[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] like Figure 1As shown, an embodiment of this application provides a mobile phone back cover and rear camera assembly device, including a frame 1. The frame 1 is provided with a conveying mechanism 2 for conveying a carrier mechanism 11. The carrier mechanism 11 is used to fix the rear camera. Along the conveying mechanism 2, there are sequentially arranged a dispensing mechanism 3 for dispensing glue to the rear camera, an assembly mechanism 4 for assembling the back cover onto the rear camera, and a pressure holding mechanism 5 for holding the assembled product under pressure. The conveying mechanism 2 is sequentially provided with a dispensing station 6, a buffer station 7, and an assembly pressure holding station 8. On one side of the conveying mechanism 2, there is a tray loading mechanism 9 for loading the back cover and a defective product unloading mechanism 10 for unloading defective products.

[0033] like Figure 2 As shown, the carrier mechanism 11 includes a carrier 111 for fixing the rear camera and a detachable pressure-holding cover 112. The pressure-holding cover 112 is positioned and engaged with one end of the carrier 111, and the other end of the carrier 111 is provided with a pressure head 113. The pressure head 113 is rotatably connected to the carrier 111 through an elastic component.

[0034] Specifically, the rear camera is fixed to the carrier 111. The conveying mechanism 2 transports the carrier 11 to the dispensing station 6. The lifting and positioning mechanism 61 of the dispensing station 6 positions the carrier 11. The first camera assembly 36 of the dispensing mechanism 3 takes pictures of the dispensing position of the rear camera on the carrier 111. Then, the spray valve 34 of the dispensing mechanism 3 dispenses glue to the rear camera on the carrier 111. After the dispensing is completed, the first camera assembly 36 re-inspects the glue path on the rear camera. Then, the conveying mechanism 2 transports the carrier 11 and the rear camera to the buffer station 7 for buffering. After the buffer is buffered, the carrier mechanism 11 drives the rear camera to be transported to the assembly station. The lifting and positioning mechanism 61 of the assembly station positions the carrier mechanism 11. Then, the second camera component 47 of the assembly mechanism 4 takes a picture of the rear cover on the tray of the pallet loading mechanism 9 for positioning. Then, the pressing component 46 of the assembly mechanism 4 picks up the rear cover on the tray of the pallet loading mechanism 9. When the assembly mechanism 4 moves the rear cover to directly above the carrier 111, the second camera component 47 takes a picture of the carrier 111 for positioning. After the position is determined, the pressing component 46 assembles the rear cover onto the rear camera. The second camera assembly 47 re-inspects the assembled product. If the re-inspection fails, the assembly mechanism 4 transfers the defective product to the defective product unloading mechanism 10. If the re-inspection passes, the clamping component 55 of the pressure holding mechanism 5 clamps the pressure holding cover 112 on the carrier mechanism 11. The pressure holding mechanism 5 drives the clamping component 55 to move directly above the carrier 111. The clamping component 55 covers the pressure holding cover 112 on the carrier 111, pressurizes the rear cover and the rear camera, and moves them to the next workstation.

[0035] In the above structure, the conveying mechanism 2, dispensing mechanism 3, assembly mechanism 4, and pressure holding mechanism 5 work together to achieve automated assembly of the rear cover and rear camera. Furthermore, the carrier mechanism 11, including a carrier 111 and a pressure holding cover plate 112, improves the efficiency of dispensing, assembly, and pressure holding for the rear camera. This assembly equipment not only achieves automated assembly and pressure holding but also improves the accuracy of the assembled product, increases the yield rate, and enhances production efficiency.

