Description

Technical Field

[0001] This invention relates to the field of mobile phone manufacturing technology, specifically to an auxiliary mechanism for aligning and locking the tail plug of a mobile phone. Background Technology

[0002] The charging port is a crucial component of a mobile phone, typically secured to the phone casing with screws. It usually integrates the charging port. Before tightening, the charging port on the charging port needs to be aligned with the opening on the side wall of the phone casing and inserted into place for proper alignment and assembly. The alignment and tightening of the charging port directly affect the functionality of the charging port. To avoid disassembly from the outside, more and more mobile phone charging ports adopt an internal locking design, where the screw head is located inside the phone casing. After alignment and assembly, the screw on the charging port needs to be tightened from the inside of the phone casing. This structural design means that the alignment and tightening of the charging port is mostly done manually. First, the charging port is held by hand for alignment and assembly, then a screwdriver is used to tighten the screw from the inside of the phone casing. This is prone to scratches due to misalignment, resulting in low yield and low production efficiency. Since the parts of the charging port on both sides of the charging port are mostly coated with adhesive, these parts need to be suspended during hand alignment and assembly to prevent adhesive contamination to other parts of the phone casing. This operation is time-consuming, labor-intensive, and has poor stability, making it prone to defects. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an auxiliary mechanism for mobile phone tail plug alignment and internal locking that can significantly improve production efficiency and yield a high product rate.

[0004] To achieve the above objectives, the technical solution provided by the present invention is an auxiliary mechanism for aligning and locking the tail plug of a mobile phone, comprising:

[0005] A support plate, which extends horizontally in the front-back direction, and the left and right side walls of the support plate are connected to sliding plates that can slide up and down and back and forth.

[0006] A housing positioning plate is fixed parallel to the top of the support plate. The upper surface of the housing positioning plate is provided with upwardly protruding positioning blocks around its perimeter. All the positioning blocks form a receiving cavity for placing the mobile phone housing.

[0007] A tail plug positioning assembly includes a flip frame, an adapter frame, and an adsorption block. The flip frame is arranged parallel above the housing positioning plate. The front end of the flip frame is rotatably mounted between two sliding plates via a first rotating shaft. The first rotating shaft extends horizontally in the left-right direction. The adapter frame is movable back-and-forth and connected to the flip frame. The adsorption block is located below the first rotating shaft. The bottom of the adsorption block is provided with a vacuum adsorption port. The adsorption block is connected to the front end of the adapter frame. The adsorption block includes a first adsorption block for adsorbing the mobile phone tail plug charging port and a second adsorption block for adsorbing the mobile phone tail plug circuit board. The second adsorption block is located on both sides of the first adsorption block and is movable up-and-down and connected to the adapter frame.

[0008] The flipping frame has a first working position and a second working position. When the flipping frame is in the first working position, the adsorption block is located directly above the receiving cavity. When the flipping frame is in the second working position, the adsorption block is located in front of and above the receiving cavity and higher than the first rotation axis. The vacuum adsorption port and the receiving cavity are exposed. The flipping frame changes between the first working position and the second working position by rotating 180° axially through the first rotation axis.

[0009] Preferably, the left and right sidewalls of the support plate are connected to a first slide rail extending horizontally in the front-back direction. A first slider is provided on the first slide rail and a second slider is connected to the side of the first slider away from the first slide rail. A second slide rail is provided inside the second slider and a second slide rail is provided thereto. The second slide rail extends vertically in the up-down direction and is fixedly connected to the surface of the opposite side of the sliding plate.

[0010] Preferably, the projection of the flip frame in the vertical direction is square-shaped. The flip frame includes side plates on the left and right sides and a rear panel. The front ends of the side plates are connected to both sides of the first rotating shaft, and the rear ends of the side plates are connected to the left and right ends of the panel.

[0011] Preferably, the upper surface of the side plate is provided with a third slide rail extending in the front-rear direction, and a matching third slider is provided on the third slide rail. The left and right ends of the adapter frame are connected to the third slider, and a resistance spring is provided between the third slider and the surrounding plate. The two ends of the resistance spring abut against the third slider and the surrounding plate, respectively.

