Description

Technical Field

[0001] This utility model relates to the field of automated mobile phone assembly, and in particular to a positioning fixture for mobile phone assembly. Background Technology

[0002] In the field of existing mobile phone automated assembly technology, pneumatic suction cups are usually used to adsorb the back panel of the mobile phone and position it in the assembly fixture, and a robotic arm is used to perform the precision assembly of components such as camera modules and batteries.

[0003] However, after the components are installed in the backplate, the surface becomes less flat due to the protrusions of multiple components of different sizes, which prevents the vacuum adsorption surface of the suction cup from forming an effective sealing contact with the backplate. This technical defect directly causes the assembled backplate to remain in the fixture, requiring manual intervention for transfer, which reduces the production line cycle efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture for mobile phone assembly, which can automatically transfer and complete the installation of the back plate of the parts.

[0005] The technical solution adopted by the positioning tooling for mobile phone assembly disclosed in this utility model is:

[0006] The system includes a workbench equipped with a loading mechanism, a positioning mechanism, a drive assembly, and a propulsion mechanism. The positioning mechanism has multiple first positioning blocks slidably connected to it, arranged around a center, forming a positioning area between the blocks. A turntable is rotatably connected to the drive assembly, and the turntable has multiple clamps arranged around a center. The workbench sequentially includes a loading area, multiple assembly stations, and a unloading area. The clamps sequentially pass through the loading area, assembly stations, and unloading area. The positioning mechanism is located within the loading area. Each clamp includes a base plate and a connecting seat. The base plate is placed on the turntable, and the base plate has multiple first positioning blocks arranged around a center. A first limiting block and a second limiting block are provided, forming a clamping area between the first limiting block and the second limiting block. The connecting seat is connected to the turntable, and a reset component is slidably connected to the connecting seat. The first limiting block passes through the base plate and the turntable in sequence and is connected to the reset component. Two unlocking cylinders are provided on the worktable, located in the loading area and unloading area respectively. The output shaft of the unlocking cylinder touches the adjacent reset component. The pushing mechanism is located above the turntable, and a pushing cylinder is provided on the pushing mechanism. A pushing rod is fixedly connected to the output shaft of the pushing cylinder, and the pushing cylinder pushes the pushing rod closer to the unloading area.

[0007] As a preferred embodiment, the workbench is provided with a support, the propulsion mechanism includes a connecting rod, the connecting rod is fixedly connected to the support, a second lifting cylinder is fixedly connected to the connecting rod, and the output shaft of the second lifting cylinder is fixedly connected to the propulsion cylinder.

[0008] As a preferred embodiment, the reset assembly includes a connecting plate and a lever. A slide rod extends from the connecting plate and is slidably connected to a connecting seat. A spring is sleeved on the outer side of the slide rod, and the two ends of the spring respectively abut against the end of the slide rod and the connecting seat. The lever is right-angled, and the middle part of the lever is rotatably connected to the connecting seat. One end of the lever abuts against the connecting plate, and the output shaft of the unlocking cylinder abuts against the other end of the lever.

[0009] As a preferred embodiment, the positioning mechanism includes a positioning seat, in which three positioning cylinders are fixedly connected. A first positioning block passes through the positioning seat and is connected to the output shaft of the positioning cylinder. A second positioning block is fixedly connected to the positioning seat, and multiple first and second positioning blocks are located in four directions on the positioning seat.

[0010] As a preferred embodiment, the feeding mechanism includes a lead screw device and a feeding conveyor belt. The lead screw device is fixedly connected to the bracket, and a sliding plate is slidably connected to the lead screw device. A first lifting cylinder is fixedly connected to the sliding plate, and a suction cup frame is fixedly connected to the output shaft of the first lifting cylinder. A first suction cup and a second suction cup are fixedly connected to the suction cup frame. The feeding conveyor belt is placed on the worktable, and the top of the feeding conveyor belt, the top of the positioning seat, and the top of the base plate are all flush.

[0011] As a preferred embodiment, the workbench is equipped with a feeding conveyor belt, one end of which is located in the feeding area, and the top of the feeding conveyor belt is flush with the top of the base plate.

[0012] The beneficial effects of the positioning fixture for mobile phone assembly disclosed in this utility model are:

[0013] The back panel to be assembled is placed in the positioning area by the feeding mechanism. The positioning mechanism drives the first positioning block to slide towards the center. After the first positioning block pushes the back panel to the designated position in the positioning area, the first positioning block slides back to its original position.

