[0018] A processing method for a mobile phone middle frame processing equipment includes the following steps:

[0019] S1. At the loading station, sleeved a number of middle frames on a number of inner support columns at the material fixing station of the loading part one by one, then embed the loading part into the loading seat, start the pusher to drive the loading seat to move forward linearly for feeding, and the picking claw on the turntable picks up the middle frame on the loading part for rotary transfer;

[0020] S2. The turntable rotates a certain angle, and the picking claw places the middle frame to the incoming material inspection station to check the integrity and defects of the middle frame. Qualified products are passed, and the middle frame is picked up by the picking claw again for rotation and transfer;

[0021] S3. The turntable rotates in a certain direction, and the picking claw places the middle frame on the cutting station. The optical fiber sensor senses that the middle frame is placed in the cavity and fixed. The control jack drives the lifting plate to rise, so that the pre-elevator block and the lower cutter extend correspondingly, and the waste part is supported by the pre-elevator block, and the connecting section of the waste is placed between a pair of positioning pins to form a flat fixation, and the lower cutter is pressed against the bottom surface of the waste cutting position; at the same time, the lower presser drives the lower pressing frame to descend, and the pre-pressing block presses the waste part to form a longitudinal fixation, and the upper cutter is pressed against the top surface of the waste cutting position. The upper cutter and the lower cutter cut together to cut the waste; the middle frame is sucked up by the picking claw again and rotated and transferred;

[0022] S4: The turntable rotates at an angle, and the pick-up claw places the middle frame on the first bending station. Several inner support blocks and positioning blocks are engaged with the internal structure of the middle frame to form a flat fixation for the middle frame. The presser is started to lower the press plate to the appropriate position, so that the bottom surface of the press head is pressed against the top surface of the middle frame, thus achieving longitudinal fixation of the middle frame.

[0023] Start the rotator to swing the shaft in a directional manner, and the bending shaft rotates synchronously through the belt drive, further driving the eccentric bending rod to swing a certain arc around the center of the bending shaft. At the same time, the pushing rod on the bending block fits the bottom surface of the hook component. Driven by the swing, the pushing rod pushes the hook component to bend along the arc trajectory into the groove of the middle frame; the middle frame is again picked up by the picking claw for rotation and transfer;

[0024] S5: The turntable rotates in a certain direction, and the material picking claw places the middle frame on the second bending station. Several inner support blocks and positioning blocks are engaged with the internal structure of the middle frame to form a flat fixation for the middle frame. The pressing device is started to lower the pressing plate to the appropriate position, so that the bottom surface of the pressing head is pressed against the top surface of the middle frame, thus achieving longitudinal fixation of the middle frame.

[0025] Start the rotator to swing the shaft in a directional manner, and the bending shaft rotates synchronously through the belt drive, further driving the eccentric bending rod to swing a certain arc around the center of the bending shaft. At the same time, the pressure wheel on the bending block fits the bottom surface of the hook component. Driven by the swing, the pressure wheel pushes the hook component to bend along the arc trajectory into the groove of the middle frame through the wheel surface; the middle frame is picked up by the picking claw again for rotation and transfer;

[0026] S6: The turntable rotates in a certain direction, and the pick-up claw places the middle frame on the height mesh inspection station. The height detection head detects the flatness of the top surface of the middle frame. The middle frame is picked up by the pick-up claw again and rotated and transferred.

[0027] S7. The turntable rotates directionally by an angle, and the picking claw places the middle frame at the yaw angle workstation. The yaw angle of the middle frame is detected by the yaw angle detection head; the middle frame is sucked again by the picking claw for rotary transfer.

[0028] S8. The turntable rotates directionally by an angle, and the picking claw places the middle frame on the blanking table at the blanking workstation. The transverse conveyor belt drives the material moving claw to move above the blanking table, the lifter lowers the material moving claw, and the rotator rotates the material moving claw to adjust the adaptation angle. The material moving claw sucks the middle frame on the blanking cavity, and the transverse conveyor belt drives the material moving claw to return.

