Description

Technical Field

[0001] This invention relates to the field of CNC machining technology for mobile phone frames, and particularly to an automatic feeding and storage system for a machining center for mobile phone frames. Background Technology

[0002] The mobile phone frame refers to the middle frame of a mobile phone, which consists of the outer frame, the middle connecting frame, and the inner frame. It is mostly made of aluminum alloy, titanium alloy, etc. The processing of the mobile phone frame requires the use of CNC machining. CNC machining refers to the numerical control machining center inputting information into the numerical control device through the information carrier, which then processes the information and sends out various control signals to control the machine tool's movements. According to the shape and size required by the drawings, it automatically performs turning, drilling, and other processing on the mobile phone frame.

[0003] While existing CNC machining achieves full automation during the process, it can only process one set of mobile phone frames at a time. After processing one set of mobile phone frames, workers need to remove the processed mobile phone frames, place the blanks to be processed, and proceed with the next processing. The entire process is time-consuming and labor-intensive, and it greatly limits the number of operators who can manage the machining center.

[0004] Therefore, there is an urgent need for a system that can store and automatically load blanks inside a CNC machining center to replace manual loading. Summary of the Invention

[0005] To address the above problems, this invention provides an automatic feeding and storage system for mobile phone frame machining centers. By setting up a storage system inside the machining center, the system enables the storage and fully automatic feeding of blanks. This allows the blanks stored inside the machining center to be loaded onto the clamping fixtures one by one in an orderly manner. Simultaneously, the finished mobile phone frames can be automatically unloaded, thereby reducing manual intervention, shortening the operation time of each machining center, and significantly increasing the number of machining centers that an operator can manage per unit time, further enhancing the level of automation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automated feeding and storage system for a mobile phone frame machining center includes:

[0008] Machining center and storage system;

[0009] The machining center includes a machining center spindle and a clamping fixture. The material storage system includes a material storage component and a material gripping component. The machining center spindle is located above the clamping fixture. The material storage component is arranged parallel to the clamping fixture. The material gripping component is integrally connected to the machining center spindle. The machining center spindle drives the material gripping component to move. The material gripping component grabs the blank stored in the material storage component and transfers it to the clamping fixture, where it is machined by a cutting tool on the machining center spindle.

[0010] As an improvement, the clamping fixture includes a clamping platform, a clamping cylinder, and a clamping block;

[0011] The clamping platform is horizontally arranged, and several sets of clamping cylinders and clamping blocks are arranged in a one-to-one correspondence, with the clamping cylinders and clamping blocks distributed around the four sides of the clamping platform.

[0012] The clamping cylinder is vertically arranged, and the clamping block is installed on the movable end of the clamping cylinder. The clamping block is driven by the clamping cylinder to rotate and press down.

[0013] As an improvement, side positioning components are respectively provided on any two adjacent sides of the clamping platform. The side positioning components include positioning cylinders and positioning rods. The positioning cylinders are installed horizontally, and the positioning rods are installed at the movable end of the positioning cylinders. The positioning rods are driven by the positioning cylinders and press against the side wall of the blank.

[0014] As an improvement, the storage assembly includes a storage platform, a support column, and a positioning pin;

[0015] The storage platform is horizontally set and divided into several storage areas. The support columns are grouped in groups of four, and the groups of support columns correspond one-to-one with the storage areas. The support columns are distributed on the storage platform, and the support columns in each group are arranged in a square. The support columns support the billet.

[0016] The positioning pins are distributed within the square formed by the support columns in each group. There are two groups of positioning pins within the square, and the positioning pins are interlocked with the positioning holes on the blank.

[0017] As an improvement, the positioning pin is installed within the square formed by the support column via an installation strip, and the installation strip is movable and adjustable within the square.

[0018] As an improvement, the material gripping assembly includes a lifting cylinder, a mounting connecting plate, and a pneumatic suction nozzle;

[0019] The lifting cylinder is installed on the side wall of the machining center spindle, and the lifting cylinder is extended and retracted downwards.

