Description

Technical Field

[0001] This utility model relates to the field of mobile phone glass bonding technology, and more specifically, it relates to a bonding device for mobile phone glass. Background Technology

[0002] In the field of mobile phone glass bonding equipment technology, existing technologies have several problems that urgently need to be solved. These problems seriously affect production efficiency and product quality, mainly in the following aspects:

[0003] First, existing mobile phone glass bonding equipment suffers from significant efficiency bottlenecks in practical applications. When bonding glass to the phone casing, the equipment heavily relies on manual calibration and positioning. Operators need to rely on experience and visual judgment to adjust the relative positions of the casing and glass. This manual alignment method is not only time-consuming and labor-intensive, but also frequently results in inaccurate positioning during actual operation. When a positional deviation is found, repeated manual fine-tuning is required. This repetitive adjustment work not only greatly reduces production efficiency, but more importantly, it is prone to positioning errors during the bonding process, leading to imperfect bonding between the glass and the casing, resulting in material waste and economic losses.

[0004] Secondly, although some improved equipment has introduced guiding devices and equipped them with negative pressure suction cup systems in an attempt to achieve stable clamping and fixing of mobile phone casings and glass through vacuum negative pressure, these devices still have obvious technical defects. The most prominent problem is that the negative pressure system adopts a fixed suction speed design and lacks a flexible adjustment mechanism. This rigid design cannot adjust the negative pressure suction speed according to the characteristics of different specifications of mobile phone glass and casings, as well as different process requirements. Consequently, it cannot effectively adjust the strength of the suction clamping. This limitation makes it difficult to optimize the clamping effect. When dealing with casings or glass of different materials or sizes, it cannot provide the most suitable clamping force, which may cause the suction to be too tight and damage the workpiece, or the suction force to be insufficient and cause the glass or casing to fall off.

[0005] More seriously, while some improved devices have added an airflow speed adjustment function, attempting to achieve dynamic adjustment of negative pressure intensity through the cooperation of mechanical components, these improved designs still have significant flaws. These adjustment devices are often too simple in structure and are prone to problems during actual use. On the one hand, the vibration generated during continuous operation of the equipment will cause continuous impact on the adjustment mechanism. On the other hand, the continuous impact of high-speed airflow will also have an adverse effect on the internal structural components. These factors together cause the adjustment structure to easily loosen or even undergo slight displacement. This structural instability directly affects the stability of the adjusted airflow speed, causing fluctuations in the clamping effect and making it impossible to maintain the optimal state continuously, which seriously affects the practicality and reliability of the bonding device.

The adjusting block 7 is slidably disposed in the adjusting groove 8, which is inclinedly formed inside the connecting pipe 4. The outer wall of the linkage sleeve 10 is connected via a threaded connection. The control sleeve 12 is movably connected to the inner wall of the connecting pipe 5. The control sleeve 12 is fixedly connected to the linkage sleeve 10 via the fixing rod 13. A limiting mechanism is provided on the outside of the connecting pipe 5. The limiting mechanism includes an arc groove 14, a round hole 15, a sliding sleeve 16, a movable plate 17, a mating rod 18, a movable spring 19, and a movable rod 20.

The sliding sleeve 16 is slidably sleeved on the outside of the connecting pipe 5. The movable plate 17 is rotatably sleeved on the outside of the connecting pipe 5. The mating rod 18 is fixedly connected to one end of the movable rod 20, and the movable rod 20 is fixedly connected to one side of the sliding sleeve 16. The movable spring 19 is sleeved on the outside of the movable rod 20 and the mating rod 18, and one end of the movable spring 19 is in contact with the movable plate 17.

[0034] The positioning device includes a guide platform 21, a lower pressing block 22 and an upper pressing block 23. The guide platform 21 is detachably installed inside the base 1 and the movable seat 2, respectively. The lower pressing block 22 is detachably installed inside the base 1 and the upper pressing block 23 is detachably installed in the movable seat 2.

[0035] The base 1 is detachably provided with a guide post 24, and the movable seat 2 is detachably provided with a guide sleeve 25, which is slidably sleeved on the outside of the guide post 24.

[0036] The top of the movable seat 2 is fixedly provided with a slide rod 26, and a push spring 27 is movably sleeved on the outside of the slide rod 26. The connecting seat 3 and the slide rod 26 are slidably connected.

[0037] Multiple suction cups 28 are detachably provided below the upper pressure block 23 and above the lower pressure block 22. A sealing strip 29 is provided on the outer side of one end of the connecting tube 4. A sleeve 30 is fixedly connected to one side of both the upper pressure block 23 and the lower pressure block 22. A sealing groove 31 is correspondingly opened on the inner side of the sleeve 30. The sealing strip 29 is usually made of rubber.

