Description

Technical Field

[0001] The invention relates to the technical field of mobile phone outer frame assembly and molding, in particular to a mobile phone metal outer frame rapid molding processing equipment. Background Art

[0002] As an important component of a mobile phone, the metal frame of a mobile phone is usually made of aluminum alloy, stainless steel and other materials and is carved through precise CNC processing technology. It not only has smooth lines and outstanding texture, but also has both strength and toughness. It can provide reliable protection for the precision components inside the mobile phone and resist damage caused by daily bumps and falls.

[0003] As the instruction manual Fig.15 As shown, the figure shows a metal outer frame of a mobile phone in the prior art, which is mainly composed of a large U-shaped frame 01, a small U-shaped frame 02 and a middle plate 04. The inner edges of the large U-shaped frame 01 and the small U-shaped frame 02 are provided with a card slot 03 for the middle plate 04 to match and mount. During assembly, the large U-shaped frame 01 and the small U-shaped frame 02 are mounted on the middle plate 04, and the buckle 012 is matched and buckled into the card slot 021. The large U-shaped frame 01 and the small U-shaped frame 02 are assembled to form a side frame of the mobile phone, and the side frame of the mobile phone and the middle plate 04 form the whole middle frame of the mobile phone.

[0004] Among them, the difference between the large U-shaped frame 01 and the small U-shaped frame 02 is that the side of the large U-shaped frame 01 is much longer than the side of the small U-shaped frame 02. Since the long side 011 of the large U-shaped frame 01 is longer, its bending rigidity is lower than that of the side of the small U-shaped frame 02 under structural characteristics. Therefore, the long side 011 is prone to deformation during the grooving and hole opening processing and clamping and transfer process, and is affected by the deformation caused by the outside world and the error caused by the processing, so that the two long sides 011 of the large U-shaped frame 01 are not perpendicular enough to their short sides, and there is a situation of tilting inward or outward. During the subsequent assembly, the buckle 012 and the slot 021 have a large misalignment, which makes it impossible for the buckle 012 to be accurately inserted into the slot 021, and there is a situation of assembly failure.

[0005] Therefore, in the assembly and molding process of the traditional mobile phone middle frame, it is necessary to pre-detect the long side 011 of the large U-shaped frame 01. Only when the angles between the two long sides 011 and the short sides on the large U-shaped frame 01 meet the assembly requirements, can the large U-shaped frame 01 and the small U-shaped frame 02 be smoothly assembled. If the detection does not meet the requirements, the bend of the long side 011 needs to be straightened, and the large U-shaped frame 01 needs to be frequently transferred. The detection and straightening process undoubtedly increases the process flow before the assembly of the mobile phone middle frame, which is time-consuming and labor-intensive, and greatly reduces the assembly and molding efficiency. Summary of the invention

[0006] The purpose of the present invention is to provide a mobile phone metal frame rapid prototyping processing equipment to solve the technical problems raised in the above background technology.

[0009] Among them, when the inner clamp plate slides up to the extreme position, a positioning guide groove is formed between the inner side of the outer clamp plate and the bottom end surface of the inner clamp plate on the same side, which is used to guide the buckle to align with the slot, and the guiding bevel A in the straightening part is used to guide and straighten the long side edge inclined outward, and the guiding bevel B in the straightening part is used to guide and straighten the long side edge inclined inward, so as to guide the long side edge into the positioning guide groove on the corresponding side.

[0010] Preferably, the two inner clamping plates are used to clamp the two sides of the middle plate, and the two outer clamping plates are used to clamp the two sides of the assembled metal middle frame of the mobile phone. When the middle plate is clamped, transferred and placed on the placement seat to the predetermined assembly position, the side portion of the middle plate fits with the side surface of the second straightening block in the straightening piece.

Springs A are sleeved on the outside of the two guide rods A, one end of the spring A is fixed to the lower surface of the mounting seat, and the other end is fixed to the bottom wall of the assembly cavity. The side of the second straightening block facing away from the placement seat has a pressurized arc surface A that is squeezed and matched with the short side of the large U-shaped frame, so as to prompt the mounting seat, the first straightening block and the second straightening block to retract vertically downward into the assembly cavity as a whole.