[0014] The output shaft of the unlocking cylinder near the loading area rises, pushing the reset component to slide a certain distance on the connecting seat, so that the first limit block moves away from the second limit block; at this time, the loading mechanism transfers the back plate that has completed positioning to the clamping area; subsequently, the output shaft of the unlocking cylinder descends, and the reset component slides and resets on the connecting seat, so that the first limit block and the second limit block clamp the back plate together;

[0015] The drive component drives the turntable to rotate, which in turn drives the clamp holding the back plate to pass through each assembly station in sequence. The external automated assembly equipment in the assembly station installs the parts onto the back plate.

[0016] After the backplate with the installed components is moved to the unloading area, the output shaft of the unlocking cylinder near the unloading area rises, pushing the reset component to slide, causing the first and second limit blocks to release the backplate. Subsequently, the output shaft of the push cylinder pushes the push rod to touch the backplate, pushing it into the unloading area to complete the unloading and transfer of the backplate. Finally, the output shaft of the push cylinder pulls the push rod to reset, thus completing the automatic transfer process. Attached Figure Description

[0024] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0025] Please refer to Figure 1 and Figure 2 .

[0026] The present invention discloses a positioning fixture for mobile phone assembly, including a worktable 1.

[0027] The workbench 1 is equipped with a feeding mechanism 2, a positioning mechanism 3, a drive assembly 4, and a propulsion mechanism 6;

[0028] The top of the workbench 1 is provided with a support 11. The feeding mechanism 2 includes a lead screw device 21 and a feeding conveyor belt 23. The lead screw device 21 is fixedly connected to the support 11. The lead screw device 21 is arranged horizontally. A slide plate 211 is slidably connected to the lead screw device 21. A first lifting cylinder 212 is fixedly connected to the slide plate 211. A suction cup frame 22 is fixedly connected to the output shaft of the first lifting cylinder 212. A first suction cup 221 and a second suction cup 222 are fixedly connected to the suction cup frame 22.

[0029] Furthermore, the feeding conveyor belt 23 is placed on the worktable 1, and the end of the feeding conveyor belt 23 is located below the lead screw device 21.

[0030] In this embodiment, the back panel is preferably covered with a protective film on the back and all four sides. The protective film can prevent the back panel from being scratched when installing parts. The protective film will be removed when the whole machine parts are assembled and packaged.

[0031] Please refer to Figures 1-3 .

[0032] The positioning mechanism 3 includes a positioning seat 31, which is placed on the top of the workbench 1. The top of the feeding conveyor belt 23 is flush with the top of the positioning seat 31. Three positioning cylinders 32 are fixedly connected inside the positioning seat 31, and the output shaft of the positioning cylinders 32 is fixedly connected to a mounting plate. Multiple first positioning blocks 321 arranged around the center are slidably connected on the positioning mechanism 3. In this embodiment, it is preferred that there are three first positioning blocks 321, and the three first positioning blocks 321 correspond to three positioning cylinders 32.

[0033] Furthermore, the positioning seat 31 has three first through slots 311. The first positioning block 321 is tunably connected to the mounting plate of the positioning cylinder 32 through the first through slots 311. The positioning seat 31 is tunably connected to a second positioning block 312. The positions of the first positioning block 321 and the second positioning block 312 can be adjusted according to different models of back plates, so that the fixture 5 can be adapted to assemble more models of mobile phones. The three first positioning blocks 321 and the second positioning block 312 are located in four directions on the positioning seat 31, and a positioning area is formed between the three first positioning blocks 321 and the second positioning block 312. The distance between the feeding conveyor belt 23 and the positioning area is equal to the distance between the first suction cup 221 and the second suction cup 222.

[0034] The backplate of the part to be installed is transported near the bottom of the first suction cup 221 via the feeding conveyor belt 23. The output shaft of the first lifting cylinder 212 pushes the suction cup frame 22 down, so that the first suction cup 221 contacts and adsorbs the backplate. The output shaft of the first lifting cylinder 212 pulls the suction cup frame 22 up. The slide plate 211 is driven to slide a certain distance by the screw device 21, so that the first suction cup 221 moves to the top of the positioning area. The output shaft of the first lifting cylinder 212 pushes the suction cup frame 22 down, so that the first suction cup 221 places the backplate in the positioning area. The screw device 21 and the first lifting cylinder 212 drive the suction cup frame 22 to reset.