[0020] The mounting connecting plate is installed on the telescopic end of the lifting cylinder;

[0021] The pneumatic suction nozzle is mounted on the mounting connection plate, and there are several groups of the pneumatic suction nozzle.

[0022] As an improvement, an air nozzle is provided below the spindle of the machining center to blow away metal shavings on the clamping fixture.

[0023] The mounting plate is equipped with a main cleaning nozzle, which performs air jet cleaning on the upper surface of the blank stored on the material storage assembly.

[0024] An auxiliary cleaning nozzle is provided on one side of the storage platform. The auxiliary cleaning nozzle performs air cleaning on the lower surface of the billet picked up by the material gripping component.

[0025] As an improvement, a lifting system is provided below the storage platform. This lifting system tilts and lifts the billets temporarily stored on the storage platform, so that the temporarily stored billets are placed in an inclined state.

[0026] The lifting system includes a lifting component and a turntable component. The lifting component is set one-to-one with the storage area. The lifting component lifts the corresponding billet and tilts the billet.

[0027] The turntable assembly is located below the lifting assembly, and the turntable assembly drives the lifting assembly to lift and set.

[0028] As an improvement, the lifting assembly includes a mounting base, a lifting rod, a support plate, a spring, a guide sleeve, a guide ring, and a sensor;

[0029] The mounting base is installed below the storage platform, and a guide sleeve is provided on the mounting base;

[0030] The lifting rod passes through the guide sleeve and is eccentrically positioned relative to the storage area. A zigzag groove is provided on the side wall of the lifting rod.

[0031] The support plate is installed on the top of the lifting rod, and the support plate extends from the lifting rod across the center of the storage area to the other side of the storage area;

[0032] The spring is sleeved on the lifting rod, and the spring is compressed as the lifting rod is raised;

[0033] The guide ring is fixedly installed below the mounting base. The guide ring is sleeved on the outside of the lifting rod, and the inner sidewall of the guide ring has a pin protruding inward. When the lifting rod is raised, the pin and the groove are correspondingly inserted and engaged, so that the lifting rod can be rotated 90°.

[0034] The sensor is mounted on the mounting base and detects the blank in the corresponding storage area.

[0035] As an improvement, the turntable assembly includes a rotary disk and an electric spindle;

[0036] The rotating disk is rotatably mounted below the lifting assembly. The rotating disk has several protrusions that abut against the lower end of the corresponding lifting rod, causing the lifting rod to rise.

[0037] The electric spindle is located below the rotating disk, and the electric spindle drives the rotating disk to rotate.

[0038] The beneficial effects of this invention are as follows:

[0039] (1) This invention sets up a material storage system inside the processing center and uses the material storage components of the material storage system to store multiple blanks to be processed. At the same time, with the fully automatic feeding of the material gripping component, the blanks stored inside the processing center can be loaded onto the clamping fixture of the processing center one by one in an orderly manner. Meanwhile, the processed mobile phone frame can also be automatically unloaded, thereby reducing manual intervention, shortening the operation time of the operator on each processing center, and greatly increasing the number of processing centers that the operator can manage per unit time, further improving the degree of automation and enhancing the processing efficiency.

[0040] (2) The material storage component of the present invention, through the cooperation of the support column and the positioning pin, allows the billet to be temporarily stored in the storage area. The positioning hole on the billet can cooperate with the positioning pin to ensure the accurate positioning of the billet storage. At the same time, the support column can accurately support the four corners of the billet, maintain the stability of the billet when it is gripped by the material gripping component, and ensure the accuracy of the material gripping component in gripping the billet.

[0041] (3) Before gripping the blank, the gripping assembly of the present invention first cleans the upper surface of the blank through the main cleaning nozzle to remove the waste and cutting oil on the surface of the blank, and then grips the blank, ensuring the stability and accuracy of gripping. After the gripping assembly finishes gripping the blank, the lower surface of the blank is also cleaned through the auxiliary cleaning nozzle set below, ensuring the accuracy and flatness of the blank when it is loaded onto the clamping fixture.

