[0044] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0045] The double-sided processing device and CNC processing equipment according to the present invention will be described below with reference to the accompanying drawings.

[0046] like Figure 1 As shown, in an embodiment of the utility model, a double-sided processing device is proposed, which includes a flipping mechanism 1, a product fixing mechanism 2, a support block 3 and a moving mechanism 4. A processing opening 11 is provided on the flipping mechanism 1. The product fixing mechanism 2 is arranged on the flipping mechanism 1, and a avoidance opening 21 that is connected to the processing opening 11 is provided on the product fixing mechanism 2. The support block 3 is arranged on the moving mechanism 4, and the support block 3 and the moving mechanism 4 are both located below the flipping mechanism 1.

[0047] In the double-sided processing device of the utility model, the product is fixed on the flipping mechanism 1 by the product fixing mechanism 2, and both sides of the fixed product can be processed through the avoidance opening 21. The product fixing mechanism 2 can be flipped 360 degrees and stopped at any angle position by the flipping mechanism 1. Therefore, through the one-time positioning of the product fixing mechanism 2, both sides of the product can be processed in place, realizing one-stop processing of the front and back sides of the product. When the thickness of the product is relatively thin, the support block 3 is moved to the bottom of the product by the moving mechanism 4 and fits with the bottom surface of the product, which can support the product firmly, avoid the tool from acting on the product to cause deformation of the product, and thus avoid the problem of excessive tool cutting or milling causing product scrapping, thereby improving the processing quality of double-sided one-stop processing of thinner products.

[0048] It should be noted that the present application is aimed at CNC processing of metal parts for electronic products, which involves many processing features and small size, and has high requirements for processing quality. For thin metal parts for electronic products, by setting up a product auxiliary support structure composed of a support block 3 and a moving mechanism 4, one-stop full-area processing of the front and back sides of the thin product is achieved, ensuring processing accuracy and processing quality.

[0049] Specifically, the metal parts used in electronic products are the middle frame of the mobile phone. The middle frame of the mobile phone is an important part of the structure of the mobile phone. It is the connecting part between the screen and the back cover of the mobile phone. Its size and geometry can have a direct impact on the structural strength and quality of the mobile phone. The middle frame of the mobile phone is divided into TP surface and BP surface. The TP surface is the side where the screen is installed, and the BP surface is the side where the battery is installed. A middle plate is provided in the middle of the mobile phone middle frame, and the thickness is generally about 0.5mm. The process edge existing on the edges of the mobile phone middle frame before processing is completed is called a skirt. When the TP surface of the mobile phone middle frame is processed, most of the thickness of the middle plate is 2mm or more, and it can be supported without the auxiliary support structure of the product. However, when the mobile phone middle frame is turned 180 degrees to process the BP surface of the mobile phone middle frame, the area thickness of the middle plate is within 0.5mm. If auxiliary support is not used, the milling cutter will penetrate the middle plate or cause the middle plate to be over-milled, which will directly cause the product to be scrapped.

[0050] Among them, the CNC tool milling process is performed by the side edge and bottom edge of the milling cutter. During milling, the side and bottom surfaces of the mobile phone middle frame and its middle plate will be subjected to cutting forces of different sizes. When the thickness of the middle plate in the mobile phone middle frame is within 0.5mm, the cutting force that the mobile phone middle frame can withstand is very small, about 0.1kg to 0.2kg. Therefore, a support block 3 and a vacuum adsorption part must be set at the bottom of the middle plate to support the mobile phone middle frame to avoid over-milling or milling through. In addition, when the milling cutter is milling, the mobile phone middle frame and its middle plate will vibrate. If they are not firmly fixed, the mobile phone middle frame will be over-milled or milled through.