[0038] In this embodiment, when the device is needed, the housing is first placed above the base 1. Then, through the unique structural design of the guide platform 21, the housing enters the center of the guide platform 21, and the lower end face of the housing contacts the suction cup 28 connected to the top of the lower pressure block 22. Next, the glass is placed in the center of the upper guide platform 21, so that the guide platform 21 guides the glass. Then, the upper end face of the glass contacts the suction cup 28 connected to the lower part of the upper pressure block 23. Then, the two external suction devices are turned on respectively. Through the cooperation of the connecting pipe 5, the connecting pipe 4, and the sleeve 30, the suction cup 28 is drawn into a negative pressure state, so that the suction cup 28 below the upper pressure block 23 adsorbs the glass, and the suction cup 28 above the lower pressure block 22 adsorbs the housing. Then, the external hydraulic drive device at the top of the connecting seat 3 is turned on, so that the external hydraulic drive device drives the connecting seat 3 to descend. Then, the connecting seat 3 will drive the movable seat 2 to descend together. The movable seat 2 will then drive the guide sleeve 25 to slide down along the guide post 24. The cooperation between the guide post 24 and the guide sleeve 25 ensures the smooth sliding of the movable seat 2 and the connecting seat 3. Then, the lower end face of the guide platform 21 installed on the inner side of the movable seat 2 will contact the upper end face of the guide platform 21 installed on the inner side of the base 1. Then, the movable seat 2 and the guide sleeve 25 can no longer slide. Then, the connecting seat 3 slides along the slide rod 26 and squeezes the push spring 27. The connecting seat 3 will drive the upper pressure block 23 connected below and the adsorbed glass to descend, so that the glass is precisely attached to the upper shell of the adsorbed shell on the inner side of the base 1. Then, the external air extraction device is turned off, and then the external hydraulic drive device is reversed to reset the movable seat 2 and the connecting seat 3. The setting of the sealing strip 29 and the sealing groove 31 effectively ensures the sealing of the connection between the connecting pipe 4 and the sleeve 30 and prevents unstable adsorption.

[0039] Please see Figures 3-7 As a further embodiment of the overall equipment: a conical spring 32 is connected to one side of the adjusting block 7, and a conical block 33 is connected to the other end of the conical spring 32.

[0040] A movable block 34 is connected to one side of the adjusting block 7, and a movable groove 35 is correspondingly opened on one side of the linkage sleeve 10. The movable block 34 is slidably disposed in the movable groove 35.

[0041] Multiple locking rods 36 are slidably provided on the side wall of the adjusting sleeve 9, and multiple locking slots 37 are provided on the outer wall of the connecting pipe 5. The inner end of the locking rod 36 is inserted into the locking slot 37. A return spring 38 is provided on the outer side of the adjusting sleeve 9, and the outer end of the locking rod 36 is connected to the outer wall of the adjusting sleeve 9 through the return spring 38.