[0014] Preferably, vertically extending slide grooves are provided on the inner walls on both sides of the assembly cavity, and limit blocks are fixed on both sides of the mounting seat. The two limit blocks are slidably mounted in the corresponding slide grooves respectively, and the top surface of the limit block cooperates with the top wall of the slide groove to position the top surface of the mounting seat to a state not higher than the top surface of the assembly table.

[0015] Preferably, a bracket is fixed on the assembly table, and a three-axis moving group is provided on the bracket. A guide seat is provided at the bottom end of the three-axis moving group, and two clamping members are symmetrically arranged below the guide seat. A driving mechanism for driving the two clamping members to move closer to or away from each other is provided on the guide seat. The three-axis moving group includes a first power guide rail, a second power guide rail and a lifting cylinder.

[0016] Preferably, the driving mechanism includes a bidirectional threaded rod, a driving motor and a nut seat. A driving groove is provided under the guide seat. The bidirectional threaded rod is rotatably installed in the driving groove. The driving motor is fixed on one side of the guide seat, and the output shaft is fixedly connected to one end of the bidirectional threaded rod. The two nut seats are respectively slidably installed in the driving groove and are respectively threadedly mounted on both sides of the bidirectional threaded rod. The two clamps are respectively installed at the bottom of the corresponding nut seats.

[0017] Preferably, the outer splint is in an inverted L shape, the two outer splints are respectively fixed at the bottom of the corresponding nut seats, the inner splint is correspondingly installed on the inner side of the outer splint, and slides in contact with the outer splint accordingly, and a guide rod B extending vertically downward is fixed on the two outer splints, and the guide rod B is correspondingly slidably inserted into the guide hole B at the top of the inner splint, and a spring B is provided on the outside of the guide rod B, one end of the spring B is fixed to the outer splint, and the other end is fixed to the top of the inner splint.

[0018] The inner plate has a pressure arc surface B on one side close to the mounting seat. When the long side is squeezed and fitted with the pressure arc surface B, the inner plate can be pushed up. A blocking block is fixed on the inner side of the outer plate. When the inner plate moves to the extreme position, the top of the inner plate contacts the bottom of the blocking block. At this time, a positioning guide groove is formed between the inner surface of the outer plate and the bottom surface of the inner plate.

[0019] The method of using this mobile phone metal frame rapid prototyping processing equipment is as follows:

[0020] Using a straightening member to straighten the outwardly inclined or inwardly inclined long side and guide it into the guide cavity;

[0021] Using the guide cavity to guide the long side into the positioning guide groove;

[0022] Use the positioning guide groove to guide the buckle to align with the slot on the same side.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0024] The present invention arranges a straightening piece on the feeding assembly path of the large U-shaped frame, and uses the straightening piece to directly pre-straighten the inclined long side edge, so as to smoothly guide the long side edge into a positioning guide groove formed by the cooperation of the outer clamping plate and the inner clamping plate. The positioning guide groove is used to position and guide the long side edge so that the buckle can be smoothly inserted into the card slot, thereby eliminating the process of detecting and correcting the long side edge before assembly, realizing rapid assembly and forming of the metal middle frame of the mobile phone, and effectively improving the processing efficiency.

[0025] After the straightening parts straighten the long sides, they are precisely positioned with the positioning guide grooves to reduce the misalignment of the buckles and the slots, ensure the accurate assembly positions of the large U-shaped frame, small U-shaped frame and middle plate, improve the overall assembly accuracy of the metal middle frame of the mobile phone, and reduce the product defective rate caused by assembly errors. The straightening parts can handle the situation where the long sides are tilted inward or outward, and can effectively straighten and guide large U-shaped frames in different deformation states, so that the equipment can adapt to various shape and position errors of the large U-shaped frames, broadening the scope of application of the equipment. The structural design of the equipment enhances the continuity of the assembly process, from component loading, middle plate positioning, long side straightening and guiding to final assembly and molding, each link is closely connected, without the need for frequent manual intervention, reducing the operating steps, reducing the labor intensity of workers, and improving the convenience of production operations.