[0042] (4) By setting up a lifting system, the present invention allows the billet to be in an inclined state when it is stored on the storage component, so that the waste chips and cutting oil generated during the machining in the machining center will not accumulate on the upper surface of the billet. Moreover, when the main cleaning nozzle cleans the billet, the inclined billet is more conducive to the flow of air on the upper surface of the billet for cleaning, and the cleaning effect is better.

[0043] (5) The lifting system provided in this invention first lifts the billet vertically when tilting it, and then tilts the billet, so that the billet always has a positioning hole that is interlocked with the positioning pin, thereby ensuring the accuracy of loading and positioning when the billet is tilted and then restored to horizontal, and improving the processing accuracy.

[0044] In summary, this invention has the advantages of high processing accuracy, good processing stability, and high processing efficiency, and is especially suitable for the field of automatic CNC machining technology for mobile phone frames. Attached Figure Description

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0062] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0063] Example 1:

[0064] like Figures 1-7 As shown, an automatic feeding and storage system for a mobile phone frame machining center includes:

[0065] Machining center 1 and storage system 2;

[0066] The machining center 1 includes a machining center spindle 11 and a clamping fixture 12. The material storage system 2 includes a material storage component 21 and a material gripping component 22. The machining center spindle 11 is located above the clamping fixture 12. The material storage component 21 and the clamping fixture 12 are arranged in parallel. The material gripping component 22 is integrally connected to the machining center spindle 11. The machining center spindle 11 drives the material gripping component 22 to move. The material gripping component 22 grips the blank 10 stored in the material storage component 21 and transfers it to the clamping fixture 12, where it is cut by the cutting tool on the machining center spindle 11.

[0067] It should be noted that the machining center in this invention differs from existing machining centers in that, through the material storage system 2, the machining center can store several sets of blanks 10 while simultaneously cutting one set of blanks. After one set of blanks 10 is processed, the material storage system 2 will replace it with another set of blanks 10. Specifically, in this invention, it is preferred that the number of blanks 10 stored in the machining center is 4 sets. However, the number of blanks 10 in this invention is not limited to 4 sets; it can be 5 sets, 6 sets, 7 sets, 8 sets, etc. Any number of blanks that meets the requirements of this invention is within the protection scope of this invention.

[0068] Furthermore, in this invention, the blank 10 is stored on the storage component 21, and the blank 10 on the storage component 21 is picked up and transferred to the clamping fixture 12 by the gripping component 22.

[0069] Among them, such as Figure 2 As shown, the specific structure of the clamping fixture 12 for fixing the blank 10 includes a clamping platform 121, a clamping cylinder 122, and a clamping block 123.

[0070] The clamping platform 121 is horizontally arranged, and several sets of clamping cylinders 122 and clamping blocks 123 are arranged in a one-to-one correspondence. The clamping cylinders 122 and clamping blocks 123 are distributed around the four sides of the clamping platform 121. Specifically, two sets of clamping cylinders 122 are arranged on one side of the clamping platform 121 corresponding to the length direction of the billet 10. The two sets of clamping cylinders 122 are symmetrically arranged along the center line of the length direction of the billet 10. On the clamping platform 121, one set of clamping cylinders 122 is arranged on the center line of the width direction of the billet 10. Each set of clamping cylinders 122 is vertically arranged. The clamping block 123 is equipped with the movable end of the clamping cylinder 122. The clamping block 123 is driven by the clamping cylinder 122 to rotate and press down.

[0071] Specifically, the clamping cylinder 122 is preferably an Airtac-QCK series clamping cylinder structure, which can drive the clamping block 123 to rotate 90° and then descend to press the edge of the blank 10. Conversely, when releasing, the clamping block 123 is first raised and then rotated 90°. The structure of the clamping cylinder 122 is the existing clamping cylinder structure, so it will not be described in detail.

