Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

As introduced in the background art, the cutter 2 in the prior art is in a straight rod shape, and when the periphery of the top and the periphery of the bottom of the mobile phone rear case 1 are processed, the cutter needs to be respectively clamped on different clamps for processing, so that not only much clamping time is needed, the processing efficiency is very low, but also the cost of the input clamps is very high. The processing of the two parts of the periphery of the top and the periphery of the bottom of the rear shell 1 of the mobile phone can be completed only by clamping once, and the processing is realized through the improvement of a cutter.

As shown in fig. 2, the cutter 15 of the invention can process the top and the bottom of the mobile phone rear shell 1, and can complete the processing of the periphery of the top and the periphery of the bottom of the mobile phone rear shell 1 by clamping the mobile phone rear shell 1 once, thereby reducing the three-damage defect caused by repeated assembly and disassembly, reducing the CNC processing time, improving the working efficiency, reducing the jig input amount, and saving the manpower and the clamp cost. Similar to the inventive tool 15, the inventive probe 16 can also probe the top and bottom of the handset back case 1, as shown in fig. 3.

With reference to fig. 5 and 7, fig. 5 is a schematic front view structure diagram of the cutter of the present invention for processing the periphery of the top of the mobile phone rear case, and fig. 7 is a schematic front view structure diagram of the cutter of the present invention for processing the periphery of the bottom of the mobile phone rear case; the inventive tool 15 includes a first connecting rod 151, a first bypass rod 152, and a knife edge 153. The first connecting rod 151 may connect the tool 15 to a tool driving member, and an external thread (not shown) may be provided on the top of the first connecting rod 151 to connect other members. The first escape bar 152 is connected to the bottom end of the first connecting bar 151, and the diameter of the first escape bar 152 is much smaller than that of the first connecting bar 151, so that the cutter 15 can escape from the circular arc protrusion 3 between the top and bottom of the back cover 1 of the mobile phone through the first escape bar 152, as shown in fig. 7.

The knife edge 153 directly contacts with the mobile phone rear case 1 and processes the mobile phone rear case 1, the knife edge 153 is connected to the bottom of the first escape bar 152, the knife edge 153 is formed by connecting two cones up and down, as shown in fig. 5, the upper cone is straight, and the lower cone is inverted, that is, the knife edge 153 includes a bottom processing knife face 1531 in an upright cone shape, the bottom processing knife face 1531 is used for processing the periphery of the bottom of the mobile phone rear case 1, as shown in fig. 7, the bottom processing knife face 1531 contacts with the bottom of the mobile phone rear case 1 for processing, the knife edge 153 further includes a top processing knife face 1532 in an inverted cone shape, the top processing knife face 1532 is used for processing the periphery of the top of the mobile phone rear case 1, as shown in fig. 5, the top processing knife face 1532 and the top. Therefore, the cutter 15 of the invention can process the periphery of the top and the periphery of the bottom of the mobile phone rear shell 1 without clamping the mobile phone rear shell 1 for many times, thereby improving the processing efficiency and saving the clamp cost.

Preferably, the first connecting rod 151, the first escape rod 152 and the knife edge 153 of the cutter 15 are integrally formed, and are formed by machining a straight metal rod with a relatively large diameter.

Fig. 6 is an enlarged view of a portion a of fig. 5 of the present invention, and as shown in fig. 6, it is understood that the bottom-machining blade face 1531 and the top-machining blade face 1532 are not completely tapered, and the tip portions thereof are in a cut plane similar to a shape in which the tip of a cone is cut off. Since the bottom machined surface 1531 has a top connected to the first bypass bar 152, it is preferable that the top is a circular surface having the same diameter as the first bypass bar 152 instead of a tip for securing the connection strength and facilitating the machining.

Referring to fig. 6, the inclination angles a of the bottom processing tool face 1531 and the top processing tool face 1532 are the same as the inclination angles b of the top periphery and the bottom periphery of the mobile phone rear case 1. Generally, the inclination angles b around the top and the bottom of the mobile phone rear case 1 are the same, and the inclination angles a of the bottom processing knife face 1531 and the top processing knife face 1532 are designed to be consistent with the inclination angles b around the top and the bottom of the mobile phone rear case 1, so that the knife edge and the processing face can be conveniently attached, and the processing precision is improved.

Referring to fig. 5, a first tapered connection part 1511 is disposed at a connection part of the first connecting rod 151 and the first avoidance rod 152, and the tapered connection part 1511 can avoid a problem that the first avoidance rod 152 is easily broken due to stress concentration caused by sudden size change of the connection part of the first connecting rod 151 and the first avoidance rod 152.