[0026] The clamping member composed of an outer clamping plate and an inner clamping plate is used for clamping and transferring the middle plate and the assembled mobile phone middle frame, and can also form a positioning guide groove for positioning and guiding the long side edges through structural coordination, thereby achieving multiple goals at one stroke. The clamping member has a design that combines the dual effects of a clamp and a positioning fixture, which simplifies the number of equipment components, reduces equipment manufacturing costs, optimizes production layout, and provides strong support for efficient and high-quality assembly and molding production of mobile phone middle frames.

[0027] The streamlined equipment structure and smaller number of parts reduce the risk of equipment failure. The relatively simple structure of each component makes it easier for maintenance personnel to understand and troubleshoot the problem. When equipment problems occur, they can be repaired quickly, reducing equipment downtime and maintenance costs.

[0028] The present invention utilizes the extrusion cooperation between the long side and the pressure arc surface B to realize the upward movement of the inner clamping plate to form a positioning guide groove, and utilizes the short side of the long side to resist and extrude the pressure arc surface A to push the straightening part as a whole to retract into the assembly cavity to avoid the straightening part from blocking and interfering with the feeding of the long side. Both are linkage settings between structures, and there is no need to set up an additional driving source. The structural space utilization rate is high, the energy consumption of equipment operation is reduced, and it is beneficial to save production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] See also Figure 1-Figure 15 The present invention provides a mobile phone metal frame rapid prototyping processing equipment. The embodiment of the present invention is described below in conjunction with the drawings in the embodiment of the present invention.

[0046] The mobile phone metal frame rapid prototyping processing equipment includes a machine 1, which has an assembly table 11, and U-shaped push racks 2 are respectively arranged on both sides above the assembly table 11. The shapes of the two U-shaped push racks 2 are respectively matched with the large U-shaped frame 01 and the small U-shaped frame 02. A placement seat 12 for positioning and placing a middle plate 04 is provided on the assembly table 11, and the placement seat 12 is located between the two U-shaped push racks 2. Robots 14 are also respectively arranged on both sides of the machine 1, wherein the robot 14 on one side is used to load the large U-shaped frame 01 into the U-shaped push rack 2 on the same side, and the robot 14 on the other side is used to load the small U-shaped frame 02 into the U-shaped push rack 2 on the same side.

[0047] A bracket 13 is fixed on the assembly table 11, and a three-axis moving group 4 is provided on the bracket 13. A guide seat 5 is provided at the bottom end of the three-axis moving group 4. A pair of clamping members 7 are symmetrically provided below the guide seat 5 through a driving mechanism 6 arranged thereon. The driving mechanism 6 is used to drive the two clamping members 7 to move closer to or away from each other to achieve clamping and releasing.

[0048] The two U-shaped push racks 2 are slidably mounted on the assembly table 11. Screw cylinder modules 21 are provided on both sides of the assembly table 11. The moving seats A22 on the two screw cylinder modules 21 are fixed to the U-shaped push racks 2 on the corresponding sides through connecting arms 23. When the large U-shaped frame 01 and the small U-shaped frame 02 are respectively loaded into the U-shaped push racks 2 on both sides, the moving seats A22 thereon are driven to move by the screw cylinder module 21. Under the fixed connection of the connecting arm 23, the moving seats A22 thereon can be driven The U-shaped pusher 2 is translated and adjusted along the length direction of the assembly table 11. When the middle plate 04 is placed on the placement seat 12, the U-shaped pusher 2 on one side is used to push the large U-shaped frame 01 to feed toward the middle plate 04, and the U-shaped pusher 2 on the other side is used to push the small U-shaped frame 02 to feed toward the middle plate 04. Finally, the large U-shaped frame 01 and the small U-shaped frame 02 can be clamped on both sides of the middle plate 04, and the buckles 012 are respectively clamped into the card slots 021, and the overall assembly of the complete mobile phone metal middle frame is completed.

[0049] See also Figure 5-Figure 8 A straightening member 3 is provided on the assembly table 11 on the feeding assembly path of the large U-shaped frame 01. The guiding bevel A321 in the straightening member 3 is used to guide and straighten the long side 011 inclined outwardly, and the guiding bevel B331 in the straightening member 3 is used to guide and straighten the long side 011 inclined inwardly.