[0051] like Figure 1 As shown, when processing the mobile phone middle frame, first fix the mobile phone middle frame through the product fixing mechanism 2. At this time, the TP surface of the mobile phone middle frame faces upward, and the TP surface of the mobile phone middle frame can be processed. The TP surface of the mobile phone middle frame is processed first, and then the mobile phone middle frame is flipped through the flipping mechanism 1 after the processing is completed. At this time, the BP surface of the mobile phone middle frame faces upward, and the BP surface of the mobile phone middle frame can be processed. At this time, the support block 3 is moved to the bottom of the mobile phone middle frame through the moving mechanism 4, so that the support block 3 abuts against the TP surface of the mobile phone middle frame through the avoidance opening 21. The support block 3 can support the mobile phone middle frame. At this time, the BP surface of the mobile phone middle frame is processed again, which is not easy to damage the mobile phone middle frame. The double-sided processing device of the utility model drives the mobile phone middle frame to flip through the flipping mechanism 1 to achieve double-sided adjustment of the mobile phone middle frame, so that the mobile phone middle frame can be processed on both the TP surface and the BP surface at one time without clamping and moving. When processing the BP surface, the product fixing mechanism 2 is located below the flipping mechanism 1 and presses the mobile phone middle frame. At this time, the TP surface is below the flipping mechanism 1. The support block 3 is supported against the TP surface of the mobile phone middle frame through the moving mechanism 4, so that when the thickness of the mobile phone middle frame is too thin, the BP surface can still be processed without damaging the mobile phone middle frame.

[0052] The double-sided processing device of the utility model combines the BP surface and TP surface processing steps of the mobile phone middle frame. Through one-stop processing, the mobile phone middle frame is positioned and clamped once, and the BP surface and TP surface of the mobile phone middle frame are processed at one time, which can effectively improve the accuracy of the relative position of the BP surface and TP surface of the mobile phone middle frame. In the one-stop processing process, compared with the double-sided processing of the mobile phone middle frame in steps in the prior art, it can save the clamping time of the mobile phone middle frame once and the turnover time of the mobile phone middle frame once, and the efficiency of the one-stop processing is improved by 5%, and it can reduce the product collision scratches and repeated positioning errors caused by the clamping and turnover of the mobile phone middle frame, so that the yield of the mobile phone middle frame is improved by about 10%.

[0053] like Figure 2 As shown, the flip mechanism 1 includes a long bottom plate, two raised blocks arranged on the long bottom plate at intervals along the left-right direction, and the flip table 13, the raised blocks, and the long bottom plate enclose an installation space for the mobile mechanism 4 to be placed. The installation space is set to a height that the flip mechanism 1 will not interfere with the unadjusted support blocks when flipping. The mobile mechanism 4 is detachably arranged on the long bottom plate, using a modular splicing method. When the thickness of the processed mobile phone middle frame is between 0.5mm and 2.0mm, the mobile mechanism 4 can be installed to support the support block 3 to cooperate with the processing of the mobile phone middle frame; when the thickness of the processed mobile phone middle frame is 2.0mm or more, the mobile mechanism 4 can be removed. Furthermore, the specific disassembly and assembly of the mobile mechanism 4 needs to be determined according to the structure and area size of the mobile phone middle frame.

[0054] Among them, the flip mechanism 1 is also provided with four axes, a four-axis tailstock and an L-shaped connecting plate. A four-axis tailstock is provided on the top of each pad block. The opposite surfaces of the two four-axis tailstocks are formed with flange end faces. There are two L-shaped connecting plates, which are respectively installed on the four axes and the flange end faces of the four-axis tailstock. The four axes are arranged on the four-axis tailstock. The four axes are driven by a motor arranged inside the four axes to rotate by themselves, so as to drive the L-shaped connecting plate to rotate. The flip mechanism 1 has a simple structure and high working efficiency. It can conveniently adjust the flip table. The flip table is connected to both L-shaped connecting plates. The L-shaped connecting plate is used to fix the flip table. The flip table is fixed at the same time by multiple components, so as to improve the connection stability between the flip table and the L-shaped connecting plate.

