[0023] Reference Figures 1 to 10 As shown, a mobile phone case back panel dispensing machine is provided, including a machine base 1. A back panel transfer mechanism 2 is provided on one side of the machine base 1. A back panel loading mechanism 3, a back panel dispensing mechanism 4, a back panel angle confirmation mechanism 5, and a turntable mechanism 6 are provided on one side of the back panel transfer mechanism 2. The back panel loading mechanism 3 is located on one side of the back panel dispensing mechanism 4, the back panel angle confirmation mechanism 5 is located on the other side of the back panel dispensing mechanism 4, and the turntable mechanism 6 is located on one side of the back panel angle confirmation mechanism 5. A mobile phone case loading mechanism 7 and a unloading mechanism 8 are provided on the side of the turntable mechanism 6 away from the back panel transfer mechanism 2.

[0024] In this embodiment, a transparent protective door is provided around the outer periphery of the machine 1 to protect the various mechanisms on the machine 1. A computer device is also provided connected to each mechanism to monitor its operation. The fixture containing the phone case is placed on the phone case loading mechanism 7, and then transferred to the turntable mechanism 6. The backplate is taken out from the backplate loading mechanism 3 by the backplate transfer mechanism 2 and placed in the backplate dispensing mechanism 4 for dispensing. After dispensing, the backplate transfer mechanism 2 moves the backplate to the backplate angle confirmation mechanism 5 to take a picture of the backplate to confirm the angle, so that the turntable mechanism 6 can rotate to the appropriate angle. After taking the picture, the backplate is transferred to the turntable mechanism 6, and the backplate is fixed to the phone case. Finally, it flows out through the unloading mechanism 8. This utility model achieves the combination of the backplate and the phone case through automation, reducing the product defect rate, improving overall efficiency, and reducing labor costs.

[0025] In one embodiment of this utility model, the backplate transfer mechanism 2 includes a first guide rail 21 and two sliding adsorption components 22. The two sliding adsorption components 22 are movably disposed on the first guide rail 21. One sliding adsorption component 22 can slide from the backplate loading mechanism 3 to the backplate dispensing mechanism 4, and the other sliding adsorption component 22 can slide from the backplate dispensing mechanism 4 to the backplate angle confirmation mechanism 5 and the turntable mechanism 6 in sequence. The first guide rail 21 is connected to the first movable block 24 through the connecting frame 23. A second guide rail 25 is provided on the machine base 1, and the first movable block 24 is movably disposed on the second guide rail 25 so that the first guide rail 21 can move away from or close to the backplate loading mechanism 3.

[0026] Furthermore, the sliding adsorption assembly 22 includes a horizontally movable slider 221 and at least two rotary cylinders 222. The slider 221 is movably mounted on the first guide rail 21, and a vertical slide rail 223 is provided on the slider 221. A liftable connecting plate 224 is provided on the slide rail 223. The rotary cylinders 222 are fixedly mounted on the connecting plate 224. The rotating end of the rotary cylinders 222 is connected to a suction cup rod 225, and at least two vacuum suction cups 226 are provided on the suction cup rod 225.

[0027] In this embodiment, the second guide rail 25 is set on the machine base 1, and the first movable block 24 can move back and forth on the second guide rail 25 so that the sliding adsorption component 22 can move away from or closer to the back plate loading mechanism 3, which facilitates the sliding adsorption component 22 to transfer the back plate. The sliding adsorption component 22 can also move along the length direction of the first guide rail 21 so that the sliding adsorption component 22 can move to the back plate loading mechanism 3, the back plate dispensing mechanism 4, the back plate angle confirmation mechanism 5 and the turntable mechanism 6 to combine the back plate with the mobile phone case. It can also move along the vertical direction of the slide rail 223 to facilitate the picking and placing of the back plate.