[0072] Furthermore, a side positioning component 13 is provided on each of the two adjacent sides of the clamping platform 121. The side positioning component 13 includes a positioning cylinder 131 and a positioning rod 132. The positioning cylinder 131 is installed horizontally, and the positioning rod 132 is installed at the movable end of the positioning cylinder 131. The positioning rod 132 is driven by the positioning cylinder 131 and presses against the side wall of the blank 10.

[0073] Since the material gripping component 22 will have a certain error in the placement position each time it grips the blank 10 and puts it onto the clamping platform 121, and the most important thing to pay attention to in the processing of mobile phone frame is the impact of the error on dimensional accuracy, in order to ensure the clamping accuracy of the clamping fixture 12 on the blank 10, the side positioning component 13 is set to position the blank 10 gripped and placed by the material gripping component 22 at the center position of the clamping platform 121 each time. Specifically, the side positioning component 13 pushes the blank 10 laterally in the width direction and the length direction respectively, thereby realizing the centering of the blank 10.

[0074] In addition, such as Figures 6-7 As shown, the storage assembly 21 for storing the blank 10 specifically includes a storage platform 211, a support column 212, and a positioning pin 213;

[0075] The storage platform 211 is horizontally arranged and divided into several storage areas 210. Each storage area 210 stores a set of blanks 10. Each blank 10 is supported by four support columns 212 arranged at the four corners. Each storage area 210 is provided with a set of support columns 212 arranged at the four corners. The support columns 212 are installed on the storage platform 211.

[0076] The positioning pins 213 are distributed within the square formed by the support columns 212 in each group. There are two groups of positioning pins 213 within the square. The positioning pins 213 are interlocked with the positioning holes 100 on the blank 10 to achieve the purpose of positioning the blank 10.

[0077] Furthermore, the positioning pin 213 is installed within the square formed by the support column 212 via the mounting strip 214, and the mounting strip 214 is movable and adjustable within the square. This means that the position of the positioning pin 213 can be adjusted according to the position of the positioning hole 100 on the blank 10, thus making it suitable for positioning blanks of different specifications and models.

[0078] Furthermore, on a set of adjacent sides of each storage area 210, there are transverse and longitudinal limiting strips 2100 respectively. The function of the limiting strips 2100 is to ensure that when the billet 10 is lifted into an inclined state, the billet 10 is blocked and limited, and will not move out of the storage area 210. At the same time, it also ensures that when the lifting rod 312 rotates, it can prevent the billet 10 from rotating with the lifting rod 312.

[0079] In addition, such as Figure 3 As shown, the specific structure of the material gripping assembly 22 used for loading and unloading the blank 10 includes a lifting cylinder 221, a mounting connecting plate 222, and a pneumatic suction nozzle 223;

[0080] The lifting cylinder 221 is installed on the side wall of the machining center spindle 11, and the lifting cylinder 221 is arranged to extend and retract downwards;

[0081] The mounting connecting plate 222 is installed on the telescopic end of the lifting cylinder 221;

[0082] The pneumatic suction nozzle 223 is mounted on the mounting connection plate 222, and there are several groups of the pneumatic suction nozzle 223.

[0083] Specifically, the lifting cylinder 221 moves and adjusts along the X, Y, and Z axes with the machining center spindle 11, while the lifting cylinder 221 drives the mounting connecting plate 222 to move up and down in the Z axis direction. The pneumatic suction nozzle 223 adsorbs the blank 10 through vacuum adsorption, thus completing the loading and unloading of the blank 10.

[0084] Example 2:

[0085] like Figure 3 As shown, an automatic feeding and storage system for a mobile phone frame machining center is provided. An air nozzle 14 is provided below the main spindle 11 of the machining center. The air nozzle 14 blows air to clean the metal scraps on the clamping fixture 12.

[0086] The mounting connection plate 222 is equipped with a main cleaning nozzle 23, which performs jet cleaning on the upper surface of the blank 10 stored on the material storage assembly 21.

[0087] An auxiliary cleaning nozzle 24 is provided on one side of the storage platform 211. The auxiliary cleaning nozzle 24 performs air cleaning on the lower surface of the blank 10 picked up by the material gripping component 22.