[0042] More specifically, when it is necessary to adjust the suction speed and intensity according to different batches of products, firstly, remove the two guide blocks 21 from the inside of the connecting seat 3 and the base 1 respectively. Then, remove the upper pressure block 23 from below the connecting seat 3, and then remove the lower pressure block 22 from the inside of the base 1. Then, replace them with guide blocks 21, upper pressure blocks 23, and lower pressure blocks 22 of the corresponding specifications. Then, install the upper pressure block 23 under the connecting seat 3, and make the sleeve 30 connected above the upper pressure block 23 fit onto the outside of the connecting pipe 4 connected to the connecting seat 3. Then, make the multiple sealing sleeves set on the outside of the connecting pipe 4 snap into the corresponding sealing grooves 31 opened on the inside of the sleeve 30. Then, install the lower pressure block 22 into the inside of the base 1 in the same way. Then, install the replaced guide blocks 21 respectively. Move the movable plate 17 to the inner side of the base 1 and the inner side of the movable seat 2. Then rotate the movable plate 17. The movable plate 17 will drive the arc groove 14 and the round hole 15 to rotate. When the round hole 15 moves to a position concentric with the mating rod 18, push the sliding sleeve 16. The sliding sleeve 16 will drive the mating rod 18 to slide into the round hole 15 through the movable rod 20. The sliding sleeve 16 will cooperate with the movable plate 17 to compress the movable spring 19. When the movable spring 19 is compressed to its limit, the mating rod 18 will completely pass through the round hole 15 and move to the other side of the movable plate 17. At this time, the movable rod 20 is in the round hole 15. Then rotate the movable plate 17 in the opposite direction. Then the arc groove 14 and the round hole 15 will follow the movable plate 17 to rotate in the opposite direction. Then the movable rod 20 will enter the arc groove 14. Then the mating rod 18 and the movable rod 20 When the sliding sleeve 16 is positioned to one side of the movable plate 17, the locking rod 36 loses its position. Then, the adjusting sleeve 9 rotates, causing multiple locking rods 36 slidably mounted on the side wall to move. The inner wall of the slot 37 then presses against the inner end of the locking rod 36. Due to the rounded corners at the end of the locking rod 36 and the edge of the slot 37, one end of the locking rod 36 slides out of the slot 37, and the other end of the locking rod 36 stretches the return spring 38. Simultaneously, the adjusting sleeve 9 moves the control rod 11 via the connecting rod 6. Due to the unique prismatic structure design of the control rod 11 and control sleeve 12, the control rod 11 rotates the control sleeve 12. The control sleeve 12 then rotates the linkage sleeve 10 via the outer fixing rod 13. The linkage sleeve 10 then moves along the screw thread set on the inner wall of the connecting pipe 5. As the ring rotates, the linkage sleeve 10 pushes the adjusting block 7 to slide along the adjusting groove 8. Due to the unique inclined structure of the adjusting groove 8, the adjusting block 7 moves inward as it slides. Then, the adjusting block 7 drives the movable block 34 to slide along the movable groove 35. At the same time, multiple conical blocks 33 gradually come together. Then, the adjusting block 7, in conjunction with the conical blocks 33, compresses the conical spring 32, causing the gap between the conical springs 32 to change. Combined with the movement of the adjusting block 7, this changes the water flow area inside the connecting pipe 5. Once a suitable flow rate is reached, the rotation of the adjusting sleeve 9 stops, and the return spring 38 drives the locking rod 36 to reset. This causes the other end of the locking rod 36 to slide into the corresponding locking groove 37. Then, the ring rotates forward again, causing the movable plate 17 to drive the round hole 15 and the arc groove 14 again.When the circular hole 15 moves back to the position concentric with the mating rod 18, the movable spring 19 pushes the sliding sleeve 16 to slide and reset. Then, the sliding sleeve 16 drives the mating rod 18 to slide and reset via the movable rod 20. After the movable spring 19 has fully reset, the movable plate 17 continues to rotate, causing the circular hole 15 and the arc groove 14 to rotate to a position that does not correspond to the mating rod 18 and the movable rod 20. At this time, the mating rod 18 and the movable rod 20 cooperate to support the sliding sleeve 16, preventing it from sliding. Then, the inner wall of the sliding sleeve 16 limits the outer end of the locking rod 36, preventing it from moving. Then, the locking rod 36 cooperates with the locking groove 37 to limit the adjusting sleeve 9, preventing it from moving easily. This ensures the structural stability after the flow rate adjustment and ensures the stable and reliable use of the equipment.

[0043] In summary, when using or operating the overall equipment: First, place the housing above the base 1. Then, through the unique structural design of the guide platform 21, the housing enters the center of the guide platform 21, and the lower end face of the housing contacts the suction cup 28 connected to the top of the lower pressure block 22. Next, place the glass into the center of the upper guide platform 21, allowing the guide platform 21 to guide the glass. Then, the upper end face of the glass contacts the suction cup 28 connected to the lower part of the upper pressure block 23. Next, activate the two external suction devices. Through the cooperation of the connecting pipe 5, the connecting pipe 4, and the sleeve 30, the suction cup 28 is drawn into a negative pressure state, causing the suction cup 28 below the upper pressure block 23 to hold the glass, and the suction cup 28 above the lower pressure block 22 to hold the housing. Finally, activate the external hydraulic drive device at the top of the connecting seat 3, causing the external hydraulic drive device to drive the connecting seat... 3 descends, and then the connecting seat 3 will drive the movable seat 2 to descend together. Then the movable seat 2 will drive the guide sleeve 25 to slide down along the guide post 24. The cooperation of the guide post 24 and the guide sleeve 25 ensures the smooth sliding of the movable seat 2 and the connecting seat 3. Then the lower end face of the guide platform 21 installed on the inner side of the movable seat 2 will contact the upper end face of the guide platform 21 installed on the inner side of the base 1. Then the movable seat 2 and the guide sleeve 25 can no longer slide. Then the connecting seat 3 slides along the slide rod 26 and squeezes the push spring 27. The connecting seat 3 will drive the upper pressure block 23 connected below and the adsorbed glass to descend, so that the glass is precisely attached to the upper shell of the adsorbed shell on the inner side of the base 1. Then the external air extraction equipment is turned off, and then the external hydraulic drive equipment is reversed to reset the movable seat 2 and the connecting seat 3. The setting of the sealing strip 29 and the sealing groove 31 effectively ensures the sealing of the connection between the connecting pipe 4 and the sleeve 30 and prevents unstable adsorption.

