[0002] Mobile phones are an indispensable tool in people's daily lives. With the development of mobile phones, related equipment that matches mobile phones has also been strongly developed. A mobile phone charging box is a product that has the functions of protecting the safety of mobile phones and charging mobile phones. A mobile phone charging box is usually composed of a protective box and a charging head.

[0003] When producing mobile phone charging boxes, the produced charging heads and protective boxes are usually connected by glue. Since the gap at the connection position of the charging head and the protective box is relatively small, when applying glue, the glue needs to be injected into the tiny gap between the charging head and the protective box. The operation is laborious and the glue is easily applied to other positions of the charging head and the protective box, which affects the appearance of the mobile phone charging box and may affect the use of the mobile phone charging box, and also causes a waste of glue. Since there are usually bubbles in the glue, it is inevitable that the glue will be unevenly applied when applying the glue, resulting in a gap between the protective box and the charging head. Under the action of the bubbles in the glue and the gap between the protective box and the charging head, the bonding strength between the charging head and the protective box is relatively low.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In the present invention, the charging box body to be processed is installed in the support frame, and then the installation mechanism is started to insert the charging connector into the installation hole. When the charging connector is stably inserted into the installation hole, at this time, the driving slide bar drives the second sliding frame and the glue water tank to move to the bottom position inside the charging box body. When the glue water tank moves to the bottommost position inside the charging box body, at this time, start the glue injection mechanism to start injecting glue into the installation hole; through the glue injection mechanism, the glue can be automatically injected into the gap between the installation hole and the charging connector, and at the same time, when injecting the glue, the air and the gap part in the injected glue can be discharged. While ensuring the full utilization of the glue, the bonding strength between the charging connector and the charging box body can be effectively improved.

[0019] 2. When the second connecting frame moves towards the charging connector, the second connecting frame drives the two fixing rings inside it to move towards the charging connector through the second cylinder. When the two fixing rings move, they drive the first sealing plate towards the charging connector through the fixing rods on their surfaces. When all the sealing plates move to the position where they are in contact with the surface of the charging connector, the first motor can be stopped at this time, and then the first cylinder is started to drive all the sealing plates and the charging connector to move upward. When all the sealing plates move upward to the position where they are in contact with the charging box body, the first cylinder can be stopped at this time. Under the action of all the sealing plates, the bottom side part of the gap between the mounting hole and the charging connector can be sealed, so as to facilitate the injection mechanism to inject glue from the upper side position; when the injection mechanism finishes injecting glue and the glue solidifies, first start the cylinder on the upper side of the surface of the second connecting frame to drive the upper fixing ring to move downward. At this time, the upper fixing ring drives the corresponding first sealing plate to move downward away from the glue through the fixing rod on its surface, and then start the upper first cylinder to reset the separated first sealing plate. Then start the first cylinder on the lower side of the surface of the second connecting frame to drive the lower fixing ring to move downward. The lower fixing ring will drive the first sealing plate connected to it to move downward away from the glue. When the upper and lower fixing rings drive the first sealing plates to separate from the glue, the lower and upper fixing rings will drive the first sealing plates on their surfaces to press against the glue, so as to effectively prevent the first sealing plate from damaging the solidified glue when de-bonding.

[0032] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a precision machining device and a precision machining method for a mobile phone charging box, including a base plate 1, a first fixing frame 2 is fixedly connected to the upper surface of the base plate 1, a support frame 3 is fixedly connected to the surface of the first fixing frame 2, a charging box body 4 is arranged inside the support frame 3, an installation hole 5 is opened at the central position of the bottom of the charging box body 4, and a charging connector 6 is arranged at the position directly below the installation hole 5; a first cylinder 7 is fixedly connected to the middle position of the upper surface of the base plate 1, a first connecting frame 8 is fixedly connected to the upper end of the first cylinder 7, and an installation mechanism is arranged on the surface of the first connecting frame 8, and the installation mechanism is used to fix the charging connector 6 and insert it into the installation hole 5; a slide bar 9 is slidably connected to the middle position of the upper surface of the first fixing frame 2, a second fixing frame 10 is fixedly connected to the bottom end of the slide bar 9, a glue water tank 11 is arranged inside the second fixing frame 10, and a glue injection mechanism is arranged at the bottom of the glue water tank 11, and the glue injection mechanism is used to inject the glue in the glue water tank 11 into the gap between the charging connector 6 and the installation hole 5 and can eliminate the voids and bubbles in the injected glue during the glue injection process;