[0050] The straightening member 3 consists of a mounting seat 31, a second straightening block 33 and a pair of first straightening blocks 32. The mounting seat 31 is mounted on the assembly table 11, and the second straightening block 33 is mounted on the top of the mounting seat 31. The two first straightening blocks 32 are symmetrically fixed on the mounting seat 31 at both sides of the second straightening block 33. Guide cavities 34 are formed between the two sides of the second straightening block 33 and the two first straightening blocks 32. The two first straightening blocks 32 are both provided with a guiding inclined surface A321 for guiding the long side edge 011 into the guiding cavity 34. The second straightening block 33 has guiding inclined surfaces B331 on both sides for guiding the long side edge 011 into the guiding cavity 34.

[0051] Specifically, when the large U-shaped frame 01 with the long side 011 tilted outward is fed and assembled, Fig. 9 As shown in the figure (the dotted line in the figure is the straightened long side 011), the end of the long side 011 can be guided into the guide cavity 34 by extrusion using the guide slope A321. When the large U-shaped frame 01 with the long side 011 tilted inward is fed and assembled, as shown in the figure, Fig.10As shown (the dotted line in the figure is the long side 011 after straightening), the end slope of the long side 011 can be squeezed and guided into the guide cavity 34 by using the guide slope B331, thereby achieving a pre-straightening effect on the long side 011.

[0052] See also Figure 3 and Figure 4 The clamping member 7 is composed of an outer clamping plate 71 and an inner clamping plate 72 arranged on the inner side of the outer clamping plate 71. The outer clamping plate 71 is in an inverted L shape. The two outer clamping plates 71 are respectively fixed to the bottom of the corresponding nut seat 63, and the inner clamping plate 72 is correspondingly installed on the inner side of the outer clamping plate 71 and slides with the outer clamping plate 71 accordingly. The two inner clamping plates 72 are used to clamp the two sides of the middle plate 04. A guide rod B73 extending vertically downward is fixed on the two outer clamping plates 71. The guide rod B73 is correspondingly slidably inserted in the guide hole B722 at the top of the inner clamping plate 72. A spring B74 is sleeved on the outside of the guide rod B73. One end of the spring B74 is fixed to the outer clamping plate 71, and the other end is fixed to the top of the inner clamping plate 72.

[0053] Under the elastic support of the spring B74, the inner clamping plate 72 moves to the bottom end, and the driving mechanism 6 works to drive the outer clamping plates 71 on both sides to move closer to each other. Fig.11 As shown, the outer clamping plates 71 on both sides synchronously drive the two inner clamping plates 72 to clamp the middle plate 04, and the three-axis moving group 4 works to transfer and place the middle plate 04 on the placement seat 12, and make the side of the middle plate 04 fit with the side surface of the second straightening block 33 to achieve the positioning and placement of the middle plate 04. At this time, the middle plate 04 reaches the predetermined assembly position. At this time, the middle plate 04 corresponds to the height of the card gap 03 on the large U-shaped frame 01 and the small U-shaped frame 02, ensuring that the middle plate 04 can be smoothly inserted into the card gap 03 on the large U-shaped frame 01 and the small U-shaped frame 02.

[0054] After the middle plate 04 is transferred to the predetermined assembly position, the driving mechanism 6 drives the two clamping members 7 to move away from each other until they reach the positioning position. Fig.12 As shown, the inner clamping plates 72 on both sides maintain a sliding fit with the two sides of the middle plate 04. It is worth mentioning that when the clamping member 7 is in the positioning position, the two inner clamping plates 72 do not clamp the middle plate 04, but only fit on both sides of the middle plate 04, which not only plays a positioning effect on the middle plate 04 and prevents the middle plate 04 from shifting forward and backward, but also ensures that the inner clamping plates 72 have the ability to slide.

[0055] like Figure 4 As shown, the inner plate 72 has a pressure arc surface B721 on one side close to the mounting seat 31. When the long side 011 is squeezed and fitted with the pressure arc surface B721, the inner plate 72 can be pushed to move upward. A blocking block 75 is fixed on the inner side of the outer plate 71. When the inner plate 72 moves to the extreme position, the top of the inner plate 72 contacts the bottom of the blocking block 75.