[0088] Furthermore, the jet nozzle 14, the main cleaning nozzle 23, and the auxiliary cleaning nozzle 24 are all connected to an external air supply device via air pipes.

[0089] It should be noted that before the blank 10 is cut by the machining center, the upper and lower surfaces of the blank 10 need to be air-cleaned to ensure that the upper and lower surfaces of the blank 10 are in a clean state. When the blank 10 is mounted on the clamping fixture 12, the lower surface will not lose clamping accuracy due to cleanliness issues, and the upper surface will not lose machining accuracy due to cleanliness issues.

[0090] Specifically, before the gripping assembly 22 grips the billet 10, the air nozzle 14 located below the machining center spindle 11 first performs air blowing cleaning on the clamping fixture 12 to ensure that the metal scraps on the clamping fixture 12 are cleaned. Then, the machining center spindle 11 moves to move the gripping assembly 22 above the storage assembly 21, and the main cleaning nozzle 23 performs air blowing cleaning on the upper surface of the billet 10. After cleaning, the gripping assembly 22 performs vacuum adsorption gripping on the billet 10, and the gripped billet 10 is transferred. Before transferring the billet 10 to the clamping fixture 12, the lower surface of the billet 10 needs to be air blown cleaned by the auxiliary cleaning nozzle 24.

[0091] Example 3:

[0092] like Figures 8-14As shown, a lifting system 3 is provided below the storage platform 211. The lifting system 3 tilts and lifts the temporarily stored blank 10 on the storage platform 211, so that the temporarily stored blank 10 is placed in an inclined state. When the blank 10 is processed in the machining center, the splashed metal scrap and cutting oil are difficult to adhere to the surface of the blank 10. Instead, they fall off the inclined surface of the blank 10, which largely avoids the accumulation of metal scrap and cutting oil on the surface of the blank 10. At the same time, when the main cleaning nozzle 23 cleans the metal scrap and cutting oil on the upper surface of the blank 10, the airflow can more smoothly remove the metal scrap and cutting oil from the upper surface of the blank 10.

[0093] The lifting system 3 specifically includes a lifting component 31 and a turntable component 32. The lifting component 31 is arranged in a one-to-one correspondence with the storage area 210. The lifting component 31 lifts the corresponding billet 10 and tilts the billet 10.

[0094] The turntable assembly 32 is located below the lifting assembly 31, and the turntable assembly 32 drives the lifting assembly 31 to be lifted and set.

[0095] Specifically, such as Figures 10-13 As shown, the lifting assembly 31 for lifting the billet 10 specifically includes a mounting base 311, a lifting rod 312, a support plate 313, a spring 314, a guide sleeve 315, a guide ring 316, and a sensor 318.

[0096] The mounting base 311 is installed below the storage platform 211, and a guide sleeve 315 is provided on the mounting base 311;

[0097] The lifting rod 312 passes through the guide sleeve 315. The lifting rod 312 is eccentrically arranged relative to the storage area 210, and a zigzag groove 310 is opened on the side wall of the lifting rod 312. A roller or ball is provided at the bottom of the lifting rod 312.

[0098] The support plate 313 is installed on the top of the lifting rod 312, and the support plate 313 extends from the lifting rod 312 across the center of the storage area 210 to the other side of the storage area 210.

[0099] The spring 314 is sleeved on the lifting rod 312, and the spring 314 is compressed as the lifting rod 312 is lifted.

[0100] The guide ring 316 is fixedly installed below the mounting base 311. The guide ring 316 is sleeved on the outside of the lifting rod 312, and the inner sidewall of the guide ring 316 has a pin 317 protruding inward. When the lifting rod 312 is raised, the pin 317 and the groove 310 are correspondingly inserted and engaged, so that the lifting rod 312 can be rotated 90°. The groove 310 is composed of a vertical section and an inclined section. The vertical section allows the lifting rod 312 to be raised vertically, and the inclined section allows the lifting rod 312 to be raised and rotated at the same time.

