall of the transfer tube 13. At this time, the vacuum pump 9 is started and the air in the support tube 7 is extracted through the main air pipe 10, the first hose 11, the transfer tube 12 and the second hose 16 in turn, so that a vacuum negative pressure is formed between the suction cup 5 and the glass protection cover 3.

[0063] After etching is completed, as the cylinder 31 starts, the connecting frame 25 and the lifting block 29 are separated, and the suction cup 5 moves upward and resets under the action of the lifting spring 6. At this time, the connecting frame 25 drives the vent pipe 14 to move away from the transfer tube 13. After the vent hole 15 and the inner wall of the transfer tube 13 are separated, the sealed flow channel between the main air pipe 10, the first hose 11, the transfer tube 12 and the second hose 16 will be destroyed, and the gas flows along the transfer tube 12, the transfer tube 13 and the vent pipe 14 and finally escapes from several vent holes 15. At this time, the negative pressure environment between the suction cup 5 and the glass protection cover 3 is destroyed, which is convenient for the operator to remove the glass protection cover 3 from the tray 2.

[0064] Before pressing, the operator first adjusts the distance between the plurality of rubber rollers 35 and the suction cup 5 according to the specifications of the glass protection cover 3.