[0029] If the picked middle frame is a defective product, it is moved above the baffle hopper and the material moving claw releases the middle frame. The defective middle frame is conveyed to the defective receiving box through the lower transmission platform.

[0030] If the picked middle frame is a qualified product, it is moved above the upper transmission platform and the material moving claw releases the middle frame. The qualified middle frame is conveyed to the qualified product receiving box through the upper transmission platform.

Specific embodiments

[0045] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0046] Embodiment 1

[0047] Such as Figure 1As shown in the figure, the processing equipment for the middle frame of this mobile phone includes a turntable 1. A number of material taking claws 101 are arranged in a circumferential annular array on the turntable 1. A feeding station 2, a feeding detection station 3, a cutting station 4, a first bending station 5, a second bending station 6, a height mesh cloth detection station 7, a yaw station 8 and a discharging station 9 are sequentially arranged on the outer periphery of the turntable 1.

[0048] As Figure 2 shown, the feeding station 2 includes at least one feeding table 201. A feeding seat 202 is slidably arranged on the feeding table 201. The feeding seat 202 is driven and connected by a pusher 204. A loading member 207 is embedded in the feeding seat 202. A number of material positioning stations are arranged in an array on the loading member 207, and a material positioning assembly is arranged in the material positioning stations. A number of sliders are fixedly arranged on the feeding table 201. Guide rails are fixedly arranged on the bottom surface of the feeding seat 202. The guide rails are correspondingly clamped into the sliders to form a sliding connection. The number of sliders is divided into two columns. Two guide rails are correspondingly fixedly arranged on the bottom surface of the feeding seat 202, and the two guide rails are correspondingly embedded into the two columns of sliders.

[0049] The pusher 204 is a pen-shaped air cylinder. A hinge seat 203 is fixedly arranged on the feeding table 201. The end of the pen-shaped air cylinder is hinged to the hinge seat 203 to form a rotational connection. A connection hook 206 is fixedly arranged on the side wall of the feeding seat 202. The telescopic end of the pen-shaped air cylinder is lapped on the connection hook 206 through a clamping shaft 205.

[0050] Start the pen-shaped air cylinder to drive the feeding seat 202 to slide linearly back and forth, so as to realize the successive feeding action. The tail end of the pen-shaped air cylinder has a swing margin. The telescopic end of the pen-shaped air cylinder can not only realize the push-pull transmission by lapping, but also realize the micro adjustment. When installing the pen-shaped air cylinder, if there is a deviation in the installation position, the installation efficiency can still be improved through the swing margin to ensure the accuracy of feeding.

[0051] A long strip card slot is recessed on the top surface of the feeding seat 202. The loading member 207 is a long strip body. The long strip body is clamped into the long strip card slot to form a disassembly and assembly connection. A number of material positioning stations are arranged along the length direction of the long strip body. The material positioning assembly includes a number of inner support columns 208 protruding from the top surface of the long strip body. First, manually sleeved a number of middle frames on the a number of inner support columns 208 of the material positioning stations, and then clamp the long strip body into the long strip card slot to complete the feeding.

[0052] The feeding detection station 3 includes a first detection table. A first sensor is arranged below the first detection table, and a detector one is driven to translate above the first detection table. The first sensor senses that a middle frame is placed on the first detection table, and the detector one checks the surface of the middle frame for defects.

[0053] As Figures 3 to 5As shown, the cutting station 4 includes an upper die cutting assembly and a bottom die cutting assembly that cooperate up and down. The bottom die cutting assembly includes a base 401, on which a material loading plate 402 is arranged. At least one cavity is formed on the material loading plate 402. A lower cutting module is driven by a lifter 403 inside the base 401; the upper die cutting assembly includes a bracket, and an upper cutting module is driven by a lower pressure device 407 on the bracket.

[0054] The cavity includes a groove, and the bottom wall of the groove has a profiling support table and a hollow window. The bottom surface of the middle frame is fitted and supported by the profiling support table to maintain the stability of the placement of the middle frame. Two hollow windows are arranged on the left and right in each cavity. The two hollow windows are set according to the cutting position, and a cutting space for up and down cutting is provided through the hollow windows. The middle frame is placed in the cavity for fixation. The lower pressure device 407 drives the upper cutting module to descend, and at the same time, the lifter 403 drives the lower cutting module to ascend. Through the alignment and fitting of the upper and lower cutting modules, the waste on the middle frame is cut off.