[0012] Preferably, a screwdriver guide plate is connected to the adapter frame, the screwdriver guide plate extends horizontally across the adapter frame in the left-right direction, and the upper surface of the screwdriver guide plate is provided with a downwardly recessed screwdriver guide groove, the screwdriver guide groove being aligned with the screw holes on both sides of the charging port.

[0013] More preferably, a transparent dustproof plate is connected to the adapter frame. The dustproof plate is located below the screwdriver guide plate and extends forward. When the flip frame is in the first working position, the dustproof plate is located directly above the receiving cavity.

[0014] Preferably, the tail plug positioning assembly further includes a left-right movable shield. The shield is in the shape of a door frame and covers the first adsorption block. The vertical plate portion of the shield located on both sides of the first adsorption block is used to block the screw holes on both sides of the charging port in the front-back direction. At any given time, only one side of the vertical plate portion blocks the screw hole.

[0015] Preferably, the first adsorption block is movably connected to the middle position of the front end of the adapter frame, and a pressure sensor for detecting insertion pressure is provided between the first adsorption block and the adapter frame. The second adsorption block is movably connected to the front end of the adapter frame via an oblique cylinder. The oblique movement means that the second adsorption block moves towards the first adsorption block while moving downward, and moves away from the first adsorption block while moving upward.

[0016] Preferably, the auxiliary mechanism for aligning and locking the mobile phone charging port further includes a base plate extending horizontally in the front-back direction and slides movable on the left and right sides above the base plate. The front end of the support plate is rotatably mounted between the slides on both sides via a third rotating shaft. The third rotating shaft extends horizontally in the left-right direction. After the alignment and assembly are completed, the rear end of the support plate is rotated no more than 90° around the third rotating shaft so that the screws can be locked into the screw holes on both sides of the charging port.

[0017] Preferably, the third rotating shaft is located below and behind the first rotating shaft.

[0018] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0019] 1. When the flip frame is in the first working position, since the adsorption block is located directly above the receiving cavity, the mobile phone tail plug adsorbed by the adsorption block can be accurately inserted into the mobile phone shell in the receiving cavity by sliding the sliding plate up and down and back and forth, so as to achieve alignment and assembly without the need for manual intervention in the alignment and assembly operation, which can greatly improve production efficiency.

[0020] 2. During insertion, the adapter can buffer the impact by moving back and forth to avoid scratches, and the second suction block can lift the circuit board by moving up and down to avoid adhesive contamination, resulting in a high yield rate.

[0021] 3. When the flip frame is flipped to the second working position, since the adsorption block is located in front of and above the receiving cavity and is higher than the first rotating axis, and the vacuum adsorption port and the receiving cavity are exposed, it is also convenient to load and unload the mobile phone tail plug and the mobile phone casing.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more readily understood by those skilled in the art.

[0032] like Figures 1 to 10As shown, the auxiliary mechanism for aligning and locking the mobile phone tail plug provided by the present invention includes: a support plate 10, a housing positioning plate 20, and a tail plug positioning assembly 30. The support plate 10 is located behind the operator and extends horizontally in the front-to-back direction. The left and right side walls of the support plate 10 are connected to sliding plates 40 that can slide up and down and back and forth. The housing positioning plate 20 is fixed parallel above the support plate 10. The upper surface of the housing positioning plate 20 is provided with upwardly protruding positioning blocks 21 around its perimeter, and all positioning blocks 21 form a receiving cavity 22 for placing the mobile phone housing 1. The tail plug positioning assembly 30 includes a flip frame, an adapter frame 32, and an adsorption block. The flip frame is parallel above the housing positioning plate 20. The front end of the flip frame is rotatably mounted between two sliding plates 40 via a first rotating shaft 311, which extends horizontally in the left-to-right direction. The adapter frame 32 is movable back and forth within the flip frame. The adsorption block is located on the first rotating shaft 311. Below, the bottom of the adsorption block is provided with a vacuum adsorption port 333. The adsorption block is connected to the front end of the adapter frame 32. The adsorption block includes a first adsorption block 331 for adsorbing the charging port 3 of the mobile phone tail plug 2 and a second adsorption block 332 for adsorbing the circuit board 4 of the mobile phone tail plug 2 (the circuit board 4 is a flexible circuit board and is located on the left and right sides of the charging port 3 and extends in the front and back direction). The second adsorption block 332 is located on both sides of the first adsorption block 331. The second adsorption block 332 is movably connected to the adapter frame 32. The flip frame has a first working position and a second working position. When the flip frame is in the first working position, all adsorption blocks are located directly above the receiving cavity 22. When the flip frame is in the second working position, all adsorption blocks are located in front of and above the receiving cavity 22 and higher than the first rotation axis 311. The vacuum adsorption port 333 and the receiving cavity 22 are exposed. The flip frame changes between the first working position and the second working position by rotating axially by 180° on the first rotation axis.