[0044] When it is necessary to adjust the suction speed and intensity according to different batches of products, firstly, remove the two guide blocks 21 from the inside of the connecting seat 3 and the base 1 respectively. Then, remove the upper pressure block 23 from below the connecting seat 3, and then remove the lower pressure block 22 from the inside of the base 1. Replace them with guide blocks 21, upper pressure blocks 23, and lower pressure blocks 22 of the corresponding specifications. Then, install the upper pressure block 23 under the connecting seat 3, and fit the sleeve 30 connected to the upper part of the upper pressure block 23 onto the outside of the connecting pipe 4 connected to the connecting seat 3. Then, make the multiple sealing sleeves set on the outside of the connecting pipe 4 snap into the corresponding sealing grooves 31 opened on the inside of the sleeve 30. Then, install the lower pressure block 22 into the inside of the base 1 in the same way. Finally, install the replaced guide blocks 21 onto the base. The inner side of the movable plate 17 and the inner side of the movable seat 2 are rotated. The movable plate 17 will drive the arc groove 14 and the round hole 15 to rotate. When the round hole 15 moves to a position concentric with the mating rod 18, it pushes the sliding sleeve 16. The sliding sleeve 16 will drive the mating rod 18 to slide into the round hole 15 through the movable rod 20. The sliding sleeve 16 will cooperate with the movable plate 17 to compress the movable spring 19. When the movable spring 19 is compressed to the limit, the mating rod 18 completely passes through the round hole 15 and moves to the other side of the movable plate 17. At this time, the movable rod 20 is in the round hole 15. Then, the movable plate 17 is rotated in the opposite direction. Then the arc groove 14 and the round hole 15 will follow the movable plate 17 to rotate in the opposite direction. Then the movable rod 20 will enter the arc groove 14. Then the mating rod 18 and the movable rod 20 will cooperate. The sliding sleeve 16 is positioned to one side of the movable plate 17, and then the locking rod 36 loses its position. The adjusting sleeve 9 is then rotated, causing multiple locking rods 36 slidably mounted on the side wall to move. The inner wall of the slot 37 then presses against the inner end of the locking rod 36. Due to the rounded corners at the end of the locking rod 36 and the edge of the slot 37, one end of the locking rod 36 slides out of the slot 37, and the other end of the locking rod 36 stretches the return spring 38. Simultaneously, the adjusting sleeve 9 moves the control rod 11 via the connecting rod 6. Due to the unique prismatic structure design of the control rod 11 and control sleeve 12, the control rod 11 rotates the control sleeve 12. The control sleeve 12 then rotates the linkage sleeve 10 via the outer fixing rod 13. The linkage sleeve 10 then moves along the threaded section on the inner wall of the connecting pipe 5. Rotation causes the linkage sleeve 10 to push the adjusting block 7 to slide along the adjusting groove 8. Due to the unique inclined structure of the adjusting groove 8, the adjusting block 7 moves inward as it slides. The adjusting block 7 then drives the movable block 34 to slide along the movable groove 35. Simultaneously, multiple conical blocks 33 gradually come together. The adjusting block 7, in conjunction with the conical blocks 33, compresses the conical spring 32, causing a change in the gap between the conical springs 32. This, combined with the movement of the adjusting block 7, changes the water flow area within the connecting pipe 5. Once a suitable flow rate is achieved, rotation of the adjusting sleeve 9 stops, causing the return spring 38 to reset the locking rod 36. The other end of the locking rod 36 then slides into the corresponding locking groove 37. Rotation then occurs again, causing the movable plate 17 to once again move the round hole 15 and the arc-shaped groove 14.When the circular hole 15 moves back to the position concentric with the mating rod 18, the movable spring 19 pushes the sliding sleeve 16 to slide and reset. Then, the sliding sleeve 16 drives the mating rod 18 to slide and reset via the movable rod 20. After the movable spring 19 has fully reset, the movable plate 17 continues to rotate, causing the circular hole 15 and the arc groove 14 to rotate to a position that does not correspond to the mating rod 18 and the movable rod 20. At this time, the mating rod 18 and the movable rod 20 cooperate to support the sliding sleeve 16, preventing it from sliding. Then, the inner wall of the sliding sleeve 16 limits the outer end of the locking rod 36, preventing it from moving. Then, the locking rod 36 cooperates with the locking groove 37 to limit the adjusting sleeve 9, preventing it from moving easily. This ensures the structural stability after the flow rate adjustment and ensures the stable and reliable use of the equipment.