[0056] As the large U-shaped frame 01 continues to advance, the end of the long side 011 will contact and squeeze the compressed arc surface B721 on the inner clamping plate 72, and the inner clamping plate 72 will move upward under pressure. At this time, the spring B74 is elastically compressed until the top of the inner clamping plate 72 contacts the bottom of the stop block 75, and the inner clamping plate 72 moves up to the limit position. Fig.13 and Fig.14 As shown, a positioning guide groove 8 aligned with the guide cavity 34 on the same side is formed between the inner surface of the outer clamping plate 71 and the bottom surface of the inner clamping plate 72. The purpose of aligning the guide cavity 34 with the positioning guide groove 8 is to ensure that the long side 011 can be smoothly aligned and guided into the positioning guide groove 8.

[0057] When the long side 011 is in the positioning guide groove 8, its outer side is in contact with the inner surface of the outer clamping plate 71, its top end is in contact with the bottom end surface of the inner clamping plate 72, and its inner side is clamped on the middle plate 04 (that is, the middle plate 04 is inserted into the clamping seam 03 on the long side 011). The outer clamping plate 71 is used to prevent the long side 011 from tilting outward, and the inner clamping plate 72 is used to prevent the long side 011 from tilting upward. At the same time, the correct assembly position of the long side 011 and the middle plate 04 is ensured to achieve the positioning of the long side 011.

[0058] As the large U-shaped frame 01 and the small U-shaped frame 02 are continuously pushed by the U-shaped pushing rack 2, the positioning guide groove 8 is used to position the long side 011, guiding the buckle 012 to always remain aligned with the slot 021, thereby ensuring that the buckle 012 can be smoothly inserted into the slot 021, thereby realizing the assembly of the large U-shaped frame 01, the small U-shaped frame 02 and the middle plate 04, and completing the assembly and molding of the metal middle frame of the mobile phone.

[0059] At the same time, if Fig.13 As shown, after the metal middle frame of the mobile phone is assembled and formed, the long sides 011 on both sides are respectively fitted with the inner surfaces of the outer clamping plates 71, and the two outer clamping plates 71 are driven to approach each other by the driving mechanism 6, so that the assembled metal middle frame of the mobile phone can be clamped for direct material transfer. In addition, in this process, since the long sides 011 push the inner clamping plate 72 upward, the bottom end of the inner clamping plate 72 is higher than the middle plate 04, and then when the two outer clamping plates 71 are clamped on both sides of the metal middle frame of the mobile phone, the inner clamping plate 72 will not block or interfere with the middle plate 04.

[0060] The method of using this mobile phone metal frame rapid prototyping processing equipment is as follows:

[0061] The straightening member 3 is used to straighten the long side edge 011 inclined outward or inward and guide it into the guide cavity 34;

[0062] The long side 011 is guided into the positioning guide groove 8 by using the guide cavity 34;

[0063] The positioning guide groove 8 is used to guide the buckle 012 to be aligned with the slot 021 on the same side.

[0064] In summary, the present invention sets a straightening component 3 on the feeding assembly path of the large U-shaped frame 01, and uses the straightening component 3 to directly pre-straighten the inclined long side 011, so as to smoothly guide the long side 011 into the positioning guide groove 8 formed by the outer clamping plate 71 and the inner clamping plate 72. The positioning guide groove 8 is used to position and guide the long side 011, so that the buckle 012 can be smoothly inserted into the slot 021, thereby eliminating the process of detecting and correcting the long side 011 before assembly, thereby realizing the rapid assembly and forming of the metal middle frame of the mobile phone, and effectively improving the processing efficiency.

[0065] See also Figure 6 and Figure 7 An assembly cavity 111 is provided on the assembly table 11, and the mounting seat 31 is installed in the assembly cavity 111 in a lifting and sliding manner. Two guide rods A35 fixed on the inner bottom wall of the assembly cavity 111 slide vertically and extend into two guide holes A311 at the bottom of the mounting seat 31 respectively. Springs A36 are sleeved on the outside of the two guide rods A35. One end of the spring A36 is fixed to the lower surface of the mounting seat 31, and the other end is fixed to the inner bottom wall of the assembly cavity 111, so that the mounting seat 31 has the ability to be lifted and slid.