[0101] The sensor 318 is mounted on the mounting base 311. The sensor 318 senses and detects the blank 10 in the corresponding storage area 210. When the sensor 318 does not sense the blank 10 in the corresponding storage area 210, the sensor 318 will send a signal to the electric spindle 322. After receiving the command, the electric spindle 322 drives the rotating disk 321 to rotate. Through the cooperation of the protrusion 323 and the lifting rod 312, the remaining blanks 10 are lifted. Through the repeated sensing of the sensor 318, control signals are repeatedly sent to the electric spindle 322, thereby controlling the rotation switching of the rotating disk 321.

[0102] It should be noted that when the lifting rod 312 is lifted upward, the lifting rod 312 and the support plate 313 work together to lift the billet 10 upward. At this time, the support plate 313 is set parallel to the length direction of the billet 10. After being lifted a certain distance, since the positioning pin 213 is set in a conical shape, the positioning hole 100 on the billet 10 and the tip of the positioning pin 213 will make the billet 10 tilt back and forth.

[0103] To further explain, after the lifting rod 312 is raised to a certain distance, the lifting rod 312 will rotate around its own axis. The rotation of the lifting rod 312 will cause the support plate 313 to swing to be parallel to the width direction of the billet 10. At this time, due to the center of gravity of the billet 10, the billet 10 will swing at the lifting rod 312, causing the billet 10 to tilt.

[0104] Furthermore, it should be emphasized that when the lifting rod 312 is raised, the zigzag groove 310 on the lifting rod 312 will cooperate with the pin 317, so that when the pin 317 and the inclined section of the groove 310 are engaged, the lifting rod 312 can rotate and swing, and the rotation and swing angle of the lifting rod 312 is 90°.

[0105] It should also be noted that the four sets of billets 10 stored in the storage area 210 are all inclined toward the clamping fixture 12 on the side closer to the clamping fixture 12, while the billets 10 on the side farther away from the clamping fixture 12 are inclined toward the other side.

[0106] Furthermore, such as Figure 9As shown, the turntable assembly 32 used to drive the lifting assembly 31 to operate specifically includes a rotary disk 321 and an electric spindle 322;

[0107] The rotating disk 321 is rotatably mounted below the lifting assembly 31. The rotating disk 321 has a plurality of protrusions 323, which abut against the lower end of the corresponding lifting rod 312, thereby raising the lifting rod 312.

[0108] The electric spindle 322 is located below the rotating disk 321, and the electric spindle 322 drives the rotating disk 321 to rotate.

[0109] It should be noted that the rotating disk 321 is driven to rotate by the electric spindle 322. The protrusion 323 provided on the rotating disk 321 abuts against the lower end of the lifting rod 312, thereby causing the lifting rod 312 to rise.

[0110] Furthermore, in this invention, it is preferred to store four sets of blanks 10, while the rotating disk 321 is provided with only three sets of protrusions 323 and a blank area 324. The blank area 324 cooperates with the lifting rod 312 in the storage area 210 where there are no blanks 10. Specifically, four blanks 10 are stored, and four sets of lifting rods 312 are provided accordingly, while there are three sets of protrusions 323 on the rotating disk 321. When storing blanks 10, the protrusions 323 on the rotating disk 321 do not cooperate with the lifting rods 312. However, when one set of blanks 10 is removed for processing, the rotating disk 321 rotates, causing the three sets of protrusions 323 to come into contact with the lifting rods 312 below the still-stored blanks 10, thus eliminating the need for further processing. The lifting rod 312 in the storage area 210 without blank 10 in zone 324 is raised, thereby tilting the stored blank 10. When the removed blank 10 is processed and stored back in the corresponding storage area 210, the rotary disk 321 will rotate again, so that the empty position on the rotary disk 321 is engaged with the lifting rod 312 below the next set of blank 10 to be processed, so that the blank 10 to be processed will not be raised or tilted. The completion of processing will also raise and tilt the blank 10 in the storage area 210, so that metal chips and cutting fluid will not accumulate on the finished blank 10. This cycle continues until all blanks 10 are processed.

[0111] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
