[0050] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] like Figures 1 to 12 As shown, the mobile phone case production line of the present invention is used to process the mobile phone case 100 and place the mobile phone case 100 in the groove on the blister tray 200. The mobile phone case production line includes a machine 10, a cooling device 20, a drilling device 30, a discharging device 40, a first conveying device 50, a second conveying device 60, and a tray loading device 70; the cooling device 20, the drilling device 30, the discharging device 40 and the tray loading device 70 are arranged in sequence and arranged on the machine 10; the first conveying device 50 is arranged on the machine 10, and the first conveying device 50 is used to realize the movement of the mobile phone case 100 between the cooling device 20, the drilling device 30 and the discharging device 40; the second conveying device 60 is arranged between the discharging device 40 and the tray loading device 70, and is used to move the mobile phone case 100 from the discharging device 40 to the tray loading device 70; the tray loading device 70 includes an empty tray station 71 and a tray loading station 72, and the empty tray station 71 and the tray loading station 72 are provided with a blister tray 200 for carrying the mobile phone case 100.

[0052] The above-mentioned mobile phone shell production line is directly connected to the side of the injection molding machine. The injection molding machine obtains the mobile phone shell 100 through injection molding, and the mobile phone shell 100 is placed in the cooling device 20 through the manipulator. The cooling device 20 cools the mobile phone shell 100, assists the molding of the mobile phone shell 100, improves the hardness of the mobile phone shell 100, and facilitates the subsequent drilling process. The first transport device 50 transports the cooled mobile phone shell 100 to the drilling device 30, and the drilling device 30 performs drilling processing on the mobile phone shell 100. The first transport device 50 transports the mobile phone shell 100 that has completed the drilling process to the discharging device 40 for discharging. The second conveying device 60 moves the empty blister tray 200 in the empty tray station 71 to the tray loading station 72, and then the second conveying device 60 moves the mobile phone case 100 in the discharge device 40 to the blister tray 200 in the tray loading station 72; this cycle is repeated until the number of fully loaded blister trays 200 reaches a preset number, and the system reminds the staff to move the fully loaded blister trays 200 to ship the mobile phone case 100.

[0053] See also Figures 1 to 3 The cooling device 20 includes a feeding and conveying module 21, a shell 22 disposed in the middle section of the feeding and conveying module 21, and a cooling fan 23 embedded in the top surface of the shell 22; the feeding and conveying module 21 drives the mobile phone shell 100 to enter the shell 22, and the cooling fan 23 cools the mobile phone shell 100. The mobile phone shell 100 obtained by injection molding will have insufficient material stability due to its high temperature, and thus the hardness cannot meet the subsequent drilling process. Therefore, the mobile phone shell 100 is placed on the feeding and conveying module 21, and the feeding and conveying module 21 drives the mobile phone shell 100 to move toward the drilling device 30; during the movement into the shell 22, the cooling wind of the cooling fan 23 cools the mobile phone shell 100, thereby increasing the hardness of the mobile phone shell 100 to meet the subsequent drilling process. It should be noted that in this embodiment, the feeding and conveying module 21 uses a motor to drive the transmission belt to rotate to achieve feeding and conveying.

[0054] See also Figures 4 to 8The drilling device 30 includes a Y-axis moving mechanism 31, an X-axis moving mechanism 32, a Z-axis moving mechanism 33, a drilling mechanism 34, and a waste recovery mechanism 35. The Y-axis moving mechanism 31 is provided with a processing table 311 which is driven and connected thereto, and the processing table 311 is provided with a dust cover 36. The waste recovery mechanism 35 is arranged at the bottom of the machine table 10 and is connected to the inner side of the dust cover 36; the X-axis moving mechanism 32 is arranged above the Y-axis moving mechanism 31, the Z-axis moving mechanism 33 is connected to the Y-axis moving mechanism 31, and the drilling mechanism 34 is connected to the Z-axis moving mechanism 33. The drilling mechanism 34 includes a processing spindle 341 and a sealing cover 342 disposed at the lower end of the processing spindle 341. Two processing spindles 341 are used, and two mobile phone shells 100 can be drilled at the same time to improve production efficiency; the Z-axis moving mechanism 33 drives the sealing cover 342 to move downward, driving the sealing cover 342 to cover the upper end opening of the dust cover 36, and the sealing cover 342 and the dust cover 36 form a sealed processing chamber; the processing end of the processing spindle 341 passes through the sealing cover 342 and extends into the sealed processing chamber to process the mobile phone shell 100. The drilling device 30 can automatically complete the drilling of the mobile phone shell 100 and prevent the generated dust from escaping, which is in line with the production concept of environmental protection and environmental protection. It should also be noted that the coverage area of ​​the sealing cover 342 is larger than the upper end opening of the dust cover 36. During the processing process, the sealing cover 342 and the dust cover 36 will move relative to each other, but the sealing cover 342 always covers the upper end opening of the dust cover 36 to ensure that the sealed processing chamber is in a closed state.

[0055] Specifically, the Y-axis moving mechanism 31 includes two first linear modules 312 arranged in parallel on the machine table 10, and the dust cover 36 and the processing table 311 are both installed on the first linear module 312; the first linear module 312 drives the dust cover 36 to move in the Y-axis direction. At the same time, the first linear module 312 is provided with an accordion cover on the outer cover, and the accordion cover is connected to the processing table 311 to protect the first linear module 312. Sensors are also provided on both sides of the processing table 311 for sensing the moving position of the processing table 311. In this embodiment, the first linear module 312 adopts a linear motor.