[0033] When working, mobile phones are an indispensable tool in people's daily lives. With the development of mobile phones, related equipment supporting mobile phones has also been strongly developed. A mobile phone charging box is a product that has the function of protecting the safety of mobile phones and charging mobile phones. A mobile phone charging box is usually composed of a protective box and a charging head. When producing mobile phone charging boxes, the produced charging head and the protective box are usually connected by glue. However, since the gap between the charging head and the protective box at the docking position is relatively small, when applying glue, the glue needs to be injected into the tiny gap between the charging head and the protective box. The operation is relatively laborious and it is easy to apply glue to other positions of the charging head and the protective box, which will affect the appearance of the mobile phone charging box and may affect the use of the mobile phone charging box, and will also cause a waste of glue. However, since there are usually bubbles in the glue, it is inevitable that the glue will be applied unevenly when applying the glue, resulting in a gap between the protective box and the charging head. The bubbles in the glue and the gap between the protective box and the charging head will cause the bonding strength between the charging head and the protective box to be low. The device is implemented by installing the charging box body 4 to be processed in the support frame 3, and then starting the installation mechanism to insert the charging connector 6 into the installation hole 5. When the charging connector 6 is stably inserted into the installation hole 5, the driving slide bar 9 drives the second sliding frame 30 and the glue box 11 to move to the bottom position of the charging box body 4. When the glue box 11 moves to the bottom position of the charging box body 4, the glue injection mechanism is started to start injecting glue into the installation hole 5. The glue injection mechanism can automatically inject glue into the gap between the installation hole 5 and the charging connector 6. At the same time, the air and the gap in the injected glue can be discharged during the injection of glue. While ensuring that the glue can be fully utilized, the bonding strength between the charging connector 6 and the charging box body 4 can also be effectively improved.

[0034] As a further solution of the present invention, the installation mechanism includes a motor 12. The motor 12 is fixedly connected to the first fixing frame 2 and the motor 12 is a double-shaft motor 12. Symmetrically fixed to the left and right ends of the output shaft of the motor 12 are first synchronous pulleys 13. A synchronous belt 14 is provided on the surface of the first synchronous pulleys 13. Symmetrically slidably connected to the left and right sides of the surface of the first connecting frame 8 are threaded rods 15. Fixedly connected to the positions of the left and right threaded rods 15 close to each other are second connecting frames 16. Inside the second connecting frames 16 are provided two fixing rings 17. Rotatably connected to the position of the first connecting frame 8 where it is connected to the threaded rod 15 is a second synchronous pulley 18. The second synchronous pulley 18 is in threaded cooperation with the threaded rod 15. The synchronous belt 14 is simultaneously engaged with the first synchronous pulley 13 and the second synchronous pulley 18. During operation, when the charging box body 4 is installed in the installation frame, at this time, the motor 12 is started. The motor 12 drives the first synchronous pulleys 13 on the left and right to rotate. The first synchronous pulleys 13 drive the second synchronous pulley 18 to rotate through the synchronous belt 14. When the second synchronous pulley 18 rotates, it will drive the threaded rods 15 on the surface of the first connecting frame 8 to slide relative to the first connecting frame 8. When the threaded rods 15 slide, they will drive the second connecting frames 16 to move. When the two fixing rings 17 inside the second connecting frames 16 on the left and right move to a position where they can clamp the charging connector 6, the motor 12 is stopped. Then, the first cylinder 7 is started to drive the first connecting frame 8 to move upward. The first connecting frame 8 will drive the clamped charging connector 6 to move upward into the installation hole 5 on the surface of the charging box body 4.