[0036] like Figure 3 and Figure 4 As shown, in one embodiment, the dispensing station 6, buffer station 7, and assembly pressure holding station 8 of the mobile phone back cover and rear camera assembly equipment all include a lifting and positioning mechanism 61 for positioning and lifting the carrier mechanism 11, a limiting mechanism 62 for limiting the carrier mechanism 11, and a check mechanism 63 for preventing the carrier mechanism 11 from returning. The lifting and positioning mechanism 61 includes a support base 611, a first lifting cylinder 612, and a base plate 613. The support base 611 is symmetrically provided with elastic pressure plates 614 for positioning the top of the carrier mechanism 11. The base plate 613 is provided with two positioning columns 615. The driving end of the first lifting cylinder 612 is connected to the base plate 613. The first lifting cylinder 612 is used to drive the base plate 613 to drive the two positioning columns 615 to position the carrier mechanism 11. When the carrier mechanism 11 moves to the dispensing station 6, the limiting mechanism 62 limits the carrier mechanism 11, and the check mechanism 63 prevents the carrier mechanism 11 from flowing back. The first lifting cylinder 612 of the lifting and positioning mechanism 61 drives the base plate 613 to move the two positioning pins 615 upward and extend them into the positioning holes of the carrier 111 to position the carrier 111. The elastic pressure plate 614 presses the two ends of the carrier 111 to position the carrier 111 and prevent it from moving, thus ensuring the accuracy of dispensing. The carrier mechanism 11 flows sequentially to the buffer station 7 and the assembly and pressure holding station 8, where the buffer station 7 and the assembly and pressure holding station 8 respectively position the carrier mechanism 11. This setup improves the positioning strength and efficiency of the carrier mechanism 11, thereby improving the accuracy of dispensing, assembly, and pressure holding.

[0037] like Figure 5As shown, in one embodiment, the assembly and pressure holding station 8 of the mobile phone back cover and rear camera assembly equipment further includes a toggle assembly 81 for releasing the carrier 111 and the product, and a spinning assembly 82 for driving the pressure head 113 to rotate and press. The toggle assembly 81 includes a toggle block 811, a first slide cylinder 812 that moves up and down, and a second slide cylinder 813 that moves horizontally. The first slide cylinder 812 is mounted on the support base 611. The driving end of the first slide cylinder 812 is connected to the second slide cylinder 813, and the driving end of the second slide cylinder 813 is connected to the toggle block 811. The base plate 613 is provided with a through hole for the toggle block 811 to move. The spinning assembly 82 includes a second lifting cylinder 821, a rotating cylinder 822, and a rotating column 823 for positioning the pressure head 113. The driving end of the second lifting cylinder 821 is connected to the rotating cylinder 822, and the driving end of the rotating cylinder 822 is connected to the rotating column 823. When the carrier mechanism 11 moves to the assembly and pressure holding station 8, the assembly mechanism 4 assembles the back cover onto the rear camera. The second camera assembly 47 then takes a picture of the assembled product for inspection. If the inspection fails, the first slide cylinder 812 drives the second slide cylinder 813 to move the toggle block 811 upward. The second slide cylinder 813 drives the toggle block 811 to open the carrier 111, causing the carrier 111 to release the rear camera and the back cover. The assembly mechanism 4 then moves the defective product to the defective product unloading mechanism 10. If the inspection passes, the second lifting cylinder 821 drives the rotating cylinder 822 to extend the rotating column 823 into the carrier 111 to limit the bottom of the elastic component and push the pressure head 113 out to a specified height. The rotating cylinder 822 drives the rotating column 823 to rotate the pressure head 113 to above the tail end of the back cover. Then, under the force of the elastic component, the tail end of the back cover is pressed tightly to prevent the back cover from loosening. The pawl assembly 81 is designed to facilitate the separation of the carrier 111 and the product. The spin-forming assembly 82 is designed to facilitate the clamping of the rear cover.

[0038] like Figure 6 and Figure 7As shown, in one embodiment, the dispensing mechanism 3 of the mobile phone back cover and rear camera assembly equipment includes a support frame 31, a three-axis drive mechanism 32, a fixing plate 33, a spray valve 34, an adhesive assembly 35, and a first camera assembly 36. The three-axis drive mechanism 32 is mounted on the support frame 31, and its drive end is connected to the fixing plate 33. The spray valve 34 and the first camera assembly 36 are mounted on the fixing plate 33. The adhesive assembly 35 includes a fixing seat 351. Mounted on the frame 1 and located on one side of the conveying mechanism 2, the fixed base 351 is equipped with a glue discharge tank 352, an electronic scale 353 and a glue wiping mechanism 354. The three-axis drive mechanism 32 is used to drive the spray valve 34 to spray the glue in the glue discharge tank 352 onto the glue dispensing position of the rear camera on the carrier 111. The first camera assembly 36 includes a first camera 361 and a first light source 362. The first light source 362 is located directly below the first camera 361 and illuminates the first camera 361. The three-axis drive mechanism 32 drives the fixed plate 33 to move the spray valve 34 and the first camera assembly 36 in the X, Y, and Z axes. The three-axis drive mechanism 32 drives the first camera assembly 36 to take pictures and position the rear camera on the carrier mechanism 11 located at the dispensing station 6. Then, the three-axis drive mechanism 32 drives the spray valve 34 to spray or apply glue to the dispensing position of the rear camera. Next, the three-axis drive mechanism 32 drives the first camera assembly 36 to re-inspect the dispensing position. After the re-inspection is passed, the conveying mechanism 2 drives the carrier mechanism 11 to move to the buffer station 7. The glue assembly 35 provides a fixed amount of glue to the spray valve 34. This setup facilitates the dispensing operation on the rear camera on the carrier mechanism 11, improving the efficiency and accuracy of dispensing.