[0028] In one embodiment of this utility model, the back plate feeding mechanism 3 includes a back plate placement plate 31, on which at least two partitions 32 are provided to form at least two back plate feeding spaces. An electric screw device 33 is provided at the bottom of the back plate placement plate 31, and a fixed base plate 34 is movably provided on the electric screw device 33. A push rod 35 is provided on the fixed base plate 34. A slot is provided on the back plate placement plate 31 to cooperate with the push rod 35. The push rod 35 passes through the slot and moves back and forth in the slot. A movable push bar 36 is provided on the side of the back plate placement plate 31 away from the partitions 32. A groove space is provided on the back plate placement plate 31 for the push bar 36 to move back and forth. A back plate placement plate slide rail 37 is also provided on the back plate placement plate 31. A sliding connecting plate 38 is movably provided on the back plate placement plate slide rail 37. The push bar 36 is connected to the back plate placement plate cylinder 39 through the sliding connecting plate 38.

[0029] In this embodiment, the back plate is placed in the back plate loading space. Before placement, the fixed base plate 34 is moved by the electric screw device 33, which drives the pusher rod 35 to move away from the partition 32. The back plate placement plate cylinder 39 moves the pusher bar 36 towards the back plate placement plate cylinder 39 through the sliding connecting plate 38, thereby increasing the area of ​​the back plate loading space. At this time, the back plate can be placed for material preparation. After placement, the pusher bar 36 moves towards the partition 32 through the back plate placement plate cylinder 39, and the pusher rod 35 moves towards the partition 32 under the action of the electric screw device 33. This allows the placed back plates to be stacked neatly, making it easy for the back plate transfer mechanism 2 to remove them. When the back plate transfer mechanism 2 needs to remove the back plate, the pusher rod 35 and the pusher bar 36 will move slightly away from the edge of the back plate, so that the back plate transfer mechanism 2 can easily remove the back plate.

[0030] In one embodiment of this utility model, the backplate dispensing mechanism 4 includes a dispensing machine 41 and a positioning plate 42. The dispensing machine 41 is provided with an XY-axis slider 411 that can move along the XY axis. A shim is provided on the XY-axis slider 411. The positioning plate 42 is provided on the shim. The dispensing machine 41 is provided with a movable connecting block 412 that can move along the XZ axis. A hot melt dispensing head is fixedly provided on the movable connecting block 412. The dispensing machine 41 is provided with a waste trough 413, which is located below the positioning plate 42.

[0031] In this embodiment, the back plate is removed from the back plate loading mechanism 3 and transferred to the back plate dispensing mechanism 4. The back plate is placed on the positioning groove of the positioning plate 42, which has a notch to facilitate the movement of the vacuum suction cup 226. The hot melt dispensing head is activated, and the XY axis slider 411 and the movable connecting block 412 cooperate to apply glue to the edge of the back plate. The vacuum suction cup 226 is then taken to the next process. The vacuum suction cup 226 of the sliding adsorption assembly 22 passes through the raised block, allowing the vacuum suction cup 226 to pick up the other side of the back plate that has not been coated with glue, and then moves out through the notch. The vacuum suction cup 226 will not touch the area coated with glue when adsorbing. Preferably, if the dispensing efficiency is slow, more hot melt dispensing heads can be added to speed up the dispensing efficiency.

[0032] In one embodiment of this utility model, the back panel angle confirmation mechanism 5 includes a first light source 51 and a fixed bracket 52. The fixed bracket 52 is fixedly installed on the machine base 1. Two height adjustment components 53 are provided on the fixed bracket 52. One height adjustment component 53 is connected to the first light source 51 through a light source mounting plate. A through hole is opened in the middle of the first light source 51. A first camera 54 for angle compensation is provided below the first light source 51. The first camera 54 is connected to the other height adjustment component 53 through a first camera fixing plate.