[0055] like Figure 3As shown, in an embodiment of the utility model, the mobile mechanism 4 includes a Y-direction sliding component 41 and a lifting component 42. The lifting component 42 is connected to the Y-direction sliding component 41, and the support block 3 is arranged on the top of the lifting component 42. The front and rear adjustment and the up and down adjustment of the support block 3 are realized by the cooperation of the lifting component 42 and the Y-direction sliding component 41, and the multi-directional adjustment of the support block 3 can be realized, which can ensure the precise support of the mobile phone middle frame by the support block 3. It should be noted that the X direction is the left and right direction in the accompanying drawings, the Y direction is the front and back direction in the accompanying drawings, and the Z direction is the up and down direction in the accompanying drawings. The Y-direction sliding component 41 is located at the bottom of the mobile mechanism 4, and the lifting component 42 is installed on the top of the Y-direction sliding component 41. The support block 3, the lifting component 42 and the Y-direction sliding component 41 are arranged in sequence from top to bottom, which can make full use of the installation space below the mobile mechanism 4 and improve the overall structural compactness of the double-sided processing device. The Y-axis sliding assembly 41 can drive the entire lifting assembly 42 to move in the front-to-back direction as a whole, and the support block 3 located on the top of the lifting assembly 42 can move in the up-and-down direction along with the lifting assembly 42. When lifting is required, the lifting assembly 42 can drive the support block 3 to move up and down relative to the middle frame of the mobile phone, and the height of the support block 3 can be conveniently adjusted so that the support block 3 is in contact with the middle frame of the mobile phone, ensuring that the middle frame of the mobile phone is not easily damaged during processing.

[0056] like Figure 3 As shown, in an embodiment of the utility model, the Y-direction sliding assembly 41 includes a Y-direction base plate 411, a slide 412, a first cylinder and a first guide 413. The first guide 413 is arranged on the Y-direction base plate 411 along the Y-direction, the slide 412 is arranged on the first guide 413, the first cylinder is connected to and drives the slide 412 to slide in the Y-direction, and the lifting assembly 42 is arranged on the slide 412.

[0057] Among them, the top cover of the first guide member 413 is provided with a Y-direction protective cover 414, which is connected to the slide 412 and is used to prevent debris from entering the first cylinder and the first guide member 413, so as to prevent debris from interfering with the Y-direction sliding of the slide 412. When the slide 412 slides along the first guide member 413, the Y-direction protective cover 414 also moves together. Furthermore, the guide limit strip 416 is provided on the Y-direction bottom plate 411 along the front-back direction and is used to guide the Y-direction protective cover 414. The ends of the guide limit strip 416 along the Y-direction direction are provided with limit parts for limiting the position of the Y-direction protective cover 414 to prevent the Y-direction protective cover 414 from sliding out of the Y-direction bottom plate 411.

[0058] In addition, the Y-direction bottom plate 411 is also connected to an X-direction short plate, on which a second cylinder 431 is provided, and an X-direction protective cover 432 for preventing debris from falling onto the support block 3 is installed on the second cylinder 431. When the support block 3 is in the initial position, the X-direction protective cover 432 is provided above the support block 3. Preferably, a baffle 415 for preventing debris from entering the support block 3 from the left and right directions is also provided on the Y-direction bottom plate 411. It should be noted that the X-direction protective cover 432 is not limited to being adjusted by the second cylinder 431 to protect the support block 3, and other structural forms that can be adjusted and effectively protect the support block 3 can also be adopted.

[0059] like Figure 3 As shown, in the embodiment of the utility model, the lifting assembly 42 includes a carrier plate 423 arranged on the slide 412, a lifting cylinder 422 arranged on the carrier plate 423, and a second guide 421, the second guide 421 is arranged on the carrier plate 423 along the Z direction, the lifting cylinder 422 is connected to and drives the support block 3 to perform Z-direction lifting, the second guide 421 is a guide column, and a guide sleeve is provided at the bottom of the support block 3, and the guide sleeve cooperates with the guide column to ensure that the support block 3 is absolutely vertically lifted. It should be noted that the first cylinder, the second cylinder 431 and the lifting cylinder 422 of the present application all adopt the slide cylinder in the prior art, but can also be set to other devices that can realize the sliding adjustment of the support block 3.