[0055] The lower cutting module includes a lifting plate. The lifting rod of the lifter 403 is fixedly connected to the bottom surface of the lifting plate. A plurality of lower cutting knives 406 protrude from the top surface of the lifting plate. A pre-lifting block 404 is sleeved on the lower cutting knife 406, and a pair of positioning pins 405 protrude from the top surface of the pre-lifting block 404. Each cavity corresponds to two groups of pre-lifting blocks 404, positioning pins 405 and lower cutting knives 406. The lifter 403 drives the lifting plate to ascend, so that the two groups of pre-lifting blocks 404 and lower cutting knives 406 correspondingly extend out from the hollow window. First, the waste part is supported by the pre-lifting block 404, then the connecting section of the waste is placed between a pair of positioning pins 405 to form a fixation, and finally the lower cutting knife 406 is abutted against the bottom surface of the waste cutting position.

[0056] An optical fiber sensor is arranged inside the base 401, and the sensing probe of the optical fiber sensor extends to the side of the cavity. By sensing the placement of the middle frame in the cavity with the optical fiber sensor, and then controlling the upper die cutting assembly and the bottom die cutting assembly to move synchronously for cutting operation.

[0057] The upper cutting module includes a downward pressing frame 408. The downward pressing rod of the lower press 407 is fixedly connected to the top surface of the downward pressing frame 408. A pre-pressing block 409 protrudes upward from the bottom surface of the downward pressing frame 408. The downward pressing frame 408 protrudes upward with upper cutting knives 410 on both sides of the pre-pressing block 409. The bottom end of the upper cutting knife 410 protrudes from the bottom surface of the pre-pressing block 409. A housing 411 is sleeved on the outer periphery of the upper cutting knife 410. The bottom end of the upper cutting knife 410 protrudes from the bottom opening of the housing 411. A limiting post 412 protrudes upward from the bottom surface of the downward pressing frame 408. The length of the limiting post 412 is less than the length of the upper cutting knife 410. Each cavity corresponds to two groups of pre-pressing blocks 409 and upper cutting knives 410. The limiting posts 412 protrude symmetrically on the opposite sides of the bottom surface of the downward pressing frame 408. The lower press 407 drives the downward pressing frame 408 to descend. First, the waste part is pressed by the pre-pressing block 409 to form longitudinal fixation. Then, the upper cutting knife 410 abuts against the top surface of the waste cutting position. At the same time, the bottom edge of the housing 411 presses the peripheral waste part of the cutting, improving the stability of the cutting.

[0058] A number of guiding columns are arranged on the bracket, and a number of guiding sleeves are correspondingly arranged on the downward pressing frame 408. The number of guiding sleeves are sleeved on the corresponding guiding columns one by one to form a sliding connection. Through the sliding connection of the guiding columns and the guiding sleeves, guiding and stability are provided during the lifting and lowering process of the upper cutting module, thereby ensuring the precise cooperation between the upper cutting knife 410 and the lower cutting knife 406, effectively completing the cutting process, and ensuring the smoothness of the cutting edge.

[0059] As Figure 6 and Figure 7 As shown in

[0060] The first bending station 5 / second bending station 6 includes a material loading seat. At least one material fixing table 601 is arranged on the material loading seat. An inner support component is arranged on the material fixing table 601. A folding material notch is arranged on one side of the material fixing table 601. A pressing mechanism is erected above the material loading seat. A positioning sliding table is arranged beside the material loading seat. A rotation mechanism is driven to translate on the positioning sliding table. The rotation mechanism has an eccentric bending rod 610. The eccentric bending rod 610 extends into the folding material notch and forms an arc trajectory driven by the rotation mechanism.