[0033] In this embodiment, the first camera 54 is a CCD camera. The second camera 635 on the turntable mechanism 6 first takes a picture of the phone case without a back panel, and then the first camera 54 takes a picture of the angle position of the back panel. If the angle position of the phone case is different from the angle position of the back panel captured by the first camera 54, an alarm system will be triggered and an alarm sound will be heard, thereby reducing defective products. The vacuum suction cup 226 moves the back panel with glue applied to it above the first light source 51, waiting for the first camera 54 to take a picture for confirmation. Only one picture of the angle position of the back panel can be taken at a time. The pictures are uploaded to the computer and automatically processed and compared. When the back panel is placed on the phone case, the angle position of the phone case is consistent with the angle position of the back panel, so that there will be no deviation during placement. If there are two or more back panels on the back panel transfer mechanism 2, only one back panel is placed at a time. The other back panel is rotated upward by the rotary cylinder 222, away from the phone case. After the previous back panel is placed, it is rotated back and placed on the corresponding phone case.

[0034] Preferably, the height adjustment component 53 includes a sliding block that can slide on the fixed bracket 52. The sliding block is provided with a fixing device to fix the sliding block after it moves. The fixing device can be locked by tightening bolts or by other self-locking methods.

[0035] In one embodiment of the present invention, the turntable mechanism 6 includes a turntable 61 and a turntable motor 62. The turntable 61 is connected to the turntable motor 62 via a coupling. The turntable 61 can rotate at any angle. Four evenly distributed jig plates 65 are provided on the turntable 61. A jig plate angle confirmation component 63 and a back plate pressing component 64 are provided on the outer periphery of the turntable 61.

[0036] Furthermore, the jig plate angle confirmation component 63 is disposed on one side of the back plate angle confirmation mechanism 5. The jig plate angle confirmation component 63 includes a first bracket 631 and a first fixing plate 632. The first fixing plate 632 is fixedly installed on the machine base 1. A first slide rail 633 is provided on the first fixing plate 632. A first slider 634 is movably disposed on the first slide rail 633. The first bracket 631 is fixedly disposed on the first slider 634. The other end of the first bracket 631 is connected to a second camera 635 for angle compensation through a first connecting plate. A second light source 636 is provided below the second camera 635. A circular hole for the second camera 635 to take pictures is opened in the middle of the second light source 636. A self-locking bolt is provided on the first slider 634 for fixing the first slider 634.

[0037] The back plate clamping assembly 64 is located on one side of the fixture plate angle confirmation assembly 63. The back plate clamping assembly 64 includes a U-shaped base plate 641 fixedly mounted on the machine base 1 and a pressure plate 642 that can move up and down. Two guide columns 643 are provided on the U-shaped base plate 641. A linear bearing that cooperates with the guide columns 643 is provided on the pressure plate 642 so that the pressure plate 642 can move back and forth along the length direction of the guide columns 643. A top plate 644 is fixedly connected to the end of the guide column 643 away from the U-shaped base plate 641. A pressure plate cylinder 645 is provided on the top plate 644. The telescopic end of the pressure plate cylinder 645 is connected to the pressure plate 642.

[0038] In this embodiment, the second camera 635 is also a CCD camera. The second camera 635 first takes a picture of the angle position of the phone case without the back panel, and then the first camera 54 takes a picture of the back panel with glue. The pictures from the two cameras are uploaded to the computer for comparison. If the edges of the back panel and the phone case are aligned, the vacuum suction cup 226 is moved to place the back panel onto the corresponding phone case. After the back panel is placed on the phone case, it is rotated to the back panel pressing assembly 64 by the turntable 61. The pressing plate cylinder 645 presses the pressing plate 642 downward, so that the back panel just placed on the phone case is more firmly attached to the phone case. After pressing, the turntable 61 rotates the phone case to the unloading mechanism 8 to wait for unloading.

