Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone middle frame processing, in particular to a CNC precision rubber plug auxiliary processing structure for a mobile phone middle frame. Background Art

[0002] like Figure 1-Figure 5 As shown, in the existing CNC processing of the mobile phone middle frame, the mobile phone middle frame 3 needs to be clamped by the base 1 and the cover plate 2. Of course, to ensure that the clamping part inside the mobile phone middle frame is not damaged, a pressure-bonding layer 4 of a high-strength glue product is provided in the cover plate. After the mobile phone middle frame is clamped, a middle frame side hole 5 needs to be opened at the border of the mobile phone middle frame.

[0003] However, after some of the middle frame side holes are opened, a three-way structure is formed with the original internal channel 6 and external channel 7 inside the middle frame of the mobile phone. When the middle frame side holes are opened, the burrs flip back and forth in the three-way structure, making it difficult to identify; at the same time, the burrs flip into the dead corner of the channel, and the CNC dovetail knife cannot remove them. Manual removal is inefficient and the burr removal effect cannot be guaranteed. Utility Model Content

[0004] In order to solve the above technical problems, the utility model designs a CNC precision rubber plug auxiliary processing structure for a mobile phone middle frame.

[0005] The utility model adopts the following technical solutions:

[0006] A CNC precision rubber plug auxiliary processing structure for a mobile phone middle frame comprises a rubber plug body, wherein the rubber plug body comprises a rubber plug head, a supporting plug handle and a rubber plug fixing seat, wherein the rubber plug head and the rubber plug fixing seat are respectively fixedly connected to two ends of the supporting plug handle, wherein the two ends of the supporting plug handle are straight sections and the middle is an inclined section, the rubber plug head is flat and cooperates with an internal connection channel of the mobile phone middle frame, the upper and lower surfaces of the rubber plug fixing seat are horizontally and parallelly arranged, and the upper and lower surfaces of the rubber plug fixing seat are closely attached to the interior surface of the mobile phone middle frame and the surface of a pressing layer of a high-strength rubber product.

[0007] Preferably, both ends of the front section of the rubber plug are straight sections, and both ends of the rear section of the rubber plug are inwardly contracted inclined sections.

[0008] Preferably, the rubber plug fixing seat is L-shaped.

[0009] Preferably, a row of convex points are evenly installed on the front section of the rubber plug head. The convex points are used to assist in fixing the rubber plug. The rubber plug and the middle frame need to be closed at a position that is designed to be about 0.03mm to 0.05mm smaller, and the convex points are used to achieve zero matching.

[0010] Preferably, an observation notch is provided on the rear section of the rubber plug head, and the observation notch design facilitates identification of whether the installation is in place before processing.

[0011] Preferably, the rubber plug head, the supporting plug handle and the rubber plug fixing seat are integrally formed.

[0012] The beneficial effects of the utility model are as follows: the utility model designs a CNC precision rubber plug auxiliary processing structure for a mobile phone middle frame, which is simple to operate. It only needs to assemble the auxiliary rubber plug in the micro-slit channel structure of the product before CNC processing. After the rubber plug is assembled, the three-way structure is changed to a one-way structure, and the phenomenon of burrs turning outward to a dead angle structure is eliminated. The burr removal yield is high, and the burr ratio after CNC machine processing is reduced from 100% to 0.30%. The manual removal efficiency is high, and it is reduced from 300S to 30S per PCS middle frame. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0026] Example: Figure 6-Figure 11 As shown, a CNC precision rubber plug auxiliary processing structure for a mobile phone middle frame includes a rubber plug body 13, wherein the rubber plug body includes a rubber plug head 8, a supporting plug handle 9 and a rubber plug fixing seat 10, wherein the rubber plug head and the rubber plug fixing seat are respectively fixedly connected to two ends of the supporting plug handle, wherein the two ends of the supporting plug handle are straight sections and the middle is an inclined section, the rubber plug head is flat and cooperates with the internal connection channel of the mobile phone middle frame, the upper and lower surfaces of the rubber plug fixing seat are horizontally and parallelly arranged, and the upper and lower surfaces of the rubber plug fixing seat are closely attached to the interior surface of the mobile phone middle frame and the surface of the pressing layer of the high-strength rubber product.

[0027] The two ends of the front section of the rubber plug are straight sections, and the two ends of the rear section of the rubber plug are inwardly contracted inclined sections. The rubber plug fixing seat is L-shaped. A row of convex points 11 are evenly installed on the front section of the rubber plug.

[0028] The rear section of the rubber plug head is provided with an observation notch 12. The rubber plug head, the supporting plug handle and the rubber plug fixing seat are integrally formed.

[0029] When the utility model is used, the rubber plug product is placed in the middle frame body molding structure for interference fit, and the positioning cover plate is pressed on the tail of the rubber plug to offset the stress generated by the tool cutting during machine processing and prevent the gap from being generated by avoidance and retreat. After the machine processing is completed, the rubber plug is transferred to the dry ice deburring station, which can effectively prevent the burr from swinging back and forth. The dry ice deburring effect is improved, and the sporadic burrs are removed by using the dead angle structure of the rubber plug ejection before processing and the magnifying glass inspection, which can prevent the plastic burr from flanging defects. The rubber plug auxiliary tool uses plastic particle raw materials to be hot-melted by the injection molding machine and molded according to the size specifications.

[0030] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