Fig. 4 is a schematic diagram of a reduced three-dimensional structure of the CNC probing and processing module for the back shell of the mobile phone of the present invention, and as shown in fig. 4, the CNC probing and processing module for the back shell of the mobile phone 10 of the present invention includes a frame 11, a workpiece table 12, a column 13, a beam 14 and a probe 16. The workpiece table 12 is arranged on the frame 11 and used for fixing the mobile phone rear shell 1. At least two upright posts 13 are arranged, the upright posts 13 are also arranged on the frame 11, and the upright posts 13 are positioned behind the workpiece table 12. The cross beam 14 is disposed on the top of the vertical columns 13, and as shown in fig. 4, two ends of the cross beam 14 are respectively connected to the tops of the two vertical columns 13.

The probe 16 and the cutter 15 are both provided on the beam 14, and the probe 16 and the cutter 15 are both movable in the X direction, the Y direction, and the Z direction to detect and process the rear case 1 of the mobile phone. When the CNC detection machining component 10 for the mobile phone rear shell works, the periphery of the top and the periphery of the bottom of the mobile phone rear shell 1 are detected through the probes 16 to see whether unqualified places exist or not, and then the unqualified places are machined through the cutter 15. The movement of the probe 16 and the cutter 15 can be realized by the cooperation of a motor and a screw rod, and many technical solutions for realizing X, Y, Z three-directional movement of the probe 16 and the cutter 15 exist in the prior art, and are not described herein again. It should be noted here that the movement of the probe 16 and the cutter 15 along the three directions X, Y, Z does not mean the movement of the probe 16 and the cutter 15 themselves, but the probe 16 and the cutter 15 can be moved by the movement of a connecting piece connected with the probe 16 and the cutter 15. The probe 16 and the tool 15 are moved, for example, by the movement of the beam 14.

Fig. 8 is a schematic side view of the probe of the present invention for probing the periphery of the top of the rear housing of a mobile phone, and as shown in fig. 8, the probe 16 has a structure similar to the tool 15, and includes a second connecting rod 161, a second escape rod 162, and a probe 163. The second connecting rod 161 is used to connect the probe 16 to the beam 14, and the tip of the second connecting rod 161 may be provided with an external thread connected to the beam 14, similar to the tool 15. The second avoidance rod 162 is arranged at the bottom end of the second connecting rod 161, and the second avoidance rod 162 is used for avoiding the mobile phone rear shell 1 when the probe detects the mobile phone rear shell 1. The diameter of the second bypass link 162 is much smaller than the diameter of the second connecting link 161.

The probe 163 is disposed at the bottom end of the second avoidance line 162, and similarly to the cutter 15, the probe 16 has a bottom surface detection surface 1631 with a forward tapered shape and a top surface detection surface 1632 with an inverted tapered shape, which are respectively used for detecting the periphery of the bottom and the periphery of the top of the mobile phone rear case 1.

Fig. 8 and fig. 10 respectively show that the probe 16 detects the periphery of the top of the mobile phone rear shell 1 through the top surface detection surface 1632, and the probe 16 detects the periphery of the bottom of the mobile phone rear shell 1 through the bottom surface detection surface 1631, and the avoidance function of the second avoidance rod 162 of the probe 16 on the mobile phone rear shell 1 can be clearly seen from fig. 10.

Preferably, the second link 161, the second escape bar 162, and the probe 163 are also integrally formed, and are formed by machining a single probe having a large diameter.

As shown in fig. 9, fig. 9 is an enlarged view of a portion B in fig. 8 of the present invention, and similar to the cutter 15, the inclination angles of the bottom surface detecting surface 1631 and the top surface detecting surface 1632 of the probe 16 are consistent with the inclination angles of the periphery of the top and the periphery of the bottom of the back shell 1 of the mobile phone, so that the detection is more accurate.

Referring to fig. 8, similar to the second tapered connecting portion 1511 of the tool 15, a second tapered connecting portion 1611 is disposed at a connecting portion between the second connecting rod 161 and the second bypass bar 162 of the probe 16 to avoid a problem that the second bypass bar 162 is easily broken due to stress concentration caused by a sudden change in size of the connecting portion between the second connecting rod 161 and the second bypass bar 162.

Referring to fig. 11 and 12, fig. 11 is a schematic perspective view of a workpiece table for the CNC probing and processing module for the rear shell of the mobile phone according to the present invention, and fig. 12 is a schematic exploded view of the workpiece table for the CNC probing and processing module for the rear shell of the mobile phone according to the present invention; the workpiece table 12 includes a base plate 121, a support block 122, a jig mounting plate 123, a jig base plate 124, a jig cover plate 125, and an electromagnet 126.