[0035] The positioning cylinder 32 pushes the first positioning block 321 to slide within the first through groove 311, causing the three first positioning blocks 321 to slide toward the center of the positioning seat 31, thereby reducing the size of the positioning area. When a back plate is placed in the positioning area, the three first positioning blocks 321 respectively abut against the three sides of the back plate, moving the back plate to the center of the positioning seat 31, so that the fourth side of the back plate abuts against the second positioning block 312, thereby positioning the Y-axis position of the back plate. After the positioning of the back plate is completed, the positioning cylinder 32 pulls the first positioning block 321 to slide back to its original position.

[0036] Please refer to Figure 1 , Figure 2 and Figure 4 .

[0037] The drive assembly 4 includes a gearbox and a drive motor. The gearbox is located on the top of the worktable 1, and the drive motor is located at the bottom of the worktable 1. The output shaft of the drive motor is connected to the gearbox, and the output shaft of the drive motor drives the gearbox to run. A turntable 41 is rotatably connected to the drive assembly 4. The center of the turntable 41 is fixedly connected to the output shaft of the gearbox, and the output shaft of the gearbox drives the turntable 41 to rotate.

[0038] The top of the turntable 41 is provided with a plurality of clamps 5 arranged around the center. The clamps 5 are close to the edge of the turntable 41. In this embodiment, it is preferred that there are eight clamps 5, with the turntable 41 as the center, and the included angle between two adjacent clamps 5 is 45°.

[0039] Furthermore, the workbench 1 is sequentially provided with a loading area, multiple assembly stations, and a unloading area. In this embodiment, it is preferred that there are six assembly stations, and each assembly station is equipped with external automatic assembly equipment for different installation processes. The loading area is close to the unloading area. Six clamps 5 are located in the six assembly stations, and the other two clamps 5 are located in the loading area and the unloading area, respectively. The turntable 41 drives each clamp 5 to move sequentially through the loading area, multiple assembly stations, and the unloading area. The positioning seat 31 is located in the loading area, between the loading conveyor belt 23 and the turntable 41. The distance between the clamp 5 and the positioning area is equal to the distance between the first suction cup 221 and the second suction cup 222.

[0040] Please refer to Figure 1 , Figure 5 and Figure 6 .

[0041] The clamp 5 includes a base plate 51 and a connecting seat 52; the base plate 51 is placed on the top of the turntable 41, and the top of the base plate 51 is flush with the top of the positioning seat 31. The base plate 51 is provided with a first limiting block 531 and a second limiting block 512, and a clamping area is formed between the first limiting block 531 and the second limiting block 512.

[0042] Furthermore, the connecting base 52 is fixedly connected to the bottom of the turntable 41, and a reset component 53 is slidably connected to the connecting base 52;

[0043] Furthermore, the reset assembly 53 includes a connecting plate 532 and a lever 535. Two parallel sliding rods 533 extend from the connecting plate 532 and are slidably connected to the connecting seat 52. A spring 534 is sleeved on the outer side of the sliding rod 533. The two ends of the spring 534 respectively abut against the end of the sliding rod 533 and the connecting seat 52. The spring 534 pushes the sliding rod 533 to slide on the connecting seat 52, causing the connecting plate 532 to move closer to the connecting seat 52. A notch is provided on the connecting seat 52, located between the two sliding rods 533. In this embodiment, the lever 535 is preferably right-angled and placed in the notch. The middle part of the lever 535 is rotatably connected to the connecting seat 52, and one end of the lever 535 abuts against the connecting plate 532.

[0044] Furthermore, a second through slot 511 is provided on the base plate 51, which passes through the base plate 51 and the turntable 41 in sequence. The first limiting block 531 is tunably connected to the base plate 51. The first limiting block 531 passes through the second through slot 511 and the turntable 41 in sequence and is tunably connected to the connecting plate 532 of the reset assembly 53. The positions of the first limiting block 531 and the second limiting block 512 can be adjusted according to different models of back plates, so that the fixture 5 can be adapted to assemble more models of mobile phones.

[0045] The workbench 1 is equipped with two unlocking cylinders 12, which are located in the loading area and unloading area respectively. The output shaft of the unlocking cylinder 12 touches the adjacent reset component 53, and the output shaft of the unlocking cylinder 12 touches the other end of the lever 535.