[0033] The advantage of this setting is that:

[0034] 1. When the flip frame is in the first working position, since the adsorption block is located directly above the receiving cavity, the mobile phone tail plug adsorbed by the adsorption block can be accurately inserted into the mobile phone shell in the receiving cavity by sliding the sliding plate up and down and back and forth, so as to achieve alignment and assembly without the need for manual intervention in the alignment and assembly operation, which can greatly improve production efficiency.

[0035] 2. During insertion, the adapter can buffer the impact by moving back and forth to avoid scratches, and the second suction block can lift the circuit board by moving up and down to avoid adhesive contamination, resulting in a high yield rate.

[0036] 3. When the flip frame is flipped to the second working position, since the adsorption block is located in front of and above the receiving cavity and is higher than the first rotating axis, and the vacuum adsorption port and the receiving cavity are exposed, it is also convenient to load and unload the mobile phone tail plug and the mobile phone casing.

[0037] To enable the sliding plate 40 to slide up and down and back and forth, in this embodiment, the left and right sidewalls of the support plate 10 are connected to a first slide rail 11 extending horizontally in the back and forth direction. A first slider 12 is provided on the first slide rail 11 to match it. A second slider 13 is connected to the side of the first slider 12 away from the first slide rail 11. A second slide rail 14 is inserted into the second slider 13 to match it. The second slide rail 14 extends vertically in the up and down direction and is fixedly connected to the surfaces of the two sliding plates 40 facing each other. The bottom of the support plate 10... The unit is provided with a first drive unit 15 for driving the sliding plate 40 to slide back and forth and a second drive unit 16 for driving the sliding plate 40 to slide up and down. The first drive unit 15 includes a first motor 151, a first lead screw pair 152, a bottom slide rail 153, and a bottom slider 154. The second drive unit 16 includes a motor base 161, a second motor 162, a second lead screw pair, and a second slide rail pair 163. Specifically, the first motor 151 is connected to the lower surface of the support plate 10, and the first lead screw pair 152 is located below the support plate 10 and... A bottom slide rail 153 is connected to the output end of the first motor 151 and is connected to the lower surface of the support plate 10, extending in the front-to-back direction. A bottom slider 154 is slidably mounted on the bottom slide rail 153 and connected to the nut in the first lead screw assembly 152. A motor base 161 is located below the support plate 10 and is fixedly connected to the bottom slider 153. A second slide rail assembly 163 extends vertically in the up-down direction. The slide rails of the second slide rail assembly 163 are connected to the left and right sides of the motor base 161, and the sliders of the second slide rail assembly 163 are connected to the sliding... On the surface of the lower end of the plate 40 facing each other, the second motor 162 is fixed inside the motor base 161. The output end of the second motor 162 is connected to the slider of the second slide rail pair 163 through the second lead screw pair. When the first motor 151 is activated, it can drive the bottom slider 153 to slide back and forth through the first lead screw pair 152, thereby causing the motor base 161 and the sliding plate 40 to slide back and forth. When the second motor 162 is activated, it can drive the slider of the second slide rail pair to slide up and down through the second lead screw pair, thereby causing the sliding plate 40 to slide up and down.

