Before welding, the phone needs to be fed, the copper sheets need to be loaded and positioned, the positioned copper sheets need to be transferred and pressed onto the phone, and a welding mechanism is used to weld the phone and copper sheets. Existing technology does not automate the feeding, transfer, copper sheet loading and positioning, transfer and pressing, welding, and unloading processes of the phone by employing a feeding mechanism, a transfer mechanism, a copper sheet loading and positioning mechanism, a transfer and pressing mechanism, a welding mechanism, and an unloading mechanism, thus improving welding efficiency and reducing labor costs. By using a transfer and pressing mechanism, the position of the copper sheets is transferred and pressed and fixed, preventing the copper sheets from shifting during welding and improving accuracy.

The feeding mechanism 10, the transfer and pressing mechanism 40, the welding mechanism 50 and the discharging mechanism 60 are distributed sequentially along the transfer direction of the transfer mechanism 20.

[0020] The feeding mechanism 10 feeds the mobile phone to be welded onto the transfer mechanism, which moves the mobile phone. The copper sheet feeding and positioning mechanism 30 feeds and positions the copper sheet. The transfer and pressing mechanism 40 transfers and presses the copper sheet into the mobile phone on the transfer mechanism 20. The welding mechanism 50 welds the copper sheet to the middle frame of the mobile phone. The discharging mechanism 60 discharges the welded mobile phone from the transfer mechanism 20.

[0021] By employing a feeding mechanism 10, a transfer mechanism 20, a copper sheet feeding and positioning mechanism 30, a transfer and pressing mechanism 40, a welding mechanism 50, and a discharging mechanism 60, the feeding, transfer, copper sheet feeding and positioning, copper sheet transfer and pressing, copper sheet welding, and mobile phone discharging of the mobile phone are automated, improving welding efficiency and reducing labor costs. The use of the transfer and pressing mechanism 40 enables the position transfer and pressing and fixing of the copper sheet, preventing the copper sheet from shifting during the welding process and improving accuracy.

[0022] Both the feeding mechanism 10 and the discharging mechanism 60 include a longitudinal material transfer drive assembly 11, a vertical material transfer drive assembly 12, and a material pick-up nozzle 13. The vertical material transfer drive assembly 12 is installed at the output end of the longitudinal material transfer drive assembly 11, and the material pick-up nozzle 13 is installed at the output end of the vertical material transfer drive assembly 12.

[0023] The position of the material-picking nozzle 13 is moved by using the longitudinal material transfer drive component 11 and the vertical material transfer drive component 12, thus meeting the position movement requirements.

[0024] The copper sheet feeding and positioning mechanism 30, the transfer and pressing mechanism 40, and the welding mechanism 50 are all in two sets. The two sets of copper sheet feeding and positioning mechanisms 30, transfer and pressing mechanisms 40, and welding mechanisms 50 are distributed on both sides of the transfer mechanism 20. The two sets of copper sheet feeding and positioning mechanisms 30, transfer and pressing mechanisms 40, and welding mechanisms 50 are located between the feeding mechanism 10 and the discharging mechanism 60. The copper sheet feeding is achieved by using two sets of braided belt feeders corresponding to the two sets of copper sheet feeding and positioning mechanisms 30, which improves the work efficiency.

[0025] The transfer mechanism 20 includes a transfer drive assembly 21, a flip drive assembly 22 for adjusting the front and side flip angles of the mobile phone, and a fixture 23 for placing the mobile phone, wherein: The flip drive assembly 22 is installed at the output end of the transfer drive assembly 21. The flip drive assembly 22 includes a support 221, a flip drive device 222, and a flip rod 223. The support 221 is installed at the output end of the transfer drive assembly 21. The flip drive device 222 is installed on the support 221. The flip rod 223 is installed at the output end of the flip drive device 222. The flip rod 223 is rotatably located on the support 221. The fixture seat 23 is detachably installed on the flip rod 223.

[0026] Both the fixture base 23 and the flipping rod 223 are provided with threaded holes. The fixture base 23 and the flipping rod 223 can be detached and installed by means of bolts passing through the threaded holes on the fixture base 23 and the flipping rod 223.