[0039] like Figure 8As shown, in one embodiment, the pallet loading mechanism 9 of the mobile phone back cover and rear camera assembly equipment includes a transmission component 91 for conveying the pallet, a lifting mechanism 92 for lifting the pallet, and a unloading mechanism 93 for unloading the pallet. The transmission component 91 includes a fixed frame 911, a first motor 912, and a synchronous belt drive component 913. A linear slide rail 914 is provided on the fixed frame 911.

The third lifting cylinder 923 is installed... Mounted on base 921, the drive end of the third lifting cylinder 923 is connected to the top plate 922. The third lifting cylinder 923 is used to drive the top plate 922 to move the guide assembly 924 up and down. The base 921 is located on the synchronous belt drive assembly 913 and slides with the linear slide rail 914. The feeding mechanism 93 is installed at the input end of the transmission assembly 91. The feeding mechanism 93 includes a full material bin 931 for stacking multiple trays full of back covers and an empty material bin 932 for placing empty trays. The full material bin 931 is symmetrically provided with a vertically moving first cylinder 933, a horizontally moving second cylinder 934 and a claw 935 for extending between the trays. The drive end of the first cylinder 933 is connected to the second cylinder 934, and the drive end of the second cylinder 934 is connected to the claw 935. The empty material bin 932 is symmetrically provided with several check blocks 936 for fixing empty trays. The pallets filled with back covers are stacked on the full material hopper 931. The first motor 912 drives the synchronous belt transmission assembly 913 to move the lifting mechanism 92 to the bottom of the pallets filled with back covers. The third lifting cylinder 923 of the lifting mechanism 92 drives the top plate 922 to move upward to support the bottom pallet. At the same time, the first cylinder 933 drives the second cylinder 934 to move upward. The second cylinder 934 drives the claw 935 to extend into the top of the bottom pallet. The first cylinder 933 drives the second cylinder 934 and the claw 935 to lift the remaining pallets. Then, the transmission assembly 91 drives the lifting mechanism 92 to move the bottom pallet to the picking station, where the assembly mechanism 4 picks up the back covers from the pallets. Once all the rear covers in the tray have been sucked up, the transmission assembly 91 drives the lifting mechanism 92 to move the empty antenna tray to the empty material bin 932. The lifting mechanism 92 then drives the tray upwards, lifting multiple check blocks 936 so that the tray is positioned on the check blocks 936. The lifting mechanism 92 then resets, and the empty tray remains on the check blocks 936. The transmission assembly 91 then drives the lifting mechanism 92 to move to the full material bin 931 to continue transferring the bottom tray to the material handling station.This design facilitates the loading of the back cover into the tray, improving the efficiency of the assembly mechanism 4 in picking up the back cover.

After the material-picking head 464 picks up the back cover, the dual-axis drive mechanism 42 drives the material-picking head 464 to move the back cover above the third camera assembly 12. The third camera assembly 12 takes a picture of the back cover on the material-picking head 464 for positioning. Then, the dual-axis drive mechanism 42 drives the back cover to move directly above the carrier mechanism 11. The second camera assembly 47 takes a picture of the assembly position of the carrier 111 and the rear camera. The first linear module 43 drives the material-picking head 464 to move downward. The rotary motor 463 adjusts the assembly angle of the back cover according to the positioning picture. Then, the pressing cylinder 461 drives the material-picking head 464 to press the back cover down and assemble it onto the rear camera of the carrier mechanism 11. This setting greatly improves the assembly accuracy and efficiency of the assembly mechanism 4 for the back cover.