[0038] For ease of setup and center of gravity adjustment, in this embodiment, the projection of the sliding plate 40 in the left-right direction is an inverted L-shape. The upper end of the sliding plate 40 extends forward horizontally to form a free end 41. The first rotating shaft 311 is rotatably mounted on the free end 41. Simultaneously, a third motor 42 for driving the first rotating shaft 311 is connected to the outer side of one side of the free end 41. The third motor 42 is connected to the end of the first rotating shaft 311 via a coupling 421. To detect the rotation angle and simplify the structure, a detection block 312 is connected to the end of the first rotating shaft 311 away from the third motor 42. The detection block 312 is located on the outside of the free end 41 and detects... One end of the block 312 is connected to the first rotating shaft 311, and the other end extends along the radial direction of the first rotating shaft 311. A magnet is embedded in the surface of the detection block 312 facing the free end 41. Two parallel detection grooves 411 are provided on the surface of the free end 41 facing the detection block 312. These two detection grooves 411 are symmetrically distributed on both sides of the first rotating shaft 311. Sensors are embedded in these two detection grooves 411. When the magnet on the detection block 312 triggers the sensor in the two detection grooves 411 once, it indicates that the first rotating shaft 311 has rotated 180° along its axial direction. In this embodiment, the detection grooves 411 extend vertically in the up-down direction.

[0039] To facilitate digital management of the production line, the back of the mobile phone casing 1 is usually marked with an identification code. When aligning and assembling the mobile phone tail plug 2 and performing internal locking operations, it is necessary to scan the code to confirm the mobile phone casing 1. Therefore, in this embodiment, an inspection window 23 is provided in the middle of the casing positioning plate 20, and a barcode scanner (not shown in the figure) is connected to the bottom of the casing positioning plate 20. The barcode scanner's scanning port is aligned with the inspection window 23.

[0040] In this embodiment, the projection of the flip frame in the vertical direction is U-shaped. The flip frame includes side plates 313 on the left and right sides and a rear enclosure plate 314. The front ends of the side plates 313 are connected to the left and right sides of the first rotating shaft 311, and the rear ends of the side plates 313 are connected to the left and right ends of the enclosure plate 314. To facilitate the forward and backward sliding of the adapter frame 32, the upper surface of the side plates 313 is provided with a third slide rail extending in the forward and backward direction. A matching third slider 316 is provided on the third slide rail, and the left and right ends of the adapter frame 32 are connected to the third slider 316. To buffer the insertion of the charging port 3 and prevent scratches caused by excessive impact, a resistance spring 317 is further provided between the third slider 316 and the surrounding plate 314. The two ends of the resistance spring 317 abut against the third slider 316 and the surrounding plate 314 respectively. To detect the total insertion force (buffering force), a pointer plate 319 extending backward is provided on the third slider 316 and a scale 318 is provided on the surrounding plate 314. When the third slider 316 moves back and forth, the magnitude of the insertion force can be directly read from the position of the pointer plate 319 on the scale 318.

[0041] To facilitate the alignment and guidance of the screwdriver, in this embodiment, a screwdriver guide plate 321 is connected to the adapter frame 32. The screwdriver guide plate 321 extends horizontally across the adapter frame 32 in the left-right direction. The upper surface of the screwdriver guide plate 321 is provided with a downwardly recessed screwdriver guide groove 322. The screwdriver guide groove 322 is aligned with the screw holes on both sides of the charging port 3. To prevent dust, impurities, etc. carried by the screwdriver from falling into the phone casing 1 when it moves in and out, a transparent dustproof plate 323 is further connected to the adapter frame 32. The dustproof plate 323 is located below the screwdriver guide plate 321 and extends forward. When the flip frame is in the first working position, the dustproof plate 323 is located directly above the receiving cavity 22.