[0027] The transfer drive assembly 21 drives the flip drive assembly 22 and the fixture seat 23 to move their positions, thereby moving the mobile phone on the fixture seat 23 to meet the position requirements during mobile phone assembly. The flip drive device 222 drives the flip rod 223 to rotate. The fixture seat 23 is detachably mounted on the flip rod 223. The rotation of the flip rod 223 drives the fixture seat 23 to rotate. The mobile phone on the fixture seat 23 rotates with the fixture seat 23, thereby realizing the quick conversion between the front and side of the mobile phone, so as to facilitate the subsequent welding of the front and side of the mobile phone. When it is necessary to change the fixture seat 23 according to the mobile phone model, since the fixture seat 23 is detachably mounted on the flip rod 223, the fixture seat 23 can be quickly disassembled and replaced.

[0028] By integrating the transfer drive assembly 21 and the flip drive assembly 22 into one unit, the mobile phone can efficiently complete position movement and angle flipping during assembly, reducing intermediate steps and equipment quantity, and improving production efficiency. By employing the flip drive device 222 and the flip rod 223, the fixture seat 23 is detachably mounted on the flip rod 223. The flip drive device 222 drives the flip rod 223 to rotate, and the flip rod 223 drives the fixture seat 23 to rotate, realizing the conversion of the front and side of the mobile phone, which facilitates quick and easy welding conversion between the front and side of the mobile phone. The fixture seat 23 is detachable, which is convenient to replace according to the size and shape of different mobile phone models, enhancing the versatility and adaptability of the mechanism.

[0029] The transfer drive assembly 21 includes a rotary motor 211 and a turntable 212, with the turntable 212 mounted on the output end of the rotary motor 211; the flip drive assembly 22 and the fixture seat 23 are both four sets, with the four sets of flip drive assemblies 22 and the four sets of fixture seats 23 corresponding one-to-one, and the four sets of flip drive assemblies 22 are evenly distributed around the circumference of the turntable 212.

[0030] The setup of four sets of flip drive components 22 and fixture base 23 enables the equipment to transfer and flip multiple mobile phones simultaneously, achieving multi-station operation and improving production efficiency; the rotary motor 211 drives the turntable 212 to rotate continuously, enabling continuous transfer of mobile phones, reducing downtime in the production process, and further improving production efficiency.

[0031] The flipping drive device 222 includes a flipping drive cylinder 2221 and a rocker arm 2222. The upper end of the rocker arm 2222 is hinged to the output end of the flipping drive cylinder 2221, and the lower end of the rocker arm 2222 is sleeved on one end of the flipping rod 223. The flipping drive cylinder 2221 drives the rocker arm 2222 to swing, and the swinging of the rocker arm 2222 causes the flipping rod 223 to rotate on the support 221.

[0032] The lower end of the rocker arm 2222 is provided with a square groove 22221, and one end of the flipping rod 223 is square. The square groove 22221 matches the square end of the flipping rod 223. The rocker arm 2222 is sleeved on one end of the flipping rod 223 through the square groove 22221.

[0033] The lower end of the rocker arm 2222 is provided with a gap 22222 for adjustment. The gap 22222 is connected to the square groove 22221. An upper connecting hole 22223 and a lower connecting hole 22224 are provided at the position of the rocker arm 2222 corresponding to the gap 22222. The upper connecting hole 22223 and the lower connecting hole 22224 are passed through by bolts.

[0034] The flip drive cylinder 2221 can precisely control the swing amplitude and speed of the rocker arm 2222, and thus precisely control the rotation angle of the flip rod 223, achieving precise adjustment of the front and side flip angles of the mobile phone to meet the requirements of different assembly processes. The combination of cylinder and rocker arm 2222 results in a relatively simple structure, easy manufacturing and maintenance, and a stable and reliable transmission process, reducing the probability of failure. The square fit ensures that the rocker arm 2222 reliably transmits power to the flip rod 223 when swinging, avoiding slippage and ensuring the accuracy and stability of the flipping action. The design of the square groove 22221 makes the installation and disassembly of the rocker arm 2222 and the flip rod 223 more convenient and quick, facilitating equipment debugging and maintenance. By adjusting the tightness of the bolts, the size of the gap 22222 can be changed, thereby fine-tuning the fit between the square groove 22221 and the flip rod 223 to adapt to different working conditions and assembly errors, improving the flexibility and reliability of the equipment.

[0035] The support 221 is vertically provided with a vertical limiting post 2211 for limiting the jig seat 23 when it is placed flat and a horizontal limiting post 2212 for limiting the jig seat 23 when it is placed vertically. The jig seat 23 can rotate to abut against the vertical limiting post 2211 or the horizontal limiting post 2212.

[0036] The vertical limiting post 2211 and the horizontal limiting post 2212 precisely limit the flat and vertical positions of the fixture seat 23, respectively, ensuring the accurate position of the mobile phone in different states and providing a reliable foundation for subsequent assembly operations. The limiting posts can prevent the fixture seat 23 from rotating excessively, avoid damage to the equipment, and extend the service life of the equipment.