[0066] The second straightening block 33 has a compressed arc surface A332 on the side away from the placement seat 12 that is squeezed and matched with the short side of the large U-shaped frame 01 to cause the mounting seat 31, the first straightening block 32 and the second straightening block 33 to retract vertically downward into the assembly cavity 111 as a whole.

[0067] When the U-shaped pusher 2 pushes the large U-shaped frame 01 to feed for assembly, when the short side of the long side 011 is in contact and squeezed with the compressed arc surface A332, the mounting seat 31 and the first straightening block 32 and the second straightening block 33 thereon are pushed downward until the straightening component 3 is completely retracted into the assembly cavity 111, thereby preventing the straightening component 3 from obstructing the feeding of the U-shaped pusher 2 and the long side 011, thereby ensuring that the long side 011 can be assembled in place.

[0068] Specifically, vertically extending slide grooves 112 are provided on the inner walls on both sides of the assembly cavity 111, and limiting blocks 37 are fixed on both sides of the mounting seat 31. The two limiting blocks 37 are respectively slidably mounted in the corresponding slide grooves 112, and the top surfaces of the limiting blocks 37 are blocked by the inner top walls of the slide grooves 112 to position the top surface of the mounting seat 31 to a state not higher than the top surface of the assembly table 11, so as to prevent the mounting seat 31 from protruding above the top surface of the assembly table 11 and causing obstruction and interference to the feeding of the long side 011.

[0069] like Figure 2As shown, the three-axis moving group 4 includes a first power guide rail 41, a second power guide rail 43 and a lifting cylinder 45. The first power guide rail 41 is installed on the bracket 13. The first power guide rail 41 has a moving seat B42 that can be moved forward and backward. The second power guide rail 43 is installed below the moving seat B42. The second power guide rail 43 has a moving seat C44 that can be adjusted left and right. The lifting cylinder 45 is vertically installed below the moving seat C44, and the guide seat 5 is installed on the end of the telescopic rod of the lifting cylinder 45.

[0070] By working through the first power guide rail 41, the movable seat B42 can drive the guide seat 5, the driving mechanism 6 and the clamping member 7 to be adjusted forward and backward as a whole. By working through the second power guide rail 43, the movable seat C44 can drive the guide seat 5, the driving mechanism 6 and the clamping member 7 to be adjusted left and right as a whole. By working through the extension and retraction of the lifting cylinder 45, the guide seat 5, the driving mechanism 6 and the clamping member 7 can be driven to be raised and lowered, thereby facilitating the transfer of the middle plate 04 and the assembled metal middle frame of the mobile phone.

[0071] Among them, it is worth mentioning that the working principle of the wire cylinder module 21 is consistent with the wire cylinder structure in the prior art. The first power guide rail 41 and the second power guide rail 43 adopt a linear drive structure such as an electric push cylinder, a cylinder or a hydraulic cylinder. The specific structure and working principle of the wire cylinder module 21, the first power guide rail 41 and the second power guide rail 43 will not be described in detail.

[0072] like Figure 3 As shown, the driving mechanism 6 includes a bidirectional threaded rod 61, a driving motor 62 and a nut seat 63. A driving groove 51 is provided below the guide seat 5. The bidirectional threaded rod 61 is rotatably installed in the driving groove 51. The driving motor 62 is fixed on one side of the guide seat 5, and the output shaft is fixedly connected to one end of the bidirectional threaded rod 61. The two nut seats 63 are respectively slidably installed in the driving groove 51 and are respectively threadedly matched on both sides of the bidirectional threaded rod 61. The two clamping members 7 are respectively installed at the bottom of the corresponding nut seats 63.

[0073] By driving the motor 62, its output shaft drives the bidirectional threaded rod 61 to rotate, and the rotating bidirectional threaded rod 61 drives the two nut seats 63 to move closer to or away from each other, thereby driving the clamping parts 7 on both sides to move closer to or away from each other, providing effective drive for clamping and releasing work.

[0074] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