[0041] like Figure 10As shown, in one embodiment, the frame 1 of the mobile phone back cover and rear camera assembly equipment is equipped with a third camera assembly 12 for photographing and positioning the back cover on the assembly mechanism 4. The third camera assembly 12 includes two symmetrically arranged third cameras 121, with a third light source 122 on each side of the two third cameras 121. When the assembly mechanism 4 drives the back cover to move above the third camera 121, the third camera 121 photographs and positions the back cover on the material handling head 464. This arrangement facilitates the rotary motor 463 in adjusting the assembly position of the back cover.

[0042] like Figure 11 As shown, in one embodiment, the pressure-holding mechanism 5 of the mobile phone back cover and rear camera assembly equipment includes a fixed bracket 51, a second linear module 52 that moves along the X-axis, a third cylinder 53 that moves along the Z-axis, a lifting plate 54, and a clamping assembly 55. The second linear module 52 is mounted on the fixed bracket 51, and the driving end of the second linear module 52 is connected to the third cylinder 53. The driving end of the third cylinder 53 is connected to the lifting plate 54. The clamping assembly 55 is mounted on the lifting plate 54. The clamping assembly 55 includes a gripper cylinder 551 and two grippers 552 for clamping both ends of the pressure-holding cover 112. The driving end of the gripper cylinder 551 is connected to the two grippers 552. Two elastic components 553 for pressing the pressure-holding cover 112 are respectively provided between the two grippers 552 and the lifting plate 54. The second linear module 52 drives the third cylinder 53 to move the clamping assembly 55 to directly above the pressure-holding cover 112 of the carrier mechanism 11. Then, the third cylinder 53 drives the clamping assembly 55 to move towards the pressure-holding cover 112. The gripper cylinder 551 drives the two grippers 552 to clamp the clips at both ends of the pressure-holding cover 112, releasing the pressure-holding cover 112 from the carrier 111. The second linear module 52 then moves the pressure-holding cover 112 directly above the carrier 111, causing the pressure-holding cover 112 to close onto the rear cover and rear camera. The gripper cylinder 551 then drives the two grippers 552 to release the clips at both ends of the pressure-holding cover 112, thus securing the pressure-holding cover 112 onto the carrier 111 and maintaining pressure on the rear cover and rear camera. This configuration facilitates the closing of the pressure-holding cover 112 onto the carrier 111, ensuring effective pressure holding.

[0043] like Figure 12As shown, in one embodiment, the defective product unloading mechanism 10 of the mobile phone back cover and rear camera assembly equipment includes a support frame 101, a slide plate 102, a defective product carrier platform 103, a transverse cylinder 104, and a locking assembly 105. The slide plate 102 is slidably engaged with the support frame 101. The transverse cylinder 104 is mounted on the slide plate 102, and the drive end of the transverse cylinder 104 is connected to the defective product carrier platform 103. The locking assembly 105 is mounted on one side of the slide plate 102 and is used to limit the movement position of the slide plate 102. The locking assembly 105 includes a locking cylinder 001 and a locking block 002. The drive end of the locking cylinder 001 is connected to the locking block 002. The slide plate 102 is provided with a limiting groove 003 for the locking block 002 to extend into and limit the movement. The two ends of the slide plate 102 are respectively provided with a baffle 106 and a limiting frame 107 for limiting the movement distance. When the second camera assembly 47 detects that the product is not properly assembled, the material-picking head 464 of the assembly mechanism 4 picks up the assembled defective product and moves it to the defective product carrier table 103. The transverse cylinder 104 drives the defective product carrier table 103 to move horizontally for picking up and unloading. The locking cylinder 001 drives the locking block 002 to extend into the limiting groove 003 of the slide plate 102 to limit the slide plate 102 and prevent it from moving left or right. The baffle 106 and the limiting frame 107 limit the movement distance at both ends of the slide plate 102. This setting facilitates the picking up and unloading of assembled defective products.

[0044] like Figure 3 As shown, in one embodiment, the conveying mechanism 2 of the mobile phone back cover and rear camera assembly equipment includes a conveying frame 21, a drive motor 22, a drive wheel 23, a driven wheel 24, a tensioning wheel assembly 25, and a belt 26 wound around the drive wheel 23, the driven wheel 24, and the tensioning wheel assembly 25. The drive motor 22 is mounted on the conveying frame 21, and its drive end is connected to the drive wheel 23. The drive motor 22 drives the drive wheel 23 to rotate the belt 26 and the driven wheel 24. The tensioning wheel assembly 25 tensions the belt 26. This arrangement facilitates the movement of the drive carrier mechanism 11 and improves the movement efficiency of the carrier mechanism 11.