[0035] As a further solution of the present invention, a plurality of second cylinders 19 are fixedly connected to the upper and lower surfaces of the second connecting frame 16 in a uniform manner. The upper ends of the upper second cylinders 19 are fixedly connected to the upper fixing ring 17, and the bottom ends of the lower second cylinders 19 are fixedly connected to the lower fixing ring 17. A plurality of fixing rods 20 are fixedly connected to the upper surfaces of the upper and lower fixing rings 17. The upper and lower fixing rods 20 are alternately distributed, and the lower fixing rods 20 are slidably connected to the upper fixing ring 17. The upper ends of the upper and lower fixing rods 20 are located in the same plane, and the upper ends of the upper and lower fixing rods 20 are fixedly connected with a first sealing plate 21. Adjacent two first sealing plates 21 are in contact with each other, and all the sealing plates are in contact with the charging connector 6 and the charging box body 4. During operation, when the second connecting frame 16 moves towards the charging connector 6, at this time, the second connecting frame 16 will drive the two fixing rings 17 inside it to move towards the charging connector 6 through the second cylinders 19. When the two fixing rings 17 move, they will drive the first sealing plate 21 to move towards the charging connector 6 through the fixing rods 20 on their surfaces. When all the sealing plates move to the position where they are in contact with the surface of the charging connector 6, at this time, the first motor 12 can be stopped and then the first cylinder 7 is started to drive all the sealing plates and the charging connector 6 to move upward. When all the sealing plates move upward to the position where they are in contact with the charging box body 4, at this time, the first cylinder 7 can be stopped. Under the action of all the sealing plates, the bottom part of the gap between the mounting hole 5 and the charging connector 6 can be sealed, so as to facilitate the injection of glue by the glue injection mechanism from the upper position. When the glue injection mechanism completes the glue injection and the glue solidifies, first start the cylinder on the upper side of the second connecting frame 16 to drive the upper fixing ring 17 to move downward. At this time, the upper fixing ring 17 drives the corresponding first sealing plate 21 to move downward through the fixing rod 20 on its surface to separate from the glue, and then start the upper first cylinder 7 to reset the separated first sealing plate 21. Then start the first cylinder 7 on the lower side of the second connecting frame 16 to drive the lower fixing ring 17 to move downward. The lower fixing ring 17 will drive the first sealing plate 21 connected to it to move downward to separate from the glue. When the upper and lower fixing rings 17 drive the first sealing plate 21 to separate from the glue, the lower and upper fixing rings 17 will drive the first sealing plate 21 on their surfaces to press against the glue, so as to effectively prevent the first sealing plate 21 from damaging the solidified glue when de-bonding.

[0036] As a further solution of the present invention, the glue injection mechanism includes four delivery pumps 22. The four delivery pumps 22 are fixedly connected to the glue tank 11, and the bottom ends of the four delivery pumps 22 are fixedly connected with first glue injection pipes 23. Two connecting rods 24 are fixedly connected to the surface of the first glue injection pipes 23, and a connecting block 25 is fixedly connected to the bottom ends of the two connecting rods 24; at the bottom of the glue tank 11, there are a first connecting ring 26 and a second connecting ring 27. The first connecting ring 26 is in contact with the charging connector 6, and the second connecting ring 27 is in contact with the charging box body 4; the connecting block 25 is fixedly connected to both the first connecting ring 26 and the second connecting ring 27; between the first connecting ring 26 and the second connecting ring 27, there is a sliding ring 28. The width of the sliding ring 28 is equal to the distance between the charging connector 6 and the inner wall of the mounting hole 5, and the sliding ring 28 is slidably matched with the first connecting ring 26 and the second connecting ring 27; a second glue injection pipe 29 is slidably connected in the first glue injection pipe 23, and the bottom end of the second glue injection pipe 29 is fixedly connected to the sliding ring 28; during operation, when the bottom side part of the gap between the mounting hole 5 and the charging connector 6 is sealed, then the four delivery pumps 22 are started, and the glue in the glue tank 11 is transported into the first glue injection pipes 23 through the four delivery pumps 22. The glue in the first glue injection pipes 23 is discharged from the bottom position of the sliding ring 28 through the second glue injection pipe 29; at this time, the sliding ring 28 is located inside the gap between the mounting hole 5 and the charging connector 6, and as the glue is discharged from the bottom position of the sliding ring 28, the sliding ring 28 can be gradually pushed open.