[0046] The output shaft of the unlocking cylinder 12 pushes the other end of the lever 535, causing the lever 535 to rotate a certain angle on the connecting seat 52, so that one end of the lever 535 touches the connecting plate 532, pushing the slide bar 533 of the connecting plate 532 to slide on the connecting seat 52 and compressing the spring 534. The connecting plate 532 drives the first limiting block 531 to slide in the second through groove 511, so that the first limiting block 531 moves away from the second limiting block 512, opening the width of the clamping area, thereby releasing the clamping of the back plate;

[0047] When a backplate is placed in the clamping area, the output shaft of the unlocking cylinder 12 is reset, the lever 535 loses the thrust of the unlocking cylinder 12, the spring 534 pushes the slide rod 533 of the connecting plate 532 to slide and reset on the connecting seat 52, the connecting plate 532 pushes the lever 535 to rotate and reset on the connecting seat 52, the first limiting block 531 slides in the second through groove 511 and pushes one side of the backplate, so that the backplate approaches and touches the second limiting block 512, thereby positioning the X-axis position of the backplate;

[0048] When the feeding mechanism 2 drives the first suction cup 221 to reset and adsorb the next back plate, the second suction cup 222 contacts and adsorbs the back plate that has completed positioning in the positioning area; the clamp 5 in the feeding area opens the clamping area, and when the feeding mechanism 2 drives the first suction cup 221 to place the adsorbed back plate in the positioning area, the second suction cup 222 simultaneously places the back plate that has completed positioning in the clamping area. The clamp 5 clamps the back plate, and the feeding mechanism 2 drives the first suction cup 221 and the second suction cup 222 to reset, so that the first suction cup 221 adsorbs the next back plate on the conveyor belt, and the second suction cup 222 adsorbs the next back plate that has completed positioning in the positioning area. The turntable 41 rotates 45°, so that the next empty clamp 5 enters the feeding area.

[0049] When the turntable 41 rotates 45° each time, the back plate inside the fixture 5 enters each assembly station in sequence, and the external automatic assembly equipment automatically installs the parts on the back plate until the back plate enters the unloading area.

[0050] Please refer to Figure 1 and Figure 7 .

[0051] The propulsion mechanism 6 includes a connecting rod 61, which is fixedly connected to the bracket 11. The propulsion mechanism 6 is located above the turntable 41. A second lifting cylinder 611 is fixedly connected to the connecting rod 61. The propulsion mechanism 6 is equipped with a propulsion cylinder 62. The output shaft of the second lifting cylinder 611 is fixedly connected to the propulsion cylinder 62. A propulsion rod 621 is fixedly connected to the output shaft of the propulsion cylinder 62. The workbench 1 is equipped with a feeding conveyor belt 7. One end of the feeding conveyor belt 7 is located in the feeding area. The top of the feeding conveyor belt 7 is flush with the top of the base plate 51.

[0052] When the backplate with assembled components enters the unloading area, the clamping area releases the backplate, and the second lifting cylinder 611 pushes the propulsion cylinder 62 down, causing the propulsion rod 621 to contact the base plate 51. The propulsion cylinder 62 pushes the propulsion rod 621 towards the unloading area, causing the propulsion rod 621 to push the backplate above the unloading conveyor belt 7, completing the unloading and transfer of the backplate. The second lifting cylinder 611 and the propulsion cylinder 62 pull the propulsion rod 621 back to its original position, waiting for the next backplate with assembled components.

[0053] This utility model provides a positioning fixture for assembling mobile phones. The back panel to be assembled is placed in the positioning area by the feeding mechanism. The positioning mechanism drives the first positioning block to slide towards the center. After the first positioning block pushes the back panel to a designated position in the positioning area, the first positioning block slides back to its original position.

[0054] The output shaft of the unlocking cylinder near the loading area rises, pushing the reset component to slide a certain distance on the connecting seat, so that the first limit block moves away from the second limit block; at this time, the loading mechanism transfers the back plate that has completed positioning to the clamping area; subsequently, the output shaft of the unlocking cylinder descends, and the reset component slides and resets on the connecting seat, so that the first limit block and the second limit block clamp the back plate together;

[0055] The drive component drives the turntable to rotate, which in turn drives the clamp holding the back plate to pass through each assembly station in sequence. The external automated assembly equipment in the assembly station installs the parts onto the back plate.

[0056] After the backplate with the installed components is moved to the unloading area, the output shaft of the unlocking cylinder near the unloading area rises, pushing the reset component to slide, causing the first and second limit blocks to release the backplate. Subsequently, the output shaft of the push cylinder pushes the push rod to touch the backplate, pushing it into the unloading area to complete the unloading and transfer of the backplate. Finally, the output shaft of the push cylinder pulls the push rod to reset, thus completing the automatic transfer process.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