[0039] In one embodiment of the present invention, the unloading mechanism 8 is disposed on one side of the back plate pressing assembly 64. The unloading mechanism 8 includes an unloading robot 81 and a fixed frame 82. The fixed frame 82 is disposed on the machine base 1, and the other end of the fixed frame 82 is provided with an unloading guide rail 83. The unloading robot 81 is movably disposed on the unloading guide rail 83.

[0040] In this embodiment, the unloading robot 81 has a second cylinder and a second parallel finger cylinder equipped with a clamping plate. After the mobile phone case completes the pressing process, the turntable 61 rotates to the unloading mechanism 8. At this time, the unloading robot 81 grabs the mobile phone case on the turntable 61 and completes the unloading.

[0041] In one embodiment of this utility model, the mobile phone case feeding mechanism 7 includes a feeding conveyor belt 71 and a feeding robot. The feeding conveyor belt 71 cooperates with the feeding robot. The feeding robot includes a support column 721 and a parallel finger cylinder 722. The support column 721 is fixedly mounted on the machine base 1. The other end of the support column 721 is fixedly connected to a horizontally arranged feeding guide rail 72. A movable feeding slider 723 is provided on the feeding guide rail 72. A first cylinder 724 is provided on the feeding slider 723. The telescopic end of the first cylinder 724 is fixedly connected to an adapter plate 725. The parallel finger cylinder 722 is fixedly mounted on the adapter plate 725. A clamping plate 726 is installed on the movable end of the parallel finger cylinder 722.

[0042] In this embodiment, the fixture shell containing the mobile phone case is placed on the feeding conveyor belt 71 and transferred to the feeding robot. The feeding robot picks up the fixture shell and places it on the fixture plate 65 of the turntable 61 (the fixture plate 65 is provided with a fixing groove that cooperates with the fixture shell for positioning). After placement, the turntable 61 rotates to the fixture plate angle confirmation component 63 to start working.

[0043] This invention uses a vacuum suction cup 226 to remove the backplate from the backplate feeding mechanism 3 and place it on the positioning plate 42 of the backplate dispensing mechanism 4. A hot melt dispensing head is used to apply adhesive to the edge of the backplate. After dispensing, the vacuum suction cup 226 on another sliding adsorption component 22 sucks up the backplate and moves it above the first light source 51. At this time, the phone case is also moving synchronously on the feeding conveyor belt 71. A feeding robot takes the fixture containing the phone case from the feeding conveyor belt 71 and places it on the fixture plate 65 of the turntable 61. The turntable 61 is rotated so that the fixture is positioned at the fixture plate angle confirmation component 63. At this time, the second camera 635 first takes a picture of the fixture containing the phone case, and then transmits the picture to a computer for confirmation of the phone case. After the angle and position are determined, the back panel above the first light source 51 is photographed by the first camera 54. The photographed image is transmitted to the computer and compared with the image taken by the second camera 635. If the edge of the phone case does not coincide with the edge of the back panel, an alarm is triggered. If the edge of the phone case coincides with the edge of the back panel, the back panel is moved and placed on the phone case. Each time it is placed, another vacuum suction cup 226 is rotated upward by the rotary cylinder 222 so that it does not contact the corresponding phone case. After the previous back panel is placed, the vacuum suction cup 226 is rotated back to its original position by the rotary cylinder 222, thus placing the back panel on the phone case. The other vacuum suction cup rotates upward to avoid the other accidentally touching the other during installation, which may cause one of the phone cases to be misaligned with the back panel. After the phone cases are placed on the back panel, the turntable 61 rotates to the back panel clamping assembly 64. The pressure plate cylinder 645 controls the pressure plate 642 to press the phone case and the back panel together, making them more secure. After the pressure plate 642 rises, the turntable 61 rotates the phone case to the unloading mechanism 8, waiting for the unloading robot 81 to pick it up, thus completing the entire process. This phone case back panel dispensing machine automates the bonding of the back panel and the phone case, reducing the product defect rate, improving overall efficiency, and reducing labor costs.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