[0042] Since there are screw holes on both sides of the charging port 3, in order to prevent fooling, in this embodiment, the tail plug positioning assembly 30 also includes a left and right movable shield 34. The shield 34 is in the shape of a door frame and covers the first adsorption block 331. The vertical plate portion 341 of the shield 34 on both sides of the first adsorption block 331 is used to block the screw holes on both sides of the charging port 3 in the front-back direction. At any time, only one side of the vertical plate portion 341 blocks its corresponding screw hole. In order to realize the left and right movement of the shield 34, the tail plug positioning assembly 30 further includes a drive cylinder 342 for driving the shield 34 to move left and right and a slide rail pair 343 for guiding the left and right movement of the shield 34. The drive cylinder 342 and the slide rail pair 343 are both directly or indirectly fixed on the milled plane at the end of the first rotating shaft 311.

[0043] In this embodiment, the first adsorption block 331 is movably connected to the middle position of the front end of the adapter frame 32. A pressure sensor 334 for detecting the insertion pressure of the charging port 3 is provided between the first adsorption block 331 and the adapter frame 32. The second adsorption block 332 is movably connected to the front end of the adapter frame 32 via an oblique cylinder 335. This oblique movement means that the second adsorption block 332 moves towards the first adsorption block 331 while moving downward, and moves away from the first adsorption block 331 while moving upward. This oblique movement is to avoid tearing the circuit board 4 and to minimize the load on the oblique cylinder 335. The angle between the direction of the oblique movement and the horizontal plane is preferably 40-50°. In this embodiment, the angle is 45°. Meanwhile, the oblique cylinder 335 includes a cylinder body 336 and a cylinder rod 337. The cylinder body 336 is connected to the adapter frame 32 and is set at an angle. The end of the cylinder rod 337 is connected to the second adsorption block 332 through a connecting plate 338. A buffer spring 339 is also provided between the connecting plate 338 and the adapter frame 32. The two ends of the buffer spring 339 abut against the connecting plate 338 and the adapter frame 32 respectively. The buffer spring 339 is used to slow down the downward movement speed of the second adsorption block 332 to achieve smooth adhesion.

[0044] Since the screwdriver can only magnetically attract screws through its tip, when the screw is inserted into the screw hole horizontally, the screw tip tends to droop due to gravity, making it difficult to insert accurately and requiring multiple adjustments. This can easily cause scratches on both sides of the charging port 3. To solve this problem, in this embodiment, the auxiliary mechanism for aligning and locking the phone's tail plug also includes a base plate 50 extending horizontally in the front-back direction and slides 51 that are movably disposed on the left and right sides above the base plate 50. The front end of the support plate 10 is rotatably mounted between the slides 51 on both sides via a second rotating shaft 52. The second rotating shaft 52 extends horizontally in the left and right directions. Extending horizontally, after the mobile phone tail plug 2 and the mobile phone casing 1 are aligned and assembled, the rear end of the support plate 10 is rotated around the second rotating axis 52 by no more than 90° (in this embodiment, the rotation angle is 80°), adjusting the insertion direction of the screwdriver from horizontal to vertical tilt, so that the screw magnetically attracted at the end of the screwdriver is closer to the insertion direction of the screwdriver, so as to achieve more accurate insertion and facilitate the screw to be locked into the screw holes on both sides of the charging port 3. By rotating the support plate 10, the exposure of the screw holes on both sides of the charging port 3 can also be relatively increased, making it easier for the human eye to observe and for manual control of the screwdriver's internal tightening operation.

[0045] To facilitate the flipping and forward / backward movement of the support plate 10, the second rotating shaft 52 is located below and behind the first rotating shaft 311. Meanwhile, the base plate 50 is also provided with a slide motor 53 and a slide screw pair 54 for driving the slide table 51 to move forward and backward, as well as a slide rail pair 55 for guiding the forward and backward movement of the slide table 51. The outer side of the slide table 51 is also connected to a support plate rotating motor 56 for driving the second rotating shaft 52 to rotate.

[0046] To prevent the second drive unit 16 at the bottom of the support plate 10 from interfering with the base plate 50 when the support plate 10 is flipped, the base plate 50 is further provided with a clearance groove 57 for avoiding the second drive unit 16.

[0047] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