[0037] The flipping rod 223 includes, from left to right, a first rotating part 2231, a mounting part 2232, a second rotating part 2233, and a connecting part 2234. The first rotating part 2231 and the second rotating part 2233 are rotatably mounted on both sides of the support 221, the fixture seat 23 is detachably mounted on the mounting part 2232, and the connecting part 2234 is sleeved on the lower end of the rocker arm 2222.

[0038] The first rotating part 2231 and the second rotating part 2233 are respectively installed on both sides of the support 221, making the flipping rod 223 more stable during rotation, reducing swaying and offset, and improving the flipping accuracy; the mounting part 2232 facilitates the installation and disassembly of the fixture seat 23, and makes it easy to replace different fixture seats 23 to adapt to different mobile phone models.

[0039] The usage method and principle of this transfer mechanism are as follows: The transfer drive assembly moves the flip drive assembly and the fixture base to change position, thereby moving the mobile phone on the fixture base to meet the positional requirements during mobile phone assembly. The flip drive device drives the flip rod to rotate, and the fixture base is detachably mounted on the flip rod. The rotation of the flip rod causes the fixture base to rotate, and the mobile phone on the fixture base rotates with the fixture base, thereby realizing the quick conversion between the front and side of the mobile phone, so as to facilitate the subsequent welding of the front and side of the mobile phone. When it is necessary to change the fixture base according to the mobile phone model, the fixture base can be quickly disassembled and replaced because it is detachably mounted on the flip rod.

[0040] The copper sheet feeding and positioning mechanism 30 includes a feeding assembly 31 for feeding copper sheets and a positioning assembly 32 for positioning copper sheets, wherein: The feeding assembly 31 has a movable vacuum nozzle 311 for holding copper sheets; the positioning assembly 32 includes a mounting base 321, a feeding plate 322 for placing copper sheets, and a positioning device 323 for positioning the copper sheets on the feeding plate 322; the feeding plate 322 is located on the mounting base 321, and the vacuum nozzle 311 movably feeds copper sheets onto the feeding plate 322; the positioning device 323 is disposed on the mounting base 321, and the output end of the positioning device 323 corresponds to the copper sheet on the feeding plate 322.

[0041] The vacuum nozzle 311 picks up the copper sheet and moves it to the feeding plate 322. The vacuum nozzle 311 feeds the copper sheet onto the feeding plate 322. Since the positional accuracy of the copper sheet cannot be guaranteed each time it is fed, the guiding position of the copper sheet on the feeding plate 322 needs to be adjusted to achieve positioning. The output end of the positioning device 323 corresponds to the copper sheet on the feeding plate 322. The positioning device 323 is used to position the copper sheet on the feeding plate 322 to ensure the positional accuracy of the copper sheet.

[0042] The automated feeding and positioning of copper sheets is achieved by using the feeding component 31 and the positioning component 32, which improves work efficiency and reduces labor costs. The movable vacuum nozzle 311 is used to hold and release the copper sheets, meeting the requirements for feeding and releasing the copper sheets. The copper sheets are placed using the feeding plate 322, and the positioning device 323 is used to guide and position the copper sheets on the feeding plate 322, ensuring the positional accuracy of the copper sheets on the feeding plate 322, which is convenient for the positional accuracy during subsequent mobile phone assembly.

[0043] The feeding assembly 31 also includes a feeding horizontal drive device 312, a feeding vertical drive device 313, and a feeding vertical drive device 314. The feeding vertical drive device 313 is installed at the output end of the feeding horizontal drive device 312, the feeding vertical drive device 314 is installed at the output end of the feeding vertical drive device 313, and the vacuum nozzle 311 is installed at the output end of the feeding vertical drive device 314.

[0044] By employing a horizontal feeding drive device 312, a vertical feeding drive device 313, and a vertical feeding drive device 314, the vacuum nozzle 311 can move freely in three-dimensional space, flexibly picking up copper sheets from different positions and accurately feeding them to designated positions, thus improving the flexibility and adaptability of feeding and meeting the layout and feeding requirements of different mobile phone assembly production lines.

[0045] The vertical feeding drive device 314 includes a rotary drive motor 3141 and a belt drive component 3142. The rotary drive motor 3141 is installed at the output end of the vertical feeding drive device 313, the belt drive component 3142 is installed at the output end of the rotary drive motor 3141, and the vacuum nozzle 311 is fastened to the output end of the belt drive component 3142.