[0056] Specifically, the X-axis moving mechanism 32 includes a gantry 321 and a second linear module 322 disposed on the gantry 321, and the Z-axis moving mechanism 33 is mounted on the second linear module 322. The second linear module 322 is used to drive the Z-axis moving mechanism 33 and the drilling mechanism 34 to move along the X-axis; the second linear module 322 is provided with an accordion cover for protection. The Z-axis moving mechanism 33 includes a drivingly connected lifting module 331 and a lifting block 332; the lifting module 331 is mounted on the second linear module 322, and the drilling mechanism 34 is mounted on the lifting block 332. In this embodiment, the second linear module 322 and the lifting module 331 are both linear motors.

[0057] Specifically, the drilling mechanism 34 also includes a first connecting plate 343 and a second connecting plate 344; the first connecting plate 343 is vertically arranged and connected to one end of the Z-axis moving mechanism 33, and the machining spindle 341 is fixed to the side of the first connecting plate 343 away from the Z-axis moving mechanism 33; the second connecting plate 344 is horizontally arranged and fixedly connected to the bottom of the first connecting plate 343, and a connecting hole 3441 is opened at the corner of the second connecting plate 344; a floating pin 3421 is fixedly provided at the upper end of the sealing cover 342, and the floating pin 3421 is movably connected to the connecting hole 3441, and the sealing cover 342 can float up and down along the floating pin 3421 relative to the second connecting plate 344. Therefore, the sealing cover 342 has a certain floating space relative to the second connecting plate 344. On the one hand, it can avoid the hard contact between the sealing cover 342 and the dust cover 36, which may cause damage to the sealing cover 342. On the other hand, when the sealing cover 342 contacts the dust cover 36, the second connecting plate 344 and the processing spindle 341 can be further moved downward to ensure the normal progress of the punching process. In addition, a limiting cap is provided at the top of the floating pin 3421. The radius of the limiting cap is greater than the radius of the connecting hole 3441. The limiting cap is used to limit the floating pin 3421 to prevent the floating pin 3421 and the sealing cover 342 from being separated from the second connecting plate 344. Further, a plurality of air nozzles 3422 are provided on the sealing cover 342. The air nozzles 3422 are vertically arranged and penetrate the sealing cover 342. The air nozzles 3422 are connected to a hair dryer to clean the positioning points inside the dust cover 36 to ensure the accuracy of the subsequent punching process. In addition, the X-axis moving mechanism 32 and the Y-axis moving mechanism 31 are cooperated to sweep the air to further improve the cleaning effect.

[0058] Specifically, the waste recovery mechanism 35 includes a waste box 351 disposed at the bottom of the machine 10, a dust collecting pipe 352 connected to the waste box 351, a negative pressure generator 353 disposed on the dust collecting pipe 352, and a recovery funnel 354 disposed at the upper end of the dust collecting pipe 352; the upper end of the recovery funnel 354 is connected to the inner side of the dust cover 36. A waste hole is vertically connected to the bottom of the inner side of the dust cover 36 and the processing table 311, and the other end of the dust collecting pipe 352 is connected to the bottom of the processing table 311. The waste hole enables the dust collecting pipe 352 to communicate with the inner side of the dust cover 36. The recovery funnel 354 is disposed at the connection between the dust collecting pipe 352 and the processing table 311 to prevent dust from escaping and increase the amount of dust recovered. When working, the negative pressure generator 353 generates negative pressure, generates suction force toward the waste box 351, and the dust in the sealed processing chamber passes through the waste hole, the recovery funnel 354 and the dust collecting pipe 352 in sequence, and enters the waste box 351 to complete dust recovery. In addition, in this embodiment, the dust collecting pipe 352 adopts a large diameter, which can pass 85mm waste to avoid clogging.

[0059] Specifically, the side wall of the dust cover 36 is provided with a first air duct 361 and a second air duct 362, one end of the first air duct 361 and the second air duct 362 is connected to the inner side of the dust cover 36, and the other end of the first air duct 361 and the second air duct 362 is connected with a blowing and suction generator 363. The blowing and suction generators 363 of the first air duct 361 and the second air duct 362 switch working states regularly, that is, the first air duct 361 blows air, and the second air duct 362 sucks air; after a certain period of time, the first air duct 361 sucks air, and the second air duct 362 blows air, and the cycle works in this way, so that the dust in the sealed processing chamber flows and generates a vortex, thereby improving the dust removal effect. Further, the cross-sectional shape of the dust cover 36 is an ellipse, and the first air duct 361 and the second air duct 362 are symmetrically arranged. At the same time, the orientation of the first air duct 361 and the second air duct 362 is tangent to the side wall of the dust cover 36, avoiding the existence of internal dead angles, and further improving the dust removal effect. At the same time, a plurality of positioning posts 364 are provided at the bottom of the dust cover 36, and the positioning posts 364 are used to realize the fixed positioning of the mobile phone shell 100. This prevents the mobile phone shell 100 from loosening during the punching process, thereby affecting the punching and grooving accuracy.

[0061] See also Fig. 9 The first transport device 50 includes a third linear module 51 arranged transversely, a connecting frame 52 drivingly connected to the upper end of the third linear module 51, a first material picking module 53, and a second material picking module 54. The connecting frame 52 is Y-shaped. The first material picking module 53 and the second material picking module 54 are respectively installed at both ends of the connecting frame 52. The third linear module 51 drives the first material picking module 53 and the second material picking module 54 to move synchronously along the X axis.