[0061] The pressing mechanism includes a stand, mounted with a press 602. The downward-facing pressing rod of the press 602 is fixed to a pressing plate 603. A pressing block 604 is fixed to the pressing plate 603, corresponding to the material placement platform 601. The bottom surface of the pressing block 604 is secured with at least two pressing heads. These pressing heads are made of rubber blocks, and their flexibility cushions and holds the product, preventing surface damage. Activating the press 602 lowers the pressing plate 603 to the desired position, allowing the bottom surfaces of the pressing heads to press against the top surface of the middle frame, securing the middle frame longitudinally and improving the accuracy of the bending and fitting process.

[0062] The positioning slide comprises a base plate 605, mounted with parallel expansion joints 606 and cross rails. The expansion joint 606's telescopic axis is fixedly connected to a slide plate, and a cross block is fixed to the bottom of the slide plate, which snaps onto the cross rails to form a sliding guide. The expansion joint 606 drives the slide plate to move back and forth, synchronously driving the rotation mechanism to translate and adjust, thereby accurately positioning the eccentric bending rod 610 relative to the folding notch, facilitating subsequent precise folding.

[0063] The rotating mechanism includes a base 607, on which a rotator is mounted. The rotating shaft of the rotator is connected to a bending swing shaft 609 via a belt 608. Both ends of the bending swing shaft 609 are hinged to the base 607. The ends of the bending swing shaft 609 are fixedly connected to an eccentric bending rod 610. Figure 8 As shown, a bending block 611 is fixed vertically on the eccentric bending rod 610 of the first bending station 5, and the end of the bending block 611 is an integral protruding push rod 501. When the hook component is a straight thin hook structure, there is no need to use the pressure wheel 612 to perform large-area rolling and bending. It is only necessary to use the push rod 501 of the corresponding width to directly press and bend it. Figure 9 As shown, a bending block 611 is vertically fixed to the eccentric bending rod 610 of the second bending station 6, and a pressure roller 612 is hinged at the end of the bending block 611. The rotator is activated to directional swing the shaft, and the bending swing shaft 609 is synchronously rotated via the belt 608, further driving the eccentric bending rod 610 to swing a certain arc around the center of the bending swing shaft 609. At the same time, the pressure roller 612 on the bending block 611 is in contact with the bottom surface of the hook component. Driven by the swinging, the pressure roller 612 pushes the hook component along an arc trajectory through the wheel surface to bend into the groove of the middle frame. The pressure roller 612 can also rotate during the pushing process, so that the hook component can roll and rub at different bending angles. This can not only improve the pushing fit, but also avoid indentations or creases on the surface of the hook component.

[0064] like Figure 8As shown in the figure, two limiting rods 502 are fixedly arranged on the base 607, and a blocking block is convexly provided on the outer side of the eccentric bending rod 610. The blocking block is located between the two limiting rods 502. The blocking block rotates with the eccentric bending rod 610. When the blocking block abuts against any one of the limiting rods 502, the eccentric bending rod 610 stops rotating further, realizing the limitation of the rotation angle of the eccentric bending rod 610 and avoiding incomplete or excessive bending.

[0065] The height mesh cloth inspection station 7 includes a second inspection table. A detector two is driven by X-direction translation and Y-direction translation beside the second inspection table, and the surface of the middle frame is inspected for height through the detector two.

[0066] The yaw degree station 8 includes a third inspection table. A sensor two is arranged below the third inspection table, and a detector three is driven to lift above the third inspection table. When the sensor two senses that a middle frame is placed on the third inspection table, the surface of the middle frame is inspected for yaw degree through the detector three.

[0067] As Figure 10 shown, the blanking station 9 includes a blanking table 901, a transfer mechanism and a blanking conveying mechanism. There is at least one material placing cavity on the blanking table 901; the transfer mechanism includes a transverse moving plate driven by a transverse moving conveyor belt 902. A lifter 903 is installed on the transverse moving plate. The lifting end of the lifter 903 is fixedly connected to a rotator 904, and the rotating end of the rotator 904 is fixedly connected to a material moving claw 905; the blanking conveying mechanism includes an upper conveying platform 906 and a lower conveying platform. A material blocking hopper 907 is arranged at the head end of the lower conveying platform, and a defective product receiving box is connected to the tail end of the lower conveying platform.