[0037] As a further solution of the present invention, a sliding frame 30 is provided at the upper side position of the sliding ring 28. The sliding frame 30 is slidably connected to the connecting rod 24, and a stopper 31 is fixedly connected to the surface of the connecting rod 24 at the upper side position of the sliding frame 30; four telescopic tubes 32 are evenly and fixedly connected to the upper side surface of the sliding ring 28, and the upper ends of the four telescopic tubes 32 are fixedly connected to the glue tank 11; the second glue injection pipe 29 and the telescopic tubes 32 are both in clearance fit with the sliding frame 30; a first spring 33 is sleeved on the surface of the telescopic tube 32. The upper end of the first spring 33 is fixedly connected to the sliding frame 30, and the bottom end of the first spring 33 is fixedly connected to the sliding ring 28; during operation, when injecting glue into the mounting hole 5, as the glue is injected, the sliding ring 28 will be gradually pushed upward. At this time, the sliding ring 28 starts to compress the first spring 33 and move upward. Under the action of the first spring 33 and the self - weight of the sliding ring 28, the glue in the mounting hole 5 can be pressed evenly, and at the same time, the air in the glue and the air in the gap are pressed out. The pressed - out air and a small amount of glue will directly enter the glue tank 11 through the telescopic tubes 32, so that the air in the glue in the mounting hole 5 can be effectively removed, and the uniformity of glue application can be improved.

[0038] As a further solution of the present invention, two card slots 34 are provided on the surface of the second glue injection tube 29; two clamping blocks 35 are rotatably connected to the upper surface of the connection block 25 at positions corresponding to the two card slots 34 respectively. The two clamping blocks 35 are respectively engaged with the two card slots 34, and an elastic cord 36 is fixedly connected to the surface of the clamping block 35. The other end of the elastic cord 36 is fixedly connected to the connection block 25; a second sealing plate 37 is fixedly connected inside the first glue injection tube 23. The second sealing plate 37 is attached to the upper surface of the second glue injection tube 29, and the area of the second sealing plate 37 is larger than the cross-sectional area of the second glue injection tube 29; during operation, when glue is injected into the installation hole 5, at this time the glue will push the sliding frame 30 upwards, and the sliding frame 30 will continuously move upwards; when the installation hole 5 is filled with glue, at this time the sliding frame 30 moves upwards to the uppermost position, and the sliding frame 30 will drive the second glue injection tube 29 on its surface to move to the uppermost position; at this time, the card slot 34 on the surface of the second glue injection tube 29 just moves upwards to the position where it is engaged with the clamping block 35, and at the same time the upper surface of the second glue injection tube 29 just moves to the position where it is attached to the second sealing plate 37; the second glue injection tube 29 cannot move downwards under the action of the clamping block 35 and the card slot 34, so that the second glue injection tube 29 can be kept in a state of being attached to the second sealing plate 37. Under the action of the second sealing plate 37, the second glue injection tube 29 will automatically stop injecting glue.

[0039] As a further solution of the present invention, the second fixing frame 10 is slidably connected to the glue water tank 11, and a second spring 38 is fixedly connected to the middle position of the upper surface of the glue water tank 11. The upper end of the second spring 38 is fixedly connected to the second fixing frame 10; the second fixing frame 10 is fixedly connected to the sliding frame 30, and a pressing block 39 is fixedly connected to the bottom surface of the sliding frame 30 at a position above the clamping block 35; a driving block 40 is fixedly connected to the surface of the clamping block 35, and the driving block 40 is located at the bottom position of the pressing block 39; during operation, when it is necessary to inject glue into the installation hole 5, by pressing the sliding rod 9, the second fixing frame 10 can be driven to slide downwards relative to the glue water tank 11. The second sliding frame 30 starts to press the second spring 38 downwards at this time. When the second sliding frame 30 moves downwards, it drives the sliding frame 30 to move downwards. The sliding frame 30 will drive the pressing block 39 on its surface to move downwards. When the pressing block 39 moves downwards, it will start to press the driving block 40. By pressing the driving block 40, the pressing block 39 will drive the clamping block 35 to rotate. When the clamping block 35 rotates, it will disengage from the card slot 34. When the clamping block 35 disengages from the card slot 34, under the action of the first spring 33 and the self-weight of the sliding ring 28, the sliding ring 28 can slide into the installation hole 5, so that the second glue injection tube 29 starts to inject glue into the installation hole 5.

[0041] Step 1: First, install the charging box body 4 to be processed in the support frame 3, and then start the installation mechanism to insert the charging connector 6 into the installation hole 5;

[0042] Step 2: When the charging connector 6 is stably inserted into the installation hole 5, at this time, drive the sliding rod 9 to drive the second sliding frame 30 and the glue tank 11 to move towards the bottom position inside the charging box body 4;

[0043] Step 3: When the glue tank 11 moves to the bottommost position inside the charging box body 4, at this time, start the glue injection mechanism to inject glue into the installation hole 5;