[0046] The belt drive component 3142 includes a drive pulley 31421, a driven pulley 31422, and a drive belt 31423. The drive pulley 31421 is sleeved on the output end of the rotary drive motor 3141, the driven pulley 31422 is located below the drive pulley 31421, and the drive belt is looped around the drive pulley 31421 and the driven pulley 31422. The vacuum nozzle 311 is fastened to the drive belt 31423.

[0047] There are two sets of vertical feeding drive devices 314 and three vacuum nozzles 311. The three vacuum nozzles 311 are fastened to the transmission belts 31423 on the two sets of vertical feeding drive devices 314. The two sets of vertical feeding drive devices 314 drive the three vacuum nozzles 311 to move vertically.

[0048] A rotary drive motor 3141 drives the drive wheel 31421 to rotate, which in turn drives the driven wheel 31422 via a transmission belt 31423, thus achieving the vertical lifting and lowering of the vacuum nozzle 311. Belt drive features smooth transmission and low noise, enabling rapid and efficient lifting and lowering of the vacuum nozzle 311, improving feeding efficiency. The belt drive component 3142 has a relatively simple structure, occupies little space, and is easy to install and maintain, making the entire feeding assembly 31 more compact and saving production line space. Two sets of vertical feeding drive devices 314 simultaneously drive three vacuum nozzles 311 to move vertically, allowing for the simultaneous suction of multiple copper sheets and feeding operations, improving feeding speed and efficiency, and meeting the needs of large-scale mobile phone assembly production.

[0049] The positioning component 32 includes a positioning drive cylinder 3231 and a positioning plate 3232. The positioning drive cylinder 3231 is mounted on the mounting base 321, and the positioning plate 3232 is mounted on the output end of the positioning drive cylinder 3231. The positioning plate 3232 is movably located on the mounting base 321 and is movably abutting against the copper sheet on the feeding plate 322.

[0050] The mounting base 321 is inclinedly provided with guide rails 3233 for guiding purposes. The positioning plate 3232 is slidably located above the guide rails 3233. There are two guide rails 3233, which correspond to the two sides of the positioning plate 3232 respectively. The two guide rails 3233 are arranged in parallel, and the inclination angle of the two guide rails 3233 is 45 degrees. The positioning plate 3232 is guided by the two guide rails 3233.

[0051] The feeding plate 322 is provided with a feeding block 3221 for placing copper sheets, and the positioning plate 3232 is provided with a guide block 32321 for guiding the copper sheets. The guide block 32321 is movable and abuts against the copper sheets on the feeding block 3221.

[0052] The front end of the feeding block 3221 has a placement groove 32211 that matches the copper sheet, and the front end of the guide block 32321 has a bent guide portion 32322. The guide portion 32322 can move to abut and guide the copper sheet on the placement groove 32211. There are several feeding blocks 3221 and guide blocks 32321.

[0053] The positioning drive cylinder 3231 can automatically drive the positioning plate 3232 to move, realizing automatic positioning of the copper sheet on the feeding plate 322, reducing manual intervention and improving the accuracy and consistency of positioning. Two parallel and 45-degree inclined guide rails 3233 provide precise guidance for the positioning plate 3232, enabling the positioning plate 3232 to maintain a stable trajectory during movement, ensuring that the positioning plate 3232 can accurately abut against the copper sheet on the feeding plate 322, thus improving the positioning accuracy. The guide rails 3233 guide from both sides of the positioning plate 3232, effectively preventing the positioning plate 3232 from shaking or shifting during movement, enhancing the stability of the positioning process. The placement slot 32211 of the feeding block 3221 matches the copper sheet, facilitating the placement of the copper sheet. The bent guide part 32322 at the front end of the guide block 32321 can play a guiding role when it comes into contact with the copper sheet, accurately guiding the copper sheet to the designated position, further improving the positioning accuracy of the copper sheet; the setting of several feeding blocks 3221 and several guide blocks 32321 can simultaneously place and position multiple copper sheets, improving the positioning efficiency and facilitating mass production.

[0054] The usage method and principle of the copper sheet feeding and positioning mechanism are as follows: The vacuum nozzle picks up the copper sheet and moves it to the feeding plate. The vacuum nozzle feeds the copper sheet onto the feeding plate. Since the positional accuracy of the copper sheet cannot be guaranteed each time it is fed, the guide position of the copper sheet on the feeding plate needs to be adjusted to achieve positioning. The output end of the positioning device corresponds to the copper sheet on the feeding plate.