[0060] like Figure 3 As shown, in an embodiment of the utility model, a fitting portion and a height-limiting column 31 are provided on the top of the support block 3, and a plurality of height-limiting columns 31 are arranged around the fitting portion, and the height-limiting columns 31 are lower than the fitting portion. The fitting portion of the support block 3 is located at the top of the support block 3 and is used to fit with the bottom surface of the mobile phone middle frame, and can stably support the mobile phone middle frame. There are 6 height-limiting columns 31 and they are arranged circumferentially along the fitting portion. The height-limiting columns 31 are used to support the skirt of the TP surface of the product to ensure that the fitting portion of the support block 3 fits exactly with the middle plate of the TP surface of the product, so as to avoid the milling cutter penetrating the middle plate or over-milling the middle plate during processing, resulting in the scrapping of the product. Of course, the number of height-limiting columns 31 can be set according to actual needs.

[0061] In an embodiment of the utility model, a support block positioning column 32 is further provided around the fitting portion, a support block positioning hole is provided on the product fixing mechanism, the support block positioning column 32 is adapted to the support block positioning hole, and the support block positioning column 32 is used to ensure the accuracy of the relative position of the support block 3 and the middle frame of the mobile phone.

[0062] When the TP surface of the mobile phone middle frame is processed, the flip mechanism 1 flips the mobile phone middle frame so that the BP surface of the mobile phone middle frame faces upward. At this time, the second cylinder 431 is used to drive the X-direction protective cover 432 to move to the left, so that the X-direction protective cover 432 is in an open state, and the support block 3 slides forward along the first guide member 413 under the drive of the first cylinder. When the support block 3 is aligned with the avoidance opening 21, the lifting cylinder 422 drives the support block 3 to move upward until the top surface of the support block 3 is just in contact with the middle plate surface of the TP surface of the mobile phone middle frame, and vacuum adsorption is turned on through the CNC program to suck the mobile phone middle frame tightly, and the height limit column 31 on the top surface of the support block 3 supports the TP surface skirt of the mobile phone middle frame to ensure that the support block 3 and the top surface of the support block 3 are just in contact with the TP surface of the mobile phone middle frame to prevent the mobile phone middle frame from moving. Then, the BP surface of the mobile phone middle frame is processed. When the BP surface processing is completed, the CNC program turns off the vacuum adsorption, and the lifting cylinder 422 drives the support block 3 to move downward. At the same time, the first cylinder drives the support block 3 to slide backward along the first guide member 413 to the initial position. The X-axis protective cover 432 is set above the support block 3, and the flipping mechanism 1 flips the mobile phone middle frame so that the TP surface of the mobile phone middle frame faces upward.

[0063] like Figure 2 and Figure 3 As shown, in the embodiment of the utility model, the product fixing mechanism 2 includes a cover plate 22 and a supporting block 23 which are arranged opposite to each other, and a product positioning member 231 is arranged on the side of the supporting block 23 facing the cover plate 22, and a plurality of product positioning members 231 are arranged circumferentially along the processing opening 11, and a plurality of plug interfaces are correspondingly provided on the mobile phone middle frame, and the product positioning member 231 limits the mobile phone middle frame through the plug interfaces, thereby limiting the mobile phone middle frame in the left and right and front and back directions, and improving the processing accuracy of the mobile phone middle frame. The flip mechanism 1 includes a flip table 13 and a plurality of locking components 12, and the supporting block 23 is arranged on the flip table 13, and the locking components are arranged on the flip table 13 and around the supporting block 23. In order to realize multi-angle compression, it is ensured that the cover plate 22 is pressed against the supporting block 23 under the cooperation of a plurality of locking components 12, and the compression effect of the cover plate 22 and the supporting block 23 can be effectively guaranteed.

[0064] Among them, a pressure limiting column 221 is inserted on the cover plate 22 and is positioned and matched with the supporting block 23. The pressure limiting column 221 is used to limit the shaking of the cover plate 22 and the supporting block 23 in the left and right and front and back directions, thereby improving the accuracy of the processing of the mobile phone middle frame and preventing the cover plate 22 from unilaterally tilting due to the multiple side push drive members 121 pushing the lock tongue 122 asynchronously, thereby affecting the limit of the cover plate 22 and the supporting block 23 in the up and down directions.

[0065] In the embodiment of the utility model, the supporting block 23 and the opposite side of the cover plate 22 are provided with grid grooves, which are in the form of horizontal and vertical cross grids. The setting of the grid grooves can effectively increase the friction between the cover plate 22, the supporting block 23 and the mobile phone middle frame, and can avoid the mobile phone middle frame from shifting during the processing, so that the processing accuracy of the mobile phone middle frame is higher. The top surface of the support block 3 is provided with vacuum adsorption holes, through which the mobile phone middle frame can be firmly fixed on the fitting surface of the support block 3, forming a Z-direction tensioning effect. This structural setting can effectively prevent the product thickness from being deformed or causing stress marks when it is processed to about 0.4mm.

[0066] like Figure 3 and Figure 4 As shown, in the embodiment of the utility model, the locking assembly 12 includes a side push driving member 121 and a locking tongue 122 arranged on the side push driving member 121, a bevel is arranged below the end of the locking tongue 122, and a bevel is arranged on the edge of the cover plate 22, and the bevel is slidably matched with the bevel, and the locking tongue 122 and the cover plate 22 are structurally matched, which can improve the locking effect of the locking tongue 122, so that the locking tongue 122 can efficiently press the cover plate 22 on the supporting block 23, realize the processing and locking of the mobile phone middle frame, and avoid the locking assembly 12 from occupying a large space. And the locking tongue 122 is miniaturized to avoid the locking tongue 122 from being too large and interfering with the moving mechanism 4. The CNC processing equipment includes a CNC start key connected to the locking assembly 12 for driving the locking assembly 12 to lock or unlock, and the locking tongue 122 is driven to extend through the CNC start key to press the cover plate 22 and the supporting block 23, so as to realize convenient control of the locking assembly 12. At the same time, the CNC start button is also connected to the motor inside the four-axis, and the motor drives the flip table 13 to flip. After the operator completes clamping the mobile phone middle frame through the cover plate 22, pressing the CNC start button can drive the flip table 13 to flip, so as to switch the TP surface and BP surface of the mobile phone middle frame and perform double-sided processing on the mobile phone middle frame.

[0067] When the mobile phone middle frame is processed on both sides, the product positioning member 231 of the mobile phone middle frame corresponding to the supporting block 23 is first installed to achieve the limitation of the mobile phone middle frame in the left and right and front and back directions, and then the cover plate 22 is pressed on the top of the mobile phone middle frame to achieve the limitation of the mobile phone middle frame in the up and down directions, and the pressure limiting column 221 is inserted into the pressure limiting hole opened on the supporting block 23 to achieve the limitation of the cover plate 22 in the left and right and front and back directions. Then, the side push driving member 121 drives the lock tongue 122 to extend close to the cover plate 22, and presses the cover plate 22 on the supporting block 23, at which time the cover plate 22 and the supporting block 23 are in a locked state. After the TP surface and BP surface of the mobile phone middle frame are processed, the side push driving member 121 drives the lock tongue 122 to retract away from the cover plate 22, at which time the cover plate 22 and the supporting block 23 are in an unlocked state. The cover plate 22 can be removed manually, and the processed mobile phone middle frame can be taken out, at which time the TP surface and BP surface of the mobile phone middle frame are processed.

[0068] In an embodiment of the utility model, a CNC processing device is provided, comprising the double-sided processing device as described above.
